Description

The invention relates to an extendable rail system for drawers with the features of the preamble of claim 1.

The invention further relates to a drawer with such a rail system and a piece of furniture with such a drawer.

Rail systems with adjustable inclination devices for drawers are already known in a variety. So shows about the AT 409 067 B from May 27, 2002, a pull-out for drawers, each with a body-side mounting rail and one each drawer-side pull-out on the two sides of the drawer. The pull-out rails are provided at their rear ends with hooks which have horizontal retaining lugs which protrude in mounting position in openings in the drawer. The positions of the retaining lugs or the hooks with the retaining lugs is adjustable on the Ausziehschienen in the vertical direction. As a result, the drawer can be raised or lowered in its rear area, which leads to a tilt of the front panel of the drawer. Thus, the drawer or the front of the drawer can be aligned in the furniture.

A rail system with a height-adjustable holder of drawers is in the EP 0 701 787 A1 shown.

The object of the invention is to provide a rail system with an improved over the prior art adjustable tilt device.

This is achieved by the features of claim 1.

Thus, the use of another support point means that the drawer is also supported at this point and thus a more stable support structure is created, since thus the force is distributed to three points instead of two points. The fact that this additional support point is adjustable in height, it comes to this favorable force distribution in each adjustable angle Tilt device. Thus, the bending of the drawer at the third support point can be prevented.

Further advantageous embodiments of the invention are defined in the dependent claims.

It has proven particularly advantageous if the third support point is arranged between the first support point and the second support point. As a result, an optimal distribution of force on the three support points can be achieved, wherein it is particularly advantageous if the third support point is located substantially in the middle between the other two support points.

According to a preferred embodiment, it may be provided that the support points are located on at least two - preferably several - adjustable positions of the inclination device in a plane - preferably substantially on a line - are. This ensures that the underside of the drawer is also located on a plane, so bending can be prevented.

Furthermore, it can preferably be provided that the height of the third support point is adjustable in proportion to the height of the second support point by the tilt device. Thus, it is achieved that in any position of the tilting device can not come to a bending of the drawer at the support points.

It has proved to be particularly advantageous if the elements which form the third support point are rigid. By using inelastic, ie rigid, elements at the third support point, a deflection of the drawer is prevented at this point, since the third support point under load can not change its height. Thus, it is further ensured that the force distribution is evenly distributed to all support points.

Particularly preferably, it can be provided that at least one element, preferably an actuating element, which forms the third support point, is formed substantially wedge-shaped. Due to the wedge-shaped design of a Stellelementes can be a uniform and substantially continuous adjustment of the inclination angle by the tilting device.

It has proven to be particularly advantageous if the first adjusting elements of the tilting device, which at least partially form the second support point, and the second adjusting elements of the tilting device, which at least partially form the third support point, have a force-transmitting connection to each other. This ensures that the heights of the two adjustable support points can be changed simultaneously or uniformly.

As advantageous, it has further been found that the tilting device at spaced locations on the - preferably flat - top of a drawer rail of a rail system is supported. An adjustment of the inclination on a flat top of a drawer rail is easy to implement, since they are consistently designed to be accessible in commercial shop rails and a spacing can be easily realized.

Preferably, it can further be provided that the tilting device has a tilt protection for the drawer, which can be achieved that the drawer - especially when the rail system is extended - can not be detached from this.

Preferably, it can further be provided that the anti-tip device - preferably substantially completely - is formed on an actuating element of the tilting device. Thus, it can be achieved that the anti-tip device is functional in each set angle of the tilting device.

According to a possible embodiment, it can be provided that the inclination device has at least one actuating device for actuating the inclination device, wherein the height of the third support point and the height of the second support point are simultaneously, preferably without tools, adjustable with the actuating device. As a result, a convenient adjustment of the tilt device is created.

According to a preferred embodiment it can be provided that at least one element which forms the first contact point, is formed substantially wedge-shaped, whereby a substantially simple, non-impact by the support point insertion of the drawer is achievable in the rail system.

Protection is also sought for a drawer with a rail system of the type described.

Protection is also desired for a piece of furniture with at least one such drawer.
