Position sensor holder and cover for motor drive unit
First Claim
1. A position sensor and position sensor holder for use in connection with a power lift system comprising:
- a magnetically responsive position sensor; and
an elongated extruded polymeric member having at least one mounting flange for attachment to a power lift housing, said member integrally including an elongated socket for slidably receiving and holding said magnetically responsive position sensor therein, said socket and mounting flange aligned such that said position sensor holder can be secured to a power lift housing and said sensor moved along said socket for alignment with a magnet of a movable element of the power lift system for actuating the magnetic sensor when said position sensor holder is mounted to a power lift housing.

Abstract
A position sensor holder for a powered lift system includes a polymeric member having a mounting surface on one side for attachment to the housing of a lift system and an elongated socket for receiving a magnetically responsive sensor positioned on an opposite side for providing a control signal as a magnet on a movable element of the lift system approaches the sensor. In a preferred embodiment, the socket comprises a pair of upwardly extending resilient legs for snap-receiving the sensor and including an undercut for receiving a cover element which covers the sensor and wires extending along the elongated socket coupling the sensor to a control circuit for the lift system.

11. A power lift system comprising:
-
a powered screw having a threaded pusher block, said pusher block including a control element;
a housing for said powered screw, said housing slidably receiving said pusher block, said housing including an elongated slot in predetermined longitudinal alignment with said powered screw such that said control element of said pusher block extends toward said slot; and
an elongated extruded polymeric member having at least one mounting flange for attachment to said housing, said member including a socket for receiving and holding a sensor therein, said socket and mounting flange aligned such that said member can be secured to said housing such that said control element actuates said sensor when said pusher block moves into proximity to said sensor. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
