专利汇可以提供Sliding potentiometer with a slider movable by a roller gear专利检索，专利查询，专利分析的服务。并且A sliding potentiometer including a slider movable by a roller gear, which slider electrically connects a resistance strip and a contact strip with each other, the roller gear being drivingly connected to a rack arranged in parallel to the resistance strip by means of a pinion coupled to the roller gear. The potentiometer is provided with means for uncoupling the drive connection of the roller gear in the thermal areas of the roller gear''s path of motion and means for limiting the translational movement of the roller gear in the terminal areas of the roller gear''s path of movement.，下面是Sliding potentiometer with a slider movable by a roller gear专利的具体信息内容。

权利要求

1. Sliding potentiometer comprising a slider movable by a roller gear, the slider electrically connecting a resistance strip and a contact strip with each other, drive means for coupling the roller gear to a rack arranged in parallel to the resistance strip, the drive means including a pinion provided on the roller gear for rolling on the rack, and means for uncoupling the drive means in the terminal areas oF the roller gear''s path of motion and for terminating the translational movement of the roller gear independently of the rotational movement thereof.

2. The sliding potentiometer in accordance with claim 1, characterized in that the rack (12) is shorter than the range of motion of the roller gear axis in such a manner that the pinion (11) comes out of gear with the rack (12) at the end of the range of movement of the roller gear (3).

3. The sliding potentiometer in accordance with claim 1, in which the roller gear moves a slider-supporting carriage in a straight guide parallel to the resistance strip, characterized in that the carriage (14) is provided with flexible tabs (27) which project in its directions of movement and which come to lie resiliently against an abutment surface (30) at the terminal points of the carriage''s path of motion.

4. The sliding potentiometer in accordance with claim 3, characterized in that the flexible tabs (27) of the carriage (14) begin to lie against the abutment surface (30) while the pinion (11) is in engagement with the rack (12).

5. The sliding potentiometer in accordance with claim 3, comprising a carriage with a cross-section which is U-shaped perpendicularly to the direction of movement, characterized by the yoke (19) of the U-shaped carriage (14) being prolonged in the direction of the carriage'' s movement and constituting a part of the straight guide (13, 26) of the carriage (14).

6. The sliding potentiometer in accordance with claim 5, characterized in that it exhibits at least one groove (13) extending in the direction of movement of the carriage (14) into which lateral tabs (26) of the yoke prolongation (24) engage.

7. The sliding potentiometer in accordance with claim 3, characterized by the carriage (14) and the slider (15, 16, 17, 18) being manufactured in one piece.

8. The sliding potentiometer in accordance with claim 3, characterized in that the carriage (14) includes means for acting upon the roller gear for braking and impeding the rotation thereof.
