HINGED CONNECTION FOR A RECORDING DEVICE

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to, and the benefit of, U.S. Provisional Patent Application No. 62 / 836,576, filed on April 19, 2019, and entitled "ARTICULATING JOINT APPARATUS FOR AN IMAGING DEVICE".FIELD OF INVENTION

[0002] The present invention relates to a system for couplers that enable mounting and articulation of an accessory relative to a support.BACKGROUND

[0003] Public safety personnel, such as police officers and firefighters, may use cameras to capture events, so that a video and / or audio record exist of what happened in an incident. These cameras may be mounted on vehicles such as cars and drones, and they may also be worn on the body as body worn cameras. Numerous mounting systems exist to mount body worn cameras to personnel. These various mounting systems provide different vantage points. For instance, a body worn camera mounted using a chest mount will have a different vantage point compared to a body worn camera mounted on a shoulder, or epaulette, mount. While many mounting systems are designed to provide a consistent camera perspective, variations within body worn camera mounts as well as user variation lead to variations in the perspective captured by the camera.

[0004] Some mounts allow a user to modify the pitch of a body worn camera, however the articulation methods require bulky hardware, and sometimes require the user to use tools to modify the pitch of the camera. US 2014 / 0199859 describes an accessory mounting assembly.BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

DETAILED DESCRIPTION

[0006] Aspects of this disclosure relate to a low profile articulating joint configured to couple an accessory (e.g., camera, recording device, microphone, etc.) to a support (e.g., article of wear, uniform, etc.). The low profile articulating joint may enable the accessory to articulate relative to the support, such that the pitch of the accessory (and thus field of view for a camera), may be adjusted and secured in a desired orientation. The support may permanently or releasably couple to an article of wear and / or individual via a mounting system.

[0007] In various embodiments, an articulating joint system, such as articulating joint system 19 is disclosed. With reference to FIG. 1A, articulating joint system 19 may comprise an articulating joint 1, an accessory 16, and a support 18. Accessory 16 may comprise a device such as a recording device (e.g., digital video recorder, microphone, camera, etc.). Support 18 may comprise a structure on which accessory 16 is configured to be supported, such as an article of wear, a mount, a uniform, a helmet, etc. Articulating joint 1 may couple accessory 16 with support 18. In some embodiments, articulating joint 1 may be permanently coupled with accessory 16 and be configured to releasably engage support 18. For example, articulating joint 1 may be coupled with accessory 16 via fasteners, adhesives, etc. In other embodiments, articulating joint 1 may be permanently coupled with support 18 and be configured to releasably engage accessory 16. In yet other embodiments, articulating joint 1 may be configured to releasably engage both support 18 and accessory 16. In still other embodiments, articulating joint 1 may be permanently coupled with accessory 16 and support 18. Articulating joint 1 may be configured to enable accessory 16 to articulate relative to support 18. For example, articulating joint 1 may enable a user, such as a law enforcement officer, to position a body worn camera in a particular orientation to capture a particular field of view relative to his or her body.

[0008] In various embodiments, FIG. 1B depicts an exploded view of articulating joint 1. In various embodiments, one or more components of articulating joint 1 may be formed of one or more rigid, durable materials able to withstand force(s) applied to the articulating joint 1 during use. For example, one or more components of articulating joint 1 may include one or more rigid, plastic materials, metal materials, and / or composite materials. The one or more rigid materials may include corrosion-resistant materials, UV resistant materials, and / or any other suitable material configured to at least partially withstand environmental factors. Rigid materials may include metals and metallic alloys (e.g., aluminum, steel, titanium, etc.), composites (e.g., fiberglass, carbon fiber, etc.), plastics (e.g., polycarbonate, acrylonitrile butadiene styrene, polyether ether ketone, etc.), and / or the like. The rigid materials may also be treated (e.g., heat-treated, galvanized, anodized, etc.), painted (e.g., powder-coated, e-coated, etc.), and / or similarly modified to aid in withstanding environmental factors.

[0009] Articulating joint 1 may comprise an articulating platform, such as platform 2, and a unitary base, such as base 3. Platform 2 may be configured to couple to one of an accessory 16 and a support 18. In an embodiment, platform 2 may couple to one of accessory 16 and support 18 via coupler 10. Coupler 10 may be configured to releasably or permanently secure one of accessory 16 and support 18 to platform 2. For example, coupler 10 may be sized and shaped and / or comprise various coupling features to enable coupler 10 to releasably or permanently secure one of accessory 16 and support 18 to platform 2. Coupler 10 may be fastened to platform 2 via fastener 11. In another embodiment, coupler 10 is fastened to platform 2 via a double-sided adhesive. In yet another embodiment, coupler 10 is unitary with platform 2. A person of ordinary skill in the art will appreciate that any coupling device may be substituted for coupler 10, such as a male side of a bayonet mount, a female side of a bayonet mount, a cover and / or base as disclosed in U.S. Patent Number 9,756,930, which is herein incorporated by reference in its entirety, etc.

