20080313854 | Transport Roller for a Transfer Car - The invention relates to a transport roller | 12-25-2008 |
20100287730 | RUNNER PIN FOR A ROLLER - The invention relates to a caster, in particular furniture caster, having a housing which is rotatably fastened, by means of a caster stem arranged vertically in an opening of the housing, to an object to be supported by the caster, wherein the caster stem has a first section which is arranged in the opening of the housing and a second section which projects beyond the housing. To create, in a simple and cost-effective manner, a caster stem which permanently prevents an undesired generation of noise as a result of relative movements between the caster stem and the object to be supported, it is proposed according to the invention that at least two annular grooves are provided in that section of the caster stem which projects beyond the housing, in which annular grooves in each case one elastic retaining ring is arranged without play. | 11-18-2010 |
20110131758 | DETACHABLE WHEEL SET FOR MOVING CASE - A wheel set which is detachably mounted on a case is disclosed. The wheel set includes a wheal set, a binding strip and a fastening unit. The wheal set includes a mount plate and a wheel mounted thereon. The binding strip is a single Velcro strip having both a hook surface and a loop surface so as to bind up a case and fasten each other. The fastening unit is fixed on the mount plate and is a Velcro fastener corresponding to the binding strip, so that the wheal set can be detachably fastened on the case by fastening the fastening unit on the binding strip. Thus the case can be easily moved by the wheel set. | 06-09-2011 |
20130117965 | FLOOR PROTECTOR - A floor protector comprises: a base that includes a base cavity on the underside of the base, a buffer that is partially recessed within the base and is permanently affixed inside the base cavity, and a screw that penetrates the buffer and base to attach the floor protector to a piece of furniture. The buffer is comprised of a soft and durable material such as felt. The base and buffer may be round in shape, and the base has a larger diameter than the buffer. The floor protector may further include a base aperture and a buffer aperture through which the screw passes when attaching the floor protector to a piece of furniture. In one embodiment, the base further includes a second cavity above the base cavity wherein the second cavity houses the head of the screw when the floor protector is attached to a piece of furniture. | 05-16-2013 |
20140137371 | LEG CAP AND CASTER MOUNTING HARDWARE - A leg cap and caster mounting apparatus having a base with a leg-engaging top side and a bottom side, a center hole extending through said base from said bottom side to said top side, and a perimeter wall defining an open top and extending vertically and upwardly from said base and having an exterior side and a leg-engaging interior side, said open top sized to accept the end of a table or furniture leg. The top side includes a nut well shaped to accommodate a nut and to prevent said nut from turning when a threaded shank of a caster wheel assembly is threadably inserted into said nut. A method of capping a table or furniture leg and installing a caster wheel assembly is also disclosed. | 05-22-2014 |
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 |
20090025177 | Constructive arrangement applied to swivel castor guards - A constructive arrangement applied to swivel castor guards represented as an improvement that provides the possibility to interchange an infinite variety of end pieces on a single basic castor structure, providing the ability to create a wide range of castor models at a reduced cost, considering that the constructive arrangement disclosed requires a reduced amount of investment in production tooling, limited to the interchangeable end piece, as the new components, namely the main body with a wheel guard having a slot on its trailing end face and the intermediate part, which are part of the improvement, can be considered as standard parts. | 01-29-2009 |
20110146027 | Castor Assembly Having Adjustable Height - A castor assembly includes a castor body, a threaded rod rotatably mounted on the castor body, a lower adjusting cover surrounding the threaded rod to cover the threaded rod and secured on the threaded rod to rotate the threaded rod relative to the castor body, an upper adjusting cover surrounding the threaded rod to cover the threaded rod and retractably mounted on the lower adjusting cover, and an elastic member mounted on the threaded rod and biased between the threaded rod and the upper adjusting cover to push the upper adjusting cover outwardly relative to the lower adjusting cover. Thus, the threaded rod is covered by the lower adjusting cover and the upper adjusting cover to enhance the aesthetic quality of the castor assembly. | 06-23-2011 |
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 |
