Abstract
Abstract Push button-operated motion-control or display correction mechanisms in timepieces, especially chronograph- and stop watches in which at least one motion-transmitting member is arranged between a plate and a sensible member which is preferably a chronograph hand arbor, for cooperation with said button and said sensible member. A spring urges said motiontransmitting member towards its cooperating position with said button. The motion-transmitting member has two operating positions for different cooperation with said button. When a regular manual pressure force is applied to said button, the force as such will be transmitted from said button through said transmitting member when it is positioned at its first cooperating position, to said sensible member for effective position control thereof. When a substantial force is applied substantially larger than said manual pressure force upon said button, said transmitting member is positioned now at its second cooperating position under the combined influence of its substantial inertia and the resiliency of the spring will be blocked from its receding movement and the button movement checked through said transmitting member by a stationary member, preferably a watch casing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
219 words
A push button-operated display correction mechanism for a timepiece comprising a push button, a sensible member for indication of a certain time-related display, at least one motion-transmitting member operably arranged between said button and said sensible member for cooperation with said button and said sensible member, a buffer lever adapted to release or restrict the motion-transmitting member, said motion-transmitting member having a first position in which force from the push button is transmitted to the sensible member and a second position in which force is transmitted to the buffer lever but not to the sensible member, spring means urging said motiontransmitting member towards its cooperating position with said button, and means for bringing the motion-transmitting member to its first and second positions, a regular manual pressure force applied to said button being transmitted from saiD button through said motion-transmission member to said sensible member in the first position, when the buffer lever releases the motiontransmitting member and a sudden and substantial force substantially larger than said manual pressure force applied to said button being transmitted to the buffer lever in the second position of the motion-transmitting member when the buffer lever restrains the motion-transmitting member, the alternative actions of the buffer lever being determined by the combined influences of its inertia and the spring resiliency of said spring means.
Claim 2
Dependent Claim
219 words
A push button-operated display correction mechanism for a timepiece comprising a push button, a sensible member for indication of a certain time-related display, at least one motion-transmitting member operably arranged between said button and said sensible member for cooperation with said button and said sensible member, a buffer lever adapted to release or restrict the motion-transmitting member, said motion-transmitting member having a first position in which force from the push button is transmitted to the sensible member and a second position in which force is transmitted to the buffer lever but not to the sensible member, spring means urging said motiontransmitting member towards its cooperating position with said button, and means for bringing the motion-transmitting member to its first and second positions, a regular manual pressure force applied to said button being transmitted from saiD button through said motion-transmission member to said sensible member in the first position, when the buffer lever releases the motiontransmitting member and a sudden and substantial force substantially larger than said manual pressure force applied to said button being transmitted to the buffer lever in the second position of the motion-transmitting member when the buffer lever restrains the motion-transmitting member, the alternative actions of the buffer lever being determined by the combined influences of its inertia and the spring resiliency of said spring means.
Claim 3
Dependent Claim
82 words
The push button-operated display correction mechanism of claim 1, further comprising a stationary member, said buffer lever being arranged to partially enter into a space defined by and between said motion-transmitting member and said stationary member, and being capable of receding from said space upon application of a regular manual pushing effort upon said button and yet being squeezedly caught by and between said motion-transmitting member and said stationary member upon application of a sudden and substantial mechanical shock to said button.
Claim 4
Dependent Claim
122 words
The push button-operated display correction mechanism of claim 1, wherein said motion-transmitting member made as one body with said buffer lever is kept in engagement with a ring recess provided on said button and backed up by said spring means for performing a sliding movement in a direction substantially perpendicular to the moving direction of said button with said motion-transmitting member being adapted for engagement at its one end with a notch formed on a stationary positioning member, an engaging end of said motion-transmitting member acting as a pivot thereof upon application of regular manipulating effort onto said button, and said engaging end stepping over said notch without engagement therewith upon application of a sudden and substantial mechanical shock onto said button.
Claim 5
Dependent Claim
90 words
The push button-operated motion-transmitting or display correction mechanism of claim 1, wherein said one motion-transmitting member is slidable and pivotably mounted on said stationary member through a pin-and-groove connection, a second spring means being cooperable with said connection for stabilization thereof, a third spring means cooperable with said one motion-transmitting member and resilient forces exerted by said second and third spring means being so selected that by application of a sudden and substantial shock upon the button, the pivot of said member at said connection will perform a sliding motion.
Claim 6
Dependent Claim
66 words
The push button-operated display correction mechanism of claim 1, wherein the timepiece includes a base plate and said motion-transmitting member made as one body with said buffer lever is mounted slidably and pivotably on said base plate through a pin-and-groove connection, with the sliding direction being directed substantially at right angles to the axis of said push button, and spring means backing up said motion-transmitting member.
Claim 7
Dependent Claim
94 words
The push button-operated display correction mechanism of claim 1, wherein said motion-transmitting member made as one body with said buffer lever is slidable and pivotably mounted on said stationary member through a pin-and-groove connection, a second spring means being cooperable with said connection for stabilization thereof, a third spring means cooperable with said motion-transmitting member and resilient forces exerted by said second and third spring means being so selected that by application of a sudden and substantial shock upon the button, the pivot of said member at said connection will perform a sliding motion.
