Description

  The present invention relates to a connecting structure for connecting two members in a relatively pivotable manner, and in particular, used to connect a lens frame frame armor and a temple, or to jump a rim having a lens from a front frame. It relates to a connecting structure. “Yoroi” means both outer ends of the front frame.

  In a general spectacle frame, an armor and a temple are connected by a hinge. When wearing eyeglasses, the left and right temples can be folded so as to open approximately 90 ° with respect to the front frame, respectively, and when not in use, both temples can be folded on the back side of the front frame. In the spectacle frame, a part of the armor and a part of the temple may form the same function as the hinge without using a commonly used hinge. Thus, a structure corresponding to a hinge is referred to as a “connection structure” in this specification.

  An example of the connection structure described in Patent Document 1 is shown in FIG. In the connection structure 150, one ring-shaped piece 111 is provided on the first member 110, and two ring-shaped pieces 141 and 143 are provided on the second member 140 in parallel. The top 111 has a shaft hole 112 at the center, and the tops 141 and 143 have shaft holes 142 and 144 on the same axis, respectively. A female screw is formed in the shaft hole 144 and is screwed with a shaft screw 145 having a male screw.

  The shaft screw 145 is inserted from the outside of the top 141 in a state where the top 111 is sandwiched between the tops 141 and 143 and the shaft holes 112, 142 and 144 are positioned on the same axis. Then, the first member 110 and the second member 140 are rotatably connected by screwing the shaft screw 145 into the shaft hole 144. When the connection structure 150 is used for a spectacle frame, for example, the first member 110 can be a temple and the second member 140 can be an alloy. Or they can be reversed.

  The spectacle frame is required to have a sliding friction of an appropriate strength for the rotation of the armor and the temple. For example, when the front frame is held by hand, the frictional force is such that the temple does not rotate under its own weight at any angle. In other words, it is preferable that the temple can be opened and closed with a light force and does not open and close unintentionally.

However, if the spectacle frame has been used for many years, the shaft screw 145 rotates together with the top 111 and loosens with the opening and closing of the temple, and the sliding surfaces of the tops 111, 141, and 143 wear out. Dynamic friction gradually decreases. As a result, the glasses may become difficult to use, or the shaft screw 145 may come off and be lost without noticing. And once it loosens, it tends to become loose again even if it tightens again.
Also, a connecting structure used for a spectacle frame of a type in which a rim including a lens is flipped forward from the front frame is required to have a sliding friction with an appropriate strength and has the same problem.

It is a fragmentary sectional view. The connection structure 50 of the present invention is a connection structure that rotatably connects two members constituting the spectacle frame, and the first member 10 and the second member 30 are two sliding plates 20, 20 are connected. Hereinafter, although the case where the 1st member 10 is made into an alloy and the 2nd member 30 is made into a temple is demonstrated, it can apply also to another member. Moreover, although an example in which the first member 10 and the second member 30 are made of metal and the sliding plate 20 is made of resin will be described, these materials and shapes can be changed as appropriate. First, each component will be described, and then FIGS. 1B and 1C will be described.

  FIG. 2 shows the first member 10, where (a) is a schematic plan view and (b) is a schematic side view. The first member 10 includes one ring-shaped piece 11, and a shaft hole 12 is formed at the center of the piece 11. This configuration is exactly the same as the first member 110 in the conventional connection structure 150. Both surfaces of the frame 11 are smoothly formed sliding surfaces 13 and 13. Regarding the distance a (the thickness of the top 11) between the sliding surfaces 13, 13, the relationship with the sliding plate 20 will be described later.

    3 shows the structure of the sliding plate 20, (a) is a schematic side view, (b) is an AA arrow view described in (a), (c) is a BB arrow view, ( d) is a CC arrow view. The sliding plate 20 includes a shaft 23 on an inner side surface 21 serving as a sliding surface, and the shaft 23 is inserted into the shaft hole 12 of the top 11 to serve as a rotating shaft. The shape of the shaft 23 is a short columnar shape, but may be any shape that can rotate with respect to the shaft hole 12, such as a shape in which a part of the column is notched or a polygonal column with rounded corners. You can also.

