Definitions

  • the present invention relates to a clock comprising a machine, a cover that provides support for said machine, and a carriage surrounding said machine.
  • Wristwatches with an outer crown attached to a seatpost that are mechanically actuated on the hands of the watch are known in the state of the art to facilitate their setting time.
  • This time setting system is inconvenient because the seatpost goes through the entire clock machine and strongly conditions its design.
  • the post of the conventional time setting system limits, for example, the shape of the clock; For example, conventional automatic watches are difficult to be extra-flat, since the oscillating mass has to be above the clock machine. It also limits the aesthetic presentation that the watch can adopt; For example, in a clock, transparent the seat post breaks the harmony of the visible elements.
  • the seatpost limits the technical possibilities of the clock machine, since on the one hand it has to pass through said machine, and on the other hand it is accompanied by a mechanism integrated in the machine that acts on the hands of the clock and that reduces space in said machine.
  • Swiss Patent No. 662235 presents a wristwatch in which the winding and setting crown covers the periphery of the watch, surrounding the dial. This invention aims to provide a simpler mechanism than the traditional one for setting the clock, but in reality it does not eliminate the time setting, it only changes it. In addition, it is necessary to look closely at the position in which the crown is left after each time setting operation, since left in another position would cause the clock movement to stop. It is clear that This condition constitutes a serious inconvenience of this system.
  • An object of the present invention is to provide a clock that does not need a seatpost for setting up time and is more versatile and simpler than known watches.
  • the "mechanism” of the clock is called the set of mechanisms that cooperate to propel the clock hands, constituting a unit block (in this memory the machine is considered a “black box", although, naturally, the clock hands , which are driven by the machine, in operation have relative rotation movement with respect to it).
  • the radial envelope of the watch is called “carriage”; said carriage does not include the "cover” of the watch, which constitutes the base of the machine.
  • the dial marked on which the time is read based on the angular position of the clock hands is called the "dial" of the watch.
  • the machine is integral with the watch cover and the assembly formed by said cover and the machine is rotatably mounted with respect to the carriage, so that at least one clockwise can be set on time by rotating the assembly formed by the lid and the machine, with respect to the carriage, in a first direction of rotation.
  • any angular position with respect to said carriage can be obtained for at least one clockwise.
  • the machine can be placed in any position and the clock can take any form.
  • the watch comprises locking means to block with respect to the carriage at least one watch hand when the assembly formed by the cover and the machine is rotated, with respect to the carriage, in a second direction of rotation opposite to said first direction of rotation. That is to say, this arrangement makes it possible to set a needle by turning the machine in one direction, and to set the other needle in time, without moving the previous one, by turning the machine in the opposite direction.
  • said locking means comprise a ratchet mechanism interposed between the transmission of movement to the hour hand and the needle itself.
  • said ratchet mechanism comprises a ratchet wheel to which the hour hand is integral, and to which the proper rotation is imparted by friction during normal operation of the watch, and at least one catch intended to engage with said ratchet wheel to block its rotation in said second direction of rotation.
  • the latch slides on the ratchet wheel, but when you try to turn the machine in the second direction of rotation, the latch locks the ratchet wheel and the hour hand remains motionless with respect to the carriage, and to continue rotating the machine, and with it the minute hand, in said second direction of rotation, the friction between the ratchet wheel and the rotation transmission mechanism to the hour hand must be overcome.
  • the ratchet mechanism comprises two fasteners, each of which is crimped to one side of the ratchet wheel, said fasteners being fixed to a support plate that is stationary with respect to the carriage.
  • the lid comprises a crown that protrudes radially with respect to the carriage.
  • the cover comprises a cylindrical part and between said cylindrical part and the carriage a sealing gasket is provided that provides a machine-tight seal.
  • This joint also provides friction between the cover and the carriage, with sufficient force so that the cover cannot inadvertently rotate with respect to the carriage.
  • the cylindrical part of the lid is provided with a perimeter groove that can receive a plurality of screws, which pass through the carriage and serve to fix it axially to said machine, although they do not prevent the rotation of said carriage around the machine .
  • a bearing bearing of said machine is arranged between the machine and the cylindrical part of the lid. This is a very convenient way to support the machine for those stages of the clock operation in which the machine rotates with respect to the lid.
  • Figure 1 is a schematic elevation view of one embodiment
  • Figure 2 is a schematic of a mechanism of a conventional clock
  • Figure 3 is analogous to Figure 2 and illustrates a detail of an embodiment of the invention
  • Figure 4 is like Figure 3 but with shaders that functionally group related elements
  • Figure 5 is a plan view of a detail of Figure 3. Description of preferred embodiments
  • An embodiment of the invention is applied to a watch provided with a single needle, which rotates one turn in twelve hours and indicates the time on a dial marked for this purpose in an appropriate manner.
  • the machine 1 of the watch is integral with a cover 2 that constitutes the base thereof.
  • the embodiment comprises a carriage 3 that surrounds the machine 1 and can rotate around it, or vice versa.
  • a transparent glass 4 for viewing the time, indicated by the position of a needle 5 on a sphere 6, is attached to the carriage 3, as is the sphere 6.
