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.

And a second locking portion extending toward the top, and at least one of the first locking portion and the second locking portion can be flexibly bent in the vertical direction. The first locking portion and the front In a state where the urging force is not acting on the second locking portion, the minimum vertical distance between the rear end portion of the first locking portion and the rear end portion of the second locking portion is The vertical distance between the front end portion of the first locking portion and the front end portion of the second locking portion is set smaller than the vertical thickness of the bridge portion of the spectacle frame. The thickness of the bridge portion of the spectacle frame is set substantially equal to the thickness in the vertical direction, and the length of the front end portion of the first locking portion or the front end portion of the second locking portion and the concave groove It is also provided as a front spectacle frame characterized in that the sum of the depth is set to be approximately equal to the thickness in the front-rear direction of the bridge portion of the spectacle frame.

  In the front spectacle frame according to the present invention, the bridge portion constituting the front spectacle frame includes a bridge portion main body in which a concave groove corresponding to the shape of the front surface of the bridge portion of the spectacle frame is formed, and a bridge portion main body. A first locking portion that extends rearward from the upper end of the groove, and has a length substantially equal to that of the first locking portion, from the lower end of the groove of the bridge portion body toward the rear. An extended second locking portion, and at least one of the first locking portion and the second locking portion is made of a flexible member that can be bent in the vertical direction. ing. 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 interval is set to be approximately 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 first locking portion or the second locking in which the vertical distance between the first locking portion and the second locking portion is set to be approximately equal to the vertical thickness of the bridge portion of the spectacle frame. The sum of the length of the front end portion) and the depth of the groove is set to be approximately equal to the thickness of the bridge portion of the spectacle frame 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.

  Further, in the state where the urging force is not acting on the first locking part and the second locking part, the upper and lower sides of the rear end part of the first locking part and the rear end part of the second locking part The minimum interval in the direction is set smaller than the thickness in the vertical direction of the bridge portion of the spectacle frame. Therefore, when the front spectacle frame is attached 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, If the hanging spectacle frame is moved rearward, the bridge portion of the spectacle frame abuts on the lower end of the rear end portion of the first locking portion and the upper end of the rear end portion of the second locking portion of the front spectacle frame. The rear end portion of the first locking portion is urged and bent upward, or the rear end portion of the second locking portion is urged and bent downward, or the first locking portion is bent. Since the rear end portions of both the locking portion and the second locking portion are bent, the vertical interval between the rear end portion of the first locking portion and the rear end portion of the second locking portion is increased. The bridge portion of the spectacle frame passes through the gap having the interval. 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 minimum vertical distance between the rear end portion of the first locking portion and the rear end portion of the second locking portion is smaller than the vertical thickness of the bridge portion of the spectacle frame, there is a gap having the interval. It becomes difficult for the bridge part of the eyeglass frame to come off. On the other hand, when removing the front spectacle frame from the spectacle frame, by moving the front spectacle frame forward, the front surface of the bridge portion of the spectacle frame comes out of the concave groove of the bridge portion main body of the front spectacle frame, and The bridge portion of the frame comes into contact with the rear end portion of the first locking portion and the second locking portion of the front spectacle frame, and the first locking portion is biased upward. The second locking portion is bent by being biased downward, or the rear end portions of both the first locking portion and the second locking portion are bent. The vertical interval between the rear end portion of the 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.

  As described above, the front spectacle frame according to the present invention can be easily and reliably attached to the spectacle frame without using magnetic force, and can be easily detached.

  Preferably, as described in claim 7 of the utility model registration claim, the eyeglass frame according to any one of claims 1 to 6, wherein the eyeglass frame is provided on the rear surface of both ends in the left-right direction of the front eyeglass frame. Concave grooves corresponding to the shape of the front surface of both ends in the left-right direction of the frame are provided.

  According to such a configuration, since the concave grooves corresponding to the shapes of the front surfaces of both ends in the left-right direction of the spectacle frame are provided on the rear surfaces of both ends in the left-right direction of the front spectacle frame, the front spectacle frame is used as the spectacle frame. When attached, the front surfaces of both ends in the left-right direction of the spectacle frame are engaged with the concave groove, so that the front spectacle frame can be more reliably attached to the spectacle frame.

  The present invention includes the front spectacle frame according to any one of claims 1 to 7 and the spectacle frame, as defined in claim 8 of the utility model registration claim. Also offered as a set.

