DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The following describes in detail the split-type track trolley 1, 1' of the first and second embodiments of the present invention with reference to the attached drawings. Note that the first and second embodiments described below are merely examples of the present invention, and the present invention is not limited to the split-type track trolley 1, 1' of the first and second embodiments described below, and can be modified as appropriate within the scope of the technical concept of the present invention.

[0010] <Configuration of the split track trolley 1 of embodiment 1> The split type track trolley 1 of the embodiment 1 according to the present invention is configured as a split type, i.e., an assembly type, including a trolley front body 11 provided with left and right front wheels 11a, 11a that roll on left and right rails, a trolley rear body 12 provided with left and right rear wheels 12a, 12a1 that roll on left and right rails, a pair of left and right trolley middle side frames 13, 13 that detachably connect the trolley front body 11 and the trolley rear body 12 with a connecting pin 14, three floor plates 15 that are placed on the trolley front body 11 and the trolley rear body 12 connected by the trolley middle side frames 13, 13, and a passenger seat 16 on which a passenger sits. In addition, in FIG. 1, for convenience, the left side of the figure is described as the front side and the right side of the figure is the rear side, but it is of course possible for the left side of the figure to be the rear side and the right side of the figure to be the front side.

[0011] (Anterior toroidal body 11) As shown in Figures 1 to 6, the front body 11 of the trolley is the part that rotatably supports the front wheel axle 11b, which is provided on the left and right sides of the front wheels 11a, 11a that roll on left and right rails, respectively, and is composed of a pair of left and right front wheel bearing frames 11c, 11c that rotatably support the front wheel axle 11b on both the left and right sides, and a front body lateral frame 11d that is arranged parallel to the front wheel axle 11b and is connected to the sides of the pair of left and right front wheel bearing frames 11c, 11c by welding or the like.

[0012] The pair of left and right front wheel bearing frames 11c, 11c are each made of a hollow square tube, and as shown in Figure 5, etc., have pin holes 11c1, 11c1 into which the front connecting portions 13a, 13a of the trolley middle side frames 13, 13 are inserted for connection by the connecting pin 14, and their upper surfaces are provided with seat frame rear leg fitting protrusions 11c2, 11c2 that fit into the hollow portions at the lower ends of the rear legs 16b1, 16b1 of the seat support frame portions 16b of the occupant seat 16.

[0013] Of the pair of left and right front wheel bearing frames 11c, 11c, the lower front wheel bearing frame 11c in Figs. 1, 5 and 6 is provided with a front runaway prevention brake mechanism 11e, which will be described later.

[0014] The front body lateral frame 11d is composed of a hollow square tube or the like, and its upper surface is provided with a pair of plate lateral shift control protrusions 11d1, 11d1 spaced apart by the lateral width of the three floor plates 15 in order to control lateral shifting of the three floor plates 15 placed between the front body 11 and the rear body 12 of the trolley.

[0015] Therefore, the pair of plate lateral shift regulating protrusions 11d1, 11d1 allows the three floor plates 15 to be prevented from shifting in the lateral direction simply by placing them on the front body lateral frame 11d of the trolley front body 11 and the front body lateral frame 12d of the trolley rear body 12, which will be described later, thereby allowing easy assembly on site.

[0016] The front runaway prevention brake mechanism 11e is provided on the front wheel axle 11b as shown in Figures 7, 8, etc., and includes a front runaway prevention brake disc 11e1 having a cutout portion 11e11, a trapezoidal front brake piece 11e2 rotatably mounted via a brake piece pivot shaft 11e3 on the side of the front wheel bearing frame 11c on the upper and lower sides of Figures 1, 5, and 6, a brake control rod connection portion 11e4 using an L-shaped round pipe attached by welding or the like to the upper part of the front brake piece 11e2, and a brake control rod 11e5 that is inserted into the brake control rod connection portion 11e4 to rotate the front brake piece 11e2 around the brake piece pivot shaft 11e3.

[0017] Here, the cutout portion 11e11 of the front anti-runaway brake disc 11e1 is formed in an approximately radial direction of the front anti-runaway brake disc 11e1, that is, toward the front wheel axle 11b, which is the center of rotation of the front anti-runaway brake disc 11e1, and is composed of a braking end face 11e12 formed for applying the anti-runaway brake, and a brake piece raising end face 11e13 formed by bending from the braking end face 11e12 in a direction approximately perpendicular to the radial direction of the front anti-runaway brake disc 11e1 to raise the front brake piece 11e2.

