| 20110167588 | SOFT-CLOSING DEVICE FOR A SLIDING DOOR - A soft-closing device has a base, a cylinder, a slider and a resilient member. The base has a track channel and at least one guiding channel. The cylinder is mounted in the base and has a housing and an expansion rod. The slider is mounted slidably in the track channel, is connected pivotally to the expansion rod and has two holding arms, a positioning pin and a holding recess defined between the holding arms. The positioning pin is mounted slidably in the at least one guiding channel. The resilient member has two ends connected respectively with the base and the slider. | 07-14-2011 |
| 20110025075 | WINDOW TILT LATCH - A window tilt latch has a casing, a latching bolt and a safety device. The latching bolt is mounted slidably in the casing and has a latching end, an inner end and a sliding element. The latching end extends out of the casing. The sliding element is mounted on the latching bolt and is mounted slidably in a guiding slot defined in the casing. The safety device is mounted on the casing and has a control knob mounted rotatably on the casing, selectively abuts with the inner end of the latching bolt to keep the latching bolt from being retracted into the casing. The control knob has an inserting hole selectively aligning with the inner end of the latching bolt to allow the inner end of the latching bolt to be inserted into the inserting hole and to retract the latching bolt into the casing. | 02-03-2011 |
| 20100275410 | AUTOMATIC POSITIONING HINGE - A positioning hinge has a body, a pivotal shaft, a securing base and an automatic closing device. The pivotal shaft is mounted in the body and has at least one positioning face defined in the pivotal shaft. The securing base is connected pivotally to the body with the pivotal shaft. The automatic closing device is connected to the pivotal shaft and has at least one cylinder provided with pressured air. The at least one cylinder connects to and pushes the at least one positioning face on the pivotal shaft to provide an automatic closing force to the door panel with the pressured air when the pressured air in the at least one cylinder is compressed. Accordingly, the positioning hinge can automatically close a door panel slowly and smoothly with the pneumatic pressures provided by the cylinders. | 11-04-2010 |
| 20100205880 | RAIL ASSEMBLY FOR A GLASS DOOR - A rail assembly for a glass door has a rail body, two clamping members, a pushing member and at least one pushing bolt. The rail body has a clamping channel defined in and along the rail body. The clamping members are movably mounted in the clamping channel. Each clamping member has a clamping recess and an inclined guiding surface. The clamping recess is defined in the clamping member at a side facing to the other clamping member. The inclined guiding surface is defined in the clamping member at a side opposite to the other clamping member. The pushing member is mounted movably in the clamping channel, holding the ends of the clamping members inside and has two inclined surfaces abutting respectively with the guiding surfaces of the clamping members. The least one pushing bolt is screwed into the rail body and pushes against the pushing member. | 08-19-2010 |
| 20090183539 | LOCK ASSEMBLY - A lock assembly has a body, a locking cylinder, a latching device, a linking device and a locking mechanism. The locking cylinder has a pushing lug. The linking device is connected to and driven by the latching device. The locking mechanism is driven by the pushing lug of the locking cylinder and has a bolt base, a pushing arm and a locking bolt. The bolt base is mounted slidably in the body and has an edge pushed by the pushing lug on the locking cylinder and a limiting tab. The locking bolt is slidably mounted on the bolt base and abuts with the limiting tab on the bolt base when the locking bolt retracts completely into or extends out from the body. The locking bolt has a blocking tab selectively blocks the linking device. | 07-23-2009 |
