Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation-in-part of application
Ser. No. 10/853,451, filed May 25, 2004.
[0002] The instant application claims priority to the
above-referenced application. All written material, figures,
content and other disclosure in the above-referenced application is
hereby incorporated by reference.
BACKGROUND OF THE INVENTION
[0003] 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
various 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.
[0004] For example, one known watthour meter socket consists of a
meter box having two sets of electrical connections, with a
provider's transmission lines being connected to one set of
connections, and the customer's service lines to the other set. To
establish a circuit and measure the amount of electricity a
customer uses, the socket box is configured to accept a watthour
meter, or another electricity usage measurement device, which, when
plugged into the socket, permits transmission of electricity from
the provider to the customer and allows the amount of transmitted
electricity to be measured in watthours, so that the provider can
charge the customer for power usage at an appropriate rate.
[0005] Various designs and uses for watthour meters are also well
known, and all such designs and uses are incorporated into the
teachings of the present invention. The present invention is also
applicable in situations where the customer's electrical service
lines are routed from the socket box to a breaker box, so that
electricity can be distributed to various other service locations
using additional sets of power lines or wires.
[0006] There are several known types of socket meter boxes, each
being distinguished by the method in which the meter is secured in
place once it has been plugged into the socket. For example, there
is a ringless type meter box, which typically includes a meter box,
an installed meter, and a box cover. A flange is formed around a
meter head passage space disposed in a central portion of the box
cover. A complementary flange is disposed on the meter base, so
that the complementary flange sections join together when the meter
head passage space is placed over and around the meter head. The
meter box cover is then secured using a security device, for
example, a small latch assembly or the like, disposed on the box
cover, which functions in structural cooperation with a
complementary latch-receiving member disposed on the meter box,
thereby ensuring that the meter cannot be easily removed without
first removing the cover after installation is complete.
[0007] As seen in FIG. 1, a ringed socket meter box 5 is also
known, which typically includes a box cover flange 10 formed around
a meter head passage space 12 cut out of a central portion of box
cover 20. Meters used in conjunction with a ringed type socket
meter box 5 are designed to interface with box cover flange 10 by
means of a complementary mounting flange 40 disposed on the meter
base, forming a watthour meter and meter box cover flange
combination. The meter flange is then secured to the box flange by
means of an annular, lockable sealing ring 50. The ring sealed
meter socket box is designed such that, once a meter is plugged
into the socket and the box cover is installed over the meter head,
the meter cannot easily be removed without first removing the
sealing ring. The box cover secures the meter to the electrical
socket so that completion of an electrical circuit is ensured and
reliably prevents the meter from falling out of the socket.
[0008] The box cover also prevents unauthorized persons from
tampering with an installed meter. For example, some customers have
attempted to bypass the meter, so that unmeasured electricity could
be used free of charge. Also, service providers are sometimes
forced to disconnect service to customers, for example, due to
non-payment of monthly bills. In this event, the box cover keeps a
customer from entering the socket box and reconnecting electrical
service. However, in instances where a small latch assembly on the
box fails to provide sufficient security for the meter and socket
box, a sturdier, more tamper resistant solution is required.
[0009] In FIG. 2, a known lockable sealing ring is depicted in
which an annular locking band 60 is divided so as to form two
terminus portions 61, 62. In practice, locking band 60 is wrapped
around the meter and box cover flange combination after the meter
has been installed into an electrical socket disposed in the meter
box. A diameter measured between interior surfaces of the band will
vary depending on whether terminus portions 61, 62 are loosely
disposed or drawn together.
[0010] Once terminus portions 61, 62 have been drawn together, a
locking mechanism 70 is attached so that terminus portions 61, 62
are securely held. A fastener 75 is aligned with a captured nut 80,
and then rotatably threaded into a receiving portion of captured
nut 80. Installation of fastener 75 is usually completed using a
screwdriver or another hand tool. As fastener 75 is progressively
threaded into captured nut 80, terminus portions 61 and 62 are
drawn together until the band is tightly wrapped around a
circumference of the meter and box flange combination, thereby
securing the meter in place within the box.
[0011] There are other known sealing ring housing and fastener
configurations. For example, a box-sealing ring is disclosed in
U.S. Pat. No. 5,851,038, in which a pair of sealing ring housings
is disposed on opposite ends of an annular band. Bendable mounting
tabs are extended from each of the ring housings into slots
disposed in the band. A threaded fastener extends through a first
threaded aperture disposed in one housing, and then through a
second threaded aperture disposed in an opposite housing. An
enlarged fastener head enables the installer to hand thread the
fastener through each of the apertures during initial phases of
installation. Fully threaded installation of the fastener is
effected by inserting a screwdriver into receiving slots formed in
each end of the fasteners and then rotating the screwdriver.
