Definitions

  • the present invention relates to a door handle, and more particularly to a door handle for providing a buffering effect.
  • a conventional door handle comprises a pair of handle levers and a pair of bases.
  • the two bases are oppositely installed on the two sides of a door plank, and the two handle levers are rotatably inserted into the two bases, respectively.
  • a latch tongue that is retractably mounted on the door plank connects to the two handle levers via a connector. When a user turns the handle levers, the latch tongue will be retracted, so the user can open the door.
  • each one of the pair of conventional door handles comprises a base 90, a handle lever 91, a linker 92, and an elastic component 93.
  • the linker 92 is connected to the handle lever 91, and is rotatable relative to the base 90 by the handle lever 91.
  • the linker 92 is connected to the latch tongue.
  • the elastic component 93 is disposed between and connected to the base 90 and the linker 92, so the elastic component 93 is able to offer a restoring torque to drive the linker 92 and the handle lever 91 to revolve backwardly after the user releases the handle lever 91.
  • the main objective of the present invention is to provide a door handle for providing a buffering effect which is able to retard the restoring swing-back process of a handle lever, in order to solve the problems of hurting the user and the loud noises produced during the process.
  • the door handle for providing a buffering effect comprises a base, a rotator, an elastic component, a linker, a handle lever, and a damper.
  • the base has an installation hole, two sockets, a limiting rod, and a shaft.
  • the installation hole is disposed through the base and is connected to an outer side and an inner side of the base.
  • the two sockets are disposed on the inner side of the base and on two sides of the installation hole.
  • the limiting rod protrudes on the inner side of the base and is located below the two sockets.
  • the shaft protrudes on the inner side of the base and is located beside one of the two sockets.
  • the rotator is rotatably engaged with the installation hole of the base and has a noncircular handle hole disposed through the center of the rotator.
  • the elastic component has its two ends respectively hooking the limiting rod of the base and the rotator.
  • the linker is disposed around the rotator and has a restricting rib and a pivot rod.
  • the restricting rib extends from the linker into an area between the limiting rod and the socket that is other than the socket beside the shaft.
  • the pivot rod protrudes on the linker and is spaced apart from the restricting rib.
  • the handle lever has a noncircular end for insertion into the handle hole of the rotator.
  • the damper has a mini buffer, a pivot arm, and an extending arm.
  • the mini buffer comprises a cylinder body mounted to the base, and a piston rod that retractably extends from the cylinder body.
  • the pivot arm is disposed around the shaft by a middle portion and has one of two ends rotatably mounted to the piston rod of the mini buffer.
  • the extending arm has two ends rotatably mounted to the other one of the two ends of the pivot arm and the pivot rod of the linker, respectively.
  • a door handle for providing a buffering effect in accordance with the present invention comprises a base 10, a rotator 20, an elastic component 30, a linker 40, a handle lever 50, a damper 60, and a cover 70.
  • the base 10 is a rectangular cap, and has an inner side, an outer side, an installation hole 11, two sockets 12, a limiting rod 13, a shaft 14, and a fixing rod 15.
  • the installation hole 11 is formed through the base 10 to communicate with the inner side and the outer side of the base 10.
  • the two sockets 12 are disposed on the inner side of the base 10, and are disposed on two opposite sides along a radial direction of the installation hole 11.
  • the two sockets 12 are tubular in shape.
  • the limiting rod 13 is disposed below the two sockets 12.
  • the shaft 14 protrudes beside one of the two sockets 12, away from the installation hole 11.
  • the fixing rod 15 protrudes adjacent to the limiting rod 13.
  • the rotator 20 is rotatably mounted to the installation hole 11 of the base 10, and has a rotation center, an inner end, a surface, a handle hole 21 and a slot 22.
  • the handle hole 21 is formed through the rotation center of the rotator 20, and has a noncircular shape. In the present embodiment, the handle hole 21 is rectangular.
