Definitions
- the invention relates to a stand for a jumping obstacle, in particular for the horse jumping sport, with a support post rising from a foot and at least one support part for a jump bar or the like. Slidably guided on a vertical guide arranged on the support post and by means of a motor-driven actuator in different altitude is adjustable, wherein the actuator has a pulling member, which wraps around at least one guide wheel and at the Lastrum the at least one support part is connected.
- the obstacles used in horse jumping for jump training horses or tournaments usually consist of horizontally arranged rods, which are held by means of two standing at their right and left ends upright in the respective desired altitude.
- the stands are provided with support parts for the jump poles, which can be locked at different heights on the uprights.
- the pads In order to adjust the obstacle to different heights, the pads have been displaced by hand in most cases in headers, which are provided on one side of the stand.
- Hand placement of the support members is a cumbersome and time-consuming task that is difficult to perform by one person because it requires relieving the support members of the weight of the rod resting thereon to lock the support member to the new desired height to be able to. If the rider who is training with his horse wants to change the height of one or more obstacles during the training, he must first sit down and usually hold the horse by the rein while setting the obstacle to the new height. The training thus experiences an unwanted interruption.
- a device for setting the altitude of the jump bars bearing support parts on jump obstacle stands, with motor-driven actuators are used, with the help of which the support parts can be moved in height.
- the known device uses either a scissor or parallelogram gear mechanism for the height adjustment of the support parts or a rotatable about a vertical axis adjusting spindle with a screwed thereto nut, which is coupled to a support member and moves by turning the adjusting spindle by means of a geared motor in height and thereby raises or lowers the jump bar.
- Comparable is also a construction, as it from the EP 989 894 B1 is known.
- a generic stand for a jumping obstacle is from the WO 93/24197 is known.
- This stand has a towering from a foot support post and a support post adjustable in different altitudes support part for a jump bar, which can also be adjusted by motor. Adjusted is the support part in height by means of a pull rope, which wraps around deflecting wheels and a drive wheel and which is connected to the support part.
- the support part which carries the relatively heavy obstacle rods, due to this burden decreases in an undesirable manner, since the umlenking the guide wheels and the drive cable can slip on the drive wheel.
- the drive for the support part is open at least on one side, so that sand or other dirt and moisture can get to the drive and damage it.
- the height adjustment of the support part by means of a pull rope, which is deflected over a plurality of pulleys and connected at the bottom of the support part of the first stator.
- the support parts for the obstacle rods are moved directly from threaded spindle drives up and down.
- the object of the invention is to improve a stand for a jumping obstacle of the type mentioned in that the actuator for the support part dirt by squirting sand, water or the like. is not exposed and not only allows a positionally accurate positioning of the support member in the respective desired height, but is able to reliably maintain this height until the next adjustment.
- the actuator is at least partially disposed in a separate from at least one support member receiving chamber in the interior of the support post, wherein the actuator comprises a arranged in the receiving chamber threaded spindle and cooperating with this Buchschlitten on which the tension member zugfest is connected, and wherein the support post consists of a preferably one-sided open box section with a extending over its height partition, which is the receiving chamber of the support part or the leading vertical guide separated and open only in the region of the at least one guide wheel for the tension member is open or .
- an endless tension member for the actuator which consists for example of an elastic belt, preferably a toothed belt, can be the mechanism for raising and lowering the accommodate at least one support part in a very small space, especially in the interior of the support post, where it is taken protected.
- the spatial separation of the actuator of the or the support part (s) has the particular advantage that sand, dust and / or moisture, which one has to do regularly in jump course, can not get to the protected in the separate receiving chamber actuator received.
- the actuator comprises the arranged in the support post threaded spindle and cooperating with this, the spindle nut having pull slide on which the tension member is connected tensile strength.
- the spindle drive of the actuator can be dimensioned considerably smaller than the known from the prior art scissors or spindle gear, so that equipped with an actuator according to the invention stand also easily offset by only one person in the course or completely removed from this can.
- the Switzerlandschlitten inside the support post is thus similar to the or the Auflagerteil (s) out, which is or according to the invention on an outside of the support post arranged vertical guide is slidably / are.
- the support post according to the invention consists of a preferably open on one side box section, for example of an aluminum alloy, with a extending over its height partition, which separates the receiving chamber of the support part or this leading vertical guide and only in the region of at least one guide wheel is interrupted or open for the tension member.
- the vertical guide for the support part (s) can then be formed in this construction of the substantially over the height of the box profile extending opening on the one box profile side by the or the support part (s) are provided with lateral guide grooves, in which surround the slot-like opening laterally limiting profile edges.

- the arrangement may, for example, be made such that the components of the Actuator are mounted on the partition and the partition wall can be inserted with the assembled parts of the actuator in the longitudinal direction of the support post in the interior of arranged guide rails or pulled out again.
- the support member is connected to the pulling member by means of an overload coupling, which ensures that the stress exerted by the jump bar on the support member load, which is removed from this in the tension member, can not rise above a threshold. Rather, if the load becomes too great, for example, because a horse falls on the jump bar or about because playing children have placed themselves on the obstacle rod, the overload clutch is triggered, which causes the launched rod falls down. In this way, the maximum acting on the tension member load is limited and damage to the tension member and this actuating drive is avoided.
