Abstract

A security spacer member (10) is provided for a security window (100) having a magnet (106) retained within its frame (104) and a magnet (110) retained within its sash (112) such that the two magnets (106, 110) mate upon closing of the security window (100) to maintain a security measure, such as an alarm, in a deactivated state. The security spacer member (10) has a shank portion (12) having first and second ends (14, 16) and one of the ends houses a magnet (30). In use, the security spacer member (10) is placed so as to prop open the security window (100), and the magnet (30) housed in the security spacer member (10) is positioned to mate with the magnet (106) in the frame (104) in order to maintain the security measure on its deactivated state despite the fact that the security window (100) is open.

Claims

1. A spacer member, in combination with a security window having a frame magnet and a window magnet capable of mating or abutting, the frame magnet communicating with a circuit that is capable of activating a security measure, whereby the mating of the frame and window magnets ensures that the security measure will not be activated by the circuit, while the disjoining of the magnet causes the security measure to be activated, said spacer member comprising:

a shank portion with a first end and a second end;

a spacer magnet retained within said first end, said magnet capable of mating with the frame magnet to ensure that the security measure is not activated, and said second end serving to wedgingly engage the security window whereby the security measure is activated upon attempted unauthorized entry by further raising the window or otherwise displacing the spacer member.

2. The combination of claim 1, wherein said spacer member further comprises:

a magnet assembly retained within said first end and removably receiving said spacer magnet.

3. The combination according to claim 2, wherein said magnet assembly comprises:

a housing having an insert portion for receipt in said first end of said spacer portion a flange for maintaining said magnet assembly at said first end, and an aperture for removably receiving said spacer magnet; and

a casing associated with said spacer magnet.

4. The combination according to claim 1, wherein said shank portion is capable of responding to the weight of the sash and window pane of the security window.

5. The combination according to claim 4, wherein said shank portion comprises two telescoping portions.

6. The combination according to claim 5 wherein said shank portion comprises a first telescoping shank portion;

a second telescoping shank portion fitting at least partially within said first telescoping shank portion; and

a resilient member serving to hold said first and second telescoping shank portions in longitudinal relation and allowing said first and second telescoping shank portions to move relative to each other.
