Description

[Detailed description of the invention] The present invention relates to a cuckoo clock, and is configured so that when the top lid returns from the open leg position to the closed leg position due to its own weight, the cuckoo cuckoo is struck by the opening action of the top cover that activates the cuckoo whistle. , which added a new commercial value to the cuckoo clock by producing a striking sound that did not overlap with the sound of the cuckoo whistle.

Conventional cuckoo clocks are designed so that the cuckoo body enters and exits at a set time through a door installed in the outer box, and an audio alarm mechanism linked to the bellows is activated, as if the cuckoo body was making a time signal. things are becoming mainstream.

However, recently, users have been keenly looking for something that has other elements added to such a conventional orthodox mechanism.

This invention aims to satisfy the needs of such users, and its purpose is to add a new commercial value to cuckoo clocks by generating a striking sound in addition to the conventional cuckoo whistle sound. There is a particular thing.

In order to achieve the above object, the present invention consists of a bellows that activates a pigeon whistle when the top cover returns from the open leg position to the closed leg position due to its own weight, a ring and a bell striking member, and a push-up rod at the end of the top cover of the bellows. A fulcrum part is provided between the fixed part and the tip of the push-up bar, and the push-up bar is fitted loosely so that the push-up bar can pass through, and the bell-striking member is moved up by the push-up bar as the top cover is opened. It is characterized by being driven.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is an explanatory diagram of the striking structure of a cuckoo clock according to the first embodiment of the present invention, and FIG. 2 is an explanatory diagram of the striking structure of the cuckoo clock according to the second embodiment.

The top cover 2 of the bell whistle 1 is opened and closed a predetermined number of times at regular times by a drive device (not shown) that is linked to a clock wheel train. In this operation, when the top lid 2 returns from the open leg position to the closed leg position due to its own weight, the pigeon whistle is activated and a warning sound is made. A push-up bar 3 is swingably fixed to the upper lid 2, and a fulcrum washer 4 is loosely fitted to the push-up bar 3. The fulcrum washer 4 is loosely fitted onto the push-up rod 3 so as to be able to pass therethrough, and is fixed to the outer box of the cuckoo clock (not shown).

The drive lever 10 is swingably fixed to a rotating shaft 5 installed in the outer box of the cuckoo clock. The drive lever 10 has an engaging portion 11 and a connecting portion 12 at both ends. Tip 3a
This position is set by a stopper 6 mounted on the outer box of the cuckoo clock.

The ring 23 is fixed to a fixed part 21 at the tip of the lever 20 which is swingably fixed to the rotating shaft 7, and a hitting ball 24 is suspended from a position inside the ring 23 of the fixed part 21.

The shuttle lever 20 has the above-mentioned fixing part 21 of the ring 23 and a connecting part 22, and is urged in the direction of arrow F by a return spring 25. and are connected by a connecting rod 15.

The present embodiment has the above structure, and its operation will be explained next.

The top cover 2 of the bell whistle 1 is opened and closed a predetermined number of times at regular times by a drive device (not shown) that is linked to a clock wheel train.

At this time, when the upper lid 2 is opened to position A, the push-up bar 3, which is swingably fixed to the upper lid 2, rises while passing through the fulcrum washer 4, and the tip 3a of the push-up bar 3 is attached to the drive lever. 10 and rotates the drive lever 10 in the direction of arrow D to the position shown by the chain line. This rotation is transmitted to the lever 20 via the connecting rod 15, and the lever 20 and the link 23 rotate in the direction of arrow E to the position shown by the chain line against the biasing force of the return spring 25.

From this state, the upper lid 2 of the figurine 1 further opens its legs and rises to the position shown in B. In this process, the tip 3a of the push-up rod 3 moves up along the trajectory shown by arrow C using the fulcrum washer 4 as a fulcrum. Therefore, the engagement between the drive lever 10 and the tip end 3a of the push-up rod 3 is released at the position shown by the chain line. As a result, the lever 20 and the link 23 rapidly rotate in the direction of arrow F due to the restoring force of the return spring 25, and this rotation is stopped when the drive lever 10 contacts the stopper 6.

At this time, the hitting ball 24 hits the inner wall of the ring 23 and a hitting sound is generated, and thereafter the top cover 2 of the funnel 1 is opened and closed a predetermined number of times, and the above-mentioned operation is repeated.

