OBJECT OF THE INVENTION
[0001] The present invention relates to an information holder, which has been especially
conceived to be used in the riser of escalators, such as those found in metro stations,
train and bus stations, shopping centres, etc.
[0002] The object of the invention is to achieve a holder which can be quickly, simply and
efficiently fixed to a discontinuous surface, such as the grooved surface of said
escalators.
BACKGROUND OF THE INVENTION
[0003] As is obvious, escalator steps, specifically the riser thereof, are a suitable place
to position messages, whether informative or advertising, since said messages accompany
the observer in the normal displacement of the escalator, wherein the former is carried
by the latter facing and close to it, which is optimum to capture the messages.
[0004] Up to now, and despite their suitability, escalators have hardly been used for said
informative purposes, due to their structure which, specifically for the riser, which
is most suitable to implant the information, has a grooved structure, specifically
based on a plurality of vertical grooves, very close together, forming a toothed profile,
grooves which define ribs between them, so that in the areas of the escalator wherein
this loses its slope, the ribs of a step penetrate in the grooves of the adjacent
one and vice-versa.
[0005] This entails that, if one wants to place a holder with certain information on the
front or riser of a step, with the typical configuration based on a self-adhesive
strip, after said fixing to the ribs of the step it is necessary to cut and eliminate
the strips of the holder facing the grooves so that they can continue to be operational.
This task of cutting and waste elimination is so slow, laborious and, consequently
expensive, it makes escalators useless as graphic information carrying elements, especially
when, as is typical, said information should be changed over time.
DESCRIPTION OF THE INVENTION
[0006] The information holder proposed by the invention resolves in a fully satisfactory
manner the aforementioned problems, permitting its quick fixing to any step of an
escalator, furthermore, simply and efficiently, and without negatively affecting the
functioning of the escalator in the slightest.
[0007] For this, and more specifically, the holder the invention proposes is comprised of
a plurality of strips, whose width coincides with the ribs of the escalator, with
variable length in accordance with the size of the graphic message and spaced out,
in turn, in accordance with the width of the escalator grooves, said strips carrying
the related graphic information, obviously on which has to be its front side and are
joined together by a holder sheet, provided with an adhesive, suitable to keep said
strips stable until the definitive assembly thereof on the step.
[0008] On their opposite or rear side, said strips have, in turn, a layer of contact adhesive,
duly protected by a common sheet of paraffin, silicon or similar paper, removable
when the information holder is implanted on the step riser, so that the adhesive is
left uncovered and can come into contact with the ribs thereof.
[0009] In accordance with this structure and as is evident, after the manufacturing and
graphic representation of the holder, this reaches its place of implantation on the
information carrier strips housed between the holder sheet and the protector sheet,
initially eliminating said protector sheet, i.e. the rear sheet of the unit, so that
the adhesive of the information carriers remains uncovered, a situation wherein it
is sufficient to duly place, for example, one of the end strips opposite the corresponding
rib of the step, so that on extending the holder as a whole on said step, the rest
of the strips remain, in turn, automatically opposite the rest of the ribs of said
step. Having concluded this fixing operation, it is sufficient to pull the holder
sheet for it to be eliminated, taking with it the adhesive which joined the information
carrying strips, so that the latter will receive the front of the step riser ribs,
whilst the grooves thereof continue to be open and accessible in the clearance between
steps.

PREFERRED EMBODIMENT OF THE INVENTION
[0011] In the light of said figures, it can be observed how the information holder which
the invention proposes is formed from a plurality of narrow parallel strips (1), coinciding
in size and position with the classic front ribs on the riser (2) of the escalator
steps, such as that shown in figure 6, these strips (1) being fixed on their front
side to a holder sheet (3) by a suitable adhesive, so that said holder (3) keeps the
strips (1) duly spaced out in accordance with the width of the grooves which define
the aforementioned ribs on the escalator steps (2).
[0012] The strips (1) are coated on their rear side with a layer (4) of contact adhesive,
by means of which they will be fixed to the ribs of the riser (2) of the step chosen
for this purpose, the contact adhesive (4) corresponding to all the strips (1) of
a certain information holder, protected with a common sheet (5) of paraffin, silicon
or similar paper, as is especially observed in figure 2.
[0013] Obviously, the set of strips (1) corresponding to a determined information holder,
will be provided on their front side with graphics (6) forming the relevant graphic
information, which, in principle, is hidden by the sheet holder (3), for which purpose,
in the latter, there may exist the same graphic information (6') to facilitate the
identification of the content of the holder, especially when there are several messages,
different from one another, which should be jointly handled, or instead, said holder
(3) can be transparent to view the graphics (6) through it.
[0014] In accordance with this structure and from structure of the holder shown in figures
1 and 2, wherein this can be freely transported and handled, when it is mounted on
the steps (2) of an escalator, the protector sheet (5) is initially eliminated, meaning
that both the rear side of the strips (1) carrying the information and the contact
adhesive on its rear side remain uncovered, a situation wherein all the strips maintain
their relative position thanks to the existence of the front holder sheet (3), permitting
their correct implantation and fixing to the riser (2) of the chosen step.
[0015] After said fixing, wherein a strip (1) remains opposite a rib (7) of the step, one
achieves that the remaining strips are simultaneously facing the remaining nerves,
and it is sufficient to eliminate the holder sheet (3) so that the front side of the
strips (1) is visible and so that said free strips leave the grooves (8) of the step
(2) free, situated between them and whose accessibility is vital for the normal operation
of the escalator.
1. Information holder, which being especially conceived to permit transferring a graphic
message to the riser of one of the steps of an escalator, with a discontinuous surface,
based on narrow parallel ribs between which, in turn, grooves are established, is
characterized in that it is comprised of a plurality of adhesive strips, physically independent from one
another, whose width coincides with that of the escalator step ribs and fixed removably
to a front holder sheet, on which they are spaced out, in turn, in accordance with
the width of the step grooves, said strips incorporating on their front side, below
said holder sheet and as a whole, the graphics corresponding to the appropriate message
in each case.
2. Information holder, according to claim 1, characterized in that the rear side of said strips is coated with a layer of contact adhesive, which is
protected, until the time the holder is used, by a protector sheet, of paraffin, silicon
or similar paper, common for all the holder strips.
3. Information holder, according to the previous claims, characterized in that said strips are also fixed to the front holder sheet also by contact adhesive, but
in this case, integrated in said holder sheet, so that, after the strips are fixed
to the ribs of the step, the front side thereof remains uncovered when the front holder
sheet is eliminated.
