Device whereby a wristwatch in particular is rendered reversible
and interchangeable relative to a holder
Abstract
The aim of the present invention is to provide a device whereby
various wristwatch movements can be fitted to a single strap,
meaning that the watch can be replaced or reversed quickly without
opening the strap or case. This aim is achieved by means of a
device whereby an object such as a watch case is rendered
reversible and interchangeable in a supporting element that is open
on one side so that the reversible and interchangeable object can
be inserted or withdrawn through said side opening, characterised
in that said side opening is sealed by a portion of the reversible
and interchangeable object that fits snugly onto the open side of
the supporting element, thereby locking same. The device comprises
retaining means for retaining the reversible and interchangeable
object within the supporting element. It should be noted that in
one embodiment of the device, there is no strap (100) and a clip
(300) is inserted into portions (202, 203) of the supporting
element (200) so that the assembly can be used as an adornment.

Description
[0001] The present invention relates to the field of jewelry and
watch-/clock-making, more particularly to devices allowing the
reversal and interchanging of an object, particularly a watch,
relative to a holder.
[0002] With the market for modulable watches experiencing active
growth, more and more watch manufacturers are proposing goods based
on the use of modules.
[0003] The functional modules that make up a modulable watch are,
in particular, a strap, a watch case, and a supporting element.
These functional modules are obviously supplemented by all the
components that make up the range of decorative elements that can
be placed, in particular, on said functional modules. Watch users
seeking modulable devices are thus able to convert their watches in
accordance with their wishes at any time.
[0004] A watch strap is an adornment that generally surrounds the
wrist and is fitted to the watch case by means of fastening
elements such as small bars or small screws that are fixed in studs
of said case, the latter having a case band in which the movement
is placed.
[0005] In order to insert and to fasten a watch case on its holder,
it is known to use a device such as that illustrated in publication
JP 2001091672, in which the watch case is inserted laterally into a
case support forming a holder closed by a lever. Once the latter
has been immobilized, the watch case is completely surrounded by
the holder and thus fastened.
[0006] Such a device is fragile around the pivot point of the lever
and difficult to produce. Indeed, rotation of the closure lever
around a small-diameter rod may give rise to the unexpected exit of
said rod or, in the worst case, breakage of the rod, thus leading
to the opening of the lever and consequently the unexpected exit of
the watch case.
[0007] The major drawback of this device lies in the fragility of
the components that require a high level of precision and
consequently are expensive to manufacture.
[0008] An object of the present invention is to propose a device
that is easy to handle, reliable, robust and that allows the
insertion and sideways removal, particularly of a watch case
carrying a watch movement relative to a holder.
[0009] This object is achieved by means of a device allowing the
reversal and interchanging of an object such as a watch case in a
supporting element open on a lateral side allowing the insertion
and the removal of the reversible and interchangeable object via
said lateral opening, characterized in that this lateral opening is
closed by a portion of the reversible and interchangeable object
that fits snugly on the open lateral side of the supporting
element, thus fulfilling the function of a lock for the supporting
element, the device including closure means for retaining the
reversible and interchangeable object in the supporting
element.
[0010] A device according to the invention allowing the reversal
and interchanging, in particular of a watch case relative to an
open supporting element is advantageously composed of a strap, a
supporting element--for example an open case band--a watch case and
at least one closure pusher.
[0011] The watch case is inserted sideways into its holder and
secured to the latter by at least one closure pusher that
immobilizes the entire device when the case reaches the end of
travel in its housing. The case band is fitted to the strap, for
example, conventionally by means, in particular, of screws that
fasten said strap to the supporting element.
[0012] It should be noted that in one specific case, the user may
have a clip-style watch or a bedside watch instead of a
wristwatch.
[0013] Furthermore, the device that is the subject of the invention
includes a watch case or an assembly of two cases that can be
reversed and interchanged.