- the overload clutch has a retaining spring which engages a holding portion on the support member and is moved in overloading of the support member out of engagement with the holding portion, for example by a spring formed on the retaining lug against the spring action of a Cam element or an edge on the support part is pressed from a recess formed on this.
- the stand according to the invention may comprise a plurality of height-spaced from each other support parts, of which the uppermost is connected to the load strand of the tension member and the other bearing parts are coupled by means of coupling elements with each other and with the uppermost support part.
- the coupling elements may be, for example, single or multi-part coupling rods, coupling chains or coupling cables.
- a particularly advantageous embodiment is when the coupling elements consist of rigid coupling rods, the longitudinally displaceable in arranged on the support members rod guides are recorded and secured in end positions by means of end stops.
- the coupling rods give the support parts a guide in the vertical direction in that the support parts can move with their rod guides along the coupling rods slidably received therein.
- the actuator preferably has a drive motor which is at least partially received in the interior of the support post, which gives a more compact design.
- the actuator may be battery or battery operated, wherein the battery or the battery is preferably also at least partially received in the interior of the support post.
- a remote control can be used, in particular a wireless remote control, which it is the rider himself very easy to operate the actuator and thereby change the height of the obstacle in training.
- the support part (s) is displaceably guided on a vertical guide arranged on the support post.
- each stand has a control for the respective actuator and the controls in the manner of a master / Slave coupling communicate with each other. This ensures that the support parts of two stands of an obstacle on which a jump pole rests, preferably at the same time each by the same amount to move up or down and the jump bar after adjustment is still aligned horizontally and assumes no skew.
- a jumping course with at least erect two jump obstacles, the jump obstacles or the stand used therein by means of a preferably wireless remote control are remotely controllable that either individual jump obstacles or more jump obstacles can be controlled at the same time according to a predetermined plan for height adjustment of the support parts. It is thus possible, with appropriate prior programming of the remote control, not only to adjust individual, selected obstacles in the course, but it is possible to change several, in particular all obstacle course obstacles in height with just one press of a button and thus the course within a very short time for training to prepare for another difficulty level (L, M, S).

Fig. 2 to 5 provided on its side facing the jump rods 14 side 32 with a substantially over the height of the support post extending vertical guide 33, in which the holding blocks 25 of the support parts are slidably received with a sliding stone-like, projecting guide member 34.
- On the guide member 34 in turn support members 35 are releasably secured with concave support surface for the jump bars.
- the arrangement may be such that the vertical guide is closed in its regions between the guide elements 34 passing through it by a self-closing seal 37, for example a brush seal, so that the entry of sand, dust or the like into the interior of the support post effectively prevented becomes.
- a rechargeable battery 36 and a radio-remote-controlled control 38 for the drive 20 are accommodated in the interior of the support post 15.
- the battery is preferably exchangeably received in a suitable receiving pocket 40 from the outside 39 of the support post.
- the battery whose capacity is such that the actuation of the drive and its control for at least as many adjustment operations, as they can be expected during a training day, is ensured, allows the stand according to the invention in virtually every place in the training hall or set up on the training ground, so that the course can be redesigned as desired, without having to take into account whether the required power supply for the drive, for example, by external sockets is secured.

It can be seen that all dirt and moisture-sensitive components of the actuator for raising and lowering the obstacle rods are protected in the all-sided closed receiving chamber 58 are arranged.
- the drive screw 59 is essentially loaded only by a tensile force in the axial direction of the spindle, because the load transmitting organ in the form of the two drive belts 16 transmits the weight force as a pure tensile force and initiates this in a very small lateral distance from the spindle in this, so that the load on the spindle due to a tilting moment acting on it is negligible. Jerky loads that are transmitted by the traction elements are damped by the spring 57 and therefore not initiated in full strength in the spindle drive.
- the partition wall 52 is received in the box section 48 in lateral guide grooves 60, in which they can be pushed from the upper end of the box section down to the bottom.

- the arrangement is made such that the two stands 11, 12, which together with the jump poles 14 therebetween form a jumping obstacle 10, also communicate with each other in the manner of a master-slave control, which ensures that the drives 20 of both stands 11, 12 synchronously work and the corresponding support parts of the two stands are always at the same height, so that the supported with them jump bar always maintains a horizontal position.
- the use of a circulating (closed) tension member with a lower pulley is not essential, it is sufficient if the or the traction member (s) from the inside running slide up over the mounted at the upper end of the support post Deflection pulley and from this back down to the top support part extends / extend.
- the stand according to the invention can also be used for height adjustment of differently shaped obstacle elements the jump poles shown here are used, for example, for gate or fence elements, as they are occasionally built for military tests.
- As a material for the stand in particular their support post is preferably aluminum used, which provides high strength with low weight and thus favors the handling of the stand on.

Description
Die Erfindung betrifft einen Ständer für ein Sprunghindernis, insbesondere für den Pferdespringsport, mit einem von einem Fußteil aufragenden Tragpfosten und mindestens einem Auflagerteil für eine Sprungstange oder dgl., das an einer am Tragpfosten angeordneten Vertikalführung verschieblich geführt und mittels eines motorisch angetriebenen Stellantriebs in verschiedene Höhenlagen verstellbar ist , wobei der Stellantrieb ein Zugorgan aufweist, das mindestens ein Umlenkrad umschlingt und an dessen Lastrum das mindestens eine Auflagerteil angeschlossen ist.The invention relates to a stand for a jumping obstacle, in particular for the horse jumping sport, with a support post rising from a foot and at least one support part for a jump bar or the like. Slidably guided on a vertical guide arranged on the support post and by means of a motor-driven actuator in different altitude is adjustable, wherein the actuator has a pulling member, which wraps around at least one guide wheel and at the Lastrum the at least one support part is connected.
