Description

[0001] DESCRIPTION

[0002] TITLE: TAPE APPLYING DEVICE

[0003] Technical field of the invention

[0004] The present invention relates to a device for applying a strip to a joint between two panels.

[0005] When building a wall, panels, such as plasterboard, may be arranged in a row to form the wall. Such panels usually have a tapered edge, corresponding to a reduction in the thickness of the panel at one end edge. Thus, the contact of two tapered edges of two panels forms a joint.

[0006] Such a joint needs to be covered so that it is not visible once the wall construction is finished. Covering such a joint has, among other things, a waterproofing aspect of the wall and an aesthetic aspect. Thus, it is common to use strips of paper, for example, to cover the panel joints.

[0007] The installation of panel joint strips consists in particular of a step of filling the joint with a coating, then a step during which the strip is placed on the fresh coating, then a step of tightening the strip, that is to say a step during which the strip is pressed against the fresh coating in order to expel the air and excess coating under it, then a step of recovering the excess coating. Subsequently the strip is again covered with the same coating which will have to be smoothed.

[0008] When applying the strip, it is necessary to ensure that the strip is properly applied to the plaster while removing excess plaster from the joint and the panels, which could create irregularities on the wall once finished. These steps are tedious and require numerous operations and manipulations by an operator. Also, these steps require numerous tools and their use on panels of a significant height can be complex.

[0009] Thus, the invention proposes to solve the aforementioned problem by making it possible to simplify the installation of the strip at the joint of plasterboards. In particular, the invention proposes a device making it possible to carry out the step of tightening the strip and scraping off the excess plaster simultaneously and with a single device.

[0010] Summary of the invention

[0011] The invention proposes a device for applying a strip arranged at the junction of two panels, the application device comprising at least: a plate which extends in a main longitudinal and transverse plane, the plate comprising at least one scraping member,

[0012] - the scraping member comprising at least one blade which extends in a plane intersecting the main plane of the plate,

[0013] - a roller secured to the plate via fixing means allowing the rotation of the roller around a transverse axis of rotation, the roller and the scraping member extending on the same side of the plate, the roller having the shape of double cones of revolution whose bases are in full contact with each other.

[0014] According to other characteristics of the invention:

[0016] - the scraping member comprises two wings which extend on either side of the blade, from its transverse end edge and such that the wings extend in a plane intersecting the main plane of the platen and the plane of the blade of the scraping member, and in the direction of the roller; - the transverse end edge of the blade of the scraping member extends along a first transverse dimension and the roller extends along a second transverse dimension, the first transverse dimension being greater than the second transverse dimension;

[0017] - the device comprises at least one stop member which extends from the plate towards the blade of the scraping member;

[0018] - the at least one stop member comprises a means of attachment to the plate allowing the vertical movement of said stop member and the holding in position of said stop member;

[0019] - at least the fixing edge of the blade is elastically deformable;

[0020] The invention also relates to an assembly for applying a strip arranged at the junction of two panels, the assembly comprising at least one application device according to any one of the preceding characteristics and a support configured to be fixed to a reservoir of a bonding element, the support comprising a guide surface configured to receive and guide the roller of the application device in rotation, and comprising a scraping wall which extends in a plane intersecting the guide surface and configured to receive the blade of the scraping member when the roller is guided by the guide surface.

[0021] According to a characteristic of the invention, the support comprises ears for fixing to the tank, the guide surface and the scraping wall being aligned along a first straight line and the fixing ears extending along a second straight line intersecting the first straight line.

[0031] Detailed description of the invention

[0032] For the description of the invention and the understanding of the claims, the vertical, longitudinal and transverse orientations according to the reference V, L, T indicated in the figures, the longitudinal L and transverse T axes of which extend in a horizontal plane, will be adopted as a non-limiting example and without limiting reference to Earth's gravity. By convention, the longitudinal axis L is oriented from rear to front.

[0033] In the following description, identical, similar or analogous elements will be designated by the same reference numbers.

[0034] Figure 1 illustrates an assembly 10 for applying a strip 12 to a joint 14 between two panels 16, for example of a wall. The two panels 16 may be, for example and in a non-limiting manner, plasterboards commonly used in building construction and may, for example and in a non-limiting manner, have a thinned edge 17. By thinned edges 17 is meant a reduction in the thickness of the panels 16. Thus, the joint 14 between the two panels 16 corresponds to the contact of the edge 17, for example thinned, of each of the panels 16. It is then understood that the thinned edges form a groove between the two panels 16 corresponding to the joint 14.

