Definitions

  • the invention concerns a frame mounting method generally and more specifically a method of mounting at least one frame along the upper and/or lower edges of a spring carcass consisting of an assembly of spring pockets and intended e.g. for beds and the like, according to which method a number of spring-pocket lengths correspond ⁇ ing to the dimensions of the spring carcass in question are assembled to form the spring carcass, said spring- pocket lengths being formed by rows of juxtaposed pockets made from a gluable and/or weldable fabric or similar material, and by preferably metal springs arranged inside said pockets.
  • the frame is manufactured from a pre ⁇ ferably round or flat profile member of metal or plastics and the frame/frames are joined to the springcarcass by means of the springpockets that are positioned adjacent the upper and lower edges thereof with the aid of suitable metal staples.
  • the purpose of the invention is to reduce as far as possible the disadvantages and drawbacks outlined above and this purpose is achieved by the suggestion of a novel and unique method allowing spring carcasses to be manu ⁇ factured rapidly and efficiently at a competitive price.
  • the frame is made from a strip which is placed on the spring carcass along the upper and lower peripheral edges thereof and which is joined to the spring pockets positioned adjacent said upper and lower peripheral edges by means of gluing, welding or any simi- lar interconnection technique.
  • Fig. 1 is a perspective view as seen obliquely from above which schematically illustrates a spring carcass consisting of assembled spring pockets and on which car ⁇ cass frames have been mounted in accordance with the method of the invention.
  • Fig. 2 illustrates, on an enlarged scale, a portion of the spring carcass with the frames shown in sectional views essentially along line II-II of Fig. 1.
  • Fig. 3 illustrates, on an even larger scale, a first preferred embodiment of a frame shown in a sectional view essentially along line III-III of Fig. 2
  • Fig. 4 is a sectional view corresponding to Fig. 3 but showing a second preferred embodiment of the frame.
  • Fig. 1 illustrates, in a per ⁇ spective view as seen obliquely from above and schemati- cally, the spring carcass 1 generally designated by numeral reference 1 and consisting of an assembly of pocket springs to form a semi-finished product for the manufacture of mattresses to be used for instances in beds, sofas and similar items.
  • the shown spring carcass 1 is preferably made from an assembly of a plurality of pocket-springs lengths 2 the number of which (in the present case nine) corresponds to the size of the carcass, for instance 90 x 200 cm., which lengths are assembled side face against side face in a manner to be described more in detail further on.
  • Each pocket-spring length 2 in turn comprises a number, say twenty, of coiled springs made from wires of steel or other suitable material and arranged in rows and welded in position inside pockets 4 consisting of a glueable and weldable fabric 3, preferably a non-woven fabric or similar material.
  • a frame is to be mounted with the aid of the method suggested in accordance with the inven ⁇ tion. More precisely the frame 7 is manufactured, in accordance with the shown and described preferred embodi ⁇ ment, from a strip 8, which preferably is manufactured in the same material as the pockets 4, i.e. from a glueable and weldable fabric, preferably a non-woven fabric or the like.
  • each frame strip 8 is positioned on the spring carcass 1 along the upper and lower peripheral edges 5, 6 thereof and is joined to the spring pockets 4 positioned immediately adjacent the upper and lower edges 5, 6 by means of gluing, welding or with the aid of any similar technique.
  • the strip preferably is folded and the free edges 9 of the folded strip are joined together, see particularly Figs. 3 - 5, in a manner similiar to that used when joining the strip to the spring pockets 4, i.e. through gluing, welding or the like.
  • the frame strip may be used in a single layer condition or be formed by two or several superposed layers, not shown, the layers in the unit thus formed being interconnected along the free edges, also in this case preferably by means of gluing, welding or the like.
  • an elongate rein- forcement member 10 having a round profile configuration is enclosed inside the strip 8 and in accordance with another preferred embodiment, illustrated in Fig. 4, the corresponding reinforcement member 10 has a flat profile configuration. No separate reinforcement member is pro- vided in the third preferred embodiment illustrated in Fig. 5, a solution that might be of interest when the strip need not be particularly rigid.
  • a reinforcement member 10 In the embodiment comprising a reinforcement member 10 the latter preferably is manufactured from a compara- tively rigid material, such as rigid plastics or round or flat steel bars. Obviously, the reinforcement member 10 could be given a different profile configuration than round or flat, for instance an oval shape.
  • the gluing step is effected by application of a glue that is suitable for this purpose, such as hot melt, on the facing sides of the spring pockets 4 and/or the frame strips 8 in order to there form glue lines 11.
  • a glue that is suitable for this purpose, such as hot melt
  • the application of the glue is effected in a manner similar to that used when gluing together the spring- pocket lengths 2 as described earlier, by means of spray nozzles not illustrated.
  • the welding operation preferably is effected preferably but not necessarily with the aid of an ultrasonic welding head, not shown in detail, which head is arranged to be applied against a welding pad, not either illustrated, with inter ⁇ position between the head and said pad of the weldable fabric 3 of the spring pockets 4 and the strip 8 in order to form welding seams corresponding to the glue lines 11, to interconnect the spring carcass 1 and the frame 7.

Abstract

L'invention concerne un procédé de montage d'éléments d'encadrement (7) le long des arêtes périphériques supérieures et inférieures (5, 6) d'une carcasse à ressorts (1) réalisée par collage d'un certain nombre de longueurs (2) de poches à ressort, constituées d'une part, de poches (4) réalisé dans un tissu (3) pouvant être collé ou soudé, et d'autre part de ressorts disposés à l'intérieur desdites poches. Chaque élément d'encadrement (7) est constitué d'une bande (8) en matériau du même type que celui des poches à ressort (4). Les bandes (8) sont assemblées aux poches à ressort (4) placées de façon adjacente aux arêtes périphériques supérieures et inférieures (5, 6) de la carcasse à ressorts (1), par collage, soudage ou autre technique similaire d'assemblage.
