Claims (8)

  1. 1. A mattress having pocketed springs, comprising: a coil spring forming the pocketed spring; 1 st cloth forming a pocket space for accommodating the coil spring, and A2 nd cloth extending in a plane shape to cover the whole of the bag space, One of the 1 st cloths is arranged in each column with respect to the column of bag spaces, The 1 st cloth has, on both sides with respect to the center of the plurality of bag spaces, stitches continuous in the 1 st direction, The 2 nd cloth is fixed at a portion between 2 of the thread pins of the 1 st cloth, which is the same portion between 2 of the thread pins in the 2 nd direction crossing the 1 st direction, The 2 nd cloth has a slit along the 1 st direction, The stitch is formed in such a way that it breaks when the portion of the 1 st cloth is pulled in a direction away from the bag space.
  2. 2. The mattress of claim 1, wherein, The slit extends from one end portion to the other end portion of the 2 nd cloth in the 1 st direction.
  3. 3. The mattress of claim 1 or 2, wherein, In the 2 nd direction crossing the 1 st direction, a plurality of slits are provided in a manner separated from each other, The slit is formed between predetermined columns adjacent to each other in the 2 nd direction among the plurality of columns in a plan view.
  4. 4. The mattress of claim 1, wherein, The stitch is formed at a position more biased toward the 2 nd cloth side with respect to the center of the coil spring in the axial direction in the up-down direction.
  5. 5. A method of manufacturing the mattress of any one of claims 1 to 3, comprising: A step of fixing the 2 nd cloth to the 1 st cloth, and And forming the slit in the 2 nd cloth fixed to the 1 st cloth.
  6. 6. A method of manufacturing the mattress of any one of claims 1 to 3, comprising: a preparation step of preparing the 1 st cloth having the stitch; a step of positioning the centers of the coil springs in a row of the bag spaces at the center between the thread feet in the 2 nd direction on one of the 1 st cloth, and And a step of covering the coil spring with the 1 st cloth by overlapping the 2 nd ends of the 1 st cloth with each other.
  7. 7. The manufacturing method according to claim 6, wherein, The preparation step includes a step of forming the stitch while cutting one cloth for forming the plurality of 1 st cloths into a plurality of pieces.
  8. 8. A discarding method of discarding the mattress of any one of claims 1 to 3, comprising: A1 st step of breaking the 1 st cloth by peeling the 2 nd cloth from the 1 st cloth and using the stitch, and And a step 2 of taking out the coil spring from the bag space opened as the 1 st cloth is broken after the 1 st step.

Description

Mattress, manufacturing method and discarding method Technical Field The present disclosure relates to a mattress, a method of manufacture, and a method of disposal. Background Mattresses are known which implement pocketed springs by housing coil springs in pockets forming pocket spaces. In such a mattress, there is also known a technique in which the side portions of the bag-like bodies of the respective coil springs are joined to each other, the leg portions are formed along the body-surrounding directions of the respective bag-like bodies, and the upper surfaces of the bag-like bodies are bonded to the lower surfaces of the mounting units by using an adhesive (for example, refer to patent document 1). According to this technique, by pulling the mounting unit upward, the leg of the bag-like body can be broken, and the upper surfaces of the bag-like bodies are all opened, so that the coil spring can be easily removed. < Prior art document > < Patent document > Patent document 1 (Japanese patent application) JP 2012-95785A Disclosure of Invention < Problem to be solved by the invention > However, according to the above-described conventional technique, it is necessary to cut one piece of cloth and form a pocket for each coil spring, and thus the manufacturing cost increases. In addition, since the bag-like bodies are formed separately, assembly errors are likely to occur when a plurality of bag-like bodies are arranged. This assembly error is caused by the fact that the breakage of the thread is not generated in a part of the bag-like body, and the whole is affected, and thus the desired mode of simultaneously breaking all the thread may not be realized. On the other hand, if a plurality of bag spaces are formed without cutting one piece of cloth, it is possible to solve some of the above-described problems when forming the bag-like bodies, but since the plurality of bag spaces are connected to each other by the cloth, it is difficult to form the leg portions that can easily open the plurality of bag spaces. In view of this, an object of the present disclosure is to form a plurality of bag spaces in a mattress without cutting one piece of cloth, and to form a stitch capable of easily opening the plurality of bag spaces on the cloth. < Means for solving the problems > In one aspect of the present invention, there is provided a mattress having a pocketed spring, including a coil spring forming the pocketed spring, 1 st cloth forming a pocket space for accommodating the coil spring, and 2 nd cloth extending in a planar shape to cover the entirety of the pocket space. The 1 st cloth is provided for each column of the bag spaces, the 1 st cloth has a stitch continuous along the 1 st direction on both sides with respect to the center of the plurality of bag spaces, the 2 nd cloth is fixed at a portion between 2 of the stitches on the 1 st cloth and between 2 of the stitches in the 2 nd direction intersecting the 1 st direction, and the stitches are formed in such a manner that the stitches are broken when the portion of the 1 st cloth is pulled in a direction away from the bag spaces. < Effect of the invention > According to the present disclosure, in a mattress, a plurality of bag spaces can be formed without cutting one piece of cloth, and a stitch that can easily open the plurality of bag spaces is formed on the cloth.
