[0015]

Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, a suspension door 1 is suspended from an upper rail 2 provided at a high place by a plurality of runners 3 so as to be freely opened and closed. A plurality of guide pins 5 projecting into the lower end surface of the suspension door 1 from the upper surface of the lower rail 4.
Is provided with a traveling groove 6 through which the vehicle can pass. Its cross section is formed in a substantially U-shape, and the opening surface faces the floor.

A lower rail 4 is buried on the same floor as the floor below the floor 7 on the side of the passage just below the suspension door 1. The lower rail 4 has a substantially square cross section. Then, a guide roller 8 is fixed to the rear end of the upper surface, and the lower end surface of the suspension door 1 is inserted into the traveling groove 6 formed in a substantially U-shape. At substantially the center of the lower rail 4, a guide tunnel 9 having a substantially rectangular cross section is pierced through the passage parallel to the suspension door 1. Further, a substantially U-shaped storage groove 11 is buried under the floor of the storage side 10 of the hanging door 1. The storage groove 11 has a substantially unequal-sided L-shaped guide rod 12 having a substantially rectangular cross section. Then, a part of the end of the guide rod 12 having the approximately unequal side L-shape is slightly inserted into the guide tunnel 9 on the right to wait for the suspension door 1 to fully open.

The horizontal long side 13 of the guide rod 12 having a substantially unequal side L-shape is formed in a substantially rectangular cross section slightly smaller than the substantially rectangular cross section of the guide tunnel 9. The tip is slightly shorter than the front end of the lower part of the suspension door 1. And this vertical short side 1
4 is formed extremely shorter than the horizontal long side 13. The short vertical side 14 is fixed down from the rear end of the substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1. Further, a substantially semicircular concave guide groove 15 is provided symmetrically on the left and right sides of the vertical long side 13 of the substantially unequal-side L-shaped guide rod 12. The guide groove 15 having a substantially semicircular concave shape is formed such that when the tip of the guide rod 12 having a substantially inequilateral L-shape is low and reaches a predetermined height with a gentle inclination toward the rear end, the guide rod 12 is turned horizontally to make a vertical short. It is provided continuously to the vicinity of the side 14.

A guide tunnel 9 penetrating the lower rail 4
Then, a plurality of cylindrical guide pin holes 16 are formed through the upper surface of the lower rail 4. Then, a substantially cylindrical guide pin 5 provided with a mechanism part capable of engaging with a substantially unequal-sided L-shaped guide rod 12 is fitted therein so as to be vertically movable.

Referring to FIG. 2, a substantially cylindrical guide pin 5 provided with a mechanism portion engageable with a substantially unequal-sided L-shaped guide rod 12 will be described in detail. A guide tunnel 9 having a substantially rectangular cross section and extending substantially at the center of the lower rail 4 has a plurality of guide pin holes 16 extending through the upper surface of the lower rail 4. The guide pin 5 formed in a substantially cylindrical shape has a roller 17 rotatably provided on the head thereof. Further, a substantially frog crotch-like passage 18 is formed from the middle to the lower end thereof, and is fitted into the guide pin hole 16 on the right so as to be able to move up and down.

This substantially frog crotch-like shape is a passage that is slightly larger than the substantially rectangular cross section of the horizontal long side 13 of the substantially unequal-L-shaped guide rod 12 and is opened to the left and right. Accordingly, the guide rod 12 having a substantially inequilateral L-shape having a substantially rectangular cross section is
The substantially frog-grooved passage 18 can be inserted. And
A guide ball 19 is buried on the left and right of the inner wall of the substantially frog crotch-shaped passage 18 so as to face each other. However, this guide ball 19
One half or more of them are buried, but they are rotatable. The guide ball 19 is formed to be slightly smaller than the diameter of the substantially semicircular concave guide groove 15 provided symmetrically on the left and right sides in the vertical plane of the horizontal long side 13 of the substantially unequal-sided L-shaped guide rod 12. Therefore, when the substantially cylindrical guide pin 5 is at the lower end of the guide pin hole 16, the protruding portion of the guide ball 19 buried opposite to the left and right inner walls of the substantially frog-grooved passage 18 and the substantially unequal L-shape The guide rod 12 has a substantially semicircular concave guide groove 15 provided on the left and right sides of the vertical plane of the horizontal long side 13 of the guide rod 12.

