Description

The invention relates to a fastening device for a furniture leg, intended to form part of a furniture base system, and in particular a frame with mountable kit elements, for fastening furniture legs. , the frame can advantageously serve as a support for a furniture tray type table. The invention will be more particularly described with reference to a table-type furniture, without being limited thereto. The footrest attachment device of the invention is intended for any type of furniture that requires the arrangement of vertical feet to support a horizontal surface. In the field of tables or desks, many pieces of furniture are offered as kit elements for mounting. These furniture are also removable when necessary. Such furniture comprises, for example, profiles to be screwed together to form a frame, as well as feet or uprights which are fitted against the corners of the frame via fixing plates, to be screwed on the one hand to the frame and on the other hand to the frame. part to the feet. Other systems provide connecting pieces or wedge for the one hand to allow the abutment and attachment of the frame profiles, and 25 on the other hand constitute receiving housing and fixing feet. However, these aforementioned devices ultimately require additional pieces of connection.

To increase the speed of mounting feet, it is also known table trays whose corners have female parts in which the feet are snapped or other fastening system. However, this type of furniture requires a frame or a tray made of one piece. The invention therefore aims to provide a fixing device for furniture leg, from several elements to be mounted, which limits the number of parts to be mounted and allows a quick and convenient attachment of a foot.

According to the invention, the furniture foot fixing device, intended to form part of a furniture base system, and comprising at least two elongate or profiled elements intended to be associated with each other by means detachable fixation, each section comprising a core and a distal end or association end, is characterized in that the endings of the two sections respectively have a half-shell shape, the two half-shells being intended to cooperate facing the from one another to form a receiving sleeve of one end of the foot.

Thus, the half-shell integrated to each of the profiles once allows the associated profiles, firstly to form a corner of the base system of a tray furniture and secondly to directly form the home and attaching the foot to associate with the corner of the furniture.

The device of the invention does not require additional parts to report to the profiles forming the frame, to associate the feet. In addition, the assembly remains mountable and removable, including the feet relative to the table. The profiles can remain elements in kit to be assembled on the spot or are delivered already mounted, only the feet being to assemble.

Editing is fast and easy. The device thus directly constitutes the means for housing and fixing the furniture foot and advantageously form the support means of the furniture tray.

According to one characteristic, the end of the first profile comprises a return which extends in the extension of the core and substantially perpendicular to the core to form the half-shell of said first termination, this half-shell defining a hollow space to concavity turned towards the soul. According to another characteristic, the termination of the second profile comprises a bend which extends substantially perpendicularly to the core of said profile, and forms the half-shell of said termination delimiting a concavity housing turned towards the opposite of the core. said profile. Preferably, the half-shell or the return of the first section comprises opposite the web of said profile, a bracket, preferably extending in a plane parallel to and in the direction of the core, said bracket fixing being intended to be fixed to the beginner portion of the half-shell of the second section which is connected to the core of said second section, while the half-shell of the second section comprises the opposite the beginner portion, a tab of fixing, preferably extending in a plane perpendicular to the core, intended to be fixed to the core of the first profile. In this way, the two terminations incorporate cooperation means allowing the association of the profiles with each other. Advantageously, the sections are joined together perpendicularly. According to another characteristic, the two half-shells have a semi-cylindrical internal wall, in particular of semi-circular section, to accommodate a cylindrical foot of complementary section to the section formed by the two half-shells.

Preferably, each of the webs of the two sections comprises at least one longitudinal wing perpendicular to the core and intended to form a support area of a tray or other similar reception area furniture.

Advantageously, the two sections are identical, each section having two endings of different shapes, one end being complementary to the other. This greatly simplifies the manufacture of the device, only a single particular form of profile being manufactured. However, it is possible to manufacture two separate profiles each with two identical terminations, the proper termination of one being intended to cooperate with the clean and distinctly shaped end of the other profile, the two different forms of termination forming the sleeve receiver.

The device comprises four profiles, ie two pairs of identical profiles, the two profiles of a first pair each having two identically shaped terminations, the two profiles of the second pair each having two identically shaped terminations, one of the endings of the second pair. a section of a pair being of complementary shape to a termination of a profile of the other pair. The invention also relates to an assembly comprising at least one device of the invention and at least one foot of furniture, preferably the foot being friction-fitted in the sleeve of the two assembled sections. Such foot cooperation has the advantage of not requiring reported securing means. Finally, the invention relates to a piece of furniture, in particular a table, comprising at least one device of the invention or the preceding assembly, and a plate associated with the device opposite the feet, preferably the furniture having two devices with four profiles to form at least two sleeves housing at least two respective feet, In the remainder of the description, the terms "horizontal", "vertical", are qualified by qualifying the elements in the context of a normal installation of the device, that is to say relating to a vertical concept in relation to a flat horizontal floor on which the feet of a piece of furniture would be placed.

