An independent claim is also included for a method for fabricating a spur.

Description

The technical sector of the present invention is that of spurs for riders. There are two categories of spurs: straight spurs and curved spurs. The right spurs are installed on the heel of a boot or shoe of the rider so that the wheel or the shaft equipping the spur is in the extension of the heel. The curved spurs have a more complex shape for the purpose of locating the wheel or shaft higher, that is to say substantially to the right of the rider's ankle, or lower than the heel of the shoe or in a axis different from that of the heel of the shoe. These two categories of spurs are usually held on the rider's boot by means of a strap that passes over the rider's kick. The object of the invention is of the category of curved spurs. The utility model DE29913729U1 discloses a spur of this category which has a first U-shaped portion and a second portion which has several sectors angularly inclined relative to each other, a last sector being placed in a hollow located between the sole of the boot and its heel. The entire spur is made from a flat strip of material.

However, this spur suffers from major drawbacks. One of the main disadvantages lies in the difficulty of making such a spur. Indeed, the use of a flat strip complicates or prohibits the angles of curvature operated in the flat plane of the strip. It is therefore necessary to use heavy technical means such as the use of press to cut in a wider band angularly inclined sectors. Another disadvantage of the state of the art cited above lies in a bad positioning of the spur on the boot of the rider. Indeed, the positioning of the spur is dictated by the size of the boot and in the case of small boot, the wheel or the rod rises higher on the ankle of the rider thus causing a rotation of the sectors of the spur placed between the sole and the heel. As this sector is flat, this rotation causes an inclination and a bad support on the heel of the rider's boot. It is therefore understood that such a spur is not adaptable to several sizes of boots. Finally, another disadvantage of this type of spur profile is that it tends to become easily fouled because the flat strip retains the earth and in general all the foreign bodies that a rider can cross. The object of the present invention is therefore to overcome the disadvantages described above mainly by providing a spur capable of being easily formed and made adaptable so that a single spur size is usable for several sizes of boots or shoes. In addition, the spur according to the invention considerably limits the retention of impurities during its use.

The invention therefore relates to a spur including a rounded area extended at each of its ends by a branch, each branch is extended by a sector inclined relative to an extension direction of the adjacent branch, each sector is extended by a retaining segment inclined with respect to an extension direction of the adjacent sector, that is to say contiguous, characterized in that the rounded area, the branches, the sectors and the retaining segments have a circular section. The branches can extend in the same plane as the rounded area.

The spur is formed of a unitary wire, that is to say uninterrupted from one end to the other of the spur. According to a first characteristic of the invention, the circular section is between 12.56 mm 2 and 28.26 mm 2.

According to a second characteristic of the invention, the section is substantially identical over the entire length of the spur, which ensures the possibility of threading a rod and / or a sheath and / or a strap attachment. According to another characteristic of the invention, a rod is fixed perpendicularly to the rounded zone, said rod has a recess of complementary shape to the circular section of the spur. According to yet another characteristic of the invention, the recess is a first circular hole whose section is greater than the circular section of the spur. According to another characteristic of the invention, the first hole extends along an axis perpendicular to a longitudinal axis of the rod, said axis being placed between two and three millimeters from one end of said rod.

The stem also includes a second hole whose axis is parallel to a longitudinal axis of the rod, said second hole opening into the first hole. Alternatively, the recess is a notch made at one end of the rod, said notch having a complementary shape bottom to the circular section of the spur. In the spur of the invention, the sector is inclined relative to its adjacent branch at an angle of one hundred and fifteen degrees plus or minus ten percent. Advantageously, the retaining segment is inclined relative to its adjacent sector at an angle of 100 degrees plus or minus ten percent. Advantageously, the retaining segment has an arc whose convexity is turned towards the rounded area. Thus, the distance between the point of inflection of the arc and a straight line passing through both ends of the retaining segment is equal to the diameter of the wire increased from three millimeters to plus or minus ten percent. According to another characteristic of the invention, the retaining segment comprises at its free end a ball. Advantageously, at least one of the branches or at least one of the sectors comprises a locking means of a strap for attaching the spur. The invention also relates to a method of manufacturing a spur, characterized by the following steps: - a section of circular section is cut to a predetermined length, the wire is rounded in the middle of the determined length to form a rounded area and two branches, each of the branches being bent at an angle of one hundred and fifteen degrees plus or minus ten percent to form an inclined sector, each sector is bent at an angle of one hundred degrees plus or minus ten percent to form a segment of Retention 30, round each retaining segment to form an arc that turns its concavity to the rounded area. Prior to the step of forming the rounded area, a rod is passed which extends perpendicularly to the wire and then welded rod on the wire. A first advantage of the invention lies in the ease of manufacture of such a spur where the circular section of the latter can be bent easily whatever the direction chosen. Another significant advantage lies in the fact that the circular section allows constant support behind the heel of the rider's boot, regardless of its position on the ankle. Another advantage of the invention lies in the fact that the circular section makes it easy to thread a rod to be welded on the spur.

