Modes for Carrying Out the Invention

[0018] Next, embodiments of the present invention will be described with reference to the attached drawings to facilitate understanding of the invention. Note that parts of the drawings that are not relevant to the explanation may be omitted.

[0019] [First Embodiment] The transport trolley 10 with protective members according to the first embodiment of the present invention, as shown in Figures 1 and 2, comprises a transport platform 20, casters 30, and protective members 40a to 40d, and is a flatbed trolley capable of transporting, for example, objects weighing 800 to 1000 kg. The objects to be transported are, for example, construction materials.

[0020] The following explanation will introduce a coordinate system consisting of the X, Y, and Z axes, which are substantially orthogonal to each other, and will be based on this coordinate system. The X axis is the axis that extends in a direction intersecting the longitudinal direction of the transport cart, the Y axis is the axis that extends in a direction intersecting the X axis when viewed from above, and the Z axis is the axis that intersects the X and Y axes and extends upward.

[0021] The transport platform 20 is a rectangular platform when viewed from above, on which the object to be transported is placed. The transport platform 20 has frames 210a to 210d, plate-shaped members 222, 224a to 224d, and socket members 230a to 230d provided at each corner (see Figure 2).

[0022] Frames 210a and 210c are rod-shaped and rectangular tubular members that extend in the X-axis direction, respectively. As shown in Figure 5B, a step is formed on the upper surface of frame 210a, with the outer height position being higher and the inner height position being lower than the outer height position. In other words, on the upper part of frame 210a (transport platform 20), an inner surface (an example of the first mounting part) 214a is formed on the side opposite to the outer surface 212a, with the direction of the normal facing in the opposite direction. Since frame 210c is formed in virtually the same way as frame 210a, a detailed explanation of it will be omitted.

[0023] Frames 210b and 210d are rod-shaped and rectangular tubular members that extend in the Y-axis direction. As shown in Figure 5C, a step is formed on the upper surface of frame 210b, with the outer height position being higher and the inner height position being lower than the outer height position. In other words, on the upper part of frame 210b (transport platform 20), an inner surface (an example of a second mounting part) 214b is formed on the side opposite to the outer surface 212b, with the direction of the normal facing in the opposite direction. Since frame 210d is formed in virtually the same way as frame 210b, a detailed explanation of it will be omitted.

[0024] As shown in Figure 2, the ends of frame 210a and frame 210b are fixed to each other via a socket member 230a, which will be described later, and the ends of frame 210b and frame 210c are fixed to each other via a socket member 230b. Furthermore, the ends of frame 210c and frame 210d are fixed to each other via socket member 230c, and the ends of frame 210d and frame 210a are fixed to each other via socket member 230d.

[0025] As shown in Figure 1, the plate-shaped members 222, 224a to 224d are plate-shaped members provided on the frames 210a to 210d, and together with the frames 210a to 210d and the socket members 230a to 230d, they form a mounting surface on which the transported object is placed. In other words, the upper surfaces of frames 210a to 210d, socket members 230a to 230d, and plate-like members 222, 224a to 224d are formed to be at the same height, serving as mounting surfaces on which the transported object is placed. It should be noted that "identical" here does not mean identical in a strict sense. Rather, "identical" here means that design and manufacturing tolerances are acceptable, and that they are "substantially identical" (the same applies hereafter).

[0026] As shown in Figure 2, the socket members (examples of members to be inserted) 230a to 230d each have a cylindrical portion 231, a first frame fixing portion 232a, 232b, and a second frame fixing portion 233a, 233b, respectively. Since the socket members 230a to 230d are substantially identical in shape, differing only in their mounting position on the transport table 20, only socket member 230a will be described below, and detailed explanations of the others will be omitted.

[0027] The cylindrical portion 231 is a cylindrical member with an insertion hole formed therethrough in the vertical direction. For example, a single pipe (an example of a rod-shaped member) P used in construction work is inserted into this insertion hole. The socket member 230a is provided with a projection (not shown) that protrudes inward from the insertion hole when viewed from above, and the lower end of the single pipe P rests on and contacts this projection, thereby supporting the single pipe P so that it extends upward from the transport platform 20.

