Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a fixing device between a mast base and a mast base holder, or a mast base holder, which can be moved while being held along a mast base, and which is capable of moving while being held along a mast base and a mast base holder. comprising at least one locking element for closing or releasing a fixed state, such as the fixation of a mast base holder which can be fixed in position, said locking element being movable via a foot pedal arranged on the upper side of the sailboard; It was done. This invention relates to a device for removably fixing a heel mast to a sailboard.

BACKGROUND OF THE INVENTION Devices and intended purposes of this construction include, for example:
It is described and illustrated in West German Patent Application No. 2843 551.

A foot pedal provided in the known structure can be used to move the sailboard as required to unlock the mast base holder in the guide groove so that the longitudinal position of the sailmast can be adapted to the prevailing factors. It can be pressed down by the user. Additionally, it is known to utilize a foot pedal to release the lock between the mast base and the mast base holder so that the mast base can be removed from the mast base boulder.

(Problem that the invention seeks to solve) In the above case, when the foot pedal is released, for example due to spring pressure, the foot pedal is raised to re-enter its operating state and is automatically locked. In this operating state, the foot pedals protrude significantly from the top of the sailboard, although they do not form an obtrusive bulge.
There is a risk that the foot pedal will disengage unintentionally, so that unlocking cannot be prevented.

There is thus considerable danger to the user of the sailboard.

It is an object of this invention to first provide a device for removably fixing a sailmast to a sailboard, which has a limited structure and intended purpose, so that the foot pedal does not interfere with the locking position of the locking element on which it is actuated. The goal is to develop the product in such a way that it does not cause any damage to the product, and prevents unintentional release of the foot pedal.

(Means for solving the problem) ゛ This purpose is to
This is achieved in that the foot pedal can be sunk into the idle position.

The essential advantage in the development of this invention is that the foot pedal
This consists in that in the locking position of the actuating locking element it is sunk into the upper surface of the sailboard or of the component housing the foot pedal. In this position,
The foot pedals do not form an obtrusive bulge for the user standing immediately adjacent to the foot pedals on the sailboard, simply because the foot pedals are submerged.
It is impossible to unintentionally press down on the foot pedal and therefore unintentionally release the associated lock. With the development of this invention, two essential advantages can be achieved. Unintended disengagement can also be achieved by locking the foot pedal in its activated state. However, with this method, the foot pedals form an obtrusive bulge that interferes with the user standing on the sailboard during sailing.

Particularly in foot pedals with relatively large surface dimensions, it may be advantageous to limit the downward movement of the foot pedal in the submerged play state via stops, grips or the like. This can be arranged via a stop arranged for the foot pedal or via a stop on the locking rod (FIG. 2).

In the development described in claim 3, if the operated foot pedal is not depressed due to the spring force, it is brought into an active state as described in claim 4. It is particularly advantageous if it is inserted so that Due to the presence of a corresponding spring, maintaining the foot pedal in its idle position is achieved. However, a further development according to the invention is not limited to foot pedals subjected to the aforementioned spring forces, but is also advantageous in the case of foot pedals that are not prestressed. In this type of foot pedal, for example, the locking mechanism of the present invention can prevent the foot pedal from snapping under the action of gravity and causing injury to the user in that position when the sailboard capsizes.

In order to be able to sink the foot pedal into the locking position of the locking element on which it is actuated, it is necessary to achieve a force-locking or form-locking connection between the foot pedal and the locking element or its rod. This combined state is the subject matter of claim 5. Several possible developments exist for this type of coupling.

The development according to claim 6 recommends the use of a simple lever principle for operating the locking element or its rod.

A further development of the invention is contained in claim 7, in which the connecting piece is pivotably arranged in the foot pedal.

This development is recommended not only for its MW and spatial reasons, but also because it also makes possible the configuration according to claim 10, in which the spring is connected to the foot pedal and the coupling. Both of the pieces have east reset Akebono.

The embodiment according to claim 8 is advantageous for ergonomic reasons, in that the connecting piece can be actuated by horizontal rocking into its connected or uncoupled state.

