## Title
Portable computer and docking station locking structure

## Abstract

A portable computer and docking station locking structure in which the docking station has a lock provided inside the support arm thereof controlled by a key or the like, and the portable computer has a lock hole in the back side adapted to receive the swivel locking member of the lock for enabling the portable computer to be locked to the docking station after setting of the portable computer in the support arm of the docking station.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a portable computer and docking station locking structure and, more particularly to such a portable computer and docking station locking structure, which has lock means for locking the portable computer to the docking station after positioning of the portable computer in the docking station.
2. Description of Related Art
A portable computer, for example, a tablet PC (personal computer) may be used with a docking station, which has a support arm for holding the tablet PC in a tilted position for operation.
However, a conventional docking station does not have any lock means to lock the portable computer, i.e., the portable computer is simply placed on the docking station for operation and can be carried away from the docking station freely when desired. Because the portable computer is not locked to the docking station, it can easily be taken away from the docking station by someone unlawfully.
SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a portable computer and docking station locking structure, which enables the user to lock the portable computer to the docking station, preventing other people from taking the portable computer away from the docking station.
To achieve this and other objects of the present invention, the portable computer and docking station locking structure comprises a docking station and a portable computer. The docking station comprises a base, and a support arm provided at a top side of the base. The support arm has a supporting face disposed at the front side thereof and a holding groove disposed at the bottom side of the supporting face. The portable computer is positioned in the holding groove of the support arm, and rested on the supporting face.
The main feature of the present invention is that a lock is provided inside the support arm. The lock comprises at least one locking member controlled to protrude outside the supporting face. Further, the portable computer has at least one lock hole formed in the back side thereof adapted to receive the at least one locking member of the lock when protruded.
The portable computer can be a tablet PC. The lock can be a swivel lock controlled by a key, or a magnetic lock controlled by the portable computer or an external computer through a code.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an elevational view of the present invention, showing the portable computer supported on and locked to the docking station.
FIG. 2 is an exploded view of the portable computer and docking station locking structure according to the present invention.
FIG. 3 is an enlarged view of the lock shown in FIG. 2.
FIG. 4 is a schematic drawing showing an alternate form of the lock according to the present invention.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, a portable computer 2 is supported on a docking station 1. The portable computer 2 according to this embodiment is a tablet PC.
Referring to FIGS. 2 and 3 and FIG. 1 again, the docking station 1 comprises a base 11, and a support arm 12. The support arm 12 is provided at the top side of the base 11, having a supporting face 121 disposed at the front side and a holding groove 122 disposed at the bottom side of the supporting face 121. The portable computer 2 is positioned in the holding groove 122 of the support arm 12 of the docking station 1 and rested on the supporting face 121 of the support arm 12.
Further, a lock 3 is provided inside the support arm 12. According to this embodiment, the lock 3 is a swivel lock comprising a spindle 31. The locking member 32 is a hook radially extended from the front end of the spindle 31 for synchronous rotation with the spindle 31, and controlled to protrude outside the supporting face 121 of the support arm 12. The portable computer 2 has a lock hole 22 in the back side 21 adapted to receive the locking member 32 of the lock 3 when protruded.
After the portable computer 2 has been set in the docking station 1, the user can use the key 4 to rotate the spindle 31 of the lock 3 and to further force the locking member 32 into engagement with the lock hole 22, keeping the portable computer 2 locked to the docking station 1.
FIG. 4 shows an alternate form of the lock. According to this embodiment, the lock, referenced by 6, has two reversed locking members 61. Rotating the key, referenced by 7, in the lock 6 causes the locking members 61 to be moved inwards or outwards in the lock hole 22 of the portable computer 2 (see also FIG. 2) in reversed directions between the locking position and the unlocking position.
The lock for the portable computer and docking station locking structure may be variously embodied. A magnetic lock may be used as a substitute, and controlled by the portable computer through a code. Alternatively, the magnetic lock can be controlled by an external computer.
A prototype of portable computer and docking station locking structure has been constructed with the features of FIGS. 1 ̃4. The portable computer and docking station locking structure functions smoothly to provide all of the features discussed earlier.
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 invention. Accordingly, the invention is not to be limited except as by the appended claims.
