Description

  The present invention relates to a front spectacle frame that does not have a temple that is detachably attached to the front surface of a spectacle frame having a temple, and a spectacle set using the same, and can be easily and surely attached without using magnetic force. Further, the present invention relates to a front spectacle frame that can be easily removed and a spectacle set using the same.

  Conventionally, for example, a configuration described in Patent Document 1 has been proposed as a spectacle set in which a front spectacle frame without a temple is detachably attached to the front surface of a spectacle frame having a temple. More specifically, the spectacles set described in Patent Document 1 (referred to as “glasses” in Patent Document 1) is a bridge portion of a spectacle frame (referred to as “main frame” in Patent Document 1). The upper surface of the spectacle frame (referred to as “bridge connector” in Patent Document 1) supports the bridge portion of the front spectacle frame (referred to as “attached frame” in Patent Document 1), The front spectacle frame is configured to be detachably attached to the spectacle frame by being magnetically attached to the bridge portion of the front spectacle frame.

  Among the spectacle sets of this type that have been proposed in the past, those that have been put into practical use can be mounted relatively firmly, so that the front spectacle frame is used as the spectacle frame as in the configuration described in Patent Document 1. In most cases, the front eyeglass frame is attached to the eyeglass frame using magnetic force.

  However, in order to generate the magnetic force, it is necessary to attach a magnet to the eyeglass frame and / or the front spectacle frame or to form a predetermined member (for example, a bridge portion) with the magnet. In addition, even when a magnet is attached to either one of the spectacle frame and the front spectacle frame, the part facing the other magnet of the spectacle frame or the front spectacle frame is also provided. It is necessary to attach a magnetic body (stainless steel or the like) to the body, or to form a member (for example, a bridge portion) provided at a portion facing the magnet with the magnetic body.

Therefore, in any case, since there is a restriction that a magnet or a magnetic body is attached to the spectacle frame (including a case where a predetermined member is formed of a magnet or a magnetic body), the type of the spectacle frame that is always used by the user. Depending on the model, it may not be possible to attach a front spectacle frame using this kind of magnetic force. As a result, the user purchases the entire spectacle set newly (that is, the spectacle frame and the front spectacle frame are purchased as a pair). ) There is a problem that must be done. Moreover, since it is necessary to attach a magnet to the eyeglass frame and / or the front eyeglass frame, there is a problem that the manufacturing cost increases.

The vertical distance between both ends in the left-right direction with the rear end of the two locking portions is set to be smaller than the vertical thickness of the bridge portion of the spectacle frame. The vertical distance between the front end portion and the front end portion of the second locking portion and the central portion in the left-right direction between the rear end portion of the first locking portion and the rear end portion of the second locking portion. The vertical interval is set to be approximately equal to the vertical thickness of the bridge portion of the spectacle frame, and the first locking portion The sum of the length of the front end portion of the end portion or the second locking portion and the depth of the concave groove is set to be approximately equal to the thickness in the front-rear direction of the bridge portion of the spectacle frame. A front spectacle frame is provided.

  In the front spectacle frame according to the present invention, the bridge portion constituting the front spectacle frame corresponds to the shape of the front surface of the bridge portion of the spectacle frame, and a bridge in which a concave groove into which the front surface of the bridge portion is fitted is formed on the rear surface A main body, a first locking portion extending rearward from the upper end of the concave groove of the bridge main body, and a length substantially the same as the first locking portion, the concave portion of the bridge main body A second locking portion extending rearward from the lower end of the groove, and at least one of the first locking portion and the second locking portion can be bent in the vertical direction. It consists of a flexible member. And in the state where biasing force is not acting on the 1st locking part and the 2nd locking part, the up-and-down direction of the front end part of the 1st locking part and the front end part of the 2nd locking part The vertical distance between the rear end portion of the first locking portion and the rear end portion of the second locking portion is substantially equal to the vertical thickness of the bridge portion of the spectacle frame. And the length of the front end portion of the first locking portion or the front end portion of the second locking portion (that is, the vertical direction between the first locking portion and the second locking portion). Is the sum of the length of the front end portion of the first locking portion or the second locking portion) and the depth of the concave groove. The thickness of the bridge portion of the spectacle frame is set substantially equal to the thickness in the front-rear direction. Therefore, when the front spectacle frame is attached to the spectacle frame, the front surface of the bridge portion of the spectacle frame is fitted into the concave groove of the bridge portion main body of the front spectacle frame, and the upper and lower surfaces of the bridge portion of the spectacle frame are the first engagement. It will be pinched between a stop part and a 2nd latching | locking part. Accordingly, the movement of the bridge portion of the front spectacle frame in the vertical direction and the rearward direction is restricted by the bridge portion of the spectacle frame, and the front spectacle frame can be securely attached to the spectacle frame.

