Description
【０００１】[0001]
本考案はメガネフレームのツルを屈曲自在に連結する屈曲継手に関するもので ある。 The present invention relates to a bending joint for flexibly connecting a temple of an eyeglass frame.
【０００２】[0002]
メガネフレームにはその両サイドにヨロイが設けられ、該ヨロイには蝶番を介 してツルが連結し、ツルは折り畳み可能な構造となっている。勿論、蝶番継手で なく他の屈曲継手構造となっている場合もあるが、メガネフレームとしてのデザ インが損なわれないように上記屈曲継手は比較的小さくなっている。すなわち小 さい蝶番などの屈曲継手でもって長いツルを連結している。したがって、ツルを 折り畳む際に作用する力は該屈曲継手に無理を強いることになり、メガネを購入 して暫くすればツルにガタ付を生じる結果となる。 The spectacle frame is provided with a royer on both sides thereof, and a vine is connected to the trolley via a hinge, and the vine has a foldable structure. Of course, there may be other bending joint structures instead of hinge joints, but the bending joint is relatively small so that the design of the eyeglass frame is not impaired. In other words, a long hinge is connected with a bending joint such as a small hinge. Therefore, the force that acts when the vine is folded imposes a force on the bending joint, and if the glasses are purchased for a while, the vine will rattle.
【０００３】 このようにツルにガタ付きが生じた場合には、該屈曲継手が蝶番であればビス を増し締めしてガタ付きを無くしているが、該ビスの増し締めを時々しなければ ならなくなる。これは、蝶番軸となるビスがツルの折り畳み操作に伴って僅かづ つ緩む為であり、また接触して摺り合う摺動面が摩耗する為でもある。ツルがガ タ付くようになれば、折り畳んだ際の該ツルは安定せず、メガネを着用した場合 に該メガネは位置ズレを生じ、時には顔から外れて落下するといったこともある 。When rattling occurs in the temple in this way, if the bending joint is a hinge, the screw is tightened to eliminate the rattling, but the screw must be tightened occasionally. Disappear. This is because the screw that serves as the hinge shaft loosens slightly as the vine is folded, and the sliding surfaces that come into contact with and slide against each other wear. If the vine becomes loose, the vine will not be stable when folded, and the spectacles will be misaligned when the spectacles are worn and sometimes fall off the face.
【０００４】[0004]
このように従来のメガネフレーム用ツルの屈曲継手構造には上記のごとき問題 がある。本考案が解決しようとする課題はこれら問題点であり、長期間使用して もガタ付くことなく耐久性の高いツルの屈曲継手構造を提供する。 As described above, the conventional bending joint structure of a temple for eyeglass frames has the above problems. The problems to be solved by the present invention are these problems, and provide a bending joint structure of a crane which has high durability without rattling even after long-term use.
【０００５】[0005]
【課題を解決するための手段】 本考案に係るツルの屈曲継手構造はスプライン型式に構成したものであり、軸 の外側面並びに軸受けの内側面は凹凸面を形成している。該凹面と凸面は互いに 噛み合っており、また凹面と凸面は接触していて、ツルを折り畳む際には該凹凸 面は僅かな圧縮変形を繰り返しして摺り合わせ摺動する。すなわち、軸受け孔及 び軸のいずれか一方の凹部に他方の凸部が噛み合った状態にあり、該凸部は圧縮 変形して潰されて移動し、隣接する凹部に再び噛み合う。[Means for Solving the Problems] The bending joint structure of a crane according to the present invention is constructed in a spline type, and the outer surface of the shaft and the inner surface of the bearing have uneven surfaces. The concave surface and the convex surface are in mesh with each other, and the concave surface and the convex surface are in contact with each other, and when the temple is folded, the uneven surface repeats slight compression deformation and slides by sliding. That is, one of the recesses of the bearing hole and the shaft is in mesh with the other projection, and the projection is compressed and deformed, crushed and moved, and again meshes with the adjacent recess.
【０００６】 勿論、上記凹凸面の凹部と凸部の度合いは噛み合い位置を変え得る大きさとし ており、凸部は凹部の底まで達しておらず、少なくとも片方の凸部は比較的滑ら かな曲面にて形成されている。ツルがガタ付かないように連結される為には、上 記の通り、接触する凹凸面間に隙間があってはならず、またツルが折り畳まれる ように軸受け又は軸は回転しなければならない為に、凸部は圧縮変形する性質を 有し、そのために軸又は軸受けのいずれか一方は樹脂製となっている。しかも該 樹脂は耐摩耗性に優れた性質を有す。Of course, the degree of the concave and convex portions on the uneven surface is such that the meshing position can be changed. The convex portion does not reach the bottom of the concave portion, and at least one convex portion has a relatively smooth curved surface. Is formed. In order for the crane to be connected so that it does not rattle, as described above, there must be no gap between the contacting uneven surfaces, and the bearing or shaft must rotate so that the crane can be folded. In addition, the convex portion has a property of being compressed and deformed, so that either the shaft or the bearing is made of resin. Moreover, the resin has excellent wear resistance.
【０００７】[0007]
メガネフレームのツルをこのような構造で連結する場合、ツルは軸並びに軸受 けに形成した凹凸のピッチに相当する角度づつ断続的に屈曲する。そして折り畳 まれたツルはひとりでに開くことはなく、ツルは安定して折り畳まれ、着用した メガネがガタ付くことはない。軸並びに軸受けは耐摩耗性の高い樹脂が用いられ るが、軸受けを金属とし、一方の軸を樹脂製とすることで軸側を摩耗させ、ある 程度摩耗したところで軸を交換可能な構造とすることが出来る。以下、本考案に 係る実施例を図面に基づいて詳細に説明する。 When the temples of the spectacle frame are connected by such a structure, the temples are intermittently bent at an angle corresponding to the pitch of the unevenness formed on the shaft and the bearing. And the folded vine does not open by itself, the vine is stably folded, and the worn glasses do not rattle. The shafts and bearings are made of resin with high wear resistance, but the bearings are made of metal, and one of the shafts is made of resin so that the shaft side is worn, and the shaft can be replaced after a certain amount of wear. You can Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
【０００８】[0008]
図１は本考案に係るツルの屈曲継手構造の外観を示しており、１はツル、２は ヨロイを表し、該ツル１はヨロイ２に屈曲可能に連結している。ここで、ヨロイ ２はレンズ３にビス止めにて取着されているが、フレームの形態は限定せず、樹 脂製フレームであっても金属製フレームであってもよい。勿論、ツル１の材質も 限定はしない。 FIG. 1 shows the appearance of a bending joint structure of a vine according to the present invention, where 1 is a vine and 2 is an endowment, and the vine 1 is flexibly connected to an endowment 2. Here, the armor 2 is attached to the lens 3 with screws, but the form of the frame is not limited, and it may be a resin frame or a metal frame. Of course, the material of the vine 1 is not limited.
【０００９】 図２はヨロイ２の継手部を表した詳細図である。同図はヨロイ２の内側を示し ているが、先端部には支持片４ａ，４ｂを所定の間隔をおいて形成し、該支持片 ４ａ，４ｂには軸孔５が上下方向に貫通している。また、上方の支持片４ａの上 面には軸孔５より大径の凹溝６が形成され、両支持片４ａ，４ｂ間は空間７とな っている。そして図３はツル１の継手部を表した詳細図であり、該ツル端には軸 受け８が突出して設けられ、該軸受け８の中心には上下方向に軸孔９が形成され ている。この軸孔９の内面は同図に示すごとくスプラインのような凹凸面となっ ている。FIG. 2 is a detailed view showing a joint portion of the armor 2. Although the drawing shows the inside of the end piece 2, support pieces 4a, 4b are formed at a predetermined interval at the tip end, and a shaft hole 5 is vertically penetrated through the support pieces 4a, 4b. There is. Further, a groove 6 having a diameter larger than that of the shaft hole 5 is formed on the upper surface of the upper support piece 4a, and a space 7 is formed between both support pieces 4a and 4b. FIG. 3 is a detailed view showing the joint portion of the temple 1. A bearing 8 is provided so as to project from the temple end, and a shaft hole 9 is formed in the vertical direction at the center of the bearing 8. The inner surface of the shaft hole 9 is an uneven surface such as a spline as shown in FIG.
