Carriage for supporting and weighing a container

​TECHNICAL FIELD

​The invention relates to the field of transport carts. It finds particular application for dispensing surfaces such as supermarkets. More specifically, the invention relates to the integration of measuring devices within carriages in order to weigh the articles selected by the user and placed in the carriage.

​PRIOR ART

​In a known manner, the supermarkets provide self-checkout devices referred to as automatic cash boxes allowing people in their strokes, once all their strokes are put into the trolley, to take the sum of the sum to be paid and to the settlement of this sum. This includes a step of scanning each item, via an optical reader, and then a step of weighing each selected item.​In particular, this weighing step makes it possible, in particular, to ensure that each article placed by the user in the carriage has indeed been scanned and thus has been counted for its settlement.

​These automatic crates as described are often made available to the users to allow first to limit long and large queues to the cashing of the strokes and secondly increase the number of casks per unit time and therefore increase the productivity of the supermarkets.

​In order to completely eliminate these long and large queues, there are nos days of the carriages having the function of weighing the articles selected by the user by themselves.

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

​In addition, these carriages often have regular malfunctions and often lack precision. As a result, discrepancies are indicated between the articles placed in the carriage and those counted as a result of the scanning step. This situation prevents an attempt to effectively identify a fraud attempt. In contrast, this situation is also delicate in that it can be uncomfortable for the user of good foi.

​Another disadvantage of this type of trolleys is that they are often bulky, making it difficult to store them.

​There is therefore a need to provide a solution to reduce or even eliminate at least some of the above-mentioned disadvantages.

​The present invention aims to meet this need.

​The other objects, features and advantages of the present invention will become apparent upon examining the following description and accompanying drawings. It is understood that other advantages can be incorporated.

​DETAILED DESCRIPTION

​Before initiating a detailed review of embodiments of the invention, following optional features which may optionally be used in combination or alternatively:

​In one example, the carriage includes at least one cover supported by the frame and disposed above the measuring device such that when a force, having a vertical component, is applied by a user to the cover, the vertical component is transmitted from the cover to the frame and then to the frame and then to the ground without being transmitted to the suspension structure. This makes it possible to protect the force sensors from bearing on the frame of a user.

​This allows mechanical isolation of the measurement device relative to the frame.

​In a preferred example, the cover is integrally supported on the frame.

​In one example, the cover is not in mechanical contact with the measurement device.

​In one example, the measurement device is suspended from the frame.

​In one example, the frame includes at least one opening, a groove, or a recess. The measurement device is disposed within the opening. Preferably, the measuring device does not project beyond the opening. Thus, it is possible to optimize the integration of the latter into the frame. The measuring device is thus well protected. Preferably, the frame includes two openings each distributed across a median plane of the carriage. Each arm of the frame has at least one opening.

​In one example, the frame includes a first portion and a second portion, and the opening defines the first and second portions. Thus, the opening and the junction of the first second portions.

​In one example, the measuring device is inserted into a portion of the frame, preferably between two portions of the frame.

​In one embodiment, each arm of the carriage includes at least one measurement device disposed between a first portion of the frame and a second portion of the frame, the first portion of the frame and the second portion of the frame partially defining at least said arm.

​In one example, the chassis has a front portion and a rear portion, the front portion having a first width dimension, the rear portion having a second width dimension, the first width dimension being less than the second width dimension.

​In one example, the container has a front portion and a rear portion, the front portion having a first width dimension, the rear portion having a second width dimension, the first width dimension being greater than the second width dimension.

​In one example, the front portion of the container is configured to surround at least a portion of the rear portion of the container of another carriage in a storage configuration.

