Claims
What we claim is:
1. In a timepiece, such as a clock or watch, hour and minute hands,
a stationary face situated behind said hands, and a transparent
sweep-second disc situated in front of said hands and replacing a
normal sweep-second hand of the timepiece, so that the hands are
visible through said disc to maintain the time-indicating function
of the timepiece, such stationary face having thereon a decorative
design of a predetermined pattern visible through said disc and
said transparent disc having thereon a decorative design of a
predetermined pattern which is superimposed on the design of said
face which is visible through said disc with the design of the
latter turning with respect to the design on said face for
providing a predetermined visual effect during rotary movement of
said disc with respect to said stationary face, a transparent cover
engaging said stationary face beyond said hands and forming with
said stationary face an enclosure for said hands and disc, and a
bezel surrounding said stationary face and situated beyond said
cover, said bezel carrying indicia with which said hands coact for
indicating the time.
2. The combination of claim 1 and wherein the pattern of the design
on said face and disc are both in the form of sectors of a circle
of different colors.
3. The combination of claim 2 and wherein each of the sectors
extends through an angle of 120.degree. and the colors of said face
and disc providing at given instants during rotation of the disc
with respect to said stationary face an impression of sectors whose
areas are increasing and decreasing and of a smaller size than the
120.degree. size of said sectors.
4. The combination of claim 1 and wherein the patterns on said face
and disc coact to provide visible areas which appear to increase
and decrease in size.
5. The combination of claim 4 and wherein said stationary face is
divided into a pair of differently colored areas separated from
each other by a substantially S-shaped line with said areas having
the same size and configuration but being inverted, one with
respect to the other, said transparent disc being clear except for
one portion which has a configuration and size which is the same as
that of one of said areas of said face and which is of a
transparent color different from those of said areas of said face
so that during rotary movement of said disc it will coact with said
face to provide the appearance of areas of ellipsoidal
configuration which are constantly increasing and decreasing in
size.
Description
BACKGROUND OF THE INVENTION
The present invention relates to timepieces.
In particular, the present invention relates to timepieces such as
clocks or watches which, in addition to telling time, are capable
of providing pleasant visual effects.
Timepieces are known where the movement of components of the
timepiece are used for special purposes. For example, it is known
to provide a timepiece with rotary components which differ sharply
from conventional hands and numerals of a clock or watch and which
are designed to tell time in a very special way. Thus, with a
construction of this type, it is indeed possible to achieve a
special visual effect, but not only has the timepiece lost its
conventional time-indicating function, in addition it becomes
necessary for the owner of the timepiece to learn how the timepiece
operates to tell time with the special visual effects, so that
before the timepiece can make any sense, it is necessary to
determine the significance of the positions of the movable
components of the timepiece which are visible at the exterior
thereof.
SUMMARY OF THE INVENTION
It is a primary object of the present invention to provide a
timepiece of this general type which not only is capable of
achieving special visual effects but which, in addition, will
maintain its normal time-indicating function, so that the owner of
the timepiece can tell time in the conventional way and need not
learn special time-interpreting techniques to be applied to the
special visual effects.
Also, it is an object of the invention to provide a timepiece which
can achieve these results with an exceedingly simple structure
which does not increase the cost of the entire timepiece
undesirably.
Furthermore, it is an object of the invention to provide a
construction which will retain the conventional structure of a
timepiece, requiring only that components of the invention be added
thereto without in any way changing the conventional timepiece
components.
Furthermore, it is an object of the invention to provide a
construction which lends itself to achievement of a wide variety of
different types of visual effects which are pleasant to view and
which at the same time give the timepiece an interest which would
otherwise be lacking.
