Description

1-1- Indication of the technical field

The present invention relates to the domestic use of all products packaged in the form of continuous strips wound on hollow mandrels. In particular, the housewares, toilet paper, aluminum foil and films Stretchable food. Throughout this document the term "product" will cover all products packaged in the aforementioned form. For the said products the invention defines an element called "integrated mobile support" which is housed partly in space hollow mandrel of the rolls of product in order to constitute with the latter a together "mobile integrated support - product roll" intended to remain solidary up to the exhaustion of the strip of product and a second fixed element called "receiving base" intended to receive, outside periods of use, the solidarity unit mentioned above. The two constituent elements of the devices are equipped with means of securing and instant magnetic or mechanical detachments. The device aims to facilitate the use reconciling the seizure of the rolls and the product picking by manipulation free with both hands and the rest, the instant storage and fun of the said rolls as well as replenishment in new rolls.

1-2 - State of the art. 1-2-A- Case of toilet and household papers:

The study of domestic devices for the storage and distribution of toilet paper and household paper packaged in the form previously described concludes a classification of these devices into three distinct families that we will call: "repossessions," rods ", and finally "Distributors".

The "reposoirs". As their name suggests, these supports are characterized and limited to the very elementary function of reception. They induce a use according to a simple procedure: the user grasps the roll of paper on his reed, manipulates the roll with full hands to take the necessary quantity of paper, then rests the roll on the repository. These reposers offer the advantage of the free handling of the roller which is often preferred to any other device because it is the assurance of easy, comfortable, judicious and controlled removal of the amount of paper required. However these repositories are often rudimentary, unattractive, sometimes bulky or protuberant. Sometimes the absence of a specific resting place leads to the available non-specialized surfaces, such as ends of tables or pedestal tables, shelves, or even the tank of the toilet bowl to act as a "restoir".

The stems". They are different from the previous ones in that the roller is engaged on a free axis at one of its ends, leaving the roller free of rotation. These "rods" induce a use according to an apparently simple procedure: with one hand the user grasps the free end of the paper strip, unwinds the quantity that is necessary for it, blocks the roll with his other hand and then rips the paper. In the end, if we must recognize these "rods" the advantage of simplicity, they nevertheless have two major flaws: the unwinding and cutting of product are often hazardous, even sometimes problematic, and secondly they force a simultaneous mobilization of both hands that sometimes leads to contortions.

• par l'asservissement permanent du rouleau au support fixe jusqu'à l'épuisement de la bande de produit : soit le rouleau se trouve bloqué autour d'un axe, soit il se trouve enfermé dans le support, soit une force quelconque (gravité y compris) l'y maintient.
• par la non manipulation du rouleau : l'utilisateur est amené à agir le plus souvent sur la bande libre de papier.
• par l'existence de dispositifs censés assurer des assistances au déroulage, au blocage et à la découpe du papier pour permettre de prélever la quantité de papier nécessaire.

The "media-distributors". These devices can be either very basic or sometimes very sophisticated. They are all characterized:

• by the permanent slaving of the roll to the fixed support until the strip of product is exhausted: either the roll is locked around an axis, or it is enclosed in the support, or any force (gravity including) keeps it there.
• by the non-manipulation of the roll: the user is led to act most often on the free paper tape.
• the existence of devices that are supposed to provide assistance with unwinding, blocking and cutting the paper to enable the collection of the necessary amount of paper.

Usage finds that despite all the good intentions displayed and despite all the ingenuity deployed, the intended facilitation objectives are rarely achieved. Although these devices seem to work in a situation of optimum use "in the laboratory", it turns out that in the small of most toilets or in the clutter of most kitchens, and according to the implantation chosen for these devices, unwinding is often dangerous and not controlled, the blocking becomes random and the cut is finally uncertain, without mentioning the positions often inconvenient and compelling contortions that such maneuvers impose often. Finally the exasperation of the user points when it comes to the moment of need and tedious replenishment of "support-distributor" roll of new product. He is coming so often the used roll is no longer replaced. The distributor then becomes unnecessarily cumbersome and is supplanted by a "wild" practice of free rollers, often multiples that for lack of specific storage space are often abandoned on the first surface coming, even on the ground.

