Spur (1) comprising a holding element (3), a pin (5) arranged on the holding element (3) and a spur element (7) arranged on the end of the pin (5), characterized in that the spur element (7) is rotatable about a longitudinal axis (A) of the pin (5).

Description

The present invention relates to a spur according to the preamble of claim 1, which can be used in equestrian sports.

Known spurs 1 from the art have a holding element 3, a pin 5 arranged on the holding element 3 and a spur element 7 arranged on the end 5 of the pin 5. A spur 1 is an aid that is used for stimulating and encouraging a horse and for strengthening and refining the leg support, for example for driving the horse. The known from the prior art spurs 1, for example, with a headband 3 and attached to the headband 3 straps or attached directly to a riding boot. In this configuration, the pin 5 arranged on the retaining bracket 3 or directly on the boot extends in the rearward direction, wherein, for example, a thickening is arranged as the spur element 7 on the pin end.

From the prior art, it is also known to perform the pin 5 end fork-shaped and attach a spur as spur element 7 in this fork by means of a thru-axle. As an alternative to a star wheel 7 also cylindrical spur elements 7 are known, which are also fixed by means of a plug-in axis end to the pin 5. Exemplary embodiments of such spurs 1 according to the prior art are in the FIGS. 7a to 7c shown.

On the embodiments known from the prior art, it is disadvantageous that they are either rigid ( Figure 7a ) or the spur elements 7 rotate in one direction, which is not adapted to the typical foot movement of the rider during spore use. In the spore insert, the foot located in the stirrup is typically applied in the heel region to the ribbed arch of the horse and moved in a slight up and down movement, ie in the vertical direction. Although typical spur wheels can perform a rolling movement on the abdomen of the horse in the vertical direction, by the bifurcated design of the pin 5, but it is often the case that not the spur wheel but the end of the pin 5 comes to rest on the equine abdomen.

When roller-shaped spur elements 7 of the pin 5 is also performed either forked and the spur element 7 sits between the two arms of this fork or corresponding roller elements are arranged above and below the pin 5. A rolling movement can take place in these elements only in the horizontal direction.

All of the above-described embodiments of the prior art thus have the disadvantage that they are not adapted to the typical equestrian movement when using the spores and continue to cause injuries in horses, for example, by hooking the spur elements in the horse's skin.

It is the object of the present invention to develop the known from the prior art spurs so that a smooth use is possible and injury to the horse can be largely avoided already due to the construction of the spores.

This object is achieved by a spur having the features of patent claim 1. Advantageous developments are the subject of dependent claims.

A spur according to the invention is provided with a holding element, a spigot arranged on the holding element and a spur element arranged endwise on the spigot and designed such that the spur element is designed to be rotatable about a longitudinal axis of the spigot.

Characterized in that the spur element is designed to be rotatable about a longitudinal axis of the pin is achieved that the spur element can roll when using the spores on the stomach or the flank of the horse along in the vertical direction. It is thus avoided in particular a hooking of the spur element in the skin of the horse, so that injuries to the horse can be excluded thereby. By an adapted size of the spore element, in particular in its diameter perpendicular to the axis of rotation particularly gentle spores are formed. The larger the diameter of the spur member is chosen the gentler is the effect to be achieved.

A diameter of the spur element is preferably between 8 mm and 25 mm, more preferably 10 mm and 20 mm.

It should be noted at this point that a spur according to the invention both on a bracket, as in the prior art is most common as well as directly attached to a boot.

A further improvement of the rolling properties of the spur element is achieved if this is designed substantially as a rotationally symmetrical body. By a rotationally symmetric Training the spur elements force differences in different positions of the spur element are avoided and an effective rolling is achieved.

The spur element can for example be designed as a ball, roller, wheel or substantially drop, roller or truncated cone. All of the abovementioned forms can realize the advantages according to the invention, with a spherical design of the spur element being particularly preferred both in terms of production technology and its effect.

