Line system for sports and games, especially for training purposes

Description

The invention relates to a line system for sports and games, according to the preamble of claim 1, as used, for example, for marking playing or training fields.

It is common practice, for example, to have lines drawn on the floor of a sports hall to mark certain fields, e.g. for handball, basketball or indoor soccer. These fields are not variable and therefore always have to be used in the same dimensions and in the same place.

However, it is also known to use removable tape to mark out appropriate fields or line patterns on the hall floor for short-term training or game purposes, or to lay out appropriate cords such as skipping ropes for this purpose. The adhesive tapes can usually not be reused once they have been removed, while the cords that are laid out freely are relatively unstable in terms of shape and position, which means that a training grid that has been laid out can quickly become completely disorganized, for example, as the ropes cannot be fixed in position relative to one another. The spacing between several ropes laid out in a grid pattern on top of one another or relative to one another is also very arbitrary and the mutual spacing is uneven.

The object of the invention is to provide a line system of the above-mentioned type with which a line pattern required for training and/or playing can be produced simply, quickly and as often as required.

This object is achieved by a line system of the above-mentioned type with the characterizing features of claim 1.

Accordingly, several line elements of the same length are provided, which have fixing markings at the same longitudinal spacing. In addition, fixing elements are provided for quickly fixing at least two line elements in the predetermined position relative to each other. This means that any line pattern that can be constructed from relatively straight lines can now be quickly and easily provided and removed again.

It is advantageous if a dimensionally stable, longitudinally elastic plastic band that can be rolled up around a transverse axis is provided as the line element and the fixation markings, which are evenly spaced from one another, are also part of the fixation system and are arranged at a distance of approx. 10 cm from one another. It has proven particularly advantageous if the band is designed so that it essentially has a length of 155 cm, a width of 50 mm and a thickness of 1.5 mm and through holes of e.g. 7 mm diameter are provided as fixation markings. Thus, a band has a "working length" of 1.5 m between the outer holes and is provided with a fixing or coupling hole every 10 cm. It is immediately apparent that this line system offers almost unlimited variation possibilities for creating training or game line patterns. The bands, which are preferably made of non-slip plastic such as polyurethane and are preferably colored white, yellow or other colors commonly used to mark playing fields, can be put together or assembled as so-called line or coordination ladders. For this purpose, it is advantageous if, for example, a basic system consisting of nineteen bands each 1.5 m long is used, whereby a ladder length of 6 m with eleven evenly spaced cross "rungs" can be provided. The 10 cm rows of holes allow the cross rungs to be arranged at an even or variable distance from one another. A line system with a total length of 28.5 m can be put together from a basic system with nineteen band parts.
The line system according to the invention can be used optimally as/for:

- Coordination ladders, whereby, as mentioned above, the distances between the ladder rungs and the ladder rungs to the ladder stiles can be adjusted with transversely ending or transversely projecting rungs and also in stepped patterns;

- Coordination ladders in different variations, i.e. with rungs arranged at an acute angle to the longitudinal bars;

- adjustable for the speed system, adjustable for the stride length, through different rung spacing;

- for game exercises and shadow walking;

- as a coordination system with a ball;

- as a coordination system with ball and goal-shooting exercises;

- Dexterity training with beginners and those with learning disabilities, learning-walking-tactile system;

- for strength endurance training;

- Coordination system as a sun or umbrella, for exercises around a central point;

- Coordination system through triangles and squares;

- Start and stop lines, as auxiliary markings for group competitions, relay competitions;

- as a learning system: walk on the tapes with your eyes closed;

- in combination with other training elements such as rings, hurdles, balls or ropes;

- Line system for playing fields, quick construction of playing fields, ideal as a line system for so-called football tennis;

- as a replacement for player identification, worn as a belt or sash;

- Individual parts for catching games etc.;

- Vertical fields can be marked by hanging the bands on a wall or, for example, on a soccer goal, so that the goal opening can be divided into smaller individual fields, for example to make it easier to practice precisely shooting a ball into a goal corner.

It is advantageous if the system tape has a slightly curved profile in the transverse direction or if at least its longitudinal edges have a slight

-A-

Curve towards the laying side. This results in a smaller contact area when laying the tapes and thus easier movement of the tapes or the line system created from them. However, this is so elastic that it immediately gives way when the tape is stepped on and the entire tread width has a firm, non-slip contact with the ground, so that slipping accidents and at the same time the slipping of the line pattern is avoided.

According to the invention, various parts can be used or inserted as fixing elements, by means of which at least two of them can be fixed in a superimposed position relative to one another.

For example, a double-headed button can be used like a cufflink, although to make it easier to button the buttons, the band holes must also be provided with a slit like a buttonhole.