[0012] An axial slot cut in one end of the fastener is aligned with
an aperture provided in the walls of the opposite housing member to
permit attachment of a security device. Known methods of attaching
the housings to the band include riveting the housings onto the
ring, combining rivets with tabs to affix the housings to the band,
and welding the housing to the ring.
[0013] In view of the foregoing, it is apparent there exists a
strong need for an inexpensive and effective means by which a
watthour meter can be reliably secured to a socket box cover. There
is also a need for a meter box cover locking device that is simple
in design, requires a reduced number of parts, and permits an
installer to quickly, safely and effectively install the device in
some cases without the use of tools.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
[0051] Turning now to the drawings, the attached figures illustrate
an apparatus for securing a plurality of structures. For example,
in one embodiment, the apparatus is used for securing a watthour
meter to a socket box. The apparatus may also be used for creating
a tamper-evident seal or as a locking assembly with at least one
structure as will hereinafter be explained in further detail.
[0052] According to a specific, non-limiting embodiment of the
invention, and referring now to FIG. 3a, an apparatus for securing
a watthour electrical meter to a socket box cover comprises an
annular band 100, a body portion of which is divided to comprise
opposed tab members 176, 178. In certain embodiments, an interior
diameter 130 of annular band 100 is selected to fit around a
watthour meter and socket box flange combination in accord with
industry standards, for example, in accord with the industrial
standard for watthour meters set by the American National Standards
Institute ("ANSI"). In other embodiments, however, an interior
diameter 130 of annular band 100 is selected to secure electrical
meters of non-standard or proprietary sizes that do not meet the
ANSI industrial standards for watthour meters.
[0053] According to one example embodiment, annular band 100 is
formed from a metallic material. In another embodiment, the band is
extruded from a metal strip. In a further embodiment, the band
material is rolled into the shape of an annular band. In a still
further embodiment, the band is extruded from a solid rod. In other
embodiments, annular band 100 is formed from a composite material,
for example, from a hardened resin. In still other embodiments,
annular band 100 is formed from plastic.
[0054] According to other aspects of the invention, apertures are
formed in either one or both of the band's tab members to support
installation of a ring fastening means. Forming apertures in the
tab members is achieved in various embodiments by drilling,
stamping, cutting or burning techniques, or using any other
acceptable fabrication method available to one of ordinary skill in
the art. In an alternative embodiment, only one ring tab member has
an aperture portion formed therethrough, the other tab member
comprising a complementary housing and nut assembly; in a further
embodiment, the second tab member comprises a housing member for
housing a rotatably secure fastener assembly.
[0055] Referring now to FIG. 3b, an isometric view of the apparatus
for securing a watthour meter to a socket box shown in FIG. 3a is
shown. Disposed through body portions of locking tab members 176,
178 are opposed, substantially circular apertures 130, 140; opposed
tab member terminus portions 110, 120 are also provided. Each of
apertures 110-140 support installation of numerous ring fastener
and fastener receiver assemblies, as is discussed in greater detail
below.
[0056] Tab members 176, 178 also perform multiple functions. For
example, in some embodiments, tab members 176, 178 comprise support
structures for fastener combinations used to draw terminus portions
110, 120 tightly together. In other embodiments, tab members 176,
178 are used as grasping points by installers during assembly, and
permit terminus portions 110, 120 to be drawn tightly together so
that a fastener and receiver combination can be engaged. Once tab
member terminus portions 110, 120 are tightly drawn and tab members
176, 178 are locked together, any subsequent attempt to tamper with
the installed ring fastener and receiver assembly is significantly
hindered.
[0057] Referring now to FIG. 3c, an alternative embodiment is shown
wherein a plurality of apertures 130-160 is formed in body portions
of each of tab members 176, 178. In one example embodiment,
apertures 130, 140 are substantially circular in shape, and permit
a cylindrical ring fastener and fastener receiver combination to be
attached. In another embodiment, apertures 150, 160 are
substantially ovoid in shape, and are suitable for receiving any
known fastening device that will fit within the confines of the
apertures. It should be noted, however, that virtually any size or
number of apertures of any shape can be employed, provided that
reciprocal pairs of apertures are disposed on the tab members 176,
178 so that a fastening means can be reliably installed through
each of the apertures prior to completion of installation.
