Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side-sliding door that is installed at an entrance for vehicles at a construction site or at an entrance to a building such as a warehouse along the coast.

Conventional doors of this type have a high gate structure at construction sites so as not to impede the entry and exit of vehicles.
A suspension gate structure in which the suspension girder is higher than the vehicle is generally adopted, but with this structure the door is inevitably large, requiring a great deal of effort to open and close. In order to withstand wind, etc., it must be constructed on a large scale.

On the other hand, as shown in Figures 11 to 13, relatively low doors (a) are used for tide doors installed at the entrances and exits of warehouses along the coast.
Since using a hanging girder as a hanging gate would impede the entry and exit of vehicles, etc., a structure in which the gate runs on rails b laid on the ground is adopted.

However, with such a structure, sand and debris accumulate on the rails B, making it difficult to run, and when submerged in seawater, the wheels C rust and become unable to rotate smoothly. There is a risk that it may fall down due to lateral vibration caused by vibrations over time.

In addition, when used as a flood protection door, the door a must be placed in close contact with the entrance d of the building to ensure watertightness, but in order to move the door a toward the entrance, it must be moved laterally on the rail b with the wheels c. In addition, to tighten the door a towards the entrance/exit side, the handle e provided on the inside of the door a must be rotated to rotate the hook f, and a large amount of force is required to tighten it. This method employs means for engaging with a locking groove g provided on the inner circumferential surface, and has drawbacks such as the difficulty of providing external tightening means, which is the easiest to operate.

In order to eliminate such drawbacks, the present invention provides a movable rail on one side of the doorway toward the other side of the doorway, and a door is movably suspended from this rail. The door is characterized by a structure in which only the rail is moved in the length direction toward the entrance and is hung horizontally at the entrance, and then the door is suspended from the rail and moved along the rail toward the entrance. This provides a horizontally sliding door.

Make 0 slightly raised. Then,
Grip the handle 21 and pull the moving rail 10 toward the entrance/exit 1 side. At this time, there is a door 1 on the moving rail 10.
Since there is no load from the 1 side, it runs lightly on the rollers 9, 9 of the rail guide support member 8,
While being inserted and supported by the rail guide support member 8 of the other support column 5 across both sides of the upper part of the entrance/exit door 1, the other end surface comes into contact with the stopper 29 and stops, and the one end surface approaches the outermost support column 6. come into position.

In this way, move the rail 1 across entrance 1.
0, the door 11 is raised from the bottom of the guide groove 22 by switching the switching claw (not shown) of the ratchet 14a of the telescopic adjustment mechanism 14 and rotating the handle 14b back and forth. The rollers 20, 20 are brought into pressure contact with the lower flanges 10b, 10b of the moving rail 10, the door 11 is suspended, and the door 11 is moved toward the entrance/exit side.

Next, when the lower half of the doorway 1 is completely closed by the door 11, both front side ends of the door 11 are located on the back side of the pillars 4 and 5 on both sides of the doorway. , turn the handle 26 of the door tightening device 25 provided on the pillars 4 and 5 to release the press pin 2.
7, the pin 27 presses the center of the front end of the door 11, and the band-shaped packing 24 provided on the outer periphery of the back surface of the door 11 is connected to the guide groove and the band-shaped plate provided on the outer wall of the building on both sides of the entrance. 23 to close the entrance/exit 1 watertightly.

Next, when opening the door 11, the door 11 is released from the door 11 by the door tightening device 25, and then the door 11 is moved along the moving rail 10 toward the outer support 6, and the door 1 is closed. After opening, the door 11 is lowered and its lower end is grounded in the groove,
Thereafter, the moving rail 10 is moved to one side to the position of the stopper 30.

Note that the movement of the rail 10 and the door 11 may be performed not only manually but also electrically driven by an appropriate drive mechanism.

5 to 10 show another embodiment of the present invention, in which the outermost pillars 5,
One movable rail 10 that can be constructed over 6 spaces is used, but the feature is that it is composed of a fixed rail 40 and a movable rail 41 having dimensions obtained by dividing a rail of such length into two. It is.

