Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sports goal constructed by stretching a net member behind a goal frame member.

[0002]

2. Description of the Related Art A prefabricated sports goal usable for mini soccer is shown in U.S. Pat. No. 5,421,586. Here, a L-shaped connector and an I-shaped connector are used to form a goal frame member by connecting a plurality of metal pipes in an annular shape. The goal frame member has an appearance that it is bent into an L shape at the center when viewed from the side, and the U-shaped foundation part installed on the ground surface (including the floor surface) on the back side and the foundation part. It has a U-shaped opening frame that is erected from both ends. The net member whose edges are constrained along the entire circumference of the goal frame member forms a bag-like space that hangs behind the goal frame member.

[0003]

Problems to be Solved by the Invention US Pat. No. 542158
The sports goal shown in No. 6 has a structure in which the net member hangs from the U-shaped opening frame, so that the assembled goal net has a flat appearance and lacks depth, so that a so-called side net is not formed. Therefore, if the angle of the shot is shallow or weak during mini soccer, the ball may not be properly captured by the goal net due to contact with the hanging net member. Further, the goal net is likely to come into contact with the hands and feet of the player who plays in front of the goal net, which may hinder normal play. Further, when used as a ball-picking net for a volleyball, the ball easily gets under the net member, and it is difficult to take out the captured ball because the hand or head interferes with the net member. In addition, since the dripping part of the net member comes into contact with dirt or mud and becomes dirty, the life of the net member is short, and once it is used outdoors, it cannot be brought into a flooring-finished gymnasium.

Therefore, a net member is strongly stretched between the upper side (horizontal part) of the opening frame part and the ground side (part parallel to the goal line) of the foundation part, and the L-shaped goal frame member seen from the side. A structure has been proposed in which both ends of each of the two are connected to each other by a net member in a slanting linear shape. However, when a strong tension is applied to the net member, the ball that has jumped in is repelled by the net member and easily jumps out of the goal. In addition, when a strong ball is kicked in, a large impact force is applied to the net member and the goal frame member, so the net is broken, the metal pipe and the connector are deformed, and the entire goal frame is distorted, and disassembling and assembling. Also results in problems. In particular, a large force acting to bend both sides inward acts on the L-shaped bent portion of the goal frame member when viewed from the side.

If the net member and the goal frame member are reinforced in order to secure the strength capable of withstanding a large impact force, the weight of the entire sports goal increases and the structure becomes complicated, which is convenient for assembly and transportation. Is damaged.

An object of the present invention is to provide a sports goal in which a net member can be formed behind a goal frame member by lifting the net member without giving tension to the net member.

[0007]

According to a first aspect of the present invention, a U-shaped opening frame is formed from both ends of a U-shaped foundation portion which is assembled by connecting a plurality of pipe members and is installed on the ground surface. In a sports goal having a goal frame member in which a portion is erected, and a net member whose edges are constrained along the goal frame member to form a bag-shaped space behind the opening frame portion,
A flexible cord-shaped member extending obliquely downward from the end of the horizontal portion of the opening frame portion to the rear side and reaching the base portion is provided.

According to a second aspect of the present invention, the cord-shaped member in the first aspect has a mounting structure capable of forming a ring by closing the end portion around which the pipe material is circulated with one touch.

According to a third aspect of the present invention, in the mounting structure according to the second aspect, the hook side and the ring side of the surface fastener are arranged on the opposite sides.

According to a fourth aspect of the present invention, the cord-shaped member in the structure of the first aspect has a ring through which the pipe material penetrates, and the goal frame member is mounted with the cord-shaped member. The pipe member is detachable in the vicinity of the portion.

According to a fifth aspect of the present invention, the cord-shaped member in the first, second, third, or fourth structure is constituted by a rubber cord which is stretched and stretched.

According to a sixth aspect of the present invention, the first portion is held substantially horizontally from the ground surface at a predetermined height to form the upper limit of the opening frame, and the first portion is installed on the ground surface behind the first portion. A second portion for supporting the standing posture of the opening frame from the rear side;
In a sports goal having a part and a second part which are connected in a plane and form a dead end behind the opening frame, the ends of the first part and the second part on the same side are connected. And a flexible cord-shaped member that supports the net member and lifts the net member backward.