  The front spectacle frame according to the present invention can be easily and reliably attached to the spectacle frame without using magnetic force, and can be easily detached. And since it is not necessary to use magnetic force, it has the outstanding advantage that it can attach or detach regardless of the kind of spectacles frame which the user is always using, and can also reduce manufacturing cost.

FIG. 2E is an enlarged sectional view showing the process, and FIG. 2E is an enlarged sectional view taken along the CC line in FIG.

  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 includes a bridge portion main body 111 in which a concave groove 111a corresponding to the shape of the front surface of the bridge portion 22 of the spectacle frame 2 is formed, and a concave groove 111a of the bridge portion main body 111. Extending downward from the rear end portion of the extending portion 112 so as to oppose the extending portion 112 extending rearward from the upper end and the concave groove 111a, and can be bent in the front-rear direction. And a locking portion 113 made of a flexible member (any material may be used as long as it has flexibility in addition to a flexible resin material or metal material). .

  And in the state (the state of Drawing 1 (b) and Drawing 2 (b)) where the energizing force does not act on locking part 113, the minimum of the direction part of bridge part main part 111 and the lower end part of locking part 113 is the minimum Is set smaller than the thickness T in the front-rear direction of the bridge portion 22 of the spectacle frame 2, while the front-rear direction interval T2 between the bottom of the concave groove 111 a and the locking portion 113 is equal to that of the spectacle frame 2. It is set substantially equal to the thickness T in the front-rear direction of the bridge portion 22.

  With the above configuration, in the state where the front spectacle frame 1 is attached to the spectacle frame 2 (the states of FIG. 1A and FIG. 2A), the bridge portion front surface 22a of the spectacle frame 2 is attached to the front spectacle frame 1. In the state where the bridge portion rear surface 22 b of the spectacle frame 2 is engaged with the concave groove 111 a of the bridge portion main body 111 and the front surface of the engagement portion 113 is engaged, the extending portion 112 is downwardly connected to the bridge portion 22 of the spectacle frame 2.

  The bridge portion 11C shown in FIG. 3C has a configuration in which the bridge portion 11B in FIG. More specifically, the bridge portion 11C is opposed to the bridge portion main body 111C, the extended portion 112C extending backward from the lower end portion of the bridge portion main body 111C, and the bridge portion main body 111C. The extending portion 112C extends upward from the rear end portion of the extending portion 112C, and includes a locking portion 113C made of a flexible member that can be bent in the front-rear direction. In the state in which the concave groove 113Ca corresponding to the shape of the rear surface of the bridge portion 22 of the frame 2 is formed and no urging force is applied to the locking portion 113C, the bridge portion main body 111C and the upper end portion of the locking portion 113C Is set smaller than the thickness T (see FIG. 2) of the bridge portion 22 of the spectacle frame 2 in the front-rear direction, while the bottom portion of the concave groove 113Ca and the bridge portion main body 111C. Interval T2 in the longitudinal direction of the is set substantially equal to the longitudinal direction thickness T of the bridge portion 22 of the eyeglass frame 2.

  As for the front spectacle frame including the bridge portion 11C according to the present embodiment, the direction of the attaching / detaching operation is the front spectacle frame 1 including the bridge portion 11 and the front spectacle frame including the bridge portion 11B. Except for the fact that it flips up and down, it has substantially the same operational effects, can be easily and reliably attached to the spectacle frame 2 without using magnetic force, and can be easily removed. However, since the bridge portion 11C according to the present embodiment is configured to open upward, the front spectacle frame moves downward due to its own weight as compared to the bridge portion 11 and the bridge portion 11B described above. The function to prevent is inferior. Therefore, it is preferable that the bridge portion 11C according to the present embodiment is also used in a relatively lightweight front spectacle frame, similarly to the bridge portion 11A described above.