1-2-B - Stretch films and aluminum foil:

The packaging of the food stretch films and aluminum foils is differentiate from the packaging of paper strips by the fact that the rolls of are most often sold in cardboard packaging equipped with a device to aid distribution and cutting of the product. Therefore, the existence of a specific support does not justifies more. Yet these packages acting as distributors are most often inconvenience: difficulty in grasping the end of the sheet or film, rapid degradation cardboard packaging, inefficiency of the cutting aid device. To mitigate these inconvenience, specific media appeared on the mainstream market. Whether they are of the type "restoir", "rod" or "distributor" can be renewed against them the grievances cited previously about paper roll holders. Some effective devices, are available, but their characteristics are foremost for professionals.

1-3 - Presentation

Un élément appelé "support intégré mobile" dispose des caractéristiques suivantes :

• sa forme et ses dimensions lui permettent de se loger pour partie dans le vide axial défini par le mandrin creux d'un rouleau de produit.
• il est équipé d'un dispositif permettant sa solidarisation instantanée et ferme durant le temps d'usage de la bande en prenant notamment appui sur la face interne du mandrin creux du dit rouleau de produit et sa désolidarisation rapide et aisée avec un rouleau de produit.
• sa présence au sein d'un rouleau de produit n'empêche pas l'utilisateur d'accéder librement à l'espace interne défini par le mandrin creux du rouleau de produit ou à défaut laisse libre un espace axial d'une dimension suffisante permettant à l'utilisateur de glisser au moins un doigt dans chacune des extrémités du mandrin creux.
• aucune de ses caractéristiques techniques ou formelles ne gêne le prélèvement de produit sur le rouleau dans lequel est logé cet élément.
• une de ses extrémités au moins est équipée d'un dispositif de solidarisation temporaire magnétique ou par fibre de type VELCRO marque déposée avec un élément fixe appelé "socle de réception" équipé du dispositif de solidarisation temporaire complémentaire. Fixé sur une surface d'accueil, ce dit "socle de réception" est le point de rangement de l'ensemble "rouleau de produit-support intégré mobile" après chaque utilisation.

Ces caractéristiques remplies le recours à l'invention se déroule sur un mode opératoire évident lors de chaque utilisation : Dès lors que l'utilisateur potentiel s'est assuré que le support intégré mobile est approvisionné en produit, l'utilisateur saisit le rouleau d'une main. Par traction élémentaire l'utilisateur désolidarise du socle de réception sur lequel il repose l'ensemble solidaire "rouleau de produit-support intégré mobile". L'utilisateur manipule le rouleau à pleines mains, prélève la quantité de produit qui lui est nécessaire puis approche l'ensemble "rouleau-support intégré" du socle de réception. Grâce à des dispositifs de solidarisations mutuels magnétiques ou mécaniques le socle de réception et le support intégré mobile se solidarisent l'un à l'autre instantanément sans attention particulière de la part de l'utilisateur. Lorsque le rouleau est périmé, le réapprovisionnement du support intégré mobile avec un rouleau neuf est une opération simple : déblocage et dégagement du rouleau périmé du support intégré mobile par tractions simples exercées dans des sens opposés suivi de l'engagement et du blocage instantané d'un nouveau rouleau sur le dit support mobile.

To ensure the desired features, the device presented here is as simple as possible. It does not belong to any of the families of devices mentioned above. Nevertheless by its simplicity it is close to the family of "reposoirs". Like the representatives of this family, the device according to the invention does not offer any assistance with sampling and cutting of products. With the notable exception of a single mixed version, it provides, during each use, a free handling and full hands of the roller to allow a product picking convenient, fast, effective and controlled by everyone according to techniques various, varied and especially personal. It distinguishes itself in particular by avoiding the common disadvantages to this last category of devices. Indeed according to the invention the size of the device is minimized because it is largely integrated with the roller. The capture, the release, the rest of the roll are made instantaneous and without delicate gestural adjustment through the use of magnets or fibers type VELCRO, registered trademark. Finally, the device adds a playful and even magical dimension: the roll is kept "as if by magic" on its reception area. In order to satisfy these objectives, the device according to the invention has the following characteristics and principles:

An element called "integrated mobile support" has the following characteristics:

• its shape and dimensions allow it to be partly housed in the axial void defined by the hollow mandrel of a roll of product.
• it is equipped with a device for its instantaneous and firm fastening during the time of use of the tape by taking particular support on the inner face of the hollow mandrel of said product roll and its fast and easy separation with a roll of product.
• its presence within a roll of product does not prevent the user from having free access to the internal space defined by the hollow mandrel of the roll of product or else leaves free an axial space of sufficient size the user to slide at least one finger into each end of the hollow mandrel.
• none of its technical or formal characteristics hinders the collection of product on the roller in which this element is housed.
• at least one of its ends is equipped with a temporary magnetic fastening device or VELCRO type trademarked fiber with a fixed element called "receiving base" equipped with complementary temporary fastening device. Attached to a receiving surface, this "receiving pedestal" is the storage point for the "mobile integrated support-product roller" assembly after each use.

