Embodiment
Figure 1A shows the skeleton view of the core section of clock and watch of the present invention.Identical core section illustrates with side view in Fig. 2 A and Fig. 3 A, and illustrates with vertical view in Fig. 2 B and 3B.At this, as the situation in Fig. 1, the regulating shaft 16 in Fig. 2 A and Fig. 2 B is positioned at rotine positioning, and the regulating shaft 16 in Fig. 3 A and 3B outwards is adjusted to adjusting position vertically.If regulating shaft 16 is as being positioned at its rotine positioning as shown in Fig. 1,2A and the 2B, then movement normally moves.The details of movement function is known in those skilled in the art, is not theme of the present invention, thereby does not describe this details in detail.The meaning of the Reference numeral that does not elaborate below is referring to the reference numerals list relevant with description of drawings.
Shown in the side view of particularly Fig. 2 A and 3A, movement cross wheels 34 comprise two stacked, by disc spring 35 third wheel 34a connected to one another, 34b.Last third wheel 34a is connected with one fen wheels 40, and down third wheel 34b in power stream between driving wheel on barrel 10 and escapement 26.
The second wheel group 32 of movement is designed to two-piece type equally.At this, the lower member with second wheel 32a also in power stream between driving wheel on barrel 10 and escapement 26.Following second wheel 32 is same to be connected by friction---for example disc spring or thrust spring---is connected with last second wheel 32b, last second wheel 32b with return to zero heart shape spare 32c with second a 32d be connected in not relatively turnable mode.The top part of second wheel group---promptly goes up second wheel 32b, a zeroing heart shape spare 32c and a second axle 32d---and is connected with dividing wheels 40 by crossing wheels 34.
Under the bulged-in situation of table hat, an angular pole 18 with the 18a of tooth portion keeps a centre with the 20a of tooth portion to connect part 20, and the 20a of tooth portion is engaged among the 18a of tooth portion of angular pole 18.The centre connects part 20 and itself keeps adjusting zero rod 22 by second 20b of tooth portion again.At this, the 22a of tooth portion of adjusting zero rod 22 and middle second 20b of the tooth portion engagement that connects part 20.Adjusting zero rod 22 is divided into zeroing arm 22b and stopper arms 22c, and its function will describe when reference Fig. 3 B.If regulating shaft 16 is arranged in its rotine positioning, then two arm 22b, 22c remain on respectively in the inoperative position (neutralen Position).
Under the situation that the table hat is drawn out, i.e. when regulating shaft 16 is adjusted to its adjusting position (referring to Fig. 3 A and 3B) makes angular pole 18 swings, makes the centre that is engaged with connect part 20 by the 18a of its tooth portion then and rotates.By second 20b of tooth portion and adjusting range 20c, the centre connects part 20 makes adjusting zero rod 22 swings.Thus, the zeroing arm 22b of adjusting zero rod 22 presses against on the zeroing heart shape spare 32c that belongs to second wheel group 32, makes a second axle 32d move to zero-bit together with second hand and be fixed on the there.
Simultaneously, the stopper arms 22c of adjusting zero rod 22 not long ago discharged a brake rod 23 in the active region that arrives zeroing heart shape spare 32c, and brake rod 23 discharges a retarding spring 24 again, and retarding spring 24 stops escapement 26 and then stops movement then.
Thereby must approaching, the zeroing arm 22b decision design of adjusting zero rod 22 has elasticity.Come the power that zeroing arm 22b is affacted on the zeroing heart shape spare 32c is measured by this elastic construction, select to the accurate shape of zeroing arm 22b and then to (associated) elastic force, so that the zeroing of unshowned second hand is in the accompanying drawings worked reliably, and can not damage second hand group 32.By connect between part 20 and the adjusting zero rod 22 the special 20b of tooth portion, the 22a that is provided with in the centre, the torque that the elastic force by zeroing arm 22b is formed no longer is passed to angular pole 18.Therefore, can make regulating shaft 16 and then the table hat is rotated without a doubt with the adjusting watch time, and can not make regulating shaft 16 automatically get back to rotine positioning once more.
When rotating regulating shaft 16, the minute hand (not shown) is rotated by minute wheel 43.At this, the rotation of regulating shaft 16 is delivered on the minute wheel 43 by corresponding train (and other back gear 36) in known manner.Locking mechanism by the branch wheels 40 that clearly illustrate at Fig. 4 A, 4B and 4C is realized this from the multiple step format motion of a scale division to next scale division.Shown in Fig. 4 A, 4B and 4C, be provided with a kayser circle 44 concentric with centre wheel 42, wherein the overall diameter of kayser circle 44 is slightly less than the overall diameter of the centre wheel 42 that externally forms tooth.Kayser circle 44 can not be connected (referring to Fig. 4 B) with minute wheel 43 with relatively rotating, and kayser circle 44 has 60 kayser teeth 45 on interior week.Kayser tooth 45 is with 46 coefficient mode regulation minute wheels 43 and then 60 possible positions that be minute hand with two positioning handles.Two positioning handles 46 are bearing on the fulcrum post 47 of centre wheel 42 in the mode that can swing respectively.One installs the thrust spring 48 that is designed to two for simplification is arranged on the centre wheel 42, this thrust spring 48 is the ends that oppositely are provided with fulcrum post 47 of two positioning handles 46 of pushing outwards, so that the surface of contact 46a of two positioning handles 46 abuts in respectively on the kayser tooth 45 of kayser circle 44.
If under the situation that table hat is drawn out, rotate regulating shaft 16, then make minute wheel 43 be connected and make the train that minute wheel 43 is connected with regulating shaft 16 with kayser circle 44 and utilize positioning handle 46 rotations with respect to centre wheel 42 through back gear 36.Because 32c is locked for zeroing heart shape spare, centre wheel 42 is crossed wheels 34 lockings (referring to Fig. 3 A and 3B) at this.At this, the power that kayser tooth 45 overcomes the spring part 48 of outside pushing positioning handle 46 radially inwardly pushes positioning handle 46, and positioning handle 46 slides along corresponding kayser tooth 45 with surface of contact 46a, thereby makes minute wheel rotate 1/60 before positioning handle 46 is again by next kayser tooth 45 kaysers.Therefore only can be to regulate minute hand from a scale division to the mode of next scale division step by step.
If will show hat and then regulating shaft 16 will be pressed into its rotine positioning (referring to Fig. 1, Fig. 2 A and Fig. 2 B) again, connect part 20 in the middle of then angular pole 18 moves.By connect the 20b of tooth portion between part 20 and the adjusting zero rod 22, the engagement of 22a in the centre, adjusting zero rod 22 is got back to inoperative initial position once more.The zeroing arm 22b of adjusting zero rod 22 is released in the zeroing heart shape spare 32c on the second wheel group 32 once more.Stopper arms 22c by adjusting zero rod 22 gets back in its inoperative position brake rod 23 equally simultaneously, and makes retarding spring 24 pendulum from escapement 26, and escapement 26 is released again, and movement restarts.
The friction that makes the lower member 32a of two third wheel 34a, 34b and second wheel group be connected to upper- part 32b, 32c, the 32d of second wheel group connects and is used for seamlessly starting minute hand and second hand.In (the effect and) operation of starting from scratch because null setting of this second hand, minute hand then brings into operation from a scale division owing to locking mechanism (effect).Therefore two pointer synchronous operations.
