Methods and systems for no-glue pocketed spring unit construction. Rows of pocketed springs, preferably arranged into modules of more than two pocketed springs surrounding a central hole, are ultrasonically welded together when paired vibrating probes and anvils press layers of pocketed spring fabric from the rows of pocketed springs together and a welding pulse is transmitted to the vibrating probe.

A reverse coil head coil and innerspring has a generally cylindrical and helical wire form coil body and opposing coil ends which terminate on opposite sides of a reference plane that passes through the coil body. The reverse coil head coils are interconnected in a matrix to form an innerspring wherein only one terminal end of each coil is located at a perimeter of the innerspring. Variations in the number and pitch of helical turns of the coil body are also disclosed.

A spring mattress is disclosed including a plurality of strings interconnected side by side, each string including a plurality of continuous casings and each casing including a coil spring. Further, in at least one embodiment, at least one of the casings in at least one of the strings includes a plurality of stretch openings into the interior of the casing, wherein at least some of said stretch openings are displaced in relation to each other in a lengthwise direction of the spring. At least one embodiment of the present invention also relates to a method and a device for manufacturing of such a mattress, as well as to a bed adapted for such a mattress.

Provided is a mattress wherein the elastic characteristics of each portion can be changed simply and inexpensively depending on the user's preference. A mattress (10) has a plurality of spring units (60, 70, 80, 90) respectively constituted by holding a plurality of vertically stretchable pocket coils integrally, a lower elastic body (40) in which a housing space (44) capable of housing and holding the spring units (60, 70, 80, 90) is formed, and an upper enclosure (21) and a lower enclosure (30) for covering the outer periphery of the lower elastic body (40), wherein the lower elastic body (40) is provided with a partitioning elastic body (50) for dividing the housing space (44) into a plurality of spaces, and the spring units (60, 70, 80, 90) are formed in such a shape that each of the spring units can be housed in the divided housing spaces (44), and are housed and held in the respective divided housing spaces (44).

A mattress spring structure (10) is provided with a strengthened central area (C) thereon to provide greater support for a user's body lumbar region when received thereon. The support is provided with a strengthening structure (30) having a continuous frame member (54) and a strengthening pattern (53). The continuous frame (54) encircles coil springs (12) over a major expanse of the mattress's central area (C); this frame is connected to mattress coils along the frames longitudinal (34, 36) and traverse (38, 40) segments. The strengthening pattern (53) has two metal bars (51, 52) arranged inside and connected to the continuous frame member (54). The strengthening pattern (53) may be connected to the spring coils (12) and contain additional metal straps (56, 59). The strengthening structure (30) is positioned and arranged to causes substantially uniform depression of adjacent coil springs to the continuous frame member (54) in the lumbar zone thereby eliminating any undesired upward pressure into the user's back.

A system and method for manufacturing pocketed compound nested coil springs includes inserting a compressed, preferably pocketed, smaller coil spring into a horizontally oriented larger coil spring either prior to compressing and inserting the outer coil spring into pocket material or after the larger coil spring has been pocketed thereby requiring the first spring to be inserted into and through an opening in the pocket material.
摘要:
A unitary mattress assembly comprises a plurality of coil springs interarranged to define a single innerspring core having a generally rectangular shape in plan. The core has a first portion which is sized to accommodate a first sleeping person and comprises coil springs having a first preselected compressive strength. Adjacent to the first portion is a second core portion sized to accommodate another sleeping person and having coil springs of a different compressive strength than the springs of the first portion. By the foregoing construction, a mattress may be manufactured having a single innerspring core but having two regions of differing firmness to suit the particular preferences of two people.
摘要:
A spring core for a mattress consisting of a plurality of side-by-side rows of identically configured helical coil springs each made of a single piece of wire having a central portion of a first radius defining a central spring axis and terminating at opposing ends with unknotted upper and lower end turns disposed in planes substantially perpendicular to the spring axis. The springs are connected with each other at their upper and lower turns by connecting lacing wires. The upper and lower turns are each substantially U-shaped, having a longer relatively straight leg and a shorter arcuate leg located at the free end of each end turn, the legs connected to each other by a base web. The radius of the shorter arcuate leg is substantially less than the first radius of the central portion of each coil spring. All the coil springs are oriented in the same direction, except along an edge region of the spring core.

A mattress spring clip to secure the wire of a border wire assembly to coils of adjacent coil springs in an innerspring assembly for a mattress, wherein the clip comprises a unitary length of spring bias material, such as metal having a relatively broad width, and curved to form a pair of reverse loops, each having entrances which are narrower than their respective loop pockets whereby the entrances have to spread apart for the wire of a border wire assembly to pass into one of the loop pockets and for the coil of an adjacent coil spring to pass into the other loop pocket. The entrances then snap back to their original spring biased positions to hold the wire and coil in their respective pockets.
摘要:
A modular innerspring and box spring assembly which can be put together by the end use customer from innerspring and box spring modules. An innerspring module consists of a plurality of coil springs joined together by helical wire fasteners in a generally rectangular configuration having dimensions which when assembled with other like modules in side-by-side and end-to-end relationship make up a completed modular innerspring assembly of the size and shape needed to make a twin, twin extra long, full, full extra long, queen and king size mattress. A top boundary wire assembly extends around the top peripheral edge of the completed modular innerspring assembly and a bottom boundary wire assembly extends around the bottom peripheral edge, in each case secured to adjacent coil springs by a double hook clip. A box spring module consists of a frame made up of end and side strips plus intermediate slats having a plurality of springs secured thereto and extending upwardly therefrom in a generally rectangular configuration having dimensions which when connected with other like box spring modules in side-by-side and end-to-end relationship make up a completed modular box spring assembly of whatever size and shape needed to support a twin, twin extra long, full, full extra long, queen and king size mattress. The box spring modules are secured together by L-shaped angle irons on each bolted to those of adjacent modules.
