BACKGROUND
Field of the disclosure
[0001] The present application relates to snapping and hinging arrangements. More particularly,
the present application is directed to snapping and hinging arrangements to be used
in fastenable articles, and their associated construction and uses. The present application
or disclosure also relates to watches and arrangements, uses and methods associated
therewith.
Description of the background art
[0002] When using a fastenable article, it is often desirable to use fastening means which
are easy and simple to use. This is particularly true when the fastenable articles
are clothing items, such as shoes, belts, phone holders and time pieces.
[0003] With reference to the latter case, for example, watches have been typically provided
with various buckle-type fastening means in order to fasten portions of the band together
and thus secure the timepiece to a wearer's wrist, for example. While this method
is sufficient to secure timepieces to a wrist, the intricacies involved in using a
buckle/clasp-type of fastening mechanism may prove to be too difficult/complex to
operate without encountering difficulty and frustration, especially for young children
or persons with limited manual dexterity.
[0004] Generally the concept of time is also often difficult and complex for children to
comprehend.
[0005] A configuration that provides secure fastening and ease of operation, both for fastening
and unfastening, as well as a method to teach children how to tell the time and to
relate time to various daily events, is clearly needed.
[0006] Also, in the case of wristwatches, it is sometimes desirable to transfer the watch
from one band to another, for example, to use a band that better coordinates with
other fashion items. However, most existing mechanisms used to attach watches to watchbands
use very small pins, making the band difficult and time consuming to remove and install.
Hence, there is a need for an improved attachment mechanism that provides for quick
and easy removal and installation of different watchbands on a wristwatch. An example
of a watch assembly having a housing and a spring element is known from
GB2112549
[0007] Furthermore, other fashion items, such as pins and broaches are typically attached
to clothing and other items using pins, and other mechanisms, that are awkward and
difficult to use. The pins can also damage the fabric through which it is inserted.
There is need for an improved attachment mechanism for pins and broaches that is easy
to use and does not damage the fabric of the item to which it is attached.
SUMMARY OF THE DISCLOSURE
[0008] The present disclosure relates to a snapping arrangement and a hinging arrangement
to be used in connection with items. In particular, the disclosure relates to a snapping
arrangement to be applied on a strap.
[0009] The strap can be used for fastening clothing items such as shoes, belts, phone holders
etc. One embodiment refers to time measuring devices, such as watches. With reference
to watches, the snapping mechanism allows the strap to be secured on a portion of
the human body, such as the wrist or the ankle.
[0010] The snapping mechanism utilizes cooperation of two assemblies on the strap, a magnet
assembly and a metal assembly. The magnet assembly is located proximate to or at one
end of the strap. The metal assembly is located proximate to or at the other end of
the strap. During use, the magnet assembly is secured to the metal assembly. The magnet
assembly becomes secured to the metal assembly through a snap action, where contact
between the magnet assembly and the metal assembly is achieved at least in part by
means of a magnetic engagement between the magnet assembly and the metal assembly.

DETAILED DESCRIPTION OF THE DISCLOSURE
[0057] A snapping arrangement is initially disclosed. The arrangement comprises a strap
and two cooperating assemblies on the strap, a magnet assembly and a metal assembly.
The magnet assembly is located proximate to or at one end of the strap. The metal
assembly is located proximate to or at the other end of the strap. During use of the
strap, for example on the wrist or ankle of a user, the magnet assembly is secured
to the metal assembly. The magnet assembly becomes secured to the metal assembly through
a snap action, where contact between the magnet assembly and the metal assembly is
achieved at least in part by means of a magnetic engagement between the magnet assembly
and the metal assembly.
[0058] Several embodiments are shown in the present disclosure exhibiting different shapes
and functions of the magnet/metal assemblies.
1. Magnet assembly
[0059] Figures 1-3 show a first embodiment of a magnet assembly (1) on a strap (2), comprising an upper
portion (3) and a lower portion (4). The upper portion (3) is usually button-shaped
and does not need to be magnetic. For example, it can be made of plastic. The lower
portion (4) is magnetic and can be cylindrical in shape.
[0060] The lower portion (4) can be connected with the upper portion (3) in a variety of
ways.
[0061] For example, the upper portion (3) can have an element protruding from its bottom
surface and engaging with a recess in the upper surface of the lower portion (4).
To this effect, a hole will be formed in the strap (2), near a tip (5) of the strap.
