Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drawer guide assembly for a drawer, shelf, etc., which guide assembly comprises a support rail disposed on each side of the body and a drawer guide assembly on each side. a load-transferring runner roller mounted on a runner support member disposed between the rails, the support rail extending on at least one side of the drawer over at least a portion of its length; It has a U-shaped part and a vertical guide part for the drawer projecting from the lower horizontal flange.

Drawer guide assemblies of the type described above allow the drawers or shelves to run smoothly and also carry relatively heavy loads, and the manufacturing costs of the runner supports and the rollers supported thereon are made of injection molded plastic material. and its running properties are comparable to or superior to those using drawer guide assemblies with ball bearings mounted on their rails.

This type of drawer guide assembly not only provides smooth running of the drawer, but also supports the individual parts of the drawer and drawer guide centering assembly with lateral stability. Tilting movements of the drawer are thus avoided and no wobbling of the drawer occurs during drawing and insertion.

The object of the invention is to provide a drawer guide assembly of the above type, which has satisfactory lateral stability and thus in particular ensures smooth running of the drawer.

According to the invention, the object is such that the runner rollers of the runner support member move on the support rail and that the lower vertical guide portion has a corresponding guide flange, such as a downwardly projecting drawer rail or a slide of a drawer rail. This is achieved by an arrangement which forms a lateral guide for the drawer by lateral abutment with the guide element.

The design according to the invention provides a direct lateral guidance effect between the support rail and the drawer rail, or between the support rail and the drawer itself, which are dependent on the runner rollers or runner support elements arranged between these parts. It cannot be obtained by The lateral stability of the drawer guide assembly is thus considerably improved.

Preferably, a guide member is provided which is molded into the retaining member for the drawer rail which can be inserted into the side wall of the drawer and which projects into the shaped portion of the support rail.

It is further preferred that transverse guiding elements such as slides or rollers are provided to guide the guiding flange at two longitudinally offset points of the rail.

In another embodiment of the invention, the guide flange is formed by a U-shaped section curved from the rail.

In a further embodiment of the invention, the guide flange is formed with a U-shaped groove section and a guide element, for example a slide, is fastened to another rail extending into the groove.

The invention will be explained below with reference to the drawings.

The rail with lateral guides according to the invention is characterized in that it is provided only on one side of the drawer, while the rail on the other side of the drawer is not provided with lateral guides. Therefore, tolerances in the body of the furniture and in the installation of the drawer guide assemblies are allowed as the rails can have a slight gap between them on the sides of the drawers that do not have guides. . Nevertheless, precise lateral guidance of the drawer is guaranteed. In the following description, only one side of the drawer or shelf will be discussed.

The drawer guide member assembly according to the present invention has a support rail 1 disposed on the side of the main body of the furniture, a drawer rail 2 disposed on the side wall of the drawer, and a load transmission runner roller 9. It includes a runner support member 3 arranged between the rails. The guide element 15 is preferably made of plastic material and is attached to the front end of the drawer rail 2,
Ensures correct vertical alignment when the drawer is in the closet position.

In the embodiment according to FIGS. 1 to 6, the support rail 1 has, at least in part, a J-shaped cross-section. In the embodiment shown in Figures 3 and 4, the J-section extends over the entire length of the drawer. At the upper horizontal flange 1' of the J-shaped cross section,
The runner support member 3 runs by its runner rollers 9.

The support member 1 has a free vertical flange 1' at its lower end, which ensures a lateral guiding movement of the drawer.

In the embodiment of FIGS. 3 and 4, the side walls of the drawer have continuous guide flanges 5. In the embodiment of FIGS. Said guide flange 5 projects into the profile of the support rail 1.

A transverse compensating roller 12 with a vertical pivot axis
It is attached to the runner support member 3. Said compensating roller 12 is connected to the drawer or drawer side wall 8 on one side;
and on the other side the central flange 1 of the support rail 1
run.

In the embodiment shown in FIG. 4, another guide flange 5' is provided on the drawer side wall 8, so that the free vertical flange 1'' of the support member 1 is surrounded on both sides by guide members 5, 5'. In this embodiment, the compensating roller 12 can also be omitted.
However, it has been proven that due to the cooperative action of the only guide flange 5 with the compensating roller 12, a very smooth guidance of the drawer is obtained with satisfactory sliding properties.

In the embodiment shown in FIG. 6, an insertable retaining member 13 is arranged in the side wall 8 of the drawer. The holding member 13 receives the drawer rail 2 on one side;
On the other hand, a guide flange 5 is attached to the holding member, which is preferably made of injection molded plastic material. In the embodiment shown in FIG. 5, a retaining member 13' similar to that described above is used.

In the embodiment shown in FIG. 5, the drawer rail 2 is provided with a guide flange 4 that projects downward.

In these embodiments, the guide element is the slot 11
The guide flange 4 of the pull-out rail 2 projects into the slot 11.

In the area of the support member 10, the support rail 1 also has a J-shaped cross-section, but in this case the support rail 1 is a composite member.

As can be seen in FIG. 3, the drawer rail 3 does not have to be a separate structural member. For example, a groove may be formed in the side wall 8 of the drawer. All that is required is for it to function as a pull-out rail.

Also in the embodiments shown in FIGS. 7 to 17,
The drawer rail 2 has a guide flange 4 that projects downward. The support rail 1 has support elements 10 for transverse guiding elements.

In the embodiment shown in FIGS. 7 to 9, the lateral guide elements are rollers 16 arranged on both sides of the guide flange 4. In the embodiment shown in FIGS.

In the embodiment shown in FIGS. 10 and 11,
The guide element is formed by a slide 7 with a slot 11 into which the guide flange 4 of the pull-out rail 2 projects.

In the embodiment shown in FIG. 10, the guide flange 4 of the drawer rail is bent to form a U-shape to increase its lateral stability and to be able to carry large lateral loads.

In the embodiments shown in FIGS. 12 to 14,
The drawer rail 2 is connected to the shelf 1 by the curved member 17.
It is fixed at 8. The guide flange 4 has an angle with respect to the lower horizontal flange 2' of the U-shaped drawer rail 2.

The support rail 1 has an L-shape and is provided with a support member 10 for the slide 7 on its vertical mounting flange.

In the embodiments shown in FIGS. 15 to 18,
The guide flange 4 is attached to a support rail 1 arranged on the side of the furniture body. Said support rails 1 on the sides of the furniture body are U-shaped and receive runner support members 3. In the embodiment shown in FIG. 18, the guide flange 4 of the support rail 1 is inclined relative to the horizontal flange 1'.

In the embodiment shown in FIG.
The guide flange 4 is a double flange 4', which flange 4' is a transverse flange with a U-shaped groove.
In the embodiment shown, this groove is a separate rail welded to the support rail 1 on the side of the furniture body.

The other side of the drawer guide member will not be described above. These two sides can be equal, or the other side can be configured at the current support level.