Other characteristics, details and advantages of the invention will emerge more clearly on reading the description given below for information in connection with drawings in which: - Figure 1 is a top view of a spur according to FIG. 2 is a side view of a spur according to the invention, FIG. 3 is a sectional view of the spur according to the invention illustrating the circular section of the spur, FIG. FIG. 4 is a perspective view of the rod equipping the spur according to the invention; FIG. 5 is a perspective view of the spur according to the invention equipped with its attachment straps; FIG. a view of a sheath before mounting on the spur of the invention; FIG. 7 is a perspective view of the spur including an improvement.

The figures serve to describe in detail the object of the invention but can also serve to better define the invention, if any. Figure 1 illustrates a spur 1 according to the invention made from a wire of circular section. This wire is more particularly a 304 or 316 INOX or a nickel-plated steel. The diameter of the wire constituting the spur is between four and six millimeters, which leads to a circular section of between 12.56 mm 2 and 28.26 mm 2. The wire that forms the spur is unitary, that is to say formed from the same length of wire. The spur 1 comprises a rounded area 2 which fits in a circle of radius between 22mm and 25mm, advantageously 24mm. The rounded zone 2 has two ends illustrated in this figure by two broken lines. Each of these ends is extended by a branch 3, 4 which extends in a direction of extension parallel and identical to the plane in which extends the rounded area 2. This extension direction and this plan will be better illustrated on the FIG. 2. Each of the branches 3 and 4 continues with a sector 5 and 6, the latter extending in a direction of extension referenced A and B which is inclined with respect to the direction of extension of the branches 3 and 4. It will be noted at this stage of the description that the branches 3 and 4 as well as the sectors 5 and 6 can be perfectly rectilinear or have a slight curvature. In the case of rectilinear branches / sectors, the angles are more marked whereas in the case of a slight curvature, the angles connecting the rounded zone 2 to the branches 3, 4 and the angles connecting the sectors 5, 6 to the branches 3, 4 are softer, which is more appreciable from an aesthetic point of view. In either case, it is important that the sectors 5 and 6 extend in a plane that is perpendicular to a tangent that passes through the point of inflection of the rounded zone 2. Each of the sectors 5 and 6 is extended by a retaining segment 7 and 8 in a direction of extension referenced C and D which forms an acute angle obtus al and az of one hundred degrees plus or minus ten percent relative to the extension directions respectively A and B. Each of retaining segments 7 and 8 has a free end capped with a ball or cap 9 and 10. These balls 9 and 10 have the function of avoiding hanging the heel of the boot during assembly of the spur, which results in ease of installation on the boot by the rider. In practice, these balls 9 and 10 can be made by deformation of the wire at the free ends of the retaining segments 7 and 8, by supplying soldered or welded material or by means of a plastic cap or wood nested force or even glued on the free end of each retaining segment 7 and 8. Figure 1 also illustrates the presence of an arc 11 formed on the retaining segment 7 and another arc 12 formed on the retaining segment 8. Each arches 11 and 12 are formed such that their convexity is turned towards or towards the rounded area 2. It is thus understood that the point of inflection of this arc bears against the heel of the boot so as to facilitate the mounting the spur while ensuring a significant holding effort on the heel. The distance between the point of inflection of the arc and a fictitious line passing through the two ends of the retaining segment 7 or 8 is equal to the diameter of the wire increased from three millimeters to plus or minus ten percent. Note also the presence of a rod 13 placed at the rounded zone 2. This rod 13 extends in a direction substantially perpendicular to the tangent which passes through the point of inflection of the rounded area 2. The detail and the mode of attachment of this rod will be better detailed in Figure 4. Figure 2 illustrates the plane E in which extends the rounded area 2 and the extension direction F in which the branches 3 and 4 extend. Note that this direction of extension F and this plane E are parallel, that is to say that there is no angular fold between the rounded area 2 and the branches 3 and 4.

