Definitions

  • the present invention relates to a device for articulating slats on the frame of a bed and the method of manufacturing such a device.
  • slat articulation devices allowing the slats of a bed to pivot about an axis parallel to the transverse direction of the bed. Some of these joints can absorb a slight vertical displacement of the slat. However, even in the case where such articulations exist, this displacement is only due to the elasticity of the material used and does not allow, by an adjustment, on the one hand to modify the stiffness of the articulation element, d on the other hand to limit the downward movements of the batten.
  • a first object of the invention is therefore to propose an articulation device making it possible to modify the rigidity of this articulation as a function of the position of the latter on the slatted base.
  • This first object is achieved by the fact that the device for articulating the slats on the frame of a bed comprising at each end of the slat damping means with adjustable reaction force, is characterized in that the damping means are associated to means of articulation with each slat.
  • Another object of the invention is to propose an example of an economical and easy-to-assemble embodiment of the articulation device with an articulation on the frame.
  • the damping means are constituted by an element placed in a cage of the frame of the slatted bed situated at the location of each slat, this element comprising elastic means, each having the shape of a thick strip shaped in a zigzag shape and pressing, on the one hand, on the securing means at each end batten, on the other hand on a support plate mounted on adjusting means relative to the frame, the securing means comprising a branch parallel to each end of the batten and penetrating through an opening of the cage in the element.
  • the adjustment means consist of a screw comprising at the end of its thread articulation means on the support plate.
  • Another object of the invention is to propose a method of manufacturing the articulated frame.
  • the frame manufacturing process comprises a step of manufacturing frame rails provided at regular intervals with cages each accessible by an opening, a step of introduction into the opening of a support plate for length corresponding to the central part of the U of the second part.
  • Another object of the invention is to propose a method of manufacturing the side members of the frame.
  • Another object of the invention is to provide a frame whose shape is adapted to avoid a deburring operation of the cuts and injuries due to burrs on the edges of these cuts.
  • the method further comprises a step of folding inward the ends of the branches of the U of the piece forming a frame and a step of introducing at least one second piece through the end of the built.
  • Another object is to prevent the support plate of the elastic means and allowing the articulation from escaping from the cage.
  • the method comprises a step of bias introduction into the opening of dimension smaller than that of the cage of the support plates of length corresponding to the central part of the U of the second part.
  • the method comprises a step of compressing the elastic means for introduction through the opening into the cage and a step of placing the adjusting means.
  • the method comprises a step of introducing the connecting piece to the batten into the elastic means.
  • FIG 1 shows a first embodiment of a hinge device for a slat (1), consisting of a cage (2) integral with a beam (7) or frame (8) of a slatted bed.
  • a rod (3) articulated, for example, by a ball joint (30) in a housing (10) of corresponding shape made in the slat (1).
  • the rod (3) extending downwards by a plate (31) on which an elastic means (4) is supported.
  • This elastic means (4) presses at its other end on a second plate (5) movable in displacement in the cage (2) under the action of an adjusting screw (6) whose position can be fixed by means of a counter - nut ((60).
  • FIGs 2A and 2B show a second alternative embodiment of the joint according to the invention, in which a frame (8) forming the turn of the slatted base supports a frame (7) consisting of a U-shaped profile shown in Figure 6B.
  • This frame (7) has portions mounted rigid on the frame or pivoting to allow the constitution, in a known manner, of inclined planes at the head and at the foot of the bed.
  • the frame (7) has at the location of each slat an opening (70) whose axis of symmetry is parallel to the axis of symmetry of the slats.
  • each opening (70) is formed, in the leg (72) of the U of the part (7), a hole (73) allowing the passage of a screw for fixing the frame (7) to the frame in wood (8).
  • a cage is formed using a second U-shaped part (9), shown in FIG. 7A, and the ends of the branches of which are folded outward. to form side wings (90,91).
  • This second U-shaped piece has in the central part of the U a hole (92) provided with a thread for receiving a screw (6) for adjustment.
  • the second part (9), shown in FIGS. 2 and 6A, is joined to the first part (7) in the form of a U by welding points on the tongues (90 and 91).
  • the latter may comprise at the end of its branches (71,72) an additional folding of the latter towards the inside, so as to constitute the internal lips (720,710, Figure 6B).
  • This embodiment prevents the cutting edges from injuring the user.
  • each piece (9) of width corresponding to the thickness (e) of the central part of the U-shaped piece (7) is introduced at the end of the frame and slid to the corresponding location of the opening (70) near which it must be secured.
  • the support plate (5) has a recess or a hole (50) in which is housed a conical point (61) or a stud located at the end of the screw (6) for adjusting the stiffness of the joint.
  • This plate (5), of length greater than the length (L) of the opening (70) is placed in the cage, of length (D) greater than the length of the plate, by introducing it at an angle into the opening (70).
