Description

Trolley to support and weigh a container

The invention relates to the field of transport trolleys. It finds its application in particular for distribution surfaces such as supermarkets. It relates more specifically to the integration of measuring devices within trolleys in order to weigh the items selected by the user and placed in the trolley.

As is known, supermarkets provide self-checkout devices called automatic checkouts allowing people doing their shopping, once all of their shopping has been put in the cart, to count the amount to be paid and to settle it. of this sum. This includes a step of scanning each item, through an optical reader, then a step of weighing each selected item. This weighing step makes it possible in particular to ensure that each item placed by the user in the cart has been scanned and therefore has been counted for payment.

These automatic checkouts as described are often made available to users to allow firstly to limit long and painful queues for the collection of races and secondly to increase the number of collections per unit of time and consequently increase productivity. supermarkets.

To completely eliminate these long and painful queues, there are nowadays trolleys whose function is to weigh the items selected by the user by themselves.

However, these trolleys are often not easy to use for the user. Indeed, it is not easy to handle these carts with ease.

In addition, these carts often have regular malfunctions and often lack precision. It follows that discrepancies are indicated between the items placed in the cart and those counted following the scanning step. This situation prevents effective identification of a fraud attempt. On the other hand, this situation is also delicate in that it can prove to be uncomfortable for the user in good faith.

Another disadvantage of this type of carts is that they are often bulky which makes it difficult to store them.

There is therefore a need consisting in proposing a solution to reduce, or even to eliminate at least some of the disadvantages mentioned above.

The present invention aims to satisfy this need.

The other objects, features and advantages of the present invention will become apparent from a review of the following description and the accompanying drawings. It is understood that other benefits may be incorporated.

SUMMARY

• au moins un châssis supporté par au moins trois organes d’appui configurés pour supporter de manière isostatique le chariot sur un sol, au moins deux desdits au moins trois organes comprenant chacun au moins un dispositif roulant, telle qu’une roue,

According to one aspect, the invention relates to a trolley, for example for a supermarket, comprising:

• at least one frame supported by at least three support members configured to support the trolley isostatically on the ground, at least two of said at least three members each comprising at least one rolling device, such as a wheel,
• a supporting structure supported by the frame.

Preferably, the trolley comprises at least one container in which at least one product is intended to be placed.

Preferably, the trolley comprises a suspension structure supported by the carrier structure and configured to suspend at least one container in which at least one product is intended to be placed. The trolley is configured so that the at least one container is entirely suspended from the suspension structure, for example by reception areas.

Preferably, the trolley comprises at least one measuring device carried at least in part by the suspension structure and being intended to measure at least one parameter relating to the weight of the at least one container when the container is suspended from the suspension structure. suspension.

Optionally, but advantageously, the suspension structure, advantageously the frame, the at least one container and the frame of said trolley are shaped to cooperate with a suspension structure, advantageously a frame, at least one container and a frame of another carriage so as to allow the at least partial nesting of at least part of said other carriage in at least part of said carriage by cooperation of the suspension structure, advantageously of the frame, of the at least one container and of the chassis of said other trolley with the suspension structure, advantageously the frame, the at least one container and the chassis of said trolley.

Optionally, but advantageously, the suspension structure, advantageously the frame, the at least one container and the chassis of said trolley are shaped to cooperate with the suspension structure, advantageously the frame, the at least one container and the chassis of another carriage so as to allow the at least partial nesting of at least part of said carriage in at least part of said other carriage by cooperation of the suspension structure, advantageously of the frame, of the at least one container and the frame of said cart with the suspension structure, advantageously the frame, the at least one container and the frame of said other cart.

Thus, both a part of a first carriage enters a second carriage and at the same time another part of the second carriage enters the first carriage.

Optionally, but advantageously, the suspension structure of said carriage is shaped to cooperate with the suspension structure of another carriage so as to allow the at least partial nesting of said carriage in said other carriage by cooperation of the suspension structure of said carriage with the suspension structure of said other carriage. According to one embodiment, the suspension structure of said carriage is preferably shaped to cooperate with the suspension structure of another carriage so as to allow the at least partial nesting of the supporting structure of said carriage in a supporting structure of said other carriage.

Thus, the present invention offers the user a trolley allowing the weighing of the at least one container and the at least one product that he wishes to buy while allowing him to store the trolley easily and in a space-saving manner. These two functions are made possible in particular by means of the presence of the suspension structure.

In addition, the present invention allows both supermarkets to fight against existing fraud by known self-checkout systems and both to obtain considerable space saving for the storage of the trolley when not in use. .

The present invention makes it possible to integrate very few mechanical, mobile or moving parts. This increases the robustness and reliability of the present invention.

Indeed, carts are regularly abused by users, so it is a great advantage to have robust carts. The present invention, in addition to the multiple innovations of design and use that it brings, makes it possible to have a robust trolley.

It is specified that in the context of the present invention, the term “identical” used such as for example “a first element identical to a second element” means that these two elements have structurally and/or functionally similar characteristics.

In all the embodiments which are described below, the terms trays, containers, boxes or receptacles are considered equivalent and can be substituted for each other.

We will now describe the invention according to its many embodiments through Figures 1 to 32.

The present invention relates to a trolley 1, for example for a supermarket as described below. The trolley 1 is a transport trolley, thus making it possible to transport loads. By way of non-limiting example, these charges are shopping items placed in a container.

The trolley 1 could also be used in all industrial fields requiring the transport of loads, such as the field of the food industry or even in airports for the transport of luggage.

Figures 1 to 11 represent the trolley 1, which comprises at least one device 50 for measuring a parameter relating to the weight of the at least one container and of the at least one product. The at least one product is generally placed in the at least one container by the user.

According to one embodiment, the container may be a hanging tray 40 as shown in Figures 1 to 9 for example. According to another embodiment compatible with the previous one, the container can also be a bag 90 of the plastic bag, tote bag or rigid bag type as represented in FIGS. 8 and 9 for example. In general, the at least one container (40, 90) can be any element whose function is to contain the at least one product.

The measuring device 50 can comprise at least one force sensor 51, which can also be referred to as a force sensor, represented by FIG. 11 for example. The measuring device is configured to measure a parameter relating to the weight of the at least one container (40, 90) and of the at least one product that it contains. For example, the measuring device 50 can be configured to form a cantilever-type weight sensor.

According to one example, the force sensor 51 comprises a strain gauge or strain gauge. The force sensor 51 can be a so-called "single point" sensor, S-shaped. This makes it possible to measure a parameter relating to the weight of the at least one container (40, 90) and of the at least one product 'it contains. In a preferred case where the at least one container (40, 90) has a negligible weight, the measuring device 50 mainly measures a parameter relating to the weight of the at least one product. In an alternative case where the at least one container (40, 90) has a non-negligible weight, the present invention proposes a trolley 1 capable of subtracting the weight of the at least one container (40, 90) from the total measured weight in order to obtain only the measurement of the weight of the at least one product.

Trolley 1 comprises at least one frame 10. By "frame" is meant a rigid frame intended to support other elements of trolley 1. Frame 10 is supported by at least three support members 20 configured to support the trolley 1 on a floor isostatically. At least two of the at least three bearing members 20 each comprise at least one rolling device, preferably the at least three bearing members 20 include at least one rolling device. The rolling device preferably comprises at least one wheel. According to one example, the rolling device is a wheel. Alternatively, the rolling device is a sphere reducing the point of contact between the rolling device and the ground, making it possible to increase the maneuverability of the trolley. According to another example, the rolling device is a caterpillar. The at least three support members 20 are present according to all the embodiments described by the invention. In addition, the carriage 1 comprises a carrier structure 200 supported by the frame 10. By "carrier structure" is meant any element or set of elements performing a support function. By way of example, the load-bearing structure 200 can take the form of a frame, or vertical beams or even columns.

