早期に損なわれるという欠点があつた。(Problems to be Solved by the Invention) Conventionally, in a spring device having such a configuration, the spring portions of the main spring and the intermediate support spring were formed in a torsion spring portion. The torsion spring portion is formed of a plurality of torsion rod portions spaced apart in parallel in the vertical direction, and a plurality of connection rod portions each having both ends connected to one end of the pair of upper and lower torsion rod portions. When a compressive load is applied, the connecting rod rotates and twists the torsion rod. Such a torsion spring part is
Compared to a helical spring section, which receives most of the load by bending the wire rod, the amount of deflection with respect to the load is smaller, so the spring device can be made stiffer. On the other hand, since permanent strain is likely to occur in the torsion rod portion, there is a drawback that the cushion undergoes a large amount of wear with use, and the cushion performance as a spring device is quickly impaired.

とがなく、有効に利用することが出来る。 According to the spring device having such a structure, the main spring 3 has helical spring parts 8 at both ends of the connecting rod part 7, which are less likely to undergo permanent strain due to use.
The main spring 3 maintains its cushioning properties over a long period of time. Furthermore, since the intermediate support spring 4 has torsion spring parts 10 formed at both ends of the connecting rod part 11 with a small amount of deflection against the load, the connecting rod part 7 of the main spring 3 is supported with hard elasticity, and the user can The intermediate support spring 4 supports the user together with the main spring, but the proportion of support for the user by this intermediate support spring 4 is large. Therefore, the connecting rod portion 7 of the main spring 3 is difficult to bend under the load, thereby preventing the heavy part of the user's body from sinking deeply. Further, since the spring portion of the intermediate support spring 4 is the torsion spring portion 10, the permanent strain that occurs due to long-term use is greater than that of the helical spring portion 8, and good cushioning performance is likely to be lost. Support spring 4
Even if the cushioning properties of the torsion spring portion 10 of the main spring 3 are impaired, the cushioning properties of the helical spring portion 8 of the main spring 3 are maintained over a long period of time. It won't cause any major damage. Further, since the corner portions of the spring device are reinforced with corner springs, even if the user is located at the corner portions, the corner portions do not sink significantly and can be used effectively.

とが出来るなどの利点を有する。(Effects of the invention) As described above, this invention makes the spring parts formed at both ends of the connecting rod part of the main spring a helical spring part, and the intermediate support spring that elastically supports the connecting rod part of the main spring. The spring portions formed at both ends of the connecting rod portion are torsion spring portions, and further,
A corner spring having a torsion spring portion is provided at the corner portion. Therefore, since the helical spring portion of the main spring does not easily wear out due to long-term use, the cushioning properties of the main spring are maintained over a long period of time. In addition, since the intermediate support spring supports the connecting rod portion of the main spring with strong elasticity through its torsion spring portion, the connecting rod portion of the main spring bends greatly against the load, causing a part of the user's body to sink deeply. prevent it from happening. Furthermore, even if the torsion spring portion of the intermediate support spring undergoes permanent strain and its cushioning properties deteriorate due to long-term use, the helical spring portion of the main spring is unlikely to deteriorate, so the cushioning properties of the spring device as a whole are improved. maintained. Furthermore,
Since the corner portions are formed hard, there is an advantage that even if a user is located at or near the corner portions, the corner portions do not sink significantly and can be used effectively.
