Description

  In the present invention, an elderly person, a handicapped person, a healthy person whose upper limb is restrained by some work, stands up (hereinafter referred to as “standing”) or sits on a chair (hereinafter referred to as “sitting”). It relates to a chair that reduces the burden on the body by supporting the movement of the time.

  Normally, when the chair has an armrest (armrest) when standing or sitting, the burden on the body can be somewhat reduced by standing or sitting using the armrest. This is because the burden on the lower body when standing or sitting is large, and humans intuitively use the armrest to reduce the burden on the lower body when standing or sitting. However, even when standing or sitting using an armrest, it is impossible to stand or sit unless the lower body has a certain amount of muscle strength. Further, for example, when both hands cannot be freely used while holding an infant or the like, the armrest cannot be used to stand or sit. For this reason, for elderly people with weak muscles, physically handicapped persons, or healthy persons whose upper limbs are restrained by some work, standing or sitting is a heavy burden on the body. Someone could not stand or sit alone without the assistance of another person. In order to allow such people to stand or sit on their own, support chairs have been developed and used that reduce the burden on the body when standing or sitting.

  The leg 140 facilitates movement and rotation of the standing-sitting support chair 10 while a person is sitting on the standing-sitting support chair 110, and facilitates the movement of the standing-sitting support chair 10 main body. A plurality of casters 141 are attached to the leg portion 140. When a person stands up from the standing / sitting support chair 10, the movement and rotation of the leg 140 is automatically locked by the caster lock 150. Further, when a person sits on the standing / sitting support chair 10, the lock of the leg 140 is automatically released.

The caster lock 150 is a caster lock that prevents the standing / sitting support chair 10 from moving or rotating unexpectedly when a person stands up or sits on the standing / sitting support chair 10 from the standing / sitting support chair 10. The mechanism is realized.
A caster lock mechanism realized using the caster lock 150 will be described with reference to FIGS. FIG. 3 (1) shows a state in which the leg 140 is unlocked. FIG. 3 (2) shows a state in which the lock of the leg 140 is operating. In the caster lock mechanism, the caster lock tip 151 of the caster lock 150 is not pressed by a caster lock tip vertical movement mechanism (not shown) in the gear box 161 described later, and the caster lock 150 is not floored as shown in FIG. When the caster lock tip 151 is pressed from a state where it is not in contact with the caster lock, the caster lock 150 is lowered to a position in contact with the floor as shown in FIG. In the caster lock mechanism, the caster lock tip 151 of the caster lock 150 is pressed by a caster lock tip vertical movement mechanism in a gear box 161 described later, and the caster lock 150 is in contact with the floor as shown in FIG. By shifting from the state where the caster lock 150 is not pressed down, the caster lock 150 is raised to a position where it does not contact the floor as shown in FIG.

  The electric actuator 160 includes a caster lock tip vertical movement mechanism in the gear box 161 that moves the caster lock tip 151 in the vertical direction. When the electric actuator 160 receives a command to start standing operation from the control unit 200, the electric actuator 160 moves the caster lock tip 151 downward by the caster lock tip vertical movement mechanism in the gear box 161. In addition, when the electric actuator 160 receives a command for starting the seating operation from the control unit 200, the electric actuator 160 moves the caster lock tip 151 upward by the caster lock tip vertical movement mechanism in the gear box 161. In this way, the caster lock 150 is lowered and moved to a position where it comes into contact with the floor according to the command for starting the standing operation from the control unit 200, or is moved to a position where the caster lock 150 is raised due to the command for starting the seating operation and is not in contact with the floor. The caster lock mechanism is realized by moving.

  The standing seating support mechanism by the link 170 will be described with reference to FIG. FIG. 4A is an enlarged perspective view of the link 170 portion viewed from the left rear side. FIG. 4B is an enlarged perspective view of the link 170 portion viewed from the lower right direction. As shown in FIGS. 4 (1) and 4 (2), the seat surface portion 110 is supported by a gas spring 171, a link 170, and a column base 173 fixed to the skeleton portion crosspiece 102. The gas spring 171 is extendable and reduces the load of the vertical movement of the link 170. Further, a ball caster 171a is provided at the tip of the gas spring 171, and friction with the seat surface portion 110 is reduced by the ball caster 171a. The spring guide 172 suppresses the bending of the gas spring 171 when the gas spring 171 contracts. A support base fixing pin 174 is fixed to the support base 173 and is attached horizontally in the direction of the link 170. The support post fixing pin 174 fixes the link 170 to the support stand 173 so that the link 170 penetrates the link 170 so as to be rotatable about the support stand fixing pin 174 as an axis. A gas spring tip pin hole 177 is provided as an elongated hole at one end of the link 170, and the gas spring tip pin 175 is fixed to the gas spring 171 so as to be movable through the gas spring tip pin hole 177. The other end of the link 170 is provided with a caster lock tip pin hole 178 as an elongated hole, and the caster lock tip pin 176 is fixed to the caster lock tip pin 151 so that the caster lock tip pin hole 178 can move.