The load-bearing structure 200 supports a suspension structure 30. By "suspension structure" is meant any element or set of elements performing a suspension function. By way of non-limiting example, the suspension structure 30 can be one of a bar, a platform, a hook, a handle, a part of a frame. The suspension structure 30 has reception areas 31. The reception areas 31 are configured to suspend the at least one container (40, 90) in which the at least one product is intended to be placed.

Preferably, the measuring device 50 is carried by the suspension structure 30. Thus when the at least one container (40, 90) contains the at least one product and is suspended by the suspension structure 30, the user can know the weight of the at least one container (40, 90) and of the at least one product by means of the measurement carried out by the measuring device 50.

Preferably, the measuring device 50 carried by the suspension structure 30 can measure weights of between 1 g and 30 kg per sensor.

By way of non-limiting example, the suspension structure 30 has a length dimension L2 configured to suspend at least one, preferably at least two and advantageously at least three containers 90. Thus the suspension structure 30 is long enough to allow the user to suspend all of the containers 90. Advantageously, it has a width dimension l2.

Furthermore, the carriage 1 comprises a gripping device 60 as shown in Figures 1 to 4. This gripping device 60 is intended to be apprehended by the user. Thus the user can manually drive the carriage 1. The gripping device 60 can be in the form of handles, or even in the form of a rigid bar. The carriage 1 is also advantageously configured so that when a force applied by a user to the gripping device 60 has a vertical component, this vertical component is transmitted from the gripping device 60 to the frame 10 then to the ground without being transmitted to the supporting structure 200 and to the suspension structure 30. Thus when the user browses the various departments of the supermarket, and consequently is led to grasp the gripping device 60 of the trolley 1 to move it, the force applied by the user on trolley 1 does not disturb the measurement.

In order to communicate the measured weight to the user, the trolley 1 can comprise at least one display device 70. The display device 70 is configured to display information of the type at least one of: instructions for user, verification of the validation of at least one product, list of validated products, various information on the at least one product, price of the at least one product, photos representing the at least one product.

In addition, the trolley 1 includes at least one optical reader 71. This allows the user to read the information stored in the form of barcodes of each product before inserting it into the at least one container (40, 90) and/or place it in trolley 1.

According to one embodiment, the optical reader 71 records the referenced price/kg of the at least one product and the display device 70 can display the price to be paid by the user for this product according to the weight measured by the measuring device 50.

The use of an optical reader 71 makes it possible to associate a price with each selected product, depending or not on the weight of the product. In addition, it helps to avoid fraud when shopping in supermarkets. Indeed, it is known that many people do not voluntarily scan all the selected products in order to pay less expensive races. This weighing step makes it possible in particular to ensure that each product placed by the user in the trolley 1 has indeed been scanned and therefore has been counted for its payment. Indeed, if the weight measured by the measuring device 50 of a product is different from the weight of the product read by the optical reader through a bar code for example, it is then easy to know that different products or additional items have been introduced into trolley 1, including without having been scanned beforehand by the optical reader 71.

In a particularly advantageous manner and in order to compensate for a temporal derivative error of the measuring device 50, the measuring device 50 can comprise a so-called “virtual tare” tare carried out between each insertion of the at least one product within the carriage 1. This makes it possible to avoid multiplying the margin of error on each product, indeed once a product has been validated, the reference weight is updated and becomes the weight weighed during validation. Although the weight of the at least one product is not displayed by the display device 70, the invention includes a validation step, which includes algorithms using the data relating to the weight of the at least one product . This makes it possible to improve the detection of fraud or to carry out statistical analyses. In addition, the absence of the display of the weight of the at least one product 90 on the display device 70 makes it possible to prevent the user from being able to substitute the at least one product with another product easily by having the parameter relating to the weight visible on the display device 70.

The optical reader 71 can be removable from the carriage 1 or can be fixed.

Advantageously, the display device 70 is carried by the gripping structure 60. This allows the user to always have a view of the price of his races when he browses the various departments. Thus the user can adapt as he goes shopping, his purchases according to his budget.

Another aspect of the invention is that the suspension structure 30 is shaped to cooperate with the suspension structure 30 of another trolley 1 so as to allow the interlocking at least partially of the supporting structure 200 in a supporting structure 200 another trolley 1. Thus the present invention describes through its many embodiments, a trolley 1 allowing both a step of weighing the at least one container (40, 90) and the at least one product and both a very compact nesting of the carriage 1 in another carriage 1 having an identical suspension structure.

Interlocking is the ability to insert at least part of a carriage, typically at least 10% and preferably at least 20% and and preferably at least 30% of the length of a carriage into another cart.

By way of non-limiting example, the interlocking distance, that is to say the length of a carriage that can be inserted into another carriage is 300 mm, then considering carriages of standard dimensions of the order of magnitude 1300 mm x 650 mm, it is possible to nest 36 trolleys in 3 separate nesting rows, ie 12 trolleys per row in the standard dimensions of a parking space.

We will now describe the preferred embodiment of the present invention.

The carriage 1 advantageously has a front part and a rear part. The rear part corresponds to the part of the carriage 1 comprising the gripping device 60, the front part is located opposite the rear part.

According to a preferred embodiment and as shown in Figures 12 to 18, the suspension structure 30 is articulated in rotation on the support structure 200, around a substantially horizontal axis. It is advantageously tiltable downwards. Alternatively, it tilts upwards. This rotation can be done by means of a hinge 17 performing a pivot connection. The hinge is advantageously carried on the front part of the carriage 1. The suspension structure 30 has a carrying configuration and a storage configuration, different from the carrying configuration. The carrying configuration allows the suspension of at least one container 90 by the suspension structure 30 in the carrying configuration. In the carrying configuration, the suspension structure 30 is in contact with an abutment carried by the supporting structure 200 preventing rotation of the suspension structure 30 under the effect of gravity. The storage configuration allows the interlocking at least partially of the carriage 1 with another carriage having an identical suspension structure in the storage position, the suspension structure 30 being at a distance from the stop.

By way of non-limiting example, the suspension structure 30 is mounted in free rotation on the support structure 200. The carriage 1 has bevels, preferably on rollers on the front part of the suspension structure 30 and on the rear part of the suspension structure 30 so that the suspension structure 30b of a second carriage 1b is configured in such a way as to lift the first suspension structure 30 of the first carriage 1a in order to allow interlocking.

As indicated previously, and preferably, the suspension structure 30 is shaped so as to have a serrated upper surface 32 forming said reception areas 31 as shown in FIG. 10. Thus it is easy for the user to position for example handles or handles 91,92 of the at least one container 90 on the suspension structure 30. In this case, the suspension structure 30 can be configured so as to present at least one suspension bar 34. The suspension bar 34 then comprises the measuring device 50 of the at least one container 90 as shown in Figure 11. In addition, the suspension bar 34 is shaped to at least partially penetrate the at least one container 90, preferably to pass through the handle or handles 91, 92 for example of the at least one container 90. Consequently, the suspension bar 34 has a free end.

