Definitions

• the present invention relates to a deformable device for holding and securing the end of one or more slats on the frame of a box spring or the like.
• This device acts as a mouthpiece and is associated with the frame of the bed base, either directly or indirectly by means of suspension members in particular.
• the end piece is made of plastic and, according to one of the embodiments, it is arranged in the form of a clip to allow the ends of the slats to be mounted from above while, according to the other more traditional embodiments, the ends of the slats are threaded into a cavity by deformation of said slat and / or of the end piece.
• This type of tip in the form of a clip, does not allow effective fixing of the end of the batten. Under certain constraints, the slat easily comes out of its housing.
• this device consists of a sort of clip made of high elastic memory material of the high density polyethylene type, such as for example the plastic material sold under the name "Hytrel”, and this clip consists of a sole or horizontal strip capable of being fixed in its central part, that is to say between its two ends, directly or by means of intermediate means, on the frame of the bed base, which strip has folds upwards, at its ends , in the form of hooks, which hooks envelop the sides of the slat and extend slightly on top of the latter, and, according to a preferred arrangement of the invention, the hooks extend over the top of the batten, over a distance of the order of 1 to several mm depending on the shore hardness of the material, preferably a distance between 2 and 3 mm. Still according to the invention, the hooks preferably have a section which is of lunar shape so as to avoid deformation at the level of the hook
• This clip-shaped device has the advantage, as in the case of the aforementioned patents, of allowing rapid positioning of the slat from above.
• the deformation and the shape of the clip in fact allow the batten to be introduced relatively easily from above thanks to an elastic spacing of the hooks.
• the shape of the hooks and their return on the top of the batten prevent the extraction of the batten by pulling upwards. The latter is held in place even under strong constraints, it can practically escape from the clip only by a translational movement, that is to say a movement in the transverse direction of the bed base.
• the flexibility of the clip is exploited for the installation of the slats, that is to say during the mounting of the slats on the bed base after having positioned the various clips acting as end pieces at regular intervals. This flexibility comes from the material itself and the thickness of the clip sole.
• the ability of the clip to resist the extraction of the slat also comes from the fixing of the clip, preferably on a part of its sole which allows a deformation such that, during an attempt to tear off said slat, the hooks tend to close and tighten and, therefore, to resist even more the said attempt to tear off.
• the clip-shaped device can be used alone as such, fixed by any suitable means on the long side of the bed base.
• This clip can be manufactured by extrusion and it is then presented in a unitary or in a bar form with fracture primers which allow them to be separated from each other.
• This clip can also constitute only part of a tip and be associated, in a single piece, with a base arranged to be fixed to along pan or whatever.
• the clip can also be associated with the base via an elastic member which can allow, conventionally, a vertical movement of said clip and also an oscillating movement for example.
• the clip-shaped device may comprise, on at least one of the internal faces of the hooks, a projecting retaining member cooperating with an appropriate arrangement on the sides of the batten to allow longitudinal wedging of this last. This arrangement may consist of one or more notches as required.
• the clip-shaped device has a wall which acts as a bottom for wedging the end of the slat transversely, which bottom can be shaped in the shape of a hook to improve fixing.
• This bottom can also be arranged from the sole of the clip, without being linked to the hooks.
• the device can comprise two clips associated in a single piece with the same base by means of elastic members, and this device can be supplemented by a general cap made for example of rubber-like material so as to form a nozzle with shapes and colors adapted to the needs, which cap has securing means constituted for example by a T-tab which is inserted between the adjacent hooks of the central part of the device and it also comprises a flexible skirt which covers and adapts to the contour of the clips and the contour of the wedging bottoms associated with the latter.
• the cap may consist of a horizontal plane provided on one side with a T-shaped tab and, on the other side, with a skirt which extends around the external periphery, which skirt is deformable and in particular retoumable at 180 ° to dress the hooks and wedging bottoms after installation of said tee.
• This type of cap has the advantage of being more convenient to produce by molding.
