DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail device for a suspension door which can reliably guide the suspension door without providing a guide rail which always projects on the floor or a groove-shaped rail. .

[0002]

2. Description of the Related Art A hanging door is suspended and supported via a hanger by a rail fixed to an upper part, and a lower end is a free end or is inserted into a groove rail formed on a floor surface. It is guided by rails and groove rails to open and close.

[0003]

When the suspension door is suspended and supported only by the upper rail, there is no protrusion or a groove on the floor surface for supporting or guiding the lower part of the suspension door. When opened, the floor is clean, but on the other hand, there is a drawback that the lower part of the hanging door swings in a direction perpendicular to the running direction because nothing is locked on the lower side of the hanging door. Further, a rail may be laid on the floor surface to prevent the swing of the hanging door, and a vibration stopper provided at a lower end of the hanging door may be locked to the rail. In this case, the suspension door has an anti-sway effect, but there is a rail-shaped projection on the floor surface, and there is a risk that the aesthetic appearance of the floor surface may be impaired or the projection may trip over when walking. In the case of a grooved rail, the rail may trip over the groove, or dust may enter the groove, further degrading the appearance of the floor surface.

According to the present invention, it is possible to prevent a contact when opening and closing a suspension door and to surely open and close the suspension door at a predetermined position without forming a projection such as a rail or a concave groove on a floor surface. With the goal.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments.

In the figure, R is a guide rail which suspends the hanging door D from the upper rail and guides it accurately. This guide rail is on the floor F along the moving direction of the hanging door, and is flush with the floor. It is buried and fixed so that For example, as shown in FIG. 1 and FIG. 2, when the hanging door D is fully opened along the fixed door or the wall P, one or more hanging doors are sent out one by one from a state of being overlapped with each other, Finally, they are provided on the floor so as to be arranged in a line. Therefore, the top surface of the guide rail is substantially flush with the floor surface when the hanging door is opened.

As shown in FIG. 5, a guide rail R installed on the floor in the direction of movement of the hanging door has a C-shaped cross section or a U-shaped section.
A rail main body 1 having a letter shape and a cover piece 2 for covering the opening top surface of the rail main body 1 have a length that moves from the fully closed position of the suspension door D to the fully open position shown in FIGS. In addition, the lid piece 2 is required to have a hole for allowing the guide to fit in a long groove formed along the moving direction of the hanging door on the lower end surface of the hanging door when the hanging door is fully opened and when the hanging door is fully opened. A plurality of holes are drilled at intervals, and guides 10A and 10B shown in FIGS.
Provided within. An operating link 11 is accommodated in the rail body 1 in a longitudinal direction thereof, and a distal end (a base end) of the operating link 11 is housed.
As shown in FIG. 3, the operation link 11 is pivotally connected to a part of the differential cam 12 via the shaft P1.
0, and all the guides 10A and 10B simultaneously project or retract from the top surface of the guide rail, that is, the floor surface, through the operation link 11 and the link 13 by the swing of the differential cam 12. I will do it.

Accordingly, the differential cam 12 is swingably provided on the rail main body 1 by the shaft 14, and the top surface is cut into a flat V-shaped top surface as shown in FIGS. The mountain surfaces 12a, 12b slightly protrude from the top surface of the rail main body 1, and either one of the mountain surfaces 12a, 12b is moved in the longitudinal direction at the lower end surface of the hanging door D as shown in FIG. Operation projection 1 protruding from the inner top surface inside the formed long groove Da
At 5, the swinging operation is performed. The differential cam 12 is provided with a spring 16 so as to automatically tilt to either the left or the right after passing the dead point.

Further, the differential cam 12 is formed in a disk shape as shown in FIG. 16, and a part of an outer peripheral surface thereof is cut out, and swings by an operation projection 15 projecting from the notch 12C on the lower end surface of the suspension door. Thus, the disc-shaped differential cam 12 is provided with one or more spring mechanisms 16A. This spring mechanism 16A has an inner cylinder 16a.
And the outer cylinder 16b are fitted in a telescopic manner.
A compression spring 16c is interposed between the inner cylinder 16b and the outer cylinder 16b is engaged with the differential cam 12 via a pin 16P.
Is locked to the rail body 1 via a pin 16d, and the maximum compression point of the spring 16c is used as a dead point of the differential cam. , The operating cam 12 swings to swing the operating link. This operation is the same as that of the embodiment shown in FIGS. 3 and 4, except that the shapes of the differential cam and the spring are different.

