Application No. 09/557,509
One objective of Long's invention was to provide an improved continuous band
spring assembly which eliminates the presence of the helical lacing wires and/or any
other wire product for interconnecting the adjacent bands of coil springs. Still another
objective of Long's invention was to provide an improved continuous band spring
product which is quieter than prior art continuous band products because of the
absence of the helical springs and the absence of any potential for coil springs of one
band to rub against coil springs of adjacent bands and thereby give rise to noise.
Figures 1 and 2 illustrate a mattress 20. This mattress comprises a spring
interior 21 on the top and bottom surfaces of which there is a pad 19. An upholstered
covering 18 encases the spring interior 21 and the pads 19. The spring interior 21 is
formed from a plurality of longitudinally extending strips 22 of pocketed coil springs 31.
Each strip 22 of pocketed coil springs 31 comprises a fabric covering 24 within which
there is located a band of coil springs 23. These strips extend longitudinally of the
mattress 20 and are secured to top and bottom border wires 25 by conventional hog
rings 26. The border wires are located in the top and bottom planes of the mattress
and extend completely around the periphery of the spring interior 21.
Each band 23 of coil springs 31 is made from a single length of spring wire
shaped to form a plurality of individual coil springs 31 arranged in a row. Each band
