Embodiments for Carrying out the Invention

[0010] The clothing attachment / detachment device described in this specification is a device that enables a seated person sitting on a chair or the like to attach and detach clothing such as pants, a skirt, or a diaper while remaining seated. Specifically, the clothing attachment / detachment device creates a clearance for attachment / detachment for attaching and detaching clothing between the waist of the seated person and the mat, and further, the clearance for attachment / detachment can be moved in the front-rear direction.

[0011] [1 Configuration] Figure 1 is a schematic configuration diagram of the clothing attachment / detachment device 10. The clothing attachment / detachment device 10 includes a seating mat 12, a supply / discharge mechanism 14, a battery 16, a control unit 18, and an input device 46.

[0012] The seating mat 12 is placed on the seat portion 54 (Figure 2B, etc.). In the seating mat 12, the up-down, front-rear, and left-right directions are each predetermined. In a state where the seating mat 12 is placed on the seat portion 54 and the seated person 50 (Figure 2B, etc.) is seated on the seating mat 12, the waist of the seated person 50 is located above the seating mat 12, and the knees of the seated person 50 are located in front of the seating mat 12. In the following description, the directions of "front-rear", "left-right", and "up-down" mean the directions in a state where the seating mat 12 is placed on the seat portion 54.

[0013] The seating mat 12 includes a base 20 and a plurality of airbags 22. The base 20 is harder than the airbags 22 while having flexibility. Note that the base 20 may not have flexibility. The base 20 supports the plurality of airbags 22 on the mounting surface 24. The mounting surface 24 of the base 20 faces upward.

[0014] The plurality of airbags 22 are attached to the mounting surface 24 of the base 20. Some or all of the plurality of airbags 22 may be detachable from the mounting surface 24 of the base 20. The plurality of airbags 22 are arranged in a matrix on the mounting surface 24 of the base 20. In the present embodiment, nine airbags 22 are arranged in a 3×3 matrix. That is, the nine airbags 22 are arranged in three rows in the front-rear direction and the left-right direction.

[0015] In this specification, among the three rows of airbags 22 arranged along the left-right direction, the three airbags 22 arranged on the rearmost side are referred to as rear airbags 22r (the first airbag, the third airbag). Also, among the three rows of airbags 22 arranged along the left-right direction, the three airbags 22 arranged on the foremost side are referred to as front airbags 22f (the third airbag, the first airbag). Further, the three airbags 22 arranged between the three rear airbags 22r and the three front airbags 22f are referred to as middle airbags 22m (the second airbag). In the three columns along the front-rear direction, the rear airbags 22r are adjacent to the middle airbags 22m, and the middle airbags 22m are adjacent to the front airbags 22f.

[0016] The air supply and discharge mechanism 14 includes a pump 26, six valves 28a to 28f, and a pressure sensor 30. The pump 26 is a positive and negative pressure pump that can supply and suck air. Note that a positive pressure pump capable of supplying air and a negative pressure pump capable of sucking air may be provided separately. Each of the six valves 28a to 28f is a solenoid valve that operates in response to a signal supplied from the control unit 18. The valves 28a to 28f have a position (referred to as an open position) in which the pump 26 and the airbag 22 communicate with each other and a position (referred to as a closed position) in which the pump 26 and the airbag 22 are blocked from each other. The pressure sensor 30 measures the pressure of the air supplied from the pump 26 to the airbag 22 and outputs the measurement result to the control unit 18.

[0017] The port of the pump 26 is connected to the main flow path 32. A pressure sensor 30 is connected to the main flow path 32. The main flow path 32 is connected to each of the six branch flow paths 34a to 34f.

[0018] The branch flow path 34a is connected to the first port of the valve 28a. The second port of the valve 28a is connected to the airbag flow path 36a. The airbag flow path 36a is connected to each of the two rear airbags 22r located at the left and right ends among the three rear airbags 22r.

[0019] The branch flow path 34b is connected to the first port of the valve 28b. The second port of the valve 28b is connected to the airbag flow path 36b. The airbag flow path 36b is connected to each of the two middle airbags 22m located at the left and right ends among the three middle airbags 22m.

