Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sliding door used for a park, a factory entrance, and the like.

[0002]

[Prior Art]

 Conventionally, as the above-mentioned sliding door, for example, a door body having a pulley at the lower end to run on a rail installed on the ground between gate poles, or a door body having wheels at the lower end is used. In some cases, the vehicle was designed to run in a groove provided on the ground between the gate posts, or the door body having wheels at the lower end described above was designed to run directly on the ground.

[0003]

[Problems to be solved by the device]

 However, with the conventional slide doors described above, when a rail is installed on the ground, there is a possibility that a person passing between the gateposts may get caught in the rail, and in the case of a groove on the ground. Since dust and dirt enter the groove, maintenance is required to ensure smooth running of the door body.In addition, if the door body is designed to run directly on the ground, Depending on the situation, the door body may be hindered from running, and the conventional problem was to solve these problems.

[0004]

[The purpose of the device]

 This invention was made with attention to the above-mentioned conventional problems, and it does not hinder the passage of people and vehicles, and can always perform smooth opening / closing operations without requiring maintenance. The purpose is to provide a sliding door.

[0005]

[Means for Solving the Problems]

 A sliding door according to the present invention comprises a horizontally fixed beam and a door body which is slidably mounted on the fixed beam so as to be slidable along the longitudinal direction and extendable from the fixed beam. The present invention is characterized in that the structure is provided, and such a structure of the sliding door is a means for solving the above-mentioned conventional problems.

[0006]

[Function of the device]

 Since the sliding door according to the present invention has no rails or grooves on the ground, it does not hinder the passage of people or vehicles, and no special maintenance is required.

Further, since the door body is suspended by the fixed beam, the opening / closing operation of the door body becomes smooth even if the ground has some irregularities.

[0008]

【Example】

 The invention will be described below with reference to the drawings.

1 to 5 show an embodiment of a slide door according to the present invention. A slide door 1 shown in the drawings is an I bridge installed between upper ends of a pair of columns 2 and 2 standing on a ground E. A fixed beam 3 made of shaped steel and a door body 11 supported by the fixed beam 3 and having substantially the same length dimension as the fixed beam 3 are provided, and the columns 2 and 2 are provided along a wall (not shown). Have been set up. As shown in FIG. 2, the column 2 has a substantially arched shape, and supports the girder 2a with the upper flange 3A of the fixed beam 3 in contact with the beam 2 through a liner 4. An intermediate support column 5 having the same shape is provided near the left support column 2.

As shown in FIG. 4, the fixed beam 3 extends downward on both sides of its tip (left end in FIG. 1) via base plates 6 and 6 fixed between upper and lower flanges 3A and 3B. Roller holding plates 7 and 7 are provided so as to face each other, and the extending portions of the roller holding plates 7 and 7 are supported by roller shafts 9 and 9 via bearings 8 and (8). Rollers 10 are provided.

On the other hand, the door body 11 is provided with a plurality of vertical grids 14 between the upper frame 12 and the lower frame 13, and in this case, the upper frame 12 is made of I-shaped steel like the fixed beam 3. Has become. Then, on both sides of the base end of the upper frame 12, as shown in FIG. 5, roller holding plates 16 extending upward through base plates 15, 15 fixed between the upper and lower flanges 12A, 12B. 16 are provided so as to face each other, and rollers 18 and 18 supported by roller shafts 17 and 17 are also provided at the extending portions of these roller holding plates 16 and 16, and the door body 11 is As shown in FIG. 3, the rollers 10, 10 on the fixed beam 3 side are respectively brought into contact with the lower surface of the upper flange 12A with the web 12C of the upper frame 12 interposed therebetween, and the rollers 18 on the door body 11 side. , 18 are respectively brought into contact with the lower surface of the upper flange 3A with the web 3C of the fixed beam 3 in between, so that they can slide along the longitudinal direction of the fixed beam 3, that is, from the tip of the fixed beam 3. To extend It is to be so.

Further, by providing roller bearings 19 and 19 which contact the upper surface of the lower flange 3B of the fixed beam 3 inside the roller holding plates 16 and 16 of the upper frame 12, respectively, the fixed beam 3 and the door body are provided. In addition to preventing rattling between the doors 11, a stopper 20 is provided at a position near the intermediate column 5 of the web 3C of the fixed beam 3 to prevent the door body 11 from falling off.

Further, as shown in FIG. 2, horizontal rollers 21 and 21 are provided on the respective facing surfaces of the pillar portions 2b and 2b of the support column 2 so that the door body 11 can be operated more smoothly. There is.

Therefore, in the slide door 1 having such a configuration, since no rail or groove is provided on the ground, there is no obstacle to the passage of people and vehicles, and no special maintenance is required.

Further, since the door body 11 is suspended on the fixed beam 3, the opening / closing operation of the door body 11 can be smoothly performed even if the ground E has some irregularities.

In addition, in the above-mentioned embodiment, the single-opening type sliding door 1 provided with one door body 11 is illustrated, but the present invention is not limited to this, and the columns 2 and 2 on the left side of FIG. It is also possible to provide the fixed beam 3 and the door body 11 by providing the above, and to make it a double-opening type sliding door.

[0017]

[Effect of the device]

 As described above, in the sliding door according to the present invention, the horizontally fixed beam and the fixed beam are slidable along the longitudinal direction of the fixed beam and can be extended from the fixed beam. Since it is equipped with a door that is installed in a closed state, it does not impede the passage of people or vehicles, and it does not require maintenance and can be opened and closed smoothly at all times. That brings a very good effect.
