Description

  The present invention relates to the technical field relating to backpacks, school bags and baggage carried on the back for all sports, hiking, mountaineering, school bag or stroller applications.

  Carrying bags, rucksacks, strollers, etc. imposes comfort requirements for the wearer, particularly for ventilation between the back of the bag or baggage and the wearer's back. The same applies to these components of the shoulder strap or belt type.

  In this case, Applicants have developed a backside support system that includes the possibility of backside ventilation and air blowing that produces a better level of comfort.

Therefore, the first embodiment described in the prior art patent document will be described. The rigid frame is arranged with joined branches that form an inverted V-shape. In order to form an air circulation space, the first branch portion is configured to interact with the bottom portion of the back surface and the rear surface of the gripping waist belt (see, for example, Patent Document 1).
French Patent No. 96/05194 Specification

  This type of arrangement is still impractical and the blowing area is limited to the bottom of the back.

Thereafter, in another prior art patent document, the applicant forms an air passage, and on both sides of the top upper part and the bottom lower part, keeps it upright away from the wearer's back and allows ventilation. Promoted and arranged with a protruding and hollow shape defining a longitudinal central indent from the top to the bottom, with a protruding area, fastening the area at the top portion of the shoulder strap and the bottom portion of the belt A thermoformed back surface was developed (see, for example, Patent Document 2). However, this apparently intriguing solution has certain limitations with respect to application and comfort, despite its light weight and cost. The shape part obtained by thermoforming the back surface is fixed and final, and constitutes a stiffener. These shapes are then optimized for certain people other than others who differ in elongation and anatomical form. For several reasons, protruding areas are dangerous and cause damage. This is why the applicant has not pursued industrial development of the structure.
French Patent No. 98/06704 Specification

Thus, the Applicant has proposed in another prior art patent document a rucksack with a plurality of parallel channels in which the back of the bag is arranged vertically and opens at its own end (eg, patent document). 3). The outside of these channels is covered with a perforated sheet or a net configured to contact the wearer's back. This solution is satisfactory in terms of ventilation, but was still expensive to implement.
French Patent No. 2700252 Specification

  Applicant therefore addresses all constraints through different operations on the line that did not provide a satisfactory solution by industrial scale production for cost, comfort and / or adequate ventilation The research was continued to find an optimized solution.

  The study gives quite reasonable quality prices and comfort levels under all conditions of wider use, regardless of personal condition and personal form, and is extremely relevant to all constraints on use and comfort. Reached a new solution to deal as the foot goes.

  According to the first feature, the structure provides a ventilation function and can be attached to any article worn by a person. Said structure comprising projecting regions constituting stiffeners defining channels for the passage and ventilation of air is at least one made of a flexible material that can be deformed by a mesh placed on its entire surface It is noteworthy in that it consists of a grid. The grid has a plurality of protruding shapes obtained by a molding process that gives shape memory to a plurality of shape portions. Said shape is obtained in the form of a mesh arranged and arranged to define a ventilation channel. In addition, the outer peripheral wall and the upper surface of the shape portion are flexible (that is, easy to bend) and deformable, and ventilation is generated through the entire mesh of the grid.

  In order to establish the subject matter of the present invention, non-limiting aspects are illustrated in the figures.

  In order to more particularly identify the subject matter of the present invention, it has been described herein in a non-limiting manner with respect to the figures in the drawings.

  The present invention applies to a bag back structure, but also applies to, for example, a bag carrying shoulder strap and / or a waist belt disposed on a rucksack. The present invention is illustrated in more detail with respect to the back of the bag.

  Therefore, the first embodiment described in the prior art document will be described. The rigid frame is placed with the combined branches that make up the inverted V-shape. In order to form a space for air circulation, the first branch is configured to interact with the bottom of the back surface and the rear surface of the gripping waist belt.

  According to a first feature, the device for adjusting the back position of a rucksack of the type comprising a rucksack back surface in which a portable harness is arranged on the back surface of the rucksack in a manner that can be adjusted by remote manual control, Established with the help of a remote manual control that allows the position of the back of the rucksack to be adjusted relative to the portable harness in an independent relationship, with two positioning and control means, the dimensions of the back of the rucksack To the user's back and to change the body part that is supported during walking to limit and reduce all possible obstacles, the first means is the back of the rucksack against the harness The second means can lower the backpack back portion with respect to the harness, and the backpack back portion A rucksack configured to accommodate a circulating belt disposed in its central longitudinal plane, the belt being secured to the portable harness by a strand, and either by position adjustment and / or control means, or both The locking mechanism operated by the second control means acts on the circulation belt so that the back surface portion can be displaced relative to the harness, and the circulation belt responds to a desired displacement phase. It is characterized in that it can be fixed or released in position.

  The breathable back structure according to the invention consists of at least one grid (2) thermoformed or heat-compressed made of an extruded polyester type or similar material of a bendable and deformable material. This grid (2), made by a mesh installed over its entire surface, allows air to flow in all directions. This grid is still further created by a plurality of protruding features (2a) obtained during the action and processing of the thermo-compressed or thermoformed shape that gives the overall continuity of the mesh across the entire surface of the grid. These projecting shapes (2a) define the same or different volumes. Moreover, these shapes are the same or different. These are arranged in rows and aligned to form vertical channels (2d) and / or horizontal channels (2e) or other continuous configurations to provide ventilation and prevent collisions These shapes (2a) made on the basis of the grid (2) allow swivel movements in all directions with total ventilation over the “breathable” back structure. The passage and circulation of air through these features, according to a particular advantage of the present invention, the outer peripheral wall (2b) made in these features (2a) and their upper side ( 2c) is easy to bend by itself due to its ability to elastically deform when spot-type pressure occurs on the wearer's back, and the shape of the block (2a) thus created can be deformed as a function of the applied pressure. Made by These shapes (2a) are in the form of a mesh and the ventilation occurs in a fixed manner at all points, so that the overall optimization and portable Because of these deformation systems, these shapes (2a) do not collide, and the shape memory causes the entire assembly to have some elasticity when pressure is subsided, so that these positions Return to.

  This structure may comprise a plurality of grids of the type described above arranged in the same or different protruding features. However, the grids are placed on exactly the same shell and define a similar volume for placement on one and the same shell to form a homogeneous unity. This embodiment in the form of multiple grids may be selected for molding and cost.

  Thus, it will be appreciated that the back assembly according to the present invention applies to people of different anatomical forms without awkwardness, discomfort or damage. The grid or grids in the desired shape and dimensions as a function of the application are secured to the support shell (3) that makes up the back structure and may be by any linkage, adhesive bond, contact and closure means or as described above. The support shell (3) is fixed to the shell by covering and fastening with a fabric boundary (3a) on the outer peripheral boundary. The back structure thus described comprises a carrying harness comprising a portable shoulder strap portion (4) and a waist belt (5) and a hygienic protective cover net (6) separating it from the individual bodies. Can be arranged in a known manner. In this case, the net is either tensioned between the outer peripheral edges of the support shell (3a) or can also be thermoformed or compressed and conforms to the contour of the shape (2a). The material used to make the grid or grids is advantageously a polyester, but any other material and ingredients that perform the functions described above may be used. By virtue of its components according to the present invention, the breathable back structure comprises a wing made at the continuation of the central part at the lateral end, even though this is useful as a function of the application, And a wearer's side part can be surrounded to a slight range.
