Description

Detailed Description of the Invention

Technical Field: The present invention relates to a walking aid with a walking assistance function that can assist a person's walking and a mobility assistance function that allows a caregiver to move the person. Background Art: Walking aids for assisting people with leg disabilities have been well known. For example, one such walking aid is disclosed in Japanese Patent Laid-Open Publication No. 6-39007. The walking aid disclosed in this publication comprises an upper frame extending from the front of the user's body to both sides of the rear, a lower frame similarly extending from the front of the user's body to both sides of the rear, and a connecting frame connecting the upper and lower frames. Front wheels are attached to the front region of the lower frame, and rear wheels are attached to the rear region. The user stands in the space enclosed by the upper and lower frames and can walk while supporting their body with the upper frame. Users use such walking aids to travel to desired locations or for rehabilitation treatment. However, even if a user uses an ambulatory assist vehicle, they may become tired while walking due to leg disabilities, and may need to rest without using their legs. In this case, it is preferable for the user to be able to rest while using the ambulatory assist vehicle, considering the user's sense of security while walking. However, the ambulatory assist vehicle described in the above publication does not allow the user to rest without using their legs. It would be even more preferable if the ambulatory assist vehicle could be used to support the user's body when the user arrives at their destination and performs a desired action. In other words, it is preferable for the ambulatory assist vehicle to be able to support the user's body for purposes other than walking assistance. For example, it would be very convenient if the user uses the ambulatory assist vehicle to travel to a toilet and, upon arrival, can use the ambulatory assist vehicle as support for the user's body while using the toilet. In consideration of these issues, a first object of the present invention is to enable the user to rest without using their legs if they become tired while using the ambulatory assist vehicle. A second object of the present invention is to enable the user to use the ambulatory assist vehicle as support for the user upon arrival at the toilet. Disclosure of the Invention In order to achieve the first object described above, the first invention provides an ambulatory vehicle with a walking assistance function that can assist a person in walking and an assistance-movement function that allows a caregiver to move the person, the vehicle comprising a frame that extends around the body of a user of the ambulatory vehicle to support the body of the user when walking using the ambulatory vehicle, wheels attached to the frame, and a seat plate that can protrude from approximately the side of the user into the range of movement of the user's legs while walking, and the seat plate is configured to be removed from the range of movement of the user's legs while walking using the ambulatory vehicle. The second invention is the first invention in which the seat plate is pivotable about a predetermined axis, and by pivoting the seat plate, it can protrude into the range of movement of the user's legs while walking. The third invention is the second invention in which the predetermined axis is a horizontal axis. The fourth invention is the first invention in which the seat plate consists of a pair of seat plate portions,
These seat portions can protrude from both sides of the user into the range of movement of the user's legs while walking. In the fifth invention, the seat portion in the first invention can protrude from approximately to the side of the user and behind the user into the range of movement of the user's legs while walking. In the sixth invention, the height of the lowest frame among the frames located in front of the user in the first invention is higher than the height of the toilet seat, and the width between the two frames located approximately to the side of the user and in front of the user is wider than the width of the toilet. In the seventh invention, the seat portion in the sixth invention consists of a pair of seat portions,