[0010] Articulating joint 1 may comprise a first coupling wedge, such as first wedge 4a, a second coupling wedge, such as second wedge 4b, a knob 5, a first compression spring 8a, a second compression spring 8b, and / or a nub 6. A shaft with a threaded region, such as threaded fastener 9, may be configured to join first wedge 4a, second wedge 4b, knob 5, first compression spring 8a, second compression spring 8b, nub 6, and base 3. In various embodiments, first wedge 4a, second wedge 4b, knob 5, first compression spring 8a, second compression spring 8b, nub 6, and base 3 may be part of a base assembly coupled together via threaded fastener 9.

[0011] In an embodiment, threaded fastener 9 may comprise a bolt. Threaded fastener 9 may comprise a bolt having a head 15. Head 15 may comprise features configured to enable tightening and loosening of threaded fastener 9. For example, head 15 may be sized and shaped (e.g., square shaped, hexagonal shaped, etc.) to engage a wrench, a socket, and / or the like. Head 15 may also comprise features configured to engage a hex wrench, a slotted screwdriver, a Phillips screwdriver, and / or the like. Threaded fastener 9 may comprise a threaded surface configured to engage one or more components of articulating joint 1 and / or the base assembly. For example, an outer surface of threaded fastener 9 may entirely comprise a threaded surface. As a further example, only a portion of an outer surface of threaded fastener 9 may comprise a threaded surface. For example, in various embodiments wherein threaded fastener 9 is configured to engage nub 6 to join the base assembly, only an end portion of threaded fastener 9 distal head 15 may comprise a threaded surface. The end portion of threaded fastener 9 comprising the threaded surface may comprise dimensions configured to engage a threaded insert 7 of nub 6.

[0012] In various embodiments, threaded fastener 9 and knob 5 may comprise a unitary object. For example, knob 5 may comprise a head of threaded fastener 9. In that regard, rotation of knob 5 (e.g., clockwise or counterclockwise rotation) may similarly rotate threaded fastener 9. In various embodiments, knob 5 may be rigidly fastened with threaded fastener 9. For example, knob 5 may be heat staked (e.g., heat staked to threads and / or head 15), welded, or otherwise coupled to threaded fastener 9, thereby coupling rotation of knob 5 with threaded fastener 9 while also preventing threaded fastener 9 from disengaging knob 5. In various embodiments, threaded fastener 9 may be inserted through knob 5 to couple threaded fastener 9 to knob 5. For example, knob 5 may comprise a profile 13 defining a recessed opening on an outer surface of knob 5. Profile 13 may be sized and shaped to receive head 15 of threaded fastener 9. Head 15 of threaded fastener 9 may be configured to at least partially fit within profile 13 of knob 5, whereby profile 13 couples rotation of threaded fastener 9 with knob 5. In various embodiments, knob 5 may comprise structural features, surface coatings, and / or the like configured to provide a gripping surface, such as, for example, a knurled surface configured to improve grip.

[0013] In various embodiments, one or more components of articulating joint 1 and / or the base assembly may be tightened and / or loosened to control articulation of platform 2 into (or between) various orientations (e.g., as further described with reference to FIG. 5). For example, loosening components of the base assembly along axis 12 may enable platform 2 to be in an open state whereby platform 2 may articulate into various orientations (e.g., by decreasing engagement between platform 12 and wedge 4A and / or wedge 4B, as discussed further herein). Tightening components of the base assembly along axis 12 may cause platform 2 to be in a locked state whereby platform 2 is unable to articulate into various orientations (e.g., by increasing engagement between platform 12 and wedge 4A and / or wedge 4B, as discussed further herein). In various embodiments, loosening (e.g., rotating counterclockwise, decreasing thread engagement of, etc.) threaded fastener 9 relative to threaded insert 7 of nub 6 enables platform 2 to be articulated among a plurality of orientations as shown in FIG. 5. The pitch of the teeth (e.g., first set of teeth 20a / 40a and second set of teeth 20b / 40b) may define the degree of rotation between each of the plurality of orientations. For example, first set of teeth 20a / 40a and second set of teeth 20b / 40b may engage one another in angular steps. For example, the angular step may be between 0.1 degrees and 0.25 degrees, between 0.25 degrees and 0.5 degrees, between 0.5 degrees and 1 degree, and between 1 degree and 2 degrees. In various embodiments, tightening (e.g., rotating clockwise, increasing thread engagement of, etc.) threaded fastener 9 relative to threaded insert 7 retains platform 2 in a particular orientation relative to base 3 in a locked position.

