FR2651477A2 - Craft with a wing-shaped sail structure fixed articulated to the top of a mast - Google Patents

Abstract

Craft with a sail including a sail structure made from a movable wing, which is symmetric, the 2 half-wings of which are not in the same plane, and connected to the top of a mast by an articulation. The sail structure consists of a canvass stretched over an articulated framework which can be folded or unfolded like a parasol so as to bring all of the canvass into a small volume gathered together around a handle (1) which is used for manoeuvring the sail, or, in contrast, to spread the canvass out close to a plane perpendicular to the handle (1). The framework, consisting mainly of 3 bars (2, 3 and 4) is kept open by a linkage system with 3 short bars (8, 9 and 10) one end of which slides along the handle (1). The cloth (12) close to the leading edge of the sail structure may be cambered with the aid of a batten which curves upon opening. APPLICATIONS: beachcraft, sports and pleasure boats, delta plane.

Description

FIXED WING VEHICLE ARTICULATED AT THE TOP OF A MAT

  The main patent (registration number 88 11785) relates to a sailing machine which comprises a wing made of a movable wing, symmetrical according to a plane, fixed to the top of a mast by a point situated under it in its plane. of symmetry using a hinge, this wing comprising an operating bar approximately perpendicular to the lift plane, the wing

  being made of 2 half-wings making an angle of about 40 between them. The pre-

  sente addition describes a variant of this sailing machine equipped with a foldable blade which makes it possible to make a sailboat, a windsurfing board, a wheeled machine

or a delta-plane.

  This wing consists of a canvas or the like (film, envelope, etc.)

  due to an articulated frame which can fold or unfold like a parasol so as to bring the whole canvas into a small volume

  around a handle or on the contrary to extend it close to a perpendicular plane

cular to this handle.

  The wing structure, shown schematically in Figures 1, 2 and 3, is

  mainly composed of a bar (1), or handle, used for the maneuver-

  vre of the wing, and at least 3 bars (2, 3 and 4) which are articulated at one of their ends connected to the top of the handle (1) so that it can be either

  pressed against this handle, or moved apart until it is noticeably perpetual

dicular.

  Figure 4 shows the folded frame.

  A canvas, or the like, is stretched between the bars (2, 3 and 4), constituting

  thus the 2 main planes (5 and 6) of the wing.

  A cord (7), cable, ribbon or the like or another canvas is placed between the bars (2 and 4) so as to be well tensioned when the frame is open,

  and thus constitutes a flexible link which can form a leading edge for the wing.

  The frame is kept open by 3 small bars (8, 9 and 10) each of which

  is not connected, at one of its ends, to one of the bars (2, 3 or 4) by a

  articulation, and at the other end to a part (11) common to the 3 small bars-

  res (8, 9 and 10), this piece (11) sliding along the handle (1) when the wing is folded or unfolded. It is the blocking of this part (11) at one of its extreme positions by means of an appropriate system which blocks the frame in

  open position, use position.

  Alternatively, to improve efficiency, the space between the 2 bars

  res (2 and 4), close to the leading edge of the airfoil, comprises a canvas (12) or the like connecting these 2 bars (2 and 4), this canvas being able to be equipped with a

  or several flexible slats (13) long enough to bend as soon as the car

  lure is open in position of use, because these slats (13) are corner-

  between the fixed point of the top of the frame and the flexible link (7), rope or

  another, taut which constitutes the leading edge of the wing.

  According to an improved variant, the blade comprises another triangular piece (14) of fabric, canvas or the like, stretched (open blade) between, on the one hand, the flexible link (7) which constitutes the leading edge of the blade and, on the other hand, the 2 parts of fabrics (5 and 6) which constitute the 2 main planes of the airfoil, this piece of fabric (14) being able to cover the 3 small bars (8, 9 and). According to a variant, the base of the mast (15) is not fixed to a boat hull but comprises, as shown in FIG. 5, a small seat (16) on which one sits to use this wing in delta- plane. The machine is then guided by

  the orientation that is given to the bar (1) relative to the mast (15).

Claims (6)

  1. Sailing craft according to any one of the claims of the main patent   pal characterized in that the blade consists of a canvas or the like (film, envelope, etc.) stretched over an articulated frame which can fold or unfold like an umbrella so as to bring all the canvas into a small volume gathered around a handle (1) or on the contrary to extend it   close to a plane perpendicular to this handle (1).   2. Sailing machine according to claim 1, characterized in that   the frame of the wing is mainly composed of a bar (1), or man-   che, used for maneuvering the wing, and at least 3 bars (2, 3 and 4) which are articulated at one of their ends connected to the top of the handle (1) so that they can either be pressed against this handle , or spaced until they are substantially perpendicular, a fabric, or the like, being stretched between the bars (2, 3 and 4), thus constituting the 2 main planes (5 and 6) of the   wing, a cord (7), cable, ribbon or the like or another canvas being placed   created between the bars (2 and 4) so as to be well tensioned when the frame is open, thus constituting a flexible link which can act as the leading edge for the wing. 3. Sailing machine according to claim 2, characterized in that the frame is kept open by 3 small bars (8. 9 and 10) each of which   is connected, at one of its ends, to one of the bars (2, 3 or 4) by an articulation   culation, and at the other end to a part (11) common to the 3 small bars (8, 9 and 10), this part (11) sliding along the handle (1) when folded or unfold the sails.   4. Sailing machine according to claim 3, characterized in that   The space between the 2 bars (2 and 4), close to the leading edge of the car   lure, comprises a canvas (12) or the like connecting these 2 bars (2 and 4), this roof   it being able to be equipped with one or more flexible slats (13) long enough to bend as soon as the airfoil is open in the use position, these slats (13) being wedged between the fixed point at the top of the frame and the   flexible link (7), rope or other, taut which constitutes the leading edge of the car   lure. 5. Sailing machine according to claim 4, characterized in that the   wing comprises a triangular piece (14) of fabric, canvas or the like,   of (open wing) between, on the one hand, the flexible link (7) which constitutes the leading edge of the wing and, on the other hand, the 2 parts of fabrics (5 and 6) which   constitute the 2 main planes of the wing, this piece of canvas (14) can   before covering the 3 small bars (8, 9 and 10).   6. Sailing craft according to any one of the preceding claims   characterized in that the base of the mast (15) has a small seat (16) on   which one sits, the machine, used in delta-plane being then guided by the orient-   tation that is given to the bar (1) relative to the mast (15).   Erratum Brevet n C.A.
