Wiping device

The invention relates to a mopping device with a handle and a wringer head.

From US Pat. No. 2,873,462 a wiper device is known whose head can be wrenched out by axially pressing it together. This arrangement, however, requires a holder for the wiper head which hinders access to flat surfaces above the user, for example the top edges of the door.

209838/0106

From US Pat. No. 2,955,309 a wiping device with sponge-like, water-absorbing parts "is known which can be wrung out during rotation. However, this construction requires wiping parts that extend to the sides, so that when a floor is cleaned, a strip is left free in the middle between the wiping parts.

Furthermore, wiper devices are known from US Pat. Nos. 2,685,098 and 2,961,676 in which also the mop head consisting of a sponge can be wrenched out by squeezing it together. The use of a wringer Sponges as a mop head, however, have the disadvantage that, due to the cell structure of the mop head, on smooth floors Streaks are left behind. These constructions also require such a structure that with a small distance between There is not enough space on the underside of the furniture and the floor for the mop head. Finally, with all wipers a sponge pressed against another sponge or against an abutment with a wringable sponge head. This holds the dirt on the surface of the sponge and the mop head is ready for use again not clean.

The invention is based on the object of creating a wiper device that is versatile and lightweight is to be handled that store a large amount of water and by means of the wring arrangement together with the dirt again can deliver, and which can also be used in hard-to-reach places above the user and below furniture low ground clearance.

The object set is thereby achieved according to the invention solved that on the handle of the wiper a U-shaped bracket Defined for the head bo is that the free end of the inner Leg sits like an elongated handle that in the outer Leg a wring axis is arranged, which runs through the base of the U-shaped bracket that on the Wringaohse one Kur "at" is attached, and that means to releasable attachment of the mop head are provided on the outer leg in such a way that one end of the mop head is held and the other The end can be twisted by operating the crank on the wring axis relative to the held end.

The invention enables the design of the wiper device with the Wxing arrangement as a unit, so that none additional auxiliary equipment is required. The entire wiper device can be manufactured as a unit with a low weight, so that the user can even clean a large floor area not tired.

In a further embodiment of the invention, the mixing head can either be fixedly or pivotably attached to the wiping device so that versatile use is made possible.

According to a further feature of the invention, the mop head consists of an approximately rectangular, τ? wrapped in cloth Sponge. This has the advantage that strips, as they are only made of a sponge or another porous Existing mop head material left on smooth floors be avoided. This makes it possible to also use glass surfaces, marble floors, polished wooden floors and the like to clean properly with the wiper device according to the invention. By using cloth, however, you can also create large

209836/0106

Transfer amounts of water to the sponge. If the mop head is immersed in a bucket for unwinding or, conversely, the cloth helps to absorb large amounts of moisture from a floor. An essential advantage of using a sponge covered with a cloth is that the mop head can be cleaned in conventional washing machines without being damaged, which was previously not possible , and that the sponge can be wrung out more frequently without causing damage take, so that the service life of the mop head is significantly increased.

In a practical embodiment of the invention, the mop head is capable of more than half a liter of water take up, whereby by means of the wring arrangement more than 90 ^ of the absorbed amount of water can be released again.

The wiping device shown in FIG. 1 10 includes a head 20 attached to a bracket 12. The normal positions of the stem 11 in relation on the flat surfaces of the head 20 are shown in Fig. 1 at an angle. By attaching the head 20 in a In another position on the holder 12, however, a perpendicular relationship to the handle according to FIG. 2 can also be achieved. the Advantages of these two fastening options are illustrated in FIGS. In Fig. 3 it can be seen that the head the wiper device through its bracket-like bracket in relation to the removable handle 11 also under pieces of furniture like bed or sofa. If the head of the mopping device and .the handle according to the dashed lines run parallel in Fig. 1, the handle 11 can be an insert of the head 20 also under furniture, under which only a small amount of space is available.

An essential advantage and a special feature of the wiping device 10 is the offset between the handle and the free end of the head 20. If the head 20 is arranged perpendicular to the stem 11, with the inventive Device can easily be cleaned the upper edge of a door 22 as shown in FIG. You can also use the rectangular head Easily clean difficult-to-access and high-lying areas of a household, for example the top of valances, pipes and heating lines. In offices, too, high-lying Places like the frame 24 in Fig. 4 can be easily cleaned. The window frames of the relaxation rooms on the ground floor are often above head height, but they can with the invention Wiper device 10 as light as the top edge

20S836 / Q10B

the door 22 can be cleaned. The same goes for the top of picture frames and numerous lighting fixtures.