Advantageously, the suspension bar 34 has a length dimension configured to suspend at least one, preferably at least two and advantageously at least three containers 90.

The hinge 17 is advantageously located on the front part of the carriage 1. In order to allow interlocking, FIG. 15 shows that the suspension structure 30a of the first carriage 1a tilts upwards by means of the hinge 17 to leave up to the non-inclined suspension structure 30b of a second carriage 1b.

Preferably, the at least one container 90 is removed from said carriage 1 via the front part of the carriage 1. Indeed, it suffices to slide the at least one container 90 from the reception areas 31 towards the free end of the suspension bar 34 to remove the at least one container 90. The user then does not need to lift the at least one container 90 from its height to remove it from the trolley 1.

According to a preferred mode of the invention compatible with the previous embodiment and as represented in FIGS. in Figures 5 to 9 that the tray 40 is fully suspended advantageously by at least one flange 41 or 42, preferably by at least two flanges 41,42, advantageously opposite one another. It is possible that each rim 41, 42 includes at least one additional device 43 for measuring the weight of said suspended tray 40 and at least one product it contains. Preferably, the additional device 43 is an S-type sensor. Thus, the suspended tray 40 makes it possible to contain heavier and/or bulkier products such as products that cannot be placed in the at least one container 90 suspended by the suspension structure 30. The present invention then makes it possible to measure a parameter relating to the weight of heavy and/or bulky products. “Heavy” means products weighing between 3 and 30 kg.

In addition, the suspended tray 40 may include at least one opening 44 configured to accommodate at least the suspension bar 34 of at least one other trolley having an identical suspension bar and when the trolley 1 and the other trolley are nested l with each other. This makes it possible to authorize the interlocking of the carriage 1 in another carriage by preventing the suspension bar 34 and the suspended tray 40 from interfering with the interlocking.

Advantageously and as illustrated in Figures 15 and 16, the second carriage 1b can nest in the first carriage 1a until the tray of the second carriage 1b almost comes into contact with the tray 40 of the first carriage 1a . According to a preferred example, when the suspension bar 34 is inclined upwards, it does not exceed the height corresponding to the gripping device 60.

The suspension bar 34 is optionally articulated in rotation on the carriage 1 by means of a hinge.

According to a non-limiting example, the suspended tray 40 can be removable from the carriage 1. This facilitates fitting in the case where the suspended tray 40 does not include at least one opening 44. Indeed, it is then sufficient to the user to remove the suspended tray 40 to fit the carriage 1 with another carriage.

Figures 17 and 18 describe the interlocking of the first carriage 1a with a second carriage 2a and a third carriage 3a. The interlocking of trolleys can be achieved with a large number of trolleys.

Figure 33 illustrates an embodiment in which the suspension structure 30 is mounted for rotation about a horizontal axis. More specifically, the suspension structure 30 has a first arm 11 and a second arm 12 each having a proximal end articulated in rotation on the carriage 1, typically on the supporting structure 200. This rotational articulation can be ensured by a hinge 17. The first arm 11 and the second arm 12 each have a distal end which are mechanically linked to each other by a profile. The first arm 11, the second arm 12 and the profile thus define an outline, which can be open or closed. In the carrying configuration, the first arm 11 and the second arm 12 are in contact with a stop 19 carried by the support structure 200. This stop 19 takes up at least part of the weight of the suspended containers 90 of the suspension structure 30. In the storage configuration, the first arm 11 and the second arm 12 are moved away from the stop 19 to be raised. For this, these arms 11, 12 are driven in rotation around the axes on which they are mounted on the supporting structure 200.

Preferably, the trolley 1 comprises at least one actuator 18 configured to hold the suspension structure 30 in position when the suspension structure 30 is in the storage configuration, at least when the suspension structure 30 does not suspend any container 90. Typically, the actuator 18 has one end articulated in rotation on the carrier structure 200 and another end articulated in rotation on one of the arms 11, 12 or on a structure integral with one of these arms 11, 12. Preferably, the carriage 1 comprises two cylinders 18, each of the cylinders being connected to one of the arms 11, 12. The suspension structure 30a of the first carriage 1a is adjusted in the storage configuration so as to be nested at least partially with at least a second trolley 2a having an identical suspension structure 30b set in storage configuration. For this, the hinge 17 is located on the rear part of the carriage 1. In this case, the suspension structure 30a of the first carriage 1a and the suspension structure 30b of the second carriage 2b can be tilted upwards so as to allow the interlocking of the first carriage 1a with the second carriage 1b. Interlocking is possible until one of the carrier structure 200a, the suspension structure 30a of the first carriage 1a is in contact with one of the carrier structure 200b, the suspension structure 30b of the second carriage 1b .

Figure 34 illustrates the interlocking of several carriages 1 illustrated in Figure 33. The suspension structures 30 are raised so as to be placed in their storage configuration. The suspension structure 30 of a first carriage 1a then does not hinder the fitting of a second carriage 1b into this first carriage 1a.

This embodiment allows a particularly high interlocking rate, that is to say that the interlocking distance is significant. This embodiment thus makes it possible to increase the compactness of the storage of a plurality of trolleys 1.

We will now describe through Figures 19 to 21, another embodiment of the present invention compatible with the previous ones.

According to this embodiment, the suspension structure 30 has a dimension in height H which decreases along a direction corresponding to the direction of nesting 500 of the second carriage 1b in the first carriage 1a so as to allow nesting in the less partially of the suspension structure 30b of the second carriage 1b in the suspension structure 30a of the first carriage 1a. In this way, the second carriage 2b can be nested at least partially in the first carriage 1a.

In a preferred case, the suspension structure 30 comprises at least a first arm 11 and a second arm 12 extending respectively along a first direction and a second direction, the first direction and the second direction being concurrent, and on both sides. the other of said carriage 1. One of the first arm 11 and the second arm 12 then advantageously comprises the measuring device 50.

Advantageously, the first arm 11 and the second arm 12 are shaped so as to each have at least two horizontal portions 13 and at least one vertical portion 14 separating the two horizontal portions 13, so as to form a staircase structure for example and thus to allow the interlocking of said carriage 1 in part at least with at least one other carriage having an identical suspension structure by nesting the suspension structure 30a of said first carriage 1a with the suspension structure 30b of said at least one second carriage 1b , preferably by nesting the first 11a and the second arm 12a of said carriage 1a respectively with the first 11b and the second arm 12b of said at least one other carriage 2b. Preferably, the vertical portions 14 are intended to partly support at least the at least one container 90 and the at least one product. The at least one measuring device 50 is then carried by at least one horizontal portion 13.

According to this embodiment, the interlocking distance corresponds to the length of the shortest horizontal portion 13 of the first arm 11 and second arm 12 combined.

Thus the user can easily nest the carriage 1 with another carriage 1. This interlocking mode makes it possible to reach interlocking distances of the order of 23% of the length of a carriage 1. Thus at least 23 % of the length of a carriage is inserted into another carriage. By way of non-limiting example, the interlocking distance is of the order of 300 mm. This then allows a considerable saving of space for the storage of trolleys when not in use. This increases the number of interlocking trolleys in a defined space. Thus the carriage 1 as described by the invention is not bulky. Consequently, the presence of the suspension structure 30 does not disturb the ability of said carriage 1 to be nested.

