This allows the user to pull out the storage section to put items in and take items out of the storage section. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2024-63358 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, when a user puts or takes something in or out of the storage unit, it is conceivable that the user may do so while sitting in a chair or the like. In this case, the height position of the user's face will be close to the height position of the storage unit, and the peripheral wall of the storage unit (more specifically, the wall portion on the front side of the peripheral wall) may make it difficult to see inside the storage unit. This may make it difficult to put or take something in or out of the storage unit.

[0005] The present invention has been made in consideration of the above circumstances, and its main object is to provide a transport vehicle that allows a user to easily put items in and take items out of a storage section while sitting. [Means for solving the problem]

[0006] In order to solve the above problem, the mobile vehicle of the first invention is a mobile vehicle comprising a storage section that opens upward and can store objects, and a loading section that is located above the storage section and can place objects on, the storage section being capable of being pulled out from below the loading section, the storage section having a bottom plate and a peripheral wall section that rises upward from the peripheral edge of the bottom plate, and of the wall sections of the peripheral wall section that face the pulling-out direction, the wall section on the front side is the front side wall section, and the wall section on the rear side is the rear side wall section, and at least a portion of the front side wall section is a first low wall section whose height dimension is smaller than the height dimension of the rear side wall section.

[0007] According to the first aspect of the present invention, at least a portion of the front wall of the storage compartment is a first lower wall whose height is smaller than that of the rear wall. This allows the user to easily see inside the storage compartment when putting something in or taking something out of the storage compartment while sitting. This makes it easier for the user to put something in or take something out of the storage compartment while sitting.

[0008] The vehicle of the second invention is the vehicle of the first invention, wherein the entire front side wall portion is the first bottom wall portion.

[0009] According to the second aspect of the present invention, the entire front wall portion is the first bottom wall portion, which makes it easier to see inside the storage portion, making it easier for the user to put things in and take things out of the storage portion while sitting.

[0010] The third invention is a mobile vehicle according to the second invention, wherein the peripheral wall portion has a pair of side wall portions connecting the front wall portion and the rear wall portion, and at least the front side of the side wall portions in the pulling-out direction is a second low wall portion whose height dimension is smaller than the height dimension of the rear wall portion.

[0011] When a user is sitting and putting something in or taking something out of the storage compartment, it is conceivable that the user may be sitting at an angle to the direction in which the storage compartment is pulled out. In this regard, in the third invention, at least the front side of the side wall of the storage compartment is a second low wall portion whose height dimension is smaller than the height dimension of the rear wall portion. This makes it easier for the user to see inside the storage compartment when sitting at an angle to the direction in which the storage compartment is pulled out, thereby making it easier to put something in or take something out of the storage compartment.

[0012] The fourth invention is a transport vehicle according to the third invention, wherein the height dimension of the second lower wall portion is gradually reduced from the height dimension of the rear wall portion as it moves from the rear side to the front side in the withdrawal direction.

[0013] According to the fourth aspect of the present invention, the height of the second bottom wall portion is gradually reduced from the height of the rear wall portion as it moves from the rear side to the front side in the pull-out direction. This configuration in which at least the front side of the side wall portion is the second bottom wall portion can prevent items from falling out sideways from the storage portion.

[0014] The fifth invention is a transport vehicle according to the fourth invention, in which the entire side wall portion is the second low wall portion, and the height dimension of the second low wall portion gradually decreases from the height dimension of the rear wall portion to the height dimension of the first low wall portion.

[0015] According to the fifth aspect of the present invention, it is possible to further prevent objects from falling out sideways from the storage section.

[0016] The sixth invention is a mobile vehicle according to the fourth or fifth invention, in which the height dimension of the second bottom wall portion decreases from the rear side to the front side, and therefore the vertical distance between the second bottom wall portion and the storage portion increases from the rear side to the front side.