[0013]

In the sports goal according to the first aspect, the circumference of the net member is constrained along the goal frame member assembled by connecting a plurality of pipe members. Since the net member is gently attached to the goal frame member, the ball that has jumped in is decelerated without repulsion. The goal frame member is
It has an L-shaped appearance when viewed from the side, and both ends of the L-shape are obliquely connected to each other, and a string-shaped member is stretched. The net member has no tension, but is diagonally supported by the string-like member and lifted up to the rear side.

In the sports goal according to a second aspect of the invention, the closed end is formed by orbiting the end of the string-shaped member around the pipe material (including the L-shaped or I-shaped connector).
The string member is attached to the goal frame member.

In the sports goal according to the third aspect, one-touch mounting is realized by winding the mounting structure around the cross section of the goal frame member and overlapping the claw side of the surface fastener with the ring side and lightly pushing. Also, by peeling off the claw side of the surface fastener from the ring side, one-touch removal is realized.

In the sports goal according to the fourth aspect, the string-shaped member is attached to the goal frame member by penetrating the pipe material with a closed ring formed in advance at the end of the string-shaped member. The string-like member is attached by partially disassembling the goal frame member at the connecting portion of the adjacent pipe members.

In the sports goal according to the fifth aspect, since the string-shaped member is expandable and contractible, the tension increases when the string-shaped member is displaced in the direction perpendicular to the tension direction as compared with the case where a string without expansion and contraction is used. Is small. That is, when a ball or a person comes into contact with the string-like member, the force of bending both sides of the L-shape of the goal frame member viewed from the side inward is small.

In the sports goal according to the sixth aspect, the net member is supported by stretching the string member between the first portion and the second portion at both left and right ends of the goal frame member. This allows
Avoid the sagging of the net members to ensure sufficient depth in the appearance of the goal net, and form so-called side nets on both sides of the goal net.

[0019]

BEST MODE FOR CARRYING OUT THE INVENTION A mini soccer goal of an embodiment will be described with reference to FIGS. As shown in FIG. 1, the mini soccer goal of the embodiment has a net member 12 on the rear side of a goal frame member 11 assembled in an L shape when viewed from the side.
Is installed. The goal frame members 11 are bent portions 1 at both ends of a U-shaped base portion 13 which is installed on the ground surface and serves as a base.
5, the U-shaped opening frame portion 14 forming the goal frame is erected. The net member 12 is the goal frame member 11
It is formed to be larger than, and is attached to the goal frame member 11 in a slack state in which tension is not applied. The edges of the net member 12 are constrained along the base portion 13 and the opening frame portion 14 at predetermined intervals. This restraint is performed using a surface fastener (so-called magic tape), and the goal frame member 11
The outer periphery of the cross section is wound with the surface fastener integrally with the edge of the net member 12, and the claw side and the ring side of the surface fastener are overlapped and engaged with each other in a tightened state.

The upper side of the opening frame portion 14 (corresponding to the first part of the invention) is horizontally supported at a predetermined height from the ground surface and constitutes the upper limit of the opening frame of the goal. The ground side of the foundation 13 parallel to the goal line (corresponding to the second part of the invention) is installed on the ground surface on the back side of the upper side and supports the standing posture of the opening frame of the goal from the back side, Its weight places the center of gravity behind it to prevent the mini soccer goal from tipping forward. The net member 12 connects the upper side and the ground side in a plane shape to form a dead end surface on the back side of the opening frame portion 14. Two string-like members 20 are diagonally arranged, connecting the ends on the same side of the upper side and the ground side. The string-like member 20 supports the net member 12 from below and lifts it to the back side, and along the triangle formed by the pipes 13A and 14A and the string-like member 20 without generating tension in the net member 12 itself. Form clear side nets to the left and right of the goal net.

