It is proposed that the accessory carrier along the contact surface has at least one support element for reducing the contact surface. In this case, a support element is to be understood in particular as an elevation emerging from the surface of the contact surface, which extends from the accessory support in the direction of accessories and thus spaces the original surface of the accessory support from the accessory. Such a support element on the accessory carrier defines the contact surface new and unique and ensures that each input and

Ausschubbewegung an optimized, preferably reduced contact surface of the

Accessory carrier comes into contact with the accessories and thereby causes better properties with respect to the friction.

Preferably, the support element has a height H, wherein the height H is between 0.05 mm and 8 mm, preferably between 0.5 mm and 2.5 mm and in particular 0.8 mm. In particular, the height H is to be understood as the vertical extent of the support element measured in the z-direction in the installation position. This effective height, measured from the surface of the accessory carrier to the common contact surface on the accessory, spaced the contact surface to the surface of the

Accessories carrier. Preferably, the support element has a width BA and the accessory carrier has a width BZ, wherein the width of the support element BA is smaller than the width of the

Accessory carrier BZ, preferably the width of the support element BA is less than 1/4, in particular less than 1/8 of the width of the accessory carrier BZ. The width BA is to be understood in particular as meaning the horizontal extent of the support element measured in the installation position in the x direction. This effective width, measured from the left to the right side of the support element defines the width of the

Contact surface and thus also the friction between support element and accessories. The width BZ is to be understood in particular as meaning the horizontal extent of the accessory carrier measured in the installation position, measured from the left to the right side of the accessory carrier, as measured in the x direction.

Under a buckeiförmigen element in particular a separately trained survey to be sanded, which is advantageously curved. Such point or buckeiförmigen elements, formed from a single or multiple support elements, achieve a plurality of individual

Contact surfaces, which minimize the friction targeted. In addition, these humps can arise through gaps in or between support elements.

Preferably, the contact surface of the support element has a flattened

Contact surface on. A flattened contact surface should in particular be understood to mean a spherically formed surface whose mushroom-shaped cross section minimizes the contact surface and thus ensures good sliding properties.

Preferably, the contact surface of the support element has a rounded

Contact surface on. A rounded contact surface should be understood to mean, in particular, an area whose edges are degenerate or rounded off. Thus, both on the accessory and on the accessory carrier damage such. Scratches or dents, avoided because the accessory does not butt against edges on the support element, but is lifted by means of rounded edges homogeneous on the contact surface / directed. Preferably, at least two are in on the surface of the accessory carrier

Longitudinal direction of the accessory carrier ersteckende support elements arranged side by side. These mutually parallel support elements allow a particularly good and tilt-free, rail-like guidance, the individual

Support elements can be continuous or interrupted, preferably in the form of humps.

According to a variant, at least two support elements in the longitudinal direction of the accessory carrier are arranged offset to one another on the surface of the accessory carrier. Such, viewed in the direction of insertion, left alternatingly arranged left Support elements achieve good sliding properties and require little material, since one can dispense alternately on a support element.

Preferably, the at least one support element made of a material with a low coefficient of friction, for example, bronze, cast or

temperature-resistant plastic, formed. Under a material with low

Friction coefficients are in particular materials to see, a dry friction coefficient dry preferably <0.5, in particular <0.25, to allow good sliding properties of the accessories on the accessory carrier.

Preferably, the surface of the accessory carrier, in particular the

Support elements on a friction-reducing coating. A friction-reducing coating, preferably PTFE, is used due to its low surface tension and good heat resistance and additional non-stick coating to slide the accessories on the accessory carrier friction and noise-free and to ensure easy cleaning, in particular between the support elements.

Preferably, the accessory carrier is a side rail, a pull-out system or a rib. Under a side rail should in particular one from vertical and horizontal
