Handle brush with container

The invention relates to a simple and useful design of a Handle brush with container, such as can be used as a toothbrush in luggage. Such a brush should namely, on the one hand, be as short as possible in order to take up as little space as possible, and on the other hand long enough to cover them to be able to operate comfortably and properly.

The purpose of the invention is to create a stick brush with a container, which easily meets both requirements.

Such a handle brush with a container is characterized according to the invention for this purpose by a handle made of two telescoping parts and a container with an inner constriction near the Entry opening against which the bristles abut when the brush inserted in the axial direction of the handle into the container or out of the Container is pulled out. .

The handle here expediently consists of a tubular one Part within which a rod-shaped part carrying the bristles at its outer end is axially displaceable, and also Locking devices at the outer ends of the handle parts for Holding the stem in the extended position can be provided can. These locking devices can easily consist of at least one rubber ring on a handle part and a corresponding one There are annular groove on the other stem part, which interlock in the extended position and the telescopic displacement of the two Block the handle parts against each other. - "'

The aforementioned constriction is advantageous with one in one outer longitudinal groove of the handle sleeve provided sliding edge, the inner end of which runs obliquely outwards and thereby a clamping of the handle in the container as soon as the handle brush is fully inserted into the container.

Due to this advantageous design, the brush handle pushes itself automatically when pushing the brush into its container and pulls itself apart again as soon as the outer brush part is pulled outwards.

In the accompanying drawing is an exemplary embodiment the stick brush according to the invention with a container in the form of a toothbrush shown, where show:

Figure 1 is a side view of a longitudinal section and

Figure 2 is a view of the container from the opening side.

According to this, the brush handle consists of a tubular part 1, within which a rod-like part 2 slides with friction, which

the bristles 3 of the brush carries. The stem part 1 is on its outer Closed at the end, with the front wall being worked out slightly to the outside. This protruding part forms a stop as soon as the handle brush is inserted into its container 5.

The upper end of the stem part 2 carrying the bristles 3 is provided with two Ring grooves 6 and 7 are provided, within which two solid rubber rings 8 and 9 sit. The open end la of the tubular handle part 1 is provided in a corresponding manner on its inner wall with two unspecified annular grooves in which the two rubber rings 8 and engage as soon as the stem is in its extended position is, as it is in the upper part ^ of Figure 1 in solid lines is shown. In this way, these two rubber rings 8 and secure a locking of the two handle parts in the pulled apart position.

The container 5 is provided with an air hole 10 in the usual manner and has an inner constriction 11 below its inlet opening, which is delimited upwards and downwards by a slope. In your In the middle part, this constriction 11 is equipped with a longitudinal rib 13 which terminates in an edge 14 at its inner end.

When the stick brush is pushed axially into its container, they meet Bristles 3 on the constriction 11, the mechanical resistance of the bristles being sufficient to remove the rubber rings 8 and 9 from the annular grooves allow the tubular stem part 1 to emerge. After that, pushes itself the other handle part 2 in the tubular handle part 1 axially into it until the upper end of the handle part 2 on the closed bottom of the tubular Part 1 meets. A further, somewhat stronger pressure can bend the bristles 3 so far that they are at the constriction 11 can sweep by. After the brush has been completely inserted into its container 5, it assumes a position like the one in the lower part of Figure 1 is shown in dash-dotted lines.

The tubular stem part 1 is also on its outside with a Provided longitudinal groove 15, in which the mentioned inner edge of the constriction engages, so that a proper guidance of the brush handle when inserting and pulling it out of the container is ensured. At the same time, in the completely inserted position, the diagonally follows out-sen extending end 16 of the longitudinal groove a clamping of the handle in the container by engaging the rib 13 in the beveled Groove end 16.

When the brush is then pulled out of its container, hit the bristles 3 in turn form the constriction 11 and brake the outward movement of the tubular stem part 2, whereupon by further train the tubular stem part 1 is further pulled out from sen and through Engagement of the rubber rings 8 and 9 in the mentioned ring grooves automatically the two handle parts are blocked in the extended position. The lower end 17 of the tubular handle part 1 can here suitably be provided with a radially inwardly directed projection, which an unintentional separation of the two handle parts 2 and 1 prevented.

In a modified embodiment, the rings 8 and 9 can also be worked onto the inner wall of the tubular handle part 1 right from the start and then snap into corresponding annular grooves on the outer circumference of the inner stem part 1. Incidentally, it is not absolutely necessary for the two handle parts to be as precise with their dimensions are coordinated $ that they slide into each other with friction, since mutual locking is necessary only in the extended position.

The two rubber rings 8 and 9 can also be omitted, whereby then the handle in its extended position solely by means of

Cracks at the end of the tubular stem part is held. The other stem part 2 is provided with a thickening in this case, which gradually rise from the bristles after the end of this Stalk part extends.

Of course it is possible to interlock between the two Handle parts in the extended position also in other ways effect, for example by means of a latch or a resilient ball, which engage in corresponding recesses.
