Abstract

SEAT WITH SELF ADJUSTABLE PINED SEAT. It consists of a stool (1) formed from a box (2) capable of organizing several independent pins (3), which together form the seat (4), which distributes the load differently to the foam (5) positioned at the bottom of the box (2).

Description

"SELF ADJUSTABLE PINED SEAT BENCH"

It is the present patent application for an unpublished "SELF-ADJUSTABLE PINED SEAT BANK" notably a simple constructive stool whose highlight is a self-adjusting cushioning system according to the person's weight, which sits on a The seat is configured by a number of independent pins assembled in a box and supported by a foam base that fits according to the load dispensed at the end of each pin, thus resulting in an anatomical product adaptable to different user biotypes.

It is common knowledge that a person spends most of

sitting time, which, if inadequate, proves to be an initially imperceptible spinal trouble factor, but over time results in back pain that often shows severe irreversible trauma.

Therefore, choosing an appropriate sitting artifact is

It is fundamental to clear the temporal degeneration of the spine. In addition to the appropriate dimensions, the artifact represented here by a stool should be seated firmly enough not to force the lower limbs but not inflexible to the point of discomfort to the wearer.

The artifacts known and made available by the market are in their

most of them formed by a single set with foam and / or spring damping media. In these known models, due to the fact that they are monoblocks with regard to damping, there is no equanimous load distribution in the same, which ends up causing discomfort and, as already mentioned, obliging the

user an inappropriate posture while sitting. In order to minimize the above situation, some solutions have been developed that do not completely solve the problem, such as Pl 0404900-4 "Molded Polyurethane Foam with Increased Properties for Better Comfort and Longer Durability". The foam of the invention is produced with polyol components which are largely based on double metal cyanide (dmc). The foams of the invention may be made using any production processes employed in the bulk manufacture of polyurethane seat foam.

The above document, despite improving the mechanical properties of the foam, does not yet resolve the uneven foam deformation as a result of the fact that the load is distributed in one piece.

The same statement can be attributed to MU 8400680-3 "Wooden Spring Bank". It has a wood spring system that through the wood foot systems with spring system providing a moiejo on the seat that brings us great comfort.

Aware of the state of the art, its shortcomings and limitations, the inventor, person, after studies and research, created the "SELF-ADJUSTABLE PINK SEAT BANK" in question, which aims to propose a sitting artifact formed by autonomous components, based on at the junction in a foam-filled box on which several juxtaposed and independent pins are placed that together form the seat, which transfer to that foam the exact load applied to it when a user uses it, thereby shaping itself anatomically its biomechanics. As the pins, although leaning against each other, are independent, the user sitting on them will have the heavier part copied to the foam differently from the lighter part, which will require less of the foam itself that will sink less.

Depending on the weight of the user, the stool may have an intermediate plate between the pins and the foam added, so that excessive impact load when sitting prevents damage to the base foam. Another variation is the combination of springs with the foam and the intermediate plate.

Both the box and the pins can take different shapes and dimensions, meeting the users' physical and ornamental needs.

In short, one can list as the most important advantages of

invented stool:

> Constructive simplicity / design;

> Anatomically correct for different user biotypes;

> Great cost-benefit ratio;

The following explains the stool with reference to the accompanying drawings,

in which they are illustrated by way of illustration and not limitation:

The "SELF-ADJUSTABLE PINED SEAT BANQUET", object of this patent application, consists of a stool (1) formed from a box (2) capable of neatly assembling numerous independent pins (3), which together form the seat (4) which distributes the load differently to the foam (5) positioned at the bottom of the box (2).

10 More particularly, the claimed stool (1) consists of a

box (2), which regardless of shape and size, has numerous juxtaposed and independent pins (3), which together form the seat (4), and at the opposite end, the pins rest in a foam (5) suitably specified to deform to the correct extent of the point load applied to each of said pins (3). In a constructive variation, for heavier users, the stool (1) will have the addition of a loose intermediate plate (6) between the lower ends of the pins (3) and the foam (5), thus avoiding damage to it. since it would deform suddenly and plastically due to being overweight. Finally, in a second embodiment variation the stool (1) may combine a set of springs (7) immediately after the bottom of the box (2), followed by the foam (5) and the intermediate plate (6).