These seat portions can protrude from both sides of the user into the range of motion of the user's legs when walking, and when these seat portions protrude into the range of motion of the user's legs when walking, they are at a position higher than the height of the toilet seat of the toilet, and there is a gap between these seat portions. In order to achieve the second object, an eighth invention provides an ambulatory vehicle for assisting a person's walking, which comprises a frame that extends around the body of the user to support the body of the user of the ambulatory vehicle when walking using the ambulatory vehicle, and wheels attached to the frame, and the height of the lowest frame located in front of the user is higher than the height of the toilet seat, and the width between the two frames located approximately to the side of the user and in front of the user is wider than the width of the toilet. In a ninth invention, the seat portion of the eighth invention is composed of a pair of seat portions,
These seat portions can protrude from both sides of the user into the range of leg movement of the user while walking, and when these seat portions protrude into the range of leg movement, they are positioned higher than the height of the toilet seat, and a gap exists between these seat portions. BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the illustrated embodiments. FIG. 1 shows a side view of one embodiment of the ambulatory support vehicle of the present invention, and FIG. 2 shows a front view of the embodiment shown in FIG. 1. For convenience of explanation, the right direction in FIG. 1 will be referred to as the "front," the left direction in FIG. 1 will be referred to as the "rear," the up direction in FIG. 1 will be referred to as the "upper," the down direction in FIG. 1 will be referred to as the "lower," and the left and right directions in FIG. 2 will be referred to as the "lateral." In FIG. 2, "upper" refers to the upward direction, and "lower" refers to the downward direction. As shown in FIG. 1, the ambulatory support vehicle of this embodiment includes a frame 1 that extends to surround the user. The frame 1 has an upper frame 2, a lower frame 3, and a connecting frame 4 for connecting the upper frame 2 and the lower frame 3. The upper frame 2 is roughly U-shaped, extending from the front region of the ambulatory assist vehicle toward both rear regions. The upper frame 2 is made of a hollow pipe with a rectangular cross section. Of course, the cross section of the upper frame 2 may be a shape other than a square, for example, a circular cross section. The periphery of the front portion 2f of the upper frame 2 and
Both sides of the upper frame 2 extending in the front-rear direction (hereinafter referred to as the upper frame side portions)
2s and peripheries thereof, elastic cushions 5 are attached. Also, handles 6 are removably attached to the rearmost portions of the upper frame side portions 2s. The illustrated handles 6 extend vertically upward, but the handles 6 can be attached facing in a different direction as required. On the other hand, the lower frame 3 is substantially U-shaped, extending from the front region of the ambulatory support vehicle toward both rear regions, similar to the upper frame 2, but its rear portion is bent downward and extends vertically downward. Therefore, in the following explanation, the portion that is horizontal with respect to the floor and extends from the front region of the ambulatory support vehicle toward both rear regions will be referred to as the lower frame horizontal portion 3h, and the portion that extends vertically downward will be referred to as the lower frame vertical portion 3h.
The lower frame vertical portion 3v is provided at its lower end with a wheel, so-called a free caster (hereinafter referred to as a rear wheel), 7, which can freely change the direction of travel in all directions. The lower frame vertical portion 3v also has a travel direction fixing means 8 at its lower end, which can fix the travel direction of the rear wheel 7 as needed. The travel direction fixing means 8 is attached to the lower portion of the lower frame vertical portion 3v along a predetermined horizontal axis A.
The lower frame 3 is a U-shaped frame member that is attached so as to be rotatable around the center h. When the frame member 8 is rotated downward, the rear wheel 7 fits into the frame member 8, and the traveling direction of the rear wheel 7 is fixed, for example, in the longitudinal direction. The lower frame 3 is made of a hollow pipe with a circular cross section, but it may be made of a hollow pipe with a cross section other than a circular cross section, for example, an elliptical cross section. The connecting frame 4 is made of an upper part (hereinafter, connecting frame upper part 4u) and a lower part (hereinafter, connecting frame lower part 4l). The connecting frame upper part 4u and the connecting frame lower part 4l are also made of hollow pipes with a circular cross section, but they may be made of a hollow pipe with a cross section other than a circular cross section, for example, an elliptical cross section. The upper end of the connecting frame upper part 4u is connected to the upper frame side part 2s.
