Abstract

The present invention relates to an anchoring device for the covering (9) of a fabric boom on its associated support, which provides for extraction of the totality of the piece of fabric (9), including its extremities.This extraction, accomplished by means of a roller extractor, is made possible by providing anchor studs (14) having an underlying recess and extending from the upper surface of the support (1-3), through the use of articulated lever-shaped connecting grips (5) on support (1-3) having an arm that exerts pressure on appendages (15) of the piece of fabric (9) without interfering with the heads of anchor studs (14), and lateral shoulders (13) on support (1-3) configured in such a way that they define between them a determinate space from which neither anchor studs (14) nor connecting grips (5) emerge.

Description

La présente invention concerne un dispositif d'ancrage du revêtement d'un balai de tissu sur son support associé.The present invention relates to a device for anchoring the coating of a cloth broom on its associated support.

Ainsi qu'il est bien connu on emploie, pour le nettoyage des sols, les "balais de coton" qui se composent d'une partie active, constituée d'une pièce de tissu maintenue étendue et fixée en position de travail par un support associé en forme de planchette.As is well known, for the cleaning of the floors, the "cotton brooms" are used which consist of an active part, consisting of a piece of fabric kept extended and fixed in the working position by an associated support in the form of a board.

Ce support, réalisé d'une manière générale en matière plastique résineuse, est composé de plusieurs pièces articulées entre elles et rendues coplanaires pendant les opérations normales de nettoyage. Dans la zone centrale du support se trouve une attache pour le manche du balai.This support, generally made of resinous plastic material, is composed of several parts hinged together and made coplanar during normal cleaning operations. In the central area of the support is a tie for the handle of the broom.

La pièce de tissu est maintenue par le support au moyen de l'accrochage d'appendices prévus aux extrémités de la pièce de tissu et ce au moyen de deux pinces formant leviers articulées dans des sièges formés dans des saillies qui se dressent latéralement dans les parties extrêmes de la surface supérieure du support.The piece of fabric is held by the support by means of the attachment of appendices provided at the ends of the piece of fabric and by means of two lever clamps hinged in seats formed in protrusions which rise laterally in the parts extremes of the upper surface of the support.

Pour une bonne utilisation des balais précités, il est nécessaire d'avoir une bonne tension de la pièce de tissu et un accrochage sûr de la pièce de tissu qui ne cède pas sous l'effet de sollicitations particulières, telles que, par exemple, par suite de l'insertion de la pièce de tissu dans des fissures ou de la présence d'aspérité sur les sols à traiter, et il est également nécessaire qu'il soit possible d'effectuer un essorage de la totalité de la pièce de tissu y compris ses parties extrêmes.For a good use of the aforementioned brushes, it is necessary to have a good tension of the piece of fabric and a secure fastening of the piece of fabric that does not give in under the effect of particular stresses, such as, for example, by following the insertion of the piece of fabric in cracks or the presence of roughness on the floors to be treated, and it is also necessary that it is possible to spin the entire piece of fabric including its extreme parts.

En ce qui concerne la tension et l'accrochage de la pièce de tissu, les moyens adoptés jusqu'à ce jour dans les différents types de balais peuvent être considérés comme étant efficaces. Par contre, pour ce qui est de l'essorage, on a pas obtenu jusqu'à présent une efficacité totale.Regarding the tension and the attachment of the piece of fabric, the means adopted to date in the different types of brushes can be considered effective. On the other hand, as far as spinning is concerned, up to now no total efficiency has been obtained.

En fait, lorsque l'on doit effectuer l'essorage de la pièce de tissu, le support, soutenu au centre par le manche, est désarticulé pour cesser d'être plan, ce qui a pour effet que les parties extrêmes du support prennent une position inclinée vers le bas et que la pièce de tissu, maintenue accrochée, par l'intermédiaire de ses appendices, par les pinces du support, prend la configuration d'un feston pendant. Les extrémités de la pièce de tissu ne se trouvent plus alors totalement en dessous du support mais elles sont adossées partiellement au support lui-même.In fact, when you have to wring the piece of fabric, the support, supported in the center by the handle, is disarticulated to stop being flat, which has to This is because the end portions of the support assume a downwardly inclined position and the piece of fabric, held in place by its appendages by the support clamps, assumes the configuration of a hanging festoon. The ends of the piece of fabric are then no longer completely below the support but they are partially backed to the support itself.

