DETAILED DESCRIPTION

[0050] Identical or equivalent elements in the figures have the same reference signs.

[0051] A safety stirrup for horse-riding according to a first possible embodiment is described below with reference to FIGS. 1 to 7a-7d. The safety stirrup for horse riding essentially comprises three parts, specifically a buckle 1, a stirrup 2 and a clip mechanism 3 interposed between the buckle 1 and the stirrup 2.

[0052] This clip mechanism 3 forms, with other parts positioned firstly on the lower end of the buckle 1 and secondly on the upper portion of the stirrup 2, a device for attaching the stirrup 2 to the buckle 1 that is designed to permit unclipping or complete detachment of the stirrup 2 from the buckle 1 in the event of a rider fall, as explained below.

[0053] The stirrup 2 has an overall arch shape in which a rider can insert a foot in an insertion direction that is substantially perpendicular to the plane containing the arch. The insertion direction of the foot is shown by the arrow F, in particular in FIGS. 1 and 2. The stirrup 2 conventionally includes a tread 20 in the lower portion onto which a rider can place his foot, and two lateral branches 21, 22 linking the tread 20 to a head 23 stirrup 2. The stirrup 2 may also have a single lateral branch between the tread 20 and the head 23. As shown in some of the figures, the tread 20 may advantageously include projections or any other means designed to enhance adherence and potentially to provide shock absorption.

[0054] The buckle 1 has an opening 10 on the upper end of same through which a stirrup leather (not shown) may be attached.

[0055] As specified previously, the attachment device is formed by elements carried firstly on the buckle 1 and secondly on the stirrup, as well as on the clip mechanism 3 interposed between the two.

[0056] More specifically, the buckle 1 has two lateral extensions 11 and 12 on the lower end of same (particularly visible in FIGS. 1, 3, 4) that are designed to cooperate with two flanges 24, 25 fitted to the head 23 of the stirrup 2. As shown in particular in FIGS. 3 and 4, the two flanges 24, 25 extend opposite one another and parallel to the plane containing the arch, said flanges forming a passage 26 intended to receive the lower end of the buckle 1. More specifically, the lower surfaces 27 of the two flanges 24, 25 (only one of which is visible in FIG. 6) form two shoulders against which the upper surfaces of the two lateral extensions 11 and 12 bear respectively (see in particular FIGS. 3 and 6).

[0057] The mechanism 3 for clipping the stirrup 2 to the buckle 1 extends between the two flanges 24 and 25. The clip mechanism includes at least one elastic element, in this case a spring 30 extending along the longitudinal axis of the stirrup 2, having a free end that is received, in a clipped position, in a corresponding notch 13 formed in a lower surface of the lower end of the buckle 1, linking the two lateral extensions 11, 12 (see in particular FIGS. 7a, 7c and 7d). The notch 13 has an end stop 14 that is designed to cooperate with the free end of the elastic element 30 to prevent the stirrup 2 from unclipping from the buckle 1. Conversely, the elastic element 30 may under certain circumstances move past the end stop 14 to enable unclipping. A roller 31 or any other element designed to facilitate sliding between the free end of the elastic element 30 and the end stop 14 is preferably provided in the clip mechanism 3.

[0058] In the embodiment shown, the elastic element 30 is seated primarily in a central recess 28 provided in the head 23 of the stirrup 2, beneath the passage 26 formed by the two flanges 24, 25 (see FIG. 4). To facilitate the preservation and assembly of the parts, the elastic element 30 is advantageously seated inside a substantially parallelepipedic cartridge 32 (FIGS. 1 and 6), which may be inserted into the central recess 28 of matching shape.

[0059] The cartridge 32 advantageously has two lugs 33 (FIGS. 1 and 6) that are used to retain the roller 31 to prevent same from touching the bottom of the corresponding notch 13 when in the clipped position, and also to prevent same from being ejected following unclipping. FIGS. 4 and 6 in particular show how the roller 31 is held in the cartridge 32 of the clip mechanism 3.

[0060] In normal use, the stirrup 2 is clicked to the buckle 1 by the action of the spring 30, which is compressed and pushes the roller 31 into the notch 13 of the buckle.

[0061] Furthermore and according to an important feature of the invention, the lower surfaces 27 of the two flanges 24, 25 provided in the head 23 of the stirrup on one hand, and the upper surfaces 11a, 12a of the two lateral extensions 11, 12 provided on the lower end of the buckle 1 on the other hand have a curved profile and together form sliding surfaces to enable a relative rotation of the stirrup 2 and of the buckle 1 in said insertion direction of a foot of the rider into the stirrup.

[0062] Furthermore, in this embodiment and as shown particularly in FIGS. 7a to 7d, the notch 13 is wide in that same extends parallel to the curved profile over a given length to enable the relative rotation of the stirrup 2 and of the buckle 1 in said insertion direction of a foot of the rider into the stirrup before the elastic element 30 moves past the end stop 14 to enable unclipping.

[0063] The sliding surfaces 11a, 12a and 27 combined with a wide notch provide the stirrup 2 with angular freedom in relation to the buckle 1 before the elastic element 30 moves past the end stop 14 to enable unclipping. After unclipping, the portions of the sliding surfaces 11a, 12a and 27 that are still in contact enable a relative rotation that is sufficient to result in complete detachment if the situation requires (in the event of a fall).

[0064] FIGS. 7a to 7d more specifically show a sequence of the relative positions of the buckle 1 and of the stirrup 2 occurring in the event of a rider falling towards the rear of the horse. In these figures, the safety stirrup for horse-riding is shown as a cross-section taken in a plane perpendicular to the plane of the stirrup, and reference sign P is used to identify a foot of the rider inserted in the stirrup in the insertion direction shown by the arrow F.