[0014] FIG. 2 shows a perspective view of a platform 2, in accordance with various embodiments. Platform 2 may comprise a surface 25 (e.g., a receiving surface) having a first end 21a (e.g., first platform end, etc.) opposite a second end 21b (e.g., second platform end, etc.). Surface 25 may include a mounting feature 24. In an embodiment, mounting feature 24 enables fastener 11 to couple coupler 10 with platform 2. Mounting feature 24 may prevent rotation of coupler 10 relative to platform 2. Mounting feature 24 may comprise a structure such as a recess and / or protrusion configured to engage coupler 10 to lock an orientation of coupler 10 relative to platform 2. In various embodiments, coupler 10 may also be coupled to surface 25 using any other suitable technique. In various embodiments, coupler 10 and platform 2 may comprise a unitary object.

[0015] In various embodiments, platform 2 may comprise a hinge (e.g., a first hinge, a platform hinge, etc.). The hinge may be configured to interact with the base assembly, such as base 3 and / or wedges 4a and 4b, to enable articulating joint 1 to articulate between orientations. The hinge may extend perpendicularly from surface 25 between first end 21a and second end 21b. The hinge may comprise a single structure configured to enable articulation of articulating joint 1. The hinge may also comprise a plurality of structures configured to enable articulation of articulating joint 1. For example, the hinge may comprise a first hinge joint and a second hinge joint. The first hinge joint may extend downward from surface 25 proximate first end 21a. The second hinge joint may extend downward from surface 25 proximate second end 21b.

[0016] Each of first tab 23a and second tab 23b may extend perpendicularly from surface 25 of platform 2. First tab 23a may include a hole (e.g., passageway, thru hole, bore, etc.), such as first hole 22a (obscured from view). Second tab 23b may comprise a hole, such as second hole 22b. In various embodiments, platform 2 may comprise a hinge extending between first end 21a and second end 21b, such that first hole 22a is contiguous with second hole 22b. Second hole 22b may be concentric with a first hole 22a of first tab 23a. First tab 23a may include a first set of teeth 20a. First set of teeth 20a may be positioned radially around first hole 22a. First set of teeth 20a may circumscribe first hole 22a. First set of teeth 20a may project outward from first tab 23a toward first end 21a of platform 2. In various embodiments, second tab 23b may include a second set of teeth 20b. Second set of teeth 20b may be positioned radially around second hole 22b. Second set of teeth 20b may circumscribe second hole 22a. Second set of teeth 20b may project outward from second tab 23b toward second end 21b of platform 2. A number of teeth of first set of teeth 20a may be equal to the number of teeth of second set of teeth 20b. First set of teeth 20a and second set of teeth 20b may be tapered and configured to mesh with other sets of teeth described further herein. First set of teeth 20a and second set of teeth 20b may comprise a profile similar to that found in a common Hirth coupling.

[0017] In various embodiments, platform 2 may include one or more reliefs. A relief may define a portion of surface 25 configured to receive one or more components of articulating joint 1. For example, a relief may define a void, recess, or the like on surface 25. As a further example, a relief may comprise a portion of surface 25 having a thickness less than a thickness of surface 25 (e.g., a relief thickness is less than an average thickness of surface 25). The one or more reliefs may be configured to contribute to the low profile nature of articulating joint 1.

[0018] Platform 2 may comprise a relief 26 (e.g., first relief, dome relief, base relief, etc.). Relief 26 may define a portion of surface 25 configured to at least partially receive dome 36 of base 3 (with brief reference to FIG. 3). In that regard, relief 26 may be sized and shaped to at least partially receive dome 36. For example, relief 26 may define a full recess, a partial recess, and / or a decreased thickness in surface 25 between first end 21a and second end 21b. Relief 26 may be configured to at least partially reduce interference of surface 25 with dome 36 in response to articulating joint 1 being articulated into one or more orientations (e.g., as depicted in configurations 50 and 54, with brief reference to FIG. 5).

