Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention mainly relates to a horizontal bar mounting bracket for a horizontal gymnastics bar installed outdoors in a park or the like.

(Prior art) Conventional horizontal bar mounting brackets for this type of gymnastics horizontal bar are usually just a horizontal cylinder part for inserting the horizontal bar attached to the main body wall of the cap that fits over the upper end of the column. It was not easy to attach the iron bar to the support without shaking, and it also lacked durability.

(Purpose of the invention) The present invention aims to solve the above-mentioned drawbacks and provide a horizontal bar mounting bracket for a gymnastics horizontal bar that does not cause rattling and allows comfortable horizontal bar exercise over a long period of time. be.

(Structure of the invention) The present invention consists of an upper reinforcing rib and a lower side in which a horizontal cylinder part for inserting an iron bar that communicates with the main part of the cap is formed on the body wall of the main body of the cast iron cap that can be fitted onto the upper end of the support column. A series of cuts are provided extending integrally with the reinforcing ribs and extending from the lower end of the cap main body through the lower reinforcing ribs to the open end of the horizontal cylinder part, and each of the cap main body and the horizontal cylinder part The wall is characterized by having opposing bolt insertion holes and bolt insertion holes, respectively.

(Example) Next, the present invention will be explained in detail with reference to illustrated examples.

Reference numeral 1 denotes a cast iron cap main body that can be fitted onto the upper end of the support column, and on the body wall of the cap main body 1, a horizontal cylinder part 2 for inserting an iron bar that communicates with the cap main body 1 has an upper reinforcing rib formed above and below the horizontal cylinder part 2. 2a and the lower reinforcing rib 2b are both integrally stretched. Reference numeral 3 indicates a series of cuts provided from the lower end of the cap main body 1 through the lower reinforcing rib 2b to reach the opening end of the horizontal tube portion 2; Bolt insertion holes 5, 5 are provided in two stages, upper and lower, facing the body wall of 1, and 5 are bolt insertion holes similarly provided in the body wall of the horizontal cylindrical portion 2 in a direction perpendicular to the cut 3.

This structure includes a cast iron cap main body 1 that can be fitted onto the upper end of a support column, and an iron bar that is fitted onto the upper end of a support support 11 of a horizontal gymnastics bar and is stretched over the body wall of the cap main body 1. Insert the end of the iron rod 12 into the horizontal cylinder part 2 for insertion, and insert the bolt 13 into the opposing bolt insertion holes 4, 4 provided in the body wall of the cap main body 1 and the bolt insertion holes 14, 14 of the support column 11. At the same time, tighten the nuts 15 and fix the bolts 16 between the bolt insertion holes 5, 5 of the horizontal tube part 2 and the iron rod 12.
Even if the main body 1 of the cap is made of cast iron, by inserting it into the bolt insertion hole 17 provided in the hole 17 and tightening it with the nut 18, the cap main body 1 reaches the open end of the horizontal tube part 2 through the lower reinforcing rib 2b from its lower end. A series of cuts 3 are provided so that the bolts 13, 16 and the nut 1
5 and 18, the series of cuts 3 is narrowed, and the narrowing of the cuts 3 provided on the lower reinforcing rib 2b allows the cap main body 1 and the horizontal tube part 2 to communicate with each other. As a result, the holding force of the cap main body 1 holding the support column 11 and the horizontal cylinder part 2 holding the end of the iron rod 12 is not strained, so that the iron rod 12 after tightening is stable. Therefore, it is firmly attached to the support column 11, and there is no risk of it shaking or rotating. Moreover, upper reinforcing ribs 2a are provided on the upper and lower sides.
The horizontal cylindrical part 2 for inserting the iron bar, which is formed with a lower reinforcing rib 2b and integrated with the cap main body 1, can withstand the large load associated with intense movement of the iron rod.
Coupled with the fact that it is entirely made of cast iron, it allows for comfortable horizontal bar movement over a long period of time.

(Effects of the invention) As is clear from the description of the above embodiments, the present invention is a horizontal bar mounting bracket for a gymnastics horizontal bar that solves the drawbacks of conventional horizontal bar mounting brackets and allows stable and comfortable horizontal bar exercise at all times. It has extremely great practical value.
