Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair cover used for a chair or the like which is located away from an audio device such as a television, and is equipped with a speaker so that the sound can be heard by the listener's ear. It is a device that allows you to listen at a low volume.

[0002]

2. Description of the Related Art For people who dislike wearing earphones and headphones, devices for incorporating a speaker in a seat to listen to television sound and radio include, for example, SAIkai 57-163882, SAIkai 60-133952, and SAIKAIHAI. It is publicly known as 1-175092. However, in the system that can be attached to and detached from the chair without modifying the chair, the structure becomes complicated, and it does not match the general Japanese tea room, and it is currently not popular.

[0003]

(EN) A voice listening device that can be attached to and detached from a chair, yet has a simple structure, which enables easy attachment and detachment, and enables easy manufacturing and inexpensive production.

[0004]

A chair cover for listening to sound according to the present invention is a detachable chair cover for covering the front surface of a backrest of a chair comprising a seat portion and a backrest. The core material of the chair cover is made of a foamed elastic material, and is formed into a substantially flat plate-like body that covers the front surface of the backrest. The surface of the plate-like body is covered with a surface coating material, and the back surface thereof is the surface coating material. A non-slip back surface made of a material having a friction coefficient larger than that of the electro-acoustic conversion element having electric wiring for connecting to an electro-acoustic apparatus is held in a space provided on the left side and the right side of the foamed elastic material. Is.

[0005]

[Function] When the speaker is attached to the chair, it becomes a large-scale thing such as making a hole in the chair to incorporate the speaker, or providing a leg to the speaker to hold it outside the chair. It will be The inventors have thought that if a surprisingly simple attachment / detachment means could be realized by breaking away from the conventional attachment / detachment means, it would be widely popularized, and the inventors arrived at the next idea. The idea is to simply omit the mechanism for attaching (locking) the speaker to the chair, set it to zero, and place the cover with the speaker on the chair. However, if the cover is simply placed on a chair, the cover will move during use and "slide down" will occur. INDUSTRIAL APPLICABILITY The present invention makes it possible to realize a speaker mounting cover having a slip-preventing function so that the speaker mounting cover is not placed on the chair while being simply put on the chair. As will be described in Examples below, the chair cover for listening to sound of the present invention has a back surface formed of a material having a larger friction coefficient than the surface covering material to form a non-slip back surface. Even if you change your body position or posture, the surface covering material will slip with the person, the chair and the back surface will not slip, and you can simply put the voice listening chair cover on the chair and use it on the chair. You can do it, and when not in use, you can return it to an ordinary chair by holding it by hand and picking it up.

FIG. 2 shows a chair cover-1 for listening to a voice according to the present invention.
It is explanatory drawing explaining the use condition of 0, and when a person sits on a chair and puts the head 18 on the chair cover 10,
Conveniently, the cushion material 19 of the chair is recessed in the direction of the arrow by the weight of the human head, and the chair cover 10 is curved so that both ends approach the direction of the human ear 20 and are easily oriented toward the ear. To be oriented.

[0007]

【Example】Example 1  In FIG. 3, the chair 4 comprises a seat 3 and a backrest 5.
It is a reclining chair. For that backrest 5,
A chair cover 10 that covers the front surface is placed. Chair
The cover 10 is a chair to lean on the backrest 5 of the chair 4.
It is just placed on the child 4, and when it is not needed, as shown in FIG.
All you have to do is remove it by hand.
It is only necessary to place it in the state shown in FIG.
No need to attach and detach.

With respect to the chair 4 located away from the television receiver, the chair cover 10 placed on the chair 4 is the radio 2
Alternatively, the electric wire 1 has a terminal (not shown) connected to the television receiver audio circuit, but since the position where the electric wire 1 is arranged and the size of the electric wire 1 are not related to the function of the present invention, the electric wire 1 shown in FIG. In FIG. 16 (described later), the illustration of the electric wire 1 is omitted. The speaker connected to this electric wire 1 is buried at a position near the human head shown by broken lines A and B in FIG. 5, but is not visible from the surface. The radio device 2 may be, for example, a radio that listens to general broadcasts, or a receiver that receives an audio signal from an audio signal transmitter included in the television. Needless to say
Since the speaker A and the speaker B can be independent voice circuits, a perfect stereophonic sound can be obtained, and the sound is a stereophonic sound which is more than a stereo of a system in which two speakers are arranged in a room. A new listening device that is acoustic and can enjoy stereophonic sound without earphones or headphones is obtained.

The chair cover 10 is as shown in FIG. 5 (plan view and bottom view), FIG. 6 (symmetrical side view), FIG. 7 (front view seen from the head), and FIG. 8 (rear view). Is formed in a substantially plate-like rectangular shape, and a portion (lower portion) facing the seating portion forms a thin portion 17 having a thickness gradually reduced toward the end. Although the chair cover 10 is used as a commercially available seat chair, a reclining chair, or the like, even if the commercially available chair has various sizes, the chair cover of the present invention does not have any locking mechanism between the chair cover and the chair body. Since it is not provided, there is an advantage that it can be easily adapted to various commercially available chairs.

