It is not intended and is equally applicable to the mobility aids of other embodiments within the scope of the claims.

<First Embodiment>
1 to 6 are a perspective view, a front view, a rear view, a right side view, a plan view, and a bottom view, respectively, showing the appearance of the movement assisting tool of the present embodiment. In the following description of FIGS. 1 to 6, the upper side of the observer facing the page of FIG. 3 is “upper”, the lower side is “lower”, the left hand side is “left”, and the right hand side is “right”. In the following description, the upper side of the observer facing the paper surface of FIG. 5 is “rear” and the lower side is “front”.

  In the present embodiment, the movement assisting tool 100 is provided on the base frame 2, the foot plate 3 provided on the base frame 2, the two wheel parts 4 provided on the rear part of the base frame 2, and provided on the front part of the base frame 2. A wheel portion 6 having a mechanism 5, two struts 7 erected on the base frame 2, a knee fixture 8 provided near the center of the strut 7 to support the knee of a person requiring assistance, and an upper portion of the strut 7 A torso fixture 9 (which is also referred to as a body fixture in the present specification and claims), and the upper end of the support column 7. A top plate 10 is provided. 1 to 6, for simplification of the drawings, reference numerals 2 (base frame), 8 (knee fixing tool), and 9 (torso fixing tool) are not shown, and each component is configured (for example, knee fixing tool). 8, reference numerals 81 (knee support portions) and 82 (side panels) are indicated by reference numerals.

  The base frame 2 includes two side frames 21 and two side frames 21 arranged substantially in parallel at a predetermined interval, a generally square front frame 22 that connects two side frames 21 at the front portion thereof, and left and right sides. The frame 21 is connected to the left and right support columns 7 to have two connection frames 23 for distributing the force applied to the support columns 7.

  The side frame 21 is substantially parallel to the floor surface on which the movement assisting tool 100 is placed from the rear end portion to the center portion (substantially parallel to a straight line connecting the lower end portion of the wheel portion 4 and the lower end portion of the wheel portion 6 in a side view). extend. The side frame 21 is formed in a shape that bends upward with respect to the rear portion from the center portion to the front end portion. With this configuration, when storing a plurality of movement assisting tools 100, the rear part of the side frame 21 of one continuous movement assisting tool 100 is made to sink under the front part of the side frame 21 of the other movement assisting tool 100. Therefore, the storage space can be used effectively.

  A bent portion 21a is formed at the rear end portion of the side frame 21 so as to bend outwardly in plan view, and a non-slip cap is attached to the bent portion 21a. Thereby, when the movement assistance tool 100 inclines back, the bending part 21a can contact a floor surface and can prevent the movement assistance tool 100 from falling backward. Therefore, the bent portion 21a can be rephrased as the fall prevention frame 21a. In addition, in this embodiment, the bending part 21a is comprised so that a floor surface may be contacted when the movement assistance tool 100 inclines back about 4 degree | times. This is because, when the body of the person requiring assistance is not fixed by the body fixing tool, the risk that the person requiring assistance falls over backwards when the movement assistance tool is tilted rearward exceeding 5 degrees is increased.

  Further, when the bent portion 21a is formed in a letter C shape in a plan view (a state in which the separation distance between the rear ends of the two side frames 21 is wide), the foot plate 3 is brought into close contact with the toilet bowl. A lower part contacts the bending part 21a and guides the movement assistance tool 100 to the front of the toilet bowl. Thereby, the position of the movement assistance tool 100 can be guided to a position where the transfer of the person requiring assistance between the toilet and the movement assistance tool 100 can be performed safely and smoothly.

  In addition, you may provide the bending part 21a so that rotation of 180 degree | times is possible. That is, in this embodiment, the bent portions 21a of the two side frames 21 are formed in a C shape in plan view, but are reversely H-shaped (the separation distance between the rear ends of the two side frames 21 is narrow). The state may be deformable. With this configuration, when the wheelchair is brought close to the movement assisting tool 100, the side frame 21 can be inserted into the space between the wheel portions of the wheelchair so that the distance between the wheelchair and the foot plate 3 can be reduced. Therefore, transfer of a person requiring assistance between the wheelchair and the movement assisting tool 100 can be performed safely and smoothly.

  The front frame 22 is formed in a substantially square shape that spreads forward in plan view. With this configuration, the movement assisting tool 100 can be brought closer to the male urinal compared to when the front frame 22 is linear, and a person requiring assistance can use the apparatus while being placed on the movement assisting apparatus 100. it can. Note that the shape of the front frame 22 is not limited to a substantially square shape, and the front frame 22 collides with the front of the urinal body when the distance between the person requiring assistance and the urinal is too long. Any shape that avoids this (for example, a substantially U shape) may be used.

  The foot plate 3 is a step on which a person requiring assistance rests in a standing position. The foot plate 3 is detachably provided across the two side frames 21. The front end of the foot plate 3 is located in front of the support column 7 to be described later, and the toe of the leg fixed when one leg of the person requiring assistance is placed on the foot plate 3 and fixed by the body fixing device is in front of the support column 7. Can be placed on the foot plate 3.

  Further, the rear end of the foot plate 3 is located in the vicinity of the middle between the rear end of the side frame 21 and the substantially central portion of the side frame 21 on which the column 7 is erected (that is, the rear end of the foot plate 3 has two ends). A space S1 in which the foot plate 3 is not disposed is provided between the rear portions of the side frames 21 and the rear portions of the side frames 21). In other words, the space S1 is behind the foot plate 3 and is not fixed in a state where one leg of a person requiring assistance is placed on the foot plate 3 and fixed by a body fixing tool, and the body is left on the top plate 10. The other leg is formed in a range reaching the floor surface.

