Description

Technical Field

[0001] This invention relates to an inflatable mat, when used as a mat, in which an air layer is blown into a sealed space formed by two layers of airtight fabric and the adhesive line between the fabrics to support the user's weight, thereby providing heat insulation and cushioning between the user and the ground. When not in use, the air can be extracted to reduce the volume and make it easy to fold and handle, as well as a method for manufacturing the same. Background Technology

[0002] Generally, an air mattress is formed by sealing airtight fabric in a four-cornered shape with a predetermined height, and is equipped with one or more valves for injecting and expelling air. Therefore, it is easy to carry and move. It can be used not only for leisure activities such as mountain climbing and travel, but also as a medical device to prevent bedsores. Furthermore, the air mattress does not simply have an air layer inside, but also has vertical reinforcing bands connecting the upper and lower parts, or densely formed with vertically running fiber filaments. Therefore, it can prevent twisting and slipping during use and can easily come into contact with the curved body.

[0003] However, if the conventional inflatable mat has internal reinforcement strips, these strips may fall off and are difficult to repair. If they are placed inside, they reduce the cushioning effect. Furthermore, if there are many fibers, they will clump together, reducing the flatness of the inflatable mat. Some fibers may break, and if the fibers break continuously, the airtightness will be reduced.

[0004] The background technology of this invention is documented in Korean Utility Model Publication No. 20-0388951, which was applied for and granted on June 28, 2005. Summary of the Invention

[0005] The problem that the invention aims to solve

[0006] The purpose of this invention is to provide an inflatable mat and its manufacturing method that improve upon the following problems in conventional inflatable mats: In conventional inflatable mats, the portion that collapses excessively when bearing the user's weight fails to adequately provide insulation and cushioning between the user and the ground; the large height difference between the weight-bearing portion and the unweight-bearing portion that expands due to the balloon effect, along with the wide contact (friction) area between the user and the inflatable mat, makes it difficult for the user to move on the inflatable mat; the need to blow air in or to equip it with an additional air pump; the inability to continuously inject or deflate air using an air pump; the danger of the inflatable mat being too high, causing the user to lose balance and fall; and the difficulty in dehydrating the inflatable mat during washing due to its airtight fabric construction.

[0007] means for solving problems

[0008] This invention provides an inflatable mat and its manufacturing method with the following features: it comprises multiple air bags 210 that allow air to flow between each other and also block airflow. The air bags 210 support the user's weight with the airflow blocked, thereby improving the problem of excessive collapse of the weight-bearing portion in conventional inflatable mats. This provides insulation and cushioning between the user and the ground, and reduces the height difference between the weight-bearing collapsed portion and the unweight-bearing portion inflated by the balloon effect, as well as the contact (friction) area between the user and the inflatable mat. Therefore, the user can easily move or turn over on the inflatable mat. Furthermore, a portion of the inflatable mat itself functions as an air pump 230, 240, 330, and 340, thus eliminating the need for... Air needs to be blown in by mouth or an additional air pump is provided. Two bag system air intake pumps 230, two hose system air intake pumps 330, one bag system air exhaust pump 240, and one hose system air exhaust pump 340 are each formed as a group. Therefore, air can be continuously injected and discharged by alternately applying pressure. Furthermore, a hot-press weld point 500 is formed on the plane of the air bag 210, which is a pad component 100 that is squeezed at one point or several points at predetermined intervals and is hot-press welded. This makes the height of the air-filled inflatable pad appropriate, thereby reducing the risk of people losing their balance and falling. Furthermore, holes or gaps 600 that facilitate drainage are formed at the hot-press weld point 500, so that the inflatable pad made of airtight fabric can be smoothly dehydrated when washing.

[0009] Invention Effects

[0010] The inflatable mat of this invention solves the problem of excessive collapse of the weight-bearing part in conventional inflatable mats, and provides heat insulation and cushioning between the user and the ground. It also reduces the height difference between the weight-bearing collapsed part and the unweight-bearing part that is inflated due to the balloon effect, as well as the contact (friction) area between the user and the inflatable mat. As a result, the user can easily move and turn over on the inflatable mat. Furthermore, it can continuously inject or expel air without the need to blow air in with one's mouth or use an additional air pump. It also reduces the risk of people losing balance and falling when stepping on an air-filled inflatable mat. It also allows for smooth dehydration during washing. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 3 As shown in the figure, the inflatable cushion according to an embodiment of the present invention is formed by the following structure: a bag system air intake / exhaust port 201, a hose system air intake / exhaust port 301, and a hose component 310 are arranged as shown in the figure between the lower plate 110 and the upper plate 120, and then hot-press welded with a hot-press weld line 400 after compression; with the hose component 310 as the boundary, and the bag system air intake / exhaust port 201, the air bag 210, and the connecting portion 220 between the air bags as constituent elements, a structure that supports the user's weight is formed by... Figure 4 The air system shown (referred to as bag system 200) consists of an air intake / exhaust port 301, a hose component 310, and a connecting portion 320, and functions to block the airflow between air bags 210. Figure 5 The air system shown is for airflow (referred to as hose system 300).

