The handrail body includes a horizontal portion provided substantially parallel to the seating surface of the seat-type toilet, a connecting portion provided at a front end of the horizontal portion with a tip portion facing upward, and a tip portion provided at the tip portion. The above-described placement gripping portion is positioned in front of the front end of the seat-type toilet, and the top surface of the above-described placement gripping portion faces a flat surface or upward. Thus, a handrail for a toilet characterized in that a convex curved surface is formed.

  ADVANTAGE OF THE INVENTION According to this invention, the handrail for toilets which can improve the stability of the operation | movement when a user changes direction in front of a toilet bowl is provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component.
FIG. 1 is a schematic perspective view for illustrating a state where handrails for toilets according to an embodiment of the present invention are arranged around a toilet bowl.
2 is a schematic plan view for illustrating the same state, and FIG. 3 is a schematic side view for illustrating the same state.

As shown in FIGS. 1 to 3, a handrail 1 for a toilet (hereinafter referred to as a handrail 1) includes a handrail body 2, a support portion 3, and a base portion 4.
A pair of handrail bodies 2 are disposed above the left and right sides of a seat-type toilet 100 (hereinafter referred to as toilet 100). Further, the handrail body 2 is provided with a horizontal portion 2a provided substantially parallel to the seating surface of the toilet 100, and an end surface (front end) of the horizontal portion 2a on the front end side of the toilet 100, and the distal end portion is provided on the toilet 100. A connecting portion 2b provided to be inclined toward the upper front side of the connecting portion, and a mounting change gripping portion 2c provided at the tip of the connecting portion 2b.
Note that the “front” of the toilet 100 refers to the direction on the side where the user approaches the toilet 100, as shown in FIG. 10 described later, and “rear” refers to the direction facing the “front”. (Refer to FIGS. 1 to 4, 7, and 10 to 17).

  As will be described later, the horizontal portion 2a is gripped to support the body during movement in the sitting posture or the standing posture, and also serves as an elbow rest in the excretion posture. Here, if a flat part is provided on the upper surface of the horizontal part 2a, the excretion posture can be stabilized by placing an elbow on the flat part. Therefore, it is preferable to provide a flat portion on the upper surface of the horizontal portion 2a. Moreover, it is preferable to provide a curved surface on each ridgeline so that the horizontal portion 2a can be easily grasped. In addition, although the horizontal part 2a illustrated in the figure has a rectangular cross-sectional shape in a direction perpendicular to the axial center, it is not limited to this, and the cross-sectional shape can be changed as appropriate.

The connecting portion 2b also has a substantially rectangular cross section, and is provided so as to be inclined so that the front end portion faces the front upper side. Moreover, the mounting change holding | grip part 2c provided in the front-end | tip part of the connection part 2b is located ahead of the front end of the toilet 100 (refer FIG. 3). Note that the inclination angle of the connecting portion 2b is not particularly limited, and for example, the connecting portion 2b can be erected substantially vertically from the horizontal portion 2a (see FIGS. 6A and 6B). That is, the connection part 2b should just be provided in the front end of the horizontal part 2a with the front-end | tip part facing upwards. However, even in such a case, the placement change gripping portion 2 c is positioned in front of the front end of the toilet 100. Further, the cross-sectional shape of the connecting portion 2b is not limited to a rectangle, and can be changed as appropriate.
In addition, since the user usually approaches the toilet 100 from the front of the toilet 100 and tries to place his / her hand on the highest mounting / holding gripping portion, the switching is performed from obliquely above the mounting / switching gripping portion. A hand is placed on the grip.
At that time, the connecting part 2b is provided with its tip end inclined toward the front upper side of the toilet 100, or a flat surface is formed on the upper surface of the mounting change gripping part provided at the tip of the connecting part 2b. If the flat surface is formed so as to face the front upper side of the toilet 100, it is possible to easily support the load (weight) from the oblique upper side to the mounting change gripping part, and to easily stabilize the posture of the body. Can be made.

  As will be described later, the mounting change gripping portion 2c is gripped in order to stabilize the operation when the user changes the direction in front of the toilet bowl. Moreover, a suitable excretion posture is induced | guided | derived by hold | gripping the mounting change holding | grip part 2c at the time of excretion. For this reason, the upper surface of the mounting change gripping portion 2c is configured to be a flat surface or a convex curved surface (for example, a spherical surface) so that the user can easily grip the mounting change gripping portion 2c. It is preferable to do.

