Description

The invention relates to the field of folding furniture, and more particularly, to the connecting pieces positioned between the legs and the flat surface of the folding furniture.

Conventionally, the folding furniture comprises a flat surface or other support surface to which legs are attached.

As known, the legs extend, when deployed, in a direction substantially parallel to the plane of the flat surface when folded.

Generally, the legs of the folding furniture are hinged in order to be folded against the flat surface. The hinge mechanism and the associated hinge members are traditionally placed under the flat surface of the furniture and preferably at the periphery of the latter, particularly in each corner when the flat surface is of parallelepipeds shape. Unfortunately, this positioning has the effect that the hinge mechanism and the associated hinge members fall within the field of view of a person in the vicinity when the furniture is in the deployed position, which is a defect from an aesthetic point of view. In addition, fastening of these elements on the flat surface is not very easy.

In some known folding furniture, the hinge mechanism is offset from the center of the flat surface to prevent the latter from being visible; however, the mechanism becomes bulky and inconvenient.

The invention aims to overcome all or some of the aforementioned disadvantages.

The invention relates to a connecting piece for a folding table designed to connect legs with a tabletop, characterized in that said connecting piece comprises:

• • a base designed to be in contact with the tabletop,
  • at least a first housing extending in a direction along a longitudinal axis, the first housing having a first open end for insertion of a reinforcing bar and a second closed end,
  • a fastening portion provided on the side of the second end of the first housing, the fastening portion being offset relative to the longitudinal axis of the first housing so that the fastening portion is facing outward of the tabletop once the connecting piece is fastened to the tabletop.

Thus, such an offset of the fastening portion relative to the first housing allows to visually conceal the first housing and the reinforcing bar of the folding table since the latter are thus at a greater distance from the periphery of the tabletop.

According to a feature of the invention, the fastening portion comprises a single fastening member configured to fasten the connecting piece to the tabletop of the folding table. The use of a single fastener makes it possible to reduce costs and to simplify the fastening of the legs on the tabletop.

According to a feature of the invention, the first housing comprises a fastening member configured to fasten the reinforcing bar to the connecting piece.

According to a feature of the invention, the connecting piece comprises a second housing extending in a direction along a longitudinal axis, the longitudinal axis of the second housing intersecting with the longitudinal axis of the first housing.

Advantageously, the arrangement of the second housing with respect to the first housing provides a shaped connecting piece adapted to the shape of part of the tabletop of the folding table, preferably a corner. The angle formed by the first housing and the second housing is variable depending on the geometry of the tabletop and of the fastening zone of the connecting piece. Preferably, the second housing extends in a direction substantially perpendicular to the first housing.

According to a feature of the invention, the fastening portion has a shape adapted to be positioned in a corner of the folding table. Preferably, the fastening portion has an oblong shape with a rounded portion which substantially fits with a rounded corner of the tabletop.

According to a feature of the invention, the second housing includes an open first end for insertion of a reinforcing bar and a second closed end, the fastening portion being positioned on the side of the second end of the second housing.

According to a feature of the invention, a projection is provided on at least a portion of the periphery of the base of the connecting piece. Thus, the connecting piece has a larger contact surface with the tabletop, thereby improving the retention of the tabletop on the legs and increasing the resistance of the connecting piece to the stresses exerted by the tabletop.

The invention also relates to a folding table reinforcing system, characterized in that the reinforcing system comprises at least one connecting piece according to the invention, at least one reinforcing bar, said reinforcing bar being inserted into a first housing of the connecting piece.

According to a feature of the invention, the reinforcing system comprises at least a first connecting piece and a second connecting piece, the first connecting piece being connected to the second connecting piece by a reinforcing bar. Advantageously, each connecting piece is fastened to the table top via the single fastening member provided at the respective fastening portion. Joining the first connecting piece with the second connecting piece can limit the risk of rotational movement of each connecting piece.

According to a feature of the invention, the reinforcing system has a parallelepipedic shape and includes four connecting pieces, each of the connecting pieces being positioned at a corner of said reinforcing system. The reinforcing system thus designed allows for discreet reinforcing and supporting of the edges of the tabletop of the folding table. In addition, the connecting pieces being all joined to each other by reinforcing bars, the reinforcing system is self-supporting and requires only four points of fastening to the tabletop, the fastening points each being respectively allocated to a fastening portion of a connecting piece. Advantageously, the connecting pieces are positioned in the corners of the parallelepipedic tabletop of the folding table and the reinforcing bars are set back relative to the tabletop edges.

Of course, the number of connecting pieces is not limited to two or four, the reinforcing system is intended to include one or more connecting pieces according to the geometry of the tabletop of the folding table.

The invention will be better understood from the following description, which relates at an embodiment according to the present invention, given by way of non-limiting example and explained with reference to the accompanying diagrammatic drawings in which:
