FIG. 2 is a view showing the structure of the portable telephone aid according to the first embodiment, and shows a case where a substantially inverted J-shaped frame 1 is supported by a single holder 2 at one side. FIG.
2A is a plan view thereof, and FIG. 2B is bb in FIG. 2A.
FIG. 2C is a cross-sectional view of FIG. The material of the frame 1 is a light and flexible metal (stainless steel, etc.), titanium alloy, carbon,
It is made of a rod-shaped or plate-shaped member such as resin (plastic).
The frame 1 has a generally inverted J-shape as a whole so that the upper half thereof fits the base of the back of the ear. Further, the lower half (straight) portion of the frame 1 is passed through the through hole of the ferrule member 5 having a rectangular cross section, and the annular plate washers 12a, 1c are inserted into the grooves 11b, 11c provided at two places of the frame 1.
The ferrule member 5 is fixed to the frame 1 by fitting the respective 2b. The ferrule member 5 is provided with a hollow portion on the axial side surface of the through hole, into which the corrugated leaf spring 7 is inserted.

On the other hand, the holder 2 has a hollow portion 22 for slidably supporting the ferrule member 5, and at least one wall thereof has a concave portion 2a for engaging (latching) with the leaf spring 7. , 2b. As the material of the holder 2 and the ferrule member 5, the same resin (plastic), ceramics, metal, or the like as the mobile phone 6 can be used. When the ferrule member 5 fixed to the frame 1 is inserted into the holder 2, the mobile phone assisting device 10 according to the first embodiment is obtained. If necessary, a stopper 2c is provided on the head of the holder 2 (by screwing, bonding, etc.) so that the inserted ferrule member 5 does not come off the holder 2.

In this configuration, when the frame 1 is pulled upward, the ferrule member 5 rises and the frame 1 is fixed at the position where the leaf spring 7 is latched in the recess 2a.
When the frame 1 is pushed downward, the leaf spring 7 comes off from the concave portion 2a, and the ferrule member 5 descends.
The frame 1 is fixed at the position latched at b. Therefore, the frame 1 in this case is stably fixed at two positions, that is, during use and storage. Note that in FIG.

FIG. 3 is a diagram showing the structure of another portable telephone aid according to the first embodiment, showing a case where a substantially inverted J-shaped frame 1 can be fixed at an arbitrary position (height). I have. In FIG. 3 (C), a plurality of recesses are uniformly provided between the recesses 2a and 2b in the hollow portion 22 of the holder 2 so that the frame 1 can be stably placed at arbitrary positions in multiple steps. Can be fixed. In addition, since the height of the frame 1 can be arbitrarily adjusted, the height of the frame 1 is increased (about 2 to 3 cm from the holder 2) so that it is easy to put on the ears. By slightly pushing down the frame 1 (about 0.5 to 1 cm from the holder 2), the ear can be stably sandwiched between the frame 1 and the head of the mobile phone 6. Therefore, the earphone stability of the mobile phone 6 is good.

FIG. 4 is a view showing a mode of use of the portable telephone aid according to the first embodiment. FIG. 4 (A) is a plan view thereof.
FIG. 4B is a front view, and FIG. 4C is a right side view. Here, reference numeral 10 denotes the ear hanging assisting device shown in FIG. 2 or FIG.
In FIG. 4, a part (cheek) f of the user's face and the left ear e are drawn so as to be overlapped by a dashed line.

In the figure, the space between the portable telephone 6 and the holder 2 is bonded with, for example, a double-sided tape 3. If the surface to be bonded of the mobile phone 6 is largely curved, the bonding surface of the holder 2 is curved in advance in accordance with this, or the double-sided tape 3 is thick so as to fill the gaps between them. Use In FIG. 4 (C), preferably, the holder 2 is bonded by being inclined by an angle θ (= about 10 ° to 25 °) from a perpendicular (center line) CL set at the center of gravity of the mobile phone 6.
In this way, the frame 1 is located just above the head of the mobile phone 6 when it is stored, and does not get in the way. In use, the mobile phone 6 is pulled out to the front side of the head and is easily hooked on the ear. If the user releases his / her hand after hanging on the ear, the mobile phone 6 tends to hang directly below the ear hanging portion by its own weight (that is, it attempts to rotate around the ear hanging portion by the angle θ). The portion 6 'is in close contact with the cheek f.

In particular, when the auxiliary tool 10 shown in FIG. 3 is used, the frame 1 is slightly pushed down after the ear hanging,
An ear is sandwiched between the frame 1 and the head of the mobile phone 6. By doing so, the mobile phone 6 is stably supported by the ears, and the speaker 62 at this time is closer to the ear canal, so that it is easier to hear the talk of the other party. Further, the microphone 65 is closer to the mouth so that the user can surely talk with the other party without making a loud voice. In the case where the mobile phone 6 is slightly heavy, if the user leans his / her head slightly to the left side in the figure with the ear rest, the weight of the mobile phone 6 is distributed to the ears e and the cheeks f.
Can be maintained stably for a long time.