  In consideration of gripping the mounting change gripping portion 2c from above, it is preferable to set the maximum width dimension to a length that can be gripped with one hand. For example, the maximum width dimension of the mounting change holding part 2c can be set to 5 centimeters or less.

  As described above, the mounting change gripping portion 2c is located in front of and higher than the front end of the toilet 100, and its upper surface is a flat surface or a curved surface that is convex upward. Therefore, it is possible to approach the mounting change gripping portion 2c from an arbitrary angle, and it is possible to change the orientation of the posture without changing it. Moreover, since it is ahead and higher than the front end of the toilet 100, it is easy to hold even in a standing posture.

Moreover, the mounting change holding | grip part 2c can also be made rotatable.
FIG. 4 is a schematic perspective view for exemplifying a state in which a handrail for a toilet having a rotatable mounting change gripping portion is disposed around the toilet bowl.
In addition, the same code | symbol is attached | subjected to the part similar to what was demonstrated in FIG. 1, and the description is abbreviate | omitted.

  As shown in FIG. 4, a handrail body 20 is provided on a pair of handrails 1a disposed above the left and right sides of the toilet 100, and the handrail body 20 has a horizontal portion 2a, a connecting portion 2b1, and a mounting change gripping portion 2c1. Is provided. The connecting portion 2b1 is provided on the end surface (front end) of the horizontal portion 2a on the front end side of the toilet 100, and is provided with the tip portion inclined toward the front upper side. And the mounting | wearing change holding | grip part 2c1 is provided in the front-end | tip part of the connection part 2b1 so that rotation is possible.

Next, the rotatable mounting change gripping part 2c1 will be described.
FIGS. 5A and 5B are schematic views for illustrating a rotatable mounting change gripping portion, in which FIG. 5A is a schematic cross-sectional view and FIG. 5B is a schematic exploded view.
As shown in FIG. 5, a connecting portion 2b2 is provided so as to protrude from the end face of the connecting portion 2b1. A groove 2b3 for mounting the shaft retaining ring 2c4 is provided in the vicinity of the end face of the connecting portion 2b2.

  The mounting change gripping part 2c1 has an upper gripping body 2c2 and a lower gripping body 2c3. The upper gripping body 2c2 is provided with a "screw hole" for inserting a mounting screw, and the lower gripping body 2c3 is provided with a "screw portion" for screwing the mounting screw, and the "screw hole" is inserted therethrough. The upper gripping body 2c2 and the lower gripping body 2c3 are integrated by screwing the attachment screw into the “thread portion”. Further, the upper gripping body 2c2 and the lower gripping body 2c3 are formed of curved surfaces, and when the upper gripping body 2c2 and the lower gripping body 2c3 are integrated, the outer shape thereof becomes substantially spherical. ing.

  A stepped hole 2c5 is provided at the center of the lower gripping body 2c3. Further, the stepped hole 2c5 can be inserted through a part of the connecting portion 2b2 and the connecting portion 2b1. When a part of the connecting part 2b2 and the connecting part 2b1 is inserted into the stepped hole 2c5, the groove 2b3 provided in the vicinity of the end face of the connecting part 2b2 protrudes from the upper surface of the lower gripping body 2c3. ing. Then, by attaching the retaining ring for shaft 2c4 to the groove 2b3 protruding from the upper surface of the lower gripping body 2c3, the lower gripping body 2c3 is attached in the vicinity of the end face of the connecting portion 2b1.

  When the lower gripping body 2c3 is attached in the vicinity of the end surface of the connecting portion 2b1, the end surface 2c6 of the large diameter portion of the stepped hole 2c5 and the end surface 2b4 of the connecting portion 2b1 can be brought into contact with each other. Yes. In addition, a gap is provided between the stepped hole 2c5 and the connecting portion 2b2 and the connecting portion 2b1, so that the mounting change gripping portion 2c1 is rotatable while having a certain amount of resistance. Therefore, even if the user holds the placement change gripping part 2c1 from above and puts the weight on it, the user can support it, and the direction of the posture while having a certain resistance to the rotation of the placement changeover holding part 2c1 You can make a change. In this case, for example, the end surface 2c6 of the large-diameter portion of the stepped hole 2c5 and the end surface 2b4 of the connecting portion 2b1 can be brought into surface contact to provide friction resistance.

