[0004] All written material, figures, content and other disclosure
in each of the above-referenced applications is hereby incorporated
by reference.
BACKGROUND OF THE INVENTION
[0005] The present invention relates generally to a locking
apparatus and more specifically it relates to a locking system,
apparatus and method for fostering ease of installation of various
securing devices, as well as controlling access and preventing
unauthorized access to such various securing devices used in, for
example, the gas, water and electric utility services industries,
and those used in other suitable industries as well and it relates
to other aspects features as well as provided herein.
[0006] Electrical service providers generally deliver electricity
to their customers via power lines buried underground or
distributed along poles or towers overhead. The provider's power
lines are usually distributed from a power generation station to
numerous sets of customer lines, so that customers can then use the
power to satisfy their various electrical needs. To measure
delivered power so that customers can be billed in proportion to
their usage, service providers typically terminate their power
lines at a customer's home or business facility through a metered
socket box, various designs for which are well known. Natural gas
and water service providers deliver and meter services in a similar
method.
[0007] For example, one previously known electric meter box
consists of two sets of electrical posts, with a provider's
transmission lines being connected to one set of posts, and the
customer's service lines to the other set. In order to measure the
amount of electricity a customer uses, the meter box is configured
to accept a watt-hour meter or another electricity usage
measurement device, which, when plugged into the socket box,
permits transmission of electricity from the provider to the
customer and allows the amount of transmitted electricity to be
accurately measured, so that the provider can charge the customer
for power usage at an appropriate rate. The electrical service
providers utilize many security apparatus to deter and prevent
tampering with the meter. Typically, these security apparatus are
locked with a barrel lock. This is largely true also for utility
service providers of natural gas and water.
[0008] The present invention is a new type of barrel lock that in
the locked state can be inserted into a securing device without
first unlocking, and then, thereafter, locking after insertion.
Unlocking and re-locking requires a key. The present invention is
distinct from existing devises and products because it can enter
and exit multiple apertures without requiring a key, which an
enables a new method of locking with a keyless insertion rotatable
disk style barrel lock.
[0009] The present invention provides various features and
advantages which are of notable value to the user such as for
example, improvement in key management and security of key access.
It is common for the installation of security devices to be
performed by contractors or employees who then also have control
over the key(s), for example, to perform such services. If this
activity could be performed without a key, then the utility company
could much better manage key security. Current market solutions do
not entirely address this problem. The present invention can work
with electricity meter rings or enclosure lid locking devices,
water or gas meter and transmission locking devices and many other
devices because it can pass through multiple apertures without the
use of a key.
[0010] There remains a need for an apparatus and method for easily
securing at least one structure or a plurality of structures, used
with, for example, a utility service enclosure, or more
particularly, a watthour meter box having a removable cover with
the apparatus being adaptable for use in various
configurations.
[0011] Those of skill in the art will appreciate the example
embodiments of the present invention which addresses the above
needs and other significant needs the solution to which are
discussed hereinafter.

[0078] One aspect of the current invention comprises a method for
retaining a barrel lock able to be inserted and removed from
locking hardware capable of receiving a barrel lock. FIGS. 10a
through 10e show an example embodiment method for retaining a
barrel lock. Referring to FIG. 10 a barrel lock 1 is inserted into
locking hardware 14. Referring to FIG. 10b this causes a retainer
10 to retract as a result of inserting the barrel lock into the
locking hardware 14. The retraction is a result of the interaction
between the retainer 10 and the locking hardware 14. When the
barrel lock is inserted the retainer 10 is forced into recess 3f in
retainer extender 3. Referring to FIG. 10e the retainer 10 is
extended when in an inserted position as shown in FIG. 10e in the
locking hardware 14. The retainer 10 is prevented from retracting
by the retainer extender 3 and specifically by surface 3e, when a
force is exerted on the barrel lock in a direction generally
opposite the direction in which the barrel lock was inserted by
retainer extender 3. Another aspect of the invention comprises a
barrel lock retainer for retaining a barrel lock in locking
hardware capable of retaining a barrel lock such as a meter locking
ring or ring-less meter locking hardware or other locking hardware
as known by those skilled in the art. A barrel lock 1 as shown in
FIG. 1 comprises an example barrel lock retainer. The example
barrel lock has a locked configuration that prevents the barrel
lock from being removed from the hardware in which it is installed
without the use of a proper key; and an unlocked configuration
which allows removal of the barrel lock from the hardware in which
it is installed when unlocked with the proper key. Referring to
FIG. 6, the example embodiment retainer comprises: a retractable
retaining member 10 (in the current example a ball) and a retaining
member extender 3. The retaining member extender is configured to
allow insertion of the barrel lock when the lock is in a locked
configuration as shown in FIG. 7 and prevent removal of the barrel
lock in the locked configuration as shown in FIG. 6. The retaining
member extender 3 is configured to cooperate with the locking
hardware to retract the retaining member 10 by allowing the
retaining member to be urged into the recess 3f in the retaining
member extender 3 when the lock is inserted into the hardware.
[0079] Another aspect of the present invention comprises a barrel
lock installable in locking hardware and the barrel lock has a
locked and an un-locked configuration. FIG. 26 shows an example
barrel lock comprising a retainer shown generally at 2000. The
retainer comprises: a retaining member 210, a biasing member 209
biased to exert a force on the retaining member 210 and a retainer
extender 203. The retainer extender has a reduced cross-section
shown generally at 203f and is configured to allow retraction of
the retaining member 210 as shown in FIG. 27. When the retaining
member is forced in a direction generally opposite to the force
exerted by the biasing member the retaining member 210 moves into
the recess at 203f and retracts to allow the barrel lock to be
inserted without the use of a key.
