As the wire rod 145 of the second flat application of force unit 4b, use generally to be used for for example wire rod etc. of torsion spring or compression spring of spring.In addition, the cross sectional shape of wire rod 145 is not particularly limited, and for example can enumerate the cross section is that rectangle and cross section are shapes such as ellipse for circular, cross section for square, cross section.Thereby this wire rod 145 crooked zigzag part 141 that formed on the Width of first housing 11 or second housing 12.Preferably form zigzag part 141 like this: for example at first form near the coiling portion 142 that as torsion spring, reels a circle end of wire rod 145 and constitute, form bend 143 then, then form coiling portion 142, bend 143 successively continuously, make the linearly effect of active force.
In this case, according to the coiling direction of wire rod 145,, two kind of second flat application of force unit 4ba, 4bb have been formed as Figure 11 and shown in Figure 12.The both ends of the second flat application of force unit 4ba, 4bb for example form circle or bending or circular-arc, in examples shown, form circular-arc, and as installation portion 144 formation of pivot suspension (installations) rotationally in the periphery of the axial region 115a of installation shaft 115.The length of the length direction of the second flat application of force unit 4ba, 4bb is preferably formed to more than or equal to the length between second installing hole 37 of an end side of first installing hole 27 of an end side that is in the base member 2 under the closed condition and sliding part 3, for example forms the size greater than this length.
The installation portion 144 of this second flat application of force unit 4b is installed around the axle of the axial region 115a of installation shaft 115, this installation shaft 115 is installed in one first installing hole 127 of base member 2, and another installation portion 144 of the second flat application of force unit 4b is installed around the axle of the axial region 115a of installation shaft 115, and this installation shaft 115 is installed in one second installing hole 137 of sliding part 3.Unit 4b is installed in equally respectively on the installation shaft 115 with another second flat application of force, and these installation shaft 115 are installed in respectively in another first installing hole 127 and second installing hole 137.Overcome active force when thus, two second flat application of force unit 4b are in off position with open mode and bend to roughly circular-arc (with reference to Fig. 8 and Figure 10.), and when intermediateness, further overcome active force and bend to circular, substantially elliptical, roughly Long Circle etc. is (with reference to Fig. 9.)。As these two second flat application of force unit 4b, can use the identical parts of coiling direction, also can use the different parts of coiling direction as shown in the figure.
Next the effect of slide mechanism 1 of the present invention and pocket telephone 10 is described.
Under the state that does not use pocket telephone 10, as shown in Figure 1, first housing 11 and second housing 12 are the closed conditions that overlap.At this moment, as Fig. 1 and shown in Figure 8, owing to two flat application of force unit 4 overcome its active force bend to circular-arc, so by this active force, base member 2 and sliding part 3 are applied sliding force to closing direction, therefore first housing 11 and second housing 12 are remained closed condition.In addition, in order to keep this closed condition more reliably, locking mechanism can be set.
In order to converse with this pocket telephone 10 etc., for example under the fixing state of first housing 11, second housing 12 is slided to opening direction.Like this, contraction in length between the both ends of flat application of force unit 4, that is, the power when second housing 12 is slided acts on flat application of force unit 4 by the both ends of flat application of force unit 4, and is further crooked thereby flat application of force unit 4 bears load and overcomes its active force.
Then, as Fig. 2 and shown in Figure 9, length minimum between the both ends of flat application of force unit 4, promptly the two-end part of flat application of force unit 4 is on the straight line that extends along the Width of first housing 11 or second housing 12 time, and flat application of force unit 4 is bent into minimum.This state is a neutral condition, when having served as this neutral condition, and the place-exchange at the both ends of flat application of force unit 4, and by active force, flat application of force unit 4 will revert to original shape.Promptly, since the both ends of flat application of force unit 4 by to mutually away from the direction application of force, so first housing 11 and second housing 12 automatically to open direction slide mutually mobile, as shown in Figure 3, first housing 11 and second housing 12 become open mode, and keep this state.Thus, the keypad portion 11a that is located at the upper surface of first housing 11 exposes, thus just can converse and keyboard operation, thus become the state that can use that pocket telephone 10 is conversed etc.In addition, in order to keep this open mode more reliably, also locking mechanism can be set.Thus, when sliding when mobile to open mode, can semi-automatically carry out sliding action from closed condition.
In order to make second housing 12 return original position, for example under the state that first housing 11 is fixed, second housing 12 is slided to closing direction.Like this, contraction in length between the both ends of flat application of force unit 4, when having served as neutral condition, the both ends of flat application of force unit 4 by to mutually away from the direction application of force, so first housing 11 and second housing 12 automatically slide mobile to closing direction mutually, as shown in Figure 1, first housing 11 and second housing 12 keep closed condition.Thus, when sliding when mobile to closed condition, can semi-automatically carry out sliding action from open mode.
Flat application of force unit 4 is owing to being the first flat application of force unit 4a or the second flat application of force unit 4b, so can reduce whole thickness.That is, under the situation of using torsion spring or compression spring, the active force of these springs is by the decisions such as diameter of wire rod, so wanting to realize that when slim, the diameter of wire rod reduces, the active force of spring can weaken, and therefore can not realize slimming.
Relative therewith, the first flat application of force unit 4a or the second flat application of force unit 4b are when making sliding part 3 slide with respect to base member 2, on the Width of first housing 11 or second housing 12, overcome active force and bending, and utilize this active force with respect to 2 pairs of sliding parts 3 of base member from the neutral position to closing direction or open direction and apply sliding force, so this active force is by the shape decision of corrugated that forms on Width or zigzag part 141.That is, the active force of the first flat application of force unit 4a or the second flat application of force unit 4b is relevant with width and irrelevant with thickness, get final product so just widen width under the situation that strengthens its active force, and thickness can be constant.In addition, among the second flat application of force unit 4b since coiling portion 142 and bend 143 forms continuously, so can dispersive stress concentrated, be that one situation is compared with coiling portion 142 and bend 143, can humidification power.In addition, coiling portion 142 is in contact with one another or closely for example is equipped with seven among the second flat application of force unit 4b, and bend 143 is adapted to, and bend 143 is positioned at the outside when the second flat application of force unit 4b is crooked, thus when the second flat application of force unit 4b is crooked, coiling portion 142 is in contact with one another, so further humidification power.Also can humidification power even do not change whole thickness thus, thus can realize slimming.
Therefore, in the slide mechanism 1 and pocket telephone 10 of portable set of the present invention, flat application of force unit 4 is by forming to such an extent that broad strengthens the active force on this Width on the Width of first housing 11 or second housing 12, so can reduce whole thickness, thereby can realize slimming.
In addition, the first flat application of force unit 4a by changing this undulatory shape and width, can regulate the active force of the first flat application of force unit 4a owing to form corrugated on the Width of first housing 11 or second housing 12.In addition, among the second flat application of force unit 4b since coiling portion 142 be in contact with one another or closely for example be equipped with seven, and bend 143 is adapted to, and bend 143 is positioned at the outside when the second flat application of force unit 4b is crooked, by the diameter of the quantity of increase and decrease coiling portion 142, the position that changes coiling portion 142 or change coiling portion 142, can regulate the active force of the second flat application of force unit 4b.
As mentioned above, in the slide mechanism of portable set of the present invention, because flat application of force unit is by forming to such an extent that broad strengthens the flat application of force unit of the active force on this Width on the Width of first housing or second housing, so can reduce the interval between base member and the sliding part, therefore can reduce whole thickness, in portable terminal, be especially suitable for use as the slide mechanism of pocket telephone.