    The outer surface 22 of the sliding plate 20 is formed with a groove 24 that engages with the clamping portion 31 of the second member 30. The groove 24 does not necessarily have a constant width and depth, but by making these constant, the manufacture of the sliding plate 20 and the assembly of the connecting structure 50 can be simplified. In FIG. 3A, the thickness of the sliding plate 20 (the distance between the inner side surface 21 and the outer side surface 22) is b, and the length of the shaft 23 is c. In (b), the width of the groove 24 is d, and in (d), the distance between the groove bottom 25 and the inner surface 21 is indicated by e.

    The sliding plate 20 can be made of metal, but is preferably made of resin in order to maintain appropriate sliding friction. Among the resins, a resin having high wear resistance is preferable, and for example, polycarbonate, polyamide, polyacetal, polybutylene terephthalate, polyethylene terephthalate, polyphenylene sulfide, polyethersulfone, and the like can be used.

4A and 4B show the second member 30, where FIG. 4A is a schematic plan view, FIG. 4B is a schematic side view, and FIG. The second member 30 includes a clamping portion 31 that clamps the two sliding plates 20. The clamping part 31 is plate-shaped, and can be provided with a long hole-shaped holding part 33 to hold the two sliding plates 20 and the top 11.
Let the width of the holding part 33 be f. Moreover, the clamping part 31 is provided with the insertion port 32 in the edge part, and can insert the two sliding plates 20 and the top | top | piece 11 in the holding | maintenance part 33 from here. Moreover, the clamping part 31 is provided with the elastic part 34 in the back | inner side of the holding | maintenance part 33, and can give moderate clamping force.

    Returning to FIG. 1, the assembly of the connecting structure 50 will be described. As shown in FIGS. 1B and 1C, two sliding plates 20 and 20 are attached to the first member 10. That is, the shaft 23 of the sliding plate 20 is inserted into the shaft hole 12 from both sides of the top 11 of the first member 10. Here, since each sliding plate 20 is lightly fixed to the top 11 and can be easily assembled, it is preferable that the diameters of the shaft 23 and the shaft hole 12 are made substantially equal to form a light fitting state.

    With reference to the cross-sectional view of FIG. 1C, the relationship between the dimensions in a state where two sliding plates 20 are attached to the first member 10 will be described. The relationship between the thickness a of the top 11 shown in FIG. 2B and the length c of the shaft 23 shown in FIG. 3A is a value in which the value of a exceeds twice the value of c (a> 2c). ). This ensures that the inner surface 21 of each sliding plate 20 is in close contact with both sliding surfaces 13 and 13 of the top 11, and an appropriate sliding friction can be obtained.

    As shown in FIG. 1C, when the distance between the outer surfaces 22 of the two sliding plates 20 is A, the value of A is the same as the value of a shown in FIG. It is determined by the value of b shown in a), and A = a + 2b. If the distance between the groove bottoms 25 of the two sliding plates 20 is B, the value of B is determined by the value a shown in FIG. 2B and the value e shown in FIG. B = a + 2e. It should be noted that the width d of the groove 24 of the sliding plate 20 is a dimension with which the clamping portion 31 of the second member 30 can be engaged.

    With the two sliding plates 20 attached to the first member 10, adjustment is made so that the grooves 24 face the same direction. The two sliding plates 20 are slid and held together with the first member 10 by pressing the insertion port 32 of the second member 30 against one end of each groove 24 of the sliding plate 20 and pressing it strongly. It can be located in the part 33. Here, the width f of the holding portion 33 is a value of approximately B, which is slightly smaller than the value of B. As a result, the holding portion 33 applies a clamping force to the sliding plates 20 and 20. Although the clamping part 31 is temporarily expanded at the time of assembly, it can be restored to its original shape by elastic force. By providing the elastic portion 34 on the back side of the holding portion 33, it can be elastically deformed with certainty. The connection structure 50 has a simple structure and can be assembled and disassembled with a single touch.