In this embodiment, the pigeon whistle makes a sound when the top lid 2 returns under its own weight from its open leg position shown at B to its closed leg position shown by a solid line. For this reason, the bell is struck before the cuckoo whistle operates, and the sound of the cuckoo whistle and the sound of the bell do not overlap, creating a new sound effect not found in conventional cuckoo clocks.

FIG. 2 is an explanatory diagram of a cuckoo clock striking structure according to a second embodiment of the present invention.

The bellows 30 operates a pigeon whistle as in the first embodiment, and its top cover 31 is opened and closed a predetermined number of times at regular times by a drive device (not shown) that is linked to a clock train. The upper lid 31 has a first
As in the embodiment, the push-up bar 32 is swingably fixed, and the push-up bar 32 is connected to the cuckoo clock outer box (not shown).
It is loosely fitted into a fulcrum washer 33 fixed to the fulcrum washer 33 .

The drive lever 40 is swingably fixed to a rotating shaft 37 installed in the outer box of the cuckoo clock, and the engaging portion 41
and a drive section 42 at both ends thereof. The engaging portion 41 of the drive lever 40 is connected to the upper lid 31 of the figure 30.
When the push-up bar 32 rises with the opening of the legs, the push-up bar 3
It is located at a position where it engages with the tip 32a of No. 2.

At the top of the shaft 50 is a protrusion 56 and a doll 57.
is fixed to the doll 57, a shimoku 52 is fixed to the doll 57, and a rotating lever 51 is installed at the bottom. The shaft 50 has a shaft hole 36 formed in the support plate 35 and a bearing 3 fixed to the cuckoo clock outer box.
4 and is rotatably supported.

The shaft 50 is moved in the direction of arrow J by the return spring 55.
This biasing in the direction of arrow J is restricted at the position shown in the figure by contact between the projection 56 and a stopper 38 erected on the support plate 35. In this position, the rotary lever 51 of the shaft 50 is engaged with the drive portion 42 of the drive lever 40.

Further, the ring 54 is fixed at a position on the support plate 35 corresponding to the hitting ball 53 at the tip of the shake 52 of the doll 57 fixed to the upper part of the shake shaft 50.

The present embodiment has the above structure, and its operation will be explained next.

The top cover 31 of the bellows 30 that operates the pigeon whistle is opened and closed a predetermined number of times at regular times by a drive device (not shown) that is linked to a clock wheel train.

As the upper lid 31 opens, the push-up bar 32 rises, and the tip 32a moves along a trajectory indicated by an arrow G.

Therefore, the tip 32a of the push-up rod 32 rotates the drive lever 40 in the direction of arrow H to a certain position. As a result of this rotation, the driving portion 42 of the drive lever 40 engages with the rotary lever 51 of the shaking shaft 50, and rotates the shaking shaft 50 in the direction of the arrow against the restoring force of the return spring 55.

From this state, as the upper cover 31 is opened, the push-up bar 32
continues to rise further, the tip 32a of the push-up rod 32
The drive lever 40 is disengaged from the engagement portion 41. As a result, the shaking shaft 50 rapidly rotates in the direction of arrow J due to the restoring force of the return spring 55. This rotation is stopped when the protrusion 56 fixed to the shaft 50 comes into contact with the stopper 38, and at this time, the shaft 52 is elastically deformed.
The ball 53 at the tip hits the ring 54 and a striking sound is generated. From then on, the upper lid 3 of the Figo 30 will be used a specified number of times.
1 opens and closes and repeats the above operation.

In this embodiment as well, the pigeon whistle makes a sound when the top lid 31 returns from its open leg position to its closed leg position due to its own weight.For this reason, the ringing of the bell is performed before the pigeon whistle operates, and the sound of the pigeon whistle and the ringing sound are different. A new sound effect not found in conventional cuckoo clocks is created without duplication.

As explained above, according to the present invention, the push-up bar is swingably fixed to the top lid of the bellows that activates the pigeon whistle when the top lid returns from the open leg position to the closed leg position due to its own weight, and the push-up bar is swingably fixed to the top cover of the bellows to operate the leg opening operation of the top cover. As the push-up rod rises as the cuckoo clock rises, the cuckoo is driven to strike the bell, so the cuckoo clock can generate a striking sound without overlapping the sound of the cuckoo whistle, adding a new commercial value to the cuckoo clock.