[0058] In further embodiments, a wire seal is inserted through each
of circular apertures 130, 140 in order to secure the tab members
176, 178 together. In still further embodiments, only apertures 150
and 160 are present, and a wire seal or a mechanical locking
mechanism is used to hold the tab members together. In further
embodiments still, tab members 176, 178 are secured by means of a
mechanical lock, such as a padlock, a fastening end of which is
inserted through each of two opposing apertures and then fastened
into a body portion of the lock.
[0059] FIG. 4a illustrates an example embodiment of the invention
where annular band 170 further comprises a pair of opposed tab
members 176, 178, each having a circular aperture formed in a body
portion through which ring fastener 180 and fastener receiver 190
have been installed. In some embodiments, ovoid apertures 192 and
194 are included so that a wire seal ring or a mechanical lock can
also be attached.
[0060] In FIG. 4b, a close up view of ring fastener 180 is
provided, wherein fastener 180 is installed through an aperture
formed in a body portion of tab member 178. Ring fastener 180 has a
gripping member 200 disposed at one end, and a threaded shaft 220
and ring fastener aperture 210 disposed at an opposite end. In
certain embodiments, there is more than one ring fastener aperture
210 formed through ring fastener 180 at various axial locations
around the ring fastener. In a presently preferred embodiment, a
support shelf 230 rotatably supports ring fastener 180 after it has
been passed through the aperture formed in tab member 178. In the
embodiment depicted in FIG. 4b, gripping member 200 comprises a
substantially cylindrical body, and includes a gripping surface
that permits an installer to easily grasp and rotate the gripping
member 200 during installation.
[0061] FIG. 4c is a close up view of fastener receiver 190 disposed
in an aperture formed through a body portion of tab member 176. In
some embodiments, a fastener aperture 192 is formed in a body
portion of the fastener receiver 190. In other embodiments,
fastener receiver 190 has a pair of opposed fastener apertures 202,
208 disposed at one end, and a threaded receiving portion 206 and a
support member 204 combination disposed at an opposite end. Opposed
apertures 202, 208 are disposed such that single a standard wire
seal may be inserted through both apertures during installation. In
other embodiments, a fastening member of a padlock or another
mechanical lock is inserted through apertures 202, 208 and then
secured by a locking mechanism disposed in a body portion of the
lock.
[0062] In various other embodiments, apertures 202, 208 are
disposed at other axial locations on the receiving member, and not
necessarily the opposed axial locations shown in FIG. 4c. In
further embodiments, there is only one aperture 202 formed through
a body portion of fastener receiver 190. In still further
embodiments, there are more than two apertures disposed formed
through a body portion of fastener receiver 190, while in other
embodiments, a plurality of opposed pairs of apertures is disposed
at various other axial locations disposed around the body of
fastener receiver 190.
[0063] Returning to FIG. 4a for a moment, a method of securing a
watthour meter to a socket box is provided, wherein an installer
grasps outer surfaces of tab members 176 and 178, and draws tab
member terminus portions 172, 174 tightly together. After ring
fastener 180 is aligned with an aperture formed through a body
portion of tab member 178, a threaded shaft portion of ring
fastener 180 is threaded through the aperture and into a threaded
receiving portion of fastener receiver 190. After the ring fastener
shaft is fully threaded into a body portion of fastener receiver
190, fastener 180 is finally tightened by means of a wheel knob
rotated at the head of the fastener. In various other embodiments,
an installer achieves final installation by tightening the ring
fastener with a hand tool, such as a screwdriver or a ratchet.
[0064] FIG. 5a is a plan view of the locking ring shown in FIG. 4a,
in which opposed tab members are shown drawn together by means of
an installed ring fastener 180 and fastener receiver 190 assembly.
FIG. 5b is a close up view of the ring fastener 180 and fastener
receiver 190 shown in FIG. 5a, in which terminus edge portions 172,
174 of opposed tab members 176, 178 are tightly drawn so as to
hinder unauthorized tampering with the ring fastener 180 and
fastener receiver 190 after installation is complete.
[0065] According to further aspects of the invention, and referring
now to FIG. 6a, a ring fastener is provided comprising a gripping
member 250, a support member 260, a threaded shaft 270, and a body
portion 280 having a fastener aperture 282 formed therethrough.
