Definitions
- the present invention relates to a clock with a dial, with one or more hands and with a clockwork with one or more concentric output shafts for moving the hands around a rotation axis of the pointer, the dial having a non-rotationally symmetrical surface when viewed in the direction of rotation of the hands, the Pointers are pivotally mounted on their inner end facing the axis of rotation of the pointer about a pivot axis running perpendicular to the axis of rotation of the pointer and perpendicular to the longitudinal axis of the pointer, and a control is provided with which the pointers can be pivoted so that they rotate with them Move a substantially constant distance above the dial surface.
- a clock of the type mentioned is known from DE-U 299 21 231.
- the hands always run at a constant, small distance over the dial when rotating over the non-rotationally symmetrical dial seen in the direction of rotation, but here one is considerably restricted with regard to the selection of the hands.
- the reason for this restriction is that the pointers are only pivoted transversely to their longitudinal direction during their rotation, which is the case with flat pointers, that is, relatively wide hands, as are generally known from large clocks in particular, lead to angular misalignments between the surface of the dial and the surface of the hands. These angular misalignments can reach such an extent that it is difficult to read the time; in addition, the visual appearance is significantly impaired by such incorrect angular positions.
- the known watch has narrow, rod-shaped hands, which preferably have a round cross section, so that such angular misalignments, as explained above, do not occur in a recognizable manner.
- these narrow, rod-shaped hands visually offer a very lean appearance, which is unsatisfactory for the designer of such a watch and which considerably limits the design options.
- the task is to create a clock of the type mentioned, in which greater freedom of movement in the geometric design of the hands is achieved and at the same time the representation and reading of the current time is guaranteed with good accuracy and clarity ,
- the hands are rotatably mounted on or near their inner end facing the axis of rotation of the pointer about a further axis of rotation running in the longitudinal direction of the pointer,
- the watch has such a storage and control of the hands, which ensure that the hands not only follow the course of the dial surface with a substantially constant distance but also also essentially parallel to the surface.
- This enables the use of conventional broader or flat hands which are conventional per se in conventional clocks, in particular large clocks.
- the rotation of the watch around its longitudinal axis creates a further astonishing optical effect for the viewer of the watch in order to maintain the parallelism between the surface of the hand and the face of the dial.
- clear and precise time display and reading is always guaranteed.
- the creative freedom for the geometric shape of the dial and the hands of the clock are expanded again, so that the creation of clocks with previously unrealizable appearances is now possible.
- the additional control is a rotary control which is arranged in the center of the watch and which is formed by a mechanical control curve for each hand, the course of the curve of which is designed in accordance with the course of the dial surface viewed in the direction of rotation of the hands,
- each mechanical control cam is arranged by a concentric to the associated output shaft tionary control disk or drum is formed with a control groove and - that in each control groove a control lever connected to the associated pointer is positively guided, through which the associated pointer can be rotated about its axis of rotation in the longitudinal direction of the pointer when it rotates in accordance with the course of the control groove.
- control for pivoting the pointers and the additional control for rotating the pointers about their axis of rotation running in the longitudinal direction of the pointer are combined to form a common control.
- the number of individual parts of the control system becomes smaller, which makes the manufacture and assembly of the control system and the clock overall easier.
- the common control is formed by a pointer, a calculated mechanical control curve, which is formed on or in the jacket of a stationary, conical or frustoconical control body arranged concentrically to the axis of rotation of the pointer, and in that Control cam each a control lever is positively guided by means of a cam roller pair with two cam rollers spaced apart from one another in the longitudinal direction of the cam, the distance between the control cam and the axis of rotation of the pointer being the pivoting position of the pointers and the gradient of the control curve between the two cam rollers of the cam roller pair the rotational position of the pointers around them
- the longitudinal axis of rotation of the pointer is determined.
- a control curve per pointer ensures both its appropriate pivoting and its appropriate rotation relative to the dial surface in order to ensure the desired constant spacing and the parallelism between the pointer and the dial surface in every rotating position of the hands.
- each conical or frustoconical control body is shaped such that it follows the rotating control curve at a constant distance.
- the distance is expediently such that the pointers run past the contour of their control bodies with a small but sufficient distance.
- the selected in the inventive clock controls can be realized in addition to the mechanical design in comparable ⁇ various alternative embodiments.