On insère, avant des opérations d'immersion pour le lavage et pour le rinçage, la pièce de tissu dans un appareil d'essorage.Prior to immersion operations for washing and rinsing, the piece of cloth is inserted into a wringer.

Il est évident que la compression obtenue avec les différents types d'appareils d'essorage concerne la partie de la pièce de tissu qui se trouve en dessous des composants solides du support. Les parties de la pièce de tissu qui sont adossées au support restent naturellement à essorer. Ceci signifie que la pièce de tissu n'est pas totalement nettoyée et qu'elle continue à avoir des parties non essorées et imprégnées de liquide sale. Le nettoyage des sols dans leur ensemble se ressent de cette situation. L'emploi d'un appareil d'essorage à rouleaux opposés ne réussit pas également à obtenir l'essorage total d'une pièce de tissu parce que, étant donné la structure des supports actuels, les rouleaux ne sont pas en mesure de tourner en comprenant entre eux les parties solides du support et ne sont pas de ce fait en mesure d'essorer les parties extrêmes de la pièce de tissu adossées au support.It is obvious that the compression obtained with the different types of spinning apparatus concerns the part of the piece of fabric which is below the solid components of the support. The parts of the piece of fabric that are leaning against the support naturally remain to be wrung. This means that the piece of fabric is not completely cleaned and that it continues to have unsprayed parts and impregnated with dirty liquid. Soil cleaning as a whole is affected by this situation. The use of an opposing roller wringing apparatus also fails to obtain a total wringing of a piece of cloth because, given the structure of the present supports, the rolls are not able to turn into comprising between them the solid parts of the support and are therefore not able to wring the end portions of the piece of fabric backed to the support.

La présente invention permet de résoudre le problème précité et, tout en conservant la validité d'une tension active de la pièce de tissu et d'un accrochage sûr des appendices dont est pourvue la pièce de tissu, elle permet d'obtenir l'essorage total de la pièce de tissu y compris ses parties extrêmes.The present invention solves the aforementioned problem and, while maintaining the validity of an active tension of the piece of fabric and a secure attachment of appendices which is provided with the piece of fabric, it allows to obtain the spin total of the piece of fabric including its extreme parts.

Pour obtenir l'essorage de la totalité de la pièce de tissu, y compris ses parties extrêmes, les innovations qui sont apportées, par rapport à ce qui existe déjà, sont exposées ci-après.In order to wring out the entire piece of fabric, including its end parts, the innovations that are made, compared to what already exists, are described below.

Premièrement : Sur la surface supérieure du support, dans les zones de ses parties extrêmes, se dressent des plots qui sont configurés avec une entaille sous-jacente. Ces plots présentent, sur un tronçon de leur partie inférieure s'étendant à partir de leur zone d'attache, des décrochements réalisant des entailles appropriées. Les bords de trous (renforcés ou non par des oeillets) formés dans les appendices de la pièce de tissu s'insèrent dans les entailles et par conséquent, lorsque la pièce de tissu est tendue, ces trous empêchent que les appendices ne se soulèvent et ne se dégagent des plots. First : On the upper surface of the support, in the zones of its extreme parts, there are studs which are configured with an underlying cut. These studs have, on a portion of their lower part extending from their attachment zone, recesses making appropriate notches. The edges of holes (reinforced or not by eyelets) formed in the appendages of the piece of fabric are inserted into the notches and therefore, when the piece of fabric is stretched, these holes prevent the appendages from rising and emerging from the studs.

Deuxièmement : Les pinces d'accrochage ont, suivant l'invention, une forme de levier avec des bras sensiblement égaux. Les tétons ou tourillons de ces pinces formant leviers sont articulés sur des épaulements latéraux qui se dressent dans les zones des parties extrêmes du support. Le bras de levier qui s'étend vers l'intérieur du support, est repoussé vers le haut par un ressort sous-jacent tandis que le bras de levier opposé, qui s'étend vers l'extérieur, est par conséquent repoussé vers le bas en comprimant, contre le support, les appendices de la pièce de tissu qui sont accouplés avec les plots d'accrochage, en empêchant ainsi que les appendices ne se soulèvent. Pour que ce bras puisse assumer sa fonction, il est pourvu de trous de manière à ne pas interférer avec les plots sous-jacents du support. Second : The gripping clamps have, according to the invention, a lever shape with substantially equal arms. The nipples or pins of these levers levers are articulated on lateral shoulders that stand in the zones of the end portions of the support. The lever arm extending inwardly from the support is pushed upwards by an underlying spring while the opposite lever arm, which extends outwards, is therefore pushed downwards. compressing, against the support, the appendages of the piece of fabric that are coupled with the attachment studs, thereby preventing the appendages from rising. For this arm to assume its function, it is provided with holes so as not to interfere with the underlying studs of the support.