In the case of the usual wiping devices equipped with a sponge, the sponge is mostly on a stiffening material attached, which in turn sits on the head of the wiper device · Thus, the one surface of the wiper device determined by the holder of the head, so that the floor or a flat surface only meets a surface of the Head can come into engagement. In the wiper device according to the invention on the other hand, all four surfaces of the rectangular head 20 can be used to carry out various cleaning work. The wiping device facilitates thus right- and left-handed use as well as the Access to places previously inaccessible for a manually operated wiper device. The wiper device can also be longer used and a larger area cleaned with it before the head 20 must be cleaned.

To facilitate cleaning of the head 20 is this is designed so that it can be easily removed and then put in a normal household washing machine along with other items of clothing can be plugged. After washing it is then ready to be used again. In the known wiping devices Such cleaning is not possible with a sponge because the reinforcement material is destroyed during washing. Furthermore is subject to the exposed sponge material of rapid wear and tear and destruction in use. The head 20 of the invention The wiping device 10 consists of a sponge body 52 which is enclosed by a fabric cover 40 (FIG. 6). Through this

Training reduces wear and tear and significantly increases wiping life, while also increasing the ability the necessary capillary action for quickly sucking up water from the floor or for quickly filling the head with Water is created for wet mopping up.

The wringing process is shown schematically in FIG. The user holds the inner leg 19 of the TJ-shaped Bracket 12 fixed and rotates the wring crank 16 by means of the button 18 in the direction of rotation shown in dashed lines. By turning the wring arrangement 15 is set in rotation by the wring axis 25 (FIG. 6) which is transmitted to the outer end of the head 20, so that it is twisted according to FIG. 5 and the water is squeezed out of it. However, it has been found that some users instinctively hold the mopping device on the handle 11 while wringing it out. Therefore, the fastening part 17 is between the Bracket 12 'and the handle 11 are also designed as a handle.

Further details of the wiper device 10 in its assembled form are shown in FIG. 6. From this it can be seen that the fastening part 17 has a recess 14 for receiving the tubular handle 11. Preferably this one points tubular stem 11 has a non-circular cross-section which corresponds to the cross-section of the recess 14 to a To prevent twisting in the recess. The base 21 of the U-shaped head mount 12 is perpendicular to the axis of the inner leg 19 and to the wring axis 25 with the associated pivot bearing 28. The base 21 is designed like this? that they are tight next to each other the wring arrangement 1-5 and in particular the wring crank 16 can accommodate. The handle 18 of the wring crank is

shown in its retracted locked position in which he can be set at one end of the inner leg 19. The wring crank 16 press-fits the hexagonal end 46 of the wring axle 25 in a hexagonal pocket 56 in a hub the wringer crank. The wring axle 25 is rotatably mounted in a pivot bearing of the holder 12. In the storage 28 is a Bore 29 provided for rotatable engagement with the wring axis 25 to manufacture. In addition, anchor lugs 30 are provided opposite one another on the pivot bearing 28, the purpose of which is based on the Pig. 10 will be explained.

According to FIG. 6, the head 20 of the wiper device is provided at one end with an armature coil 31, which is connected to the rotary bearing 28 for the wring axle and the anchor lugs 30 comes into engagement. At the other end, a wrapping coil 36 is releasably engaged the locking device 35, which is attached to the free or outer end of the wring shaft 25. As explained in more detail below is, the head 20 can be attached to the holder 12 in two different positions according to FIG. 7. These positions hang from the way in which the armature coil 31, the wrapping coil 36 of the head 20 and the fixed elements on the pivot bearing 28 and of the latching device 35 are in engagement with one another.

From 3? Ig. 8 and 9 it can be seen that the inside of the armature coil 31 in each case opposite pivot slots 32 and Pest slots 34- are provided. According to Pig. 6, several locking teeth 33 are provided which form the cloth cover of the mop head by means of the armature coil clamp 61 and the wrapping coil clamp set in their place. Two collars 37 for fixing the cloth are at a distance from one another next to the locking teeth 33 "

209836/01 Q.ß

2U8799

According to Pig. 9 , the wrapping spool 36 has pivot slots 38 and plague slots 39 which are to be brought into engagement with the locking device, as will be explained below.

According to Pig. 22 to 25, the latching device consists of a latching head 43 with a contactor 44 in the middle part, into which a slightly undercut collar 47 (Pig. 6) on the inner end part of the wrapping coil 36 engages. The latching engagement of the latching head 43 with the collar 47 of the wrapping coil 36 secures the head of the wiper device in the longitudinal direction on the wringing axis 25 the slot 44 in the locking head 43 are offset by 90 °. A bore 59 is provided in the latch for receiving the free end of the wring shaft 25 and the hexagonal end is in Pig. 6 award. The hexagonal end 45 is in a clamping engagement with the bore 59 so that the wringing action of the wringing axis 25 is transmitted via the bevel 53 of the locking head 43 to the wringing coil 36 and the head of the wiper device according to Pig. 5 is wounded.

