Description

  The present invention relates to a curve slide mechanism for a portable terminal.

  Among mobile phones that represent mobile terminals, there is a slide type in which a transmitter and a receiver are incorporated in separate housings, and the two housings are overlapped on the front and back to reduce the size. Therefore, the slide type is strongly required to be thin.

  The slide type has an LCD as a display unit on the front of the front case, a receiver as a receiver on the upper part of the LCD, and a numeric keypad, a call button, and a switch as an operation unit at the lower front of the rear case. Buttons, function buttons, etc. are provided, a microphone as a transmitter is provided at the bottom of the operation unit, and the front and rear housings are slidably connected in the vertical direction to provide an extendable transmitter / receiver unit. Constitute.

  In the slide type, the two housings are bent in an arc along the vertical direction (longitudinal direction) so that the rear surface of the front housing is convex, and the front surface of the rear housing is the front housing. It bends along an arc along the rear surface, and has a concave surface with substantially the same curvature. The front housing and the rear housing are curved and slides between the front and rear housings. It is connected so that a curve slide is possible so that an arc may be drawn along the front of.

  When carrying without using a mobile phone, the entire rear surface of the front housing and the entire front surface of the rear housing are overlapped to form a compact closed state. When in use, the front casing is slid upward to open, and the transmitter and the operating unit appear. In the open state, the mobile phone body has a curved shape and follows the contour of the side of the face from one ear to the mouth.

  A rail plate made of a metal plate is fixed to the rear surface of the front case, and a guide plate made of a metal plate is fixed to the upper part of the front surface of the rear case. Curved rails that curve along the rear surface of the body with substantially the same curvature and extend in parallel with the vertical direction are provided, and the guide rails can be slid by embedding the curved rails from the outside on the left and right sides of the guide plate. A sliding guide made of synthetic resin to be fitted is provided, and in order to assist the curve slide of the front housing from the closed position to the open position, and to assist the curve slide from the open position to the closed position, Between the rail plate and the guide plate, an urging member for urging the front casing upward or urging downward is provided to constitute a curve slide mechanism.

  In the slide-type slide operation, when the front casing is manually pushed upward to some extent from the closed state, the front casing is curved and slid to the open position by the biasing force of the biasing member. When the front housing is manually pulled downward from the open state to some extent, the front housing is curved and slid to the closed position by the urging force of the urging member.

  As such a curve slide mechanism, there exists a thing described in patent document 1, for example.

International Publication No. 2008/018735

  Patent Document 1 discloses a spring in which a wire is bent in a waveform on one plane as an urging member of a curve slide mechanism, but in general, a torsion coil spring is used.

  In the torsion coil spring, a pair of leg portions are drawn out from the coil portion, a loop-like portion as a plate connecting portion is provided at the tip portion of each leg portion, and one loop-like portion is caulked and fixed to the rail plate by a rivet, The other loop-shaped part is fixed to the guide plate by rivets and is provided between the rail plate and the guide plate.

  In the curve slide mechanism, the distance between the urging member connecting portion of the rail plate and the urging member connecting portion of the guide plate (distance in the thickness direction of the curve slide mechanism) varies with the curve slide, but the torsion coil spring The bending due to such fluctuation is absorbed by the bending of the leg portion, and the urging function can be exhibited without any problem.

  However, when the torsion coil spring is used, the rail plate and the guide plate need to have at least a distance corresponding to the thickness of two wire diameters (coil portions) of the torsion coil spring, and the torsion coil spring is used. In order to prevent scraping due to metal contact (sliding contact) between each loop-shaped part and the rivet head and between each loop-shaped part and the rail plate or guide plate, a ring-shaped synthetic resin sheet between them However, the necessary distance between the rail plate and the guide plate is further increased.

  Such an interval between the rail plate and the guide plate cannot be reduced as long as the torsion coil spring is used, and the torsion coil spring prevents the curve slide mechanism from being thinned (that is, the slide type mobile phone is thinned).

  An object of the present invention is to provide a curved slide mechanism for a portable terminal (that is, a slide type portable terminal) thinner than the conventional one by using a specific urging mechanism as the urging member.