  The rear side of the foot plate 3 is a position where the other leg naturally moves when the upper body is swung over the top plate with one leg fixed, and a space S1 is formed behind the foot plate 3. This makes it easier for the person who needs help to kick the floor.

  In this embodiment, the foot plate 3 is detachably provided along the shape of the side frame 21, but the inclination angle of the foot plate 3 may be adjusted and detachable with respect to the side frame 21. The method for adjusting the tilt angle is not particularly limited, but for example, a mechanism capable of adjusting the vertical position of the front end of the foot plate 3 may be provided. By moving the front end of the foot plate 3 up, the movement assisting tool 100 can be used as an ankle joint training standing board (a device for correcting the cusps due to the weight of the foot during a long-term illness). In addition, by lowering the front end of the foot plate 3, the center of gravity of the person who needs assistance on the foot plate 3 naturally moves forward, making it easier to deposit weight on the top board 10, and preventing falling back more reliably. can do.

  The wheel unit 4 is a smaller wheel than the wheel unit 6. Since the wheel part 4 is a small wheel, the rear part of the side frame 21 can be inserted into the gap between the bed and the floor surface when the movement assisting tool 100 is brought close to the low floor bed. Transfer can be performed smoothly. The wheel unit 4 is preferably separated from the support column 7 in a side view from the viewpoint of safety against the backward movement of the movement assisting tool 100, and in a side view from the viewpoint of ease of changing the direction of the movement assisting tool 100. It is desirable to be close to the position of the center of gravity of the person requiring assistance (the position of the column 7 or knee support 81 in the side frame 21 when the person requiring assistance falls on the top plate 10). Therefore, the position of the wheel portion 4 in the side frame 21 is determined in consideration of both.

  Specifically, when the position of the wheel portion 4 is set to the front of the leg of the person who needs assistance placed on the foot plate 3, the movement assisting tool 100 easily falls backward. Even if the movement assisting tool 100 is tilted rearward, the fall assisting frame 100a is prevented from falling by contacting the floor surface. However, if the movement assisting tool 100 swings up and down around the person requiring assistance, Running performance is deteriorated and safety is also impaired. As described above, in the movement assisting tool 100 of this embodiment, the toe of the person requiring assistance is placed on the foot plate 3 in front of the column 7. Accordingly, the position of the wheel portion 4 is determined based on the length of the sole from the base of the toes to the heel except for the toes.

  The length of the sole from the toes of the adult to the heel is about 22 cm to 30 cm, and when the mobility aid 100 is manufactured for an adult, the wheel is based on the adult with the largest foot from the viewpoint of safety. It is desirable to determine the position of the part 4. The average length of the sole from the base of the toe to the heel of a person having a foot size of 30 cm is about 23 cm. Therefore, by setting the position of the wheel part 4 to be a position spaced about 23 cm rearward from the support column 7 or the knee support part 81 in the side frame 21, it is possible to realize the ease of direction change while considering safety.

  Further, as shown in the present embodiment, the movement assisting tool 100 is rearward when the person requiring assistance stands at the rear end portion of the foot plate 3 by setting the position of the wheel portion 4 behind the rear end of the foot plate 3. Can be prevented from becoming unstable.

  A wheel larger than the wheel unit 4 is attached to the wheel unit 6 in order to improve the stability and traveling performance of the movement assisting tool 100 and because the front part of the side frame 21 is bent upward. By using at least one of the wheel part 4 or the wheel part 6 as a free caster (turning caster), the traveling direction of the movement assisting tool 100 can be easily adjusted. Desirably, as shown in this embodiment, the wheel portion 6 may be a free caster, and the wheel portion 4 may be a fixed caster (a caster that does not turn).

  At this time, the wheel portion 4 may be attached to the inside of the side frame 21, but it is desirable that the wheel portion 4 is attached so as not to be able to turn with respect to a horizontal axis extending in the left-right direction from the side frame 21 as shown in each drawing. With this configuration, the distance between the two wheel portions 4 is widened, and the wheel portion 4 has a maximum diameter that can be inserted between the low floor bed and the floor surface. it can. By increasing the separation distance between the two wheel portions 4 and maximizing the diameter of the wheel portions 4 as much as possible, the stability and travelability of the movement aid 100 are improved.

  In the case where the wheel unit 4 is a free caster, if the rotation of the wheel unit 4 is not locked after the wheel unit 4 is inserted into the gap between the low floor bed and the floor surface, the movement assisting tool 100 slides when the person requiring assistance moves. Although there is a risk, it is difficult to lock the wheel part 4 after inserting the wheel part 4. On the other hand, by using the wheel part 4 as a fixed caster as in this embodiment, it is difficult for the wheel part 4 to slide sideways without being locked after the wheel part 4 is inserted into the gap between the low floor bed and the floor surface. Safety at the time can be ensured.

  The wheel portion 6 is attached so as to be able to turn with respect to a vertical axis extending in the vertical direction from the front frame 22. The wheel portion 6 is also preferably separated from the support column 7 in a side view from the viewpoint of safety against the forward fall of the movement assisting tool 100, similarly to the wheel portion 4. From the viewpoint, it is desirable that the position is close to the position of the center of gravity (support 7 or knee support 81) of the person requiring assistance in a side view. In particular, when a person requiring assistance deposits his / her weight on the top board 10, a force is applied in the direction in which the movement assisting tool 100 falls forward, and movement in the forward direction can be faster than movement in the backward direction. When a collision with a step or the like on the floor surface is strong and a strong force is applied in the direction in which the movement assisting tool 100 rotates forward around the wheel portion 6, the position of the wheel portion 6 in the side frame 21 is the wheel portion. It is necessary to consider the former more importantly than 4.