FIG. 1 shows a part of the cross section of a chair cover for listening to voice according to the present invention, which is an enlarged view of the vicinity of the portion shown by broken lines A and B in FIG. The base material which is the core material of the chair cover 10 is made of the foamed elastic material 8 and is formed into a substantially flat plate shape. The surface of the foamed elastic material 8 is a surface covering material 7 made of, for example, a woven fabric, a knitted fabric or a non-woven fabric. The back surface is covered with a non-slip back surface material 9a such as a material having a friction coefficient larger than that of the surface coating material 7, for example, a soft rubber film, a rubber material coating cloth, or a fiber material having many irregularities, or a non-slip back surface. By exposing the foamed elastic material 8 without using the material 9a, the anti-slip back surface 9 having a large friction coefficient is formed.

The speaker A or B is a plate-shaped foam elastic material 8
It is held in a space appropriately provided on the left and right of the upper part (a part near the human head), and in this embodiment, as shown in FIG. Fill B. In the figure, 15 is a space for filling the vibration part of the speaker, and 16 is a space for filling the drive part such as a magnetic coil. Since the structure of the loudspeaker is not limited, the loudspeaker may be, for example, an electroacoustic conversion element that is deformed by energization, for example, a plate-shaped sounding body made of an electrostrictive element. In this embodiment the cavity is formed as a recess, but the cavity may be hollow, for example.

As shown in FIG. 2, it is convenient for a person to sit on a chair and place his head 18 on the chair cover 10.
The chair cushion 19 is recessed in the direction of the arrow due to the weight of a human head, the chair cover 10 is curved so that both ends approach the direction of the ear 20, and the built-in speaker comes close to the ear, and Orient it so that it is easy to face it. In order to bring the loudspeaker closer to the ears, it is also possible to carry out the second and third embodiments described below.

[0013]Example 2  In the configuration of the first embodiment, the second embodiment is shown in FIGS.

To do.

The present invention can be achieved by the means shown in each of the above embodiments, but an extra material may be added to the chair cover. Only the extra material is used and does not significantly change the effect of the invention. FIG. 16 shows an example thereof, in which a seat cover 21 extending from the lower end of the chair cover of the present invention is added. The seat cover 21 does not have any audio listening equipment installed, so it is unrelated to the voice function, but if you consider the effect, a person sits down on the seat and presses it down, so the cloth-like anti-slip described above. Back material 9
In some cases, the object can be achieved to some extent without forming the anti-slip back surface such as a (for example, the back surface is the same material as the surface covering material 7). However, even in this case, the chair cover-1
In many cases, it is preferable that the back side is a non-slip back side.

Through the above-described embodiments, when the chair cover 10 is placed on the chair 4 and used by a human, the portion in contact with the human head is easily soiled by the human head. In order to prevent this and make it washable, for example, a cloth-like back surface covering material 9a and a surface covering material 7 constitute an openable and closable bag, and the foam elastic material 8 can be inserted into and removed from the bag. May be inserted into. In this case, as the means for opening and closing the bag, for example, fasteners (loop densification type attachment / detachment, commonly called Magic Tape [registered trademark],
), Buttons, hooks, and other appropriate opening / closing means. If a piece of white cloth, etc. is placed only on the head and only the piece of white cloth is made replaceable, the white cloth (the same applies below including colored cloth and patterned cloth) side and chair cover 10 side The fasteners, hooks, buttons and button holes may be provided on both sides, and the white cloth may be attached to and detached from the chair cover 10.

When used for watching television, some consideration is required. A drawback of using the output of the earphone jack is that the TV receiver becomes silent when the plug is inserted. Further, when the output of the audio jack is used, the receiver does not become silent, but an amateur may mistakenly connect. Common to both the earphone jack and the audio jack, it is necessary to use an amplifier because a sufficient output cannot be obtained. When an amplifier is used, the sub-speaker may also be used to emit sound into the room in consideration of the person in the room.
When wirelessly transmitting and receiving between the chair cover for audio listening and the television receiver of the present invention, it is necessary to consider avoiding radio wave interference in the vicinity. Further, it is better to have a function of automatically turning off the power after a certain time lag, a function of automatically turning on in response to voice, radio waves, or the like.
For these functions, those generally used for other models such as a cordless telephone may be used.

[0018]

[Effects] As described above, according to the present invention, the operation is easy only by placing the chair cover on the chair, and the human being moves due to the difference in the friction coefficient between the surface covering material and the non-slip back surface. It does not slip and does not require any attachment / detachment mechanism. Also, when removing it, it can be returned to an ordinary chair by simply lifting it by hand. Fortunately, the cushion material of the chair is dented by the weight of the human head, the chair cover of the present invention is also curved, and
Mosquitoes are closer to the ears and more likely to point towards them. Human beings are free from the complexity of wearing earphones and headphones, and can enjoy stereo with a sense of freedom. Also, even in a poor Japanese residential environment, you can watch TV without worrying about your family studying for the exam. In the approaching old-age society, even an old man with reduced hearing ability can raise the volume to a desired volume and watch TV or listen to the radio without hesitation in the neighborhood.
