EP2703913A2 - Timepiece to display a value of a time unit - Google Patents

Abstract

The clock (1) has a pointer, particularly an hour hand (4), driven by a clock unit, and a manually rotatable pointer, where the former pointer is rotated independently from the manually rotatable pointer. A time display of a time unit is performed during the overlapping of the pointers, while the latter pointer points towards the angular position of the current time of the observed time unit. A reasonable hour reading is not possible while the time points and angles of the overlap of the pointer are outside.

Description

The invention relates to a clock for displaying a value of a time unit.

background

The analogue time display on a clock is usually based on hour, minute and second hands. These hands are driven by a clockwork, which is mounted in a housing. Through the watch glass of the housing, the angular position of the hands can be recorded on a scale and the current time can be read.

In addition to the clock-driven clock hands such as hour and minute hands are also known from the prior art pointers that are not driven by the movement, see, for example, document CH 343 919 A , Such not driven by the clock hands can be manually adjusted by hand, without affecting the angular positions and rotational movements of the clock driven by the clock and serve, for example, to measure the duration of dives on diver's watches. In contrast, in the document DE 10 2010 020 466 A1 discloses a watch having a hand rotatable hand whose rotation affects the angular positions of the remaining hands such as hour and minute hands. In the document DE 10 2010 020 466 A1 a clock is displayed when a hand-rotatable pointer of the remaining hands meet.

As the designation of clock hands already makes clear, they must point in a clearly visible direction. This is necessary for a clear detection of the angular position of the hands on the clock scale for reading the time. In the design of the various elements of the display such as pointers, scales and numbers is therefore to be considered that the direction of the pointer is clearly visible. If clock hands do not point in a clearly visible direction or are obscured by other elements of the display so that the direction indicated is not clearly recognizable, the time can not be read or only with high inaccuracy. The requirement for clock hands to point in a clearly recognizable direction therefore limits the shape of the elements of the display.

Summary

The invention has for its object to provide a clock for displaying a value of a unit of time, in particular clock with analog time display, which makes it possible to produce clocks with time display in greater design variety. In particular, a possible free design of the hands should be provided.

This object is achieved by a clock according to claim 1. Embodiments are the subject of dependent claims.

There is provided a clock for displaying a value of a time unit, with a read-off element, wherein a rotation of the read-off element is manually controllable, and a time unit correspondingly rotating mold element, wherein the rotational movement of the mold element is independent of a manually caused rotation of the read-off element and wherein the Value of the unit of time is readable only when a coincidence of the two elements by the angular position of the meeting indicates the value of the unit of time.

It can be provided that the read-off element for reading the value of the time unit is manually rotated so that the read-off element and the form element meet. The read-off element may stand still when it comes into contact with the mold element for reading the value of the time unit. The read-off element and the form element can have the same axis of rotation. It can be provided that the meeting of read-off element and form element takes place exclusively in the angular position in which the read-off element and / or the form element point to the value of the time unit. There may be a scale corresponding to the time unit, wherein only at a meeting of the read-off element with the form element, the read-off element and / or the form element indicate the value of the time unit on the scale.

The meeting of the read-off element with a form element for reading the time can take place in different ways. Both elements may overlap partially or completely, one element may partially or completely frame the other element and at least one side or at least one end point of the one element may collide with at least one side or at least one endpoint of the other element. Likewise, the meeting of the read-off element with a form element for reading the time can be effected by a combination of the three variants mentioned above. The way in which the read-off element and the form element meet can be the same for all time-unit values that can be represented by the clock.

The display of a value of a further unit of time can be provided, wherein a further mold element rotates according to the further time unit and the value of the further time unit comparable to the interaction of read-off element and mold element is readable only when the further mold element meets the read-off element or another read-off element, in that the read-off element or the further read-off element and / or the further form element point to the value of the further time unit.

At least one element of the display may have a disc-shaped figure of any shape. At least one element of the display can have at least one line-shaped or flat marking or recess of any shape on a disk-shaped figure of any shape. The disc-shaped figure can rotate eccentrically. At least part of the shape, marking or recess of a read-off element may correspond to at least part of the shape, marking or recess of a molding element. The molding element may be at least partially obscured by another element of the display. The read-out element may have a shape, recess or mark towards the edge, which increases the reading accuracy.

