[0001] This invention relates to an improved method for the production of numerals and numerals
produced in accordance with the method.
[0002] Numerals are used for a multifarious variety of purposes for numbering houses etc.
Normally a stock of ten numerals have had to be kept by distributors, wholesalers
and retailers. The demand for certain numerals may be greater than for other numerals
and hence maintaining adequate stocks of numerals for customers is complicated. An
object of the invention is to avoid the above drawbacks by reducing to one the number
of numerals to be stocked.
[0003] According to the invention there is provided a method for the production of numerals
characterised by selecting a basic numeral, marking the basic numeral (along b) for
severance to produce other numerals within the set 1 to 9 and 0 and severing selected
unrequired residue (a,
al,
a2 ... d,
dl,
d2, d
3) from the basic numeral to produce a remainder of the basic numeral which constitutes
a chosen numeral.
[0004] Advantageously, the basic numeral is an 8 from which all the other numerals from
0 to 7 and 9 can be derived, An alternative to the 8 might be chosen but then fewer
numerals could be derived by practising the present method.
[0005] The invention also provides a basic shape adapted to be converted into other numerals
within the set 1 to 9 and.0, characterised in that the basic shape comprises the outline
of a comprehensive number which is one numeral of the set, the shape possessing markings
or lines (b) of weakness defining selected portions of the shape which are detachable
selectively therefrom to leave a remnant of the shape constituting a chosen numeral.
Again, the preferred severable shape has the outline of the numeral 8.
[0006] It will be appreciated that the unrequired residue severed from the basic numeral
shape in producing a given numeral would constitute integral portions of other numerals
which might instead be produced from the basic numeral shape.
[0007] The invention will be described now by way of example with reference to the accompanying
drawings:-
Fig. 1 is a plan view of a numeral 8;
Fig. 2 is a plan view of numeral 0, 1, 2, 3, 4, 5, 6, 7 and 9 formed from the numeral
8 showing the discarded material by dotted lines;
Fig. 3 is a plan view from below of the numeral 8 showing markings or score lines
indicating the material to be discarded to create any particular numeral from 0 -
7 and 9.
[0008] Fig. 1 shows a stylised numeral 8 and Fig. 2 shows the numerals produced by severing
and discarding the material not required for any one of the numerals 0 - 7 and 9.
[0009] Fig. 3 shows the demarcation lines b on the numerals for the production of a particular
number. As will be seen, the lines b traverse the stylised, rectilinear 8 and are
aligned with its internal edges which border the upper and lower openings of the numeral.
[0010] In forming the numeral 0 the surplus material a is discarded.
[0011] Two numerals 1 are available by discarding the material a, a
1, a
2;. The numeral 2 is formed by discarding the material c, c
1 and d
3 and for the numeral 3 by discarding the material c
1 and c
3.
[0012] The numeral 4 is formed by discarding the material a
1, a
2, c
3 and c4 and the numeral 5 by discarding the material c
3 and d
l, or alternatively c
3, d and d.
[0013] The numerals 6 and 9 are formed by discarding the material d and d
1 or alternatively only the material d
3 and the numeral 7 by discarding the material a
1, a
2, c
2, c
3, c
4 and optionally the material
cl.
[0014] The numerals may be produced by injection moulding from plastics material or by cutting
from sheet plastics material formed of less thickness along the demarcation lines
b to facilitate cutting or breaking along the lines for the required numeral.
[0015] Alternatively the numeral 8 may be of metal with grooves or partial shear, to form
the demarcation lines b and which may be visible on the front or back of the numeral
8.
[0016] An impact adhesive with closed cell foam is applied to the back of the numeral, with
a protective cover or liner for stripping off prior to applying the chosen numeral
to a door or other surface or anchorage.
[0017] Attachment of the numeral to a substrate can be made by pins or screws instead of
by means of an adhesive.
[0018] Alternatively other numerals than 8 may be selected as the basic number, but then
it will not be possible to derive all the numbers from 1 to 9 and 0. For example,
if the chosen basic numeral were 6 or 9, only the numerals other than 0, 2, 3 and
8 could be obtained.
[0019] It is envisaged that the comprehensive numerals convertible into other numerals could
be educationally useful, and for use as an educational toy could be supplied without
any anchoring means such as adhesive, pins or screws.
[0020] As will be recognised, adoption of a single comprehensive numeral, ready weakened,
represents a significant advantage to the user, as well as simplifying manufacture
and keeping expensive tooling costs to the very minimum.
1. A method for the production of numerals characterised by selecting a basic numeral,
marking the basic numeral-(along b) for severance to produce other numerals within
the set 1 to 9 and 0 and severing selected unrequired residue (a, a1, a2 ... d, d1, d2, d3) from the basic numeral to produce a remainder of the basic numeral which constitutes
a chosen numeral.
2. A method according to claim 1, characterised by selecting 8 as the basic numeral,
marking the numeral 8 along lines (b) which traverse the 8 for severance to produce
numerals from 0 - 7 arid 9 and then severing the unrequired residue to leave a remnant
constituting the chosen numeral.
3. A method according to claim 2, characterised in that the 8 is severable along lines
crossing the 8 which are aligned with internal borders defining the upper and lower
openings of the 8.
4. A method according to claim 1, 2 or 3, characterised in that anchoring means is
applied to a surface of the basic numeral for use in securing the chosen.numerals
prepared therefrom to a substrate.
5. A basic shape adapted to be converted into other numerals within the set 1 to 9
and 0, characterised in that the basic shape comprises the outline of a comprehensive
number which is one numeral of the set, the shape possessing markings or lines (b)

therefrom to leave a remnant of the shape constituting a chosen numeral.
6. A basic shape according to claim 5, characterised by being in the form of the number
8, the shape possessing markings or lines of weakness (b) defining selected portions
of the shape detachable selectively therefrom to leave a remnant of the shape, the
form of remnants producible from the shape being representative of all the numbers
from 1 to 9 and 0.
7. A basic shape according to claim 6 which comprises the form of a stylised rectilinear
numeral 8, characterised by the lines of weakness (b) traversing the shape in alignment
