Wearable electronic device

Abstract

A wearable electronic device is provided which can prevent the main body of the device from making swinging movement relative to its rigid band portion. The wearable electronic device is provided with: an electronic device main body; a rigid band allowing the electronic device main body to be worn on a neck-like portion; a pivotal coupling mechanism for coupling the rigid band to a casing of the electronic device main body for pivoting movement in two directions between a closed position for surrounding the neck-like portion and an open position for allowing detachment thereof from the neck-like portion, in cooperation with the casing of the electronic device main body. The pivotal coupling mechanism includes an elastic biasing member biasing the rigid band from the closed position toward the open position, and a locking mechanism for open position which locks the rigid band in the open position when the rigid band is in the open position.

What is claimed is:  
     
         1 . A wearable electronic device comprising: 
 an electronic device main body;    a rigid band for allowing mounting of the electronic device; and    a coupling mechanism for coupling the rigid band to the electronic device main body,    wherein the coupling mechanism has: 
 an elastic body for elastically biasing the rigid band in an opening direction thereof; and  
 a locking mechanism for locking the rigid band onto the electronic device main body when the rigid band is in its open or closed position, in order to suppress swinging movement of the rigid band relative to the electronic device main body.  
   
     
     
         2 . A wearable electronic device according to  claim 1 , 
 wherein the locking mechanism comprises: 
 an engaging pin provided to one of the electronic device main body and the rigid band so as to be capable of elastically projecting therefrom; and  
 an engaging concave portion which is formed in the other one of the electronic device main body and the rigid band such that the engaging pin is fitted and locked therein when the rigid band is in its open or closed position.  
   
     
     
         3 . A wearable electronic device according to  claim 2 , wherein: 
 the engaging pin has a rounded configuration at its tip portion; and    the engaging concave portion is formed of an elastic material in its peripheral wall portion.    
     
     
         4 . A wearable electronic device according to  claim 1 , wherein the coupling mechanism includes: 
 a locking mechanism for closed position, which locks the rigid band onto the electronic device main body when the rigid band is in its closed position; and    a locking release mechanism for closed position, which releases the locking of the rigid band effected by the locking mechanism for closed position.    
     
     
         5 . A wearable electronic device according to  claim 4 , wherein the locking mechanism for closed position comprises: 
 an engaging pin provided to the rigid band so as to be capable of elastically projecting therefrom; and    an engaging concave portion formed in the electronic device main body such that the tip portion of the engaging pin is fitted and locked therein when the rigid band is in its closed position.    
     
     
         6 . A wearable electronic device according to  claim 5 , 
 wherein the locking release mechanism for closed position comprises a pushing mechanism for pushing from the outside the engaging pin that is fitted and locked in the engaging concave portion.    
     
     
         7 . A wearable electronic device according to  claim 2 , 
 wherein the locking mechanism includes an adjustment mechanism for adjusting the closed position of the rigid band by adjusting a locking angle of the engaging pin relative to the engaging concave portion.    
     
     
         8 . A wearable electronic device according to  claim 7 , wherein the adjustment mechanism comprises: 
 a cylindrical member provided with the engaging pin; and    an adjusting screw engaging with the cylindrical member and capable of causing the cylindrical member to rotate.    
     
     
         9 . A wearable electronic device according to  claim 7 , wherein the adjustment mechanism comprises: 
 a cylindrical member provided with the engaging pin and having a cylinder portion, the cylinder portion having in a side surface thereof a long hole that penetrates from an outer peripheral portion to an inner peripheral portion thereof;    a sliding member which has a convex portion to be engaged with the long hole and is inserted into the cylinder portion of the cylindrical member; and    an adjusting screw engaging with the sliding member and capable of causing the sliding member to rotate, and    wherein the sliding member is rotated by means of the adjusting screw to allow sliding movement of the convex portion within the long hole, to thereby adjust a locking angle of the engaging pin relative to the engaging concave portion.    
     
     
         10 . A wearable electronic device according to  claim 7 , 
 wherein the adjustment mechanism comprises: 
 a cylindrical member provided with the engaging pin and having a long hole formed on an end surface thereof;  
 a sliding member which has a convex portion to be engaged with the long hole and is capable of sliding movement in a radial direction of the cylindrical member; and  
 an adjusting screw engaging with the sliding member and capable of causing the sliding member to make linear movement, and  
   wherein the sliding member is linearly moved by means of the adjusting screw to allow sliding movement of the convex portion within the long hole, to thereby adjust a locking angle of the engaging pin relative to the engaging concave portion.
