Definitions

  • the present invention relates to stirrups which are used to support the feet of riders of animals.
  • a tongue normally located beneath the foot of a rider is arranged to pivot upwardly and outwardly if a foot becomes jammed in the stirrup in order to push the foot out of the stirrup to avoid a rider being dragged along the ground.
  • the base of the stirrup upon which the foot of a rider normally bears is formed is defined by the upwardly facing surface of the tongue and a pair of members located closely adjacent to each side of the tongue.
  • the tongue and side members are formed from cast members and, whilst the surface of the side members may be chequered or serrated in order to afford some grip to a rider's foot, that grip may not be sufficient in all instances.
  • a stirrup including a first cast part having a first arm and a second cast part having a second arm, in which the two parts are pivotally connected together and are pivotally movable relative to each other between a first position, in which both of the arms are arranged, in use, to extend upwardly and a second position in which, in use, one of the arms is arranged to extend downwardly
  • the pivotal connection of the two parts is provided by at least one integrally cast projection on one of the parts extending into an opening in the other part.
  • the opening in the other part may be formed when that part is cast.
  • the pivotal connection of the two parts may be provided by a pair of cast projections extending into respective openings.
  • the cast projections may be provided on one of the parts with the openings being provided on the other part.
  • One of the parts may include two spaced portions which are capable of moving relative to each other away from an at-rest position and movement of the projection in a direction to disengage the projection from the opening may be opposed by movement of the two spaced portions away from their at-rest position.

  • the two spaced portions of the one part may be located either side of a portion of the other part.
  • the two parts may be connected together in the region of the base of one of the arms.
  • a method of pivotally connecting two parts of a stirrup to form a stirrup in which the parts are pivotally movable relative to each other between a first position, in which a separate arm of both parts, in use, extends upwardly and a second position in which, in use, one of the arms is arranged to extend downwardly, the method is characterised in that an integral projection on one of the parts is caused to extend into an opening in the other part.
  • a stirrup includes a foot support and, in use, upwardly extending portions from each end of the support, the stirrup being capable of being suspended from a location remote from the foot support, one of the upwardly extending portions being movable away from the other upwardly extending portion with that movement being opposed by a force exerted by a leaf spring with a free end of the leaf spring being arranged to be deflected, when the spring opposes movement of the one upwardly extending portion, away from the other upwardly extending portion is characterised in that the spring has a greater thickness in the direction in which the free end of the spring is arranged to be deflected at a region spaced from the free end than that thickness in the region of the free end.
  • the spring has a greater strength at the region where the bending moment is greater and yet has a reduced thickness where the deflection is arranged to occur.
  • the spring may increase in thickness in the region of the free end to a region spaced from the free end.
  • the spring may be tapered.
  • the spring may be integrally cast with one of the upwardly extending portions.