Since the link 170 having such a structure is rotatably fixed to the column base 173 by the column base fixing pin 174 about the column base fixing pin 174 as an axis, when the caster lock front end 151 is lowered, the caster lock front end pin 176 is caster caster. Push down the lock end pin hole 178. Along with this operation, the link 170 rotates around the support base fixing pin 174 clockwise as viewed in the drawing of FIG. When the link 170 rotates clockwise, the gas spring tip pin hole 177 rises and pushes up the gas spring tip pin 175. Since the gas spring tip pin 175 is fixed to the gas spring 171, when the gas spring tip pin 175 is pushed up, the rear portion of the seating surface portion 110 rises as the extendable gas spring 171 rises. At this time, the ball caster 171 a provided at the tip of the gas spring 171 can reduce the friction generated when the gas spring 171 pushes up the seat surface portion 110.
When the caster lock tip 151 is raised, the caster lock tip pin 176 pushes up the caster lock tip pin hole 178. Along with this operation, the link 170 rotates around the support base fixing pin 174 counterclockwise as viewed in FIG. As the link 170 rotates counterclockwise, the gas spring tip pin hole 177 is lowered, and the gas spring tip pin 175 is pushed down. Since the gas spring tip pin 175 is fixed to the gas spring 171, when the gas spring tip pin 175 is pushed down, the rear portion of the seat surface portion 110 also descends as the gas spring 171 that can expand and contract is lowered.
The connecting member 179 is fixed to the upper part of the gas spring 171 and has a hole through which the spring guide 172 passes. The connecting member 179 moves while sliding the spring guide 172 passed through the through hole in the vertical direction. When the spring 171 contracts, the spring is restrained.
In this way, the standing seating support mechanism rotates the link 170 clockwise or counterclockwise by moving the caster lock tip 151 up and down by the caster lock tip vertical movement mechanism in the gear box 161, and the seat surface portion 110. Can be moved up and down.

The slide rail 180 is a pair of left and right three parts or a rail folded into a U-shape, and both ends of each slide rail 180 are fixed to the back side of the seat surface portion 110. A slide rail fixing member 181 is attached to each slide rail 180. A through hole for passing the slide rail 180 is provided in the upper part of the slide rail fixing member 181, and the lower part of the slide rail fixing member 181 is fixed to the skeleton beam 103. Further, slide rail wheels 182 that allow the slide rail 180 to move back and forth are attached to the left and right of the back side of the seating surface portion 110, and a slide rail wheel base 183 on which each slide rail wheel 182 moves is provided.
A reclining mechanism realized by using the slide rail 180, the slide rail fixing member 181, the slide rail wheel 182 and the slide rail wheel base 183 will be described with reference to FIG. FIG. 5 (1) is a schematic view of a state in which the backrest 120 is held vertically. FIG. 5 (2) is a schematic view showing a state in which the backrest 120 is inclined rearward. The reclining mechanism uses a word (for example, “reclining” when a person sitting on the standing-sitting support chair 10 enters a reclining state toward the microphone 190 when the reclining portion 120 is tilted backward. ”), The slide rail wheel 182 moves forward on the upper surface of the slide rail wheel base 183 as shown in FIG. Since the slide rail fixing member 181 is fixed to the skeleton beam 103, the slide rail 180 slides through the through hole of the slide rail fixing member 181 and moves forward, so that the backrest 120 can be inclined rearward. Further, when a person sitting on the standing-sitting support chair 10 restores the reclining state of the backrest 120, a word (for example, “return”) used to restore the reclining state toward the microphone 190 is restored. ), The slide rail wheel 182 moves rearward on the upper surface of the slide rail wheel base 183 as shown in FIG. Since the slide rail fixing member 181 is fixed to the skeleton beam 103, the slide rail 180 slides through the through hole of the slide rail fixing member 181 and moves backward, so that the backrest 120 can return to the original position. .
Note that an electric actuator for operating the reclining mechanism is provided separately from the electric actuator 160, but this is not shown.

  The microphone 190 stands up and sits when a person stands up or sits on the upright seating support chair 10 or when the backrest 120 of the upright seating support chair 10 is set in a reclining state or returned. A voice of an instruction word issued by a person to the chair 10 is input. When the voice of the instruction word is input, the microphone 190 converts the input voice into voice data and outputs it to the control unit 200.

  The control unit 200 includes a CPU (Central Processing Unit) or an MPU (Micro-Processing Unit), and includes a voice operation processing unit 201 that outputs an operation command to the electric actuator 160 based on voice data input from the microphone 190. ing. The voice operation process executed by the voice operation processing unit 201 will be described later.

  The storage unit 210 is a non-volatile memory and stores programs executed by the control unit 200, data, and the like. In addition, in order for the standing / sitting support chair 10 to understand the instruction word, the storage unit 210 is provided with a registered sound data storage area 211 for storing the sound data of the word used in the instruction in advance.

