Description

Brush manufacturing device, brush body fixture and method for manufacturing brush

The present invention relates to a brush manufacturing apparatus in which a brush body is further processed, the brush body having an opening for receiving and fixing the bristles, and the brush body is a part of the brush to be made.

Further, the present invention relates to a brush body holder applicable to the above brush manufacturing apparatus, and a method of manufacturing a brush.

Brush manufacturing equipment is a high-precision working machine that manufactures and further processes brush parts on several successive workstations. The brush itself has a brush body, and the brush body of the toothbrush comprises a handle, a neck and a head. The head has an opening arranged in a predetermined hole shape, and the bristles are bored to the hole type. These bristle bundles are then fixed to the brush side. A so-called "plug" operation can be performed for the entire brush body or a portion of the brush body (e.g., holding the sheet), which has the necessary openings for the tuft of bristles. This is held in the sheet opening and then connected to the remainder of the brush body. This can be achieved by squeezing or fixing the pre-formed remainder of the brush body. The present invention relates to a brush making apparatus for further processing of a sheet and a finished brush body or a component of the brush body. An open body having bristles for insertion or a brush body that can be inserted into the bristled retaining sheet itself and a retaining sheet or, in general, a prefabricated component that will participate in the definition of the brush body in the future, will hereinafter be referred to as a brush body. The brush manufacturing apparatus of the present invention described below does not limit the manner in which the bristle bundles are fixed to the brush body. It can be fixed by anchor or fixed by anchor.

Further, the present invention relates to a brush manufacturing apparatus which performs one or more of the following steps in the manufacture of bristles: a plug hole for fixing the bristles to the brush body, and processing (trimming, round head processing) the ends of the bristles.

Brush manufacturing equipment must be designed to be extremely flexible, meaning that the brush manufacturing equipment must be able to be quickly modified. Because the number of brushes to be made increases, the cycle also becomes faster. The brush body must be positioned with the highest precision at high speeds. This means that when it is necessary to modify the equipment to accommodate the new brush, the positioning unit must be precisely adjusted at each station.

The key is that the positioning unit for clamping the brush body to the respective processing station is precisely adjusted. However, since the brush body has different outer geometries on the periphery (side edge) of the brush body, the adjustment is difficult.

It has been suggested that the brush body be fed into the brush holder in advance instead of the insertion device to form a unit. In this case, the brush holder has a relatively simple outer contour for the brush making device to be relatively easily caught, so that the centering and positioning operations can be performed quickly. What is important is that several different brush bodies have different accommodating profiles in different brush holders, that is, have individualized accommodating modes. However, the different brush holders have the same contour on the portions where the brush holders are positioned and held in the brush manufacturing apparatus. In this way, despite the different brush bodies, complex positioning unit adjustment operations can be completely eliminated or simplified.

To this end, the envisaged brush holder has an opening that tapers slightly from the front of the brush body toward the back side, relative to the outer geometry of the brush body to be inserted into the openings. The opening size is insufficient. Thereby, the brush body inserted from the front is clamped like a wedge.

It is an object of the present invention to provide a brush manufacturing apparatus, a brush holder, and a manufacturing method which can further simplify and speed up the manufacture of a brush.

The solution to achieve this object of the present invention is a brush manufacturing apparatus in which a brush body is further processed, the brush body having an opening for receiving and fixing the bristles, and the brush body is a brush to be made A portion of the body having a back surface and a front surface, the bristles projecting from the front surface after the brush is formed. The brush manufacturing apparatus includes a brush body clamp, wherein each of the brush body clamps is detachably insertable into at least one brush body to form a form-fitted temporary unit, the unit being fed into the apparatus, through the apparatus and Transport off the device. The brush manufacturing apparatus further includes a device end positioning unit that holds the unit and positions the unit in the apparatus in a manner of chucking the brush body when the brush body is further processed, wherein the brush body clamps It is designed to have a mechanical stop to prevent the corresponding brush body from coming off the brush body clamp from the back side toward the front side.

