Description

  The present invention relates to an eyeglass frame in which temples are attached to embedded portions embedded on both sides of a resin-made front frame that holds the periphery of a lens via an elastic body.

  In general, a spectacle frame includes a full rim type as shown in Patent Document 1 and a half rim type. The temples that are in contact with the side portions of the user's head through the embedded portions are respectively attached to both sides of the back surface of the rim to which the left and right lenses are attached so as to be able to turn inward from a predetermined expanded state. It is possible.

  In the general spectacle frame configured as described above, the temple is turned from the both sides of the ear portion of the user's head in a state where it has been rotated outward and stopped at the maximum, that is, in a fully expanded state. It is used by the user, and the warp state of the temple is mainly adjusted according to the width of the user's head so that the user does not feel tight during use.

However, in the conventional spectacle frame as described above, an attempt is made to ensure the optimum state for the user mainly by adjusting the warp state of the temple, but the temple is integrated with the armor part. There is a problem that the adjustment of the temple affects the armor part attached to the rim.
Moreover, since the adjustment is performed mainly by adjusting the temple, the temple is bent without displacing the armor side of the temple, and a part of the inner surface of the temple is dotted on the user's head. The abutting force on the head increases, and there is a problem that the head may be painful.
JP 2003-43427 A (see FIG. 1)

In the present invention, the temple that can be folded inward from the predetermined expanded state is connected to the armor portion via the elastic body so that the entire temple can be displaced by the elastic body. One or both of the temples are expanded when they are removed, and the space between the temples is expanded, so that the wearing feeling is deteriorated, and it is possible to prevent the possibility of shifting or tilting when the temples are worn.
In addition, since the entire temple can be displaced by the elastic body, a part of the inner surface of the temple is not in contact with the user's head, but in contact with the surface of the user. It is an object of the present invention to provide a spectacle frame that reduces the feeling of wearing by causing a small contact force to act and eliminates the possibility of pain in the head.

  In the present invention, a temple that can be folded inward from a predetermined expanded state is connected to the other end of an elastic body, one end of which is fixed to the front frame, so that the entire temple can be displaced by the elastic body. Thus, a part of the inner surface of the temple is not in contact with the user's head, but is in contact with the surface so that a small contact force acts on the user's head. To eliminate the risk of pain in the head, and the insertion part of the nose pad assembly having the nose pad can be inserted into the recess provided in the front frame and can be screwed to facilitate assembly. An object of the present invention is to provide a spectacle frame.

In the present invention, a resin-made front frame for holding a lens, embedded portions embedded on both sides of the back surface of the front frame, and one end of each of the embedded portions are fixed and curved outward and inward. An S-shaped elastic body, and a core portion and a cover portion that covers the core portion, provided on the opposite side of the elastic body from the embedded portion, respectively, and a rear end portion of the cover portion; It adopts the means composed of temples that are modern. Then, the said elastic member and the temple of the core is mounted rotatably via a hinge, and prevented from rotating more than a predetermined, when clamping the head of the user is the elastic Adopted a means to displace the body.

In addition, the present invention is an S-shaped elastic member having one end fixed to a resin-made front frame for holding a lens and an embedded portion embedded on both sides of the back surface of the front frame and curved outward and inward. The body and the elastic body are provided on the opposite side of the embedded portion via hinges, and are formed of a core portion and a cover portion covering the core portion, and the rear end portion of the cover portion is modernized And a recess provided in the center of the rear surface of the front frame, an insertion portion provided in a nose pad assembly having a nose pad, and a means capable of being screwed in a state where the insertion portion is inserted into the recess. Is adopted. Then, the said elastic member and the temple of the core is mounted rotatably via a hinge, and prevented from rotating more than a predetermined, when clamping the head of the user is the elastic Adopted a means to displace the body.

