Description

  The present invention relates to a slide device and an electronic device such as a mobile phone, a mobile, and a small personal computer using the slide device.

  For example, an operation unit in which numeric keys and function keys are arranged is provided on the upper surface of the main body, and a display unit such as a liquid crystal panel for displaying a predetermined display is provided on the upper surface of the superposition unit superposed on the main body. A slide type with a structure in which the main body part and the overlapping part slide relative to each other in the front-rear direction, a rotating slide type that rotates and slides in the direction of the overlapping surface, and a combination of these slides and a 90-degree turn slide after opening the slide into a T-shape Conventionally, there has been a mobile phone or the like that can be used by switching its rotation.

  For example, in this slide type, a guide rail portion as a slide guide portion is provided directly or indirectly (meaning including a member provided in the main body portion) with an interval between the left and right overlapping portions, and the left and right guide rail portions are provided. A slide portion that is slidably engaged is provided directly or indirectly on the main body portion, and the slide portion is slid relative to the guide rail portion so that the overlapping portion and the main body portion are slidably connected.

  A slide device that realizes such a slide-type mobile phone slide structure has a slide portion that is slidably engaged between slide guide portions provided on the left and right sides, as described above, with respect to the main body portion. Thus, the overlapping portions are slidably connected.

  In the case of a rotating slide type, for example, a slide guide portion such as an arc-shaped guide groove that serves as a guide when rotating with the fulcrum portion as a rotation fulcrum is provided in the main body portion, and the overlapping portion rotates to this slide guide portion. A slide part that is slidably engaged is provided, and is pivotally attached at a pivotal fulcrum part. At the same time, the guide part is pivotally slidably engaged with the slide guide part, and the overlapping part is pivotally slidably connected to the main body part. It is the structure to do.

  By the way, in the slide type or rotary slide type mobile phone using the slide device that slidably or rotatably slides the main body part and the overlapping part in this way, the operation part of the main body part is concealed by the overlapping part. Positioning and holding at the overlapped closed position and the slide open position where the operation part is exposed by moving it in the front-rear direction or rotational direction so as to shift the overlapped part (close biasing or opening biasing or click engagement) It is desirable to make it so.

  Therefore, in order to meet such a demand, one end of the elastic portion is directly or indirectly connected to the first member and the other end is directly or indirectly connected to the second member. Thus, there is a slide device configured to generate a return bias (close bias) or a forward bias (open bias) between the first member and the second member.

  That is, for example, the wire is wound in a coil shape or a spiral shape in the middle between both ends of the wire, and the torsion spring formed in a generally square shape with the wound portion at the top is used as an elastic portion. One end of the spring is connected to the first member, the other end is connected to the second member, and the connecting portions at both ends of the torsion spring are separated from each other by the spring bias (expansion bias) to the first member. In some cases, when the second member is slid or rotated, the urging force is generated in the sliding direction.

  According to this conventional apparatus, by using the urging in the sliding direction resulting from the angle expansion urging of the elastic portion, for example, when the overlapping portion is slid with respect to the main body portion of the sliding mobile phone, the predetermined sliding movement position Until this position is maintained at the overlapped position so that a closed bias is generated, and when the overlapped portion is moved beyond the predetermined slide movement position with respect to the main body, this time, an open bias is generated in reverse. A positioning and holding function of positioning and holding the overlapping portion at the slide open position can be realized.

JP 2005-291315 A

  In this type of slide device, as the elastic portion, the torsion spring or the like that generates the above-described widening bias is employed because it is easy to manufacture and low in cost, and is thin and easy to assemble.

  On the other hand, in order to increase the elastic force (biasing force), it is necessary to increase the number of windings of the wire. However, if the winding diameter is the same diameter and a plurality of windings are made into a coiled winding part, the wire is wound only by the number of windings. Since it overlaps in the vertical direction, it will not be able to respond to thinning.

  For this reason, for example, a torsion spring having a spiral winding portion that can be wound in a flat shape so as not to overlap as much as possible in order to increase the elastic force while realizing thinning has been proposed.

