and in particular, a guide piece 20, which comprises the base 10, and which is in relation with said fork 30.

The cohesion of the entire device 1 is ensured by the connection of the parts 10, 20, 50 by an axis 4 which passes through orifices 1 1, 21, 51.

The base 10 is for example a U-shaped rectangular part. The bottom of the base 10, called the apron 13, may comprise perforations 16, located along lateral uprights 12a and 12b along a line 15. The base 10 is secured to the upper part of the end of the gliding board 100, part called heel, by screw, glue or any other appropriate means. It is made of any suitable material, for example thermoplastic.

The base 10 is integral with the gliding board 100. It is the part that joins the other elements of the device 1.

In its front part, two orifices 1 1 on the lateral uprights 12a allow the base 10 to be secured via the axis 4 and through the orifices 51 and 21, on the one hand and on the outside of the base 10, to the protective cover 50, and, on the other hand and inside the base 10, to the telescopic bearing assembly, consisting of the guide piece 20, the telescopic fork 30, and the element rolling 48. The front end of the deck 13d forms an arc serving as a housing for a spring 5 and the axis 4 which passes through the spring 5. The end 6 of the spring 5 fits into a notch 14 of the deck 13.

The base 10 is divided into two parts. The front portion 10a, consisting of a front apron 13a and front uprights 12a, and the rear portion 10b consists of a rear apron 13b and rear uprights 12b.

The notch 17 in the apron 13 marks the separation of the two front portions 10a and 10b rear and allows the bending of the base 10, allowing him to marry different heel curves of the gliding board along their longitudinal axis.

The apron 13 of the base 10 has in its underside 13 'from the lines 15 of the thinned edges 13c in the form of chamfers.

The amounts 12a comprise at their ends one or more notches 18 in correlation with teeth 54a of bolts 54 of the protective cover 50.

The base 10 is positioned on the upper part of the gliding board so that the rolling element 48 is located in the off position on the end of the heel of the gliding board inside the cover 50. (see Fig. 6 and 7), and in service position beyond the heel of the gliding board out of the cover 50 (see Fig. 8 and 9).

The guide piece 20 is of rectangular shape and profiled U. It serves as a support for the telescopic fork 30 which fits into its uprights 22. The guide piece 20 is embedded in the base 10 and connected thereto by the axis 4 through the orifices 21 of the uprights 22. This assembly allows the guide member 20 the rotational movements about the axis 4, allowing the telescopic fork 30 and the rolling element 48 to take the necessary inclinations in the service and out of service positions, regardless of the longitudinal curve of the heel of the gliding board.

The lateral uprights 22 of the guide piece 20 comprise grooves 23 able to receive ribs 33 of the telescopic fork 30.

A rib 24 located in the longitudinal axis of the part 20, is composed of two flexible and retractable tongues 25 detached from the apron 28.

The ends of the tongues 25 are provided with lugs 26.

These lugs 26 serve to position at the end of travel the telescopic fork 30 in the guide piece 20. The lugs 26 may be of various shapes, for example of triangular shape.

The telescopic fork 30 is the support of the rolling element 48.

The lateral uprights 32 of the front portion 36 each comprise a rib 33, configured to cooperate with the lateral grooves 23 of the guide piece 20 for allow sliding of the telescopic fork 30 in the guide piece 20.

At the end 36a of the front portion 36, in the longitudinal axis, a stop 35, whose longitudinal profile may be of various shapes (arc, triangle, trapezoid or for example in the form of a semicircle), and an aperture 34 arranged just behind, have the function of receiving and pushing a rib 56 of the protective cover 50 with each translational movement of the telescopic fork 30.

In the front portion 36 of the fork 30 a recess 36c which may be of various shapes, cylindrical for example, makes it possible to receive a hook 55 of the protective cover 50.

A recess 36d makes it possible to receive the end of the branch 7 of the spring 5.

The rear portion 37 of the telescopic fork 30 comprises two branches 38 each having an orifice 31. The ends 38b of the branches 38 have thicknesses substantially greater than the roots 38a, the branches 38 flaring on their outer faces 39. The outer faces 39 may be of concave or any shape, partially or completely striated.

The branches 38 of the rear portion 37 of the telescopic fork 30 receive the rolling element 48 via an axis 44 disposed through the orifices 31.

Fig. 4 represents the underside 30 'of the telescopic fork 30.

A recess 42 at its center in the longitudinal axis allows the engagement of the rib 24 of the guide piece 20.

In the recess 42 are the notches 43 and 45 designed to receive the lugs 26 of the tongues 25 of the guide piece 20.

The location of the notches 43 and 45 corresponds to the limit switches of the telescopic fork 30. The notch 43 receives the lugs 26 in the service position, the telescopic fork 30 being fully extended.

The notch 45 receives the lugs 26 in the off position, the telescopic fork 30 being completely folded.

The interlocking of the lugs 26 in the notches 43 and 45 is intended to retain and / or maintain the telescopic fork 30 in the service and out of service positions.

The rolling element 48 may be made of an elastic material. It is cylindrical in shape. It can be a cylinder drilled in its center, it can also be the juxtaposition of several wheels of the same or different thicknesses. The axis 44 passes through the orifices 31 of the branches 38 of the rear portion 37 of the telescopic fork 30 and allows the rotational movement of the rolling element 48.

The axis 44 can be blocked on the orifices 31 of the branches 38 of the rear part 37 by riveting or by tightening screws or nuts on the ends of the axis 44 previously threaded or threaded.

The parallelepipedal or trapezoidal protective cover 50 (FIG 5) covers the base 10 and the telescopic bearing assembly 20, 30, 48.

The ends 52b of lateral uprights 52 have notches 52e whose outer faces comprise chamfers 52c, which facilitates the gripping of the rolling element 48.

