Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention and should not be construed as limiting the present invention.

As shown in fig. 1-4, a spring according to an embodiment of the present invention is formed by winding at least one wire.

According to the spring core 100 of the embodiment of the utility model, the spring is formed by winding at least one strand of metal wire, and the elasticity of each spring can be adjusted by adjusting the type, the number and the thickness of the metal wire so as to meet the requirements of users.

It can be understood that when the spring is formed by winding a plurality of metal wires with different types, quantities and thicknesses, the stiffness coefficient of the spring can be adjusted by adjusting the types, the quantities and the thicknesses of the metal wires, the stiffness coefficient of the spring can be adjusted according to requirements, and the use comfort and the service life of the spring can be further adjusted. Specifically, in the area where the spring bed core is subjected to a large force, the spring is made using a relatively high stiffness (relative to the area where the force is small) wire, or using a relatively large number of wires (relative to the area where the force is small). When the spring is deformed due to extrusion force, the metal wires rub against each other to absorb partial energy, so that the service life of the spring is prolonged, and the service life of the whole spring bed core is prolonged.

Therefore, the spring provided by the embodiment of the utility model has the advantages of comfort in use, long service life and the like.

For convenience of understanding and description, in the present embodiment, a spring wound by a plurality of strands of wire is referred to as a first spring 111, a pocketed spring loaded with the first spring 111 is referred to as a first pocketed spring 11, a string of pocketed springs composed of the first pocketed spring 11 is referred to as a first string of pocketed springs 1, a spring wound by a single strand of wire is referred to as a second spring 211, a pocketed spring loaded with the second spring 211 is referred to as a second pocketed spring 21, and a string of pocketed springs composed of the second pocketed spring 21 is referred to as a second string of pocketed springs 2.

As shown in fig. 3 and 4, according to the spring core 100 of the embodiment of the utility model, the metal wire is in the shape of a spiral cylinder, and during the use process, when the spring is stressed and deformed, the friction between the metal wires can be reduced through the spiral cylinder metal wire, so that the service life of the first spring 111 is prolonged.

When the diameter of the cross section of the metal wire is smaller than 0.3mm, when the first spring 111 is stressed to deform, elastic strain and breakage easily occur to elastic elasticity, and when the diameter of the cross section of the metal wire is larger than 3.2mm, the rigidity of the metal wire is increased, the adjustable range of the elasticity and the rigidity of the first spring 111 is reduced, and the manufacturing cost is increased. Preferably, the diameter of the cross section of the wire is 2.5 mm. It should be noted that, when the first spring 111 is wound by using multiple strands of metal wires, each strand of metal wire may also be made of other elastic materials, and different elastic materials with different diameters may be used to form the first spring according to the need, for example, the first spring is wound by using plastic with a cross section diameter of 0.5mm, spring steel with a cross section diameter of 1mm, and rubber with a cross section diameter of 1.2 mm.

In some embodiments, the wire is generally rectangular in cross-section, with the wire cross-section having sides between 0.3mm and 3.2 mm.

In some embodiments, the spring is formed from 3-8 strands of wire.

According to the spring core 100 of the embodiment of the utility model, when the wire wound around the first spring 111 is less than 2 strands, in order to satisfy the elasticity and strength of the first spring 111, the thickness of the wire needs to be adaptively increased (for example, when the wire is a spiral cylinder, the diameter of the wire is increased), which results in that the adjustment amount of the first spring 111 is reduced (only 2 strands of wire can be adjusted), the application range is small, when the wire wound around the first spring is greater than 8 strands, the required cost is correspondingly increased, and on the premise that the required elasticity is the same, more wires are used to manufacture the first spring 111, the thickness of each strand of wire is smaller, and when the first spring 111 is deformed by being pressed by force, the wires are prone to generate elastic strain and even break. When the metal wire is 3-8 strands, the first spring 111 has the advantages of wide elastic adjustment range and long service life.

Specifically, the spring is formed by winding a carbon steel wire with a cross section being generally circular and the diameter of the cross section being 1.2mm, a silicon-manganese steel wire with a cross section being generally circular and the diameter of the cross section being 1.4mm and a stainless steel wire with a cross section being generally circular and the diameter of the cross section being 1.0 mm.

