Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventionally sold deformable cushions such as body pillows are comfortable cushions because they naturally deform into a shape that conforms to the user's body. However, in recent years, there has been a demand for further improvement in the relaxation effect in deformable cushions. In order to meet such user needs, in addition to the conventional function of naturally deforming to conform to the user's body, for example, by easily changing the body shape (for example, into a chair shape) to fit the user's needs and adjusting it, additional value such as having a function that can change the usage form of the deformable cushion has been considered.

Embodiments for Carrying out the Invention

[0020] Hereinafter, embodiments of the deformable cushion 1 according to the present invention will be described with reference to the drawings. The embodiments described below are an example of embodying the present invention, and do not limit the configuration of the present invention with its specific examples. Also, the front-rear direction, left-right direction (width direction), and up-down direction in the description are as viewed from the user M sitting on the deformable cushion 1 of the present invention.

[0021] FIGS. 1 to 5 are views schematically showing the outline and usage mode of the deformable cushion 1 of the present invention.

[0022] As shown in Figure 1, the variable-shape cushion 1 of the present invention (sometimes simply referred to as cushion 1) comprises a fluid content, a bag 2 into which the content is placed, and a cushion body 3 formed by combining two or more of these bag 2s.

[0023] The cushion body 3 has a variable shape that allows it to naturally deform to conform to the user M's body shape and posture. The cushion body 3 is approximately half the size of the user M's body. The cushion body 3 is equipped with two or more bag bodies 2 into which contents can be placed. In this embodiment, the cushion body 3 consists of four bag bodies 4 to 7.

[0024] In this embodiment, the bag 2 is not densely filled with contents, but rather contains less contents than the internal volume of the bag 2, leaving some extra space inside, thus providing overall roominess. As a result, the cushion 3 (cushion 1) naturally deforms to conform to the user M's body shape and posture.

[0025] Bag 2 is made by sewing together cloth or plastic sheets to form a bag shape. Various materials can be used for bag 2, but cotton broadcloth is a suitable choice. The elasticity of bag 2 can be adjusted as needed depending on the design requirements.

[0026] Various shapes can be used for the bag body 2. The shape of the bag body 2 can be created arbitrarily by cutting and sewing the fabric material. As shown in Figure 1, the bag body 2 can be roughly triangular pyramidal in shape, and when the user M sits down, the contents inside shift, and the cushion 1 deforms to cover the buttocks and lower back.

[0027] As shown in Figures 1 to 4, the bag 2 of this embodiment includes a first bag 4 that is large enough to support the buttocks of the user M, a second bag 5 that extends in a communication manner from the first bag 4 to the rear, a third bag 6 that is provided in a communication manner to the left side of the first bag 4, and a fourth bag 7 that is provided in a communication manner to the right side of the first bag 4.

[0028] In other words, the bag body 2 (cushion body 3) of this embodiment is divided into four compartments, and the first bag body 4, the second bag body 5, the third bag body 6, and the fourth bag body 7 are all connected to each other.

[0029] However, the bag 2 may be made from a single sheet material and divided into four compartments (first bag 4 to fourth bag 7), or it may be made by joining together four first bag 4 to fourth bag 7. In this embodiment, it is divided into four parts: first bag 4, second bag 5, third bag 6, and fourth bag 7, but at least two or more parts are sufficient.

[0030] The first bag 4 is large enough for user M to sit on. In other words, the first bag 4 becomes a seat when user M sits on it. This first bag 4 is constructed by layering two pieces of cloth (a thin, flexible sheet material) cut into a roughly rectangular shape and sewing the edges together. The inside of this first bag 4 is filled with beads (details will be described later).

[0031] The second bag 5 takes on a roughly triangular pyramidal shape when the user M is seated on the first bag 4, and is sized to support the user's back. In other words, the second bag 5 becomes the backrest when the user M is seated on the first bag 4.

