Definitions

  • the invention relates to an injection molded part made of an elastomer Support element for upholstery, especially for ventilated ones Upholstery pad like upholstery.
  • Mattress or the like of seating or lying areas, that can be attached to a base with a base is, has a cushion-receiving platen, in which between Base and platter at least two starting from the base Spring elements with leaf spring-like support arms (12; 22) in the direction the effective bearing force directional travel, their respective outer ends open into the support plate, are provided; it concerns also a bed system built on such support elements.
  • a frame for reclining or seating furniture, its longitudinal and cross bars are provided with easily mountable spring elements, describes the DE 196 37 933 C; these spring elements support support plates to which the mattress or a cushion rests.
  • the spring elements are formed by lying leaf spring elements, which are approximately C-shaped mirror-symmetrical to each other so arranged are that the lower leaf spring is supported in the center of the spar and the upper leaf spring supports the support plate in the middle.
  • GB 2 143123 describes a movable pad for upholstery or the like, in which a number of annular connecting members by means of Clamping bodies are interconnected. Such a document is stable in itself through the connection and does not require any additional pad, the mobility of the pad in however, no force-coordinated support is allowed.
  • One of individual support elements with at least the base and platter do not describe either.
  • DE 295 05 052 U describes a support element, at which is a cross lattice of intersection pieces and arms is formed, wherein on the crossing pieces and / or the arms spring body with the head side attached support plates are clipped on.
  • the Lock parts designed differently, a mere putting on the Plates on the base are not possible.
  • At least three or four support arms directed outward from a base provided that act as leaf springs in the direction of the Contact force directed spring travel are formed.
  • On each of these Support arms are provided with a support surface at the end; this Support surfaces of a support element together form the cushion receiving support plate to which they are between the support surfaces in the Area of bridge connectors are attached. These contact surfaces are pushed outwards when the springs are pressed through. With others Spring elements are now coupled to these contact surfaces so that the Outward movement spans these additional spring elements.
  • These support arms are arranged rotationally symmetrically; so the Angular distance from three support arms 120 ° and from four support arms Is 90 °.
  • Leaf springs are designed so that their spring constants are the same, there is also a lowering without lateral force components (that known from other upholstery elements) "tilting” so that a proper Padding is achieved; it goes without saying even that the spring constant is selected independently.
  • the platter by appropriate training of the Contact surfaces an inner free space, at least the size of the base, spring travel can be achieved, which - apart from the material thickness - The height of the support element itself correspond, so that this lowering can even take place to the level of the base.
  • the support arms delivering the spring force from a corresponding high-quality elastomer the contact surfaces are made from economical plastics: such double plastic articles can be sprayed using the two-component process or manufacture in change machines.
  • the Base designed accordingly: Should height differences in the attachments be balanced so that all support plates in one Level, the base is advantageous as a base plate or as a base body appropriate height trained. With an apprenticeship provide the base plate / base body with a central hole. Here is attached with a screw or with a dowel, whereby Penetrate screw or dowel into the base. In an analogous way the base plate is provided with two holes or dowels that are covered diametrically opposite each other on the center of the base plate. It is also fixed here using screws or dowels; this is because of the screwed or dowelled connection the hole arrangement secured against rotation.
  • Is on the pad T-shaped bracket attached has the central hole for secure attachment with overlap of this holder at least one, preferably however two flattened sides arranged opposite each other on.
  • the flattening can be used to attach the T-shaped holder be applied to the pad;
  • the support element is then put on and fixed by turning about 90 °.
  • the base plate has hook-shaped strips on; these strips are included on the base Holding elements together so that the hook-shaped strips with corresponding Interlocking projections on these holding elements form a positive connection.
  • these hook-shaped Moldings are elongated and on both sides of the center of the base plate arranged, they form part of a sliding connection, whose other.
  • Part of the holding elements provided on the base form so that the support elements on such holding elements can be postponed; at curved and diametrically opposite each other strips arranged with respect to the center of the base plate they form one part of a screw cap, the other part formed by correspondingly provided on the support elements become.
  • the support elements are here in the manner of a bayonet Twist lock can be screwed onto the holding elements.
