Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a gate. In particular, the present invention relates to a gate having a configuration in which installation work is easy, but the gate body cannot be easily removed from the support post after the installation work.

[0002]

2. Description of the Related Art In a conventional gate, a column and a gate body are bolted and installed at least at two upper and lower locations (FIG. 1). Therefore, at the time of installation construction, first bolt the lower connecting part and support the gate body on the support,
Next, it was necessary to bolt the upper connection. In this case, the heavy gate body must be supported by a plurality of workers, and the work is not easy. Further, after the construction, the bolts of the connecting portion may come off intentionally or accidentally, and there is also a problem in terms of safety.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a gate having a connecting portion that can be easily installed and installed and that cannot be easily removed after the installation.

[0004]

According to the present invention, there is provided a gate comprising a column and a gate body attached to the column, wherein the column is provided at a lower position for mounting the gate body. A connection portion, wherein the gate body has a connection portion receiving portion for receiving the connection portion at a lower position thereof, and the connection portion receiving portion has an opening provided on a side surface of the gate body for receiving the connection portion. Part, and a counterbore portion that is cut from the opening to the upper side of the gate main body, and by fitting the connection portion to the counterbore portion through the opening portion of the connection portion receiving portion, the gate body is A gate is provided that can be easily connected to a column and supported so that it cannot be easily removed.

The connecting portion includes a U-shaped support member fixed to the side surface of the support column by welding or the like, and a columnar member provided between opposing side surfaces of the support member. Preferably, the portion and the counterbore portion are configured to receive and support the cylindrical member. Preferably, each corner of the opening and the counterbore has a curvature adapted to the shape of the cylindrical member so as to easily receive the cylindrical member.

Preferred embodiments will be described below with reference to the accompanying drawings.
The present invention will be described in more detail, but the present invention is not limited thereto.

FIG. 1 is a perspective view showing a connecting portion between a support of a conventional gate and a gate main body. FIG. 2 is a perspective view showing a connecting portion between the support of the gate and the gate body of the present invention. FIG.
FIG. 4 is a partial plan view showing a connecting portion receiving portion provided on the gate body.

In the conventional gate 1 'shown in FIG. 1, the support 2' and the gate body 3 'are connected to the support 2' and the gate body 3 '.
In the upper connecting position, the first connecting portion 2 on the side of the support 2 ′
2 ′ and the second connecting portion 32 ′ on the side of the gate main body 3 ′ are connected by bolts 23 ′, and attached to the outer peripheral surface of the support 2 ′ at a lower connecting position between the support 2 ′ and the gate main body 3 ′. The gate body 3 'is clamped by the U-shaped connecting portion 21', and the bolt holes 31 'provided in the gate body 3' and the bolts provided on the side surface 21a 'of the connecting portion 21' on the support 2 'side. Bolts and nuts 21b 'are passed through the holes and bolted at upper and lower coupling positions to support the gate body 3' on the support 2 '. A cover member 4 'for covering the first and second connecting portions is provided at a connecting position above the support 2'.
Are attached, but there is no cover in the lower connection position, and the bolts and nuts remain exposed.

FIG. 2 shows a gate 1 according to the invention. The gate 1 includes a column 2 and a gate body 3. Prop 2
Is provided with a first connecting portion 22 similar to that of FIG. The gate main body 3 is provided with a second connecting portion 32 similar to that of FIG. First connecting part 22
The connection between the second connection part 32 and the second connection part 32 is the same as in FIG. 1 described above.

At the lower part of the column 2, a U-shaped connecting portion 21 is provided.
Is provided. The connecting portion 21 includes a back surface 21 c attached to the support 2, a side surface 21 a protruding from the support 2,
And a cylindrical member 21b provided between the side surfaces 21a. The columnar member 21b is provided at a predetermined distance from the back surface 21c.

At the lower part of the gate body 3, a connecting portion 2
The opening 31a as shown in FIG.
And a counterbore portion 31b that is counterclockwise from the opening portion 31a toward the upper side of the gate body 3. Opening portion 31a
The counterbore portion 31b is of a size suitable for receiving the cylindrical member 21b, and each corner is chamfered at a predetermined curvature corresponding to the diameter of the cylindrical member 21b to facilitate receiving the cylindrical member 21b. .

The assembling of the gate according to the present invention involves first the gate body 3
Is moved horizontally so that the columnar member 21b of the connecting portion 21 of the column 2 is received in the opening 31a of the gate body 3. When the cylindrical member 21b is received in the opening portion 31a, the gate main body 3 is horizontally moved to the column 2 as it is. When the gate body 3 is pressed down vertically in the vertical direction when the cylindrical member 21b comes into contact with the end surface 31c of the opening portion 31a, the cylindrical member 21b fits into the counterbore portion 31b. Once fitted, the counterbore portion 31b is fixed to the columnar member 21b by the weight of the gate body 3. Due to the shape of the counterbore portion 31b that is cut in the upward direction of the gate body 3, the columnar member 21b cannot move in the horizontal direction, and as a result, the columnar member 21b is fixed in the counterbore portion 31b. After the column 2 and the gate main body 3 are fixed at the lower connecting position in this manner, the second connecting portion 3 of the gate main body 3 is connected at the upper connecting position as in the related art.
2 is fitted to the first connecting portion 22 of the support 2, and the first and second connecting portions 22 and 32 are fixed with bolts and nuts. Finally, the installation work is completed by covering the cover member 4 so as to cover the first and second connecting portions. Thus,
The upper connection position where the bolt is fixed is covered by the cover member 4 and therefore cannot be seen from the outside, and the lower connection position is connected without using a bolt.

[0013]

Therefore, in the gate of the present invention,
The need for bolting, which is difficult to work at the lower connection position, is eliminated, and only the upper connection position, at which the bolting operation is relatively easy, needs to be bolted, thereby facilitating installation work. In addition, the connection at the lower connection position is very easy because the gate body only needs to be moved horizontally toward the column and then pushed down vertically. Furthermore, since the bolts do not appear outside after installation, the design is excellent. In addition, since the bolt which is likely to come off does not appear to the outside, it is possible to effectively prevent the bolt from coming off intentionally or accidentally.

The above advantage is obtained by attaching the gate body 3 'to the support 2' in the conventional gate installation work.
First, the bolt hole 31 ′ of the gate body 3 ′ must be positioned at the connecting portion 21 ′ of the column 2 ′ at the lower connecting position and then bolted, and during this bolting operation, the heavy gate Must support the body,
There were problems such as the heavy burden on the workers, the fact that the bolts remained exposed after installation, which was undesirable in terms of design, and that the exposed bolts were easily or accidentally detached. If you think about it, it is very good.
