Description

The present invention relates to the field of bedding, and more specifically the devices for the removable attachment of an insert on the frame of a bed base. In the field of bedding, it may be useful to equip the frame with a bed frame with devices for the removable attachment of an insert (for example to fix a headboard, a decorative long-pan or frame another mattress). For example, to accessorize a box spring frame, the decorative elements (headboard, long-pan, etc.) can be secured to one of the stringers of the bed frame by means of simple screws; but there are still other means of solidarity. However, most of these current fasteners are relatively tedious to set up and they do not ensure optimal positioning and maintenance of the insert on the bed frame. They are also, for some, subject to jamming, making it difficult to dismantle the secured elements. In this context, the Applicant has developed a new device for the removable attachment of an insert on the frame of a bed base, this in a simple, fast and effective way.

The corresponding bedding structure comprises a bed frame frame, one of whose longitudinal members comprises an outer face on which is mounted removably an insert, by means of a fastening device; and this fixing device comprises at least two pairs of assembly members which each consist of: (i) a receiver assembly member fixed to the spar of the bed frame, which is provided with a rear face contact with said spar, and - at least two front hooks, arranged one above the other, on the same vertical axis, and each delimiting an upward longitudinal groove, and (ii) d a complementary assembly member attached to said insert, which is provided with a rear face of contact with said insert, and at least two front hooks, arranged one above the other , on the same vertical axis, and each delimiting a longitudinal groove oriented downwards.

In addition, the receiver assembly members of the two pairs of assembly members are fixed on said spar at a given distance A from each other; and the complementary members are fixed on the insert element at a distance A identical, or approximately identical.

Such a structure allows cooperation between the hooks of a receiver assembly member and the complementary hooks of a complementary assembly member, to obtain a particularly effective fastening device and simple to implement. According to an interesting embodiment, at least some of the hooks equipping the assembly members consist of an L-shaped cross-section structure which consists of a horizontal wing extended by a vertical wing extending in a plane shifted towards the front relative to the plane passing through the rear face of said assembly member. In this case, the hooks of the complementary assembly member 15 advantageously comprise a vertical wing extending the horizontal wing downwards, and the hooks of the receiver assembly member comprise a vertical wing extending the horizontal wing towards the top. Again in this case, the vertical flange of at least one of the hooks of the receiver latching member advantageously cooperates by contact with the vertical flange 20 of its complementary hook equipping the complementary assembly member, and the corresponding vertical wings comprise interlocking locking means, for example of the rib / groove type. According to a particular embodiment, at least one of the assembly members has two transverse edges, one upper and the other lower, with a first hook extending at a first transversal edge and a second hook extending between the second transverse edge of said assembly member and said first hook. In this context, a first assembly member advantageously comprises a front wall, extending in a plane offset forwards with respect to the plane of its rear face, of which a transverse end band forms part of the first hook. , and said front wall being provided with an opening adjacent to the second hook for the passage of the second hook fitted to a second connecting member intended to be associated with it. According to another characteristic, a first assembly member advantageously has a generally rectangular shape delimited by two parallel lateral edges separated by a first distance E and by two transverse edges; the second assembly member also has a rectangular shape, delimited by two parallel lateral edges and by two transverse edges, the lateral edges of said second assembly member being extended by lips projecting towards the front, the inner faces of which are opposite. are separated by a second distance F which is slightly greater than said first distance E, for receiving, between them, the first assembly member. The second hook of the second assembly member advantageously comprises a width G, which is smaller than the second distance F, so as to define two lateral grooves for the positioning of the first assembly member. In addition, the lateral edges of the first assembly member advantageously comprise lips projecting rearwardly, the outer faces of which are separated from the first distance E, to cooperate with the projecting lips of the second assembly member. According to a possible embodiment, the first assembly member constitutes the receiving member, fixed on the bed frame frame spar; and the second assembly member constitutes the complementary member, fixed on the insert.

