Generally, this type of carriage is configured to be foldable so that nesting is possible. Specifically, between the vertical support columns 4 in the gate-shaped peripheral frame 3 of each side wall panel 2 is provided. An angle member 14 is installed, and the lower end of the vertical member 7 of the side wall panel 2 is fixed to the angle member 14. In addition, one of the left and right side wall panels 2 is connected to one vertical column 4 of the rear side wall panel 2 so that the side wall panel 2 can be folded horizontally so as to overlap the inner side of the rear side wall panel 2. 1 are attached to the lower side of the front end of the left and right side wall panels 2 and the lower side of the left and right sides of the rear side wall panel 2, and the loading platform 1 is a lower side angle member of the rear side wall panel 2. 14 is connected to the back side wall panel 2 so as to be foldable upward so that the side wall panel 2 on one side that can be folded is opened to the front side. The left and right side sides are assembled by placing them on the lower side angle members 14 of the left and right side wall panels 2.
[0010]
Of course, the transporting carriage of the present invention is not required to have the folding structure as described above. For example, a wheeled base frame that supports the loading platform 1 that is opened to the front is used. A rear side wall panel 2 is erected on the rear side of the frame, and a folding structure is adopted in which 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. It may be a transport cart that has been made, or may be a transport cart 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 (such as a round pipe material) into a gate shape, A columnar material (round pipe material or the like) having a diameter about half the diameter of the columnar material constituting the peripheral frame 3 is used. As shown in FIGS. 3 and 6A, the cross member 5 is composed of a vertical wall portion 9 and upper and lower horizontal wall portions 10a and 10b that are continuously bent at right angles from the upper and lower sides of the vertical wall portion 9 inward. The left and right vertical struts 4 of the peripheral frame 3 are made of steel having a longitudinal cross-sectional shape, and 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. It is built between.
[0012]
As shown in FIGS. 5 and 6A, the cross member 5 is formed with V-shaped cutout portions 11 on the upper and lower horizontal wall portions 10a and 10b in accordance with the arrangement position of the vertical member 7, and further, The wall portion 9 is formed with a recessed groove portion 12 formed by bending its constituent plate material inward along the length direction. The projecting surface 12a of the recessed groove portion 12 is in a position that substantially overlaps the rear end surface of the notch portion 11 in plan view, and each longitudinal member 7 is fitted to the notch portion 11 of the transverse member 5. The vertical member 7 is assembled by spot welding in a state where the vertical member 7 is pressed so as to abut against the protruding surface 12 of the recessed groove portion 12. That is, the recessed groove portion 12 serves to limit the amount of biting between the cross member 5 and the vertical member 7 due to pressurization when spot welding the cross member 5 and the vertical member 7, and the upper and lower horizontal wall portions 10 a and 10 b of the cross member 5. The notch 11 serves to regulate the position and orientation of the longitudinal member 7 relative to the transverse member 5.
[0013]
Each vertical member 7 is linear over the entire length, and as shown in FIG. 3, the center line 7c and the center line 6c of the upper end horizontal frame portion 6 of the peripheral frame 3 are substantially perpendicular to each other. It is arranged in parallel with the vertical support 4 of the frame 3. On the other hand, the cross member 5 is formed between the left and right vertical struts 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. In order to satisfy this condition, 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 cut portion 11 are set so that this condition is satisfied. A step corresponding to the difference in radius between the columnar member constituting the frame 3 and the columnar member constituting the longitudinal member 7 is generated between the outer surface 5a of the transverse member 5 and the outer surface 7a of the longitudinal member 7. Become.
[0014]
The display plate 8 disposed outside the vertical member 7 of the arbitrary side wall panel 2 is made of a rectangular metal plate (which may be a plastic plate) as shown in FIGS. 2, 3 and 4A. It is supported on the two vertical members 7 by a stopper 16 attached to the back of the four corners with rivets 15 or 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 thereof. The metal fitting 16 is fastened with a single rivet 15 or the like with both ends of a band-shaped metal plate wound around the vertical member 7 overlapped on the back surface of the display plate 8. The attachment structure with respect to the vertical member 7 is not limited to that of the illustrated example.
