Description

The invention relates to a watertight door intended to equip a clean room or the like and comprising a frame and an opening frame, on the one hand, pivotally mounted or sliding on the frame and on the other hand, adapted to close on the latter in a sealed manner, said opening being defined by an internal frame on which are reported, on the one hand, an inner facing and, on the other hand, an outer facing, at each of these facings being made, in correspondence, a cutout, these cuts defining an opening inside which is mounted a transparent panel.

The present invention relates to the field of the manufacture of doors able to close airtight clean rooms such as clean rooms or operating rooms in which prevails a sterile atmosphere, an overpressure or depression by relative to the atmospheric pressure.

We already know many doors as described above. Such doors allow authorized personnel to enter or leave a clean room by opening the door.

In this regard, it will be observed that such an opening, on the one hand, disrupts the sterile nature and / or the maintenance under pressure of said clean room and, on the other hand, facilitates the penetration of micro-organisms and dust.

It is, therefore, essential to reduce, in a particularly draconian manner, to the strict minimum the number of openings / closings of such a door.

It will be noted that such a door is usually completed by a sliding window located at the wall of the clean room, this completely independent of said door. Such a window is designed so as to allow the passage of tools, including sterile surgical instruments, essential to the accomplishment of the tasks incumbent on the staff confined in said clean room.

The existence of this wicket therefore authorizes the supply of equipment personnel without such a supply necessitating the opening of the watertight door. It should, however, <B> be observed that <B> the presence of such </ B> <B> wicket </ B> imposes <B> no </ B> only, <B > when carrying out such a clean room, to provide, at the level of the wall, a <B> location <B> for </ B> <B> the implantation of this wicket <B> but <B> also the realization of this <B> <B> last, while respecting the inherent sealing constraints </ B> <B> to the <B> operation <B> of a such a clean room. </ B>

The <B> present invention is to <B> even <B> to remedy these </ B> <B> disadvantages through a door of new design and <B> <B> particularly clever. </ B> / B>

<B> To this end, the present invention relates to a watertight door </ B> <B> intended to </ B> equip <B> a clean room or <B> and </ B> including < B> a </ B> <B> frame </ B> as well <B> as </ B> as an opening, <B> on the one hand, pivotally mounted <B> or sliding on this frame </ B> dormant <B> and, on the other hand, able to <B> close <B> on the latter <B> way <B> waterproof, said opening being </ B> <B> defined by an internal framework on which is <B> <B>, <B> <B> internal <B> and, on the other hand, an external facing, </ B> > <B> level of each of these facings being realized, in correspondence, </ B> <B> a cutout, these cuts defining an opening inside </ B> <B> which is mounted a </ B > transparent <B> panel, characterized by the fact that </ B>. - <B> said internal framework delimits, between the internal and external </ B> <B> siding, <B> an internal volume <B> able to receive, on the one hand, two </ B> <B> vertical guide slides and, on the other hand, said transparent board having slidable lateral ends in these guide slides said opening is bordered, on the one hand, by <B> lateral <B> way by <B> said <B> vertical guidance </ B> and, on the other hand, </ B> by <B> an upper border and <B> a lower border </ B>; - <B> said lateral slides as well as the borders </ B> upper <B> and lower are </ B> completed <B> by means able to ensure a </ B> <B> waterproof contact with said </ B> transparent panel.

<B> According to </ B> another <B> other </ B> feature, <B> these side slides </ B> <B> adopt a <B> U-shape </ B> defining </ B> B> a groove within </ B> which slides said panel, <B> said groove being delimited by </ B> <B> two parallel wings <B>, <B> > connected by a bottom, and of which </ B> one <B> to <B> less is provided, on its internal face oriented in the direction of </ B> the other wing, of suitable means to ensure a sealed contact with said sliding panel.

An additional feature relates to the fact that the sealing contact means are defined by a vee joint made integral, in particular by gluing, as the case may be, the inner face of said wing of the slide and / or the upper edge, at the the inner face of the latter oriented towards said transparent panel.

