Description

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 hanging door, which can guide the hanging door securely without providing a guide rail or a grooved rail which always projects on the floor surface. ..

[0002]

2. Description of the Related Art A hanging door is suspended and supported by a rail fixed to an upper part through a hanger, and a lower end is a free end or is inserted into a grooved rail formed on a floor surface, and the hanging door is placed on an upper part. It is designed to be opened and closed by being guided by rails and groove rails.

[0003]

When the hanging door is hung and supported only by the upper rail, there is no protrusion or concave groove for supporting or guiding the lower portion of the hanging door on the floor surface. When it is opened, the floor surface is clean, but the lower part of the hanging door is not locked to the fixed side, so that the lower part of the hanging door swings in a direction orthogonal to the traveling direction. In addition, a rail may be laid on the floor surface to prevent the swinging of the hanging door, and an antivibration piece provided at the lower end of the hanging door may be locked to the rail. In this case, although there is an anti-sway effect of the hanging door, there is a risk that rail-shaped projections are present on the floor surface, impairing the aesthetics of the floor surface, and tripping over these projections during walking. In the case of using the grooved rail, the rail may be stumbled or dust may enter the groove to further impair the appearance of the floor surface.

According to the present invention, a protrusion such as a rail or a groove is not formed on the floor surface, moreover, when the hanging door is opened and closed, touch is prevented and the hanging door can be opened and closed surely at a predetermined position. With the goal.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, in which a hanging door is hung and supported by an upper rail via a hanger, and the hanging door is moved to the lower end of the hanging door. When the hanging door moves in the long groove formed in the direction, the guide embedded in the floor surface is inserted so that it protrudes and is inserted.The guide rail of the hanging door guides the hanging door at the lower end surface of the hanging door. A long groove is integrally formed in the moving direction, and an operation protrusion protruding below the inner top surface of one end of the long groove is provided, and this hanging door is hung on the upper rail and becomes flush with the floor surface in the moving direction. The guide rail is arranged in this way, and the guide rail at the position in the sliding door moving direction and the guide at the open position are provided with springs that always project to the floor surface. One guide is pivotally attached to an actuation link located in the guide rail. It has a retracting mechanism that retracts the suspension door immediately before moving through the link, and a differential cam that swings by the operation protrusion of the suspension door on the base end side of the operation link to move the operation link is inside the guide rail. Set up in.

Further, a guide push-up cam link fitted into the guide rail via a bracket is provided at the lower end of the hanging door,
The cam is moved along with the movement of the hanging door, and the guide rail or the self-weighting guide embedded in the floor is lifted up and down by this cam link.

[0007]

The guides are installed at predetermined intervals on guide rails buried in the floor in the direction in which the hanging door runs in the opening / closing direction, while the lower surface of the hanging door is set in the running direction. While forming a long groove into which the guide can be inserted,
When the hanging door is moved, the guide is projected through the link mechanism buried in the guide rail or is immersed in the floor surface. As a result, when opening and closing the hanging door that is hung from the upper rail only through the hanger, the guide projects above the floor just before the hanging door moves and the hanging door is positioned on the guide.
By being fitted in the long groove of the hanging door, the hanging door serves as a steady rest and is accurately guided. Then, when the hanging door stops above the guide, the guide holds the protruding state. Then, when the hanging door is moved to the open position, it is forcibly immersed in the guide rail via the link mechanism and becomes almost flush with the floor surface.When the door is opened, there are no protrusions on the floor surface, and it trips over. Dust will not accumulate in the groove, and the hanging door can be opened and closed smoothly.

[0008]

The present invention will be described below with reference to the illustrated embodiments. In the figure, R is a guide rail that hangs the hanging door D on the upper rail and guides it accurately. This guide rail is on the floor surface F along the moving direction of the hanging door and is flush with the floor surface. Fixed in place.

Finally, they are provided on the floor so that they are arranged in a line. Therefore, the top surface of the guide rail is substantially flush with the floor surface when the hanging door is open.

