Abstract
A buckle for a watchband comprising a first arm having a first end and a second end, wherein the first end of the first arm is hingedly coupleable to first watchband portion; and a latch, the latch extending from a surface of the first arm; a second arm having a first end and a second end, wherein the first end of the second arm is hingedly coupled to the second end of the first arm, the second arm further having an aperture sized to permit the latch to pass therethrough when the first arm is rotated into a “surface to surface” alignment with the second arm; a shell, the shell being hingedly coupled to the second end of the second arm and hingedly coupleable to a second watchband portion; and a latching mechanism, coupled to the shell, wherein the latching mechanism comprises a backing plate having an aperture sized to permit the latch to pass therethrough; a locking plate, coupled to the backing plate and biased relative thereto, for engaging and latching the latch when the latch is passed through the aperture in the backing plate; wherein the locking plate is moveable in a engaging direction to engage and latch the latch within the latching mechanism and further, wherein the locking plate is moveable in a direction opposite the engaging direction to permit the latch to be delatched from the latching mechanism. In this way, the delatching of the latch from the latching mechanism permits at least the first end of the first arm to be moved in a direction away from the shell.
Description
BACKGROUND OF THE INVENTION
The present invention relates generally to wristwatches and in particular, to an improved construction of a wristwatch buckle that more reliably secures a wristwatch to a wrist.
Wristwatch foldover buckles are well known in the art. Most typically, such foldover buckles are used in connection with wristwatches that utilize a metal wriststrap. A metal foldover buckle most cosmetically and aesthetically integrates with such a particular style of wristwatch strap. However of course, as with the present invention, using a metal wriststrap is by way of example and not limitation.
FIG. 1
illustrates a conventional foldover buckle, generally indicated at
1
. Details of such a buckle will be omitted herein for brevity, as the function, construction and design thereof should be well known to someone skilled in the art. However, for purposes of identifying at least one significant distinction between the state of the art foldover metal buckles and the present invention, the following is set forth. Namely, foldover buckle
1
utilizes a “C-shaped” catch
2
. When arms
3
and
4
of buckle i are folded over for closure within shell
5
(see discussion below for detailed understanding of how a foldover buckle can be closed), “C-shaped” catch
2
will engage and “snap” onto the end of arm
4
which itself is hingedly coupled to shell
5
about a spring bar
6
which itself is the pivot point about which arm
4
rotates relative to shell
5
.
Undesirably, there are times when a banging or simple shaking of buckle
1
, when incorporated into a wristwatch, can cause catch
2
to unhook from the end of arm
4
. In this situation, buckle
1
will move towards the open position illustrated in FIG.
1
. The undesirable result is that the wristwatch may drop off the wrist or merely, but still inconveniently, catch
2
may need to be “reshaped” onto the end of arm
4
. That is, if catch
2
becomes disengaged with the end of arm
4
at the inopportune moment, there is the possibility that the wristwatch my slide or otherwise fall off the person's wrist thereby becoming broken or lost.
Accordingly, an improved foldover buckle construction for more reliably securing a wristwatch to a wrist is desired. The present invention overcomes the aforementioned deficiencies and provides the objectives and advantages set forth below.
OBJECTS AND SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide an improved foldover buckle for a wristwatch.
It is another object of the present invention to provide an improved foldover buckle that can be more reliably secured so as to more reliably secure a wristwatch to a user's wrist.
Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.
The invention accordingly comprises the features of construction, combination of elements and arrangement of parts that will be exemplified in the disclosure hereinafter set forth, and the scope of the invention will be indicated in the claims.
Generally speaking, the present invention is directed to an improved buckle for a watchband. In a preferred embodiment, the buckle comprises a first arm having a first end and a second end, wherein the first end of the first arm is hingedly coupleable to first watchband portion; and a latch, the latch extending from a surface of the first arm; a second arm having a first end and a second end, wherein the first end of the second arm is hingedly coupled to the second end of the first arm, the second arm further having an aperture sized to permit the latch to pass therethrough when the first arm is rotated into a “surface to surface” alignment with the second arm; a shell, the shell being hingedly coupled to the second end of the second arm and hingedly coupleable to a second watchband portion; and a latching mechanism, coupled to the shell, in which the latching mechanism preferably comprises a backing plate having an aperture sized to permit the latch to pass therethrough; a locking plate, coupled to the backing plate and biased relative thereto, for engaging and latching the latch when the latch is passed through the aperture in the backing plate. Constructed in this manner, the locking plate is moveable in a engaging direction to engage and latch the latch within the latching mechanism and is moveable in a direction opposite the engaging direction to permit the latch to be delatched from the latching mechanism, whereby the delatching of the latch from the latching mechanism permits at least the first end of the first arm to be moved in a direction away from the shell.