A snap fastener with very flat heads and variable locking height can be provided as a fixing element in a particularly advantageous manner. For better handling and in particular easier retrieval, a disk with an outer diameter of approx. band width can be provided on the head of the known snap fasteners, which are attached to the snap fastener or its head, for example by gluing or pulling it positively onto the snap fastener shaft. This disk can also have the same or a different signal color as the bands and can therefore be quickly seen and handled. If the disk also has a so-called butterfly shape, with a central indentation or cut, with the narrowest point being at most the size of the head diameter, it is also ensured that when the snap fastener is opened, the disk, which can be made of a relatively soft material and can come off the head if pulled tightly, is not pulled, but is grabbed crosswise in the zone of the corresponding cut directly on the snap fastener head and the push fastener head is pulled apart.

However, a narrow fastening tape that can be easily pulled through the holes in the tape can also be used as a fixing element. The fastening tape has a length of at least 1.5 x the tape width, can be laid around the coupled tapes when passed through and can be joined or tied together at the ends. A Velcro tape can be used as a fastening tape, with this tape being provided with Velcro elements at least at the ends that protrude beyond the tapes when the tapes are joined together. However, a so-called binding wire can also be used as a fastening tape, i.e. consisting of at least one wire embedded in plastic, such as is sold by the meter as garden supplies or as fastening clips of different lengths and thicknesses for freezer bags. It can be seen that these fastening tapes, in particular the wire tapes, can always be on hand at least as a "standby reserve" if there are not enough snap fasteners.

When several bands are coupled together or on top of each other, e.g. when creating a sun or umbrella system, the total thickness of the bands is relatively large, which then requires a special snap fastener of larger dimensions. In addition, this accumulation of band ends can become a stumbling block for athletes. It is therefore advantageous to provide a plate-shaped coupling part that has fixing holes on its peripheral zone, so that the several bands can each be individually connected in the desired, essentially radial arrangement using only this coupling part.

The coupling part can be disc-shaped, preferably round or polygonal, or preferably hexagonal to create line shields, whereby it is also advantageous if the diameter of the hole pitch circle is twice as large as the band hole spacing. If another hole is provided in the middle between the last two holes at the band ends, the radial extension can be compensated for by the coupling part without angular displacement.

Velcro fasteners can be attached to the top and bottom of the straps at equal distances as fixation markings, with the same Velcro fastener parts, i.e. Velcro parts or furry parts, being provided on one side of the strap. Round Velcro points with a width of almost the same width are probably the most advantageous for this.

However, cords with ring-shaped color markings on their surface can also be used as line elements. These line cords should have the same dimensional stability as the rubber cords used on strength training equipment or be made of the same or a similar material. These cord line elements can then also be used individually for other training purposes.

Binding parts or a substantially plate-shaped snap fastener can also be provided as a fixing part for the cord elements, with cross channels on the contact surfaces facing each other for coaxial or 90° fixing of the cords to each other.

However, slat-shaped bars can also be used as linear elements. These bars have recesses at regular intervals around their circumference for positively locking together, thus creating a plug-in system or modular system. The plug-in recesses can be dovetail grooves, while the bars each have dovetails on the front side.

However, the recesses can also be transverse grooves with half the batten thickness and a width equal to the batten width, so that two system bars can be stacked or inserted into each other at an angle of 90°.

The invention is explained in more detail below using several embodiments with reference to the drawing. They show:

In the basic embodiment shown in Fig. 1, line bands 1 are provided as basic system elements, which have through holes 2 along their entire longitudinal extent, at a uniform spacing of preferably 10 cm. Here it is shown how two line bands 1 arranged perpendicular to one another are connected to one another via a fixing button, of which only the head 3 is visible.

From Fig. 2 it can be seen how the linear bands 1, which are connected to one another via a double button 4, rest on a floor surface 5. It can be seen that the longitudinal edges of the bands have a curvature 6, whereby the contact with the floor in the unloaded state is reduced.

Fig. 3 shows a connection point between two line bands 1, with a snap fastener part 7 inserted into the coaxially aligned band holes 2. The snap fastener 7 here has two locking shafts 8 in a manner known per se, which can lock into one another at different heights with an identical snap fastener part in a position offset by 90°. A head disk 9 is attached to the underside of the snap fastener head 3, which serves to make it easier to identify and helps prevent the snap fastener parts from being lost too quickly.

From Fig. 4 the shape of the head disk 9 can be seen, which does not have a conventional round disk shape, but has central constrictions that run to slightly below the head 3, so that when the push button is opened on the rigid

The head 3 can be safely gripped and the soft head disk 9 does not have to be pulled.

