Washing brush with a hollow handle through which the detergent flows

Field of application of the invention

The invention relates to a washing brush with a hollow handle through which the detergent flows and a securing of the connection between the handle and the bristle carrier and a shut-off or throttling device through which the amount of detergent supplied to the bristles and the direction of the jet of detergent is changeable by means of and which is particularly suitable for an application | is suitable as a car wash brush.

Characteristics of the known technical solutions

Washing brushes with a hollow handle, over which the washing liquid is fed to the brush head and with the handle of which an adjustable valve is connected through which the dem The amount of liquid supplied to the brush head can be changed, are already known from DE-OS No. 21 53 439. The solution has the disadvantage that it is at the junction between the handle and the brush head when working with the The wash brush and the handle on the brush head

Manual pressure exerted on the seal between the brush head and the handle on one side, the connection loosens, creates unevenness in the seal or it is worn on one side, so that leaks occur there, Detergent comes out and the hand is wetted. ”Another disadvantage of this solution is that it is not possible is, the handle opposite the brush head rotatable around a center in the brush head, parallel to the bristles Axis, to be adjusted and locked at different angles.

The shut-off device for changing the amount of detergent supplied to the brush head is complicated and requires a large number of labor-intensive individual parts. The handle is arranged outside the center of the brush body on the latter. That means poor handling . the washing brush during the washing process, because the large distance - _: stand of the handle from the center of the brush body, through

These long lever arm, considerable physical effort is required to manually exerted on the handle arrival f compaction pressures on the brush head are effective to make.

The same operating defects also occur when using the car wash brush with water supply by handle according to DE-AS Ϊ Kr. 16 57 311 on.

^ brush is the brush head made of an elongated bristle carrier and the bristles anchored in them. | "The handle is essentially in the middle of the brush head attached to the bristle carrier at an angle to the axis of the bristle carrier, so that the handle is attached to the bristle carrier at right angles and attached to the bristle carrier so as to be rotatable about an axis parallel to the bristles and provided with a lock is. This solution allows the handle to be in any position in the angular range of approximately + 45 ° to that of the bristle carrier bring perpendicular direction. However, it has the disadvantage that with the selected pivotability the locking

by tightening the connecting screw must, which connects the brush head and the handle together. The two parts are clamped together only on two very small surfaces that are clamped against each other. If this connection is stressed on one side only, loosening can be achieved enter after a short use of the toothbrush, or a commercially available nut or knurled nut must be used for tightening the connection are provided, but interferes with the use of the toothbrush.

A supply of detergent through the handle of the toothbrush to the bristle carrier is not provided in this solution and also not possible because the adjustment mechanism would be in the way. Another known toothbrush shown in DE-GM Ur ₀ 78 H 122, which also has a 3üi ^% -stenkopf adjustable transversely to the handle, enables the handle to be adjusted to the brush head at an angle of 90 °. The brush head and the handle can be adjusted with respect to one another by a snap-in catch in the form of a point projection on the handle or brush head and corresponding depressions in the brush head or handle that define the catch positions. This offers the advantages of an adjustable curl position in which the brush head and the handle are aligned with one another like a conventional toothbrush, and that the brush head can be rotated and exchanged through 360 ° with respect to the handle in one direction as well as in the opposite direction , but this snap-in locking does not guarantee that the connection of the brush head with the handle is not leak-proof. If detergent is fed through the handle into the bristles, leaks in front of the bristle carrier would also be unavoidable here, where the detergent would escape and run over the hand of the user. Sooner or later this would also be the case if an additional seal were provided at this point. Their early wear could not be avoided, because the element that connects the two parts with one another only allows a loose, mechanically held connection in the long run, which requires frequent re-tensioning.

