Description

Wrist-watch

The present invention relates to a kind of wrist-watch, it has a watchcase that is equipped with a rotatable outer ring, the endless member that is profile of tooth, a clockwork spring turning handle, it limits the cross section and is interlude outside the device that polygon is positioned at, the transmission gear that the opening of cross section and the complementation of interlude cross section is arranged on it, and this transmission gear and interlude coincide mutually, its gear teeth and above-mentioned that endless member that is profile of tooth are meshed, and so just form kinematic chain between rotation outer ring and clockwork spring swing handle.

The explanation of this wrist-watch has seen in the patent application specification of open CH1825 number and CH72852 number of Swiss Patent.In each above-mentioned suggestion design proposal, this rotary outer ring all is meshed with a gear, this gear is combined in again on the lever so that it can be optionally with rotary outer ring optionally with the spring box in clockwork couple together, or couple together with the train of time set.

These schemes all need the device of his-and-hers watches comprehensively to change, and like this, have only the table that has been equipped with this device to screw clockwork spring by rotary outer ring.

In the CH66235 patent document, another kind of design proposal was proposed also.Rotary outer ring in this scheme has the gear teeth, the gear teeth on the one hand be meshed in conjunction with transmission gear of clockwork spring swing handle, on the other hand then when one is installed in establishing on the accessory plate gear of device be meshed.The purpose of this scheme can be installed by rotatable outer ring exactly and be winded up and device and need not change its mechanical hook-up when establishing, and the extra assembly of installing on the accessory plate that only need suspend gets final product.

But such table has inconvenience.Because it needs an accessory plate and a cover additional mechanism, so in fact increased the height of mechanical hook-up.In addition, if wind up a watch simultaneously, will drive the time set lever, when rotation surpassed certain angular range, the time set lever will make a deflecting roller and the engagement of the transmission gear on the time-setting mechanism supported by this lever.Therefore, if the angle the when user rotates clockwork spring has because of carelessness surpassed this outer ring rotation angle range, will cause the change of time, yet in fact just tighten clockwork spring on his intention.

Other utilize the outer ring to tighten clockwork spring and system specialization that the time is set sees CH-A-316834 number and the CH-A-65378 patent document in.In both of these case, the transmission gear that is meshed with crown on the rotatable outer ring combines with the clockwork spring turning handle fully by rotation and translation.These two documents first in, the displacement of clockwork spring turning handle slightly is separated the tooth of transmission gear and the crown on the outer ring, so very easily makes these gear teeth damaged.And the do not have such shortcoming in the two because it has correspondingly increased the width of crown so as on two axial locations of swing handle and the transmission gear of clockwork spring turning handle be meshed.Yet this scheme is the clock of buying car in installments on the instrument panel to be used, and is not suitable for wrist-watch, because it need increase the thickness of gear ring, thereby can destroy the specious of watchcase.

The cross section of the interlude of clockwork spring turning handle is set to square so that it can drive the clutch transmission gear on all axial locations, to tighten clockwork spring or setting-up time, this be since a century in various clock and watch systems the most common way, but in this example, problem and not lying in is kept in the axial direction fixing of rolling transmission gear.On the contrary, rolling transmission gear pull-out element and lever when establishing move towards the direction opposite with the clockwork spring turning handle, are meshed with deflecting roller in the time-setting mechanism making it.

Purpose of the present invention is exactly to revise above-mentioned defective at least in part, and make by people think always a kind of loaded down with trivial details running program and now automatically and winding up of no longer adopting in the electronic watch become a kind of people and be willing to and the Cup of tea feelings, because this clockwork is with usually different by the keyless wrist-watch of clockwork spring, it makes people to tighten clockwork spring more easily under wrist-watch still is worn over the situation of wrist.As we will see in the following description; except the pure mechanical technique imagination that clockwork has been done; also taked some other measure to protect it, made it not to be subjected to dust to damage, sealed a long serviceable life to guarantee outer ring and protection.

For this reason, object of the present invention is exactly the wrist-watch of an above-mentioned form.Its characteristics are, described transmission gear is set on the axis direction between two limited blocks that are combined on the watchcase, and the described interlude of the polygonal cross-section of clockwork spring turning handle has selected length, thereby described turning handle can axially moved at least between two positions, a position is used to wind up, the another location then is used for setting-up time, simultaneously, also keeps kinematic chain between outer ring and the clockwork spring turning handle by described transmission gear.

According to other characteristics of the present invention, what is particularly worth mentioning is that: the clockwork spring of a common wrist-watch that manually winds up is replaced by the slip clockwork spring in the wrist-watch that is usually used in winding up automatically.Specifically, rotary outer ring can apply the moment of torsion that obviously can apply greater than the clockwork spring turning handle on clockwork spring.Therefore, a very big advantage of this wrist-watch is exactly: be tightened into the position in case drive clockwork spring, it just can slide in the spring box, like this, is screwed fully although clockwork spring is own, but still can ceaselessly rotate the outer ring and can not cause the damage of clockwork spring.

