Abstract

The bar for a jump, for equestrian show jumping training, is a rod body (1) with an outer mantle (2) of a shock-absorbent material and an inner core (3), with end caps (4). The outer mantle is a sleeve with a wall thickness of at least 20% of the rod body diameter. The core is composed of alternating units (5,6) where one has bending flexibility and the other is relatively stiff against bending, to give the core a maximum bend of 20 mm under its own weight and at least 200 mm at the center when under a loading pressure, without a plastic distortion.

Description

The present invention relates to an obstacle rod for building obstacles for show jumping, comprising an elongate rod body, an outer sheath made of a shock absorbing material, and an inner core. Furthermore, the invention comprises a riding obstacle.

Obstacle bars are especially designed in lengths of between three and four meters. They are used in particular for the construction of obstacles, such as high-jump obstacles, high-long-jump obstacles, such as oxern or triple bars. Such obstacles have in addition to the obstacle rod the obstacle stand with rod mounts and grille and other obstacle structures. For the most part, the known obstacle rods are made of wood and have a diameter of 10 cm to 12 cm. However, such wooden poles have a relatively high weight and are relatively inelastic, so that in a fall of horse and / or rider considerable danger potential emanates from these wooden poles. In addition, there is a considerable danger of splintering, which often causes dangerous and painful injuries in animals and humans.

From DE-A1 222 06 81 an obstacle rod of the type mentioned is known, in which the rod body consists of an inner core, which is formed by a wooden rod, said inner core is enclosed by an outer shell, for example, of a plastic film or a foam sheet can exist. This outer jacket essentially serves to form a closed shell to prevent the inner wooden bar from drying out. In addition, a certain contact protection is achieved by the use of a foam film. However, this known obstacle rod still has the disadvantages of high weight and low elasticity, so that a high risk of accidents associated with this rod. If in this known obstacle rod, the outer jacket is made of shock-absorbing material, han It is only a very thin coating, so that the risk of injury is not significantly reduced.

From DE 298 18 595 U1 a safety obstacle rod for equestrian sports is known, which is composed of several sections which are interconnected by magnets. This safety obstacle bar can be made of wood or plastic. Although the stability is reduced by the multi-part of the obstacle rod, so that the rod resistance and thus possibly the risk of accidents is reduced, but the individual parts are still very difficult due to the high weight and can fall apart uncontrollably due to the multi-part in a fall, so that even increases the risk of accidents. In addition, this obstacle rod, if made of plastic, has a relatively large deflection, which is why it is not suitable for the accurate construction of an obstacle. Since the rod bodies used are made of wood or plastic, they are hard, which is also a significant risk of injury.

Also from GB 222 956 A an obstacle rod is known, which is constructed in several parts and consists of several juxtaposed and connectable rod sections. This results in a good transportability. However, stiffeners are provided in this obstacle rod in the individual rod bodies in order to ensure adequate flexural rigidity of the existing plastic rod. This results in high production costs. In addition, these plastic bodies are hard, so that there is still a high risk of accidents. Due to the stiffener with inner stiffening profiles also results in a low bending elasticity, which is also disadvantageous in a fall, as is the case with the known wooden rods.

Also from DE-U-297 17 699 is an obstacle rod, which is constructed in several parts known.

The present invention is based on the object to create for show jumping an obstacle rod and an obstacle of the type mentioned above, which are characterized by a reduced risk of accidents at high functional performance. In particular, it should - starting from the prior art, as described for example in the aforementioned DE 222 06 81 A1 - an obstacle rod are created, on the one hand has a relatively low weight and on the other hand offers a high level of accident protection, so they especially suitable for use with young horses or riding beginners to the accident to reduce danger for riders and animals and thus to improve the training possibilities.

According to the invention this is achieved in that the inner core comprises first and second elements, wherein the elements, at least a first element at least two second elements, at least partially changing sequence in the longitudinal direction of the obstacle rod are interconnected, and wherein the first elements resiliently bendable elements and the second elements are flexural elements compared to the first elements.

On the one hand, such an obstacle rod according to the invention is sufficiently rigid, but on the other hand also so flexible that an accident risk is reduced to a significant degree. The advantages of this obstacle bar, however, are primarily to seek in the improvement in the training of rider and horse (non-violent training). Due to the flexible rod, the core of which is shock-absorbing, and in particular softly enveloped by the sleeve, the risk of accidents is considerably reduced. In addition, the idea associated with the use of the obstacle rod according to the invention leads to a psychological effect of anxiety reduction in rider and horse, only to drive against a flexible, yielding and harmless obstacle, and increases the motivation to jump. Without fear, the head remains free for the essential things in show jumping, so that an increased ability to learn occurs.