A substantially frog-grooved passage 1 formed in a guide pin 5
8, hemispherical recesses 20 are provided on the left and right sides in the horizontal direction passing through the center of the guide pin 5 in the 90-degree direction. And
A semi-circular groove 21 somewhat shallower than that is provided continuously from the semispherical recess 20 on the right to the lower end surface of the guide pin 5. Further, at the lower end of the guide pin 5, small holes 22 are provided on the left and right of the wall surface of the guide pin hole 16 that matches the hemispherical recess 20, and a cylindrical stopper chamber 23 slightly larger than the diameter of the small hole 22 is provided horizontally. .

In the stopper chamber 23, a lock ball 24 having substantially the same size as the diameter of the hemispherical recess 20 described above is provided.
A spring 25 for pressing the lock ball 24 is incorporated. The small hole 22 on the right is the lock ball 2
Since the lock ball 24 is formed slightly smaller than the four diameters, the lock ball 24 does not protrude into the guide pin hole 16. Therefore, at the lower end of the guide pin 5, the lock ball 24 pressed against the spring 25 enters the hemispherical recess 20, and holds the position without being raised by vibration or the like.

From the middle to the lower end of the guide pin 5, a substantially frog crotch-like passage 18 opens to the left and right, and the cross section of the leg 26 has a half-moon shape. The bottom of the guide pin hole 16 forms a half-moon-shaped depression 27 in which the half-moon-shaped leg 26 is fitted.
However, they are formed at a slightly lower position across the bottom surface of the guide tunnel 9 from side to side. Therefore, the guide pin 5 does not rotate at the lower end.

A ring groove 28 is provided on the lower rail 4 above the guide pin hole 16. The packing 29 is attached here so that dust and rainwater do not enter.

The opening and closing operation of the hanging door 1 will be described with reference to FIGS. In FIG. 1, a hanging door 1 suspended by a plurality of runners 3 on an upper rail 2 provided at a high place.
Although not shown, it can be automatically opened and closed by an external drive device. After the hanging door 1 is opened and stands by at the storage side 10, when the external drive device confirms that there is no pedestrian or the like on the passage side 7, the external driving device starts operating the hanging door 1 in the closing direction. A guide roller 8 fixed to the rear end of the upper surface of the lower rail 4 so as to be rotatable by a shaft always enters a substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1. When the suspension door 1 moves in the closing direction, the substantially unequal-sided L-shaped guide rod 12 fixedly suspended from the rear end of the lower end surface of the suspension door 1 also advances in the guide tunnel 9.

FIG. 2 is a partial perspective view taken along the line AA of FIG. When the distal end of the substantially unequal-sided L-shaped guide rod 12 is gradually inserted into the substantially frog-grooved passage 18 of the guide pin 5, it is rotatably embedded in the left and right inner walls of the substantially frog-grooved passage 18 of the guide pin 5. The guide ball 19 slides into the substantially semicircular concave guide groove 15 provided symmetrically on the left and right in a vertical plane of the guide rod 12 having a substantially unequal side L-shape. In this manner, when the closing operation of the suspension door 1 further proceeds, the guide rod 12 having a substantially unequal L-shape further advances in the guide tunnel 9. Since the substantially semicircular concave guide groove 15 provided symmetrically on the vertical plane left and right of the substantially unequal-side L-shaped guide rod 12 rises with a gentle inclination, the guide pin 5 necessarily rises. A plurality of guide pins 5 that gradually project from the upper surface of the lower rail 4
Sequentially enter the substantially U-shaped running groove 6 formed in the lower end surface of the sliding door 1 to guide the hanging door 1.

