Abstract

A toilet brush 1 with articulated connection 5 between the brush head 4 and brush handle 3 has a targeted blockage or blocking of the pivot joint 10 formed as an articulated connection 5 in one of the two possible pivoting directions. For this purpose, the pivot joint 10 is formed by the two fork ends 32, 33 end of the brush handle 3 and an axis 11, wherein the fork ends 32, 33 allow the side pivoting 15 to the other side 16 but lock out because here the two fork ends 32nd , 33 are connected to each other via a locking shell 41 and prevent the pivoting. This locked, articulated connection 5 once allows the cleaning of the spout of the toilet bowl very intense, because the brush head 4 is bent up when pushing through and then can clean the upper area of the spout with. In addition, when turning the toilet brush 1, this articulated connection 5 is locked at the same time and can clean the rest of the toilet bowl with the appropriate pressure and again with the curved brush head 4, the inner trough at the top of the toilet bowl. This improved cleaning effect is further optimized by the fact that virtually the entire brush head 4, especially with the bristles 6, 7, 8 made of flexible, hygienic material.

Description

The invention relates to a toilet brush with a handle, a brush handle and an end brush head, wherein brush handle and brush head have an articulated connection with each other and wherein the bristles distributed around the bristle carrier and formed of a Kotreste and lime from the toilet bowl dissolving material.

The toilet brushes usually commercially available and distributed by the trade have a brush head which is rigidly connected to the brush handle. The brush head forming bristles are usually made of plastic, wherein they are needle-shaped and made of hard plastic formed. Associated with this is the disadvantage that these bristles made of hard plastic partially bring the faeces into the brush head, so that a subsequent cleaning of the toilet brush is absolutely necessary. Moreover, it is hardly possible with these known, rigid brushes to completely clean the transition from the toilet bowl into the drain and also to liberate from limestone and similar hard components.

In order to enable in particular the latter toilet brushes have been developed with a joint between the brush handle and brush head. They are now commercially available, with patented joints used by an American patent, which make it possible to move the toilet brush in all directions. Apart from the fact that these newer toilet brushes have the usual hard bristles, the mobility of the brush head in all directions has the disadvantage that, for example, in the toilet bowl adhering Kotreste or other solid ingredients can not be removed optimally, because the brush through the joint too much yields and avoids the pressure. Further, it is not possible with these known brushes to clean the inner channel of the toilet bowl through which the fresh water flows in, because both the rigid version of the toilet brush as well as allowing the movement in all directions joint allowing the insertion and movement in this groove do not allow. Finally, toilet brushes are also on the market, which instead of the joint have a thinned zone of the brush handle in the transition to the brush head, this dilution still allows better movements that it runs undulating. But so that the same drawbacks are present, which are also present in the articulated connection, or it must be very important to ensure that when cleaning the toilet bowl, the brush is placed and held in the appropriate "rigid" position. In addition, even if the brush is held in the correct position, it may cause pivotal movements and overload of the "weakened" zone.

The invention is therefore based on the object to provide a well-suited for the cleaning of the outflow region of the actual toilet bowl and at the same time the inner edge of the toilet brush.

The object is achieved in that the articulated connection is designed as a pivotable about an axis pivot, which is designed to one side by more than 90 ° movements permitting and locked to the other side and that the bristles are made of hygienic, flexible plastic material.

This swiveled to one side swivel joint allows it without problems, with the necessary high pressure, the toilet brush, for example, in the toilet bowl to move back and forth to remove the existing debris. On the other hand, the toilet brush can be pivoted or moved in relation to the brush handle by more than 90 ° in order to safely reach and clean the upper area of the tubular drain when it is introduced into the drain. The bristles of the brush head can be selectively reciprocated with sufficient pressure without overburdening the brush head. In addition, there is the possibility to clean with the same brush head and the groove at the top of the toilet bowl with, because the pivot joint movement by more than 90 °, d. H. for example, up to 140 °. The brush head can thus be brought into a position where it can be moved back and forth in the groove and in the optimal position for cleaning. The bristles themselves are not made of the hard plastic as in the prior art, but rather of a hygienic and flexible material, ie soft to medium-hard plastic. They nestle when pressed onto the toilet bowl and also when moving against the pipe of the drain to this and can safely solve by loosening the there-sitting dirt, so that an advantageous optimal cleaning success is recorded.

In a further development of the pivot joint, the invention provides that the articulated connection to the other side is formed lockable. It is conceivable for this purpose that when a Verstarrung the pivot joint is necessary, simply a sleeve is pushed over, so that the effect of the pivot joint is turned off.

