Abstract

PROBLEM TO BE SOLVED: To provide an air bed improved in comfortableness and adjustability. SOLUTION: An air bed includes three mutually independent airtight segments 28, 30, 32 fixed together in a straight line to form an air mattress 10 of a size suited for a bed of standard size. The segments of the air mattress can be mutually independently inflated, and a sleeper can adjust the level of support imparted to his head, waist, and legs, by varying air pressure within each segment. By arranging two air mattresses side by side, a bed of a large size suited for use by two sleepers is formed, and the air mattresses can be individually adjusted in the levels of support and comfortableness.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air bed, and more particularly, to an improved air bed having a plurality of parts which can be inflated independently of each other to provide various degrees of support to a sleeping body. Related to bed device.

[0002]

BACKGROUND OF THE INVENTION Air beds having a plurality of mutually inflatable mattresses for each sleeper are already known, but there is room for improvement. For example, air mattresses currently on the market suffer from bottoming if the weight placed on them is too high, and therefore lacks comfort.
Even in single mattresses and several pairs of mattresses that can be inflated independently of each other, a rolling effect occurs when a person lays down on the bed, causing the other person to rock. Furthermore, many conventional air mattresses are not always sufficient in terms of supporting a sleeper's body. Additional support is often required in the lower back due to the weight distribution of the sleeping person. In the case of conventional air mattresses, if the air pressure is increased to provide the required support for the waist, the comfort of the air mattress on the head and feet for a sleeper is reduced. If the waist cannot be adequately supported, the air mattress will be strongly compressed at the waist, but the weight at the head and feet will cause the sleeping person to sink into a valley. I will.

[0003]

SUMMARY OF THE INVENTION One object of the present invention is to provide an air bed device with improved comfort and adjustability.

[0004] It is another object of the present invention to provide an improved airbed apparatus that provides a mattress to each user individually.

It is yet another object of the present invention to provide an improved air bed apparatus wherein each mattress includes three or more airtight compartments.

Yet another object of the present invention is to allow the user to control the air pressure in each of the compartments comprising the mattress independently of one another, thereby providing individual support, comfort and adjustability. It is to provide an improved airbed device.

[0007] Briefly, the airbed apparatus of the present invention comprises three independent, airtight segments linearly secured to one another to form an air mattress sized for a standard twin bed. Contains. Each segment is inflatable independently of one another, and the sleeper can adjust the level of support by changing the air pressure within each segment. By arranging the two air mattresses of the present invention side by side, a full size, queen size, king size bed is formed for two sleepers, thereby providing each sleeper with a level of support and comfort. Can be adjusted individually.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows a standard air mat 10 formed of one airtight bag 12. Support is provided by air introduced into bladder 12 via a suitable valve 14 (preferably a double valve with a backflow preventive device). According to these valves (also known as Boston valves), it is known that the air mattress can be simply inflated and that air can be prevented from flowing out of the bag 12. The air mattress 10 further has a plurality of internal partitions 16 extending across its width. The partition 16 is connected to the upper member 18 and the lower member 2 of the bag 12 by a continuous welding seam 22.
It is fixed to 0. The partitions 16 define a plurality of chambers 24 connected therebetween, the structure of which substantially strengthens the air mattress 10 and improves support after inflation. The bag 12 shown in FIG. 1 fits a standard twin size bed and is sized to be used by a single sleeper. In general, it can be used by another sleeper and is substantially sized (length, height, width) to fit a standard large bed such as a full, queen, or king bed. An identical second air mattress is located adjacent to the first air mattress.

FIG. 2 shows the air mattress 26 of the present invention in a state where the segments constituting the air mattress 26 are linearly divided. A head segment 28 is disposed adjacent one end of the waist segment 30 and a foot segment 32
Are arranged on the side of the waist segment 30 opposite to the head segment 28. Each segment is preferably formed of high plasticizer content polyvinyl chloride with a laminate coating of a canvas-like rayon material, each segment forming an airtight compartment.
Suitable valves 34, 3 of the type described above for regulating the internal air pressure
6, 38 are provided for each segment. An additional layer of quilting material may be provided on the upper surface of the waist segment 30 to cover the upper surface.

Each segment has a number of double-walled internal partitions 40 extending across its width (see FIG. 3).
These partitions form compartments 42 connected to each other and provide additional support in inflating the mattress. As can be seen in FIG. 3, each partition 40 is hollow, has holes 44 at both ends and has holes 46 in the center, these holes move from one compartment to another as weight acts on the segment. Allow air to flow. Each partition 40 is preferably welded at its upper surface 48 and lower surface 50 to the corresponding upper and lower members of the segments (28, 30, 32). The weld seam extends horizontally, approximately 1/2 inch at each partition 40
(13 mm). This partition structure provides a large seam surface and two partition walls (52 and 54) to increase air capacity and strength. The number of partitions 40 in each segment depends on the required size and strength of the air mattress 26.

As shown in FIG. 4, the assembled air mattress 26 has a head segment 28 fixed to one side of the waist segment 30 and a head segment of the waist segment 30. It is formed by fixing the foot segment 32 on the side opposite to the side 28. A preferred method for securing each segment to one another is a fastener strip 56A comprising cooperating hooks and loops disposed along the upper edge 57 and lower edge 58 of each segment as shown in FIG.
And 56B (for example, sold under the trade name Velcro).

The assembled air mattress 26 is preferably placed on a foundation 60 (see FIG. 5) that includes a peripheral rail 62 made of foam material and is covered with a vinyl fabric material. The valves 34, 36, 38 are then connected to two or more pneumatic pumps 64, 66 housed in the foundation 60 to reduce the level of operating noise. The control device 68 controls the pneumatic pumps 64, 66 individually, so that the person using the air mattress 26 can use the head segment 28,
The waist segment 30 or the foot segment 32 can be individually inflated or deflated, and both the head and foot segments can be adjusted simultaneously, independently of the waist segment.

When the above-described air bed device is applied to a large bed such as a full size, queen size or king size bed, a second air mattress is used (see FIG. 6). The second air mattress is a mirror image of the first air mattress and has a second set of identical pneumatic pumps and independent controls located within the foundation 60. By providing a second set of pneumatic pumps and controls, each sleeper adjusts the second portion of the air bed apparatus without adversely affecting the comfort of the other sleeper lying on the first air mattress. You can adjust your level of comfort individually.

In the above, the present invention has been described in detail with respect to a specific embodiment. However, the present invention is not limited to the above embodiment, and various other embodiments are included in the scope of the present invention. It will be clear to those skilled in the art that is possible.