  In addition, the first locking portion has convex portions protruding downward in the left and right end portions of the rear end portion, and / or the second locking portion is located on the left and right end portions of the rear end portion. Convex portions protruding in the direction are provided. And in the state where biasing force is not acting on the 1st locking part and the 2nd locking part, right and left of the rear end part of the 1st locking part and the rear end part of the 2nd locking part Vertical distance between both ends of the direction (that is, when a convex portion is provided only on the first locking portion, the vertical direction between the convex portion of the first locking portion and the second locking portion) When the convex portion is provided only on the second locking portion, the vertical spacing between the first locking portion and the convex portion of the second locking portion.

In a state where it does not act, the vertical distance between the rear end portion of the first locking portion and the rear end portion of the second locking portion in the left-right direction is determined by the bridge portion of the spectacle frame. While being set smaller than the thickness in the vertical direction, the distance between the front end of the first locking portion and the front end of the second locking portion in the vertical direction and after the first locking portion The vertical distance at the central portion in the left-right direction between the end portion and the rear end portion of the second locking portion is the thickness in the vertical direction of the bridge portion of the spectacle frame. The sum of the length of the front end portion of the first locking portion or the front end portion of the second locking portion and the depth of the concave groove is set to be substantially equal. It is also provided as a front spectacle frame characterized by being set substantially equal to the thickness in the front-rear direction of the portion.

  Also in the front spectacle frame according to the present invention, the bridge portion constituting the front spectacle frame corresponds to the shape of the front portion of the bridge portion of the spectacle frame, and a bridge in which a concave groove into which the front portion of the bridge portion is fitted is formed on the rear surface A main body, a first locking portion extending rearward from the upper end of the concave groove of the bridge main body, and a length substantially the same as the first locking portion, the concave portion of the bridge main body A second locking portion extending rearward from the lower end of the groove, and at least one of the first locking portion and the second locking portion can be bent in the vertical direction. It consists of a flexible member. And in the state where biasing force is not acting on the 1st locking part and the 2nd locking part, the up-and-down direction of the front end part of the 1st locking part and the front end part of the 2nd locking part The vertical distance between the rear end portion of the first locking portion and the rear end portion of the second locking portion is substantially equal to the vertical thickness of the bridge portion of the spectacle frame. And the length of the front end portion of the first locking portion or the front end portion of the second locking portion (that is, the vertical direction between the first locking portion and the second locking portion). Is the sum of the length of the front end portion of the first locking portion or the second locking portion) and the depth of the concave groove. The thickness of the bridge portion of the spectacle frame is set substantially equal to the thickness in the front-rear direction. Therefore, when the front spectacle frame is attached to the spectacle frame, the front surface of the bridge portion of the spectacle frame is fitted into the concave groove of the bridge portion main body of the front spectacle frame, and the upper and lower surfaces of the bridge portion of the spectacle frame are the first engagement. It will be pinched between a stop part and a 2nd latching | locking part. Accordingly, the movement of the bridge portion of the front spectacle frame in the vertical direction and the rearward direction is restricted by the bridge portion of the spectacle frame, and the front spectacle frame can be securely attached to the spectacle frame.

