Abstract

Abstract An improved battery door structure is provided which has advantageous use in compact electronic apparatus, as for example a hearing aid, electronic watch, miniature calculator and other types of small battery operated devices. The structure includes a body member including a power source, such as a small battery. The structure is provided with a battery receptacle which has a hinged door, which may be opened and closed at will from the outside of the body member. In one preferred embodiment, the body member may be readily removable and replaceable from the remainder of the structure. The body member as a unit is provided with plastic members forming plastic hinge means for the battery door. The battery door includes hinge pivot pin means wherein the door and hinge pivot means preferably are molded as one piece.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 111 words
Compact electronic apparatus including a molded plastic body member, a chamber in said body member for receiving a battery and a door for opening and closing the battery chamber, hinge means provided at one side of said door; said hinge means comprising hinge pin means formed of plastic material, and plastic hinge pin support members for the hinge pin means formed in the plastic material of said body member at opposite sides of said chamber and being dimensioned with respect to the hinge pin means so that the hinge pin means may be snapped into the support members due to the resiliency of the plastic material from which they are formed.