The sectors 5 and 6 extend respectively in the extension directions A and B, the latter forming an obtuse angle 51, respectively 52, of one hundred and fifteen degrees plus or minus ten percent. Figure 3 shows the circular nature of the wire section used for the invention. The wire may be solid, as shown in this figure, but it may also be hollow at its center so as to form a tube. Even if the section shown here is a section SS of Figure 1 to the right of the branch 3, the circular section is identical over the entire length of the spur, that is to say from the retaining segment 7 in passing through sector 5, then branch 3, rounded zone 2, then through branch 4, sector 6 and finally ending with segment 8. This circular nature of the section of the spur 1 offers the advantage of easily forming a spur of the curved type but also facilitates assembly with the rod 13, the latter being fitted or threaded on the wire constituting the spur 1. Figure 4 is a detailed view of the rod 13 which equips the spur 1 according to the invention. This rod 13 extends along a longitudinal axis referenced G and is in the form of a solid tube of circular section with a diameter of between 6 mm and 10 mm. This rod 13 has a free end 14 which is used by the rider to bear on the sides of the equine and thus solicit. This free end 14 may be provided with a styling tip made of rubber, plastic or leather. The shape of this tip is advantageously cylindrical or conical. The other end of the rod, referenced 15, comprises a recess 16 which takes the form of a first through hole through the rod 13 along an axis perpendicular to the longitudinal axis G. The diameter of the first hole is greater to the diameter of the wire of the spur 1 so as to thread this wire in the first hole and thus come place the rod 13 at the rounded area 2 of the spur 1. The distance between the axis of the first hole and the 15 end of the rod 13 is between two and three millimeters so that the rod 13 does not protrude from the rounded area 2 to the inside of the spur 1. In a first variant, the rod 13 is secured to the rounded area 2 by welding or brazing around the first hole or by a spot welding technique pointing through the rod 13 to the right of the first hole. In a second variant, the end 15 of the rod 13 comprises a second hole 17 formed along an axis parallel to the longitudinal axis G, substantially in the center of the rod 13. This second hole 17 opens into the first hole and is used to secure the rod 13 on the rounded area 2. Indeed, the second hole 17 is used as a welding well on the spur wire, which allows to limit or avoid a finishing operation by polishing.

In another variant not shown, the end 15 of the rod is cut in a direction parallel to the longitudinal axis G so as to form the recess in the form of a notch having a complementary shaped bottom to the circular section of the spur 1. Such a solution has the advantage of mounting the rod 13 on the spur 1 after shaping of the latter and in a direction parallel to the longitudinal axis G, welding or brazing occurring within the the spur to the right of the rounded area 2, that is to say in an inconspicuous area of the rider. This avoids having to put the rod 13 on the thread of the spur, which ensures its connection with the rounded area 2 at a suitable time of the manufacturing process. Similarly, the cutting of the end 15 may occur along an axis perpendicular to the longitudinal axis G thereby forming the recess and mount the rod 13 in a direction perpendicular to the longitudinal axis G. The recess will then be placed on the lower part of the rounded area 2 and filled by welding or brazing, this placement making it less visible. FIG. 5 shows the spur 1 equipped with a rod 13 and with straps or fastening straps 18 and 19. The latter each comprise at least one loop 20, 21 threaded on the sector 5, 6 or on the branch 3, 4 or at the junction between a branch and a sector. To prevent the loops 20 or 21 from sliding on the circular section of the spur, the invention proposes to provide the sector 5, 6 or the branch 3, 4 concerned with a locking means of said strap 18 or 19. A first example locking means has been shown at the junction of the branch 4 and the sector 6 in Figure 5. This locking means consists of two soldering points 22 and 23 spaced apart from each other by a distance at least equal to the width of the loop 21. Another example of locking means is also represented at the junction of the branch 3 and the sector 5 in the form of a first section of tube 24 and a second section of tube 25 both threaded on the wire of the spur and solder or solder thereon. Here too, the distance between the first section 24 and the second section 25 is at least equal to the width of the loop 20.

To improve the aesthetics and avoid damaging the boots of the riders, the spur according to the invention is completed by sheaths threaded on the constituent wire of the spur, each sheath covering in one piece each torque sector 5 / branch 3 and sector 6 / branch 4. Note also that this sheath can extend to the rounded area 2 so as to end near the rod 13, and thus hide the welds of the rod on the rounded area . FIG. 6 shows, on the side, such a sheath referenced 26. This sheath consists of a leather band whose two longitudinal edges 27 and 28 are joined or joined to one another by a connection, for example a seam 29 At least one of the longitudinal edges has a locking means of a strap attachment of the spur.