In a particular embodiment, the latch comprises a shaft and a head, and the locking plate includes an aperture sized to permit the head of the latch to pass therethrough, the locking plate further comprising a finger for engaging the head of the latch when the head of the latch is passed through the aperture in the locking plate. In a preferred construction, the locking plate is rotatably mounted to the backing plate. A spring preferably biases the locking plate relative to the backing plate and exerts a spring force upon the locking plate so as to bias the locking plate in the engaging direction.
A wristwatch comprising the aforementioned buckle is also provided herein.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made to the figures wherein a foldover buckle including a latching mechanism, and a wristwatch incorporating at least the foregoing, all as constructed in accordance with the present invention, is disclosed. Reference to the particular figures where appropriate will be set forth.
In accordance therewith and generally speaking, reference is first made to
FIGS. 2 and 3
wherein a foldover buckle, generally indicated at
8
, constructed in accordance with the present invention, is disclosed. In particular, illustrated in
FIGS. 2 and 3
is a first arm
10
, a second arm
12
and a shell
14
. First arm
10
has a first end
11
and a second end
13
, wherein first end
11
of first arm
10
is hingedly coupleable to first watchband portion (an exemplary link “L” which would be understood to be preferably linked to a plurality of similar links (see FIG.
11
)). A latch, generally indicated at
22
, the function of which will be explained below, can be seen to extend from a surface of first arm
10
. In a preferred embodiment, latch
22
can be riveted, welded, soldered or attached to first arm
10
in any number of ways, all within the purview of one skilled in the art.
A second arm
12
, itself having a first end
15
and a second end
17
, is hingedly coupled to first arm
10
by the coupling of first end
15
of second arm
12
to second end
13
of first arm
10
. The hinge therebetween most preferably includes a pin
18
. For reasons that will become clear below, second arm
12
includes an aperture
19
sized to permit latch
22
to pass therethrough when first arm
10
is rotated into a “surface to surface” alignment with second arm
12
. A shell
14
is hingedly coupled to second end
17
of second arm
12
. When fully constructed as part of a wristwatch, shell
14
will also be hingedly coupled to a second watchband portion (FIG.
11
). Aperture
14
c
, with a similar aperture also being on the nonviewable side of shell
14
in
FIG. 2
, is sized for the springbar of such a second watchband portion.
For purposes of better appreciating the construction and function of the latching mechanism described in greater detail below, an understanding of the relative movement of arms
10
and
12
will first be explained. Specifically, as with conventional foldover buckles, first arm
10
is arcuate so as to define an inner surface
10
i
and an outer surface
10
o
. As is clear, latch
22
extends outwardly from outer surface
10
o
. Similarly, second arm
12
is arcuate so as to define an inner surface
12
i
and an outer surface
12
o
. In the preferred embodiment, second arm
12
is hingedly coupled proximate an end of shell
14
. As can be seen in the side surfaces of shell
14
, apertures appear as in conventional shells of foldover buckles. These apertures receive springbars or pins, similar to pin
20
, therethrough. In this way, along with removing links such as one or more links “L”, the watchband can be shortened or lengthened. This should be clear to one skilled in the art. In order for arms
10
and
12
to be in what has been coined herein as “surface to surface” alignment, the following occurs when the buckle
8
moves towards its locked position (
FIG. 2
illustrates the opened position).
Namely, first end
15
of second arm
12
is rotated in the direction indicated by arrow “x” in
FIG. 2
relative to second end
17
of second arm
12
which remains hinged to shell
14
, while first end
11
of first arm
10
is rotated in the direction indicated by arrow “y” (
FIG. 1
) relative to first end
15
of second arm
12
which remains hinged to second end
13
of first arm
10
. This results in the outer surface
12
o
of second arm
12
to rotate in direction “x” towards shell
14
(see FIG.
7
), the outer surface
10
o
of first arm
10
to move in the direction “y” towards and align with inner surface
12
i
of second arm
12
, and latch
22
to move towards and pass through aperture
19
in second arm
12
as latch
19
moves towards shell
14
. In this way, arms
10
and
12
are in “surface to surface” alignment (see FIG.
