Description

  The present invention relates to a timepiece including a housing including an annular central portion and an annular bezel. In the present invention, the opening on the viewer side of the bezel is sealed by the cover glass, and at least one gong having a fixing gong foot is arranged to extend in the housing and can be struck with a hammer. It is.

  In this type of timepiece, it is known to fix the gong foot to the central part of the housing.

  Patent Document 1 (US Patent Application Publication No. 2008/0165630) discloses a timepiece in which a chime rod support is attached to a timepiece glass near a bezel.

  Further, Patent Document 2 (Swiss Patent No. 705114) discloses a timepiece in which a chime rod is attached to a central portion of a housing.

US Patent Application Publication No. 2008/0165630 Swiss patent No. 705114

  An object of the present invention is to provide a timepiece of the type described at the beginning, in which a gong is struck to generate a loud sound with high volume and high clarity, and the sound can be transmitted well to the outside. .

  This problem is solved by firmly positioning the gong foot on the bezel.

  Because the bezel is smaller in shape, it has a much smaller mass than the central part of the housing and the movement located in the central part, so the vibration attenuation in the gong is much greater in the bezel than in the central part and the movement. Small. Thereby, a loud sound with high volume and high clarity is generated.

  If the gong foot is arranged on the bezel, the number of parts can be reduced and the configuration can be simplified.

  The timepiece according to the present invention is preferably configured as a repeater timepiece.

  If all or part of the gongs extend parallel to the inside of the bezel, the required space can be reduced.

  The bezel can have a support surface that can be coupled to the side of the gong foot in order to better transmit vibrations from the gong foot to the bezel.

  In order to achieve an arrangement that allows the required space to be reduced by plunging into a part of the bezel, it is necessary to provide a holding recess with a radial side wall that opens radially inward and serves as a support surface. That's fine. In this case, the holding recess can be opened on the side opposite the cover glass in order to facilitate its manufacture.

  The gong foot may include a gong region that protrudes into the bezel and a fixed region that can be supported by the support surface.

  The gong foot can be easily attached to and detached from the bezel. Because the gong foot includes one or more through holes orthogonal to the side surface that can be supported by the support surface, a fixing screw reaching outward from the support surface can pass through the through hole, and the screw hole of the bezel It is because it is possible to conclude to.

  If a spacer is arranged between the gong foot and the support surface of the bezel and the thickness of the spacer is appropriately selected, it becomes possible to optimally adjust the height position of the gong foot and the gong relative to the hammer. A sound with higher clarity can be generated.

  The gong foot and the gong can be configured integrally.

  When the gong foot and the gong are made of a material block made of a single metal, since the fine structure of the gong and the gong foot material is the same, a loud sound with high sound volume and high clarity is generated.

  The striking hammer can be pivotally driven about a pivot axis arranged on the bottom of the housing or on the plate of the movement.

  In this case, one or more positioning elements are provided on the plate of the movement, and these positioning elements can be engaged with positioning recesses provided so as to correspond to the gong foot. In this case, it is possible to accurately position the gong and the striking hammer with respect to each other at the time of attachment, and thereby it is possible to adjust the striking hammer interval in an inoperative state with respect to the gong. This hammer interval is to ensure that the hammer is kept away from the vibration area of the gong after hitting the gong by the hammer and to avoid interference with the free vibration of the gong and the sound generated by the free vibration. Is important to.

  If the positioning element is configured as a positioning pin extending in the axial direction with respect to the bezel, and the positioning pin is engaged with a positioning hole formed in the gong foot in the axial direction with respect to the bezel. Easy to manufacture.

  If the striking hammer is disposed between the inner contour of the bezel and the gong and the gong extends in the striking hammer region so as to extend along the contour at the striking position of the striking hammer, it is surrounded by the gong. Sufficient space for placing other parts of the watch in the internal area can be secured.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

It is a bottom view of the bezel of a timepiece provided with a gong and a hammer. It is an expanded sectional view which follows the AA line of FIG. It is an expanded sectional view which follows the CC line of FIG.

  An annular bezel 1 of the repeater timepiece of FIG. 1 is formed with an annular groove 2 opened in the circumferential direction at an opening on the viewer side. A cover glass (not shown) can be fitted into the annular groove 2. Two holding recesses 3 and 3 ′ spaced apart from each other are formed in the radial direction of the bezel 1, and not only in the radial direction but also on the opposite side of the cover glass from the inside of the bezel 1. It is open.

  The side wall in the radial direction of the holding recess 3 functions as the support surfaces 4 and 4 ′.

  Each holding recess 3 is assigned a gong 6, 6 'that is formed integrally with the gong foot 5, 5'.

  The gong foot 5, 5 ′ includes a fixing region 9, 9 ′, which protrudes into the holding recess 3, 3 ′ and is held by the side surface 8 via the spacer 22. Supported on 3 'support surface.

  The gong foot 5, 5 ′ further includes a gong holding area 7, 7 ′ that protrudes radially into the inside of the bezel 1.

  Most of the gongs 6 and 6 ′ extend in parallel to the inside of the bezel 1, starting from the gong holding regions 7 and 7 ′.

  With respect to the movement, striking hammers 10, 10 'are mounted on a plate (not shown) extending radially relative to the bezel 1 so as to be pivotable about pivot axes 11, 11' extending axially relative to the bezel 1. In the non-actuated position, the striking areas 12, 12 'are spaced from the gongs 6, 6' over the hammer spacing. The striking hammer 10, 10 'in FIG. 1 is in a position where the gongs 6, 6' are hit.

  The gongs 6 and 6 ′ are two planes parallel to each other inside the bezel 1 starting from the gong feet 5 and 5 ′, and the hitting hammers 10 and 10 ′ disposed between the bezel 1 and the gongs 6 and 6 ′. It extends radially around the swivel region and then extends parallel to the inside of the bezel 1.

  In each gong holding region 7, 7 ', two positioning holes 17 are formed in a state separated from each other in the rotational direction. These positioning holes 17 extend in the axial direction with respect to the bezel 1 and have a configuration in which positioning pins arranged so as to correspond to the plates of the movement are inserted.

  Two through holes 13 and 14 are formed in the axial direction with respect to the bezel 1 in the fixed regions 9 and 9 ′ of the gong feet 5 and 5 ′ in a state of being separated in the rotational direction. The bezel 1 has two screw holes 15, 16 extending in the axial direction with respect to the bezel 1 on the support surfaces 4, 4 ′ of the holding recesses 3, 3 ′ in relation to the through holes 13, 14. .

  By inserting the positioning pins into the positioning holes 17 and fitting the gong feet 5 and 5 ′ into the holding recesses 3 and 3 ′, the through holes 13 and the screw holes 15, and the through holes 14 and the screw holes 16 are coaxially aligned with each other. To do.

  If the fixing screws 18 and 19 are passed through the through holes 13 and 14 and the through hole 23 of the spacer 22 from the bottom surface of the bezel 1 and fastened to the screw holes 15 and 16, the gong foot is formed by the flanges 20 and 21 of the fixing screw 18. The side surfaces 8 of 5 and 5 ′ are strongly pressed against the support surface 4 through the spacers 22. Thereby, the gong foot 5, 5 'and the gong 6, 6' are fixed to the bezel 1 in a state where the gong foot 5, 5 'is accurately positioned.
