20100051211 | Partition System - A partition system for office or room includes a first and second partition wall, a pivot mechanism connected between the partition walls and a glide set mounted on the bottom of the partition walls. The pivot mechanism can allow the partition walls to relatively rotate. The glide set is composed of a pair of inverted vee feet and a support mechanism. The feet have flexibility for matching uneven surface. The support mechanism can rotate the feet to be parallel with the partition wall for easy storage. | 03-04-2010 |

20090000750 | Portable wall-partition - Disclosed is a portable wall-partition that includes a plurality of panels and at least one hinge that connects each of the plurality of panels to a neighboring panel. A foot is positioned on a lower edge of each of the plurality of panels. The foot includes a first extension and a second extension. Each of the extensions includes a distal end thereof. The first and the second extensions are connected to each other at a proximal end (opposite the end having a wheel) to form a vertex. The foot also includes a spring located at or near the vertex. The spring biases the first and the second extensions toward each other. | 01-01-2009 |

20090087251 | TELESCOPIC DEVICE - A telescopic device includes an outer tube, an inner tube, a sustaining rod, an elastic body, and a locking device. The outer tube receives the inner tube for axial traveling. A positioning portion is formed opposite to the locking device on the inner tube, the inner tube is free to axially travel inside the outer tube and only stopped by the engagement of the locking device and the positioning portion. The sustaining rod is arranged inside the outer tube, an end thereof is fixed to a retaining seat of the outer tube and another end serves to sustain the elastic body. The elastic body is arranged inside the inner tube, the two ends thereof are fixed to the opposite sides of an end of the inner tube. | 04-02-2009 |

20110181090 | ROTARY ELBOW WITH DOUBLE SHAFT - A chair elbow capable of rotating with double shaft is disclosed. Two bearings are disposed on a mount board fixed on a chair. Each of the bearings connects one end of each of two rotating plates, while the other ends thereof are pivotally connected in a linear slot of a seat plate used for securing an armrest. The length of the slot is longer than the distance between the two bearings, and the latter is longer than the length of the rotating plates. Thus, the armrest on the seat plate can rotate against the mount board with 360 degrees and move forward and backward. | 07-28-2011 |
20110182534 | POSITIONABLE BALL BEARING - A ball bearing with multi-step is disclosed. The bearing has a round seat with rolling balls in annular arrangement. A flexible depressor is provided on the round seat. A cap covers the round seat and accommodates the flexible depressor. The center of the cap is provided with a shaft base for securing the depressor to press the round seat. The flexible depressor is provided with a plurality of holes corresponding to the rolling balls. A positioning effect arises when the rolling balls are just embedded in the holes. The rolling balls diverge from the holes to rotate when the cap is forced to rotate against the round seat. The depressor is deformed by the rolling balls. Next positioning effect will not arise until the rolling balls are embedded in the holes again. | 07-28-2011 |