[0035] Such a joint 14 between the two panels 16 needs to be covered to form a smooth and continuous area. Thus, it is usual to arrange the strip 12, for example of paper, covering the joint 14. To do this, a coating for sticking the strip 12 is used.

[0036] The method of applying the strip 12 will be detailed later in the detailed description.

[0037] In order to apply the strip 12 covering the joint 14, the application assembly 10 according to the example of the invention illustrated can be advantageously used.

[0038] The application assembly 10 then comprises at least one application device 18 and a support 20 configured to be fixed to a reservoir 22 of a bonding element, for example a reservoir 22 for the coating, mentioned previously.

[0039] The application device 18, particularly visible in Figures 2 to 5, comprises at least one plate 24 which extends in a main longitudinal plane P L and transverse plane T and which forms a main body of the application device 18. It is therefore understood that the plate 24 forms a flat surface of which a first side 26 and a second side 28 opposite one another are defined in a vertical direction V.

[0040] In the remainder of the description, the first side 26 will be defined as being the side intended to be opposite the strip when using the application device 18 and the second side 28 as being the side intended to be opposite the strip, i.e. facing an operator of the application device 18.

[0041] The application device 18 according to the example of the invention illustrated comprises at least one roller 30 and a scraping member 32.

[0042] More precisely, the plate 24 comprises at least a first light 34 and a second light 36. Light is understood to mean a through opening in a thickness of the plate. The first light 34 and the second light 36 have a substantially quadrilateral shape.

[0043] By defining two equal parts of the plate 24, that is to say mirrors of each other, along a secant plane S transverse T and vertical V, the first light 34 and the second light 36 are formed in the plate 24, in the same part of the latter, then called first part 38 of the plate 24.

[0044] In the remainder of the description, an advantageous embodiment will be described in which the particular shape of the plate is produced by cutting and folding a piece of sheet metal. This embodiment advantageously makes it possible to obtain a plate with optimal strength since it is made from a single piece.

[0045] It is further understood that this advantageous embodiment is not limiting and that the plate can be produced by any other means, for example by molding.

[0046] As seen in Figure 2, the first light 34 is formed by cutting the plate 24 in such a way as to form a rectangular tab 40, seen in Figure 3, then by deformation of said tab 40. In other words, the plate 24 is cut in such a way as to form three U-shaped inner edges 42 and a tab 40 resulting from the cutting of the three inner edges 42.

[0047] The tongue 40 of substantially rectangular shape is subsequently deformed such that it extends in a plane intersecting the main plane P of the plate 24 and through the first light 38.

[0048] It is then understood that the tongue 40 is secured to the plate 24 by a connecting edge 44 which extends transversely on the plate 24 and longitudinally opposite one of the inner edges 42 of the first light 34 which extends transversely.

[0049] The scraping member 32 comprises at least one blade 46 which extends in a plane intersecting the main plane P of the plate 24. The blade 46 comprises in particular a fixing edge 48, visible in FIG. 3, and a transverse end edge 50, opposite one another in a direction of main elongation of the blade 46. The fixing edge 48 of the blade 46 corresponds in particular to the edge of the blade 46 secured to the tongue 40 mentioned above.

[0050] According to a non-limiting example of the invention, the fixing edge 48 of the blade 46 and the tab 40 can be secured to each other by screwing, riveting or clipping.

[0051] The blade 46 thus extends in a common plane with the tongue 40 and in a direction longitudinally opposite to the second slot 36, that is to say in such a way as to extend opposite a second part 52 of the plate 24, longitudinally opposite to the first part 38 of the plate 24 mentioned previously.

[0052] The scraping member 32 also extends opposite, at least in part, the first side 26 of the plate 24.

[0053] It is then understood that the transverse end edge 50 of the blade 46 is intended to come into contact with the strip when using the application device 18.

[0054] According to a non-limiting characteristic of the invention, the transverse end edge 50 of the blade 46 extends over a first transverse dimension DT1 visible in FIG. 4 and between 100mm and 150mm. According to an advantageous example, the first transverse dimension DT1 is equal to 125mm.

