| 20090020239 | Self-raising window covering - The present invention relates to a self-raising window covering and a control mechanism for the window covering. In particular, the window covering includes a drive unit, such as constant force spring, that is adapted to apply a substantially constant rotational force on the drive axle. A cord winding assembly is coaxially mounted on the drive axle, and includes at least one winding drum operatively connected to a second end of the raising cord and having a tapered portion, as well as a rotatable positioning member for moving the cord winding assembly laterally along the drive axle upon rotation of the positioning member. The cord winding assembly is adapted to translate the rotational force on the drive axle to a raising force on the raising cord, wherein the raising force is greater than a downward force exerted by the shade element and bottom rail throughout the range of opening and closing. A clutch member or locking member is also operatively connected with the axle and adapted to releasably lock the drive axle in a desired position. | 01-22-2009 |

| 20100031481 | SAFE PACIFIER CLIP - The present invention relates to a safe pacifier clip, mainly composed by a base sheet, a pulling member, a latching member and a tying tool. When a sheet button of the pulling member is pulled, the sheet tenon is rotated in the tenon slot provided at the inner wall of the retaining sheet, and the pressing section provided behind the sheet tenon is optionally moved to the tilting section or the plane section that has a height difference with respect to the height of the tilting section, and the resilient tenon provided against the bottom surface of the convex edge is driven to release or store energy by the latching member according to the height difference between the plane section and the tilting section, and the other end of the clip sheet is driven to be outwardly pulled or inwardly fallen by the latching member around the axial core defined by the connecting location where the latching member and the retaining sheet are pivotally connected, so a gap or an engaging status is formed between the clip teeth and the sheet teeth. | 02-11-2010 |
| 20100313390 | SAFE PACIFIER CLIP - The present invention relates to a safe pacifier clip, consists of a base sheet, a pulling member, a latching member, a clamping member and a tying tool. A connecting sheet is longitudinally connected between two protruding sheet columns and the height of the connecting sheet is lower than that of the sheet columns, a first flange is installed on the top end of the connecting sheet; a second flange provided on the top end of the latching member is installed in the connecting sheet and is provided adjacent to the inner surface of the first flange; an opening at the bottom end of the cap-shaped clamping member is provided to the first and the second flanges that are in a stacking status, and arc-shaped clamping sheets provided at the front and the rear ends of the clamping member clamp the two flanges. When the sheet button at the top end of the pulling member is pulled, the pressing sheet of the sheet tenon is optionally moved and positioned at a top or a bottom oblique surfaces of the block, and the two arc-shaped clamping sheets connected to the two flanges release or store energy, so the clamping sheet at the other end of the latching member is outwardly raised or inwardly clamped. The present invention has advantages of preventing components from being broken and complying with safety regulation established by various countries, and suitable to be used on an infant without safety consideration. | 12-16-2010 |