[0028] The single pipes P inserted into each socket member 230a to 230d function as handles for the user to grip and move the transport cart 10 with protective members, or as fall prevention fences to prevent long transported objects that are longer than the distance between adjacent single pipes P from falling out.

[0029] The first frame fixing parts 232a and 232b are a pair of plate-like members that extend in the negative direction of the X-axis with a gap in the Y-axis direction from the cylindrical part, and can be fixed by sandwiching the end of the frame 210a between them. The second frame fixing parts 233a and 233b are a pair of plate-like members that extend in the negative direction of the Y-axis with a gap in the X-axis direction from the cylindrical part, and can be fixed by sandwiching the end of the frame 210b between them. Therefore, the socket member 230a can connect the end of frame 210a to the end of frame 210b.

[0030] The casters 30 are mounted at intervals on the underside of the transport platform 20, and for example, six casters are provided depending on the weight of the object being transported. The casters 30 are equipped with stoppers, and a pedal is provided to operate the stoppers.

[0031] The protective members 40a to 40d are resin components that are fitted onto the corners of the transport platform 20 from the outside, and they ensure a safe distance between the single pipe P held by the user and the wall (an example of an obstacle) in the area where the transport cart 10 with protective members is used. Note that obstacles are not limited to walls.

[0032] As shown in Figures 3A, 3B, and 4A to 4C, each protective member 40a to 40d has an integrally molded protruding portion 410, a lower projection 420, a first upper projection 430a, a second upper projection 430b, a first rib 440a, a second rib 440b, and a cushioning portion 450. Since the protective members 40a to 40d are substantially identical in shape, differing only in their mounting position on the transport platform 20, only protective member 40a will be described below, and detailed explanations of the others will be omitted.

[0033] As shown in Figures 1 and 2, the protruding portion 410 is a plate-shaped member that rests on the socket member 230a and the frames 210a and 210b, and extends outward from the corner of the transport platform 20.

[0034] As shown in Figure 3B, the lower projection 420 is a plate-shaped member extending downward from the lower surface of the overhang 410, with a claw formed at its tip. As shown in Figure 5A, this claw hooks onto the lower end of the socket member 230a from the outside. Therefore, a positioning structure (an example of a third positioning structure) is formed by the overhang 410 resting on the corner of the transport platform 20 and the lower projection 420 extending from the overhang 410, which hooks onto the lower end of the socket member 230a and is attached to the outside of the corner of the transport platform 20. This positioning structure sandwiches the transport platform 20, thereby positioning the protective member 40a in the vertical direction.

[0035] The first upper projection 430a is a claw provided on the overhang 410, as shown in Figure 4C, which protrudes downward from the inside of the overhang 410 and extends in the X-axis direction. This claw hooks onto the inner surface 214a formed on the frame 210a, as shown in Figure 5B. In Figure 4C, the dotted hatched areas indicate the portion where the protective member 40a rests on the socket member 230a and the frames 210a and 210b, which constitute part of the transport platform 20.

[0036] The second upper projection 430b is a claw provided on the overhang 410, as shown in Figure 4C, which protrudes downward from the inside of the overhang 410 and extends in the Y-axis direction. This claw hooks onto the inner surface 214b formed on the frame 210b, as shown in Figure 5C.

[0037] The first rib (an example of the first outer contact portion) 440a is a plurality of reinforcing members formed on the lower surface of the protruding portion 410, as shown in Figure 3B, and the inner side surface of the first rib 440a can contact the outer surface of the first frame fixing portion 232a (see Figure 5B) of the socket member 230a (the outer surface of the transport platform 20). Therefore, a positioning structure (an example of a first positioning part) is formed by a first upper projection 430a that catches on the inner surface 214a (see Figure 5B) formed on the frame 210a and a first rib 440a (see Figure 4C) that contacts the outer surface of the transport platform 20. This positioning structure then clamps a part of the transport platform 20, thereby positioning the protective member 40a in the Y-axis direction.

[0038] The second rib (an example of a second outer contact portion) 440b is a plurality of reinforcing members formed on the lower surface of the protruding portion 410, and the inner side surface of the second rib 440b can contact the outer surface of the second frame fixing portion 233a (see Figure 5C) of the socket member 230b (the outer surface of the transport platform 20). Therefore, a positioning structure (an example of a second positioning part) is formed by a second upper projection 430b that catches on the inner surface 214b (see Figure 5C) formed on the frame 210b, and a second rib 440b (see Figure 4C) that contacts the outer surface of the transport platform 20. This positioning structure clamps a part of the transport platform 20, thereby positioning the protective member 40a in the X-axis direction.

[0039] The buffer portion 450 is provided so as to bulge outward from the outer circumferential surfaces of the first rib 440a and the second rib 440b, and can mitigate the impact when the protective member 40a comes into contact with the wall. Therefore, the buffer portion 450 reduces the possibility of damage to the protective member 40a.

[0040] Next, we will explain how to use the protective members 40a to 40d. The protective transport trolley 10 can be moved, for example, by being placed on an elevator installed at a construction site. The elevator used at the construction site is, for example, 800 mm wide, and the width of the transport trolley 20 is set to be less than 800 mm.

[0041] However, the transport platform 20 (transport trolley 10 with protective members 40a to 40d) with protective members 40a to 40d attached has an overhang 410 that protrudes outward, resulting in a width exceeding 800 mm, which makes it impossible to place it on an elevator. Therefore, as shown below, even when the single pipe P is inserted into the transport trolley 10 with protective members, the protective members 40a to 40d can be easily attached and detached without using any tools.

[0042] To attach the protective member 40a, first, the claws of the lower projection 420 are hooked onto the lower end of the socket member 230a, and then the first upper projection 430a and the second upper projection 430b are simultaneously pushed towards the transport platform 20. Since the protective member 40a is molded from resin, a part of it flexes, causing the first upper projection 430a and the second upper projection 430b to move over the top surfaces of the frame 210a and frame 210b, respectively, and catch on the inner surfaces 214a and 214b. On the other hand, to remove the protective member 40a, simply follow the reverse procedure of the installation procedure described above. The same applies to protective members 40b to 40d.

[0043] Thus, according to the first embodiment of the transport trolley 10 with protective members, when an object to be transported is placed on the transport platform 20 and the user is moving it by gripping the left and right single pipes P with their left and right hands respectively, when the corners of the transport platform 20 collide with a wall, the protective members 40a to 40d make contact first, thus ensuring a distance between the single pipes P held by the user and the wall. Therefore, the possibility of the user's hand getting caught in the surrounding wall is reduced.

[0044] [Second Embodiment] Next, a transport trolley with protective members according to a second embodiment of the present invention will be described. Components identical to those in the transport trolley with protective members according to the first embodiment are denoted by the same reference numerals and their detailed descriptions are omitted.

[0045] As shown in Figure 6, the transport trolley with protective member according to this embodiment differs in the configuration of the lower projection of the protective member 50. The lower projection 520 of the protective member 50 has a support member 520a and a movable claw 520b.

[0046] The support member 520a is a plate-shaped member that extends downward from the lower surface of the overhang 410. The movable claw 520b can rotate around a rotation axis AX provided at the tip of the support member 520a, and the shape of the tip portion is substantially the same as the shape of the tip portion of the lower projection 420 according to the first embodiment.

[0047] Therefore, the protective member 50 is attached to the transport platform 20 by first hooking the first upper projection 430a and the second upper projection 430b onto the inner surface 214a of the frame 210a and the inner surface 214b of the frame 210b, and then rotating the movable claw 520b around the rotation axis AX to hook it onto the lower ends of the socket members 230a to 230d.

[0048] Thus, according to the second embodiment of the transport trolley with protective members, when an object to be transported is placed on the transport platform 20 and the user is moving it by gripping the left and right single pipes P with their left and right hands respectively, the protective member 50 is the first to make contact with the wall when the corner of the transport platform 20 collides with the wall, thus ensuring a distance between the single pipes P held by the user and the wall. Therefore, the possibility of the user's hand getting caught in the surrounding wall is reduced.

