  However, as described above, when the lateral movement of the door body is guided by a rail or a door groove provided on the bottom surface of the open part, particularly when the door body is guided by the door groove, the door accumulates dust in the door groove. There was a problem that the body could not move sideways smoothly.

  In view of the above circumstances, an object of the present invention is to provide a lateral pulling gate that can be suitably laterally moved while guiding a door body.

  In order to achieve the above object, the present invention provides the following means.

The lateral pulling gate of the present invention is a lateral pulling gate that opens and closes the gate by moving the door horizontally, and one door stop provided with a recess for storing the door when the gate is opened is the open portion of the gate. Is provided on one side of the gate, and the other door stop is provided with a recess with which the front end of the door body that is moved laterally from the one door contact when the gate is closed is engaged. It is provided on the other side across the opening, and at least one of the doors of the doors abuts against and supports the door body, and guides the door body to the side. A plurality of roller members to be moved are provided , and at least one of the doors per door is located on an inner surface that forms the recess located on the side on which water pressure acts when the gate is closed. One of the doors facing the inner surface Wherein the biased so as to contact the watertight member to fill the gap between the door body is provided in the.

  In the present invention, the door member is supported by the roller member provided per door and can be moved laterally while being guided.

  In this invention, by providing a watertight member on the inner surface of the hydraulic pressure side of the door, when the gate is closed, it is ensured that the blocked water leaks through the gap between the inner surface of the door and one surface of the door body. Can be prevented.

  Further, conventionally, a watertight rubber (watertight member) is attached to one surface of the door body, and the watertight rubber is provided so as to contact the inner surface of the door stop, thereby ensuring the watertightness of the gap. When such a configuration is applied to the lateral pulling gate according to the present invention, there arises a disadvantage that the watertight rubber moves laterally together with the door body and comes into contact with the roller member that guides the door body. On the other hand, in the present invention, since the watertight member is provided not in the door body but in the door, the watertight member is fixed to the moving door body, and such a watertight member ensures the watertightness of the gap. The door body can be preferably guided by the roller member.

  According to the lateral pulling gate of the present invention, the door body is supported by the roller member provided per door and can be moved laterally while being guided, so the door body is moved laterally like a conventional rail or door groove. There is no fear that it will not be possible, and the door can be moved laterally in a suitable manner at all times.

  Further, as shown in FIGS. 2 and 4, a plate-like watertight rubber (watertight member) 21 extending in the vertical direction is attached to the inner surface 2 d of the upstream side S <b> 4 in the storage dock 2 of the present embodiment. Yes. The watertight rubber 21 is provided with the end on the rear end 2c side of the storage dock 2 fixed to the inner surface 2d. Further, since the interposition member 22 is interposed between the inner surface 2b and the watertight rubber 21, the end portion side on the front end 2b side is elastically deformed and bent toward the one surface 1a of the door body 1. And the part bent by the interposition member 22 is urged | biased and contact | abutted by the one surface 1a of the door body 1, and this, The clearance gap between the one surface 1a and the inner surface 2b of the door body 1 is filled. The watertightness of the gap is ensured.

  On the other hand, as shown in FIGS. 1, 2, and 5, a plurality of roller members 23 are provided on the locking door door 3 on the distal end 3 b side on the opening portion S side (storage dock 2 side). Each of the plurality of roller members 23 is provided on each of the upstream side S4 and the downstream side S5 of the opening portion S with the recess 3a interposed therebetween (with the door body 1 interposed). In addition, the two roller members 23 of the upstream side S4 and the downstream side S5 are respectively provided on the upper end (upper surface 1f) side and the lower end (lower surface 1c) side of the door body 1, and are arranged side by side in the vertical direction. . Each roller member 23 is provided so as to be rotatable about an axis extending in the vertical direction of the rotation shaft fixedly supported by the locking door contact 3. Similarly, each roller member 23 is arranged so that a part of the roller surface protrudes from the inner surfaces 3c and 3d forming the recess 3a into the recess 3a. In the state where the door body 1 is engaged with the locking door stop 3 on the front end 1d side, the protruding roller surface is formed on the downstream surface S5 on the one surface 1a of the door body 1 in the roller member 23 on the upstream side S4. The roller member 23 is in contact with the other surface 1b of the door body 1 respectively. Thereby, the front end 1d side of the door body 1 engaged with the latch door 3 is supported.

