This is a U.S. national phase application under 35 U.S.C. § 371 of International Patent Application No. PCT/JP2005/003294, filed Feb. 28, 2005. The International Application was published in Japanese on Sep. 8, 2006 as International Publication No. WO 2006/092831 under PCT Article 21(2), the content of which is incorporated herein in its entirety.
TECHNICAL FIELDThe present invention relates to a holder that uses a person's ear to hold an article having comparatively small mass, such as a portable phone or a compact camera.
BACKGROUND ARTIn the past, many methods have been used wherein a person's ears are used to attach small tools and the like necessary to human social life. Typical examples include eyeglasses and hearing aids. Eyeglasses are a tool for correcting vision, and are designed to be attached using the ears and the nose. A hearing aid is a tool used to assist the hearing capacity of the hearing-impaired, and this tool relates to the ear and is therefore designed to be attached using the ear.
Other typical examples of objects attached to a person's ear include earphones for portable radios or portable stereos. There are various types of earphones, but broadly classified, there are those wherein the earphone main body is simply inserted into the external ear canal, and those provided with an attachment outside of the external ear canal. Earphones wherein the earphone main body is simply inserted into the external ear canal have had problems wherein the attachment is incomplete and the earphone easily falls out. As a countermeasure for dealing with this problem, there are headphones wherein an arm is placed over the head, and speakers are attached to both ears. Aside from headphones, there have been no few proposals pertaining to holders for reliably holding earphones or the like without the earphones falling out of the ears (for example, see Japanese Laid-open Patent Application No. 2002-58086 and Domestic Republication No. 2003-511940).
There have not been holders that use the ear to hold compact cameras and the like, which are devices not directly related to the ear. The present inventors, at least, are unaware of any such holders.
SUMMARY OF THE INVENTIONHowever, the inventions disclosed in the Patent Documents above are both devices for holding earphones or hearing aids, which are tools relating to the ear, and are not intended to hold compact cameras or other such devices that do not relate to the ear. Therefore, it has not been possible to hold compact cameras or the like, which have greater mass than earphones and the like, and which require a greater holding force than cases in which earphones or the like are held. It is possible to hold a certain external load by hanging a cord between a person's head and external ear, but since the external ear is merely cartilage and easily deformed, a reliable hold cannot be expected. Furthermore, headphones can be held reliably only if the speakers are secured, and an arm must be placed over the head for that, resulting in a problem in which the hair is affected and the headphones are dull in appearance and unattractive.
The present invention was designed in view of these circumstances, and an object thereof is to provide a holder capable of using the external ear canal or the external ear to hold a comparatively large external load.
In the holder of aspect 1 in the present invention, a plurality of protrusions is provided at one end of a holding arm, one of the protrusions is inserted into a first curve in an external ear canal, and a load can be held on the other end of the holding arm.
In the holder of aspect 2 in the present invention, a protrusion supporter including a plurality of protrusions is attached in a hole formed in one end of the holder, one of the protrusions is inserted into a first curve in an external ear canal, and a load can be held on the other end of the holding arm.
In the holder of aspect 3 in the present invention, the position and angle of at least one of the protrusions can be arbitrarily adjusted.
The holder of aspect 4 in the present invention is the invention of aspect 2, wherein the positions and angles of the protrusions provided to the protrusion supporter are adjusted by tightening a mounting screw of the protrusion supporter.
The holder of aspect 5 in the present invention is the invention of any of aspects 1 through 4, wherein an opening is formed in one of the protrusions.
The holder of aspect 6 in the present invention is the invention of any of aspects 1 through 5, wherein the protrusions are made from a flexible material.
In the holder of aspect 7 in the present invention, a bent attachment is provided at one end of a holding arm in place of the protrusions, the distal end of the attachment is inserted into a first curve in an external ear canal, and a load can be held on the other end of the holding arm.
The holder of aspect 8 in the present invention is the invention of aspect 7, wherein a moving mechanism is provided at the distal end of the attachment, the distal end is inserted into the external ear canal cavity, and the distal end is then bent.