[0018] Therefore, when the brake control rod 11e5 of the front side runaway prevention brake mechanism 11e is rotated clockwise to approach a vertical state as shown in Figure 7, the front brake piece 11e2 also rotates clockwise around the brake piece rotating shaft 11e3, and the brake piece tip 11e21 of the front brake piece 11e2 rises above the rear runaway prevention brake disk 12e1, so that the runaway prevention brake state is released and the front wheels 11a, 11a provided on both the left and right sides of the front wheel shaft 11b can rotate in either the clockwise or counterclockwise direction. Therefore, when the rear runaway prevention brake mechanism 12e provided on the trolley rear body 12 side, which will be described later, is also released from the runaway prevention brake state, the split track trolley 1 can run freely in either the forward or backward direction.

[0019] In contrast, when the brake control rod 11e5 of the front anti-runaway brake mechanism 11e is rotated counterclockwise to bring it closer to a horizontal state from a vertical state as shown in Figure 8, the front brake piece 11e2 also rotates counterclockwise around the brake piece pivot axis 11e3, and the brake piece tip portion 11e21 of the front brake piece 11e2 abuts against the cutout portion 11e11 of the front anti-runaway brake disc 11e1.

[0020] As a result, the front anti-runaway brake mechanism 11e on the front body 11 of the trolley is in the anti-runaway brake state, and when the front wheels 11a, 11a provided on both the left and right sides of the front wheel axle 11b rotate counterclockwise, the brake piece raising end face 11e13 of the cutout portion 11e11 of the front anti-runaway brake disc 11e1 comes into contact with the front brake piece 11e2, raising the front brake piece 11e2 and the brake control rod 11e5, allowing the wheels to rotate counterclockwise. However, when the wheels rotate clockwise, the brake piece tip portion 11e21 comes into contact with the braking end face 11e12, preventing them from rotating.

[0021] As a result, when the rear anti-runaway brake mechanism 12e described below, provided on the rear body 12 of the trolley, also enters the anti-runaway brake state, the split track trolley 1 will be unable to travel in either the forward or backward direction.

[0022] (Posterior trochord 12) The trolley rear body 12 is located on the opposite side of the trolley front body 11 via a pair of left and right trolley intermediate side frames 13, 13, as shown in Figures 1 to 5, and is configured symmetrically from the front to the rear with respect to the trolley front body 11, with rear wheels 12a, 12a1 rolling on left and right rails respectively, which rotatably support rear wheel axles 12b located on the left and right.

[0023] In other words, the rear body 12, like the front body 11, is composed of a pair of left and right rear wheel bearing frames 12c, 12c that rotatably support the rear wheel axle 12b on both the left and right sides, as shown in Figure 9, etc., and a rear body lateral frame 12d that is arranged parallel to the rear wheel axle 12b and is connected to the sides of the pair of left and right rear wheel bearing frames 12c, 12c by welding, etc.

[0024] The pair of left and right rear wheel bearing frames 12c, 12c are each made of a hollow square tube, and have pin holes 12c1, 12c1 into which the rear connection parts 13b, 13b (see Figure 5) of the trolley middle side frames 13, 13 are inserted for connection by a connecting pin 14.In addition, their upper surfaces are provided with seat frame rear leg fitting protrusions 12c2, 12c2, which, like the trolley front body 11, fit into the hollow parts at the lower ends of the rear legs 16b1, 16b1 of the seat support frame parts 16b of the occupant seat 16.

[0025] In addition, of the pair of left and right rear wheel bearing frames 12c, 12c, the lower rear wheel bearing frame 12c in Figure 9 is provided with a rear runaway prevention brake mechanism part 12e, similar to the front runaway prevention brake mechanism part 11e of the front body 11 of the trolley.

[0026] The rear body lateral frame 12d is composed of a hollow square tube, similar to the front body lateral frame 11d, and its upper surface is provided with a pair of plate lateral shift control protrusions 12d1, 12d1 spaced apart by the width of the three floor plates 15 in order to control lateral shifting of the three floor plates 15 placed between the front body 11 and the rear body 12 of the trolley.

[0027] Therefore, the pair of plate lateral shift control protrusions 11d1, 11d1 on the front body lateral frame 11d and the pair of plate lateral shift control protrusions 12d1, 12d1 on the rear body lateral frame 12d allow the three floor plates 15 to be prevented from shifting in the lateral direction simply by placing them on the front body lateral frame 11d of the trolley front body 11 and the front body lateral frame 12d of the trolley rear body 12, allowing easy assembly on site.

