In the present embodiment, can from the different vehicle body frame 2 of form under deployed condition (Fig. 1) and under folded state (Fig. 3) in linkage, allow or the rotation of front-wheel 7 as castor that lock.About this structure, describe in detail with reference to Fig. 4 ~ Fig. 6.
Fig. 4 represents the diagrammatic side view of taking out armrest member 5, the forward foot in a step 6, the rear foot 8, the deployed condition (Fig. 1) of corresponding Pushchair 1.The castor locking part 24 being arranged at castor holding member 22 is configured in the position leaving rotation axis X, the groove that such as also vertically can extend along the rear side being formed at castor holding member 22 or hole displacement.And castor locking part 24 releasing position A up leaves castor turning unit 23.At this moment, castor locking part 24 does not have to engage the engaged part 23m being formed at castor turning unit 23.Therefore, castor turning unit 23 is identical with front-wheel 7, and the rotation of its left and right directions is not restricted, and plays the effect of castor.
Engaged part 23m is such as formed at the rear side of castor turning unit 23 and the groove that vertically extends or hole, and the upper end in this groove or hole is open.This opening portion, upper end is towards the lower end of castor locking part 24.Engaged part 23m accepts the bottom of castor locking part 24 to whole.In addition, the cross sectional shape of engaged part 23m is formed as funnel with broadening gradually upward, and therefore, engaged part 23m can accept the lower end (not shown) of the castor locking part 24 fallen from top simply.Thereby, it is possible to make castor locking part 24 and engaged part 23m engage simply.
Forward foot in a step movable member 26 is set near the upper end of the forward foot in a step 6.Forward foot in a step movable member 26 can conjugate along the forward foot in a step 6.In addition, the upper end of the forward foot in a step 6 is provided with elastomeric element 25, elastomeric element 25 is biased forward foot in a step movable member 26 all the time upward.Thus, forward foot in a step movable member 26 is positioned at top position α as illustrated in fig. 4 under the deployed condition of Pushchair 1.Forward foot in a step movable member 26 and castor locking part 24 are connected to each other by pipe link.Pipe link is such as can the strip shape bar 27 of transmitter shaft direction compressive force.As other examples, pipe link is the not metal wool of transmitter shaft direction compressive force and the combination of spring.The lower end of bar 27 connects castor locking part 24, and the upper end of bar 27 connects forward foot in a step movable member 26.Bar 27 preferably can be out of shape by slight curve, also can be applied in the inside of the forward foot in a step 6 being formed as catheter-like.
Abutting part 28 is fixed with in the upper end of the rear foot 8.The top end part of abutting part 28 forwards extends towards the forward foot in a step 6 ground, and with forward foot in a step movable member 26 subtend, but under the deployed condition of Pushchair 1, abutting part 28 leaves forward foot in a step movable member 26.Or abutting part 28 abuts the upper end of forward foot in a step movable member 26 with a little power, forward foot in a step movable member 26 do not pressed (not shown) downwards.Therefore, forward foot in a step movable member 26 is subject to the bias force of elastomeric element 25 and is maintained at top position α.The forward foot in a step 6 shown in Fig. 4 and the rear foot 8 are opened with the angle of regulation.At this moment, with the S. A. from front-wheel 7 to the wheelbase of the S. A. of trailing wheel 9 from Dl for maxim L1.
Under making front-wheel 7 and castor turning unit 23 keep state forward, start the folding operation of Pushchair 1, the angle between the forward foot in a step 6 and the rear foot 8 diminishes gradually, and wheelbase is less than maxim L1 gradually from Dl.At this moment, paying close attention to is positioned at than the armrest member 5 more forward foot in a step movable member 26 of lower position and the position relationship of abutting part 28, when folding operation, abutting part 28 forwards moves and abuts forward foot in a step movable member 26, resists the bias force of elastomeric element 25 and presses down forward foot in a step movable member 26.
Fig. 5 represents the diagrammatic side view of taking out armrest member 5, the forward foot in a step 6, the rear foot 8, folding midway state (Fig. 2) of corresponding Pushchair 1.When the folding midway state specified, such as wheelbase are 3/4L1 from Dl, abutting part 28 presses down forward foot in a step movable member 26 until midway location β.