The guide rail R installed on the floor in the moving direction of the hanging door has a C-shaped section or a U-shaped section as shown in FIG.
It is composed of a rail-shaped rail body 1 and a lid piece 2 that covers the opening top surface of the rail body 1, and has a length to move from the fully closed position of the hanging door D to the fully open position shown in FIGS. 1 and 2. In addition, the lid piece 2 is required to have a hole for providing a guide that fits in a long groove formed in the lower end surface of the hanging door along the moving direction of the hanging door when the hanging door is fully opened and when the hanging door is fully opened. A plurality of holes are formed at intervals, and guides 10A and 10B shown in FIGS.
Provide inside. An operating link 11 is housed in the rail body 1 in its longitudinal direction, and the distal end (base end) of this operating link 11 is stored.
As shown in FIG. 3, it is pivotally attached to a part of the differential cam 12 through the shaft P1 and the operation link 11 is provided with guides shown in FIG.
0 is pivotally attached via a link 13, and the differential cam 12 swings so that all the guides 10A and 10B simultaneously project or retract from the guide rail top surface, that is, the floor surface via the operation link 11 and the link 13. Do like this.

Therefore, the differential cam 12 is swingably provided on the rail main body 1 by means of a shaft 14, and the top surface thereof is cut into a flat V-shape as shown in FIGS. The mountain surfaces 12a and 12b slightly project from the top surface of the rail body 1, and one of the mountain surfaces 12a and 12b is attached to the lower end surface of the hanging door D in the longitudinal direction as shown in FIG. 9 depending on the moving direction of the hanging door. In the formed long groove Da, the operation protrusion 1 protruding to the inner top surface
5 is made to swing over. A spring 16 is attached to the differential cam 12 so that the differential cam 12 automatically tilts to the left or the right when the dead point is passed.

Further, the differential cam 12 is disc-shaped as shown in FIG. 16, a part of the outer peripheral surface is cut out, and the differential cam 12 is swung by an operation projection 15 provided on the lower end surface of the hanging door in this cutout 12C. Thus, the disk-shaped differential cam 12 is pivotally attached to the rail main body 1 by the shaft 14, and one or more spring mechanisms 16A are provided. This spring mechanism 16A has an inner cylinder 16a.
The outer cylinder 16b and the outer cylinder 16b are telescopically fitted to each other.
A compression spring 16c is interposed between 6b so that both cylinders act in a repulsive direction by this spring pressure, and the outer cylinder 16b is attached to the differential cam 12 via a pin 16P, and the inner cylinder 16a.
Is locked to the rail main body 1 via a pin 16d, and the maximum compression point of this spring 16c is set as the dead point of the differential cam. The actuating cam 12 is swung so that the actuating link is swung. This action is the same as that of the embodiment shown in FIGS. 3 and 4, only the shapes of the differential cam and the spring are different.

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

The link 13 is L-shaped as shown in FIG. 10. A boss 13a is formed at the 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 piece is attached to the operation link, and the other end piece is attached to the guide.

As shown in FIGS. 8 and 11, the guide 10A is projected and retracted from the floor F by the action of the operating links 12 and 13, and is provided in the moving direction of the hanging door, and the guide 10B.

The bottom of the rail is locked to the rail body 1 with a screw 21, and the projecting guide piece 22 is inserted into and retractable from the outer cylinder, and when it is retracted, it is flush with the top surface of the guide rail. The outer diameter, the length, and the amount of projection are determined so that the slot is inserted into the long groove Da, and a long hole having a length corresponding to the amount of projection of the projecting guide piece is bored in the longitudinal direction of the outer peripheral surface of the outer cylinder 20. , The pin 23 protruding from the protruding guide piece is fitted and the pin 23 is fixed to the tip of the other end of the link 13 so that the operation of the link 13 guides the protruding guide piece 22 substantially. Do as you do.

In the guide 10B, a spring 24 is interposed between an outer cylinder 20 fixed to the rail body 1 with a screw and a protruding guide piece 22 fitted and inserted in the outer cylinder 20, and the spring pressure constantly moves the protruding guide piece 22 upward. The protrusion amount of the protrusion guide piece 22 is regulated by the pin 23 and the elongated hole, but the link 13 is not used.

