The outboard plate having features for attachment of a holster or accessory. The inboard and outboard plates having a range of motion with favored positions provided by a detent in a hinge. The belt clamp also includes a spring biased locking mechanism that selectively and releasably connects the lower end of the inboard plate to the lower end of the outboard plate by way of locking posts in the inboard plate that are displaced upwardly from the lower edge of said plate. The outboard locking plate having latching members that are entirely contained (except for opposing actuation buttons) within a compartment formed by two portions of the outboard plate connected by a living hinge. The opposing actuation buttons require a motion in a first direction, such as upwardly, to allow motion in a second direction, such as inwardly, to rotate the latching members inwardly to release the locking posts. The belt may be clamped between the inboard plate and the outboard plate by placing the belt between plates and urging the lower ends of the plates together whereby the locking posts deflect the latching members momentarily opening the locking mechanism. An interior adjustment bar for sizing the belt clamp to varying belt sizes has two outer deflectable prongs and a stabilizing tongue intermediate the prongs. The prongs and tongue are inserted into a selected slot of a stack of slots in the inboard plate for adjustably fixing the bar in the appropriate adjustment place, the tongue precluding excessive and potentially destructive deflection of the deflectable prongs.

In embodiments, a belt clamp includes an inboard plate and an outboard plate that are pivotally coupled at their upper ends. The belt clamp also includes a spring biased locking mechanism that selectively and releasably connects the lower end of the inboard plate to the lower end of the outboard plate. A belt may be clamped between the inboard plate and the outboard plate by placing the belt between plates and pressing the lower ends of the plates together such that locking posts on one plate engage and deflect cooperating and rotatable latch members on the other plate to actuate, that is, momentarily open the locking mechanism.

In embodiments, a belt clamp comprises an inboard plate and an outboard plate connected to the inboard plate at an upper pivoting connection, each plate comprising an upper hinge portion, the upper hinge portions cooperating to form the upper pivoting connection at an upper end of the belt clamp. The hinge may comprise interlaced knuckles with unitary pins extending from select knuckles in one of the inboard plate and outboard plate for being received by inner voids in the other of the inboard plate and outboard plate. A feature and advantage of embodiments is that the use of unitary pin or pins precludes the need of the conventional separate hinge pin extending through the interlaced knuckles.

In embodiments, the locking mechanism includes a pair of latching portions configured as distinct latching members that are rotatably and slidably supported by the outboard plate so that the latching members can translate between an insertion position and a locked position. The latching members can engage with a complementary portion formed on the inboard plate while the latching members are urged inwardly be unlocking forces. Unlocking forces may be formed by ramp portions of the latching members and the complementary portions. In embodiments, unlocking forces are produced when the outboard plate is pressed against the latching members can be used to urge the latching members toward the insertion position. Unlocking forces may also be produced by the user's thumb and the user's index finger. In embodiments, the button portion can also be urged inward the insertion position by squeezing the latching members between the thumb and index finger of the user's hand. Each button portion includes a ribbed finger engaging portion for this purpose. The plates are pivotally connected to one another at a hinge pin that extends through a hinge portion of the inboard plate and a hinge portion of the outboard plate.

The pin may be unitary with one or the other of the inboard plate and outboard plate.

A feature and benefit of embodiments is an interior plate including ramped ribs at the lower end thereof that lead to the locking posts. In embodiments, the ramped ribs allow for easier installation of the belt clamp onto a belt while the belt is being worn by a user, guiding the belt through juncture of the user's pants and the inwardly facing surface of the belt. In embodiments, the ramped ribs have geometry that reduces the likelihood that the belt clamp will snag or catch on the belt or surrounding clothing as compared to similar products.

A feature and benefit of embodiments is an interior plate including locking portions that blend into ramped ribs, giving increased rigidity and strength to the locking posts.

In embodiments, this arrangement reduces the likelihood that the locking posts will be damaged during use while during insertion of the clamp on a belt and during removal of the clamp from a belt.

A feature and benefit of embodiments is an upper pivoting connection between the inboard plate and the outboard plate extending along an upper end of the belt clamp. In embodiments, the upper pivoting connection comprises a hinge portion of each plate that cooperate to form a hinge, the hinge having a hinge width. In embodiments, a ratio of the hinge width to the overall width of the belt clamp is greater than 0.9. This arrangement provides stability, robustness and ease of assembly to the hinge portion. This arrangement also distributes applied forces across a greater area of the hinge portion. In embodiments, the hinge portions of the plates are coupled using a simple assembly process with no separate hinge pin. Hinge knuckles on one of the inboard plate and outboard plate may snap onto hinge pins unitary with the other of the inboard plate and outboard plate.

