Pull-out guide for pull-out furniture parts

The innovation concerns a pull-out slide for pull-out Furniture parts, such as drawers and the like., With two profile rails, one of which is one in its basic shape Has a C-shaped cross-section and is attached to the fixed furniture part and the aridere on the pull-out furniture part can be fastened and with a flange .under the upper surface engages in the profile opening of the fixed profile rail, the bottom of this flange and the top of the lower flange of the fixed profile rail running surfaces for those mounted on the other profile rail Form rollers and if the furniture part tilts when pulling out only the top or bottom of the outer circumference The front side of the roller is provided with a possibility of engagement with the profile rail that can be moved relative to it.

This type of pull-out runners are used in furniture construction for kitchen furniture, refrigerated cabinets, shop fittings and office furniture, but also used in Eernmeldeschräken and the like. Opposite to other known pull-out designs in which the bearings of the rollers by more than the diameter of these Rollers are offset according to the height, with cooperating between the roller areas in both profiles Stop flanges are provided, pull-out guides of the type in question have, in principle, an extremely simple construction and allow a low overall height, although the sometimes necessary tilting or complete Attacks preventing pulling out of the furniture part can be attached. You can also use the die Insert end position determining notches in that one in the running surfaces corresponding indentations or

Provides recesses. By only looking at the top or>

at the bottom of the outer circumference of the front sides of the rollers, there are options for engagement with the adjustable rollers relative to the rollers Provides profile rails, you want to prevent that when tilting the pull-out furniture part of the light and free running of the rollers by surface engagement of their end face with the web part of the relative to them moving profile is hindered and therefore the entire pull-out guide is stiff. Tilting occurs Especially with furniture parts that are wider than deep, if the force used to pull out or push in: does not act exactly parallel to the pull-out guide, whatever the Pail * will be when a drawer or the like. not exactly is handled in the middle. |

TJm the possibility of engagement between the roller face | side and to limit the profile rail movable relative to it, it is known to use frustoconical rollers and, moreover, to arrange the axes of rotation of these rollers J inclined downwards with respect to the horizontal. ϊ For this purpose, the webs of the profile rails can be provided with crankings, the inside of which is normal to the desired course of the axis of rotation. From a manufacturing point of view, such a pull-out guide is difficult to manufacture, since, for example, no simple drawn or rolled profiles can be processed immediately to form the rails, but the aforementioned cranks must be attached. Conical rollers are also more laborious to manufacture than cylindrical rollers. When tilting, there is only point contact between the edge of the roller face and the vertical webs of the profile rails, so that braking of the roller is practically prevented and the roller can continue to run during further adjustment of the pull-out guide, so not significantly in relation to your adjusted rail grinds.

To solve the same problem are also, Various other constructions have been proposed, but these are significantly more complex than the construction described and are not always fully functional. In one of these known constructions, rollers are used with, for example, a tread with a semicircular cross-section and mounted on sharply inclined axes, whereby a C-rail on the fixed furniture part as a guide for these rollers attached to the pull-out furniture part serves, which has a flat running surface on its lower leg and a concavely curved track on the upper leg forms. This path should then interact with the rollers when the drawer or the like., Is pulled out and begins to tip over. Since the castors are provided on the pull-out furniture part, they must be close together in the rear Area of the extendable part can be provided in order to prevent them from being pulled out of the guide rail too soon step out. This pull-out guide is therefore unsuitable for many applications.

There are also known drawer guides with strongly conical rollers that engage in precisely matched profiles, so that there is a form-fitting lateral association between the rollers and the guide profiles. A Canting can not occur here at all. For every Running roller, a separate guide channel is required in the guide profile over the entire length.

The object of the innovation is to improve a pull-out guide of the type mentioned so that with much simpler ones A means than before when tilting prevents the rollers from blocking.

The problem posed is achieved in that the profile rails molded stop strips or the like. for the edge area of the roller end faces. ψ

According to the innovation, you can therefore use conventional rollers and also use them in a conventional manner to move horizontal '

Transverse axes or around to the webs of the profiles supporting them store vertical transverse axes rotatably, so that no change in the profile shape in the mounting area of the pivot bearing becomes necessary.

Uach a training, the run-up bars are in Transition area between the web and flange of the profile rails formed with a vertically running contact surface. It the desired effect can therefore be achieved by a simple, continuous profile change.

The subject of the innovation is illustrated in the drawing, for example. It shows:

Fig. 1 shows an embodiment in an almost completely pushed-in position from the side with which it is attached to the drawer will,

Pig. 2 a section along the line II-II of the jig. 1 and FIG. 3 shows a section along the line III-III in FIG. 1.

The pull-out guide consists of two profile rails 1 and 2. The profile rail 1 has one in its basic shape C-shaped cross-section, the inside 3 of the lower flange 4- a running surface for a bearing on the profile 2 Roller 5 forms.

In the transition area between the web 6 of the profile rail 1 and the upper flange 7 there is no sharp corner, but a crank 8 is provided so that a stop bar 9 is formed in the profile opening, with its end face 10 the top point of the roller 5 then come into engagement can, if it comes to a tilt when pulling out. Another pull-out guide 1, 2 is symmetrical in mirror image also on the second long side of a drawer or the like. arranged.

The profile rail 2 has a Z-shaped profile, wherein the lower flange 11 is attached to the drawer from the underside, the web 12 runs approximately vertically and in the transition area to a flange 13 again a crank 14 is formed with a vertically extending contact surface 15, which when tilting cooperates with the uppermost point of a supported by the profile 1, rotatable roller 16. The flange 13 engages in the opening of the profile 1.
