Description

Multi-use and transportable motorized carrying device

The present invention belongs to the technical field of motorized equipment transporting people and/or objects.

The invention relates more particularly to a versatile motorized carrying device intended to be used in different fields, for different types of use, and having the capacity to be transportable.

The invention finds direct application in sectors requiring support or assistance for the person to limit efforts, such as in the industrial environment, in activities of daily life, or during sporting activities.

State of the art

Carrying devices have been used since the dawn of humanity to transport people, or to help carry objects of varying weight and bulk.

Thus, we find in everyday life examples of the use of platforms, trolleys, and other devices carrying out these actions.

For example, in the industrial environment, and in factories in particular, trolleys are used to transport goods between different workstations.

In general, motorized carrying devices provide various advantages such as reducing the physical effort required to transport heavy or bulky loads, increasing the efficiency of logistics activities because they are faster than manual carrying.

Over time, carrying devices have evolved to become more functional, more comfortable and more aesthetic.

Nowadays, there is a wide variety of trolleys and other carrying devices available to meet the needs of different areas.

Without this representing a limitation, the field of golf is taken here as an example to illustrate a practical use case. Thus, trolleys can be used to transport a golfer's equipment, or even, by means of a golf cart, the golfer, his playing partners and their equipment. In addition, as the practice of golf is becoming more and more democratic and is enjoying great success with the public (notoriety of professional players, reintegration by the International Olympic Committee of the golf event in the Summer Olympic Games since the 2016 edition in Rio de Janeiro, etc.), new trolleys are being developed to meet the new needs of users.

US10016666B2 describes a golf bag cart for transporting a passenger and a golf bag on a golf course. The cart described can be converted from an expanded mode for use to a compact mode for storage. The cart includes various subassemblies (front, steering, bag support, center support, rear drive). The center support subassembly includes running boards for transporting the standing passenger. The cart is propelled by a pair of rear drive wheels each having an associated electric motor controlled by the passenger using a controller. However, the cart described in this document is not capable of transporting multiple golf bags, nor does it incorporate an automatic user tracking function.

The same is true in document EP0602300A1 which describes a motorized golf trolley which allows a golfer and his equipment to be transported. Compared to the trolley described in the previous document, this one seems to have a reduced compactness, but requires disassembly of certain parts to allow its transport in the trunk of a motor vehicle. Furthermore, the trolley described in this document is not capable of transporting several golf bags, nor does it integrate an automatic user tracking function.

CN109388133A describes a golf cart having a smart user tracking function. The smart tracking golf cart mainly comprises a golf cart body and a beacon.

The golf cart body consists of several modules (power, control, driving, motor, guidance, obstacle avoidance).

The beacon is equipped with an ultrasonic transmission module and a manual control module.

By means of a smart tracking device in the golf cart and the tag carried by a user, the golf cart follows the user at their request.

In contrast, document CN109388133A does not describe a cart that can also transport a user, in addition to its intelligent tracking function.

WO2020222329A1 discloses a trolley, usable in golf activities, and having an automatic tracking function, the trolley being equipped with respective components optimized to implement a user tracking function, and mainly comprising a receiving portion for receiving articles, a main body coupled to the lower portion of the receiving portion, a wheel assembly rotatably coupled to the lower portion of the main body for moving the trolley, and a plurality of sensor modules for detecting obstacles and tracking the position of a transmission module.

However, the cart described in this document does not allow a user to be transported and cannot be considered easily transportable.

There do not appear to be any motorized carrying devices that can be used by several users at the same time, that can be controlled manually or automatically, and that once they are finished using them, fold easily and are compact to facilitate their transport (in the trunk of a vehicle, in a box, etc.) as well as their storage.

Presentation of the invention

The present invention aims to overcome all or part of the drawbacks presented above, and thus proposes an innovative solution to facilitate the motorized transport of people and objects.

Advantageously, this solution is modular, versatile and easily transportable, and can be used in different areas (industrial, daily life, sports activities in closed environments as well as outdoors, etc.)

