Description

DETAILED DESCRIPTION OF THE INVENTION The purpose of the present invention is to provide a gate mechanism that easily obtains a highly accurate and sophisticated finish in relation to an improved construction method for a door mechanism disclosed in Japanese Patent Publication No. 57-53507. be.

The outline of the invention cited in the cited publication is as follows.

Figure 1 (l) where J is the decorative board (door), 2.2 is the support arm, 3.3 is the support column 1.4 is the compression submergence/g, 5.5
S is a pivot point that allows the support arms 2, 2 to rotate freely within a plane that includes the pillars 3, 3, respectively, and S is the ground surface. As is clear from FIG. 1, the door 1 is opened and closed by rotating the door 1 in the direction of the arrow a, but various problems arise in actual construction.

That is, depending on whether the pivot points 5,5 are at the same height with respect to the ground surface S, and whether or not the support arms 33 are both vertical (parallel), the support arms 2,2 are attached to the pivot points 5,5, 5, there is a significant relationship between whether or not it rotates smoothly. In the past, this type of construction required highly accurate precision surveying, and trimming and other repairs after construction required a considerable amount of time and effort.

According to the present invention, even a low-skilled worker can quickly and easily obtain a beautiful finished construction with high quality.

The structure of one embodiment of the gate mechanism according to the present invention will be described with reference to the drawings. In FIG.
2, and one end 21b, 22b of the two support arms 21, 22 in the direction of the arrow, respectively.
Decorative board 1, which can be regarded as a substantially rigid body, is fixed as a part of the surface perpendicular to 22, and support arm 21 of upper construction.
・The other end 21a22a of 22 is the other end 21a of the respective other end 21a.
- Respective shaft support mechanisms 51 and 52 that are rotatable about the axis X connecting 22a, and the respective shaft support mechanisms 51 and 5
2 at the same height from the ground surface S.
32, the above-mentioned decorative board 1 before gate construction is configured to be removable from the support arm 2122 of the upper construction, and also to be detachable in a certain positional relationship from the support arm 3132 of the upper construction. The structure is characterized by the following.

Note that 4 is a spring that biases the support arm 21 in a direction away from the ground surface S. Furthermore, the details of the specific configuration of "detachable" may be any of various mechanisms that are already well-known and commonly used techniques. Although there is no need to elaborate, a few examples will be described below.

For example, as shown in FIG.

Figure 4). Also, instead of the holes 11, 11, 12, and 12, male screw pieces 11b and 12b are planted in the decorative board 1, and the screw pieces 11

・After inserting it into hole 32, it goes without saying that it can be tightened with a wing nut or the like (Fig. 5).

In any case, the relationship between these two or three embodiments is merely a change in role.

Since the present invention has the above configuration, it may be considered that the gate construction vehicle, the door, that is, the decorative board 1 is removed from the support arms 21 and 22, and the support boom 2122 and the decorative board 1 are sent separately in advance. ), temporarily fix the second pillars 31 and 32 to the decorative board 1. At this time, this pillar 31 and
The positional relationship of 32 is the second pillar 3 required after construction.
The positional relationship of the perforation 1112 of the decorative board 1 and the female screw portion 31a32a is determined in advance so that the positional relationship is exactly the same as the ideal positional relationship of 1.32. ), we will proceed with the construction work to plant the second pillars 31 and 32 on the ground surface S.

When the fixing of the second support posts 31 and 32 to the ground surface S is completed, the decorative board 1 is removed from the second support posts 31 and 32,
It is fixedly engaged with one end 21b22b of the abrasive support arm 2122, and acquires the position where it should originally function as a door. As is already clear, this process does not require any special tools or skills, and the labor and installation time are minimal, and the effect is even greater when the decorative board 1 is installed on the ground surface S of the second support 3132. Since it functions as a robust and accurate jig, it is possible to finish the construction work beautifully and precisely. The constructor is freed from the trouble of adjusting and modifying the smoothness of operation, which is the most troublesome part of gate construction, and the benefits are great.
