Abstract
This consists of a tubular body (1) made of
thermoforming plastic material, onto whose outer surface is
tightly fitted a textile coating (2); said body (1) having
at one of its ends an inner fold (3) forming an opening (4)
whose diameter matches that of the axle (5), such that this
end of the tubular body (1) acts directly as the rotation
bearing for the axle, while at its other end the tubular
body (1) has an inner rim (6) onto which is fitted a cup (7)
with an outer groove (8) which accommodates the aforesaid
rim, as well as an axle neck (9) acting as the second
bearing for rotation around the axle (5). The actual roller
(1-7) is secured onto the axle (5) by means of a steel clip
(10) which fits snugly around a recess (11).
Description
The present invention involves a paint roller, of the
type consisting of a cylindrical body with a textile outer
coating, mounted with free rotation capability on an axle,
which extends into an arm fitted with a hand-grip at its end
for handling it.
The object of the invention is to achieve a
structurally simple, and hence economic roller which
provides, however, the highest standards of functional
performance.
Paint rollers of the aforesaid type, with a synthetic
fibre or wool outer coating which also covers the cylinder
ends, are made up of a tubular cylindrical body, onto which
is applied the textile coating, also cylindrically shaped,
but having a greater radius than that of the tubular body;
two inner caps are fitted into either end of the tubular
body, such that the textile coating folds in at the cylinder
ends, between the body itself and the end caps. Such coating
is firmly secured in position once the roller rotation
bearings are fitted inside the caps.
This solution, in addition to its structural
complexity, particularly as regards the operations required
to fit the end caps and fitting the textile coating to their
inner surface, generally involves deficiencies in the
attachment of said textile coating to the roller ends, since
in such areas the coating is not tightly fitted to the
polypropylene tube, but simply kept in place by the caps,
leading to openings in the coating which shorten the life of
the roller.
The textile envelope may be attached to the plastic
tubular core by any conventional means or using the solution
provided in Spanish invention patent 8602222, in which the
tubular body is made up of a number of plastic tube-shaped
sections, in between which are fitted a number of
intermediate rings of a heat-resistant material, with a
textile strip wound helically around the resultant core so
that, by applying heat, it becomes fixed onto the plastic
sections of same. In any case, the above-mentioned problems
concerning the complex structure of the roller and
shortening of the roller's operational life still prevail.
With a view to solving this problem, the applicant is
the holder of the Spanish invention patent under application
number 9701794, which describes a suitable procedure to
obtain a paint roller, as well as the roller obtained by
means of such a procedure and the means required for the
embodiment of same.
More specifically, such a procedure consists in taking
a cylindrical body of thermoforming plastic material, onto
whose outer surface the textile coating is tightly fitted,
and subjecting the ends of such a roller to a prior heating
stage which will allow a subsequent shaping stage in which
the roller ends are folded inside the roller itself, thus
forming an outer rounded rim, still having its textile
coating, and an inner tapering neck, onto which the
necessary bearing will be directly fitted, such that the
final result is a cylindrical roller with rounded ends
covered by a textile coating, each of these ends having an
opening of considerable diameter into which are pressure
fitted the two bearings which connect the roller itself to
the axle/handle part.
This method, while providing a fully satisfactory
solution to the aforesaid problems, involves a three-part
structure, since the roller itself is made up of three
constituent parts, which negatively affects the final cost
of the product.
The paint roller of the present invention, based on a
construction method similar to that of the above-mentioned
invention patent 9701794, as regards the use of a
cylindrical body of thermoforming plastic onto whose outer
surface a textile coating is tightly fitted, and as regards
subjecting the ends of such a cylinder to heating prior to a
subsequent shaping stage, has the distinguishing feature
that one of its ends is thermally deformed in such a way as
to form an opening with the same diameter as that of the
roller axle, such that the tubular body itself acts, at this
end, as the axle rotation bearing.
The cylindrical body is closed at the other end with
the aid of a round cup, designed with a recess which fits
into a matching rim in the cylindrical body, a substantial
part of which has been folded in, such that the cup has the
double function of closing the cylindrical body and acting
as the second bearing for rotation around the roller axle.
In addition to the foregoing structure, and in
accordance with another of the features of the invention,
said cup is provided with a steel clip which secures the
roller in position relative to the axle/handle part, for
which purpose the axle has an outer groove along its
circumference onto which the aforesaid clip is fitted.
However, the roller axlemounting clip, as well as the
corresponding groove on the axle, may be located at the
other end of the roller-axle assembly.
By means of this configuration, a considerable
structural simplification of the roller is achieved, since a
roller of such design consists of only two parts, which
evidently has a very favourable impact on its manufacturing
cost.
To provide a fuller description, and to enable better
understanding of the features of the invention, according to
an example of the preferred embodiment of same, a set of
drawings is enclosed, forming an integral part of said
description; in these drawings, by way of illustration but
without any restrictive intent, the following is
represented:
Figure 1.- Shows a schematic side elevation view of a
paint roller manufactured according to the object of the
present invention, showing a longitudinal section of the
actual roller.
Figure 2- Provides a detailed axial view of the roller
in the previous figure, illustrating the clip securing the
actual roller to the axle.
Figure 3.- Provides a detailed view of a part of
figure 1, namely the free end of the roller, according to a
version of the embodiment in which the axle fitting clip is
located at this end of the assembly.
Upon inspection of these figures, and more specifically
figure 1, it may be seen that the paint roller of the
present invention consists of a cylindrical, tubular body
(1) onto whose external surface is tightly fitted a textile
coating (2); said tubular and cylindrical body having its
ends shaped by thermoforming, specifically its free end (3)
is folded in to form an opening (4) acting as a bearing of
suitable diameter relative to the axle (5) upon which is
fitted the tubular body, while at the other end, preferably
the inner end, the tubular body (1) has an inner rim (6),
also obtained by thermoforming, onto which is fitted a sort
of cylindrical cup (7), with an external groove along its
circumference (8), such that the cup (6) is axially fitted
to the tubular body (1), leaving an inner cylindrical neck
section (9) inside which there is a steel clip (10) embedded
in the cup (7), which may be pressure-fitted, following
elastic deformation, on a groove (11) around the actual axle
(5), such that this cup (7) acts as the second rotation
bearing between the tubular body (1) and the axle (5) when
the roller is in normal use.
In the example of a practical embodiment shown in
figure 1, both the axle fitting clip (10) and the actual cup
(7) are located at the end of the axle (5) which further
extends to form the usual handle (12) ending in the typical
hand grip (13); however, said clip (10) may alternatively be
located, as shown in figure 3, at the free end of the axle
(5), i.e. mounted at the constriction (3) of the tubular
body (1) acting as a bearing, in which case, evidently, the
groove (11) to accommodate the clip will also be located at
the free end of the axle (5).
In any case, in accordance with the object of the
invention, the actual roller consists exclusively of two
component parts, the tubular body (1) and the housing pan
(7), which involves a considerable structural simplification
which leads to a reduction in the cost of manufacturing the
roller.