A well-known broom according to DE-GOI Rr. 80 18 171 has on the free A hose connection at the end of the broomstick. In the area of the bristles there is at least one with the inside of the broomstick related water outlet nozzle arranged. These or more such nozzles are parallel to the longitudinal axis of the Broom body, provided between the bristles, parallel to them · Distribution and supply channels to these nozzles run in the broom body «

This known solution has the disadvantage that the The jet of washing liquid, parallel to the bristles, is directed through the water outlet nozzles onto the surface to be cleaned and the amount and direction of the emerging water cannot be changed. Another known brush or a known broom with liquid supply to the brush body are in the DR-PS No. 1 37 099 described, the hollow handle in the nozzle of the brush body penetrating, against the Bristles is screwed towards the perforated tube. This is afflicted with the shortcomings that a change in the amount of exiting washing liquid and a change in the Direction of the liquid jet is not possible. Such an adjustment of the broom body transversely to the handle about a central axis of the broom body that is parallel to the Bristles running is not possible because the handle, at a slight angle of inclination to the surface of the broom body, is fixedly arranged on the latter, that is to say the broom body is not arranged so that it can be rotated around the handle "

Object of the invention

The invention aims at a quick, convenient handling and convenient use of the washing brush in the To enable cleaning work. Loss of detergent and wet hands should be avoided, but space-saving storage and packaging of the washing brush should be ensured.

Furthermore, it should be easier, more convenient to change the amount and jet direction of the detergent supplied can be achieved.

Explain the essence of the invention

The invention is based on the problem of the technical causes to eliminate the shortcomings of the known solutions described above and in particular with a washing brush to design a hollow handle through which the detergent flows, the connection of the handle with the bristle carrier is tight and adequately secured. It should be designed with a shut-off device through which the The amount of detergent fed to the bristles and the direction of the jet the detergent can be changed. The washing brush should be particularly suitable for use as a car washing brush be.

For this purpose, manual pressure on the center of the bristle body during the washing process and more effective work with different washing widths should be possible f , through a quick and convenient possibility of obstructing the angle between the handle and the bristle body, | transversely to the handle or running at the same time without the handle handle and the bristle body having to be completely separated from one another.

On the way from the handle to the detergent dispenser, separate, Interconnected parts are avoided in order to prevent leaks from occurring in the first place. For quick, space-saving storage and packaging, the washing brush should be easy to dismantle into just a few individual parts After assembly, the connection between the handle and the bristle carrier is firm and free of play, despite frequent dismantling be.

The separation of the handle from the bristle carrier should only take place in two specific angular positions of the handle to the bristle carrier may be.

Furthermore, the detergent dispenser should at the same time be suitable for providing the connection between the handle and the bristle carrier.

additionally secure and an easy and convenient change the detergent passage openings and the jet direction of the Enable detergent.

According to the invention, the handle of the washing brush is preferably angled at right angles to the handle and is similar to that of toothbrushes well known, arranged essentially in the middle of the brush head or boron part carrier.

This has the advantage that the pressure exerted by the hand of the user during the washing process on the handle and thus on the bristle carrier is on the latter near the center of the bristle carrier takes effect.

The bristle carrier is at right angles to the handle handle. the bristles parallel axis adjustable so that between Handle handle and bristle carrier preferably form an angle of 90 ° of the full circle of 360 °.

The bristle carrier can be adjusted at different angles across the handle and in these angular positions lockable and firmly connected to the handle. This means that different washing widths can be selected, depending on whether the bristle carrier is set in the longitudinal direction concurrently with the handle j or transversely thereto.

The bristle carrier can also be completely detached from the handle and thus interchangeable «

This is possible because the angled opening part of the handle penetrates the bristle carrier in the middle. The hollow, preferably tubular handle stem consists of a single piece. Therefore there are no possibilities for leaks in front of the bristle body, i.e. in the area of the operating hand, as is the case with known solutions, where the handle is releasably connected to the bristle body by screwing, etc. Enable detergent.

A releasable clamp connection is provided between the bristle carrier for quick and easy connection of the handle with the bristle carrier provided in both parts.

For distributing the wax between the tufts of bristles a detergent dispenser is adjustable and detachable attached to the mouth of the handle stem.

The releasable clamping connection between the handle and the The bristle carrier consists of wedges and keyways as well as one Screw connection, which, however, only serves to secure the clamp connection so that this clamp connection cannot loosen by itself due to the stresses during the ash process. The clamp connection is also a means for angular adjustment and locking of the Bors th carrier relative to the handle in the selected angle setting by rotating the wedges introduced into the associated keyways Do not allow bristle carriers on the handle. Such a clamp connection is due to the adjacent increasing wedge clamping surfaces self-adjusting when worn and therefore always largely free of play when the securing screw connection is tightened accordingly and the tightening force is applied axially to the wedge clamping surfaces of the wedges and keyways takes effect.

