Definitions

  • the present invention relates to a horse drawn sulky of the type used in sulky racing.
  • Racing sulkies vary in both the length and width thereof.
  • the driver By shortening the sulky, the driver is placed closer to the horse to result in improved aerodynamics of the combined horse and driver. This results in less drag and correspondingly greater speed.
  • the disadvantage of this structure is that the distance between the wheels has to be increased to prevent injury resulting from the horse kicking the sulky wheel while making a turn. Therefore, the horse must run further from the rail during turning and hence run a greater distance around each curve. This, of course, results in increasing the horse's time for completing a race. This problem may be avoided by lengthening the sulky. This results, however, in increasing the aerodynamic drag resulting from the combined horse and driver to result in decreased speed.
  • a horse's racing performance may be improved by adjusting the amount of weight transmitted from the horse to the sull y via the shafts of the sulky attached to the horse.
  • the more weight transmitted from the horse via the shafts to the sulky results in increasing the angle to a preferred 90° angle between the vertical axis of the horse's hoof and the track surface when negotiating a bend. This decreases the likelihood of injury to the horse during racing. If too little weight is transmitted from the horse via the shafts, however, during turning the horse will tend to lean further into the turn, which causes pain to the horse and decreases the speed of the horse.
  • a more particular object of the invention is to provide a sulky wherein the length of the sulky may be shortened without incurring increased jeopardy of the horse's hooves striking the sulky wheel during turns.
  • Another specific object of the invention is to provide a sulky wherein the amount of weight removed from the horse by the shafts of the sulky may be readily adjusted to provide an optimum amount of weight removed for any given combination of horse, driver and racing gait.
  • a horse drawn sulky that includes a pair of transversely separated wheels attached to and extending from a tubular frame and a pair of shafts attached to and extending forwardly from opposite sides of the frame and wheels.
  • the pair of tubular shafts are adapted for attachment to a horse generally centrally therebetween.
  • a driver's seat is attached to the frame rearwardly and centrally of the shafts.
  • Additional means are provided for selectively adjusting the pair of shafts that includes means for selectively attaching said pair of wheels to said frame and pair of shafts at a relatively more forward position to increase the weight transmitted from the horse to the shafts or at a relatively more rearward position to decrease the weight transmitted to the shafts from the horse.
  • the means for selectively attaching the pair of wheels to the frame and shafts may include a pair of front struts associated with each wheel and connected at one end thereof to an axle of each wheel on opposite sides thereof and at another end thereof to one of the shafts by a fastener.
  • the fastener is adapted for positioning longitudinally along the shaft to fasten the pair of struts to the shaft at a selected longitudinal position therealong. The position of the fastener is moved relatively forward to increase the weight transmitted to the shafts from the horse and relatively rearward to decrease the weight transmitted to the shafts from the horse.
  • Means are provided for attaching the pair of wheels to the frame that includes a transverse tube extending beneath and transversely across the frame.
  • the transverse tube has at each end thereof a pair of rear struts connected to an axle of each wheel on opposite sides thereof. Means are provided for connecting the transverse tube to the frame in releasable engagement to permit axial rotation of the transverse tube to move, as a unit.
  • each pair of rear struts moves forwardly upon relative forward movement of each of the pair of front struts and moves rearwardly upon relatively rearward movement of each of the pairs of front struts.
  • the driver's seat may be attached at a front end thereof to the transverse bar by seat attaching means.
  • Seat attaching means permit the seat to be pivoted forwardly about the transverse bar upon relative forward movement of the front struts and rearwardly upon relative rearward movement of the pair of the front struts.
  • the wheels may be transversely offset relative to the longitudinal center line of the pair of shafts.
  • FIG. 1 of the drawings is a side elevation of one embodiment of a sulky in accordance with the invention.
  • Fig. 2 is a plan view of the sulky of Fig. 1;
  • Fig. 3 is a front elevation of the sulky of Fig. 1;
  • Fig. 4 is a detailed view of a fastener embodied in the sulky; and Fig. 5 is a detailed view of one embodiment of a structure for pivotally mounting the seat of the sulky.
  • Fig. 6 is a detailed side view of a preferred embodiment of the structure for prvotably mounting the seat of the sulky.
  • the sulky has a pair of shafts 12 extending forwardly one on either side of the sulky.
  • the shafts are of tubular construction. At a forward end of the shaft is a portion thereof generally known as a point, which is designated as 14.
  • the opposite end of the shafts 12 are connected to a generally U-shaped tubular structure 16 commonly termed a "back bend” or "back bow.”
  • An undercarriage, designed generally as 18, extends generally transversely beneath the back bend 16.
  • the undercarriage 18 includes an upper transverse tube 20 and a lower transverse tube 22.
  • struts 24 are connected to wheels 26 on opposite sides thereof at a wheel hub 28 connected to opposite ends of axle 30.
  • a pair of front struts 32 is connected also to the hub 30 of each wheel at one end thereof, with an opposite end connected to shaft 12 by a fastener designated generally as 34 and shown in detail in Fig. 4.

  • a nut 48 is provided in threaded engagement with the bolt 44. Upon tightening of the nut 48 relative to the bolt 44, the end 46 of the front strut 32 is connected to the shaft 12.
  • the fastener 34 permits the longitudinal movement of struts 32 to move the wheels forwardly or rearwardly to respectively decrease or increase the weight imparted to the sulky by the horse.
  • the transverse tube 20 of the undercarriage 18 is connected to the back bend by a pair of identical U-shaped connectors 50 having threaded end portions (not shown) onto which cap nuts 52 are tightened in threaded engagement to secure the undercarriage to the back bend.

Pivot link 58 has an opening (not shown) through which rod 60 is inserted. In this embodiment, rod 60 is threaded, and it is secured to tab 58 by a threaded nut.

  • the drag is decreased to increase speed. This is achieved without increasing the width of the sulky as is necessary with symmetrically wheeled sulkies. likewise, with the use of offset wheels, the turning radius is decreased to increase the turning speed.

Abstract

Un sulky (10) tiré par un cheval comprend une paire de roues transversalement séparées (26), rattachées à un cadre tubulaire (16) et suspendues à ce cadre, ainsi qu'une paire de brancards tubulaires (12) rattachée au cadre et aux roues, et s'étendant vers l'avant à partir de leurs côtés opposés. La paire de brancard tubulaires (12) est conçue pour être rattachée à un cheval placé de manière généralement intermédiaire par rapport aux tiges. Un siège (54) de conducteur est fixé au cadre (16) en un endroit postérieur et intermédiaire par rapport aux brancards (12). Une paire d'élément de fixaton réglables (34) est prévue pour régler les brancards (12) vers le bas et dans la direction du cheval afin d'augmenter le poids transmis à partir du cheval vers les brancards (12), et vers le haut à partir du cheval afin de réduire le poids transmis du cheval aux brancards (12), le sulky s'adaptant au mouvement grâce à un montage pivotant des étais postérieurs (24) transversalement reliés, par l'intermédiaire de dispositifs d'accouplementen U (50) montant ces étais sur le cadre tubulaire en U (16). La paire de roues (26) peut être transversalement décalée par rapport à la ligne centrale longitudinale passant entre la paire de brancards (1), alors que le siège (54) peut être relié pivotant à la partie transversale d'étais postérieures (54), ce qui permet un ajustement correspondant par rapport au mouvement des brancards (12) vers le haut ou vers le bas.
