This application claims priority under 35 U.S.C. § 119 to an application entitled “Portable Cradle” filed with the Korean Intellectual Property Office on Feb. 22, 2006 and assigned Ser. No. 2006-17370, the contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a portable terminal including Digital Multimedia Broadcasting Phones (DMB phone), game phones, camera phones, cellular phones, Personal Digital Assistants (PDAs), Hand Held phones and the like, and in particular, to a folding type portable cradle which can be conveniently carried along with accessories for a portable terminal.
2. Description of the Related Art
In general, a “portable terminal” refers to an electronic device which a user can conveniently carry while wirelessly communicating with another user. In consideration of portability, design of such a portable terminal has gravitated towards compactness, slimness and lightweight design, as well as towards providing multimedia capabilities for allowing the user to pursue a wider variety of functions. In particular, future portable terminals will be used for many functions while still remaining compact and light, as well as being modified to be suitable for functioning in a multimedia environment and for providing Internet access and functions.
Conventional portable terminals can be classified into various types according to their appearance, such as bar-type portable terminals, flip-type portable terminals, and folder-type portable terminals. Further, portable terminals can be classified as neckwear-type terminals and wristwear-type portable terminals, according to the position at which or the way in which a user wears the terminal. Additionally, portable terminals can be classified as rotation-type terminals and sliding-type terminals according to the manner of opening and closing the portable terminals. The various classifications of portable terminals are easily understood by those skilled in the art.
It is now common practice to watch various motion pictures through the portable terminal in a DMB mode and to enjoy entertainment, such as various games, in a multimedia environment by using the portable terminal. However, the conventional portable terminal has no separate cradle, thereby making it inconvenient to watch various motion pictures in the DMB mode when it is located on a desk, etc. Although vehicles have a separate cradle for making it possible to cradle the portable terminal, there exists no cradle, which can be used anytime, and anywhere.
Conventionally, a cradle for the portable terminal is also used as a charger. That is, a charging cradle is used for charging the portable terminal. A conventional charger charges electricity to the portable terminal which is vertically or slantingly cradled in the charger. However, since such a charger is adapted to only one type of the portable terminal, it cannot be used as a cradle for another type of the portable terminal. Additionally, the charger cannot be easily carried as an accessory in order to cradle the portable terminal. Particularly, the total size of the charger is large making it impossible to easily carry the charger as an accessory. Therefore, there is required a portable cradle which has a function of simply cradling the portable terminal.
Further, the conventional cradle has a structure in which the portable terminal can be cradled in the cradle, not in a landscape mode, but in only portrait mode. Actually, it is preferred for a user to selectively keep a display unit in a portrait mode or a landscape mode, so as to watch images displayed on a display unit.

As shown in FIGS. 1 to 4, a cradle 100 for a portable terminal according to the present invention is a portable and foldable device, i.e. an accessory having a smaller size than that of the portable terminal and can be easily carried along with the portable terminal. Specifically, the cradle 100 according to the present invention is a device capable of providing the most suitable multimedia environment to the portable terminal in the future, especially providing convenience to a user in a DMB mode or TV mode. The cradle 100 according to the present invention includes a housing 1, and first and second cradle bodies 2 and 3 which are received in the housing 1 and which rotate to be spaced far apart or to approach each other.
The housing 1 can have an open space for receiving either a portion or all of the first and second cradle bodies 2 and 3 respectively. Further, the housing 1 has two hinges, i.e. first and second hinges H1 and H2, in which the first hinge H1 is disposed in the housing 1 and is rotatably connected to the first cradle body 3 and the second hinge H2 is disposed in the housing 1 and rotatably connected to the second cradle body 3. The first and second hinges H1 and H2 are spaced apart, which provide first and second hinge axes A1 and A2, which are parallel to each other, to the first and second cradle bodies 2 and 3, respectively.
The first cradle body 2 is fully received in the housing 1, or separated from the housing 1 so as to support the cradled portable terminal along with the housing 1, according to the rotation thereof. Specifically, the first cradle body 2 is separated from the housing 1 so as to be inclined relative to the ground surface. FIG. 1 shows the first cradle body 2 fully received in the housing 1, while FIGS. 2 to 4 show the first cradle body 2 in a rotated state and separated from the housing 1. The housing 1 serves to receive all of the first and second cradle bodies 2 and 3 so as to protect them from the exterior circumstance. The first cradle body 2 is rotatable by a predetermined angle so as to be inclined to support the portable terminal.
Specifically, the first cradle body 2 has a plate shape, which can be separated into two portions, such as a cradling portion 21 and a supporting portion 22. The cradling portion 21 is located at the front portion of the housing 1 after the first cradle body 2 rotates by the predetermined angle. A supporting portion 22 is located at the rear portion of the housing 1 so as to support the second cradle body 3.
