Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic opening type Western umbrella provided with a synthetic music output device.

[Conventional technology and problems]

Conventional Western umbrellas are simply used to protect from the rain, and are simply opened when in use and closed when not in use.

To provide this hobby element, it is well known to have a music box attached to a western umbrella, which was a mechanical mechanism that played music by rotating a drum.

The conventional umbrella equipped with the mechanical music box described above can play music when the user desires, but since it is a mechanical mechanism, it has the disadvantage of increasing the weight of the umbrella.

Further, in this conventional example, there is a problem in that the user has to operate the operation button of the music box each time to output music, and furthermore, the power must be stored by winding the spring.

In this regard, an automatic opening umbrella equipped with an electric synthesized music output device is known from Japanese Utility Model Application No. 60-25419. In this known example, a synthesized music output device including a speaker and a battery is built into the handle of a Western umbrella, and its operating contacts are opened and closed by a push button for opening and closing the Western umbrella. Therefore, according to this known example, the drawbacks caused by the mechanical music box and the like can be overcome. However, this known example poses the following new problem.

That is, since all the devices for generating synthesized music are built into the handheld, a conventional general-purpose handheld cannot be used as is, and the handheld must be designed and manufactured as a dedicated handheld.
Due to the structure in which the electrical contacts are opened and closed by push buttons, the contacts must be installed inside the center rod that is inserted into the hand, and it is extremely difficult to install the contacts in the narrow space inside the center rod. When using an open umbrella, your hands are exposed to the wind and rain, so there is a risk of electrical circuit short-circuiting.

[Means for solving problems]

The present invention provides an automatic opening type Western umbrella that can solve all the above problems, and the means for this purpose is to pivot the main rib 3 to the upper potter's wheel 2 fixed to the center rod 1, and A jump spring 6 is interposed between the middle potter's wheel 4 and the lower potter's wheel 5, which can freely slide on the rod, and the tip of the support bone 7, which is pivoted to the middle potter's wheel 4, is pivoted to the middle part of the main rib 3, and the lower potter's wheel In an automatic umbrella in which the tip of the cob 9, which is pivoted to the shaft 5, is pivoted to the middle part of the support bone 7: the receiving tube 16 is fixedly located directly under the upper potter's wheel 2; A sliding cylinder 18 is located directly below the cylinder 16 and is slidably provided on the middle rod 1, and when the umbrella is opened, the sliding cylinder 18 is pushed up by the middle wheel 4 and fitted into the receiving cylinder 16. A compression spring 19 is interposed between the two cylinders 16 and 18 so that the sliding cylinder 18 slides downward and returns when the umbrella is closed. mutually, a pair of contacts 20

〔Example〕

FIG. 1 shows an automatic opening type umbrella in which the present invention is implemented. The western umbrella is provided with a fixed upper potter's wheel 2 near the upper end of a middle rod 1, and a rib 3 is pivotally attached to the upper potter's wheel 2. The middle rod 1 is provided with a freely slidable middle potter's wheel 4 and a lower potter's wheel 5, and both potters' wheels 4 and 5 are urged by a jump spring 6 in a direction away from each other. A support bone 7 is pivotally attached to the middle potter's wheel 4,
The tip of the support bone 7 is pivotally attached 8 to the middle part of the main rib 3. Further, a cochlear bone 9 is pivotally attached to the lower potter's wheel 5, and the tip of the cochlear bone 9 is pivotally attached to the midway part of the supporting bone 7.
has been done. A handle 12 is fixed to the tail end of the middle rod 1, and a locking piece 13 of a retractable repellent 12 is protruded from the middle rod 1 near the hand.
A push button 14 is provided at the tail end of the repellent 12.
An umbrella cloth 15 is stretched over the main rib 3.

In such an automatic opening type Western umbrella, a synthetic music output device is fixed to the umbrella cloth 15, and an operating mechanism for operating the device is linked to the opening operation of the Western umbrella.

