Therefore, fundamental purpose of the present invention is to remedy the aforesaid drawbacks of prior art, meter comprises stem instrument bezel being associated with pawl device and it is fixed on device on the watch shell when providing a kind of, with comprise the assembly structure of bezel in watchcase circle portion, it can make bezel with respect to watchcase circle portion and watch glass centering effectively, and give substantially constant of bezel anti-torque, it is simple and economical also having it to use the conventional manufacturing technology in this area, make.
Therefore meter comprised a stem instrument bezel when another object of the present invention was to provide a kind of, and its mechanism can prevent that solid impurity from entering, and can be used for any environment and did not influence the inherent function of bezel.
So, the present invention relates to a kind of time meter, comprise a shell with watchcase circle portion, a bonnet, a watch glass that is fixed in the watchcase circle portion, rotate a rotary type bezel that leads with respect to watch crystal and watchcase circle portion, be used for said bezel is fixed on device in the watchcase circle portion, and be associated with bezel comprise one be installed in bezel in the detent mechanism of the ratchet spring that cooperates of tooth, it is characterized in that: packing washer is installed on the detent mechanism between bezel and the watch glass, said packing washer guarantee bezel with respect to watch glass centering and frictional restriction power to stop the rotation of bezel.
Therefore, packing ring is installed directly between bezel and watch crystal, is made that bezel has constant anti-torque basically, just in case ratchet is on the rotation direction of its permission, can not guarantee the maintenance of bezel, if need, can balanced have the flexibility of spring of ratchet.Moreover the installation that above-mentioned packing ring is specific makes bezel with respect to watch glass centering, therefore, exists very little activity between these two members, thereby, stoped impurity to penetrate on the one hand, on the other hand, the aesthetic feeling of meter when having improved.
According to the specific embodiment of the invention, watchcase circle portion divides at an upper portion thereof and comprises a sleeve, and stationary installation comprises and is placed at the split ring that plastic material is made in the 1st recess that bezel partly constitutes, with when bezel in watchcase circle portion during installation in position, this split ring is configured in the outside surface of said sleeve.
Owing to adopt said structure, bezel be axially fixed on the sleeve and can be easy to, and may reach economically by simple split ring.
According to favorable characteristics of the present invention, this sleeve, exterior section comprises an oblique section thereon, its footpath is extended by column part, has the annular radial groove in column part, partly constitutes first notch part in its underpart via a shoulder therebetween.
Therefore, by split ring being placed in the groove of bezel, force bezel to be contained on the sleeve then, when when the conical surface, split ring expands to be opened, and can realize being installed in bezel on the sleeve simply and with its axial restraint.Be noted that the dismounting that in above-mentioned situation, can be easy to finish bezel by the split ring that fractures.
By providing the reading that following examples describe in detail with reference to illustrative shown in the drawings and non-limiting example, other advantage of the present invention and feature will be apparent, wherein:
Fig. 1 represents according to time meter partial cross section view of the present invention;
Fig. 2 represents to be used for the spring section top view that has each ratchet of meter when shown in Figure 1;
Fig. 3 is the spring section partial side view that has each ratchet of Fig. 2; Represent a spring leaf that constitutes detent mechanism more specifically.
With reference to accompanying drawing, meter when of the present invention will be described below shown in the label 1.
Time meter 1 is equipped with shell 2 and comprises watchcase circle portion 4, bonnet 6 and watch glass 8, and wherein hold the movement 10 that dial plate 12 is housed on the top.In this illustrated example, watch shell 4 and bonnet 6 are to be made by single derby.
On watch shell, arranging has outstanding rod 14, be used for the time meter and the (not shown) that is connected watchband.
In this example, watch glass 8 is to be made by plastic material, and by welding or glued joint, via the following peripheral part, directly be fixed on the synthetic rim 16 of movement 10.Rim 16 is clamped between the fixed surface separately 18 and 20 of watch shell 4 and sleeve 22, and this sleeve 22 is engaged on the shoulder of watch shell via lower flange 24.Packing washer 26 is inserted between rim 16 and the surface 18, to guarantee the sealing of this shell to the outside.Therefore, watch glass 8 is fixed on the watch shell 4.
Sleeve 22 have an inner cylinder face 28 subsequently shoulder form 20 and following faces of cylinder, surface a little outwards broadening form flange 24.
Outer thereon part, sleeve 22 have an oblique section 30 on column part 32, form annular radial groove 34 in this part.More down, sleeve 22 part therebetween has a shoulder 37, and its not hold be flange 24.
Time meter 1 also has a stem instrument bezel 36, for example is made of metal, and it rotates guiding with respect to watch crystal 8 and watch shell 4.Bezel 36 has one to be opened to 42, one the annular radial grooves 44 of interior axial tooth that have sawtooth than 38, one on the 1st face of cylinder on the 2nd garden cylinder 40 of the 1st larger diameter, and an axial restraint surface 46.