The spur element preferably has a bore, in particular a blind hole, in which engages the pin for supporting the spur element. Alternatively, a spine element encompassing the bracket may be provided so that storage via a plug pin can be done, which may be additionally or alternatively secured with a nut.

In order to ensure easy rolling of the spur element when using the spurs, the spur element is preferably mounted on the spigot by means of a friction reducing bearing. Preferably, the bearing is self-lubricating, in particular self-lubricating plastics, for example. Tribopolymere, are suitable as a material.

The bearing may be formed, for example, as a ball or roller bearings or as plain bearings. Bearings are particularly well suited for the intended use, since they are less susceptible to interference and easy to clean. This is particularly advantageous because when used in equitation with a pollution, for example by sand or other particles too is calculated and therefore a simple cleanability for the practical use of high importance.

The use of a sliding bearing can also reduce a size and manufacturing costs can be reduced.

In a design of the bearing as a sliding bearing, this may in particular have a sliding bush, which preferably sits in the spore element. A particularly simple attachment of the sliding bush in the spore element can be achieved if the sliding bush is pressed into the spore element, glued or screwed. This sliding bush can then cooperate with a sliding surface formed on the journal, so that an effective reduction of the friction between these elements is achieved.

In particular, the pressing of the bushing in the spur element is seen as a very effective connection method, since in this way a permanent support of the bushing in the spur element can be achieved without additional steps or components are necessary.

In order to avoid a through bore of the spur element and in particular a screw through a blind hole can be provided.

A length of the spur, d. H. the pin including the spur member is typically between 2 and 8 cm, with typical lengths between 3.5 cm and 7.5 cm, in particular at about 4.5 cm.

An arrangement of the spur element on the pin is preferably carried out by a fixing element which between the pin and the Spur element acts such that the spur element is rotatable about the longitudinal axis of the spigot and substantially fixed in the direction of the longitudinal axis.

Such attachment of the spur element on the pin can be achieved for example by a locking ring which engages both in a circumferential outer groove of the pin and in a circumferential inner groove of the spur member.

As internal groove is understood in the present application, a circumferential groove which is arranged in the bore of the spur member. As an outer groove is understood a groove which is circumferentially introduced into the pin.

In an embodiment of the securing ring as a snap ring, it is dimensioned so that the snap ring engages in a relaxed state both in the circumferential outer groove of the pin and in the circumferential inner groove of the spur element. To produce the connection between the spur element and the journal, the retaining ring can be inserted, for example, by compression into the outer groove of the spur element and then pushed onto the journal under expansion of the snap ring. As soon as the snap ring reaches the region of the circumferential outer groove of the pin, it will elastically return to its original shape and engage in the outer groove of the pin. With a suitable dimensioning of the snap ring with an inner diameter which is smaller than an outer diameter of the pin in the region of the outer groove and having an outer diameter which is greater than an inner diameter of the blind bore of the spur member in the region of the inner groove is in this way a reliable fixation in the axial direction achieved while still ensuring a rotatability of the spur element.

Alternatively, the fixing element may be formed by a clamping ball. In an embodiment of the fixing element as a clamping ball, this can either be arranged on the pin and engage a correspondingly formed recess of the spur element or the spur element is designed as a clamping ball and engages over a bearing ball arranged on the pin. By both embodiments, a rotatability of the spur element is achieved about the longitudinal axis of the pin, which in particular can be saved by a configuration of plastic manufacturing costs.

In order to restore a full functionality of the spores invention then to ensure, if the unlikely event occurs that the camp blocked or lost the spur element, it makes sense if the pin is releasably attached to the support member. The pin can be releasably secured to the entire holding element or it is a first pin member formed as part of the holding element and a second pin member detachably connected thereto.

Furthermore, pins with different spur elements can be used by a detachable arrangement of the pin on the holding element.

