  Here, the protective cover 14 is formed using the same aluminum as the frame member 13c to be protected. However, the protective cover 14 is basically formed thicker than the frame member 13c. Further, since the protective cover 14 is formed by bending an aluminum plate material, the protective cover 14 has a characteristic that the strength is higher than that of the extruded frame member 13c.

As shown in FIGS. 6 and 8, the planar portion 14a is a planar portion arranged so as to cover the concave portion 13e of the frame member 13c in a cross-sectional view along the horizontal direction, and is a front portion of the frame member 13c. It is fixed in close contact with a part.
As shown in FIGS. 9A to 9C, the first bent portion (fixed portion) 14b is configured so that the angle α1 of the end portion of the plane portion 14a is approximately 90 degrees in a cross-sectional view along the horizontal direction. It is bent so that it bends. And the 1st bending part 14b is arrange | positioned so that it may closely_contact | adhere with respect to the outer side surface of the frame member 13c which comprises the door 13 as shown in FIG. 6 and FIG. Further, as shown in FIG. 9B, a plurality of (four) fixing holes 14d arranged along the vertical direction are formed in the first bent portion 14b.

  As shown in FIGS. 9A to 9C, the second bent portion 14c is bent so that the angle β1 of the end portion of the plane portion 14a is bent to about 120 degrees in a cross-sectional view along the horizontal direction. It is bent. This angle β1 can be greater than 90 degrees and less than 180 degrees. And the 2nd bending part 14c is arrange | positioned in the state which opened the clearance gap with respect to the side surface inside the frame member 13c, as shown in FIG. 6 and FIG.

  Here, the 2nd bending part 14c is arrange | positioned in the open space compared with the 1st bending part 14b side. That is, as shown in FIG. 3 etc., adjacent members are disposed close to each other in the first bent portion 14b. Therefore, when the distribution wheel 10 comes into contact with an obstacle such as the handrail 32, the handrail 32 and the like hardly come into contact with the first bent portion 14b side, and toward the window portion 13b or the second bent portion 14c side. A contact is assumed.

Therefore, in the allocation vehicle 10 of the present embodiment, the second bent portion 14c, which may be in contact with an obstacle such as the handrail 32, is spaced from the frame member 13c to be protected by the protective cover 14. It is arranged.
Thereby, even when an obstacle such as the handrail 32 touches the second bent portion 14c directly or touching the window portion 13b and sliding on the surface of the window portion 13b, the second bent portion 14c is received. Damage to the frame member 13c can be reduced by preventing the external force from being directly transmitted to the inner frame member 13c or absorbing the collision energy by the second bent portion 14c being bent or deformed. . In addition, the external force applied from the obstacle such as the handrail 32 by the inclined surface of the second bent portion 14c is dispersed in a direction perpendicular to the inclined surface and a direction along the inclined surface. The force to bend or deform can be reduced.

As described above, since the window portion 13b is formed of a resin material such as polycarbonate having excellent impact resistance, damage due to contact with an obstacle such as the handrail 32 need not be considered. And
As shown in FIG. 9B, the fixing hole (fixing portion) 14d is a through hole formed perpendicular to the surface of the first bent portion 14b, and the fixing screw 21 is inserted therein. Then, as shown in FIGS. 5 and 7, when the fixing screw 21 is inserted into the fixing hole 14d, the fixing screw 21 is screwed into the screw hole 13d formed on the side surface of the frame member 13c. It is fixed to the frame member 13c.

  Similarly to the protective cover 14, the protective cover 15 constitutes a frame member 13 c of the open / close door 13 in order to suppress damage at the time of contact between an obstacle such as a handrail 32 (see FIG. 3) and the open / close door 13. It is attached to the member arrange | positioned among the members along the perpendicular direction. And the protective cover 15 is attached to the member by the side of a suspension provided with the rotating shaft 13a among the two members of the frame member 13c arrange | positioned along the perpendicular direction. Further, as shown in FIGS. 10A to 10C, the protective cover 15 is formed by bending a part of a flat plate material such as aluminum, and has a flat surface portion 15a and a first bent portion. It has a portion (fixed portion) 15b, a second bent portion 15c, and a fixing hole (fixed portion) 15d.

The protective cover 15 provided on the suspension side of the open / close door 13 has the same basic configuration as the protective cover 14 provided on the handle side (concave part 13e side). However, they differ from each other in that the dimension in the horizontal direction (width dimension) is small and the area of the plane part 15a is smaller than the area of the plane part 14a.
Here, like the protective cover 14, the protective cover 15 is formed using the same aluminum as the frame member 13c to be protected, and is basically formed thicker than the frame member 13c. Further, the protective cover 15 is formed by bending an aluminum plate material. For this reason, similarly to the protective cover 14, the protective cover 15 has a characteristic that the strength is higher than that of the extruded frame member 13c.

