Description

[Technical field]

[0001] SUMMARY OF THE DISCLOSURE The present invention relates to an air mattress. [Background technology]

[0002] There is known an air mattress that includes multiple air cells. For example, in this type of air mattress, multiple snap buttons are attached to the side of the cover by crimping, and are integrated by fitting with the buttons provided on the air cells. In addition, to prevent the air cells from falling over, two buttons are provided on both sides and in the upper and lower directions on the air cells.

[0003] In addition, some air mattresses do not have buttons, for example, in order to simplify the structure of the cover. In this type of air mattress, in order to prevent the air cells from collapsing, multiple air cells are linked together to form an integrated air cell unit, which is then lined up in multiple units.

[0004] [Patent Document 1] JP 2017-124012 A Summary of the Invention [Problem to be solved by the invention]

[0005] The air mattress as described above is used, for example, by being placed on an electric bed. In this case, in the case of an air mattress in which the snap buttons on the side of the cover and the buttons of the air cells are connected, when the back bottom of the electric bed rises, the cover portion between the buttons of the air cells included in the bending part of the air mattress becomes taut. This hinders the flexibility of the air mattress. In addition, the material of the cover needs to have a strong fabric and structure in order to connect the buttons of the air cells, which makes the cover structure complicated and expensive. Furthermore, when performing maintenance work on the cover, it is more troublesome to remove the air cells from the cover.

[0006] Here, it is also possible to attach the upper and lower buttons of the air cell to the belt instead of the cover. This configuration simplifies the structure of the cover, reduces the cost, and reduces the labor required. On the other hand, because the upper and lower belts slide, the air cell may collapse, and the air mattress's function of achieving the desired softness or hardness cannot be achieved.

[0007] Air mattresses that use air cell units do not impede the flexibility of the air mattress and can prevent the air cells from collapsing. However, when one of the air cells is damaged and needs to be replaced, it can only be replaced as an air cell unit. Furthermore, the manufacturing equipment for producing air cell units is larger than that for producing air cells, and is therefore more expensive.

[0008] An embodiment of the present invention provides an air mattress in which multiple air cells are connected in a simple configuration. [Means for solving the problem]

[0009] According to an embodiment of the present invention, an air mattress includes a first air cell and a second air cell, each of which has a cylindrical flexible tube and a blocking portion that blocks both ends of the flexible tube, the blocking portion including a first button and a second button. The air mattress further includes a connecting member that connects the first button of the first air cell to the second button of the second air cell, and a connecting member that connects the second button of the first air cell to the first button of the second air cell.

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between parts, etc. are not necessarily the same as those in reality. Even when the same part is shown, the dimensions and ratios of each part may be different depending on the drawing. In this specification and each drawing, elements similar to those described above with reference to the previous drawings are given the same reference numerals and detailed descriptions thereof will be omitted as appropriate.

[0013] (First embodiment) FIG. 1 is a perspective view showing an example of the appearance of an air cell 10. As shown in FIG. As shown in FIG. 1, the air cell 10 includes a cylindrical flexible tube 11 and blocking portions 12 that block two ends of the flexible tube 11. In the following description, the longitudinal direction of the flexible tube 11 may be defined as the X-axis direction, the width direction of the flexible tube 11 as the Y-axis direction, and the height direction of the flexible tube 11 as the Z-axis direction. In the YZ plane, the flexible tube 11 has, for example, an elliptical or rectangular shape that is long in the Z-axis direction, and has a predetermined length in the X-axis direction. In this embodiment, the shape of the flexible tube 11 in the YZ plane is, for example, a shape in which two circular members are joined together, as shown in FIG. 3 described later. Although not shown, the air cell 10 is provided with an intake and exhaust port that intakes and exhausts gas (for example, air) in the air cell 10.

[0014] The blocking portion 12 is provided with an ear portion 13 at the center in the Y-axis direction and along the Z-axis direction. A first button B1 is provided at one end of the ear portion 13 in the Z-axis direction, and a second button B2 is provided at the other end. The first button B1 and the second button B2 are attached, for example, by crimping the buttons.

