Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a training apparatus for racket sports. More particularly, the present invention relates to a training apparatus for developing proper tennis swing technique.

2. Description of the Related Art

In tennis, as with most sports, players develop advanced skills and technique through practice and repetition. Sometimes a player wants to practice a specific shot or stoke, or a partner is not always available. During these instances a tennis backboard or ball machine is commonly used, so that a player can practice individually. The present invention provides for a backboard training apparatus that enhances proper swing technique and can be used in small areas indoors or outdoors.

A number of devices have been developed to aid in tennis swing development. Among those are one such as described in U.S. Pat. No. 4,239,235, to Torres, which discloses the use of an inclined plane backboard to return a ball for skill development in ball games, such as football or tennis

U.S. Pat. No. 8,590,901, to Goldwitz, discloses a collapsible/folding throwback device that is used in skill development to return a thrown ball. Goldwitz also teaches the use of telescoping angle members to adjust the angle of the throwback device.

Additionally, U.S. Pat. No. 4,417,728, to Hay, describes a training apparatus for the improvement of strokes in racket games, which consists of a rebound surface with a curved upper portion that stops a ball delivered by a racket and returns it to the racket holder.

The aforementioned devices attempt to aid in skills development of ball games or racket sports using a rebound surface with an angled or curved backboard. However, these training devices are generally very large and difficult for less skilled tennis players since the ball is returned at difficult angles and varying velocities.

It is therefore an object of the present invention to provide a tennis backboard without the drawbacks of size and unrealistic ball trajectory return. It is further an object of the present invention to provide a tennis backboard that can be used by players of all ages and heights through the use of telescoping and adjustable frame members.

BRIEF SUMMARY OF THE INVENTION

The present invention provides a training apparatus for developing proper tennis swing development. An exemplary feature of the invention is a curved return guide ramp which provides proper delivery of a tennis ball to the correct height of the user, to enable the user to learn proper swing development. The present invention uses telescoping vertical support members to adjust the height of the apparatus to an appropriate height for the user, which in combination with the return guide ramp, returns a tennis ball at the correct height for the user, and thus provides a clear advantage over prior methods of the aforementioned training apparatuses.

It is contemplated that the training apparatus will be made up of a lightweight parallel frame having a curved return guide ramp at a proximal end and a straight backstop panel at a distal end. Parallel frame members are attached to vertical support members, which are telescoping for being adjusted to the height of various users. Additionally, the vertical support members of the parallel frame members are collapsible for easy storage and transportation of the training apparatus. A flexible material is disposed across the width of the parallel frame members, and extends to the backstop panel and return guide ramp, providing a ball support and return surface.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings, and more particularly to FIG. 1 there is shown a training apparatus to aid in proper tennis swing development, which is described as an exemplary embodiment of the present invention. The training apparatus includes a frame means having two parallel frame members 10 and 20, with vertical support members 50, 60, 70, and 80 attached thereto, a backstop panel 30, a return guide ramp 40, and a rebound surface 90.

As shown in FIG. 1 vertical support members 50 and 80 are located at the proximal end of the parallel frame members 10 and 20, while vertical support members 60 and 70 are located at the distal end of the parallel frame members 10 and 20. Vertical support members 50 and 80 are preferably sufficiently shorter than vertical support members 60 and 70, for causing the rebound surface 90 of the training apparatus to be situated at approximately a forty-five degree angle relative to the ground on which the training apparatus is located. As shown in FIG. 3, vertical support members 60 and 70, are attached to frame members 20 and 10, respectively, at angle adjustment joints 61 and 71, respectively. As further illustrated by FIG. 3, vertical support members 60 and 70 contain telescoping extensions 62 and 72, respectively. Angle adjustment joints allow the training apparatus to fold flat for storage and transportation, while telescoping extensions allow the training apparatus to be adjusted for the height of different users. FIG. 2 shows vertical support member 50, as well angle adjustment joint 51, and vertical support telescoping extension 52. FIG. 5 shows vertical support member 80, angle adjustment joint 81, and vertical support telescoping extension 82. The telescoping extensions 52 and 82 and angle adjustment joints 51 and 81 of vertical support members 50 and 80, respectively, function the same as those of vertical support members 60 and 70.

Referring to FIG. 5, which shows a perspective view of the backstop panel 30. The backstop panel 30 connects the parallel frame members 10 and 20 at distal end, and is arranged upwardly oriented at a predetermined angle.

Additionally, the backstop panel 30 has folding joints 31 and 32 that allow the training apparatus to easily fold flat for storage and transportation.

As shown in FIG. 2, a side view of the return guide 40, the return guide 40 connects the parallel frame members 10 and 20 at proximal end, and is curved in shape to cause a ball to be returned to the user. The angle adjustment joints 41 and 42 allows the return guide ramp 40 to be adjusted to different angles, so that a tennis ball will be returned at the correct height for various users. Further, the angle adjustment joint 41 aids in folding the training apparatus flat for storage and transportation.

Referring to FIG. 1, a perspective view of the training apparatus, the rebound surface 90 consists of a flexible material disposed across the width of the parallel frame members 10 and 20, and extending to the backstop panel 30 and return guide ramp 40, and connected thereto for providing a ball support and return surface. In the preferred embodiment of the invention, the rebound surface 90 is comprised of mesh netting, and includes indicia 91 representing the service lines of a tennis court. However, the rebound surface 90 could be constructed of any material of sufficient rigidity that would allow a tennis ball to be returned at a trajectory and time approximate of the normal return of an opposing player. Additionally, the indicia 91 on the rebound surface 90 could be comprised of hitting targets, graphics, logos, or the like.

Referring now to FIG. 6, a perspective view showing the collapsible nature of the training apparatus according to the invention, the training apparatus can be folded flat for easy transportation and storage. The backstop panel 30 folds towards the frame members 10 and 20 at folding joints 31 and 32. The return guide ramp 40 folds toward the frame members 10 and 20 at angle adjustment joints 41 and 42. The vertical support members 50, 60, 70, and 80 telescope to the shortest position at telescoping extensions 52, 62, 72, and 82 respectively. Also, the vertical support members 50, 60, 70, and 80 fold towards frame members 10 and 20 at angle adjustment joints 51, 61, 71, and 81 respectively. Finally, as shown in FIGS. 4 and 6, the entire training apparatus then folds in towards itself at frame member folding joints 11 and 21.
