YOSl-I ITARO YA SU N O BY ATToRNLY 3,002,334 CORD CONSTRUCTION Y Y Yoshitaro Yasuno, Osaka, Japan, assignor to Tol'u Nishino, Mozu Umekita-lnachi, Sakai-shi, Osaka, Japan Filed June 3, 1959, Ser. No. 817,885 Claims priority, application Japan Aug. 30, 1958 3 Claims. (Cl. 57-149) This invention relates to a novel construction of mat or pad, of the type adapted for use as a oor covering, and for other purposes.
It is one object of the present invention to provide a novel and unique mat construction which is adapted to present the appearance of a conventional rope mat, but which is capable of being more economically and eiiciently produced than the conventional rope mat.
It is a further object of the present invention to provide a mat construction having the advantageous characteristics mentioned in the preceding paragraph which is extremely simple in structure, staunch and durable in use, and which is adapted to be easily manufactured out of relatively inexpensive materials, for economy in pro- -duction and sale at a reasonable price.
Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings, which form a material part of this disclosure.
The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.
In the drawings:
FIG. 1 is a longitudinal view showing a cord construction of the present invention, as in the process of manufacture;
FIG. 2 is a longitudinal view showing a pair of cords constructed in accordance with the present invention, and secured together according to the teachings of this invention for employment in a mat;
FIG. 3 is a sectional view taken substantially along the line 3 3 of FIG. l; and
FIG. 4 is a perspective view illustrating a mat formed of the cord constructions of FIGS. 1-3 according to the teachings of the present invention.
Referring now more particularly to the drawings, and speciiically to FIGS. 1 and 3 thereof, a cord construction is there generally designated and includes an inner core 11 formed of a plurality of longitudinally extending relatively heavy strands 12 arranged to have a generally circular cross sectional configuration, as seen in FIG. 3. ri`he strands 12 may be of any elongated, soft yieldable material, and are not exposed to view or subjected to appreciable wear, so that relatively inexpensive material may be employed. These strands 12 may extend substantally straight, longitudinally of each other, or may be Wound spirally or interwoven, if desired.
Extending along the exterior of the core 11 defined by the strands 12, are a plurality of relatively thin strands or threads 13. The threads 13 may be four in number, as illustrated, or more or less, as desired, and are preferably arranged at circumferentially spaced points about the exterior of the inner core 11. Also, the threads 13 may extend spirally about the inner core, if desired. The threads 13 are provided with an adhesive coating, one suitable adhesive coating for the threads 13 being that of rubberized mucilage. Thus, the threads 13 are in adhesive securement with the exterior of the inner core 11.
A plurality of outer yarns 14 are arranged in side by side relation with respect to each other, and in this relation helically coiled or Wound about the core 11 overlying the adhesive coated threads 13. The outer yarns States Patent O 3,002,334 ,Patented Oct. `3,, 1961 2 14 are wound in a tight helix or spiral about the core 11 to completely cover the latter. The spirally wound outer yarn 14 may be of various `colors and types to provide an ornamental and attractive, as `wellas wear resistant covering for the cord 10.
As the adhesive coated threads 13 are carried exten'orly on the core 11, and as the outer yarn 14 is wound tightly about the core, overlying the adhesive coated threads, it is apparent that the latter threads will serve to adhesively secure the outer yarn in its covering relation Wound about the core. While the outer yarn 14 is illustrated as composed of a plurality of threads or filaments, eight in number, it is appreciated that more or less threads or iilaments may be employed as desired.
In FIG. 2 is illustrated the cord 10 of FIGS. 1 and 3, and an additionally substantially identical cord 10a extending in adjacent longitudinal, side by side relation with respect to the cord 10. The cord 10a may be of substantially identical construction as the cord 10, but is arranged relative to the latter cord so that its outer yarns 14a extend spirally or helically in an angular direction opposite to that of the outer yarns 14 of the cord 10. Along their contiguous portions, the cords 10 and 10a are secured together by stitching 15, which may be of the zigzag or feather type. By this means the cords 10 and 10a are secured together throughout their lengths in the side by side relationship. The opposite angular direction of the spirally wound outer yarns 14 and 14a provides a symmetry of appearance, and also reinforces the cords against failure or coming apart, as the secured outer yarns would necessarily unwind in opposite directions.
A mat 16 is illustrated in FIGURE 4 as having been formed from the pair of cords 10 and 10a. It may there be observed that the secured cords 10 and 10a are ilexed and coiled in a plane coplanar with the plane of the cords themselves, so as to dene a relatively hat mat of a thickness equal to that of a single cord 10 or 10a. Of course, adjacent convolutions of the coiled cords 10 and 10a in the mat 16 are suitably secured together, as by stitching or other satisfactory means. Zigzag or feather stitching may be advantageously employed in securing together adjacent convolutions of the coiled cords in the mat.
From the foregoing, it is seen that the present invention provides a mat construction which fully accomplishes its intended objects, and is well adapted to meet practical conditions of manufacture and use.
Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be made within the spirit of the invention and scope of the appended claims.
What is claimed is:
1. A cord construction for a mat, said cord construction comprising a plurality of contiguous longitudinally extending inner strands dening a core, a plurality of threads extending longitudinally along the exterior of said core at circumferentially spaced locations thereabout, said threads being substantially completely coated with adhesive, and a plurality of outer yarns helically wound in covering relation about said core and overlying said threads, said outer yarns being secured to said core by said threads.
2. A cord construction according to claim 1, the adhesive coating on said thread comprising rubberized mucilage.
3. A cord construction according to claim l, said threads each being of substantially smaller cross-sectional size than said inner strands so as to lie along said core substantially within the cross-sectional-outline configuration of said core.
