Abstract

Disclosed is a baby game vehicle which comprises an upper tray, a base, a height adjusting mechanism, an inner supporting frame and an outer supporting frame. Further, the inner supporting frame and the outer supporting frame are in sleeve joint with each other telescopically and connected between the upper tray and the base, and a plurality of positioning grooves are disposed inside the inner supporting frame. The height adjusting mechanism consists of a knob, a clutch, a linkage mechanism, fixing blocks and an elastic component, the knob and the clutch are disposed on the outer supporting frame, height can be adjusted by means of the movement positioning of the fixing blocks inside the positioning grooves, the knob is in linkage with the clutch, and the clutch drives the linkage mechanism so as to drive the fixing blocks to be separated from fixing grooves. When the inner supporting frame and the outer supporting frame are in temporarily fixed state, the knob is separated from the clutch to stop the knob from driving the fixing blocks to move directly through the linkage mechanism, thereby preventing the inner supporting frame and the outer supporting frame from sliding relatively when an operator contacts the knob mistakenly, avoiding error operation of the operator or hurting fingers of the operator and further realizing the purpose of safety.

The specific embodiment

The utility model is for the virgin recreation of baby car height adjustable structure, adjusts recreation overall height degree for the operator, uses with the baby child who is fit to differing heights.

Shown in Fig. 1～3, the recreation car 10 convertible three kinds of use sample attitudes in the middle of this example are used for the baby is virgin; Comprise: as the use sample attitude 100 of go-kart, the use sample attitude 200 that is used to play and as the use sample attitude 300 of go-cart.

Described recreation car 10 comprises: coil the supported on both sides frame 4 and a gameboard 5 of 2, one pedestal 3, a pair of scalable adjustment length on one, wherein go up dish 2 have one can be for the seat 21 of operator's dismounting for carrying baby child.

Pedestal 3 includes wheel 31, for moving game car 10.4 on supported on both sides frame is connected between dish 2 and the pedestal 3.Gameboard 5 movably is installed on pedestal 3, gameboard 5 can temporarily occupy due to three positions, comprise and be positioned at pedestal 3 rearward position and form a go-kart kenel 100 (shown in the 1st figure), be positioned at 21 belows, seat, can trample the use sample attitude 200 (as shown in Figure 2) that is used to play of recreation and be positioned at pedestal 3 the place aheads for the virgin foot of baby, then dismantle seat 21 and afterwards form a use sample attitude 300 (as shown in Figure 3) as go-cart.

See also shown in Figure 12ly, wherein the supported on both sides frame 4, are the distances of

dish

2 and 3 of pedestals in the scalable adjustment, to be fit to baby child's use of differing heights.

Refer again to shown in Fig. 4～6, bracing frame 4 is made up of outer support frame 41 and inner support frame 42, and is established the 3rd elastic parts 43 in 42,41 of inside and outside bracing frames, so that integrated support frame 4 has the effect of spring.In the middle of present embodiment, inner support frame 42 is connected with pedestal 3 both sides, and 41 of outer support frames are connected in dish 2 both sides with respect to inner support frame 42 positions, and is flexible by the relative socket of inside and

outside bracing frame

42,41, so that reach the purpose of adjusting height.

Height Adjustment mechanism 6 is to be installed between the inside and

outside bracing frame

42,41, comprises a knob 61, a clutch 62, an interlinked mechanism 63, fixed block 64, first elastic parts 65 and a plurality of locating slot 66; Wherein a plurality of locating slots 66 are equidistantly or the not equidistant inner support frame 42 inner radial linear positions that are distributed in, and clutch 62 includes a limited part 621 and a driving-disc 622, wherein limited part 621 is to be fixedly coupled in outer support frame 41, and include a plurality of limiting grooves 623, then rotating outer support frame 41 inside that are articulated in of driving-disc 622, and make the pillar 611 and its pivot joint that knob 61 extended, and drive driving-discs 622 and rotate by knob 61 post 611 of asking for an advance on one's pay.

Shown in Fig. 7,8,9, knob 61 further comprises a projection 612, projection 612 is to engage with the limiting groove 623 of limited part 621, under normality, device has one first elastic parts 65 between knob 61 and the limited part 621, engage with the limiting groove 623 of limited part 621 so as to the projection 612 that keeps knob 61, knob 61 can't be rotated.

Please be with reference to shown in Figure 10, interlinked mechanism 63 comprises a linkage assemblies 631 and a slide block 632, wherein linkage assemblies 631 1 ends are to be articulated in driving-disc 622, the other end then is connected with slide block 632, slide block 632 further includes the skewed slot 633 of a pair of both sides that are placed in, borrow skewed slot 633 to articulate fixed blocks 64, break away from locating slots 66 so that slide block 632 can drive fixed blocks 64 by skewed slot 633 when moving.See also shown in Figure 11, linkage assemblies 631 is provided with one second elastic parts 634 (or being installed between two fixed blocks 64), borrow second elastic parts 634 when fixed block 64 misalignment locating slots 66, to keep thrust, after contraposition, fixed block 64 is pushed in the locating slot 66, to reach the purpose of automatic engaging location.

Please continue with reference to shown in Figure 11, driving-disc 622 and linkage assemblies 631 articulated sections, be provided with an arc groove 635, make driving-disc 622 when rotation, because of the space of arc groove 635 directly drive link external member 631 move, and the interior idle running in advance of the scope that is this arc groove 635 directly drives interlinked mechanisms 63 by knob 61 via driving-disc 622 to avoid the operator.

Please continue with reference to shown in Figure 10～11, when inside and outside

bracing frame

42,41 during in positioning states, fixed block 64 is to engage with locating slot 66, and the projection 612 of knob 61 is to engage with the limiting groove 623 of limited part 621, can't directly move with the restriction operator via knob 61 operation fixed blocks 64, to avoid faulty operation or false touch, to reach the purpose of safety.

When taking advantage of when height seat of dish 2 in the adjustment of operator's desire, press earlier and press knob 61, make the projection 612 of knob 61 break away from the restriction of limiting grooves 623 and free to rotate, the further turn knob 61 of operator, knob 61 interlock driving-discs 622 are pivoted, to move up via linkage assemblies 631 pulling slide blocks 632, driving fixed blocks 64 by the skewed slot 633 of both sides contracts in laterally mobile each other, and make fixed block 64 break away from locating slot 66, in the releasing,

outer support frame

42,41 mutually positioning states, and then be adjusted to the locating slot 66 of another suitable height, fixed block 64 can relend by second elastic parts, 634 elastic force of linkage assemblies 631 and enter locating slot 66 automatically, so as to reaching the purpose of adjusting height.
