Definitions
- the present invention relates to a crutch device for stabilizing a vehicle comprising at least two in-line wheels, in particular a bicycle.
- the term "two-wheelers" will be used hereinafter to designate such a vehicle, without this being limiting, the invention being particularly applicable to vehicles comprising more than two in-line wheels.
- the object of the invention is in particular to provide a device allowing two-wheeled pilots to stop without having to put the foot or feet on the ground, to maintain balance, intervening before the complete stop of the vehicle. It is also to propose a device allowing to have a central crutch on wheels, usable in particular when the user of the vehicle is not on the vehicle, for example when it moves next to its two-wheelers. holding it in his hand.
- such a device must advantageously be put into service, when the user moves, without the hands leaving the handlebars, which can be dangerous, because likely to cause imbalance and / or uncontrolled change of direction .
- the two-wheeler is a bicycle, otherwise called a bicycle, that the commissioning of such a device can be done without the feet of the cyclist leaving the pedals, especially to maintain all motor skills , so the balance.
- a crutch device for a two-wheeled vehicle, comprises at least one crutch arm movable in rotation and a retractable lug fixed at least indirectly to the crutch arm, said crutch device being designed to be mounted on the crutch.
- Such a device advantageously comprises control means.
- control means may comprise a lever, which may be a brake type lever, fixed on the handlebar and connected by a cable to the pin, so that an action on the lever causes the pin in its active position, against the action of return means for the lug, said biasing means being provided to bias the lug to its retracted position when no action is exerted on said control lever.
- the control means may also include a handle rigidly connected to the crutch arm and extending substantially upwards, to be accessible to the hand of a user of the two-wheelers. The use of lever control on the handlebar thus activates the lug without the user removing a hand from the handlebars or a foot of a pedal.
- the use of the handle allows to set up the device, especially when the user is not on the two-wheel, so do not use the pedal.
- Such a device may also comprise holding means for the stand arm in its upper position.
- These holding means may comprise a holding spring intended to be fixed on the one hand to the arm, and on the other hand to the chassis of said two-wheelers.
- These holding means may also comprise a high elastic clip, that is to say intended to hold in the high position, provided to be fixed to the frame of said two-wheel and to engage at least indirectly with the arm. If the device comprises each holding means, when the arm is engaged with the high clamp, the high position is a fully raised position for the arm, and in that when the arm is only held by the holding spring, the high position is an intermediate position.
- the spring therefore does not constitute a return means strictly speaking for the stand device, but mainly a holding means when the device has been urged towards its upper position by the friction of the rollers on the ground or by the action of the arm pedal on the spur.
- the handle can be used for move from the intermediate high position to the fully raised position in the high clamp, and thus finalize the lifting of the device.
- the high clamp notably makes it possible to avoid movements of the stand device, for example in response to irregularities in the ground traveled.
- the device can be sold separately from the two-wheelers, with mounting means, to be mounted on a two-wheeled vehicle.
- the invention also relates to a two-wheeled vehicle equipped with such a crutch device, original or not.
- FIG. 1 is a schematic representation, in elevation and side view of a bicycle equipped with a stand device according to the invention, the device being shown in a high position;
- FIG. 2 is a schematic representation, in elevation and side view of the bicycle of Figure 1, the device being shown in a low position;
- FIG. 3 is a schematic partial view, in perspective, of the device of FIGS. 1 and 2;
- FIGS. 4 and 5 are schematic representations of the operation of the pin, respectively shown in a retracted position and in an active position;
- FIG. 1 represents a bicycle 1 equipped with a device 2 according to the invention.
- the device is attached to a rear fork 3 of the bicycle 1, which extends substantially from the axis X4 of the crankset 4 to the axis X5 of the rear wheel 5.
- the device 2 comprises a hinge 6 forming a pivot 6 about a crutch axis X6 parallel to the crank axis X4.
- the articulation is disposed immediately under the fork 3 and at the rear of the bottom bracket X4. It can be fixed by welding under the fork, especially if the device is originally mounted on the bike. In the example particularly illustrated in FIG. 3, the articulation is fixed by means of a counterplate 7.
- the device 2 further comprises two leg arms 8 which extend from the hinge 6, on either side of a median plane P of the bicycle 1, but inside the paths of the arms 9 of the crankset 4. Thus, during the pedaling action, the crank arms move in rotation on either side of the crutch arms.
- the device also comprises, at one end of each crutch arm, a remote end of the hinge 6, a wheel 10.
- the median plane is a plane parallel to the plane of FIG. 1, and substantially forming a plane of symmetry for the frame of the bike.
- the device 2 further comprises a handle 11, rigidly connected to the stand arms. The handle 11 extending substantially parallel to the median plane, in a direction substantially opposite that of the crutch arms.
- the device 2 also comprises a traction spring 24 hooked on the one hand to one of the stand legs 8, and on the other hand to the fork 3, close to the wheel axle X5, so that it biases the stand legs 8 in their high position PH illustrated in FIG.
