A door inside handle apparatus with a pull handle according to embodiments of the present invention is described hereafter in detail with reference to the accompanying drawings.
A door inside handle apparatus with a pull handle according to the present invention, as shown in FIGS. 3 to 7, includes: a handle bracket 20 fixed to a pull handle 10 without interfering with a storage space 11 of the pull handle 10; a door inside handle 30 coupled to the handle bracket 20 to be turned and having an operation part, which is operated by a user, exposed through the rear side of the pull handle 10; a link lever 40 coupled to the handle bracket 20 to be turned, connected with one end of a latch cable 7, and operated to pull the latch cable 7 by rotating with the door inside handle 30; and a return spring 50 having one end coupled to a handle shaft 31, which is the turning center of the door inside handle 30, the other end connected to the handle bracket 20, and providing a return force when the door inside handle 30 is turned.
The pull handle 10 is fixed to the armrest of a door in general structures, but is not limited thereto.
In the door inside handle 30 of which one end is coupled to the handle shaft 31 and the other end functions as the operation part, an operation protrusion 32 and an operation groove 33 are vertically disposed to be connected on the operation part, or the operation part includes an operation protrusion 32 and an operation groove 33 formed substantially vertically adjacent to each other. The operation protrusion 32 is exposed to the outside through a through-hole 12 formed in the rear side of the pull handle 10.
That is, according to the present invention, only the operation protrusion 32 of the door inside handle 30 which a user touches with a hand is exposed to the outside through the through-hole 12 of the pull handle 10, so that the exposed portion is minimized and the external appearance can be improved. The operation protrusion 32 of the door inside handle 30 prevents the user's hand from sliding and the operation groove 33 has an arc cross-section, so it allows a user to more conveniently grip the handle.
The present invention further includes a damper 60 fitted in the through-hole 12 of the pull handle 10, and absorbing shock and preventing noise when it comes in contact with the operation protrusion 32 due to the operation of the door inside handle 30. The damper 60 may be made of rubber, silicon, plastic resin etc., but is not limited thereto.
A locking step 34 for contact with the link lever 40 is integrally or monolithically formed on the door inside handle 30 and it may be formed at a position between the handle shaft 31 and the operation groove 33.
The link lever 40 has a pivot center 42 coupled to the handle bracket 20 to pivot by a lever shaft 41, a cable connection portion 43 extending to a side from the pivot center 42 and connected with one end of the latch cable 7, and a handle contact portion 44 extending to the other side from the pivot center 42 and contacting with the locking step 34 of the door inside handle 30.
For easy contact of the handle contact portion 44 of the link lever 40 with the locking step 34 of the door inside handle 30, the lever shaft 41 may be disposed behind further than the handle shaft 31, and to this end, a specific lever mounting bracket 45 may be used. That is, the lever mounting bracket 45 may be coupled to the handle bracket 10 and the pivot center 42 of the link lever 40 may be coupled to the lever mounting bracket 45 to pivot by the lever shaft 41.
As described above, since the door inside handle 30 that operates a door latch in a vehicle is integrated with the pull handle 10 in various embodiments of the present invention, there is no need of providing a specific space for the door inside handle 30 on a door trim. Therefore, it is possible to reduce the work processes and particularly more freely design a door trim, so that it contributes for elegant image of a vehicle.
Further, since only the operation protrusion 32 of the door inside handle 30 which a user operates with a hand is exposed to the outside through the through-hole 12 of the pull handle 10, it is possible to conveniently operate the door inside handle 30, and particularly, the exposed portion can be minimized so that the external appearance can be improved.
Further, since the door inside handle apparatus according to the present invention does not interfere with the storage space 11 of the pull handle 10, it is possible to usefully use the storage space 11 of the pull handle 10.