As shown in FIGS. 6 and 8, the flat portion 15 a is arranged so as to cover the front portion of the frame member 13 c in a cross-sectional view along the horizontal direction. And it fixes so that it may contact | adhere to a part of front part of the frame member 13c similarly to the plane part 14a.
As shown in FIG. 10C, the first bent portion (fixed portion) 15b has an angle α2 at the end of the flat portion 15a substantially equal to the first bent portion 14b in a cross-sectional view along the horizontal direction. It is bent so as to bend at 90 degrees. And the 1st bending part 15b is arrange | positioned so that it may closely_contact | adhere with respect to the outer side surface of the frame member 13c which comprises the door 13 as shown in FIG. 6 and FIG. Furthermore, as shown in FIG. 10B, the first bent portion 15b is formed with a plurality (four) of fixing holes 15d arranged along the vertical direction.

  As shown in FIG. 10C, the second bent portion 15c is bent so as to bend the angle β2 of the end portion of the flat portion 15a to about 120 degrees in a cross-sectional view along the horizontal direction. This angle β2 can be greater than 90 degrees and less than 180 degrees. And the 2nd bending part 15c is arrange | positioned in the state which opened the clearance gap with respect to the side surface inside the frame member 13c similarly to the 2nd bending part 14c, as shown in FIG.6 and FIG.8.

  Here, the 2nd bending part 15c is arrange | positioned in the open space compared with the 1st bending part 15b side. That is, as shown in FIG. 3 etc., the adjacent member is arrange | positioned closely in the 1st bending part 15b. Therefore, when the wheelbarrow 10 is in contact with an obstacle such as the handrail 32, the handrail 32 and the like hardly come into contact with the first bent portion 15b, and toward the window portion 13b or the second bent portion 15c. A contact is assumed.

Therefore, in the allocation vehicle 10 of the present embodiment, the second bent portion 15c that may be in contact with an obstacle such as the handrail 32 is spaced from the frame member 13c to be protected by the protective cover 15. It is arranged.
Thereby, even when an obstacle such as the handrail 32 touches the second bent portion 15c directly or touching the window portion 13b and sliding on the surface of the window portion 13b, the second bent portion 15c is received. Direct transmission of external force to the inner frame member 13c can be greatly reduced.

As described above, it is not necessary to consider the window portion 13b due to contact with an obstacle such as the handrail 32.
As shown in FIG. 10B, the fixing hole (fixing portion) 15d is a through hole formed perpendicular to the surface of the first bent portion 15b, and the fixing screw 21 is inserted therein. 6 and 8, the fixing screw 21 is inserted into the fixing hole 15d and screwed into the screw hole 13d formed on the side surface of the frame member 13c, so that the protective cover 15 is secured. It is fixed to the frame member 13c.

  As described above, the operation handle 16 is a handle portion that is gripped by the user when the trolley 10 is moved. As shown in FIG. 1 and the like, the operation handle 16 extends substantially horizontally along the side surface of the main body 11. It is attached. In addition, it is preferable that the height at which the operation handle 16 is attached is in a range of 900 mm to 1000 mm in which a user can easily apply force when pushing and pulling the layout vehicle 10.

Further, as shown in FIG. 3, the operation handle 16 is attached within the range R1 to which the above-described protective covers 14 and 15 are attached in the height direction.
As a result, by arranging the protective covers 14 and 15 so as to correspond to the height position of the operation handle 16 to which the force from the user is applied, the distribution vehicle 10 is placed at the height position where the operation handle 16 is installed. Even when it comes into contact with an obstacle such as the handrail 32, the frame member 13 c can be protected by the protective covers 14 and 15.

In the allocation vehicle 10 according to the present embodiment, as described above, the protective covers 14 and 15 are fixed to the side surface of the door 13, so that a fixing tool such as the fixing screw 21 is used and an obstacle such as a handrail 32 is provided. Do not expose to the contact area.
Thereby, for example, deformation / breakage in the frame member 13c of the open / close door 13 at the time of collision with an obstacle such as the handrail 32 installed in the corridor of the hospital can be effectively suppressed.

Further, as shown in FIG. 3, the protective covers 14 and 15 are attached so that the substantially center position in the height direction is substantially the same height as an obstacle such as the handrail 32. In addition, the height position of the handrail 32 installed in a hospital etc. is generally said to be in the range of 750 mm to 850 mm.
Therefore, in the allocation vehicle 10 of the present embodiment, the protective covers 14 and 15 are attached at positions centering on the installation height (750 mm to 850 mm) of the handrail 32.

Thereby, the part which may contact obstacles, such as the handrail 32, can be efficiently protected using the protective covers 14 and 15.
Moreover, the layout vehicle 10 of this embodiment is further provided with the adjustment mechanism 20 for adjusting the attachment position in the vertical direction (height direction) of the protective covers 14 and 15.
As shown in FIGS. 5 and 7, the adjustment mechanism 20 includes a screw hole 13 d formed on the side surface of the frame member 13 c and a plurality of fixing holes formed in the first bent portions 14 b and 15 b of the protective covers 14 and 15. 14d and 15d and the fixing screw 21 are comprised.

Thus, when the fixing screw 21 is screwed into the screw hole 13d formed on the frame member 13c side, the protective covers 14 and 15 for the frame member 13c depend on which fixing hole 14d and 15d the fixing screw 21 is inserted into. It is possible to adjust the height position where the is attached.
As a result, for example, after the distribution vehicle 10 is carried into a hospital or the like, the height position of the handrail 32 installed in the corridor of the hospital or the like is confirmed, and then the protective covers 14 and 15 are set to appropriate height positions. Can be attached.