​In one example, the container includes at least one valve disposed at the front of the at least one container. Preferably, the valve fully or partially forms a wall of the container. Preferably, said valve is secured to the container through at least one hinge element comprising at least one axis of rotation​, said valve being configured to selectively present a first configuration in which the valve defines a wall of the container and a second configuration in which the valve extends along a wall of the container, the valve being configured to be rotatable about said axis of rotation so as to selectively switch from one configuration to another.​In a non-limiting embodiment, the first configuration corresponds to a prone configuration and the second configuration corresponds to a raised configuration.

​Preferably, in the second configuration, the valve extends mainly along a horizontal plane.

​In one example, the valve is in a supine configuration when another carriage is nested within the carriage.

​In one example, the hinge member includes at least one biasing member configured to hold the valve in a raised configuration when another carriage is not nested within the carriage.

​According to one example, the carriage comprises at least one additional measuring device borne at least in part by the chassis, being intended to measure at least one parameter relating to the weight of the at least one container and being arranged below the container.

​In one example, the container is secured to the carriage, preferably only, through one or more measuring devices.

​In one example, the suspension structure has a height dimension that decreases along a direction corresponding to the direction of engagement of said carriage in another carriage so as to allow at least partially nesting of the carriage in another carriage having a suspension structure identical to the suspension structure of said carriage

​In one example, the frame has a height dimension that decreases along a direction corresponding to the direction of engagement of said carriage in another carriage so as to allow at least partially nesting of the carriage in another carriage having a suspension structure identical to the suspension structure of said carriage

​In one example, the carriage comprises at least one coaxiality finger supported at least in part by the chassis, being configured to engage a stop carried by the container, the cooperation between the coaxiality finger and the stop being intended to limit the swinging of said container. In one example, the stopper is formed by an opening carried by the container. By abutting the edges of said opening, the coaxiality finger limits the swing of said container.

​In one example, the front portion of the chassis is configured to engage at least a portion of the rear portion of the chassis of another cart in a storage configuration.

​In an optional example, the carriage includes a gripping device to be grasped by the user to preferably manually move the carriage.

​In one example, the measurement device is supported entirely by the suspension structure.

​This makes it possible to measure a parameter relating to the weight of the at least one container intended to be suspended by the suspension structure.

​According to one example, the measuring device comprises at least one force sensor for measuring the parameter relating to the weight of the at least one container and the at least one product contained therein, preferably said force sensor comprising a strain gauge. This makes it possible to measure a parameter relating to the weight of the at least one container.

​In one example, the suspension structure has a plurality of receiving zones for suspending at least two and advantageously at least three containers. This allows multiple containers to be suspended according to the needs of the user.

​According to one example, the cooperation of the suspension structure of said carriage with the suspension structure of said other carriage to allow at least partial nesting of said carriage in said other carriage comprises at least one of the following embodiments:

​The suspension structures are movably mounted on the carriage. They are, for example, articulated in rotation about an axis, for example horizontal. In an alternative embodiment, the carriage is slidably mounted on the carriage. The mobility of the suspension structures allows, in the storage configuration, not to impede the engagement of a carriage in another carriage.

​ii. The suspension structures have shapes for engaging a carriage in another carriage.

​In one example, the suspension structure is rotatably hinged to the support structure about an axis parallel to the ground, preferably horizontal. This allows the suspension structure to be lifted to facilitate engagement of the carriage with another carriage having a suspension structure

​identical to the suspension structure of said carriage. As a result, a compact socket is obtained.

​In one example, the suspension structure is configured to have a carrying configuration and a storage configuration different from the carrying configuration, said carrying configuration allowing suspension of the at least one container by the suspension structure in particular when the carriage rolls, in said carrying configuration​, the suspension structure being in contact with a stop carried by the support structure preventing rotation of the suspension structure under the effect of gravity, said storage configuration being configured to allow at least partially nesting of the carriage with another carriage having a suspension structure identical to the suspension structure of said carriage, in the storage configuration, the suspension structure of said carriage being remote from the stop.

​This allows the user to choose the configuration of the trolley according to the use that he wishes to operate.

