Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a guide for a hanger door that can reliably guide the hanger door without providing a guide rail or a groove-shaped rail that always projects on the floor surface. The present invention relates to a rail device.

[Conventional technology]

The suspension door is suspended and supported via a hanger by a rail fixed to the upper part, and the lower end is free end or inserted into the groove rail formed on the floor, and the suspension door is connected to the upper rail and the groove rail. It is guided to open and close.

[Problems to be solved by the invention]

When the hanging door is suspended only by the upper rail, there are no protrusions or grooves on the floor to support or guide the lower part of the hanging door. Although it is refreshing,
On the other hand, since the lower part of the suspension door is not locked to anything on the fixed side, there is a disadvantage that the lower part of the suspension door swings in a direction perpendicular to the traveling direction. Further, in order to prevent the swing of the hanging door, a rail may be laid on the floor surface, and a swing piece provided at a lower end of the hanging door may be locked to the rail. In this case, there is an effect of preventing the suspension door from swaying, but there is a rail-shaped protrusion on the floor surface, and there is a risk that the beauty of the floor surface may be impaired or the protrusion may be tripped during traveling. Further, when the groove rail is used, the rail may be tripped over, or dust may enter the groove, further degrading the beauty of the floor surface.

An object of the present invention is to form a protrusion or a concave groove such as a rail on a floor surface, and furthermore, when opening and closing a suspension door, to prevent runout and to reliably open and close the suspension door at a predetermined position. I do.

[Means for solving the problem]

The present invention has been made to achieve the above object, and a hanging door is suspended and supported via a hanger at an upper rail, and when the hanging door moves to a long groove rail piece embedded at the lower end of the hanging door. In the guide rail of the suspension door, which is adapted to insert the guide rail piece embedded in the floor surface to guide the suspension door, a long groove rail piece whose both ends are shallow and the center part is deep is provided at the lower end face in the longitudinal direction of the suspension door. It is formed integrally, an inclined bottom portion is continuously provided between the shallow groove portion and the deep groove portion, and two magnets having different polarities are embedded in the shallow groove portion, and the polarities of the magnets at both outer ends of the suspension door are matched. An outer cylinder that embeds and fixes the guide rail piece on the floor surface to the floor surface, and is inserted and inserted into this outer cylinder so as to be freely retractable,
The gist of the invention is that the top surface comprises a projection having a magnet having a polarity that repels the magnets on both outer sides of the hanging door.

[Action]

A guide rail piece provided with a magnet is provided at a predetermined interval at a position where the hanging door on the floor travels in the opening and closing direction so as to be able to protrude and retract, while a long groove on the lower surface of the hanging door into which the guide rail piece can be inserted in the traveling direction. A rail piece is formed, and the guide rail piece is immersed in the floor surface by the mutual attraction force of the magnet of the guide rail piece and the magnet buried in the long groove rail piece by a protruding and repulsive force. With this, when opening and closing the hanging door suspended on the upper rail only through the hanger, when the hanging door advances and the hanging door is located on the upper part of the guide rail piece, it will be attached to the long groove rail piece fixed to the hanging door side. The magnets of the protrusions of the guide rail pieces are attracted and the protrusions of the guide rail pieces protrude upward and are fitted into the long groove rail pieces, and the suspension doors serve as anti-sway and are accurately guided. Becomes Then, when the suspension door stops above the guide rail piece, the protruding body of the guide rail piece keeps the protruding state, but when the suspension door is moved and the guide rail piece comes to the magnet position at the end of the suspension door, it repels. Forced immersion into the floor by force, it is almost flush with the floor, and the hanging door can be opened and closed without stumbling or collecting garbage.

〔Example〕

 Hereinafter, the present invention will be described based on the 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 F. For example, as shown in FIG. 8 and FIG. 9, when the hanging door D is fully opened, a plurality of hanging doors are sent out one by one from a state where they are overlapped with each other, and finally they are arranged in a row so as to be arranged on the floor surface. A recess is formed and provided by fitting into the recess. Therefore, the guide rail piece is substantially flush with the floor surface when the hanging door is opened.

As shown in detail in FIGS. 1 to 5, the guide rail piece 1 has a cylindrical outer cylinder 1A having a mounting flange 11 on the upper outer periphery.
And a projection 1B that is inserted into and retracted from the outer cylinder 1A. The permanent magnet 1 having a required magnetic force is also fitted to the top of the projection 1B. A plurality of ridges 14 are provided in the longitudinal direction of the lower outer periphery of the projection 1B, 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. The amount of upward protrusion is regulated.

