FR2753429A1 - ARTICULATED DEVICE, TO BE ADAPTED ON BICYCLES ON ALL TERRAIN OR OTHER ROLLING OR SLIDING VEHICLES, FOR THE UPGRADING OF DENIVELEES BY THE USE OF TELESKI OR PERCHE MECHANICAL UPHOLDS - Google Patents

Abstract

The invention relates to a device allowing ski lifts to be operated, without modification of the latter, by users of cycles, and that in all seasons. The arm (1) is fixed on the handlebars of the cycle; the gripping piece (3) and (5), integral with the first by an articulated cylinder (2), surrounds, when in a vertical position, the saddle (8) of the pole of the ski lift (7). The movable part (5) of the gripping piece is brought into a vertical position and remains in this position while keeping the control (not shown) pressed. The harness (8) of the pole (7) of the ski lift is presented in the opening of the gripping part (3) and (5) and is thus kept blocked. The absence of pressure on the control allows the mobile part (5) of the gripping part to be released and, as a result, the harness (8) from the pole (7) of the ski lift either at the end of the route, or in case of imbalance or fall.

BDESCR I PT I ON

  The present invention relates to an articulated device & adapt on so-called all-terrain bicycles, or other rolling or slippery vehicles, to enable the ascent of the elevations to be raised by the use of the mechanical lifts of the type

ski lift or pole.

  The invention allows the use of lift lifts of the ski lift type, by cycle users, in all seasons. The commercial operation of ski lifts not being done

  generally only during the winter for skiers.

  The invention also allows users to perform, without having the technical and physical capabilities, hiking

inaccessible usually.

  The invention makes it possible to open new forms of leisure

in the mountains.

  The invention differs from the patents DE 1 815 531, FR 2 601 637 and FR 2 667 836 in that no modification of the telescopic poles is necessary; that the mechanism object of this patent is totally different as to its principle, (no hooking system is fixed on the pole), as to its presentation, but also as to its use and particularly in terms of stall safety in case accidental fall. The device according to the invention overcomes these drawbacks and thus opens the use of ski lifts by cyclists during all seasons. The device according to the invention is simple to use and

  easy operation while providing increased security.

  The device comprises in its basic principle various elements: an attachment arm of the assembly, an articulated cylinder damping the movements of the pole and a gripping part comprising a fixed part and a movable part which tilts around an axis and who hangs by manipulating a command. One of the elements, the arm, is fixed on the handlebars of the cycle; the other the gripping part, secured to the first by an articulated cylinder, surrounds, when in the vertical position, the fifth wheel of the telescopic boom. The movable part of the gripping piece is brought into vertical position and remains in this position while maintaining the control handle pressed. The fifth wheel of the telescopic boom is presented in the hole of the gripping piece and is thus kept locked. The absence of pressure on the control allows the unlocking of the movable part of the gripping piece and releases, therefore, the fifth wheel of the telescopic boom either in

  end of course, either in case of imbalance or fall.

  According to particular embodiments: - the locking device of the movable part of the gripping piece is actuated by pressing a control located

  on one side or the other of the handlebars, or on the system.

  - The handlebar mounting arm is modified for adaptation to the handlebar support and / or frame depending on the particular technical characteristics of the manufacturers.

cycles.

  - The gripping part engaging in the fifth wheel of the telescopic boom and serving as a point of attachment between the cycle and the pole can be made in the form of figures,

  of various objects or of creative and artistic inspiration.

  - This previous part is modified according to the physical criteria concerning the users (women, children) and the technical criteria concerning the particular shapes of some lifts, in particular those receiving two persons or

  possessing different saddles.

  The attached drawing illustrates the invention:

  FIG. 1 is a sectional view of the invention in its basic version. Referring to FIG. 1, the device comprises an arm (1) fixed to the handlebars and / or to the cycle bracket (not shown), an articulated cylinder (2), a gripping part composed of a fixed part (3) and a movable part (5). The movable part (5) of the gripping piece is locked or unlocked. Blocked by the manual pressure exerted on the control (not shown), unlocked when no pressure is exerted on the same command. Before grasping the telescopic boom (7), the movable part (5) of the gripping piece must be locked in the vertical position by manual pressure on the control (not shown). The user can at this time use this traction means by first presenting the pole (7) between the fixed part (3) and the movable part (5) of the gripping part. The saddle (8) is held by one or more stops (6) inside the orifice, which allows the user to position correctly on his cycle, both hands on the handlebars, before the launch of the lift. The control makes it possible, at the end of the course and by flipping it, to unhook the moving part (5) of the gripping piece which is unlocked and thus releases the boom of the ski lift (7) or the ski lift. The piece (5) used to hold the boom of the ski lift (7) allows by the shape of its orifice and by its operation, to be easily released from the pole (7) by flipping the control (not shown) in case of

  imbalance or fall of the user.

  Referring to this drawing and more particularly to the gripping piece (3) and (5) matching the fifth wheel (8) of the pole (7) of the ski lift, the pieces are not fixed in their shapes and can represent figures, various objects

  existing or of artistic and creative inspiration.

  Similarly, in a variant not shown, to perfect the safety of users, the gripping piece (3) and (5) and the particular design of its axis (4) allow,

  in the event of inadvertent braking, to bring the moving part (5) into a horizontal position and, by this action,

pulling the pole (7).

  According to a variant not illustrated, the release lever of the movable part (5) is located on one side as well as on the other side.

  the other of the system, even on the arm (1).

  Similarly, according to another variant not shown, the fixing system (1) on the handlebar is replaced or supplemented by a fixing on the frame or on the fork because of the criteria.

  particular achievements of certain cycles.

  The device according to the invention is particularly intended to facilitate the ascent of the elevations by the users of bikes off-road using the mechanical uphill slopes

ski lift type.

  The device responds to two requests from the first cyclist always looking for new walking sites and the second from the managers of summer resorts in search of new activities in order to profit commercially structures like ski lifts used only in winter currently. The creation of this new activity through the off-road bike will also make it possible to use all the existing infrastructures currently in the stations and under employed in the summer period. But still, this invention will make it possible to use ski lifts in winter by cyclists who wish to practice hiking
