Description

Moppirunko

The invention relates to a mop body for cleaning textiles according to the preamble of claim 1.

Nowadays, mops often have accessories attached to the mop frame to diversify floor mopping with a cleaning cloth affixed to the underside of the mop. These include e.g. places for dusting cloths on top of mop frame and water wiper edge to remove water from floor.

One of the major problems with these current so-called multifunctional mops is that the attachment of the cleaning textile to the mop body is often such that it degrades over time. Among other things, the overall muck body plate base adhesive fastening is weakened by repeated fastening and opening times between the cleaning fabric and the mop plate body, so that the Velcro fastener or, in the worst case, the entire plate body has to be replaced.

Another major disadvantage of current accessory multifunction mops is that they generally have a plurality of interlocking loose bodies, which significantly increases manufacturing costs.

Another major drawback with current multifunctional mops is that they have difficulty accessing e.g. under low furniture due to the way the mop frame and the drawbar are mounted together.

The invention is intended to overcome the drawbacks mentioned in the prior art.

Accordingly, it is a first object of the invention to provide a mop body whereby the attachment end between the cleaning fabric and the mop body base plate is not weakened by repeated application and removal of the cleaning textile.

The structure of the mop body is to be kept as simple as possible without reducing the equipment or functions of the mop body.

It is a further object of the invention to provide a mop body where the attachment head between the mop body and the push rod allows the mop body and the cleaning cloth attached thereto to the plate base of the mop body to be pushed into tight, shallow spaces such as furniture.

The mop body according to the invention achieves the aforementioned objects.

The mop body according to the invention is characterized in what is set forth in claim 1.

More particularly, the invention relates to a mop body for cleaning textiles, the mop body comprising an elongated housing, the cover provided with a pivotable bracket for adjusting the thrust arm, and an elongated plate base associated with the housing cover provided with means for cleaning textile. The polymer mop body casing cover is formed in one piece by joining a harder cover casing and a softer cover accessory, with an elongated casing plate base at the bottom edge of the casing housing integrating a plurality of webs for securing consists of a group of adjacent rigid hooks, each hook projecting from the surface of the base of the plate, whereby two adjacent areas of the base of the plate with adjacent hooks are always separated by a region of the base of the plate without hooks.

The attachment means fixedly integrated in the mop body plate base, each consisting of a set of hooks formed by rigid hooks integrated in the base plate, provides a long and similar permanent bonding effect between the cleaning fabric and the base,

Preferably, the fastening means consist of elongated regions of plate base material rotating about the edge of the plate base, each of which is provided with hook strings longitudinally parallel to the outer edge of the plate base, which is closest to the plate base area provided with the hook group. Each set of hooks then comprises a series of hooks formed by successive lines of identical hooks, in which two successive lines of hooks c are always separated by the same distance in the direction of the board base.

The housing cover of the mop body is formed in one piece by integrally connecting the cover housing part of a harder polymer such as plastic and the cover part of a softer polymer such as elastomer, in particular by injection molding. This provides the significant advantage of making the mop body simple and wear-resistant in manufacturing despite the mop's extensive equipment features such as cloth holders and liquid wipers, which are integrated directly into the mop body cover. A further advantage is the good attachment of the equipment integrated in the mop frame to the mop frame.

In a preferred embodiment of the invention, the (ul-ko) rim surrounding the mop body cover is pivoted down to the bottom edge of the cover, and the housing cover consists of two identical ridges between which the lower edge of the cover, i.e. The pivotable bracket, in turn, consists of a mounting bracket having a bracket pin having a pivoting part to which a fitting is pivotally pivotally engaged. By now arranging the mounting pin, which acts as a swivel axial axis, into the plane of the lid, the adapter can be coupled to the mounting bracket so that the adapter is pivotable in the width of the mop frame around the mounting pin mounting pin extending close to the mop frame. This achieves the important advantage of securing the mop body and the tiller arm so that the mop body can be pushed into the shallow spaces.