Die im Pferdespringsport zum Sprungtraining der Pferde oder bei Turnieren eingesetzten Hindernisse bestehen meist aus waagerecht angeordneten Stangen, die mittels zwei an ihren rechten und linken Enden stehenden Ständern in der jeweils gewünschten Höhenlage gehalten werden. Hierzu sind die Ständer mit Auflagerteilen für die Sprungstangen versehen, die in verschiedenen Höhen an den Ständern arretiert werden können. Um das Hindernis auf unterschiedliche Höhen einzustellen, werden die Auflagen bislang meist in Steckleisten, die an einer Seite des Ständers vorgesehen sind, in ihrer Höhe von Hand versetzt.The obstacles used in horse jumping for jump training horses or tournaments usually consist of horizontally arranged rods, which are held by means of two standing at their right and left ends upright in the respective desired altitude. For this purpose, the stands are provided with support parts for the jump poles, which can be locked at different heights on the uprights. In order to adjust the obstacle to different heights, the pads have been displaced by hand in most cases in headers, which are provided on one side of the stand.
Das Versetzen der Auflagerteile von Hand ist eine mühsame und zeitraubende Tätigkeit, die auch nur schwer von einer Person ausgeführt werden kann, denn es ist hierzu erforderlich, die Auflagerteile vom Gewicht der darauf aufliegenden Stange zu entlasten, um das Auflagerteil in der neuen gewünschten Höhe arretieren zu können. Wenn der Reiter, der mit seinem Pferd trainiert, während des Trainings die Höhe eines oder gar mehrerer Hindernisse selbst verändern will, muss er zunächst Absitzen und meist das Pferd am Zügel halten, während er das Hindernis auf die neue Höhe einrichtet. Das Training erfährt hierdurch eine unerwünschte Unterbrechung.Hand placement of the support members is a cumbersome and time-consuming task that is difficult to perform by one person because it requires relieving the support members of the weight of the rod resting thereon to lock the support member to the new desired height to be able to. If the rider who is training with his horse wants to change the height of one or more obstacles during the training, he must first sit down and usually hold the horse by the rein while setting the obstacle to the new height. The training thus experiences an unwanted interruption.
Durch die
Ein gattungsgemäßer Ständer für ein Sprunghindernis ist aus der
Bei einem aus der
Aufgabe der Erfindung ist es, einen Ständer für ein Sprunghindernis der eingangs genannten Art dahingehend zu verbessern, dass der Stellantrieb für das Auflagerteil Verschmutzungen durch aufspritzenden Sand, Wasser o.dgl. nicht ausgesetzt wird und nicht nur eine lagegenaue Positionierung des Auflagerteils in der jeweils gewünschten Höhe ermöglicht, sondern diese Höhe bis zur nächsten Verstellung zuverlässig beizuhalten vermag.The object of the invention is to improve a stand for a jumping obstacle of the type mentioned in that the actuator for the support part dirt by squirting sand, water or the like. is not exposed and not only allows a positionally accurate positioning of the support member in the respective desired height, but is able to reliably maintain this height until the next adjustment.
Diese Aufgabe wird mit der Erfindung dadurch gelöst, dass der Stellantrieb wenigstens teilweise in einer vom mindestens einen Auflagerteil getrennten Aufnahmekammer im Inneren des Tragpfostens angeordnet ist, wobei der Stellantrieb eine in der Aufnahmekammer angeordnete Gewindespindel und einen mit dieser zusammenwirkenden Zugschlitten umfasst, an dem das Zugorgan zugfest angeschlossen ist, und wobei der Tragpfosten aus einem vorzugsweise einseitig offenen Kastenprofil mit einer sich über seine Höhe erstreckenden Trennwand besteht, die die Aufnahmekammer von dem Auflagerteil bzw. der diese führenden Vertikalführung abtrennt und lediglich im Bereich des mindestens einen Umlenkrades für das Zugorgan unterbrochen oder offen ist.. Indem für den Stellantrieb ein endloses Zugorgan zum Einsatz kommt, das beispielsweise aus einem elastischen Riemen, vorzugsweise einem Zahnriemen besteht, lässt sich der Mechanismus zum Anheben und Absenken des mindestens einen Auflagerteils auf sehr engem Raum unterbringen, insbesondere im Inneren des Tragpfostens, wo er geschützt aufgenommen ist. Die räumliche Trennung des Stellantriebs von dem oder den Auflagerteil(en) hat den besonderen Vorteil, dass Sand, Staub und/oder Feuchtigkeit, womit man im Sprungparcours regelmäßig zu tun hat, nicht an den in der separaten Aufnahmekammer geschützt aufgenommenen Stellantrieb gelangen kann.This object is achieved with the invention in that the actuator is at least partially disposed in a separate from at least one support member receiving chamber in the interior of the support post, wherein the actuator comprises a arranged in the receiving chamber threaded spindle and cooperating with this Zugschlitten on which the tension member zugfest is connected, and wherein the support post consists of a preferably one-sided open box section with a extending over its height partition, which is the receiving chamber of the support part or the leading vertical guide separated and open only in the region of the at least one guide wheel for the tension member is open or .. By using an endless tension member for the actuator, which consists for example of an elastic belt, preferably a toothed belt, can be the mechanism for raising and lowering the accommodate at least one support part in a very small space, especially in the interior of the support post, where it is taken protected. The spatial separation of the actuator of the or the support part (s) has the particular advantage that sand, dust and / or moisture, which one has to do regularly in jump course, can not get to the protected in the separate receiving chamber actuator received.
