[0001]

[Industrial applications]

  This school plan relates to the improvement of cushion sheets for mattresses.

[0002]

[Prior art]

  Using urethane foam and coil spring together, coil spring As a cushioning sheet for mattresses that operate independently, Japanese Patent Publication Sho 53- The coil spring of No. 5587 is embedded in the sheath, and each coil spring is independent. It is composed of a predetermined elastic member so as not to interfere with proper operation, and the bottom ba Sufficient web to keep each sheath in the proper position and prevent deviations Only a part of the bottom of the web is connected to each other by the connecting member, There was a material and a sheath made of the same material.

[0003]   This certainly means that each coil sling can operate independently of the load. It is possible to support and fit the body.

[0004]   However, there were some problems in producing the above. Well Instead, to embed the coil spring by embedding it in urethane once, How to keep the coil spring hollow? In addition, mutual coil springs By urethane foaming, only part of the bottom was connected by urethane Since it is in a state, mutual coil springs before urethane foaming Is not connected, so it can be used for positioning and arranging coil springs in the foam mold. It took a lot of man-hours, was not suitable for mass production, and was expensive.

[0005]   The coil spring operates independently of the load until the final compression. Therefore, the cushioning property of the waist is weak, and the body with a heavy load is Deflection increases at the waist and the waist sinks deeply, making the sleeping posture worse. There was a flaw.

[0006]

[Problems to be solved by the device]

  The problem to be solved is that the coil springs are independent until the final compression. Of the coil spring and the fixed position in the foam mold of the coil spring. This is a point that many man-hours are required.

[0007]

[Means for Solving the Problems]

  In the configuration of the present invention, a plurality of morning glory coil springs (1) (1 ') ... Winding diameter of the adjacent morning glory coil springs (1) (1 ') ... Portion (2) (2 ') .... Connect the doshi with helical springs (3) (3'). Tied together to form a rectangular spring seat (4), and a morning glory coil spring (1 ) The maximum winding diameter portion (2) (2 ') ..., which is the connecting side of (1') ... About half the height of the pulling sheet (4) is embedded in another elastic cushion body (5). This is a cushion sheet for a mattress.

[0008]

[Action]

  In the present invention, the spring seat (4) has the morning glory coil spring (1 ) (1 ') ... ・ Maximum winding diameter part (2) (2') ... Since the small winding diameter parts (6) (6 ') ... Until they contact the elastic body (5), they operate independently and the elastic cushion body ( 5) For the load after coming into contact with the Load is distributed to the morning glory coil springs (1) (1 ') ... To do.

[0009]

【Example】

  FIG. 1 shows a cross section of one embodiment of the present invention. (4) is the maximum winding diameter part of a plurality of morning glory coil springs (1) (1 ') ... (2) (2 ') ... ・ Only the sides are connected by helical springs (3) (3') ... The minimum winding diameter part (6) (6 ') ... Side is not connected and it is not connected to the load. Each works independently.

[0010]   The elastic cushion body (5) is a foam made of soft urethane foam, and is placed in the foam mold. With a pulling sheet (4) installed, it is foamed with the height compressed to about half. is there. This elastic cushion body (5) is limited to a foam of soft urethane foam. It is not a thing, but another foam or urethane chip with the same performance is hardened. I don't care.

[0011]   FIG. 2 is a perspective view showing the whole structure of FIG. 1, showing the individual morning glory coil springs. About half of the height of (1) (1 ') ... projects from the elastic cushion body (5). , Cushion springs (1) (1 ') ... The cushioning properties are different before and after contacting the body (5).

[0012]   FIG. 3 is a sectional view showing another embodiment of the present invention, in which a spring seat (4 ) Is a Bonnel coil spring (7) (7 ') ... With a plurality of morning glory coil springs (1) (1 ') ... Arranged horizontally, the maximum winding diameter portion (2) of the morning glory coil springs (1) (1 ') ... ) (2 ') side and Bonnell coil spring (7) (7') ... Connect them with le springs (3) and (3 '), and fix the frame lines (8) and (8') to the upper and lower outer circumferences. This spring seat (4) is connected to the other side up to about half the height. It is embedded in the sex cushion body (5).

[0013]   The outer periphery of the spring seat (4) is attached to the Bonnel coil springs (7) (7 '). ) ..., and the frame line is fixed to the outer circumference because the outer peripheral portion is splined against the load. When the rings operate independently, the body easily slides down, enhancing elasticity. This is because

[0014]

[Effect of device]

  Prior to foam molding as in Japanese Patent Publication No. 53-5587, the present invention, Coil springs are not independent, but one side is connected to form a sheet Therefore, the troublesome work of positioning and arranging the individual springs in the molding die is possible. It is no longer needed, and the spring seat (5) can be installed in the mold, which reduces the number of work steps. Mass production is possible without any.

[0015]   In the present invention, one side of the spring seat (4) is connected and the other side is connected. And the connected side is embedded in the elastic cushion body (5) to about half the height. Since it is the one that has come into contact with the elastic cushion body (5) against the load, The coil springs operate independently and come into contact with the elastic cushion body (5). After that, the elastic cushion body (5) and other coil springs are activated. Since it shows a strong cushioning of the lower back, it is a heavy part of the body You can keep your body in an ideal sleeping position without deep depression.