The string-shaped member 20 is made of an elastic rubber string 21.
A mounting structure 22 capable of one-touch mounting on the goal frame member 11 is sewn to both ends of the. Mounting structure 22
2 is made of a flexible canvas cloth, and as shown in FIG. 2, the hook side 22B of the surface fastener is sewn on the front side and the ring side 22A of the surface fastener is sewn on the back side. The mounting structure 22 is wound around the cross section of the goal frame member 11 and the front and back surface fasteners are overlapped with each other to be mounted with one touch. Further, by lightly peeling off the engaged surface fastener, the goal frame member 11 can be separated with one touch. The rubber cord 21 is set shorter than the distance between the upper side of the opening frame portion 14 and the ground side of the foundation portion 13,
In the state where the string member 20 is attached to the goal frame member 11, the rubber cord 21 is stretched and has a tension, and the upper side of the opening frame portion 14 and the ground side of the foundation portion 13 are linearly connected to each other to connect the net member 12 with each other. Support weight.

The goal frame member 11 includes eight aluminum pipes having a diameter of 40 mm and a wall thickness of 2 mm, which are L-shaped and I-shaped.
By connecting with a vinyl chloride connector formed in a V shape, the whole assembly is assembled into an annular appearance bent at a right angle at the central bending portion 15. At the upper side of the opening frame portion 14 and the ground side of the foundation portion 13, two pipes are linearly connected by an I-shaped connector. The pipes on the other sides are connected to each other by an L-shaped connector bent at 90 degrees.

L-shaped connectors are fixed to both ends of the left and right pipes 13A of the base portion 13 in advance with a connection angle at which they intersect each other at a right angle. As a result, the intersection angle between the ground side of the base portion 13 and the pipe 14A is fixed, and the rigidity of the entire goal frame member 11 is increased. An L-shaped connector is previously fixed to the upper ends of the left and right pipes 14A of the opening frame portion 14. The ends of the other pipes are detachable from the connector, and the pipe is inserted into the connector and fixed with a pin (not shown) to prevent it from coming off. With this structure, the mini soccer goal can be disassembled and assembled in a short time as needed.

According to the mini soccer goal of the embodiment, since it can be disassembled and stored in a narrow place when it is not used, it is possible to efficiently use a limited area of a ground, a gymnasium or a storage cabinet for multiple purposes. In addition, the minimum number of lightweight parts is used, and the structure that allows the goal frame member 11 to be assembled and the string member 20 and the net member 12 to be mounted by one-touch operation is adopted. It can be assembled and disassembled in a short time, and most of the limited exercise time can be spent playing mini soccer.
Replacing the string-like member 20 with an oblique pipe, the pipe 1
It is not necessary to use a three-branch connector as in the case where the angle between 3A and the pipe 14A is supported in a slidable manner.

Further, since the net member 12 is mounted on the goal frame member 11 without applying tension, it is supported from below by the string member 21 stretched and applied with tension. The appearance becomes three-dimensional with depth, and clear triangular side nets are formed on the left and right sides of the goal net. Therefore, it is possible to enjoy the real pleasure of mini soccer in which the side net is swayed by the ball kicked into the opening frame portion 14 at a shallow angle. Then, a ball that jumps in at a shallow angle is hindered by the vertically hanging net member 12 and jumps out, or a player's limbs near the goal line contact the vertically hanging net member 12 to hinder the play. There is no possibility that the ball will sneak under the net member 12 that hangs down on the (floor surface) and cannot be taken out. Further, since the net member 12 is supported by the string-like member 21 and does not come into contact with the ground surface, the net member 12 is not trampled by being trampled or soiled with mud, and the gymnasium with a clean floor can be used outdoors without worrying about dirt. You can move to.

