Abstract

DC60 This invention presents a door handle device that provides appropriate braking for return to the pre-control position of the door opening lever, without hindering, for example, the pulling of the door opening lever, even in the event of ice buildup inside the door. A braking device 7 provides resistance to the compressive movement of piston 71, compression section 2c of the door opening lever 71. A cam surface 2d is constructed to increase the distance between the lever and the moving shaft 2a. As it approaches the cam end 2e of the braking device 7, the connecting rod 72 is fixed to the deepest end of the storage section 9, and a gap 9c is created between the outer surface of cylinder 70 and the inner surface of storage section 9. The deepest end 70a of cylinder 70 is made to constantly engage the cam surface 2d of the door opening lever 2. By the aforementioned force, the cam end 2c of the aforementioned cam surface 2d is made... The piston 71 is forced into the deepest end of cylinder 70a while the door opening lever 2 is not controlled, maximizing the force of piston 71 into cylinder 70. Figure 3 is used as the chosen illustration. This invention presents a door handle device that provides appropriate braking for recoil to a position prior to the control of the door opening lever, without hindering, for example, the operation of the door opening lever, even in the event of ice buildup inside the door. A braking device 7 provides resistance to the inward movement of piston 71. The compression 2c of the door opening lever 71 has a cam surface 2d which is designed to increase the distance between the camshaft 2a and the moving shaft. As it approaches the end of cam 2e, the braking device 7 is further inward. The piston rod 72 is fixed to the deepest end of storage section 9, and a gap 9c is created between the surfaces. The outer surface of cylinder 70 and the inner surface of storage section 9, and the deepest point 70a of cylinder 70 are made to constantly contact the cam surface 2d of gate lever 2. By the aforementioned force, the end of cam 2c of the aforementioned cam surface 2d is made to contact the deepest point 70a of cylinder 70 while gate lever 2 is not controlled, so that piston 71 is compressed as much as possible into cylinder 70. (Figure 3 is used for this calculation.)

Claims (4)

Revised 27/12/2016 1. The door opening mechanism consists of a door opening lever, which is mounted to the door panel side allowing it to rotate and is connected to the door latch device to hold the door open with a controlled pull. A braking device has a forced path that forces the cylinder, piston, connecting rod, and plunger to rotate in a direction that keeps them apart from the deepest point of the cylinder at all times, creating fluid resistance contained within the cylinder against the recoiling motion of the piston. A storage section of this braking device, fixed to the door panel where the opening lever is located, designates one side, which holds the rotating shaft, as the control side, and the other side as the compression side. The compression side has a cam surface designed to increase the distance between the cam and the rotating shaft as it approaches the end of the cam. The control device's connecting rod is fixed to the deepest point of the storage section, and a gap is created between the outer surface of the cylinder and the inner surface of the storage section. The end of the cylinder is designed to constantly contact the cam surface of the door opening lever. 1. Under the aforementioned force, the distal end of the cam surface is forced to strike the deepest end of the cylinder while the door lever is not controlled, so that the piston is pushed into the cylinder as much as possible. 2. The door handle device specified in claim 1 is characterized by the end of the cylinder being constructed of at least a low-friction synthetic resin. 1. The door handle mechanism is characterized by a lever that is mounted to the door panel, allowing it to rotate. This lever is connected to a door latch mechanism, enabling the door to be opened by a pull. A braking system works by forcing the cylinder, piston, connecting rod, and piston pin to constantly move away from the deepest point of the cylinder. This creates fluid resistance within the cylinder against the recoiling motion of the piston, which opposes this braking force. A storage section of this braking system is attached to the door panel. The opening lever has one end clamping the rotating shaft as the control function and the other as the compression function. The compression section has a cam surface designed to increase the distance between the lever and the rotating shaft as it approaches the cam end. The control function involves a connecting rod attached to the deepest point of the storage section, with a gap created between the outer surface of the cylinder and the inner surface of the storage section. The end of the cylinder is designed to constantly contact the cam surface of the opening lever. With the force described above, the outermost end of the camshaft surface is forced to strike the deepest point of the cylinder while the door opening lever is not controlled, so that the piston is pushed as far back into the cylinder as possible. 2. The door handle device specified in Claim 1, which is characterized by the end of the cylinder being fitted with a synthetic resin with at least a low coefficient of friction. 3. The door handle device is characterized by a lever that is attached to the door panel, allowing it to rotate. This lever is connected to the door latch mechanism, which holds the door open by a pull control. A braking system works by forcing the cylinder, piston, connecting rod, and plunger to constantly move away from the deepest point of the cylinder, creating fluid resistance within the cylinder against the inward movement of the piston. A support for this braking system is attached to the door panel. The door handle lever has one side clamping the rotating shaft as the control function and the other side as the compression function. The compression function has a cam surface designed to increase the distance between the lever and the rotating shaft. As the cam surface approaches the deepest point of the shaft, the control function causes the cylinder to be held in place by the support, and the outer end of the connecting rod is forced to constantly contact the cam surface of the door handle lever. Under these control mechanisms, the deepest point of the cam surface is forced to contact the end of the connecting rod when the door handle lever is not engaged. To ensure the piston is pressed as far back into the cylinder as possible. 4. The door handle device is characterized by a door opening lever mounted on the door panel, allowing it to rotate. This lever is connected to the door latch mechanism, enabling the door to be opened by a pull. A linear motion brace supports the door panel, allowing it to move forward and backward. The braking mechanism of this linear motion brace, consisting of a housing and a small pinion, is supported by the housing and allows it to rotate. Fluid resistance, sealed within the housing, interferes with the rotation of the pinion. The brake is attached to one side of the linear motion brace and the door panel, and a rack is attached to the other side, coupling the pinion (braking mechanism). The door opening lever has one side clamping the rotating shaft as the control function and the other side as the compression function. The compression function has a cam face designed to increase the distance between the lever and the rotating shaft. As the cam face approaches the end of the linear motion, the end of the linear motion is positioned so that it constantly contacts the cam face of the door opening lever, acting as the aforementioned braking mechanism. The far end of the cam surface mentioned above is made to collide with the front end of the linear mover while the door opening lever is not controlled, so that the linear mover is retracted as far as possible.
