Abstract
A remote controller disclosed herein may be usable in a device for adjusting the angle at which the headlight beams from a motor vehicle are directed down onto the road surface. It comprises a guide case, a slide member mounted to the guide case for axial movement but against rotation with respect to the guide case, and a rotatable shaft rotatably mounted to the guide case for rotation but against axial movement with respect to the guide case. The slide member is adjusted by the rotatable shaft which engages with a threaded portion formed on the slide member. In order to limit the extent of axial movement of the slide member, the extent of rotation of the rotatable shaft is limited by a stop fixed to the rotatable shaft and abutment means fixed to the slide member and cooperating with the stop.
Claims6
A remote controller comprising:
- a guide case;
- a slide member mounted on said guide case for axial movement but against rotation with respect to said guide case, said slide member having a threaded portion;
- a rotatable shaft rotatably mounted on said guide case for rotation but against axial movement with respect to said guide case, said rotatable shaft having a threaded portion in engagement with the threaded portion of said slide member for adjusting the position of said slide member with respect to said guide case;
- means for limiting the extent of rotation of said rotatable shaft with respect to said guide case to limit the extent of axial movement of said slide member with respect to said rotatable shaft;
- said slide member being of hollow construction, and said limiting means including a stop member fixed to said rotatable shaft and disposed in the interior of said slide member;
- first abutment means fixed to said slide member at a location adjacent to an end thereof and cooperating with said stop member and second abutment means fixed to said slide member at a location remote from said end thereof and cooperating with said stop member, said first and second abutment means being in the form of projections extending into the interior of said slide member.
A remote controller in a headlight beam adjusting device for a motor vehicle having a body and a headlight, the headlight beam adjusting device having pivotal mounting means for pivotally mounting the headlight on the vehicle body, means for biasing the headlight in one direction of tilt, and cable means connected at one terminal thereof to the mounting means for pulling the headlight in the opposite direction, the remote controller comprising:
- a guide case;
- a slide member mounted on said guide case for axial movement but against rotation with respect to said guide case, said slide member having a threaded portion;
- a rotatable shaft rotatably mounted on said guide case for rotation but against axial movement with respect to said guide case, said rotatable shaft having a threaded portion in engagement with the threaded portion of said slide member for adjusting the position of said slide member with respect to said guide case;
- means for limiting the extent of rotation of said rotatable shaft with respect to said guide case to limit the extent of axial movement of said slide member with respect to said rotatable shaft;
- said slide member being of hollow construction, and said limiting means including a stop member fixed to said rotatable shaft and disposed in the interior of said slide member;
- first abutment means fixed to said slide member at a location adjacent to an end thereof and cooperating with said stop member at a location remote from said end thereof and cooperating with said stop member, said first and second abutment means being in the form of projections extending into the interior of said slide member.