The bristles made of the flexible material can their cleaning effect especially fulfill well when the bristles are arranged in the distance arranged straight aligned to the brush tip combs. These combs can thus move to the sides or in all directions and thus optimally fulfill their cleaning effect when moving the entire brush head back and forth. The combs have this for a distance that corresponds for example to half their length.

A further advantageous possibility to increase the cleaning effect of the bristles is that in which the combs are arranged undulating. This excludes that, for example, when sweeping in the longitudinal direction of the brush handle zones on the bottom of the cymbal are not properly achieved with.

In particular, with frequent use of the toilet brush, wear on the bristles ultimately can not be prevented. The prior art has therefore provided, for example, to connect the brush handle and the brush head by a screw. Apart from the fact that the production is expensive, it must always be ensured that the thread of the brush head and the brush handle match. In order to remedy these problems, the invention provides that the bristle carrier is designed as a sleeve consisting of elastic material, in the sleeve opening of which an extension attached to the axle can be inserted with resistance. This can be achieved by simply pulling this extension of the sleeve separation of the brush head from the brush handle. Conversely, the extension simply has to be inserted into the sleeve opening and then inserted into the sleeve with some resistance. Due to the friction between the sleeve and extension unintentional separation of the brush head is avoided by the brush handle.

The extension is not designed as a round rod or the like, because then a twisting of the sleeve would be conceivable on this extension, but the extension, which is attached to the axis perpendicular to this axis, is formed sword-shaped with respect to the blade and tip. A twisting of the sleeve on the extension is therefore not possible. The tip facilitates insertion into the sleeve opening and insertion into the sleeve.

This extension, which gives the brush head the desired mobility, must be pivotable about the axis, the invention provides that the extension has a sword knob which is comprehensive and at the same time insertable between the fork ends of the brush handle between them formed. For a simple and very convenient connection between the brush head and the brush handle is given, which can also be dissolved if necessary, as will be mentioned later.

This release of the connection is possible according to an embodiment of the invention in that the axis is formed as the fork ends durchhörende screws with screw head and nut. In addition, however, there are other possibilities, such as appropriate approaches to the sword knob, which are inserted into corresponding blind holes in the fork ends, the connection is relatively easy to produce, because the fork ends or the entire brush handle is made of appropriate plastic.

The locking of the pivot joint in one of the two possible directions is made possible by the fact that between the blade and sword knob over the blade protruding annular body is arranged. This ring body is then designed so that it gives the mobility in one direction of the blade, while being locked in the other direction.

A further possibility of blocking in one direction is possible because the annular body has on one side of the ring a semicircular locking shell comprising the fork ends. This locking shell, which is usually part of the brush handle or the fork ends, gives the blade or the extension the ability to swivel out to one side as far as it is necessary, so for example 140 °, while on the other hand, the movement of the Blade or extension is not possible.

An expedient extension then provides that the locking shell pivoting about 10 ° - 30 ° relative to the center line permitting, so that the cleaning of the curved toilet bowl can be improved again.

Earlier it has been mentioned that the bristles should consist of a special limited yielding material, so as to favor a targeted nestling on the surface to be cleaned. A targeted cleaning can be further improved according to the invention, characterized in that the bristles are spherical at the free end, which in particular prevents that Kotreste or the like are skewered and then again require a separate cleaning.

Another possibility of forming the bristles is that they have at the free end blade-shaped end pieces, which should improve the cleaning effect targeted.

Another solution is the one where the bristles have a sharpened tip at the free end, which of course is something again Problems can bring, because it can not be countered with the impaling of Kotresten.

Instead of a round brush head is also given the opportunity to give the brush head a rectangular shape or vertical lens shape. The resulting "edges" can increase the cleaning effect.

In order to give the here from limited flexible material brush head a certain flexibility in the tip area in addition, the invention provides that the sword-shaped extension receiving sleeve opening is carried out reaching to the center of the sleeve. This leaves the head end a certain mobility, which is not hindered by the stiff sword-shaped extension.

Earlier it has been mentioned that in the prior art, the difficulty exists or does not exist to clean the existing at the top of the toilet bowl groove through which flows the fresh water to clean. This is facilitated by an embodiment of the invention characterized in that the sleeve and thus the brush head is formed having a fist-like end piece. This tail is suitably sized so that the insertion into the groove in any case is still possible in such a way that even the bristles located there can still operate cleaning when the toilet brush is moved back and forth.

The invention is characterized in particular by the fact that a toilet brush has been created, which is ideally suited both for the cleaning of the outflow region of the actual toilet bowl as well as the inner edge. This new toilet brush also cleans the spout even deeper, especially in the upper part of the drainage pipe, without the need for a special cleaning brush for this area. Due to the "flexible" cleaning by the limited articulated bristles not only a gentle cleaning but also a very intensive cleaning can be achieved. This saves cleaning agents and protects the environment. With the toilet brush according to the invention, not only the more or less hard Kotreste be removed, but also deposits of lime and urine stone, if they should have formed and especially lime residues in the upper inner edge can be processed so advantageous and very intense.

