Definitions
- the logistics module may be, for example, of the container type for transporting goods, in particular a "roll" type container.
- the logistics module can therefore be used, for example, to transport goods to stores in order to supply them.
- Containers are commonly used to transport goods to stores to supply them.
- these containers are filled with goods to be transported.
- the containers filled with goods are placed in a loading area of a transport vehicle, typically a truck.
- the trucks When the truck has arrived at a destination store, the containers containing the goods intended for this store are removed from the loading area of the truck.
- the containers still filled with goods can be temporarily stored in a warehouse in the store. Then, one or more of these containers can be removed from the warehouse premises to be transported to shelves to be filled with the goods they contain.
- the ergonomics aspect occurs when loading and unloading containers. These operations are generally carried out manually by individuals, operators. When goods must be placed at a relatively low height, for example, close to the ground, the operator may be required to bend over. When goods must be placed at a relatively high height, the operator may be required to raise his arms above his shoulders. These body movements are tiring and wear out the body, which can lead to medical problems.
- the loading space is not necessarily fully used, or even almost fully used. If the containers are significantly lower than the loading space, an upper part of the loading space remains empty, unused. In practice, this is generally the case, mainly because of the following.
- the height of the loading space of a truck is typically between 2.20 m and 2.50 m.
- the height of "roll" type containers is typically around 1.80 m for ergonomic reasons. Indeed, if the height of the container is too great in relation to the height of an operator's arms, the operator would have difficulty filling the container completely. For example, he would have to raise his arms excessively or resort to a stepladder or similar tool in order to fill an upper part of the container.
- Patent document FR2899782 addresses the ergonomic aspect of a shelving storage device.
- This device comprises a parallelepiped frame that houses a lower rigid box and an upper deformable box.
- Each of these boxes comprises at least one shelf.
- the upper deformable box In the absence of any product stored in the boxes, the upper deformable box is in the retracted position. When products are gradually loaded into the lower rigid box, the latter gradually slides downwards. The upper deformable box then gradually moves to the deployed position. Thus, a shelf of the upper deformable box then becomes accessible.
- a logistics module comprising: a frame, an upper shelf slidably coupled to the frame, a lower shelf slidably coupled to the frame, a set of stop members defining a lower end-of-travel position and an upper end-of-travel position between which the upper shelf can slide, and defining an upper end-of-travel position and a lower end-of-travel position between which the lower shelf can slide, the upper end-of-travel position of the lower shelf being lower than the lower end-of-travel position of the upper shelf, a coupling mechanism capable of sliding the lower shelf downwards and the upper shelf upwards when a load supported by the lower shelf exceeds a tilting threshold relative to a load supported by the upper shelf and, conversely, capable of sliding the lower shelf upwards and the upper shelf downwards when the load supported by the lower shelf falls below a tilting threshold relative to the load supported by the upper shelf.
- an operator can start stacking goods on the upper shelf, which can be at an ergonomic height.
- the operator can thus load the upper shelf with goods up to a height that is still ergonomic.
- the operator can start stacking goods on the lower shelf, which can also be at an ergonomic height.
- the lower shelf thus supports an increasingly heavier load as it is loaded.
- the load supported by the lower shelf exceeds the tipping threshold compared to the load supported by the upper shelf. This causes a mechanical tilting movement: the lower shelf slides downwards, the upper shelf slides upwards.
- the fact that the upper shelf slides upwards has two consequences. A first consequence is that the goods on this shelf are raised to a greater height at which the operator would not necessarily have been able to stack the goods ergonomically. The second consequence is that space is freed up in the logistics module at the ergonomic height at which the upper shelf was located when it was loaded. This freed up space is thus once again available for loading goods into the logistics module.
- the fact that the lower shelf slides downwards has a similar consequence: more space is available for storing goods on the lower shelf.
- a new loading height is available for the operator which can also be ergonomic.
