never innovation concerns a training device for table tennis.

The innovation is based on the task, while avoiding one Great technical effort to develop an inexpensive training device that is suitable for both beginners and advanced users suitable is.

According to the innovation, this object is achieved by a table spanned by a net in its longitudinal center, which has a * for Table tennis table ^ the prescribed height and length, but a smaller width, and the two longitudinal halves of which are each composed of several plate parts, which in a basic position all together have a square table surface form, and some of which plate parts are displaceable from the basic position into a second position, in which at least one area approximates that for a table tennis table prescribed width.

A table tennis table in accordance with regulations has a table top length of 274 cm, a table top width of 152 cm and a table top height of 76 cm. The new training device offers in its

Basic position thus the possibility of certain strokes on one Table with significantly reduced width, but below the original train under the same conditions. Furthermore, the new device offers the possibility of shifting individual plate parts in a second position in a certain area of the table to produce a plate width corresponding to a table tennis table in accordance with regulations. At the same time, however, due to the displacement of the mentioned plate parts in the table, corresponding openings are created, so that missing the plate parts against which a ball is played can easily be registered. After all, there is new training device the possibility of providing a different arrangement of the plate parts and thus different degrees of difficulty for the two longitudinal halves of the table, so that players with different performance levels can train together in a meaningful way.

In an expedient Auführungeform, each longitudinal half of the Tables consist of three strip-shaped plate parts of the same length, which in the basic position are side by side in the longitudinal direction lie, and of which the respective outer plate parts can be moved into a second position. It is useful to when the respective outer plate parts with their ends pointing towards the front side of the table each move a pivoting curve in the vicinity of their other end out of the basic position can be pivoted into a second position in which all plate parts together form a star shape.

In this special solution, they are in the second position There are basically three playable record areas available for each player. Due to the star-shaped arrangement of the outer Plate parts can be used in particular diagonally flhci the table

excellent practice of guided strokes. Since the entire middle area is only formed by the middle, immovably arranged strip of the plate, the result is relatively large, triangular areas not covered by plate parts, which force the player to hit the three narrow plate areas very precisely align.

The pivoting of the outer. Laying plate parts is expediently not carried out around a fixed point of rotation, but preferably around a pivoting curve, so that the ends of all three plate parts lie at least approximately on a straight line in the frontal area of the table. In this case, the ends of the outer plate parts pointing towards the center of the table expediently have an inner bevel which, in the pivoted position, forms a contact surface on the middle plate part.

The displacement of the outer parts of the flats from their basic position out could basically be done by hand. Preferably, however, one is assigned to the outer plate parts Pivoting linkage is provided with a lock that holds these plate parts in their pivoted position. Such a thing Linkage can be equipped with a manually operated gear, so that e.g. by adjusting a crank or the like, at least the two outer plate parts of a longitudinal half are pivoted into their star-shaped position. Such a thing The gearbox and the swivel linkage mentioned can, in principle, be the drive means that are customary for opening or tilting windows, for example correspond.

Each plate part can have at least one support leg. To make things easier these support legs are useful during transport

swivel away under the plate part, with the one on the middle
Flattenteil attached support leg can be designed so that it automatically locks the two outer plate parts in their basic position in its pivoted rest position.

In the longitudinal center of the table, a support device is preferably provided to which the network is attached, which for a
Table tennis game has the prescribed dimensions. The new training device can, however, be expanded in its area of application particularly expediently if a second net is arranged in a height-adjustable manner above the net, the lower edge of which defines a penetration area with the upper edge of the first net. This also makes it possible to control the altitude of the struck ball and train with it. As a result of the height adjustability, the clear height of this penetration area can be easily adapted to the respective skill of the player.

The drawing is an exemplary embodiment
of the innovation shown schematically. Show it?

FIG. 1 shows a training device for table tennis in a plan view and FIG. 2 shows the illustration according to FIG. 1 in an end view.

The training device shown consists of a table 1, the longitudinal halves of which consist of three strip-shaped plate parts 2, 3 of the same length, which are shown in dashed lines in FIG
Basic position I each lie next to one another in the longitudinal direction and all together form a rectangular table surface. Length and height

this rectangular table surface corresponds to those of a regular table Table tennis.

FIG. 1 also shows that the respective outer plate parts 3 with their ends pointing towards the end face of the table 1 each by a pivot curve located in the vicinity of its other end are pivotable from the basic position I out into a second position II, in which all plate parts 2,3 together one Form star shape. The position II is shown in Figure 1 in solid lines. According to FIG. 1, they are pointing towards the center of the table Poor the ends of the outer plate parts 3 with an inner bevel 4, which is in the pivoted position II forms a contact surface on the middle plate part 2.

Figure 2 shows that each plate part 2, 3 with a support leg 5 is provided. In the longitudinal center of the table 1, a support device 6 is provided, which also has at least two Support legs 7 may have. Two nets 8, 9 are attached to the support device 6. The lower net 8 is used for table tennis games valid dimensions and can be commercially available. The upper net 9 is arranged so as to be adjustable in height and also defines it its lower edge together with the upper edge of the lower net 8 a penetration area 10. By clamping screws 11 is the device for adjusting the height of the network 9 indicated. A lower position of the upper network 9 is shown in dashed lines.

The pivot rod mentioned in the introduction to the description as well as in the claims for protection, the gear for this, clamping devices for the nets and the rollers for the support legs are not shown in the drawing, as this is general known, commercially available elements.
