Definitions

• the present invention aims to allow the realization of a simple and reliable attachment to be able to tow vehicles or rolling object safely thanks to the already existing installations in the mountains, during periods outside snow.
• the fastener according to the invention is particularly intended to use in summer the ski lifts or other ski lift in the mountains and to develop summer leisure activities in the mountains.
• the invention relates to a fastener with manual control to allow the transport, in particular by ski-lift rod outside the winter season, of cycles or rolling object and in particular of cycles used for the practice of velocross and mountain biking.
• the fixing under the load prevents imbalance from the start, thus allowing use of this system by all.
• the strap being slightly longer than the towing machine see Figure 4 board 2/8 and being fixed to the seat tube under the chargena towing, there is very great freedom of movement laterally and vertically which allows without difficulty avoiding possible obstacles, stone holes, variations and counter slopes, which is not the case for Patents DEA 1943373 DEA 2334308 FRA 2005450 USA 3942452 FRA 817879.
• the invention is remarkable in that the release of the traction control on the lever (14) either voluntarily or as a result of a fall causes ori fice the unlocking and therefore automatically eliminates the towing which is not the case in the patents: DEA 2334308 FRA 2005456 USA 3942452 FRA 8417879.
• the object of the present invention is to ensure the attachment of the cycles to the cable from the ski lifts while meeting all the conditions set out above.
• this connecting device between a general tractor cable and a cycle applicable in particular to ski lifts to ensure the ascent, outside of the winter season, of cycles and similar machines and in particular of all-terrain cycles used for the practice of velocross and mountain biking.
• the assembly for towing advantageously consists on the one hand of means intended to be secured to the seat post or to the frame under the saddle under the load to be transported to avoid imbalance due to the tractive effort.
• the sheathed cable or strap (16) which serves as a link between the towing cycle and the levers (41,42) of the locking system is fixed to the seatpost (33) or to the frame (25) under the load to be towed.
• the ball (36) olive (39) rings or any other means of connection between the rod (21) and the locking member which can be mounted on a flexible cable (3rd) itself fixed under the rod (21) by l 'via a nut or any other means of connection.
• the towing member (1) may advantageously consist of two levers (41, 42) brought to the gripper-like end of a shape (44) allowing to receive a ball (36) olive (39) rod tube (21) or ring (32) these two levers (42, 41) are joined by an axis (40) allowing the pivoting of a spring (46) fixed between the levers in steel, aluminum, plastic or any other material, molded or not, keeps the end in the shape of a clamp open.
• the cable (12) and its sheath (13) fixed on the lower part of the levers by two holes (43) drilled in them allows thanks to the pressure exerted on the handle (14) to close the levers in the form of pincers on the ball, olive, rings fixed under the cane (21) of the ski lift, the release of the traction control on the lever, either voluntarily or by fall automatically results in unlocking and therefore automatically eliminates towing.
• the cable or strap (16) which connects the machine can receive in parallel an elastic element between two points of the cable more spaced than the length of the relaxed elastic element fig; 6 to allow greater flexibility during departure from the traction passing through the elastic element then after abutment on the strap, direct traction by the cable.
• the towing member may be mounted on a tube or any other telescopic connection means mounted on a shock absorber or any other system capable of providing a more flexible departure with a spring or internal shock absorber interposed allowing the shock of the departure to be absorbed and allowing the automatic retraction of the elements and their attachment to the frame after reassembly, the frame then being provided with means for holding said tube.
• the sheathed cable (16) which serves as a connection between the towing cycle and the plate (1) of the locking system is fixed to the seat post (33) or to the frame (25) under the load to be towed by a clevis (29) disposed at the end of this cable to be secured with a collar (30) fixed on the seat tube (33) or on said frame (25) the element to be fixed to the rod saddle (33) perhaps a drum (28) provided with a return spring provided with a fixing box on the frame (25) of the cycle under the saddle, under the load transported and to which is attached to be rolled up the strap or cable (16) which connects the levers (t) of the attachment system.
• a ring (32) is provided fixed by a collar (10) on the seat post (33) to secure the strap or the cable (16) provided with a fastening element such as: hook, carabiner, chappe with the levers (41,42) of the attachment system.
• ring fig: 8 pincemuni of form (47) allowing the fixing on a tube or directly on the cane (21) of mechanical lift.
• Such an assembly is applicable to the traction of any vehicle or object rolling by ski-lift, the user having to keep tight the control handle (14) of the locking member all the time he wishes to be tampered with.
• the invention is not limited to the embodiment which has just been described, it extends to any assembly consisting on the one hand of a fastening member provided with connecting means at the end of a cane ski lift, on the other hand a towing member provided with locking means of said attachment member controlled by cable from a control member secure to the vehicle to be towed. Said member being connected under the load to be transported by flexible link which can be rolled up or not to the vehicle to be towed.
• the invention also extends) any manufacturing method, for example molding of parts, to the locking of levers controlled electromechanically by a circuit with switch and power supply not illustrated 1.
• Fig: 12 A collar (30) provided with a drum (28) with its spring (34) for fixing and winding of the cable or strap.
• FIG. 13 A collar (30) provided with a ring (32) for fixing under the saddle a cable (16) or strap.
