  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an overall view of an embodiment of a ball game hitting practice device 1 according to the present invention, FIG. 2 is a longitudinal sectional view of a first embodiment showing a ball mounting portion 11 in a developed view, and FIG. 4 is the same embodiment. FIG. First, a first embodiment of a ball game hitting training device 1 according to the present invention will be described below.

  As shown in FIG. 1, the ball hitting training device 1 includes a plate 2, a support column that is erected on the plate 2 via a mounting plate 3, and a ball placement unit that is provided at the upper edge of the support column. 11. In this embodiment, the column portion includes a hollow cylindrical first column 4, a second column 7 that is coupled to the first column 4 via the first coupling member 6 and slides inside the first column 4. The third support 10 is connected to the second support 7 through the second connecting member 9 and slides inside the second support 7.

  The plate 2 is in contact with the ground and supports the entire ball game strike training device 1. The material of the plate 2 is not particularly limited, but may be rubber, resin, veneer plywood or the like. The overall shape of the plate 2 can be a pentagon having the same shape as a home plate used in baseball or a quadrangle with dimensions close to it, and the dimensions are used to release the impact when an excessive impact is applied. It is preferable to set the ball game hitting training device 1 to the extent that it is possible to fall down.

  When the plate 2 is a quadrangle, a mounting plate 3 made of a metal or a resin having sufficient rigidity is attached to the center, and in the case of a home plate-shaped pentagon, to the center or somewhat behind the weight distribution. As shown in FIG. 2, a mounting hole 3 a that can receive the first support column 4 is provided in the center of the mounting plate 3. The mounting hole 3 a has a female screw inside, and is screwed with a male screw provided at the lower edge portion of the first support column 4. The formation range of the female screw can be deepened by providing a portion that is larger than the thickness of the mounting plate 3 at the circumferential edge of the mounting hole 3a. The mounting plate 3 has screw holes at appropriate positions and is fixed to the plate 2 with screws.

  The first support column 4 is a hollow cylindrical member made of metal or resin having sufficient rigidity, and a male screw provided on the outer peripheral portion of the lower edge is screwed with a female screw provided in the mounting hole 3 a of the mounting plate 3. By doing so, it is erected on the plate 2. A first washer 5 is fitted from the upper end of the first support column 4. The first washer 5 has a flange portion 5a hooked on the upper end portion of the first support column 4 and an extension portion 5b extending downward along the inner surface of the first support column 4, and is vertically slit from the flange portion 5a to the extension portion 5b ( (Not shown) is provided, and the extension portion is provided below the split washer.

  A rubber first connecting member 6 having a lower opening 6 a is fitted so as to cover the upper edge portion of the first support column 4 and the first washer 5. The lower opening 6 a has an inner diameter that is slightly larger than the diameter of the first support column 4, and has a plurality of protrusions 6 b that rise in an annular shape on the inner wall. The protruding portion 6b is in contact with the outer peripheral portion of the upper edge of the first support column 4 so that the first connecting member 6 is not easily removed. The entire first connecting member 6 has a cylindrical shape, but the upper portion is enlarged in diameter and is thick, and the flange portion 5a of the first washer 5 that touches the upper portion in the lower opening 6a is tightened. As a result, the space between the vertical slits provided in the first washer 5 is narrowed. Moreover, the 1st connection member 6 also has the upper opening 6c, and the 2nd support | pillar 7 is penetrated here.

  The second support column 7 is a hollow cylindrical member made of a metal or a resin having sufficient rigidity, like the first support column 4, and is inserted into the upper opening 6 c of the first connection member 6 and the center of the first washer 5. The first support 4 is housed inside. At this time, the first washer extension portion 5 b is interposed between the inner wall of the first support column 4 and the outer wall of the second support column 7. The second strut 7 is given moderate friction (due to tightening of the flange 5a) due to contact with the upper opening 6c of the first connecting member 6 and contact with the inner wall of the first washer extension 5b. Therefore, an appropriate vertical operation of the second support 7 can be performed manually by the user. Further, the material of the second support column 7 is not limited, but if the sleeve 7a is provided, the gap between the outer wall of the second support column 7 and the inner wall of the first support column 4 can be reduced. Less movement.