That is, the fixed rail 40 and the movable rail 41 are
Openings 42 and 43 are provided at the center of the lower end along the entire length.
A fixed rail 40 is installed between a pair of rail support members 8' and 8' provided on one side of the entrance/exit 1, and a movable rail 41 is installed within this fixed rail 40. It is slidably inserted so that the entire length can be expanded and contracted.

To describe this structure in detail, the lower surface of the movable rail 41 is placed on movable rollers 44 that are rotatably provided on both outer sides of the inner bottom surface of the fixed rail 40, and the movable rail 41 is rotatably mounted on the upper surface of one end of the movable rail 41. A roller 45, which is pivotally supported, is received on the lower surface of the top plate of the fixed rail 40 so that the movable rail 41 can be moved easily, and rollers 45 are rotatably supported on the upper portions of both sides of the door 11 that opens and closes the entrance/exit 1. 20a and 20b on both sides of the lower surface of the moving rail 41 and the fixed rail 4, respectively.
The door 11 is mounted on both sides of the opening 42 of the opening 42 so as to be able to roll freely.

Although not shown on both sides of the upper part of this door 11,
A suspension member having a mechanism for adjusting the vertical movement of the door is provided and connected to the rollers 20a and 20b, and when the door 11 is closed, the door 11 is first moved downward to be supported on the bottom of the groove and then moved. The rail 41 is suspended horizontally at the entrance 1, and its tip is connected to the rail support member 8''.
Then, the door 11 is moved slightly upward to a state where it is suspended from the rails 40 and 41, and is moved toward the entrance/exit 1 side.

In addition, in the above embodiment, an example was described in which the door was installed at the entrance of a warehouse, etc., but it can be used not only for doors along walls like this, but also for entrances and exits of vehicles at construction sites, etc. In some cases, watertight mechanisms, guide grooves, tightening devices, etc. are not required.

Furthermore, when disposing the rail at the entrance of a warehouse or the like, it is not necessarily necessary to provide a support, and a rail support member such as a bracket may be fixed to the outer wall of a building such as a warehouse.

Furthermore, if the door is small, it is not necessarily necessary to provide a vertical movement adjustment mechanism.

As described above, in the present invention, the rail support members are arranged at the same height position on both sides of the entrance and on the horizontal extension line on one side of the position, and the entire length between the rail support members on one side of the entrance is the same as the opening of the entrance. A horizontal rail having a length at least twice the width is erected at an appropriate location so that the rail can be moved horizontally from one side of the doorway to the rail support member on the other side, and the door is grounded to the horizontal rail. In addition, since the invention relates to a horizontally sliding type door characterized in that a hanging member is slidably attached to the door so that it can be lifted, the rail can be freely moved in and out from the side of the entrance. Since it only needs to be installed at the entrance/exit when closing the gate, even if the installation height is low, it will not impede the passage of vehicles, etc., and in addition, the gate structure can be made low regardless of the height of the entrance/exit. , so it can be structurally formed into small-scale doors, and furthermore,
Since the door is opened and closed while suspended from the rail, it is not only easy to open and close the door, but also because the door is movable vertically relative to the rail. By lowering the door and touching the lower end to the ground, the upper and lower ends of the door are held by the ground plane and the rail, preventing rattling, and furthermore, the hanging member of the door is slightly lowered relative to the rail surface. Since the door can be lifted up, the weight of the door does not act on the rail, and only the rail can be easily moved horizontally.

In this way, since the movement of the rail and the movement of the door can be performed separately, even heavy doors can be manually operated.

Furthermore, even in cases where watertightness is required, such as with tide doors installed at the entrances and exits of warehouses along the coast, it is possible to easily create a watertight structure by lowering the door without being restricted by the position of the rail. Moreover, since the rotating parts are not immersed in seawater, there is no adverse effect due to rust or the like.
