Description

Technical Field

[0001] This invention relates to a sports training device, and more particularly to a simple tennis ball feeding device. Background Technology

[0002] Tennis is known as the world's second most popular ball sport and is loved by many. However, tennis cannot be learned in a day. To learn tennis, you first need to master the fundamentals of hitting the ball. Practicing the fundamentals requires a good sparring partner, but good sparring partners are generally hard to find or very expensive. Therefore, a common method is to use tennis training equipment, such as ball feeders.

[0003] Currently, the most commonly used tennis ball feeder is the two-wheel ball machine, which uses two high-speed rotating wheels in opposite directions to quickly spin the ball. This type of equipment helps beginners practice their basic skills to some extent.

[0004] However, this tennis ball feeding device has obvious drawbacks: its ball release position and rhythm are fixed, and it has only one outlet, making it only suitable for beginners to practice. It cannot improve the learner's ability to react quickly to different positions and rhythms. Moreover, the device has a complex structure, high price, and high operating costs.

[0005] In order to overcome the shortcomings of existing technology, the applicant has continuously conducted experiments and research, and finally developed a simple tennis ball feeding device. It can not only improve the player's ability to react quickly to different ball positions and rhythms, but also has a simple structure and low cost. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a simple tennis ball feeding device that can not only improve the player's ability to react quickly to different ball positions and rhythms, but also has a simple structure and low cost.

[0007] To solve the above-mentioned technical problems, the present invention provides a simple tennis ball feeding device, comprising a ball-holding container and a support; the ball-holding container is placed on the support; the bottom of the ball-holding container is provided with a ball outlet; a ball-dispensing device is connected to the bottom of the ball-holding container; the ball-dispensing device includes a turntable and a motor connected thereto, the turntable is movably connected to the bottom of the ball-holding container, a dispensing plate is provided on the outer edge of the turntable to dispensing the tennis ball from the ball outlet, and an anti-blocking protrusion is provided at the ball outlet on the inner wall of the ball-holding container; a ball-dispensing tube is connected below the ball outlet.

[0008] The ball container has two ball outlets at the bottom.

[0009] The bottom of the ball container is connected to a height adjustment rod; the height adjustment rod and the bracket are adjustablely connected via a gear and rack.

[0010] An adjustment gate is also provided below the ball outlet.

[0011] The ball outlet tube is a multi-section steerable tube.

[0012] The paddles are arranged in 8-12 equal intervals.

[0013] A ball release rhythm adjustment piece is movably connected above the outer edge of the turntable and the paddle; the ball release rhythm adjustment piece is staggered from the paddle and the same number of them are provided.

[0014] Five anti-blocking protrusions are arranged on the inner wall of the ball container corresponding to the ball outlet, wherein the anti-blocking protrusion in the middle is larger than the anti-blocking protrusions on both sides.

[0015] The inner wall of the ball container is provided with more than four blocking protrusions, and the distance between the blocking protrusions and the bottom of the ball container is greater than the distance between the anti-blocking protrusions and the bottom of the ball container.

[0016] The surfaces of the anti-blocking protrusion and the blocking protrusion are spherical; the surface of the blocking protrusion is spherical.

[0017] With the structure of this invention, the ball-dispensing device, due to the rotation of the turntable, causes the paddles on the outer edge of the turntable to move the tennis balls placed in the ball container. The anti-blocking protrusions on the inner wall of the ball container, in conjunction with the paddles, guide the tennis balls, allowing them to fall into the ball outlet and exit through the ball outlet tube below. This allows tennis players to practice basic hitting skills. Without the anti-blocking protrusions on the inner wall of the ball container, the paddles alone cannot smoothly move the tennis balls within the container.

[0018] The present invention preferably has two ball outlets, and the ball outlet tube is a multi-section steerable tube, which can make the tennis ball come out from two different positions according to the needs of practice, so as to improve the trainee's ability to react quickly to different ball outlet positions.

[0019] The present invention has a ball release rhythm adjustment plate movably connected above the paddle on the outer edge of the turntable. The ball release rhythm adjustment plate is staggered from the paddle and the same number of them are provided. The ball release rhythm adjustment plate can be hinged to the outer edge of the turntable. The ball release rhythm adjustment plate can be flipped up and down along the hinge. When the ball release rhythm adjustment plate is flipped up and rotated to the ball release opening position, the tennis ball falls into the ball release opening. When the ball release rhythm adjustment plate is flipped down and rotated to the ball release opening position, the tennis ball will not fall into the ball release opening. In this way, the rhythm of the tennis ball falling into the ball release opening can be adjusted, which can help improve the trainee's ability to react quickly to different ball release rhythms.