• the device consisting of clips associated with the same base by means of one-piece elastic members, has two clips linked together by horizontal arms which extend between the adjacent hooks located in the central part.
• these devices with two clips acting as a tip may include, at their base, a seat or cradle which can accommodate a third batten.
• the device consists of at least one simple clip for performing the longitudinal wedging of the end of a slat on the frame of the bed base, and the transverse wedging of the slat between the long sides of the frame is obtained by means of a complementary piece in the form of a sock threaded beforehand on the end of the slat with at least one orifice provided on its sides, to allow the assembly of the assembly on the clip, and in particular allow the passage of hooks.
• this sock can comprise, laterally, one or more orifices to allow the transverse setting of the slat in several positions and, these socks can be connected together and form a monobloc assembly associated with two slats, which can be mounted on two separate clips of the same tip.
• the invention proposes an arrangement of the sole which makes it possible to fix this tip on the frame of the bed base while allowing a slight tilting movement of said sole and the hooks in the event of significant deflection of the slats.
• the sole is extended from one of its edges, to form a flexible tab relative to said sole, which allows the device to be fixed by any appropriate means, of the horizontal staple or tenon type, which flexibility between said leg and said sole results from the adoption of a curved shape which is similar to a swan neck for the intermediate portion which connects the two.
• the fastening tab is located under the sole, in a position such that it gives, thanks to the shape of the intermediate portion and in addition to the tilting, a certain freedom of transverse movement for the toe cap. ie along the axis of the slat.
• the sole is partially cut in its central part so as to release a tongue, which tongue is fixed and secured by any suitable means, of the staple or vertical tenon type, to the frame of the bed base.
• the tongue has a thickness of between half and a third of the overall thickness of the sole, which sole is arranged so as to comprise over its entire bulk, only a thickness of almost constant material, close that of the tongue.
• a bottom acting as a stop for the end of the slat can extend from the sole, up to the level of the upper surface of the hooks, which bottom can, like the hooks, overflow on the top of the end of the slat, which is thus embedded.
• the bottom may include cutouts which make it possible to dissociate it from the hooks, which cutouts are interposed between the hooks and the bottom, arranged in a plane parallel to the end of the slat or else the cutouts are arranged in the bottom, perpendicular to the end of the slat, at the end of the sole for example, between the latter and the hooks.

• the grooves 81 extend, like the hooks 7, in the direction of the slats and form a kind of bridge, the outer feet of which are located substantially in line with the upper edge 10 of the hooks 7.
• This arrangement also makes it possible to maintain sufficient stiffness for the end piece, avoiding too much flexibility at the hooks 7.
• FIG. 34 shows an end-piece provided with a bottom 68 which acts both as a hook for the end of the batten and as a recess cavity thanks to a flange which is positioned on top of said batten.
• the batten is there also embedded in the end piece.
• This bottom 68 is free relative to the hooks 7 thanks to an absence of connection and material between the two. Cutouts 70 'obtained directly by molding, separate the hooks 7 from the bottom 68.
• the end piece whatever it is, has a bottom 16 or 68 in the form of a hook, a support and a locking of the batten are obtained which are sufficient and which in this case do not require having hooks 7 which truly extend over the batten.
• the hooks 7 of the clip part have only a role of positioning the slat relative to the long pitch and it is the bottom 16, 68 which, in addition to the transverse setting, ensures the maintenance of the slat.
• Figure 36 shows the deformation of the tip and in particular its tilting during a significant deflection of the slat 3.
• the tongue 76 which tongue retains the end piece by means of the beam 77 which provides the connection with the rest of the sole 6.
• this slat can be associated as shown in FIG. 21 in particular, with socks 50 which cover each of its ends.
• FIG 37 shows a clip-end which allows the fixing of two adjacent ends of slats located in the extension of one another.
• This clip-end has a base 82 which allows its fixing by stapling or by tenon.
• the central part of the sole has stops 83 which serve as a stop for the ends of the slats.