  The invention according to claims 1 and 2 is a curved slide mechanism for a portable terminal that is connected so as to be slidable while drawing an arc in the vertical direction in a state where the two casings of the slide-type portable terminal are overlapped in the front-rear direction. Curved along an up-down direction so that the rear surface of the front housing is convex, curved, curved so that the front surface of the rear housing is along the rear surface, and a concave surface with substantially the same curvature A rail plate made of a metal plate is fixed to the rear surface, and a guide plate made of a metal plate is fixed to the upper part of the front surface, and substantially the same so that the left and right sides of the rail plate are along the rear surface. It is made of a synthetic resin that is bent so as to draw an arc with a curvature, and is provided with curved rails extending in parallel in the vertical direction, and the curved rails are slidably fitted to both the left and right sides of the guide plate. The slide-type portable device in which a ride guide is provided and an operation unit in which the front case is provided at a lower portion of the front surface appears from a closed state of the slide-type portable terminal in which the entire rear surface and the entire front surface are overlapped In order to assist the curve sliding upward to the open position of the terminal open state, and to assist the curve sliding downward from the open state to the closed position of the closed state, In the curved slide mechanism for a portable terminal configured to be provided with an urging member that urges the front casing upward and urges downward between the rail plate and the guide plate. A biasing mechanism that linearly expands and contracts on one plane as a biasing member, and a fixing pin as a biasing mechanism connecting portion of the rail plate and the guide plate, The biasing mechanism includes parallel first and second compression coil springs, a single plate-like chassis made of synthetic resin that supports one end of the first and second compression coil springs from the opposite side, and the plate-like chassis. And the first and second plate-like movable elements made of synthetic resin, which are separately attached so as to be capable of linear reciprocation and separately support the other ends of the first and second compression coil springs from opposite sides. A plate-like locking portion that is integrally formed with the first and second plate-like movable elements on the one plane and that can be fitted to the fixing pin from the side, and a plate-like locking portion; A head portion formed integrally with the distal end portion of the fixing pin is provided as a retaining portion of the locking portion from the fixing pin.

  In the invention according to claim 1, the pressing surface of the head is formed into a spherical convex surface, and the pressed surface of the plate-like locking portion has a spherical concave surface with substantially the same curvature so as to follow the pressing surface. The pressing surface and the pressed surface are overlapped in a spherical shape and slide to absorb the deflection of the urging mechanism accompanying the curve slide that draws the arc of the rail plate.

  In the invention according to claim 2, the first and second plate-like movable elements are provided with weakening portions for allowing the plate-like locking portions to bend, and the first and second plate-like movable members are provided. When the mover bends with respect to the plate-like locking portion, the bending of the biasing mechanism accompanying the curve slide that draws the arc of the rail plate is absorbed.

  According to the first and second aspects of the invention having such a configuration, the urging member of the curved slide mechanism for the portable terminal has a planar structure and is very thin and linearly expands and contracts on one plane. An urging mechanism can be used (for example, a thickness approximately equal to the wire diameter of a torsion coil spring), and a thinner mobile terminal slide slide mechanism (that is, a slide type mobile terminal) can be provided.

  The structure of the urging mechanism is not complicated in order to absorb the deflection of the urging mechanism that accompanies the curved slide that draws the arc of the rail plate, so that the thinness of the urging mechanism is not impaired, and the urging mechanism A curve slide mechanism for a mobile terminal (that is, a slide type mobile terminal) can be effectively reduced in thickness.

  Since the urging mechanism can be attached after the fixing pins are attached to the rail plate and the guide plate, the curve slide mechanism for the portable terminal can be easily assembled and the manufacturing cost can be reduced.

  In the urging mechanism, the first and second plate-like movers that provide the plate-like locking part as the plate connecting part are made of synthetic resin, so there is no need for a synthetic resin sheet to prevent scraping due to contact between metals Thus, the curve slide mechanism for mobile terminals (that is, the slide type mobile terminal) can be further thinned, the curve slide mechanism for mobile terminals can be further easily assembled, and the manufacturing cost can be further reduced.

