Hooking and unhooking system for harnesses

The present invention relates to a hooking in and unhooking system according to the generic term of claim 1. tin Such a system is used in shipping and especially with sailboards and surfboards.

The known devices allow a reduction in the physical exertion of force on the arms during exercise sporting activities, especially surfing, water skiing en usuj. There is a difference in these devices man:

provided a board having fastening hooks is. The fastening hook can be in a connecting element intervene that can be thrown off by the user and that with its ends with a Uerankerungteil such as the boom of a sailing board a.

The main problem with this type of harness resides in the rigid piece forming the hook with which the user is must hook to reduce the pulling force on the arms. When the user is in trouble or simply disengaging from the anchorage I wish, I often find it difficult, that to unhook the fastening element held in the hook, because the hook is generally firmly connected to the board is.

The above French patents include a solution to the problem relating to the dropping of the Uerbindungselementes. The fastening piece is in this Case formed by an open hook which is mounted on a pivot pin, which by a trigger guard is blocked. This allows a closed position or a hooked position and an open position Position or take a unhooking position, the latter by pulling a cord i. a. with the thumb of the user is achieved. The main disadvantage of this arrangement lies in the cord connected to the thumb » which hinders the movements of the user. In order not to hinder the movements, the cord must be very relaxed be; but in this case it is required

Pull to unhook the system very difficult to effect.

The object of the present invention is in this regard to achieve an improvement. This problem is solved according to the characterizing features of the claim 1. Further advantageous refinements of the system according to the invention are set out in the subclaims removable.

In the system according to the invention, the user is completely free in his movements. For the Aöuiur ^f des

1D fastener, no cord is required-thanks a spring, which returns the hook to the open position, is the only way to cancel the Tension ensures that the connector will be thrown off. The system for hooking in, in turn, is different not from a harness with a fixed hook. The opening position of the hook downwards and forwards allows the connection element to be hooked into the hook without the aid of the hands by means of a movement of the body, the connecting element being guided into the hook opening and, according to the invention of FIG The hook moves into the closed position when a train is exerted on it.

The system for hooking the harness into the ¹ ″ connection element attached to the liner is formed by a rigid plate on which two supports parallel to one another and perpendicular to the plate are attached in the center. The two supports are

v / orne with zuiei barriers, through which a movable or immovable axis passed through is. Around this axis and perpendicular to the board can be a swivel rigid, semicircular curved element, which forms a hook that attaches to the axle is or is not, but is necessarily movable with respect to the supports. Between the fixed part, the formed by the sinker / post assembly and the movable hook is a spring or some another mechanical fitting with elastic properties (e.g. a semi-rigid metal sheet or a Rubber band) arranged, which allows sufficient movement to be generated. The shackle of the hook lies when it is not attached to the connector on the upper part of the board. The opening of the semicircle therefore extends downwards and slightly towards warn with respect to the user's chest, the The angle between the axis of symmetry of the semicircle forming the hook and the horizontal is approximately 120 degrees

2Cl. When the user pulls the hook into the fastener hangs, the spring force must be weak enough to allow the hook to pivot about the axis, so that it can move into a position that prevents the connecting element from being thrown off. Of the between the axis of symmetry of the semicircle forming the hook and the horizontal is the angle now less than 30 degrees. If the.

Figure 2 is a perspective view of the return spring of the hook in the open position.

The ventral and chest strap 1 of the support harness supports a metallic plate 2 via zujei recesses 3 and k for the passage of the strap. In the center of the board and one centimeter apart, two supports 5 and 6 2 cm long and 1 cm wide are welded on. In the center in front of the middle of each support a hole 7 and B is made, through one

2R axis is 3, which is welded in this exemplary ührungsbeis ^ri iel to the supports. The end of the hook 10 of the harness is arranged around this axis in the form of a closed loop, which hook is formed by a straight part followed by a semicircle. A metal wire, which forms a spring, is also wound around this axis. One of the angled ends of this

. Metal wire is supported at 11 on the initial part of the hook and the other end at 12 on the lower edge of one of the zuiei supports. When the support harness is in the hooked position, which is shown here by dashed lines, the hook is held in the connecting element, which in this embodiment is formed by a cord 13 which, at each of its ends, is connected to the boom, in the case of a sailboard. is attached.

A single fastening support 5 is shown in FIG. It carries an axis 9 around which the end of the hook 10 is arranged in the form of a closed loop is. A metal wire 15, which forms a spring, also extends around this axis. One of the angled Ends of the metal wire is supported at the beginning part of the hook and the other end is supported at 12 on the lower edge of one of the zuiei holding supports.

One can easily understand the scope of this invention in all sports or other activities, who make use of a support harness, which allows the Uerbindungselementes to be thrown off quickly and easily without the direct help of the hands, for example with a sailing trapeze and with water skis.

The word part of the invention lies essentially in the Ease of throwing off the fastener,

The advantage is also the speed of unhooking thanks to the spring that immediately brings the hook into the open position when the user presses the The tensile force on the connecting element cancels.
