Description

The invention relates to a device for individual movement in order to tiansform the pedestrian into a self-supporting walker. This bicycle whose seat height adjustable supports users of all ages owes its inertia to sporadic leg movements according to the desired speed of movement. Footrests for user comfort also serve as luggage racks because: blues and other burdens. The invention recognizes the fact that any burden placed on wheels becomes very easy to move.

If we add to this observation the success of the industry in the field of casters carrying burdens: it is easy to deduce that the bicycle of the invention has excellent mobility. La larche à pieds is excellent whenever it is synonymous with relaxation or walking. Walking on foot raises the problem of hardship whenever it is necessary to rejoin a destination far from a car park, a bus station or SN CF or other place distant from an appointment.

In our modern times, walking is more and more necessary in urban areas, so parking becomes impossible, especially to reach a place of exhibition or simply a business or medical office because in addition it will be necessary to envisage a long time to be on time ... The invention responds to these problems on the basis of a trilogy. The first part lies in the lightness of the invention which leads to a pleasant handling and within the reach of the weakest. To this must be added an attractive production cost in view of the simplicity of the system. The second foundation lies in the fact that once folded the bicycle of the invention 10 is not at all cumbersome because the three tubes that form the chassis are arranged in parallel and do not encumber public transport or in a office or other premises including luggage lockers. The third foundation retains two advantages, the principal of which lies in the comfort level: the invention being endowed with a novel suspension. Among these many advantages advantage that is not negligible is the speed of travel that corresponds without fatigue at the speed of a runner. This invention: a mobile, lightweight, collapsible device, including the U-shaped frame; equipped with two wheels whose standard shape is similar to that of scooters receives a saddle adjustable in height and a steering handlebars often equipped with an inertia brake. Its surprising simplicity leads to an attractive cost. This invention is the ideal means for its convenience and playfulness for individual travel in order to eliminate fatigue and save time. The present invention has another excellent advantage formed by the suspension system. 37 29-9-8537 3 More concretely, an innovative suspension mechanism due to its articulation and the quality of its components. In the first place if a suspension is not required on scooters: 5 a device with wheels made of hard material (of the traditional PVC type) imposes a flexible suspension, otherwise all shocks caused by the rough edges of the road are painfully felt at the saddle. The present invention has diverted this problem. More concretely, the saddle support tube rests on the chassis frame through flexible material components on inking points that form a non-rigid support polygon. In the field of flexible components from rubber and its derivatives known and widespread in the industry in general. The flexibility system of the invention comprises a kind of flexible mattress housed in appropriate housings and traversed by shafts connected to the mechanism carrying the seat tube. Another advantage of the invention is that it folds easily for storage purposes. Concretely the chassis is formed of three tubes which are easily removed to be stored longitudinally to reduce the maximum space. In another application of the application the mobility is made by means of a tricycle. As a result, the device is similar to a tri-carrier. This tri-carrier comes serve people with reduced mobility and takes the form of a walker the user is self-supporting.

In another application of the invention the tricycle, takes the form of a burden door for use in any field at the example of a golfer. Indeed the front handlebar receives a door burden, likely to receive many items including all the equipment of a golfer. In this application of the invention the wheels are compatible with an evolution in any terrain because the device is advantageously motorized on the rear wheel.

In this application of the invention the base of the U which is that of the bicycle, this base whose end is articulated in the steering column, this end this lodge in a carrier axle of two wheels is surmounted by a steering column finished with a handlebar.

In one of the applications of the invention for information and non-limiting is in Figure 1: the object of the invention and presented in profile. The marks (1) and (3) form the wheels of the device.

These wheels are connected by an arm (4) whose end is articulated on a hinge (11). Mark (5) is the steering column surmounted by the handlebar (6) In FIG. 2: the object of the invention is formed by a tricycle by the marks (19) (20) and (3) forms the lifting triangle this scooter with wheels whose diameter and shape remain compatible with the use of this device. 8-537 5 The mark (21) forms the handlebars that hold a reference multipurpose load carrier (22). The arm (4) is often identical in all applications. This is made possible by the simple fact that it has longitudinal blades locked between them not buffers. One end of this articulating arm (4) articulates on the handlebar (21). In Figure 3 the reference (5) is the steering column which overcomes the wheel (1). The hinge (11) forms a hinge in which the end of the arm (4) is articulated. This hinge (11) receives a removable pivot which allows on the one hand the rotation of the steering column under mechanically favorable conditions. This hinge (11) receives a pivot which when removed allows to separate the steering column of the frame (4). Figure 4: The marker (25) receives a hinge (16) provided with a flexible rubber traversed by a shaft. Figure 5: A second elastic reference device (15) is located under the arm (25) to be housed between the longitudinal blades for the arm (4). This assembly forms a novel suspension device, since it receives in its application, different elastic device from the helical spring or blades, or other device capable of performing the function of elasticity claimed by the weight of the saddle.

Figure 6: the device receives a motor formed by an electric accumulator (23) connected by wire to a motor (24) connected to the wheel (3). The device (29) is the remote control or radio control.

This radio control device or remote control can be installed on the footrest (28). This repdse foot or foot (28) also receive a mechanical control for inertia brake. More concretely in Figure 1, the mark (8) is the seat carrier tube. The marker (10) supports this set.

The reference mark (2) is the support tube of the steering column and integral with the hinge (11). In FIG. 2 the reference mark (28) is the foot block which in certain applications receives the inertia brake device formed by a lever and a longitudinal piston that will lock the wheel. This footrest receives the remote control in its electric motor version. In Figure 4 the arm (4) receives the device (14) and (13) which are the elements intended to orient in the hinge (11) with its removable pivot.

In Figure 7 the device of the invention is moved, (3) and (1) are the wheels retained by the arm (4). (9) is the support tube of the saddle mark (4), the mark (6) is the handlebar.

In Figure 5; the mark (26) is the plate secured to the base of the arm (24) and intended to support the base of the elastic component (15) or similar material for operating a suspensjon. In the field of applications of the invention: the plate (26) is fixed over the entire length of the arm to form a U for strength. The suspension is obtained by the oscillation of the device (26) integral with the tube (6) and which is articulated on the bearing (16) This bearing (16) receives a compatible elastic component which is traversed by a shaft (30) fixed on blades forming the arm (24) In one of the applications of the invention and in Figures: 1 and 6; a pressure inertia brake exerted on a pedal having a return spring, moves a drawbar equipped with a pad which compresses the rear wheel with each pressure exerted on this pedal A in Figure 1; (31) is the brake pedal which is articulated on an axis (32) provided with a return spring. The rod (33) is provided with a bearing in which articulates the drawbar (34) This geometric assembly forms an obtuse angle with the brake pedal. The drawbar (34) is articulated at the other end on a link mechanism (36), one end of which receives the brake pad. This inertia brake mechanism is advantageously streamlined inside the arm (34)
