  If the groove portion and the rail portion are engaged and the first and second housings are slid, there is a risk of galling. Specifically, when the second housing is slid to the maximum with respect to the first housing, the length of the rail portion that engages with the groove portion is shortened, and galling is likely to occur. In particular, in order to ensure the length of the slidable range, the length of the overlapping portion of the first and second housings when the second housing is slid to the maximum with respect to the first housing is reduced. If designed, galling is likely to occur.

  In order to improve the operability of the slide, it is desirable to have a mechanism for assisting the slide. The same applies when the first and second housings are slid using links.

  An object of the present invention is to provide a portable device in which sliding is assisted without galling.

  The portable device disclosed in the present specification includes first and second housings and a pair of link members, and the second housing is slidably connected to the first housing within a predetermined range. A link mechanism; and a biasing member that biases the second housing from a predetermined position in the slide range to one end or the other end of the slide range.

  A portable device in which sliding is assisted without galling can be provided.

For example, a display is provided on the front surface 22 of the movable body 20. For example, operation keys are provided on the front surface 12 of the main body 10. In the closed state, the front surface 12 of the main body 10 is concealed by the movable body 20. In the open state, the front surface 12 is exposed. The main body 10 and the movable body 20 are each substantially rectangular. The main body 10 and the movable body 20 have substantially the same shape. The movable body 20 is slidable in the short side direction with respect to the main body 10. The movable body 20 slides within a predetermined range with respect to the main body 10.

  2 to 4 are exploded perspective views of the mobile phone 1. FIG. 2 illustrates the cellular phone 1 in a closed state. FIG. 3 illustrates the mobile phone 1 in a state between a closed state and an open state. FIG. 4 illustrates the cellular phone 1 in an open state. 2 to 4 simply illustrate the main body 10.

  As illustrated in FIG. 2, a support plate 40, a spring 50, and link members 60 a and 60 b are provided between the main body 10 and the movable body 20. The link members 60a and 60b function as a parallel link mechanism that connects the movable body 20 to the main body 10 so as to be slidable within a predetermined range. The spring 50 biases the movable body 20 from a predetermined position in the slide range to one end or the other end of the slide range. The support plate 40 is fixed to the back side of the movable body 20. The support plate 40 supports the link members 60 a and 60 b with the movable body 20. The support plate 40, the spring 50, and the link members 60a and 60b are made of metal, for example.

  The link member 60 a includes an end portion 61 a connected to the main body 10 side and an end portion 62 a directly connected to the support plate 40. The end portion 61 a is rotatably connected to the main body 10. A hole is provided in the end portion 61a, and the pin 66a passes through the hole. The pin 66a is inserted into the hole 16a of the main body 10 or rotatably with respect to the link member short part 61a. The pin 66 a extends in the thickness direction of the main body 10. The pin 66a is made of metal. The hole 16 a is provided on the long side of the main body 10.

  The end 62a is rotatably connected to the support plate 40. The end 62a is provided with a hole, and the pin 42a passes through this hole and is joined to the support plate 40. Since the support plate 40 is fixed to the movable body 20, the end 62a is connected to the movable body 20 side. The end 62 a is connected to the approximate center of the short side of the support plate 40.

  The support plate 40 is provided with an escape hole 46a for escaping the movement of the pin 66a. The escape hole 46a has an arc shape. Thereby, the link member 60a can be rotated around the end portion 62a. The support plate 40 is fixed to the movable body 20 with screws or the like. The support plate 40 is provided with six screw holes although not denoted by reference numerals.

  The link member 60b has the same structure as the link member 60a. The pin 66b is inserted into the hole 16b through a hole provided in the end portion 61b. The escape hole 46b escapes the movement of the pin 66b. The end 62b is rotatably connected to the support plate 40 by a pin 42b.

  A spring 50 is connected between the link member 60 a and the support plate 40. The spring 50 includes a coil part 51, an arm part 56 a continuous with the coil part 51 and connected to the link member 60 a, and an arm part 56 b continuous with the coil part 51 and connected to the support plate 40. The arm portion 56a is connected to the end portion 61a of the link member 60a. The arm portion 56 b is connected to a protrusion 45 provided at a substantially central portion of the support plate 40. In the state shown in FIG. 2, the spring 50 biases the end 61 a away from the protrusion 45. The end portion 61 a is pressed against the end portion of the escape hole 46 a by the urging force of the spring 50. That is, in the state illustrated in FIG. 2, the urging force is applied by the coil portion 51 so that the angle between the arm portions 56 a and 56 b is widened.

  As illustrated in FIG. 3, the movable body 20 and the support plate 40 slide integrally with the main body 10. Thereby, the link members 60a and 60b rotate around the end portions 62a and 62b, respectively. The pins 66a and 66b move in the escape holes 46a and 46b, respectively. FIG. 3 illustrates a state in which the movable body 20 is located approximately at the center of the slide range. In the state illustrated in FIG. 3, the angle between the arm portions 56 a and 56 b is smaller than that in the state illustrated in FIG. 2. That is, between the states illustrated in FIGS. 2 to 3, the spring 50 urges the end portion 61a to return to one end of the escape hole 46a.

  As illustrated in FIG. 4, when the movable body 20 is further slid, the end portion 61a is pressed against the other end of the escape hole 46a. Between the states illustrated in FIG. 3 to FIG. 4, the spring 50 biases the end portion 61 a toward the other end of the escape hole 46 a. Therefore, when the cellular phone 1 is changed from the closed state to the open state, the movable body 20 is slid to the center of the slide range against the urging force of the spring 50 from the state illustrated in FIG. Thereafter, the sliding of the movable body 20 to the other end of the slide range is assisted by the biasing force of the spring 50.

