The inventive holding element comprises several holders (610, 710, 810) combined into a bundle or a tuft, wherein said bundle or tuft is expandable oppositely to a tensile force substantially acting in a plane.

Description

Holding element for tea and system of a holding element and a Golfabschlagmatte

The invention relates to a holding element for teas set up for insertion in Golfabschlagmatten. The invention further relates to a system of such a holding element and a Golfabschlagmatte, preferably on artificial turf base.

Such holding elements ("tea holders") for holding teas (typically wood teas) for insertion into golf tee mats are known, which are typically made of rubber or soft, elastic plastic and have a base or foot and a cylindriion tapered towards the opposite The cylindrical section is typically slit three times longitudinally in an upper, sockel-remote area, divided into three clamping segments, with a coaxial one at the center of the three clamping segments Hole for receiving the tea or its shank, due to the dimensioning of the hole in the golf tee mat, the cylindrical portion of the tea holder, the hole in it and the tea stem the clamping segments under light pressure on the shaft of an inserted tea frictionally and hold this firmly.

The disadvantage of these tea holders is that they precisely define the position for receiving the tea axially. The golfer must therefore exactly aim and hit the hole in the tea holder when inserting the tea and has - unlike the tee on natural grass - no way to move the tea to another position, for example, to be able to change its position at tee. Also, the strength of the plug connection between tea and tea holder does not nearly match that of a tea inserted in natural turf.

Alternatively, slits are cut into the comparatively hard anchoring layer of synthetic turf in the golf tee ("turf back"), in which the teas can be plugged in. Although this solution is more cost effective than the former, it does not provide a sufficiently flexible and natural fixation of the tea achieved.

Other teeing devices for insertion in Golfabschlagmatten see no holding possibility for a wood tea, but have, for example, a rubber tee with a base and the opposite tapered, hose-like cylindrical portion which is inserted into a corresponding hole in the Golfabschlagmatte. In the inserted position, the cylindrical section on the recordable upper side projects out of the artificial turf of the golf club mat. On the opening of the outstanding tubular section of the golf ball is placed for tee. These solutions offer certainly no nature-like conditions that would come close to the tee on lawn.

Finally, there are still long-poled, very densely woven or tufted Kunstra¬ sen, in which the teas can be inserted directly at almost any point. However, the hold of the teas is not very good and certainly not comparable to that in the soil. The object is to provide a holding element for teas and a system of such a holding element and a Golfabschlagmatte that is easy to produce her¬ and allows close to nature fixation of Tees, so that Trai¬ ningsbedingungen are created, the conditions of the game Natural floors come closer.

The object is achieved by a holding element of the type mentioned ge with the features of the characterizing part of claim 1.

Two structurally different but functionally identical embodiments are summarized herein: On the one hand, "holding means combined into a bundle" are to be understood as meaning those which consist essentially of elongated bristles, fibers or the like and in an ordered arrangement This includes parallel, mutually inclined or crossed bristles or the like, which are bundled relative to a plane The tea is inserted with its shaft in play mode typically perpendicular to this substantially horizontal plane in the holding element, The holding means are displaced from the shaft in the corresponding area, so that the bundle expands at least locally against the clamping or restoring force of the holding means acting in this plane in this connection, that the force vectors entl ang the longitudinal axis of the inserted shaft from any radial direction - at least in the middle - normal (perpendicular) stand on this. The insertion means next to the holding means are so on the basis of the clamping force under pressure over a dependent of the insertion depth length of the shaft of the tea and hold it frictionally.

As an alternative to an ordered bundle, there may also be a tuft of disordered holding means (for example loops) which can be expanded in the same way in one plane against a normal force acting on this plane, ie acting on all of the radial directions on the shaft. It is not important, therefore, initially the arrangement of the individual holding means, but their elastic composite to a holding element. The cause of the elasticity of the holding element may be the material and shape properties of the holding means (intrinsic stability, compressibility, bending stiffness, elasticity, length, cross section, their anchoring, for example in a base fabric, the density of their arrangement and the like) themselves lie.

The multiplicity or density of holding means, on the one hand, causes the Einsteck¬ position for the tea in the extent of the extent of the entire holding element can be varied. Furthermore, regardless of the point of insertion, it ensures an overall relatively large contact surface with the shaft of the inserted tea due to a multiplicity of holding means close to the insertion point and thus sufficiently large friction as a function of the normal force and the insertion depth but independent of the insertion position. At the same time there is the advantage that due to the large number of holding means lying on the tee shaft, the tea will find different but strong support even with different insertion depths. This results in a better than the known tea age feel of the conditions in Natur¬ floors. A further advantage of the holding element according to the invention is that it is "self-healing", since the insertion point automatically closes again on account of the clamping force after the tea has been pulled out.

In a preferred embodiment, the holding element bristles as Hal¬ means. These bristles may be the bristles of a commercial industrial brush used. As a result, the production costs for the holding element can be kept low despite the advantages mentioned.

