Typically, the term "portable terminal" means an electronic appliance which enables a user, who carries the portable terminal, to have cordless communication with a counterpart. To increase portability, such portable terminals are being miniaturized, slimmed, narrowed and lightened, and are also tending toward multi-media which can seek various functions. Therefore, it is expected that portable terminals will continue to be miniaturized and made light-weight. The devices will be used multifunctionally and multipurposely, and will be modified to be adaptive for various multimedia and Internet circumstances. In addition, such portable terminals are electronic appliances, which are popularly used by male and female, old and young all over the world and considered as necessities which should be always carried.
The first hinge base 101 is fixed on the first housing 201 of the portable terminal 200 (see FIG. 2). In order to fix the first hinge base 101, a cylindrical hinge arm 215, which is extended in the direction of the first hinge axis A1 is formed in the first housing 201. The first hinge base 101 is received and fixed in the hinge arm 215. The first hinge base 101 is fixed within the hinge arm 215 by a screw or other fastening system as can be easily embodied by one skilled in the art. Therefore, detailed description thereof is omitted.
At this time, the first connection shaft 103 sequentially passes through the spring member 163, the second hinge member 162, and the first hinge member while passing through the second hinge base 102, and then the first connection shaft 103 is fixed to the first hinge base 101. Therefore, the spring member 163 is assembled on the peripheral surface of the first connection shaft 103. Specifically, spring member 163 is on a cylindrical part 133 of the shaft and as described later is wound around the cylindrical part 133. The second hinge member 162 is assembled to be linearly movable within the second hinge base 102 and linearly movable and rotatable on the first connection shaft 103. Because the fist hinge member 161 and the first connection shaft are both fixed to the first hinge member 101, the first hinge member 161 and the first connection shaft 103 are retained in a stationary position with respect to one another.
These actions between the spring member and the hinge members can be more easily understood from U.S. Patent No. 6,292,980 , which was filed in the name of the present applicant filed and issued on September 25, 2001.
The support part 131 of the first connection shaft 103 is formed with a first escaping groove 137 and a guide groove 139 as shown in FIG. 3. The first escaping groove 137 and the guide groove 139on the first connection shaft 103 are provided so as to configure a cooperative arrangement between the first connection shaft 103 and the second connection shaft 104 shown in FIGS. 1 and 5. The cooperative arrangement between the first and second connection shafts 103 and 104 will be described below in detail with reference to FIGS. 5 to 7.
FIG. 7 shows a state in which the second hinge base 102 rotate about the first hinge axis A1 and the second connection shaft 104 swivels around the first hinge axis A1 from the position shown in FIG. 5. If the hinge base 102 rotates about the hinge axis A1 from the position in which the first and second escaping grooves 137 and 147 engage each other, the second connection shaft 102 swivels around the first hinge axis A1, and the second escaping groove 147 is moved in the circumferential direction of the support part 141 in the state of wrapping the peripheral surface of the support part 141.
Meanwhile, when the second housing 202 rotates about one of the first and second hinge axes A1 and A2, the rotation of the second housing 202 about the other hinge axis can be limited merely by the arrangement of the guide groove 139 and the guide projection 149. For example, if the first and second escaping grooves 137 and 147 are not formed but the first and second hinge axes A1 and A2 are spaced from each other to such an extent that the support part 131 and the rotating part 141 do not interfere with each other, the first and second escaping grooves 137 and 147 are not required and the above-mentioned rotation can be limited merely by the arrangement of the guide groove 139 and the guide projection 149.
If the support part 131 and the rotating part 141 do not interfere with each other, they are arranged in such a way that the guide projection 149 interferes with the peripheral surface of the support part 131 when the second connection shaft 104 has been rotated about the first hinge axis A1. If the second guide projection 149 interferes with the peripheral surface of the support part 131, the rotation of the second connection shaft 104 about the second hinge axis A2 is limited.
wherein the hinge device limits the rotation of the second housing about the second hinge axis when the second housing has been rotated about the first hinge axis to the open position, and the hinge device limits the rotation of the second housing about the first hinge axis when the second housing has been rotated about the second hinge axis to the open position.