The present invention is provided with a plurality of brush holders that pass through a brush manufacturing apparatus. That is, it is not a fixture that is permanently installed in the device and becomes part of the device. More specifically, each brush holder is combined with one or more brush bodies to form a unit that passes through stations in the device or a single station. Therefore, the brush holders are temporary movable clamps that correspond to the brush body rather than the device. The brush holders are characterized in that the brush holders are not inserted from the front like the brush holders conventionally conceived, and are fastened to the brush holders only by the clamping method (wedge effect). More specifically, the brush holders have one or several mechanical stops that prevent the brush from falling out. The direction in which the or the stops act may be defined most simply from the back of the brush body toward the front. It should be noted that the brush body clamp has a back surface and a front surface, and the back surface and the front surface respectively correspond to the back surface and the front surface of the brush body accommodated in the brush body clamp, that is, the two orientations are consistent. The mechanical locking effect is obtained by the stop to prevent the brush body from falling forward. This is particularly beneficial when machining a bundle of bristles that have been inserted into the brush body. Because of the need to trim the tufts of bristles or to treat the bristles to the round head, it is possible to create a pulling force that would cause the brush body to disengage from the bristle holder of the brush body.

The positioning unit should only clamp the brush holder so that it can benefit from the same shape of the brush holder, which is not affected by the type of brush body or the external geometry, and does not have to be realigned.

Furthermore, a transport unit can be provided which only catches the brush holder and transports the unit through the device. Thus, the transport unit also benefits from the uniform shape and external geometry of the brush body clamp that is always the same, independent of the geometry of the brush body housed in the brush body clamp.

The transport unit can include movable jaws that laterally engage the brush body clamp and receive the brush holders to move the brush holder toward or away from the positioning unit. That is, the transport unit preferably grips the edge of the brush holder (i.e., the periphery) from the outside, but other implementation variations may be employed therein. For example, the brush holder can also have one or several openings into which the pins of the transport unit can be inserted to take the brush out of the positioning unit and continue to transport it.

The brush holders are configured such that the brush bodies received in the brush holders are gap-free in all directions. That is, even if the brush body is inserted into the brush holder from the back side, when the unit is raised, the brush bodies do not fall from the brush holders.

In order to simplify the manufacture of the brush holder, in particular for the purpose of more conveniently positioning and transporting (ie gripping) the brush holders, the brush holders have at least one for the positioning unit on the side edges of the brush holders and Or) the flat contact surface of the transport unit. More preferably, however, two opposing and parallel flat contact faces and/or openings for the positioning unit and/or the transport unit are provided.

The brush holders may have a plate-like shape and have a receiving opening for the brush body, wherein the receiving opening is defined by a retaining edge that catches a side edge of the brush body. The plate shape is easy to manufacture and is also conveniently positioned securely on the first plane (ie, the placement plane) on each station of the device or device.

The receiving opening may have a shape that is at least partially complementary to the outer circumference of the brush. It is advantageous that the accommodating ports do not have to be completely complementary, and more precisely, only a partial section is provided as a contact surface. This reduces friction and reduces jamming between components. When manufacturing the brush holder, only the contact portion is extremely difficult and requires high precision. Therefore, if the contact surface becomes small, the manufacturing can be simplified.

Embodiments of the present invention provide that the brush holder is designed to form a snap-fit connection with the at least one inserted brush body. This snap connection is particularly advantageous because it combines the quick insertion and removal of the brush body in the brush holder with mechanical latching.

The brush holder or the section of the brush holder may be composed of an elastic material such as plastic or may be made of metal. When the brush body is received, the segments directly press against the brush body and hold the brush body. Therefore, the snap connection is implemented not only to form a shape fit with the brush body, but also to further clamp the brush body.

According to a particularly simple variant, it is proposed to sew the plate-shaped brush body clamp, that is to say to define two relatively movable sections with the gap. The segments can be spaced apart from each other to accommodate the brush holder and then move back and forth to maintain the brush body.

The slit forms, for example, two spaced sides (Schenkel) which are relatively resilient to form a snap-fit connection. The slit may extend to the side edge of the brush holder, meaning that only one side or one end is excluded, the gap being continuously extended. Thus, one side of the two sides is elastically connected and preferably integrally connected through the base (Steg), in which case the base is primarily used to achieve relative mobility of the sides. At the opposite end, the sides form a free end, respectively.

As an alternative to the elastic design of the brush holder or a complementary change that can be combined with this, it is proposed that the slit continuously passes through the brush holder to form a plurality of sections, which may also be separate parts. The sections are mounted in a relatively resilient manner by at least one resilient element (particularly a metal spring) to form a snap-fit connection. In the simplest case, the brush holder consists of two separate halves which are coupled by a yaw joint and at least one spring or, for example, by two springs. Flexibility is produced by this elastic effect, thereby achieving a snap-fit connection. This has the advantage that the retention area does not have to be overly elastic, for example, the sections or portions of the brush holder can be constructed of metal, thereby extending the life of the clamp.

