Show.

  A pair of sliding portions 12 are provided on the left and right ends on the upper surface of the second casing 3 so as to extend in the vertical direction. As shown also in FIG. 15, the pair of sliding portions 12 is formed in a groove shape provided so as to be recessed outward from the left and right center side of the second housing 3. On the other hand, on the back cabinet 2a on the back side of the first housing 2, a rail portion 13 that is inserted in the pair of sliding portions 12 and that is long in the vertical direction is formed so as to protrude in the left-right direction. The sliding portion 12 is shorter than the rail portion 13 in the vertical direction, and the sliding portion 12 is arranged so that the rail portion 13 is sandwiched from the left and right sides, so that the sliding portion 12 becomes the rail portion 13. The first casing 2 slides on the second casing 3 in a stable manner by sliding up and down.

  A torsion coil spring 20 as a first elastic member is provided between the pair of sliding portions 12. The torsion coil spring 20 assists the sliding movement of the first casing 2 toward the upper end side of the second casing 3, and assists the sliding movement to the original position (downward) after the sliding. It has become. The torsion coil spring 20 is disposed so that the torsion angle of the torsion coil spring 20 is minimized and the most force can be stored at an intermediate position of the entire slide path of the first housing 2. 6 to 9, the second housing 3 shows only the sliding portion 12, the other portions are shown by a two-dot chain line, and the torsion coil spring 20 is drawn by a solid line for the sake of clarity.

  As shown in FIG. 10, the torsion coil spring 20 is made of a stainless steel wire for spring (for example, SUS304WPA or SUS304WPB). For this reason, it is excellent in corrosion resistance and has improved durability. The torsion coil spring 20 includes first and second coil portions 21 and 22 and first to third straight portions 23, 24, and 25. One end of the first coil portion 21 is continuous with the first straight portion 23, and the other end is continuous with the second straight portion 24. The other end of the second linear portion 24 is continuous with the second coil portion 22, and the other end of the second coil portion 22 is continuous with the third linear portion 25. In the present embodiment, the first straight part 23 is longer than the third straight part 25.

  The first and second coil portions 21 and 22 have the maximum diameter portions 21a and 22a and the second straight portion 24 arranged in the same plane. The minimum diameter portions 21 b and 22 b and the maximum diameter portions 21 a and 22 a of the first and second coil portions 21 and 22 are disposed in the same plane as the second linear portion 24 and are the outermost portions of the first coil portion 21. From the small diameter portion 21b to the first straight portion 23, and from the smallest diameter portion 22b of the second coil portion 22 to the third straight portion 25, the projections are continuous in the same direction (surface side) away from the same plane. Thus, since the part which continues from the 1st and 2nd coil parts 21 and 22 to the 1st or 3rd straight parts 23 and 25 protrudes from the 1st and 2nd coil parts 21 and 22 in the same direction, The overall height is reduced, allowing placement in tight spaces.

  A first annular portion 26 is formed at the tip of the first straight portion 23, and a second annular portion 27 is formed at the tip of the third straight portion 25. A first spring fixing pin 29 is provided in the vicinity of the side surface of the first housing 2 as viewed from the front surface, that is, on the left side in the vertical center portion on the back surface side of the back cabinet 2a so as to protrude toward the second housing 3 side. It has been. Similarly, the second spring fixing pin 30 protrudes toward the first housing 2 in the vicinity of the opposite side surface of the second housing 3 when viewed from the surface, that is, on the upper side and the right side of the top surface in the vertical direction. It is provided to do. The first annular portion 26 is rotatably positioned on the first spring fixing pin 29. Similarly, the second annular portion 27 is rotatably positioned on the second spring fixing pin 30.

  The torsion coil spring 20 changes its torsion angle when a force is applied to the first and third linear portions 23 and 25, and the first and second coil portions 21 and 22 generate a stretching force in the torsion direction. By providing the two coil parts 21 and 22, the torsion angle of each coil part can be halved as compared with the one having only one coil part. For this reason, in order to generate an equivalent torsion angle, the sizes of the coil portions 21 and 22 are smaller than in the case of one coil portion.

  As a feature of the present invention, a pair of leaf springs 35 as second elastic members are provided on the right side surface of the first housing 2 with a space in the vertical direction. As shown in FIG. 16, the leaf spring 35 is formed with a slit 35a in the middle so as to have a spring property, and is divided into two at the left and right middle, and two through holes 35c are formed on the flat mounting portion 35b side. And one end side of the attachment portion 35b is connected to the movable portion 35d. The movable portion 35d is slightly bent so that the tip end side is inclined downward. The leaf spring 35 is made of phosphor bronze. Phosphor bronze has many characteristics as a non-ferrous metal material that has excellent spring properties, high strength, good bending and drawing workability, good wear resistance, and resistance to chemical corrosion. Therefore, the leaf spring 35 having an appropriate price level that is easy to use can be obtained. The leaf spring 35 may be made of stainless steel. As a result, a highly durable leaf spring 35 which is not easily rusted is obtained.