In this way, the posture can be changed while having a certain degree of resistance to the rotation of the placement change gripping portion 2c1, so that a sense of stability and a sense of security can be improved.
In addition, since the outer shape of the mounting change gripping portion 2c1 is substantially spherical, it is possible to approach the mounting change gripping portion 2c1 from an arbitrary angle, and since it is rotatable, it does not have to be changed. You can change the posture.

  4 and 5 are not limited to the placement change gripping portion 2c1, and a device that makes the placement change gripping portion rotatable can be appropriately selected.

FIG. 6 is a schematic view for illustrating a connecting portion and a mounting change gripping portion according to another embodiment. FIG. 6A illustrates a case where the connecting portion is erected substantially vertically upward from the upper surface of the horizontal portion in the vicinity of the front end of the horizontal portion, and a substantially spherical mounting change gripping portion is provided at the tip of the connecting portion. is there.
In FIG. 6B, one end of the connecting portion having a substantially “U-shape” is provided on the lower surface of the horizontal portion, and the mounting change gripping portion disposed on the front upper side of the horizontal portion is provided at the other end of the connecting portion. The case where it provides is illustrated. In FIG. 6C, the connecting portion is erected from the upper surface of the horizontal portion in the vicinity of the front end of the horizontal portion so as to incline forward and upward, and a substantially cylindrical mounting change gripping portion is provided at the tip of the connecting portion. The case is illustrated.
In FIGS. 6A to 6C, the mounting change gripping part may be fixed to the connecting part or may be provided so as to be rotatable.

  FIG. 6D and FIG. 6E illustrate the case where the upper surface of the mounting change holding portion is a flat surface. 6D illustrates the case where the width dimension of the mounting change gripping portion is substantially constant, and FIG. 6E illustrates the case where the width dimension of the mounting change gripping portion gradually decreases toward the front tip. Is.

  Next, if the position of the placement change gripping part 2c is exemplified, as shown in FIG. 3, the dimension L3 from the front end of the toilet 100 to the end face of the placement change holding part 2c exceeds 0 mm and is 250 mm. It can be as follows. In this case, considering the user's physique and the like, the thickness is preferably 100 mm or more and 150 mm or less. Moreover, the dimension L4 from the upper surface of the horizontal part 2a to the upper end of the mounting change holding | grip part 2c can be 100 mm or more and 150 mm or less. 3A shows a case where the upper surface of the placement change gripping portion is a flat surface, and FIG. 3B shows a case where the placement change gripping portion is substantially spherical.

  Further, when considering that the horizontal portion 2a is used as an elbow rest and the placement change gripping portion 2c is gripped during excretion, the width dimension L1 of the placement change gripping portion 2c is as shown in FIG. It is preferable to be shorter than the width dimension L2 of the horizontal portion 2a. When placing an elbow, it is easier to obtain a sense of stability and security when it has a certain long width dimension. When gripping, the person who has a certain short width dimension grasps the mounting change gripping portion 2c. It is easy. Further, when the width L1 of the mounting change gripping portion 2c is made somewhat short, it is easier to apply force when gripping.

  According to the knowledge obtained by the present inventor, it is preferable that the width dimension L1 and the horizontal part 2a width dimension L2 of the mounting change gripping part 2c are set to about L1: L2 = 1: 1.3-2. In this case, for example, the width dimension L1 of the mounting change holding part 2c can be set to about 35 mm to 45 mm, and the width dimension L2 of the horizontal part 2a can be set to about 60 mm.

  The support portion 3 includes an arm portion 3b having a substantially cylindrical shape, a connecting portion 3a provided at one end of the arm portion 3b, and a connecting portion 3c provided at the other end of the arm portion 3b. The connecting portion 3 a is connected to the lower surface of the horizontal portion 2 a of the handrail main body 2, and the connecting portion 3 c is connected to the base portion 4. The base portion 4 is provided on both side surfaces of the toilet 100, and the connecting portion 3c is connected to the main surface of the base portion 4 provided in a direction substantially perpendicular to the seating surface of the toilet 100.

