Description

A WINDSCREEN WIPER
This invention relates to a windscreen wiper, which is also known as a
windshield wiper.
The invention relates in particular to a windscreen wiper which has a curved
backbone and which may have a varying width and/or thickness. It will be appreciated
by those skilled in the art that the backbone may be in the form of a beam that is
curved in a plane or may have a compound curvature. The beam will have width and
thickness dimensions. The beam will also have a radius of curvature at each point along its length.
The applicant has conducted substantial analysis and experimentation and
believes that he has found a relationship between the width, the beam material's
Young's modulus and the total length of the beam and the thickness, the beam
material's Young's modulus and the total length, which provides a windscreen wiper
that operates in an improved manner.
In this specification, the term "spatially consolidated" is to be understood,
unless the context clearly indicates otherwise, to mean that the actual perimeters of
a cross-section coincides with the shortest possible perimeter encapsulating that
cross-section. According to a first aspect of the invention there is provided a windscreen
wiper which includes
an elongate curved backbone which is of a resiliently flexible material having
a Young's modulus of between 50 to 350 GPa, the backbone having a substantially
spatially consolidated cross-sectional profile at substantially all points along its length,
in which the magnitude of the width at substantially the widest point along the
backbone, Wm (expressed in millimetres) is at most (-8.889. 1 0 ° * E + 0.05378) *
L - 5.25, where L is the total length of the backbone expressed in millimetres and E
is the Young's modulus of the backbone material expressed in GPa.
Further according to this aspect, there is provided a windscreen wiper which
includes
an elongate curved backbone which is of a resiliently flexible material having
a Young's modulus of between 50 to 350 GPa, the backbone having a substantially
spatially consolidated cross-sectional profile at substantially all points along its length,
in which the ratio of the magnitude of the width at substantially the widest point
along the backbone, to the total length L of the backbone, Rw is at most (-8.889.10~5
* E + 0.05378) - 5.25/L, where L is the total length of the backbone expressed in
millimetres and E is the Young's modulus of the backbone material expressed in GPa.
According to a second aspect of the invention there is provided a windscreen
wiper which includes
an elongate curved backbone which is of a resiliently flexible material having
a Young's modulus of between 50 to 350 GPa, the backbone having a substantially
spatially consolidated cross-sectional profile at substantially all points along its length, in which the magnitude of the thickness at substantially the thickest point along the backbone, Tm (expressed in millimetres) is at most 0.0007 * L - 0.0027407 * E +
1 .3781 4, where L is the total length of the backbone expressed in millimetres and E
is the Young's modulus of the backbone material expressed in GPa.
Further according to this aspect, there is provided a windscreen wiper which
includes
an elongate curved backbone which is of a resiliently flexible material having
a Young's modulus of between 50 to 350 GPa, the backbone having a substantially
spatially consolidated cross-sectional profile at substantially all points along its length,
in which the ratio of the magnitude of the thickness at substantially the thickest point
along the backbone to the total length L of the backbone, R, is at most 0.0007 -
(0.0027407 *E - 1 .3781 4)/L, where L is the total length of the backbone expressed
in millimetres and E is the Young's modulus of the backbone material expressed in
GPa.
The material of the backbone may be a composite material. In this case, the
Young's modulus will be that of the composite material.
The total length of the backbone may be between about 300mm to 1 200mm.
The backbone may have a varying width and or thickness, along its length. The
backbone may have a free form curvature in a plane or may have a compound
curvature (that is, curved in two planes). The invention is now described, by way of example with reference to the accompanying drawings, in which:
Figure 1 shows a schematic perspective view from above of a windscreen 5 wiper in accordance with the invention;
Figure 2 shows a side view of the wiper of Figure 1 in an unloaded free-form
condition;
Figure 3 shows a graph indicating the variation of width of the backbone of the windscreen wiper shown in Figures 1 and 2;
0 Figure 4 shows a graph indicating the variation of thickness of the backbone of the windscreen wiper shown in Figures 1 and 2; and
Figure 5 shows a graph indicating the free-form co-ordinates of the centre line
of the backbone of the windscreen wiper shown in Figures 1 and 2.
5 In the drawings, a windscreen wiper in accordance with the invention is
generally designated by the reference numeral 1 0. The windscreen wiper 1 0 includes
a backbone 1 2 which is in the form of a beam and a rubber wiper blade 14. The
beam is made from spring steel having a Young's modulus of 200 GPa. The length
of the beam is 600mm. The beam has a rectangular cross-sectional profile at all
0 points along its length. Thus, the beam has a width dimension W and a thickness
dimension T as shown in Figure 1 . The beam tapers both in width and thickness from
its centre toward its free ends or tips as shown in Figure 3 and Figure 4 respectively.
Figure 3 illustrates the beam width (in millimetres) at various positions along the
length of the beam, which is also measured in millimetres. Figure 4 illustrates the 5 thickness of the beam (in millimetres) at various positions along the length of the
beam which is also measured in millimetres. The beam is curved longitudinally, in a plane, with a predetermined radius of curvature R at every point along its length as shown in Figure 2. Figure 5 shows the
beam centre line co-ordinates relative to the position along the length of the beam (in
millimetres) .
With the given formulas, it can be determined if the wiper, as described in the
drawings conforms to the invention. The width of the beam 1 2 at its widest point along the beam 1 2, Wm (expressed in millimetres) is 1 5.4 as shown in Figure 3.
According to the first aspect of the invention, the magnitude of the width at the
widest point along the beam 1 2, Wm (expressed in millimetres), where L is 600 mm
and E is 200 GPa, should be less than (-8.889.1 0 5 * E + 0.05378) * L - 5.25 = (-
8.889.10 5 * 200 + 0.05378) * 600 - 5.25 = 1 6,35 mm. The width Wm of the
wiper therefore falls within the scope of the invention.
The thickness of the beam 1 2 at the thickest point along the beam 1 2, Tm
(expressed in millimetres) is 1 .2 mm as shown in Figure 4. According to the second
aspect of the invention the magnitude of the thickness at the thickest point along the
beam 1 2, Tm (expressed in millimetres), where L is 600 mm and E is 200 GPa, should
be less than 0.0007 * L - 0.0027407 * E + 1 .37814 = 0.0007 * 600 - 0.0027407
* 200 + 1 .3781 4 = 1 ,25 mm. The thickness Tm of the wiper therefore also falls with the scope of the invention.