  The position of the wheel portion 6 is determined according to the height of the support column 7, and if the height of the support column 7 is increased, the separation distance between the wheel unit 6 and the support column 7 is increased. In the present embodiment, the height of the support column 7 is set to a height at which a person requiring assistance can be comfortably drowned on the top plate 10 provided at the upper end of the support column 7, for example, about 110 cm. In this configuration, the separation distance between the support column 7 and the wheel portion 6 is desirably 20 cm or more, and more desirably 30 cm or more. In this embodiment, the separation distance between the support column 7 and the wheel portion 6 is made longer than the separation distance between the support column 7 and the wheel portion 4 to prevent the movement assisting tool 100 from tipping forward, and the movement assist with higher stability. The tool 100 is used.

  The lock mechanism 5 prevents a wheel assistant 6 from turning or rotating when a person requiring assistance moves from the movement assisting tool 100 or moves to the movement assisting tool 100 so that the movement assisting tool 100 does not move. It is intended to ensure the safety of those who require assistance during transfer. Further, as described above, when the person requiring assistance uses a urinal, the movement assisting tool 100 can be maintained in an immobile state by the lock mechanism 5. At least the free caster is provided with the lock mechanism, and in this embodiment, the wheel portion 6 which is a free caster is provided with the lock mechanism 5, but when the wheel portion 4 is a free caster, the wheel portion 4 is provided with a lock mechanism. In addition, even if it is a fixed caster, it is good also as providing a locking mechanism.

  The column 7 is erected upward from a substantially central portion of the side frame 21. A knee fixing device 8 is provided at a substantially central portion in the vertical direction of the support column 7. The knee fixing device 8 includes a knee receiving portion 81 that receives the kneecap of the person requiring assistance and two side panels 82 that prevent the knee of the person requiring assistance from shifting in the left-right direction. The torso of the person requiring assistance is fixed by a torso fixing tool 9 described later, so that the kneecap of the person requiring assistance is pressed against the knee receiving part 81.

  A trunk fixture 9 is provided on the upper portion of the column 7. The trunk | drum fixing tool 9 has the abdominal part receiving part 91 which receives the abdomen of a helper. With the abdomen of the person requiring assistance pressed against the abdomen receiving part 91, the torso of the person requiring assistance is fixed to the abdomen receiving part 91 by pressing the abdomen from the lumbar side toward the abdomen receiving part 91 with a belt (not shown). Is done.

  In order to maintain the standing position of a person who needs assistance who is difficult to maintain the standing position by himself / herself, it is only necessary to support the sole, knee, and torso. In this embodiment, the sole is pressed against the foot plate 3 by the self-weight of the person requiring assistance by placing the person on the foot plate 3 on the sole. As described above, the torso of the person requiring assistance is fixed to the abdomen receiving part 91 by pressing the abdomen toward the abdomen receiving part 91 with a belt (not shown). As described above, the knee is pressed against the knee support 81 by fixing the torso of the person requiring assistance to the abdomen support 91. By such three-point support, it is possible to maintain the standing position of a person who needs assistance, which is difficult to maintain the standing position by himself.

  A top plate 10 is provided at the upper end of the column 7. The top plate 10 is a flat plate, and of the side walls, the side wall that is contacted by a person requiring assistance is formed in a shape that is recessed forward. With this configuration, as described above, when a person requiring assistance uses the urinal while being placed on the movement assisting tool 100, the body of the person requiring assistance can be brought closer to the urinal. The top plate 10 is provided on the column 7 in a state where it is inclined about 5 degrees toward the rear (toward the person requiring assistance) with respect to the rear portion of the foot plate 3. With this configuration, it is possible to correct the posture by setting the standing posture of the person in need of assistance when the person in need falls to the top board 10 as the correct standing posture.

  The top plate 10 may be provided so that the height and the inclination angle can be adjusted. The structure capable of adjusting the height of the top plate 10 with respect to the foot plate 3 is not particularly limited. For example, the bottom plate of the top plate 10 has a height adjustment shaft that can be inserted into the support column 7 and is locked at an arbitrary height. Alternatively, the height of the top plate 10 may be adjusted by locking at any height among a plurality of heights provided in stages. The structure capable of adjusting the inclination angle of the top plate 10 with respect to the foot plate 3 is not particularly limited. For example, the support column 7 includes a fixed plate at the upper end, and the top plate 10 is attached to the fixed plate via a support arm. The inclination angle of the top plate 10 may be adjusted by attaching to the fixed plate and making it possible to change the support position of the top plate 10 by the support arm.

  By making the height of the top plate 10 adjustable, the height of the top plate 10 can be set to an appropriate position according to the height and physique of the person requiring assistance. Moreover, by making the angle of the top plate 10 adjustable, the angle of the top plate can be set to an appropriate inclination angle depending on the application.

<How to use>
Hereinafter, the usage method of the movement assistance tool 100 of this embodiment is demonstrated. In this embodiment and the following embodiments, one leg (left leg in this example) is inconvenient and difficult to stand on its own, but the other leg (originally the right leg) needs to move relatively. A person who needs assistance, A person who needs assistance who is difficult to stand on his or her own legs, and B who needs assistance, B who is difficult to walk on his own, but who needs to move both legs relatively, needs assistance C Will be described.