  That is, the handrail body 2 is supported by the toilet 100 via the base 4 and the support 3 provided on both side surfaces of the toilet 100. Thus, if the handrail body 2 is supported by the toilet 100, the handrail 1 can be installed with good space efficiency even in a narrow toilet room. Moreover, the same arrangement | positioning form is employable also when the shape of a toilet room differs. In addition, since complications can be reduced, merchantability can be improved.

  However, this invention is not necessarily limited to this, The toilet part 100 and the handrail 1 can also be arrange | positioned separately by providing the base part 4 in the floor surface and wall surface of a toilet room.

  Further, for example, the attachment hole of the base part 4 can be a long hole, and the attachment position of the base part 4 can be adjusted in the front-rear direction of the toilet 100. If it does in that way, according to a user's physique etc., the dimension L3 from the front end of the toilet bowl 100 to the end surface of the mounting change holding | grip part 2c can be adjusted.

  The material of the handrail main body 2, the support part 3, and the base part 4 is not particularly limited, but it is preferable to use a material having corrosion resistance in consideration of being used around water. As such a material, for example, a metal material such as stainless steel, a synthetic resin material, a metal material plated or coated with a corrosion-resistant material can be used.

Next, the excretion posture will be described.
FIG. 7 is a schematic diagram for explaining the excretion posture.
For comfortable excretion, it is preferable to increase the abdominal pressure by tilting forward and to stretch the muscles of the abdomen moderately by stretching the stool from the anus. In this case, if the sitting posture is unstable, unrelated muscles are strained to support the posture, and the abdominal muscle necessary for excretion does not enter, and the abdominal pressure cannot be increased. Therefore, in order to excrete comfortably, it is necessary to stabilize the sitting posture.

  Moreover, if a proper forward leaning posture is adopted, the rectal anal angle becomes large and stool is likely to appear. In addition, the abdominal muscles become tight and the abdominal pressure becomes high, so that it is possible to excrete without forcibly. It can also prevent blood pressure from rising too much. Therefore, in order to excrete comfortably, it is necessary to take an appropriate forward leaning posture.

  As described above, in order to obtain an excretion posture that allows comfortable excretion, it is necessary to stabilize the seating posture and to make the seating posture an appropriate forward leaning posture. Here, while the height of the toilet 100 to the toilet seat is substantially constant, there is a great difference in the physique of the user. Therefore, depending on the height of the toilet 100 to the toilet seat and the physique of the user, the seating posture may become unstable, and the seating posture may not be a forward leaning posture.

  For example, a tall user has a long lower leg, so that the user can attach the heel to the floor while sitting. Also, the seating position on the toilet seat can be an appropriate place. Therefore, a tall user can easily stabilize the sitting posture and can easily take an appropriate forward leaning posture. As a result, an appropriate excretion posture can be taken relatively easily.

  On the other hand, users with short stature have short leg lengths, so the heels float off the floor when seated. Also, the seating position on the toilet seat is ahead of the appropriate place. Therefore, a user with a short height becomes unstable in the sitting posture, and it is difficult to take a forward leaning posture as it is. Therefore, it becomes difficult to take an appropriate excretion posture.

  As shown in FIG. 7, the handrail 1 which concerns on this Embodiment is provided with the mounting | wearing conversion holding | grip part 2c ahead from the toilet bowl front end. And a body can be bent forward naturally by holding | griping the mounting change holding | grip part 2c at the time of excretion. Therefore, a forward leaning posture suitable for excretion can be taken regardless of the user's physique. In addition, since the weight can be supported by gripping the mounting change gripping portion 2c, the sitting posture can be stabilized regardless of the user's physique. As a result, regardless of the user's physique, an excretion posture suitable for comfortable excretion can be achieved.

FIG. 8 is a graph for illustrating the relationship between the sitting posture and the rectus abdominis muscle activity.
The vertical axis represents the rate of change in the muscle activity of the rectus abdominis muscle when sitting on the toilet seat from a stationary standing state. In this case, it means that the greater the rate of change, the greater the force is applied to the rectus abdominis muscle. The horizontal axis represents the angle between the thigh and the horizontal plane. In this case, 0 ° represents the horizontal, and 10 ° and 20 ° represent that the inclination of the thigh is 10 ° and 20 ° from the horizontal to the lower side, respectively. In addition, bar graphs (1) to (3) are in a state where the basket is on the floor, and bar graphs (4) and (5) are in a state where the basket is floating from the floor.