Fig. 5 shows how a basic system kit consisting of nineteen line bands of 1.5 m each is used, whereby four bands are put together to form two longitudinal beams 11, on which eleven line bands are fastened as rungs 12, evenly spaced at 60 cm intervals. The sixth hole in the beams 11 is therefore used to fasten the rungs.

Fig. 6 shows a coordination ladder 13 which is essentially constructed in the same way as the coordination ladder 10 from Fig. 5, except that the rung spacing is uneven.

The coordination ladder 14 shown in Fig. 7 is essentially constructed identically to that shown in Fig. 5, except that the two longitudinal bars 11 are displaced longitudinally relative to one another, so that the rungs 12 attached to them at equal distances are no longer at right angles to the bars, but are inclined.

The additional coordination ladder 15 shown in Fig. 8 does not have two long stiles as in the previously described coordination ladders 10, 13 and 14, but rather four stiles that are put together as a folding ladder. It is clear that this folding ladder can be expanded as desired, including with additional ladder parts that can be arranged either parallel or perpendicular to the step coordination ladder shown here. Of course, all coordination ladder versions 10, 13, 14, 15 can be put together in any variant to form a complex pattern, right up to a circular pattern.

Fig. 9 shows how a playing field 16 can be assembled from the line bands, which can be used, for example, for the so-called football tennis.

is reversible. Two longitudinal lines 17 are coupled together from a corresponding number of line bands, between which three transverse lines 18 are attached.

Fig. 10 shows how several line bands are arranged in a radial manner to form a so-called coordination sun 19, whereby these bands 1 are held together in the middle by only one button 4.

Fig. 11 essentially shows the basic beam-shaped form of the sun 19 from Fig. 10, but here the outer ends of the six radially aligned bands are each connected by a band, so that a coordination screen 20 is created.

In order to avoid a band package that is too high when coupling several line bands together and that has to be held together by a single push button, a coupling part 21 is arranged in between, as can be seen in Fig. 12. The coupling part 21 shown in the figure is a round plate made of the same material as the line bands. It can also be made of a stiffer material. Near the edge of the coupling part, several holes 2 are arranged on a hole pitch circle 22, via which the line bands 1 can be fastened to the circumference of the coupling part 21.

Fig. 13 shows three further ways of fastening the bands together, namely with the help of a Velcro strip 24, which is threaded through the holes 2 and looped around the outside of the bands, after which the ends are chained together flat on top of each other. However, a Velcro strip 25 can also be used, the ends of which protrude freely outwards and are held together flat. Finally, it is shown how the connection is made with the help of a binding wire 26, with the ends twisted together to form a twist knot 27.

In the embodiment shown in Fig. 14, Velcro points 28 are arranged on the line band 1 as fixing elements, with the

-11 -

Velcro parts provided with hook parts and on the other side of the strap the softer, furry Velcro parts are arranged, as can be seen in Fig. 15.

In the embodiment shown in Fig. 16, cords 30 are used as line elements, which have evenly spaced marking rings 31 on their outer surface. The line cords 30 are held together by snap fastener plates 32, as can be seen in more detail in Fig. 17. The essentially identical snap fastener plates each have a snap fastener pin 33 and a snap fastener hole 34 in diagonal alignment, as well as intersecting channels 35 for guiding the cords 30 through.

Fig. 18, which shows a top view of the contact side of the push-button plates 32, clearly shows the crosswise arrangement of the two channels 35, as well as the arrangement of the push-button pin 33 and the push-button hole 34. Furthermore, it can be seen that cutouts 36 are provided on the corners of the plate without push-buttons, which serve to facilitate gripping when opening the push-button plate and which are particularly clearly visible in Fig. 21.

Fig. 19 shows how the cords are guided in the closed snap fastener plate 32 and it can be seen that they are slightly compressed at the crossing point.

Fig. 20 shows a diagonal sectional view of the push-button connecting parts, i.e. pin 33 and hole 34 in the engaged state, while Fig. 21 shows the second diagonal section, with the handle notches 36.

In the embodiments according to Fig. 23 to 25, slat-shaped line rods 40 are provided as line elements, which have a rectangular cross-section and have grooves 41 and 43 at regular intervals.

-12-

In the embodiment according to Fig. 23, dovetail grooves 41 are provided on the narrow side, which interact with dovetail pins 42 provided on the front side of the line rods 40.

In the embodiment shown in Fig. 24 and 25, transverse locking grooves 43 are provided on one broad side of the bars 40, the width of which is essentially equal to the width of the bars 40, while the depth of the groove is equal to half the thickness of the bars, so that the laid out line grid has a uniform upper line surface. The respective bar ends are designed as locking hooks which have a different orientation, i.e. are directed upwards at one end and downwards at the other end, so that two bars 40 which are to be coupled in a line one behind the other can only be simply hooked and pressed together to lock into place.