- the device 2 more particularly comprises an elongated lug 12 (see in particular FIGS. 4 and 5).
- This lug 12 is slidably mounted on a lug support 13.
- the support 13 is rigidly connected to the skewer arms, so that it moves in rotation around the skewer axis X6, at the same time as the lug arms. stand 8.
- the lug is provided to move in its support 13, substantially transversely relative to the median plane P, two opposite walls 14,15 of the support 13 together forming a bearing for the lug 12.
- the lug is formed of one piece with a flange 16, disposed between the two walls 14,15.
- a coil spring 17 is mounted around the lug, prestressed between a first 14 of the walls of the support 13 and the collar 16, so that it solicits the flange 16 towards the second wall 15.
- the flange 16 also serves as a fastening at one end of a sheathed cable 18, of the bicycle brake cable type, the other end of the cable 18 being connected, as schematically represented in FIG. Figure 2, a lever 19, also of the type used for bike feins.
- the cable is mounted such that an action on the lever stretches the cable so that the lug 12 moves against the action of the spring 17, by compressing it.
- an active end 20 of the lug 12 extends through the first wall 14, so that the active end 20 comes to intercept the trajectory of the bottom bracket 9, as particularly shown in Figure 5.
- the lug When no bias is exerted on the lever 19, the lug is in a retracted position illustrated in Figure 4.
- the bottom bracket 8 illustrated in FIG. 6 comprises a cam 22 which extends along the path of the bottom bracket shaft, in the direction R of the back pedaling.
- This cam 22 makes it possible to anticipate the contact of the bottom bracket arm and the active end 20 of the lug 12, so that when the device is put in place, and especially when crossing the vertical V, the foot 23 of the cyclist has a substantially upward movement, so to develop more power, so to put in place more easily the device 2.
- Two solutions can be used to reduce the crutch arm from their low position to their up position.
- a first solution one can put the lug in its active position, by the same action on the lever 19, and pedal in the direction N, normal for the advancement of the bicycle and reverse the direction of coaster R. Then the arm pedal 8 comes into contact from the front with the active end 20 of the lug 12, and drives the device 2 to its high position PH.
- the use of the lug 12 to bring the arms 8 in their upper position allows to generate by pedaling a sufficient effort to allow snapping.
- the second solution is to leave the lug in its retracted position of Figure 4.
- the friction forces of the soil on the wheels are such that the arms are solicited and then driven beyond the vertical V. Then, their movement continues to a high position under the action of the spring 24.
- the spring 24 is essentially a holding spring of the device in this intermediate position. The spring is provided not to oppose too much effort when setting up the device. Consequently, it is sufficient to lift the device but it does not allow snapping with the high clip 25. This snap can be obtained as previously, by placing the pin in its active position, or by using the sleeve 11.
- the handle 11 may be used more particularly when the rider is not on his bike, he can use the interaction of the pin and the pedal to move the device 2 between its high and low positions.
- the two arms are held together, in particular to prevent their spacing under the weight of the cyclist by a spacer 26.
- This spacer has a U-shape, each of the arms is connected with a respective crutch arm. It is arranged so that in the high position PH illustrated in Figure 3, it provides a passage for the wheel 5, while allowing a position of the wheels on either side of the wheel.
- the wheels even if they are particularly spaced apart, do not present discomfort for the cyclist, particularly when the bike is tilted or when it runs along an obstacle like a sidewalk.
- Such an arrangement is particularly advantageous, especially since a greater spacing of the wheels allows greater stability of the bike when the device is in its low position.
- the lug rather than moving in translation, can also be designed to move in rotation.
- a device according to the invention may not have a handle.
- the high clamp may also be arranged differently, to allow the snapping of another mobile part of the stand device.
- the high clamp is also not necessary.
- the holding spring may be sufficient to ensure complete lifting of the stand device, and to keep it immobilized against a stop. It is not necessary for the operation of the device that the low position is beyond the vertical relative to the high position. It is then advantageous to provide a retaining device, to prevent the arms being biased towards the high position by the spring or friction on the ground.
- These retaining means may have the form of a low elastic clamp, that is to say which is intended to keep the device in the low position.
- the low elastic clamp can be attached to the chassis of the two wheels and at least indirectly engage with the crutch arm, when the arm is in its low position.
- the bass clip can be designed to oppose the force of the holding spring, and, during the advancement of the two-wheel, to a certain friction force beyond which the device is released from the grip of the low clamp and returned to a position by the holding spring.
- the lever will be arranged on the same handle of the bicycle, in opposition to a brake lever, so that the lever 19 can be actuated by the thumb, while the brake lever is simultaneously actuated by the other fingers of the bicycle. the same hand.
- a two-wheeled vehicle equipped with a device according to the invention can be used as a two-wheeled vehicle of the prior art, if the user does not wish to benefit from the advantages of the stand device.