  Further, in the locking door contact 3 of the present embodiment, a plate-like water-tight rubber (water-tight member) 24 extending in the vertical direction is provided on the rear end 3e side of the roller member 23 on the inner surface 3c on the upstream side S4. It is attached. Similar to the watertight rubber 21 of the storage dock 2, the watertight rubber 24 is provided with the end on the rear end 3 e side of the locking door 3 fixed to the inner surface 3 c on the upstream side S 4. By the interposition member 25 interposed therebetween, the end portion side on the front end 3 b side is elastically deformed and bent toward the one surface 1 a of the door body 1. Thereby, the watertight member 24 is urged | biased and contact | abutted to the one surface 1a of the door body 1, and the clearance gap between the one surface 1a and the inner surface 3c of the door body 1 is filled, and the watertightness of this clearance gap part is ensured.

  Further, as shown in FIG. 5, the locking door contact 3 is positioned in contact with the front end 1 d of the door body 1 in a state where the door body 1 is engaged and disposed at a predetermined open portion closed position. The stopper 26 projects from the bottom surface 3f of the recess 3a into the recess 3a. And in the state which positioned the door body 1 with such a stopper 26, the front-end | tip of the front-end | tip watertight rubber 9 attached to the front-end | tip 1d of the door body 1 contact | abuts to the bottom face 3f of the recessed part 3a, and watertightness of this part is ensured. Is done.

  Next, the operation and effect of the horizontal pulling gate A having the above configuration will be described.

  When the door body 1 stored in the storage dock 2 is laterally moved to close the opening portion S, first, the handle 7 of the door body 1 is rotated in one direction to move the wheel 6 to the door body 1. It protrudes downward from the lower surface 1c and is brought into contact with the bottom surface S3 of the opening S (the bottom surface of the storage dock 2). At this time, the door body 1 is lifted upward with the protrusion of the wheel 6, and the lower surface 1 c is separated from the bottom surface of the storage dock 2.

  And if this door body 1 is pulled out from the storage dock 2, the wheel 6 will rotate so that it may drive | work on the bottom face S3 of the open part S, and the door body 1 will move smoothly sideways. At this time, since the door groove is not provided on the bottom surface S3 of the open part S as in the case of the conventional lateral pulling gate, the door body 1 may not be able to move sideways straight toward the locking door stop 3. In the embodiment, a plurality of roller members 20 provided on the upstream side S4 and the downstream side S5 of the storage dock 3 abut on the one surface 1a and the other surface 1b of the door body 1, and these roller members 20 rotate around the axis. The door body 1 is supported. For this reason, the door body 1 that is moved laterally from the storage dock 2 and is pulled out is pulled straight out while being guided in a direction toward and away from the lock door 3.

  Here, in the conventional lateral pulling gate, a watertight rubber is attached to one surface 1a of the door body 1, and this watertight rubber is provided so as to abut against the inner surface 2d of the door stop (storage dock 2). The water tightness of the gap was ensured. That is, in the conventional horizontal pulling gate, the door body 1 moves sideways and the watertight rubber also moves horizontally. When such a configuration is applied to the horizontal pulling gate A of the present embodiment, the door body is moved. The watertight rubber comes into contact with the roller member 20 that supports and guides 1, and the door body 1 cannot be suitably laterally moved, and the watertight rubber is damaged. For this reason, in this embodiment, the watertight rubber 21 is attached not to the door body 1 but to the storage dock 2, and with this configuration, the watertight rubber 21 is fixedly provided to the moving door body 1. The watertightness of the gap can be ensured, and the door body 1 can be suitably guided by the roller member 20.