A feature and benefit of embodiments is an upper pivoting connection between the inboard plate and the outboard plate formed by snapping together a pair of cooperating hinge portions of the plates. In embodiments, each hinge portion includes a plurality of pin portions and a plurality of C-shaped pin receiving portions. In embodiments, each pin portion of the inboard plate mates with a C-shaped portion of the outboard plate. In embodiments, each C-shaped portion of the inboard plate mates with a pin portion of the outboard plate. A feature and advantage of embodiments is a pivoting arrangement having a pin portion that snaps into a corresponding C-shaped portion. This arrangement provides manufacturing advantages including fewer parts, easier assembly, the possibility of performing a repair by replacing a plate, and the possibility of replacing a plate with one or more plates having alternate configurations to suit the preferences of different users.

A feature and advantage of embodiments is a belt clamp made almost entirely of polymeric material, except for springs and fasteners. This arrangement provides ease of assembly and cost efficiencies by minimizing the number of parts and minimizing the number of assembly steps. In embodiments, the pivoting arrangement includes a plurality of polymer pin portions that are received in a corresponding C-shaped portions, the pin portions and the C-shaped portions being integrally formed along upper portions of the plates.

A feature and advantage of embodiments is that the locking mechanism is biased, such as by a spring, to a pre-actuation position and is automatically reset after the belt clamp is opened. The belt clamp can be locked onto a belt at a new position without manual reset of the locking mechanism.

A feature and advantage of embodiments is that the lock mechanism is actuated by the user's thumb and the user's index finger. A feature and advantage of embodiments is that finger receiving buttons of the retaining mechanism are positioned to allow for the most intuitive and ergonomic unlocking of the belt clamp from a belt. This allows the user to press his or her thumb and index finger against the buttons with less tension in the muscles and tendons of the index finger, thumb and forearm. The position of the buttons provide for natural and comfortable movement of the hand while the belt clamp is being worn on a belt and forearm is extending in a downward direction.

A feature and advantage of embodiments is a compartment for containing the movable latching members formed by an extending portion of the outboard plate connected to a lower edge of the outboard plate by a living hinge. The extending portion configured as a cover shaped to fit into a compartment defining containment portion of the outboard plate.

Referring to FIGS. 1-4 and 7, in embodiments, a belt clamp 20 includes an inboard plate 22 and an outboard plate 24 that are pivotally coupled at their upper ends 26, 28. The belt clamp 20 also includes a spring biased locking mechanism 30 that selectively and releasably connects the lower end 32 of the inboard plate 22 to the lower end 34 of the outboard plate 24. A belt 43 may be clamped between the inboard plate 22 and the outboard plate 24 by placing the belt 43 between inboard plate 22 and the outboard plate 24 and locking the lower ends 32, 34 of the plates 22, 24 together using the locking mechanism 30, See FIG. 7. Outboard plate 24 may have features such as holes 86 for attachment of a holster or accessory.

In embodiments, the inboard plate 22 and an outboard plate 24 connected to the inboard plate 22 at an upper pivoting connection 38. Each plate 22, 24 comprising an upper hinge portion 40, 41; the upper hinge portions 40, 41 cooperating to form the upper pivoting connection 38 at an upper end 42 of the belt clamp 20. Each plate 22, 24 has interlaced knuckles 44. At least one of the inboard plate 22 and outboard plate 24 may have pins 48 that are unitary with the respective knuckles 44 of said plate to fit in the knuckle voids 50 of the knuckles 44 of the other plate 22, 24. As shown in FIG. 4, inboard plate 22 may have knuckles 44 having a C-shaped portion 44A.

Outboard plate 24 may have pins 48 that extend between and are unitary with respective knuckles 44. Each C-shaped portion 46 of inboard plate 22 mates with a portion of a pin 48 of outboard plate 24 and may be snapped into place. In embodiments, a ratio of the upper hinge portion 40, 41 width to the overall width of the belt clamp 20 is greater than 0.9. A detent feature, configured as a nub 51 may provide favored positions in the range of motion of the inboard plate 22 and outboard plate 24. The nub 51 can interface with a cooperating feature (not shown) on an adjacent knuckle 44 or can simply disengage the adjacent knuckle 44 at certain positions in the range of rotation of the inboard and outboard plates 22, 24 of the clamp 20.

Referring to FIGS. 3-6C, in embodiments, the locking mechanism 30 includes locking posts 52 on the inboard plate 22 that are displaced upwardly from the lower end 32 of inboard plate 22. Locking posts 52 cooperate with latching portions configured as latching members 54 with finger buttons 55. Latching members 54 are rotatably and slidably supported by the outboard plate 24 in a compartment 58 defined by a containment portion 60 of the outboard plate 24.

Latching members 54 are entirely contained within containment portion 60 with the exception of opposing finger buttons 55. A living hinge 61 connects an extension portion 62 to a lower margin 63 of the outboard plate 24. The extension portion 62 is configured as a compartment cover to fit into and close the compartment 58.