[0015] At the lower end of the side surface of the flexible cylinder 11, three connecting parts 14a, 14b, and 14c are provided. Among the three connecting parts 14a, 14b, and 14c, 14b is provided at the central part, 14a is provided at the end on the back side in the X-axis direction, and 14c is provided at the front side end. Although not shown in the figure, the three connecting parts are provided at the same positions on the opposite side surface of the flexible cylinder 11. The connecting parts 14a, 14b, and 14c on one surface are each convex (so-called male), and the three connecting parts on the other surface are each formed in a concave shape (so-called female). For this reason, the connecting parts 14a, 14b, and 14c of the air cell 10 and the three connecting parts of the adjacent air cell 10 can be respectively fitted. In the present embodiment, the case where three sets of connecting parts are provided on one flexible cylinder 11 will be described, but it is not limited to this. For example, one set may be provided at the central part of the flexible cylinder 11. When the connecting parts 14a, 14c, and 14c are connected, there is a slight margin between the adjacent air cells 10 in the Y-axis direction. For this reason, even when the adjacent air cells 10 are connected by the connecting parts 14a, 14c, and 14c, it is possible to widen the lower distance between the air cells 10.

[0016] Figure 2 is a diagram showing an example of the air mattress 20 and the operation unit 30. As shown in FIG. 2, the air mattress 20 includes a plurality of air cells 10, a pump unit 21, and a cover 22. The plurality of air cells 10 are housed in the air mattress 20. The plurality of air cells 10 are arranged adjacent to each other such that the longitudinal direction is along the Z-axis direction in the YZ plane and the longitudinal direction is along the X-axis direction in the XY plane. The plurality of air cells 10 arranged in the air mattress 20 are connected. Details of the connection structure of the plurality of air cells 10 will be described later.

[0017] Gas is accommodated inside each air cell 10. The pump unit 21 is connected to each of the air cells 10. The pump unit 21 supplies gas to the air cells 10 through an intake and exhaust port (not shown). Alternatively, the pump unit 21 exhausts gas from inside the air cells 10 through the intake and exhaust port (not shown). The cover 22 covers the air cells 10 and the pump unit 21.

[0018] The pump unit 21 is located, for example, on the foot side of a person sleeping on the air mattress 20. The head side and the foot side of the air mattress 20 are determined, for example, from letters or pictures attached to the air mattress 20.

[0019] The operating unit 30 can operate the control of the air mattress 20 (pump unit 21). For example, a user (a person sleeping on the air mattress 20) can use the operating unit 30 to increase or decrease the pressure inside the air cell 10. This makes it possible to make the air mattress 20 harder or softer. The operating unit 30 is electrically connected to the pump unit 21 by a cable 31, for example, as shown in FIG. 2. The operating unit 30 may be connected to the pump unit 21 so as to be able to communicate with it by wireless communication means.

[0020] The air mattress 20 is included in, for example, an electric bed, which will be described later.

[0021] Next, a connection structure 100 for multiple air cells 10 stored in the air mattress 20 will be described. Fig. 3 is a side view showing an example of a connection structure for three adjacently arranged air cells 10a, 10b, and 10c. Note that the side opposite to the side shown in Fig. 3 has a similar connection structure, so illustration and description thereof will be omitted.

[0022] 3, the air cell 10a, the air cell 10b, and the air cell 10c are arranged adjacent to each other. Each of the air cells 10a, 10b, and 10c is arranged such that the first button B1 of the ear portion 13 is on the upper side and the second button B2 is on the lower side in the Z-axis direction. The air mattress 20 includes a connecting member 41 that connects the first button B1 of the air cell 10a, the second button B2 of the air cell 10b, and the first button B1 of the air cell 10c, and a connecting member 42 that connects the second button B2 of the air cell 10a, the first button B1 of the air cell 10b, and the second button B2 of the air cell 10c.

[0023] 3, as shown by dashed lines, a connecting member 41 is connected to the second button B2 of the air cell 10 arranged adjacent to the left side of the air cell 10a, and a connecting member 42 is connected to the first button B1. Also, as shown by dashed lines, a connecting member 42 is connected to the first button B1 of the air cell 10 arranged adjacent to the right side of the air cell 10c, and a connecting member 41 is connected to the second button B2. In this manner, all of the air cells 10 included in the air mattress 20 are connected by the connecting members 41 and 42. The distance between adjacent first buttons B1 and the distance between adjacent second buttons B2 are each defined as width W1.