The read-out element can rotate correspondingly to a second hand and a manual rotation of the read-off element can interrupt the rotation corresponding to a second hand for the duration of the manual rotation of the read-off element.

The elements of the display may consist of one or several solid materials. A form element can be driven by a clockwork, and the clock of the movement can be a quartz crystal or a balance. The elements of the display can be displayed on an electronically controllable display screen or projected onto a projection screen. The unit of time, whose value from the clock through the The clash of two items can be the hour, minute, or second.

Starting from the angular position in which the read-off element and the mold element meet to indicate the value of the time unit, the rotational movement of the mold element causes the mold element with the passage of time from the angular position in which the read-off element and the mold element for displaying the value of the Time Unit met, moved out, whereby the mold element is in a new angular position in which the mold element does not meet with the read-off element. Only after a complete revolution of the mold element or a manually generated rotation of the read-off element can the mold element meet again with the read-off element.

In one embodiment, a timepiece with an analogue time display is provided which has an analogue display, a form element which is rotatably mounted about an axis of rotation of the analogue display, a clockwork which is suitable, a clockwork driven and a time unit corresponding rotation of the mold element about the axis of rotation to drive, as well as having a read-off element, which is freely rotatably mounted freely rotatable about the axis of rotation or another axis of rotation, such that a manual rotation of the read-off element independently and decoupled from the forced by the clockwork rotation of the mold element is executed. Furthermore, markings are provided, which are formed with partial markings on the mold element and on the read-off element and which are at least partially visible at least in a reading position of read-off element and mold element relative to each other in the direction of the analog display. The reading position can be adjusted manually by manually rotating the read-off element, such that the partial markings on the read-off element are brought into a position assigned to the partial markings on the mold element. In the reading position, the read-off element displays a true or current analogue value for the time unit on the analog display, but not in other rotational positions of the form element and the read-off element relative to one another that differ from the read position.

In the reading position, the form element whose rotation of the unit of time is forced by the clockwork, and the manually rotated read-off a

Relative position (relative rotational position) arranged to each other, which is determined by the predetermined mutual assignment of the part marks on the form element and read-off element. The partial markings are designed in such a way that the reading position is assumed in exactly one relative rotary position or relative angular position of the shaped element and read-off element. In other relative positions of form element and read element to each other no true or current value for the time shown analogously is readable.

It can be provided that the markings have partial markings executed as picture elements on the read-off element and the shaped element. For example, it may be provided that any symbols such as dashes, circles, points, triangles or the like are used, which are to be arranged one above the other or in a predetermined manner relative to each other in the reading position. The assumption of the predetermined relative position is carried out by means of manual rotation of the read-off element.

The markings may have partial markings on the read-off element and the shaped element which are designed as shaped elements. Shaping elements are characterized by shape or contour sections, it being possible to provide that in the reading position they are partially or completely positively adjacent to one another in the viewing position in the viewing direction on the analogue display or are arranged lying against one another.

The markings can be arranged on the read-off element and / or on the mold element in the region of a section of transparent material, through which the partial markings on the other element, namely the mold element or the read-off element, at least partially visible in the reading position.

It can be provided that the markings on the read-off element and / or on the mold element have a recess which in the read position with an associated part mark on the other element, namely the mold element or the read-off element, in the direction of the analog display at least partially positive fit overlaps.

The read-off element and the form element can be arranged partially or completely superimposed in the reading position in the direction of the analog display. The mold element can be designed as a pointer.

A further form element and a further read-out element associated therewith can be provided for which a further read position is manually adjustable, comparable to the interaction of the form element and read element, in which a true analog value for a further time unit is displayed on the analog display by means of the further read element which is different from the time unit. The further form element and the further read-out element associated therewith have - similar to the design of the form element and read-off element - markings with corresponding part markings, which may be embodied in their concrete training equal to or different from the part marks on the form element and read-off element. For example, the time unit relates to the hour and the further unit of time to minutes. Including a second display can also be provided in a comparable way.

