Technical field
[0001] The invention relates to strips of paper or other materials used to cover and protect
floors, walls or other surfaces while painting, bricklaying or other work in general
is being carried out.
Prior art
[0002] It is well known that while painting or other building work is being carried out,
it is advisable to cover the floor or other surface areas close to the work area with
paper, plastic or other materials. In domestic use, any available paper has generally
been used, by arranging it along the surface to be protected and fixing it to this
surface with the appropriate adhesive means, usually adhesive tape and, among the
types available, usually painter's tape or coach-builder's tape (masking tape) because
of its good properties (clean, ecological, easily removable and does not leave marks
or remains on the surface).
[0003] For these tasks to be carried out professionally, there are several optimised protection
systems on the market which, in addition to providing a means of protection similar
to the domestic means of protection described above, seek to offer a notably faster
and easier method of installation in order to reduce work times. To this effect, the
main novelty of the protection systems for preferably professional use lies in the
fact that the protective material (paper, plastic, etc.) has the adhesive incorporated
into it, so that its installation is fast and simple as it does not require the adhesive
strips to be manually attached to the protective material in advance.
[0004] Among these protection systems with adhesive incorporated, two models known on the
market are of special relevance. The first of these consists of a narrow strip for
covering skirting boards and has an adhesive band incorporated into one of its side
edges. The second model, intended to be installed on larger surface areas than the
first (floors, walls, etc.), consists of a wider strip of paper than the previous
model and has a longitudinal strip of adhesive material applied in its central area,
with this adhesive material enabling the paper to be fixed to the surface to be protected.
[0005] This second model is usually presented in the form of rolls and, therefore, to prevent
the adhesive from sticking to the paper itself when it is in roll form, a strip of
non-adherent material is applied to the paper on the opposite side to the adhesive
material, in the central area of the paper so that its position coincides with the
position of the adhesive material.
[0006] The disadvantage of this second model of protective strip is that during manufacture
it is necessary to apply two types of materials onto the paper separately (an adhesive
material and a non-adherent material), which means that the manufacturing process
is slowed down and complicated. Moreover, the adhesives used are usually very strong,
which means that they leave residues on the surface to be protected once that the
paper has been removed from it.
[0007] On the other hand, it has been proven in practice that the installation of several
strips of this model arranged parallel or adjacent to each other has a clear disadvantage:
as the adhesive is located in the central area of each strip, there is no adhesive
in the area where one strip is overlapped by the adjacent strips, and therefore the
union between strips does not exist, and gaps are left where paint or dust might enter
or where the paper itself might easily become torn. It has even been demonstrated
that users opt to reinforce these areas of union by manually attaching strips of adhesive
tape, which contradicts the purpose of the product and raises doubts about its effectiveness.
[0008] For all the reasons given, the objective of the present invention is to achieve a
protective strip of paper or other materials in order to cover and protect floors,
walls or other surfaces while painting, bricklaying or other work in general is being
carried out, which has the adhesive material incorporated into it and enables larger
or smaller surface areas to be protected by means of the correct arrangement of several
portions of the protective strip either parallel or adjacent to each other.
[0009] Another objective of the invention is to achieve a correct form of sealing in the
areas of union or overlapping between the strips in the said adjacent installation
of several portions of the protective strip.
[0010] Another objective of the invention is to achieve a protective strip whose manufacture
is simplified, not requiring the separate application of an adhesive product or material
and of another non-adherent product or material.
Detailed description of the invention
[0011] In order to achieve the above mentioned objectives, a protective strip is defined
in order to cover and protect floors, walls or other surfaces while painting, bricklaying
or other work in general is being carried out, characterised mainly in that it is
made up of a protective element and a fixing element, in which the protective element
is the main component of the protective strip, and in which the fixing element is
the component that gives the adhesive nature to the protective strip, with the particularity
that the fixing element is arranged on at least one side edge of the protective strip
and that the fixing element in itself contains an adhesive area and a non-adherent
area, so that the application onto the protective element of adhesive and non-adherent
products separately is not necessary.
