A Foldable Pushchair For Babies JANE, S.A. A foldable pushchair for babies

FIELD OF THE INVENTION

This invention relates to a foldable pushchair for babies.

BACKGROUND OF THE INVENTION

Some models of foldable pushchairs for babies have been already known for years which comprise only three wheels, i.e. two back ones and a central front one being in some cases a castoring wheel.

SUMMARY OF THE INVENTION

It is the object of this invention to improve the construction of this type of pushchairs for babies as regards their forward lower portion to which the castoring wheel is fitted.

These improvements consist in the provision in the above-mentioned region of the pushchair of a pin-jointed footrest in its turn providing the support for the front wheel, said footrest being apt to adopt an active position and a folded position allowing to obtain a compactly folded arrangement of the pushchair.

Also characteristic of this pushchair is the presence of means allowing to lock and unlock the castoring support of the front wheel, and the arrangement of a cable-actuated braking device allowing to brake said wheel.

The active position of the footrest is locked through means being incorporated in it and gripping a plate being fixed to the lower portion of the front legs.

These and other characteristics will be best made apparent by the following detailed description whose understanding will be made easier by the accompanying two sheets of drawings showing a practical embodiment cited only by way of example not limiting the scope of the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS

In the drawings:

Figs. 1 and 2 illustrate in a perspective view the forward lower portion of the pushchair with the footrest in its position when in use and in its folded position, respectively;

Fig. 3 represents in a perspective view the construction of the footrest; and

Fig. 4 shows in a side elevation the footrest with the· locking means allowing to lock its pin-jointed connection and with the locking means allowing to lock the castoring wheel support.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

According to the drawings the pushchair for babies comprises a front wheel (1) being provided with a pneumatic tire (2) and fitted to the lower portion of the converging front legs (3) and (4) by means of a footrest (5) .

This footrest (5) is formed by a metallic one-piece member in its rearward portion forming two recesses (6) and (7), the lower ends of the front legs (3) and (4) being fitted to said recesses by means of a cross-pin (8) thus providing a pin-jointed connection for said footrest. The footrest (5) at its forward portion has an extension (9) being vertically bored thus forming the cylindrical passage (10) (Fig. 3) allowing to fit the supporting pin (11) carrying the fork (12) to which the wheel (1) is fitted.

The footrest (5) comprises means being apt to lock it in its position when in use, said means consisting in a tightening device being formed by a bolt (13) whose head (14) is pin-jointed on a cross-pin (15) (Fig. 4). extending through holes (16) being provided in a rearward longitudinal protuberance (17) of the footrest (5), said protuberance having an end notch (18). A cylindrical nut 5 (19) is fitted to said bolt an d serves as the pin of a control handle (20) with cam (21) , a spring (22) and washers (23) and (24) (Fig. 4) bolt. being fitted around said In the locked position of the footrest (5) the bolt 10 (13) fits into an upper notch (25) being provided in a plate (26) being fixed to the ends of the legs (3) and (4). rearward portion of the

The castoring of the supporting pin (11) can be locked by means of a lock (27) having two axial positions 15 and being provided with an outer control knob (28) and an: inner pin (29) which in the locked position fits into a hole (30) of said supporting pin (11) (Fig. 4).

This supporting pin (11) is fitted to the extension (9) of the footrest with the aid of bearings (31) and 20 (32), said pin being secured by means of a nut being guarded by a cap (33).

The front wheel (1) is provided with disc-braking means (34) being actuated by means of a cable (35).

The invention can within its essentiality be put 25 into practice in other embodiments differing only in detail from the one having been described above only by way of example, said other, embodiments also falling within the scope of the protection being claimed. , crrixan rwzn arn pnow pnszn irn nr “|»ob ,Ρ’ηη ηχΰ- πώοβπβ mzrna π^πιώώ np’ioz .zruwan ms rnp’nn pmi1? oxnm □ιηπη Pi? _____88°4003 21 J' ·aoi 112JS34Q200 .(moiB nzrnn) cras&'an nwa
