Description

The present invention relates to a brush for applying

  liquid or pasty products, such as in particular paint, glue or other, on a support. It will find its application in all areas where it is necessary to apply or implement such products on various media, and in particular in the field of building decoration. In this field, it is known to use brushes of various shapes and sizes, depending on the applications, to put paint or glue on the walls, or other supports,

  to be covered by these products.

  Currently, due to the diversity of the surfaces to be covered, the products to be applied, and the complexity of the operations to be carried out, a number is used.

  important brushes of various shapes and sizes.

  This diversity requires the user to have a large range of brushes, which for him represents a

important investment.

  This investment is also increased by the fact that, to avoid a loss of time too important on the site resulting from the cleaning brushes, especially when a change of paint or product to apply, or just when changing the surfaces to be painted, one must generally use several

brushes of the same type.

  Also, the need for this large number of brushes requires an important place to allow storage, both on the site, the level of the workbench of the user. This constraint is also encountered when transporting or selling paintbrushes in

adapted packaging.

  Indeed, not only the head comprising the fibers for the application of the products can be bulky, but whatever the nature and shape of these, each brush currently has a

  sleeve or more generally gripping means.

  Until then, because of the problem of the need for perfect head restraint on the neck, there was a prejudice, commonly shared by those skilled in the art, in this area, suggesting that it was not desirable to make the head and the gripping means removable. Indeed, it is necessary not only that the handle is perfectly maintained in the head to avoid its dissociation during use of the brush, but it is also necessary that this association is perfect to avoid unwanted introduction of the product to be applied to the inside of the head so that there is no possibility of altering the means of association

of these two elements.

  In addition, these means must withstand repeated use, that is to say a successive implementation

  on the same set of separate heads.

  Nevertheless, some attempts in this direction have been imagined, so it is known a paintbrush artist for watercolor whose handle and the ferrule are removable via a piece fitted in the ferrule of a left and screwed on the handle on the other hand. If such an achievement can be considered for watercolor, it is out of the question to extend this structure to industrial brushes given the imperatives.

necessary techniques.

  Also known is a brush having a handle and a removable head, the end of the handle is worked in the form of a bell to receive internally a tuft of fibers, also mounted in a special way

  on a solid ring adapted to said bell.

  Such a brush has not had any significant development, this being inherent to the structure of the means used, which means that finally the handle is always associated with the same tuft of fibers, and makes it lose

all the interest in the system.

  The present invention aims to overcome the disadvantages of currently known brushes by reviewing the entire concept and arriving at a single-handle brush system that is also interesting for

  the user only for the manufacturer.

  In this regard, the present invention provides a brush whose structure has been designed around a single and interchangeable handle adapted to receive a multitude of ferrules whose tuft of fibers is adapted according to the

quality and form required.

  In this regard, according to the present invention, the brush, intended to apply liquid or pasty products, such as in particular paint, comprising gripping means, at least constituted by a handle, and means for applying said products, to less constituted by a ferrule adapted to internally receive a tuft of fibers associated with each other by glue, is characterized in that it has an intermediate head, secured to the ferrule by cooperation with said glue on the one hand, and associable removably handle the other hand, whose profile allows the adaptation of the same handle on a multitude of head-ferrules sets. The advantages of such a structure are twofold since they facilitate the task of the manufacturer and allow the user to organize his entire range of

brushes around a single handle.

  Indeed, at the time of manufacture, the final assembly is made from standardized elements namely: a single handle, a head of unique concept and shape adapted to different ferrules, ferrules

  corresponding tufts and fibers.

  As far as the user is concerned, he will be in the presence of both a single round and a

  number of head-ferrules corresponding to his needs.

  Also, as seen, one of the advantages of the present invention lies in the fact that it allows a reduction in the size mentioned above, which facilitates the transport and presentation of brushes, and their storage as well on the site of use that in the painter's studio or even on

the places of sale.

  Another advantage of the present invention lies in the production of low cost parts, and taking into account the recovery of the handle, the present invention develops the concept of the brush head

disposable.

  Other purposes and advantages of this

  invention will appear during the description that will

  to follow, which is however only indicative and

which is not intended to limit it.

  More precisely, the invention will be well

  understood on reading the following description

  accompanied by the appended drawings among which: FIG. 1 shows a profile view of a brush made according to the present invention; FIGS. 2a to 2c show the different main elements constituting the brush of the present invention illustrated in FIG. FIG. 3 shows a partial sectional view of the elements respectively represented in FIGS. 2b and 2c assembled together; FIG. 4 shows a view of the head and the ferrule, represented in FIG. 3, assembled, according to a first variant, on a handle, - Figure 5 shows a view of the head and the ferrule, shown in Figure 3, assembled, in a second variant, on a handle, - Figure 6 shows a sectional view of a

  The present invention relates to a brush for applying liquid or pasty products, such as in particular glue or paint, on a support. It will find its application in all areas where it is necessary to apply or put in place such

  products on different media.

  In the description that follows, we have more

  particularly illustrated a brush 1 whose handle 2 has a circular section, and whose tuft of

Fiber 3 is also round.

  However, of course, this embodiment is in no way limiting and it is quite possible to produce, from the present invention, brushes whose handle has a polygonal section, and whose fiber bundle also has a cylindrical, conical, polyhedron shape, or any other specific form, adapted for a particular use. Regarding the handle 2, it is made of any type of material, such as for example wood, metal, light alloy, PVC plastic or other material, or composite material. It naturally has a length determined according to the applications as well as a diameter adapted to ensure a perfect maintenance for the user. However, the brush 1 comprises means for applying said liquid or pasty products, at least consisting of a shell 4 adapted to receive internally a bundle of fibers 3 associated with each other

by glue.