  The first locking portion includes a first protrusion protruding downward at either one of the left and right end portions of the rear end portion, and the second locking portion is a rear end. The second convex portion that protrudes upward to the other end portion (the end portion on the opposite side in the left-right direction from the end portion on which the first convex portion is provided) of either one of the left and right end portions of the portion It comprises. And in the state where biasing force is not acting on the 1st locking part and the 2nd locking part, right and left of the rear end part of the 1st locking part and the rear end part of the 2nd locking part The vertical interval at both ends in the direction is set smaller than the vertical thickness of the bridge portion of the spectacle frame. Accordingly, when attaching the front spectacle frame to the spectacle frame, after the gap between the first locking portion and the second locking portion of the front spectacle frame is disposed in front of the bridge portion of the spectacle frame, The front eyeglass frame may be moved rearward or the eyeglass frame may be moved forward. As a result, whether the bridge portion of the spectacle frame contacts the first convex portion and the second convex portion of the front spectacle frame, and the rear end portion of the first locking portion is biased upward and bends. Or the rear end portion of the second locking portion is biased downward and bent, or the rear end portions of both the first locking portion and the second locking portion are bent. The vertical gap between the rear end portion of the first locking portion and the rear end portion of the second locking portion is widened, and the bridge portion of the spectacle frame passes through the gap having the gap. Then, after the bridge portion of the spectacle frame passes through the gap, the first locking portion and / or the second locking portion returns to the original state (the state where the biasing force is not acting), Since the vertical distance between the rear end portion of the first locking portion and the rear end portion of the second locking portion in the left-right direction is smaller than the vertical thickness of the bridge portion of the spectacle frame, It is difficult for the bridge portion of the spectacle frame to come off from the gap having

  On the other hand, when removing the front spectacle frame from the spectacle frame, the front spectacle frame is moved forward, or the spectacle frame is moved rearward so that the front surface of the bridge portion of the spectacle frame is positioned on the front spectacle frame. The bridge portion of the spectacle frame comes into contact with the first convex portion and the second convex portion of the front spectacle frame, and the rear end portion of the first locking portion is directed upward. Urged and bent, or the rear end portion of the second locking portion is biased downward and bent, or the rear ends of both the first locking portion and the second locking portion Since the portion bends, the vertical interval between the rear end portion of the first locking portion and the rear end portion of the second locking portion is widened, and the bridge portion of the spectacle frame is removed from the gap having the interval. become.

  And in the front spectacles frame concerning the present invention, in the state where biasing force is not acting on the 1st locking part and the 2nd locking part, the rear end part of the 1st locking part and the 2nd The vertical spacing is not set to be smaller than the vertical thickness of the bridge portion of the spectacle frame over the entire length in the left-right direction with the rear end portion of the locking portion. Only the vertical distance between both ends is set smaller than the vertical thickness of the bridge part. That is, the first convex portion of the first locking portion is provided only at one end portion in the left-right direction, and the second convex portion of the second locking portion is provided only at the other end portion in the left-right direction. Therefore, the spectacles when attaching and detaching the front spectacle frame are compared with the case of adopting a configuration in which a convex portion is provided over the entire length in the left-right direction of the first locking portion and / or the second locking portion. As a result of the reduction in the contact area of the convex portion, the area of the convex portion with which the bridge portion of the frame abuts is reduced, and attachment / detachment is facilitated.

  As described above, the front spectacle frame according to the present invention also has an excellent advantage that it can be easily and reliably attached to the spectacle frame without using magnetic force, and can be easily detached.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram showing a schematic configuration of a front spectacle frame according to an embodiment of the present invention. FIG. 1 (a) is a plan view showing a state in which the front spectacle frame is attached to the spectacle frame. (B) is a plan view showing a state where the front spectacle frame is removed from the spectacle frame (part of the temple of the spectacle frame is not shown). 2 is an enlarged view of a part of the front spectacle frame according to the present embodiment. FIG. 2A is an enlarged cross-sectional view taken along the line AA in FIG. 1A, and FIG. Is an enlarged view of the BB cross section of FIG. 1 (a), FIG. 2 (c) is an enlarged view of the CC cross section of FIG. 1 (b), and FIG. 2 (d) is a view from the direction of the arrow D in FIG. 2 (e) is a cross-sectional enlarged view showing the transition process from the state shown in FIG. 2 (c) to the state shown in FIG. 2 (b) when the front spectacle frame is attached to the spectacle frame. FIG.2 (f) shows the EE cross-sectional enlarged view of Fig.1 (a).