​In one example, the suspension structure is configured to, in a carrying configuration, extend in a direction parallel to the ground.

​In one example, the suspension structure is mounted in free rotation on the support structure.

​In one example, the carriage includes a ram configured to maintain the suspension structure in a storage configuration at least when the suspension structure does not suspend any container.

​This makes it possible to facilitate the engagement of the carriage with another carriage having a suspension structure identical to the suspension structure of said carriage. As a result, a compact socket is obtained.

​In one example, the suspension structure is shaped so as to have an at least partially serrated upper surface forming said receiving zones. This makes it possible to suspend and stably hold the possible handles or handles of the at least one container on the receiving areas.

​In one example, the suspension structure includes at least one hanger bar shaped to at least partially penetrate the at least one container.

​This facilitates positioning of the at least one container on the suspension structure.

​According to an example, the suspension structure comprises at least a first arm and a second arm extending on either side of said carriage respectively in a first direction and a second direction, the first direction and the second direction being common.

​In one example, the suspension structure has a height dimension that decreases along a direction corresponding to the direction of engagement of said carriage in another carriage so as to allow at least partially nesting of the carriage in another carriage having a suspension structure identical to the suspension structure of said carriage.

​This makes it possible to facilitate the insertion of the carriage into another carriage having a suspension structure identical to the suspension structure of said carriage. As a result, a compact socket is obtained.

​In one example, the first and second arms are shaped so as to each have at least two first portions, for example horizontal extending in two directions parallel to the ground or having a first inclination with respect to the ground.​Furthermore, the first and second arms are shaped so as to each have at least a second portion, for example vertical extending in a direction orthogonal to the ground or having a second inclination with respect to the ground, the second inclination being greater than the first inclination.​The second portion separating the two first portions, so as to allow engagement of said carriage in part at least with at least one other carriage having a suspension structure identical to the suspension structure of said carriage by fitting the suspension structure of said carriage with the suspension structure of said at least one other carriage.

​In one example, the suspension structure has a length dimension l2 and is configured to allow a variation of said length dimension l2. This makes it possible to adapt the length dimension l2 according to the needs of the user. Generally, the lengths are measured in a direction parallel to the preferred direction of advancement of the carriage.

​In one example, the length dimension L2 is greater than 5 cm, preferably 15 cm and is advantageously equal to 25 cm.

​In one example, the arms include telescoping portions each configured to have a deployed configuration of the telescoping portions of the arms and a collapsed configuration of the telescoping portions of the arms, said collapsed configuration allowing said carriage to be nested with at least one other carriage having a suspension structure identical to the suspension structure of said carriage.

​This makes it possible to facilitate the insertion of the carriage into another carriage having a suspension structure identical to the suspension structure of said carriage. As a result, a compact socket is obtained.

​In one example, the suspension structure has a width dimension I2 configured to decrease along a direction corresponding to the direction of engagement of said carriage in another carriage so as to allow at least partially nesting of the carriage in another carriage having an identical suspension structure.

​This makes it possible to facilitate the insertion of the carriage into another trolley having one

​suspension structure identical to the suspension structure of said carriage. As a result, a compact socket is obtained.

​Generally, the widths are measured in a direction perpendicular to the preferred direction of advancement of the carriage.

​In one example, the width dimension I2 is less than 21 cm, preferably 14 cm and is advantageously equal to 7 cm.

​According to an example, the arms of the structure of the suspension are integral with each other by means of at least one telescopic securing portion, said telescopic securing portion being configured to have a deployed configuration, in which the arms are in a position spaced apart from each other, and a collapsed configuration​, in which the arms are in a position close to each other and in which the carriage is capable of being nested with at least one other carriage having a suspension structure identical to the suspension structure of said carriage.

​According to an example, the carriage comprises at least one tray entirely suspended from the support structure by at least one flange, preferably by at least two flanges, advantageously opposite to each other, and at least one flange comprises at least one device for additional measurement of the weight of said suspended bin and of the at least one product intended to be deposited thereon.

