Definitions

  • the invention relates to a reversible head or foot switch in an upper position with a plurality of step catches for pivotable frame parts such as mattress frames, consisting of a / U-shaped toothed rail, the articulation end of which can be detached from two angles on a lower fastening element fastened to the wooden or tubular steel frame is pluggable, a one-piece, partly U-shaped carrier with two articulation struts, the elastic articulation ends of which can be clamped with outwardly projecting bearing pins into an upper fastening element from two angles with rotary openings, a swivel joint for connecting the joint end of the toothed rail to the joint end of the carrier and a support strut articulated to the support, the detent end of which interacts with the respective detent toothing in the individual detent stages, and with a slide as a control element for the detent-free return of the head or foot switch to its initial position.
  • pivotable frame parts such as mattress frames, consisting of a
  • the head or foot plate was connected to this frame part before the completion of the frame by means of a fastening element which was firmly riveted or welded to the corresponding frame part.
  • the head or foot switch had to go through the production line for the assembly of the frame, which had disadvantages. It was not common to design the fastening elements and the articulation ends of the head or foot plate so that the fastening elements could be firmly connected to the corresponding frame part before the frame assembly and could be combined with the head or foot plate after passing through the assembly line.
  • an upper fastening plate for a head or foot plate consisted of two angles and a base plate, which was fastened to the movable frame part.
  • the corresponding articulation ends of the support of the head or foot plate had pivots, which could easily be inserted into the rotary openings of the angles of the mounting plate due to the elastic design of the articulation ends.
  • the lower mounting plates for hanging the racks had spaced flat swivel pieces, which were only connected on one side to the lower mounting plate.
  • the corresponding swivel openings on the articulated ends of the toothed rails could be pushed sideways onto the free end of the swivel piece.
  • Such mounting plates for articulating the head and foot plates on the mattress frame or on the movable frame parts are in need of improvement.
  • the lower fastening plates for the toothed rails are susceptible to the bending moments that are constantly exerted on the swivel pieces with an acceptable material and fastening effort.
  • the lower mounting plates tended to loosen or bend over time, so that proper articulation of the toothed rails on the mattress frame was permanently disturbed.
  • a head or foot divider with a plurality of step catches has also become known, according to the preamble of independent claim 1, in which the lower fastening element has two angles and the upper fastening element consists of two angles with rotary openings, the elastic articulation ends of the carrier having outwardly projecting bearing journals (EP-A-0 291 840).
  • the object of the present invention is not only to improve the stability of a head and foot plate of the type described above, but also to improve the safety and rigidity of its fittings which improve the mattress frame or the movable frame part with the scarcest use of materials .
  • the lower fastening element includes a flat pivot piece arranged between the two angles and the legs of the articulation end of the U-shaped toothed rail include articulated openings provided with a slot, such that the articulation struts of the carrier L- shaped inwardly bent upper stiffening edges and the angles of the upper connecting element slip channels to the rotary openings for the outwardly projecting bearing pins on the pivot ends of the carrier, and that the slide is guided within the U-shaped toothed rail in longitudinal beads, which at the same time stiffening beads for the toothed rail are.
  • the toothed rail and the support of the head or foot plate according to the invention are inherently load-resistant in any direction with relatively thin sheet metal.
  • the lower fastening element designed according to the invention withstands high permanent loads.
  • the flat swivel is securely attached between the two angles of the fastener, which in turn are firmly connected to the frame.
  • the articulation openings of the toothed splint have slots which are directed in such a way that the toothed splint can be easily plugged onto its lower fastening element.
  • the slide is arranged as a control element for restless return within the U-shaped toothed rail. It is guided in longitudinal beads that point outwards, which are also stiffening beads for the toothed rail.
  • the upper and lower fastening elements can be fastened to the frame or to the frame parts by means of single-hole, multi-hole or U profiles, regardless of whether frame or frame parts made of wood or metal tubes are used.
  • FIG. 1 a), 1 b) and 1 c) show an overall view of a head or foot switch which can be reversed in an upper position and has a plurality of step catches for pivotable frame parts such as mattress frames.
  • the head or foot plate 1 can connect a pivotable frame part 2 made of wood or metal tube 3 to a mattress frame 4 or metal tube 5.
  • the head or foot plate 1 consists of a toothed rail 6, which in the preferred exemplary embodiment is U-shaped and has a leg 7 with an upper longitudinal edge 8 and locking teeth 9 arranged therein, and a leg 14 with an upper longitudinal edge 15 and locking teeth 16 provided therein .
  • Both legs 7 and 14 have articulation ends 10 and 17, in which articulation openings 11 and 18, each with a slot 12 or 19, are arranged.
