Description

brush

The invention relates to a brush.

The biggest problem with making paintbrushes is fixing the bristles. In this case, on the one hand, a sufficiently high number of bristles must be able to be fastened in order to obtain the desired density of the bristle pack formed from the bristles. On the other hand, it must be ensured that the bristles are reliably fixed so that they do not fall out during use.

One method of attachment consists of inserting the bristles in a tight package into a tube and bonding the ends of the bristles arranged in the sleeve together, for example by means of synthetic resin. Subsequently, the handle of the brush is connected to the sleeve. In this type of attachment, although a very dense bristle package can be obtained. However, the individual bristles are not kept very reliable. Another type of attachment is to fix the bristles by means of small brackets in holes, for example in a wooden body. Although it is in principle possible with this type of attachment to fasten the bristles comparatively well. However, the holes used to receive the bristles need to be a relatively large distance apart, otherwise the body containing the holes will not have sufficient strength to hold the staples. The necessary distance of the holes from each other causes the bristle package is not very dense. This problem is even more serious when used as bristles natural bristles, such as pig hair. While in synthetic bristles, for example, the staple can be placed in the middle of the U-shaped bristles and both ends of the bristle can be used, only one end can be used with pig hair bristles, namely the opposite end of the hair root. It follows that the bristles must be made longer than the actual bristle package, since the lying inside the brush end portion is bent to be able to be attached by the clip can. This is in terms of cost disadvantageous because natural bristles are particularly expensive. In addition, there is a very low density of the bristle package.

The object of the invention is to provide a brush which is characterized by low production costs, a dense bristle package and a reliable fastening of the individual bristles.

To achieve this object, a brush is provided according to the invention with a handle, a bristle carrier plate which is attached directly to the handle, and a plurality of bristle bundles, which are inserted through receiving openings in the bristle carrier plate. This embodiment leads to several advantages. First, the entire bristle package is divided into several smaller bristle bundles, which facilitates the attachment of the bristles. On the other hand, can be dispensed with due to the penetration of the bristle bundles through the receiving openings on brackets, whereby the receiving openings can be made comparatively large. This results in a dense bristle package. It is preferably provided that the bristle carrier plate is a grid. One

Lattice is characterized by the fact that the proportion of the receiving openings in relation to the total area is very large, in particular greater than 50 percent. In this way, a particularly high density of the bristle package results.

According to one embodiment, the handle is provided with a receptacle into which the bristle carrier plate is inserted. This leads to a particularly stable connection between the bristle carrier plate and the handle and also to an attractive appearance. In addition, the receptacle can be made so deep that the edges of the receptacle support the bristle package.

According to an alternative embodiment, it is provided that the bristle carrier plate is provided on its side facing the handle with a circumferential collar. This makes it possible to use the handle in the collar, which can be mechanically stable connected to the bristle carrier plate with little effort. The handle can be glued to the bristle carrier plate or mechanically attached to it, for example by nails, a snap connection, a screw connection, a welded joint, etc. Another advantage of the circulating collar is that a clean finish of the area is given in which the bristle bundles with the boron tenträgerplatte be connected and the handle is connected to the bristle carrier plate.

Alternatively, the handle can also be molded onto the bristle carrier plate, ie encompassing outside within the federal government or else the bristle carrier plate. According to one embodiment, it is provided that the bristle carrier plate is enclosed in a sleeve, which also causes the connection with the stem. The sleeve assumes the function of the federal government. The advantage of this embodiment is that the bristle carrier plate is better accessible for the insertion of the bristle bundles. The sleeve can be made of sheet metal, so that the brush visually looks very similar to a traditional brush.

Preferably, it is provided that the bristle carrier plate on their the

Bristles facing side is provided with a circumferential collar. This supports the bristle package, so that the bristles are held together well.

The collar can have either parallel walls or walls that run away from each other from the bristle carrier plate.

Depending on the intended use, the bristle carrier plate may be flat or arched. This is particularly advantageous in terms of stiffness.

The density of the bristle pack can also be influenced by how the bristle bundles are arranged in the bristle carrier plate. For example, at least one of the bristle bundles can be arranged in a direction that is not perpendicular to the bristle carrier plate. For example, the outer rows of bristle bundles may be inclined to the center of the bristle pack. Thus, a higher density of the bristles can be obtained in the areas in which this is advantageous, or it can be an improved capillary action of the

Bristles are obtained.

