Description

  The present invention relates to a pocket coil sheet in which a coil is enclosed in a bag, and is improved so that the coil spring can be easily taken out when the spring unit is discarded or disassembled.

  A conventional sheet is a pocket coil sheet having a spring unit in which a coil is encapsulated in a bag, and is provided with a rupture portion weak in strength at a part of the bag, and the rupture portion is broken when the spring unit is disassembled. Thus, as an example, a bag row in which pocket coils were individually enclosed in a plurality of continuous bags was welded by thermal welding to form a rectangular pocket coil sheet. In that case, the pocket coil sheet had a fractured portion on the upper or lower surface.

Japanese Patent Laying-Open No. 2005-65726 (page 2-11, FIGS. 1 to 17)

  A conventional sheet is a rectangular pocket coil sheet in which a plurality of continuous bags enclosed in a plurality of continuous bags are welded together to form a rectangular pocket coil sheet. Each has a broken portion, and the broken portion is not continuous between adjacent bag rows, and therefore must be disassembled for each coil row at the time of disassembly or disposal. Since there are no protrusions on the pocket coil sheet, the top surface of the pocket coil sheet must be pressed so that the pocket coil sheet does not move when disassembling, and the pressing position must be moved sequentially during disassembly. It took time and effort.

  The pocket coil sheet unit of the present invention bonds bag rows (3, 3a...) Formed by individually enclosing pocket coils (2, 2a...) In a plurality of continuous bags (1, 1a...). In a fixed rectangular coil coil sheet (4), a presser margin (6, 6a, 6b) is bonded to the lower surface of the pocket coil sheet (4), and the presser bar (6, 6a, 6b). Protrudes from the width direction (7) of the pocket coil sheet (4) and, as shown in FIGS. 2 and 3, below the bonding portions (8, 8a...) Of the individual bags (1, 1a...). It has a large number of through holes (9, 9a...) In a row.

  The pocket coil sheet unit of the present invention is a pocket coil sheet (4) of a spring unit in which pocket coils (2, 2b...) Are enclosed in bags (1, 1a...) As shown in FIGS. Are provided with through holes (9, 9a...) Below the bonding portion (8) of the bag (1, 1a...), And the presser margin (6) is bonded and protruded in the width direction (7). When the coil sheet (4) is disassembled, the presser margins (6, 6a, 6b) are held by heavy objects (10, 10a), grasped from the upper surface side of the pocket coil sheet (4) by the dismantling device (11), and pulled. The grasped portion of the bag (1, 1a ...) is separated from the through hole (9, 9a ...), and the bag (1, 1a ...) adjacent to the separated upper bag (1, 1a ...) and the adhesive portion ( 8), the adjacent bags (1, 1a... It will be pulled up, and can be separated successively adjacent bags (1, 1a ...). This facilitates the removal of the pocket coil (2, 2a ...) from the bag (1, 1a ...), improves the disassembly of the spring unit at the time of disposal, and saves time and labor at the time of disassembly. Separation of the coil and the bag becomes easy, and there is a great practical effect that the recyclability is improved.

  Further, by providing a large number of through holes (9, 9a...) Below the bonding portion (8) of the bag (1, 1a...), The air permeability of the pocket coil sheet (4) is also exerted.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the pocket coil sheet (4) of the present embodiment has pocket coils (2, 2a,...) Independently in bags (1, 1a,...) Made of a plurality of continuous non-woven fabrics. Enclosed, adjacent bag rows (3, 3a...) Are bonded to each other and formed into a rectangular pocket coil sheet (4). The pocket coil sheet (4) has a length direction (5) and a width direction (7) of the bottom surface of one end, and a press margin (6) made of a nonwoven fabric is bonded to the end. The press margin (6) As shown in FIG. 2 and FIG. 3 below the adhesive portions (8, 8a...) Of the individual (1, 1a...) Projecting from the width direction (7) of the pocket coil sheet (4), 9, 9 a...) In a row. As shown in FIG. 2 and FIG. 3, the through holes (9, 9a,...) And the presser margin (6) are bonded below the bonding portions (8, 8a,...) Of the bags (1, 1a,. By projecting in the width direction (7), the pocket coil sheet (4) is held by the heavy load (10, 10a) when the pocket coil sheet (4) is disassembled, and the bag (1, 1a ...) is held by the dismantling device (11) or the like. The bag (1, 1a ...) of the portion gripped by pulling is separated from the through hole (9, 9a) and is adhesively connected to the bag (1, 1a ...) adjacent to the separated upper bag. Therefore, the adjacent bags (1, 1a,...) Are pulled up, and the adjacent bags (1, 1a,...) Can be sequentially separated. When the pocket coil sheet (4) is disassembled, the pocket coils (2, 2a...) Can be easily taken out from the bag (1, 1a...), And the disassembly of the spring unit is improved when discarded.

