Description

TROLLEY FOR TRANSPORTING AT LEAST ONE PERSON, AT LEAST ONE TYPE OF CYCLE OR AT LEAST ONE WHEELCHAIR FOR A PERSON WITH DISABILITIES, AND OBJECTS

The present invention relates to a device that can be towed by human force, or connected to a bicycle or a controlled device, and intended to carry one or two bicycles of the bicycle or scooter type and their user. The present invention is also intended to carry objects.

The device according to the invention is also intended to transport other wheeled vehicles such as folded wheelchairs for disabled people, and to transport said disabled persons installed on the device outside of their wheelchair. The device is also intended to carry an unfolded wheelchair for a disabled person and its user installed in said wheelchair.

The device is also intended to carry a folded wheelchair of a disabled person and a bicycle type bike or scooter type and their user.

In the state of the prior art, there are known devices for transporting objects in the form of a plate equipped with wheels cooperating with the ground and provided with a rigidly fixed arm, allowing a person to move the device. by human force. Thus, the device moves relative to the ground and pivots along the axis of the wheels.

These devices do not allow selectively transporting wheeled vehicles such as bicycles, wheelchairs for the disabled, or the user or users of said wheeled vehicles.

Devices are also known that can be towed and moved by a bicycle. In this case, the traction arm is arranged to be connected to a bicycle.

There are also devices for towing at the back of a bicycle a single bike via a mechanism establishing an articulated connection between the front wheel of a bicycle and the rear part of a bicycle. In general, this mechanism is fixed on the axis of the hub of the rear wheel of the bicycle. Nevertheless, the towed bicycle is connected to the ground by the rear wheel and is pitched on the rear wheel. Thus, the user of the towed bicycle is not installed in the normal position of piloting and pedaling. These devices are generally unstable. Finally, such devices do not guarantee the safety of the towed person, because they do not prohibit the towed person to leave the towed bike in the driving phase. In addition, in the case where the towed bicycle is a rolling vehicle equipped with rear stabilizers, it is necessary either to disassemble said stabilizers or to modify the position of said stabilizers so as to prevent said stabilizers from being in contact with the ground. . These devices are not suitable for carrying two bicycles, or a scooter, or a wheelchair.

Devices are also known provided with two wheels and connected to a controlled device intended to transport one or two persons in a seated position. These devices do not allow to transport at the same time means of locomotion such as, for example, bikes or scooters used by the person or persons transported.

Also known are devices in the form of a seat, fixed on a bicycle, either at the front or at the rear, or at the front and rear of the bicycle, for carrying one or two passengers. Not all bikes can receive these devices. These devices do not allow to transport at the same time means of locomotion such as, for example, bikes or scooters used by the person or persons transported which is a disadvantage.

There are known devices (document FR-A-2666557) of the trailer type intended to be towed by a bicycle. These devices comprise a frame that can receive two wheels fixed either on the edges of the frame corresponding to the longer sides of said frame, or on the edges of the frame corresponding to the shorter sides of said frame. A crate for transporting objects is fixed to the frame according to several mounting possibilities, depending on the side of the body resting on said frame and depending on the positioning of the two wheels relative to the frame. These devices do not allow to carry a passenger, or wheelchair for disabled person.

For the following description, a direction of movement Ox is defined in which the devices according to the invention which will be described are towed or pushed. The devices can move in the direction of the positive values of the movement direction Ox or in the negative direction. In addition, a transverse direction Oy, substantially perpendicular to the direction Ox, and a direction Oz such that the directions Ox, Oy, Oz define an orthonormal coordinate system are defined. Referring to Figure 1, there is described a device according to a first embodiment of the invention.

The device comprises a chassis 1-2 configured to carry two bicycles 1010, 1012 and objects 1013, two sets 650 of passenger transport seats installed one behind the other, two main wheels 4 and a swivel wheel 5 fixed to rotation on the chassis 1 -2 and for stabilizing the device, a drawbar 6 connected to the chassis 1 -2 and intended to be connected to a person towing the device, and two floors 630 placed on the chassis 1 -2.