These characteristics fulfilled the recourse to the invention takes place on an obvious operating mode during each use: As soon as the potential user has made sure that the integrated mobile support is supplied with product, the user grasps the roll of a hand. By elementary traction the user disconnects from the receiving base on which he rests the integral assembly "roll of product-mobile integrated support". The user manipulates the roll with full hands, takes the quantity of product which is necessary for him and then approaches the set "roll-integrated support" of the base of reception. By means of mutual magnetic or mechanical solidarization devices the receiving base and the integrated mobile support are solidly attached to one another instantly without any particular attention on the part of the user. When the roll is out of date, replenishing the movable integrated support with a new roll is a simple operation: unlocking and releasing the expired roll of the movable integrated support by simple pulls exerted in opposite directions followed by the engagement and the instantaneous blocking. a new roll on said mobile support.

1-5 - A - Reference embodiment:

• Une de ses faces est équipée d'un revêtement adhésif ou de tout autre disposition permettant la fixation de la dite plaque mince (11) de manière ferme sur une surface que l'on appellera surface d'accueil (9) indifféremment verticale, oblique ou horizontale.
• L'autre face, plane, est garnie d'un parement métallique (3) sensible à la force magnétique des aimants courants.

Support fitted to a mandrel: With reference to FIGS. 2, 3, 4, 5 and 36 The receiving base (1): The receiving base (1) consists of a thin plate (11) of suitable material, satisfying two conditions:

• One of its faces is equipped with an adhesive coating or any other arrangement allowing the fixing of said thin plate (11) firmly on a surface that will be called receiving surface (9) indifferently vertical, oblique or horizontal.
• The other face, flat, is lined with a metal facing (3) sensitive to the magnetic force of the current magnets.

These two conditions can be met by the same element if said thin plate (11) is it itself metal material (3) sensitive to the magnetic force of the current magnets. In its lower part, the thin plate (11) may have a relief (15) serving as support.

The integrated mobile support (2): The integrated mobile support (2) takes the form of a truncated cone (13) slightly flared. Its center is hollowed out along its axis and forms the largest hollow cylinder possible. The size of said truncated cone (13) is determined in relation to the inner diameter of the hollow mandrel (6) of the product roll (7) to be fixed: the smallest outside diameter of said truncated cone (13) slightly smaller than the inner diameter of said hollow mandrel (6), and largest outer diameter of said truncated cone (13) slightly greater than the inner diameter of said hollow mandrel (6). The plastic or any other appropriate semi-rigid material constituting said truncated cone (13) is chosen for its elastic qualities allowing slight deformations. The total introduction and the slight forcing said truncated cone (13) in the hollow mandrel (6) causes the firm wedging of said truncated cone (13) in said hollow mandrel (6). The non-slip material (12) or deformable reliefs (22) present on the outer face of the truncated cone (13) reinforce the temporary joining of the two said elements (6-13). At its widest end, the truncated cone (13) widens perpendicularly to its axis and outwardly in the form of a ring (4) which will be called contact extension (4). The flat outer face of said contact extension (4) will be called contact surface (25). This said contact surface (25) is coated on all or part of its area with a material (3a) or includes in its masses a material (3a) developing a magnetic attraction force on the metal facing material ( 3) of the thin plate (11) of the receiving base (1).

For the user, the magnetic connection of the mobile integrated support (2) on the base of reception (1) is instantaneous as soon as the contact surface (25) of the mobile integrated support (2) is approached to the thin plate (11) of the receiving base (1). The separation of the support integrated mobile (2) of the reception base (1) is also instantaneous as soon as a light traction is exerted on the roll of product (7) secured to the movable integrated support (2).

Note No. 1: The objective of temporary and infinitely repeatable joining of the mobile integrated support (2) on the receiving base (1) can be similarly satisfied by reversing the distribution of the characteristics of the thin plate (11) and of the contact surface (25): in this case the receiving base (1) is lined with a coating (3) capable of developing a magnetic attraction force towards the metal face (3a) of the contact surface (25).