[0020] The branch flow path 34c is connected to the first port of the valve 28c. The second port of the valve 28c is connected to the airbag flow path 36c. The airbag flow path 36c is connected to each of the two front airbags 22f located at the left and right ends among the three front airbags 22f.

[0021] The branch flow path 34d is connected to the first port of the valve 28d. The second port of the valve 28d is connected to the airbag flow path 36d. The airbag flow path 36d is connected to the rear airbag 22r located in the middle among the three rear airbags 22r.

[0022] The branch flow path 34e is connected to the first port of the valve 28e. The second port of the valve 28e is connected to the airbag flow path 36e. The airbag flow path 36e is connected to the middle airbag 22m located in the middle among the three middle airbags 22m.

[0023] The branch flow path 34f is connected to the first port of the valve 28f. The second port of the valve 28f is connected to the airbag flow path 36f. The airbag flow path 36f is connected to the front airbag 22f located in the middle of the three front airbags 22f.

[0024] The battery 16 supplies power to the electric / electronic devices provided in the garment attachment / detachment device 10. In the present embodiment, the battery 16 supplies power to the pump 26 and the control unit 18. Although not shown, the battery 16 also supplies power to each of the valves 28a to 28f and the pressure sensor 30.

[0025] The control unit 18 is provided with, for example, an arithmetic unit 38 and a storage unit 40.

[0026] The arithmetic unit 38 can be configured by a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). That is, the arithmetic unit 38 can be configured by a processing circuitry.

[0027] The arithmetic unit 38 is provided with a pump control unit 42 and a valve control unit 44. The pump control unit 42 and the valve control unit 44 can be realized by a program stored in the storage unit 40 being executed by the arithmetic unit 38. The pump control unit 42 controls the operation of the pump 26. The valve control unit 44 controls the operation of each of the valves 28a to 28f.

[0028] Note that at least a part of the pump control unit 42 and the valve control unit 44 may be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). Also, at least a part of the pump control unit 42 and the valve control unit 44 may be configured by an electronic circuit including discrete devices.

[0029] The storage unit 40 may be composed of a volatile memory (not shown) and a non-volatile memory (not shown). Examples of the volatile memory may include a RAM (Random Access Memory). This volatile memory is used as the working memory of the processor and temporarily stores data and the like necessary for processing or calculation. Examples of the non-volatile memory may include a ROM (Read Only Memory), a flash memory, and the like. This non-volatile memory is used as a storage memory and stores programs, tables, maps, and the like. At least a part of the storage unit 40 may be provided in the above-described processor, integrated circuit, or the like.

[0030] Regarding each mode (undressing mode, dressing mode, hip wiping mode) described later, the storage unit 40 stores in advance information indicating an arrangement pattern showing the arrangement of the inflated airbag 22 (inflated airbag) and the arrangement of the deflated airbag 22 (deflated airbag). Further, the storage unit 40 stores in advance information indicating the switching order of the arrangement patterns regarding modes (undressing mode, dressing mode) that require switching between a plurality of arrangement patterns.

[0031] The input device 46 includes a switch operable by a user (the seated person 50 or a caregiver who cares for the seated person 50). The input device 46 outputs a signal corresponding to the switch operation performed by the user to the control unit 18.

[0032] [2 Operations] The clothing attachment / detachment device 10 is capable of operating in an undressing mode and a dressing mode. In each mode, the supply and discharge of air to each airbag 22 may be performed fully automatically or semi-automatically. In the case of full automation, the transition of the arrangement pattern between the inflated airbag and the deflated airbag is automatically performed based on the order information stored in the storage unit 40. In the case of semi-automation, the transition of the arrangement pattern between the inflated airbag and the deflated airbag is performed by the user's switch operation. For example, when the user performs a switch operation, the transition from the first arrangement pattern to the second arrangement pattern is executed.

[0033] The wearing item donning / doffing device 10 is portable. When not in use, each airbag 22 of the seating mat 12 is in a contracted state. The user places the seating mat 12 on the seat part 54 at home or outside.

