Stackable stool

Abstract

Stackable stool, of those structured into an upper seat (1) and a lower support (2) joined together by a core/column (3), where the seat (1) has a groove (11) and the support (2) has a groove (21). These grooves (11), (21) are placed in opposite directions and are centred with respect to the core/column (3), and the widths (a1), (a2) of these grooves (11), (21) are able to house the core/column (3), so that, in order to snack stools it is sufficient to house the ends of the core/column (3) of one of them, respectively into the groove (11) of the next stool and in the groove (21) of the previous stool, with their cores/column (3) placed against each other.

Description

In the current state of the technique seats of the type known as “stools” are already known, for example proceedings EP1024731, U200400398, U9303489 and even stool-seats that are stackable, for example, and among others, Spanish Utility model U152441.

The subject of the invention is a new stackable stool whose particular structure permits stacking, occupying very little space, which is increased, in height and width, by minimal dimensions as new stools are added to the stack, so that several stools (for example four or five), occupy only a slightly larger volume than the volume occupied by one single stool.

The stackable stool according to the invention is of the kind made up of an upper seat and a lower support joined together by a core/column where a footrest may or may not be placed, and it is characterised because:

a) the seat has a groove and the support has a groove, which, starting from their respective edges, reach an area close to the respective central area of the seat and the support from where the core/column that joins them together starts;

b) the groove of the seat and the groove of the support are placed in opposite areas of the stool;

c) the widths (a₁) of the groove of the seat and (a₂) of the groove of the support are similar to each other and combined of the width (a₃) of the core/column that they house.

With this structuring, to stack stools, it is sufficient to house one end of the core/column of one of them in the groove of the seat of the next stool and the other end of the core/column in the groove of the support of the previous stool; with their cores/columns up against each other.

In particular, the groove is placed as from the front edge of the seat and the groove is placed as from the rear edge of the support, although any other location/placement of the grooves is included in the subject of the invention.

In order to understand the subject of this invention better, a preferential form of practical execution is illustrated on the drawings, subject to incidental changes that take nothing away from its foundation.

FIG. 1 shows a general schematic view in two positions, front —FIG. 1a— and rear —FIG. 1b— of a stackable stool according to the invention, for a configuration with footrest (4).

FIG. 2 shows a general schematic view in two positions, front —FIG. 2a— and rear —FIG. 2b— of a stackable stool according to the invention, for a configuration without footrest (4).

It is indifferent and incidental for the purpose of the invention that the stackable stool has a footrest (4) or does not.

Below an example of a non-limitative practical execution of this invention is described. Other execution modes are not rejected at all where incidental changes are introduced, which take nothing away from its foundation; on the contrary, this invention also covers all its variants.

The subject of the invention is a new stackable stool of the kind structured into an upper seat (1) and a lower support (2) joined together by a core/column (3).

It is indifferent and incidental for the purposes of the invention that the stackable stool has a footrest (4) in its core/column (3)—as in FIGS. 1a and 1b—or does not have one—as in FIGS. 2a and 2b—.

In agreement with the invention:

the seat (1) of the stool has a groove (11)

the support (2) of the stool has a groove (21).

These grooves (11), (21) starting from their respective edges, reach an area close to the respective central area of the seat (1) and of the support (2) where the core/column (3), which joins them, starts.

In particular, the groove (11) starts from the front edge of the seat (1) and the groove (21) starts from the rear edge of the support (2), although this placement is not limitative.

The widths (a₁) of the groove (11) and (a₂) of the groove (21) are similar to each other and combined of the width (a₃) of the core/column (3) that they house without play on stacking some stools onto others.

This combined dimensioning, although not essential, is very advisable, to avoid relative movements between the stools when they are stacked.

In any case, the widths (a₁), (a₂) of the grooves must be combined or greater than the width (a₃) of the cores/column (3).

With all of this, to stack structured stools, either according to FIG. 1 or else according to FIG. 2, it is sufficient to house the ends of the core/column (3) of one of them, respectively in the groove (11) of a next stool and in the groove (21) of a previous stool, with their cores/column (3) placed up against each other.

Claims

1. Stackable stool, of those structured into an upper seat (1) and a lower support (2) joined together by a core/column (3), where the seat (1) has a groove (11) and the support (2) has a groove (21). These grooves (11), (21) are placed in opposite directions and are centred with respect to the core/column (3), and the widths (a1), (a2) of these grooves (11), (21) are able to house the core/column (3), so that, in order to snack stools it is sufficient to house the ends of the core/column (3) of one of them, respectively into the groove (11) of the next stool and in the groove (21) of the previous stool, with their cores/column (3) placed against each other.

2. Stackable stool, according to previous claim, characterised because, above all, groove (11) is placed as from the front edge, seat (1) and groove (21) are placed as from the rear edge of the support (2).
