This underside 64 of the stripping device 32 is with a Bulge 134 (FIGS. 6 and 9) in a front of the engagement part 60 provided longitudinal section of the handle 36. The bulge 134 in turn forms a longitudinal groove 136 with an inverted U-profile, from the bottom 137 parallel to Longitudinal axis of the handle 36 and at a distance from each other four locking ribs 138, 140, 142, 144 vertically downwards protrude (Fig. 9). These four locking ribs 138, 140, 142, 144 of the stripping device 32 serve to stiffen the Wiper handle 36 and form three locking grooves 146, 148, 150 same width, slightly larger than the width of the three locking ribs 112, 114, 116 of the cleaning device 30 are measured. As a result, the three locking ribs 112, 114, 116 of the cleaning device 30 into the three locking grooves 146, 148, 150 of the stripping device 32 engage. At the same time, the four locking ribs 138, 140, 142, 144 engage of the stripper 32 in the four locking grooves 118, 120, 122, 124 of the cleaning device 30 when both devices 30, 32 combined by plugging them into each other to form the compact handheld device 20. It it can be seen that the locking grooves described above and locking ribs the cost of materials and thus that Reduce weight for the two devices 30, 32 at the same time but in addition to the mentioned stiffening stable alignment and connection of devices 30, 32 via ensure their entire length. Of course you can e.g. B. depending on the selected overall dimensions of the handheld device 20 the number of locking ribs and locking grooves vary. Furthermore, the shape of the interlocking can optionally Modified elements of both devices 30, 32 become.

4 and 6, the two middle extend Locking ribs 140, 142 of the stripping device 32 up to the front End face 74 of the engagement part 60. Here are lower Longitudinal edges 152, 154 of these two central locking ribs 140, 142 on a rear length section that is about three Fourth corresponds to the length of these locking ribs 140, 142, essentially parallel to a surface line on the underside 156 of the conical engagement part 60 arranged (FIG. 6), but in height compared to the underside of the generatrix 156 of the engaging part 60 is set upwards. Here the height of the locking ribs 140, 142 decreases increasingly above the bottom of the reverse U-shaped longitudinal groove 136 in Scraper handle 36 up to the level of the division plane T determining underside 64 of the handle 36.

The two outside locking ribs 138 and 144 of the Stripper 32 are shorter and rear only extend to one at their rear end Groove 158 of the longitudinal groove 104 (Fig. 4) into which the front end 74 merges, as shown in FIG. 6, wherein their rear end edges 160, 162 down and forward are beveled. Lower longitudinal edges 164, 166 of these outer locking ribs 138, 144 run on a smaller Height than the lower longitudinal edges 152, 154 of the middle Pair of locking ribs 140, 142, but parallel to these a back half of its length. Are accordingly earlier the two outer locking ribs 138, 144 in the amount of Bottom of the wiper head 25 angled and ending, like the two middle locking ribs 140, 142, in one front, fluted end face 168 (Fig. 4) of the reverse U-shaped longitudinal groove 104 of the stripping device 32.

It should be emphasized that, according to FIG. 3, the rear end the middle locking rib 114 of the cleaning device 30 backwards over the rear ends of the neighboring ones Locking ribs 112, 116 protrude and, as mentioned, as front end face 70 of the receiving part 58 in the cleaning device 30 a stop for the front end face 74 of the Engagement part 60 of the stripper 32 in Fig. 4 forms. As a result, the cleaning device 30 and the stripper 32 as a combined handheld device 20 fixed, but detachable connected to each other when the locking ribs and locking grooves of both devices 30, 32 fully interlock and are locked by the locking bolt 86. It is thus understandable that the locking ribs and the locking grooves the cleaning device 30 and the stripping device 32 locking elements and form their receiving openings. If necessary can of course such locking elements also in shape at least one bolt and one provided at least one receiving opening in the devices 30, 32 be present because only the axial and lateral Establishing both devices is essential if they are are assembled together to form the handheld device 20. Out for this reason, the receiving part 58 and the Engagement part 60 also designed as a latching connection be by which the two devices 30, 32 held together because, for this purpose, only those in the compound State of the two devices 30, 32 opposite End faces or long sides of the receiving part 58 and the engaging part 60 with corresponding ones Locking elements are to be equipped.

