12 Claims. (01. 155-131) This invention relates to improvements spring structures.

The main objects of this invention are:

First, to provide an improved spring structure having a top border frame which is effective in supporting the upholstery, efiectively resists stresses applied in a horizontal direction, and at the same time may be formed of light stock.

Second, to provide a border frame for spring structures which may be readily constructed in any desired outline for the purpose of supporting the upholstery or providing a cushion structure ofv desired shape, and at the same time one which may be readily applied to a spring structure.

Objects pertaining to details and economies of spring assembly are connected by the crossed helical tie members 3.

My improved border frame. comprises a con tinuous outer frame member! whichis formed 01 flat wire stock-disposed flatwise or with the.

flat sides hdrizontally. This outerframe member is conformed to support the upholstery in the desired outline.. An inner :borde r frame member. 5 is provided which is anarprmed of fiat wire stock disposed flatwise or with the flat sides horizontally. The outer frame member comprises a front portion '6,- rear portion 1 and the invention will definitely appear from the description to follow. The invention is defined in the claims. a j

A structure which embodies the features of the invention is clearly illustrated in the accompanying drawings, in which:

Fig, 1 is a fragmentary plan view of a springstructure embodying the features of my inventlon, the bottom frame being omitted and only a portion of the top frame illustrated.

end portionsl. The inner frame member comprises a fronif'portion 9 and end portions ill.- The rear ends of the end portions ID are deflected or bent outwardly at H and secured to the side portions 8 adjacent the rear ends thereof by means of the clips l2. 7

Corresponding portions of these inner and outer members-are arranged in spaced substantially parallel relation. They-are rigidly and fixedly connected by-the spaced strut or tie memhers I 3 which are ofsheet metal stampings and Fig. 10 is a fragmentary plan view of still another form or embodiment of my invention.

Fig. 11 is a section on line H-li of Fig. 10.

In the accompanying drawings the body springs i are of the helical type mounted on a suitable base including cross members 2. The base frame is not illustrated and only portions of the springs of substantial width so that they form effective strut or brace members which also have a tie action as well as a bracing action against wracking movement of the frame members. The ends M of these strut members are folded around the frame members into clampingengagement there-' with.

The strut members in the embodiment illustrated in Figs. 1 to 4 have oppositely disposed offsets IS in the side edges thereof whichprovide shoulders 16 in supporting engagement with the adjacent edges of the frame member see Figs.

2, 3 and 4. Overlapping portions of the strut members are preferably secured to the frame members as indicated at I I. This may be accomplished by providing the clamping ties with suitable prick-punch projections embedded in the frame members. The offsetting shown in this embodiment provides substantially spaced frame member engaging shoulders which is of advantage in that an effective bracing action results, also a more effective engagement of the parts than results where the offsets extend entirely or substantially across the struts.

In Fig. 5 the extreme edges 2| of 'the'parts M which are clamped around the frame members are folded or turned inwardly into abutting engagement with shoulders Hi.

In the embodiment shown in Figs. 6 and 7 the strut members l8 have offsets I9 of substantially greater depth and of general rectangular outline Patent is:

as compared to the offsets of the embodiment shown in the preceding figures.

In the embodiment of Figs. 8 and'9 the intermediate portion23 of the strut members 22 is longitudinally curved and tongue-like portions 24 are struckout therefrom to provide frame member engaging lugs. These parts 24 may be struck outbefore the strut members are applied or during the operation of applying thestrut members, I

In the embodiment shown in Figs. and 11 the strut members 25 have a, central intermediate portion 26 thereof offset to provide the shoula ders 21 which are in supporting engagement with the adjacent edges of the frame members. I

The border frame shown in Fig. 1A is asn sembled as a complete frame or unit to be applied to the spring assembly in completing or assembling the structure. It will be understood that theshape of the frame may be and is in commercial practice varied or changed according to the shape of finished cushion desired. ,This

frame is secured to the outer body springslby means of clip 28, some of which in the embodiment illustratedin Fig. lconnect certain of the springs to the outer member of theframe and' others to the inner member of the frame. The frame structure is very rigidand resistant to stresses which tend to distort the same in use; at the same time it is formed of comparatively light stock and is of comparatively light weight,

both of which are features greatly to be desired.

The structure isin effect a truss structure and is effective in resisting bending and wracking strains, the strut members being of substantial width and each strut member engaging each frame member at spaced points is very. effective to that end. i 4

I have not attempted to illustrate further adaptations andappiications ofth structure of the invention as it is believed the disclosure made will enablethose skilled in the art to embody or adapt the invention as'may be desired.
