Description
DESCRIPTION OF THE INVENTION
This invention is connected with the fabrication of heels for
shoes.
In the best known variety of heel, on the surface of the said heels
is reproduced by impression the plan of the heel of the foot,
called crown, placed at the end of the shaped sole for shoes. The
heel mentioned, in-reproducing an impression conventionally called
crown, follows a logical measurement fitted to the purpose of
obtaining a harmonious relationship with the back part of the shoe
which is applied according to the most suitable method, with nails
or with glue and screws. In conventional heels in use, shaped all
in one piece or made up of two elements, with their upper and lower
sections, in practice it can in any case be said that they are all
one, with separate application of a wear surface, known as
heel-cap. With the conventional method of fabrication, therefore,
the said heel being practically made up of a sole element with a
heel-cap separately applied, there was no solution to the problem
of obtaining more combinations, better effects of line, form,
color, different heights of heel and practical means of
substituting the element most subject to wear, very necessary
attributes for a more effective presentation of the product as well
as for simplicity of execution favoring industrial production. With
my invention for the fabrication of heels for shoes, with an upper
heel portion with applied an ornamental `mask` and a lower
`interchangeable` heel portion having an incorporated heel-cap with
protective trimming applied externally, I intend by means of the
various combinations to solve the problems mentioned.
The first objective of my invention is a shaped ornamental `mask,`
into which will fit the upper section of the heel in such a
position as to allow the fixing of the `interchangeable` lower
section having a protective trimming applied to the incorporated
heel-cap. This fixing will be achieved by means of a pin and small
tube incorporated in the `interchangeable` section and fitted into
the shaped housing and into the joining member incorporated in the
upper section of the heel. The four definite parts which make up
the heel can be of any material (e.g., wood, iron, aluminum, brass,
copper, plastic etc.) as long as at the point of junction the
established measurements are respected.
The second objective of my invention is exact shaping of the
internal faces of the ornamental mask so as to allow good
application of the mask to the upper-section. The external faces of
the said mask could be of different line and shape from the upper
section of the heel, and the appendix of the said mask could also
not follow the connection with the `interchangeable` lower section.
Besides, the said mask being produced in different sizes will be
able to be easily combined with the upper section of the heel. In
this way it will be possible to obtain modification in the form or
line of the heel even if the upper section of the heel has already
been applied to the shoe, completing it harmoniously.
The third objective of my invention is that the upper section of
the heel with ornamental mask will be connected with the
`interchangeable` lower section by means of a shaped pin which will
fit into the housing in the upper section of the said heel. In a
hole in the center of the external surface of the heel-cap
incorporated in the `interchangeable` section a screw is inserted,
which passing through a tube incorporated in the inside of the
`interchangeable` section will extend to the outside to enter the
aligned, concentric hole of smaller diameter in the joining member,
incorporated in the upper section, so as to screw in by means of a
self-threading portion of the said screw and allow the perfect
uniting of the two main sections which make up the said heel.
The fourth objective of my invention is to achieve the perfect
coupling the two main sections so as to render superfluous in some
cases the insertion of the screw mentioned under the previous
objective.
The fifth objective of my invention is the possibility of obtaining
a change of color in the upper section of the heel already applied
to the shoe by means of the ornamental mask; this will naturally be
possible only after disconnecting the two sections of heel. The
uncoupling of the said two sections will be effected with a
screwdriver if the sections are joined with a supplementary screw,
or by means of a nail without a point, if possible in tempered
steel, which at the moment it is desired to unjoin the parts will
be easily inserted in the hole in the center of the bottom external
surface of the heel-cap incorporated in the `interchangeable`
section. Once the said nail is inserted, if the shoe is held in the
hand and knocked on a flat surface the nail hitting the appendix of
the joining member incorporated in the inside of the upper section
will allow the parts to come apart easily, although this is almost
impossible without the said nail.
The sixth objective of my invention is that the two principal
sections which make up the said heel, as also the ornamental mask,
can be produced with completely transparent plastic materials so
that they can be used for the internal application of writing for
publicity purposes, ribbons with phosphorescent colors and other
various applications.
The seventh objective of my invention is the easy application of
the protective trimming, so as to obtain a better color contrast
between `interchangeable` section having an incorporated heel-cap
with the said protective trimming.
The eighth objective of my invention is that another mask can be
applied at will to the `interchangeable` lower section.
