It may be a seating operation assisting detection means configured to output a signal indicating that to the braking means 4 and operate the braking means 4.
In these cases, the braking of the braking means 4 is released by turning off the power key switch 70B after the standing operation is completed or the sitting operation is completed. Therefore, the user A holds the handle grip 77 after the standing operation is completed. I can walk. In addition, the walking support device 1 that has been disconnected from the user A after the seating operation is completed can be moved by rolling the wheels 32.

In the user fall prevention means, when the user A is walking or standing while being connected to the device main body 5 via the fitting B and the connecting means 6, the user A loses his / her posture and the user A When the other end side of the connecting means 6 connected to the fitting B is pulled out of the support base 73 of the device main body 5 by a predetermined length, the moving means is used to stabilize the walking support device 1. This is a means for preventing the user A from tipping over by operating the braking means 4 of 3 to brake the wheels 32.
The user fall prevention means includes a braking means 4 for stopping the rotation of the wheel 32 and a pull-out amount detecting means for detecting that the other end side of the connecting means 6 is pulled out of the support base 73 by a predetermined length. The braking means 4 is configured to operate when it is detected by the pull-out amount detecting means that the other end side of the connecting means 6 is pulled out to the outside of the support base 73 by a predetermined length.
That is, the user fall prevention means includes a pull-out amount detecting means (detecting means) for detecting that the other end side of the connecting means 6 is pulled out of the device main body 5 by a predetermined length a, and the detecting means. Activates the braking means 4 when it is detected that the other end side of the connecting means 6 is pulled out of the device main body 5 by a predetermined length (a1 + a2).

As shown in FIG. 5, the pull-out amount detecting means includes a fixed pulley group, a first moving pulley 42, a spring 43 such as a coil spring as an elastic means for pulling the first moving pulley 42 with a predetermined force, and a spring 43. It is provided with a pull-out amount detection unit, and is configured to operate the braking means 4 based on a detection signal from the pull-out amount detection unit.

As shown in FIG. 5A, one end of the connecting means 6 is connected to the weight unloading means 9, and the other end of the connecting means 6 is the first fixed pulley 41a provided in the box 91, and The second fixed pulley 41b, the first moving pulley 42, which are guided to the hollow portion 73X through the inlet hole 73e to the hollow portion 73X provided on the lower side of the support base 73 and are provided in the hollow portion 73X. After passing through the third fixed pulley 41c, it is pulled out to the outside of the hollow portion 73X via the outlet hole 73f from the hollow portion 73X via the elastic support means described later, and the other end of the pulled out connecting means 6. The connector 61 is attached to the. The diameter of the outlet hole 73f is formed so that the connecting tool 61 provided at the other end of the connecting means 6 cannot pass through.
Further, the spring 43 is installed in a cylindrical spring accommodating portion 44 provided in the hollow portion 73X and extending in the front-rear direction, and can be expanded and contracted in the extending direction of the spring accommodating portion 44. That is, one end 43a of the spring 43 is fixed to the inner surface on the one end side in the extension direction of the spring accommodating portion 44, and the other end 43b side of the spring 43 can move along the extension direction of the spring accommodating portion 44.

The withdrawal amount detection unit is configured to include, for example, a movable body 45, a regulation unit 46 that regulates the movement of the movable body 45, and a detection body (not shown) provided in the regulation unit 46.
The regulating portion 46 is provided on the other end side of the spring accommodating portion 44 in the extension direction.
The movable body 45 is fixed to the other end 43b of the spring 43 and is connected to the first moving pulley 42 by a linear connecting body 47 such as a wire. The linear connecting body 47 passes through the through hole 46a formed in the regulating portion 46 and the through hole 44a formed in the other end wall in the extension direction of the spring accommodating portion 44, and one end thereof is connected to the movable body 45. The other end is connected to the first moving pulley 42.

