Abstract
A magnetic catch is used on coverings for architectural openings to releasably retain the coverings in an extended position and immediately adjacent to the framework of the opening. Magnetic components are installed on the covering and the framework surrounding at least part of the architectural opening. The covering is then placed in a position such that the magnetic components on the covering and the framework are close enough to attract each other through their respective magnetic forces. The magnetic forces work to releasably hold the covering in position relative to the framework.
Claims12
A combination of a covering for an architectural opening and a framework comprising in combination:
- a framework extending at least partially around said architectural opening;
- a retractable covering adapted to extend across said opening or be retracted adjacent to one side of said opening, said covering including a rail along a side edge thereof adapted to be positioned adjacent to a side of said opening opposite said one side of said opening when the covering is extended;
- and an adjustable system for attracting said rail to said opposite side of said opening, said adjustable system including a first magnetic component secured to said framework at a predetermined position adjacent to said opposite side of said opening and a second magnetic component positionable adjacent to said first mentioned magnetic component on said rail such that the magnetic components will attract each other to releasably retain said rail adjacent to said magnetic component in the framework, and an adjustable element for adjusting the spacing between said first and second magnetic components.
A combination of a covering for an architectural opening and a framework comprising in combination:
- a framework extending at least partially around said architectural opening;
- a magnetic component secured to said framework at a predetermined location, and
- a retractable covering adapted to extend across said opening or be retracted adjacent to one side of said opening, said covering including a rail along a side edge thereof adapted to be positioned adjacent to a side of said opening opposite said one side of said opening when the covering is extended, said rail having a second magnetic component positionable adjacent to said first-mentioned magnetic component on said framework such that the magnetic components will attract each other to releasably retain said rail adjacent to said magnetic component in the framework, said rail having opposite ends positionable adjacent to said framework and wherein there are two of said second magnetic components embedded one in each end of the rail with the rail being hollow and further including end caps positioned in its opposite ends with the second magnetic components being embedded in said end caps and wherein the magnetic components are metallic fasteners threadedly received in said end caps.
