    Abstract: A gate assembly includes a sliding gate, a drive having a motor and motor pinion gear for driving the sliding gate, and a force transmission element for transmitting a driving force from the drive to the sliding gate. The force transmission element includes at least one threaded bolt having a bolt head, and a toothed rack engaged with the motor pinion gear. The toothed rack includes a toothed element having a base defining a first side having teeth attached thereto, and a second side opposite to the first side and forming a groove extending in a longitudinal direction of the toothed element for accommodating the bolt head. The groove defines a groove width corresponding to a width of the bolt head. The toothed rack further includes a support element connected with the sliding gate using the at least one bolt, and that is adapted to receive the toothed element. The support element includes at least one through bore for receiving the at least one bolt.

    Abstract: A retractable door structure for a storage case including a pair of guide grooves formed from the front end to the back end of the inner surfaces of the case panel, sliding blocks connected to each other by a connecting rod provided in the guide grooves, and a pinion mounted in each of the sliding blocks which is designed to engage with a rack formed in the guide grooves. The door is pivotally held between the sliding blocks by rotary shafts attached to the corners of the door. By means of this structure, the door can be slid inside the case after it is opened and the door is easily pushed in and pulled out of the case since the sliding blocks holding the door slide smoothly in the guide grooves.

    Abstract: The torsion spring winding device of the present invention comprises a gear having annular teeth thereon and additionally having means for detachably securing the gear to the free end of a torsion spring. A worm gear support is rotatably mounted to the gear so as to permit the gear to rotate independently of the worm gear support. The worm gear support carries an elongated worm gear in driving engagement with the annular teeth of the gear, and additionally includes a stop means for engaging the wall upon which the torsion spring is mounted. The method of the present invention comprises attaching a rotatable gear member having a plurality of peripheral teeth thereon to the free end of a torsion spring, engaging the peripheral teeth of the gear member with a worm gear, holding the worm gear mechanism against swinging movement with respect to the spring whereby the worm gear prevents rotation of the gear member and the free end of the spring with respect to the fixed end of the spring, rotating the worm gear to drive the gear member in a rotational direction whereby the free end of the torsion spring is rotated with respect to the fixed end thereof, and detaching and removing the gear member from the spring.

    Abstract: A door open and close mechanism for opening and closing a plurality of doors in a machine tool including a cover. The door open and close mechanism includes a linkage mechanism and a slide mechanism. The linkage mechanism is disposed between an operation door and an intermediate door. The linkage mechanism associates the intermediate door with the opening and closing of the operation door. The slide mechanism is disposed between the operation door and the linkage mechanism. The slide mechanism enables the operation door alone to open and close by a predetermined moving distance. When the operation door is operated to open and close within the moving distance, the operation door alone opens and closes by the slide mechanism. When the operation door is operated to open and close beyond the moving distance, the intermediate door opens and closes in association through the linkage mechanism.