  A second washer 8 is fitted from the upper end of the second support column 7. The second washer 8 has a flange portion 8a hooked on the upper end portion of the second support column 7, and an extension portion 8b extending downward along the inner surface of the second support column 7. A slit is vertically formed from the flange portion 8a to the extension portion 8b. The provided structure is the same as that of the first washer 5 except for the dimensions. A rubber second connecting member 9 having a lower opening 9 a is fitted so as to cover the upper edge portion of the second support column 7 and the second washer 8. The configuration of the second connecting member 9 is the same as that of the first connecting member 6 except for the dimensions. The second connecting member 9 also has an upper opening 9c, through which the third support column 10 is inserted.

  The third support column 10 is a hollow cylindrical member made of metal or resin having sufficient rigidity, like the first support column 4 and the second support column 7, but the tip portion 10 b is a curved surface. The third column 10 is inserted through the upper opening 9 c of the second connecting member 9 and the center of the second washer 8 and is housed inside the second column 7. At this time, the second washer extension portion 8b is interposed between the inner wall of the second column 7 and the outer wall of the third column 10. Appropriate friction (contact with the upper part in the lower opening 9a of the second connecting member 9) is made on the third support column 10 due to the contact with the upper opening 9c of the second connecting member 9 and the inner wall of the second washer extension 8b. The second washer collar 8a is tightened). Therefore, an appropriate vertical operation of the third support column 10 can be performed manually by the user. Furthermore, when the sleeve 10a is provided below the third support column 10, the gap between the outer wall of the third support column 10 and the inner wall of the second support column 7 can be further reduced, and the swing of the third support column 10 is reduced.

  A rubber cover 11 d is prepared above the second washer 8 in the third support column 10. As will be described later, after the ball mounting portion 11 is formed, the lower portion of the ball mounting portion 11 and the connecting portion between the third support columns 10 are covered and fixed.

  The ball placing portion 11 is for placing the ball 12 on the upper portion, and is provided from the front portion where the curved surface of the tip portion 10b of the third support column 10 is formed as shown in FIG. The ball mounting portion 11 is made of a fan-shaped sheet-like flexible material 11g made of rubber or cloth. In order to immediately return to the original shape after being hit by a bat, rubber is used. It is desirable to be made.

  The sheet-like flexible material 11g is wound so as to have a substantially conical shape whose diameter is expanded upward, and a double-sided tape 11b is adhered and fixed to a contact portion with the upper edge portion of the third support column 10. At that time, if the ball mounting portion 11 is formed so that the sheet-like flexible material 11g overlaps several times, the mounting area of the ball 12 becomes too small to stably hold the ball 12. May become difficult, or the flexibility of the ball mounting portion 11 itself may be impaired. The ball mounting portion 11 is preferably formed by winding the sheet-like flexible material 11g from single to double.

  Next, a fixing means 11 c such as a tape is wound around the lower edge of the ball mounting portion 11 and the boundary portion with the third support column 10. If it does in this way, coupled with the fixing force of the double-sided tape 11b stuck inside the sheet-like flexible material 11g, the ball mounting part 11 will accidentally slide off from the third support column 10 or continue. The situation that it becomes easy to come off by the hitting is reduced.

  Next, the rubber cover 11d prepared by inserting the third support column 10 in advance is put on the fixing means 11c such as a tape connected to the third support column 10 and the sheet-like flexible material 11g. It is preferable that the rubber cover 11d has a size and elasticity that sufficiently tightens a portion where the sheet-like flexible material 11g and the third support column 10 are integrated to give a fixing force. If it does so, the stability with respect to rocking | fluctuation in the state in which the sheet-like flexible material 11g wound around the 3rd support | pillar 10 can be strengthened.

  In the present embodiment, since the upper edge portion of the ball mounting portion 11 is a free end, the impact due to impact is easy to escape while maintaining the support force for the ball 12. Moreover, the rounding process is given to the upper edge corner | angular part of the last end 11a when the sheet-like flexible material 11g is wound. Thereby, even when the upper edge portion of the ball mounting portion 11 is a free end, the amount of the final end 11a of the sheet-like flexible material 11g greatly protruding from the ball mounting portion 11 to the outside is small. Thus, it is possible to reduce the contact of the bat with the ball mounting portion 11 more than necessary at the time of hitting.