When the connecting means 6 is not connected to the user A via the fitting B, the connecting means 6 is connected until the connecting tool 61 provided at the other end of the connecting means 6 comes into contact with the peripheral edge of the outlet hole 73f. Is in the initial state shown in FIG. 5A, which is pulled by the force of the spring 43 and the elastic means 53 of the elastic supporting means described later. In the initial state, the distance between the movable body 45 and the regulating portion 46 is separated by a distance a2.
Then, in a state where the connecting means 6 is connected to the user A via the fitting B, as shown in FIG. 5B, the user A loses his / her posture and is connected to the wearing tool B of the user A. When the other end side of the connecting means 6 is pulled out of the support base 73 by a predetermined length (a1 + a2), the moving pulley 42 moves by a distance a2 in the direction of pulling the spring 43 through, for example, the slide rail hole 42a. Then, the movable body 45 comes into contact with the regulation unit 46, and the detector provided in the regulation unit 46 outputs the detection signal to the braking means 4 via a wired or wireless connection.

The detector is, for example, an electric switch that is turned on when the movable body 45 comes into contact with the regulating portion 46 and is turned off when the movable body 45 is separated from the regulating portion 46, or the movable body 45 comes into contact with the regulating portion 46. It is composed of a sensor or the like that detects this.
In this case, as the braking means 4, a brake such as an electromagnetic brake or a drum brake using a power source such as an electromagnet, a hydraulic cylinder, or an air cylinder that can be electrically controlled is used.
Then, when the braking means 4 inputs a detection signal from the detector, the power sources such as the electromagnet, the hydraulic cylinder, and the air cylinder of the braking means 4 operate to brake the wheels 32.

The elastic support means applies a tensile force to the other end of the connecting means 6 provided with the connecting tool 61 in the direction of approaching the device main body 5, and the other end of the connecting means 6 in the direction away from the device main body 5. It is a means for supporting the connecting means 6 so as to be movable.
The elastic support means includes an elastic means 53 and a second moving pulley 54 as a moving pulley that is connected to the other end (connecting end) 53x of the elastic means 53 and is configured to be movable by the elasticity of the elastic means 53. ..
Then, after the other end side of the connecting means 6 via the third fixed pulley 41c has passed through the second moving pulley 54, the other end of the connecting means 6 has passed through the fourth fixed pulley 41d and the outlet hole 73f to form the device main body. The other end of the connecting means 6 which is pulled out to the outside of the device 5 and is configured by attaching the connecting tool 61 to the other end of the connecting means 6 pulled out to the outside of the device main body 5 is outside the device main body 5. Be positioned.
Further, in the second moving pulley 54, the other end of the connecting means 6 moves in a direction away from the device main body 5, so that the second moving pulley 54 moves against the tensile force of the elastic means 53, for example, through the slide rail hole 54a. It is configured in.
With the above configuration, the elastic support means applies a tensile force to the other end of the connecting means 6 provided with the connecting tool 61 in a direction approaching the device main body 5, and the other end of the connecting means 6. It functions as a means for supporting the connecting means 6 so that the portion can be moved away from the device main body portion 5.

As the elastic means 53, it is preferable to use a constant load spring capable of moving the other end of the connecting means 6 in a direction away from the device main body 5 with a constant force. If a constant load spring is used, when a person pulls the other end of the connecting means 6 in a direction away from the device main body 5, this tensile force reaches the maximum return force (maximum tensile force) of the constant load spring. Can move the other end of the connecting means 6 in a direction away from the device main body 5 with a constant tensile force.
That is, a wire spring (coil spring) may be used as the elastic means 53, but in this case, the more the spring is stretched, the larger the tensile force required to stretch the spring is, so that the other end of the connecting means 6 is used. Is required to be moved long in the direction away from the device main body 5 (when the other end side of the connecting means 6 is to be pulled out long), and in the case of the weak user A, the other end of the connecting means 6 is required. It can be difficult to pull out the side for a long time.
On the other hand, when a constant load spring is used as the elastic means 53, the other end of the connecting means 6 can be moved long in the direction away from the device main body 5 with a small force.
Further, when the constant load spring is used as the elastic means 53, it fits in the accommodating portion 53a of a drum or the like having a small diameter, so that the installation space can be reduced, and there is an advantage that the walking support device 1 can be miniaturized.

