This is slide over the axle stub (6) which fits into the blind hole in the axle. The end of the axle is slotted to form claw fingers, with retaining tags (19) pointing towards the axle stub. The tags engage a groove in the axle to fit the wheel. An L-profile retaining ring (23) slide over the hollow axle and when the wheel is clipped onto the stub the ring is slid over the claws to secure the fitting. It is prevented from sliding off the claws by moulded lips (27).

Castor with roller body and hub for furniture

The hub serves for rotary mounting on a bearing, on which the castor (30) is axially held by a holding element (50) at one castor side and connectable to it. The holding element contains a holding lug (53), which positively coacts with a bearing (60) holder (62) in the connected state.Pref. the holding element is connectable to the castor in axial direction. In the connected state the holding lug coats with the holder orthogonally to the castor axis. The holding element may be an elastically deformable disc with a central aperture for the holding lug, from which radiates a slot to the dive edge.

Castor with inner ball bearing - has castor tyre firmly connected to ball bearing outer race

The castor wheel consists of an inner ball bearing to whose outer race is firmly connected the castor flexible outer part and has a simple set of ball bearing shells, without any special moulded tracks.

To manufacture the roller, the tire, which is molded in a separate operation, is placed in a mold cavity that is configured to seal against the side walls of the tire and yet permit the tire to expand radially, maintaining the seals along the tire side walls throughout the expansion. Once the mold is closed, a polymer in a plastic state is injected into the region of the cavity surrounded by the tire, there being enough polymer forced into the mold to expand the tire radially against an outer surface of the cavity. The expansion of the tire exceeds the shrinkage that the polymer experiences upon cooling and assuming a rigid state, and ...

Skateboard truck and caster with suspension mechanism

The present invention relates generally to skateboard and caster devices. More particularly, in a manner the invention concerns both dual wheel and single wheel axle supports of trucks and casters having a suspension mechanism for absorbing shock. The suspension mechanism is uniquely designed to progressively increase suspension resistance as forces acting on the mechanism increase by elastically deforming an independent arm in a manner to contact another arm or structure thereby transforming the independent arm into a dependent arm that results in a progressive resistance to a load until the forces are terminally engaged into a resilient abutment. A novel alignment mechanism functions to maintain the skateboard steering function.

In molding the stator member in the roller member, circumferentially spaced portions of the inner bearing surface of the roller member are preferably sealed from the mold cavity for the stator member so that the stator member is formed with a noncircular cross-section with only circumferentially spaced portions having a shape conforming to and in a running fit with the inner bearing surface on the roller member.

Method of making a support roller

A roller for supporting the rotating drum of a clothes drier or similar appliance includes a hub which is molded from a suitable polymer and a rubber tire which fits around and is interlocked with the hub. The tire is of uniform cross-sectional configuration and is stressed so that it remains in intimate contact with the hub rim, even after substantial use. To manufacture the roller, the tire, which is molded in a separate operation, is placed in a mold cavity that is configured to seal against the side walls of the tire and yet permit the tire to expand radially, maintaining the seals along the tire side walls throughout the expansion. Once the mold is closed, a polymer in a plastic state is injected into the region of the cavity surrounded by the tire, there being enough polymer forced into the mold to expand the tire radially against an outer surface of the cavity. The expansion of the tire exceeds the shrinkage that the polymer experiences upon cooling and assuming a rigid state, and as a consequence the tire remains stressed and in intimate contact with the hub.

Urethane wheel with crack prevention

The present invention comprises: an urethane wheel having an urethane layer; and a load dispersion unit configured to have a shape of a predetermined groove along a circumferential surface of the urethane wheel, formed at a predetermined ratio with respect to thickness of the urethane layer, and having width and depth thereof to have the same length. The load dispersion unit is formed on a surface of the circumferential surface of the urethane wheel through one line processing or three line processing to disperse frictional stress due to load of a contact surface during driving and static load distributed on the contact surface on the surface of the urethane wheel to delay and minimize a crack on the surface of the urethane wheel. Therefore, the present invention extends a replacement period of the urethane wheel, thereby reducing cost and time required for replacement work and minimizing a production loss generated by frequent replacement.

Electroconducting plastic rollers - produced by mixing metal strips or wires with polymer in extruder, pref. plus glass fibres and polyamide, and moulding to shape

Electroconducting plastic rollers are produced by mixing 30 - 70% wires, strips of metal foil or other metallic strips with 30 - 70% polymer, plasticating and homogenising the mix in an extruder, and moulding the mix into rollers. One pref. version uses polyamide plug glass fibres. Pref. copper is used as the metal and the addn. of glass fibres to the mix assists homogenising. The addition of polyamide beforehand prevents oxidn. of the metal. In use a spring-loaded conductor touching the roller ensures continuous earthing, e.g. when doors run on the rollers concerned. In Fig. 3 there is a centre hole (7) for mounting on a bearing. Annular recesses (8) on the sides save weight. A circumferential groove (9) enables the roller to run on a track. ADVANTAGE - The prods. do not become electrically charged and hence cannot give a shock to anyone touching them. They also have the usual advantages of plastic materials (e.g. corrosion resistance, self-lubrication etc.).

Scrub-mate

A novel solution for converting a walk behind floor scrubber into a sit and ride behind floor scrubber. The present invention consists of a chassis frame to which five wheels are attached. Two of the front wheels pivot and the up-front safety wheel does not. The wheels that are attached to the rear of the frame, are non-pivotal. A person sits on the cushioned seat. Upon grabbing the floor scrubber's control handles and rotating them forward the floor scrubber, as it propells forward, pulls the present invention behind it in tandem. This allows the operator for the floor scrubber to sit and rid instead of walking, while cleaning large commercial size floors. This new procedure saves enormous time and the person controlling the scrubber will be less fatigued from hours of walking. The Scrub-mate is new to the floor cleaning industry, because it eliminates walking of the operator while using a battery-powered walk behind floor scrubber.