According to another embodiment, a clock is provided in which the angular positions of the clock hands are determined by a manual rotation of at least one additional mold element by the additional mold element is successively brought into line with the clock hands. Here, the additional mold element has a shape that points in a unique direction.

In one embodiment, a clock with a driven by a clockwork first pointer (form element) and a manually rotatable second pointer (read-off element) is provided, wherein the rotational movement of the first pointer is independent of a manually generated rotation of the second pointer, wherein a time display with respect Time unit only takes place when both hands meet by the second pointer points to the angular position of the current time of the time unit under consideration, while outside the time and angle of the meeting of the pointer meaningful time reading is not possible.

The first pointer (molding element) may have a shape that does not point in a clearly recognizable direction. The second pointer (read-out element) may have a shape that is in a clearly identifiable direction. A part of the second pointer may correspond to the shape or part of the shape of the first pointer. Both hands can have the same axis of rotation.

There may be another clock driven by the clock (another form element) may be provided, wherein the first pointer (mold element) rotates according to an hour display and the other hand is rotated according to a minute display from the movement. When the second pointer (read-out element) meets with another pointer for reading the time, a partial or complete superimposition of both hands can take place. When the second pointer meets with another pointer for reading the time, a partial or complete frame of the one pointer can take place by the other pointer. When the second pointer meets with another pointer for reading the time, a meeting of the sides of both hands can take place. The second hand can be driven by the movement of the rotational speed of a second hand accordingly. A manual rotation of the second pointer can interrupt this drive of the movement.

An embodiment of the clock has an hour hand (form element) and a minute hand (another form element) in addition to the read-off element. In this case, the current hour is displayed in a correspondence of the read-off element with the hour hand and the current minute when the read-out element coincides with the minute hand.

A correspondence between the read-off element and the hour or minute hand (form element and further form element) can be made on the basis of the complete or partial meeting of clock hand and read element. For example, the pages of the clock hand and the read element can meet. Likewise, parts of the clock can be covered by the read-off element or vice versa. A coincidence between the clock hand and the read-off element can also be achieved by filling a recess of the one element with a corresponding shape of the other element. Consequently, a correspondence of the read-off element with the hour hand or minute hand is more generally described in that the read-off element partially or completely simulates the shape of hour and minute hands.

When reading the time, the read-off element can be rotated clockwise or counterclockwise. Furthermore, the current time is read sequentially, so, for example, the hour and then the minute are read. In angular positions of the read-off element and the clock hands (form elements), in which none of the clock hands coincides with the read-off element, an exact or unambiguous reading of the time is not possible.

The proposed watch, in one possible embodiment, can be described as follows. The analogue display has time-unit markings arranged circumferentially. In the area of the display, a mold element (non-pointer element) is arranged, which performs a forced / driven rotational movement about an axis of rotation corresponding to the time unit. From the synopsis of the form element and time unit markings, the current / actual time is not or not exactly readable. On the display a read-off element (pointer element) is further arranged, which is mounted for rotation about the rotation axis or another rotation axis manually, wherein the manual rotation is independent and decoupled from the forced rotation of the mold element. From the synopsis of reading element and time unit markings, the time can be read exactly in a reading position. The readable time in the reading position corresponds to the current / actual time. In the reading position, partial markings are arranged on the shaped element on the one hand and on the read-off element on the other hand in an associated reading position. Only this relationship of the partial mark on the form element and the read-off element allows an accurate reading of the current / actual time. The combination of read-off element and time unit markings makes it possible to read the actual / current time, which is precisely not possible or not exactly possible from the synopsis of the form element and the time unit markings. The combination of form element and time unit marking gives the user either no or only with high inaccuracy interpretable indication of the actual / current time. For example, a time that is not accurately legible is present at the time unit minute with 60 time unit markings if the current / actual minute can only be read with an error of at least plus / minus one minute.

another technical realization of the clock.

