[0027] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0028] The following refers to the attached Figures 1 to 5 to describe the knotted spring, spring string and mattress of the embodiment of the present utility model.
[0029] As Figure 1 and Figure 2As shown in the figure, the knotting spring 1 of the embodiment of the present utility model is formed by helically winding a spring wire. The spring wire includes a first spring coil 11, a second spring coil 12, and a helical section 13. The first spring coil 11 and the second spring coil 12 are respectively connected to both ends of the helical section 13. The first spring coil 11 has a first knotting portion 111, and the second spring coil 12 has a second knotting portion 121. In the projection plane orthogonal to the axial direction of the knotting spring 1, the first knotting portion 111 and the second knotting portion 121 are arranged at intervals along the circumferential direction of the knotting spring 1.
[0030] For the knotting spring 1 according to the embodiment of the present utility model, since the first knotting portion 111 and the second knotting portion 121 are arranged at intervals along the circumferential direction of the knotting spring 1, when the knotting spring 1 is subjected to an axial compressive force, the first spring coil 11 and the second spring coil 12 can be more evenly stressed. Compared with the scheme of arranging the first knotting portion 111 and the second knotting portion 121 on the same side of the knotting spring 1, the phenomenon of the knotting spring 1 tilting when stressed can be avoided, the stability of the knotting spring 1 when stressed can be better, which is beneficial to improving the support effect of the mattress and enhancing the user experience.
[0031] It can be understood that the knotting spring 1 is formed by helically winding a single spring wire. In order to fix the ends of the spring wire, the ends of the spring wire need to be knotted. Specifically, the first spring coil 11 is closed at the position of the first knotting portion 111, and the second spring coil 12 is closed at the position of the second knotting portion 121. One end of the helical section 13 is led out from the position of the first knotting portion 111 of the first spring coil 11, and the other end of the helical section 13 is led out from the second knotting portion 121 of the second spring coil 12.
[0032] The inventor of the present application found through experimental research that for the scheme of arranging the first knotting portion 111 and the second knotting portion 121 of the knotting spring 1 on the same side of the knotting spring 1, since the first knotting portion 111 and the second knotting portion 121 are opposite (coincident) in the up and down direction of the knotting spring 1, when the knotting spring 1 is subjected to a downward pressure, the stiffness difference between the side of the knotting spring 1 adjacent to the knotting portion and the side of the knotting spring 1 far from the knotting portion is relatively large, resulting in inconsistent compression amounts on both sides of the knotting spring 1, and causing unstable problems such as the knotting spring 1 being prone to tilting when compressed, which affects the support effect of the knotting spring 1.
[0033] However, for the knotting spring 1 of the embodiment of the present utility model, the first knotting portion 111 and the second knotting portion 121 are arranged at intervals along the circumferential direction of the knotting spring 1. In other words, the first knotting portion 111 and the second knotting portion 121 are staggered along the circumferential direction of the knotting spring 1, which can improve the stability of the knotting spring 1 when stressed, so that its support effect is better.
[0034] Optionally, in a projection plane orthogonal to the axial direction of the knotted spring 1, the first knotted portion 111 and the second knotted portion 121 are symmetrically arranged along the radial direction of the knotted spring 1. It can be understood that the first knotted portion 111 and the second knotted portion 121 are arranged on both sides of the knotted spring 1 in the radial direction. When the knotted spring 1 is subjected to a downward pressure, due to the symmetrical arrangement of the first knotted portion 111 and the second knotted portion 121, the stiffness difference between the two sides of the knotted spring 1 can be made smaller, so as to ensure that the compression amounts at various positions of the knotted spring 1 when compressed are substantially equal, thereby improving the stability of the support of the knotted spring 1.
[0035] In one example, the number of winding turns of the spring wire is 3.5 turns (three and a half turns), 4.5 turns (four and a half turns) or 5.5 turns (five and a half turns). It can be understood that when the knotted spring 1 is wound, it is not arranged in a whole circle, so that the first knotted portion 111 and the second knotted portion 121 can be exactly arranged on both sides of the knotted spring 1 in the radial direction, so as to improve the stability of the support of the knotted spring 1.
[0036] Optionally, the winding outer diameters of the first spring coil 11 and the second spring coil 12 are both larger than the winding outer diameter of the helical section 13. It can be understood that the outer diameters of the spring coils at both ends of the knotted spring 1 are larger, so as to increase the support area at the ends of the knotted spring 1, and can make the overall structure of the knotted spring 1 more stable and not easy to tip over.