  Further, the curved surface of the tip portion 10b of the third support column 10 is a situation where the ball mounting portion 11 is swung back and forth and left and right by continuous striking and the inside of the ball mounting portion 11 touches the tip portion 10b violently. However, it is difficult to damage the inside of the ball mounting portion 11.

  As a result, the life of the ball mounting portion 11 can be extended. If damage to the ball mounting portion 11 has progressed due to long-term use of the ball game hitting practice device 1, only a new sheet-like flexible material 11g portion should be prepared and fixed again using tape or the like. Simple and inexpensive replacement is possible.

  In the first embodiment described above, the first connection member 6 is connected to the connection portion between the first support column 4 and the second support column 7, and the second connection member 9 is connected to the connection portion of the second support column 7 and the third support column 10. The thing using was explained. Here, at a position corresponding to the first connecting member 6, a known sleeve nut 13 shown in FIG. 3A, a tightening knob 14 shown in FIG. The height of the second column 7 is fixed, and a rubber connecting member is used only between the second column 7 and the third column 10 so that the height of the third column 10 can be easily changed manually. It may be configured to. In the first embodiment, the three-stage expansion / contraction configuration composed of the first support column 4, the second support column 7, and the third support column 10 has been described. Alternatively, as a cheaper product, a two-stage expansion / contraction configuration can be used as shown in FIG.

  Next, a second embodiment according to the present invention will be described. The basic configuration of the second embodiment is the same as that of the first embodiment. However, as shown in FIG. 5, a tapered portion 10c whose diameter is increased upward is provided at the tip of the third support column 10, and the tapered portion 10c. A curved surface portion 10d is formed from the largest diameter portion to the front end of the column portion. The taper portion 10c is an inclined surface for guiding so that the sheet-like flexible material 11g is wound so as to become the substantially conical ball mounting portion 11, and the sheet-like flexible material 11g is wound more stably. It is turned on. The curved surface portion 10d formed from the maximum diameter portion of the taper portion 10c to the front end portion of the column portion can disperse the burden on the inside of the ball mounting portion 11. The gentler the curved surface portion 10d, the longer the life of the ball mounting portion 11 can be.

  A third embodiment according to the present invention will be described. The basic configuration of the third embodiment is the same as that of the first embodiment, but, as shown in FIG. 6, the diameter is increased upward at the tip of the third support column 10 as shown in the second embodiment. The formation of the tapered portion 10c is achieved by fitting the tapered cap 10e. The material of the taper cap 10e can be synthetic resin, metal, or the like.

  The effect by 3rd embodiment can anticipate the same effect as the content shown in 2nd embodiment. In terms of configuration, the taper cap 10e is fitted into a portion having the same shape as the tip end portion 10b of the third column in the first embodiment, and is simpler than the configuration of forming the taper portion 10c in the second embodiment. Sometimes it becomes. In this respect, the manufacturing process may be simplified and the manufacturing cost may be reduced.

  A fourth embodiment according to the present invention will be described. The basic configuration of the fourth embodiment is the same as that of the first embodiment, and the configuration of the second embodiment or the third embodiment can be used. However, as shown in FIG. A mounting saddle portion 11e protruding inward is provided on the upper edge portion of the property material 11g.

  In FIG. 7, the ball mounting portion 11 is formed by the sheet-like flexible material 11g provided with the mounting rod portion 11e, and the mounting rod portion 11e is formed so as to protrude inward from the upper end portion. It is shown. If the notch portions 11f are provided in the mounting rod portion 11e at regular intervals, the mounting rod portion 11e is likely to have an annular shape. If the annular mounting rod portion 11e is provided, even if the bat hits the periphery of the boundary between the ball 12 and the ball mounting portion 11, the bat can easily slide through the upper end portion of the ball mounting portion 11, There is an effect of further mitigating the impact on the entire ball mounting portion 11. Thereby, the lifetime of the ball mounting part 11 can be further extended.