- Alternative designs of the control (s) can be implemented according to claims 6 to 8, for example with the aid of electrical servomotors or controlled electromagnets or position-controlled piston-cylinder units, in each case in connection with downstream mechanical actuators.
- the control signals required in these versions of the control can be supplied to the control, for example, as analog signals obtained by scanning or as digital signals retrieved from a data memory.
- the means for the pivotable and rotatable mounting of the hands, the control for pivoting them transversely to their longitudinal direction and the additional control for rotating the hands about their longitudinal axis are arranged on the visible side of the dial and that the hands extend radially outward from the center of the dial.
- the arrangement and the course of the hands in this embodiment of the watch are still relatively closely related to conventional watches, so that the particular visual appeal of such a watch lies in particular in the shape of the dial and in the movement of the hands relative to it.
- an alternative to the previously described embodiment of the watch provides that the means for the pivotable and rotatable mounting of the hands and the associated controls are arranged on the invisible back of the dial and that the hands from the center of the dial back to the outside and then. then extend around the radially outer edge of the dial ⁇ nd ' radially inwards in front of the dial front, preferably over less than half the dial diameter.
- the watch designed differently from conventional watches, but the arrangement and the course of the hands also differ significantly from conventional watches. For the viewer, only the portions of the pointers running on the outer circumference and on the visible side are visible, while the central area of the dial on the front can remain free of pointers and control means.
- the watch has several hands, they can be differentiated into, for example, hour, minute and second hands by the length and / or width of the visible hand areas or also by an additional or alternatively provided different coloring.
- the watch in this version also offers at least one additional benefit, which further increases the attractiveness of the watch.
- the dial of the clocks according to the invention can be designed in a geometrically diverse manner.
- a first preferred embodiment provides that the surface of the dial is formed from two partial surfaces which adjoin one another at their base at an angle ⁇ not equal to 180 °.
- a dial is created that has a kink in its surface.
- the two partial surfaces can be, for example, semicircular surfaces or other simple or complicated surfaces that together form the dial form.
- the clock according to the invention can be fitted, for example, in a form-fitting manner in the inner corner area between two room walls running at 90 ° to one another; If you choose an angle ⁇ of 270 °, you can, for example, attach the clock to an outside corner of the wall.
- the transitions between the partial surfaces can be rounded to a greater or lesser extent or can be designed as a polygon.
- the surface of the dial is formed from three partial surfaces with radially extending edges, the partial surfaces adjoining one another at their radially extending edges at an angle ⁇ not equal to 180 °.
- the three partial areas can e.g. consist of three equal-sized circular segment areas, which then together form the dial, which is composed of three dial partial areas running in different spatial levels. If an angle ⁇ of 90 ° is chosen between the respective partial surfaces of the dial, a dial results, which e.g. can be installed in a corner of a room in which two walls and a ceiling or floor area adjoin each other.
- angle ⁇ between the partial surfaces of the two previously explained designs of the watch it is preferably provided that it is between 90 ° and less than 180 ° or between more than 180 ° and 270 °.
- dials can be formed, which can be suitably arranged in inside corners or on outside corners of wall surfaces or pieces of furniture or other suitable surfaces.
- the transitions between the partial areas can also be rounded here.
- a third alternative design suggests that the surface of the dial, as viewed in the direction of the pointer rotation, be regular or irregularly wave-shaped or zigzag-shaped in a height-modulated manner.
- the watch has a modified, preferably suitable for radio control, movement and that the movement, the means for the pivotable and rotatable mounting of the hands and the control (s) are combined in an integrated clockwork gear unit.
- the watch has a conventional movement and that the means for the pivotable and rotatable Bearings of the hands and the controller (s) are combined in a secondary transmission which has input shafts which are in engagement with clockwork output shafts.
- the clock according to the invention can, as mentioned above, be designed as a wall clock; also a design as free standing or hanging clock is possible.
- the watch can be designed for indoor use or, if the watch parts are designed to be weatherproof or with a sealed housing, for use outside of buildings outdoors.
- the watch according to the invention can also be designed as a watch that can be worn on the body with a correspondingly small design. Because of the better recognizability of the optical effects achieved with the clock according to the invention when the hands are moved, however, a version as a large clock is preferred.