[0037] Furthermore, the winding outer diameters of the first spring coil 11 and the second spring coil 12 are equal. In other words, the first spring coil 11 and the second spring coil 12 are of the same size, so that it is not necessary to distinguish between the upper end and the lower end of the tension spring, thereby simplifying the subsequent assembly process of the knotted spring 1.
[0038] As Figure 1 and Figure 3 shown, a spring string according to another embodiment of the present invention includes a knotted spring 1 and a string spring wire 2. The knotted spring 1 is the knotted spring 1 of the present invention. There are multiple knotted springs 1 and they are arranged in sequence along the first direction (such as Figure 3 the A direction in
[0039] According to the spring string of the embodiment of the present utility model, since the first knotting part 111 and the second knotting part 121 are arranged at intervals along the circumferential direction of the knotted spring 1, when the knotted spring 1 is subjected to an axial compressive force, the first spring coil 11 and the second spring coil 12 can be more evenly stressed. Compared with the solution of arranging the first knotting part 111 and the second knotting part 121 on the same side of the knotted spring 1, the phenomenon of the knotted spring 1 tilting when stressed can be avoided, the stability of the knotted spring 1 when stressed can be better, which is beneficial to improving the support effect of the mattress and enhancing the user experience. In addition, since the string spring wire 2 extends along the first direction and is sequentially connected to a plurality of knotted springs 1, the reliability of the connection of the spring string can be improved, which is beneficial to extending the service life of the spring string and enhancing the support effect of the mattress.
[0040] For example, as Figure 3 shown, each spring string has two string spring wires 2, and the two string spring wires 2 are arranged on the upper and lower sides of the knotted spring 1, thereby further improving the reliability of the connection of the spring string, which is beneficial to extending the service life of the spring string and enhancing the support effect of the mattress.
[0041] In some embodiments, in the projection plane orthogonal to the axial direction of the knotted spring 1, the first knotting parts 111 and the second knotting parts 121 of a plurality of knotted springs 1 are arranged in sequence along the first direction (such as Figure 5 the A direction in Figure 5 ), the string spring wire 2 is arranged on one side of the knotted spring 1 along the second direction (such as Figure 3 the B direction in
[0042] ), and the first direction, the second direction and the axial direction of the knotted spring 1 (such as
[0043] the up and down direction in Figure 4 and Figure 5 are pairwise orthogonal.
[0044] For the mattress according to an embodiment of the present utility model, since the first knotting portion 111 and the second knotting portion 121 are arranged at intervals along the circumferential direction of the knotted spring 1, when the knotted spring 1 is subjected to an axial compressive force, the first spring coil 11 and the second spring coil 12 can be more evenly stressed. Compared with the solution of arranging the first knotting portion 111 and the second knotting portion 121 on the same side of the knotted spring 1, the phenomenon of the knotted spring 1 tilting when stressed can be avoided, the stability of the knotted spring 1 when stressed can be better, which is beneficial to improving the support effect of the mattress and enhancing the user experience.
[0045] As Figure 4 and Figure 5 shown, the mattress of another embodiment of the present utility model includes a plurality of spring strings, the spring strings are the spring strings of the present utility model, and the plurality of spring strings are arranged in sequence along the second direction to form a bed net 3, and the first direction, the second direction and the axial direction of the knotted spring 1 are pairwise orthogonal.
[0046] For the mattress according to an embodiment of the present utility model, since the first knotting portion 111 and the second knotting portion 121 are arranged at intervals along the circumferential direction of the knotted spring 1, when the knotted spring 1 is subjected to an axial compressive force, the first spring coil 11 and the second spring coil 12 can be more evenly stressed. Compared with the solution of arranging the first knotting portion 111 and the second knotting portion 121 on the same side of the knotted spring 1, the phenomenon of the knotted spring 1 tilting when stressed can be avoided, the stability of the knotted spring 1 when stressed can be better, which is beneficial to improving the support effect of the mattress and enhancing the user experience.
[0047] On the other hand, compared with the solution of the mattress "using the knotted spring 1 with the knotting portions arranged on the same side", the solution of the mattress according to the embodiment of the present utility model can facilitate the machine assembly of the mattress, and there is no problem of the orientation of the knotting portions of the knotted spring 1, which simplifies the production process and related equipment of the mattress and is beneficial to improving the production efficiency of the mattress.
