Abstract

A door handle assembly includes a handle body 1, a pivot seat (fig 2, 2), and a tetragonal rod 3. The handle body has a pivot portion (fig 5, 11) having a width larger than or equal to the top portion 31 of the tetragonal rod 3, and able to receive said top portion 31. The top portion 31 of the tetragonal rod 3 has a plurality of cutaway corners to form cut surfaces 311 and engaging notches 312 which are disposed under the cut surfaces 311. The pivot seat has a main pivot hole and is provided with a rotation disk 22 and a rotation board 23. The rotation disk 22 has a resilient flange (fig 1-B, 222) protruding around a through hole 221. When assembled, the engaging notches 312 of the tetragonal rod 3 engage with the resilient flange 222 to position the rotation disk 22 in place. The pivot portion of the handle body 1 is fitted on the top portion 31 of the tetragonal rod 3. The arrangement allows for simple and quick handle assembly/disassembly.

DOOR HANDLE ASSEMBLY

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a door handle assembly, and more particularly to a door handle assembly having a protruding resilient flange to engage with engaging notches disposed on a top portion of a tetragonal rod for replacement.

2. Description of the PriorArt

A conventional door handle assembly, as shown in Fig. 6 and Fig. 6-A, comprises a pivot portion 41 which is disposed at a lower section of a handle body 4. The pivot portion 41 is fitted on a top portion 6lof a tetragonal rod 6. The bottom of the handle body 4 is engaged with a slide board 42. A pivot seat 5 is provided under the slide board 42. The pivot seat 5 has a main pivot hole 51 and a disk trough 511 under the main pivot hole 51. The disk trough 511 is to receive a rotation disk 52 which has a central through hole 521 and a stop trough 522. A rotation board 53 having a rectangular hole 531 is placed in the stop trough 522. The tetragonal rod 6 is inserted through the rectangular hole 531 to drive rotation. The top portion 61 has cutaway corners to form a plurality of cut surfaces 611, and passes through the through hole 521 for free rotation, as shown in Fig. 7. The pivot portion 41 has a width smaller than that of the top portion 61. After pressed, the pivot portion 41 is tightly fixed to the top portion 61 of the tetragonal rod 6, as shown in Fig. 8. The conventional door handle assembly cannot be replaced with a new tetragonal rod 6 that is in different length.

This increases maintenance and material cost.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a door handle assembly which comprises a handle body, a pivot seat and a tetragonal rod. The handle body has a pivot portion which is disposed at a lower section thereof to receive a top portion of the tetragonal rod. The handle body has a bottom to engage with a slide board.

The pivot portion of the handle body has a width larger than or equal to that of the top portion of the tetragonal rod. The pivot seat has a main pivot hole and a disk trough which is disposed under the main pivot hole. The disk trough is adapted to receive a rotation disk. The rotation disk has a through hole and a stop trough which is used to receive a rotation board. The rotation board has a central rectangular hole. The rotation disk further has a resilient flange protruding around the through hole. The rotation board is located between the disk trough and the stop trough. The tetragonal rod inserts through the rectangular hole of the rotation board of the pivot seat. The top portion of the tetragonal rod has a plurality of cutaway corners to form cut surfaces for the top portion of the tetragonal rod to be inserted through the through hole of the rotation disk of the pivot seat. The top portion of the tetragonal rod further has engaging notches which are disposed under the cut surfaces. The engaging notches are used to position and engage with the resilient flange of the rotation disk. Thus, the tetragonal rod is inserted through the through hole, the rectangular hole and the main is pivot hole. The engaging notches under the cut surfaces engage with the resilient flange to position the rotation disk in place. The pivot portion of the handle body is fitted on the top portion of the tetragonal rod.

Preferably, the rotation disk further has at least one notch close to the resilient flange to facilitate assembly and disassembly of the tetragonal rod with respect to the rotation disk.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

Referring to Fig. 1, Fig. 2, Fig. 5, Fig. 1-A, Fig. 1-B, the present invention comprises a handle body 1, a pivot seat 2, and a tetragonal rod 3. The handle body I has a pivot portion 11 which is disposed at a lower section thereof to receive a top portion of the tetragonal rod 3. The handle body I has a bottom to engage with a slide board 12.

The pivot portion 11 has a width larger than or equal to that of a top portion 31 of the tetragonal rod 3, so that the top portion 31 which can be in different length is attached to the pivot portion 11. The pivot seat 2 has a main pivot hole 21 and a disk trough 22 which is disposed under the main pivot hole 21. The disk trough 22 is adapted to receive a rotation disk 22. The rotation disk 22 has a through hole 221 and a stop trough 223 which is used to receive a rotation board 23. The rotation board 23 has a central rectangular hole 231. The rotation disk 22 further has a resilient flange 222 protruding from the through hole 221. The rotation board 23 is located between the disk trough 211 and the stop trough 223. The tetragonal rod 3 corresponds in shape to the rectangular hole 231 of the rotation board 23 of the pivot seat 2. The top portion 31 has a plurality of cutaway corners to form cut surfaces 311 for the top portion 31 to be inserted through the through hole 221 of the rotation disk 22 of the pivot seat 2. The top portion 31 of the tetragonal rod 3 further has engaging notches 312 which are disposed under the cut surfaces 311. The engaging notches 312 are used to position and engage with the resilient flange 222 of the rotation disk 22. By this configuration, the present invention can be assembled and disassembled without the need of the press unit.

Referring to Fig. 1, Fig. 3, Fig. 4, Fig. 4-A, the rotation board 23 is disposed in the stop trough 223 of the rotation disk 22 and placed in the disk trough 211, so that the rotation board 23 is located between the disk trough 211 and the stop trough 223. The tetragonal rod 3 is inserted through the through hole 221, the rectangular hole 231 and the main pivot hole 21. The engaging notches 312 under the cut surfaces 311 engage with the resilient flange 222 to position the rotation disk 22 in place. After that, the pivot portion 11 of the handle body 1 is fitted on the top portion 31. When the user wants to replace the handle body 1, the pivot portion 11 of the handle body 1 is disengaged from the top portion 31 and then the pivot portion 11 of another handle body 1 is fitted on the top portion 31. When the user wants to replace the tetragonal rod 3, the pivot portion 11 of the handle body 1 is disengaged from the top portion 31 through the engaging notches 312 and the deformation of the resilient flange 222 so as to pull out the tetragonal rod 3. The original parts can be assembled according to the aforesaid. The present invention can assembled and disassembled simply and quickly.

The rotation disk 22 further has at least one notch 2221 close to the resilient flange 222 to facilitate the assembly and disassembly of the tetragonal rod 3 with respect to the rotation disk 22.

Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
