Detailed Description of the Invention

[0001]

TECHNICAL FIELD OF THE INVENTION

The present invention relates generally to a ball returning device, and more particularly to a ball returning device used for practicing ball games.

[0002]

[Prior art]

A circular frame, which is supported by elastically holding and holding a repulsion mat in the frame periphery, has not been widely known, but has already been disclosed in a patent document. This is a device for repelling a ball applied to the mat, and such a device is relatively skilled, so that the ball is first applied to the mat with a force and a direction that repels the required direction. It is effective for users who can be surely hit.

[0003]   Such a device is difficult to use for less skilled persons.

Further, there is a similar device in which the mat as described above is held without being tensioned, and the collision force of the golf ball is absorbed so that the mat is rolled to the bottom of the mat and can be recovered later.

In the prior art, it is difficult to perform a ball game using the ball, or to return the ball so that a user who is practicing can properly receive the ball. The present invention is directed to solving this problem.

[0006]

[Means for Solving the Problems]

The present invention forms a ball-receiving shape that includes a frame and a net or a component of the net that is located at the lowest position where the lower end portion is at the lowest position and is inclined and supported so as to be closest to the destination position of the ball. The present invention provides a ball returning device including one or a plurality of nets which are formed and positioned so as to be supported by the frame.

In the ball returning device, the ball-receiving shape of the net is formed by a net or a net-constituting portion forming side surfaces of the ball-receiving shape.

In the ball returning device, the ball receiving shape of the net is formed by a net or a component portion of the net forming an upper end surface of the ball receiving shape.

The ball returning device is also continuous with each side panel either integrally or by joining,
An upper end surface whose back end is continuous with the back ball receiving portion integrally or by joining is provided.

The ball returning device is also one in which the net or a constituent part of the net is held by a support frame by elastic means.

The return ball device is also one in which the elastic means comprises a spring releasably attached to the frame member of the frame.

Further, in the return ball device, the support frame has at least a main part made of a tubular member.

Accordingly, the present invention also comprises a bottom net or net component that is formed and retained and positioned to tilt the ball in a return ball position so that the ball can be returned to form a tensioned floor. This is a substantially rectangular ball receiving shape that is the catching and returning ball area of (1) or is formed by a plurality of nets.

Further, in this structure, the lower portion or another constituent portion of the net is arranged at a position lower than the ball receiving area of the net or the constituent portion of the net, and the lower portion or the constituent portion of the net falls to this portion. There is provided a frame for supporting the net having a lower portion or a component that is inclined so as to guide the ball toward the return ball position direction.

The advantage of the above-described configuration is that various receiving and returning conditions can be set for one or more balls by setting different tensions and inclination angles for each net or the components of the net. It will be possible.

As still another feature of the present invention, a return ball net or net whose rear end edge is continuous or continuous with a component of the net or net whose ball receiving position or rear end surface position is integrally or joined and whose lower end edge is inclined. The parts that are continuous with the constituent part of the net or are joined to the net are provided on both sides of the ball receiving shape of the net.

As still another feature of the present invention, there is provided an upper surface constituent portion in which both sides are respectively joined to the side surface constituent portions and a rear end portion is joined to an upper end of the rear side ball receiving portion.

As a further feature of the present invention, each of the nets or the components of the nets is held by the elastic means with respect to the support frame.

As a further feature of the present invention, the elastic means comprises a spring detachably attached to the frame member of the frame.

As still another feature of the present invention, the support frame is composed of linear members connected at respective corners by connecting means such as brackets or welding, and at least the main parts of these linear members are formed. For example, one or a plurality of openings are provided on the peripheral surface to constitute a net which can engage the hooks of the elastic means for elastically supporting the net or the constituent parts of the net. In another configuration, a hook to which a hook of a spring tool can be connected is fixed to the linear member.

As still another feature of the present invention, by supporting the nets or the constituent parts of the nets by the elastic means and the support frame, the respective nets or the constituent parts of the nets are provided on the respective side surfaces or the ball receiving end surfaces. Is formed into a substantially flat shape with a flexible tension.

As a further feature of the present invention, the net is foldable formed by knotting a string-like material such as a polyester net material having a mesh size of 2.54 square centimeters (1 square inch). Along with this, it is made of a net material with a low repulsive force.

