Description

  According to the present invention, a second casing provided with a display unit on the upper surface with respect to a first casing having an operation unit on the upper surface is slid in the front-rear direction or rotated in the horizontal direction by a simple operation, thereby displaying the display. The present invention relates to a switchgear suitable for use in a portable device that can be used vertically and horizontally, and a portable device using this switchgear.

  A mobile phone, which is a type of mobile device, includes a first housing having an operation unit such as a keyboard on the top surface and a second housing having a display unit such as an LCD on the top surface. A closed state in which the housing and the second housing overlap so that the upper surface of the first housing is covered by the second housing, and the second housing and the first housing are slid relative to each other in the front-rear direction. One with an open / close device that creates an open state that exposes the upper surface of one housing is on the market.

  In recent years, mobile phones with various functions such as a function using a communication line such as the Internet, a digital camera function, a recording / playback function, a television reception function, a game function, etc. in addition to a call function are on the market. Beyond just a telephone, it can be called a portable device. For this reason, for example, when a moving image of a television is particularly displayed on the display unit and the moving image is viewed, it is more suitable to use the second housing in a landscape orientation than in the first housing. Yes.

  By the way, some conventional mobile phones perform the opening operation by rotating the first casing and the second casing in the vertical direction with respect to each other. Has been proposed (see, for example, Patent Literatures 1 and 2). These cellular phones described in Patent Documents 1 and 2 include a first housing having an operation unit such as a keyboard on the upper surface, a second housing having a display unit and the like on the lower surface, and the second housing. And a third housing that supports the body to be openable and closable and rotatable. In this cellular phone, when the cellular phone is in a closed state when it is in use, the first casing and the second casing are overlapped and the top surface of the first casing is covered with the second casing. When the mobile phone is used from this closed state, the operation unit on the first casing is moved by rotating the second casing in the vertical direction via the third casing with respect to the first casing. Since the display unit is exposed and exposed to the outside at the same time, the display unit can be used (vertically opened state). At this time, the display unit is vertically long with respect to the first housing. When the display unit is used in landscape orientation, the display unit is in landscape orientation (horizontal open state) by rotating the vertically long second housing 90 degrees with respect to the third housing. Can be used horizontally.

  The mobile phone described in Patent Documents 1 and 2 can use the display unit provided in the second casing in both portrait and landscape orientations. However, when the display unit is used in landscape orientation, On the other hand, the second housing must be rotated vertically through the third housing, and then the second housing must be rotated 90 degrees with respect to the third housing. there were. When the display unit is closed after being used in landscape orientation, the second housing is rotated by 90 degrees with respect to the third housing, and then the second housing is moved with respect to the first housing. It has to be rotated in the vertical direction via the opening, and the closing operation is troublesome even when closing. Furthermore, in addition to the first housing and the second housing, a third housing is required, and the number of parts is large, and the thickness of the mobile phone increases accordingly.

Therefore, in order to solve such problems, the present applicant has proposed an opening / closing device that can be easily opened and closed with a small number of parts (see Patent Document 3). The opening / closing device is configured to slide the second casing and the first casing relative to each other in the vertical direction from the closed state in which the first casing and the second casing overlap with each other. Is exposed so that the operation portion can be operated, and at the same time, the display portion provided in the second housing can be used in a vertically long state, and the second housing is horizontal with respect to the first housing. The display portion of the second housing can be used in a landscape orientation by sliding in the horizontal direction while rotating in the direction. As described above, when the display unit is used horizontally, it can be performed by a simple operation by simply rotating the second housing in the horizontal direction while rotating the second housing in the horizontal direction. What can be opened and closed is desired.