Troisièmement : Les épaulements latéraux qui sont prévus dans les parties extrêmes du support sont conformés de manière à définir entre eux un espace dans lequel sont maintenus aussi bien les plots d'accrochage solidaires du support que les pinces d'accrochage formant leviers, même lorsque ces pinces se trouvent comprimer les appendices de la pièce de tissu insérés sous les pinces. Thirdly : The lateral shoulders which are provided in the end portions of the support are shaped in such a way as to define between them a space in which are held both the fastening studs integral with the support and the gripping tongs forming levers, even when these clamps are compressing the appendages of the piece of cloth inserted under the clamps.

Avec les trois innovations précitées, c'est-à-dire avec les plots à entaille sous-jacente qui se dressent à partir de la surface supérieure du support, avec les pinces formant leviers articulées sur le support avec un bras qui exerce une pression sur les appendices de la pièce de tissu, sans interférer avec les têtes des plots, et avec les épaulements latéraux du support qui sont conformés d'une manière appropriée afin de définir un espace déterminé entre eux, espace duquel n'émerge ni les plots à entaille sous-jacente ni les pinces d'accrochage, on obtient ce qui est exposé ci-après.With the three aforementioned innovations, that is to say with the underlying notch studs that rise from the upper surface of the support, with the lever clamps articulated on the support with an arm that exerts pressure on the appendages of the piece of fabric, without interfering with the heads of the studs, and with the lateral shoulders of the support which are shaped in a suitable manner to define a determined space between them, space from which neither the notch studs emerge underlying or the gripping pliers, we obtain what is explained below.

Lorsqu'on se trouve en phase de nettoyage, la pièce de tissu est tendue d'une manière appropriée et accrochée efficacement, ses appendices étant engagés, par leurs trous associés, dans les entailles des plots d'accrochage. Lorsque les parties externes du support se trouvent inclinées en position angulaire, les appendices sont empêchés de se dégager des plots d'accrochage parce qu'ils sont pressés contre le support par le bras de levier de chacune des pinces d'accrochage. Lorsque l'on se trouve en phase d'essorage, la présence des épaulements latéraux du support, profilés d'une manière décroissante en direction de l'extrémité, permettent l'essorage des parties extrêmes de la pièce de tissu, lorsqu'on utilise un appareil d'essorage à rouleaux opposés. Ces rouleaux, roulant en fait librement sur les épaulements latéraux du support, rencontrent les parties terminales de la pièce de tissu qui se trouvent être adossées par-dessus les extrémités des bras de levier exerçant la pression et qui sont ainsi soumises à l'essorage.When in the cleaning phase, the piece of fabric is properly tensioned and hung effectively, its appendages being engaged by their associated holes in the notches of the attachment studs. When the outer parts of the support are inclined in angular position, the appendages are prevented from disengaging the attachment studs because they are pressed against the support by the lever arm of each of the attachment clamps. When one is in spinning phase, the presence of the lateral shoulder of the support, profiled in a decreasing manner in the direction of the end, allow the spinning of the end portions of the piece of cloth, when using a spinning apparatus with opposed rollers. These rollers, actually rolling freely on the lateral shoulders of the support, meet the end portions of the piece of fabric which are abutted over the ends of the lever arms exerting the pressure and which are thus subjected to spinning.

Il convient de remarquer que la pièce de tissu est réalisée, aussi bien en largeur qu'en longueur, avec des dimensions supérieures à celles du support parce qu'au cours du nettoyage, elle peut rencontrer doucement les parois et les contours des meubles.It should be noted that the piece of fabric is made both in width and length, with dimensions greater than those of the support because during cleaning, it can meet gently the walls and contours of the furniture.