1 shows a toilet brush 1 whose handle 2 has a special training to the effect, as the gripping surface here as an elastic wave grip 12 is trained. In this way, at the same time a wave eye 14 formed, hanging the toilet brush 1 facilitated.

To the handle 2 is formed, for example, a round brush handle 3 , the end with the brush head 4 over a hinged connection 5 connected is. The articulated connection is closer in 2 played.

The brush head 4 has a variety of bristles 6 . 7 . 8th that with a bristle carrier 9 are connected and different combs 20 . 21 . 22 form, so by their mobility at the same time to improve the cleaning effect of the toilet bowl.

2 clarifies that the swivel joint 10 This is an articulated connection 5 to use comes to page 15 allows for more than 90 ° of agility, while moving towards the other side 16 Is blocked. More details later. About an axis 11 is an extension 25 articulated with the brush handle 3 connected. As shown by the further figures, this extension exists 25 over a blade 27 with lace 18 as well as a sword pommel 29 , for example, for the connection to the axis 11 is needed.

The brush body 19 corresponds here after 1 basically that of the prior art, with the brush tip 18 in particular can be trained as the comb formed there 23 can also be designed as a kind of disc with stiffened bristles so as to optimize the cleaning effect again.

The 3 equals to 2 , Here, the components are slightly shifted in perspective. Recognizable, however, is both in 2 as in 3 that the extension 25 in the direction of the midline 42 from brush handle 3 and brush head 4 runs. The perspective further shows that this is toward the midline 42 extending part, namely the extension 25 around the axis centerline 26 is pivotable in one direction while being locked in the other direction.

4 shows this tilted position, where 4 and 5 show that the fork ends 32 . 33 the brush handle 3 the upper end of the extension 25 , here as a sword knob 29 is formed, certainly include. Whether now as shown here on the screw 34 , Screw head 35 and nut 36 as an axis 11 is worked or whether another training is chosen, in any case, by this particular training the extension 25 be pivoted only in the direction shown here, so that the brush head, not shown here 4 is placed in a position from where, for example, he can intensively work and cleanse the discharge.

The sword-shaped extension 25 with her sword pommel 29 has a ring body 39 on, on the one hand ring side pivoting the extension 25 allows while the other side is blocking.

6a and 6b show this training with the ring body 39 below the sword knob 29 ,

In 7 is again the toilet brush 1 with handle 2 , Brush handle 3 and brush head 4 shown, with the brush head 4 a sleeve 24 that's over the extension 25 can be pushed over after the preceding figures, the sword-shaped training twisting the sleeve 24 and thus the brush head 4 does not allow. The brush head 4 itself has a special form insofar as it has a fist-like tail 50 has that allows the insertion into the inner groove of the toilet bowl, not shown here advantageously so that thus an optimal cleaning effect can be achieved when this brush head 4 with the fist-like tail 50 in this groove is moved back and forth.

Next shows 7 that not only has the possibility of a locking shell 41 to use that part of the brush handle 3 is, as shown in the preceding figures, but also a corresponding approach to the sword knob 29 or the ring body 39 ,

This is based on the 8th again clarified, in which case in particular the rectangular shape 52 to mention, that the entire brush head 4 is awarded.

Another way of forming the brush head 4 is in 9b shown where different from the illustration in 9a here a lens shape 53 is shown, which makes nestling advantageous to the bottom of the toilet pan, while turning the cleaning effect simultaneously improved.

In 9a and 9b is in the middle of the brush heads shown 4 the sleeve opening 9 shown in the sword-shaped extension 25 should be introduced. Next shows 8th that this sword-shaped extension 25 not up to the brush tip 18 is enough, but only to about sleeve center 48 ,

10 Finally, shows special formations of bristles 6 . 7 . 8th where once the free end 44 as a scoop-shaped end 45 is reproduced as sharpened tip 46 or as a punctiform tip 47 , All shapes of the free end 44 the bristles 6 . 7 . 8th should support the cleaning effect.

In the 11 and 12 is again clarified, such as a particularly appropriate training the articulated connection 5 should look like. At the in 11 shown position, the sword-shaped extension 25 in the direction of the spectator freely, while in the opposite direction, which in particular 12 clarifies the locking shell 41 such a movement towards the viewer does not allow. Here is the locking shell 41 and are the fork ends 32 . 33 formed in one piece.

All mentioned features, including the drawings to be taken alone, are considered to be essential to the invention alone and in combination.