Preferably, the bracket comprises a swivel body swivelable mounting bracket having a fastening pin to which the mooring body is pivotally engageable, wherein at least the fastening pin is disposed on the end of the mating body so that the swivel body

The closest prior art to the invention is disclosed in GB 2503908, which discloses a mop body which can use various cleaning tools which can be made by injection molding. However, this publication does not mention or suggest that the mop body cover be formed into a single piece by integrally molding a harder housing part and a soft accessory part.

A little further art is known from EP 20130000 A1. It depicts a mop body which, however, does not have an integral part integrated with injection molding.

Further, US 2004074520 discloses a mop, which may have injection molding detent hooks. However, this publication does not disclose the integration of a soft accessory into a harder housing by injection molding.

Figs. 1-2 show a mop body 1 consisting of an elongated housing 2 with a lid 20 formed by injection molding into a single piece and provided / provided with a separate pivotable bracket 6 to which the push arm (not shown) can be fitted via a bracket 6 adapter 62. The mop body 1 is made of polymer and its cover 20 consists of a housing part 4 and an accessory part 5. The elongated plate base 3 of the cover 20 associated with the cover 20 of the cover 20 of the mop body 1 is provided with fastening means 31 for non-cleaning textiles. .

Further, Figs. 1-2 show how the cloth holder cover 20, its ridges 8 are provided with seats for the linen holders 51 and furthermore the front edge of the cover 20 is provided with a liquid wiper 53.

The structure of the fastening means 31 integrated in the plate base 3 according to the invention is illustrated in Figures 3B and 9.

Figures 4A and 4B show the construction of the housing part 4 and the accessory part 5 of the cover 20.

Figures 5-7, in turn, illustrate the ridges 8 of the housing part 4 of the cover 20; 8 ', 8' and the structure 6 of the drawbar bracket to be placed on the plateau 44. The bracket 6 consists of a mounting bracket 61 that is pivotable in the width direction of the mop body and has a retaining pin 611 which acts as a pivot axis.

Fig. 8 shows the structure of the interior 7 of the mop body 2 and the plate base 3 viewed from the direction of the interior 7. Vertical supports 9 are formed between the housing cover 20 and the associated plate base 3 and extend through the interior 7 of the hollow housing 2.

In the following, the invention will be described in more detail with reference to the foregoing general description of the figures and the figures.

An important aspect of the invention is the manufacturing of the housing cover 20 in one piece, in particular by injection molding.

The cover 20 of the housing 2 consists of two higher ridges 8; 8 'and 8; 8 ”(viewed from level 3 of the tread) and 44 from the lower plateau between the ridges (again from the level 3 of the tread). The plateau 44 runs along the ridges 8; 8 'and 8; 8 "at the level of the base 82 and the level of the plane of the plateau being substantially parallel to the plate base 3.

Ridges 8; 8 'and 8; 8 'are identical, with a plateau 44 lower than the ridges 8, viewed from a plane passing through the lower edge of the deck 20. The surface of the plateau 44 is approximately parallel to the plate base.

On the other hand, the cover 20 of the housing 2, i.e. the ridges 8 and the plateau 44, can also be said to be formed by injection molding of the housing part 4 and the accessory part 5 as shown in Figures 4A and 4B. Preferably, the lid 20 is formed by integrating the lid housing part 4 of a harder polymer, such as a thermosetting plastic, and the lid accessory 5, of a softer polymer, such as an elastomer, by injection molding.

In this case, the housing part 4 consists of a plateau 44 and a base part 82 of the ridges 8. The housing part 4 made of a suitable plastic consists of identical ridges 8; 8 'and 8; 8 ”from base 82; 82 'and 82; 82 ', with plateau 44 between them.

The accessory part 5, in turn, comprises an upper portion 81 of the ridges 8 having holes in the tab holders 51 and a liquid wiper 53 at the front edge of the lid. There is an open space between the ridges 81: 8T, 81 '; 82 'and 82; 82 ”of the plateau 44 between them.

Each of the ridge bottom portions 82 'or 82' of the housing portion 4 has two types of through openings 821; 821a and 821; 821b, which can be injection molded into the tops 81 of the ridges of the accessory part 5; 8T, 81 'holes 811 in ridges 8; 8 'and 8; 8 ”to form the cloth holders 51a and 51b.