A slide stopper (not shown) is provided in the upward direction of the movable armature 25, and these two slide stoppers become stoppers on the extension side of the urging mechanism 14.

  A straight core rod (not shown) made of wire is provided inside the first and second compression coil springs 21 and 22 to prevent the first and second compression coil springs 21 and 22 from being bent. One end of each core rod is fixed to the movable spring receivers 24c and 25c, and the other end slides the first and second plate-shaped movable elements 24 and 25 with respect to the fixed spring receivers 23a and 23b (the biasing mechanism 14). The fixed spring receivers 23a and 23b and the movable spring receivers 24c and 25c are inserted and supported so as to be able to be inserted and removed in accordance with fluctuations in the relative distance between them.

The arcuate surface is in a cylindrical surface with the axis in the direction orthogonal to the sliding direction of the first and second plate-like movable elements 24 and 25 as the center.

  In this way, the biasing mechanism 14 having a planar structure and a thickness that is substantially the same as the wire diameter of a torsion coil spring used as a conventional biasing member, for example, about 1 mm, is formed.

  In FIG. 10, the operation of the urging mechanism 14 alone will be described.

  The first plate-like movable element 24 is not subjected to an external force (load) that pushes it upward against the urging force of the first compression coil spring 21, and the second plate-like movable element 25 has When there is no external force (load) that pushes this downward against the urging force of the second compression coil spring 22, that is, the first and second plate-like movable elements 24, 25 are subjected to the first force. When no external force (load) is applied in the direction in which the biasing mechanism 14 contracts against the biasing force of the first and second compression coil springs 21 and 22, the lower plate-like rail 23c and the slider The first plate-like movable element 24 is held at the downward slide end position (solid line position in FIG. 10) by the biasing force of the slide stopper (not shown) provided between the portions 24b and the first compression coil spring 21.

Finally, the first plate-like movable element 24 slides upward against the stopper 23e from below. Slide to the end position (imaginary line position in Fig. 10), and the slide is regulated Then, the second plate-shaped movable element 25 slides to the slide end position (the imaginary line position in FIG. 10) in the downward direction where it abuts against the stopper 23e from above, and the slide is restricted, that is, the first and second At the slide end position in the direction in which the plate-like terminals 24, 25 approach each other, the slide is restricted, and the urging mechanism 14 is in the most contracted state (the length approximately equal to the length of the plate-like chassis 23). Become.

  When the external force applied to the first and second plate-like movable elements 24 and 25 is released, the urging mechanism 14 returns to the original free state.

  Thus, the urging mechanism 14 linearly expands and contracts within one plane.

  As shown in FIG. 12, rivets having the same structure are used for the fixing pins 20 a and 20 b, and have a stepped shaft portion 28 and a head portion 29 provided at the large-diameter side end portion of the shaft portion 28.

  As shown in FIGS. 5 to 8, a fixing pin 20 a is fixed to the rail plate 9 at one location that is substantially intermediate between the upper and lower sides and is shifted to the left and right sides (right side in the present embodiment). The fixing pin 20b is fixed at one position which is biased to the left and right sides (the left side in the present embodiment) opposite to the fixing pin 20a of the rail plate 9 in the middle between the upper and lower sides.

  As shown in FIG. 13, in order to fix the fixing pin 20a to the rail plate 9, the small diameter of the shaft portion 28 of the fixing pin 20a (the rivet as the fixing pin 20a) is fixed to the fixing pin 20a fixing portion of the rail plate 9 in advance. A pilot hole 30 having substantially the same diameter as the part diameter is opened, and a small diameter part of the shaft part 28 is inserted into the lower hole 30 from the inner surface side of the rail plate 9, and the small diameter of the shaft part 28 protruding to the outer surface side of the rail plate 9 is inserted. The tip part of the part is crushed to form a flat head part 31, and the shaft part 28 is caulked and fixed to the rail plate 9 around the lower hole 30 by the step of the shaft part 28 and the flat head part 31. In the fixing pin 20 a fixed to the rail plate 9 in this manner, the shaft portion 28 projects vertically from the inner surface of the rail plate 9, and the head portion 29 is provided at the projecting end of the shaft portion 28.