According to an embodiment illustrated in FIG. 21 for example, the carriage 1 comprises at least one frame 100 carried by the chassis 10. The frame 100 is represented in FIG. 31 for example. The carriage 1 is configured so that when a force applied by a user on the frame 100 has a vertical component, this vertical component is transmitted from the frame 100 to the chassis 10 then to the ground without being transmitted to the supporting structure 200 and to the suspension structure 30. This ensures that no external element disturbs the measurement made by the measuring device 50 of the parameter relating to the weight of the at least one container 90 and of the at least one product. By "external element" is meant for example the support of a person on the suspension structure 30 of the carriage 1.

Thus, the presence of the frame 100 allows the user or another person to lean on said frame 100 without disturbing the measurement performed by the measuring device 50.

Very advantageously, frame 100 is configured to define an envelope enclosing an internal volume. Preferably, the reception areas 31 of the suspension structure 30 are located within said internal volume. Thus the suspension structure 30 is advantageously not accessible for the support of a person. All risks of disturbances in the measurement of the parameter relating to the weight are then avoided. The measuring system is then endowed with high precision and high reliability.

The supporting structure 200 is also located inside the internal volume. For this purpose, the support structure 200 is not easily accessible for the support of the user or another person on it.

According to an alternative example not shown in the figures, the first arm 11 and the second arm 12 are curved so as to allow the nesting of the first and second arms 11b, 12b of a second carriage 1b in the first and second arms 11a, 12a of the first carriage 1a.

We will now describe another embodiment of the present invention through Figures 25 to 27. As shown in Figure 25, the suspension structure 30 is configured so as to allow the variation of said length L2. Indeed, it is possible to vary the length L2 in order to adapt the carriage 1 to the quantity of races carried out by the user. The length L2 of the suspension structure 30 can be adjusted by the user before the start of the races. The user can also change the length L2 of the suspension structure 30 when the at least one container 90 is already suspended. The suspension structure 30 can then be reduced by at least 70% of its initial length L2. This makes it easier to store carts and allows more carts to be nested in a limited space.

Preferably, the first arm 11 and the second arm 12 comprise telescopic portions 16, which are each configured to present a deployed configuration and a folded configuration. FIG. 25 shows the deployed configuration in which said first 11 and second 12 arms are configured to partly support at least the at least one container 90 suspended from the suspension structure 30. Said first 11 and second 12 arms support in particular the at least one container 90 by the reception areas 31 arranged on the side face 32 of the suspension structure 30. Figures 26 and 27 show the folded configuration of the telescopic portions 16, in which the first carriage 1a is adapted to nested with at least a second carriage 1b having an identical suspension structure 30b. The telescopic portion 16a of a first carriage 1a cooperates with the telescopic portion 16b of a second carriage 1b so that at least one reception area 31 carrying the respective measuring device 50 of each telescopic portion 16a, 16b come in contact with each other. This makes it possible to increase the nestability of a first carriage 1a with a second carriage 1b and thus increase the nestability of a series of carriages. The storage of trolleys then takes up less space.

In this embodiment, the suspension structure 30 has at least one side face 32 so that the reception zones 31 of the suspension structure 30 are located on the at least one side face 32. The zones of reception 31 can be handles, preferably half-moon, or any abutment surface allowing the user to hang, for example, handles or handles of the at least one container 90. Alternatively , the reception areas 31 are hooks, hooked directly to the suspension structure 30. The force sensor 51 can be a button-type sensor directly integrated on the reception areas 31. This makes it possible to avoid the weighing of the suspension structure 30 and this makes it possible to directly weigh the at least one container 90 and the at least one product.

According to an embodiment not illustrated, the suspension bar 34 can optionally have a telescopic portion 16.

We will now describe another embodiment of the present invention through Figures 28 to 30. According to this embodiment, the suspension structure 30 is held on the supporting structure 200 at the rear of the carriage 1. In addition , the suspension structure 30 has at least one free end at the front of the carriage 1.

Advantageously, the width l2 of the suspension structure 30 is shaped to decrease along a direction corresponding to the direction of engagement 500 of said carriage 1 in another carriage so as to allow the nesting at least partially of the carriage 1 in another carriage having an identical suspension structure.

According to a preferred embodiment, the first arm 11 and the second arm 12 of the suspension structure 30 are held to the support structure 200 at the level of the rear part of the carriage 1. In addition, the first arm 11 and the second arm 12 are secured to each other by means of at least one telescopic securing portion 15. The first 11 and second 12 arms are advantageously secured to each other at their free ends, which are located at the front of the carriage 1. The telescopic securing portion 15 is configured to present an extended configuration and a folded configuration.

Figure 28 shows the deployed configuration, in which the first arm 11 and the second arm 12 are in a position away from each other. In the deployed configuration, the first arm 11 and the second arm 12 are preferably parallel to each other and the telescopic securing portion 15 is configured in its maximum length. Said first 11 and second 12 arms support in particular the at least one container 90 by the reception areas 31 arranged on the side face 32 of the suspension structure 30.

Figures 29 and 30 show the folded configuration, in which the first arm 11 and the second arm 12 are in a position close to each other. According to a more than advantageous mode, in the folded configuration the first arm 11 and the second arm 12 are concurrent with respect to each other. Indeed, the first 11 and second 12 arms, being held to the support structure 200 at the rear of the carriage 1, when the telescopic securing portion 15 is folded, the first 11 and second 12 arms approach one another. another at the front of the carriage 1 so as to become concurrent with each other. This allows the suspension structure 30a of the first carriage 1a to be able to be nested with at least one second carriage 2a having an identical suspension structure 30b. For this, the telescopic securing portion 15a of the first carriage 1a and the telescopic securing portion 15b of the second carriage 1b are preferably each in the folded configuration. Thus the first 11 and second 12 arms of the second carriage 1b are able to be inserted into the first 11 and second 12 arms of the first carriage 1a.

In addition, there may be an infinity of intermediate positions between the deployed configuration and the folded configuration of the telescopic securing portion 15.

According to another embodiment and as shown in Figure 22, the carriage 1 comprises at least one receptacle 80 intended to receive at least one product. The receptacle 80 is advantageously supported by the frame 10. The parameter relating to the weight of the receptacle 80 and of the at least product that it contains is measured by the measuring device 50.

More than advantageously and as shown in Figures 22 to 24, the receptacle 80 has at least one side wall 81 or 82 configured to be rotatable around an axis of rotation 83. The axis of rotation 83 is preferably horizontal, so that the wall 81 or 82 can pass from a configuration in which the wall 81 or 82 forms a container with the other walls of the receptacle 40 to a position in which the said carriage 1 is nested at least partially with at least one other carriage having an identical receptacle. According to an example of interlocking of the first carriage 1a with a second carriage 1b, the receptacle 80b of the second carriage 1b is inserted into the receptacle 80a of the first carriage 1a in the following way: the side wall 81b of the second carriage 2b pushes the side wall 82a of the first carriage 1a so as to generate the rotation of the side wall 82a around the axis of rotation 83. The receptacle 80b thus penetrates the receptacle 80a until the side wall 81b is in contact with the side wall 81a .

According to an embodiment illustrated in figure 32 for example, the carriage 1 comprises at least one frame 100 carried by the frame 10. The frame 100 advantageously matches at least part of the contour of the receptacle 80.

Thus, as described above, the presence of the frame 100 allows the user or another person to lean on said frame 100 without disturbing the measurement performed by the measuring device 50.