[0080] Another aspect of the invention comprises a retaining pin
for installation in hardware capable of receiving a retaining pin
as is well known by those skilled in the art. An example embodiment
retaining pin is shown in FIG. 52. The example retaining pin has a
locked configuration as shown in FIG. 53 and an un-locked
configuration as shown in FIG. 54. FIG. 55 shows the retaining pin
in the locked position with the retaining members retracted as
would occur when the retaining pin is inserted into the hardware.
The retaining pin comprises: a uni-directional retaining member
shown generally at 2001 in FIG. 52. The uni-directional retaining
member is configured to interact with the hardware during insertion
of the retaining pin when the retaining pin is in a locked
configuration. During the interaction with the hardware, the
retaining member retracts sufficiently to allow the barrel lock to
be inserted as shown in FIG. 55. The retaining member is configured
to interact with the hardware during attempted removal of the
retaining pin from the hardware when the retaining pin is in a
locked configuration as shown in FIG. 53. The retaining member 804
is biased by the biasing member 807 and 808 in a direction to allow
retainer extender 803 to prevent retraction of the retaining member
804 sufficiently to prevent the barrel lock from being removed.
[0081] Referring generally to FIGS. 1-10, example embodiments of
the present invention are illustrated. In various example
embodiments, the barrel lock may be used with a variety of types of
hardware adapted to receive a barrel lock so as to secure a given
locking device and may be used secure a numerous other types of
locking devices or hardware. In an example embodiment of the
invention, the barrel lock is adapted for use with various types of
hardware capable of receiving a barrel lock as noted. In one
example embodiment, the barrel lock comprises a body, at least one
locking member and a biasing member for biasing the locking member
into an extended mode. In other example embodiments, a plurality of
locking members are provided. When a sufficient external force is
applied to the at least one locking member, the locking member
moves into a retracted mode, such that at least a portion of the
locking member is retracted into the body and such that the barrel
lock may be inserted into the hardware (Hardware may be any of
various types of structure or devices adapted for receiving a
barrel lock. The barrel lock is axially insertable in example
embodiments as noted herein).
[0082] The following provides a description of an example
embodiment of the locking apparatus. The motion of locking members
(or ball bearings 10), in this example embodiment, will be
described longitudinally along the axis of case 1 as proximal and
distal relative to end cap 9; the motion of balls 10 will also be
described radially relative to center axis of case 1. Also, in this
example embodiment, to "recess", "recede" or "retract" shall refer
to travelling toward the case 1 axis and to "extend" shall refer to
travelling away from the case 1 axis.
[0083] Referring to FIGS. 1 and 2, the locking assembly is shown
with ball bearings 10 extended from inside case 1 through slots 30
on opposing sides of case. Ball position boundaries are partially
defined by the following elements of case 1: la, lb, and slot 30
ends 1c and 1d. Retaining protuberances 1a and 1b restrain the
balls within the lock assembly and present a physical boundary
within which balls can recede toward or extend from the case center
axis in an example embodiment. The ball bearings (e.g., 10) track
within the respective slots longitudinally parallel with the case
center axis and are bound by slot 30 ends 1c and 1d.
[0084] The positioning of balls 10 is further constrained by the
geometry of rotor stem 3. Referring to FIG. 8, rotor stem 3 has
four surfaces (3a, 3b, 3c, and 3d) controlling the position and
movement (and behavior) of balls 10. In the present embodiment the
rotor stem or retainer extender 3 has a recess 3f, defined
generally by surfaces 3b, 3c and 3d, for receiving the retaining
members which in the present invention are balls. Surface 3c
defines the boundary of recessing travel of the balls 10 so that
the balls can recede toward access no further than surface 3c.
Surface 3d in cooperation with surface 1d of slot 30 defines the
boundary of proximal longitudinal travel of ball 10. Surface 3a
presents a hard bearing surface and interference with the ball
movement that prevents the balls from recessing.
[0085] Referring to FIG. 6, the balls 10 are shown at the most
extended state. The balls are constrained by surface 3a, surface 1c
of slot 30 and retaining protuberances 1a and 1b. At this most
extended state, the spherical center of balls 10 remains within the
lock case 1. Consequently, any effort to push the lock into and
through an aperture would generate (or render) forces both
proximally longitudinal and radial toward center.
[0086] Referring to FIGS. 6 and 9, sleeve 13 and compression spring
13 cooperatively biases balls 10 toward surface 1c of slot 30.
Sleeve 13 bears on balls 10. Compression spring 13 permits
translation of the sleeve along the case axis and biases toward a
rest position at the most extended position or state as described
in FIGS. 1, 2 and 6. When the keyless insertion lock is pushed into
an aperture, resistance (or reaction forces) from the surfaces or
walls creating the aperture, push against balls 10 and, thereby,
urge balls 10 longitudinally toward the proximal end of the case
and inward toward the case axis. Surface 3a prevents recessing.
However, when this reaction force overcomes the bias of spring 13,
sleeve 12 retracts proximally so that balls 10 move along surfaces
3a. At junction of 3a and 3b along longitudinal movement the in
proximal direction, the balls can and do recede toward case axis
along surface 3b. The balls become fully recessed when contacting
3c and, consequently, have no forces driving them further toward
the axis. Coincidentally, the balls contact surfaces 1d and 3d
preventing further longitudinal travel. As shown in the figures,
cooperative structures are provided to prevent travel; FIGS. 3, 4
& 7 depict the component positions when balls 10 are fully
retracted, which enables free passage through an aperture.
