Abstract
A cabinet construction is disclosed featuring the utilization of spring-biased hinge pins for removably mounting one or more doors for swinging movement between cabinet storage compartment closed and open positions in combination with a security device for normally preventing access to such hinge pins for door removal purposes. The invention additionally features a novel door/hinge assembly.
Claims10
A cabinet comprising in combination:
- at least one storage compartment having an access opening vertically bounded by a pair of horizontally extending cabinet frame members, one of said frame members having the interior thereof accessible only from within said storage compartment;
- a door for closing said access opening;
- hinge means for mounting said door on said frame members for movement between access opening closed and open positions, said hinge means including upper and lower hinge means each comprising an aperture formed in one of said door and said frame members and a hinge pin carried by the other thereof and removably received within its associated aperture, characterized in that said one frame member is formed with one of said apertures and its associated hinge pin is received therewithin to removably position an inserted end thereof within said interior of said one frame member, is supported for axial sliding movements by said door and has associated therewith spring means for normally maintaining said inserted end within said interior of said one frame member;
- and
- means removably inserted within said interior of said one frame member from within said storage compartment only when said door is in open position for normally preventing unauthorized removal of said associated hinge pin from within said one of said apertures against the bias of said spring means.

A coin operated locker cabinet or the like comprising in combination:
- a cabinet frame including horizontally extending upper, lower and at least one intermediate frame member cooperating to vertically bound access openings of at least two vertically aligned storage compartments, one of said upper and lower frame members is provided with an aperture, the other of said upper and lower frame members carries a hinge pin, each said intermediate frame member having a through opening arranged in vertical alignment with said aperture and said hinge pin, and the one of said upper and lower frame members provided with said aperture having the interior thereof accessible through an adjacent storage compartment whose access opening it bounds;
- a plurality of releasably lockable doors associated one with each of said access openings of said storage compartments, each of said doors having means defining a pair of vertically aligned first and second bearing openings disposed on each door relatively adjacent said one and said other of said frame members, respectively, said first bearing openings slidably mounting hinge pins to alternately project through said through opening of an adjacent intermediate frame member for receipt within the second bearing opening of a next adjacent door or through said aperture for receipt within the interior of said one of said frame members, said first of said bearing openings having associated therewith stop means projecting thereinto and a spring arranged for end bearing engagement with said stop means and said hinge pin slidably received therewithin, said second bearing openings having stop means positioned therewithin for end engagement by a hinge pin slidably supported by the first bearing opening of a vertically adjacent door with the second bearing opening of the door immediately adjacent said other of said frame members receiving said hinge pin carried thereby;
- and
- means disposed within said interior of said one of said frame members for normally preventing manually induced movement from within said aperture of an inserted end of the hinge pin slidably received within said first of said bearing openings of an adjacent door, and the last said means is accessible through the storage compartment adjacent to said one of said frame members for permitting said movement only when the door associated with its access opening is in an open position.