  • the rotation of the needle 5 is given only by the internal mechanisms of the machine 1.
  • the cover 2 comprises a cylindrical part 1 provided with a perimeter groove 7 that can receive screws 8, usually in number of four, that cross the carriage 3 and serve to fix it axially to the cover 2; that is, said screws do not prevent the rotation of the carriage around the cover but do not allow a significant axial movement between these two elements.
  • the watch also comprises a gasket 9 that interposes between said cylindrical part 21 and the carriage 3 and provides a tight seal between them. To set this clock, it is sufficient to turn a crown 22, provided on the cover 2, which carries the machine 1 and the needle 5, until the needle 5 is on the desired position of the plate 6, which has remained motionless.
  • Another embodiment of the invention consists of a clock analogous to that of the previous embodiment but to which other elements have been added, such as a minute hand.
  • the laying procedure In time it is done in two stages, one for each needle. In the first stage the hour hand is set in time, in a manner analogous to that described for the previous embodiment, and in the second stage the minute hand is set, causing, for example, a ratchet mechanism to be described later. .
  • a conventional clock comprises a wheel 11, called “chaussée”, which is attached to a cylinder 12 that encapsulates a drive shaft 10.
  • the cylinder 12, and with it the chaussée 11, rotates together with the shaft 10 by virtue of friction Between both.
  • the chaussée 11 meshes with a wheel 14 to which a pinion 15 is attached, which, in turn, meshes with a time wheel 16 that is coaxial to the cylinder 12 and can rotate thereon by virtue of a barrel 17.
  • the minute hand 20 is fixed to the cylinder 10 and rotates accompanying its rotation.
  • the hour hand 25 is integral to the time wheel 16, the tooth relationships between the different wheels and pinions being precise so that the ratio between the rotation of both needles is correct.
  • the typical elements of a conventional clock represented in Figure 2 are known as known.
  • a ratchet wheel 30 is mounted which engages with a fastener 32 fixedly mounted on a support plate 36, which is fixed to the carriage 3.
  • the fastener 32 is provided with two hooks 33, one on each side of the ratchet wheel 30, which provide the crimp of the fastener with the wheel of ratchet.
  • Figure 5 more clearly depicts the ratchet mechanism.
  • the hour hand 25 is now integral with the ratchet wheel 30, and this is frictionally connected to the time wheel 16.
  • the clock of this embodiment operates like a conventional clock: the minute hand 20 rotates with the cylinder 12 and the hour hand 25 rotates together with the ratchet wheel 30 in the direction of the arrow
  • the sphere 6 and the plate 36, the fastener 32 are integral with each other, if the slight oscillation of the hooks 33, and the carriage 3, is disregarded and on the other hand, the hour hand 25 and the ratchet wheel 30 are also integral with each other, and the wheel 30 is frictionally connected to the time wheel 16, but this friction can be overcome if sufficient torque is applied.
  • the first stage of the time setting procedure is analogous to that described for the first embodiment, referring to Figure 1: the hour hand 25 is placed in the correct position with respect to the sphere 6 by turning the crown 22 an angle appropriate, but now this turn must be carried out in a defined direction, that of arrow A of figure 5.
  • the crown 22 is rotated in the opposite direction, that of arrow B of figure 5, with which at least one of the hooks 33 engages with the wheel 30 and the hour hand 25 remains still with respect to the sphere.
  • friction between the ratchet wheel 30 and the hour wheel 16 must be overcome.
  • the minute hand 20, accompanying the crown 22 and the rest of the machine 1 is rotatably rotated on the sphere 6 to the desired position, without the hour hand 25 moving from the position obtained in the first stage.
  • each of the elements that are integral with each other in the second stage described in the previous paragraph are grouped with the same shading. In this way two blocks with relative rotation movement between them are represented.
  • the invention provides a time setting system for a clock that eliminates the seat post and its associated mechanism, with the consequent saving of parts and space in the clock machine, and that only adds a simple ratchet mechanism, or similar, that does not condition the different aspects of the clock design at all.
  • the expression "the machine is integral to the cover” should be understood as limited to the time setting procedure, since during normal operation the clock could be the tree 10, or an element integral with it, the element that was integral with the cover 2, but as, in this case, in the setting of time said tree 10 and the machine 1 would be solidary, also in this circumstance would be the machine 1 and the cover 2.
  • a bearing (not shown) supporting the machine can be arranged between the two elements. In the absence of a seat post, said bearing can be advantageously arranged in an orbital position between the machine 1 and the cylindrical part 21 of the cover 2. In this way the machine is much better supported than if it is supported on a bearing that supports the shaft 10 (or equivalent element).

Abstract

L'invention concerne une montre qui comprend une machine, un fond qui fournit un appui à ladite machine et une carrure qui entoure ladite machine. Pendant l'étape de mise à l'heure, la machine est solidaire du fond de la montre et l'ensemble formé par la machine et le fond est monté rotatif par rapport à la carrure, de sorte qu'on peut mettre à l'heure au moins une aiguille de la montre en faisant tourner ledit ensemble dans un premier sens de rotation, par rapport à la carrure. La montre comprend des moyens servant à bloquer au moins une aiguille de la montre par rapport à la carrure quand ledit ensemble tourne, par rapport à la carrure, dans un second sens de rotation contraire au premier sens de rotation. Cette disposition permet de mettre une aiguille à l'heure en faisant tourner la machine dans un sens, et de mettre l'autre l'aiguille à l'heure, sans déplacer la première aiguille, en faisant tourner la machine dans le sens contraire.
