Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to a quick release
connector capable of allowing a first component to be attached to
and released from a second component. More particularly, the
present application involves a quick release connector that, can be
incorporated into a microphone stand, a boom arm, or a ball head to
allow a microphone to be quickly and easily removed and attached.
When attached, vibration on the microphone is minimized and a
smooth connect/disconnect mechanism minimizes unwanted noise and
feedback during the attachment and release steps.
BACKGROUND
[0002] During musical performances, there is frequently a need to
adjust or swap out microphones. This can occur as a result of a
malfunctioning microphone or between musical sets a need exists to
change the type or location of a microphone. Heretofore
conventional any methods of swamping out microphones were time
consuming and/or resulted in undesired noise during the microphone
switch. In addition, many conventional microphones holders do not
provide a sufficient vibration free connection. As a result,
vibrations of the microphone can occur during a performance which
leads to a loss of sound quality and the transmittal of vibrations
and undesired acoustical feedback or undesired background noise. As
such, there remains room for variation and improvement within the
art.

DETAILED DESCRIPTION OF REPRESENTATIVE EMBODIMENTS
[0021] Reference will now be made in detail to embodiments of the
invention, one or more examples of which are illustrated in the
drawings. Each example is provided by way of explanation of the
invention, and not meant as a limitation of the invention. For
example, features illustrated or described as part of one,
embodiment can be used with another embodiment to yield still a
third embodiment. It is intended that the present invention include
these and other modifications and variations.
[0022] It is to be understood that the ranges mentioned herein
include all ranges located within the prescribed range. As such,
all ranges mentioned herein include all sub-ranges included in the
mentioned ranges. For instance, a range from 100-200 also includes
ranges from 110-150, 170-190, and 153-162. Further, all limits
mentioned herein include all other limits included in the mentioned
limits. For instance, a limit of up to 7 also includes a limit of
up to 5, up to 3, and up to 4.5.
[0023] The present invention provides for a quick release connector
10 as shown in an engaged orientation (FIG. 1) and a disengaged
orientation (FIG. 2.). The connector 10 is similar in materials and
construction of various quick release connectors such as those set
forth in U.S. Pat. No. 6,561,523 in which is incorporated herein by
reference. The present invention is also useful for providing a
quick release connector mechanism for a variety of adjustable joint
microphones and holders including those set forth in provisional
application No. 61/626,401 and in US Design application entitled
Holder for Music Accessories filed Sep. 26, 2012 having Docket
Number ACC-24-D and Express Mail Label EM 545861043 US and which
are both incorporated herein by reference. As seen in the above
referenced applications, the base of any number of ball head
structures and various holders set forth herein can be adapted so
as to be carried by a releasable member such that the various
holders and ball head structures can be rapidly installed and moved
on a variety of stands, tripods, boom arms and various holders for
microphones, cameras and related equipment.
[0024] One disadvantage of the prior art is that conventional quick
release connectors are not suitable for microphone and sound
amplified equipment. Conventional quick release mechanisms employ a
circumferential groove defined by a shaft which is releaseably
engaged by ball bearings carried within a receiving member and
adapted to engage the groove of the shaft. In accordance with the
present invention, it has been found that an improved vibration
resistant connector can be provided by having a plurality of ball
bearings which engage a smooth, non-grooved shaft. This allows for
a precise press fit connection between a receiving member 12 and a
releasable member 140 which can provide in excess of 2,000 pounds
of support between the connector pieces. In addition to use with
microphones and sound equipment, the quick release adaptor is also
useful for securing cameras to tripods and other structures where
the transmittal of vibration from the tripod to the camera needs to
be minimized. As such, the quick release connector can be used to
attach a camera to a tripod or other support structures used to
attach a mounting plate or camera to a camera tripod head.
[0025] The present invention requires only a minimal lateral
displacement of associated ball bearings relative to a receiving
member 12 of a connector 10. This arrangement allows higher
tolerances to exist between the compressive forces of the ball
bearings which are used to secure a shaft of a releasable member.
The applied force of the ball bearings, relative to the shaft is
supplied from multiple directions. Accordingly, it has been found
that such arrangement using a plurality of ball bearings minimizes
vibration which may otherwise be transmitted along the quick
release connector. As such, the reduction of vibrations improves
the acoustic quality of any microphones that may be supported
directly or indirectly via the quick release connector. As best
seen in reference to FIG. 3, a plurality of ball bearings such as
ball bearings 130, 132, and 134 can engage the flat planar surfaces
of an adjacent hexagonal shaft. Optionally, one or more of the
overlapping surfaces of the interengaged parts can further define a
combination of apertures and pins which will mate together to
prevent rotation. Prevention of rotation between the two portions
of the releasable connectors 10 serves to minimize any slight
vibration that might otherwise occur and therefore provide a more
acoustically clean sound from the microphone.