[0019] Platform 2 may comprise one or more tab reliefs, such as, for example, a first tab relief 27a (e.g., second relief, etc.) and a second tab relief 27b (e.g., third relief, etc.). First tab relief 27a may define a portion of surface 25 configured to at least partially receive first tab 23a. In that regard, first tab relief 27a may be sized and shaped to at least partially receive first tab 23a. For example, first tab relief 27a may define a full recess, a partial recess, and / or a decreased thickness in surface 25 proximate first end 21a. First tab relief 27a may be configured to allow first tab 23a to interface with first wedge 4a. For example, first tab relief 27a may be sized and shaped to enable first set of teeth 20a of first tab 23a to interface with first set of teeth 40a of first wedge 4a, while still enabling articulating joint 1 to maintain a low profile (as discussed further herein). Second tab relief 27b may define a portion of surface 25 configured to at least partially receive second tab 23b. In that regard, second tab relief 27b may be sized and shaped to at least partially receive second tab 23b. For example, second tab relief 27b may define a full recess, a partial recess, and / or a decreased thickness in surface 25 proximate second end 21b. Second tab relief 27b may be configured to allow second tab 23b to interface with first wedge 4b. For example, second tab relief 27b may be sized and shaped to enable second set of teeth 20b of second tab 23b to interface with second set of teeth 40b of second wedge 4b, while still enabling articulating joint 1 to maintain a low profile (as discussed further herein).

[0020] FIG. 3 shows a perspective view of a base 3, in accordance with various embodiments. Base 3 may comprise a body 31 having a first end 33a (e.g., third end, first base end, etc.) opposite a second end 33b (e.g., fourth end, second base end, etc.). Body 31 may include a top surface 39, a hinge (e.g., second hinge, base hinge, complementary hinge, etc.), and / or a dome 36. The hinge may be configured to interact with platform 2, and / or wedges 4a and 4b, to enable articulating joint 1 to articulate between orientations. The hinge may be located between top surface 29 and dome 36 and extend perpendicularly from base 3. The hinge may be complementary with the hinge of platform 2. The complementary hinge may be configured to cooperate with the hinge of platform 2. The hinge may comprise a single structure configured to enable articulation of articulating joint 1. The hinge may also comprise a plurality of structures configured to enable articulation of articulating joint 1. For example, the hinge may comprise a first hinge joint and a second hinge joint. The first hinge joint may extend from base 3 proximate first end 33a. The second hinge joint may extend from base 3 proximate second end 33b.

[0021] In various embodiments, the hinge may comprise a first tab 35a (e.g., third tab, first base tab, etc.) and a second tab 35b (e.g., fourth tab, second base tab, etc.). First tab 35a may extend perpendicular from first end 33a. Second tab 35b may extend perpendicular from second end 33b. In various embodiments, first tab 35a may include a first hole 30a, and second tab 35b may include a second hole 30b. In various embodiments, base 3 may comprise a complementary hinge extending between first end 33a and second end 33b, such that first hole 30a is contiguous with second hole 30b. Second hole 30b may be concentric with first hole 30a along axis 12.

[0022] Base 3 may further comprise a mounting hole, such as hole 34. Hole 34 may define a void through dome 36. Hole 34 may be configured to receive a fastener for coupling base 3 to a support, accessory, or other structure. In various embodiments, hole 34 may comprise a chamfer 38 configured to receive a flat head countersink fastener. In embodiments, a region of material on base 3, such as dome 36, may gradually change thickness to transfer axial clamping force of a fastener across base 3. A shape, size, and / or thickness of dome 36 may be configured to minimize an overall thickness of articulating joint 1. In some embodiments, a double-sided adhesive may be used to couple body 3 to one of an accessory and a support.

[0023] In various embodiments, base 3 may include one or more recesses. A recess may define a portion of body 31 (e.g., a female receptacle) configured to receive a portion of wedge 4a or wedge 4b (e.g., a male connector). For example, a recess may define a void, recess, receptable, or the like on body 31. As a further example, a recess may define a portion of body 31 having a thickness less than a thickness of body 31 (e.g., a recess thickness is less than an average thickness of body 31). Each recess may be located on a bottom and / or side portion of body 31, proximate first end 33a and / or second end 33b.

