FIG. 5 illustrates a problem that occurs when a spectacle wearer wearing spectacles having temples 11 and 11 on both ends of a front frame 14 holding a lens wears a device or instrument having an ear pad P such as headphones. It is a figure to do. When a device such as headphones is worn on the head after wearing glasses, the temples 11, 11 of the glasses-shaped frame are pressed by the ear pad portion P (the pressing direction is indicated by an arrow in the figure). In addition to the problem that 11 causes pressure on the temporal region of a spectacle wearer such as a game player and causes discomfort, there is a gap between the ear pad portion P and the head at the portion where the temples 11 and 11 are inserted. This causes problems such as sound leakage, noise, and outside air.
The headphones set in the glasses described in Patent Document 1 are made to eliminate the discomfort caused by the interference between the glasses and the headphones, and the headphones are fixed to the temples of the glasses. In addition, the headphone device with glasses for stereoscopic image observation described in Patent Document 2 provides a headphone device that is not troublesome even after long-term use, and the glasses for stereoscopic image observation are rotatably attached to the headphones. .
However, in both Patent Documents 1 and 2, there is a problem that dedicated headphones are required or headphones that can be used are limited, and it is desirable to use headphones separately for game players that are concerned with sound quality and music and games. There is a problem that it is unsuitable for users who wish.

  The present invention has been made in view of such a problem. Even if a wearer of a spectacle-shaped frame such as a game player wears an instrument or device having an ear pad such as a headphone on the head, the spectacles are worn. Without any discomfort or discomfort to the person, and when a device or device such as headphones is worn on the head, it is difficult to create a gap between the ear pad and the head of the eyeglass wearer. such as earmuffs not limited to headphones, an object of widespread provision of spectacle-type frame which can correspond to an instrument or apparatus having other ear portion.

The spectacle-shaped frame of the present invention, as described in claim 1, is configured to prevent the ear rest and the temple from interfering with each other when an instrument or device having an ear rest such as a headphone is attached to the head. In the shape frame, the temple includes a main temple having an ear hook portion, an auxiliary temple provided adjacent to the main temple, and a temple unfolding mechanism provided at a base portion of the main temple and the auxiliary temple. The unfolding mechanism is configured to rotate at least the main temple to an upper position where the base portion does not interfere with the ear pad portion.
Since the present invention is configured as described above, it is used as a normal spectacle frame with the main temple and the auxiliary temple closed in a state where an instrument or device having an ear pad such as headphones is not worn on the head. be able to. When wearing a device or instrument such as headphones, the main temple can be rotated to a position where it does not interfere with the ear pads such as headphones, so that the temple is pressed by the ear pads and the glasses wearer feels uncomfortable. There is no discomfort. Further, there is no gap between the ear pad and the eyeglass wearer's head. According to a second aspect of the present invention, the auxiliary temple is rotated to a position where it comes into contact with the face of the spectacle wearer so that the main temple is turned upward, and then the eyeglass-shaped frame is moved by the auxiliary temple that comes into contact with the face. It can support and can suppress the fall of a spectacles frame.

According to a third aspect of the present invention, the temple unfolding mechanism may be provided at the end portion of the front frame. According to a fourth aspect of the present invention, the shape of the main temple may be a straight shape up to the ear hook, and the rear end portion may be formed in a curved shape so as to go around the back of the head of the spectacle wearer. If it does in this way, the length of a main temple can be ensured more than fixed, and the rotation angle of a main temple can be made small.
The standard of the rotation angle to prevent the temple in the general spectacle frame from interfering with the ear rest used in a general device or instrument is 25 ° to the main temple as described in claim 5. It is about 35 °. In the auxiliary temple, it is about 35 ° to 45 °. As described in claim 6, by changing the rotation angle of the main temple and the auxiliary temple, the main temple and the auxiliary temple according to the size of the ear pad or the shape of the face of the spectacle wearer. It becomes possible to select an appropriate rotation angle of the auxiliary temple.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.

It is a bottom view of 1 spectacles type frame.

  The spectacle frame generally includes a front frame that holds a lens, and a temple that is attached to the left and right sides of the front frame and has an ear hook portion that hangs on the ear of the spectacle wearer. Also, a nose pad is generally provided between the left and right lenses so that the front frame does not slide down. Also, to be able to fold the temple during non-wearing, the front frame and the left and right temples are connected by a hinge.

The eyeglass-shaped frame 1 of this embodiment has a front frame 14 that holds the left and right lenses L, L, and a temple 11 that can be folded by hinges 13 provided at both ends of the front frame 14. The temple 11 has a main temple 11a extending from the hinge 13 through the ears of the spectacle wearer to the back of the head and a short auxiliary temple 11b disposed below the main temple 11a.
The main temple 11 a and the auxiliary temple 11 b can be expanded up and down by a temple expansion mechanism 12 provided behind the hinge 13.
FIG. 1B and FIG. 2B show a state after the main temple 11a and the auxiliary temple 11b are unfolded.
The base portions of the main temple 11a and the auxiliary temple 11b are rotatably supported by the temple unfolding mechanism 12. The main temple 11a is rotatable about a support shaft (not shown) provided on the temple unfolding mechanism 12 from a horizontal position to an upper position where it does not interfere with the ear pad 2. The auxiliary temple 11b uses the support shaft as a fulcrum. It can be rotated from a horizontal position to a lower position where it comes into contact with the face of the spectacle wearer. The main temple 11a preferably has a shape extending substantially straight from the base to the ear hook so as not to interfere with the ear pad 2 even after rotation. Further, it is preferable that the rear end portion of the main temple 11a has a curved shape that goes around to the back of the head of the spectacle wearer so that the spectacle-shaped frame 1 is not displaced forward when the spectacles are worn.

  By making the main temple 11a straight and providing the temple unfolding mechanism 2 as close to the front frame 14 as possible, the length of the main temple 11a can be sufficiently secured, and the rotation angle of the main temple 11a θa can be reduced. The rotation angle θa of the main temple 11a can be about 25 ° to 35 ° as a guide. Further, the auxiliary temple 11b is brought into contact with the face of the spectacle wearer after deployment, thereby suppressing the shift of the spectacle frame 1 after the main temple 1a is rotated upward. The rotation angle θb of the auxiliary temple 11b can be approximately 35 ° to 45 ° as a guide.

  As the temple unfolding mechanism 12, a known mechanism can be used as long as it can be unfolded by rotating the main temple 11a and the auxiliary temple 11b upward and downward, respectively. The temple unfolding mechanism 12 includes a lock mechanism for locking the main temple 11a and the auxiliary temple 11b in a horizontal position, a lock release button 12a for releasing the lock by the lock mechanism, and the main temple 11a and the auxiliary temple 11b when the lock is released.