  In FIGS. 3 and 8 to 10, an instruction symbol 7 shows a rotation having a substrate portion 7 a and engaging portions 7 b and 7 b having a substantially U-shaped cross section formed on both sides of the substrate portion 7 a. The reference plate 8 is a fixed base plate to which the rotary base plate 7 is rotatably attached. Both of them have a substantially rectangular shape, for example, made of SUS and have a rectangular shape. The fixed base plate 8 has a recess 2c provided on the operation portion 2a on the upper surface of the first housing 2 by means of a mounting screw 5. The shaft 9a is inserted into the guide long hole 8a provided in the substantially central portion of the fixed base plate 8 and is further engaged with the flange 9b. A shaft 9 is provided, and the insertion hole 7c is inserted and locked so that the rotation base plate 7 can rotate on the side where the rotation support shaft 9 penetrates the guide long hole 8a. That is, the rotating base plate 7 is rotatably supported on the fixed base plate 8 via the rotating support shaft 9. The rotation base plate 7 includes a rotation guide portion 7f having a planar chevron shape adjacent to the insertion hole 7c, and a pair of slide guide portions 7g and 7g provided symmetrically on both sides of the rotation guide portion 7f. A guide groove 7d is provided. In the engaging portions 7b and 7b of the rotating base plate 7, slide promoting members 10 and 10 having a substantially U-shaped cross section are inserted and fixed.

  Next, what is indicated on the upper side of the rotation base plate 7 and indicated by an instruction symbol 11 is a slide member, and what is indicated by an instruction symbol 12 on the upper side of the slide member 11 is a fixed member. Both of them have substantially the same size, for example, a flat, substantially rectangular shape made of SUS. Among these, the fixing member 12 is attached to the lower surface of the second housing 3 via a mounting screw (not shown). In a state where the slide member 11 is overlapped with the lower surface of the fixing member 12, it is fixed by superposition via spot welding or a mounting screw (not shown). The polymerization fixing means is not limited. You may use together an engaging means. In the illustrated example, as shown in FIG. 8, the fixing member 12 is fixed to the second housing 3 by an engagement piece 12b provided at one end portion and an attachment portion 12c provided with an attachment hole provided at the other end portion. Means are formed. The slide member 11 has a substrate portion 11a and rail portions 11b and 11b formed by bending both side portions of the substrate portion 11a in the longitudinal direction, and slide promotion is performed by attaching the rail portions 11b and 11b to the rotating base plate 7. By being inserted into the members 10, 10, it can be slid relative to the rotating base plate 7. The slide facilitating members 10 and 10 are fixed to the engaging portions 7b and 7b of the rotating base plate 7 by means of, for example, uneven fitting, and between the upper surface of the rotating base plate 7 and the lower surface of the sliding member 11. In particular, as shown in FIG. 10, a gap a is formed by the thickness of the slide promoting members 10 and 10 and the rail portions 11b and 11b formed by bending both side portions of the substrate portion 11a.

  The slide member 11 is provided with a flexible cable (not shown) that electrically connects the first housing 2 and the second housing 3 in a shape perpendicular to the longitudinal direction from the center to the near side in the longitudinal direction. A first rotation having an insertion hole 11c to be inserted, and a mountain-shaped rotation guide portion 7f provided in the rotation base plate 7 and slide guide portions 7g and 7g provided symmetrically from both sides of the rotation guide portion 7f. A guide groove 11f is formed of a second rotation guide groove 11d having a flat circular bow shape facing the guide groove 7d in a plan view and a rotation restricting guide groove 11e having an arrow in the second rotation guide groove 11d. Is provided. The slide member 11 attached to the lower surface side of the second housing 3 is provided with a guide recess 12a having an arrow shape with a wide plane so as to cover the rotation restricting guide groove 11e. A guide pin 13 attached to the fixed base plate 8 is inserted into the first rotation guide groove 7d and the second rotation guide groove 11d, and a flange portion 13a of the guide pin 13 is engaged with the guide groove 11f. It is accommodated in the guide recess 12a.

  5 and 8, the reference symbol 14 shown between the rotary base plate 7 and the slide member 11 is a slide biasing means made of, for example, a snake spring, and one end portion 14a thereof is the rotary base plate. 7 is pivotally supported via a pivot pin 15a in a pivot hole 7e provided on one side, and the other end 14b is pivoted to a pivot hole 11g provided on the other side of the slide member 11. It is supported via Thus, the slide urging means 14 is provided in a direction orthogonal to the slide direction in which the slide member 11 slides with respect to the rotation base plate 7, and thus extends when the slide member 11 slides on the rotation base plate 7. The slide member 11 is contracted to urge the slide member 11 to slide forward and backward from a predetermined slide position.

  Similarly, in FIGS. 7 and 9, the reference symbol 16 shown on the lower side of the fixed base plate 8 is a rotation urging means made of, for example, a snake spring. The shape is different. The rotation urging means 16 includes a fixed base plate by a first locking piece 8b, a second locking piece 8c, a third locking piece 8d, and a fourth locking piece 8e provided on the lower surface side of the fixed base plate 8. 8 is fixed in a predetermined posture, and its free end is pressed against one side of the rotation support shaft 9. As a result, the rotating base plate 7 is urged to rotate in either the left or right direction from a predetermined rotation angle. The concave portion 2 c provided on the upper surface of the first housing 2 allows the flange portion 9 b of the rotation support shaft 9 to escape and accommodates the rotation urging means 16.

  Next, the function of the opening / closing device 4 will be described.

First, the relative slide function of the first housing 2 and the second housing 3 will be described. As shown in FIG. 1, when the first casing 2 and the second casing 3 of the mobile phone 1 are overlapped with each other, as shown in FIG. Since the guide pin 13 attached to the fixed base plate 8 is engaged with the rotation restriction guide groove 11e of the guide groove 11f, the guide pin 13 is positioned at the position of the first rotation guide groove 7d provided on the rotation base plate 7. Even so, the rotational motion is restricted.

  When the first housing 2 and the second housing 3 are slid relative to each other in the front-rear direction, the slide member 11 slides with respect to the rotating base plate 7 to expose the upper surface of the first housing 2. In FIG. 4, the operation unit 2a and the display unit 3a are omitted. As shown in FIG. 4 (c), this sliding operation is performed by engaging recess 11h (FIG. 3 and FIG. 3) in which guide pin 13 is provided in second rotation guide groove 11d at the start end of rotation restricting guide groove 11e. 4 (a) and (b) are in contact with each other to stop. In this stopped state, as shown in FIGS. 1B and 4C, the upper surface of the first housing 2 is exposed, and the operation portion 2a can be operated. This is the open state. Returning to the closed state in which the first casing 2 and the second casing 3 overlap from the opened state is relative to the closing direction opposite to the opening direction of the first casing 2 and the second casing 3. This can be done by performing a sliding operation. At the time of this opening / closing operation, as shown in FIGS. 5A to 5C, the slide urging means 14 is compressed and expanded, so that the sliding operation encounters some resistance at the time of opening and closing. The slide urging means 14 exposes the upper surface of the first housing 2 or covers the upper surface during the relative sliding operation of the first housing 2 and the second housing 3. The shaft support pins 15a and 15b are compressed while turning around the fulcrum, and then the compression is changed to the extension operation, and the second housing 3 is slid and biased in the opening direction and the closing direction. At the time of closing and at the time of opening, the slide member 11 is slidably biased in the closing direction and the opening direction with respect to the rotating base plate 7, so that the guide pin 13 is in the rotation restricting guide groove 11 e in the closed state. It also has a lock function that abuts the end portion and locks it by engaging with an engaging recess 11h provided in the central portion of the second rotation guide groove 11d in the opened state. At this time, if the slide urging means 14 is a flat snake spring, there is an advantage that the cellular phone 1 can be thinned by making the opening / closing device 4 thin. However, the slide biasing means 14 is not limited to a flat snake spring, and other known elastic means such as a compression spring, a torsion spring, and a tension coil spring can be used.

  Next, the rotation function of the opening / closing device 4 will be described.

  As shown in FIG. 1B, FIG. 4 and FIG. 5C, the mobile phone 1 is in a state where the second housing 3 is slid to the open position with respect to the first housing 2, As shown in FIGS. 2A to 2C and FIGS. 6A to 7C, respectively, the second housing 3 is in the left or right direction with respect to the first housing 2. Can be rotated horizontally.

