Abstract

Described is a floating hinge for securing a movable cover to a housing or the like. It is particularly suitable for attaching covers to back-lighted displays which utilize translucent display members. These display members must be accurately positioned with respect to the rear or back illuminating devices to reduce light loss and diffusion, both of which reduce legibility of the displayed data. Conventional hinges, due to manufacturing and assembly tolerances, will not provide sufficiently accurate positioning of the cover and the member.

Floating Hinge

Described is a floating hinge for securing a movable cover to a housing or the like. It is particularly suitable for attaching covers to back-lighted displays which utilize translucent display members. These display members must be accurately positioned with respect to the rear or back illuminating devices to reduce light loss and diffusion, both of which reduce legibility of the displayed data.

Conventional hinges, due to manufacturing and assembly tolerances, will not provide sufficiently accurate positioning of the cover and the member.

The complete hinge includes a fixed hinge support which is mounted in the bottom wall of the housing containing an illumination source. The fixed hinge support is provided with a pair of upright spaced members, only one of which is illustrated in Fig. 1. The spaced members each include, on their confronting surfaces, hinge pin journal grooves which are open to the rearward surface of the spaced members. In addition, the fixed hinge support is relieved in the area between the spaced members, to provide clearance for the movable portion of the hinge which is mounted on the cover.

The movable portion of the hinge includes a hinge pin which is supported in the hinge pin journals described above. The cover is assembled to a fixed support before the support is assembled into the housing. Two guides, only one of which is illustrated in Fig. 1, perform two functions. They guide along the front edge of the bottom wall of...