  In other words, if you want to strengthen the urging force in the sliding direction such as return urging and forward urging, you can bend it into a flat and thin overall view (plan view) by winding it several times in a spiral shape. It is configured such that a strong energizing force is generated by energizing and energizing both ends of the unwinding spring by bringing them closer to each other and connecting them.

  However, the conventional elastic portion (torsion spring) composed of a spiral wound portion that generates this strong biasing force is generally wound a plurality of times in a spiral shape so that the diameter gradually decreases from the outside to the inside, for example. Due to the structure of unwinding from the winding center, the deformation strength at the left and right with the winding center as the boundary is different, and the right and left balance of the spring bias may be poor and stress concentration may occur. Due to the poor quality, the winding part may bend in the vertical direction, causing the winding part to contact the surface of the member, causing unnecessary slide resistance, or unstable movement, for example, the winding part with respect to the connected winding wire There is a concern that the winding of the winding part may be caught by a member that moves relative to the winding part and may not slide smoothly, or the member surface may be scratched or generate abnormal noise.

  That is, the torsion spring having a generally square shape is flat and can be thinned, but as shown in FIG. In particular, one of the winding lines wound in a left-right shape with the spiral winding portion at the apex is unwound from the outside of the spiral winding portion, while the other is unwound from the spiral center portion (vortex winding). Although it is easy to manufacture and excels in mass productivity, it is easy to manufacture and has a structure where the center part is connected to the base of the unwinding line. (When the spring is operated in which the left and right unwinding lines of the spring expand or contract against the bias), the unwinding angle of the base of the unwinding line is not the same on the left and right, and the bases of the left and right unwinding lines are Since the winding diameters of the continuous unwinding portions are completely different, the deformation strength at the unwinding line receiving the force is different, and the balance between the left and right in the spring bias is not uniform, causing deflection in the vertical direction.

Therefore, as described above, there is a possibility that the sliding operation and the durability of the spring may be hindered. In particular, as shown in FIGS. 13 and 14, one of the first member and the second member is provided with a slide guide portion 7 as a guide portion, and the other is provided with a slide portion 7 as a guide portion slidably engaged therewith, A slide part that scratches or moves the surface of the slide guide part 7 that may be an exposed surface as the torsion spring 3 provided between the first member and the second member bends up and down. 7 There is a possibility that the slide movement may not be smooth due to being caught on the front edge, or that the slide cannot be performed.

  The present invention finds that the spiral toroidal torsion spring that can easily realize a thin and strong biasing force has the above-mentioned problems, and this is simply a predetermined product that is excellent in mass productivity. The problem is solved by attaching the reinforcing plate to at least one of the unwinding lines. Even if the spring shape is thin and easily generates a strong urging force, for example, the shape of the flat plate is not limited to this but is generally flat. (For torsion springs), the vertical deflection is reduced, so that smooth slides can be realized, defects such as scratches, abnormal noise and durability are less likely to occur, and the urging force increases further. In other words, the spring load also increases. It is an object of the present invention to provide a revolutionary elastic part that can be expected to be extremely excellent, thereby providing a revolutionary slide device and an electronic device using the slide device.

  The gist of the present invention will be described with reference to the accompanying drawings.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  The elastic portion 3 according to the present invention is formed of a flat and generally bendable spring having a connecting end 4 on the left and right sides and a winding portion 5 in the middle. One end of the connecting end 4 is directly or indirectly connected to the first member 1 and the other end is directly or indirectly connected to the second member 2 so as to cause an expansion urging force that causes the connecting ends 4 to be separated from each other. However, at least one of the windings 6 of the elastic part 3 that causes an expansion bias between the left and right windings 6 has a flat direction in the plate surface direction. Since the reinforcing plate 8 having a horizontal width and a vertical width in the length direction of the unwinding line 6 is attached, at least the deformation strength (at least deflection strength) by the reinforcing plate 8 is reinforced and the winding portion 5 becomes difficult to bend in the vertical direction perpendicular to the flat direction.

  Further, the unwinding line 6 provided with the reinforcing plate 8 is less likely to be bent and deformed in the flat direction with respect to the winding part 5 of the elastic part 3.

