DETAILED DESCRIPTION OF EMBODIMENTS
(8) Stirrup in its Configuration for Normal Use
(9)
(10) By convention, in the present application, the “forward direction” is the direction of advancement of the horse during the normal use of the stirrup, “the rear direction” is the opposite direction, “the inward direction” is the direction directed towards the horse during the normal use of the stirrup, and the “outward direction” is the reverse direction. Moreover, the term “end” in this application refers to the portion of a component of the stirrup that is in the region of its extreme limit.
(11) Stirrup 1 comprises a flattened horizontal branch forming a platform 11, which is intended to receive the sole of a rider's footwear. Platform 11 is advantageously covered on its upper face by a non-slip coating 110 forming tread 11. The latter is connected at its first end, or inner end 111, to a first side branch or inner side branch 13, and at its second end, or outer end portion 112, to a second side branch or outer side branch 2. The inner side branch 13 and the outer side branch 2 rise from the tread to an upper portion 12 of the stirrup where the upper extremities of the two side branches meet. An opening, called the eye 120, allows the passage of the stirrup leather (not shown), which is a leather strap attached to the saddle and carrying the stirrup.
(12) The inner side branch 13 is intended, in use, to be placed at the side facing the horse of the foot of the rider. This inner side branch 13 is a fixed branch which rigidly connects the tread 11 to the upper portion 12 of the stirrup.
(13) The outer side branch 2 is intended, in use, to be placed at the side directed away from the horse of the rider's foot. This outer side branch 2 is, according to the invention, a movable branch. In the configuration for use of stirrup 1, shown in
(14) Advantageously, stirrup 1 can be made of aluminum. However, in this case, upper portion 12, inner side branch 13 and tread 11 are preferably reinforced by steel rods, giving them the necessary strength.
(15) Stirrup in its Open Configuration
(16)
(17) Thus, when the foot of the rider exerts a sufficiently high pressure from inside the loop formed by the stirrup on the outer side branch 2, outer side branch 2 can pivot away from inner branch 13 as shown in
(18) Holding the Stirrup in the Position for Use
(19) The swivel linkage which gives many degrees of freedom to outer side branch 2, makes it somewhat difficult to maintain outer side branch 2 in its position for use shown in
(20) To meet these conflicting requirements related to the implementation of the swivel linkage, stirrup 1 includes a positioning device for the lower end 22 of outer side branch 2 relative to the outer end portion 112 of tread 11 of the stirrup, the positioning device making use of magnetic attraction in order to render reversibly integral outer side branch 2 and the outer end portion of tread 11. The positioning device includes a first magnet 1121 integrated into the outer end portion 112 of tread 11 and adapted to cooperate with a second magnet 221 integrated into the lower end 22 of outer side branch 2.
(21) More specifically, the outer end portion 112 of tread 11 has a first contact surface 1120, particularly visible in
(22) A first magnet 1121 is inserted and fixed in a housing provided for this purpose in a first contact surface 1120, and a second magnet 221 is inserted and fixed in a housing provided for this purpose in second contact surface 220. These two magnets advantageously have complementary polarities, to attract each other and to become centered relative to each other, in a position corresponding to the configuration of use of stirrup 1. The magnets 221 and 1121 thus ensure outer side branch 2 is held in its position for use and can also ensure return of outer side branch 2 to its position for use when the second side branch slightly shifts, whatever the direction of this shifting. Furthermore, the strength of these magnets 221 and 1121 is advantageously chosen to allow separation between outer side branch 2 and outer end portion 112 of tread 11, when pressure is exerted on outer side branch 2, whether this pressure is exerted in an outward direction, a forward direction or a rearward direction.
(23) Embodiment of a Swivel Linkage
(24) A swivel linkage between the upper end portion 21 of outer side branch 2 and upper portion 12 of stirrup 1 can be achieved by any means known to those skilled in the art. A particular embodiment implemented in stirrup 1 is described below, particularly in connection with
(25) The upper portion 12 of the stirrup has a surface 121 intended to be in contact with a matching surface 211 of an upper end 21 of outer side branch 2, in the position for use of this outer side branch 2. Surface 121 has a cylindrical blind hole 1210 formed in upper portion 12 of the stirrup. This hole 1210 is intended to receive a first end of an elastic cord 51 which can be locked in hole 1210 by tightening a screw 122 passing into hole 1210.
(26) The surface 211 of upper end portion 21 of outer side branch 2 also has a cylindrical hole 2110 into which the second end of the elastic cord can be introduced. This hole 2110 opens into a compartment 23 provided in the body of outer side branch 2. The second end of the elastic cord, opening into this compartment 23 can be locked in position there, for example by means of a knot, after the elastic cord has been stretched to the desired tension. A cover 230 is then placed over compartment 23 to close and hide it. The elastic cord thus acts to bring the surfaces 121 and 211 closer while allowing them to move away under the effect of a force stretching the cord in order to allow angular movements of outer side branch 2.
(27) Preferably, surface 211 has a centering stud 2111, through which hole 2110 passes, and surface 121 carries a recess 1211 in which a hole 1210 is drilled and which has a shape matching that of centering stud 2111. Stud 2111 and recess 1211 make it possible to ensure good positioning of the upper end portion 21 of outer side branch 2 with respect to upper portion 12, in the configuration of use of stirrup 1. In particular, stud 2111 and recess 1211 have non-circular cross-sections, here triangular, which force outer side branch 2 to a specific angular position, when in its position for use. It should be noted that stud 2111 and recess 1211 have dimensions and shapes such that they do not interfere with the rotational movements of outer side branch 2 relative to upper portion 12 of the stirrup when the outer side branch is moving to its open position leading to an elongation of the elastic cord.
