Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pipe fence, and more particularly to a pipe fence that can be suitably used as a boundary fence in a park or the like as well as a guard fence installed between a road and a sidewalk or in a median of a roadway. It is.
[0002]
[Prior art and problems to be solved by the invention]
Conventionally used fences such as guard fences installed between roads and sidewalks and boundary fences for parks, etc., as shown in FIG. The frame members 33 and 34 and the intermediate vertical member 35 provided at a predetermined interval between them are fixed by welding. Since it is manufactured in such a fixed manner, when applied to flat ground, the fence can be manufactured in a rectangular shape in advance, and the fence can be constructed quickly.
[0003]
However, each time the fence with the above configuration is applied to an inclined land, it is manufactured in a parallelogram shape along the inclined land, or the slope of the inclined land is predicted in advance so that it can be applied to the inclined land in steps of several degrees. It is necessary to take measures such as However, even when the latter is manufactured in increments of several degrees, it is difficult to predict gradients that are frequently used and gradients that are rarely used, and inventory management is difficult. There are problems such as becoming longer.
[0004]
On the other hand, it is also conceivable to provide a bolt insertion hole at the intersection of the upper and lower frame members and the frame members and vertical members at the left and right ends, and connect with bolts and nuts to form a fence. Although it can be applied, the bolts and nuts are visible and poor in appearance when constructed. It is particularly unsuitable for applications where a good landscape is desired.
[0005]
[Problems to be solved by the invention]
The present invention has been made to solve the above-mentioned problems, and the object thereof is applicable to not only flat land such as roads and parks but also sloping ground, and provides a pipe fence having a good appearance. Is.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a pipe fence according to the present invention (Claim 1) is provided on left and right frame pipes that are attached with metal fittings interposed between standing columns and above and below the left and right frame pipes. A pipe fence comprising upper and lower frame pipes, and vertical pipes provided in the spaces in the upper, lower, left and right frame pipes in parallel to the left and right frame pipes at a predetermined interval. The pipe is provided with a connecting member at the end of the pipe, and the connecting member is loosely inserted into openings provided at predetermined intervals on the pipe walls of the upper and lower frame pipes, and is removed from the upper and lower frame pipes. The stopper member is prevented from coming off and connected to the upper and lower frame pipes.
[0007]
In the above configuration, the upper and lower frame pipes, the left and right frame pipes, and the vertical pipe are provided with connecting members provided at the pipe ends of the left and right frame pipes and the vertical pipe at predetermined intervals on the pipe walls of the upper and lower frame pipes. Since it is loosely inserted into the opening and connected by being retained by the retaining members provided on the upper and lower frame pipes, within the range of play of the connecting member loosely inserted in the opening, from the flat ground It can be applied to slopes with a slope of more than 10%, and it has a good appearance with no protrusions such as bolts and nuts at the connecting part.
[0008]
Further, although not particularly limited, the connecting member is a bar having a size that can be inserted into the left and right frame pipes or vertical pipes, and is pulled out to the outer periphery of a substantially central portion in the axial direction of the bar. It is desirable that a groove is formed in which the stop member is engaged (Claim 2). With such a connecting member, while it is loosely inserted into the upper and lower frame pipes up to the groove, a shape member such as a lip groove steel is inserted from the pipe end of the upper and lower frame pipes, and the lip is inserted into the groove. Retaining can be achieved by engaging the portions. Alternatively, it is made of a disc-like flexible material having a through hole in the center, and a groove that engages with the wall of the opening of the upper and lower frame pipes is formed on the outer peripheral surface, and the connecting member is formed on the inner peripheral surface of the through hole. Even if the retaining member (Claim 3) in which a convex portion engaging with the groove is formed, the retaining can be achieved.
[0009]
The pipe fence according to the present invention (Claim 4) is composed of upper and lower frame pipes that are attached with metal fittings interposed between standing columns and vertical pipes that are provided at predetermined intervals between the upper and lower frame pipes. A pipe fence configured, wherein the vertical pipe is provided with a connecting member at an end of the pipe, and the connecting member is loosely inserted into openings provided at predetermined intervals on the pipe walls of the upper and lower frame pipes. together, the upper and lower frame pipe is retained by a retaining member provided separately, Ri Na is connected to the upper and lower frame pipe connecting member, the size may be inserted into the vertical pipe of the bar A groove for engaging the retaining member is formed on the outer periphery of the substantially central portion of the bar in the axial direction, and the retaining member is made of a disk-shaped flexible material having a through hole in the center. Engaged with the wall of the opening of the upper and lower frame pipes on the outer peripheral surface That the groove is formed, is shall protrusions such formed that the groove and the engagement of the connecting member to the inner peripheral surface of the through hole.
[0010]
In the above configuration, the left and right frame pipes in the configuration of claim 1 are configured as vertical pipes at the left and right ends, and are configured to be mounted with metal fittings interposed between support columns in which the upper and lower frame pipes are erected, Even if comprised in this way, the effect similar to the said Claim 1 is acquired. That is, the upper and lower frame pipes and vertical pipes are loosely inserted into the openings provided at predetermined intervals on the pipe walls of the upper and lower frame pipes, while the upper and lower frame pipes are connected to the upper and lower frame pipes. Since it is connected to the frame pipe by a retaining member provided separately, it is connected to the sloping ground with a slope of 10% or more from the flat ground within the range of play of the connecting member loosely inserted in the opening. In addition, the connection part has no protrusions such as bolts and nuts and has a good appearance.
[0011]
