Shut-off bar for a shut-off device, in particular for escape animals such as horses

description

The invention relates to a shut-off rod for a shut-off device, in particular for escape animals such as horses, wherein the shut-off device has two spaced apart and a passage limiting boundary elements, where the Absperrstange fastened and thus the passage is lockable, wherein the shut-off rod has an elongated body, at the both ends locking elements are arranged, by which a knurled engagement of the shut-off rod with the two limiting elements of the shut-off device can be produced. Such shut-off devices are known and z. B. used in training equipment, pens or animal transporters to a passage through which the animal z. B. in the training device or the playpen, etc. can be performed to close. DE 202 15 987 U1 describes a training device for horses, which has a motorized with adjustable speed treadmill that is arranged in a stationary frame. The frame has on either side of the treadmill boundary walls, said boundary walls consist of a rigid tube frame with vertical posts and these connecting cross struts. As a result, the horse can be led over a first ramp for training on the treadmill and be guided down again after its completion by a second ramp. In order to prevent the horse from leaving the exerciser during exercise, it is envisaged that the access and exit of the exerciser will be blocked by stop rods to prevent the horse from inadvertently leaving the exerciser in either the forward or reverse direction. For this purpose, the procedure is usually such that the two adjoining the treadmill racks are closed at their front and rear posts functioning as delimiting elements of the shut-off device, each with a shut-off bar extending transversely to the extension direction of the tubular frame and connecting the two posts of the two tube racks. This is done in such a way that a rigid shut-off rod is inserted into a corresponding holder of the posts and thus the horse is trapped in the training device. As a result of the rigid formation of the Absperrstangen so the horse can leave the training device neither in the forward direction nor in the reverse direction.

Horses are known to be flight animals, that is, they try to evade a seemingly threatening situation by fleeing. If the horse in the training device is startled, it tries to leave the training device. This is not possible for him by the two Absperrstangen in the forward direction and in the reverse direction. Therefore, horses try to jump over these shut-off bars, which they rarely succeed, as they do not the required start-up is available. This requires that the horses then inevitably fall on the rigid locking bar, which can lead to serious injury to the animal and damage to the training device.

It is an object of the present invention to develop a shut-off rod for a shut-off device of the type mentioned in such a way that the shut-off rod according to the invention has a "panic release", so that in this case the shut-off function caused by the shut-off of the shut-off can be canceled.

This object is achieved in that the shut-off rod has a spring means by which at least one locking element can be acted upon by a spring force, and that the characteristic of the spring means is selected such that the force exerted by the spring means on the at least one locking element spring force within a transition region goes from a first spring force in a higher second spring force.

By means of the measure according to the invention, a shut-off rod is created in an advantageous manner, which automatically moves out of the guides of the shut-off device receiving it when force is applied in a direction orthogonal to it. The inventively provided characteristic of the spring device causes the inventive shut-off rod easily inserted into this guide and the shut-off can be locked securely therein, while a safe triggering of the same is particularly possible in the case of a "panic" of the user locked by the shut-off.

An advantageous development of the invention provides that the spring device of the shut-off rod has a first spring element with a high rigidity and at least one further spring element with a low rigidity. By such a configuration, the above-mentioned characteristic can be easily realized.

A further advantageous embodiment of the invention provides that the spring element of the spring device is designed in two parts, and that each of the two partial spring elements is arranged in the end region of the base body. Such a measure is particularly advantageous in the case of a shut-off rod having two displaceable blocking elements, since it is then not necessary for the first spring element to extend over the entire axial course of the main body.

Further advantageous developments of the invention are the subject of the dependent claims.

Further details and advantages of the invention can be found in the embodiments, which are described below with reference to the figures. Show it:

Figures 3a and 3b: a third embodiment of a shut-off device with a second embodiment of a shut-off rod along a section AA of Figure 3b or BB of Figure 3b and

Figures 4a and 4b: a fourth embodiment of a shut-off device with a second embodiment of a shut-off along a section A-A of Figure 4b and B-B of Figure 4a.

Figures 1a and 1b show a first embodiment of a generally designated 1 shut-off device, which is particularly suitable for training equipment for horses, horse transporters, horse stables, etc. Of course, the field of application of the shut-off device 1 is not limited to horses or other escape animals. For ease of description, however, it is assumed below that the described shut-off devices 1 are intended for use in horses. However, this does not limit the generality of the following consideration, as the person skilled in the art is aware of how he has to adapt the shut-off devices described for a specific purpose.

