Definitions
- Adjustable coating knife handle and coating knife provided with such a handle
- the invention relates to an adjustable coating knife handle and a coating knife provided with such a handle.
- Conventional coating knives have a cylindrical handle fixed to a blade substantially perpendicular to the free edge of the blade.
- the handle is grasped "with the full hand", that is to say that the fingers and the thumb are wound in opposition around the handle.
- the blade is applied with force against a surface to apply and smooth the coating.
- the blade should have sufficient flexibility to bend to apply the plaster without scraping it from the face and sufficient rigidity for the plaster to be pressed against the surface.
- An improvement consists in fixing a handle parallel to the blade.
- the coating knife is grasped by pinching the handle between the fingers.
- Mention may be made, for example, of documents FR2327374, DE1 845335 and EP21 37364 which describe such a coating knife.
- This type of handle has the advantage of allowing the manufacture of the handle with a profile which can be cut to the desired length. It is thus possible to manufacture coating knives of great width, which allows faster and more homogeneous work, since the application force is transmitted over the entire width of the blade.
- this type of coating knife is impractical, because all the compressive force to be transmitted to the coating is generated by the pinching of the handle between the fingers of the hand, which makes the operation painful and tiring.
- this document illustrates a position in which the handle is held in the palm of the hand, but this position forces the wrist to bend strongly during the application of the plaster, which induces pain due to use.
- the documents DE 1 845335 and EP21 37364 propose a notable improvement of the coating knife of the previous document, by providing a handle provided with a gripping part and a lever part.
- this type of very rigid handle requires a position of the hand very close to the surface, forcing the user to strongly break the alignment between his hand and his forearm at the level of the wrist.
- the alternative is to provide a very flexible blade, but this is to the detriment of the quality of application of the product.
- this type of handle generates musculoskeletal disorders both in the fingers, but also in the wrist.
- the objective of the present invention is therefore to provide an economical handle, that is to say that can be easily manufactured in the form of a profile, light and which limits the fatigue of use, while ensuring a optimal application of the plaster and great versatility of use.
- the invention provides a gripping portion adjustable in angular position relative to the plane of the blade.
- the invention also provides that the gripping part makes it possible to combine the advantages of a powerful grip of the cylindrical sleeves and of a uniform application of the profile sleeves, while avoiding by hand to tetanize during application.
- the invention more precisely relates to a knife handle to be coated in profile extending along a longitudinal direction, the handle comprising two profiles movable relative to each other in a sliding manner:
- a first gripping profile comprising a portion for fixing an edge of a blade to be coated, connected to a central portion integral with a first gripping portion of a gripping portion forming, seen in cross section, a hook open with an internal surface in an arc of a circle,

- the handle according to the invention makes the application of coating easier, less tiring, and in a manner adapted to the morphology of the user and / or orientation of the coated surface.
- the cusp of the handle according to the invention allows stiffening the user's wrist, which transfers the application effort to the arm and therefore to the shoulder, which is much more resistant to fatigue.
- the means for locking in rotation may comprise complementary reliefs carried by the outer surface of the cylinder of the lever portion and by the inner surface of the engagement portion;
- the rotation locking means may comprise at least two grooves carried by the inner surface of the arc of the engagement portion and a rib carried by the outer surface of the arc of the cylinder of the lever portion;
- the means for locking in rotation may comprise at least two grooves carried by the outer surface of the arc of the lever portion and a rib carried by the inner surface of the arc of the grip portion;
- the two sections can be movable relative to each other in a sliding manner along the longitudinal direction of the sections, and in rotation around the longitudinal direction, the sections being blocked with respect to each other in rotation by means of attached rotation locking;
- the means for locking in rotation may comprise a groove carried by the inner surface of the arc of the engagement portion, at least two grooves carried by the outer surface of the arc of the lever portion, and at least one key integral blocking of the grip portion;
- the circular arcuate inner surface of the gripping portion may be smooth, the rotational locking means comprising at least two grooves carried by the circular arcuate outer surface of the lever portion and at least one integral locking key the portion taken;
- the locking key can be carried by an end cover of the profiles
- the key can be mounted movably between an engagement position in at least one groove carried by the outer surface of the arc of the lever portion, and a disengaged position to allow rotation of the two portions of the gripping portion one in relation to the other; • the key can be mounted fixed on the cover which carries it;

- the insert 96 is placed in the oblong body of the profile .