Although not shown, it is possible to process the frame 1 in such a manner that it is bent in the vicinity of the outlet portion of the holder 2 in front of one end and then rises upward, so that the frame 1 shown in FIG. Even if the holder 2 is mounted substantially parallel to the center line CL of the mobile phone 6, the frame 1 can be deployed on the front side of the mobile phone 6. Instead of using the double-sided tape 3, bonding with an adhesive, fastening to the mobile phone 6 with a dedicated mounting band, or screwing may be performed. FIG. 4 shows a usage mode in which the ear is put on the left ear. Some people have the right ear. In this case, FIG.
By attaching the holder 2 to the left side of the mobile phone 6 in (B), the holder 2 can be easily hung on the right ear.

FIG. 5 is a view showing the structure of a portable telephone aid according to the second embodiment, in which a substantially inverted U-shaped frame 1 is supported by two holders 2A and 2B. FIG. 5A is a plan view, and FIG.
(A) is a bb cross-sectional view, and FIG. 5 (C) is a cc cross-sectional view. As shown in FIG. 5 (B), the frame 1 has a generally inverted U-shape as a whole so that the upper half thereof fits the base of the back of the ear. As shown in FIG. 5 (C), both ends (straight sides) of the frame 1 are bent at L-shaped ends.
The frame 1 is slidably held by being inserted into the cavity B. As described above, the auxiliary tool 10 has an extremely simple (simple) structure, and can be configured to be small and compact as a whole (particularly, the holders 2A and 2B). In addition, the holder 2 is supported by the structure that
Even if A and 2B are small, the frame 1 can be firmly supported.

With this configuration, when the frame 1 is pulled upward, the frame 1 is fixed at a position where the L-shaped bent portion is in contact with the upper inner wall of the holder 2. When the frame 1 is pushed downward, the frame 1 is fixed at a position where the L-shaped bent portion abuts on the lower inner wall of the holder 2. Therefore, the frame 1 in this case is stably fixed at two positions, that is, during use and storage.

FIG. 5A shows a cross section taken along line c--c of another example of the holders 2A and 2B. This holder 2B (similarly to 2A) is a friction holding member 23 for holding the columnar or plate-shaped lower half of the frame 1 slidably with required friction on, for example, two peripheral surfaces (or the entire peripheral surface) inside the cavity. Is provided. As the friction holding member 23, a plate wall or a tube made of rubber, resin, metal or the like can be considered. The friction applied to the frame 1 is such that when the frame 1 is moved up / down by hand, the lower half of the frame 1 slides in the cavity. However, the one that does not slide may be used. Therefore, after the frame 1 is hung on the ear, if the frame 1 is slightly pressed down, the ear can be stably sandwiched between the frame 1 and the head of the mobile phone 6, and the user can talk without any hand.

The lower side of the holders 2A and 2B may be a through hole. In this case, a long slide length can be obtained even with a short holder effective length. Further, the friction holding member 2
3 are holders 2A. It may be fixed (adhered or the like) inside 2B and / or around the lower half of the frame 1. In addition, such a holder 2A. 2B friction structure, one-sided type mobile phone aid 1 according to the first embodiment
Obviously, it may be applied to zero.

FIG. 6 is a view showing the structure of another portable telephone aid according to the second embodiment, showing a case where a substantially inverted U-shaped frame 1 can be fixed at an arbitrary position (height). I have. In FIG. 6 (C), a plurality of recesses are uniformly provided between the recesses 2a and 2b in the hollow portion 22 of the holder 2B (the same applies to the holder 2A). It can be fixed stably at the position. In addition, since the height of the frame 1 can be arbitrarily adjusted, the height of the frame 1 is increased (about 2 to 3 cm from the holder 2) so that it is easy to put on the ears. Is frame 1
Press down slightly (about 0.5 to 1 cm from holder 2)
Thus, the ear can be stably sandwiched between the frame 1 and the head of the mobile phone 6. Therefore, the earphone stability of the mobile phone 6 is good. In FIG. 6C, since the latch position of the holders 2A and 2B can be adjusted independently of each other in the auxiliary tool 10, the height of the frame 1 after hanging the ears is unbalanced on the left and right. This allows the user to set the mobile phone 6 as desired according to his / her ear shape and preference.