[0049] [Third Embodiment] Next, a transport trolley with protective members according to a third embodiment of the present invention will be described. Details common to the first embodiment may be omitted.

[0050] As shown in Figures 7 and 8, the transport trolley 60 with protective members according to this embodiment differs from the transport trolley 10 with protective members according to the first embodiment described above in that the transport platform 70 is further provided with cushioning members 750a to 750d, and the lower projections 920 of the protective members 90a to 90d are attached to these cushioning members 750a to 750d, respectively.

[0051] The protective transport trolley 60 comprises a transport platform 70, casters 30, and protective members 90a to 90d.

[0052] The transport platform 70 includes frames 710a to 710d, plate-shaped members 722, 724a to 724d, socket members 730a to 730d (see Figure 8) provided at each corner, and cushioning members 750a to 750d. The frames 710a to 710d, the plate-shaped members 722, 724a to 724d, and the socket members 730a to 730d are substantially identical in configuration to the corresponding members in the transport platform 20 according to the first embodiment. However, the shapes of each member differ slightly.

[0053] Since the cushioning members 750a to 750d are substantially identical in shape, only cushioning member 750a will be described below. The cushioning member 750a is attached so as to cover the outside of the socket member 730a when viewed from above, and is attached, for example, to the adjacent frames 710a and 710b on either side of the socket member 730a using bolts. The cushioning member 750a can mitigate the impact when the corner of the transport platform 70 comes into contact with a wall or the like when the protective member 90a is not attached.

[0054] Since the protective members 90a to 90d are substantially identical in shape, only protective member 90a will be described below. The protective member 90a is a resin component that is fitted onto the corner of the transport platform 70 from the outside, and is detachable with the single pipe P inserted. As shown in Figures 9A and 9B, the protective member 90a has a protruding portion 910, a lower projection 920, a first upper projection 930a, a second upper projection 930b, a first rib 940a, a second rib 940b, and a cushioning portion 950, which are integrally formed.

[0055] Of these, the lower projection 920 is a plate-shaped member that extends downward from the lower surface of the protruding portion 810, as shown in Figure 9B, and has a claw formed at its tip. As shown in Figure 10, this claw hooks onto a hole or recess formed on the lower end of the cushioning member 750a from the outside.

[0056] The first upper projection 930a is a claw provided on the protruding portion 910, which protrudes downward on the inside of the protruding portion 910 and extends in the X-axis direction. This claw hooks onto an inner surface or recess formed in the frame 710a. The first upper projection 930a may be configured to catch on the cushioning member 750a that constitutes the transport platform 70.

[0057] The second upper projection 930b is a claw provided on the protruding portion 910, which protrudes downward on the inside of the protruding portion 910 and extends in the Y-axis direction. This claw hooks onto an inner surface or recess formed in the frame 710b. The second upper projection 930b may be configured to catch on the cushioning member 750a that constitutes the transport platform 70.

[0058] Thus, according to the third embodiment of the transport trolley 60 with protective members, protective members 90a to 90d can be attached to a transport trolley equipped with cushioning members 750a to 750d without using any tools. Therefore, the protective members 90a to 90d can be easily attached and detached as needed.

[0059] Although embodiments of the present invention have been described above, the present invention is not limited to the above-described forms, and any changes to the conditions, etc., that do not depart from the gist of the invention are all within the scope of application of the present invention. In the above-described embodiment, the first upper projection and the second upper projection do not necessarily have to be attached so as to hook onto the inner surface formed as a step in the frame and the frame, respectively. For example, they may be attached so as to hook onto the inner surface formed as a recess in the transport platform. That is, each protective member is fitted from the outside of the transport platform, and the claws of the first upper projection and the claws of the second upper projection hook onto the first mounting portion and the second mounting portion formed on the inside of the transport platform when viewed from above, thereby positioning them in the X-axis and Y-axis directions. Furthermore, the rod-shaped member is not limited to a single pipe P, but can be any rod-shaped member that fits the insertion hole. [Explanation of symbols]