  As shown in FIG. 1 or FIG. 2, the front spectacle frame 1 according to the present embodiment is configured not to have a temple but to be detachably attached to the front surface of the spectacle frame 2 having the temple 21. Has been.

  The bridge portion 11 constituting the front spectacle frame 1 corresponds to the shape of the front surface of the bridge portion 22 of the spectacle frame 2, and includes a bridge portion main body 111 in which a concave groove 111a into which the front surface of the bridge portion 11 is fitted is formed on the rear surface, A first locking portion 112 extending rearward from the upper end of the groove 111a of the main portion 111, and a length substantially equal to that of the first locking portion 112. And a second locking portion 113 extending rearward from the lower end of the groove 111a.

  At least one of the first locking portion 112 and the second locking portion 113 (both in the present embodiment) is a flexible member that can be bent in the vertical direction (a resin material having flexibility). In addition to metal materials, any material may be used as long as it has flexibility. And the 1st latching | locking part 112 comprises the convex part which protrudes below in the left-right direction both ends of a rear-end part, and / or the 2nd latching | locking part 113 is the left-right direction both ends of a rear end part And a convex portion protruding upward. In the present embodiment, the first locking portion 112 includes a convex portion 112a, and the second locking portion 113 includes a convex portion 113a.

  In a state where the urging force is not acting on the first locking portion 112 and the second locking portion 113, the rear end portion of the first locking portion 112 and the rear end portion of the second locking portion 113 The vertical interval H1 at both ends in the left-right direction is set smaller than the vertical thickness H of the bridge portion 22 of the spectacle frame 2. On the other hand, the vertical interval H2 (FIG. 2C) between the front end portion of the first locking portion 112 and the front end portion of the second locking portion 113, and the rear end portion of the first locking portion 112. The vertical distance H2 (FIG. 2 (d)) at the central portion in the left-right direction between the second locking portion 113 and the rear end portion of the second locking portion 113 is substantially equal to the vertical thickness H of the bridge portion 22 of the spectacle frame 2. Is set to be approximately equivalent. The sum T1 of the length of the front end portion of the first locking portion 112 or the front end portion of the second locking portion 113 and the depth of the concave groove 111a is the thickness T in the front-rear direction of the bridge portion 22 of the spectacle frame 2. Is set to be approximately equivalent.

  With the above configuration, when the front spectacle frame 1 having the bridge portion 11 is attached to the spectacle frame 2, the front surface 22a of the bridge portion 22 of the spectacle frame 2 is a concave groove of the bridge portion main body 111 of the front spectacle frame 1. The upper and lower surfaces of the bridge portion 22 of the spectacle frame 2 are sandwiched between the first locking portion 112 and the second locking portion 113. Accordingly, the vertical movement and the backward movement of the bridge portion 11 of the front spectacle frame 1 are restricted by the bridge portion 22 of the spectacle frame 2, and the front spectacle frame 1 is securely attached to the spectacle frame 2. Is possible.

  When the front spectacle frame 1 according to this embodiment is attached to the spectacle frame 2, the gap between the first locking portion 112 and the second locking portion 113 of the front spectacle frame 1 is used as a bridge of the spectacle frame 2. After being arranged in front of the portion 22, the front spectacle frame 1 may be moved backward (in the direction of the arrow in FIG. 2E), or the spectacle frame 2 may be moved forward. As a result, the bridge portion 22 of the spectacle frame 2 contacts the convex portion 112a of the first locking portion 112 and the convex portion 113a of the second locking portion 113 of the front spectacle frame 1, and the first locking portion. The rear end portions of both 112 and the second locking portion 113 bend in a direction away from each other (in the direction of the white arrow in FIG. 2 (e)) (from the state indicated by the broken line in FIG. 2 (e)). Therefore, the vertical interval between the rear end portion of the first locking portion 112 and the rear end portion of the second locking portion 113 is widened, and the gap having the interval is set to the spectacle frame. The two bridge portions 22 pass through. And after the bridge part 22 of the spectacles frame 2 passes the said clearance gap, both the 1st latching | locking part 112 and the 2nd latching | locking part 113 will be in the original state (state which the urging | biasing force does not act). Returning, the vertical distance H1 between the rear end portion of the first locking portion 112 and the rear end portion of the second locking portion 113 in the left-right direction is the thickness of the bridge portion 22 of the spectacle frame 2 in the vertical direction. Since it becomes smaller than H, it becomes difficult for the bridge portion 22 of the spectacle frame 2 to come off from the gap having the interval.