7
). A raised channel
28
and a corresponding recessed channel
30
may be provided in arms
10
and
12
(or visa versa), respectively, to assist in maintaining a secured “surface to surface” alignment. These channels are known the art and immaterial to the present invention.
Reference is now made to
FIGS. 4-10
in connection with the following for an understanding of the latching mechanism, generally indicated at
45
, constructed in accordance with the present invention. In particular, the three element construction of latching mechanism
45
comprises a backing plate, generally indicated at
50
; a locking plate, generally indicated at
60
, and a biasing member
70
, in the preferred embodiment biasing member being a spring. It is only a matter of convenience that latch
22
is not disclosed in connection with latching mechanism
45
, as latch
22
may of course be considered part of latching mechanism
45
.
Backing plate
50
includes an aperture
51
sized to permit latch
22
to pass therethrough. Backing plate
50
includes folded over grasping members for rotatably holding springbars
46
and
47
. The proper bending of backing plate
50
can form the properly dimensioned grasping members. Backing plate
50
is coupled to shell
14
by the insertion of springbars
46
and
47
in respective apertures
14
a
and
14
c
(FIG.
2
). Locking plate
60
is coupled to the backing plate via a center tab
52
on backing plate
50
. Locking plate
60
engages and latches latch
22
when latch
22
is passed through aperture
51
in backing plate
50
. Locking plate
60
is biased relative to backing plate
50
by use of biasing member
70
. As will be explained below, locking plate
60
is moveable in a engaging direction (see arrow “ccw” in
FIG. 4
) to engage and latch
22
within latching mechanism
45
and further is moveable in a direction opposite the engaging direction (see arrow “cw” in
FIG. 4
) to permit latch
22
to be delatched from latching mechanism
45
. As will be shortly understood, the delatching of latch
22
from latching mechanism
45
permits at least first end
11
of first arm
10
to be moved in a direction away from shell
14
towards an open position (FIG.
2
).
Latch
22
comprises a shaft
26
and a head
24
such that head
24
preferably has a greater width than shaft
26
. Of course a notch in latch
22
will provide the operable function and will delineate a head and shaft as disclosed herein.
Locking plate
60
also includes an aperture
61
sized to permit at least head
24
of latch
22
to pass therethrough. Locking plate
60
further comprising a finger
62
that may extend slightly into aperture
61
for engaging head
24
of latch
22
when head
24
of latch
22
is passed through aperture
61
in the locking plate. Finger
62
may also be bent slightly in a direction out of the paper as viewed in FIG.
8
.
As can be seen, locking plate
60
is preferably rotatably mounted to backing plate
50
(as it is mounted on tab
52
of backing plate
50
). In this way, when locking plate
60
rotates in the direction opposite the engaging direction (i.e. when it rotates in direction “cw”), head
24
of latch
22
is passable by finger
62
of locking plate
60
, and when locking plate
60
rotates back in the engaging direction (i.e. in direction “ccw”), finger
62
engages head
24
of latch
22
thereby latching latch
22
in latching mechanism
45
.
It should be pointed out that other constructions are contemplated herein, and the claims are intended to cover such alternatives. As one example, it should now be understood that locking plate
60
may be a “push plate” relative to locking plate
50
. That is, locking plate
60
need not be rotatably mounted on backing plate
50
but rather only spring mounted on so that a pushing action latches and delatches latch
22
from an equivalent locking plate. The push plate would be spring biased relative to the equivalent backing plate.
In the preferred embodiment, backing plate
50
comprises a stopper
53
that will extend through aperture
61
in locking plate
60
(i.e. out of the paper as viewed in
FIG. 6
) when locking plate
60
is mounted on backing plate
50
. Stopper
53
hits an edge “e” of aperture
61
and prevents the unnecessary overrotation of locking plate
60
in the direction opposite the engaging direction (i.e. in the “cw” direction) and prevents an overbiasing of locking plate
60
relative to backing plate
50
. That is, spring
70
should not get overly compressed.
That is, latching mechanism
45
comprises spring
70
to bias locking plate
60
relative to backing plate
50
. The spring force upon locking plate
60
biases locking plate
60
in the engaging direction (“ccw” direction). To this end, locking plate
60
preferably comprises a second aperture
63
therethrough and a tab
64
proximate an edge of aperture
63
while backing plate
50
comprises a tab
54
extending through aperture
63
, again, when plate
60
is mounted on backing plate
50
. In this way, spring
70
is disposed intermediate tab
54
of backing plate
50
and tab
64
of locking plate
60
so as to bias locking plate
60
in the (“ccw”) engaging direction. Tab
54
may be formed by bending back a cut-out section in backing plate
50
(note aperture
55
formed thereby in
FIGS. 6
,
10
). It should be understood that tabs
54
and
64
should be seen to be coming out of the page in FIG.