The overall resilient core of the obstacle rod according to the invention may in a preferred embodiment - depending on the total length of the obstacle rod - certain number of first, resiliently flexible spring elements - optionally also only such an element - which with the second, rigid elements to a unit that the Total length of the obstacle bar corresponds to be connected. This modular construction has the advantage that different rod lengths can be realized by simply adding or removing individual elements. As further advantages of this modular design, the simple and cost-effective repair and the simplified transport option can be mentioned.

In this case, in particular, the material, the shape and the arrangement of the flexurally elastic elements and the flexurally rigid elements can be selected and dimensioned in this way that the bar body has a maximum deflection of about 30 mm, preferably 20 mm, when loaded by its own weight, wherein the bending elasticity of the bar body is such that a deflection under load of at least 200 mm without plastic deformation of the elements is possible ,

The outer jacket may preferably consist of a sleeve with a wall thickness of at least 20% of the diameter of the obstacle rod. Thus, the inner core of the rod body is comparatively thin, whereby a significant weight reduction is made possible; because the outer sleeve of shock-absorbing material has a large wall thickness, so that a considerable cushioning effect is given. In addition, the obstacle bar according to the invention has a large bending elasticity, so that in an impact on the obstacle bar not only in the region of the shock absorbing material, an energy absorption, but by the deformation of the obstacle bar in the elastic region additional energy is consumed, so that the overall impact energy significantly reduced can be. Due to the low weight and the obstacle resistance is reduced overall, which also contributes to a significant reduction in the risk of accidents.

Overall, due to the above advantages, the obstacle bar according to the invention is particularly useful when training the training of young horses or training children and inexperienced riders, because - as already indicated - and the psychological effect is generated in the riders that reduces the fear of jumping because the rider knows that in case of an accident the risk of injury is minimized. However, with regard to the requirements placed on the obstacles, the obstacle rod according to the invention is sufficiently rigid, so that a straight course is present in the obstacle.

Advantageously, the flexurally elastic element consists of a plastic or a plastic composite material, in particular polyamide or glass fiber reinforced polyamide, and is formed as a solid material with a circular cross-section. The rigid elements are expediently made of tubular steel, wherein the length of the flexurally elastic element is in each case 3% to 10%, preferably 5%, of the total bar length. The wall thickness of the tubular material of the flexurally rigid elements is preferably 1 mm to 4 mm, in particular 2 mm. The flexurally elastic elements and rigid elements have according to the invention the same outer dimensions and preferably have an outer diameter of 30 mm to 35 mm, in particular of about 33 mm.

In the various figures of the drawing, the same parts are always provided with the same reference numerals, so that they are usually described only once in each case.

As initially shown in the drawing in Fig. 1, in which an obstacle rod according to the invention is shown, this comprises an elongated rod body 1, which consists of an outer sleeve 2 formed as a sleeve and an inner core 3. The total length LG of the rod can, as is usual in show jumping, be approximately in the range of 1.5 m to 4.5 m, preferably 3.0 m.

The outer sleeve 2 consists of a flexible, shock-elastic material, which may be in the illustrated embodiment, in particular a polyurethane foam having a density of at least 40 kg / m ³ and a compression hardness of at least 60 kPa. The sleeve 2, which may preferably have an outer diameter D2A of 100 mm and an inner diameter D2I of 34 mm, is slid over the entire core 3 and fixed to the ends of the rod body 1 with preferably made of polyamide plastic covering caps 4, one of which as an item in Fig. 7 is shown. The outer sleeve 2 preferably has an annular cross section in the basic shape. Their wall thickness S2 is at least 20% to 35%, in particular 25% to 30%, of the outside diameter D2A of the sleeve 2 or of the rod body 1.

The inner core 3 of the rod body 1 of the obstacle rod according to the invention consists of a resiliently flexible first element 5 and rigid second elements 6, which are arranged in an alternating sequence. At the ends of the rod body 1 each rigid elements 6 are arranged, which are connected to each other via the flexurally elastic element 5. By this arrangement of the rigid elements 6, a high stability of the rod body 1 is ensured.

