Definitions
- the present invention relates to a device for assisting in the learning of a gliding sport on a gliding board, in particular a board, comprising at least one leash having at least one strand with two ends.
- Patent application EP 0 561 125 describes a device making it possible to secure and direct a child when skiing.
- This device mainly consists of a harness which is worn by the child and an endless leash connected to said harness. This leash allows another skier, for example an instructor, to hold the child on the slope and to direct him.
- the object of the invention is to improve the known devices for assisting in the learning of a sliding sport on a sliding board, in particular on a surfboard.
- the present invention more specifically aims to provide a device allowing a beginner to experience his first sensations of sliding in the most realistic way possible, while ensuring it so that he launches on the slope with a minimum restraint and tension.
- the device according to the invention comprises at least one leash with at least one strand having two ends, and is characterized in that the strand is fixed by at least one of its ends to the gliding board, of so that it can be slowed down or guided by means of said strand.
- One of the advantages of the invention is to allow the student to always be placed in the direction of the slope which facilitates the operation of the gliding board.
- the strand may be intended to be held at the other end thereof by a monitor.
- the device comprises two leashes with one strand each, each strand being fixed at one of its ends to the gliding board and intended to be held at the other of its ends by a monitor.
- an additional strand can be attached to each leash at two points, each additional strand being intended to be held approximately in the middle by the user of the gliding board so as to help him to keep its balance.
- the device is characterized in that the fixing of each strand to the gliding board is carried out by means of braking means fixed to a basic element, said means of braking being actuated by said strands of the leash.
- the braking means may comprise a spatula mounted freely in rotation on each side of the base element on an axis fixed to said element by means of a rotating ring, the rotation of the spatulas being controlled by a traction on each of the strands of said leash.
- the rotational travel of the spatulas can also be limited and the strand or strands can be attached to handles to facilitate their maintenance by one user.
- the device comprises two leashes formed by one strand each, the strands of each leash being fixed by their ends to the gliding board and intended to be held by the user of said gliding board.
- the user of the gliding board preferably holds the strands by means of handles.
- Figure 1 is an overall perspective view of two surfers, a student and a monitor, linked by the device according to a first embodiment of one invention.
- Figure 2 is an overall perspective view of two surfers, a student and a monitor, linked by the device according to a second embodiment of one invention.
- Figure 3 is an overall perspective view of a student learning to surf with the device according to a third embodiment of the invention.
- Figure 4 is an overall perspective view of two surfers, a student and a monitor, linked by the device according to a first variant of the second embodiment of the invention.
- Figure 5 is an overall perspective view of two surfers, a student and a monitor, linked by the device according to a second variant of the second embodiment of the invention.
- FIG. 6 is a perspective view of an example of a brake system used in the variant shown in FIG. 5.
- Figures 7 to 10 show in detail the brake system of Figure 6.
- a student 1 on a surf 2 is retained by a monitor 3, himself on a surf 4 by means of a leash having a strand 5.
- This strand is fixed at one of its ends 6 at student 2's surf 2 and held at the other end 7 by the instructor 3.
- This system which is very simple, allows the monitor 3 to easily control the student's speed when he is in line with the student's trajectory. By moving perpendicular to the trajectory of pupil 1, the monitor 3 can also influence the change in trajectory of the pupil, that is to say a turn, in a very simple manner. Beginning pupil 1 is thus very quickly put in confidence and can exercise the movements necessary for learning without being hampered in his movements by a harness, for example.
- the second embodiment of the invention is shown.
- the elements identical to the first embodiment are identified by the same references.
- the device includes in this embodiment two leashes with a strand 5, 8 each, these two strands 5, 8 being fixed at one of their ends 6, 9 to the board 2 of pupil 1, and held by the instructor 3 at the other of their ends 7, 10
- the end 6, 9 of the strands 5, 8 can be fixed approximately in the middle of the gliding board 2, between the bindings, or either on the front thereof or on the rear of the gliding board 2.
- the instructor can thus, by acting on the two strands 5 and 8 at the same time slow down the surf 2 of pupil 1.
- a third embodiment is shown in Figure 3.
- This embodiment includes two leashes with a strand 11, 12 each, each strand 11, 12 being fixed by one of its ends 13, 15 on the front of the surf 2 and by the other of its ends 14, 16 on the rear of the surf 2.
- the surfer 1 can therefore grasp the strands 11, 12 of the leashes.
- This embodiment notably provides a significant aid for keeping the surfer in balance and allows him to move freely, without link with another surfer or skier, such as for example the monitor 3 shown in FIGS. 1 and 2.
- An alternative embodiment consists in combining the second embodiment with the third.
- This variant which is represented in FIG. 4, makes it possible to combine the advantages of the two embodiments, on the one hand by employing a person, such as the instructor 3, to retain the gliding board 2 of the pupil 1, and, on the other hand, by providing pupil 1 with means helping him to keep in balance.
