Darrell A. Richmond has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10206515
    Abstract: A pocketed spring assembly comprises parallel strings, each string joined to at least one adjacent string. At least some of the strings have pockets of different sizes before springs are inserted therein to accommodate for the fabric stretching due to some of the springs exerting greater force on the fabric than other springs. The ability to create pockets of different sizes enables springs of different strengths to be inserted into the pockets along a string, the string having a generally uniform height after assembly.

  • Publication number: 20180368584
    Abstract: A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. Each string is joined to at least one adjacent string. Each string has first and second opposed plies of fabric and a plurality of pockets formed along a length of the string by transverse seams joining the plies. At least one spring is positioned in each of the pockets. The double-layered fabric used to make at least some strings comprises two layers of non-woven spunbonded polypropylene fabric to reduce noise. The layers may be ultrasonically welded or point bonded together.

  • Publication number: 20180344045
    Abstract: A pocketed spring assembly comprises a plurality of parallel strings of springs held together with tabs. Longitudinal seams joining overlapping tabs extend generally the same direction as the strings of springs. Pockets are formed along a string of springs by aligned separating seams. At least one spring is positioned in each pocket. Each separating seam joins opposed plies of the string and keeps the spring in its pocket. Ends of aligned separating seams are spaced from each other, thereby improving airflow between pockets.

  • Publication number: 20180228297
    Abstract: A bedding or seating product comprises a pocketed spring assembly comprising a plurality of parallel strings of individually pocketed springs. The strings of springs may extend from head-to-foot or side-to-side of the product. Adjacent individually pocketed springs are separated from each other by at least one separating seam. Each of the separating seams comprises a branched end portion.

  • Publication number: 20180199727
    Abstract: A comfort layer for a bedding or seating product has slow-acting pockets characterized by the individual springs of the comfort layer being pocketed with either semi-impermeable or impermeable fabric. Each seam joining opposed plies of fabric around each of the coil springs of the comfort layer may be segmented, allowing air to flow between the segments, thereby increasing the luxury “feel” of the comfort layer. The method of making the comfort layer includes compressing the springs and creating pockets with a welding horn and an anvil.

  • Patent number: 10010189
    Abstract: A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs of different heights. Each string is joined to an adjacent string. Each string has first and second opposed plies of fabric and a plurality of pockets formed along a length of the string by transverse seams joining the plies. An upper end of each transverse seam is below the upper surface of the string so as to partially separate adjacent pockets within a string of springs when the spring is relaxed. The strings of springs have ventilation openings to increase airflow.

  • Patent number: 10010190
    Abstract: A pocketed spring assembly comprises a plurality of parallel strings of springs, each string joined to an adjacent string. Each string comprises a plurality of pockets formed along a length of the string by transverse seams joining first and second plies of fabric on opposed sides of springs. At least one spring is positioned in each pocket. Each spring has two end portions and a middle portion. The convolutions of the middle portion are greater in diameter and pitch than the convolutions of the end portions. Each interior transverse seam is cut or otherwise treated to create at least one divide enabling at least one end portion of the spring to compress without substantially compressing the middle portion of the spring.

  • Publication number: 20180049559
    Abstract: A pocketed spring assembly comprises a plurality of parallel strings of springs, each string joined to at least one adjacent string, each string comprising first and second opposed plies of fabric and a plurality of pockets formed along a length of the string by transverse seams joining the first and second plies. At least one spring is positioned in each pocket. Exterior strings have identical springs in their pockets. Interior strings have two different springs along their length, the outermost springs being firmer than the interior core springs. The pocketed spring assembly has increased firmness or edge support along all four sides due to the different coil springs of the assembly.

  • Patent number: 9764939
    Abstract: An apparatus for ventilating a web of material used in the manufacture of pocketed springs may be removably attached to a pocket coiler. The apparatus has an upper movable portion which pivots relative to a stationary portion. The stationary portion may be removably attached to the pocket coiler. Each portion has at least one roller, a web of material passing between the rollers during use. One of the rollers may have protrusions to create openings in the material before the material enters the pocket coiler.