[0017] According to the sixth aspect of the present invention, the vertical separation distance between the second bottom wall portion and the mounting portion increases from the back side to the front side, which makes it easier to see inside the storage portion when sitting at an angle to the direction of withdrawal in a configuration in which the mounting portion is provided above the storage portion.

[0018] The seventh invention of the transport vehicle is any of the second to fifth inventions, in which the height dimension of the middle part of the first low wall portion in the wall width direction is smaller than that of other parts, so that a concave handle is formed in the middle part.

[0019] According to the seventh aspect of the present invention, the height of the middle portion of the first bottom wall in the wall width direction is smaller than that of other portions. In this case, the first bottom wall has a portion with a particularly small height, which makes it possible to prevent items from falling out of the storage compartment while making it easier to see inside the storage compartment. Furthermore, with the above configuration, a concave handle is formed in the middle portion of the first bottom wall. In this case, the storage compartment can be pulled out by holding the handle. This makes it easier to pull out the storage compartment while achieving the above-mentioned effects.

[0020] The vehicle of an eighth aspect of the present invention is any one of the first to fifth aspects of the present invention, wherein the height dimension of the first bottom wall portion is set in the range of 25 to 75% of the height dimension of the rear wall portion.

[0021] In order to prevent items from falling out when the storage unit is pulled out, it is desirable that the height of the first bottom wall be 25% or more of the height of the rear wall. On the other hand, in order to make it easy to see inside the storage unit while sitting, it is desirable that the height of the first bottom wall be 75% or less of the height of the rear wall. In this regard, in the eighth invention, the height of the first bottom wall is in the range of 25 to 75% of the height of the rear wall, so that it is possible to prevent items from falling out when the storage unit is pulled out and to make it easy to see inside the storage unit while sitting.

[0023] An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the mobility vehicle of the present invention is embodied as a walking vehicle for assisting elderly people and others in walking, and more specifically, as an indoor walking vehicle for use indoors. Figure 1 is a perspective view of the walking vehicle 10, seen obliquely from the rear. In the following description, the direction of movement of the walking vehicle 10 is defined as the front-to-rear direction, and the direction perpendicular to the front-to-rear direction is defined as the left-to-right direction.

[0024] As shown in Figure 1, the walker 10 comprises a pair of left and right frame sections 11 extending in the vertical direction, front wheels 12 and rear wheels 13 attached to the lower end of each frame section 11, and a connecting section 14 connecting the frame sections 11 together. Each frame section 11 is formed from a light metal such as aluminum. Each frame section 11 has a lower frame section 15 attached to its lower part and extending in the front-to-rear direction, and a vertical frame section 16 extending upward from the middle of the lower frame section 15. The front wheels 12 are attached to the front end of each lower frame section 15, and the rear wheels 13 are attached to the rear end.

[0025] An operating unit 21 is provided at the upper end of the vertical frame portion 16 of each frame section 11. The operating unit 21 has an attachment portion 22 attached to the upper end of the vertical frame portion 16, and a handle 23 and a brake lever 24 supported by the attachment portion 22. The handle 23 is the part that the user grips when moving the walker 10. The brake lever 24 is used to operate the brakes and is located below the handle 23. The handle 23 and the brake lever 24 are attached to the attachment portion 22 in a direction that extends rearward. The attachment portion 22 is formed with a handle 25 that can be gripped when lifting the walker 10 over steps, etc.

[0026] The walking frame 10 is provided with a storage section 31 capable of storing items, a tray 32 on which items can be placed, and a frame body 33 that supports the storage section 31 and tray 32. The configurations of the storage section 31, tray 32, and frame body 33 will be described below with reference to Figs. 2 to 5. Fig. 2 is a perspective view of the storage section 31 and tray 32 supported by the frame body 33, viewed obliquely from above. Fig. 3 is a perspective view of the frame body 33. Fig. 4 is an enlarged view of the area within frame A in Fig. 2, viewed from the rear. Fig. 5 is a perspective view showing the storage section 31 in Fig. 1 when pulled out rearward.

