Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a pinerest with a built-in air pine.

(Prior art) The applicant, in Utility Model Publication No. 56-54828,
A mattress has been disclosed in which a semi-hard elastic material and a soft elastic material are sequentially polymerized on at least one of the upper and lower surfaces of a flat air mat, and the polymer is covered with an exterior material. This pine tress was successful because it was cheaper and lighter than pine tresses manufactured by paralleling coil springs.

However, this pinerest had the disadvantage that the firmness could not be adjusted and the cushioning properties could not be changed arbitrarily. Therefore, the inventor researched a pine tress that could adjust the firmness and change the cushioning properties.

(Problems to be solved by the invention) This invention was made based on the above circumstances, and its purpose is to provide a pinerest with a built-in air pine whose firmness and cushioning properties can be adjusted according to the user's preference. This is what I am trying to do.

[Structure of the idea]

(Means and effects for solving the problems) This invention to solve the above problems consists of a flat air mat, a box-like base that houses the air mat, and a box-like base that covers these and that can be opened and closed at least partially. The hardness and cushioning properties can be set arbitrarily according to the user's preference by installing a removable plate material on the air mat surface to adjust the hardness and cushioning properties. can.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings. This mattress is composed of an air mat 1, a box-shaped base 2 surrounding the lower surface and four circumferential sides of the air mat 1, and an exterior body 3 covering the air mat 1 and the box-shaped base 2.

The air mat 1 has partition pieces 11 inside,
The partition piece 11 is provided so as to form a bag portion whose volume gradually decreases toward the edge of the air mat 1. That is, the central bag portion 1
The cross-sectional area becomes smaller as 1b and 1c extend outward from a. A stopper 12 is attached to each of the bag portions 1a, 1b, and 1c.

The box-like base body 2 consists of a bottom part 2a and a side wall part 2b, and the bottom part 2a is covered with a cushioning material 21 such as felt or nonwoven fabric.
A protective material 22 such as a semi-hard sisal pad or pressed palm is polymerized and bonded to a soft elastic material 23 such as urethane foam, and the side wall portion 2b is made of a semi-hard foamed elastic material and surrounds the peripheral side of the air mat 1. , its lower end surface 24 is adhesively fixed to the peripheral edge of the bottom portion 2a and is erected. An engaging stepped portion 25 is cut out over the entire circumference of the upper end surface of this side wall portion 2b, and a plate-shaped body 4 is inserted into this engaging stepped portion 25 for adjusting the hardness of the pinerest. . In this embodiment, the semi-rigid material 2 is preferably a soft urethane foam, but a hard synthetic resin network may be used if necessary.

The box-shaped base body 2 has a semi-rigid foamed elastic body for the side wall portion 2b, so when the air mat 1 is inflated, the foamed elastic body absorbs the bulge in the side part by denting, so that the side part of the pinerest does not bulge out and is in a rectangular state. I try not to break it.

Since the side wall portion 2b is provided with an engaging step portion 25 cut out inwardly on the upper end surface, the plate-like body 4 for adjusting the hardness and cushioning properties is engaged with the engaging step portion 25. It is stopped and horizontal movement is prevented.

The bottom part 2a of the box-shaped base 2 is made by polymerizing and bonding a cushioning material 21 such as felt or nonwoven fabric, a protective material 22 such as semi-hard sisal pad or pressed palm, and a soft elastic material 23 such as urethane foam in order from the inner surface side. Therefore, the soft cushioning material 21 such as felt or non-woven fabric can prevent damage caused by contact with the air mat, and the semi-hard sisal pad,
Since the protective material 22 such as pressed palm is made of a material with a coarse mesh and good breathability, the poor ventilation which is a drawback of the air mat 1 can be corrected.

The exterior body 3 consists of upper and lower mirror parts 31 and 32 and a side wall part 33, and the upper mirror part 31 is detachably attached to the box-shaped base 2 by a fastener 34 at the upper end of the gore part 33.
It serves as a cover body, facilitates repair and replacement work of the air mat 1, and also allows the plate-like body 4 to be taken in and out freely. The mirror parts 31 and 32 are made of soft cotton or urethane foam, quilted and sewn together with the exterior material, and have heat retention and breathability. When a user lies down on the upper mirror section and the lower mirror section, the firmness and cushioning properties are different.

[Effect of idea]

As described above, according to this invention, there is a flat air mat, a box-shaped base that houses the air mat, an exterior body that covers these and can be opened and closed at least in part, and a hard plate on the surface of the air mat. , a plate-like body for adjusting cushioning properties is provided in a removable manner, and the box-like base body is sequentially covered with cushioning materials such as felt or nonwoven fabric, semi-rigid sisal pads, and press palm from the inner side. A protective material such as the like and a soft elastic material such as foamed urethane foam are polymerized and bonded to the bottom part, and the bottom part is fixed by adhesion to the peripheral edge of the bottom part, and the engagement step part is cut out inwardly on the upper end surface. The box-shaped base has side walls made of a semi-hard foamed elastic material, so the user can change the hardness and cushioning properties of the pinerest according to his or her preference. Since it is made of a semi-rigid foamed elastic body, when the air mat is inflated, the bulge on the sides is absorbed by concaving the foamed elastic body to prevent the pine tress from collapsing in its rectangular shape.

Since the engagement step portion is cut out toward the inner side of the upper end surface, a plate-like member for adjusting hardness and cushioning properties can be locked to this engagement step portion.

The bottom of the box-shaped base is made of a cushioning material such as felt or non-woven fabric, a protective material such as semi-hard sisal pad or pressed palm, and a soft elastic material such as urethane foam, which are polymerized and bonded in order from the inner surface. Damage to the air mat can be prevented with cushioning materials such as , non-woven fabric, etc., and protective materials such as semi-hard sisal pads and pressed palms can correct poor ventilation caused by the air mat.
