2. Description of the Related Art Conventionally, most of gate-rotating gates use a hinge (hinge joint) at a connection portion of the gate body to the gate, and further use a thrust bearing in place of the hinge. Although they have been developed, all have the following problems.

[0003]

That is, when a hinge is used, the hinge portion may be damaged or come off at an early stage, so that the width of the gate body is limited to a relatively small width. In addition, since the hinge appears outside, there is a problem that the appearance is not preferable.

[0004] Further, even a system using a thrust bearing is not sufficient in strength, and therefore, for example, a width of 4.7.
For relatively large gates, such as m, doors or support wheels must be installed there to support the free end of the gate body, and guide rails for such doors must also be installed on the ground. . Further, reinforcing materials such as hanging wires were sometimes used.

In view of such circumstances, the present invention solves the above-mentioned problems of the prior art, and is excellent in design and has excellent strength. An object of the present invention is to provide a gate post-rotating gate having a structure that can be made compact without using wires or the like.

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a main part of a gate post-rotating type gate according to the present invention. A gate post 1 supporting a gate main body has a two-layer structure of an inner cylinder 11 made of a cylinder and an outer cylinder 12 surrounding the same. The outer cylinder 12 is rotatable with respect to the inner cylinder 11.

As shown in FIG. 5, the entire structure of the gate comprises a gate post 1 and a gate main body 2, as shown in FIG. 5, and the gate main body 2 is attached to the gate post 1 on one side. In this example, there is provided one gate body 2 which is formed in an appropriate shape from a vertical member or a lattice-like member, and when closed, the other side of the gate body 2 is latched on the gate pillar 3 on that side. It is locked with. When the opening width of the gate is large, a pair of the gate post 1 and the gate body 2 can be symmetrically arranged.

This gate post-rotating gate is characterized by a gate post 1 that supports a gate main body 2, and as shown in FIG.
The inner cylinder 11 is vertically fixed to the ground, and the outer cylinder 12 covers the inner cylinder 11 in a rotatable state. The fixing of the inner cylinder 11 can be appropriately performed according to the conditions such as the installation position of the gate, but in this example, the inner cylinder 11 is fixed to the upper base plate 4 by welding vertically, and the lower base plate with the anchor bolts 6 attached thereto. 5 is fixed to the ground with concrete, and then the upper base plate 4 is fixed on the lower base plate 5 with bolts 7. The “ground” here
The term includes not only the ground but also concrete or pavement surfaces.

The gate main body 2 is fixed to the side surface of the outer cylinder 12, and the fixing is usually performed by connecting bolts and nuts to door mounting brackets provided at their upper and lower positions. A gap is provided between the outer cylinder 12 and the inner cylinder 11 so that the outer cylinder 12 can rotate with respect to the inner cylinder 11. And a bearing 14 fixed to the upper end of the inner cylinder 11 directly below the fulcrum shaft 13, and the lower end of the fulcrum shaft 13 is received by the bearing 14.

The fulcrum shaft 13 is installed on a support plate 15 fixed inside the upper portion of the outer cylinder 12 so as to project downward.
Preferably, as shown in FIG. 2, a screw is formed on the outer periphery of the fulcrum shaft 13 and a tapped hole is provided in the support plate 15 so that the support shaft 15 is attached by screw connection and using a nut 16. The bearing 14 is also fixed to a support plate 17 fixed to the upper end of the inner cylinder 11. The fulcrum shaft 13 may be fixed to the support plate 15 by welding, for example. However, if the fulcrum shaft 13 is screwed as described above, the height position of the fulcrum shaft 13 can be slightly adjusted, and therefore, There is an advantage that the height position of the gate body 2 can be finely adjusted via the tube 12.

Since the lower end of the fulcrum shaft 13 abuts on the upper surface of the bearing 14, the lower end 13a of the fulcrum shaft 13 is made spherical as shown in FIG. The bearing 14 is formed into a convex shape, and the surface 14a of the bearing 14 on which the fulcrum shaft 13 contacts is formed as a spherical concave surface. The upper end of the outer cylinder 12 is a cap 1 of an appropriate shape.
The lower end of the outer cylinder 12 is separated from the upper base plate 4 or the ground as shown in FIG.