[0014] The invention will be better understood by virtue of the
following description, given by way of example, referring to the
appended drawings, in which:

[0025] FIG. 11 shows a perspective view of a clip-style watch, as a
variant embodiment of the invention.
[0026] A device allowing the reversal and interchanging, in
particular, of a watch relative to a support, is composed of a
watch case (400--FIG. 1), a holder (200--FIG. 1) in the form of a
"U" into which the case (400) is inserted sideways, at least one
closure pusher (500--FIG. 1) in order to immobilize the device, and
a strap (100--FIG. 2).
[0027] FIG. 2 illustrates an assembly of the elements that make up
the device allowing the reversal and interchanging, in particular
of a watch relative to a holder, into which a watch movement (404)
is inserted, this being in the case of a wristwatch.
[0028] The supporting element (200), illustrated in detail in FIGS.
3, 4, and 5, includes two rectilinear portions (202, 203) connected
together by a curved portion (204), thus giving a "U" or "C" shape
to said holder (200). The rectilinear portions (202, 203) include
grooves (210) over their entire outer length, allowing the
insertion of the ends (111--FIG. 10) of the strap (100), and
cavities (201) on the upper face where the pushers (500) are
accommodated.
[0029] The inside of the supporting element (200) includes a
semicircular milling (208)--called a "rail"--in which cavities
(812) are machined perpendicularly to the cavities (201) so as to
allow the insertion of guide plates (820) that will be fastened to
the pushers (500) by means of screws (830) after said pushers (500)
have been inserted into the cavities (201), compressing springs
(840).
[0030] One side (1000--FIG. 5) of the holder (200) remains open in
order to allow the insertion of the watch case (400).
[0031] The watch case (400), illustrated in FIG. 7, includes two
rectilinear sides (410, 420) connected together by means of two
curved sides (401, 430). A semicircular boss (402), designed to be
inserted in the rail (208) in order to guide the watch case (400),
is milled on the sides (410, 420, 430).
[0032] On its sides (410, 420) the boss (402) bears perpendicular
millings (403) that allow the insertion of the guide plates (820),
which has the purpose of immobilizing the watch case (400) in the
supporting element (200).
[0033] It should be noted that the side (401) does not bear a boss
(402) and fits snugly on the open side (1000) of the supporting
element (200).
[0034] FIG. 8 illustrates a guide plate (820) that includes a rear
face (950) with a particularly rectangular surface from which
projects a guide stud (903) designed to be inserted in the closure
pusher (500), two lateral faces (960, 970) and a front face
(950).
[0035] It should be noted that a central orifice (902) designed to
receive the fastening screw (830) passes right through the guide
plate (820).
[0036] The front face (950) of the guide plate (820) is machined
such that the lateral face (960) includes a rectilinear portion
(900) that is shorter than a rectilinear portion (911) of the
lateral face (970) located opposite the latter. This machining is
obtained by increasing the radius of curvature (904) of the lateral
face (960) progressively up to the radius of curvature (912) of the
lateral face (970). The result of this machining is the production
of a ridge (907) that is asymmetric relative to an upper face (908)
of the guide plate (820), said ridge (907) serving to guide the
boss (402) of the watch case (400) via its lateral face (970) and
to immobilize the watch case (400) via its lateral face (960) when
the guide plate (820) is inserted in the groove (403) of said boss
(402).
[0037] The closure pushers (500), as illustrated in FIG. 9, have an
upper face (505) on which a user has to press in order to release
the device, a lower face (506) in which the springs (840) that hold
the pushers (500) in the position of immobilizing the device are
accommodated, a front face (503) that has a milling (507) in which
the guide plate (820) is accommodated, a rear face (504) that has a
recess (520) in which an end-of-travel screw (860--FIG. 6) is
accommodated, and two lateral faces (501, 502) joining the rear and
front faces of the pushers (500).