According to the invention, the timepiece has a pair of
time-indicating hands, namely, an hour hand and a minute hand,
which operate in a conventional way to indicate the time, in
combination with a series of numerals arranged around a circle, as
is well known. These hands of the timepiece of the invention are
situated in front of a stationary face of the timepiece. However,
instead of a sweep-second hand, there is situated in front of the
hands of the timepiece a transparent sweep-second disc which is
connected to the mechanism normally used for turning the
sweep-second hand in the same way as the latter, so that with the
structure of the invention it is a disc which is rotated instead of
a hand. This transparent disc as well as the face which is visible
therethrough and which is situated behind the hands are both
provided with designs of predetermined colors and patterns which
coact during rotary movement of the disc to achieve very special
effects such as the appearance of areas of given configuration the
size of which constantly increases and decreases.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to the drawings, FIG. 1 shows a timepiece 10 in the
form of a watch having a usual bezel 12 and capable of being wound
or having the hands thereof set by way of a crown wheel 14, all of
which is conventional.
The timepiece includes an hour hand 16 and a minute hand 18. Around
the bezel 12 there is an annular area 20 carrying numerals for
indicating the hours and for coacting with the hands 16 and 18 to
tell the time in a normal, conventional manner.
Referring to FIGS. 2 and 4, in the timepiece 10 there is situated
behind the hands 16 and 18 a stationary face 22 forming the front
surface of a stationary circular plate 24. This face 22 in the
illustrated example has a pair of areas 26 and 28 of different
colors such as red and yellow, for example, with these areas
separated from each other by the S-shaped line 30. Thus, it will be
seen that the configuration and size of the areas 26 and 28 are
identical, these areas only being inverted, one with respect to the
other, and extending along the common boundary 30 therebetween.
The entire plate 24 with the stationary face 22 is enclosed within
a suitable transparent cover 32 made of glass or plastic. Behind
this clear glass or plastic crystal-type of cover 32 is a
sweep-second disc 34. This disc 34 is connected to that part of the
movement which is normally used to rotate the sweep-second hand.
Thus, instead of a sweep-second hand, the timepiece includes a
sweep-second disc 34 which makes one complete revolution each
minute. The mechanism may be such that the disc carries out a
stepwise movement by increments of one second or it may
continuously sweep around completing the one revolution in one
minute.
As is apparent from FIG. 3, the disc 34 is divided into a pair of
areas which are identical to the areas 26 and 28 in shape and size.
However, the area 36 is clear and transparent while the area 38 is
transparent but of a different color such as a transparent blue or
purple color.
Thus, with this construction, when the watch is running, the
sweep-second disc 34 rotates through one revolution each minute,
and the curved portion of the area 38 coacts with the areas 26 and
28 to achieve effects such as ellipsoidal areas which are
continuously increasing and decreasing in size, so that an
exceedingly pleasant, very special visual effect is achieved with
this construction.
At the same time, the hands 16 and 18 are clearly visible through
the disc 34 so that the time-indicating function of the timepiece
is maintained.
In the timepiece 40 which is indicated in FIGS. 5--9, the hands 16
and 18 are the same as the hands 16 and 18 of FIG. 1, and the
components 12 and 14 are also identical, so that the same reference
characters are used. However, in this case, the stationary face 42
behind the hands is shown in FIG. 7 as divided into sector-shaped
areas each extending through an angle of 120.degree. with these
areas being of different colors. The sweep-second disc 44 shown in
FIG. 6 is made up of identical areas but of different colors, and
this disc is of course, transparent so the hands 16 and 18 are
still visible. Thus, with this construction, the disc 44 will
continuously rotate, completing one revolution each minute, and it
can rotate from a position such as that shown in FIG. 5 where it
has the same position as that of FIG. 6 to a position such as that
shown in FIG. 8 where it has turned to 180.degree. and through the
position of FIG. 9 where it has turned through 300.degree. beyond
the position of FIG. 5. It is to be noted that when the position of
FIG. 8 is reached, the areas on the disc 44 match those on the
stationary face 42 so that the appearance of three sector-shaped
areas of equal magnitudes is given. However, in the position of
FIG. 5, it will be noted that the patterns coact to provide an
impression of smaller sector-shaped areas because of the manner in
which the different colors overlap. In FIG. 9 the areas are of the
same size but a completely different color effect is achieved.
Thus, with the invention, differences in color as well as size and
shape are achieved during rotation of the transparent sweep-second
disc.