The device of Figure 1 is intended to advance in the direction of the positive values of the movement direction Ox, that is to say that the Ox axis points towards the front of the device. The axis Oy points to the left of the device, when one moves in the direction of its movement.

Referring to Figures 1 to 3, the frame 1 -2 extends in the direction of movement Ox with a first extension L1 and in the transverse direction Oy with a second extension L2 (Figure 2).

In the plane (xOy), substantially parallel to the ground, the chassis 1 -2 advantageously has a general shape of rectangular parallelepiped. The chassis 1 -2 has a surface substantially equal to L1 x L2, available for transporting the two bicycles 1010, 1012, the two sets 650 of seats and the objects 1013.

The chassis 1 -2 comprises a first part 1 forming the rear of the chassis 1 -2 and a second part 2 forming the front of the chassis 1 -2.

In Figure 2, the first part 1 is located at the rear of a plane P substantially perpendicular to the movement direction Ox. The first part 1 has in the transverse direction Oy an extension equal to the second extension L2.

According to the movement direction Ox, the first part 1 has a smaller extension than the first extension L1. The first part 1 contributes to part of the extension L1 of the chassis 1 -2 according to the movement direction Ox.

The first part 1 of the chassis 1 -2 comprises a left rear part 200 and a right rear part 500 both comprising metal tubes or composite materials.

The second part 2 is located in front of the plane P. The second part 2 has in the transverse direction Oy an extension equal to the second extension L2. The second part 2 has in the direction of movement Ox an extension less than the first extension L1. The second part 2 contributes to part of the extension L1 of the chassis 1 -2 according to the movement direction Ox.

The second part 2 comprises a left front part 300 and a right front part 400 both comprising metal tubes or composite materials.

The left rear portion 200 of the chassis 1-2 comprises tubes 203, 206, 207 extending substantially in the transverse direction Oy, and tubes 201, 202, 204, 205 extending substantially in the direction of movement Ox.

The rear right portion 500 of the frame 1 -2 comprises tubes 501, 502 extending substantially in the direction of movement Ox and tubes 503, 504 bent, extending substantially in the direction of movement Ox and substantially in the transverse direction Oy.

The right rear portion 500 further comprises a tube 505 extending substantially in the transverse direction Oy.

The left front portion 300 comprises tubes 304, 305 bent, extending substantially in the direction of movement Ox and substantially in the transverse direction Oy, and a tube 302 extending substantially in the direction of movement Ox.

The right front portion 400 comprises tubes 404, 405 extending substantially in the transverse direction Oy, and tubes 401, 402, 403 extending substantially in the direction of movement Ox.

The tubes 404, 405, 203, 206, 207 cooperate by sliding connection respectively with the tubes 304, 305, 505, 503, 504 substantially in the transverse direction Oy.

Thus, thanks to these connections of sliding of a part of the tubes of the frame 1 -

2, the second extension L2 of the frame 1 -2 is continuously modifiable between a maximum value L21 and a minimum value L22.

According to a particular embodiment L22 is about half of L21. For example, L21 is about 1.40 m and L22 is about 0.70 m.

The tubes 302, 304, 305, 401, 402, 403 cooperate by sliding connection respectively with the tubes 202, 204, 205, 501, 502, 503 substantially in the direction of movement Ox.

Thus, thanks to these sliding links of a portion of the tubes of the frame 1 - 2, the first extension L1 of the frame 1 -2 is continuously modifiable between a maximum value L1 1 and a minimum value L12.

According to a particular embodiment L12 is about half of L1 1. For example, L1 1 is about 2.5 m and L12 is about 1.25 m.

In Figure 2, the chassis 1-2 is in a position where the first extension L1 is at the maximum value L1 1 and the second extension L2 is at the maximum value L21.

In Figure 3, the chassis 1-2 is in a folded position where the first extension L1 is at the minimum value L12 and the second extension L2 is at the minimum value L22.