According to another embodiment illustrated in Figures 35 to 38, the first and the second arm 11, 12 of the suspension structure 30 are articulated in rotation on the supporting structure 200, around a substantially horizontal axis. The first and second arms 11, 12 are advantageously tiltable upwards. This rotation can be effected by means of the hinge 17 performing a pivot connection along a substantially horizontal axis. The hinge 17 is advantageously carried on the front part of the carriage 1. In the carrying configuration as illustrated in FIG. 35, the first arm and the second arm 11, 12 are each in contact with at least one stop 19, carried by the support structure 200 preventing a rotation of the suspension structure 30 under the effect of gravity. The storage configuration as illustrated in FIGS. 36 and 37 allows said first carriage 1 to be nested at least partially with another carriage 1 having an identical suspension structure in the storage position, the suspension structure 30 being at a distance of the stop 19. In addition, it is illustrated in FIG. 38 that the force sensor 51 can be in contact with at least one hook, which serves to suspend said containers 90. The force sensor 51 can for example be of the “integrated button” type. Thus the user can directly suspend the containers 90 on the at least one hook, intended for this use. In addition, the first 11 and second 12 arms can advantageously comprise at least one force sensor 51 of the cantilever type.

According to another embodiment not illustrated in the figures, the rolling device 20 may comprise a device for measuring at least one parameter relating to the weight of the at least one container. This allows the entire trolley to be weighed directly, as well as the containers.

We will now describe another embodiment of the present invention, as illustrated in Figures 39 to 55. The suspension structure 30 comprises at least two containers 300, preferably three containers 300 as they are. shown in Figures 39 to 44. In the rest of the description, the containers can also be referred to as bins or containers.

All the characteristics and all the technical effects described in the previous modes of relationship can be combined with the embodiment which follows and which is illustrated in figures 39 to 55.

Advantageously, at least two containers forming trays or adjacent boxes are nestable at least in part. The containers are suspended. We can thus say that they are configured to be telescopic or to slide into each other like Russian dolls. Thus, in a retracted configuration, the containers are at least two by two partially nested. At least a portion of a first container is then housed in a second container which is adjacent to it. Preferably, the second container is located closer to the rear of the cart than the first container. As in the example illustrated in figure 44, provision can be made for the same container to partly or entirely house more than one other container. In this example, container 300a completely houses containers 300b and 300c.

Advantageously, the nesting of a first trolley in a second trolley causes the displacement of the containers 300 of the second trolley and their nesting at least two by two. Preferably, this movement is sliding. The sliding direction 4 and the normal forward direction 3 of the carriage are contained in the same plane. The normal direction of travel 3 of the trolley extends the direction of travel when the user pushes the trolley forward without making a turn. This direction 3 is referenced in figures 49 and 52.

More generally, at least one of the containers is slidably mounted in the carriage and relative to at least one other container.

Each container 300 is formed of a bottom wall 303 and of at least two side walls 304. The bottom wall 303 has a length dimension Lpf, which corresponds to the distance separating the two side walls 304 of each container 300 The dimensions Lpf1-Lpf3 of each container are illustrated in Figure 42. The two side walls 304 can be perpendicular to the bottom wall 303 and oppose each other. More generally, the two side walls 304 extend from the bottom wall 303 and define with the latter a "U" shape whose branches form a right angle or an angle greater than 90° with the bottom wall 303.

By "wall" is meant a face comprised in a single plane. Each container 300 remains open and has at least one open surface, perpendicular to the side walls 304. The side walls 304 have edges 3040. For example three edges among the edges 3040, form a U and delimit the at least one open surface. Preferably, each container 300 has at least two open surfaces, opposite to each other so that each container 300 is in the form of a U. According to a very advantageous example, the rear container 300a, it that is to say the one positioned furthest to the rear of the carriage 1, has a bottom. This bottom defines a third side wall 305 connecting the other two side walls 304 and then leaving a single surface open to the rear container 300a. According to an alternative example, each container 300 has a third side wall 305.

Figures 48 to 50 illustrate in detail the suspension of the containers 300 from the suspension structure 30. The containers 300 are entirely suspended from the suspension structure 30, advantageously by at least one flange 41 or 42 each forming a reception area, preferably by at least two flanges 41,42, advantageously opposite one another. The flanges 41, 42 are not fixed to the suspension structure 30, but form a sliding connection with the suspension structure 30. Thus, each flange 41, 42 forms a reception area configured to fully support or suspend a container 300a -300c. For example, each flange 41, 42 forms a slider which cooperates in sliding with a rail 306 of the suspension structure 30 to guide and support the container in its translation relative to the carriage. The rail 306 is clearly identifiable in figures 50. In this way, the containers 300 can translate along the suspension structure 30. In particular the containers 300 translate along an axis corresponding to the direction 4 of interlocking 500 of the carriage 1.

As will be specified later, the rail 306 is integral with or cooperates with at least one measuring device 50 so that the weight of the containers and of the articles placed in the containers are transferred to the rail 306 and is picked up by the device. measuring 50.

Preferably, the suspension structure 30 comprises at least two rails 306, the rails 3 being arranged in parallel and carried by each side of the carriage.

The three containers 300 are advantageously arranged in the following manner: they are aligned in the direction 4 of interlocking 500 of the carriage 1. The rear container 300a has the largest open surface, that is to say the bottom wall 303a of the rear container 300a has the greatest dimension in length Lpfa. The front container 300c, that is to say, the one positioned furthest forward of the carriage 1 has the smallest open surface, that is to say the bottom wall 303c of the front container 300c has the most small dimension in length Lpfc. Finally, the intermediate container 300b, that is to say the one positioned between the front container 300c and the rear container 300a, has an open surface between the open surface of the front container 300c and the open surface of the rear container 300a, c ie the bottom wall 303b of the intermediate container 300b has a length dimension Lpfb comprised between Lpfa and Lpfc. This allows the interlocking of the intermediate container 300b in the rear container 300a, and of the front container 300c in the intermediate container 300b as illustrated in Figures 45 to 47, the containers 300 are then in the so-called configuration compression. We will call "nesting container", each container 300 located in another container 300 and "nested container", each container 300 containing another container 300.

Particularly advantageously, the direction 4 of sliding of the containers is inclined relative to the horizontal. Thus, direction 4 of sliding of the containers and the horizontal, i.e. the direction of advance 3 of the carriage on a single flat, together define an angle alpha. This angle is illustrated in Figures 49 and 50. This direction 4 is inclined forwards. The end of the 306 rail closest to the front of the trolley is closer to the ground than the end of the rail closest to the rear of the trolley. This inclination, as well as the support structure 30 are configured so that the containers 300 slide forwards of the carriage under the effect of gravity. Thus, when the containers are empty or support articles, their weight drives them towards the front of the trolley and causes their deployment, that is to say during mutual separation.

Each side wall 304, 305 and bottom wall 303 of each container 300 has an inner surface and an outer surface. According to a more than advantageous mode, there is a spacing between the outer surface of the side walls 304 of the nested container and the inner surface of the side walls 304 of the nested container. This spacing can be between 0 and 50 mm. Similarly, there is a clearance between the outer surface of the bottom wall 303 of the nested container and the inner surface of the bottom wall 303 of the nested container. This spacing can be between 0 and 50 mm.

In addition, Figures 49 and 50 show the positioning of the measuring device 50 which is carried by the suspension structure 30 in the same way as for the embodiment shown in Figure 19.