[0055] The scraping member 32 further comprises at least two wings 54 which extend on either side of the blade 46 in the transverse direction T, from its transverse end edge 50 and such that the wings 54 extend in a plane intersecting the main plane P of the plate 24 and the plane of the blade 46 of the scraping member 32. The wings 54 extend in particular towards the roller 30.

[0056] Thus, when using the application device 18, the transverse end edge 50 of the blade 46 is intended to remove the excess coating on and around the strip and the wings 54 which they carry make it possible to channel the coating in order to facilitate its recovery.

[0057] According to an example of the invention, at least the fixing edge 48 of the blade 46 is elastically deformable. By elastically deformable is meant the fact that the fixing edge 48 is capable of deforming and returning to its initial undeformed state without breaking its material. It is then understood that such a characteristic allows the blade 46 to be more flexible during use of the application device 18 and to resist pressure exerted by an operator with the objective of pressing the transverse end edge 50 against the strip.

[0058] It is further understood that the elastic deformation of the fixing edge 48 of the blade 46 moves the latter towards the first side 26 of the plate 24 so as to reduce a vertical space which separates them.

[0059] Therefore, according to an example of the invention, the application device 18 comprises at least one stop member 56 which extends from the plate 24 towards the blade 46 of the scraping member 32.

[0060] More precisely, the stop member 56 can take the form of a screw 56a passing vertically through an orifice formed in the plate 24 and locked in position by two nuts 56b arranged on either side of the plate 24 in the vertical direction V. It is then understood that the stop member 56 according to the example of the invention extends on the first side 26 and on the second side 28 of the plate 24.

[0061] The stop member 56 then comprises a damping element 56c arranged at one end of the screw 56a which extends on the first side 26 of the plate 24, opposite the blade 46 of the scraping member 32.

[0062] The damping element 56c may be, for example and in a non-limiting manner, a lug made of a flexible material such as rubber.

[0063] The stop member 56 is furthermore arranged in the second part 52 of the plate 24 so as to extend opposite the blade 46 of the scraping member 32.

[0064] It is then understood that the stop member 56 as described can be moved vertically through the orifice of the plate 24, and that the nuts 56b ensure that the screw 56a is held in position through the orifice.

[0065] According to an advantageous example of the invention, the application device 18 comprises two stop members 56 according to the above characteristics, the stop members 56 being aligned along a transverse straight line T.

[0066] Thus, advantage is taken of such stop members 56 each formed by a screw 56a and two nuts 56b, in that they can be adjusted vertically. Thus, the stop members 56 form a support for the blade 46 of the scraper member 32 during the deformation of the fixing edge 48 during the use of the application device 18 and thus ensure the stability of the transverse end edge 50 of the blade 46 during its passage at least over the strip.

[0067] In other words, the two stop members 56 as just described limit the transverse and vertical deformation of the blade 46 during use of the application device 18 so that the transverse end edge 50 is continuously in contact at least with the strip, over its entire surface. The two stop members 56 also allow the parallel alignment of the wing 54 with the panel 16. This improves the scraping of the coating.

[0068] The second lumen 36 of the plate 24 is formed such that the first lumen 34 extends longitudinally between the second lumen 36 and the second portion 52 of the plate 24.

[0069] The second slot 38 is formed by cutting the plate 24 along two straight lines parallel to the transverse direction T, so as to form two internal edges 58 of the second slot 38. Subsequently, the portion of the plate 24 extending between the two internal edges 58 is cut longitudinally so as to form two fixing tabs 60.

[0070] More precisely, the fixing tabs 60 are folded at a longitudinal connecting edge 62 with the plate 24 in order to each extend in a longitudinal plane L and vertical plane V, thus forming the second slot 36 of the plate 24.

[0071] The fixing lugs 60 also extend towards the first side 26 of the plate 24.

[0072] It is then understood that the second lumen 36 is formed by the two internal edges 58 which extend transversely opposite one another, and by the two longitudinal connecting edges 62 of the fixing lugs 60, said longitudinal connecting edges 62 longitudinally connecting the internal edges 58 to one another.

[0073] As particularly visible in Figure 2, the roller 30 extends opposite the second slot 36 of the plate 24. More particularly, the roller 30 is secured to the plate 24 via fixing means 64 allowing the rotation of the roller 30 around a transverse rotation axis R T.