  The bridge portion 11D shown in FIG. 3D includes a bridge portion main body 111D in which a concave groove 111Da corresponding to the shape of the front surface of the bridge portion 22 of the spectacle frame 2 is formed on the rear surface, and an upper end of the concave groove 111Da of the bridge portion main body 111D. The first locking portion 113Da extending from the rear to the rear has a length substantially equal to that of the first locking portion 113Da and is directed rearward from the lower end of the concave groove 111Da of the bridge portion main body 111D. And an extended second locking portion 113Db. And at least any one of 1st latching | locking part 113Da and 2nd latching | locking part 113Db consists of a flexible member which can bend in an up-down direction, 1st latching | locking part 113Da and 2nd In the state where the urging force is not acting on the locking portion 113Db, the minimum vertical distance H1 between the rear end portion of the first locking portion 113Da and the rear end portion of the second locking portion 113Db is While set to be smaller than the vertical thickness H (see FIG. 2) of the bridge portion 22 of the spectacle frame 2, the front end portion of the first locking portion 113Da and the front end portion of the second locking portion 113Db The vertical interval H2 is set to be approximately equal to the vertical thickness H of the bridge portion 22 of the spectacle frame 2, and the front end portion of the first locking portion 113Da or the second locking portion 113Db. And the depth of the groove 111Da Sum T3, are substantially equally set the front-rear direction of the thickness of the bridge portion 22 of the eyeglass frame 2 T (see FIG. 2).

  With the above configuration, when the front spectacle frame having the bridge portion 11D is attached to the spectacle frame 2, the front surface of the bridge portion 22 of the spectacle frame 2 is fitted into the concave groove 111Da of the bridge portion main body 111D of the front spectacle frame. Thus, the upper and lower surfaces of the bridge portion 22 of the spectacle frame 2 are sandwiched between the first locking portion 113Da and the second locking portion 113Db. Therefore, the movement of the bridge portion 11D of the front spectacle frame according to the present embodiment in the vertical direction and the rearward direction is restricted by the bridge portion 22 of the spectacle frame 2, and the front spectacle frame is reliably attached to the spectacle frame 2. It is possible to attach to.

  When the front spectacle frame according to this embodiment is attached to the spectacle frame 2, the gap between the first locking portion 113Da and the second locking portion 113Db of the front spectacle frame is set to the bridge portion 22 of the spectacle frame 2. If the front spectacle frame is moved rearward (rightward in the drawing of FIG. 2) after being disposed in the front, the bridge portion 22 of the spectacle frame 2 is moved to the rear end of the first locking portion 113Da of the front spectacle frame. The lower end of the first portion and the upper end of the rear end portion of the second locking portion 113Db, and the rear end portion of the first locking portion 113Da is urged upward to bend (first locking portion) 113Da is made of a flexible material) or the rear end portion of the second locking portion 113Db is biased downward to bend (the second locking portion 113Db is made of a flexible material). Case) or the first locking portion 113Da and the second locking portion 113. Since both rear end portions of b bend (when both the first locking portion 113Da and the second locking portion 113Db are made of a flexible material), the rear end portion of the first locking portion 113Da And the rear end portion of the second locking portion 113Db increase in the vertical direction, and the bridge portion 22 of the spectacle frame 2 passes through the gap having the interval. And after the bridge part 22 of the spectacles frame 2 passes the said clearance gap, 1st latching | locking part 113Da or 2nd latching | locking part 113Db, or both are the original states (state which biasing force does not act). The minimum vertical distance between the rear end portion of the first locking portion 113Da and the second locking portion 113Db is greater than the vertical thickness H of the bridge portion 22 of the spectacle frame 2. Therefore, the bridge portion 22 of the spectacle frame 2 is difficult to be removed from the gap having the interval.

  On the other hand, when removing the front spectacle frame from the spectacle frame 2, the front spectacle frame is moved forward so that the front surface of the bridge portion 22 of the spectacle frame 2 is recessed groove 111Da of the bridge portion main body 111D of the front spectacle frame. And the bridge portion 22 of the spectacle frame 2 contacts the rear end portion of the first locking portion 113Da and the rear end portion of the second locking portion 113Db of the front spectacle frame, and the first locking portion. 113Da is biased upward and bent, or the second locking portion 113Db is biased downward and bent, or the first locking portion 113Da and the second locking portion 113Db Since both rear end portions bend, the vertical distance between the rear end portion of the first locking portion 113Da and the rear end portion of the second locking portion 113Db is widened, and the spectacle frame extends from the gap having the interval. 2 Tsu will be shaped portion 22 comes out.

  Therefore, the front eyeglass frame including the bridge portion 11D according to the present embodiment can be easily and reliably attached to the eyeglass frame 2 without using magnetic force, and can be easily removed.

  The bridge portions 11, 11A, 11B, and 11C described with reference to FIGS. 2 and 3 have been described with respect to the configuration in which only the locking portion is made of a flexible member, but the present invention is not limited to this.
