Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air massage device for inflating and deflating an air bag to press and relax a treatment portion to massage by supplying and exhausting air by an air supply means.

[0002]

2. Description of the Related Art Conventionally, as an air massage device,
2. Description of the Related Art A chair-type air massager in which air bags are arranged in a seat portion and a backrest of a chair, a mat-type air massager in which air bags are arranged in a mat, and the like are known. These air massage devices expand and contract an air bag by supplying and exhausting air from an air supply means, and press the massaged part by the expanding and contracting air bag to perform massage.

As shown in FIGS. 9 to 11, an air bag 110 generally comprises two sheet members 111 and 11.
The outer peripheral portion of 2 is welded 113 to form a flat shape. A connection in which one end of the air bag 110, that is, the upper sheet member 111 in the drawing, is connected to the other end of an air hose 115 (shown by a chain double-dashed line) whose one end is connected to an air supply unit composed of an air compressor (not shown). The tool 100 is airtightly attached, and air is supplied to and exhausted from the air bag 110 via the connecting tool 100. The connecting tool 100 has an L-shaped connecting pipe 10 in which a connecting portion 102 for connecting an air hose 115 is formed at a tip portion thereof and a through hole 103 is formed therein.
1 and a disc-shaped flange portion 10 formed at the base of the connecting pipe 101 and having a through hole 103 opened 103a.
4 and. The connection tool 100 is attached by welding the surface of the flange portion 104 on the connection pipe 101 side to the upper sheet member 111 of the air bag 110.

As shown in FIGS. 9 to 11, the connecting tool 10 is used.
0 is the surface of the flange portion 104 on the side of the connecting pipe 101, that is, the attachment surface of the seat member 111 on the upper side of the airbag 110
It is airtightly attached to the inner surface of the unit by adhesion or the like. Further, the surface of the flange portion 104 opposite to the attachment surface, that is, the non-attachment surface is formed as a flat surface. Therefore, when the airbag 110 is in a contracted state, the flange portion 1
The non-attachment surface of 04 is in close contact with the inner surface of the seat member 112 below the airbag 110, and the opening 103 of the through hole 103
The sheet a is closed by the lower sheet member 112. The degree of this close contact is further increased by adding the weight of the user.

In this way, the flange portion 10 of the connector 100 is
When the non-attachment surface of No. 4 and the lower sheet member 112 are in close contact with each other, smooth inflow of air supplied from the air supply means into the air bag 110 is hindered. That is, the air flows into the through hole 103 and the opening 10
However, since the non-attachment surface of the flange portion 104 and the lower sheet member 112 are in close contact with each other at this time, air cannot flow into the air bag 110 smoothly. Therefore, the pressure of the air acts so as to separate the lower sheet member 112, which is in contact with the non-attachment surface of the flange portion 104, and the flow of air is started after the two are separated. Once the inflow of air is started, the inflow amount of air into the air bag 110 is accelerated and the air bag 110 is rapidly inflated.

As described above, when the non-attachment surface of the flange 104 and the lower sheet member 112 are in close contact with each other at the start of air supply, even if air supply to the air bag 110 is started. This air does not flow immediately, that is, at the same time as the start of air supply, into the air bag 110, and it takes time until a gap or flow passage is formed around the opening 103a of the flange 104 by the pressure of the air. It costs. That is, the start of inflow is delayed, and smooth inflow of air is hindered.

[0007]

As described above, in the prior art, the non-attachment surface of the flange portion 1104 of the connector 100 and the lower sheet member 112 of the air bag 110 are in close contact with each other. Even if the supply of air to the air bag 110 is started, this air cannot immediately flow into the air bag 110, and the air pressure causes the air to flow around the opening 103a of the flange 104. That is, since it takes time until the flow path is formed, there is a problem that smooth inflow of air cannot be performed.