According to another characteristic, the lower edge of the opening is defined by a support plane adapted to cooperate, in the closed position of said transparent panel, with a running seal, on the one hand, equipping the lower end of said transparent panel and, secondly, defining said means adapted to ensure a sealed contact.

An additional feature is that said door is completed by means capable of compensating for the weight of said transparent panel.

According to a first characteristic, said means capable of compensating for the weight of the panel are defined by a spring, in particular of helical type, and connected at one of its ends to a fixed point of the door while its other end is associated to a shaft, on the one hand, rotated in the upper part of said door and, on the other hand, connected to said panel via at least one connecting cable adapted to wind around said shaft.

According to another characteristic, the means capable of compensating for the weight of said panel are defined by at least one counterweight connected to said panel by means of a cable adapted to wind, at least partially, around a return pulley arranged in the upper part of the door.

In this regard, it will be observed that the guide slides adopt a U-shaped shape defining a groove within which said panel slides, said groove being delimited by two parallel wings, connected by a bottom, at least one of these guide slides being completed by two additional parallel wings extending from the bottom of the slide in a direction opposite to that of the wings of the sliding groove of the panel, these additional wings defining an additional groove within the which is able to slide the counterweight.

 Finally, said door is completed by means of motorized type able to control in motion said sliding panel, such means being arranged in the internal volume delimited by <B> the internal frame and the </ B> facings.

The advantages of the present invention consist in that the transparent panel equipping, usually, a sealed door is sliding in nature with respect to an opening made at this door. This sliding panel is, advantageously, able to define a window, for example, for the supply of the clean room equipment.

With the present invention, it is no longer necessary to provide or define, at the wall of a clean room, a location for receiving a window for the passage of equipment. The present invention also makes it possible to avoid the manufacture of such a window as well as its installation at the wall of said clean room.

It will be observed that the sliding panel is advantageously completed by seals associated with the guide slides, at least one of the borders and / or said panel itself, these seals being able to guarantee the seal at level of said sliding panel, more particularly in the closed position of the latter.

By using a sealed door defined from a frame covered with facings, it is advantageously possible to ensure the sliding assembly of said panel in the same thickness of said door. Such an embodiment allows to embed the panel in said door which significantly reduces the number of recesses and raised parts at which would be likely to accumulate dust or other undesirable elements and difficult to eliminate.

Other objects and advantages of the present invention will become apparent from the following description relating to an embodiment which is given by way of indicative and non-limiting example.

The understanding of this description will be facilitated with reference to the accompanying drawings in which - Figures 1 and 3 are schematic and perspective views corresponding to a sealed door according to the invention and comprising a sliding panel, respectively in the closed position and open; - Figures 2 and 4 are schematic, partial and sectional views along AA and BB corresponding to the doors shown in Figures 1 and 3; - Figure 5 is a schematic perspective view of a door according to the invention defined from an internal frame, usually covered with an outer facing and an inner facing, and where only the outer facing, defining for example, the back of this door is shown, this door having a sliding panel shown in the intermediate position; - Figure 6 is a schematic and partial view corresponding to a section along CC made at the door shown in Figure 5, here covered with an outer and inner facing.

The present invention relates to the field of the manufacture of watertight doors intended to equip a clean room, including a clean room, an operating room or other.

Such a door 1 is defined, usually, by a frame on which is mounted, slidably or pivotally, an opening 2.

The latter 2 and / or said fixed frame are equipped with a peripheral seal 3 able to allow sealing, sealing said opening 2 of said frame.

In fact, such an opening 2 is defined, in the present case, by an internal framework 4 on which are reported, on the one hand, an inner facing 5 and, on the other hand, an outer facing 6.

In this regard, it will be observed that the qualifiers of internal and external attributed to these facings 5 and 6 result from the orientation of the latter with respect to the clean room equipped with such a door 1. Thus, the facings internal 5 and outer 6 correspond to the side of the door 1 oriented, respectively, inwardly and outwardly of this room.

As can be seen in the appended figures, each facing 5 and 6 of this door 1 comprises a cutout 7, 8, these cuts being made in such a way that the cutout 7 of the internal facing 5 is in correspondence with the cutout 8 of the facing external 6.