Therefore, the upper portion (3) and the lower magnetic portion (4) pop into place
and engage one another, thus forming the magnetic assembly.
[0062] Figures 4-5 show in more detail an upper surface (6) and a lower surface (7) of the strap. With
reference to those figures, and alternatively to what is disclosed above, the upper
portion (3) of the magnet assembly can be glued together with the upper surface (6)
of the strap, and the lower magnetic portion (4) of the magnet assembly can be glued
together with the lower surface (7) of the strap. Figure 5 also shows a rib (8), which
could be added to the magnetic assembly to increase stability of the assembly on the
strap. A further kind of connection between the upper portion (3) and the lower magnetic
portion (4) is a "press fit" connection, where the upper portion (3), the portion
of the strap (2) close to the tip (5), and the lower magnetic portion (4) are kept
into place by means of pressure forces.
[0063] Figures 6-7 show a second embodiment of the magnet assembly on the strap (2), comprising a cap
(9), enclosing both the upper portion (3) and the lower magnetic portion (4). The
cap (9) forms a space (not shown), between the upper portion (3) and the lower magnetic
portion (4), for an end portion of the strap (2) to be inserted before the components
of the magnet assembly are snapped into place. Also in this case, a hole will be formed
in the strap (2).
[0064] It should be noted that the presence of the cap (9) under the upper portion (3) and
above the strap (2) on the non-magnetic side of the magnet assembly provides a pleasant
aesthetic, mushroom-like aspect. Additionally, stability of the end portion of the
strap is improved. Alternatively the cap itself could also provide a tip of the strap,
thus not requiring the strap to be placed in the middle of the cap. Connection between
the cap/tip and the strap (2) can be achieved by mechanical means, such as screws
(10,11) as schematically shown in Figure 7.
[0065] Alternatively to what is shown in
Figures 6 and 7, the cap (9) can be provided instead of (and not in addition to) the upper portion
(3). In this case, the aesthetic effect due to the presence of the upper portion can
be obtained by suitable reshaping of the cap element (9).
[0066] Figures 8-12 show a third embodiment of the magnet assembly on the strap (2), where cap (9) also
acts as upper portion. In this embodiment, the lower magnetic portion of the magnet
assembly is provided by an arc- or bean-shaped element (13). The shape of the element
(13) is better shown in perspective in the enlargement of
Figure 10. Figures 11 and 12 are partial cross sections better showing some of the details of the third embodiment.
In particular, the cap (9) comprises a recessed area (14) on its top. Additionally,
a retention pin (15), preferably a metal retention pin, is provided to connect the
strap (2) with the cap (9). In this way the whole assembly, including lower magnetic
portion (13), is kept in place by means of mechanical forces. If desired, an upper
portion, as shown in the previous
Figures 1-4, can be provided in place of the recessed area (14). It should be noted that the
connection between the upper portion and the lower magnetic portion (12) can be obtained
in a variety of ways, easily determinable by the person skilled in the art upon reading
of the present disclosure. For example, the arc-shaped portion could be press-fit
into the cap portion, or partially recessed into the cap portion.
2. Metal assembly
[0067] The metal assembly is located on an end of the strap (2) opposite the end on which
the magnet assembly is located. In this way, when the strap (2) is closed, in a circular
fashion, one assembly will mate with the other.
[0068] Figures 13-16 show a first embodiment of a metal assembly on the strap (2). The metal assembly
comprises a plurality of rivets (16), each having a top or mating surface (17) and
a bottom or engaging surface (18), as shown in the exploded view of
Figure 15. Each rivet (16) engages into a corresponding metal element (19) by means of its
engaging surface (18), as also shown in the exploded view of
Figure 15. The metal elements (19) are located on the lower surface (7) of the strap (2), proximal
to the skin of the user. The rivets (16) are located on the upper surface (6) of the
strap (2), distal to the skin of the user, during use. The substantially circular
shape of the mating surfaces (17) corresponds to the substantially circular shape
of the bottom surface of the lower magnetic portion (4) of the magnet assembly, shown
in some of the previous Figures. Magnetic engagement of the bottom surface of the
lower magnetic portion (4) with one of the mating surfaces (17), one of the mating
surfaces (17) being chosen among the others in accordance with the desires or size
of the wrist or ankle of the user, allows closure of the strap (2). Of course, stability
of the closure of the strap (2) is maximized when there is geometric correspondence
between the bottom surface of the lower magnetic portion (4) of the magnet assembly
and the mating surface (17). However, geometric correspondence between the mating
surfaces is just a preferred embodiment, and not a necessary feature of the present
disclosure. Additionally, the person skilled in the art will recognize, upon reading
of the present disclosure, many geometric alternative shapes, such as square, rectangular,
triangular, hexagonal, etc. shapes, both for the bottom surface of the lower magnetic
portion (4) of the magnet assembly and the mating surface (17), are possible.
