  Embodiments of the present invention will be described below with reference to the drawings.

  First, with reference to FIG. 1 to FIG. 3, an overall configuration of an upright seating support apparatus 100 according to an embodiment of the present invention will be described.

  The standing / sitting support device 100 is mainly used for a user with weak leg strength, such as a disabled person or an elderly person. The standing / sitting support device 100 supports the user's standing operation and seating operation with respect to the seating portion on which the user is seated. In the present embodiment, the seating part is the toilet seat 2 of the seat-type toilet 1. The seating section is not limited to the toilet seat 2 and may be any seat that can be seated by the user, such as a chair or a sofa.

  The standing / sitting support device 100 is provided in front of the toilet seat 2 and supports the user's thigh, and the support portion 10 is moved up and down linearly so as to be separated from the toilet seat 2 as it rises. The elevating mechanism 20, the frame 30 attached to the installation surface, and the handrail 40 that moves up and down with respect to the frame 30 while supporting the user's arm.

  The standing / sitting support devices 100 are installed on the left and right sides of the toilet seat 2 and operate in synchronization. As shown in FIGS. 1 and 3, the left and right standing seating assistance devices 100 are provided so as to be line symmetric with respect to a center line along the front-rear direction of the toilet seat 2 as a symmetry axis.

  As described above, the standing seating support devices 100 are provided on the left and right sides of the toilet seat 2, so that the user can be firmly supported from the left and right. Therefore, the user can perform the standing motion and the sitting motion with a stable posture.

  Next, the configuration of the standing seating support device 100 on the right side of the toilet seat 2 will be described mainly with reference to FIGS. 4 and 5. Since the standing seating support device 100 on the left side of the toilet seat 2 is configured in the same manner as the standing seating support device 100 on the right side, description thereof is omitted here.

  The support unit 10 supports the vicinity of the base of the user's thigh and supports the user's standing motion and seating motion. The support portions 10 of the left and right standing / sitting support devices 100 support the left and right thighs of the user, respectively. The support part 10 has the contact surface 11 which contact | abuts a user's thigh. The support part 10 can be stowed up to the side of the toilet seat 2 and stored. The raising of the support part 10 will be described in detail later with reference to FIGS.

  The lifting mechanism 20 is provided on the side of the toilet seat 2. The elevating mechanism 20 includes an elevating unit 21 that moves linearly to elevate the support unit 10, a guide unit 22 that guides elevating of the elevating unit 21, and an actuator 23 that elevates the elevating unit 21.

  The proximal end of the elevating part 21 is guided by the guide part 22. The support unit 10 is attached to the tip of the elevating unit 21. A front end portion 25b of a first link 25, which will be described later, is rotatably connected to the elevating unit 21. The elevating part 21 is provided in parallel with the guide part 22.

  The guide part 22 is attached to a base part 31 described later of the frame 30. The guide portion 22 is fixed to the base portion 31 by a pair of rear end support members 22a, a pair of front end support members 22b, and a single lower support member 22c. The guide portion 22 is provided so as to be inclined obliquely forward along the front-rear direction of the toilet seat 2. Thereby, the elevating part 21 is also inclined obliquely forward along the front-rear direction of the toilet seat 2.

  The actuator 23 is a direct acting cylinder driven by an electric motor 23a. The base end of the actuator 23 is rotatably supported by the base portion 31 of the frame 30. The tip of the actuator 23 is pivotally connected to the elevating part 21. When an operation switch (not shown) provided at a position that can be operated by a user or an assistant is operated, the actuator 23 expands and contracts by rotating the electric motor 23a by the electric signal.

  When the actuator 23 extends, the elevating part 21 rises obliquely forward along the guide part 22. Thereby, the support part 10 can be raised and it can support a user's standing operation. On the other hand, when the actuator 23 contracts, the elevating part 21 descends obliquely rearward along the guide part 22. Thereby, it is possible to support the user's sitting operation by lowering the support portion 10.

  In the actuator 23, when the support unit 10 moves to the highest position, a sensor (not shown) detects this, and the supply of current to the electric motor 23a is stopped. Therefore, when the support portion 10 is at the highest position, the actuator 23 does not extend even if the support portion 10 is further raised by the operation of the operation switch. The sensor may be of any type such as a contact sensor or a non-contact sensor.

  In addition, a stopper (not shown) is provided for physically preventing the actuator 23 from extending and raising the support portion 10 in the case where an abnormality occurs in the sensor. This stopper is provided, for example, at an end portion of a linear guide 26c of the second link 26 described later.