  That is, the shape setting of the reinforcing plate 8 by the setting of the longitudinal width in the length direction of the unwinding line 6 and the setting of the lateral width in which the unwinding line 6 becomes wide in the flat direction of the flat elastic portion 3 or Due to the shape setting of the reinforcing plate 8 and the overlapping arrangement of the reinforcing plate 8 and the winding portion 5, the deformation strength of the unwinding wire 6 (the bending strength of the elastic wire 3 in the vertical direction and the bending strength of the unwinding wire 6). Thus, at least deflection prevention (and spring load) can be increased.

  Therefore, simply by attaching a thin plate-like reinforcing plate 8 of a predetermined size excellent in mass productivity to the unwinding wire 6 of the elastic part 3 (for example, the unwinding wire 6 is pressed against the reinforcing plate 8 by superposition. If it is configured to be one-touch engaged, it can be prevented from being bent during the spring operation while responding to the demand for thinning (simply by simply press-fitting and retrofitting to the unwinding line 6 of the elastic portion 3). The winding part 5 bends up and down at the time of the spring operation and the upper and lower members do not rub against each other and do not rub or get caught by the member. There will be no hindrance, no damage to the member, no abnormal noise will occur, and the durability will be excellent.

  Further, for example, it is possible to suppress the deflection only by attaching the reinforcing plate 8 to the spiral torsion spring having a general shape that is spirally wound in the middle of the wire so as to easily manufacture and generate a strong bias. it can.

  That is, as explained in the prior art, the left and right unwinding lines 6 have a large unwinding angle and a large diameter at the unwinding position between the outer side and the center part, and therefore the left and right biasing balance is poor. Although there is a risk of bending up and down during the spring operation, in the present invention, the left and right urging balance can be made nearly uniform simply by providing the reinforcing plate 8, and this also can reduce the vertical deflection during the spring operation.

  Therefore, for example, as shown in the illustrated embodiment, a plate-like slide guide portion 7 having both side edges as guide rails is provided as a guide portion 7 on one of the first member 1 and the second member 2, and the other can slide on this. A plate-like slide portion 7 that engages with the first member 1 is provided as a guide portion 7, and the elastic portion 3 is provided between the slide guide portion 7 and the slide portion 7 between the first member 1 and the second member 2. When the both ends are connected to the members 1 and 2 via the guides 7 respectively, the slide guide 7 can be damaged by bending up and down, or the plate edge of the slide that slides. It is possible to prevent the elastic part 3 from being caught on the (front end edge) and preventing the slide from smoothly moving or not being able to slide.

  In addition, not only can the urging balance of both the unwinding wires 6 be equalized, but also an increase in the spring load can be expected, which makes it possible to generate a large urging force even with the same size and the same number of turns, Accordingly, it is possible to design the device so that a large biasing force can be realized more easily by flattening.

  Further, if a part of the reinforcing plate 8 is superposed on the winding portion 5, further deflection can be prevented and an extremely excellent torsion spring can be obtained.

  Further, by setting the engagement configuration between the reinforcing plate 8 and the unwinding line 6, the reinforcing plate 8 can be easily retrofitted or reduced in thickness. For example, the reinforcing plate 8 can be set to be as thin as the thickness of the unwinding wire 6 except for a part, and the portion where the unwinding wire 6 overlaps with the winding of the winding portion 5 is The base plate portion 10 having the same thickness is superposed to set the reinforcing plate 8 as long as the length of the unwinding wire 6, and the unwinding wire 6 is pressed (press-fit) into the linear engaging portion 9 so that it can be retrofitted. Even if the reinforcing plate 8 is engaged and attached, the reinforcing plate 8 can be set long, and a part of the reinforcing plate 8 can be superposed on the winding portion 5, and it can be thinned as before while achieving an extremely high deflection preventing effect and a spring load increasing effect. The shape can be maintained.

  Thus, for example, the right and left biasing balance is good by setting the shape of the reinforcing plate 8 and the engagement configuration with the unwinding line 6, the right and left deformation strength is equalized, and there is almost no vertical deflection, In addition, the urging force can be strengthened, and if the reinforcing plate 8 is set long and overlapped with the winding portion 5 as described above, it is possible to reduce the deflection and increase the spring load while reducing the thickness as usual. The shape can be maintained.