The above description of the handheld device 20 clarifies that this z. B. can be used as a window wiper can, in which the scraper 24 as a water scraper and the cleaning member 22 serve as a window cleaner.

Both devices can use the conical locking bolt 86 to the single handheld device 20 connected and by unscrewing the locking bolt 86 again in two separate devices 30, 32 be separated. Since the locking bolt 86 on the rear End is equipped with the internal thread or the like. Can into this an extension and / or a joint if necessary be screwed in. The locking bolt 86 can both in the stripper 32 or in the cleaning device 30 alone, as well as in that composed of these devices 30, 32 Handheld device 20 can be screwed in. Because with that assembled handheld device 20 the wiper lip 54 and the cleaning pad 43 on the underside of the handheld device 20 are located in one operation cleaning surface, e.g. B. a window, washed and dried become. The cleaning liquid that occurs when wiping, Like water, the cleaning pad 43 resumed.

15 to 26 is a fourth, particularly preferred Embodiment of a handheld device 400 according to the invention illustrates the more detachable connection options a cleaning device 401 with a scraper 402 contains. 15 and 16 is a handle 403 of the handheld device 400 from an outer, tubular Handle 404 of the cleaning device 401 together, the 20 and 24 forward end 405 forward and downward increasingly widened as a cleaning head 406, with a transversely extending wiper plate 407 unitary formed and at the rear end with an opening 431 is provided.

15 and 16 is in the handle 404 of the cleaning device 401 a tubular handle 408 of the Scraper 402 telescopically inserted coaxially. The Wiper 402 has a wiper head 409, the tubular scraper bracket 410 in turn a guide rail 411 for a wiper lip 412. Here grips the guide rail 411 with a central spring tongue 413 in a front, middle recess 414 of the Scraper bracket 410 flexible (Fig. 16 and 22), so that the guide rail 411 with the clamped therein Wiper lip 412 is easily interchangeable.

The guide rail 411 lies in the handheld device 400 in FIG. 15 at a short distance from a front edge 415 of the wiper plate 407, the cross profile of this leading edge 415 the Radius of a trailing edge with a circular arc in cross section the guide rail 411 is adapted as shown in FIG. 24. 20, the front edge 415 of the wiper plate 407 has and 24 again a right-angled cutout 416 one to the front edge 415 of the wiper plate 407 axially recessed, parallel stop surface 417 for the Wiper holder 410 of the guide rail 411.

15 to 17 and 18 to 20 is between the outer Surface of handle 408 of stripper 402 and the inner surface of the cylindrical cavity of the handle 404 of the cleaning device 401 a locking device 418 (Fig. 17) is provided. This locking device 418 begins to take effect just before the moment that Stripper 402 its complete, as described above Insert end position in the handle 404 of the cleaning device Has reached 401. As a result, that is Scraper 402 with its scraper bracket 410 on the Stop surface 417 of the wiper plate 407 with a certain axial preload. This bias is so great dimension that even under extreme working conditions, at stronger forces on the combined handheld device 400 be exercised, the described firm, but by hand Detachable connection between the cleaning device 401 and the Scraper 402 remains intact.

17, 19 and 20, in particular, that the stop surface 417 protrude two locking cams 419, 420, whose underside 421 with one on the underside of the Wiper plate 407 attached Velcro 41 is aligned already described in more detail above with reference to FIG. 2 has been. A ramp surface that extends upwards and backwards 422 at the front end of the locking cams 419, 420 at the same time part of an upper, transverse locking rib 423, which to the rear and down to the locking rib 423 parallel locking groove 424 drops. The locking groove 424 is on the Back through the stop surface 417 of the cutout 416 limited. The height of the locking cams 419, 420 extends approximately to to half the height of the front edge 415 or stop surface 417 the wiper plate 407. Instead of the number described of two locking cams 419, 420 can of course one more or less large number of locking cams also others Shape design can be used.

17, 19 and 22 are at the bottom of the Wiper head 410 of the wiper head 409 two Locking recesses 425, 426 are provided, the locking cams 419, 420 of the cleaning device 401 corresponding dimensions exhibit. The locking recesses 425, 426 are with a provided rear boundary edge 427. This boundary edge 427 of the stripping device 402 hits during axial insertion the same in the handle 404 of the cleaning device 401 on the inclined contact surface 422 of the locking cams 419, 420 before the locking cams 419, 420 through elastic bending into the one assigned to them Snap in the recess 425, 426 and the two tools Connect 401, 402 firmly but releasably.