- a reverse pattern applies. An operator can start removing goods stacked on the lower shelf.
- the goods that are on top of this stack can be at an ergonomic height.
- the lower shelf supports a progressively lighter load as it is unloaded. At a certain point, the load supported by the lower shelf falls below the tipping threshold compared to the load supported by the upper shelf. This results in a mechanical tilting movement that is the opposite of that mentioned above: the lower shelf slides down and the upper shelf slides up.
- the fact that the lower shelf slides upwards has two consequences. A first consequence is that the goods still present on this shelf are raised to a height that can be more ergonomic for removing them. The second consequence is that the goods stacked on the upper shelf are lowered to a height that can also be ergonomic for removing them. The operator can therefore continue to ergonomically remove all these goods still remaining in the logistics module.
- the logistics module defined above can therefore be efficiently filled with goods up to a height only slightly lower than that of a loading space, while still allowing ergonomic loading and unloading of the goods. Consequently, the logistics module enables a high loading rate of the loading space to be achieved in an ergonomic manner. Furthermore, the ergonomic loading and unloading does not require any special tools that entail additional costs.
- the logistics module defined above thus enables the transport of goods in an ergonomic and economical manner.
- the lower end position of the upper shelf is at a height between 1.00 m and 1.50 m.
- the upper end position of the lower shelf is at a height between 1.40 m and 0.50 m.
- the upper end position of the upper shelf is at a height between 1.50 m and 2.50 m.
- At least one of the stop members is attached to the frame. In one embodiment, at least one of the stop members comprises a damping device capable of damping an arrival of one of the following shelves, the upper shelf and the lower shelf, at its lower end-of-travel position.
- the upper shelf, the lower shelf, and the coupling mechanism are arranged such that the upper shelf is in its lower end of travel position and the lower shelf is in its upper end of travel position when there is no load on the lower shelf.
- the logistics module includes a visual indicator located above the lower end position of the upper shelf, the visual indicator indicating a maximum fill level of the upper shelf.
- the logistics module comprises: an openable face through which the upper shelf can be loaded, and a fall protection flap capable of covering at least a portion of the openable face of the logistics module.
- the fall arrester covers a portion of the openable face between the upper end-of-travel position of the upper shelf and an upper edge of the openable face.
- the fall arrester includes the visual indicator.
- the frame includes a pair of guide rails adapted to jointly retain the upper shelf and the lower shelf in a slidable manner.
- the coupling mechanism includes a link between the upper shelf and the lower shelf and a pulley through which the link passes.
- the upper shelf has a greater weight than the lower shelf such that the upper shelf is in its lower end of travel position and the lower shelf is in its upper end of travel position when there is no load on the lower shelf.
- the upper shelf includes a ballast member.
- the upper shelf and the lower shelf are foldable.
- the logistics module is in the form of a cart for transporting goods.

- Figure 2 is a schematic perspective view of a basic structure that forms part of the cart.
- Figure 3 is a schematic perspective view of an upper portion of the base structure after removal of a lintel.
- Figure 4 is a schematic perspective view of a small portion of the basic structure near a shelf.
- Figure 5 is a schematic perspective view of the carriage at a first intermediate stage of a loading operation.
- Figure 6 is a schematic perspective view of the carriage in a second intermediate stage of the loading operation.
- Figure 7 is a schematic perspective view of the carriage in a third intermediate stage of the loading operation.
- Figure 8 is a schematic perspective view of the carriage in a final stage of the loading operation.
- Figure 9 is a schematic perspective view of the trolley with a fall-prevention flap covering an upper portion of an open face thereof.
- Figure 10 is a schematic perspective view of an alternative basic structure.
- FIG 1 schematically illustrates an embodiment of a logistics module 100 in the form of a trolley.
- Figure 1 presents a schematic perspective view of this embodiment 100 which will hereinafter be referred to as the trolley 100 for the sake of ease of reading.