[0028] The rear runaway prevention brake mechanism 12e is provided on the rear wheel axle 12b, and includes a rear runaway prevention brake disc 12e1 having a cutout portion 12e11 similar to the front runaway prevention brake mechanism 11e, a trapezoidal rear brake piece 12e2 rotatably mounted on the side of the lower rear wheel bearing frame 12c in FIG. 1 via a brake piece pivot shaft 12e3, a brake control rod connecting portion 12e4 using an L-shaped round pipe attached by welding or the like to the upper portion of the rear brake piece 12e2, and a brake control rod 11e5 that is inserted into the brake control rod connecting portion 12e4 to rotate the rear brake piece 12e2 around the brake piece pivot shaft 12e3.

[0029] Here, the cutout portion 12e11 of the rear anti-runaway brake disc 12e1 is formed in an approximately radial direction of the rear anti-runaway brake disc 12e1, that is, toward the rear wheel axle 12b, which is the center of rotation of the rear anti-runaway brake disc 12e1, and is composed of a braking end face 12e12 formed for applying the anti-runaway brake, and a brake piece raising end face 12e13 formed by bending from the braking end face 12e12 in a direction approximately perpendicular to the radial direction of the rear anti-runaway brake disc 12e1 to raise the rear brake piece 12e2.

[0030] Therefore, when the brake control rod 12e5 is rotated counterclockwise to approach the vertical state as shown in Fig. 10, the rear brake piece 12e2 also rotates counterclockwise around the brake piece rotating shaft 12e3, and the brake piece tip 12e21 of the rear brake piece 12e2 rises above the front runaway prevention brake disk 11e2, so that the runaway prevention brake state is released, and the rear wheels 12a, 12a provided on both the left and right sides of the rear wheel axle 12b can rotate in either the clockwise or counterclockwise direction. As a result, by bringing the brake control rod 11e5 on the front side of the trolley 11 and the brake control rod 12e5 on the rear side of the track trolley 12 closer to the vertical state, both the front runaway prevention brake mechanism 11e and the rear runaway prevention brake mechanism 12e release the runaway prevention brake state, and the split track trolley 1 can run freely in either the forward or backward direction.

[0031] In contrast, when the brake control rod 12e5 is rotated clockwise as shown in FIG. 11 to move it from a vertical state toward a horizontal state, the rear brake piece 12e2 also rotates clockwise around the brake piece pivot axis 12e3, and the brake piece tip portion 12e21 of the rear brake piece 12e2 abuts against the cutout portion 12e11 of the rear anti-runaway brake disc 12e1.

[0032] Therefore, the rear runaway prevention brake mechanism 12e on the side of the trolley rear body 12 is in the runaway prevention brake state, and when the rear wheels 12a, 12a rotate clockwise, the brake piece raising end surface 12e13 of the cutout portion 12e11 of the rear runaway prevention brake disc 12e1 hits the rear brake piece 12e2, raising the rear brake piece 12e2 and the brake control rod 12e5, but still allowing the rear wheels 12a, 12a to rotate clockwise. On the other hand, when the rear wheels 12a, 12a rotate counterclockwise, the brake piece tip portion 12e21 of the rear brake piece 12e2 hits the brake end surface 12e12 of the rear runaway prevention brake disc 12e, so counterclockwise rotation is not possible.

[0033] As a result, when both the front anti-runaway brake mechanism 11e on the front body 11 of the trolley and the rear anti-runaway brake mechanism 12e on the rear body 12 of the trolley are in the anti-runaway brake state, the split track trolley 1 will be unable to run in either the forward or rearward direction.

[0034] (Toro mid-side frame 13,13) The pair of left and right trolley intermediate side frames 13, 13 are each composed of circular steel pipes of a predetermined length, and their front ends are provided with front connecting portions 13a, 13a which are inserted into the left and right front wheel bearing frames 11c, 11c of the trolley front body 11, 11 and connected by a connecting pin 14, while their rear ends are provided with rear connecting portions 13b, 13b which are inserted into the left and right front wheel bearing frames 12c, 12c of the trolley rear body 12 and connected by a connecting pin 14.