For this purpose, the present invention relates to a multi-use and transportable motorized carrying device for transporting people and objects of one and/or more users, comprising a platform on which are fixed a mast, two footrests, at least one caster positioned at the front of said platform, at least two drive wheels positioned at the rear of said platform, said drive wheels being connected and controlled by a control unit, said mast being fixed to the platform by means of a mast support, said mast comprising at least one object attachment. This device is remarkable in that it is controlled by means of at least one remote control; that a user of said device can be on the platform or outside of said device; and that the mast comprises at least a lower part and an upper part connected by a joint, said mast being foldable when one end of the lower part is outside a housing of a sliding system of said mast; and that the device is transportable without requiring complete or partial disassembly.

According to a particular feature, the device is manually controlled by a user by means of directional, emergency stop, on/off buttons on the remote control.

According to another particular feature, the device is piloted automatically by locating one or more users carrying a remote control.

According to another special feature, the device moves according to a geographic coordinate system.

Advantageously, the drive wheels can be disengaged and/or locked via remote control.

Advantageously, the control unit comprises an electrical energy storage means, a charge and discharge controller, a transmitter/receiver module, a drive wheel control means, a memory, a data processor and a means for transferring incoming and outgoing information.

Advantageously, the platform includes a removable seat that can be adjusted in height.

Advantageously, the transported objects are held in place by means of elastic straps.

According to a particular characteristic, the object attachment comprises a plurality of arms, each of said arms comprising at least one passage hole for inserting the elastic strap.

According to another particular feature, the length of the elastic strap is adjusted by locking by means of a screw on the arm of the object attachment.

Finally, and advantageously, the mast and the platform form a variable angle of inclination between 0 and 180°.

Detailed description of embodiments

It should be noted that certain technical elements well known to those skilled in the art are described herein to avoid any insufficiency or ambiguity in the understanding of the present invention.

In the embodiment described below, reference is made to a motorized, multi-use and transportable carrying device. In order to facilitate the understanding of the present invention, the example of application to the field of golf is given, without this representing a limit, the technical characteristics of the invention adapting and transposing to other fields, without modifications or with modifications that the person skilled in the art has the ability to make.

There represents a carrying device 100 which mainly comprises a platform 10, a mast 11, on which are fixed a plurality of object attachments 12, said mast being connected to said platform by means of a mast support 14, said device being motorized by means of two drive wheels 18g and 18d actuated via a control unit 20, said unit receiving movement instructions from a remote control 17 or ordering automatic tracking of a user carrying said remote control, said device also comprising one or two swivel casters 19.

The platform 10 comprises a handle 101 in order to facilitate the transport by hand, the loading and the unloading of the device 100. Advantageously, and in a mode of use where the drive wheels 18g and 18d are disengaged (in other words, are in freewheel mode ), the device 100 is able to be towed using a tow bar in the handle 101. This tow bar can be a long iron, the head of which is positioned in the handle 101, or any other object having characteristics similar to those of a tow bar and which the person skilled in the art has to his knowledge.

Also, the platform 10 comprises footrests 102, on an upper surface SurfS10 of said platform. The footrests 102 are held on the upper surface SurfS10 by means of screws (not shown here), said footrests being able to be easily removed if necessary that no element is present on said surface (delivery of the device 100, installation of a seat on said device, replacement of the footrests 102, etc.). In addition, the footrests 102 can be adjusted to the shoe sizes of the users.

For example, an internal volume reducer (not shown here), which takes all or part of the shape of the footrests 102, but with reduced dimensions, can be inserted into said footrests to reduce their internal length and/or width.

To stabilize the device 100, and prevent it from tipping backwards, the platform 10 also includes a stabilizing wheel 103.

The platform 10 is preferably made of wood, without this representing a limit to the present invention. In addition, the dimensions of the platform 10 adapt to the use as well as to the need that will be made of it. In particular, the device 10 can be manufactured in different sizes so that said device can be used by adults or by children and is also fully customizable.

In a particular embodiment, a non-slip coating covers all or part of the upper surface SurfS10 of the platform 10.

The mast 11 preferably comprises a lower part 112 and an upper part 111 at the top of which is fixed a handle 13 by means of two screws 131.

