The specific embodiment

With reference to described accompanying drawing, make children can learn device integral body on foot, and comprise that the bottom 2 that has two

arms

3 and 4, each arm are installed on the front-wheel 5 and trailing wheel 6 that is placed on the surperficial P by 1 mark.Trailing wheel 6 can be fix or pivoted, in one situation of back, they comprise button-type locking member 10 commonly used with the locking respective wheel around the rotation of its axis.

Arm

3 and 4 hinged (at 9 places) is to the side of main body 11, and the top 7 of main body is provided with handle 12.Main body 11 can be folded between the arm 3 and 4 (Figure 10) fully, or can be in different stable inclinations or angular position (for example two) with respect to these arms.The control member 15 that is positioned on each

side

16 and 17 of main body 11 can change the relative position between

arm

3,4 and the described main body.

Handle 12 comprises

side arm

20,21, and side arm hinged (at 23 places) is to the parts 7 of main body 11 and support the handle of arranging transverse to described arm 24, and handle 24 is configured as aptly is convenient to children's grasping.Handle can stably be in a plurality of diverse locations (for example three) with respect to main body 11 inclinations.Make handle 12 and main body 11 make device of the present utility model can be in diverse location around the equipment that arm 3 and 4 (thus with respect to surperficial P) is inclined to diverse location, that is to say, make handle can be in the differing heights of surperficial P top, so that along with the different phase of the child growth of operative installations 1, make children be in correct posture when learning to walk walking about by grasping member and between

arm

3 and 4 to move.

With reference to figure 3 and 4, these figure demonstrate and

arm

20 and 21 are connected to mechanism that at least one articulated joint 23 of main body 11 links to be used to change described gradient.What show among the figure for the sake of simplicity, is that described mechanism and arm 20 link.This mechanism comprises makes the action button 30 of arm around main body 11 rotations; Button 30 has the substantially shell 31 of cup-shaped, and this shell cooperates with the compression spring 32 that is inserted between described shell and the fuel plate 33, and fuel plate has two and connects together and isolated

circular portion

35 and 36 by interconnecting member 37.These

parts

35,36 and parts 37 make fuel plate 33 be connected to

arm

20 and 21 both they are moved, and be connected to the top 7 of main body 11, this element and main body are fixed.

More particularly, button 30 has cylindrical annular ridge 41 from inner surface 40 to projecting inward shell 31, and cylindrical annular ridge receives the cylindrical pin 42 of the respective aperture on the top 7 of the hole 43 passed on

respective arms

20 or 21 and main body 11.This pin is connected with lateral part 45 to form element 46 therewith and is used for arm 20 or 21 (whole thus handle 12 is even described mechanism is only fixed with an arm) is locked in the position with respect to parts 7 inclinations of main body 11.Part 45 has lug boss, spicule or similar protuberance 48, to cooperate with the base 50 of the circular portion 35 that is arranged on the element 33 that is in interval location in the chamber 49 of parts 7; Base 50 limits the different angular position of the handle 12 on the main body 11.

The compression spring 32 that is arranged between pin 42 and the ridge 41 is placed on the circular portion 36 of element 33.Preferably, this latter has hollow component 52 to receive spring 32.In the chamber 54 of

respective arms

20 and 21, part 36 rest arm originally on one's body with the edge of the parts 7 of main body 11 on.Part 35 also rests on this edge, but in the chamber 49 of those parts.When the shell 31 of button 30 by towards

respective arms

20 or 21 extruding the time, the lateral part 45 of element 46 can be moved chamber 49 in, away from the gradient of part 36 with change handle 12.The pressure of antagonistic spring 32 withdraws from part 45 from the circular portion 35 of fuel plate 43, its protuberance 48 leaves base 50 thus, makes handle change the spatial attitude of handle 24 thus around parts 7 rotations of main body 11.When discharging shell 31, rotation continues, and becomes up to lug boss till the place ahead of other bases 50 (corresponding to the different gradients of handle 24) that are positioned at along laying-out curve; In this case, by acting on shell, spring 32 promotes these lug bosses and enters the rotation of described base with lock handle in the position that is reached.

Fig. 5 illustrates the mechanism that is used to change main body 11 with respect to the gradient of the arm 3 that wheel is installed and 4 to Fig. 8.

This mechanism is inserted in the hollow parts 60 of main body 11, has at least one control member 15 (being shown as in the drawings on the

side

16 and 17 that is positioned at main body 11) in the side of main body.Except that control member 15, described mechanism comprises and the fixing arm 62 of described member that arm 62 is provided with tooth 64 on side 63, and it cooperates as tooth bar and with gear 66.The latter links by commonly used screw 67 and second gear 68, second gear thus with first gear 66 coaxial and reverse with it fixing, thereby cooperate with tooth bar 70, tooth bar 70 and the member or the element 71 that can move in the parts 60 of main body 11 link.

Member 71 is strip (tooth bar 70 is arranged on a side), and its opposed

end

73 and 74 respectively carries protruding pin 75,76.Spring 77 is installed with on the fixed part 78 that is shelved on main body 11 around pin 75, and stops element 71 to move with gear 68 rotations, and this will be described below.One in the pin 76 of element 71 and a plurality of bases 80 cooperates, and base 80 is arranged on and installs on the fixing arch member 81 in 1 bottom 2, and protrudes in the parts 60 (hollow) of main body 11.

Be used to change the gradient of 3,4 of main body 11 and arms and use in the following manner with the aforementioned mechanism that this mode changes the spatial attitude (or height) of handle 12 above surperficial P.In order to obtain this motion, control member 15 is by it is operated towards the inside extruding of the parts 60 of main body 11.This pressure makes corresponding tooth bar 64 towards the internal motion of these parts, causes gear 66 and gear 68 rotations, the motion that makes progress with respect to arch member 81 of element 71 subsequently.The effect of the motion antagonistic spring 77 that should make progress is carried out.Therefore, the pin 76 of element 71 exposes from base 80, and this pin is placed in the base to keep the position that had before reached of main body 11 with respect to arm 3,4.After pin 76 left corresponding base, main body 11 can be positioned at another base 80 tops up to pin 76 directly manually around articulated joint 9 rotations (Fig. 1 arrow F).When being in this position, by means of the thrust that acts on the spring 77 on the element 71, pin 76 stretches into described (new) base 80 with the rotation (and make member 15 turn back to its initial rest position) of locking main body 11 around arm 3.In this position, main body 11 is in new (being different from aforementioned gradient) gradient on surperficial P.

As shown in figure 10, main body 11 can be folding fully towards

arm

3 and 4, reaches the position that is folded in fully between them thus.In addition, each pin 76 is run into corresponding base (being 90) and is made main body 11 can keep stable position between

arm

3 and 4 in Fig. 5 in this position.This can transport device 1 easily in its folding position.

Utility model provides a kind of makes the children of any age or height can learn on foot the device of maintenance correct body position in this learning process simultaneously.This device uses and convenient transportation.

Described optimum embodiment of the present utility model, yet according to appended claim, other embodiment also is possible.