[0012] The protective element in question might be made of paper, plastic or any other materials
suitable for the application. The fixing element, for its part, will consist of any
kind of known tape which has one adhesive side and one non-adherent side.
[0013] In the preferred form of production of the invention, the protective strip in accordance
with the invention will include fixing elements on both side edges, and these fixing
elements will consist of strips of masking tape (painter's tape), of the type known
and used in the applications for which the protective strip in accordance with the
invention is going to be used.
[0014] In those side areas where the protective strip is gong to be given an adhesive character,
the protective element is provided with one or more gaps designed to remain covered
by the fixing element and which have a surface area smaller than that of the fixing
element.
[0015] The fixing element is placed over the protective element in those side areas provided
with the above mentioned gaps, with the adhesive area or side of the fixing element
facing towards the protective element. By placing the fixing element in this way,
two effects are achieved simultaneously: on the one hand, as the fixing element has
a greater surface area than the surface area of the gaps, it is the adhesive of the
fixing element that provides the means of physical union between the fixing element
and the protective element; on the other hand, the adhesive part of the fixing element
which is arranged in the interior of the gaps is the part that provides the adhesive
character of the whole with regard to the surface to be protected. Moreover, when
the protective strip in accordance with the invention is rolled up, the non-adherent
side or area of the fixing element comes into contact with its own adhesive area,
preventing this adhesive area from coming into contact with the protective element.
[0016] In this way, by means of the placing of a single element, the fixing element, the
effects of providing the whole with adhesive properties with regard to the surface
to be protected and of providing the whole with non-adherent properties with regard
to itself are achieved.
[0017] The protective strip in accordance with the invention is presented in roll form,
which is easily unrolled for installation onto the surface to be protected.
[0018] Given that the protective strip in accordance with the invention has adhesive areas
on its side edges, in case of different portions of the protective strip being installed
parallel to each other onto the surface to be protected, the unions between adjacent
portions will be perfectly sealed and resistant to breakage or tearing, because the
adhesive area are to be found precisely at these unions.
[0019] Moreover, the preferred form of production of the invention, which includes the use
of masking or painter's tape, offers many advantages with regard to the known solution
in which an adhesive and a non-adherent are applied directly onto the protective material:
firstly, masking tape is a known element and is extensively used in the sector, with
a guarantee of proven good operation and which inspires trust among users; secondly,
the adhesive which is present on masking tape does not leave residues or traces when
it is removed from the surface to be protected, during withdrawal of the protective
strip in accordance with the invention.
[0020] In the same way, the preferred form of production of the protective strip in accordance
with the invention has the additional advantage of providing fixing to the surface
to be protected with much greater stability or resistance to movement than the fixing
which is provided by the known strip with adhesive in its central area only.
Description of the drawings
[0021] The details of the invention can be appreciated in the figures in the accompanying
drawings, which do not seek to be restrictive as regards the scope of the invention,
but rather to help understanding of the items claimed:
- Figure 1 shows a perspective view of the improved protective strip in accordance with
the invention.
- Figure 2 shows a perspective view of the main elements that make up the improved protective
strip in accordance with the invention, shown separately.
- Figure 3 shows a perspective view of the main elements that make up the improved protective
strip in accordance with the invention, once they have been fixed together.
- Figure 4 shows a perspective view of a protective strip known in prior art, previous
to the invention.
[0022] In Figure 1, the main form of production of the protective strip (1) in accordance
with the invention is represented, in which the said protective strip (1) has the
form of a roll (10) of protective element (2) which includes two strips of fixing
element (3), arranged longitudinally in the side areas (12) or close to the edges
of the roll (10). The fixing element (3) has one adhesive side or area (5) whose function
is to provide the means of fixing the protective strip (1) to the surface to be protected
(6). In addition, the fixing element (3) has a non-adherent side or area (4) whose
function is to prevent the adhesive area (5) from adhering to the protective element
(2) itself when the protective strip (1) is rolled up, so that it is possible to correctly
unroll and install it.