  Although it is difficult for the person A requiring assistance to maintain the standing position by himself, the right leg moves relatively, so the left leg, which is a non-free leg, is placed on the foot plate 3 with the sole of the left leg placed on the foot plate 3. The knee is pressed against the knee receiving part 81 and the torso is fixed to the abdominal receiving part 91. Thereby, the standing position of the person A requiring assistance is maintained. Since the right leg can be freely moved in this state, the sole of the right leg can be brought into contact with the floor through the space S1 provided behind the foot plate 8. And the wheel part 4 and the wheel part 6 rotate by kicking a floor surface using a right leg, and the movement assistance tool 100 can be moved to a desired direction with the intention of the assistance person A required. Helper A can lean on the top plate with both hands and upper body, so that the weight of the upper body can be deposited on the top plate, and the wheel that is a free caster by changing the position of the body's center of gravity by changing the position of drowning The direction in which the part 6 turns and the movement assisting tool 100 advances can be set as a desired direction.

  Since the person who needs assistance B is incapable of both legs, he / she cannot drive the movement assisting tool 100 by himself / herself. Therefore, the knees of both legs are supported by the knee receiving portion 81 while the soles of both legs are placed on the foot plate 3, and the torso is fixed by the abdominal portion receiving portion 91. Thereby, the standing position of the person B who needs assistance is maintained. After confirming that the standing position of the person B requiring assistance is maintained, the assistant pushes or pulls the movement assisting tool 100 to apply a force in the horizontal direction to turn the wheel portion 6, The person B who needs assistance can be moved by rotating the wheel part 4 and the wheel part 6.

  The helper C can move both legs relatively and can stand by himself / herself. Therefore, the movement assistance tool 100 can be used like a walker by removing the foot plate 3 from the base frame 2. The person in need of assistance C can move by turning the wheel portion 6 while walking and rotating the wheel portion 4 and the wheel portion 6.

  According to the present embodiment, of the wheel portions provided before and after the base frame, one wheel portion is a fixed caster and the other is a free caster. Therefore, when the person who needs assistance moves the movement aid with the standing assistance provided by the movement assistance tool, the fixed caster does not move even if the direction in which the person who needs assistance leans against the movement aid differs from the straight direction. Go straight without turning. In addition, when a person requiring assistance changes the traveling direction of the movement assisting tool to a different direction, the traveling direction can be easily changed by turning the free caster. With this configuration, it is possible to achieve both straightness and turning performance of the movement assist tool.

  Moreover, the wheel part provided in a front part is a free caster, and the wheel part provided in a rear part is a fixed caster. With this configuration, it is difficult to skid even if the wheel portion provided at the rear portion is not locked after being inserted into the gap between the low floor bed and the floor surface, so that safety at the time of transfer of the person requiring assistance can be ensured.

  Further, the position of the second wheel portion in the base frame is determined based on the position of the support or body fixing member in the base frame and the length of the sole from the base of the toe to the heel. With this configuration, it is possible to provide a movement aid that achieves both safety and ease of direction change.

  Moreover, the position of the 2nd wheel part in a base frame is located back rather than the rear end of a footplate. With this configuration, it is possible to prevent the movement assisting tool 100 from tilting backward and becoming unstable when a person requiring assistance stands at the rear end of the foot plate.

  Further, the base frame includes a fall prevention frame extending backward from a position where the second wheel portion (wheel portion 4) is attached. Therefore, even if the person requiring assistance loses balance, the center of gravity of the person requiring assistance on the foot plate moves rearward and the mobility aid tilts rearward, the fall prevention frame contacts the floor surface and beyond. Can prevent falling.

  Moreover, a top plate is provided at the upper end of the support column, and the top plate is provided to be inclined with respect to the foot plate. By tilting the top plate toward the rear (required helper), the top plate is flat (parallel to the foot plate) when the helper who maintains the standing position on the foot plate leans on the top plate. Compared to a certain case, the position of the arm or elbow is raised and the upper body is raised, so that the back muscles are stretched, and the standing posture of the person requiring assistance can be set to the correct standing posture.

  Further, the top plate is supported by the support so that the inclination angle with respect to the foot plate can be adjusted. Therefore, when setting the standing posture of the person requiring assistance to the correct standing posture, it is inclined backward as described above, and when the work is performed on the top plate, the top plate is flattened. It can be an inclination angle.

  Further, the top plate is supported by the support so that the height relative to the foot plate can be adjusted. Therefore, it can be set to an appropriate height according to the height and physique of the person requiring assistance.

  Further, the foot plate is provided on the side frame so that an inclination angle with respect to the side frame can be adjusted. Therefore, the angle of the foot plate can be set to an appropriate angle according to the use application of the movement aid (movement use, ankle joint training use, etc.).

  The base frame includes two side frames arranged at a predetermined interval and a front frame that connects the two side frames at the front portion thereof. The front frame is formed in a shape that expands forward corresponding to the shape of the front wall of the male urinal, so that the movement aid can be brought closer to the male urinal.

