i 2 Claims. l
-. This. invention relates .to improvements .in springvzassemblies forupholsteryand has for its main object to provide simple and eflicient means for cennecting. all of. the springs of the structure with each other" and. marginal. frame.. members and utilizing said connecting. vmeansto .connect devices .with said marginal frames which. bridge the terminal coils of alLof the component springs of ..the assembly; .thereby to prevent .ba'ttsi or. pads of'fibrous materials covering the faces "of'said assembly when the latter is incorpor'ated'in a mattress orncushion from projecting appreciably into the end 'portionsof said component springs.
A further objectof theinventionis to so associate the meansconne'cting'thesprings with each otherrwithmaid spring bridging. meanssasi toi-maintain the latter held firmly againstrlateral displacement relative to springs bridged thereby without resort-to the use of any meansconnecting saidibridging elements with said spring'and' marginal frame connecting means. 7
:Anothepobject of the inve-ntiomis to" provide bridgingmeans additionally tothose which'bri'dge thenend coils of said springs,.-for=-bridging open spacesiincthe assembly borderedgiby thei' 'outer peripheral surfaces of the terminal coils of the component springs of the assembly which are similarly connected with said marginal frames and the spring connecting means as are those which bridge the terminal coils of the said springs.
Suitable embodiments of the invention are illustrated in the accompanying drawings wherein:
Fig. 1 is a plan view of a spring assembly constructed in accordance with the invention.
Fig. 2 is a vertical sectional View taken on the line 2-2 of Fig. 1.
Fig. 3 is a fragmentary vertical detail sectional view, on an enlarged scale, taken on the line 3-3 of Fig. 1.
Fig. 4 is a fragmentary plan view of a modified form of embodiment of the invention.
Fig. 5 is a fragmentary detail vertical sectional view taken on the line 5-5 of Fig. 4.
In the art to which the invention relates, spring assemblies of the type illustrated in Patent #2,124,695, are varied with respect to the total number and diametric dimensions of the terminal coils of the conventional hour-glass type of upholstery spring employed, to vary the production costs of the assemblies proportionately to the number of springs of which said respective assemblies are composed, the shapes of said terminal coils of said springs being also varied.
Thus, for example, a spring assembly of standard double bed size, composed of large diameter springs may containlten longitudinally disposed parallel ..rows of. springs .whichlarehspaced i only slightly Jspaced .apart the .numberlof springs-of each .row. being. determined, -ofm .co'urse by lithe length ofithe assembly. and. the diameters .of.;the terminal coils of the springs.
Obviously, ifthe assembly. of; given size :isicomposedv of a -smaller number OfrSELid. rows. of. springs, the latter are spaced. farther-apartandathusthe assembly presents relatively. large..:.area open spaces betweenrsaid. rows :intouwhichias .wellias into. rthe rends oflthe springsi the saiditbatts .or padding .will project. 7
All of the springs "of the severalzrowsnthereof areoonnected with each and with: -the=.-adiaoent rows and. thelmarginalirames by meansofaconventionalhelical-.tie-wires which bridge the spaces betweenathe rows of,springs.,.-.and\ saidrtie-lwires bridge the largest area spaces tbetweenlsaiderows.
..The framemembers m ay:be composedaofuoonventionalround =wire-inr place; of the iiatwwire type of .the-aforesaidapatent and-'shoWn in Hthe accompanying drawings orz of: wire-.ofwany-other cross-sectional shape. andgin -somer-instances', they may be composed only of helical r-wirerengaged with the outermost portions of the terminal coils of the marginal springs of the assembly, the plan views illustrated being top or bottom alike.
The conventional helical tie-wires 3 of Fig. 1 extend transversely of the rows of springs l, conventionally, but do not extend to the marginal frame members 4, nor are they engaged therewith or with the helical tie-wires 5 which connect all of the marginal springs I with said frame members 4. The terminal coils of the tie-wires 3 are distorted conventionally to form closed loops which prevent disengagement of said tie-wires from the springs I Which they join.
The bridge elements or members 2 are composed, preferably, of resilient wire which may be flat or round, the flat type being preferred, and are equipped with substantially L-shaped terminals which present arms 6 extending at right angle to the body portions.
The body portions of said members 2 extend through coils of the tie-wires and, in most instances, extend diametrically of the springs l of the several rows of the latter that are joined by said tie-wires, the arms 6 of said members 2 being engaged in several coils each of the tie-wires 5 of the frame members 4.
It is immaterial whether the body portions of the members 2 are disposed outwardly or inwardly of the terminal coils of the springs I, because, first, they are composed of small gauge wire, round or flat; and thus are of less width than the length of the coils of the tie-wires 3, and, when passed through the latter, they are free to move laterally to only a very limited degree. As shown in Fig. 5, the wires 2 may pass under overlapped end-coil portions of springs I and then over the next adjacent overlapped spring portion, or as shown in Fig. 4, they may extend only over the terminal coils of all springs I of a row.
The terminal end portions of said members 2 may be bent, to the L-shape form shown, at one or both ends after they have been threaded into place relative to the springs I and through the selected coils of the tie-wires 3, before the frame members 4 are secured in place by the wires 5, the terminal arms 6 being disposed upon the frame member 4 before the latter are secured to the said marginal springs I, in the preferred embodiment of the invention.
The above described method of effecting assembly of the structure may be varied, however, as by the provision of means, in an assembling equipment, whereby the members 2 equipped with arms 6 are maintained in bridging relation to rows of springs I while the tie-wires 3 are being disposed in encircling relation to the terminal coils of said springs I, thus to cause said tie-wires 3 to also encircle the members 2 at their points of bridging the encircled portions of the springs I.
The members 2 of Fig. 1 which are disposed between the rows of springs I may be omitted, and are omitted in instances, such as shown in Fig. 4, wherein the said rows of springs I are spaced apart only slightly.
As shown in Fig. 4, the springs I of every row may be bridged by a plurality of said members 2, and in all instances wherein the springs I and tie-wires 3 are assembled prior to the addition of said members 2, the latter, as straight strips, devoid of the terminal arms 6, may pass over and underneath the terminal coils of the springs and through the proper coils of the tie-wires 3, and the ends of said members 2 bent to hook formations 1 engaged with the frame members 4 as shown in Fig. 5.
I claim as my invention:
1. A spring assembly comprising a series of parallel spaced apart rows of upholstery springs, helical tie-wires extending transversely of said rows and joining all springs of all of said rows, resilient border frames disposed marginally of all marginal springs of the several rows of the latter, resilient flat wires bridging all springs of each row axially of the same and equipped with terminal flanges overlapping and disposed in surface contact with the border frame, the width of said flat wires being no greater than the length of coils of said tie-Wires and being secured by the latter to overlapped terminal end-coil portions of the springs, encircling and joining the springs of the several rows of the latter, the end-coils of the springs of each row and end-coil portions of the springs of the outermost rows thereof being disposed in overlapping relation to the border frames, and helical tie-wires encircling said border frames, the flanges of said bridging wires and the portions of the springs overlapping said border frames.
2, A structure, according to claim 1, wherein the border frames and the said bridging wires are composed of flat wire and the flanges of said bridging wires overlap the outer faces of said border frames and the end-coil portions of all marginal springs overlap the inner faces of the border frames.
