[Embodiment of the invention]

 Hereinafter, the present invention will be described based on an embodiment, but the present invention is not limited to this embodiment.

As shown in FIGS. 1 and 2, the batting tee includes members such as a bottom frame 10, a support rod 20, and a support rod 24.

The bottom frame 10 is formed by bending an elastic metal rod 11 into a triangular shape similar to a home plate, and has relatively excellent gripping and stability with respect to the ground. Extension lines (indicated by dashed lines in FIG. 1) of the frame members 10a and 10b corresponding to both hypotenuses of the triangle of the bottom frame 10 coincide with the first and third base foul lines when the bottom frame 10 is assumed to be a home base. As a result, the size of the inner angle θ of the frame members 10a and 10b is set, so that the trainee can feel the direction in which the ball flies, and effective training becomes possible.

The ends of the frame members 10 a and 10 b at the apex of the bottom frame 10 are separated from each other, and a pivot seat 12 is provided at the apex. The pivot seat 12 includes a pair of disk-shaped holding plates 121 disposed opposite to each other, and inside each of the holding plates 121 is formed an arc-shaped concave vertical groove 122. On the sides, through holes 123 are respectively formed, and the holding plates 121 are fixed to the ends of the frame members 10a and 10b, respectively. In addition, a concave portion 13 that is concave upward is formed at the center of the connection frame member 10c corresponding to both bottom sides of the triangle of the bottom frame 10.

The support rod 20 has a fixed rod 21 of a small-diameter pipe and a movable rod 22 of a large-diameter pipe. Inside the movable rod 22, a sliding hole 221 having both ends opened is formed. Is slidably inserted into the fixed rod 21 so that the height can be adjusted, and the movable rod 22 is held at an arbitrary height by holding means. A support rod 24 is connected to an upper end of the movable rod 22 via a flexible sleeve 23.

The lower end of the fixing rod 21 of the support rod 20 is elastically deformed by the metal rod 11 and fitted into the vertical groove 122 of the both holding plates 121 so that the lower end of the fixing rod 21 is elastically held by the two holding plates 121. Thus, the support rod 20 stands upright from the bottom frame 10. A fastening hole 211 is formed at the lower end of the fixed rod 21, and the fastening pin 212 is passed through the fastening hole 211 and the through hole 123 of the holding plate 121 to pivotally fix the fixed rod 21 to the pivot seat 12. Thus, the fixed rod 21 can rotate between the two holding plates 121 of the pivot seat 12.

The holding means is configured as follows. An enlarged tube 213 is attached to the upper end of the fixed rod 21 via a bush, and a cut groove 213 is formed downward from the upper end surface of the enlarged tube 213, and a V-shape is formed in the cut groove 213 '. The elastic member 215 is inserted and the tightening rod 214 is inserted into the horizontal hole 213 a provided at the upper end of the fixed rod 21, and the elastic member 215 is held by the tightening rod 214 and the elastic member 215 is pulled out. Is prevented. The elastic member 215 includes both holding legs 216, and a free end portion of each holding leg 216 is outwardly curved in a “C” shape to form a projecting and expanding portion 217. The maximum width between the projecting and expanding portions 217 of both holding legs 216 of the elastic member 215 is set to be larger than the outer diameter of the fixed rod 21 and the diameter of the sliding hole 221 of the movable rod 22. Then, the projecting and expanding portion 217 of the elastic member 215 is brought into elastic contact with the inner peripheral surface of the sliding hole 221 of the movable rod 22 to frictionally engage the movable rod 22 with the elastic member 215. It is designed to hold at an arbitrary height. By using the holding means configured as described above, the movable rod 22 can be held at an arbitrary height without performing a holding operation.

When the movable rod 22 is lowered to the lowest position, the projecting and expanding portion 217 of the elastic member 215 engages with the ring-shaped groove 223 of the movable rod 22.

At the lower end of the movable rod 22, there is provided a throttle part 222 in which the diameter of the sliding hole 221 gradually decreases as going downward, and the minimum hole diameter of the throttle part 222 is smaller than the outer diameter of the enlarged pipe 213 of the fixed rod 21. Thus, the expansion tube 213 is restricted inside the sliding hole 221.

A ring-shaped groove 223 is formed at the upper end of the sliding hole 221 of the movable rod 22, and the diameter of the bottom of the ring-shaped groove 223 is made larger than the inner diameter of the sliding hole 221 so that the ring-shaped groove 223 is formed. The projecting and expanding portion 217 of the elastic member 215 is held. Further, a convex ring 224 is protruded from a portion of the outer peripheral surface of the upper end of the movable rod 22 corresponding to the ring-shaped groove 223.

A support rod 24 is connected to an upper end of the movable rod 22 via a flexible sleeve 23. A flange 241 is formed at a lower end of the support rod 24. The flexible sleeve 23 is formed in a bellows-like shape, and a plurality of annular grooves 231 are arranged in the inside thereof in the axial direction. The lowermost annular groove 231 ′ is detachable from the convex ring 224 of the movable rod 22. The uppermost annular groove 231 ″ is detachably fitted to the flange 241 at the lower end of the support rod 24.

A trumpet-shaped fixing portion 242 is formed at an upper end portion of the support rod 24 so that the ball 100 can be stably mounted.

