Abstract

The present invention relates to a method of manufacturing a saddle tree and the tree thus produced. The method according to the invention for manufacturing a saddle tree comprising a pommel (1) or front withers and side bands (2) with rear cantle (3), the withers being bent is essentially characterized in that the pommel or withers and side bands are pieces made separately from a composite material comprising at least one upper ply of wood, at least one lower ply of wood and interposed between the plies of the layers of natural or synthetic fibers and / or wood and that the pommel (1) and the side bands with cantle are then glued with interposition between the tabs of the pommel and the side bands of an "L" shaped metal wall to which the stirrup doors are fixed on each side of the tree .

Description

The present invention relates to a method of

  manufacture of a saddle tree and the tree thus realized.

  A traditional tree consists of two pieces, the pommeau or tourniquet at the front and the cantle at the back, which, connected by lateral bands, constitute the

saddle structure.

  The pommel or tourniquet, the cantle and the bands

  side are usually made of wood.

  The wood allows easy attachment of the straps constituting the seat and more generally of the entire leather upholstery part. In traditional pommels, steel strips

  riveted with wood reinforce the tree.

  This traditional way of making the tree besides its

  weight has a number of disadvantages.

  The steel strips must be shaped by means of specific tools, which increases the cost of manufacture. Fastening these strips to the wood by riveting weakens

the pommel.

  In addition, the addition of a transverse metal reinforcement to the tourniquet stiffens the latter which thus presents an unattractive accentrated break with the risk of injury to the horse withers because of the rigidity of the

metal reinforcement.

  Solutions have been proposed using synthetic materials of the plastics type or

  resins, for example molded resin reinforced with fiberglass.

  European Patent Application No. 260192 discloses a pommel of this type which is integrally formed by a thin strip of a composite material and which comprises a rigid yoke terminating at its front lateral ends with flexible flat pads and a curved u-shaped back portion. A tree of this type is intended to receive a top or seat which is itself molded and glued. If you want to stretch on a tree of this type a traditional seat, it is necessary to resort to the traditional work saddler by a webbing that may deform the tree and make it unsuitable for proper seating. The tolerance to the deformation of these pommels is low, which reduces the possibilities of adaptation of the

saddle shape.

  In addition, these molded pommels all have the same shape.

  The invention aims to remedy these drawbacks by making a tree keeping the appearance of the traditional pommel on which a professional saddler can intervene to achieve the complete saddle and while being lightweight has the advantage of being more resistant than the traditional tree. For this purpose, the method according to the invention for manufacturing a saddle tree comprising a pommel or withers before and sidebands with cantle

  back, the withers being curved is essential-

  in that the pommel or tourniquet and the lateral strips 1 are made of a composite material comprising at least one upper ply of wood, at least one lower ply of wood and interposed between these plies of wood layers

  natural or synthetic fibers and / or wood.

  Advantageously, the tree according to the invention is

  consisting of a single piece.

  According to yet another characteristic of the invention, the pommel or tourniquet and the lateral bands

  with cantle are parts made separately.

  As defined above, made of wood composite material and natural or synthetic fibers and / or wood which are then glued with affixing to the legs of the pommel or withers and the side strips of an "L" shaped metal wall on which are fixed on each side of the saddle

stirrup doors.

  These provisions make it possible to make a saddle with a traditional aspect very light and which can receive

  easily the seat belt and the traditional cover

  tional. Other advantages and features of

  the invention will appear on reading the description below.

  1, is a plan view of a tree of the prior art, FIG. 2 is a diagrammatic view of a prior art tree, FIG. section showing the composition of the composite used to make the pommel or tourniquet and the sidebands with cantle, 1 - figure 3 is an exploded view of the pommel or tourniquet, - figure 4 is an exploded view of a sideband, FIG. 5 is a view of the assembly of the pommel or

tourniquet and sidebands.

  FIG. 6 is an exploded view of the assembly of the strips

side and pommel or tourniquet.

  As shown in FIG. 1, a traditional tree of the prior art comprises the bent knob 1, the preferred lateral bands 2 and the cantle

  preformed or multiply plywood 3.

  The bending of the pommel or tourniquet and the cantle is done in curve arc on both sides of the axis

medial longitudinal of the tree.

  These pieces are made of wood.

  It is customary to reinforce them with metal strips; a 4 at the withers, a 5 at the level of

  cantle and others 6 at the sidebands.

  These metal strips must be shaped beforehand

then are riveted to wood.

  This type of heavy tree, however, is fragile because of

  riveting including reinforcing metal strips.

  According to the method which is the subject of the invention, the pommel or tourniquet 1 and the lateral strips 2 are made in one

  composite material as shown in Figure 1.

  The cantle 3 can be realized in any known manner.

  This material obtained by pressing and / or molding comprises at least one upper ply 7 made of wood and at least one lower ply 8 made of wood, between which plies 9 1 of layers of fibers of synthetic materials with resins such as glass fibers are arranged. or carbon fiber or kevlar or any other natural or synthetic fiber

with a binder.

  Advantageously, the upper fold 7 and the lower fold 8

  include the same number of layers of wood.

  According to a preferred arrangement of the invention between the intermediate layers of fiber is disposed a layer 10 of wood constituted by a sheet of plywood or multipli having "n" plies of wood for example at

number of 9.

  The wood plies are made with crossed fibers, which

  allows to obtain a very good torsional stiffness.

  These provisions of the invention make it possible to reduce the warping of the tree during the subsequent torsion of saddle straps or in the event of bad

implantation of these.

  Depending on the criteria sought, use is made of

multiplied or plywood.

  FIG. 3 shows an exploded view of the pommel 1 or tourniquet with the upper plies 7 and lower 8 of wood, the layers 9 of fibers and the layer 10 of wood in

plywood or plywood.

  The fiber layers consist of all types of fibers, synthetic and / or natural and all suitable binders. The fiber top layer is preferably a fiberglass and resin composite and the lower fiber layer 1 with respect to the plywood or plywood middle layer is preferably a synthetic fiber-based composite layer, for example carbon or Kevlar and glass and resin or any other composition with equivalent qualities. In Figure 4 is shown a view of a band

  side 2 bent at the back to form a half

cantle 3.

  The lateral bands disposed on either side of the axis may or may not be contiguous at the level of the cantle. In the embodiment shown, they do not

are not.

  As shown, this sideband includes folds

upper wood 7 and lower 8.

  A layer of plywood or plywood in several thicknesses and two intermediate layers of composite material of natural and / or synthetic fibers and all

  suitable binders, between the layers of wood.

  The fibers may be glass fibers and the binder a resin. The tourniquet or pommel and sidebands are made to press for assembly and shaping

  then are cut by any known system and method.

  The pommel or tourniquet may have an indentation 11 in an arc in the front and has two legs 12 on each side.

other of the notch 11.

  As shown in FIG. 5, the lateral strips 1 2 are fixed by gluing to the lugs 12 with the addition of a metal part 13 which can be riveted to L whose vertical branch is in the axis of the lug 12 and the

  horizontal branch is in the axis of the band.

  FIG. 6 shows the exploded attachment of the tourniquet flaps and lateral bands, which is done by

14 splints in mid-wood.

  The stirrup door is riveted both by the metal piece 13 in "L" and on the leg 12 and on

the sideband.

  The entire tree according to the invention can also be made in one piece by pressing a composite as stated.
