Hinge assembly having a torque device to provide an assistance to assist a pivotal movement of a display relative to a base of a laptop computer

Abstract

A hinge includes a sleeve and a shank. The shank is composed of an elongated body, a connecting portion and a securing portion. The connecting portion has a diameter smaller than that of the elongated body and larger than a diameter of the securing portion. The sleeve has an inner diameter smaller than that of the connecting portion such that after the connecting portion is received inside the sleeve, an interference fit is existed between the sleeve and the connecting portion of the shank.

1 . In a hinge having a shank provided with an elongated body, a connecting portion extending from a free end of the elongated body and a securing portion extending from a free end of the connecting portion and having a diameter smaller than that of the connecting portion, a first bracket having a plate adapted to securely engage with a base of a laptop computer and securely mounted on the connecting portion, a securing plate securely mounted on the securing portion, a resilient member securely mounted on the securing portion, a securing member securely mounted on the securing portion to secure engagement of the resilient member, the securing plate and the first bracket on the securing portion and a second bracket securely connected to the shank to adapt to securely engage with a display of the laptop computer, the second bracket being pivotal relative to the first bracket, wherein 
 a sleeve is formed on a free end of the plate to receive therein the connecting portion and a gap is defined between the sleeve and the plate,    the connecting portion has a diameter smaller than that of the elongated body and the securing portion has a diameter smaller than that of the connecting portion such that after the connecting portion is received in sleeve, an interference fit is existed between the connecting portion and the sleeve.    
     
     
         2 . The hinge assembly as claimed in  claim 1 , wherein the sleeve has an inner diameter smaller than that of the connecting portion so that the connecting portion is interference-fitted inside the sleeve.  
     
     
         3 . In a hinge having a shank provided with an elongated body, a connecting portion extending from a free end of the elongated body and a securing portion extending from a free end of the connecting portion and having a diameter smaller than that of the connecting portion, a first bracket having a plate adapted to securely engage with a base of a laptop computer and securely mounted on the connecting portion, a securing plate securely mounted on the securing portion, a resilient member securely mounted on the securing portion, a securing member securely mounted on the securing portion to secure engagement of the resilient member, the securing plate and the first bracket on the securing portion and a second bracket securely connected to the shank to adapt to securely engage with a display of the laptop computer, the second bracket being pivotal relative to the first bracket, wherein 
 a sleeve is formed on a free end of the plate to receive therein the connecting portion and a gap is defined between the sleeve and the plate,    the connecting portion has a diameter smaller than that of the elongated body and the securing portion has a diameter smaller than that of the connecting portion such that after the connecting portion is received in sleeve, an interference fit is existed between the connecting portion and the sleeve, wherein the sleeve has an inner diameter smaller than that of the connecting portion so that the connecting portion is interference-fitted inside the sleeve.
