Definitions

  • the invention relates to a telescopic extension for a refrigeration device according to the preamble of claim 1 and claim 8.
  • Rails of such a telescopic extension with which the refrigerated goods are moved out of the refrigerator, should be smooth, so that the carrier, even if it is heavily loaded, can be pulled out of the refrigerator with little effort.
  • pull-outs of this type have stops that limit the freedom of movement of the rails with respect to each other, so that the rails are not accidentally pulled apart completely.
  • the internal widths of refrigerators are subject to large tolerances due to the foamed housing and the different expansions of the materials due to the large temperature loads.
  • the carriers are mounted with a lateral play, so a game perpendicular to the direction of movement of the rails on the rails.
  • damage to the refrigerated goods carriers as a result of use can be substantially prevented by this loose acceptance of the refrigerated goods carriers on the extension.
  • Due to the game between carrier and extract it comes to the fact that the refrigerated goods wiggle sideways when moving back and forth. This leads to a reduction in touchable quality and thus to a depreciation of the refrigerator.
  • the invention has the object of providing a telescopic extension for a refrigerator in such a way that the refrigerated goods are smoothly moved to avoid damage to the refrigerated goods during normal use, the necessary large tolerances of refrigerators is taken into account and at the same time the impression of a high-quality system preserved.
  • the object is achieved according to the invention by a telescopic extension for a refrigeration device with the features of claim 1 and claim 8.
  • contact surfaces between the carriers and the rails are designed so that large frictional forces prevail between them.
  • Such friction surfaces prevent wobbling of the shells and thus also a possible tilting of the refrigerated goods, which is due to the conditional by the large tolerances game of refrigerated goods compared to the rails in the previous structure.
  • the lateral displacement of the refrigerated goods in normal use can be completely prevented, whereby the tangible quality is significantly improved.
  • Another advantage is that the friction surfaces have a damping effect, which leads to quieter movement noise when pulling out the refrigerated goods. As a result, a rattle of cheap refrigerated goods carriers made of plastic on the extracts can be prevented, which also causes a higher quality impression, although more favorable materials are used.
  • friction forces are to be understood according to the invention, which are greater than forces that arise when moving the carrier, so that also z. B. in jerky movements of the wearer, a relative movement at the contact surfaces between the carriers and the rails is at least largely avoided.
  • the coefficient of static friction of the frictional contact surfaces is between 0.3 and 1. This makes it possible to prevent a lateral wobbling of the refrigerated goods carriers without at the same time restricting too much the mobility of the trays in the direction of movement.
  • the value for the coefficient of friction is 0.7.
  • the rail to which the carrier is attached is provided with a surface which causes high adhesion.
  • the rail could be provided with a slip-resistant coating.
  • the surface of the rail could also be provided with a structure that causes greater friction. This solution is especially advantageous if the refrigerated goods carrier rests directly on the rail of the telescopic extension.
  • a carrier receptacle which serves to secure the carrier to the first rail with a tolerance, at least in the contact area with the carrier made of a material with high coefficients of friction, such as soft thermoplastic elastomer at least partially produced or with a support of such material Mistake.
  • the design of rail and carrier can be maintained, only in the selection of materials for the carrier support must be paid to a high coefficient of friction. So this represents a particularly advantageous solution that requires little structural changes to the previous structure and is easy to ensure. If only the bearing surface of the support receptacle made of a soft thermoplastic elastomer, so it is advantageous to produce the support receptacle itself, for example, polyoxymethylene or other high-quality plastic. As a result, the stability of the carrier mount and the high sliding resistance of the contact surface with the carrier can be ensured at the same time.
  • the friction surface is realized on the carrier itself.
  • the carrier is provided for this purpose with a material with a high coefficient of friction, such as, for example, a soft thermoplastic elastomer. This can prevent that changes to the relatively complex rail system of the telescopic extension must be made.
  • the material with a high friction effect is attached to the refrigerated goods itself, which may be a cheaper solution under certain circumstances.

Abstract

L'invention concerne une glissière télescopique pour un appareil réfrigérant comprenant au moins deux rails (14, 15) pouvant se déplacer dans le sens longitudinal l'un par rapport à l'autre, tout en étant guidés l'un sur l'autre. Un support (11) présentant une tolérance est monté sur le premier rail (14). Les surfaces de contact entre le support (11) et le premier rail (14) présentent un coefficient de friction élevé, ce qui empêche le glissement sur le rail, en direction et à partir dudit rail,.