Dans les balais à pièce de tissu existant sur le marché, les portions de la pièce de tissu qui s'étendent, dans le sens longitudinal, au-dessus de son support, ne sont pas susceptibles d'être essorées et une bonne partie de la saleté recueillie pendant une phase précédente de nettoyage continue à être transportée pendant les phases de nettoyage successives, ce qui altère la quantité et la qualité du nettoyage lui-même.In the fabric brooms existing on the market, the portions of the piece of fabric that extend longitudinally over its support are not susceptible to being wrung out and a good part of the Dirt collected during a previous cleaning phase continues to be transported during the successive cleaning phases, which alters the quantity and quality of the cleaning itself.

Une autre particularité innovante relative aux balais de tissu existant sur le marché est inhérente au dispositif articulé dans l'un des éléments du support, qui, lorsqu'il est pressé, se décroche du petit nez appartenant à l'élément contigu opposé du support. Le décrochage entraîne la suppression de la planéité des éléments articulés entre eux et qui constituent le support. Ce dispositif articulé est réalisé en une seule pièce venant de moulage qui comprend aussi bien la lèvre qui vient coiffer le petit nez de l'élément contigu opposé, ce qui existe lorsque l'on désire maintenir la planéité des éléments articulés entre eux et constituant le support, que les propres tétons ou tourillons d'articulation et les branches élastiques qui fonctionnent en tant que ressorts déterminant la charge une fois en fonction. Ceci entraîne un avantage économique notable du fait de la réduction des coûts aussi bien parce que l'ensemble se réduit au moulage d'une seule pièce que parce qu'on économise le temps de main d'oeuvre nécessaire pour assembler des composants séparés.Another innovative feature relating to existing fabric brushes on the market is inherent in the device articulated in one of the elements of the support, which, when pressed, is detached from the small nose belonging to the opposite contiguous element of the support. The stall causes the removal of the flatness of the elements articulated between them and which constitute the support. This articulated device is made in one piece from molding which includes both the lip which caps the small nose of the opposite contiguous element, which exists when it is desired to maintain the flatness of the elements articulated together and constituting the support, that the own pins or hinge pins and the elastic branches that function as springs determining the load once in function. This results in a significant economic benefit due to reduced costs both because the assembly is reduced to one-piece molding than because labor time required to assemble separate components is saved.

On décrira ci-après, à titre d'exemple non limitatif, une forme d'exécution de la présente invention, en référence aux dessins annexés.An embodiment of the present invention will be described hereinafter by way of nonlimiting example, with reference to the accompanying drawings.

On peut voir sur cette figure que le support est constitué de plusieurs éléments 1,2,3 reliés les uns aux autres et pourvus, à leurs extrémités, de pinces d'accrochage 5 formant leviers, à bras sensiblement égaux.Figure 1 is a plan view of the support of a cloth broom. It can be seen in this figure that the support consists of several elements 1,2,3 connected to each other and provided at their ends with hooking clamps 5 forming levers with substantially equal arms.

La figure 2 est une vue de côté du support du balai en tissu dont les éléments le constituant 1,2 sont coplanaires entre eux. On notera que le porte-manche 6 est relié par une articulation 7 au support 1,2 et que le bouton 8 qui maintient le petit nez de l'élément central opposé émerge du profil des deux épaulements latéraux 13 du support.Figure 2 is a side view of the support of the fabric broom whose constituent elements 1,2 are coplanar with each other. Note that the handle holder 6 is connected by a hinge 7 to the support 1, 2 and that the button 8 which holds the small nose of the opposite central element emerges from the profile of the two lateral shoulders 13 of the support.

La figure 3 est une vue de côté correspondant à celle de la figure 2, le support 1,2 maintenant une pièce de tissu 9. On notera que sur cette figure les pinces d'accrochage ne font pas saillie au-dessus du profil des épaulements latéraux 13 du support.Figure 3 is a side view corresponding to that of Figure 2, the support 1.2 now a piece of cloth 9. Note that in this figure the clamping clips do not protrude above the profile of the shoulders lateral 13 of the support.

La figure 4 est une vue en perspective du support du balai de tissu représenté sur la figure 1.Figure 4 is a perspective view of the support of the fabric broom shown in Figure 1.