[0038] It should be pointed out that the milling (507) includes, at
its center, a bore (521) designed to receive the stud (903) of the
guide plate (820), said bore (521) having a central orifice (508)
in which the end of the fastening screw (830) is accommodated.
[0039] The strap (100) is, in particular, a conventional strap. Its
ends (111) are inserted in the rectilinear portions (202, 203) of
the supporting element (200) and are held, in particular, by the
screws (205) and fastening plates (110) as illustrated in FIG.
10.
[0040] The compression springs (840) are inserted in extensions
(890--FIG. 6) of the cavities (201) located on the rectilinear
portions (202, 203) of the supporting element (200) and provided
for this purpose.
[0041] The closure pushers (500) are arranged on the springs (840),
the latter being inserted in said pushers (500) via the lower faces
(506) of the latter.
[0042] By pressing on the upper faces (505) of the pushers (500)
the springs (840) are compressed until the cavities (880--FIG. 6)
located in the recesses (520) of the pushers (500) are positioned
opposite the end-of-travel screws (860), which makes it possible,
by inserting the screws (860) in said cavities (880), to prevent
the pushers (500) exiting the cavities (201), to keep the springs
(840) compressed, and to limit the travel of the pushers (500) from
one wall to the other of the cavity (880). The upper wall of the
cavity (880) abuts against the screw (860) when the pusher (500) is
pushed into its inner, working position, whereas the lower wall of
the cavity (880) abuts against the screw (860) when the pusher
(500) is released into its outer, rest position.
[0043] When the pusher (500) is in its rest position, the recess
(507) of said pusher (500) is positioned over the cavity (812) of
the rectilinear portions (202, 203) of the supporting element
(200), thus allowing the insertion of the guide plate (820)
positioned by the stud (903) of the plate (820) inserted in the
cavity (521) of the pusher (500). The assembly is then secured by
the screws (830).
[0044] It should be noted that the faces (970) of the plates (820)
are positioned on the side (1000) of the supporting element (200)
so that the radius (912) of the plates (820) corresponds to the
radius of the guide (208).
[0045] The watch case (400) is inserted via the open side (1000) of
the supporting element (200) by placing the rectilinear flanks of
the guide (402) in the rail (208). The latter thus controls the
insertion of the case (400) with the aid of said guide (402).
[0046] The flanks of the guide (402) are inserted in the guide
plates (820) and bear, moving in the rail (208), on the ridges
(907) of said plates (820), which has the result of bringing the
pushers (500) into their inner, working position, compressing the
springs (840).
[0047] When the plates (820) and the grooves (403) are in line, the
springs (840) push the pushers (500) into their rest position,
which has the result of opposing the faces (860) of the plates
(820) vis-a-vis the inner edges of the groove (403), thus
immobilizing the watch case (400) in the supporting element
(200).
[0048] In the locked position of the watch case (400), the portion
(401), which does not have a guide and is not machined, fits snugly
on the open side (1000) of the supporting element (200), thus
acting as a lock for the holder (200).
[0049] In order to release the device, the pushers (500) are
pressed simultaneously in order to allow the guides (402) to be
inserted into the rounded portions (904) of the guide plates (820).
The guide (402) is thus able to guide the case (400) in the
direction of removal.
[0050] In one embodiment, the device allowing the reversal and
interchanging of an object such as a watch case in a supporting
element includes two watch cases (400) secured together back to
back.
[0051] It should be noted that the device allowing the reversal and
interchanging in particular of a watch relative to a holder
includes, in the case illustrated, by FIG. 11, a clip (300) that
replaces the strap (100) so that the watch can be worn as an
adornment or be used as a bedside clock. The clip (300) is, for
example, fastened to one of the rectilinear portions (202, 203) of
the supporting element (200) and extends toward the opposite
portion, bearing toward the rear face of the case (400) when the
latter is inserted into the supporting element (200). In order to
use it as a bedside clock, it is possible to make provision for the
supporting element (200) to have other forms.