[0020] This invention features five anti-blocking protrusions arranged on the inner wall of the ball container at the ball outlet. The middle anti-blocking protrusion is larger than the two side anti-blocking protrusions. In this way, when the tennis ball in the ball container passes through the ball outlet under the action of the paddle, the anti-blocking protrusion pushes only one tennis ball into the ball outlet, which can prevent multiple tennis balls from falling into the ball outlet and causing blockage when the tennis ball in the ball container passes through the ball outlet under the action of the paddle. Moreover, the tennis ball can make a smooth transition when passing through the anti-blocking protrusion.

[0021] To ensure the tennis ball travels smoothly over the anti-blocking bumps, the surface of the bumps is spherical. This design facilitates manufacturing and reduces wear on the tennis ball. The spherical surface of the blocking bumps also facilitates manufacturing and reduces wear on the tennis ball.

[0022] In this invention, both the paddle and the ball release rhythm adjustment paddle are equidistantly arranged, preferably 8-12 paddles, which is the best choice for the combination of structural volume, cost and functional purpose of this invention.

[0023] This invention features a ball-holding container with four or more blocking protrusions arranged on its inner wall. The distance between these blocking protrusions and the bottom of the container is greater than the distance between these anti-blocking protrusions and the bottom of the container. This structure prevents the upper layer of tennis balls from moving with the turntable, ensuring that all the balls are smoothly fed into the lanes by the paddle, thus emptying the container. Without this structure, the balls in the container would move synchronously with the turntable, and only the balls with the rhythm adjustment paddle would enter the lanes; the rest would accumulate and move with the turntable, failing to enter the ball outlet and thus preventing the ball feeding function from being achieved.

[0024] This invention has a simple structure, small size, light weight, and is portable. It can be easily moved in the training field and is simple and quick to operate.

[0025] The invention features a modular design, allowing different functional modules to be connected through the ball outlet to achieve different training modes. Attached Figure Description

[0027] Figure 2 This is a schematic diagram of the ball-picking device of the present invention. Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0029] like Figure 1 , Figure 2 As shown, the simple tennis ball feeding device of the present invention includes a ball-holding container 1 and a support 7. The ball-holding container is placed on the support.

[0030] The ball container has a ball outlet 8 at the bottom. Preferably, it has two ball outlets.

[0031] An adjustable gate can also be installed below the ball outlet to facilitate switching between single-person and double-person training modes.

[0032] A ball outlet tube 5 is connected below the ball outlet. The ball outlet tube is a multi-section steerable tube, and its direction and position can be manually changed. The structure of the ball outlet tube can be a structure of existing technology.

[0033] A ball-dispensing device is connected to the bottom of the ball container. The ball-dispensing device includes a turntable 2 and a motor connected to it. The turntable is movably connected to the bottom of the ball container. A paddle 4 is provided on the outer edge of the turntable to dispense the tennis ball from the outlet. An anti-blocking protrusion 9 is provided on the inner wall of the ball container corresponding to the outlet.

[0034] The number of paddles can be set as needed, preferably 8-12 paddles evenly spaced. For example, 8 or 9 paddles are both acceptable.

[0035] Correspondingly, a ball release rhythm adjustment plate 3 is movably connected above the paddle on the outer edge of the turntable. The ball release rhythm adjustment plate is staggered from the paddle and the same number of them are used.

[0036] The ball release rhythm adjustment plate and the turntable can be connected by an existing movable connection method such as a hinge connection, which makes the structure simple and easy to use.

[0037] To better perform its anti-blocking and smooth flow functions, as a further improvement, five anti-blocking protrusions are arranged on the inner wall of the ball container corresponding to the ball outlet, with the middle anti-blocking protrusion being larger than the anti-blocking protrusions on both sides.

[0038] The inner wall of the ball container is equipped with four or more blocking protrusions 10. Six blocking protrusions may be used. The distance between the blocking protrusions and the bottom of the ball container is greater than the distance between the anti-blocking protrusions and the bottom of the ball container. This prevents the upper layer of tennis balls from moving with the turntable, ensuring all tennis balls are smoothly pushed into the lane by the pick, thus emptying the ball container.

[0039] The surface of the anti-blocking protrusion is preferably spherical. The surface of the blocking protrusion is preferably spherical.

[0040] To facilitate adjusting the ball height during training and for easy carrying, a height adjustment lever 6 is connected to the bottom of the ball container as a further improvement. The height adjustment lever is adjustable to the bracket via a gear and rack. This adjustable gear and rack connection is existing technology. This allows for manual adjustment of the height adjustment lever, thereby raising and lowering the ball container and ball outlet tube as a whole, making it convenient to use.

[0041] The bracket of this invention can also be folded up for easy carrying. Casters can also be installed at the bottom of the bracket for easy movement.
