Wiper device with split wiper head

Addition to patent 584

Patented in the German Empire on January 15, 1933 The main patent started on July 10, 1931.

The mopping device described in the main patent 584 481 consists of a split, with a spongy coating provided with a wiper head, on which the device handle by means of a crosshead by approximately i8o ° is mounted pivotably and its two parts each so on <lem crosshead are articulated and pivotable by a traction means that attached to them Lining parts are pressed against one another can to express the liquid.

This mopping device is improved and further developed by the invention. the Invention is that for "connection of each wiper head part with the crosshead a two-way pivoting double joint is used, which is a special one Articulated connection between transverse

ao makes the main and device handle unnecessary and in turn the pivoting of the handle by approximately i8o ° enables.

This has the advantage that the pivot axis for the handle is as close as possible placed on the surface of the mop head and thus the floor also under very low furniture can be cleaned. The traction means for pivoting the According to the invention, the wiper head part consists of a swivel joint with the device handle Rod that is hinged to both wiper head parts and the adjustment of this Causes parts by a longitudinal movement imparted to it by a worm gear guide or the like, whereby the wiper covering can be pressed together very strongly without touching it.

In the drawing, for example, an embodiment of the mopping device is shown, namely show:

The Wischerkopfbelag'ι is attached to two plates 3, 3 ¹ , which are hinged by hinges 12, 12 ¹ - on opposite sides of a metal plate 5 (Fig. 5, 6). Bearing blocks 4, 4 * are attached to the plate, in which the lower end of a rod provided with a slot 11 is mounted on a pin 10 so that it can pivot through 180 ° transversely to the longitudinal direction of the covering 1 (Fig. &, 9) '. The rod 6 protrudes into the tubular device handle 7 (Fig. 3) and can be moved up and down in this in the longitudinal direction.

A fixedly attached to the lower end of Gearätetielsy crosshead is provided with two arms 8,8 ^1, the cross-by on pins 14, 14 ¹ 13.13 handlebar ¹ according to a double joint 24, 24 ¹ in the Böekett'9, 9 ¹ the Flutter 3, 3 ^{1 are} steered. The joints ^{24, 24 1} lie in an axial line with the heavy-duty pin 10 of the rod 6. The double ^{joints 24, 24 1} allow the link 13, 13 * to oscillate on their pin ^{14, 14 1} (Fig. 14, 15), but also .Also, if the plates 3,3 in ¹ of i the position of use that are available covering 1 in \ a plane (Figure 1,. 5), and, thus, the pivot pin of the χ 'joints 24,24 ¹ in the _same; Axial line with the pivot pin 10 stand, i a pivoting of the handle about this Achslaaie, as shown in Fig. 10, 11, I3j. The group consisting of ^JJ-1 iron arms 8,8 project beyond the pins 14,14 ^ and assume their .Between -Schenkeln the handlebars 13, 13 ¹ EO sxa that .these gegeneinander- "can only be swung inwardly and against · ; Bottom webs of the U-irons & ^{,. 8 1.} Abut when the two plates 3, .3 ¹ lie in one and the same plane. To determine the position of the plates 3, 3 ¹ ; - 'lags ι to secure, project over the .an attached to the hinge plate 5 Lag.erbo.cke 4,4 * with their edges cd the two plates 3,3 ¹ (Fig. ξ, £, 14, Ij) ₃ so that these cannot be swung up beyond this level.

At the upper end of the rod 6, which can slide in the handle 9, a handle extension can be rotated loosely (Fig. 4) 20 attached, into which a pin ζ 8 is screwed from the outside. This pen 18 slides in a partial -as. Worm gear trained slot guide 15, 16 in Stem tube 7 and is through the wall of a ■ pipe piece slidably slid onto the tube 7 19 led. A catch 17 is provided at the lower end of the slot 15.

If the device handle 7 looks perpendicular to the device head, the pin 18 takes the from the Fig. 5 position in the slot 15, and then the rod 6 is raised as far as can be seen from Fig. If you want to set the handle in the most common inclination of about 45 ° (Fig. 11), then after swiveling the handle .das pipe section 19 is pushed down a little and rotated, whereby the pin 18 enters the detent 17. By pushing the pipe section 19 downwards, the rod 6 is pushed down slightly, whereby its beveled lower end enters the recess 21 of the hinge plate 5 (Fig. 9) and is supported against the edge of this recess 21. This support prevents the rod 6 from moving towards the wiper head. In order to secure this adjustment of the device the stem .to wiper head with setting of the handle in the most geääräuehlieibe Winkelsielking of about 45 ° even more, of a side ■ is leg of each arm 8, 8 ¹ extended so far that its edge from against the Bucks 9.9 * can hit (Fig. 7). The edge ^ -fe prevents .then however / that the handle can be folded completely horizontally on one side of the mop head. The horizontal position of the handle to the mop head is possible on its other side (Fig. 7,13), so that when the handle is in a flat horizontal position, the mopping device can even get under very low furniture.

. If the coating 1 is to be expressed, the pin i; 8, after it has been moved out of the detent 17 by a small rotation of the pipe section 19, is moved upwards by shifting the pipe section 19 in the slot 15, the rod 6 being the pin 10 and thus also the hinge plate 5 upwards. Since the stem 7 and the crosshead 8, 8 ¹ do not follow this movement, but the plates 3, 3 ¹ endeavor to follow this movement through their hinged ligament connection 12, 12 ¹ with the plate 5, the plates 3, 3 ¹ by virtue of the articulation% 24, 13, 14 gegeneinand'ergeschwenkt with the arms 8, 8 ¹ in the manner shown in the Fig. 14 example. This pivoting movement could be repeated several times in or above a water bucket while dipping the wiper head several times into the water.
.. Should the water from the Belae 1 drain

are pressed, the pipe section 19 is pushed as far up as it is through the the straight slot part 15 guiding the pin 18 is possible. The pipe section 19

, 5 rotated, whereby the pin 18 is wound in your worm or screw thread slot 16 upwards. As a result, the extension 20 carrying the pin 18 and thus also the rod 6, which is loosely rotatably connected to it, with the plates 3, 3 ¹ is pulled more and more upwards, which, by virtue of the articulated connection 9, 24, 13, 14 with the arms 8, 8 ¹ the plates 3, 3 ¹ are brought closer and closer to each other and the lining halves are pressed together (Fig. 15). By turning back the pipe section 19 and pushing it downwards, the wiper head returns to the position of use according to FIG. 1.