  Specific embodiments of the present invention will be described with reference to the drawings.

  In the first embodiment shown in FIG. 1 to FIG. 11, a guide portion 7 provided on a second member 2 (overlapping portion 2) is provided on a slide portion 7 as a guide portion 7 provided on a first member 1 (main body portion 1). The first member 1 and the second member 2 are slidably engaged with each other in the overlapping direction, and one end is connected to the first member 1 via the slide portion 7. And the other end of the elastic member 3 is connected to the second member 2 via the slide guide portion 7, and the elastic force of the elastic member 3 is biased by the elastic force of the first member 1 and the second member 2. It is a slide device configured to generate a bias in the sliding direction, that is, a return bias (close bias) or a forward bias (open bias), and the elastic portion 3 winds in the middle of the wire A flat, flat-shaped bendable bar having a connecting end 4 on the left and right and a winding part 5 in the middle. The one end of the connecting end 4 is connected to the first member 1 and the other end is connected to the second member 2 such that the left and right connecting ends 4 cause an expansion bias that tends to be separated from each other. Yes.

  Hereinafter, the present embodiment will be specifically described.

  In this embodiment, the main body part 1 and the superposition part 2 are superposed, and the superposition part 2 is slid so as to pass relatively to the superposition surface direction from this superposed state to expose a part of the superposition face. The present invention is applied to an electronic device in which the main body 1 and the overlapping portion 2 are connected by a slide device so that the present invention can be applied. Specifically, the present invention is applied to a slide-type mobile phone. A main body portion 1 provided with an operation portion having keys and function keys arranged on the upper surface side is used as a first member 1, and a second overlapping portion 2 is slidably overlapped thereon to open and close the operation portion so as to be hidden and exposed. As a slide device for connecting the first member 1 and the second member 2 to each other in a freely slidable manner, the second member 2 is provided with a display unit such as a liquid crystal panel on the upper surface. Yes.

  In this embodiment, a slide device that slidably couples the second member 2 (overlapping part 2) superposed on the first member 1 (main body part 1) in the overlapping surface direction via the guide part 7, Or, for example, as shown in FIG. 12, in addition to this sliding type, it is a slide device that is connected to be freely slidable in the direction of the overlapping surface, but in this embodiment shown in FIGS. 1 to 11, both sides are folded back. A plate-shaped slide guide portion 7 formed and provided with a guide rail portion is provided on the back surface of the second member 2 (overlapping portion 2), and the edge portion is slidably engaged with the guide rail portion of the slide guide portion 7 A plate-like slide portion 7 provided on both sides is provided at a position where it overlaps with the overlapping portion 2 on the upper surface of the first member 1 (main body portion 1), and the slide guide portion 7 and the slide portion 7 The elastic part 3 is disposed between the two ends, First member 1, respectively connected to the ends 4 and the slide guide portion 7 and the slide portion 7 to be connected to the second member 2. At this time, when the second member 2 is slid back and forth with respect to the first member 1, the front edge portion of the slide portion 7 is relatively moved along the winding portion 5 of the elastic portion 3 in this embodiment. The vertical movement of the winding portion 5 is suppressed so that the front edge portion is not caught by the winding portion 5.

  In other words, to be repeated, the elastic portion 3 is wound in the middle of the wire as described above, and has a flat end having a connecting end 4 on the left and right and a winding portion 5 in the middle, and is bendable in the shape of an overall character. The connecting end 4 is connected to the first member 1 via the slide portion 7 and the other end is connected to the first member 1 so that the right and left connecting ends 4 are separated from each other. The second member 2 is connected via the slide guide portion 7.

  Further, until the second member 2 is slid by a predetermined length with respect to the first member 1, the second member 2 is moved by an angled biasing force in the sliding direction by the elastic portion 3 having a generally U-shape. A return urging force that returns is generated, and when the slide member is slid for a predetermined length, a reverse urging force that causes the second member 2 to move forward is generated.