In the embodiment shown in FIG. 16, when the door is closed, only one guide 10A supporting the lower end of the door shown in FIG. 8 is used for one door. Is the same as the embodiment shown in FIGS.

The link 13 is L-shaped as shown in FIG. 10. A boss 13a is formed at a central bent portion, a shaft is inserted through the boss, and the link 13 is pivotally attached to the rail body so as to be swingable.
One end is engaged with the operating link, and the other end is engaged with the guide.

As shown in FIGS. 8 and 11, the guide 10A is protruded and retracted from the floor F by the action of the operation link 12 and the link 13, and is provided in the moving direction of the suspension door.
Has a shape as shown in FIGS. 7 and 12, and is installed at the open position of the hanging door. The guide 10A has an outer cylinder 20 whose outer diameter and shape are determined so as to be fitted into holes of the lid 2 of the rail body 1.
The bottom of the rail is locked to the rail body 1 with a screw 21, and the protruding guide piece 22 is inserted and retractably inserted into the outer cylinder. The outer diameter, the length, and the amount of protrusion are determined so as to be inserted into the long groove Da, and a long hole having a length corresponding to the amount of protrusion of the protrusion guide piece is formed in the longitudinal direction of the outer peripheral surface of the outer cylinder 20. Then, a pin 23 projecting from the projecting guide piece is fitted and inserted, and this pin 23 is engaged with the tip of the other end of the link 13 so that the guide is activated by the operation of the link 13, and the projecting guide piece 22 substantially emerges. I will do it.

In the guide 10B, a spring 24 is interposed between the outer cylinder 20 screwed to the rail body 1 and the protruding guide piece 22 fitted therein, and the protruding guide piece 22 is always moved upward by the spring pressure. And the amount of protrusion of the protruding guide piece 22 is restricted by the pin 23 and the elongated hole, but the link 13 is not used.

Therefore, in the guide rail device for a suspension door constructed as described above, when the suspension door is fixed or fully opened along the wall P as shown in FIGS.
A protruding guide piece of the guide 10B is inserted into the lower end long groove Da of the suspension door. When the hanging door is moved in the closing direction, the differential cam is kicked by the operation projection of the hanging door, and the differential cam swings. Since the differential cam is connected to the operation link and the operation link to the projecting guide piece 22 of each guide 10A via the link, the projecting guide piece 22 of the guide 10A protrudes from the floor surface. When the suspension door D moves in this state, the guide of the guide rail is installed on the traveling locus of the suspension door, so that the guide is naturally inserted into the long groove of the lower end of the suspension door, and the travel of the suspension door is performed. This prevents touch in the direction perpendicular to the direction.

When the suspension door is moved from the fully open position to the fully closed position as shown in FIG. 1, the differential link is tilted to the opposite side by the operation projection of the suspension door, and the operation link and the link are used.
The protruding guide piece 22 is immersed in the guide rail on the floor surface, and the guide 10B is inserted into the long groove at the lower end of the suspension door at the fully open position.

FIG. 14 shows an embodiment in which the guide is electrically protruded and retracted, and the upper rail is used to detect a fully closed position A of the hanging door and a movement for detecting the movement of the hanging door from the fully opened position to the fully opened door. A sensor or a switch is provided at each detection position B, and the sensor or switch at each of the positions A and B is detected at the position of the hanging door. A guide rail R buried on the floor surface has a guide 10B and a solenoid valve. SV
1, SV2, and the solenoid valve SV1 or SV
2 is operated, and the guides 10C and 10D provided on the solenoid valves SV1 and SV2 are protruded and retracted from the guide rail surface of the floor surface to perform the same operation as in the first embodiment.

