Definitions

  • elastic spring insertions in this application means sets of elastic springs, combined within a frame or the like, so that they may be mounted in elastic spring bottoms in beds, chairs, sofas or the like.
  • Such elastic spring insertions are therefore produced from a substantial number of elastic springs, usually but not necessarily of diabolo formed winding. These springs have, in their untensioned state substantial axial length, which causes a corresponding thickness of the elestic spring insertion.
  • This compression has hitherto taken place by stacking a number of elastic spring insertions, compressing them between two plates and then binding up each elastic spring insertion. It is extremely ditficult to bind up the insertions; experience has shown that the binding up will not be uniform, but rather the thickness of the compressed and bound up elastic spring insertion will vary, which disadvantageously influences the volume of storing and transportation.
  • the present invention relates to a method for first compressing elastic spring insertions and their binding then up in their compressed state.
  • the invention also refers to machine operated or manually operated means, whereby the above mentioned disadvantages are effectively done away with. Certain purely mechanical arrangements are required according to the invention, independently of how one executes the compression, and whether or not the binding up takes place manually or by machine in a completely automatic procedure.
  • the binding up takes place by means of two strings, which, by means of staples or the like are connected to each other in the inter-spaces between each couple of immediately after adjacent elastic springs and/ or within the interior of said elastic springs in the elastic spring insertion.
  • the two strings, bands or the like are thereby arranged to run continuously each on its side of the elastic spring insertion without being interwoven with each other.
  • the arrangement for the execution of this method contains a device for compressing the elastic spring inserice tions to a thickness suitable for binding them up, and a stapling machine, for stapling strings or the like which are placed on opposite sides of the springs.
  • the staples are applied between adjacent elastic springs and/or into the interior of these elastic springs.
  • This binding up preferably takes place by two strong strings, bands or the like, below as a matter of simplicity referred to as strings, being fed in parallel to the movement of the elastic spring insertion, one such string below and the other one above the compressed elastic string insertions.
  • the two strings are stapled between adjacent elastic springs and/or within the interior of each of the elastic springs or, for instance, of every second spring.
  • the staples should be sufiiciently strong to maintain the bound up elastic spring in its compressed state during storing and transportation, but sufliciently Weak to bend when sufliciently strong drawing forces are applied to the ends of the two strings, in order that the strings may become free from each other without breaking.
  • FIG. 1 of the drawings there is shown an elastic spring insertion in its uncompressed state
  • FIG. 2 shows a commonly used arrangement for compression and binding up of a number of elastic spring insertions, stacked upon each other.
  • FIG. 3 shows schematically a machine for causing compression and binding up of an elastic spring insertion according to the present invention
  • FIG. 4 shows an elastic spring insertion, which has been compressed and bound up according to the present invention in a first form of execution with staples between the elastic springs
  • FIG. 5 shows a second form of execution thereof with the staples in the interior of the elastic springs.
  • FIG.1 thus, shows three elastic springs at one end of an elastic spring insertion, only a part of which is illustrated.
  • the three elastic springs are held together by means of a frame 10, 11, within which the three elastic springs 12, 13, 14, shown in the drawing, as well as further elastic springs are provided. They are wound in diabolo form, and the two outermost turns have been bent to form closed circles.
  • the elastic spring insertion is difficult to pack and to transport, and it is therefore desirable, that it be compressed and bound up in its compressed state before transportation or storing.
  • the manfacturer or furniturer, or the upholsterer who will mount the elastic spring insertion into some piece of furniture, will first release the insertions; accordingly the insertions are compressed and bound rarely.
  • FIG. 2 The traditional method for compressing and binding up is shown in FIG. 2, wherein a number of elastic spring insertions 15, 16, 17, 18, 19, are stacked between two pressure plates 20, 2 1.
  • the pressure plate 20 may be stationary, whereas the pressure plate 21 is movable downwardly by means of a machine or, viceversa, the pressure plate 21 may be stationary, and the pressure plate 20 could be arranged to me moved upwardly.
  • means are provided to bind up the insertions.
  • the springs for binding up the borders have been tied together outside of the elastic spring insertions, usually at the edge of the elastic spring packet according to FIG. 2.
  • the elastic spring insertion When releasing the plates 20 and 21, to enable the elastic spring insertion to be used, one had only to cut oif one of the strings close to one of the knots, whereafter they could without any difiiculty be drawn out.