Besonders vorteilhaft bei der Erfindung, dass der Stellantrieb die im Tragpfosten angeordnete Gewindespindel und den mit dieser zusammenwirkenden, die Spindelmutter aufweisenden Zugschlitten umfasst, an dem das Zugorgan zugfest angeschlossen ist. Durch diese erfindungsgemäße Konstruktion werden nämlich die Vorteile, die ein Spindeltrieb insbesondere hinsichtlich Stellgenauigkeit und (automatischer) Blockade bei Stillsetzen des Antriebs hat, mit den Vorteilen eines (oben) über ein Umlenkrad geführten Riemens kombiniert. Die Anordnung kann zweckmäßig so getroffen sein, dass der Zugschlitten an einer im Inneren des Tragpfostens angeordneten Schlittenführung höhenverschieblich geführt ist, wobei vorzugsweise das Zugorgan am Zugschlitten zwischen der Schlittenführung und der Gewindespindel angreift. Die hierdurch an dem Zugschlitten (=Spindelmutter) und damit auch an der Gewindespindel auftretenden Belastungen wirken im wesentlichen nur in deren Achsrichtung, da der Angriffspunkt der vom Zugorgan eingeleiteten Zugkraft sich in sehr geringen Abstand von der Spindelachse befindet und das aus der Zugkraft resultierende Kippmoment, das von dem Spindeltrieb aufgenommen werden muss, nur sehr gering ist. Bei Verwendung von zwei parallel laufenden Zugorganen, deren Antriebstrume im Inneren des Tragpfostens mit der Achse der Stellspindel in einer Ebene liegen, kann ein Kippmoment auf die Spindel sogar ganz vermieden werden. Da bei dieser besonders bevorzugten Antriebskonstruktion der Spindeltrieb praktisch nur in Axialrichtung durch die Auflagerkräfte belastet wird, die von den auf den Auflagerteilen aufliegenden Hindernisstangen stammen, und eine Kippmomentbelastung wegen des sehr kleinen wirksamen Hebelarms vernachlässigbar gering ist, kann der Spindeltrieb des Stellantriebs erheblich kleiner dimensioniert sein als die aus dem Stand der Technik bekannten Scheren- oder Spindelgetriebe, so dass ein mit einem erfindungsgemäßen Stellantrieb ausgerüsteter Ständer auch von nur einer Person im Parcours leicht versetzt oder aus diesem vollständig entfernt werden kann.Particularly advantageous in the invention that the actuator comprises the arranged in the support post threaded spindle and cooperating with this, the spindle nut having pull slide on which the tension member is connected tensile strength. By this construction according to the invention, namely, the advantages of a spindle drive in particular with regard to positioning accuracy and (automatic) blockade when stopping the drive, combined with the advantages of a (above) guided over a pulley belt. The arrangement may be suitably made such that the pull slide is guided in a height-displaceable manner on a slide guide arranged in the interior of the support post, the pull member preferably acting on the slide carriage between the slide guide and the threaded spindle. The thus occurring on the pull slide (= spindle nut) and thus also on the threaded spindle loads act essentially only in the axial direction, since the point of application of the pulling member introduced tensile force is located at a very small distance from the spindle axis and the resulting from the tensile force overturning moment, which must be absorbed by the spindle drive, is very low. When using two parallel-running traction elements, the drive lines are in the interior of the support post with the axis of the adjusting spindle in a plane, a tilting moment on the spindle can even be completely avoided. Since in this particularly preferred drive construction of the spindle drive is practically charged only in the axial direction by the bearing forces, which originate from resting on the support parts obstacle rods, and a Kippmomentbelastung because of the very small effective lever arm is negligible, the spindle drive of the actuator can be dimensioned considerably smaller than the known from the prior art scissors or spindle gear, so that equipped with an actuator according to the invention stand also easily offset by only one person in the course or completely removed from this can.