[0024] The connecting members 41, 42 are, for example, belt-shaped, and have snap buttons attached by crimping at a predetermined interval. The first button B1 or the second button B2 is fitted into each of the snap buttons. In this manner, the air cells 10a, 10b, 10c and the connecting members 41, 42 are fitted together, respectively. Furthermore, in this embodiment, the three connecting portions 14a, 14b, 14c of the adjacent air cells 10 are connected to each other.

[0025] Next, the operation of the air cell 10 connected as described above will be described. Fig. 4 is a diagram showing an example of an electric bed 40 including an air mattress 20. Fig. 4(a) shows the air mattress 20 in a horizontal state. Fig. 4(b) shows the air mattress 20 in a bent state with the back bottom 40a raised.

[0026] As shown in Fig. 4(a), the electric bed 40 includes a back bottom 40a, a waist bottom 40b, a knee bottom 40c, and a foot bottom 40d, and the air mattress 20 is placed on the back bottom 40a, the waist bottom 40b, the knee bottom 40c, and the foot bottom 40d. The back bottom 40a supports the head and back of a person sleeping on the air mattress 20, the waist bottom 40b supports the waist area, the knee bottom 40c supports the knee area, and the foot bottom 40d supports the foot area. The back bottom 40a can be operated to rise from a horizontal state to a predetermined angle by the user's operation of the operating unit 30, for example, to raise the upper body of the person sleeping on the air mattress 20.

[0027] In the state shown in Fig. 4(b), a bending portion P where the air mattress 20 bends is formed in a portion located above the joint between the back bottom 40a and the lumbar bottom 40b. Since the back bottom 40a and the air mattress 20 operate integrally, the bending rate of the bending portion P of the air mattress 20 increases as the back bottom 40a rises.

[0028] Fig. 5 is a diagram showing an example of the state of a plurality of air cells 10 included in a bent portion P formed in an air mattress 20. Note that Fig. 5 mainly illustrates connecting members 41 and 42 that connect air cells 10a, 10b, and 10c.

[0029] 5, the air mattress 20 bends, so that the spacing between the air cells 10a, 10b, and 10c on the back bottom 40a side moves in the direction in which the width of the connecting member 41 increases, as shown by the double arrow in the figure. At this time, the spacing of the connecting member 41 that connects the second button B2 of the air cell 10a and the second button B2 of the air cell 10c increases around the first button B1 of the air cell 10b, and the spacing between the second button B2 of the air cell 10a and the second button B2 of the air cell 10b, and the spacing between the second button B2 of the air cell 10b and the second button B2 of the air cell 10c each become width W2 (>width W1).

[0030] In addition, the spacing between the air cells 10a, 10b, 10c on the upper side of the back bottom 40a changes as the air mattress 20 bends, as shown by the arrow in the figure, in the direction in which the width of the connecting member 42 narrows around the second button B2 of the air cell 10b. At this time, the spacing between the first button B1 of the air cell 10a and the first button B1 of the air cell 10b, and the spacing between the first button B1 of the air cell 10b and the first button B1 of the air cell 10c each become width W3 (<width W1).

[0031] In this way, the lower sides of the air cells 10a, 10b, 10c can be expanded without being stretched, and the upper sides can be narrowed, so that the air mattress 20 can bend smoothly in response to the upward movement of the back bottom 40a.

[0032] As described above, the air mattress 20 includes a connecting member 41 that connects a plurality of air cells 10, for example, the first button B1 of the air cell 10a, the second button B2 of the air cell 10b, and the first button B1 of the air cell 10c, and a connecting member 42 that connects a plurality of air cells, for example, the second button B2 of the air cell 10a, the first button B1 of the air cell 10b, and the second button B2 of the air cell 10c. In this manner, the plurality of air cells 10 included in the air mattress 20 are connected alternately in the vertical direction by the connecting members 41 and 42. Therefore, the air mattress 20 in which a plurality of air cells 10 are connected can be provided with a simple configuration.