The obstacle rod according to the invention is used to build up obstacles according to the invention for show jumping, such as steep jump obstacles, whereby a combination with obstacle elements can take place, as shown in FIGS. 8 to 10. The obstacle rod according to the invention can also be used in high-long-jump obstacles, as oxern or triple bar, are used, provided that - as exemplified by Fig. 11 - have a suitably designed rod support member 25 for the obstacle rod. By using an obstacle rod according to the invention in such an obstacle, the risk of accidents when jumping is minimized, which - as already stated - is of importance for the jumping performance and therefore for the preferred use of a rod according to the invention for training purposes.

The two rigid elements 6 - see Fig. 2 - have in the illustrated embodiment, the same length L6. In the case of a preferred total length LG of the bar body 1 of three meters, the length L6 of a rigid element 6 may be in particular 1330 mm. The rigid elements 6 are tubular, in particular made of steel, wherein preferably a weldable steel, in particular a steel St 35, can be used. The wall thickness S6 of the tubular material is 1 mm to 4 mm, preferably 2 mm. Its outer diameter D6A is in particular 34 mm and the inner diameter D6I 30 mm.

In Fig. 3, a flexurally elastic element 5 is shown, which preferably has a length L5 of 150 mm when using the rigid elements 6 according to FIG. The outer diameter D5A of this rod-shaped bending-resistant element 5, which consists of a solid material, is 34 mm, so that the flexurally rigid elements 6 and the flexurally elastic element 5 have the same outer diameter. This is in view of the axially successive and coaxial arrangement (common longitudinal axis X-X) of the rigid elements 6 and the resiliently flexible elements 5 and their common wrapping by the outer sleeve 2 from the viewpoint of high stability and in particular bending stiffness of the obstacle bar according to the invention is advantageous.

The flexurally elastic element 5 is made of plastic or a plastic composite material, preferably of polyamide or of glass-reinforced polyamide. In the illustrated embodiment, a polyamide material PA6 is used with the mechanical properties listed in Table 1 below.

In order to connect the flexurally rigid elements 6 with the elastically bending element 5 arranged centrally therebetween, an adapter part 8 is preferably welded to the tubular flexurally rigid elements 6 at one end, as shown in FIG. 6 (weld SN1).

For this purpose, the adapter part 8 - see FIG. 4 - a cylindrical projection 9, which merges into an annular collar 10 with a cone 11. At the annular collar 10, a threaded pin 12 is integrally formed on the front side. The adapter part 8 has an overall length L8 of preferably 45 mm, wherein the threaded pin 12 has a length L12 of 25 mm and the cylinder shoulder 9 has a length L9 of 15 mm. The outer diameter D10A of the annular collar 10 is 34 mm According to the external thread diameter of the threaded pin 12 is - as can be seen from Fig. 3 - in the end-side end faces of the flexible element 5, a threaded bore 14 with a thread depth T14G of preferably 30 mm. Thus, by screwing the threaded pin 12 into the threaded bore 14 of the flexurally elastic element 5, a connection between this and the two adjacent bending-resistant elements 6 take place.

The external thread formed on the adapter part 8 has in a preferred embodiment a thread size M 18 x 1.5, i. it is formed a fine thread, whereby a positive and non-positive connection between the rigid elements 6 and the flexurally elastic element 5 is achieved, which prevents that in the transition region of the elements 5, 6 a game is present.

At their outer ends, the rigid elements 6 may preferably have threaded inserts 15, as shown in Fig. 5. These threaded inserts 15 have an annular collar 16 on which a cylinder neck 17 is integrally formed, with a conical transition 18 between the two parts is present. The outer diameter D15A of the threaded insert 15 corresponds to the inner diameter D6I of the tubular, rigid element 6 and is preferably 30 mm. The length L17 of the cylindrical projection 17 is preferably 15 mm and the total length L15 of the threaded insert 15 is 20 mm. The outer diameter D16A of the annular collar 16 is 34 mm and thus corresponds to the outer diameter D6A of the flexurally rigid element 6.

The threaded insert 15 is inserted with the cylindrical projection 17 in the respective end of the rigid element 6 and then welded in the region of the conical transition 18 between the annular collar 16 and cylinder extension 17 with the rigid element 6 (weld SN2 in Fig. 6). Center through the threaded insert 15 extends a threaded hole 19 with an internal thread of the thread size M8. In each case on the threaded insert 15 having the end of the rigid elements 6, a cap 4, as shown in Fig. 7, pushed and schraubgemäß connected.

