A novel backpack frame having a pair of top end segments, a pair of stabilizing paddles, and a pair of vertical support members are disclosed. Also disclosed is a novel waist belt base and a removable waist belt that may be used with the backpack frame.
A buckle has two identical components relatively shiftable along a central axis into and out of an assembled state, with an interlocking mechanism for releasably coupling the components in their assembled state. The interlocking mechanism includes a wing on each of the components. The wings have opposed mutually spaced resilient panels defining passages therebetween leading to aligned locking surfaces. Each component also has a prong with oppositely protruding posts and first and second cam surfaces. The first cam surfaces are configured and arranged to urge the panels apart and thereby accommodate insertion of the prongs into the passages to locked positions at which the posts are in snap engagement with the locking surfaces. The second cam surfaces are configured and arranged to act in response to flexure of the prongs towards the central axis to urge the panels apart and to thereby accommodate withdrawal of the prong from the passages.

A quick release device for preventing unintended withdrawal of a handgun from a holster comprises a generally U-shaped hood with mutually spaced legs spanned by a bridge. The legs are arranged to straddle the holster, with the hood being rotatable about a fixed first axis between a rearward position at which the bridge overlies the holster opening, and a forward position at which the bridge is removed from the holster opening. At least one interior side plate is fixed with respect to the holster at a location adjacent to one of the hood legs. The interior side plate defines a guide path bordered by and extending forwardly from a locking notch. A trigger plate is connected to the hood leg for rotation about a second axis parallel to the first axis. The trigger plate is rotatable about the second axis to disengage the boss from the locking notch, thereby freeing the boss for movement along the guide path as the hood is rotated about the first axis from its rearward position to its forward position.
A modular articulated guide assembly comprises a series of guide lugs disposed transversely relative to a longitudinal axis of flexure of the chute. The guide lugs have generally U-shaped bodies with laterally spaced side walls joined by bottom walls to define guide channels. Centerline tabs project forwardly from the bottom walls, with each centerline tab being slidably received in a central recess in the bottom wall of an adjacent guide lug. The centerline tabs are in an abutting relationship when the guide assembly is retracted on its axis of flexure, and are adapted to slide in their respective central recesses and to move apart when the guide assembly is extended along or flexed from its axis of flexure. The guide lugs are interlocked in a manner permitting their limited movement to accommodate extension and flexture of the guide assembly.
A quick release device for preventing unwarranted withdrawal of a hand gun from a holster, comprising a thumb actuated hood translatably fixed with respect to and rotatable about a fixed axis between a rearward position overlying the holster opening and a forward position removed therefrom.
A backpack from has a forwardly facing side and a back side. The frame comprises a base having a generally flat midsection with forwardly curved end sections. A pair of mutually spaced arms project from the end sections of the base. The arms have a degree of twist that gradually diminishes from the end sections of the base to the upper distal ends of the arms.
A backpack comprises a load carrying section with a forwardly facing front panel. A pair of mutually spaced sleeves are joined to and border the sides of the front panel. An injection molded generally U-shaped partial perimeter frame has a base bordering a bottom of the front panel, with arms projecting from the base and into the sleeves on the sides of the panel. The load carrying section of the backpack is comprised principally of fabric. The front panel is flexible and has a stiffness greater than the stiffness of the fabric forming other portions of the backpack. In one embodiment, the front panel is integrally stiffened. In another embodiment, the front panel forms a pocket configured and dimensioned to accept a flexible stiffening plate.
A pocket for an article having oppositely facing sides, comprising a front component cooperating in a nested relationship with a back component to define a chamber having an open upper end sized to receive the article. The front and back components, when in their nested relationship, having confronting front and back walls and overlapping bottom walls closing the lower end of the chamber. The bottom walls are interconnected in a manner accommodating movement of the front component relative to the back component between a closed position at which the sides of an article received in the chamber via the open upper end are tightly confined between the front and back walls, and a release position at which the front wall is deflected away from the back wall to accommodate removal of the article from the chamber via the open upper end. A back mounting bar extends across and cooperates in spaced relationship with the exterior of the back wall to define parallel back channels. A pair of flexible mounting straps have lower ends and upper ends joined by a transverse web. The mounting straps extend downwardly through the back channels along the exterior of the back wall. The lower ends of the mounting straps are detachably connected to one of the bottom walls. The mounting straps cooperate with the exterior of the back wall to define a belt receiving slot.
A backpack frame has a front side and a back side and comprises generally parallel base and top sections that extend transversely across and are spaces one from the other along a center line of the frame. Side rails connect the base section to the top section. The side rails are arranged on opposite sides of the frame center line, and a stabilizing rib interconnects the side rails and extends transversely across the center line at an intermediate location between the base and top sections. The side rails converge inwardly from the base section towards the frame center line to the stabilizing rib, and diverge outwardly from the stabilizing rib and away from the center line to the top section.
A pocket comprises an inner cup cooperating in a nested relationship with an outer cup to define a chamber having a closed bottom end and an open upper end sized to receive an article. A hinge interconnects the inner and outer cups at the closed bottom end of the chamber. The hinge is configured to accommodate swinging movement of the outer cup relative to the inner cup between a closed position at which the sides of the article received in the chamber are tightly confined between opposite interior surfaces of the inner and outer cups, and a release position deflected outwardly from the closed position to accommodate removal of the article from the chamber via its open upper end.
A backpack frame comprises side rails defining a first profile. The first profile has a flat first base segment lying on a first reference plane, and a first concave segment leading from the first base segment to an upper end of the frame, with the first concave segment being spaced a maximum distance from the first reference plane at a first location between the first base segment and the upper end of the frame. An intermediate structure interconnects the side rails. The intermediate structure defines a second profile having a second flat base segment lying on a second reference plane parallel to the first reference plane, and a second concave segment leading from the second base segment to the upper end of the frame, with the second concave segment being spaced a maximum distance from the second reference plane at a second location between the second base segment and the upper end of the frame. The first and second locations are offset from one another.