• premièrement : solidarisation par coincement ferme entre le support intégré mobile (2) d'une part et un rouleau de produit (7). Le décoincement doit être par ailleurs aisé par tractions simples exercées dans des sens opposés sur le rouleau (7) d'une part et sur le prolongement de contact (4) d'autre part.
• dexièmement : solidarisations mutuelles instantanées temporaires et répétables à l'infini entre d'une part le socle de réception (1) et le support intégré mobile (2) porteur d'un rouleau de produit (7). Remarque N°3 : Pour que le dispositif selon l'invention remplisse les fonctions pour lesquelles il est destiné, il est indispensable que les forces qui assurent les deux fonctionalités précédemment rappelées soient d'intensités cohérentes ce qui peut se résumer ainsi : la force de coincement du support intégré mobile (2) avec la face interne du mandrin creux (6) du rouleau de produit (7) doit être supérieure à la force de résistance à l'arrachement liant le socle de réception (1) au support intégré mobile (2).

Note 2: The materials, dimensions, weights, and other technical or formal characteristics of all components of the receiving pedestal (1) and the mobile integrated support (2) are defined to ensure and optimize both functionalities complementary features of the device namely:

• firstly: secured by firm wedging between the mobile integrated support (2) on the one hand and a product roll (7). The detachment must also be easy by simple pulls exerted in opposite directions on the roller (7) on the one hand and the contact extension (4) on the other hand.
• secondly: temporary instantaneous and infinitely repeatable mutual interdependences between the receiving pedestal (1) and the mobile integrated support (2) carrying a product roll (7). Note No. 3: In order for the device according to the invention to perform the functions for which it is intended, it is essential that the forces which provide the two previously recalled functionalities be of coherent intensities, which can be summarized as follows: the force of wedging of the movable integrated support (2) with the inner face of the hollow mandrel (6) of the product roll (7) must be greater than the tear resistance force linking the receiving base (1) to the movable integrated support ( 2).

Note No. 4 : It is agreed that the preceding remarks No. 1, No. 2 and No. 3 are applicable to all the embodiments described in this document and to all their variants.

Variant: fiber bonding type VELCRO. registered trademark or similar fibers. With reference to Figures 2 to 5.

The function of joining and disconnecting between the receiving base (1) and the support integrated mobile (2) can be similarly ensured by using "type" fibers VELCRO "Under the trademark VELCRO are indeed defined the characteristics of two types of complementary fibers endowed with specific capacities. The distribution distinct from the two types of fiber that we will call males for some, and females for the others, on two different tissues endows its two fabrics with solidarization capabilities and infinite fast mutual dissociations. The variant to the reference model consists of counter the outer face of the thin plate (11) of the receiving base (1) with a typical coating VELCRO male or female (3) and to coat the contact surface (25) of the contact extension (4) a cladding VELCRO type (3a) male or female, complementary to the first.

Note No. 5: It will be understood that this variant using fibers "VELCRO type" will be applicable to all the magnetic models described in this document.

1 - 5 - B - Other embodiments . 1 -5-Ba: adjustable ring holder. With reference to Figures 6 to 16.

Receiving base (1): unchanged, see description, reference model paragraph 1-5-A.

The integrated mobile support (2) is constituted on the basis of a hollow tube of small thickness, suitable elastic material, of a minimum length of a few centimeters and in diameter outside very slightly greater than the inside diameter of the hollow mandrel (6) of the roll of product (7) to be fixed. Closer to one of its ends the hollow tube is cut transversely over at least two thirds of its section delimiting two sections. At the narrowest section of hollow tube is secured a ring (4) which will be named extension contact (4) whose planar outer face will be called contact surface (25). This said contact surface (25) is coated on all or part of its area with a material (3a) or includes in its masses a material (3a) developing a magnetic attraction force on the metal facing (3) of the thin plate (11) of the receiving base (1). In contrast to the connecting part still joining the two sections of the hollow tube, the widest section is cut longitudinally over at least one twentieth of its circumference to form a incomplete ring (14). The free ends of this so-called incomplete ring (14) can be compressed to be approached from each other under the action of external forces centripetal. Thus in a compressed position, the said incomplete ring (14) can be introduced into the hollow mandrel (6) of the product roll (7) to be fixed. When in this position the forces exterior compression are eliminated, the elastic qualities of the material allow the said incomplete ring (14) to regain its initial dimension rendering said ring incomplete (14) integral with the product roll (7) due to the friction forces caused. These forces are reinforced by the addition of anti-slip material (12) or reliefs (22) on the outer face of the incomplete ring (14).