  In this embodiment, the movement assisting tool 200 is provided on the base frame 2, the foot plate 3 provided on the base frame 2, the two wheel parts 4 provided on the rear part of the base frame 2, and the front part of the base frame 2. A wheel portion 6 having a mechanism 5, two struts 7 erected on the base frame 2, a knee fixture 8 provided near the center of the strut 7 to support the knee of a person requiring assistance, and an upper portion of the strut 7 A torso fixture 9 (which is also referred to as a body fixture in the present specification and claims), and the upper end of the support column 7. A top plate 10 is provided. 7 to 12, reference numerals 2 (base frame), 3 (foot plate), 8 (knee fixing tool), and 9 (torso fixing tool) are not shown for the sake of simplification of the drawings, and each part is configured. Configurations (for example, the reference numeral 81 (knee support part) and 82 (side panel) for the knee fixture 8) are shown with reference numerals.

  The base frame 2 includes two side frames 21, two side frames 21, two side frames 21 arranged substantially parallel to each other at a predetermined interval, and a substantially rectangular front frame 22 connecting the front portions thereof, and left and right side frames 21. Are connected to the left and right support columns 7 to disperse the force applied to the support columns 7 and are arranged approximately in the middle of the two connection frames 23 and the two side frames 21 in parallel with the two side frames 21 and 2. The sub-frame 24 is shorter than the side frames 21, and the two connection frames 25 connect the upper and lower ends of the sub-frame 24 to the two guide frames 21.

  The side frame 21 is substantially parallel to the floor surface on which the movement assisting tool 200 is placed from the rear end portion to the center portion (substantially parallel to a straight line connecting the lower end portion of the wheel portion 4 and the lower end portion of the wheel portion 6 in a side view). extend. The side frame 21 is formed in a shape that bends upward with respect to the rear portion from the center portion to the front end portion. The subframe 24 shorter than the side frame 21 has a rear end position aligned with the rear end portion of the guide frame 21 and is substantially parallel to the floor surface on which the movement assisting tool 200 is placed from the rear end portion to the front portion (in side view). And substantially parallel to the straight line connecting the lower end portion of the wheel portion 4 and the lower end portion of the wheel portion 6) and parallel to the side frame 21 by being bent upward from the front portion to the front end portion. Arranged. When storing a plurality of movement assisting tools 200 with this configuration, the rear part of the side frame 21 of one continuous movement assisting tool 200 is placed under the side frame 21 of the other movement assisting tool 200 and the front part of the subframe 24. The storage space can be used effectively because the storage space can be stacked so as to be embedded.

  In the present embodiment, the rear end portion of the side frame 21 is linear, but may have a bent portion 21a as in the first embodiment. In this embodiment as well, the frame behind the wheel portion 4 (the rear end portion of the side frame 21) in the side frame 21 constitutes a fall prevention frame.

  The front frame 22 is formed in a substantially square shape that spreads forward in plan view. With this configuration, the movement assisting tool 200 can be brought closer to the male urinal compared to when the front frame 22 is linear, and a person requiring assistance can use the apparatus while being placed on the movement assisting tool 200. it can. Note that the shape of the front frame 22 is not limited to a substantially square shape, and the front frame 22 collides with the front of the urinal body when the distance between the person requiring assistance and the urinal is too long. Any shape that avoids this (for example, a substantially U shape) may be used.

  The foot plate 3 is a step on which a person requiring assistance rests in a standing position. The foot plate 3 includes a first plate 31 located on the left side and a second plate 32 located on the right side. The first plate 31 and the second plate 32 are rotatably connected by hinges H arranged in the front and rear directions. The foot plate 3 is detachably provided across the side frame 21 and the sub frame 24 with the hinge closed (folded so that the first plate 31 and the second plate 32 are overlapped as shown in FIG. 7). It is done. The front end of the foot plate 3 is located in front of the support column 7 to be described later, and the toe of the leg fixed when one leg of the person requiring assistance is placed on the foot plate 3 and fixed by the body fixing device is in front of the support column 7. Can be placed on the foot plate 3.

  In the present embodiment, the foot plate 3 is foldable, and the first plate 31 and the second plate 32 are both attached and detached when attaching / detaching. However, the present invention is not limited to this. The second plate 32 may be individually removable.

  By overlapping or removing one of the first plate 31 and the second plate 32 on the other plate, a space S2 is provided on the right side or the left side of the base frame 2 (between one side frame 21 and the foot plate 3). . In other words, the space S2 is on the side of the foot plate 3, and is fixed in a state where one leg of a person requiring assistance is placed on the foot plate 3 and fixed by a body fixing tool, and the body is left on the top plate 10. The other leg that does not exist is formed in a range that reaches the floor surface.

  When walking, both legs move side by side and back and forth. Even when moving the mobility aid by kicking the floor with one leg, the space for kicking the floor is provided on the side of the other leg, so that it is possible to walk To) can kick the floor naturally. Further, compared to kicking the floor surface behind the foot plate 3, the stroke becomes longer by kicking the floor surface on the side, and the movement distance of the movement assisting tool 200 per time by kicking the floor surface is longer. It can be.

  On the other hand, as shown in FIG. 13, the foot plate 3 is detachably provided across the two side frames 21 with the hinge opened.

  In this embodiment, the foot plate 3 is detachably provided along the shape of the side frame 21, but the inclination angle of the foot plate 3 may be adjusted and detachable with respect to the side frame 21. The method for adjusting the tilt angle is not particularly limited, but for example, a mechanism capable of adjusting the vertical position of the front end of the foot plate 3 may be provided. By moving up the front end of the foot plate 3, the movement assisting tool 200 can be used as an ankle joint training standing board (a device for correcting the cusps caused by the weight of the foot during long-term sickness). In addition, by lowering the front end of the foot plate 3, the center of gravity of the person who needs assistance on the foot plate 3 naturally moves forward, making it easier to deposit weight on the top board 10, and preventing falling back more reliably. can do.

