DESCRIPTION:
BRIEF SUMMARY
The invention relates to a pram, comprising a folding frame provided with wheels and a carrying element connectable to the frame for carrying the child to be transported, wherein the frame comprises a substantially horizontally extending undercarriage and a pushing element.
Such child carriages are generally known. They are provided with a frame which, in addition to the undercarriage, has a part with a cross-shaped structure to which the pushing element is connected, and on which cross-shaped structure the carrying element for the child can be placed. To enable storage of the perambulator in the smallest possible space or to enable it to be taken along in for instance the boot of a car, such a perambulator is collapsible. This generally takes place by removing the carrying element and by folding up the part of the frame with the cross-shaped structure by means of tilting the pushing element. The frame can hereby be folded to a height which is usually slightly smaller than the height of the wheels. Furthermore, the wheels are in many cases also detachable from the frame.
Such a perambulator of the prior art comprises a large number of parts, whereby production is expensive and the frame is relatively heavy.
The object of the present invention is to provide a perambulator which is lighter and whereof the number of parts is smaller.
The invention moreover has for its object to provide a perambulator which, because of its simple structure, has a more attractive appearance than the perambulators of the prior art.
This object is achieved by a perambulator wherein the pushing element extends as a rigid unit above and as far as the undercarriage and is hingedly connected to the undercarriage and wherein the carrying element is connectable to the pushing element.
As a result of these steps, because the cross-shaped part of the frame of the prior art perambulators is omitted, a perambulator is obtained with a much smaller number of components. A perambulator is furthermore obtained of which the appearance is largely determined by the structure of the frame, which is generally seen in a positive light.
Because the pushing element is connected hingedly to the undercarriage the perambulator according to the invention is also foldable.
It is further noted that while perambulators are known in the form of so-called "buggies", which likewise have two rods extending from the front of the carriage obliquely rearward to the handles, a very large number of other rods is moreover still present in these perambulators of the prior art, so that these perambulators have many components and, if they are to be constructed sufficiently robustly, they are comparatively heavy or must be manufactured from costly materials.
According to a preferred embodiment the pushing element of the perambulator is provided with two rods, each connected hingedly to the undercarriage, and with a substantially U-shaped push rod connected thereto for sliding in longitudinal direction, wherein the push rod is lockable with the rods in at least one position.
The present invention will be elucidated hereinbelow with reference to the annexed drawings, in which:
FIG. 1 shows a perspective view of a perambulator according to the present invention;
FIG. 2 shows a perspective view of the perambulator of FIG. 1 in folded situation;
FIG. 3 is a sectional view of one of the two hinge constructions forming part of the perambulator according to the invention; and
FIG. 4 is an exploded view of a detail construction of the perambulator according to the present invention.
Shown in FIG. 1 is a perambulator 1 formed by an undercarriage 2 and a pushing element 3 hingedly connected to the undercarriage 2. Further fixed to pushing element 3 is a sub-frame 4 which is adapted to fix a carrycot 5 or a child seat 6.
The undercarriage 2 is formed by a U-shaped curved tube 7 onto which are fixed shaft stumps 8, on each of which wheels 9 can be rotatably mounted. A wire mesh basket 10 is arranged inside the U-shaped curved tube 7.
Fixed on the frame close to both rear wheels is a