  In order to prevent the flat head 31 of the fixing pin 20a from protruding on the outer surface of the rail plate 9 and impairing the thinness of the urging mechanism 14, the fixing pin 20a fixing portion of the rail plate 9 has a convex inner surface and the outer surface is fixed. An overhanging portion 32 that is concave is formed, a lower hole 30 is formed in the center of the overhanging portion 32, the fixing pin 20 a is caulked and fixed to the rail plate 9, and the flat head 31 of the fixing pin 20 a is attached to the outer surface of the overhanging portion 32. It is embedded in the recess.

  The fixing pin 20b is fixed to the guide plate 10 in the same manner as the fixing pin 20a is fixed to the rail plate 9. That is, a pilot hole 30 having a diameter substantially the same as the diameter of the small diameter portion of the shaft portion 28 of the fixing pin 20b (a rivet as the fixing pin 20b) is formed in advance at the fixing pin 20b fixing position of the guide plate 10. The small diameter portion of the shaft portion 28 is inserted into the guide plate 10 from the inner surface side, the tip portion of the small diameter portion of the shaft portion 28 protruding to the outer surface side of the guide plate 10 is crushed, and a flat head 30 is formed there. The shaft portion 28 is caulked and fixed to the guide plate 10 around the lower hole 30 by the step of the shaft portion 28 and the flat head portion 31. In the fixing pin 20 b fixed to the guide plate 10 in this manner, the shaft portion 28 protrudes vertically from the inner surface of the guide plate 10, and has a head portion 29 at the protruding end of the shaft portion 28.

  Similarly to the fixing pin 20a of the rail plate 9, the flat head 31 of the fixing pin 20b protrudes from the outer surface of the guide plate 10 to prevent the biasing mechanism 14 from being damaged, so that the fixing pin 20b of the guide plate 10 is fixed. A protruding portion 32 having a convex inner surface and a concave outer surface is formed at the location, a lower hole 30 is formed in the central portion of the protruding portion 32, and the fixing pin 20b is caulked and fixed to the guide plate 10. The flat head portion 31 is embedded in the concave portion on the outer surface of the overhang portion 32.

  13 and 14, the urging mechanism 14 fixes the fixed pin 20a to the rail plate 9, fixes the fixed pin 20b to the guide plate 10, and then the shaft of the fixed pin 20a of the rail plate 9. For example, a plate-like engaging portion 26 a integrally formed with the first plate-like movable element 24 is fitted from the side as a plate connecting portion at one end of the urging mechanism 14 to the portion 28, and the guide plate 10. A plate-like locking portion 26b formed integrally with the second plate-like movable element 25 as a plate connecting portion at the other end of the urging mechanism 14 is externally fitted to the shaft portion 28 of the fixing pin 20b from the side. As a result, as shown in FIGS. 5 to 8, the fixing pin 20 a of the rail plate 9 and the guide plate 10 are obliquely installed between the fixing pins 20 b.

  At this time, the urging mechanism 14 is closed by the urging force of the first and second compression coil springs 21, 22 on the outer peripheral surface of the shaft portion 28 of the fixed pin 20 a of the rail plate 9. The shaft portion 28 of the fixing pin 20a of the rail plate 9 is fitted into the innermost part of the U-shaped groove 26a 'of the plate-like engaging portion 26a, and the head of the fixing pin 20a of the rail plate 9 is locked. The closed end portion of the plate-like locking portion 26a is sandwiched between the portion 29 and the rail plate 9, and the head 29 of the fixing pin 20a of the rail plate 9 is moved from the fixing pin 20a of the rail plate 9 of the plate-like locking portion 26a. The protrusion 27a of the plate-like locking part 26a contacts the rail plate 9 to fill the gap between the plate-like locking part 26a and the rail plate 9 and prevent the biasing mechanism 14 from rattling. Demonstrate the function.