[0087] Upon exiting the aperture, the bias of spring 13 and absence
of outside forces allows the balls 10 to reverse the ravel sequence
described above and return to lowest energy position described in
FIG. 6.
[0088] Pulling the lock back out of an aperture in the locked state
is resisted by surfaces 1c of slot 30 and 3a of rotor 3.
Consequently, the locked lock allows entry into an aperture but
prevents extraction without unlocking in view of the cooperative
configuration and relationship of the locking apparatus
components.
[0089] Other nonlimiting embodiments as well are contemplated
within the present invention. Some possible alternate nonlimiting
embodiments include the following, but are not considered
exhaustive. In one example embodiment, the compression spring 13
and sleeve 12 could be replaced and in many ways with various
structures or different types of materials (flexible plastics,
metals, resilient materials, or other suitable materials). For
instance, a variable pitch spring could eliminate the need for
sleeve 12. Or a leaf spring could be incorporated into the rotor
stem 3 so that the rotor stem could perform requisite functions of
sleeve 12, spring 13 and rotor stem 3. In another example
embodiment, a leaf spring or other biasing mechanism could be
incorporated in a sleeve 12. In another example embodiment, an
independent compression spring for each ball 10 could be used. In
another example embodiment, the biasing arrangement could be
provided by an extension or leaf spring pulling the sleeve toward
the distal end of the rotor stem. Other example embodiments, can
include a single or multiple ball bearings 10 or other components
such as, for example, a leaf spring, urethane spring, o-ring.
[0090] Another example embodiment provides an apparatus adapted to
be mounted to secure at least one enclosure. Other applications
include use with a hasp, truck lock, disposable locks or in various
environments and industries. In an alternate embodiment, the
invention could have an inverted configuration.
[0091] In another example embodiment, the sleeve 12 is equivalent
to any mechanism that bears upon the balls 10 to urge to desired
position of rest. The spring 10 is equivalent to any mechanism that
resist motion and biases balls to desired position of rest as
described above.
[0092] In view of the above and FIGS. 1-20 and also referring to
U.S. Pat. No. 4,742,703, and FIG. 62 (see also FIG. 2 in U.S. Pat.
No. 4,742,703), another example embodiment is provided as noted
below. The reference numerals in FIG. 62 correlate with those as
provided in the above-referenced patent but, in other example
embodiments of the present invention, the referenced structure may
be combined with that shown above in FIGS. 1-20 as noted.
[0093] In another example embodiment, when various types of locking
hardware may be used comprising a rotation restricting stop
surface, wherein the barrel lock comprises: a body comprising a
head and a shank connected to said head; at least one rotation
restricting stop surface located on said body for interaction with
the rotation restricting stop surface of the locking hardware; and
at least one variable-radial-play and radially-retractable retainer
having an acute retaining surface, wherein the radial play allows
the retainer to protrude through said body in a first condition and
retract into said body in a second condition.
[0094] As to a further discussion of the manner of usage and
operation of the present invention and example embodiment herein,
the same should be apparent from the description herein.
[0095] Referring generally to FIGS. 11-20, example embodiments of
the present invention are illustrated. In various example
embodiments, the barrel lock may be used with a variety of types of
hardware adapted to receive a barrel lock so as to secure a given
locking device and may used secure a numerous other types of
locking devices or hardware.
[0096] In an example embodiment of the invention, the barrel lock
is adapted for use with various types of hardware capable of
receiving a barrel lock as noted. In one example embodiment, the
barrel lock comprises a body, at least one locking member and a
biasing member for biasing the locking member into an extended
mode. In other example embodiments, a plurality of locking members
are provided. When a sufficient external force is applied to the at
least one locking member, the locking member moves into a retracted
mode, such that at least a portion of the locking member is
retracted into the body and such that the barrel lock may be
inserted into the hardware (Hardware may be any of various types of
structure or devices adapted for receiving a barrel lock. The
barrel lock is axially insertable in example embodiments as noted
herein).
[0097] The following provides a description of an example
embodiment of the locking apparatus. The motion of locking members
(or ball bearings 110), in this example embodiment, will be
described longitudinally along the axis of case 101 as proximal and
distal relative to end cap 109; the motion of balls 110 will also
be described radially relative to center axis of case 1. Also, in
this example embodiment, to "recess", "recede" or "retract" shall
refer to travelling toward the case 1 axis and to "extend" shall
refer to travelling away from the case 1 axis.
[0098] Referring to FIGS. 21 and 22, the locking assembly is shown
with ball bearings 110 extended from inside case 101 through slots
130 on opposing sides of case. Ball position boundaries are
partially defined by the following elements of case 101: 101a,
101b, and slot 130 ends 101c and 101d. Retaining protuberances 101a
and 101b restrain the balls within the lock assembly and present a
physical boundary within which balls can recede toward or extend
from the case center axis in an example embodiment. The ball
bearings (e.g., 10) track within the respective slots
longitudinally parallel with the case center axis and are bound by
slot 130 ends 101c and 101d.