  Similarly, in the actuator 23, when the support portion 10 moves to the lowest position and the handrail 40 comes into contact with a stopper member 34 described later, a sensor (not shown) detects this and supplies current to the electric motor 23a. Is stopped. Therefore, when the support portion 10 is at the lowest lowered position, the actuator 23 does not contract even if the support portion 10 is further lowered by the operation of the operation switch. The sensor may be of any type such as a contact sensor or a non-contact sensor.

  The lifting mechanism 20 includes a second link 26 that connects the frame 30 and the handrail 40, a link 30 that connects the frame 30 and the handrail 40, and intersects the second link 26 so that the intersection 28 with the second link 26 is rotatable. And a first link 25 that connects the elevating part 21 and the handrail 40 via the second link 26 and the third link 27.

  The first link 25 moves in conjunction with the movement of the elevating unit 21 to raise and lower the handrail 40. The front end 25b of the first link 25 is rotatably connected to the elevating part 21. The rear end portion 25a of the first link 25 is rotatably connected to the rear end portion 26a of the second link 26.

  The first link 25 moves the rear end part 26a of the second link 26 forward as the elevating part 21 is raised when the support part 10 is raised. On the other hand, when the support part 10 descends, the first link 25 moves the rear end part 26a of the second link 26 backward as the elevating part 21 descends.

  The rear end portion 26a of the second link 26 is connected to the frame 30 via the linear guide 26c so as to be slidable and rotatable in the front-rear direction. The front end portion 26b of the second link 26 is connected to the handrail 40 through a linear guide 26d (see FIG. 6) so as to be slidable and rotatable back and forth.

  In the second link 26, when the support portion 10 is raised, the rear end portion 26 a moves forward and approaches the front end portion 27 b of the third link 27. Thereby, the front end part 26b of the 2nd link 26 raises, and the handrail 40 raises. On the other hand, the second link 26 is separated from the front end portion 27 b of the third link 27 by moving the rear end portion 26 a rearward when the support portion 10 is lowered. Thereby, the front end portion 26b of the second link 26 is lowered, and the handrail 40 is lowered.

  The rear end portion 27a of the third link 27 is rotatably connected to the handrail 40. The front end portion 27 b of the third link 27 is rotatably connected to the frame 30.

  In the third link 27, when the support portion 10 is raised, the rear end portion 27 a moves forward and approaches the front end portion 26 b of the second link 26. At this time, the third link 27 rotates upward about the front end portion 27b. Therefore, the rear end portion 27a of the third link 27 rises in an arc shape with the front end portion 27b as the center, so that the handrail 40 rises while sliding forward. On the other hand, the third link 27 is separated from the front end portion 26b of the second link 26 by moving the rear end portion 27a rearward when the support portion 10 is lowered. At this time, the third link 27 rotates downward about the front end portion 27b. Therefore, the rear end portion 27a of the third link 27 descends in an arc shape centered on the front end portion 27b, so that the handrail 40 descends while sliding backward.

  The elevating mechanism 20 further includes a delay mechanism 29 that raises the handrail 40 with a delay from the support portion 10 when supporting the user's standing operation.

  The delay mechanism 29 is configured by rotating including the position where the first link 25 intersects the elevation unit 21 at a right angle when the support unit 10 rises from the lowest position. When raising the support part 10 from the lowest position, the 1st link 25 rotates to the position which cross | intersects at right angle with respect to the raising / lowering part 21, further rotates from there, and raises the raising / lowering part 21. FIG.

  Until the first link 25 intersects the elevation unit 21 at a right angle, the elevation unit 21 is raised, but the first link 25 pushes the rear end portion 26a of the second link 26 backward. Therefore, the handrail 40 is lowered without being raised. The displacement due to the circular motion around the rear end portion 25 a of the first link 25 is a minute amount with respect to the length of the first link 25. Therefore, the descending amount of the handrail 40 is a size that can be ignored.

  As a delay mechanism, the connecting portion of the rear end portion 25a, the front end portion 25b, or the rear end portion 26a of the second link 26 may be a long hole. In this case, it is possible to prevent the first link 25 from pushing the rear end portion 26a of the second link 26 rearward until the first link 25 intersects the lifting portion 21 at a right angle. Therefore, even if the first link 25 rotates including the position at which the first link 25 intersects at right angles with the elevating part 21 when the support part 10 is raised from the lowest lowered position, the handrail 40 does not fall.

  Further, the first link 25 is rotated without including a position perpendicular to the elevating part 21, and the rear end part 25 a, the front end part 25 b, or the rear end part of the second link 26. The delay mechanism 29 may be configured only by a long hole formed in the connecting portion of the portion 26a.

