Front glasses frame and glasses set

Technical field

[0001] The present invention relates to a front spectacle frame that does not include a temple that is detachably attached to the front surface of a spectacle frame that includes a temple. The present invention relates to a front spectacle frame that can be easily and reliably attached without being easily removed, and a spectacle set using the same.

Background art

Conventionally, for example, a configuration described in Patent Document 1 has been proposed as a spectacle set in which a front spectacle frame is detachably attached to a front surface of a spectacle frame including a temple without the temple. More specifically, the eyeglass set described in Japanese Patent No. 3355120 (referred to as “glasses” in the above publication) is referred to as an eyeglass frame (referred to as “main frame” in the above publication), The upper surface of the bridge portion (referred to as “bridge connector” in the above publication) supports the bridge portion of the front spectacle frame (referred to as “attached frame” in the above publication) and The upper surface of the bridge portion and the bridge portion of the front spectacle frame are magnetically attached, so that the front spectacle frame can be detachably attached to the spectacle frame.

[0003] Of these types of spectacle sets that have been proposed in the past, those that have been put to practical use can be attached relatively firmly, and therefore, as in the configuration described in the above publication, the front spectacle frame is used. In most cases, the frame is magnetically attached to the eyeglass frame, that is, the front eyeglass frame is attached to the eyeglass frame using magnetic force.

[0004] In order to generate a magnetic force while applying a force, a magnet is attached to or either one of the spectacle frame and the front spectacle frame, or a predetermined member (for example, a bridge portion or the like) is formed of a magnet. There is a need. In addition, even if a magnet is attached to either the spectacle frame or the front spectacle frame, either the spectacle frame or the front spectacle frame may be attached to a portion facing the other magnet. A force for attaching a magnetic body (stainless steel, etc.), or a member (on a part facing the magnet) For example, it is necessary to form a bridge portion or the like with a magnetic material.

Accordingly, in any case, 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). Depending on the type of frame, it may not be possible to attach a front spectacle frame that uses this type of magnetic force, and as a result, the user purchases a new spectacle set (i.e., spectacle frame and front spectacle frame). There is a problem that they must be purchased as a pair. In addition, 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.

Disclosure of the invention

[0006] The present invention has been made to solve such problems of the prior art, and can be easily and reliably attached without using magnetic force, and the front spectacle frame that can be easily detached. It is an object of the present invention to provide a spectacle set using the above.

[0007] The present invention that solves the above-described problems includes a temple that is detachably attached to the front surface of the eyeglass frame that includes the temple according to claim 1 of the claims. Incidentally, the front spectacle frame, 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 concave groove into which the front surface of the bridge portion is fitted is formed on the rear surface. The bridge portion main body, the upper end force of the concave groove of the bridge portion main body, the extended portion extending rearward, and the rear end force of the extended portion so as to face the concave groove in the front-rear direction In the state where the urging force is not acting on the locking portion and the bridge portion main body in a state in which a urging force is not applied to the locking portion. Minimum in the front-rear direction with the lower end of the locking part Spacing force is set to be smaller than the thickness in the front-rear direction of the bridge portion of the spectacle frame, while the front-rear direction interval between the bottom of the concave groove and the locking portion is that of the pledge portion of the spectacle frame. The present invention provides a front spectacle frame that is set to be approximately equal to the thickness in the front-rear direction and is attached to and detached from the spectacle frame by an attaching and detaching operation in the vertical direction.

[0008] In the front spectacle frame according to the present invention, a bridge constituting the front spectacle frame. Corresponding to the shape of the front surface of the bridge portion of the spectacle frame, the bridge portion main body in which a concave groove into which the front surface of the bridge portion is fitted is formed on the rear surface, and the upper end of the concave groove of the bridge portion main body toward the rear An extended portion that is extended, and a locking portion that is extended downward from the rear end of the extended portion so as to face the concave groove in the front-rear direction and can be held in the front-rear direction. It is set as the structure provided with. In the state where the urging force is not applied to the locking portion, the spacing force between the bottom portion of the concave groove and the locking portion is set to be approximately equal to the thickness in the front-rear direction of the bridge portion of the spectacle frame. 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 rear surface of the bridge portion of the spectacle frame is the locking portion. The extended portion is supported by the bridge portion of the spectacle frame in a downward force state while being engaged with the front surface of the eyeglass frame. Therefore, the movement of the bridge portion of the front spectacle frame in the front-rear direction and the downward direction is regulated by the bridge portion of the spectacle frame, and the front spectacle frame can be securely attached to the spectacle frame. .