In Fig. 1 a clock 1 is shown with a 12-hour scale 2 and a mold element 4. According to the 12-hour scale, the mold element 4 completes exactly one revolution around the axis of rotation 3 clockwise in 12 hours. Due to the rotation of the mold element 4 corresponding to an hour hand, it can also be called an hour hand. The hour hand 4 is shaped so that it is not possible to quantify the current angular position. It is not clear which direction the hour hand is pointing. Without a definition of the displayed direction of the hour hand, for example, in a user manual reading the current hour is thus not possible. Even if the indicated direction of the hour hand were known to the user of the clock, this could read the displayed direction only very inaccurate due to the shape of the hour hand.

As in Fig. 2 1, the clock 1 provides a read-out element 5, by means of which the rotational position of the hour hand can be read accurately. Since the arrow-like shape of the read-off element 5 intuitively reveals the indicated direction, it is therefore not necessary to look up it in a user manual.

In Fig. 2 the clock is 1 off Fig. 1 additionally shown with a read-off element 5. The read-off element 5 has a recess 7 which corresponds to the shape of the hour hand 4. Furthermore, the read-off element 5 has on the outside a shape 55 which points in a specific direction 6. In Fig. 2 is the read-off element 5 in the 12 o'clock position and thus points to the hour "12". The read-off element 5 is manually rotatable by the same rotation axis 3 as the hour hand 4. A manual rotation of the read-off element 5 takes place independently of the rotation of the hour hand 4. With a manual rotation of the read-off element 5, the hour hand 4 carries on its rotation predetermined by the movement without being influenced.

The current hour can be read when the read-off element 5 is rotated by hand so that it meets or matches the hour hand 4. A meeting of both elements 4 and 5 is in the embodiment in Fig. 2 then given when the hour hand 4, the recess 7 in the readout element 5 fills. Because the Recess in the read-off element 5 the hour hand 4 not completely framed, the current hour in Fig. 2 not be read.

In Fig. 3 the clock is 1 off Fig. 2 shown after a manual rotation of the read-off element 5. Here, the hour hand 4 now completely fills the recess 7 of the read-off element 5 and the read-off element 5 points in the direction 6 of the current hour. The current hour is thus 9 o'clock.

Between Fig. 2 and 3 For example, the read-out element 5 was manually rotated either 90 degrees counterclockwise or 270 degrees clockwise. In one embodiment, it is provided, for example, that the read-off element 5 is mechanically coupled to a rotatably mounted steady rest.

In Fig. 4 an embodiment of the clock 1 with scale 2, a mold element 4, a further mold element 8 and a read-off element 5 is shown. All three elements have the same axis of rotation 3. Using a 12 hour and 60 minute scale, the former 4 performs one full rotation every 12 hours and the other one performs a full rotation every 60 minutes. The mold element 4 can thus be called hour hand and the further mold element 8 can be called minute hand. The read-off element 5 points in the direction 6 of the hour "6" or the minute "30". However, since the read-off element 5 does not coincide with either the minute hand or the hour hand 4 and hour and minute hands are shaped so that they do not indicate a clear direction, in FIG. 4 not the time to be read.

In Fig. 5 is the embodiment of Fig. 4 displayed when reading the minute. The read-off element 5 coincides laterally with the minute hand 8 and thus points in the direction 6 of the current minute. Thus, the current minute is "0". Analogously shows Fig. 6 the embodiment Fig. 4 while reading the lesson. Here the pages of the hour hand 4 and the read-off element 5 meet. The read-off element 5 points in the direction 6 of the current hour, which is "9".

The three 4 to 6 thus represent snapshots of a clock at the time 9:00 clock. Here, the read-5 was within a few seconds manually by hand rotate to read the time so that the angle changes of the hour and minute hands due to the continuous time are so small that they are not visible.

In a further embodiment, the display of a second is provided. Since a second hand rotates noticeably faster than a minute or hour hand, it is possible to execute the second hand in the same shape as the hour or minute hands. When reading the time, the second hand is not distinguished in this case by another form, but by the much faster rotational speed of the other hands.

In Fig. 7 an embodiment of a clock 1 with scale 2 and a form element or hour hand 4 is shown. To illustrate the formation of the hour hand 4, the read-off element is not shown. The hour hand consists of five linear markings printed on a transparent disc. The hour hand rotates about the rotation axis 3.