[0034] [2-1 Undressing mode] The undressing mode is selected when the seated person 50 sitting on the seating mat 12 undresses the wearing item 52 worn around the waist. Hereinafter, the transition of the state (inflation or contraction) of each airbag 22 will be described.

[0035] As shown in FIG. 2B, the seated person 50 sits on the seating mat 12. Initially, as shown in FIG. 2A, each airbag 22 is in a contracted state. The seated person 50 operates the input device 46 to select the execution of the undressing mode. Then, the input device 46 outputs a signal instructing the undressing mode to the control unit 18. The arithmetic unit 38 starts a series of controls described below.

[0036] (First control) The first control is executed first among a series of controls in the undressing mode. By the first control, the arrangement pattern of the inflated airbags and the contracted airbags is set to the state shown in FIGS. 3A and 3B. The valve control unit 44 opens the valves 28a to 28f to put the pump 26 and all the airbags 22 in a communicating state. Further, the pump control unit 42 operates the pump 26 as a positive pressure pump. In this state, the pump 26 supplies air to all the airbags 22. Then, as shown in FIGS. 3A and 3B, all the airbags 22 are in an inflated state. As a result, the seated person 50 is lifted upward.

[0037] When the measured pressure of the pressure sensor 30 becomes equal to or higher than a predetermined pressure stored in the storage unit 40, the valve control unit 44 closes the valves 28a to 28f to cut off the pump 26 from all the airbags 22. Further, the pump control unit 42 stops the pump 26. Then, the states shown in FIGS. 3A and 3B (the state in which all the airbags 22 are inflated) are maintained. That is, the state in which the seated person 50 is lifted upward is maintained.

[0038] (Second Control) The second control is executed after the first control. By the second control, the arrangement pattern of the inflated airbags and the deflated airbags is set to the states shown in FIGS. 4A and 4B. In the second control, the valve control unit 44 closes the valves 28c and 28f to cut off the pump 26 from the front airbag 22f. Similarly, the valve control unit 44 closes the valves 28b and 28e to cut off the pump 26 from the middle airbag 22m. On the other hand, the valve control unit 44 opens the valves 28a and 28d to put the pump 26 in communication with the rear airbag 22r. Further, the pump control unit 42 operates the pump 26 as a negative pressure pump. In this state, the pump 26 sucks air from the rear airbag 22r. Then, as shown in FIGS. 4A and 4B, the three rear airbags 22r transition from the inflated state to the deflated state. On the other hand, the three front airbags 22f and the three middle airbags 22m maintain the inflated state. Thereby, the seated person 50 is supported by the three front airbags 22f and the three middle airbags 22m. On the other hand, a detachable gap 56 is formed between the seated person 50 and the three rear airbags 22r. The detachable gap 56 enables the attachment and detachment of the clothing 52 worn on the waist of the seated person 50. After the detachable gap 56 is formed, the pump control unit 42 stops the pump 26.

[0039] Next, the valve control unit 44 opens the valves 28a and 28d to put the pump 26 and the rear airbag 22r in communication. Further, the pump control unit 42 operates the pump 26 as a positive pressure pump. The pump 26 supplies air to the rear airbag 22r. When the measured pressure of the pressure sensor 30 becomes equal to or higher than a predetermined pressure, the valve control unit 44 closes the valves 28a and 28d to cut off the pump 26 and the rear airbag 22r. Further, the pump control unit 42 stops the pump 26. Then, as shown in FIGS. 3A and 3B, all the airbags 22 are in a once-inflated state.

[0040] (Third Control) The third control is executed after the second control. By the third control, the arrangement pattern of the inflated airbags and the deflated airbags is set to the state shown in FIGS. 5A and 5B. In the third control, the valve control unit 44 closes the valves 28c and 28f to cut off the pump 26 and the front airbag 22f. Similarly, the valve control unit 44 closes the valves 28a and 28d to cut off the pump 26 and the rear airbag 22r. On the other hand, the valve control unit 44 opens the valves 28b and 28e to put the pump 26 and the middle airbag 22m in communication. Further, the pump control unit 42 operates the pump 26 as a negative pressure pump. In this state, the pump 26 sucks air from the middle airbag 22m. Then, as shown in FIGS. 5A and 5B, the three middle airbags 22m transition from an inflated state to a deflated state. On the other hand, the three front airbags 22f and the three rear airbags 22r maintain their inflated states. Thereby, the seated person 50 is supported by the three front airbags 22f and the three rear airbags 22r. On the other hand, a detachable gap 56 is formed between the seated person 50 and the three middle airbags 22m. After the detachable gap 56 is formed, the pump control unit 42 stops the pump 26. In the arrangement pattern shown in FIGS. 5A and 5B, the detachable gap 56 has moved forward compared to the arrangement pattern shown in FIGS. 4A and 4B.