  Further, the closed end portion of the plate-like locking portion 26b is pressed against and locked to the outer peripheral surface of the shaft portion 28 of the fixing pin 20b of the guide plate 10, and the innermost portion of the U-shaped groove 26b ′ of the plate-like locking portion 26b is locked. The shaft portion 28 of the fixing pin 20b of the guide plate 10 is fitted into the guide plate 10, and the closed end portion of the plate-like locking portion 26b is sandwiched between the head 29 of the fixing pin 20b of the guide plate 10 and the guide plate 10, and the guide plate The head 29 of the ten fixing pins 20b functions to prevent the plate-like locking portion 26b from coming off from the fixing pins 20b of the guide plate 10, and the projection 27b of the plate-like locking portion 26b contacts the guide plate 10. Thus, the gap between the plate-like locking part 26b and the guide plate 10 is filled, and the play preventing function of the urging mechanism 14 is exhibited.

  The operation of the curve slide mechanism 8 will be described with reference to FIGS.

  As shown in FIG. 5, in the closed state of the slide type mobile phone 1, the rail plate 9 is fitted with the slide guide 13 of the guide plate 10 at the upper part of the curve rail 11, and the rail plate 9 is downward (closed direction). It is located at the end position (closed position) of the curve slide in the downward direction where the curve slide stopper (not shown) works, and the fixed pin 20a of the rail plate 9 is positioned below the fixed pin 20b of the guide plate 10, The biasing force of the first and second compression coil springs 21 and 22 of the biasing mechanism 14 is biased downward via the fixing pin 20a of the rail plate 9, and the rail plate 9 is not illustrated downward. Due to the urging force of the first and second compression coil springs 21 and 22 of the curve slide stopper and the urging mechanism 14, the curve slide end position (closed position) is lowered. Position is held in). Therefore, the curve slide mechanism 8 holds the front housing 2 in the closed position shown in FIG. 1A, and holds the closed state of the slide type mobile phone 1.

  When the slide type mobile phone 1 is used, when the front housing 2 is manually pushed upward from the closed state shown in FIG. 1A, the curve slide mechanism 8 moves the rail against the slide guide 13 of the guide plate 10. While the curved rail 11 of the plate 9 slides upward (opening direction), the rail plate 9 curves upwardly with respect to the guide plate 10, and the front housing 2 is moved to the front of the rear housing 3. Slide the curve along 3a.

  At this time, the inter-axis distance between the fixing pin 20b of the guide plate 10 and the fixing pin 20a of the rail plate 9 is equal to the upper distance of the fixing pin 20a of the rail plate 9 as the rail plate 9 is slid upward with respect to the guide plate 10. Due to the movement in the direction, the fixing pins 20a of the rail plate 9 are gradually shortened with respect to the fixing pins 20b of the guide plate 10 to the position shown in FIG. The fixing pin 20a of the plate 9 is the shortest at the position shown in FIG. 7 aligned in a horizontal row, and after the fixing pin 20a of the rail plate 9 exceeds the fixing pin 20b of the guide plate 10, it becomes gradually longer.

  The biasing mechanism 14 supports the shaft portion 28 of the fixed pin 20b of the guide plate 10 by moving the fixed pin 20a of the rail plate 9 upward along with the upward curve slide of the rail plate 9 with respect to the guide plate 10. The first and second compression coil springs 21 and 22 are rotated up to the position shown in FIG. 7 where the fixing pins 20a of the rail plate 9 are arranged in a horizontal row with respect to the fixing pins 20b of the guide plate 10 while rotating counterclockwise. 7 is gradually contracted against the urging force of the guide plate 10, and the fixing pin 20a of the rail plate 9 is contracted most with respect to the fixing pin 20b of the guide plate 10 at the position shown in FIG. After the shaft exceeds the fixed pin 20b of the guide plate 10, it gradually expands by the urging force of the first and second compression coil springs 21 and 22.