[0035] (Connecting pin 14) The connecting pin 14 is a well-known pin used to connect the left and right front wheel bearing frames 11c, 11c of the front body 11, 11 of the trolley, the left and right front wheel bearing frames 12c, 12c of the rear body 12 of the trolley, and the pair of left and right trolley intermediate side frames 13, 13.At its tip, a steel ball (not shown) is provided that moves in and out using a compression spring (not shown) built into the connecting pin 14, and the steel ball (not shown) is configured to automatically move in and out and lock when the connecting pin 14 is pushed or pulled.

[0036] (Floor plate 15) The floor plate 15 is a rectangular floor plate in plan view, constructed by providing convex portions in the longitudinal direction of the steel plate, as shown in Figures 12(a) to (d), and on the underside thereof are provided anti-slip protrusions 15a, 15a which protrude downward as shown in Figures 12(b) and (c) and abut against the sides of the front body lateral frame 11d and the rear body lateral frame 12d when placed on them, thereby preventing the floor plate 15 from slipping in the forward and backward directions of the split track trolley 1.

[0037] The floor plate 15 has an upper surface provided with a plurality of circular uneven anti-slip portions 15b.

[0038] (Passenger seat 16) As shown in Figures 13(a) and (b), the passenger seat 16 is composed of two seat sections 16a, 16a on which passengers can sit, a seat support frame section 16b that supports the two seat sections 16a, 16a with a gap between them in the left-right direction, and a handle guard 16c that is attached to the upper part of the seat support frame section 16b and outside the two seat sections 16a, 16a, and is grasped by the passenger.

[0039] The seat support frame portion 16b includes left and right rear leg portions 16b1 extending downward from the rear side (backrest side) of the occupant seat 16, left and right front leg portions 16b2 extending downward from the front side of the occupant seat 16, lateral connecting portions 16b3, 16b4 connecting the left and right rear leg portions 16b1 and front leg portions 16b2 from above and below, rear connecting portions 16b5, 16b6 connecting the left and right rear legs 16b1, 16b1 from above and below, and front connecting portions 16b7, 16b8, 16b9 connecting the left and right front legs 16b2, 16b2 in three stages at top, middle and bottom, respectively.

[0040] The lower ends of the rear legs 16b1, 16b1 are provided with mating recesses 16b11, 16b11 into which the seat frame front leg mating protrusions 11c2, 11c2 of the front body side frames 11c, 11c of the trolley front body 11 and the seat frame rear leg mating protrusions 12c2, 12c2 of the rear wheel bearing frames 12c, 12c of the trolley rear body 12 are inserted and fitted, as shown in Figure 2, etc.

[0041] In contrast, the lower ends of the front legs 16b2, 16b2 are respectively provided with side frame fitting recesses 16b21, 16b21 which abut against a pair of left and right trolley intermediate side frames 13, 13 that vertically connect the trolley front body 11 and the trolley rear body 12 as shown in Figures 2 and 13(a) and (b), and have pin holes 16b22, 16b22 that protrude downward from both sides of the trolley intermediate side frames 13, 13 and are pinned in place.

[0042] Therefore, the passenger seat 16 can be easily and removably attached to the split track trolley 1 constructed of the trolley front body 11, the trolley rear body 12, and the trolley middle side frames 13, 13 using only pins.

[0043] <Summary of the split-type track trolley 1 according to the first embodiment of the present invention> Therefore, the split track trolley 1 of embodiment 1 of the present invention is configured to be separable by connecting pins 14, i.e., to be assembled, and comprises a trolley front body 11 that rotatably supports a front wheel axle 11b with front wheels 11a, 11a on the left and right sides that roll on left and right rails, a trolley rear body 12 that rotatably supports a rear wheel axle 12b with rear wheels 12a, 12a1 on the left and right sides that roll on left and right rails, and a pair of left and right trolley intermediate side frames 13, 13 of a predetermined length that vertically detachably connect the left and right front wheel bearing frames 11c, 11c of the trolley front body 11 to the left and right rear wheel bearing frames 12c, 12c of the trolley rear body 12.

[0044] Therefore, in the split type track trolley 1 of embodiment 1 of the present invention, the front body 11, the rear body 12, and the middle side frames 13, 13 that make up the split type track trolley 1 can be removed and separated without adopting a folding mechanism, so that the overall structure of the split type track trolley 1 can be simplified and its strength can be improved.