In Fig. 8 is the embodiment of Fig. 7 depicted with read-off element 5. The read-off element 5 is similar to the hour hand 4 of five line-shaped markings on a transparent disc, but still has an additional annular mark 54 on the edge. Based on this annular marking, the current angular position of the read-off element 5 can be determined exactly. The read-off element 5 can be rotated by hand about the rotation axis 3. To read the current hour, the read-off element 5 must be rotated so that the linear markings of the hour hand 4 and the read-off element 5 together form a star. For this, the end points of the linear markings of the read-off element must hit the end points of the linear markings of the hour hand. If the line-shaped markings give a star, the annular mark 51 of the read-off element 5 points to the current hour.

In Fig. 9 is the embodiment of the clock 1 from the Fig. 7 and 8th to read the current hour. Here, the read-off element 5 was manually rotated so that the end points of the linear markings of the hour hand and the read-off element 5 meet and give a star. The annular marking 51 of the read-off element 5 points to the current hour, which is thus 2 o'clock. As the star in the Relative to the axis of rotation 3 is arranged eccentrically, meet the end points of the linear markers of the hour hand and the read-off element 5 only in a certain angular position on each other.

In Fig. 10 another embodiment of a clock 1 is shown. Below is the form element or the hour hand 4 is arranged, which consists of a small circular disc. This is followed by the further form element or the minute hand 8 consisting of a disk with a large circular hole 81. Above the minute hand 8 is the scale 2 followed by the read-off element 5. The read-off element 5 has the same shape as the minute hand with an additional recess 51 at the edge, as well as a ring 52 in the middle. The ring 52 of the read-off element has the same diameter as the minute hand. In the present embodiment, the read-off element 5 is printed on a transparent pane. Hour hand, minute hand and read-off element 5 have the same axis of rotation 3.

In the embodiment in Fig. 10 Due to the shape of the hour hand 4, the current hour can not be read or only with very high inaccuracy. Furthermore, the read-out element 5 partially hides the minute hand 8, as a result of which the current minute can likewise only be read with very little inaccuracy. The scale 2 is also partially hidden by the read-off element and visible only in the immediate vicinity of the recess 51. The scale can thus be used for an exact determination of the angular position of the read-off element.

In Fig. 11 is the embodiment of Fig. 10 to read the current minute. Here, the read-off element 5 was rotated so that the hole 53 of the read-out element coincides with the hole 81 of the minute hand 8. The minute hand is thus completely covered by the read-off element. In this position, the recess 51 of the read-off element points to the current minute, which is thus "0".

In Fig. 12 is the clock 1 from the embodiment of the Fig. 10 and 11 to read the hour. Starting from Fig. 11 For example, the read-out element 5 was rotated 60 degrees clockwise, so that the ring 52 coincides with the hour hand 4. In this common arrangement of the reading element and the hour hand shows the recess 51 of the reading element to the current hour, which is thus "2". Together with the in Fig. 11 The minute is the time of 2:00 o'clock.

In a further embodiment of the example of the 10 to 12 is the display of the time in another time zone provided. For this purpose, a further hour hand is used, which is arranged directly above the circular hour hand 4. The other hour hand has the same shape, size and eccentricity as the hour hand. The other hour hand is partially transparent so that the underlying hour hand 4 remains visible. Due to the coincidence of the shapes of both hour hand, their angular positions can be read with the ring 52 of the readout 5.

Fig. 13 shows an embodiment of the clock 1 with an hour hand 4, which is shaped like a conventional clock hand and thus corresponds to a radially extending from the center of the display line. The rotation axis 3 of the hour hand 4 is at the center of the display. As in Fig. 14 shown is located above the hour hand 4, a circular reading pointer 5 with center equal to the center of the display. The read-out pointer 5 can be rotated manually about the rotation axis 3 of the hour hand 4 or the center of the display. Furthermore, the read-out pointer consists of a non-transparent material and has four radially extending line-shaped recesses 56. Through the recesses 56, the underlying elements of the display are visible. As in Fig. 14 is shown, the hour hand is in angular positions in which the reading pointer does not match the hour hand, completely obscured by the reading pointer and the current hour can not be read.