FIG. 7 is a diagram showing a mode of use of the portable telephone aid according to the second embodiment, and FIG.
FIG. 7B is a front view, and FIG. 7C is a right side view. Here, reference numeral 10 denotes the ear hanging assisting device of FIG. 5 or FIG.
A commercially available mobile phone 6 and the holders 2A and 2B are bonded with, for example, a double-sided tape 3. In FIG. 7C, preferably, the holders 2A and 2B are separated from the perpendicular CL of the telephone 6 by an angle θ.
(= About 10 ° to 25 °) and adhered. In this way, when the frame 1 is stored, the frame 1 comes into close contact with just above the head of the telephone 6 and does not get in the way. In use, it is pulled out to the front side of the head of the telephone 6, so that it is easy to put on the ear. When the user releases the hand after hanging on the ear, the mobile phone 6 tends to hang directly below the ear hanging portion by its own weight, and as a result, the portion of the mobile phone 6 ′ adheres to the side of the cheek f as shown in FIG.
Further, the auxiliary tool 10 can be easily hung on the left ear and the right ear as it is. Note that by changing the left and right mounting angles θ, a user's desired mounting feeling (fit) can be obtained.

In particular, when the auxiliary tool 10 shown in FIG. 6 is used, the frame 1 is slightly depressed after the ear hanging,
An ear is sandwiched between the frame 1 and the head of the mobile phone 6. By doing so, the mobile phone 6 is stably supported by the ear, and the speaker 62 and the microphone 65 at this time are closer to the user's ear hole and mouth.

It should be noted that in FIG.
If the width of the commercially available mobile phone 6 using the frame 1 is narrow, the frame 1 may not have a sufficient width to hang on the ear if the frame 1 is strictly substantially inverted U-shaped. In this case, the holders 2A and 2B may be provided thicker to support the frame 1 wider, or the curved shape of a part (both sides) of the frame 1 may be changed, for example, as shown in FIG. May be inflated. It should be noted that the term “substantially inverted U-shape” in the present invention includes such a shape.

FIG. 8 is a view for explaining a portable telephone aid according to another embodiment. The other of a cord provided on a commercially available portable telephone 6 (or one of which is fixed to the portable telephone 6) is slidable. This shows the case of holding. FIG.
In (A), reference numeral 67 denotes a string (usually a ring) provided on the mobile phone 6, the left end of which is fixed (wound) to the body of the mobile phone 6 as usual, and the right end ( Ring side) is free.

Reference numeral 8 denotes a holder made of plastic or the like, which is attached to the side surface of the portable telephone 6 by, for example, a double-sided tape 3 as shown in the figure. FIG. 8A shows a cross section of an example of the holder 8. The holder 8 is a simple one having a through hole having a thickness capable of giving a suitable friction to the string 67, and the string 67 is passed through the holder. The friction applied to the string 67 is such that the string 67 slides through the through hole when the string 67 is pulled up / down by hand, but the string 67 does not slide under the own weight of the mobile phone 6 when the string 67 is put on the ear. Is good. Therefore, when the part of the ring of the string 67 is hung on the ear and the string 67 on the holder 8 side is pulled down, the ear
And the head of the mobile phone 6 can be fixed stably, and it is possible to talk without any hand. If the mobile phone 6 is not provided with the string 67, the string 67 is prepared separately.

Another example of the holder 8 is shown in FIG.
The holder 8 has a simple structure in which the string 67 is held between its both arms, so that a required friction can be given to the string 67 which is thicker than the through hole. When the strings 67 are set in the holder 8, the strings 67 are passed one by one through the front groove. In addition, string 67
When you remove, the opposite is fine.

FIG. 8B shows a case where a band-type holder 9 is provided instead of the holder 8. The holder 9 has an appropriate elasticity (stretchability) like a rubber band, for example.
And has frictional properties on the surface, and preferably has transparency. After the holder 9 is fitted in a position where the function of the mobile phone 6 is not impaired, the holder 9 and the mobile phone 6 are inserted.
Pass the string 67 between them. The friction applied to the string 67 in this state is such that when the string 67 is pulled up / down by hand, the string 67 slides through the gap, but the string 67 does not slide under the own weight of the mobile phone 6 when the string 67 is put on the ear. Something of degree is good. Therefore, when the ring of the string 67 is hung on the ear and the string 67 on the holder 9 is pulled downward, the ear can be stably sandwiched between the string 67 and the head of the mobile phone 6 and the conversation can be performed without hands. Note that a configuration such as the holder 8/9 may be provided integrally on the main body side of the mobile phone 6 in advance.

Therefore, the user can freely move the face while hung on the ear. In FIG. 13A, both sides of the upper half 61a of the antenna 61 of this example are swelled right and left so that the antenna 61 can be easily put on the ear.

On the other hand, the length of the antenna line 61c (not shown) for actually transmitting / receiving a radio wave is preferably set to be substantially equal to the upper / lower half of the antenna 61a from the left / right substantial antenna support portion in order to increase the transmission / reception sensitivity of the radio wave. Near the right / left tip. Such an antenna 61 (antenna wire 61
The entirety of c) is covered with plastic, dielectric resin, or the like, so that the antenna wire 61c does not directly touch the user's skin.

In FIG. 13 (A), if the holder 2B 'becomes a substantial antenna support for supporting the antenna 61, the holder 2A' on the opposite side simply guides the antenna end. Guide function (for example, holes)
It may be a simple one having only The opposite is true when the holder 2A 'becomes a substantial antenna support.