Therefore, in the guide rail device for a hanging door constructed as described above, when the hanging door is fixed or fully opened along the wall P as shown in FIGS.
The protruding guide piece of the guide 10B is inserted in the lower end long groove Da of the hanging door. When the hanging door is moved in the closing direction, the operation cam of the hanging door kicks the differential cam, and the differential cam swings. Since the differential cam is connected to the actuating link and the actuating link via the link to the projecting guide piece 22 of each guide 10A, the projecting guide piece 22 of the guide 10A projects from the floor surface. When the hanging door D moves in this state, the guides of the guide rails are installed on the traveling locus of the hanging door, so the guide is naturally inserted into the long groove at the lower end of the hanging door and the hanging door travels. It prevents the touch in the direction perpendicular to the direction.

Further, when the hanging door is moved from the fully opened position to the fully closed position as shown in FIG. 1, the differential link is tilted to the opposite side by the operation protrusion of the hanging door, and through the operation link and the link,
The protruding guide piece 22 is set to be retracted into the guide rail on the floor, and the guide 10B is inserted into the long groove at the lower end of the hanging door at the fully opened position.

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

Further, in the third embodiment shown in FIG. 15, a bracket B is vertically installed at the lower end of the hanging 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.
Hang up. The bracket B has a length reaching 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 opened position to the fully closed position. As described above, the slits are formed on the top surface of the guide rail R over the moving range of the hanging door, specifically, the bracket.

The guide push-up cam link C is slidably inserted in the groove of the guide rail R as shown in the figure, and the tip top surface is tapered, whereby the hanging door D moves along the guide rail. At this time, the guide push-up cam link C moves together with the guides 10C and 10D provided on the floor by the tapered surface.
The lower end surface of the guide is 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 by their own weight.

Further, 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 adopted, and the guide 10A is provided in a closed position so that the guide 10A can be moved in and out in synchronization with the guide 10B via the link 30.

In the embodiment shown in FIG. 17, when the door is in an open state, that is, in the shed shown in FIGS. 1 and 2, the guide 10B shown in FIG. 7 is buried in the floor at the lower end of the door and always pushed up by a spring. The protruding guide piece 22 is inserted into the long groove Da provided at the lower end of the door, and the self-weight falling type guide 10A shown in FIG. 8 is embedded in the floor at the position where the door is closed, and between the both guides 10A and 10B. Is a rocking type link 30, and the ends of the link 30 are fixed by pins 23, 23, and the midpoint of the link 30 is adjustably pivoted to the rail body by a pin shaft. Both guides 10A and 10B contradict each other and are retracted from the floor by a link 30 that swings in a circular shape. At this time, the amount of protrusion of the guide 10A from the floor surface when the door is closed is performed by inserting pins by changing the positions of pin holes formed in the link 30. The guide groove Da provided at the lower end of the door has a tapered top surface 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 and waits for a moving door, and guide 10
When the position A is reached, the guide 10A is fitted in the guide groove of the door to stop the swing of the door.

In the embodiment shown in FIG. 18, two guides 10A and 10B are similarly embedded in the floor as shown in FIG. 17, and a link 30 fitted between the guides 10A and 10B in the rail main body. The guides 10A and 10B are connected to each other through an L-shaped link 13 so that the guides 10A and 10B operate in a reciprocal manner, and one end of the link 30 is pulled by a tension spring 31 so that the guide 10B projects when the door is open. If the guide 10B is pushed down by moving the door D, the other guide 10 is moved through the links 30 and 13.
A is made to project from the floor surface.

The embodiment shown in FIG. 19 is a modification of that shown in FIG. 18. The guide 10A is dropped and buried by its own weight, and when it is projected from the floor surface, the tip of the link 30 is an inclined surface 30a as shown in the drawing. When the link 30 moves, the pin 23 is pushed up by the inclined surface 30a so that the projecting guide piece 22 projects from the floor surface, and when the link 30 retracts, it is naturally buried by its own weight. The guide 10B is connected to the link 30 via the L-shaped link 13, and when the guide 10B is pushed down by the taper surface of the door and descends while swinging the link 13, the guide 10A projects through the link 30. Do as you do.

