FIG. 1 is a schematic view illustrating a toilet room in which a handrail device according to an embodiment of the invention is installed.
FIG. 2 is a schematic view of the handrail device as viewed from above.

  A sitting toilet 600 is installed in the toilet room. And the handrail apparatus 10 of this embodiment is provided in the front of the seat toilet 600. FIG. The handrail device 10 includes a body holding unit 100 and an arm unit 200 that supports the body holding unit 100. In the case of the specific example shown in FIG. 1, the arm unit 200 is attached to a vertical handrail 300 attached to the wall surface 802 of the toilet room. The body holding portion 100 is supported so as to be rotatable with respect to the arm portion 200 about a rotation shaft 100C in a substantially vertical direction, as represented by an arrow R in FIG.

  The rotation shaft 100 </ b> C is provided at the approximate center of the body holding unit 100. Here, “substantially central” means that the rotating shaft 100 </ b> C is between the user's hands when the user puts both hands on the body holding unit 100. Therefore, the rotation shaft 100C does not need to be provided at the exact center of the body holding unit 100.

FIG. 3 is a schematic view illustrating the usage pattern of the handrail device of this embodiment.
The user 900 can change the direction of the body by moving in the direction of the arrow R about the rotation shaft 100 </ b> C while holding both hands on the body holding unit 100 of the handrail device 10 and holding the standing position. it can. Until the user 900 changes the orientation of the body, the same posture can always be maintained with respect to the body holding unit 100, and the orientation of the body can be changed while stably holding the standing position. Therefore, for example, when a user 900 on a wheelchair enters the toilet room so as to face the sitting toilet 600 and transfers to the sitting toilet 600 from the wheelchair, the body holding unit 100 of the handrail device 10 can stably stand up. While holding, it is possible to transfer to the sitting toilet 600 by reversing the direction of the body with a small moving distance.

FIG. 4 is a schematic view illustrating a handrail device of a comparative example.
FIG. 5 is a schematic view illustrating the usage mode of the handrail device of this comparative example.
In the case of this comparative example, a vertical handrail 300 and a horizontal handrail 400 connected thereto are attached to the wall surface 802 of the toilet room. For example, when the user 900 on the wheelchair 910 uses the handrail device to transfer from the wheelchair 910 to the sitting toilet 600, first, the wheelchair 910 is brought close to the front of the sitting toilet 600. Then, the user 900 gets his feet down from the wheelchair 910 to the floor of the toilet room, twists the upper body diagonally, grasps the horizontal handrail 400 with both hands, and stands up. After that, while holding on to the handrail 400, step over both feet to reverse the direction of the body. At this time, the upper body is twisted to the opposite side. After that, sit down on the sitting toilet 600 while holding it on the handrail 400.

  In the case of the comparative example described above, when the user 900 transfers from the wheelchair 910 to the sitting toilet 600, the user 900 sequentially switches both legs while holding the horizontal handrail 400 or the vertical handrail 300 with both hands, The direction of the body is reversed by twisting from one side (right side in the specific example shown in FIG. 5) to the other side (left side in the specific example shown in FIG. 5).

FIG. 6 is a schematic view illustrating the handrail device of the second comparative example.
The handrail device of this comparative example includes a body holding unit 100 and an arm unit 200 that supports the body holding unit 100. The arm part 200 is attached to the vertical handrail 300 attached to the wall surface 802 of the toilet room. And the body holding part 100 can turn with respect to the arm part 200 centering | focusing on the rotating shaft 100C provided in the edge part of the body holding part 100, as represented by the arrow R in Fig.6 (a). It is supported.

Even with the handrail device of this comparative example, the body can rotate. For example, in the state shown in FIG. 6A, a user who has been in a wheelchair approaches the handrail device from below in the drawing, puts both hands on the body holding unit 100, gets off the wheelchair, and stands up. Then, the body holding unit 100 is gradually moved with both hands until the state shown in FIG. 6A to FIG. 6B is reached. After moving to the state shown in FIG. 6 (b), the user sits on the sitting toilet 600 from an oblique direction with both hands on the body holding unit 100. Thereafter, the user sits down on the sitting toilet 600 and turns his body to the front.
However, in the case of the comparative example described with reference to FIGS. 4 to 6, there is room for improvement in that the movement distance of the user's body is large and the balance is easily lost.

FIG. 7 is a schematic view illustrating the relationship between the posture of the user and the position of the center of gravity of the body.
FIG. 7A shows a state where the upper body of the user is almost upright. In such a state, as shown in FIG. 7B, the center of gravity 900G of the body is within the range of the support base surface 900S. Here, the support base surface refers to a range defined by a straight line connecting both feet 904 of the user 900. When the center of gravity 900G is within the range of the support base surface 900S, the body of the user 900 can stably hold a standing position.

  On the other hand, FIG.7 (c) represents the state which the upper body of the user 900 inclined forward. In such a state, as shown in FIG. 7D, the center of gravity 900G of the body may come out of the support base surface 900S. Thus, when the center of gravity 900G exceeds the range of the support base surface 900S, the body of the user 900 becomes unstable and easily falls.

