Description

The invention relates to a device for supporting and for movably guiding a chair in a provided in a housing, designed as a slot guide guide slot with a movable in the guide slot, a chair seat of the chair supporting trolley, wherein the carriage has a guide carriage and along a within the elongated hole guide arranged guide rail is movable, wherein the guide rail is formed as a centrally formed in the slot guide monorail, which is associated with the longitudinal side outer edges of the slot guide adjacent carriage body of the feed carriage.

Devices for supporting and for movably guiding a chair of the aforementioned type are used, for example, in meeting rooms of public buildings, in which the device is embedded, for example, in the hall floor to enable the chair position to be changed to a fixed table. In addition, it must be ensured that, when the chair is not occupied, the chair moves automatically over an inclined plane to a resting position, in which the seat is located as far as possible below the fixed table. Consequently ordered chair positions are automatically taken to provide sufficient passages behind the backrest surfaces of the chairs.

A chair guide of the aforementioned type is for example from the DE 203 20 975 U1 in which a slot guide is provided in the housing as a guide slot and serves as a chair holder a chair receiving sleeve, the lower end is tapered down and conical and is positively inserted in a correspondingly executed opening of the carriage.

In the built version of this chair guide, a two-rail guide is provided as a guide rail, which extends in each case in the two outer side edge regions of the slot guide and which is to be fastened via a plurality of screws as connecting elements. Due to different tightening torques of these screws, which can not be avoided in the assembly of such a chair guide, complex Nachjustierarbeiten are required here. In addition, it is difficult to provide a cover in this two-rail version.

Devices for supporting and for the movable guidance of a chair are from the DE 20 2011 001 821 U1 in which the chair receptacle is assigned an electrical, mechanical or pneumatically activatable and deactivatable firing device, via which the chair receptacle with the chair receptacle of the chair in the guide slot can be held in an adjustable driving position. In contrast, an object of the present invention is a device for supporting and to improve the mobile leadership of a chair of the type mentioned in such a way that it is functional with a reduced effort to assemble and move. In addition, the conditions should be created to be able to provide a cover for the slot guide functionally functional and easy to install here.

To solve this problem, the device of the type mentioned is characterized in that the housing has a cross-sectionally substantially C-shaped or substantially rectangular hollow profile and in his chair facing hollow profile section with at least one Verfahrnut for carrying out a part of the chair is provided, wherein the housing in total together with the guide rail and the carriage via height adjuster in an inclined position to the horizontal can be transferred.

Thus, a device for supporting and for the movable guidance of a chair is made available, in which, due to the guide rails designed as a monorail guide rail paths are formed on both sides of a lowered or raised area on which the two carriage body of Führurigsschlittens can slide along safely. The installation of this monorail guide is much easier and does not involve the risk that due to different tightening torques misalignment properties of the guide carriage are impaired.

The housing is a cross-sectionally substantially C-shaped or substantially rectangular cover hollow profile part and has in its the chair facing cover hollow profile part at least one Verfahrnut for carrying out a part of the chair receptacle, the housing altogether together with the guide rail and the carriage height adjuster in an inclined position is to be transferred to the horizontal.

Thus, a device for supporting and for the movable guidance of a chair is provided, in which initially the housing is not made of the solid, i. is made of a solid material to have created an internal cavity for receiving the guide rail, but in which the housing is first made on the housing side of a sheet metal profile produced by laser cutting. This can be done so that this is provided for example with a cover hollow profile part (head piece), e.g. in the manner of a cover plate, which has at least one Verfahrnut, but preferably two spaced-apart Verfahrnuten for receiving parts of the chair receptacle.

Such a hollow section part such as a cover plate can be held in the simplest case by magnets to a basic housing part, such as a bent base plate to remove it with little effort without tools can. For stiffening this bent basic housing part this can be closed at the open ends by screwed or welded end plates. This is the housing with cost-effective sheet metal components to create. To include gravity for automatic movement of the chair be able to use his chair seat along the guide slot, without having to carry out construction-consuming and assembly-side significant work requiring measures, it is envisaged that the housing overall together with the mounted guide rail, the carriage, the chair seat and the like parts on the height adjuster in an inclined position to the horizontal can be converted, that the entire device together with the assembled chair in weight relief, so when not occupying the chair, automatically moves into a non-use position due to gravity, in which the chair is located for example below a table surface with its seat to behind the backrest of a chair sufficient passage spaces to have created. If, for example, a cover plate held by magnets is provided as cover hollow profile, this cover plate is to be removed without tools, after which the height adjusters are accessible.

It is particularly preferred if the cover hollow profile, so for example, the cover plate, in turn höhenausrichtbar about distance adjuster relative to the housing, so that the set inclination of the housing, based on the floor level of a room, is to compensate for the height, so that the entire device through Height compensation or distance setting of the cover hollow profile part, so usually the cover plate, ground parallel to the floor level of the room can be embedded in the ground. For this purpose, for example, the chair receptacle have a connection area for a chair, which has an angle of> 90 ° to the horizontal, so that the chair based on the height level of the floor makes a right angle to the bottom surface of a room despite the inclination of the device.