  In other words, the overlapping surface of the first member 1 is exposed by sliding the second member 2 relative to the first member 1 from the overlapping state where the second member 2 covers and closes the first member 1. And the left and right connecting ends 4 of the elastic portion 3 are pressed in a direction approaching each other to connect one end of the connecting end 4 to the first member 1 and the other end The elastic member 3 is connected to the second member 2 so as to generate an expanded urging force that causes the connecting ends 4 to be separated from each other, and the expanded urging force generated at the left and right connecting ends 4 slides. During the sliding movement of the second member 2 to the sliding position with respect to the first member 1 at the boundary of the sliding position that does not act as a moving force, a closing bias is generated in the second member 2 by this widening bias, Slide it to a position beyond this slide position Urged open by the expansion angle urging the second member 2 is configured to produce a.

  Further, as shown in FIG. 12, by providing this slide device even in the case of rotating slide, positioning bias is generated by the rotation return bias at the rotation slide starting position (the slide opening position), and it is rotated 90 degrees. It may be configured such that a positioning bias is generated by a rotational advance bias at a rotational position that is slid and becomes T-shaped.

  The elastic part 3 which is the main part of the present invention is configured such that the winding part 5 is wound in a spiral shape so that the diameter gradually decreases, and the wire wound from the outside is unwound from the winding center part.

  That is, the left and right unwinding wires 6 having the connecting end 4 at the tip, and the left and right unwinding wires 6 are connected to the left and right unwinding wires 6 so as to be positioned substantially in the same plane (on one side the winding wire The winding wound in a spiral shape so that the wire does not overlap vertically and the spiral winding portion 5 and the one winding wire 6 wound from the outside are completely located in the same plane) The winding portion 5 is wound from the winding center portion so that the diameter gradually decreases from the outside to the inside continuously connected to the base portion of the one winding wire 6. It is set as the structure connected with the other unwinding line 6. FIG.

One unwinding line 6 unwound from the turning part 5 and provided with the one connecting end 4 at the tip thereof is orthogonal to the unwinding line 6 with the flat direction of the flat elastic part 3 as the plate surface direction. A reinforcing plate 8 having a horizontal width in the direction and a vertical width in the length direction of the unwinding line 6 is attached.

  That is, in this embodiment, substantially all of the one winding wire 6 (including the connecting end 4 formed by curling the tip) is superposed on the reinforcing plate 8 from the connecting end 4 to the winding of the winding portion 5. A linear engaging portion 9 (substantially all of the base end portion) is press-fitted and engaged (the portion into which the connecting end 4 is press-fitted is an opening engaging portion 13 that matches the curl shape). The reinforcing plate 8 is attached by press-fitting the unwinding wire 6 to the joint portion 9.

  The linear engaging portion 9 is set to a depth that matches the thickness (diameter) of the unwinding wire 6, and the reinforcing plate 8 as a whole is within twice the thickness (diameter) of the unwinding wire 6. The thickness is assumed to be.

  More specifically, the longitudinal length of the unwinding wire 6 is set to be sufficiently long until it reaches the vicinity of the center of the winding portion 5 as described above, and the unwinding wire 6 has the flat elastic shape. The width of the portion 3 which is wide in the flat direction is also set to a sufficiently wide width which is more than three times the line width of the unwinding line 6, and in the present embodiment, the shape setting of the reinforcing plate 8 and the reinforcing plate 8 Due to the overlapping arrangement with the winding portion 5, the unwinding wire 6 provided with the reinforcing plate 8 is less likely to bend and deform in the flat direction with respect to the winding portion 5 of the elastic portion 3, and the winding The turning portion 5 is configured to be less likely to bend in the vertical direction perpendicular to the flat direction, thereby reinforcing the deformation strength of the unwinding wire 6.

  More specifically, in the present embodiment, a slit portion slightly narrower than the unwinding line 6 is provided as a linear engaging portion 9 on the base plate portion 10 that matches the thickness of the unwinding line 6 of the reinforcing plate 8. The continuous portion 12 provided continuously to the left and right portions of the slit portion 9 is provided to form a slit bottom portion 15, and the unwinding line 6 is overlapped and pressed into the slit portion 9 so as to be press-fitted and engaged in a flush manner.