  In the case of the handrail device of the comparative example described above with reference to FIGS. 4 and 5, the user 900 grasps the horizontal handrail 400 with both hands, inclines the upper body forward, and changes the body by stepping on both legs while twisting diagonally. Must be reversed. In such a transfer operation, as illustrated in FIGS. 7C and 7D, the center of gravity 900G of the user 900 may exceed the support base surface 900S. By grasping to 400, it was possible to transfer.

  In the case of the handrail device of the second comparative example described above with reference to FIG. 6, the moving distance of the user who has both hands on the body holding unit 100 is long. That is, since the moving distance of the center of gravity is long, there is a high possibility that the center of gravity of the user's body exceeds the support base surface, as illustrated in FIGS. 7C and 7D. In the case of the handrail device of the second comparative example described above with reference to FIG. 6, when transferring from the sitting toilet 600 to the wheelchair, both hands are attached to the body holding unit 100 in the state shown in FIG. It is necessary to return to the state shown in (a). At this time, the user does not have to move backward, it is difficult to move, and the user is likely to be unstable, and his / her feet are also liable to crawl.

On the other hand, according to the handrail device of the present embodiment, the user 900 can safely change the direction of the body with a small movement distance while maintaining the body in a more stable state.
8 to 11 are schematic views illustrating usage modes of the handrail device of this embodiment.
When the user 900 riding on the wheelchair 910 uses the handrail device 10 to transfer from the wheelchair 910 to the sitting toilet 600, the user moves the wheelchair 910 to the front of the sitting toilet 600 as shown in FIG. Then, the user 900 lowers his / her feet from the wheelchair 910 to the floor of the toilet room, and stands up with both hands on the body holding unit 100 as shown in FIG. Thereafter, with both hands held on the body holding unit 100 and holding the standing position, both feet are switched, and as shown in FIGS. 9B and 9C, the direction of the arrow R around the rotation shaft 100C. Move to.

  At this time, as illustrated in FIG. 10, the user 900 can also hold the standing position with both hands on the body holding unit 100, and as illustrated in FIG. 11, With respect to 100, the standing position can be held with the forearm attached. In any of these cases, the user 900 places the front surface of the body (around the abdomen) against the body holding unit 100 and holds the standing position in an easy state leaning slightly against the body holding unit 100. It is also possible.

In this way, the user 900 can easily reverse the direction of the body by sequentially switching both feet while holding the standing position easily. When the body is inverted as shown in FIG. 9C, the user can sit comfortably on the sitting toilet 600 with both hands on the body holding unit 100 and the body stabilized.
Further, when transferring from the sitting toilet 600 to the wheelchair 910, it is possible to transfer safely and easily by executing the same steps using the handrail device 10.

  According to this embodiment, during the series of operations shown in FIGS. 9A to 9C, the center of gravity 900G of the body of the user 900 is always supported as described above with reference to FIGS. 7A and 7B. A state close to the range of the base surface 900S can be maintained. That is, the user's 900 body can maintain the state where the standing position was stably held. At the same time, the user 900 can invert the body by simply stepping both feet around the rotation axis 100C of the body holding unit 100, and does not have to take an unstable posture by twisting the body left and right. . Further, it is not necessary to move backward as in the second comparative example described above with reference to FIG. That means less physical burden. Further, since the movement of a short distance about the rotation shaft 100C is sufficient, the movement distance of the user 900 is small, and the body direction can be changed safely and easily in a short time.

  As described above, according to the present embodiment, the user can change the direction of the body safely and easily with a short posture and a stable posture. As a result, it is possible to transfer between a wheelchair and a sitting toilet or between various other facilities.

  Here, a predetermined resistance may be provided for the rotational movement of the body holding unit 100. That is, if the resistance to the rotation of the body holding unit 100 is extremely small, when the user 900 tries to hold the body holding unit 100 with one hand or both hands, the body holding unit 100 rotates unexpectedly. In addition, the user 900 may lose the balance of the body. In such a case, it is effective to provide a lock mechanism and a stopper mechanism, which will be described in detail later, but in addition to or in addition to these, for example, a brake or a By appropriately applying resistance by means of resistance applying means using a clutch called an oil damper, an ER fluid clutch, etc., the body holding unit 100 is prevented from rotating unexpectedly, and the user 900 puts weight more stably. It becomes possible. Here, the ER fluid clutch fills an ER (Electro Rheological) fluid (electrorheological fluid) whose apparent viscosity changes when a voltage is applied between the input shaft and the output shaft, and changes the applied voltage. This is a clutch in which the transmission torque is variable by controlling the fixed state of ER fluid particles.