​This makes it possible to deposit and weigh heavy products.

​In one example, the suspended bin includes at least one opening configured to at least partially receive at least the hanger bar of at least one other carriage having a hanger bar identical to the hanger bar of the at least one carriage and when the carriage and the other carriage are nested together. This makes it possible to facilitate the insertion of the carriage into another carriage having a suspension structure identical to the suspension structure of said carriage. As a result, a compact socket is obtained.

​In one example, the carriage includes at least one receptacle for receiving at least one product and being supported by the at least one chassis, and the weight of which is measured by the at least one measurement device.

​This makes it possible to deposit and weigh heavy and bulky products.

​In one example, the receptacle has at least one side wall configured to be rotatable about an axis of rotation, preferably parallel to the ground, such that the wall or may pass from a configuration in which the wall is disposed in a first position defining a closed container with the other walls of the receptacle to a configuration in which said wall is disposed in a second position​inclined with respect to the first position about the axis of rotation and allows said carriage to be at least partially nested with at least one other carriage having a receptacle identical to the receptacle of said carriage.

​This makes it possible to facilitate the insertion of the carriage into another carriage having a receptacle identical to the receptacle of said carriage. As a result, a compact socket is obtained.

​In one example, the carriage is configured such that when a force applied by a user on the gripper has a vertical component, this vertical component is transmitted from the gripper to the chassis and then to the ground without being transmitted to the support structure and the suspension structure.​This allows the user to bear on the gripping device to move the carriage while avoiding disturbing the measurement of a parameter relating to the weight of the at least one container and the at least one product contained therein.

​In one example, the carriage includes at least one frame carried by the frame, the frame being configured such that when a force, having a vertical component, is applied by a user to the frame, the vertical component is transmitted from the frame to the chassis and then to the ground without being transmitted to the support structure and the suspension structure.

​This allows the frame to interview access for support by the user on the suspension structure. Thus, the user can bear on the carriage, in particular on the frame by avoiding disturbing the measurement of a parameter relating to the weight of the at least one container and the at least one product contained therein.

​In one example, the frame is configured to define a shell enclosing an internal volume and the receiving areas of the suspension structure are within said internal volume.

​In one example, the frame is remote from the suspension structure.

​In one example, the carriage includes at least one display device, which is configured to display the price of a product at least one parameter relating to the weight is measured by the measurement device.

​This allows the user to track the price of the at least one product to be contained in the at least one container.

​In one example, the suspension structure includes at least two containers, also referred to as boxes or bins, for receiving the at least one container and the product contained therein.

​In one example, the suspension structure includes at least one container having at least two docking areas for suspending an additional container.

​In one example, the suspension structure includes at least a first container and a second container, at least one of which is configured to translate relative to the frame such that, in a retracted configuration of the carriage, the first container is at least partially received in the second container. This embodiment is combinable with all the features and all the technical effects mentioned above.

​In one example, the carriage is configured such that the first container is housed entirely within the second container in a retracted configuration, that is, when the carriage is at least partially nested within the other carriage.

​In one example, the carriage is configured to have a deployed configuration of the containers, wherein the passage from the retracted configuration to the deployed configuration is performed by gravity.

​In one example, the at least one container is slidably mounted to the suspension structure to translate relative to the frame, the sliding direction being inclined so as to translate the at least one container by gravity.

​In one example, the carriage is configured to have a deployed configuration of the containers and the passage from the deployed configuration to the retracted configuration is accomplished by engaging the carriage in another carriage.

​In one example, the carriage includes at least three containers, each container slidably mounted to the suspension structure. Preferably, so as to slide when the carriage is nested in another carriage and/or when the carriage is de-nested with respect to another carriage.

​In one example, the one or more containers are rigid, that is, they are not manually deformable.

