DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic opening / closing apparatus for fittings which can be opened and closed by a linear DC motor for moving fittings along a groove of a gate.

[0002]

2. Description of the Related Art Various automatic opening / closing devices for fittings using a linear motor have been proposed.

However, these conventional devices require special processing of a door frame for new construction or renovation, and prior mounting of a mounting bracket to a mounting portion (inside a wall) of the device. In addition, the linear DC motor, which is a door engine of the conventional device, does not consider retrofitting. In order to automatically open and close the fittings, it is necessary to update the entirety including the door frame and the fittings. In addition, a tool is required to remove the fittings, and adjustment work is required even after re-attachment. Therefore, it is practically difficult for the user to remove or adjust the fittings. The present invention has been made in view of the above problems, and has as its object to provide an automatic opening / closing device for a fitting that can be easily attached to an existing fitting.

[0004]

According to a first aspect of the present invention, there is provided an automatic opening / closing apparatus for a fitting, wherein a movable coil type linear motor is fixed to an upper end of a fitting movable along a groove of a Kamoi. An automatic opening / closing device for a fixture, comprising a movable member fixed to a dolly and a movable member relatively movable with respect to the stator, wherein the movable member is disposed on an upper end side surface of the fitting. The child is swingably supported in a direction orthogonal to the moving direction of the fitting through a bracket fixed to the duck, and is urged by a spring in a direction in which the child is always in contact with the stator. And the gap between the stator and the mover is kept constant.

According to a second aspect of the present invention, there is provided an automatic opening and closing device for a fitting, wherein the fixture and the movable element are formed so as to have an arc-shaped cross section and conform to the fitting. Is characterized by being curved.

[0006]

According to the apparatus for automatically opening and closing a fitting according to the first aspect, the movable element supported so as to be swingable in a direction orthogonal to the direction of movement of the fitting via a bracket fixed to the gate is: The spring constantly urges the stator in a direction in which it comes into contact with the stator, and the gap between the stator and the mover is kept constant via rollers provided on the mover. Therefore, both the mover and the stator can be retrofitted to existing fittings using general tools. Also, when the fittings are removed from the door, it is not necessary to disassemble the mover, etc., and it is not necessary to adjust the position between the mover and the stator after fitting the fittings to the door, so the existing fittings can be easily replaced. The fitting can be automatically opened and closed.

According to the apparatus for automatically opening and closing fittings according to the second aspect, since the stator and the mover are curved so as to match the fittings having an arcuate cross section, the fittings having an arcuate cross section can be easily automatically opened and closed. Can be.

As shown in FIG. 2, the stator 11 includes a stator case 12, a permanent magnet 13, a yoke 14, and a rail member 15.

The stator case 12 is an extruded product made of a non-magnetic material such as aluminum, and has a pair of locking legs 1 over its entire length.
2a is integrally formed. Inside, a plurality of permanent magnets 13 magnetized in the thickness direction are arranged over the entire length together with an iron yoke 14 with different polarities between adjacent magnets. The rail member 15 is also a non-magnetic extruded product such as aluminum, and has a mounting groove 16 and locking protrusions 17 integrally formed on both sides of the mounting groove 16 over the entire length. Then, the rail member 15 is horizontally fixed to one side surface of the upper end of the sliding door 3 by a fastening screw 18, and the mounting groove 16 is fixed.
The stator 11 is constructed by mounting the stator case 12, the permanent magnet 13, and the yoke 14 from one end of the stator 11.

A mover unit 21 of a coil movable linear motor L includes a set of three magnetic sensors 24 and a plurality of iron cores in a horizontally bent plate portion 23 of a suspension body 22 bent in an L shape. Are mounted in a row in the longitudinal direction, and rollers 26 are mounted on the left and right ends of the horizontal plate portion 23 so as to roll in contact with the stator case 12. The hanging body 22 is provided with the vertically bent plate portion 2.
