Description

FIELD OF THE DISCLOSURE

This invention relates to watches.

BACKGROUND OF THE DISCLOSURE

Nowadays, watch owners, especially owners of expensive mechanical or quartz watches, face the risk of theft for subsequent use or resale, as well as risk of loss.

None of the currently existing mechanical or quartz watches are equipped with mechanical aids to prevent their unauthorized use.

SUMMARY OF THE DISCLOSURE

Thus, the object of the present invention is to create a watch containing a means of preventing its unauthorized use.

In particular, according to the invention, the created watch contains a case with a removable cover and a clock mechanism installed in the case including a setting/winding mechanism, characterized by a combination lock used to block the setting/winding mechanism and block removing the cover from the case to prevent unauthorized use of the watch.

The technical result of the invention consists in reducing the likelihood of the watch theft owing to impossibility of its subsequent use thanks to the installed combination lock blocking the setting/winding mechanism and removal of the cover from the case to prevent unauthorized use of the watch.

Indeed, the combination lock which blocks the setting/winding mechanism and prevents the case cover removal, makes stealing of the watch, as well as its subsequent resale, almost senseless, since it will take the thief a huge amount of time to figure out the code to unblock this combination lock, and remove the watch cover to unlock the setting/winding mechanism. Any attempt to break or open the lock without entering the correct code will damage the watch and lead to the loss of its value.

In addition, the design of the combination lock is quite simple and compact, allowing its easy integration both into already existing watches and watches being prepared for release.

The clock mechanism preferably comprises mechanical or quartz mechanism.

The setting/winding mechanism preferably comprises a spindle with a clock winder (crown).

The combination lock is preferably a dial (twist) lock that provides adequate protection for the watch due to the numerous combinations for unlocking it.

The dial lock is preferably arranged on a separate spindle associated with the setting/winding mechanism.

The cover is preferably connected to the case by means of a threaded connection, and the lock bolt of the dial lock has a locking element to block the cover in the closed position of the dial lock. In principle, there was no need to create a locking mechanism of the cover, however, blocking the watch cover further increases the security of the watch, since it will not allow removing it to access the combination lock and unlock the setting/winding mechanism.

Blocking elements corresponding to the locking element are provided on an inner surface of the cover along the perimeter thereof.

The blocking elements corresponding to the locking element are preferably teeth or valleys.

The combination lock comprises at least 3 disks.

DETAILED DESCRIPTION OF THE DISCLOSURE

According to this invention, the watch with reference number 1, contains case 2 with removable cover 3 and watch face installed in case 2, activating the setting/winding mechanism. The clock mechanism can be both mechanical and quartz. Watch 1 is equipped with a combination lock indicated by reference number 4 used to block the setting/winding mechanism and block removing the cover 3 from the case 2 to prevent unauthorized use of watch 1.

The setting/winding mechanism comprises spindle 5 with clock winder 6 (crown).

In this particular embodiment, combination lock 4 is a dial lock mounted on a separate spindle 7, connected to the setting/winding mechanism by the lock bolt and a gear. For a person skilled in this art, it is clear that the implementation of combination lock 4 in the form of a dial lock is just an isolated occasion, which does not limit the scope of the patent protection of an invention. For example, combination lock 4 can be made in the form of a roller lock (see FIG. 12), a push-button lock, and other numerous devices that are clear and available to a person skilled in the art.

Gear 8 is mounted on spindle 5 of the setting/winding mechanism, and the dial lock comprises lock bolt 9 adapted to block gear 8.

Spindle 5 of the setting/winding mechanism in this embodiment has a portion with a square cross-section, and gear 8 is provided with corresponding opening 10 for fastening to the said portion of spindle 5 of the setting/winding mechanism.

Case 2 in this embodiment has a rectangular or square shape, and separate spindle 7 is parallel to spindle 5 of the setting/winding mechanism. It is clear to a person skilled in the art that case 2 can have the same round shape (see FIG. 4A). The other embodiment is identical to that with case 2 having a rectangular or square shape, with the exception that said separate spindle 7 shall be arranged at an angle with spindle 5 of the setting/winding mechanism.

Cover 3 is usually connected to case 2 with a threaded connection, with locking element 11 provided to block cover 3 in the closed position of the dial lock.

On the inner surface of cover 3 along the perimeter thereof, there can be blocking elements 12 corresponding to locking element 11, in the form of teeth or valleys.

The dial lock may contain at least 3 disks 13, depending on the implementation scheme and desired burglary resistance of the mechanism. It is clear to a person skilled in the art, that the more disks 13 the combination lock contains, the higher watch 1 security is.