  • the slot 22 is recessed from the inner end of the rotator 20, and the slot 22 communicates with the handle hole 21.
  • the rotator 20 has a C-clip 23 engaged with the surface of the rotator 20 near the inner end of the rotator 20.
  • the elastic component 30 is connected to the base 10 and the rotator 20, with one of two ends of the elastic component 30 hooking the limiting rod 13, and the other one of the two ends hooking the slot 22.
  • the elastic component 30 is a torsion spring.
  • the linker 40 is engaged with the rotator 20, and makes the elastic component 30 located between the base 10 and the linker 40.
  • the linker 40 comprises an inner circumference, an outer circumference, two connecting ribs 41, a restricting rib 42, a pivot rib 43, and a pivot rod 44.
  • the two connecting ribs 41 respectively protrude inwardly from two diametrically opposite points on the inner circumference of the linker 40, and the two connecting ribs 41 are engaged into two ends of the slot 22.
  • the restricting rib 42 is disposed on the outer circumference of the linker 40, and the restricting rib 42 extends into an area between the limiting rod 13 and one of the two sockets 12.
  • the pivot rib 43 is disposed on an opposite side of the linker 40, relative to the restricting rib 42.
  • the pivot rod 44 is protruded on the pivot rib 43 away from the base 10.
  • the C-clip 23, which is engaged with the rotator 20, enables the linker 40 and the elastic component 30 to firmly mount to the rotator 20, and prevents the linker 40 from falling off the rotator 20.
  • the handle lever 50 is L-shaped and has a noncircular cross section.
  • the cross section is rectangular, which corresponds to the handle hole 21.
  • the handle lever 50 comprises two ends. One of the two ends of the handle lever 50 is inserted into the handle hole 21 of the rotator 20, and a user can grab on the other one of the two ends of the handle lever 50 so as to turn the handle lever 50.
  • the damper 60 is movably mounted to the base 10 and is connected to the linker 40.
  • the damper 60 comprises a mini buffer 61, a pivot arm 62, and an extending arm 63.
  • the mini buffer 61 comprises a cylinder body 610 and a piston rod 611.
  • the cylinder body 610 is disposed around the fixing rod 15 of the base 10, and the piston rod 611 retractably extends from the cylinder body 610.
  • the mini buffer 61 can be either a hydraulic cylinder or a pneumatic cylinder.
  • the pivot arm 62 has a shaft hole 620 formed through a middle portion of the pivot arm 62, and the pivot arm 62 is rotatably mounted to the shaft 14 via the shaft hole 620.
  • the extending arm 63 is connected with the pivot arm 62 and the pivot rod 44, by two ends of the extending arm 63 rotatably mounted to the pivot rod 44 and the other end of the pivot arm 62, which is away from the mini buffer 61, respectively.
  • the cover 70 covers the inner side of the base 10, to make the rotator 20, the elastic component 30, the linker 40, and the damper 60 received and mounted inside the base 10.
  • the cover 70 has a through hole 71 and two assembly holes 72.
  • the through hole 71 is formed through the cover 70 and aligns with the installation hole 11.
  • the two assembly holes 72 are formed through the cover 70, and are respectively aligned with the two sockets 12.
  • the first step is to prepare a pair of the door handles mentioned above.
  • install the two door handles on a door plank 80 and fasten the two bases 10 with pins (not shown in the figures) through the sockets 12 and the door plank 80.
  • a front side of the door plank 80 engages a latch tongue 81.
  • the latch tongue 81 is connected to the two rotators 20 of both of the door handles.
  • a restoring torque provided by the elastic component 30 drives the rotator 20 to rotate backwardly.
  • the linker 40 is therefore pulled, making the restricting rib 42 revolve backwardly and contact on the limiting rod 13.
  • the pivot rod 44 pulls the extending arm 63 to move leftward (with reference to Fig. 3 ). Consequently, the pivot arm 62 revolves in a counterclockwise direction, and pulls the piston rod 611 out of the cylinder body 610, to an extended position.