  That is, the urging mechanism 14 moves the shaft portion 28 of the fixing pin 20b of the guide plate 10 by moving the fixing pin 20a of the rail plate 9 upward along with the upward curve slide of the rail plate 9 with respect to the guide plate 10. The first and second compression coil springs 21 are rotated up to the position shown in FIG. 7 in which the fixing pins 20a of the rail plate 9 are arranged in a horizontal row with respect to the fixing pins 20b of the guide plate 10 while rotating counterclockwise around the fulcrum. , 22 urges the rail plate 9 downward via the fixing pin 20a of the rail plate 9, but the fixing pin 20a of the rail plate 9 is in a horizontal row with respect to the fixing pin 20b of the guide plate 10. After exceeding the position shown in FIG. 7 (after exceeding the fulcrum), by the urging force of the first and second compression coil springs 21 and 22 Via the fixing pin 20a of the rail plate 9 for biasing the rail plate 9 upward.

  Therefore, the curve slide mechanism 8 is shown in FIG. 7 in which the fixing pin 20a of the rail plate 9 is arranged in a horizontal line with respect to the fixing pin 20b of the guide plate 10 from the closed state shown in FIG. When it is manually pushed upward until it exceeds the position shown, the rails are then moved via the fixing pins 20a of the rail plate 9 by the biasing forces of the first and second compression coil springs 21 and 22 of the biasing mechanism 14. The plate 9 is urged upward, the rail plate 9 is curvedly slid upward with respect to the guide plate 10, and the front casing 2 is slid along the front surface 3a of the rear casing 3. . As shown in FIG. 6, the rail plate 9 is configured such that the lower part of the curve rail 11 of the rail plate 9 is fitted to the slide guide 13 of the guide plate 10, and a curve slide stopper (not shown) in the upward direction of the rail plate 9 is provided. Curved slide stoppers (not shown) and the first and second compression coil springs 21 of the urging mechanism 14 that are not shown in the figure are slid upwardly to the working curve slide end position (open position). , 22 is held at the curve slide end position (open position) in the upward direction. Therefore, the curve slide mechanism 8 holds the front housing 2 in the open position shown in FIG. 1B and holds the open state of the slide type mobile phone 1.

  When the slide-type mobile phone 1 is carried, when the front housing 2 is manually pulled downward from the open state shown in FIG. 1B, the curve slide mechanism 8 moves the rail against the slide guide 13 of the guide plate 10. While the curved rail 11 of the plate 9 slides downward, the rail plate 9 slides downward with respect to the guide plate 10, and moves the front housing 2 along the front surface 3 a of the rear housing 3. Slide the curve.

  At this time, the inter-axis distance between the fixed pin 20b of the guide plate 10 and the fixed pin 20a of the rail plate 9 is below the fixed pin 20a of the rail plate 9 due to the downward curve slide of the rail plate 9 with respect to the guide plate 10. Due to the movement in the direction, the fixing pins 20a of the rail plate 9 are gradually shortened with respect to the fixing pins 20b of the guide plate 10 to the position shown in FIG. The fixing pin 20a of the plate 9 is the shortest at the position shown in FIG. 7 aligned in a horizontal row, and after the fixing pin 20a of the rail plate 9 exceeds the fixing pin 20b of the guide plate 10, it becomes gradually longer.

  The urging mechanism 14 supports the shaft portion 28 of the fixing pin 20b of the guide plate 10 by the downward movement of the fixing pin 20a of the rail plate 9 in accordance with the downward curve slide of the rail plate 9 with respect to the guide plate 10. The first and second compression coil springs 21 and 22 are rotated until the position shown in FIG. 7 in which the fixing pins 20a of the rail plate 9 are arranged in a horizontal row with respect to the fixing pins 20b of the guide plate 10 while rotating clockwise. 7 gradually contracts against the urging force, and the fixing pin 20a of the rail plate 9 contracts most with respect to the fixing pin 20b of the guide plate 10 at the position shown in FIG. After exceeding the fixing pin 20 b of the guide plate 10, the guide plate 10 is gradually expanded by the urging force of the first and second compression coil springs 21 and 22.

  That is, the urging mechanism 14 moves the shaft portion 28 of the fixing pin 20b of the guide plate 10 by moving the fixing pin 20a of the rail plate 9 downward along with the downward slide of the rail plate 9 with respect to the guide plate 10. The first and second compression coil springs 21, until the position shown in FIG. 7 in which the fixing pins 20a of the rail plate 9 are arranged in a horizontal row with respect to the fixing pins 20b of the guide plate 10 The urging force of 22 urges the rail plate 9 upward via the fixing pin 20a of the rail plate 9, but the fixing pin 20a of the rail plate 9 is aligned in a horizontal row with respect to the fixing pin 20b of the guide plate 10. After the position shown in FIG. 7 is exceeded (after the fulcrum is exceeded), the urging forces of the first and second compression coil springs 21 and 22 Biasing the rail plate 9 downward through a fixed pin 20a of Rupureto 9.