To improve the puncture capability of the locking device 25, this is provided with a spacer body 80 which extends up to the pivot bearing 28 (see Pig. 6). As a result, the hexagonal Wringaohse 25, which is made of metal, is stands entirely through an outer tubular plastic assembly shielded. When the metal axle is plated, the plating resists the corrosive effects of Detergents. However, if the plating becomes scratchy or breaks, the corrosion will occur on such exposed studs

209836/0 105

2U8799

accelerated. Complete encapsulation significantly reduces the likelihood of scratches or breaks in the flattening , which increases the service life of the product.

An additional advantage that is achieved by using the spacer body 80 is the additional support of the wring axis 25 and the aid in aligning the mop head 20 when it is attached to the mopping device 10. The additional support cancels the pulling effect resulting from the plastic injection. The end of the spacer body 80 has an undercut collar 81 which overlaps with a shoulder 82 on the end of the pivot bearing 28 in engagement. The spacer body 80 is rotatably connected to the free end of the pivot bearing 28 for the wring axle. The pivot bearing 28 is extended cup-shaped at its end in the base 21. (Fig. 10 and 12), so there can be rotatably inserted dad the hub 55 of the Wringkurbel (15 and 16 Pig.). The hexagonal end 46 of the wring axle 25 is press fit into the tab 56 of the hub 55, whereby the assembly of the wring axle 25 with the head mount 12 is completed.

The spacer body 80 of the snap device 35 is provided with anchor lugs 53, which according to Pig. 6 with the anchor lugs 30 are aligned on the pivot bearing 28. When the crank 16 is in alignment with the base 21 and the Button 27 is set, the mop head 20 can be quickly snapped on and off when the armature coil and V / ring coil are aligned accordingly.

2U8799

When the mop head is raised, a choice can be made between the fixed bracket and the pivotable bracket , depending on whether the anchor lugs 53 are brought into engagement with the wide slots 38 or the narrow slots 39 of the wrapping coil. The wide slots 32 or the narrow Slots 34 in armature coil 31 which align with corresponding slots in wrapping coil 36 are also engaged. In the "preferred embodiment, which the cross-sectional views in Pig. 8 and 9 show, a pivoting movement of the head between a ten o'clock and two o'clock position can be achieved, and with the fixed arrangement in the narrow slots according to FIG off the stick 11.

In Pig. 14 to 20, the arrangement of the handle is shown at the Wringkurbel 16 18 in detail. Pure those in Pig. The rest position shown in 20 is responsible for the return spring 13. The handle * 18 consists of a shaft 23 and a button 27, which forms the main part. The axis 23 ends in a shoulder 64 for fastening a nut, and at the other end of the axis 23 an annular space 65 is provided, which is dimensioned so that the collar 68 located on the crank 16 (see Figures 14 and 15) fits in. In the assembled state, the axis 23 runs through the crank 16. For this purpose, a bore 69 is provided on the crank 16, into which the axis 23 is inserted and then held in place by means of a peder which has one end at a cutout 70 the crank 1.6 and rests with its other end on the fastening nut 66, which is seated in a press fit on the shoulder 64. The peder 13 pulls the button 27 on the crank 16 * from Pig. 6 it can be seen that

• j ι a

2U8799

that the spring 13 and the axis 23 in a bore 71 of the head support 12 engage · For the operation detects the user operates the button 27, pulls it from the hole 71 out and then rotates the crank assembly to the water, "us the mop head 20

to wring out. ·

To reduce the weight without at the same time weakening the strength, both the crank and the base 21 of the head mount 12 are provided with a grid 74 or 78 (see in particular I ¹ Ig. 12 and 16). In FIG. 13 it can also be seen that the fastening part 17t, which serves as a handle for the operator, has an oval cross-section. The inner leg 19 serving as a handle (see Pig. 10 and 11) also has an oval shape, see above that it lies comfortably and securely in the hand of the operator during the wringing process.

The spacing and dimensioning of the individual parts is determined by their functional interaction. In FIG. 1 it can be seen, for example, that the wiping head 20 is shortened when it is wringed out. Therefore, the armature coil 32 must be mounted on the pivot bearing 28 in a longitudinally displaceable manner, but must be secured against rotation. If the pivot bearing 28 becomes too long, manufacture becomes difficult and the strength is reduced. Taking all these factors into account, including the spacing of the wring axle collar and the length of the anchor lugs, the junction between the rotary ger and the spacer 80 (as shown in FIG. 26) is approximately one-third to one-half the distance between the base 21 and the latching button 43 of the latching device 35.
