20100212108 | Castor Having Reinforced Strength - A castor includes an upright support tube, a mounting unit rotatably mounted on a lower end of the support tube, and a support bracket secured on the mounting unit. The mounting unit includes an upright hollow mounting post mounted on the support bracket and inserted into the support tube and a plurality of reinforcing plates mounted in the mounting post to reinforce a radial strength of the mounting post. The mounting post of the mounting unit has an outer wall provided with a plurality of radially and outwardly extending bushings abutting the inner wall of the support tube to reduce a friction between the mounting post and the support tube so as to facilitate rotation of the mounting post relative to the support tube. | 08-26-2010 |
20110037297 | Baby High Chair - A high chair includes a front support frame ( | 02-17-2011 |
20120255141 | Castor Assembly - A castor assembly includes a support unit, a frame unit, a brake unit, and an operation unit. The frame unit includes a frame, a locating flange, and a wheel. The support unit includes a bearing, and an inner bushing. The brake unit includes a control shaft, a braking block, a lower toothed disk, an upper toothed disk, a locking block, and an elastic member. The operation unit includes a housing, a drive seat, a pressing roll, a cam block, and a restoring member. Thus, when the braking block presses the wheel to stop movement of the wheel, the upper toothed disk meshes with the lower toothed disk to lock the lower toothed disk and the braking block so that the wheel is locked and cannot be turned freely when the wheel is braked. | 10-11-2012 |
20130174375 | COMBINATION CASTOR WHOSE CASTOR ASSEMBLIES ARE BRAKED AND POSITIONED SIMULTANEOUSLY - A combination castor includes a linking device, and a plurality of castor assemblies connected with the linking device. Each of the castor assemblies includes an operation unit, a braking unit, and at least one roller. The operation unit of each of the castor assemblies includes a mounting seat, a slide, and a driven block. The braking unit of each of the castor assemblies includes a bushing, a housing, a control shaft, and a braking member. The roller of each of the castor assemblies has an inner periphery provided with a plurality of locking grooves. Thus, the linking device can drive and operate the castor assemblies to brake and position the castor assemblies simultaneously. | 07-11-2013 |
20130174377 | COMBINATION CASTOR WHOSE CASTOR UNITS ARE BRAKED SIMULTANEOUSLY - A combination castor includes a control unit, a linking unit, and at least two castor units. The control unit includes at least one mounting seat, at least one bushing mounted in the at least one mounting seat, and a pedal pivotally located at a side of the at least one mounting seat. The linking unit includes a propeller shaft extended through the at least one bushing and locked onto the pedal, at least one rotation plate secured on the propeller shaft, and at least two links each pivotally connected with the at least one rotation plate and the respective castor unit. Thus, when the pedal is stepped, the propeller shaft is driven to rotate the at least one rotation plate which drives the links to operate the castor units so as to brake or position the castor units simultaneously. | 07-11-2013 |

20100313367 | Cleaning apparatus with quickly replaceable cleaning head - A cleaning apparatus comprises: a main rod, a fastening device, a cleaning head and a wringing device. Two holding plates are mounted on the fastening device via two movable connecting pieces. The cleaning head has two hold plates and a sweeping element, attached to lower sides of the held plates. The held plates carry L-shaped fastening devices which respectively engage with openings in the holding plates and point outward, thereby being stably held in place due to elasticity of the sweeping element. Mounting and removing of the cleaning head is performed in a single step by longitudinal compressing of the sweeping element and allowing the fastening elements to engage with and disengage from the openings. | 12-16-2010 |
20100313368 | Cleaning head with fixing device for cleaning apparatus - A cleaning head with fixing device is used in conjunction with a cleaning apparatus and mounted at a lower side thereof, comprising a cleaning element and first and second adhesive plates, which are attached to a top side of the cleaning element and a lower side of the cleaning apparatus; The first and second adhesive plates have a plurality of hooks and a fiber surface, which engage with each other for mounting the cleaning element on the cleaning apparatus. | 12-16-2010 |
20100313369 | Cleaning apparatus with easily replaceable cleaning head - A cleaning apparatus has two cleaning heads which are alternatively used for different cleaning, applications; in particular, a first cleaning head with a comparatively large surface for cleaning large areas and a second cleaning head with a sponge; The first and second cleaning heads are mounted on lower sides of two holding plates and easily replaced. | 12-16-2010 |
20100313370 | Cleaning apparatus with tiltable cleaning head - A cleaning apparatus with tiltable cleaning head comprises a main rod, two wringing plates, a cleaning element with a bottom surface, a fastening device, a wringing device, and two connecting assemblies, Each of the two connecting assemblies has a first connecting piece, which is hingedly connected with the fastening device, and a second connecting piece, which is hingedly connected with one of the two wringing plates, The first and second connecting pieces are connected at a variable angle, allowing to incline the main rod, while the bottom surface of the cleaning element rests entirely on a floor to be cleaned, so that cleaning is made with better effect and less effort. | 12-16-2010 |