The brush body clamp has a plate-shaped bottom portion through which the slit passes and a retaining edge protruding from the bottom portion, wherein the flexible segments respectively include: a segment of the plate-shaped bottom portion and a protruding holding edge. Thereby the retaining edges of the segments can be springed toward each other or opposite each other.

In the case where the unit consisting of the brush body and the brush body clamp has been inserted, the positioning unit optionally mechanically prevents the relatively movable sections from moving to the open position, thereby preventing the brush body from falling out.

The brush holder should preferably hold the brush body received in the brush holder without gaps, and of course retain it at least laterally and forwardly in a form fit.

Preferably, the apparatus of the present invention no longer directly captures the brush body during further processing. The brush body is locked in the device only by the brush holder.

Further, the present invention relates to a brush holder for a brush manufacturing apparatus of the present invention, wherein the brush holder has a receiving opening for a brush body to be inserted into the brush holder, the receiving opening The edge definition is maintained, wherein the retaining edge has at least one inwardly projecting stop towards the front side. Through this stop, the following effects can be obtained: the brush body is no longer easily pulled out of the jig during processing inside the brush manufacturing device. The brush body clamp is slit, and the slit also passes through the receiving opening to form a plurality of relatively movable sections, particularly elastic flexible sections, which allow insertion and removal of the brush body, The equal segments and the brush body form a snap-fit connection that can be released without breaking, and the segments are pressed against the brush body when the brush body is received.

As described above in connection with the brush making apparatus, the brush body clamp can have a flexible section that forms a snap-fit connection with the corresponding brush body that can be released without damage.

In particular, the brush holder has a plate-like bottom with an integrally formed retaining edge projecting from the bottom. As previously mentioned, the slit divides the bottom and the retaining edge into two sections or halves which can be brought together or separated such that the gaps become correspondingly larger or smaller. The segments are relatively springable, which is achieved by springs or through the segments in a U-shaped form at the ends.

In addition, it should be emphasized that the features of the brush holder described above when introducing the brush manufacturing apparatus of the present invention may also be directly provided for the brush holder.

The invention preferably relates to a kit of several brush holders having the same outer geometry but having different receptacles for different brush bodies.

Finally, the invention relates to a method of manufacturing a brush, the brush having a brush body provided with an opening for receiving the bristles, wherein the brush body is part of the finished brush and has a back side and a front side, After the brush is formed, the bristles protrude from the front surface, and are characterized by the following steps: inserting the brush body into the brush body clamp, the brush body clamp having a mechanical stop to prevent the brush body from being detached from the back surface toward the front direction The brush body clamp transfers the unit composed of the brush body and the brush body clamp to the transport unit, and the transport unit automatically feeds the unit (ie, by the driver) into the brush manufacturing device, and the positioning unit is used to clamp the brush body clamp In the manner of the upper gripping member, the unit is positioned in a further processing station, wherein the positioning unit only catches the brush body clamp, and in the case where the unit composed of the brush body and the brush body clamp has been inserted, mechanically The relatively movable sections are prevented from moving to the open position, thereby preventing the brush from falling out. The brush body is further processed and the unit is transported away from the further processing station and/or the brush manufacturing apparatus in a manner that jams the brush holder.

In the method of the present invention, the brush holder or the plurality of brush holders are not part of the apparatus, but are temporarily formed with a brush body of the brush holders to be automatically formed in a unit form ( That is, it is transported through the brush manufacturing apparatus by the drive, not by hand, and finally taken out of the brush manufacturing apparatus again.

The features described above in connection with the brush making apparatus are also relevant to the method of the invention and are equally applicable to the method.

In particular, the brush body is inserted into the brush body clamp without the gap in the brush body clamp using the snap connection. This gap-free retention occurs in all spatial directions.

Fig. 1 shows a brush manufacturing apparatus 1, which in the present example can perform various processing steps, and the present invention is not limited thereto. The brush making device has, for example, a rotatable feed table 5.

The feed table is generally a cube that is rotatable about axis A between four positions. A unit composed of the brush body 8 and the brush holder 9 is housed in the positioning unit 7 and mounted on the side of the cube. Different processing steps are performed at the four different locations, and the processing steps form a processing station.