The holder of aspect 9 in the present invention is the invention of aspect 7 or 8, wherein an opening is formed in the distal end of the attachment.
The holder of aspect 10 in the present invention is the invention of aspect 1, 2, or any of aspects 7 through 9, wherein the holding arm is attached between the helix and the side of the head.
The holder of aspect 11 in the present invention is the holder of any of aspects 7 through 10, wherein the distal end of the attachment is made from a flexible material.
The holder of aspect 12 in the present invention is the invention of any of aspects 1 through 11, wherein a rear arm that encloses the external ear is mounted on the other end of the holding arm.
The holder of aspect 13 in the present invention is the invention of aspect 12, wherein the other end of the holding arm and the rear arm are supported to be capable of rotating by a specific angle, and a spring is attached between the holding arm and the rear arm.
In the holder of aspect 14 in the present invention, the holding arm and the rear arm are integrally molded from a flexible material, and the rear arm is capable of rotating by a specific angle in relation to the holding arm due to the return force of the flexible material.
The holder of aspect 15 in the present invention is the invention of any of aspects 1 through 14, wherein the holding arm is made from a hollow member, and sounds from a speaker are transmitted to the external ear canal through a hollow part in the holding arm.
The holder of aspect 16 in the present invention is the invention of any of aspects 12 through 15, wherein a speaker is housed inside the member of the rear arm.
The holder of aspect 17 in the present invention is the invention of any of aspects 12 through 15, wherein a speaker is attached to the other end of the holding arm.
The holder of aspect 18 in the present invention is the invention of aspect 13, wherein a moving mechanism is provided inside the rear arm, and a helix back plate is operated by the moving mechanism.
According to the holder of aspect 1 in the present invention, since one end of the holder is reliably attached in the first curve of the external ear canal, it is possible to hold an article of comparatively large mass. It is also possible to obtain a highly stable holder wherein there is no danger of part of the holder sticking into the skull even when the holder overturns while still attached in the ear.
According to the holder of aspect 2 in the present invention, it is possible to obtain a holder wherein the positions and angles of the protrusions can be adjusted to an extent.
According to the holder of aspect 3 in the present invention, it is possible to obtain a holder that can easily be adapted to individual differences in the shapes and sizes of different external ear canals. Therefore, it is possible to obtain a holder that is excellent for the ear, wherein not even part of the external ear canal is locally compressed.
According to the holder of aspect 4 in the present invention, the positions and angles of the protrusions can be adjusted easily and efficiently.
According to the holder of aspect 5 in the present invention, since the external ear canal is not closed off when the holder is attached to the ear, auditory perception of the surrounding environment necessary to daily life is not hindered. Therefore, it is possible to operate a vehicle, for example, because sounds necessary to daily life can be perceived while wearing the holder in the ear. Since the protrusion having the opening has low resistance to deformation, the protrusion adapts to the shape of the external ear canal relatively easily, and it is therefore possible to obtain a holder that fits well in a wide range of external ear canals having individual differences. Furthermore, since the external ear canal is not closed off, there is no change in pressure in the external ear canal when the holder is attached or removed. Therefore, it is possible to prevent accidents in which the eardrum is damaged by sudden pressure changes.
According to the holder of aspect 6 in the present invention, the external ear canal is not damaged, because the protrusions deform due to the flexibility of the protrusions even with different shapes or sizes in external ear canals having individual differences.
According to the holder of aspect 7 in the present invention, it is possible to obtain a holder that is easily manufactured and has low manufacturing costs.
According to the holder of aspect 8 in the present invention, since a moving mechanism is provided at the distal end of the attachment, the distal end is inserted into the external ear canal cavity, and the distal end can then be bent, the distal end is easily inserted into the external ear canal.
According to the holder of aspect 9 in the present invention, since the external ear canal is not closed off when the holder is attached to the ear, auditory perception of the surrounding environment necessary to daily life is not hindered.
