Abstract

An improved housing arrangement is disclosed for a small, hand-held battery powered portable device which includes an associated battery compartment with integral battery door accessible from the side of the housing. The battery door and compartment are intercoupled by a non-destructive, breakaway hinge device which permits separation therebetween when the door is pivoted outwardly from the top beyond a set predetermined limit. It may be reattached simply and conveniently by a press fit. A latch mechanism is included integral with the surface of the battery door which may be operated by hand without special tools to latch and unlatch the door.

Claims

1. An improved housing arrangement for housing electrical components and having a non-destructive, breakaway battery door, comprising in combination:

a housing having top, bottom, front, back and side walls, said housing including a cavity for accomodating an associated cylindrical battery with an opening along one side of said housing giving access to said battery cavity;

a battery door panel interfitting in said battery cavity opening;

breakaway hinge means with respective portions intercoupling the bottom of said door panel and said housing to permit said door to pivot outwardly at the top thereof, said door when pivoted outwardly beyond a predetermined distance forcing disengagement of respective portions of said hinge means to non-destructively separate said door from said housing;

shoulder means mounted on said housing inside said battery cavity;

a cylindrical wing member integral to the interior side of said battery door panel into which a cylindrical battery is placed, said wing member including a door stop means which engages said shoulder means when said door panel is extended outwardly to a predetermined distance; and

latch means, integral with said battery door surface and operable in a lateral direction to releasably latch said battery door in said housing.

2. An improved housing arrangement in accordance with claim 1, wherein said breakaway hinge means includes a first cylindrical rod portion extending across the bottom of said cavity which is overfitted by a circular recess extending across the bottom edge of said door panel, said bottom door edge pivoting about said rod within set predetermined limits.

3. An improved housing arrangement in accordance with claim 1, wherein said battery door panel includes a battery holder for accepting and captivating an associated battery and wherein the pivoting of said battery door panel brings the battery into and out of said electrical contact within said battery cavity.

4. An improved housing arrangement in accordance with claim 1, wherein said battery door panel contains a vertically slidable latch means integral thereto which operates to secure the battery door panel to said housing by the associated movement of internal vertical projecting members which position themselves at a predetermined distance against the top shoulder of the inner battery cavity contained within the housing arrangement, in such a manner to thereby secure the battery door panel when in a latched position.