[0027] As shown in Fig. 2, the storage section 31 is formed in the shape of a flat rectangular box that is open at the top. The storage section 31 is formed, for example, from a synthetic resin. As the synthetic resin, a thermoplastic resin is preferable, and in particular, a general-purpose plastic such as polyethylene or polypropylene is preferable. Furthermore, the length of the storage section 31 in the front-to-rear direction is longer than the length in the left-to-right direction.

[0028] The tray 32 is formed in a rectangular shape (rectangular) and is disposed above the storage section 31. The tray 32 has a rectangular flat plate portion 32a and an edge portion 32b rising upward from the peripheral edge of the flat plate portion 32a. The tray 32 is formed, for example, from a synthetic resin. As the synthetic resin, a thermoplastic resin is preferable, and in particular, a general-purpose plastic such as polyethylene or polypropylene is preferable. The flat plate portion 32a of the tray 32 is formed to extend horizontally. Furthermore, the upper end of the edge portion 32b of the tray 32 extends outward to form a flange portion 32c. Furthermore, the length of the tray 32 in the front-to-rear direction is longer than the length in the left-to-right direction. The tray 32 and the storage section 31 have approximately the same size in a plan view. The tray 32 corresponds to the "placing section."

[0029] 2 and 3, the frame body 33 has a frame main body 35 and a pair of left and right rail portions 36 attached to the frame main body 35. The frame main body 35 has a pair of storage frames 38 that support the storage portion 31, and a tray frame 39 that supports the tray 32.

[0030] The pair of storage frames 38 are formed by bending metal rods or pipes into a U-shape and are spaced apart in the front-to-rear direction. Each storage frame 38 has a horizontal frame portion 38a extending in the left-to-right direction and a pair of diagonal frame portions 38b extending diagonally upward from both ends of the horizontal frame portion 38a. The diagonal frame portions 38b of each storage frame 38 extend diagonally so as to approach each other as they extend upward in a side view.

[0031] The tray frame 39 is formed from metal bars or pipes and has a rectangular ring shape in plan view. The tray frame 39 is disposed above each storage frame 38. The upper ends of the diagonal frame portions 38b of each storage frame 38 are fixed to the tray frame 39 by welding. A reinforcing frame 41 is bridged between the tray frame 39 and the diagonal frame portions 38b.

[0032] Plate-shaped hanging portions 42 extending downward from tray frame 39 are fixed to tray frame 39. Hanging portions 42 are disposed on both the left and right sides of tray frame 39. Each hanging portion 42 is disposed between diagonal frame portions 38b of each storage frame 38.

[0033] Each rail portion 36 extends in the front-to-rear direction and is provided so as to span the horizontal frame portion 38a of each storage frame 38. Each rail portion 36 has two rail components 43, 44 that extend in the front-to-rear direction. Each rail component 43, 44 is made of a long sheet metal member and is fixed to each horizontal frame portion 38a by welding.

[0034] 3 and 4, of the rail constituent parts 43, 44, the rail constituent part 43 is formed in a flat plate shape, and the rail constituent part 44 is bent in steps to form a Z-shaped cross section. A part of the rail constituent part 44 is disposed above the rail constituent part 43, and forms a rail groove 45 that is open laterally between the rail constituent part 43 and the rail constituent part 43.

[0035] A storage unit 31 is placed on each rail portion 36. The storage unit 31 is disposed between the diagonal frame portions 38b of the storage frame 38. A pair of left and right slide members 48 is provided on the bottom side of the storage unit 31. Each slide member 48 is formed in an elongated shape extending in the front-rear direction. Each slide member 48 is placed on the rail component portion 44 of the rail portion 36, and in this placed state, a portion of the slide member 48 is inserted into the rail groove 45 of the rail portion 36. In this case, as shown in FIG. 5 , each slide member 48 is slidable (guidable) in the front-rear direction along the rail portion 36, thereby allowing the storage unit 31 to slide in the front-rear direction. The storage unit 31 can be pulled out rearward from below the tray 32 by this sliding.

