Definitions
- the present invention applies to those carts whose frame has two front idle wheels and two fixed motorized rear wheels, so that they have a single direction of advance and a single center of rotation when stopped, where a driver located behind the cart grabs a handlebar to make it turn.
- said cart comprises, articulated behind the cart, a rolling platform with two wheels of fixed geometry, thus configuring a motorized articulated vehicle.
- the driver rides on the rolling platform that is separated from the car.
- the articulation between the car and the rolling platform allows the vehicle to be folded so that it can be used in pedestrian mode with electric assistance to facilitate pushing.
- the present invention involves an optimization of a vehicle comprising a cart with a frame having two front idle wheels, two fixed motorized rear wheels - so that they have a single direction of advance and a single center of rotation when stopped - and a fixed handlebar set back from the motorized wheels; and also comprising a rolling platform having a tread area and two wheels of fixed geometry, which is positioned behind the cart to which it is attached by means of a combined joint; said platform can be used either unfolded, rolling on the ground to transport the driver, or retracted, to allow pedestrian use of the cart.
- said combined joint has two and a half degrees of freedom, one in yaw, which allows turning when driving it; another also in pitch, which on the one hand allows changes in level and going up and down curbs, and on the other hand lifting the platform until it is collected under the handlebars in a stable position; and finally it has an extra degree of freedom by deformation, necessarily restricted to allow a certain movement, mainly elastic, of relative rolling between both main elements of the vehicle, that is, a certain torsion that allows absorbing both asymmetrical irregularities of the terrain and any change of level undertaken obliquely, but in such a way that said torsion generates a force opposite to the relative rolling movement between the car and the rolling platform, thus contributing to an anti-rollover support.
- This restricted degree of freedom will preferably be formed by a silentblock-type flexible joint.
- the rigidity of this flexible joint contributes to the stability of the vehicle in curves for use in road traffic, since it allows the weight of the driver on the rolling platform to contribute to the anti-rollover support of the cart, normally loaded, in curves.
- the use of two idle wheels at the front of the cart, one on each side, is equally important.
- Handlebar height [1050,1250]; it must be necessary and sufficient so that the handlebar grip is comfortable both when walking and when riding on the rolling platform.
- Handlebar setback [220,270]; long enough to walk behind the cart without kicking or stepping on it, and to accommodate the folded dolly under the handlebars without disturbing the driver, and short enough so that when turning in road traffic mode, the handlebars do not move significantly to the opposite side, forcing the driver to reach to the outside of the turn and being adversely affected by the centrifugal force involved.
- Width of the tread area on the platform [410,450]; so that the legs are not too close together as this would be detrimental to stability, but there is enough space to accommodate suitable wheels and their corresponding brake systems, and all this without exceeding the total width of the cart.
- FIG-1 shows a front perspective view of a mixed-use motorized articulated vehicle for road and pedestrian traffic; comprising a delivery cart (1) and a folding dolly (2). This figure represents said motorized articulated vehicle in the deployed platform configuration.
- Fig-2 shows a rear perspective view of the mixed-use motorized articulated vehicle for road and pedestrian traffic corresponding to Fig-1. On it, the area corresponding to the combined articulation between the cart and the platform is marked as detail A.
- FIG-3 corresponds to said detail A in enlarged view.
- FIG-4A and FIG-4B show side views of the mixed-use motorized articulated vehicle for road and pedestrian traffic of FIG-1 in its two corresponding states of use.
- FIG-5A and FIG-5B show two plan views of the FIG-1 mixed-use motorized articulated vehicle for road and pedestrian traffic in its two corresponding states of use, the first corresponds to its straight driving, and the second shows a high degree of yaw on the rolling platform, as would correspond to a tight turn.
- a motorized articulated vehicle for mixed use for road and pedestrian traffic is proposed, preferably for delivery and last mile tasks.
- the present invention involves an optimization of a vehicle comprising a cart (1) whose frame has two front idle wheels (121, 122), two fixed motorized rear wheels (111, 112) - so that they have a single direction of advance and a single center of rotation when stopped - and a fixed handlebar (13) set back with respect to the motorized wheels (111, 112); and also comprises a rolling platform (2) that has a tread area (FPP) and two wheels (201, 202) of fixed geometry, positioned behind the cart (1) to which it is attached by means of a combined joint (3).
- Said rolling platform (2) can be used unfolded, rolling on the ground to transporting a driver, or collected in a stable position and secured by fixing means (321) to allow pedestrian use of the vehicle.
- Said fixing means (321) are located below the handlebar of the cart (1) at a sufficient distance to prevent the driver from having to bend down or exert significant effort in the operation of ensuring use in pedestrian mode, when the rolling platform (2) adopts its stowed position.
- said fixing means (321) are made up of a simple plate that is manually pivoted laterally.
- Said combined joint (3) presents freedom of turn in pitch (according to axis A3Y) by means of a transverse pivot axis (JY), which on the one hand allows the vehicle to cope with changes in level and go up and down curbs, and on the other hand to raise the rolling platform (2) to collect it under the handlebar (13) until reaching a stable position, forward with respect to said axis (A3Y) so as not to fall due to its weight; in addition, linked to the transverse pivot axis (JY), it has a vertical pivot axis (JZ) that allows turns to be made when driving it in road traffic mode, which gives it a degree of freedom of yaw (according to axis A3Z); and furthermore, linked to the vertical pivot axis (JZ) it has a deformable element (JX) of the silentblock type that allows a certain swing between the carriage (1) and the rolling platform (2), that is, a certain torsion according to the advance axis (AX3) of the rolling platform (2), which allows to
- the main measurements with a margin of ⁇ 5% are:
- hinges may be embodied by flexible joints... also the size, shape, location or orientation of the various components may be varied. Components shown directly connected or in contact with each other may have intermediate structures arranged between them. The functions of one element may be performed by two, and vice versa. Therefore, the scope of the invention should not be limited by the specific embodiment described, but by the appended claims.