In another preferred embodiment, a pile fabric with pile fibers and / or pile loops is used as the holding element as the holding element. Such a pile fabric, ie tufted fabric, can have, for example, cut pile fibers (eg velvet, plush, velor) or uncut pile loops. This embodiment does not provide a custom-made as the known tea holder made of rubber and is therefore cheaper than this and at the same time offers the above advantages.

Also, a holding element may be used, which combines said bristles and such a pile fabric.

In a further advantageous embodiment, the holding element is a spacer fabric, knitted fabric or knit with elastic pile threads as holding means.

The holding means (bristles, fibers, threads, loops and the like) are preferably made of polyamide, polyester, polypropylene, polyethylene or natural hair.

In a particularly preferred embodiment, the holding element on a clamping element which compresses the bundle or tufts of the holding means at least partially and elastically. This has the advantage that no excessive demands are placed on the above-mentioned material and form properties of the holding means. The elasticity and stability of the individual holding means is in this case supported by the elasticity of the clamping element surrounding them. In this way, a sufficient or increased clamping or restoring force is generated. In this embodiment, the clamping force can be adjusted in a simple manner without changes to the holding means, or subsequently changed by more or less strong compression of the holding means.

The invention is further achieved by a system of the type mentioned above with the features of claim 9.

In a preferred embodiment, the hole in the golf tee mat is dimensioned in relation to the holding element such that the holding means of the inserted holding element are elastically compressed at least in sections from the golf tee mat to the bundle or tuft. In this embodiment, therefore, the golf tee takes over the function of the above-mentioned clamping element. This can save costs again, because the holding element does not need to be provided with the additional clamping element. By a suitable choice of the hole diameter as a function of the elasticity of the Golfabschlagmattenmaterials and the cross section of Halte¬ elements acting on the bundle or tuft clamping force can be adjusted and thus the friction-related holding force of the holding means can be adjusted to the shaft of an inserted tea.

However, the holding element can also be used with clamping element on the one hand to support the clamping force of the holding means on the other hand for easier insertion into the golf tee mat.

In a particularly preferred embodiment, the hole on the underside of the golf tee mat is gradually or continuously tapered towards its upper side. As a result, the cross-section of the retaining element inserted into the hole on the top of the golf tee mat is more narrowed and thus the holding means more compacted. This has the effect that the clamping force acting on a tea inserted into the holding element is the largest in the upper region of the golf tee mat. The gradient of the clamping force resulting at the corresponding narrowing point of the hole additionally counteracts the withdrawal of the tea from the holding element. This also makes it possible, if appropriate, to compensate at least partially for a restoring moment of the individual holding means which increases in the vicinity of the anchoring of the holding means.

"Summarizing" the holding means is to be understood here as a generic term which describes, on the one hand, the design of the bundle or tuft, which is inter alia due to the anchoring and the inherent shape of the holding means. On the other hand, the "active" compression, ie the compacting th of the holding means by the clamping element or the Golfabschlagmatte be¬ wrote. Furthermore, "expanding" or "expandable" on the one hand can describe the extent of local widening within the bundle or tuft in which its circumference does not change, but also the widening of the bundle or tuft altogether, in particular when using a tensioning device. elements or a bundle or tuft compacting golf tee mat. Other objects, features and advantages of the invention will now be described with reference to an embodiment with reference to the drawings. Show it:

The brush-shaped holding element according to FIG. 1 has substantially parallel aligned bristles 110. The bristles 110 are anchored on their underside in a bottom 112. This can either be done by making the bristles 110 in one piece from plastic on the base 112, for example by means of an extruder. the procedure are formed. The bottom 112 may alternatively be a Rückengewe¬ be, in which the poles of the bristles are anchored. To improve the lifespan, the poles can also be embedded in a stabilization layer arranged on the back tissue. It can be used for this purpose a variety of known brushes with the proviso that the elasticity and inherent stability properties of the bristles both allow the insertion of a tea as well as a sufficient frictional holding force on the shaft of the tea are able to exercise, see Fig. 2.

FIG. 2 shows a detailed detail of the brush-shaped holding element from FIG. 1, in the bristles 210 of which a tea is inserted. It can be seen that the bristles 210 are laterally displaced in the region of the penetrating shaft 222 of the tea 220. Due to their material and shape properties (Eigenstabili¬ ity, compressibility, flexural rigidity, elasticity, length, cross section, their Veran¬ tion, for example, in a base fabric, the density of their arrangement and the like.) And / or an externally by means of clamping element or golf tee off mat introduced clamping force the bristles located in the vicinity of the shaft are pressed against this. They thereby exert a clamping force on the shaft 222 indicated by the arrows 230, 232. Due to the coefficient of friction caused by the friction coefficient between the tee shaft material and the bristle material, this tensioning force causes a holding force with which the tea is held in the inserted position.

Towards the bottom 212, in which the bristles 210 are anchored, the strength of the bending and thus the restoring moment of the individual bristles adjacent to the tea 220 increases appreciably. As a result, in the case of a tea which is inserted very deeply into the holding means near the bottom 212, an upward force component is created, which determines the greatest depth of insertion of the teas.