The upper part 50s of the cover 50 may be carved with geometric or heterogeneous shapes or have a more or less flat surface with asperities of various shapes or ribs omnidirectional orientations.

The lid 50 is connected to the base 10 by the axis 4 which passes through the orifices 51 of its lateral uprights 52 and rings 53.

This arrangement allows the protective cover 50 to rotate the necessary movements, to release or enclose the rolling element 48.

The end 7 of the spring 5 fits into the hook 55 which may be of various shapes or tubular for example.

The function of the spring 5 is to fold down the protective cover 50 on the telescopic bearing assembly. By the tension it exerts on the protective cover 50, it keeps the telescopic bearing assembly 20, 30, 48 against the heel of the gliding board, regardless of its position in space. A light 52a on each upright 52 allows pushers 58 located outside the protective cover 50 to cause the bolts 54 located therein in a longitudinal movement allowing the teeth 54a of the bolts 54 to engage with each other. notches 18 of the uprights 12a of the base 10, thus ensuring the locking of the protective cover 50 on the base 10.

Inside the protective cover 50 the rib 56 positioned in the longitudinal direction, is housed in the opening 34 of the telescopic fork 30 when the latter is folded in the off position.

The setting in service position of the device 1 is effected by a single gesture of the hand, by maneuvering, towards the rear of the gliding board, the bolts 54 of the protective cover 50 and the telescopic fork 30, by pressing on pushers 58, then on the outer faces 39 of the branches 38 using for example thumb and forefinger.

The pushers 58 withdrawn towards the rear of the gliding board, allow the teeth 54a of the bolt 54 to be released from the notches 18, unlocking the protective cover 50 of the base 10.

In the translational movement of the telescopic fork 30, during its deployment, the stop 35 by its side 35a exerts a pressure on the side 56a of the rib 56 of the protective cover 50 raising it. The end wall 57 of the protective cover 50 is then raised, releasing the passage to the rolling element 48.

The telescopic fork 30 fully extended, the spring 5 exerts a tension on the protective cover 50 via the hook 55, on the parts 35a and 36b of the telescopic fork 30 by the parts 56b and 57 of the protective cover 50 and contributes to maintaining the telescopic fork 30 in its service position.

The setting in off position is by the support of the rolling element 48 on the ground, the gliding board in vertical position.

The rolling element 48 is pushed into its housing, the telescopic fork 30 rising vertically in the guide piece 20.

The side 35a of the abutment 35 raises the rib 56 of the protective cover 50 by the part 56b, raising the end wall 57 of the protective cover 50 to the passage of the rolling element 48. The stop 35 having passed the median axis of the rib 56, under the effect of the spring 5, the side 56a of the rib 56 exerts a pressure on the side 35b of the stop 35 and pushes the telescopic fork 30 at the end of the race. , completely closing the protective cover 50 and thus contributing to maintaining the telescopic fork 30 in the off position.

In fact, said complementary retaining member 701 equips a proximal end of the guide piece 80 and / or the base 10, namely an end intended to be positioned near the end (rear edge) of the gliding board 100. As for the complementary holding member 71 1, the latter equips a distal end of the guide piece 80 and / or the base 10, namely an end intended to be positioned at a distance from the end (rear edge) of the gliding board 100.

According to a particular embodiment, said retaining member 700 and said holding member 710 are combined and constituted by one and the same retractable tongue 290 as mentioned above.

The device 1 comprises at least one means 72 preventing the pad 2 from disassociating from the base 10, in the off position and / or in the operating position. The pad 2 can thus remain associated with the gliding board 100 during its use of gliding or during transport or storage. The user no longer needs to remove the pad at the risk of losing it.

In fact, this means 72 preventing said shoe 2 from dissociating (in the operating position) from said base 10 comprises, on the one hand, an abutment 720 equipping the shoe 2, more particularly the guided part 81 of the sliding mounting means 8 that comprises this pad 2 and, on the other hand, a bearing surface 721 which cooperates with said stop 720 and which comprises the base 10, more particularly the guide piece 80 of the sliding mounting means 8 that includes this base 10.

In addition, this means 72 preventing said shoe 2 from being disassociated (in the off position) from said base 10 comprises, on the one hand, a stop 722 fitted to the shoe 2, more particularly to the guided part 81 of the sliding mounting means 8 that comprises this pad 2 and, on the other hand, a bearing surface 723 which cooperates with said stop 720 and that comprises the base 10, more particularly the guide piece 80 of the sliding mounting means 8 that includes this base 10

The device 1 comprises, again, at least one securing means in displacement for securing in motion the pad 2 and the base 10, more particularly between the service and out of service positions of the pad 2 and in translation in the service-out-of-service directions. and vice versa. These securing means advantageously make it possible to hold the pad 2 and the base 10 firmly together, despite the displacement of said shoe 2 with respect to said base 10, more particularly in a direction perpendicular to the direction of movement of said shoe 2.

Such a securing means comprises, on the one hand, ribs 292, respectively grooves 293, that comprises the pad 2 (more particularly the pusher block 29 and / or the guided part 81 of this pad 2) and, on the other hand on the other hand, grooves 801, respectively ribs 802, which comprises the base 10 (more particularly the rail 800 of the guide piece 80) and which cooperate with said ribs of the pad 2.

Finally, the invention relates to an assembly 1000 constituted by a gliding board 100 as mentioned above and by the towing device 1 (having the characteristics described above).

The advantage of the present invention lies in particular in that it advantageously simplifies the use of the towing device of the gliding board in all situations, sliding, towing and storage to keep the towing means secured to the gliding board.

Another obvious advantage of the invention is the ability of the user to perform a simple hand movement commissioning, respectively, disabling the device by exerting a force greater than the force of stress means in the service position, respectively holding means in the off position.
