Abstract
An improved system utilizes a series of structures which permit magnetic closure to be used in existing carriers and components. Magnetic support structures include members which ride in the carrier, as well as special size members which mount in the lead or wand carrier and which reside in the vertical blind track end caps. All of the structures are installable as retro-fit and which can work with existing tracks, carriers and end caps, even though these structures have been optimized for small size.
Claims12
A positive closure system for a vertical blind comprising:
- an elongate track;
- a rotatable rod rotationally supported by said elongate track;
- a lead carrier having a wand for manual turning input and an internal fitting for translating manual turning input into rotation of said rotatable rod;
- a plurality of follower carriers each having an internal rotatable sleeve engaging said rotatable rod, and a rotatable blind support linked to turn in response to rotation of said rotatable rod;
- a magnetically attractable plate having a vertical surface and attached to said lead carrier;
- a magnetically attractable screw extending from said lead carrier;
- an end cap secured by said elongate track;
- a first flat member attached to said end cap and carrying a first magnet and having a first aperture surrounding said rotatable rod and a second aperture;
- at least one second flat member having a first aperture surrounding said rotatable rod, a second aperture and a second magnet, and movable to a position adjacent said first flat member;
- and wherein said magnetically attractable screw extends through said second aperture of said at least one second flat member engaging with said first magnet, and wherein said second magnet engages said magnetically attractable plate when said lead carrier is brought sufficiently close to said end cap to hold said lead carrier positively adjacent said end cap.
