Description

[Detailed explanation of the invention] This invention is a support fixing device used to set up a net for badminton games, and its purpose is to fix the support in places equipped with floor metal fittings (such as gymnasiums). In addition, we would like to provide a movable column fixing device that can be easily fixed in any location and that allows the weight used for fixing to be transported and moved very easily. It is something to do.

This type of badminton support is generally fixed under the floor of a gymnasium with concrete or the like, and the support is fixed by inserting the support into a tool.

Therefore, such a prop holder may be used in a place that is equipped with the equipment, but in a place where the prop holder is not equipped with the equipment, the prop cannot be erected and fixed, and the competition cannot be held.

Therefore, the inventor of the present invention developed a mechanism for fixing the above-mentioned prop support with a weight so that the prop can be fixed even in places without tools (Utility Application No. 52-158608). In this case, in consideration of transportation of the weights, a plurality of weights of a weight that can be carried are stacked on top of each other.

However, the method of stacking a plurality of weights weighing 15 to 20 kg required work to be done on the mating surfaces, etc. when forming the weights, which required a lot of work.

Therefore, the present invention improves the molding and transportability of such a weight.The weight is made into a single piece, wheels for traveling are attached to it, and a steady rest is constructed across the weight and the support. The rod can be used as a handle rod when transporting a weight.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
1 is plywood, 2 is a column, 3 is an arm tube, 4 is a weight, and 6 is a steady rest/handle rod.The base plate 1 is formed into a substantially trapezoidal planar shape using a flat metal plate. A rod is fixed in the center of the upper surface of the column holder in an upright position, and the column 2 is fitted onto the rod and tightened with a tightening bolt or the like, so that the column holder is fixed in an upright position in a removable manner. .

Further, a plurality of nuts 8 are fixed at intervals on the upper surface of the base plate 1 on the center line of the upright column 2, and the arm tube 3 is placed horizontally on the upper surface of the nut 8, and the bolt At 9, it is fixed integrally with the base plate 1.

The arm tube 3 is a hollow tube with a length that projects outwardly from the base plate 1, and a weight 4 is integrally fixed to the upper side end of the arm tube 3 that protrudes from the base plate 1. The pillar 2 can be prevented from collapsing under the weight of the net.

The weight of the weight 4 is selected relative to the length of the arm tube 3.

That is, if the length of the arm tube 3 is short, the weight of the weight 4 will naturally increase, and if the length of the arm tube 3 is long, the weight of the weight will be lighter.
It is not possible to make the arm tube 3 unnecessarily long in relation to the referee stand etc. installed on the side of the support 2, and from this perspective, it is preferable that the length of the arm tube 3 is about 60 cm and the weight of the weight 4 is about 60 kg. .

The weight is formed into a rectangular shape, and wheel mounting portions 10 are recessed on both sides opposite to the side to which the arm tube 3 is attached, and the wheels 5 are rotatably mounted in the wheel mounting portions 10. There are bolts 1 at each side end to prevent the axle 5' from coming off.
1 is screwed.

Further, when mounted on a vehicle, the lower surface thereof is installed so as to protrude downward from the lower surface of the weight 4.

Further, on both sides of the lower surface of the weight 4, there is provided a pedestal 12 that abuts against the floor surface a and is adjustable up and down.

Insertion holes 1 are provided on both sides of the upper surface of the weight 4 formed as described above.
3 is bored, and one side 6-1 of the steady rest/bundle rod 6
The bolt 14 can be inserted into the side and tightened and fixed, and the other side 6- of the steady rest/bundle rod 6
2 is engaged with a hook piece 7 which is attached to the support column 2 so that the vertical sliding tool can be fixed thereto, thereby preventing the support support 2 from being bent.

The steady rest/bundle rod 6 is formed into a front road shape and is bent into a substantially - shape on the side, with one vertical side portion 6-1 facing the weight 4 side.
The other inclined side portion 6-2 is attached to the support column 2 side.

Further, the steady rest/bundle rod 6 is used as a hand bundle when transporting the weight 4, but in this case, the bundle rod 6 is removed from the support 2 and the weight 4,
Change the orientation so that the other inclined side 6-2 of the bundle rod 6 is located on the side opposite to the arm tube 3, and insert and fix it.
The weight 4 can be moved by the wheels 5 by pushing down the other side 6-2 of the steady rest/bundle rod 6 and pulling up the tip side of the arm tube 3 attached to the weight 4.

In the figure, reference numeral 15 denotes a latch, which is latched to a floor metal fitting that is attached to the floor surface, so that the base plate 1 can be integrally connected to the floor surface. 3 becomes unnecessary.

Further, 16 is a cover formed of a rubber plate, which is placed over the base plate 1 to prevent scratches on the floor surface, and also has an anti-slip effect to prevent the base plate 1 from sliding. cover 2
4 has a form that is removable from the base plate 1.

Since the present invention is constructed as described above, the support can be erected and fixed not only in a place where a support is provided with a tool, but also in a place where a support is not provided.

In addition, the weight used for raising and fixing the column can be easily and safely transported by removing the steady rest/bundle rod that is attached between the weight and the column and using it as a bundle. It is portable and very convenient.

Therefore, the usability of the movable column fixing device can be improved.
