Patent number: 11109686Abstract: A pocketed spring assembly comprises parallel strings, each string joined to at least one adjacent string. At least some of the strings have springs of different gauge wire and some of the pockets of the strings having springs of different gauge wire are spliced together. At least some of the strings have springs of different geometries and some of the pockets of the strings having springs of different geometries are spliced together. At least some strings may have end sections with springs different than a middle section therebetween, the springs of the end sections being firmer than the springs of the middle section.Type: GrantFiled: May 21, 2019Date of Patent: September 7, 2021Assignee: L&P Property Management CompanyInventors: Guido Eigenmann, Darrell A.

Publication number: 20210045539Abstract: A posturized comfort layer for a bedding or seating product has different sections of different firmness due to different mini coil springs within the sections. The springs may be individually pocketed between two sheets of non-woven polypropylene fabric joined with circular seams or rectangular seams. Each circular seam joins opposed pieces of fabric around one of the mini coil springs with curved segments. Alternatively, rectangular seams join opposed pieces of fabric around each of the mini coil springs with linear segments. Regardless of the shape of the seams, the different firmness of the different sections of the comfort layer may be due to the mini-coil springs contained in the pockets.Type: ApplicationFiled: October 28, 2020Publication date: February 18, 2021Inventors: Guido Eigenmann, Darrell A. Richmond

Patent number: 10010190Abstract: 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.Type: GrantFiled: May 10, 2016Date of Patent: July 3, 2018Assignee: L&P Property Management CompanyInventors: Guido Eigenmann, Darrell A. Richmond, Thomas W. Wells

Pocketed spring assembly comprising strings of springs of different heights and enhanced ventilation
Patent number: 10010189Abstract: 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.Type: GrantFiled: April 4, 2016Date of Patent: July 3, 2018Assignee: L&P Property Management CompanyInventors: Guido Eigenmann, Darrell A.

Patent number: 9138801Abstract: Disclosed herein is a method of making a spring core (12) for a bedding or seating product (10). The spring core (12) has coil springs (26) having unknotted end turns (72, 74) made from high tensile strength wire. In each embodiment, the end turns (72, 74) of the coil springs (26) are generally U-shaped having one arcuate leg (76) longer than the other (78), the legs (76, 78) being joined by a connector (80) having an arcuate bump (81) therein. The springs (26) are oriented in the spring core (12) such that a long leg (76) of one end turn (72) abuts a short leg (78) of the adjacent end turn (72) prior to being wrapped in helical lacing wire (32). The high tensile wire enables the coil springs (26) to be manufactured using less wire than heretofore possible.Type: GrantFiled: September 3, 2014Date of Patent: September 22, 2015Assignee: L&P Property Management CompanyInventors: Guido Eigenmann, Niels S. Mossbeck, Darrell A. Richmond