[0032] This second bag 5 is made by layering two pieces of cloth (a thin, flexible sheet material) that have been cut so that their ends (the side that moves away from the first bag 4) are spindle-shaped, and sewing the edges together. Beads are placed inside this second bag 5. The second bag 5 is connected to the first bag 4, and the beads can move between the second bag 5 and the first bag 4.

[0033] A third bag-like structure 6 is provided to the left of the first bag-like structure 4. The third bag-like structure 6 extends to the left from the first bag-like structure 4. When the user M is seated on the first bag-like structure 4, the third bag-like structure 6 takes on a roughly triangular pyramidal shape. That is, when the user M is seated on the first bag-like structure 4, the third bag-like structure 6 is positioned to surround the left side of the user M's buttocks. The third bag-like structure 6 can also be used as a left armrest.

[0034] This third bag 6 is made by layering two pieces of cloth (a thin, flexible sheet material) that have been cut so that their ends (the side that moves away to the left from the first bag 4) are spindle-shaped, and sewing the edges together. Beads are placed inside this third bag 6. The third bag 6 is also connected to the first bag 4, and the beads can move between the third bag 6 and the first bag 4.

[0035] A fourth bag 7 is provided to the right of the first bag 4. The fourth bag 7 has a similar shape to the third bag 6, but mirrored horizontally. The fourth bag 7 is provided so as to extend to the right from the first bag 4. When the user M is seated on the first bag 4, the fourth bag 7 takes on a roughly triangular pyramidal shape. That is, when the user M is seated on the first bag 4, the fourth bag 7 is positioned to surround the right side of the user M's buttocks. The fourth bag 7 can also be used as a right armrest.

[0036] This fourth bag 7 is made by layering two pieces of cloth (a thin, flexible sheet material) that have been cut so that their ends (the side that moves away to the right from the first bag 4) are spindle-shaped, and sewing the edges together. Beads are placed inside this fourth bag 7. Furthermore, the fourth bag 7 is in communication with the first bag 4, and the beads can move between the fourth bag 7 and the first bag 4.

[0037] In other words, the first bag 4 and the second bag 5, the first bag 4 and the third bag 6, and the first bag 4 and the fourth bag 7 are all connected, and the beads move freely within the first bag 4 to the fourth bag 7. Note that the shape of the cushion body 3 in this embodiment, that is, the shape, material, and arrangement of the first bag 4 to the fourth bag 7, is just an example and is not limited thereto.

[0038] The first bag 4 to the fourth bag 7 (bag 2) described above contain a fluid contents (filling). Beads are enclosed as fillers. Various materials can be used for these beads. For example, polystyrene foam granules, polyethylene granules, and granular pipes are suitable, all with a diameter of several millimeters to several centimeters. Regarding the contents, any fluid material can be used, not limited to the examples given.

[0039] The amount of beads used to enclose the first to fourth bags 4 and 7 of cushion 1 is approximately 50-90% of the total volume of the bags 4 to 4 and 7. A gap is intentionally left within the bags 4 to 4 and 7 to allow the beads to move easily. The amount of beads can be changed as needed.

[0040] In other words, the amount of beads (contents) is less than the volume of the first bag 4 to the fourth bag 7. Furthermore, the beads function as cushion 1 and are also designed to be movable within the first bag 4 to the fourth bag 7. However, the material and amount of beads should be determined considering factors such as seating comfort.

[0041] Due to this configuration, cushion 1 can freely change its shape. For example, as shown in Figures 1 to 5, user M can move the beads inside with their hands to freely deform the cushion, or user M can put their weight on cushion 1, allowing cushion 1 to naturally change shape to conform to the shape of user M's body (body type and posture) and fit snugly to it.

[0042] In particular, in the case of the cushion body 3 of this embodiment, when user M sits on the first bag body 4 which serves as the seat (when a load is applied to the first bag body 4 via user M's buttocks), the beads that were inside the first bag body 4 move to the second bag body 5 which serves as the backrest, and also move to the left and right third bag bodies 6 and fourth bag bodies 7. In the first bag body 4 which serves as the seat, a large amount of beads move due to the weight of the user M sitting on it, so the amount of beads in the first bag body 4 is less than that in the second bag bodies 5 to the fourth bag bodies 7.

