The specific embodiment
Fig. 1 has used the block diagram of the related perambulator of a kind of mode of the present invention with holder device for expression.Perambulator 1 has vehicle body 2.It is the bindiny mechanism that main body constitutes that vehicle body 2 has with front leg portions 3, rear legs 4, intersection frame 5 and hand push frame 6.Rotate through making the link that constitutes this bindiny mechanism center on each point of connection, thereby vehicle body 2 can be out of shape between running condition (state among Fig. 1) and folded state (state among Fig. 2 and Fig. 3).Left and right sides front leg portions 3 connects through link 7.Left and right sides rear legs 4 connects through not shown link.In the lower end of front leg portions 3 front-wheel 8 is installed, trailing wheel 9 is installed in the lower end of rear legs 4.
Fig. 6 is used for instruction diagram that lockable mechanism 24 is described., have in the lockable mechanism 24: to shown in Figure 6 like Fig. 4 as the lock pin 30 of locking component; Arc sections 31, it is used in above-mentioned bearing position, the 1st holding position, each position, the 2nd holding position lock pin 30 being retrained.Lock pin 30 extends with the mode that runs through supporting leg 22.Lock pin 30 with its relatively moving on the hand of rotation of supporting leg 22 be prevented from and its with the length direction of this hand of rotation various bearing leg 22 on the state that relatively moves and be allowed to, be set on the supporting leg 22.Lock pin 30 to be being supported towards the state of the direction application of force that approaches arc sections 31, and this supporting be through in the inner space that is accommodated in supporting leg 22, implement as the bearing unit 32 of supporting device.The detailed situation of bearing unit 32 will be narrated below.
As shown in Figure 5, lock wall 35 is extended on the radial direction of arc sections 31.Therefore, collide lock pin 30 through lock wall on bearing position 35, the rotation of (top Fig. 5) is stoped towards the top thereby supporting leg 22 is from bearing position.As long as lock pin 30 collides in the lock wall 35, even then to supporting leg 22 applied moments, lock pin 30 can not break away from from lock wall 35 yet.In other words, lockable mechanism 24 is maintained under the self-locking state.Length direction when the position of lock pin 30 from Fig. 5 along supporting leg 22 moves to the direction of separating with arc sections 31, thereby when on lock wall 35, separating, the locking of supporting leg 22 will be released, thereby the rotation of supporting leg 22 is allowed to.
Each keeps groove 36,37 to be formed the shape of the central side that retreats into arc sections 31.Therefore, when supporting leg 22 moves to the 1st holding position, keep in the groove 36 because lock pin 30 is embedded into the 1st, thereby supporting leg 22 is maintained on the 1st holding position.In addition, when supporting leg 22 moves to the 2nd holding position, keep in the groove 37 because lock pin 30 is embedded into the 2nd, thereby supporting leg 22 is maintained on the 2nd holding position.Each keeps two walls of groove 36,37 not tilt the degree of self-locking can not take place.Therefore, be embedded into each from lock pin 30 and keep the state the groove 36,37, make supporting leg 22 rotations through utilizing power to a certain degree, thereby can make lock pin 30 keep deviating from the groove 36,37, to discharge locking from each.
Fig. 7 illustrates the structure of the bearing unit 32 of the supporting of implementing lock pin 30 etc.Bearing unit 32 is inserted in the internal space S 2 of supporting leg 22 with the mode shown in the arrow among Fig. 7.Be inserted into the bearing unit 32 in the supporting leg 22; Through under the mounting hole 41 corresponding to states on the mounting hole 40 and the side that is formed at supporting leg 22 that are formed on the end thereafter; In above-mentioned mounting hole 40,41, insert not shown rivet, thereby be fixed in the supporting leg 22.
On the top of main part 43, formed above-mentioned liner 28.Main part 43 is provided with location division 47, this location division 47 when being inserted in the supporting leg 22 and the collision of the end face of supporting leg 22 at bearing unit 32, thereby bearing unit 32 is positioned on the desired location.Location division 47 is formed, when the end face of supporting leg 22 and location division 47 collisions, make the axle support holes 49 that is formed on the body 43 and the axle support holes 50 that is formed on the supporting leg 22 consistent.When supporting leg 22 is installed in 21 last times of base portion, in each support holes 49,50, be inserted with bolster 26.
So, owing to the bearing unit 32 that lock pin 30 is supported is incorporated in the internal space S 2 of supporting leg 22 with coil spring 46, thereby can prevent that these parts from exposing to the outside.Thus, owing to can the person of avoiding the use of touch bearing unit 32 or coil spring 46, thereby improved safety, and improved aesthetics.In addition, lock pin 30 with on the direction of axis Ax from outstanding state of supporting leg 22 and the state that on the length direction of supporting leg 22, is allowed to respect to relatively moving of supporting leg 22, be set on the supporting leg 22.Therefore, owing to need not on the Width of supporting leg 22, to guarantee the removable space of lock pin 30, thereby can help the miniaturization of lockable mechanism 24.
To shown in Figure 6, lockable mechanism 24 is provided with like Fig. 4, is used to implement the releasing operation parts 55 of the operation that the locking to the supporting leg on the bearing position 22 discharges.Releasing operation parts 55 cover arc sections 31 with rotatable state through bolster 26, and are installed on the base portion 21.Therefore, because bolster 26 is supported leg 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.
