Description

Technical Field

[0001] The present invention relates to eyewear such as sunglasses and glasses.

Background Art

[0002] There is eyewear in which a lens part is detachable from a frame part (for example, Patent Document 1). In the eyewear described in Patent Document 1, levers that can move open and closed with respect to a front frame are provided at both left and right ends of the front frame. And magnets are provided on each of the front frame and the lever. The magnets are arranged to attract each other.

[0003] By positioning the lens part so as to be sandwiched between the front frame and the lever in the closed state, the magnets provided on each of the front frame and the lever attract each other with the lens part sandwiched therebetween. Thereby, the lens part is held between the front frame and the lever.

[0004] However, there are several points to be improved in the above configuration. First, since the lens part is held only by magnetic force, for example, when an impact is applied to the eyewear, the lens part is likely to fall off from the front frame. Next, when attaching the lens part to the front frame, it is necessary to close the lever parts provided at both ends of the front frame. Similarly, when removing the lens part from the front frame, it is necessary to open the lever parts. For this reason, the attachment and detachment of the lens part is troublesome.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Therefore, an object of the present invention is to provide eyewear that can surely prevent the lens part from falling off when worn by the user and facilitates the attachment and detachment of the lens part when not worn.

Means for Solving the Problems

[0007] The present invention includes a front frame having a connection part, a temple that is connected to the front frame so as to be openable and closable, a light-transmitting part that transmits light, and a connected part that is connected to the connection part when attached to the front frame, and a lens part that is detachably provided on the front frame, and an engaging part that is provided on the temple and moves closer to and away from the front frame in conjunction with the opening and closing operation of the temple and can engage with the lens part.

[0008] According to this configuration, in addition to the connection between the connection part of the front frame and the connected part of the lens part, the engaging part of the temple engages with the lens part. Therefore, since the lens part is held by both the front frame and the temple, it is possible to make it difficult for the lens part to fall off from the front frame. Further, because the engaging part is configured to be interlocked with the opening and closing operation of the temple, for example, when the temple is opened during wearing, the engaging part can be engaged with the lens part accordingly, so that an operation for engagement only is not required.

[0009] Further, the engaging part can be provided at one end of the temple on the front frame side.

[0010] According to this configuration, since a part of the temple can be the engaging part, the engaging part that moves closer to and away from the front frame can be easily configured.

[0011] Further, the engaging part can engage with the lens part in a state where the temple is open.

[0012] According to this configuration, since engagement with the lens part can be achieved as the temple opens, the engaging part functions during wearing by the user, so that suppression of the lens part from falling off can be surely achieved.

[0013] Further, when the lens unit is attached to the front frame and the engaging portion is engaged with the lens unit, at least a part of the connected portion and the engaging portion overlap in a front view of the lens unit. It can be such a thing.

[0014] According to this configuration, since a part of the connected portion and the engaging portion overlap in a front view, the connection between the connecting portion and the connected portion and the engagement between the engaging portion and the lens unit are made at the same position. Therefore, the engaging portion can assist the connection state between the connecting portion and the connected portion.

[0015] Further, the lens unit can be located in front of the front frame, and the engaging portion can be provided so as to press the connected portion against the front frame in a state of being engaged with the lens unit.

[0016] According to this configuration, since pressing is further performed in addition to the engagement, the connection can be made more reliably.

[0017] Further, it can have a magnet provided on either one of the connecting portion and the connected portion, and a magnetic body to which the magnet provided on the other is magnetically attached.

[0018] According to this configuration, due to the combination of the magnet and the magnetic body, the connection is made by magnetic force. Therefore, while the light-transmitting portion and the frame can be easily attached and detached, the engaging portion can surely prevent the light-transmitting portion from falling off.

[0019] Further, the lens unit can be configured such that the left eye portion and the right eye portion are integrally provided.

[0020] According to this configuration, since the left and right can be attached and detached together, the attachment and detachment of the lens unit are easy.

Effects of the Invention

[0021] According to the present invention, it is possible to make the lens part difficult to fall off from the front frame, and no special operation for engagement is required. Therefore, it is possible to surely prevent the lens part from falling off when the user wears it, and to provide eyewear that facilitates attachment and detachment of the lens part when not in use.

Mode for Carrying Out the Invention

[0023] Next, sunglasses 1 as eyewear according to an embodiment of the present invention will be taken up and described. In addition, the expressions of front-back and up-down in the following correspond to the directions in the state shown in FIG. 1. Also, the side far from the user's face when worn is taken as the front, and the side close to the user's face is taken as the back. Further, the direction corresponding to the user's right eye side is taken as the right, and the direction corresponding to the left eye side is taken as the left.

