Description

Ping pong ball wall (10) consisting of a carrier (1) , a shock-absorbing material for a flying table tennis ball (2) and a low-friction cover for a rotating table tennis ball (3) .

State of the art

Existing training devices for table tennis are, on the one hand, robotic ball machines.

On the other hand, so-called return boards are available in stores. These are usually aluminum constructions with glued coverings on surfaces with adjustable angles. These constructions are mounted or set up on the opposite side of the table tennis table and in principle simulate a huge table tennis bat that blocks the ball back.

Both variants - ball machines and kickback walls - usually have the disadvantage of high acquisition costs, not least due to the large amount of space required, which inevitably comes with costs: an entire table tennis table is usually required for these training devices, which in turn requires a suitable space to set up and / or a suitable storage room when not in use. As a result, these devices are only available to a limited audience.

A simple variant of training that is well known is to leave one half of a table tennis table folded up and play against this ball wall. However, it is also generally known that you cannot train ambitiously in this way that is too simple.

This problem - a simple table tennis training device, which the practitioner (12) An ambitious training enables it to be made available to the broadest possible audience through low acquisition costs and small space requirements, is achieved with the invention, the main features of which are listed in protection claim 1.

The solution: Simple yet not so simple

The invention (10) is a table tennis ball wall, consisting of a support (1) , one for a flying shock absorbing material (2) and a low-friction cover for a rotating table tennis ball (3) ; being the invention (10) can be permanently mounted, hung up or, best of all, simply set up and put away again at the exercise site.

Normal tables and other suitable solid surfaces can be used as exercise tables. Simple worktops or the well-known, very inexpensive, lacquered plywood panels have been tried and tested and are available everywhere for little money. The inventor himself tested his invention for a long time on a normal work table and later on two old school desks from the bulky waste. No problem.

• 1 shows in side section the basic elements of the invention: a carrier (1) e.g. made of wood, a shock-absorbing material (2) , e.g. clamping felt, foam, fleece, wool, cork or similar which on the carrier (1) is mounted and finally with a low-friction cover for a rotating table tennis ball (3) , for example polyester or silk is covered.
• 2 shows an advantageous embodiment of a front view of the invention in an exploded view. The carrier (1) consists on the one hand of a carrier plate (1a) , e.g. poplar wood 6-10mm and a support frame attached to it (1b) , e.g. wooden strips 20 × 20, suitable around the material (2) , for example, clamping felt ISOVER 20mm or foam 10-20mm to be securely enclosed and to be useful for attaching the cover (3) eg with masking tape and staples. The whole thing is concealed and protected with a frame (4) e.g. made of aluminum U-profile 20x30x20. One easy move (6) as well as swiveling feet (5) which do not interfere with transport and storage and ensure stability when setting up, make the invention complete and comfortable. Assembly means (7) can be screws, tape, staples, etc.
• 3 shows this advantageous embodiment in side section and in an exploded view.
• 4th shows a particularly interesting variant of an advantageous embodiment in side section and in an exploded view, with the back of the carrier plate (1a) another material ( 2 B) different in properties to the material (2a ) is mounted on the front. The materials are coated (2a and 2 B) each with references (3a and 3b) which can be differentiated by color, for example. The different materials (2a respectively. 2 B) ensure different throwing speeds, throwing distances and throwing angles of the table tennis ball and thus enable a variable training experience on two different sides.
• 5 . shows the in 4th described variant of an advantageous embodiment in side section after assembly.
• 6th shows a section in high magnification 5 , where you can see very precisely, such as on the front of the carrier plate (1a) a shock absorbing material (2a ) from the carrier frame (1b) is bordered, on which also the low-friction cover (3a ) with e.g. adhesive tape (7) is attached; where you can see how on the back of the carrier plate (1a) another shock absorbing material ( 2 B) is mounted and with a different (e.g. different colored) cover ( 3b) is coated, which on the carrier plate (1a) with tape, for example (7) is attached and then stapled; where you can see the frame (4) - here a U-profile - protects the entire upper edge and optically conceals the fastening process.

Note: The other shock absorbing material ( 2 B) For optical and manufacturing reasons, it is left in the depth over the frame (4) of the U-profile - the invention looks nice and slim, you save a second support frame (1b) , in addition, the U-profile is both single-sided with materials (2) as well as with double-sided execution (2a and 2 B) usable.

How do you train ambitiously on this invention?

The combination of material (2) and reference (3) Basically allows a training with hard topspin strokes without the ball being thrown over the end of the table and the flow of the game being broken. If necessary, you can give the table tennis ball wall a small angle of inclination by attaching, for example, adhesive felt under one side of the swivel feet or you simply put a few playing cards / cardboard or similar on one side under one side of the feet until the ball throw-back angle is optimally at the desired impact strength and the applied spin is set.

It should be noted that the reference (3) how a so-called anti-top coating works, that is, the ball maintains its direction of rotation and is only slowed down minimally in its speed of rotation. A topspin comes back like an undercut ball played by a training partner.

An undercut ball (push) played by the practitioner comes back as a pleasant short topspin and is usually made to jump twice. This gives the practitioner enough time to prepare for the following counter / topspin: footwork, body rotation, gaze, breath, technique.

You train - just like on a tennis ball wall - on about half the length of a table tennis table. Shorter table lengths have also been tried and tested and are quite possible, e.g. in the office or in the workshop.

A basic exercise series might look like in 7th and 8th somewhat childish but clearly presented. In 7a begins the practitioner (12) - shown in simplified form by a table tennis bat with a directional vector of the hit just made - with an undercut serve, which is thrown back as a gentle topspin and, for the sake of simplicity, is made to jump twice.

In 7b If the practitioner pulls on the ball that has just been thrown back with topspin, the ball - only slightly deflected upwards on the ball wall - is thrown back as a long undercut ball.

In 7c the practitioner pushes this undercut ball back with an undercut. This is considered to be the easiest response to an undercut ball. The ball is then deflected slightly downwards on the ball wall and returns as a gentle, short topspin, which is made to bounce twice for the sake of simplicity and tranquility of the exercise.

In 7d the practitioner pulls back lightly or sharply with topspin (see 7b) - the exercise cycle has closed and can be repeated and intensified as long as desired.

The practitioner gains from the great preservation of the self-induced spin - precisely because of the use of a low-friction cover (3) - Very good feedback on both his induced spin using technology and the effect of various rubbers and rackets. Table tennis players in western countries like to test equipment and a test at home saves training hours in a club. Advanced series of exercises can consist in 7c instead of reacting with a simple push, instead pulling it up again with a topspin. This is considered a demanding shot. The ball is drawn even further in its rotation and would come back as an even stronger undercut ball. Which one in turn could try to attract with topspin, etc.

Over time, the practitioner gets a good feeling about which balls he can still pull and which ones are better pushed. This is the basics of any topspin / offensively oriented service acceptance.

With the invention, the demanding topspin above the table (flick) can also be achieved by using a strong cushioning material (2) be practiced, which allows the ball to drain for a relatively short time and thus shifts the game over the plate. Side spin variations can be practiced (so-called Banana Flick, Strawberry Flick), the quick changes from forehand to backhand can be practiced, etc.

But push training can also be expanded: a continuous push would pull the ball further and further in a direction of rotation. The famous push-block technique can be practiced at home. For this purpose, however, a less shock-absorbing material can be used (2) and you can tell now that it makes sense to both sides of the wearer (1) with different materials (2a and 2 B) to prove.

Final note: use played balls. New ones are too “floury” and easily get caught in the cover.