[0069] Pressed rivet technology, preferably used to realize the assembly of
Figures 13-16, is known to the person skilled in the art and does not need to be described in detail.
For example, an overmolding process could be used, i.e. the strap (2) is first molded
and then the rivets (16) and metal elements (19) are molded into the strap (2), on
opposite surfaces (6, 7) thereof.
[0070] Figures 17-20 show different shapes of the rivets and metal elements. For example, the shape of
the mating surfaces of Figure 17 is suitable for use with the lower magnetic portion
(13) shown in Figure 10. Spacing between the rivets (16) determines the number of
rivets and consequently, the number of different sizes of the strap (2). In case the
shape of the rivets (16) is such that the mating portion (17) is circular, spacing
between the rivets (16) cannot be less than the diameter of the rivets (16), thus
reducing the available design choices. For example, spacing between the rivets (16)
in these embodiments is usually about 10 mm (about .4"). However, it should be noted
that an arc- or bean- shape allows a better stability of the metal elements (19) when
pressed into the strap. In particular, arc/bean-shaped metal elements have less tendency
to pivot than circularly-shaped metal elements. Additionally, the presence of arc/bean
shaped metal elements instead of circular elements allows for tighter spacing between
the rivets (16), thus permitting a higher number of different sizes to be provided
on the strap (2).
[0071] The metal assembly structure can be reinforced by means of a rib or spine structure
(20) placed in the strap (2) and mechanically connecting the various elements of the
metal assembly, as shown, for example, in
Figure 19. The presence of a reinforcing structure provides for a better stability of the assembly
and helps avoid undesired pivoting movement of the rivets and metal elements during
use of the strap (2). According to a first aspect (not shown in the Figures), the
rib structure could be additional to, or independent from, the plurality of rivets
(16) and metal elements (19), to be placed, for example, between the rivets (16) and
the metal elements (19), and comprising a plurality of holes in correspondence with
the junction between each metal element and its corresponding rivet.
[0072] Figures 21-22 show a partial cross sectional view and a partial perspective view, respectively,
of a second embodiment (21) of the rib structure, where the rib structure (21) is
integral with the plurality of metal elements. Therefore, according to this second
embodiment as shown in detail in
Figure 22, the integral rib structure (21) comprises a spine portion (22) comprising a plurality
of holes (23) and a plurality of mating metal portions, each having a first side (24A)
and a second side (24B), placed in correspondence with a hole (23) and having a shape
matingly corresponding to the shape of a lower magnetic portion (4) of the magnet
assembly (1).
[0073] According to a further embodiment of the metal assembly in accordance with the teachings
of the present disclosure, the metal-element/rivet combination is replaced by a plurality
of staple elements.
Figure 23 is a cross-sectional view and shows one of the staple elements (25) inserted into
corresponding openings or slots (26) of the strap (2). In particular, the strap (2)
is provided with two slots (26) for each of the staple elements (25) to be placed.
[0074] Figures 24A-24C show the various shapes of each staple element (25) during a manufacturing process.
During the manufacturing process, each staple element initially exhibits a first stamped
and tumbled condition (A),
Figure 24A, with an arcuated, for example substantially semi-circular, shape, having an outer
periphery (27), an inner periphery (28), and two lateral ends (29, 30). The staple
undergoes a first bending operation,
Figure 24B, and is bent along its lateral ends (29, 30) to provide a bent condition (B) comprising
an upper, unbent, mating portion (31), a first bent portion (32) and a second bent
portion (33). Further to this, one or more staples are inserted into the strap (2),
as shown in
Figure 25. Each staple is placed or loaded into position by inserting its first and second
bent portions (32, 33) into slots (26) provided in the strap (2) and shown in
Figures 25 and 26. At the end of this step, the mating portions (31) of each loaded staple in its condition
(B) have reached their position in the strap (2). Subsequent to this, the first and
second bent portions (32, 33) are bent or folded again, this time around the strap
(2), to reach a completely folded condition (C), as shown in
Figure 24C, which shows a staple alone for clarity reasons.
Figure 26 shows this last step in more detail, showing the bent portions (32, 33) both in their
(B) condition (32B, 33B) and their (C) condition (32C, 33C).
[0075] As shown in
Figures 23 and 25, the preferred embodiment also provides for a particular structure of the area surrounding
the slots (26) for each staple (25). In particular, for each staple (25), the region
comprising the two slots (26) is recessed and comprises a step-like structure with
two raised or stepped portions (34, 35) and one lower flat portion (36), on which
the staple (25) is to be placed. Each slot (26) is placed in correspondence to the
region between a stepped portion (34, 35) and the flat portion (36). In this way,
a more stable mechanical structure is obtained, and the overall shape also has a more
pleasant aesthetic aspect.
3. The Strap
[0076] The magnetic and metal assembly have been described heretofore with reference to
a strap. However, it should be noted that they could be applied on any arrangement
for which a cooperation between two mating elements is required. Key-holders, wallets,
belts, etc. represent possible, non-limiting examples, of elements on which the assemblies
could cooperate.
[0077] With reference to the strap, such strap could be of any material or shape. Should
printing on the strap be required, a preferred embodiment shown in cross-section of
the strap is shown in
Figure 27 and provides for a smooth convex upper surface (37) of the strap and a smooth concave
lower surface (38) of the strap.
[0078] In a further preferred embodiment, the strap of the disclosure may include a portion
having a shape that matches the shape of the interior surface of a watchcase. Such
portion is preferably substantially centrally located in the strap. In particular
the portion can have a substantially circular or oval shape and may be used with a
hinging assembly later disclosed in the present disclosure. See, for. example, the
embodiments shown in Figures 40 and 45B, below.
4. The watch
[0079] The strap described heretofore can be used to attach clothing items such as shoes,
belts, phone holders etc. In particular, the strap of the present disclosure can be
the band of a watch.
[0080] Figures 28-32C show various watches embodying exemplary snapping arrangements described according
to the present disclosure, and will not be described herein in detail, as theses embodiments
are understandable to the person skilled in the art, in light of the present disclosure.
5. The Hinging Mechanism
[0081] The present disclosure also provides a hinging mechanism to be connected to an item,
such as a watch case. The hinging mechanism allows the watch case to be attached,
for example, to a strap as described above or to other straps and also allows the
watch case to be applied to items unrelated to the watch, such as clothing items.
[0082] The hinging mechanism according to the present disclosure is shown in perspective
in
Figure 37 and may comprise a leaf spring element, as shown in
Figures 33-36, which disclose a multi-step process for forming the leaf spring element.
[0083] Figure 33 shows the leaf spring element (39) after a first annealing and cutting operation.
The leaf spring element can be made of steel. Cutting can be performed by laser cutting,
or any other appropriate cutting operation, as known in the art, and will not be here
described in detail. The leaf spring element (39) of Figure 33 comprises three main
portions: a first lateral portion (40), a second lateral portion (41) and a central
portion (42). The central portion (42) will act as a spring and is located between
the first lateral portion (40) and the second lateral portion (41). The central portion
(42) has a substantially trapezoidal shape, with an upper edge (43) and two slanted
edges (44, 45). Each of the two lateral portions (40, 41) has a substantially rectangular
shape. Preferably, one of the two lateral portions (40, 41) is the mirror image of
the other. A first cut section (46) and a second cut section (47) separate the central
portion (42) from the first and second lateral portions (40, 41), respectively. Preferably
the first and second cut sections (46, 47) are specular to each other. The first cut
section (46) is substantially parallel to the first (44) of the two slanted edges
of the central portion (42). The second cut section (47) is substantially parallel
to the second (45) of the two slanted edges of the central portion (42). In a preferred
embodiment, both cut sections (46, 47) extend only along a part of the slanted edges
(44, 45) of the central portion (42). Each cut section (46, 47) has an upper or distal
end (48, 49) and a lower or proximate end (50, 51). The upper or distal end (48, 49)
of each cut section (46, 47) is formed by a combination of a part of the shape of
the slanted edge (44, 45) of the central portion (42) with one of the first corners
(52, 53) of the first or respectively second lateral portion (40, 41). The lower or
proximate end (50, 51) of each cut section has a circular contour.
