Description

  The present invention relates to a batting practice device used for practicing martial arts such as karate and boxing.

Recently, watching sports via video and audio transmission means such as television and the Internet has become fond of love, and karate, boxing, kick boxing and other martial arts are especially popular among young people. Such martial arts sports are popular not only for watching sports but also for sports competitions, and the number of competition sports is quite large when women and women are engaged in health maintenance. By the way, among those competitions, in full contact tolerance competitions that allow direct contact with the opponent's body, it is difficult to practice under the same conditions as the actual battle that always faces the opponent, Because of the necessity of self-practice, for example, a batting practice is usually performed using, for example, a sandbag as a virtual opponent. The sandbag is literally a sandbag, which is placed in front of the practitioner and performs a batting practice with the upper or lower limbs. As a method of supporting the sandbag, for example, a method of hanging and supporting on a building beam or a tree, or a method of attaching to a stand placed on the ground is used in Japanese Utility Model Laid-Open No. 5-24073 and utility model registration No. 3054652 ,Proposed.

  Patent Document 1 discloses a sandbag stand that suspends a sandbag through a suspension 11 that is suspended from a support column 5 that is erected on a support base 1. In the sandbag stand of Patent Document 1, a horizontal bar 8 is projected in a horizontal direction from an upper end of an upright column 5 and a sandbag A is suspended from a front end of the support 5 via a suspension 11. For this reason, since the weight load of the sandbag A is applied downward from the front end side of the reed 8, for example, a heavy load of about 100 kg is supported, and the impact of several hundred kilograms applied to the bag is repeated. It must be a support structure that can withstand receiving. That is, in order to receive a striking force during striking practice and maintain the structure as a structure, it is necessary to be able to withstand the striking with a weight filled with a sufficient amount of sand. Therefore, in the apparatus of this patent document 1, the connection part of the support | pillar 5 and the recumbency 8 tends to be broken, and was dangerous. In addition, there is a problem that the support portion for strengthening the support of the connecting portion is increased in size and weight, and the entire apparatus cannot be easily installed and moved. In addition, when the device is moved and installed, the barbell plate to be inserted and mounted on the pin 19 is removed for stabilization of the support base 1 and the work of re-installation after installation and the management of the plate are complicated and heavy labor is required. Met. In addition, the hanging sand bag cannot be attached to the reed 8 unless the bag is once lifted and supported after the sand is filled into the bag, and more than one person is required for the setup work. There was a problem that it took a lot of labor and time. Further, in the stand-type sand bag of Patent Document 2, one support column 2 is set up at the center of the weight tank 3, and the support column 2 is inserted into a vertical hole of the bag body 1 to support the bag body 1 in a sudden manner. It is something to be made. However, since the apparatus of Patent Document 2 requires a support column to be erected at the center portion of the weight tank, the weight tank is used so as not to obstruct the standing position when hitting the bag body with the upper limb or the lower limb. 3 is required to be small to some extent so as not to be bulky in the lateral direction. For this reason, when a large striking force is applied due to lack of stability, the entire device is largely swung together with this tank, and a professional fighter performs. It could not be put to practical use in full-scale batting practice. Further, as described above, since one support column is erected at the central portion of the weight tank, the support position of the bag body 1 cannot be decentered or the support structure cannot be made impossible to maintain strength. Therefore, there is a problem that the base 10 is always larger than the outer contour of the bag body, and for example, a drastic kicking operation or driving operation cannot be performed. Further, since the weight tank 3 is a single integral container because it is supported by the center, it is inconvenient and bulky at the time of transporting movement, etc., and it is inconvenient to attach and remove the bag body to the column. .

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. FIGS. 1 to 9 show an embodiment of the present invention. In FIG. 1, the batting practice apparatus 10 of the present embodiment includes a base portion 12, a support post 14, a mitt body 16, and an allowable body. And a portable container device 18. 1 to 3, the base portion 12 is a supporting base means for stably and firmly supporting the mitt body 16 in a standing state. In this embodiment, for example, a metal pipe frame is fixed by welding to form a circular frame shape. It is configured. The metal pipe frame may be made of iron or stainless steel, but is made of an aluminum pipe for weight reduction. Specifically, the base portion 12 is formed by welding and fixing a circular frame 121 and two parallel frames 122 that are spanned and fixed in parallel to the inside of the circular frame 121.