In addition, according to an optional but preferred mode, it will be noted that at least one container and preferably the intermediate container 300b and the rear container 300a each have at least one guide rail 302, preferably two rails. Each rail 302 has the role of facilitating the guiding of the nesting container in the nested container. It also serves to stabilize the configuration of the containers 300. The rails are preferably arranged on the internal surface of the side walls 304 of the containers 300, preferably at mid-height of the containers 300. More generally, it is the nested container which has the rail 302. The rail 302 is directed in the direction 4 of interlocking 500 of the containers 300. Another advantage conferred on the rail 302 is to allow a better distribution of the weight. Indeed, by way of non-limiting example, the rail 302 carried by the intermediate container 300b translates on the rail 302 carried by the rear container 300a. Thus, the rail 302 carried by the intermediate container 300b exerts a support on the rail 302 carried by the rear container 300a. The rail 302 carried by the rear container 300a then supports at least part of the weight supported by the intermediate container 300b. The weight is then better distributed between the intermediate container 300b and the rear container 300a. This then facilitates the handling of the trolley 1 when the user is shopping.

Also advantageously, these rails 302 or slides have at least one of their ends a stop 3021. This stop is for example formed by the end of a groove or a slot which defines the rail 302 and which is formed in the internal face of the container. When a slider of the container which cooperates with the container carrying the rail 302 reaches the level of the stop 3021, then the slider is stopped and the container is blocked. This makes it possible in a particularly simple way to guide the containers together in translation and to control their stroke length.

Thus, under the effect of gravity, the containers tend to translate towards the front of the trolley. Their translation is interrupted when a container comes into abutment on the adjacent container. One of the containers therefore continues its course while the other container is stopped in its translation. This allows containers to deploy under gravity. This embodiment has the advantage of not requiring any action on the part of the user or any actuator to deploy the containers. The trolley according to this embodiment is therefore particularly easy to use, reliable and robust.

As will be described in detail below, in order to retract the containers, that is to say to fit them at least partially into each other, it is sufficient for the user to fit a first carriage at least partially into a second carriage. A stop carried by the second carriage comes into contact with the container located furthest forward of the first carriage and then causes the sliding of this front container, along the rail 306 (that is to say in the direction 4 of sliding) and towards the rear of the first carriage. This front container moves until it comes into contact with the container adjacent to it and drives the latter in turn by sliding towards the rear of the first carriage. The retraction of the containers is thus done telescopically. As will be seen later, this abutment carried by the second carriage may be a bottom wall of the container of the second carriage located furthest rearward. Alternatively, this stop can be carried by another element of the second carriage. According to a particularly advantageous embodiment, the container arranged furthest to the rear is configured to move towards the rear of the carriage when a force is applied to it typically, when the carriage is nested in another carriage. When the effort ceases to be applied to this container, this container returns to its rest position by simple gravity. This rearward movement has a stroke preferably between 5 and 30 centimeters. It further improves the interlocking rate of two carriages into each other.

The embodiment described by Figures 39 to 55 then has two possible configurations for the containers 300: a configuration called the deployment configuration illustrated in Figures 39 to 44 and a configuration called the retraction configuration illustrated in Figures 45 to 47.

The deployment configuration is the one that the user will favor when he does his shopping. Indeed, it is the configuration which makes it possible to have a large volume to dispose of all the additional containers 90 such as a bag or sachet. The at least one additional container 90 can be suspended by the reception areas 31 located on the internal surface of the side walls 304 of the containers 300. However, another possible option for the user is to directly place the at least an additional container 90 or the product directly on the bottom wall 305 that is to say the bottom wall of the rear container 300a of the first carriage 1a. To arrange the at least one additional container 90 in the containers 300, the invention has the advantage of proposing an opening on the front container 300c, an opening which corresponds to the open surface described previously. This allows the user to pass the at least one additional container 90 or the product directly through this opening without having to lift the at least one additional container 90 or the product by a height equal to the height of the suspension structure 30. The user then does not need to lift the at least one additional container 90 from its height to remove it from the trolley 1 or place it in the trolley 1. Thus, the user is spared Exercising too much physical effort which could tire him or even injure him. In this configuration, it is the containers 300 which form the receptacle 80 described above and shown in Figure 22.

Optionally, the front container 300c has a front stop 301 as shown in Figure 44. This makes it possible to retain the at least one additional container 90 or the products placed on the bottom wall 303 within the internal volume. Indeed, if the user is required to have rolling products or is required to push the trolley 1 on inclined floors, it is very advantageous to be able to retain the at least one additional container 90 and/or the products and thus preventing them from escaping from the cart and making amends.

Advantageously, when fitting a first carriage into a second carriage, the front stop 301 of the first carriage or its stop when there is no stop 301 comes into contact with the bottom wall 305 of the second carriage. This bottom wall 305 acts as a stop to stop the movement of the stop 301 and of the container 300c. When the nesting of the first carriage in the second carriage continues, this abutment causes the relative sliding of the containers of the first carriage and their telescopic or Russian doll nesting. This is shown in Figures 51 to 54 for example. In these figures, the containers of the second carriage are shown nested one inside the other to make this embodiment clearly understood. Naturally, this configuration of containers will be possible if the second trolley is itself nested in the third trolley (or if the user pushes the containers towards the rear of the trolley, which is not a normal case of use of the cart).

This embodiment of retracting or nesting the trolleys is particularly simple since it is done automatically when the user nests a trolley into another trolley. Furthermore, this embodiment does not require any actuator. It is therefore particularly easy to use and robust.

According to a non-limiting example, the front stop 301 is parallel to the third side wall 305 of the rear container 300a. According to a non-limiting example, it extends perpendicular to the two side walls 304 of the front container 300c and connects the two side walls 304 of the front container 300c. The stopper 301 has a height dimension less than half the height dimension of the front container 300c.

The retraction configuration is that which the user will favor for the storage of the trolley 1. Indeed, as illustrated in FIGS. 51 to 55, when the front container 300c and the intermediate container 300b are nested in the container rear 300a, all of the containers 300 occupy a volume that is substantially three times smaller than when the carriage 1 is in the deployed configuration. This allows a considerable saving of space during the storage of the carriage 1. By then considering carriages of standard dimensions of the order of magnitude 1300 mm×650 mm, it is possible to nest 36 carriages on 3 separate rows of interlockings, i.e. 12 trolleys per line in the standard dimensions of a parking space.

It can be seen in FIG. 53 that the nesting of the second carriage 1b in the first carriage 1a is possible until the third side wall 305 of the rear container 300a of the first carriage 1a is in contact with the open surface formed by the rear container 300a of the second carriage 1b, fitting is then stopped by the three edges 3040 presented by the opposite side walls 304 of the rear container 300a of the second carriage 1b.

In addition, it will be noted in Figures 53 and 54 that in this embodiment, the suspension structure 30 also has a dimension in height H which decreases along a direction corresponding to the direction of interlocking 500 of the second carriage 1b in the first carriage 1a so as to allow the suspension structure 30b of the second carriage 1b to fit at least partially into the suspension structure 30a of the first carriage 1a. In this way, the second carriage 1b can be nested at least partially in the first carriage 1a. The interlocking is then advantageously stopped when the suspension structure 30 of the first carriage 1a and the suspension structure 30 of the second carriage 1b rub together sufficiently and thus slow down the interlocking until the second carriage 1b stops.

As indicated above, provision is made for the trolley to be configured so that the container located furthest behind the trolley can slide along the rail 306 when a force is applied to it, typically when the trolley is nested in a another cart. This makes it possible to further reduce the volume occupied by several nested trolleys.

