Definitions

  • the invention relates to a castor, in particular a free-running castor, with twin wheels, with a housing having a substantially vertically oriented, top-side spigot for receiving a pivot for connecting the roller with a piece of furniture or other object, and with a Housing transverse to the pin opening enforcing, the wheels bearing axle.
  • Puncture rollers are rollers with an axial passage opening in the region of the otherwise usual wheel axle and a wheel bearing, which is arranged radially in the region of the wheel jacket.
  • the "open" design is often perceived as visually appealing, but the design effort leads to increased production costs and the inner roller area is prone to contamination.
  • the object of the present invention is to develop a role of the type mentioned, which has the visual impression of a perforated roll, but is designed structurally simpler.
  • the invention is based above all on the recognition that the optical effect of a perforated roll can also be approximately achieved in that a mirror surface reflects the substrate on which the roll is located. According to the invention it is therefore proposed that the roller has a flat, mirror-reflecting axle cover. It is important that the axle Cover is flat, since a curved mirror surface does not produce the desired visual impression.
  • the flat, mirror-reflecting axle cover is designed as a wheel cap. This allows easy installation and, if necessary, replacement of the axle cover.
  • the flat, mirror-reflecting axle cover is preferably formed by a metal surface, for example a polished stainless steel or chrome surface. Cost-effective production can be achieved if the metal surface is a coating applied to a plastic carrier. It has been found that the desired optical effect occurs in particular when the mirror-reflecting axle cover is displaced or sunk axially in the direction of the wheel center relative to the wheel casing or the running surface.
  • the roller shown in the drawing consists essentially of a housing 10 with a pin hole for receiving a pivot or runner 12, by means of which the roller is rotatably mounted on a piece of furniture or the like, and two wheels 14, 14 'with tubular hubs 16, 16 ', which are attached to the free ends of a pivot pin 18 and rotate on this.
  • the wheels consist of a wheel body with sprayed running surfaces made of a material adapted to the purpose, For example, a soft material for use on hard floors o- a hard material for use on carpets o. The like.
  • the wheels 14, 14 ' also have hubcaps 20, 20', which are engaged in openings provided for the wheel body.
  • the hubcaps 20, 20 ' are made, for example, as injection-molded parts made of plastic. Their outwardly facing, flat viewing surfaces are provided with a mirror-reflective coating, such as a chrome coating.
  • the visible surfaces of the hubcaps are further arranged opposite the outer bead of the wheel body axially sunk toward the center of the wheel. In the use of the role created by the mirror surface, which reflects the background, the visual impression of a hole role, without the considerable design effort of such a role is required. Furthermore, the hubcaps protect the interior of the roller from contamination.

Abstract

L'invention concerne une roulette de guidage comprenant deux roues jumelles (14, 14'), un boîtier (10) pourvu d'une ouverture sommitale dirigée pratiquement à la verticale pour recevoir un pivot (12) destiné à relier la roulette à un meuble ou à un autre objet, et un boulon axial (18) qui traverse le boîtier transversalement à l'ouverture et supporte les roues. L'invention vise à obtenir l'impression optique d'une roulette à trou. A cet effet, selon l'invention, la roulette présente un chapeau d'axe (20, 20') plan, réfléchissant comme un miroir.