For example, normally, the connecting tool 61 is locked to the peripheral edge of the outlet hole 73f by the tensile force of the elastic means 53, and by pulling the connecting tool 61, the other end of the connecting means 6 is attached to the device main body portion 5. It is configured so that it can be separated from the distance a1 (for example, 30 cm). That is, the other end of the connecting means 6 moves away from the outlet hole 73f of the device main body 5, so that the second moving pulley 54 moves in the slide rail hole 54a against the tensile force of the elastic means 53 at a distance a1. It is configured so that it can move only (for example, 30 cm). In this case, the rotation center axis of the second moving pulley 54 moving in the slide rail hole 54a collides with the hole edge of the slide rail hole 54a, so that the movement of the second moving pulley 54 is restricted. Alternatively, a separate stopper may be provided so that the movement of the second moving pulley 54 is restricted.

Therefore, the user A wearing the fitting B moves the other end of the connecting means 6 provided with the connecting tool 61 in a direction away from the outlet hole 73f of the device main body 5 by a distance a1 (for example, 30 cm) (for example, 30 cm). Since the connecting means 6 can be pulled out), the work of connecting the connecting tool 61 of the connecting means 6 and the connecting portion C of the mounting tool B can be easily performed. That is, when connecting the connecting tool 61 of the connecting means 6 and the connecting portion C of the mounting tool B, the other end of the connecting means 6 is easily moved in a direction away from the outlet hole 73f of the device main body 5 (easy). It is possible to provide a walking support device 1 that can be pulled out.
That is, even if the height of the seating position of the seating portion D of the chair or the like on which the user A is seated varies, the connecting portion 61 of the connecting means 6 is attached to the connecting portion C of the fitting B to which the user A is attached. Since it can be easily moved to the position, the user A can easily perform the connecting work between the connecting means 6 and the fitting B.
Further, after the user A wearing the fitting B connects the connecting tool 61 provided at the other end of the connecting means 6 and the connecting portion C of the mounting tool B, the user A may lose his / her posture and fall down. When the other end side of the connecting means 6 is pulled out of the support base 73 by a predetermined length (a1 + a2), the braking means 4 inputs a detection signal from the detector of the pull-out amount detecting unit to input the detection signal to the wheel 32. Prevents the walking support device 1 from moving on the road surface R by the moving means 3 when the user A loses his / her posture and tries to fall while walking or standing up. Since the walking support device 1 is stable, it is possible to prevent the user A from falling due to the walking support device 1 moving in a state where the user A loses his / her posture and is about to fall. Become. That is, it is possible to provide the walking support device 1 capable of preventing the user A from falling while walking or standing up.
When the user A is walking or standing and tries to fall down by losing his posture, the elastic means 53 is activated first and the other end of the connecting means 6 is separated from the device main body 5. After moving by the distance a1, the spring 43 operates and the other end 43b of the spring 43 moves by the distance a2, so that the other end of the connecting means 6 is only a distance (a1 + a2) from the outlet hole 73f of the device main body 5. When the wheel 32 moves away from the wheel, the braking means 4 is configured to input a detection signal from the detector of the pull-out amount detecting unit to brake the wheel 32.

Further, when a mechanical brake such as a caliper brake that pushes the brake pad against the wheel 32 to stop the rotation of the wheel 32 by pulling the brake wire is used as the braking means 4, it is used as follows. A person's fall prevention means may be configured.

In this case, as shown in FIG. 6, the user fall prevention means is when the user A is walking or standing up while being connected to the device main body 5 via the fitting B and the connecting means 6. The other end of the connecting means 6 connected to the fitting B of the user A when the user A loses his / her posture is the support base 73 of the device main body 5 by the distance (a1 + a2) from the outlet hole 73f of the device main body 5. When pulled out, the brake wire 49 of the braking means 4 is pulled to stop the rotation of the wheel 32.
That is, the user fall prevention means is the brake wire of the braking means 4 when the other end of the connecting means 6 is pulled out of the device main body 5 by a distance (a1 + a2) from the outlet hole 73f of the device main body 5. The braking means 4 is operated by pulling the 49.

