Abstract

A motion-trip security device, for transmitting, receiving, and signalling upon occurrence of a breach of security of the object to which the device is affixed, said device being automatically operative on slight unauthorized movement of the object or of the device, and having selective transmitting and receiving features to indicate which of a series of such objects is being moved.

Claims

1. A motion-trip security device for sending and receiving a signal upon movement of the object to which the device is affixed, comprising:

a. a motion-activated switch including a ring-shaped horizontally orientable contact member and a vertically orientable flexible weighted conductor extending linearly through said ring and out of contact with said ring when said contact member and said conductor are respectively oriented in horizontal and vertical positions, said switch being closed by contact of said conductor with said member in consequence of movement of said object effecting flexing of said conductor against said ring;

b. a transmitter electrically connected for sending of a signal upon closing of said switch;

c. container means for said switch and transmitter;

d. support bracket Means attached to said object;

e. swivel and socket interconnection means attached between said bracket means and said container means, and adapted to permit universal rotation of said container means whereby to enable orientation of said container means to place said contact member and flexible conductor in said horizontal and vertical positions;

f. a level indicator on said container adapted to indicate when both said contact member and said conductor are oriented in said horizontal and vertical positions; and

g. signal-receiving means for receiving signals from said transmitter, indicating breach of security.

2. Apparatus in accordance with claim 1 further including locking means for locking said container means in said oriented position.

3. Apparatus in accordance with claim 2 wherein said interconnection means carries a tongue plate having a turnedover end portion adapted to frictionally engage a flattened portion of said bracket, said end portion including a raised boss which snap locks into engagement with an aperture in said flattened portion of said bracket, the resulting engagement being such that a substantial force and tilting motion is required to disengage said bracket and tongue plate, whereby any attempt to do so will disturb said switch and activate said transmitter.

4. In a motion-trip security device as described in claim 1, said signal-receiving means comprising:

a. a receiver panel, b. identification positions on said receiver panel, identifying the object to which said signal sending means is affixed, c. indicator means, adjacent each of said indicator positions, for signalling a breach of security as to a particular object, and d. switch means associated with each of said identification positions for rendering said receiving member operable with respect to the object to be checked for movement.