Gripping member 250 is used to thread and rotate the ring fastener
during installation. Threaded shaft 270 is used to thread the
fastener into a receiving member (not shown), and fastener aperture
282 is sized to accept a known metal sealing wire. In other
embodiments, fastener aperture 282 is sized to receive a fastening
portion of a padlock or other mechanical lock. FIG. 6b shows the
ring fastener of FIG. 6a when rotated ninety degrees so that body
portion 280 is viewed on edge.
[0066] In one embodiment, support member 260 has an outer
circumference that is smaller than an inner circumference of the
aperture through which it is to be installed; in this embodiment,
the head of gripping member 250 is also larger than a circumference
of the aperture. In various other embodiments, support shelf 260
has a circumference of about the same size as the circumference of
gripping member 250.
[0067] In certain embodiments, the gripping member is formed
structurally integral with a ring fastener shaft member. However,
in alternative embodiments, the gripping member is formed
separately from the ring fastener shaft member and then attached to
the shaft member using known attachment methods, for example, by
gluing or welding the gripping member to a head portion of the
shaft member, or by threading a threaded portion of the shaft
member head into a thread receiving portion cut into an interior
portion of the gripping member.
[0068] FIGS. 6c-6e show various other embodiments of the ring
fastener 250, in which various other apertures, threading and
support member features are depicted. For example, in the
embodiment depicted in FIG. 6c, ring fastener 250 further comprises
a support shelf 260, and a fastener aperture 284 disposed within a
threaded shaft portion 272 of ring fastener 250. In the example
embodiment of FIG. 6d, a portion of the support shelf terminates in
a recessed groove 262, around which a retaining member 264 (see
FIG. 6e) is placed so that one or more tab members 265a-c fit down
within the recessed groove to further inhibit removal of the ring
fastener.
[0069] According to further aspects of the invention, and referring
now to FIG. 7a, a fastener receiving 300 is shown having a threaded
receiving portion 310. Threaded receiving portion 310 receives a
ring fastener into a fastener receiver body portion 316. Threaded
receiving portion 310 has an outer circumference smaller than the
circumference of the aperture through which it will be installed.
In some embodiments, a fastening aperture 315 is disposed in a body
portion of fastener receiver 300; in other embodiments, fastening
aperture 315 is sized so as to receive a padlock or other
mechanical locking mechanism. According to certain embodiments,
support member 320 is swaged into an aperture rather than threaded,
using methods and means for swaging described in greater detail
below. As seen in FIG. 7b, in certain embodiments support shelf 320
has a receiving channel 305 formed around an external circumference
so as to receive a lock washer or the like.
[0070] Turning now to FIG. 8a, a further aspect of the invention is
shown comprising a ring fastener 355 and forming tool 350
combination. In one example embodiment, the forming tool is adapted
to engage at least a portion of a ring fastener support member,
such as for example, support member 260, as shown in FIG. 6a. In
other example embodiments, the forming tool is essentially a
staking tool 350 as shown in FIG. 8a. In the example embodiment
depicted in FIG. 8a, forming tool 350 is a cylindrical housing, but
in other embodiments it is contemplated that forming tool is conic
or funnel shaped, and those of ordinary skill in the art will
appreciate that other forming tool geometries, and combinations of
forming tool geometries, will admit to satisfactory results
according to the invention.
[0071] In one example method, forming tool 350 is employed by
feeding a threaded shaft portion of ring fastener 355 through an
interior cylindrical portion of forming tool 350, and then pressing
staking protrusion 360 against support member 370 with sufficient
force to dent or otherwise deform the support shelf 370. When
staking protrusion 360 is pressed against support member 370 with
sufficient force to increase the outer circumference of support
member 370, ring fastener 355 cannot subsequently be easily removed
from the assembly. Thus, after such an operation, the support
member would be suitable for supporting, in one example embodiment,
the ring fastener 355 though an aperture (e.g., 130, 140) of a
given tab member (e.g., 176, 178).
[0072] According to one embodiment, the force required for staking
protrusion 360 to deform support member 370 varies in proportion to
the characteristics of the material from which ring fastener 355 is
made. In one example embodiment, the amount of force required for
staking protrusion 360 to deform support member 370 is between
around 250 pounds and around 1,000 pounds per square inch. In other
embodiments, however, satisfactory staking results are achieved by
using less than around 250 pounds of force per square inch. In
applications in which ring fastener 355 is formed from a less
malleable material, a force greater than around 1,000 pounds per
square inch is required for staking protrusion 360 to deform
support member 370.
