Abstract

(57) [Summary] (Corrected) [Purpose] A part that connects structural pipes of garden houses and columns such as vegetables. Anyone can easily and firmly connect with opponents of different diameters at any angle in a short time. it can. [Structure] Two holding claws 3 are opposed to each other on the outer periphery of a disk-shaped base provided with a clip 1, and a groove and a projection 5 are provided in an intermediate portion on the bottom surface of the base. Two pieces are used as one set. Since the grooves and the protrusions 5 rotate concentrically, the toes 6
There is no danger of it coming off. When disassembling, push both claws apart. The inner diameter of the clip should be slightly smaller than that of the pipe or column. The opening of the clip is a twisted portion that is narrower than the inner diameter, and the tip is widened in a taper shape. If the lower end of the holding claw 3 is extended and bent to form an L-shape, it is easy to disassemble.
When the holding claw 3 has a thin portion, it is possible to increase the bending when combining or disassembling. If the corners of the inner corners of the holding claws 3 and the base are rounded, it is hard to break. When the holding claws 3 and the protrusions 5 are made radial, the blind spot becomes small.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structural pipe for a horticultural house and a part for connecting pillars such as vegetables by crossing them.

[0002]

[Prior art]

 In general, the structural pipes of garden houses used joints made of metal or plastic, but it was difficult to connect them to other than the same diameter, such as at a fixed angle.

The pillars of vegetables and the like were bound by strings and wires, but some experience and time were required.

[0004]

[Problems to be solved by the device]

 The structure of a gardening house is to firmly connect the pipes and columns of vegetables and the like to anyone with a different diameter at an arbitrary angle without taking time easily.

[0005]

[Means for Solving the Problems]

 The invention will be described with reference to the drawings. Two holding claws (3) are provided on the outer periphery of a disk-shaped base (2) having a clip (1) for holding a pipe or a column, and the inside of the claw (3) is In the middle of the bottom surface of the base (2), an arcuate groove (4) and a protrusion (5) with an angle deviated from the holding claw (3) by about 90 ° are provided, and some elastic material such as plastic is used. Mold.

[0006]

[Action]

 The two cross joints of the present invention are used as one set by combining them, but when selecting mating partners of arbitrary diameters and pushing the grooves (4) and the protrusions (5) together, the holding claws (3) of each are held. Hold the outer circumference of the opponent's base (2) slightly open, push it further and pass through the toe (6), the holding claws (3) will close and the bottom surfaces of them will adhere to each other.

[0007] The pipe or the column is firmly held by its strong elasticity simply by pushing it into the clip (1) having the diameter.

The combined cross joints are rotatable with respect to each other and can be set at an arbitrary angle, and since they are rotated concentrically by the mutual groove (4) and protrusion (5), the toes (6) of the other end There is no risk of it coming off the outer circumference of the base (2).

In the case of disassembling, when the holding claws (3) of both sides are sequentially pushed open, the toes (6) are disengaged from the outer periphery of the base (2) of the partner.

[0010]

【Example】

 The inner diameter of the clip (1) can be adapted to the standard of pipes and stanchions of, for example, φ8 to φ21, but it is preferable to make it slightly narrower to have a stronger holding force.

The opening of the clip (1) is provided with, for example, a twisted portion narrower than the inner diameter to hold a pipe or a supporting column, and if the opening is tapered toward the tip, the pipe or the supporting column can be easily pushed. be able to.

Before the combination, one cross joint may be pushed into one or both pipes and columns, and then combined with the mating cross joint.

The lower end (9) of the holding claw (3) can be easily assembled by forming a taper inclined inward.

When the lower end (9) of the holding claw (3) is extended and bent to form an L-shape, it is easy to push with two fingers of both hands when disassembling, and at the same time, the four toes (6) can be removed. .

If the holding claw (3) has a slightly thin portion in the circumferential direction of the base (2), the bending when combining or disassembling becomes great, and even if the toe (6) is made large, it is small. It can be decomposed under pressure.

In order to prevent the base of the holding claw (3) from cracking, the corner (7) of the inner angle with the base (2) is rounded and the outer peripheral upper edge (8) of the opposite base (2) is ), It is advisable to add a roundness for the thread chamfering degree.

If both lateral surfaces of the holding claw (3) and the protrusion (5) are made radially with the center portion narrowed, the dead angle when contacting each surface of the other side becomes small, and any practically necessary There is no problem in setting the angle of.

[0018]

【effect】

 According to this invention, anyone can easily connect the structural pipes of the gardening house and the columns of vegetables and the like to a partner having a different diameter at an arbitrary angle without spending time.