  The frame 30 includes a base portion 31 fixed to the installation surface, three standing portions 32 standing vertically from the base portion 31, an upper end portion 33 connecting the upper ends of the respective standing portions 32, And a stopper member 34 that supports the handrail 40 when the handrail 40 is lowered to the lowest position.

  The base part 31 is formed in a flat plate shape and is fixed to the installation surface. The base portion 31 is formed in such a size that it does not move relative to the installation surface even when a large force is applied when supporting the user's standing operation and seating operation. When the standing portion 32 of the frame 30 and the elevating mechanism 20 can be directly fixed to the installation surface, the base portion 31 may not be provided.

  All the standing portions 32 are formed to have the same length. The standing portion 32 supports the weight of the user acting on the handrail 40. The standing part 32 does not need to be three, and may be single or plural other than three.

  The upper end portion 33 is provided in parallel with the base portion 31. A rear end portion 26a of the second link 26 is slidably and rotatably connected to the upper surface of the upper end portion 33 via a linear guide 26c, and a front end portion 27b of the third link 27 is rotatably connected. . A stopper member 34 is attached to the upper surface of the upper end portion 33.

  The stopper member 34 is formed in a plate shape, and makes surface contact with the upper end portion 33 and the handrail 40 in a state where the handrail 40 is lowered to the lowest position. The stopper member 34 is erected at an end portion facing the toilet seat 2 on the upper surface of the upper end portion 33. The stopper member 34 is located between the second link 26 and the third link 27 and the user. Therefore, safety during the lifting operation can be improved.

  The handrail 40 is provided above the upper end portion 33 in parallel with the upper end portion 33. A front end portion 26b of the second link 26 is slidably and rotatably connected to the lower surface of the handrail 40 via a linear guide 26d, and a rear end portion 27a of the third link 27 is rotatably connected.

  The handrail 40 is moved up and down in conjunction with the support portion 10 by the lifting mechanism 20. The handrail 40 moves up and down while maintaining a posture parallel to the upper end portion 33. Thereby, the user can perform the standing-up operation and the seating operation in a stable posture while putting the hand on the handrail 40.

  Not limited to this, the handrail 40 may be rotated so that the rear end portion 40a becomes higher as compared with the front end portion 40b as it rises. The handrail 40 can be rotated at the time of ascending and descending by providing the intersection portion 28 of the second link 26 and the third link 27 offset forward.

  In this way, when the handrail 40 is rotated during ascent and descent, the handrail 40 operates so as to follow the user's standing operation and seating operation. Therefore, the user can perform the standing motion and the sitting motion with a more stable posture.

  Next, mainly with reference to FIG.6 and FIG.7, the effect | action of the standing-sitting assistance apparatus 100 is demonstrated.

  When assisting the standing operation of the user from the lowest position shown in FIG. 6, first, the user moves forward while sitting on the toilet seat 2 using the force of the arm placed on the handrail 40. Then, when the user or the assistant operates the operation switch while the support unit 10 supports the user's thigh, support for the user's standing operation is started. At this time, it is desirable that the center of gravity of the user is located above the support portion 10 or in front of it.

  When the operation switch is operated, a current is supplied to the electric motor 23a, and the actuator 23 is extended by the rotation of the electric motor 23a. When the actuator 23 extends, the elevating part 21 rises obliquely forward along the guide part 22. Thereby, the support part 10 raises diagonally forward, and pushes up a user's thigh. Therefore, it is possible to support the user's standing operation. At this time, the user can perform the standing motion with a small leg strength as compared with the case where the standing motion is performed only with his / her own leg strength.

  Further, the first link 25 moves the second link 26 forward along the linear guide 26c with a delay from the operation of raising the support portion 10. Accordingly, the rear end portion 26 a of the second link 26 approaches the front end portion 27 b of the third link 27, and the rear end portion 27 a of the third link 27 approaches the front end portion 26 b of the second link 26. Therefore, the handrail 40 rises with a delay from the operation of raising the support portion 10.

  Thus, since the handrail 40 rises with a delay from the support portion 10, the handrail 40 starts to rise after the weight of the user is supported by the support portion 10 to some extent after the support portion 10 starts to rise. Therefore, after grasping that the support unit 10 has started to rise, the user can prepare to perform the standing-up operation by placing a hand on the handrail 40. In this way, the user can perform a standing motion in a stable posture while placing a hand on the handrail 40.

  Then, as shown in FIG. 7, when the support portion 10 moves to the highest position, the sensor detects it, and the supply of current to the electric motor 23 a of the actuator 23 is stopped. Therefore, the actuator 23 does not extend even if the support portion 10 is further raised by operating the operation switch.