[0084] The bottom region (54) of the leaf spring element (39) is an integral combination
of the bottom regions of the central portion (42) and the two lateral portions (40,
41). In particular, the bottom region (54) has a semicircular overall shape, trifurcated
at the top. In other words, the top portion of the bottom region (54) merges with
the lower portions of the central portion (42) and the two lateral portions (40, 41).
More specifically, the lower edge of the central portion (42) completely merges into
the bottom region of the leaf spring element (39), while the lower edge of each of
the lateral portions (40, 41) only partially merges into the bottom region (54) of
the leaf spring element, the remaining portion of each lower edge forming two specular
bottom side edges (55, 56) of the leaf spring element (39).
[0085] A small trapezoidal region (57) is also present, in correspondence with the central
portion of the lower or outer semicircular edge (58) of the bottom region (54). Finally
a protruding slanted leg (59, 60) is formed on the top edge (61, 62) of each of the
lateral portions (40, 41). Each leg (59, 60) ends with a hollow section (63, 64).
The hollow sections (63, 64) will cooperate with a hinge pin, later shown, to allow
engagement of the leaf spring element (39) with a watch case, for example.
[0086] Figure 34 shows the leaf spring element after a bending operation of legs (59, 60). In particular,
only a portion of the legs (59, 60) is bent, so that each leg now comprises a first
leg portion (65, 66) substantially lying on a first plane and a second leg portion
(67, 68), substantially lying on a second plane different from, and preferably substantially
perpendicular to, the first plane. The second plane where the second leg portions
(67,68) lie, is also preferably substantially perpendicular to a plane formed by the
two lateral portions (40, 41). Additionally, the two second leg portions (65, 66)
are substantially parallel to each other, to allow a correct lining up of a hinge
pin, to be later described, once the hinge pin is inserted into the circular hollow
sections (63, 64).
[0087] Figure 35 shows the leaf spring element after a further bending operation, where an upper part
of the central trapezoidal portion (42) is bent towards the plane formed by the second
leg portions (67, 68). Once bending of the central portion (42) is terminated, the
central portion will exhibit a bending along its surface which attenuates as it approaches
the proximity of its lower edge and is maximum in proximity of its upper edge (43).
[0088] A further bending operation (not shown) of the first and second lateral portions
(40,41) may be performed. Once bending of the first and second lateral portions (40,41)
is terminated, each lateral portion will exhibit a bending along its surface which
attenuates as it approaches its lateral side edges (300, 301) and is maximum as it
approaches the central portion.
[0089] Figure 36 shows a further step, where the leaf spring element of
Figure 35 is heat treated. Preferably, before heat treating, teeth are formed, through bending
(not shown) of second corners (303,304) and third corners (305,306) of the first and
second lateral portions (40, 41).
[0090] Figure 37 shows a perspective view of the leaf spring element (39) when connected to a watch
case (69), for example by means of the bent upper edge (43) and a hinge pin (70) placed
through the hollow sections (63, 64) shown in the previous Figures. Figure 37 also
shows teeth (71) on the spring leaf element (39), for example square or rectangular
teeth. The teeth (71) are preferably formed before cutting and bending of the second
and third corners of the lateral portions (40,41). The teeth (71) allow better grasping
of the item which will contact the spring element (39), to be placed, during use,
between the spring element (39) and the watch case (69).
[0091] Figure 38 shows a partial cross sectional view of the arrangement shown in Figure 37, showing,
in better detail the leaf spring element (39), one of the second leg portions (67)
and the hinge pin (70).
[0092] Figure 39 shows one of the possible uses of the hinging assembly, e.g., on a shirt of a user.
[0093] Figure 40 shows a perspective exploded view of a strap (2), with a magnetic assembly (72) and
a metal assembly (73). The two assemblies have already been described with reference
to some of the previous figures. The strap (2) also comprises a central circular recessed
region (74), hosting the watch case (75). Also the watch case (75) is shown in an
exploded view and comprises a lower plate or back plate (76), a casing (77), a crown
(78), a watch surface or dial surface (79), and a lens (80). It will be appreciated
that the structure of the watch case (75) is modular and easily assemblable. In particular,
the lower plate (76) will fit into the recessed region (74), the casing (77) will
be placed above the lower plate (76), the watch surface (79) will fit into the lower
plate (76) and the casing (77) and the lens (80) will be placed above the watch surface
(79). Also shown is an exploded view of the leaf spring element 39 and the hinge pin
70.