[0074] According to the example of the invention illustrated, the fixing means 64 may comprise the fixing tabs 60 mentioned above and which each comprise a circular opening 66 configured to receive the axis of rotation R of the roller 30, not visible.

[0075] The axis of rotation R of the roller 30 may be, for example, a shaft passing through the roller and housed in the circular openings of the fixing lugs or may take the form of two cylindrical lugs which extend projecting from the transverse free ends of the roller so as to house in the circular openings.

[0076] It is also understood that the roller 30 and the scraping member 32 extend on the same side of the plate 24, here the first side 26.

[0077] The roller 30 as seen in Figure 4, has the shape of double cones of revolution 68 whose bases 70 are in full contact with each other.

[0078] In other words, the roller 30 has a cylindrical shape whose diameter D decreases from a center C of the cylinder, taken in a longitudinal plane L and vertical plane V and formed by the bases 70 of the two cones of revolution 68, towards the transverse free ends 72 of said roller 30.

[0079] In other words, the center C of the roller 30 is defined in a vertical plane V and longitudinal plane L, taken equidistant from the free transverse ends 72 of the roller 30.

[0080] The center C then represents the part of the roller 30 whose diameter D is the largest and the transverse free ends 72 represent the parts of the roller 30 whose diameter D is the smallest.

[0081] According to a non-limiting characteristic of the invention, the roller 30 has a degree of inclination I between its center C and its transverse free ends 72, between 1° and 5°. According to an advantageous example, the degree of inclination I is 2°.

[0082] Such a configuration of the roller 30 is advantageous in that it allows, when using the application device 18, the excess coating to be directed towards the outer periphery of the strip so that it can subsequently be scraped off by the scraping member 32.

[0083] As seen in Figures 3 and 4, the roller 30 comprises a linear contact zone LIN intended to come into contact at least against the strip.

[0084] Thus, at least the linear contact zone LIN located at the center C of the roller 30 and the transverse end edge 50 extend in a common longitudinal plane L and transverse plane T.

[0085] Such a characteristic makes it possible to guarantee contact between the strip and, on the one hand, the roller 30 and, on the other hand, the transverse end edge 50 of the application device 18.

[0086] According to an example of the invention visible in Figure 4, a second transverse dimension DT2 of the roller 30 is defined, taken along its axis of rotation R. The first transverse dimension DT1 of the transverse end edge 50 of the blade 46 is then greater than the second transverse dimension DT2 of the roller 30.

[0087] It is understood that such a characteristic allows the transverse end edge 50 of the blade 46 to ensure optimal recovery of the coating expelled from the periphery of the strip by the roller 30 prior to the passage of the blade 46.

[0088] According to a non-limiting example of the invention, the second transverse dimension DT2 of the roller 30 is between 85mm and 95mm. According to an advantageous example, the second transverse dimension DT2 is equal to 90mm.

[0089] As seen in Figure 4, the blade 46 of the scraping member 32 has a transverse dimension increasing from its fixing edge towards its transverse end edge 50. It is then understood that the blade 46 has a flared shape from its fixing edge towards its transverse end edge 50.

[0090] Such a characteristic makes it possible to maintain an optimal dimension of the transverse end edge 50 of the blade 46 as described above, while limiting a transverse dimension of the tongue 40, and thus of the first light 34. This guarantees optimal scraping of the coating and optimal solidity of the plate 24. The application device 18 visible in FIG. 5 is furthermore configured to cooperate with an assembly comprising a handle 76 coupled to a plate 74. It is thus understood that the plate 74 and the handle 76 form a single piece.

[0091] More precisely, the plate 74 is arranged mainly on the center of the plate 24, straddling the first part 38 and the second part 52 of the plate 24, and extends on the second side 28 so as to at least partially cover the first light 34 of the plate 24.

[0092] The plate 74 is then secured to the plate 24 by a fixing system composed of two screws with nuts, for example of the butterfly type. It is then understood that holes are formed in the plate 24 in order to receive the screws and nuts of the fixing system of the plate 74. Thus, the securing of the plate 74 on the plate 24 is carried out by cooperation of said plate 74 with the fixing system comprising the two screws with nuts. The cooperation between the plate and the fixing system corresponds for example to a snap-fastening of the plate on the latter. Preferably the holes on the plate are spaced 110 mm apart in the transverse direction T.

