The receiving portion 51 has a U-shaped receiving groove and is rotatable in the left and right direction with respect to the third vertical frame 40.

When the driving means 60 is folded back to the rear of the vehicle body B by lifting the frame portion F about the fixed frame 1, the third vertical frame 40 The support portion 51 is supported by the second vertical frame 20 or the first horizontal frame 30 to prevent the vehicle body B from being rolled over to one side.

Although not shown in the drawing, the second transverse frame 50 and the receiving portion 51 may also be provided in the first vertical frame 10 of the first embodiment.

In the above-described embodiments of the present invention, in the above-described embodiments, the driving force is transmitted to the non-powered vehicle body B itself such as a baby carriage, a wagon, and a baby bicycle, except for the driving wheels 62 of the driving means 60 A motor, a battery, or the like).

The grip portion 11a and the tightening member 24 need to be completely separated from the frame body F and the driving means 60 in the body B and then reassembled again. (F) and the driving means (60) can be attached and detached, but the operation thereof can be troublesome.

Therefore, the present invention introduces the attaching / detaching means (70) for detachably attaching the first vertical frame (10) or the second vertical frame (20) to / from the fixed frame (1).

More specifically, referring to FIG. 5, the second vertical frame 20 will be described as an example.

First, the second vertical frame 20 includes an insertion groove 25 formed at the front end thereof with a lower surface and both left and right surfaces opened,

The detachment means (70)

A detachable member 71 having a pair of elastic pieces 71A which are detachably coupled to the lower opening of the insertion groove 25 and are elastically supported outward at the lower end to form a fitting portion 71S,

A pressing member 72 provided rotatably inward and outward from the outer side of each resilient piece 71A and having a pressing projection 72A at the inner lower end thereof,

One side first coupling end 73a is hinged to the inner side surface of the insertion groove 25 and the other side second coupling end 73b is hinged to the pressing protrusion 72A and both side coupling ends 73a And a torsion spring (73) having a circular twist portion (73c) for generating an elastic force so that the torsion spring (73b)

When the fixing frame 1 is inserted into the fitting portion 71S in a state in which the fitting member 71 is lowered and the fitting portion 71S is opened, the fitting member 71 is inserted into the insertion groove 25 The elastic piece 71A pushes the pressed portion 72B of the pressing member 72 and the pressing projection 72A pivots inward to push the elastic piece 71A inward. 73 are forced by the urging force of the pressing members 72 to complete the mounting of the fixed frame 1. [

The detachable member 71 has a locking protrusion 71B connected to an elastic U piece 71A at its lower end and protruding on both sides at its upper end so as to vertically penetrate the upper side of the insertion groove 25 The engaging projection 71B is engaged with the elevating groove 26 formed and raised and lowered.

The pressing member 72 has a pressing surface 72A having a flat semicircular inner surface and protruding inward at the lower end of the pressing member 72. The pressing member 72 has a swing shaft 72a at the inner center, And is pivoted inward and outward.

The torsion spring 73 has the first coupling end 73a and the second coupling end 73b hinged to the pressing protrusions 72A and the inner surface of the rotating space to form respective coupling ends 73a and 73b, The first and second coupling ends 73a and 73b are disengaged and opened while the circular kink 73c is changed in accordance with the rotation of the pressing member 72. As a result, do.

The torsion spring 73 presses the pressing protrusion 72A outward so that the pressing member 72 moves in one direction (the right pressing member 72 in the figure) The counterclockwise direction), the elastic pieces 71A are widened to both sides, and the fitting portions 71S are widened.

When the stationary frame 1 is inserted into the fitting portion 71S in this state, the releasing member 71 is lifted into the insertion groove 25 with the resilient pieces 71A being brought into contact with the upper end of the pressing member 72 The pressing member 72 is pivoted in the other direction (the clockwise direction with respect to the right pressing member 72) by pushing the pressed portion 72B formed on the pressing member 72 The fixing frame 1 is fitted into the fitting portion 71S, that is, the insertion groove 25, by pressing the elastic piece 71A inward to narrow the fitting portion 71S.

At this time, when the pressing member 72 rotates in the other direction, the respective coupling ends 73a and 73b of the torsion spring 73 are pinched and the position of the circular twisted portion 73c moves inward, When the position of the circularly bent portion 73c is shifted by the position of the circularly bent portion 73c, the respective engagement ends 73a and 73b are opened again to generate an elastic force so as to press the pressing protrusion 72A inward, 71A are forcedly held and the fixed frame 1 is not detached from the fitting portion 71S.

When the second vertical frame 20 needs to be separated from the fixed frame 1, the detachable member 71 is strongly pressed by the pressing hole 26a formed in the upper surface of the elevating groove 26, The urging force of the torsion spring 73 is restored by pushing the urging members 71A with a force exceeding the elastic force of the torsion spring 73 supporting the pressing protrusions 72A on both sides, So that the pressing protrusion 72A is separated from the elastic piece 71A so that the elastic piece 71A is opened so that the fitting part 71S is separated from the elastic piece 71A So that the fixing frame 1 can be separated from the insertion groove 25 by being widened.

The attaching and detaching means 70 firmly maintains the mounting state of the stationary frame 1 to firmly maintain the connection between the body 10 and the frame portion F, (60), and the driving means (60) can be folded.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the present invention is not limited to the above-described embodiments, but various modifications, alterations, and substitutions can be made by those skilled in the art. Should be construed as falling within the scope of protection of the present invention.
