Definitions
- the invention relates to a watch with a rotatably mounted housing, with at least one pointer, the pointer being rigidly connected to the housing or formed by part of the housing, and with a clockwork.
- Such a watch is already known from the registered documents of utility model 89 08 646.
- This watch comprises a transparent housing in the form of a circular disc, which is mounted vertically on a base.
- the elements required to drive the pointers precisely are accommodated in the base.
- the minute hand is printed on the inside wall of the housing. To move the minute hand, the entire housing is rotated with the aid of the drive arranged in the base, the minute hand moving around the central axis of the housing.
- a peg is arranged in the central axis in the interior of the housing and starting from the housing wall.
- a dial is rotatably mounted on this pin. The weight distribution of the dial is chosen such that the dial always aligns itself independently of the position of the housing with respect to the vertical.
- a further transparent disk is also mounted on the journal, on which the hour hand is printed and which is driven accordingly.
- a special optical effect is to be achieved with the known watch, but the fact that one of the hands, namely the minute hand, is rigidly connected to the housing and the entire housing rotates to move this hand, is not exploited .
- the invention is based on the object of specifying a clock of the type in question, which is as simple as possible and while maintaining the classic pointer positions
- REPLACEMENT LEAF enables a time display with respect to the vertical forming the 12 o'clock / 6 o'clock position and thereby achieves a special optical effect.
- the watch according to the invention achieves the above object by the features of patent claim 1.
- the watch mentioned at the outset is designed in such a way that the housing is rotatably supported on a bearing axis so that the watch movement is parallel and offset to Drive axis arranged pointer drives, with which the pointer is operatively connected, so that the housing rotates at the speed corresponding to its pointer function around the bearing axis, and that the pointer position with respect to the 12 o'clock / 6 o'clock Position-forming vertical can be read.
- the rotation of the pointer which is formed by part of the housing, can be particularly emphasized if the housing is rotatably mounted on a bearing axis. This gives the impression of a free-floating pointer. It has also been recognized that the pointer formed by part of the housing can also be driven by driving the pointer axis.
- a particularly advantageous realization of the pointer drive consists in designing the watch structure so that the position of its center of gravity can be changed.
- the bearing axis is then guided through the housing such that the center of gravity of the entire watch structure is always preferably slightly below the bearing axis due to the rotation of the housing.
- the housing rotates around the bearing axis due to a shift in the center of gravity. The smaller the distance between the center of gravity and the bearing axis, the lower the torque exerted by the clockwork on the pointer, which is the movement of the pointer
- the drive of the pointer formed by part of the housing can advantageously be formed by a drive mass that can be moved against the housing and by the clockwork, with which the position of the center of gravity can be specifically changed.
- the drive mass is formed by the clockwork itself, which in this case is rotatably mounted with respect to the housing.
- the clockwork serving as the drive mass is also provided with an additional mass which ensures that the rotatably mounted clockwork always aligns reliably according to the force of gravity, the focus of the entire watch structure changing in a targeted manner.
- the clock according to the invention is also particularly advantageous since it always sets itself, i.e. the pointer formed by a housing part aligns itself according to the time of day, even if it is brought out of its position by external force and rotated about the bearing axis.
- the center of gravity of the entire watch structure is at any time in a defined position with respect to the housing, which is then always correctly aligned due to gravity.
- the special visual impression of the clock according to the invention is further emphasized by the fact that at least one further pointer is provided which is operatively connected to the pointer axis and which rotates about the pointer axis, which is arranged parallel and offset to the bearing axis.
- the special optical effect of the clock according to the invention can also be achieved by means of a number mounted on the pointer axis with play.
- REPLACEMENT SHEET Ferblatt be reinforced, which is ballasted so that it aligns itself automatically due to gravity.
- Such a dial then moves with the rotation of the housing around the bearing axis, the 12 o'clock / 6 o'clock axis of the dial always remaining aligned vertically.
- the ballasting of the dial can be achieved in a particularly simple manner by arranging an additional weight in the 6 o'clock position.
- Another advantageous possibility of ballasting the dial is that the dial is firmly connected to the clockwork, which is rotatably mounted with respect to the housing and has such an asymmetrical weight distribution that it aligns itself automatically due to gravity.
- the pointer rotating about the axis of the pointer can be arranged in front of the housing or the pointer formed by part of the housing.
- the dial can also be arranged in front of the housing.
- the pointer rotating about the pointer axis can now either be placed in front of the dial or arranged between the dial and the housing.
- special optical effects can be achieved by forming the individual parts, for example the dial, from transparent material such as, for example, plexiglass.
- the relative movement of the housing rotating as a pointer around the bearing axis and of the pointer rotating around the pointer axis is particularly noticeable if the housing is designed asymmetrically with respect to the bearing axis. This can be achieved by appropriate shaping or by markings or color effects.
- the watch structure is at least partially encapsulated by the housing.
- the housing also serves to protect against external influences.
- Fig. 1 shows a front view of an embodiment of a watch according to the invention
- FIG. 2 shows the object from FIG. 1, enlarged and schematic, in section through the area of the pointer axis.
- a clock 1 is shown with a housing 2 which is suspended rotatably mounted about a bearing axis 3.
- the housing 2 has an asymmetrical shape with respect to the bearing axis 3 and forms the hour hand of the clock 1.
- a minute hand 4 is operatively connected to a pointer axis 5 which is arranged parallel and offset to the bearing axis 3.
- a dial 6 is also rotatably mounted on the pointer axis and is ballasted such that it is always aligned with respect to the vertical forming the 12 o'clock / 6 o'clock position against the rotation of the housing 2 about the bearing axis 3. The dial 6 is therefore always oriented with respect to the vertical regardless of the position of the housing 2.
- the clock 1 shown in FIG. 1 shows 3 o'clock by the housing 2 hori-
- REPLACEMENT LEAF is aligned zontally to the right and the minute hand 4 points vertically upwards.
- FIG. 2 shows a section through a clock according to the invention in the area of the pointer axis 5.
- the hour hand forms a part of the housing 2 which is firmly connected to the rest of the housing 2 and which is connected by a rear cover 7 to a front pane 8 and possibly a transparent pane 9 is formed.
- a clockwork 10 drives the pointer axis 5, which is firmly connected to the housing 2 and thus to the hour hand via drivers 11 and the transparent disk 9.
- the housing 2 with the hour hand accordingly rotates relative to the clockwork 10.
- the mass distribution of the clockwork 10 is advantageously asymmetrical with respect to the pointer axis 5, so that the position of the clockwork 10 is always aligned with respect to the vertical due to the force of gravity.
- a dial 6 is firmly connected to the clockwork 10 via a fastening screw 12, so that the dial 6 is always “automatically” aligned due to gravity.
- the hour hand 2 is rotatable about the fastening screw 12 via spacer rings 13, i.e. rotatable with respect to the clockwork 10 and the dial 6.
- the minute hand 4 is also operatively connected to the pointer axis 5 via a reduction gear, not shown in FIG. 2.
- a second hand 14 is also provided in the clock shown in FIG. 2.
- the clockwork 10 can be both a mechanically driven and a battery-driven or solar-powered clockwork.
- the clockwork 10 can also be radio-controlled, for example. Only its asymmetrical mass distribution with respect to the pointer axis 5 is essential.