It will be observed that these cutouts 7, 8 define, at the level of said door 1, an opening 9 inside which is mounted a transparent panel 10. The latter allows an observer, located outside the clean room, to see inside this and vice versa.

According to a first characteristic of the present invention and as visible, more particularly, FIG. 5, the internal framework <B> 4 </ B> of said door 1 delimits, between the internal and external facings 5 and 6, an internal volume 11. This internal volume 11 is able to receive two vertical guide slides 12, 13 as well as said transparent panel 10. The latter has, in fact, lateral ends 14, 15 able to slide, precisely, in these guide slides 12, 13, said panel 10 being, for its part, able to slide with respect to said opening 9 which the door 1 presents. In this respect, it will be observed that such sliding allows said transparent panel 10 to define a suitable aperture, for example , to authorize the supply of the equipment clean room without such a supply necessitating the opening of the door 1.

As can be seen in FIG. 5, said guide slides 12, 13 are disposed inside said internal volume 11 so as to border, laterally and on either side, the opening 9 that comprises said door 1.

This opening 9 is, furthermore, bordered, on the one hand, in its upper part, by an upper edge 16 and, on the other hand, in its lower part, by a lower edge 17. <B> According to another < / B> characteristic <B> of the present invention, these </ B> borders 16, 171 as well as the guide slides 12, 13 are completed by means 18 able to ensure a sealed contact with said transparent panel 10.

As can be seen more particularly in FIG. 6, said guide slides 12, 13 adopt a U-shaped shape defining a groove 19 delimited by two parallel wings 20, 21 connected by a bottom 22.

It is, more particularly, inside this groove 19 that the lateral ends 14, 15 of said transparent panel 10 slide.

With regard to said flanges 20, 21 delimiting said groove 19, it should be observed that it is, more particularly, at least one of them 20, 21 which is provided, on its internal face 23 oriented in the direction of the other wing 21, said means 18 able to ensure a sealed contact with said panel 10.

 However, and according to a preferred embodiment shown in FIG. 6, each of these two wings 20, 21 is advantageously provided with such sealing means 18, at their internal faces 23 facing each other. .

 As for the upper edge 16, it can, as shown in Figures 2 and 4, be defined by the end edge 24 of the facing 5, 6 defining said cutout 7, 8 at its upper end. It is, more particularly, the internal face 25 of at least one of the facings 5, 6, oriented toward the other facing 6 and said panel 10, which is capable of receiving said means 18 capable of providing a sealed contact with said panel 10.

In fact, according to a preferred embodiment shown in FIGS. 2 and 4, it is, more particularly, the internal faces 25 of each of these two facings 5, 6 which are advantageously equipped with such means. <B> 18. </ B>

In this regard, it will be observed that these sealing means 18 are designed and / or located so that the difference in air pressure between the inside and the outside of a clean room increases the efficiency of these means. 18 through better contact with said sliding panel 10 and allows, therefore, increased sealing at the latter. <B> According to a preferred embodiment, such </ B> means <B> 18 capable of </ B> <B> ensuring tight contact with said <B> panel 10 are defined by a <B> / B> <B> joint in </ B> Vé <B> 26 made integral, <B> particularly <B> by gluing, of the face </ B> <B> internal 23 of the 20 or wings 20 , 21 of the guide slide </ B> <B> 12, 13. </ B>

<B> Such </ B> <B> 18 </ B> forms <B> of a </ B> Vé <B> 26 joint can, </ B> <B> still be rendered secured, <B> in particular <B> by gluing, the upper edge 16, at the inner face 25 of the latter, oriented in </ B> direction <B> of the said <B> transparent <10> panel. </ B>

<B> According to an embodiment not shown, the lower border 17 may, like the upper border 16, be <B> <B> defined by an edge </ B> <B> end of siding <B> 5, 6 bordering the cutout <B> 7, 8. <B> again, the </ B> means <B> > 18 able to ensure a tight contact </ B> <B> can adopt the form </ B> of a <B> joint in </ B> Vé equipping <B> the internal face </ B> <B> at least one </ B> facings <B> 5, 6. </ B>

