Description

Technical area

This description describes the field of clean room combinations. In particular, it is a question of the field of clean room suits comprising at least one upper part adapted to cover the trunk, the hips, the pelvis and the arms of a user and a lower part adapted to cover the user's legs. and linked to the upper part.

It is also a question of a method of dressing such a clean room suit.

State of the art

A clean room is a room where the amount of particles suspended in the air is controlled so that it does not exceed a value determined according to the class of the clean room. Thus, attention is paid to the introduction, generation and retention of particles within the clean room. Other parameters are also controlled such as temperature and humidity.

A source of introduction of particles into the atmosphere of the clean room is the operator. The particles that the operator can introduce therein may be dander, hair, hair, textile particles, or any other particle that could adhere to the outer surface of the body of the operator or the clothing and shoes he door.

In order to minimize particles from this source, the operator wears a combination comprising an upper part adapted to cover the trunk, the hips, the pelvis and the arms of the user, a lower part adapted to cover his legs, and possibly a head part to cover the head.

For clean rooms of classes corresponding to a quality of drastic atmosphere, that is to say that the quantity of particles in The suspension must be extremely low, at least the upper part and the lower part are connected to each other.

The combinations of which the upper part and the lower part are connected to each other are difficult to take on account of their size. Indeed, during the dressing procedure, we must be careful not to drag any part of the combination, whatever it is, otherwise the combination can not be used to enter the clean room.

In order to remedy this, combinations allowing a covering in which the hands of the operator are released exist.

For example, the document FR2810855 describes a suitable combination for a dressing process that does not require a third person. This combination comprises an upper part adapted to cover the trunk, the hips, the pelvis and the arms of a user, a lower part adapted to cover the legs of the user and linked to the upper part, and a suitable head part to cover the head and tied to the upper part. The combination includes an openable closure at the crotch zone of the lower part. The combination can then be folded so that the lower part is turned over so that the inner face thereof is turned outwards and the front side and the rear side of the lower part are arranged on the other side. else of the upper part. Additional fasteners are provided on the lower part at the lower edge of each leg and on the upper part at the waist. Thus, the legs of the lower part can be kept folded thanks to these fasteners. The combination further comprises an attachment member on the top of the hood-shaped head portion.

The dressing method described in this document requires the use of a particular suspension device to suspend the combination by the attachment member and the lifting above the head of the user with the help of a lever. Thus, there is no risk that the suit drags on the ground during dressing. The user stands under the raised combination and activates the lever to lower the suit to its level.

A disadvantage of the combination described in FR2810855 is to require the suspension device to lift the suit high enough for it is located above the user's head, which requires a room with a very high ceiling height. Moreover, the operator must be sometimes below the combination, sometimes outside to activate the lever to lower the combination.

Presentation

An object of the present object is to overcome at least one of the disadvantages of the prior art.

In particular, one of the aims is to propose a cleanroom suit adapted to allow a dressing process freeing the two hands of the user without requiring an additional device.

For this purpose, a clean room suit is provided comprising an upper part adapted to cover the trunk, the hips, the pelvis and the arms of a user and a lower part adapted to cover the user's legs and connected to the part. high,
each part having an outer face and an inner face adapted to be turned towards the body of the user once the suit is coated,
the combination comprising a closure having an open position for passing the user's body and a closed position,
characterized in that it further comprises a strap fastened to the inner face of the upper part so that it can be passed around the neck of the user to hang the suit, the two hands of the user being thus released, the length of said strap being adapted so that when said combination is hanged on the neck of the user, said combination is then above the ground without touching, while the inner faces of the parts which fall back to the ground can be manipulated by the user to allow him to thread said combination.

The strap allows to hang the suit around the neck of the user freeing his hands. Thus, the combination is easier to handle during dressing. No device is needed, nor third party.

The optional and non-limiting features of the combination are as follows.

The closure can be located in the lower part in a crotch area. The upper part then has a body passage opening.

