Abstract
A carriage (30) for slidable movement along a track (100) having first and second parallel spaced apart guide surfaces (102, 104) is provided. The carriage (30) includes a base member (36). Structure (72, 78, 80) is mounted on the base member (36) for contacting the first and second parallel spaced apart guide surfaces (102, 104) on the track (100). The base member (36) includes a spring (50, 56, 58), such that as the base member (36) moves along the track (100), the base member (36) is resiliently compressed to thereby urge the structure (72, 78, 80) against the guide surfaces (102, 104) on the track (100).
Claims5
A carriage for slidable movement along a track having first and second parallel spaced-apart guide surfaces comprising:
- a base member having first and second edges parallel to said first and second parallel spaced apart guide surfaces, said base member having an elongated slotted aperture formed therein along said first edge thereof, said aperture defining first and second portions of said base member spaced apart thereby, said first portion supported at its ends by said second portion;
- first roller means mounted on said first portion of said base member for slidably engaging said first guide surface;
- and
- second roller means mounted on said second portion of said base member for slidably engaging said second guide surface, wherein said base member forms an integral spring for compressing said first portion of said base member relative to said second portion to thereby bias said first and second roller means against said guide surfaces to maintain the carriage in said track, and for compensating for dimensional variations in said track.