The density of the bristle pack can also be varied by the fact that the surface portions of the receiving openings differ from one another in different sections of the bristle carrier plate. By using, for example, smaller receiving openings in the outer area, which are surrounded by correspondingly wider webs, a lower density can be achieved in the outer area of a bristle pack than in the middle, where, for example larger receiving openings can be used, which are surrounded by thinner webs. In this way, even at suitable locations at the base of the bristle package, ie in the vicinity of the bristle carrier plate, small voids can be formed which serve as a "storage space" for color evenly the color reaches the bristle tips when brushing.

The bristles of a bundle of bristles are preferably connected to one another at their ends inserted through the receiving openings. This ensures that no bristles are released from a bundle of bristles.

The inserted through the receiving openings ends of the bristles of a bristle bundle, for example, be welded together. This is particularly advantageous when bristles made of a plastic material are used. For example, the ends of the bristles may be pressed against a heated die so that they melt and weld together. At the same time, if desired, the appropriate side of the bristle carrier plate can be melted by suitable design of the melt die and suitable selection of the pressure, so that the ends of the bristle bundles are also welded to the bristle carrier plate. Optionally, after fusing the bristles with a second punch, they may be forced into the molten bristles to process the surface or to obtain a better density.

Alternatively, it can be provided that the bristles of a bristle bundle are glued together at their ends inserted through the receiving openings, for example by means of a synthetic resin. This is particularly advantageous when bristles are used of a material that is not suitable for welding. By means of the adhesive, the bristle bundles can also be connected to the bristle carrier plate at the same time.

In order to adapt the brush optimally to the respective intended use, it can be provided that the bristle carrier plate is equipped with different bristles. An example of such an assembly is to equip the receiving openings arranged on the outside of the bristle carrier plate with particularly wear-resistant bristles and to fix them in the center of the bristle. Carrier plate arranged receiving openings to stock with particularly color-receptive bristles.

It is also possible to arrange different bristles within a receiving opening, for example a mix of synthetic bristles and natural bristles.

The invention will be described below with reference to various embodiments, which are illustrated in the accompanying drawings. In these show:

FIGS. 1 and 2 show a brush according to a first embodiment. The essential components of this brush are a handle 10, a bristle carrier plate 20 and a bristle package 30th

The bristle carrier plate 20 (see Figure 2) has a grid-like body 22 in which a plurality of receiving openings 24 are formed, which are separated by webs 26 from each other. The receiving openings 24 serve to receive bristle bundles 32, from which the bristle pack 30 is composed. The shape of the receiving openings 24 is essentially determined by the desired properties of the brush and by strength requirements. However, the greater the area fraction of the receiving openings 24 on the total area of the body 22, the higher the density of the bristle pack 30. However, the strength of the bristle carrier plate also decreases since the bars 26 must be made correspondingly thinner. The shape of the receiving openings 24 depends essentially on how the bristles and the bristle bundles 32 formed by the receiving openings 24 are to be arranged within the bristle pack 30.

The webs 26 around the receiving openings 24 may be provided with bevels on both sides, in order to facilitate the insertion of the bristle bundles 32 into the receiving openings 24, and second Bonding of the inserted through the bristle carrier plate 20 ends of the bristles with the bristle carrier plate to improve. The webs are also generated at the base of the bristle package empty spaces, which act as storage space for color. By suitable arrangement and dimensioning of these voids, it is specified how much color can be made available there, how many bristles are in contact with the paint, and how quickly and uniformly the paint is guided from there to the bristle tips during brushing.

The grid-like body 22 is provided on its outside with a collar 28 (see also Figure 1), which serves to receive the handle 10. On the other side of the grid-like body 22, a second collar 29 is provided which surrounds the bristle pack 30 and serves to support the bristles. The collar 29 is here designed so that its walls converge away from the bristle carrier plate. In this way, the bristles are particularly well held together and supported. The bristle bundles 32 are pushed through the receiving openings 24 with the ends that are to be anchored in the brush. Subsequently, the inserted through the grid-like body 22 ends are connected together. In the first embodiment, for this purpose, the ends of the bristles were welded together, so that the mushroom-shaped welding heads 34 shown in FIG. 1 are formed. Alternatively, the ends of the bristles may be melted into a common continuous film-like plastic mass. The film-like plastic mass may be uniformly thick or have different thicknesses over its surface. For example, a thickening of the film-like plastic compound can be formed at the locations where bristle bundles are located. At the same time, the ends of the bundles of bristles 32 can be welded to the bristle carrier plate 20, more precisely with the webs surrounding the receiving openings 24. For this purpose, the bristle carrier plate 20 is preferably made of a plastic which can be welded to the material of the bristles. The handle 10 is inserted into the collar 28 and there with this by means of a

