Description

PRIORITY

This application claims priority to an application entitled “CRADLE FOR PORTABLE COMMUNICATION DEVICE” filed with the Korean Intellectual Property Office on May 20, 2005 and assigned Serial No. 2005-42726, the contents of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cradle for a portable communication device in which a sticking prevention member is provided between a support member and an absorption plate.

2. Description of the Related Art

In general, “portable communication device” refers to an electronic device that a user can carry to perform wireless communication with a desired partner. The portable communication device refers to a hand-held phone (HHP), a CT-2 cellular phone, a digital phone, a personal communication system (PCS) phone, and a personal digital assistant (PDA). For example, radio terminals may be classified into various categories according to their appearance, such as a bar-type radio terminal, a flip-type radio terminal, and a folder-type radio terminal. A bar-type radio terminal is a device having a single bar-shaped housing. A flip-type portable communication device is a device in which a flip or a cover is rotatably mounted to a bar-shaped housing by a hinge unit. A folder-type communication device refers to a manner in which a folder is rotatably connected to a single bar-shaped housing by a hinge unit.

The portable communication device necessarily includes an antenna device, a data input/output device, and a data transmitting/receiving device. The data input device generally includes a key pad with which data are inputted by pressing with a finger, and can include a touch pad or a touch screen. The data output device generally includes a liquid crystal display (LCD) to display data.

Recently, it has become possible to watch moving pictures and TV, and play a game using a portable communication device. Further, the portable communication device can be mounted to a vehicle to use a function by which moving pictures, a game, and TV can be watched in addition to a talking function thereof.

In order to use the portable communication device for such a purpose, a cradle for a vehicle is needed to fix a separate terminal. The cradle for a vehicle is attached at a predetermined position of the interior of the vehicle to use conveniently in the state in which the terminal is engaged with the cradle, so that a driver does not have to hold the portable terminal while driving the vehicle.

However, since the cradle for the portable communication device is fixed to a dashboard or a predetermined position of the vehicle by using screws and/or an adhesive, after the cradle has been installed to the vehicle, it cannot be moved and installed again at a different place without leaving traces of the adhesive and the screws at the former position. In order to avoid this problem, an absorption member which can be attached and detached easily is used. In this case, the pressure in the absorption member is lowered and a restoring force is generated, thereby performing the absorption, by pulling a central portion of the absorption member and extending the absorption member entirely or partially. However, the structure using the absorbing force has problems in that the absorption member may become stuck to the vehicle due to vibrations, temperature, and changes in humidity, lowering the absorbing operation of the cradle, and a concentrated force may be applied to the absorption portion locally over time, introducing air through an aperture formed by the concentrated force and lowering the absorbing force.

SUMMARY OF THE INVENTION

Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a cradle for a portable communication device which provides a uniform pressing force, thereby improving the pressing force of the cradle.

Another object of the present invention is to provide a cradle for a portable communication device which includes a sticking prevention member between a support member and an absorption plate to prevent the support member and the absorption plate from sticking to each other due to an external environment after the cradle is mounted for a long time.

In order to accomplish these objects, there is provided a cradle for a portable communication device, which includes a support member; an absorption plate engaged with a lower portion of the support member; a pressing lever provided at an upper portion of the support member and pressing the absorption plate by pressing and moving the support member as the pressing lever is rotated about a hinge axis; a rotation means provided on the hinge axis and rotatably engaging the pressing lever with the absorption plate; and a sticking prevention member provided between the support member and the absorption plate, for preventing the support member and the absorption plate from sticking to each other when the support member and the absorption plate are pressed together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a cradle 10 of a portable communication device includes a support member 20, an absorption plate 30, a pressing lever 40, a rotation means 50, and a sticking prevention member 60. The absorption plate 30 preferably has a suction cup type construction and is engaged with the lower portion of the support member 20 so as to be attached at a predetermined position of a vehicle. The pressing lever 40 is rotatably engaged with one end of a center hinge member 52 formed in the rotation means 50. The pressing lever 40 is provided at the upper portion of the support member 20 SO that the support member 20 is pressed and moved in the axial direction of the center of the support member 20 and the absorption plate 30 is pressed as the pressing lever 40 is rotated about a hinge axis A1 of the rotation means 50. The rotation means 50 engages the pressing lever 40 rotatably with the absorption plate 30. The sticking prevention member 60 is provided between the support member 20 and the absorption plate 30.

As shown in FIG. 2, the rotation means 50 includes a pair of side hinge members 51 and a center hinge member 52. The side hinge members 51 are formed in the pressing lever 40 so as to be rotatably engaged with the center hinge member 52 about the hinge axis A1. The center hinge member 52 protrudes from the central portion of the absorption plate 30 so that the side hinge members 51 are rotatably engaged therewith about the hinge axis A1.

A protrusion hole 21 is formed at the central portion of the support member 20 so that the center hinge member 52 penetrates and protrudes there though. Further, a penetration hole 61 is formed at the central portion of the sticking prevention member 60 so that the center hinge member 52 penetrates and protrudes there though.

As shown in FIGS. 2, 4 and 5, an engagement tube 22 is formed in the support member 20 so as to be engaged with the connection member 3 connected to a cradle member 2 of the portable terminal 1.

Further, as shown in FIG. 1, a pressing portion 41 is formed in the pressing lever 40 so that it presses against a pressing surface 23 formed in the support member 20 when the pressing lever 40 is rotated. A pressing force causes the absorption plate 30 to press against a surface, such as glass, to secure the cradle to the vehicle. Sticking prevention member 60 keeps absorption plate 30 separated from support member 20.

As shown in FIGS. 1-3, the sticking prevention member 60 is formed of a nonwoven fabric to prevent the support member 20 and the absorption plate 30 from sticking to each other. Prominences and depressions are formed on both surfaces of the sticking prevention member 60 to prevent the support member 20 and the absorption plate 30 from sticking to each other even after the support member 20 and the absorption plate 30 are pressed together for a long time.

Hereinafter, the operation of the cradle for a portable communication device according to the preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5.