[0024] In various embodiments, base 3 may include one or more recesses such as a first undercut 32a (e.g., a first recess, a first dovetail, etc.) and a second undercut 32b (e.g., a second recess, a second dovetail, etc.). First undercut 32a may be sized and shaped to receive a portion of first wedge 4a. In that regard, first undercut 32a may comprise any suitable shape configured to receive a portion of first wedge 4a, such as, for example, a square shape, a rectangular shape, a dovetail shape, a dado shape, etc. First undercut 32a may define a recess in body 31 encompassing a portion of a bottom of body 31 and first end 33a. In various embodiments, first undercut 32a may define a single recess encompassing a portion of a bottom of body 31 and first end 33a extending from a first edge of base 3 proximate top surface 39 to a second edge of base 3 proximate dome 36. The single recess may be configured to receive one or more portions of first wedge 4a (e.g., a first foot in the single recess, a first foot and a second foot in the single recess, etc.). In various embodiments, first undercut 32a may define a plurality of recesses encompassing separate and discrete portions of a bottom of body 31 and first end 33a. The plurality of recesses may each be configured to receive separate portions of first wedge 4a (e.g., a first foot in a first recess and a second foot in a second recess, a first foot and a second foot in a first recess and a third foot in a second recess, etc.).

[0025] Second undercut 32b may define a recess in body 31 encompassing a portion of a bottom of body 31 and second end 33b. Second undercut 32b may be sized and shaped to receive a portion of second wedge 4b. In that regard, second undercut 32b may comprise any suitable shape configured to receive a portion of second wedge 4b, such as, for example, a square shape, a rectangular shape, a dovetail shape, a dado shape, etc. Second undercut 32b may define a recess in body 31 encompassing a portion of a bottom of body 31 and second end 33b. In various embodiments, second undercut 32b may define a single recess encompassing a portion of a bottom of body 31 and second end 33b extending from a first edge of base 3 proximate top surface 39 to a second edge of base 3 proximate dome 36. The single recess may be configured to receive one or more portions of second wedge 4b (e.g., a first foot in the single recess, a first foot and a second foot in the single recess, etc.). In various embodiments, second undercut 32b may define a plurality of recesses encompassing separate and discrete portions of a bottom of body 31 and second end 33b. The plurality of recesses may each be configured to receive separate portions of second wedge 4b (e.g., a first foot in a first recess and a second foot in a second recess, a first foot and a second foot in a first recess and a third foot in a second recess, etc.).

[0026] First undercut 32a and second undercut 32b may form acute angles with first end 33a and second end 33b of base 3, respectively. First undercut 32a and second undercut 32b may be understood in the art as dovetails, therefore base 3 may also be understood as a dovetail base. First undercut 32a and second undercut 32b may be configured to releasably engage (e.g., cooperate, interface, etc.) with first wedge 4a and second wedge 4b, respectively. FIG. 4 depicts an embodiment of first wedge 4a and second wedge 4b configured to releasably engage first undercut 32a and second undercut 32b.

[0027] As illustrated in FIG. 4, first wedge 4a and second wedge 4b may comprise similar shapes and characteristics with one another. In that regard, first wedge 4a and second wedge 4b may be interchangeable and may be configured to perform the same operations based on orientation (e.g., first wedge 4a can replace second wedge 4b to perform the operations of second wedge 4b in articulating joint 1, second wedge 4b can replace first wedge 4a to perform the operations of first wedge 4a in articulating joint 1, etc.).

[0028] First wedge 4a may comprise a first acute edge 44a (e.g., first ramp, first foot, first protrusion, etc.). First acute edge 44a may be configured to releasably engage first undercut 32a of base 3. First acute edge 44a may be sized and shaped to engage first undercut 32a. For example, first acute edge 44a may comprise a size and shape complimentary with first undercut 32a. In that regard, first acute edge 44a may comprise a square shape, a rectangular shape, a dovetail shape, a dado shape, etc., based on the size and shape of first undercut 32a. In various embodiments, first acute edge 44a may comprise one or more protrusions (e.g., feet, ramps, etc.) extending from first wedge 4a. For example, first acute edge 44a may comprise a first protrusion 45a1 and a second protrusion 45a2. First protrusion 45a1 and second protrusion 45a2 may be configured to engage first undercut 32a of base 3. For example, in response to first undercut 32a comprising a single recess, first protrusion 45a1 and second protrusion 45a2 may be both configured to engage the single recess. In response to first undercut 32a comprising a first recess and a single recess, first protrusion 45a1 may be configured to engage the first recess and second protrusion 45a2 may be configured to engage the second recess.

[0029] First wedge 4a may further comprise a first hole 42a. In various embodiments, first hole 42a may be circumscribed by first set of teeth 40a. First set of teeth 40a may be positioned radially around first hole 42a. First set of teeth 40a may project outward from first hole 42a toward first acute edge 44a. First set of teeth 40a may be configured to mesh with first set of teeth 20a of platform 2 in a locked position. In the locked position, first acute edge 44a may be configured to releasably engage first undercut 32a of base 3. In various embodiments, a portion of the outer surface of first wedge 4a defining a circumferential edge of first hole 42a may not comprise first set of teeth 40a. The surface may be flat and / or recessed. The surface may be sized and shaped to engage, abut, and / or retain compression spring 8a (e.g., a retaining surface).

