Description

Field of the invention

The invention relates to an accumulator mechanism for mechanical watch with reduced bung diameter.

The invention also relates to a watch movement comprising at least one such accumulator mechanism.

The invention also relates to a timepiece comprising at least one such movement and / or at least one such accumulator mechanism.

The invention relates to the field of watchmaking, and more particularly the field of energy storage barrels, for feeding a movement, a ring, or other functionality of a timepiece.

Background of the invention

To increase the power reserve, by increasing the number of turns of a mainspring, a solution consists of a decrease in the diameter of the barrel shaft and the associated bung, so as to increase the available space in the drum for the spring.

The ratio of the bead radius with respect to the thickness of the spring is usually between 10 and 20, and the invention proposes to lower this ratio below 10, and preferably in the range between 5 and 10. and 10.

The dimensioning should not be done lightly, indeed a risk of breakage exists if the diameter of the plug is too small.

In the conventional architecture of the barrels, a ratchet is mounted axially on a barrel axis or on a bung, via a square, the ratchet being generally fixed by an axial screw. The size of this screw and that of the square thus condition a minimum diameter of a pivoting surface. A shoulder abutting with this pivoting surface limits axial fretting of the shaft or the bung relative to a plate or bridge carrying a stone or the like.

[0009] A diameter even greater than that of this shoulder is necessary for a pivoting guide surface of the drum on the shaft or on the bung, combined with a shoulder for limiting the axial frustum of the drum. The respect of minimal sections of matter implies a quotation chain which results in a large size, difficult to reduce. In particular, it is not enough to reduce all the sizing, because the sections of material are then insufficient to ensure fatigue resistance.

Detailed Description of the Preferred Embodiments

The invention relates to the field of watchmaking, and more particularly the field of energy storage barrels, for feeding a movement, a ring, or other functionality of a timepiece.

The invention takes into account several solutions to achieve a decrease in bung diameter, which allows to increase the energy stored in the barrel.

The different routes proposed by the invention can be combined together, to obtain an optimal result depending on the available space, the position of the ratchet, the presence or not of a lid for closing the barrel this function can also be assigned to the ratchet.

A first solution is to ensure the frolicking between the drum and lid by the mainspring, transferring the spring to this frolicking adjustment function, in particular by equipping the spring protruding areas, such as emerge, larger laminated areas, reported flange, or the like. It is then possible to remove the bearing shoulders of the drum and cover on the barrel shaft or on the bung.

A second solution is to make a bung in several parts, in particular in two or three parts. This solution makes it possible in particular to make a bung of diameter smaller than the pivoting diameter of the drum. Advantageously, the plug is introduced through the bore of the drum. A shaft or a bung in two parts, or more, facilitates the machining of hook of hook of the shell of the mainspring.

The bung may include, for driving the ratchet, a conventional square, or a thread. Or, in a non-limiting way, in a second variant the bung may further comprise one or more washers or catch-up diameter rings for its guidance in platinum and bridge.

Another solution is to hunt on the bung a setting washer of the drum-lid frolicking. This washer is mounted so as to avoid, for an intervention on the cylinder, any disassembly of a bridge.

Another solution is to provide pivoting in the bridges for the drum and / or the lid, instead of performing this pivoting at the barrel shaft or the bung. Advantageously, both the drum and the lid are pivoted in a plate and a bridge.

The various variants provided by the invention ensure ease of machining, ease of assembly, ease of disassembly, and control of axial debates between the various components and with respect to the bridges.

Two types of frolics are to be considered: the frolic of the barrel "alone", on the one hand, the frolicking of the barrel with the blank or drafts, hereinafter reduced for the simplicity of the presentation and in a nonlimiting manner to a plate and a bridge, on the other hand.

These antics add up and we must take into account these two frolics in the construction.

The invention lies immediately in the search for the smallest bung diameter possible. In this case, the invention is aimed at proposing new solutions for taking back one or the other of these antics, or both.

