Description

GLASS CLEANING DEVICE WITH A WIPER RUBBER

The invention relates to a glass cleaning device from a wiper rail with a wiper blade and an associated Nachschneidevorrichtung according to the preamble of the main claim.

Known wiper rails, as described for example in DE 26 42 579 A1 or DE 1 1 53 866 B, consist of a base rail with a receiving groove for a wiper blade and have a connection piece for a handle and the handle connected thereto.

The known wiper rubbers are substantially strip-shaped, with a rectangular cross-section and a bead-shaped edge region of a narrow side, whereas where _; another narrow side has two sharp edge edges designed as functional edges, so that a wiper blade inserted into a wiper rail can be pulled out of the wiper rail and turned back after wear of the first functional edge, whereupon the second functional edge can be used up to its final wear. Then the wiper rubber has to be replaced by a new one and the old one must be disposed of.

A disadvantage of this known wiper rail is the high consumption of wiper rubbers, in commercial use about one to two per week, since they have only two usable functional edges and each edge has only a certain life as a function of the cleaned surface and its degree of contamination. This is on the one hand very cost-intensive and on the other hand little environmentally friendly.

Another, known from DD 213 833 known window wiper, has a reversible and / or adjustable wiper rubber, but said font provides no reworkable technical teaching this. Another disadvantage of all known window wipers is their rigid design, which allows no individual or adapted to a work situation setting. The object of the invention is to provide a glass cleaning device available, which is considerably more economical than the known glass cleaning devices and which leads to a much lower environmental impact. Furthermore, it should be customizable or adaptable to changing work situations. The solution to this problem results in conjunction with the preamble features according to the invention from the features of the characterizing part of the main claim and those of the independent claims.

Characterized in that the wiper rail of the glass cleaning device consists of a base rail of a first hollow profile with a passage gap for the wiper rubber and a designed as a second hollow profile with a further outlet gap for the wiper rubber movable rail, and the movable rail in the direction of the passage gap of the first Hollow profiles is held displaceably parallel in the base rail, the wiper rubber can be different far out of the base rail. This construction makes it possible in an advantageous manner, in particular with the aid of a regrooving device, to be able to separate a narrow strip of material from the flat face of the winding rubber, whereby new sharp longitudinal edges are provided as functional edges and the wiper blade again in an optimized exit length from the base rail can be adjusted according to individual preferences or adapted to a work situation.

This innovative solution already a significant cost savings for the consumer is achieved and achieved a much better resource utilization.

Because a retaining rail designed as a third hollow profile with a passage gap for the wiper rubber is arranged in the rail, a simplified handling of the wiper rail when replacing a wiper rubber can advantageously be achieved since initially one longitudinal side of a wiper rubber penetrates into the third hollow profile is introduced, which may for example consist of plastic and may have a certain elasticity, wherein the passage gap in the unobstructed free state of the retaining rail may be slightly wider than the measure of the thickness of the wiper blade, so that greatly facilitates insertion of the wiper blade into the retaining rail becomes.

Further advantageous embodiments of the subject of the invention will become apparent with and in combination from the following subclaims. It is furthermore particularly advantageous if the retaining rail is designed as a clamping device for the wiper rubber and the passage gap of the retaining rail in the inserted state in the movable rail has a width dimension which is slightly smaller than the thickness of the wiper blade, so that here via an elastic deformation the wiper rubber a firm clamping fit is generated without mounting holes or locking lugs on the wiper rubber or in the retaining rail should be provided.

For the function of the glass cleaning device, it is also advantageous that between the base rail and rail elastic spring elements can be used, which hold the rail biased in the direction of the passage gap of the base rail, wherein a. Adjustment device is provided which holds the rail in relation to the bottom of the base rail at an adjustable distance. Accordingly, the exit length of the wiper rubber from the passage gap of the hollow profile can be adjusted continuously or in individual steps by means of the adjustment device.

In the middle, rearwardly directed region of the rail for this purpose advantageously a connecting means is provided with a likewise rearwardly directed adjusting means and in the parallel region of the base rail, a passage opening for the connecting means, wherein in the connecting piece for a handle or in a handle, a device with a corresponding Is arranged receptacle for the adjusting means with which the movable rail in different positions in the base rail is locked and these positions are freely adjustable by a cleaning person via simple actuating means, so that not only a single fixed length adjustment of a wiper rubber is present, but the Wiper rail can also be adjusted to the preferences of different cleaning personnel. The adjusting means for this purpose is advantageously designed as a threaded pin and the receptacle as a thumbscrew, which is mounted in a recess in the connector and protrudes for adjustability on the contour, so that at any time easy accessibility and usability is guaranteed. According to a particularly preferred embodiment of the invention, the base rail can be rotated by 180 ° reversed inserted into the connector, so that the glass cleaning device can also be used as a pusher. For this purpose, the base rail has detents in the longitudinal and transverse direction outside in the region of the connecting piece and the detent corresponding to the connecting piece. So that the base rail in the connection piece in the longitudinal and transverse direction and in the vertical direction to the connection piece can be easily and easily locked. This also makes it possible to clean difficult-to-reach panes, which would be possible with the known pullers only with the aid of expensive technical aids

In a particularly advantageous embodiment of the invention, a rotary joint is arranged between the connection piece and the handle, so that the angle between either either can be fixed or it is further an elastic spring element such as a steel spring interposed so that the connection piece in principle at an angle is kept angled and can only be pivoted from a certain application of force against the elastic spring force around the hinge around in a fully stretched position, which is advantageous in certain situations, such as large or deep slices. If this _^ function off, or turned on, a fixing lever can be connected to the connecting piece advantageously be arranged, which has a latching nose which engages in a notch in the base rail and so the rotation about the pivot when necessary locks or releases.