That is, as shown in FIG. 6, the user fall prevention means is a long hole 44c formed on the peripheral wall on the other end side of the extension direction of the spring accommodating portion 44 so as to extend in the extension direction of the spring accommodating portion 44. A movable body 50 having a connecting portion 51 fixed to the other end 43b of the spring 43 and projecting to the outside of the spring accommodating portion 44 via the elongated hole 44c, and one end to an arm such as a caliper brake (not shown). A wire 49 or the like which is connected and has a brake wire 49 whose other end is connected to the connecting portion 51 of the movable body 50 and is passed through a through hole 44a formed in the other end wall of the cylinder of the spring accommodating portion 44 in the extension direction. One end of the linear connecting body 47 and the movable body 50 are connected, and the other end of the linear connecting body 47 and the moving pulley 42 are connected.
The other end of the brake wire 49 is guided rearward via the fixed pulley 52 and connected to the connecting portion 51 of the movable body 50.
In FIG. 6, the same parts as those in FIG. 5 are designated by the same reference numerals and the description thereof will be omitted.

In this case, after the user A wearing the fitting B connects the connecting tool 61 provided at the other end of the connecting means 6 and the connecting portion C of the fitting B, the user A loses his / her posture and uses it. The other end side of the connecting means 6 connected to the fitting B of the person A is pulled out from the outlet hole 73f of the device main body 5 by a predetermined length (a1 + a2) to the outside of the device main body 5, and the spring 43 is pulled. As a result, when the brake wire 49 is pulled and the movable body 50 and the inner surface 44x of the other end of the cylinder of the spring accommodating portion 44 in the extension direction come into contact with each other, the brake pad of the braking means 4 is pressed against the wheel 32 and the wheel 32 is pressed. Is configured to stop the rotation of.
Therefore, when the user A tries to fall, the walking support device 1 can be prevented from moving on the road surface R by the moving means 3, and the user A can be prevented from falling.

That is, in the case of the walking support device 1 of the first embodiment in which the device main body 5 includes the weight unloading means 9, the standing motion support means, the seating motion support means, the user fall prevention means, and the elastic support means, the connecting means. One end of 6 is connected to the weight unloading means 9, and the other end of the connecting means 6 is connected to the first fixed pulley 41a provided in the box 91 and the hollow portion 73X provided under the support base 73. The second fixed pulley 41b, the first moving pulley 42, and the third fixed pulley 41c are guided to the hollow portion 73X through the inlet hole 73e of the above and provided in the hollow portion 73X of the support base 73. 3 The other end of the connecting means 6 via the fixed pulley 41c passes through the second moving pulley 54, and then the other end of the connecting means 6 passes through the fourth fixed pulley 41d and is outside the outlet hole 73f of the device main body 5. A connecting tool 61 is provided at the other end of the connecting means 6 located outside the outlet hole 73f. Then, the first moving pulley 42 and the other end 43b of the spring 43 are connected via the movable body 45 and the linear connecting body 47 to form the user fall prevention means. Further, the second moving pulley 54 and the other end (connecting end) 53x of the elastic means 53 are connected to form the elastic supporting means.

The wheels 32 that operate the braking means 4 by the standing motion supporting braking means, the sitting motion supporting braking means, and the user fall prevention means of the present invention are two wheels 32 provided on the left and right rear sides of the base 2. It may be only, or it may be all the wheels 32 constituting the transportation means 3.

Embodiment 2
Further, the braking means for supporting the standing motion, the braking means for supporting the sitting motion, the user fall prevention means, and the elastic support means of the present invention can be applied to a walking support device having a configuration not provided with the weight unloading means 9.
In this case, the braking means for supporting the standing motion, the braking means for supporting the sitting motion, and the elastic support means are configured in the same manner as in the first embodiment.
Further, as shown in FIG. 7, the user fall prevention means has a configuration in which one end of the connecting means 6 is connected to the movable body 45 fixed to the other end of the spring 43 described above, or as shown in FIG. In addition, one end of the connecting means 6 may be connected to the movable body 50 fixed to the other end side of the spring 43 described above.
In FIG. 7, the same parts as those in FIG. 5 are designated by the same reference numerals and the description thereof will be omitted.
Similarly, in FIG. 8, the same parts as those in FIG. 6 are designated by the same reference numerals and the description thereof will be omitted.
That is, even in a walking support device not provided with the weight unloading means 9, it is possible to provide a braking means for standing motion support, a braking means for seating motion support, a user fall prevention means, and an elastic support means. ..