For this purpose, the invention is designed to allow the implementation of alternative solutions, for the recovery of the frog barrel "alone": contact between the barrel drum and / or the barrel cover on the one hand, and on the other hand a range of the bung, or the barrel shaft according to the architecture of the bung; contacting, in one or more surfaces, the mainspring on the one hand, and on the other hand the barrel drum and / or the barrel lid.

In this embodiment with contact between the spring and one or more of the internal surfaces of the chamber in which is enclosed the spring (that this chamber is constituted by a drum and a lid, or by a drum and a ratchet, or by a drum and a bridge), several variants are feasible: the first inner turn of the spring, in contact with the receiving surface of the bung, is higher than the other turns; another turn, sufficiently far from the bung to not cooperate with a range of the bung, but to cooperate directly with an inner surface of the drum, or cover, or the like, is higher than the other turns; some turns are higher than the other turns; at least one turn higher than the others is reported on the spring; or, to provide a frost-limiting contact between the spring and an inner wall of the chamber, the drum and / or the cover comprises or comprise one or more protuberances, projections, threads or the like, on an inner face turned towards the spring. Here, a "surface" is a surface, preferably of revolution, protruding from a surface, for cooperating against a surface adjacent to another component to maintain these surfaces at a distance from each other when the catching up of games the mechanism, under the effect of gravity or acceleration due to a movement of the user pushes these components towards each other.

Regarding the recovery of the frog barrel complete with the blank in which is incorporated the accumulator mechanism, the invention proposes several variants: a contact between on the one hand a range of the bung or the barrel shaft (according to the constitution of the bung), and secondly a stone or a guide element that comprises a plate or a bridge of the draft; contact between on the one hand the barrel drum and / or the barrel lid, and on the other hand a stone, or similar guiding means, driven into a plate or a bridge, via one or a plurality of protuberances, projections, threads or the like provided or arranged on one side of the drum and / or the cover contact between on the one hand the barrel drum and / or the barrel lid, and on the other hand a stone, or similar guiding means, driven into a plate or a bridge, via one or several protuberances, projections, nets or the like, arranged or arranged on one side of the plate and / or the bridge.

The figures illustrate certain particular embodiments among the multiple combinations that can be made according to the invention.

This watch accumulator mechanism 1 comprises a barrel assembly comprising at least one mainspring 2 of barrel mounted between, at a first end 21 a barrel drum 3, and at a second end 22 a receiving surface 5 that has a barrel plug 4. This plug 4 is coaxial with the drum 3 about a pivot axis D. According to the invention, the maximum radius of the plug 4 with respect to the pivot axis D is less than nine times the maximum thickness of the spring 2 In particular, the illustrated embodiments make it possible to obtain a ratio close to five.

According to the invention this accumulator mechanism 1 comprises a plate 10 and a bridge 11, means for adjusting the longitudinal gap 6 between the barrel assembly, and the plate 10 or the bridge 11.

These adjustment means are: or else constituted by means for setting or limiting the stroke, with respect to the plate 10 or the bridge 11, of the drum 3 and / or of a lid 7 fixed on the drum 3 to form with it a chamber 32 enclosing the spring 2, or else constituted by pivotally guiding means, directly in the plate 10 and / or in the bridge 11, of the drum 3 and / or of such a cover 7 fixed on the drum 3 to form with it a chamber 32 enclosing the spring 2, or constituted by the combination of these means for setting or limiting the stroke and the pivoting guide means, in the direction of the pivot axis D, to limit the play between the barrel assembly and the plate 10 or bridge 11.

In the variant of FIG. 3, these adjustment means are constituted by means for setting or limiting stroke comprising a wedge washer 70 interposed between the plate 10 or the bridge 11, and the drum 3 or a lid 7 fixed on the drum 3 to form with it a chamber 32 enclosing the spring 2.

Preferably, this wedging washer 70 is guided by a bearing 44 that includes the bung 4, and more particularly is driven on this scope.

In a variant, the adjustment means are constituted by pivoting guide means directly in the plate 10 and / or in the bridge 11 of the drum 3 and a cover 7 fixed on the drum 3 to form with he a chamber 32 enclosing the spring 2.