  • the legs 7 and 14 each have a longitudinal bead 13 or 20 and are connected to one another by a base 21 in which a longitudinal slot 22 with stiffening edges 23 or a longitudinal bead is provided. Both serve to stiffen the U-shaped toothed splint 6.
  • the toothed splint 6 also has a hinge end 25 which forms part of a swivel joint 56, through which the hinge end 45 of a carrier 43 is connected via a swivel pin, not shown.
  • the carrier 43 consists of a substantially U-shaped part 44 to which two articulation struts 46 and 50 are connected. Each articulation strut 46 or 50 has an inwardly bent stiffening edge 47 or 51.
  • the articulation struts 46 and 50 end in articulation ends 48 and 52, each with a bearing journal 49 and 53.
  • Stiffening beads 54 are provided in the articulation struts 46 and 50, and a stiffening bead 55 is provided in the bottom of the U-shaped part of the carrier.
  • a support strut 57 with a latching end 58 is provided between the toothed rail 6 and the carrier 43 and is operatively connected to a slide 59.
  • the latching end 58 of the support strut 57 snaps into the corresponding latching teeth 9 and 16 in the latched positions of the head or foot plate.
  • the slider 59 is designed in a manner known per se so that when the head or foot actuator is returned in its rest position, the detent end 58 can move freely above the detent teeth 9 and 16.
  • the slide 59 is enclosed by the upper longitudinal edges 8 and 15.
  • the slider 59 as can be seen above all from FIG. 1 c), is also guided in the stiffening beads 13 and 20 of the toothed rail 6, which give it additional stiffening.
  • 4 a) to f) show different designs of lower fastening elements 27 for the toothed splint 6 on the mattress frame 4 and 5.
  • the lower fastening element 27 consists in its basic structure of two angles 28 and 29 which are connected to one another by a flat swivel piece 30 are.
  • 4 c) to f) show how this basic structure of the lower fastening element 27 can be fastened to the mattress frame 4 or 5. In the simplest case, this can be done by a two-hole profile 31, to which the two angles 28 and 29 are attached.
  • angles 28 and 29 can also be fastened to the mattress frame 4 and 5 by multi-hole profiles 32.
  • upper fastening elements 35 which likewise consist of angles 36 and 37, in which rotary openings 38 are provided.
  • slip channels 39 lead to the rotary openings 38, through which the bearing pins 49 and 53 on the articulation ends 48 and 52 of the articulation struts 46 and 50 move.
  • slip channels 39 make it easier to connect the carrier to the associated upper fastening element 35, especially since the articulation struts 46 and 50 have a not inconsiderable inherent rigidity due to their inwardly bent stiffening edges 47 and 51.
  • the slip channels 39 can also run from “outside” to "inside”.
  • the upper fastening elements 35 with their angles 36 and 37 can be made using single-hole profiles 40 (FIG. 5 d), FIG. 5 e)) multi-hole profiles 41 (FIG. 5 b) and FIG. 5 f)) and U-profiles 42 (FIG. 5 c) and 5 d)) are hinged to a pivotable frame part 2 or 3.
  • FIG. 1 and 3 show that the hinge end 45 of the carrier 43 is bent towards the swivel joint 56 towards the hinge end 25 of the toothed splint 6. This takes place at the end of the manufacturing operations of the carrier, the basic contour of which is first punched out of a blank and then bent step by step to the shape shown in dash-dotted lines in FIG. 3 b). Only when the deformation has ended by then is the hinge end 45 in a last operation 3 b) "after In the process of producing the carrier 43, its articulation struts 46 and 50 - as shown in FIG. 3 a) - are also bent outwards into the dot-dash position in order to have a sufficiently large prestress in the upper fastening element 35.
  • the slots 12 and 19 are inserted in the articulation openings 11 and 18 on the flat pivot pieces 30 of the lower fastening elements 27.
  • This swivel connection between the lower fastening elements 27 and the toothed rail 6 is secure because of the angles 36 and 37 and their fastening to the mattress frame even under permanent load.
  • the direction of the slots 12 and 19 is chosen so that in the normal position of the toothed rail a falling apart of these connectors is impossible.
  • the plug connection between the bearing pins 49 and 51 at the articulation ends 48 and 52 of the articulation struts 46 and 50 of the carrier 43 is just as secure. Without the stiffening edges 47 and 51, the manual handling when inserting the bearing pins 49 and 53 into the rotary openings 38 of the upper would Fastening elements 35 would be simpler, however, the rigidity of the head or foot plate 1 would suffer considerably.
  • the slip channels 39 to the rotary openings enable the carrier to be easily connected to its upper fastening element 35 with considerable rigidity of the carrier 43 as a result of the stiffening edges 47 and 51.
