2. Description of the Related Art
In general, a “portable communication apparatus” refers to an electronic apparatus, which a user can carry with him to perform wireless communication with a desired partner. In consideration of portability, designs of such portable communication apparatuses tend to not only be compact, slim, and light, but also have greater multimedia availability, with a wider variety of functions. In particular, future portable communication apparatuses are expected to incorporate greater multi-functionality and multi-purpose utilization, as well as becoming even more compact and light, but also will be modified to be suitable for various multimedia environments or Internet environments. Additionally, such portable communication apparatuses are now commonly used by all kinds of people throughout the world and are recognized by some people as a nearly indispensable part of life.
Conventional portable communication apparatuses may be classified into various types according to their appearance, such as bar-type portable communication apparatuses, flip-type portable communication apparatuses, and folder-type portable communication apparatuses. In addition, portable communication apparatuses may be classified into neck wearable type communication apparatuses and wrist wearable type communication apparatuses according to the position at or the way in which a user puts on the communication apparatuses. Furthermore, portable communication apparatuses may be classified into swing-type communication apparatuses and sliding-type communication apparatuses according to ways of opening and closing the communication apparatuses. These variously classified portable communication apparatuses can be easily understood by those skilled in the art.
Meanwhile, conventional portable communication apparatuses now tend to have a function of transmitting data at a high speed in addition to the basic function of performing voice communication. In other words, according to the increase of demand by consumers, portable communication apparatuses now tend to provide a service using a wireless communication technology capable of transmitting data at a high speed.
According to current trends, conventional portable communication apparatuses are equipped with a camera lens to transmit video signals.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention unclear.
As shown in FIGS. 1 and 2, a sliding swing apparatus for use in a sliding swing type portable apparatus according to the present invention includes a base 10, first guide means (explained below) positioned on both sides of the base 10, a second guide means 20 positioned adjacent to the first guide means, a swing shaft 30 adapted to slide by means of the second guide means 20, a sliding plate 40 constrained by the first guide means and adapted to slide while continuously facing the base 10, a force supply means (not shown) positioned between the sliding plate 40 and the second guide means 20 to provide the sliding plate 40 with a sliding force; and a swing plate 50 adapted to swing while facing the sliding plate 40. The force supply means, which includes an elastic body and a rolling member (not shown in the drawings), will be described later in detail.
As shown in FIGS. 1 and 2, the swing plate 50 has a number of tension protrusions 51 to 54 to maintain tension between the sliding plate 40 and the swing plate 50. The swing plate 50 remains stationary on the sliding plate 40 and, if an external constant force larger than the tension is applied, swings while facing the latter at a first rotation angle. The tension protrusions 51 to 54 are made by pressing and bending predetermined parts of the swing plate.
The sliding plate 40 is adapted to slide along a pair of guide rods 15 and 16. The swing plate 50 proceeds to swing after completing a sliding movement on the sliding plate 40.
As shown in FIG. 1, the first guide means includes a pair of guide grooves 11 and 12 recessed from the base 10 the length of the sliding distance of the sliding plate 40 between its initial and final positions, a pair of guide rods 15 and 16 having both ends fixed by laser welding in such a manner that they traverse the pair of guide grooves 11 and 12, and a pair of fastening portions 41 and 42 made by bending both ends of the sliding plate 40 in such a manner they surround a predetermined length of the pair of guide rods 15 and 16 and adapted to slide along the pair of guide rods 15 and 16. The base 10 has fine holes formed adjacently to the pair of guide grooves 11 and 12 so that both ends of the pair of guide rods 15 and 16 can be welded thereto. The pair of guide grooves 11 and 12 extend linearly and provide the pair of fastening portions 41 and 42 with a space to move therein.
The second guide means 20 according to the present invention will now be described with reference to FIGS. 3 to 5. As shown in FIGS. 3 to 5, the second guide means 20 includes guide rails of light aluminum alloy material. Specifically, the guide means 20 includes a pair of first guide rails 210 and 220 formed on both lateral surfaces thereof, respectively, and a pair of second guide rails 230 and 234 formed on the upper surface thereof and positioned between the pair of first guide rails 210 and 220.
The first guide rails 210 and 220 have first stop grooves 212 and 222 for determining the initial position of the sliding plate 40, second stop grooves 218 and 228 for determining the final position of the sliding plate 40, first slant surfaces 214 and 224 gradually extending away from the first stop grooves 212 and 222 perpendicularly to the sliding direction, and second slant surfaces 216 and 226 gradually approaching the second stop grooves 218 and 228 from the first slant surfaces 214 and 224 perpendicularly to the sliding direction. Preferably, curved portions are formed between the first stop grooves 212 and 222 and the first slant surfaces 214 and 224, between the first slant surfaces 214 and 224 and the second slant surfaces 216 and 226, and between the second slant surfaces 216 and 226 and the second stop grooves 218 and 228, respectively, so that the sliding plate 40 can slide smoothly thereon.
In addition, rolling grooves 240 and 242 of a predetermined depth are continuously positioned between the first stop grooves 212 and 222 and the second stop grooves 218 and 228 in order to support the rolling guide movement of a rolling member which will be described later.
