Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a universal joint for a fence, which is used for a connection part of a fence and allows the angle of the connection part to be freely adjusted.

[Prior Art and Problems to be Solved] Conventionally, when connecting the connecting parts of fences in an adjustable angle manner, a universal joint for each fence separately connects the upper and lower beams of the fences to be connected. I was trying to connect using .

However, in the case of such conventional universal joints for fences, the upper crosspiece of the fence to be connected,
Since the lower crosspieces were connected separately, the upper and lower crosspieces were not connected at the connecting part, resulting in a disadvantage that the strength of the connecting part was low.

In addition, since the upper and lower fence universal joints rotate separately, there is a drawback that distortion occurs due to rotation errors in the upper and lower connecting parts.

Furthermore, when the upper and lower crosspieces are connected separately using the upper and lower universal joints for fences, there is a drawback that there is no crosspiece between the upper and lower universal joints for fences, resulting in irregular gaps in the connecting portion.

[Means for solving problems] The present invention has been made to solve the above-mentioned problems of the conventional art. A joint main body constituted by a member, and a rotary support portion that connects both the vertically long members so as to be horizontally rotatable about the longitudinal direction, projecting laterally above and below the both vertically long members to the side of the fence. It is configured to include a horizontal bar fixing portion that is fixed to the bar.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

1 to 4 are diagrams showing an embodiment of the present invention.

In the figure, 1 is a fence, and 2 is a universal joint for the fence.

The fence 1 is an integral structure in which a large number of vertical bars 5 are attached between an upper bar 3 and a lower bar 4 as horizontal bars. The upper rail 3, the lower rail 4, and the vertical rail 5 are each made of extruded material.

The fence universal joint 2 connects both the left and right fences 1 and makes the angle of the connection part adjustable, and includes a joint body 6, a rotation support part 7, and a horizontal beam fixing part 8. . These joint main body 6, rotation support part 7, horizontal beam fixing part 8, etc. are formed of extruded material as in the case of fence 1.

The joint body 6 is constituted by a pair of left and right vertically elongated members 9 and 10. The longitudinal members 9 and 10 are formed as cylindrical members with a cross-sectional shape that forms a substantially quarter circle in the assembled state. Furthermore, caps 11 and 12 are attached to both ends of the longitudinal members 9 and 10. These caps 11 and 12 have protruding fitting pieces 11a and 12a attached to the longitudinal members 9 and 1.
It is designed to be inserted and fitted into the openings at both ends of 0 and fixed.

The rotation support part 7 connects both vertically long members 9 and 10 so as to be horizontally rotatable around the longitudinal direction (vertical direction in the figure), and connects two connecting pieces 1 from one vertically long member 9.
3 and 13 are formed by notches, and a recess 14 is formed between these connecting pieces 13 and 13,
The other longitudinal member 10 is formed with a connecting piece 15 that engages in the recess 14 at a position corresponding to the recess 14 . An insertion hole 17 for a connecting pin 16 is formed in the connecting pieces 13 and 15 in the axial direction. Then, with the connecting pieces 13 and 15 combined, the connecting pin 16 is inserted into the insertion hole 17, and the connecting pieces 13 and 1
5 are rotatably connected. Further, the rotation support portions 7 are provided at two locations on the upper and lower sides of the vertically elongated members 9 and 10, so that they can be rotated without distortion and are also robust.

The horizontal beam fixing part 8 connects and fixes each vertically long member 9, 10 and the fence 1, and both vertically long members 9,
They are located above and below 10. That is, the vertical members 9 at positions corresponding to the upper and lower bars 3 and 4 of the fence 1 as horizontal bars,
It is attached and fixed to the side surface of 10 with a screw 18 in a state in which it protrudes laterally. Further, this horizontal bar fixing portion 8 is formed in a size that can fit into the end openings of the upper and lower bars 3, 4, and the side surface of the horizontal bar fixing portion 8 is
A screw hole 19 is formed for fixing to.

Then, insert the horizontal bar fixing part 8 into the ends of the upper and lower bars 3 and 4 of the fence 1, and insert the screw 20 from the outside through the holes of the upper and lower bars 3 and 4 into the screw holes 19 of the horizontal bar fixing part 8.
By screwing together and tightening and fixing, the fence 1 can be easily connected.

In addition, 21 in the figure is a support for erecting the fence 1.

[Effects of the invention] As explained above, in the universal joint for fences of the invention, the joint main body is composed of a pair of left and right vertically long members, and these vertically long members are horizontally rotatably connected by a rotation support part. At the same time, since we have decided to provide horizontal bar fixing parts that are fixed to the horizontal bars of the fence at the top and bottom of both vertically elongated members, the upper and lower bars, which are the horizontal bars of the fence, can be integrally connected by the joint body, increasing the strength of the fence connecting part. It has the effect of being able to

Further, since the joint body is simultaneously rotated up and down via the rotation support portion, it is possible to prevent distortion due to an error in the vertical rotation of the fence connection portion.

Furthermore, since the joint body is present over the entire longitudinal direction of the connecting portion, it is possible to prevent gaps from forming in the connecting portion as in the conventional case, and there is an effect that the appearance can be improved.