[0030] Second wedge 4b may be similar to first wedge 4a and may comprise similar or same features and functionalities, such as, for example, a second set of teeth 40b, a second hole 42b, and / or a second acute edge 44b. Second acute edge 44b may be similar to first acute edge 44a. Second acute edge 44b (e.g., second ramp, second foot, second protrusion, etc.) may be configured to releasably engage second undercut 32b of base 3. Second acute edge 44b may be sized and shaped to engage second undercut 32b. For example, second acute edge 44b may comprise a size and shape complimentary with second undercut 32b. In that regard, second acute edge 44b may comprise a square shape, a rectangular shape, a dovetail shape, a dado shape, etc., based on the size and shape of second undercut 32b. In various embodiments, second acute edge 44b may comprise one or more protrusions (e.g., feet, ramps, etc.) extending from second wedge 4b. For example, second acute edge 44b may comprise a first protrusion 45b1 and a second protrusion 45b2. First protrusion 45b1 and second protrusion 45b2 may be configured to engage second undercut 32b of base 3. For example, in response to second undercut 32b comprising a single recess, first protrusion 45b1 and second protrusion 45b2 may be both configured to engage the single recess. In response to second undercut 32b comprising a first recess and a single recess, first protrusion 45b1 may be configured to engage the first recess and second protrusion 45b2 may be configured to engage the second recess.

[0031] Second hole 42b may be similar to first hole 42a, and second set of teeth 40b may be similar to first set of teeth 40a. In various embodiments, second hole 42b may be circumscribed by second set of teeth 40b. Second set of teeth 40b may be positioned radially around second hole 42b. Second set of teeth 40b may project outward from second hole 42b toward second acute edge 44b. Second set of teeth 40b may be configured to mesh with second set of teeth 20b of platform 2 in a locked position. In the locked position, second acute edge 44b may be configured to releasably engage second undercut 32b of base 3. In various embodiments, a portion of the outer surface of second wedge 4b defining a circumferential edge of second hole 42b may not comprise second set of teeth 40b. The surface may be flat and / or recessed. The surface may be sized and shaped to engage, abut, and / or retain compression spring 8b (e.g., a retaining surface).

[0032] In an embodiment of articulating joint 1, only first wedge 4a and first tab 23a of platform 2 have sets of teeth, such that in a locked position, only first set of teeth 40a of first wedge 4a and first set of teeth 20a of platform 2 are engaged. The material, profile, and / or geometry of any sets of teeth described herein may be configured to resist a predetermined amount of torque before deforming.

[0033] In various embodiments, first acute edge 44a of first wedge 4a may only comprise first protrusion 45a1 and second acute edge 44b of second wedge 4b may only comprise first protrusion 45b1. In that regard, when oriented in articulating joint 1, protrusions 45a1, 45b1 may be located on opposing sides of articulating joint 1. Having protrusions 45a1, 45b1 on opposing sides of articulating joint 1 may increase stability in articulating joint 1 during tightening, in contrast to having protrusions only on one same side of articulating joint 1.

[0034] In various embodiments, and with reference to FIGs. 1A-4, threaded fastener 9 couples the hinge of platform 2 (e.g., first tab 23a and second tab 23b) with the complementary hinge of base 3 (e.g., first tab 35a and second tab 35b) along axis 12. In some embodiments, threaded insert 7 is disposed within one of first hole 42a of first wedge 4a, first hole 30a of first tab 35a of base 3, and first hole 22a of platform 2. In that regard, threaded fastener 9 may be coupled to threaded insert 7 disposed within first hole 42a, first hole 30a, and / or first hole 22a. In other embodiments, threaded fastener 7 may be disposed within a nub, such as nub 6. In that regard, threaded fastener 9 may be coupled to nub 6. Nub 6 may have a lobular projection 14 (e.g., lobe, lever, etc.) extending from its diameter, to assist in tightening and loosening threaded faster 9 relative to threaded insert 7. Nub 6 may be disposed adjacent first wedge 4a. In various embodiments, nub 6 may be disposed adjacent first tab 35a of base 3 or first tab 23a of platform 2. In some embodiments, first wedge 4a may be rigidly coupled with and / or unitary with first side 33a of base 3.

