Description

TITOLO: “ALLEGGERITORE E AMMORTIZZATORE DI PESO PER ZAINI E CARTELLE SCOLASTICHE” TITLE: "LIGHTENER AND WEIGHT SHOCK ABSORBER FOR BACKPACKS AND SCHOOL BRIEFCASES"

L’invenzione si riferisce ad una soluzione tecnica da applicare ad uno zaino e/o cartella scolastica che genera un alleggerimento e ammortamento del peso. The invention refers to a technical solution to be applied to a backpack and / or school satchel that generates a lightening and amortization of weight.

E’ noto il problema che riempiendo di libri o di cose varie lo zaino o la cartella scolastica, il peso è supportato dalle sole spalle e costringe, chi lo porta, ad assumere un'errata postura con rischio scoliosi e ad una difficoltosa camminata, specialmente per un fisico in crescita. The problem is known that by filling the backpack or school satchel with books or various things, the weight is supported only by the shoulders and forces the wearer to assume an incorrect posture with risk of scoliosis and a difficult walk, especially for a growing physique.

Lo scopo della presente invenzione e quello di avere uno zaino e/o cartella che eviti questi annosi inconvenienti, proponendo di adottare un sistema d’ammortizzazione e alleggerimento del peso tramite un congegno semplice nella sua struttura ed economico nella sua fabbricazione. The purpose of the present invention is to have a backpack and / or satchel that avoids these long-standing drawbacks, proposing to adopt a system of cushioning and lightening the weight through a device that is simple in its structure and economical in its manufacture.

Questo scopo è raggiunto dalle caratteristiche indicate nella parte caratterizzante della rivendicazione 1. This object is achieved by the characteristics indicated in the characterizing part of claim 1.

I dettagli e la conformazione secondo l’invenzione saranno ulteriormente descritti qui di seguito sulla base di un esempio di realizzazione con riferimento al disegno allegato. The details and the conformation according to the invention will be further described below on the basis of an example of realization with reference to the attached drawing.

L’impiego di due braccetti laterali flessibili 1 Figura 1 a molla e fissati ai lati dello zaino e/o cartella e ad una cintura 3 a livello dei fianchi consente tramite il rilascio e il conseguente allungamento delle bretelle sulle spalle nella parte elastica 2, di alleggerire e ammortizzare il peso, tramite la spinta verso l'alto data dai braccetti laterali 1 flessibili a molla. The use of two flexible side arms 1 Figure 1 with spring and fixed to the sides of the backpack and / or briefcase and to a belt 3 at the level of the hips allows, by releasing and consequently lengthening the shoulder straps in the elastic part 2, to lighten and cushion the weight, by pushing upwards given by the flexible spring-loaded side arms 1.

L’Allegggerimento della pressione di carico sulle spalle si attua tramite il trasferimento di peso sui fianchi e gli arti inferiori e, contemporaneamente, la spinta delle bretelle aN'indietro aiuta a tenere la postura più corretta. The lightening of the load pressure on the shoulders is implemented through the transfer of weight on the hips and lower limbs and, at the same time, the thrust of the shoulder straps backwards helps to maintain the most correct posture.

I braccetti laterali 1 , inoltre, più si abbassano e più allontanano lo zaino e/o cartella dal contatto con la schiena, evitando contraccolpi durante la camminata. L'invenzione risulta indicata per gli e studenti in genere, escursionisti, militari e quanti hanno degli zaini particolarmente pesanti, traendone il vantaggio fin qui descritto. Furthermore, the side arms 1 lower the further the backpack and / or briefcase away from contact with the back, avoiding kickbacks during the walk. The invention is suitable for students in general, hikers, soldiers and those who have particularly heavy backpacks, taking advantage of the advantage described up to now.

Qualora lo zaino e/o la cartella non necessitasse deH'ammortizzatore e dell’alleggeritore di peso, le due estremità laterali della cintura possono essere riposte nelle due tasche laterali 7 tramite spostamento girevole dei braccetti con fissaggio 6. If the backpack and / or briefcase does not require the shock absorber and the weight lightener, the two side ends of the belt can be stored in the two side pockets 7 by rotating the arms with fixing 6.

I braccetti possono essere ricoperti con materiale impermeabilizzato. The arms can be covered with waterproofed material.

Claims

R I V E N D I C A Z I O N I 1) Technical solution that applied to a backpack and / or school satchel gives the possibility to lighten and cushion the weight. The solution consists in applying to the shoulder straps, at shoulder height, an elastic part 2 and an appendix on the shoulder strap 4 which must be closed by means of a button 5, applying to a belt 3, which is separate from the backpack and / or briefcase, two flexible spring arms 1, one for each side, at the height of the hips and fixed to the belt 3, the two arms must be connected on the belt side in a fixed way, rotating from the part fixed to the backpack and / or briefcase 6, this allows the weight to be lightened by the upward thrust given by the arms 1. After wearing the backpack and / or briefcase, fasten the belt 3 and unfasten the appendages of the shoulder strap 4, with these two simple operations you will have activated both the lightening and the amortization of the weight.

2) The side arms 1 can also be made with rigid material rather than spring but must have at the base, connected to the belt, a spring that pushes upwards to activate the lightening and amortization.

3) The position of the arms performs four functions: push upwards given by the fixed point connected to the belt 3 and by the fixing point 6 which must be rotatable on itself; absorbs the weight during the walk because they oscillate with the weight of the backpack and / or satchel through the elastic 2; move the backpack and / or satchel away from the back when they are lowered, under the effect of the weight, because they increase the distance from the fixed point of the belt; finally, the cushioned and lightened weight helps to straighten the shoulders and back, by pulling the elastic 2 the shoulders are slightly forced backwards and, with the lightening device, it allows the spine to stand straight and consenting to a correct posture.