La figure 5a est une vue de dessous de l'une des deux pinces d'accrochage formant leviers 5.FIG. 5a is a view from below of one of the two levitating lever clamps 5.

La figure 5c est une vue en perspective de la pince d'accrochage représentée sur la figure 5a.Figure 5c is a perspective view of the gripper shown in Figure 5a.

La figure 5b est une vue de profil de la pince d'accrochage représentée sur la figure 5a. On notera la présence, sur l'un des deux bras de levier, de trois trous 12 pour le passage des têtes de plots 14 (décrits ci-après) qui se dressent à partir de la surface supérieure du support et, sur l'autre bras de levier, un appendice laminaire élastique 11 jouant le rôle de ressort. Les tétons ou tourillons d'articulation 10 se trouvent dans une position presque centrale par rapport aux deux bras.Figure 5b is a side view of the gripper shown in Figure 5a. Note the presence, on one of the two lever arms, three holes 12 for the passage of the heads of studs 14 (described below) which stand from the upper surface of the support and on the other lever arm, an elastic laminar appendage 11 acting as a spring. The pins or articulation pins 10 are in a position almost central to both arms.

La figure 6 est une vue en perspective, prise du haut, d'une portion extrême d'un support pour un balai de tissu suivant la présente invention. Le support est dépourvu de la pince d'accrochage. On voit sur cette figure trois plots d'ancrage 14 qui se dressent à partir d'une zone creusée ou rabaissée de la surface supérieure du support. On voit également sur la figure 6 les épaulements latéraux 13 qui se dressent des deux côtés du support, avec une allure de rampe descendant vers l'extrémité. On voit, sur la partie interne de l'un des épaulements 13, un siège 19 pour l'un des deux tétons ou tourillons 10 de la pince d'accrochage formant levier non représentée.Figure 6 is a perspective view, taken from above, of an end portion of a support for a fabric broom according to the present invention. The support is devoid of the gripping pliers. This figure shows three anchor points 14 which rise from a hollowed or lowered area of the upper surface of the support. We also see in Figure 6 the lateral shoulders 13 which stand on both sides of the support, with a ramp rate down to the end. We see, on the part internal of one of the shoulders 13, a seat 19 for one of the two pins or pins 10 of the lever clamping clip not shown.

La figure 7 est une vue en perspective, prise du haut, d'une pince d'accrochage formant levier 5 non montée. On voit sur cette figure les trous 12 prévus pour le passage des plots d'ancrage 14, et les tétons ou tourillons d'articulation 10.Figure 7 is a perspective view, taken from above, of a lever fastening lever 5 unassembled. This figure shows the holes 12 provided for the passage of the anchoring studs 14, and the pins or articulation pins 10.

La figure 8 est une vue en perspective, prise du haut, de la partie extrême du support pour un balai en tissu correspondant, mais avec la pince d'accrochage 5 représentée sur la figure 6 montée en place.Figure 8 is a perspective view, taken from the top, of the end portion of the support for a corresponding fabric broom, but with the gripper 5 shown in Figure 6 mounted in place.

La figure 9 est une vue de côté du support du balai de tissu, les éléments 1,2 constituant ce support formant un angle entre eux. On voit sur cette figure que les éléments latéraux 1,2 du support sont inclinés vers le bas en étant soutenus à partir de l'élément central sur lequel ils sont articulés. Les plots d'ancrage à entailles sous-jacentes et les pinces d'accrochage formant leviers ne font pas saillie au-delà des épaulements latéraux 13 prévus dans les parties extrêmes des éléments 1 et 2.Figure 9 is a side view of the support of the cloth broom, the elements 1,2 constituting this support forming an angle between them. It can be seen in this figure that the lateral elements 1,2 of the support are inclined downwards by being supported from the central element on which they are articulated. The underlying notch anchoring studs and lever fastening clips do not protrude beyond the lateral shoulders 13 provided in the end portions of the elements 1 and 2.

La figure 10 est une vue en perspective du support du balai de tissu soutenu par un porte-manche 6 et dont les éléments latéraux 1,2 forment un angle tourné vers le bas.Figure 10 is a perspective view of the support of the fabric broom supported by a handle holder 6 and whose side members 1,2 form an angle facing downwards.

