JPS6033416Y2 - Travel or desk clock with alarm device and clock casing - Google Patents

Abstract

A time measuring device, more particularly a travel clock or table alarm clock, having a casing (1, 2), is provided with an operating press key for switching an alarm device on or off, in which the press key is arranged on the upper side of the clock casing (1) and comprises a switching rocker (7) having a width which corresponds to the width (b) of the clock casing and a depth which is over one half of the thickness (t) of the clock casing. The switching rocker (7) is tiltable between a first position and a second, depressed, position about an axis (8) which extends substantially parallel to and at a spacing from the front face (3) of the clock casing. When the rocker is depressed to render the alarm operative, a mark (12) on the rocker is hidden by the case part (1) and a projection (14) on the case passes through an aperture (15) in the rocker and can be felt in the dark. <IMAGE>

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a travel or desk clock having an alarm device and a clock casing.

A desk alarm clock with a casing of approximately right angle parallelepiped is known from the prior art (Utility Model No. 76076 of the Federal Republic of Germany).
(See specification No. 701).

In this known desk alarm clock, a device for connecting and disconnecting the alarm device is configured as a key switch and is arranged on the front side of the clock casing alongside the dial.

This arrangement of the key switch has the disadvantage that the watch casing must be grasped when connecting and disconnecting the alarm device.

This is because otherwise the clock would be displaced from its position or turned over before the key switch has moved to the intended switching position.

Table-top alarm clocks are also known in which the device for connecting and disconnecting the alarm device is constructed as a pushbutton switch arranged on the top side of the clock (see German Patent Application No. 25 285 021).

In this desk alarm clock, the size of the push button is small, so especially in a dark room or at night, the user must first find the push button by touch.Moreover, the user cannot wake up at the moment he or she looks for the push button. A disadvantage is that it is not possible to ascertain with certainty whether a device is connected or disconnected.

Furthermore, according to US Pat. No. 3,460,421, an alarm clock of the type in which a switching tilting plate is provided on the upper side of the watch casing, which is pivotable about an axis extending parallel to the front edge of the watch casing. is publicly known.

The switching tilt plate extends over most of the width of the watch casing.

The alarm device is connected or disconnected by pivoting the switching plate from its one end position to its other end position.

For this purpose, the switching tilting plate has on its underside two fingers that engage in corresponding openings provided in the movable plate, and the movable plate itself also has a cutout. One arm of a two-armed lever engages with this notch, and the other arm moves the magnetic vibrator toward or away from the excitation coil. It looks like this.

However, this device for connecting and disconnecting the alarm device is relatively expensive to manufacture due to its relatively complex mechanical structure and is prone to failures.

Problems to be solved by the present invention The problems of the present invention are that it is easy to operate even in a dark place, the user can easily check whether the alarm device is connected or disconnected, and the mechanical An object of the present invention is to provide a device for connecting and disconnecting a self-aware device, which is configured as a switching tilting plate and is simple in structure and inexpensive to manufacture.

Means for Solving the Problems The present invention has solved the above problems, and the length of the switching tilting plate is approximately equivalent to the width of the watch casing, and the switching tilting plate is provided with a protrusion, and the protrusion is The watch casing is supported in notches provided on both sides of the watch casing, and a rib is provided on the lower side of the switching tilting plate, and a thick wall portion is integrally molded on both sides of the rib. Two projections are provided on the top surface, the ribs are adapted to engage between the mutually facing sides of these projections, and the two projections provided on the top surface of the watch casing are arranged so that the ribs engage between the mutually facing sides of the projections. Based on the spring force acting on the thick walled part of the rib through the side surface, when a force is applied to overcome the frictional force formed by this spring force, the switching tilting plate is moved from both ends around the axis. Configured to pivot between positions.

In order to be able to clearly check the respective position of the switching tilting plate, according to one embodiment of the present invention, an indicator is provided on the front edge of the switching tilting plate, so that the switching tilting plate can be pushed downward. The indicator enters into the rear side of the face of the watch casing together with the front edge of the switching tilting plate, so that the indicator is no longer visible.

Embodiments and Operations Next, the structure and operations of the present invention will be specifically explained with reference to the embodiments shown in the drawings.

The watch casing includes a box-shaped front part 1 open at the top, a rear part 2 connected to the front part 1, a dial 4 disposed on the front face 3 of the watch casing, and a front part 1 of the watch casing. The switching tilting plate 7 is tiltably supported by notches 5 and 6 provided in the switching tilting plate 7.

To operate the alarm device, the switching tilting plate 7 is tilted about the axis 8 in the direction of the arrow A.

For this purpose, this switching plate 7 is provided with lateral projections 9, 10 which engage in recesses or recesses 5.6 provided on the sides of the front part 1. existing or supported.

Therefore, when the switching plate 7 is pivoted about the axis 8 in the direction of the arrow A, the alarm device is operated.

As a result, the front edge 11 of this switching tilting plate 7 is lowered into the inside of the watch casing, and the indicator 12 provided on the front edge 11 is hidden inside the casing, so that the user can switch by simply looking at the front 3 of the watch. It is possible to confirm which switching position the tilting plate 7 is at.

This tilting switch plate 7 has a window-like cutout 15 in the vicinity of its front edge 11, and when the tilt switch plate 7 is pushed up in the direction of arrow A or in this pushed down switching position, A stationary pin 14 provided in the casing projects from the notch 15.

This pin 14, which can be easily located by touch, indicates the switching position of the switching tilt plate in the dark.

As shown in FIG. 3, the switching tilting plate 7 has its lower surface 18
It has ribs 19 on both sides thereof, which have thickened parts 20 resembling push-up buttons, and these thickened parts 20 correspond to projections 23, 24 on the upper surface 25 of the watch casing.
is adapted to contact the side walls 21,22 of.

These projections 23, 24 have a certain spring action, so that when pivoting the switching tilting plate 7 about the projections 9, 10, the switching tilting plate 7 is forced to move only after a certain resistance has been overcome. A braking action is applied such that the switching tilting plate 7 cannot be tilted.

Moreover, this switching tilting plate 7 has fingers 26,
When the switching tilting plate 7 is tilted, this finger 26 passes through a window-like opening 27 in the upper surface of the watch casing and acts on the electrical switching contacts (not shown in detail) of the clockwork. There is.
