Description

[Detailed description of the invention] (Industrial application field) The present invention mainly relates to interiors and action clocks, and is particularly concerned with revealing or concealing the characters inside the case body by opening and closing the lid body. The present invention relates to a ring-stopping mechanism for an alarm clock that has a function of setting off or stopping an alarm or a music box.

(Prior art) The conventional ring stop mechanism for an alarm clock consisting of an opening/closing lid is operated by hand on a ring stop button and switches the switch contacts independently of the opening/closing operation of the lid. It was not possible to change the switch contact point by manually operating a means other than the button, such as opening and closing the lid.

Also, if the stop button, lever, switch contact, etc. are housed in a single block body, there is no need to provide a separate switch body, but if you do this, you will have to change the shape and size of the stop button every time. The design of the switch contact portion must be newly changed, resulting in poor efficiency and a drawback that limits the degree of freedom in design.

(Technical Issues) The present invention was developed in view of the shortcomings of the prior art, and the on/off switching operation of a single switch body can be changed over multiple times by using means such as opening/closing the lid body. The technical problem is to improve the simplicity of the ring-stopping operation based on its multifunctionality by providing a mechanism that can switch from one route to another.

(Technical means) In this invention, in order to solve the above technical problem,
In an alarm clock having a cover body with a character or the like attached to the case body, the stop button and lever are tensioned and energized by a compression coil spring, and the stop button and lever are placed in a wedge-shaped receiving part. The stop button and the lever are interlocked by being supported by the lever, and the lever is operated by an opening/closing operation of the lid body as another means,
It is configured so that a stop button is interlocked with the lever, and a switch body separately provided on the outer periphery of the stop button or the lever is switched. As shown in Figure), the configuration is as follows.

Reference numeral 1 denotes an alarm clock body comprising an opening/closing mechanism for a lid body (not shown), and a case body 2 houses appropriate characters inside the alarm clock body.

Reference numeral 3 denotes an arm whose upper end is connected to the lid (not shown), and when the lid is opened and closed, the shaft 3A of the arm 3 slides vertically inside the guide rib 4 of the case body 2. It is configured to move and rotate in an eccentric angle about the shaft rod 3A as the central axis.

Reference numeral 5 denotes a claw body rotatably attached to the lower end of the arm 3 with a pin 6. A restoring spring 7 is partially wound around the pin 6, and one end 7A of the restoring spring 7 is attached to the claw. By engaging a part of the body 5 and by engaging the other end 7B of the restoring spring 7 to a part of the arm 3, the claw body 5 is constantly rotated in the direction of arrow A with respect to the arm 3. It has been created to assist.

8 is a stop button, and this wedge-shaped shaft protrusion 8A is connected to the opening part 9A in the upper plate 9 of the case body 2.
It is rotatably supported by a wedge-shaped receiving portion 10 provided near the.

Reference numeral 11 denotes a leaf switch, and when the stop button 8 is pushed in the direction of arrow B, the leaf switch 11 is turned on, and when it is pushed in the direction of arrow C, the leaf switch 11 is turned off. .

Reference numeral 12 denotes a lever with an on display section 12A and an off display section 12B at one end, and a wedge-shaped shaft protrusion 13 provided approximately in the center of the lever 12 is biased toward a wedge-shaped receiving section 14 of the mounting body 18. It is supported so that it can rotate freely. Alternatively, the leaf switch 11 may be provided within the rotation range of the lever 12 so that the lever 12 can be used to turn on and off.

Reference numeral 15 denotes a compression coil spring which is stretched between the squeal stop button 8 and the lever 12 and near the wedge-shaped shaft protrusions 8A and 13, respectively, and one end 15A of the compression coil spring 15 is connected to the squeal stop button. 8, and the other end 15B is fitted into the shaft cylinder groove 12C of the lever 12, thereby bending the lever 12 into an arched shape.

Thus, the noise stop button 8 and the lever 12 are connected to each other by the tensile elastic force of the compression coil spring 15 so as to be tilted upside down.

That is, when the stop button 8 is pushed down in the direction of arrow B, the midsection 15C of the compression coil spring 15 moves in the direction of arrow H beyond the nodal point, and the lever 12 moves in the opposite direction in the direction of arrow D. When the stop button 8 is pushed down in the direction of arrow C, the lever 12 rotates in the opposite direction in the direction of arrow E, simultaneously turning the leaf switch 11 off. It is accomplished.

Reference numeral 16 denotes a display window bored in the case body 2, and the display portion 12A or 12B of the lever 12 is positioned in the display window 16 by turning the lever 12 at an angular angle.

Further, the tip 5A of the claw body 5 of the arm 3 is within the angular rotation range of the other end 17 of the lever 12.
The other end 17 of the lever 12 comes into contact with the arm 3 when the leaf switch 11 is pushed down and the lid is opened by hand with the leaf switch 11 in the ON position. The claw body 5 is pulled upward, and its tip 5A comes into contact with the other end 17 of the lever 12 to turn it in the direction of the arrow E, at the same time turning the leaf switch 11 off. There is.

Then press the button 8 to stop the leaf switch 11.
At the same time, the switching can also be performed by opening and closing the lid, so the ringing can be stopped by simply opening and closing the lid, without having to take the trouble to open the lid and then operate the stop button.

Further, even if the lid is closed after the alarm clock body 1 is set to the ringing standby state and the ring stop button 8 is turned on and pushed down in the direction of arrow B, the tip 5A of the claw body 5 does not touch the lever 12. However, the claw body 5 resists the expanding elastic force of the restoring spring 7 and escapes by turning in the direction of arrow F, so that the claw body 5 does not touch the lever 12. There is no risk of it becoming an obstacle.

Reference numeral 18 denotes a mounting body having a wedge-shaped receiving portion 14, which is fixed to the upper plate 9 with screws 19.

(effect) The above technical means works as follows.

If you open the lid in advance and set the sound standby state as appropriate, and then push down the sound stop button 8 in the direction of arrow B, the leaf switch 11 will turn on, and the lever 12 will move in conjunction with this, so that the other end 17 will move to the direction of arrow D. It will be in a downward position. Then close the lid.

At that time, a display section 12A indicating an on state is positioned in the display window 16.

Next, when the alarm goes off at the set time and the lid is opened from the case body 2, the shaft rod 3A of the arm 3 slides upward within the guide rib 4, and the lower end of the arm 3 The tip 5A of the claw body 5 is brought into contact with the other end 17 of the lever 12.

At this time, the lever 2 is angularly rotated in the direction of arrow E by the tip 5A of the claw body 5, and the stop button 8 is moved in the direction of arrow C via the compression coil spring 15.
The leaf switch 11 is turned off. At this time, the display section 12B indicating the off state is located in the display window 16.

Therefore, when the alarm clock body 1 is ringing,
The ringing can be stopped by opening the lid.

Also, when the case body 2 is open, the stop button 8 can be pressed.
Therefore, even if the leaf switch 11 is turned on and the lid is closed, the restoring spring 7 provided on the claw body 5 will keep the claw body at the abutting position between the other end 17 of the lever 12 and the claw body 5. Since the lever 5 escapes in the direction of the arrow F, it does not pose any obstacle to the lever 12, and the lid body can be closed. Also, when the lid is closed, the claw body 5
is returned in the direction of arrow A by the compression coil spring 15.

(Effects) The present invention has the following unique effects. In particular, the ringing can be stopped simply by opening the cover of the alarm clock body, in addition to the ringing stop button, making it possible to switch from multiple routes with a single switch, and making it easy to turn off the ringing. There are advantages such as:
