| 016031000 | Frame | 7 |
| 20100011537 | Structure of a foot member of a baby mesh bed - A foot member of a baby mesh bed includes a base part, and a tubular part; the tubular part is securely joined on a lower end of an upright rod of the mesh bed, and has two embedded protrusions on an outer side, and a detainment hole; the base part has an uppermost joining portion, which has two embedding cavities, and a wedge piece thereon; the base part and the tubular part are joined together with the embedded protrusions being embedded in the embedding cavities respectively, and with the wedge piece of the base part being detained in the detainment hole of the tubular part; the base part can be separated from the tubular part for the mesh bed to occupy less space, thus being able to be packaged in a smaller case. | 01-21-2010 |
| 20110061198 | ROLLING DEVICE - A rolling device includes a frame, a rotatable member, a roller and an operating member. The frame is configured for being attached to a device enclosure. The rotatable member is secured to the frame and rotatable about a first axis relative to the frame. The roller is secured to the rotatable member and rotatable about a second axis parallel to the first axis. The operating member is secured to the rotatable member and rotatable about the second axis and capable of rotating the frame about the first axis. | 03-17-2011 |
| 20110083298 | Wheel seat reinforcement structure - This invention relates to a wheel seat reinforcement structure, in which a rotary shaft is provided on the wheel seat and a teeth portion is provided on the bottom end of the rotary shaft. A cover body extended on the wheel seat and having a left and a right rib strips for partial shielding is provided at both sides of the cover body. A shaft seat for mounting the wheel body is provided at the center of left and a right rib strips. An auxiliary connection seat is extended from the lower side of the shaft seat to the cover body. In this manner, when the shaft seat of the wheel seat is subject to the action of external force, the force can be uniformly distributed on both sides. Further, together with the support on the bottom portion, better reinforcement support effect can be achieved. | 04-14-2011 |
| 20130205544 | SHOCK-ABSORBING CASTOR - A castor includes a casing constituted by a part having at least one housing suitable for receiving a pivot defined on an axis, and a bearing defined on an axis perpendicular to the axis, at least one wheel suitable for running on a surface, a shaft mounted to co-operate in the bearing, the wheel being mounted in association with the shaft, the part being constituted by at least two portions and that are made respectively of two materials of different flexibilities, the portion presenting the greater flexibility being interposed between the housing and the axial orifice of the bearing so as to isolate the housing and the bearing from each other. The castors may be used with furniture or the like, in particular in a hospital setting, e.g. for beds, tables, walkers, and also for moving suitcases, baggage, or the like. | 08-15-2013 |
| 20130255034 | MULTI-PURPOSE CASTER AND METHOD OF USING SAME - A multi-purpose caster and method of using same includes a yoke arrangement having a body supporting a first portion of a spindle. The spindle further comprises a second portion projecting away from the body for insertion into an object during use. The yoke arrangement also includes spaced first and second arms forming a well therebetween. The arms secure an axle that passes through the well during assembly. A selection assembly is rotatably connected to the axle. The selection assembly includes at least two transfer mechanisms of differing modes of movement capable of selectable rotation within the well. | 10-03-2013 |
| 20150007414 | CASTOR ASSEMBLY - A castor assembly comprising a base plate, a wheel assembly extending from base plate, a vertical support member plate, a vertical retaining member, a retaining bolt, and a horizontal retaining member. The vertical support member has a pair of vertically spaced slots. The horizontal retaining member extends from the retaining bolt and is movable along the retaining bolt in a way that the horizontal retaining member is positionable between an open position, a first closed position wherein the horizontal retaining member is disposed in the first slot to retain an object having a first size in the object receiving space, and a second closed position wherein the horizontal retaining is disposed in the second slot to retain another object having a second size that is different from the first size in the object receiving space. | 01-08-2015 |
| 20110225769 | Castor Assembly for a Chair - A castor assembly includes an upright support shaft, a leg mounted on the support shaft and a pressing sleeve mounted between the upper end of the support shaft and the leg. The upper end of the support shaft has a retaining groove. The pressing sleeve has an inner wall provided with an inner flange retained in the retaining groove of the support shaft and an outer wall provided with an outer flange. The leg has an end portion provided with a receiving space pressing the outer flange of the pressing sleeve. Thus, the support shaft is combined with the leg by the pressing sleeve to prevent from defining a gap between the support shaft and the leg so that the support shaft will not hit the leg so as to prevent from producing noise or vibration. | 09-22-2011 |
