Description
【０００１】[0001]
この考案は、野球やソフトボールの打撃練習やテニス、サッカー等の球技等の 練習等に使用される投球装置に関し、特にピッチャー等の投球フォームの映像に 合わせて投球する投球装置の改良に関する。 The present invention relates to a pitching apparatus used for baseball and softball hitting exercises, and practice for ball games such as tennis and soccer, and more particularly to an improvement of a pitching apparatus for pitching in accordance with a pitching form image of a pitcher or the like.
【０００２】[0002]
従来の投球装置５として、例えば図５に示すように、本出願人によって提案さ れたものがある（実用新案登録第３０３２６４５号掲載公報）。これは、ピッチ ャーの投球フォームを投球マシン５０に隣接したスクリーン５５に映写して投球 するもので、打席Ｂ側の傾斜床面４に形成された凹所４０内に設置され映写器６ ０からスクリーン５５にピッチャーの投球フォームを映写して、その映写された ピッチャーの投球の手が通過する箇所に形成された開口５６より同期してボール 発射手段５１、５２からボールを投球するようにしている。 As a conventional pitching apparatus 5, for example, as shown in FIG. 5, there is a pitching apparatus proposed by the present applicant (Japanese Utility Model Registration No. 3032645). In this method, a pitcher's pitch form is projected on a screen 55 adjacent to the pitching machine 50 to throw a pitch. The pitcher is set in a recess 40 formed on the inclined floor 4 on the side of the bat B, and is projected from the projector 60. The pitcher's pitch form is projected onto the screen 55, and the ball is thrown from the ball launching means 51, 52 in synchronization with an opening 56 formed at a location where the projected pitcher's hand passes. .
【０００３】 この場合、映写器６０は、それを収容している凹所４０を覆っている防護被い ４５によって、打席Ｂ側からの打球から保護されている。防護被い４５は、設置 されると上面がほぼ傾斜床面４の勾配αで傾斜し、スクリーン側の矩形状本体部 ４６と打席側の三角形状部４６とから構成されており、また投映部６１に対応し て若干上に突き出た低い突出部４７を有している。突出部４７も平面視で三角形 状をなしており、全体として防護被い４５は、傾斜床面４を転がって来るボール を止めないようになっている。矩形状本体部４６には、スリット状換気孔４９が 形成されている。In this case, the projector 60 is protected from a hit ball from the bat B side by a protective cover 45 covering the recess 40 accommodating the projector 60. When the protective cover 45 is installed, the upper surface thereof is substantially inclined at an inclination α of the inclined floor surface 4, and is composed of a rectangular main body portion 46 on the screen side and a triangular shape portion 46 on the bat side. A low protrusion 47 slightly protruding upward corresponding to 61 is provided. The projecting portion 47 also has a triangular shape in a plan view, and the protective cover 45 as a whole does not stop the ball rolling on the inclined floor surface 4. A slit-shaped ventilation hole 49 is formed in the rectangular main body 46.
【０００４】[0004]
上述のような従来の投球装置５では、映写器６０の大部分が凹所４０に収容さ れていて、その防護被い４５も厚みだけが床面４から出ているだけであり、打球 が当たって打席Ｂの方に跳ね返す大きな物が床面４上になくなっている点で優れ ている。然し、まだ防護被い４５の厚みと、その低い突出部４７だけが床面４か ら出ている為に、希に打球が当たって打球方向とは異なった方に跳ね返ることが ある他、まだ打者に床面４の平坦さに若干の違和感を与えることがある。 In the conventional pitching device 5 as described above, most of the projector 60 is housed in the recess 40, and the protective cover 45 has only the thickness protruding from the floor surface 4; It is excellent in that large objects that bounce toward bat B upon hit are no longer on the floor 4. However, since only the thickness of the protective cover 45 and the low protruding portion 47 protrude from the floor surface 4, the hit ball may rarely hit and rebound in a direction different from the hitting direction. The flatness of the floor surface 4 may give the batter a sense of strangeness.
【０００５】 本考案は上記従来の事情に鑑み案出されたものであって、打者が違和感を感じ ないように打席とスクリーンとの間の傾斜面の平坦さを確保してボールがスムー スに転がって回収できるようにし、打球が打球方向とは異なった方に跳ね返るこ とを大幅に少なくしたり又は皆無とした被いで凹所内の映写手段を防護する投球 装置を提供することを目的としている。The present invention has been devised in view of the above-mentioned conventional circumstances, and a ball is smoothly provided by ensuring the flatness of an inclined surface between a bat and a screen so that a batter does not feel uncomfortable. An object of the present invention is to provide a pitching device that enables the ball to be rolled and collected, greatly reduces the possibility that the hit ball rebounds in a direction different from the hitting direction, or protects the projection means in the recess with a cover that has no shot. .

