[0001] The present invention refers to a baby-walker with overturning prevention means.
[0002] It is known that baby-walkers are generally made by using a base frame having a closed
structure and which supports a child's chair.
[0003] The frame is mounted on a plurality of casters allowing the child to move in all
directions.
[0004] A problem residing in the baby-walkers now used consists in that, in the occurrence
of an impact against an obstacle, it is not rare that the baby-walker overturns, with
grave relevant risks for the child.
[0005] Another problem resides also in the fact that the inescapable bumps of the baby-walker
against furniture, edges and the like, may provoke damages thereto.
[0006] An object of the invention is to solve the above-mentioned problem by providing a
baby-walker having overturning prevention means which, substantially does not allow,
when impacts occur, overturning of the baby-walker, thus preserving the child's safety.
[0007] Within the above-mentioned object, a particular aim of the invention is to provide
a baby-walker which allows to dampen the impacts against objects or the like, avoiding
in this way damages thereto.
[0008] It is yet another aim of the present invention to provide a baby-walker which, for
its peculiar constructive features, is adapted to assure the highest reliability and
safety in use.
[0009] Last but not least, it is an aim of the present invention to provide a baby-walker
which is easily obtainable starting from elements and materials commonly available
on the market, and furthermore, which is competitive from a merely economic point
of view.
[0010] The above-mentioned object, as well as the mentioned aims and others which will better
appear hereinafter, are achieved by a baby-walker with overturning prevention means,
according to the present invention, comprising a base frame mounted on casters and
connected to a child's chair, characterized in that it comprises, at least in a perimetric
portion of said frame, elastically yielding means for absorbing kinetic energy in
case of impact.
[0011] Further features and advantages will better appear from the detailed description
of a baby-walker with overturning prevention means, illustrated only by way of non-limitative
example in the accompanying drawings, in which:
figure 1 shows the baby-walker schematically in a perspective view;
figure 2 shows a portion of the frame with, in an exploded view, the elastically yielding
means;
figure 3 is a cross-section along the line III-III of figure 1;
figure 4 is a cross-section along the line III-III of figure 1, with the elastically
yielding means in a compressed position;
figure 5 shows the base frame of the baby-walker as viewed from underneath;
figure 6 is a cross-section along the line VI-VI of figure 3.
[0012] Referring to the above figures, the baby-walker with overturning prevention means,
according to the invention, which is generally designated by the reference numeral
1, comprises a base frame 2 having a closed structure and mounted on a plurality of
casters 3.
[0013] To the frame 2 is connected a child's chair 4 which is jointed through a pair of
lateral cross-pieces 5, of a known type, allowing to adjust the height of the child's
chair 4.
[0014] The peculiarity of the invention resides in the fact that the baby-walker 1 is provided,
at an outer perimetric portion of the frame 2, with elastically yielding means having
the function to absorb, in case of impact, the kinetic energy.
[0015] In a preferred embodiment, such a means is constituted by a bumper 10 which has substantially
a C-shape and is housed in a corresponding slot 11 defined at the front portion of
the frame 2.
[0016] The bumper 10 is provided, at the free ends of its arms 10a, with fork-elements 12
which are inserted astride of the end edge of the slot 11.
[0017] Furthermore, the bumper 10, having a U-configuration in cross-section, is provided
with extraction prevention limit stop elements 15 which are wedge-shaped, so as to
allow their insertion inside the slot 11 and for preventing the accidental extraction
of the bumper 10 from the slot since the ledge portion 15a of the wedge-shaped elements
15 engages the inner edge of the frame 2.
[0018] On the bumper 10 act springs 20 which are butt-inserted in seats 21 defined by the
bumper, and at the other end are coupled in lugs 22 provided on stiffening ribs 23
of the frame.
[0019] The springs 20 take up kinetic energy, in case of impacts, by allowing the bumper
10 to enter back into the frame, thus dampening the impact and preventing the overturning
of the baby-walker, since most of the kinetic energy is used to load the springs.
[0020] The provided arrangement allows to easily take up, at the front part of the frame
2, both sheer frontal and slanting impacts, as the bumper 10 is freely movable inside
the slot 11, thus allowing dampening of impacts from different directions.
[0021] From what has been disclosed above, it is evident that the invention achieves the
aims set, and in particular it is stressed the fact that is provided a baby-walker
with overturning prevention means, which, without modifying the conventional way for
making a baby-walker, substantially increases the safety thereof.
[0022] In practice, the materials employed, as well as the contingent dimensions, may be
any according to the requirements.
[0023] Where technical features mentioned in any claim are followed by reference signs,
those reference signs have been included for the sole purpose of increasing the intelligibility
of the claims and accordingly, such reference signs do not have any limiting effect
on the interpretation of each element identified by way of example by such reference
signs.
