Fixing device for fixing heel of striking gong on middle part of watch by using screws, has heel comprising support faces forming angle between faces that are engaged with contact faces of middle part of timepiece

摘要

#CMT# #/CMT# The device has a heel (3) comprising first and second support faces forming an angle between the faces. The support faces are engaged with contact faces (13, 14) of fixed part i.e. middle part (12), of a timepiece. Clamping elements e.g. screws (17), exert pressure in a direction perpendicular to the support faces. The support faces of the heel and the contact faces of the fixed parts are orthogonal to each other. The screws traverse the heel according to orthogonal directions, and are screwed into threads in the contact faces. #CMT#USE : #/CMT# Fixing device for fixing a heel of a striking gong on a fixed part i.e. middle part of a timepiece i.e. watch, by using clamping elements e.g. screws. #CMT#ADVANTAGE : #/CMT# The device screws the heel of the striking gong into the fixed part of the timepiece to form a connection with maximum rigidity at maximum contact pressure according to orthogonal directions, so as to improve transmission of the vibrations from the gong to the fixed part of the timepiece. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of a fixing device. 2 : Collar 3 : Heel 12 : Middle of timepiece 13, 14 : Contact faces 17 : Screws.