  The wheel unit 4 is a smaller wheel than the wheel unit 6. Since the wheel part 4 is a small wheel, the rear part of the side frame 21 can be inserted into the gap between the bed and the floor surface when the movement assisting tool 200 is brought close to the low floor bed. Transfer can be performed smoothly. The wheel unit 4 is preferably separated from the support column 7 in a side view from the viewpoint of safety against the backward movement of the movement assisting tool 200, and in a side view from the viewpoint of ease of changing the direction of the movement assisting tool 200. It is desirable to be close to the position of the center of gravity of the person requiring assistance (the position of the column 7 or knee support 81 in the side frame 21 when the person requiring assistance falls on the top plate 10). Therefore, the position of the wheel portion 4 in the side frame 21 is determined in consideration of both.

  Specifically, when the position of the wheel unit 4 is set to the front of the leg of the person requiring assistance placed on the foot plate 3, the movement assisting tool 200 easily falls backward. Even if the movement assisting tool 200 is tilted rearward, the fall assisting frame 200a contacts the floor surface, so that the movement assisting tool 200 itself is prevented from falling, but when the movement assisting tool 200 swings up and down around the person requiring assistance. Running performance is deteriorated and safety is also impaired. As described above, in the movement assisting tool 200 of the present embodiment, the toe of the person requiring assistance is placed on the foot plate 3 in front of the column 7. Accordingly, the position of the wheel portion 4 is determined based on the length of the sole from the base of the toes to the heel except for the toes.

  The length of the sole from the toes to the heel of an adult is about 22 cm to 30 cm. When manufacturing the mobility aid 200 for an adult, the wheel is based on the adult with the largest foot from the viewpoint of safety. It is desirable to determine the position of the part 4. The average length of the sole from the base of the toe to the heel of a person having a foot size of 30 cm is about 23 cm. Therefore, by setting the position of the wheel part 4 to be a position spaced about 23 cm rearward from the support column 7 or the knee support part 81 in the side frame 21, it is possible to realize the ease of direction change while considering safety.

  A wheel larger than the wheel portion 4 is attached to the wheel portion 6 in order to improve the stability and traveling performance of the movement assisting tool 200 and because the front portion of the side frame 21 is bent upward. By making at least one of the wheel part 4 or the wheel part 6 a free caster (a turning caster), the traveling direction of the movement assisting tool 200 can be easily adjusted. Desirably, as shown in this embodiment, the wheel portion 6 may be a free caster, and the wheel portion 4 may be a fixed caster (a caster that does not turn).

  At this time, the wheel portion 4 may be attached to the inside of the side frame 21, but it is desirable that the wheel portion 4 is attached so as not to be able to turn with respect to a horizontal axis extending in the left-right direction from the side frame 21 as shown in each drawing. With this configuration, the distance between the two wheel portions 4 is widened, and the wheel portion 4 has a maximum diameter that can be inserted between the low floor bed and the floor surface. it can. By increasing the separation distance between the two wheel portions 4 and maximizing the diameter of the wheel portions 4 as much as possible, the stability and running performance of the movement aid 200 are improved.

  If the wheel unit 4 is a free caster and the wheel unit 4 is inserted into the gap between the low floor bed and the floor surface and the rotation of the wheel unit 4 is not locked, the movement assisting tool 200 slides sideways when the person requiring assistance moves. Although there is a risk, it is difficult to lock the wheel part 4 after inserting the wheel part 4. On the other hand, by using the wheel part 4 as a fixed caster as in this embodiment, it is difficult for the wheel part 4 to slide sideways without being locked after the wheel part 4 is inserted into the gap between the low floor bed and the floor surface. Safety at the time can be ensured.

  The wheel portion 6 is attached so as to be able to turn with respect to a vertical axis extending in the vertical direction from the front frame 22. The wheel portion 6 is also preferably separated from the support column 7 in a side view from the viewpoint of safety against the forward fall of the movement assisting tool 200 as in the case of the wheel portion 4, and the direction of the movement assisting tool 200 can be easily changed. From the viewpoint, it is desirable that the position is close to the position of the center of gravity (support 7 or knee support 81) of the person requiring assistance in a side view. In particular, when a person requiring assistance deposits weight on the top board 10, a force is applied in the direction in which the movement assisting tool 200 falls forward, and movement in the forward direction can be faster than movement in the backward direction. When a collision with a step or the like on the floor surface is strong, a strong force is applied in the direction in which the movement assisting tool 200 rotates forward around the wheel portion 6, so the position of the wheel portion 6 in the side frame 21 is the wheel portion. It is necessary to consider the former more importantly than 4.

  The position of the wheel portion 6 is determined according to the height of the support column 7, and if the height of the support column 7 is increased, the separation distance between the wheel unit 6 and the support column 7 is increased. In the present embodiment, the height of the support column 7 is set to a height at which a person requiring assistance can be comfortably drowned on the top plate 10 provided at the upper end of the support column 7, for example, about 110 cm. In this configuration, the separation distance between the support column 7 and the wheel portion 6 is desirably 20 cm or more, and more desirably 30 cm or more. In the present embodiment, the separation distance between the support column 7 and the wheel portion 6 is made longer than the separation distance between the support column 7 and the wheel portion 4 to prevent the movement assisting tool 200 from falling forward, and the movement assistance with higher stability is achieved. The tool 100 is used.