[0099] The positioning of balls 110 is further constrained by the
geometry of rotor stem 3. Referring to FIG. 8, rotor stem 103 has
four surfaces (103a, 103b, 103c, and 103d) controlling the position
and movement (and behavior) of balls 110. Surface 3c defines the
boundary of recessing travel of the balls 110 so that the balls can
recede toward access no further than surface 103c. Surface 103d in
cooperation with surface 101d of slot 130 defines the boundary of
proximal longitudinal travel of ball 110. Surface 103a presents a
hard bearing surface and interference with the ball movement that
prevents the balls from recessing.
[0100] Referring to FIG. 16, the balls 110 are shown at the most
extended state. The balls are constrained by surface 103a, surface
101c of slot 130 and retaining protuberances 101a and 101b. At this
most extended state, the spherical center of balls 110 remains
within the lock case 101. Consequently, any effort to push the lock
into and through an aperture would generate (or render) forces both
proximally longitudinal and radial toward center.
[0101] Referring to FIGS. 16 and 19, sleeve 112 and compression
spring 113 cooperatively biases balls 110 toward surface 101c of
slot 130. Sleeve 112 bears on balls 110. Compression spring 113
permits translation of the sleeve along the case axis and biases
toward a rest position at the most extended position or state as
described in FIGS. 101, 102 and 106.
[0102] When the keyless insertion lock is pushed into an aperture,
resistance (or reaction forces) from the surfaces or walls creating
the aperture, push against balls 110 and, thereby, urge balls 110
longitudinally toward the proximal end of the case and inward
toward the case axis. Surface 103a prevents recessing. However,
when this reaction force overcomes the bias of spring 113, sleeve
112 retracts proximally so that balls 110 move along surfaces 103a.
At junction of 103a and 103b along longitudinal movement the in
proximal direction, the balls can and do recede toward case axis
along surface 103b. The balls become fully recessed when contacting
103c and, consequently, have no forces driving them further toward
the axis. Coincidentally, the balls contact surfaces 101d and 103d
preventing further longitudinal travel. As shown in the figures,
cooperative structures are provided to prevent travel; FIGS. 13, 14
& 17 depict the component positions when balls 110 are fully
retracted, which enables free passage through an aperture.
[0103] Upon exiting the aperture, the bias of spring 113 and
absence of outside forces allows the balls 110 to reverse the ravel
sequence described above and return to lowest energy position
described in FIG. 6.
[0104] Pulling the lock back out of an aperture in the locked state
is resisted by surfaces 101c of slot 130 and 103a of rotor 103.
Consequently, the locked lock allows entry into an aperture but
prevents extraction without unlocking in view of the cooperative
configuration and relationship of the locking apparatus
components.
[0105] Other nonlimiting embodiments as well are contemplated
within the present invention. Some possible alternate nonlimiting
embodiments include the following, but are not considered
exhaustive. In one example embodiment, the compression spring 113
and sleeve 112 could be replaced and in many ways with various
structures or different types of materials (flexible plastics,
metals, resilient materials, or other suitable materials). For
instance, a variable pitch spring could eliminate the need for
sleeve 112. Or a leaf spring could be incorporated into the rotor
stem 113 so that the rotor stem could perform requisite functions
of sleeve 112, spring 113 and rotor stem 113. In another example
embodiment, a leaf spring or other biasing mechanism could be
incorporated in a sleeve 112. In another example embodiment, an
independent compression spring for each ball 110 could be used. In
another example embodiment, the biasing arrangement could be
provided by an extension or leaf spring pulling the sleeve toward
the distal end of the rotor stem. Other example embodiments, can
include a single or multiple ball bearings 10 or other components
such as, for example, a leaf spring, urethane spring, o-ring.
[0106] Referring generally to FIGS. 21-30, example embodiments of
the present invention are illustrated. In various example
embodiments, the barrel lock may be used with a variety of types of
hardware adapted to receive a barrel lock so as to secure a given
locking device and may used secure a numerous other types of
locking devices or hardware.
[0107] In an example embodiment of the invention, the barrel lock
is adapted for use with various types of hardware capable of
receiving a barrel lock as noted. In one example embodiment, the
barrel lock comprises a body, at least one locking member and a
biasing member for biasing the locking member into an extended
mode. In other example embodiments, a plurality of locking members
are provided. When a sufficient external force is applied to the at
least one locking member, the locking member moves into a retracted
mode, such that at least a portion of the locking member is
retracted into the body and such that the barrel lock may be
inserted into the hardware (Hardware may be any of various types of
structure or devices adapted for receiving a barrel lock. The
barrel lock is axially insertable in example embodiments as noted
herein).
[0108] The following provides a description of an example
embodiment of the locking apparatus. The motion of locking members
(or ball bearings 210), in this example embodiment, will be
described longitudinally along the axis of case 201 as proximal and
distal relative to end cap 202; the motion of balls 210 will also
be described radially relative to center axis of case 201. Also, in
this example embodiment, to "recess", "recede" or "retract" shall
refer to travelling toward the case 1 axis and to "extend" shall
refer to travelling away from the case 201 axis.
[0109] Referring to FIGS. 21 and 22, the locking assembly is shown
with ball bearings 210 extended from inside case 201 through slots
230 on opposing sides of case. Ball position boundaries are
partially defined by the following elements of case 201: 201a,
201b, and slot 230 ends 201c and 201d. Retaining protuberances 201a
and 201b restrain the balls within the lock assembly and present a
physical boundary within which balls can recede toward or extend
from the case center axis in an example embodiment. The ball
bearings (e.g., 210) track within the respective slots
longitudinally parallel with the case center axis and are bound by
slot 230 ends 201c and 201d.