La figure 11 représente une portion de la pièce de tissu 9 à laquelle est fixé un appendice laminaire 15 pourvu de trous 16 renforcés par des oeillets. L'appendice 15 est représenté étendu vers l'extérieur.Figure 11 shows a portion of the fabric piece 9 to which is fixed a laminar appendage 15 provided with holes 16 reinforced with eyelets. Appendix 15 is shown extended outward.

La figure 12 représente la portion de la pièce de tissu 9 représentée sur la figure 11 dans le cas où l'appendice 15 pourvu des trous 16 est replié sur lui-même comme cela se produit lorsqu'il doit être inséré en dessous du bras presseur d'une pince d'accrochage 5, ce bras ayant été préalablement soulevé.FIG. 12 shows the portion of the piece of fabric 9 shown in FIG. 11 in the case where the appendix 15 provided with the holes 16 is folded back on itself as happens when it must be inserted below the pressing arm a gripper 5, this arm having been previously raised.

La figure 13 est une vue en coupe longitudinale médiane d'une portion du support du balai de tissu pourvu d'une pince d'accrochage 5. On voit sur cette figure les plots d'accrochage du support 1, l'un des épaulements latéraux 13 et le ressort 11 qui détermine l'effort de pression du bras de levier contre la surface de la partie extrême du support.FIG. 13 is a view in median longitudinal section of a portion of the support of the cloth broom provided with a hooking clamp 5. This figure shows the hooking pads of the support 1, one of the lateral shoulders 13 and the spring 11 which determines the pressure force of the lever arm against the surface of the end portion of the support.

La figure 14 est une vue correspondant à celle de la figure 13 mais avec la pince d'accrochage 5 non accouplée à la structure du support 1.FIG. 14 is a view corresponding to that of FIG. 13 but with the gripping clamp 5 not coupled to the structure of support 1.

La figure 15 est une vue, à plus grande échelle, correspondant à celle de la figure 14 et elle montre l'appendice laminaire 15, percé des trous 16 renforcés par des oeillets, de la pièce de tissu 9 disposée entre le support 1 et la pince d'accrochage formant levier 5 (cette dernière étant représentée non accouplée).FIG. 15 is a view, on a larger scale, corresponding to that of FIG. 14 and shows the laminar appendage 15, pierced with holes 16 reinforced by eyelets, of the piece of fabric 9 placed between the support 1 and the gripping clamp forming lever 5 (the latter being shown not coupled).

La figure 16 est une vue en coupe montrant schématiquement comment s'effectue l'insertion de l'appendice 15, percé des trous 16, de la pièce de tissu 9 en dessous de la pince d'accrochage formant levier 5, en étant prêt à être engagé, par l'un de ses trous 16 renforcés d'un oeillet, sur un plot d'ancrage 14 à entaille sous-jacente qui se dresse à partir de la surface du support 1.FIG. 16 is a sectional view schematically showing how the insertion of the appendage 15, pierced with the holes 16, of the piece of fabric 9 below the lever-forming gripper 5 is done, being ready to being engaged, by one of its holes 16 reinforced with an eyelet, on an anchoring stud 14 with an underlying notch which rises from the surface of the support 1.

La figure 17 représente schématiquement la phase d'insertion suivant celle qui est représentée sur la figure 16 et dans laquelle le trou 16, renforcé par un oeillet, de l'appendice laminaire 15 a été enfilé sur le plot d'ancrage 14 et engagé dans l'entaille sous-jacente présente dans la partie inférieure du plot d'ancrage 14.FIG. 17 schematically represents the insertion phase following that shown in FIG. 16 and in which the hole 16, reinforced by an eyelet, of the laminar appendage 15 has been threaded onto the anchor pad 14 and engaged in the underlying notch present in the lower part of the anchor pad 14.

