    专利说明:

    [0001] The present invention relates to a tool to be coated. Over the last ten years, building techniques have evolved and coating operations are now done using prepared plaster that arrives on sites packed in buckets. These new coatings have a certain liquidity that allows them to be applied, for example, to the paint roller or the pump. It is known to smooth the coating deposited with a roll with a coating knife traditionally comprising a blade secured to a box or a handle for the grip of the tool by a user.
    [0002] However, the possibilities of adjusting the inclination of the handle relative to the blade of the tool are often limited to a predetermined number of positions. Also the present invention aims to overcome this disadvantage by providing a coating tool with an infinity of angular settings 15 possible one or more handles on the tool to be coated. For this purpose, the subject of the present invention is a tool to be coated, characterized in that it comprises a longitudinal smoothing element designed to spread and smooth a coating, and a support to which the longitudinal smoothing element is fixed, the support comprising an attachment portion adapted to allow attachment to the support of a handle, the handle comprising two jaws for clamping the attachment portion, and jaw moving means adapted to move the jaws toward or away from one another; another, wherein the fastening portion has a circular section in a plane substantially orthogonal to the length of the longitudinal smoothing member. Thus, the tool to be coated according to the invention has a fixing portion of the handle with a circular section allowing adjustment of the inclination of the handle in an infinite number of positions. This infinity of possible settings is particularly advantageous for working in multiple work positions and at different heights, on a site for example. The tool according to the invention makes it possible in particular to work on vertical walls or ceilings of different heights. Preferably, the support comprises a front concavity and / or a rear concavity delimiting a zone of lesser thickness connecting the fixing portion and the sole.
    [0003] This feature has the advantage of increasing the range of possible angle values for adjusting the inclination between the handle and the tool. Advantageously, the tool comprises the handle and the handle 5 comprises means for connecting to a pole. This allows the assembly of a pole to the handle for use of the tool in inaccessible high areas. According to another characteristic of the tool to be coated according to the invention, the tool comprises the handle, and the jaws have a surface of shape 10 complementary to that of the fixing portion. According to another characteristic of the tool to be coated according to the invention, the surface comprises ridges and in that the fixing portion comprises a rubberized coating. Thus, the adhesion between the jaws and the attachment portion is enhanced. According to one embodiment, the jaws are located at the ends of a split end with two branches, and the jaw moving means comprise an eccentric lever pivotally mounted on one of the limbs and a translational member connected to the lever. eccentric on one side and to the other branch on the other hand. Thus, the rotation of the lever causes the displacement of the translation member. This displacement can cause the bending of the branches, so the approximation of their ends, that is to say the jaws. According to another characteristic of the tool to be coated according to the invention, the support comprises a sole under which the longitudinal smoothing element extends, the sole comprising a front support edge intended to bear against a part intermediate of the longitudinal smoothing element. Thus, the support edge provides a bearing area to bend the longitudinal smoothing member and flatten the plaster, the plaster 30 being crushed instead of being raked. According to yet another characteristic of the tool to be coated according to the invention, the sole comprises means for fixing a rear longitudinal edge of the longitudinal smoothing element, the fixing means comprising a housing for receiving the longitudinal edge. rear of the longitudinal smoothing element, the housing comprising a detent, a guide wall leading to the detent, and a non-return wall, and the fastening means comprise a detent member to the longitudinal smoothing element and intended to bear against the non-return wall. According to an advantageous embodiment, the support comprises means for fastening the longitudinal smoothing element, the fixing means comprising a groove-shaped housing having a return engaged inside a groove of complementary shape, an end of the groove formed by the housing defining an opening allowing the removal or placement of the longitudinal smoothing element by translation of said longitudinal smoothing element substantially parallel to the return. This allows secure attachment of the longitudinal smoothing element on the support while providing a possibility of interchangeability of the longitudinal smoothing element fast to implement. Advantageously, the longitudinal smoothing element comprises