[0024] As shown in Fig. 1, the sunglasses 1 of the present embodiment include a frame portion 2 and a lens portion 3 formed separately from the frame portion 2. As shown in Fig. 2, the frame portion 2 includes a front frame 4 positioned in front of the user's face when worn, and a pair of temples 5, 5 that are continuous with the left and right ends of the front frame 4 and are hung on the user's ears when worn. The front frame 4 has a connecting portion 41. This connecting portion 41 is connected to a connected portion 33 (see Fig. 3) provided on the lens portion 3. Thereby, the frame portion 2 and the lens portion 3 are integrated as shown in Fig. 1. The connection in the present embodiment is made by magnetic force. Therefore, the connecting portion 41 in the present embodiment is a portion in the front frame 4 where a magnetic metal, which is a magnetic body 411, is embedded.

[0025] The front frame 4 and each temple 5 are rotatably connected by a hinge 6 (see Fig. 4 etc.). Thereby, the temple 5 rotates with respect to the front frame 4. And by this rotation, the temple 5 is connected to the front frame 4 so as to be openable and closable. Fig. 1 shows a completely open state. The left and right parts of the pair of temples 5, 5 rotate around the hinge 6 so as to overlap each other, and enter a closed state (not shown). The temple 5 has an engaging portion 51 for preventing the lens portion 3 from falling off the frame portion 2. The engaging portion 51 will be described later.

[0026] The lens portion 3 is a detachable part with respect to the front frame 4 and is positioned in front of the front frame 4 as shown in Fig. 1 when worn. Here, the "detachable" means that it is realized by the connection by magnetic force etc. in the present embodiment and is in a state where it can be detached by the user's hand, and does not include a configuration that cannot be detached without using tools such as screwing.

[0027] As shown in FIG. 3, the lens unit 3 includes a light-transmitting portion (lens) 31 that transmits light in the thickness direction, a nose pad 32, and a connected portion 33 that is connected to the connecting portion 41 of the front frame 4 when the lens unit 3 is attached to the front frame 4. The connected portion 33 includes a magnet (permanent magnet) 331 and a frame-shaped magnet holding portion 332 in which the magnet 331 is embedded. In the present embodiment, the magnet 331 and the magnet holding portion 332 are integrally formed and inseparable. The magnet holding portion 332 is fixed to the left and right rear surfaces of the light-transmitting portion 31 by adhesion or the like. Due to the combination of the magnet 331 included in the lens unit 3 and the magnetic body 411 included in the frame portion 2, the lens unit 3 and the front frame 4 are connected by magnetic force. Therefore, when attaching the lens unit 3, the user only needs to align the lens unit 3 with the front frame 4. Thus, it is easy for the user to attach and detach the lens unit 3 from the front frame 4 by hand. In addition, in the lens unit 3 of the present embodiment, the left-eye portion and the right-eye portion are integrally provided. Therefore, the lens unit 3 can be easily attached to and detached from the front frame 4 integrally.

[0028] Note that the magnet 331 may be provided on either one of the connecting portion 41 and the connected portion 33 (in the present embodiment, the connected portion 33), and the magnetic body 411 to which the magnet 331 is magnetically attached may be provided on the other of the connecting portion 41 and the connected portion 33 (in the present embodiment, the connecting portion 41). Further, instead of the combination of the magnet 331 and the magnetic body 411, a pair of magnets with opposite polarities facing each other may be used.

[0029] In the sunglasses 1 of the present embodiment, the light-transmitting portion 31 is formed of a colored light-transmitting material (specifically, a resin plate). The light-transmitting portion 31 may be prescription (eyeglasses) or non-prescription (sunglasses, etc.). The light-transmitting portion 31 may be transparent. Further, the light-transmitting portion 31 may be formed by one or more slits or holes penetrating in the thickness direction in an opaque plate. The light-transmitting portion 31 may also be in a net shape.

[0030] The engaging portion 51 is provided on the temple 5. Specifically, the engaging portion 51 is integrally provided at one end of the temple 5 on the front frame 4 side. By configuring in this way, the engaging portion 51 that approaches and separates from the front frame 4 can be easily configured. Specifically, the engaging portion 51 has a claw portion 511 formed by squeezing one end of the temple 5 as shown in FIG. 5. This claw portion 511 is in a form in which the transverse dimension of the temple 5 is reduced, and is a plate-like portion formed offset to either the left or right side at one end of the temple 5. In the present embodiment, as shown in FIG. 5, an upper surface portion 52 that protrudes upward is formed together with the claw portion 511 at one end of the temple 5, and this upper surface portion 52 is also integrally provided at one end of the temple 5, but the upper surface portion 52 may not be provided.

[0031] The engaging portion 51 (specifically, the claw portion 511) approaches and separates from the front frame 4 in conjunction with the opening and closing operation of the temple 5 by rotating about the hinge 6 of the temple 5. When the temple 5 approaches the front frame 4, it can engage with the lens portion 3 located in front of the front frame 4. More specifically, the engaging portion 51 engages with the lens portion 3 in a state where the temple 5 is open (specifically, the fully open state shown in FIGS. 1 and 6). The engaging portion 51 engages along the side edge 3321 (see FIG. 3) which is a part of the magnet holding portion 332 in the lens portion 3. The engaging portion 51 engages so as to cover the magnet holding portion 332 from the front. Since the engaging portion 51 is configured in this way, it is possible to engage with the lens portion 3 as the temple 5 opens, so that it is possible to surely prevent the lens portion 3 from falling off from the frame portion 2 (front frame 4) of the lens portion 3.

