Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tool used in high jump and pole vault competitions, and more particularly to a support tool for the pole thereof. This kind of equipment is used for a limited number of people in a formal stadium,
It is roughly divided into those for facilities that are handled only by qualified persons, and those for education at schools and general playgrounds, and those used by many people for civic sports. It has been improved to suit.

"Prior Art" As shown in FIG. 1, a typical example of a conventional product is that a base 1 is planted on a pedestal 1, a scale display 6 is provided on the base, and a long groove 7 for a handle screw is provided. Planted Paul 3,
A bar 5 is attached to a support tool 4 slidably provided on the pole 3.
And slide the support 4 up and down to raise and lower the bar, and fix the support with the handle screw at the desired position in the long groove of the pole, and also fix the base with the handle screw 8 provided on the pedestal. It was something to do.

Therefore, in order to stabilize the bar placed on the support, it is important to eliminate the swing of the pole, and for that purpose, it is important to fasten the base pillar to the pedestal quickly. However, in most conventional products, the screw is used for the handle, so it is not possible to completely prevent the so-called "glazing" because it is fixed at a point, and the latter is used by many people. However, because the handle screw has a so-called rattling that makes it difficult to fix, and the pole thickness is increased to prevent it, the tool itself becomes heavy overall, small, Junior high school students had drawbacks such as being difficult to handle.

"Means for solving the problems" The present invention was devised with the above points in mind. The base pillar of the conventional product was removed, and the base pillar and the handle screw provided on the base were Combine the functions to form a pole support,
The support is integrally attached to the pedestal, and the pole is made of an extruded material by arranging a reinforcing column in the center so that the pole has sufficient strength even if it is thin, and the support is fastened to the pole. It is intended to eliminate the drawbacks of the conventional product by changing the conventional point fixing method to the surface fixing method by fixing the two side pieces of the symmetrical two pieces together. And a notch is provided on the upper side of one side, and the protruding piece of the fastening piece is inserted into the long hole provided on the free side of the upper side of the notch, and the lever having the protruding portion is attached to the protruding piece. An attempt is made to integrally attach a pole support tool for fixing a planted pole to a pedestal by pivotally rotatably pivoting and reducing the space between the separated sides by vertical movement of the lever. It is a thing.

[Embodiment] The configuration of the present invention will be described in detail based on an embodiment shown in the drawings.

The present invention comprises two main members, a pole support A shown in FIG. 3 and a fastening tool B shown in FIG. The pole support A is formed of two semi-circular 15,16 symmetrical pieces, and the both side pieces have lateral sides 18, 19, 24, 2 at both left and right ends.
5 has a fixing piece 20,26 through which holes 21,27 for fixing to the pedestal facing outward are provided at the lower end of each side edge, and the upper part of one side edge 19,25 Long holes 23 and 29 for inserting the projecting piece 32 of the tightening tool 13 are provided through the hole, and extend from below the long hole to below the projections 22 and 28 provided so as to project to the inner surface of the piece. Horizontal notches 17 and 30 having an appropriate length are provided.

The fastening tool B has a fastening piece 33 having a projection 32 through which a hole 31 for pivotally mounting a lever 36 is provided, and a lever 36 having a projection 34 through which a hole 35 corresponding to the hole 31 is provided. Is formed by.

The pole 37 used in the present invention is approximately 20% thinner than the conventional product and is made of aluminum extruded material and has a substantially circular shape, and is a display scale for reading the height of the bar mounted on the bar support. And a scale groove 38 for fitting and adhering, and projections 22 and 28 provided on the pieces 15 and 16 of the support A on the opposite side of the groove.
And a reinforcing column 40 is provided so as to be installed in the scale groove 38 and the groove 39.

Next, the assembly and the attachment to the pedestal will be described based on FIG. 6, and the pedestal 13 having the holes 14 matching the holes 21 and 27 of the fixing piece, and the hole 12 matching the hole of the fixing piece and the hole 14.
And a pedestal 11 having a substantially T-shape so that the holes are aligned with each other, and the side edges provided with the long holes 23 and 29 above the notches 17 and 30 are separated from the side edges 18 and 18. 24, the support A having the side edges 19 and 25 integrally fixed thereto is mounted on the pedestal 13, and the support A pedestal 11 and the pedestal 13 are integrally attached.

To attach the fastening tool B to the support tool, the projecting piece 32 is attached to the long holes 29 and 23.
Align the through hole 31 with the hole 35 and tighten the lever 36 with a pin.
By pivoting to 33.

[Advantages of the Invention] Since the present invention has the structure as described above, it is firmly and integrally attached to the pedestal formed in a substantially T shape by the fixing pieces provided on the outer sides of the lower sides of both sides. Therefore, the support is stable and there is no so-called “grat”. In addition, the two pieces forming the support are integrally fixed to each other by the side surfaces, so that the fixing strength is strong, and a notch is provided on the upper side of one side, so that the upper side is By separating the loosened side and rotating the fastener lever provided on the side in the direction of the arrow in FIG. Since it is fixed on the entire inner peripheral wall surface, the stability is increased compared to the point fixing of the conventional product, and it has a great effect in preventing the deflection of the pole. Furthermore, since the projections provided on the inner surfaces of the individual pieces are fitted into the grooves of the poles, the poles do not rotate freely.

As described above, since the high jump tool according to the present invention can fix and release the pole only by operating the lever,
Even elementary and junior high school students can do it easily and quickly, so it is ideal for use by many people. Furthermore,
Since the pole itself is thinner than the conventional product for fixing the surface and it can be used even if it is made of extruded aluminum, it is possible to provide light and inexpensive tools, which has a great effect on the site of school education It is a thing.