[0041] Next, the valve control unit 44 opens the valves 28b and 28e to put the pump 26 and the middle airbag 22m in communication. Further, the pump control unit 42 operates the pump 26 as a positive pressure pump. The pump 26 supplies air to the middle airbag 22m. When the measured pressure of the pressure sensor 30 becomes equal to or higher than a predetermined pressure, the valve control unit 44 closes the valves 28b and 28e to cut off the pump 26 and the middle airbag 22m. Further, the pump control unit 42 stops the pump 26. Then, as shown in FIGS. 3A and 3B, all the airbags 22 are in a once-inflated state.

[0042] (Fourth Control) The fourth control is executed after the third control. By the fourth control, the arrangement pattern of the inflated airbags and the deflated airbags is set to the state shown in FIGS. 6A and 6B. In the fourth control, the valve control unit 44 closes the valves 28b and 28e to cut off the pump 26 and the middle airbag 22m. Similarly, the valve control unit 44 closes the valves 28a and 28d to cut off the pump 26 and the rear airbag 22r. On the other hand, the valve control unit 44 opens the valves 28c and 28f to put the pump 26 and the front airbag 22f in communication. Further, the pump control unit 42 operates the pump 26 as a negative pressure pump. In this state, the pump 26 sucks air from the front airbag 22f. Then, as shown in FIGS. 6A and 6B, the three front airbags 22f transition from the inflated state to the deflated state. On the other hand, the three middle airbags 22m and the three rear airbags 22r maintain the inflated state. Thereby, the seated person 50 is supported by the three middle airbags 22m and the three rear airbags 22r. On the other hand, a detachable gap 56 is formed between the seated person 50 and the three front airbags 22f. After the detachable gap 56 is formed, the pump control unit 42 stops the pump 26. In the arrangement pattern shown in FIGS. 6A and 6B, the detachable gap 56 has moved forward compared to the arrangement pattern shown in FIGS. 5A and 5B.

[0043] (Undressing Method) The seated person 50 can move the clothing 52 within the range of the attachment / detachment gap 56 toward the knees. By shifting from the first control to the second control, from the second control to the third control, and from the third control to the fourth control, the attachment / detachment gap 56 gradually moves from the waist position to the knee position of the seated person 50. As the attachment / detachment gap 56 moves, the seated person 50 can move the clothing 52 from the waist to the knees to undress.

[0044] [2-2 Clothing mode] The clothing mode is selected when the seated person 50 sitting on the seating mat 12 puts on the clothing 52 around the waist. The seated person 50 operates the input device 46 to select the execution of the clothing mode. Then, the input device 46 outputs a signal instructing the clothing mode to the control unit 18. The arithmetic unit 38 first executes the first control in the above-described undressing mode, then executes the fourth control after the first control, then executes the third control after the fourth control, and then executes the second control after the third control.

[0045] In the clothing mode, first, the arrangement pattern of the inflatable airbag and the shrinkable airbag transitions from the state shown in FIGS. 2A and 2B to the state shown in FIGS. 3A and 3B. Next, the arrangement pattern of the inflatable airbag and the shrinkable airbag transitions from the state shown in FIGS. 3A and 3B to the state shown in FIGS. 6A and 6B. Next, the arrangement pattern of the inflatable airbag and the shrinkable airbag transitions from the state shown in FIGS. 6A and 6B to the state shown in FIGS. 5A and 5B. Next, the arrangement pattern of the inflatable airbag and the shrinkable airbag transitions from the state shown in FIGS. 5A and 5B to the state shown in FIGS. 4A and 4B.