According to this fourth embodiment of the handheld device 400 there are several ways to get the detachable connection between the two tools 401, 402 either in Combine with one or more of the above described, detachable fastening devices, such as B. the locking device 418, between the tubular Wiper holder 410 of the wiper 402 and Wiper plate 407 of the cleaning device 401, or only alone with the help of one or more frictional or Clamp connections directly between the two mentioned Tools 401, 402 in an extremely simple manner and in essentially invisible to the user.

Such manually releasable friction connections can namely if desired, fully alone are sufficient, both tools 401, 402 are sufficiently firm, but still releasably connectable by hand.

15, 16, 18 to 20 and 22 to 24 is the fourth Embodiment of the handheld device 400 according to the invention with a first embodiment of such a frictional connection shown. This frictional connection is with Designated 433 and consists of a clamping spring-clamping groove connection, which consists of at least one clamping spring and assembles at least one associated clamping groove. In the 15, 16, 18, 19, 22 and 23 are two clamping springs 434, 435 to see, the whole with the scraper head 409 are shaped and protrude vertically from its underside. 22, the clamping springs 434, 435 are at the axially front End by means of a connecting web 436, 437 with the rear of the tubular scraper bracket 410 and connected to the underside of the wiper head 409. This Connecting webs 436, 437 are narrower and therefore more flexible than the clamp springs 434, 435 and mediate the clamp springs hence a desirable additional lateral flexibility; they have z. B. an axial length of about 2 mm and a Width of about 1.5 mm, while the width of the free, lower longitudinal edge 438, 439 of the clamping springs 434, 435 approximately Corresponds to 4 mm. 18, the clamping springs 434, 435 a cross section, the width of which is from the lower longitudinal edge 438, 439 each clamping spring 434, 435 from upwards respectively on its outside 434a, 435a except for a smaller one Width of z. B. 3 mm is reduced. This broadening each clamp spring 434, 435 preferably extends only over a lower third, e.g. B. about only 4 mm of their total height. Furthermore, form opposite side surfaces at a distance 440, 441 of the two clamping springs 434, 435 together with the underside of the scraper head curved forward and down 409 one open at the bottom and back Central longitudinal groove 442, the profile of which is that of an inverse U is similar. This the groove walls of the central longitudinal groove 442 forming side surfaces 440, 441 of the clamping springs 434, 435 close a pointed, downward opening Angle on and are parallel to the central longitudinal axis of the scraper 402 directed. The lower, free longitudinal edges 438, 439 are in a common, to the central longitudinal axis of the stripping device 402 parallel plane on a Height arranged at a distance above the recesses 425, 426 of the tubular scraper holder 410 extends.

The clamping springs 434, 435 are from the tubular Scraper holder 410 freely to the rear on one length from Z. B. about 16 mm in front and have a side view trapezoidal surface (Fig. 16). One from the bottom of the Scraper head 409 formed head wall 443 in Fig. 16 and 18 of the open, acute-angled central longitudinal groove 442 forms with a vertical, flat rear 444 the tubular scraper bracket 410 in Fig. 17, with the the front ends of the clamping springs 434, 435 are connected, an obtuse angle (Fig. 16).

16, 19, 22 and 23, the front end 432 of the Handle 408 of the stripping device 402 tapering closed and ends at a small axial distance in front of the rear end faces 445 of the clamping springs 434, 435.

18 and 20, the cleaning device 401 is at the front End of the cutout surrounding an insertion opening 463 429 in the middle of the approximately U-shaped cross section there Inner wall of the handle 404 with two clamping grooves 446, 447 Mistake. These clamping grooves 446, 447 have a dovetail-like, thus cross-section widening to the groove bottom and serve to accommodate the similar in cross section Clamping springs 434, 435 of the stripping device 402. Die Clamping grooves 446, 447 extend parallel on both sides a vertical central longitudinal plane of the cleaning device 401 and are separated by a central guide spring 448, those for approximately axial engagement in the middle, vice versa approximately U-shaped, clamping central longitudinal groove 442 of the Stripper 402 is provided. The clamping grooves 446, 447 are therefore slightly longer than the clamping springs 434, 435 sized and closed at the rear end. The two As mentioned, clamping grooves 446, 447 are undercut, such that outer groove walls 449, 450 of the clamping grooves 446, 447 with the opposite, parallel to each other Side walls of the guide spring 448 a to the groove bottom include each widening angle, but the to rear, closed end of the clamping grooves 446, 447 out is reduced. As a result, the two clamp springs 434, 435 of the stripping device 402 during the axial insertion in the clamping grooves 446, 447 increasingly against the both sides of the guide spring 448 until reaching one firm, but manually releasable friction connection (Figs. 20 and 24).

