Definitions
- the present invention relates to horse-drawn cars, used for training or in harnessed trot competition, and called "sulkies"
- the design of these two-wheeled tracks is developed from a main frame, made of metal profile (s) on which are fixed, generally by bolting, elements and equipment such as stringers (p), adjustment bars (q) and toe clips (f), wheels (r), struts (e) and sometimes, especially on so-called “long” sulkies, one or more hangers (n) connecting the stringers
- This main beam comprises, on the other hand, by welded and / or brazed elements - at its center, and in a weak rear overhang, a profile (î) generally curved in the form of a console, to support the seat (h ) the client;
- the main frame of the car consisting of welded and / or brazed elements, therefore not adjustable, requires, first of all, its manufacturer to decimate it into several sizes, depending on the size of the horse to which it is assigned, - in the event of a weld or brazing fracture during use, the rigidity of such a metallic structure is capable of injuring more or less seriously, before bending, the biological crew of the coupling or of 'another, in the event of a collision.
- - fig 2 schematizes the longitudinal mechanical balance adopted by the majority of conventional sulkies, such as that of fig 1, - fig 3 also schematizes the longitudinal mechanical balance but, this time, according to the inventive concept,
- FIG. 4 illustrates an elastic embodiment example of elements constituting the framework of a sulky according to the invention, with a variant in FIG. 4b,
- FIG. 5 illustrates another example of an elastic embodiment of a frame of lean sulky the intrinsic ⁇ gidity of the arms making it up
- FIG. 6 shows in perspective view an example of the possibility of adjustment between the constituent elements of a sulky frame according to the invention
- FIGS. 7a, 7b and 7c illustrate, in higher elevations, three half-views relative to the longitudinal axis of adjustment and / or arrangement possibilities between elements and components of a sulky according to the invention
- the weight of the divider F2, applied to the hanger h in slight overhang at the rear in Cl, is counterbalanced by the weight FI of the stretcher R-C2 in cantilever before, if the sulky is correctly adjusted
- the couple in Cl being annihilated by the couple in C2
- the bridge, between C2 and C3 undergoes only a slight alternating twist, due to the i ⁇ egula ⁇ té of the dynamics (this slight twist is moreover b ⁇ dée by the strut (e) in fig 1)
- an obstacle such as a track on the track for example, the whole of the sulky swivels neatly around the point R, anchoring the stretcher on the harness of the equid and equilibrium point, otherwise unstable Only the bending of the bridge momentarily increases with the passage of the obstacle
- the balance between front and rear overhangs is reduced only at the height of the hub M, because the fork C2-M works here mainly in bending-traction, while the seat stem Cl -h works almost exclusively in bending Indeed, the wheel and its fork, as well as the seat h are here in strong cantilever rear
- the bridge, axis of torque reduction is transferred in front of the vertical axis of the running gear, the torque reduction centers C2 and C3 are swapped compared to the previous diagram (fig 2)
- the stem and forks of the sulky are made of materials with a high margin of elastic deformation and, therefore, their assembly points, although possibly removable, are rigidly secured to each other
- Either the stem and forks are made of materials with low margin of elastic deformation in bending, and the stresses are transferred in torsion around the longitudinal axis of the otherwise ⁇ gide bridging, and an elastic connection is interposed in the form of a ring based on 'elastomer at the junction points between elements
- the stem ( ⁇ ') seat, and a fork arm (k ') both having no intrinsic flexibility, are therefore individually connected to the rigid bridge (j) by means of elastic joints (s) working essentially in torsion by means of a viscoelastic material, this in order to increase the angular clearance between torque Cl and against torque C2 explained with reference to fig 3, to absorb the jolts due to the dynamics of the coupling
- all the main elements constituting the framework of the sulky are independent of each other. of the others and are mechanically fixed to each other either by bolting and / or screwing, or by keying, bundling etc, the important thing being that each element is solidly fixed to another, while remaining easily removable, and not definitively solidary as by soldering, welding or gluing.
- this removability makes it possible to dimension sequentially the distances between constituent elements of the framework of the sulky, using anchors fixing points as shown in fig 6 by the nominal and directional plurality of fixing points
- the element B for example, here fixed in bl on gl and in b3 on al, can be offset and be fixed in b4, always on al and in b2 always on gl, or vice versa
- the element D by its position, could here be moved in the same plane by the fixing points a '1, a'2 etc, and / or in a plan orthogonal according to dl, d2, d4
- this fork can be arranged "astride" relative to the stringer on this same bridging (fig 7b) or even closer to the axis by passing on the inside side of the silt (fig 7c), also modifying either the spacing between silts, or the very way of the sulky or still sound.
- transverse dimensions provided that, in the case of a hanger (n) like that of fig. 1, this is replaced by a separate strap with stringer, thus squaring it with respect to the bridging as shown in the diagram from fig 7