[0032] When the lens portion 3 is attached to the front frame 4 and the engaging portion 51 in the temple 5 is engaged with the lens portion 3, the connected portion 33 and the engaging portion 51 in the lens portion 3 are in a state where at least a part overlaps in the front view of the lens portion 3 (in the front-rear direction). Thus, even if the lens portion 3 tries to come off forward from the front frame 4, since the engaging portion 51 presses the lens portion 3 from the front, the lens portion 3 cannot move forward. Therefore, the engaging portion 51 can assist the connection state of the connecting portion 41 and the connected portion 33.

[0033] Further, the engaging portion 51 can press the connected portion 33 against the front frame 4 (connection portion 41) while being engaged with the lens portion 3. In the present embodiment, as described above, since at least a part of the connected portion 33 and the engaging portion 51 overlap in the front view with respect to the lens portion 3 (in the front-rear direction), it is easy to press the connected portion 33 by the engaging portion 51. Since the engaging portion 51 presses the connected portion 33 against the front frame 4 in addition to the engagement with the lens portion 3, the engagement state is strengthened, and the suppression of the dropout of the lens portion 3 can be made more reliable. Note that even if the connected portion 33 is pressed, the light-transmitting portion 31 may not be pressed. Rather, in order not to distort the light-transmitting portion 31, it is preferable that the light-transmitting portion 31 is not pressed by the engaging portion 51.

[0034] As described above, according to the present embodiment, in addition to the connection between the connection portion 41 of the front frame 4 and the connected portion 33 of the lens portion 3, the engaging portion 51 of the temple 5 engages with the lens portion 3. Therefore, since the lens portion 3 that is magnetically connected to the front frame 4 can be further engaged with the front frame 4 by the engaging portion 51, the advantage of making it difficult for the lens portion 3 to drop off from the front frame 4 can be exhibited.

[0035] As described above, one embodiment of the present invention has been described, but the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

[0036] For example, the connection portion 41 and the connected portion 33 are a combination of a magnet (permanent magnet) 331 and a magnetic body 411. However, the connection method is not limited to this. For example, a connection by fitting such as a combination of any one of a notch, a hole, a recess and a protrusion may be used, or a connection using a hook-and-loop fastener or a connection using an adhesive member may be used.

[0037] Further, in the above-described embodiment, the connected portion 33 of the lens portion 3 includes a magnet (permanent magnet) 331 and a frame-shaped magnet holding portion 332 in which the magnet 331 is embedded. However, for example, a configuration may be adopted in which the magnet holding portion 332 is not provided and the magnet 331 is directly fixed to the light-transmitting portion 31.

[0038] In the above embodiment, the engaging portion 51 is configured to engage with the lateral edge 3321 which is a part of the magnet holding portion 332 in the lens portion 3. However, the present invention is not limited to this, and it may be configured to engage with other portions (including the light transmitting portion 31) in the lens portion 3.

[0039] In the above embodiment, the connecting portions 41 (magnetic bodies 411) are provided on both the left and right sides of the front frame 4, and the engaging portions 51 are provided at the respective left and right ends of the pair of temples 5. However, the present invention is not limited to this, and different configurations may be provided for the left and right sides. Specifically, the connecting portion 41 (magnetic body 411) may be provided only on one side (left or right) of the front frame 4, and the engaging portion 51 may be provided only on the other side of the pair of temples 5. In this case, the other side of the front frame 4 may be configured to hold the lens portion 3 by engagement such as concavo-convex fitting instead of magnetic force. Further, even if the connecting portions 41 (magnetic bodies 411) are provided on both the left and right sides of the front frame 4 as in the above embodiment, the engaging portion 51 may be provided only on one side of the pair of temples 5.

[0040] Further, the engaging portion 51 may not be a part of the temple 5, but may be a separate member attached to the main body of the temple 5. Even in this case, the engaging portion 51 may be configured to approach and separate from the front frame 4 in conjunction with the opening and closing operation of the temple 5.

[0041] Further, the lens portion 3 may be in a form in which the light transmitting portion 31 is separated into a left eye portion 31L and a right eye portion 31R as shown in FIG. 7. In this case, for example, the functions of the connecting portions 41 and the engaging portions 51 on both the left and right sides of the front frame 4 and the pair of temples 5 are the same as those in the above embodiment, and the front frame 4 and the lens portion 3 may be configured to hold the lens portion 3 by engagement such as concavo-convex fitting in the vicinity of the nose pad 32. Conversely, connection may be made by magnetic force in the vicinity of the nose pad 32, and engagement may be performed by the engaging portion 51 on the side of the temple 5.