- the trolley 100 is particularly suitable for transporting goods, for example, from a logistics platform to a store, as well as to move goods to shelves within the store for filling.
- the trolley 100 may have the following dimensions: a width between 60 cm and 80 cm, a depth also between 60 cm and 80 cm, and a height between 200 cm and 250 cm.
- the height of the trolley 100 is preferably only slightly lower than that of a loading space of a transport vehicle generally used for transporting goods. This makes it possible to achieve a filling rate of the loading space sufficiently close to the optimum, i.e. close to 100%.
- the height of the trolley 100 must also allow it to pass through doors of standard dimensions of logistics warehouses and stores.
- the trolley 100 comprises a frame 101 and two shelves 102, 103 slidably coupled to the frame 101.
- the two shelves 102, 103 can thus each slide vertically, that is, up and down. Notwithstanding their ability to slide, one of the two shelves 102 is always the furthest from the ground. This shelf will therefore be designated the upper shelf 102.
- the other shelf 103 which is always the closest to the ground, will be designated the lower shelf 103.
- a coupling mechanism 104 mechanically connects the two shelves 102, 103 to each other. This coupling mechanism 104 will be described in more detail later in this description.
- the frame 101, the two shelves 102, 103 and the coupling mechanism 104 together constitute a basic structure which will also be described in more detail later.
- the trolley 100 comprises three vertical walls 105, 106, 107 mounted on a base 108 provided with casters. One of the three vertical walls 105 adjoins the frame 101. This vertical wall 105 will be designated the bottom wall 105 for ease of reading.
- the other two vertical walls 106, 107 cover two lateral sides of the trolley 100 and will jointly be designated the two side panels 106, 107.
- the two side panels 106, 107 are each coupled to the frame 101 by hinges.
- the two side panels 106, 107 are each in the form of a grid.
- One face 109 of the trolley 100 has no wall; this face 109 is therefore open. The trolley 100 can therefore be loaded and unloaded through this open face 109.
- Figure 1 illustrates the trolley 100 in an extended state.
- the trolley 100 can be folded by folding the two shelves 102, 103 against the frame 101 so that both are flush with the back wall 105. Then, the two side panels 106, 107 can be folded against the frame 101 so that both are also flush with the back wall 105. Once folded, the trolley 100 can be stored with other similar trolleys, also folded, without taking up too much space. To do this, the folded carriage 100 can engage in another similar carriage, also folded, at the base 108.
- the carriage 100 comprises two visual indicators 110, 111 in this embodiment.
- One visual indicator 110 is located on an upright of one of the two side panels 106, delimiting the open face 109 of the carriage 100.
- the other visual indicator 111 is located on an upright of the other of the two side panels 107 also delimiting the open face 109 of the carriage 100.
- These visual indicators 110, 111 have a function which will be described later.
- the visual indicators 110, 111 may each be in the form of, for example, a piece of contrasting color fixed to the upright in question, or applied thereto with paint or a marker.
- Figure 2 schematically illustrates the basic structure of the cart 100 mentioned in the above.
- Figure 2 shows a schematic perspective view of the basic structure.
- the frame 101 comprises a pair of guide rails 201, 202.
- This pair of guide rails 201, 202 jointly holds the upper shelf 102 and the lower shelf 103 in a sliding manner.
- One of the guide rails 201 will be referred to as the left guide rail 201 in the following for ease of reading.
- the other guide rail 202 will be referred to as the right guide rail 202.
- the upper shelf 102 comprises a support 203 provided with a pair of pads 204, 205. One of these pads 204 is engaged in the left guide rail 201, the other pad 205 is engaged in the right guide rail 202.
- a carrier plate 206 which forms the main part of the upper shelf 102, is rotatably fixed to the support 203 provided with the pair of pads 204, 205.
- the preceding remarks also apply to the lower shelf 103, which is of similar construction.
- the coupling mechanism 104 is partially visible in FIG. 2.
