22 and 55 of releasing operation parts are shared, thereby can reduce the quantity of parts, and help the miniaturization of lockable mechanism 24.

Be formed with on the releasing operation parts 55, as slotted hole 56 guidance unit of lock pin 30 channeling conducts.This slotted hole 56 tilts to oblique below with respect to being formed on the slotted hole 52 on the supporting leg 22 with mode as shown in Figure 6.Therefore, when the top shown in the arrow that makes releasing operation parts 55 in Fig. 6 rotates, lock pin 30 along slotted hole 56 and when being directed, overcome the elastic force of coil spring 46, thereby move to the direction of separating with base portion 21.Thus, lock pin 30 separates from lock wall 35, and then locking is released.

As shown in Figure 5, on the releasing operation parts, be provided with operating portion 58 in going up the out-of-position position from axis Ax.Operating portion 58 with intersect the end abutment of frame 5, thereby when vehicle body 2 from folded state when running condition changes, with intersect make under the state of end collision of frame 5 releasing operation parts 55 towards above rotation (also can with reference to Fig. 1).Therefore, when being retained as the state of stance from the vehicle body 2 that is in folded state through support 2, make vehicle body 2 when running condition changes, releasing operation parts 55 link in intersecting moving of frame 5 and the rotation towards the top, thereby locking is released.Though omitted diagram, on releasing operation parts 55, be provided with abutting part, this abutting part its rotate to locking when being released and supporting leg 22 collide.Releasing operation parts 55 after locking is released further to above when rotating, can supporting leg 22 be rotated to the top through abutting part.Therefore, lockable mechanism 24 vehicle body 2 from folded state to the process that running condition changes, can after locking discharges, supporting leg 22 be further rotated keep in the groove 36 so that lock pin 30 is embedded into the 1st, thereby supporting leg 22 remained on the 1st holding position.Thus, when make vehicle body 2 from folded state when running condition changes, can under need not, automatically supporting leg 22 be changed to the 1st holding position from bearing position through the condition of manually coming releasing operation parts 55 are operated.

Described in as described above, according to holder device 20, the lock pin 30 through lockable mechanism 24 collides on the lock wall 35, thereby makes supporting leg 22 by locking mechanically.And, owing on the length direction of supporting leg 22, move in face of coil spring 46 through lock pin 30, thereby lock pin 30 is separated from lock wall 35, thereby the locking of supporting leg 22 is released.Therefore; Can guarantee the intensity of the locking of supporting leg 22 fully, and, because the intensity of the locking of supporting leg 22 is directly not related with the operability that locking is discharged; Thereby can under the condition of not damaging operability, improve the maintenance performance of the stance of perambulator 1

In addition, because the locking of the supporting leg 22 of holder device 20 can not discharged easily, thereby can freely supporting leg 22 inclination alpha with respect to ground G on bearing position be set with mode shown in Figure 8.Thus; Even not with the length setting of supporting leg 22 more than necessary length, also can dwindle its inclination alpha, therefore with respect to ground G; When vehicle body 2 is remained in stance, can guarantee contact to earth distance B position Xb of position Xa of contacting to earth fully to foot 23 from trailing wheel 9.Therefore, can the length setting of supporting leg 22 stably not remained in stance with vehicle body 2 under the condition more than the necessary length.

In above mode, trailing wheel 9 is equivalent to wheel involved in the present invention, rear legs 4 is equivalent to shank involved in the present invention.But the present invention is not limited to above mode, and can implement through variety of way.The perambulator of holder device involved in the present invention can be used,, and the perambulator that trailing wheel contacts to earth must not be so long as the perambulator that any side when the vehicle body that makes folded state becomes stance, in front-wheel or the trailing wheel contacts to earth gets final product.