In addition, when the urging force is not applied to the locking part, the minimum distance in the front-rear direction between the bridge part body and the lower end of the locking part is set smaller than the thickness in the front-rear direction of the bridge part of the spectacle frame. Has been. Therefore, when the front spectacle frame is attached to the spectacle frame, the extending portion of the front spectacle frame is disposed above the bridge portion of the spectacle frame and then the front spectacle frame is moved downward, Since the bridge part of the frame abuts the lower end part of the locking part of the front-hanging ophthalmoscope frame and the locking part is biased toward the rear, the bridge part body and the lower end part of the locking part are The interval in the front-rear direction is increased, and the bridge portion of the spectacle frame easily passes through the gap having the interval. Then, after the bridge portion of the spectacle frame passes through the gap, the locking portion returns to the original state (the state where the urging force is not acting), and the bridge portion main body and the lower end portion of the locking portion are in contact with each other. Since the minimum distance in the front-rear direction is smaller than the thickness in the front-rear direction of the bridge portion of the spectacle frame, the bridge portion of the spectacle frame is difficult to be removed from the gap having the interval. On the other hand, when removing the front spectacle frame, the spectacle frame is moved by moving the entire front spectacle frame upward while rotating so that the rear of the front spectacle frame moves upward. The front of the bridge part comes out of the concave groove force of the bridge part body of the front spectacle frame, The bridge part of the spectacle frame abuts the lower end part of the engaging part of the front spectacle frame, and the engaging part is urged toward the rear so that the front and rear of the bridge part main body and the lower end part of the engaging part The gap in the direction is widened, and the bridge portion of the spectacle frame can be easily removed from the gap having the gap.

[0010] As described above, the front spectacle frame according to the present invention 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.

[0011] Preferably, in the invention according to claim 1, the front surface of the lower end portion of the locking portion has a curved shape that curves in a direction in which the bridge portion main body force is separated from the upper side to the lower side.

[0012] According to such a configuration, when the bridge portion of the spectacle frame is inserted into and removed from the gap between the bridge portion main body of the front spectacle frame and the lower end portion of the locking portion, the spectacles are aligned along the curved surface shape. Since the bridge portion of the frame can be moved, there is an advantage that the front eyeglass frame can be smoothly attached and detached.

[0013] In addition, it is possible to adopt a configuration in which the bridge portion of the front spectacle frame according to claim 1 that solves the above problem is inverted upside down. That is, the present invention is a front eyeglass frame that does not include a temple that is detachably attached to the front surface of the eyeglass frame that includes the temple according to claim 3.

BEST MODE FOR CARRYING OUT THE INVENTION

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 in which the spectacle frame force is removed from the front spectacle frame (part of the temple of the spectacle frame is not shown). FIG. 2 is an enlarged view showing a partial cross section of the front spectacle frame according to the present embodiment, and FIG. 2 (a) is an enlarged view taken along the line AA in FIG. 1 (a). Fig. 2 (b) is an enlarged cross-sectional view of the BB arrow in Fig. 1 (b), and Fig. 2 (c) is the state force shown in Fig. 2 (b) when the front spectacle frame is attached to the spectacle frame. ) Shows an enlarged cross-sectional view showing the transition process to the state shown in FIG. 2, and FIG. 2 (d) shows the state force shown in FIG. 2 (a) when the front spectacle frame is removed. Fig. 2 (e) shows a cross-sectional enlarged view showing the transition process to Fig. 1 (a), and Fig. 2 (a) shows an enlarged cross-sectional view taken along the CC line in Fig. 1 (a).

As shown in FIG. 1 or FIG. 2, the front spectacle frame 1 according to the present embodiment is not equipped with a temple, and is detachably attached to the front of the spectacle frame 2 having the temple 21. It is configured to be

[0026] The bridge portion 11 constituting the front spectacle frame 1 includes a bridge portion main body 111 in which a concave groove 11 la 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 a bridge portion main body 111. The upper end force of the recessed groove 111a of the extending portion 112 extending rearward, and the rear end force of the extending portion 112 so as to face the recessed groove 11la in the front-rear direction, are extended downward, and the front-rear direction A flexible member that can be rubbed (in addition to a flexible resin material or metal material, a flexible material may be used as long as it has flexibility) With the locking part 113 I have.

[0027] Then, when the urging force is applied to the locking portion 113, the bridge portion main body 111 and the lower ends of the locking portion 113 are in a state (the state shown in FIGS. 1 (b) and 2 (b)). The minimum distance T1 in the front-rear direction with respect to the portion is set to be 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 between the bottom of the groove 11 la and the locking portion 113 is set. The interval T2 is set substantially equal to the thickness T in the front-rear direction of the bridge portion 22 of the spectacle frame 2.

