Abstract

The buckle for a belt or a strap comprises an ardillion (800) mounted on a movable lever (801) for being placed in at least two positions, a upper one where the ardillion is not engaged in a hole of said belt or strap, and a lower one where the ardillon is engaged in a hole (7) of said belt or strap. Said lever is mounted in an adjustment lever (90) of the buckle that allows the belt to take at least a loose position and a tight position.

Description

LOCKING BUCKLE FOR A BELT OR A STRAP SUCH AS A WATCH STRAP
REFERENCE TO EARLIER APPLICATION The present application claims priority to earlier Swiss application N°01259/14 filed on August 22, 2014 in the name of ROLAND ITEN MECHANICAL LUXURY S.A., the content of this earlier application being incorporated by reference in its entirety in the present application. TECHNICAL FIELD
The present invention concerns the field of buckles for belts or straps, such as watch straps and other similar products. More specifically, the present invention concerns a buckle that makes it easy to adjust the length of the belt or strap and also to open or close the buckle.
BACKGROUND ART Belt buckles are well known in the art and have been made for ages. Some are very simple and only allows definite size of the belt. Other a little more complicated allow a continuous adjustment of the size of the belt.
A belt or watch strap generally comprises two parts: a buckle and a leather belt/strap. The belt itself may also be made out of materials other than leather. In the case of a watch strap, this comprises a leather strap rather than the leather belt, whereby this may also be made out of materials other than leather.
Some luxury products are made of complicated mechanisms that can be fabricated out of precious metals for example. Examples of known buckles and straps are disclosed in publications WO 2012/1 17326A, CH 703 808 B1 , CH 702 774 B1 , CH 706 438 A2, WO 2007/1 13638 the contents of which are incorporated by reference in the present application in their entirety.
SUMMARY OF THE INVENTION
An aim of the present invention is to improve the buckles known from the prior art when used with a belt or a watch strap or other similar products. In particular, an aim of the present invention is to provide a buckle that is simple and convenient to use and that allow a safe mounting on the belt/strap.
Embodiments of the invention are defined in the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS
Figures 1 A to 1 F illustrate a first embodiment of the invention;
Figures 2A to 2D illustrate the functioning of a part of the present invention;
Figures 3A to 3D illustrate the functioning of another part of the present invention.
DETAILED DESCRIPTION
The invention will be explained now by reference to the figures. In the following, the same elements will be referenced with the same or corresponding references. Also, the notion of belt or strap will be used indifferently, it being clear that they are equivalent and the use of the present invention is not limited to a belt or to a watch strap but also to other similar systems. An embodiment of the invention is illustrated in Figure 1 A (front view) and it shows a belt strap 6 with at least one hole 7. The buckle comprises an adjustment lever 90 carrying a frame 9 which holds a lever 801 supporting an ardillion 800 (see figure 1 B) for example via a screw.
The lever 801 is described in more detail in figure 1 B (top, side views and detail on the right).
The lever 801 is articulated on frame 9 via axis 810 and may take the positions illustrated in figures 1 D to 1 F, said positions being about 90° apart.
The lever 801 carries the ardillion 800 with is to be inserted in a hole 7 of the belt 6 as seen in figures 1 D and 1 E. Therefore, the ardillion 800 preferably has the shape illustrated to facilitate its insertion.
The lever 801 also carries a pin 802 for unlocking the lever 801 . The locking mechanism is illustrated in detail in figure 1 C and comprises a cage 803 with a ball which are attached to the frame 9 and the pin 802 on the lever 801 . When the lever 801 is essentially aligned with the frame 9, the ball penetrates in one side of a hole of the lever 801 thus locking the relative position of the lever 801 with respect to the frame 9. To unlock the mechanism and allow the lever 801 to rotate on its axis 810, the user pushes the pin 802 in the hole towards the ball and this movement disengages the ball from the hole and allows a relative movement (for example rotation) of the lever 801 with respect to the frame 9. The curved shape of the lever helps the user reach the pin 802 with one finger. Of course, other equivalent means may be envisaged.
The movement of the pin 802 (and to ensure it remains attached to the lever 801 ) is ensured for example via a screw (see figure 1 B, right side detail). Of course the parts forming the locking mechanism could be inverted and the pin placed on the frame 9 and the ball/cage 803 on the lever 801 . Other equivalent constructions are possible as well. Reference 91 identifies a frame axis which allows a relative rotation of frame 9 relatively to adjustment lever 90 and reference 93 an adjustment lever axis allowing a rotation of the lever 90 (see figures 3A-3D described hereunder) on a platform 92 of the buckle. The introduction of the ardillion 800 in the desired hole 7 of the belt 6 is illustrated in figures 1 D to 1 F. In figure 1 D, the lever 801 is in an open position allowing the adjustment of the buckle on the belt 6. Once a proper size has be reached, the lever 801 is rotated downward of about 90° relatively to frame 9 such that the ardillion 800 penetrates in the chose hole 7 (figure 1 E). This rotation bring the lever 801 in a locked position (figure 1 F) using the locking mechanism discussed above.
Figure 2A illustrates a top view of the buckle with a raised lever 801 (i.e. unlocked) as in figure 1 D.
Figure 2B shows a side view in partial cut of the situation of figure 1 D in the buckle.
Figure 2C illustrate a top view of the buckle with a lever 801 as in figures 1 E/1 F in locked position, essentially aligned with frame 9, the ardillion 800 being inserted in the chose hole 7 (see Figure 2D which shows a side view in partial cut of the situation of figures 1 E/1 F in the buckle).
Figures 3A to 3D illustrate the adjustment mechanism of the buckle that allows an adjusted belt to easily be put in a loose position or tight position, the loose position being when the overall size of the belt is greater than the size in the tight position. This aim is achieved by the movement of the adjustment lever 90 of about 180°. Figure 3A illustrate the loose position and corresponds to the buckle as shown in figures 1A, 2A and 2C discussed above.
The lever 90 may be rotated to the right of an angle of about 180°, see figures 3B and 3C, to reach another position as illustrated in figure 3D. This position is a tight position where the overall size of the belt (or strap) is smaller than in the loose position.
Such two different positions are interesting for taking account of the position of the wearer of a belt with this buckle and its comfort, for example sitting or standing or during a meal. For example when sitting (and maybe eating) the loose position will be preferred whereas when standing the tight position will be chosen
If the belt/strap is a watch strap, these two positions may be useful when the wearer wishes to carry the watch underneath his clothes (the tight position will be preferred) or over his clothes (then the loose position may be better). This is particularly useful when the clothes are thick, for example a diving suit in which activity the diver's watch must be attached over the suit.
The examples given in the present specification are only for illustrative purposes and should not be construed in a limiting manner. Other constructions are possible using equivalent means and within the spirit and scope of the present invention. The embodiments described herein may also be combined as desired.
As mentioned, the buckle of the present invention may be used for a belt or for a strap such as a watch strap. Other uses are of course possible for other devices and in other contexts. The parts of the present invention may be made in any suitable materials: metals, alloys, precious metals or alloys, synthetic or plastic materials and any combination thereof etc.
