Alternatively, as shown in FIG. 9, it may not be provided in a facing state such as being provided at an angular pitch of 120 degrees.
【0027】 前記各連結具において、筒部材に設けた挿入孔は、筒部の他端で開口するよ うに設けられてもよい。この場合は、軸部材の軸部を比較的長く形成しておくこ とにより、この軸部を、該挿入孔の他端開口より突出させることができる。この ようにすると、連結すべき眼鏡部材の肉厚が異なる場合においても、同一の連結 具を用いて連結できる利点がある。In each of the connecting tools, the insertion hole provided in the tubular member may be provided so as to open at the other end of the tubular portion. In this case, by forming the shaft portion of the shaft member to be relatively long, the shaft portion can be made to protrude from the other end opening of the insertion hole. In this way, even if the eyeglass members to be connected have different wall thicknesses, there is an advantage that they can be connected using the same connecting tool.
【0028】 これを、レンズ19とテンプルの連結部17aとを連結する場合を例にとって 説明する。レンズ19が厚肉の場合には、図10に示すように、軸部10が筒部 4の他端開口45より突出しないが、レンズ19が薄肉の場合には、図11に示 すように、軸部10の先端部分46が挿入孔の他端開口45より突出する場合が 生ずる。この場合は、突出した部分を適宜切除する。This will be described by taking as an example the case where the lens 19 and the temple connecting portion 17a are connected. When the lens 19 is thick, as shown in FIG. 10, the shaft portion 10 does not protrude from the other end opening 45 of the tubular portion 4, but when the lens 19 is thin, as shown in FIG. In some cases, the tip portion 46 of the shaft portion 10 projects from the other end opening 45 of the insertion hole. In this case, the protruding portion is appropriately cut off.
【0029】 筒部の外形は先細化するように形成することができる。図12は、その場合 の一例を示すものであり、例えばテンプルの連結部17aとレンズ19とを連結 する場合に応用されており、レンズには、筒部の外形の縮小形態に合わせて、外 端から内端に向けて稍細くなる挿通孔47が設けられている。挿入孔6に軸部1 0が押入されて、筒部の割溝間の部分25が押し拡げられ、筒部の外面49が角 孔の内周面26に押圧状態となっている。そして、弾性パッキン材15を稍圧縮 させ、筒部側の第1の係合部と軸部側の第2の係合部との最後の係合が行われて おり、該弾性パッキンの弾性復元作用によって、両係合部の係合状態が安定的に 保持されている。The outer shape of the tubular portion can be formed so as to be tapered. FIG. 12 shows an example of such a case, and is applied, for example, to the case where the temple connecting portion 17a and the lens 19 are connected to each other. An insertion hole 47 is provided which is tapered from the end toward the inner end. The shaft portion 10 is pushed into the insertion hole 6, the portion 25 between the split grooves of the cylindrical portion is expanded, and the outer surface 49 of the cylindrical portion is pressed against the inner peripheral surface 26 of the square hole. Then, the elastic packing material 15 is slightly compressed, and the first engagement portion on the tubular portion side and the second engagement portion on the shaft portion side are finally engaged, and the elastic restoration of the elastic packing is performed. By the action, the engaged state of both engaging portions is stably maintained.
【0030】 筒部の外形をこのように先細に形成し、又眼鏡部材にもそれに合わせて先細の 挿通孔を設けると、該挿通孔への筒部の挿入が容易となって好ましい。It is preferable that the outer shape of the cylindrical portion is formed in such a taper shape and that the eyeglass member is also provided with a tapered insertion hole so that the cylindrical portion can be easily inserted into the insertion hole.
【0031】 本考案に係る連結具において、軸部材は金属を以て成形されることもある。In the connector according to the present invention, the shaft member may be made of metal.
【0032】[0032]
本考案は以上のように構成しているため、以下の如き優れた効果を奏する。 連結すべき眼鏡部材の連通する挿通孔にその一端より筒部材の筒部を挿入し て後、該連通孔の他端側より、筒部の挿入孔に軸部を押入して、該軸部の第2の 係合部と筒部の第1の係合部とを係合させ、弾性パッキン材を稍圧縮状態にして 最後の係合を行うと、眼鏡部材相互を、緩みが発生しない安定状態に連結するこ とができる。 Since the present invention is configured as described above, it has the following excellent effects. After inserting the tubular part of the tubular member from one end into the communicating hole of the eyeglass member to be connected, push the shaft part into the insertion hole of the tubular part from the other end side of the communicating hole to insert the shaft part. By engaging the second engaging portion of the above and the first engaging portion of the tubular portion and making the elastic packing material into the slightly compressed state for the final engagement, the eyeglass members are not loosened and stable. Can be linked to states.
【0033】 本考案に係る連結具によるときは、筒部に軸部を押入するというワンタッチ 操作によって眼鏡部材相互を容易に連結できるため、従来のようにナットやビス を何回も回転操作しなければならない不都合がなく、連結作業の能率化を期しう る。In the case of the connecting device according to the present invention, the eyeglass members can be easily connected to each other by a one-touch operation of pushing the shaft portion into the tubular portion, so that the nut and the screw must be rotated many times as in the conventional case. There is no inconvenience that must be made, and we will strive to streamline the connection work.
【0034】 挿入孔を、筒部の他端側においても開口させることにより、軸部材の軸部が 該他端開口より突出することが許容される。そのため、連結されるべき眼鏡部材 の肉厚が多少異なる場合であっても同一の連結具を以て応ずることができ、汎用 性向上を期しうる。By opening the insertion hole also on the other end side of the tubular portion, the shaft portion of the shaft member is allowed to protrude from the other end opening. Therefore, even if the thickness of the eyeglass members to be connected is slightly different, the same connecting tool can be used and the versatility can be improved.
【0035】 筒部材が樹脂製のものであるため、樹脂製レンズをテンプルの連結部に連結 する場合等、割れやすい素材からなる眼鏡部材を連結する場合、適度のクッショ ン作用が発揮される。そのため、例えば図13に示したようなブシュdを省略し て眼鏡部材相互を連結することが可能となり、経済的である。Since the tubular member is made of resin, an appropriate cushioning effect is exhibited when the eyeglass member made of a material that is easily broken, such as when connecting the resin lens to the connecting portion of the temple, is connected. Therefore, it becomes possible to connect the eyeglass members to each other by omitting the bush d as shown in FIG. 13, which is economical.