Said frame 100 can also be present in the embodiment illustrated in Figures 39 to 55. Thus, as described previously, the presence of frame 100 allows the user or another person to lean on said frame 100 without disturbing the measurement taken by the measuring device 50. In FIGS. 48 and 49 for example, it clearly appears that the suspension structure 30 is distinct from the frame 100. In a particularly advantageous manner, the frame 100 has a shape which conceals the suspension structure 30, typically rail 306 for the user. The latter therefore cannot or cannot easily access the suspension structure, typically the rail 306, for example to lean on it. The user on the contrary will come into contact and lean on frame 100.

In this example, the suspension structure 30 forms a rail 306 which extends under a section of the frame 100. Preferably, this section of the frame 100 forms an "L" or an inverted or inclined "U" and open towards the trolley interior. Preferably, and as illustrated in the figures, this profiled frame 100 forms a tube whose section defines a contour 101 closed with the exception of an opening 102, which extends longitudinally and which is configured to allow a mechanical connection between the containers and the guide rail. Typically, this opening 102 forms a slot which extends over all or part of the length of the frame profile 100 and which allows the passage of at least one flange 41, 42 for each container. The contour 101 and the opening 102 are referenced in figure 50. The rail 306 of the suspension structure 30 is housed inside the frame profile 100.

This makes it possible to delimit inside the profile a volume that is not accessible or not easily accessible from the outside of the trolley. Preferably, the rail 306 of the suspension structure 30 extends along this volume. This rail 306 is thus protected. At the very least, a user cannot lean on this suspension structure 30. This makes it possible to avoid distorting the measurement of the weight of the articles contained in the trolley. This therefore makes it possible to solve the problem consisting in improving the reliability and the precision of the measurement of the weight of the articles contained in the trolley. Furthermore, this makes it possible to improve the safety of the trolley by preventing a user from interfering with the slides on the rail 306, for example by trapping their fingers there.

Thus all the embodiments describe a suspension structure configured to allow the interlocking of the carriage in another carriage having an identical suspension structure.

In the examples described above with reference to Figures 39 to 63 the containers are delimited by solid walls, for example made of metal or plastic. According to another embodiment, only one, or several, or even all of the walls are formed of a mesh structure or an openwork structure as illustrated in FIG. 2.

In all the examples illustrated above, the containers or containers are rigid. They are not manually deformable. According to another exemplary embodiment, not illustrated, the plurality of containers or containers is replaced by a single container or deformable container. According to an exemplary embodiment, this deformable container is formed at least in part from fabric, and preferably entirely from fabric. It is configured to be compressed in order to selectively switch from an extended configuration to a retracted configuration. In the deployed configuration, it offers a first volume for receiving articles submitted by the user. In the retracted configuration, it does not accommodate articles or has a lower volume than in the deployed configuration.

The transition from the deployed configuration to the retracted configuration is carried out by fitting the carriage into another carriage. For this, provision can be made for a front part of the fabric container to come into contact with the other carriage and deform the container. To this end, provision can be made for the fabric container to have preferred deformation zones. These preferred deformation zones may for example comprise preformed zones configured to facilitate deformation. It can for example be bellows made of fabric or elastomer, rubber or for example.

The passage from the retracted configuration to the deployed configuration is preferably carried out by gravity. For this, the deformable container may have edges provided with rings or eyelets which cooperate with a guide element such as a rail, a rod or a guide cable, such as for example the rail 306 illustrated in FIG. 50. Preferably, this guide element is inclined with respect to the horizontal approaching the ground towards the front of the carriage. Thus, as for the embodiment illustrated in Figures 39 to 55, the front part of the deformable container moves by gravity towards the front of the carriage. For this, provision can be made for the front part of the deformable container to be sufficiently weighted.

According to a particularly advantageous embodiment, a trolley having the same frame 100 and the same suspension structure 30 can accommodate different types of containers. Thus, it is possible to selectively mount on the same carriage one or more fixed rigid containers, one or more sliding and telescopic rigid containers, one or more deformable containers.

We will now describe another preferred embodiment of the present invention through Figures 56 to 63.

According to the embodiment illustrated in FIG. 56, the trolley 1 advantageously has a container 40 and preferably a single container 40. This container 40 comprises a front part 103 and a rear part 104. The rear part 104 corresponds to the part of the container 40 closest to the gripping device 60, the front part 103 being located opposite the rear part 104. As illustrated below, the frame 10 also comprises a front part 105 and a rear part 106. The rear part 106 corresponds to the part of the frame closest to the gripping device 60, the front part 105 being located opposite the rear part 106.

According to this embodiment, the front part 103 of the container 40 has a width dimension 103a greater than the width dimension 104a of the rear part 104 of the container 40.

According to this embodiment, the front part 105 of the frame 10 has a width dimension 105a smaller than the width dimension 106a of the rear part 106 of the frame 10.

Indeed, according to a preferred embodiment and as illustrated in Figures 62 and 63, the carriage 1 is configured to partly receive at least one other carriage 1b in the storage configuration and advantageously to be partly received at least by the other carriage 1b.

Indeed, according to this embodiment, the front part 103 of the container 40 is wider in order to be able to come from either side of the rear part 104 of the container 40 from another trolley 1b in storage configuration. And preferably, the front part 105 of the frame 10 is narrower in order to be able to come into the rear part 106 of the frame 10 of another trolley 1b in storage configuration. Thus, it is the hanging container containing 40 of the front carriage 1b which penetrates inside the container 40 of the rear carriage 1a. As will be seen later, for these same rear 1a and front 1b carriages, during their respective interlocking, that is to say in the storage configuration, it is the frame 10 of the rear carriage 1a which enters at the inside the frame 10 of the front carriage 1b.

According to one mode of relationship, for these rear 1a and front 1b carriages, during their respective interlocking, it is the frame 100 of the rear carriage 1a which penetrates inside the frame 100 of the front carriage 1b.

Advantageously, the carriage 1a of the present invention is configured to present a part which fits into a part of another carriage 1b and to present another part which surrounds another part of another carriage 1b.

According to one embodiment, the suspension structure 30 comprises at least one suspension bar 34, at least one measuring device 50 comprising at least one force sensor 51, and at least one attachment 56 of the measuring device 50 to the frame 100 , and preferably frame 100.

According to one embodiment, the suspension structure 30 has a dimension in height H which decreases along a direction corresponding to the direction of nesting of said carriage 1 in another carriage 1b so as to allow nesting at least partially of the trolley 1 in another trolley 1b having a suspension structure 30 identical to the suspension structure of said trolley 30.

According to one embodiment, the frame 100 has a dimension in height which decreases along a direction corresponding to the direction of nesting of said carriage 1 in another carriage 1b so as to allow the nesting at least partially of the carriage 1 in another trolley 1b having a suspension structure identical to the suspension structure of said trolley 1.

According to a preferred embodiment, the measuring device 50 is inserted into the frame 100, preferably is arranged between two parts of the frame 100. Advantageously, the frame 100 can comprise a plurality of parts 101, 102. Preferably, one or several measuring devices 50 can be arranged between different parts of the plurality of parts of the frame 100.

According to a preferred embodiment and as represented in FIGS. 59 to 61, by way of nonlimiting example, the frame 100 comprises a first part 101 and a second part 102. Cleverly, the measuring device 50 is located between the first part 101 and the second part 102 so as on the one hand to secure the two parts together, and on the other hand to suspend the force sensor 51 so that any support on the frame 100 cannot come interfere with a weight measurement.