[0035] FIG. 5 shows an example of various states of articulating joint 1. In a locked position, first set of teeth 42a of first wedge 4a may mesh (e.g., fully engage) with first set of teeth 20a of platform 2, thereby retaining platform 2 in a particular orientation relative to base 3. In a locked position, second set of teeth 42b of second wedge 4b may mesh with second set of teeth 20b of platform 2, thereby retaining platform 2 in a particular orientation relative to base 3. In a locked position, first acute edge 44a of first wedge 4a may cooperate with first undercut 32a of base 3 to secure platform 2 to base 3. In a locked position, translation of first acute edge 44a perpendicular to axis 12 may be restricted by first undercut 32a. In a locked position, second acute edge 44b of second wedge 4b may cooperate with second undercut 32b of base 3 to secure platform to base 3. In a locked position, translation of second acute edge 44b perpendicular to axis 12 may be restricted by second undercut 32b.

[0036] In various embodiments, in an unlocked position, first set of teeth 42a of first wedge 4a may be disengaged with first set of teeth 20a of platform 2, thereby enabling articulation of platform 2 relative to base 3 about axis 12. In an unlocked position, second set of teeth 42b of second wedge 4b may be disengaged with second set of teeth 20b of platform 2, thereby enabling articulation of platform 2 relative to base 3 about axis 12. In an unlocked positioned, first acute edge 44a of first wedge 4a may be disengaged with first undercut 32a of base 3. In an unlocked position, second acute edge 44b of second wedge 4b may disengaged with second undercut 32b of base 3.

[0037] Articulating platform 2 may also rotate about axis 12 from a maximum extent of rotation to a minimum extent of rotation over a plurality of discreet orientations (e.g., articulation states). The maximum extent of rotation and the minimum extent of rotation may be defined at orientations at which platform 2 may not articulate further in a direction in an unlocked position due to a mechanical stop. For example, at a maximum range of rotation, dome 36 of base 3 may contact relief 26 of platform 2. In various embodiments, at a minimum range of rotation, an outer edge of surface 25 of platform 2 may contact top surface 39 of base 3. In various embodiments, accessory 18 coupled to coupler 10 may contact top surface 39 of base 3.

[0038] In various embodiments, a range of rotation may be between the maximum extent of rotation and the minimum extent of rotation. For example, and in accordance with various embodiments, a range of rotation of platform 2 relative to base 3 may be between 10 degrees and 90 degrees. In various embodiments, a range of rotation of platform 2 relative to base 3 may be at any other degree interval between 10 degrees and 90 degrees. In various embodiments, a range of rotation of platform 2 relative to base 3 may be between 10 degrees and 15 degrees, between 15 degrees and 30 degrees, between 30 degrees and 45 degrees, and / or between 45 degrees and 90 degrees. The number of discreet articulation states may be determined by the geometry of first set of teeth 42a / 42b and second set of teeth 20a / 20b as discussed previously herein.

[0039] Articulating joint 1 may be locked into an articulation state by increasing thread engagement of threaded fastener 9 with threaded insert 7. Thread engagement may be increased by rotating knob 5, wherein rotation of knob 5 is coupled with rotation of threaded fastener 9. In various embodiments, a lever extending from nub 6, such as lobular projection 14, may enable a user to exert additional torque to tighten treaded fastener 9 relative to threaded insert 7. Lobular projection 14 may allow a user to impart greater torque with less force, thereby aiding in tightening and / or loosening threaded fastener 9. In another embodiment, nub 6 may have a plurality of ribs to improve grip. In embodiments, nub 6 and / or knob 5 may be rotated, or be prevented from being rotated, with tools, such as a hex wrench, slotted screwdriver, etc.

[0040] Articulating joint 1 may be free to rotate when first set of teeth 42a / 20a and second set of teeth 42b / 20b are disengaged with one another (e.g., in the unlocked position). Decreasing thread engagement of threaded fastener 9 with threaded insert 7 allows first set of teeth 42a / 20a to separate from second set of teeth 42b / 20b. In various embodiments, articulating joint 1 further comprises one or more springs to aid in separating first set of teeth 42a / 20a and second set of teeth 42b / 20b when loosening threaded fastener 9 from threaded insert 7. For example, articulating joint 1 may include a first compression spring 8a and / or a second compression spring 8b. First compression spring 8a may be disposed between first tab 23a of platform 2 and first wedge 4a. First compression spring 8a may exert a separating force on first tab 23a and first wedge 4a. The separating force may push first wedge 4a from first tab 23a as threaded fastener 9 is loosened from threaded insert 7. The separating force exerted by first compression spring 8a may cause first set of teeth 42a of first wedge 4a to separate from first set of teeth 20a of platform 2 in an unlocked position. In various embodiments, second compression spring 8b may be disposed between second tab 23b of platform 2 and second wedge 4b. Second compression spring 8b may exert a separating force on second tab 23b and second wedge 4b. The separating force may push second wedge 4b from second tab 23b as threaded fastener 9 is loosened from threaded insert 7. The separating force exerted by second compression spring 8b may cause second set of teeth 42b of second wedge 4b to separate from second set of teeth 20b of platform 2 in an unlocked position.