[0043] The moving beads will fill each of the second bags 5 to the fourth bags 7 (almost filling their volume). The moving beads will cause the second bag 5 to extend backward and stand upright. Since the user M's back is in front of the upright second bag 5, the second bag 5 will become a backrest that supports the user M's back.

[0044] Furthermore, the third bag 6 is deformed and positioned so as to extend to the left and rise upward due to the moving beads. Similarly, the fourth bag 7 is deformed and positioned so as to extend to the right and rise upward due to the moving beads.

[0045] The third bag 6 and the fourth bag 7 are deformed and arranged so that they face each other in the width direction. Since the user M's buttocks are located between the third bag 6 and the fourth bag 7, the third bag 6 and the fourth bag 7 are positioned to sandwich the user M's buttocks.

[0046] As for cushion 1, a hollow polyvinyl chloride material filled with a liquid (fluid) such as water may also be used. As long as the fluid inside can move spatially, the bag body 2 (cushion body 3) can be freely deformed and can be freely deformed to conform to the posture and body shape of the user M.

[0047] The cushion body 3 of this embodiment is provided with a restricting member that divides the bag body 3 into at least two or more bag bodies to restrict the movement of the contents. The restricting member of this embodiment consists of a first restricting member 8, a second restricting member 11, and a third restricting member 14, which will be described later.

[0048] In this embodiment, the cushion body 3 is provided with a first restricting member 8 that divides the bag body 2 into a first bag body 4 and a second bag body 5 (two compartments), thereby restricting the movement of the beads. The second bag body 5 is provided behind the first bag body 4 by the first restricting member 8.

[0049] In this embodiment, the first limiting member 8 is provided at the point where the first bag 4 and the second bag 5 switch places (the point where they communicate). In other words, it can be said that the first limiting member 8 separates one bag 2 into the first bag 4 and the second bag 5.

[0050] The first restricting member 8 restricts the movement of the beads placed inside the bag 2, thereby maintaining the shape of the bag on the side with the increased number of beads (in this case, the second bag 5).

[0051] For example, within the interior of bag 2, the beads on the side that will become the first bag 4 are moved to the side that will become the second bag 5, and the movement of the beads is restricted by the first restricting member 8, so that the shape of the second bag 5 is It forms a well-defined, roughly triangular pyramidal shape.

[0052] In other words, the second bag 5 is shaped by the first restricting member 8 and positioned upright at the rear of the first bag 4. That is, in this embodiment, the first restricting member 8 causes the first bag 4 to become a seat where the user M can sit, and the second bag 5 to become a backrest. By loosening the first restricting member 8, the first bag 4 and the second bag 5 can be returned to a connected state.

[0053] In this embodiment, a long string is used as the first restricting member 8. However, the first restricting member 8 may be a string or a belt, and is not particularly limited as long as it can restrict the movement of the beads by restricting the space between the first bag 4 and the second bag 5.

[0054] At the point where the first bag 4 and the second bag 5 switch places, a long first string insertion section 9 is provided, running from left to right along the left-right direction. The first string insertion section 9 is a long, tunnel-shaped space in the left-right direction that encircles the outside of the switching section.

[0055] The first string 8 is attached by passing through the first string insertion section 9 so as to circle the area where the first bag 4 and the second bag 5 switch places. The end of the first string 8 protrudes outward from the first string opening 10 of the first string insertion section 9, and a handle is provided at this end. In this embodiment, the first string opening 10 is located on the left side. The positions of the first string insertion section 9 and the first string opening 10 can be changed as appropriate.

[0056] For example, the beads are placed together in the first bag 4 and the second bag 5. The proportion of beads placed in each bag 4 and 5 can be changed as desired. By pulling the first string 8 and folding the first string insertion part 9 into an accordion shape, the communication between the first bag 4 and the second bag 5 is restricted, thereby limiting the movement of beads between the two compartments (first bag 4 and second bag 5).

