Description

  The present invention relates to a replaceable temple frame for a temple.

  In recent years, emphasis has been placed on decorative functionality such as fashionability and design for spectacle frames, and various spectacle frames whose appearance can be changed according to TPO (Time, Place, Occasion) have been proposed. Has been. One of the spectacle frames whose appearance can be changed is a spectacle frame whose temples can be replaced.

As a spectacle frame in which the temple can be replaced, for example, a spectacle frame employing a coupling mechanism disclosed in Patent Document 1 can be cited. This connection mechanism is composed of a temple having an insertion plug formed at the front end portion and a hinge having a socket into which a temple insertion plug is inserted formed at the rear end portion. In such a connection mechanism, when a temple plug is inserted into a hinge socket, the temple and the hinge are connected. On the other hand, when the temple inserted into the hinge socket is pulled out behind the hinge, the connection between the temple and the hinge can be released. As described above, the spectacle frame employing the connection mechanism disclosed in Patent Document 1 can freely connect the temple and the hinge and release the connection. By selecting a temple, the appearance can be made according to TPO.
JP 2001-117052 A

  However, since the connection mechanism is configured to release the connection between the temple and the hinge by pulling the temple rearward, if a backward force is applied to the temple due to an impact or a temple opening / closing operation, the difference between the temples is determined. There is a risk that the plug will come out of the hinge socket and the temple will be easily removed from the hinge. That is, there is a possibility that the temple may come off against the intention of the wearer of the spectacle frame, even when the temple is not replaced.

  It is an object of the present invention to provide a spectacle frame in which a temple can be replaced in which the temple is prevented from easily coming off.

  According to a first aspect of the present invention, a front frame, a locking member that is rotatably connected to the front frame, and a temple that is removably engaged with the locking member, The locking member includes an open position where the front frame is present forward, and a closed position where the front frame is rotated forward with respect to the front frame from the state of the open position. The temple is engaged with the locking member so as to be freely disengageable from the front of the locking member in the closed position, and the engagement portion engages with the locking member. The eyeglass frame is provided with a retaining portion that is positioned in front of the locking member and prevents the engaging portion from being pulled out rearward of the locking member.

  The eyeglass frame according to the present invention includes a locking member that is rotatably connected to the front frame, and a temple that is removably engaged with the locking member. The temple is replaced with the locking member. Possible configuration. Such a temple has an engaging portion that is detachably engaged with the locking member from the front of the locking member. On the other hand, the locking member is configured to be able to take an open position where the front frame is present forward and a closed position which is rotated from the open position and does not have the front frame forward. When the locking member is in the closed position where the front frame does not exist in front, the temple is engaged with the locking member from the front of the locking member. Can be done. Further, the engagement between the temple and the locking member can be released by moving the engaging portion of the temple forward of the locking member when the locking member is in the closed position.

  The eyeglass frame according to the present invention can be mounted with the temple hooked on the ear by rotating the locking member to the open position after engaging the temple with the locking member as described above. When the locking member is in the open position, there is a front frame in front of the locking member. Therefore, when the locking member is in the open position, the front frame engages the engaging portion of the temple. It is prevented from slipping forward of the stop member. Therefore, in the spectacle frame according to the present invention, it is possible to prevent the temple engaging part from coming out of the locking member and detaching the temple from the locking member during mounting. In addition to the engaging portion, the temple is positioned in front of the locking member when the engaging portion is engaged with the locking member, and prevents the engaging portion from coming out behind the locking member. It has a retaining part. Therefore, even if the temple is about to move rearward of the locking member when the engaging portion is engaged with the locking member, the retaining portion prevents the engaging portion from coming out rearward of the locking member. The Therefore, in the spectacle frame according to the present invention, it is also possible to prevent the engaging portion from coming out behind the locking member and the temple from being detached from the locking member.

  As a preferred configuration of the present invention, as described in claim 2 of the claims, the engaging portion has an insertion portion into which the locking member is inserted, and the front end portion of the locking member The engaging member is engaged with the engaging member by inserting the engaging member into the insertion portion. When the engaging member is inserted into the inserting portion, the engaging member is elastically contracted in a direction perpendicular to the front-rear direction. The structure which is a state can be mentioned.