[0093] Such an assembly comprising the handle 76 and the plate 74 called “finishing box handle” is also known from the state of the art and corresponds to a standard fixing element on the market.

[0094] Advantage is then taken of such a characteristic in that it allows the application device 18 to be used in one direction or the other. Such an advantage of the invention will be explained in more detail during the description of the method of using the application assembly.

[0095] The plate 24 according to the example of the invention illustrated further comprises a front cutout 77 which extends transversely in the first part 38 of the plate 24 and more particularly along a transverse end edge of the plate 24. Such a front cutout 77 is in particular centered on the plate 24 in the transverse direction T.

[0096] Thus, such a front cutout 77 forms a guide means for a user of the application assembly making it easier to move the application device 18 along the strip.

[0097] The front cutout 77 also has a transverse dimension of between 40mm and 60mm. Preferably, the front cutout 71 extends over a transverse dimension of 50mm, usually corresponding to a transverse dimension, or width, of the strip.

[0098] The application assembly 10 also includes the support 20 mentioned above.

[0099] In the remainder of the description, it will be understood that the longitudinal L, transverse T and vertical V directions of the support 20 correspond to those of the application device 18 when the support 20 is used with the application device 18.

[0100] The support 20, particularly visible in FIG. 6, comprises at least one guide surface 78 configured to receive and guide the roller of the application device in rotation, and comprises a scraping wall 80 configured to receive the blade of the scraping member when the roller is guided by the guide surface.

[0101] More particularly, a central portion 82 of the support 20 is defined, the guide surface 78 extending longitudinally from the central portion 82 to a free edge 84 of the guide surface 78.

[0102] The guide surface 78 extends over a third transverse distance DT3 which is greater than the second transverse dimension DT2 of the roller 30 mentioned previously.

[0103] More particularly, the guide surface 78 has a flared shape such that its third transverse distance DT3 is greater at the level of the central portion 82 relative to its free edge 84.

[0104] Such a feature then makes it easier to position the roller on the guide surface 78 at the central portion 82, when using the support 20.

[0105] The guide surface 78 of the support 20 further comprises raised edges 86 which extend in the longitudinal direction L and on the transverse periphery T thereof. Such raised edges 86 participate in guiding and transversely holding the roller along the guide surface 78.

[0106] The raised edges 86 of the guide surface 78 may be formed, in a non-limiting manner, by folding the material of the support 20.

[0107] As seen in Figures 6 and 7, the free edge 84 of the guide surface 78 comprises at least one holding element 88 of the support 20 on the reservoir 22. The holding element 88 may for example be formed by curved tabs 90 so as to form support surfaces which extend in transverse planes T and vertical planes V.

[0108] At least two curved legs 90 then extend offset from one another in the longitudinal direction L, so as to allow the housing of a rim of the reservoir 22 between them.

[0109] In other words, the longitudinal offset of the two curved legs 90 allows the support to engage on either side of the edge of the reservoir 22 so as to radially lock the support 20 in position on said reservoir 22.

[0110] According to the example of the invention illustrated, the support 20 comprises three curved legs 90, one of which is transversely centrally curved legs 90, and is offset longitudinally relative to the other two curved legs 90.

[0111] According to a non-limiting example of the invention, the curved legs 90 are formed by cutting and folding the material of the support 20.

[0112] The scraping wall 80 of the support 20 extends from the central part 82 of the support 20 mentioned previously, and in such a way that it extends opposite the guide surface 78. In other words, the guide surface 78 and the scraping wall 80 are aligned along a first straight line D1 which is parallel to the longitudinal direction L.

[0113] The scraping wall 80 then appears as a wall which projects from the central part 82 of the support 20 in a vertical plane V and transverse plane T and which has a complementarity of shape and transverse dimension with the scraping member.

[0114] It is understood that such a feature allows the scraping wall 80 to be positioned optimally so that the blade of the scraping member licks a free end edge of the scraping wall 80, when the roller is guided in rotation on the guide surface 78, as illustrated in FIG. 7.

[0115] Such scraping then makes it possible to rid the blade of the coating collected when the application device passes against the strip.

