The invention relates to sporting goods, specifically, to horse riding equipment.
Horse riding stirrups, also referred to as stirrup irons, are suspended from each side of a riding saddle to provide a rest for rider's feet. A portion of rider's weight is continuously supported by the small area of contact between rider's feet and the stirrups. Horse riding and, especially, horse jumping may require a rider to maintain a so-called two-point position with the rider's full weight and substantial dynamic loads concentrated in those few square inches of contact. This area is further reduced when rider's foot rocks and presses against the edge of the stirrup platform. A ride may extend for an hour or more and many professional and active amateur riders may ride several horses a day.
This concentrated pressure can have severe impact on person's feet, including impeded circulation leading to reduced foot sensitivity and mobility, as well as foot and ankle pain during and following riding activity. This negative experience detracts from the enjoyment of recreational riding and from performance in competitions. Permanent issues may develop over time, including arthritis, that may affect the person's wellbeing outside of the riding arena. These issues are not adequately addressed by riding boots as such boots are typically designed with thin and flexible soles for closer contact and greater sensitivity.
Additionally, maintaining proper position of feet in the stirrups is a commonly experienced challenge for horse riders. A rider's foot may slip out of or deeper into the stirrup, interrupting the normal flow of riding and contributing to the risk of a riding accident. The physical and mental effort of keeping hold of the stirrups is a distraction from the more relevant aspects of riding activity.
The present invention describes an ergonomic stirrup design that seeks to address the above issues by providing a larger area over which the load is distributed and maintaining said area over a range of foot positions and movements.
In this disclosure, “length” refers to a measurement along a rider's foot and “width” refers to measurement across a rider's foot. “Front”, “back”, “inside”, and “outside” are defined with respect to the direction of a rider's foot. When rider's feet are referenced, it should be understood in the context of a horse riding activity, including the use of customary footwear.
One aspect of an ergonomic horse riding stirrup invention is a longer footrest compared to a typical English stirrup footrest. A second aspect of the invention is a footrest with a concave shape to cradle the ball of the foot. A desired shape can be created, for example, by front and back platform surfaces forming an angle or by a smooth front-to-back curvature.
This shape can further be created or enhanced by deformation of an elastic layer covering the top of the stirrup footrest, a third aspect of the invention. The elastic layer can be pre-shaped, or it may possess sufficient thickness and elasticity to mold to the sole of a rider's boot under normal load. The elastic layer also provides additional shock absorption during riding activities.
A fourth aspect of the invention is a stirrup pad with a top surface having a shape and properties described above. The pad can be permanently attached to a stirrup frame, or it can be a removable pad to be used with stirrup frames designed for interchangeable pads. A set of several such pads may provide a range of characteristics optimized, for example, for competition, horse training, and pleasure riding.
A fifth aspect of the invention is a stirrup footrest with an opening that cradles the ball of a rider's foot. The opening may optionally hold an elastic pad or be filled with elastic material.
A sixth aspect of the invention is a stirrup footrest with a dynamically adjustable shape. For example, the stirrup footrest may form a hinge with its axis affixed to the two opposite ends of the stirrup arch. The shape of the footrest can be adjusted by closing or opening the hinge to accommodate the shape of the rider's sole or personal preference.
In addition to distributing rider's weight and dynamic load over a wider area, a shaped stirrup footrest described above helps maintain a fixed position of rider's foot with respect to the stirrup. An extended contact area further counteracts slippage with increased friction. The invention thus reduces the probability of a rider's foot sliding forward into the stirrup and getting caught in the stirrup in the event of an accident. The ability to maintain a secure and confident stance in the stirrups will allow a rider to fully concentrate on better control of a horse and thus further improve safety of a riding activity.
The following embodiments are discussed as non-limiting cases. Other embodiments of the invention should be apparent to those skilled in the art.
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.
In one embodiment, as illustrated in
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 (
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
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 (
In one embodiment, the footrest comprises two substantially flat platforms 203a and 203b, joined at an adjustable angle (
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 (
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
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.
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.
The present application is based on U.S. provisional application No. 62/385,921, filed on Sep. 9, 2016, the contents of which are hereby incorporated by reference.
