A hinge device comprising a main body in the form of a channel member, a mount pin projecting outward from the web of the main body, and a pressing plate pivoted at its one end to the inner side of one side wall of the main body and retractable into the channel of the main body, the pressing plate being provided with a wedge formation on one side surface thereof opposed to said one side wall of the main body so as to gradually approach the other side wall of the main body as the pressing plate is retracted into the channel of the main body. A plate, such as the closure plate of a cabinet, can be loosely fitted into the channel of the main body with the pressing plate withdrawn therefrom and can be tightly held in the channel by the wedging effect produced when the pressing plate is retracted. The hinge device can be installed in place easily and yet holds the plate reliably.
A hinge device comprising a main body in the form of a channel member having two parallel side walls and a web connecting said side walls, a mount pin projecting outward from said web, and a pressing plate having oppositely facing side surfaces, said pressing plate being connected adjacent to one of its ends to one of said side walls by an axially slidable pivot and being pivotally retractable into said channel member between said side walls, said pressing plate being provided with a wedge formation on the one of said side surfaces opposed to said one side wall, the other of said side surfaces of the pressing plates being planar and parallel to the other side wall of said channel member, said wedge formation being adapted in response to pivotal retraction of said pressing plate into said channel member to coact with said one side wall and translate said pressing plate toward the other side wall of said channel member, said other planar side surface of said pressing plate gradually approaching said other side wall in subtantially parallel relation therewith.