A connection between the pin and the holding element is preferably made by means of a self-loosening connection mechanism. Such a connection mechanism may be formed, for example, as a click mechanism, as a self-locking thread, as a bayonet lock or as by means of a radially executed screw or a plug or locking pin.

An inhibited against self-loosening training of the locking mechanism is crucial, since an opening of the shutter mechanism and thus a release of the spur of the retaining element must be avoided. This is absolutely necessary, since otherwise injuries to the horse would have to be obtained and, on the other hand, an acceptance of the present embodiment would not exist with the rider.

In order to further refine the spore aid, the spur element may have a surface structure that supports a rolling process on the abdomen of the horse. Such a surface structure may be formed, for example, by an increased surface roughness of the material used for the spur element, by grooves, webs, depressions and / or nubs or nub-like elements.

As is also known from the prior art, the spores according to the invention can be offset inwards on the holding element in the use position, i. H. arranged offset in the direction of the horse and / or be angled.

FIG. 7

three embodiments of spurs according to the prior art (already treated).

FIG. 1 shows a first embodiment of a spur 1 according to the invention, in which a holding element 3 as a U-shaped bracket with which the spur 1 with the aid of, for example, leather straps on a riding boot can be fastened. The leather straps used for attachment are guided by the ends arranged on the U-shaped bracket 3 eyelets 32 and thus tightened the spur 1 on the riding boot.

In the in FIG. 1 shown embodiment, a substantially cylindrically shaped pin 5 is arranged on the U-shaped bracket 3 at its apex, which is designed in two parts in the present embodiment. The pin 5 is riveted to the U-shaped bracket 3, which has a bore 33 at its vertex and / or welded, so that a durable and material-mechanical connection between the pin 5 and the bracket 3 is made.

As already indicated, the pin 5 is made in two parts in the present embodiment, wherein a first pin element 51 is connected to the headband 3 and a second pin member 52 is releasably connected to the first pin member 51. In the present exemplary embodiment, the first pin element 51 has an internal thread 59 and the second pin element 52 has an external thread 57, so that the second pin element 52 can be screwed into the first pin element 51. The threads 57, 59 are formed inhibited against automatic untwisting, so that a release of the second pin member 52 is avoided by the first pin member 51 in a use of the spur A shown. In order to still allow a release of the connection of the two pin members 51, 52 are formed on the second pin member 52 has two opposite flats 53, which can serve as targets for a suitable tool, such as a commercial fork wrench.

On the pin 5 a spur element 7 is arranged end, which is formed in the present embodiment as a ball or substantially spherical. The ball 7 is mounted on the pin 5 such that it is rotatable about a longitudinal axis A of the pin 5. By such a bearing of the ball 7 on the pin 5 is achieved that the ball 7 in an application of the spur 1, d. H. upon application and slight up and down movement of the ball 7 to the horse in the region of the costal arch, in a rotation R about the longitudinal axis A is added, so that a snagging of the spur in the sensitive skin of the horse is avoided.

FIG. 2 shows a top view of the spur 1 from the FIG. 1 ,

In FIG. 2 is particularly clearly a rivet 11 between the pin 5 and the U-shaped bracket 3 can be seen. Around To prevent damage to the riding boot, the riveted joint can be arranged in a countersink and additionally welded and sanded. In FIG. 2 is also particularly clearly the longitudinal axis A of the pin 5 can be seen. With a double arrow also the possible rotation R of the ball 7 is indicated about this longitudinal axis A.

FIG. 3 shows a perspective view of the pin 5 from the Figures 1 and 2 in its individual parts.

