[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a racetrack, a racetrack, a ranch, a park, and other general fence entrance / exit structure.

[0002]

[Prior art]

 For example, racetrack field fences are traditionally made of wood and are rounded to avoid scratching the horse when it comes into contact. In recent years, from the viewpoint of durability, safety, aesthetics, etc., instead of wood, it is being replaced with a lightweight metal material such as aluminum alloy.

The entrance of the fence where human horses enter and exit includes a shut-off type and a narrow entrance where only part of the fence main body can be opened and closed with a hinge, but when the entrance of the fence is as wide as about 6 m, it is heavy. Therefore, such a structure is unreasonable in terms of operation and strength.

[0004] Therefore, there are some doors that can be opened and closed by expanding and contracting the fence member, but there is a step between the end of the outer member and the insertion member that may contact the horse, and the horse is damaged. There are drawbacks.

There is a slide type structure that avoids the above problems. This is a structure in which a guide rail is installed in parallel with the fence body, and the operating fence is opened and closed according to this guide rail.When the fence is opened, it is placed on the guide rail of the fence body, and when closed, it is placed on the same level as the fence body. As a result, the device is a large one equipped with moving gears and the like, and there is a drawback that it is inevitably expensive.