The embodiment shown in FIG. 20 is the same as the embodiment shown in FIG. 18 except that the two guides 10A, 10A are self-weighted, and both guides 10A,
The protruding and retracting operation of the protruding guide pieces 22, 22 of 10A is performed by attaching a magnet for attraction and a repulsion magnet to the top surface of the protruding guide piece 22 of the guide 10A arranged at the door open position and the inner top surface of the guide long groove Da, respectively. By embedding, the protruding guide piece 22 of the guide 10A in the open position is held in the projected or retracted state by utilizing the attraction / repulsion action of this magnet, and correspondingly, the guide 10A in the closed position (in FIG. 20, The left side) appears and disappears.

In the embodiment shown in FIG. 21, the guide at the closed position is a swing link type, and the center of this swing link 32 is pivotally attached to the rail main body by a pin shaft, and the tip of the link 30 and a pin. The guide 10B which is locked and in the open position is shown in FIGS.
In the same manner as the guide 10A, when the guide 10B is pushed down by the movement of the hanging door D, one piece of the swing link 32 projects from the floor via the links 30 and 13 like the guide 10A. It has an effect.

Further, in FIGS. 22 and 23, the guide 10B provided on the floor surface where the hanging door is opened and the protruding guide piece 22 of the guide 10B are depressed to swing the link 11 by the rack and the pinion. It is an example to be made.
In this embodiment, the rack 10L is engraved on one side surface of the protruding guide piece 22 of the guide 10B shown in FIG. 7, and the protruding guide piece 22 is provided in the box-shaped middle case 40 to be inserted into the rail body 1. A guide case 41, 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 axially supported by the middle case 41 is meshed with the rack 22L. A gear 43 having a lever 44 protruding from the gear 42 is meshed with the end of the lever 44 to be attached to the link 11 via a pin.

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

By adopting the rack and pinion lever type as described above, even if the pushing amount of the guide 10A is small, the protrusion amount on the guide 10B side can be set large by the gear ratio of the rack and pinion and the lever length, and the operation is reliable. There is an advantage that.

FIG. 24 shows another embodiment in which the guide 10B is replaced by a pin type and a fan gear type is used. In this embodiment, when the hanging door is in the open position, the other end of the fan-shaped lever 50 is swingably supported by the rail main body 1 via the pin so that the tip of the fan-shaped lever projects from the floor surface. The outer peripheral surface of the other end of 50 has an arc shape and teeth are engraved, and the fan-shaped gear 5
1 is engaged with the gear with lever 43 shown in FIG.
The tip of 4 is attached to the link 11. As a result, by moving the hanging door D, the fan-shaped lever slightly protruding from the floor surface is pushed down by the inclined surface of the long groove Da, and by pressing this fan-shaped lever, the fan-shaped gear 51 and the lever-equipped gear 43 are rotated, and the link 11
Is moved so that the guide 10A on the other side is projected from the floor surface.

The guide shown in FIGS. 25 and 26 is a guide 10A.
In the different embodiments, the tip of the guide retainer 53 under spring pressure is always pushed down by the spring pressure on the pin 23 projecting to the projecting guide piece 22, and the tip of the link 11 is an inclined surface, When moving by the pushing 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 lifts the protruding guide piece 22 from the floor surface against the spring pressure of the guide retainer. If the link 11 moves backward, the protruding guide piece 2
2 is pushed down by the spring pressure of the guide retainer 53 so that it is flush with the floor.

[0032]

According to the present invention, since the guide rail having the retractable guide is embedded in the floor and the long groove for inserting the guide is formed at the lower end of the hanging door, the floor is clean, When the hanging door is stored, make sure that the guide is fully retracted into the guide rail on the floor so that there is no protrusion on the floor surface.When closing the hanging door, the guide should be projected from the floor surface by moving the hanging door. Since it fits in the long groove, the hanging door can run reliably along the upper rail, and when the door is fully opened, the protrusion of this guide is forcibly submerged in the outer cylinder after passing through the hanging door. There are no protrusions on the floor surface, and there is an advantage that the protrusions on the floor surface are eliminated and the floor surface is refreshed.