In the spectacle frame of the present invention, one end is fixed to the resin-made front frame for holding the lens and the embedded portions embedded on both sides of the back surface of the front frame, and the central portion is curved inward. A pair of elastic bodies and a core part and a cover part covering the core part, each provided on a side opposite to the embedded part of the elastic body via a hinge, the rear end part of the cover part Since the temple is made up of modern temples, not only the temples are displaced during expansion, but the entire temple can be displaced by an elastic body, so one or both of the temples can be worn when wearing or removing glasses. The spread between the temples spreads and the feeling of wearing becomes worse, and it is possible to prevent the possibility of falling or tilting when hanging.
Further, since the entire temple can be displaced by the elastic body, a part of the inner surface of the temple does not abut against the user's head, but abuts in a planar shape. As a result, the contact force with respect to the user's head can be reduced to reduce the feeling of wearing, and the possibility of causing pain to the user's head during use can be eliminated.
Further, since the elastic body is fixed in a state where one end thereof is embedded in the front frame, the front frame and the elastic body are firmly integrated.
Further, the elastic body and so the temple and was prevented from rotating in a predetermined or higher with attached rotatably via a hinge, thus temples to the displacement of the elastic body during a predetermined further rotation There is no fear of causing pain in the user's head due to the spread itself.
Further, when the user's head is clamped, the elastic body is displaced and the temple is also displaced. Therefore, the contact force to the head may be small, and there is no possibility of causing pain to the user.
Further, since the elastic body has a shape in which the central portion is bent inward, the elastic body itself is hardly deformed even when the temple is greatly expanded.

Further, the insertion portion of the nose pad assembly having the nose pad can be inserted into the recess provided in the front frame and can be screwed to facilitate assembly.
Further, the elastic body and the temple are rotatably attached via a hinge and prevented from expanding beyond a predetermined level. There is no fear of causing pain on the user's head due to the spread. Therefore, when the user's head is clamped, the elastic body is displaced and the temple is also displaced, so that the contact force of the head can be small and there is no possibility of causing pain to the user.

Embodiments of the present invention shown in the drawings will be described below.
FIG. 1 shows a schematic plan view of a spectacle frame 1 according to the present invention, FIG. 2 shows a schematic front view, FIG. 3 shows a schematic view seen obliquely from above, and FIG. FIG. 4 (a) is a schematic diagram showing an expanded state, and FIG. 4 (b) is a schematic diagram showing a slightly folded state. 5 is a schematic detailed view showing a connected state of the front frame, the elastic body, and the temple, and FIG. 6 is a schematic view showing a connected state of the front frame and the nose pad assembly.

  The spectacle frame 1 is a resin-made full rim type, to which a pair of left and right lenses 2 and 2 are attached and a front frame 3 provided with a bridge portion 4 in the center, and both of the back surfaces of the front frame 3. The elastic bodies 5 and 5 provided at the outer ends, and the elastic bodies 5 and 5 are provided on the opposite side of the front frame 3 via hinges 6 so as to cover the upper part of the ear portion of the user's head. The temples 7 and 7 are provided so as to press and hold the part.

  The elastic bodies 5, 5 provided on both sides of the front frame 3 have embedded portions 8, 8 provided at one end thereof embedded in the outer end portion of the front frame 3, so that both outer ends of the front frame 3 are provided. It is fixed to the part. Further, both elastic bodies 5 and 5 are formed so as to have a large elasticity because their central portions are curved inwardly in an inverted U shape.

  Temples 7, 7 provided at the other ends of the elastic bodies 5, 5 through hinges 6, 6 are composed of a core part 9 and a cover part 10 covering the core part 9. The ends of the elastic bodies 5 and 5 and the cores 9 and 9 are connected by hinges 6 and 6. The temples 7 and 7 are formed such that the cover portions 10 and 10 constituting the temples 7 and 7 function as moderns 11 and 11 at the end opposite to the elastic bodies 5 and 5.

  Accordingly, the hinges 6 and 6 allow the temples 7 and 7 to be folded between the maximum opened position shown in the figure and the position folded inward from this position.