[0028] With the above configuration, in the state in which the front spectacle frame 1 is attached to the spectacle frame 2 (the state shown in FIGS. 1 (a) and 2 (a)), the front face 22a of the bridge portion of the spectacle frame 2 is attached to the front The extending portion 112 is fitted into the spectacle frame 2 in a state in which the rear surface 22b of the bridge portion of the spectacle frame 2 is engaged with the front surface of the engaging portion 113. The downward force is also supported by the bridge part 22 of this. Therefore, the movement force of the bridge part 11 of the front spectacle frame 1 in the front-rear direction and the downward direction is regulated by the bridge part 22 of the spectacle frame 2, and the front spectacle frame 1 is securely attached to the spectacle frame 2. It is possible.

[0029] When the front spectacle frame 1 is attached to the spectacle frame 2 (see FIG. 2 (c)), the extending portion 112 of the front spectacle frame 1 is disposed above the bridge portion 22 of the spectacle frame 2. Then, the front spectacle frame 1 may be moved downward (in the direction of the arrow in FIG. 2 (c)). As a result, the bridge portion 22 of the ophthalmic frame 2 comes into contact with the lower end portion of the locking portion 113 of the front spectacle frame 1 and the locking portion 113 is rearward (in the direction of the white arrow in FIG. 2 (c)). (The transition from the state shown by the broken line in FIG. 2 (c) to the state shown by the solid line) causes the gap in the front-rear direction between the bridge body 111 and the lower end of the locking part 113 to increase. Thus, the bridge portion 22 of the spectacle frame 2 easily passes through the gap having the interval. Then, after the bridge portion 22 of the spectacle frame 2 passes through the gap, the locking portion 113 returns to its original state (a state where no urging force is applied), and the lower ends of the bridge portion main body 111 and the locking portion 113 are lowered. Since the minimum distance in the front-rear direction with respect to the portion is smaller than the thickness T in the front-rear direction of the bridge portion 22 of the spectacle frame 2, it is 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 removing the front spectacle frame 1 from the spectacle frame 2 (see FIG. 2 (d)), the rear spectacle frame 1 is rotated so that the rear of the front spectacle frame 1 moves upward (FIG. 2 (d) Turn in the direction of the arrow X The front frame 22 of the spectacle frame 2 is moved upward (in the direction of the arrow Y in FIG. 2 (d)) to move the front 22a of the spectacle frame 2 to the bridge portion of the front spectacle frame 1. The bridge 11 of the spectacle frame 2 comes into contact with the lower end of the locking portion 113 of the front spectacle frame 1 and the locking portion 113 is rearward (see FIG. 2 (d)). (In the direction of the white arrow), the bridge body 11 and the lower end of the locking part 113 are swung (transition from the state shown by the broken line in FIG. 2 (d) to the state shown by the solid line). The gap in the front-rear direction is widened, and the bridge portion 22 of the spectacle frame 2 can be easily removed from the gap having the gap.

[0031] As described above, the front spectacle frame 1 according to this embodiment can be easily and reliably attached to the spectacle frame 2 without using magnetic force, and can be easily removed!有する Has excellent advantages.

[0032] Note that in the front spectacle frame 1 according to the present embodiment, as a preferable configuration, the front surface 113a of the lower end portion of the locking portion 113 is curved in a direction away from the bridge portion main body 111 from above to below. It has a curved shape.

[0033] With such a preferable configuration, when the bridge portion 22 of the spectacle frame 2 is inserted into and removed from the gap between the bridge portion main body 111 of the front spectacle frame 1 and the lower end portion of the locking portion 113 (FIG. 2 (c) 2 (d)), the bridge portion 22 of the spectacle frame 2 can be moved along the curved surface shape, and therefore, the front spectacle frame 1 can be smoothly attached and detached. .

[0034] In addition, the front spectacle frame 1 according to the present embodiment preferably has a shape of the front surface of both ends in the left-right direction of the spectacle frame 2 on the rear surface of both ends in the left-right direction of the spectacle frame 1 as a preferred configuration. A concave groove 12 corresponding to is provided.

[0035] With such a preferable configuration, when the front spectacle frame 1 is attached to the spectacle frame 2, the front surfaces of both ends of the spectacle frame 2 engage with the concave groove 12 (see FIG. 2 (e)). Therefore, it is possible to attach the front spectacle frame 1 to the spectacle frame 2 more reliably.

Note that the front spectacle frame according to the present invention is not limited to the above-described configuration. For example, as shown in FIG. It is possible to use.