In the variant of FIG. 6, the adjustment means are constituted by at least one projection 202 projecting from an outer surface 30 of the drum 3 facing the plate 10 or said bridge 11, and / or, as shown in FIG. 5, by at least one projection 102 projecting from an external surface of the plate 10 or the bridge 11 that includes the assembly 1, or belonging to a movement 100 or to a timepiece 1000 receiving this accumulator mechanism 1, and facing an outer surface 30 of the drum 3.

In the variant of FIG. 5, the adjustment means are constituted by at least one projection 207 projecting from an external surface 76 of a cover 7 fixed on the drum 3 to form with it a chamber 32 enclosing the spring 2, facing the plate 10 or at the bridge 11, and / or by at least one projection 107 projecting from an external surface of the plate 10 or the bridge 11 that the assembly 1 comprises and facing an external surface 76 of such a cover 7.

In the variant of FIG. 5, the adjustment means are completed by at least one projection 201, also visible in FIG. 4, protruding from an outer surface 121 of a ratchet 12 carried by the bung 4 facing the plate 10 or the bridge 11, and / or by at least one projection 101 projecting from an outer surface of the plate 10 or the bridge 11 that includes the assembly 1 and facing an outer surface 121 of the ratchet 12.

In a particular embodiment, the receiving surface 5 of the spring 2 is a surface of revolution relative to the pivot axis D.

In a particular variant, the spring 2 is fixed to the bung 4 by friction.

In a preferred embodiment, the spring 2 is welded or soldered to the bung 4 so as to form a subassembly bung-spring unbreakable monoblock.

Figs. 4 to 6 illustrate supports in the form of threads, respectively between a bridge 11 and the ratchet 12 in FIG. 4, and between on the one hand the bridge 11 carrying a net 102 and the drum 3, and on the other hand between the plate 10 and the cover 7 of the cylinder 1. This cover 7 carries a net 207 on fig. 5, which shows the plate 10 and the bridge 11 each carrying a thread, respectively 107 and 102, respectively cooperating with the cover 7 and the drum 3.

The support in the form of threads is formed between the drum 3 and a bridge 11, with a thread 202 on the drum 3 in FIG. 6.

FIG. 8 illustrates a two-piece stepped bung 4 4A and 4B, the latter 4B having a bearing surface 43 for guiding a bore 35 of the drum 3. The main part 4A is guided in a stone driven into the plate 10 at a level carried 182 at its lower end 87, guiding the cover 7 being on a bearing surface 44 of the flange 4A which cooperates with a bore 75 of the cover 7. The part 4B is guided by a bearing 181 in a stone driven into the bridge 11 towards its upper end 86. This figure illustrates a traditional attachment of the spring 2 on a hook 41.

FIG. 10 illustrates an inverted configuration with respect to that of FIG. 5, and this is the drum 3 of FIG. 10 which carries a net 202, intended to cooperate in support with a stone 302 driven into a bridge 11, 302 stone whose bore guides a scope 43 of the bung. In this particular variant, this same cylindrical bearing surface 43 extends to ensure the pivoting guidance of the drum 3.

The fact of wearing the net on the stone can control the friction torque between the net and the stone, and keep it at a very low value.

In this fig. 10 the frost between the bung and the assembled barrel assembly is given by the limitation of the support of the drum 3 and the cover 7 on the bearing surfaces 43A and 43B of the bung 4.

The play of the barrel assembly relative to the blank is defined by the axial play of the plug 4, which is limited by the thread 202 of the drum 3 facing the stone 302.

This variant of FIG. 10 is illustrated here with the bridge 11 interposed between the drum 3 and the ratchet 12.

FIG. 11 also shows a thread 202 of the drum 3 arranged to cooperate with a stone 302 driven into a bridge 11.

The bung 4 door, driven on one of its spans 44, a washer 70.

The fretting of the bung vis-à-vis the barrel assembly is limited by the movement of the washer 70 relative to a lower bearing surface 73 of the lid 7.

The luffing of the barrel vis-à-vis the blank is limited by the plug 4 with respect to the stone 702 of the plate 10 on the one hand, and by the thread 202 of the drum 3 relative to the bridge 11 on the other hand.

