GIRTH FOR SADDLES

Description

PURPOSE OF THE INVENTION

[0001] This invention refers to a girth for saddles, which is based on two independent pieces, which can be fitted together, one that comes into contact with the horse and another with the elements necessary for buckling the girth to the corresponding saddle. See e.g. EP 2 361 876 A1.

[0002] The purpose of the invention is to achieve a girth that responds to the locomotion and breathing movements of the horse, safe in its function and multi-purpose in order to be able to adapt it to different measurements and different disciplines.

BACKGROUND OF THE INVENTION

[0003] As it is known, the conventional girths used to set a saddle used in riding and in all its disciplines, are formed by a single body, making the disassembly impossible and therefore allowing the independent cleaning of each of the parts.

[0004] Another drawback that conventional girths present is that they are usually rigid, and therefore do not adapt to the horse's breathing and movements.

[0005] However, one girth is known with several innovations comparing the conventional girths, with the following particularities:

• It is a girth in which the complete disassembly of the pieces is intended to be established and it is not symmetrical in its overall configuration.
• In addition, the union between the part that buckles to the saddle and the part in contact with the horse is done with Velcro®-type elements.
• It also presents the drawback that in case of the breaking of the elastic elements that participate in the girth, although this is be improbable, it would lead to a risk of falling for the rider, with the additional particularity of the elastic elements being a cord wound two or three times and connected to the centre with a clamp.

• The change of measurement for this girth is complicated for the inexpert user.
• The expansion of the horse's ribcage during inhalation is not directed since it does not have trapezoidal rings.

DESCRIPTION OF THE INVENTION

[0006] The recommended girth has been conceived to solve the problem expressed above, based on some improvements that provide considerable advantages over the girths existing on the market.

[0007] More specifically, the invented girth is described in the appended claims. In one embodiment it is composed of two pieces, one in contact with the horse and the other for buckling to the corresponding saddle, and presents the particularity of both pieces being practically identical, although the piece to be buckled to the saddle is shorter, since it is supported on the piece in contact with the horse, with both being symmetrical, with respect to their longitudinal axis as well as their transverse axis, with the particularity that the piece in contact with the horse presenting a central leather keeper and two pairs of lateral leather keepers, the first for the passing of a fastening strip to the piece that buckles to the saddle, and the second ones for the passing of the adjustment belts and buckle holders. Another novel characteristic is that the two pieces present two pairs of cuts, one straight and another arched, in order to aid the expansion and adaptation to the horse's ribcage, since the girth does not expand equally in the front and in the back, taking into account that the ribcage of the horses (as with the majority of the vertebrates) is closed in the front (or upper part in the bipeds) and open in the back (or lower part in bipeds). Both front and back cuts have been rounded on the ends in order to enhance the design without substantially breaking the symmetry described above.

[0008] In turn, the piece used for buckling to the saddle, being, as mentioned above, of the same configuration although of lesser length, presents as a difference the fact that all the pieces, except the adjustable belts and buckles, are fixed inseparably and strategically with respect to such piece, which allows better breathing, adaptation, safety and comfort of the horse, as well as directing this force towards the buckles that fasten the girth to the saddle.

[0009] This buckling piece, in addition to some ventilation holes and the cuts to favour the adaptation to the horse's ribcage, presents a small notch in the front part and logically in the centre, which serves for placing a D-ring for the corresponding martingale, so that this notch fulfils two functions; on the one hand it allows identifying which is the front position of the girth, and on the other hand, the place to set the D-ring, through a strip sewn to the piece.

[0010] Another novel characteristic is that the strip that buckles the D-ring mentioned above, is a belt that extends towards the opposite edge, and through a screw establishes the fastening of this piece to the piece in contact with the horse, so that this fastening together of both pieces is done coinciding the cuts, as well as the ventilation holes, with the particularity that this strip is the one that passes through the central leather keeper on the piece in contact with the horse. The aforementioned fastening screw allows the separation of both pieces for their independent cleaning, since because of the material in which they are made, they will require different maintenance. This fastening is reinforced by Velcro® which avoids the waving or arching of the upper leather piece, which through its use and the passing of time can have this tendency, with the possibility of placing a rigid element in the lower part of the leather and between the trapezoidal rings that will be described later.

[0011] Another novel characteristic is that on the commented piece that buckles to the saddle four pairs of rings have been provided with a right trapezoid shape, two interior pairs and two exterior, so that the two interior pairs are fixed and are sewn, using the corresponding strips, to the piece itself, while the two exterior pairs are related to the previous ones and provided on the ends of elastic straps, to which in turn are attached the corresponding adjustment belts to which the buckles are linked, with the special particularity being that the double-pass buckles have a safety screw, all of this in such a way so as to adapt the strap to different measurements, so that it is easy to tighten the screw in order to set the measurement securely.

[0012] Furthermore, and returning to the rings, they shall have a right trapezoidal shape and are placed inversely, the interior ones with respect to the exterior ones, with the special particularity that the elastic straps that join the interior right trapezoidal rings with the exterior right trapezoidal rings are complemented by some nylon strips that, on the one hand, establish a means to limit the maximum extension of these elastic straps, and, on the other hand, comprise a safety element in case of breakage.

