Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence formed by connecting a plurality of vertical members fixed to an installation surface with a connecting member.

[0002]

2. Description of the Related Art Conventionally, the following fences are generally used as this kind of fence. That is, a large number of vertical members are fixed to the ground, and a horizontal member is fixed to each vertical member by bolts and nuts.

[0003]

By the way, for example, in the case of farmland facing a road, it is necessary to use a tractor to drive from the road to the farmland when carrying out farm work.
However, when the fence as described above is provided between the farmland and the road, it is necessary to bypass the place where the fence is not provided and enter the farmland, which is complicated.

[0004] Therefore, it is an object of the present invention to provide a fence that normally prevents passage and can easily be made to permit passage when necessary.

[0005]

In order to solve this problem, the invention according to claim 1 is a fence formed by connecting a plurality of vertical members fixed to an installation surface by a connecting member. The connecting member between at least two adjacent vertical members of the plurality of vertical members is attachable to and detachable from the two vertical members. Here,
The phrase "the connecting member is attachable / detachable to / from the vertical member" does not necessarily mean that the connecting member is directly attachable / detachable to / from the vertical member, but also includes indirectly attachable and detachable members. That is, the case where another member is connected to the vertical member and the connecting member is detachable from the other member is also included. Also, "vertical material"
Is not limited to a vertical one, but includes an inclined one. Further, the "connecting member" is not limited to a horizontal member that is substantially horizontal or parallel to the installation surface, but includes an inclined member. Also, the "installation surface" is not limited to the ground,
Floors formed at a position higher than the ground are also included. Also,
It is not limited to a substantially horizontal one, but includes a sloped one such as a slope.

According to the present invention, the detachable connecting member is removed from the two vertical members so that the two vertical members are in a passable state without the connecting member. As described above, according to the present invention, the passage is normally blocked, the passage is permitted when necessary, and it is possible to move between the places partitioned by the fence, which is convenient.

The invention according to claim 2 is the invention according to claim 1, wherein each end of the removable connecting member is
The detachable connecting member is detachable from each of the two vertical members, and each end of the connecting member is engaged with each of the vertical members between the two vertical members. It is movable between a mating engagement position and a non-engagement position where the one end portion of the connecting member and the vertical member are disengaged from each other, and the connecting member is moved by the urging force of an elastic body. It is characterized by being located in.

In the present invention, the invention according to claim 1 is realized more specifically. That is, normally, the detachable connecting member is positioned at an engaging position where each end portion thereof engages with each vertical member by the biasing force of the elastic body. Therefore, the fence normally blocks traffic. Then, when it is desired to pass, the connecting member is moved to the non-engaging position against the biasing force of the elastic body, and the engagement between the one end portion and the vertical member is released, and then, The engagement between the other end and the vertical member is released, and the connecting member is removed from both vertical members. In this way, the connecting member can be easily removed from between the two vertical members, and passage is ensured when necessary.

Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the fence is installed between the farmland and the road, and has a large number of vertical members 10 and horizontal members 30 (connecting members). And it has a fixed part and a removable part. The detachable part is formed between two adjacent vertical members 10.

Each of the vertical members 10 is fixed at a predetermined interval in a state of being vertically inserted into the ground (installation surface). The vertical member 10 is formed of a round pipe whose upper end is closed.

Three brackets 20 are fixed to each vertical member 10. As shown in FIGS. 2, 3 and 5, each bracket 20 has a short tubular shape. Then, each vertical member 10 (on the road side) is fixed substantially horizontally through a bolt hole 22 and a bolt 23 and a nut 24 (including a washer (not shown)). As shown in FIG. 5, bolt holes 26 are provided at both ends of the bracket 20, respectively. As shown in FIG. 3, each bolt hole 26 is provided so as to be vertically pierceable on the corresponding upper side and lower side of the bracket 20.

As shown in FIG. 1, the horizontal members 30 are the vertical members 1.
It is installed horizontally to connect 0s. Each vertical member 10
Three stages are provided between them. All the cross members 30 have a round pipe shape.