The achievement of a frictional engagement or clamping fit between Cleaning device 401 and stripping device 402 can additionally to the friction connection 433 described above, or even alone, through another frictional connection immediately between the two tools 401, 402 be provided. This frictional connection can according to FIG. 15 to 24 by a frictional connection between a front, upper end 451 of the middle guide spring 448 of the Cleaning device 401 and the forward and downward curved Head wall 443 of the wiper head 409 in the downward direction open central longitudinal groove 442 by a reinforcing Friction inhibition when inserting the guide spring 448 of the stripping device 402 reached in the cleaning device 401 become.

A particularly advantageous, immediate, so without additional Parts accessible friction connection between The two tools 401, 402 can be as follows realize as described:

20 and 24 is an axially extending, approximately cylindrical cavity 428 in the handle 404 of the cleaning device 401 with a front, upper cutout 429 provided about a third of the total length of the Handle 404 corresponds. This cutout 429 runs along a division plane T4 with respect to the wiper head 409 of the stripping device 402 in FIG. 23. A first, rear and flat section T4a of this division level T4 is from the top of handle 404 to the front end of the handset 400 obliquely forward and down to about the central longitudinal plane of the handle 404 directed and therefore closes with this one to the front End of the handle 404 opening upwards, obtuse angle. The apex of this obtuse angle forms a step 430, after which a second, front section T4b of the dividing plane T4 initially gradually and then curved more forward and downward and in the vertical stop surface 417 of the cutout 416 of the wiper plate 407 runs out.

An edge 452 of the underside of the wiper head 409 in the 17, 18, 19, 22 and 23 naturally correspond to the contour an edge 453 of the cutout 429 of the handle 404 or the top of the cleaning head 406 (Fig. 20), so that the handheld device 400 in the assembled state of Tools 401, 402 in the area of division level T4 has a smooth surface. 15 and 21 is the rear, increasingly narrow and end of the wiper head 409 shaped as a nose 455 which is round in plan view. The nose 455 is delimited by a rear face 456, in the manner of a truncated cone from the cylindrical Outside of the handle 408 of the stripping device 402 diagonally upwards and forwards to a round back Upper edge 457 of nose 455 protrudes. On both opposite Longitudinal sides is the nose 455 through in side view triangular, parallel, perpendicular Guide surfaces 458, 459 limited, of which only in Fig. 23 the right guide surface 458 can be seen. To these guide surfaces 458, 459 closes the projecting downward Edge 452 of the underside of the wiper head 409 on. In the area of the nose 455 is the top of the scraper head 16 and 21 with a finger dent 460 and several arrow-shaped gripping ribs 461, which is the cancellation of the frictional or clamping connection between the cleaning device 401 and the stripping device 402 by hand facilitate.

According to the described projecting backwards End face 456 of the nose 455 of the wiper head 409 is the edge 453 of the cutout forming the insertion opening 463 429 of the tubular handle 404 of the cleaning device 401 on its top with one in the insertion opening 463 directed, groove-like chamfer 464 provided (Fig. 24). This chamfer 464 is obliquely to the rear and down into the inside of the handle 408 of the stripper 402 directed and has a width equal to the distance of the two vertical, axially parallel guide surfaces 458, 459 in the area of the nose 455 of the wiper head 409 corresponds. As a result, the frustoconical face 456 of the nose 455 with their lateral guide surfaces 458, 459 completely into the insertion opening 463 of the tubular handle 404 of the cleaning device 401 in Area of this chamfer 464 engage and the nose 455 des Wiper head 409 is flush with the Create edge 462 of cutout 429.