[0094] Figures 41 and 42 show cut sectional views of the watch case (75), together with the leaf spring element
(39) and the pin (70).
[0095] A further embodiment of the hinging mechanism of the present disclosure may also
comprise a base element as shown in
Figure 43 to replace the leaf spring element shown in the previous figures.
[0096] Figure 43 shows a top view of a base element (81), i.e. a view of the internal side of the
base element (81). The base element (81) comprises a substantially circular central
portion (82) and two side portions (83, 84) connected with the central portion and
integral therewith. In particular, the central portion (82) exhibits curved edges
(85, 86). The central portion (82) comprises, along its curved edge (85) a hinging
region (87), for example hinging cavities, which allow the base element (81) to be
hingedly connected with the watch case. The central portion (82) further comprises
a recessed region (88) located in proximity of its curved edge (86) to either allow
locking of the base element (81) with the watch case or to provide a recess for the
crown of the watch case.
[0097] The edges of the side portions (83,84) may be bent to allow a better grasping of
the item to be hosted in the hinging assembly (81).
[0098] The base element (81) may also comprise a path-providing region (203) allowing an
item, such as a watch band, to be inserted. In particular, the region (203) can be
a recessed region and include slightly raised edges. Preferably the shape of the region
(203) matches the shape of the watchband to be hosted.
[0099] Figure 44A and Figure 44B show two different embodiments of the hinging assemblies comprising a base element.
In the embodiment of
Figure 44A, the base element (81) is flat. In the embodiment of
Figure 44B the base element is slightly concave. In particular,
Figure 44A shows a hinging assembly (89) comprising the base element (81) connected with a watch
case (90) by means of a hinge-pin (91) positioned in the hinging region (87). The
hinge-pin (91) can be a spring-hinge. The watch case (90) has an external side (92)
visible during normal use of the watch and an internal side (93) not visible during
normal use of the watch. The internal side (93) has an overall peripheral shape substantially
matching the peripheral shape of the base element (81). The internal side (93) allows
the crown (94) to come into engageable connection with the recessed region (88) of
the base element (81), for example after a watch band is inserted between the watch
case (90) and the base element (81), as shown in the following figures.
[0100] The internal side (93) of the watch case (90) also differs from the base element
(81) in that it comprises a region (95), for example a substantially rectangular region
(95) centrally disposed. The region (95) has slightly raised edges in order to better
allow the watch band to be inserted within the assembly (89). The region (95) could
also be slightly recessed with respect to the remaining part of the internal side
(93). Te region (95) substantially corresponds to the region (203) of the base element
(81) previously discussed in
Figure 43. Region (95) may have different shapes matching the shape of the item to be inserted
in the hinging assembly. When the item is a strap including a substantially oval portion
matching the oval shape of a watchcase, the region (95) has preferably a substantially
oval shape.
[0101] Figure 44B shows a further embodiment of the hinging assembly (89), wherein the watch case (90)
does not include a region such as region (95) of
Figure 44A and the base element (81) includes the region (203) already described with reference
to
Figure 43. In this embodiment, the region (203) is recessed with respect to the remaining part
of the internal side of the base element (81), has a substantially oval shape, and
no slightly raised edges. The side portions (83,84) are bent along upper edges (204,205)
and lower edges (206,207) to allow a better grasping of the watch band to be hosted
in the region (203).
[0102] Figures 45A and 45B show the hinging assembly (89) in an open condition hosting a watch band (96).
Figure 45A shows a first embodiment, where the hinging assembly according to the embodiment
of
Figure 44A is employed, and where the watch band (96) is a strap having a substantially rectangular
portion in the portion matching with region (95).
Figure 45B shows a further embodiment, where a hinging assembly substantially similar to the
hinging assembly according to the embodiment of
Figure 44B is employed, and where the watch band is a strap having a central substantially oval
portion (201). The oval portion (201) matches with an oval embodiment (202) of the
region (95). The oval portion (201) lies on the region (203) in the base element.
[0103] Figures 46 and 47, show other uses of the hinging assembly (89), where the overall shape of the watch
band is different from the shape of the watch band (96) of Figure 45 or where supports
different from a watch band are used, such as the support (97) of Figure 47. The support
(97) also shows an upper hollow region (98) to allow the support to be attached to
other items. The portion of support (97) hosted in the hinging assembly may have other
shapes, in particular a substantially circular oval shape matching the shape of the
region (95) in the watchcase and/or region (203) in the base element.
