Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: When constructing a frame of a playground equipment or the like with pipes, rods, etc., a method of fixing metal fittings with rivets is generally used as a joint. However, in that case, there are the following problems. B, Insufficient strength and durability of rivets. B. The metal fittings are displaced during construction, which delays the work and makes the appearance after construction poor. The present invention aims to remedy the aforementioned drawbacks. SOLUTION: The hook type connection fitting of the present invention has an inner surface 2,
As shown in the figure, a hook 4 is provided on a part of the inner surface of a contact plate 1 shaped to match the outer surface of an adherend 11, and a cylindrical mounting seat 5 with a bottom 6 or a bottom is provided on the outer surface of the plate. Is provided, and fixing screw seats 7 and 8 are provided on each part of the mounting seat and the contact plate. To use this, the contact plate 1 of the connecting fitting is attached to the outer surface of the adherend 11. When the hook 4 is applied, and the hook 4 is inserted into the hooking hole 12 of the adherend that has been pre-squeezed and lowered slightly, the mounting seat 5 is joined to the adherend 11 in a suspended state. Next, when a screw is driven into each mounting hole 8 of the contact plate and the adherend, the joint portion is tightened.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a pipe fitting, and more particularly to a connecting fitting used as a joint for connecting pipes such as a play equipment frame and bars.

[0002]

[Prior art]

 When constructing a frame for playground equipment, such as pipes and bars, a method of fixing metal fittings by rivets is generally used as a joint.

[0003]

[Problems to be solved by the invention]

 However, in that case, there are the following problems. B, Insufficient strength and durability of rivets. B. The metal fittings are displaced during construction, which delays the work and makes the appearance after construction poor.

[0004]

[Means for Solving the Problems]

 The hook-type connecting fitting of the present invention is provided with a hook 4 on a part of the inner surface of an abutting plate 1 having an inner surface 2 which fits the outer surface of an adherend 11 as shown in the drawing, and the outer surface of the plate. A cylindrical mounting seat 5 with or without a bottom 6 is provided on the surface, and fixing screw receiving seats 7 and 8 are provided on each of the mounting seat and the corresponding plate.

In the figure, 11 is an adherend (thick pipe), 12 is a hook hole formed in a part of the adherend, and 13 is an attachment (thin pipe).

[0006]

[Action]

 The operation of the connection fitting of the present invention will be described in the case of using a thick pipe as the adherend 11 and connecting the thin pipe mounting body 13 to the outer surface thereof.

As shown in FIG. 2 (A), the contact plate 1 of the connecting metal fitting is applied to the outer surface of the adherend 11, and the hook 4 is inserted into the hook hole 12 of the adherend that has been pre-cleaved. When it is lowered a little, the mounting seat 5 is hung and joined to the adherend 11. Next, when a screw is driven into each mounting hole 8 of the contact plate and the adherend, the joint portion is tightened.

[0008]

[Embodiment]

 As the mounting seat 5, in addition to the cylindrical one as shown in FIG. 2 (A1), there is one having a lateral bottom 6 as shown in FIG. 3 (B) (C), etc., which are appropriately selected and used. As shown in FIG. 1, the thin pipe (attachment body 13) is connected to the thick pipe (adherend 11) in a crossover manner, a half crossover manner, a cheese manner, or the like.

Further, by changing the forms of the adherend 11 and the attachment body 13, it is possible to construct a complicated shape having various angles, and if the adherend is pre-screwed and a series of hook holes are formed, Workability is improved by using one of them in the field. In this case, it is advisable to insert a blind plug into the unused hole to prevent mischief.

[0010]

[Effect of the invention]

 According to the present invention, since the rivet can be inserted and tightened with respect to the screw seat 8 in a state in which the contact plate 1 is hung on the adherend 11, the work is easy and the work is easy during the construction. At the same time, the strength of the rivet mounting part is also increased. (B) If the hanging holes 12 of the adherend are opened before carrying on the site or at the beginning of construction, the labor on site can be further reduced. By changing a part of the mounting seat 5 to the contact plate 1, the mounting direction, etc., crossover, half crossover, cheese and various other types of mounting can be performed, and complicated play equipment frame assembly and work site Construction can be performed quickly and accurately.
