FURNITURE SUPPORT DEVICE

DESCRIPTION Object of the invention

The present invention, as expressed in the statement of this specification, refers to a support device for furniture comprising at least one arcuate piece of plastic material that adapts to the edge of a base of furniture, such as chairs, armchairs, stools, tables, etc .; so that the furniture rests on the floor by means of that arched piece, thus obtaining a seat that protects the base of the furniture by avoiding its direct contact with the floor, thus preventing the deterioration of said base as well as the scratching of the floor.

Starting from this premise, the objective of the invention is that the arcuate pieces of plastic material remain stably anchored at all times to the edge of the furniture base, even when the furniture is dragged, standing out that conventionally other furniture incorporating Semi-rigid profiles in their metal bases, after time they end up dislodging from their location, especially when they are dragged, constituting this fact an obvious problem that is solved with the device of the invention.

Technical problem to solve and background of the invention

At present there are many furniture, among which those that have metal bases that have perimeter edges of closed contours where semi-rigid profiles that support the ground are coupled, thus avoiding direct contact of the perimeter edges of the metal bases on the ground. These semi-rigid profiles have a simple structure of rectangular, universal and non-specific section; so that said semi-rigid profiles do not adapt well to the edges of the metal bases or to the ground on which they rest, which causes them to be easily released, with the consequent problems that this entails.

Although this described solution prevents in principle the premature deterioration of the base and the scratching of the floor where the furniture rests, it should be noted that the anchor of the semi-rigid profile is a weak anchor that is unable to maintain the stable position of said semi-rigid profile after time, especially when the furniture is dragged, which

The semi-rigid profile ends up disengaging from its coupling in the edge of the furniture base.

In this situation, every time the semi-rigid profile is disengaged from its location, it is necessary to put it back in its place, generating the repetition of this problem a vice of the deformation of the semi-rigid profile that increasingly enhances the removal of it. ; with which in the end it is necessary to change it to another new semi-rigid profile with the added expense that this implies; generating all this in addition to a great discomfort for the user of the furniture that also sees how the disengagement of the semi-rigid profile causes instability in the seat of said furniture on the floor.

Description of the invention

In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes a support device for furniture comprising at least one arcuate piece that is coupled on a perimeter edge of closed contour that forms part of a belonging base to a piece of furniture

Description of an example of realization of the invention

Considering the numbering adopted in the figures, the support device for furniture comprises two arched pieces (1) of plastic material that are coupled on a perimeter edge (2) of closed contour that forms part of a metal base (3) belonging to a furniture (4), so that the perimeter edge (2) of the base comprises a lower section (2a), an upper section (2b) and a curved intermediate section (2c) where the other two sections converge: lower (2a) and higher (2b).

Thus, the furniture (4) rests on a floor (5) by means of the two arched pieces (1), obtaining a characteristic seat of the furniture assembly (4) that

prevents the deterioration of the soil (5) and also the deterioration of the base itself (3) of the furniture (4). The arched pieces (1) comprise a section delimited by an upper face (1a), a lower face (1b) that is in contact with the ground (5), an internal lateral face (1c) and an external lateral face (1d) where an angular step (6) is formed in combination with a canalization (7). These two elements (6), (7) form a support surface (8) on which the lower section (2a) of the perimeter edge (2) of the base (3) of the furniture (4) sits.

An edge of the perimeter edge (2) stops against a bottom (7a) of the continuous channeling (7) of the arched pieces (1).

On the other hand, a posterior portion (9) of the upper face (1a) of the arched pieces (1) contacts and fits against an internal face (10) of the upper section (2b) of the perimeter edge (2) of the base (3), so that this contact between the arched pieces (1) and the inner face (10) of the perimeter edge (2), together with the seat on the support surface (8) of the arched pieces (1), ensure the anchoring of said anchoring pieces (1) to the perimeter edge (2) of the base (3). This avoids the release of said arched pieces (1), even in the case of dragging the furniture (4) through the floor (5).

The rear portion (9) of the upper face (1a) of the arcuate pieces (1) comprises an extreme elevation that is in contact with the inner face (10) of the upper section (2b) of the perimeter edge (2) of the base (3).

The edges of the arched pieces (1) have a rounded configuration as described below.

The two arched pieces (1) incorporate at their opposite ends male and female elements that fit together, where the male element of one of the arched pieces (1) comprises an extension (11) that is embedded within a recess ( 12) constitutive of the female element of the other arched piece (1) pair.

Thus, considering a first arched piece (1), one end integrates an extension (11) and the opposite end integrates a recess (12), so that this first arched piece (1) joins a second arched piece (1 ) which also has at its opposite ends the extension (11) and recessed (12).

Each of the arched pieces (1) incorporates in its upper face (1a) a groove (16) that reaches the entire length of the arched pieces (1), with the exception of a first end section (13) adjacent to the extension ( 11) and a second end section (14) that is longer than the end section (13). The second end section (14) integrates the recess (12) (female element) in its entire extension.

The continuity of said groove (16) is interrupted by several intermediate fins (15) that help stiffen the structure of each of the arcuate pieces (1).

The second end sections (14) of the two arched pieces (1) allow the total length of the contour formed by them to be adapted to the length of the perimeter edge (2) of the base (3) of the furniture (4). To do this, you can cut a few pieces of the second extreme sections (14).

The confluence of the lower face (1b) and inner side face (1c) of the arcuate pieces (1) comprises an internal rounded edge (17). Each arched piece also comprises an external rounded edge (18) located at an opposite end to said internal rounded edge (17), so that the lower face (1b) of the arched pieces (1) is delimited between these two rounded edges: internal (17) and external (18), and not by sharp edges as in other conventional devices.

The assembly of the arched pieces (1) on the edge (2) of the base (3) of the furniture (4) avoids gaps, thus achieving a better grip of said arched pieces (1) and therefore the possibility of their disengage

The rear portion (9) of each arched piece (1) is located in an area adjacent to a rounded edge (19) delimited by the confluence of the upper face (1a) of the arched piece (1) and a corresponding plane with a vertical branch of the angular step (6) arranged in correspondence with an external lateral face (1d) of the arcuate piece (1); where a corresponding plane with a horizontal branch of the angular step (6) constitutes part of the support surface (8) on which the lower section (2a) of the edge (2) of the base (3) of the furniture (4) sits .

The form of adjustment of the two arched pieces (1) at their ends configures a

closed frame structure that adapts perfectly to the perimeter of the edge (2) of the base (3) of the furniture (4), without gaps; thus achieving a perfect fit that avoids that in the most unfavorable uses said frame structure (formed by the two arched pieces (1)) can be dislodged or expelled.