  When the cellular phone 1 is changed from the open state to the closed state, the movable body 20 is slid to the center of the slide range against the biasing force of the spring 50 from the state illustrated in FIG. Thereafter, the sliding of the movable body 20 to one end of the slide range is assisted by the biasing force of the spring 50. As described above, the spring 50 assists the sliding of the movable body 20 from the approximate center of the slide range to one end or the other end of the slide range.

  Thus, the mobile phone 1 of the present embodiment connects the main body 10 and the movable body 20 so as to be slidable by the parallel link mechanism. For this reason, for example, there is no possibility of galling unlike a portable device in which a groove portion is provided on the first housing side and a rail portion slidably engaged with the groove portion is provided on the second housing side.

  Here, the caulking will be briefly described. A case is assumed in which a pair of groove portions that are parallel to each other and extend in a linear direction are provided in the first housing, and a pair of rail portions that are engaged with the pair of groove portions are provided in the second housing. When the first and second housings slide due to the engagement between the groove and the rail, a clearance is set between the groove and the rail. When the first and second housings are slid to the maximum extent, the length of the engaging portion between the groove and the rail is reduced. For this reason, a rail part will be in the state which tends to incline with respect to the direction where the groove part was extended. If the first and second housings are slid and returned to the original state in a state where the rail portion remains inclined with respect to the extending direction of the groove portion, the rail portion does not slide smoothly with respect to the groove portion. In this way, galling occurs. Therefore, the operability may be deteriorated.

  In particular, in order to ensure the area of the front surface of the second housing exposed by the slide, it is necessary to expand the slide range. In order to expand the slide range, it is necessary to shorten the length of the overlapping portion of the first and second housings when the first and second housings are slid to the maximum extent. In such a case, galling is more likely to occur. In order to provide many operation keys and a large display on the front surface of the second casing exposed by the slide, the larger the slide range, the better.

  In the mobile phone 1 of the present embodiment, since the main body 10 and the movable body 20 are slidably connected by the parallel link mechanism, the above-described problems are unlikely to occur. Further, as described above, the spring 50 assists the slide. This also improves the operability of the mobile phone 1.

  FIG. 5 is a cross-sectional view of the mobile phone 1. FIG. 5 shows a connection structure between the main body 10 and the link member 60b. The pin 66 b is inserted into the hole 16 b of the main body 10. A bearing 68b is inserted into the pin 66b. The pin 66b passes through the bearing 68b. The bearing 68b is inserted into the hole 16b so as not to rotate. The pin 66b is rotatable with respect to the bearing 68b. In this way, the end 61b of the link member 60b is rotatably connected to the main body 10. Note that the end portion 61a of the link member 60a is also rotatably connected to the main body 10 with the same structure.

  As described above, the pins 66 a and 66 b extend in the thickness direction of the main body 10 and are engaged with the main body 10. For this reason, the rigidity of the pins 66a and 66b can be ensured. Therefore, for example, even when an impact is applied to the mobile phone 1 in the open state and a load is applied to the pins 66a and 66b, the pins 66a and 66b can be prevented from being damaged.

  Further, when the first and second housings are slid to the maximum by the engagement between the groove and the rail, it is necessary to secure a certain area of the overlapping portion from the viewpoint of preventing damage. However, in the mobile phone 1 of the present embodiment, the main body 10 and the movable body 20 are connected by the pins 66a and 66b. Therefore, the area occupied by the holes 16a and 16b with respect to the front surface 12 of the main body 10 may be small as compared with the case of sliding due to the engagement between the groove portion and the rail portion. Thereby, the exposed area of the front surface 12 can be ensured.

  The holes 16a and 16b are provided along the long side of the main body 10 as illustrated in FIGS. For this reason, the area of the part which the main body 10 and the movable body 20 overlap in an open state can be made small. Thereby, the area of the front surface 12 of the main body 10 exposed in the open state can be ensured.

  As described above, the link members 60 a and 60 b are disposed between the movable body 20 and the support plate 40. Thereby, the link members 60a and 60b are protected. Further, the link members 60 a and 60 b are prevented from being exposed from the back surface of the movable body 20 in the open state.

  As illustrated in FIGS. 2 to 4, the spring 50 is always concealed between the movable body 20 and the support plate 40. This prevents the spring 50 from being exposed to affect the appearance of the mobile phone 1.

  As illustrated in FIGS. 2 and 4, the movable ranges of the link members 60a and 60b are limited by the end portions 61a and 61b coming into contact with the end portions of the escape holes 46a and 46b, respectively. Therefore, the relief holes 46 a and 46 b of the support plate 40 have a function of defining the slide range of the main body 10 and the movable body 20.

  Although not shown, the wiring connecting the main body 10 and the movable body 20 can be prevented from being caught by the link member 60a or the link member 60b by wiring the link member 60a or the link member 60b.

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims.・ Change is possible.

  The mobile device is not limited to a mobile phone. For example, the portable device may be a PDA or a notebook computer.

  The arm portion 56 a of the spring 50 may be directly connected to the main body 10, and the arm portion 56 b may be directly connected to the movable body 20. In this case, it is desirable that the end portion of the arm portion 56a of the spring 50 is connected at a portion where the main body 10 and the movable body 20 always overlap. The support plate 40 may not be provided.

  The main body 10 may be provided with a display, and the movable body 20 may be provided with operation keys. A display may be provided on both the main body 10 and the movable body 20. Operation keys may be provided on both the main body 10 and the movable body 20.

  The support plate 40 may be provided with a notch for escaping the movement of the pin 66b.

  The first and second housings may be portable devices that slide in the long side direction.
