Door Handle Device

A door handle system comprising:

• a door opening lever swingably assembled to a door panel and configured to be linked to a door latch so as to open a door by pulling operation;
• a damper including a cylinder, a piston, a piston rod and a biasing member for constantly biasing the piston in a direction away from a depth end of the cylinder, the damper being configured so as to provide a resistance of a fluid to a retracting movement of the piston against the biasing action, the fluid being sealed in the cylinder;
• and
• a support for the damper, fixed to the door panel;
• wherein the door opening lever has an operating part formed on one end thereof and a pressing part formed on the other end thereof with respect to a swingable shaft, the pressing part having a cam surface, the cam surface being configured so as to have a distance from the swingable shaft gradually increasing toward a cam end;
• wherein the damper is configured so that the cylinder is fixed to the support, and that the piston rod has an outer end constantly brought into press-contact with the cam surface of the door opening lever under the biasing action;
• and
• wherein the damper is configured so that a portion of the cam surface close to the cam end is brought into press-contact with the outer end of the cylinder to retract the piston into the cylinder at a maximum when the door opening lever is not subjected to pulling operation.

A door handle system comprising:

• a door opening lever swingably assembled to a door panel and configured to be linked to a door latch so as to open a door by pulling operation;
• a linearly moving member supported by the door panel, the linearly moving member being configured so as to move back and forth;
• a biasing member for the linearly moving member;
• and
• a damper including a main body and a pinion rotatably supported by the main body, the damper being configured so as to provide a resistance of a fluid to a rotation of the pinion, the fluid being sealed in the main body;
• wherein one of the linearly moving member and the door panel has the damper fixed thereto, and the other is formed with a rack engageable with the pinion forming the damper;
• wherein the door opening lever has an operating part formed on one end thereof and a pressing part formed on the other end thereof with respect to a swingable shaft, the pressing part having a cam surface, the cam surface being configured so as to have a distance from the swingable shaft gradually increasing toward a cam end;
• wherein the linearly moving member has a front end constantly brought into press-contact with the cam surface of the door opening lever under a biasing action of the biasing member;
• and
• wherein the door opening lever is configured so that a portion of the cam surface close to the cam end is brought into press-contact with the front end of the linearly moving member to retract the linearly moving member at a maximum when the door opening lever is not subjected to pulling operation.
