[0010]
Of course, the transporting cart of the present invention is not limited to the above-mentioned folding structure. For example, a base frame with wheels for supporting the loading platform 1 opened forward is used. A folding structure is employed in which the rear side wall panel 2 is erected on the rear side of the frame, and the left and right side wall panels 2 are connected to the left and right sides of the rear side wall panel 2 so as to be horizontally foldable inward. The transporting cart may be a folded transporting cart or a transporting cart having a structure that cannot be folded.
[0011]
The specific structure of each side wall panel 2 will be described with reference to FIGS. 2 to 6. The peripheral frame 3 is formed by bending a columnar material (a round pipe material or the like) into a gate shape. A cylindrical member (a round pipe member or the like) having a diameter of about half the diameter of the cylindrical member constituting the peripheral frame 3 is used. As shown in FIG. 3 and FIG. 6A, the cross member 5 includes a vertical wall portion 9 and upper and lower horizontal wall portions 10 a and 10 b which are bent and connected at right angles inward from upper and lower sides of the vertical wall portion 9. The left and right vertical columns 4 of the peripheral frame 3 are formed so that the outer surface 5 a (the outer surface of the vertical wall portion 9) is substantially flush with the outer surface 3 a of the peripheral frame 3. It is erected between them.

It is arranged in parallel with the vertical support 4 of the frame 3. On the other hand, the horizontal member 5 is provided between the left and right vertical columns 4 of the peripheral frame 3 so that the outer surface 5a (the outer surface of the vertical wall portion 9) is substantially flush with the outer surface 3a of the peripheral frame 3 as described above. Therefore, the width of the cross member 5 (the width of the upper and lower horizontal wall portions 10a and 10b) and the depth of the cutout portion 11 are set so that this condition is satisfied. A step corresponding to a radius difference between the columnar member forming the frame 3 and the columnar member forming the vertical member 7 is generated between the outer surface 5a of the horizontal member 5 and the outer surface 7a of the vertical member 7. Become.
[0014]
As shown in FIGS. 2, 3, and 4A, the display plate 8 disposed outside the vertical member 7 of the arbitrary side wall panel 2 is made of a rectangular metal plate (a plastic plate may be used). The four vertical members 7 are supported by fasteners 16 attached to the back surfaces of the four corners with rivets 15 and the like. The display plate 8 shown in FIG. 1 has a width in which one vertical member 7 is disposed on the center rear surface of the display plate 8 and the vertical members 7 are adjacent to the left and right sides, respectively. The metal fitting 16 is fastened with one rivet 15 or the like in a state where both ends of the band-shaped metal plate wound around the vertical member 7 are overlapped on the back surface of the display plate 8. The mounting structure for the vertical member 7 is not limited to the illustrated example.
[0015]
As shown in FIGS. 3 and 4A, the display plate 8 attached as described above has a plate thickness of a columnar member forming the peripheral frame 3 of the side wall panel 2 and a columnar member forming the vertical member 7. Since it is sufficiently thinner than the difference in radius from the member, it protrudes outward from the outer surface 7a of the vertical member 7 by the thickness of the stopper 16 but sufficiently enters inside the outer surface 5a of the horizontal member 5. In. As shown in FIG. 3, the display plate 8 is placed on the horizontal member 5 (the upper surface of the upper horizontal wall portion 10a).
[0016]
6A, the vertical cross-sectional shape of the recessed groove 12 formed in the vertical wall 9 of the cross member 5 is a trapezoid in which a flat protruding surface 12a is formed, but as shown in FIG. May be a mountain shape with a right angle, or as shown in FIG. 6C, the angle between the inside may be a mountain shape with an obtuse angle. Further, in each example shown in FIG. 6, the flat plate portion perpendicular to the vertical wall portion 9 of the cross member 5 has a cross-sectional shape that remains on both upper and lower sides of the concave groove portion 12, but only on one of the upper and lower sides of the concave groove portion 12. A cross-sectional shape in which a vertical flat plate portion remains may be used, or a cross-sectional shape in which such a vertical flat plate portion does not remain at all, that is, the entire portion between the upper and lower ends of the vertical wall portion 9 is trapezoidal inward, a mountain shape, The concave groove portion 12 having a cross-sectional shape that protrudes in an arc shape or the like may be used.
[0017]
【The invention's effect】
The present invention can be carried out and used as described above, and according to the transporting cart of the present invention, the display plate attached to the side wall panel is formed of the vertical member forming the side wall panel. Although it is attached to the outside, the vertical member enters inside the outer surface of the horizontal member constituting the side wall panel, and the external display surface of the display plate attached to the outside of the vertical member is the horizontal display member. Since the horizontal member serves as a bumper with respect to the display plate, the display plate is placed on the wall of the building when the transport cart is moved. The cross member can prevent sliding contact with the surface of a column, a column, or a fixture. Therefore, it is possible to suppress, over a long period of time, the outer surface (printing surface) of the display plate from being damaged and the display (printed) content becoming difficult to read, and the mounting effect of the display plate can be favorably maintained.
[0018]
According to the configuration of the second aspect, the vertical member to which the display plate is attached needs to be inserted inside the outer surface of the horizontal member, but the position and orientation of the vertical member with respect to the horizontal member are as follows. By fitting the vertical member into a pair of upper and lower cutouts formed in the upper and lower horizontal wall portions of the horizontal member, it is possible to reliably control as intended, and the side wall panel can be manufactured accurately.
[0019]
In this case, according to the configuration described in claim 3, even when the manufacturing method in which the horizontal member and the vertical member are pressed against each other and welded is applied, the horizontal member and the vertical member are formed inside the vertical wall portion of the horizontal member. The fitting depth of the vertical member to the horizontal member can be reliably restricted by the protruding concave groove portion, and a highly accurate side wall panel can be easily manufactured. Also, since the cross-sectional shape of the cross member is substantially Σ-shaped, the cross-sectional performance is improved and the bending strength is remarkably increased as compared with the flat bar or the cross member having the U-shaped cross section, and it can function effectively as a bumper of the side wall panel. At the same time, at the joint between the horizontal member and the vertical member, the vertical member enters the inside (rear side) with respect to the surface of the horizontal member, the section modulus of the joint between the two members increases, and a strong joint is formed. Since this can be realized, the strength of the side wall panel can be significantly increased as a whole.
[0020]
Further, according to the configuration of the fourth aspect, it is not necessary to bend the vicinity of the upper end of the vertical member inward and weld it to the upper end horizontal frame portion of the peripheral frame of the side wall panel as in the related art, thereby reducing manufacturing costs. I can do it. Further, according to the configuration of the fifth aspect, even if the mounting strength of the display plate with respect to the vertical member is low, not only can the position of the display plate be reliably held by the horizontal member, but also the position of the display plate with respect to the display plate can be reduced. The bumper effect of the crosspiece can be enhanced.