The accessory part 5 has two types of holes engageable with apertures 821 of the ridge bottom portion 82 and are designated by reference numerals 811a and 811b in FIG. 4B. Said ridges 8; The holes 811 of the 8 ', 82 "upper part 81 ;: 8T, 81" are either moderately narrow elongated slits 811b arranged in elastomeric tops of ridges 81 ;: 8T, 81 "or slits 811a extending in a plurality of directions from a small central opening.

Each ridge 8; The 8 ', 8' cloth holder 51a or 51b is thus always formed by the bottom portion 82 of one of the ridges; 82 or 82; 82 "through a through opening 821a or 821b and the like at the top of either ridge 81; 81 'or 81; 81 ”hole 811a or 811b.

The fluid wiper 53 is the tops 81 of the ridges of the accessory part 5; An elongate material bridge connecting the 81 ', 81' attached to the tops of the ridges 81; 81 'and 81; 81 ”at the front.

By combining injection molding or otherwise, the housing part 4 and the accessory part 5 shown in Figures 4A and 4B end up in the one-piece structure of the cover 20 of the housing 2 shown in Fig. 8 'and 8; There is a wiper 53 at the leading edge of the ridge 8 and the ridge 8 and two types of cloth holders 51 in the ridge 8. The fit of the bracket 6 is arranged in the transverse direction of the deck.

An important aspect of the invention is the integration of the fastening means 31 to the plate base such that the fastening means 31 is formed of a material of the plate base, in particular a plastic material of the housing part. This enables the cleaning fabric to be repeatedly detached from the fastening means 31 of the base plate 3 and the fastening means to the base without substantially reducing the retention capacity of the fastening means.

As shown in Figs. 1 and 2, the rim 41 surrounding the cover 20 of the housing 2 is pivoted downwardly to the lower edge 41a of the cover. An elongated plate base 3 is welded to the lower edge 41a of the cover, the shape of which corresponds to the shape of the cross-sectional profile of the cover 20.

Figure 3B shows how a plurality of cleaning textile fastening means (31; 311, 312 ...) is integrated with injection molding in the elongated sheet base 3 associated with the lower edge 41a of the cover housing part 4, and Figure 9 shows the structure of one single fastening means 31. Each fastening means (31; 311, 312 ...) is formed, as shown in Fig. 9, by a group 311b of adjacent rigid hooks 31b in which each hook 31b made of sheet material extends from the surface of the sheet bottom region 31a. Two adjacent plate base regions 31a, 31a with hook groups 311b are always separated by a plate base region 31c without hooks. In the embodiment of the plate base according to the invention according to Figure 3, the plate base 3 has two types of fastening means which differ mainly in the number of hooks contained in the hook group 311b. The various hook groups 311b are indicated in the figures by the symbols 311b1 and 311b2.

As shown in Fig. 9, the hook set 311b is formed by a series of hook lines 311d formed by successive similar hook rows 311c, wherein two successive hook rows 311c are always separated by the same distance in the direction of the base 3. Each hook row 311c always has a certain number of adjacent hooks 31b with the same distance between adjacent hooks, so that the width of the hook rows 311c remains the same in the width direction of the hook string 311d. The shape of the individual hook 31b is shown in Fig. 8 at the top right and comprises a body with two similar gripping lugs 31b1 at the top; 31 b1 ', 31 b1'.

The width of the area 31a occupied by the hook set from the plate base 3 is then determined by the width of the hook line 311c and the number of successive hook lines 311c. Because within each row of hooks the distance between adjacent hooks 31b is the same, the difference between the different hooks in groups 311b1, 311b2 is essentially how large a range of hooks 31a occupies a plate base 31a in the direction of hook group 312, i.e., how many hooks.

As shown in Figure 9, each hook set 311b is arranged close to the outer periphery of the bottom of the multifunction mop 3 so that the longitudinal direction of the hook string 311d of the hook set 311b is always parallel to the outer edge of the plate base 3 at the hook set 311b.