  Accordingly, the curve slide mechanism 8 is shown in FIG. 7 in which the fixing pin 20a of the rail plate 9 is arranged in a horizontal line with respect to the fixing pin 20b of the guide plate 10 from the open state shown in FIG. When it is manually pulled back until the position shown is exceeded, the rails are then moved through the fixed pins 20a of the rail plate 9 by the biasing forces of the first and second compression coil springs 21 and 22 of the biasing mechanism 14. The plate 9 is urged downward, the rail plate 9 is slid downward with respect to the guide plate 10, and the front casing 2 is slid along the front surface 3a of the rear casing 3. . Then, as shown in FIG. 5, the guide plate 9 is held at the original downward curve slide end position (open position). Therefore, the curve slide mechanism 8 holds the front casing 2 in the closed position shown in FIG. 1A and maintains the closed state of the slide type mobile phone 1.

  By the way, such a curve slide mechanism 8 has a curve slide of the rail plate 9 to cause a distance between the biasing mechanism connecting portion of the rail plate 9 and the biasing mechanism connecting portion of the guide plate 10 (in the thickness direction of the curve slide mechanism 8). Distance: see FIG. 8) L is not constant and varies. In other words, when the fixed pin 20a of the rail plate 9 moves to the position shown in FIG. 7 aligned in a horizontal row with respect to the fixed pin 20b of the guide plate 10 in accordance with the curve slide in the vertical direction of the rail plate 9 with respect to the guide plate 10. The distance L becomes the shortest, and the distance L gradually increases as the distance from the position shown in FIG. 7 where the fixing pins 20a of the rail plate 9 are arranged in a horizontal line to the fixing pins 20b of the guide plate 10 is moved up and down.

  On the other hand, the curve slide mechanism 8 has a planar structure instead of the conventional torsion coil spring as an urging member, and is very thin (for example, the wire diameter of the torsion coil spring and the linear motion of the torsion coil spring). Using a biasing mechanism 14 (substantially equivalent thickness), the distance between the rail plate 9 and the guide plate 10 is reduced, and the curve slide mechanism 8 is thinned (that is, the slide type mobile phone 1 is thinned). However, due to the fluctuation of the distance L accompanying the curve slide, the urging mechanism 14 is bent due to a bending load to bend the urging mechanism 14 in a Z shape, and the urging mechanism 14 is damaged. ,I can not use it.

  Therefore, the curve slide mechanism 8 is provided with means for absorbing the deflection of the urging mechanism 14 accompanying the curve slide of the rail plate 9.

  As such a deflection absorbing means of the urging mechanism 14, a first urging mechanism deflection absorbing means (corresponding to the invention according to claim 1) shown in FIGS. 5 to 14, and FIGS. 15 to 17. There is a bending absorbing means (corresponding to the invention according to claim 2) of the second urging mechanism 14 shown.

  The first biasing mechanism deflection absorbing means shown in FIGS. 5 to 14 includes a pressing surface 33 of the head 29 of the fixing pins 20a and 20b and a pressed surface 34 of the plate-like locking portions 26a and 26b. . The holding surface 33 of the head 29 of the fixing pins 20a, 20b is formed in a spherical convex surface, and the pressed surface 34 of the plate-like locking portions 26a, 26b is a spherical concave surface with substantially the same curvature so as to follow the pressing surface 33. The holding surface 33 and the pressed surface 34 are overlapped in a spherical shape and slide, so that the fixing pin 20a of the rail plate 9 and the fixing pin 20 are fixed to the guide plate 10 according to the variation of the distance L accompanying the curve slide. While the inclination of the urging mechanism 14 is changed between 20b, the bending of the urging mechanism 14 accompanying the curve slide of the rail plate 9 is absorbed.