The loading station 4 is realized at the top position. The unit formed by the brush body 8 and the brush holder 9 is inserted into the empty positioning unit 7 there. In particular, this is done in a fully automated manner. The illustrated embodiment is simplified.

The next step (rotation 90° clockwise) is to make a plug hole at the plug station, where the plug operation is carried out, for example, with an anchor.

To this end, the brush body 8 has a plurality of openings 20 which are sequentially filled by means of a plug tool 10. Symbol 11 is used to indicate the bristles and symbol 12 is used to indicate the separator.

After continuing to rotate 90° or 180°, the free end of the bristles 15 is then processed in this position, for example by cutting and/or grinding. Finally, the unit composed of the brush body 8 and the brush holder 9 is taken out from the apparatus again. This is done at a position rotated by 270° with respect to the loading station 4. This station is indicated by the symbol 13.

Of course, the brush body and the fixture of the brush body can also be removed from the feeding table and sent to other stations for performing a reworking step at which the bristles are subjected to, for example, cutting or round head processing. It should be emphasized that the illustrated device is merely an example, and that the device may perform only one of the aforementioned processing steps or perform other processing steps, and also need not be implemented in a rotatable feed station. A plurality of stations connected in series through a track may also form the apparatus of the present invention.

Figure 2 shows separately the positioning unit 7 mounted on the feed table, which forms the transport unit. The positioning unit 7 is fixed on the feeding table 5 during operation and is a fixed component of the device, and the unit composed of the brush body 8 and the brush body clamp 9 is only temporarily located in the device, and is sent before and after processing. In or out of the device.

The brush body 8 here is a brush body made by injection molding and has a plurality of openings 20 for plugging the bristles 15 into the openings 20.

The brush holder 9 is embodied as a standard piece, which is generally plate-shaped and has a flat back surface (also referred to as a bottom surface). The back surface is located on the same side as the back surface of the brush body 8, and the brush body 8 has a top surface as shown in Fig. 2. This top surface is the side from which the brush protrudes after the brush is made (see Figure 1).

Correspondingly, the brush holder 9 also has a top surface which points to the same side as the top surface of the brush body 9.

The brush holder 9 shown in more detail in Fig. 4 has a simple structured outer geometry comprising a side edge 20 having a plurality of parallel flat contact faces 22, 24. The gripping or alignment of the unit is easily achieved on these contact faces 22, 24.

The brush body 8 is held in the brush holder 9 through a snap-fit connection.

To this end, the brush holder 9 includes a receiving opening 30 which faces only the front side (see Fig. 4), only the back side (see Fig. 5) or the front side and the back side (Figs. 4 and 5). Combined) open. The accommodating opening 30 is defined by a retaining edge 32 that abuts at least in sections against the side edge 34 of the brush body and is pressed against the side edge 34.

The inner side of the retaining edge is provided at least in sections in a geometric shape which is complementary to the side edge shape and the outer peripheral shape of the brush body, so that the brush body 8 is fixedly mounted in the brush body clamp 9.

The section of the brush holder 9 (herein referred to as the section of the retaining edge that protrudes upwardly relative to the plate-like bottom) is of a resilient design. Additionally or alternatively, the entire brush holder 9 can also be formed entirely of resilient sections.

In the embodiment as shown in Figures 4 to 6, the brush holder 9 is of a slit design. The longitudinal slit 41 in communication with the opening 42 extends to the side edge of the brush holder to form two relatively movable sections, here two side edges 44, 46 which pass through the base side 48 are connected to each other. The side edges 44, 46 have retaining edges 32 (see Figure 4) and can be moved together or apart along the direction of the arrows in Figure 5, i.e., relatively movable. This shape allows the brush body 8 to be inserted into the accommodating opening 30 from above or in the longitudinal direction (see the arrow in Fig. 4). The opening 42 can also be used as a locating hole in the device.

In the embodiment as in Fig. 5, the slit 41 is expanded into a rear opening so that the brush body 8 can be inserted from the back side, and in the embodiment as shown in Fig. 6, the slit is evenly narrow.

In addition, it should be emphasized that the retaining edge 32 can also be divided into a plurality of small finger-shaped projections rather than having to consist of two elongated projections that abut the entire body edge against the brush body 9. The slit also extends through the receiving opening and the retaining edge 32 such that the retaining edge integrally protruding from the plate-like bottom of the brush holder 9 also has a plurality of sections.

