Abstract

An automated actuator is fabricated in kit form and adapted to be assembled and disassembled for use with sliding doors, windows or other similar panels. The actuator includes a support column which is adjustable to be braced at the existing door jamb at either side of the door frame to move the panel. Mounting of the actuator does not require the surrounding frame or wall structure to be structurally altered. Circuitry for the actuator ceases the sliding movement of the door when the door meets resistance, such as by a child or animal in the path of the door, and re-tests for the resistance to determine whether the door should continue along the intended path.

3. The apparatus according to claim 1, wherein the first assembly includes:

a support block adapted to brace the support member,

a threaded member extending from the support block and adapted to be received in the first end of the support member, and

an adjusting member adapted to be moved along the threaded member to a select position on the threaded member, wherein the first end of the support member abuts the adjusting member and any portion of the threaded member extending from the adjusting member is received in the first end of the support member, whereby the length of the support member is adjusted to brace the support member at a side of the passageway.

4. The apparatus according to claim 1, further including an engaging member for releasably engaging the first coupling member to the second coupling member.

5. The apparatus according to claim 1, wherein the first coupling member includes a first bracket, the first bracket having a first flange extending from the third assembly, the first flange having a first aperture extending therethrough, and the second coupling member includes a first surface and a second surface, the first surface including a second flange having a second aperture extending therethrough and a third flange having a third aperture extending therethrough, the second and third flanges of the second coupling member being spaced apart with the second and third apertures being in registration with each other, the second surface having an adhesive fastener disposed thereon for releasable engagement with the panel.

6. The apparatus according to claim 5, wherein the first flange of the first bracket is sized and shaped to be disposed between the second flange and the third flange of the second bracket, the first, second and third apertures in registration with each other.

7. The apparatus according to claim 6, further including a pin member sized and shaped to be removably inserted into the first, second and third apertures for releasably coupling the first flange of the first bracket between the second and third flanges of the second bracket.

8. The apparatus according to claim 1, wherein the first coupling member mounted to the endless flexible member of the third assembly comprises:

a crossbar member;

a shaft member having opposed ends and extending through the crossbar member;

a pair of rollers disposed on the shaft member for rotational movement and spaced apart at opposite sides of the crossbar member; and

a U-shaped bracket having opposed ends turned inward, each one of the opposed ends adapted to receive a corresponding one of the opposed ends of the shaft member, and a first surface facing the panel, the first surface having fastening material disposed thereon;

and the second coupling member includes a base plate having a first surface with a fastening material adapted for mating engagement with the fastening material disposed on the U-shaped bracket, and a second surface having an adhesive disposed thereon for releasable engagement with the panel.

9. The apparatus according to claim 1, wherein the third assembly is adapted to be flipped over for the end portion to be maintained in registration with the drive mechanism and permit the other end portion of the third assembly to extend in an opposite direction.

10. The apparatus according to claim 1, further including a wireless transmission signal device to actuate the apparatus.

11. The apparatus according to claim 1, further including pressure sensitive contact switches adapted for wireless transmission of signals to actuate the apparatus.

12. The apparatus according to claim 1, further including a proximity switch adapted to actuate the apparatus.