  By such a first urging mechanism deflection absorbing means, a very thin urging mechanism 14 having a planar structure and linearly extending and contracting on one plane is used as the urging member of the curve slide mechanism 8. It becomes possible to provide a thinner curve slide mechanism 8 (that is, the slide type mobile phone 1) than the conventional one, and the structure of the urging mechanism 14 is complicated by the first urging mechanism bending absorbing means. Therefore, the thickness of the urging mechanism 14 is not impaired, and the urging mechanism 14 can effectively reduce the thickness of the curve slide mechanism 8 (that is, the slide type mobile phone 1).

  The pressing surface 33 of the head 29 of the fixing pins 20a and 20b is located at the innermost part of the U-shaped grooves 26a and 26b 'on the surface of the plate-like locking portions 26a and 26b opposite to the rail plate 9 and the guide plate 10. Since the periphery is pressed toward the rail plate 9 and the guide plate 10, the innermost portions of the U-shaped grooves 26 a and 26 b ′ on the surface opposite to the rail plate 9 and the guide plate 10 of the plate-like engaging portions 26 a and 26 b are disposed. Since the periphery is the pressed surface 34 of the plate-like locking portions 26a and 26b, at least only the pressed surface 34 may be formed into a spherical concave surface with substantially the same curvature so as to follow the pressed surface 33. In the embodiment, the edge portions of the straight portions of the U-shaped grooves 26a and 26b ′ on the surface opposite to the guide plate 10 are also formed in a circular arc-shaped concave surface from the spherical concave surface of the pressed surface 34, and the fixed pin. 20a, a plate-like locking portion 26a on the shaft portion 28 of 20b, and 26b easily to be fitted.

  The bending absorbing means of the second urging mechanism 14 shown in FIGS. 15 to 17 is a weakening portion for allowing the first and second plate-like movable elements to bend with respect to the plate-like locking portions 26a and 26b. 35. The weakening portion 35 is a surface on the rail plate 9 and guide plate 10 side (surface on the pulling side) of the first and second plate-like movable elements 24 and 25 or a surface on the opposite side to the rail plate 9 and guide plate 10 ( A straight V-shaped crossing over the entire width of the boundary between the plate-like locking portions 26a, 26b and the movable spring receivers 24c, 25c on one of the displacements (the compression side surface in this embodiment). It is formed by a groove (which may be a U-shaped groove or a recessed groove). The first and second plate-like movable elements 24 and 25 are bent with respect to the plate-like locking portions 26a and 26b by the weakening portion 35, so that the rail plate 9 is fixed according to the variation of the distance L accompanying the curve slide. The bending of the urging mechanism 14 accompanying the curve slide of the rail plate 9 is absorbed while changing the inclination of the urging mechanism 14 between the pin 20a and the guide plate 10 between the fixed pins 20b.

  By such a bending absorbing means of the second urging mechanism 14, the same effect as that of the first urging mechanism bending absorbing means can be obtained.

  Further, the pressing surface 33 of the head 29 of the fixing pins 20a and 20b does not need to be formed in a spherical convex surface and may be flat, and the pressed surfaces 34 of the plate-like locking portions 26a and 26b are also flat pressing surfaces. The fixing pins 20a and 20b may be flat so that the holding surface 33 is not a special rivet having a deformed head 29 formed on a spherical convex surface, but has a flat head 29. Rivets can be used.

  It should be noted that the plate-like locking portions 26a, 26b are pressed so that the heads 29 of the fixing pins 20a, 20b do not protrude from the surface of the plate-like locking portions 26a, 26b opposite to the rail plate 9 and the guide plate 10. The surface 34 is formed by being lowered by one step from the surface of the plate-like locking portions 26a, 26b opposite to the rail plate 9 and the guide plate 10. In addition, the edges of the straight portions of the U-shaped grooves 26a and 26b ′ are also formed to be lowered by one step so as to be continuous with the pressed surface 34, and the plate-like locking portions 26a and 26b are easily provided on the shaft portions 28 of the fixing pins 20a and 20b. So that it can be externally fitted.