As shown in FIG. 3, when assembling the batting tee, first, an enlarged pipe 213 is attached to the upper end of the fixed rod 21, and the elastic member 215 is restricted in the cut groove 213 ′ by the tightening rod 214. Next, the lower end of the fixed rod 21 is fitted into the upper end of the sliding hole 221 of the movable rod 22 so that the lower end of the fixed rod 21 protrudes from the throttle portion 222 of the movable rod 22. By pressing both holding legs 216 inward, the elastic member 215 is inserted into the sliding hole 221 of the movable rod 22. In the sliding hole 221, both holding legs 216 of the elastic member 215 are elastically urged outward and come into contact with the inner peripheral surface of the movable rod 22. Subsequently, the lower end of the fixed rod 21 is inserted into the pivot seat 12, and the lower end of the fixed rod 21 is fitted into the vertical groove 122, so that the fixed rod 21 is firmly held by the two holding plates 121, and Are erected from the triangular top of the bottom frame 10. Further, the fastening pin 212 is inserted into the through-hole 123 of both the holding plates 121 and the fastening hole 211 of the fixed rod 21 to pivotally fix the fixed rod 21 to the pivot seat 12.

Thereafter, the lower end of the flexible sleeve 23 is externally fitted to the upper end of the movable rod 22, and the convex ring 224 of the movable rod 22 is fitted in the annular groove 231 ′ of the flexible sleeve 23 to flexibly. The flexible sleeve 23 and the movable rod 22 are connected, and the flange 241 at the lower end of the support rod 24 is fitted into the annular groove 231 ″ of the flexible sleeve 23 to connect the support rod 24 and the flexible sleeve 23. When the ball 100 is placed on the fixing portion 242 of the support rod 24, the batting tee can be practiced.

FIG. 3 shows a state in which the movable rod 22 is slid upward and the enlarged rod 13 approaches the narrowed portion 222, and the ball is positioned at the highest position. In this state, there is a person whose height is relatively high. Applies to practice when the hit point is relatively high. When the height of the support rod 20 is to be reduced, FIG. 4 shows that the movable rod 22 is pulled down against the frictional engagement force of the elastic member 215 to reduce the overall length of the support rod 20 and place the ball 100 thereon. This shows a state where the height is lowered. In the state shown in FIG. 3 and FIG. 4, both holding legs 216 of the elastic member 215 hold the movable rod 22 by using the force of elastically stretching outward, and the movable rod 22 is not in use during the exercise. It doesn't slide easily.

When folded without being stored or used for a while, as shown in FIGS. 5 and 6, the movable rod 22 is moved downward (toward the lower end of the fixed rod 21) by operating the movable rod 22, and the ring of the movable rod 22 is moved. When the groove 223 and the elastic member 215 are at the same level, the projecting and expanding portion 217 of the elastic member 215 is fitted and held in the ring-shaped groove 223, the support rod 20 becomes the shortest dimension, and the movable rod is formed. 22 can be prevented from inadvertently sliding the fixed rod 21 to extend the support rod 20. Subsequently, as shown by an arrow in FIG. 5, when the entire support rod 20 is rotated, the support rod 20 and the bottom frame 10 overlap as shown in FIG. 13 and the folding is complete. Further, when the flexible sleeve 23 and the support rod 24 are removed from the movable rod 22, the storage space can be further reduced, and the convenience of packaging and storage can be improved.

Then, when deploying and standing up again for hitting practice, the support rod 20 is rotated in the opposite direction to the above operation, the support rod 20 is erected from the bottom frame 10, and the movable rod 22 is turned upward. By forcibly pushing up, the projecting and expanding portion 217 of the elastic member 215 is detached from the ring-shaped groove 223, and the projecting and expanding portion 217 of the elastic member 215 is moved around the inner periphery of the sliding hole 221 of the movable rod 22. By sliding along the surface, the length of the support rod 20 can be extended to an appropriate height and applied to a hitting practice.

[Effect of the invention]

 As described above, the present invention can solve the drawbacks of using conventional batting tees. In other words, the movable rod can be moved up and down with respect to the fixed rod and held at an arbitrary height, so that the ball can be practiced by changing the height of the ball. It can be applied to children of various ages. You can also practice hit points at different heights.

Further, since the support rod is connected to the upper end of the movable rod via a flexible sleeve, even if the bat hits the support rod, the shock is transmitted directly to the support rod by the buffering action of the flexible sleeve. Can be prevented, and the batting tee can be prevented from falling over or being damaged.

Further, the flexible sleeve is formed in a bellows-like tubular shape, and the innermost annular groove at the lowermost end of the flexible sleeve is fitted to the convex ring of the movable rod. Since the innermost annular groove at the uppermost end of the sleeve is fitted to the flange of the support rod, assembly using the bellows tube shape of the flexible sleeve can be performed, and the manufacturing cost can be reduced.

Further, since the holding means is configured as described above, an operation for holding is unnecessary, and the height adjustment of the movable rod is facilitated.

Further, the bottom frame is formed in a triangular shape approximating the shape of a home plate, a corner of the bottom frame is connected to a lower end of the fixed rod of the support rod, and a pair of extending from the corner is formed. The angle between the frame members is set to be approximately the same as the angle between the foul lines extending from the home base, so that during the practice of hitting, the trainee can feel the hitting position and hitting direction of the home plate, etc. It is possible to approach the state when approaching.

Also, since the bottom frame extends from the lower end of the support rod in the direction in which the bat is swung, even if the bat hits the support rod or the like and the support rod falls down, it can effectively resist this, and practice hitting. It is difficult for the batting tee to fall down.

Further, the lower end of the support rod is rotatably connected to the one corner of the bottom frame by a connecting means, and the support rod is rotated so that the support rod is overlapped with the bottom frame so as to be folded. When not in use, it is not bulky, the storage space is small and storage and transportation are convenient, and when it is used again, the support rod can be rotated to its original upright state, so the operation is simple. It becomes very easy.

In addition, a concave portion that is concave upward is formed at an intermediate portion of the connection frame member that connects the pair of frame members of the bottom frame, and the support rod is located in the concave portion when folded. , The folded shape can be further reduced.