La figure 18 représente schématiquement la phase (finale) qui fait suite à celle représentée sur la figure 17 et dans laquelle le bras de levier de la pince d'accrochage formant levier 5 comprime l'appendice laminaire 15 de la pièce de tissu 9 contre la surface supérieure du support. La pression exercée par le bras de levier empêche que l'appendice 15 de la pièce de tissu 9 se soulève et elle empêche en particulier que l'oeillet qui renforce le trou 16, ne se dégage de l'entaille sous-jacente du plot d'ancrage 14 auquel il est accouplé. L'empêchement du soulèvement de l'appendice 15 est déterminant quand la pièce de tissu 9 n'est pas tendue comme cela est le cas lorsque le support ne se trouve pas avec ses éléments 1-3 dans la condition de planéité (en particulier pendant la phase d'essorage).FIG. 18 schematically represents the (final) phase which follows that shown in FIG. 17 and in which the lever arm of the lever attachment clip 5 compresses the laminar appendage 15 of the piece of fabric 9 against the upper surface of the support. The pressure exerted by the lever arm prevents the appendage 15 of the piece of fabric 9 from being lifted and in particular prevents the eyelet which reinforces the hole 16 from being disengaged from the underlying notch of the stud. anchor 14 to which it is coupled. The prevention of the lifting of the appendix 15 is crucial when the piece of fabric 9 is not stretched as is the case when the support is not with its elements 1-3 in the condition of flatness (especially during the spinning phase).

Les figures 19a, 19b, 19c et 19d sont des vues respectivement de profil, de dessus, de dessous et en perspective du dessous, du bouton articulé 8 qui, en prenant appui sur le petit nez de l'élément du support contigu et opposé à celui sur lequel il se trouve être lui-même articulé, assure le maintien de la planéité des éléments 1,2,3 qui constituent le support, et qui, à la suite de son enfoncement, libère le petit nez et permet aux divers éléments 1,2,3 du support de ne plus être coplanaires. On voit sur ces figures que les tétons ou tourillons d'articulation et les branches élastiques 17 jouant le rôle de ressort forment un corps unique.FIGS. 19a, 19b, 19c and 19d are respectively views in profile, from above, from below and in perspective from below, of the hinged button 8 which, while resting on the small nose of the element of the support which is contiguous and opposite to the one on which it happens to be itself articulated, ensures the maintenance of the flatness of the elements 1,2,3 which constitute the support, and which, as a result of its depression, releases the small nose and allows the various elements 1 , 2,3 of the support to no longer be coplanar. We see in these figures that the pins or hinge pins and the elastic branches 17 acting as a spring form a single body.

La figure 20 est une vue du support correspondant à celle de la figure 9 et on voit que la pièce de tissu 9 est maintenue au moyen de ses appendices et des pinces d'accrochage formant leviers lesquelles empêchent que les oeillets des trous des appendices ne se dégagent des entailles sous-jacentes des plots d'ancrage, si bien que la pièce de tissu 9 pend librement et est prête à être essorée. Sur la figure 20 sont représentés schématiquement deux rouleaux presseurs 18 d'un appareil d'essorage qui commencent à agir en passant sur les épaulements 13 des supports 1,2. Lors de leur mouvement de descente, les rouleaux essoreurs 18 agissent d'abord sur les parties extrêmes de la pièce de tissu 9 adossées au support 1,2 puis sur sa partie pendant en dessous du support 1,2, en produisant de ce fait un essorage intégral de la totalité de la pièce de tissu 9.FIG. 20 is a view of the support corresponding to that of FIG. 9 and it can be seen that the piece of fabric 9 is held by means of its appendages and the gripping clamps forming levers which prevent the eyelets of the holes of the appendages from becoming reveal underlying notches anchor pads, so that the piece of fabric 9 hangs freely and is ready to be dewatered. FIG. 20 schematically shows two pressure rollers 18 of a dewatering apparatus which begin to act by passing over the shoulders 13 of the supports 1, 2. During their descent movement, the squeezing rollers 18 act first on the end portions of the piece of fabric 9 leaning against the support 1, 2 and then on its part under the support 1, 2, thereby producing a integral wringing of the entire piece of fabric 9.

De la description précédente ressort la validité de la présente invention qui perfectionne le système d'ancrage des parties extrêmes de la pièce de tissu 9 qui revêt le support d'un balai de tissu et qui permet, au moyen d'un appareil d'essorage à rouleaux, d'essorer la totalité de la pièce de tissu 9 y compris les parties extrêmes de cette pièce de tissu 9.From the foregoing description, the validity of the present invention which improves the anchoring system of the end portions of the piece of fabric 9 which covers the support of a fabric broom and which makes it possible, by means of a spinning apparatus, with rollers, to wring out all of the piece of fabric 9 including the end portions of this piece of cloth 9.