[0023] The installation of the protective strip (1) onto the surface to be protected (6)
is carried out by means of rotation of the roll (10) of protective strip (1) in the
direction indicated by the arrow (11). At the same time, light pressure is applied
onto the non-adherent areas (4) of the fixing element (3), with which the adhesive
areas (5) remain firmly fixed to the surface to be protected (6), with the protective
strip (1) becoming correctly installed.
[0024] Figure 2 shows a partial view of the improved strip of the invention that corresponds
with one of the areas where the fixing element (3) is to be found over the protective
element (2), in this case in the pre-assembly situation, with both components (2,
3) separated. As can be observed in the Figure, the fixing element (3), whose width
has been represented as 'd1', includes an adhesive area (5) and a non-adherent area
(4). Moreover, the protective element (2) has a gap (9), in this case arranged longitudinally,
whose width 'd2' is smaller than width 'd1' of the fixing element (3). In this way,
the surface of the fixing element (3) is greater than the surface of the gap (9).
[0025] Figure 3, like Figure 2, shows a partial view of the improved strip of the invention
that corresponds with one of the areas where the fixing element (3) is to be found
over the protective element (2). In this case, the fixing element (3) is to be found
mounted or fixed onto the protective element (2). As can be observed in the Figure,
the fixing element (3) remains adhered to the protective element (2) thanks to the
greater surface of the former in relation to the latter, which ensures that part of
the adhesive area (5) around the gap (9) comes into contact with the protective element
(2). Moreover, the part of the adhesive area (5) inside the gap (9) provides the fixing
element that fixes the protective strip (1) to the surface to be protected.
[0026] Figure 4 shows and example of protective strip (1) known in prior art, in which the
protective element (2) is arranged in the form of a roll (10) and has a single, central,
longitudinal adhesive part, produced by means of the direct application of an adhesive
(8) onto the protective element (2) in its central area (12). With the purpose of
preventing the adhesive (8) from becoming stuck to the protective element (2) when
it is rolled up, a non-adherent (7) is applied on the opposite side of the protective
element (2), logically central and with a longitudinal shape and coinciding with the
shape of the adhesive (8). The installation of this protective strip (1) onto the
surface to be protected (6) is carried out in a similar way to that in Figure 1, by
means of the rotation of the roll (10) of protective strip (1) in the direction indicated
by the arrow (11).
1. Protective strip (1) to cover and protect floors, walls or other surfaces (6) while
painting, bricklaying or other work in general is being carried out, of the type made
up of a protective element (2) and at least one fixing element (3), in which the protective
element (2) is the main component of the protective strip (1) and is responsible for
covering the surface to be protected (6), and in which the fixing element (3) is the
component that gives the adhesive character to the protective strip (1), for which
the fixing element (3) comprises an adhesive area (5) and a non-adherent area (4),
characterised in that:
- in at least one side area (12), the protective element (2) is provided with one
or more gaps (9) designed to be covered by the fixing element (3) and which have a
smaller surface than that of the fixing element (3),
- the fixing element (3) is placed over the protective element (2) on those side areas
(12) provided with gaps (9), with the adhesive area (5) of the fixing element (3)
facing towards the protective element (2), in such a away that the part of the adhesive
(5) of the fixing element (3) that remains outside the gaps (9) provides the means
of physical union between the fixing element (3) and the protective element (2), and
the part of the adhesive (5) inside the gaps (9) provides the means of physical union
between the protective strip (1) and the surface to be protected (6).
2. Protective strip (1), in accordance with claim 1, characterised in that there is only one gap (9) in the protective element (2) along the entire length of
the protective element (2), and it has a width (d2) which is smaller that the width
(d1) of the fixing element (3).
3. Protective strip (1), in accordance with claim 1, characterised in that the protective element (2) is made of paper, plastic or other materials.
4. Protective strip (1), in accordance with claim 1, characterised in that the fixing element (3) is a masking tape or painter's tape.
5. Protective strip (1), in accordance with claim 1, characterised in that the protective strip (1) is presented in the form of a roll (10), which, when rolled
up, has the particularity that the non-adherent area (4) of the fixing element (3)
comes into contact with the adhesive area (5) of the fixing element (3), preventing
this adhesive area (5) from coming into contact with the protective element (2).
