Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a batting practice device for ball games used for batting lines such as golf, tennis, and baseball.

[Conventional technology]

Conventionally, in this type of ball game batting practice device, for example, golf batting practice device, four pillars were set up on all sides in an open area such as a garden, and a frame was constructed by passing horizontal members between the tips of these pillars. There is a structure in which a net is stretched like a mosquito net in a three-dimensional space formed by a fixed frame, except for one side that becomes the striking opening, and the net is stretched from the opening side that becomes the striking opening to the net on the back side. The structure is such that you can hit the ball at the target.

[Problem that the invention seeks to solve]

However, the above-mentioned conventional device is a fixed structure with a frame on which the net is stretched, so it cannot be moved, and even if the device is movable, it cannot be folded compactly. There is a problem in that it is not portable and requires a large space for storage even when not in use.

[Means for solving problems]

This invention was made in order to solve the above-mentioned conventional problems, and consists of a pair of rectangular frame bodies that are folded into an X-shape and connected to each other so that the legs can rotate and cross each other. A net is removably stretched like a mosquito net around the three-dimensional space formed by the open legs of the pair of frame bodies, except for one side that serves as a striking opening.

Note that it is preferable that the rod-shaped frames constituting the rectangular frame body be connectable by insertion and removal, etc., near the corners of two sides facing each other.

[For production]

That is, according to the present invention, with the above configuration, a net is stretched like a mosquito net around a three-dimensional space formed by a pair of frames with legs spread in an X shape, and the net is removed when not in use. Since it is made up of a pair of folded frames, the cage can be easily assembled and folded compactly.Furthermore, casters are attached to the lower corners of the frame, making it easy to move the cage and place it anywhere. This makes it possible to effectively utilize storage space. Furthermore, if the rod-shaped frames consisting of the upper and lower frames and both side frames that make up the rectangular frame are removed by handling them at the joints near each corner, it becomes even more compact, which makes it convenient to carry. b Storage space is also reduced.

〔Example〕

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

FIG. 1 shows the assembled and used condition of a batting practice device for ball games according to the present invention, such as a device (cage) used for batting practice for golf. Each of these frame bodies 1 includes upper and lower frames 2, 3 in the shape of a letterhead, and connecting portions 2A, 2A approximately near the corners between the ends of the upper and lower frames 2 and 3.

It is framed in a vertically elongated rectangle and can be disassembled from a pair of left and right side frames 4.4 which are connected by insertion at 3A and 3A. The pair of frames 1.1 intersect with each other in an X shape and are rotatably connected at the longitudinal center of each of the side frames 4.4, with the respective connecting portions 5 and 6 being the center. The legs can be folded and opened in an X shape, and as shown in FIG. Connecting rods 7, 7 that enable the legs to be kept open are installed respectively, one end 7a of each of these connecting rods 7.7 is supported by one side frame 4, and the other end 7b is connected to the other side frame 4. By releasing the locking state of these connecting rods 7, each of the frames 1.1 can be made compact as shown by the two-dot broken line in FIG. It can be folded. Further, both the upper and lower frames 2.1 constituting each of the above-mentioned frame bodies 1.1.
Hooks 8 and 9 are attached to the inner corners of the frames 1 and 3, and these hooks 8 and 9 have a hole that serves as a striking opening around the three-dimensional space A formed by the open legs of the frames 1 and 1. The net 10 is removably stretched in the form of a mosquito net except for the side surface 1a. Furthermore, 11.11 in the figure indicates the frame bodies 1, 1.
The caster 11.11 is attached to the outer corner of one of the lower frames 3, and when the frame is assembled, the casters 11.11
The frame can be moved by lifting the other side of the frame to which it is not attached. Furthermore, 12 in the figure is the net 1 stretched like a mosquito net.
This is an inner fabric provided on the inner back surface facing one side that becomes the impact opening of the 0.

That is, in order to assemble the batting practice device described above, first, the pair of mutually connected frames 1, 1 are opened in an X shape in a predetermined space such as an open space, and the legs are locked with the connecting rod 7, so that the grounding is performed. do. Next, the net 10 is hooked into the three-dimensional space A formed by the open legs of the frame body 1.1 and suspended like a mosquito net, thereby completing the assembly. On the other hand, when storing the device, remove the net 10 from the frame 1.1,
The frame body 1.1 is folded up by removing the connecting rod 7, so that the space required for storage is small and compact storage is possible.

By the way, as the rod-shaped frame used in the above-mentioned frame 1, an aluminum alloy vibrator with a diameter of 32 mm is used, and its length is 4 to 5 meters in length on its long side.

It consists of a rectangle with a short side length of 2.5 to 3.5 m.

In the embodiment of this invention, the net is hung on both upper and lower sides by hooks provided on both the upper and lower frames of the frame, but it may also be suspended only on the upper side, and the casters can also be hung on both sides of the frame. Of course, it is possible to attach it not only to one side but also to both lower frames of both frames.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, a frame body consisting of a pair of rod-shaped frames is folded into an X shape and intersected with each other so that the legs can be rotated, and the three-dimensional space is formed by these frames. Since the net is suspended like a mosquito net, it is very easy to assemble, and since it can be folded flat, it does not require a large space for storage, and the bottom part of the frame can be easily assembled. It has the excellent effect of being able to be easily transported by installing casters on it.
