B E2017 / 5534 rejjer »

The present invention relates to an assembly comprising a frame and at least one first element to be connected to said frame. Such assemblies are used in production and / or laboratory equipment, for example in the pharmaceutical field, biotechnology or microelectronics. This equipment can be for example white soil ceilings, laminar flow equipment, barrier systems restricting access, biological safety booths, isolators, hoods, chemical hoods, laminar flow hoods, weighing hood, incubator, airlock transfer.

Such assemblies are well known in the art, see for example the document GB147757Ö which discloses a clean room ceiling made up of a set of filtration units which can contain HEPÄ filters. In this case, the filtration units can be considered as elements to be connected. These units are supported on a network of rails of a support structure, and are therefore essentially maintained on the latter thanks to their own weight. The edges of the filtration units are provided with a metal skirt which is positioned so as to be received in a groove present along said rails. In addition, said skirt is immersed in a sealing fluid present inside said grooves so as to guarantee the tightness of the entire ceiling of the clean room.

This type of ceiling is generally difficult to install because at first, the installation of a support structure comprising a network of rails is necessary, Then, each filtration unit must be tilted and carried through the network of rails to finally be able to be deposited on these. In addition, the maintenance of such assemblies is not easy since each filtration unit to be maintained or repaired is quite heavy and must be lifted to be embedded in the rails, then tilted so as to be able to pass through the network of rails. . Any installation process,

B E2017 / 5534 repair or maintenance is therefore rather complex and awkward to implement and can contribute to increasing the risk of damaging said filtration units or of injuring the operator attempting to implement said process.

Another disadvantage of this type of system comes from the fact that each filtration unit is simply held by gravity on the support structure, which obliges the skilled person to limit himself to using such systems in the case of horizontal ceilings. Indeed, it appears that if such assemblies were used to embed filtration units in a vertical wall, the stability, tightness and integrity of the assembly could not be guaranteed. This type of assembly is therefore not easily applicable or adaptable to systems other than white soil ceilings and therefore lacks versatility in terms of application.

Document US4946484 deals with a support system for a clean room ceiling which can, inter alia, accommodate elements to be connected such as filters and filter panels. The latter are engaged in a support structure and are held therewith by means of a spring clip. The entire system is sealed thanks to the fact that the support structure has a skirt plunging into a groove present on the filtration panel and inside which a sealing gel is placed. As a result, the filter panels can be removed for maintenance by unhooking said spring clip. Although such systems do not require having to raise the filtration panels through the support structure, the fact remains that the presence of said spring clip adds a degree of complexity to the entire system. In addition, in terms of applications, such systems seem to be mainly limited to clean rooms and they therefore lack versatility, there is therefore a need among manufacturers and assemblers of laboratory and production equipment to make assemblies for equipment. easy to assemble, install, disassemble, maintain and

B E2017 / 5534 repair. In addition, there is a need to make versatile assemblies which are not limited to a single application.

There is also a need among equipment manufacturers to be able to make custom equipment for each of their customers. Each client having their own needs and expectations, each piece of equipment to be produced is therefore potentially different. In addition, it is important to be able to produce this equipment at a lower cost. From this point of view, there is therefore a crucial need to develop a modular assembly. “Modular” assembly is understood to mean an assembly made up of a set of building blocks also called “modules” or of elements to be connected which can be combined together and / or with other elements, in several directions in space. and / or in several orientations so as to be able, for example, to carry out laboratory and / or production equipment such as clean room ceilings, laminar flow equipment, barrier systems restricting access, biological safety cabins, isolators, hoods, chemical hoods, laminar flow hoods, weighing hood, incubator, transfer lock. The modular assemblies have the advantage of being able to be easily adapted according to the constraints of the environment in which they are installed and according to the constraints of the customer, the modular assemblies are therefore undeniably versatile,

In addition to the above characteristics, it is necessary that these assemblies are simple to assemble and require as few different parts as possible, this in order to limit the manufacturing and assembly costs.

To at least partially solve the above problems and drawbacks, there is provided according to the invention an assembly comprising a frame and at least a first element to be connected to said frame, in which at least a first and a second longitudinal section are arranged in parallel one with respect to the other, each longitudinal section comprising a first engagement means extending longitudinally, from a first face, said at least one first element to be reise comprising at least a first and a second side longitudinal parallel to each other, each parallel longitudinal side comprising mutual engagement means, complementary to said first engagement means, extending longitudinally on said each longitudinal side, said first engagement means and said mutual engagement means complementary to said first engagement means being formed of an inwardly extending groove, the said throat having at least one throat bottom and two facing walls each comprising at least one shoulder so that said throat has a first throat section SI and a second throat section $ 2, said first throat section SI being lower to said second groove section 52, arranged downstream of the first groove section, in the direction of an opening towards a bottom of the groove, said shoulder being disposed at a predetermined distance Dx measured along a plane extending along one of the walls and passing through said shoulder, from said shoulder towards said bottom of the groove, and from a projecting wall having a proximal part and a distal part, said distal part of said protruding wall being arranged to be housed in said groove and being provided with a series of protrusions arranged to rest on said shoulder of said groove, said series of protuberances was nt disposed at a predetermined distance from a distal end of said protruding wall Dy, Dy being measured between the distal end of the protrusion and one end of said series of protrusions, ia further from the distal end of the protrusion, along the projecting wall with Dx> Dy, said first element to be connected being forcibly engaged in said framework, so that each series of protrusions of the projecting walls of said first engagement means or said engagement means mutual rests on a shoulder of a groove of said mutual engagement means or said first engagement means.

As can be seen, the assembly according to the present invention allows the element to be connected to be engaged in the framework by means of a first engagement means and a mutual engagement means. This forced engagement is, among other things, possible thanks to

B E2017 / 5534 to the fact that each series of protrusions of the walls projecting from said first engagement means or from said mutual engagement means rests on a shoulder of a groove of said mutual engagement means or from said first engagement means.

It has been observed that this has the effect of being able to install and uninstall the assembly in a simple and easy manner. In addition, the maintenance of the element to be connected is made easier since the element to be connected can be easily engaged and disengaged from the frame. Indeed, the element to be connected being simply engaged in the framework, there is no need for example to carry the element to be connected through the framework and then to rest it on the latter. In addition, no other part, such as a spring clip is absolutely necessary for carrying out the assembly. The simplicity of assembly therefore allows the equipment manufacturer to make substantial savings, whether during installation of the assembly, maintenance or its manufacture,

It has also been unexpectedly and singularly discovered that despite the simplicity of the first engagement means and of the mutual engagement means and more particularly the fact that each series of protrusions of the walls projecting from said first engagement means or from said means mutual engagement rests on a shoulder of a groove of said mutual engagement means or said first engagement means, allows the first element to be connected to be securely and stably engaged in said frame. Even more unexpectedly and singularly, it has been observed that this allows the first element to be connected to remain engaged in the framework in a safe and stable manner whatever the orientation of the assembly. That is to say that the element to be connected may in particular be arranged in a vertical position or in a horizontal position so that the element to be connected is only retained in the framework by means of the series of protrusions. resting on the shoulder, without detaching from the frame despite gravity. This has the advantage that an assembly according to the invention is modular, versatile and not only limited to horizontal placements.