  As shown in FIG. 15, mounting holes 13 a are formed in the vicinity of the rail portion 13 (on the left and right sides) in the first housing 2 so as to correspond to the through holes 35 c. The leaf spring 35 is joined to the first housing 2 by the rivet 36 by inserting the rivet 36 into the mounting hole 13 a and the through hole 35 c and crushing the tip. As shown in FIG. 10B, the leaf spring 35 is moved along with the sliding movement, and the sliding portion 12 enters the movable portion 35d of the leaf spring 35 and is pressed. Thus, the impact generated at the time of completion of the slide movement when sliding from the open state to the closed state and when sliding from the closed state to the open state is alleviated.

  The slide mechanism 4 includes a pair of sliding portions 12, a pair of rail portions 13, a torsion coil spring 20, and a leaf spring 35.

-Action-
Next, the sliding operation of the sliding mobile phone 1 according to the present embodiment will be described with reference to the drawings.

  FIGS. 11 to 14 show the positional relationship between the sliding portion 12 and the leaf spring 35 when the sliding mobile phone slides from the closed state to the open state. 17 to 20 show the positional relationship between the sliding portion 12 and the leaf spring 35 when the sliding mobile phone slides from the closed state to the open state.

  First, as shown in FIGS. 2, 6, 11, and 17, in the standby state (closed state), the first housing 2 is overlapped with the second housing 3. The shape of the torsion coil spring 20 is such that the two coil portions 21 and 22 are arranged at substantially the same height on the left and right in a plan view. Since the sliding part 12 enters below the movable part 35d and pushes it with the strongest force so as to push up the entire movable part 35d of the upper leaf spring 35, the first casing 2 does not wobble.

  Next, as shown in FIGS. 3, 7, 12, and 18, the first housing 2 is slightly slid upward. At this time, the first housing 2 moves upward along the sliding portion 12 provided in the second housing 3. The second annular portion 27 is in a fixed position, and rotates around the second spring fixing pin 30, and the first annular portion 26 moves upward while rotating around the first spring fixing pin 29. The shape of the torsion coil spring 20 is such that the first coil portion 21 is positioned above the second coil portion 22 and has a mountain shape as a whole. Since the torsion angle of the torsion coil spring 20 is smaller than that of the free shape, the first casing 2 is slid against the biasing force. The movable part 35d of the upper leaf spring 35 moves relative to the sliding part 12, and the sliding part 12 is in a state where the movable part 35d is slightly lifted. For this reason, the urging force of the leaf spring 35 is weak.

  Next, although illustration is omitted, when the first casing 2 is further moved upward, the operation unit 7 gradually appears and reaches an intermediate position of the sliding movement of the first casing 2. The shape of the torsion coil spring 20 is such that the first coil portion 21 moves further upward and to the right. At this time, the torsion angle of the torsion coil spring 20 becomes the smallest, and the elastic energy is stored most. Since the leaf spring 35 is completely detached from the sliding portion 12, the urging force of the leaf spring 35 is not applied at all.

  Next, as shown in FIGS. 4, 8, 13, and 19, when the first housing 2 exceeds the intermediate position, the torsion coil spring 20 that has been compressed tries to return to the original position. The body 2 is urged downward and automatically slides. At this time, the sliding portion 12 enters the intermediate position of the movable portion 35d of the lower leaf spring 35, and lifts the movable portion 35d slightly. For this reason, the speed of the 1st housing | casing 2 which is slidingly moved swiftly by the torsion coil spring 20 is weakened.

  Next, the first casing 2 further moves upward, and the first casing 2 moves to the upper end side of the second casing 3 as shown in FIGS. 5, 9, 14, and 20. Then, the operation unit 7 appears completely, the operation unit 7 can be operated, and a telephone call can be performed. The shape of the torsion coil spring 20 is such that the first coil portion 21 moves to the upper side of the second coil portion 22 and the first and second coil portions 21 and 22 are positioned at the right end. At this time, the sliding portion 12 enters the state where the movable portion 35d of the leaf spring 35 is completely pushed up and is pressed with the strongest force. For this reason, the first housing 2 is stopped while the impact is alleviated and does not wobble in the open state.

