Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the present utility model, the terms "disposed," "connected" and "connected" are to be construed broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; may be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements, or components. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

Furthermore, the terms "first," "second," and the like, are used primarily to distinguish between different devices, elements, or components (the particular species and configurations may be the same or different), and are not used to indicate or imply the relative importance and number of devices, elements, or components indicated. Unless otherwise indicated, the meaning of "a plurality" is two or more.

The current spring comprises a plurality of circular coils, and after the spring bagging, the spring can easily rotate in the bag during transportation, rolling movement or production and forming, and if coils on two adjacent springs just reach the same level in the rotation process, the two springs are easy to collide, so that abnormal sound is generated in the compression process, and the spring can deform after long-time use.

Based on the above analysis, the embodiment of the application provides a pocketed spring assembly, a bed net and a mattress, wherein the pocketed spring assembly is attached to a polygonal cavity wall of a pocket body through at least one polygonal coil on a coil spring, so that the coil spring is fixedly attached to a containing cavity, and the coil spring is fixed in the pocket body in the rotating direction, so that the coil spring cannot rotate in the pocket body.

The technical scheme of the present utility model will be described below with reference to examples and drawings.

In a first aspect, referring to fig. 1 and 2, an embodiment of the present application provides a pocketed spring assembly 100 comprising a coil spring 110 and a pocket 120. The coil spring 110 includes a first coil portion 111 and a second coil portion 112 formed on at least one end of the first coil portion 111. The first coil portion 111 has a polygonal coil 1111. The second coil portion 112 has a circular coil 1121 and/or an elliptical coil.

In more detail, the coil spring 110 may be formed by helically winding a spring wire, typically steel wire, along a vertical axis. The polygonal coil 1111, the circular coil 1121, or the elliptical coil is obtained by winding the spring wire into a specific shape. As can be seen, the polygonal coil 1111 is a coil wound in a polygonal shape, and both ends of the coil are connected to the end of one coil and the start of the next coil, respectively. Similarly, the circular coil 1121 refers to a coil wound in a circular shape, and the elliptical coil refers to a coil wound in an elliptical shape. It is understood that the coil spring 110 may be formed by connecting a plurality of spring wires.

The pocket 120 defines a housing cavity 121 therein, and the first coil portion 111 is housed in the housing cavity 121. Optionally, the second coil portion 112 is also accommodated in the accommodating cavity 121. The housing chamber 121 has a polygonal chamber wall 1211, and at least one polygonal coil 1111 is attached to the polygonal chamber wall 1211. Preferably, the bag 120 is a cloth bag or a polymer bag. The pocket 120 is formed with a pocket 122 for accommodating the coil spring 110, and the pocket 122 is preferably provided at a side of the pocket 120, and the pocket 122 can be sealed by ultrasonic welding, gluing, zipper, etc. after accommodating the coil spring 110, to seal the accommodating chamber 121; for example, a non-woven sheet (not shown) having a shape complementary to the shape of the pocket 122 is ultrasonically welded at the pocket 122 shown in fig. 1, so that the non-woven sheet is combined with a portion of the pocket 120 shown in fig. 1 to form a complete pocket 120. However, the pocket 120 that encloses the coil spring 110 may also be formed directly on the coil spring 110.

It will be appreciated that the number of sides of the polygonal coil 1111 is equal to that of the polygonal chamber wall 1211 and the size and shape are matched so that the polygonal coil 1111 is closely attached to the polygonal chamber wall 1211 after the coil spring 110 is mounted in the pocket 120, and the coil spring 110 is fixed in the pocket 120 in the rotation direction.

Illustratively, when the pocketed spring assembly 100 is used as a part of a furniture product, the pocketed spring assembly 100 is fixed in the furniture product, and further the coil spring 110 is fixed without rotation, so as to avoid the problem of collision caused by rotation of the coil spring 110, and further avoid the problem of abnormal sound and deformation caused by spring collision. The pocketed spring assembly 100 is not limited to use in mattresses, but may be used in furniture products having spring elements such as sofas, single chairs, seat cushions, and the like.

