摘要:
Innerspring coils for innersprings for mattresses and other reflexive support structures, have generally helical coil bodies and at least one non-helical segment or step which extends between one or both axial ends of the coil body and one or both of the coil ends. The step or steps may be linear or non-linear, and parallel to or angularly disposed with respect to a longitudinal axis of the coil body. When located proximate to a coil end, the step extends out of the plane in which the coil end lies. One or more steps may alternatively be formed intermediate to helical turns of the helical coil body.

A spring bed has a permanently fitted covering (16) and furthermore has an additional covering (17) that is form-sewn and folded in under the bed and fastened with the Velcro strip (20, 21) against the bottom of the bed.

A coil spring for a bed mattress, At least one of contact wiring portions 16-5 and 16-5' of the upper and lower exposed wiring portions 16 and 16' which abut to the end wiring portions 14 while the upper and lower exposed wiring portion 16, 16' are being compressed has a contact surface A which is in contact with one corresponding end wiring portion of the end wiring portions 14, whereby frictional noise between the exposed wiring portion 16, 16' and the end wiring portion 14 is prevented. It is possible to consequently remove friction that is created due to contact between the exposed wiring portion and the end wiring portion while the exposed portion is being compressed, thereby preventing noise. The exposed wiring portion and the body wiring portion move only upward and downward without being displaced or deformed in the lateral direction, thereby increasing longevity.
摘要:
A mattress comprising asymmetrical coil springs with nonlinear spring rates provides comfort to users with different weights. The lower portion of the spring is cylindrical and the upper portion is conical or frustoconical. This arrangement causes the spring to undergo linear compression before undergoing nonlinear compression. The result is a mattress that is sufficiently soft for lighter users and sufficiently firm for heavier users.

Die Erfindung betrifft eine Federstrebe, welche vorteilhaft z.B. beim Bau von Betten und Postermöbeln verwendet werden kann. Die Erfindung betrifft weiterhin einen Matratzenträger, eine Matratze und ein Polsterelement, welche derartige Federstreben aufweisen. Erfindungsgemäß weist die Federstrebe (10,11; 20,21; 30,31; 40,41; 50; 60,61; 70,71; 80; 90,91) eine Stützstrebe (101; 201; 301; 401) und zumindest ein Spiralfederelement (104; 204; 304; 404; 504; 304.1, 304.2; 404.1, 404.2; 504.1, 504.2) auf. Dieses ist längs mit der Stützstrebe derart verbunden ist, dass die Längsachse (1) des mindestens einen Spiralfederelements und die Längsachse (A2) der Stützstrebe zumindest bereichsweise parallel sind. Eine Federstrebe gemäß der Erfindung stellt ein besonders zum Aufbau z.B. von Matratzenträgern und Polstermöbeln geeignetes Grundbauteil dar. Die erfindungsgemäße Verbindung der Stützstrebe mit dem Spiralfederelement in Längsrichtung, also parallel zur zentralen Achse des Spiralfederelements, bietet den Vorteil, dass bei der erfindungsgemäßen Federstrebe die Funktionen von Halterung und Federung weitgehend voneinander entkoppelt sind.
