Ergonomic Horse Riding Stirrup

Abstract

A horse rider's weight is at least partially supported by pair of stirrups suspended from the sides of a riding saddle. This weight is concentrated at the points of contact between the rider's feet and the stirrups, contributing over time to discomfort, fatigue, and injury. Ergonomic riding stirrups distribute rider's weight over a wider contact area, while promoting a natural foot shape and position. This effect is conveyed by a stirrup footrest shape that is complementary to a natural foot shape during a riding activity.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The following embodiments are discussed as non-limiting cases. Other embodiments of the invention should be apparent to those skilled in the art.

[0021] In one embodiment, an ergonomic stirrup 100 comprises an arch 101 and footrest 102 supported by the arch. The footrest length may be between 2 inches and 5 inches, or about 3 inches, or about 1.5 times the length of an average English riding stirrup footrest.

[0022] In one embodiment, as illustrated in FIG. 1, the footrest comprises two substantially flat platforms 103a and 103b, joined at an angle. The angle may be, for example, between 135 degrees and 175 degrees. The two platforms may have substantially the same length, or they may have different lengths. For example, the front platform may be longer than the back platform. A junction between the two platforms may comprise one of a corner (FIG. 2A), a flat area (FIG. 2B), a rounded area, and an opening.

[0023] In another embodiment, a top surface of a footrest has a curved shape 104, wherein a low point of the curved shape is near a middle of the footrest (FIGS. 2C, 2D). In one embodiment, the top surface of a footrest is curved in the front-to-back direction and the curved shape approximates a segment of a circle or another conic section. The top surface of a footrest may be further curved in the inside-to-outside direction and the curvature in the front-to-back direction may be larger than the curvature in the inside-to-outside direction. In one embodiment, the top surface of a footrest is curved to approximate the shape of a rider's foot in a riding position, with the low point of the curve corresponding to the ball of the foot.

[0024] In another embodiment, a top surface of a footrest comprises an elastic material that deforms under the weight of a rider to approximate the shape of the rider's foot in a riding position. The elastic layer may deform under rider's weight, for example, by between 0.1 of an inch and 1 inch, or by about 0.5 of an inch. In one embodiment, as illustrated in FIGS. 3A-C, the elastic material is arranged in a deformable layer 120 that overlays a solid footrest base 110. At least one of the thickness and the elasticity of the deformable layer is selected to achieve a desired degree of deformation of the layer. The top surface of the elastic layer may be flat (FIGS. 3A, 3B), or it may be curved (FIG. 3C) as described in reference to other embodiments above. The elastic layer may possess elastic memory to at least temporarily retain its shape once deformed. The solid base may further be flat (FIG. 3A), or it may be curved (FIGS. 3B, 3C) as described in reference to other embodiments above. A curved solid base may help achieve a desired shape using a thinner deformable layer. The deformable layer may be permanently attached to the solid base, or it may be attached as a removable and replaceable pad.

[0025] In a related embodiment, a solid footrest base 110 comprises an opening 105 and an elastic material is arranged in a deformable layer 120 that overlays the opening. The opening may be a blind (FIGS. 4A-C) or a through opening (FIGS. 4D, 4E). The elastic material may further at least partially fill the opening (FIGS. 4B-E). This design has several desirable features. Without a solid backing, a desired degree of deformation may be achieved with a firmer and, consequently, more durable elastic material. The deformable layer can be made thinner and the overall height of the footrest can also be reduced. The elastic material may be furnished as a removable pad and the footrest may incorporate means of securing said pad, such as flanges or set screws.

[0026] In one embodiment, the footrest comprises two substantially flat platforms 203a and 203b, joined at an adjustable angle (FIGS. 5A-C). The angle may be adjustable, for example, between 135 degrees and 180 degrees. In this embodiment, a junction between the two platforms may comprise a hinge mechanism 230. A junction between the frame arch 201 and the footrest may further comprise at least one hinge mechanism. An at least one hinge mechanism in this embodiment may include a locking mechanism to lock the angle between the platforms in between adjustments. An adjustment screw may be incorporated into the design to control the angle.

[0027] A related embodiment may incorporate a spring-loaded mechanism 240 acting to maintain a flat footrest when no weight is applied and changing its angle dynamically in response to foot position and load. Hard stops may be incorporated into the stirrup arch to limit angle variation to a predetermined range. An elastic layer 220 may be incorporated into this embodiment (FIG. 5C).

[0028] In yet another embodiment, a solid footrest comprises an opening that allows the sole of a rider's boot to deform into a shape approximating the shape of the rider's foot in a riding position. Such a footrest 302, as illustrated in FIG. 6A, comprises a front support bar 303a, a back support bar 303b, and an opening 305 in between, which is wide enough to allow for such a deformation. The opening 305 cradles the ball of the foot, partially relieving the pressure that would otherwise be concentrated in this area. At least one of the front and back support bars may be angled down toward the center of the stirrup. FIGS. 6A-C further shows how a stirrup arch 301 and a footrest 302 may be furnished as separate pieces for final assembly into a stirrup 300. The opening in the footrest may be filled with elastic material.

[0029] The invention illustrated in the above embodiments may be combined with other features designed to enhance rider's performance, safety, and comfort. Such features may include, for example, surface materials, textures and patterns designed to promote friction between the top surface of a footrest and a rider's foot. Other enhancements may include various safety features, such as automatic release mechanisms and breakaway designs for the outer arm of a stirrup arch.

[0030] A stirrup may be fabricated, without limitation, of a metal or an alloy, such as stainless steel, aluminum, titanium; a plastic, a metal reinforced plastic, a composite material, such as fiberglass, carbon fiber reinforced polymer; or another material or combination of materials known to those skilled in the art. A stirrup pad may be fabricated, without limitation, of a variety of elastomer materials.