The cover caps 4 each have the basic shape of a cylindrical disk and a centrally arranged in a top surface F4A of the cylinder, in a form-fitting manner the contour of the end faces of the rod body 1 adapted recess A4, so that they can be plugged onto the rod body 1. From the other top surface F4B ago penetrates an axial, in particular lowered bore B4, the cap 4, whereby by means of a screw, not shown, a screw with a terminally arranged on the rod body 1, rigid element 6 is possible. The outer diameter D4A of Abdeckkapppe 4 is preferably about the same size as the marked in Fig. 1 outer diameter D2A of the outer sleeve 2, so that the two parts 2, 4 can connect flush to each other.

The flexurally rigid elements 6 and the flexurally elastic element 5 of the obstacle rod according to the invention are designed and arranged with respect to the material used, their shape and their arrangement such that the rod body 1 has a virtually imperceptible deflection in a two-sided, end-side support, so that it runs optically straight. In this case, according to the invention, a maximum deflection of 30 mm may be present taking into account the dead weight. Furthermore, according to the invention, due to the special design, arrangement and material selection of flexurally elastic and rigid elements 5, 6 an elastic deflection of the rod body with two-sided, end-side support under load of at least 200 mm in the respective rod center exists without a plastic deformation of the elements. 5 , 6 is given. In the material selection made in the exemplary embodiment shown, for example, under a load in the central region of 150 N, an elastic deflection of approximately 110 mm results. For example, this deflection is twice that of a solid wood pole and about 25% greater than a full plastic cross section.

The obstacle rod according to the invention acts twice energy-consuming, on the one hand by the outer shell 2, the sleeve, and on the other hand by the elastic deformability of the inner core 3. As for the relation of the flexural rigidity of the rigid elements 6 to that of the resiliently flexible elements 5, so it is advantageous if the flexural rigidity of the rigid elements 6 has at least approximately 5 times the value of the elastically bendable elements 5 in terms of length. Here, in a non-rotationally symmetrical cross-section in addition to the dynamic modulus of elasticity of the materials of the bie rigid elements 6 and the resiliently deflectable elements 5 also have to respect a geometry dependence and a directionality with respect to the acting bending force. With regard to the invention, the bending stiffness in the direction of the effect of the weight is of interest. In particular, by a different arrangement of the flexurally elastic elements 5 within the rod body 1, the elasticity and the rigidity of the obstacle rod according to the invention can be influenced. Of course, the material selection also plays a significant role. Thus, the modulus of elasticity of plastics is between 200 to 15,000 N / mm ² and in steel about 21,000 N / mm ² . For example, aluminum has an E-modulus of 50,000 N / mm ² .

In the second embodiment of the invention shown in Fig. 8 and 9 is provided that the outer sleeve 2 at least one extending in the direction of the longitudinal axis XX of the sleeve 2 and the rod body 1 recording AU2 for a particular hanging attached to the sleeve 2 obstacle element 21, such as a plank or a gate has. The receptacle AU2 of the outer sleeve 2 can advantageously be designed as a cross-section of the sleeve 2 circumferentially extending gap in which the obstacle member 21 attached, for. it is glued into it. The material of the obstruction element 21 may also be a foam, for example the above-mentioned PUR foam, preferably because of its light specific gravity. The gluing may e.g. by means of double-sided adhesive tape or in particular with a dispersion adhesive.

As shown in FIGS. 1 and 9, it can be provided that the outer sleeve 2 consists of several, in particular on the inner core 3 can be pushed, identically constructed, but possibly differently colored, sleeve parts HT2. Through the use of differently long and differently colored sleeve parts HT2, it is possible to individually design or reshape each individual obstacle rod according to the invention in a few minutes. The length LHT2 of the sleeve parts can advantageously be in the range from 50 mm to 2000 mm, preferably from 400 mm to 1500 mm. The obstacle member 21 may also be in its overall length also, preferably as well as the sleeve 2, be divided, as indicated by the vertical dashed lines in Fig. 8.