The wedges can, for example, be arranged on the outside of the circumference of the muzzle part and be designed as ribs running radially and parallel to the longitudinal center axis with wedge-tightening surfaces. The keyways can be arranged, for example, in the opening in the bristle carrier for the handle, that is to say in the bore.

Of course, the wedges in the opening and the keyways on the circumference of the mouth part can just as well be provided if the wall thickness of the latter is sufficient * To the bristle carrier from the mouth part of the handle despite to be able to disconnect the clamp connection, for example to pull it off or to be able to rotate it to a different angle setting, are apart from the keyways in pairs opposite unlocking grooves, which allow the wedges to pass freely through, in a certain angular position for unlocking, for example under 45 ° of the full circle of 360 ° to the handle, arranged.

The screw connection serving as a fuse for the clamp connection consists of an external thread arranged on the circumference of the handle and a union nut with one on it matching internal thread «

The play-free clamping connection between the handle and the bristle carrier is secured when the union nut on the external thread with its front tightening surface is under compressive stress rests against the back of the bristle carrier There is a distance between the wedges of the clamping connection, for example on the circumference of the mouth part, and the external thread Provided at least as thick as the bristle carrier plate so that the keys and keyways disengage at this point stays when the bristle holder is on the handle Position to be rotated to a different angle to the handle.

Near the mouth is on the mouth part of the Sriffetieles a further external thread is provided, to which the detergent distributor, designed for example as a screw cap, can be adjusted is screwed on.

The possible leaks at this screw connection can must be accepted because the intention is anyway to distribute the detergent between the tufts of bristles. The screw cap is V-shaped, widening towards its rend Recesses formed.

The same V-shaped recesses are also on the hands of the handle stem mouth intended. Depending on whether the screw cap is far or less on this external thread at the mouth of the Handle is screwed on, form the matching V-shaped recesses smaller or larger openings for the detergent.

There are only two on the screw cap, but on the mouth of the handle four such opposing V-shaped recesses are provided, then the direction of the beam is changed according to the selected angle setting of the bristle holder to the handle possible by placing the opposite two recesses on the screw cap into one

Direction can be adjusted concurrently with the longitudinal center axis of the bristle carrier. In this position the Screw cap which is arranged in the direction of the longitudinal center axis of the handle at the mouth of the handle shaft V-shaped recesses, but gives a part of the V-shaped recesses at the mouth of the handle stalk freely pointing in the direction of the Show the longitudinal center axis of the bristle carrier, that is, in a beam direction transverse to the handle «Such a setting of the V-shaped Recesses in the screw cap must always be made, regardless of whether the bristle carrier is perpendicular to the handle or with it is set and locked in the same direction. The detergent distributor, for example designed as a screw cap, is also an additional safeguard for the | Connection of the handle to the bristle carrier by | an unintentional unlocking and solution of the bristle end; gers from the handle handle even if the wedges | the clamp connection by twisting the bristle carrier | have already entered the unlocking grooves on the muzzle part. The setting of the angular position of the bristle holder to the handle and the connection of the mouth part with the bristle holder for the washing process is carried out as follows. First, the bristle carrier with its unlocking grooves opposite one another in its bore is attached to the Muzzle part of the handle is pushed at an angle of 45 °. The wedges pass the unlocking grooves free up to the stop of the back of the bristle carrier against the external thread on the circumference of the handle shaft near the handle. Now the bristle carrier is clamped on this part of the handle between the external thread and the wedges in the desired, for example, longitudinal or transverse position, rotated to the handle and then the muzzle part of the handle the wedges are drawn axially in the bore of the bristle carrier into the associated keyways until the two parts are wedged entry. The clamp connection is then secured by tightening the union nut until it meets its tightening surface

rests firmly against the back of the bristle carrier. Then the screw cap of the detergent dispenser screwed onto the external thread at the mouth of the handle, until the V-shaped recesses leave a passage opening of the desired size for the detergent and / or the desired one Beam direction is set. The wash brush is now ready for use.
