Abstract

Suspension and sliding guide for a door or the like, characterized in that the suspension and sliding guide of the door as a plain bearing is made essentially of a self-lubricating plastic.

Description

The invention relates to a sliding door or the like, with an elongated, stationary guide profile, and a sliding door of the aforementioned type with a belt drive.

Sliding doors of the known types are equipped with rollers or roller carriages to which a door leaf or the like is connected. Suspensions of this type are expensive and maintenance-intensive and occupy a large space.

It is an object of the invention to change a sliding door so that the mechanical expansion of the spatial variability is reduced and cost-reduced can be produced. In such a structure should be dispensed with the use of roles of any kind to.

The object of the invention is achieved by the features of claims 1 and 2. The dependent claims give a further structural design and various applications of the solution principle again.

It is proposed according to the invention that the suspension and sliding guide is designed as a plain bearing. The plain bearing consists essentially of a self-lubricating plastic. Such an approach eliminates the problem of "seizure". The plastic that is best suited for such applications because it already has a very low coefficient of friction in conjunction with other materials, is polytetrafluoroethylene. Basically, the sliding bearing consists of a compound with a polymer is added to the reinforcing materials in the form of fibers and fillers. Further, this compound includes embedded solid lubricants or the like within the polymer. The sliding guide is made of a profile, which consists for example of aluminum with a hard anodized surface. During the sliding movement, the lubricants are almost constantly transported to the surface of the sliding guide by a micro wear and thus automatically reduce the friction between the sliding guide and a sliding block. On the sliding block, which may be present in multiple versions, the door leaf of the sliding door is attached directly or indirectly.

The game between the slide and the shoes is adjustable in a preferred embodiment and can also automatically readjust to a predetermined value.

In the case where the sliding door is automated, for example, by a revolving toothed belt or the like, the door leaf attachment can also be integrated at the connection between the guide profile and the holder of the door leaf and connected to a strand of the endless belt. The endless belt is driven by a geared motor.

All-glass door leaves or wooden door leaves or framed glass leaves or the like can be used as door leaves. An adjustment device for height adjustment or the like can likewise be used between the guide and the wing attachment.
