| 20140331450 | Mechanically interlocked wheel - A caster wheel for a transportation vehicles comprises an axle assembly, a core, a polyurethane tread, and an elastomeric infill, interposed between an aluminum core and a polyurethane tread. The wheel is manufactured by a multi-stage injection molding or liquid cast process, in which the tread and core are formed separately by injection or liquid cast molding, located in a mold, whilst the elastomeric infill is molded between them. A mechanical interlock is achieved directly between the tread and the elastomeric infill of the aluminum core, whilst the core and the infill are directly mechanically and chemically bonded. The invention wheel cores have oblong slots to let the liquid cast polyurethane flow through and create a strong mechanical and chemical bond. Thus a method of manufacturing forming a relatively rigid core part, forming a ground engaging tread, and molding an elastomeric infill between the core and the tread. Conveniently the core and the elastomeric infill are directly chemically bonded, whilst preferably the ground engaging tread and the infill are directly mechanically interlocked. | 11-13-2014 |

| 20120066862 | FLOOR PROTECTORS FOR CASTERS - To protect floors against marks or damage from casters , a shrinkable tire, for example, a piece of heat-shrink tubing, in its unshrunk condition, is fitted around the caster circumference and then is shrunken. The dimensions and shrinkage ratio of the shrinkable tire are selected such that, when shrunken onto the caster, the tire grips the caster securely. If desired, the frictional grip between the tire and the caster circumferential surface may be enhanced by applying to the interior of the unshrunk tire a hot-melt adhesive which will be activated by the heat applied to shrink the tire. Additionally or alternatively, the width of the tire may be greater than the width of the caster so that, when the tire has been shrunken onto the caster, marginal portions of the tire form flanges gripping the caster on opposite sides. | 03-22-2012 |
| 20120079681 | Protective Device for Castor - A protective device for a castor includes a mounting ring, and a driving piece secured on the mounting ring. The mounting ring has an outer periphery formed with a breakable portion which is located beside the driving piece. The driving piece has a first end extending from the mounting ring and a second end formed with a pull tab. When the mounting ring is released by tearing the breakable portion, the mounting ring is directly driven by the driving piece to remove from each of the two rollers of the castor. Thus, the user only needs to apply a single action to pull the pull tab of the driving piece so as to remove the protective device from the castor completely so that the protective device can be removed from the castor easily and quickly. | 04-05-2012 |
| 20130097808 | CASTER WHEEL BUMPER - A protective bumper attaches to a caster wheel assembly and substantially surrounds the assembly to act as a point of contact with other objects or articles, in order to limit or prevent damage to struck objects, and/or to the caster wheel assembly, and/or to a movable object or article supported on the caster wheel assembly. The protective bumper includes an outer bumper portion and an inner frame portion that attaches to a frame of the caster wheel assembly. The bumper may be attached to the caster wheel assembly via an axle that rotatably couples a wheel to the frame of the wheel assembly. Optionally, the outer bumper portion may be fitted with a relatively soft annular outer member or surface. | 04-25-2013 |