The second guide rails 230 and 234 include a first guide groove 236 recessed a predetermined depth from the upper surface thereof so that the swing shaft can slide therein and a second guide groove 235 recessed a predetermined depth from the first guide groove 236 to limit the swing motion of the swing plate during sliding. Both ends of the first guide groove 236 are of a semi-cylindrical shape, which corresponds to that of the swing shaft. The second guide groove 235 linearly extends for the length of the sliding distance.
The second guide rail 234 preferably has a circular opening 230 through which a flexible circuit (not shown) passes and a swing opening 232 formed along the outer periphery of the opening 230. The principle of operation of the swing opening 232 will be described later.
The construction of the swing shaft 30 according to the present invention will now be described with reference to FIG. 6. The upper end of the swing shaft 30 is integrated to the swing plate by laser welding. The swing shaft 30 has a stopper S formed on the lower end thereof and an opening formed in the opposite direction to the stopper S. As will be described later, the stopper S limits the amount of rotation of the swing plate 30 and prevents the swing movement during the sliding movement. A flexible circuit (not shown) passes through the opening. The lower end of the swing shaft 30 is guided to slide on the second guide groove 236.
A rotation limitation means of the swing shaft 30 according to the present invention will now be described with reference to FIGS. 3 and 6. When the swing shaft 30 and the swing plate 50 are assembled to each other, the stopper S of the swing plate slides along the second guide rail 234 as the sliding plate 40 slides.
When the sliding movement of the sliding plate 40 ends as shown in FIG. 9, the stopper S is positioned on an end 232a of the swing opening 232. As the swing plate is rotated, the stopper S is rotated to the other end 232b of the swing opening 232. As such, the rotational movement of the stopper S is guided by the swing opening 232, and this limits the rotation of the swing plate. It is to be noted that, although the length of the swing opening 232 along the outer peripheral direction is shown to correspond to a rotational angle of 90° in the drawing, the length may correspond to a different rotational angle.
A semi-automatic sliding force supply means according to the present invention will now be described with reference to FIGS. 7 to 8B. As shown in FIGS. 7 to 8B, the force supply means provides a stopping force in the initial position P1, a closing force within the region of P2, an opening force within the region of P3, and a stopping force in the final position P4.
Specifically, the force supply means includes a pair of elastic bodies 410 and 420 and a pair of rolling members 430 and 440 adapted to roll while sliding and continuously being forced against the first guide rails 210 and 220 by a force from the pair of elastic bodies 410 and 420. The pair of elastic bodies 410 and 420 are made of torsion springs. The torsion springs 410 and 420 have fixed ends 411 and 421 constrained by the sliding plate, free ends 413 and 423 adapted to be guided along the lateral surface of the first guide rails 210 and 220, and center portions 412 and 422 positioned between the fixed ends 411 and 421 and the free ends 413 and 423 and fixed at the sliding plate 40 to provide a predetermined trajectory according to the sliding movement. The rolling members 430 and 440 are provided on the free ends 413 and 423 and are adapted to roll on the rolling grooves 240 and 242 (shown in FIG. 5) formed on the lateral surface of the first guide rails 210 and 220. The rolling members 430 and 440 are made of light metallic material.
FIG. 10A shows a state before a sliding of the sliding plate (hidden by the swing plate 50). The rolling members are positioned in the first stop grooves 212 and 222 in FIG. 10A. FIG. 10B is a front view showing a state after a complete sliding of the sliding plate (hidden by the swing plate 50). The rolling members have passed through the first and second slant surfaces 214, 224, 216, and 226 are positioned in the second stop grooves 218 and 228 and the stopper (shown in FIG. 9) is positioned on an end of the swing opening in FIG. 10B. FIG. 11 is a front view showing a state after a complete swing of the swing plate. The stopper (shown in FIG. 9) has traveled along the swing opening and is positioned on the other end of the swing opening in FIG. 11.
The operation of the portable apparatus equipped with the sliding swing apparatus according to the present invention will now be described. As shown in FIGS. 12 and 13, the portable apparatus includes a body 1 and a sliding swing housing 2 adapted to travel on the body 1. The body 1 has a first keypad 6 adapted to be exposed/covered according to whether the sliding swing housing 2 has slid or not and a second keypad 8 adapted to be exposed/covered according to whether the sliding swing housing 2 has swung or not.
FIG. 12 shows a state after the sliding swing housing 2 has slid in a linear direction. The sliding swing housing 2 has linearly slid on the body 1 while continuously facing the latter. FIG. 13 shows a state after the sliding swing housing 2 has swung about 90°. The sliding swing housing 2 has swung on the body 1 while continuously facing the latter. The sliding swing housing 2 has a first speaker 3 device positioned on the upper surface thereof, a display device 5 positioned adjacently to the first speaker device 3, a third keypad 7 positioned adjacently to the display device 5, and a second speaker device 4 positioned adjacently to the third keypad 7. The first and second speaker devices 3 and 4 provide a stereoscopic sound.
It is convenient to watch a displayed screen, such as a TV or a video, in a state as shown in FIG. 13. This is because the display device 5, which displays a screen, and the first and second speaker devices 3 and 4 are positioned in such a manner that the displayed screen can be watched in a widescreen mode and listened to in stereo.
As mentioned above, the sliding swing apparatus according to the present invention makes it possible to watch the displayed screen in a stable and convenient manner in a TV or video-watching mode. In addition, it is possible to avoid the erroneous operation of the sliding swing housing and make the apparatus in a slim size by realizing a swing motion after a sliding movement.
While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
