ABSTRACT:

This application incorporates by reference Taiwanese application Serial No. 089212579, filed Jul. 20, 2000.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates in general to a cradle, and more particularly to a cradle capable of receiving objects having alternative sizes.
2. Description of the Related Art
The hand-held computer for commercial or personal purpose typically functions as a cellular phone, fax sender, and personal organizer. Users can easily get information on demand due to the portability, compactness and friendly interface of the hand-held computers. Besides, various accessories to the hand-held computer are designed to create additional functionality.
For example, the jacket is an accessory, which not only provides good protection but also makes the hand-held computer more flexible. Users can add a PCMCIA (Personal Computer Memory Card International Association) card or CF (Contact Flash) card to the hand-held computer for additional functionality by inserting the interface card into the jacket to satisfy their individual need. Thus, a hand-held computer with a jacket has become an alternative choice for consumers.
However, the hand-held computer with a jacket is bigger than that without a jacket. This prevents the additional functionality of the jacket from being efficiently used, since the jacket needs to be taken off while the hand-held computer is placed on the cradle. Besides, the hand-held computer can be harmed by taking off the jacket repeatedly.
If the cradle is designed for the hand-held computer with a jacket, a negative effect of the battery charging quality or data transmission may result by simply placing the hand-held computer without a jacket on the cradle due to the unsteady connection.
SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide a cradle capable of firmly receiving objects having alternative sizes to avoid the negative effect of battery charging quality or data transmission due to unsteady connection. The bi-directional data transmission can be proceeded by connecting with a computer host and the battery charging of the object can be proceeded by plugging in.
The invention achieves the above-identified objects by providing a cradle capable of receiving objects having alternative sizes. The cradle includes a main unit, a slide mechanism and a lock mechanism. The main unit loads and holds the object. The slide mechanism has two slide members, which move along the insides of the arc blades of the body upwards or downwards, for adjusting the size of the room for receiving the objects. The lock mechanism positions the slide mechanism by clasping the slide mechanism. The port connected with the computer host for bi-directional data transmission with the objects and the socket plugged in for battery charging of the objects are disposed on the rear side of the body.