As a further feature of the present invention, the mesh size of the net material is selected to be suitable for the size of the ball used so that the ball does not easily pass through the mesh. There is.

As a further feature of the present invention, the mesh of the net material is, for example, a golf ball,
A variety of ball sizes are selected such as tennis balls, Australian football balls, soccer balls, cricket balls, hockey balls, baseball balls, softball balls, netball balls and basketball balls. ing.

It has been found that it is desirable to form each net constituent member on each of the side surface, the rear end surface, the upper surface and the peripheral portion into a substantially flat shape under a desired tension.

Therefore, a rod or a rod-shaped cable whose longitudinal direction is provided along the edge and fixedly connected with a plurality of elastic members spaced from each other, such as a coil spring or a strap, is attached to the edge of the net. It has also been found that the structure in which the other end side of these elastic members is fixed to the frame member while being connected is advantageous.

By providing elastic members that can be engaged and disengaged, these elastic members can be first changed to increase or decrease the spring tension. In another configuration, the spring tension can be released, for example, the rear surface of the device. It is also possible to release the spring tension of (1) to slacken the net material in this portion, while keeping the spring tension on the side surface, the upper surface and the opening peripheral edge.

[0028]   The above configuration is effective when applied to a golf practice device.

In this case, even if the golf ball is driven into the rear end surface at high speed, this end surface absorbs a large amount of inertial force of the ball, but the position of the rear end surface is set so that the ball itself rolls in the entrance direction where the player is located. Has been done.

According to still another aspect of the present invention, at least an elastically retained upper portion, an elastically retained rear end portion and an inclined elastically retained opening portion are provided.

According to such a configuration, an oval-shaped ball, such as that used in Australian football, first hits the uppermost portion, then bounces off the end face on the back side, then bounces off the inclined portion, and then continues practicing. It turns out that you can kick to come back to the position.

The advantage of the above configuration is that, in the process of hitting or bouncing an elliptical ball against the net as described above, the upper surface of the ball is returned to a relatively easy return ball position for a player practicing with the ball, It is believed that the ball receiving surface, and the inclined net lower part or bottom net constituent part have the effect of correcting the posture of the ball.

That is, even if the player kicks the ball with different strengths and directions during practice, the trajectory of the ball is corrected to a straight line each time and bounces back toward the net inclined forward, so that the player can easily collect the ball. Return to where you can. It is considered that this is because the net or the components of the net bend in each case due to the pressure from the ball, and the angle of deflection is steeper on the side closer to the edge than on the other side. Due to this steep inclination effect, a stronger rebound effect than that of the more gently inclined surface on the opposite side acts in the direction of moving the ball to the center, and as a result, the above-described correction effect in the linear direction occurs. By repeating this several times, the effect is further enhanced, which is extremely useful.

This effect can be enhanced by changing the relative orientations of the nets on the top, back and front tilted bottoms. Specific measurement results and the relationship of angles found to be effective will be described later, but it goes without saying that positional relationships other than those described here also have advantages.

[0035]

DETAILED DESCRIPTION OF THE INVENTION

In order to better understand the present invention, preferred embodiments of the present invention will be described with reference to the drawings.

1 to 5, the ball returning device 1 is composed of a net structure 2 which is supported by a frame 4 by a plurality of elastic members 3 and forms a ball-shaped ball receiving shape.

The net structure is composed of a net material in which a net-like material is formed by connecting string-like materials using a conventional net material such as a conventional plastic material. The size of each mesh is set to a size that is inexpensive and at the same time can maintain the tensile strength such that the net material itself can be easily folded and a sufficient resilience effect can be exhibited even if the net material is not so elastic. In the present embodiment, it is set to 3 cm ² so that the golf ball does not fall out even if each mesh is deformed into a circle. The net in this embodiment is Quins
It is a polyester net with a standard number of SNSHNO148-30 and a total area of 210 × 48 × 2.54 square centimeters (1 square inch).

The net used on the back side is a Quins standard number 42960 knotless polyester net.

An end panel 5, two side panels 6 and 7, a top panel 8 and a bottom panel 9 which is inclined forward are provided, and the bottom panel 9 extends in the direction of a user from the curved shape of the dens. The ball is supported so as to incline toward the user with a sufficient inclination angle for rolling.

