Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a curtain device, and at the same time as the opening of the curtain, a sound suitable for the start of the day such as refreshing music, chirping of birds, babbling of a stream, etc. This invention relates to a curtain device that can temporarily play a melody or the like on a window.

(Conventional technology) At a window or verandah where the bright morning sun shines,
The moment the curtains are opened, refreshing music or the chirping of birds can be heard momentarily, which is a great way to start the day and create a fulfilling atmosphere. As described above, the applicant is not aware of the existence of a curtain device that improves the added value of the curtain device from the auditory perspective, in addition to the original function of the curtain centered on visual perception.

(Problems to be Solved by the Invention) Conventional curtain devices have been considered exclusively for shielding, light shielding, and indoor interiors, but the present invention solves the problems in the original curtain devices that are visually centered.
While allowing the curtain to perform its original role, it also further improves the effect of the curtain device from an auditory perspective, giving the curtain device a multifaceted effect.
Furthermore, it is an object of the present invention to further improve the performance of a sounding device such as a melody, and to provide a curtain device whose range of use can be expanded.

(Means for Solving the Problems) In order to achieve this object, the present invention has the following configuration.

That is, in the curtain device according to the present invention, among the curtain runners that are attached to the upper edge of the curtain with a predetermined pitch and run along the curtain rail in the guide path, the leading runner located on the opening/closing side of the curtain has the corresponding pitch. A start switch circuit is installed which operates in response to the runner coming into contact with a predetermined member to maintain the closed state of the curtain and, conversely, in response to separation from the predetermined member when the curtain is opened. A sounding unit circuit is installed separately, and the lead runner and the sounding unit circuits are connected by a conductive wire.

(Example) Next, a specific example of the curtain device according to the present invention will be described using the drawings, taking a double-door curtain device as an example.

FIG. 1 is a perspective view of a curtain device embodying the present invention, which is attached to the upper edge of a curtain (not shown) and always travels the longest distance using a curtain rail (not shown) as a guide. A pair of left and right curtain runners 1 and 2 located on the opening/closing side
The pair of curtain runners 1 and 2 come into contact with each other due to the magnetic attraction between the permanent magnet 3 attached to the inner end of the left runner 1 and the magnetized member attached to the inner end of the right runner 2. , leave the curtains closed. Of this pair of runners, right runner 2
A start switch circuit 5 is built inside. For example, this start switch circuit 5 may be connected to the inner end of the right runner 2 (left runner 1
side), there is a contact piece 6 that can be retracted from the inner end surface of the runner.
The limit switch has a contact piece 6 when the inner end surface of the right runner 2 and the inner end surface of the left runner 1 are released from contact.
is projected from the inner end surface of the right runner by the spring force, and the start switch circuit 5 forms a closed circuit state. On the other hand, the contact piece 6, which was in the protruding state due to the contact between the inner ends of the left and right pair of runners 1 and 2, sinks into the runner 2 against the spring force, and the start switch circuit 5 forms an open state. do. It is also possible to use a so-called normally closed switch or the opposite, a normally open switch. This start switch circuit 5 has a jack opening 7 for connecting a conducting wire opened at the lower part of the outer end of the right runner 2. A box 10 containing a sounding unit circuit 11 separate from the right runner 2 containing the start switch circuit 5 is installed on the back side of the opposite end of the curtain or on a wall near the opposite side of the curtain. ing.

The main sound unit 11 memorizes a melody that matches the freshness of an early morning, the babbling of a stream, the chirping of small birds, a foghorn in the morning mist, the sound of the ocean at the seashore, etc. A storage medium 1 equipped with a logic circuit 12 that activates an automatic stop function after the flow of
3. For example, an LSI (ADPCM or PCM), a speaker 16 with a volume adjustment mechanism 15, a power source 18, such as a battery, a main switch 20 that controls the entire sound generation unit circuit 11, and a main switch 20 that controls the entire sound generation unit circuit 11, and the sound generation unit circuit 11 and the start. It is provided with a jack port 22 for a conducting wire to which the switch circuit 5 is connected. The start switch circuit 5 in the runner 2 and the sounding unit circuit 11 housed in the box 10 are connected by inserting jacks 8, 25 provided at both ends of a conducting wire 24 into a pair of jack openings 7, 22.

This conducting wire 24 is located at the upper edge of the curtain C,
By locking the curtain C to a group of hooks H suspended from a runner R running with the curtain rail L as a guide, the wiring can be extended, and the presence of this lead wire can be made to not particularly interfere with the opening and closing of the curtain. (See Figure 3).

FIG. 2 is a circuit diagram of a sounding unit equipped with a start switch in the curtain device of the present invention. In a situation where the main switch 20 is closed, the curtain is brought into the closed state by the contact between the pair of runners 1 and 2. Due to the opening of the hot curtain, the contact piece 6 is separated from the right runner 2 from the left runner 1.
The start switch circuit 5 is activated by the protrusion of the
At the same time, a start signal is sent to the logic circuit 12. LSI1 which is a storage medium from the logic part
3, a signal for sound generation is issued.

That is, by assembling the logic circuit 12, for example,
One of the multiple sounds pre-stored in LSI 13
The LSI1 from the logic section selects the th note.
Give a signal to 3. After the first sound has been produced, the signal is fed back from the LSI 13 to the logic circuit 12, and the system waits for the next signal to be produced. Repeat this kind of work,
The sounds stored in the LSI 13 are sequentially produced. When this sound generation work is not necessary, by turning off the main switch 20, the curtains can be opened without sound generation.

Note that the sound produced by the LSI 13 is generated by cutting off the sampling frequency using a low-pass filter 14.
Removes high-pitched noise inherent in waveforms digitized and stored in the LSI 13.

The volume of the sound that has passed through the low-pass filter 14 is controlled by a variable resistor 15, and the amplifier 19
The amplified pronunciation flows out from the speaker 16 with a refreshing tone.

(Effects of the Invention) The present invention floods the window with refreshing tones at the same time as the opening of the curtains, creating an atmosphere suitable for the start of the day. We were able to extend this to the realm of vision. In addition, in the case of this device, the sounding unit can be connected to a curtain runner, etc.
By adopting a structure that is installed separately from the conventional curtain device, it is possible to install various mechanisms essential for creating refreshing sounds, such as large speakers and a volume control device, which creates a pleasant tone. It became possible to play. Also, in the curtain device, the start switch circuit installed on the leading curtain runner and the sounding unit circuit installed at a distance from the leading runner are connected by a conductor wire, so that the length of the conductor wire can be adjusted according to the curtain width. This problem can be solved by extending the length of the curtain, and by extending the wiring by hooking the conductor wire to the hooks, which are essential components of the curtain device, the conductor wire does not get in the way of opening and closing the curtain. By arranging the conductive wire on the back side of the curtain device, the fear of spoiling the appearance of the curtain device is also eliminated.