[0057] The first string 8 gives the second bag 5, which now has more beads, a more defined shape, and the first bag 4 and the second bag 5 are positioned independently. In other words, the first bag 4 becomes the seat and the second bag 5 becomes the backrest, forming a cushion 3 that can be sat on.

[0058] Furthermore, when the first string 8 is loosened, the folding of the first string insertion part 9 is released, allowing the first bag 4 and the second bag 5 to communicate, and enabling the movement of the beads.

[0059] The cushion body 3 is provided with a second restricting member 11 that divides the bag body 2 into a first bag body 4 and a third bag body 6 (two compartments), thereby restricting the movement of the beads. The third bag body 6 is positioned to the left of the first bag body 4 by the second restricting member 11.

[0060] In this embodiment, the second limiting member 11 is provided at the point where the first bag 4 and the third bag 6 switch (the point where they communicate). In other words, it can be said that the second limiting member 11 separates one bag 2 into the first bag 4 and the third bag 6.

[0061] The second restricting member 11 restricts the movement of the beads placed inside the bag 2, thereby maintaining the shape of the bag on the side with the increased number of beads (in this case, the third bag 6).

[0062] For example, by moving the beads from the side of the bag body 2 that will become the first bag body 4 to the side that will become the third bag body 6, and then restricting the movement of the beads with the second restricting member 11, the third bag body 6 will take on a neat shape and rise up into a roughly triangular pyramidal shape.

[0063] In other words, the third bag 6 is shaped by the second restricting member 11 and positioned upright on the left side relative to the first bag 4. That is, in this embodiment, the second restricting member 11 makes the first bag 4 a seat where the user M can sit, and the third bag 6 becomes the left wall. By loosening the second restricting member 11, the first bag 4 and the third bag 6 can be returned to a connected state.

[0064] In this embodiment, a long string is used as the second restricting member 11. However, the second restricting member 11 may be a string or a belt, and is not particularly limited as long as it can restrict the movement of the beads by restricting the space between the first bag 4 and the third bag 6.

[0065] At the point where the first bag 4 and the third bag 6 switch places, a long second string insertion section 12 is provided, running from the front to the back along the front-to-back direction. The second string insertion section 12 is a long, tunnel-shaped space in the front-to-back direction that encircles the outside of the switching point.

[0066] The second string 11 is positioned so as to circle the area where the first bag 4 and the third bag 6 switch places. The second string is attached by passing through the insertion section 12. The end of the second string 11 protrudes outward from the second string opening 13 of the second string insertion section 12, and a handle is provided at this end. In this embodiment, the second string opening 13 is located on the rear side. The positions of the second string insertion section 12 and the second string opening 13 can be changed as appropriate.

[0067] For example, the beads are placed together in the first bag 4 and the third bag 6. The proportion of the beads placed in each of the bags 4 and 6 can be changed as desired. By pulling the second string 11 and folding the second string insertion part 12 in an accordion shape, the communication between the first bag 4 and the third bag 6 is restricted, thereby limiting the movement of the beads between the two compartments (first bag 4 and third bag 6).

[0068] The second string 11 gives the third bag 6, which now has more beads, a more organized shape, and the first bag 4 and the third bag 6 are positioned independently of each other. In other words, the third bag 6 stands upright relative to the first bag 4. When the user M is seated on the first bag 4, the third bag 6 is positioned to surround the left side of the user M's buttocks.

[0069] Furthermore, when the second string 11 is loosened, the folding of the second string insertion part 12 is released, allowing the first bag 4 and the third bag 6 to communicate, and enabling the movement of the beads.

[0070] The cushion body 3 is provided with a third restricting member 14 that divides the bag body 2 into a first bag body 4 and a fourth bag body 7 (two compartments), thereby restricting the movement of the beads. The fourth bag body 7 is positioned to the right of the first bag body 4 by the third restricting member 14.

