Abstract

To provide an intrusion detecting device of a type in which a battery for supplying an electric power to both of the main unit and the transmitter is provided in a unit holder for holding the main unit, including the detecting element, to thereby increase the overall electric power capacity needed in the intrusion detecting device as a whole and, also, replacement of those batteries can be accomplished easily, the intrusion detecting device includes a main unit (1) including a detecting element (30), a battery (Ba) detachably mounted on the main unit (1) for supplying an electric power to the main unit (1), and a power supply line (18) fitted to the main unit (1) for supplying an electric power to a wireless transmitter (11) for transmitting wireless an output signal of the main unit (1).

Claims

1. An intrusion detecting device comprising:

a main unit including a detecting element for detecting a human body;

a battery detachably mounted on the main unit for supplying an electric power to the main unit;

a power supply line for supplying an electric power from the battery to a wireless transmitter for transmitting wireless an output signal of the main unit, the wireless transmitter being adapted to be mounted on an outer surface of the main unit; and

a dummy battery having an electricallly insulating property, the dummy battery being adapted to be fitted to a battery mount of the transmitter together with the power supply line in place of a battery for the transmitter.

2. The intrusion detecting device as claimed in claim 1, in which the dummy battery has a length set to a value smaller than the battery of the transmitter.

3. The intrusion detecting device as claimed in claim 1, in which the dummy battery is telescopically expandable in a direction lengthwise thereof.

4. The intrusion detecting device as claimed in claim 1, in which the power supply line and the dummy battery are jointed together and is hence integrated with each other.

5. The intrusion detecting device as claimed in claim 1, in which a contact piece capable to be connected with a battery of the transmitter is fitted to the power supply line.

6. The intrusion detecting device as claimed in claim 1, further comprising a base body for detachably retaining the main unit and a lens detachably fitted to the base body for covering a front surface of the main unit.

7. The intrusion detecting device as claimed in claim 1, further comprising a battery box for holding the battery.

8. The intrusion detecting device as claimed in claim 7, in which the battery box is detachably mounted on a rear surface of the main unit.

9. The intrusion detecting device as claimed in claim 8, in which the transmitter is disposed on a rear surface of the main unit, and the battery box is positioned in side-by-side relation with the transmitter when at a first mounting position, but when at a second mounting position, defines a mounting space for the transmitter at a location spaced from the rear surface of the main unit, the mounting space being defined between the battery box and the rear surface.

10. The intrusion detecting device as claimed in claim 7, in which the main unit is provided with an engagement element and the battery box is provided with a to-be-engaged element engageable with the engagement element.

11. The intrusion detecting device as claimed in claim 7, in which the battery box is capable of accommodating a plurality of batteries of different diameters or lengths.

12. The intrusion detecting device as claimed in claim 11, in which the battery box comprises a spring element for applying a biasing force to the battery in a direction radially of such battery and a retaining piece for retaining the battery against the biasing force in a direction radially thereof.

13. The intrusion detecting device as claimed in claim 11, in which the battery box further comprises a repositionable contact holder, having a contact engageable with one of electrodes of the battery, for selectively fitted at one of a plurality of different positions in a direction lengthwise of the battery for accommodating one of batteries of different lengths.

14. The intrusion detecting device as claimed in claim 13, in which the repositionable contact holder comprises a contact member having the contact and an anchoring member for selectively engaging a battery receptacle of the battery box at one of the plurality of the different positions in the lengthwise direction.

15. The intrusion detecting device as claimed in claim 14, in which the anchoring member comprises a generally U-shaped plate member and includes an anchoring portion fitted to the repositionable contact holder, and a pair of legs extending from opposite ends of the anchoring portion in a direction perpendicular to the anchoring portion and in which each of the legs is formed with a hook portion at a free end thereof, the anchoring portion is positioned on a front surface side of the battery receptacle and the hook portion is engaged with a corner area in a rear surface of the battery receptacle.