[0110] The positioning of balls 210 is further constrained by the
geometry of plunger stem 3. Referring to FIG. 28, plunger stem 203
has four surfaces (203a, 203b, 203c, and 203d) controlling the
position and movement (and behavior) of balls 10. Surface 3c
defines the boundary of recessing travel of the balls 210 so that
the balls can recede toward access no further than surface 203c.
Surface 203d in cooperation with surface 201d of slot 230 defines
the boundary of proximal longitudinal travel of ball 210. Surface
203a presents a hard bearing surface and interference with the ball
movement that prevents the balls from recessing.
[0111] Referring to FIG. 26, the balls 210 are shown at the most
extended state. The balls are constrained by surface 203a, surface
201c of slot 230 and retaining protuberances 201a and 201b. At this
most extended state, the spherical center of balls 210 remains
within the lock case 201. Consequently, any effort to push the lock
into and through an aperture would generate (or render) forces both
proximally longitudinal and radial toward center.
[0112] Referring to FIGS. 26 and 29, sleeve 212 and compression
spring 213 cooperatively biases balls 210 toward surface 201c of
slot 230. Sleeve 212 bears on balls 210. Compression spring 213
permits translation of the sleeve along the case axis and biases
toward a rest position at the most extended position or state as
described in FIGS. 21, 22 and 26.
[0113] When the keyless insertion lock is pushed into an aperture,
resistance (or reaction forces) from the surfaces or walls creating
the aperture, push against balls 210 and, thereby, urge balls 210
longitudinally toward the proximal end of the case and inward
toward the case axis. Surface 203a prevents recessing. However,
when this reaction force overcomes the bias of spring 213, sleeve
212 retracts proximally so that balls 210 move along surfaces 203a.
At junction of 203a and 203b along longitudinal movement the in
proximal direction, the balls can and do recede toward case axis
along surface 203b. The balls become fully recessed when contacting
3c and, consequently, have no forces driving them further toward
the axis. Coincidentally, the balls contact surfaces 201d and 203d
preventing further longitudinal travel. As shown in the figures,
cooperative structures are provided to prevent travel; FIGS. 23, 24
& 27 depict the component positions when balls 210 are fully
retracted, which enables free passage through an aperture.
[0114] Upon exiting the aperture, the bias of spring 213 and
absence of outside forces allows the balls 210 to reverse the ravel
sequence described above and return to lowest energy position
described in FIG. 26.
[0115] Pulling the lock back out of an aperture in the locked state
is resisted by surfaces 201c of slot 230 and 203a of plunger stem
203. Consequently, the locked lock allows entry into an aperture
but prevents extraction without unlocking in view of the
cooperative configuration and relationship of the locking apparatus
components.
[0116] Other nonlimiting embodiments as well are contemplated
within the present invention. Some possible alternate nonlimiting
embodiments include the following, but are not considered
exhaustive. In one example embodiment, the compression spring 213
and sleeve 212 could be replaced and in many ways with various
structures or different types of materials (flexible plastics,
metals, resilient materials, or other suitable materials). For
instance, a variable pitch spring could eliminate the need for
sleeve 212. Or a leaf spring could be incorporated into the plunger
stem 203 so that the plunger stem could perform requisite functions
of sleeve 212, spring 213 and plunger stem 203. In another example
embodiment, a leaf spring or other biasing mechanism could be
incorporated in a sleeve 212. In another example embodiment, an
independent compression spring for each ball 210 could be used. In
another example embodiment, the biasing arrangement could be
provided by an extension or leaf spring pulling the sleeve toward
the distal end of the plunger stem. Other example embodiments, can
include a single or multiple ball bearings 210 or other components
such as, for example, a leaf spring, urethane spring, o-ring.
[0117] Referring to FIGS. 8b, 18b and 28 c, and regarding the
uni-directional, one way pass through features, anti-retraction
interface geometry, in non-limiting example embodiments, the
geometry of rotor stems 3, 103 and plunger stem 203 defines the
one-way-pass-through behavior of the ball bearings during keyless
insertion that enables uni-directional travel of ball bearings and
anti-retraction of lock. When in the locked state surface a resists
the balls from receding into the case and ensures anti-retraction
of lock. When lock is pushed into a stationary aperture of
sufficient size to allow entry of case while contacting ball
bearings and with sufficient force to overcome biasing means, the
reactionary forces of the aperture wall push the balls proximally
toward surface d. Because the geometric center of the ball bearing
remains always within the case, the aperture walls exerts a
reaction force to the balls that is necessarily tangential; thus,
the balls are also pushed inward toward the center axis of rotor
stem. As the lock enters the aperture in a keyless operation, the
balls travel proximally along surface a until reaching surface b
when it also begins to descend along a slope defined by angle
.beta.. Angle .beta. is 45 degrees in this embodiment and could
vary significantly and remain operable but would require changes to
other components. The smaller the angle the longer slot 30, 130 and
230 must become and shorter is preferable for multiple reasons:
strength of case body reduces as hole increases in size, the
biasing mechanism must accommodate longer travel which may cause
complications and importantly the lock shaft would have to increase
in length which would make it incompatible with existing locking
devices. Angle .beta. could increase by 20 degrees and function,
but the rotor stem would be weaker and the lock assembly would
require a stronger biasing means to push the balls up the steeper
slope. As the lock continues to enter the aperture in a keyless
operation, the balls travel down slope b until reaching surface c,
where the ball is fully recessed within the case at which point it
is also in contact with surface d defined by angle .alpha.. Angle
.alpha. is 45 degrees in this embodiment and could vary
significantly and remain operable, but would require changes to
other components. A larger a would require extending the length of
surface c and would weaken the rotor stem. A smaller a would not
require any change but would also offer no benefit.
