Sand clock independent pocketed spring coil device and manufacturing method thereof

Abstract

The invention discloses a sand clock independent pocketed spring coil device and a manufacturing method thereof. The device comprises a spring coil body, wherein the spring coil body comprises a first connecting section, a first comfort section, a supporting section, a second comfort section and a second connecting section, the caliber of the first connecting section is identical with that of the second connecting section, the caliber of the first comfort section is identical with that of the second comfort section, the caliber of the first connecting section and the second connecting section is smaller than that of the first comfort section and the second comfort section, and the caliber of the first comfort section and the second comfort section is larger than that of the supporting section. The device has high elasticity, conforms to the body curve and can be effectively attached to every part of the body when people sleep in various postures, the requirements of people with different weights are met by means of different hardness grades of the five spring sections, the device can be perfectly attached to the body, and therefore sleeping quality is improved.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to an hourglass independent pocket spring device and a manufacturing method thereof. Background technique [0002] At present, in the upholstered home furnishing industry, most of the inner liners of mattress products are springs, and lock springs and traditional independent pocket springs are generally used. The elasticity of the lock spring is relatively poor, and the overall mattress is hard, making the user uncomfortable to sleep; the traditional independent pocket spring has a thick middle waist and relatively thin ends. During use, the spring is stressed from top to bottom, and the mattress The degree of subsidence is obvious. When the user weighs more than 80kg, the sleeping feeling is obviously soft, and long-term use is likely to cause spinal deformation. Neither the lock spring nor the traditional independent pocket spring can meet the needs of people of different weights...
