Problems solved by technology

However, in order to prevent the hammer from wasting energy when it strikes the gong, this hammer arrangement complicates the manufacture of the striking mechanism, which is a disadvantage
Another disadvantage is that the hammer may bounce against the gong in an undesirable manner during the strike

Embodiment Construction

[0015] In the following description, all the components in the striking mechanism of the watch and the timepiece movement known in the art will only be briefly described. The focus is primarily on the arrangement of the spring element including the stop element of the striking mechanism. The stop element ensures an increase in the striking speed of the hammer with less wasted energy of the hammer and improves the safety against any rebound of the hammer against the gong.

[0016] figure 1 and 2 A simplified view of the striking mechanism 1 of the watch is shown, with its various components mounted in a conventional manner on the main plate, which is not shown in order to avoid complicating the drawing. This striking mechanism 1 comprises at least one gong 21 fixed at one end thereof to a gong support 22 integrally formed with the main plate of the watch, not shown. Gong 21 in figure 1 and 2 The other end, not shown, is usually free to move. The gong 21 can be made in the...

Abstract

The strike mechanism (1) of a watch includes a gong (21), which is secured by one end thereof to a gong-carrier (22) integral with a plate, a hammer (2) rotatably mounted on the plate for striking the gong (21) at predetermined times, a damping counterspring (5) for keeping the hammer at a distance from the gong (21) in an idle mode, and a spring (3) for driving the hammer. The drive spring includes one end (3b) secured to the plate and one end (3a) that is free to move. The spring is capable of being wound so as to drive the hammer (2) against the gong (21) in a strike mode to generate an acoustic sound. The strike mechanism further includes a stop member (10) on the path of the hammer drive spring in the direction of the gong for increasing the strike speed following contact of an intermediate part of the drive spring (3) in action against the stop member.

Description

technical field [0001] The invention relates to a striking mechanism for watches. The mechanism comprises at least one hammer arranged to strike at a determined moment at least one gong fixed to the gong support. The hammer is fixed at a certain distance from the gong by the damping spring in idle mode. The spring of the hammer in the drive mechanism can be arranged in the form of an elastic sheet or an elastic beam. The drive spring may be wound to drive the hammer against the gong to provide, for example, a sound signal for a preset time period. Background technique [0002] In the world of watchmaking, a striking mechanism can be combined with a regular watch movement to act as a minute repeater or to indicate a preset alarm time. A striking mechanism of this type usually comprises at least one gong made of a metallic material such as steel, copper, precious metal, metallic glass, sapphire or quartz. The gong may represent at least a portion of the circle surrounding ...