According to the holder of aspect 10 in the present invention, since the holding arm is attached between the helix and the side of the head, it is possible to hold a comparatively large mass.
According to the holder of aspect 11 in the present invention, since the distal end of the attachment easily deforms, the external ear canal is not damaged even if the shapes and sizes of external ear canals are different due to individual differences.
According to the holder of aspect 12 in the present invention, since the external ear is enclosed by the holding arm and the rear arm, it is possible to obtain a holder that does not easily come loose even when the head is moved or tilted. It is also possible to obtain a holder that does not easily come loose in cases in which a certain amount of unnecessary force is applied from the exterior, because the degree of freedom in all of six directions can be limited.
According to the holder of aspect 13 in the present invention, it is possible to obtain a holder that is even less likely to come loose, because the external ear is held between the holding arm and the rear arm by the urging force of the spring.
According to the holder of aspect 14 in the present invention, since the external ear is enclosed between the holding arm and the rear arm by the return force of the flexible material, it is possible to obtain a holder that does not easily come loose.
According to the holder of aspects 15 and 16 in the present invention, an article can be held by the ear, and music or the like can be enjoyed individually in the same manner as with an earphone. The speaker can also be kept in a location separate from the ear, i.e., in a clothing pocket.
According to the holder of aspect 17 in the present invention, sound from the speaker can easily be transmitted to the external ear canal and blocked.
According to the holder of aspect 18 in the present invention, the entire holder can be reliably fixed in place on the ear, and an external load can be held stably and reliably.
Modes for carrying out the present invention are described hereinbelow with reference to the diagrams.
Example 1Of the two protrusions 12, 13 provided to one end of the holding arm 11, the other protrusion, which is a restraining protrusion 13, rests in contact with the side surface of the cavity of concha, which is equivalent to the entrance of the external ear canal. This protrusion 13 is substantially the same size as the distal protrusion 12. The hole 14 provided at the other end of the holding arm 11 is an attachment hole for holding an external load, and a portable phone or portable radio or the like can be suspended from this hole by means of a cord or the like. The hole 14 is provided in the present example, but another possibility is to form a hook instead of the hole 14 and to hold an external load by means of the hook.
Next, the method for inserting the holder 10 into the external ear canal in the present example will be described. Knowledge of the structure of the human ear is required as a necessary condition, and a simple description of the structure of the human ear will therefore be given with reference to
According to the holder 10 of the present example, since one end of the holder 10 is reliably attached to the first curve 17 of the external ear canal, an article of comparatively large mass can be held. The restraining protrusion 13 restricts the holding arm 11 from being inserted into the external ear canal 16 in cases in which the holder 10 overturns while still attached to the ear, and it is therefore possible to obtain a highly stable holder 10 wherein there is no danger of the distal end of the holder 10 reaching the eardrum.
Example 2Since the distal protrusion 22 having the loop-shaped opening 24 has little resistance to deformation, the distal protrusion 22 easily deforms in accordance with the shape of the external ear canal 16, and it is therefore possible to obtain a holder 20 whereby a good fit is provided within a wide range with external ear canals 16 that differ from each other. Furthermore, since the external ear canal 16 is not closed off, the pressure inside the external ear canal 16 does not change when the holder is attached or removed. Therefore, it is possible to prevent accidents in which the eardrum is damaged by sudden pressure changes.
Example 3However, the shapes of people's ears have individual differences, and the size and shape of the external ear canal 16 varies greatly with the individual. Therefore, although two protrusions 52, 53 are provided at one end of the holding arm 51, if the positions and angles of these protrusions 52, 53 cannot be adjusted, it is difficult to adapt to the shape of the external ear canal 16 on the basis of the individual differences. Therefore, there is a great need to bring the positions and angles of the two protrusions 52, 53 in alignment with the wearer of the holder.