Der Zugschlitten im Inneren des Tragpfostens ist somit ähnlich wie das oder die Auflagerteil(e)geführt, das oder die erfindungsgemäß an einer außen am Tragpfosten angeordneten Vertikalführung verschieblich ist/sind. Der Tragpfosten besteht gemäß der Erfindung aus einem vorzugsweise einseitig offenen Kastenprofil, beispielsweise aus einer Aluminium-Legierung, mit einer sich über seine Höhe erstreckenden Trennwand , die die Aufnahmekammer von dem Auflagerteil bzw. der diese führenden Vertikalführung abtrennt und lediglich im Bereich des mindestens einen Umlenkrades für das Zugorgan unterbrochen oder offen ist. Die Vertikalführung für das bzw. die Auflagerteil(e) kann bei dieser Konstruktion dann von der sich im wesentlichen über die Höhe des Kastenprofils erstreckenden Öffnung an der einen Kastenprofilseite gebildet werden, indem das bzw. die Auflagerteil(e) mit seitlichen Führungsnuten versehen sind, in die die die schlitzartige Öffnung seitlich begrenzenden Profilränder einfassen. Besonders vorteilhaft ist es, wenn die Vertikalführung von der sich über die Höhe erstreckenden Öffnung des Kastenprofils ein Stück weit nach innen versetzt ist und beispielsweise unmittelbar vor der Trennwand ausgebildet ist, wo sie von zwei im Querschnitt etwa C-förmig ausgestalteten Führungsprofilen aus Kunststoff o.dgl. gebildet sein kann, die in an den Seitenwänden des Kastenprofils innen vorgesehenen Profilaufnahmen so gehaltert sind, dass die von ihnen gebildeten Führungsnuten nach innen offen sind und den bzw. die Halteblock/Haltebblöcke für das jeweiligen Auflagerteil führen.The Zugschlitten inside the support post is thus similar to the or the Auflagerteil (s) out, which is or according to the invention on an outside of the support post arranged vertical guide is slidably / are. The support post according to the invention consists of a preferably open on one side box section, for example of an aluminum alloy, with a extending over its height partition, which separates the receiving chamber of the support part or this leading vertical guide and only in the region of at least one guide wheel is interrupted or open for the tension member. The vertical guide for the support part (s) can then be formed in this construction of the substantially over the height of the box profile extending opening on the one box profile side by the or the support part (s) are provided with lateral guide grooves, in which surround the slot-like opening laterally limiting profile edges. It when the vertical guide is offset from the over the height extending opening of the box section a piece far inward and is formed, for example, immediately before the partition, where they are made of two in cross-section approximately C-shaped guide profiles made of plastic o. like. may be formed, which are supported in provided on the side walls of the box profile inside profile recordings so that the guide grooves formed by them are open inwards and lead the holding block / Haltebblöcke for the respective support part.
Als sehr vorteilhaft hat es sich für die Montage des Hindernisständers und die Wartung der darin eingebauten Bauelemente, insbesondere der Verschleißteile, erwiesen, wenn der Stellantrieb als Baueinheit in den Tragpfosten eingesetzt und als solche auch wieder demontierbar ist. Die Anordnung kann z.B. so getroffen sein, dass die Bauelemente des Stellantriebs an der Trennwand montiert sind und die Trennwand mit den daran montierten Teilen des Stellantriebs in Längsrichtung des Tragpfostens in dessen Inneren angeordneten Führungsleisten eingeschoben oder wieder herausgezogen werden kann.It has proven to be very advantageous for the installation of the obstacle stand and the maintenance of the built-in components, in particular the wearing parts, when the actuator is used as a unit in the support post and as such also disassembled. The arrangement may, for example, be made such that the components of the Actuator are mounted on the partition and the partition wall can be inserted with the assembled parts of the actuator in the longitudinal direction of the support post in the interior of arranged guide rails or pulled out again.
Vorzugsweise ist das Auflagerteil am Zugorgan mittels einer Überlastkupplung angeschlossen, die sicherstellt, dass die von der Sprungstange auf das Auflagerteil ausgeübte Belastung, die von diesem in das Zugorgan abgetragen wird, nicht über einen Schwellenwert hinaus ansteigen kann. Vielmehr wird, wenn die Belastung zu groß wird, beispielsweise weil ein Pferd auf die Sprungstange fällt oder etwa, weil spielende Kinder sich auf die Hindernisstange gesetzt haben, die Überlastkupplung ausgelöst, was dazu führt dass die aufgelegte Stange herab fällt. Auf diese Weise wird die auf das Zugorgan maximal wirkende Last begrenzt und eine Beschädigung des Zugorgans und des dieses betätigenden Antriebs wird vermieden. Eine kompakt bauende, zuverlässige Konstruktion erhält man insoweit, wenn die Überlastkupplung eine Haltefeder aufweist, die an einem Haltebereich am Auflagerteil angreift und bei Überbelastung des Auflagerteils außer Eingriff mit dem Haltebereich bewegt wird, beispielsweise indem eine an der Feder ausgebildete Haltenase entgegen der Federwirkung von einem Nockenelement oder einer Kante am Auflagerteil aus einer an diesem ausgebildeten Ausnehmung gedrückt wird.Preferably, the support member is connected to the pulling member by means of an overload coupling, which ensures that the stress exerted by the jump bar on the support member load, which is removed from this in the tension member, can not rise above a threshold. Rather, if the load becomes too great, for example, because a horse falls on the jump bar or about because playing children have placed themselves on the obstacle rod, the overload clutch is triggered, which causes the launched rod falls down. In this way, the maximum acting on the tension member load is limited and damage to the tension member and this actuating drive is avoided. A compact construction, reliable construction is obtained so far, if the overload clutch has a retaining spring which engages a holding portion on the support member and is moved in overloading of the support member out of engagement with the holding portion, for example by a spring formed on the retaining lug against the spring action of a Cam element or an edge on the support part is pressed from a recess formed on this.