​In one example, the container is deformable and deforms when the carriage is nested within another carriage. The container is flexible or crumable. In one example, the container has preferred deformation zones. In one example, the container transitions from a retracted configuration to a gravity-deployed configuration, the container having at least one of its ends that is slidable along the suspension structure, being driven by its point.​In one example, the container is formed at least in part of fabric or fabric.

​In one example, the carriage includes at least one container in which at least one product is to be placed.

​In one example, the at least one container is rigid, that is, it is not manually deformable.

​According to an example, the suspension structure, the at least one container and the chassis of said carriage are shaped to cooperate with the suspension structure, the at least one container and the chassis of another trolley so as to allow 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, of the at least one container and the chassis of said carriage with the suspension structure​, the at least one container and the chassis of said other carriage.

​According to an example, the suspension structure, the at least one container and the chassis of said carriage being shaped to cooperate with the suspension structure, the at least one container and the chassis of another trolley so as to allow 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, of the at least one container and the chassis of said other carriage with the suspension structure​, the at least one container and the chassis of said carriage.

​It is specified that, in the context of the present invention, the same is used as, for example, a first element identical to a second element that means that these two elements have structurally and/or functionally similar characteristics. In all embodiments which are described below, the terms, containers, boxes, or receptacles are considered equivalent and may be substituted with one another.

​We have now described the invention according to its many embodiments through FIGS. 1 to 32.

​The present invention relates to a trolley 1, for example for a supermarket as described later. The carriage 1 is a transport carriage, thereby transporting loads. By way of non-limiting example, these loads are shopping items arranged in a container.

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

​FIGS. 1 to 1 represent the carriage 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.

​In one embodiment, the container may be a suspended bin 40 as shown in FIGS. 1 to 9 for example. In another embodiment compatible with the foregoing, the container may also be a bag-like bag 90, a bottom bag or a rigid bag as shown in FIGS. 8 and 9 for example. Generally, the at least one container (40, 90) may be any element operable to contain the at least one product.​The measuring device 50 May include at least one force sensor 51, which may also be referred to as a force sensor, shown in FIG. 1 for example. The measurement device is configured to measure a parameter relating to the weight of the at least one container (40, 90) and the at least one product contained therein. For example, the measurement device 50 May be configured to form a cantilever weight sensor.

​In one example, the force sensor 51 includes a strain gauge or strain gauge. The force sensor 51 May be a so-called S-shaped single point sensor. 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 contained therein.​In a preferred case where the at least one container (40, 90) has a negligible weight, the measurement 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 carriage 1 capable of subtracting the weight of the at least one container (40, 90) from the measured total weight in order to obtain only the measurement of the weight of the at least one product.

​The carriage 1 comprises at least one chassis 10. The term "chassis" means a rigid frame intended to support other elements of the carriage 1. The chassis 10 is supported by at least three support members 20 configured to support the carriage 1 on a ground in an isostatic manner. At least two of the at least three support members 20 each comprise at least one rolling device, preferably the at least three support members 20 comprise at least one rolling device.​The rolling device preferably comprises at least one wheel. In 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 to increase the workability of the trolley. In another example, the rolling device is a track. The at least three support members 20 are present in all embodiments described by the invention.​In addition, the carriage 1 comprises a support structure 200 supported by the chassis 10. By the support structure 10, any element or set of elements exerting a support function is meant. By way of example, the support structure 200 May manifest in the form of a frame, or vertical beams or even columns.

​The support structure 200 supports a suspension structure 30. By the suspension structure an is meant any element or set of elements exerting a suspension function. By way of non-limiting example, the suspension structure 30 May be one of a bar, a platform, a hook, a handle, a portion of a frame. The suspension structure 30 has accommodation areas 31.​The docking areas 31 are configured to suspend the at least one container (40, 90) in which the at least one product is to be placed.

​Preferably, the measurement 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 the at least one product via the measurement performed by the measurement device 50.