FIG. 3A is a sectional view taken along the line BB of FIG. The substantially semicircular concave guide groove 15 provided symmetrically on the vertical plane left and right of the substantially inequilateral L-shaped guide rod 12 changes its direction horizontally when it reaches a predetermined height and is continuous. 5 holds the highest position. The heads of the plurality of guide pins 5 protruding from the upper surface of the lower rail 4 enter a substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1 to guide the suspension door 1. The lock ball 24 built in the stopper chamber 23 has a hemispherical recess 2.
Escape from 0 and roll in a shallow semicircular groove 21 that continues from this hemispherical recess 20

In FIG. 1, although not shown, the suspension door 1 is controlled to stop slowly by an external drive device immediately before it collides with a pillar 30 in front of the suspension door 1 and is fully closed. The heads of the plurality of guide pins 5 protruding from the upper surface of the lower rail 4 enter a substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1 to hold the suspension door 1 closed.

FIG. 3B is a sectional view taken along the line CC of FIG. The substantially unequal-sided L-shaped guide rod 12 is fixedly suspended from the rear end of the substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1. The horizontal long side 13 is inserted into the guide tunnel 9 having a substantially rectangular cross section. A substantially U-shaped storage groove 11 is formed below the floor of the storage side 10 of the suspension door 1 so that the guide rod 12 having a substantially unequal L-shape can pass freely. Further, the two end sides 31 on the floor are vertically folded to prevent foreign matter from entering the inside.

In FIG. 2, when the closed hanging door 1 is opened by an external driving device, the hanging door 1 starts to retreat. Then, the reverse operation is performed this time, and the substantially unequal side L
The letter-shaped guide bar 12 retreats. The guide pin 5 gradually descends from the highest position in accordance with the gentle inclination of the substantially semicircular concave guide groove 15 formed symmetrically in the left-right direction on the vertical plane of the substantially inequilateral L-shaped guide rod 12. The heads of the plurality of guide pins 5 are sequentially extracted from the substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1 and are flush with the upper surface of the lower rail 4. There are no obstacles, and there is no obstacle to traffic.

During the opening operation of the suspension door 1, the guide pin 5 may not descend due to some trouble. In this case, it is conceivable that the head portion of the guide pin 5 that is projected on the upper surface of the lower rail 4 damages the front end of the substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1. Therefore, a flip-up door 32 that opens only to the outside is provided at the front end of the substantially U-shaped traveling groove 6 formed on the lower end surface of the suspension door 1. The flip-up door 32 is a guide pin 5 that cannot be lowered while the hanging door 1 is in the open operation.
When the head collides with the head, the impact spring jumps outward and opens, so that the suspension door 1 and the guide pin 5 head are not damaged. The flip-up door 32, which has jumped outward,
When the attached arm 33 separates from the limit switch 34, the limit switch 34 outputs an abnormal signal. The external drive device can detect this and perform an emergency stop.

FIG. 4 is a partial fragmentary view of the lower rail 4 and the substantially unequal L-shaped guide bar 12. In this embodiment, the substantially cylindrical guide pins 5 are replaced by a substantially long cylindrical guide pin 35 and a substantially square pillar guide pin 37, respectively. These form a substantially frog crotch-like passage 18 from the middle to the lower end thereof similarly to the substantially cylindrical guide pin 5.

Referring to FIG. 5, another embodiment for moving the guide pin up and down will be described. An L-shaped guide rod 12 having a substantially unequal side that is inserted through the guide tunnel 9 of the lower rail 4
Has a substantially rectangular cross section. The front end of the upper flat surface of the horizontal long side 13 is low, and when reaching a predetermined height with a gentle inclination toward the rear end, the direction is changed more horizontally. Further, a guide pin 39 with a ball provided with a mechanism capable of sliding or rotating on an upper plane of a substantially inequilateral L-shaped guide rod 12 having a substantially rectangular cross section is attached to the guide tunnel 9 of the lower rail 4. Into the guide pin hole 40 penetrated from the upper surface to the upper surface.

