BACKPACK/BAG/HANDBAG WITH A CHAIR/BACKREST

Description

TECHNICAL FIELD OF THE INVENTION

The actual invention refers to the combination of a bag/backpack and a seat in one object. It has the characteristics of a bag/backpack, which can be articulated into a chair/backrest.

PREVIOUS TECHNIQUE

There are many inventions on the market aimed at the outdoor leisure segment: portable and folding chairs with carrying straps, and an extensive range of backpacks, but none integrates the function of the two objects in only one object.

The following patents documents were identified as being the closest to this Invention:

• • (D1) U.S. Pat. No. 4,530,451—describes a storage device and seat, which is made up of two sections that articulate together. The device can be turned into a chair by previously removing the storage section. D1 differs from the presented invention because the present invention incorporates in a single object the backpack and chair functions simultaneously, hence it does not lose storage functions when converted into a chair.
  • (D2) US 20002023937—describes a backpack with a seat as one piece. It is only adjustable in three positions: transport, sitting and reclining. D2 differs from the present invention since it is adjustable in different fixed angles.

Besides the advantage of joining two objects in one (bag+chair) these retain their active functions simultaneously, in other words, the invention can be an assembled chair/seat and maintain the rucksack/bag function simultaneously. Thus, the present invention does not losses its storage functions when converted into a chair, keeping the area reserved for storage. Also the seat/backrest can be adjustable in different angles, and it is also easy to transport as a backpack or bag.

DESCRIPTION OF THE INVENTION

The present invention combines in one object a bag/backpack and a seat. This combination is achieved by the creation of two parts/planes in the back part of the storage area of the bag/backpack (2) therefore structuring the seat.

The back part of the storage area of the bag/backpack (2) has two pockets (10) e (11) which contains two quadrilateral frames (9) responsible for structuring the seat while defining two planes, responsible for structure the backrest:

• • Integrated bag plane (3) of the rucksack; and
  • backrest plane (7).

The two planes (3) and (7) are joined at the top, creating an axis of rotation (5) allowing these to have adjustable angles. It contains an adjustable ribbon (4) which limits the maximum angle. The cushion seat (8) is attached to the inferior plane of the backrest (7).

The invention can be carried on the shoulder or on the back, it includes a shoulder strap (1) and backpack shoulder straps (6).

Also, when the invention is not being used as a chair/backrest the seat cushion is folded in between planes (3) and (7), reinforcing the lumbar support. The cushion seat (8) is united at the bottom of backrest plane (7), when closed between the planes (3) and (7) serves as a reinforced lumbar support.

When functioning as a chair/backrest, the cushion seat (8) is rotated to a horizontal position and the two planes move to an oblique angle, becoming a seat.

The rear area storage (2) of the backpack/bag contains two pouches, one in the back of backpack/bag (11) and the other on the backrest (10) joined only at the top, creating an axis of rotation (5).

In these two pouches are inserted two frames (9) structuring the planes (3) and (7) and shaping the backrest and the backpack; the plane that integrates the back of the backpack (3) and the plane to serving as a backrest (7).

The frames (9) are made from tubular aluminum and have a quadrilateral shape.