Thus, and for a particular embodiment of the invention, the mast 11 can be folded in two, the lower part 112 articulating with the upper part 111 via a joint 16 comprising a pivot connection allowing a rotation of 180° around the axis of said connection. In order to maintain the upper part 111 when the mast 11 is unfolded, the upper part 111 comprises a sliding system 15, which slides along said part, and which allows an end 1122 to be fitted into a housing (not shown here) of said sliding system.

When the end 1122 of the part 112 is embedded in the sliding system 15, the upper part 111 is then constrained and cannot rotate around the pivot connection of the articulation 16, and the mast 11 is then in the unfolded configuration.

The presence of the handle 13 helps in particular a user to stabilize himself when the latter is transported by the device 100 and to manually move the trolley over short distances.

The mast 11 also comprises at least one object attachment 12, fixed by means of screws 123 on the lower part 112 and/or the upper part 111, using holes 1121 and 1111 respectively. Advantageously, the mast 11 comprises a plurality of holes 1111 and 1121 making it possible to adapt the position of the object attachments 12 according to the size of the objects, such as bags for example, to be transported by the device 100.

In addition, the mast 11 is capable of receiving various accessories and other equipment which are specific to the use made of the device 100, by adding additional supports which the person skilled in the art has the capacity to size.

A mast support 14 connects the mast 11 to the platform 10 of the device 100. The mast 11 is held at the mast support 14 by means of at least one clamping knob 141, and the mast support 14 is preferably fixed on the platform 10 by means of screws.

The mast support 14 also has a second functionality which is to be able to tilt the mast 11, both when said mast supports objects, that is to say in the usage configuration, but also with the aim of making the device as compact as possible for transporting and/or storing it.

The angle of inclination of the mast 11 is variable, and is adjusted by means of a wheel 146. Thus, when the device 100 transports objects, the mast 11 can be inclined or not and according to the user's needs, in particular to facilitate, for example, the gripping of golf clubs.

At the base of the mast 11, an object rest 21 is positioned in order to provide additional stability to the objects transported by the device 100, in particular when the mast 11 is inclined.

Preferably, the lower 112 and upper 111 portions of the mast 11 are made of aluminum.

In the embodiment presented in the , the device 100 comprises two drive wheels 18g and 18d, located at the rear of the platform 10, as well as two swivel casters, located at the front of the platform 10.

The 18g and 18d drive wheels each comprise a 181g and 181d wheel consisting of a rolling surface having sufficient grip to drive on hard ground surfaces (tiles, bitumen, etc.) or soft ground surfaces (grass, earth, etc.). The rolling surface of the 181g and 181d wheels may be smooth or have grooves.

The drive wheels 18g and 18d also each include a motor 182g and 182d, operating independently, each of the motors being actuated by the computer device 20.

In the preferred embodiment, the device 100 does not include a steering wheel, and the management of direction changes is carried out directly at the drive wheels 18g and 18d by a difference in rotation speed.

The remote control 17 comprises a housing 171, directional buttons 172a-d, an emergency stop button 173, a locking button 174 of said remote control, an on/off button 175 as well as an operating mode selector 176 (for example automatic tracking or manual piloting).

The speed of movement of the device is variable and can be adjusted, for example, by means of a potentiometer (not shown here), or by successive presses on the front 172a or rear 172c buttons or on a joystick.

In addition, one of the functions of the remote control 17 is to identify one or more users of the device 100, in particular for the automatic tracking mode, and this by means of a sensor (not shown here), ultrasonic acoustic waves or Ultra Wide Band (UWB ) radio waves for example, said sensor being located inside the housing 171.

If the user wishes to be reached by the device 100 in an area where said user is located, a simple press of a dedicated button will launch the instruction command, and the device 100 will then automatically go to meet the user, whose position is located by means of the remote control 17.

In a particular embodiment of the invention, the remote control 17 is a smartphone, connected for example by Bluetooth® to the device 100, and in which an application is installed which reproduces the functionalities of the directional buttons 172a-d, emergency stop 173, locking 174, on/off 175 and the mode selector 176.