That is, in the case of the walking support device 1 of the second embodiment, in which the device main body 5 includes the standing motion support means, the seating motion support means, the user fall prevention means, and the elastic support means, and does not include the weight unloading means 9, they are connected. A user fall prevention means is configured in which one end of the means 6 is connected to the other end 43b side of the spring 43. Further, the other end of the connecting means 6 passes through the fixed pulley 41A and the moving pulley 54A provided in the hollow portion 73X, and then the other end of the connecting means 6 passes through the fixed pulley 41B and exits the device main body 5. A connecting tool 61 is provided at the other end of the connecting means 6 located outside the outlet hole 73f and is configured to be located outside the 73f. Then, the moving pulley 54A and the other end (connecting end) 53x of the elastic means 53 are connected to form the elastic supporting means.

Further, in the configurations shown in FIGS. 7 and 8, a walking support device having a weight unloading function can be configured by using a spring that also functions as a weight unloading means as the spring 43.

Embodiment 3
In the first and second embodiments, the configuration is provided with an auxiliary support column having the lower auxiliary support column 75 and the upper auxiliary support column 73b, but in the case of the configuration provided with the auxiliary support column, the lower auxiliary support column 75 And the lower support column 74 are connected so as to form a V shape, so that the upper auxiliary support column 73b inserted in the lower auxiliary support column 75 and the upper support column 73a inserted in the lower support column 74 are moved in the vertical direction. It can be difficult to get it done.
In the first and second embodiments, for example, the outer diameter dimension of the upper support column 73a is extremely smaller than the inner diameter dimension of the lower support column 74, and the outer diameter dimension of the upper auxiliary column 73b is the inner diameter dimension of the lower auxiliary column 75. If it is extremely smaller than the dimensions, the upper support column 73a and the upper auxiliary support column 73b will rattle. Therefore, in the first and second embodiments, the outer diameter dimension of the upper support column 73a is slightly smaller than the inner diameter dimension of the lower support column 74, and the outer diameter dimension of the upper auxiliary column 73b is larger than the inner diameter dimension of the lower auxiliary column 75. The upper support column 73a is fitted into the lower support column 74, and the upper auxiliary support column 73b is fitted into the lower auxiliary support column 75 so as to be slightly smaller. That is, the upper support column 73a is slid in the lower support column 74, and the upper auxiliary support column 73b is slid in the lower auxiliary support column 75 so as to move in the vertical direction. , The upper auxiliary support column 73b is configured so as not to cause rattling.
However, in the case where the upper support column 73a and the upper auxiliary support column 73b are slidably moved in the vertical direction in this way, the upper support column 73a and the upper auxiliary support column 73b are moved in order to adjust the height of the support base. If the upper support column 73a and the upper auxiliary support column 73b are tilted even a little when moving in the vertical direction, the frictional resistance between the outer surface of the upper support column 73a and the inner surface of the lower support column 74 and the outer surface of the upper auxiliary support column 73b The frictional resistance with the inner surface of the lower auxiliary strut 75 increases, and it becomes difficult to move the upper strut 73a and the upper auxiliary strut 73b in the vertical direction in order to adjust the height of the support base.
Therefore, as a configuration without an auxiliary support, the height of the support base 73 can be adjusted according to the height of the user A by moving the upper support support 73a in the vertical direction with respect to the lower support support 74. If the configuration is provided with an adjusting mechanism, it becomes easy to move the upper support column 73a in the vertical direction with respect to the lower support column 74.
That is, the left strut 71 and the right strut 72 are configured to include a lower strut 74 and an upper strut 73a, respectively, and the lower strut 74 has a lower end (one end) via a hinge 74a on the front side of the base 2. The upper support column 73a is configured to be movable along the extension direction of the lower support column 74 so that the height of the support portion attached to the upper end side (the other end side) can be changed. It was configured to be attached to the lower support column 74.
However, even in the configuration of the third embodiment, if the upper support column 73a is moved in the vertical direction while the upper support column 73a is tilted, the frictional resistance between the outer surface of the upper support column 73a and the inner surface of the lower support column 74 becomes large. Therefore, it may be difficult to move the upper support column 73a in the vertical direction in order to adjust the height of the support base 73.
Therefore, the height adjustment work of the support base 73 can be easily performed by adopting the configuration as in the fourth embodiment described below.