  On the other hand, when assisting the user's sitting operation from the highest position shown in FIG. 7, the user leans against the support portion 10 so that the support portion 10 supports the thigh. Then, when the user or the assistant operates the operation switch, support for the user's sitting motion is started.

  When the operation switch is operated, a current is supplied to the electric motor 23a, and the actuator 23 contracts due to the rotation of the electric motor 23a. When the actuator 23 contracts, the elevating part 21 descends obliquely rearward along the guide part 22. Thereby, the support part 10 descends obliquely rearward and gradually approaches the toilet seat 2 while supporting the user's thigh. Therefore, it is possible to support the user's sitting operation. At this time, the user can perform the sitting operation with a small leg force as compared with the case where the user performs the sitting operation only with his / her own leg force.

  Further, when assisting the user's sitting operation, the handrail 40 starts to descend simultaneously with the support unit 10. Therefore, the user can sit on the toilet seat 2 in a stable posture while placing a hand on the handrail 40.

  Then, as shown in FIG. 6, when the support portion 10 moves to the lowest position and the handrail 40 comes into contact with the stopper member 34, the sensor detects it and supplies current to the electric motor 23 a of the actuator 23. Is stopped. Therefore, even if the support portion 10 is further lowered by operating the operation switch, the actuator 23 does not contract.

  As described above, in the standing seating support device 100, the support portion 10 that supports the user's thigh is provided in front of the toilet seat 2. Moreover, the support part 10 is separated forward from the toilet seat 2 as it rises. Therefore, the toilet seat 2 itself does not operate during operation, and the support portion 10 does not interfere with the toilet seat 2 during operation. Therefore, the user's standing operation and seating operation can be supported without changing the toilet seat 2 on which the user sits.

  Further, the standing / sitting support device 100 has a simple configuration as described above, and thus is relatively compact. Therefore, it can be installed in a small space such as a toilet. The standing / sitting support device 100 can be used only by being installed on the side of an existing chair or the toilet seat 2. For this reason, it is not necessary to make a major repair in order to install the standing seating support apparatus 100.

  The standing / sitting support device 100 supports the user's thigh by the support unit 10. Therefore, since it does not support the user's buttocks, the user can raise and lower clothes himself.

  Next, with reference to FIGS. 8 to 10, the storing operation of the support portion 10 in the standing seating support apparatus 100 will be described.

  As shown in FIG. 8, the support portion 10 can be stowed up to the side of the toilet seat 2 and stored. Thereby, when the support by the standing seating assistance apparatus 100 is unnecessary, the support part 10 can be kept away from the toilet seat 2, and a sanitary state can be maintained.

  Moreover, you may store the support part 10 further from the state shown in FIG. 8 as shown in FIG.9 and FIG.10. As shown in FIG. 9, the support portion 10 is stored by being rotated so that the contact surface 11 faces the front-rear direction from the state of being flipped up to the side of the toilet seat 2. Therefore, even if the support unit 10 falls from the raised state and returns to the original state, the support unit 10 is not positioned in front of the toilet seat 2.

  Then, as shown in FIG. 10, the support portion 10 is accommodated by rotating downward from the state shown in FIG. 9 with the contact surface 11 facing the front-rear direction. Thereby, the support part 10 is accommodated so as not to protrude above the toilet seat 2. Therefore, the support part 10 can be stored in a position that does not interfere with the user.

  According to the above embodiment, there exist the effects shown below.

  In the standing seating support device 100, a support portion 10 that supports the user's thigh is provided in front of the toilet seat 2. Moreover, the support part 10 is separated forward from the toilet seat 2 as it rises. Therefore, the toilet seat 2 itself does not operate during operation, and the support portion 10 does not interfere with the toilet seat 2 during operation. Therefore, the user's standing operation and seating operation can be supported without changing the toilet seat 2 on which the user sits.

And an elevating mechanism 20 that elevates and lowers the support portion 10 so as to move forward from the toilet seat 2 as it rises.

  In this configuration, a support portion 10 that supports the user's thigh is provided in front of the toilet seat 2. Moreover, the support part 10 is separated forward from the toilet seat 2 as it rises. Therefore, the toilet seat 2 itself does not operate during operation, and the support portion 10 does not interfere with the toilet seat 2 during operation. Therefore, the user's standing operation and seating operation can be supported without changing the toilet seat 2 on which the user sits.

  Moreover, in this embodiment, it is further provided with the flame | frame 30 attached to an installation surface, and the handrail 40 which raises / lowers with respect to the flame | frame 30 which supports a user's arm, and the support part 10 and the handrail 40 are raising / lowering mechanisms. 20 is moved up and down in conjunction with each other.