In another particular embodiment of the invention, the device 100 is controlled by means of voice commands received by the remote control 17, by a smartphone, or by any other equipment having a similar function and known to those skilled in the art, said commands being transmitted to the control unit 20 of said device.

In another particular embodiment of the invention, the remote control 17 is directly installed on a fixed support, or integrated into the mast, in the form of a control lever ( joystick ).

In another particular embodiment of the invention, the device 100 comprises a plurality of remote controls 17. Each of the remote controls 17 is then distributed to the users of the same device 100. This then allows common and shared use of the device 100 by users who are located in areas that are each far from each other, without however degrading the user experience since it is always possible to have assistance in carrying an object because the device 100 is able to move autonomously between the users who request it. In addition, this promotes and facilitates the transport and transfer of objects from one user to another, as can be imagined and by way of example during common activities, where one or more pieces of equipment are used in turn by the participants.

The control unit 20 is an on-board computer, an automaton, or any other similar equipment known to those skilled in the art, making it possible in particular to control, command and automate the movement functions of said device.

The control unit 20 is positioned on a lower surface SurfI10 of the platform 10.

1. un moderoue libre, c’est-à-dire en débrayant les roues motrices 18g et 18d, et en déplaçant ledit dispositif au moyen de la poignée 13 du mât 11 ou, comme évoqué précédemment, en utilisant une barre de tractage dans la poignée 101 de la plateforme 10 ;
2. un modesuivi automatique, c’est-à-dire en déplaçant ledit dispositif de façon autonome au moyen de la localisation des porteurs des télécommandes 17. Dans ce mode, l’unité de commande 20 est programmée pour que le dispositif 100 conserve une distance de suivi de l’utilisateur qui soit de l’ordre de 1m à 3 m dans le but d’empêcher d’éventuelles collisions. L’arrêt du suivi est ensuite commandé au moyen de la télécommande 17 ou d’un mouvement spécifique de l’utilisateur (pas de recul, etc.). Aussi, et dans une configuration d’utilisation à plusieurs utilisateurs, ledit dispositif rejoint automatiquement l’utilisateur qui en a fait la demande via l’une des télécommandes 17 ;
3. un modepilotage manuel, où ledit dispositif est dirigé par l’utilisateur au moyen de la télécommande ; et enfin
4. un modearrêt, où les roues motrices 18g et 18d sont verrouillées via une des télécommandes par un utilisateur pour empêcher tout déplacement dudit dispositif. Le déverrouillage des roues motrices 18g et 18d par l’utilisateur permet à d’autres utilisateur d’appeler automatiquement le dispositif 100 ou de le piloter manuellement.

Advantageously, the device 100 can be used in four modes of use:

1. a freewheel mode, i.e. by disengaging the drive wheels 18g and 18d, and by moving said device by means of the handle 13 of the mast 11 or, as previously mentioned, by using a tow bar in the handle 101 of the platform 10;
2. an automatic tracking mode, i.e. by moving said device autonomously by means of the location of the carriers of the remote controls 17. In this mode, the control unit 20 is programmed so that the device 100 maintains a tracking distance from the user that is of the order of 1 m to 3 m in order to prevent possible collisions. The stopping of the tracking is then controlled by means of the remote control 17 or by a specific movement of the user (no backing up, etc.). Also, and in a configuration of use with several users, said device automatically joins the user who has requested it via one of the remote controls 17;
3. a manual piloting mode, where said device is directed by the user by means of the remote control; and finally
4. a stop mode, where the drive wheels 18g and 18d are locked via one of the remote controls by a user to prevent any movement of said device. Unlocking the drive wheels 18g and 18d by the user allows other users to automatically call the device 100 or to pilot it manually.

There represents object attachment 12.

In the preferred embodiment, the object attachment 12 comprises four arms 121, each of the arms 121 comprising at least one passage hole 122 for inserting an elastic strap (not shown here). The arms 121 are used in two positions: a folded position, along the mast 11, when the device 100 is transported and/or stored, and an unfolded position, when the device 100 is used to transport objects.

The objects transported by the device 100 are stabilized by the elastic straps which are inserted into the passage holes 122, said straps being held by means of screws 124 which makes it possible to adjust their length, without making knots for example or using any other type of blocking system.

