Description

The utility model relates to means of attaching a strap or bracelet to watch cases, namely to a removable ear.

A removable ear for a watch case is known, comprising a tubular part in which a spring-loaded pin is located at least at one end (GOST 13649-79 Removable ears for a watch case).

Such a removable eye can be used only for watch cases having two opposite pairs of legs, i.e. double paws, while a fixture is required to install it.

Also known is a detachable eyelet for a watch case containing a tubular part provided with heads at both ends, at least one head being removable and provided with a shank fastened with a detachable connection to the tubular part (US 8002461 B2, 08/23/2011). This eye can be used both for watch cases having double legs with eyes and for cases with two diametrically located single legs with eyes. However, to install such a removable eyelet, an adaptation is necessary.

This utility model provides a quick connection of a strap or bracelet with double or single legs of a watch case without any additional devices, which simplifies the replacement of a strap or bracelet.

A removable ear for a watch case according to the present utility model comprises a tubular part provided with heads at both ends, at least one head is removable and provided with a shank fastened with a detachable connection to the tubular part, wherein the detachable connection of the shank of the removable head to the tubular part is made in the form of a bayonet mount with a lock.

In FIG. 1 shows a removable eyelet with a partial section;

In FIG. 2 shows a partial view of a watch case with a strap or bracelet mounted on it using a removable eyelet according to the present utility model.

As shown in FIG. 1, the removable eye comprises a tubular part 1 with a reverse axial groove 2, a removable head 3 with a shank 4 and a pin 5 designed to move along the reverse axial groove 2, and a fixed head 6. The shank 4 of the head 3 is installed with a stop in the locking spring 7, located in the cavity 8 of the tubular part 1. The locking spring 7 can be glued to the bottom of the cavity 8 to prevent it from falling out when the removable head 3 is removed. The tubular part 1 with a reverse axial groove 2, the removable head 3 with a shank 4 and a pin 5 and a locking spring 7 form b Quick-detachable connection, which is a bayonet with a lock.

In FIG. 2 shows a partial view of the case 9 of a watch with a single foot 10 (the second single foot is not shown), into the eye of which (not shown) and the eye 11 of the strap or bracelet 12 a detachable eye is threaded according to the present utility model.

To manually remove the strap or bracelet 12 from the single tab 10 of the watch case 9, press the head 3 with a shank 4 having a pin 5, overcoming the force of the spring 7, and by turning and axial movement of the removable head 3 while moving the pin 5 of its shank 4 in the opposite direction axial groove 2 of the tubular part 1 of the eyelet is removable, the removable head 3 is disengaged from the tubular part 1 and the removable head 3 is removed from the tubular part 1. After removing the removable head 3, the tubular part 1 with the fixed head 6 is pulled out of the eye of the single foot 10 the case 9 of the watch and the eyes 11 of the strap or bracelet 12, thereby separating the case 9 of the watch and the strap or bracelet 12.

In the inlet part of the reverse axial groove 2, bevels (not shown) can be made to facilitate this operation. Further, overcoming the resistance of the spring 7, push the removable head 3 with the shank 4 into the tubular part 1 while moving the pin 5 along the inverse axial groove 2 until it stops at the end of the inverse groove 2 under the action of the locking spring 7.

In the case of a wristwatch with double paws having eyes, the steps for removing and installing the strap or bracelet are similar to those described above.

If desired, the removable eye according to this utility model can be made with two removable heads, which simplifies the installation or removal of the strap or bracelet due to the quick connection / disconnection with the tubular part of any of the two heads and provides the ability to complete sets of heads with different decorative elements.