  Next, the standing seating support mechanism will be described with reference to FIGS. FIG. 6 is a control configuration diagram of the voice operation processing unit 201 that operates the link 170 by voice input from the microphone 190. The standing / sitting support mechanism is realized by the microphone 190, the control unit 200, the storage unit 210, the electric actuator 160, and the link 170.

  First, the flow when a person stands up from the standing / sitting support chair 10 will be described. When a person stands up from the standing / sitting support chair 10 and utters a word (for example, a voice of “standing”) used when standing up toward the microphone 190, the microphone 190 inputs the voice of the word. The microphone 190 converts the voice of the input word into voice data and outputs it to the control unit 200. When the voice data is input, the control unit 200 analyzes the voice data of words input from the voice data stored in the registered voice data storage area 211 of the storage unit 210 by the voice operation processing unit 201. When the voice operation processing unit 201 determines that the input voice data of the word is “standing”, it outputs a command to start the standing motion to the electric actuator 160. When the electric actuator 160 receives a command to start standing operation, the caster lock tip 151 is moved downward by the caster lock tip vertical movement mechanism in the gear box 161, and the caster lock 150 is lowered to a position in contact with the floor. The part 140 is locked. Further, when the caster lock tip 151 moves downward, the link 170 rotates around the support base fixing pin 174 in the clockwise direction as viewed in FIG. 2 (2b). When the link 170 rotates clockwise, the left and right linear bushes 130 move upward in the cylindrical shaft 132, so that the rear portion of the seating surface portion 110 rises. At the same time, the backrest portion 120 fixed to the linear bush 130 also Ascend upward.

  Next, a flow when a person sits on the standing / sitting support chair 10 will be described. When a person sits on the standing and sitting support chair 10 and utters a word (for example, “sitting” voice) used when sitting toward the microphone 190, the microphone 190 inputs the voice of the word. The microphone 190 converts the voice of the input word into voice data and outputs it to the control unit 200. When the voice data is input, the control unit 200 analyzes the voice data of words input from the voice data stored in the registered voice data storage area 211 of the storage unit 210 by the voice operation processing unit 201. When the voice operation processing unit 201 determines that the voice data of the input word is “sitting”, it outputs a seating operation start command to the electric actuator 160. When the electric actuator 160 receives a command for starting the seating operation, the caster lock tip 151 is moved upward by the caster lock tip vertical movement mechanism in the gear box 161 to raise the caster lock 150 to a position not in contact with the floor. The lock of the leg 140 is released. When the caster lock tip 151 moves upward, the link 170 rotates counterclockwise as viewed in FIG. 2 (1b). As the link 170 rotates counterclockwise around the column base fixing pin 174, the left and right linear bushings 130 move downward in the cylindrical shaft 132, so that the rear portion of the seating surface portion 110 descends. The backrest 120 fixed to the lower part also descends downward.

  Next, voice operation processing executed by the voice operation processing unit 201 of the control unit 200 will be described. Hereinafter, the flowchart of the voice operation process shown in FIG. 7 will be described in the order of steps. First, when the control unit 200 of the standing-sitting support chair 10 that is powered on in advance inputs specific voice data for starting the voice operation processing unit 201 from the microphone 190, for example, “standing” or “sitting”, the voice The operation processing unit 201 is activated. When the voice operation processing unit 201 is activated, the voice operation processing unit 201 starts the voice operation processing.

(Step S10)
The voice operation processing unit 201 extracts registered voice data from the registered voice data storage area of the storage unit 210.

(Step S20)
Next, the voice operation processing unit 201 analyzes the voice data input from the microphone 190 based on the registered voice data extracted in step S10.

(Step S30)
Next, the voice operation processing unit 201 determines whether the voice data input from the microphone 190 has been normally analyzed. When the analysis of the audio data is normally performed (Yes in step S30), the process proceeds to step S40. When the analysis of the voice data is not normally performed (No in step S30), the voice operation process is terminated.

(Step S40)
Next, the voice operation processing unit 201 determines whether the voice data is an instruction to start a standing motion. When the voice data is an instruction to start the standing-up operation (Yes in step S40), the process proceeds to step S50. When the voice data is not an instruction to start the standing motion (No in Step S40), the process proceeds to Step S60.

(Step S50)
Next, the voice operation processing unit 201 outputs a command to start the standing motion to the electric actuator 160 and ends the voice operation process.

(Step S60)
Next, the voice operation processing unit 201 outputs a seating operation start command to the electric actuator 160, and ends the voice operation process.

  As described above, the seat surface portion 110 and the backrest bottom surface portion 120 are raised or lowered in conjunction with each other, so that the burden on the body due to the standing or sitting motion can be reduced while maintaining a stable posture. Further, by interlocking the caster lock mechanism with the standing seating movement, the leg portion 140 moves when standing from the standing seating support chair 10 or when sitting on the standing seating support chair 10, so that the standing or seating is performed. It is possible to prevent the risk of the person falling down from falling backwards. Moreover, since the upright seating support chair 10 of the present invention can be attached with a commercially available caster, it can be replaced with a caster suitable for a usage environment such as a moving distance and a moving direction, and a usage environment such as a floor surface material. it can.
