SKIS THAT CAN BE CONNECTED TO EACH OTHER PERMANENTLY OR TEMPORARILY BY ONE OR MORE CONNECTING ARMS, IN ORDER TO CLOSER, PREFERABLY, TO THE MONOSKI TECHNIQUE.

Abstract

Une nouvelle méthode d'exploitation des skis de neige ou de mer, permettant notamment de skier de façon indifférente soit en biski disjoint, soit en biski joint mobile, ou encore en biski joint immobile. Le nouveau type de biski "polyvalent" est remarquable en ce qu'il est constitué de préférence en avant et en arrière des fixations, d'un système de rapprochement des deux skis composé de deux ossatures (1 et 2), supportant l'un le point d'attache sous forme d'une tourelle (101) ayant un système de blocage permettant de solidariser la tourelle (101) de l'ossature (2) et un téton (103) permettant de fixer un bras de liaison (4) fixé sur l'ossature (1). Ce système de rapprochement des skis sera donc constitué, de préférence, de 3 parties: * le point d'attache (3) * le bras de liaison (4) * le point d'accrochage sur une tourelle (101) autoblocante. L'addition trouve une application principale dans le ski, elle apporte triple choix avec un seul type da matériel: * biski joint mobile, * biski joint immobile, * biski disjoint.

Description

The present addition relates to a ski linking device comprising, in accordance with claim 1 of the main patent, for the practice of, in particular, alpine, touring, cross-country, water skiing and the like, two frames intended to be fixed each to one of the skis and a removable linking arm fixed relative to at least one of the frames and allowing, when in place, a rigid link between the two frames so as to connect, or to contribute to connecting, the two skis rigidly linked to each other in a monoski, the linking arm being able to also be connected to the two frames in a pivoting manner allowing certain relative movements between the two skis. The purpose of this addition is to propose a particularly advantageous structure for the selective connection of the two skis, which can be either a pivoting connection between the connecting arm and the frames, or on the contrary a rigid connection to form a monoski type assembly. According to this addition, the ski linkage device is characterized in that it comprises a turret mounted pivotally on one of the frames, means for removably fixing the ends of the linkage arm to the turret, and means for selectively blocking the rotation of the turret relative to the frame. Thus, a pivoting connection is established between the turret and the frame. This connection is permanent and can be of high quality, particularly robust and relatively insensitive to contact with elements such as snow for skiing or seawater for waterskiing. Removable connections are then limited to locking mechanisms: locking the connecting arm relative to the turret when the two skis are to be joined, and locking the turret relative to the corresponding frame when a rigid connection between the two skis is desired. Preferably, the means for removably attaching the link arm to the turret include a stud with an enlarged head on the turret, and a lateral notch on the link arm, the notch receiving the stud under the enlarged head of the latter when the link arm is attached to the turret, the link arm having a latch selectively closing the entry of the notch so as to lock the stud in the notch. It is advantageous that the means for removably fixing the link arm to the turret include, on the turret, two rims between which the link arm is positioned and prevented from rotating relative to the turret when fixed to the turret. These two edges contribute to the rigidity of the connection between the two skis when the turret itself is immobilized relative to the frame. Advantageously, a drawer is mounted to slide on the turret in a direction parallel to the longitudinal direction of the arm when the arm is fixed to the turret, this drawer being movable by sliding between an open position in which it allows the connecting arm to be associated and dissociated relative to the turret, and a closed position in which, when said end of the arm is fixed to the turret, the drawer covers this end of the connecting arm. This drawer protects the linking mechanisms between the arm, the turret and the frame, and contributes to the aesthetics of the entire device. The means for selectively blocking the rotation of the turret may include a pin that can slide within the turret between a position in which one end of the pin can move freely relative to the frame when the turret rotates, and a recessed position in which said end is engaged in a corresponding recess in the frame and locks the turret relative to the frame. Preferably, the pin can rotate within the turret between a position in which an offset of the pin is located opposite a corresponding region of the frame and allows the pin to penetrate into a recess in the frame and thus lock the turret relative to the frame, and a position in which said offset is angularly offset from the corresponding region of the frame and prevents the pin from penetrating the recess in the frame. In this second position, the pin cannot penetrate the recess even if during the rotation of the turret relative to the frame the pin passes in view of the recess in the frame during the use of the skis with a mobile connection between them. It is advantageous for the connecting arm to be pivotally attached at its other end directly to the other frame, and for this connection to be permanently fixed under normal use. The other frame advantageously includes means for removably retaining the connecting arm in a resting angular position when the two skis are separated. This prevents the connecting arm from being lost. Other features and advantages of this addition will become clearer from the description below. The attached drawings are given as non-liability examples. - Figure 1 is a top view of the device when the two skis are rigidly connected to each other, with the drawer in the open position. - Figure 2 is a view analogous to the bottom of Figure 1, with the drawer in the closed position - Figure 3 is a view analogous to Figure 1, but where the two skis are connected in a movable way relative to each other. - Figure 4 is a view of the device when the connecting arm is in the rest position - Figure 5 is a longitudinal cross-sectional view of the device when the turret is free to rotate relative to its frame. - Figure 6 is a view analogous to Figure 5, but when the turret is fixed in rotation relative to its frame; and - Figure 7 is a cross-sectional view along VII-VII of Figure 6. - Figure 8 is a top view of the locking system in the locked position according to variant 1. Proposing, for example, to create a ski-bringing system conforming to a preferred embodiment of the addition, it will include a pivoting turret (101) of rectangular shape with a major longitudinal axis, preferably perpendicular to the skis. This turret (101) supporting a stud (102) which will serve as a fixing for the connecting arm (4). X a pin (107) allowing the turret (101) to be in either a locked position or a position of free rotation. This pin (107) is in the form of a solid cylinder supporting a protrusion that will serve as a stop in the self-locking position of the system. t a connecting arm (4) having at its proximal end an axis on the frame (1) and at its distal end a locking system securing the arm to the turret (101). Advantageously, the end of the connecting arm will encircle, by means of a ring, the stud (102) which is itself fixed to the turret (101). This ring can be opened by a sliding latch (104) which will automatically return to the closed position by a spring (111). The opening of this ring will occur against the resistance of the spring (111). * a pin (107) will allow (by its constitution) the turret (101) either to follow the movements of the rotating arm, or to secure the turret (101) to the frame (2) and thus to lock the connecting arm. w a drawer (106) which can be opened laterally or as described previously, or in the manner of a lid attached to the turret (101) on one of its longitudinal sides by a hinge and the other opposite side sliding onto the drawer (106) by a rail fitted on the lid and a recess (108) on the lateral side of the turret (101). According to one variant, a system can, of course, be designed to secure the turret (101) to the frame (2) in a different and as simple a way as possible, minimizing handling for the skier, especially since manual actions are not very easy during skiing (for example, due to gloves). This variant has the advantage of allowing the stationary biski joint to be adjusted to a mobile biski joint with a single movement of the ski pole. This new system results in a turret (101) that is shorter in width to provide space for a clip (112) attached to the frame (2) along the longitudinal axis of the turret (101). On the supero-external part of the turret (101) a sliding panel (113) will be arranged intended to enter the clip (112) in the locking position of the turret (101) and so as not to block it the sliding panel (113) will not protrude longitudinally from the turret (101). The clip (112) attached to the frame will of course be sufficiently far from the turret (101) so as not to hinder the rotational movements of the latter in the rest position.
