ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a pull-out device including a stationary rail, at least one support roller provided in a front end region of the stationary rail, a pull-out rail supported on the stationary rail and displaceable over the at least one support roller upon being pulled out, and at least one running roller provided in a rear end region of the pull-out rail and displaceable, upon pulling out of the pull-out rail, along an overhanging flange of the stationary rail that defines a running surface. The present invention also relates to a camping car having at least one such pull-out device for displacing a pull-out section of at least one side wall of the car.
2. Description of the Prior Art
A pull-out device of a type described above is disclosed, e.g., in European Publication EP O 809 956A which disclosed a pull-out device for a tall cupboard. It is also known to provide pull-out devices of a type described above for displacing box-shaped side sections forming part of side walls of camping cars.
However, with conventional pull-out devices used for pulling out of the pull-out sections of side walls of the camping car, the stationary rail forms an obstacle in the pull-out position of the side section(s). When a space behind the pull-out section(s) need be used, the rear ends of the stationary rails in this space form barriers over which the car user can easily stumble.
Accordingly, an object of the present invention is to provide a pull-out device of a type described above devoid of the above-mentioned drawback.
SUMMARY OF THE INVENTION
This and other objects of the present invention, which will become apparent hereinafter, are achieved by providing a pull-out device having a pull-out rail the length of which is greater than the length of the stationary rail and which extends, in the drawn-in position of the pull-out device, beyond the rear end of the stationary rail, with the at least one running roller lying outside of the running surface, with the pull-out device being supported on a support element provided in the rear region of the stationary rail for supporting the pull-out rail in the drawn-in position.
In the pull-out position of the device, the stationary rail extends only slightly into the space, which was occupied by the pull-out section, with the bottom of the space being practically free of any obstacles. The device is very economical as less material is required for the relatively short stationary rail.
In a preferred embodiment of the invention, the support element has at least one roller over which the pull-out rail is displaced during a first phase of the pull-out when the running roller(s) is (are) outside of the running surface(s) of the stationary rail. When the friction is of no importance during this phase, instead of a roller(s), a slide bearing member can be provided.
The novel features of the present invention, which are considered as characteristic for the invention, are set forth in the appended claims. The invention itself, however, both as to its construction and its mode of operation, together with additional advantages and objects thereof, will be best understood from the following detailed description of preferred embodiments, when read with reference to the accompanying drawings.