In the third embodiment shown in FIG. 15, a bracket B is vertically provided at the lower end of the suspension door D and at one end thereof, and a guide push-up cam link C is provided at the lower end of the bracket B.
Mooring. The bracket B has a length that reaches the inner groove of the guide rail R provided on the floor surface, and is movable together with the bracket B and the hanging door when the hanging door D moves from the fully open position to the fully closed position. In this way, the top surface of the guide rail R is formed with a slit over the moving range of the suspension door, specifically, the bracket.

The guide push-up cam link C is slidably fitted into the groove of the guide rail R as shown in the figure, and has a tapered top end so that the hanging door D moves along the guide rail. At this time, the guides 10C and 10D which move together with the guide lifting cam link C and are provided on the floor surface with a tapered surface.
The lower end surface of the cam link C is made to be pushed up, and the pushed lower end surface of the guide is supported by the top surface of the cam link C. The guides 10C and 10D naturally descend under their own weight.

In the embodiment shown in FIG. 17 and subsequent figures, when the door is closed, one door is supported by one guide 10A, and this guide 10A is lowered by its own weight as shown in FIG. The guide 10A is provided at a position where the door is closed, and the guide 10B is moved up and down synchronously via the link 30 by the ascending and descending operation of the guide 10B.

In the embodiment shown in FIG. 17, when the door is open, that is, when the door is in the state shown in FIGS. 1 and 2, a guide 10B shown in FIG. 7 is buried in the floor at the lower end of the door, and is always pushed up by a spring. The protruding guide piece 22 to be inserted is inserted into a long groove Da provided at the lower end of the door, and a guide 10A of a self-weight drop type shown in FIG. 8 is buried on the floor where the door is closed, and between the guides 10A and 10B. Is provided with an oscillating link 30, and the ends of the link 30 are engaged via pins 23, 23, and the midpoint of the link 30 is adjustably pivotally attached to the rail body with a pin shaft. The two guides 10A and 10B are contradictoryly protruded and retracted from the floor surface by the link 30 which swings in the shape of a circle. At this time, the amount of protrusion of the guide 10A from the floor surface at the time of closing the door is changed by changing the position of a plurality of pin holes formed in the link 30 and inserting pins. The guide groove Da provided at the lower end of the door has a top surface tapered on one end side of the door, and when the top surface of the protruding guide piece 22 of the guide 10B is pushed down by the tapered surface Db, the other guide is provided via the link 30. 10A protrudes, waits for the moving door, and guides 10
When reaching the position A, the guide 10A is fitted into the guide groove of the door to stop the swing of the door.

In the embodiment shown in FIG. 18, as shown in FIG. 17, two guides 10A and 10B are similarly buried in the floor, and a link 30 fitted between the two guides 10A and 10B in the rail body is provided. The link 10 is connected via an L-shaped link 13. The link 13 is provided so that the guides 10A and 10B operate reciprocally. One end of the link 30 is pulled by a tension spring 31, and the guide 10B at the time of opening the door is protruded. Is buried, and if the guide 10B is pushed down by the movement of the door D, the other guide 10
A projects from the floor surface.

The embodiment shown in FIG. 19 is a modification of the one shown in FIG. 18. The guide 10A is dropped and buried under its own weight, and when projecting from the floor, the tip of the link 30 is formed as an inclined surface 30a as shown in FIG. When the link 30 moves, the pin 23 is pushed up by the inclined surface 30a so that the protruding guide piece 22 protrudes from the floor surface, so that the link 30 is naturally buried under its own weight when retreating. The guide 10B is connected to the link 30 via the L-shaped link 13. When the guide 10B is pushed down by the tapered surface of the door and descends while swinging the link 13, the guide 10A protrudes through the link 30. I will do it.

The embodiment shown in FIG. 20 is the same as the embodiment shown in FIG. 18 except that the two guides 10A, 10A are both self-weighted, and both guides 10A, 10A are identical.
The projecting guide pieces 22, 22 of the 10A projecting and retracting operation are performed by attaching magnets for attracting and repelling to the top surface of the projecting guide piece 22 of the guide 10A and the inner top surface of the guide long groove Da, respectively. It is buried, and the protruding guide piece 22 of the guide 10A in the open position is held in a protruding state or a sunk state by utilizing the attracting / repelling action of the magnet, and the guide 10A in the closed position (FIG. Left side).