By the way, in the specific example illustrated in FIG. 8, the rotation shaft 100 </ b> C of the body holding unit 100 is provided at a position substantially coincident with the center line 600 </ b> L of the sitting toilet 600. However, the present invention is not limited to this.
12 and 13 are schematic views illustrating the positional relationship between the body holding unit 100 and the sitting toilet 600. FIG.
In the case of the specific example shown in FIG. 12, the rotation shaft 100 </ b> C of the body holding unit 100 is provided on the center line 100 </ b> L in the width direction of the body holding unit 100. Then, the rotation shaft 100 </ b> C is displaced from the center line 600 </ b> L of the sitting toilet 600 in the direction of the wall surface 802 to which the arm unit 200 is fixed. In this way, for example, when the user 900 reverses the body direction with the handrail device 10 in a narrow toilet room, it is possible to prevent the back of the user 900 from interfering with the wall surface 804 facing the wall surface 802. Further, when the user 900 reverses his / her body, the user 900 can move around the center line 600 </ b> L of the sitting toilet 600 to transfer with a shorter moving distance.

  In the specific example shown in FIG. 13, the center line 100 </ b> L in the width direction of the body holding unit 100 and the center line 600 </ b> L of the sitting toilet 600 do not match. However, the rotation axis 100C of the body holding unit 100 is not on the center line 100L, but is shifted from the center line 600L of the sitting toilet 600 in the direction of the wall surface 802 to which the arm unit 200 is fixed.

  Even in this case, similarly to the specific example described above with reference to FIG. 12, it is possible to prevent the back of the user 900 from interfering with the wall surface 804 in a narrow toilet room. It is possible to transfer.

FIG. 14 is a schematic diagram illustrating a specific example of the handrail device of the present embodiment.
The handrail device 10 of this specific example also includes a body holding unit 100 and an arm unit 200.

In this way, when the handrail device 10 is not used, it does not get in the way, and the handrail device 10 can be used or stored by simply moving the body holding unit 100 up and down. is there.

  The connecting portion 220 may be rotatable about a substantially vertical rotation axis. In this way, instead of flipping the body holding part 100 upward, the body holding part 100 and the arm part 200 are brought closer to the wall surface by turning in the horizontal plane around the turning axis of the connecting part 220. The storage state can be established. In this case, a lock mechanism may be appropriately provided so that the connecting portion 220 does not rotate during use.

  On the other hand, the height of the handrail device 10 can be adjusted by making it possible to change the mounting position of the fixing portion 210 with respect to the vertical handrail 300. For example, a locking mechanism is provided in the fixing portion 210 so that the fixing portion 210 can be moved in the vertical direction with respect to the vertical handrail 300 in the unlocked state. When the height of the fixing portion 210 is determined, the fixing portion 210 is fixed to the vertical handrail 300 by locking. If it does in this way, the height of the handrail apparatus 10 can be adjusted with the size of the installation which installs the handrail apparatus 10, the physique of the user 900, etc.

FIG. 15 is a schematic diagram illustrating another specific example of the handrail device of the present embodiment.

  In this specific example, the connecting portion 220 is provided with a bracket 222 and a hook 224. As shown in FIGS. 16A and 17A, the hook 224 is in a released state when the body holding unit 100 is lowered. On the other hand, when the body holding unit 100 is flipped upward as shown in FIGS. 16B and 17B, the hook 224 engages with the bracket 222 and is locked. That is, the body holding unit 100 can hold the state of being flipped up and stored. When the handrail device 10 is used, the hook 224 is lifted to release the engagement with the bracket 222, and the body holding unit 100 is lowered.

FIG. 18 is a schematic diagram illustrating still another specific example of the handrail device of the present embodiment.
Also in this specific example, the handrail device 10 is directly attached to the wall surface 802. And the height of the body holding | maintenance part 100 can be adjusted by making the connection part 220 and the rotation support part 240 cooperate. For example, the connecting part 220 can be rotated around a substantially horizontal rotation axis. On the other hand, the rotation support unit 240 supports the body holding unit 100 so as to be rotatable about a substantially vertical axis, and can support the body holding unit 100 also about a substantially horizontal rotation axis. When adjusting the height of the body holding part 100, the connecting part 220 is appropriately rotated, and the rotation support part 240 is appropriately rotated around a substantially horizontal rotation axis. In this way, the height of the body holding unit 100 can be adjusted without changing the posture of the body holding unit 100 as illustrated by the broken line in FIG. Note that after the height is adjusted, the rotation shaft of the connecting portion 220 and the substantially horizontal rotation shaft of the rotation support portion 240 may be appropriately locked.

FIG. 19 is a schematic diagram illustrating still another specific example of the handrail device of the present embodiment.
In this specific example, a lock mechanism that prevents the body holding unit 100 from rotating is provided. That is, the flange 244 is attached to the rotation support part 240. The flange 244 does not rotate in the rotation direction of the body holding unit 100, and maintains the state of being fixed relative to the arm unit 200 even when the body holding unit 100 rotates. On the other hand, the body holding unit 100 is provided with a lever 110 that can be tilted around the fulcrum 112. A push button 114 is provided at the distal end of the lever 110 on the outer peripheral side, and a lock pin 118 appropriately biased by a biasing means 116 such as a spring is provided at the distal end on the inner peripheral side of the lever 110.