[0033] In addition, in the electric bed 40 including the air mattress 20, in the bent portion P formed when the back bottom 40a rises, the width W2 between the adjacent second buttons B2 of the air cells 10a, 10b, 10c arranged in the bent portion P becomes wider than the width W1 when the back bottom 40a is in a horizontal state. On the other hand, the width W3 between the first buttons B1 becomes narrower than the width W1. Therefore, when the back bottom 40a rises, the lower surface side of the air mattress 20 is not stretched, and the upper side can be narrowed. Therefore, the electric bed 40 can be made with improved flexibility of the air mattress 20.

[0034] Furthermore, the first button B1 and the second button B2 of the air mattress 20 are exposed, and the snap buttons provided on the connecting members 41, 42 can also be easily seen by an operator. In addition, the connecting members 41, 42 are belt-shaped and smaller in size than the cover 22. For this reason, when connecting the air cell 10 and when dismantling the air mattress 20 during maintenance work, it is easier for an operator to connect and dismantle the air cell 10 compared to attaching or detaching the air cell 10 to or from the cover 22.

[0035] Furthermore, in the air mattress 20, the connecting members 41, 42 are attached to the first button B1 and the second button B2 alternately on the sides of the plurality of air cells 10. This enhances the integrity of the plurality of air cells 10 and prevents the air cells 10 from collapsing. In other words, it is possible to prevent the air cells 10 from collapsing and becoming unable to perform their function of hardening or softening.

[0036] Furthermore, when one air cell 10 of the air mattress 20 is broken, the first button B1 and the second button B2 of the broken air cell 10 can be easily replaced with a new air cell 10 by removing the first button B1 and the second button B2 of the broken air cell 10 from the connecting members 41 and 42. On the other hand, in the case of an air cell unit in which a plurality of air cells 10 are connected, replacement is performed on an air cell unit basis. Therefore, the air mattress 20 of this embodiment can keep the running cost low. When manufacturing an air cell unit, the manufacturing equipment becomes large, the manufacturing takes a long time, and there is inconvenience in transportation and storage compared to the case of manufacturing a single air cell 10, which leads to high prices. On the other hand, the air mattress 20 of this embodiment can be manufactured on an air cell basis, so that the manufacturing equipment can be made small, the manufacturing time can be shortened, and transportation and storage can be facilitated, resulting in low prices.

[0037] Furthermore, the air mattress 20 is configured to connect three connection portions of adjacent air cells 10. This can further improve the integrity of the multiple air cells 10.

[0038] Other embodiments of the connection structure of the plurality of air cells 10 will be described below.

[0039] Second embodiment FIG. 6 is a side view showing an example of a connection structure 101 of the air cell 10 of the second embodiment. 6, in the connecting structure 101, the first button B1 and the second button B2 of each air cell 10 are connected vertically by connecting members 43 and 44 alternately, and adjacent connecting members 43, 44 are connected so as to cross. Note that the connecting members 43, 44 may be members of the same shape. With a structure connecting a plurality of air cells 10 in this way, it is possible to achieve the same effects as the above embodiment.

[0040] Third embodiment FIG. 7 is a side view showing an example of a connection structure 102 of the air cell 10 of the third embodiment. 7, in the connecting structure 102, the first buttons B1 of adjacent air cells 10 are connected to each other by connecting member 45, and the second buttons B2 of adjacent air cells 10 are connected to each other by connecting member 46, and the connecting members 45, 46 arranged above and below are connected so as to cross. Note that the connecting members 45, 46 are each connected by a single belt, but adjacent air cells 10 may be connected to each other by using a plurality of connecting members that connect adjacent air cells 10. Even with a structure that connects a plurality of air cells 10 in this manner, it is possible to achieve the same effect as the above embodiment.

[0041] (Fourth embodiment) FIG. 8 is a side view showing an example of a connection structure 103 of the air cell 10 of the fourth embodiment. As shown in FIG. 8, in the connection structure 103, the first buttons B1 of adjacent air cells 10 are connected by a connection member 47. The connection member 47 is belt-shaped. The connection members 47 are provided in a straight line in a side view so as to connect the first buttons B1 of the air cells 10. In addition, the first button B1 of an air cell 10, the second button B2 of an air cell 10 adjacent to this air cell 10, the first button B1 of an air cell 10 adjacent to this air cell 10, ... are alternately connected by a connection member 48. The connection member 48 is belt-shaped. Even with a structure that connects a plurality of air cells 10 in this manner, it is possible to achieve the same effects as the above embodiment. To explain an example of the effect in detail, the upper surface side of the air mattress 20 prevents the air cells 10 from falling over by the connecting members 47, and when the back bottom 40a provided on the electric bed 40 rises, the lower surface side of the air mattress 20 widens the distance between the second buttons B2 by the connecting members 48, so that the air mattress 20 is prevented from being stretched when the back bottom 40a rises, and can bend smoothly following the movement of the back bottom 40a. Note that each of the connecting members 47, 48 does not have to be composed of a single belt, and for example, a plurality of air cells 10 may be connected using a plurality of belts that connect adjacent air cells 10.