The snap connection is designed such that the retaining edge 32 abuts against the top surface of the brush body 8, in particular: the retaining edge 32 has a stop 40 projecting inwardly in this region (see Fig. 4), the stop 40 is implemented in a lip style. Thereby, the brush body is prevented from being detached from the brush holder 9 upward (ie, from the back toward the front).

The section 50 of the brush holder 9 abutting against the top end of the brush body can further function as a stop and positioning aid in the direction of the arrow in FIG. 4, and can also have a stop 52 on the top surface of the section 50. This stop 52 prevents the brush body 9 from coming off the brush body clamp.

In this case, the relatively movable resilient section is the side edges 44, 46 that are resiliently joined by the two transmissive base edges 48, but may not be provided with slits 41, and only the retaining edge 32 is resiliently designed.

In general, the brush holder can be made of metal or plastic, which is suitable for all embodiments. It can also be manufactured using stereo printing technology (rapid prototyping).

In the embodiment as shown in Figs. 7 and 8, the brush holder 9 is of substantially the same design as that of Figs. 4 to 6, but the two side edges 44, 46 are completely separated rather than integrally joined, and there is no basis. Side 48. Thereby, a plurality of separate sections or portions are formed through the slit extending through the brush holder 9, and the sections or portions are pretensioned by the elastic members 50 (here, metal tension springs). Here, the aforementioned snap-fit connection can also be formed between the brush body 8 and the brush holder 9.

The shape of the brush holder is equivalent to that of the embodiment as shown in Figs. 4 to 6.

The embodiment of Fig. 9 differs from the embodiment of Figs. 7 and 8 only in that the two sides 44, 46 which are separated from each other and which are formed as separate portions are mutually joined at one end through bearings or hinges. connection. The elastic element 50 (here, for example a U-shaped torsion spring) brings the two sections together to form a snap mechanism.

Of course, a flexible plastic hinge can also be provided instead of the illustrated spring.

In general, the brush holder can also be implemented as a multi-component injection molded casting. A softer component connects two halves of a harder component.

It is also possible to always manufacture the same brush holders in the first step, in particular by injection molding techniques, and then individually adjust (ie rework, in particular by milling) the brush holders to suit the corresponding bristles. Carrier. Among them, for example, only a single milling or expansion of the accommodating port. Such a method for manufacturing a bristle carrier jig is the method of the present invention.

In the embodiment of Fig. 10, the brush body 8 is not a complete brush body as in the previous embodiment, but a small disk-shaped member provided with the opening 20, which is mounted on the electric toothbrush and Driven in the electric toothbrush.

A plurality of brush bodies 8 are inserted into the plate-shaped brush body jig 9 from the back surface (here, from below).

As shown in FIG. 11 , the brush holder 9 also has a stop 40 which is situated close to the top surface and which is embodied as an edge which projects inwards toward the receptacle.

As in the above-described embodiment, in the present embodiment, the accommodating port 30 is also designed to be at least partially complementary to the outer circumference and the outer circumference of the brush body 8. In the illustrated embodiment, a plurality of recesses 60 are provided in the region of the retaining edge 32.

This embodiment also prevents the brush body 9 from coming off the brush body clamp from the front side through the stopper 40.

Unlike the above-described embodiment, the present embodiment does not provide an engagement connection, but prevents the brush body 9 from falling downward by the clamping effect. Specifically, the accommodation opening 32 is slightly undersized with respect to the outer circumference of the brush body 8. Of course, this embodiment can also provide a snap connection.

As described above, the brush holder 9 of the present embodiment also has a plurality of flat contact faces 22, and the contact faces 22 are also partially pointed in opposite directions to facilitate the assembly of the brush body 8 and the brush holder 9. Positioning the unit and simplifying manufacturing.

It should be noted that the outer geometry of the brush holder 9 first remains the same in the sections of the section (sides 44, 46) against which the positioning unit 7 abuts, but the brush holder 9 is in the receiving opening. The 30 zones are of different constructions so as to accommodate different brush bodies 8.

The accommodation and fixing of the units in the device or at each station are illustrated by Figures 2 and 3.

The positioning unit 7 has a flat placement surface 62 on which the brush holder 9 is placed with the flat bottom surface of the brush holder 9.

