  • the component assemblies are attached to framework 11 by attaching the top of the peripheral springs with a plurality of attachment clips 18.
  • Attachment clips 18 are preferably about 1 inch wide and are formed from sheet metal. Finally, the top of the construction assembly is completed by a plurality of coupling wires 19 which interconnect the tops of the various springs to each other and to framework 11. Coupling wires 19 are preferably formed from high carbon 14-1/2 gauge wire.
  • FIG. 2 there is shown a bottom perspective view of the construction assembly shown in FIG. 1.
  • the construction assembly includes three identical component assemblies respectively designated 12, 13 and 14.
  • Each component assembly in this case referring to component 14, includes at its base an elongated closed wire frame 29.

  • the use of the term "hour-glass" with respect to the springs means that at least one intermediate coil is of a smaller diameter than the base and top coils. Hour-glass springs are preferred because the smaller intermediate coils have the ability to pass through the base coil and between support spars 20 and 21 when the furniture is supporting an extreme load. This ability prevents the furniture component assembly from being damaged due to permanent deformation when the load is removed.
  • Base coil 25 of spring 15 is connected to spars 20 and 21 by attachment clips 24, and top coil 26 is attached to framework 11 via an attachment clip 18.

  • Spars 20 and 21 can be thought of as being divided into four separate sections, namely forward section 32, transition section 33, middle section 34 and rearward section 36. The respective sections are separated by bends 30, 31 and 35 formed in spars 20 and 21. Bends 30* and 31 are of equal angles such that the plane defined by section 32 is parallel with the plane defined by section 34.
  • each component assembly such as component 14 shown, includes a short spring 15 attached at the forward section 32 and two longer springs 16 and 17 attached in middle section 34 of elongated frame 29. It is important to note that, for purposes of stability, the base coil of each spring defines a diameter which is substantially equal to the distance between the two spars 20 and 21.
  • Fig. 4 shows a top sectional view of a furniture spring construction assembly according to the present invention attached to the wooden base support 40 of a chair. The view is sectioned such that only the elongated wire frame and the base coils 50 of each component assembly 47, 48 and 49 is shown.
  • Wooden base support 40 has a front board 41, a rear board 42 and two side boards 43 and 44.
  • Base support 40 further includes cross support member 46, and is strengthened by corner braces 45 which are also preferably made of wood.
  • the various pieces of base support 40 are connected to one another by conventional means well known in the art, such as by gluing and/or by using screws.
  • the three component assemblies 47, 48 and 49 are arranged in a series between side boards 43 and 44.
  • Each component assembly has its forward section connected to front board 41 and its rearward section to cross support member 46 by brackets 55.

Abstract

L'invention se rapporte à un assemblage de ressorts pour meubles, qui est constitué par une pluralité d'unités constituantes. Chacune des unités constituantes comprend trois ressorts spiralés (15, 16, 17) espacés entre eux et montés sur un cadre fermé en fil métallique allongé, ayant la forme d'une boucle fermée de fil métallique présentant des première (32) et seconde (36) extrémités séparées par deux tiges transversales parallèles (20, 21). Les unités constituantes sont disposées en série et elles sont fixées à une structure en fil métallique (11) formant la limite extérieure de l'ensemble et placée sur les parties supérieures des ressorts périphériques. Les parties supérieures des ressorts spiralés sont reliées entre elles par une pluralité de fils métalliques de liaison (19) qui relient entre eux des ressorts adjacents.