Further, although the quadrangular coil and the pentagonal coil can be fixed in the rotational direction by bonding the polygonal cavity wall 1211 having a shape matching the shape thereof, the corners of the quadrangular coil are right angles, which easily causes the bag 120 to be scratched during bagging. When two coil springs 110 having quadrangular or pentagonal coils are arranged side by side, the quadrangular or pentagonal coils on the two coil springs 110 are liable to be in collision with each other in coil corners. While the polygonal coil 1111, such as an octagonal coil, is relatively close to a circular shape, it cannot be well fixed in the pouch 120 by being attached to the polygonal chamber wall 1211. Therefore, preferably, the polygonal coil 1111 is a hexagonal coil, and the polygonal chamber wall 1211 is a hexagonal chamber wall. The hexagonal coil is easy to pack, is not easy to rotate in the bag, has high stability and can not generate collision problem.

If the number of the polygonal coils 1111 is too small, sufficient support may not be formed. If the number of the polygonal coils 1111 is too large, the height of the coil spring 110 may be too high, and the product in which the coil spring 110 is disposed may be too high, for example, the height of the current mattress is required to be 22cm to 28cm, and if the number of the polygonal coils 1111 is too large, the height of the coil spring 110 may be too high to be used for manufacturing the mattress meeting the height requirement. Therefore, referring to fig. 2, it is preferable that the first coil part 111 has 4 to 8 polygonal coils 1111; for example 4, 6 or 8.

It will be appreciated that if the coil spring 110 is formed of only the first coil portion 111, the opening of the polygonal coil 1111 at the end of the first coil portion 111 is too large, such as the polygonal coil 1111 may cause a dent problem when the mattress is used, resulting in poor supporting effect of the pocketed spring assembly 100. By the arrangement of the second coil portion 112, the second coil portion 112 is used for shrinking the end opening of the coil spring 110, so as to avoid the problem of dishing, and facilitate the supporting effect of the pocketed spring assembly 100.

Further, referring to fig. 1 and 2, there are two second coil parts 112, and two second coil parts 112 are formed at both ends of the first coil part 111, respectively, to secure the supporting effect of both ends of the pocketed spring assembly 100.

Further, referring to fig. 2, the outer diameter of the coil spring 110 becomes smaller from the middle to both ends in the height direction of the coil spring 110. The height direction is the illustrated Z0-Z1 direction. As described above, the excessively large opening of the spring coil causes a problem of dishing, and thus, the middle outer diameter of the coil spring 110 is large, and elasticity is better. The outer diameters of the two ends are small, so that the excessive opening areas of the two ends are avoided, and the problem of dishing is further avoided, and the bearing effect of the pocketed spring assembly 100 is improved.

If the number of the circular coils 1121 of the second coil portion 112 is too small, a sufficient supporting feeling cannot be provided. On the contrary, if the number of the circular coils 1121 of the second coil portion 112 is too large, the total number of the coils of the coil spring 110 is within a certain range, so that the number of the polygonal coils 1111 is reduced, and the coil spring 110 is still easy to rotate after bagging. Preferably, the second coil part 112 has 2 to 3 turns of the circular coil 1121.

In a second aspect, referring to fig. 3, an embodiment of the present application provides a bed net 200 comprising a plurality of pocketed spring assemblies 100 according to the first aspect.

If the polygonal coils 1111 of the adjacent two coil springs 110 are located at the same height, a collision problem occurs, and thus, it is preferable that the plurality of coil springs 110 are linearly arrayed, and the polygonal coils 1111 of the adjacent two coil springs 110 are staggered in the height direction. The height direction is the illustrated Z0-Z1 direction.

In a third aspect, embodiments of the present application provide a mattress having a bed net 200 according to the second aspect.

The above describes in detail a pocketed spring assembly, a bed net and a mattress according to embodiments of the present utility model, and specific examples are applied herein to illustrate the principles and embodiments of the present utility model, and the above description of the embodiments is only for helping to understand the principles and the mattress of the present utility model: meanwhile, as those skilled in the art will vary in the specific embodiments and application scope according to the idea of the present utility model, the present disclosure should not be construed as limiting the present utility model in summary.
