Abstract: A latch system for a housing includes front and rear housing sections (204, 202) having a common side periphery (212) when assembled. The housing sections (204, 202) include wall segments (208, 206) projecting therefrom. Each wall segment (208, 206) has a locking side (214) adjacent and parallel to the common side periphery (212) and has a recess (402, 210) therein for mating with an elastomeric interlocking band (100). The elastomeric interlocking band (100) includes teeth (102, 103) projecting therefrom for engaging with the recesses (402, 210) in the wall segments (208, 206). To latch together the front and rear housing sections (204, 202) the elastomeric interlocking band (100) is slidably assembled onto the wall segments (208, 206) of a first housing section (204, 202) until the teeth (102, 103) engage with the recesses (402, 210) therein.

Abstract: A holster (100) for receiving a pager (220) having an protrusion (225) comprises a housing (105) having an interior surface (205) and an exterior surface (210), the interior surface (205) forming a cavity (215) for receiving the pager (220). A flexible arm (110) is affixed to the housing (105) and moves between a first position wherein the flexible arm (110) engages the pager protrusion (225) when the pager (220) is within the cavity (215) and a second position wherein the flexible arm (110) is deflected by the pager protrusion (225) as the pager (220) is inserted into or removed from the cavity (215). A belt clip (230) mounted to the housing (105) secures the holster (100) to an article. The belt clip (230) selectably contacts the flexible arm (110) and exerts a pressure thereto which increases the force needed to deflect the flexible arm (110) when the pager ( 220) is inserted into or removed from the cavity (215).

Abstract: A carrier (10) for receiving a portable product (20) having a protruding member (24) on at least one of the surfaces of the portable product comprises a housing (2) having a recessed area (4) and an aperture (19) therein having rails (13) therein and a removably insertable latch assembly for insertion into the aperture. The latch assembly comprises a flexible member (6) that allows the insertion of a portion of the latch assembly into the aperture and allows the mounting of the flexible member in the recessed area, a boss (3, 5, 7, & 8) having a ramp (8) and a notch (7) coupled to the flexible member for sliding the latch assembly on the rails, and a spring (9) coupled to the boss for biasing the latch assembly in a first position (FIG. 7 ) and allowing the latch assembly to travel to a second position (FIG.