[0071] In this embodiment, the third limiting member 14 is provided at the point where the first bag 4 and the fourth bag 7 switch (the point where they communicate). In other words, it can be said that the third limiting member 14 separates one bag 2 into the first bag 4 and the fourth bag 7.

[0072] The third restricting member 14 restricts the movement of the beads placed inside the bag 2, thereby maintaining the shape of the bag on the side with the increased number of beads (in this case, the fourth bag 7).

[0073] For example, by moving the beads from the side of the bag body 2 that will become the first bag body 4 to the side that will become the fourth bag body 7, and then restricting the movement of the beads with the third limiting member 14, the fourth bag body 7 will take on a neat shape and rise up into a roughly triangular pyramidal shape.

[0074] In other words, the fourth bag 7 is shaped by the third restricting member 14 and positioned upright to the right of the first bag 4. That is, in this embodiment, the third restricting member 14 makes the first bag 4 a seat where the user M can sit, and the fourth bag 7 becomes the right wall. By loosening the third restricting member 14, the first bag 4 and the fourth bag 7 can be returned to a connected state.

[0075] In this embodiment, a long string is used as the third restricting member 14. However, the third restricting member 14 may be a string or a belt, and is not particularly limited as long as it can restrict the movement of the beads by restricting the space between the first bag 4 and the fourth bag 7.

[0076] At the point where the first bag body 4 and the fourth bag body 7 switch places, a long third string insertion section 15 is provided, running from the front to the back along the front-to-back direction. The third string insertion section 15 is a long, tunnel-shaped space in the front-to-back direction that encircles the outside of the switching section.

[0077] The third string 14 is attached by passing through the third string insertion section 15 so as to circle the area where the first bag 4 and the fourth bag 7 switch places. The end of the third string 14 protrudes outward from the third string opening 16 of the third string insertion section 15, and a handle is provided at this end. In this embodiment, the third string opening 16 is located on the rear side. The positions of the third string insertion section 15 and the third string opening 16 can be changed as appropriate.

[0078] For example, the beads are placed together in the first bag 4 and the fourth bag 7. The proportion of beads placed in each of the bags 4 and 7 can be changed as desired. By pulling the third string 14 and folding the third string insertion part 15 into an accordion shape, the communication between the first bag 4 and the fourth bag 7 is restricted, thereby limiting the movement of beads between the two compartments (first bag 4 and fourth bag 7).

[0079] The third string 14 gives the fourth bag 7, which now has more beads, a more organized shape, and the first bag 4 and the fourth bag 7 are arranged independently. In other words, the fourth bag 7 is the The fourth bag 7 is shaped to stand up relative to the first bag 4. When the user M is seated in the first bag 4, this fourth bag 7 is positioned to surround the right side of the user M's buttocks.

[0080] Furthermore, when the third string 14 is loosened, the folding of the third string insertion part 15 is released, allowing the first bag 4 and the fourth bag 7 to communicate, and enabling the movement of the beads.

[0081] In other words, the third bag 6, which is independent by the second string 11, and the fourth bag 7, which is independent by the third string 14, deform to surround the first bag 4, which serves as the seat, from the left and right sides. As a result, the third bag 6 and the fourth bag 7 are positioned to envelop the buttocks of the user M.

[0082] Note that the shape, material, arrangement, etc., of the restricting members 8, 11, 14 (string bodies 8, 11, 14), string insertion parts 9, 12, 15, and string openings 10, 13, 16 in this embodiment are examples only and are not limited thereto.

[0083] Furthermore, each of the restricting members 8, 11, and 14 is a means of restricting the movement of the contents (beads) placed inside the bag 2, and in addition to the strings and belts exemplified in this embodiment, the following structures are also possible.

[0084] For example, one method is to provide zippers as restricting members 8, 11, and 14 on the bag body 2, and restrict the movement of beads inside the bag body 2 by opening and closing the zippers. Another method is to provide buttons as restricting members 8, 11, and 14 on the bag body 2, and restrict the movement of beads inside the bag body 2 by opening and closing the buttons.

