Abstract
An automatic sliding door cable mechanism with a take up guide member (46) mounted in a drum (14) for taking up slack of a cable during installation of the cable. A second drum (16) has an elliptical profile drum helix (96) for increasing durability of the operating cable for the automatic door.
Claims12
A take-up guide cable tensioning system comprising:
- a first take-up drum having an outer surface for pulling a cable in a first direction;
- a second take-up drum having an outer surface for pulling the cable in a second opposite direction;
- said first and second drums operably connected to rotate together;
- said first drum having a slot under the outer surface;
- a take-up guide is slideably mounted in said slot and having spring loaded ratchet teeth normally mounted to engage complementary ratchet teeth in the slot to prevent movement of the take-up guide in one direction;
- said take up guide having a section mounted to an end of the cable and movable in a second direction in said slot to take up slack in said cable and provide tension in said cable.

A take-up guide cable tensioning system comprising:
- a housing having apertures therethrough for allowing passage of a cable therein and tool access therethrough;
- a first take-up drum having an outer surface for drawing the cable in a first direction rotatably mounted in said housing;
- a second take-up drum having an outer surface for drawing the cable in a second opposite direction rotatably mounted in said housing;
- said first and second drums operably connected to rotate together;
- a spring loaded pulley being mounted in a housing for providing a spring-loaded tension on said cable;
- a tool constructed to be passed into at least two of said apertures in said housing for rotating said first drum with respect to a take up guide and for limiting the compression of said spring loaded pulley.

A take-up guide cable tensioning system comprising:
- a take-up drum having an outer surface for pulling a cable in a first direction;
- said take-up drum having a slot under the outer surface;
- a take-up guide is slideably mounted in said slot and having at least one spring loaded ratchet tooth normally mounted to engage complementary ratchet teeth in the slot to prevent movement of the take-up guide in one direction;
- said take up guide having a section mounted to an end of the cable and movable in a second direction in said slot to take up slack in said cable and provide tension in said cable.