  The support post 14 is a support means that is supported by the base portion 12 and supports the striking mitt body in a vertically long shape. In this embodiment, as shown in FIGS. Are joined and fixed together. That is, the support post 14 of the present embodiment is integrally joined using the same material as the base portion 12. The support post 14 includes two columns 141 that are connected and fixed to each other by a plurality of connecting rods 140 and arranged in parallel in the vertical direction. As shown in FIGS. 2 and 7, the two support columns 141 are supported in an upright manner via leg portions 20 that rise while the base side is connected and fixed to the base portion 12. Specifically, the base of the leg portion 20 is joined to a frame portion at a position 180 degrees apart from both ends of one diameter line of the circular frame 121 and a position 90 degrees away from each of them. Three leg rods 201 that stand up, and a horizontal rod 202 that is jointly fixed to all upper ends of the leg rods 201 are included. Then, both ends of the horizontal rod 202 are joined and fixed to the L-shaped connecting rod 142 on the lower end side of the two columns 141, whereby the base portion and the support post are integrally joined. These are all assembled by joining metal pipe frames, but the base part of the leg part 20 and the base part 12 have a strong support structure by three-point joining, and two are connected via a horizontal rod 202. The column 141 is raised up without difficulty and fixed. These leg portions 20 are fixedly supported by the base portion 12 so as not to exist immediately below the attachment position of the mitt body 16. In the embodiment, each of the three leg rods 201 is fixed to the circular frame at a range of about 180 degrees of the circular frame 121, is obliquely raised and fixed toward the center side, and is further connected via an L-shaped connecting rod 142. Further, the position is set at a position deviated to the remaining 180 degree range. Therefore, when kicking and hitting the lower position of the mitt body with a kick or the like, the hitting practice can be performed without hitting a metal frame such as a leg or a support post directly. As shown in FIGS. 2 and 3, the two columns 141 are formed upright in the vicinity of the outer edge portion of the base portion 12 via the L-shaped connecting rod 142.

  1, 3, 4, and 8, the base portion 12 forms a stable placement receiving portion 24 for stably placing a weight tool 22 described later on the upper surface. In the present embodiment, the stable placement receiving portion 24 is the entire upper surface formed by the circular frame and the pipe frame of the parallel frames 121 and 122, and the weight tool is freely and stably disposed using the entire upper surface. Therefore, the assembling work is simple and the working efficiency is very good. Further, the weight support weight can be received by the entire frame of the base portion, and the support post can be surely and stably supported in an upright and immobile state.

  The mitt body 16 is a striking practice mitt body that is mounted on the support post 14 and is supported upright and directly receives a blow by the practitioner's upper limb or lower limb. It is composed of a lightweight vertical hollow cylinder covered with a durable tent fabric. Since the mitt body 16 is light in weight as described above, the base portion 12 is provided with a wide range of stable placement receiving portions 24 and is supported by the entire surface of the base portion via a portable container device to be described later. Even if striking force is applied, there is no lifting of the base part, so you can practice stably. The mitt body 16 may be a conventional sand bag in which sand is filled. In addition, it may be stuffed with old cloth, corrugated paper, paper, bag, synthetic resin chip, synthetic resin piece, a combination of a plurality of them, or any other material. More specifically, in the present embodiment, a material having elasticity to some extent in which urethane sponge and foamed polyethylene are mixed is packed inside, and the outer skin portion is covered with a tent cloth such as Tetron or Vinylon.