two beveled transverse edges. This characteristic has the advantage of limiting the formation of burrs when using the tool according to the invention. According to a characteristic of the tool to be coated according to the invention, the handle is removable. Thus, it can be detached from the rest of the tool to be fixed on a support comprising a different longitudinal element of smoothing. According to one embodiment, the fixing portion is cylindrical. These and other features of the present invention, as well as their advantages, will become apparent from the following detailed description of an embodiment of the present invention, given by way of non-limiting example, in which: FIG. 1 is a perspective view of the front of a tool to be coated according to a particular embodiment of the invention; FIG. 2 is a perspective view of the invention; FIG. rear of a tool to be coated according to a particular embodiment of the invention, - Figure 3 is a schematic sectional view along a plane orthogonal to a longitudinal smoothing element of a tool according to an embodiment of the FIG. 4 is a diagrammatic sectional view along a plane orthogonal to a longitudinal smoothing element of a tool according to one embodiment of the invention, jaws clamped, FIG. 5 is a diagrammatic sectional view a plane orthogonal to a longitudinal smoothing element of a tool according to an embodiment of the invention, with loosened jaws, FIG. 6 is a perspective view of a portion of the tool according to an embodiment of FIG. FIG. 7 is a perspective view of a tool according to another embodiment of the invention; FIG. 8 is a sectional and side view of a tool according to the embodiment of FIG. the invention illustrated in Figure 7. Figure 1 shows a tool 1 to be coated, for example a coating knife, according to one embodiment of the invention. The tool 1 is intended to cooperate with a handle 3. It comprises a longitudinal smoothing element 5 which is advantageously flexible, and a support 7 to which is fixed the longitudinal smoothing element 5. It will be noted that several handles 3, two by For example, may be attached to the support 7. This is particularly the case when the tool 1 extends over a relatively long length to smooth a thick coating, this length being for example of the order of 80, 100 or 120 cm . Thus, a user can manipulate tool 1 with both hands. The longitudinal smoothing element 5 is intended to spread and smooth a coating previously affixed to a surface, for example a wall. The longitudinal smoothing element 5 extends mainly in a direction corresponding to its length. It comprises a longitudinal front edge 9 and a rear longitudinal edge 11, which are in the example of Figures 1 and 2 rectilinear and substantially parallel. The rear longitudinal edge 11 may be smaller than the longitudinal front edge 9. The longitudinal smoothing element 5 also has transverse edges 13 connecting the longitudinal front edge 9 and the rear longitudinal edge 11. The transverse edges 13 are advantageously bevelled to better smoothness of the coating. As illustrated in Figures 1 and 2, they may have a rounded shape to avoid edge effects on the coating and the formation of burrs.
    [0004] According to the embodiment of Figures 1 to 6, the longitudinal smoothing element 5 is a metal blade, elastically deformable, for example stainless steel. According to the embodiment of FIGS. 7 and 8, the longitudinal smoothing element 5 is a flexible lip, for example made of rubber or flexible PVC, making it possible to coat or marouflage the fiber integrated in the coating. This lip can be coiled or coextruded with the support 7 to avoid an assembly step during manufacture. As can be seen in FIG. 8, the lip may have a substantially triangular cross-section with a decreasing thickness towards its forward longitudinal edge 9. This allows progressive resistance to deformation in order to obtain a better quality of smoothing the coating. In the embodiment described, the support 7 is an extruded profile, for example bi-material, that is to say of plastic with a rubber coating that can be overmolded. It has here at each end an opening which is advantageously closed by a lateral plug 15. The support 7 here has a substantially longitudinal shape and extends substantially parallel to the length of the longitudinal smoothing element 5. As shown in FIGS. 1 to 5, the support 7 of the longitudinal element of FIG. Smoothing 5 comprises an attachment portion 17. It may also comprise a sole 19. According to the embodiment described, the support 7 comprises a front concavity 21 and a rear concavity 23 which mark the separation between the fixing portion 17 and the sole 19 and define a zone 25 of lesser thickness connecting the fastening portion 17 and the sole 19. The front concavity 21 and the rear concavity 23 extend longitudinally and rectilinearly along the support 7. The fixing portion 17 is intended for fixing the handle or handles 3 on the support 7. It has for this purpose a circular section in a plane substantially orthogonal to the length of the element 5. In the embodiment illustrated in FIGS. 1 to 6, the fastening portion 17 is cylindrical; it corresponds to a cylinder of revolution.