If the opening 103a of the flange portion 104 of the connector 100 is closed by the other sheet member 112 as described above, the pressure in the through hole 103 becomes high immediately after the start of air supply. Therefore, each time the air is supplied when the air bag is inflated / deflated, the pressure of the air in the air supply path such as the air hose increases at the start of the air supply, so that it is necessary to increase the pressure resistance of the air supply path. Also, since the air supply means is overloaded each time air is supplied or exhausted, the capacity of the air supply means must be able to withstand this overload. In other words, since air must be supplied against the high pressure, the supply capacity of the air supply means must be increased, resulting in a large size and economical disadvantage.

[0009]

The present invention has been made in view of the above circumstances, and the invention according to claim 1 is an air bag that massages by expansion and contraction and is in a substantially flat state when contracted, and the air bag. The bag has an air supply means for supplying and exhausting air, a connecting pipe having a through hole, and a flange portion formed at the base of the connecting pipe and having the through hole opened, and the flange portion is attached to the air bag. In an air massager equipped with a connection tool that is attached to the air bag, the flange portion adheres to the inner surface of the air bag in an airtight manner, and an attachment surface opposite to the attachment surface. A non-attachment surface on the side, and a convex portion that forms an air inflow gap is formed in the vicinity of the opening of the through hole on the non-attachment surface of the flange portion exposed inside the airbag. That It is characterized.

According to the first aspect of the present invention, a convex portion is provided in the vicinity of the opening of the non-attachment surface of the flange portion of the connecting pipe opposite to the attachment surface of the air bag, so that the flange portion and the air bag are separated from each other. Since a gap for air to flow is formed between the inner surface,
When the air supply is started, the air can smoothly flow into the air bag.

Further, as described above, an air inflow gap is secured between the non-attachment surface of the flange portion and the inner surface of the air bag which faces the non-attachment surface to allow air to smoothly flow into the air bag. Therefore, it is possible to prevent the air supply means from being overloaded.

According to a second aspect of the present invention, in the first aspect of the invention, the connecting pipe has an L-shape having a connecting portion to which the base portion provided with the flange portion and the air hose are connected. In this connection pipe, the opening of the through hole is displaced from the central portion of the flange portion so that the outer peripheral edge portion of the flange portion is not located in the projection region of the connection pipe with respect to the flange portion. It is characterized by being provided.

According to the second aspect of the present invention, the amount of protrusion of the tip end of the connecting pipe from the air bag is reduced so that the connecting pipe can be prevented from hitting the user locally strongly and is connected to the connecting pipe. The air hose is arranged in parallel with the flange portion, so that the air hose can be prevented from bending even if the weight of the user is added.

[0014]

A joint portion 24 is provided on one side wall of the housing 20, and the joint portion 24 has a connecting portion 4 provided on one end side of the connecting hose group 3 composed of seven air hoses 3a. Are connected. A connecting portion 5 is similarly provided on the other end side of the connecting hose group 3, and the connecting portion 5 is connected to the connecting portion 14 (see FIG. 3) provided on the mat portion 1. Connection hose group 3 via this connection portion 14

g is communicated with and connected.

A power cord 25 is provided on the other side wall of the housing 20.
Is provided.

The construction of the air bags 11a to 11g will be described with reference to FIGS. Since the airbags 11a to 11g have the same configuration, only the airbag 11a will be described and the others will be omitted.

The air bag 11a is formed in a rectangular shape as shown in FIG. 1, FIG. 3 and FIG. As shown in FIGS. 5 to 7, the air bag 11a is formed in a bag shape by stacking two sheet members 31 and 32 and welding 33 at the outer peripheral edge portion by high frequency welding or the like. The air bag 11a is inflated by the supply of air, and is flat when the air is exhausted and contracted. A through hole 31a is formed in a central portion of the seat member 31, that is, a substantially central portion in a state where the airbag 11a is contracted into a flat state.