[0045] In addition, in the split-type track trolley 1 of the embodiment 1 of the present invention, the front body lateral frame 11d of the trolley front body 11 and the rear body lateral frame 12d of the trolley rear body 12 are provided on both sides with lateral displacement control protrusions 11d1, 12d1 that regulate the lateral displacement of the floor plate 15, and the floor plate 15 is installed between the left and right lateral displacement control protrusions 11d1, 12d1 to prevent it from shifting sideways, while the front and rear of the floor plate 15 are provided with (b) Forward and backward shift control protrusions 15a, 15a are provided to control the forward and backward shift of the floor plate 15 relative to the front body lateral frame 11d of the front body 11 and the rear body lateral frame 12d of the trolley rear body 12, and the front and rear forward and backward shift control protrusions 15a, 15a abut against the front body lateral frame 11d of the trolley front body 11 and the rear body lateral frame 12d of the trolley rear body 12, thereby preventing the floor plate 15 from shifting forward and backward.

[0046] Therefore, according to the split type track trolley 1 of embodiment 1 of the present invention, the three floor plates 15 can be installed without shifting in the front-to-back and lateral directions simply by placing them on the trolley body constructed of the trolley front body 11, the trolley rear body 12, and the trolley middle side frames 13, 13, which also makes it possible to simplify the overall structure of the split type track trolley 1.

[0047] In addition, in the split type track trolley 1 of embodiment 1 of the present invention, the left and right front wheel bearing frames 11c, 11c of the trolley front body 11 and the left and right rear wheel bearing frames 12c, 12c of the trolley rear body 12, and the pair of left and right trolley intermediate side frames 13, 13 are each provided with pin holes 12c1, 12c1, and the pin holes 12c1, 12c1 of the left and right front wheel bearing frames 11c, 11c of the trolley front body 11 and the left and right rear wheel bearing frames 12c, 12c of the trolley rear body 12 are aligned with the pin holes 13c1, 13c1 of the pair of left and right trolley intermediate side frames 13, 13, and the connecting pin 14 is removably inserted, thereby making the split type track trolley 1 splittable.

[0048] Therefore, according to the split type track trolley 1 of embodiment 1 of the present invention, the connecting pin 14 makes it possible to easily connect the trolley front body 11, the trolley rear body 12, the trolley middle side frames 13, 13, etc., so that the overall structure of the split type track trolley 1 can be simplified in this respect as well.

[0049] In addition, in the split track trolley 1 of embodiment 1 of the present invention, the front wheel axle 11b of the trolley front body 11 is provided with a front anti-runaway brake mechanism part 11e having a front anti-runaway brake disc 11e1 and a front brake piece 11e2, a brake control rod connecting part 11e4, a brake control rod 11e5, etc., while the rear wheel axle 12b of the trolley rear body 12 is provided with a rear anti-runaway brake mechanism part 12e having a rear anti-runaway brake disc 12e1 and a rear brake piece 12e2, a brake control rod connecting part 12e4, a brake control rod 12e5, etc.

[0050] Therefore, according to the split track trolley 1 of embodiment 1 of the present invention, it is possible to easily apply and release the anti-runaway brake to the split track trolley 1 by simply raising and lowering the two brake control rods 11e5, 12e5, so that the overall structure of the split track trolley 1 can be simplified in this respect as well.

[0051] Embodiment 2. The split type track trolley 1' of the second embodiment is characterized in that it utilizes the split type track trolley 1 of the first embodiment described above and is configured to be capable of transporting a wheelchair 2 carrying an injured person, etc.

[0052] In other words, the split type track trolley 1' of the second embodiment is a split type track trolley 1 in which the above-mentioned trolley front body 11, trolley rear body 12, and trolley middle side frames 13, 13 are configured to be split by connecting pins 14, as shown in Figures 14 to 22 described later, and is configured to be able to transport wheelchairs 2, etc. by using two wheelchair transport boards 17, one auxiliary member 18, two walkways 19, and one floor plate 19'. Therefore, since the trolley front body 11, trolley rear body 12, trolley middle side frames 13, 13, connecting pins 14, etc. have the same configuration as the split type track trolley 1 of the first embodiment, their explanation will be omitted, and the newly added wheelchair transport board 17, auxiliary member 18, walkway 19, and floor plate 19' will be explained to explain the method of loading wheelchairs 2.

[0053] (Wheelchair transport board 17) 14(a) to (c) are respectively a plan view, a front view, and a side view of a wheelchair carrying board 17 constituting a split-type track trolley 1' according to a second embodiment of the present invention.