The present invention also relates to the device for attaching an element to the spar of a box spring frame, which fixing device comprises at least two pairs of assembly members each consisting of a receiving member and a complementary organ as defined above.

The invention will be further illustrated, without being limited in any way, by the following description of a particular embodiment, in relation to the appended drawings in which: FIG. 1 is a general and perspective view of a bed base on which is removably reported, an element of the headboard type by means of the fixing device according to the invention; - Figure 2 is a schematic representation of the bed frame of Figure 1, according to a longitudinal sectional plane passing through a pair of assembly members constituting the fixing device; - Figure 3 is a partial and enlarged view of Figure 2, showing the pair of assembly members in section; - Figure 4 still shows the bed frame of Figure 1, with the headboard dissociated from the bed frame; - Figure 5 is a general view of the receiver assembly member, intended to be fixed on the bed frame, in a perspective oriented 1 o the side of its front face; - Figure 6 still shows the assembly member of Figure 5, here according to a perspective oriented on the side of its rear face; - Figure 7 shows the assembly member of Figures 5 and 6, in a front view; FIG. 8 shows the assembly member of FIGS. 5 to 7, in a longitudinal sectional view; - Figure 9 shows the connecting member of Figures 5 to 8, in a rear view; - Figure 10 is a general view of the complementary assembly member 20, intended to be fixed on the insert, shown in a perspective oriented on the side of its front face; - Figure 11 also shows the assembly member of Figure 10, here according to a perspective oriented on the side of its rear face; Figure 12 shows the connecting member of Figures 10 and 11 in a rear view; - Figure 13 shows the connecting member of Figures 10 to 12, in a longitudinal sectional view; - Figure 14 shows the assembly member of Figures 10 to 13, in a front view. The bedding structure 1 according to the invention, shown in FIGS. 1 to 4, comprises a bed frame 2 equipped here with an insert element 3 consisting of a headboard. The box frame 2, of rectangular shape, consists of two pairs of longitudinal members, namely two transverse longitudinal members 4 and two longitudinal longitudinal members 5, each having an outer face 4a and 5a respectively. This bed frame 2 is further equipped here - a set of slats L, distributed over the length of the longitudinal beams 5 and intended to receive a mattress, and - feet P reported at its corners. The headboard 3 comprises in particular a front face 3a, extending facing the outer face 4a of the spar 4 associated therewith. This headboard 3 is removably mounted on the outer face 4a of one of the transverse longitudinal members 4, by means of the attachment device 10 according to the invention. As shown in FIGS. 3 and 4, this fixing device 10 consists of pairs of assembly members 11, 12, here two in number (assembled in FIG. 3 and separated in FIG. 4). The two pairs of assembly members 11, 12 are spaced apart from each other by a horizontal distance designated by the reference A in FIG. 4. Each pair of assembly members 11, 12 is composed of - A receiver assembly member 11, fixed on the outer face 4a of the spar 4 of the bed frame 2, and - a complementary assembly member 12, 20 fixed on the front face 3a of the headboard 3. The fastening device 10 thus comprises two receiver assembly members 11 which are fixed at a distance from each other on the spar 4, according to the horizontal distance A above. The complementary assembly members 12 are fixed on the headboard 3, 25 so as to be separated from each other also from this same horizontal distance A. The assembly members 11 and 12 are advantageously made each one-piece for example by injection of a plastics material of the polyamide type filled with glass fibers, or polycarbonate. The receiver assembly member 11 and its complementary assembly member 12 comprise complementary structures in the form of hooks which are intended to cooperate by interlocking for their removable mechanical connection. The receiver assembly member 11 is described below in connection with FIGS. 5 to 9.

This receiver assembly member 11 consists of a plate of generally rectangular shape, comprising - a rear face 15 intended to come into contact with the spar 4 and - a front face 16 intended to come opposite the headboard 3 .

