Abstract
A safety stirrup detachably connected to the stirrup-leather in order to release the rider's foot in the event of a fall comprises a coupling device having two jaws for clamping the top portion of the stirrup head. A forward pivotal displacement of the stirrup with respect to the stirrup-leather causes rotation of a cam provided at the upper end of the stirrup head. The two jaws are opened-out by a top wedge of the cam through an angle of approximately 30.degree. to 45.degree. while a bottom wedge of the cam increases the separation of the jaws, thus releasing the stirrup.
Claims11
A safety stirrup for horse-riding comprising a stirrup head having an eye and being attached to a corresponding stirrup-leather by means of a coupling device comprising a retaining element engaged in the eye of said stirrup head and a resilient member for maintaining said stirrup head applid against said retaining element while permitting disengagement of said retaining element in the event of an abnormal pivotal motion between said stirrup and said stirrup-leather, wherein said safety stirrup is distinguished by the following features:
- (a) said coupling device comprises a resilient clamp having two jaws normally located in planes substantially parallel to the general plane of said stirrup, said two jaws being sized, shaped, and positioned to clamp the top portion of said stirrup head and being provided with bottom retaining noses engaged in the eye of said stirrup head and adjacently opposite one another;
- (b) the top portion of said stirrup head has the shape of a cam so designed as to be capable of caussing incipient separation of said two jaws in the event of rotation of said cam about its own axis up to an angle of the order of 30.degree. to 45.degree. approximately, the lower end of said cam being such as to form a wedge corner which is capable of engaging between the bottom retaining noses of said two jaws in order to increase their relative spacing and thus to permit excape of said stirrup;
- and
- (c) the cam which constitutes the top portion of said stirrup head has a flat bottom face which bears on the bottom retaining noses of said two jaws as well as two flat faces perpendicular to said bottom face and parallel to the general plane of said stirrup, said two jaws being normally applied against said two flat faces.
A safety stirrup for horse-riding comprising a stirrup head having an eye and being attached to a corresponding stirrup-leather by means of a coupling device comprising a retaining element engaged in the eye of said stirrup head and a resilient member for maintaining said stirrup head applied against said retaining element while permitting disengagement of said retaining element in the event of an abnormal pivotal motion between said stirrup and said stirrup-leather, wherein said safety stirrup is distinguished by the folliowing features:
- (a) said coupling device comprises a resilient clamp having two jaws normally located in planes substantially parallel to the general plane of said stirrup, said two jaws being sized, shaped, and positioned to clamp the top portion of said stirrup head and being provided with bottom retaining noses engaged in the eye of said stirrup head;
- (b) the top portion of said stirrup head has the shape of a cam so designed as to be capable of causing incipient separation of said two jaws in the event of rotation of said cam about its own axis up to an angle of the order of 30.degree. to 45.degree. approximately, the lower end of said cam being such as to form a wedge corner which is capable of engaging between the bottom retaining noses of said two jaws in order to increase their relative spacing and thus to permit escape of said stirrup;
- and
- (c) the top portion of said stirrup head is provided with a top rib of triangular cross-section in which the apex of the triangle is located uppermost so as to constitute a virtual separating wedge, the intended function of said top wedge being to permit ready repositioning of this portion of said stirrup head between said two jaws.