In Fig. 15 is the reading position of the clock 1 off FIG. 14 displayed. Here, the recess 56 of the reading pointer 5 hits the hour hand 4, so that the hour hand 4 is visible through the recess 56 of the reading pointer 5. In the reading position, the hour hand points to the current hour. The use of a plurality of recesses 56 in the reading pointer 5 has the advantage that the reading pointer for reading the current hour must be rotated less far until the hour hand hits one of the recesses of the reading pointer.

A technical realization of the clock is in Fig. 16 shown. Here, a watch case 9 is used with rotatable bezel 10. The bezel is a gear 11 with the

Read-off element 5 coupled, so that upon rotation of the bezel, the read-off element is also rotated. The movement 12 drives an hour-4 and a minute hand 8 and is not mechanically coupled to the bezel or the read-off element 5. All three hands have the same axis of rotation 3 and are shown in the form of transparent discs to which any pointer shapes can be applied.

Another technical realization of the clock is in Fig. 17 shown. The watch case 9 has a housing glass 13 and includes a movement 12 with hour 4 and minute hands 8. A rotatably mounted bezel 10 is located above the housing 13 also with a glass glass 14 on the inside of the read-off element 5 is applied. The scale of the display can be applied to the housing glass 13. The use of two glasses 13, 14 on the clock hands 4, 8 has the advantage that the clockwork sealed with high water resistance whereas the bezel can be provided with a possible easy rotatable seal.

A technical effect and utility of the proposed clock as opposed to the clock from the document DE 10 2010 020 466 A1 is that the rotational speeds of the hands and the manual or automatic winding mechanism and the hand setting mechanism of conventional movements can be used without modifications to the realization of the created clock.

In a further embodiment, the read-off element 5 is coupled to the drive axis of the second of the movement, so that the read-off element 5 additionally serves as a second hand. When manually rotating the reading element to read the hour and minute, the second is adjusted so to speak. By means of a friction connection between the read-off element and the axis of the second movement, it is ensured that a manual rotation of the read-off element does not engage in the movement of the movement of the watch over the second axis. With a manual rotation of the read-off element, consequently, the transmission of the second drive of the movement to the read-off element is blocked. After a manual rotation of the read-out element, the second is therefore no longer displayed correctly. The coupling of the read-off element to the manual rotation can be done by means of a ratchet mechanism. Here, the read-off element can be rotated manually only counterclockwise, during the second drive of the movement, the read-off element clockwise drives. Alternatively, the bezel can be connected to the read-off element by pressing down the steady rest, wherein the toothing of the steady rest is coupled to the toothing of the read-off element only during the pressing down.

For that in the Fig. 16 and 17 Clockwork shown can be used both a quartz movement with battery and a mechanical movement with manual winding or automatic lift.

In a quartz movement which has a separate stepper motor for each clock hand, the rotation of the read-off element can be controlled by manual operation of pushers or crowns on the watch case and then performed by one of the stepper motors of the movement. Since the stepper motors of the movement can be controlled independently of each other, the thus indirectly generated manual rotation of the read-off element does not affect the rotational movement of hour and minute hands. Similarly, the display of the clock may be equipped with a touch-sensitive viewing window as known from touchscreens. Here, the touch of the viewing window can then be implemented by one of the stepper motors of the movement in a rotation of the read-off element.

The use of a separately controllable stepper motor for carrying out the manually controlled rotation of the read-off element makes it possible to use the read-off element as a second hand without losing the display of the current second after manually controlled rotation of the read-off element. This is due to the fact that the electronics of the movement can understand the position of the reading element relative to the current second. After the manually controlled rotation of the read-off element, the movement can thus rotate the read-off element to the current second and continue the display of the current second.

The watch can be both mechanically and in the Fig. 16 and 17 described can be realized, as well as an animation displayed on a screen or projected by a projector on a projection screen. When displaying the clock on a screen, any input device can be used for manual rotation of the read-off element such as the keys of a keyboard or a mouse, the scroll wheel of a mouse, a stylus or finger on a touch screen or a trackpad or trackball.

The features disclosed in the above description, the claims and the drawing may be important both individually and in any combination for the realization of the various embodiments.
