Description:
SITTING STRUCTURE FOR CHILDREN. APPLICABLE TO A BICYCLE

Description

The present invention refers, in general, to a sitting structure for children, applicable to a bicycle. More particularly, the present invention refers to a sitting structure comprising a child seat and fixable to a bicycle for adults in such a way as to guarantee safety and comfort for the child placed on the child seat and the adult who drives the bicycle.

As is known, when a child has to be carried on a bicycle for adults, it is necessary to use suitable child seats to be fixed to the bicycle itself.

The child seats applicable to the bicycle for adults are usually of two types.

The child seats for rather small children aged about eight months to eighteen months are made according to a first typology and are mounted on the bicycle handlebar so that the child accommodated on the child seat is facing the front part of the bicycle and can, therefore, see forward without any obstacle.

A second typology of child seats, suitable for children over eighteen months old provides for fixing the child seat to the rear part of the bicycle, and precisely to the frame on the crosspiece that goes from the saddle to the central movement system to which the pedals are pivoted.

Even according to this second typology, the child sitting on the child seat is facing the front part of the bicycle but in this case, the child is sitting behind the adult who drives the bicycle so that it is not possible for the child to see forward and this position is not very stimulating for the child who is forced to turn his head sideways to see what is around him and places himself in an uncomfortable position.

In order to avoid said problems, child seats have been conceived to be applied to the rear part of the bicycle in such a way that the entire body of the child is arranged laterally to the bicycle or even arranged toward the rear part of the bicycle.

However, in these cases there may be another problem, namely that the child needs to see the adult who is accompanying him and needs to feel secure and not abandoned.

An object of the invention is to overcome the above-mentioned drawbacks and others by making a sitting structure for children, fixable to a bicycle for adults, ensuring an excellent view for the child accommodated on the seat.

Another object of the invention is to provide a sitting structure for children, fixable to bicycles for adults, meeting the needs of the child, changing over time, in terms of safety and comfort.

A further object of the invention is to provide a sitting structure for children, fixable to bicycles for adults, ensuring a good comfort even to the adult who drives the bicycle to which the sitting structure in question is fixed.

The above-mentioned objects and still others are reached according to the invention through a sitting structure for children, applicable to a bicycle for adults and comprising a rear hub and a crosspiece connecting the hub to the bicycle saddle.

The sitting structure according to the invention comprises a frame which is fixed in a removable way to the rear hub, and a child seat which is fixed rigidly to the frame and faces the rear of the bicycle.

The said sitting structure according to the invention is characterized by the fact that the frame comprises a base structure to which an arm is pivoted by means of a first hinge, a clamping system being fixed to the free end of the arm for a removable coupling of the arm to the crosspiece of the bicycle.

Through this configuration, in particular through the possible rotation of the arm with respect to the base structure of the frame, the sitting structure according to the invention can be connected to any bicycles of different models and sizes.

Besides, the sitting structure according to the invention allows to have the child seat facing the back of the bicycle so as to offer full view to the child.

Advantageously, a second hinge may be fixed to the base structure at the opposite end with respect to the first hinge and the arm may be removable from the first hinge so as to be fixed to the second hinge.

In this way, the sitting structure can be coupled to the bicycle so that the child seat can be turned, alternately, towards the rear part or the front part of the bicycle.

In order to allow the sitting structure to be removably fixed to the bicycle, a bracket may be fixed below the base structure and develops perpendicularly to the base structure and may be coupled to the hub.

In order to reinforce the frame, the frame itself may comprise a bar, the bar ends being welded to the bracket and to the base structure, respectively.

Advantageously, in order to ensure a comfortable sitting of the child and the adult driving the bicycle, the child seat may comprise a backrest including a first lower cavity on which the child's back can rest, and a second upper cavity where the back of the adult driving the bicycle can rest.

In order to ensure the safety of the child, the child seat may comprise supports for the child's feet.

In addition, the child seat may comprise side walls preventing the child's legs from inserting dangerously between the spokes of the rear wheel of the bicycle.

Further features and details of the invention will be better understood from the following specification which is provided by way of a non-restricting example as well as from the annexed drawing, wherein:

Figure 1 is a schematic side view of a sitting structure for children, fixed to a bicycle, according to a first embodiment of the invention;

Figure 2 is a schematic side view of a sitting structure, according to a second embodiment of the invention.

With reference to the annexed Figure 1 , reference number 10 denotes a sitting structure with a child seat fixed to a bicycle B for adults.

The sitting structure 10 includes a frame 12 and a child seat 14, fixed to the frame 12 rigidly.

In particular, the frame 12 includes a base structure 16 to which the child seat 14 is fixed and is facing the back of the bicycle, as it appears from Figure 1.

A bracket 18 is fixed below the base structure 16 and develops perpendicularly to the base structure 16.

Besides, the bracket 18 has a lower end which is fixed by means of a connection device to the frame of the bicycle B in correspondence of the rear hub M.

The coupling of the bracket 18 to the base structure 16 is ensured also by an oblique bar 20, the ends of the bar being welded to the bracket 18 and the base structure 16, respectively.

A first hinge 22 is fixed to the front end of the base structure 16 and connects the base structure to an arm 24 so that it is possible to vary the inclination of it. The same arm 24 is fixed in a removable way to the crosspiece T of the bicycle B. The crosspiece T extends from the rear hub M to the saddle. The releasable fixing of the arm 24 to the crosspiece T is obtained by means of a clamping system 26.

A second hinge 28 is fixed to the rear end of the base structure 16, the arm

24 being fixable, in case, to said second hinge.

In fact, as shown in Figure 1 , the child sitting on the child seat 14 is facing the rear part of the bicycle and, therefore, can see all around without having any obstacle in front of him.

In case the child needs to perceive the presence of the adult who is driving the bicycle, the sitting structure 10 can be removed from the bicycle B by releasing the connecting device of the bracket 18 from the hub M and releasing the clamping system 26 from the crosspiece T of the bicycle B.

Once the arm 24 has been removed from the first hinge 22, the arm 24 is fixed to the second hinge 28 and then, the entire sitting structure 10 is rotated 180 degrees and is mounted on the bicycle B by means of the connecting device and the clamping system 26.

In this way, the child seat 14 is now turned toward the front part of the bicycle and the child is in contact, even visually, with the adult who is driving the bicycle B.

Besides, the possibility of rotating the arm 24 with respect to the base structure 16 allows to fix the sitting structure 10 to every bicycle for adults, regardless of the size of the bicycle B and the inclination of the crosspiece T.

According to a variant of the invention as shown in Figure 2, a sitting structure 110 for children, fixable to a bicycle for adults, comprises a child seat 114, fixed to a frame 112, which corresponds to the frame 12 previously described for the sitting structure 10, and includes corresponding elements denoted by the same reference numbers increased by a hundred.

However, unlike that, in addition to feet supports 130 and side walls 132 preventing the legs of the child from inserting dangerously among the spokes of the rear wheel of the bicycle, the child seat 114 comprises also a particularly shaped back.

In fact, the back of the child seat 114 includes a first lower cavity 134 on which the back of the child can comfortably rest, as well as a second upper cavity 136 on which the back of the adult, who drives the bicycle on which the sitting structure 110 is fixed, can rest.

A technician of this sector can make changes or variants that are to be considered as included in the scope of protection of the present invention.

For example, the bracket for fixing the base structure to the wheel hub of the bicycle can be double so as to form a kind of fork astride of the rear wheel.

Besides, the arm that connects the base structure 16 to the crosspiece T of the bicycle B can be telescopic.