  Hereinafter, embodiments of a presser bar used at the time of disassembly will be described with reference to the drawings.

  In the present embodiment, as shown in FIG. 4, the presser margin (6, 6a) made of a nonwoven fabric is provided in the pocket coil sheet (4) in the length direction (5) and the width direction (7) of the lower surfaces at both ends. It is glued in a protruding state from the coil sheet (4). When disassembling, the presser margin (6, 6a) is pressed by a heavy object (10, 10a), and the bag (1, 1a,. The pocket coil sheet (4) can be fixed more efficiently than when the presser margin (6, 6a) is bonded in the length direction (5) and the width direction (7) at the bottom of one end. It has the advantage that it can be decomposed in a stable state.

  In the present embodiment, as shown in FIG. 5, the presser margin (6) made of non-woven fabric at the length direction (5) both ends of the bottom surface and the width direction (7) end portion of the center bottom surface of the pocket coil sheet (4) , 6a) are bonded in a protruding state from the pocket coil sheet (4), and the presser margins (6, 6a, 6b) are held by heavy objects (10, 10a) when disassembled, and the bags (1, 1a,. ) Can be efficiently disassembled by grasping with a dismantling device (11), etc., and compared with the case where the presser margins (6, 6a) are bonded in the length direction (5) and the width direction (7) of the bottom surfaces of both ends The sheet (4) can be fixed, and has an advantage that it can be disassembled in a stable state.

  In the present embodiment, as shown in FIG. 6, presser margins (6, 6 a) made of nonwoven fabric are provided on both sides of the lower surface in the length direction (5) of the pocket coil sheet (4). 4) Adhered in a protruding state. When disassembling, the presser margins (6, 6a) are pressed by heavy objects (10, 10a), and the bags (1, 1a,...) Are held by the dismantling device (11) or the like. The pocket coil sheet (4) can be more efficiently fixed than when the presser margins (6, 6a) are bonded in the length direction (5) at both ends of the lower surface and in the width direction (7) of the central lower surface. It has the advantage that it can be decomposed in a stable state.

  In the present embodiment, as shown in FIG. 7, a presser margin (6) made of a nonwoven fabric is bonded to the bottom surface of the pocket coil sheet (4) in a protruding state from the pocket coil sheet (4). Since the bottom surface of the pocket coil sheet (4) can be firmly fixed to the surface by pressing the presser margin (6) with a heavy object (10, 10a) during disassembly, the bag (1, 1a ...) is disassembled. It can be efficiently disassembled by grasping with the device (11) etc., and the pocket coil sheet (4) more than when the presser margin (6) is bonded on both sides of the width direction (7) in the length direction (5). Can be fixed and can be decomposed in a stable state.

  Hereinafter, one example of disassembly of the pocket coil sheet will be described with reference to the drawings.

  The presser margin (6) protruding in the width direction (7) of the pocket coil sheet (4) is a heavy object (10, 10a) that can fix the pocket coil sheet (4) when disassembled as shown in FIG. Place it on the part of the presser bar (6) that protrudes from the pocket coil sheet (4), fix the pocket coil sheet (4), and then use the tilt-type fork claw (11), etc. The pocket coil sheet (4) can be easily disassembled by grasping and pulling from the upper surface side of the coil sheet (4).

  The pocket coil sheet unit of the present invention is mainly used for a mattress pocket coil sheet, but can be similarly applied to a pocket coil sheet for a sofa or a sofa bed.