The connecting tool 40 attached to the sheet member 31 of the air bag 11a will be described. This connector 40
As shown in FIG. 6, an L-shaped connecting pipe 41 in which a through hole 43 is formed inside and a connecting portion 42 to which the air hose 12 a is connected is formed on the tip side, and the connecting pipe 41. It is composed of a disk-shaped flange portion 44 provided on the base portion. The through hole 43 of the connecting pipe 41 is opened in the flange portion 44 as indicated by reference numeral 45. The surface of the flange portion 44 on the connection pipe 41 side is an attachment surface 44a,
The surface opposite to the attachment surface 44a is a non-attachment surface 44b. The attachment surface 44a and the non-attachment surface 44b are formed as flat surfaces. Further, as shown in FIGS. 5 and 6, in the L-shaped connecting pipe 41, the opening 45 of the through hole 43 is displaced from the central portion of the flange portion 44, and the flange portion 44 is provided in the projection region with respect to the flange portion 44. Is provided so that the outer peripheral edge portion of is not positioned.

The base portion of the connecting pipe 41 is connected to the seat member 3
1 is inserted into the through-hole 31a formed in 1 and the attachment surface 4
By connecting 4a to the inner surface of the sheet member 31 by adhesion or the like, the connector 40 is airtightly attached to the sheet member 31, that is, the substantially central portion of the airbag 11a.

The non-attachment surface 44b of the flange portion 44 faces the inside of the air bag 11a.
A plurality of convex portions 44c are formed on the. This convex portion 44
As shown in FIG. 5, c is formed so as to be scattered around the opening 45, and is a region in the direction in which the connecting portion 42 projects, that is, a region projected onto the flange portion 44 of the connecting portion 42 and this region. In the peripheral area of the area, the center O of the opening 45
Are formed so as to be radially scattered about.

The convex portion 4 is formed on the non-attachment surface 44b of the flange portion 44.
Since 4c is formed, the non-attachment surface 4 of the flange portion 44 can be formed even if the airbag 11a is contracted into a flat state.
4b does not come into close contact with the sheet member 32, that is, a gap G having a height substantially equal to that of the convex portion 44c is formed. Therefore, the opening 45 is not closed in the hermetically closed state by the sheet member 32 even when the airbag 11a is contracted to be in a flat state. Since the gap G is formed on the peripheral edge of the opening 45, when the air supply is started by the air supply means (not shown), the air is supplied to the air bag through the gap G at the same time as the start of the supply. It can flow into the inside of 11a. Therefore, air does not have to go through the process of separating the flange portion and the sheet member, which are in close contact with each other at the start of the air supply, by the pressure of the air to form a gap as in the conventional case described above, and the air is blown into the air bag 1.
It can be fed or flowed into 1a. In this way, the air can smoothly flow into the air bag 11a.

In this case, the connecting tool 40 is attached to the air bag 11
The surface 44a attached to a is different from the surface 44b provided with the convex portion 44c for forming the inflow gap G described later.
In other words, the surface 4 for attaching to the air bag 11a
4a and the surface 44b on which the convex portion 44c for forming the inflow gap are provided are not separated from one surface of the flange portion 44 but are separated from each other.
Therefore, even if the size of the flange portion 44 is small, the adhesive area to the airbag 11a can be secured without being restricted by the convex portion 44c, and the convex portion 44c can be used as the adhesive area to the airbag 11a. It is possible to sufficiently exert the function of attaching to the air bag 11a and the function of providing the convex portion 44c forming the inflow gap, such as being able to be provided independently.

The connecting pipe 41 of the connecting tool 40 is formed in an L-shape, and the tip side of the connecting pipe 41, that is, the connecting portion 42 extends in one direction, that is, the longitudinal side surface of the airbag 11a. Therefore, the air bag 11 at the tip of the connecting pipe 41 is
The amount of protrusion from the side surface of a can be reduced, and the tip of the connecting pipe 41 is locally applied to the user during use, that is, when the user is lying on the mat portion 1 for massaging, as shown in FIG. Not hit strongly. In addition, the weight of the user is added to the connecting portion 42 during use, and therefore, a large force acts on the lower region on the connecting portion 42 side to bring the non-attachment surface 44b of the flange portion 44 into close contact with the sheet member 32. . However, as described above, in the region of the connecting portion 42 in the laterally protruding direction, the convex portions 44c are formed in a radial pattern with the center O of the opening 45 as the center. Therefore, the gap G is reliably formed between the non-attachment surface 44b and the sheet member 32.