Embodiment 4
The walking support device 1 of the fourth embodiment will be described with reference to FIGS. 9 and 10. In FIGS. 9 and 10, the connecting means 6, the elastic supporting means, the user's fall prevention means, the weight unloading means 9, the handle grip 77, the elevating lever 78, the outrigger 10 and the like are not shown. Further, in FIGS. 9 and 10, the same parts as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted.
In the walking support device 1 of the third embodiment, the left and right columns 71A; 72A are provided with an upper column 93 and a lower column 94, respectively.
The upper column 93 is composed of a hollow column such as a pipe whose upper end side (other end side) is connected to the lower surface of the support base 73 of the support portion and whose lower end opens.
The lower end (one end) of the lower column 94 is swingably attached to the front side of the base 2 via a hinge 74a, and the upper end side (the other end) is the lower end opening of the hollow column constituting the upper column 93. It consists of columns inserted into more hollow columns.
That is, the upper support column 93 is attached to the lower support column 94 so that it can move along the extension direction of the lower support column 94 and the height of the support base 73 attached to the upper end side can be changed. And said.
That is, a view provided on the height positioning hole of any one of a plurality of height positioning holes (not shown) provided on the lower support column 94 along the central axis 94C at predetermined intervals and on the upper support column 93. The height of the support base 73 is adjusted according to the height of the user A by fitting a fixing means such as a fixing screw (not shown) into these height positioning holes in a state where the height positioning holes are matched with the outside height positioning holes. It is equipped with a support base height adjustment mechanism that is configured so that it can be used.

Further, the walking support device 1 of the third embodiment includes left and right mounting columns 95, 95 provided so as to extend upward on the rear side of the base 2. That is, left and right mounting columns 95 and 95 provided so as to extend upward are provided on the rear end side of the left portion 22 of the base frame and the rear end side of the right portion 23 of the base frame, respectively.
Then, one end of the cylinder 8, that is, the case 81, so that the cylinder 8 can be installed so that the extension direction of the central axes 8C of the left and right cylinders 8 and 8 as the telescopic means serving as the actuator approaches the horizontal direction. One end is swingably attached to the upper end side of the mounting column 95 via a hinge 8a, and the other end of the cylinder 8, that is, the other end of the rod 82 is substantially in the extension direction of the lower column 94. It was configured to be swingably attached to an intermediate position via a hinge 8b.
In this way, since the mounting column 95 to which one end of the cylinder 8 is attached is provided so as to rise from the base 2, the cylinder 8 can be installed so that the extension direction of the central axis 8C of the cylinder 8 approaches the horizontal direction. As a result, the driving force for driving the rod 82 of the cylinder 8 can be reduced, and a small and inexpensive cylinder 8 having a small driving output can be used. Therefore, the cost of the walking support device 1 can be reduced. You will be able to plan.
That is, as the extension direction of the central axis 8C of the cylinder 8 approaches the vertical direction, a large driving force for moving the rod 82 against gravity is required when moving the rod 82 upward, which is large and expensive with a large drive output. It is necessary to use a cylinder, but if the cylinder 8 is installed in a state where the extension direction of the central axis 8C of the cylinder 8 approaches the horizontal direction, the influence of gravity becomes small when the rod 82 is moved, so that the cylinder The driving force for driving the rod 82 of 8 can be reduced, and a small and inexpensive cylinder 8 having a small driving output can be used.