1 -5-Bb: spring leaf holder. With reference to Figures 17 to 23. Receiving base (1): unchanged, see description, reference model paragraph 1-5-A.

The integrated mobile support (2) develops from a hollow tube-shaped structure (8) thin, with an inside diameter large enough to accommodate minus one finger and with an outside diameter small enough to allow it to be introduced into the internal space defined by the hollow mandrels (6) of the product rolls (7). At one of his ends, the hollow tube (8) thickens perpendicular to its axis to form a ring (4) which will be called contact extension (4). The flat outer face of this says extension of contact will be named contact surface (25). This so-called contact surface (25) is coated on all or part of its area with a material (3a) or includes in its masses a material (3a) developing a magnetic attraction force towards the metallic material facing (3) of the thin plate (11) of the receiving base (1). The hollow tube (8) is equipped at least three elastic spring blades (5) regularly distributed around its periphery. These said spring blades (5) are formed either on the side of the hollow tube (8) or from the end opposite to the contact extension (4). In the latter case the blades can either extend the hollow tube (8) (FIGS. 17, 18 and 29 to 34) should either turn and move towards the contact extension (4) (FIGS. 19, 20, 21, 22 and 23). These so-called blades spring (5) may be an extension of the constituent material of the hollow tube (8) or may be elements reported and stuck on the hollow tube (8).

• que ces dites lames à ressort (5) sont facilement comprimables et que dans la configuration de compression maximale elles développent une section plus petite que la plus petite section courante des mandrins creux (6) des rouleaux de produit (7) afin de rendre possible leur engagement ainsi que celui du support intégré mobile dans l'espace interne défini par les dits mandrins creux (6) des rouleaux de produit (7).
• qu'ainsi placées au sein d'un mandrin creux (6) et hors de toute action extérieure, ces dites lames à ressort (5) développent une force centrifuge capable, en agissant par frottement sur la face interne du dit mandrin creux (6) d'un rouleau de produit (7), de bloquer le dit rouleau de produit (7) afin de rendre fermement solidaire l'ensemble "tube creux (8) - rouleau de produit (7)".
• qu'à la volonté de l'utilisateur, le rouleau de produit (7) peut être aisément désolidarisé du tube creux (8) par tractions exercées dans des sens opposées sur le dit rouleau de produit (7) d'une part et sur le prolongements de contact (4) d'autre part. Afin de renforcer la sotidarisation par coincement du tube creux (8) contre la face interne du mandrin creux (6) les lames à ressort (5) sont garnies de matériau agrippant (12), et présentent des aspérités (22) ou tout autre relief (22) visant à assurer un meilleur contact et une meilleure retenue du mandrin creux (6) par augmentation des forces de frottement

Whatever their placements, materials and orientations, said spring blades (5) are arranged so that:

• in the absence of external forces, said spring blades (5) develop a section wider than the largest running section of the hollow mandrels (6) of the product rolls (7).
• that said spring blades (5) are easily compressible and that in the maximum compression configuration they develop a smaller section than the smallest running section of the hollow mandrels (6) of the product rolls (7) to make possible their engagement as well as that of the integrated mobile support in the internal space defined by said hollow mandrels (6) of the product rolls (7).
• that thus placed within a hollow mandrel (6) and out of any external action, these said spring blades (5) develop a centrifugal force capable, acting by friction on the inner face of said hollow mandrel (6) a product roll (7), blocking said product roll (7) to firmly secure the assembly "hollow tube (8) - product roll (7)".
• at the will of the user, the product roll (7) can be easily separated from the hollow tube (8) by pulling in opposite directions on the product roll (7) on the one hand and on the contact extensions (4) on the other hand. In order to reinforce the sotidarisation by wedging of the hollow tube (8) against the inner face of the hollow mandrel (6), the spring blades (5) are lined with gripping material (12), and have asperities (22) or any other relief (22) to provide better contact and retention of the hollow mandrel (6) by increasing frictional forces

Remaraue No. 6: Referring to Figures No. 17 and No. 18 and No. 29 to No. 34. When the spring blades (5) are directed towards the open end of said hollow tube (8), said hollow tube (8) has, on its external face and at the level of the contact extension (4), a progressive widening ( 10) arranged such that it provides, regardless of the inner diameter of the hollow mandrel (6), an additional point of contact between the hollow tube (8) and the hollow mandrel (6).