- FIG. 1 shows a watch in a first embodiment with two hands, viewed obliquely from the front
- FIG. 2 shows a control of one of the hands as part of the clock according to FIG. 1, in a top view
- Figure 3 shows the clock in a second embodiment, with three hands, in the upper half mainly in section and in the lower half in view, and
- FIG. 4 shows the clock from FIG. 3 in a view according to arrow IV in FIG. 3.
- the first exemplary embodiment of a watch 1 shown here has a dial 2, which is composed of three circular segment surfaces 21, 22, 23 of the same size.
- the circular segment surfaces 21, 22, 23 abut one another along their radial edges 21 ', 22', 23 'and each close an angle ⁇ of approximately 90 °, the transition from one circular segment surface 21, 22, 23 to the adjacent circular segment surface 21, 22, 23 being slightly rounded.
- the three circular segment surfaces 21, 22, 23 together form the dial surface 20, on which numerals 24 are attached to indicate the time in the form of Roman numerals I to XII.
- the transitions between the circular segment areas are expressed at 2:00, 6:00 and 10:00 a.m.
- the clock 1 can for example be positively placed in an upper corner of the room, the circular segment surface 21 parallel to a ceiling and the two circular segment surfaces 22, 23 parallel to a right and a left wall, the walls and the Include a ceiling of 90 ° with each other.
- the clock 1 according to FIG. 1 has two hands 31, 32, of which the pointer 31 is the minute hand and the pointer 32 is the hour hand.
- the pointers 31, 32 are elongated and tapered at their radially outer end. They are e.g. Sheet metal stampings that can still be color-treated.
- the pointers 31, 32 each terminate in a pin 58 which runs in the longitudinal direction of the pointer and which is rotatably mounted in a pivoting part 57 about a rotational axis 131, 132 extending in the longitudinal direction of the pointer.
- Clock 1 In the center of the. Clock 1 is a double swivel and rotation control 5, 6 arranged, on which the hands 31, 32 are movably mounted with their inner ends about two different axes, namely about a swivel axis 151 and a rotation axis 131.
- the pivot axis 151, 152 of each pointer 31, 32 runs perpendicular to the Pointer longitudinal direction and perpendicular to the pointer rotation axis 30; as a result, each pointer 31, 32 can be pivoted in the direction of the pivot arrow 51 ′′;
- the axes of rotation 131 of the rotary bearings formed by the pins 58 run in the longitudinal direction of the pointer.
- stationary control bodies with mechanical control cams which are invisibly concealed in FIG. 1 and which serve to move the pointers 31, 32 relative to the dial 2 about their respective swivel and rotation axes 151, 152, 131, 132 to be pivoted and rotated so that the pointers 31, 32 are always guided with a relatively small and in particular largely constant distance and at the same time parallel to the surface over the dial 2 which is non-rotationally symmetrical as seen in the direction of rotation of the pointer 31 '.
- the pointers 31, 32 must in the area of the radial edges 21 ', 22', 23 'of the circular segment surfaces 21, 22, 23 their most lowered, i.e.
- the pointers 31, 32 are simultaneously rotated about their axis of rotation 131 to an appropriate extent.
- the pointers 31, 32 are rotated as quickly as possible about their longitudinal axis; in the intermediate areas of the orbit of the pointers 31, 32 the rotation is correspondingly slower.
- the degree and speed of the rotation of the pointers about their longitudinal axis are determined by a corresponding curve profile of the control curves.
- a modified clockwork 4 (not visible here) is provided, which is replaced by a Cover 40 is covered.
- the clockwork 4 is designed together with the swivel and rotary control 5, 6 in the form of an integrated clockwork gear unit, which generates and transmits the time-dependent movement and the pivoting and rotation of the hands 31, 32 depending on the shape of the dial.
- the hands 31, 32 Although the dial 2 in the direction of rotation of the clock 31, the hands 31, 32, viewed as a non-rotationally symmetrical surface, the hands 31, 32 always run during their rotation at a largely constant and relatively small distance and parallel to the surface over the dial 2, so that despite the geometrically unusual and complicated shape of the dial 2, an accurate time display and reading is always guaranteed.
- FIG. 2 of the drawing shows the double pivoting and turning control 5, 6 arranged in the center of the clock 1 according to FIG. 1, now in a top view, partly in a broken away representation, only the minute hand 31 being shown here for clarity, which is shown approximately in FIG is in the three o'clock position.