  In such a preferable configuration, the engaging portion has an insertion portion into which the locking member is inserted, and is configured to engage with the locking member by inserting the locking member into the insertion portion. On the other hand, when the locking member is inserted into the insertion portion, the locking member is elastically contracted in a direction perpendicular to the front-rear direction. In other words, in a state where the engaging portion is engaged with the locking member, the locking member presses the insertion portion from the inside by the elastic force, so that the temple is prevented from moving in the front-rear direction with respect to the locking member. It becomes easy to be done. Therefore, in this preferable structure, it can prevent more reliably that a temple remove | deviates from a latching member in the state engaged with the latching member.

  As a specific configuration of the locking member, as described in claim 3 of the claims, the locking member may include a configuration in which a cutout portion extending in the front-rear direction is formed on the inner side from the side surface portion.

  As a preferred configuration of the present invention, as described in claim 4 of the claims, the locking member has a convex portion or a concave portion on a side surface portion, and the insertion portion is the convex portion or the concave portion. The structure which has the recessed part or convex part which fits can be mentioned.

  According to such a preferable configuration, the convex portion or the concave portion is provided on the side surface portion of the locking member that presses the insertion portion from the inside by the elastic force when inserted into the insertion portion, and the convex portion or the concave portion provided on the locking member. A recess or projection that fits into the recess is provided in the insertion portion. As described above, when the locking member is inserted into the insertion portion, it presses the insertion portion from the inside by elastic force. Therefore, when the locking member is inserted into the insertion portion, the convex portion or the concave portion provided in the locking member is pressed and fitted into the concave portion or the convex portion provided in the insertion portion by the elastic force that presses the insertion portion from the inside. Include. Thus, since the convex part or recessed part provided in the latching member fits into the concave part or convex part of an insertion part with an elastic force, the latching member and insertion part are firmly unevenly fitted. Therefore, in a state where the engaging portion is engaged with the locking member (a state where the locking member is inserted into the insertion portion), the movement of the temple in the front-rear direction with respect to the locking member is further easily prevented. Therefore, according to such a preferable configuration, the locking member further presses the insertion portion with the elastic force from the inside, and the temple is further removed from the locking member due to the concave-convex fitting between the locking member and the insertion portion. This can be prevented more reliably. When the temple is removed from the locking member when the temple is replaced, the locking portion is turned to the closed position, and the temple engaging portion is moved forward of the locking member. When the temple is moved forward, the concave / convex fitting between the convex portion or concave portion provided in the locking member and the concave portion or convex portion provided in the insertion portion of the temple is released. When the temple is further moved forward, the temple is extracted forward by the locking member. Thereby, engagement with an engaging part and a locking member is cancelled | released, and a temple can be removed from a locking member.

The top view seen from the Z direction is shown. As shown in FIG. 6, the temple 4 includes an engaging portion 41 that is detachably engaged with the locking member 3 from the front of the locking member 3 in the open position, and the engaging portion 41 is connected to the locking member 3. It has a retaining portion 42 that is positioned in front of the locking member 3 and prevents the engaging portion 41 from coming out rearward of the locking member 3 when engaged.

  The temple 4 is formed of an elongated member 40 as shown in FIG. An engagement portion 41 and a retaining portion 42 are formed at one end portion of the elongated member 40, and a tip cell portion 43 that is curved downward is formed at the other end portion. As shown in FIGS. 6B and 6C, the engagement portion 41 has an insertion portion 44 having a space 45 in which the other side portion 32 of the locking member 3 is inserted inside. The engaging part 41 is engaged with the locking member 3 by inserting the other side part 32 into the space 45 from the front end part (part on the arrow T1 direction side in FIG. 4).

  As shown in FIG. 6B, the space 45 is formed in a shape that is long in the direction of one end and the other end of the elongated member 40. As shown in FIG. 6 (d), in this space 45, a portion on the other end side of the elongated member 40 (hereinafter referred to as the other end portion 45a) is opened, and the locking member 3 is inserted from the other end portion 45a. It is possible to do. The space 45 has a rectangular cross section as shown in FIG. This cross section is formed such that the vertical length H3 is smaller than the vertical length H2 of the other side portion 32 (see FIG. 5), and the width direction length W3 is the width direction length W2 of the other side portion 32 (see FIG. 5). It is formed substantially the same as (see FIG. 5).

  The retaining portion 42 is located at a portion of the space 45 opposite to the other end portion 45a (hereinafter referred to as one end portion 45b). In the present embodiment, the end portion 45 b of the space 45 is completely closed by the retaining portion 42. Since the retaining portion 42 is located at the one end portion 45b of the space 45, the other side portion 32 inserted into the space 45 is prevented from coming off from the one end portion 45b of the space.

