However, conventional bed mattresses are unable to disperse body pressure well depending on the weight and physique of the user, and are unable to support movement such as turning over well, and thus are uncomfortable. There's a problem.
This is because only the pocket coils having the same elasticity are arranged side by side.

  For example, a bed mattress using a pocket coil having a strong elasticity is generally suitable for a heavy-weight user because it can sufficiently support the weight, but a light-weight user. It tends to be unsuitable for. On the other hand, a bed mattress using a pocket coil with low elasticity tends to be suitable for a light user, but not suitable for a heavy user.

  Therefore, an object of the present invention is to provide a bed mattress that is comfortable to sleep and is suitable for all users regardless of weight or physique.

In order to achieve the above object, the bed mattress according to claim 1 of the present invention is configured to accommodate one coil spring (S) having the same diameter in a cylindrical body (P) having the same size. A bed mattress (1) including a coil structure (10) formed by arranging a plurality of pocket coils (20) formed in close contact with each other in the horizontal direction,
The coil structure (10)
A plurality of first pocket coils (20a) formed by accommodating one first coil spring (S1) of elasticity X among the coil springs (S) in the bag body (P), in series. The arranged first coil group (11),
Among the coil springs (S), the bag body (P) is formed by housing one second coil spring (S2) having an elasticity Y different from the elasticity X of the first coil spring (S1). A plurality of second pocket coils (20b) arranged in series and a plurality of second coil groups (12) arranged alternately in a direction perpendicular to the longitudinal direction in which each coil group (11, 12) extends. ,
The first coil group (11) and the second coil group (12) are shifted from each other by the radial distance (D) of the first and second pocket coils (20a, 20b) in the longitudinal direction. The pocket coil is arranged so as to be positioned between two adjacent pocket coils of the other coil group.

  Further, in the bed mattress according to claim 2, each of the first coil groups (11) is connected by joining adjacent bag bodies (P) in series, and each of the second coils. Each of the groups (12) is characterized in that the bags (P) adjacent in series are joined together.

  Furthermore, the bed mattress according to claim 3, the adjacent first coil group (11) and second coil group (12) of the first coil group (11) and the second coil group (12), respectively. The bag bodies (P) are connected to each other by bonding.

  The bed mattress according to claim 4 is characterized in that the first coil group (11) and the second coil group (12) have a longitudinal direction of a longitudinal direction, a lateral direction, and an oblique direction of the bed. One of the directions is used.

  The bed mattress according to claim 5 is configured such that the first coil spring (S1) of the first coil group (11) and the second coil spring (S2) of the second coil group (12) are coiled. The elasticity is different depending on the number of turns or material.

According to the bed mattress of the second aspect, in addition to the function and effect of the invention of the first aspect, the first coil group and the second coil group are respectively adjacent in series. Since the bag bodies of the one coil and the second coil are connected to each other by joining, the first coil group and the second coil group can always be maintained in series with certainty.
Thereby, for example, even when the user performs a rollover or the like, the first coil group and the second coil group maintain their arrangement without shifting the first pocket coils and the second pocket coils, respectively. can do. This can also improve sleeping comfort.

  Furthermore, according to the mattress for bed of Claim 3, in addition to the effect of the invention of Claim 1 and 2, adjacent 1st coil group and 2nd coil group are between each bag body. Since they are connected by being bonded together, they can be maintained as they are without being displaced by the movement of the user. Therefore, the sleeping comfort can be further improved.

  According to the bed mattress of claim 4, the longitudinal direction of the first coil group and the second coil group is any one of the longitudinal direction, the lateral direction, and the diagonal direction of the bed. It can be so versatile.

  According to the bed mattress of claim 5, the first coil spring of the first coil group and the second coil spring of the second coil group have the same diameter, but the number of turns or the material of the coil is different. Since the elasticity can be made different according to the above, various things can be selected.