[0054] As shown in Figures 17 to 22 described below, the split track trolley 1' of embodiment 2 utilizes the split track trolley 1 of embodiment 1 and is configured to be able to transport a wheelchair 2 carrying an injured person, etc., and the wheelchair transport boards 17 are configured to be used in a set of two to carry the left and right wheels 2a, 2a of the wheelchair 2.

[0055] Specifically, the wheelchair transport board 17 is formed in a U-shape by a bottom plate 17a and a pair of side plates 17b, 17b rising from both the left and right sides of the bottom plate 17a, as shown in Figures 14(a) to (c).Since the wheels 21 of the wheelchair 2 are placed on the bottom plate 17a, the width of the bottom plate 17a is made greater than or equal to the width of the wheels 21 of the wheelchair 2.

[0056] Furthermore, on the back side (lower surface) of the bottom plate 17a, when the wheelchair transport board 17 is installed parallel to the traveling direction of the split track trolley 1', that is, perpendicular to the front wheel axle 11b of the trolley front body 11 and the rear wheel axle 12b of the trolley rear body 12, as shown in Figure 17 described below, it is placed on the front body lateral frame 11d of the trolley front body 11 and the rear body lateral frame 12d of the trolley rear body 12, respectively, and therefore first front-to-rear shift control protrusions 17a1, 17a1 are provided to prevent the wheelchair transport board 17 from shifting in the traveling direction (vertical direction) relative to the split track trolley 1'.

[0057] Therefore, when the wheelchair transport board 17 is installed on the split track trolley 1', it is placed on the upper surfaces of the front body lateral frame 11d of the trolley front body 11 and the rear body lateral frame 12d of the trolley rear body 12, as shown in Figures 17 and 18, and the first front-to-rear slippage control protrusions 17a1, 17a1 are located on the outside of the front body lateral frame 11d and the rear body lateral frame 12d, thereby providing an anti-slip function, so that the wheelchair transport board 17 can be securely installed on the split track trolley 1' without slipping off.

[0058] In addition, on the back side (underside) of the bottom plate 17a, as shown in Figure 20 described later, the wheelchair transport board 17 is placed on a pair of left and right trolley intermediate side frames 13, 13 so that it is horizontal to the split track trolley 1', i.e., parallel to the front wheel axle 11b of the trolley front body 11 and the rear wheel axle 12b of the trolley rear body 12, and second front-to-rear shift control protrusions 17a2, 17a2 are provided to prevent lateral shifting of the wheelchair transport board 17 relative to the split track trolley 1'.

[0059] Furthermore, when the wheelchair transport boards 17, 17 are placed on a floor plate 19' consisting only of the walkway body 19a without the wheelchair transport board connecting part 19b, which is placed in the center of the split track trolley 1' as shown in Figure 20, the second front-to-rear shift control protrusions 17a2, 17a2 are placed on the pair of left and right trolley middle side frames 13, 13, respectively, so the second front-to-rear shift control protrusions 17a2, 17a2 are each provided with a height adjustment bar 17a21, 17a2 lowered by the thickness of the floor plate 15.

[0060] Therefore, when the wheelchair transport board 17 is installed on the split track trolley 1', the height adjustment bar 17a21 of the second front-to-rear shift control protrusions 17a2, 17a2 comes into contact with the pair of left and right trolley middle side frames 13, 13, and the underside of the bottom plate 17a abuts on the upper surface of the floor plate 19', so that the wheelchair transport board 17 can be securely installed on the split track trolley 1' without any rattling.

[0061] Further, at both front and rear ends of the wheelchair carrying boards 17, 17, there are provided wheelchair carrying board engaging holes 17a3, 17a3 into which engaging projections 19b1, 19b1 of the wheelchair carrying board connecting parts 19b, 19b of the running board 19 are fitted.

[0062] (Auxiliary member 18) 15(a) to (c) are respectively a plan view, a front view, and a side view of an auxiliary member 18 constituting a split-type track trough 1' of embodiment 2 of the present invention.

[0063] As shown in Figures 17 to 22 described later, the split type track trolley 1' of the second embodiment is configured to use two wheelchair carrying boards 17 to transport a wheelchair 2 carrying an injured person, and the three floor plates 15 are removed and instead one floor plate 19' consisting of only the walkway body 19a with the wheelchair carrying board connecting part 19b omitted is used. Of course, instead of the floor plate 19' consisting of only the walkway body 19a, it is also possible to use the walkway 19 shown in Figure 16 which has the walkway body 19a and the wheelchair carrying board connecting part 19b.