  • the sweeping portion may be arranged to abut the spring.
  • the combined depth of the - 5 - sweeping portion and the spring across the foot support may be substantially constant.
  • the sweeping portion may include a generally horizontal upwardly facing surface and the spring may include a generally horizontal downwardly facing surface.
  • the sweeping portion may have a greater thickness in the region of its end remote from the upwardly extending portion with which it is constrained to move than in its region adjacent to the other upwardly extending portion, and the sweeping portion may be tapered.
  • the sweeping portion may be integrally cast with the upwardly extending portion with which it is constrained to move.
  • a stirrup includes a foot support and, in use, upwardly extending portions from each end of the foot support, the stirrup being capable of being suspended from a location remote from the foot support, one of the upwardly extending portions being movable away from the other upwardly extending portion with a sweeping portion being arranged to move from the region of the foot support through the space normally occupied by a foot located on the foot support when one of the upwardly extending portions moves away from the other upwardly extending portion, and gripping means connected to the sweeping portion arranged to provide a grip to the foot of a user of the stirrup, the gripping means being arranged to move with the sweeping portion.
  • the gripping means may be detachably connected to the sweeping portion.
  • the gripping means may comprise a resilient member.
  • the gripping means may be arranged to co-operate with the side portion of the sweeping portion to connect the gripping means therewith.
  • the side portion, or both side portions of the sweeping portion may include at least one tapered or at least partially downwardly facing surface with which the gripping means are arranged to be connecte .
  • the gripping means may be arranged to extend to a lower level than the sweeping portion, and may be arranged to extend to a lower level than the sweeping portion at a pair of spaced locations.
  • the gripping means may be arranged to extend above the sweeping portion and to at least one, and preferably both sides of the sweeping portion.
  • One of the upwardly extending portions at the region of the base of that portion may be pivotally connected to the other upwardly extending portion by a portion which extends across the foot support.
  • the gripping means may be arranged to extend downwardly between the portion which extends across the foot support to pivotally connect one of the upwardly extending portions to the other upwardly extending portion and the sweeping portion.
  • the gripping means may be arranged to extend over that portion which extends from one of the upwardly extending portions to the other upwardly extending portion and pivotally connects those portions together.
  • the gripping means may comprise a resilient member or, alternatively or additionally, a nylon member.
  • the gripping means may provide a grip directly for the foot of a user or, alternatively, the gripping means may be arranged to have a grip member detachably connected thereto.
  • the grip member may be selected from one of a plurality of grip members having different gripping features.
  • the gripping means may be arranged to be connected to the sweeping portion when the sweeping portion is in a position in which one of the upwardly extending portions has been moved away from the other upwardly extending portion.
  • the sweeping portion may be arranged to extend immediately above a spring member which extends from one upwardly extending member to the other upwardly extending member.
  • the gripping means may be arranged to provide an inclined surface to the foot of a user.
  • the present invention includes any combination of the herein referred to features and limitations.
  • Figure 1 is a view from beneath a stirrup
  • Figure 2 is a cross-sectional side view through the stirrup shown in Figure 1 taken along the line II-II of that figure;
  • Figure 3 is a cross-sectional view through the tongue of the stirrup along the line III-III of Figure 1 with a grip member shown attached to the stirrup;
  • Figure 4 is a plan view of the grip member shown in Figure 3.
  • Figure 5 is a side view of a separate grip portion which may be attached to the grip member shown in Figure 4.
  • the stirrup shown in Figures 1 and 2 comprises two integrally cast members 10 and 12.
  • the member 10 includes an upwardly extending arm 14 which has an opening 16 at its upper end for the attachment to a strap of a saddle (not shown) .
  • the lower end of the arm 14 is formed with a pair of spaced side members 18 and a spring 20 located between but spaced from the side members 18.
  • the side members 18 and the spring 20 extend across the base of the stirrup.
  • the spring 20 is thicker in its side view nearer the base of the arm 18 than it is at its free end.
  • the cast member 12 includes an upwardly extending arm 22 with a sweeping member 24 extending across the base of the stirrup towards the base of the arm 14 and lying on the upwardly facing surface of the spring.
  • the sweeping member 24 is thicker in side view adjacent to the arm 24 than it is at its free end. Accordingly the greatest strength of the sweeping member is provided in the region where it will experience the greatest bending moment.
  • the member 12 is pivotally mounted on the member 14 by means of a pair of lugs 26 extending inwardly at the free end of each side member 18 being located in correspondingly shaped holes 27 in the member 12 at the base of the arm 22.
  • the lugs 26 are located in the holes in the member 12 by flexing the side members 18 away from each other with considerable force, locating the member 12 in position, and allowing the arms to flex back to the position shown when the lugs are located over the holes.
  • the member 18 may push against the members 12 when the parts are connected (as shown in Figure 1) .
  • the lugs 26 and the holes within which those lugs are to be located are each formed integrally with the members 10 and 12 during casting.
  • the spring acts to urge the point 28 upwardly and retains the arm with the sweeping member 24 extending upwardly and slightly outwardly.
  • the spring bias has greater strength at the location where the maximum bending moment is exerted and greater flexibility at its free end where the deflection of the spring occurs.
  • the downwardly facing surface of the sweeping portion is inclined upwardly from the arm 22 whilst the upwardly facing surface of the spring is inclined downwardly from the opposed arm 14.
  • Those inclined surfaces in the normal closed position, abut each other with the other surfaces of the spring and sweeping portion extending generally horizontally. Accordingly, the depth of the stirrup, in side view, is able to be constant and of a relatively shallow depth and yet the spring and sweeping portion have the optimum strength and (for the spring) flexibility with each being tapered. Indeed the stirrup is probably stronger and able to perform better than a stirrup in which the spring and sweeping portion are of constant depth between the arms.
  • the two castings of the members 10 and 12 are of EN56 steel which is a 13% ferretic steel.
  • a grip 30 is attached to the sweeping member 24.
  • the grip 30 extends over the sweeping member 24 and the side members 18 to provide an upwardly facing gripping surface 32 over the complete extent of the foot support of the stirrup.
  • the grip includes an opening 34 at either end, as shown in Figure 4, to accommodate the arms 14 and 22.
  • the grip 30 includes a pair of parallel spaced downwardly extending walls 36 which are located in the space between the side members 13 and sweeping member 24 and the spring 20.
  • the grip is retained in position by a pair of inwardly extending flanges 38 being located beneath downwardly and inwardly inclined surfaces 40 on the sides of the sweeping member 24. If the arm 22 is moved outwardly relative to the arm 14 the sweeping member 24 takes the grip with it, and also allows the grip to return to the position shown in Figure 3 with the sweeping member.
  • the walls 36 cooperate with the side members 18 or the spring or the sweeping member to prevent any significant movement of the grip relative to the stirrup through the stirrup. Furthermore, as the grip does not extend over the base of the stirrup in the fore or aft direction, no moment is able to be exerted on the grip which may tend to rock the grip off the stirrup.
  • the grip is attached to the stirrup by moving the arm 22 away from the arm 14 to the fully open position.
  • the flanges 38 are then located at the end of the sweeping member and the grip is slid down the sweeping member until it occupies the position shown.
  • the gripping surface 32 may have any desired configuration to assist in the grip afforded to a rider.
  • the surface may have pointed studs extending upwardly, as shown, or rounded studs or may have ridges.
  • a separate grip portion 42 such as shown in Figure 5 may be detachably secured to the grip by means of four mushroom studs 44 extending through corresponding holes 46 in the grip.
  • a plurality of grip portions 42 may be provided, each having a different upwardly facing surface or each being made of a different material, in order that a rider can select the required grip performance of the stirrup by selecting an appropriate grip portion.
  • the grip 30 may be made of nylon or any other relatively rigid material, particularly where a separate grip portion is to be secured thereto.
  • the upwardly facing surface of the grip may be arranged to be inclined to the horizontal when a stirrup is attached to a saddle, for instance by making the grip of greater depth at one end of the stirrup than at the other.