[0026] As seen in reference to FIGS. 1-5, a quick release connector
10 is provided that has a receiving member 12 that has a bore 14
that is a through bore that extends in a longitudinal direction 22
from a first terminal end 24 of the receiving member 12 to a second
terminal end 26 of the receiving, member, wherein a slot 30 extends
in the longitudinal direction and is defined through a portion of
the receiving member 12 from an exterior surface 18 of the
receiving member to the bore 14 of the receiving member, wherein
the receiving member has a step 28 on the exterior surface 18.
[0027] The engagement member 50 is attached to the receiving member
12 such that the engagement member 50 and the receiving member 12
do not move relative to one another, wherein the engagement member
50 has an inner surface 52 that has an inclined portion 56. A slide
member 90 moves in the longitudinal direction relative to the
receiving member 12 and the engagement member 50. The slide member
90 has a bore 92 that is a through bore that extends in the
longitudinal direction from a first terminal end 94 of the slide
member 90 to a second terminal end 96 of the slide member 90. An
aperture 102 is defined through a portion of the slide member 90
from an exterior surface 98 of the slide member to the bore of the
slide member, and wherein the slide member further has a step 108
on an interior surface 100 of the slide member.
[0028] A ball 130 is located in both the slot 30 and the aperture
102, such that the ball 130 engages the inclined portion 56 of the
engagement member 50. A spring 136 engages the step 108 of the
receiving member 12 and the step 108 of the slide member 90. As
seen in the Figures, a releasable member 140 has a shaft 142 that
is at least partially located within the bore 14 of the receiving
member 12 when the shaft 142 is attached to the receiving member
12. The shaft 142 is also attached to the receiving member 12 when
the ball 130 engages the shaft 142. Shaft 142 can be of any number
of shapes including circular so long as the bore 14 of the
receiving member 12 can accommodate the shaft and do so in, a way
which the ball bearing 130 and 132.
[0029] The bore 14 of the receiving member 12 from the second
terminal end 26 of the receiving member 12 to a location between
the first and second terminal ends (24, 26) of the receiving member
12 in the longitudinal direction 22 may have a hexagonal
cross-sectional shape, wherein the shaft 142 of the releasable
member 140 has a hexagonal cross-sectional shape such that six
planar surfaces 144 make up an exterior surface 146 of the shaft
142, wherein the six planar surfaces 144 of the shaft 142 are all
flat and lack depressions thereon.
[0030] A pin 170 may be optionally located within the receiving
member 12, having a wobble projection 174 located at a terminal end
172 of the pin 170. The longitudinal axis 20 of the receiving
member 12 extends through the wobble projection 174, and the shaft
142 of the releasable member 140 has a terminal end 156, and
defines a wobble projection aperture 158, wherein the wobble
projection 174 is located in the wobble projection aperture 158
when the shaft is attached to the receiving member. The engagement
of the projection 174 and aperture 158 can help eliminate unwanted
vibration by the seating of the two component parts.
[0031] The releasable member 140 has a flange 148 that defines a
plurality of rotational alignment member receiving members 152 and
154, wherein the plurality of rotational alignment member receiving
apertures 152 and 154 each engage one of a plurality of rotational
alignment apertures 72 and 74 when the shaft 142 is attached to the
receiving member 12, and wherein the releasable member 140 has
external threading 150 that engages a first component of a
microphone stand, a boom arm, a microphone, a camera, a tripod, or
a similar component.
[0032] The quick release connector receiving member has a second
slot 32 and a third slot 34 that each extend in the longitudinal
direction and are defined through the portion of the receiving
member from the exterior surface of the receiving member to the
bore of the receiving member, wherein the first slot 30, the second
slot 32, and the third slot 34 are located at different degrees
about the longitudinal axis. The receiving member has internal
threading 36 that engages a second component such as a microphone,
a stand, a boom arm, a camera, a tripod, or similar component.
[0033] The slide member 90 may have a second aperture 104 and a
third aperture 106 that are each defined through the portion of the
slide member 90 from the exterior surface of the slide member to
the bore of the slide member, wherein the first aperture 102, the
second aperture 104, and the third aperture 106 are located at
different degrees about the longitudinal axis.
[0034] Further, a second ball 132 is located in both the second
slot 32 and the second aperture 104, wherein the second ball 132
engages the inclined portion 56 of the engagement member 50. A
third ball 134 is located in both the third slot 34 and the third
aperture 106, wherein the third ball 134 engages the inclined
portion 56 of the engagement member 50 such that when the shaft 142
is attached to the receiving member 12, the second ball 132 and the
third ball 134 engage the shaft.
[0035] The portion of the slide member which is tapered directly
faces the inclined portion of the inner surface of the engagement
member. Further, the slide member has a gripping element 112 on an
exterior surface of the slide member.