  • the elastic means (4) represented in FIGS. 3 and 4 consist of a molded part of suitable elastic material comprising a bearing face (42) on the plate (5), two lateral elastic elements (40,41) placed close by. faces adjacent to the sides of the part (9) constituting the cage and a second bearing face (43) coming to bear on the internal face of the central part of the frame (7).
  • the elastic elements (40,41) have the shape of a thick strip folded in a zig-zag.
  • the bearing surface (43) has an opening (44) of appropriate size and intended to receive the part (11) connecting with the slat (1).
  • the upper part of the bearing surface (43) has a lip (430, FIG.
  • This part (11) shown in Figure 4 also has a U-shaped section.
  • the branch (110) of this part is housed in the opening (44) while the branch (111) is housed in a blind hole integral with a part (12) whose shape is adapted to wrap the end of the slat (1).
  • This part (12) is made of slightly extensible material to ensure with the slat (1) a fixing by friction.
  • the U-shaped piece (11) has its branches (111,110) parallel to the slat and oriented towards the outside of the bedding so as to block the slats transversely to the frame, when the openings (70) are oriented towards the inside of the bed frame.
  • FIG. 5 represents a second mode of connection of the part (11) with a slat (1).
  • the connection is made by mechanical means such as a rivet (13) or a screw-nut assembly, not shown, or for example a countersunk head screw which is screwed into a threaded hole made in the branch (111) of the part. (11).
  • FIG. 5 also represents a variant in which the cage (2) enclosing the elastic means (4) is produced directly inside the wooden frame (8) of the bedding.
  • This embodiment makes it possible to produce only slatted bed bases not comprising no device for adjusting the inclination of the box spring at the head and at the foot of the bed.
  • FIG. 6C represents a part of the method of manufacturing the frame from a strip (7) of width corresponding to the dimensions of the deployed U.
  • this strip (7) the openings (70) are cut out at the desired locations by cutting using a tool and then this strip is folded along the two dotted lines (73,74).
  • the line (74) passes inside the openings (70) so that the edge (700) of the cut is slightly recessed, as shown in Figures 4 and 6B, relative to the face corresponding to the leg (71 ) of the U. This withdrawal makes it possible to avoid the friction of the part (11) against the edge (100) and consequently the operating noises of the bedding.
  • the manufacturing process is optionally continued by two other folds constituting two lips (720, 710) turned towards the inside of the profile to avoid injuries.
  • a second part (9), constituting the lateral sides of the cage, is assembled with the part (7).
  • This operation on metal parts can be carried out by welding the tabs (90, 91) on either side of the opening (70).
  • the second parts (9) are also obtained by cutting and folding a strip of width (1). Similarly before the operation of bending the piece (9) in a U, a threaded hole will have been made in the zone corresponding to the central part of the U. In the case where the profile (7) has the lips (720), the parts (9) by the end of the frame.
  • the pieces of frame thus formed are cut to the appropriate dimensions making it possible to constitute either rigid bed bases or bed bases with articulated head and foot and mounted on each side of the bedding frame. Prior to mounting the frames on the bedding frame, the constituent elements of the joint will have been placed in each portion of the frame.
  • FIGS. 8A to 8D represent another embodiment of the joint.
  • the same references have been kept to identical parts and only the modified or added parts bear new references.
  • the part (9) constituting the sides of the cages has a central part (93) deeper than the depth of the elastic part (4).
  • This part (9) has two additional lips (94, 95) obtained by folding along a plane perpendicular to the branches of the U and to the central part (93). These lips (94, 95) hold the elastic means (4) against the face (71) of the frame (7).
  • the lip (430) of the elastic means (4) prevents friction of the part (11) on the frame (7).
  • the upper branch (111) of the U-shaped connecting piece (11) has two teeth (111A and 111B) which slide into the grooves (172, 173) of a fixing piece (17) whose cross section has the shape of a T.
  • This fixing piece (17) is secured by any means at the end of each slat so as to have the axis of symmetry of the grooves (172, 173) parallel to the axis of symmetry of the slat (1).
  • a screw (14) with a sunk head passes through a hole (170) provided with a chamfer (171) of the fixing piece and is screwed into a washer washer (16) with claws (160) which is embedded in the wood of the slat (1).
  • Each nut (16) is covered with a cap (16) to improve the finish of the batten (1).
  • the elastic elements (40, 41) allow the vertical movement of the slat (1) via the connecting piece (11) but also a rotation or articulation of the slat (1) by a difference in deformation of one element (4o) and relative to the other (41), respectively (41) relative to (40).
  • the assembly of the parts (7) and (9) constituting the frame made of metallic material or not can be carried out by any process other than welding.
  • the frame can also be constituted by a single molded piece of thermosetting material and provided at regular intervals with openings (70) forming the cages intended to receive the other elements of the joint, namely, the support plate (5), the means elastic (4) and a nut washer forming the thread for the adjusting screw (6).
  • the openings (70) of the cages can be turned towards the outside of the frame and in this case, the fastening pieces (11) will have at least the leg (110) parallel to the slat and turned towards the inside. of the bed frame.