  Further, as shown in FIG. 6B, a convex portion 47 fitted to the concave portion 34 formed on the other side portion 32 of the locking member 3 is formed on the inner peripheral surface portion of the insertion portion 44 that forms the space 45. Is provided. In this embodiment, the convex part 47 is provided above and below the inner peripheral surface part.

  Furthermore, as shown in FIGS. 6A to 6D, the insertion portion 44 is formed with a slit 46 that penetrates the outer peripheral surface portion and the inner peripheral surface portion of the insertion portion 44. The slit 46 is formed so as to extend from the end on the other end side (the front cell portion 43 side) of the elongated member 40 forming the temple 4 to the one end side of the elongated member 40. The width U of the slit 46 is formed to be the same as or slightly larger than the vertical length H1 of the one side 31 of the locking member 3.

  With regard to the spectacle frame 1 having the above configuration, the engagement / disengagement of the temple 4 and the mounting of the spectacle frame 1 will be described. FIG. 7 is an explanatory view showing a procedure for engaging / disengaging the temple 4 and mounting the spectacle frame 1. FIG. 7 (a) shows a state before the temple 4 is engaged with the locking member 3, and FIG. ) Shows a state after the temple 4 is engaged with the locking member 3, and FIG. 7C shows a state of the spectacle frame 1 when the spectacle frame 1 is mounted. As shown in FIG. 7A, when the temple 4 is engaged with the locking member 3, the locking member 3 is rotated to the closed position. Then, the temple 4 is moved so that the other end portion 45 a of the space 45 of the temple 4 is positioned in front of the other side portion 32 and the slit 46 is positioned in front of one side portion 31 of the temple 4. Next, the temple 4 is moved behind the other side 3 (in the direction of arrow E in FIG. 7A). As a result, as shown in FIG. 7B, the other side portion 32 is inserted into the space 45 from the front end portion through the opening of the space 45, and the one side portion 31 of the locking member 3 is inserted into the slit 46. .

  In the present embodiment, the vertical length H3 of the space 45 is smaller than the vertical length H2 of the other side portion 32. However, as shown in FIG. 4, since the front surface portion 35 of the other side portion 32 is formed in a substantially arc shape when viewed from the side, the other side portion 32 pushes the opening side of the insertion portion 44 with this front surface portion 35. You can enter the space 45 while spreading. Therefore, even if the vertical length H3 of the space 45 is smaller than the vertical length H2 of the other side portion 32, the other side portion 32 can be smoothly inserted into the space 45.

  Further, since the vertical length H3 of the space 45 is formed to be smaller than the vertical length H2 of the other side portion 32, when the other side portion 32 is inserted into the space 45, the other side portion 32 is The inner peripheral surface portion of the insertion portion 44 is pressed so as to contract in the vertical direction. By this pressing, the other side portion 32 is elastically contracted in the vertical direction. As described above, the other side portion 32 is elastically contracted in the vertical direction by the pressing of the inner peripheral surface portion, so that the upper surface portion and the lower surface portion of the side surface portion of the other side portion 32 resist the pressing force of the inner peripheral surface portion. The inner peripheral surface portion is pressed in the vertical direction by an elastic force from the inside. In this manner, the other side portion 32 presses the insertion portion 44 from the inside, whereby the movement of the temple 4 in the front-rear direction with respect to the locking member 3 is easily prevented.

  Moreover, the recessed part 34 is provided in the upper surface part and lower surface part of the other side part 32 which presses the internal peripheral surface part of the insertion part 44 to an up-down direction from an inner side. Therefore, when the other side portion 32 is inserted into the space 45 to a position where the convex portion 47 provided on the inner peripheral surface portion of the insertion portion 44 of the temple 4 and the concave portion 34 provided on the other side portion 32 can be fitted, The concave portion 34 is pressed against the convex portion 47 by an elastic force that presses the inner peripheral surface portion of the insertion portion 44 in the vertical direction from the inside, and is fitted to the convex portion 47. By this uneven fitting, movement of the temple 4 in the front-rear direction with respect to the locking member 3 is easily prevented. Further, since the concave portion 34 is pressed against the convex portion 47 by the elastic force and is fitted to the convex portion 47, the concave and convex fitting between the concave portion 34 and the convex portion 47 is performed firmly, and the temple 4 is fixed to the locking member 3. The movement in the front-rear direction is surely easily prevented.