  On the other hand, when the front spectacle frame 1 is removed from the spectacle frame 2, the front spectacle frame 1 is moved forward or the spectacle frame 2 is moved rearward so that the front surface of the bridge portion 22 of the spectacle frame 2 is removed. Comes out of the concave groove 111a of the bridge portion main body 111 of the front spectacle frame 1, and the bridge portion 22 of the spectacle frame 2 is connected to the convex portion 112a and the second engagement of the first locking portion 112 of the front spectacle frame 1. Since the rear end portions of both the first locking portion 112 and the second locking portion 113 are bent in contact with the convex portion 113a of the portion 113, the rear end portion of the first locking portion 112 and the second locking portion 112 are The vertical interval with the rear end portion of the locking portion 113 increases, and the bridge portion 22 of the spectacle frame 2 comes out from the gap having the interval.

  In the front spectacle frame 1 according to the present embodiment, the rear of the first locking portion 112 in a state where the urging force is not acting on the first locking portion 112 and the second locking portion 113. The vertical distance between the end portion and the rear end portion of the second locking portion 113 is set to be smaller than the vertical thickness of the bridge portion 22 of the spectacle frame 2. Rather, only the vertical interval H1 of a part (both ends in the left-right direction) is set to be smaller than the vertical thickness H of the bridge portion 22. That is, since the convex portion 112a of the first locking portion 112 and the convex portion 113a of the second locking portion 113 are provided only at both end portions in the left-right direction, the first locking portion 112 and / or the first locking portion 112a. Compared to the case where a configuration in which a convex portion is provided over the entire length of the two locking portions 113 in the left-right direction is adopted, the convex region where the bridge portion 22 of the spectacle frame 2 abuts when the front spectacle frame 1 is attached and detached. As a result, the contact resistance of the convex portion is reduced, and attachment / detachment is facilitated.

  Therefore, the front spectacle frame 1 according to the present embodiment has an excellent advantage that it can be easily and reliably attached to the spectacle frame 2 without using magnetic force, and can be easily detached.

  In addition, the front spectacle frame 1 according to the present embodiment preferably has a concave groove 12 corresponding to the shape of the front surface of both ends of the spectacle frame 2 on the rear surface of both ends of the spectacle frame 2 as a preferable configuration. Is provided.

  With such a preferable configuration, when the front spectacle frame 1 is attached to the spectacle frame 2, the front surfaces of both ends in the left and right direction of the spectacle frame 2 are engaged with the concave groove 12 (see FIG. 2 (f)). It is possible to attach the front spectacle frame 1 to the spectacle frame 2 more reliably.

  In addition, in this embodiment, although the structure which only the 1st latching | locking part 112 with which the bridge | bridging part 11 is equipped and the 2nd latching | locking part 113 consists of a flexible member was demonstrated, this invention is not restricted to this. The bridge portion main body 111 can also be formed of a flexible member, and the bridge portion main body 111 and the first locking portion 112 and / or the second locking portion 113 can be integrally formed. .

  Moreover, in this embodiment, the 1st latching | locking part 112 of the bridge | bridging part 11 comprises the convex part 112a which protrudes below in the left-right direction both ends of a rear-end part, and the 2nd latching | locking part 113 is a rear end. Although the configuration in which the convex portions 113a projecting upward at both ends in the left and right direction of the portion has been described, the present invention is not limited to this, and as shown in FIG. The first protrusion 112a ′ projecting downward is provided at one of the left and right ends of the end, and the second locking portion 113 is provided at both ends of the left and right of the rear end.