[0036] One variation of the quick release connector may comprise a
receiving member 12 that has a longitudinal axis 20, wherein the
receiving member 12 has a bore 14 that extends in a longitudinal
direction, and the receiving member has a slot 30 that extends in
the longitudinal direction and is defined through a portion of the
receiving member 12 from an exterior surface of the receiving
member to the bore 14 of the receiving member 12.
[0037] The slide member 90 may move relative to the receiving
member 12 in the longitudinal direction between an attached
position and a detached position. The ball 130 has at least a
portion of the ball located in the bore 14 of the receiving member
and in the slot 30 of the receiving member 12 when the slide member
90 is in the attached position. When the slide member 90 is in the
detached position no portion of the ball 130 is located in the bore
14 of the receiving member 12. The releasable member 140 is at
least partially located in the bore 14 of the receiving member 12
and is engaged by the ball 130 when the slide member 90 is in the
attached position, wherein when the slide member 90 is in the
detached position the releasable member 140 is removable from the
bore 14 of the receiving member 12.
[0038] The slide member 90 has a bore 92 that extends in the
longitudinal direction, wherein the slide member 90 has an aperture
102 that is defined through a portion of the slide member from an
exterior surface 98 of the slide, member to the bore 92 of the
slide member 90, wherein a portion of the ball 130 is located in
the aperture 102 when the slide member is in the attached position.
The connector comprises an engagement member 50 that does not move
relative to the receiving member 12, wherein the engagement member
50 has an inner surface 52 that has an inclined portion 56, wherein
the ball 130 engages the inclined portion 56 of the inner surface
52 of the engagement member 50 when the slide member is in the
attached position, and wherein the ball 130 does not engage the
inclined portion 56 of the inner surface 52 of the engagement
member 50 when the slide member is in the detached position.
[0039] The slide member has a portion that is a tapered portion 110
and directly faces the inclined portion 56 of the inner surface 52
of the engagement member 50. The slide member further defines a
gripping element 112 on an exterior surface of the slide member.
The slide member has a step 108 on an interior surface of the slide
member and the receiving member has a step 25 on the exterior
surface of the receiving member. A spring 136 engages the step 28
of the receiving member and that engages the step 108 of the slide
member, such that when the spring is biased, the biasing force of
the spring urges the slide member to the attached position.
[0040] The releasable member has a flange that defines two
rotational alignment members wherein the two rotational alignment
members each engage one of the two rotational alignment member
apertures when the releasable member is at least partially located
in the bore of the receiving member and is engaged by the ball when
the slide member is in the attached position. The releasable member
has external threading 150 that engages a first component, such as
a microphone, and wherein the receiving member has internal
threading 36 that engages a second component such as microphone
stand, tripod, boom arm or the like.
[0041] The quick release connector may have a releasable member 140
having a flange that defines two rotational alignment members 152,
154, wherein the two rotational alignment members each engage one
of the two rotational alignment apertures 72, 74 when the portion
of the releasable member 140 is in the bore 54 of the engagement
member 50. When the slide member 90 is in the attached position,
the location of the releasable member relative to the engagement
member is fixed. While the arrangement of the rotational alignment
members and the rotational alignment apertures is described in a
preferred embodiment, it is understood and appreciated that an
alternative arrangement can include having the flange defining the
alignment apertures and the corresponding alignment members project
from a corresponding surface of the engagement member 50.
[0042] As best seen in reference to FIG. 5, a terminal end 26 of
receiving member 12 can define a plurality of apertures similar to
apertures 72 and 74 described earlier. By providing a plurality of
receiving apertures, the receiving member and the releasable member
can provide ready engagement between the respective alignment
members 152 and 154 carried by flange 148. In another words, any
orientation of a multi-sided shaft 142 will bring about a proper
alignment of the pair of rotational alignment members 152 and 154
relative to the plurality of receiving apertures 72.
[0043] The provision of rotational alignment members with
associated alignment apertures is not believed necessary for all
applications. However, for structures subjected though a large
amount of weight or torsion rotation such as the use of heavy booms
arms, it is believed that the additional locking mechanism between
the pins and apertures provides an, even greater degree of
vibration and vibration dampening or transmittal through the quick
release connector.
[0044] Another aspect of the present invention is directed to a
stand particularly useful as a stand for holding microphones, music
stand accessories and cameras. As such, the music stand is useful
to use with the quick release connector 10 described herein. As
best seen in reference to FIG. 6, a music stand 300 may be in the
form of a tripod structure having a plurality of three legs 310.
Each of the legs 310 defines a first end 312 and a second end 314.