First, the respective surface portions 5 to 9 are stretched and held with relatively uniform tension by the reinforcing rod members shown by reference numeral 10 and the like which face each other. These rods 10 are inserted into and engaged with the nets provided on the respective surface portions, and a plurality of elastic coil springs 3 are fixed to each of the rods 10 so as to be separated from each other and detachable.

The outer end of each coil spring 3 is formed in a suitable manner (in the present embodiment, the hook 1
(By 1) is fixed in place on the corresponding frame member.

The frame 4 is composed of a plurality of members including the four columns 12, 13, 14, 15 and provided as separate members. Of these four columns, 12 is arranged at one end in the left-right direction on the front surface of the device 1, 13 is arranged at the other end, and two columns are provided at the rear end, that is, one end in the left-right direction at the end farthest from the user who is practicing. 14 and 15 at the other end.

In this embodiment, each of the columns 12, 13, 14, and 15 is firmly provided with an insertion port, and the side frame members 16 provided on both sides of the upper surface are provided on the end peripheral surfaces of the insertion ports. , 17 and end portions of side frame members 18, 19 provided on both sides of the bottom surface are mounted.

[0044]   Each of the frame members has a tubular shape.

Further, the horizontal frame members 20 and 21 are provided on the front surface and combined with the support columns 12 and 13, and the horizontal frame members 22 and 23 are provided on the opposite end portions to support the support columns 14 and 15.
Is combined with.

The rear ends of the members 18 and 19 provided in the longitudinal direction on the bottom side are tilted to the bottom panel 7 by being joined to the columns 14 and 15 on the rear end side while being lifted upward.

In the drawings, the schematic inclination angle of the bottom panel 7 and the two side panels 6 and 7 that are respectively inclined inward are shown, but in the present embodiment, the back side panel 5 is The device is supported in a substantially vertical position with it placed on a horizontal ground surface.

Each surface is relatively strong in tension so that, for example, when an Australian football ball is dropped from a height of 1 meter to the center of the bottom panel 7, it repels a distance of 20% or more of the fall distance. Stretched in.

In this example, the repulsion distance when a standard football ball was dropped to the center of the bottom net at a drop distance of 1 meter was 60 cm.

The other surface portions, that is, the rear surface, the side surface, and the upper surface are also stretched with the same tension as the above.

The device 1 is convenient because it can be disassembled and packed and transported, and can be manufactured at low cost, and it is extremely useful for practicing ball games and practical skills.

The second embodiment shown in FIG. 6 comprises a frame structure 20, which is supported by a net 21 which itself can impart some elasticity to the device. That is, a tubular shape that extends from the first lower front corner 22a to the rear upper corner 22 on the opposite side and further diagonally descends forward at 24 at an inclination angle of 20 ° to the lowermost end portion 25 extending forward. Frame is provided.

Further, the tubular frame passes through the transverse portions 26 to 27 and reaches from the diagonal portion 28 to the front corner 29 and the front lower corner 30.

A spacer 31 is provided between the front cross section 32 and the rear lower cross section 26.

Fixing portions 33, 34, 35, 36 for fixing the net are provided at positions where the tubular member is bent by the tension of the net, whereby the net flexibly receives a load. ing.

Further, the reason why the extending direction of the tubular member is slightly complicated is that the tubular member can be constructed with few welding points.

Further, a ball 37 is provided, and the ball 37 has a needle thread 38 and an elastic member 39.
, 40.

With this configuration, even if the ball 37 is hit with a strong force and hits any part of the net, the ball 37 can be returned to the hit position shown by a dynamic action.

A third embodiment is shown in FIGS. 7 and 8. In this third embodiment, the bottom frame is formed with a diagonal structure similar to that of the top frame.
For example, a rear corner 44 provided opposite to both sides of the rear surface from both corners 42 and 43 of the front bottom portion.
, 45, two diagonal line portions 40, 41 are linearly extended.

[0060]   This increases the elastic support effect.

