Watch and strap

Abstract

A watch according to an embodiment, whose strap is replaceable, improves in maintainability and ensures that outward appearance is not of low quality. The watch according to an embodiment includes an exterior case having a pair of strap-attaching parts with insertion holes formed so as to face each other; an elastic pin formed of a built-in elastic body, having both ends inserted in the insertion holes of the pair of strap-attaching parts, and thereby being held by the strap-attaching parts; a connecting block disposed at one end of a strap and having a bottom surface with a groove formed therein, the connecting block connecting the strap to the exterior case by the pin held by the strap-attaching parts being housed in the groove; and a cover covering the groove housing the pin. An operating part to be operated to shorten both ends of the pin so that the pin is removable from the strap-attaching parts is formed on a side surface of the pin. The cover leaves a position corresponding to the operating part open so that the operating part is operable from outside with the pin housed in the groove.

1 . A watch comprising:
 an exterior case having a pair of strap-attaching parts with insertion holes formed so as to face each other;   a pin having both ends inserted in the insertion holes of the pair of strap-attaching parts and thereby being held by the strap-attaching parts;   a connecting block disposed at one end of a strap and having a bottom surface with a groove formed therein, the connecting block connecting the strap to the exterior case by the pin held by the strap-attaching parts being housed in the groove; and   a cover covering the groove housing the pin, wherein   the pin includes an elastic body pressing the ends to enable the ends to be translated in an axial direction,   an operating part to be operated to translate the ends toward the center of the pin is formed on a side surface of the pin so that the pin is removable from the strap-attaching parts, and   the cover leaves a position corresponding to the operating part open so that the operating part is operable from outside with the pin housed in the groove.   
     
     
         2 . The watch according to  claim 1 , wherein
 the cover covers the whole length of the groove, and   the cover has an opening formed at the position corresponding to the operating part.   
     
     
         3 . The watch according to  claim 2 , wherein
 the operating part projects from the opening to the outside of the cover.   
     
     
         4 . The watch according to  claim 3 , wherein
 the pin is housed in the groove so as to be circumferentially rotatable,   the opening has a notch formed in a rotating direction of the pin, and   the cover restrains the operating part from being operated to shorten the pin, with the operating part housed in the notch.   
     
     
         5 . The watch according to  claim 3 , wherein
 the pin is housed in the groove so as to be circumferentially rotatable,   the opening has a notch formed in a rotating direction of the pin, and   the cover restrains the pin that has been shortened from elongating, with the operating part housed in the notch.   
     
     
         6 . The watch according to  claim 2 , wherein
 the cover is formed separately from the connecting block and includes an extending part extending on a side surface of the connecting block,   the extending part has an insertion hole in which the pin housed in the groove is inserted, and   the cover is held on the connecting block, with the groove covered, by the pin being inserted in the insertion hole of the extending part.   
     
     
         7 . The watch according to  claim 1 , wherein
 the cover is joined to the connecting block and covers part of the length of the groove so as to restrain the pin housed in the groove from falling off the groove.   
     
     
         8 . A strap comprising:
 a pin having both ends inserted in insertion holes formed in a pair of strap-attaching parts included in an exterior case and thereby being held by the strap-attaching parts;   a connecting block disposed at one end of a strap and having a bottom surface with a groove formed therein, the connecting block connecting the strap to the exterior case by the pin held by the strap-attaching parts being housed in the groove; and   a cover covering the groove housing the pin, wherein   the pin includes an elastic body pressing the ends to enable the ends to be translated in an axial direction,   an operating part to be operated to translate the ends toward the center of the pin is formed on a side surface of the pin so that the pin is removable from the strap-attaching parts, and   the cover leaves a position corresponding to the operating part open so that the operating part is operable from outside with the pin housed in the groove.   
     
     
         9 . The watch according to  claim 4 , wherein
 the pin is housed in the groove so as to be circumferentially rotatable,   the opening has a notch formed in a rotating direction of the pin, and   the cover restrains the pin that has been shortened from elongating, with the operating part housed in the notch.   
     
     
         10 . The watch according to  claim 3 , wherein
 the cover is formed separately from the connecting block and includes an extending part extending on a side surface of the connecting block,   the extending part has an insertion hole in which the pin housed in the groove is inserted, and   the cover is held on the connecting block, with the groove covered, by the pin being inserted in the insertion hole of the extending part.   
     
     
         11 . The watch according to  claim 4 , wherein
 the cover is formed separately from the connecting block and includes an extending part extending on a side surface of the connecting block,   the extending part has an insertion hole in which the pin housed in the groove is inserted, and   the cover is held on the connecting block, with the groove covered, by the pin being inserted in the insertion hole of the extending part.   
     
     
         12 . The watch according to  claim 5 , wherein
 the cover is formed separately from the connecting block and includes an extending part extending on a side surface of the connecting block,   the extending part has an insertion hole in which the pin housed in the groove is inserted, and   the cover is held on the connecting block, with the groove covered, by the pin being inserted in the insertion hole of the extending part.   
     
     
         13 . The watch according to  claim 9 , wherein
 the cover is formed separately from the connecting block and includes an extending part extending on a side surface of the connecting block,   the extending part has an insertion hole in which the pin housed in the groove is inserted, and   the cover is held on the connecting block, with the groove covered, by the pin being inserted in the insertion hole of the extending part.