- the position of the fixing of the strands 11, 12 held by the student 1 on the strands 5 and 8 can be moved so as to allow an adjustment to the size of the student.
- the end 6, 9 of the strands 5, 8 can be fixed in the middle of the gliding board 2, between the bindings, or else on the front thereof. or on the back of the sliding board 2.
- the two strands 5, 8 of the leash are not directly attached to the gliding board 2 of student 1, but by means of a brake system 37 which itself is actuated by said strands 5 and 8.
- This brake system 37 can be placed on the rear of the surf 2, or between the bindings of the surf 2 as shown in FIG. 5, or else on the front of the surf 2. An embodiment of the brake system 37 is described in more detail with reference to FIGS. 6 to 10.
- the brake system 37 consists of a base plate 38 pierced with oblong holes 39, 40, 41 which allow it to be mounted on the gliding board 2, for example below one of the fasteners, said oblong holes 39, 40 and 41 being crossed by the screws which make the fastening integral with the gliding board 2.
- a block 42 which supports the various mobile elements of the brake is mounted on this base plate 38.
- the block 42 comprises in particular two lateral faces which are cut so as to form inclined faces 17 and 18 which support the movable elements of the brake.
- This brake which is perfectly symmetrical on each of the faces 17 and 18, mainly consists of the following elements: a support 19, a rotating mobile ring 20 mounted on the support 19, a locking means 21, a brake 22 and a part of connection 23.
- the identical elements of the braking system placed symmetrically on each face 17 and 18 of the block 42 are referenced identically.
- the support 19 is fixed to the block 42 by means of four screws 24 which are screwed into corresponding threads of the block 42.
- the support 19 also comprises an axis 26 pierced with an axial thread 27.
- the axis 26 has a groove 28 extending in the axial direction and starting from the upper edge of the axis 26.
- the ring 20 is described with reference to FIGS. 8 and 9.
- This ring 20 comprises an O-ring part, the central hole 32 of which fits on the axis 27 of the support 19 so that it is movable in rotation once mounted.
- the ring has a lug 33 on its underside which is immersed in the notch 30 of the support 19 so as to effectively limit the rotational travel of the ring 20.
- the ring 20 also has two holes 34, 35 and a groove 36 perpendicular to its longitudinal axis.
- the groove 36 allows the blocking of a helical return spring between the ring 20 and the support 19, the other end of the spring being hooked in the groove 28 of the axis 26 described above.
- the diameter of the central hole 32 can be increased on the lower side of the ring 20, that is to say the side located towards the flange 29 of the support 19 when the ring 20 is mounted in position.
- This housing is indicated in FIG. 9 by the reference 43.
- blocking means 21 are used. These means consist of a part 21 in the form of a disc or washer with a diameter approximately equal to the diameter of the ring 20 and the center of which is pierced with a hole, and a screw 25 which is screwed into the internal thread 27 of the axis 26. The ring 20 is thus maintained on axis 19.
- the guiding and braking means comprise a piece 22 in the shape of a spatula, or of a golf club, the handle of which is fixed in the hole 35 of the ring 20, by screwing or gluing for example.
- This part 22 is intended to be immersed in snow and thus brake or direct the surf.
- the shape of the tip itself can be varied.
- the link between the strands 5, 8 and the brake system is constituted, for example, by an elongated tube-shaped element 23 which is fixed at one of its ends in the hole 34 of the ring 20, by screwing or collage for example.
- the other end of this element 23 is intended to be fixed to one of the strands 5, 8 of the leash thus allowing one actuation of the braking means.
- the device according to the invention is mounted, for example, between the bindings of the gliding board 2 of student 1, and the two people are connected to each other by the leash with two strands 5 and 8.
- These two strands 5 and 8 are each fixed to the tube 23 of each brake 22 and traction on one of the strands 5, 8 causes the rings 20 to rotate forwards, and consequently causes the brakes 22 to plunge into the snow.
- student 1 is slowed down, even guided, while retaining complete freedom of movement at the level of the body, in particular at the level of the shoulders, pelvis and legs.
- the return spring mounted between the ring 20 and the axis 26 the spatulas 22 are brought back permanently to an approximately horizontal position, as soon as the tension on the strands 5, 8 of the leash is released.
- the leash may include simple loops or retractable handles, such as those used in a known manner for dog leashes, for example.
- the handles of the device according to the invention optionally include a spring winding system making it possible to catch the slack in the strands and to be equipped with a locking system making it possible to adjust the length of each strand of the leash 5.
- the attachment between the strands of the leash and the device may be detachable so as to be released in the event of an impact, for example if another person practicing skiing or surfing crosses the two surfers while passing between them. that is to say in the passage blocked by the leash. It is also possible to limit the rotational travel of the braking and guiding means.
- the instructor can himself use a surfboard, skis or other equivalent means to move around.
