Embodiment Construction

[0027] figure 1 and figure 2 A linear guide is illustrated generally designated with the reference number 1 , comprising a guide unit 2 and a guide element 3 which is designed in the manner of a slide and can therefore also be referred to as a guide slide. The guide unit 2 has a longitudinal shape with a longitudinal axis 4 , wherein a guide element 3 is movably mounted on the guide unit 2 for carrying out a linear movement 5 directed in the same direction as the longitudinal axis 4 .

[0028] Preferably, the guide unit 2 contains a one-piece carrier body 6 made of metal, wherein an aluminum material is particularly recommended as material or raw material. Furthermore, the guide unit 2 contains two guide rails 7 , which are fastened to the carrier body 6 in a non-positive manner in the region of the crimp connection and each have at least one guide surface 8 for linearly guiding the guide element 3 .

[0029] The carrier 6 has a linear extension, likewise each of the two ra...

Abstract

Proposed is a linear guide device (1) which has a support body (6) and at least one guide rail (7) fastened to the support body (6) by being pressed in. The guide rail (7) has a fastening portion (37) which is pressed into a fastening groove (35) of the support body (6). The fastening groove (35) is delimited by a first groove flank (35a) which is formed by a rigid counterbearing portion (28) of the support body (6). Furthermore, the fastening groove (35) is delimited by a second groove flank (35b) which is formed on a clamping leg (32) which is arranged so as to be bendable in the manner of a bending beam with respect to the support body (6). During the pressing of the fastening portion (37) into the fastening groove (35), the clamping leg (32) is bent in a resiliently elastic manner and thereby builds up a clamping force which fixedly holds the fastening portion (37).

Description

technical field [0001] The invention relates to a linear guide with a carrier body and at least one guide rail fastened to the carrier body, which guide rail has at least one guide surface for an associated guide element during operation, wherein a At least one fastening groove having a linear extension with a longitudinal side groove opening and two opposite first groove sides and a second groove side at a distance from the longitudinal direction of the groove, and wherein the guide rail is fixed by means of a The segment is pressed into the fastening groove through the groove opening and clamped between its two groove sides. Background technique [0002] A linear guide of this type known from document DE 102 49 974 A1 comprises a solid carrier body with fastening grooves formed therein, wherein the groove sides flanking the fastening grooves are rigid sections of the carrier body made of. The fastening groove has a slightly smaller width than the guide rail, which is pre...