Further, since the connecting portion 42 is parallel to the side surface of the airbag 11a, the air hose 12a connected to this connecting portion 42 can be bent even if the weight of the user is applied to the connecting portion 42. There is no. As a result, good air supply is achieved.

When manufacturing the airbag 11a, first, the connecting member 40 is inserted into the sheet member 31, the connecting pipe 41 is inserted into the through hole 31a as described above, and the attachment surface 44a is formed on the inner surface of the sheet member 31. It is attached by adhesion or the like. Then, the sheet member 31 and the sheet member 32 are overlapped,
Then, the outer peripheral portions of both sheet members 31 and 32 can be manufactured by welding 33 by high frequency welding.

In this case, the attachment surface 44a of the flange portion 44
The L-shaped connecting pipe 41 is less likely to interfere with the bonding of the air bag 11a and the sheet member 31 of the air bag 11a. That is, in order to attach the connector 40 to the air bag 11a, it is necessary to press the sheet member 31 of the air bag 11a adhered to the attachment surface 44a of the flange portion 44,
In this case, by pressing the outer peripheral edge of the flange portion 44 in an annular shape, airtightness can be maintained and bonding can be performed in an annular shape. In this way, since the portion separated from the L-shaped connecting pipe 41 can be pressed and adhered, the L-shaped connecting pipe 41 is less likely to get in the way.

In the air bags 11a to 11g produced as described above, the seat member 31 to which the connecting tool 41 is attached is opposite to the side on which the user lies down as shown in FIGS. In other words, it is arranged on the mat portion 1 so as to face downward. By thus locating the connector 40 on the side opposite to the side on which the user lies down, the connection tube 41 of the connector 40 is locally pressed against the user during massage.

The operation of the air massager will be described. First, the mat portion 1 and the air supply portion 2 are connected by the connection hose group 3.

The power switch 23 is closed, and then either the setting button 21a of the operation panel 21 or the setting button of a remote control device (not shown) is operated to set a desired massage mode. Then, after lying on the upper surface of the mat portion 1, the operation start button 21a of the operation panel 21
Alternatively, when the operation start button of the remote control device is operated, the control means drives the air supply means and executes the desired massage mode that has been set, and inflates the airbags 11a to 11g in the order determined by this massage mode. The distributor (not shown) is controlled so as to contract. Then, by the airbags 11a to 11g that expand and contract in this predetermined order, the pressure and relaxation of the treated portion of the human body is repeated to perform massage.

The non-attachment surface 44 of the flange portion 44 is also started at the time of starting the supply of air to the air bags 11a to 11g which are contracted and flattened during the massage.
This non-attachment surface 44b is formed by the convex portion 44c formed on b.
Since the gap G is formed between the sheet member 32 and the sheet member 32, the air smoothly flows into the inside of the air bags 11a to 11g through the gap G at the same time when the supply of air is started, and the air bags 11a to 11g quickly. Inflate to.

As described above, when the air massager is used to inflate and inflate the air bags 11a to 11g by supplying and exhausting air, when air supply is started, at the same time when the air supply is started, Splice 40
Non-attachment surface 44b of the flange portion 44 and the airbag 11
Air passes through the gap G formed between the sheet member 32 and the air bag 11a to 11g.
Pour into. As a result, the airbags 11a to 11g can be quickly inflated, and as a result, the treated portion can be pressed and relaxed in a regular expansion and contraction cycle, so that good massage can be performed.

