Abstract

A guide carriage of a linear guide, which guide carriage has a back ( 1 ) and legs ( 2 ) bent away from the back ( 1 ) and disposed along a longitudinal axis of the guide carriage for engaging over a guide rail ( 7 ), the two legs ( 2 ) are each provided with a longitudinal seal ( 5 ) having rod-shaped bodies ( 12 ) each of which has a sealing lip ( 8 ) on sides facing one another. The rod-shaped body ( 12 ) is supported on an abutment ( 9 a ) of the leg ( 2 ) provided along the longitudinal axis, wherein the rod-shaped body ( 12 ) is retained on the guide carriage together with the two axial rod ends ( 13, 15, 18 ) of the rod-shaped body ( 12 ) and is spring-loaded against the abutment ( 9 a ) by means of the inherent spring force of the rod-shaped body ( 12 ).

First claim

1 . A guide carriage of a linear guide, said guide comprising a back side and two legs that are angled away from the back side and arranged along a longitudinal axis of the guide carriage for gripping around a guide rail, the two legs are each provided with a longitudinal seal having rod-shaped bodies which each have a sealing lip on sides facing each other, the rod-shaped bodies are each supported on an abutment of the leg provided along the longitudinal axis, and each of the rod-shaped bodies is held with two axial rod ends thereof on the guide carriage and is spring-loaded with an internal spring force against the abutment.

2 . The guide carriage according to claim 1 , further comprising a carrier body and head pieces arranged on both ends of the carrier body set in a direction of the longitudinal axis, and each of the longitudinal seals is held with the two axial rod ends thereof on the head pieces.

3 . The guide carriage according to claim 2 , wherein each of the sealing lips is integrally connected to a corresponding one of the rod-shaped bodies, and both of the axial rod ends of each of the rod-shaped bodies are free from the sealing lip.

4 . The guide carriage according to claim 2 , wherein the carrier body includes the two legs, and a supporting groove is formed along the longitudinal axis for holding the rod-shaped body on each of the two legs, the supporting groove is provided with first and second supporting surfaces that are arranged at an angle to each other and are extended along the longitudinal axis and on which the rod-shaped body is supported, and the first supporting surfaces of the two bearing grooves are directed toward a bottom side of the guide carriage and the second supporting surfaces face each other.

5 . A method for producing a longitudinal seal for a guide carriage according to claim 1 , in which the rod-shaped bodies are each provided with a sealing lip arranged along the longitudinal axis, the method comprises: injection molding of the rod-shaped body with the sealing lip being integrally formed along an arched, curved rod axis, with rod ends of the rod-shaped body being injection molded along a straight axis, and the arched, curved rod body produced is bent in a direction toward a straight rod axis under elastic shape changes to the rod body.

6 . The method according to claim 5 , wherein the longitudinal seal is made from a thermoplastic elastomer.