- the swivel and rotary control 5, 6 is covered on its upper side facing the viewer in FIG. 2 by means of a continuous, rotating disk 50, which has the pointer 31 on its edge in the transverse swivel joint 51 with the swivel axis 51 'and in the axial Pivot bearing 58 with the axis of rotation 131, which coincides with the longitudinal direction of the pointer, carries pivotally and rotatably.
- the disk 50 is coupled to an output shaft 41 of the clockwork 4, which is invisible in the background, in the interior of the swivel and rotary control 5, 6 by means of coupling means (not shown), so that the disk 50 moved together with the minute hand 31 per hour by 360 ° in the direction of the hand 31 'around the axis of rotation of the hand.
- a fixed control disk 53 Arranged below the rotating disk 50 is a fixed control disk 53 as a stationary control body, which has an opening 54 in its center for the passage of the output shaft 41 or the aforementioned coupling means. Furthermore, the control disk 53 has a circumferential control groove 55 in its upper side facing the underside of the disk 50. In this control groove 55, a control lever 56 is positively guided at one end, the other end of the control lever 56 being rigidly connected to the inner end of the pivot part 57 carrying the pointer 31. As clearly shown in FIG. 2, the distance of the control groove 55 from the output shaft 41 varies in the circumferential direction. This means that the control lever 56, which is positively guided in the control groove 55, changes its orientation during the rotation of the pointer 31.
- control groove 55 By shaping the control groove 55 to match the shape of the dial 2, the desired effect can be achieved, namely guidance of the pointer 31 and, in the same way, of the pointer 32 (not shown in FIG. 2) in a relatively small and practically constant distance over the dial 2 regardless of the respective time and the associated position of the hands 31, 32 during their rotation.
- a fixed cylindrical control drum 63 is arranged as part of the additional rotary control 6, which also has an opening in its center for the passage of the output shaft 41 or the aforementioned coupling means.
- the control drum 63 also has a circumferential control groove 62 in its outer circumference.
- a second control lever 59 pointing in the circumferential direction of the control drum 63 is positively guided at one end, which is formed by a roller 60 mounted on a pin 61.
- the other end of the control lever 59 is rigidly connected to the pin 58 forming the radially inner end of the pointer 31, which is in turn rotatably mounted in the pivot part 57.
- the pivoting and turning control 5, 6 contains two separate control grooves 55, 62 for each pointer 31, 32 of the clock 1, so that each pointer 31, 32 is selected to an appropriate extent independently of the other pointer 32, 31. rend its rotation over the dial 2 so pivoted about its transverse axis and rotated about its longitudinal axis that the desired constant keeping of the distance and the parallelism of the surface is ensured with a small distance between the hands 31, 32 to the dial 2.
- the clock 1 can of course be supplemented by a second hand which is controlled in the same way.
- the clock 1 with three hands 31, 32, 33 is shown in FIG. 3 in the upper half above the pointer rotation axis 30, predominantly in section and in the lower half of FIG. 3 below the pointer rotation axis 30 in view.
- the dial 2 with its dial surface 20 is partially visible; the remaining part of the dial 2 is not shown in FIG. 3.
- a clockwork 4 On the far left in FIG. 3 is a clockwork 4, which is covered by a cover 40, so that it is not visible when looking at the watch, that is, from right to left according to FIG. 3.
- roller bearings 79 are provided for supporting the shafts 41 to 43.
- the clock 1 according to FIG. 3 has a combined pivoting and turning control 7 for the desired pivoting and rotation of the hands 31 to 33 in accordance with the course of the dial surface 20, which here corresponds to that of FIG matches.
- a carrier disk 71 for each of the pointers 31 to 33 is attached in a rotationally fixed manner. All three hands 31 to 33 are in the 3 o'clock position in FIG.
- a control body 73 is arranged between each two adjacent carrier disks 71 and to the right of the outer right carrier disk 71. These control bodies 73 are each fixed in position, that is to say cannot be rotated.
- Each control body 73 has the shape of a flat cone or truncated cone with a cone jacket 73 '.
- a control cam 75 in the form of a groove is fitted in each cone jacket, which runs around the entire control body 73 or its jacket 73 'and which has the shape of a curved curve.
- a control lever 76 which forms the base part of the pointer 31, 32, 33, is mounted in a swivel joint with a swivel axis 151, 152, 153 so as to be pivotable on the respective associated carrier disk 71.
- the pivot axes 151 to 153 run transversely to the axis of rotation of the pointer 30 and transversely to the longitudinal direction of the pointer.
