Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a device comprising a mast connecting universal joint having one end connected to a mast and the other end connected to a support member, the device being used by being attached to a predetermined position. The present invention relates to an apparatus in which at least a portion of the support member is received in a recess in the upper surface of the sailboard and is securely connected to the sailboard when the sailboard is in use.

Various implementations of the above device are known. In one embodiment, the support member comprises a pin extending into a vertical sleeve provided in the sail board. One end of the cord is secured to the free end of the pin. The other end of the cord is secured to the bottom of the sleeve. This cord is long and does not prevent separation of the support member and sail board. The role of the code in this case is
The goal is to prevent floating sailboards from being swept far away from the rigging.

The advantage of the above device compared to other known designs consisting of so-called retaining cords is that the retaining hood does not get in the way during sailing and can catch the sailor by surprise, causing him to fall off the sailboard. This is something that never happens.

A common shortcoming of currently available products is that they allow sailors to quickly and easily attach support members to the sail.
It is impossible to insert it into the recess of the board, and if necessary, there is a possibility of injury when working with hands. When a sailor climbs to the top of a sailboard in deep, choppy water, the support member often becomes detached from the sailboard when this is neither necessary nor intended.

Devices are also known for changing the position of the mast and moving it to one of at least two positions along the length of the sail board. An essential aspect of this device is that when moving the mast to the other position, the elastically locked mast must be lifted, and the mast is elastically locked again in said other position. Lifting the mast vertically requires great effort and is considered disadvantageous because the sailor must hold the mast in an unstable state of equilibrium.

The object of the present invention is to provide an improvement in this respect by providing an overload clutch, preferably combined with an easy-to-operate device for moving the mast in the longitudinal direction of the sail board.

In the device of the reference example described in the first part of the description of the invention, the support member is always spring-loaded and is provided with a device configured such that a secure connection is no longer possible only when the spring force is overcome. The above objectives can be achieved.

If any part of the sailor's body becomes caught between the falling mast and the sailboard, there is no risk of injury to the body part, and the support member automatically retracts to the working position after it has been safely removed. The spring force must be selected to As a result, the sailor does not have to enter the water solely for the purpose of reconnecting the sail ball and rigging.
If the relative positions of the sailboard and rigging momentarily become unfavorable and prevent the automatic engagement of the claratch, the sailor should rock or rotate the sailboard slightly to prevent automatic retreat. Just start it.

Preferably the spring is a tension spring and is housed in a duct extending to the tip of the sail board. This duct opens into the top surface of the sail board. Preferably, a spring tensioner is arranged at the mouth of the duct. This allows the spring to be easily and quickly installed or removed, for example in the event of replacement or renewal.

The spring can be a rubber spring. Rather than being circular, the support member can be, for example, in the shape of an inverted truncated pyramid.

According to a preferred feature of the invention, the spring constitutes a return spring for the support member in any position in which the mast is in use, and the longitudinally slidable slide is connected to said slide. This is a spring constituting a return spring that moves the holder to a position where it is releasably locked. First, less space is required within the sailboard body because a single component is used to perform two functions. The less space required lends to strength and stiffness, which are extremely important in surfboards. On the other hand, the spring has the same release characteristics at all positions of the mast. Another advantage is that as a result of the use of identical parts, the device is less expensive and less likely to malfunction.

The cut-out recesses and guide grooves in the sliding member may be longitudinal grooves in the board itself, and according to a preferred embodiment of the invention, the carriage, the support member and the spring are accommodated inside the slot in the sail board. It may also be a groove provided in a box which is slidably arranged and is elastically locked. With the embodiment described below, the device according to the invention can be easily installed and removed at any time, making repair and cleaning operations extremely easy. Additionally, complex machining of bulky sailboards is not required.

According to another feature of the invention, the slide has a support member and a pedal receptacle, which sides are connected to the slide and are movable relative to the slide within the slot. , guided by pins within the grooves of the sailboard or grooves formed in the sides of the insertion box.

According to a further advantageous characteristic of the invention, the receptacle of the support member is of integral construction inside the slide member.

According to another important feature of the device according to the invention, the spring consists of an elastic rope or the like wrapped around a roll, the roll being rotatable at the end of the groove or box and at the pedal. and both ends of the rope are connected to the support member.