[0118] Note that each of the following, as well as the foregoing,
provide non-limiting example embodiments or the invention: The
following discussion describes alternate embodiments of the means
of urging the balls into the locked position and allowing the balls
to recede into the case during a keyless insertion. The FIGS. 1-30
describe example embodiments, and further, non-limiting example
embodiments are provided as follows, as indicated. Variations of
the following can be applied to each example embodiment or
alternatives.
[0119] Another example embodiment below refers to the following
figures: FIG. 31 is a perspective view of a keyless insertion lock
with partial section cut-away showing alternate biasing means leaf
spring 401 and rotor stem 3'; FIG. 32 is a perspective view of
rotor stem 3' with biasing means 401 and ball bearings 10; FIG. 33
is a perspective view of rotor stem 3' with biasing means 401; FIG.
34 is a perspective view of biasing means 401; FIG. 35 is another
perspective view of biasing means 401. As illustrated, a stamped
leaf spring design is provided wherein the keyless insertion lock
replaces a biasing means provided by bushing 12 or 112 and spring
13 or 113 with a single leaf spring 401. Component 401 as presented
is formed from flat stock spring stainless steel. In other
embodiments, the component could also be formed from spring wire.
Different materials with sufficient elasticity could be used. The
simple design of this spring offers economic opportunity in the
price sensitive market of the product. The base band 405 attaches
to the rotor stem. An embossment on the case interferes with
rotational movement about longitudinal axis of rotor stem and case
to ensure positional alignment with slots 30. When balls are forced
into recess during keyless insertion, the leaf springs deflect to
allow necessary travel of balls along path defined by rotor stem
and case as described above. Rotor stem 3' is an alternate
embodiment of rotor stem 3 or 13 that is modified to provide
movement space for deflecting spring. The shape of deflecting
members 402 and 403 defined by angels .delta. and .theta. provides
the necessary biasing both distally and outwardly. These angels can
range from 20 to 60 degrees. The angles and the position of the
bend defined by variable "d" are interdependent. Multiple variable
value combinations will provide effective forceful contact to ball
bearings that will bias ball bearings to locked position while
enabling recess and travel necessary for keyless insertion.
[0120] Another example embodiment below refers to the following
figures: FIG. 36 is a perspective view of a barrel lock in the
locked condition in accordance with multiple embodiments of the
present invention. In this view, the locked assembly balls 10 are
extended with biasing means 501 visible through slot 30 in case 1.
FIG. 37 is a perspective view of of rotor stem 3'' of keyless
insertion barrel lock with biasing means 501 and ball bearings 10
in the locked position. FIG. 38 is a perspective view of the rotor
stem 3'' of keyless insertion barrel lock with biasing means. FIG.
39 is a perspective view of the distal end of rotor stem 3'' of
keyless insertion barrel lock. FIG. 40 is a sectional perspective
view of the distal end of rotor stem 3'' of keyless insertion
barrel lock. FIG. 41 is a perspective view of biasing means 501. As
illustrated, a wire leaf spring design is provided wherein a
keyless insertion lock replaces biasing means provided by bushing
12 or 112 and spring 13 or 113 with a single leaf spring 501. In
this embodiment, 501 is a formed spring wire; however, a functional
equivalent could be formed from flat steel stock. In both cases,
the component 501 is made of stainless spring steel though other
material could be used. The simple design of this spring offers
economic opportunity in the price sensitive market of the product.
In the locked state, the ball bearings 10 are baised by segment 504
to the extended and distal position within slot 30. During keyless
insertion the ball bearings 10 are fully recessed and move
proximally within the lock case 1, the leaf spring 501 is
compressed into the rotor stem 3'' reliefs 502 to allow full travel
of the balls 10. In the compressed state, the deflecting ends 504
move into recess that ends at 503. Recess 502 also holds the
biasing means in proper orientation relative to rotor stem 3''. The
members 505 are formed to remain within 502 and deliver holding
force to retain position and attachment to rotor stem 3''. Member
506 in cooperation with the distal end of rotor stem 3'' prevents
longitudinal travel of 501 in the proximal direction along the
rotor stem 3''. Angle .chi. is 45 degrees in this embodiment but
could be implemented in a range of 15 to 75 degrees.
[0121] Another example embodiment below refers to the following
figures: FIG. 42 is a perspective view of distal end of a barrel
lock in the locked condition in accordance with multiple
embodiments of the present invention. In this view, the locked
assembly balls 10 are extended with bushing 12' visible through
slot 30 in case 1.
[0122] FIG. 43 is a perspective view of rotor stem of keyless
insertion barrel lock with biasing means and ball bearings in the
locked position.
[0123] FIG. 44 is a perspective view of the rotor stem of keyless
insertion barrel lock with biasing means. As illustrated, a cupped
bushing design is provided wherein a bushing 12' is an alternate
embodiment of bushing 12, 112 and 209 and performs the same
functions. The cupped reliefs 601 in bushing 12' encompasses the
ball bearings 10, 110 and 210. The shape of the relief matches the
radius of the ball bearings plus some clearance to allow a slip fit
to permit the ball to actuate within case 1, 101 or 201 and rotor
stem 3 or rotor stem 103 or plunger stem 203. Bushing 12' shrouds
access to internal mechanics of the lock when the cupped relief 601
mates with the ball bearings. The benefits include improving
reliability by reducing the possibility of debris entering the
lock, which may hamper operation of keyless insertion or keyed
operation. Another potential benefit is reducing access to internal
components of lock, which inhibits nefarious tampering efforts to
disable or retard proper lock functions.