Layer of adhesive 12 connected. As the adhesive, for example, a synthetic resin can be used. The collar 28 has the advantage that on the one hand it receives the handle 10 precisely, so that a mechanically stable attachment is achieved. will create. On the other hand, the collar 28 ensures that no adhesive 12 and also no material of the ends of the bundles of bristles 32 welded together can escape to the outside. So it is a visually very clean connection between the handle 10 and the bristle carrier plate 20 guaranteed. Instead of by means of the adhesive 12, the handle can be connected in other ways with the bristle carrier plate 20, for example by a Rastoder clip connection, by nails, screws or by a thread. It is also possible to carry out the handle 10, for example made of plastic, and to inject it directly into the bristle carrier plate 20, so that it is fastened there. FIGS. 3 and 4 show a brush according to a second embodiment. For the components known from the first embodiment, the same reference numerals are used, and reference is made to the above explanations in this respect.

Generally speaking, the difference between the first and second embodiments is that in the second embodiment, not the

Handle is inserted into the bristle carrier plate, but the bristle carrier plate 20 in the handle 10. For this purpose, the handle is provided with a receptacle 14 which is designed in the manner of a large blind hole. Into the receptacle 14, the bristle carrier plate 20 equipped with the bristles is inserted (see the case P in FIG. 4). The receptacle 14 is designed so deep that the free edge of the receptacle 14 forming apron surrounds the bristle pack 30 similar and supports as the collar 29 in the first embodiment.

The bristle carrier plate 20 is formed in the second embodiment without a collar. It is only on the side on which the ends of the bristles are connected to the bristle carrier plate 20, a small collar 21 is provided which prevents a used for fixing the bristle bundle 32 adhesive 12 flows laterally from the bristle carrier plate 20. The collar 21 furthermore ensures a higher mechanical stability of the bristle carrier plate 20.

For fastening the bristle carrier plate 20 fitted with the bristles inside the receptacle 14, either an adhesive 12 can be used, as shown in FIG. 3, or any other type of fastening can be used. Another difference from the first embodiment is that the collar surrounding the bristles is designed with parallel walls. This makes it possible to produce the federal government with little effort by injection molding.

A third embodiment is shown in FIGS. For the components known from the preceding embodiments, the same reference numerals are used, and reference is made to the above explanations in this respect.

The essential difference between the first and third embodiments is that in the third embodiment, the area ratio of the receiving openings 24 for the bristle bundles 32 is smaller than in the first embodiment. This results in a lower density of the bristle package 30. In addition, it can be seen that the surface portion of the receiving openings 24 in an outer annular region of the grid-like body 22 is greater than in the middle. FIGS. 8 and 9 show a bristle pack 30 with bristle carrier plate 20 for a brush according to a fourth embodiment. For the components known from the preceding embodiments, the same reference numerals are used, and reference is made to the above explanations in this respect.

Various variants of the bristle carrier plate 20 are shown in FIG. 10, which differ in terms of differently shaped receiving openings 24 and different webs between the receiving openings. In addition to the resulting different density of the bristle pack of the respective brush, paint spaces are created by the lands at the base of the bristle pack. In the variant of Figure 10a, an approximately annular rectangular storage space is formed, while in the variant of Figure 10b a central storage space is formed, which is provided with eight "bay windows." In the variant of Figure 10c, a general one is similar to Figure 10a The essential difference between the first and the fourth embodiment is that the bristle carrier plate 20 is rectangular in the fourth embodiment Bristle bundles 32 used, as can be seen in Figure 9 based on the shape and the arrangement of the welded ends of the bristle bundles.

FIG. 11 shows a brush according to a fifth embodiment. For the components known from the preceding embodiments, the same reference numerals are used, and reference is made to the above explanations in this respect.