Der Ständer nach der Erfindung kann mehrere, in Höhenabstand voneinander vorgesehene Auflagerteile aufweisen, von denen das oberste am Lasttrum des Zugorgans angeschlossen ist und die anderen Auflagerteile mittels Koppelelementen miteinander und mit dem obersten Auflagerteil gekoppelt sind. Bei Betätigung des Stellantriebes und Umlaufen des Zugorgans zum Anheben des obersten Auflagerteils und damit der darauf aufliegenden Sprungstange werden die darunter angeordneten Auflagerteile über die Koppelelemente ebenfalls mit angehoben, sobald die Kopplung erfolgt ist. Bei den Koppelelementen kann es sich beispielsweise um ein- oder mehrteilige Koppelstangen, um Koppelketten oder Koppelseile handeln. Eine besonders vorteilhafte Ausgestaltung ist es, wenn die Koppelelemente aus starren Koppelstangen bestehen, die in an den Auflagerteilen angeordneten Stangenführungen längsverschieblich aufgenommen sind und in Endpositionen mittels Endanschlägen gesichert sind. Die Koppelstangen geben nämlich bei dieser Ausgestaltung den Auflagerteilen eine Führung in Vertikalrichtung, indem sich die Auflagerteile mit ihren Stangenführungen entlang der darin gleitend aufgenommenen Koppelstangen bewegen können.The stand according to the invention may comprise a plurality of height-spaced from each other support parts, of which the uppermost is connected to the load strand of the tension member and the other bearing parts are coupled by means of coupling elements with each other and with the uppermost support part. Upon actuation of the actuator and circulation of the tension member for lifting the uppermost support part and thus the jump pole resting thereon, the support parts arranged underneath are also raised via the coupling elements as soon as the coupling has taken place. The coupling elements may be, for example, single or multi-part coupling rods, coupling chains or coupling cables. A particularly advantageous embodiment is when the coupling elements consist of rigid coupling rods, the longitudinally displaceable in arranged on the support members rod guides are recorded and secured in end positions by means of end stops. In this embodiment, the coupling rods give the support parts a guide in the vertical direction in that the support parts can move with their rod guides along the coupling rods slidably received therein.
Der Stellantrieb weist vorzugsweise einen Antriebsmotor auf, der wenigstens teilweise im Inneren des Tragpfostens aufgenommen ist, womit man eine noch kompaktere Bauweise erhält. Der Stellantrieb kann batterie- oder akkubetrieben sein, wobei die Batterie oder der Akku vorzugsweise ebenfalls wenigstens teilweise im Inneren des Tragpfostens aufgenommen ist.The actuator preferably has a drive motor which is at least partially received in the interior of the support post, which gives a more compact design. The actuator may be battery or battery operated, wherein the battery or the battery is preferably also at least partially received in the interior of the support post.
Zur Ansteuerung des Stellantriebs kann eine Fernsteuerung zum Einsatz kommen, insbesondere eine kabellose Fernsteuerung, womit es auch dem Reiter selbst sehr einfach möglich ist, den Stellantrieb zu betätigen und hierdurch die Höhe des Hindernisses im Training zu verändern. Um die Stabilität des Mechanismus noch weiter zu verbessern, hat es sich als vorteilhaft erwiesen, wenn das oder die Auflagerteil(e) an einer am Tragpfosten angeordneten Vertikalführung verschieblich geführt ist/sind. Damit sich die einmal eingestellte Höhe des Hindernisses nicht von selbst verstellen kann, ist es zweckmäßig, wenn der Stellantrieb in den gewählten Höhenlagen des oder der Auflagerteil(e) verriegelbar ist.To control the actuator, a remote control can be used, in particular a wireless remote control, which it is the rider himself very easy to operate the actuator and thereby change the height of the obstacle in training. In order to further improve the stability of the mechanism, it has proved to be advantageous if the support part (s) is displaceably guided on a vertical guide arranged on the support post. Thus, once the set height of the obstacle can not adjust by itself, it is useful if the actuator in the selected heights of the or the support part (s) can be locked.