As described above, the flange portion 44 of the connecting device 40.
Of the opening 4 by the convex portion 44c formed on the non-attachment surface 44b of
5 is a seat member 3 of the airbag 11a to 11g
It is not blocked by 2. Therefore, each time the air is supplied to the air bags 11a to 11g, the pressure of the air in the air supply path such as the air hoses 12a to 12g does not increase immediately after the start of the air supply. Therefore, it is not necessary to increase the pressure resistance of the air supply path, and it is not necessary to increase the supply capacity of the air supply means.

Further, since the convex portions 44c are arranged radially around the opening 45 of the flange portion 44 with the center point of the opening 45 as the center, the formation of the gap G can be ensured and the gap G can be ensured. The formation area of can be enlarged. As a result, the inflow of air is smoothly performed.

Since the connecting pipe 41 of the connecting tool 40 is formed in a substantially L-shape, the air bag 11a of the connecting tool 41 is formed.
1 to 11g, that is, the amount of protrusion from the mat portion 1 can be reduced, and the air hoses 12a to 12g can be arranged in parallel with the air bags 11a to 11g. Therefore, it is possible to prevent the air hoses 12a to 12g from being bent at the time of use and to prevent the flow passage cross-sectional area of the air hoses 2a to 12g from being reduced. Further, since the convex portions 44c are radially arranged in the region of the connecting pipe 41 in the projecting direction, the inflow gap G is surely provided in the region corresponding to the connecting pipe 41 in which the degree of adhesion between the flange portion 44 and the airbags 11a to 11g is increased. Can be formed. Therefore, the air can be smoothly introduced into the air bags 11a to 11g at the start of the air supply.

In the above embodiment, the connecting pipe 41 of the connecting tool 40 is formed in an L shape, but it is not always necessary to form the connecting tube 41 in an L shape, and the connecting pipe 41 should be made orthogonal to the attachment surface of the flange portion. You may form it.

Further, in the above embodiment, the convex portion 44c formed on the non-attachment surface 44b of the flange portion 44 of the connector 40 is formed as a projection, but this is not formed as shown in FIG. The convex portions may be formed by the ribs 144c formed radially. In this way, the convex portion is formed into the rib 144c.
In such a case, as shown in FIG. 8, it is desirable to form a large distance between the edge of some of the ribs 144c and the rim of the opening 45 so as to increase the gap opening around the opening 45.

When the flange portion 44 of the connector 40 is formed thick, the non-attachment surface 44 of the flange portion 44 is formed.
A plurality of radial grooves may be formed in b to form the gap G. When the grooves are formed in this way, both side walls forming the grooves correspond to the convex portions.

In the above embodiment, a plurality of convex portions 44c are formed around the opening 45, but the opening 45 of the non-attachment surface 44b of the flange portion 44 has the opening 45.
If there is a gap into which the air flows in without being blocked by the sheet members 32 of a to 11 g, the air flows in from this gap at an accelerated rate, so that the convex portion 44c becomes the non-attachment surface 44b. When a gap is formed between the sheet member 32 and the sheet member 32, the number may be one.

Further, in the above-mentioned embodiment, the case where the present invention is applied to the mat type air massager has been described, but this can also be applied to other types of air massager such as a chair type air massager. Is.

[0047]

According to the invention of claim 1 configured as described above, the opening of the through hole of the connector is formed on the non-attachment surface of the flange portion of the connector opposite to the attachment surface of the air bag. Since a convex portion was formed in the vicinity of, and the convex portion formed an inflow gap for air to flow between the flange portion and the inner surface of the airbag, the air can smoothly flow into the airbag at the start of air supply. In addition to the effect of being able to do so, the air can smoothly flow into the air bag in this way, so that it is possible to prevent the air supply means from being overloaded.

According to the second aspect of the present invention, the connecting pipe is L-shaped so that the amount of protrusion of the tip of the connecting pipe from the air bag is small, so that the connecting pipe does not hit the user locally strongly. At the same time, the air hose connected to the connecting pipe is arranged in parallel with the flange portion, and the bending of the air hose can be prevented.