The main wheels 4 and the swivel wheel 5 allow the chassis 1 -2 to roll on the ground.

The device further comprises mechanically welded quick connections 605 to 620 (Figure 2) for connecting one or the other of its ends drawbar 6 (Figure 1) to the chassis 1 -2.

Advantageously, the first part 1 has mechanically welded supports 208, 209, 210 and 506, 507, 508 (Figure 2) for fixing the two sets of seats 650 (Figure 1).

The swivel wheel 5 is fixed on the first part 1 by a bearing support 602. The swivel wheel 5 pivots about an axis Δ substantially parallel to the direction Oz.

Due to the structure of the bearing support 602, the swivel wheel 5 is an idle wheel, that is to say it can rotate 360 ° about the axis Δ. According to a variant, the bearing support 602 is shaped such that the swivel wheel 5 pivots on a smaller angular sector.

According to another variant, the swivel wheel 5 can be fixed on the second part 2. The bearing support 602 is then slidably mounted, for example, on the tubes 404, 405 of the front right part 400.

The bearing support 602 includes a portion 701 attached to the frame 1-2, and a pivoting portion 702 connected by a 360 degree pivot connection to the portion 701.

Part 701 is for example made using metal tubes or composite materials.

The pivoting portion 702 comprises a cylindrical housing so as to be able to rotate the pivoting wheel 5 in a fast and removable manner.

Part 701 also comprises metal or composite tubes cooperating by sliding connection with constituent tubes 503, 504 of the rear right part 500 of chassis 1 -2.

Thus, thanks to these connections by sliding, the swivel wheel 5 can be continuously positioned on the frame 1 -2 in the transverse direction Oy. Bearing supports 603, 604 comprise cylindrical housings so as to be able to rotate the main wheels 4 in a fast and removable manner.

Thus, thanks to these different housings, the main wheels 4 can be positioned either vis-a-vis the bearing support 604, as shown in FIG. 5, or individually on each of the bearing supports 603, 604 as shown in FIG. Figures 2 and 3.

The bearing supports 603, 604 also comprise metal or composite tubes cooperating by sliding connection with the tubes 201, 205, 503, 504 of the part 1.

Thus, thanks to these connections by sliding, the main wheels 4 can be continuously positioned on the first part 1 according to the movement direction Ox.

Two mechanically welded wheel half-supports 621, 622 are slidably mounted respectively along the tubes 502, 504. Advantageously, these half-supports 621, 622 are easily dismountable from the chassis 1-2.

A not shown locking system makes it possible to hold the two half-supports 621, 622 in position. These half-supports 621, 622 make it possible to position and hold the wheel of a cycle-type machine while adapting, thanks to the adjustable possible to the dimensions of the wheel.

Two mechanically welded half-supports 623, 624 are slidably mounted respectively along the tubes 201, 204.

Advantageously, these half-supports 623, 624 are easily removable chassis 1 -2.

A not shown locking system makes it possible to hold the two half-supports 623, 624 in position. These half-supports 623, 624 make it possible to position and hold the wheel 1015 of the bicycle 1010 while adapting, thanks to the possible adjustment, to the dimensions of the wheel 1015 (Figure 1).

The sets of seats 650 (Figure 1) are positioned one behind the other in the movement direction Ox and clipped into four locking devices 640 fixed on the first part 1.

Two floors 630 are installed on part 1 (Figures 1 and 4). The floors 630 can transport any objects, such as objects 1013, whose size and weight allow them to be placed and transported by the device.

Referring to Figure 4, there is described a device according to the invention, configured for the installation of a wheelchair for disabled person and its user (not shown). With respect to the frame 1-2 of Figures 1 to 3, the second portion 2, removable, has been removed.

The left front part 300 and the right front part 400 (not shown) have been disassembled and separated from the frame 1 -2. Thus, an opening is made possible in the chassis 1 -2, allowing a wheelchair and its user to be installed on the device by means of two access ramps 1014.

