Claims
What is claimed is:
1. An alarm wrist watch having a band, a watch case and an
electro-acoustical signal transmitter which can be triggered by the
watch movement at pre-selectable signalling time points, the
improvement comprising arranging the electro-acoustical signal
transmitter directly at a part of the band removed from the watch
case, said part of the band at which there is arranged said
electro-acoustical signal transmitter being connected with the
watch case by a flexible section of the band, so that when the
alarm wrist watch is worn by a user the watch case and
electro-acoustical signal transmitter are automatically located at
considerably spaced peripheral locations about the wrist of the
user, to thus provide increased sensitivity of the user to response
of the electro-acoustical signal transmitter.
2. The alarm wrist watch as defined in claim 1, wherein the band
incorporates a closure portion located substantially diametrically
opposite the watch case, said signal transmitter being arranged at
the closure portion.
3. The alarm wrist watch as defined in claim 2, further including a
current source for powering the signal transmitter, said current
source being arranged at the closure portion of the band.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a new and improved construction of
alarm wrist watch having a wrist watch band, a watch case or
housing and an electro-acoustical signal transmitter which can be
triggered by the watch movement at pre-selectable signalling times
or time points.
The development of miniaturized electro-acoustical signal
transmitters has been responsible for the advent of such alarm
wrist watches. The known wrist watches of this type, however,
possess the appearance and dimensions of a more sporty-type watch,
that is to say, more like a rather bulky or non-flat wrist watch
for men possessing a relatively large diameter. This dimensional
size of the watch is predicated upon the multiplicity of different
groups of elements which must be accommodated at the common watch
case or housing. These elements or components can be enumerated,
for instance, as the actual watch movement, the signal transmitter,
the current source and a switch for selectively switching-in and
switching-out the signal transmitter.
Apart from the fact that owing to this multiplicity of groups of
structural elements the minimum size, and especially the minimum
thickness of the watch, cannot be reduced below a size which is
much greater than that required for other wrist watches, such
multiplicity of groups of structural elements further requires a
particularly complicated shaped watch case or housing and generally
also the use of a special watch movement.
The complicated configuration of the known watch cases of watches
of the aforementioned general character, apart from the actual
number of different groups of structural elements, is also
attributable to the fact that such structural element groups each
require a respectively different maintenance. While the watch
movement or clockwork is constituted by a group of components
having fairly great as possible longevity, and must be placed in
the hands of a skilled watchmaker for servicing or the like, the
current source and also the signal transmitter and switch
constitute structures of less longevity which should be easily
accessible so that, if necessary, even the user of the watch has
the possibility of carrying out ready replacement thereof.
On the other hand, with conventional battery-operated wrist
watches, that is to say, those without any signal transmitter, for
instance of the type known from Swiss Pat. No. 348,661, German
petty Pat. No. 1,827,392 and French Pat. No. 1,205,272, it has
already been proposed, owing to a certain lack of space in the
watch case or housing, to remove the battery and a part of the
electrical circuit belonging to the electrical movement out of the
watch case, so that such can be designed more delicately and
aesthetically. Thus, it is already known in the art to arrange
externally of the watch case movement-powering components (and not
components controlled by the movement).
Accordingly, it would be also basically conceivable to employ the
same measures for the same purpose with an alarm wrist watch of the
previously mentioned type, without however dislodging the
electro-acoustical transducer from the watch case because thereby
the watch case itself would have to be surrendered as the resonance
box and along therewith there would be reduced the acoustical
efficiency of the signal transmitter.
SUMMARY OF THE INVENTION
Hence, with the foregoing background of the state-of-the-art in
mind it is a primary object of the present invention to provide an
improved construction of alarm wrist watch of the previously
mentioned type wherein it is not only possible to considerably
reduce in size the watch case in comparison with the known alarm
wrist watches, but also to considerably increase the awareness of
the user to the electro-acoustical signal transmitter by means of
the human sensatory organs, something which is important for an
alarm type watch piece.
A further significant object of the present invention relates to a
new and improved construction of alarm wrist watch which contains a
novel arrangement of the components of the wrist watch to allow for
a relatively small dimensional size of the watch in comparison to
the prior art alarm wrist watches, and therefore to render same
more attractive and pleasing to the eye.
Now in order to implement these and still further objects of the
invention, which will become more readily apparent as the
description proceeds, the alarm wrist watch proposed by this
development is manifested by the features that the
electro-acoustical signal transmitter is arranged at a portion of
the watch band removed or remote from the watch case.
In this way there is not only realized the primary aimed for
reduction in the external dimensions of the watch case, but beyond
such there is also realized an effect as concerns the alarm aspects
of the watch which is no way rendered obvious by any of the
heretofore known watches and more than compensates for the already
mentioned reduction in the acoustical efficiency of the signal
transmitter. As is well known wrist watches are generally worn in a
manner where the watch case with the dial comes to bear at the side
of the wrist facing away from the body of the user. At this side of
the user's wrist the sense of touch is less well defined than at
the remaining portions of the wrist. Furthermore, as a general rule
most people adjust themselves so rapidly to wearing a wrist watch
that, even after a short period of time, the wearer is no longer
conscious of the presence of the wrist watch, especially the larger
weight of the watch casing with the watch movement. The sense of
touch therefore becomes even less delicate exactly at the side of
the wrist facing away from the body.