The connecting frame upper portion 4u is connected to the approximately central portion of the connecting frame 4, and its upper end portion extends downward from the central portion of the connected upper frame side portion 2s. The outer diameter of the connecting frame upper portion 4u is smaller than the inner diameter of the connecting frame lower portion 4l, and the lower end of the connecting frame upper portion 4u is inserted into the connecting frame lower portion 4l. As will be described in detail below, the connecting frame upper portion 4u is slidably attached to the connecting frame lower portion 4l. The connecting frame lower portion 4l extends vertically downward from its upper end and bends horizontally forward near the floor surface. Therefore, in the following description, the portion of the connecting frame lower portion 4l extending vertically downward will be referred to as the vertical portion 4lv, and the portion extending horizontally forward will be referred to as the horizontal portion 4lh. Wheels, known as free casters (hereinafter referred to as front wheels) 9, which can freely change direction of travel in all directions, are attached to the lowermost, forward portion of the connecting frame 4 (i.e., the forwardmost portion of the horizontal portion 4lh of the connecting frame lower portion 4l). Additionally, a screw-type fastener 10 is attached near the upper end of the lower connecting frame portion 4l. When the fastener 10 is turned to loosen it, the upper connecting frame portion 4u can slide relative to the lower connecting frame portion 4l. On the other hand, when the fastener 10 is turned to tighten it, the screw tip of the fastener 10 locks the upper connecting frame portion 4u to the lower connecting frame portion 4l. Thus, the upper connecting frame portion 4u can be positioned at a desired position relative to the lower connecting frame portion 4l, and therefore the upper frame 2 can be positioned at a desired height above the floor. The vertical portion 4lv of the lower connecting frame portion 4l is connected to the approximate center of the horizontal portion 3h of the lower frame. Thus, the upper frame 2 and the lower frame 3 are connected to each other by the connecting frame 4. The portion where the lower frame 3 and the connecting frame 4 are connected is referred to as the frame connection portion. A pair of left and right seat panels 11p are attached to the portion of the horizontal portion 3h of the lower frame located rearward of this frame connection portion. Each seat panel portion 11p is pivotally attached to the lower frame horizontal portion 3h around a horizontal axis extending in the front-to-rear direction. Each seat panel portion 11p can pivot between a vertically upward position (hereinafter referred to as the vertical position) and a horizontally inward position (hereinafter referred to as the horizontal position), and can be positioned and maintained in either the vertical or horizontal position. As shown in FIG. 3 , when a pair of seat panel portions 11p are positioned and maintained in the horizontal position, they form a single seat panel 11 for the ambulatory support vehicle. The selection of either the vertical or horizontal position will be explained in detail later. To facilitate understanding of the seat panel portions, FIG. 3 only illustrates the seat panel portions and the lower frame to which they are attached. A pair of left and right foot panels 12 are attached to the front lower portion of the connecting frame 4, i.e., the horizontal portion 4lh of the connecting frame lower portion 4l. Each foot panel 12 is pivotally attached to the horizontal portion 4lh of the connecting frame lower portion 4l around a horizontal axis extending in the front-to-rear direction. Each foot plate 12 can pivot between a vertically upward extending state (hereinafter referred to as a vertical state) and a horizontally inward extending state (hereinafter referred to as a horizontal state).
The manually propelled vehicle can be positioned and held in either a vertical or horizontal position. The selection of either the vertical or horizontal position will be explained in detail later. The manually propelled vehicle of this embodiment is equipped with braking means 13 for braking its movement.
The braking means comprises a roughly U-shaped frame (hereinafter referred to as the U-shaped frame) 13u extending from the front region of the ambulatory assist vehicle to both rear regions thereof, a pair of left and right bars (hereinafter referred to as the vertical bars) 13v connected to the approximate center of the side portions of the U-shaped frame and extending vertically downward, a guide member 13g for slidably accommodating the vertical bars 13v and guiding their sliding movement, and a member (hereinafter referred to as the ground contact member) 13m attached to the lower end of the vertical bars 13v. The rearmost portion of the U-shaped frame 13u is pivotally attached to the side portion of the lower frame horizontal portion 3h. The front portion of the lower frame horizontal portion 3h is connected to the front portion of the lower frame horizontal portion 3h via a biasing means such as a spring 14. A locking plate 15 is attached to the front portion of the U-shaped frame 13u, which can lock onto the front portion of the U-shaped frame 13u and maintain the U-shaped frame 13u in an upper position.
The front part of the U-shaped frame 13u is pressed against the biasing force of the spring 14 to the locking plate 1.
