Definitions

• the present invention relates first of all to a locomotion handlebar provided with a support and guide member of which the handlebar is pivotally integral, the handlebar extending substantially perpendicular to the vertical plane of said member and being provided with its ends of two handles for guiding and pivoting about an axis extending in said vertical plane.
• the field of the invention relates very generally to locomotion vehicles, with motor or pedals, on the ground or on water, and possibly even also in the air, equipped, at the front or, more rarely , at the rear, of a support and / or rolling and guiding member.
• a handlebar which, as its name suggests, serves to guide, or orient, the wheel or the guide pad, of which it is pivotally integral, and is extends substantially perpendicular to the vertical plane of the wheel or the guide shoe.
• the handlebars take the name of the handle but perform a similar function, both for flight and on the ground.
• the invention relates more particularly to handlebars.
• a handlebar is an elongated piece provided at its two ends with two handles on which a driver places his two hands to rotate the handlebar in one direction or the other, around a substantially vertical axis, and drive the wheel with him. , the (airplane) wheel or the guide shoe in a similar pivoting.
• the action of a driver on a handlebar is roughly exerted by deformation of an articulated assembly comprising, in addition to the handlebars, the arms and forearms of the driver, which can be vaguely compared to an articulated parallelogram. .
• the handlebars are no longer only used as a guide. It is used as a means of anchoring the hands to exert a pulling force on the arms, therefore on the body and legs, and thus increase the force exerted on the crankset, when it is a cycle. with pedals. But in this case, the action of the cyclist is no longer exercised, as previously mentioned, by deformation of the articulated imitation parallelogram, but by simultaneously bending the two arms and forearm in two planes. substantially perpendicular. It can therefore be seen that the almost horizontal application of the palms of the hands to the two horizontal handles of the handlebars is not the best position for producing this tensile force and that a vertical arrangement of the palms of the hand is much preferable.
• Handlebar end caps have already been proposed attached to the two ends of a handlebar, extending in substantially vertical planes and allowing cyclists to grip them with the vertical palms of the hand and thus exert maximum effort.
• An airplane handle is also provided with such tips since it is often necessary to "pull" on this handle.
• the present invention relates to a handlebar of a locomotion machine provided with a support and guide member of which the handlebar is pivotally integral, the handlebar extending substantially perpendicular to the vertical plane of said member and being provided with its two ends of two handles for guiding and pivoting about an axis extending in said vertical plane, characterized in that at each guide handle is articulated a pull handle pivotally mounted between a retracted and folded position on the guide handle and a deployed position substantially perpendicular to the guide handle.
• each pair of associated guide and traction handles is one that the driver uses as a guide handle, while in the deployed state , the driver can grasp each pull handle in a natural hand position, palms facing one another, and thus develop the maximum effort, the transition from one state to another can also be carried out both stopped and running.
• the possibility thus offered, of alternating the positions of the handles has the advantage of often necessary relaxation.
• means are provided for locking the pull handles in the deployed position.
• the guide and traction handles are shaped so that, in the retracted position of the traction handles, these match the guide handles to which they are respectively articulated and that at the ends of the handlebars are formed two double guide handles .
• the handlebars are mounted pivoting about a substantially vertical axis, the machine to be guided preferably being a velocipede.
• the invention also relates to a set of two articulated handles for a locomotion handlebar provided with a support and guide member of which the handlebar is pivotally integral, the handlebar extending substantially perpendicular to the vertical plane of said member, one of the two handles being intended to be mounted at one end of the handlebar, for guiding and pivoting about an axis extending in said vertical plane, the other of the two handles, for traction, being intended to pivot between a retracted and folded position on the guide handle and a deployed position substantially perpendicular to the handle guide.
• Figure 1 is an exploded perspective view of the right end of a velocipede handlebar according to the invention
• Figure 2 is an exploded perspective view of the two guide and traction handles of the right end of the handlebar of Figure 1;
• FIG. 3 is a perspective view of the handlebars of the invention, the two pull handles in the retracted position and
• Figure 4 is a perspective view of the handlebar of the invention, the two pull handles in the deployed position.
• the handlebars which will now be described, by way of example only, are those of a velocipede. comprising a front rolling and guide wheel extending, with reference to FIGS. 3 and 4, in a vertical plane 1.
• the handlebar comprises an elongated tube 2 secured, by means of a steering stem of the front wheel, the joining considered here being a joining in pivoting around the axis 3 of the stem extending in the plane 1 substantially vertically.
• the tube 2, here slightly curved towards the rear, generally extends substantially perpendicular to the plane 1 and is provided, at its two ends 4, 5, with two guide handles and right and left pivoting 6,7.
• a lower sleeve element 8 is slid by one end 16 into the tube 4 of the handlebars.
• On the other end 17 of the element 8 is slipped, by one end 18, a lower tubular shell 9 on which is threaded a flexible gripping sleeve 10, the lower shell 9 and the flexible sleeve 10 forming the guide handle 6
• In the other end 19 of the lower shell 9 is slipped one end 20 of a lower hinge part 11 to which is articulated, by a pin 22, an upper hinge part 12.
• This upper hinge part 12 is extended by an end 21 on which is slid an upper tubular shell 13 on which is threaded another flexible gripping sleeve 14, the upper shell 13 and the flexible sleeve 14 forming a pull handle 15. If the sections of the tube 2 and of the end 16 of the sleeve element 8 are circular, that of the end 17 of this element 8, of the lower shell 9 and of the end 20 of the lower hinge part day 11 - 7 -
• the lower shell 9 is fixed to the sleeve element 8 and the hinge part 11 by clamps or screws, like the upper shell 13 on the hinge part 12. Naturally, the relative angular position of the lower shell 9 and the tube handlebar 4 can be modified according to the desired deployed position of the pull handle 15.
• the pull handle 15 is therefore pivotally mounted on the guide handle 6 between a retracted position ( Figure 3), in which it is folded over the guide handle 6, and a deployed position (Figure 4), in which it extends substantially perpendicular to the guide handle 6.
• the pull handle 15 can be locked in the deployed position.
• a lateral boss is formed on one of the hinge parts in order, in the deployed position, to co-operate forcefully with a corresponding lateral recess formed on the other hinge part.
• a lower boss 24 is provided under the upper shell 13 to provide, in the folded position, a space between the two upper and traction 15 and lower and guide 6 handles and thus be able to grip the traction handle 15 and tilt it into position. deployed until the hinge part - 8 -
• the lower tubular shell 9 is slightly flattened, with a substantially elliptical cross section.
• the upper tubular shell 13 is also flattened, but with a substantially annular cross section, complementary to that of the lower shell so that, in the retracted position, reached after having tilted the pull handle 15 against the force of cooperation bosses and recess for locking the hinge parts, the shapes of the two shells fit together and that, still in this folded position, the two guide handles 6 and traction 15 form a single double guide handle that a conductor cyclist can grasp globally with one hand.
