Description

Baby carriage

Object of the invention

The present invention relates to a cart for babies, of the foldable type and that presents in its previous part a transverse bridge bearing a pair of wheels self-orientating

Background of the invention

There is currently a wide variety of baby carriages Much of these carts allow their folded so that you can see the volume noticeably reduced that occupies, being useful this property to facilitate its transport and storage when not in use.

These carts comprise, in a constitution preferred, a folding chassis that in its previous part is extended by connecting bars with a cross bridge, being at both ends of this cross bridge some self-steering wheels, but this configuration presents a problem considerable when folding the cart, since the bridge and the front wheels are not foldable, and considerably limit the volume reduction of the cart assembly in the position of creased.

Description of the invention

The baby carriage, object of this invention, it presents some technical peculiarities, destined to allow some better folding conditions to reduce its size while maintaining optimal stability in conditions of use.

Thus, the cross bridge is attached to the chassis bars by means of a joint, which defines an axis transverse for the rotation of said transverse bridge between a folded position and an unfolded position. The cross bridge It has at least some first coupling means and a few seconds coupling means, angularly offset for blocking said transverse bridge in the folded position and in the position of deployment by means of blocking means arranged in the chassis.

Thus, the cart can, in a first position, arrange the self-oriented wheels extended towards the front of the car, in a deployed or use position, and in a second position, cross bridge and self-orientating wheels remain retracted towards the bottom of the folding chassis. Depending of the angle existing by the first and second means of hitching, it is possible that the retraction of the transverse bridge and the Wheels are larger or smaller.

The first and second hooking means they are made up of opposing hooks defined in the minus one piece fixed to the transverse bridge and that rotates in solidarity with said transverse bridge.

The means of blocking the transverse bridge in the folded and unfolded positions include:

- a substantially parallel fixing bar to the transverse axis of rotation of the transverse bridge and mounted on the chassis bars with the possibility of displacement longitudinal between an operative, retention position of the first or second transverse bridge hitch means, and an inoperative position of release of said first and second means of coupling of the cross bridge and,

- elastic means that act on the fixing bar and tend to keep it in position
retention operation.

In a preferred embodiment it is provided that The elastic means are arranged inside the chassis bars Thus, the fixing bar (4) is located transversely mounted and with the possibility of displacement longitudinal in collision holes defined in the bars of the chassis.

The opposite ends of the fixing bar protrude laterally from the chassis bars forming two triggers for manual operation to the inoperative position for releasing the coupling means of the cross bridge.

Thus the user to change the position of the cross bridge in both folding and unfolding, only you have to push these outer ends of the bar towards the release position of the corresponding coupling means, enabling the free rotation of the mentioned transverse bridge. For him blocking in one of the two stable positions of the bridge is only it is necessary to lock the corresponding coupling means on the fixing bar, firming automatically.

The hooks are arranged between the bars of the chassis for coupling with the fixing bar. Of this form avoids risks that the user or user receives pinching or stepping on the fingers when handling the triggers of the fixing bar ends, arranged on the outer sides of said chassis bars.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, for illustrative purposes and not limiting, the following has been represented:

- Figure 1 shows a perspective view of the cart.

- Figure 2 shows a profile detail of the trolley with the extended transverse bridge in use position.

- Figure 3 shows the detail of the figure anterior with the transverse bridge collected for folding the trolley.

- Figure 4 shows an elevation detail of the trolley with the extended transverse bridge in use position.

- Figure 5 shows the detail of the figure anterior with the transverse bridge collected for folding the trolley.

Preferred Embodiment of the Invention

As can be seen in the figures referenced the cart consists of a chassis (1) folding that has connecting bars (11) in its part anterior in which a transverse bridge (2) is coupled by a joint (21) with an axis of horizontal transverse rotation, being at both lateral ends of said bridge transverse (2) front self-orientating wheels (3a), presenting the chassis (1) folding another pair of wheels (3b) in its back.

The cross bridge (2) presents in its part later means of hooks, configured by two pairs of hooks (22, 23) arranged at a certain angle to define two extreme folding positions of said transverse bridge (2) when alternately coupled with blocking means configured by a fixing bar (4), arranged transversely on the pair of bars (11) of the chassis (1), being an extended position of the transverse bridge (2) capable for the rolled use of the cart, with said transverse bridge (2) extended towards the front and with the self-orientating wheels (3a) in lower placement, while the other retracted position, fixed stably the cross bridge (2) below the chassis (1)  approximately with self-orientating wheels (3a) collected from substantially horizontal shape to reduce the space occupied.

The fixing bar (4) is arranged transversely through colossal holes (12) arranged on both parallel connecting bars (11), the two ends remaining of said fixing bar (4) projections on both outer sides of the bars (11) of the chassis (1) to configure triggers (41) of manipulation by the user. This bar of transverse fixation (4) is forced by elastic elements (42), in this case some springs, arranged inside each bar (11) of the chassis (1), and tensioned from rivets (13) upper that define the stable position of the fixing bar (4) in the collision holes (12) in its upper part.

The hooks (22, 23) arranged in two pairs, they are set transversely parallel, and located in the space between the tie rods (11) to avoid pinching and accidents with the user's hand when operating the triggers (41).

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