[0013] In this way, a girth is achieved that presents the following advantages with respect to those referred to in the "Background of the Invention" section:

• Minimum number of separable pieces, since in this girth there are only the two principal pieces, one in contact with the horse and the other for buckling, with only the adjusting straps with the buckles being separable, while the rest of the elements are fixed to the piece considered as the buckling element.
• By means of the invented girth, the expansion that the horse makes in breathing and locomotion is redirected longitudinally towards the buckles that fasten the saddle.
• The pieces are symmetrical, that is, the one that is in contact with the horse and the one that is the carrier of the fastening elements, which favours their manufacturing and adaptation.
• The fact should be highlighted that the union of the piece that comes in contact with the horse with the piece provided with the buckling elements is done safely by means of leather keepers and they are also reinforced with Velcro®.
• Similarly and due to the fact that the nylon strips are located inside of the elastic straps that join the interior trapezoidal rings to the exterior rings, it is achieved that in case of breakage of any elastic strap, something that is quite improbable, there is no risk of the rider falling, since the girth will remain joined by means of these nylon strips that are found located inside of the elastic straps.
• The fact should also be stressed that the separation between the trapezoidal rings and the elastic straps are a result of tracing a perpendicular line with the trapezoids (with 70° orientation), until reaching the same longitudinal plane as the buckles that fasten to the saddle, and therefore, the elastic straps from the start of their expansion, redirecting outwards the force or stress of the horse's inhaling, allowing the ribcage to expand freely according to the horse's needs.
• Furthermore, the fact should be underscored that the elastic straps that participate in the invented girth are flat, allowing a better redirection of the force exercised by the horse through the right trapezoidal rings, contrary to what occurs in any other girth.
• The fact should also be highlighted that the materials used in the protector that is in contact with the horse are breathable, allowing better evaporation of the horse's perspiration towards the exterior through it, considering that by being able to separate this piece as many times as you want, it provides a level of cleaning and hygiene difficult to achieve with any other girths. In addition, the wool parts of the girth can be disassembled and remain separate from the leather and other materials, for their independent washing, either by hand or by machine.
• Finally, it should be stated that due to the strategic placement of the fixed parts of the buckling piece to the saddle, the breathing, adaptation, safety and comfort of the horse is favoured, obtaining its better performance and improving its inhalation capacity as well as the freedom of movement in any of the equestrian gaits, since the girth adapts completely to the changing contour of the horse, without offering resistance, thanks to the strategic cuts made in the pieces, and in the elastic straps that join the trapezoid rings.

PREFERRED REALIZATION OF THE INVENTION

[0015] As can be seen in the abovementioned figures, the invented girth consists of two pieces (1) and (2), of equal configuration, although piece (2) is shorter than piece (1), with the latter being the one that is used to come into contact with the horse, while piece (2) is the one used to carry the elements used for buckling and adjustment of the girth with respect to the saddle.

[0016] Piece (1) presents a central and main leather keeper (3) for the passing of a strip, which will be explained later, which constitutes a means of connection between this piece (1) in contact with the horse and piece (2) for fastening to the saddle. Both pieces (1) and (2) are reinforced with strips of Velcro® to provide greater rigidity to the area that rest on the horse's sternum.

[0017] Furthermore, this piece (1) includes some end or lateral leather keepers (4) for the passing of the adjusting belts of the girth, as will be explained later.

[0018] Both piece (1) and piece (2) are symmetrical with respect to their longitudinal axis and with respect to their transverse axis, and in both cases there are holes (5) that make the perspiration possible and therefore the ventilation through the piece that will be placed in contact with the horse.

[0019] Both pieces (1, 2) have a pair of straight cuts (6) and a pair of arched cuts (7), being oblique in both cases and made in such a way as to coincide in both pieces when they are fastened together.

[0020] Piece (2) presents a notch (8) for a D-ring (9) that is held by a strip (10) which is the one that passes through the leather keepers (3) of the piece (1), in order to fasten both pieces (1, 2), fastening that is done by means of a screw (11) that is clearly seen in Figure 3.

[0021] On this piece (2), in addition to the D-ring (9) with the strip (10) commented previously, are fastened several elements through which the bucking of the girth to the saddle is carried out, among which elements can be highlighted two pairs of rings (12, 12'), in the shape of right trapezoids, so that the pairs (12) are fixed to the piece (2) by strips (13), with these rings (12) remaining fixed, while the pairs of rings (12') in the shape of right trapezoids are left free to be mounted on the free ends of the respective elastic straps (14) that join the interior rings (12) and the exterior rings (12'), as is seen clearly in Figure 3.

[0022] The corresponding adjustment straps (15) pass through the exterior rings (12'), in turn passing through the leather keepers (4) of the piece (1) in contact with the horse.

[0023] Through the interior of the elastic straps (14) are some nylon strips (16) that carry out two functions; on the one hand they constitute a means to limit the maximum extension of the elastic straps (14) and on the other hand they constitute a means of safety that keeps the rings (12, 12') joined together in case of breakage of the elastic straps (14).

[0024] As can be seen in Figures 3 and 4, the right trapezoidal rings (12, 12') are placed in a specific and determined way, keeping the rings (12) is a straight position, while the exterior rings (12') are rotated 180°, that is, placed inversely to the rings (12), all of this for the purpose of the adjustment straps (15) are oriented appropriately, that is, longitudinally, in relation to the buckles (17) by means of some elements (18) made up of double-pass buckles with security screw (19), through which pass the aforementioned adjustment straps (15).

[0025] Figure 4 shows thick arrows (20) that indicate how the horse is capable of pushing the girth according to its pulmonary needs.

[0026] Returning to the right trapezoidal rings (12, 12'), they are the ones in charge, due to their orientation and position, of collecting and directing the inhaling force of the horse towards the buckles and thus achieving a balance between the horse's inhalation and the fastening of the saddle.