The shut-off device 1 shown in Figures 1a and 1b is basically divided into a shut-off rod 10 shown in Figure 1a and a cooperating with them holder 20, which has two acting as delimiting the shut-off device 1 posts 20a and 20b, in which the shut-off rod 10 is inserted. As can be seen from FIG. 1a, the shut-off rod 10 has an elongate main body 11, which is configured here in a tubular manner. At its two ends 11a and 11b of the main body 11 of the shut-off rod 10 each a displaceable in the axial direction locking element 12a, 12b arranged, which are acted upon by a arranged in the main body 11a spring means 13, so that the locking elements 12a, 12b at a corresponding application of force in the interior of the main body 11 of the shut-off rod 10 can retreat. The spring device has a progressive characteristic, such that a retraction of the locking elements 12a, 12b into the interior of the base body 11 is initially opposed only a small resistance, while further moving back the locking elements 12a, 12b only by overcoming a significantly higher counteracting force of Spring device 13 is possible. It is preferred here that the characteristic curve of the spring device 13 is approximately a step function, ie that the force exerted by the spring device 13 on the blocking elements 12a, 12b first preferably linear and then - idealized - at a jump point or within a jump range in one significantly higher, again preferably linearly extending force passes. This configuration of the spring device 13 is achieved - as will be described below - achieved that the described shut-off rod 10 can be easily used in guides 21 a, 21 b of the posts 20 a, 20 b of the holder 20, but that - if the shut-off rod 10 with a greater force is applied, as it is z. B. is the case when a horse jumps on the shut-off rod 10 - the clamping of the shut-off rod 10 in the guides 21 a, 21 b of the posts 20 a, 20 b of the holder 20 is released and the shut-off rod 10 falls out of the holder 20 when with a such a large force is applied. The shut-off rod 10 thus realizes a kind of "panic function", ie with only a small application of force, it securely locks the passage delimited by the two posts 20a, 20b, while it releases the passage in the event of a large force application.

In order to realize this characteristic, the spring device 13 has a first spring element 14, at the ends 14a and 14b of which a respective spring plate 15a, 15b is arranged, against which in each case a second spring element 16a, 16b is supported. Each of the two second spring elements 16a, 16b acts on the blocking element 12a, 12b assigned to it. The first spring element 14 has a greater rigidity than the two second spring element 16a, 16b connected in series with it. Apply one or both of the blocking elements 12a, 12b with a force acting opposite to the spring force of the spring device 13, this results in that first of all one or both of the second spring elements 16a, 16b are compressed, resulting in a corresponding retreat of the one or more locking elements 12a, 12b. If the force acting on the two blocking elements 12a, 12b can no longer be compensated by a further compression of the second spring elements 16a, 16b, this will cause the first spring element 14 of the spring device 13 to be compressed so that the blocking elements 12a, 12b as a result of the force applied to them can retreat. The different rigidity of the first spring element 14 and the two second spring elements 16a, 16b now requires that only a relatively small force is initially required to lead to a retreat of the locking elements 12a, 12b, while the for a further return movement of the locking elements 12a, 12b applied force due to the higher rigidity of the first spring element 14 is significantly larger.

In order to achieve a limitation of the longitudinal extent of the first spring element 14 of the spring device 13, which is designed as a compression spring, it is provided that the spring plates 15a, 15b respectively abut against a stop 17a, 17b of the main body 11 of the shut-off rod 10. For the same purpose, acted upon by the second spring elements 16a, 16b locking elements 12a, 12b at its rear end in each case a stop element 18a, 18b, which cooperates with a further stop 19a, 19b of the base body 11, which in turn is achieved by the Effect of the spring means 13, the two locking elements 12a, 12b protrude only by a defined path from the main body 11 of the shut-off rod 10. As can be seen from FIG. 1, an insertion region 22 of the guides 21a, 21b preferably expands, which facilitates easier insertion of the blocking elements 12a, 12b into the insertion regions 22a, 22b of the guide 21a, 21b. Furthermore, it is again preferably provided that the insertion regions 22a, 22b also widen in a direction orthogonal to the plane of the drawing of FIG. 1b so that insertion bevels are formed in the insertion regions 22a, 22b , wherein it is preferred that their depth at the beginning of the insertion portions 22a, 22b is dimensioned such that the locking elements 12a, 12b as easily as possible - limited by their abutting stops 19a, 19b stop elements 18a, 18b - in the insertion areas 22a , 22b can be used. Further advancement of the shut-off rod 10 into the insertion regions 22a, 22b now causes, due to the insertion bevels present there, that the blocking elements 12a, 12b are subjected to force by this forward movement and retreat into the interior of the main body 11 against the action of the second spring elements 16a, 16b. At the end of the insertion regions 22a, 22b against the guide 21a, 21b in blocking regions 23a, 23b, which - as shown in FIG. 1a - preferably have a constant depth in their upper region. These upper regions of the blocking regions 23a, 23b pass into depressions 24a, 24b, the depth of which is dimensioned such that in this position of the blocking rod 10 shown in FIG. 1a a secure locking of the blocking rod 10 in the guides 21a, 21b of the posts 20a 20b of the support 20: The walls 25a, 25b of the guides 21a, 21b delimiting posts 20a, 20b prevent the blocking rod 20 from deflecting in a direction orthogonal thereto, so that the blocking rod 10 in conjunction with the Holder 20 is blocked by the posts 20 a, 20 b limited passage. For the training device for horses described above, this means that the front and rear passage of the training device is closed by the shut-off rods 10 arranged orthogonally to the running direction of the treadmill.