The two floors 630 easily removable are placed on the first part 1 of the chassis 1 -2, which can carry objects whose size and weight are compatible with the device. It is thus possible to transport objects, passengers or a wheelchair independently for a disabled person and his user.

Once the disabled wheelchair installed, the front left 300 and front right 400 can be reassembled to ensure the maintenance on the chassis 1-2 of the objects carried by the device.

To facilitate the placement of the wheelchair on the device, the access ramps 1014 are hung on the portion 1 of the frame removably and adjustable manner in separation and inclination relative to the ground.

Each access ramp 1014 comprises an access rail 1004 and a stand 1000 whose one end has a groove for positioning the tubes 505 or 203 and whose other end is provided with pivoting pads 1003 intended to bear on the ground .

A mechanically welded means 1001 tilting makes it possible to fix each access ramp 1014 on the tubes 505, 203.

Each access rail 1004 is mounted by pivot connection on the extension 1002 of one end of the stand 1000.

With the access rail 1004, the access ramps 1014 can be connected to the frame 1 -2 of the device so as to provide the necessary stability during the installation of the wheelchair for a disabled person and its user on the device according to the invention.

Advantageously, during the rolling phase of the device, the access ramps 1014 provided with their crutches 1000 take place inside the frame 1 - 2.

Referring to Figure 5, there is described a device according to the invention in a storage position. The device of Figure 5 differs from that of Figure 3 only in that: - The chassis 1 -2 is oriented so that the transverse direction Oy is pointing upwards, that is to say that the chassis 1 -2 has rotated a quarter turn in the direction of movement Ox,

the main wheels 4 are mounted on either side of the frame 1 -2 in the direction of substantially horizontal direction Oz,

- The bearing support 602 of the swivel wheel 5 is set in a configuration in which the swivel wheel 5 pivots about an axis Δ ', substantially parallel to the transverse direction Oy.

We will now describe the operation of the device. To load a wheelchair, the device is mounted in the configuration shown in Figure 4. With the access ramps 1014, the wheelchair can be placed on the floors 630.

Objects 1013 can also be placed on floors 630.

Then the second part 2 is eventually raised.

The drawbar 6 is fixed on one or the other of the extreme sides of the frame 1 -2, on the welded quick connections 605 to 620 (Figure 2).

Then the drawbar 6 is connected to a belt 1050 (Figure 1) or a harness carried by a person who will tow the device in the direction of the positive values of the movement direction Ox.

Alternatively, instead of a wheelchair, sets 650 sets of seats.

Two bicycles 1010, 1012 can also be transported, their rear wheels being received in wheel supports formed by the half-supports 621, 622, 623, 624 and the tubes 201, 204, 502, 504.

After use, the device can be disassembled into pieces with a mass of less than 10 kg or stored (Figure 5).

With the features described above, we obtain a device that can transport, individually or combined, at least one passenger, at least one wheelchair or at least one cycle, and objects. The chassis 1 -2 has dimensions that can be adjusted according to the movement direction Ox and / or the transverse direction Oy. The device is thus more compact and therefore easy to use.

The device provides a set of benefits that no device known to date is able to offer.

The device can conform to occupy a minimum restricted volume to be stored, such as in the trunk of a motorized vehicle trunk. The device can be modified in size to adapt to the types and number of objects it must carry and also to adapt to the number of passengers it must carry.

A second embodiment of the invention will now be described with reference to FIGS. 6 to 8.

The second embodiment is distinguished in particular from the first embodiment by the shape of the first portion 1 and the second portion 2 of the frame 1 -2 (Figure 6).

The device shown in Figure 6 is intended to flow in the direction of the negative values of the movement direction Ox.

The first part 1 and the second part 2 are interconnected by a hinge 3 extending substantially in the transverse direction Oy.

The swivel wheel 5 is mounted on the second part 2 of the chassis 1 -2.

The first part 1 of the frame comprises sections 25, 26, 29, 30 extending substantially in the direction of movement Ox.