  In this way, the spring works strongly in the closed state and weakens as the open state is reached, and the spring becomes strong again when the opening is completed. The first housing 2 does not wobble in the closed state.

  Conversely, when the first casing 2 is overlapped with the second casing 3, the operation is the reverse of the above.

  Thus, when the first casing 2 is slightly slid by hand and released by the urging force of the torsion coil spring 20, it tries to return to the state before the slide, but it slides a lot by hand and passes the intermediate position. When the is released, the first housing 2 slides. That is, since the torsion coil spring 20 assists the sliding movement of the first housing 2 in any direction, the sliding operation is smoothly performed with one touch.

  In either case of sliding from the open state to the closed state or sliding from the closed state to the open state, the sliding movement is assisted by the torsion coil spring 20, but the biasing force of the torsion coil spring 20 is applied. Even if it is increased, the impact generated at the time of completion of the slide movement is alleviated by the leaf spring 35 in any case. Thus, the shock at the time of a slide operation is reduced with a simple configuration in which only the leaf spring 35 is provided.

  By providing the leaf spring 35 in the first casing 2, the relaxation action of the leaf spring 35 is surely given when the sliding movement is completed in accordance with the sliding movement of the second casing 3.

  By providing the leaf springs 35 at an interval, the impact generated when the slide movement is completed when sliding from the open state to the closed state and when sliding from the closed state to the open state is alleviated. Further, by providing the leaf springs 35 together on the right side surface, the space on the left side surface is effectively used.

  When the first housing 2 is slid, the sliding portion 12 is pressed against the movable portion 35d of the leaf spring 35 on the rail portion 13, so that the impact generated when the sliding movement is completed is reduced.

-Effect of the embodiment-
Therefore, according to the slide type mobile phone 1 according to the present embodiment, the torsion coil spring 20 that assists the sliding movement of the first housing 2 and the leaf spring 35 for alleviating the impact that occurs when the sliding movement is completed. Thus, a suitable urging force can be applied with a simple structure, and a comfortable sliding movement can be performed without feeling an impact when the sliding movement is completed, and a compact sliding mobile phone 1 can be obtained.

  Further, since the second elastic member is configured by the leaf spring 35, the impact generated at the time of completion of the slide movement can be reduced with a simple and thin structure, so that the slide type mobile phone 1 having a compact and good operability is obtained. It is done.

  Further, at the middle position of the entire sliding position of the first housing 2, the torsional angle of the torsion coil spring 20 is minimized so as to store the most force, and the sliding movement of the first housing 2 is assisted in any direction. I am doing so. For this reason, the slide operation of the first housing 2 can be performed in one direction with one touch.

(Other embodiments)
The present invention may be configured as follows with respect to the above embodiment.

  In other words, in the above-described embodiment, the leaf spring 35 is provided only on the right side surface of the first housing 2 with a space in the vertical direction, but may be provided only on the left side surface. Moreover, you may provide one each on both the left and right side surfaces at intervals up and down. By arranging in this way on the left and right, the force is evenly applied and the balance is improved.

  Alternatively, the sliding portion 12 may be provided on the first housing 2 side, and the sliding portion 12 may be slid along the rail portion 13 provided on the second housing 3. In this case, a leaf spring 35 may be provided on the second housing 3 side, and the sliding portion 12 may be pressed by the movable portion 35d.

  Further, the torsion coil spring 20 is provided so as to assist only in the sliding movement from the closed state to the open state, and an impact generated at the time of completion of the sliding movement is provided by the leaf spring 35 provided only on the upper side of the first housing 2. You may make it relax. In this case, although the sliding movement is assisted by the torsion coil spring 20, even if the urging force of the torsion coil spring 20 is increased, the impact generated at the time of completion of the sliding movement is alleviated by the leaf spring 35. Conversely, the torsion coil spring 20 is provided so as to assist only in the sliding movement from the open state to the closed state, and is generated when the sliding movement is completed by the leaf spring 35 provided only on the lower side of the first housing 2. You may make it ease the impact to do. In this case, when the sliding movement from the open state to the closed state is performed, the sliding movement is assisted by the torsion coil spring 20, but even if the biasing force of the torsion coil spring 20 is increased, the leaf spring 35 causes the sliding movement to be completed. The generated impact is alleviated. As described above, in any case, the shock at the time of the slide operation is reduced with a simple configuration in which only the leaf spring 35 is provided.

  Although not shown, a second operation unit may be provided below the surface of the first housing 2. Thus, the second operation unit can be operated in a state in which the first casing 2 and the second casing 3 are overlapped, and the display unit 5 is set in the horizontally long state to operate the second operation unit.