Watch glass 8 has a shoulder that is provided with the peripheral side of annular groove 48 and limits axial restraint surface 50.According to feature of the present invention, annular groove holds a packing washer 52, and configuration is basically facing to the face of cylinder 38.Annular groove 48 preferably has a ring section, and packing washer 52 is packing rings of a kind of elastic body double-curved surface form.
Should be noted that need only control loop connected in star 40 and 48 size so that obtain the desirable compression of packing washer, it is easy to finish by conventional manufacturing technology.As a result, can control the torsion that stops bezel to rotate well.
Inner cylinder face 28 limits a said recess that is located at shoulder in the watch glass 8, and the spring that has each ratchet wherein is housed, or ratchet spring 54.
More particularly, annular ratchet spring 54, seat is in the axial surface and the rotational fixation of shoulder 50, for example, by being pressed into, or be glued on the watch crystal, or by the notch E that provides in the spring with each claw that cooperates with it, or be provided at the side of watch crystal 8 for this purpose, or opposite.
Spring 54 in the example that specifically describes in Fig. 2 and 3, has 6 ratchets 56 of the spring leaf shape of can axial bending and matching with the tooth 42 of bezel 36, therefore, constitutes the detent mechanism that matches with bezel 36.
In above-mentioned example, ratchet spring 54, more particularly each ratchet 56 is made by plastic material.When bezel rotates, particularly when the latter be that above-mentioned situation had the danger of the tooth 42 of eliminating any damage bezel 36 when for example aluminium or acieral were made by " soft " metal.Spring 54 be by, for example, the plastic material that the high-elastic limit is arranged, be preferably in 160 to 200 megabars), make o as an example, optimal is to be called 6.6 polyamide that 40% carbon fiber is arranged that Si Lani phase nylon (Celanese Nylon) is sold by milli this spy (Hoechst) company.
Because the friction factor of plastic material on metal, relatively little natively, so should note, on the direction that detent mechanism allow to rotate, make bezel rotate that institute must torsion be decided by to act on the one hand basically between watch glass 8 and packing washer 52, certain to the friction force c that acts between the latter and bezel 36 on the other hand, ratchet spring 54 also can be made of metal.
According to feature of the present invention, on the detent mechanism of bezel 36, packing washer 52 is housed, thereby when bezel (36) rotated: packing washer 52 can prevent that any solid impurity that can damage this mechanism from penetrating.
Centering of bezel 36 directly finished on watch crystal via packing washer 52.Therefore, the face of cylinder 38 of bezel 36 and gap between the watch glass 8 or activity 58 can be very little, for example along between 0.10 millimeter and 0.20 millimeter of the radius.So outside thing makes the danger that enters this slit, has in fact got rid of.Moreover, by packing washer with bezel to the center, make the radial wobble of bezel in fact eliminate, so the table that bezel is housed has high-quality visual impression.
Bezel 36, in watchcase circle portion 4, the axial restraint device is housed also.These stationary installations comprise a split ring 60 that is contained in the groove that part forms in the bezel 36, and when bezel 36 was in place in watchcase circle portion 4, split ring 60 were contained in the outside surface of sleeve 22.More precisely, split ring 60 is the rings that the plastics with rectangular cross section are made, and its radial dimension is greater than axial dimension, and common name " flat " resilient ring.Best, the resilient material of selecting to have anti-high shear resistance is used to make split ring.A kind of quite suitable with the ratchet spring identical materials.
Therefore, recess has the square cross section, by being separately positioned on the radially annular groove 34 and 44 in sleeve 22 and the bezel 36, forming the recess split ring 60 that faces with each other is installed in this recess, thereby, it extends in groove 34 of sleeve 22 and in the groove 44 of bezel 36 in normal place shown in Figure 1.Yet advantageously radially activity allows it via in the elastic expansion shift-in groove 44.
For bezel 36 is assemblied on the watch shell 4, at first ratchet spring 54 is placed on the surface 50 of watch glass 8, then packing washer 52 is installed in the annular groove 48, then, utilize bezel 36 pressure on sleeve 22 to mesh, because radially activity arranged necessarily, before be contained in the split ring 60 in the annular groove 44 of bezel 36.At this moment, the inside surface of ring 60 contact with oblique section 30, and slip elasticity is opened on the latter, but enters its release position up to reaching opposite groove 34.In case unclamp, the expansion of split ring 60 parts enters groove 34 and 44, and in fact the axial surface 46 of bezel contacts with shoulder 37 surfaces of sleeve.
In case emplace, bezel can only axially be carried pulling down and unavoidably break split ring.When bezel was ressembled, this not expensive part can be replaced.