  In this embodiment, a longitudinally elongated hole 161 into which a plurality of support posts 141 of the support post 14 are inserted is formed in the inner central portion of the mitt body 16 as shown in FIGS. Has been. In the present embodiment, as shown in the figure, the vertically long hole 161 is formed in a long hole LH shape in which either one is longer in cross section. Therefore, by inserting the support pillars 141 standing upright and parallel to the inner end portions of the long hole LH, the mounting position of the support pillar 141 can be easily set in the longitudinally long hole 161 even if the mitt body 16 is hit from the outside. There is no deviation. In order to prevent displacement of the mounting position of the support 141 with respect to the mitt body 16, not only the shape of the long hole in the cross section but also an arbitrary hole shape can be selected according to the number of the support 141 to be erected. For example, it is good also as a hole structure in which a support | pillar position is a triangle in a cross section, a parallelogram, other arbitrary polygons, or its deformation | transformation aspect. Each of the holes may be an independent hole, but from the viewpoint of workability when inserted into the mitt body, it is preferable that the holes communicate with each other in cross section. In the present embodiment, the mitt body 16 is a cylindrical body having an elliptical cross section. By providing a long hole with a long hole shape, it is possible to easily attach / detach the mitt body to the support 141 from the front, and the like. This is convenient for cargo stability. In addition, the outer shell shape of the mitt body 16 is not limited to an elliptical shape, and may be arbitrarily set such as a perfect circle shape or a polygonal shape with a corner dropped.

  Further, the hitting practice mitt body 16 is provided with a vertically long notch 162 communicating with the vertically long hole 161 in a vertically long shape. The vertically long notch 162 is a communication gap for mounting and attaching the support post 14 to the vertically long hole 161 so as to be detachable from the lateral direction, and is formed over the entire length of the mitt body 16 in the embodiment. For example, in order to insert the mitt body 16 into two struts 141, as shown in FIG. 6, the mitt body 16 itself is elastically bent. The support post 141 can be easily inserted into the vertically elongated hole 161. After the insertion, as shown in FIG. 2 again, the support post 141 is brought into close contact with both inner end portions of the cross-sectional elongated hole of the vertically long hole, and the engagement position between the support column and the mitt body is determined to prevent displacement. In particular, in the present embodiment, since the vertically long notch groove 162 is provided on the opposite long side of the long hole shape, it is easy to insert the column 141 from the lateral direction in an upright state. It can be carried out in a short time and can be stably arranged and the mounting position can be fixed so that a portion having no vertically long groove is desired on the side facing the practitioner. As shown in FIG. 4, in the present embodiment, in the state in which the two struts 141 are inserted into the vertically elongated holes 161 of the mitt body 16, the connecting rod 140 arranged in the lateral direction that connects the two struts is attached. A surface fastener member 163 supported at one end is provided in the longitudinal elongated hole 161 of the mitt body so as to be wound respectively. After the mitt body is inserted from the lateral direction, the mast body is locked by the surface fastener member and is supported by the support post 141.

And the weight tool 22 is comprised from the several portable container apparatus 18 which accommodates the weight body 221 so that refilling is possible. In this way, even if a plurality of portable container devices 18 are placed on the stable placement receiving portion 24 of the base portion 12 so as to apply an equal load, the entire base portion is loaded and a striking action is applied. The body 16 can be stably supported upright. Furthermore, by transporting only the container of the portable container device and packing it with a filler such as sand on the site where it is assembled, it can be easily distributed as a product, and is convenient for the user. In particular, in this embodiment, the portable container device is made of a bag body 224 with a handle 223 made of a flexible and foldable material that is filled with sand, so that it can be folded compactly without being bulky. Almost no burden. Therefore, compared with a container made of synthetic resin or the like, the cost for molding is unnecessary, and manufacturing at low cost is possible. Further, for example, sand can be accommodated in the bag body 224 and placed on the stable placement receiving portion 24 of the base portion 12, so that the load can be supported, the assembly of the device is easy, and the assembly time can be reduced in an extremely short time. . Therefore, it can be easily moved to practice other than the usual practice areas such as training camps and expeditions. In the present embodiment, the bag bodies 224 are each formed in a three-dimensional sector shape, and four of them are arranged in close contact with each other along the outer circumference of the circular frame 121 so as to be in close contact with each other. In addition, the load support of the mitts 14 and 16 is reliably performed. As shown in the figure, each portable container device is in close contact with each other to form one integral base part, and the upper mitt body is arranged so that the upper surface thereof is almost in contact with each other. A gap is not formed between the respective portable container devices and between them and the mitt body on the surface to be hit. As a result, the practitioner can be safely put into practice without causing the practitioner to get injured by putting his / her foot in the practice of striking the foot. In FIG. 9, reference numeral 225 denotes a fastener portion that closes the housing body 226 and the opening / closing lid 227 of the bag body 224 so as to be freely opened and closed.