[0064] Therefore, simply placing a single floor plate 19' on the split track trolley 1' of embodiment 2, which is composed of a trolley front body 11, a trolley rear body 12, and a pair of left and right trolley intermediate side frames 13, 13, may result in insufficient strength, so an auxiliary member 18 is provided to connect the pair of left and right trolley intermediate side frames 13, 13, as shown in Figures 17 and 20 described below.

[0065] The auxiliary member 18 has U-shaped trolley middle side frame fitting parts 18b, 18b on both sides of the auxiliary member main body 18a made of square tubes or the like, which are U-shaped and fit into the trolley middle side frames 13, 13, and is configured so that the auxiliary member 18 can be easily attached by fitting the trolley middle side frame fitting parts 18b, 18b from above the trolley middle side frames 13, 13, respectively. Therefore, the trolley main body, which is made up of the trolley front body 11, the trolley rear body 12, the pair of left and right trolley middle side frames 13, 13, and one floor plate 15, can be easily reinforced.

[0066] (Stepping Board 19) 16(a) and (b) are respectively a plan view and a front view of a running board 19 constituting a split-type track trolley 1' of embodiment 2 of the present invention.

[0067] The running board 19 is an auxiliary board used to load the wheelchair 2 onto the split track trolley 1' of embodiment 2 of the present invention, and is used in a set of two. As shown in Figures 16(a) and (b), one side of the running board main body 19a is provided with a wheelchair transport board connection portion 19b having an engagement protrusion 19b1 that fits into the wheelchair transport board engagement hole portion 17a3 on both sides of the wheelchair transport board 17.

[0068] In addition, on the back side of the walkway main body 19a, there are front-to-rear shift control protrusions 19a1, 19a1 that are located outside the front body lateral frame 11d and the rear body lateral frame 12d to prevent shifting when the floor plate 19' composed only of the walkway main body 19a as shown in Figure 14 is placed on the upper surfaces of the front body lateral frame 11d of the trolley front body 11 and the rear body lateral frame 12d of the trolley rear body 12.

[0069] Therefore, even when the step 19 is placed on the split track trolley 1' of embodiment 2 and moved on the rail R to the location where an injury has occurred, the step 19 can be reliably prevented from shifting in the forward / backward direction, thereby improving workability and safety, etc.

[0070] (Floor plate 19')

[0071] The floor plate 19' is composed of only the main body 19a of the walkway 19 shown in Fig. 14 as described above, and is a floor plate to be installed on the split-type track trolley 1' instead of the floor plate 15 of the first embodiment as shown in Fig. 17 and Fig. 20. Therefore, like the main body 19a of the walkway 19, it is provided with the front-rear slippage control protrusions 19a1, 19a1 that perform a slippage prevention function, but since the wheelchair transport board connecting part 19b is omitted, it is not used as a walkway.

[0072] However, since the floor plate 19' is the same as the walkway 19 except that the wheelchair transport board connection portion 19b is omitted, the walkway 19 may be provided in the center of the split track trolley 1' instead of the floor plate 19'.

[0073] <Method of using the split track trolley 1' according to embodiment 2 of the present invention> Next, a method of using the split track trolley 1' according to the second embodiment of the present invention will be described.

[0074] (When the running boards 19, 19 are installed between the rails R, R within the gauge) Figure 17 is a plan view showing a state in which the running boards 19, 19 constituting the split track trolley 1' of embodiment 2 of the present invention are installed at the rear (or front) of the split track trolley 1' so that the wheelchair 2 can be loaded onto the split track trolley 1' from within the gauge between the rails R, R, and Figure 18 is a front view showing this state.

[0075] In this case, in order to install the running boards 19,19 between the rails R,R within the gauge, in the split track trolley 1' of embodiment 2 of the present invention, the running boards 19,19 must be installed parallel to the forward and backward direction of the split track trolley 1' of embodiment 2 as shown in Figures 17 and 18, so the wheelchair transport boards 17,17 are installed so as to span between the front body lateral frame 11d of the trolley front body 11 and the rear body lateral frame 12d of the trolley rear body 12 so as to be continuous with the running boards 19,19.