The essential difference from, for example, the first embodiment is that in the fifth embodiment, the handle 10 is hollow and composed of two shells 40, 42. Integral with the handle 10, the collar 29 is executed, which supports the bristle pack 30 and holds together. For this purpose, the federal government converges conically towards the front. The bristle carrier plate 20 is received in the handle by means of a circumferential groove 44 (see FIG. 12), which is formed in the two shells 40, 42.

The bristle carrier plate 20 can simply be held mechanically in the groove 44. Alternatively, the bristle carrier plate 20 can be glued or welded.

The hollow handle according to the fifth embodiment results in a brush with very low weight. In addition, the two shells 40, 42 can be very easily produced in an injection mold, since each shell can be easily removed from the mold; the mold parting plane runs through the middle of the handle. Also, this can be

Embodiment of the collar 29 are easily tapered running,

FIG. 13 shows a first variant of the fifth embodiment. The difference with the brush shown in Figure 11 is that the handle is reinforced inside by three ribs 46 so that it can not be compressed even if a small wall thickness is used.

FIG. 14 shows a second variant of the fifth embodiment. The difference to the brush shown in Figure 11 is that in the region of the transition from the collar 29 to the handle 10, a closure plate 48 is arranged. This serves on the one hand as a support for the bristle carrier plate 20 and prevents the bristle carrier plate 20 from being pressed into the handle 10 by an excessively strong pressure on the bristle bundle 30. The end plate 48 serves as a separation between the region of the Bristle bundle 30 and the handle 10 and prevents color can get into the interior of the hollow handle 10.

FIG. 15 shows a third variant of the fifth embodiment. The difference to the brush shown in Figure 11 is that the two shells 40, 42 are designed as a multi-component part. In the example shown, in the grip area on the two shells 40, 42, two sections 50 of a plastic are injected, which is softer than the material of the two shells 40, 42, for example of thermoplastic elastomer. Such a softer plastic material improves the feel of the handle and can be suitably arranged as required, for example as a support for the user's thumb and / or forefinger.

According to a further, not shown variant can be provided that the collar 29 is molded from a resilient material to the two shells 40, 42, which form the handle 10. In this way, a yielding within certain limits support for the bristle package 30 is obtained. It is also possible to inject the collar only partially from the compliant material, while other parts are made of the same, harder material as the handle 10.

For the sake of completeness, it is pointed out that the features of FIGS. 13 to 15 can be combined with one another in any desired manner.

In Figure 16, the two shells 40, 42 are shown in section. In the embodiment shown, it can be seen that each shell 40, 42 is provided on a longitudinal edge with a small circumferential welding edge 52, which is opposite to a flat edge of the other shell. This makes it possible to connect the two shells by ultrasonic welding together. It is particularly advantageous that the two shells 40, 42 are made identical, so that one and the same injection mold for producing both shells 40, 42 can be used. Alternatively, the welding edge 52 could also be provided on only one of the two shells 40, 42. It is also possible, the two shells 40, 42 in other ways than by

To connect welding together. Thus, the two shells 40, 42 glued together or mechanically clipped, by injection molding mit- be joined together (for example, by encapsulation with a second material component).

In all embodiments, different materials may be used for the bristles. In particular, plastic bristles may be used, as well as natural fibers such as pig hair, cattle hair, badger, etc. Bristles of plastic may use solid bristles or hollow bristles. The cross-sectional shape of the bristles can be adapted to the respective requirements, for example, be round, star-shaped, triangular, rectangular, or even a mixture of different cross-sectional shapes. Within a receiving opening and different bristle materials can be combined, for example, bristles made of plastic with natural bristles. The tips of the bristles may be preprocessed, for example, rounded or chamfered.

Notwithstanding the embodiments shown, the thickness of the lattice-shaped body can be varied, so that, for example, a greater thickness is provided in regions subject to greater mechanical stress.

A particular advantage resulting from the use of the bristle carrier plate 20 with receiving openings 24, is that the shape of the bristle package 30 can be produced in the desired manner with little effort by simply more or less pushed the bristles into the receiving openings 24 , It is also possible to use from the outset bristles of different lengths, so that the waste is minimized, resulting in lower production costs.

The bristle carrier plate may be provided with elements such as fingers, fins, etc., which may be made of a compliant material, such as thermoplastic elastomer. These elements can support the bristles within the bristle package. With such elements also special coating effects can be brought about, for example structural effects. On the bristle carrier plate, it is also possible to provide elements such as sponges, etc., between the bristle packs, which form an ink supply and influence the color absorption or distribution.