  • FIG. 3 One form of execution of the invention is shown in FIG. 3 in the form of a couple of endless bands 26, 27, each running over a pair of directional rollers 28, 29 and 30, 31, respectively. If needed, one can arrange one or more support rollers 32, 33 for each of the bands. Preferably at least one roller for each of the two bands, for instance, the rollers 29 and 31, is driven to move the bands 26 and 27.
  • the elastic spring insertion is fed between the two endless bands 26, 27 in the direction of the arrow 34 from a transportation table 35 and is thus successively compressed, so that it will have been compressed when it leaves the bands 26 and 27 between the rollers 28 and 30. It is there pressed between a couple of blocks 36, 37 in order to be bound up.
  • the binding takes place by means of a couple of strings 38, 39, which are suitably fed from a couple of storing rollers not shown in the drawing.
  • a stapling apparatus is provided, fed with staples, which will embrace the two strings 38 and 39, as shown in FIG. 4 and 5, where two such staples are shown at 40 and 41.
  • the stapling apparatus contains two tools 42, 43, the tool 42 containing a feeder device for the staples, whereas the tool 43 forms the cushion for bending the staples, so that they will rigidly embrace the two strings.
  • the strings 38 and 39 are 'fed for this purpose each over one set of directional rollers, which are in the drawing schematically indicated by means of the two directional rollers 44 and 45, from which the strings 38 and 39 run through channels 46 and 47, respectively, in the two tools the free ends being indicated by the numbers 48, 49.
  • the tools 42, 43 are guided in such a way, that they move simultaneously toward each other by substantially equal amounts.
  • the tool 43 is controlled by an eccentric disc 50, and the tool 42 by means of an eccentric disc 51 acting through a lever 52, so that the tool 42 will be displaced downwardly, simultaneously as the tool 43 is displaced upwardly.
  • tieing should be easy to resolve, which is effected by gripping one of the two free ends 48 and 49 and drawing them apart. For this reason the ends should be suificiently long in order that they may be mounted into some suitable tool or some suitable machine. Further, it is necessary that the strings not be twined around each other.
  • the staples should have a rigidity and tension to maintain the elastic spring insertion in its compressed 4 state against the tendency of the elastic springs to return to their uncompressed state, but that they will be flattened so as to release the strings, when an additional power is applied, caused :by drawing in the two free ends 48, 49'.
  • the strings must further have a rigidity which is sufficient, in order that they endure not only the tension from the compressed elastic springs in the insertion but also, in addition thereto, the power which is required when releasing in order to flatten out the staples by means of the strings.
  • the method according to the invention can be effected manually, using an equipment of the general kind, shown in FIG. 3, whereby one drives the elastic spring insertion step by step through the compression apparatus; and, while the electric spring insertion is stationary, the stapling apparatus applies a staple.
  • the method can also be eflected completely automatically by using a machine driving in synchronism the compression apparatus and the stapling apparatus 42, 43.
  • an elastic spring insertion contains a greater number of elastic springs, arranged in rows, perpendicular to each other. It is usual to combine the elastic springs included in each row in the one direction by metallic spirals, meshing into the closed outer turns of the elastic springs. These spirals thereby keep the elastic springes contained in rows, perpendicular to the level of the paper in FIGS. 4 or 5, such as indicated at 55.
  • the spirals thus, may bind together, for instance the left edge of all outer turns in one row of elastic springs, parallel to the axis of the spiral, with the right edge of the row adjacent thereto, as shown in FIG. 5, or possibly they may run with their axes diametrically over the outer turns of the elastic springs in one single row, such as indicated in FIG. 4. In the last mentioned case, the springs interlace between the turns of the spirals.
  • the spirals 55 are intended permanently to remain associated with the elastic springs, when they are mounted in a piece of furniture, Whereas the tieing strings 38, 39 are intended to be removed, before the elastic spring insertion is mounted into the piece of furniture.
  • a method for binding elastic spring insertions having a row of elastic springs in a compressed state comprising placing a string over the springs on one side thereof and placing a string over the springs on the other side thereof, and stapling the strings together at various points thereon to maintain said springs in their compressed states.
  • Apparatus for compressing and binding elastic spring insertions including a row of elastic springs, comprising means for compressing the elastic springs, means for placing a string over the springs on one side thereof and placing a string over the springs on the other side thereof, and means for stapling the strings together at various points thereon to maintain said springs in their compressed states.
  • said stapling means includes a first portion for feeding staples and a second portion for bending the staples around the strings, said portions respectively having feeder elements to feed the strings in place on the springs.