To cooperate with the complementary assembly member 12, this receiver assembly member 11 comprises two front hooks 17 and 18 whose section has a general shape of L (Figure 8); these hooks 17 and 18 still have a dihedral or angle form. Once reported on the outer face 4a of a receiving beam 4 (shown schematically in Figure 8), these hooks 17 and 18 each define a longitudinal groove 17a and 18a, respectively, opening upwards. The hooks 17 and 18 are arranged one above the other, on the same vertical axis, to form an upper hook 17 and a lower hook 18. To form these hooks 17 and 18, the assembly member receiver 11 here comprises a front wall 19, of generally rectangular shape, extending in a plane shifted forward with respect to the plane of its rear face 15 (Figure 8).

The front wall 19 is delimited - by an upper edge 19a - by a lower edge 19b and - by two side edges 19c. It further comprises - a front face 19d, forming the front face 16 of the assembly member 11, and - an opposite rear face 19e. This front wall 19 also has an opening 20, of generally rectangular shape and extending over part of its length. The opening 20 is defined in particular by a lower intermediate rim 19h, extending parallel to the upper and lower edges 19a and 19b of the front wall 19. On the side of its rear face 19e, this front wall 19 comprises two lips projecting towards the rear, one upper 21 and the other lower 22, extending parallel and close respectively to the upper edge 19a of the front wall 19 and the lower transverse edge 19h of the opening 20 (FIG. 8 and 9).

The upper projecting lip 21 and the upper edge 19a of the front wall 19 together define an upper transverse end band 23 of the front wall 19. Similarly, the lower projecting lip 22 and the lower intermediate edge 19h of the front wall 19 together define a lower transverse strip 24 of the front wall 19 (Figures 6, 8 and 9). The rear face of this lower band 24 is here provided with a transverse groove 24a intended to cooperate with a rib complementary to the associated assembly member 12 (hereinafter described with reference to FIG. 3). The upper hook 17 of the receiver assembly member 11 is thus constituted by - the upper lip 21, forming a horizontal flange, and - the upper band 23 of the front wall 19, forming a vertical flange. The lower hook 18 of this receiver assembly member 11 is itself constituted by - the lower lip 22, forming a horizontal flange, and - the lower band 24 of the front wall 19, forming a vertical flange. This lower hook 18 is located here between the lower edge 19b of the front wall 19 and the upper hook 17. The transverse strips 23 and 24, each forming the vertical wing of one of the hooks 17 and 18, extend upwards. their lips 21 and 22 respectively, and they extend here in the same plane shifted forward with respect to the plane passing through the rear face 15 of this assembly member 11. This front wall 19 is extended, along each of its two side edges 19c, by a longitudinal lip 25. The longitudinal lips 25 each extend between the lower edge 19b of the front wall 19 and the upper transverse lip 21. The distance E between the outer faces of these two lips longitudinal 25 is adapted to cooperate with the complementary assembly member 12 as described below. This distance E corresponds to the constant width of the receiver assembly member 11. To be complete, these lips 25 also constitute the lateral edges of the opening 20 above.

The rear wall 19 also has through holes 26 for fixing this receiver assembly member 11 on a receiving beam 4 (for example by means of screws). These orifices 26 are here two in number, arranged along a longitudinal axis, on either side of the opening 20. The complementary assembly member 12 is described below in connection with FIGS. to 14. This complementary assembly member 12 also consists of a plate of generally rectangular shape, comprising - a rear face 30 intended to come into contact with the headboard 3, and - a front face 31 intended to come into contact with the The complementary assembly member 12 also comprises two front hooks 32 and 33. As subsequently developed, these upper hooks 32 and lower 33 are intended to engage with, respectively , the upper hooks 17 and lower 18 of a receiver assembly member 11 associated, for the mechanical connection between the two connecting members 11 and 12 associated (Figure 3) For this, the front hooks 32 and 33 also have a section in L, arranged one above the other on the same vertical axis to form an upper hook 32 and a lower hook 33, each of which delimits a longitudinal opening 32a and 33a opening here downwards (once suitably mounted on the insert 3). In other words, these hooks 32 and 33 each have a dihedral or angle form. To constitute these two hooks 32 and 33, the complementary assembly member 12 here comprises a rear wall 34, of generally rectangular shape and forming the rear face 30 of this assembly member 12. The front wall 34 is delimited - by an upper edge 34a, - by a lower edge 34b and - by two lateral edges 34c. It also comprises a front face 34d and a rear face 34e (corresponding to the rear face 30 of the assembly member 12). This rear wall 34 is extended along its length along each of its two lateral edges 34c, by a longitudinal lip 35 projecting forwards.

