Total Claims: 7
Claim 1
Independent Claim
146 words
A device for controlling operation of a pair of windows suspended by a trolley and adapted to be moved to and fro, above a coutertop comprising a magnetic pad secured to the bottom of each window and positioned above the top surface of the countertop, and magnetic means disposed below said countertop and adapted to coact with said magnetic pads for opening and closing said windows and control means for controlling the actuation of said magnetic means, wherein said magnetic means comprises a longitudinal support member, a sprocket rotatably supported at each end of said support member, and endless belt extending across said sprockets, a plurality of lower magnetic pads supported on said belt, each of said lower magnetic pads being disposed below a respective window magnetic pad, a motor for driving one of said sprockets, and brackets for securing said support member underneath said countertop.
Claim 2
Independent Claim
146 words
A device for controlling operation of a pair of windows suspended by a trolley and adapted to be moved to and fro, above a coutertop comprising a magnetic pad secured to the bottom of each window and positioned above the top surface of the countertop, and magnetic means disposed below said countertop and adapted to coact with said magnetic pads for opening and closing said windows and control means for controlling the actuation of said magnetic means, wherein said magnetic means comprises a longitudinal support member, a sprocket rotatably supported at each end of said support member, and endless belt extending across said sprockets, a plurality of lower magnetic pads supported on said belt, each of said lower magnetic pads being disposed below a respective window magnetic pad, a motor for driving one of said sprockets, and brackets for securing said support member underneath said countertop.
Claim 3
Dependent Claim
89 words
A device according to claim 1, wherein said control means includes a motor control, a pair of spaced limit switches mounted on said support member along a path travelled by said endless belt, means connecting a motor and said limit switches to said motor control and a control switch connected to said motor control for initiating the operation of said motor control, whereby, upon limitation, the motor is energized to move the lower magnetic pads and the attracted window magnetic parts to effect opening and closing of said windows.
Claim 4
Dependent Claim
23 words
A device according to claim 2, wherein the limit switches are spaced along the travel path of one of the lower magnetic pads.
Claim 5
Dependent Claim
69 words
A device according to claim 1, wherein the bottom of each window is provided with a longitudinally extending groove, both of said grooves defining an elongated channel defined by a pair of spaced walls of each window, one of said window magnetic pads being located adjacent one of said walls of one window while the other window magnetic pad is located adjacent the other wall of the other window.
Claim 6
Dependent Claim
60 words
A device according to claim 1, wherein said belt has a plurality of spaced apertures extending along the length of said belt, said sprockets being provided with teeth for engaging said apertures, said lower magnetic pads being provided with nibs engageable with some of the apertures, whereby said lower magnetic pads may be adjustably positioned with respect to said belt.
Claim 7
Dependent Claim
50 words
A device according to claim 1, wherein said endless belt has a pair of spaced opposite runs, one of said lower magnetic pads being secured on the inside of one of said runs, and the other lower magnetic pads being secured on the inside of the other of said runs.
