Description

[Detailed description of the invention] [Technical field of the invention] The present invention relates to a horizontal bar device installed indoors, etc.
In particular, the present invention relates to an improvement in a support structure for horizontally attaching a bar member to a column.

[Prior art]

BACKGROUND ART Various types of iron bars used as equipment for gymnastics have been proposed and put into practical use.

Figures 1 and 2 show this kind of conventional iron rod device, in which 1 and 2 are square pipe-shaped supports vertically installed on the floor 3 with a desired distance between them, and 4 is a space between the above-mentioned supports 1 and 2. The bar member 4 is a bar member that is horizontally hung horizontally, and both ends of the bar member 4 are connected to the pillars 1 and 2 by support fittings 5 and 6 and connecting pins 7 and 8.

As shown in FIG. 2, the support fittings 5 and 6 include a U-shaped portion 9 that is fitted from the side to the support columns 1 and 2, and a bar member that protrudes from the center of the base of this U-shaped portion 9. The U-shaped portion 9 has an elongated hole 11 through which the connecting pin 7 or 8 is inserted. In addition, a plurality of mounting holes 12 and 13 for adjusting the height of the bar member 4 are bored in the pillars 1 and 2 at equal intervals in the length direction of the bar member 4. The connecting pins 7 and 8 are inserted through the respective connecting pins 7 and 8.

In the iron bar device having the above configuration, when horizontally fixing the bar member 4 between the supports 1 and 2, first fit the fitting parts 10 of the support fittings 5 and 6 to both ends of the bar member 4, and then tighten the screws 14. The support fittings 5 and 6 are fixed to the bar member 4 by tightening. After that, support metal fittings 5, 6
The U-shaped portion 9 of the U-shaped portion 9 is engaged with the columns 1 and 2 from the side, and the elongated hole 11 of the U-shaped portion 9 is inserted into any one of the columns 1 and 2.
After matching the two mounting holes 12 and 13, the connecting pins 7 and 8 are respectively inserted into the matching holes, whereby the bar member 4 is horizontally fixed between the supports 1 and 2.

In addition, when adjusting the height of the bar member 4, pull out the connecting pins 7, 8, move the bar member 4 up and down while keeping the support fittings 5, 6 engaged with the columns 1, 2, and adjust the height of the bar member 4. When the desired height is reached, the connecting pins 7 and 8 can be inserted into the elongated hole 11 and the mounting holes 12 and 13, respectively.

However, when adjusting the height of the bar member 4, since the U-shaped portions 9 of the support fittings 5, 6 remain engaged with the columns 1, 2, the support fittings 5, 6
In order to slide the bar member 4 relatively smoothly along the length direction, a certain amount of clearance d must be created between the inner surface of the U-shaped portion 9 and the outer peripheral surfaces of the columns 1 and 2. No. If this is not done, the support and the U-shaped portion 9 will bite into each other, making it impossible to move the bar member 4 up and down.

However, creating the gap d between the U-shaped portion 9 of the support fittings 5, 6 and the pillars 1, 2 as in the above conventional method is convenient for vertical movement of the bar member 4; When performing gymnastics using
The rattling between the support fittings 5, 6 and the pillars 1, 2 causes noise, gives discomfort and anxiety to the person using the iron bar, and has the disadvantage that the bar member 4 rattles.

[Summary of the idea]

The present invention solves the above-mentioned conventional drawbacks, and includes a plate-shaped support clamping member inside the U-shaped part of the support fitting that engages with the support from the side and is connected to the support by a connecting pin. This column tightening member is arranged parallel to the side surface, and is supported by a plurality of guide rods in the U-shaped portion so as to be movable in the direction of coming into contact with and away from the side surface of the column. By rotatably connecting the threaded end to the above-mentioned column clamping member, and tightening this threaded rod to press the clamping member against the column, the support fitting is fixed to the column without play, thereby stabilizing the bar member. The object of the present invention is to provide a horizontal bar device that enables reliable support.