[0036] The tray 32 is placed on a tray frame 39 of the frame body 33. The tray 32 is disposed inside the tray frame 39, and its flange portion 32c is placed on the tray frame 39. This allows the tray 32 to be detachably mounted on the tray frame 39. The tray 32 is also disposed above the storage section 31 so as to cover the opening of the storage section 31.

[0037] Next, the installation configuration of the storage section 31, tray 32, and frame body 33 in the walking frame 10 will be described with reference to Fig. 6. Fig. 6 is a perspective view showing the storage section 31, tray 32, and frame body 33 removed from the walking frame 10.

[0038] 6, the frame body 33 is provided to span the vertical frame portions 16 of each frame portion 11 while supporting the storage portion 31 and the tray 32. In this case, the storage portion 31 is disposed between the vertical frame portions 16, more specifically, between the upper ends of the vertical frame portions 16.

[0039] A support portion 63 for supporting the frame body 33 is provided on the upper end side of each vertical frame portion 16. Each support portion 63 has an insertion hole 64 through which the vertical frame portion 16 is inserted, and is attached to the vertical frame portion 16 with the vertical frame portion 16 inserted into the insertion hole 64.

[0040] Each support portion 63 has a protruding portion 63a that protrudes inward in the left-right direction beyond the vertical frame portion 16. An insertion hole 65 is formed in the protruding portion 63a of each support portion 63, into which the hanging portion 42 of the frame body 33 is inserted. The insertion hole 65 is a hole that opens upward. The hanging portion 42 of the frame body 33 is inserted from above into the insertion hole 65 of each support portion 63. In this way, the frame body 33 is bridged across each support portion 63, and is therefore bridged across each vertical frame portion 16 via each support portion 63.

[0041] Each support portion 63 is provided with a hand-tightened fixing screw 67 that secures hanging portion 42 inserted into insertion hole 65. Hanging portion 42 is secured by this fixing screw 67, thereby fixing frame body 33 to each support portion 63. Furthermore, by loosening fixing screw 67, hanging portion 42 can be removed from insertion hole 65, allowing frame body 33 to be removed from each support portion 63. Frame body 33 is thus detachably attached to each support portion 63, and is in turn detachably attached to each vertical frame portion 16 via each support portion 63. Although not shown, walker 10 can be folded left and right by moving frame portions 11 closer to each other. When folding walker 10, frame body 33 is first removed from each support portion 63 and then folded.

[0042] Here, the walking frame 10 of this embodiment is characterized by the configuration of the storage section 31. The configuration of the storage section 31 will be described below with reference to Figures 7 and 8. Figure 7 (a) is a perspective view of the storage section 31, (b) is a front view of the storage section 31, and (c) is a side view of the storage section 31. Figure 8 is a side view showing the positional relationship between the storage section 31 and the tray 32.

[0043] 7(a) to 7(c) and 8, the storage section 31 has a rectangular, flat bottom plate 51 and a peripheral wall 52 rising upward from the peripheral edge of the bottom plate 51. The bottom plate 51 is formed to extend horizontally and is disposed parallel to the flat plate 32a of the tray 32. A rib 53 that protrudes downward is formed on the bottom surface of the bottom plate 51. The rib 53 extends in a square ring shape, and the above-mentioned slide member 48 is attached to the underside of the rib 53.

[0044] The peripheral wall 52 has a rectangular ring shape in a plan view. A flange 52a extending outward is formed at the upper end of the peripheral wall 52. The peripheral wall 52 also has a front wall 54 and a rear wall 55 that face each other in the front-rear direction, and a pair of side walls 56 that face each other in the left-right direction. Of the walls 54, 55, the front wall 54 is located on the front side in the front-rear direction, and the rear wall 55 is located on the rear side. In other words, the front wall 54 is located on the rear side in the pull-out direction of the storage section 31 (hereinafter simply referred to as the "rear side"), and the rear wall 55 is located on the front side in the pull-out direction (hereinafter simply referred to as the "front side"). Therefore, the front wall 54 corresponds to the "rear side wall," and the rear wall 55 corresponds to the "front side wall." Each side wall 56 is provided to connect the front wall 54 and the rear wall 55.