[0085] In this way, by providing restricting members 8, 11, and 14 to the bag body 2 in which the beads are placed, the user M can create a shape that suits their preference (a shape that allows them to relax) in the bead cushion 1, which has a degree of freedom, and the shape can be reliably maintained. [Usage Pattern] The usage of the cushion 1 of this embodiment, as described above, will now be explained with reference to the drawings. This usage of the cushion 1 is just one example and is not limited thereto.

[0086] In this embodiment, the restricting members 8, 11, 14 (strings 8, 11, 14) described above allow the shape of the cushion body 3 to be pre-deformed into any desired shape before use.

[0087] For details, we will start from the state shown in Figure 2, where strings 8, 11, and 14 are not used. First, we will describe the case when using the first string 8. Gather the beads towards the first bag 4 and the second bag 5, respectively. For example, move more beads to the second bag 5.

[0088] As shown in Figure 3, when you grasp the handle of the first string 8 and pull the first string 8, the first string 8 is pulled out from the first string opening 10, and the first string insertion part 9 is folded in an accordion shape. In other words, the first bag 4 and the second bag 5 are in a state similar to a drawstring bag that has been tied.

[0089] This restricts the communication between the first bag 4 and the second bag 5, limiting the movement of beads between them, and the first string 8 (first restricting member 8) maintains the shape of the second bag 5, which has more beads. As a result, the first bag 4 and the second bag 5 become independent of each other. However, they can still be used in this state, and when user M sits down and puts their weight on the first bag 4, the first bag 4 becomes the seat and the second bag 5 becomes the backrest.

[0090] Next, we will describe the case where the second string 11 and the third string 14 are used in addition to the first string 8. First, gather the beads together in the first bag 4, the second bag 5, the third bag 6, and the fourth bag 7, respectively. For example, move more beads to the second bag 5, the third bag 6, and the fourth bag 7. The procedure for using the first string 8 is as described above.

[0091] As shown in Figure 4, when you grasp the handle of the second string 11 and pull the second string 11, the second string 11 is pulled out from the second string opening 13, and the second string insertion part 12 folds into an accordion shape. In other words, the first bag 4 and the third bag 6 are in a state similar to a drawstring bag that has been tied.

[0092] This restricts the communication between the first bag 4 and the third bag 6, restricts the movement of beads between the first bag 4 and the third bag 6, and the second string 11 (second restricting member 11) maintains the shape of the third bag 6, which has more beads. As a result, the first bag 4 and the third bag 6 become independent of each other. The third bag 6 is positioned to surround the left side of the user M's buttocks when the user M is seated in the first bag 4.

[0093] Next, by grasping the handle of the third string 14 and pulling the third string 14, the third string 14 is pulled out from the third string opening 16, and the third string insertion part 15 is folded in an accordion shape. In other words, the first bag 4 and the fourth bag 7 are in a state similar to a drawstring bag that has been tied.

[0094] This restricts the communication between the first bag 4 and the fourth bag 7, restricts the movement of beads between the first bag 4 and the fourth bag 7, and the second string 11 (second restricting member 11) maintains the shape of the third bag 6, which has more beads. As a result, the first bag 4 and the fourth bag 7 become independent of each other. The fourth bag 7 is positioned to surround the right side of the user M's buttocks when the user M is seated in the first bag 4.

[0095] In this way, when user M sits on cushion 1, which has been pre-deformed using straps 8, 11, and 14, it conforms more easily to user M's body, allowing them to lean against the more upright second bag 5. Furthermore, as the third bag 6 and fourth bag 7 rise more, user M's buttocks are more deeply enveloped, allowing for a more comfortable posture during use.

[0096] Furthermore, loosening the first string 8 releases the folding of the first string insertion section 9, loosening the second string 11 releases the folding of the second string insertion section 12, and loosening the third string 14 releases the folding of the third string insertion section 15, so that all of the first to fourth bags 4 to 7 are connected, and the beads can be moved (see Figure 2).