- a lintel 207 hides a portion of the coupling mechanism 104 which will be described later.
- the coupling mechanism 104 includes a pair of cables 208, 209.
- One of these cables 208 is located near the left guide rail 201. This cable will be referred to as the left cable 208 in the following.
- the other cable 209 is located near the right guide rail 202. This other cable will be referred to as the right cable 209 in the following.
- One end of the left cable 208 is fixed to the upper shelf 102 and, more precisely, to the support 203 thereof provided with the pair of pads 204, 205. Another end of the left cable 208 is fixed to the lower shelf 103 and, more precisely, also to the support thereof provided with the pair of pads.
- one end of the straight cable 209 is fixed to the upper shelf 102, while another end of the straight cable 209 is fixed to the lower shelf 103.
- the left cable 208 and the right cable 209 each have a length that is substantially identical. This length will be referred to hereinafter as the cable length.
- the cable length determines a position of the upper shelf 102 relative to that of the lower shelf 103, and vice versa. Therefore, when the upper shelf 102 is at a height from the ground, the lower shelf 103 is at a height from the ground that is fixed by this relationship, and vice versa. This relationship between the position of the upper shelf 102 and that of the lower shelf 103 will be discussed in more detail later.
- the base structure comprises two stop members 210, 211.
- One stop member 210 is located furthest from the ground and is located between the upper shelf 102 and the lower shelf 103. This stop member 210 will be referred to as the upper stop member 210.
- the other stop member 211 is located closest to the ground and is located below the lower shelf 103. This stop member 211 will be referred to as the lower stop member 211.
- the two stop members 210, 211 each comprise a cross member extending between the guide rails 201, 202.
- the upper stop member 210 defines a lower end-of-travel position of the upper shelf 102. This end-of-travel position may be at a height between, for example, 1.00 m and 1.50 m from the ground and, more specifically, between 1.20 m and 1.50 m. To achieve this, the upper stop member 210 may be positioned at a height from the ground similar to, or slightly below, the end-of-travel position in question.
- the upper stop member 210 also defines an upper end-of-travel position of the lower shelf 103. This is due to the relationship between the position of the upper shelf 102 and that of the lower shelf 103 discussed in the foregoing.
- the upper end position of the lower shelf 103 may be at a height between, for example, 1.40 m and 0.50 m from the ground and, more specifically, between 1.20 m and 0.70 m.
- the lower stop member 211 defines a lower end-of-travel position of the lower shelf 103. This end-of-travel position may be located near the ground, slightly above the base 108 of the carriage 100. To do this, the upper stop member 210 may be positioned at a height near the base 108 of the carriage 100 illustrated in FIG. 1. An element of the base 108 may also constitute the lower stop member 211.
- the lower stop member 211 also defines an upper end-of-travel position of the upper shelf 102. This is also due to the relationship between the position of the upper shelf 102 and that of the lower shelf 103 discussed in the foregoing.
- the upper end-of-travel position of the upper shelf 102 may be at a height between, for example, 1.50 m and 2.50 m from the ground and, more specifically, between 1.80 m and 2.30 m.
- the upper stop member 210 and the lower stop member 210 therefore define two sliding ranges: an upper sliding range for the upper shelf 102 and a lower sliding range for the lower shelf 103.
- the upper sliding range is located between the lower end-of-travel position and the upper end-of-travel position of the upper shelf 102, respectively defined by the upper stop member 211 and the lower stop member 210.
- the lower sliding range is between the upper end-of-travel position and the lower end-of-travel position of the lower shelf 103 respectively defined by the upper stop member 210 and the lower stop member.
- the upper end-of-travel position of the lower shelf 103 is lower than the lower end-of-travel position of the upper shelf 102. That is, the upper sliding range and the lower sliding range do not overlap.
- Figure 3 schematically illustrates an upper portion of the base structure in which the lintel 207 indicated in Figure 2 has been omitted.
