Definitions

  • the invention relates to a bed net with a springing system made up of ondulated cross springs anchored at an articulated frame supported by a supporting frame, said articulated frame presenting two or more sections acrticu- lated one to the other.
  • a bed net of this type is disclosed in FR-A-1 420 417.
  • this known bed net when two adjacent portions of the articulated frame and inclined one to the other so as to form - on the lying side or couch surface - angles smaller than 180°, a deforation of the springing system takes place, which determines a rise of the surface defined by the springs in the central longitudinal position of the springing system.
  • the object of the invention is a bed net of the above mentioned type which does not have said drawbacks, and particularly a bed net wherein the deformations of the couch surface are avoided regardless of the relative inclination of the sections forming the frame.
  • the bed net according to the invention is characterized in that in correspondence to one or more articulations of the articulated frame, there is provided a bar connected to the springing system and that the articulated frame is provided with stop elements, i.e. abutments apt to prevent the bar or bars from projecting above the lying planes defined by the portions of the articulated frame.
  • the bar is connected to the springing system in its intermediate zone, the end portions of the bar being not connected to the springing system. In this way, an elastic downward subsidence of the springing system is allowed, thus giving a better comfort.
  • the bar can be connected to the springing system by way of the hooks connecting two adjacent ondulated springs, the bar being provided with flat slots apt to be engaged by said hooks. In this way no additional connecting elements between springing system and bars are needed.
  • said slots can be provided on the portion of the articulated frame which is fixed with respect to the supporting frame.
  • said bar ends are able to move practically only along a line which is approximately at right angle to the mid portion of the frame.
  • said abutmens apt to prevent the bar from projecting above the lying planes defined by the portions of the articulated frame are formed by projections of the hinges of the relevant articulation, the bar being provided with corresponding recesses apt to cooperate with said projections. Said projections can be lined so as to reduce noise and mechanical stresses.
  • said projections with bushes of molded plastic material, said bushes being integrally formed with eyelets which embrace the corresponding ends of the bar. These eyelets form an elastic means apt to limit the spacing of the relevant bar from the hinges.
  • numeral 1 indicates a frame for supporting the bed net, while the bed net has one frame of its own in three parts; one part 3A forming the bedhead; one part 3B forming a central section fixed to the frame 1, and one part 3C forming the bedfoot.
  • the two parts 3A and 3C are apt to be variously raised from the lying plane parallel to the lying plane of frame 1 and thus relative to the part 3B.
  • the springing system is made up of a plurality of springs 5, with undulated wire in one plane, and transversally arranged, hooked to the longitudinal lengths of frame portions 3A, 3B, 3C by means of hooks 7 and each connected to the adjacent springs by means of hooks 9.
  • the outer springs are hooked, by small helical springs, to the frame transverse sides 3A, 3B, 3C.
  • the springs 5 make up a springing system typical of the owner production.
  • each section of the part 3B is connected to the support frame 1 at least through two brackets, at least one of them, designated by 10, forming also an articulation hinge of one of the mobile parts; in the drawing, the mobile part 3A.
  • Brackets 10 are, for example, welded to the frame 1.
  • the converging ends of the frame parts 3A, 3B to be articulated to the support bracket 10, have articulation ears 12, 14, respectively, which arise from the inside of the tubular section forming the frame portions 3A, 3B, this section having an inner lip 3X for the hooking of the hooks 7.
  • the pivot for the articulation of brackets 10, 12, 14 is designated by 16 and may be riveted or otherwise engaged.
  • the articulation axis between parts 3A and 3B of the springing system frame is transversal, since it is defined by pivots 16 located in alignement and opposite to each other onto the net.
  • a zone of the springing system corresponds where a cross-piece is applied, which prevents an upwards springing system curvature in the inclination arrangement of part 3A relative to part 3B.
  • the zone of the articulation axis defined by the pivots 16 corresponds to a space between two adjacent springs 5 and, thus, to a space in which hooks 9 connecting the two springs are aligned.
  • a bar or tubular cross-piece 20 is located below the springing system and is engaged with hooks 9 in an intermediate zone of the springing system width, except for the end lengths.
  • the bar or cross-piece 20 is connected to the hooks 9 through a flat slat 22 which is connected to the bar or cross-piece 20 through rivets or welding 24 and which is engaged to the springing system being embraced by hooks 9.
  • springs 5 in the articulation zone defined by pivots 16 are prevented from bending upwards by the bar or cross-piece 20 which is engaged to hooks 9; the springs may instead warp downwards as allowed by their end lengths which are not connected to the cross-piece 20, 22.