The internal faces opposite these lips 35 are separated by a distance F which is slightly greater than the first distance E separating the external faces of the longitudinal lips 25 carried by the receiver assembly member 11.

This dimensional characteristic allows a positioning with a certain lateral clearance and optimal guidance of the complementary assembly member 12 on its receiver assembly member 11. The upper hook 32 is constituted by two rectangular wings 32b and 32c carried here by the longitudinal lips 35, namely - a horizontal wing 1 o 32b, here constituting the upper transverse border of this complementary assembly member 12 and extending perpendicularly to the rear wall 34, and - a vertical wing 32c. The bottom hook 33 is also constituted by two rectangular wings 33b and 33c, namely - a horizontal flange 33b, extending forwardly from the rear wall 34, and - a vertical flange 33c. This lower hook 33 is located here between the lower edge 34b of the rear wall 34 and the upper hook 32. The vertical wings 32c and 33c extend downwardly their respective horizontal flanges 32b and 33b, extending in a plane shifted towards 20 the front relative to the plane passing through the rear wall 34 of the complementary assembly member 12 (that is to say, still in a plane shifted forwards with respect to the plane passing through the rear face 30 of said assembly member 12). As illustrated in FIG. 14, the lower hook 33 is centered on the median longitudinal axis of the assembly member 12 and its width G is smaller than the distance F separating the internal faces facing the longitudinal lips 35. , so as to define two lateral grooves 36 for positioning on the receiver assembly member 11. The width of each of these lateral grooves 36 is slightly greater than the width of the longitudinal lips 25 equipping the receiver assembly member 11 to allow lateral play of assembly. FIG. 13 also shows that the inner face of the vertical flange 33c of the lower hook 33 has a transverse rib 33d intended to be housed in the complementary groove 24a fitted to the lower hook 24 of the receiver assembly member 11 .