FIG. 3 is an enlarged view showing a cross section of a bridge portion of a front spectacle frame according to another embodiment of the present invention. The bridge portion 11A shown in FIG. 3A has a configuration in which the bridge portion 11 described with reference to FIG. 2 is turned upside down. More specifically, the bridge portion 11A includes a bridge portion main body 111A in which a concave groove 11lAa 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 a concave portion of the bridge portion main body 111A. Extending part 112A extending backward from the lower end of groove 11 lAa and extending upward from the rear end part of extending part 112A so as to oppose the recessed groove 11 lAa in the front-rear direction, and extending in the front-rear direction The bridge portion main body 111A and the locking portion 113 are in a state where a biasing force acts on the locking portion 113A. The minimum distance T1 in the front-rear direction from the upper end of A is set to be smaller than the thickness T in the front-rear direction of the bridge part 22 of the spectacle frame 2 (see FIG. 2). The distance T2 in the front-rear direction from the stop 113A is set to be approximately equal to the thickness T in the front-rear direction of the bridge part 22 of the spectacle frame 2. It is.

[0038] With respect to the front spectacle frame including the bridge portion 11A according to the present embodiment, the direction of the attaching / detaching operation is reversed up and down from the front spectacle frame 1 including the bridge portion 11 described above. Except for this, it has substantially the same operational effects, and can be easily and securely attached to the spectacle frame 2 without using magnetic force, and can be easily detached. However, since the bridge portion 11A according to the present embodiment is configured to be open at the top, compared to the bridge portion 11 described above, the front spectacle frame is prevented from moving downward due to its own weight. The function is inferior. Therefore, the bridge portion 11A according to the present embodiment is preferably used for a relatively lightweight front spectacle frame.

[0039] The bridge portion 11B shown in FIG. 3 (b) has the groove 11la formed in the bridge portion main body 111 of the bridge portion 11 described with reference to FIG. This is the structure that was formed. More specifically, the bridge portion 11B is opposed to the bridge portion main body 111B, the extended portion 112B in which the upper end portion force of the bridge portion main body 111B extends rearward, and the bridge portion main body 111B. The extending portion 112B extends downward from the rear end portion of the extending portion 112B, and has a locking portion 113B that can be folded in the front-rear direction. Is formed with a concave groove 113Ba corresponding to the shape of the rear surface of the bridge portion 22 of the spectacle frame 2. In the state where the urging force is not applied to the locking portion 113B, the minimum distance T1 between the bridge portion main body 111B and the lower end portion of the locking portion 113B is the front and rear of the bridge portion 22 of the spectacle frame 2. The distance T2 in the front-rear direction between the bottom of the concave groove 113B a and the bridge body 111B is the thickness in the front-rear direction of the bridge part 22 of the spectacle frame 2 while being set smaller than the thickness T in the direction (see FIG. 2). It is set approximately the same as T.

[0040] The front spectacle frame provided with the bridge portion 11B according to the present embodiment also has substantially the same operational effects as the front spectacle frame 1 provided with the bridge portion 11 described above, and does not use magnetic force. It can be easily and securely attached to 2 and can be easily removed.

[0041] The bridge portion 11C shown in FIG. 3 (c) has a configuration in which the bridge portion 11B in FIG. 3 (b) is turned upside down. More specifically, the bridge portion 11C is opposed to the bridge portion main body 111C, the extension portion 112C in which the lower end portion force of the bridge portion main body 111C extends backward, and the bridge portion main body 111C. Thus, the rear end force of the extended portion 112C is also extended upward, and includes a locking portion 113C that is a flexible member force capable of being squeezed in the front-rear direction, and is provided on the front surface of the lower end portion of the locking portion 113C. In the state where the concave groove 113Ca corresponding to the shape of the rear surface of the bridge portion 22 of the spectacle frame 2 is formed, and the biasing force is not acting on the locking portion 113C, the bridge portion main body 11C and the upper end portions 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, while the bottom of the groove 11 3Ca and the bridge body 111C The distance T2 in the front-rear direction is approximately the same as the thickness T in the front-rear direction of the bridge portion 22 of the spectacle frame 2. It is set to equal.

[0042] With respect to 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 portion including the bridge portion 11B. Except for the fact that it is flipped up and down with respect to the hanging spectacle frame, 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 compared to the bridge portion 11 and the bridge portion 11B described above. The function to prevent this will be inferior. Therefore, the bridge part 11C according to the present embodiment is similar to the bridge part 11A described above, It is preferably used for a relatively lightweight front spectacle frame.