Bei einem Sprunghindernis insbesondere für den Pferdespringsport mit zwei Ständern der erfindungsgemäßen Art ist es vorteilhaft, wenn die Stellantriebe für die Auflagerteile der Ständer miteinander synchronisiert sind, wozu in bevorzugter Weiterbildung jeder Ständer eine Steuerung für den jeweiligen Stellantrieb hat und die Steuerungen nach Art einer Master/Slave-Kopplung miteinander kommunizieren. Hierdurch wird sichergestellt, dass die Auflagerteile von zwei Ständern eines Hindernisses, auf denen eine Sprungstange aufliegt, vorzugsweise zeitgleich jeweils um den gleichen Betrag nach oben oder unten verfahren werden und die Sprungstange nach der Verstellung weiterhin horizontal ausgerichtet ist und keine Schräglage einnimmt. Mit der Erfindung lässt sich in besonders vorteilhafter Weise ein Sprungparcours mit mindestens zwei Sprunghindernissen errichten, wobei die Sprunghindernisse bzw. die darin zum Einsatz kommenden Ständer mittels einer vorzugsweise kabellosen Fernsteuerung so fernsteuerbar sind, dass wahlweise einzelne Sprunghindernisse oder mehrere Sprunghindernisse zeitgleich gemäß einem vorher festgelegten Plan zur Höhenverstellung der Auflagerteile ansteuerbar sind. Man kann also bei entsprechender vorheriger Programmierung der Fernsteuerung nicht nur einzelne, ausgewählte Hindernisse im Parcours verstellen, sondern es ist möglich, mit nur einem Knopfdruck mehrere, insbesondere alle Parcours-Hindernisse in der Höhe zu verändern und damit den Parcours innerhalb kürzester Zeit für das Training einer anderen Schwierigkeitsstufe (L-, M-, S-Springen) vorzubereiten.In a jump obstacle in particular for the horse jumping sport with two stands of the type according to the invention, it is advantageous if the actuators for the support parts of the stand are synchronized with each other, for which purpose in a preferred development each stand has a control for the respective actuator and the controls in the manner of a master / Slave coupling communicate with each other. This ensures that the support parts of two stands of an obstacle on which a jump pole rests, preferably at the same time each by the same amount to move up or down and the jump bar after adjustment is still aligned horizontally and assumes no skew. With the invention can be in a particularly advantageous manner, a jumping course with at least erect two jump obstacles, the jump obstacles or the stand used therein by means of a preferably wireless remote control are remotely controllable that either individual jump obstacles or more jump obstacles can be controlled at the same time according to a predetermined plan for height adjustment of the support parts. It is thus possible, with appropriate prior programming of the remote control, not only to adjust individual, selected obstacles in the course, but it is possible to change several, in particular all obstacle course obstacles in height with just one press of a button and thus the course within a very short time for training to prepare for another difficulty level (L, M, S).

Von den vier Auflagerteilen ist das oberste 13a an dem näher zur Ständerinnenseite verlaufenden Last- oder Abtriebstrum 24 des Zugorgans mit Hilfe einer Überlastkupplung 40 angeschlossen, die im Detail in
Die unteren Auflagerteile 13b bis 13d haben ähnliche Halteblöcke 25', allerdings sind diese etwas schmaler als der oberste Halteblock 25a gestaltet, so dass sie nicht in Kontakt mit dem Lasttrum 24 des Zugorgans 16 kommen, sondern einen Abstand von diesem halten, wie dies beispielsweise bei 27 in
Der Tragpfosten 15 ist in der ersten Ausführungsform gem.
Neben dem Antrieb 20 und dem umlaufenden Zugorgan 16 nebst zugehörigen Umlenk-, Antriebs- und Anpressrollen ist im Inneren des Tragpfostens 15 noch ein wieder aufladbarer Akku 36 sowie eine Funk-fernsteuerbare Steuerung 38 für den Antrieb 20 aufgenommen. Der Akku ist dabei vorzugsweise von der Außenseite 39 des Tragpfostens austauschbar in einer passenden Aufnahmetasche 40 aufgenommen. Der Akku, dessen Kapazität so bemessen ist, dass damit die Betätigung des Antriebs und dessen Steuerung für zumindest so viele Verstellvorgänge, wie sie während eines Trainingstages erwartet werden können, sichergestellt ist, ermöglicht es, den erfindungsgemäßen Ständer an praktisch jedem Ort in der Trainingshalle oder auf dem Trainingsplatz aufzustellen, so dass der Parcours beliebig umgestaltet werden kann, ohne dass darauf Rücksicht genommen werden muss, ob die erforderliche Energieversorgung für den Antrieb beispielsweise durch externe Steckdosen gesichert ist.In addition to the
Auch der in den
Man erkennt, dass der Tragpfosten bei dem zweiten Ausführungsbeispiel ein an einer Längsseite ein Stück weit nach innen eingezogenen und dort über die Höhe des Hubweges schlitzartig offenes Kastenprofil 48 aufweist, bei dem es sich um ein Aluminiumprofil handelt. Die mit der schlitzartigen Öffnung 49 versehene, im Querschnitt (
An der Rückseite des in der Zeichnung gezeigten Halteblocks 25 für das oberste Auflagerteil des Ständers sind an dessen beiden Seiten zwei Antriebsriemen 16 a, b fest angeschlossen und nach oben im Tragpfosten geführt, wo sie genau wie beim oben beschriebenen Ständer über Umlenkrollen (hier nicht dargestellt) um 180° wieder nach unten umgelenkt werden. Dabei ist die Anordnung so getroffen, dass die umgelenkten (inneren) Abschnitte 22 der Antriebsriemen 16 von deren äußeren (Last-)Trumen 24 durch eine im Kastenprofil 48 angeordnete Trennwand 52 getrennt angeordnet sind. Die innen, also hinter der Trennwand verlaufenden Abschnitte 22 der Antriebsriemen 16 sind an einem im Inneren des Kastenprofils 48 entlang einer Schlittenführung 53 vertikal beweglichen Zugschlitten 54 zugfest angeschlossen. Der Zugschlitten 54 ist mit einem Haltebügel 55 für eine Spindelmutter 56 versehen, die sich am unteren Schenkel 55 a des Haltebügels über eine Schraubendruckfeder 57 abstützt. Die Spindelmutter 56 wiederum kämmt mit einer im Inneren der vom Kastenprofil 48 und der Trennwand 52 begrenzten Aufnahmekammer 58 angeordneten Gewindespindel 59, die von einem am oberen Ende der Spindel angekoppelten Getriebemotor 20 zum Heben bzw. Senken des Zugschlittens rechts- oder linksläufig gedreht werden kann.