The ninth objective of my invention is that applying the said heel
to conventional shoes other combinations can be obtained, for
example:
A. the ornamental masks and the `interchangeable` lower section
with its protective trimming externally applied to the heel-cap
incorporated in the said `interchangeable` section, being
preferably molded in plastic in their variety of lines, forms and
colors, will be put on the market so as to be able to be bought
directly by the consumer at a ridiculous price;
B. a quick and easy substitution of the `interchangeable` section
will be possible, as also of the mask applied to the upper section
of the heel and if wanted also another ornamental mask applied to
the `interchangeable` section, an operation which can easily be
performed by the users themselves;
C. at the moment of substituting the `interchangeable` section with
a new one, the user besides having the possibility of selecting the
color and the line of the heel can also alter the height of the
heel, with a more or less high `interchangeable` section.
The tenth objective of my invention is that the fabrication of the
said heel can be adapted to heels for women's, men's and children's
shoes, whether for conventional dove-tail working, embedding,
external application to the sole of the shoe, or for working with
sole and heel all in one piece (this last case refers to the sole
and heel made up of only one element obtained by pressing and
vulcanization), and for all heights.
The elements which as one whole constitute the object of the
present invention, realized, described and illustrated in a
preferred form, can assume other forms and measurements and
variations in the single details of fabrication without going
beyond the scope of the invention itself and therefore of the
control of the present patent.
The invention will be illustrated in the following pages with
reference to the drawings shown on the enclosed sheet in which are
illustrated some forms as examples of a preferred form of
execution.

the elements assembled;
FIG. 2 is the same as FIG. 1 but the same elements are seen in
cross-section;
FIG. 3 is a cutaway view starting from line 200--200 with respect
to FIG. 2;
FIG. 4 is a view from above of the ornamental mask as illustrated
in FIG. 2;
FIG. 5 is the same as FIG. 4, but seen in cross section;
FIG. 6 is a view from above of the lower external surface of the
interchangeable section (2) relating to the incorporated heel-cap
treated with diagonal knurling, with applied external protective
trimming (3), also treated with diagonal knurling;
FIG. 7 is a cutaway view of the protective trimming in the
following FIG. 8;
FIG. 8 is a view from above of the upper internal surface relating
to the external protective trimming (3) not yet applied to the
incorporated heel-cap;
FIG. 9 is a detail seen in cross section as illustrated in FIG. 2,
completely detached;
FIG. 10 is a view from above of a nail without point serving as
extractor;
Illustrated in FIGS. 1 and 2 is the fabrication of the heel with
ornamental mask (4), with `interchangeable` lower section (2),
having a protective trimming (3) applied externally to the
incorporated heel-cap 5a, made up of an upper section (1) and an
incorporated joining member 9. having a concentric hole 7 which
extends inwards coming into direct communication with another
concentric hole 7a of smaller diameter. The upper section (1) has a
shaped housing 6 with an oblique internal surface 10, to allow the
coupling of the pin 8 incorporated in the `interchangeable` section
(2), into which it is fitted.
The `interchangeable` section (2) has on the upper surface (13) a
pin 8 which projects upwards, which, being shaped, besides
obtaining the joining of the two principal sections 1 and 2, which
make up the said heel suitable for being dismounted, will avoid any
possibility of rotation.
In the said `interchangeable` section (2) beginning from 5a there
is a circular external opening 19 which extends upwards entering in
direct communication with another opening of smaller diameter 18
continuing to pass through the said `interchangeable` section to
protrude on the outside.
In the `interchangeable` section (2) an opening 14 extends inside
downwards to stop at fixed depths 39-40-41-42 and 17 as later
illustrated in FIG. 3.
The concentric hole 18 in the `interchangeable` section (2) is
aligned to the opening 7a, the latter however of smaller diameter.
The small tube 20 is incorporated in the `interchangeable` section,
and a portion of the external surface (of the said tube 20) fits
into the internal circular housing 7 of the joining member 9
incorporated in the upper section (1).
A possible auxiliary safety screw (5) is inserted in the opening 19
and then in the concentric hole 18 of the tube 20 incorporated in
the `interchangeable` section (2), crossing it in its whole length
for a self-threading portion 26 of the screw (5) to then emerge.