These sections 25, 26, 29, 30 may be made of metal material, such as steel or aluminum alloy. They can also be manufactured in whole or in part of non-metallic material to reduce weight while ensuring the robustness of the frame. The profiles 25, 26, 29, 30 are mechanically welded to two angles 33, 35 to form a main structure of the first part 1.

The profiles 25, 26, 29, 30, which will also be called "slides", are substantially parallel to each other. Their inner profiles receive ends of the cross members 70, 73, 13, 14, 74, 77, 15, 16 extending substantially in the transverse direction Oy.

Each end of the crosspieces 70, 73, 13, 14, 74, 77, 15, 16 is provided with an extension capable of sliding freely along the inner profile of the profiles 25, 26, 29, 30. The extension may advantageously be made from a roller or a material component capable of sliding freely along said inner profiles.

The profiles 29, 30 form the central part of the first part 1 of the frame 1 -2 and are mounted back-to-back so that their respective internal profiles are substantially symmetrical with respect to the common joint plane (xOz) of said profiles .

The inner profiles of the slideways 25, 29 thus form two substantially parallel translational guide rails of the crosspieces 13, 14, 70, 73. The inner profiles of the slideways 26 and 30 thus form two substantially parallel translational guide rails of the crosspieces 15, 16, 74, 77.

Two half-wheel supports 17, 19 are slidably mounted substantially in the transverse direction Oy respectively along the crosspieces 13 and 14. The assembly 13-14-17-19 constitutes a first right front wheel support.

Advantageously, the assembly 13-14-17-19 is easily removable from said frame 1 -2.

The half-supports 17, 19 are U-shaped and can slide into one another. A not shown locking system makes it possible to maintain in relative position the two half-wheel supports 17, 19.

Thus, in the assembled position, the two half-supports 17, 19 form an annular receptacle whose length is adjustable due to the sliding of the cross members 13, 14 in the direction of movement Ox.

This annular receptacle is intended to receive, position and maintain the wheel 100 of a machine of the cycle type 1012 (Figure 6) or disabled wheelchair, while adapting, thanks to the possible adjustable length of the annular profile, to the dimensions of the wheel.

The sliding of the half-supports 17, 19 along the crosspieces 13, 14 in the transverse direction Oy also makes it possible to position the annular receptacle in an adjustable manner between the two slides 25, 29.

Two half wheel supports 71, 72 are slidably mounted respectively along the cross members 70 and 73. The assembly 70-71 -72-73 constitutes a second right front wheel support.

Advantageously, the subassembly 70-71 -72-73 is easily removable from the frame 1 -2. It is structurally similar to the 13-14-17-19 set and works in a similar way.

Two half wheel supports 18, 20 are slidably mounted respectively along the cross members 15, 16. The assembly 15-16-18-20 constitutes a first left front wheel support, similar to the assembly 13-14. 17-19.

Two half wheel supports 75, 76 are slidably mounted respectively along the cross members 74 and 77. The assembly 74-75-76-77 constitutes a second left front wheel support, similar to the assembly 13-14. 17-19.

The second portion 2 of the frame 1 -2 comprises profiles 27, 28, 31, 32 extending substantially in the direction of movement Ox. The profiles 27, 28, 31, 32 are mechanically welded to two brackets 34 and 36 to form a main structure of the second part 2 of the frame.

The profiles 27, 28, 31, 32, which will also be called "slides", are substantially parallel to each other and their inner profile is intended to receive the end of sleepers 21 to 24 extending substantially in the transverse direction Oy .

Each end of the crosspieces 21 to 24 is provided with an extension capable of sliding freely along the inner profile of the slideways 27, 28, 31, 32. The extension may advantageously be made from a roller or roller. a material component capable of sliding freely along said inner profiles.

The profiles 31 and 32 form the central portion of the second portion 2 of the frame 1 -2 and are mounted back-to-back so that their respective internal profiles are symmetrical with respect to the common plane of assembly (xOz) of said profiles.