Man erkennt, dass alle schmutz- und feuchtigkeitsempfindlichen Bauteile des Stellantriebs zum Heben und Absenken der Hindernisstangen geschützt in der allseitig geschlossenen Aufnahmekammer 58 angeordnet sind. So kann beispielsweise Sand, der auf der Seite der schlitzartigen Öffnung 49 an den Hindernisständer spritzt, nicht an die schmutzempfindlichen Teile des Antriebs gelangen. Selbst bei einer großen auf die Auflagerteile wirkenden Belastung beispielsweise durch die Verwendung von vergleichsweise schweren Holzstangen als Hindernisse wird die Antriebs-Gewindespindel 59 im wesentlichen nur durch eine Zugkraft in Axialrichtung der Spindel belastet, denn das die Last übertragende Organ in Form der beiden Antriebsriemen 16 überträgt die Gewichtskraft als reine Zugkraft und leitet diese in sehr geringem seitlichen Abstand von der Spindel in diese ein, so dass die Belastung der Spindel infolge eines auf sie wirkenden Kippmoments vernachlässigbar gering ist. Stoßartige Belastungen, die von den Zugorganen übertragen werden, werden durch die Feder 57 gedämpft und somit jedenfalls nicht in voller Stärke in den Spindeltrieb eingeleitet.At the back of the holding
It can be seen that all dirt and moisture-sensitive components of the actuator for raising and lowering the obstacle rods are protected in the all-sided closed receiving
Die Trennwand 52 ist im Kastenprofil 48 in seitlichen Führungsnuten 60 aufgenommen, in die sie vom oberen Ende des Kastenprofils bis nach unten hineingeschoben werden kann. Die Anordnung ist so getroffen, dass die Bestandteile des Stellantriebs an der Vorder- oder Rückseite der Trennwand montiert werden und diese Baueinheit dann nach einem außerhalb des Kastenprofils durchführbaren Funktionstest vom oberen Ende des Tragpfostens in das Kastenprofil eingeschoben werden kann und sich hierbei die rundherum geschlossene Aufnahmekammer ausbildet. Eine dann von oben auf den Pfosten aufgesetzte Abdeckkappe (nicht dargestellt) verhindert den Eintritt von Schutz und Wasser auch von der Oberseite.The
Wie bereits angedeutet, erfolgt die Ansteuerung des Antriebs zum Anheben oder Absenken der Auflagerteile und damit der darauf aufliegenden Sprungstangen mit Hilfe einer Funk-Fernsteuerung (nicht dargestellt), die vom Sprungtrainer oder vom Reiter selbst betätigt werden kann. Die Anordnung ist dabei so getroffen, dass die zwei Ständer 11, 12, die gemeinsam mit den dazwischen liegenden Sprungstangen 14 ein Sprunghindernis 10 bilden, auch untereinander nach Art einer Master-Slave-Steuerung kommunizieren, wodurch sichergestellt ist, dass die Antriebe 20 beider Ständer 11, 12 synchron arbeiten und sich die einander entsprechenden Auflagerteile der beiden Ständer immer auf derselben Höhe befinden, so dass die mit ihnen unterstützte Sprungstange immer eine waagerechte Lage beibehält.As already indicated, the drive of the drive for raising or lowering the support parts and thus the jump poles resting thereon by means of a radio remote control (not shown), which can be operated by the jump trainer or the rider itself. The arrangement is made such that the two stands 11, 12, which together with the
Die Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsbeispiele beschränkt, sondern es sind verschiedene Änderungen und Ergänzungen denkbar, ohne den Rahmen der Erfindung zu verlassen. So können beispielsweise anstelle der starren Koppelstangen flexible Koppelseile die übereinanderliegenden Auflagerteile 13a bis d untereinander verbinden. Anstelle eines oder zweier umlaufender (Zahn-)Riemen kann als Zugorgan auch eine Kette Verwendung finden, beispielsweise eine Laschenkette, wie sie auch für den Antrieb von Fahrrädern eingesetzt wird. Insbesondere bei dem zweiten Ausführungsbeispiel ist die Verwendung eines umlaufenden (geschlossenen) Zugorgans mit einer unteren Umlenkrolle nicht unbedingt erforderlich, es reicht auch aus, wenn sich das oder die Zugorgan(e) vom innen laufenden Zugschlitten nach oben über die am oberen Ende des Tragpfostens gelagerte Umlenkrolle und von dieser wieder hinab bis zum obersten Auflagerteil erstreckt/erstrecken. Die erfindungsgemäßen Ständer können auch zur Höhenverstellung von anders gestalteten Hinderniselementen anstelle der hier dargestellten Sprungstangen Verwendung finden, beispielsweise für Gatter- oder Zaunelemente, wie sie gelegentlich für Military-Prüfungen aufgebaut werden. Als Material für die Ständer, insbesondere deren Tragpfosten kommt bevorzugt Aluminium zum Einsatz, das eine hohe Festigkeit bei gleichzeitig geringem Gewicht bietet und somit die Handhabbarkeit der Ständer weiter begünstigt.The invention is not limited to the illustrated and described embodiments, but various changes and additions are conceivable without departing from the scope of the invention. Thus, for example, instead of the rigid coupling rods flexible coupling ropes connect the superimposed