The front wall 34 also has through holes 38 for attachment of this complementary assembly member 12 on the headboard 3 (for example by means of screws). These orifices 38 are here two in number, arranged along a longitudinal axis, on either side of the lower hook 33 mentioned above. In practice, firstly, the receptor assembly members 11 and the complementary assembly members 12 are attached, respectively, to one of the longitudinal members 4 of the bed frame 2 and to the headboard 3, such that The two receptacle assembly members 11, like the two complementary assembly members 12, are separated from each other by the horizontal distance A above. The receiver assembly member 11 is oriented so that its hooks 17 and 18 open upwards, and the complementary assembly member 12 is oriented so that its hooks 32 and 33 open towards the low. Then the headboard 3 is brought into horizontal translation towards the bed frame 2, so that the complementary assembly members 12 cover the receiver assembly members 11. In this configuration, the hooks 32 and 33 of each member 20 complementary assembly 12 are positioned, respectively, directly above the hooks 17 and 18 of the associated receiver assembly member 11. For this, the lower hook 33 of the complementary assembly member 12 is introduced through the opening 20 of the assembly member 25 receiving 11. The assembly members 11 and 12 are brought together until that the front face 19d of the front wall 19 of the receiver assembly member 11 is in abutment against the front wall 34d of the rear wall 34 of the complementary assembly member 12. In addition, each member of FIG. complementary assembly 12 is locked laterally, while preserving a certain clearance, by its longitudinal lips 35 which are placed on either side of the longitudinal lips 25 equipping the receiver assembly member 11 associated. In this position, it is then sufficient to maneuver the headboard 3 in a translation movement downwards, so that the hooks 32 and 33 of the complementary assembly members 12 engage in the hooks 17 and 18 of their associated receiver assembly members 11. This maneuver is guided laterally by the longitudinal lips 25 and 35 vis-à-vis the assembly members 11 and 12, and is guided vertically by the front faces 19d and 34d resting on one another. During this maneuver, the vertical wings 32c and 33c of the hooks 32 and 33 of the complementary assembly member 12 are housed through the upper opening 17a and 18a of the hooks 17 and 18 carried by the assembly member. receiver 11 associated. 1 o The headboard 3 is properly locked against the front / rear games. For this, the thickness of the vertical flanges 32c and 33c of the complementary assembly member 12 corresponds, with the clearance, to the thickness of the longitudinal grooves 17a and 18a defined by the complementary hooks 17 and 18 (this thickness corresponds here at the distance between the rear face 19e of the front wall 19 of the receiver assembly member 11 and the front face 3a of the headboard 3). Likewise, the thickness of the vertical flanges 23 and 24 of the receiver assembly member 11 corresponds, with the clearance, to the thickness of the longitudinal grooves 32a and 33a defined by the complementary hooks 32 and 33 (this thickness corresponds to here at the distance separating the rear face of a vertical wing 32c and 33c and the front face 34d of the rear wall 34). The rib 33d of the lower hook of the complementary assembly members 12 engages in the groove 24a of the lower hook 18 25 of the associated assembly members 11 associated. These complementary structures of the kind rib / groove provide a removable locking of each pair of assembly members 11 and 12 (Figure 3). In this configuration, the headboard 3 is suitably associated with the bed frame 2, through the fixing device 2, to form the desired bed structure 1. In a kinematic variant for the assembly of the headboard 3, the latter is moved closer to the bed frame with a tilt back (from the bottom edge to the upper edge of said headboard 3). The complementary assembly members 12 are then also inclined backwards.

The free edge of the vertical flange 33c of the lower hook 33 of the complementary assembly members 12 is brought into abutment against the intermediate bottom edge 19h of the front wall 19 of the associated receiver assembly members 11.

This support is a horizontal axis of rotation, allowing a guide rotation of rotation of the headboard 3 to its vertical position. Once this vertical position is reached, it suffices to operate the headboard 3 downwards as described above to cause the engagement of the hooks 32 and 33 of the complementary assembly members 12 within the hooks 17 and 18 associated receiver assembly 11 (this vertical maneuver is naturally under the weight of the headboard 3). To separate the headboard 3 from the bed frame 2, it is sufficient for an operator to maneuver this headboard 3 in opposite direction, that is to say successively upwards, to clear the hooks 32 and 33 complementary assembly members 12 relative to the hooks 17 and 18 of the associated assembly members 11 and then in horizontal translation, to separate the complementary assembly members 12 relative to the receiving assembly members 11.

According to an alternative embodiment, the assembly members 11 and 12 described above can be inverted and returned to the bed frame 2 and to the headboard 3. The receiver assembly member 11 then becomes a member complementary assembly which is oriented so that its hooks 17 and 18 open downwards (the upper hook 17 becomes a lower hook); and the complementary assembly member 12 then becomes the receiver assembly member which is oriented so that its hooks 32 and 33 open upwards (the upper hook 32 becomes a lower hook). In general, the complementary assembly members 12 could be associated with any other item to be reported on the bed frame 2, for example another bed frame (to obtain twin bed bases) or a decorative longboard. Such fastening devices according to the invention thus make it possible to combine, on the one hand, a simple, fast and effective assembly of an element attached to a box spring frame, and on the other hand, an easy and safe disassembly of degradation.
