WRISTWATCH AND STRAP FOR TIMEPIECE

Abstract

To provide a wristwatch capable of promoting operability of attaching and detaching an end-piece to and from a rod leg and capable of promoting handling performance in being brought to and from a storing place. A recess portion is formed at a back face of an end-piece of a strap. Through holes opposed to attaching holes of rod legs are respectively provided at side walls of the piece in a state of receiving the piece at a rod crotch between the rod leg of a case body continuous to each other. An attaching member including a fold back portion having pinching portions and capable of being elastically deformed in directions of increasing and reducing an interval therebetween and attaching shaft portions folded to bend from the two portions to be rotatably inserted into the holes is contained in a recess portion movably between a first position and a second position. A fixed shaft pinched by the portion when the member is arranged at the first position is provided at the recess portion to be shifted from a linear line connecting the through holes. The shaft portions are projected to outside of the piece by widening an interval between the portions by the shaft at the first position, and the shaft portions are immersed into the piece when the member is arranged at the second position by detaching the fold back portion from the shaft.

Claims

1. A wristwatch comprising: a case body projected with rod legs having attaching holes and formed with a rod crotch between the contiguous rod legs; anda strap being attachably and detachably connected to the case;wherein a recess portion is formed at a back face of an end-piece of the strap received by the rod crotch to be able to be brought thereto and therefrom;wherein through holes opposed to the attaching holes are respectively provided at side walls of the end-piece disposed on both sides of the recess portion in a state of receiving the end-piece at the rod crotch;wherein an attaching member including a fold back portion having pinching portions opposed to each other and capable of being deformed elastically in a direction of widening and a direction of narrowing an interval between the pinching portions and attaching shaft portions rotatably inserted into the through holes by being folded to bend from the two pinching portions in directions of being remote from each other is contained at the recess portion movably between a first position and a second position by rotating the attaching member;wherein a fixed shaft to and from which the fold back portion is attached and detached is provided at the recess portion to be shifted from a linear line connecting the two through holes; andwherein when the attaching member is arranged at the first position, front end portions of the attaching shaft portions are projected to outside of the end-piece by widening the interval between the pinching portions by the fixed shaft pinched by the pinching portions of the fold back portion, and when the attaching member is arranged at the second position by detaching the fold back portion from the fixed shaft, the front end portions of the attaching shaft portions are immersed into the end-piece.

2. A wristwatch according to claim 1; wherein a front end side portion of the fixed shaft is made to be bolder than a root side portion of the fixed shaft pinched by the pinching portions.

3. A wristwatch according to claim 1; wherein a shape of the fold back portion in a free state is constituted by a U-like shape or a V-like shape.

4. A strap for a timepiece comprising: a strap for a timepiece provided at a wristwatch a case body of which is provided with a rod leg forming a rod crotch and having an attaching hole, and having an end-piece connected to the case body attachably thereto and detachably therefrom by being received by the rod crotch to be able to be brought thereto and therefrom;wherein a recess portion is formed at a back face of the end-piece;wherein through holes are respectively provided at side walls of the end-piece disposed on both sides of the recess portion;wherein an attaching member including a fold back portion having pinching portions opposed to each other and capable of being elastically deformed in a direction of widening and a direction of narrowing an interval between the pinching portions, and attaching shaft portions rotatably inserted into the through holes by being folded to bend from the two pinching portions in directions of being remote from each other is contained in the recess portion movably between a first position and a second position by rotating the attaching member;wherein a fixed shaft to and from which the fold back portion is attached and detached is provided at the recess portion to be shifted from a linear line connecting the two through holes; andwherein when the attaching member is arranged at the first position, front end portions of the attaching shaft portions are projected to outside of the end-piece by widening the interval between the pinching portions by the fixed shaft pinched by the pinching portions of the fold back portion, and when the attaching member is arranged at the second position by detaching the fold back portion from the fixed shaft, the front end portions of the attaching shaft portions are immersed into the end-piece.

5. A strap for a timepiece according to claim 4; wherein a front end side portion of the fixed shaft is made to be bolder than a root side portion of the fixed shaft pinched by the pinching portions.

6. A strap for a timepiece according to claim 4; wherein a shape of the fold back portion in a free state is constituted by a U-like shape or a V-like shape.