  • the bar or cross-piece 20 can be engaged with its ends into the slots 26 formed in relevant wings 28 welded at one of two parts 3A, 3B, and in particular at the part 3B which does not tilt. In this way, the ends of the bar or cross-piece 20 may lower by downwards springing system deformation but cannot raise beyond the boundary imposed by slots 26, below the axis 3X of the frame 3A, 3B, 3C.
  • the bar 20 stops against the upper bottom of slots 26 and prevents the springs from arching upwards in the articulated zone, the slots 26 acting as stop elements for the bar 20.
  • the springing system may sink down by sliding of bar 20 along slots 26. More simply, the bar ends can only stop against lips or wings 3X without needing a guide.
  • a bar 120 is shown similar to that indicated by 20, which, however, is connected by hooks 109 similar to those indicated by 9 but embracing the bar or cross-piece 120 to engage it in the lower part.
  • Fig. 9 a modified embodiment is shown of the bar which is supported by a T-shape section 220 having its wings connected to the ends of hooks 9.
  • numerals 51, 53, 55 and 57 indicate traditional components of the springing system which is anchored, by hooks 57 and others equivalent, to the inner lips 60 of a structure 62 some sections of which form the articulated portions of the springing system supporting frame.
  • a solid and stiff counterframe 64 may be combined for supporting the frame in its stretched arrangement.
  • Numeral 65 indicates arched cross-pieces which form strengthening struts.
  • the frame formed by the structure 62 comprises more portions A, B, C, E which are hinged one to the other by articulations 66, 68 and 70 according to the transversal axis through which said sections A, B, C, E may be mutually inclined - as indicated with A1, C1, and E1 in Fig. 11 - depending on the therapeutical and comfort requirements of the user.
  • Articulations 66 and 68 allow the formation of concavities turned towards the patient, whereas the articulation 70 allows the formation of a convexity turned towards the patient.
  • the articulations 66, 68 are made in a similar way as those provided in the previous example in order to achieve a limitation of the upwardly deformations of the springing system in the relative inclination arrangement and to consent a springing system subsidence.
  • the articulations like that designated with 66, have a pawl appendix, like 74 or 76 of the articulation 68 acting as stop elements, against which a bar or cross-piece 78 rests, said bar being engaged to the springing system 51, 53 remote from the ends which come in contact with the pawl appendixes 74 or 76.
  • a flat slat 80 may be provided, which is engaged to the bar 78 through rivets 82 or the like. To said flat slat 80 some of the hooking bridges 53 are engaged which are located between the adjacent springs 51.
  • the bar 78 may be tubular and may have a recess 79 at each end, such as is provided also for an equivalent bar 84 which extends in correspondence of the articulation 70; the bar 84 has also a recess 86 at each ends.
  • the recesses 79 are provided to contact with the appendixes 74, while the latter may be properly lined to avoid noise.
  • the sections C and E of the frame may be mutually inclined to form an upwards convexity as shown in the arrangement C1, E1, obtainable for the presence of the articulation 70.
  • the bar 84 engaged to the springing system at a distance from the ends.
  • the bar 84 is engaged to the springing system through hook-like bridges 53 and a slat 85 up to a certain distance from the frame.
  • the bar 84 must be susceptible of limit downward displacements only to avoid that in the arrangement of relative inclination between sections C1 and E1, an excessive lowering of the springing system takes place in the zone of the articulation 70.
  • one internal appendix 70A of each articulations 70 is coated with a flexible material layer 90 forming a bush to which a flexible eyelet 92 is combined, which is injection molded together with the bush 90 and capable of deflecting from a tension stressed arrangement, as shown in Fig. 17, to a flexed arrangement as shown in Fig. 16.
  • the bush-like part 90 serves for the contact with the recess 86 of the corresponding end of the bar 84, in the coplanar arrangement of sections C and E; yet the bar 84 may move away from the bush 90 through the deformation of the springing system under the limited load of the user's weight portion which weighs down on the net length where the user lies with his legs.
  • the lowering of bar 84 is limited by the extension of the eyelet part 92.
  • the springing system tends to lower in a marked way respect to the articulation axis 70, 70A.
  • This lowering is limited by limiting the spacing of bar 84 from appendixes 70A, for the presence of the eyelets 92; said eyelets, in fact, limit the displacement of bar 84 ends with respect to the articulation axis 70.
  • the presence of the components made of flexible plastics 90, 92 ensures noiselessness during each displacement or each conact.
  • the spacing of bar 84 from the appendixes 70A may take place either in vertical direction or in a direction slightly inclined towards the directrix of the angle formed by the two sections C and E.