    [0005] The fixing portion 17 may comprise a rubber coating at its connection with the handle 3. As can be seen in FIGS. 1 to 6, the fastening portion 17 is free of adjustment notches.
    [0006] According to the embodiment of Figures 1 to 6, the sole 19 here comprises a bearing surface 27 of the longitudinal smoothing element 5, a front bearing edge 29, a rear bearing edge 30, and Fastening means of the longitudinal smoothing element 5. As shown in FIG. 3, the fastening means of the longitudinal smoothing element 5 can comprise a housing 31 formed under the support 7, intended to receive the rear longitudinal edge. 11 of the longitudinal smoothing element 5, and to cooperate with a flexible detent member 33, for example stamped in the longitudinal smoothing element 5. The housing 31 comprises an advance 35, which extends to 15 under the rear support edge 30 for prestressing the longitudinal smoothing element 5 against the rear support edge 30. The housing 31 also comprises a curved inner guide wall 37, for guiding the rear longitudinal edge 11 to a stop of encliquet when the rear longitudinal edge 11 is inserted into the housing 31. The locking stopper 39 is advantageously positioned below the plane P of the bearing face 27, as illustrated in FIG. to press the longitudinal smoothing element 5 against the bearing face 27. The housing 31 also comprises a non-return wall 41, against which slides and rests the locking member 33 during the insertion of the longitudinal edge rear 11 25 in the housing 31. The inner non-return wall 41 extends from the bearing surface 27; it is advantageously inclined at an angle α less than 90 ° relative to the plane P of the bearing face 27, so that the deployment of the detent member 33 in the housing 31 allows to push the rear longitudinal edge 11 against the detent 39. According to the embodiment of FIGS. 7 and 8, the fastening means of the longitudinal smoothing element 5 comprise a housing 31 which is formed in front of the support 7, that is to say along the front edge 29 of the support 7. The housing 31 is intended to receive the rear longitudinal edge 11 of the longitudinal smoothing element 5. Advantageously, the housing 31 forms a groove having at least a return 66 shaped to retain the longitudinal smoothing element 5 in the groove in case of traction of the longitudinal smoothing element 5 in a direction substantially perpendicular to its length. In addition, the longitudinal smoothing element 5 has at least one groove 67 in which is engaged the return 66. In addition, the ends of the groove 5 forming the housing 31 define openings which can remain unclosed. This allows secure attachment of the longitudinal smoothing element 5 to the support while offering a possibility of rapid interchangeability to be implemented by translation of the longitudinal smoothing element 5 with respect to the support 7, in a direction parallel to the length of the longitudinal smoothing element 5. According to the embodiment of Figures 1 to 6, the front bearing edge 29 of the sole 19 is intended to bear against an intermediate portion of the longitudinal member. 5, that is to say a portion of the longitudinal smoothing element 5 situated between the longitudinal front edge 9 and the rear longitudinal edge 11. The front support edge 29 offers a bearing zone for bending of the longitudinal smoothing element 5. As can be seen in FIG. 3, the distance between the front support edge 29 and the rear support edge 30 is greater than the distance between the front support edge 29 and the longitudinal edge 9 before the longitudinal smoothing element 5, for an amplification of the efforts provided by the user. Thus, the flexing of the longitudinal smoothing element 5 between the front support edge 29 and the rear support edge 30 is, when the longitudinal smoothing element 5 is pressed by a user against the surface on which is affixed the coating, more important, which allows a flat smoothing of the coating, and thus crush the plaster instead of raking. In the embodiment of Figure 1, the front bearing edge 29 is substantially parallel to the front longitudinal edge 9 and here extends rectilinearly. As can be seen for example in FIG. 1, it will be noted that the sole 19 is here substantially longitudinal and extends over the entire length of the rear longitudinal edge 11 of the longitudinal smoothing element 5. The handle 3 comprises one of its ends securing means for reversibly fixing it to the support 7, so that the handle 3 is removable. The removability of the handle 3 allows a change of the longitudinal smoothing element 5, for example to use a longitudinal smoothing element 5 of larger or smaller dimensions.