2 to 4 show one embodiment of the operating means of the synthesized music output device, which has a receiving tube 16 positioned directly below the upper potter's wheel 2 and inserted onto the middle rod 1. This receiving tube 16 is made of an insulating material such as synthetic resin, is fixed to the upper potter's wheel 2 or the middle rod 1, and is fixed without sliding with respect to the middle rod.
It has a cylinder portion 17 that opens at the bottom. A sliding tube 18 is provided directly below the receiver tube 16, and the sliding tube 18 is similarly made of an insulating material such as synthetic resin, and is slidably fitted onto the inner rod 1. , the upper part of the sliding tube 18 is fitted into the cylinder portion 17 so as to be movable forward and backward. Note that the sliding tube 18 may have a larger diameter than the receiving tube 16, and may be configured to fit into the outer circumferential portion of the receiving tube 16 so as to be able to move forward and backward. A compression spring 19 is interposed between the sliding tube 18 and the receiving tube 16, and this urges the sliding tube 18 in a direction away from the receiving tube 16 (downward in the figure). Thus, the receiver 16 has a pair of contacts 20a and 20b on the inner surface of the cylinder portion 17.
A ring-shaped conductor 21 made of a conductive material is fitted onto the outer periphery of the sliding tube 18 located below it. This conductor 21 preferably has elasticity that allows it to expand and contract in the radially inward direction of the sliding tube 18 .
The contacts 20a and 20b are connected to the power source of the synthesized music output device 23 through circuits 22a and 22b formed by lead wires or the like, respectively. This synthesized music output device 23 plays predetermined electronic sound music for a predetermined time only, and includes a music and/or voice synthesis LSI 24 as shown in FIG. 4, for example.
This is an LSI that outputs desired synthesized music under digital control.The data of the music to be output is stored in memory in advance, and is read out at the time of synthesis, and the music is synthesized and output using digital signal processing. That is, the music synthesis LSI 24 is controlled by the microcomputer 25. external or built-in
Data necessary for music synthesis stored in the ROM 26 is read out. This data is decoded by the decoding circuit in the LSI, interpolated by the interpolation circuit, outputted as synthesized music of the digital signal by the digital filter via the excitation signal generation circuit and parameter register, and then converted from digital to analog. After that, the synthesized music is amplified by an amplifier 27 and outputted from a speaker 28 as synthesized music.

The synthesized music output device 23 is preferably covered with an exterior fabric 29 and attached to the inner surface of the umbrella fabric 15. More preferably, the exterior cloth 29
Corresponding to this, decorative cloth 3 such as a wax pen with the same shape as this
0 is placed on the outer surface of the umbrella cloth 15, and the decorative cloth 30 and the exterior cloth 29 are integrally attached with the umbrella cloth 15 in between.

According to this embodiment, when the Western umbrella is closed, the middle potter's wheel 4 and the lower potter's wheel 5 are located closer to the hand of the center rod 1, and the lower potter's wheel 5 moves the engagement window 31 through the repellent 1.
Since it is locked to the engagement piece 13 of 2, the sliding tube 18
is urged downward by the spring 19 as shown in the second figure, and the conductor 21 is separated from the contacts 20a and 20b, so that the power to the synthesized music output device 23 is cut off and the device 23 is not operating. do not have.

From this state, if you press the push button 14 to open the umbrella,
The middle potter's wheel 4 and the lower potter's wheel 5, which have been released from the engagement piece 13, slide upward along the center rod 1 by the jump spring 6 to open the main rib 3, and the middle potter's wheel 4 hits the sliding tube 18. I guess. Therefore, the sliding tube 18
As shown in FIG.
a and 20b in contact with each other. When this contact passes, the pair of contacts 20a and 20b become conductive, and as a result, the synthesized music output device 23 receives power from the power source and operates, playing predetermined music for a predetermined time. This synthesized music is output from the inner surface of the umbrella cloth 15 above the user's head. In this way, the contacts 20a and 20b of the receiving tube 16 and the conductor 21 of the sliding tube 18 constitute an operating mechanism that operates the synthetic music output device 23, and this mechanism is linked to the opening operation of the umbrella. ing.

[Effect of idea]

As a result of the above-described configuration, the present invention has the following effects.

Conventionally, for a general-purpose automatic opening type Western umbrella, in addition to the synthetic music output device 23 to be attached to the umbrella cloth, etc., the component parts are a receiving tube 16 with a compression spring 19 interposed therein and a sliding tube 18. Since it is only necessary to additionally prepare the members of the set, there is no need to make any changes to the constituent parts of the umbrella itself, and its manufacture is easy.

In addition, since the additionally prepared parts can be easily assembled to a conventional general-purpose automatic opening type western umbrella at a position where it can be easily attached, the present invention is easy to implement.

Furthermore, since the receiving tube 16 and the sliding tube 18, which constitute the operating means for the contacts 20a and 20b, are located directly below the upper potter's wheel 2, the operating means is least affected by wind and rain among Western umbrellas. Therefore, accidents such as short circuits of contacts can be prevented as much as possible.