According to the string of pocketed springs according to an embodiment of the second aspect of the utility model, the pocketed springs comprise a plurality of pocketed springs, each pocketed spring comprising a spring of the embodiment, respectively.

The spring core 100 according to the embodiment of the third aspect of the present invention includes a plurality of the string of pocketed springs according to the embodiment, the plurality of strings of pocketed springs being arranged in a transverse direction (left-right direction as viewed in fig. 1), each string of pocketed springs extending in a longitudinal direction (front-back direction as viewed in fig. 1) and in the same string of pocketed springs, elasticity of each spring varying in the longitudinal direction.

For convenience of description, the spring may be the first spring 111 or the second spring 211, unless otherwise stated.

According to the spring core 100 of the embodiment of the utility model, the elasticity of each spring in the same bagged spring string is adjusted, so that the elasticity of the spring can be adapted to different stress areas on the spring core 100. Specifically, as shown in fig. 1 and 2, when the string of pocketed springs is used to make the spring core 100, the front and rear ends of the spring core 100 are common parts, and thus the elasticity of the springs located at the front and rear ends of the pocketed springs is large, while the springs opposite to the head (adjacent to the rear end of the string of pocketed springs) and the foot (adjacent to the front end of the string of pocketed springs) are less stressed during use than the springs opposite to the trunk, and thus the elasticity of the springs opposite to the head and the foot is less relative to the elasticity of the springs opposite to the trunk. It can be appreciated that by adjusting the elasticity of the springs in the same string of pocketed springs, the elasticity of the springs in the same string of pocketed springs can be matched with the stressed area, and thus the overall service life of the spring core 100 can be enhanced.

Meanwhile, the spring can be attached to the curve of the user by adjusting the elasticity of the spring, and a comfortable sleeping environment is provided.

Therefore, the spring core body provided by the embodiment of the utility model has the advantages of comfort in use, long service life and the like.

In some embodiments, the elasticity of the spring varies in a wave-like manner in the longitudinal direction.

It will be appreciated that the variation in the elasticity of the spring in the longitudinal direction may be such that the spring more closely follows the curvature of the body in the longitudinal direction, for example by using a more elastic (with respect to the head and feet) spring at the waist location of the body.

In some embodiments, the plurality of strings of pocketed springs includes a first string of pocketed springs 1 and a second string of pocketed springs 2, the springs in the first string of pocketed springs 1 being wound from a plurality of strands of wire, the springs in the second string of pocketed springs 2 being wound from a single strand of wire, the first string of pocketed springs 1 and the second string of pocketed springs 2 being laterally juxtaposed.

According to the spring core 100 provided by the embodiment of the utility model, the first bagged spring string 1 and the second bagged spring string 2 are matched, so that the cost can be further saved. Specifically, a first string of pocketed springs 1 is used in areas where the spring bed core is under high stress, and a second string of pocketed springs 2 is used in areas where the spring bed core is under low stress. For example, the first pocket spring string 1 is positioned in the middle of the spring bed core, and the second pocket spring string 2 is arranged on the left side and the right side of the first pocket spring string 1 in parallel. Therefore, in the using process, the first bagged spring string 1 is located in the area with large stress, and the second bagged spring string 2 is located in the area with small stress, so that the service life of the spring bed core is prolonged. Wherein the elasticity of the second springs 211 in the second spring string 211 in the longitudinal direction is substantially the same as the elasticity of the first springs 111 in the first spring string.

Preferably, according to the spring core 100 of the embodiment of the present invention, the number of the first string of pocketed springs 1 can be further reduced and the cost can be saved by alternately arranging the first string of pocketed springs 1 and the second string of pocketed springs 2 in the left-right direction. Specifically, in the use process of the spring bed core, the first bagged spring string 1 and the second bagged spring string 2 can share the pressure applied to each other, so that the first bagged spring string 1 is restrained and supported by the two second bagged spring strings 2 in the left-right direction, and similarly, the second bagged spring string 2 is restrained and supported by the two first bagged spring strings 1 in the left-right direction, and further the use of the first spring 111 is further reduced on the premise of ensuring the whole service life of the spring bed core, and the cost is saved.