[0043] The bridge portion 1 ID shown in FIG. 3 (d) includes a bridge portion main body 111D in which a concave groove 11 IDa 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 a bridge portion main body 111. D groove 11 Da upper end force of IDa is extended to the rear 113Da and the length of the first locking part 113Da is approximately the same as the first groove 113D. 11 includes a second locking portion 113Db extending rearward from the lower end of IDa. At least one of the first locking portion 113Da and the second locking portion 113Db is a flexible member force that can be squeezed in the vertical direction, and the first locking portion 113Da and the second locking portion 113Db. In the state where the urging force is not acting on the locking portion 113Db, the minimum vertical distance HI between the rear end portion of the first locking portion 113Da and the rear end portion of the second locking portion 113Db is On the other hand, the front end portion of the first locking portion 113 Da and the front end portion of the second locking portion 113Db are set smaller than the thickness H (see FIG. 2) of the bridge portion 22 of the spectacle frame 2 in the vertical direction. 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 interval H2 The sum T3 of the length of the front end of the locking portion 113Db and the depth of the concave groove 111Da is set to be approximately equal to the thickness T (see FIG. 2) of the bridge portion 22 of the spectacle frame 2 in the front-rear direction. To have.

[0044] 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 the concave groove of the bridge portion main body 111D of the front spectacle frame. 11 It is fitted into IDa, and 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 upward and downward movement of the bridge portion 11D of the front spectacle frame according to the present embodiment is restricted by the bridge portion 22 of the spectacle frame 2, and the front spectacle frame is used as the spectacle frame 2 It can be securely attached to.

[0045] When the front spectacle frame according to the present embodiment is attached to the spectacle frame 2, the gap between the first engaging portion 113Da and the second engaging portion 113Db of the front spectacle frame 2 After the front spectacle frame is arranged in front of the bridge portion 22, the front spectacle frame is moved backward (rightward in FIG. 2) so that the bridge portion 22 of the spectacle frame 2 becomes the first locking portion of the front spectacle frame. 1 Abuts the lower end of the rear end of 13Da and the upper end of the rear end of the second locking portion 113Db. The rear end portion of the locking portion 113Da is urged upward (when the first locking portion 113Da is made of a flexible material) or the rear end portion of the second locking portion 113Db Is biased downward (when the second locking portion 113Db is made of flexible material), or after both the first locking portion 113Da and the second locking portion 113Db. Since the end portion is cramped (when both the first locking portion 113 Da and the second locking portion 113Db also have flexible material force), the rear end portion of the first locking portion 113Da and the second locking portion The distance in the vertical direction from the rear end of the locking part 113Db is widened, and the bridge part 22 of the spectacle frame 2 passes through the gap having the distance. After the bridge portion 22 of the spectacle frame 2 passes through the gap, the first locking portion 113 Da and / or the second locking portion 113 Db or both of them are in their original states (the urging force is applied). The minimum 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 that of the bridge portion 22 of the spectacle frame 2. Since the thickness is smaller than the thickness H in the vertical direction, the bridge portion 22 of the spectacle frame 2 is difficult to be removed from the gap having the interval.

[0046] On the other hand, when removing the front spectacle frame from the spectacle frame 2, the front spectacle frame 2 is moved forward so that the front surface of the bridge portion 22 of the spectacle frame 2 is the main body of the bridge portion of the front spectacle frame. 11D groove 11Da comes out of IDa, and the bridge portion 22 of the spectacle frame 2 contacts the rear end portion of the first engaging portion 113Da and the second engaging portion 113Db of the front spectacle frame. The first locking portion 113Da is urged and urged upward, or the second locking portion 113Db is urged and urged downward, or Since the rear end portions of both the locking portion 113Da and the second locking portion 113Db are pinched, the upper and lower sides of the rear end portion of the first locking portion 113Da and the rear end portion of the second locking portion 113Db The interval in the direction is widened, and the bridge portion 22 of the spectacle frame 2 is removed from the gap having the interval.

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

[0048] Note that the bridge portion 11, 11A, 11 and 11 described with reference to FIG. 2 and FIG. 3 and the force described only for the configuration in which only the locking portion is a flexible member force. The present invention is not limited to this. The extended portion is also made of a flexible member, and the extended portion and the locking portion are integrally molded. It is also possible to do. In addition, the bridge portion main body may be formed of a flexible member cover, and the pledge portion main body, the extension portion, and the locking portion may be integrally formed. Similarly, for the bridge portion 11D described with reference to FIG. 3, the bridge portion main body 111D also has a flexible member force, and the bridge portion main body 111D, the first locking portions 113Da and Z, or the first The two locking portions 113Db may be formed integrally.

Further, the front spectacle frame according to the present invention is not necessarily limited to a full rim type frame, but can be a single frame type frame in which rims are provided only in the upper half or the lower half.