The strap can be attached to an area of the upper part corresponding to the thorax of the user once the suit is coated.

The strap can be fixed in two places in the upper part.

The strap can be attached to either of two shoulder areas of the suit.

The combination may further comprise a head portion adapted to at least partially cover the head of the user.

A dressing process of the combination above is also proposed.

• saisir la combinaison par la face intérieure d'une des parties ;
• passer la sangle autour du cou de manière à ce que la combinaison soit ainsi suspendue ;
• enfiler la combinaison ;
• fermer la fermeture, la disposant en position fermée.

This dressing process comprises the steps of, the closure being in the open position:

• seize the combination by the inner side of one of the parts;
• pass the strap around the neck so that the suit is thus suspended;
• put on the suit;
• close the closure, placing it in the closed position.

The optional and nonlimiting features of the process are as follows.

• le tronc, les hanches, le bassin et les bras de l'utilisateur sont passés à travers l'ouverture à l'intérieur de la partie haute ; et
• la partie basse retombe sur jambes de l'utilisateur.

When the closure is located in the lower part in a crotch zone and the upper part has a body opening, the step of donning the combination can be performed as follows:

• the trunk, hips, pelvis and user's arms are passed through the opening inside the upper part; and
• the lower part falls on the user's legs.

When the combination comprises a head portion adapted to at least partially cover the head of the user, the step of donning the suit may further include passing the user's head into the head portion.

The combination can be presented folded at least at the level of the strap, where it is fixed, so that the inner face of the upper, lower and possibly head parts, with the exception of the portions greater than where is fixed the strap and portions of the left and right arms are facing outwards, that is to say, upside down, the upper portions where the strap is attached and the left and right arm portions being place.

The adjectives "high", "low", "upper", "lower", "inner", "outer", "left", "right" and their derivatives must be understood here by compared to the combination once dressed and compared to the user who wears it, when the latter is standing.

Cleanroom suit

A clean room combination discussed here will be described below with reference to Figures 1 to 3 .

The combination is described below in relation to a user whose size corresponds to that of the combination.

This combination 1 comprises an upper part 11 and a lower part 12 connected to the upper part 11.

The term "bound" here means that the transition between the upper part 11 and the lower part 12 is performed either without assembly or with assembly. That is, a piece of fabric can be used both for a portion of the top portion and a portion of the bottom portion, or for a portion of the top portion and a portion of the bottom portion. can be assembled by any fastening means such as seam, zipper, buttons, snaps, etc.

The upper portion 11 is adapted to cover the trunk, hips, pelvis and arms of a user. For this, the upper part 11 comprises a trunk portion 111 to cover the trunk and hip, a left arm portion 112 to cover the left arm and a right arm portion 113 to cover the right arm. The portions of the left arm 112 and right 113 are generally in the form of a tube or of a truncated cone, a first end being connected to the trunk portion 111, and a second handle end or optionally attached to a handle 114, 115. The trunk portion 111 comprises an upper opening for the passage of the head and a lower opening for the passage of the trunk and arms, the upper part 11 being fixed to the lower part 12 at this opening.

The lower part 12 is adapted to cover the legs of the user. For this, the lower part 12 has a left leg portion 122 to cover the left leg and a right leg portion 123 to cover the right leg.

Each portion 11, 12 has an outer face 11a, 12a adapted to be turned towards the outside and an inner face 11b, 12b adapted to be turned towards the body of the user once the combination 1 coated.

Combination 1 further includes a closure 15 having an open position for passing the user's body and a closed position. The closure 15 is preferably located in the lower part 12 in a crotch zone 12z leg portions 122, 123 and corresponding to the crotch of the user once the combination 1 coated. In this case, it advantageously extends between the lower end 1221 of the left leg portion at the lower end 1231 of the right leg portion.

The closure 15 is advantageously a zipper ensuring a better seal than the snaps.