As shown in FIG. 4 (a), bolt holes 32 are formed at both ends of the horizontal member 30 (fixed horizontal member 30A) in the fixed portion.
Is provided. Each bolt hole 32 has a fixed cross member 30A.
The corresponding upper side and lower side of the above are provided so as to be vertically pierceable. As shown in FIGS. 2 to 4 (a) and FIG. 5, each fixed transverse member 30A has its end inserted into the bracket 20, and the bolt hole 26 of the bracket 20 and the fixed lateral member 3A.
A nut 34 is screwed through a washer 35 into a bolt 33 inserted through the bolt holes 32, 32 of 0A and the bolt hole 26 of the bracket 20 and fixed to each bracket 20.

On the other hand, as shown in FIG. 4 (b), notches 36 are provided at both ends of the horizontal member 30 (the removable horizontal member 30B) in the removable portion. The notch portion 36 extends in the length direction of the removable horizontal member 30B. Each notch 36
Are similarly provided on the corresponding upper and lower sides of the removable horizontal member 30B.

The removable horizontal member 30B is attached to the bracket 20 as follows. FIG. 2, FIG. 3, FIG.
(b) As shown in FIG. 5, the bolt hole 2 of the bracket 20
Bolts 37 are inserted into the screws 6, 26, and nuts 38 are screwed into the bolts 36 via washers 39. And
The notch 36 of the removable cross member 30B is engaged with the bolt 37. The same applies to the notches 36 at both ends.

The removable cross member 30B is movable in its length direction between an engagement position (see FIG. 5) and a non-engagement position (see FIG. 5). What is the engagement position?
As shown in FIG. 5, it is a position that is not biased in the longitudinal direction between the both vertical members 10 and that is provided with the notch portions 36 of both.
Is the position to engage with each bolt 37. As shown in FIG. 6, the non-engagement position means that the notch 36 is engaged with the bolt 37 and the other notch 36 is located between the both vertical members 10 with a deviation in the longitudinal direction thereof. Notch 36 is bolt 3
It is the position where the engagement with 7 is released. In this fence, all are provided symmetrically, so removable crosspieces 30
Even if the lengthwise direction of B is biased, the non-engagement position is obtained.

As shown in FIG. 5, a compression spring 40 is provided on the bracket 20 having a fixed cross member 30A provided on one side and a removable cross member 30B provided on the other side. The compression spring 40 is interposed between the bolt 33 on the fixed horizontal member 30A side and the end of the removable horizontal member 30B. At both ends of the removable horizontal member 30B,
It is done like this. For this reason, the removable horizontal member 30B
Is normally located at the above-mentioned engagement position (see FIG. 5) by the biasing forces of the compression springs 40 at both ends (the biasing forces are almost the same).

Next, the function and effect of this fence will be described. As described above, normally, the removable horizontal member 30B is located at the engagement position by the urging force of the compression springs 40 provided at both ends of the removable horizontal member 30B, and the vertical members 10 (removable part) pass through. Is prevented (see FIGS. 1 and 5).

On the other hand, when it is desired to pass between the vertical members 10 (removable portion), as shown in FIG. 6, one of the removable horizontal members 30B is resisted against the biasing force of the compression spring 40. It is positioned at the non-engagement position, and the engagement between the notch 36 and the bolt 37 is released. Then, as shown in FIG. 7, thereafter, the space between the other notch portion 36 and the bolt 37 is removed, and the detachable horizontal member 30B is removed from between the vertical members 10. In this way, by removing the upper and lower three removable horizontal members 30B between the vertical members 10, passage is allowed between the vertical members 10 (removable parts), and the tractor moves from the road to the farmland. It is possible to get in and go the other way.

In the above, the embodiment in which two adjacent vertical members 10 are detachable parts is shown, but the present invention is not limited to this, and three vertical members 10 are detachable parts. Good. In that case, with respect to the bracket 20 at the center, the removable horizontal members 30B are provided on both sides thereof. Further, such a fence can be installed not only between the farmland and the road but also in various places.
