 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a foldable net according to the present invention, FIG. 2 is a perspective view of the foldable net of the present invention with some components removed, and FIG. 3 is a plan view taken along the line AA of FIG. 4 is a plan view of a frame body which is a basic element of the folding net according to the present invention, and FIG. 5 is an enlarged cross-sectional view of the frame body. In each of the above figures, 1 is a frame body, 2 is a belt-shaped body, 3 is a leaf spring, 10a and 10b are both side surface parts, 11 is a back surface part, 12 is a front surface part, 13 and 13 are both side surface nets, and 14 is A back net, 16 is a target cloth, and 17 is a connecting cord.

The foldable net of the present invention shown in FIG. 1 is configured as a quadrangular pyramid as a whole, and has a frame body 1 described below as a basic element. Therefore, the frame body 1, which is a basic element of the foldable net, will be described. In FIG. 4, the frame body 1 is formed by bending one continuous leaf spring 3 into a substantially figure-eight shape, and is elastically bendable even after the frame body is formed. The frame body 1 has a central intersection 4 fastened with a screw and is composed of two ring-shaped bodies of equal size. As shown in FIG. 5, the frame body 1 is housed inside a belt-shaped body 2 having a bag-shaped cross section and a substantially 8-shaped overall shape. The strip 2 is made of synthetic resin, synthetic leather or the like.

Next, as shown in FIG. 2, the frame body 1 is bent in two folds with the central intersection 4 as the apex, and the bottom surface is flattened so that the overall shape is a mountain shape. As a result of the mountain shape, the frame body 1 is composed of both side surface parts 10a and 10b, a back surface part 11, and a front surface part 12 which are formed in a space. Both lower end surfaces 15 of both side surface portions 10a and 10b of the frame body 1 are horizontally bent, respectively, and as a result, the respective side surface portions 10a and 10b, the back surface portion 11 and the front surface portion 12 are formed in a substantially triangular shape. The overall shape of the frame body 1 is a pyramid shape having a substantially square bottom surface.

A side net 13 serving as a cover adapted to the shape is stretched on each of the side surface portions 10a and 10b, and a back net 14 of the cover is also stretched on the back surface portion 11. It is set up. Specifically, the side net 13 and the back net 14 are sewn and fastened to the peripheral edge of the strip 2 at the edges thereof, and are made of a net or a cloth. The lower ends of the front portions of the both side surface portions 10a and 10b are connected by a connecting cord 17 so that the front surface portion 12 does not expand due to the elastic force of the frame body 1. The frame body 1 is constrained in a pyramidal shape by the both side nets 13 and 13 and the connecting cord 17 so that the entire shape is not restored to the substantially original shape of a figure 8.

As shown in FIG. 1, a cloth body 16 having a shape adapted to the shape of the back surface portion 11 is detachably attached to the front surface of the back net 14. The target cloth body 16 has stoppers 18 at its respective corners, and is attached by hanging the stoppers 18 on the frame body 1. A reinforcing cloth 19 is attached to the lower portions of the both side surface portions 10a and 10b, and a reinforcing cloth 20 is attached to the lower portion of the back surface portion 11. The mountain-shaped frame body 1 is fixed to the ground by a plurality of fixing tools 21 on the lower end surfaces 15 of the both side surface portions 10a and 10b.

Next, a method for folding the folding net according to the present invention will be described. Conceptually, the convolution method of the present net tool is that the frame body forced into the shape of a pyramid is made into a double shape with the center intersection point as a boundary to form a close double wheel shape. The frame body is twisted into a figure eight shape, and then folded into two folds to form a quadruple ring shape for convolution. Specifically, as shown in FIG. 2, the frame body 1 from which the target cloth body 16 has been removed is brought into close contact with the above-mentioned both side surface portions 10a and 10b so as to be in contact with each other. The shape. Here, the frame body 1 is released from the constraint to be shaped like a pyramid which was received by the both side nets 13 and 13 and the connecting cord 17, and is forced to have a double-ring circular shape. Then, the double ring-shaped frame body 1 is further folded into two folds to have a semicircular shape shown in FIG. 7. Then, the frame body 1 is screwed, and after the state shown in FIG. 8, the elastic force of the frame body 1 itself forms a quadruple ring shape which is in close contact with the annular shape and the flat shape shown in FIG.

As shown in FIG. 10, the quadruple ring-shaped frame body 1 is stored in the storage case 31 through the opening 32. Further, the opening 32 is closed by the fastener 33. The storage case 31 has a lowering string 34 and is easy to carry.

On the other hand, the assembling method is performed in the reverse order of the folding method. First, the twist of the quadruple frame body 1 shown in FIG. 9 is returned. As a result, the frame body 1 undergoes the shape shown in FIG. 8 due to the elastic force of the frame body 1 and becomes the semicircular shape shown in FIG. 7. Further, as shown in FIG. 6, both side surface portions 10a, 10b are formed. 2 come into close contact with each other in two pieces, and finally, as shown in FIG. 2, due to the restoring force to return to the figure 8 shape of the frame body 1 itself, the whole shape of the pyramid is formed. As shown in FIG. 1, a cloth body 16 is attached to the frame body 1 and is fixed to the ground by a plurality of fixing tools 21. And it is mainly used as a golf practice net. Needless to say, it can be used as a tent for people to enter and leave without attaching the target cloth body 16.