As been seen in reference to FIGS. 8-11, a slot 316 is defined
through an upper surface of leg 310, slot 316 providing
communication between an, upper and lower surface of a hallow
portion of leg 310. As seen in reference to and exploded view of
FIG. 11, the first end 312 of leg 310 defines a housing 318. The
interior of housing of 318 is adapted for receiving a pawl 322
carried by a rod 320. Rod 320 is housed within an interior of the
hollow leg and further defines a pair of apertures 324 and 324'. As
seen in reference to FIG. 9, aperture 324 and 324' can be used with
fasteners as illustrated to secure a bottom surface of a release
tab 350 to an upper surface of leg 310.
[0045] As best seen in reference to FIGS. 10 and 11, rod 320 is
insertable within a hollow interior of leg 310. A spring 330 is
positioned along a terminal end 326 which when placed within an
interior leg 310 and provides a tensioning and biasing force for
rod 320. A terminal end of rod 320 defines a pawl 322 which may be
in the form of a single tooth pawl and is adapted for interengaging
with corresponding teeth 362 defined by a ratchet 360. As best seen
in reference to FIGS. 9 and 14, a portion of the ratchet 360 is
adapted for engaging the housing 318 of leg 300. The
interengagement of the pawl 322 with the ratchet 360 and ratchet
teeth 362 allows for a pivoting movement of the leg 300 relative to
a vertical axis of the music stand.
[0046] Leg housing 318 is defined by two parallel edge walls 332
and 334, a curved rear wall 336 and bottom wall 338. Bottom wall
338 defines a bore receiving rod 320 therein so as to be in
communication with the interior of leg 310. A rear wall 368 of
ratchet 360 provides the flat surface for engaging a corresponding
wall of base 340, rear wall 368 further defining two opposing edge
walls which provide a mechanical stop for limiting movement of
housing 318 past a substantially perpendicular or a substantially
parallel orientation relative to a vertical axis of the stand.
[0047] Ratchet 360 is further adapted for engaging within a base
receptacle 344 as best seen in reference to FIG. 9. The base
receptacle 344 is defined by adjacent parallel edge walls, a rear
wall, and a top wall. Base 340 is adapted for receiving both a
portion of the pawl 322 along with the leg housing 318. Base 340
further defines a pair of opposing apertures 342 and 342' which may
be treaded and are used to secure leg housing 318 via aligned
apertures 319 and 319' to base 340. As best seen in FIG. 16,
ratchet 360 defines a corresponding bore 364 from, one side to an
opposite side for securement within housing 318 and base 340.
[0048] As best seen in reference to FIGS. 7, 15 and 16, the release
tab 350 has an upper textured surface 352 (FIG. 7) and a lower
arcuate surface 346 adapted for a sliding movement along a curved
extension surface of the leg 310. Extending from lower surface 354
is an attachment plate 356 configured to fit within the dimensions
of slot 316 and defining a pair of apertures 358 therein in used to
secure release tab 350 by fasteners inserted through rod apertures
324 and 324'.
[0049] The interaction between the ratchet 360 and the pawl 322
allows leg 310 to be freely pivoted in a downward direction. By
sliding the release tab 350 in a direction of leg end 314, the
release tab 350 moves rod 320 in a similar direction, compressing
spring 330. The movement of rod 320 releases pawl 322 from the
ratchet 362 teeth defined by ratchet 360. This allows the movement
of leg 310, leg 310 now free to pivot along a connector extending
through leg housing 318 and apertures 319 and 319', ratchet 360,
and secured through the aligned apertures 342 and 342' defined by
base 340. When the releasing tab 350 is disengaged, spring 330
provides a tensioning force which moves rod 320 and pawl 322 into
an engagement position within ratchet 360 and ratchet teeth 362.
The engagement prevents further movement of the leg in an upward
direction.
[0050] The advantages of the leg configuration for the music stand
is such that a user can adjust a position of a microphone, relative
to the user, by bringing the microphone forward, backward, or to a
left or a right of the user. By engaging and moving only one leg,
the relative position of the microphone or other equipment carried
on the end of the stand can be varied. Such an ability to fine tune
a position of the music stand and any accompanying microphone is
much quicker and far less cumbersome than manual adjustments to the
microphone. Such an ability to fine tune a position of the music
stand and the accompanying microphone is much quicker and far less
cumbersome than raising and lowering a vertical telescopic post
associated with music stands or repositioning a microphone within
the microphone holder. By a simple quick release of the release tab
350 and adjustment to a single leg a user can change the position
of the vertical axis of the music stand so as to better position a
microphone or other accessory in a desired location.
[0051] While the present invention has been described in connection
with certain preferred embodiments, it is to be understood that the
subject matter encompassed by way of the present invention is not
to be limited to those specific embodiments. On the contrary, it is
intended for the subject matter of the invention to include all
alternatives, modifications and equivalents as can be included
within the spirit and scope of the following claims.