- Figure 3 presents a schematic perspective view of the upper portion of the base structure.
- the upper part of the base structure comprises a pair of pulleys 301, 302 which are part of the coupling mechanism 104 shown in FIG. 1.
- the left cable 208 passes through one of the pulleys 301.
- This pulley 301 will be referred to hereinafter as the left pulley 301.
- the right cable 209 passes through the other pulley 302 which will be referred to hereinafter as the right pulley 302.
- the left pulley 301 and the right pulley 302 were not visible in FIG. 2 due to the presence of the lintel 207.
- pulleys 301, 302 can be fixed to the lintel 207 which is located between the guide rails 201, 202 on an upper part thereof.
- the left pulley 301 and the right pulley 302 each have a height from the ground which is substantially identical. This height will hereinafter be referred to as the pulley height.
- the pulley height and the cable length determine the relationship between the position of the upper shelf 102 and that of the lower shelf 103 discussed in the foregoing. Specifically, according to this relationship, the sum of the height of the upper shelf 102 relative to the ground and that of the lower shelf 103 is equal to twice the pulley height minus the cable length. Consequently, the height of the upper shelf 102 relative to the ground is equal to twice the pulley height minus the cable length minus the height of the lower shelf 103. Conversely, the height of the lower shelf 103 relative to the ground is equal to twice the pulley height minus the cable length minus the height of the upper shelf 102.
- the pulley height and the cable length are parameters making it possible to achieve a satisfactory degree of ergonomics. The same applies to the height of the upper stop member 210 and that of the lower stop member 211.
- the upper shelf 102 is in its lower end-of-travel position in the absence of a load on the lower shelf 103, as illustrated in FIG. 1, FIG. 2 and FIG. 3.
- the lower shelf 103 is in its upper end-of-travel position in the absence of a load on the lower shelf 103, as illustrated in FIG. 1 and FIG. 2.
- the upper shelf 102 may have a weight greater than that of the lower shelf 103.
- the upper shelf 102 may comprise a ballast member so that its weight is greater than that of the lower shelf 103.
- Figure 4 schematically illustrates a small portion of the base structure in the vicinity of the upper shelf 203.
- Figure 4 presents a schematic perspective view of this portion.
- the upper stop member 210 is partially visible in Figure 4 enlarged compared to Figures 1 to 3.
- the upper stop member 210 comprises a damping device 401.
- the damping device 401 is in the form of a conical cylindrical part with a rounded head comprising flexible material such as rubber or elastomer.
- a lower edge of the support 203 of the upper shelf 102 can abut against this flexible part.
- FIGs 5 to 8 schematically illustrate different stages of a loading operation of the cart 100.
- Each of these figures presents a schematic perspective view of the cart 100 with goods that have been placed in the cart 100.
- the loading operation can start from the empty cart 100 illustrated in Figure 1.
- the upper shelf 102 is then at its lower end-of-travel position while the lower shelf 103 is at its upper end-of-travel position.
- an operator can begin stacking goods on the upper shelf 102.
- the upper shelf 102 is located at an ergonomic height. The operator can thus relatively easily begin stacking the goods on the upper shelf.
- the upper shelf 102 remains at its lower end-of-travel position while the goods are stacked thereon.
- the operator may continue to stack the goods on the upper shelf 102 to a height that is still ergonomic. However, the operator may stop stacking the goods on the upper shelf when they reach a level close to the level where the visual indicators 110, 111 shown in the foregoing with reference to FIG. 1 are located.
- Figure 5 schematically illustrates a first intermediate stage of the loading operation.
- the operator has finished stacking the goods on the upper shelf 102 which will then no longer receive goods during the loading operation in question.
- the upper shelf 102 is still at its lower end-of-travel position at this stage.
- the lower shelf 103 is at its upper end-of-travel position.
- the operator can now begin stacking goods on the lower shelf 103.
- the lower shelf 103 is also at an ergonomic height. The operator can thus relatively easily begin stacking the goods on the lower shelf 103.
- Figure 6 schematically illustrates a second intermediate stage of the loading operation. At this stage, some goods have been placed on the lower shelf 103. These goods constitute a load supported by the lower shelf
- Figure 7 schematically illustrates a third intermediate stage of the loading operation.
- the load supported by the lower shelf exceeds a tipping threshold relative to the load supported by the upper shelf. This results in a mechanical tilting motion: the upper shelf 102 slides upwards and the lower shelf 103 slides downwards.
- the shelf upper 102 has a higher position relative to its lower end position without having yet reached its upper end position.
- the lower shelf 103 has a lower position relative to its upper end-of-travel position without having yet reached its lower end-of-travel position.
- the upper shelf 102 and the lower shelf 103 are thus at intermediate positions.
- the tipping threshold in question concerning the load supported by the lower shelf 103 relative to that supported by the upper shelf 102 corresponds substantially to a ratio slightly greater than 1:1 due to a difference in weight between the upper shelf 102 and the lower shelf 103.
- the upper shelf 102 is heavier than the lower shelf 103.
- the difference in weight means that, in this embodiment, in the absence of a load on the lower shelf 103, the upper shelf 102 is at its lower end-of-travel position and, conversely, the lower shelf 103 is at its upper end-of-travel position.
- Figure 8 schematically illustrates a final stage of the loading operation.
- the operator has finished stacking the goods on the lower shelf 103.
- the trolley 100 is thus almost completely filled with goods as illustrated in Figure 8.
- the upper shelf 102 is then at its upper end-of-travel position.
- the lower shelf 103 is at its lower end-of-travel position.
- An operator can start to remove goods stacked on the lower shelf 103.
- the goods that are at the top of this stack can be at an ergonomic height.
- the lower shelf 103 supports a progressively lighter load as it is unloaded. At a given moment, the load supported by the lower shelf 103 drops below a tipping threshold relative to the load supported by the upper shelf 102. This causes two effects: the lower shelf 103 slides upwards and the upper shelf 102 slides downwards.
- the fact that the lower shelf 103 slides upwards has two consequences. A first consequence is that the goods still present on this shelf are raised to a height that can be more ergonomic for removing them. The second consequence is that the goods stacked on the upper shelf 102 are lowered to a height that can also be ergonomic for removing them. The operator can therefore continue to ergonomically remove all these goods still remaining in the trolley 100.
- the trolley 100 presented in the foregoing by way of illustration can thus be efficiently filled with goods up to a height only slightly lower than that of a loading space, while allowing ergonomic loading and unloading of the goods. Consequently, the trolley 100 makes it possible to achieve a high loading rate of the loading space in an ergonomic manner. Furthermore, the ergonomic loading and unloading does not require special tools leading to additional costs.
- the trolley 100 defined in the foregoing thus enables the transport of goods in an ergonomic and economical manner.
- FIG 9 schematically illustrates a completed version 900 of the trolley 100 illustrated in Figure 1.
- Figure 9 presents a schematic perspective view of this completed version 900.
- the completed version 900 corresponds to the trolley 100 illustrated in Figure 1 to which an anti-fall flap 901 has been added.
- the anti-fall flap 901 covers an upper portion of the open face 109 of the trolley 100. More specifically, this upper portion is located substantially between the upper end-of-travel position of the upper shelf 102 and an upper edge of the open face 109.
- the anti-fall flap 901 thus makes it possible to prevent the goods stacked on the upper shelf 102 fall from the trolley 100. This risk of falling occurs in particular when the trolley 100 is jolted, for example when the trolley 100 is moved or when the trolley 100 is transported in a vehicle.
- the anti-fall flap 901 may constitute a visual indicator which replaces the two visual indicators 110, 111 present on the carriage 100 illustrated in FIG. 1. More specifically, a lower edge of the anti-fall flap 901 may be located at the same level as the two visual indicators 110, 111. The same may apply to a pair of lower attachments of the anti-fall flap 901, one of which is connected to the upright of one of the two side panels 106, the other lower attachment being connected to the other side panel 107.
- the anti-fall flap 901 can be permanently attached to the trolley 100. There is no need to manipulate the anti-fall flap 901 in order to allow loading or unloading. Indeed, the goods present on the upper shelf 102 are accessible when the latter is in its lower end-of-travel position.
- the trolley 100 can comprise one or more other anti-fall flaps in addition to the anti-fall flap 901 illustrated in FIG. 9. Such an additional anti-fall flap can cover another part of the open face 109 of the trolley 100 in order to prevent goods stacked on the lower shelf 103 from falling from the trolley 100.
- Figure 10 schematically illustrates an alternative base structure that can replace the base structure presented in the foregoing and illustrated in Figure 2.
- the alternative base structure also comprises a frame 1001, an upper shelf 1002 and a lower shelf 1003.
- the alternative base structure comprises an alternative coupling mechanism 1004, different from that of the base structure presented in the foregoing.
- the alternative coupling mechanism 1004 comprises articulated links 1005, 1006, 1007 which form a pantograph-type system. This alternative coupling mechanism 1004 can have a similar, or even identical, operation to that of the coupling mechanism 104 presented in the foregoing.
- the alternative basic structure illustrated in Figure 10 shows that there are different coupling mechanisms for transmitting motion in reverse.
- Other mechanisms may include, for example, gears, sprockets, chains, sprocket wheels, sprocket bars, or any combination thereof.
- a coupling mechanism may also incorporate a differential, in the form of, for example, a rack-and-pinion mechanism, which causes there to be some relationship between a motion of the upper shelf and that of the lower shelf which is not necessarily equal to one (1:1).
- the tipping threshold concerning the load supported by the lower shelf relative to that supported by the upper shelf may correspond to a ratio quite different from 1:1.
- the ratio which causes a tipping movement may be 1:2 or 2:1, or any other ratio which is not necessarily expressed by integers.
- the invention can be implemented in many types of products and methods relating to logistics. As an illustration, an implementation has been described which concerns a trolley. Other implementations may concern other types of logistics modules.
- the invention can be implemented in a container, or any other module capable of accommodating goods, not necessarily being equipped with casters.
- a logistics module in accordance with the invention can comprise several open faces instead of just one, as in the case of the trolley presented as an illustration in the foregoing.
- the invention can be implemented in a "roll" type container having four vertical faces, two of which are opposite each other and are open and two others, also opposite each other, are formed by side walls.
- the frame and the coupling mechanism of the shelves could be integrated into one of the two side walls or into both side walls with a section in each side wall.
- the logistics module in the form of a cart comprises two shelves.
- a logistics module may comprise more than two shelves.
- a logistics module may comprise one or more stationary shelves in addition to a sliding upper shelf and a sliding lower shelf.
- a stationary shelf may be added between the upper shelf 102 and the lower shelf 103.
- This stationary shelf could, moreover, constitute a stop member and thus replace the upper stop member 210.
- a set of lower shelves could be rigidly linked together and connected by a coupling mechanism to an upper shelf according to the principle and the modalities already explained previously. That is to say, referring to the trolley 100 illustrated in figure 1, such a set of shelves could replace the lower shelf 103, or replace the upper shelf 102.
- a logistics module according to the invention may comprise a spring system, or based on other elastically deformable members, arranged so that the lower shelf gradually slides downwards when the load supported by it has exceeded the tipping threshold relative to the load supported by the upper shelf. In a reciprocal manner, the upper shelf will then gradually slide upwards. Such a system could also ensure a gradual tipping movement in the opposite direction.
- a logistics module may comprise one or more members for adjusting the tilting threshold at which a tilting movement occurs.
- a member may act as a brake in a track in which the shelves in question slide.
- such a member may be in the form of a rubber or elastomer part, capable of coming into contact with at least one of the pads 204 or 205 of the upper shelf 102 or those of the lower shelf 103. This contact may occur on one or more defined portions of the upper sliding range and the lower sliding range. These portions may be near the end-of-travel positions. This makes it possible to brake a tilting movement over all or part of the sliding range in question and also to adjust the tilting threshold.
- an adjustment member may be in the form of a magnetic element added to, for example, a stop member.
- the magnetic element may exert a force on one of the shelves by magnetic attraction if the shelf is made of a material sensitive to magnetic attraction. This makes it possible to retain a movement of the shelf affected by this magnetic attraction and therefore to be able to adjust one of the tilting thresholds.
- Such members therefore make it possible to obtain two very distinct tipping thresholds. That is to say, the tipping threshold at which a tipping movement in one direction occurs may be significantly different from the tipping threshold at which a tipping movement in the opposite direction occurs.
- An operator could adjust one or the other tipping threshold by modifying, for example, the position of a member or a force that it exerts. It may also be possible to define loading positions intermediates for the shelves between their lower and upper end-of-travel positions defined by the stop members.
- a stop member is attached to the frame and, more specifically, in the form of a cross member between the slide guides.
- a stop member may be present in the coupling mechanism.
- these cables 208, 209 may each be provided with a pair of stop members defining the upper sliding range and the lower sliding range.
- Such a stop member may, for example, for example, constitute a thickening on one or the other cable.
- a logistics module according to the invention may comprise one or more safety devices in order to prevent possible accidents that may occur during its use.
- An accident may occur when the tipping threshold is reached during loading or unloading of the module, causing movement of the shelves.
- an accident may occur if at that moment a part of the body of an operator or another person, such as his head or one of his hands, is in the module and is struck by a moving shelf.
- a safety device comprises one or more plates mounted against one or more walls in the form of a grid.
- a plate may be transparent so that the interior of the module remains clearly visible through the grid.
- the plate may be, for example, made of acrylic glass.
- the plate prevents a hand or finger from passing through the grid and thus prevents the hand or finger from being inside the module. Thus, the plate prevents the risk of the hand or finger being trapped between an element of the grid and a shelf that may move.
- the plate may be mounted on the inside. The plate then prevents part of a good on a shelf from entering a mesh of the grid. This prevents a movement of the shelf from being blocked or the good from being damaged, which could occur when part of the latter is located in a mesh of the grid.
- a safety device comprises a safety stop member and a mechanism operable to bypass the safety stop member.
- the safety stop member may be arranged so that a shelf set in motion after exceeding the tipping threshold can only perform a limited movement, for example of a few centimetres or a few tens of centimetres. This limited movement reduces the risk of an accident and, in addition, warns an operator that the tipping threshold has been reached and exceeded. The operator can then actuate the actuable mechanism to bypass the safety stop member. The shelf can then start moving again to reach its end-of-travel position. The operator could accompany this movement safely by the actuable mechanism.
- the stop member may be an elongated element projecting from a guide rail such as, for example, the left guide rail 201 or the right guide rail 202 of the logistics module 100 described in the foregoing by way of illustration with reference to the drawings.
- the actuable mechanism for bypassing this safety stop member may comprise a removable finger mounted on a shelf. This removable finger may have a default safety position and a movement release position. In the default safety position, the removable finger may come into contact with the safety stop member. The removable finger then blocks the shelf, preventing it from continuing its movement after a short initial movement following the exceeding of the tilting threshold. By actuating the actuable mechanism, the removable finger is released so that it is no longer in blocking contact with the safety stop member.
- the movable finger then reaches the movement release position allowing the shelf to continue its movement to reach its end-of-travel position.
- the actuable mechanism may comprise, for example, a handle mounted on the shelf and a connecting rod disposed between the handle and the movable finger.