[0076] The walkways 19,19 are connected to the wheelchair transport boards 17,17 and the engagement protrusions 19b1,19b1 of the wheelchair transport board connecting parts 19b,19b of each walkway 19,19 are fitted into the wheelchair transport board engagement holes 17a3,17a3 on both sides of each wheelchair transport board 17,17 to prevent the walkways 19,19 from falling off.

[0077] Then, as shown in Figures 17 and 18, the running boards 19, 19 can be attached to the wheelchair transport boards 17, 17 installed at the rear (or front) of the split track trolley 1' of embodiment 2 so that they do not fall off. As a result, as shown in Figure 19, a wheelchair 2 carrying an injured person or the like can be moved onto the split track trolley 1' using the running boards 19, 19 installed between the rails R, R within the gauge.

[0078] (When running boards 19, 19 are installed outside the gauge) Figure 20 is a plan view showing a state in which the running boards 19, 19 constituting the split track trolley 1' of embodiment 2 of the present invention are installed on the sides (lateral sides) of the split track trolley 1' so that a wheelchair 2 can be loaded onto the split track trolley 1' from outside the track gauge, and Figure 21 is a front view showing this state.

[0079] In this case, the running boards 19, 19 are installed on the outside of the rails R, R, which are outside the gauge, so in the split track trolley 1' of embodiment 2 of the present invention, the running boards 19, 19 are installed perpendicular to the forward and backward direction of the split track trolley 1' of embodiment 2, as shown in Figure 20, etc.

[0080] Therefore, the wheelchair transport boards 17, 17 must be installed so as to span over a pair of left and right trolley intermediate side frames 13, 13 that connect the trolley front body 11 and the trolley rear body 12 so as to be continuous with the running boards 19, 19 as shown in Figure 20. When installed in this manner, the wheelchair transport boards 17, 17 are placed on the floor plate 19', which is placed only one piece in the center of the split track trolley 1', as shown in Figure 20, with the second front-to-rear displacement control protrusions 17a2, 17a2 placed on the pair of left and right trolley intermediate side frames 13, 13, respectively, and the wheelchair transport board 17 can be securely installed on the split track trolley 1' without any rattling.

[0081] Also in this case, the running boards 19,19 are continuous with the wheelchair carrying boards 17,17, and the engaging projections 19b1,19b1 of each running board 19,19 are fitted into the wheelchair carrying board engaging holes 17a3,17a3 on both sides of each wheelchair carrying board 17,17 so as not to fall off.

[0082] Then, as shown in Figures 20 and 21, the steps 19, 19 can be attached to the wheelchair transport boards 17, 17 installed on the sides (transverse sides) of the split track trolley 1' of embodiment 2 so that they do not fall off.As a result, as shown in Figure 22, a wheelchair 2 carrying an injured person or the like can be moved onto the split track trolley 1' from the outside of the rails R, R, which are outside the gauge, using the steps 19, 19.

[0083] <Summary of the split-type track trolley 1 according to the first embodiment of the present invention> As described above, according to the split type track trolley 1' of embodiment 2 of the present invention, similar to the split type track trolley 1 of embodiment 1, the trolley front body 11 equipped with front wheels 11a, 11a, the trolley rear body 12 equipped with rear wheels 12a, 12a1, and a pair of left and right trolley intermediate side frames 13, 13 which detachably connect the trolley front body 11 and the trolley rear body 12 vertically are configured to be detachable by connecting pins 14 or the like, thereby simplifying the overall structure of the split type track trolley 1' and improving its strength.

[0084] In particular, in the split track trolley 1' of embodiment 2, the three floor plates 15 and the passenger seat 16 can be removed, and the wheelchair transport board 17, auxiliary member 18, running board 19 and floor plates 19', etc. can be configured to be removable, making it possible to transport a wheelchair 2 carrying an injured person, etc., thereby improving the usability of the split track trolley 1.

[0085] In addition, in the split track trolley 1' of embodiment 2, the two wheelchair transport boards 17, 17 are provided with first front-to-rear shift control protrusions 17a1, 17a1 and second front-to-rear shift control protrusions 17a2, 17a2 on the back side (lower surface side) of the bottom plate 17a, and the wheelchair transport boards 17, 17 are configured to be installed parallel to and perpendicular to the traveling direction of the split track trolley 1'. This makes it possible to move a wheelchair 2 carrying an injured person, etc., onto the split track trolley 1' from both the inside gauge, which is between the rails R, R, and the outside gauge, which is outside the rails R, R. This also improves the usability of the split track trolley 1. [Explanation of symbols]