The first pin member 51 has, as FIG. 3 can be removed, at its holding element side end a rivet bolt 61 which is inserted into the bore 33 of the bracket 3 and crimped from the opposite side and riveted to it. In this way, a particularly stable mechanical connection is made, which can be further enhanced, for example, by additional welding of the two elements 3, 51 and possibly optically embellished. At its opposite end, the first pin member 51 has an internal thread 59 which is formed corresponding to an external thread 57 provided on the second pin member 52. On the second pin member 52, a circumferential relief 58 is also provided at the end of the external thread 57, which ensures a defined completion of the thread. The threads 57, 59 are formed in the present embodiment, self-locking against automatic unscrewing, so that a release of the second pin member 52 is avoided by the first pin member 51. In a middle section, the second pin element 52 has the previously described flattenings 53 as starting points for a suitable tool for screwing and releasing the two pin elements 51, 52.

At its end remote from the first pin element 51, the second pin element 52 has a cylindrically shaped sliding surface 54 for interacting with the spur element or ball 7. Adjoining the sliding surface 54 is a circumferentially formed and chamfered web 55, on which a circumferential outer groove 56, which is formed between the web 55 and the middle section of the second pin element 52, follows. The circumferential outer groove 56 is formed such that in this as will be explained later, a suitably formed fixing element 91, which may be formed, for example, as a snap ring, engages, and the spur element or the ball 7 fixed in the axial direction on the pin 5.

FIG. 4 shows an embodiment of a spur element 7, as shown in the Figures 1 and 2 is used. The spur element 7 is formed substantially spherical and has a radially extending blind hole 70. In this blind hole 70, which is executed stepped in the present embodiment, a sliding bush 90 is pressed and introduced at an opening end, a circumferential outer groove 71. In the circumferential outer groove 71 is seated, as shown in Figure 4, a locking ring 91. The inlet opening of the blind hole 70 is also provided with a circumferential chamfer 72. In FIG. 5 is a longitudinal section along the longitudinal axis A of the pin 5 through the pin 5 and the spur element 7 according to the Figures 1 and 2 shown.

In FIG. 5 It can be seen particularly clearly how the spur element 7 designed as a ball is fixed on the journal 5 in the axial direction and is rotatably mounted about the longitudinal axis A. In the blind hole 70, the slide bush 90 is seated, on its inner circumference with the sliding surface 54 of the second pin member 52 interacts. A fixation of the ball 7 on the second pin member 52 is achieved in that the arranged in the circumferential inner groove 71 of the ball 7 circlip 91 is expanded at a sliding of the ball 7 on the second pin member 52 through the phase of the circumferential ridge 55 and behind this relaxed in the circumferential outer groove 56 of the second pin member 52 again. Characterized in that the securing ring 91 is dimensioned such that it has an inner diameter in the relaxed state, which is smaller than an outer diameter of the web 55 and has an outer diameter which is greater than an inner diameter of the blind hole 70 and the ball 7 in the relaxed state achieved a fixation in the axial direction.

FIG. 6 shows an alternative embodiment of a spur 1, in which on the pin 5, a bearing ball 6, which is designed as a spherical segment, is arranged. On the bearing ball 6 can be arranged via a clamping action designed as a clamping ball spur element 7, which is presently designed as a slotted spherical shell. By a plurality of distributed over the circumference of the spherical shell slots 73 an elasticity of the clamping ball is achieved here, via which they are pushed onto the bearing ball 6 and can lock elastically.

In this embodiment, both the pin 5 and the spur element 7 can be produced particularly inexpensively, since, for example, can be used on plastic as a material. Such an embodiment may be particularly suitable, for example, for beginnings of equestrian sports, since they can also be made particularly suitable for the horse by an appropriate choice of the radius of the spur element 7. A sliding bearing of the spur element 7 on the bearing ball 6 by suitable selection of the plastic used, so that they also in present embodiment is designed self-lubricating.

Alternatively to an embodiment as in Fig. 6 Shown in place of the spur element 7, the bearing ball 6, the slots 73 wear, so that they are elastically inserted into the spur element and can lock there.

Advantageously, the spur element 7 for the aforementioned embodiments, a correspondingly adapted inner contour, so that a secure support and the rotation of the spur element 7 is ensured on the pin 5.