The combination 1 further comprises a strap 14, 24 fixed on the inner face 11b of the upper part so as to be passed around the neck of the user to hang the combination 1, thus freeing the two hands of this one. this. The length of the strap 14, 24 is adapted so that when the combination 1 is suspended from the neck of the user, it is above the ground without touching it, while the inner faces 11b, 12b of the upper parts and bass that fall to the ground can be manipulated by the user to don the combination 1.

For example, the length of the strap is chosen so that the attachment area 11z2, 11z3; 21z2, 21z3 of the inner face 11b of the upper part to which is attached the strap 14, 24 is located substantially at the portion of the body of the user to face the attachment zone 11z2, 11z3; 21z2, 21z3 once the combination 1 coated. The attachment zone 11z2, 11z3; 21z2, 21z3 is preferably an area corresponding to the thorax of the user once the combination is coated.

The strap 14, 24 can be fixed at two locations 142, 143; 242, 243 of the inner face 11b of the upper part.

The attachment zone may be located in an area 11z corresponding to the shoulders of the user once the combination 1 coated. The strap 14 can then be fixed on one side to an area 11z2 corresponding to the left shoulder of the user and on the other hand on a zone 11z3 corresponding to the right shoulder of the user.

The attachment zone may be located in a zone 21z corresponding to the underarms of the user once the combination 1 coated. The strap 14 can then be fixed on one side to an area 21z2 corresponding to the left armpit of the user and on the other hand to a zone 21z3 corresponding to the right armpit of the user.

The left arm 112 and right arm portions 113 may include fasteners 118, 119 at their handle end or connected to a handle 114, 115. In this case, the left leg 122 and right leg portions 123 also include fasteners 128, 129. complementary to the fasteners 118, 119 of the left and right arm portions. Thus, in order to prevent the portions of left 122 and right legs 123 from dragging on the ground, they can be previously attached to the left arm 112 and right 113. The fasteners 118, 119, 128, 129 are just before closing the closure 15 in the crotch zone 12z. The fasteners 118, 119, 128, 129 are preferably snaps.

The left and right leg portions may also include fasteners 124, 125 for attaching to each other. These fasteners 124, 125 are advantageously located in an upper zone of the crotch zone 12z. These fasteners are advantageously snaps.

Combination 1 may further comprise a head portion 13 adapted to at least partially cover the head of the user. This part of the head 13 may be linked to the upper part 11.

The head portion 13 includes a face portion 131 adapted to cover the user's face, from the neck to under the eyes, and a hood portion 132 covering the neck, and the hair of the user. The face portion 131 and the hood portion 132 give the head portion 13 a hood shape.

The head portion 13 may also comprise fasteners 134, 135, one on the left and one on the right, for example straps, for fixing protective spectacles, for example goggles conforming to those described in document FR2928260 .

The combination 1 may further include a marking allowing the user to easily position the folded combination in the correct direction to perform the dressing process described below.

Dressing process

A dressing process of combination 1 above will be described below with reference to Figures 4a to 4j .

• saisir la combinaison par la face intérieure d'une des parties ;
• passer la sangle autour du cou de manière à ce que la combinaison 1 soit ainsi suspendue (figure 4a) ;
• enfiler la combinaison 1 (figures 4b à 4h) ; et
• fermer la fermeture 15 (figure 4i), la disposant en position fermée.

This method comprises the steps, the closure 15 in the open position:

• seize the combination by the inner side of one of the parts;
• pass the strap around the neck so that the combination 1 is thus suspended ( figure 4a );
• put on the combination 1 ( Figures 4b to 4h ); and
• close the closure 15 ( figure 4i ), disposing it in closed position.