The guide pin hole 40 on the right is formed in a substantially cylindrical shape, but a ring groove 28 is provided in the upper part on the lower rail 4 side, a packing 29 is mounted therein, and a convex half ring 41 is formed in the lower part. Are provided on the left and right. The guide pin 39 with a ball fitted into the guide pin hole 40 so as to be able to move up and down is formed in a substantially columnar shape, and a flange 42 is provided at a lower portion thereof. The lifting ball 43 is buried at the lowermost end thereof, and can be freely rotated without dropping. The guide pin 39 with a ball is pressed downward because the flange 44 receives the spring 44 provided in the guide pin hole 40. Thus, the convex semi-ring 41 in the guide pin hole 40 collides with the flange 42 on the right, and the head of the ball-mounted guide pin 39 stands by on the same surface as the upper surface of the lower rail 4.

The hanging door 1 waiting on the storage side 10 starts operating in the closing direction by controlling the closing operation of the external drive device. A guide roller 8 fixed to the rear end of the lower rail 4 so as to be rotatable by a shaft enters a substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1 and guides the suspension door 1 accurately.

When an approximately unequal L-shaped guide rod 12 is inserted forward into the guide tunnel 9, an upper flat surface at the tip thereof is lifted and lowered by a lifting ball 43 rotatably embedded at the lowermost end of a guide pin 39 with a ball. And comes into contact with the lifting ball 43. The guide rod 12 having a substantially unequal side L-shape
The tip is low and has a gentle slope toward the rear end. Therefore, the lifting ball 43 is gradually pushed up. Then, the head of the guide pin 39 with the ball projects from the upper surface of the lower rail 4, enters the substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1, and guides the suspension door 1. Further, when the guide rod 12 having an approximately unequal side L-shape is inserted in front of the guide tunnel 9, the upper plane thereof reaches a predetermined height and is formed horizontally to the vertical end 13. 43 is a guide rod 1 having an approximately unequal L-shape.
Rolling on the upper flat surface of the second horizontal long side 13, the plurality of guide pins 39 with balls are held at the highest position to guide the hanging door 1.

Referring to FIG. 6, there will be described an embodiment in which the guide rod 12 having a substantially unequal side L-shape can be synchronously interlocked even if the guide rod 12 is cut off from the hanging door 1. A fixed magnet 45 is fixed to the rear end portion of the substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1 close to the floor. A storage rail 46, which is formed below the floor of the storage side 10 of the suspension door 1 in a substantially rectangular cylindrical shape, is embedded. A traveling rail 47 having an uneven shape is formed on the left and right sides, and a bogie 48 is erected on the traveling rail 47 so as to run freely. The cart 48 is provided with axles 49 on all sides and rotatably supports wheels 50. Further, the traveling magnet 51 is mounted on the carriage 48 with the surface on which the magnetic force is attracted and the fixed magnet 45 on the right facing each other. Further, the vertical end 13 of the guide rod 12 having a substantially unequal side L-shape is fixed down from the carriage 48.

The bogie 48 is provided in the storage rail 46 formed in a substantially square cylindrical shape in synchronization with the suspension door 1 by the magnetic attraction of the fixed magnet 45 and the traveling magnet 51 as the suspension door 1 is opened and closed. It travels on the traveling rail 47. Therefore, as described above, the horizontal movement of the substantially inequilateral L-shaped guide rod 12 passing through the guide tunnel 9 is controlled by the guide pin 5.
, And the head of the guide pin 5 sequentially projects from the upper surface of the lower rail 4, enters the substantially U-shaped running groove 6 formed on the lower end surface of the suspension door 1, and guides the suspension door 1.