1-5-Bc: rotating support With reference to FIGS. 24 to 28

This model is an evolution of the model described in the previous paragraph: 1-5-B-b. he allows to add a rotation function to the functions already described.

Receiving base (1): unchanged, see description, reference model paragraph 1-5-A.

The integrated mobile support (2) develops from a hollow tube-shaped structure (8) similar to that described in paragraph 1-5-B-b. This hollow tube (8) nevertheless differs by two evolutions: on the one hand the template of said hollow tube (8) -internal diameters and outside-is here slightly lower than that described in paragraph 1-5-B-b and on the other hand, the opposite end to the contact extension (4), the hollow tube (8) thickens on the outside and perpendicular to its axis to form a ring of low height that we will name stop (4a). A secondary hollow tube (8a) of small thickness concentrically surrounds the hollow tube (8) initial. This said hollow secondary tube (8bis), free to rotate around the tube hollow (8), is blocked laterally by the stop (4a) on the one hand and by the extension contact (4) on the other hand. On the circumference of the secondary hollow tube (8a) are distributed at least three spring blades (5) resiliently compressible. These so-called blades elastic spring (5) are arranged in the same and have the same characteristics than those described in paragraph 1-5-B-b or in the variant described in the same paragraph. In addition to the functions already described, this arrangement allows the free rotation of a together constituted by the secondary hollow tube (8a) and the product roll (7) blocked by the spring blades (5) around the initial hollow tube (8).

Note No. 7 : This evolution incorporating a secondary tube (8bis) freely rotating around the initial tube (8) is applicable to the models described in the preceding paragraphs: 1-5-A and 1-5-Ba and 1-5-Bb.

1-5-B-d: eccentric mandrel With reference to Figures 35 to 50;

Receiving base (1): unchanged, see description, reference model paragraph 1-5-A.

• laissent libre l'accès à l'espace interne défini par les faces internes des mâchoires (206) afin que l'utilisateur y glisse au moins un doigt,
• ne gênent pas les mouvements de rapprochement ou d'écartement des bords libres (213) des mâchoires (206),
• offrent chacun sur leur face extérieure une surface plane suffisamment grande appartenant à un même plan, que l'on nommera surfaces de contact (25). Ces dites surfaces de contact (25) sont revêtues sur tout ou partie de leur aire d'un matériau (3 bis) ou incluent dans leurs masses un matériau (3 bis) développant une force magnétique d'attraction sur le matériau de parement (3) de la plaque mince (11) du socle de réception (1).

The integrated mobile support (2). The body of the mobile integrated support (2) is comparable to an eccentric hollow mandrel. It is constituted by the union of two elements, similar or not, in the form of portions of hollow cylinders that will be called jaws (206). The said jaws (206) are assembled to one another over all or part of one of their lengths by hinges (207) and pivot about a non-axial longitudinal common axis (208). Thus connected, said jaws (206) recomposed, when their free edges (213) are close together, a hollow cylinder almost complete. The dimensions of the jaws (206), the arrangement of the hinges (207) and the position of the axis of rotation (208) are such that, when assembled, when their free edges (213) are approached against each other. other, said jaws (206) can be engaged together in the internal space defined by the hollow mandrel (6) of a product roll (7). The inner faces of the jaws (206) and the axis of rotation (208) are provided with spacers (212) such that in the absence of external forces, the free edges (213) of the two jaws (206) ) are separated and widely separated from each other. The approximation of the free edges (213) of the jaws (206) is possible only with the recourse to external forces exerted in a centripetal direction on the external faces of the jaws (206) and whose sum of the intensities is greater than the sum of the intensities of the centrifugal forces of the spacers (212) which bear on the axis of rotation (208) or on the internal faces of the jaws (206). Thus dimensioned and out of actions of external forces, the jaws (206) spaced from one another by the spacers (212), exert, when they are positioned in the internal space defined by the hollow mandrel (6) a product roll (7) a centrifugal pressure on the inner face of the hollow mandrel (6) of the product roll (7) and consequently ensures a connection between the jaws (206) and the roll of product (7). This fastening will be all the more firm as the spacing device (212) will develop a powerful force and that the outer faces of the jaws will be coated with gripping material, anti-slip (12) or any other device increasing the friction resistance between the two surfaces. At one of their common ends, and perpendicular to their length, each of two jaws (206) is integrally extended by an element (4) which will be called contact extension (4). Of arbitrary and not necessarily similar shapes, these so-called contact extensions (4):