  The effects of the ball game hitting practice device 1 of the present embodiment configured as described above will be described below. Since the ball mounting part 11 having a substantially conical shape whose diameter is expanded upward, which the ball game hitting training device 1 has, is formed by winding the sheet-like flexible material 11g around the upper edge of the support part, the operation is simple. Further, since the upper edge portion of the ball mounting portion 11 is a free end, it is easy to miss the impact due to impact while maintaining the supporting force for the ball 12. As a result, the life of the ball mounting portion 11 is extended.

  Further, since the rounding process is performed on the upper edge corner portion of the winding end 11a of the sheet-like flexible material 11g, the final end 11a of the sheet-like flexible material 11g is greatly outward from the ball mounting portion 11. The amount of protrusion is reduced, and useless contact between the bat and the ball placing portion 11 due to the hit is reduced. Thereby, the lifetime of the ball | bowl mounting part 11 becomes long.

  Moreover, the taper part 10c which expands upwards at the front-end | tip of the 3rd support | pillar 10, and the structure by which the curved-surface part 10d is formed in the front-end | tip direction from the largest diameter part of the taper part 10c can also be taken. Thereby, the taper part 10c becomes an inclined surface for guide for the sheet-like flexible material 11g to be formed in a substantially conical shape, and makes it easy to form the ball mounting part 11. Further, the ball mounting portion 11 provided at the tip of the support column is difficult to come off. Further, the curved surface portion 10d formed in the taper portion 10c in the tip end direction provides a wide contact area with respect to the inside of the ball mounting portion 11, and thus is less likely to damage the inside of the ball mounting portion 11. Thereby, the lifetime of the ball | bowl mounting part 11 becomes still longer.

  By fitting a taper cap 10e that expands upward into the tip portion 10b of the third support column 10, the same effect as that obtained by forming the taper portion 10c can be obtained. Thereby, the structure of the taper portion can be easily changed by the taper cap 10e, and the manufacturing cost is reduced.

  Even if the bat hits the vicinity of the boundary between the ball 12 and the ball mounting portion 11, the mounting rod portion 11 e formed so as to protrude inward from the upper end portion of the ball mounting portion 11 does not move the ball mounting portion 11. It will be easier to pass through the upper end of the arm, and the impact will be more relaxed.

  As described above, according to the present invention, a ball game hit which can extend the life of the ball mounting portion 11 with a very simple configuration and can be easily and inexpensively replaced. The training device 1 can be provided.

  It goes without saying that the specific configuration of each part of the present invention can be modified in various ways within the intended scope of the present invention. For example, as shown in FIG. 8, as a fifth embodiment, a ball game hitting training device 1 including a ball mounting portion 11 made of rubber or silicon that is integrally formed as a conical shape that expands upward in advance is configured. You can also In this way, when forming the ball mounting portion 11, the work of winding the sheet-like flexible material 11g around the third support column 10 can be omitted, and the fitting to the third support column 10 and the subsequent fixing means 11c can be omitted. There is no hassle in fixing work.

  As for the ball mounting part 11 which concerns on 5th embodiment, the upper edge part of the 3rd support | pillar 10 is inserted in the reduced diameter part of the downward direction. A double-sided tape 11b may be attached to the upper edge of the third support column 10. A fixing means 11c such as a tape is wound around a boundary portion between the ball mounting portion 11 and the third support column 10, and a rubber cover 11d prepared in advance for the third support column 10 is placed on the fixing means 11c. Such an attachment structure is the same as that shown in the first embodiment except for the work of winding.

  The ball mounting portion 11 according to the fifth embodiment is a third support column 10 as shown in FIG. 5, that is, a support column in which a curved surface portion 10d is formed from the tapered portion 10c and its maximum diameter portion to the support column tip direction. It is also possible to provide it at the tip. Moreover, it is also possible to provide at the front-end | tip of the support | pillar in which the taper cap 10e as shown in FIG. 6 was inserted. And as FIG. 9 shows, the ball mounting part 11 which concerns on 5th embodiment can also be formed with the mounting collar part 11e which protrudes inside from the upper end part. In that case, you may provide the notch part 11f in the mounting collar part 11e at fixed intervals. In addition, it is possible to maintain the supporting force while reducing the contact with the ball 12 as much as possible by processing the contact portion with the ball 12 at the upper end portion of the ball mounting portion 11 into a wave shape by upper and lower unevenness.
