Description

Pram

The present invention relates to a stroller infantile, which comprises a series of wheels positioned so that They define a triangle.

Background of the invention

The strollers currently used  they comprise a series of wheels that can be placed defining a square or a triangle

The strollers with the wheels forming a square or rectangle with suitable for use in cities and in narrow places, since it occupies a small space and allow great maneuverability

In the case of strollers that comprise a plurality of wheels forming a triangle can also be used on uneven terrain, since at all times the wheels of the three vertices of the triangle are in contact with the ground.

However, these types of strollers have the inconvenience of taking up a lot of space, which is especially important if you have to enter an elevator or a trunk of a small car.

Description of the invention

With the pram of the invention They manage to solve the aforementioned problems, presenting other advantages to be described.

The pram of the present invention it comprises a frame and a plurality of wheels placed from way that define a triangle with a front vertex and two rear vertices, and is characterized by the fact that the wheel or front wheels are swivel around an axle substantially horizontal, so that they are movable between a use position and a folded position, in which said front wheel or wheels fold into said frame.

Thanks to this feature, the stroller Infant in its folded position occupies a very small space, what which allows you to enter any elevator or any trunk of a car.

To facilitate wheel handling or front wheels, the pram of the present invention comprises means for locking and releasing said wheel or wheels front with respect to said frame.

According to a preferred embodiment, said means locking and releasing comprise a hook attachable to said frame associated with a lever.

Preferably, said shaft substantially horizontal around which the front wheel or wheels rotate It is located outside the diameter of said wheel or wheels. This way, in the folded position the wheel or front wheels do not protrude from the frame of the stroller.

Brief description of the drawings

For a better understanding of how much has been exposed Some drawings are accompanied in which, schematically and only to non-limiting example title, a case study of realization.

Description of a preferred embodiment

As can be seen in the figures, the pram, identified in general by reference numeric 1, comprises a frame 2 and a plurality of wheels 3a, 3b In the case of the embodiment shown, said wheels 3a, 3b they are placed defining a triangle formed by two vertices rear and a front vertices.

In this embodiment, the front vertex is formed by two front wheels 3b placed one next to the another and rotating around a substantially vertical axis. However, it should be noted that the front vertex could be formed by a single front wheel 3b.

According to the invention, the front wheels 3b are  rotating around a substantially horizontal axis 4 between a position of use (represented in figures 1 and 2) and a folding position (represented in figure 5).

Said front wheels 3b have associated means for blocking and releasing them with respect to frame 2. Said means, in the embodiment shown, they comprise a hook 5 that attaches to the front part of said frame 2. This hook 5 is associated with a lever 6, which facilitates the coupling and decoupling of it.

Figure 1 shows the children's cart 1 of the present invention in the position of use. If you want to fold the cart 1, first the upper handle 7 bends towards in front, since it is articulated with respect to frame 2 (figures 2 and 3).

Once the handle has been folded upper 7, the decoupling of the hook 5 of the part is performed front of frame 2 through lever 6 (figure 3).

When hook 5 has been released, the wheels front 3b can rotate around said axis substantially horizontal 4, as indicated by the arrow in figure 4.

When this turn is done, the front wheels 3b are placed in the folded position, represented in the figure 5, in whose position they do not protrude from the frame 2. This is due to that the substantially horizontal axis 4 is located outside the diameter of the front wheels 3b.

In this way, the children's car 1 of the This invention occupies a very small space, being able to place in very narrow places, such as the trunk of a small car or elevator.

To place the cart of the present invention 1 again in the use position, the reverse operations to those indicated above must be carried out.
mind.

Although reference has been made to a concrete embodiment of the invention, is evident to an expert in the matter that the stroller described is susceptible to numerous variations and modifications, and that all the details mentioned can be substituted by others technically equivalent, without departing from the scope of protection defined by the attached claims.
