Abstract

An apparatus 10 for replacing a battery 12 in a battery powered detection device 14 is disclosed. The apparatus 10 includes a battery housing 18 attached to the detection device 14 for receiving a battery 12 therein and structure for inserting and removing the battery 12 in the battery housing 18. The inserting and removing structure includes an elongated rod 20 and a battery carriage 22 attached to one end of the rod 20 for carrying a battery 12. The battery housing 18 presents a side opening 32 for receiving the battery carriage 22 for permitting a battery 12 to be attached to or removed from the battery connector 16.

Claims

1. An apparatus for replacing a battery in a battery powered device having a battery connector, the apparatus comprising:

a battery housing for receiving a battery therein, the battery housing presenting an upper end adjacent the battery connector, a lower end spaced from the device, and a side opening; and

means for inserting and removing the battery through the side opening of the battery housing, the means including

an elongated rod, and

a battery carriage having a lower end attached to one end of the rod, an upper end, and a battery-carrying chamber for carrying the battery, the battery carriage being adapted for sliding in and out of the side opening of the battery housing for permitting a battery to be inserted into and removed from the battery housing.

2. The apparatus as set forth in claim 1, the battery carriage including a base, a pair of upstanding, spaced-apart sidewalls an upstanding endwall, and an open endwall, the sidewalls and endwalls defining the battery-carrying chamber.

3. The apparatus as set forth in claim 2, the battery carriage further including a pair of retaining lips attached to the upper ends of the sidewalls, the retaining lips defining a slot therebetween extending across the upper end of the carriage between the endwall and the open endwall for exposing the terminals of the battery carried in the carriage, the slot permitting the battery terminals to be connected to the battery connector while the battery is in the carriage and permitting the carriage to be slid out of the side opening of the battery housing after the battery has been connected to the battery connector.

4. The apparatus as set forth in claim 3, the battery-carrying chamber presenting an interior size approximately equal to the size of the battery for securely retaining the battery therein for preventing the battery from shifting along the longitudinal axis of the carriage while the battery is being removed from the battery connector.

5. The apparatus as set forth in claim 3, the end wall presenting a hole therein for permitting a person'"'"'s finger to pass therethrough for dislodging a battery from the battery carriage.

6. The apparatus as set forth in claim 1, the battery housing including a pair of spaced-apart depending sidewalls, a depending endwall, and a bottom wall, the bottom wall presenting a slot extending between the endwall and the side opening for permitting the elongated rod to pass through the slot for permitting the battery carriage to slide in and out of the side opening of the battery housing.

7. A battery-operated device comprising:

a base for fastening to a ceiling;

electrical detecting means for detecting an environmental condition;

a battery connector fixed to the base and electrically coupled with the electrical detecting means;

a battery housing depending from the base for receiving a battery therein, the battery housing presenting an upper end adjacent the battery connector, a lower end spaced from the base, and a side opening; and

means for inserting and removing the battery in the battery housing, the means including

an elongated rod, and

a battery carriage having a lower end attached to one end of the rod, an upper end, and a battery-carrying chamber for carrying the battery, the battery carriage being adapted for sliding in and out of the side opening of the battery housing for permitting a battery to be inserted and removed from the battery connector.

8. The apparatus as set forth in claim 7, the battery carriage including a base, a pair of upstanding, spaced-apart sidewalls an upstanding endwall, and an open endwall, the sidewalls and endwalls defining the battery-carrying chamber.

9. The apparatus as set forth in claim 8, the battery carriage further including a pair of retaining lips attached to the upper ends of the sidewalls, the retaining lips defining a slot extending across the upper end of the carriage between the endwall and the open endwall for exposing the terminals of the battery carried in the carriage, the slot permitting the battery terminals to be connected to the battery connector while the battery is in the carriage and permitting the carriage to be moved out of the side opening of the battery housing after the battery has been connected to the battery connector.

10. The apparatus as set forth in claim 9, the battery-carrying chamber presenting an interior size approximately equal to the size of the battery for securely retaining the battery therein for preventing the battery from shifting along the longitudinal axis of the carriage while the battery is being removed from the battery connector.

11. The apparatus as set forth in claim 9, the endwall presenting a hole therein for permitting a person'"'"'s finger to pass therethrough for dislodging a battery from the battery carriage.

12. The apparatus as set forth in claim 7, the battery housing including a pair of spaced-apart depending sidewalls, a depending endwall, and a bottom wall, the bottom wall presenting a slot extending between the endwall and the side opening for permitting the elongated rod to pass through the slot for permitting the battery carriage to slide in and out of the side opening of the battery housing.
