Abstract

The retro styled display mechanism is provided with a star-wheel (1) mounted to a gearwheel (R2). The star-wheel (1) is provided with tip parts each having slopes (B and C). A clasp (3) is pressed against the slopes (B and C). The clasp 3 is mounted to a barrel (7) with a pointer (6) and a spring (2).

Description

Indication mechanism drives in the wrong direction
Technical field
The invention belongs to the clock and watch technology, particularly a kind of retrograde indication mechanism.
Background technology
The retrograde indication mechanism that is called the tooth bar display is known, and it is the pinion drive by short tooth depth.The included tooth bar of this class rack mechanism rotates on balancing shaft, and pointer is contained on the tooth bar.Tooth bar is bigger part, and this space that shows that this class mechanism occupies in clock and watch is bigger.Also knowing has many mechanisms to be made of the contact pilotage that contacts with snail wheel.Snail wheel rotates and concatenation pointer on balancing shaft.The information that will show is depended in the making of snail wheel, and its stroke has a straight-line segment when finishing, and makes contact pilotage can get back to its initial position under spring action.
The patent of invention content
The objective of the invention is to propose the retrograde reliably indication mechanism of a kind of little work that takes up space.
According to retrograde indication mechanism of the present invention, it is characterized in that it comprises star-wheel, be contained on the sprocket, this star-wheel is made of a lot of pointed tooths, is pressing a contact pilotage of fixing with pointer under the elastic force effect on the flank of each pointed tooth, and the information that will show is depended in the design of flank geomery.
In a preferred embodiment, contact pilotage, pointer and spring install on the barrel that rotates on the balancing shaft.This mechanism comprises a stop pin, and it can stop barrel to retreat and fall on the adjacent flank of another working cycle contact pilotage is covered its stroke along star-wheel pointed tooth flank after.
The flank of star-wheel pointed tooth, its shape and size can produce linear the demonstration.
Description of drawings
As an example, accompanying drawing illustrates an embodiment according to retrograde indication mechanism of the present invention.
In the accompanying drawing:
Fig. 1 illustrates the top view of this mechanism;
Fig. 2 is by holding the xsect of the balancing shaft of pointer in this mechanism;
Fig. 3 is similar to Fig. 1, but its retrograde contact pilotage is in the extreme position of pointer before resetting, and
Fig. 4 is the top view of retrograde star-wheel
Embodiment
Fig. 1～4 illustrate the part indication mechanism sketch that drives in the wrong direction, and in clock and watch, come indicating gauge with this display, are the power reserve amount of sweep second hand in this example.Its advantage is not beat.Different with the many retrograde measuring mechanism of prior art, pointer is at any time all in motion.
This mechanism comprises:
Star-wheel 1 drives in the wrong direction
Wind spring 2
Contact pilotage 3 drives in the wrong direction
Figure A20041000797900044
Wind spring fixed pin 4
Stop pin 5
Figure A20041000797900046
Pointer 6
This mechanism of driving in the wrong direction is by gear R1 and R2 transmission.The star-wheel 1 that drives in the wrong direction is attached on the gear R2 and several identical pointed tooths is arranged, and they are uniformly distributed along the circumference.
The end of retrograde contact pilotage 3 contacts and is pressed on the flank B of this pointed tooth with a pointed tooth of retrograde star-wheel 1 all the time.Wind spring 2 keeps this contact constantly.The xsect of balancing shaft A (Fig. 2) illustrates this mechanism's details, and wind spring 2 is contained on the barrel 7.Equally, drive in the wrong direction contact pilotage 3 and pointer 6 also is contained on the barrel 7.Barrel can freely rotate on balancing shaft A, and pin 4 is used for fixing wind spring 2.
During work, the motion thing R2 that drives in the wrong direction clockwise rotates, and promotes the tip of retrograde contact pilotage 3 by flank B.When this tip arrives the terminal point of its stroke (Fig. 3), flank separates with contact pilotage, and contact pilotage just drops on the next flank C.Such process repeats on next flank C.Therefore pointer is constantly in motion.Pin 5 plays stop pin in the process of dropping.And the end of anti-anti-retrograde contact pilotage 3 drops to the flute profile bottom of the star-wheel 1 that drives in the wrong direction.
Pointed tooth flank B, the C of retrograde star-wheel 1 is through well-designed, so that the pointer 6 that drives in the wrong direction moves linearly on the dial plate (not shown).
As shown in Figure 2, wind spring 2, retrograde contact pilotage 3 and pointer 6 are contained on the barrel 7, and are fixed on the relevant position of this barrel 7.
Wind spring 2 is tensioned and is fixed to by pin 4 on the housing of mechanism.As shown in Figure 1, near stop pin 5, and the contact pilotage 3 that drives in the wrong direction also contacts the pointed tooth flank B of the star-wheel 1 that drives in the wrong direction to pointer 6 when its stroke begins when its stroke begins.Along direction of arrow transmission (seeing Fig. 1 and 3), it is transmission contact pilotage 3 again conversely by motion thing R1 for the star-wheel 1 that is attached to gear 2, and contact pilotage 3 moves along this pointed tooth flank B of star-wheel 1 when gear R1 rotates.Pointer 6 is fixed with the relative position of contact pilotage, is overcome the effect transmission of spring 2 and is pointed out displayed value on the dial plate (not shown) by contact pilotage 3.When contact pilotage 3 exceeded position shown in Figure 3, spring 2 made contact pilotage 3 and pointer 6 get back to their initial position, is close to stop pin 5, and such working cycle begins on the flank C of star-wheel 1 again.
Can be used for pointing out the various information that clock and watch show usually according to the said mechanism shown in Fig. 1～4, as second, branch, hour, date, fate, month equate.Motion thing R1 and R2 must have suitable dimensions, and each pointed tooth of star-wheel 1 adapts with the plan displayed value.
The advantage of said apparatus is simple and can ceaselessly shows.When the pointed tooth of contact pilotage by star-wheel, next work period just begins, and demonstration is not interrupted continuously.

Claims (4)

1. indication mechanism drives in the wrong direction, it is characterized in that it comprises: star-wheel (1), on sprocket, this star-wheel is made of a series of pointed tooths, each pointed tooth has flank (B, C etc.), with the fixing contact pilotage (3) of pointer (6) under the effect of spring (2) near flank, the information that will show is depended in the design of the shape and size of flank (B, C etc.).
2. mechanism according to claim 1 is characterized in that, contact pilotage (3), pointer (6) and spring (2) are installed in can be on the barrel that rotates on the balancing shaft (7).