[0042] Fifth embodiment FIG. 9 is a side view showing an example of a connection structure 104 of the air cell 10 of the fifth embodiment. 9, the connecting member 49 has an X-shape. A snap button is attached to each of the four ends of the connecting member 49 by crimping (not shown). In the connecting structure 104, the four snap buttons of the connecting member 49 are connected to four buttons, namely, the first button B1 and the second button B2 of the air cell 10, and the first button B1 and the second button B2 of the adjacent air cell 10. Even with a structure that connects a plurality of air cells 10 in this way, it is possible to achieve the same effects as the above embodiment.

[0043] Sixth embodiment FIG. 10 is a side view showing an example of a connection structure 105 of the air cell 10 of the sixth embodiment. As shown in FIG. 10, in the connection structure 105, the first button B1 of the air cell 10 and the second button B2 of the adjacent air cell 10 are connected by a connection member 50, and the second button B2 of the air cell 10 and the first button B1 of the adjacent air cell 10 are connected by a connection member 51. This connection structure is similar to that of the fifth embodiment. The difference from the fifth embodiment is that the first button B1 of the air cell 10 and the second button B2 of the adjacent air cell 10 are connected by a belt-shaped connection member 50, not an X-shape like the connection member 49, and the second button B2 of the air cell 10 and the first button B1 of the adjacent air cell 10 are connected by a belt-shaped connection member 51. That is, the connection structure 105 is connected by the individual connection members 50 and 51. Even with a structure that connects a plurality of air cells 10 in this way, it is possible to achieve the same effects as the above embodiment.

[0044] Seventh embodiment The seventh embodiment is a connecting structure that is flexible so as to prevent tension only in the multiple air cells 10 located at the joint between the back bottom 40a and the lumbar bottom 40b in an electric bed 40 including an air mattress 20, for example.

[0045] FIG. 11 is a side view showing an example of a connection structure 106 of the air cell 10 of the seventh embodiment. 11, when the air cell 10d and the air cell 10e adjacent to the air cell 10d are located on the joint between the back bottom 40a and the waist bottom 40b, the connecting structure 106 connects the first button B1 of the air cell 10d and the second button B2 of the air cell 10e with the connecting member 52, and connects the second button B2 of the air cell 10d and the first button B1 of the air cell 10e with the connecting member 53. In the portions other than the portions connected in this way, the connecting members 52 and 53 are connected to the first button B1 and the second button B2 in a straight line in a side view. Even with a structure connecting a plurality of air cells 10 in this way, it is possible to achieve the same effect as the above embodiment. To explain one example of the effect in detail, by connecting multiple air cells 10d, 10e in this way, it is possible to provide pinpoint flexibility, that is, the width of the interval between the second buttons B2 can be increased, and tension can be prevented at the points where the connecting members 52, 53 intersect, improving the flexibility of the air mattress 20. Also, since multiple air cells 10 are connected including the parts where the connecting members 52, 53 intersect, it is possible to prevent the entire air cell 10 from sliding and collapsing.

[0046] In each of the above embodiments, the air mattress 20 is applied to an electric bed, but the air mattress 20 can be used for other purposes besides an electric bed. For example, the air mattress 20 can be used in a chair installed in a mobile device (e.g., passenger aircraft, electric vehicles, etc.) for long-distance travel.

[0047] The above describes the embodiment of the present invention with reference to specific examples. However, the present invention is not limited to these specific examples. For example, the specific configurations of each element, such as snap buttons, buttons, movable parts, and bottoms, included in an air mattress and an electric bed are included in the scope of the present invention as long as a person skilled in the art can implement the present invention in a similar manner and obtain similar effects by appropriately selecting from the known range.