FIG. 12 also shows a thread 202 of the drum 3 arranged to cooperate with a stone 302 driven into a bridge 11, and a thread 207 of the cover 7 arranged to cooperate with a stone 702 driven into the plate 10.

In this fig. 12, axial play of the barrel alone is ensured by the spring 2 which has a projecting zone 23, here represented in the form of a first enlarged turn, cooperating directly, according to the position of the bung 4, with an inner surface 31 of the 3, or with an inner surface 71 of the lid 7. The barrel frog in the bridges is provided by the threads 202 or 207 on each side, outside the drum and lid.

FIG. 13 shows a thread 207 of the cover 7 arranged to cooperate with a stone 702 driven into the plate 10.

The bung is in two parts: the bung 4 itself carrier of the spring 2, fitted on a barrel shaft 18, with axial limitation by a bearing face 18A of the barrel shaft 18 and a face d antagonistic support 49 of the bung 4.

The bung 4, carrier of the inner end 22 of the spring 2, comprises a bore bore 411 cooperating with a bearing 84 of a barrel shaft 18.

The recovery of the frog barrel alone is provided by the spring 2, which has a projecting zone 23, here a flange reported or a turn sufficiently far from the axis so as to bear on the inner surface 31 of the drum 3 rather than a lower shoulder 189A of the barrel shaft.

While the frog of the barrel complete with the blank is provided on one side by an upper shoulder 189B of the barrel shaft 18 arranged to come into contact support with the stone 302 of the bridge 11, and on the other side by the contact of the thread 207 of the cover 7 on the stone 702 of the plate 10.

FIG. 14 also shows a thread 202 of the drum 3 arranged to cooperate with a stone 302 driven into a bridge 11, and a thread 207 of the cover 7 arranged to cooperate with a stone 702 driven into the plate 10.

The recovery of the complete barrel in the blanks is identical in FIG. 12 while the recovery of the frog of the barrel alone vis-à-vis roughing is done by contacting a scope of the plug 4, respectively 407 with the lid 7 or 403 with the drum 3.

This fig. 14 shows a ratchet 12 having a tapped thread on a thread that includes the bung 4.

FIG. 15 illustrates an advantageous variant with a bung 4 having a lower flange 40, which is arranged to abut by a bearing face 401 on an inner face 31 of the drum 3.

The fretting of the bung with respect to the barrel assembly is limited by the movement of the drum 3 and the cover 7 relative to the bearing faces 40A and 407 of the bung 4.

The play of the barrel assembly relative to the blank is framed by the contacts between the opposite bearing faces 49A and 49B of the plug 4, with the stones 702 of the plate 10 and 302 of the bridge 11 respectively.

The bung 4 is advantageously made of several coaxial parts to simplify its machining.

FIG. 16 illustrates a variant of the version of FIG. 14. In this version, the antics are repeated in the same way. But the guides are different because the pivoting of the drum 3 and the cover 7 are directly in the blank, respectively at the bridge 11 and the plate 10. This provision provides better control axial beat, because of the enlargement of the pivot diameter.

The invention also relates to a watch movement 100 comprising at least one such accumulator mechanism 1 for storing energy with an incorporated input, or else by a ratchet 12 mounted integral pivotally of the bung 4, or by a toothing drum 13 mounted pivotally integral with the drum 3, and an outlet respectively constituted by either a toothing drum 13 mounted pivotally integral with the drum 3, or by a ratchet 12 mounted pivotally integral with the bung 4 .

The invention also relates to a timepiece 1000 comprising at least one such watch movement 100 and / or at least one such accumulator mechanism 1 for energy storage with an incorporated entrance, or by a ratchet 12 mounted pivotally mounted on the bung 4, or by a toothing drum 13 mounted pivotally integral with the drum 3, and an outlet respectively formed, or by a toothing drum 13 mounted integral pivotally of the drum 3, or by a ratchet 12 mounted pivotally integral with the bung 4.

The invention provides the means for making a bung of very small diameter, and thus increase the storage capacity and the power reserve of a movement mechanism or ringing, or the like.

Control of lovemaking is important because it allows to limit the wear of the components, and increase the reliability of the mechanisms.