[0124] Regarding another example embodiment including at least a
pivot plunger, and referring also to FIGS. 45-51 generally, in one
alternative embodiment of invention is to replace ball bearings
with a toggle. In the presented embodiment toggles are urged into
the locked position by a biasing means as described in FIGS. 21-30.
The plunger stem 603 supports and positions a pivot pin 612. The
toggles also have through holes that mate with the pivot pin 612. A
slot at the distal end of plunger stem 603 accommodates the toggles
that are free to move within slot 230 while urged to the locked
position by biasing means. When the lock is inserted into an
aperture, the toggles pivot upon the pin to recede with case 201.
Regarding another example embodiment including at least a pivot cut
slot, and referring also to FIGS. 45-51 generally, in one
alternative embodiment cases 1, 101, and 201 provide an opening 30,
130 and 230 in which ball bearings articulate to enable keyless
insertion of the lock. The opening can be manufactured in multiple
ways. One alternative embodiment is case 701 is a sloped angle on
the proximal end of the slot to produce surface 701d. Surface 701c
is normal to axis of case and rotor stem. One possible method of
producing the opening is milling a hole and pivoting the part
relative to the cutting mill. A benefit of the sloped geometry is a
reduced opening. A reduced opening minimizes the necessary length
of the ball retaining features 701a and 701b. Additionally, a
smaller opening inhibits entry of debris into the lock, which may
impair proper functioning or frustrate attempts to defeat proper
operation. The sloped geometry may improve product reliability by
improving ruggedness when lock is abused or aggressively inserted
into an ill-fitting receptacle. The slope in this embodiment
matches that of the ball path defined by the rotor stem, which is
45 degrees.
[0125] Another example embodiment below refers to the following
figures: FIG. 52 is a perspective view of locking pin in the locked
condition. FIG. 53 is a sectional view of locking pin in the locked
condition. FIG. 54 is a sectional view of locking pin in the
unlocked condition. FIG. 55 is a sectional view of locking pin with
biasing members displaced and ball bearings recessed within case.
FIGS. 52-55 generally, apply to a locking pin, often called "quick
release pins," which typically require manually pushing a button to
actuate a locking member holding the ball bearings from the lock
position to allow the balls to recede into the pin body for either
insertion or extraction from a receptacle. This invention enable
insertion without manually actuating a locking member, but does
require actuation of locking member for extraction. Referencing
FIG. 52, pin body 801 and handle 802 and ball bearings 804
resembles typical quick release pin. The locking member 803
translates along axis defined by case 801. The end of locking
member 803 protruding from handle 802 is pushed by an operator to
manually unlock the pin by translating locking member recesses into
alignment with ball bearings 804. FIG. 53 shows assembly in the
locked condition and FIG. 54 shows the assembly in the unlocked
position. Biasing means 805 causes the lock to be in the locked
position without forceful actuation. The ball bearing 804 are held
in position relative to locking member by biasing members spring
808 and bushing 807. When pin is inserted into a receptacle without
actuating locking member, the balls are pushed by reaction forces
from receptacle toward handle along axis of pin body 801 and inward
to enter into locking member 803 recess.
[0126] Another example embodiment below refers to the following
figures: FIG. 56 is a perspective view of lock in the locked
condition with rotor stem in the locked position. FIG. 57 is a
sectional view of lock in the locked condition with rotor stem in
the locked position. FIG. 58 is a sectional view of lock with rotor
stem in the locked position and toggles receded during keyless
insertion. FIG. 59 is a sectional view of lock in the unlocked
condition with rotor stem in the unlocked position. FIG. 60 is an
isometric view of the rotor stem. FIG. 61 is an isometric view of
the toggle (Note items 1000 series. Case 1001, Case pivot holes
1002, Case slot 1003, Toggles 1010, Toggle holes 1011, Toggle cam
surface 1007, Bushing 1012, Spring 1013, Rotor Stem 1004, Rotor
Stem cam surface 1005, Pivot pin 1006). This embodiment of the
invention utilizes toggles 1010 in a rotary lock instead of ball
bearings. The toggles 1010 rotates about a pivot pin 1006 and
within slot 1003 of case 1001. The toggles 1010 recede into housing
during keyless insertion and recover into locked extended position
after passing through receiver aperture by urging from a biasing
means provided by bushing 1012 and spring 1013. The pivot pin 1006
passes through holes 1002 and 1011 in the lock case 1001 and
toggles 1010. A rotating rotor stem 1004 pushes the toggles 1010
into an unlocked receded position when turned about axis defined by
case 1001. The actuation of the toggles 1010 by rotor stem 1004 is
caused by a cam surface on the rotor stem 1005 bearing against
toggle surface 1007. When the rotor stem 1004 is turned to the
locked position, contact between surfaces 1007 and 1005 is absent
and the toggles freely return to locked position by urging of
biasing means.
[0127] While the present invention has been shown in example
embodiments comprising disk tumbler barrel locks, it may also be
used in many other types of barrel locks as well as retaining pins
and other devices where retractable retaining members would be
useful.