上記の目的を達成するために本考案の請求項１に係る投球装置は、投球マシン に隣接して立設された映写スクリーンから投球方向前方に離れて打席が設けられ 、該打席側から上記映写スクリーン側に向かって下がる傾斜面に形成された凹所 内に、投映部を上記映写スクリーンに向けた状態で設置された映写手段によって 上記映写スクリーンにピッチャー等の投球者の投球フォームを映写するようにし たものにおいて、上記凹所は、上記映写手段の投映部からの投映光線が通る部分 に透光部を有し上記映写手段をボール対して保護する被い手段で覆われており、 該被い手段は、上記傾斜面より上方に突き出ないように且つ上記傾斜面の傾斜方 向に傾斜して上記凹所内に設置されていることを特徴としている。 In order to achieve the above object, a pitching apparatus according to claim 1 of the present invention is provided with a bat at a distance from a projection screen erected adjacent to a pitching machine in a forward direction in a pitching direction. In a recess formed on an inclined surface that descends toward the screen side, a projecting unit installed with the projection unit facing the projection screen is used to project the pitcher's pitch form such as a pitcher onto the projection screen. In the above structure, the recess is covered with a covering means having a light-transmitting portion at a portion where the projection light beam from the projection section of the projection means passes and protecting the projection means against a ball. The means is installed in the recess so as not to protrude above the inclined surface and inclining in the direction of inclination of the inclined surface.

Because it is housed in the recess, there is no protrusion on the inclined surface and it is flat, and the batter does not feel uncomfortable with the projection means and covering means, and the hitting ball hits the projection means and the covering. It is less likely to bounce in a direction different from the hitting direction. The projection means in the recess is protected from the hit ball by the protective covering means, so that the occurrence of failure due to the hit ball is prevented and the service life is prolonged.
【０００８】 また被い手段の上面が、傾斜面の傾斜方向に傾斜しているために、映写スクリ ーン側に下るように傾斜した床面や地面に沿って転がって来るボールは、被い手 段上で止まることがなく、スムースにボールは回収され得る。被い手段は、投映 光線が通る部分のみに透光部を設けるか、全体的に透光部として凹所を完全に塞 いで映写手段を保護するか、又は部分的に塞いで映写手段を保護すればよく、更 に凹所内に傾斜面と共面状態で、又は傾斜面より低く設置されればよく、景観上 、またボール回収上色々な対応がとれる。Further, since the upper surface of the covering means is inclined in the direction of inclination of the inclined surface, the ball rolling along the floor or the ground inclined downward to the projection screen side is not covered. The ball can be collected smoothly without stopping on the means. The covering means should be provided with a light-transmitting part only at the part where the projected light passes, protect the projecting means by completely closing the recess as a whole light-transmitting part, or protect the projecting means by partially covering it. It may be installed in the recess coplanar with the inclined surface or lower than the inclined surface, and various measures can be taken in terms of landscape and ball collection.

Also, since the upper surface of the covering means is inclined in the direction of the inclined surface, balls rolling along the floor or ground inclined down to the projection screen side must stop on the covering means. There is no ball and the ball is collected smoothly. The covering means may be provided with a light-transmitting part only at the part where the projected light beam passes, or the light-transmitting part may completely cover the recess to protect the projecting means. The collection structure is simplified.