Device now in the training device in panic horse and tries to escape from the training device by jumping over the shut-off rod 10 and thereby crashes on this, it now leads in an advantageous manner to trigger the shut-off rod 10: As from 1a, the guides 21a, 21b each have an outlet bevel 25a, 25b below their depressions 24a, 24b. Now, the shut-off rod 10 in a direction orthogonal to it Y - z. B. by the impact of a horse - kraftbeauf- strikes, this force acting in the Y direction causes sufficient magnitude that the blocking elements 12a, 12b can recede against the spring force of the first spring element 14 through the outlet slopes 25a, 25b. The spring plates 15a, 15b are acted upon either by the completely compressed second spring elements 16a, 16b or by the lower end of the blocking elements 12a, 12b, which leads to a compression of the first spring element 14 of the spring device 13. If the force acting in the Y-direction now exceeds the release force of the shut-off rod 10, this results in the locking elements 12a, 12b retreating into the interior of the main body 11 as a result of their application and the shut-off rod 10 continues to move downwards until it stops a trigger point 26 of the guide 21a, 21b slides out of the holder 20, whereby then the obstructed by her passage is released.

By a corresponding determination of the stiffness of the first and the second spring elements 14, 16a, 16b, it is thus easily possible, on the one hand a simple insertion of the shut-off rod 10 in the holder 20 - this insertion takes place only against the action of the weaker second spring elements 16a, 16b - and with a sufficiently large application of force reliable triggering of the shut-off rod 10 - this is the rigidity of the first spring element 14 decisive - to achieve. The described shut-off rod 10 thus has a "panic function", by which the shut-off of the shut-off device 1 can be canceled.

In Figures 2a and 2b, only a second embodiment of a shut-off device 1 is shown, wherein the shut-off rod 10 is formed as well as the shut-off rod 10 of the first embodiment and will therefore not be described in detail. The essential difference between the first and second embodiments is now in the formation of the guides 21a, 12b of the holder 20: While the guides 21a, 21b of the first embodiment have an angled shape such that the insertion portions 22a, 22b and the holding portions 23a, 23b a - preferably blunt - angle Close, in the guides 21a, 21b of the second embodiment, the insertion portions 22a, 22b and the holding portions 23a, 23b are substantially in line. Such a configuration is particularly advantageous if the receiving rod 10 in the holder 20 is not - as in the first embodiment - to be used from the side, but from above.

In the figures 3a and 3b, a third embodiment of a shut-off device 1 is shown, wherein the formation of the shut-off rod 10 from that of the first embodiment differs, the holder 20, however, are formed as in the first embodiment and are therefore not described in detail. As can be seen from FIG. 3 a, the spring element corresponding to the first spring element 14 is now formed by two spring elements 14 a, 14 b. This has the advantage that the first spring element 14 does not have to extend over the entire axial course of the main body 11 of the shut-off rod 10, but that it is provided that the first spring elements 14a and 14b are arranged only in the end regions of the main body 10. The main body 11 then has two spring platforms 14a ¹ , 14b ', on which the first ends of the first spring elements 14a, 14b are supported.

FIGS. 4a and 4b now show a fourth exemplary embodiment of a shut-off device 1, wherein the shut-off rod 10 is that of the third exemplary embodiment and the holder 20 is that of the second exemplary embodiment, so that the fourth exemplary embodiment no longer has to be described in detail.

In the above description, it has been assumed that a respective displaceable blocking element 12a, 12b is arranged at both ends of the blocking rod 10. It may well be sufficient for a number of applications that only one of the two locking elements 12a, 12b is acted upon by the spring means 13, that is, that the other blocking element, for. B. the blocking element 12 b is rigidly arranged in the shut-off rod 10, so that the nik function described Absperrstange 10 only by the other, then spring-loaded locking element 12a is achieved.

In this respect, it is not necessary that both locking elements 12a, 12b are moved back into the interior of the shut-off rod. It is Z. B. also possible that one of the locking elements 12a, 12b, is designed as a joint, which is connected to a corresponding holder in one of the posts 20a, 20b of the shut-off device 1, so that the release of the shut-off rod 10 then by a backward movement of the other blocking element is effected and after triggering the shut-off rod 10, this simply hangs down on the joint.

In the above description, it has further been assumed that the spring elements 14, 14a, 14b, 16a, 16b are formed by springs. But this is not mandatory. It is also possible, one or more of these components by the same effect components such. As gas or hydraulic cylinder to replace.

Furthermore, it can be provided that on the outside of the main body 11 slots (not shown) are mounted, in which a guide element is arranged, by means of which the second spring elements 16a, 16b can be moved back during insertion. As a result, easier insertion of the shut-off rod 10 in the holder 20 is possible.

In the foregoing description, it has been further assumed that the restriction members of the holder 20 are formed by posts 20a, 20b. However, the term "limiting elements" is to be understood broadly, since the described shut-off rod 10 and the shut-off device 1 is not limited to such a configuration., For example, it is also possible that the "posts" by rigid walls of a passage such , B. the two side struts of a door frame, are formed.