[0128] A further description, and in some instances a summary
outline, is provided identifying various aspects of example
embodiments in conjunction with FIGS. 1-62, as applicable, and
related descriptions with regard to various views of embodiments
including certain members, components, structures, and
configurations in accord with possible embodiments of the
invention. It should be recognized that regarding cost issues, in
an example embodiment, the present invention addresses: the speed
of installation, in that the lock is field installable without a
key or other tool and may be pushed in to install, with a
uni-directional ball release; a lower cost labor pool, in that
there is less concern over worker honesty (i.e., in view of the
above, as noted, the lock is field installable without a key or
other tool and may be pushed in to install, with a uni-directional
ball release); the lower skill requirement in regards to simple
operation (i.e., in view of the above, push in to install, with a
uni-directional ball release (referred to herein as a "pushed in to
install" aspect)): less training, again, in view of the simple
operation (i.e., "pushed in to install"), and as noted, again, the
lock is field installable without a key or other tool and may be
pushed in to install, with a uni-directional ball release; no key
tracking required for installers (i.e., again, in view of the
above, as noted, the lock is field installable without a key or
other tool and may be pushed in to install, with a uni-directional
ball release); cannot be locked inadvertently (it can be inserted
through multiple locking layers (with a uni-directional ball
release)).
[0129] In addition, it should be recognized that regarding cost
issues, in an example embodiment, the present invention addresses
manufacturing costs related to: simpler components being required
(i.e., simpler spring), simpler assembly (fewer components) in that
components drop in place (i.e., no rotation orientation required,
no special fixtures, no special tools) and in that the lock does
not have to be shipped in an opened orientation.
[0130] It should be further recognized that regarding reliability
issues, in an example embodiment, the present invention provides:
better assurance that the lock is properly installed in that
audible or tactile feedback informs the user when the lock is
installed correctly (e.g., audible click, tactile click) and in
that the lock can be fully inserted to a proper locking position
without locking in the wrong position; self locking in that the
locking members are biased to a locking position with the
uni-directional ball release feature; the lock is not subject to
pre-mature locking before installation (i.e., in view of the
uni-directional ball release); a reduced tolerance requirement
regarding the position of the locking ball engagement with the
rotor stem, in that the holding surface engagement created for
engagement with balls is larger and the balls are allowed to travel
in an axial direction to enter the notch in the rotor stem and
further that the ball hole is obround; the rotor stem is better
located in the shaft of lock (e.g., sleeve centralizes rotor stem);
elimination of ball sticking in locked position.
[0131] In addition, it should be recognized that regarding ease of
use, in an example embodiment, the present invention fosters user
friendliness in that: the lock can be installed easily with gloves
(e.g., "pushed in to install" feature); an audible or tactile
feedback informs the user when the lock is installed correctly
(e.g., audible click, tactile click); it is simple to operate and
provides one-handed installation (i.e., in view of the above, as
noted, pushed in to install, with a uni-directional ball
release).
[0132] It should also be recognized that regarding application
specific performance, in an example embodiment, the present
invention fosters better security in that; there is better key
control; the lock is field installable without a key or other tool
(i.e., in view of the above, as noted, pushed in to install, with a
uni-directional ball release); the lock can be used in many
different types of hardware and in many types of barrel locks; the
lock provide tamper resistance.
[0133] Additionally, it will also be appreciated that various
problems were recognized and resolved to reach a workable design
related to: shaping the rotor stem to receive and hold the locking
balls; the angle of the notches on the rotor stem; balancing
abruptness with the length on the entry side of the notch and
coordinating and configuring the angle to be tangent with the ball
when retracted and at the upper limit of the obround slot;
captivation of balls; shaping of the ball hole opening; smoothness
of insertion involving better location of the rotor stem in the
shaft of the lock (e.g., sleeve centralizes rotor stem) and
allowing the locking balls to travel in the axial direction to
enter the notch in the rotor stem (with the obround ball hole);
choosing spring forces to balance extension of the balls with
resistance to insertion.
[0134] It should be noted that in an example embodiment, the
invention includes at least the following components: case (or
rotor-lock case); rotor (or rotor-lock rotor); rotor stem (or
rotor-lock stem); top tumbler; fence; base guard; spacer; code
tumbler; end cap; ball bearing; weather seal (SI, rubber); sleeve
or bushing (which is adapted to bear on locking balls to bias
expansion); spring (compressed-uncompressed); sampler receiver. It
should be noted that in another example embodiment related to a
plunger lock configuration, the invention includes at least the
following components: plunger case; plunger cap; plunger stem;
plunger decoy; plunger lock spring; weather seal, SI, rubber;
o-ring; plunger snap spring; plunger bushing; BB; sampler receiver.
It should be noted that in example embodiments, the invention
provides various configurations related to and including at least:
case is upset, ball retaining, left; case is upset, ball retaining,
right; case, slot, proximal end; case, slot, distal; case, slot;
rotor stem, notch angle, proximal; rotor stem, distal. It should
also be noted that in other example embodiments, the invention
provides alternates such as a: leaf spring, alternate biasing
means; proximal bend member; distal bend member; extension (leaf)
member; band; proximal angle; distal angle; wire leaf spring,
alternate biasing means; rotor stem relief pocket; rotor stem
relief pocket, end; wire leaf spring, deflecting member; wire leaf
spring, vertical member; wire leaf spring, horizontal end member;
angle of deflecting member; cupped recess in alternate bushing;
toggles; alternate plunger stem; toggle pivot pin; case; handle;