  The lock mechanism 5 prevents the wheel part 6 from turning or rotating when a person requiring assistance moves from the movement assisting tool 200 or moves to the movement assisting tool 200 so that the movement assisting tool 200 does not move. It is intended to ensure the safety of those who require assistance during transfer. Further, as described above, when the person requiring assistance is using a urinal, the movement assisting tool 200 can be maintained in an immobile state by the lock mechanism 5. At least the free caster is provided with the lock mechanism, and in this embodiment, the wheel portion 6 which is a free caster is provided with the lock mechanism 5, but when the wheel portion 4 is a free caster, the wheel portion 4 is provided with a lock mechanism. In addition, even if it is a fixed caster, it is good also as providing a locking mechanism.

  The column 7 is erected upward from a substantially central portion of the side frame 21. A knee fixing device 8 is provided at a substantially central portion in the vertical direction of the support column 7. The knee fixing device 8 includes a knee receiving portion 81 that receives the kneecap of the person requiring assistance and two side panels 82 that prevent the knee of the person requiring assistance from shifting in the left-right direction. The torso of the person requiring assistance is fixed by a torso fixing tool 9 described later, so that the kneecap of the person requiring assistance is pressed against the knee receiving part 81.

  A trunk fixture 9 is provided on the upper portion of the column 7. The trunk | drum fixing tool 9 has the abdominal part receiving part 91 which receives the abdomen of a helper. With the abdomen of the person requiring assistance pressed against the abdomen receiving part 91, the torso of the person requiring assistance is fixed to the abdomen receiving part 91 by pressing the abdomen from the lumbar side toward the abdomen receiving part 91 with a belt not shown. Is done.

  In order to maintain the standing position of a person who needs assistance who is difficult to maintain the standing position by himself / herself, it is only necessary to support the sole, knee, and torso. In this embodiment, the sole is pressed against the foot plate 3 by the self-weight of the person requiring assistance by placing the person on the foot plate 3 on the sole. As described above, the torso of the person requiring assistance is fixed to the abdomen receiving part 91 by pressing the abdomen toward the abdomen receiving part 91 with a belt (not shown). As described above, the knee is pressed against the knee support 81 by fixing the torso of the person requiring assistance to the abdomen support 91. By such three-point support, it is possible to maintain the standing position of a person who needs assistance, which is difficult to maintain the standing position by himself.

  A top plate 10 is provided at the upper end of the column 7. The top plate 10 is a flat plate, and of the side walls, the side wall that is contacted by a person requiring assistance is formed in a shape that is recessed forward. With this configuration, as described above, when a person requiring assistance uses the urinal while being placed on the movement assisting tool 200, the body of the person requiring assistance can be brought closer to the urinal. The top plate 10 is provided on the column 7 in a state where it is inclined about 5 degrees toward the rear (toward the person requiring assistance) with respect to the rear portion of the foot plate 3. With this configuration, it is possible to correct the posture by setting the standing posture of the person in need of assistance when the person in need falls to the top board 10 as the correct standing posture.

  The top plate 10 may be provided so that the height and the inclination angle can be adjusted. The structure capable of adjusting the height of the top plate 10 with respect to the foot plate 3 is not particularly limited. For example, the bottom plate of the top plate 10 has a height adjustment shaft that can be inserted into the support column 7 and is locked at an arbitrary height. Alternatively, the height of the top plate 10 may be adjusted by locking at any height among a plurality of heights provided in stages. The structure capable of adjusting the inclination angle of the top plate 10 with respect to the foot plate 3 is not particularly limited. For example, the support column 7 includes a fixed plate at the upper end, and the top plate 10 is attached to the fixed plate via a support arm. The inclination angle of the top plate 10 may be adjusted by attaching to the fixed plate and making it possible to change the support position of the top plate 10 by the support arm.

  By making the height of the top plate 10 adjustable, the height of the top plate 10 can be set to an appropriate position according to the height and physique of the person requiring assistance. Moreover, by making the angle of the top plate 10 adjustable, the angle of the top plate can be set to an appropriate inclination angle depending on the application.

<How to use>
Hereinafter, the usage method of the movement assistance tool 200 of this embodiment is demonstrated.

  Although it is difficult for the person A requiring assistance to maintain the standing position by himself, the right leg moves relatively, so the hinge H of the foot plate 3 is closed so that the second plate 32 is superimposed on the first plate 31. The foot plate 3 is mounted on the base frame 2 in a folded state (with the folded state), and the knee of the left leg is mounted on the foot plate 3 (second plate 32) with the sole of the left leg, which is a non-free leg, resting on the foot plate 3 Is pressed against the knee receiving portion 81 and the torso is fixed to the abdominal receiving portion 91.

  Thereby, the standing position of the person A requiring assistance is maintained. Since the right leg can be freely moved in this state, the sole of the right leg can be brought into contact with the floor through the space S2 provided on the side of the foot plate 8. And the wheel part 4 and the wheel part 6 rotate by kicking a floor surface using a right leg, and the movement assistance tool 200 can be moved to a desired direction by the helper A's intention. As with normal walking, the movement assisting tool 200 can be moved in a comfortable posture by moving the right leg beside the left leg. In addition, it is possible to keep the right leg in front of the body, kick the floor and continue to kick the floor until the right leg is located behind the body. The moving distance of 200 can be a long distance.

  In addition, it is possible for the assistant A who needs help to lean on the top plate with both hands and the upper body, so that the weight of the upper body can be deposited on the top plate, and the position of the center of gravity of the body can be changed by changing the position of drowning with a free caster. A direction in which a certain wheel unit 6 turns and the movement assisting tool 200 advances can be set as a desired direction.

