[0001] The present invention relates to a floor mop which introduces features of novelty
and inventive activity over the prior art.
[0002] Many types of floor mop are currently known which comprise a gripping handle and
a part in the form of a disc for securing the cloth of the mop. The cloth is customarily
formed by sheet-form elements in one piece, imitating the manual cloths traditionally
used, or in some cases the cloth is substituted by a group of braids forming a mass
which imitates the mentioned cloths. Owing to their construction, the floor mops known
at present have a reduced functional efficiency, like the mops traditionally known
and used.
[0003] The floor mop forming the subject-matter of the present invention has a novel structure
intended to achieve a more efficient and longer-lasting functioning of the mop and,
at the same time, some structural features which render its manufacture and assembly
more economical.
[0004] The mop forming the subject-matter of the present invention is formed firstly by
a combination of various groups of cleaning elements in the form of sheet-form strips
of absorbent wiping material which adopt an arrangement of a number of layers, forming
various groups distributed radially around the axis of the mop handle.
[0005] Each of the cleaning elements is preferably in the form of an elongate strip which
is fastened in the central portion or securing hub of the mop and its handle, in a
regular or irregular radial arrangement, the mop preferably being formed by a first
layer or upper layer based on strips of woven material, an intermediate layer based
on strips of braid and a lower layer or closing layer based on strips of non-woven
material. The combination of the strips of woven and non-woven material and the strips
of braid in the mentioned distribution confers features of special efficiency on the
mop.
[0006] The holding of the individual sheet-form elements in the central portion or securing
hub attached to the handle is effected by means of a system of hollow rods which exhibit
considerable radial resilience, having near their ends an external frustoconical structure
which forms a suspension hook-like border having a structure such that it fits in
recesses shaped to mate with the securing plate, which is penetrated by the hollow
rods. The securing plate is formed by a moulded part having a large central opening
permitting the passage of liquids and also has a series of lower reinforcing ribs
for increasing its strength, which ribs preferably start in the immediate vicinity
of the housings for the frustoconical tops of the hollow rods.
[0007] According to another embodiment of the invention, the mop may be formed by a layer
of upper strips of the woven or non-woven type and a lower layer of braids. Equally,
consideration may be given to a variant based on an upper layer of strips of woven
material and a lower layer of strips of non-woven material. According to another variant,
the mop may be formed on the basis of an upper layer composed of strips of non-woven
material and a lower layer composed of strips of woven material.
[0008] In any case, the arrangement of the cleaning strips will be in regular or irregular
radial form and they will be secured in an analogous manner by means of a reinforced
closing plate and hollow rods.
[0009] For a better understanding of the invention, some explanatory drawings of a mop produced
in accordance with the present invention are appended by way of example.
[0010] Figure 1 shows a section through a mop produced in accordance with the present invention,
Figures 2, 3, 4 and 5 each showing sectional details through the indicated sectional
planes.
[0011] Figure 6 is a bottom view of the central portion receiving the cleaning strips of
the mop.
[0012] Figure 7 shows a section through the indicated sectional plane of the securing portion
of Figure 6.
[0013] Figures 8 and 9 show views, in section and in accordance with a plan view, respectively,
of the central portion or shield for securing the cleaning strips.
[0014] Figure 10 shows a detail of the securing of the central shield with respect to the
part for supporting the strips.
[0015] Figures 11 and 12 show respective sections of a variant of the present invention.
[0016] Figures 13 and 14 are sections similar to those of Figures 11 and 12, corresponding
to a second variant.
[0017] Figures 15 and 16 show sections corresponding to another variant.
[0018] As shown in the Figures, the present invention comprises a number of elongate cleaning
strips of variable width, such as 1, 2 and 3, which are arranged radially in a regular
or irregular form with respect to a securing portion 4 of the moulded type, preferably
of plastics material, which has a cavity 5 for housing the shaft of the mop. The strips
forming the cleaning elements are secured simply by pressure from the closing shield
6 fitted on the securing rods 7, 7', ... which are provided in varying number at the
flange-shaped plate 8 of the securing portion 4. It is a characteristic feature that
the shield 6 has a central opening 9 permitting improved entry and discharge for fluids
and likewise that the rods 7, 7', ... are hollowed out axially in order to achieve
improved resilience and their lower edges have substantially frustoconical widened
portions, such as 10, 10', ..., which are held in mating housings 11, 11', ... on
the lower face of the shield 6. The shield 6 has, on the said lower face, reinforcing
ribs 12, 12', 12", which vary in number in accordance with the number of securing
rods and are arranged on the lower face of the shield in order to improve the rigidity
thereof.
[0019] In a preferred version, the layers of cleaning elements are composed of a first layer
of strips 1 of absorbent woven material and, below that layer, a layer of strips of
braid 2 and, further down or at the bottom portion, a layer of strips 3 of non-woven
material.
[0020] This combination gives rise to very improved features of absorption and wringing
out which optimise the functional character of the mop.
[0021] According to the variant shown in Figures 11 and 12, the mop is produced by means
of an upper layer of strips 13 of the woven or non-woven type and a lower layer of
strips 14 of braid, this being a simplified version which may be effective for certain
types of cleaning.
[0022] In the variant of Figures 13 and 14, the upper layer of cleaning elements is composed
of a number of strips 15 of woven material and the lower layer 16 is composed of a
number of strips of non-woven material.
[0023] In another embodiment which is a variant of the mop of the present invention and
which is shown in Figures 15 and 16, the first layer is composed of a number of strips
17 of non- woven material and the lower layer 18 is composed of a number of strips
of woven material.
[0024] By means of the arrangement which has been explained in the preferred embodiment
and in the embodiments constituting variants of the present invention, a very efficient
construction of the mop is obtained which adds to its specific, very efficient, cleaning
features a very economical construction, being simple to assemble and having optimum
securing features for the cleaning elements.