The retaining shoe 64 on the placement surface 62 has an overhanging upper edge 66 that engages the plate-like section of the brush holder 9 in a manner similar to a snowboard fixture. At the other end of the brush holder 9 opposite thereto, a deflectable or movable fastener 68 catches the top surface of the plate-like section of the brush holder 9. After the unit is placed, the fasteners 68 are moved toward the retaining shoe 64, for example, by a preloaded spring or hydraulically, pneumatically or electrically. In the illustrated example, the fastener 68 is pneumatically deflected or moved to an open position, and the spring pressure moves the fastener 68 to the closed position.

The fastener 68 can also laterally grip the side edges of the brush body clamp 9 and push the brush body clamp 9 forwardly into the retaining shoe 64 against the retaining shoe 64.

Since the side edges of the brush holder 9 have an oblique angle forming a flat contact surface 24 at the contact area with the fasteners 68, the brush holder 9 is also laterally held and aligned between the two fasteners 68.

After the unit of the brush body and the brush body clamp is inserted, the fastener 68 of the positioning unit 7 is clamped from the outside to the section in the form of the side edges 44, 46, thereby preventing the relative movement of the brush body clamp 9 outward. The movement is moved to the open position, thereby mechanically preventing the brush body 8 from being taken out/pulled out.

Figure 13 shows a transport unit 70 having jaws 72 that are movable toward or away from each other, the jaws 72 gripping the brush holder 9 at the flat contact surface 22.

The brush holder 9 as shown in Fig. 10 has a beveled edge 74 on the transition between the side edge and the bottom surface for the claw 72 to be caught, and when the brush holder is required to be on the flat surface, so as to be able to be caught in the brush holder 9 below.

As shown in Fig. 13, the transport unit 9 places, for example, a brush holder 9 on the brush body 8 to form a unit.

Figure 12 also shows the transport unit 70, but in the present example, the transport unit 70 is not intended to form the unit described above, but rather to transport the unit into or out of the apparatus of the present invention. Here, the units are stationed or outbound or from one station to the next, wherein the brush body 8 can of course also be plugged or otherwise processed further.

Figure 14 shows an alternative plug station using these units. Here, the bristles are fashioned without being cut, but the bristles or tufts are unwound from at least one reel 80 and inserted into the opening 20. The bristles 15 or bundles of bristles are then cut from the bristles with a blade 82. If the holes are plugged from the back, the brush holder 9 has a correspondingly large opening on the back side of the brush holder 9 so as to reach the opening 20 in the brush body 8. For the sake of simplicity, the brush holder 9 is not shown here, but the brush body 8 is also permanently located in the holder of the brush body 8 on this station.

In the embodiment as in Fig. 15, the brush holder 9 is composed of a plurality of portions, i.e., two separately formed side edges 44, 46, on the top surfaces of which are connected panels 80. The side edges 44, 46 are located on the bottom plate 82, which may have a complementary arcuate configuration that matches the back side of the brush body 8.

In the front end region of the brush body 8, the connecting plate 80 slightly protrudes from the brush body 8 to form the stopper 32.

The side edges 44, 46 have a retaining edge 32 projecting slightly from the front side of the brush body 8 in the opposite side edge region of the brush body 8, which retaining edge 32 forms a stop 40 in this region.

A spring (not shown) provided between the side edges 44, 46 presses the side edges 44, 46 against the brush body 8. To this end, the side edges 44, 46 are pivotally mounted on a shaft 84 that connects the web 80 to the bottom plate 82.

As shown in Fig. 15, the front end of the bottom plate 82 has a wedge-shaped beveled edge 88 through which the bottom plate 82 is pressed into the substantially complementary slit of the retaining shoe 64 for lateral and vertical fastening.

Further, the side edges 44, 46 have a wedge-shaped bevel 90 that is slightly upwardly directed at the ends of the sides 44, 46 opposite the retaining shoe 64. The bevel 90 is also inclined relative to the sides 44, 46 in addition to the upward slope. The vertical axis is inclined. The fastener 68 has an upwardly tapered extension end 92 that is deflected toward the axis 94 to close the positioning unit 7. In the closed position shown in Fig. 15, the tapered end 92 is pressed against the ramp 90 to lock the sides 44, 46 on the one hand to prevent the sides 44, 46 from moving apart from each other. On the other hand, the side edges 44, 46 are also depressed so that the unit of the brush holder 9 and the brush body 8 is also vertically positioned in this area.