  In this way, the other side portion 32 is inserted into the space 45, whereby the engaging portion 41 engages with the locking member 3. When the engaging portion 41 engages with the locking member 3, as shown in FIG. 7C, the locking member 3 is rotated to the open position, the tip cell portion 43 of the temple 4 is hooked on the ear, and the nose The spectacle frame 1 can be worn with the pad 25 on the nose.

  Further, to release the engagement between the temple 4 and the locking member 3, first, the locking member 3 is rotated to the closed position. Next, the temple 4 is moved to the front of the locking member 3, and the convex portion 47 formed on the inner peripheral surface portion of the insertion portion 44 is moved to the front to form the convex portion 47 and the locking member 3. The fitting with the recessed portion 34 is released. Thereafter, the temple 4 is further moved to the front of the locking member 3, the other side portion 32 of the locking member 3 is extracted backward from the space 45, and the one side portion 31 of the locking member 3 is moved from the rear of the slit 46. Let it be extracted. Thereby, the engagement between the temple 4 and the locking member 3 is released. Thus, since the spectacle frame 1 of this embodiment can engage the temple 4 and the locking member 3 and release the engagement, the temple 4 can be replaced.

  As shown in FIG. 7C, when the locking member 3 takes the open position, the outer portion 23 of the rim portion 22 of the front frame 2 exists in front of the locking member 3. For this reason, in the spectacle frame 1, the engaging portion 41 of the temple 4 is prevented from coming out of the front of the locking member 3 at the time of wearing, and the temple 4 is prevented from being detached from the front of the locking member 3. Further, the retaining portion 42 is located at one end 45 b of the space 45. Therefore, even when the engaging portion 41 is engaged with the other side portion 32, even if the temple 4 tries to move rearward with respect to the other side portion 32 of the locking member 3, the retaining portion 42 causes the temple 4 to move. The rearward movement is prevented and the temple 4 is also prevented from coming off the rear of the locking member 3.

  Furthermore, as described above, in the spectacle frame 1 of the present embodiment, the other side portion 32 presses the insertion portion 44 from the inside, and the concave portion 34 formed in the locking member 3 and the inner periphery of the insertion portion 4. Also by the convex and concave portions 47 formed on the surface portion being concavo-convexly fitted, the movement of the temple 4 in the front-rear direction with respect to the locking member 3 is easily prevented. Therefore, in the eyeglass frame 1 of the present embodiment, the movement of the temple 4 with respect to the locking member 3 is more reliably prevented, and the temple 4 is further reliably prevented from being detached from the locking member 3.

  Hereinafter, modified examples of the spectacle frame 1 will be described. In the present embodiment, the other side 32 of the locking member 3 has a notch 33 formed at one place in the center in the vertical direction, but the notches 33 are formed at two or more different positions in the vertical direction. May be. For example, as shown to Fig.8 (a), the other side part 32 may be the shape where the notch part 33 was formed in two places which are different in an up-down direction, and the rear-end part was divided into three forks. Further, the notch 33 is not formed up to the rear end of the other side, and the other side 32 may be formed in an annular shape as viewed from the side as shown in FIG. Further, as shown in FIG. 8C, the notch 33 is formed so as to extend rearward from the front end, and the other side 32 has a shape in which the front end is divided into two or more. Also good.

  In the present embodiment, in order to easily prevent the temple 4 from moving in the front-rear direction with respect to the locking member 3, the other side portion 32 is elastically contracted in the up-down direction when inserted into the space 45. The inner peripheral surface portion of the insertion portion 44 is configured to be pressed in the vertical direction from the inside. However, the direction in which the other side portion 32 presses the inner peripheral surface portion of the insertion portion 44 is not limited to the vertical direction, and may be a direction perpendicular to the front-rear direction of the other side portion 32. As an example of the pressing direction, the width direction (In the direction of arrow W in FIG. 6C). As the configuration in which the other side portion 32 elastically presses the inner peripheral surface portion of the insertion portion 44 in the width direction from the inside, for example, the other side portion 32 can be elastically deformed in the width direction, and the other side portion 32 A configuration in which the width direction length W2 is formed larger than the width direction length W3 of the space 45 can be given. As a configuration in which the other side portion 32 can be elastically deformed in the width direction, a configuration in which the notch portion 33 is formed in the center portion in the width direction of the other side portion 32 can be exemplified. FIG. 9 is a plan view of the vicinity of the left locking portion 3 of the spectacle frame 1 in which a notch 33 is formed at the center in the width direction of the other side portion 32. As shown in FIG. 9, the notch 33 is formed so as to extend forward from the rear end of the other side 32, and the other side 32 has a substantially U shape in plan view with the rear end divided into two. Is formed. The configuration in which the other side portion 32 is easily elastically deformed in the width direction is not limited to the configuration shown in FIG. 9 .For example, in plan view, the rear end portion of the other side portion 32 is trifurcated, or more, or The structure which formed the notch part 33 so that the front-end part of the other side part 32 may be divided into two forks, three forks, or more can be mentioned.