  The nose pad assembly 12 has a bowl shape, pads 14 and 14 are attached to both sides via legs 13 and 13, and an insertion portion 15 is provided at the center. On the other hand, a concave portion 16 is formed in the center of the back surface of the bridge portion 4 of the front frame 3, and the insertion portion 15 of the nose pad assembly 12 can be inserted into the concave portion 16. The front frame 3 and the nose pad assembly 12 are fixed by a screw that is screwed into a screw hole 18 provided in the insertion portion 15 through a hole 17 penetrating into the recess 16 of the frame 3 from below. .

In the spectacle frame 1 configured as described above, first, the temples 7 and 7 are opened from the folded state so that the user can use them.
Then, the user inserts a head between the temples 7 and 7 in order to start use, that is, the temples 7 and 7 hold the upper part between both ears of the user's head.

  When the two temples 7 and 7 are expanded at the time of clamping, the temples 7 and 7 are not only expanded with the hinges 6 and 6 as fulcrums, but are also connected to the hinges 6 and 6 and elastically curved inwardly. The bodies 5 and 5 are displaced.

  That is, by making the space between the two temples 7 and 7 in the expanded state narrower than the head, the other end portion is pushed and spread with the embedded portions 8 and 8 of the elastic bodies 5 and 5 as fulcrums, The combination of the elastic deformation and the slight displacement of the resin front frame 3 causes the temples 7 and 7 themselves to contact the user's head in a planar shape.

  Therefore, unlike the case of a general eyeglass frame, a part of the temples 7 and 7 is in contact with the head, and a large force is applied to the head of the part to feel a strong wearing feeling. Since the temples 7 and 7 come into contact with the surface and a small force acts on the head of the portion, the user does not feel a strong wearing feeling even when used for a long time. In addition, since the user's head is securely held, there is no possibility of shifting or dropping during use.

  FIG. 6 shows a nose pad assembly 12 attached to the back side of the bridge portion 4 of the front frame 3. A horizontally elongated recess 16 is provided on the back side of the bridge portion 4 of the front frame 3, and a hole 17 penetrating into the recess 16 is formed below the bridge portion 4. On the other hand, the insertion portion 15 of the nose pad assembly 12 can be inserted into the recess 16 and a screw hole 18 is formed at a position corresponding to the hole 17 at the time of insertion.

Accordingly, when the insertion portion 15 of the nose pad assembly 12 is inserted into the recess 16 of the front frame 3 and a screw is inserted into the hole 17 from below and then screwed into the screw hole 18 of the insertion portion 15, On the other hand, the nose pad assembly 12 is fixed.
As a result, as in the case of the above-described embodiment, a part of the temples 7 and 7 is in contact with the head as in the case of a general eyeglass frame, and a large force is applied to the head of the part, so that the user is strong. Unlike the feeling of wearing, the temples 7 and 7 come into contact with the surface and a small force acts on the head of the part, so that the user feels a strong wearing feeling even if used for a long time. There is no. In addition, since the user's head is securely clamped, there is no risk of shifting or dropping during use, and attachment of the nose pad assembly 12 to the front frame 3 is very simple.
Even in the temples 7, 7 configured as described above, the further expansion after the maximum expansion is performed in the same manner as in the above-described embodiment, the embedded portion 8 (connection) in which the elastic bodies 5, 5 are fixed to the front frame 3. Part) is expanded by using the fulcrum as a fulcrum, and comes into contact with the upper part of the user's ear in a planar shape, and there is no fear of causing pain to the user.

  In the above-described embodiment, the full rim type spectacle frame is shown. However, the present invention is not limited thereto, and may be a half rim type. By adopting the temples 7 and 7 connected to the hinge 5 through the hinges 6 and 6, it is brought into contact with the user's head in a planar shape and securely clamped with a small acting force. Therefore, even when the user uses the device for a long time, there is no fear of feeling painful.
