FR2583373A1 - EXTENSIBLE HINGE HOOK FOR SAILBOARD HARNESS AND DAGGER - Google Patents

Abstract

Harness for sail board and centre-board, characterized in that it comprises on the one hand a support (2) having in its central portion which is placed on the thorax of the user pairs of holes (3) distributed on the height of said central portion and at its lower portion notches (4) with holes (5/5') on either side of the notches, and on the other hand, a hook (1) provided with two holes (1) situated at the portion opposite to its curved extremity (1a), which support (2) and hook (1) are interconnected by an elastic link (6) comprising a knot at each of its extremities, said elastic link (6) slidingly passing through two of said holes (3) and through said holes (5/5') of the support (2) and through said holes (10) of the hook (1) and its extremities, which carry said knots, are engaged into two of said notches (4) in order to adjust the length and the tension of the elastic tie in order to enable the direct hooking to the harness at any location of the wishbone.

Description

 The present invention is characterized by a system allowing the improvement of harness hooks for the practice of windsurfing and dinghy sailing.

 Known devices of this kind require an accessory independent of the harness, characterized by two cords fixed to the "wishbone" (part that the user holds to navigate), allowing the harness to be hooked in order to relieve the effort of the arms and use body weight.

 The cords must be judiciously placed under penalty, according to the navigation speed, of being badly situated in relation to the center of gravity of the user. In addition, these cords form obstacles to the placement of the hands on the "wishbone".

 During the fast maneuvers, the cords often hang in the hook of the harness and in the fin of the float when the back of it goes into the "wishbone" following a fall of the rigging.

 The device according to the invention eliminates this major drawback by the outright removal of the two cords attached on either side of the "wishbone", and allows rapid attachment at any time and to any part of the " wishbone "according to the speed of navigation.

 I1 consists of a hook articulated by an extendable hinge retained by a bungee cord on a support fixed to the straps of the harness.

In the appended drawings given by way of nonlimiting example of one of the forms of the invention,
Figure 1 shows the device in place on the harness. The height adjustment of the hinged hook is done by changing the hole bead in Figure 5 (3) in coordination with the three holes in Figure 5 (4), knowing that the spaces between these holes are identical.

 The device must be set as high as possible, at the level of the sternal dimple. It must allow the lowering of the chin on the chest without discomfort.

If the device is set lower, the "wishbone" must be in height ratio.

 Figure 2 shows the device as a whole without the return bungee cord which has a knot at each end. Hook proper (1).

Hook support that attaches to the harness straps (2). The holes (4) allow to go out and put back the bungee cord while blocking the knot. The holes (5) and (5 ') larger than the holes (4) allow the bungee cord to pass with the knot in order to avoid undoing it when adjusting the height of the hook in Figure 2 (1).

 Figure 3 shows the device seen in profile. The pointta) shows the part which is hooked on the "wishbone", and the part (b) is bent to allow the return of the part (1) figure 2.

 Figure 4 shows the device seen from above. The hook support (2) follows the shape of the chest.

 Figure 5 shows the device with the calibrated bungee cord having a knot at each end (6) in the lowest position. (7) and (7 ') represent the passages of the strap which encircles the body. (9) represents the shoulder strap and (8) the crotch strap.

 Figure 6 shows the device in operation seen from the side. By pulling the arms, the "wishbone" is brought into the hook. When this traction is released, the force of the sail makes the hook pivot forwards and then stretches the bungee cord to the bent arm position in figure 7 or outstretched arms in figure 8. The device comes off smoothly when one borders the sail, the "wishbone" approaches the bust, the bungee cord relaxes gradually until voluntary release of the hook at the end of traction, and which comes back to place in rest position pressed on the chest figure 1.

 Figure 2 shows the omega shape of the holes (4).

 Device characterized by the use of polyamide nylon-like material or any other equivalent material.

Claims (6)

 1) Device improving the windsurfing harness and dinghy characterized by a support figure 2 (2) and a hook figure 2 (1) connected by a bungee cord having a knot at each end figure 5 (6) adjustable in height thanks to holes in Figure 2 (3) and (4) and allowing direct attachment to any location of the "wishbone" (part that the user holds to navigate) thanks to the extendable hinge effect.  2) Device according to claim 1, characterized by a calibrated bungee cord in FIG. 5 (6) provided with two nodes, connecting the part (1) and (2) in FIG. 2 via the holes (5), (5 ′), (4), (3), (10) and serving to hold and return the part (1) in FIG. 2 relative to the part (2) in FIG. 2.  3) Device according to claim 1 characterized by a system of holes, distance between the holes (4) and (3) Figure 5 identical for proportional adjustment. Omega shape of holes (4) with diameter identical to that of the bungee cord to block the knot of the latter, and diameter of the holes (5) and (5 ') and (3) larger to allow free passage of the bungee cord with its knots. All this allowing quick adjustment.  4) Device according to claim 1, characterized by a shape matching the bust, part (2) in figure 4.  5) Device according to claim 1 characterized by the rounding (b) Figure 3 allowing the pivot thereof.  6) Device according to claim 1 characterized by the use of polyamide nylon type material (plastic material resistant to ultraviolet, cold, hot, flexible and non-brittle), or any other material having these characteristics of high resistance and low density.