On the other hand, it should be readily apparent that the noise
output of electro-acoustical signal tranmitters which are suitably
miniaturized for such wrist watches is not unlimited, especially if
they are arranged externally of a hollow compartment or cavity
serving as a resonance box. Such signal transmitter is therefore,
by its very nature,not always capable of exceeding the random
sounds of the surroundings which may be present at any given
time.
Now if the electro-acoustical transducer is left in the watch case,
then owing to the resonance action with the housing, there is
indeed attained a somewhat greater noise output of the signal
transmitter. But where the user of the watch is hard of hearing, or
in a situation where there is present a high surrounding noise
level, then there exists the danger that the acoustical signal of
the signal transmitter will not reach with sufficient intensity the
wearer's hearing and be perceived by him. This is even much more
the case because for most of the carrying locations of the wrist
watch which generally arise during use the signal transmitter in
most positions of the lower arm of the wearer is located at the
side of the wrist which faces away from the ear of the wearer, so
that the primary direction of propagation of the sound waves occurs
away from the wearer's ear. The acoustical output or efficiency of
the signal transmitter might very well be quite high, but in
practice it cannot be fully utilized, that is to say, the signal
transmitter possesses an insufficient output as concerns the user
perceiving the same.
Now with the watch construction of this development these drawbacks
and risks which are prevalent with the known alarm wrist watches
are extensively eliminated. During wearing of the watch the
electro-acoustical signal transmitter is not located at that region
of the wrist where by virtue of the presence of the heaviest part
of the watch (watch case with watch movement) the sense of touch of
the user has been deadened or diminished by becoming accustomed to
wearing the watch, rather is present at a location where the touch
sensitivity is considerably greater and additionally confronts the
ear of the wearer. Consequently, the sound waves, even if they do
not reach the hearing of the wearer with sufficient intensity
nonetheless will be noticed, by virtue of this more sensitive
location or point of the wrist, directly in the form of
oscillations, approximately comparable to the fluttering of the
wings of an insect.
If as the movement for the watch there is provided a spring
mechanism, whether such is equipped with a manual winder or
automatic winding, then advantageously also the battery, for
instance a small disc or button battery cell, and the switch of the
signal transmitter can be arranged at a part of the wrist watch
band. Hence, there only remains in the watch case those groups of
components which require servicing by a trained watchmaker, whereas
the components which also can be exchanged by unskilled individuals
are accommodated at the band of the wrist watch.
This arrangement brings with it a further advantage: Only two
electrical conductors need be conducted away out of the timer or
time piece (apart from the adjustment-and possibly the winding
crown). Moreover, the watch case or housing can be completely
accommodated to the raw or blank material and can be designed as
delicate and flat as such permits this to happen, so that there are
not required any special constructional measures in order to render
the watch casing waterproof. Hence, the watch movement has imparted
thereto the required protection without having to resort to any
special constructional expenditure, and the casing remains
relatively simple in construction, whereas the watch band offers
space for the components which of necessity must be exchanged from
time to time.
Finally, the last-mentioned arrangement also renders it possible to
construct a ladies wrist watch or a chronograph with an alarm
mechanism, practically without having to enlarge the external
dimensions of the watch itself in comparison to simple ladies'
watches and chronographs.
BRIEF DESCRIPTION OF THE DRAWING
The invention will be better understood and objects other than
those set forth above, will become apparent when consideration is
given to the following detailed description thereof. Such
description makes reference to the annexed drawing wherein the
single FIGURE illustrates an exemplary embodiment of inventive
alarm wrist watch.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Describing now the drawing, reference numeral 1 designates a
conventional watch wherein, however, the setting or adjustment hand
2 is rigidly connected for rotation with a contact disk 40 arranged
beneath the watch dial 3. The contact disk 40 is electrically
connected with a conductor 5 which leads from internally of the
casing or housing 9 to one of the pair of lugs or projections 11
for receiving therebetween the watch band, and specifically into
the one bore for the associated spring pin 6. The contact disk 40
is moreover insulated with the exception of a small contact segment
41. Further details regarding a contact arrangement usable for this
purpose are disclosed, for instance, in Swiss Pat. No. 487,454 or
in the corresponding U.S. Pat. No. 3,611,702, to which reference
may be readily had. The conductor 5 is therefore guided to such
contact segment 41 and such possesses a rotational position
determined by the setting hand 2. Consequently, the spring pin 6,
which hingedly connects the part or strap 8 of the wrist watch band
with the wrist watch 1, is electrically connected with the contact
segment 41. Leading from the spring pin 6 is a conductor 7 which is
completely embedded at the strap part 8 of the wrist watch band,
this conductor 7 leading to a spring pin 17, which, in turn,
hingedly connects the strap part 8 of the band with the buckle or
closure part 20 of the band.