【００１０】 図４はヨロイ２とツル１を連結する軸１０であって、該軸１０は大径のツバ１ １、スプライン軸部１２、及びツメ部１３から成っている。ツル１の軸受け８を ヨロイ２の両支持片４ａ，４ｂ間に形成した空間７に嵌入し、その状態で該軸１ ０を軸孔５、９に挿通する。またツバ１０は支持片４ａの凹溝６に嵌入する。そ してスプライン軸部１２の下端には凸片１４、１４を突出して形成し、該凸片１ ４、１４は支持片４ｂに設けた凹部１５、１５に嵌合する。したがって、軸１０ は両支持片４ａ，４ｂに回り止めされて取着され、更にツメ部１３が支持片４ｂ の下面に当てがった部品に係止して外れないような構造と成っている。また該ツ メ部１３が嵌着し易いように溝１９を形成したり、該ツメ部１３に代わってネジ 部を設けてナット締めすることも出来る。FIG. 4 shows a shaft 10 which connects the end pieces 2 and the temple 1, and the shaft 10 is composed of a large-diameter collar 11, a spline shaft portion 12, and a tab portion 13. The bearing 8 of the temple 1 is fitted into the space 7 formed between the support pieces 4a and 4b of the armature 2, and the shaft 10 is inserted into the shaft holes 5 and 9 in this state. Further, the brim 10 is fitted into the concave groove 6 of the support piece 4a. Then, projecting pieces 14 and 14 are formed at the lower end of the spline shaft portion 12 so as to project, and the projecting pieces 14 and 14 are fitted into the recessed portions 15 and 15 provided in the support piece 4b. Therefore, the shaft 10 is attached to the support pieces 4a and 4b while being prevented from being rotated, and the claw portion 13 is locked to a component applied to the lower surface of the support piece 4b so as not to come off. . Further, the groove 19 may be formed so that the claw portion 13 can be easily fitted, or a screw portion may be provided in place of the claw portion 13 to tighten the nut.
【００１１】 図５は軸孔９に軸１０が嵌入した状態である。軸孔９の内面は凹凸面と成って おり、一定ピッチで凸部１６、１６…が軸方向に形成され、凸部１６、１６…の 間に形成される凹部１７、１７…には軸１０の側面に形成した凸部１８、１８… が嵌入している。軸孔９の凸部１６は三角形断面をなしているが、軸１０の凸部 １８は滑らかな曲面を形成している。したがって凹部１７に嵌入した凸部１８は 、凹部１７の底に空間を残している。FIG. 5 shows a state in which the shaft 10 is fitted in the shaft hole 9. The inner surface of the shaft hole 9 is a concave-convex surface, the convex portions 16, 16 ... Are formed in the axial direction at a constant pitch, and the concave portion 17, 17 formed between the convex portions 16, 16 ... The protrusions 18, 18 ... Formed on the side surfaces of the are fitted. The convex portion 16 of the shaft hole 9 has a triangular cross section, while the convex portion 18 of the shaft 10 forms a smooth curved surface. Therefore, the convex portion 18 fitted in the concave portion 17 leaves a space at the bottom of the concave portion 17.
