Definitions

  • the invention relates to a surf-board or other gliding vessel having more than one mast and sail such as a tandem surf-board, comprising interconnectable parts which can be disconnected.
  • Surf-boards are generally known and their popularity is rapidly increasing because they open a new form of sailing sport to large groups of the population.
  • the best known surf-boards are so-called mono- surf-boards, which means that they have only one mast and sail and only offer place to one person.
  • tandem surf-boards having a board out of one piece upon which two or more masts are placed and accordingly offering place to two or more persons. With such a tandem surf-board higher speeds are possible and for said reason they are very attractive.
  • the disadvantages of said known surf-board are:
  • Purpose of the invention is to provide a surf-board system offering the owners of mono surf-boards of the same type to combine them to tandem surf-boards or even multiple surf-boards.
  • each one of said parts is formed by a complete mono surf-board or vessel each being formed at its stern and stem respectively such that the st-em of a next surf-board or vessel by its form fits into the stern of a preceding surf-board or vessel and the reverse
  • each part itself is a mono surf-board and said parts fit into eac-h other like a male-female construction due to which they can be interconnected in any desirable number without disturbing the properties when used as mono surf-board.
  • each surf-board has a stern of a form such that the stem of an identical surf-board can be enclosed and mounted into it. In this way two or more surf-boards in a simple way can be interconnected to a multiple surf-board.
  • the sailing properties of the mono- no surf-board are not effected neither by the shape of stem and stern nor by the recess in the stern.
  • the surf-boards which according to the invention can be interconnected to a tandem-surf-board or a multiple surf-board,are entirely identical
  • the invention also relates to those surf-boards which are identical at stern and stem but inbetween different to be able to combine junior surf-boards with surf-boards for grown-up people.It even is possible to combine surf-boards which are not identical at all but of which one has a stem which fits into the stern of another surf-board.
  • the mono surf-board suitable to be combined to a multiple surf-board at the location of the front end of the recess and at the locaton of the stem has been provided with connecting members which together form a connection.
  • connecting members By the form fitting insertion of this stem in the recess of the stern relatively few and simple connecting means are sufficient. Often a connection of the stem in the front end of the recess will arready be sufficient.
  • members at the rear ends of the legs of the stern extending on both sides of the recess which lock against upward movement a stem placed in said recess.
  • connection can be obtained by providing those parts of stem and stern which fit upon each other at least locally with the complimentary parts of a velcro fastener.
  • Velcro fasteners have the advantage to enable a quick connection which gives way however upon overloading.
  • connection between the front end of the stem and the front end of the recess can be obtained in that the surf-board at the front end of the recess as well as at the stem has been provided with connecting members which together form a connection.
  • the stern at the front end of the recess and/or at the rear ends of the legs of said stern has been provided with cams extending above the recess and adapted to engage the top surface of a stem placed within the recess. Due to this in combination with the upwardly inclined side faces of the legs of the recess which side faces deliver a locking downwardly a locing in all directions is obtained and provisions then. still only are necessary to prevent disengagement in axial direction.
  • Surf-boards having centre boards are well known and it is also known that such a centre board bas been removably inserted within a longitudinal slot.
  • the surf-board according to the invention can be provided as well with such a removable centre board. This is desirable not only for transportion purposes, as is well known, but to prevent that too many centre boards effect the steerability of a combination of two or more surf-boards according to the invention.
  • the surf-board at its stern has been provided with a hollow space which, with the exception of the rearwardly open insert opening is closed in principle and has an inner shape which is equal to the outer form of the stem and that openings are provided in the stem and in top and bottom portion of the stern of a form and location such that in case a stem is placed into the stern opening both surf-boards are interconnectable by a connecting member which can be inserted through the in line lying openings.
  • a connecting member can be a pin or a plurality of pins but preferably said openings are formed by longitudinal slots and the connecting member has the form of a centre board such as e.g. one of the centre boards of the two or more mono surf-boards which are to be interconnected. In this way without additional elements a tandem surf-board can be obtained having the same or almost the same steering qualities as a mono surf-board.
  • Figure 1 shows a-tandem surf-board comprising a front surf-board 1, a second surf-board 2.
  • the surf-board 1 has been provided with a mast 3 with sail 4 and the surf-board 2 with a mast 5 with sail 6.
  • an insertable centre board has been provided formed by a plate mounted within a slot provided for that purpose. This is well known.
  • the surf-board 1 has a similar slot and if so desired a centre board can be inserted there as well.
  • FIGS. 2 and 3 show one of the surf-boards of Figure 1 at larger scale.
  • the cross sections are indicated which are found as well in the timber plan indicated in Figure 4.
  • the surf-board at the stern has been provided with a recess 8 open rearwardly and having side flanks 9 and 10 respectively diverging upwardly and joined at the location of a flat strip 11.
  • This recess can be made as well with a bottom as indicated with the line 8'.
  • the stem generally indicated at 12 has side flanks 13 and 14 as well as a flat front piece 15 which surfaces 13, 14 and 15 in shape fit upon the surfaces 9, 10 and 11. AT the location of the surface 11 and the stem 12 velcro fastener belt can be provided.
  • the interlocking of the stem 12 in the recess 8 of a stern can be obtained in a simple way by providing the recess upwardly of abutting members e.g. in the form of cams 19, 20 and 21.
  • the interlocking in axial direction then in a simple way can be obtained by means of the pin 22 which can be inserted through an eye 23 of the cam 19 and into the bushing 24 of the stem.
  • velcro fastener belt can be applied upon the surface 11 or over the seam of the joined stem and stern.
  • FIGS. 5, 6 and 7 show a different form of interconnecting at a location of the rear ends of the legs which on both sides of the recess 8 form the stern.
  • the belt 26 comprises a left hand part secured to one leg of this stern by means of the connecting strip 27 and a right hand part 28 connected to the right hand portion by means of a connecting strip 29. Both ends are interconnected by means of a tension member 30 of known construction.
  • connection by means of the pin 25 is shown more in detail in figures 8 to 10 inclusive.
  • plate 33 Upon the surface indicated with 11 in figure 3 plate 33 has been mounted shown in figure 9 which with bent ends 34, 35 lies in one plane with top surface and bottom surface respectively of the stern. Said plate 33 hastwo bushings or sleeves 36, 37 spaced apart and at the inner side,which means between the outwardly turned surface of the plate 33 and the stern,which stern to this end has been provided with a recess 38 which as shown in Figure 9 and 10 is a little bit larger than the bushings 36, 37.
  • the stem 32 in the same way has been provided with a plate 39 with bushing 40.
  • Said bushing 40 has a length such that it fits inbetween the bushings 36 and 37.
  • connection atthe outer ends of the stern can be performed as shown in Figures 5 and 7 inclusive, which means with a tension belt, or in the manner as shown in Figures 2 and 3 by means of the cams 20 and 21.
  • Other combinations of connecting means and other embodiments of connecting means of course are possible.
  • Figures 11 and 12 show a preferred embodiment according to which the surf-boards 50 at the stern have a recess 51 which is only open at the rear end and the inner form of said recess 51 is such that the stern 52 fits exactly into the recess 51.
  • the two surf-boards 50 are interconnected by means of a centre board 53 whcih extends through slots 54 and 55 of top wall and bottom wall respectively of the recess 51 and through the slot 56 of the stern.
  • This centre board 53 can be a centre board which also can be used in the slot 57 of a surf-board 50 when used as mono surf-board.
  • the Velcro fastener mentioned above is a fastener well known in textile between two faces one having a plurality of loops the other a plurality of elastic hooks.