In the exemplary embodiment under consideration the wrist watch is
provided with an "endless" band which can be shortened by means of
a so-called conventional strapping or tightening buckle or clasp in
order to be fixedly tightened about the wrist of the user.
The hour indicator 12 is electrically and rigidly connected for
rotation with a contact arm 4 which wipingly moves across the
contact disk 40 below the dial 3. Additionally, the hour indicator
12 is connected with a conductor 13 which, in turn is led from
internally of the case or housing 9 of the watch 1 to the spring
pin bore of the other band lug pair 11. The hour indicator 12 also
can be electrically connected with a dial consisting of conductive
material, in which case the conductor would then first be connected
to such dial. At the band lug or bracket pair 11 a spring pin 14 is
in conductive connection with the conductor 13 on the one hand and
with a conductor 16 on the other hand, conductor 16 being embedded
at the part or strap portion 15 of the band. The conductor 16 is
furthermore connected to an additional spring pin 23 which connects
the closure or clasp portion 20 pivotably with the part 15 of the
band.
At the buckle portion 20 a conductor 18 leads from the spring pin
17 to a switch 19 which can be actuated by means of a knob or
button 25. The other connection or terminal of the switch 19 is
coupled with a miniaturized buzzer 21 defining the
electro-acoustical signal transmitter, for instance of the type
disclosed in Swiss Pat. No. 497,760, the other connection or
terminal of which is coupled with a battery 22, for instance a
conventional disk cell of the type used for hearing aids. The other
pole of the battery 22 is coupled through the agency of a conductor
24 embedded at the closure or clasp portion 20 with the spring pin
23 which, as mentioned, is connected via the conductor 16 with the
hour indicator or hand 12 and the contact arm 4 respectively.
As long as the switch 19 is closed the buzzer 21 is thus
switched-in, as soon as its power supply circuit is closed via the
closed switch 19- conductor 18- spring pin 17- conductor 7- spring
pin 6- conductor 5- contact segment 41- contact arm 4- conductor 13
or dial respectively- spring pin 14- conductor 16- spring pin 23-
conductor 24 and battery 22. This is then the case when the hour
indicator or hand 12 has reached the signalling time point
determined by the adjustment or setting indicator 2 according to
its setting. In order to shut-off the buzzer or acoustical
generator 21 it is sufficient to actuate the switch 19.
The advantages of the described watch should be self-evident. The
watch movement, which can be a standard movement and need only be
amplified by the contact arm 4, the setting indicator 2 as well as
the contact disk 41 and the conductor 5 as well as possibly
conductor 13, is accommodated in a casing 9 which extensively
corresponds to the standard dimensions, in other words a flat
casing or housing 9. Without any particular constructional
expenditure such can be readily rendered waterproof. The components
of less longevity, namely the battery 22, the buzzer 21 and the
switch 19 are arranged at the closure or clasp portion 20 and at
that location easily accessible, without having to open the casing
9 of the watch. Even if the band closure portion 20 with the
therein mounted group of components should become defective, for
instance owing to damaging same through improper handling, then the
watch 1 itself still remains completely functional.
In the event that the watch case 9 is formed of metal, that is
electrically conductive, and likewise the arm band 8, 15, then it
is only necessary to lead a conductor in insulated fashion to the
buckle or closure portion 20. In this case the arm band and the
casing provide a return flow path for the current. On the other
hand, if there is provided an arm band with a belt buckle or prong
type closure, then, both conductors 7, 16 can be embedded in the
same band section in order to maintain the watch fully functional,
for instance as an alarm watch, when such is also placed in a flat
or laid out condition.
Even exchange of the arm band does not present any particular
difficulties, since the use of spring pins is almost the general
rule for wrist watches. Care only need be taken to ensure that, for
instance, with the embodiment under consideration the spring pin 14
is connected with the spring pin 23 and the spring pin 17 with the
spring pin 6.
The development of this invention is also particularly advantageous
if it is designed, as already mentioned as a wrist chronograph or a
ladies' wrist watch. Generally, certain maximum external dimensions
should not be exceeded with a wrist watch so that its practical
handling can be ensured. Especially in the case of chronographs
particularly with automatic winding, with their second- as well as
possibly minute- and hour indicators driven by the same movement,
however over separate transmissions as well as equipped with
resetting mechanisms with knobs, the above-mentioned maximum
external dimensions in any case already presents quite considerable
difficulties to those skilled in the art to sensibly accommodate
all of the mechanisms in a casing or housing which still possesses
sufficient aesthetic appeal. Similar considerations are applicable
in the case of ladies' watches where generally there is strived for
as extensive as possible delicateness of the watch. Only by means
of the development of this application is there rendered possible,
for instance, the production of a ladies watch, with electrically
operated signal transmitter, without diminishing the delicacy of a
watch which is without a signal transmitter.
While there is shown and described present preferred embodiments of
the invention, it is to be distinctly understood that the invention
is not limited thereto, but may be otherwise variously embodied and
practiced within the scope of the following claims.
