Description

  The present invention relates to a gate that can safely maintain a state in which a door body such as a sliding door for opening and closing the gate is stopped.

  In general, gates for opening and closing are provided at gates at the exterior of the building or at the boundary of the site. As a means for opening and closing the gate, for example, there are a form in which it is opened and closed by a gate door that is pivotally attached to the gate pillar, and a form in which it is opened and closed by a sliding door that moves between the gate pillars. Examples of the sliding door include a foldable form and a form formed long in the moving direction.

  Among them, the sliding door is often used in a place where the width of the gate is relatively wide. Therefore, the sliding door may be used not only in a fully opened state and a locked closed state, but also in a state in which the sliding door is opened halfway and a passage is secured. However, in this state, the sliding door may start even if the wind blows due to a slight inclination of the installation location.

  As a method for fixing the sliding door, for example, a dropping rod that can move up and down is attached to the main body of the sliding door, and the dropping rod is inserted into a receiving hole provided in the ground. In this case, the structure is simple and the cost is low, but the sliding door can be fixed only at the position where the receiving hole is provided. It is difficult to provide in an arbitrary place, and there is a possibility that dirt or dust accumulates in the receiving hole and it becomes difficult for the dropping rod to enter over time.

  For example, in Patent Document 1, a door is provided with a wheel at a lower portion of a door body and moves so that a passage portion can be opened and closed, and a brake pad that can contact the wheel and a brake pad that presses against the wheel are urged. An elastic member, and a braking means that always applies a braking force to one wheel, and a release means that is connected to a handle at the gate moving end and releases the braking force by swinging in the direction of the gate movement. A gate provided with a movement control device is proposed. This prevents the vehicle from running alone by the action of wind or the like.

Japanese Patent No. 4182202

  By the way, in the gate of the above-mentioned patent document 1, the movement control device has a wheel braking means. Since the wheel moves near the ground, dust or the like tends to adhere to it, and as a result, the braking force on the wheel decreases with time. There was a risk. In addition, the mechanism of the movement control device itself and the mechanism for interlocking with the wheels tend to be complicated in an environment where dust and the like are likely to adhere. It was.

  The present invention provides a gate device that can solve the above-described problems and can safely fix a sliding door in a state where a passage portion is secured.

In order to achieve the above object, the present invention is configured as follows.

  In the gate according to the present invention, the fixing device may be configured such that the sliding body of the sliding door is separated from the sliding door rail in a fixed state in which the sliding portion is fixed by bringing the contact portion into contact with the passage surface portion.

  According to the present invention, the fixing device has a contact portion that contacts the passage surface portion of the gate, the fixed state in which the sliding portion is fixed by bringing the contact portion into contact with the passage surface portion, and the contact portion from the passage surface portion. Since the state in which the sliding door can move away can be reversibly changed, if the fixing device is operated at a position where the sliding door is desired to run and be fixed, the sliding door can be fixed at that position. In addition, because the sliding door is subject to its own weight, even if the sliding door is forcibly moved with the sliding door fixed, a relatively large frictional force is easily generated between the contacting portion and the ground, and the sliding door is easily Does not move.

  In the present invention, if the sliding device is configured so that the sliding body is separated from the sliding door rail in a fixed state in which the sliding portion is fixed by bringing the contact portion into contact with the passage surface portion, the sliding portion is placed on the contact portion. Because of its own weight, even if the sliding door is forcibly moved with the sliding door fixed, a larger frictional force is likely to be generated between the contact portion and the ground, and the sliding door will not move more easily. preferable.