[0097] Furthermore, in this embodiment, the cushion 1 can be used even without using the strings 8, 11, and 14. In the state shown in Figure 2, user M puts their weight on the first bag 4, which serves as the seat, and sits down on the cushion 3. At this time, some of the beads move into the second bag 5, third bag 6, and fourth bag 7, respectively, due to the weight of user M inside the first bag 4. The second bag 5 becomes filled with the moved beads. Similarly, the third bag 6 and fourth bag 7 also become filled with the moved beads.

[0098] As a result, the second bag 5 extends backward and rises upward, becoming a backrest that supports the user M's back. The third bag 6 also deforms to extend to the left and rises upward, and is positioned to surround the left side of the user M's buttocks. The third bag 6 may also be used as a left armrest.

[0099] Similarly, the fourth bag 7 deforms to extend to the right and rise upward, and is positioned to surround the right side of the user M's buttocks. The fourth bag 7 may also be used as a right armrest.

[0100] As shown in Figure 5, when user M sits on cushion 1, it naturally deforms to conform to user M's body, allowing M to lean against the second bag 5, and the third bag 6 and fourth bag 7 envelop user M's buttocks, so it can be used in a comfortable posture.

[0101] As described above, the variable-shape cushion 1 of the present invention, in a cushion that naturally deforms to conform to the user M's body, has a function that allows the main body shape to be easily pre-deformed and adjusted to any shape (for example, a chair shape), i.e., it is equipped with limiting members 8, 11, 14 (string members 8, 11, 14), so that it can be used in a more comfortable posture, thereby further improving the relaxation effect.

[0102] Furthermore, the variable-shape cushion 1 of the present invention can also prevent the movement of the beads by restricting the flow of beads between the first bag 4 and the fourth bag 7 with the respective restricting members 8, 11, and 14 before the beads are moved. This makes it possible to easily change the shape of the variable-shape cushion 1.

[0103] If the flow of beads is not restricted by the restricting members 8, 11, and 14, when a user sits on the first bag 4, the beads inside the first bag 4 are pushed out into the second bag 5, the third bag 6, and the fourth bag 7, respectively.

[0104] In this case, for example, if the flow of beads in the first bag 4 and the second bag 5 is restricted by the first restricting member 8, when the user sits in the first bag 4, the flow rate of beads from the first bag 4 to the second bag 5 is restricted, and the flow rate (amount of beads moving) to the third bag 6 and the fourth bag 7 increases accordingly.

[0105] Then, the third bag 6 and the fourth bag 7 on the left and right stand up (bulge), but the bead inflow to the second bag 5 at the back decreases, so the standing up (bulging) of the second bag 5 is controlled by the first control. This is reduced compared to the case where the limiting member 8 is not used. In other words, the second bag body 5, which serves as the backrest, becomes closer to a reclined position, and the user is in a posture similar to lying on their back.

[0106] Since the flow rate of the beads (the amount the beads move) changes depending on the degree of restriction by each limiting member 8, 11, and 14, the degree to which the second bag 5 rises can be adjusted by adjusting the first limiting member 8 (for example, if the first limiting member 8 is implemented with the first string 8, the inner length of the string that forms the drawstring and the strength of the knot).

[0107] Similarly, when the flow rate of beads from the first bag 4 to the third bag 6, or from the first bag 4 to the fourth bag 7, is restricted by the second limiting member 11 or the third limiting member 14, the rise of the third bag 6 or the fourth bag 7 is suppressed.

[0108] In this way, by using the respective limiting members 8, 11, and 14, when a load is applied to any of the bags 4 to 7, it is possible to selectively adjust the destination of the beads flowing out of that bag 4 to 7, as well as the amount of beads flowing into that bag 4 to 7 (for example, when beads flow out of the first bag 4, the destination of the beads flowing into the other bags 5 to 7 and the amount of beads moving into those bags 5 to 7), thereby enabling the creation of the shape of the bead cushion 1 freely.