[0116] According to an example of the invention, the scraping wall 80 may comprise fixing openings 92 allowing the fixing of a rubber slide, not visible, fixed by a plywood, not visible, by a screwing or riveting method.

[0117] The support 20 further comprises fixing ears 94 for the tank 22. The fixing ears 94 extend in particular on either side of the central part 82 of the support 20 and in such a way that they are aligned along a second straight line D2 perpendicular to the first straight line D1. It is then understood that the fixing ears 94 extend in the transverse direction T.

[0118] The fixing ears 94 then comprise fixing holes 96 allowing brackets, not shown, to be fixed to them for fixing to the tank 22.

[0119] According to the example of the invention, the fixing holes 96 are oblong in shape in the transverse direction T in order to allow the position of the brackets to be adjusted in the transverse direction T.

[0120] The support 20 can thus adapt to different diameters of tank 22.

[0121] According to an advantageous example of the invention, the fixing ears 94 each extend over a transverse dimension of between 25cm and 30cm.

[0122] The fixing ears 94 may each comprise at least one peripheral reinforcing edge 98, formed by deformation of the material of the support 20, in order to improve the strength of the fixing ears 94.

[0123] The method of using the application assembly 10 of the strip 12 according to an example of the invention will now be described in more detail by means of FIGS. 1 to 7.

[0124] The method comprises a first step, called the step of bonding the strip 12, during which the coating is placed to cover at least the joint 14.

[0125] Subsequently, the strip 12 is placed covering the joint 14 and in such a way that it is substantially centered on the joint 14. It is then understood that the strip 12 is held on the joint 14 by means of the coating.

[0126] The method then comprises a second step, during which the strip 12 is tightened, the excess coating is removed and the surface is smoothed. During this second step, the application assembly 10 is used as described above.

[0127] Indeed, the application assembly 10 of the strip 12 advantageously makes it possible to carry out the operations of the second step in a single pass over the strip 12.

[0128] Thus, the application device 18 is installed on the strip 12 by means of the handle 76 fixed to the latter and a translational movement is carried out along the strip 12 while applying constant pressure.

[0129] More particularly, the application device 18 is moved along the strip 12 so that the roller 30 passes before the scraping member 32, on the strip 12.

[0130] In this way, the roller 30 presses the strip 12 against the joint 14 and its particular inverted double cone shape makes it possible to direct the excess coating to the periphery of the strip 12.

[0131] Once the roller 30 has passed over the strip 12, the scraping member 32 recovers the excess coating directed to the periphery of the strip 12 by the roller 30. In other words, the transverse end edge 50 and the wings 54 of the blade 46 of the scraping member 32 allow on the one hand to recover the coating and on the other hand to smooth the surface of the strip 12 on the panels 16 covering the joint 14.

[0132] It is further understood that the handle 76 secured to the application device 18, as described previously, advantageously allows an operator to use the application device 18 without needing a lifting device such as a stepladder.

[0133] The handle 76, and in particular the assembly comprising the handle 76 and the plate 74, called the “finishing box handle”, held by screwing onto the plate 24, also makes it possible to use the application device 18 in two directions, namely from top to bottom or from bottom to top, these directions being defined relative to the earth's surface representing the bottom and according to the earth's gravity.

[0134] Once the application device 18 has passed over the strip 12, the method comprises a third step during which the coating is removed from the application device 18. Thus, during this third step, visible in FIG. 7, the application device 18 is arranged on the support 20 in such a way that the roller 30 is in contact with the central part 82 and the fixing edge 48 of the blade 46 of the scraping member 32 is opposite the scraping wall 80. The application device 18 is subsequently moved in longitudinal translation on the support 20 in such a way that the roller 30 is guided by the guide surface 78 as described previously and in such a way that the blade 46 slides along the scraping wall 80 from its fixing end towards its transverse end edge, thus freeing it of the collected coating.

[0135] The collected coating then flows into the reservoir 22 above which the support 20 is arranged.

[0136] Thus, the application assembly as just described is advantageous in that it makes it easier to apply a strip to a joint between two panels constituting a wall by simultaneously performing the step of tightening the strip, the step of removing excess plaster and the step of smoothing the strip. The application device thus reduces the steps required for applying the strip for an operator and makes it possible to efficiently apply the strip to the entire joint regardless of the height of the wall, in particular by means of the handle fixing element.