  FIG. 5 shows, as another example of the present invention, a connection structure 50a according to the present invention including a second member 30a having a different shape. The sandwiching portion 31a is plate-shaped and includes a long-hole-shaped holding portion 33a for holding the two sliding plates 20 and the top 11, and a long-hole-shaped introduction portion 35a that is wider than the holding portion 33a. It has. The width of the holding part 33a is f, and the width of the introduction part 35a is g. And between the holding | maintenance part 33a and the introduction part 35a, the insertion port 32a for inserting the two sliding plates 20 and the top | top 11 into the holding | maintenance part 33a is provided.

  In FIG. 5, the state in which the two sliding plates 20 are attached to the first member 10 is the same as in the case of the connection structure 50. That is, as shown in FIG. 1C, the distance between the outer surfaces 22, 22 of the two sliding plates 20 is A, and the distance between the groove bottoms 25, 25 is B. The width f of the holding portion 33a of the second member 30a is formed in the same manner as the second member 30 described above. The width g of the introduction part 35a is formed to be a large width equal to or greater than A.

  FIGS. 5A to 5C sequentially show the assembly method of the connecting structure 50a, and FIG. 5A shows the first stage in which the first member 10 and the two sliding plates 20 are assembled. . In the second stage of (b), the assembled two sliding plates 20 and the top 11 are positioned in the introduction part 35a of the second member 30a. Since the width g of the introduction part 35a is formed to be A or more, it can be positioned in this way.

    Next, the grooves 24 of the two sliding plates 20 are adjusted so that the grooves 24 face the holding portions 33a, and the ends of the grooves 24 of the sliding plates 20 are brought into contact with the insertion openings 32a and pressed into the holding portions 33a. . The two sliding plates 20 and the top 11 can be slid and moved to the holding portion 33a to be the third stage of (c). Here, the width f of the holding portion 33a is a value of approximately B, which is slightly smaller than the value of B. For this reason, the holding part 33 a gives a clamping force to the sliding plate 20. Although the clamping part 31a is temporarily expanded at the time of assembly, it can be restored to its original shape by elastic force. The introduction part 35a acts in the same manner as the elastic part 34 of the second member 30, and can be reliably elastically deformed. Since the connecting structure 50a has a simple structure, it can be assembled and disassembled with one touch.

  FIG. 6 shows a rimless-type spectacle frame 60 in which the connection structure 50a of the present invention is employed and the armor 61 and the temple 62 are rotatably connected. In this way, the connection structure 50, 50a of the present invention provides a new design that has never existed before. Further, the connection structures 50 and 50a can also be employed in full rim type spectacle frames and half rim type spectacle frames, and the width of these designs can be greatly widened. FIG. 7 shows a half-rim spectacle frame 60a adopting the connecting structure 50b of the present invention when the first member is a temple 62a and the second member is an alloy 61a.

    In the connecting structure of the present invention, sliding friction is generated by sandwiching both sides of the frame with sliding plates. For this reason, it is hard to produce looseness and it can maintain fixed sliding friction. Moreover, even if sliding friction may loosen, if the appropriate tool is used, it can be adjusted so that the width f of the holding parts 31 and 31a becomes narrow. And it can use comfortably, without raise | generating the trouble that a shaft screw falls, like in the conventional connection structure. Moreover, as shown in FIGS. 1-5, a structure is simple and it can manufacture at low cost.

    The connection structure of the present invention is not limited to the above-described form, and can be applied with other forms and many designs. For example, the sliding plate 20 shown in FIG. 3 is not limited to this shape, and may be various types of sliding plates 20x shown in FIGS. Both cases are common in that the inner surface 21 is provided with a shaft 23 and the outer surface 22 is provided with a groove 24. The design of the spectacle frame can be changed by exchanging and using the sliding plates 20x having different shapes. Since the structure is simple, it is possible for the user to replace the sliding plate by himself / herself and to enjoy variations by himself.

