1. Field of the Invention
The present invention is a portable and retractable stirrup especially useful for equestrian riding. The retractable stirrup is an additional stirrup temporarily attached to the saddle of a riding animal, such as a horse. It allows a rider a method to assume the correct riding position on a horse when the normal riding stirrup is too high for the rider to conveniently place his foot into the stirrup. The retractable stirrup provides a type of stair movement that greatly assists a rider with limited leg movement such as the elderly, with a smaller size such as children, or when the horse is at a higher elevation than the rider. The stirrup has been particularly designed to require a very small storage space, as storage on a riding saddle is normally very limited.
2. Discussion of Related Art
U.S. Pat. No. 6,688,088 describes a horse mounting aid method that includes a second smaller stirrup that is mounted just below the horse mounting stirrup. This additional stirrup has practical problems in actual use. The stirrup may be drawn up under the fender and/or side jockey when not used. This places the equipment in contact with the horse causing chafing and injury. It is difficult and dangerous for the rider to actually remove the temporary stirrup without falling to the ground because the rider must lean over to remove it. Finally, there is no provision to securely lock the temporary stirrup to the stirrup leather.
U.S. Pat. No. 5,661,957 describes an extendible stirrup for a horse. One of the saddle riding stirrups is mounted on a spring loaded mechanism. Since the mechanism is designed to serve two purposes, which allow a rider to easily mount onto the horse, and also provide for a secured riding position, the retraction mechanism is overly complicated with a long list of many moving parts (col. 11, 12).
U.S. Pat. No. 5,347,797 describes a temporary mounting stirrup for a horse. The temporary mounting stirrup is looped around the saddle horn and provides a lower stirrup for the rider to lift upwardly to a higher elevation with the right foot. The storage of the temporary mounting stirrup is poorly designed, by looping the strap and securing the loop with a D ring and clip. The temporary stirrup remains hanging from the saddle, and creates a hazard of catching on objects, such as brush or tree limbs. It may be removed by lifting the strap over the horn, but the strap does not loop conveniently into a compact storage. It is difficult for a rider to place a foot into the strap when the rider has limited leg movement. The strap does not have a defined opening for the foot, which is inconvenient for the rider and, when used, causes painful side pressure on the foot. The strap is not secured to the saddle horn and there is the likelihood of the strap falling off when riding hard. There is no provision for placing the strap immediately behind the normal riding stirrup. A person with poor leg motion will find it hard to cross the legs in the cramped space between stirrups to get the correct leg into the normal riding stirrup.
U.S. Pat. No. 4,761,938 describes a stirrup extension that hooks onto the existing riding stirrup, but there is no safe and convenient method for the rider to remove the extension without leaning over severely to reach the top of the device. It has limited use as it is dangerous to leave the extension on the riding stirrup as it may catch on tree limbs and bush, and further, it is liable to fall off.
U.S. Pat. No. 4,601,161 describes a leg up strap that is designed to assist the rider in climbing onto a horse. The strap has limited use as there is no provision for the rider to remove the strap from the horse when mounted. It is hazardous to leave the strap in place while riding, and the flexible foot opening creates unwanted side pressure on the foot as already mentioned in previous discussions on other patents.
This invention pertains to a conveniently removable mounting stirrup that may be designed for various lengths, allows the rider the ability to climb into a riding saddle with limited leg movement, and provides for convenient, very compact storage. The mounting position and mechanism facilitates an easy and secure method of attachment, and also a convenient way for the rider to store the stirrup and to re-attach it while on top of the riding animal.
One important goal of this invention is to provide a method to allow a rider with limited leg movement to more easily mount up on an equestrian saddle. It also provides suitable assistance for riders with shorter legs, such as children.
Another important goal of this invention is to provide a method where the temporary mounting stirrup is conveniently removed and stored by a rider in a bag, such as a saddle bag. The device has been particularly designed with consideration to this by using flexible material, to the extent practical, so it may be stored in a very compact space. It also has been designed so that the flexible material will conveniently wind around a winding buckle, such as used in seat belts. The stirrup has been designed to be light weight and present little hazard under normal use.
The upper strap 12a and lower strap 12b are preferably the same type of strap to ensure that the winding buckle 13 will function properly; however, this is not a requirement. The winding buckle 13 may also be designed to wind up the upper strap 12a, the lower strap 12b, or both straps. The continuous stirrup strap 14, the upper strap 12a, and lower strap 12b may be the same or different types of material. Any suitable strap material may be used that will carry the required load safely, and have appropriate wear properties. In a preferred embodiment, a strap material that is suitable for a seat belt is used for all three straps.
An important embodiment of the current invention is to allow the length of the retractable stirrup to be varied. This may be done by increasing the length of the upper strap 12a and lower strap 12b. A buckle or adjustable belt can also be added to either strap to vary the length. As an alternative, similar devices that provide for strap length adjustment may be applied that are well known in the art.
The stirrup tread 15 is preferably of suitable dimensions for functionality and for compact storage. Experiments with different stirrup tread 15 designs found that a rectangular bar with an opening for the continuous stirrup strap 14 with the outside dimensions of 5½ inches long, 1½ inches wide, and ¾ inches tall was suitable. Preferred lengths were found to be 4½ to 6″ long, based on typical foot widths. A ¾″ wide stirrup tread 15 was found to be too small and allowed the foot to easily slip out. Suitable widths were found to be 1 to 1½″ wide. A preferred stirrup tread 15 material is an aluminum rectangular structural tube that is 5½″ long, 1″ wide, and ½″ tall with a ⅛″ metal thickness. As a preferred embodiment, the top of the stirrup tread 15 may be modified to prevent foot slippage by adding a slip resistant material or increasing surface roughness as is well known in the art.
The actual use of the retractable stirrup is straight forward. The retractable stirrup is attached to the saddle, the rider pulls the stirrup tread downward until the upper and lower straps are completely extended from the winding buckle, and then the rider puts the right foot into the retractable stirrup. The rider then puts the left food into the normal riding stirrup, swings the right leg over the saddle, and sits. The spring winding mechanism in the winding buckle then retracts the straps automatically, and the rider may then remove the retractable stirrup and store it. Alternatively, the rider may allow the retractable stirrup to remain in place.
In particular, this invention has been conceived to allow for a very compact storage. The unit can be collapsed to fit into a rectangular box 6″ inches long, 2″ deep, and 2.5″ tall which equates to 30 cubic inches. It would also fit into a cylindrically shaped storage bag 6″ long with an equal volume. This allows the unit to be conveniently stored by the rider in a saddle bag, knapsack, or other storage place accessible to the rider. The use of flexible straps makes this possible, rather than using many rigid members to define the stirrup assembly.
While various embodiments of the present invention have been described, the invention may be modified and adapted to various uses to those skilled in the art. Therefore, this invention is not limited to the description and figures shown herein, and includes all such changes and modifications that are encompassed by the scope of the claims.