In Fig. 3, another brush-shaped embodiment of the erfindungsge¬ MAESSEN holding element is shown, in which the bristles are not arranged parallel and perpendicular, but obliquely and cross. In Fig. 4, a holding element is shown, the holding means are formed from long loops 410, which are sewn, for example, in a base fabric 412, or otherwise anchored therein or on it (pile fabric with ungeschnit¬ tenen pile loops). Also, various means may be provided for improving the anchoring of the loops in the base fabric. As an alternative to the uncut pile loops shown, these can also be cut open so that a pile of velor is used. The pile receives at least a part of its internal stress and stability by the density of the fibers and / or by the mutual entanglement. The elasticity or inherent stability can additionally be increased by incorporating stiffer bristles or wire elements in addition to the fibers.

FIG. 5 shows the retaining element with loops as in FIG. 4, which is additionally provided with a tensioning element 514. The clamping element 514 circumferentially surrounds the clamp of loops 510 in sections and presses it together elastically. The clamping element 514 is preferably formed by a ring of elastically deformable material that supports the restoring force of the individual holding means, so that the tuft of loops when inserting a tea is additionally widened outwardly against the clamping force applied by the clamping element.

In FIG. 6, an embodiment of the holding element 600 according to the invention is combined with a golf tee mat 650 to form a system according to the invention. The Golfabschlagmatte 650 has on its upper side on artificial turf 652, which is anchored in a back web not shown in detail but known manner. Also in a known manner, the durability of the synthetic turf can be improved by an additional stabilizing layer. A composite artificial turf layer is applied on a damping layer 654. Various forms of damping layers are known. In the simplest case, the artificial turf layer 652 may be laminated on one or more foam layers. Better damping layers have further intermediate layers. For example, it is also possible to provide a three-dimensional textile spacer structure as a damping layer, which is made of an upper and a lower product layer of monophile or multiphilgam is formed, which are connected to one another by resilient pile threads and spaced voneinan¬.

In such a Golfabschlagmatte 650 a hole 656 is cut with freely selectable contour and generally also freely selectable dimensions. In this hole, the Hal¬ teelement 600 is introduced from below with a corresponding cross-sectional shape and size. In the exemplary embodiment shown, the base 612 of the retaining element is embedded in a corresponding recess 658 in the golf ablation mat 650. The length of the holding means 610 is adapted to the thickness of the golf tee 650 and in this case extends slightly beyond the anchoring of the artificial turf. In the present case, the holding means consist of a mixture of bristles and loops, which are anchored in the ground 612 in the manner described above. In addition to the intrinsic stability of the holding means 610, these are stabilized by the lateral lateral surface of the hole 656 in the golf tee mat 650. In the embodiment of Fig. 6, the walls of the hole 656 and thus because of a missing clamping element and the holding means are arranged substantially vertically.

For this purpose, in comparison, the hole 756 in the tee mat 750 according to FIG. 7 has a cross-section tapering from the underside of the golf tee mat to its upper side. As a result, and by the dimensioning of the hole in relation to the retaining element 700, the holding means 710, which consist in this case only of loops, at least partially compressed from the Golfabschlagmatte 750 to an upwardly tapering tuft.

In a similar manner, the embodiment of the system according to the invention according to FIG. 8 behaves in this case. In this case, the hole 856 in the golf club mat 850 tapers stepwise from the underside to the upper side thereof. As a result, the holding means 810 of the holding element 800 inserted from below into the hole, which in this embodiment consist only of bristles, in turn, compressed in sections from the golf tee mat into a bundle.

Since the golf tee mat is usually elastically deformable in (also) its horizontal extension plane at least in the region of the damping layer 654, it assumes the function of the tensioning element shown in FIG. 5 in the two exemplary embodiments of FIGS. 7 and 8.

The tapering of the hole causes the clamping force of the holding means in the upper region of the golf tee mat to be greatest and decreases toward the bottom 712, 812 of the holding element 700, 800. By means of this gradient, a small downwardly directed force component is added to the clamping force acting essentially perpendicularly on the lateral surface of a tea stem. This acts in the context of Fig. 2 explained, at a very deep inserted into the holding means tea upward force component, partially counter, whereby the holding force of the tea is increased in the holding element as a whole.

Such a funnel-shaped design of the hole also facilitates the insertion of the retaining element into the golf tee mat. Furthermore, insertion can be facilitated by inserting the bundle or tuft from retaining means into the golf tee mat together with a clamping element which surrounds it, at least in sections, as shown in FIG. 5.

In connection with FIGS. 6 to 8, the holding element and the abrading mat are shown as a plug-together system, so that a damaged holding element can advantageously be exchanged for a new holding element. Alternatively, however, the holding element can also be firmly connected to the tee mat by sewing, gluing or welding.

As a holding element, a spacer fabric with elastic pile threads can be used in addition to the already mentioned brushes and pile fabrics. The Pole threads then form the retaining means. Instead of the spacer fabric, it is also possible to use a spacer knit fabric with such elastic pile threads or a spacer knit with corresponding elastic pile threads.

The shape of the hole and the corresponding contour of the holding element is preferably round for reasons of production technology and ease of use. For the game operation, however, it may prove advantageous to make the holding element and in a corresponding way the hole oblong, such as oval or rectangular, diamond-shaped or similar.
