For example, the outer diameter of the front wheel 25 may be larger than the outer diameter of the rear wheel 30, the outer diameter of the front wheel 25 may be smaller than the outer diameter of the rear wheel 30, The outer diameter may be equal to the outer diameter of the rear wheel 30.

FIG. 3 is a plan view of an expanded form of the side frame 1. FIG. 4 is a plan view of the storage state of the side frame 1.
As shown in FIG. 3, the extending portion 16 is divided into two divided bodies 16A and 16B (extended portion divided bodies) at an intermediate position in the length direction (extending direction). The divided bodies 16A and 16B are called a front divided body 16A and a rear divided body 16B, respectively. The front divided body 16A and the rear divided body 16B are adjacent to each other in the extending direction. The rear split body 16B is a split body that is located closest to the extending direction of the extending portion 16 (that is, the rear side) among the two split bodies 16A and 16B.

  The form of the extending portion 16 in which the rear divided body 16B is not folded with respect to the front divided body 16A is referred to as an expanded form F1. 16Aa and 16Ba are inner surfaces of the front divided body 16A and the rear divided body 16B.

  The first folding mechanism 4 (folding mechanism) includes a first rotation connection section 42 having a hinge section 41. The hinge part 41 has a rotation axis along the Z direction. The first rotation connecting portion 42 rotatably connects the rear end of the front divided body 16A and the front end of the rear divided body 16B at the hinge portion 41. The hinge part 41 is provided on the inner surface side of the front divided body 16A and the rear divided body 16B.

  As shown in FIGS. 3 and 4, the rear split body 16B is rotatable inward. The term “inward” as used herein refers to a direction in which the rear divided bodies 16B, 16B of the pair of side frames 1, 1 approach each other. In FIG. 4, the rear divided body 16B is located at a position where the inner surface 16Ba faces the inner surface 16Aa of the front divided body 16A. As shown in FIG. 4, a form in which the rear divided body 16B is folded with respect to the front divided body 16A is referred to as a storage form F2. In the storage form F2, the angle θ between the inner surface 16Ba of the rear divided body 16B and the inner surface 16Aa of the front divided body 16A is, for example, 45 ° or less. In this way, in the walking support device 10, the size of the walking support device 10 in the left-right direction (Y direction) in the storage form F2 can be reduced because the rear split body 16B is rotatable inward. Therefore, the walking support device 10 is suitable for storage and transportation in the storage mode F2.

  As shown in FIGS. 1 and 2, the rod holding portion 13 is formed in a cylindrical shape, and is attached to the inner surface of the front divided body 16A along the Z direction.

The telescopic rod 31 has an outer shape conforming to the inner shape of the rod holding portion 13. The telescopic rod 31 is inserted into the rod holding part 13 and is movable with respect to the base frame 11 in the direction along the rod holding part 13 (the length direction of the telescopic rod 31). Since the telescopic rod 31 is movable with respect to the base frame 11, the extension length with respect to the base frame 11 can be adjusted. The expansion and contraction mechanism 14 may have a fixing mechanism (not shown) that positions the expansion and contraction rod 31 with respect to the rod holding unit 13 by tightening, fixing, or fitting unevenness.

  The height position of the upper frame 12 can be adjusted by adjusting the extension length of the telescopic rod 31 with respect to the base frame 11. For example, the upper frame 12 can switch between an extended form F3 indicated by a solid line in FIG. 5 and a storage form F4 indicated by a virtual line. In the expansion form F3, for example, the extension length of the telescopic rod 31 is the maximum, and the upper frame 12 is located at the highest position. In the storage form F4, the telescopic rod 31 is in the non-extended state, and the upper frame 12 is located at the lowest position. Since the extension length of the telescopic rod 31 can be adjusted, the height position of the upper frame 12 can be set arbitrarily.

  The upper frame 12 is provided to extend with respect to the base frame 11. The upper frame 12 includes a base 17 and an upper limb support 18. The base portion 17 is formed in a rod shape extending substantially forward from the upper end of the telescopic rod 31. The front part 17a of the base part 17 has a circular cross section orthogonal to the length direction. The front part 17a has a center axis C1 along the front-rear direction (X direction).

As shown in FIG. 6A, the upper limb support section 18 includes an extrapolation section 33 and a rod-shaped support section main body 34. The outer insertion portion 33 has a cylindrical shape having a central axis C2 along the front-rear direction (X direction). The central axis C1 coincides with the central axis C2. The extrapolation part 33 is extrapolated to the front part 17 a of the base part 17. As shown in FIG. 6B, the outer insertion portion 33 is rotatable around the center axes C1 and C2. The outer insertion portion 33 is rotatable inward. The term “inward” as used herein refers to a direction in which the upper limb support portions 18 of the pair of side frames 1 and 1 approach each other (see FIG. 4). The front portion 17a of the base portion 17 and the outer insertion portion 33 constitute a rotation mechanism 38 for rotating the upper limb support portion 18.

