Acceptable. As a result, the falling ball, whose momentum has been reduced, rolls on the slope of the lower end of the bent portion 34a, is guided by the guides 22 (horizontal guide 22a, vertical guide 22b), and is thrown into the opening 21. A thrown ball is supported by an arm 22 as a shooting mechanism provided inside the opening 21, and the arm 22 shoots the ball forward from the opening 21 by means of a spring mechanism (not shown).

The ball ejection unit 2 may be mechanically driven or electrically driven. Also, the direction of ejection of the ball, the ejection speed, the ejection interval, etc. may be controlled to arbitrary settings. With respect to the shooting direction, for example, in the case of basketball, the ball ejection unit 3 may be rotated within a range of 180 degrees in front of the goal 4. In the case of beach basketball, etc. 1 may be expanded so that the ball launcher 3 rotates in a range of 360 degrees around the goal 4. FIG.

The net supporting portion 3 supports four net supports 31. In this case, the expandable portions 38 (see FIG. 1) of the net supports 31 are relaxed to shorten the upper/middle/lower portions. Shown in the closed state. The net supports 31a and 31b of the net supports 31 are stored in a state in which the lower part containing the upper/middle part is dropped into the lower part of the net support 3, while the net supports 31c and 31d are stored. , in a state in which the lower part accommodating the upper/middle part is supported by a pedestal 39 (described later with reference to FIGS. 5 to 7) provided at a predetermined position inside the net support part 3, each shown. The net struts 31 take the positions of the

net struts

31a and 31b when stored in the net supporting portion 3, and the positions of the

net struts

31c and 31d when the net 32 is stretched.

Next, how the goal 4 is attached to the net support portion 3 will be described with reference to FIGS. 5 to 7. FIG. 5 and 6 show FIG. 4 viewed from the rear, and FIG. 7 shows a case where FIG. 4 is partially enlarged and viewed from the side.

As shown in FIG. 5, both the left goal post 41a and the right goal post 41b of the goal 4 have upper and lower connecting portions 35 (lower connecting portions 35a , and the upper connection portion 35b). Specifically, the net supporting portion 3 has a lower connection portion 35a and an upper connection portion 35b for attaching the goal post 41 to the back surface 351 thereof, and the lower portion of the goal post 41 is pivotally attached to the lower connection portion 35a. A corresponding portion of the goal post 41 is attached to the upper connecting portion 35b. A fixing means such as a wing bolt is used for axial attachment or fastening of the goal post 41 .

As for the mounting procedure of the goal post 41, as shown in FIG. 6, first, with the goal 4 laid down, the lower part of the goal post 41 is rotatably pivoted to the lower connecting portion 35a. Then, after the goal 4 is raised, the corresponding portion of the goal post 41 is fixed to the upper connecting portion 35b. FIG. 7 shows a state in which the goal post 41 is erected on the back surface 351 of the net support portion 3. As shown in FIG. When removing the goal 4, conversely, after removing the goal post 41 from the upper connection portion 35b, the lower part of the goal post 41 is removed from the lower connection portion 35a with the goal 4 laid down.

In this way, by rotatably attaching the lower part of the goal post 41, the goal 4 can be attached to or removed from the net support part 3 in a state of being laid down, so that the attachment work can be performed easily. Even if there is only one person, the goal 4 can be erected or dismantled on the back surface 351 of the net support part 3 safely and without difficulty.

In this embodiment, the goal post 41 is detachably erected on the outside of the back surface 351 of the net support portion 3. Alternatively, the goal post 41 may be placed on the back surface 351 of the net support portion 3. It may be erected inside, on the upper surface (top plate 37) or side surface of the net support portion 3, or on the base 1 in a detachable manner. Among these, when standing on the upper surface of the net support portion 3, for example, the upper connecting portion 35b that can be rotated is provided on the upper surface, and the goal post 41 is axially attached. may be applied. Moreover, when standingly installed on the base 1 , the lower connection portion 35 a may be provided on the base 1 and the upper connection portion 35 b may be provided on the net support portion 3 . In this manner, the lower connection portion 35a and/or the upper connection portion 35b can be appropriately set according to the placement location of the goal post 41. FIG.

Here, in FIGS. 5 to 7, unlike FIG. 3, casters 45 (casters 45a on the left goal post 41a and casters 45b on the right goal post 41b) are provided at the lower end of the goal post 41 or the lower connection portion 35a. It shows how it is provided. When the weight of the goal 4 increases due to the material of the goal 4, the weight of the goal 4 is transmitted to the floor surface by providing the casters 45, thereby lightening the load on the net support portion 3. Also, the effect of increasing the stability when moving the shooting practice device 100 can be expected. In addition, it is also possible to previously attach the casters 45 to the goal post 41 so as to be rotatable. It can be easily transported by a person.

A supplementary note about the pedestal 39 mentioned above. As shown in FIGS. 5 and 6, inside the net supporting portion 3, a pedestal 39 is provided for supporting the net support 41 at a position where a desired height of the net support 41 can be obtained. When viewed from the side of the net support portion 3, it is as shown in FIG. support the bottom edge of the In FIG. 7 , as in FIGS. 5 and 6 , the net supports 31 a and 31 b are stored in a state in which the lower part accommodating the upper/middle part is dropped into the lower part of the net supporting part 3 . , the net struts 31c and 31d are shown in a state in which the lower part containing the upper/middle part is supported by the pedestal 39. As shown in FIG.

Next, the folding structure of the net struts 41 will be described with reference to FIG. FIG. 8 shows a case where the net struts 41 are folded backward in the mode of FIG.

The folding part 44 has a hinge structure and is provided with a stopper to prevent unintended folding. When necessary, the stopper can be released to fold the goal post 41 backward. Maintenance management such as storage and transportation of a certain place can be easily performed.

Furthermore, although FIG. 8 shows a mode in which the goal strut 41 is folded once backward, another folding portion is provided between the folding portion 44 and the backboard 42 to further fold the backboard 4 forward. You may do so. By folding the goal post 41 in a Z shape in this manner, the storage and transportation of the shooting practice device 100 can be facilitated even with the goal 4 attached.

(Other aspects of the shooting practice device)
As described above, the shooting practice device 100 can also be applied to similar ball games other than basketball, such as beach basketball, netball, korfball, sesteball, etc., in which a goal 4 without a backboard 42 is set. can be done. In these ball games, it is possible to shoot from anywhere within 360 degrees around the goal 4. Therefore, in the above explanation, the base 1 of the shooting practice device 100 is expanded to cover the net behind the goal 4 as well. It has been described that the goal 4 may be sandwiched between the two net support portions 3 by providing the support portion 3 so that the net 32 covers 360 degrees around the goal 4. The goal 4 may be surrounded by a relatively large net support portion 3 . In this alternative embodiment, for example, the goal post 41 of the goal 4 is similarly erected on the base 1 or the net support portion 3, and the goal post 41 is arranged so as to pass through the net mounting rim 33. , the net 32 on the four sides surrounds the entire periphery of the goal 4 to recover the ball.

In addition, the shooting practice device 100 may be configured so that the height of the goal 4 (goal ring 43) can be adjusted so that not only advanced players but also beginners and children can practice shooting. . For example, all or part of the upper portion of the goal post 41 may be telescopic like the net post 31 . In this case, the length and angle of the net support 31 are adjusted so that the height of the upper side of the stretched net 32 is harmonized with the height of the goal 4 (goal ring 43). If the goal post 41 is telescopic, it can be easily stored and transported in places with height restrictions even when not in use.