Further, since the net member 12 is attached to the goal frame member 11 without giving tension, the momentum of the ball is generated without generating a large tension on the net member 12 when a strong ball is kicked in. Can be attenuated. Therefore, the balls that have jumped into the opening frame portion 14 are
When the ball collides with the net member 12, the net member 12 is broken by exceeding the tension limit when the ball collides with the net member 12, or the tension of the net member 12 causes a large moment in the bent portion 15 to cause an L-shaped portion. There is no possibility that the outer appearance of the goal frame member 11 is deformed by bending inward, or the connection portion between the connector and the pipe is damaged and the connection is not loosened.

Further, since the elastic cord 21 that can be expanded and contracted is used for the string-shaped member 20, the net member 1 is always slack.
2 can be supported, and even when the ball directly collides with the string-like member 20, the increase of the bending moment acting on the bending portion 15 connecting the opening frame portion 14 and the base portion 13 can be small.
Therefore, compared with the case where the string-shaped member 20 is made of a material having a small degree of expansion and contraction, the rigidity required for a mini soccer goal can be secured even if the goal frame member 11 has a lightweight and simple structure.

Although the goal frame member 11 which can be freely assembled and disassembled is adopted in the embodiment, the present invention can also be applied to a goal frame in which the connecting portion of the pipe is fixed by welding or the like.
With respect to the materials of the pipes and connectors and the connecting structure, selections and modifications other than those described here may be made. For example,
The angle between the pipe 13A and the pipe 14A is not limited to 90 degrees, and may be 60 degrees or 110 degrees. The word L-shaped as used in the description refers to the two sides intersecting at various angles, including right angles. Further, in the embodiment, the string-shaped member 20 in which the mounting structure 22 is wound around the outer periphery of the cross section of the goal frame member 11 and the end thereof is closed by the surface fastener is adopted, but as shown in FIG. A string-like member 30 having a flexible cloth ring 32 fixed to the end may be adopted. Here, the pipe 11A and the connector 11B adjacent to the mounting portion are temporarily disassembled, and the pipe 11A or the connector 11B is passed through the ring 32 that is closed from the beginning. As a result, the string-shaped member 30 is stretched obliquely while the rubber string 31 is being tensioned. The pipe 11C is fixed to the connector 11B in advance. In addition, although a mini soccer goal has been described in the embodiment, the present invention can be used as another ball game or competition, or as a simple ball picking or fence.

[0029]

According to the invention of claim 1, even if the net member is attached to the goal frame member in a sufficiently slack state,
Since the net member is supported on the back side by the string-like member, a three-dimensional appearance is formed on the goal net, and so-called side nets are formed on the left and right side surfaces. And, compared to the case where the net member is strongly stretched over the goal frame member to form a similar three-dimensional appearance, the impact that acts on the net member and the goal frame member when the ball or person comes into contact with the net member. Since the force is small, the required rigidity can be sufficiently secured even if a lightweight and simple structure is adopted.

According to the second aspect of the present invention, since the end portion of the string-shaped member can be attached to the pipe member with one touch by the attaching structure, the goal frame member that has already been assembled can be easily disassembled without disassembling it later. A string-like member can be attached. For example, the net member may be attached to the goal frame member and installed at a predetermined place before the goal frame member can be attached.

According to the third aspect of the invention, since the end portion of the string-like member is attached to the pipe member using the surface fastener,
Reliable attachment / detachment can be achieved with a light force, and even if the attachment / detachment is repeated many times, the engagement force is not impaired.

According to the invention of claim 4, the string-shaped member is composed of a closed ring, and the pipe material is penetrated through the ring to assemble the string-shaped member. There is no.

According to the fifth aspect of the present invention, since the cord-shaped member is made of a rubber cord, the net member can be linearly supported without sagging even if an excessive tension is set. Further, even when an impact force is applied to the string-shaped member itself, the increase in the moment acting on the L-shaped bent portion of the goal frame member is small, so even if the structure is simple and lightweight, the goal frame member is not deformed or damaged. You don't have to reach it.

According to the invention of claim 6, the first portion and the second portion
Since the string-like member is stretched between the parts to support the weight of the net member on the back side, even if the net member is attached to the goal frame member in a slack state, the goal net has a three-dimensional appearance. Thus, so-called side nets are formed on the left and right side surfaces.