The present invention is now described with the aid of examples which are only illustrative and in no way limit the scope of the invention, and from the attached illustrations, in which: FIG. 1 represents a partial exploded perspective view of the fixing device of the invention, a table leg and a table top; FIG. 2 is a perspective view from below and from the side of a table corner showing the device of FIG. 1 assembled; FIG. 3 is a perspective bottom and bottom view of a table corner showing the device of FIG. 2; - Figures 4A and 4B are perspective views, each of a type of profile with identical terminations; - Figure 5 is a schematic top view in section of a frame formed from two assembled devices of the invention (four profiles), and the associated feet; - Figure 6 is a perspective view and detail of the terminations of two profiles of the device of the invention; - Figure 7 is a partial top view and exploded of the device of the invention before assembly; - Figure 8 is a partial top view of the device after assembly of the two sections; - Figure 9 shows the assembly of Figure 8 with the foot in place. The fixing device 1 for furniture leg, such as a table, illustrated in Figures 1 to 3 is intended to form, after assembly by removable fastening means 7, a portion of a base system. The latter comprises a frame 10 of square or rectangular shape, to accommodate one of the ends of a foot 4 of said furniture. Figures 1 to 3 are partial views showing a corner of the frame and the table and its tray.

With reference to FIG. 5, the frame 10 advantageously consists of four sections 1A1, 1A2, 1B1 and 1 B2, ie two fastening devices 1 assembled to form the four sides and to fix four vertical feet 4A, 4B, 4C and 4D each formed of a hollow section tube cylindrical. The assembly (frame and feet) composes the base system of the table and supporting the plate 5 of said table visible in Figures 1 to 3. With reference to FIGS. 1 to 3, the fixing device 1 of the invention comprises at least two (and preferably four) sections 1A and 1B which are intended to be abutted and assembled at one of their endings, respectively 2 and 3. Each end forms a half-shell and cooperates with the other so as to form a receiving sleeve 6 for accommodating one of the ends of the foot 4.30 Advantageously, the profiles 1A and 1B intended to be associated with the to one another, are different, as illustrated in Figures 4A and 4B. Here, to form a square or rectangular frame, two pairs of profiles (a pair 1A1 and 1B1, and a pair 1A2 and 1B2) are associated to thereby form the frame 10 and four sleeves 6A, 6B, 6C and 6D (Figure 5) reception desk for the feet. Each section 1A, 1B (Figures 1, 4A and 4B) comprises a core 11 and two respective endings (2A, 2B) and (3A, 3B) of identical shape. The profiles 1A1 and 1A2 (FIGS. 4A and 5) are identical and each have identical terminations 2A and 2B. The profiles 1B1 and 1B2 (FIGS. 4B and 5) are identical and each have identical terminations 3A and 3B.

The terminations 2A and 2B (FIG. 4A) of the sections 1A1 and 1A2 each form a substantially cylindrical half-shell, open, whose concavity 20A, 20B is oriented towards the face of the core intended to be turned towards the inside of the frame (Figure 5).

The terminations 3A and 3B (FIG. 4B) of the profiles 1B1 and 1B2 each form another open half-shell whose concavity 301, 30B faces towards the outside of the profile (towards the outside of the frame 10), in the opposite direction the other end 2, and angularly with respect to the parallel plane of the core 11.