In Fig. 10, an embodiment of the formation of a plank or a gate instead of the embodiment of FIGS. 7 and 8 is shown. This is a stand-alone version of a gate 22, which can for example be composed of a 1 m long module. Such a module consists of a base frame 23, in particular of welded aluminum square profile tubes and the actual obstacle element 24 in a different design form of solid foam. This made of solid foam obstacle member 24 is coated with a plastic skin (polyurethane coating) for optical color design and to reduce the moisture absorption by weathering and by a suitable adhesive to the base frame 23, which serves for better stability of the obstacle, firmly connected. This construction reduces the risk of injury in the event of a failed jump attempt for rider and horse. In addition, the transport weight during parcour construction is reduced by at least 50% compared to conventional wooden obstacles. The foam is a polyurethane foam of appropriate composition as described for the sleeve material of the sleeve 2 according to the invention.

The rod support part 25 shown in FIG. 11 - a catching stand in the special case shown - can preferably be used in conjunction with the obstacle rods according to the invention described above, but in principle can also be used for other obstacle rods. The rod support member 25 has support members A25 for the obstacle rod and a stand S25, the support members A25 being fixed to the stand S25. The support elements A25 have substantially the shape of half rings whose unspecified inner diameter is adapted to the outer diameter of the rod D2A / D4A. The stand S25 has a jacket M25 made of a shock absorbing material and a carrier core TK25 fixed in comparison with the jacket M25. This results in similar advantages for increased safety when jumping as by the use of the rod according to the invention. For jacket M25 and carrier core TK25, the same materials can be used with advantage as for the outer sleeve 2 of the obstacle rod according to the invention or for the rigid elements 6 of the core 3 of the rod, such as. the described PUR or PA material described.

The stand S25 includes a vertical post P25, which stands on three feet F25. As can be seen by the sectional view, in particular, the post P25 the structure of sheath M25 and carrier core TK25, but the feet F25 can also be constructed.

On the rod support part 25, in particular on the jacket M25 of the stand S25 of the rod support part 25, a retaining rail H25 is formed for advantageously height-adjustable fixing of the support elements A25 for the obstacle rod. Instead of the retaining rail H25, a guide opening could also be provided, through which the support elements A25 pass, whereby they could then be fastened in the comparatively stronger carrier core TK25.

In the case of the use of foam as a material for the jacket 2 or the sleeve can advantageously be additionally provided that the sleeve surface is designed to be closed-pored or coated with a plastic skin, so that moisture absorption can be prevented by weathering. For this purpose, the initially open-cell foam of the sleeve 2 with a polyurethane liquid plastic, which is mixed with paint, sprayed (sprayed), so that a colored closed surface is formed, wherein the sprayed polyurethane plastic with the base material of the foam body of the sleeve 2 connects and forms an outer closed watertight surface. This polyurethane coating can also be realized for the obstacle part 21 or for the gate 22, as described in connection with FIGS. 9 and 10.

The invention is not limited to the illustrated embodiments, but also includes all equivalent embodiments. Thus, for example, it is possible to use the resiliently deflectable elements 5 in different ways, e.g. as coil springs, rod-like, or - like the rigid elements 6 - form disc-like.

In terms of a higher flexural elasticity of the obstacle rod according to the invention in an area in which experience has to be expected with most collisions of horse and rider with the rod, can be advantageously provided that in the region of the ends of the rod body less and / or shorter flexurally elastic elements 5 are arranged as in the middle of the rod.

In particular for the case of a similar cross-sectional design and arrangement of the rigid elements 6 and the elastically bendable elements 5, not shown, it is advantageous in terms of a coordinated bending stiffness if the dynamic elastic modulus of the material of the rigid elements 6 at least about 8 to 10 -fold value of the dynamic modulus of elasticity of the material of the elastically bendable elements 6 has. Thus, the modulus of elasticity of rubber approximates the modulus of elasticity of the materials hard rubber, wood (transverse to the fiber direction, common case of the known rod), PA (humid as indicated above in Table 1), wood (longitudinal to the fiber direction) and simultaneously glass fiber reinforced polyamide (PA 66 GF 30): 1: 10: 100: 300: 2000, wherein a particular material from this series can be used either for a flexurally elastic element 5 or for a rigid element 6 depending on its combination with another material. It should also be noted that the density of these substances, which determines the dead load of an obstacle rod according to the invention, does not deviate from one another in the same order of magnitude. Thus, even the use of certain fiber-reinforced plastics with advantageously low density even the same modulus of elasticity as steel and thus - if necessary, with a preferably adjustable length-related rod mass of about 15 g / cm to 70 g / cm, preferably from 30 g / cm to 45 g / cm - a very high bending stiffness for the rigid elements 6 can be achieved.