[0015]
As shown in FIGS. 3 and 4A, the display plate 8 attached as described above has a plate thickness that forms a columnar material constituting the peripheral frame 3 of the side wall panel 2 and a columnar material constituting the vertical member 7. Since it is sufficiently thinner than the difference in radius with the material, it protrudes outward from the outer surface 7a of the vertical member 7 by the thickness of the fastener 16, but enters inside sufficiently more than the outer surface 5a of the cross member 5. It is out. As shown in FIG. 3, the display plate 8 is placed on the cross member 5 (the upper surface of the upper side wall portion 10a).
[0016]
In addition, although the longitudinal cross-sectional shape of the recessed groove part 12 formed in the vertical wall part 9 of the cross member 5 was made into the trapezoid shape in which the flat protrusion surface 12a is formed in FIG. 6A, as shown to FIG. As shown in FIG. 6C, the included angle may be a mountain shape with an obtuse angle. 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 the upper and lower sides of the recessed groove portion 12, but only on one of the upper and lower sides of the recessed groove portion 12. It may be a cross-sectional shape in which a vertical flat plate portion remains, or a cross-sectional shape in which such a vertical flat plate portion does not remain at all, that is, the entire upper and lower ends of the vertical wall portion 9 are trapezoidal, mountain-shaped, The concave groove 12 having a cross-sectional shape that curves in an arc shape or the like may be used.
[0017]
【The invention's effect】
The present invention can be implemented and used as described above. According to the transport carriage of the present invention according to claim 1 or 3, the display plate attached to the side wall panel is the side wall. Although it is attached to the outside of the vertical member constituting the panel, the vertical member enters inside the outer surface of the transverse member constituting the side wall panel, and the display plate attached to the outside of the vertical member Since the outer display surface of the horizontal member is configured to enter the inner side of the outer surface of the cross member, the cross member serves as a bumper with respect to the display plate, and the transport carriage is moved. The cross member can prevent the display plate from slidingly contacting the surface of a building wall, pillar, fixture, or the like. Therefore, it is possible to prevent the display (printing) contents from being damaged due to damage to the outer surface (printing surface) of the display plate over a long period of time, and to maintain the display plate mounting effect well.
[0018]
In addition, the vertical member to which the display plate is attached needs to enter the inner side with respect to the outer surface of the horizontal member, but the position and orientation of the vertical member with respect to the horizontal member are formed on the upper and lower horizontal wall portions of the horizontal member. Further, it is possible to reliably perform the regulation as expected by fitting the vertical member to the pair of upper and lower cutout portions, and the side wall panel can be manufactured with high accuracy.
[0019]
Furthermore, according to the structure of this invention of Claim 1, even when it is a case where the manufacturing method which presses and welds a cross member and a vertical member mutually is applied to the inner side formed in the vertical wall part of a cross member. Thus, it is possible to surely regulate the fitting depth of the vertical member with respect to the transverse member, and it is possible to easily manufacture a highly accurate side wall panel. Moreover, 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 cross bar of the flat bar or the U-shaped cross section, and can effectively function as a bumper for the side wall panel. At the same time, even at the joint between the cross member and the vertical member, the vertical member enters the inner side (the back side) with respect to the surface of the cross member, and the section modulus of the joint portion between the two members is increased, thereby achieving strong bonding. Since it 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 second or third 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 prior art, thereby reducing the manufacturing cost. It can be reduced. Furthermore, according to the structure of Claim 4 , even if the attachment strength of the display plate to the vertical member is low, not only can the position of the display plate be securely held by the cross member, but also the display plate The bumper effect of the cross member can be enhanced.