In FIG. 56, it can be seen that the front part 103 of the container 40 advantageously comprises a valve 400 arranged at the front of the carriage 1. In this non-limiting example, the valve 400 forms a wall of the container 40. This valve 400 is configured to lower when the carriage 1 fits into another carriage 1b, preferably when the front part 103 of the container 40 receives the rear part 104 of the container 40 of another carriage 1b. According to this embodiment, the valve 400 selectively has two configurations. According to a non-limiting embodiment, a first configuration corresponds to a so-called raised configuration in which the valve 400 extends mainly vertically, the second configuration corresponding to a so-called lying configuration in which the valve 400 extends mainly horizontally. Advantageously, the valve 400 comprises at least one hinge element 402. This hinge element 402 comprises an axis of rotation, preferably horizontal. This hinge element 402 advantageously comprises at least one return element configured to hold the valve in the raised configuration when the carriage 1 is not nested with another carriage 1b, preferably is not nested around another of the containing cart 1b.

Still through Figures 56 to 63, it will be noted that the frame 100 comprises covers 35 arranged above the measuring devices 50. These covers 35 are supported on the frame 100 so that when a force having a vertical component s applied to the frame 100 or to the cover 35, this force is transmitted to the supporting structure 200 then to the frame 10 so that this force cannot disturb the measurement device(s) 50, preferably cannot disturb the measurement(s) of weights carried out by the measuring device(s) 50.

Thus, according to the example illustrated in Figures 56 to 63, the carriage 1 comprises at least 4 measuring devices 50. Each arm of the carriage 11, 12 preferably carries two measuring devices 50. These measuring devices 50 will be described more precisely. afterwards.

In Figure 56, the carriage 1 comprises a gripping device 60 and a display device 70 as described previously.

Trolley 1 thus comprises at least one container 40 suspended from frame 100 through four measuring devices 50. According to one embodiment, as mentioned previously, this container 40 comprises two parts, a front part 103 and a rear part 104 The front part 103 comprises a width dimension 103a greater than the width dimension 104a of the rear part 104. The front part 103 of the container 40 comprises the valve 400 described above. The rear part 104 of the container 40 comprises at least one rear wall 403. The front part 103 of the container 40 is suspended from the frame 100 through two measuring devices 50. Indeed, the front part 103 of the container 40 is suspended from the first arm 11 of the carriage 1 by a measuring device 50 through a suspension bar 34, and to the second arm 12 of the carriage 1 by another measuring device 50 through another suspension bar 34. the same for the rear part 104 of the container 40.

Finally, it will be noted in FIG. 56, for example, the presence of a block comprising an electric battery 54 configured to electrically supply all of the electric elements of the trolley 1. This block is advantageously arranged under the container 40 so that the center of gravity is as low as possible.

FIG. 57 is a side view of the carriage 1 illustrated in FIG. 56. The elements previously described are found in this figure. Note in particular the block 54 comprising a coaxial finger 53. This coaxial finger is configured to abut against an abutment carried by the container 40. Thus, the abutment limits the movement and therefore the swinging of the container 40. Preferably, the stop is formed by an opening in which the coaxial finger 53 is inserted. The coaxial finger 53 is configured to bear against the edge of the opening carried by the suspended container 40 so as to limit the swinging of said container 40 suspended .

According to one embodiment, the coaxiality finger 53 can be replaced or comprise an additional measuring device 53. This additional measuring device 53 is intended to support at least part of the container 40 and its contents, and preferably intended to measure the weight of the container 40 and its contents.

Figure 58 is a top view of a carriage 1 as shown in Figures 56 and 57. In this figure it can thus be seen, as indicated above, that the front part 105 of the carriage 1 is narrower than the rear part 106 of the carriage 1 so as to allow said carriage 1 to fit into at least part of another carriage 1b.

Similarly, in this figure, it is noted that the front part 103 of the container 40 is wider than the rear part 104 of the container 40 so as to allow said carriage 1 to fit around at least part of another carriage 1b, preferably to allow the interlocking of the front part 103 of the container 40 of the carriage 1 around the rear part 104 of the container 40 of the other carriage 1b.

FIG. 59 is an enlargement of a measuring device 50 arranged under a cover 35 and between a first part 101 of the frame 100 and a second part 102. The measuring device 50 is connected to at least part of the container 40 by a suspension bar 34. The use of a cover 35 is clever, because it only rests on the frame 100, and is not in direct mechanical contact with the measuring device 50, so that any force applied to the cover 35 and having a vertical component is neither transmitted to the measuring device 50, nor to the container 40, but directly to the frame 100, then to the supporting structure 200 and finally to the chassis 10.

Figure 60 illustrates the same enlargement as Figure 59 with cover 35 removed. We therefore discover the measuring device 50 comprising a force sensor 51. This force sensor 51 is integral with the first part 101 of the frame 100 and the second part 102 of the frame 100. This attachment is provided by attachment bars 55 and by a hook 56 of the force sensor 51. This hook 56 attaches the force sensor 51 to the connection bars 55. This connection is clever, because it prevents any force applied to the frame 100 from disturbing the measurement of the weight of container 40 and its contents. In addition, the introduction of the measuring device 50 into the very structure of the frame 100 allows a consequent saving of space and better ergonomics. This force sensor 51 is also attached to at least part of the container 40 preferably through a suspension bar 34.

According to one embodiment, the frame 100 includes the securing bars 55

Figure 61 is a view following figure 60, in which the force sensor 51 is detached from the frame 100 for the sake of clarity in order to illustrate the mechanical assembly of the measuring device 50 according to a clever embodiment. It is thus noted that the container 40 is suspended from the measuring device 50, in particular from the force sensor 51, by means of the suspension bar 34. The container 40 is thus completely decorrelated from the forces which may or may not be applied to frame 100 of carriage 1.

Advantageously, the frame 100 includes at least one opening 107, which can take the form of a through opening, a recess or a groove. The measuring device 50 is arranged, preferably fully housed, inside the opening 107 of the frame 100.

Figure 62 illustrates a carriage 1a nested around another carriage 1b. As presented previously, the trolley 1a comprises a container 40 having a front part 103 wider than its rear part 104 so as to cooperate with the rear part 104 of another trolley 1b identical to the trolley 1a and thus so as to come s fit around the rear part 103 of the container 40 of the other carriage 1b.

In particular, and in a clever way, the rear part 104 of the container 40 of the other trolley 1b then fits into the front part 103 of the container 40 of the trolley 1a. When the two carriages 1a and 1b are interlocked, the valve 400 of the carriage 1a is swapped in its lying configuration by the rear part 104 of the container 40 of the other carriage 1b. It will also be noted that the rear part 104 of the container of a trolley 1 comprises a rear wall 403.

Figure 63 schematically illustrates a top view of the interlocking of the carriage 1a with the other carriage 1b. Note that the front part 103 of the container 40 of the trolley 1 surrounds at least part of the rear part 104 of the container 40 of the other trolley 1b, and that the front part 105 of the frame 10 of the trolley 1a comes to fit in at least part of the rear part 106 of the frame of the other carriage 1b.

The present invention thus makes it possible to fit together simply, efficiently and reliably two trolleys each equipped with at least one device for measuring the weight of a container and its contents.

In all the preceding embodiments, the terms containers, bins, boxes or receptacles are considered equivalent and can be interchanged.

The invention is not limited to the embodiments described in the non-limiting examples above, but extends to all embodiments falling within the scope of the claims.
