Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a tool for a high jump or pole vault competition, and more particularly to a support for placing a bar at a desired position. There are two types of equipment, one for facilities used only for athletes limited to formal stadiums, and one for schools and general stadiums used by many people for education and civil sports. Apart from this, the invention has been designed to be suitable for the latter. 2. Description of the Related Art A typical conventional product of the above-mentioned type is a pole on which a height scale is displayed is erected on a pedestal, and a bar is placed on a support slidably provided on the pole, and Is slid up and down to adjust the height, and is tightened and fixed at a desired position with a handle with a handle screw. Since this method is fixed at points, a so-called "glare" has occurred.
Therefore, the present inventors devised Japanese Utility Model Publication No. 6-7725 in order to solve these problems. However, even if the invented product is used for a long period of time, it cannot be completely prevented, and the so-called "glare" has occurred to some extent. SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has been devised by a conventional locking means for a bar mounting support slidably provided on a pole. ,
It is intended to solve the problem of so-called "grazing". Specifically, the principle of the wedge is adopted for the locking means, and a more complete fixing state is obtained in a simple manner. [0004] A high jump competition support device according to the present invention comprises: a support portion having a flat bar mounting table on an upper surface on one side of a main body mounted on a pole so as to be vertically movable; On the side symmetrical to the support portion, one surface has a slope, the upper surface has a spike, and a locking portion connected to an operation button described later by a pin is provided. An operation button having a slope facing the slope of the locking portion, having a long hole penetrating in a position parallel to the slope, and having a half hole for fitting the sprung inside the eaves above the slope. It is a means to solve the problem. According to the present invention, there is provided a support for a high jump competition having the above-described structure. When an operation button is pressed, a spring provided on an eave on an upper slope is compressed and descends. So, the locking fixture that was locked and fixed with the pole until then,
The locking portion serving as a wedge is in a state where it is removed, and is released from the fixed state to be in a free state. Then, the locking device is moved to a desired position, and then, when the operator releases the hand pressing the operation button, the operation button is pushed up by the repulsive force of the hitherto compressed spring, and the operation button is moved to the fixed position. It becomes a state where a wedge is driven in, and instantaneously maintains a fixed state on the spot. At this time, the button and the locking portion are connected by a penetrated pin. However, since a long hole is provided in parallel with the slope of the button, the pin position in the long hole can be changed. In addition, the up and down operation can be performed without hindrance without impairing the connection state, and can be made simple and repeatable. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 illustrates a state in which a high-flying sports support according to the present invention is mounted and fixed on a pole on a pole, and FIG. 2 shows only a locking and fixing part of FIG. 1, particularly a main part of the present invention. Is partially cut away, and FIG. 3 is an explanatory view of an operation button which plays an important role in the locking and fixing portion.
FIG. 4 shows a state of the main member when the product of the present invention is fixed to the pole, and FIG. 5 shows a state of the main member when the product is released from the fixed state of FIG. It is. The support device for high-flying sports according to the present invention has a substantially circular main body 2 into which a pole is inserted, and a flat bar mounting table 3 on one side of the main body. 4, and on the symmetrical side of the support portion, one surface has a slope,
On a planar upper surface, there is provided a locking portion 5 provided with a ridge 10. The locking portion has a slope facing the slope, and has a long hole 9 penetrating in a position parallel to the slope. At the same time, an operation button 7 having a half hole 11 for fitting the spline is provided in the locking portion 5 in the eave portion above the slope. The operation button 7 and the locking portion 5 are connected by a pin 6 inserted into a long hole 9 of the operation button, and the operation button is vertically movable within the range of the long hole. In FIG. 4 in which the product of the present invention is locked and fixed to the pole 1, the operation button 7 is always pushed upward by the repulsive force of the ridge 10 provided on the upper surface of the locking portion 5. . Therefore, the joint surface A between the slope of the operation button 7 and the slope of the locking portion 5 is strongly adhered, and the locking portion 5 serves as a wedge. Reference numeral 8 in the drawing denotes a rubber body attached to the joint surface of the operation button in order to further secure the locked state at the joint surface B between the product of the present invention and the pole. In order to move the product of the present invention to a desired position, the locked state of FIG. 4 is released. In FIG. 5, when the operating button is pressed downward, the button starts to descend while compressing the firing. The position of the pin 6 in the elongated hole 9 penetrated in parallel with the slope is located at the upper part of the hole, and the joint surface A between the slope of the operation button 7 and the slope of the locking portion 5 is formed. And the joint surface B between the operating button 7 and the pole 1 simultaneously releases the fixed state, and the product of the present invention can move up and down. In particular, at this time, the release of the fixed state of the joint surface A between the locking portion and the operation button means that the driven wedge is removed, so that there is no factor that hinders the vertical movement, and the simple operation is performed. And no extra force is required. Further, if the user moves the button to the desired position and releases the operation button pressed downward, the operation button is instantly pushed up by the repulsive force of the firing, and returns to the state of FIG. It will be done firmly. According to the present invention, there is provided a support for a high jump competition, comprising a support having a flat bar mounting table on one side of a main body mounted on a pole so as to be vertically movable; On the side symmetrical to the portion, one surface presents a slope, and on the upper surface, there is provided a locking portion having a spike. The locking portion has a slope facing the slope, and a position parallel to the slope. And an operation button having a half hole for fitting the spline is provided in the eaves above the slope. Therefore, at the time of fixing, the locking portion plays the role of a wedge, and the fixing is not only firm, but also the operation of moving to the desired position can be performed only by pressing the operation button downward. Can be canceled, so that the operation is easy. Furthermore, at the time of re-fixing, if you release your lowering hand, the wedge will be driven instantly by the action of the firing, so that a large number of competitors and students will use one after another in general stadiums and schools It can be said that it is the most suitable tool in the field.