  Bar graphs (1) to (3) show a situation where the user has a short leg (short stature) sitting in front of the toilet seat (so-called “sitting-down state”). The inclination is 10 ° and 20 ° downward from the horizontal. In such a case, it can be seen that as the thigh angle increases, the sitting posture becomes unstable, and the rate of change in the muscle activity of the rectus abdominis muscle also decreases. That is, it can be seen that in an unstable sitting posture, the rate of change in the muscle activity of the rectus abdominis muscles decreases and no force is applied to the rectus abdominis muscles.

  The bar graphs (4) and (5) show that the user with short leg length (short height) is sitting at a proper position relatively behind the toilet seat and the heel is floating from the floor. The thigh angle is 0 ° (horizontal). In such a case, since the sitting posture can be stabilized even in the case of a user with short leg length (short height), the rectus abdominis muscle as compared with the cases of the bar graphs (2) and (3) The rate of change in muscle activity can be increased. That is, it can be seen that if the sitting posture is stabilized, the rate of change in the muscle activity of the rectus abdominis muscles can be increased, and power can be applied to the rectus abdominis muscles.

  Further, the bar graph (4) is a case where the placement change gripping portion 2c is not gripped, and the bar graph (5) is a case where the placement change gripping portion 2c is gripped. By grasping the mounting change gripping portion 2c positioned in front of the front end of the toilet bowl, the body can be naturally bent forward, and a forward leaning posture suitable for excretion can be taken regardless of the physique of the user. As a result, the abdominal muscles become tight and the abdominal pressure increases, so that the rate of change in the muscle activity of the rectus abdominis muscles can be increased as shown in the bar graph (5).

FIG. 9 is a graph for illustrating the influence of the use of the handrail on the sitting position.
The vertical axis represents the difference between the reference seating position and the actual seating position. In this case, 0 represents the reference seating position, and the larger the numerical value, the more the seating is in front of the toilet seat (so-called light sitting). Further, the smaller the numerical value is, the more seated behind the toilet seat (the so-called deep sitting state). At this time, the seating posture becomes unstable in a state of being seated in front of the toilet seat (so-called shallow sitting state), and in a state of being seated behind the toilet seat (so-called deep seating state), the seating posture is stable.

  Also, when the bar graph (1) is seated on a toilet without a handrail, the bar graph (2) is when the height of the toilet seat is adjusted to the length of the user's lower leg, and the bar graph (3) is When a horizontal handrail is provided on the side, the bar graph (4) is provided with a vertical handrail in front of the toilet bowl. When the bar graph (5) is provided on the elbow rest, the horizontal handrail provided on the side of the toilet bowl is provided. This is the case when it can be used. In addition, the user is a person whose short leg length is short (height is short).

  From the bar graph (1), it can be seen that if the handrail is not used, the seating position becomes too forward. Also, from the bar graphs (3) and (4), it can be seen that if the handrail is used, the seating position approaches the reference seating position, but the seating position is still forward.

  Here, as can be seen from the bar graph (2), if the height of the toilet seat is adjusted according to the length of the user's lower leg, the seating position can be shifted backward, so that the seating posture can be stabilized. it can. However, a separate means for adjusting the height of the toilet seat is required, which complicates the toilet structure and increases the cost.

  On the other hand, if the horizontal part 2a which can be used also for an elbow rest is provided like the handrail 1 which concerns on this Embodiment, a seating position will be shifted back so that a bar graph (5) may show. Can do. Therefore, the sitting posture can be stabilized without complicating the toilet structure and increasing the cost.

  Moreover, since the mounting change gripping part 2c and the horizontal part 2a of the handrail 1 according to the present embodiment are connected via the connecting part 2b, the mounting change holding part can be obtained by placing an elbow on the horizontal part 2a. 2c can be guided to grip. Moreover, since the horizontal part 2a can support continuously from a wrist to an elbow when the mounting | wearing change holding | grip holding part 2c is hold | gripped, a sense of security and a sense of stability can be obtained.

  For convenience of explanation, a pair of handrails 1 are provided on the left and right sides of the toilet 100, but it is sufficient that the handrails 1 are provided on at least one side. However, if it is assumed that a pair is provided on both the left and right sides of the toilet 100, the approach is easy in both the standing state and the sitting state.

