The hanging door can be opened and closed without rolling.

〔Example〕

Hereinafter, a guide rail device for a suspension door according to the present invention will be described based on an illustrated embodiment.

In the figure, reference numeral 1 denotes a guide rail piece which suspends a hanging door D from an upper rail R to accurately guide the hanging door D, and is buried and fixed to a floor surface.

For example, as shown in FIG. 8 and FIG. 9, when the hanging door D is fully opened,
An indentation is formed in the floor so that the sheet is fed out one by one and finally in a row, and fitted into the indentation.

Therefore, the guide rail piece 1 is substantially flush with the floor when the hanging door D is open.

The guide piece 1 has a cylindrical outer cylinder 1A having a mounting flange 11 on the upper outer periphery, as in the reference example shown in FIGS. 1 to 5,
A projection 1B is inserted into the outer cylinder 1A so as to be able to protrude and retract, and a permanent magnet 1C having a required magnetic force is also fitted to the top of the projection 1B.

In the longitudinal direction of the lower outer periphery of the projection 1B, a ridge 14 is formed.
Are provided, and the top surface of the ridge 14 is engaged with the step surface 13 formed on the inner peripheral surface of the outer cylinder 1A, thereby restricting the amount of protrusion of the protrusion 1B in the upward direction.

In addition, a guide hole having a long hole shape is formed on the outer circumference of the outer cylinder 1A in the vertical direction.
When the projection 1B is inserted into the outer cylinder 1A and the projection 1B is inserted into the outer cylinder 1A, the guide pin 15 projecting substantially horizontally is inserted into the projection 1B. Is regulated in the outer cylinder and the amount of protrusion and retreat.

In addition, as shown in FIG. 2, the protruding body 1B is in a state where the top surface is substantially flush with the outer cylinder top surface or is in a sunk state so as to protrude only slightly, or a magnet is provided on the excitation material above the guide rail piece. When it acts on it, it rises by its magnetic force. The flange 11 of the outer cylinder 1A has a screw hole for attachment to the floor.
16 can also be drilled.

By the way, as shown in the embodiment shown in FIGS. 6A and 6B, the projection 1B is provided with a pin 17 which is pressed toward the outer cylinder 1A by receiving the urging force of the spring. When the projection 1B is projected, the pin 17 is pressed against the outer cylinder 1A by receiving the urging force of the spring, so that the projection can be maintained in the projected state.

The embodiment shown in FIG. 7 uses an outer cylinder 1A and a projection 1B fitted into the outer cylinder 1A, which are configured in the same manner as the reference example shown in FIGS. The exciter 16 is embedded in a part of the wall, and the magnet piece 17 is embedded in the protruding body 1B at a position where the exciter 16 and the extruding body 1B protrude. Exciting body 16 in cylinder 1A
The same effect can be obtained by providing the projection on the projection 1B.

With this configuration, when the hanging door D comes to the floor surface position where the guide rail piece 1 is embedded, the long groove rail piece provided on the lower surface of the hanging door protrudes due to the attracting action of the magnet of the projection.
As a result, the protrusion 1B is inserted into the concave groove of the long groove rail piece, and the outer cylinder, the magnet 17 and the exciter 16 of the protrusion are attracted to each other and pass through the exciter position on the lower surface of the suspension door. The protrusion 1B of the body 1B is maintained in a protruding state by the attraction force of the magnet 17 and the exciting body 16. For this reason, the exciter provided on the lower surface of the suspension door is provided only at the leading end position of the suspension door, and there is no need to provide the exciter behind the intermediate portion, thereby making it unnecessary to use the entire long groove rail piece as the exciter. Production of long groove rail pieces becomes easy.

In the embodiment shown in FIG. 16, the outer cylinder 1A has a cylindrical shape longer than those of the above embodiments, and a flange 11 is integrally formed on the outer peripheral portion of the upper end, and the protrusion 1B can be freely protruded and retracted in the outer cylinder 1A. Magnets 1C and 1D respectively on the top and bottom of this cylindrical projection 1B.
Are provided integrally with each other, and a vertically elongated hole-shaped guide hole 12 is formed in the projection 1B, and a fixing pin 18 fitted and fixed to the outer cylinder 1A is inserted into the guide hole 12, and the guide hole 12 is formed. The inner cylindrical projection 1B is slid vertically by the length of the guide hole 12 with the fixing pin 18 so that the inner cylindrical projection 1B protrudes and retracts from the outer cylinder 1A.

A case 19 is inserted into the inner cylindrical projection 1B, and the case 19 is supported by a fixing pin 18 and a magnet 1E is fitted into the case 19, and the magnet 1E and the magnet 1D are attracted to each other. So that the magnets 1E and 1D have the required attraction force with the protrusion 1B protruding to the maximum, as long as no pressing force other than the attraction force by the magnets 1E and 1D acts on the protrusion 1B. Do not descend, that is, sink into the outer cylinder 1A.

In this embodiment, the inner cylindrical projection 1B and the magnet
1C can be a square as shown in FIG. 16 (C), a quadrangle, or a quadrangle or a polygon in which each side is an arc with a large angle as shown in FIG. 16 (D). . The operation of this embodiment is the same as the above embodiments.

In each of the above embodiments, the outer cylinder 1A and the protrusion 1B are manufactured by a non-excited body.

A long groove is formed on the lower end surface of the hanging door D in the traveling direction of the hanging door as shown in FIG.

This is constituted by forming the long groove rail piece 2 entirely or partially using a material made of an exciter and embedding it in the lower end of the suspension door.

The long groove rail piece 2 forms an inclined introduction portion 21 at both ends when attached to the hanging door D, and the intermediate portion 22 is determined to have a required depth, that is, a projection 1B of the guide is fitted. As shown in FIG. 12, the one introduction portion 21 is a swinging floor, and the tip of the swinging piece 23 is in contact with the floor surface by its own weight.
1C is more surely excited and protruded.

And, when the suspension door D passes through the guide rail piece position, the inclined surface 24 at the rear end pushes down the projection top face of the guide rail piece so that the projection body is immersed in the outer cylinder.

14 to 15 show a reference example of a guide rail piece, in which a head 31 provided with a magnet is fitted in a flanged outer cylinder case 30 so as to be able to protrude and retract, and is swingable on an axis 32 in the outer cylinder case 30. A link 33 pivotally attached to the head is also fitted, the tip of the link 33 is locked to a part of the head, and the link is swung by raising and lowering the head to guide the head. The operation is the same as in the other embodiments.

〔The invention's effect〕

According to the guide rail device of the suspension door of the present invention, since the guide rail pieces with magnets are embedded in the floor surface and the long groove rail pieces with excitation pieces are embedded in the lower end of the suspension door, the floor surface is clean, When there are no protrusions and the hanging door is closed,
Since the magnet of the guide rail piece protrudes and is fitted into the long groove of the hanging door by the long groove rail piece, the hanging door can travel reliably along the upper rail, and can perform the anti-sway action, and furthermore, the hanging door can be used. After the passage, the protrusion of the guide rail piece is automatically immersed in the outer cylinder, which has an advantage that the protrusion is eliminated on the floor surface. In particular, at the projecting position of the projection, a holding mechanism for the projection is provided so that the projection is not lowered unless the projection is pushed down by the inclined surface of the long groove rail piece. This is advantageous in that it is simple and the swing door can be more reliably stopped.