[0045] The front wall portion 54 has a constant height H1 over the entire width of the wall. The rear wall portion 55 has a height H2 that is smaller than the height H1 of the front wall portion 54. Specifically, the rear wall portion 55 has a height H2 that is smaller than the height H1 of the front wall portion 54 over the entire width of the wall (in other words, the left-right direction). Therefore, the entire rear wall portion 55 serves as a "first low wall portion." In this case, the upper end of the rear wall portion 55 is located lower than the upper end of the front wall portion 54 over the entire width of the wall.

[0046] The rear wall 55 has a first wall 55a at its middle portion in the wall width direction (more specifically, its center portion) that is smaller in height than the other portions. The rear wall 55 includes the first wall 55a and two second wall portions 55b provided on both sides of the first wall 55a. The length of the first wall 55a in the wall width direction is in the range of 1 / 4 to 1 / 2 of the length of the rear wall 55 in the wall width direction. Each second wall portion 55b corresponds to the "other portion" of the rear wall 55.

[0047] Since the middle part of the rear wall 55 is the first wall 55a, a concave handle 58 is formed in the middle part. The handle 58 is concave downward. When pulling out the storage section 31 rearward, it is possible to pull out the storage section 31 by holding the handle 58. The handle 58 corresponds to the "handle" described in the claims.

[0048] The height dimension H2 of the rear wall portion 55 is in the range of 25 to 75% of the height dimension H1 of the front wall portion 54. Specifically, the height dimension H2 of the rear wall portion 55 is in the range of 25 to 75% of the height dimension H1 of the front wall portion 54 across the entire area in the wall width direction, and more specifically is in the range of 40 to 60% of the height dimension H1 of the front wall portion 54. Furthermore, the height dimension H2 (hereinafter referred to as H2a) of the first wall portion 55a of the rear wall portion 55 is in the range of 2 / 3 to 4 / 5 of the height dimension H2 (hereinafter referred to as H2b) of each second wall portion 55b.

[0049] The height dimension H3 of each side wall portion 56 is smaller than the height dimension H1 of the front wall portion 54. More specifically, the height dimension H3 of each side wall portion 56 is smaller than the height dimension H1 of the front wall portion 54 across the entire area in the wall width direction (in other words, the front-to-rear direction). Therefore, each side wall portion 56 as a whole serves as a "second low wall portion." In this case, the upper end of each side wall portion 56 is located lower than the upper end of the front wall portion 54 across the entire area in the wall width direction.

[0050] The height dimension H3 of each side wall portion 56 gradually decreases from the front side (i.e., the back side) to the rear side (i.e., the near side). More specifically, the height dimension H3 of each side wall portion 56 gradually decreases from the front side to the rear side across the entire width of the wall. The height dimension H3 of each side wall portion 56 gradually decreases from the height dimension H1 of the front wall portion 54 to the height dimension H2 of the rear wall portion 55.

[0051] The upper end of each side wall 56 is an inclined end that slopes downward from the front to the rear. The upper end of each side wall 56 slopes linearly across the entire width of the side wall 56. The upper end of each side wall 56 is continuous with the upper end of the front wall 54 at its front end and with the upper end of the rear wall 55 at its rear end.

[0052] 8, the storage section 31 is spaced apart in the up-down direction from the tray 32 provided above it. In this case, the storage section 31 is spaced apart in the up-down direction from the tray 32 over the entire area in the front-to-rear direction. In addition, the height dimension H3 of the side wall 56 of the storage section 31 gradually decreases from the front to the rear, so that the vertical separation distance L between the side wall 56 and the tray 32 gradually increases from the front to the rear.

[0053] According to the configuration of this embodiment described above in detail, the following excellent effects can be obtained.