Since in this case, the action that clockwork spring screws is not stopped, and the user does not just know whether clockwork spring is screwed so.Therefore, if add an indicator again, show the degree that screws (this is a known devices) that drives clockwork spring, this will be again an advantage so.

According to wrist-watch of the present invention, with regard to mechanical hook-up itself, do not need to make any modification.The place that a unique place need revise is exactly the position of clockwork spring turning handle, therefore, owing to there has been the present invention just might under the prerequisite that only changes the clockwork spring turning handle, be applied to any clock and watch to native system.

Following accompanying drawing is the simple diagram to one embodiment of the wrist-watch of design according to the present invention.

Fig. 1 is the axial partial sectional view of this wrist-watch.

Fig. 2 is the local up-sizing figure of Fig. 1.

Table shown in the figure comprises a mechanical hook-up 1 that is covered by dial indicator 2, and it is positioned at a watchcase, and this watchcase also comprises a gear ring 3, bottom 4 and glass 5.

An annular recess 6 is arranged at the bottom that the top of gear ring 3 is formed by an endless groove 7, one can revolve outer ring 8 and be embedded among the annular recess 6, and fixed in the axial direction by the pin 9a as screw 9 ends, and this pin 9a radially passes around outer ring 8 and the annular distribution.Pin 9a is embedded among the annular groove 10 on the side of annular recess 6.An annular groove 11 that is parallel to annular groove 10 is used to hold O shape annular seal 12.Second seal 13 is positioned among the annular groove 23 in 8 lower surfaces of rotary outer ring.As shown in Figure 2, seal 13 preferably has a semicircular cross-section, and its level and smooth one side is combined in the bottom of groove 23 with bonding agent, the shape of seal 13 and so bondingly can prolong its serviceable life, and rotatable outer ring is rotated to either direction.And as for seal 12, O type shape annular seal preferably then.

The lower surface of this rotary outer ring 8 also has the endless member 8a of a protrusion, and a dentation side 8b is arranged in its end, and endless member 8a is arranged within the endless groove 7.

Groove 7 and a column 14 communicate, and the axis of its rotation and clockwork spring turning handle 15 coincides.Clockwork spring turning handle 15 comprises the interlude 15a with square-section, and it passes one and has same cross section, concentrates on the opening on the axis of a transmission gear 16 that is meshed with gear teeth 8b.An involution member 17 has a pipe 18 on it, be furnished with an O shape sealing gasket 19, in order to the motion that matches of the protruding button 20 of clockwork spring.This involution member 17 is fixed in the column 14 by two screws (not shown) that are fixed on the gear ring 3 in clockwork spring turning handle 1 both sides respectively.Therefore, transmission gear 16 axially is fixed between two limited blocks of being made up of the medial surface of column 14 bottoms and involution member 17.The latter's side has its inside that the groove 17a of one O shape sealing gasket 24 is arranged, and is positioned in the either side of transmission gear 16 in case stumbled by other members by two distance pieces 21 making as nylon and 22.Because such make, the interlude 15a with square-section of clockwork spring turning handle 15 just can freely slide in the opening of transmission gear 16, and transmission gear 16 keeps being meshed with the gear teeth 8b of rotatable outer ring.Therefore, clockwork spring turning handle 15 just can be in two or three different positions, for screwing clockwork spring, setting-up time or date, as same common clockwork spring turning handle, simultaneously, between rotary glass disk 8 and the clockwork spring turning handle 15 by by the interlude 15a rotatory ground of square-section keep constant kinematic chain in conjunction with the transmission gear on the turning handle 15 16.

Can see thus, in above-mentioned clock and watch system, need not to make any modification or interpolation and destroy its integrality that unique place that needs to revise is exactly watchcase and that part that is in the clockwork spring turning handle outside the mechanical hook-up.Therefore, the way of such tool advantage equally also is in order unrestrictedly to rotate rotation outer ring 8 to increase user's enjoyment, just to be to use a big clockwork spring as in automatic watch.So just can avoid driving the wearing and tearing and the destruction of clockwork spring.

We equally also can see, clockwork spring and timing device because of seal can be fully not water soaked the damage of dying with dirt, it is impaired to make that thus wrist-watch avoids, and prevents from equally again to be stumbled by outer ring 8 and transmission gear 16 these movable parts.

The dress box process of this wrist-watch only is the slight modification to general wristwatch.After mechanical hook-up is loaded into watchcase, before tightening up bottom 4, clockwork spring turning handle 15 is in place by common way, with the same in other tables, the screw (not indicating) that screws of pull-out element is fixed.Then, only need transmission gear 16 is axially inserted and make it the interlude 15a joint of the square-section of turning handle therewith, then, put into involution spare 17 and use two screws (not marking) that are positioned at clockwork spring turning handle 15 both sides that it is fixed on the gear ring 3.Next rotary outer ring 8 then need be installed and clench gib screw 9,, like this, just can wind up and timing according to the axial location driving transmission gear 16 and the clockwork spring turning handle 15 of clockwork spring turning handle 15 so that rotary outer ring 8 is positioned on the gear ring 3.