[0109] Various improvements may be made to the cushion 1 of the present invention. For example, the bag 2 may be equipped with a massage mechanism, although this is not shown in the figure.

[0110] Specifically, a fifth bag (not shown) containing a massage mechanism is provided on the outside or inside of the bag 2 containing the contents (beads). That is, the massage mechanism is located in the bag 2 via the fifth bag. Furthermore, the massage mechanism is preferably movable within the fifth bag.

[0111] For example, if a fifth bag containing a massage mechanism is placed on the outside of the first bag 4, the buttocks and other areas can be massaged. Also, if a fifth bag containing a massage mechanism is placed on the outside of the second bag 5, the back and other areas can be massaged.

[0112] Furthermore, the fifth bag may be equipped with a device limiting member (not shown) that restricts the movement of the massage mechanism. The device limiting member allows the position of the massage mechanism to be set arbitrarily.

[0113] For example, the interior of the bag body 2 (cushion body 3) may be configured to accommodate a massage mechanism (either mechanical or airbag type) capable of providing a massage to the user M. That is, at least the interior of one of the first bag body 4 to the fourth bag body 7 should be configured to movably house a massage mechanism.

[0114] The massage mechanism is designed to move between the first bag 4 and the second bag 5, which are connected in a manner, and the first string 8 (first limiting member 8) allows it to be moved and positioned inside either the first bag 4 or the second bag 5.

[0115] For details, we will start from the state shown in Figure 2, where the first string 8 is not being used. For example, move the massage mechanism to the second bag 5. It is also a good idea to move the beads to the second bag 5. That is, by moving a slightly larger number of beads to the second bag 5, the massage mechanism will be positioned closer to the surface that comes into contact with the back.

[0116] As shown in Figure 3, when you grasp the handle of the first string 8 and pull it, the first string 8 is pulled out from the first string opening 10, and the first string insertion part 9 is folded in an accordion shape. The first bag 4 and the second bag 5 then take on a state similar to a drawstring bag that has been tied.

[0117] This restricts the communication between the first bag 4 and the second bag 5, and the massage mechanism is positioned inside the second bag 5. The first bag 4 and the second bag 5 become independent of each other. In this state, when user M sits down and puts their weight on the first bag 4, the first bag 4 becomes the seat and the second bag 5 becomes the backrest. The massage mechanism comes into contact with user M's back, allowing them to receive a back massage.

[0118] Furthermore, if the massage mechanism is moved to the first bag 4 and the above procedure is performed, the first bag 4 will become the seat, and the massage mechanism will come into contact with the user M's buttocks, allowing the user M to receive a massage on their buttocks.

[0119] Furthermore, when the massage mechanism is moved and positioned in the third bag 6, the movement of the massage mechanism from the third bag 6 is restricted using the second string 11, allowing the massage to be directed to the desired treatment area. You can receive the service.

[0120] Furthermore, when the massage mechanism is moved to the fourth bag 7 and positioned there, the movement of the massage mechanism from the fourth bag 7 is restricted using the third string 14, allowing the massage to be applied to the desired treatment area.

[0121] Furthermore, it is also preferable to have a double-layered structure for the bag 2. In the case of a double-layered structure, the outer fabric (outer cover) can be a removable cover for washing, and the inner fabric (inner cover) can be the bag 2 containing the beads.

[0122] However, each restricting member 8, 11, 14 (for example, a string or belt) that restricts the movement of the contents (beads) within the bag 2 may be provided on either the outer fabric (outer cover) or the inner fabric (inner cover).

[0123] It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects. In particular, matters not explicitly disclosed in the embodiments disclosed herein, such as operating conditions, various parameters, dimensions, weight, and volume of components, do not deviate from what is normally practiced by those skilled in the art, and the values ​​adopted are those that can be easily anticipated by those skilled in the art.

[0124] However, the naming conventions for the first bag 4 to the fourth bag 7 and the first restricting member 8 to the third restricting member 14 in this embodiment are merely for convenience in explaining the present invention, and the naming conventions are arbitrary. [Explanation of symbols]