[0073] FIG. 8b is a close up view of ring fastener 355 and forming
tool 350, shown after staking portion 360 has deformed portions
365, 367 of support member 370. Deformed portions 365, 367 are
depicted in this embodiment as having been formed on opposite sides
of support member 370; however, in alternative embodiments, only
one deformed section 367 is formed on the support member 370 by
applying force to staking protrusion 360. In various other
embodiments, the entirety of support member 370 is deformed using
staking portion 360.
[0074] FIG. 8c is a cross-sectional view of the embodiment shown in
FIG. 8a, further comprising a forming tool 350 having a single
staking protrusion 360. In other embodiments, multiple staking
protrusions are disposed around a head portion of forming tool 350
so as to deform multiple sections of the support member 370 when
sufficient force is applied to the staking protrusions. During a
staking operation, ring fastener 355 is inserted into an aperture
formed through a body portion of a tab member; a forming tool 350
is then fit over a threaded shaft portion of the ring fastener, and
force is applied to the staking protrusion 360 (for example, by
striking the fastener housing with a hammer or a mallet), until
deformed regions develop around a circumference of support member
370.
[0075] In another example embodiment, the forming tool is adapted
to engage at least a portion of a ring fastener receiver, such as
for example, fastener receiver 300 as shown in FIG. 7a. In other
example embodiments, the forming tool 400 is essentially a swaging
tool as shown in FIG. 9b. As seen in FIGS. 9a-9c, portions of a
fastener receiver 300 may be deformed by means of, for example, a
swaging tool (e.g., 400) or the like in order to make removal of
the fastener receiver more difficult after installation is
complete. For example, as seen in FIG. 9b, a swaging tool 400
comprises a body portion and a swaging portion 402. The swaging
portion is forcefully applied to a receiving portion 310 disposed
in fastener receiver 300 (see FIG. 9a) so as to deform a threaded
region of receiving portion 310 and inhibit subsequent
tampering.
[0076] It should be recognized that various other example
embodiments may provide that at least a portion of the apparatus
may be adapted for use on various utility service enclosures,
transportation or cargo containers or on other enclosures needing a
securing apparatus (for example, in various embodiments having
tamper-evident seal features) or a locking apparatus. Moreover, a
utility service enclosure or other containers, for example, may
have various compatible configurations, shapes and sizes (e.g.,
with the apparatus or at least a fastening portion of the
apparatus) and be used in the electric utility industry, (e.g., a
meter box) as well as in the gas, water, cable, TV utility
industries or in the shipping or transportation industries.
[0077] In another example embodiment, at least a fastening portion
(e.g., a cylindrical ring fastener and fastener receiver
combination; fastener and receiver housings, any of various barrel
lock devices, threaded or unthreaded-type attaching or fastening
devices and systems or other types of fastening assemblies or
components) or any of various elements of the apparatus may be
adapted to secure a plurality of structures (e.g., having any of
various configurations and being used with enclosures, utility
service enclosures (e.g., electrical, gas, water, etc.), shipping
or transportation containers (e.g., for use in land, air or sea
transport) or cargo vessel panels or doors, or other types of
panels (e.g., flat, curved or other security panels or the like),
structures, or containers needing to be secured) with each of the
plurality of structures in some embodiments defining an aperture
therein or some fastenable structural component or feature. As
noted, the plurality of structures having apertures may be any of a
variety of structures. In one example embodiment, the plurality of
structures comprise first and second ends of any of various types
of ring meter socket rings, which may be connected or disconnected,
with the ring being adapted to mount a meter to a meter box
structure. Each of the first and second ends of the ring, in one
example embodiment, defines at least one aperture therein
respectively for use with the at least a fastening portion.
[0078] In other example embodiments tamper-evident sealing features
may be provided. A seal may comprise the at least a fastening
portion of the apparatus, in some embodiments configured similarly
to a locking pin (or, in other example embodiments, various types
of barrel locks, or as noted earlier herein) which is adapted to
unite a plurality of structures. One example of such structures
would be the ends of a meter ring having apertures. However, the
locking pin could also be configured to be used to unite a
plurality of structures, used with a utility service enclosure, or
for example used to lock (and/or seal or create a tamper-evident
seal to indicate tampering with), for example, utility enclosures
doors, lids or other secured panels, meter boxes, or trucking,
shipping, airline or other transportation or cargo containers or
other enclosures. The plurality of structures could include
plate-like structures having apertures, engageable protrusions, or
other engageable structural configurations such that the plate-like
structures could be united with the at least a fastening portion of
the apparatus to secure enclosures used in various industries.