<B> However, and according to a <B> preferred embodiment <B> embodiment shown in FIGS. 1, 3 and 5, the bottom border <B> 17 of the aperture 9 is <B> <B> defined by a support plane 27. The latter can, </ B> advantageously, <B> adopt the <B> form <B> of a tablet 28 or the like, by </ B> B> example likely <B> to pass on both sides <B> <B> internal 5 </ B> <B> and external 6, on the inner and outer side of the door 1. Such < / B> <B> tablet 27 </ B> allows, advantageously, <B> to define a support </ B> for the <B> reception </ B> temporary <B> of <B> <B> material <B> intended, </ B> in particular, <B> to <B> supply the clean room. </ B>

<B> This support plane 27 is designed capable of cooperating, in the closed position of said <B> transparent panel <B> 10, with a seal </ B> <B> running 29 </ B> equipping the lower <B> end 30 of said <B> transparent panel 10, more </ B> particularly <B> the end edge of this </ B> <B> last. </ B>

<B> Such a seal 29 defines, in fact, said <B> 18 </ B> <B> means able to ensure a sealed contact with said transparent panel </ B> <B> 10 </ B> <B> It will be observed that <B> a support plan 27 defined, </ B> in particular, <B> under the <B> form <B> of a tablet 28 or the like preferably has a <B> flat surface, <B> 1, on the one hand, to avoid an accumulation of </ B> dust or other undesirable elements and, on the other hand, to allow easy maintenance and cleaning.

According to another characteristic of the present invention, said sealed door 1 is completed by means 31 able to compensate for the weight of said transparent panel 10.

According to a first embodiment not shown, such means 31 may be defined by a spring, in particular of helical type. Such a spring is connected, on the one hand and at one of its ends, to a fixed point of the door 1 and, on the other hand, at its other end, to a shaft mounted to rotate in rotation. upper part of said door 1, in particular inside the internal volume 11, for example at the upper end thereof. In fact, this shaft is connected to said transparent panel 10 by means of at least one connecting cable or the like adapted to wind around said shaft, in particular under the impulse of said spring and during the setting in motion of said panel transparent 10.

However, according to a preferred embodiment shown in FIGS. 5 and 6, the means 31 able to compensate for the weight of said panel 10 take the form of at least one counterweight 32 connected to said panel 10 by means of a cable 33 adapted to at least partially around a deflection pulley 34 arranged in the upper part of the door 1. Such a counterweight 32 is disposed in the internal volume inside which it is likely to adopt a vertical movement. of ascending or descending type.

As evoked above, the guide slides 12, 13 adopt a U-shaped shape defining a groove 19, within which said panel 10 slides, and delimited by two parallel wings 20, 21 connected by a bottom 22. .

At least one of these guide slides 12, 13 is completed by two additional parallel wings 35, 36 extending from the bottom 22 of the slide 12, 13, in a direction opposite to that of the wings 20, 21 of the sliding groove 19 of the panel 10. In fact, these additional wings 35, 36 define an additional groove 37 inside which is slidably mounted said counterweight 32.

 As can be seen in FIG. 6, the presence of these additional wings 35, 36 makes it possible to give said guide slide 12, 13 an H-shape.

As can be seen in FIGS. 1, 3 and 5, the transparent and sliding panel 10 is completed, preferably on either side, by at least one handle 38 able to allow manual movement of said panel 10 by an operator.

However, according to an embodiment not shown, this watertight door 1 can be completed by means of motorized type able to control the movement of said panel 10. Such control means are preferably located in the upper part of the door 1 and may advantageously be arranged in the internal volume 11 delimited by the internal framework 4 and the facings 5, 6.

In fact, such motorized means adopt, for example, the form of an electromechanical system consisting of a tubular geared motor which drives a drum on which a suspension cable connected to said panel 10 is wound.

It will be observed that these control means can be controlled via at least one control button adopting, for example, the shape of a switch.

The latter can be arranged specifically to allow actuation other than by the hands, this, in particular, for sterility issues.

Although the invention has been described with respect to a particular embodiment, it is understood that it is in no way limited and that various modifications of shapes, materials and combinations thereof can be made. various elements without departing from the scope and spirit of the invention.
