Wireless security sensor systems for windows and doors
First Claim
1. A wireless security sensor system, comprising:
- a window frame formed of an extrusion, said window frame having an exterior surface and an interior surface with a hollow interior therebetween defining a window opening;
a window sash in the window opening, the window sash having a peripheral exterior surface and being movable relative to the window frame between open and closed positions;
a sensor unit having a first end embedded within the frame, wherein the sensor unit is positioned within the hollow interior, and the sensor unit further includes a second end opposite from the first end, the second end facing the opening and being generally flush with the interior surface of the frame;
the sensor unit including an antenna extending along the hollow interior of the extrusion, a sensor switch, a microprocessor, a wireless transmitter and a power source; and
the wireless security sensor system including a magnet assembly mounted within the window sash for actuating the sensor switch, said magnet assembly including a first end that is embedded within the sash and a second end that faces toward the second end of the sensor unit when the window sash is moved into the closed position relative to the window frame, said second end being generally flush with the peripheral exterior surface of the sash.

Abstract
An wireless security sensor system includes a window frame defining a window opening, a window sash movable relative to the window frame between open and closed positions; and a sensor unit embedded in the window frame. The sensor unit includes a housing having an inner end within the window frame, an outer end at a surface of the window frame and a flexible ¼ wave wire antenna extending e.g. longitudinally of the window frame from the housing. The housing contains a sensor switch, a microprocessor, and RF transmitter and a battery for emitting signals to a master station or controller and the wireless security sensor system includes a magnet mounted in the window sash for actuating the sensor switch. The window frame is made from a plastics material extrusion having a hollow interior and the housing has a peripheral flange at the outer end thereof which is seated on the surface of the window frame.

4. A wireless security sensor system, comprising:
-
a window frame having an exterior surface and an interior surface with a hollow interior therebetween defining a window opening;
a window sash having a peripheral exterior surface within the window opening, the window sash being movable relative to the window frame between open and closed positions;
a sensor unit having a first end embedded within either the window frame or the window sash and a second end of the sensor unit opposite from the first end, the second end facing the opening such that the second end is nearly flush with its respective interior surface of the frame or peripheral exterior surface of the sash relative to the adjacent opening;
the sensor unit including an antenna, a sensor switch, a microprocessor, a wireless transmitter and a power source; and
the wireless security sensor system including a magnet assembly for actuating the sensor switch mounted within the window sash or window frame that does not contain the sensor, said magnet assembly further includes an end surface that is exposed to the opening and is aligned with the second end of the sensor unit when the sash is moved relative to the window frame in the opened position and that such end surface of the magnet assembly is nearly flush with respective peripheral exterior surface of the sash or the interior surface of the frame.

5. A wireless security sensor system, comprising:
-
a pair of members;
the members comprising a frame having a first exterior surface and second interior surface with a hollow interior therebetween defining an opening and a closure having a peripheral exterior surface movable relative to the frame between open and closed positions, the closure closing the opening in the closed position;
a sensor unit embedded in the hollow interior of the frame;
the sensor unit including a housing and the housing having an inner end thereof within the hollow interior of the frame and an outer end thereof facing the opening, said outer end being oriented toward the opening and terminates near the second interior surface such that the outer end is nearly flush with the second interior surface;
the sensor unit further including an antenna extending from the housing along the hollow interior of the frame;
the housing containing a sensor switch, a microprocessor, a wireless transmitter connected to the antenna and a power source; and
a magnet assembly having a first end and a second end mounted in the closure for actuating the sensor switch;
said first end of the magnet assembly being embedded within the closure with the second end oriented toward the opening and nearly flush with peripheral exterior surface;
wherein the outer end of the sensor housing embedded in the frame and the second end of the magnet assembly embedded in the closure are facing each other when the closure closes the opening. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
