BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting a goal for a game such as a soccer goal in which a crossbar is connected between left and right goal posts, and more particularly, to an embedded apparatus in which the lower end of a goal post is embedded in the ground. TECHNICAL FIELD The present invention relates to a mounting device capable of adjusting a height of a crossbar in a buried type competition goal which is inserted and supported in a pipe.

[0002]

2. Description of the Related Art There are generally two types of soccer goals: laying soccer goals and buried soccer goals. In an official game, it is necessary to use buried soccer goals with fixed goal positions. Have been.

[0003]

However, in a buried soccer goal, particularly in the case of a natural grass field,
If the soil becomes thinner, the grass grows, or the grass changes, the height of the crossbar with respect to the ground changes.

The height of the crossbar can be adjusted by adjusting the mounting position of the crossbar with respect to the fixed goal post. For this reason, in the configuration in which the height adjustment mechanism is provided on the ground portion, the height of the crossbar is reduced. In this case, it is not possible to satisfy the requirement that the form on the ground (the cross-sectional shape of the goal post and the crossbar) must not be changed.

SUMMARY OF THE INVENTION The present invention has been made in view of such conventional problems, and has an apparatus for mounting a goal for a game in which the height of a crossbar with respect to the ground is adjusted without changing the form of the ground. The purpose is to provide.

[0006]

The invention according to claim 1 is
A lower end of each goal post is fitted into a burial pipe fixedly buried in the ground with a competition goal having a pair of left and right parallel goal posts and a crossbar connected between the goal posts and extending in the left-right direction. By inserting and supporting, in the installation device of the goal for competition to be attached to the predetermined position,
A height adjusting mechanism for adjusting the height of the crossbar by adjusting the insertion depth of the lower end of the goal post into the buried pipe is provided inside the buried pipe.

According to a second aspect of the present invention, the height adjusting mechanism has a first stopper fixed to an inner peripheral wall of the buried pipe and an axial mounting position variably fixed to a lower end outer peripheral wall of a goal post. And a lower end surface of the second stopper abuts on an upper end surface of the first stopper by fitting the goal post into the buried pipe to support the goal post, and The height of the crossbar is adjusted by adjusting the mounting position of the second stopper to the goal post in the axial direction.

According to a third aspect of the present invention, the upper end surface of the first stopper and the lower end surface of the second stopper have the same inclination angle downward from the outside of the buried tube and the center of the goal post, respectively. It is characterized in that it is formed on an inclined tapered surface.

[0009]

According to the first aspect of the present invention, by adjusting the insertion depth of the lower end of the goal post into the buried pipe by the height adjusting mechanism, the height of the crossbar with respect to the ground becomes constant. In addition, since the height adjustment mechanism is provided inside the buried pipe in the ground, it is not necessary to change the form of the competition goal on the ground, and it is possible to satisfy the requirements required for soccer goals and the like. it can.

According to the second aspect of the present invention, the second stopper is received by the first stopper, thereby setting the axial mounting position of the second stopper on the goal post while supporting the goal post. The height of the crossbar integrated with the goal post can be easily and accurately adjusted because the height can be adjusted continuously within the range.

According to the third aspect of the present invention, by joining the first stopper and the second stopper with the tapered surface, a radial component force is generated, and the goal post is fixed to the stopper fixing side of the buried pipe. Because it is pressed against the inner wall on the opposite side, the goal post can be supported in a stable state without play.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall front view of a buried soccer goal attached by the attachment device according to the present invention, and FIG. 2 is an overall side view of the buried soccer goal (the buried portion is shown for clarity of the invention. It is shown enlarged.)

The buried soccer goal includes a pair of right and left parallel goal posts 2 and a cross bar 3 connected between upper ends of the goal posts 2 and extending in the left-right direction. The lower end of each goal post 2 is inserted and supported in a buried pipe 1 buried and fixed via a foundation 10. A front edge of a goal net 11 is connected to the pair of goal posts 2 and the crossbar 3 so that the goal net 11 is not loosened by the two wires 7 and the net stopper 9 tied to the wire stopper 8. It is stretched.

FIG. 3 shows a buried portion of a buried soccer goal, FIG. 4 is a sectional view taken along the line AA ′ of FIG. 3, and FIG.
It is BB 'sectional drawing of. Height adjustment for adjusting the height of the cross bar 3 together with the goal post 2 by adjusting the insertion depth of the lower end of the goal post 2 into the buried pipe 1 in the mounting device for a buried soccer goal having the above configuration. The mechanism is provided as follows.