  That is, as shown in FIG. 4 and FIG. 5C, the guide pin 13 has the first rotation guide groove 7 d and the second rotation guide at the open position of the second case 3 with respect to the first case 2. It exists in the position which penetrated the groove | channel 11d together. From this state, for example, in order to rotate the second housing 3 relative to the first housing 2, the second housing 3 is moved to the right as shown in FIGS. When the side portion is pushed, the guide pin 13 escapes from the engagement recess 11h and moves in the left portion of the rotation guide portions 7f and 11i of the first rotation guide groove 7d and the second rotation guide groove 11d. Therefore, both the rotation base plate 7 and the slide member 11 rotate rightward with the rotation support shaft 9 as a fulcrum. Similarly, in the leftward rotation, the second housing 3 is rotated leftward with respect to the first housing 2 from the states shown in FIGS. 1B, 4 and 5C. When the side is pushed as much as possible, the guide pin 13 escapes from the engagement recess 11h and moves in the right part of the rotation guide portions 7f and 11i of the first rotation guide groove 7d and the second rotation guide groove 11d. Therefore, both the rotating base plate 7 and the slide member 11 rotate leftward about the rotating support shaft 9 as a fulcrum. The first rotation guide groove 7d and the second rotation guide groove 11d have rotation guide portions 7f and 11i and slide guide portions 7g and 11j, respectively, and are formed symmetrically with respect to the center portion in both the left and right directions. Therefore, the second housing 3 is stopped at a position that is symmetrical with respect to the first housing 2.

  When the second casing 3 is rotated with respect to the first casing 2, the guide pins 13 are guided along the second casing 3 by the first rotating guide groove 7d and the second rotating guide groove 11d. 2 The casing 3 rotates while sliding in the longitudinal direction to the left and right in the rotational direction. In order to allow this sliding operation, the fixed base plate 8 is provided with a guide long hole 8a that allows the rotation support shaft 9 to slide. It has been. That is, when the second housing 3 is rotated in the left-right direction with respect to the first housing 2, in particular, as shown in FIGS. It will slide back and forth in the longitudinal direction. Thus, the rotation locking position of the display unit 3a of the second housing 3, that is, the position where the display unit 3a is locked horizontally with respect to the first housing 2 can be controlled. At this time, the rotation urging means 16 pushes the rotation support shaft 9 at the end thereof, so that the second housing 3 is urged to rotate from a predetermined rotation angle in either the left or right horizontal rotation direction. become. This rotation bias is also performed when the second casing 3 rotated in the left-right direction is returned to the original position, and operates to automatically return to the original position. When the rotation returns to the original position, the guide pin 13 falls into the engaging recess 11h provided in the second rotation guide groove 11d, so that the click is stopped in the state where the guide pin 13 returns to the original position, and the state is stabilized. Will keep it.

  The rotation of the second housing 3 with respect to the first housing 2 in the left-right direction is such that the guide pin 13 is connected to each terminal end of the first rotation guide groove 7d and the second rotation guide groove 11d, that is, each slide guide portion. 7g and 11j are stopped by coming into contact with the end portions, and locked at that position by the urging force of the rotation urging means 16 pushing the guide pin 13. The rotation urging means 16 is a flat snake spring in the drawing, but it can be replaced with a compression spring, a torsion coil spring, or a tension spring. Moreover, the feeling at the time of relative rotation operation of the 2nd housing | casing 3 and the 1st housing | casing 2 can also be changed by changing the shape of the 1st rotation guide groove 7d and the 2nd rotation guide groove 11d. become.

  In the above embodiment, the fixed base plate 8 and the fixing member 12 can be omitted by providing the first casing 2 and the second casing 3 in place of them. Further, the casing for mounting the rotating base plate 7, the fixed base plate 8, the slide member 11 and the fixing member 12 is opposite to that shown in the drawing, that is, the rotating base plate 7 and the fixed base plate 8 are provided on the lower surface side of the second casing 3 to slide. It is possible to provide the member 11 and the fixing member 12 on the upper surface side of the first housing 2. In that case, in the claims, the first housing is read as the second housing, and the second housing is read as the first housing.

  As described above in detail, the switchgear according to the present invention includes a first casing having an operation unit on the top surface of a portable device and a second casing having a display unit on the top surface. An open / close operation that slides back and forth from the formed state to expose the upper surface of the first housing, and in this opened state, the second housing is evenly rotated horizontally and horizontally with respect to the first housing. It is suitable as an opening / closing device capable of performing both operations of rotating operation, and is suitably used as a portable device using this opening / closing device.
