I 11 Claims.
This invention relates to improvements in spring cushion structure The main objects of this invention are:
First, to provide an improved spring cushion structure in which the upholstery is effectively supported under yielding tension substantially throughout the surface thereof. a
Second, to provide an improved spring cushion have not attempted to illustrate the stitching or securing means.
The upholstery is directly supported by upwardly bowed zigzag auxiliary springs l4. These structure which is relatively yielding or soft and at the same time without permanent distortion.
Third, to provide a structure having the advantages stated in which the spring unit may be capable ofjsustaining loads economically produced and is one which may be easily upholstered.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.
A preferred embodiment of the invention is illustrated in the which: g
Fig. 1 is a plan view of a 'spring'cushion embodying our invention with portions broken away toillustrate various of its structural features and their relation, the base omitted. V Fig. 2 is a fragmentary somewhat enlarged sectionon line 2-2 of Fig. l.
Fig. 3 is an enlarged view partially in section showing further details of structure particularly in the matter of the relationship and connection of the parts.
Fig. 4 is a. fragmentary view partially in section on line 4-4 of Fig. 1.
In the embodiment of our invention illustrated, the bottom border frame I is of the tacking insert type provided with a fibrous insert 2 adapted to receive the retaining tacks 3 for the upholstery skirt 4. The upholstery designated generally by the numeral 5 is of the padded type, the padding accompanying drawing, in
or bottom frame being the fabric wardLy bowed position.
, iary springs are secured 6 being of cotton or other suitable material. The
Superimposed on the body springs is a fabric auxiliary springs N. are secured at their ends to thelon'gitudinal members I! as by means of the clips 46. The members ii are superimposed upon l2 and secured to the side members I! oftheborder. frame I. by means of clips I 8 arranged through the fabric I 2 so that the fabric constitutes a sound deadening means and is at the same time secured to the top border frame. v .This supports the springs l4 normally in their up- These auxiliary springs are connected at suitable intervals by means of the helical tie members l9, these tie members being engaged with the bight portions of opposed bends of adjacent spring members.
- The end auxiliary zigzag springs have helical spring connectors 20 secured to certain of their loops by means of the clips 2| while these helical connectors are connected intermediate the clips 2| to the border end members 22 of the border frame by means of the clips 22. These clips 23 are arranged through the pad or fabric l2 so that it is secured to the end members of the top border' frame.
With this arrangement, at least the end auxilin an outwardly inclined or canted relation as shown at 24 in Fig. 4 with the result that the ends of the cushions are suitably shaped or conformed-that is, is supported to provide a somewhat rounded or inclined end surface.
An upholstery supporting mat is superimposed on the auxiliary spring elements, this mat comprising a sheet of fabric 25 having a plurality of reinforcing strands 26 of resilient wire preferably rove therethrough as shown in Fig. 1, the ends of the strands being clamped around the longitudinal members 21 as shown at 28, Fig. 3. This mat has unreinforced border portions 29 which overlap or overhang "the top border frame ID. The spacing of these strands 26 is substantially less than the length of the reaches of the zigzag bends of the auxiliary spring elements so that they overlie these spring elements and are supported thereby and constitute effective supports for the upholstery which is superimposed on the mat, the upholstery being efl'ectively supported throughout. The mat also serves to transmit the' load eifectively to the auxiliary spaced parallel relation,
, being connected to flexible plurality of upwardly bowed springs and to which might be expected to arise because of the resilient character of the connectors II. This provides extreme resilience without likelihood of local collapse. In the event that the auxiliary springs should be completely collapsed vertically upon the covering loadis transmitted to a substantial number of the springs and of course the entire top of the superstructure is carried by the body springs.
with this arrangement of parts, we secure a structure in which the upholstery is effectively supported'against sagging. Tufting or piping of the upholstery may be dispensed with if desired and at the same time the upholstery is not likely to become displaced in use. The cushion presents a soft and yielding surface to normal loads but it is capable of sustaining heavy loads. The 'auxiliarysprings maintain the upholstery under tension at all times. Another advantage is that the upholstery may be applied very quickly and by relatively unskilled labor to the spring unit.
We have illustrated and described our improvements in an embodiment which we have found very satisfactory. We have not attempted to describe certain other embodiments it is believed this disclosure will enable those skilled in the art to embody or adapt our improvements as may be Having thus described our invention, claim as new and desire to secure by Letters Patent, is:
