## Title
Portable computer with handle attached thereto

## Abstract

A portable computer includes a main body, a retention portion being arranged on the main body with a part thereof spaced apart from the main body, and a fastener for detachably attaching a handle between the main body and the retention portion. A through hole is defined in the retention portion, a through hole is defined in the handle, and a locking aperture is defined in the main body. The fastener includes a hook extending through the through hole of the retention portion, the through hole of the handle, and the locking aperture of the main body.

## Background
FIELD OF THE INVENTION
The present invention relates to a portable computer, and more particularly to a portable computer incorporates a handle.
DESCRIPTION OF RELATED ART
Portable computers, such as laptop computers and notebook computers, have become increasingly popular for general use. To facilitate carrying portable computers, a handle is attached to a portable computer with screws. However, screwing or unscrewing the handle to the portable computer via screwdrivers is unduly cumbersome and time consuming. In addition, it is inconvenient for the users to assemble or disassemble the handle to or from the portable computer at anytime or anywhere needed.
What is desired, therefore, is a portable computer which has an improved fixing mechanism to attach the handle thereto.
SUMMARY OF INVENTION
In one preferred embodiment, a portable computer includes a main body, a retention portion being arranged on the main body with a part thereof spaced apart from the main body, and a fastener for detachably attaching a handle between the main body and the retention portion. A through hole is defined in the retention portion, a through hole is defined in the handle, and a locking aperture is defined in the main body. The fastener includes a hook extending through the through hole of the retention portion, the through hole of the handle, and the locking aperture of the main body. The locking aperture of the main body is not round, so that the fastener is rotatable to a position in which the hook engages with the main body beside an edge of the locking aperture.
Other advantages and novel features will become more apparent from the following detailed description of preferred embodiments when taken in conjunction with the accompanying drawings, in which:

DETAILED DESCRIPTION
Referring to FIGS. 1, 2 and 8, a handle 10 is provided to be used with a computer like a portable computer 20. The handle 10 is a functional part of the portable computer 20 and capable of being used as a carrying handle in one of its positions and a stand of the computer 20 in another of its positions. The handle 10 includes a crossbar 11, and a pair of arms 12 protruding from opposite ends of the crossbar 11 respectively. A through hole 121 is defined in a free end of each arm 12. The portable computer 20 includes a main body 21. For better illustration, an upper panel and a pivotable LCD panel 26 are omitted. A pair of retention portions 23 protrudes rearward along lateral sides of the main body 21 respectively. The retention portions 23 are spaced from the main body 21. A through hole 231 is defined in a free end of each retention portion 23. Two locking apertures 24 are defined in the main body 21 corresponding to each through hole 231. The two locking apertures 24 are symmetrical with each other. Each locking aperture 24 includes a wide access section 241, and a narrow locking section 242. A slim locking slot 25 is defined in the main body 21 in the vicinity of each locking section 242.
A pair fasteners 30 and a pair of resilient elements are provided to attach the handle 10 to the main body 21 of the portable computer 20. Referring also to FIG. 3, each fastener 30 includes a circular head portion 31, a hollow shaft 32 extending from the head portion 31, and a pair of clasp portions 33 extending from the shaft 32. An L-shaped hook 331 extends outwardly from a free end of each clasp portion 33. A slot 311 is defined in an outer surface of the head portion 31 of each fastener 30. The slot 311 is straight and has a relative wide width to facilitate users' operation. Each resilient element 40 is a coil spring, and placed between the two clasp portions 33 of the corresponding fastener 30. A diameter of each head portion 31 is greater than that of the shaft 32 and that of the through hole 121 of the handle 10, but is less than that of the through hole 231 of the retention portion 23.
Referring also to FIGS. 4-7, in assembly, the arms 12 of the handle 10 are inserted between the main body 20 and the retention portions 23 respectively, with the through holes 121 of the arms 12 aligning with corresponding through holes 231 of the retention portions 23. For simplicity, only one of the fasteners 30 is described herein. The shaft 32 of the fastener 30 together with its resilient element 40 extends through the through hole 231 of the corresponding retention portion 23, and the through hole 121 of the handle 10. The two clasp portions 33 extend through the access sections 241 of the two corresponding locking apertures 24. The resilient element 40 abuts against the main body 21 between the two locking apertures 24, and is compressed. Rotating the fastener 30 until the hooks 331 is in alignment with the locking slots 25, and then releasing the fastener 30. The resilient element 40 is restored, and urges the hooks 331 to be engagingly received in the locking slots 25. The head portion 31 is received in the through hole 231 of the retention portion 23.
When it is desired to detach the handle 10 from the main body 21, the fastener 30 is pressed inwardly, so that the hooks 331 leave the locking slots 25. Rotating the fastener 30 until the hooks 331 align with the access sections 241 of the locking aperture 24. The fastener 30 is pushed outwardly by the restoring force of the resilient element 40, so that the fastener 30 is readily to be taken out from the main body 21. The handle 10 is thus readily taken out from the main body 21.
It is believed that the present embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the example hereinbefore described merely being a preferred or exemplary embodiment.
