This application claims priority to European Patent Application No. 19197380.9 filed on Sep. 13, 2019, the entire disclosure of which is hereby incorporated herein by reference.
The technical field of the present invention is that of horology, and more precisely that of display mechanisms.
Display mechanisms are known from the prior art which have movements included in a plane and/or along an axis of freedom, which results in a restriction in the information provided to the user.
Indeed apart from an indication of the phase of the moon, the date and/or time, among others, no other indication or information can be provided simultaneously by the indicator to the user, in this case by the hand. In other words, the indicator cannot give two pieces of information at the same time.
The present invention proposes to fully or partially overcome these drawbacks via a display mechanism, in particular for a watch, and preferably of a watch, said display mechanism comprising at least:
Through this arrangement, the indicator can rotate about two separate axes of said dial, of the second hand, the minute hand or the hour hand.
In other words, said at least one first drive member is respectively integral with said dial, a second hand, a minute hand or an hour hand.
Through this arrangement, when the hand is movable about the first axis, the rotary element above the dial and in particular the scale, the second hand, the minute hand or the hour hand is in rotation about the second axis.
According to one embodiment, said first part is a barrel and/or said second part is the second axis of rotation and extends longitudinally along said at least one indicator member.
Through this arrangement, the hand is movable about the first axis via a barrel, and/or said second part supports the rotary element.
According to one embodiment, said at least one drive member assembly is at least one gear assembly comprising at least one first gear member and at least one second gear member, at least one micro-bearing assembly comprising at least one first micro-bearing and at least one second micro-bearing, and/or at least one bearing assembly comprising at least one first bearing and at least one second bearing.
According to one embodiment, said at least one rotary element is a counterweight of said at least one indicator member, a counterweight of a second hand, a counterweight of a minute hand or a counterweight of an hour hand and wherein said at least one indicator member is a body of a second hand, a body of a minute hand or a body of an hour hand.
Through this arrangement the counterweight of the indicator member can rotate about two separate axes.
According to one embodiment, said at least one indicator member is a second hand, a minute hand or an hour hand.
According to one embodiment, said second axis of rotation is coplanar with said dial and said first axis of rotation is in a different plane from said second axis of rotation.
According to one embodiment, said second axis of rotation is perpendicular to said first axis of rotation.
According to one embodiment, said at least one drive member assembly comprises a universal joint and at least one third drive member; said at least one third drive member being arranged at the end of said rotary element so as to drive said second hand, said minute hand or said hour hand about the first axis of rotation.
The embodiments and the variants mentioned above can be taken in isolation or in any possible technical combination.
The present invention will be clearly understood and its advantages will also emerge in light of the following description, given by way of non-limiting example only and with reference to the attached figures, in which identical reference signs correspond to structurally and/or functionally identical or similar elements.
The invention will be described below in more detail using the attached drawings, given by way of example and in no way limiting, in which:
The present invention, illustrated in
As can be seen in
The indicator member 110 may be mounted to rotate about a first axis of rotation 101 via a first part 103 which can act as a barrel 103, according to the embodiments, as can be seen in
This first part 103, or this barrel, moves with respect to a scale and preferably with respect to a dial 105 on which can be represented, for example, a scale representing the phases of the moon, a date and/or a time, in other words a scale representing the hours, minutes, seconds or any smaller graduations of a second such as a hundredth or other divisions of a second. Furthermore, this scale can represent the power reserve, tachometer, day of the week, month of the year, sign of the zodiac, temperature, pressure, altitude, depth, weather forecast, time zone or any other indication relevant to the user.
The indicator member 110 can also be rotatable about a second axis of rotation 102. This second axis of rotation 102 can be intersecting and/or perpendicular with the first axis of rotation 101, and, according to one embodiment, this second axis of rotation 102 can be coplanar with the scale, i.e. the dial 105, and the first axis of rotation 101 can be in a different plane to that of the second axis of rotation 102.
This second axis of rotation 102 extends longitudinally along the indicator member 110 and can be materialised by a second part 104 which extends longitudinally along the indicator member 110. The indicator member 110 can also be composed of a rotary element 111 which can be mounted to rotate about the second axis of rotation 102 via the second part 104.
As mentioned above, the display mechanism can also comprise a drive member assembly 120. This drive assembly comprises a first drive member 121 and a second drive member 122, as can be seen in
The second drive member 122 can be arranged on and/or in said at least one rotary element 111, and can be driven by the first drive member 121. The latter, in other words the first drive member 121, can be configured to cooperate with the second drive member 122 in such a way as to drive the rotary element 111 in a rotary movement about the second axis of rotation 102.
Indeed, the view of the mechanism in
The speed of the rotary element 111 about the second axis of rotation 102 can thus be determined by the location of the first drive member 121 and the second drive member 122 on the one hand, and on the other hand by the ratio, for example gearing, between the first drive member 121 and the second drive member 122. For example, the first drive member 121 can be integral with the scale, as mentioned above, of the dial 105, the second hand 106, the minute hand 107 or the hour hand 108 and/or the second drive member 122 can be integral with the hour hand 108, the minute hand 107 or the second hand 106, depending on whether the indicator member 110 is the second hand 106, the minute hand 107 or the hour hand 108.
Furthermore, depending on where the rotary element can be placed, a counterweight 109 may be necessary in order to counterbalance the imbalance generated by the weight of the second hand 106, the minute hand 107 or the hour hand 108 when the indicator member 110 is a second hand 106, a minute hand 107 or an hour hand 108 respectively.
According to one embodiment, the rotary element can be placed on the counter weight 109 of the second hand 106, of the minute hand 107 or of the hour and 108. Consequently, the counterweight 109 of the hand can be rotatable about the first axis of rotation 101 and about the second axis of rotation 102.
The drive member assembly 120, mentioned above, can be in the form of a gear assembly comprising a first gear member 121 and a second gear member 122, a micro-bearing assembly comprising a first micro-bearing and a second micro-bearing, and/or a bearing assembly comprising a first bearing and a second bearing. In certain embodiments, the drive member assembly 120 can be a universal joint, as illustrated in
In this case, contrary to the preceding paragraph, it is the first drive member 121 which is rotatable about the first axis of rotation 101 rather than the indicator member 110. Indeed, when the first part 103 of the universal joint turns about the first axis of rotation 101, the second part 104, in other words the rotary element 111, turns about the second axis of rotation 102 without being in rotation about the first axis of rotation 101.
The drive member assembly can also comprise, in this embodiment, at least a third drive member 123, which can be arranged at the end of the rotary element 110 for example, as can be seen in
In other words, the rotary element 110 only moves about the second axis of rotation 102. If it is desired to have an additional movement, it may be necessary to add at least a third drive member 123, so that when the first drive 121 is rotatable about the first axis of rotation 101, the second drive member 122, and by extension the rotary element 111 according to one embodiment, is in rotation about the second axis of rotation 102, and the third drive member 123 rotates the rotary element 111 about the first axis of rotation 101. Hence, the rotary element 111 may comprise a second piece of information which will be gradually revealed as the indicator member 110 turns about the first axis of rotation 101 and indicates a first piece of information.
