A mounting hole 3 for a mover unit 11, which will be described later, is formed in the groove 2 substantially at the center in the longitudinal direction. A plurality of recesses 6 are formed in the groove bottom surface 4 of the groove 2 in a portion where the mounting hole 3 is not located, and a suction plate 5 made of a long iron plate (ferromagnetic material) is fitted into the king portion 6. There is.

As shown in FIGS. 2 and 3, a mover unit 11 mounted in a case 12 whose one side surface is open has a mounting plate 13 also serving as a yoke and a coil 14 containing an iron core, as shown in FIGS.
Are arranged in a row and three magnetic sensors 15 are arranged in the center thereof, and the mounting plate 13 is fixed in the case 12 by a fastening screw 16. The lower ends of the coil 14 and the magnetic sensor 15 are located inside the opening 17 provided on the bottom surface of the case 11. Further, a controller (not shown) is mounted in the case 12. The case 12 is fitted into the mounting hole 3 of the kamoi 1 from below and is fixed by a fastening screw.

As shown in FIGS. 2 to 4, a mounting groove 22 is formed on the upper end surface of the fitting 21 over the entire length. A stator unit 23 is mounted in the mounting groove 22. The case 26 of the stator unit 23 is an extruded aluminum product, and includes a magnet loading portion 24 and a stopper block loading portion 2
5 is integrally molded. A plurality of permanent magnets 27, which are magnetized in the thickness direction and are arranged with their polarities different from each other adjacent to each other, are attached to the magnet charging portion 24. The yoke 28 is made of iron.
It is charged with. Rollers 29 are attached to the left and right sides of both ends of the magnet charging portion 24 so as to come into contact with the groove bottom surface 4 of the kamoi 1 and roll.

A stopper block 31 fixed to a fixed plate 30 is inserted into the stopper block insertion portion 25 of the case 26. The height dimension of the stopper block 31 is smaller than the height dimension of the stopper block loading portion 25. Therefore, the fixing plate 30 is attached to the fitting 2
By fixing to both ends of the first mounting groove 22, the stator unit 23 is mounted in the mounting groove 22 of the fitting 21 in a state in which it can be moved up and down by the difference in height. The position of the fixing hole of the stopper block 31 fixed to the fixing plate 30 is vertically eccentric, and the stopper block 31 is turned upside down.
The vertical movement position of can be adjusted in the vertical direction. Further, the fixed plate 30 and the stopper block 31 may be integrally molded.

In the automatic opening / closing apparatus for a fitting according to the first embodiment, when the fitting 21 is fitted into the groove 2 of the kamoi 1 and attached, the stator unit 23 has the magnetic force of the permanent magnet 27 and the iron core of the attracting plate 5 and the coil 14. The roller 29 attached to both sides of the magnet charging portion 24 of the case 26 comes into contact with the groove bottom surface 4 of the groove 2 of the Kamoi 1. As a result, the gap between the stator unit 23 and the mover unit 11 is kept substantially constant. When an open / close switch (not shown) is operated, the controller detects each coil 14 of the mover unit 11 based on the relative position between the coil 14 detected by the magnetic sensor 15 and the permanent magnet 27.
Switch the energizing direction to the power switch at the right time. This allows
The iron core of each coil 14 is attracted and repelled with respect to the polarity of the permanent magnet 27, and a force in a predetermined direction is applied to the mover unit 1.
The fitting 21 that acts between the stator unit 23 and the stator 1 and slides in the groove 2 is automatically opened and closed.