[0041] Configuration 50 as illustrated in FIG. 5 depicts articulating joint 1 in an unlocked position in which platform 2 is at a maximum extent of rotation. Platform 2 is at a maximum extent of rotation when a mechanical stop prevents platform 2 from rotating further in a direction. In an embodiment, a mechanical stop is determined by dome 36 contacting relief 26. In an unlocked position in which platform 2 is at a maximum extent of rotation, first compression spring 8a acts on first wedge 4a and first tab 23a of platform 2 to separate first set of teeth 42a of first wedge 4a and first set teeth 20a of first tab 23a of platform 3. Second compression spring 8b acts on second wedge 4b and second tab 23b of platform 2, providing an opposing force between second set of teeth 42b of second wedge 4b and second set of teeth 20b of second tab 23b of platform 2. The force of first compression spring 8a and second compression spring 8b may be overcome by manual rotation of knob 5, threaded fastener 9, and / or nub 6 (e.g., to rotate threaded fastener 9 causing articulating joint 1 to move into the locked position).

[0042] Configuration 52 illustrates articulating joint 1 in an unlocked position in which articulating platform 2 is at a minimum extent of rotation. Articulating platform is at a minimum extent of rotation when a mechanical stop prevents platform 2 from further rotation in a direction opposite the direction of maximum rotation. For example, at the minimum extent of rotation, a surface of platform 2 may contact a top surface of base 3, such as top surface 39 (with brief reference to FIG. 3). In an unlocked position in which platform 2 is at a minimum extent of rotation, first compression spring 8a acts on first wedge 4a and first tab 23a of platform 2 to separate first set of teeth 42a of first wedge 4a and first set teeth 20a of first tab 23a of platform 3. Second compression spring 8b acts on second wedge 4b and second tab 23b of platform 2, providing an opposing force between second set of teeth 42b of second wedge 4b and second set of teeth 20b of second tab 23b of platform 2. The force of first compression spring 8a and second compression spring 8b may be overcome by manual rotation of knob 5, threaded fastener 9, and / or nub 6 (e.g., to rotate threaded fastener 9 causing articulating joint 1 to move into the locked position).

[0043] Configuration 54 shows articulating joint 1 in a locked position in which platform 2 is at a maximum extent of rotation with respect to base 3. Configuration 56 illustrates articulating joint 1 in a locked position in which platform 2 is at a minimum extent of rotation relative to base 3. In a locked position in which platform 2 is at a maximum extent of rotation or a minimum extent of rotation, first set of teeth 42a / 20a are fully engaged with second set of teeth 42b / 20b. In a locked position, first compression spring 8a and / or second compression spring 8b may each have a compressed length. In the unlocked position, first compression spring 8a and / or second compression spring 8b may each have a relaxed length. The compressed length may be shorter than the relaxed length.

[0044] In various embodiments, a method of articulating an articulating joint 1 may include passing threaded fastener 9 through a combination of first hole 42a of first wedge 4a, complementary hinge of base 3, hinge of platform 2, first compression spring 8a, second compression spring 8b, and second hole 42b of second wedge 4b. After passing threaded fastener 9 through the combination of components of articulating joint 1, threaded fastener 9 may be at least partially threaded into threaded insert 7. Prior to fully tightening threaded fastener 9 in a locking direction (e.g., clockwise), platform 2 may be articulated to a desired (e.g., particular) orientation relative to base 3. Once platform 2 is articulated to the desired position, threaded fastener 9 may be rotated in the locking direction until first set of teeth 42a mesh with first set of teeth 20a and / or second set of teeth 42b mesh with second set of teeth 20b. As threaded fastener 9 is rotated in the locking direction, engagement of first acute edge 44a and first undercut 32a and / or engagement of second acute edge 44b and second undercut 32b increases, thereby securing platform 2 relative to base 3. Rotating threaded fastener 9 in the locking direction may include grasping a gripping surface, such as knob 5 and / or nub 6, and turning the shaft in a clockwise direction.