  As shown in FIG. 6A, the support portion main body 34 is formed in a substantially L-shape including an outwardly extending portion 35 and a main portion 36. The outwardly extending portion 35 extends in a direction perpendicular to the outer insertion portion 33 (upward in FIG. 6A). The main portion 36 extends rearward from the tip of the outwardly extending portion 35. The main portion 36 may be provided with a non-slip cover 37 made of a soft resin, rubber, or the like. The form of the upper limb support 18 in which the outward extension 35 faces upward is referred to as an expanded form F5. The form of the upper limb support 18 in which the outward extension 35 faces inward is referred to as a storage form F6.

  The upper limb support 18 supports the upper limb of the user standing between the base frames 11 of the side frames 1 and 1 (see FIGS. 12 and 13). The upper limb support 18 may function as, for example, a handle that the user grips with his / her hand, an armrest (armrest) that supports the user's elbow.

  As shown in FIG. 7, the two connection frames 3 are provided at the tip of the base upper portion 15A and the tip of the base lower portion 15B, respectively. Specifically, one connecting frame 3 is provided between the base upper portions 15A, 15A of the pair of side frames 1, 1, and connects the base upper portions 15A, 15A to each other. The other connecting frame 3 is provided between the lower base portions 15B, 15B of the pair of side frames 1, 1 and connects the lower base portions 15B, 15B to each other.

  As shown in FIGS. 7 to 9, the connection frame 3 is divided into four divided bodies 3A, 3B, 3C, and 3D (connected frame divided bodies) in the length direction. The divided bodies 3A, 3B, 3C, 3D are called a first divided body 3A, a second divided body 3B, a third divided body 3C, and a fourth divided body 3D, respectively. The divided bodies 3A, 3B, 3C, 3D are arranged side by side in this order from one end to the other end of the connection frame 3.

  As shown in FIG. 7, one end of the connection frame 3 (one end 3Aa of the first split body 3A) is provided on the inner surface of the base 15 of one of the side frames 1. The other end of the connecting frame 3 (the other end 3Db of the fourth divided body 3D) (see FIG. 8) is provided on the inner surface of the base 15 (specifically, the base upper part 15A and the base lower part 15B) of the other side frame 1. I have. Therefore, the connection frame 3 connects the base portions 15 of the side frames 1 and 1 to each other. A form in which the connecting frame 3 is not folded is referred to as an expanded form F7.

  The second folding mechanism 5 (folding mechanism) includes three second rotation connecting portions 52, 52, 52. The second rotation connecting portion 52 includes a hinge portion 51 having a rotation axis along the Z direction. The three second rotation connection parts 52, 52, 52 are referred to as second rotation connection parts 52A, 52B, 52C, respectively.

  As shown in FIG. 8, the second rotation connecting portion 52A rotatably connects the other end 3Ab of the first divided body 3A and one end 3Ba of the second divided body 3B at the hinge portion 51. The hinge portion 51 is provided on the rear side of the first divided body 3A and the second divided body 3B. As shown in FIG. 7, the second rotation connecting portion 52B rotatably connects the other end 3Bb of the second divided body 3B and one end 3Ca of the third divided body 3C at the hinge 51. The hinge portion 51 is provided on the front side of the second divided body 3B and the third divided body 3C. As shown in FIG. 8, the second rotation connecting portion 52C rotatably connects the other end 3Cb of the third divided body 3C and one end 3Da of the fourth divided body 3D at the hinge 51. The hinge portion 51 is provided on the rear surface side of the third divided body 3C and the fourth divided body 3D.

  As shown in FIG. 10, the second divided body 3B is rotatable rearward (extending direction side) with respect to the first divided body 3A. The third divided body 3C is rotatable rearward (extending direction side) with respect to the fourth divided body 3D. The connecting frame 3 shown in FIG. 10 is in a folded form. This form is called storage form F8.