5
. Also, it should be understood that a channel
65
is formed in locking plate
60
(note consistency between
FIGS. 4
,
7
,
8
).
As illustrated in
FIG. 7
, among others, locking plate
60
is intermediate backing plate
50
and the internal cavity of shell
14
.
To facilitate the rotation of locking, plate
60
, integrally formed wings
67
,
68
extending outwardly therefrom are provided. Wings
67
,
68
preferably include knurled outer surfaces and extend sufficiently outwardly from the sides of backing plate
50
sufficient for engagement by a user's fingers. In this way, when head
24
of latch
22
is engaged by finger
62
of locking plate
60
, the rotation of locking plate
60
by the wings
67
,
68
thereof in a (“cw”) direction opposite the (“ccw”) engaging direction causes locking plate
60
to rotate causing finger
62
to disengage from latch
22
. Latch
22
may then be removed from latching mechanism
45
. Backing plate
50
may comprise integrally formed sides
56
,
57
that extend outwardly therefrom almost as far outwardly as wings
67
,
68
. This will provide added stability to locking plate
60
.
As set forth above, backing plate
50
comprises a first end for retaining spring bar
46
and a second end for retaining a second spring bar
47
. Backing plate
50
is coupled to shell
14
by the securing of first and second spring bars
46
and
47
in apertures
14
a
and
14
c
, respectively, and their respective counterpart apertures (not shown) on the other side of shell
14
.
Reference is once again made to
FIG. 10
so as to ensure a complete understanding of the construction of the present invention. In particular, shell
14
with latching mechanism (not shown since it is on the underside of shell
14
) is shown. Also shown are two separate watchstrap portions
74
and
76
comprising a plurality of links “L.” It should be understood that there will be more links “L” in each portion
74
and
76
so as to fit around a user's wrist. Also a watchhead
78
completes a wristwatch
80
constructed in accordance with the present invention. An exemplary watchhead comprising timekeeping functionality and a first end and a second end for respectively being coupled to the ends of the watchstrap portions
74
and
76
, is illustrated in U.S. Pat. No. 5,305,291, the disclosure of which is incorporated by reference as if fully set forth herein. In this manner, it should be clear that an entire wristwatch is fully disclosed.
In operation, wristwatch
80
is slipped onto a wrist. Buckle
8
will be in the open position as illustrated in
FIG. 2
so as. to get wristwatch
80
around one's wrist. Next, arms
10
,
12
are moved into “surface to surface” alignment as disclosed above, causing latch
22
to pass through the aperture in arm
12
. As latch
22
passes aperture
51
in backing plate
50
, it will contact finger
62
on locking plate
60
. A user can, if desired, rotate locking plate in the “cw” direction so as to move finger
62
out of the way to allow head
24
of latch
22
to pass thereby. Alternatively, and more preferably, a user will just put pressure on arm
10
relative to shell
14
so as to forceably cause finger
62
to move out of the way of latch
22
by the force of head
24
against finger
62
as head
24
is sliding by finger
62
. In this way, finger
62
is, rotatably moved out of latching engagement with latch
22
. Once head
24
passes finger
62
, locking plate
60
will “snap” back into latching engagement with latch
22
by way of the biasing of locking plate
60
relative to backing plate
50
. A head as shown on latch
22
of
FIG. 2
works well for this purpose.
Latch
22
is now releasably locked (or latched) in latching mechanism
45
.
To detach latch
22
from latching mechanism
45
, a user causes the rotation of locking plate
60
in the “cw” direction by the grabbing and rotation of wings
67
,
68
. In this way, finger
62
disengages from latch
22
. At this time, arm
10
may be pulled away from shell
14
so as to allow buckle
8
to open (FIG.
2
). Wristwatch
80
may thereafter be slipped off a user's wrist.
It will thus be seen that the objects set forth above, among those made apparent from. the preceding description, are efficiently attained and, since certain changes may be made in the above constructions without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. For example, buckle
8
is preferably made of metal. Watchstrap portions
74
and
76
are also preferably made of metal although other material, such as leather, if desired, may be used.
While the invention has been particularly shown and described with respect to preferred embodiments thereof, it will be understood by those skilled in the art that changes in form and details may be made therein without departing from the scope and spirit of the invention.
