Abstract

THE SUBJECT OF THE INVENTION IS A DETACHABLE MAST FOR SMALL BOATS. FOLLOWING THE INVENTION, THE MAST IS CONSTITUTED BY A PLURALITY OF TUBULAR ELEMENTS WHOSE ASSEMBLY AND DISASSEMBLY CAN BE CARRIED OUT EASILY AND QUICKLY WITHOUT TOOL, SLEEVES BEING PROVIDED TO ENSURE THE FIXING OF THE ELEMENTS. IN THE EXAMPLE REPRESENTS THE MAST INCLUDES FOUR STACKABLE ELEMENTS 1, 6, 7, 11 FORMING RESPECTIVELY FOOT, BODY AND MAST HEAD. THE SUPERPOSITION IS OBTAINED BY PARTIAL AXIAL INTERPENETRATION OF TWO CONSECUTIVE ELEMENTS. TUBE 1 INCLUDES A PART 3 OF SELF-LUBRICATING MATERIAL, A RELATIVELY ELASTIC PART 4 FORMING A STOP FOR THE FEMALE PART OF TUBE 6, A RING 5 OF RIGID MATERIAL ENSURING THE FIXATION OF PARTS 3 AND 4 ON THE TUBE 1. A PROVISION IDENTICAL IS PROVIDED FOR ASSEMBLY 8-9-10 OF TUBE 7 AND FOR ASSEMBLY 12-13-14 OF TUBE 11. APPLICATIONS: REDUCED OVERALL MAST FOR TRANSPORT, ESPECIALLY FOR SAILBOARDS, Dinghies and SAILBOATS.

Description

M Attainable for light sails.

  The invention relates to light craft such as windsurfers, dinghies, sports whose practice is

in booming growth.

  Its subject is an advanced mat whose particular constitution makes it possible to divide it very easily for transporting in elements of short length without in any way impairing the qualities of solidity and rigidity

required during use.

  It is known that we currently use for windsurfing masts whose length can not be changed, which therefore have for transportation disadvantages often unacceptable Loading on a car increases the longitudinal size of the latter In addition, a fixation providing sufficient security may not be possible in many cases. Moreover, if the serious inconvenience mentioned above is not taken into account, the same impossibility

  to house such a mat in the living quarters.

  The present invention aims to remedy all these drawbacks According to the invention, the mat is constituted by a plurality of tubular elements, at least two, the assembly and disassembly can be performed

  easily and quickly, without tools,

  particular provisions being provided for the liaison

  closes between two contiguous elements.

  Under these conditions, it is possible to obtain at will any desired length of mat, this being a function of

  the length and number of constituent elements used.

  It is also possible to achieve different rigidity mat (flexible, medium, steep) using tubular elements of different rigidity or adding by any known means (such as gluing or welding) to the constituent tubular elements or only some of those reinforcing tubular elements, either

interior or exterior.

  An embodiment of the invention will be described below.

  with reference to the accompanying drawing without limitation.

  This drawing represents a mat comprising four elements to

to assemble.

  In the assembly shown in the drawing, the m is formed of four tubular elements with partial axial interpenetration. 1 denotes the tube comprising the base 2 at its lower end and at its upper end the assembly

  bearing the references 3-4-5 constituting the means of

with the adjacent tube.

  The second tubular element is designated by the reference 6.

  The third carries the reference 7 and comprises in the lower part the assembly designated by the references 8-9-10 constituting the fitting means with the previous tube, while the fourth element 11 forms the head of the mat comprises its lower part the assembly designated by the references 12 13 14 constituting the means of fitting

with the previous tube.

  The base of the tube 1 is provided with a sleeve 2 and constitutes

clutch support.

  The assembly 3 4 5 comprises a part 3 intended to penetrate

  into the female tube 6 of sufficient length.

  This part 3 is at least covered with a self-adhesive material

  lubricant also ensuring the tightness, while the sleeve 4, slightly pear-shaped in this example, can be

3 2509250

  favorably composed of the same material as part 3,

  but in any case it must have a relative elasticity

  This stop is made perfectly effective by the presence of the ring portion 5 and formed by a perfectly rigid material. The assembly 3 4 5 is made integral with the tube 1

  by any known means such as welding or gluing.

  The assembly 8 9 10 secured to the tube 7 is strictly identical to the assembly 3 4 5 Part 8 is provided to penetrate through the upper end of the tube 6 It is the same of the assembly 12 13 14 of the end of the tube 11, the part 12 being intended to penetrate

the upper part 16 of the tube 7.

  The dotted line 17 represents an additional tubular element introduced into the tube 6 and fixed thereto so as to form a reinforcement intended to increase the rigidity of the tube 6. When this tube 17 has the same length as the tube 6, the outside diameter of the

  Part 3 is obviously planned accordingly.

  It would be m Ome of the ends 8 and 11 if any.

  The sleeve portions, respectively 4, 9, 13 of the

  different tubular elements represented have favored

  This diameter increase has the practical advantage of moving the sail slightly further away from

  connecting two successive elements.

  From the description that has just been made, it is easy to

  note that such an assembly is easily removable, so that once the dissociated elements, as shown in the figure, the entire met occupies a short length (about a quarter of the length of mats o 9 z 5 o current) It is also understood that the assembly of the various elements can be done very quickly and that the rigidity of a mast thus constituted, increased

  if necessary by means of additional elements

  reinforcements as indicated, is absolutely satisfactory. It is recalled that the tubular elements constituting the mast may be two (minimum) or more depending on the use cases, the ends of the assembled elements may be both a mile and a female, provided that at the points of interpenetration corresponding one of the ends considered is male and provided

one sleeve and the other female.

  It is understood that the invention is not limited to the example described and illustrated which has only been given to

  indicative, and that, without departing from the scope of the

  vention, all variants may be made concerning in particular the number of constituent elements and their dimensions, in order to be able to constitute at will mats of different length (for example, in the case of windsurf boards, for use with a storm sail or by a child) It is the same with regard to the rigidity of the components of the mast whose diameter and composition can be

  chosen according to the effort required of them.

  It is in these conditions possible to be advantageously disposed in the same mit stiffness elements

  different for the head, body and base of the mat.

  It is also possible to have components of different length and stiffness

  interchangeable depending on the use case.