    [0007] The fixing means comprise a split end piece 43, two jaws 45, and clamping means of the jaws 45, comprising for example an eccentric lever 47 and a translation member 49. The end piece 43 comprises two flexible branches 51. It has a substantially U-shaped shape. The jaws 45 are integral with the ends of the branches 51. They may have a surface 53 of complementary shape to that of the fixing portion 17. In the example of FIGS. 1 to 6, the jaws 45 thus correspond to fragments of cylinders of revolution. Advantageously, the surface 53 of the jaws 45 intended to come into contact with the fixing portion 17 comprises a plurality of grooves intended to increase the friction between the jaws 45 and the fastening portion 17 at least partially coated with rubber. Advantageously, the surfaces 53 of the jaws 45 are diametrically opposed. The lever 47 is pivotally mounted on one of the branches 51, between a clamping position, visible in Figure 4, in which the lever 47 is pressed against the jaw 45 at the end of the branch 51 to which it is attached, and a release position, visible in Figure 5, in which the lever 47 is raised and allows the loosening of the jaws 45. 20 the translation member 49, for example a screw as in the example of Figures 4 and 5, is connected to the lever 47 on the one hand, and the other leg 51 on the other hand, that is to say to the arm 51 opposite to that receiving the lever 45. Thus, the rotation of the lever 47 causes the displacement of the translation member 49, and consequently the approximation or the distance of the jaws 45. The approximation of the jaws 45 allows to grip the fixing portion 17 to secure the handle 3 to the support 7. The removal jaws 45 allows the separation of the handle 3 and the support 7 for example, for a change of the longitudinal smoothing element 5. The handle 3 advantageously comprises a rubber coating for increasing the adhesion between the handle 3 and the grabbing hand of the user. According to the embodiment described, the handle 3 extends in a direction substantially orthogonal to the direction in which the support 7 extends.
    [0008] As shown in FIG. 6, the handle 3 may comprise at another end means for connecting to a pole 55. The connecting means comprise, for example, a male end 57 shaped to cooperate with a socket 59 located at a end of the pole 55. The male end 57 advantageously comprises a clipping member 61 projecting from the male end 57. The clipping member 61 is thus held in position by a return member such as a spring.
    [0009] The female end 59 comprises a hole 63 intended to receive the clipping member 61 to finalize the assembly of the pole 55 and the handle 3. The male end 57 and the female end 59 may comprise means for positioning of one with respect to the other, formed for example by a groove 65 of complementary shape of a rib 67. Of course, the invention is not limited to the embodiment described above; embodiment having been given only as an example. Modifications are possible, especially from the point of view of the constitution of the various elements or by the substitution of technical equivalents, without departing from the scope of the invention. Thus, instead of a cylindrical shape, the fixing portion 17 could have a surface of revolution other than cylindrical. It could then be formed by the association of two truncated cones contiguous to one another.
    [0010] The shape of the fastening portion 17 is not limited to the surfaces of revolution; the fixing portion could also be achieved by the combination of any two cones. Finally, the support 7 could comprise only one of the two concavities among the front concavity 21 and the concavity rear 23. 30
