JP2015036098A - Rubber mat storable by being rounded small - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a rubber mat capable of adjusting intensity of repulsion or hardness at a desired spot by restoring the rubber mat or a cushion rounded compactly and folded to a desired shape without air injecting by manpower.SOLUTION: A bag-shaped mat shaped or formed by welding and laminating a thin sheet-shaped material is formed by using a soft and highly restorable material (silicon rubber, synthetic rubbers, crude rubber, a synthetic resin or the like). When being stored, the mat can be reduced by being rounded and folded simply, and stopped by a lid and a stopper, and when being used, the air is taken naturally by restoring force of the rubber mat itself by removing the lid and the stopper, and the mat is restored to the original shape, and further by putting the lid on the inlet again, airtight sealing is achieved and the shape can be maintained. In addition, proper hardness and repulsion can be imparted to each portion of a body having a contact with the mat by adjusting the thickness of a formed rubber layer and the volume of an air space formed by the rubber layer.

Description

In this invention, the mat of the set shape can be folded (rolled and crushed) to be small when stored, and when used, the rubber material uses its own restoring force to swell without injecting air and return to its original shape. The present invention relates to a rubber mat that can be adjusted in hardness and resilience by the thickness of a rubber material and the thickness of an air layer.

Conventional mats (mattresses, cushions, etc.) that can be crushed and made small, as represented by a floating ring, were inflated by blowing air from the inlet or by an instrument into a bag-like mat with thin resin sheets welded together. The shape and repulsive force of the mat are maintained by sealing the injected air with a lid on the rear inlet. Adjustment of the repulsive force of the mat depends on the amount of air to be blown and the uneven shape of the surface.

However, in order to make the above-mentioned conventional mats into a shape to be used, a considerable amount of air must be injected, or they are blown manually or inflated by using a device such as a pump. However, it takes time and force to inflate manually, and when using equipment such as a pump, the equipment itself becomes bulky and it is difficult to carry it with a mat. Also, since the repulsive force obtained according to the amount of air blown into the entire bag-shaped resin sheet is almost uniform, it is difficult to adjust the hardness and repulsive force of each part of the body where the mat and the body come into contact. It is difficult to realize.

Patent Publication No. 2007-124202 It can be folded during travel, and it is convenient to carry, and it can be used as a pneumatic cushion, and a flexible resin sheet can be bonded to the cloth cover member by heat, and air can be blown from the valve. The air bag is housed, and air is injected into the air bag. After that, the plug is inserted into the valve opening so that it can be completely sealed. I can do it.

The air cushion is inflated into a shape that supports the legs and hips so that it can be used when air is sealed in the air bag stored in the cover member in claim 1. In addition, the repulsive force of the cushion depends on the amount of injected air because the thickness of the resin sheet is almost uniform, and the effect of surface irregularities is small, and it is difficult to adjust the partial hardness and repulsive force .

Problems to be solved by the invention

The air cushion of the prior art and Patent Document 1 must be spread once and then air must be injected from the inlet using a hand or instrument in order to make the small folded cushion into the desired shape. The resilience, hardness and softness of the cushion can be adjusted only by the amount of air injected and the uneven shape of the surface since the thickness of the resin sheet is almost uniform. It is difficult to adjust the strength of the force and it is difficult to obtain comfort that requires a cushion.
Therefore, the present invention provides a rubber mat that is compactly rounded and folded, and a rubber mat that can adjust the strength and resilience of the repulsive force at the required location without manually injecting air, and adjust the hardness. Let it be an issue.

Means for solving the problem

In order to solve the above problems, the rubber mat was folded using a material that was flexible, rolled and easy to fold, and that could easily be restored to its original shape (silicon rubber, synthetic rubber, raw rubber, synthetic resin, etc.) When the rubber mat stopper and lid are removed and the rubber mat is opened, the rubber mat is molded into a bag, or a sheet of material in a bag is welded and bonded together. The original shape set from the rounded and folded state can be restored. After restoration, the rubber mat inlet is re-capped to seal the air taken in the rubber mat and maintain the repulsive force. The required hardness, softness, and strength of the repulsive force can be adjusted by the mat rubber thickness (upper and lower layers and sides) and the volume of the air layer between the upper and lower rubber layers.