Further, the walking support device 1 of the third embodiment includes left and right connecting mechanisms 96 and 96 for connecting the upper end portion of the mounting column 95 and the lower end portion of the upper column 93.
The connecting mechanism 96 includes, for example, a pipe 97 having one end swayably mounted above the one end mounting position (hinge 8a) of the cylinder 8 on the mounting column 95 via a hinge 97a, and one end. It is swingably attached to the lower end of the upper support column 93 via a hinge 98a, and the other end side is provided with a slide member 98 inserted into the pipe 97 via the other end opening 97b of the pipe 97 so as to be expandable and contractible. It is configured.

That is, in the walking support device 1 of the third embodiment, the left and right columns 71A; 72A composed of the upper column 93 and the lower column 94, and the upper end of the mounting column 95 and the lower end of the upper column 93 are shaken. It is provided with a support base height adjusting mechanism having left and right connecting mechanisms 96 and 96 that are movably connected.
By providing the support base height adjusting mechanism, when the upper support column 93 is moved in the vertical direction, one end of the slide member 98 of the connecting mechanism 96 and one end of the pipe 97 swing, so that the upper support column The central axis 93C of 93 and the central axis 94C of the lower support column 94 come to coincide with each other, and the frictional resistance between the inner surface of the upper support column 93 and the outer surface of the lower support column 94 becomes smaller. As shown, since the upper support column 93 can be easily moved in the vertical direction, the support base height adjustment work becomes easy.
Further, as shown by arrow R in FIG. 10, during the standing motion support and the sitting motion support, the slide member 98 moves in the pipe 97 in the direction along the central axis 97C of the pipe 97 as the cylinder 8 expands and contracts. As it moves, the connecting mechanism 96 also expands and contracts.

That is, according to the walking support device 1 of the third embodiment, since the connecting mechanism 96 is provided, when the upper support column 93 is moved in the vertical direction, the central axis 93C of the upper support column 93 and the central axis of the lower support column 94 It is set in a state where it always matches with 94C. Therefore, the frictional resistance between the outer surface of the upper support column 93 and the inner surface of the lower support column 94 is reduced, and the upper support column 93 can be smoothly slid in the vertical direction. It will be easy.

A walking support device having a configuration that does not include the connecting mechanism 96 of the walking support device 1 shown in FIG. 9 may be used, but in this case, it is the same as the walking support device 1 having the configuration shown in the first to third embodiments. In addition, if the upper column is moved in the vertical direction while the upper column is tilted, the frictional resistance between the inner surface of the upper column and the outer surface of the lower column increases, and the height of the support base 73 is adjusted. The work of moving the upper support column in the vertical direction may become difficult.
Therefore, according to the fourth embodiment, it is possible to provide the walking support device 1 which is of great significance in that the height adjusting work of the support base 73 can be easily performed.

Further, one end of the slide member 98 of the connecting mechanism 96 is swingably attached to the upper end side of the mounting column 95, and one end of the pipe 97 of the connecting mechanism 96 is swingably attached to the lower end of the upper column 93. It may be configured.
That is, the connecting mechanism 96 includes a pipe 97 and a slide member 98 inserted into the pipe 97 via the other end opening 97b of the pipe 97, and one end thereof is swingably attached to the base 2. The other end is swingably attached to the lower end of the upper support column 93 so that it can be expanded and contracted, and the connecting mechanism 96 also expands and contracts as the cylinder 8 expands and contracts during standing operation support and seating operation support. It suffices if it is configured as follows.

Further, according to the walking support device 1 of the present invention, a left strut having one end swingably provided on the front left side of the base and a right strut having one end swingably provided on the front right side of the base. A support portion is provided on the other end side of the left strut and the right strut, and one end is swingably attached to the rear left side of the base so that the other end can swing to the left strut. Since it is equipped with an attached left cylinder and a right cylinder having one end swingably mounted on the rear right side of the base and the other end swingably mounted on the right strut, the standing motion support means and seating It is possible to provide a walking support device 1 having high motion certainty of the motion support means.

Further, the moving means 3 may be a moving means other than the wheels. For example, it may be a means of transportation such as a caster or a caterpillar provided with a ball instead of a wheel, and it may be a means of transportation configured so that braking can be applied.