[0046] The seated person 50 can move the clothing 52 within the range of the attachment / detachment gap 56 toward the waist. By shifting from the first control to the fourth control, from the fourth control to the third control, and from the third control to the second control, the attachment / detachment gap 56 gradually moves from the knee position to the waist position of the seated person 50. As the attachment / detachment gap 56 moves, the seated person 50 can move the clothing 52 from the knees to the waist to dress.

[0047] As described above, according to the clothing attachment / detachment device 10, the seated person 50 can easily undress and dress while remaining seated.

[0048] According to the clothing attachment / detachment device 10, since the airbag 22 is detachable from the base 20, the arrangement pattern of the airbag 22 can be adjusted according to the body shape of the seated person 50.

[0049] [2-3 Other Modes] The clothing attachment / detachment device 10 can also operate in modes other than the undressing mode and the dressing mode. For example, the seated person 50 may wipe their buttocks after undressing the clothing 52. In this case, a space is required between the seating mat 12 and the seated person 50 to bring the hand close to the buttocks of the seated person 50.

[0050] The seated person 50 operates the input device 46 to select the execution of the buttocks wiping mode. Then, the input device 46 supplies a signal instructing the buttocks wiping mode to the control unit 18. By appropriately controlling the valves 28a to 28f by the valve control unit 44 and appropriately controlling the pump 26 by the pump control unit 42, each airbag 22 expands and contracts appropriately.

[0051] In the first buttocks wiping mode, as shown in FIG. 7, a pair of front airbags 22f (end airbags) located at the left and right ends of the three front airbags 22f are inflated. The front airbag 22f (intermediate airbag) located between the pair of front airbags 22f on the left and right of the three front airbags 22f is in a contracted state.

[0052] Similarly, in the first buttocks wiping mode, as shown in FIG. 7, a pair of middle airbags 22m (end airbags) located at the left and right ends of the three middle airbags 22m are inflated. The middle airbag 22m (intermediate airbag) located between the pair of middle airbags 22m on the left and right of the three middle airbags 22m is in a contracted state.

[0053] Similarly, in the first hip wiping mode, as shown in FIG. 7, a pair of rear airbags 22r (end airbags) located at both left and right ends of the three rear airbags 22r are inflated. The rear airbag 22r (middle airbag) located between the pair of left and right rear airbags 22r among the three rear airbags 22r is deflated.

[0054] Thereby, a gap is formed between the airbag 22 located in the middle of each row of the three front airbags 22f, the three middle airbags 22m, and the three rear airbags 22r, and the waist of the seated person 50. The seated person 50 can insert a hand into the gap from the front or the rear to wipe the buttocks.

[0055] In the second hip wiping mode, as shown in FIG. 8, the three front airbags 22f are inflated. Also, the three rear airbags 22r are deflated. Also, a pair of middle airbags 22m located at both left and right ends of the three middle airbags 22m are inflated. The middle airbag 22m (middle airbag) located between the pair of left and right middle airbags 22m among the three middle airbags 22m is deflated.

[0056] Thereby, a gap can be created between the middle airbag 22m located in the middle of the three middle airbags 22m and the waist of the seated person 50, and between the three rear airbags 22r and the waist of the seated person 50. The seated person 50 can insert a hand into the gap from the rear to wipe the buttocks.

[0057] Note that by reversing the front and rear of the inflation / deflation pattern of the plurality of airbags 22 in the second hip wiping mode, the seated person 50 can insert a hand into the gap from the front to wipe the buttocks.

[0058] [3 Others] As shown in FIG. 9, an opening 58 may be formed at the center of the seating mat 12. As a result, the seated person 50 can excrete while leaving the seating mat 12 placed on the toilet seat.

[0059] The number of the airbags 22 is not limited to nine. Also, the arrangement pattern of the plurality of airbags 22 is not limited to a 3×3 matrix. For example, the plurality of airbags 22 may be arranged in a single row along the front-rear direction. Further, the arrangement pattern of the plurality of airbags 22 may be arranged in an n×m (n≧2, m≧2) matrix.