  Then, the front end 1d side (the front end portion) of the door body 1 that is suitably guided and protruded in this way is inserted into the recess 3a of the locking door contact 3 and the roller member 23 of the locking door contact 3 is The door body 1 is supported while rotating in contact with the one surface 1a and the other surface 1b of the door body 1, respectively. And the front-end | tip 1d of the door body 1 supported by the roller member 23 contact | abuts to the stopper 26, and the positioning of the horizontal direction T is made. At this time, since the tapered surface 9a is formed on the tip watertight rubber 9 attached to the tip 1d of the door body 1, the watertight rubber 24 attached to the inner surface 3c on the upstream side S4 is preferably formed on the one surface 1a of the door body 1. Each of the gaps between the door body 1 and the inner surface 3c of the upstream side S4, the bottom surface 3f of the recess 3a, and the door body 1 at the stage where the leading end watertight rubber 9 is guided against the bottom surface 3f of the recess 3a. Water-tightness of the part is ensured. Then, at the stage where the door body 1 is arranged in this way, the handle 6 of the door body 1 is rotated in the other direction to retract the wheel 6 from the lower surface 1c of the door body 1 (retract upward). Along with this, the door body 1 moves downward by its own weight, and the bottom surface watertight rubber 8 attached to the lower surface 1c abuts against the bottom surface S3 of the open portion S to ensure the watertightness of this portion. Finally, the drop bar 12 is inserted through the through hole 10 of the door body 1 and the locking hole 11 of the bottom surface S3 of the opening S. As a result, the opening S is closed by the door body 1 that is supported by the storage dock 2 on the rear end 1e side and the stopper door stop 3 on the front end 1d side.

  On the other hand, water pressure acts on the door body 1 arranged in this way from the upstream side S4 of the opening S, and the door body 1 is pressed to the downstream side S5. Thereby, the front surface 1d side and the rear end 1e side of the one surface 1a of the door body 1, the storage dock 2 that supports the front end 1d side and the rear end 1e side, and the inner surface 2d of the upstream side S4 of the locking door contact 3 respectively. 3c becomes large. On the other hand, in this embodiment, the watertight rubbers 21 and 24 provided on the inner surfaces 2d and 3c of the storage dock 2 and the locking door contact 3 are urged toward the one surface 1a of the door body 1. Therefore, even when the gap is enlarged by the action of water pressure, these watertight rubbers 21 and 24 are securely adhered to the one surface 1a of the door body 1, and the watertightness of this portion is ensured. Thereby, the water of the closed open part S does not leak to the downstream S5 through the gap between the door body 1, the storage dock 2, and the locking door contact 3.

  Therefore, according to the lateral pulling gate of the present embodiment, the door member 1 is supported by the roller members 20 and 23 provided in the storage dock 2 and the locking door contact 3, and the door body 1 is horizontally moved while being guided by these. Since it can be moved, there is no possibility that the door body 1 cannot be laterally moved like a conventional rail or door groove, and the door body 1 can be laterally moved suitably at all times.

  Further, by providing the watertight rubbers 21 and 24 not in the door body 1 but in the storage dock 2 and the lock door stop 3, the door body 1 is preferably guided by the roller members 20 and 23 while ensuring the watertightness of the gap. Is possible.

  In addition, this invention is not limited to said one Embodiment, In the range which does not deviate from the meaning, it can change suitably. For example, in this embodiment, eight roller members 20 and 23 are provided in the storage dock (per door) 2 and eight in the locking door (other door) 3. If the body 1 can be moved laterally while being supported and guided, it is not necessary to limit the number and arrangement of the roller members 20, 23 provided in each door 2, 3, and only one door door 2 has a roller member. 20 may be provided.
