Definitions
- the present invention relates to a linear guide with a U-shaped guide rail.
- Such linear guides can be used, for example, as drawer pull-outs.
- a linear bearing arrangement consisting of a unit which is guided between the two legs of a U-shaped guide rail.
- the unit consists of a mounting plate on which the load-bearing roller and an eccentrically guided support roller are compactly attached for adjustment.
- raceways are formed, on which the rollers roll with their outer surface.
- the material of the guide rail must be hard enough to ensure a minimum hardness of the raceways. If the guide rail of the known linear guide is made, for example, of plastic by injection molding, the problem can arise that the raceways formed on the mutually facing sides of the legs are too soft for the contact loads which are transmitted via the rollers.
- the object of the present invention is therefore to provide a linear guide according to the To provide features of the preamble of claim 1, in which this disadvantage is eliminated.
- the legs are each provided on their mutually facing sides with a steel band, the mutually facing sides of which have the raceways.
- the guide rail can advantageously be produced, for example, from aluminum in the continuous casting process, or else from plastic in the spraying process.
- the steel strips provided according to the invention have a sufficiently high hardness so that the raceways formed thereon for the rollers introduce the loads transferred from the rollers correctly and over a large area into the legs of the guide rail.
- the guide rail is preferably formed from sheet metal, and has a base and the legs which are integrally connected to the base. Such guide rails can be produced in a simple bending process.
- the steel strips provided according to the invention can be placed on the legs without any problems.
- the steel strips are preferably provided on their mutually facing sides with catwalks arranged along the guide rail and carrying the raceways. These catwalks are useful when the rollers are simultaneously provided with grooves in which the catwalks engage with their raceways. In this way, a perfect positioning of the carrier transverse to the guide rail is guaranteed.
- the catwalk can advantageously be bent out of the steel strip as a standing seam.
- a standing seam can be bent out inexpensively without additional parts being required.
- the standing seam is preferably approximately U-shaped or V-shaped when viewed in cross section educated. Folds with such a cross section can be produced in a simple manner. It is conceivable, for example, that these standing seams are formed in one rolling process.
- the legs are provided with projections on mutually facing sides, which engage in the standing seam of the steel strips.
- the projections are dimensioned in such a way that the steel strips are correctly positioned on the legs of the guide rail.
- projections can be formed as further standing seams formed in one piece from the legs formed from sheet metal and extending along the guide rail.
- a further development according to the invention provides that the bottom of the guide rail is provided on its lateral edges with a stiffening fold arranged along the guide rail.
- Such stiffening folds can also be easily formed in a bending process.
- the stiffening fold is preferably formed by folding into two sheet layers.
- the stiffening fold adjoins the leg in one piece and the bottom in one piece.
- the guide rail thus produced is light, yet stiff and at the same time inexpensive to manufacture.
- FIG. 1 shows a perspective illustration of a linear guide according to the invention
- Figure 2 shows a section of the linear guide according to Figure 1 in an exploded view
- Figure 3 shows a detail of the linear guide according to Figure 1 in an enlarged view.
- the linear guide according to the invention shown in FIGS. 1 to 3 comprises a guide rail 1 which is formed from sheet metal and has a base 2 with legs 3 integrally formed thereon.
- the legs 3 are each provided with a steel band 4 on mutually facing sides, which is arranged along the guide rail 1.
- a carrier 5 is provided, which is received on the guide rail 1 so as to be longitudinally displaceable.
- rollers 6 are rotatably arranged on axes 7, the axes being fastened to the carrier 5.
- the rollers 6 are provided with grooves 8.
- the steel strips 4 each have a catwalk 9 arranged along the guide rail 1 on mutually facing sides. These catwalks 9 are provided with raceways 10 for the rollers 6, the catwalks 6 engaging in the grooves 8 of the rollers 6. In this way, the rollers 6 are correctly positioned in their axial direction.
- the catwalk 9 is designed as a standing seam 11, the standing seam 11 being bent out of the steel strip 4. Viewed in cross section, standing seam 11 has an approximately U-shaped or V-shaped cross section.
- the legs 4 of the guide rail 1 are each provided with a further standing seam 12 which extends along the guide rail 1 and which projects in the direction of the respective other standing seam 12.
- These standing seams 12 are also formed on the legs 4 made of sheet metal by bending. These standing seams 12 engage in the standing seams 11 of the steel strips 4. on. In this way, the steel strips 4 can be easily positioned on the legs 4.
- the standing seams 11 and 12 stiffen the entire linear guide.
- a stiffening fold 13 is formed on the bottom 2 of the guide rail 1 at the lateral edges. These stiffening folds 13 are arranged along the guide rail 1. The stiffening folds 13 are formed by folding into two sheet metal layers on the bottom 2. Each stiffening fold 13 connects on the one hand to the leg 3 and on the other hand to the bottom 2 in one piece.