  Since the person B who needs assistance is incapable of using both legs, he cannot drive the movement assisting tool 200 himself. Accordingly, the foot plate 3 is attached to the base frame 2 with the hinge H of the foot plate 3 opened (folded), and the foot rests of both legs are placed on the foot plate 3 with the knee support portion 81 between the feet. The knee is supported, and the torso is fixed by the abdomen receiving portion 91. Thereby, the standing position of the person B who needs assistance is maintained. After confirming that the standing position of the person B requiring assistance is maintained, the assistant pushes or pulls the movement assisting tool 200 to apply a force in the horizontal direction to turn the wheel portion 6, The person B who needs assistance can be moved by rotating the wheel part 4 and the wheel part 6.

  The helper C can move both legs relatively and can stand by himself / herself. Therefore, the movement assisting tool 200 can be used like a walker by removing the foot plate 3 from the base frame 2. The person in need of assistance C can move by turning the wheel portion 6 while walking and rotating the wheel portion 4 and the wheel portion 6.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained.

  In addition, the foot plate is configured such that the first plate and the second plate are rotatably connected via a connecting portion, and one of the plates is rotated with respect to the other plate and can be folded. Alternatively, the first plate and the second plate are detachably provided to the base frame 2 individually. Therefore, if the person requiring assistance places both legs on the foot plate, the plates are aligned, and if the person requiring assistance places one leg on the foot plate, the legs can be easily removed by folding both plates or removing one of the plates. The form of the plate can be switched.

<Supplement>
Although the foot plate 3 is detachable from the base frame 2 in the first embodiment, it may be fixedly attached to the base frame 2. In the second embodiment, the foot plate 3 is foldable and detachable from the base frame 2. However, the foot plate 3 has a length in the horizontal width direction that is substantially half the distance between the two side frames 21. 3 may be fixedly attached to the base frame 2. Even in this configuration, it is possible for a person requiring assistance who can move the other leg relatively, while one leg is inconvenient, to drive the movement assisting tool by himself while receiving standing assistance.

  In the first embodiment and the second embodiment, the number of support columns 7, the number of wheel units 4 and 6, the fixing structure of the body fixing tool, the frame structure of the base frame 2, etc. are within a range that can ensure the safety of the care recipient. You may change suitably.

  In the second embodiment, the space S2 formed by folding the foot plate 3 is formed by being surrounded by four sides of one side frame 21, the sub frame 24, and the left part or the right part of the two connection frames 25. However, it may be formed by opening the rear side. As a specific configuration, for example, by attaching the wheel portion 4 to the rear portion of the sub frame 24, the folded foot plate 3 can be stably supported, and the base frame 2 does not include the rear connection frame 25. Also good. With this configuration, it is possible to prevent the connection frame 25 from hitting the leg when the movement assisting tool 200 is moved by bringing the leg into contact with the floor surface in the space S2.

  In addition, the shape of the foot plate 3 and the mounting structure for the base frame 2 are appropriately changed as long as a space capable of easily kicking the floor surface is formed within the range where the other leg can reach with the one leg fixed. Is possible. For example, as shown in FIG. 14, a part of the rear portion of the foot plate 3 may be recessed in plan view, or the length of the foot plate 3 in the horizontal width direction may be approximately half of the interval between the two side frames 21. It is good also as arrange | positioning so that it can slide to right and left as length.

  Further, the first embodiment and the second embodiment may be combined to form a space behind and on the side of the foot plate 3. In a configuration in which the two plates (the first plate 31 and the second plate 32) constituting the foot plate 3 can be folded or detached individually, the two plates are opened or both plates are attached. Thus, a space is formed behind the foot plate 3. In addition, a space is formed behind and to the side of the foot plate 3 with the two plates folded or with one of the plates removed.

  Specifically, as illustrated in FIGS. 15 to 20, the movement assisting tool 200 according to the modified example of the second embodiment is configured by two plates and can be folded, and the rear end is the rear of the side frame 21. The foot plate 3 is located near the middle between the end and the substantially central portion of the side frame 21 on which the column 7 is erected (that is, the rear end portion is located forward of the rear end portions of the two side frames 21). What is necessary is just to prepare. Moreover, it is good also as a structure which is not provided with the connection frame 25 provided in the rear-end side of the side frame 21 in the structure shown in FIGS.

  In each embodiment, the distance between the wheel parts 6 is wider than the distance between the wheel parts 4. This considers that the force required to fall forward and side is applied to the movement assisting device when the balance is lost because the assistant needs to drive the movement assisting device while keeping the weight on the top plate 10. Is. When both the separation distances are substantially the same, it is weak against a fall to the side, and when the separation distance between the wheel parts 6 is narrower than the separation distance between the wheel parts 4, it is weak against a forward fall. Therefore, by making the separation distance between the wheel portions 6 wider than the separation distance between the wheel portions 4, it becomes a movement assisting tool that is strong against tipping forward and sideways.

  In addition, if both the separation distances are sufficiently secured, it is difficult to fall to the side even if both the separation distances are substantially the same. However, in order to ensure the accessibility to the toilet and the accessibility of the foot plate 3 to the wheelchair as described above. The separation distance between the wheel portions 4 is set to a relatively narrow distance. Therefore, by making the separation distance between the wheel portions 6 wider than the separation distance between the wheel portions 4, the movement assisting tool is strong against the forward and lateral falls.

  INDUSTRIAL APPLICATION This invention can be utilized for the movement assistance tool which assists a helper's movement.