In the specific example of Figure 6, the locking means is formed by a notch 30 formed in at least one of the longitudinal edges of the strip. This notch 30 can be performed after sewing 29 as is the case in Figure 6 but it can also be implemented by an interruption of the seam thus forming said notch. Figure 6 shows the sheath 26 in a situation before mounting on the spur 1. In this case, the width of the notch 30 is greater than the width of the loop of the strap attachment. When the sheath 26 is threaded on the spur, the notch 30 is placed at the junction of the branch 3 and the sector 5 and oriented so that the notch is placed in the concavity of the fold between the branch and the sector concerned. This results in a narrowing of the width of the notch and its side walls then come to tighten and lock the strap hooking of the stirrup. The problem of fastening the fastening strap connected to the circular section of the thread constituting the spur 1 is thus cleverly solved. As an alternative to a leather sheath, it is advantageous to provide a sheath made of rubber or flexible plastic, possibly thermosetting. In this case, the spur consists of four strips of plastic sheath or rubber, a sheath being threaded on each branch to extend over the rounded area. Then, we put the loop of the hanging strap on the spur. Finally, another sheath is threaded on each sector of the spur so as to block the buckle of the strap, the space remaining between two adjacent sheaths corresponding to the width of the loop. The use of a thermosetting plastic is advantageous because the sheaths can be easily threaded and then heated and retracted to a specific place. FIG. 7 shows a spur 1 in perspective equipped with a strap 18, 19 and a rod 13 covered with a plastic tip referenced 31. The particularity of the spur according to FIG. 7 rests in the locking means of FIGS. strips 18 and / or 19. As the wire is of circular section, the loop 20 or 21 of the strap concerned can slide and possibly fall from the spur. To avoid this defect, the spur is equipped with a locking means of a strap (18, 19). This locking means here takes the form of a wire 32, preferably of circular section. This wire 32, of a smaller diameter than the wire constituting the spur, doubles the latter by being installed on the lower part of the spur. The wire 32 comprises a circular zone 33 curved along a radius equivalent to the circle in which the rounded zone 2 (22 to 25mm) is inscribed. Substantially in the middle of the branches 3 or 4, a connection point 34 is made, for example by brazing or welding, between the wire of the spur and the wire 32 of the locking means. The circular zone 33 extends on each side beyond the point of connection 34 by an arm 35, the latter extending in a direction inclined with respect to the plane in which the circular zone 33 is inscribed. The angle between these two elements is between 15 ° and 40 °. The arm 35 is terminated by a finger 36 which is constituted by the free end of the wire 32 which has been bent at an angle of approximately 90 ° to the wire of the spur 1. The finger 36 bears on the thread of the spur which defines a stop that limits the movement of the loop 20 or 21 of the strap 18 or 19. This strap remains on the spur without risk that it slips. The edge of the finger 36 or wire 32 in contact with the wire of the spur is not welded to the latter so as to thread the loop 20 by acting by memory deformation on the arm 35. It will be noted that there is a distance between the end of the finger 36 and the connecting point 34 greater than the width of the loop 20 which offers the ability to move or translate slightly the strap 18 or 19 and thus better place the strap on the boot of the rider. Finally, it will be noted that the material used for the spur wire and the wire 32 of the locking means is identical. The invention also covers a method of manufacturing a spur 1. The steps of such a method are as follows. a wire of circular section is cut to a predetermined length, the wire is rounded in the middle of the length determined to form a rounded zone 2 and two branches 3 and 4, advantageously substantially symmetrical, each of the branches 3 is folded, 4 at an angle of one hundred and fifteen degrees plus or minus ten percent to form an inclined sector 5, 6, 20 - each sector 5 and 6 is folded at an angle of one hundred degrees plus or minus ten percent to form a retaining segment 7 and 8, - each retaining segment 7, 8 is rounded to form an arc 11, 12 which turns its concavity towards the rounded zone 2. Prior to the step of forming the rounded zone 2, a rod 13 having a recess 16 which is in the form of a first hole, so as to place the rod 13 perpendicular to the wire. Alternatively, the rod 13 has a recess 16 in the form of a notch thus making it possible to return the rod 13 after conformation of the spur 1.

The method also includes a step in which the rod 13 is welded to the wire of the spur 1. The method also comprises a step where a ball is formed at the free ends of the retaining segments 7 and 8, provided by of material, by force-fitting a cap or by gluing such a cap. Prior to the ball-forming step at the free ends of the retaining segments, a pre-formed sheath 26, which has a notch 30, is placed on each pair of branches / sectors, the latter being placed at the junction of the branch and the sector. adjacent.