[0104] The person skilled in the art will understand, upon reading of the present disclosure,
that the base element (81) of Figures 43-45 can be replaced by the leaf spring element
exemplarily shown in Figures 33-37. On the other hand, the person skilled in the art
will also understand, upon reading of the present disclosure, that the leaf spring
element, such as the leaf spring element of Figure 27, can be replaced by the base
element (81) exemplarily shown in Figure 43-45.
[0105] Both the hinge mechanism used to hingedly connect the elements of the hinging assembly
of the disclosure and the locking mechanism used to secure the elements of the hinging
assembly of the disclosure are known as such to the person skilled in the art and
will not be described in detail.
6. System and method to teach how to tell time
[0106] The present disclosure also provides a watch system and method to teach a user how
to tell the time, particularly useful for users having difficulties in learning the
concept of time, such as children and persons with learning disabilities.
[0107] The watch system includes a first display showing the time in an analog or digital
manner and a second display showing indication of an event associated with the time
shown by the first display. The configuration and dimensions of the first and second
display may vary and differ in complexity. The system may also emit sounds accompanied
with the indications shown by means of a sound-emitting assembly.
[0108] Figure 48 and the enlarged portion of Figure 48 shown in
Figure 49 show a "first level" system where the first display (99) shows a plurality of hour
hands (150) and the second display (100) shows a picture or icon that relates to a
specific time of day, e.g., sun rising, snack time, nap time, play time, bed time,
moon. The picture or icon shown on the second display (100) relates to events in a
child's day that are events/milestones in the child's day, thus helping the child
to grasp time by tying it to such events/milestones. Preferably, the system is assembled
according to one of the embodiments previously discussed. When the second display
(100) shows a specific icon, such as a sun rising, the other icons not shown on the
display (100) may either be hidden from or visible to the user. In case the other
icons are hidden from the user, an opaque cover 160 may be provided. In case the other
icons are not hidden from the user, a cover (160) is not necessary, or if provided,
it may be transparent.
[0109] Figure 50 and the enlarged portion of Figure 50 shown in
Figure 51 show a "second level" system where also minutes and seconds are shown in one of the
displays, for example a digital display such as display (101) of Figure 51. The other
display (102) shows an icon (103) thematically associated with the time shown in the
display (101).
[0110] Figure 52 and the enlarged portion of Figure 52 shown in
Figure 53 show a "third level" system where one of the displays shows the time, for example
in an analog manner as indicated by display (104) and the other display (105) shows
an area for different modes that may include information thematically related with
the time shown in display (104) and variable according to the skill of the user. The
enlarged portions of the system of Figure 52, shown in Figure 53, are examples of
multiple modes of the area shown in display (105) aiding a child in the learning and
incorporating of time into the child's day.
[0111] For example, the enlargement (106) shows the area of the display (105) in an animation
mode; the enlargement (107) shows the area of display (105) in an activity mode where
the watch counts down a major event in a child's day, for example lunch time; in the
enlargement (108), the area of display (105) is in a time quiz game mode; in the enlargement
(109) the area of display (105) shows, in a digital format, a time relating to the
time shown in display (104) in an analog format; and in the enlargement (110) the
area of display (105) is in an alarm mode.
[0112] Additionally, sounds and animation may also be displayed in all of the embodiments
of the system.
[0113] The system may be assembled to other items, and in particular to any watch band known
in the art, possibly including the snap mechanism according to the present disclosure.
The assembly may be made using a technology known in the art and identifiable by the
person skilled in the art or by realizing a hinging assembly in accordance with the
teachings of the present disclosure.
[0114] The relative size of the first and second display can vary. The first display can
have a size which is greater than, less than or equal to the size of the second display.
[0115] In summary, a magnet assembly connectable to a metal assembly in an engaging fashion,
a metal assembly connectable with the magnet assembly in an engaging fashion and a
snapping mechanism comprising the magnet assembly and the metal assembly are disclosed,
to be used with a strap and a watch case. A leaf spring element and a base element
to be used with a watch case are also disclosed, together with manufacturing processes
and a system and method to teach the concept of time.
[0116] The present disclosure has been explained with reference to specific embodiments.
Other embodiments will be apparent to those of ordinary skill in the art in view of
the foregoing description. The scope of protection of the present disclosure is defined
by the appended claims.