[0065] At the beginning of the fall (FIG. 7a), the foot P is caught at the top of the stirrup. A shape 29 (also shown in FIG. 1) is preferably provided at the top of the stirrup to stop the front of the shoe. This shape 29 prevents the foot from hindering the release of the buckle in the event of a fall.

[0066] Torque is then generated, turning the stirrup 2 in relation to the buckle 1 as a result of the curved shape or profile of the sliding surfaces The stirrup 2 nonetheless remains clipped to the buckle 1 until the roller 31 reaches the end stop 14 (FIG. 7b).

[0067] As the rider continues falling backwards, the torque is sufficiently high for the end stop 14 to compress the spring 30 and force the roller 31 to enter the seat of the cartridge (FIG. 7c). After unclipping, the stirrup can be completely detached from the buckle 1.

[0068] In the embodiment described above, it is clear that angular freedom is essentially provided before the stirrup 2 is unclipped from the buckle 1. Thus, under normal conditions nonetheless involving jumps, the stirrup can still move in relation to the buckle without unclipping (and therefore without complete detachment). Unclipping and then detachment only occur in the event of a fall.

[0069] The notch 13, as shown in FIGS. 7a to 7d, has a fixed depth. As a variant, as shown in FIG. 8, the notch 13 may have a variable depth, and more specifically said depth may lessen as the roller 31 approaches the end stop 14. This solution advantageously enables the stirrup to be centred while enabling resisting angular freedom. When the constraint is removed, the stirrup 2 automatically centres itself.

[0070] In another variant embodiment shown in FIG. 9, a two-indent notch with an appropriately placed intermediate stop may be provided. This provides two successive notches, the dimensions of which can be varied advantageously. For example, a first portion of the notch, before the intermediate stop 15, may have substantially the same diameter as the roller 31, and a second portion of the notch, between the intermediate stop 15 and the end stop 14, may be shallower. In this case, after a first unclipping (moving past the intermediate stop 14), the roller 31 is in the second, shallower portion of the notch, which enables restricted angular freedom (the spring 30 is slightly compressed and the stirrup 2 turns less freely). This solution enables the stirrup to be centred while enabling some angular freedom in the event of a bad landing not involving a fall.

[0071] In another variant embodiment shown in FIG. 10, the length of the notch 13 is adjusted to the size of the free end, in this case the roller 31, of the elastic element 30. In this case, since the roller 31 is already stopped in the clipped position, the spring 30 is immediately compressed by the slightest relative rotational movement between the buckle and the stirrup, in particular in the event of a fall, and the stirrup 2 is unclipped from the buckle 1. However, the stirrup 2 and the buckle 1 have not yet been detached, and are still connected to one another by the portions of the sliding surfaces that are still in contact. This unclipped position without complete detachment is shown in FIG. 10.

[0072] The attachment device also advantageously includes a front stop 16 between the buckle 1 and the head 23 of the stirrup, in this example carried by the buckle 1. The front stop 16 is intended to prevent the stirrup from turning forwards (in the event of a bad jump, bad landing, etc.).

[0073] Other embodiments of a safety stirrup for horse-riding according to the principles of the invention are described below with reference to FIGS. 11 to 16. In particular, only the notable differences from the stirrup described above are given.

[0074] Thus, FIG. 11 shows that the clip mechanism with the spring 30 thereof is not necessarily beneath the passage 26 created by the two opposing flanges 24 and 25, but may be offset horizontally. The lateral extensions 11, 12 and the seats formed by the flanges to receive these extensions are thus asymmetrical, unlike as shown in FIG. 3.

[0075] It is also not necessary for the curved sliding surfaces to be defined by the contact surfaces between two lateral extensions cooperating with two flanges. FIG. 12 thus shows how a single flange 25 may be provided in the head 23 of the stirrup, to cooperate with a lateral extension 11 on the buckle.

[0076] The flange/lateral extension coupling may also be inverted. Thus, FIG. 13 shows how two flanges 11′ and 12′ can be provided on the lower end of the buckle 1, and how the lateral extensions 24′ and 25′ can be provided on the head 23 of the stirrup. Unlike the example shown in FIG. 3, in this case the upper surfaces of the two flanges 11′, 12′ form two shoulders against which the lower surfaces of the two lateral extensions 24′ and 25′ bear respectively.

[0077] In the embodiments described so far, the elastic element 30 of the clip mechanism is seated primarily in a recess 28 provided in the head 23 of the stirrup. However, entirely equivalently and as shown in FIG. 14, the position of the parts of the clip mechanism may be inverted by seating the elastic element 30 of the clip mechanism primarily in a recess provided in the buckle 1. The corresponding surface with at least one relief (for example the notch and the end stop of same described above) is then carried by the head of the stirrup.

[0078] The elastic element 30 may also be an elastomer such as the one shown in FIG. 15. The elastic element may be a ball. In this case, the relief cooperating with the elastic element may be a slot or simply a hole.

[0079] A particularly interesting embodiment is shown in FIG. 16. In this embodiment, a part 4 designed to be attached removably beneath the lower end of the buckle 1 is provided. A lower surface of this part 4 includes the notch into which the end of the spring 30 is seated, instead of a lower surface of the lower end of the buckle 1 directly. The part 4 can therefore be changed easily in the event of premature wear. Another advantage is that a given rider can choose a part 4 with a different notch, thereby adjusting the angular freedom provided. If the elastic element 30 is primarily seated in the buckle, the removable part can then be attached to the head of the stirrup, and includes the corresponding notch on the upper surface of same.