As described above, the mounting hole 3 is formed in the groove 2 of the kamoi 1.
To fix the mover unit 11 and form the mounting groove 22 on the upper end surface of the fitting 21 to mount the stator unit 23 in which the permanent magnet 27 is inserted. Opening and closing fittings can be automated. Since the mover unit 11 and the stator unit 23 are separated, the fitting 21 can be easily attached and detached without using a special tool or the like. Further, since the roller unit 29 which is in contact with the groove bottom surface 4 of the groove 2 of the duck 1 and rolls between the mover unit 11 and the stator unit 23 is held at a substantially constant interval, the opening / closing of the fitting 21 is fixed. It can be done smoothly with thrust. Further, on the portion of the groove bottom surface 4 of the kamoi 1 where the mover unit 11 is not located, the attraction plate 5 made of a ferromagnetic material is provided.
Since the stator is fixed to the roller 29,
Is held in contact with the groove bottom surface 4 of the kamoi 1. Therefore, it is not necessary to adjust the position between the mover unit 11 and the stator unit 23 when attaching the fitting 21.

(Second Embodiment) The automatic opening / closing apparatus for fittings according to the second embodiment is different from that of the first embodiment in the shape of the fitting 41 and the stator disposed on the upper end surface of the fitting 41. Other configurations are the same. Therefore, the same components are denoted by the reference numerals used in the first embodiment, and detailed description will be omitted. As shown in FIGS. 5 to 7, in the present embodiment, the stator unit 53 is separated from the fitting 41, and
A magnet catcher 43 is mounted in a mounting hole 42 formed in the substantially center of the upper end surface of the magnet with the engaging teeth 44 facing upward. The mounting hole 42 is formed in a depth such that the magnet catcher 43 can move up and down by at least the height of the engaging teeth 44. A holding plate 45 is fastened to the mounting hole 42 to prevent the magnet catcher 43 from falling off.

Further, the case 52 of the stator unit 53
Is an extruded aluminum product, and rollers 59 are provided on both left and right sides of both ends of the magnet charging portion 54 so as to come into contact with the groove bottom surface 4 of the groove 2 of the kamoi 1 and roll. A plurality of permanent magnets 2 that are magnetized in the thickness direction and are arranged with their polarities different from each other are arranged in the magnet insertion portion 54.
7 is inserted together with an iron yoke 28. A magnet catcher 55 is fixed to the substantially lower surface of the stator unit 53 with the engaging teeth 56 facing downward. The magnet catchers 43 and 55 have the engaging teeth 4 respectively.
4 and 56 are repulsed at a position where they are not engaged with each other, and are magnetized so that they attract each other at a position where they are engaged.

In the stator unit 53, the magnetic force of the permanent magnet 27 acts on the attracting plate 5 and the iron core of the coil 14 to be attracted thereto, and the rollers 59 attached to both sides of the magnet loading portion 54 of the case 52 are covered. The bottom surface 4 of the first groove 2 is in contact with the groove 2. When the fitting 41 fitted in the groove 2 of the kamoi 1 is slid toward the stator unit 53, the magnet catchers 43 and 55 approach each other. The magnet catchers 43 and 55 repel at the positions where the engaging teeth 44 and 56 are not engaged with each other, so that the magnet catcher 43 falls into the mounting hole 42. Then, when the engaging teeth 44 and 56 move up and down to the engageable position,
The magnet catchers 43 and 55 attract each other,
The magnet catcher 43 floats and the engaging teeth 44 and 56
Engage. Thereby, the fitting 41 and the stator unit 5
3 is connected, and the fitting 41 can be automatically opened and closed as in the case of the first embodiment.

As described above, in the automatic opening / closing apparatus for a fitting according to the second embodiment, the stator unit 53 is separated from the fitting 41, and the fitting 41 and the stator unit 53 are connected to each other by the engaging teeth of the magnet catchers 43 and 55. 44 and 56 are engaged with each other, and the fitting unit 41 is fitted into the groove 2 and slidably brought close to the stator unit 53 arranged in the groove 2 of the kamoi 1, Can be connected to. Further, since the fitting 41 and the stator unit 53 can be separated, the fitting 41 can be easily attached and detached without using a special tool or the like. Further, since the roller unit 59 that abuts on the groove bottom surface 4 of the duck 1 and rolls between the mover unit 11 and the stator unit 53 is held at a substantially constant interval, the opening and closing of the fitting 41 can be smoothly performed with a constant thrust. Can be done.