In the outer periphery of the outer cylinder 1A, a vertically long guide hole 12 is formed.
When the projection 1B is inserted into the outer cylinder 1A, a guide pin 15 projecting in a substantially horizontal direction is inserted into the projection 1B. This controls the rotation in the outer cylinder and the amount of projection. In addition, as shown in FIG. 2, the protruding body 1B is always under its own weight so that the top surface is almost flush with the top surface of the outer cylinder or only slightly protrudes, or the magnet is located above the guide rail piece. When acting on the exciting material, it rises by the magnet. Further, a screw hole 16 for attachment to the floor may be formed in the flange 11 of the outer cylinder 1A.

FIGS. 6 (A) and 6 (B) show a first embodiment, in which an outer cylinder 1A has a longer tubular shape than that of the first embodiment, and a flange 11 is integrally formed on the outer periphery of the upper end. The projection 1B is inserted and inserted into the outer cylinder 1A so that the projection 1B can come and go.
Magnets 1C and 1D are fitted to and integrated with the top and bottom of 1B, respectively, and a vertically long guide hole 12 is formed in the projection 1B, and a fixing pin 18 fitted and fixed to the outer cylinder 1A is used as the guide. The guide hole 12 and the fixing pin 18
1B slides up and down only the length of this guide hole 12, and
Make it appear at 1A. Further, a case 19 is inserted into the inner cylindrical projection 1B, and the case 19 is supported by the fixing pins 18 and a magnet 1E is inserted into the case 19, and the magnet 1E and the magnet 1D are mutually connected. The magnets 1E,
1D is made to have a required attraction force, and the projection 1B is prevented from descending, ie, sinking into the outer cylinder, unless a pressing force other than the attraction force acting on the magnets 1E and 1D acts.

In the second embodiment, the inner cylindrical projection 1B and the magnet 1C are not only circular as shown in FIG. 7 (A), but also square or each side having a large angle as shown in FIG. 7 (B). It is also possible to use a quadrangle or a polygon in the shape of an arc.

In each of the first and second embodiments, the outer cylinder 1A and the projection 1B
Is manufactured with a non-excited body.

On the lower end surface of the hanging door D, a long groove is formed 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 non-excited material and fitting it into the lower end of the suspension door. When the long groove rail piece 2 is attached to the suspension door D, both ends are formed as a shallow groove 21 and a central part is formed as a deep groove 22, and a gap between the shallow and deep grooves 21 and 22 is formed as an inclined part 23, and a deep groove at the center is formed. The portion 22 is determined so as to have a required depth, that is, the guide projection 1B is fitted.

Further, two magnets 25 and 26 having different polarities are embedded as a pair in the shallow groove portions 21 on both sides of the long groove rail piece 2, respectively, and the magnets 25 and 25 at both outer ends of the suspension door have the same polarity. Magnet 1C provided on the top surface of the protrusion on the guide rail piece
Both have the same polarity.

Although the magnets 25 and 26 may be directly buried in the hanging door, as shown, a shallow groove portion 21 and an inclined portion 23 are integrally formed in a magnet fixture 27 formed of a synthetic resin or other non-exciting magnetic metal. It is buried, and this fixture 27 is fixed in the long groove rail piece of the suspension door 2 with a screw 28.

 The magnets 26 and 1C are to be attracted to each other.

Therefore, when opening and closing the hanging door configured as described above, the hanging door is moved by pulling it along the upper rail, and when the tip of the hanging door comes on the guide rail piece 1 embedded in the floor surface, the outside of the hanging door is moved. Since the magnet 25 and the magnet 1C of the protruding body repel each other, the protruding body is in a state submerged on the floor surface. When the suspension door is further moved and the magnet 26 comes above the protrusion, a force for attracting the magnet 1C to each other acts, and the protrusion protrudes from the floor surface. Further, when the hanging door moves and the protrusion reaches the deep groove 22, the protrusion is held by the magnet 1C because the deep groove is excited. Then, when the rear end of the suspension door comes over the projection, the projection is immersed in the floor by the repulsive force of the magnets 25 and 1C. In this way, the protruding body repeats the protruding and retracting operation by the attraction and repulsion of the magnets 25, 26 and 1C for each of the hanging doors, but when the protruding body is at a position other than both ends of the long groove rail piece, the long groove rail piece is used. It is fitted inside and guides the hanging door, and after passing through the hanging door, the protrusion is forcibly pushed down to the floor surface so as not to protrude above the floor surface.

〔The invention's effect〕

According to the present invention, a guide rail piece provided with a magnet is embedded on the floor surface, and a long groove rail piece provided with a pair of excitation pieces that repels and attracts the magnet of the guide rail piece at the lower end of the suspension door. The surface is clean, and when the hanging door is inserted, the guide rail piece is securely immersed in the floor surface, there is no protrusion on the floor surface, and when the hanging door is closed, the long groove rail piece makes the magnet of the guide rail piece Is projected and fitted into the long groove of the suspension door, so that the suspension door can travel reliably along the upper rail, and can perform the anti-swing action. Has the advantage that the protrusion is forcedly immersed in the outer cylinder and no protrusion is present on the floor surface.