  In the present embodiment, the notch 33 is formed in the other side 32 so that the other side 32 can be elastically contracted. However, instead of the notch 33, a material having elasticity is used for the other side 32. Thus, the other side portion 32 may be elastically contractible.

  Further, in this embodiment, the recess 34 is formed on the other side 32 of the locking member 3 and the convex 47 is formed on the inner peripheral surface of the insertion portion 44, but the other side 32 of the locking member 3. A convex portion may be formed on the inner peripheral surface of the insertion portion 44, and a concave portion 47 may be formed on the inner peripheral surface portion of the insertion portion 44.

  Further, the eyeglass frame 1 of the present invention is replaced with the temple 4 (see FIG. 6) of the present embodiment in order to prevent the eyeglass frame 1 from slipping off when performing intense exercise such as sports. The temple 4 having the tip cell portion 43 shown in FIG. The temple 4 having the tip cell portion 43 shown in FIG. 10 includes an elongated member 40, an ear pad member 71 and an entanglement preventing member 75 which will be described later. The elongate member 40 has the same configuration as the elongate member 40 of the temple 4 of the present embodiment, and an engaging portion and a retaining portion are formed at one end, and the other end is shown in FIG. A tip cell portion 43 is formed. As shown in FIG. 10, the ear contact member 71 includes an ear contact portion 72 capable of contacting the ear and a pin or a screw for swingably attaching the tip cell portion 43 of the temple 4 and the ear contact portion 72. It has a swinging portion 73 to which a shaft member 7 such as a shaft is attached. The entanglement preventing member 75 connects the predetermined portion 4c on the proximal end side 4b with respect to the portion 4a to which the ear contact member 71 of the elongated member 40 is attached and the proximal end side 4b end region 72a of the ear contact portion 72. It is a member to do.

  The eyeglass frame using the temple 4 is worn by hooking the ear contact portion 72 of the curved ear pad 71 on the ear and the nose pad 25 (see FIG. 1) attached to the front frame 2 on the nose. can do.

  In this spectacle frame, if the front frame is about to fall off while the spectacle frame is being put on, the tip cell portion 43 and the ear contact portion 72 of the ear pad member 71 tend to slip up. Then, when the ear contact part 72 of the ear pad member 71 tries to move upward, the swinging part 73 (the ear pad member 71 is attached) which is a part attached to the tip cell part 43 of the temple 4 of the ear pad member 71. The ear contact portion 71 tends to rotate clockwise in FIG. 10 around the shaft member 7 inserted through the portion 4a). At this time, the force with which the proximal end side 4b end region 72a of the ear contact portion 72 presses the ear increases, and as a result, the relative movement between the ear contact portion 72 and the ear is prevented, and the front cell The shift of the portion 43 is prevented. In this way, it is possible to prevent the glasses frame from falling off.

  Further, as shown in FIG. 10, the flexible entanglement preventing member 75 has a predetermined portion 4 c on the base end side 4 b from the portion 4 a to which the ear contact member 71 of the elongated member 40 is attached and the ear of the ear contact member 71. The base end side 4b end region 72a of the contact portion 72 is attached so as to be connected. By doing so, even when the temple 4 is lifted upward when removing the spectacle frame, the slender member 40 and the proximal end side 4b end region 72a of the ear contact portion 72 are prevented from being entangled. Since it is blocked by the member 75, it is difficult for the hair to enter the attachment portion (the swinging portion 73) between the tip cell portion 43 and the ear contact portion 72 from the Q direction, and the entanglement is suppressed. Further, since the entanglement preventing member 75 has flexibility, it does not hinder the function of suppressing the omission of the spectacle frame. In this way, the predetermined portion 4c on the proximal end side 4b and the proximal end side 4b of the ear contact portion 72 from the portion 4a where the ear contact member 71 of the elongated member 40 is attached by the flexible entanglement preventing member 75. By connecting the end region 72a, it is possible to prevent the glasses from slipping off without increasing the load on the nose, and to prevent the hair from getting entangled with the glasses when the spectacle frame is removed.