【００１２】 スプライン軸部１２は軸孔９の凸部１６、１６…との間に隙間を残さず、むし ろ僅かに圧縮された状態で嵌入し、固定された軸１０を中心として軸受け８が回 転する。この際、軸孔９の凸部１６は軸１０の凸部１８を乗り上げねばならず、 これら凸部１６…、１８…は僅かに圧縮変形する。勿論、軸受け８及び軸１０は 耐摩耗性に優れた樹脂製であって、ある程度の圧縮変形は可能とする。ただし、 時にはいずれか一方のみを金属製とすることが出来、例えば軸受け８を金属製と し、軸１０を樹脂製とする。そして樹脂製の軸１０が摩耗した場合には軸１０の み交換する。The spline shaft portion 12 is fitted in a slightly compressed state without leaving a gap between the spline shaft portion 9 and the convex portions 16, 16 ... Of the shaft hole 9, and the bearing 8 is centered around the fixed shaft 10. Rotate. At this time, the convex portion 16 of the shaft hole 9 must ride on the convex portion 18 of the shaft 10, and the convex portions 16 ..., 18 ... Are slightly compressed and deformed. Of course, the bearing 8 and the shaft 10 are made of resin having excellent wear resistance, and can be compressed and deformed to some extent. However, sometimes only one of them can be made of metal, for example, the bearing 8 is made of metal and the shaft 10 is made of resin. When the resin shaft 10 is worn, only the shaft 10 is replaced.
【００１３】 ところで、上記軸１０の取着形態は色々あって、ツメ部１３の代わりにネジ部 を形成してナット締めすることもあり、また軸孔５に圧入するだけで該軸孔５か ら抜けないようにすることも出来る。一方、軸孔９の凹凸部１７…、１６…及び スプライン軸部１２の凸部１８…のみを別部品として成形し、軸受け８及び軸１ ０に取付け・固定することもある。By the way, there are various attachment forms of the shaft 10, and a screw part may be formed instead of the claw part 13 and a nut may be tightened. You can prevent it from coming off. On the other hand, only the concavo-convex portions 17 ..., 16 of the shaft hole 9 and the convex portions 18 of the spline shaft portion 12 may be molded as separate parts and attached / fixed to the bearing 8 and the shaft 10.
【００１４】 更に上記実施例では軸１０を回転しないように固定しているが、該軸をツル１ の軸受け側に固定して該ツル１の折り畳みとともに回動させることも出来る。し たがって、この場合には軸受け８の軸孔９の内側面には凹凸部を必要とせず、ヨ ロイ２の支持片４ａ，４ｂの軸孔５に凹凸部を形成してスプライン軸孔とする。 以上述べたように、本考案に係るツルの継手構造は軸及び軸孔に凹凸部を形成し たものであり、次のような効果を得ることが出来る。Further, although the shaft 10 is fixed so as not to rotate in the above-described embodiment, the shaft may be fixed to the bearing side of the temple 1 and rotated together with the folding of the temple 1. Therefore, in this case, no concavo-convex portion is required on the inner side surface of the shaft hole 9 of the bearing 8, and the concavo-convex portion is formed on the shaft holes 5 of the supporting pieces 4a and 4b of the endless rod 2 to form the spline shaft hole. To do. As described above, the vine joint structure according to the present invention has the shaft and the shaft hole formed with the concavo-convex portion, and the following effects can be obtained.
【００１５】[0015]
本考案のツル継手は軸及び軸孔の側面に凹凸部を連続して形成し、互いに噛み 合わせたものであって、ツルのガタ付きは解消されて安定した耐久性のある継手 構造と成る。ツルを折り畳む場合には上記凹凸部が圧縮変形して隣接する凹凸部 に断続的に噛み合い、ツルはひとりでに開くことはなく、また着用したメガネは 位置ズレすることなく安定する。 The vine joint of the present invention is one in which the shaft and the side surface of the shaft hole are formed with concavo-convex portions continuously and meshed with each other, and the rattling of the vine is eliminated to provide a stable and durable joint structure. When the temple is folded, the uneven portion is compressed and deformed and meshes with the adjacent uneven portion intermittently, the vine is not opened by itself, and the worn glasses are stable without being displaced.