A stopper is provided to prevent the gate body 2 from rotating in the reverse direction. In this gate, the stopper can be provided in the gate post 1. That is, such a stopper may be provided so as to limit the rotation of the outer cylinder 12 with respect to the inner cylinder 11. Therefore, for example, the stopper may be provided at an appropriate position between the upper end of the inner cylinder 11 and the inner surface of the outer cylinder with respect thereto. Preferably, as shown in FIGS. 2 and 4, a gap between the inner cylinder 11 and the outer cylinder 12 is set to an appropriate size, and a pair of stopper members 19 are positioned at the same height and angularly displaced therebetween. , 2
0, one of which is fixed to the outer surface of the inner cylinder 11 and the other 20 is fixed to the inner surface of the outer cylinder 12, and when these members abut each other as shown in FIG. Further rotation is prevented. In addition, 21 in FIG. 4 is a drop bar fixed when the gate is closed.

The gap between the inner cylinder 11 and the outer cylinder 12 is
It has an appropriate size for mounting the color ring in a state where the outer cylinder 12 can be turned. Specifically, as shown in FIG. 2 and FIG. The coloring rings 22 and 23 are integrally provided so that there is a slight gap between the outer ring 12 and the inner peripheral surface. These collar rings 22 and 23 are preferably fixed to the outer peripheral surface of the inner cylinder 11 by shrink fitting or screwing, but may be provided on the inner peripheral surface of the outer cylinder. By providing such a color ring, the contact portion between the inner cylinder 11 and the outer cylinder 12 is limited to the fulcrum shaft 13 and the collar rings 22 and 23, so that the rotation of the outer cylinder 12 is stabilized and smoothly. Become.

When the gate is closed, the stopper 20 on the outer cylinder 12 abuts the stopper 19 on the inner cylinder 11 as shown in FIG. In this gate, the gate body 2 is the outer cylinder 1
2, the outer cylinder 12 contacts each of the collar rings 22 and 23 on its side surface, applies a bending load to the inner cylinder 11, and applies an axial force to the inner cylinder 11 via the fulcrum shaft 13. Then, in this state, it is rotatably supported by the inner cylinder 11. Therefore, the axial force and the bending load act on different parts,
Has excellent strength. In the state shown in FIG.
When the gate 1 is raised, the gate body 2 is rotatable in the B direction.

When the gate body 2 is opened by rotating in the direction B in FIG. 4 or when the gate body 2 is closed by rotating in the opposite direction, the fulcrum shaft 13 is used.
, The inner surface of the outer cylinder 12 also contacts the collar rings 22 and 23, and the spherical convex portion at the lower end of the fulcrum shaft 13 abuts against the spherical concave portion of the bearing 14. As a result, the two members substantially constitute a pivot bearing, so that they rotate smoothly.

The structure of the gate post 1 is as follows.
This is easily performed by fixing the inner cylinder 11 to which the coloring rings 22 and 23 are fixed to the ground, and then covering the outer cylinder 12 to which the fulcrum shaft 13 and the like are fixed from above the inner cylinder 11. The inner cylinder 11, the outer cylinder 12, and other components are made of metal such as steel or aluminum alloy. In an example of the approximate dimensions, the gate body is 156 cm high, 500 cm wide and 142 kg in weight.
In contrast, the diameter of the fulcrum shaft is 3 cm, and the inner cylinder of the gate post is 163
cm outer diameter 267mm wall thickness 6.6mm, outer cylinder height 180
cm outer diameter 318 mm wall thickness 6.9 mm. In this case, the maximum bending stress applied to the inner cylinder is applied to the lower end, and the value is 87 k at the tip (free end of the gate body) for safety.
Even if g is considered, it is about 400 kg / cm ² . In this case, the stress of the fulcrum shaft is 1290 kg / cm ² .

In this gate, the outer cylinder 12 is rotated when it is opened and closed. For example, by providing a gear or the like to the outer cylinder 12 and rotating it by an electric motor, the rotation of the outer cylinder 12 is driven by power. By doing so, there is an advantage that the opening and closing can be easily automated.

[0024]

According to the present invention, the pivoting gate of the present invention is constructed such that the load of the gate body is substantially controlled by the mechanism of the pivot bearing by abutment between the fulcrum shaft and the bearing of the inner cylinder receiving the fulcrum shaft via the outer cylinder. An axial load is applied to the cylinder, but at the same time, the load received by the bearing mechanism is substantially reduced by the contact of the collar rings provided above and below the gap formed between the inner cylinder outer periphery and the outer cylinder inner periphery. In this way, the gate main body maintains a sufficient strength to enable stable and smooth rotation about the fulcrum shaft.

Further, since the rotating mechanism including the fulcrum shaft and its bearing is placed in a double cylinder, it is preferable in appearance and has excellent durability without being exposed to wind and rain. In addition, because of its excellent strength, even for relatively large gates, there is no need to provide a door wheel at the lower end of the gate body, so there is no need to install a guide rail for the door wheel, making it compact. It is easy to clean, and it is preferable in terms of design.
