Abstract

The invention concerns a digital display watch comprising at least two coaxial ring-shaped indicator disks (11, 12), driven in rotation of their common axis by a clock watch movement (20), said disks and said clock watch movement being housed in a case (2, 3, 4, 6, 9 ) having at least one aperture (1) running right through it in the axis direction. The invention is characterised in that said ring-shaped disks (11, 12) are arranged in a common plane, the outer disk (12) displaying minutes, being driven by means of a pinion (16) co-operating with teeth on the external periphery of said outer disk, and the inner disk (11) displaying hours, being driven by means of a pinion (14) co-operating with teeth on the internal periphery of said inner disk.

Description

Analog display watch

Technical field

The present invention relates to a kind of analog display watch (or pointer type wristwatch), comprise: at least two coaxial annular display discs, drive and rotate by watch movement around its common axis, these display discs and watch movement are placed in the watchcase, and this watchcase has at least one axially to extend to the opening of opposite side from a side.

Background technology

To notice opening or the hole of passing table of " opening " refer to of passing watchcase below from observing viewpoint see, it and any transparent element that can cover or insert in the open space have nothing to do, opening keeps open towards the visual field like this, and does not comprise any functional element of table.

The table of the above-mentioned type for example has been disclosed among the Swiss Patent No.680486.Yet the major defect of the table of this patent is to need an elongated relatively shape, has influenced the attractive in appearance of table to a great extent nocuously, and the thin people of those wrists is difficult to wear.And this table comprises the display disc of stack, like this instruction from above dish at least partially transparent make the pointer can see following display disc.

Purpose of the present invention particularly overcomes these shortcomings, and a kind of table is provided, and when described watchcase opening is arranged, can make this shape, and table is being reduced greatly perpendicular to the area on the plane of above-mentioned axle, so that table is more attractive in appearance and be more suitable for wrist.And, the invention is intended to provide a kind of display disc and pointer pattern of the table restriction of above-mentioned patent of not being subjected to improve its readable and demonstration aesthetic property.

For realizing above-mentioned purpose of the present invention, the invention provides a kind of analog display watch, comprise at least two coaxial annular display discs, drive around its common axis rotation by watch movement, described display disc and watch movement are placed in the watchcase, described watchcase has an opening of wearing along described direction of principal axis from a side to opposite side at least, it is characterized in that described annular display disc layout at grade, described outer dish is used for showing minute, by with the excircle of described outer dish on a pinion wheel of the collaborative running of tooth drive, described inner disc is used for showing hour, by with the inner periphery of described inner disc on a pinion wheel of the collaborative running of tooth drive.

Preferably, described watchcase comprises: the internal annular section that an external annular section and with internal spherical surface has outer annular surface, these two parts connect and are disposed opposite to each other by a transparent annular watch glass, and the outer and inner ring surface of this watch glass contacts with outer ring surface with the described interior of described watchcase respectively.

Preferably, described watch movement, gear train and display disc with its supporting member form can with the irrelevant assembly of described watchcase.

These embodiment especially make and can make watchcase with the device of common manufacturing watchcase, and the criterion in making according to the table base plate and the tolerance supporting member of making movable part.This greatly reduces manufacturing expense, and the independent test of gear train no longer is related with watchcase.

Description of drawings

Hereinafter the explanation of explanation and the embodiment that provides of accompanying drawing by way of example can be known other features, objects and advantages of the present invention, in the accompanying drawing:

Fig. 1 is the vertical view according to a wrist-watch of the present invention;

Fig. 2 is the cut-open view along the II-II line of Fig. 1;

Embodiment

The table that Fig. 1 and Fig. 2 roughly schematically illustrate has been showed an element with aesthetic feeling of characteristics with a form of passing the opening of opposite side from table one side.The shell of this table mainly comprises three parts round this opening, and promptly external annular section 2, internal annular section 3, the annular watch glass 4 that is connected with external annular section with internal annular section.Watch glass 4 is inserted between two ring surfaces, and just an internal spherical surface 5 forms with 2 one-tenth whole rings 6 of external annular section by one; With an outer annular surface 7, be formed on the excircle of internal annular section 3.

The watchcase of Xing Chenging has shown by one and has been fixed on the compartment 8 that the part 9 of this watchcase surrounds by bolt 10 like this.

The display device of this table comprises basic layout two annular display discs at grade, i.e. an inner disc 11 and a coaxial outer dish 12.

Inner disc 11 is provided with the pointer 13 of indication hour, and is driven by the pinion wheel 14 with the collaborative running of the internal tooth of this dish.

Outer dish 12 is provided with the pointer 15 of indication minute, is driven by the pinion wheel 16 with the collaborative running of external tooth of this dish 12.Pinion wheel 16 with take turns 18 coaxial pinion wheels 17 that drive by one and be linked to be integral body, this take turns 18 and pinion wheel 14 be positioned on the main shaft 19 of movement 20 of general table.Pinion wheel 16 and 17 is installed on the bridge shape part 21, and this bridge shape part is whole with 27 one-tenth of annular support members that is fixed on watchcase external annular section 2.Supporting member 27 comprises the supporting part that coils 11,12, as 22,23 and targeting part as 22 ', 23 ', dish 11 and 12 is placed in the top of the compartment 8 that part 2,3 forms with a kind of rotation mode.Supporting member 27 also can be used as a supporting member of watch movement 20, so that and the assembly that can irrespectively work with watchcase of movable part 11,12,14,16,17,18 common formation.

Accompanying drawing also illustrate can touch by the opening 1 of watchcase one on 24, two watchband coupling parts 25 of bar part and 26.

Pointer 13 and 15 can see by watch glass, and be show hour with respect to the scale of correspondence respectively and minute, for example on the one hand at the scale that forms on the visible face of the part 2 ' of annular section 2 and encircling the scale that forms on 6 the outside surface on the other hand.

Finding out significantly from this example according to table of the present invention has maximum area on the display panel plane that reduces size greatly, a design attractive in appearance that characteristics are arranged very much can be provided on the basis of the opening that passes this table simultaneously.Because the structure of this watchcase and comprise that the whole movement of all movable parts simply is placed in the watchcase, with this irrelevant fact of watchcase, the manufacturing cost of this table can reduce largely.
