Description

The invention relates to a collecting device for resulting in a cleaning of facades cleaning fluid and a device with such a collecting device.

From the DE 40 29 757 A1 is a collecting device known for cleaning fluid, which is obtained during the cleaning of building facades. In this case, foils are designed between the building wall and horizontal scaffolding poles to form a collecting tray.

Furthermore, a collecting mat used by the applicant is known, one longitudinal edge of which is bent open and applied to the building facade, and whose opposite longitudinal edge is bent to a guide surface by means of clamps arranged on the outside. Furthermore, in this device a Flachsaugmatte used to suck the resulting liquid. A description of this collection mat can be found in the utility model AT 15 000 U2 , which is incorporated by reference in its entirety in the present application.

Against this background, it was an object of the present invention to provide a catcher for facade cleaning fluid with improved application properties.

This object is achieved by a collecting device with the features of claim 1 or of claim 6 and one by a device according to claim 8. Advantageous embodiments are contained in the subclaims.

The collecting device according to the invention for collecting cleaning liquid accumulating during the cleaning of facades contains a collecting mat as an essential element. The term "mat" indicates that the collection mat is typically a flat, flexible, sheet or strip-shaped element with two opposite longitudinal edges, the mat being impermeable to the cleaning liquid to be collected. The one longitudinal edge of the collecting mat is bent or bent to bear on a facade, while the other longitudinal edge is bent or bended to a guide surface for collected cleaning liquid. In use, the collecting mat thus forms a channel that catches at the foot of a building wall from the wall down flowing cleaning fluid.

According to a first aspect of the present invention, the collecting device described above is characterized in that it comprises a traction means which can exert an inwardly directed (i.e., towards the center of the mat) traction on the guide surface. By this tensile force, the second longitudinal edge of the collecting mat can thus be bent up to the guide surface.

Opposite that from the AT 15 000 U2 known bending of the guide surface with the help of externally applied brackets, the use of the traction means has various advantages. This eliminates interfering outwardly projecting elements (brackets) and a strong buckling load of the collecting mat. Furthermore, the traction means may be constructed of corrosion resistant materials, while staples generally must contain steel springs which will rust over time.

Typically, a plurality of traction means are distributed along the longitudinal extent of the collecting mat at suitable intervals, in order to deflect the guide surface uniformly and reliably.

For the concrete training of the traction means there are various possibilities. In particular, the traction means may comprise a flexible cable, a flexible band, a rod and / or a chain.

There are also various possibilities for connecting the traction means to the collecting mat. For example, a traction device can wrap around the entire collecting mat as an annular band or rope and thus bend to a gutter, without being firmly connected to the collecting mat at a certain point.

According to another embodiment, at least one end of the traction means is connected to the collecting mat or a point of the collecting mat (tensile strength). This connection can be permanently formed, e.g. by gluing, by welding, by knots, by sewing or the like. Alternatively, the connection can also be reversible, so that the traction means can be connected by a user in a simple manner (typically without tools) to the collection mat or can be detached again therefrom. By loosening the traction means of the collecting mat can be taken care of relaxation, so that the collecting mat take a flat shape and can be easily transported. Only when the releasable end of the traction means is connected to the point provided for this purpose the collecting mat, it comes to the exercise of traction and thus to bending the guide surface.

Typically, the traction means is connected at both ends to the collecting mat (detachable or rigid). One end is usually with the guide surface and the other end away from it fastened, preferably with a central part of the collecting mat.

In an optional embodiment of the invention, both ends of the pulling means are releasably connected to the collecting mat. In another embodiment, one end of the traction means is releasable and the other permanently connected to the collecting mat. An advantage of the second embodiment is that the traction means can not be accidentally lost.

In a further embodiment, both ends of the traction means can be firmly connected to the collecting mat. In the simplest case, then the collecting mat will be permanently in a bent-up state of the guide surface. Alternatively, however, such a traction means may also be variable in length, for example in the manner of a belt and / or forming a loop, so that the collection mat can be changed between a more or less flat and a bent state by setting a corresponding length. Furthermore, the traction means may also consist of at least two parts which can be connected to each other, wherein the non-free ends of these parts are firmly connected to the collecting mat. The free ends can then be connected to one another, for example, by means of Velcro fasteners, hooks and eyes, a knot or the like, so that the guide surface can easily be bent up by making this connection.

The detachable connection of one end of the traction device with the collecting mat can be produced, for example, via a hook and loop fastener, whereby corresponding complementary components of the hook-and-loop fastener are arranged on the associated end of the traction device on the one hand and on the intended attachment point of the collecting mat on the other hand.

In another embodiment of the detachable connection, the traction means can be connected via a button with the collecting mat. This may, for example, be a push button of the type known from the prior art. Further, the knob may also be formed by a thickening (e.g., bullet, disk, or rod) at the end of the traction means which is to be passed through an associated slot or hole in the trapping mat. Of course, a button on the collecting mat and the slot or the hole can be provided on the traction means vice versa.

According to a second aspect, the invention relates to a collecting device for collecting cleaning liquid accumulating during the cleaning of facades with a collecting mat whose one longitudinal edge is bent or bent to rest against a facade, while the other longitudinal edge is bent or bent to form a guide surface for collected cleaning liquid ,

The collecting device is characterized in that the collecting mat has at least in places an abrasion-resistant surface. In particular, the outer surface in use may be abrasion-resistant or the entire surface of the collecting mat. Furthermore, not only the surface but the entire collecting mat can be abrasion-resistant throughout.

Known collecting mats consist of a black rubber material, which proves to be in practice not tamperproof. Therefore, it may happen that after use of the collecting mat on the ground or on a facade contamination by abraded material occur. These problems are avoided by the collecting mat has an at least locally abrasion resistant surface as described above.

The collecting device according to the second aspect of the invention may in particular also comprise the features according to the first aspect, i. a traction means by which an inwardly directed tensile force can be exerted on the guide surface. Explanations given for the collecting device according to the first aspect apply mutatis mutandis to the receiving device according to the second aspect and vice versa.

The surface of the collecting mat may consist in the abrasion-resistant region in particular of one of the following materials or contain such: styrene-butadiene rubber (SBR), chloroprene rubber (CR), nitrile rubber (NBR), and / or materials with at least as high abrasion resistance as the examples mentioned ,

Furthermore, the abrasion resistance can also be achieved by packing a conventional mat in a wrap, e.g. a plastic bag.