The frame 10 is formed of two pairs of devices 1 of the invention, each pair being the assembly of the two sections 1A1 / 1B2 and 1A2 / 1B1. Once the first pair assembled (Figures 2 and 3), the assembly of the other two profiles of the second pair is made by having previously returned each of said profiles relative to a horizontal plane. More particularly, with reference to FIGS. 1 and 6, each profile 1A, 1B has, in cross-section, a generally U-shaped shape, and comprises a longitudinal core 11 extending, in the mounted position of the device, in a vertical plane, and two longitudinal wings 12 and 13 opposite, perpendicular to the core and integral with the opposite longitudinal edges of the core. The longitudinal wing 12 for the first pair of profiles 1A and 1B and the longitudinal wing 13 for the second pair of profiles (which have been turned in relation to the horizontal) constitute a bearing surface for the plate 5 intended to rest on the frame 10 (Figures 2, 3 and 5). The face 11A of the core 11 forming the bottom of the U of the profile, arranged between the flanges 12 and 13 and turned on the inside of the frame 10, is called the inner face of the core, because it is intended to be oriented towards the inside of the frame 10 (Figures 2 and 3). The first termination 2A, 2B of each profile 1A1, 1A2 constitutes the extension of the core 11 according to a return 21, here curved, substantially perpendicular to the core, to delimit a hollow space or a semi-cylindrical half-shell whose concavity 20 is rotated substantially perpendicularly and towards the inner face 11A of the core 11.

The wings 12 and 13 of the profile stop at the beginning of the return 21 to provide in the profile and at the wings planes, two opposite inlet ports 22 and 23. Depending on the position of the profile 1A, 1A2, returned or not, the orifice located in the lower part (in this case in Figures 1 and 6, the orifice 23) allows the introduction of the foot 4 in the half-shell of the curved return 21.

Advantageously, the return 21 comprises at its distal end, opposite the core 11, a fastening tab 24 extending along the width of the core and in a plane parallel to the core 11, opposite the inner face 11A. Each end 3A, 3B of each profile 1B1, 1B2, forms a bend 31, here curved, in the extension of the core 11 delimiting a semi-cylindrical half-shell open towards the opposite of the inner face 11A of the soul. The elbow 31 starts from the distal edge of the core 11 by a wall 32 orthogonal to the core, then a semi-cylindrical wall 33 whose convexity is turned towards the inner face 11A of the core and the inside. of the profile, and ends with a fixing lug 34 extending in a plane perpendicular to the core 11.

The concavity 30 of the wall 33 of the profile 1B is of complementary shape to the concavity 20 of the end 2 of the other profile 1A, to form a cylindrical shell constituting the receiving sleeve 6 of each foot (Figure 5).

As for the termination 2A, 2B, the elbow 31 is open at its distal ends, at the planes of the wings 12 and 13 of the core 11 to form through holes 35 and 36 for the introduction of the corresponding foot. .

The section of the semi-cylindrical half-shells of the terminations 2 and 3 (profile or shape of the concavities 20 and 30) has a shape adapted to the section of the foot of furniture. In the example shown, the section of each half-shell is semicircular to produce a cylindrical sleeve of substantially circular section. The section could of course be straight-edged to fit a foot polygonal section (square section, triangular, etc ....). Referring to Figures 1 and 6, the bracket 24 of the terminal 2 and the orthogonal wall 32 and the bracket 34 of the second terminal 3 are used to fix the sections 1A and 1B between them. Preferably, the fastening lug 24, the orthogonal wall 32 and the fastening lug 34 as well as the web 11 of the profile 1A close to the end 2, comprise bores 8 for the passage of fastening means, preferably by bolting. The references of each element are of the alpha-numeric type, in that, for example (FIG. 4A), the profile 1A1 comprises elements that go in pairs: two terminations 2A, 2B; two returns or legs 24A, 24B. Likewise, the references 11, 12 and 13 are associated with the letters A and B for each type of profile (type 1A - FIG. 4A or type 1B - FIG. 4B). Finally, the two profiles 1A (respectively 1B) are distinguished from each other by the addition of respective numbers "1" and "2". The two sections are assembled as follows. Starting from the position shown in FIGS. 1, 6 and 7, the end 3 of the section 1B is brought together and then placed against a first end 2 of the first profile 1A, as illustrated in FIG. 8. The profiles are thus joined together. and are fixed without additional piece of connection and corner, the terminations 2 and 3 cooperating to form a wedge and a receiving housing for the foot of furniture to report.

In this abutment position, the fastening tab 24 of the end 2 bears against the orthogonal wall 32 on the side of the concavity 30 of the bend 31 with their respective bores facing each other, while the fixing lug 34 of the second end 3 bears against the inner face 11A of the first section with their respective bores opposite. The assembly is then bolted via fastening means 7, at the bores 8 to form the assembly of FIG. 8. The assembled and fixed profiles 1A and 1B, the foot 4 can then be fitted into the receiving sleeve 6 (FIG. formed by the two half-shells opposite). Advantageously, the dimensions of the receiving sleeve 6 are designed to fix the foot 4 by interlocking with friction only, without additional fastening means.