When a pre-tensioned elastic endless rope is stretched around the roll, a constant force is applied to hold the slide in place and the support member always has an equal release characteristic.

An important feature of the invention is that the slide can be brought into the open state by pressing down on the pedal and pushing the slide with the foot to change the slide in the longitudinal direction. The pedals are always close to the surfer's feet.
The above features provide an important advantage over known devices, since two-handed mast transitions, which require control of the diagonal beams, are no longer required. An advantage provided by another feature of the invention is that the mast remains stable even during transition.

According to a further feature of the invention, the support member and the associated receptacle are conical in shape, so that tilting during release is avoided. According to a further feature, the taper of the support member and the receptacle can be adjusted stepwise or continuously.

At least one end of the groove formed in the sailboard for receiving the slidably mounted box is suitably beveled to facilitate removal of sand and other foreign matter.

Other features and advantages of the invention will be apparent from the claims, the drawings and the following description.

Representative embodiments of the invention are shown in the drawings.

The device shown in FIG. 1, which is a reference example related to the present invention, serves to connect a mast 1 to a sailboard 2, and only the lower end of the mast is shown, and the mast connection universal joint 3 Fixed. Since the universal joint itself is well known, details are not shown. By means of this universal joint and the intervening support member 4, the mast is supported on the sailboard 2.
The support member is known, for example, from West German patent application no. 2449636 filed by the applicant;
It consists of a toothed bar defining a plurality of different connection points connecting the mast to the sailboard.

When the device is in the illustrated position of use, the portions 5 of the support member 4 interengage with mating recesses in the upper surface of the sail board 2. This part 5
is an inverted pyramid with its tip cut off, and one end is a rubber spring 6 housed in a duct 7.
The duct 7 extends to the tip of the sail board. The duct 7 opens into the upper surface of the sailboard and forms a recess 8 which accommodates a spring clamp 9. The rubber spring is connected to the spring clamp by a flexible connecting member 10. Inside the recess 8,
Said spring tightener can be adjusted in the longitudinal direction of the sailboard 2 along a rail (not shown). By adjusting, the initial tension of the rubber spring 6 can be varied.

In addition to being securely connected to the sail board 2, the support member 4 is connected to a rubber spring 6 for easy release. Whereas prior art designs ensured a secure connection only when in use, i.e. when the sailor was holding the rigging on the sailboard, the present invention ensures that the rigging is not held in place. When this is not done, for example, when a very large force is acting on the sail and tries to pull it away from the sailboard, which may occur over a wide range, the force overcomes the force of the spring. , a reliable connection will be automatically restored.

The present invention will now be described with reference to FIGS. 2-5, which show a portion of the sailboard 2 having a longitudinal groove 11, and a section of the sailboard 2 having a longitudinal groove 11 therein. A box 12 is slidably attached to the. A claw 1 is attached to one end of the box 12.

It is also located inside the support member 4 and is firmly fixed to the support member 4. The roll 21 is a locking pin 22
is attached to. The support member 4 is arranged in a recess 24 of the carriage 25, said recess also receiving the pedals 18, 18'. The pedals are interconnected by a locking pin 22 which can be resiliently locked within one of the lateral openings 26 of the box 12. The pins 19, 19' attached to the bottom of the pedal and supporting the rolls 20, 20' have extended ends 27, 27' which are connected to the interior of the box 12 by means of transverse grooves 28. It plays the role of guiding the pedal in the longitudinal direction. The pins 19, 19' fit into slots 30, 3 inside the side wall 29 of the receiving part 24.
0' and can therefore be moved laterally within the groove 28. The upper part of each side wall 29 of the receiving part 24 has a substantially triangular hole through which the locking pin 22 extends, so that the sliding part 25
When the locking pin is released, longitudinally displaced and relocked, the locking pin can move in all directions.

The pedals 18, 18' have foot engaging portions 32, 32' which project from the surface of the sailboard and have a constant profile surface 33. Applying vertical pressure to the pedal with your foot and then pushing the pedal sideways releases the slide 25 and
A longitudinal displacement of the entire mast is initiated. At one end of the longitudinal groove 11 formed in the interior of the sail board 2 and receiving the box 12, an inclined surface 34 is formed, which facilitates the removal of sand and other foreign matter. In order to lift the box 12 out of the groove 11, the pawl 13 is provided with a stressing member 35, for example a loop, which resists the force of a compression spring 36.
