DE8803225U1 - Cleaning device round brush for toilet and urinal bowls - Google Patents

Description

The invention relates to a round cleaning brush to be used in a cleaning device for toilets and urinals.

10

Cleaning toilet and urinal bowls, especially in larger toilet facilities such as those found in public toilets, guest houses, hotels, schools, hospitals, etc., is a laborious and unpleasant task when using the hand cleaning brushes we have known so far.

The invention is based on the object of creating an improvement that enables quick, thorough and pleasant cleaning of even larger numbers of toilet and urinal bowls.

This object is achieved according to the invention by the round cleaning brush characterized in claim 1.

The invention thus creates a motor-driven round brush for use in a device that can be moved over a pool to be cleaned and then allows convenient cleaning of the pool with a telescopically movable and all-round pivoting holder for the cleaning brush.

Advantageous embodiments of the brush according to the invention are the subject of the subclaims, which speak for themselves and are so easily understandable that further explanation is not necessary. It is only worth mentioning in detail that the dense, closed cover bristle ring consisting of soft bristles serves as a splash guard or splash guard against water whirled up by the rest of the brush in the wet brush and that this brush ring with Different bristle lengths and bristle inclination angles enable intensive and complete cleaning not only of the easily accessible areas of the basin to be cleaned, but also of corners, angles, in the drain and under sink rims.

An embodiment of the brush according to the invention is shown by way of example in the accompanying drawings and is described in detail below. In the drawings:

Fig. 1 A cleaning device in schematic

perspective representation, and

Fig. 2 the cleaning brush in schematic Axial section.

According to Fig. 1, a cleaning device has a mobile bridge-like frame 1, which consists of a U-shaped base frame la provided with castors and a support bracket 1b connected to it and projecting upwards*

In the middle of the support bracket Ib, a telescopic arm 11 is pivoted in all directions by means of a ball joint 8, the downwardly extendable part of which has a built-in motor mount 6 with an electric motor 7 and carries a cleaning brush 5 attached to its lower end. The

The extendable lower part of the telescopic arm 11, which is equipped with a power tool and a cleaning brush, is pre-tensioned into its uppermost position by means of a tension spring 12 housed within the telescopic arm. Furthermore, an operating handle 9 with a switching handle 10 arranged thereon for switching the electric motor 7 is attached to the extendable lower part of the telescopic arm.

Control box 3 contains a motor control that ensures

&Ggr; that the motor 7 is switched on again via the

'■ ' Switch handle 10 changes its direction of rotation. |i

The cleaning brush 5 is, as shown in the

! 15 arrows, longitudinally adjustable and pivotable in all directions and direction of rotation reversible.

The electrical supply cable 4 for the electric motor can run inside the frame 1 designed as a tubular frame.

' The cleaning brush 5 shown in Fig. 2 represents

a concrete example with the following features ): 25

The uppermost bristle ring A is a relatively dense

; Bristle ring snu long soft bristles formed and

^; serves as a splash guard or as a splash guard for the

Rotating movement of the cleaning brush stirs up water.

In the specific example, 30 stock exchanges have a (from

Brush body (measured) length of approx. 80 mm and

by about 10° downwards (relative to the vertical cred'-hte

Brush rotation axis) is inclined.

The next two bristle rings B and C each have bristle lengths of approx. 60 mm and their bristles are inclined upwards by approx. 6° and 12° respectively.

The following three bristle rings D, E and F each have a bristle length of about 50 µm and their bristles are arranged horizontally or inclined upwards by about 2G° or again horizontally.

The next bristle ring G has a bristle length of approx. 70 mm and a bristle inclination of approx. 15° upwards.

The bristles of the bristle ring H are approx. 40 mm long and inclined downwards by about 20°. The bristle ring I

with a bristle inclination of approx. 50° downwards, V has longer bristles, namely approx. 50 mm long.

The other bristle rings K, L and H each have bristles that are approx. 30 mm long and bristle inclination angles of 50° or 80° downwards or parallel to the axis of rotation (bristle ring M) .

Of the bristle rings B to M, the bristle rings F and I consist of soft bristles, the remaining bristle rings of hard bristles.

While, as already mentioned, the crown of bristles A is a circumferentially densely closed crown of bristles, the other crowns B to H each consist of about 7 to 12 individual bundles of bristles distributed around the circumference of the brush body