• leave free access to the internal space defined by the inner faces of the jaws (206) so that the user slides therein at least one finger,
• do not interfere with the movement of the free edges (213) of the jaws (206) towards or away from each other,
• each have on their outer surface a sufficiently large flat surface belonging to the same plane, which will be called contact surfaces (25). These said contact surfaces (25) are coated on all or part of their area with a material (3a) or include in their masses a material (3a) developing a magnetic attraction force on the facing material (3a). ) of the thin plate (11) of the receiving base (1).

Variant 1: With reference to FIGS. 51 to 53, the contact extensions (4) may not lie in the same frontal plane, one being then in front of the other. In this case, only the contact surface (25) of the outermost contact extension (4) is coated on all or part of its area with a material (3a) or includes in its mass a material (3a) developing a magnetic attraction force on the facing material (3) of the thin plate (11) of the receiving base (1). This variant of the embodiment makes it possible to obtain a single contact surface (25) guaranteeing more secure connections between the mobile integrated support (2) and the receiving base (1). The dimensions and the shape of the outermost contact extension (4) are such that they do not interfere with the gripping of the internal contact extension (4) in order to act freely on the opening of the jaws (206).

Device according to claim 1, characterized in that the movable integrated support (2) housed and secured in the internal space defined by the hollow mandrel (6) of a product roll (7) leaves at each end of said mandrel hollow (6) is a total access to said internal space is a partial access but of sufficient size to allow the user to slide at least one finger. Device according to claims 1 and 2, characterized in that the movable integrated support (2) takes the form of a cone-shaped truncated cone (13), the largest diameter of which is very slightly greater than the inside diameter of the hollow mandrel (6). roll of product (7) in which it must be housed and whose semi-rigid material allows slight deformations thus allowing firm entrapment of said movable integrated support (2) against the inner face of said hollow mandrel (6) when said trunk cone (13) is completely introduced into the central void of said hollow mandrel (6), this jamming extending throughout the time of use of the product roll (7). Device according to claims 1 and 2, characterized in that the body of the movable integrated support (2) takes the form of an incomplete elastic ring (14) whose diameter is greater than the inside diameter of the hollow mandrel (6) of the roll of product (7) to fix but likely thanks to the elastic qualities of its material to be compressed under the action of external centripetal forces so that its diameter becomes smaller than the inner diameter of said hollow mandrel (6) making possible the introduction of said incomplete ring (14) in the central void of said hollow mandrel (6) so as to make said elements (6 and 14) firmly joined by friction as soon as the external forces cease. Device according to claims 1 and 2, characterized in that spring blades (5) or resilient preformed blades (30) mounted on the body or at the end of the hollow tube (8) constituting the movable integrated support (2) develop at rest a large section greater than the inside diameter of a hollow mandrel (6) of the product roll (7) and are arranged such that when centripetal external forces compress said elastic blades (5 or 30) said blades elastic members (5 or 30) develop a large section smaller than the inner diameter of the hollow mandrel (6) of a product roll (7) so that the movable integrated support (2) can be introduced into the central void of said hollow mandrel (6) and that, in this position, when the external forces cease, the elastic qualities of the spring blades (5) or preformed blades (30) tend to return to said blades (5 or 30) their original section and solidarize thus firmly the mobile integrated support (2) to the hollow mandrel (6) through the friction exerted on the inner face of said hollow mandrel (6). Device according to claims 1 and 2, characterized in that the movable integrated support (2) consists of two moving parts called jaws (206) which pivot about a non-axial longitudinal common axis (208) and which are subjected to the action of spring devices (212) exerting spacing forces, is comparable to an eccentric hollow mandrel whose total dimensions allow, when the free edges (213) of the jaws (206) are approached from one another, inserting said movable integrated support (2) into the hollow mandrel (6) of a product roll and whose spring device (212) allows, out of actions of any contrary external force, to discard and pressing the jaws (206) sufficiently strongly against the inner face of the hollow mandrel (6) thus generating sufficient friction to firmly secure the movable integrated support (2) and the hollow mandrel (6)). Device according to claims 1 and 2 and according to one of claims 3 or 4 or 5 or 6 characterized in that a relief (15) serving as a support for the product roll (7) completes the base portion of the receiving pedestal (1).
