As such, the spring 500 is not permitted into a flexure state during a compression thereof.

  • the engaging protrusion 410 stays inserted in the stopping groove 211 and an expansion force of the springs 500 acts. Thus, rotation is not permitted. Further, the stopping grooves 211 are covered up by the cover portion 110 and are thus not exposed outwardly.
  • the engaging protrusion 410 formed at the stopper 400 is gradually separated apart from the stopping groove 211. Further, the stopper 400 is moved toward the springs 500 while compressing the springs 500. In such a case, the springs 500 are vertically compressed due to the guide projections 420 without any leftward or rightward flexure.
  • the stopper 400 is moved to the next stopping groove 211 and is seated therein by means of the expansion force of the springs 500, as shown in Fig. 8.
  • the supporting member 100 In the rotation of the supporting member 100, the supporting member 100 is rotated in such a manner that its upper end is increasingly separated away from the electronic device 700. As a back face of the supporting member 100 is placed into contact with the surface, the supporting member 100 supports the electronic device 700. Contacting the back face of the supporting member 100 to the surface enlarges the contact area therebetween, thereby providing a stable stance of the electronic device 700.
  • the engaging protrusion 410 provided at the stopper would not be properly seated in the stopping groove 211. This is because the expansion force of the springs 500 is weakened due to such curvature or bent. As such, the supporting member 100 fails to stop at a desired angle and is thus apt to rotate easily.
  • the support device does not allow the springs 500 to buckle through the guide projections 420 provided at the stopper 400, thereby increasing the force efficiency of the springs 500. Consequently, the engagement force between the engaging protrusion 410 provided at the stopper 400 and the stopping groove 211 is enhanced.
  • the support device for an electronic device of the present invention should not be limited to the above-described embodiments and may be embodied in various manners within the scope of the subject matter of the present invention.

Abstract

La présente invention porte sur un dispositif de support pour dispositifs électroniques, qui améliore l'efficacité d'une force agissant pour supporter le dispositif électronique afin d'améliorer une force d'accouplement, et qui minimise une exposition extérieure de ses composants. Le dispositif de support est monté de façon rotative sur un dispositif électronique pour supporter ce dernier à un angle prédéterminé. Le dispositif de support comprend : une butée montée de façon coulissante sur l'un du dispositif de support et du dispositif électronique ; un ressort pour exercer une force élastique sur la butée ; et une rainure d'arrêt formée au niveau de l'autre du dispositif de support et du dispositif électronique, la butée pouvant être insérée dans la rainure d'arrêt. La butée est configurée pour entourer le ressort de façon à empêcher le ressort de subir un flambage durant une compression du ressort. Etant donné que la butée limite le ressort de façon à ne pas flamber le ressort, une efficacité d'action du ressort augmente.