The multifunctional mop cover 20 is made to project into low spaces, such as under the furniture, by arranging the attachment between the cover and the handle (not shown in the figures) such that the handle can be practically pivoted almost parallel to the base of the plate 3.

To achieve this object, first, the fastening between the fastening lug 61 of the bracket 6 and the cover 20 is arranged such that the fastening pin 611 of the fastening bracket 61 is arranged as a pivot axis extending longitudinally of the deck extending close to the surface 44 of the platen 44 . Second, the adapter 62 is secured to the hinge portion 610 of the mounting lug 61, which has a width in the longitudinal direction of the cover 20 that is less than the width of the plateau 44. The attachment point 610a between the adapter 62 and the mounting lug 61 is located above the ridges 8 from the direction of the plate bottom when viewing the ridges. An important advantage of this embodiment of the invention is that the attachment of the mop body and the tiller arm is such that the mop body can be pushed into the shallow spaces.

Thus, the adapter 62 is arranged to be coupled to a low point of the mop frame, i.e. to the mounting pin 611 of the mounting bracket 61 attached to the platform 44 such that the adapter 62 is pivotable at the platform 44 about said mounting pin 611 which itself is arranged to run parallel to the plane of the mop body.

The bracket 6 is formed by an adapter 62 and a mounting bracket coupled thereto. For example, the cross-sectional profile of the adapter 62 is circular, whereby a rod-shaped rod having a circular cross-section can be fitted. The fitting 62 engages the hinge portion 610 at the top of the fastening lug 61 of the bracket 6 by a pivot attachment that allows the fitting 62 to pivot about the hinge portion 610 and the fitting point 610a (pivot point) in the longitudinal direction of the cover 20.

The mounting lug 61 is fastened very close to the plane of the surface of the plateau 44 via the fixing pin 611 (pivot axis) of the lower portion of the mounting bracket. The platen 44 has a groove 441 extending longitudinally of the cover 20 from the plane boundary edge 8a 'of the first ridge 8' to the plane boundary edge 8a 'of the second ridge 8'. The retaining pin 611 is now mounted such that it passes over the groove 441 of the plateau parallel to the groove 441 and its ends 6111, 6112 are disposed in the interior of the ridges 71 at the groove 441 of the plateau. In addition, the lower surface contacting the platen surface 44 of the securing pin 611 may have a projection 613 which is adjustable in the groove 41 of the plateau surface 44.

The kit-brake formed by the ends of the fastening pins 6111, 6112 and the ends of the supports 612, in turn, prevent the pivoting fastening pin 611 acting as a pivot axis, and thus prevent the pivoting strut 62 from being swiveled by the longitudinal direction in the width direction of the deck.

Attached to the interior space 71 of the ridges 8, to the inner surface 83 of the ridges, are the brackets 612 of the fastening pins, the inside of which the ends 6111, 6112 of the fastening pins can be fitted. The struts 612 are preferably pocket or cup-like formations which are attached on one side to the inner surface of the ridge interior 71 and taper strongly at their ends (cf. Figs. 7A and 7B). Each end 6111, 6112 of the fastening pin 611 has a transverse groove 611a of the fastening pin which forms a friction brake with the conical end 612a of the support 612 when in contact with said support end 612a.

A multifunctional mop according to the invention has been described above, wherein the mop body cover (20) is formed by one-piece bonding of a harder polymer such as a plastic cover (4) and a softer polymer such as an elastomer lid (5). Injection molding is a method of manufacturing complex molded parts. In it, the molten plastic is injected into a mold where it cools to the desired shape. A continuous injection molding machine is often a very highly automated batch process whose cycle can be divided into eight partially simultaneous parts: 1. Closure of a two-part mold made of interchangeable parts; a new batch of molten plastic in the cylinder of the injection molding machine 5. Cooling: product solidification in the mold, often the longest of cycles 6. Mold release 7. Ejection of a solid body, here ejection of a cover 8. 8. Break time: finished pieces fall between the mold halves

The accessory part and housing part of the mop body according to the invention were joined by the above method comprising steps 1-8.
