Description

Quick fastening device

The present invention relates to a quick-fastening device for fastening a guide rail on a horizontally extending rod having on opposite sides in each case a bent end portion which are fixed to posts of a lattice-like side part, wherein at least one bent end portion is encompassed by a clamp connected to the guide rail.

WO 2007/074114 discloses a quick-fastening element for fastening a guide rail of a pull-out guide to a lattice-like side part. For this purpose, the horizontal bar in an angled end region is gripped by a clip-like holding section, so that the two holding sections can be slid in a direction parallel to the angled end sections. This allows easy installation, however, the guide rail of the drawer guide is usually in the interior of a household appliance adjacent to the horizontal rod inside.

WO 2007/090738 discloses a quick attachment for a guide rail, in which two clip-like holding elements are provided, which can be pushed in a direction parallel to the longitudinal direction of the rod on the bent end portions, Thus, a mounting in a simple manner from a front side. Again, the clip-like holding portions embrace not only the bent end portion, but also the longitudinally extending portion of a rod, so that the structure is relatively large inwardly.

It is therefore an object of the present invention to provide a Schnellbefestigungseinrich- device for mounting a guide rail on a horizontally extending rod and / or a vertically extending post, which has a kompak ^¬ th structure and allows easy attachment of the guide rail. This object is achieved with a quick-fastening device having the features of claim 1.

According to the invention, a stop resting on a post on the side facing the guide rail is formed on at least one clip, so that the stop forms a safeguard against displacement of the quick-fastening device in the direction of the post. This ensures that the attachment points can be omitted at the region of the longitudinal extension of the rod and the attachment is arranged closer to the post, so on an outer wall of an interior, because the side rail with the rods is usually at one

Sidewall of an interior set, especially in an oven. As a result, the usable interior space is increased and the guide rail of the extension guide can be positioned further outside.

Preferably, a stop for abutment with a post on the side facing the guide rail is formed on both clamps, so that when the guide rail is loaded against the posts, support is provided on both clamps and pivotal movement of the quick-fastening device is prevented. The stop may optionally be plate-shaped and form a flat bearing surface, or be formed on a U-shaped holder. In the U-shaped holder has the advantage that not only forces can be transmitted in the direction of the posts, but also tensile forces of the guide rail are received by the post by the U-shaped holder. This requires that the U-shaped holder with a leg between the posts and a side wall, such as an oven, is inserted.

For a stable attachment of the quick-fastening device, a clip is preferably fixed on the bent end section of a rod via latching means. The locking means may be formed by bendable webs on the bracket, so that an easy assembly is guaranteed.

For easy fixing of the quick-fastening device, at least one clip has two U-shaped receptacles arranged at an angle to one another. This allows this clip by inserting a bent end portion or the post in a first receptacle and then pivoting such that the second U-shaped receptacle with a bent end portion or the post engages are easily mounted, the clip has a minimum material requirement, because by the formation of two U-shaped Recordings, the clip can be made very compact and material-saving.

For easy installation of the two clamps on the guide rail, both clamps can be fixed to a strip which is connected to the guide rail. As a result, the two brackets can be preassembled on the strip, so that only one fastening step is required, namely the determination of the strip on the guide rail. Alternatively, it is also possible to form the brackets integrally with the guide rail, so that can be dispensed with an additional bar. Another alternative is the direct fixing of the clamps to the guide rail. done by form or cohesive determination.

For a compact arrangement of the guide rail on the side rail, the guide rail is at least partially disposed above the rod, so that the quick-fastening device, the guide rail not next to a horizontal

Rod is positioned, but above, so that the usable interior of a baking oven or other household appliance is increased. Ideally, the same food support can be used, the management before mounting the drawer on the side rails were inserted into the side rail. Thus, in the fastening arrangement according to the invention, pull-out guides can be retrofitted to increase comfort. The user can continue to use the same Gargutträ ^¬ ger.

Preferably, the locking means embrace the rod or the post by more than half the diameter, so that a secure hold is ensured. The rod or the post is formed in cross-section usually circular, so that the locking means protrude by half or more to the rod or the post and ensure a secure fixing. The invention will be explained in more detail with reference to several embodiments with reference to the accompanying drawings. Show it:
