- This geometry in three portions is systematic in the field of storage systems comprising racks, and served by a transport system comprising automatically guided vehicles, the system being capable of picking up and depositing articles in said racks.
- storage systems are called ASRS according to the Anglo-Saxon acronym “Automated Storage and Retrieval System”.
- each bracket is formed by a shaped sheet metal, in one piece, the section of which consists of the three aforementioned portions, serving respectively for fixing the bracket, to the centering the load, and finally supporting the centered load.

Such sizing in thickness meeting these specifications results in a square linear density greater than or equal to 1.8 kg/m typically between 1.8 kg/m and 2.4 kg/m in the direction , longitudinal of the square. According to the observations of the inventors, these brackets can represent almost up to half the weight of the storage rack (ie comprising the vertical structure with the vertical uprights, the bracing devices and said brackets).

- stop means B3, B4 may include:
- first stop B3 formed by a tongue of the metal sheet, projecting from the connecting and centering portion 3 via a folding/bending line, between the first stop B3 and the connecting and centering portion 3,
- a second stop B4 formed by a tongue of the metal sheet, projecting from the support portion 4 via a folding/bending line, extending between the second stop B4 and the portion.
- the folding/bending lines between the first stop B3 and the connecting and centering portion 3, or between the second stop B4 and the support portion 4 are typically oriented perpendicular to the direction X1, longitudinal of the interface 1.
- the tongue forming the first stop B3 and the tongue forming the second stop B4 can have two portions of the tongues, overlapping, in particular an overlap along the direction Y1 and the direction Z1.
- the two tongues forming the two stops B3 and B4 are secured to each other by at least one connection point between tongues, typically obtained by welding, clinching or even stapling. Such a connection point between the tongues of the stops stiffens the mechanical interface 1.
- the first support portion 2 and/or the second support portion 6 comprise several fixing tabs 7, configured to ensure the fixing of a profile forming an upright having fixing openings according to the height, by inserting the fixing tongue or tongues into one or more of the fixing openings of the profile.
- Each interface 1, 1A, 1 B, in particular right or left, can have two pairs of tabs, with a first pair of tabs 7 configured to hook two fixing openings on two height levels of a first upright M1 (or M3 ) and a second pair of tabs 7 configured to hook two fixing openings of a second M4 (or M5) upright.
- the two tongues of each pair are located respectively on the first support portion 2 and on the second support portion 6, and as visible in Figure 7B, for information purposes.
- At least one of the tongues 7, directed downwards, is configured to hook a fixing opening and can advantageously be provided with an anti-lifting device comprising an elastic tooth 8, for example example visible in Figure 4, configured to abut with an upper edge of the fixing opening, opposing the release of the fixing tongue 7.
- the elastic tooth 8 can typically be formed in one piece with the metal sheet.
- the present disclosure still relates to a storage rack comprising:
- a vertical structure comprising a set of vertical uprights M1, M2, M3, M4, typically in the form of vertical profiles,
- bracing system comprising one or more ETR bracing devices distributed over the height of the vertical structure, mechanically connecting the uprights M1, M2, M3, M4 between them
- the pair of interfaces or each pair of interfaces includes:
- the two interfaces 1A and 1B, left and right, are oriented longitudinally in the direction b.
- the support portions 4 and the connection and guide portions 3 belonging respectively to the first interface 1A and to the second interface 1 B are oriented towards each other and configured to ensure the centering of a load W inserted and deposited between the first interface 1 A and the second interface 1 B by the work of the connecting and guiding portions 3 of the two interfaces 1A, 1 B and the support of a load W supported respectively by the two support portions 4 of the two interfaces 1A, 1 B, on both sides of the load.
- the present disclosure also relates to a storage system for a warehouse comprising receptacles and at least one storage rack according to the present disclosure comprising several pairs of interfaces, distributed according to the height of the storage rack and at least one less transport system comprising one (or more) automated guided vehicle, the transport system configured to pick up and deposit said receptacle in said storage rack.
- Each receptacle is configured to be supported on both sides of the receptacle simultaneously and respectively by the support portion 4 of the first interface 1A and the support portion 4 of the second interface 1 B.
- Said automatically guided vehicle may have locomotion and tracking means in the storage system. It may in particular have two-dimensional means of locomotion on a horizontal surface, and/or three-dimensional means of movement. According to this last variant, said vehicle is then capable of moving vertically along the rack uprights.
- the vertical structure of the storage rack in particular at least one of the uprights, may comprise a rack CR1, CR2 extending along the height of the vertical structure, or a tensioned chain, extending along the height of the vertical structure.
- the automatically guided vehicle comprises a chassis, incorporating in particular a rolling mechanism on the ground, and climbing means comprising at least one toothed wheel configured to mesh with the rack CR1, CR2 or with the links of the tensioned chain of so as to allow the automated guided vehicle to climb along the vertical structure of the storage rack.
- the automatically guided vehicle comprises a deployable loading/unloading system configured to:
- the interface according to the present disclosure, or the storage rack according to the present disclosure, or the system for transporting load W according to the present disclosure finds a particular application for a load comprising one or more receptacles taken up by a pair of mechanical interfaces supporting the bin(s), up to 100 kg per supported receptacle, particularly in safety conditions.
- the load includes a receptacle in the form of a receptacle of up to 34 kg per receptacle in service conditions, and of up to 100 kg per receptacle under safety load.
- the safety load of the interfaces containing two trays with basic dimensions of 650 mm x 450 mm, and variable height, can therefore reach 200 kg in the event of filling with water following the activation of the automatic sprinkler system.
- the present disclosure is absolutely not limited to supporting light loads, but is also suitable for supporting heavier loads such as pallets, in that it also allows substantial weight savings to be made.