The dial lock itself is a well-known tool and, therefore, this description will not include the code setting and opening.

It should be noted that after the correct dialing and opening of the dial lock due to the fall of the bar (not indicated by a reference number) of lever 14 into the corresponding openings (not indicated by a reference number), lock bolt 9 is released in disks 13 of the dial lock, which, in turn, unlocks gear 8, mounted on spindle 5 of the setting/winding mechanism, and the back cover of the watch, allowing the required operations with watch 1 (winding the watch, adjusting the hands, setting the date, etc.).

As mentioned above, combination lock 4 according to another embodiment may comprise, for example, a roller lock. This embodiment is shown in FIG. 12.

The roller lock may be arranged on a side surface of case 2 in proximity to spindle 5 of the setting/winding mechanism or on the exterior side of cover 3 of watch 1.

The roller lock comprises at least 3 disks. As with the combination lock, a person skilled in the art, will be aware that the more wheels 15 the roller lock comprises, the higher watch 1 security is.

Cover 3 in this embodiment is connected to case 2 by means of a threaded connection. It is clear, that cover 3 may also be connected to case 2 by means of screws or other suitable fasteners ensuring its fastening on case 2. The roller lock has lock bolt 9 to block cover 3 in the closed roller lock position.

Cover 3, in this embodiment, has a rectangular or square shape. A person skilled in the art understands that cover 3 may have a polygonal shape, for example. Cover 3 has a first end and an opposite second end, wherein a slot for engagement with a corresponding projection of case 2 is provided on the first end, and lug 16 for receiving lock bolt 9 of the combination lock 4 for blocking cover 3 is provided on the second end.

Thus, in its normal operating state, watch 1 is in a position where cover 3 of watch 1 is locked, and the winding of watch 1 or shifting the hands is impossible. To unlock watch 1, the user will need to dial the combination which is known only to him/her on combination lock 4, thus unlocking the setting/winding mechanism, as well as cover 3 of the watch.

According to another embodiment, the combination lock can be located on spindle 5 of the setting/winding mechanism, which is adapted to move along the axis thereof. U-shaped lock bolt 17 is arranged on spindle 5 of the setting/winding mechanism for engagement by a central part thereof with spindle 5 of the setting/winding mechanism and by legs 18 with guiding elements 19 in a plate of the clock mechanism, parallel to the axis of spindle 5 of the setting/winding mechanism to move the U-shaped lock bolt 17 along the axis of spindle 5 of the setting/winding mechanism together with spindle 5.

Spindle 5 of the setting/winding mechanism is adapted to move along the axis thereof between three positions:

(1) the combination lock blocking position (see FIG. 5) in which lock bolt 9 of the dial lock blocks U-shaped lock bolt 17 in the absence of engagement between winding pinion 20 and sliding pinion 21 and between sliding pinion 21 and intermediate wheel 22;

(2) the watch winding position (see FIG. 6), in which winding pinion 20 is engaged with sliding pinion 21 to ensure rotational movement of spindle 5 of the setting/winding mechanism with watch 1 winding in the absence of engagement between sliding pinion 21 and intermediate wheel 22 and absence of blocking of U-shaped lock bolt 17 by lock bolt 9 of the dial lock;

(3) the watch hand shifting position (see FIG. 7), in which sliding pinion 21 is engaged with intermediate wheel 22 to ensure hand shifting of watch 1 in the absence of engagement between winding pinion 20 and sliding pinion 21 and in the absence of blocking of U-shaped lock bolt 17 by lock bolt 9 of the dial lock.

Stem-winder bridge 23 of the clock mechanism, has three grooves on a working surface thereof, corresponding to the said three positions of movement.

Disks 13 of the dial lock may be arranged in a plane parallel or perpendicular to the plate.

The watch face may be provided with a window to display the locked and unlocked positions of the combination lock.

To display the locked and unlocked positions of the combination lock, it has indicator 24 associated with lock bolt 9 of dial lock 4.

Numeric display 25 of the combination lock is mounted on clock winder 6 (crown) or on the watch face (see FIGS. 8, 11).

Numeric display 25 of the dial lock is arranged on the watch face and associated to spindle 5 of the setting/winding mechanism by a pair of engaging gears located at an angle to each other (see FIG. 11), wherein one of the gears is mounted on spindle 5 of the setting/winding mechanism, and another engaging the numeric display of the dial lock.

The present invention is not limited to the above embodiments and is susceptible to various changes and additions without departing from the concept and scope of the invention, which is defined in the below claims.
