Description

【考案の詳細な説明】 本考案は、時計バンドの駒の接続構造に関する。[Detailed explanation of the idea] The present invention relates to a connection structure for pieces of a watch band.

時計バンドの駒の接続構造の従来例として、第１図に示
すものがある。A conventional example of a connection structure for pieces of a watch band is shown in FIG.

駒１は長手方向に凸部１ａと凹部１ｂとを備え、隣接す
る駒２と噛合している。The piece 1 includes a convex portion 1a and a concave portion 1b in the longitudinal direction, and meshes with an adjacent piece 2.

駒１の凸部１ａとこれに噛合する凹部２ｂとを横通して
ネジピン３が配設されている。A screw pin 3 is disposed so as to pass through the convex portion 1a of the piece 1 and the concave portion 2b that meshes with the convex portion 1a.

ネジピン３は凹部２ｂに螺着され、バンド全体の長さを
調節する場合に、頭部にあるドライバー溝３ａを回転し
て駒より係脱される。The screw pin 3 is screwed into the recess 2b, and when adjusting the length of the entire band, it is engaged and detached from the piece by rotating the driver groove 3a in the head.

この構造は、ネジによる駒の連結を基本としているため
、取り扱いが容易で且つ確実に行なえる利点を有してい
る反面、下記の２つの理由による問題を抱えている。This structure is based on connecting the pieces with screws, and has the advantage of being easy and reliable to handle, but has problems due to the following two reasons.

先ず、第１の理由は、バンドの表面にメッキや塗装を施
す場合、駒２とネジピン３とにメッキ膜や塗装膜が形成
されてしまうことがある。The first reason is that when plating or painting the surface of the band, a plating film or a paint film may be formed on the pieces 2 and screw pins 3.

つまり、ネジピン３を回転する必要が生じた場合に、ネ
ジ回し溝がメッキ膜によって浅・くなり、ネジピン、３
を動かすことができない事態が発生し、商品化に支障を
きたす。In other words, when it is necessary to rotate the screw pin 3, the screwdriver groove becomes shallow due to the plating film, and the screw pin 3
A situation occurs where the product cannot be moved, which hinders commercialization.

また、第２の理由は、長期間に亘ってこの種のバンドを
使用した場合、駒の凸部１ａと凹部２ｂとの回動によっ
て、ネジピン３が緩み、駒２から外れてしまうことであ
る。The second reason is that when this type of band is used for a long period of time, the screw pin 3 becomes loosened and comes off from the piece 2 due to the rotation between the convex portion 1a and the concave portion 2b of the piece.

特に、塗装やメッキを施したものでなく、メッキ等の必
要のないステンレス鋼のバンドにこの問題が発生する。This problem particularly occurs with stainless steel bands that are not painted or plated and do not require plating.

以上、述べた如く本考案は、上記問題点を解決すべく、
駒の凸部と隣接する凹部の両端に横通ずる貫通穴を各々
設けると共に、該貫通穴の外側端部に該貫通穴より外径

うとするものである。As mentioned above, the present invention aims to solve the above problems.
A through-hole is provided at both ends of the recess adjacent to the convex part of the piece, and a bottomed hole with an outer diameter larger than that of the through-hole is provided at the outer end of the through-hole, and at least one end of the green glaze is A C-shaped stopper member having a slightly larger outer diameter than the through-hole and whose internal part protruding partially inward contacts the bottom of the circumferential groove is attached to the circumferential groove to connect the pieces. The objective is to provide a piece structure in which the raw glaze can be easily attached and detached, and the raw glaze does not come off unexpectedly.

以下、本考案の実施例を図面により説明する。Embodiments of the present invention will be described below with reference to the drawings.

第２図乃至第５図は本考案の実施例を示し、第２図はバ

、第５図は止め部材の平面図、である。2 to 5 show an embodiment of the present invention, FIG. 2 is a partial sectional view of the band, FIGS. 3 and 4 are enlarged sectional views of the main parts, and FIG. 5 is a plan view of the stopper member. It is.

駒４はバンド長手方向に凸部４ａと凹部４ｂとを備え、
隣接する駒５と相互に組合さってバンドを構成している
。The piece 4 includes a convex portion 4a and a concave portion 4b in the longitudinal direction of the band,
The pieces are mutually combined with adjacent pieces 5 to form a band.

駒の凸部４ａと隣接する凹部５ｂとの間には一軸上の貫
通穴６が設けられ、この貫通穴６の両端部、即ち、凹部
を形づくっている駒部には、貫通穴６より外径部の有底
穴７が設けられている。A uniaxial through hole 6 is provided between the protrusion 4a of the piece and the adjacent recess 5b, and both ends of the through hole 6, that is, the piece forming the recess, has an outer diameter larger than that of the through hole 6. A bottomed hole 7 is provided at the bottom.

貫通穴６の穴径は後述の生釉８よりやや径大であり、有
底穴７は止め部材９よりやや径大か同径である。The diameter of the through hole 6 is slightly larger than that of the raw glaze 8 described later, and the bottomed hole 7 is slightly larger than or the same diameter as the stop member 9.

又、有底穴の深さは生釉８の外端から止め部材９の内側
迄の距離より大きい。Further, the depth of the bottomed hole is greater than the distance from the outer end of the green glaze 8 to the inner side of the stopper member 9.

次に、生釉８は両端部に周状溝８ａを有し、この周状溝
に平面、Ｃ形の止め部材９を弾着している。Next, the raw glaze 8 has a circumferential groove 8a at both ends, and a flat, C-shaped stopper member 9 is fitted into the circumferential groove.