Effect of the invention

According to the present invention, the rubber mat that is folded in a flexible, small and rounded shape can be restored by removing the lid and the stopper that hold the folded state without manually injecting air. It can be restored to its original shape set in a short time with the air taken in, and the shape can be maintained by sealing the inlet with a lid in that state, maintaining the repulsive force and fulfilling the required rubber mat function. . The shape and size required for each purpose can be set for this rubber mat, and it can be placed under or attached to the whole body or a part of the body (body, waist, head, neck, buttocks, legs, etc.) ) To support the mattress and cushion, and the strength and resilience required for each part (where the body part comes into contact) is the thickness of the rubber (solid, upper and lower layers, sides) It can be easily adjusted by the thickness (volume) of the air layer. Thus, for example, a portable rubber mat equipped with this function can be rolled up and folded and carried around. When necessary, it can be used immediately after removing the lid and stopper (baby mat, sitting seat or neck support cushion). etc). As a nap mat for flooring, it is usually rolled up and stored compactly and can be used immediately after use. In this way, this rubber mat can be stored, carried, and carried according to the time and place of use, and can be easily expanded and used in a short time.

Embodiments of the present invention will be described below with reference to the drawings, taking as an example the form of a rubber mat that lays a baby.
Figure 1 shows the overall image when the rubber mat is unfolded. The surface shape is suitable for the baby's body, forming the concave 10a convex 10b, and has an appropriate flexibility. In order to maintain the flexibility of the rubber mat, flexible silicon rubber, synthetic rubber, raw rubber, synthetic resin, etc. are used. These materials are easily restored to their original shape even when rolled up and folded.

FIG. 2 shows a state where the rubber mat is folded and folded when stored. When you fold and fold using the flexibility of rubber, the air in the rubber mat is discharged from the inlet 11 and you can easily fold it. After the folding, the lid 12 is put on the injection port 11 and the band-like stopper 13 is used to keep the folded state.

Fig. 3 shows the rubber mat restored to its original shape as seen from the back. (State before closing and sealing the lid 12). When the stopper 13 and the lid 12 of the rubber mat in a rolled up and folded state are removed, the restoring force of the rubber mat itself and air flows from the installed inlet 11 to restore the original shape. The lid 12 is closed at the inlet 11 of the restored rubber mat, the air is sealed and the repulsive force is maintained, and the rubber mat functions.

FIG. 4 is a cross-sectional view showing a change pattern of the thickness of the rubber layer for adjusting the hardness of the rubber mat. Maximum hardness with solid rubber 14a (no hollow layer). 14b represents a state in which the upper and lower rubber layers have a uniform thickness and the thickness is changed at each location, and 14c represents a state in which the thicknesses of the upper and lower rubber layers facing each other are changed. The hardness can be adjusted by changing the thickness at each location. 14d represents the thickness of each side surface. Increasing the thickness of the side surface increases the hardness and repulsion. The difference in thickness of the rubber layer is adjusted between 0.1 mm and 200 mm.

FIG. 5 is a cross-sectional view showing a change pattern of the volume (height and width) of the air layer between the upper and lower rubber layers in order to adjust the repulsive force of the rubber mat. 15a represents a change in the thickness (volume) of the air layer. The repulsive force is obtained when the air layer is thick (height) and narrow (width), and the repulsive force is weaker as the air layer is thinner (height) and wider (width). The repulsive force required by these combinations can be adjusted. 15b shows a state in which the upper and lower rubber layers are in contact with each other because the load from above exceeds the resistance of the air layer. This is a means of fine adjustment of hardness and repulsive force.

The thickness of the rubber layer in FIG. 4 and FIG. 5 and the volume of the air layer between the rubber layers are the appropriate thickness and volume at the place where each part of the body is in contact in both the horizontal and vertical directions of the rubber mat. Can be set.