The midway location β of forward foot in a step movable member 26 is positioned at than top position α more below.Forward foot in a step movable member 26, along with the below displacement of itself, presses down castor locking part 24 by bar 27.Thus, castor locking part 24 is positioned at locking end position B.Locking end position B is positioned at than releasing position A more below, and the bottom of castor locking part 24 passes in and out from castor holding member 22, engages with the engaged part 23m being formed at castor turning unit 23.On locking end position B, the engaging size between castor locking part 24 and engaged part 23m is abundant, achieves castor locking part 24 and engages relative to the substance of castor turning unit 23.Thus, limit castor turning unit 23 to rotate around rotation axis X.
Fig. 6 represents the diagrammatic side view of taking out armrest member 5, the forward foot in a step 6, the rear foot 8, the complete folded state (Fig. 3) of corresponding Pushchair 1.Comparison diagram 5 and Fig. 6 can learn, when carrying out folding operation continuously from folding midway state, the angle between the forward foot in a step 6 and the rear foot 8 and wheelbase reduce further from Dl.Finally, the angle between the forward foot in a step 6 and the rear foot 8 becomes minimum in a folded configuration, and wheelbase is minimum value L3 from Dl.L3 is the specified value be such as comprised within the scope of 1/3L1 ~ 1/5L1.In a folded configuration, forward foot in a step movable member 26 presses down by abutting part 28 completely, and forward foot in a step movable member 26 is positioned at lower position γ.Lower position γ is positioned at than midway location β more below.
Along with the forward foot in a step movable member 26 being positioned at lower position γ, castor locking part 24 is positioned at locking position C.Locking position C is positioned at than locking end position B more below, and castor locking part 24 engages with castor turning unit 23 at locking position C.Thus, limit castor turning unit 23 to rotate around rotation axis X.That is, between locking end position B to locking position C, restriction castor turning unit 23 cannot rotate around rotation axis X.Therefore, front-wheel 7 keeps forward, and Pushchair 1 stably erects in a folded configuration.In addition, when being expanded to deployed condition from folded state, when vehicle body frame 2 is in folding midway state, restriction castor turning unit 23 cannot rotate around rotation axis X, and front-wheel 7 keeps not rotating as castor forward.
When being expanded to the operation of deployed condition from folded state, identically with during above-mentioned folding operation, the castor of the front-wheel 7 forbidden under folded state and folding midway state rotates.
In addition, in the present embodiment, the locking end position B of castor locking part 24 and locking position C also can be same position.In this case, also can by the displacement of the bending absorption of bar 27 from the midway location β to lower position γ of forward foot in a step movable member 26.
According to the present embodiment, Pushchair 1 comprises elastomeric element 25, forward foot in a step movable member 26, bar 27; Wherein, described elastomeric element 25 is biased castor locking part 24 from locking position C to releasing position A; Arrange described forward foot in a step movable member 26 to conjugate to the forward foot in a step 6; Described bar 27 is as the pipe link connecting castor locking part 24 and forward foot in a step movable member 26.Forward foot in a step movable member 26 and bar 27 become the action component that castor locking part 24 is conjugated.One end of action component connects castor locking part 24, and the other end of action component is arranged at vehicle body frame 2 as forward foot in a step movable member 26.And, abutting part 28 is by abutting the forward foot in a step movable member 26 as the other end of action component, the bias force upwards of opposing elastomeric element 25 makes castor locking part 24 be positioned at locking position C, wherein, described abutting part 28 is metamorphosis parts of the vehicle body frame 2 of metamorphosis from the deployed condition of Pushchair 1 to folded state.Thus, front-wheel 7 is allowed to rotate as castor under the deployed condition shown in Fig. 1 and Fig. 4, is prohibited to rotate as castor under the folded state shown in Fig. 3 and Fig. 6.Therefore, in Pushchair 1 in a folded configuration, front-wheel 7 can stably rotate, and front-wheel 7 and trailing wheel 9 can positively ground connection the Pushchair 1 becoming folded state is stably erected.In addition, in a folded configuration, as castor front-wheel 7 towards with trailing wheel 9 towards consistent forward, comparatively attractive in appearance.