[0054] The rear wall 55 of the storage section 31 is a first lower wall section whose height dimension H2 is smaller than the height dimension H1 of the front wall 54. This allows the user to easily see inside the storage section 31 when putting something in or taking something out of the storage section 31 while sitting. This makes it easier for the user to put something in or take something out of the storage section 31 while sitting.

[0055] Furthermore, since the entire rear wall portion 55 is the first bottom wall portion, it is possible to make it easier to see inside the storage portion 31. Therefore, it is possible to put things in and take things out of the storage portion 31 more easily.

[0056] The rear side (in other words, the front side) of the side wall 56 of the storage section 31 forms a second low wall section whose height dimension H3 is smaller than the height dimension H1 of the front wall section 54. This makes it easier for the user to see inside the storage section 31 when sitting at an angle to the direction in which the storage section 31 is pulled out, thereby making it easier to put things in and take things out of the storage section 31.

[0057] The entire side wall 56 is the second bottom wall. The height H3 of the side wall 56 (in other words, the second bottom wall) gradually decreases from the front (rear side) to the rear (near side), from a height H1 of the front wall 54 to a height H2 of the rear wall 55. This configuration in which the side wall 56 has the second bottom wall can effectively prevent items from falling out of the storage compartment 31 to the side.

[0058] The vertical separation distance L between the side wall 56 and the tray 32 increases from the front (rear side) to the rear (near side). This makes it easier to see inside the storage section 31 when the tray 32 is provided above the storage section 31 and the user is sitting at an angle to the direction in which the tray is pulled out.

[0059] The height dimension of the middle portion of the rear wall 55 (first lower wall portion) in the wall width direction is smaller than that of other portions. In this case, since the rear wall 55 is partially provided with a portion with an especially small height dimension, it is possible to make the inside of the storage section 31 even easier to see while preventing items from falling out of the storage section 31. Furthermore, with the above configuration, a concave handle 58 is formed in the middle portion of the rear wall 55. In this case, the storage section 31 can be pulled out by holding the handle 58. This makes it possible to obtain the above-mentioned effects while making it easier to pull out the storage section 31.

[0060] In order to prevent items from falling out when the storage unit 31 is pulled out, it is desirable that the height H2 of the rear wall 55 (first bottom wall) be 25% or more of the height H1 of the front wall 54. On the other hand, in order to make it easy to see inside the storage unit 31 while sitting, it is desirable that the height H2 of the rear wall 55 be 75% or less of the height H1 of the front wall 54. In this regard, because the height H2 of the rear wall 55 is set in the range of 25 to 75% of the height H1 of the front wall 54, it is possible to make it easy to see inside the storage unit 31 while sitting, while preventing items from falling out when the storage unit 31 is pulled out.

[0061] The present invention is not limited to the above-described embodiment, and may be implemented, for example, as follows.

[0062] (1) In the above embodiment, the entire rear wall 55 is the first low wall having a height H2 smaller than the height H1 of the front wall 54. However, only a portion of the rear wall 55 may be the first low wall. For example, only the middle portion of the rear wall 55 in the wall width direction may be the first low wall.

[0063] (2) In the above embodiment, the height dimension of a portion of the rear wall portion 55 (first bottom wall portion) is smaller than that of the other portions. However, the height dimension of the entire rear wall portion 55 (first bottom wall portion) may be constant.

[0064] (3) In the above embodiment, the entire side wall 56 is the second low wall having a height H3 smaller than the height H1 of the front wall 54. However, only a portion of the rear (front) side of the side wall 56 may be the second low wall. For example, a configuration is conceivable in which the height of the front (rear) portion of the side wall 56 is the same as the height H1 of the front wall 54, and the height of the rear (front) portion is smaller than the height H1 of the front wall 54.

[0065] In the above configuration, the height dimension of the second bottom wall portion may be gradually reduced from the height dimension H1 of the front wall portion 54 as it moves from the rear side to the front side. Alternatively, the height dimension of the second bottom wall portion may be constant across the entire area in the wall width direction.
