Abstract

The opening-closing mechanism according to the present invention, consists of a bearing track (2), a spring (3) placed in said track (2), a pinion (4) providing its reciprocating movement on said spring (3); a motor drive shaft (5) providing the connection of said parts with the source of movement, a core bar (hub spindle) (6) to balance the spring (3) and two bearing bushes (7).

Claims

1. An opening/closing mechanism, consisting of a bearing track (2), at least one spring (3) placed in said track (2), bearing bushes (7) provided at both ends of the bearing track (2) which enable said spring (3) to be placed inside the track (2) a motor drive shaft (5) one end of which is attached to one of said bushes (7) in order to transmit movement to the spring (3) and the other end on which said spring (3) is wound, and a hub spindle (6) that serves to balance said spring (3) attached onto one of said bushes;

characterized with a pinion (4) attached on the spring (3) and which moves inside the bearing track (2) when said spring (3) is driven by the motor.

2. An opening/closing mechanism as defined in claim 1, characterized with a pinion (4) that provides the opening/closing movement by means of a magnetic action, due to a magnetic part fastened on it.

3. An opening/closing mechanism as defined in claim 1, characterized with a pinion (4) that provides the movement by getting into direct contact with the object that is desired to be moved.

4. An opening/closing mechanism as defined in claims 1 to 3, characterized with a bearing track (2) that enables the linear and angular movement of the object that is desired to be moved.

5. An opening/closing mechanism as defined in claims 1 to 4 wherein the object that is desired to be moved is a door.

6. An opening/closing mechanism as defined in claims 1-4, wherein the object that is desired to be moved is a curtain rail roller.