The lower portion 22 of the screw (5) which is of larger diameter
with respect to the portion 24 of the said screw (5), with a
horizontal impression 22a, is divided in two by the said horizontal
impression to allow the approach of the appendix of a common
srewdriver allowing a regular rotation, assuring at the same time
the introduction of the portion 22 into the inside of the opening
19 stopping at a fixed depth. The self-threading portion 26 of the
screw (5) by screwing and inserting itself in the hole 7a in the
joining member 9 incorporated in the upper section (1) insures a
solid coupling of the two sections -1 and-2 which make up the said
heel, made to be dismountable in order to allow the
interchangeability of the section (2).
The ornamental mask (4) applied between the upper section (1) and
the `interchangeable` section (2) with its internal faces 12 and
12a covers entirely all the external faces of the upper section
(1), and at the same time a base 4a incorporated in the said mask
covers-partly the lower surface of the upper section (1), following
the perimeter of the seat of the said upper section (1) and
aligning itself with the pin 8 incorporated in the
`interchangeable` section (2). The upper internal surface 13 of the
said `interchangeable` section (2) being superimposed on the base
4a of the said mask (4), will make all one piece with the mask and
upper section (1).
The protective trimming (3) with lower external surface 3a treated
with diagonal knurling, on the outside of the heel-cap incorporated
5a in the `interchangeable` section (2), is applied by means of
four little pegs of partly cylindrical form arranged in a cross and
having generally an area covering about 270.degree. , which extend
sideways inwards and at the same time project upwards to stop at a
fixed height. The said pegs 50-52-54-56 as illustrated in the
following FIGS. 6 and 8 will fit into their respective housings
30-32-34-36 placed on the external perimeter 48 relating to the
heel-cap 5a incorporated in the lower surface of the
(`interchangeable` section (2). One face 58 of the internal
perimeter of the trimming (3) follows the same shaping as the
external face 48 in relation to the heel-cap 5a incorporated in the
`interchangeable` section (2). The upper internal surface 60 of the
trimming (3) being superimposed on the lower external surface 62 of
the `interchangeable` section (2) which together with the two faces
48 and 58 relating to the internal faces of the heel-cap in the
`interchangeable` section (2) will adhere perfectly to each other,
will guarantee solid joining and avoid any possible rotation and
expansion.
The upper section (1), the `interchangeable` section (2) and the
ornamental mask (4) are generally molded in plastic material, while
as far as the protective trimming (3) applied externally to the
`interchangeable` trimming section is concerned, it could be molded
preferably of materials more suitable for allowing greater
resistance and silence during wear (e.g. robber, coria, and nylon
etc.).
As illustrated in FIG. 4, the ornamental mask (4) has an internal
face 12 partly conical and united completely with another internal
face 12a smooth perpendicularly which closes the perimeter of the
said mask (4) extending downwards with a base completely united 4a
to the said faces 12 and 12a. The base 4a delimits an area along
the whole perimeter of the said mask (4).
Into the said mask (4) will be fitted the upper section (1) as
illustrated in FIGS. 1 and 2.
Illustrated in FIG. 6 is a view from above of the interchangeable
section (2) having a heel-cap incorporated 5a with a shaped
external face 48 with slight knurling and an opening 19 in which is
inserted a protion 22 of the screw (5) which extends inside the
following opening 18 of smaller diameter projecting on the outside
and coming into communication with the concentric hole 7a of the
joining member 9 in the upper section (1) as illustrated in FIG.
2.
Shown in FIG. 8 is a view from above of the protective trimming (3)
to be applied externally to the heel-cap 5a incorporated in the
`interchangeable` section (2), with four little pegs 50-52-54 and
56 incorporated in the internal face 58 of the protective trimming
(3), which will fit into their respective housings 30-32-34 and 36
in the `interchangeable` section (2) with relation to the lower
external surface of the incorporated heel-cap 5a as illustrated in
the the preceding FIG. 6.
Illustrated in FIG. 9 are the protective trimming (3), the
auxiliary screw (5), the `interchangeable` section (2), the
ornamental mask (4) and the upper section (1), all elements seen in
cross section and detached distinctly from each other, to be joined
as shown in FIG. 2.
As illustrated in FIG. 10, the nail serving as extractor (100) has
a perfectly cylindrical form with one end 64 having a flat surface
and the other end also with a flat surface but with a larger
diameter 66.