    In the connection structure 50 and the connection structure 50a, it has been described that a light fitting state is formed between the shaft hole 12 and the shaft 23 in order to facilitate assembly. FIG. 9 shows another fixing method, in which two sliding plates 20a, 20b are formed so as to form a pair of males and females and are lightly coupled to each other. (A) is a schematic side view which shows both separately, (b) is a schematic side view which shows the state which both couple | bonded.

    That is, the sliding plate 20a includes a fitting projection 28 on the end surface of the shaft 23a, and the sliding plate 20b includes a fitting hole 29 on the end portion of the shaft 23b. In addition, the inner side surfaces 21a and 21b, the outer side surfaces 22a and 22b, and the like are the same as those of the sliding plate 20. Therefore, a fitting state can be formed by the fitting protrusion 28 and the fitting hole 29, and thereby the sliding plates 20 a and 20 b can be fixed to the first member 10.

    As for the second members 30 and 30a, the case of using a plate-like metal material has been shown, but other materials can also be used. FIG. 10 shows a second member 30b formed by bending a rod-shaped material. Similar to the second member 30a of FIG. 5, the clamping portion 31b includes a holding portion 33b and an introduction portion 35b. FIG. 10B is a DD arrow cross-sectional view when a round bar is used, and FIG. 10C is a DD arrow cross-sectional view when a square bar is used.

    FIG. 11 shows the second member 30c when a resin material is used. Also here, the clamping part 31c includes a holding part 33c and an introduction part 33c. As shown in FIG. 11 (b), the sandwiching portion 31 b is increased in thickness so that the cross section is formed in a convex shape, and can thereby be engaged with the groove 24 of the sliding plate 20.

    In the structure of the connection structure of the present invention, other parts can be added, and an example thereof is shown in FIG. The connection structure 50 c is obtained by adding an adjustment plate 80 between the top 11 of the first member 10 and the sliding plate 20. For example, the first member 10 and the sliding plate 20 can be made of metal, and the adjustment plate 80 can be made of resin. With such a configuration, it is possible to maintain the sliding friction in an optimum state by exchanging only the adjustment plate 80 as a consumable item.

    A connection structure 50d shown in FIG. 13 shows an example in which the sliding plate 20d includes a ring-shaped cover 70 on the outer periphery thereof. The cover 70 preferably includes a groove 74 and a groove bottom 75 that match the sliding plate 20. If the shape when the cover 70 is attached to the sliding plate 20 d is the same shape as the sliding plate 20, it can be used in the same manner as the sliding plate 20. Then, by making the cover 70 made of metal, a strong accent can be attached to the tip of the temple. Also, you can change the cover 70 yourself and enjoy the design variations.

    FIG. 14 shows an example in which the connection structure 50e of the present invention is used as a structure for flipping up the rim 66 as a spectacle frame 60e. The eyeglass frame 60e includes a temple 62e at the outer end of the front frame 65. The rim 66 including the lens is not fixed to the front frame 65 but is rotatably connected by a connection structure 50e.

    That is, a mounting hole 67 for attaching the first member 10e is formed at the center of the rim 66. The first member 10 e includes a shaft hole 12 e in the top 11 e and an embedded portion 19 for embedding in the attachment hole 67. Further, a rim attachment portion 68 is formed at the center portion of the front frame 65, and the second member 30e can be attached. The second member 30e includes a holding portion 33e and an insertion port 32e. And the 1st member 10e and the 2nd member 30e can comprise the connection structure 50e of this invention by connecting via the sliding plate 20. FIG.

    For this reason, the spectacle frame 60e can jump the rim 66 provided with a lens forward from the front frame 65. For example, a user who is reading while wearing glasses normally can flip up the rim 66 forward when he / she wants to take off the glasses a little, so that the user can easily remove the glasses. be able to.

    As described above, the connection structure 50 of the present invention can give the first member 10, the sliding plate 20, and the second member 30 many changes, and give a large width to the design of the spectacle frame. be able to.