- the insert is placed in the rear bearing face.
- the insert can be placed at other places on the body, depending on the shape of the profile and the angle that one wishes to give to the handle with respect to the knife to be coated when the handle is screwed into the insert.
- the fixing part 80, 90, 95 of course comprises means for locking in rotation with respect to the gripping profile.
- these locking means comprise two grooves carried by the inner surface in the arc of a circle of the gripping portion and a rib carried by the outer surface in the arc of a circle of the cylinder of the fixing part 80, 90, 95 .
- the gripping profile 10 and the lever profile 20 can also be mounted so as to be able to rotate with respect to one another.
- the two sections are mounted movable relative to each other in a sliding manner along a longitudinal direction of the sections, and in rotation around the longitudinal direction, the sections being blocked. one relative to the other in rotation by an attached part.
- At least two grooves are carried by the outer surface of the arc of the lever portion and a groove is carried by the inner surface of the arc of the grip portion.
- at least two grooves are carried by the outer surface of the arc of the lever portion, the inner surface of the arc of the grip portion being smooth, that is to say devoid of relief (groove or rib).
- each cover carries a fixed key which acts as a locking stop when it is inserted into one or two grooves.
- the covers comprise a key movably mounted between an engagement position in two grooves carried by the two portions of the gripping part in order to block these two portions in rotation with respect to each other, and a release position to allow rotation of the two portions of the gripping part relative to each other.
- the or each key is integral with an actuating lever and with a return means in the engagement position.
- the key in the absence of any action by the user, the key is maintained in the engagement position, and it is only when the user wants to modify the angle of the lever portion that he actuates. the lever (s) for disengaging the key (s) and rotating said lever portion relative to the engagement portion.
- the return means such as a spring.
- the covers comprise a key movably mounted between an engagement position in a groove carried by the lever portion of the gripping part, and a disengaged position to allow rotation of the two portions of the gripping part. one in relation to the other.
- This embodiment with fixed covers makes it possible to prevent disassembly of the blade.
- FIG. 1 8 and 19 Another embodiment with fixed covers preventing disassembly of the blade is illustrated in Figures 1 8 and 19.
- the first gripping profile 10 comprises, on each side, a fixed cover 14 arranged in front of the slot 11 for fixing the blade and thus preventing the dismantling of the blade.
- the cover 14 covers neither the section of the cylinder 21 of the second profile nor the section of the hooked part 1 1 1.
- the cover 14 covers only the section of the fixing portion 130 and of the central portion 120.
- the second lever profile 20 comprises, on each side, a fixed cover 24 which covers only the section of the oblong body 22, but not the section of the cylinder 21.
- the profile 20 also comprises a movable cover 25 covering not only the section of the cylinder 21, but also the section of the hook part 1 1 1 of the first profile.
- the movable cover 25 is fixed to the cylinder 21 of the second section 20 by a threaded fixing wheel which engages in a threaded hole 26 in the cylinder 21.
- lever profile 20 is rotated to place it in the second position of use, as in the embodiment of FIG. 6, and the cover 25 is reattached with the wheel 52 on the cylinder 21.
- This embodiment therefore allows a change in position of the lever profile while preventing the removal of the blade.
- the handle may have stiffening reinforcements inside the profile
- the profile of the handle can be manufactured by extrusion and then cut to the width of the blade to distribute the pressure over the entire width.
- the outer and inner surfaces of the cylinder and of the hook of the gripping part are fully fluted so as to allow a multitude of positions while ensuring friction, and therefore a significant hold between the two profiles.