The net 48 is loosely stretched and supported in a posture in which inertial impact from the golf balls in the net structures 46 and 47 is absorbed and the balls are returned to the front lower edge portion 51 via the inclined floor 49. There is. The inclination angle is not particularly defined, but it is particularly convenient when it is about 10 to 30 °.

The back net is particularly inclined at 20 ° with respect to the vertical direction in that it can further apply downward force to the ball hitting it, and that rebound practice can be performed from the back side of the entire device. Be beneficial.

FIG. 9 shows a state in which the net 58 is connected to the frame using the surface fastener (Velcro (trade name)) type locking bands 56 and 57. In this configuration, the frame provides additional elasticity. Further, the reinforcing material 59 is provided by inserting it through the central portion of the joint material 60.

In order to play Australian football using this device, first, when the player kicks the ball toward the front of the device, the ball hits the upper surface of the device and continues to move forward while descending, and abuts on the rear surface portion 5. . With this series of operations, the ball continues to rotate and each net surface portion bends to generate a repulsive effect, so that a force is applied to the ball in a posture-correcting direction.
The direction of travel changes and contacts the bottom panel. At this time, the ball comes into contact with a force having a size and directionality that repels the ball in the direction of the player, so that the player can collect the ball in the middle of this return path.

With the above configuration, when practicing continuous kicks, the player can not only take a good kick to some extent but also take a ball at a position within a range that can be easily collected with a reasonable probability. Can be collected.

[0066]   The advantage of this effect is clear.

When the player practices alone, the kick can be repeatedly repeated while correcting the kick for the best effect, and the ball returns at a relatively quick and corrected position during each kick. , Very convenient.

[0068]   Suitable uses for the device 1 are not limited to Australian football practice.

It has been confirmed that the device can be used for other ball games, and is particularly useful for golf.

In this case, the rear surface portion 5 is loosened so as not to repel, while the side surface, the top surface and the bottom surface panel are kept under tension.

As a result, when the player practices golf, a soft net is arranged at the end of the net device where the ball is to be hit, so that the ball is driven into the opening of the device 1 with extremely strong force. However, this ball is definitely a soft net panel 5
The speed is absorbed by being guided to and rolls on the bottom panel 7 and returns to the player.

The second embodiment shown in FIG. 6 is the same as the first embodiment except that a cable 24 is provided instead of the rod 10.

As a further alternative, part of the device 1 can be used for other practice applications.

For example, one of the side panels can be used as a rebound net for practicing tennis.

With such a configuration, it is also possible for two, three or more people to share the same device without hindering each other and to practice separately around this device. is there.

For example, if one player is practicing Australian football, another player may also use the side panels of the device to practice tennis without fear of interfering with each other. In this case, both shall be outside the device.

The above-described effect of correcting the trajectory of the ball from the center is usually in a tense state, and when the pressure due to the collision of the ball is applied, the surface portion, that is, the net, is deformed into a substantially V shape and is inclined. It is thought that this is due to the shape of the net that both sides have the effect of moving toward the center.

When the above moving operation is repeated on each of the three surface portions arranged in a straight line, the advantage of the effect of the above-described dynamic action becomes extremely large.

The effect of correcting the trajectory toward the center, which is considered to be associated with the present device, is that when the ball hits one side of a tensioned net, the shorter side of the net makes a larger angle. Therefore, the characteristic of the net that the repulsive force toward the central part becomes large seems to be a factor.

If this visible effect is repeated over several rebounds, it is also possible to adjust to further increase the advantage of this central trajectory correction effect.

[0081]   This is especially true for return ball panels, and especially top panels.

The device and method are as effective in handball practice as in Australian football. In this case, the ball can be efficiently returned by throwing it to the back side of the net and bouncing it at the lower end side of the net, for example.

It has also been found that both side panels can be used to practice handball in a variety of ways.

[0084]   In addition, the device can be applied to baseball and used to return thrown balls.

Furthermore, the present device can be applied to cricket and used for collecting balls after practice of hitting the model stamp.

A further aspect of the present invention is a foldable panel configured to bounce the ball for performing or practicing a ball game, each of which is formed of a net formation or the like and held under elastic pressure. Is provided with at least two flat surfaces, and each panel is generated by a structure in which a ball hitting the panel is repulsed by exerting a trajectory correction effect in the central direction.