The cradling portion 21 includes a holding unit 23 which stably holds the portable terminal placed on the upper surface of the first cradle body 2 thereof. Specifically, the holding unit 23 is located on the upper surface of the first cradle body 2, so as to be located at the front portion of the housing 1 or to be received in the housing 1. The holding unit 23 extends parallel to the first hinge axis A1 of the first hinge H1. The holding unit 21 is always exposed to the exterior, regardless of the rotation of the first cradle body 2.
Further, the holding unit 23 is located at the front portion of the housing 1 when the first cradle body 2 rotates, so as to stably hold the portable terminal cradled therein. Preferably, the holding unit 23 has a plurality of protrusion and depression portions. The protrusion and depression portions 23 include alternately arranged protrusion portions and depression portions. The protrusion and depression portions 23 have a wave like shape having greater height and depth at the front portion than those at the rear portion of the first cradle body 2. The height and depth of the protrusion and depression portions 23 decrease less and less from the front portion to the rear portion of the first cradle body 2. This is in order to positively cope with the inclination of the first cradle body 2. Further, the holding unit 23 is made of an elastic material, in order to stably support the portable terminal placed thereon. Preferably, the elastic material includes a rubber and a synthetic resin material such as silicon material or urethane material.
The second cradle body 3 may be fully received in the housing 1 or exit from the housing 1 by means of the second hinge H2, so as to be supported against the ground surface. Further, the second cradle body 3 supports the first cradle body 2 which is inclined, so as to allow the end of the supporting portion 23 of the first cradle body 2 to slide along the second cradle body 3. Accordingly, the inclination of the first cradle body 2 can be adjusted. The second cradle body 3 is further provided with guide units 31 and 32 for a stable sliding of the first cradle body 2, and members 33 used for adjusting the inclined angle of the first cradle body 2.
The guide units 31 and 32 include a pair of guiding bars, which are arranged at the rear portion of the second cradle body 3. Further, the guide units 31 and 32 linearly protrude at the rear portion on the upper surface of the second cradle body 3, so as to stabilize the sliding movement of the first cradle body 2.
The members 33 used for adjusting the inclined angle are arranged between the guide units 31 and 32, so as to support the first cradle body 2 in order to maintain the inclination of the first cradle body 2.
Referring to FIGS. 1 to 3, the rotation movement of the first and second cradle bodies 2 and 3 will now be described. In the state shown in FIG. 1, when a user pushes the supporting portion 22 of the first cradle body 2 in a direction marked by an arrow {circle around (1)}, the housing 1 rotates and ascends in a direction marked by an arrow {circle around (2)}, the cradling portion 21 of the first cradle body 2 rotates in a direction marked by an arrow {circle around (3)}, and the second cradle body 3 and the supporting portion 22 (as shown in FIGS. 2 and 4) of the first cradle body 2 descends in a direction marked by an arrow {circle around (4)}, as shown in FIG. 2. These movements are simultaneously performed.
Next, in the state shown in FIG. 2, if the user intends to make the first cradle body 2 more inclined, the user rotates and lifts the housing 1 in a direction marked by an arrow {circle around (5)}. At the same time, the cradling portion 21 (as shown in FIGS. 2 and 4) is further rotated in a direction marked by an arrow {circle around (6)} while the rear end of the second cradle body 3 is linearly moved in a direction marked by an arrow {circle around (7)}.
Specifically, with the rotation movement of the first cradle body 2, the cradling portion 21 of the first cradle body 2 in the initial state of facing the second cradle body 3 is rotated in a direction of being apart from the second hinge H2 so as to be located at the front portion of the housing 1. Further, the supporting portion 22 of the first cradle body 2 in the initial state of facing the second cradle body 3 is rotated in a direction of being apart from the housing 1 so as to be located at the rear portion of the housing 1. On the other hand, with the rotation movement of the second cradle body 3, the second cradle body 3 in the initial state of facing the first cradle body 2 is rotated in a direction of being apart from the first hinge H1 so as to be located at the rear portion of the housing 1. Relatively, the housing 1 in the state of facing the first and second cradle bodies 2 and 3 is rotated in a direction of being apart from the second cradle body 3, so that the cradling portion 21 of the first cradle body 2 gradually protrudes in the front portion of the housing 1 at the same time when the housing 1 rotates, and the supporting portion 22 moves apart from the housing 1 more and more.
The first cradle body 2 is provided with a pair of protrusion 221 which is formed at the rear end of the first cradle body 2, so as to smoothly slide between the guide units 31 and 32.
Further, the portable cradle according to the present invention can be made of light synthetic resin so as to have various colorful appearances, and used as a fashionable accessory when a user carries it along with a portable terminal.