Lockable mechanism is not limited to aforesaid way.As the releasing operation parts that are set on the lockable mechanism, can implement through for example Fig. 9 or mode shown in Figure 10.Fig. 9 is the block diagram of other modes of expression releasing operation parts.The mode of Fig. 9 does, is set at the mode that releasing operation parts 60 are installed on the both ends of the lock pin 30 on the supporting leg 22.Because releasing operation parts 60 are one with lock pin 30, thereby through releasing operation parts 60 are operated to the length direction of the supporting leg 22 shown in the arrow of Fig. 9, thereby lock pin 30 moves end wise, therefore, can locking be discharged.The releasing operation parts 60 of Fig. 9 also can form with lock pin 30, thereby can help the miniaturization of lockable mechanism.

Figure 10 is the block diagram of other modes of the expression releasing operation parts different with the mode of Fig. 9.The mode of Figure 10 has, and is loaded in the releasing operation parts 61 of the tubulose on the periphery of supporting leg 22 with the state that can be rotated around the centre line C L of supporting leg 22.Releasing operation portion 61 is provided with the threaded hole 62 as guidance unit, and this threaded hole shape ground is in the shape of a spiral extended, thereby can lock pin 30 moved towards the below of the length direction of supporting leg 22 making releasing operation portion 61 when the direction of arrow of Figure 10 is rotated.In addition, though in fact on the both ends of lock pin 30, respectively be provided with a threaded hole 62,, only illustrate of side nearby owing to graphic reason.On the releasing operation parts 61, upwards roughly equally spaced be set side by side with a plurality of protrusions 63 that on its length direction, extend, with as Non-slip material in week.According to the mode of Figure 10, because releasing operation parts 61 that can be through making tubulose are rotated the release that realizes locking round the centre line C L of supporting leg, therefore to compare with other modes, its space efficiency is excellent.

In addition, when embodiment of the present invention, the releasing operation parts are not to be provided with.Therefore, also can come embodiment of the present invention with the mode of the releasing operation component omission that aforesaid way is related.In addition, as locking component, be not the lock pin that is necessary for a shape, the shape of locking component can be a shape arbitrarily.The moving direction of locking component is set to the length direction of supporting leg, only an example.For example, also can be as shown in Figure 1, implement holder device as follows, that is, have: locking component 65, it is allowed to respect to relatively moving of supporting leg 22 on the direction as the axis Ax of the centre of gration of supporting leg 22; Coil spring 66, it is as the application of force unit to locking component 64 application of forces.In addition, under the situation of the mode that adopts Figure 11, also can on the desired location in the mobile route of locking component 65, for example be provided with lock wall 67 in the desired location of base portion 21.

Locking component is provided with the state that can relatively move with respect to supporting leg, only an example.For example also can come embodiment of the present invention as follows, that is, locking component is not being fixed on the supporting leg with respect to the mode that supporting leg relatively moves.Figure 12 does, is used for the instruction diagram that other modes to the lockable mechanism different with the mode of Figure 11 describe.The lockable mechanism 80 of Figure 12 is installed on the base portion 21 with following state; Said state does; Can not being fixed on the supporting leg 22 with respect to the mode that supporting leg 22 relatively moves, and supporting leg 22 can be rotated and can on its length direction, move round axis Ax as the lock pin 81 of locking component.Be formed with on the supporting leg 22, have width that can make bolster 26 insertions and the slotted hole 82 that extends at length direction.Through in this slotted hole 82, inserting bolster 26 so that this bolster 26 is fixed on the base portion 21, thereby the state of supporting leg 22 being rotated and can end wise moving round axis Ax is installed on the base portion 21.Thus, lock pin 81 becomes, on length direction as predetermined direction, and the state that can relatively move with respect to base portion 21.Therefore, move, thereby can discharge the locking of lockable mechanism 80 through on the length direction shown in the arrow of Figure 12, directly making supporting leg 22.As long as vehicle body is remained in stance, just be applied with on the lockable mechanism 80, as the power that the state of lock pin 81 and lock wall 35 collisions is kept from ground-surface counter-force and at graphic bearing position place.Therefore, even on lockable mechanism 80, do not set application of force unit, also can realize function as lockable mechanism.Therefore, lockable mechanism 80 can be avoided the complicated of structure, and helps the minimizing of number of components.