  The brush of the present invention, as shown particularly in Figure 2, further has an intermediate head 5, adapted to be secured to the ferrule 4 by cooperation with said glue, this point will be

  described in more detail later.

  In addition, the intermediate head 5 is adapted to be removably associated with the handle 2, and its profile allows the adaptation of the same handle on a multitude

of 5-ferrule head assemblies 4.

  So, the handle 2 can be unique and can

  receive a multitude of intermediate heads.

  The association of the intermediate head 5 and the ferrule 4 is more particularly illustrated in FIG.

3.

  The intermediate head 5 is constituted by a sleeve 6, one of the ends 7 is adapted to the distal end 9 of the handle 2, and the other end 8 is adapted to the upper part.

of the ferrule 4.

  In addition, the sleeve 6 forming the intermediate head has a fastening stud 11, directed on the ferrule side 4, 10, and in particular beyond the lower end 8 of the sleeve, in order to cooperate, as specified above, with said adhesive

  associating the fibers of the tuft 3 with each other.

  As regards the shell 4, it is constituted by an annular body 12 having, at its lower part, a collar 13 for holding the fibers of said tuft 3, and at its upper part 10, a housing 14 intended on the one hand receiving the top of the fibers, not shown in Figure 3 to simplify the sketch, and receiving said glue 15 to associate said fibers of

the tuft 3.

  Regarding the annular body 12, it is for example made of a smooth outer part, made of a metallic or synthetic material, the surface state of which has excellent non-stick properties to facilitate its cleaning, in particular particles of glue or paint, which are likely to

  hang during the use of the brush.

  In addition, as traditionally, the annular collar 13 can be made by means of a string or even by metal fibers of small section to tighten the top of the fibers at the exit of the ferrule, while leaving flexibility to the rest of the the outer tuft. In this regard, the fibers are engaged, at the time of assembly, by the upper part 10 of the ferrule, in the housing 14, to pass inside thereof, until their ends come out of the other side over a determined length in

according to needs.

  Then, glue 15, in particular heat-hardenable, is injected to secure the top of the fibers together on at least a part of their length trapped inside the ferrule such that the

  suggests Figure 3 and show it in Figures 6 and 7.

  However, when mounting the fibers of the tuft 3 in the shell 4, and before the glue 15 is hardened, the intermediate head 5 is placed above the shell 4 to match the respective parts vis-à-vis -vis 8 and 10. Then, the glue filling 15 and the length of the fastening nipple 11 being such that the latter penetrates into the glue which, once taken, will rigidly bond the head 5 and the ferrule 4, the interface 16 of the two elements reinforcing the

  stability and rigidity of the whole.

  As shown in the figures, and in particular in FIGS. 3 to 7, the fastening stud 11 has a grooved end 17 for facilitating its engagement in the glue 15. In one embodiment, the end 17 is made by a succession of rings

  parallel to each other and spaced apart to define grooves.

  As mentioned above, the end 7 of the sleeve 6, that is to say the handle, is in particular cylindrical, and depends on the handle, while the end 8 of the sleeve 6, that is to say ie side ferrule 4, is adapted to it and thus has an opening by

cylindrical or polygonal example.

  Regarding the handle 2, it has at its distal end 9 as shown particularly in Figure 2a, one or grooves 18. In return, the intermediate head 5 has at its end 7 side handle, one or ribs corresponding 19 for

  authorize the locking of the handle 2 on the head 5.

  For the embodiment described so far, FIGS. 4 and 5 show the positioning of the handle 2 on the head 5, the fastening stud 11 of the handle being trapped in the glue 15 provided at the level of FIG.

  from the top of the fibers inside the ferrule.

  That being so, in a first embodiment, said rib or ribs 19 are carried by a split sleeve 20 allowing the elasticity of this

  last for snapping and disengaging.

  However, in another embodiment, not shown in the figures, the handle 2 may have at its distal end 9 a thread, and in this case the intermediate head 5, handle side 7, will have a complementary thread to allow the screwing of the handle on the head. Incidentally, the arrangements that have just been described also make it possible to provide a removable identification ring 21, arranged between the handle 2 and

the intermediate head 5.

  For example, this arrangement is illustrated in FIG. 5 in which the ring 21 is cylindrical and slips around the upper part 22 of the part

distal 9 of the handle.

  Such a ring will in particular make it possible to identify, according to colors, the quality of the fibers, the

destination brush or other.

  In the description that has just been realized,

  the intermediate head 5 is constituted by a one-piece integral sleeve performing the various functions described. However, for purposes of facilitating its implementation, it can be provided in several parts, and in particular the fastening pin 11 can be reported. In this case, the sleeve 6 has at its lower part an insert consisting of a cylindrical piece whose inner dimension is provided to fit the end 8 of the sleeve, this cylindrical piece bearing, along its longitudinal axis, said nipple solidarity 11

directed side ferrule 4, 10.

  However, Figures 6 and 7 show two other embodiments in which the shape and structure of the intermediate head 5 is somewhat different. In this case, the intermediate head, marked 50, and more flattened, but still has a profile allowing the adaptation of a handle on a multitude

of head-shell assemblies.

  In the lower part, there is a fastening pin 51 able to cooperate with the glue solidarisant between it the top of the fibers inside of

the ferrule.

  In Figures 6 and 7, for ease of understanding, we have taken the same references for the handle 2, the shell 4 and the tuft of fibers 3 and

for glue 15.

  However, the distal portion of the handle 2 has a different groove shape 52, hollowed out of the handle as in Figure 6, or reported as the

shows figure 7.

  Under these conditions, the upper part of the head has a cylindrical portion 53 equipped with a ring or snap-in studs 54, able to take place by

  elasticity in said groove 52.

  Of course, other embodiments within the reach of those skilled in the art could have been envisaged

  without leaving the scope of it.
