| 20100154176 | LOCKING DEVICE - A locking device for temporary locking and securing of a chain, cable or wire, comprising a fork shaped main body ( | 06-24-2010 |
| 20120023710 | Trailer Hitch-Ball Chain Coupler - A tool for temporarily coupling a chain to a trailer hitch-ball or similar device, or for temporarily coupling separate chains comprising a rigid flat body contour plate with a hitch-ball cavity member for engagement with a trailer hitch-ball or similar device, an engagement slot member as a securing mechanism to the hitch-ball, and opposing chain link notches members for engagement of chain(s). | 02-02-2012 |
| 20120042481 | Cable slider with symmetric pieces - a device which can slide up and down on a chain or cable, can be loosened to attach to the chain or cable, but does not have any parts that come free when the part is loosened. | 02-23-2012 |
| 20100115735 | PULL HANDLE - A pull handle for operating a window covering with a pulling lead. The pull handle includes a first element with a top end and a bottom end, and a second element, attachable to the first element, with a top end and a bottom end. When the second element is attached to the first element, the pull handle is along a section of the pulling lead with the position of the pull handle fixed with respect to the pulling lead. The pull handle is configured to have a diameter that is easily and comfortably gripped by an operator. | 05-13-2010 |
| 20130247336 | ROLLER SHUTTER BEAD CHAIN CONNECTOR - A roller shutter bead chain connector includes a connector main body having an internal receiving space for receiving beads of the bead chain. Two engagement slots are formed at two ends of the connector main body. A string segment between two beads is engaged into the engagement slot to connect the connector main body with the bead chain for controlling the up and down movement of the roller shutter. The connection main body can be fitted on any section of the bead chain as necessary, whereby the connection main body can be stopped to locate the roller shutter curtain at a desired height. | 09-26-2013 |
| 20140359976 | CURTAIN PULL BEAD FIXING APPARATUS - The present invention discloses a curtain pull bead fixing apparatus, comprising a stationary seat, a bottom cover, a bead disk, a button, a spring, a main body, a slider and a front cover. One side of the stationary seat is assembled with the bottom cover, and the other side of the bottom cover is fixedly connected with the main body. The other side of the main body is fixedly connected with the front cover. A through hole is formed in the bottom cover for passage of the button, and the first end of the button is pressed against the stationary seat. The pull bead is in a tensioned state all the time and will not collide with the surface of the wall even under an external force. The children could not play with the pull bead by wrapping the same around their neck, which brings about high safety. | 12-11-2014 |
| 20150308471 | LOCKING TENSIONER FOR A ROLLER BLIND - A locking tensioner for a roller blind. The roller blind is of the type having a roller and a looped chain or cord to impart rotational movement to the roller. The locking tensioner comprises first and second members, each having a first end and a second end. The first ends have apertures dimensioned to receive therethrough the chain or cord of the roller blind. The first and second members are rotatably secured to one another and rotatable about an axis between a locked and an unlocked configuration. When the first and second members are in their unlocked configuration the apertures are aligned permitting the chain or cord to freely move through both of the apertures. When the members are in their locked configuration the apertures are at least partially misaligned restricting the movement of the chain or cord through the apertures. The locking tensioner includes a spring biasing the first and second members toward their locked configuration. | 10-29-2015 |