In the embodiment shown in FIG. 21, the guide at the closed position is a swinging link type, and the center of the swinging link 32 is pivotally connected to the rail body with a pin axis, and the tip of the link 30 and a pin are used. The guide 10B in the engaged and open position is shown in FIGS.
When the guide 10B is pushed down by the movement of the suspension door D, one piece of the swing link 32 projects from the floor surface via the links 30 and 13 so that the same as that of the guide 10A. It has an effect.

22 and 23, the link 11 is swung by a rack and a pinion by pressing a guide 10B provided on the floor surface where the hanging door is open and a protruding guide piece 22 of the guide 10B. This is an example of the operation.
In this embodiment, a rack 10L is engraved on one side surface of the protruding guide piece 22 of the guide 10B shown in FIG. 7, and this protruding guide piece 22 is provided in a box-shaped middle case 40 that is inserted into the rail body 1. A spring is interposed between the bottom surface of the protruding guide piece 22 and the inner bottom surface of the rail body, and a pinion gear 42 supported by the middle case 41 is meshed with the rack 22L. A gear 43 having a lever 44 projecting therefrom is engaged with the gear 42, and the tip of the lever 44 is engaged with the link 11 via a pin.

Both the pinion gear 42 and the gear 43 are rotatably supported by a middle case 40 via a shaft, and when the hanging door D moves, the projecting guide piece 2 is formed on the inclined surface of the inner top surface of the long groove Da.
2 is pushed down, the rack 22 of the guide piece 22
The pinion gear 42 meshed with L rotates, whereby the gear 43 also rotates. Since the lever 44 projects from the gear 43, the lever 44 swings around the axis of the gear 43, thereby moving the link 11 fixed to the tip of the lever. Since the guide 10A at the distal end of the link 11 and the closed position is the same as that of the embodiment of FIG. 19, the guide 10A protrudes from the floor surface.

As described above, by using the rack and pinion lever type, even if the guide 10A is pressed down a little, the protruding amount of the guide 10B side can be set large by the ratio of the number of teeth of the rack and pinion and the lever length, and the operation is reliable. There are advantages.

FIG. 24 shows a different embodiment in which the guide 10B is replaced by a pin type and a sector gear type. In this embodiment, when the hanging door is at the open position, the other end is swingably supported on the rail main body 1 via a pin so as to protrude from the floor surface via a pin. The outer peripheral surface of the other end of the circular gear 50 is formed in an arc shape, and teeth are carved.
1 meshes with a gear 43 with lever shown in FIG.
4 is engaged with the link 11. Thus, the fan-shaped lever slightly projecting from the floor surface is pushed down on the inclined surface of the long groove Da by the movement of the suspension door D, and the fan-shaped gear 51 and the gear 43 with the lever are rotated by pressing the fan-shaped lever, and the link 11
Is moved so that the guide 10A on the other side protrudes from the floor surface.

FIGS. 25 and 26 show the guide 10A.
In a different embodiment of the present invention, the tip of the guide presser 53 under spring pressure is configured to always push down the pin 23 projecting from the projecting guide piece 22 by this spring pressure, and the tip of the link 11 is formed as an inclined surface. When the link 10 is moved by the pressing force of the guide 10B, the inclined surface of the tip of the link 11 enters below the pin 23, pushes up the pin 23, and raises the protruding guide piece 22 from the floor surface against the spring pressure of the guide presser. When the link 11 retreats, the projecting guide piece 2
2 is pushed down by the spring pressure of the guide presser 53 so as to be flush with the floor surface.

[0032]

According to the present invention, a guide rail provided with a retractable guide is embedded in the floor and a long groove is formed at the lower end of the suspension door to insert the guide, so that the floor is clean. When you put the hanging door, make sure that the guide is immersed in the guide rail on the floor surface and there is no protrusion on the floor surface, and when closing the hanging door, the guide moves out of the floor by moving the hanging door. Since it is inserted into the long groove, the suspension door can travel reliably along the upper rail, and when fully opened, after passing through the suspension door, the protrusion of this guide is forced to sink into the outer cylinder, There is no protrusion on the floor surface, and there is an advantage that the floor surface has no protrusion and is clean.
