| 20080202702 | Slat angle adjusting device for a venetian blind - A slat angle adjusting device for a venetian blind has a body, a drive device and an outer casing. The body is hollow and has a shell and a cover. The shell and the cover each have a mounting hole and a mounting recess. The drive device is rotatably mounted on the body and has a pinion, a rotating rod and a roller. The pinion is rotatably mounted in the mounting holes in the shell and the cover. The rotating rod is rotatably mounted in the mounting recesses of the shell and the cover and is engaged with the pinion. The roller is attached to the rotating rod and has a cord recess, a gap and a locking hole. The outer casing is detachably connected to the body and has a base and a protecting hood. | 08-28-2008 |
| 20080216966 | Manually Operated Venetian Blind and Method of Darkening a Room - In one embodiment, a manually operated internal Venetian blind for raising/lowering a plurality of slats is disclosed, and comprises a stationary bearing housing, a longitudinally displaceable bifurcated bearing block, a counterweight interconnected to the bearing block and housing at least one internal magnet, and a first linearly displaceable actuator disposed outwardly to one of two glass sheets and provided with at least one external magnet at a fixed distance from the internal magnet. The displacement of the first actuator is significantly less than the displacement of the longitudinally lowest slat due to the winding of central cords around a ball bearing housed within the bearing block. In another embodiment, a device for tilting the slats to which two outer cords are affixed is provided with two laterally oriented sides and an annular protrusion rotatably supported by a suitable assembly secured to a support surface and transversally extending outwardly from each laterally oriented side, such that the tilting device is rotatable about a transversal axis coincident with the axis of the annular protrusions. An external blind is also disclosed. | 09-11-2008 |
| 20080277075 | Window covering device - A window covering device without cord control comprising a top elongated member, a middle elongated member, a bottom elongated member, a window covering, a middle elongated member controller, a bottom elongated member controller, a window covering is connected between the middle elongated member and the bottom elongated member, the middle elongated member controller is mounted in the top elongated member, with a connection cord extending through the bottom elongated member, the window covering, the middle elongated member, and connected with the top elongated member. The window covering device can be opened from top or from bottom without cord control. | 11-13-2008 |
| 20080277076 | Window covering device - A window covering device has a top elongated member, a middle elongated member, and a bottom elongated member. A window covering is mounted between the middle elongated member and the bottom elongated member. A middle elongated member controller is mounted in the top elongated member, and is connected with the middle elongated member through the top elongated member by the connection cord. A bottom elongated member controller is mounted in the bottom elongated member, and is connected with the top elongated member through the bottom elongated member, the window covering and the middle elongated member by the connection cord. The middle elongated member controller has a cord seat with a spiral spring, the cord seat has connection cord, and connected with the middle elongated member through the top elongated member, in order to control the middle elongated member. | 11-13-2008 |

| 20140144596 | TWO-WAY UP-DOWN CURTAIN - A two-way up-down curtain includes a fixed top base including a device space and its bottom is drilled several eyelets. A coil rope control device is located in the device space is coiled with a first and a second thread. The threads penetrate through the eyelet in the bottom of the fixed top base. A curtain under the fixed top base includes a mobile top, a bottom and a curtain. The first thread penetrates through the mobile top, curtain and bottom downwards, and through the bottom downwards with an extended end. A pulling base is only fixed to the extended end of the first thread mutually, so that the user can push and pull the mobile top or the pulling base by hand to change the state of the curtain. The mobile top can be actually prevented from movina to result in clearance to the fixed top base. | 05-29-2014 |