The arrangement according to claim 9 provides a compact device, in which the elongated hole simultaneously limits the rotation of the connecting piece. , therefore no special stop is required to limit this rotation.

The embodiment according to claim 11 is likewise distinguished not only by its simplicity, but also by the fact that the locking element or its rod can be connected to the foot pedal when the foot pedal is both in the sunken idle position and in the non-sinking operating state. It also has the feature of being able to connect or disconnect. Therefore 3! l! Manually operating the coupling piece to detach it is extremely simple, since it is only necessary to push down the operating member. Resetting the connecting pieces to the connected state is effected by a spring. Locking of the foot pedal in its sunken idle position is likewise ensured by means of the form-locking connecting link.

Claim 12 includes a further device for locking the foot pedal in its sunken play position. This means that the foot pedal is moved by means of a locking projection through a slotted link or a pivotable holding piece. What is claimed in claim 13 encompasses a development in which the foot pedal can be moved longitudinally, the bearing of the foot pedal being arranged on an eccentric disc to move the foot pedal longitudinally and displaceably. It is designed to be able to swing horizontally.

In one development, in which the foot pedal has the function of locking the mast leg in at least two positions in the guide groove, it is recommended that the foot pedal be formed in such a way that it can be submerged in the existing guide groove. be drunk. In other cases,
Special recesses will be required in the sailboard for the foot pedals (
(Claim IllllgJ514).

With the development according to claim 15, the risk of injury due to crushing between the foot pedal and the open end that picks it up is avoided.

In the sixteenth aspect of the invention, the foot pedal 1oif! At least one damper is provided on the foot pedal for limiting l.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Three exemplary embodiments of the invention will now be described in detail with reference to simplified drawings.

By disengaging the coupling piece 21, the foot pedal 15 can be swung horizontally into its sunken play position, via a coupling recess 27 arranged offset on the periphery of the pivot axis 16. , in this sunken idle position a connection with the rocking arm 22 is possible, so that the foot pedal 15 can be locked in its idle position. The downward movement of the foot pedal 15 is limited by a stop 28 fixed to the guide track 8, which stop 28 limits the sunken play position and the lower end of the rocking state. This can be achieved by operating the foot pedal 15 to release the lock.

The second embodiment shown in FIG. 2 differs essentially from the first embodiment described above in the shape of the foot pedal, designated 31, and the shape and arrangement of the connecting piece, designated 32. ing. The foot pedal 31 includes a vertical side g133 and a front R34 bent in an arc shape around the pivot axis 16, and there is a risk of the foot pedal 31 becoming stuck between the four ends surrounding the foot pedal 31 and the foot pedal 31. is prevented. A stop 35 is provided at the lower end of said wall 34 and acts in combination with the damping surface of the guide track 8 to limit the upward movement of the foot pedal 31 or as shown in FIG. The operating conditions are limited. In the idle state shown in FIG. 3, a stop (not shown) on the connecting rod 13 prevents the foot pedal 31 from being depressed deeper than the position shown.

The connecting piece 32 includes a cross piece 36 and two side walls 3
7 and provided on the two II M 331 of the foot pedal a1, about a horizontal swivel M38 supported on the side wall 33, between the connected and uncoupled state. It is designed to be able to swing horizontally. The rocking motion is determined by the length l of the elongated hole 39 of the connecting piece 32, in which the pivot shaft 16 of the foot pedal 31 engages. The connecting piece 32 is moved upward, for example, by the torque spring 41 disposed on the pivot shaft 16, so that the pivot shaft 16 is engaged with and placed on the lower end of the elongated hole 39! ! ! The torque rod 41 is made up of a plurality of coils surrounding the pivot shaft 16 and has two legs 42 and 43 at its ends. is supported by a buffer body 44 fixed to the guide track, and the leg 43 is pressed against the crosspiece 36 of the connecting piece 32 at a distance from the pivot axis 38. Therefore, with respect to the connecting piece 32 A rotational movement directed in the direction of arrow 45 is transferred.

On the side remote from the pivot axis 38, the actuating member 4 of the connecting piece 32
