Abstract

A decorative housing for a fire extinguisher. A five sided box forms a cavity to receive and hold a fire extinguisher. A door or decorative cover is slidably mounted to the box adjacent the cavity and is movable from an up position closing the cavity and concealing the fire extinguisher to a down position revealing the fire extinguisher. A heat and smoke detector mounted to a clock frame above the box is connected to a source of electrical energy and in turn to a solenoid. The plunger of the solenoid normally extends into the door locking the door in the closed position. Activation of the detector withdraws the plunger allowing the door to slide downwardly. An audio alarm and light within the box cavity activate simultaneously upon the withdrawal of the plunger. A cord is connected to the plunger to allow manual withdrawal of the plunger and opening of the door.

Claims

1. A combination clock and fire extinguisher apparatus comprising:

a housing mountable to a wall and having a cavity with a vertical opening sized to receive and hold a fire extinguisher;

a fire extinguisher positioned within said cavity but removable therefrom;

a door slidably mounted to said housing adjacent said vertical opening and movable by the force of gravity from an up position closing said cavity to a down position opening said cavity and revealing said fire extinguisher;

detection means operable to detect fire and to then produce a signal;

holding means on said housing operable to hold said door in said up position and to release same upon receipt of said signal allowing said door to fall to said down position;

a housing extension cantileveredly mounted to said housing and extending thereabove being spaced apart from said wall forming a recess therebetween;

a clock mounted to said extension;

a spacer mounted to said extension and extending rearwardly through said recess against said wall, said spacer having a vertical hole extending therethrough;

a pull ring and cord connected to said holding means to allow manual activation of same allowing said door to fall to said down position, said cord extending through said hole of said spacer and then through said recess and into said cavity to said holding means, said pole ring resting atop said spacer and concealed with said cord by said housing extension.

2. The apparatus of claim 1 wherein:

said door has a plunger hole and

said holding means has a solenoid electrically connected to said detection means which includes a retractable plunger extending lockingly into said plunger hole of said door when in said up position, said plunger being retractable by said solenoid automatically upon said detection means detecting a fire, said plunger having an inner end connected to said cord allowing for the retraction of said plunger when said pull ring is pulled upwardly, said plunger further having an outer end with a downwardly facing beveled surface contacting said door as said door is moved to the up position depressing said plunger until said outer end is aligned with said plunger hole, said housing includes a five sided box forming said cavity with said solenoid positioned at the highest position possible within said cavity.

3. The apparatus of claim 2 wherein:

said housing has vertically extending channels and said door has ridges extending into said channels guiding said door as the door moves from an up position to a down position, said channels and ridges include stop surfaces to limit travel of said door.

4. The enclosure of claim 3 wherein said housing includes an opening extending into said cavity and a pulley wheel mounted within said cavity adjacent said opening, said cord extends through said opening partially around said wheel to said plunger, said door includes an outwardly opening recess and a mirror mounted within said recess.
