Description

Front backpack

Object of the invention

The present invention, as expressed in the statement of this specification, refers to a front backpack, whose essential purpose is that the backpack is brought into contact with the thorax and abdomen; that is, with the anterior or frontal part of the body. It has been conceived to transport school supplies, although it can obviously be used in any other circumstance in which similar benefits are required. It presents the peculiarity that the receptacle is carried in front and not on the back, thus avoiding ailments in the spine when transporting the weight with the body upright and in a compensated way.

The backpack is specially designed for school and / or sports use, although it can be applied to other necessities. It could be used, for example, as a backpack for the transport of correspondence, or as a shopping bag, women's bag, etc. Given its characteristics of being transported in the anterior part of the body, it allows the introduction and removal of objects without the need to remove and put on the backpack. It can also be used by women who would thus avoid the well-known bag tugs they suffer. Taking the bag-backpack in front prevents theft that occurs in areas crowded by the well-known pickpockets, who take advantage of the lack of attention or the lack of attention of those affected to open the bag or backpack and steal their belongings. In addition, the weight is transported in an optimal body posture for the back. Background of the invention

Children have to carry a heavy load to school, since from the first courses they carry several books, notebooks and all kinds of school supplies; producing ailments and / or injuries of the spine in many cases in the medium or long term. With conventional backpacks, numerous muscular tensions appear at the level of the back and shoulders. The classic handles of a backpack do not allow to compensate the imbalance of the load backward. This brings with it that the conventional backpacks, although they satisfactorily fulfill the function for which they have been provided, as a material container medium, present in return the problem of forcing users to adopt a body position of pronounced forward inclination, to balance conveniently the weight, which together with its phase of body development, brings about that growth occurs in irregular conditions.

Trying to obviate this problem, the use of car-backpacks has been used, of the type used in the purchase, not being necessary more than a dragging maneuver that is not very difficult.

However, this solution cannot be considered as definitive due to the fact that when the backpack is transported, the load is distributed unevenly unbalancing the spine, since only one arm is used for its drag. Description of the invention

The backpack that the invention proposes has been specially designed and structured to definitively solve the problem previously exposed.

Among the different types of backpacks that are known in the market, the present model has perfected the conventional backpacks and also those that have wheels for dragging, since it can be carried with the column and neck fully erect and without need to carry a backpack in the form of a cart that children or teenagers just don't like. The new front backpack ensures greater comfort, with an optimization of the load distribution. It is also much more practical and safe since it is carried forward, facilitating its use and always keeping it in sight.

Front backpack to be transported attached to the stomach, abdomen, chest and chest of the user; that is, in the front part of the body. It has a padded belt with a lumbar longitudinal adjustment that fastens, with a built-in buckle closure with trident or adhesive type "sailboat", in contact with the lumbar vertebrae, distributing the weight the belt on the hips. In addition, the present backpack equipped with padded bands will lift the shoulders and back of the user Ia, equipped with tensioners for better body adjustment and located at a safe distance from the user's neck to avoid discomfort. On the shoulder area the handles move away from the neck making an outward curve, then close again and approach the column once they are placed on the back at the height of the dorsal vertebrae, thanks to another closure that joins both handles and prevents opening. In the present model there is an important difference to conventional backpacks, since the tensioners of the handles are tensioned from the upper front part, at approximately chest height; so that, to get Ia backpack, only spend an arm on one side and by Io same with the other, and then closing linking clasping the handles and subsequently closing the belt built is achieved easily put.

The front backpack has been provided with a padded reinforcement on its rear face of adaptation to the front part of the user's body, thus preventing any transported object from disturbing the user in his movements. In the event that the backpack is intended to carry light weights, such as those that women can carry in their bags, it will be manufactured without the lumbar longitudinal adjustment padded belt and only with the handles, the closure that joins the handles to the height of the dorsal vertebrae and the corresponding tensioners of the handles. It comprises a body of flexible material, such as a fabric, plasticized fabric or fabric reinforced plastic, including natural materials such as leather. Description of the drawings

To complement the description that is going to be made and to assist a better understanding of the features of the invention is to perform a detailed description based on a set of drawings accompanying this specification, forming part member thereof, and where the following has been represented by way of illustration and not limitation:

Figure 1.- It shows an anterior view of the front backpack placed on the thorax and abdomen invention. Figure 2.- Shows a rear view of the front backpack and its position on the user's back. Preferred embodiment of the invention

In view of these figures it can be seen how the backpack that is recommended configures a receptacle (1) practicable through a zipper or similar, of dimensions and design appropriate to the material to be transported, which may or may not be provided with front auxiliary compartments ( 3) and / or lateral, of a top support handle (4) and a padded reinforcement on its back, which is in contact with the user's chest and abdomen. It has padded handles (5) of support for the shoulders and back of the user of considerable width, which at a later level pass over the shoulder blades and approach a handle towards the other, then lower in parallel near the spine, until separating again at the level of the lumbar vertebrae and go back to the anterior area, near the abdomen. The handles (5) and the receptacle (1), in the upper frontal area, are located at a reasonable distance from the user's neck to avoid discomfort; In addition, said handles are provided with tensioners (6) for better body adaptation in the frontal part, which are placed above the chest, approximately, facilitating their adjustment without removing the backpack.

In addition, the aforementioned handles (5) are joined at the back by means of a buckle closure (7) incorporated with a trident, preferably, which in turn has a longitudinal tensioner for the best body adaptation to the user's size and to prevent the handles open, thus distributing the weight on the central axis of the spine.

It only remains to point out finally, that the front backpack has a lumbar longitudinal adjustment padded belt (2), with built-in sailboat or similar adhesive closure or built-in buckle closure with trident, which is fastened at the back. Said belt (2) may or may not be part of the invention, depending on the size and the load to be transported. It may be the case that, for a small backpack, purse ... is manufactured without that belt, because only with the handles and closing incorporated in the rear part can be transported properly, light weights.

It is not considered necessary to make this description more extensive so that any expert in the field understands the scope of the invention and the advantages derived therefrom.

The materials, shape, size and arrangement of the elements will be susceptible of variation as long as this does not imply an alteration in the essentiality of the invention.

The terms in which this report has been written must always be taken in a broad and non-limiting sense.

Described sufficiently the nature of the invention, it is expressly stated that any modification of detail that is introduced in it will be included within this protection as long as it does not alter or modify