To achieve the frictional connection between the scraper 402 and cleaning device 401 in the insertion end position of both devices forms an insertion opening 463 of the Cleaning device 401 surrounding, to the front and down curved edge 453 of the top 454 of the cleaning head 406 and the underside, correspondingly curved edge 452 of the wiper head 409 overrun or friction surfaces 466, 467. For this purpose, the curvature of the rear, in front of a vertex forming a step 465 lying friction surface 466 of the edge 453 of the cleaning head 406 to a height through which a frictional connection is determined with the stripper 402. Getting closer these two mentioned friction surfaces 466, 467 of the Cleaning head 406 and the wiper head 409 Reaching the insertion end position of the stripping device 402 in the cleaning device 401, one behind the scraper head 409 horizontal front section 469 of the handle 408 of the stripper 402 with its top raised so much and against a front Length section 470 on the top of the inner wall of the Handle 404 of the cleaning device 401 pressed that each reliably the desired friction or Clamp seat in the insertion end position of both tools 401, 402 is achieved.

The locking and friction connections described above can, as described, either alone or, as with the shown fourth embodiment together with one or more of the friction connections described for the two tools 401, 402 be used. When using both together Lanyards can be coordinated be that at the end of the insertion movement of the stripper the engagement of the locking device or the frictional engagement possibly by striking the stripper 402 against the cleaning device 401 for the operator is clearly noticeable.

In FIG. 22, the stripping device 402 is seen from below its hollow cylindrical handle 408 and its scraper head 409, which, like a comparison with the 20 shows the cutout 429 of the handle 404 of the cleaning device 401 completely fills in such a way that a flush, smooth surface of the Combined handheld device 400 is created. this makes possible convenient handling of both the combined handheld device 400 as well as a separate handling of only the Cleaning device 401 or only the stripping device 402, because they produce a locking or frictional connection Means are practically invisible to the user and none their handling requires disruptive design. Here can be in a rear opening of the handles 404, 408 in 23 and 24 an auxiliary device, for. B. an extension handle, be used. The opening in handle 404 is designated 431.

It is also understandable that the snap connection only could consist of locking knobs on one of the opposite surfaces are provided and with depressions interact, either the shape of the nubs correspond or, as in the case described, in ring grooves or differently shaped recesses in the opposite Snap the surface into place.

The above comments on the second, third and fourth embodiment of the handheld device 200, 300 and 400 according to the invention show that the handheld device in each case only from the associated cleaning device and stripping device exists that only by telescoping their handles until the stop of the Scraper head on the cleaning head and / or by a Form and / or frictional connection between the two devices can be combined into the handheld device, and - if this is desired - also only by an axial Separation by hand in the direction of the arrow in Fig. 11 below Overcoming that exercised by the detachable connections Resistance can be separated. About that In addition, the invention has the advantage that both handles a round or oval over its entire length Have a cross-section and therefore a particularly convenient one Handling as with separate cleaning devices and scrapers allow the surface of the Handles rib-like contoured can be a better one Convey grip and the relative, telescopic To facilitate pushing of the handles.

Finally, it should be mentioned that the rear Ends of the tubular, hollow cylindrical handles 404, 408 of the cleaning device 401 and the stripping device 402 are open and each have a frustoconical shape on the inside have tapered section 471, 472. These sections 471, 472 of the handles 404, 408 of the two Tools 401, 402 can be the same, according to form the cone angle opening on the outside. But here is the Diameter of the inner end of the conical end section 471 of the cleaning device 401 is smaller than that Diameter of its otherwise cylindrical cavity, so that an annular shoulder 473 is formed, which acts as a stop for a rear end 474 of the handle 408 of the stripper 402 can serve. On the other hand, the Inner diameter of an opening 475 in the rear end 474 of the handle 408 of the stripping device 402 smaller than the inside diameter of the inner ring shoulder 473 in the handle 404 of the cleaning device 401, so that the rear Front end 474 of the handle 408 of the stripping device 402 forms an inner ring shoulder, which is partly on the Ring shoulder 476 when both are pushed together Working tools 401, 402 are present, but via the latter protrudes radially inwards. As a result, both are conical end portions 471, 472 of the handles 404, 408 of the two tools 401, 402 in diameter against each other graded and can be immediate or indirect Inclusion of an operating rod for working with the combined handheld device 400 or working in each case only with the cleaning device 401 or only with the scraper 402 serve.