- the conical jacket 73 ' can also be made slightly spherical or rounded, the crowning or rounding following approximately a radius about the associated pivot axis 151, 152, 153.
- each control lever 76 the remaining part of the associated pointer 31 to 33 is rotatably mounted in each control lever 76, in each case about an axis of rotation 131, 132, 133 which runs in the longitudinal direction of the respectively associated pointer 31, 32, 33.
- a cam roller carrier 78 with a pair of cam rollers 77 is in each case attached to the end of each pointer 31, 32, 33 protruding radially inward from the control lever 76.
- the cam rollers of each cam roller pair 77 lie within the associated control cam 75 and are guided therein.
- the cam rollers of the cam roller pair 77 each have a predetermined distance in the longitudinal direction of the control cam 75.
- each pointer 31 to 33 it rotates with both in and moved substantially constant distance as well as parallel to the surface 20 of the dial 2, even if it has a geometrically unusual and complicated shape, as shown, for example, the figure 1 of the drawing.
- this combined pivoting and rotation of the hands 31 to 33 is carried out by a common control 7 reached with the control bodies 73 and the other parts described above. This allows a particularly compact design with relatively few individual parts.
- FIG. 4 of the drawing shows the clock 1 from FIG. 3 in a front view according to the viewing direction IV in FIG. 3.
- the view falls on the outer surface 73 ′′ of the control element 73 on the far right, outer or upper.
- the pointer rotation axis 30 In the center of the control body 73 is the pointer rotation axis 30, which here runs perpendicular to the plane of the drawing.
- the circumferential, groove-shaped control cam 75 is visible in the jacket 73 'of the control body 73.
- This control curve 75 follows the outer contour 74 of the control body 73 at a short distance in order not to let the rotating pointer, here the associated pointer 33, collide with its control body 73 when it rotates around the pointer rotation axis 30.
- the pointer 33 is shown in FIG. 4, which is shown here again in the 12 o'clock position. In its radially outer area, the pointer 33 has a flat shape with a relatively large width. The pointer 33 merges into a cross-sectionally round shape towards its base. With this part, the pointer 33 lies within the control lever 76 and is rotatably mounted in the control lever 76 about the axis of rotation 133 extending in the longitudinal direction of the pointer. Behind the control lever 76 is the cam roller carrier 78 with the cam roller pair 77 guided in the cam 75.
- the pivot bearing with the pivot axis 153 then follows somewhat further towards the center, about which the pointer 33 can be pivoted in a plane perpendicular to the plane of the drawing in FIG.
- the dial 2 lying in the background in FIG. 4 with its dial surface 20 corresponds in its design to the dial 2 according to FIG. 1. Also in FIG. 4, the dial 2 thus has three circular segment surfaces 21, 22, 23, which together form the dial surface 20. In the 12 o'clock position of the pointer 33 shown in FIG. 4, the pointer 33 is located in the middle of the upper circular segment surface 21.
- the pair of cam rollers 77 takes place via the Cam roller carrier 78 and the control lever 76 a controlled, combined pivoting and rotation of the pointer 33 about the pivot axis 153 and the axis of rotation 133.
- the pivoting position of the pointer 33 and also the other pointers 31, 32, not shown here, is determined by the respective distance of the associated control cam 75 determined by the axis of rotation of the pointer 30. The closer the control cam 75 is to the axis of rotation 30, the further the free end of the pointer 33 in FIG.
- the pitch of rotation of the pointer 33 about its axis of rotation 133 is determined by the slope or direction of the cam 75 between the two cam rollers of the cam roller pair 77.
- the course of the control curve 75 is so explained that such a displacement of the pointer 33 about its axis of rotation 133 results that the pointer is guided in its flat outer part parallel to the dial surface 20.
- the greatest changes in the slope or direction of the control cam 75 are in the vicinity of the positions 2 o'clock, 6 o'clock and 10 o'clock, where the individual circular segment surfaces 21 to 23 of the dial surface 20 abut each other. In the areas in between, the control curve 75 runs flatter and with less change in its slope or direction, since in these areas the circular segment surfaces 21 to 23 represent flat areas.
- the controller 7 thus ensures with only one control cam 75 for each pointer 31 to 33 that the associated pointer 31 to 33 is guided over the dial surface 20 both at a substantially constant distance and parallel to the surface.
