laser 4 wk United States Patent Ofillce 2,855,027 Patented Oct. 7, 1958 UPHOLSTERY EDGINGS Albert M. Bank, Jersey City, N. J. Application March 14, 1957, Serial No. 645,933 11 Claims. (Cl. 155-184) The present invention relates to upholstery edgings or welts which are mounted along the front edge of seat structures and in present-day upholstery construction, they are usually secured along the border wire of spring assemblies. Besides their protective function, these welts support the forward ends of the seat cushions, make a proper bend or break in the underside of the cushion to hold it properly positioned on the seat against forward shift and to maintain the cushion downwardly rearwardly sloped at seat edge. These welts are of resilient quality, more or less, and after some time of being subjected even in normal use to the distorting forces offered by persons sitting, that they get deformed and disrupt the orderly look of the furniture because of the haphazard positions assumed by the cushions at front edge when the seat is not in use and of course, such distortion, ham.- pers their intended function.

It is therefore the principal object of invention to provide a novel and improved welt construction which will avoid the occurrence of the mentioned objectionable conditions. To attain this important object, I provide a welt in which the cushion-supporting region thereof is never subjected directly to force of the weight of persons seated, and upon the seat being cleared, such region, though having shifted, will automatically assume its initial position to properly raise and support the front edge of the seat cushion.

A further object of this invention is to provide a welt of the character described and having the attributes set forth, which is of novel and improved construction, reasonably cheap to manufacture, easy to mount and efficient in carrying out the various functions for which it is designed.

Other objects and advantages will become apparent as this disclosure proceeds.

In the practice of this invention, one form this welt may assume, comprises a first core section provided with attachment fins, one rearwardly horizontal and the other extending downwardly from said first core section, forwardly of the first attachment fin. The first core sec tion carries a second core section along the top thereof. Said second core section and the attachment fins are all coextensive lengthwise with the first core section. The juncture of the core sections is of course lengthwise of the welt structure and has resilient quality and serves axis-like for the swing movement of the second core section. Such juncture is comparatively thin. The trans verse cross-section of the second core section may be substantially round. The cross section of the first core 7 section may also be round. Other shaped cross sections may be chosen, but it is essential that the juncture of the core sections shall be comparatively thin and have some resilient quality.

It is preferred that the line of juncture of the two core sections shall be along the forward surface of the first core section and it is mandatory that upon application of a downward force on the second core section, that said second section shall be swung downwardly forwardly of the first core section. It is best that the core sections shall be at least near tangency longitudinally. It is also preferred that the plane passing through the center lines of both core sections shall make an angle of between 45 to 60 degrees with the horizontal plane tangent to the underside of the first core section. I may also note, that if desired, the entire welt may be an extrusion of rubberized or rubber-like material, or as heretofore, there may be a fabric or paper covering for the cores out of which covering, the attachment fins are formed.

A more detailed description will now be given.

In the accompanying drawings forming part of this specification, similar characters of reference indicate correspondent parts in all the views.

Fig. 1 is a fragmentary perspective View showing a welt embodying the teachings of this invention.

Fig. 2 is a diagrammatic end view of the welt shown in Fig. 1, indicating the condition and position of the components thereof when subjected to the weight of a person seated and its normal condition when the seat is clear.

Fig. 3 is a fragmentary top plane view of a spring assembly along whose border wire, the welt is shown mounted.

Fig. 4 is similar to Fig. l, but shows the welt as an extrusion; all components being integral.

Fig. 5 is a section of modified core structure.

In the drawings are shown forms of edgings this invention may assume. The numeral 15 designates one of them generally. It consists of a first welt body 16 pro- Vided with the lengthwise attaching fins 17 and 18, which are preferably tangent thereto, one downwardly in front and the other rearwardly from its undersurface. Atop the first welt body and lengthwise thereof, is a second welt body 19 preferably of smaller thickness and overhanging it forwardly. The cross sections of the welt bodies may be circular but of importance is that they form a channel 20 along the front of the edging 15 to permit forwardly downwardly pivotal movement of the upper welt body 19. Their construction may comprise cores 16, 19' of crumpled or twisted paper or of other materials well known in this art. Such cores are encompassed by a fitted covering 21 which may be of burlap or other suitable sheeting. As is well known, the attaching fins 17, 18 may be formed of the covering as shown in Fig. l for example. The front and rear parts of the covering are preferably joined between the cores as by the lines of stitching indicated at 22. It is also practical to make this edging in one piece as an extrusion of rubber-like material as shown in the embodiment illustrated in Fig. 4. Here as in Fig. 1, the junction 23 is comparatively of thin section. Regardless of material used, the edging of course, shall have resilient quality; especially said junction 23.

The edging 15, or 15 may be mounted along the border wire of a spring assembly in upholstery. It is laid on so that the fin 17 is in front of and abuts the border wire 28 while the rearward fin 18 is on top of the springs 24. The fins may be attached by hog rings 25, 26 to said border wire and the top turns of the springs 24 respectively or in other suitable manner.

When the edging is subjected to the weight of a person seated on a chair or sofa whose seats front edge is provided with this edging the welt body 19 will be swung downwardly to position 19a as shown in Fig. 2, thereby flexing the juncture of the welt bodies 16, 19 and will cause some distortion in the cross-sectional form of said welt bodies as indicated in dotted line in said Fig. 2. It is to be noted that a considerable part of the stress is spent at such junction and there occurs less of deformation of the corpus of the edging to assume its shape in use when the seat is occupied. It is evident that when the seat is clear, the edging 15 or 15 will automatically assume its original condition to raise the front region of the seat pillows of the upholstered article.

The cores 16, 19, may be of felt material or other suitable substances known in the art, though twisted paper is popular in present day manufacture. Also, said core may be a hollow resilient tube of plastic or rubber-like material 30 or such tube may be filled with twisted paper 31, or felt and the like.

This invention is capable of numerous forms, for instance the edging sections may be other than of round cross section as shown, and applicable for other uses without departing from the essential features herein disclosed. It is therefore intended and desired that the embodiments shown shall be deemed illustrative and not restrictive and that the patent shall cover all patentable novelty herein set forth; reference being had to the following claims rather than to the specific description herein to indicate the scope of this invention.
