DE2649067A1 - Rucksack with ventilated layer next to wearer's back - is perforated material made of metal, plastics or vegetable material, and has springy texture - Google Patents

Abstract

The ventilated layer consists of perforated plate or stiff mesh material, with spacer pieces behind them. The ventilated layer can be partly or wholly perforated, and have a structure which is corrugated, like waffle sheet metal, buckle plate, or mushroom type plate; or alternatively, can have knobs, angled knobs, or similar structure. The layer may be of foam with large open cells. When of mesh material, the ventilated layer can be of metal or plastic or another sufficiently rigid material. The layer can be of wicker, cane, sisal matting or other similar material. The layer is coated with a layer which is permeable to air and the layer is springy.

Description

backpack

There are preferably 2 types of backpacks in use: 1 with a built-in frame and a tensioned strap, which is attached to the wearer in the area of the lumbar vertebrae, otherwise between +, backpack and back mostly there is a gap; this type was formerly known as the Norwegian backpack.

It has the advantage that you don't sweat on your back.

2 rucksacks that lie flat against the wearer's back, in # the back * are usually wooden sticks or a whole plate incorporated so that the backpack not deformed like a bag or hard objects stowed in the backpack press your back.

Such rucksacks are usually found to be more comfortable to carry and have become more popular again in recent years compared to the species mentioned under 1) However, they have the disadvantage that one sweats easily on the back. This is stirring therefore, that the skin of the back is covered over a large area, almost airtight, especially Backpacks are nowadays made of impermeable material when the invention Backpack, similar to the Norwegian backpack, it is ensured that between the backpack and back there is a space through which an exchange of air is possible Otherwise it corresponds to type 2, i.e. also in terms of weight distribution: the overturning moment of the backpack is supported against the whole back and not just against the lumbar spine According to Figure 1, there is a moderately stiff, permeable layer - e.g. a perforated one Plate made of sheet metal, plastic, pressed material or the like., Or a stiff mesh - by means of spacers attached to the back of the backpack. Now air can flow from the sides behind the permeable layer and exchanged through it to the skin This creates a ventilated layer between the backpack and the Back of the wearer.

*) The "back" should be understood to mean the side of the backpack that rests on the back of the wearer.

The idea of the invention allows one of variants.

Instead of a perforated plate with spacers, there is the one before defined "ventilated layer" made of perforated corrugated sheet. Also corrugated sheet with Crossing corrugations (nipple or hump sheet) or mushroom sheet according to Figure 3 is suitable, whereby not necessarily sheet metal but any sufficiently strong and stiff material, such as Plastic foil, hard rubber sheet or stiff braid can be shaped accordingly of this type, a considerable exchange of air is achieved even without perforation. (Photo 4) ~ / neh Photo 2 Furthermore, the ventilated layer can consist of wire mesh mat *, foam with coarse open lines made of stiff material (e.g. made of Hert-PVC, but no soft o5, f; jr foam upholstery common material), wicker or beard weave.

Any type of ventilated layer mentioned can be made with permeable Fabric, cotton fabric for example, can be covered, @@@@ not @ i @ @@@@@ ic @@ @@@@@ stoffmda this will destroy the desired effect. Line increase the ventilation efiect is achieved when the ventilated layer is resiliently compressible such that while walking and rocking the rucksack, it keeps squeezing itself together and again This creates a pumping effect, the air is not just natural Convection, but forcibly exchanged. This is achieved by the fact that the ventilated Layer is made wholly or partly of elastic material, e.g. Spring steel, rubber, hard Types of plastic.

glass fiber reinforced synthetic resin.

* What is meant here is not a flat, sieve-like braid, but a thick one Mat, e.g. made of interwoven spirals.