止め部材９の外径は貫通穴６の穴径より大きく形成され
、通常、第３図の如く、間隙Ｓを保持した状態で周状ｉ
８ａに配設され、部分的に内側に突出した内接部９ａは
周状溝８ａの底に接して、止め部材９が生釉８に同心的
に配列されるようになっており、止め部材９の外径部が
生釉８の外径部から全周に亘って均一にはみ出している
。The outer diameter of the stopper member 9 is formed to be larger than the hole diameter of the through hole 6, and normally, as shown in FIG.
8a, an inscribed portion 9a that partially protrudes inward is in contact with the bottom of the circumferential groove 8a, so that the stopper members 9 are arranged concentrically with the raw glaze 8, and the stopper members The outer diameter portion of 9 uniformly protrudes from the outer diameter portion of raw glaze 8 over the entire circumference.

そして、止め部材９が貫通穴６に通過中に、止め部材９
は間隙Ｓを利用して内方に弾性変形し、通過を可能にす
る。Then, while the stopper member 9 is passing through the through hole 6, the stopper member 9
is elastically deformed inward using the gap S to enable passage.

第５図はその止め部材９の平面図であり、周状溝８ａの
底と、止め部材９の内接部９ａが接して、周状溝の底と
同じに配列されている。FIG. 5 is a plan view of the stop member 9, in which the bottom of the circumferential groove 8a and the inner part 9a of the stop member 9 are in contact with each other and are arranged in the same manner as the bottom of the circumferential groove.

次に、生釉の係脱について説明する。Next, we will explain how to attach and detach the raw glaze.

先ず、駒４と隣接の駒５とを、凸部４ａと凹部５ｂとが
噛合する状態で組合せる。First, the piece 4 and the adjacent piece 5 are assembled with the convex part 4a and the concave part 5b meshing with each other.

次に、止め部材９を弾着した生釉８を一方の有底穴７よ
り弾入する。Next, the raw glaze 8 with the stopper 9 attached is inserted through one of the bottomed holes 7.

有底穴の底には斜面５Ｃが設けられているので、この斜
面５Ｃの働きにより、第４図に示す如く、止め部材９が
内方に弾性変形を生じ、貫通穴６を通過することができ
る。Since a slope 5C is provided at the bottom of the bottomed hole, the function of the slope 5C causes the stop member 9 to elastically deform inward as shown in FIG. 4, thereby preventing it from passing through the through hole 6. can.

そして、他方の有底穴７に到達したとき、止め部材９が
復元して、生釉の取り付けを完了する。Then, when the other bottomed hole 7 is reached, the stopper member 9 is restored and the installation of the raw glaze is completed.

生釉の取り外しは、生釉８の端部を強く押してやると、
取り付けのときと同様に、止め部材９が弾性変形して、
貫通穴６から取り出すことができる。To remove the raw glaze, press the edge of the raw glaze 8 firmly.
As in the case of installation, the stopper member 9 is elastically deformed,
It can be taken out from the through hole 6.

尚、駒の形状は、第６図に示す如く、複数の凹部５ｂと
凸部４ａとで構成したものでもよく、駒の接続構造は、
本考案の第２図と同様である。The shape of the piece may be composed of a plurality of concave portions 5b and convex portions 4a as shown in FIG. 6, and the connection structure of the piece is as follows.
It is similar to FIG. 2 of the present invention.

（接続構造は省略） 第７図は本考案の更に他の実施例を示し、生釉８の一端
につば部８ｂを設け、他端に前記した止め部材９を弾着
したものである。(Connection structure is omitted) FIG. 7 shows still another embodiment of the present invention, in which a collar portion 8b is provided at one end of the raw glaze 8, and the aforementioned stop member 9 is snapped onto the other end.

以上、述べた如く、本考案は、少なくとも一方の駒端部
の周状溝にＣ形止め部材を装着した生釉を貫通穴に挿入
したので、生釉の係脱がきわめて容易で、且つ確実であ
り、従来のネジピンによる駒連結の場合、バンド使用中
にネジピンがゆるんで不意に外れてバンドが分離するこ
ともなく、メッキや塗装で生釉の端部が駒と一体につな
がっても、生釉を押せば簡単に押し出すことができ、従
来の問題を回避することができる。As described above, in the present invention, the raw glaze with a C-shaped stopper attached to the circumferential groove at at least one end of the piece is inserted into the through hole, so the engagement and removal of the raw glaze is extremely easy and reliable. Yes, when connecting pieces using conventional screw pins, the screw pins do not loosen and come off unexpectedly while the band is in use, and the band does not separate. The glaze can be easily extruded by pressing it, avoiding the traditional problems.

更に、止め部材は、部分的に内側に突出した内接部を生
釉の周状溝の底に接しているので、調心作用が発生し、
貫通穴との引掛りが全周に亘って平均的におこなわれ、
安定した掛止状態を維持でき、また止め部材を係脱する
ときも、止め部材が生釉に対して片寄らず操作性にすぐ
れている。Furthermore, since the stop member has an inwardly protruding partially inwardly-contacted part in contact with the bottom of the circumferential groove of the unglazed glaze, an alignment effect occurs.
The hooking with the through hole is done evenly over the entire circumference,
A stable locking state can be maintained, and even when the locking member is engaged or detached, the locking member does not shift toward the raw glaze, resulting in excellent operability.