The following is a simple description of the method for attaching the protrusions 52, 53 to the protrusion supporter 55 and mounting the tool on the holding arm 51. In the state shown in (a) in the diagram, the hole 53a formed in the restraining protrusion 53 is fitted at a right angle to the threaded shaft 56 over the portion where the fixing piece 56a and the movable piece 56b are fastened together. The distal protrusion 52 is then attached to the portion of the fixing piece 56a and the movable piece 56b oriented at an upward incline, but the fixing piece 56a and the movable piece 56b are inserted into a hole 52a in the distal protrusion 52 while being made to coincide with each other. Therefore, in this state, the right surface of the movable piece 56b is displaced to the right of the right surface of the fixing piece 56a. Specifically, the distal protrusion 52 is merely inserted into the protrusion supporter 55, and is not quite firmly fixed in place. Next, in this state, the threaded shaft 56 of the protrusion supporter 55 is inserted into the hole 51b formed in the small shaft 51a of the holding arm 51, and the nut 57 is then used to fix the protrusion supporter 55 in place on the holding arm 51. Thus, the right surface of the fixing piece 56a and the right surface of the movable piece 56b, which have not coincided, are then made to coincide by an end surface 51c of the small shaft 51a of the holding arm 51. Specifically, the top of the fixing piece 56a and the top of the movable piece 56b that are inserted into the mounting hole 52a in the distal protrusion 52 are brought from the coinciding state in a front view to a slightly open state as shown in (a). Strong surface pressure can thereby be applied to the inner surface of the mounting hole 52a in the distal protrusion 52, fixing the protrusion supporter 55 in place with the distal protrusion 52. When the angles and positions of the distal protrusion 52 and restraining protrusion 53 are varied, they can be easily adjusted a second time by re-fastening the nut 57 after optimizing the angles and positions by loosening the nut 57 on the threaded shaft 56 that fixes the protrusion supporter 55 to the holding arm 51.
Furthermore, the two protrusions 52, 53 are made not from a highly rigid material such as metal or plastic, but rather from a flexible resin material. If this type of soft resin material is used, the flexibility of the resin material allows the protrusions 52, 53 to adapt to the shape of the middle ear canal 16 when the shape of the protrusions 52, 53 and the shape of the middle ear canal 16 are somewhat incompatible. Various rubber materials can be used in cases in which even greater flexibility is required. In this case, the attaching function of the protrusions may be compromised when the protrusions are made solely from a rubber material. To prevent this, a rubber material can be used for the protrusions 52, 53, and stainless steel, cupronickel, or another such metal material can be used for core members 56a, 56b of the protrusions, as shown in
A protrusion having an opening 54 whose overall shape is a loop is used for the distal protrusion 52 shown in the present example, but a distal protrusion 52 that does not have an opening can also be used in cases in which auditory perception of the surrounding environment can be sacrificed.
With this configuration, when the operating lever 68 rotates around the shaft 66, the rotational motion of the link 67 is converted to a reciprocating motion in the coupling rod 65, and the reciprocating motion of the coupling rod 65 creates rotational displacement in the distal protrusion 62. Therefore, the angle of the distal protrusion 62 can be varied by moving the operating lever 68. When the distal protrusion 62 is inserted into the external ear canal 16, the operating lever 68 can thereby be operated to bring the positions of the distal protrusion 62 and the horizontal arm member 63 nearly parallel, allowing easy insertion into the external ear canal 16. When the operating lever 68 is returned to its original position after the distal protrusion 62 has reached a specific position, the angle formed by the distal protrusion 62 and the horizontal arm member 63 returns to its initial position, and the distal protrusion 62 can be attached in the first curve 17 of the external ear canal.
Example 7With the holder 80 of the present example, since the external ear is enclosed by the holding arm 81 and the rear arm 84, it is possible to obtain a holder 80 that does not easily come loose when the head is moved or tilted. The degree of freedom in all of six directions can also be limited in cases in which a certain amount of unnecessary force is applied from the exterior.
Example 9The present invention has industrial applicability as a holder that uses a person's ear to hold a portable phone, a compact camera, or another such external load.