• les bras, la tête, le tronc, le bassin et les hanches de l'utilisateur sont passés à travers la partie haute 11, de préférence dans cet ordre (figures 4b, 4c, 4d) ;
• si la combinaison 1 comprend une partie de tête 13, la tête y est passée à l'intérieur et la partie de tête 13 est fixée à la tête de l'utilisateur au moyens des fixations 134, 135 prévus (figure 4e) ;
• éventuellement, les fixations 124, 125 reliant les deux portions de jambes gauche 122 et droite 123 sont détachées (figure 4f) ;
• éventuellement, les fixations 118, 119, 128, 129 reliant les portions de jambes gauche 122 et droit 123 aux portions de bras gauche 112 et droit 113 respectivement sont détachées (figures 4g, 4h) ;
• les portions de jambes gauche 122 et droite 123 retombent de part et d'autre des jambes de l'utilisateur quand celui-ci se met en position droite ou une fois les fixations 118, 119, 218, 219 fixant les portions de jambes 122, 123 aux portions de bras 112, 113 détachées (figure 4g, 4h).

The step of threading combination 1 can be performed as follows:

• the arms, head, trunk, pelvis and hips of the user are passed through the upper part 11, preferably in this order ( Figures 4b, 4c, 4d );
• if the combination 1 comprises a head portion 13, the head is passed inside and the head portion 13 is fixed to the head of the user by means of the fasteners 134, 135 provided ( figure 4e );
• possibly, the fasteners 124, 125 connecting the two portions of left leg 122 and right 123 are detached ( figure 4f );
• possibly, the fasteners 118, 119, 128, 129 connecting the left leg portions 122 and right 123 to the right arm 112 and right arm portions 113 respectively are detached ( figures 4g, 4h );
• the portions of left leg 122 and right 123 fall on both sides of the user's legs when it is placed in the upright position or once the fasteners 118, 119, 218, 219 fixing the leg portions 122, 123 to the detached arm portions 112, 113 ( figure 4g, 4h ).

This dressing method is particularly advantageous when the combination 1 is presented folded at least at the fastening zone 11z, 21z of the strap 14, 24 so that the inner face of the entire combination, to with the exception of the portions greater than the attachment zone 11z, 21z and left arm 112 and right arm portions 113, being turned outward (and therefore upside down), the portions greater than the fixing zone 11z, 21z and left arm portions 112 and right 113 being in place. Other folds may also be made in order to reduce the size of the folded combination, for example, folds substantially perpendicular to the length of the combination, a portion of the inner face of the upper part being shown to turn towards the outside so that the user can enter the combination by this face. The user will only have to shake the combination to unfold and to have access to the strap 14, 24 to pass around his neck. When the attachment zone 11z, 21z is located at the shoulders or armpits, once the strap passed around the neck of the user, the combination hangs and only the inside of the portions other than the portions above the Fixation area and left and right arm portions can be easily touched by the user. The outer face of the entire suit is protected. Furthermore, the openings connecting the arm portions 112, 113 to the trunk portion 111 are easily accessible for dressing ( Figures 3a and 3b ). To pass the arms inside the upper part 11, the user has only to move his arms directly into the left and right arm portions and his hands out by the handle end ( Figure 4b and 4c ). Then the head has passed through the upper opening by grasping the inner face 11b of the upper part near the upper opening, for example the portion of the combination lying near the chin of the user ( figure 4d ). The passage of the trunk, pelvis and hips then follows naturally when the leg portions left 122 and right 123 fall.

This method allows a user to wear the cleanroom suit alone and without touching the outer face 11a, 12a of the different parts.

Undressing process

The combination 1 described above also allows an easy undressing method to touch as little as possible the outer face 11a, 12a of the different parts and without loss of orientation.

For this, the user completely opens the closure 15 located at the level of the crotch zone 12z, then leans the top of his body forward then grasps the combination 1 at the level of his back to pull it forwards . This gesture allows both the user to return the entire combination with the exception of the portions greater than the attachment area and the left arm portions 112 and right 113.

Thus, at the end of undressing, the combination 1 can be suspended from a carrier, for example by means of the strap 14, 24, while being advantageously folded to carry out again the dressing process described above in the where the user wishes to reuse the combination 1.