In FIG. 10, the first divided body 3A and the fourth divided body 3D extend in the left-right direction (Y direction) as in the expanded form F7 (see FIG. 9). The second divided body 3B and the third divided body 3C extend in the front-rear direction (X direction). Specifically, the second divided body 3B extends rearward from one end 3Ba to the other end 3Bb, and the third divided body 3C extends rearward from the other end 3Cb to one end 3Ca. By setting the connecting frame 3 in such a form, the size of the connecting frame 3 in the left-right direction (Y direction) and the size in the front-rear direction (X direction) can be reduced. Therefore, the walking support device 10 is in a form suitable for storage and transportation.
The connection frame 3 can be made of, for example, a metal (aluminum alloy, steel, or the like), a carbon-based material, or the like.

  FIG. 11 is a perspective view of a storage form of the walking support device 10. In FIG. 11, since the base frame 11 is in the storage form F2, the size in the front-rear direction can be reduced. Since the upper frame 12 is in the storage form F4, the size in the height direction can be reduced. Since the upper limb support 18 is in the storage form F6, the size in the height direction can be reduced. Since the connecting frame 3 is in the storage form F8, the size in the left-right direction can be reduced.

  When the walking support device 10 is stored, transported by a vehicle or the like, the walking support device 10 can be configured as shown in FIG. Thereby, the walking support device 10 becomes compact not only in the left-right direction (Y direction) but also in the front-back direction (X direction) and the height direction (Z direction), which is suitable for storage and transportation.

  In the walking assistance device 10, since the extension 16 in the storage form F2 is in a folded state, the extension F16 (see FIGS. 1 and 2) can be easily obtained by extending the extension 16. . Similarly, since the connection frame 3 in the storage form F8 is in a folded state, the connection form 3 can be easily expanded to F7 (see FIGS. 1 and 2) by extending the connection frame 3. As described above, the walking support device 10 can easily perform the operation of shifting from the storage mode to the expansion mode. The walking support device 10 can easily perform an operation of shifting from the expansion mode to the storage mode.

  Even in the storage mode F8, the connecting frame 3 has a sufficient length (dimension in the Y direction), and the two side frames 1, 1 are separated. Therefore, the wheels 2 attached to the one side frame 1 and the wheels 2 attached to the other side frame 1 are sufficiently separated to the left and right. Therefore, the walking support device 10 can stably stand alone by the four wheels 2.

Next, a method of using the walking support device 10 will be described. As a user of the walking support device 10, a person who is unable to walk due to injury, illness, aging, or the like can be assumed.
FIG. 12 is a perspective view illustrating a first example of use of the walking support device 10. In this use example, the user U (U1) stands between the side frames 1, 1, and holds the upper limb support portions 18, 18 with both hands. In this usage example, the front-back direction of the walking support device 10 matches the front-back direction of the user U (U1). That is, the walking support device 10 is in a posture in which the connection frame 3 is positioned in front of the user U (U1).

  FIG. 13 is a perspective view showing a second example of use of the walking support device 10. As shown in FIG. In this usage example, the walking support device 10 is used in a posture opposite to that of the first usage example shown in FIG. That is, the walking support device 10 is in a posture in which the connecting frame 3 is located behind the user U (U2). In this use posture, the connection frame 3 does not hinder the walking support device 10 when the user U (U2) moves away from the walking support device 10 forward. Therefore, it becomes easy for the user U (U2) to move away from the walking support device 10 and move forward. This use posture is suitable, for example, when the user U (U2) is a young person.

  As shown in FIG. 12 and FIG. 13, the user U (U1, U2) stands between the side frames 1 and 1 of the walking assist device 10 while supporting the body by the upper limb support portion 18 of the upper frame 12, Walk in the desired direction. At this time, the walking support device 10 runs in the walking direction of the user U (U1, U2) by the wheels 2.

  Since the walking support device 10 includes the second folding mechanism 5 that folds the connection frame 3, unlike the case where the connection structure is a cross pipe, the connection structure (connection frame 3) in the storage mode F <b> 8 (see FIG. 10). The height dimension is the same as the expanded form F7 (see FIG. 9). Therefore, there are few restrictions on the design of the height setting of the walking support device 10. Therefore, for example, it is possible to provide a small-sized (that is, low in height) walking assistance device 10 suitable for a young person.

In the walking support device 10, since the structures of the first folding mechanism 4, the second folding mechanism 5, the expansion and contraction mechanism 14, and the rotation mechanism 38 are simple, the manufacturing cost can be reduced and the weight can be reduced.
Further, since the walking support device 10 uses the second folding mechanism 5 that folds the connecting frame 3, the user can move the frame F8 (see FIG. 10) from the expansion mode F7 (see FIG. 9) to the storage mode F8 (see FIG. 10). Accidents such as pinching of a finger with the like are unlikely to occur. Therefore, it is superior in terms of safety as compared with the case where the connecting structure is a cross pipe.