Referring to FIG. 7, another embodiment different from the above will be described. A storage rail 46, which is formed below the floor of the storage side 10 of the suspension door 1 in a substantially rectangular cylindrical shape, is embedded. A traveling rail 47 having an uneven shape is formed on the left and right sides, and a bogie 48 is erected on the traveling rail 47 so as to run freely. The vertical end 13 of the guide rod 12 having a substantially unequal side L shape is fixed down from the carriage 48. A fixed linear motor 52 is fixedly mounted on the upper surface of the storage rail 46 on the right with the length of the storage rail 46.
3 is installed.

Although not shown, it is controlled in conjunction with the opening / closing control section of the external driving device, and the pair of linear motors 52, 5
By controlling 3, the truck 48 on the right can be freely passed through the storage rail 46 formed in a substantially rectangular cylindrical shape in synchronization with opening and closing of the suspension door 1. Therefore, the horizontal movement of the substantially inequilateral L-shaped guide rod 12 inserted in the guide tunnel 9 is converted into the vertical movement of the guide pin 5, and the heads of the plurality of guide pins 5 sequentially protrude from the upper surface of the lower rail 4. A substantially U-shaped running groove 6 formed in the lower end surface of the suspension door 1
And guides the hanging door 1.

Although not shown, the present invention can be applied to a hanging door that opens and closes left and right and a curved hanging door.

[0042]

The present invention has the following effects by being configured as described above. Pedestrians do not have to worry about walking because there are no bumps on the aisle floor. However, in a suspended door floor structure seen in a city, a concave groove or a convex groove crosses the passage as a guide of the suspended door. This structure is not good in appearance, such as accumulation of dust and rainwater, and also causes malfunction. The uneven groove is one of the major obstacles for people using wheelchairs.

In the present invention, a guide roller is fixed on the upper surface of the rear end of the lower rail, and is inserted into a substantially U-shaped running groove formed on the lower end surface of the suspension door. Therefore, the lower end surface of the suspension door is always guided, and the opening and closing operation is stabilized. Then, a plurality of guide pin heads are sequentially projected into the upper surface of the lower rail to guide and hold the lower end surface of the suspension door, but a driving device is not particularly required. That is, the operating force for opening and closing the hanging door is applied.

In the embodiment in which the underfloor on the side where the hanging door is stored is formed in a substantially rectangular cylindrical shape, the guide rod having a substantially unequal L-shape is indirectly driven by a magnet or a linear motor. Therefore, the hanging door has a structure that is cut off. Therefore, except for the fixed guide roller, the structure above the floor of the hanging door has no irregularities and forms a flat upper surface. Further, since there is no intrusion of dust or rainwater, malfunctions caused by these do not occur.

Further, since the guide pin head is not made of a fragile substance such as a magnet, it is not broken by the umbrella of a pedestrian. In the means using a magnet for the guide pin head, there is a danger that the head may be kept in a state where the head protrudes from the upper surface of the floor and collides with the lower end surface of the hanging door by using a fine magnetic material magnetized on the magnet. Further, in the case where a plurality of electromagnetic magnets are provided under the floor immediately below the suspension door and the central iron core is used as a guide pin, electricity flowing through the electromagnetic magnets due to rainwater or the like may leak, causing an electric shock accident.

The guide pin according to the present invention comprises a substantially semicircular concave guide groove provided symmetrically on the vertical plane left and right of a substantially inequilateral L-shaped guide rod, and a substantially frog crotch-like shape provided from the middle to the lower end of the guide pin. A guide ball embedded in the inner wall of the passage engages with each other and is connected or released. The operation is ensured by a mechanism that converts the horizontal movement of the substantially inequilateral L-shaped guide rod into the vertical movement of the guide pin.
In the means for indirectly driving the substantially unequal-sided L-shaped guide rod with a magnet, if the main part of the suspension door is made of a non-magnetic metal, one of the magnets can be made of a magnetic metal to achieve the purpose. Is possible. Moreover, the guide pin of the present invention can create a harmonious landscape by using the same material as the lower rail or the same material as the floor material.