According to a particularly preferred embodiment of the invention, the wiper rubber is formed as a flat strip with a completely rectangular cross section, so that initially all four longitudinal edges can be used as functional edges. This also makes it possible to use the end face of the wiper rubber, which is usually held in the wiper rail, thereby resulting in further cost savings and a significant saving of resources. Narrow strips of material can also be cut off from this second end face of the wiper blade, so that the new frontal longitudinal edges again form functional edges and, for example, can be used 22 times as often as a simple wiper blade of a known type in a wiper blade that can be trimmed 10 times.

According to a particularly preferred embodiment of the invention, the glass cleaning device is associated with a regrooving device for the wiper rubber, in which a cutting device for producing a thin edge portion of the wiper rubber is arranged, as well as a propulsion device for the wiper rubber along the cutting device. This Nachschneideeinrichtung allows a clean straight-line section of the front side of the wiper blade, whereby optimal functional edges can be generated. Such Nachschneideeinrichtung may have a propulsion device which is operated manually or electrically and is additionally provided in the latter case with an electrical voltage source.

The regrooving device advantageously has a fixed or rotating cutting blade and a guide of the wiper rubber on rollers and / or along a longitudinal guide with surfaces with very little friction, which are provided for example with PTFE or other reibvermindemden surfaces, so that the wiper rubber during the Nachschneidens not different elastic Deformations is exposed and sets an optimal work result.

According to a particularly preferred embodiment of the invention, the second and the third hollow profile are combined to form a common profile, so that the handling of the glass cleaning device is further simplified. Furthermore. can a washer associated with the system with one of the

Provided in the connection ^' piece (1 1, 1 1 1) can be latched so that the device can be used even more universal and difficult to access glass surfaces are first lathered before pulling or pushing off easily can.

The other side leg is slightly more inwardly bent in a first version of the wiper rail 33 and thus forms a guide surface 14 for the wiper rubber 4. In a second version of the wiper rail 133, the other leg is straight, with each upper end a passage gap. 5 105 for the wiper rubber 4. Within the still U-shaped region of the hollow profile of the base rail 1, 101, a movable rail 2, 102 designed as a second, approximately square hollow profile is used, which is movable in parallel along the parallel side limbs of the hollow profile of the base rail 1, 101. The movable rail 2, 102 likewise has an outlet gap 6, 106 for the wiper rubber 4.

In this second hollow profile of the movable rail 2, 102 is a third hollow profile as a support rail 3; 103 used, which also with a passage gap 7; 107 is provided, wherein this in the movable rail 2; 102 pushed state, B. width dimension has, which is slightly smaller than the thickness of the wiper blade rubber 4, so that this is clamped in the installed state of the support rail 3, 103 in the movable rail 2, 102 there. The position of the movable rail 2, 102 in relation to the base rail 1, 101 along an adjustment range 34, 134 can be varied as desired via the adjusting means 9, 109. Between the movable rail 2, 102 and the inside of the base rail 1, 101 elastic spring elements 10, 10 are arranged, which keep the movable rail 2, 102 biased in the direction of the passage gap 5, 105 of the base rail 1, 101. In the assembled state, a connecting piece 8, 108 with a likewise rearwardly extending adjusting means 9, 109 with a screw thread is arranged on the rear side of the movable rail 2, 102, which also extends through a passage opening 15 in the base rail 1; extends in a connection 1 1; 1 1 1 in a recess 17; 1 17 mounted receptacle 32, which is designed as a knurled nut and which partially extends over the contour of the connecting piece 1 1; 1 1 1, so that the movable rail 2; 101 and can be moved in the opposite direction to the connecting web of the U-shaped hollow profile or the base of the base rail 1, 101 and can be adjusted in different positions to the base rail 1, 101, whereby the wiper rubber 4 differs from the base rail 1 to a different extent ; 101 can lead out or after the separation of a front edge region of the flat front side again optimized for the glass cleaning blade length of the wiper blade 4 can be adjusted.

The wiper blade 4 is designed as a flat strip with a rectangular cross-section in unloaded free state, so that four sharp longitudinal edges 12 can be used as functional edges, with the outermost longitudinal edge 12 acting as the functional edge to be used currently. To change the functional edges, the retaining rail 3, 103 can be pulled out of the movable rail 2, 102, whereupon the clamping of the wiper rubber 4 due to the elasticity of the retaining rail 3; 103 is reversed and the wiper blade 4 turned or completely inverted again inserted into the support rail 3, 103 and this can be inserted into the movable rail 2, 102.

The connector 1 1 of the first version of the wiper rail 33 further includes two brackets 24, with which it surrounds the base rail 1 partially and, as shown in Figures 2 to 4, the contoured base rail 1 krafteng and positively klengmt. Between the connecting piece 1 1, 1 1 1 and the handle 16, 1 16 a pivot 18, 1 18 is arranged, whereby the angle between the two is variable.