This effective system for stabilizing the objects transported by the device 100 then facilitates their installation and their removal at the level of the mast 11. In addition, the use of elastic straps, and the adjustment of their length, allows the transport of any type of objects, without structurally modifying the mast 11 as well as the object attachments 12. The carrying device 100 is therefore in particular a versatile solution for the transport of objects as well as people, and which is used in different fields, by easily adapting to the volumes, shapes and types of objects to be transported (rigid, semi-rigid, flexible shells, etc.).

In particular embodiments of the invention, the transported objects are held by means of a strap having at least one self-gripping closure system or by means of articulated arms. Advantageously, the object attachment 12 comprises at least two arms 121a which fold by means of an articulation 125, thus facilitating the folding in two of the mast 11.

There represents the object rest 21 which is inserted into the base of the mast 11 by means of an end piece 211.

In the example illustrated here, the object rest 21 comprises two removable wedges 212 on which an object can rest, its base resting on said wedges, thus limiting the risk of the object falling, in particular when the mast 11 is inclined, or if the object requires additional support, in addition to the support provided by the elastic straps.

In other embodiments, the object holder 21 includes an attachment system compatible with containers or objects having, for example, notches provided for this purpose at their base.

This embodiment thus provides additional support for the transport of containers or objects.

Also, the object rest 21 is interchangeable. This means that the same mast 11 is able to receive object rests 21 having wedges 212 of different sizes and shapes, as well as several versions of fasteners.

There represents mast support 14.

The mast support 14 comprises a fixing plate 145 on which the mast 11 is fixed, said plate being integral with a rotation axis 143, said axis being positioned inside an axis support 142, said support preferably being fixed to the platform 10 by means of four screws 1422 passing through holes 1421.

Preferably, the mast 11 is held on the fixing plate 145 by means of two tightening buttons which screw into two tapped holes 1411. Thus, the mast 11 can also be easily separated from the rest of the device 100 if necessary and for transport in particular, or replaced by a mast of a different design (mast with an integrated basket, mast with a footrest, etc.), while retaining the platform 10. In addition, the mast support 14 can also be removed from the platform 10 in order to attach other elements such as a robotic arm facilitating maintenance work, a device for spraying plant protection products. This flexibility with regard to the multiple possible configurations makes the device 100 versatile. This differentiates it, for example, from conventional carts, which are generally single-task, and therefore does not limit the device 100 to a single use (that of transporting golf and golfer equipment, which is described in the application).

Advantageously, the mast 11 has the property of tilting at an angle of inclination α _mast , which can be defined as being the angle formed on the one hand between the upper surface SurfS10 of the platform 10, said surface being represented on the by the Par10 plane, and on the other hand by the fixing plate 145.

The immobilization of the mast 11 at the angle of inclination α _mast , is carried out using dogs 144, locked by means of the tightening button 146.

There , there , there and the represent the carrying device 100 in a folded configuration, respectively in rear perspective view, in side perspective view, in top view and in bottom view. As mentioned above, the device 100 also has the advantage of being easily transportable. For this, the mast 11 folds around the articulation 16, and once the end 1122 of the part 112 is no longer embedded in a housing 151 of the sliding system 15.

In addition, the mast 11 thus folded tilts on the platform 10, around the mast support 14. The device 100 in the folded configuration is thus compact, which facilitates its transport and storage.

There shows a side view of the device 100 in this folded configuration, where the mast 11 folded in two is clearly visible and is tilted onto the platform 10.

The elastic straps used to hold objects on the mast 11 are used in this configuration to hold the device 100 in the folded configuration.

In another embodiment, the mast 11 folds in three or four in order to minimize the volume occupied by the device 100 in the folded configuration. Also, the mast 11 easily detaches from the platform 10 by unscrewing the tightening knobs 141.

There and the represent the carrying device 100 carrying a golf bag 300 installed on the mast 11.