Next, the usage pattern of the handrail 1 according to the present embodiment will be illustrated.
FIGS. 10-13 is a schematic diagram for illustrating the usage form from a standing state to a seating.
FIG. 14 is a schematic diagram for illustrating a usage pattern during excretion.
FIG. 15 to FIG. 17 are schematic views for illustrating usage patterns from a sitting state to standing up.

  As shown in FIG. 10, the user who has moved to the front of the toilet seat grips the placement change gripping portion 2 c while standing. At this time, since the position of the placement change gripping portion 2c is the highest, in the case of the standing posture, the placement change gripping portion 2c having the highest position can be easily gripped. Moreover, since the flat surface (or curved surface convex upward) is provided on the upper surface of the mounting change gripping portion 2c and the width dimension L1 is also a size suitable for gripping, the mounting change gripping portion 2c is It can be easily grasped from above the front, and the rotation of the body described later can also be facilitated. In addition, since the standing posture can be stabilized by gripping the placement change gripping portion 2c, it is possible to prevent falls and the like.

  Next, as shown in FIG. 11, the posture direction is converted in front of the toilet 100. At this time, it is possible to rotate the body around the mounting change gripping part 2c gripped with one hand and grip the horizontal part 2a with the other hand. For this reason, the orientation of the posture can be changed while the body is supported. Further, if the placement change gripping portion 2c is rotatable, the body can be rotated without changing the placement change gripping portion 2c. In this case, if a certain amount of resistance is given to the rotation of the placement change gripping portion, a sense of stability and a sense of security can be given when changing the direction of the posture. Moreover, if the curved surface is provided in the ridgeline of the horizontal part 2a, the holding | grip of the horizontal part 2a can be made still easier.

  Next, as shown in FIG. 12, the posture is reversed 180 degrees in front of the toilet 100, and the body is moved to the vicinity of the seating position. At this time, it is possible to move the body while grasping the horizontal portions 2a on both sides with both hands and sliding on the horizontal portions 2a. Therefore, even when moving backward with the body inverted, the body can be supported by the horizontal portion 2a, and the horizontal portion 2a also serves as a guide in the moving direction, so that stable movement is performed. Can do.

  Next, as shown in FIG. 13, the user sits on the toilet seat of the toilet 100. At this time, both hands can hold the horizontal portions 2a on both sides and sit while supporting the body. When the seating position is inappropriate, the user can move on the toilet seat by grasping the horizontal portion 2a and pulling or pushing the body. Therefore, stable seating and movement on the toilet seat can be performed while supporting the body.

  Next, as shown in FIG. 14, the placement change gripping portion 2 c is gripped. As described above, the body can be bent forward naturally by gripping the placement change gripping portion 2c during excretion. Therefore, a forward leaning posture suitable for excretion can be taken regardless of the user's physique. In addition, since the weight can be supported by gripping the mounting change gripping portion 2c, the sitting posture can be stabilized regardless of the user's physique. As a result, an excretion posture suitable for comfortable excretion can be taken regardless of the user's physique.

  In addition, since the placing change gripping part 2c and the horizontal part 2a are connected via the connecting part 2b, guiding the placing change holding part 2c by holding an elbow or the like on the horizontal part 2a. Can do. Moreover, since the horizontal part 2a can support continuously from a wrist to an elbow when the mounting | wearing change holding | grip holding part 2c is hold | gripped, a sense of security and a sense of stability can be obtained.

  Next, as shown in FIG. 15, the forward tilt posture for standing is induced by gripping the vicinity of the distal end portion of the mounting change gripping portion 2c. At this time, it can be gripped by hooking a finger on the placement change gripping portion 2c. And the standing operation | movement mentioned later can be smoothly performed by hold | gripping as a finger | toe is hooked on the mounting change holding | grip part 2c.

  Next, as shown in FIG. 16, the standing change operation is performed by pushing the placement change gripping portion 2c with the palm of the hand. At this time, it is possible to press and hold the mounting change gripping portion 2c with the palm of the hand. Therefore, the standing motion can be assisted by pushing the placement change grip 2c with the palm, and the body can be supported during the standing motion by gripping the placement change grip 2c. As a result, a stable standing motion can be smoothly performed while the body is supported.

  Next, as shown in FIG. 17, it stands in the state which hold | gripped the mounting change holding | grip part 2c. At this time, since the position of the placement change grip portion 2c is the highest, the placement change grip portion 2c can be easily gripped even in the case of the standing posture.