[0023] First, when injecting air into the bag system 200, such as Figure 6 As shown, the air passage 225 formed by thermoforming is intentionally skipped at the connection 220 between the air bags, and the gap between the pad component 100 and the hose component 310. This allows airflow between the air bags 210, filling the entire bag system 200 with air. Then, when air is injected into the hose system 300 at a higher pressure than that of the bag system 200, the hose component 310 expands, blocking the gap between the air passage 225 formed by thermoforming the connection 220 between the air bags, and the gap between the pad component 100 and the hose component 310. This is similar to... Figure 7 As shown, the airbags 210, which block the airflow between each other, can support the user's weight, thereby alleviating the excessive collapse of the weight-bearing part that occurs in conventional inflatable mats. This provides heat insulation and cushioning between the user and the ground, and reduces the height difference between the weight-bearing collapsed part and the unweight-bearing part that inflates through the balloon effect, as well as the contact (friction) area between the user and the inflatable mat. Therefore, it is easy for the user to move or turn over on the inflatable mat.

[0024] like Figure 9 As shown, elastomers 234, 244, 334, and 344 are filled into specific spaces formed by the hot-pressed weld lines 400 between the pad components 100. Air inlets 232, 242, 332, and 342, and exhaust ports 233, 243, 333, and 343, which are check valves that allow air flow in only one direction through the hot-pressed weld lines 400 forming the corresponding spaces, are configured. When pressure is applied to the elastomers 234, 244, 334, and 344, the elastomers 234, 244, 334, and 344 expel the contained air to the exhaust ports 233, 243, 333, and 343. When the pressure is released from the elastomers 234, 244, 334, and 344, air is drawn in through the air inlets 232, 242, 332, and 342 by means of a restoring force. This process is repeated, thus... Figure 8 As shown, because it has air pumps 230, 240, 330, and 340 that act as pumps, the inflatable pad does not require blowing air in with your mouth or using a separate air pump.

[0025] like Figure 8 As shown, two bag system air intake pumps 230, two hose system air intake pumps 330, one bag system air exhaust pump 240 and one hose system air exhaust pump 340 form a group, thus, by alternately applying pressure, air can be continuously injected and discharged.

[0026] like Figure 8As shown, a pad component 100 with one or several compression points at predetermined intervals is formed on the plane of the air bag 210 and a hot-press weld point 500 is formed by hot-press welding. This makes the height of the air-filled inflatable pad suitable, thereby reducing the risk of people losing their balance and falling when stepping on the air-filled inflatable pad.

[0027] like Figure 8 As shown, a hole or gap 600 is formed in the hot-pressed weld point 500 to facilitate drainage of the through-pad component 100, so that the air pad made of airtight synthetic resin fabric can be smoothly dehydrated when washed.

[0028] like Figure 10 As shown, the method for manufacturing an inflatable pad according to the present invention comprises the following steps: step S10 of laying out the lower plate 110; step S20 of arranging and fixing the air intake / exhaust ports 201, 301 or air pump inlets 232, 242, 332, 342, exhaust ports 233, 243, 333, 343, elastomers 234, 244, 334, 344 and hose components 310; step S30 of overlapping the upper plate 120; step S40 of hot-press welding the compressed pad components 100; and step S50 of creating gaps in the pad components 100 and holes or slits 6 for drainage during washing of the inflatable pad. Step S50: Cutting; Step S60: Covering or clamping the caps or clips 700 that block the air intake / exhaust ports 201, 301 or the air intake pump inlets 232, 332 and the air exhaust pump outlets 243, 343; Step S70: Filling both air systems of the completed inflatable pad with air and immersing it in liquid to check for air bubbles to confirm airtightness; Step S80: Expelling air from one air system of the completed inflatable pad and injecting air into only the other air system, and checking whether the air-expelled air system inflates, thereby confirming the airtightness between the two air systems.

Claims

1. An inflatable mat, which, when used as a mat, allows air blown into a sealed space formed by two layers of airtight fabric and the adhesive lines between the fabrics to support the user's weight, thereby providing insulation and cushioning between the user and the ground; and, when not in use, allows air to be released, reducing its volume and making it easy to fold, is characterized in that... The inflatable pad is formed by arranging bag system air intake / exhaust ports (201), hose system air intake / exhaust ports (301) and hose components (310) between the lower plate (110) and the upper plate (120) and then hot-press welding lines (400) are formed by compression. A bag system (200) that supports the user's weight, with the hose component (310) as the boundary and the bag system air intake / exhaust port (201), air bag (210) and the connection part (220) between the air bag (210) as the constituent elements. A hose system (300) consisting of a hose system intake / exhaust port (301), a hose component (310), and a connecting part (320) has the function of blocking the airflow between air bags (210). First, when air is injected into the bag system (200), airflow is generated between the air bags (210) through the air circulation hole (225) and the gap between the pad component (100) and the hose component (310), so that the entire bag system (200) is filled with air. Then, when air is injected into the hose system (300) at a higher pressure than that of the bag system (200), the hose component (310) expands and blocks the gap between the air circulation hole (225) and the pad component (100) and the hose component (310), so that the airflow between them is blocked. The air bags (210) in this state can support the user's weight, thereby alleviating the phenomenon of excessive collapse of the weight-bearing part. This provides heat insulation and cushioning between the user and the ground, and reduces the height difference between the weight-bearing collapsed part and the unweight-bearing part that is inflated by the balloon effect and the contact friction area between the user and the inflatable mat.