When the engaging plate 15 is engaged with the floor 15, the ground contact member 13m is maintained at a position above the floor G. When the upper end of the engaging plate 15 is pulled backward and the engaging plate 15 is bent, the front portion of the U-shaped frame 13u is released from the engaging plate 15, and the U-shaped frame 13u is pulled downward by the biasing force of the spring 14, and the vertical bar 1
3v moves downward while being guided by the guide members 13g, allowing the ground-contacting members 13m to come into contact with the floor surface G. Thus, the ambulatory walker can be braked. This allows the brakes to be applied simultaneously on both sides of the ambulatory walker, improving braking performance. Furthermore, since the braking means of this embodiment does not directly apply braking force to the front wheels 9 or rear wheels 7, even if free casters are used as the front wheels 9 and rear wheels 7, the ambulatory walker can be braked using a braking means with a relatively simple mechanism, as in the present invention. In other words, while applying braking force directly to the free casters requires a more complex mechanism than the braking means of the present invention, the ambulatory walker can be braked using a relatively simple mechanism in the present invention. The advantages of the above-described ambulatory walker are listed below. In the above-described ambulatory walker, a person (hereinafter, "user") who intends to use the ambulatory walker stands in the space enclosed by the upper frame 2, lower frame 3, and connecting frame 4 and can use the ambulatory walker by leaning their body against the upper frame 2 or by placing their hands on the upper frame 2. This allows users with disabilities to walk or to undergo walking training. When walking using a walking aid like this, the seat part 11p
In other words, when walking using the walking aid, the seat portion 11p is positioned vertically from the area where the user's legs move for walking (hereinafter, the leg movement area).
In this manner, the user can walk without being hindered by the seat plate portion 11p. When the user becomes tired while walking using the walking aid and wants to rest, the seat plate portion 11p is pivoted and positioned horizontally, protruding into the leg movement area. Thus, the user can sit and rest on the seat plate 11 formed by the seat plate portion 11p. When the user is walking using the walking aid, the foot plates 12 are also positioned vertically. That is, the foot plates 12 are removed from the leg movement area. This allows the user to walk without being hindered by the foot plates 12. When the user sits on the seat plate 11 to rest, the foot plates 12 are positioned horizontally, protruding into the leg movement area. This allows the user to rest by placing their feet on the foot plates 12. Furthermore, the walking aid of the present invention has an assisted transportation function that allows a caregiver to move or transport the person. In other words, in an emergency situation where a person who cannot walk by themselves (hereinafter, "person requiring assistance") needs to be moved or transported to a destination, the person assisting the person (hereinafter, "assistant") can seat the person requiring assistance on the seat of the walking aid and push or pull the walking aid to transport the person requiring assistance to the destination. In the walking aid described above, there is no space between the lower front ends of the horizontal portions of the connecting frame lower section 4l, and they are separated from each other. Furthermore, the width of the horizontal portion of the connecting frame lower section 4l is wider than the width of a standard toilet T (shown by a chain line in Figures 1 and 2; hereinafter, simply referred to as the "toilet"), which is a type of toilet that is used while sitting. Furthermore, the height of the front portion 3f of the lower frame horizontal section 3h is higher than the height of the seat of a standard toilet T. This allows the user to pass the front portion of the lower frame horizontal section 3h over the seat of the toilet T when using the walking aid. Thus, the user can use the toilet while using the walking aid for support. Furthermore, in the above-described walker, the height of the seat portion 11p when it is extended horizontally into the leg movement area is higher than the height of the toilet seat of a standard toilet T. This allows the seat portion 11p to be positioned above the toilet T. Furthermore, as can be seen particularly from FIG. 3 , when the seat portion 11p is extended horizontally into the leg movement area, a space is formed between the seat portions 11p. Therefore, a user can use the toilet by sitting on the seat 11 with the seat portion 11p positioned above the toilet T. Of course, the seat 11 may be positioned even lower. In this case, for example, an additional frame extending parallel to the lower frame horizontal portion 3h may be attached to the lower frame vertical portion 3v and the vertical portion 4lv of the connecting frame lower portion 4l below the lower frame horizontal portion 3h, or an additional frame may be attached to the lower frame horizontal portion 3h so as to hang from it, and the seat portion 11a may be attached to this additional frame. This allows the seat surface to be positioned closer to the floor G. It is also advantageous to configure the upper frame 2 so that it can be easily replaced with an upper frame 2 of a different shape. In this configuration, the user can select the upper frame 2 of the most suitable shape according to their body type and connect it to the connecting frame 4 to use the walking aid. The configurations shown in Figures 4 to 11 can also be used as seat configurations that have the same advantages as those described above. In the embodiment shown in Figure 4, the lower frame 3