That is, the innermost wall of the buried pipe 1 is made to protrude outward at the innermost wall side, the first stopper 5 is fitted into a concave portion 17 formed inside the buried pipe 1, and the back surface is provided with a plurality of bolts 12b. Fix with. On the other hand, the second stopper 4 is variably fixed in the axial direction at the lower end of the goal post 2 facing the recess 17. The upper end surface of the first stopper 5 and the lower end surface of the second stopper 4 are formed as tapered surfaces which are inclined downward from the outside of the buried pipe 1 and the goal post 2 toward the center side at the same inclination angle. I have.

The attachment structure of the second stopper 4 will be described. A fastening portion 30 having an H-shaped cross section protrudes inside the portion of the goal post 2 facing the recess 17, and the fastening portion 30 and the goal The flat bar 18 is freely slidably fitted in the longitudinal space 40 formed between the post 2 and the cylindrical wall.

A groove 19 is formed in the cylindrical portion of the goal post 2 facing the fastening portion 30 along the axial direction.
Then, the second stopper 4 is joined to the outer peripheral surface of the cylindrical wall portion where the groove 19 of the goal post 2 is formed, and a plurality of portions (3 in FIG. The threaded portions of the bolts 12a are passed through the provided bolt through holes 50, respectively, to penetrate the grooves 19 of the goal post 2, and screwed into the screw holes 51 formed corresponding to the flat bars 18.

At this time, since the second stopper 4 and the flat bar 18 press the goal post 2 by the fastening force of the bolt 12a, the second stopper 4 is firmly fixed to the goal post 2. Also, this bolt 1
When the fastening of 2a is loosened, the second stopper 4 slides axially along the groove 19 together with the flat bar 18.

Accordingly, by adjusting the axial position of the second stopper 4 with respect to the goal post 2 and fastening the bolt 12a, the second stopper 4 can be fixed at a desired axial position. After adjusting the axial mounting positions of the second stoppers 4 for the pair of left and right goal posts 2 by the same amount in this manner, when the lower end portions of the respective goal posts 2 are inserted into the buried pipe 1, the second The lower end surface of the stopper 4 is the first stopper 5
By supporting the goal post 2 by abutting against the upper end surface of the cross bar 3 and adjusting the insertion depth of the goal post 2 into the buried pipe 1, the height of the crossbar 3 from the ground is set to a predetermined height (soccer). The goal can be adjusted to 2.44m). Here, if a scale is engraved along the second stopper 4 mounting portion of the goal post 2, the mounting positions of the left and right goal posts 2 on the second stopper 4 can be easily adjusted by the same amount.

Further, since the height adjusting mechanism is provided inside the buried pipe 1 disposed underground, the regulation can be satisfied without changing the form of the soccer goal on the ground. Also, by sliding the second stopper 4,
Since the mounting position of the goal post 2 can be continuously adjusted within the set range (within the length of the groove 19), the height of the cross bar 3 can be easily and accurately adjusted.

Further, the joining surface between the first stopper 5 and the second stopper 4 is formed as a tapered surface which is inclined downward from the outside of the buried pipe 1 and the goal post 2 toward the center at the same inclination angle. As a result, a radial component force is generated and the goal post is pressed against the inner wall of the buried pipe opposite to the stopper fixing side, so that the goal post can be supported in a stable state without play. In particular, since the pressing direction is set to the direction from the infield side to the outfield side so as to coincide with the average direction in which an impact is applied to the goal post 2, it is possible to maintain a stable support state in which the backlash is hardly generated by the impact.

A rib 15 is formed on the inner peripheral surface of the buried pipe 1 at a constant distance in the circumferential direction.
And the outer peripheral surface of the goal post 2 is in contact with the target. A gap 16 is formed between each of the ribs 15 to allow sand and water from the field surface F to escape to the gap 16 and to reduce the contact area between the goal post 2 and the buried pipe 1 so as to reduce the goal. The post 2 can be easily attached to and detached from the buried pipe 1.

FIG. 6 is a front view of the bottom lid 6 of the buried pipe 1 having the rib 15 according to the present invention. A drain hole 20 is formed at a position corresponding to the center of the goal post 2 to prevent accumulation of water and sand inside the buried pipe 1.

As another embodiment of the present invention, the inner peripheral surface is threaded by a desired length from the lower end of the goal post 2 and a threadable cylindrical member is disposed on the threaded portion to reduce the amount of threading. Adjust the lower end of the cylindrical member to the buried pipe 1
It is also possible to adopt a configuration in which it is supported by abutting against the bottom surface.