In the , the mast 11 is positioned such that the angle α _mast is substantially equal to 90°. This position allows the device 100 to move, but also for a user to stand on the platform 10. Also, this position gives the possibility of installing up to four golf bags 300 on the mast 11 in accompanied mode, that is to say when the device 100 automatically follows the users, and up to 3 bags then allowing in this configuration a user to be transported by the device 100. The device 100 is therefore easily adaptable according to the carrying need.

The golf bags 300 are installed around the mast 10 and held on said mast by means of a plurality of elastic straps 22 which are inserted into the passage holes 122 of the object attachment 12. The length of the elastic straps 22 is adjusted by tensioning said straps and locking them by means of the screws 124. Thus, the device 100 is able to transport golf bags 300 of different volumes because said device adapts to all kinds of containers as well as objects.

In the , mast 11 and platform 10 form an angle α _mast close to 45°.

This configuration also allows the device 100 to be moved when said device is in automatic user tracking mode. In this configuration, up to two golf bags 300 can be installed on the device 100. In addition, the _mast angle α is adjusted according to the needs of the user(s), in particular to facilitate the gripping of equipment (here golf clubs).

There represents a functional diagram of the control unit 20 which comprises, in the preferred embodiment, an electrical energy storage means 207, connected to a charge and discharge controller 206, the electrical energy storage means 207 then supplying a transmitter/receiver module 205, receiving the movement instructions from the user of the device, said instructions being transmitted to a control means 204 of the drive wheels 18g-d.

In this particular embodiment, the control unit 20 also comprises a memory 201, for storing program instructions as well as data, a data processor 202 capable of executing at least one step of a method for controlling the device 100, and a means for transferring incoming and outgoing information 203, such as a wired or wireless network interface or a USB port, making it possible in particular to update the program and to retrieve data for the maintenance of said device.

In a particular embodiment, the electrical energy storage means 207 can easily be changed by another equivalent storage means, in order to have greater energy autonomy during use.

These particular embodiments are given as examples, and do not represent limits to the present invention. Indeed, to implement the method for controlling the device 100, the person skilled in the art has the ability to use control units 20 having functionalities that are all or partly identical to those described above.

In a particular embodiment of the invention, the device 100 moves autonomously by means of a plurality of ultrasonic or infrared sensors, positioned at the front, rear and sides of said device. These ultrasonic or infrared sensors are connected to the control unit 20 and will make it possible to detect obstacles located between the device 100 and the user when said device moves.

In another particular embodiment of the invention, the control unit 20 comprises a geographic positioning sensor (GPS) for geolocating the device 100 in a usage area. Thus, it is possible to program the device 100 so that it does not move in certain areas (for example greens and bunkers of a golf course), by entering proprietary cartographic data or data from a geographic information system into the control unit 20.

Also, the geographic positioning sensor makes it possible to program routes over a usage area. In addition, it is also possible to memorize a route by recording geographic coordinates in the control unit 20 when the device 100 is in manual piloting mode for example.

In a particular embodiment, the movement of the device 100 is carried out by means of a computing device, such as a smartphone, a tablet or any other similar equipment, where a destination to be reached is selected.

The destination to be reached is selected via a graphical interface that may or may not be touch-sensitive, and the geographical coordinates of the destinations to be reached are known in advance and entered either in the control unit 20 or in an application of the computer device. One of the users of the device 100, or a third person located remotely, can select the destinations to be reached.

As mentioned above, the materials from which the main elements of the device 10 are preferably manufactured are not a limit to the present invention. Indeed, the person skilled in the art has the ability to manufacture all or part of the device 10 with other types of materials than those given as examples in the description. On the other hand, and in the preferred embodiment, the choice of materials is made in a search for reducing the mass of the device 100 so that it is less than fifteen kilograms but also in order to respond to a recycling concern.

Beyond the example of application in the field of golf, the carrying device 100 can easily be used in gardens or vineyards, to help with daily tasks (market, transport of loads, etc.), but also to make daily life easier for people with disabilities.

It can also be a means of transporting people by adding a removable seat on the platform 10 by means of a conventional fastening system (not shown here) and known to those skilled in the art. The removable seat is adjustable in height to adapt to the user and thus provide maximum comfort, by means of a jack for example.
