Description

  The present invention relates to a mattress cover structure using a side ground covering a core material.

  Conventionally, a mattress used when a user sleeps is used by being placed on a placement surface such as a bottom or a floor of a bed. For such mattresses, various proposals for improving the comfort and safety of users have been made.

  For example, as shown in FIG. 14, in the case of a bed apparatus that can be raised, when the mattress 11 lifts and raises the back of the user 10 by a back raising operation, the mattress 11 has a bent portion 13 of the cushion portion 12. Since the upper surface side of this is compressed and shortened in the longitudinal direction, a force for pressing the user's back in the lower body direction is generated as indicated by an arrow in the figure. In addition, since the upper surface side of the bent portion 13 of the cushion portion 12 is compressed and shortened in this way, the side ground 14 is loosened at this portion, and the heel 15 is generated, and the sleeping comfort is deteriorated.

  The user 10 is pressed and displaced in the foot direction by the pressing force described above, and a frictional force acts between the upper surface of the mattress 11 and, therefore, a pressure ulcer in the body part, particularly in the back part or the heel part. There was a problem of causing the occurrence.

  Therefore, various countermeasures have been proposed in the past in order to reduce the generation of such force applied to the user.

  As a conventional technique, for example, a cover configured to cover at least the upper surface of a mattress is provided with a slippery sheet, and the user's back is displaced with low friction by the seat in a back-up operation, whereby the force applied to the user In order to reduce this, a proposal has been made (see Patent Document 1).

JP-A-9-266829

  However, according to the technique of Patent Document 1 described above, since the cover provided with the slippery sheet is a separate member from the mattress, handling is troublesome, and the mattress itself is the upper surface of the portion where the cushion portion is bent. When the side is compressed and shortened in the longitudinal direction, the side ground may be loosened and wrinkles may occur at the site. Thereby, there exists a problem that the deterioration of the sleeping comfort by the side heel will arise.

  The present invention has been made in view of the above-described conventional problems, and provides a mattress cover structure capable of reducing wrinkles generated in a side ground when a user moves when using the mattress. With the goal.

  The mattress cover structure according to the present invention for solving the above-described problems is as follows.

The present invention is a mattress cover structure, in a mattress cover structure configured to cover a core material with a side ground,
An inner cover member covering the outer periphery of the core material;
The side ground is configured to cover the inner cover member,
A surface of the inner cover member is provided with a friction region having a friction function,
The inner surface of the side ground is provided with a friction region that generates a specific friction function by contacting with the friction region of the inner cover member.

  According to the mattress cover structure of the present invention, in the mattress cover structure configured to cover the core material with the side ground, the mattress cover structure includes an inner cover member that covers an outer periphery of the core material, and the side cover covers the inner cover member. A friction region having a friction function is provided on the surface of the inner cover member, and a specific friction function is generated on the inner side surface of the side ground by contacting the friction region of the inner cover member. By providing a friction area, when using the mattress, the frictional action generated between the side ground and the inner cover member is reduced, so that the side ground does not go against the inner cover even if the user moves. Since it becomes easy to follow a movement, the wrinkle which arises in a side ground can be reduced.
