Reference numeral 00 denotes a set of springs 1 alone. The spring unit 1 has a plurality of annular members 2 each formed of a flange-like body arranged in parallel up and down with its central axis being one. The illustrated example comprises an intermediate annular member 2C provided between the upper end annular member 2U and the lower end annular member 2D. The upper and lower end annular members 2U, 2D have a large diameter to improve stability, and the intermediate annular body 2C has a slightly smaller diameter, and connects the annular members 2U, 2D, 2C and the annular members 2U, 2C, 2D, which will be described later. The outer peripheral edge of the connecting member 4 forms a substantially drum-shaped virtual cylindrical surface 3.

An elastic connecting member 4 having a U-shape (U-shape) is provided, and the annular members 2U, 2C, 2D and the elastic connecting member 4 are integrally formed. The portion where the elastic connecting member 4 is connected to the upper and lower annular members 2U and 2D is bent in an L shape in a side view, and the outer edge of the bent portion is used as a contact surface 6 with a joint fixing member 5 described later.

When U and 2D are bent most, the contact surface 6 comes into contact with the receiving surface 7 of the joint fixing member 5 to prevent further compression. Further, the upper and lower annular members 2U and 2D are provided with arch-shaped notches 10 so that the U-shaped bent portion of the elastic connecting member 4 does not come into contact when the elastic connecting member 4 is bent most. The joint fixing member 5 is a block protruding from the front side of the virtual cylindrical surface 3 and having a flat receiving surface 7 on the upper and lower sides, and has an insertion hole 9 for a joint 8 formed in the front surface. The insertion hole 9 penetrates to the back of the joint fixing member 5.

系,ポリアセタール系の樹脂を用いる。The whole spring 1 is integrally formed of a synthetic resin material and is basically formed using a mold. As the resin material used for the spring 1, a material having excellent bending strength and particularly strong in repeated bending stress is suitable. For example, a polypropylene-based, polyamide-based, or polyacetal-based resin is used.

撓曲され、スプリング単体1は全体として上記圧縮荷重
に見合った弾性変形量だけ圧縮されて平衡状態となる。When a compressive load (equally distributed load) is applied to the single spring 1 constructed as described above, each elastic connecting member 4 is bent in a direction to narrow the interval of the inverted U-shape, and the single spring is formed. 1 as a whole is compressed by an elastic deformation amount commensurate with the above-mentioned compressive load to be in an equilibrium state.

る。When an excessive compressive load P exceeding the limit of the shape elastic deformation is applied to the spring 1, the contact surfaces 6, 6 of the upper and lower elastic connecting members 4, 4 are respectively formed in the intermediate annular shape. By contacting the receiving surface 7 of the joint fixing member 5 of the member 2C, further elastic deformation is restricted.

It is possible to prevent the support state from becoming unstable or being damaged due to the difference between the outside and the inside, thereby obtaining a stable support state. Note that the joint fixing member 5 may be formed over a wider range as long as the positions of the insertion holes 9 are provided at 120 ° intervals. Further, the joint fixing member 5 is formed in a flange shape over the entire circumference of the annular member 2. You may.

As shown in FIG.
The connection method is described below. First, as shown in FIG. 1, the tops of the joint fixing members 5 of the two springs 1A and 1B are positioned so as to face each other, and the short arms 11 and 12 of the joint 8 are inserted into the insertion holes 9 of the joint fixing members 5 facing each other. The remaining long arm 13 is fitted into the insertion hole 9 of the joint fixing member 5 of the spring unit 1C in which the spring unit 1A, 1B is arranged in a triangular shape together with the spring unit 1A. The springs 1A, 1B, 1C are fixed to the springs. The fitting between the joint 8 and the joint fixing member 5 is performed by inserting the hook 15 at the tip of the leg into the insertion hole 9 of the joint fixing member 5 while narrowing the hooks 15 at the tip of the arm by the cut 14. The hook 15 at the tip of the leg is locked to the inner wall of the joint fixing member until it comes out of the hole 9. By repeating this, the number of connected springs alone is increased to an appropriate number.

る。As described above, the mattress spring of the present invention is connected so as to have a desired shape and size as a mattress, and the connection is made by a joint 8 provided at an intermediate position in the vertical direction of the spring. Therefore, the annular members 2U and 2D at the upper and lower ends of the spring are completely free. Therefore, when downward pressure is applied to the upper and lower annular members 2U and 2D of the springs, the individual springs are deformed downward by the pressure applied to each of the springs. It does not affect the deformation of the spring itself, and each spring deforms independently according to the force received by the machine frame, so when used as a mattress, it faithfully follows the distribution of human body weight Allows to receive weight with deformation along. Further, since the individual springs 1 are connected by the jotent 8, if the arm length of the joint 8 is changed as appropriate, the interval between the springs 1 can be changed sparsely and appropriately.