A pair of seat panel portions 11p are pivotally attached about a horizontal axis extending in the front-to-rear direction in front of the frame connection portion between the connecting frame 4 and the lower frame 3. In the embodiment shown in Figure 5, two pairs of seat panel portions 11p are pivotally attached about a horizontal axis extending in the front-to-rear direction behind the frame connection portion. In the embodiment shown in Figure 6, a pair of seat panel portions 11p are pivotally attached about a horizontal axis extending in the front-to-rear direction behind the frame connection portion, but when these seat panel portions 11p are positioned to extend horizontally inward, no space is formed between them. In the embodiment shown in Figure 7, a single seat panel 11 is pivotally attached about a horizontal axis extending in the front-to-rear direction to one of the horizontal portions of the lower frame 3 behind the frame connection portion. In the embodiment shown in Figure 8, a pair of seat panel portions 11p are pivotally attached about a horizontal axis extending in the front-to-rear direction in front of the frame connection portion, and a pair of seat panel portions 11p are attached about a horizontal axis extending in the front-to-rear direction behind the frame connection portion. In the embodiment shown in Fig. 9, a pair of seat panel portions 11p are attached rearward of the frame connecting portion, and these seat panel portions 11p are attached to the horizontal portion of the lower frame 3 so as to be pivotable about the vertical axis v. In the embodiment shown in Fig. 10, a pair of seat panel portions 11p are attached rearward of the frame connecting portion, and these seat panel portions 11p are fixed to the horizontal portion 3h of the lower frame, so that the horizontal portion 3h of the lower frame is pivotable about the vertical axis v.
In the embodiment shown in FIG. 1, a pair of seat plate portions 11p are provided in front of the frame connecting portion.
These seat panel parts 11p are attached to the lower frame horizontal part 3h so as to be pivotable about a vertical axis v. Furthermore, the handles 6 attached to the upper frame side parts 2s are suitable for the user to grasp with their hands when sitting on the seat panel 11 facing backward and moving around. Furthermore, as shown in Figure 12, these handles 6 may be made pivotable inward in the horizontal direction about a horizontal axis. In this way, the handles 6 can be pivoted inward in the horizontal direction and used as a backrest when the user is resting on the seat panel 11. Furthermore, the seat panel part 11p can be used for the following purposes in addition to being used as a seat panel 11 for resting. For example, rehabilitation can be carried out by moving forward using the legs while sitting on the seat panel 11. Furthermore, it is possible to stand up from the seat panel 11 or to use the seat panel 11 as a backrest.
1 can be used for rehabilitation of standing up. The seat panel 11 can also be used as a handrail when transferring from a prone position to an ambulatory walker. The ambulatory walker can also be used to move to the sink, and the seat panel 11 can be used to sit on while washing dishes after arriving at the sink. A back support plate can also be attached to the rear edge of each seat panel portion 11a so that it can pivot between a horizontal and a vertical position. In this case, when the back support plate is in the horizontal position, it rests on the upper wall surface of the seat panel portion 11a, and when the back support plate is in the vertical position, it extends upward from the rear edge of the seat panel portion 11a. When the back support plate is in the vertical position, it can be used as a backrest. Furthermore, by using the seat panel portion 11a as the seat panel 11 with the back support plate in the horizontal position, the seat surface for the user to sit on can be higher than the seat surface when the seat panel portion 11a is used as the seat panel 11 with the back support plate in the vertical position. Furthermore, if the entire walking aid is waterproofed, the walking aid of the present invention can also be used as an aid for the user when taking a shower. Furthermore, although aluminum may be used as the material for constructing the frame, since the user of the walking aid places their weight on the frame when walking, a relatively heavy frame is more stable and iron is preferable from the viewpoint of preventing the risk of the user falling. Of course, various materials can be used to construct the frame as needed, and the frame may also be made of plastic, for example.
