Description

[Technical Field]

[0001] The present invention relates to a transport vehicle. [Background technology]

[0002] With the industrialization of buildings such as houses and logistics warehouses, a construction method (e.g., panel construction method) has become common, in which roofs, walls, floors, etc. of buildings are manufactured as panels in factories, and various panels such as roof panels, wall panels, and floor panels are loaded onto the loading platform of a transport vehicle and transported to a construction site, where the panels are assembled together. Recently, efforts have been made to increase the size of panels manufactured in factories. Since larger panels reduce the number of assembly points at construction sites, increasing the size of panels is an important factor for improving work efficiency at construction sites.

[0003] When large panels are loaded onto a transport vehicle and transported from a shipping factory to a construction site, one or more large panels are generally loaded and transported in a horizontal position on the loading platform, but if the large panels are too wide (their height is longer than their width), and their width extends significantly beyond the left and right tailgates of the loading platform, there is a risk that they will exceed the vehicle width limit set forth in the Road Traffic Act (hereinafter sometimes referred to as the "Law"). Even if the width limit is not exceeded, if a transport vehicle is driven on a public road with its cargo significantly extending to the sides of the loading platform, it will undoubtedly give an intimidating and dangerous impression to third parties who see the transport vehicle, such as drivers of other vehicles also driving on the public road and pedestrians passing on the sidewalk.

[0004] Therefore, instead of laying the large panel on the loading platform, one method of transporting it is to place it upright on the loading platform. However, even if the large panel is placed upright with its width oriented vertically, if the panel is over 3m wide, and the height from the ground to the loading platform is assumed to be approximately 1m, the height from the ground to the top of the upright large panel will exceed 3.8m, which poses a risk of exceeding the height limit under the Road Traffic Act.

[0005] Considering the current situation where there is a considerable demand for transporting large panels that are 3m or more wide (and naturally longer in height) to construction sites, there is a need for a transport vehicle that can transport large panels to construction sites in compliance with the law without giving third parties an impression of intimidation or danger.

[0006] Here, Patent Document 1 proposes large panels that can be efficiently lined up and loaded onto the bed of a truck. These large panels are used to form the walls, roofs, floors, etc. of buildings, and when the length of the long side of the bed of the truck that transports the large panels is K, the length of the long side of the large panel is L, and the number of large panels lined up and loaded along the length of the bed is n, the length L of the long side of the large panel is set to satisfy the relationship K / 1.2n≦L≦K / n. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-129700 Summary of the Invention [Problem to be solved by the invention]

[0008] The large panels described in Patent Document 1 merely specify the dimensions of the large panels, and do not propose a transport vehicle that enables the transport of large panels of various sizes to construction sites while complying with the law.

[0009] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a transport vehicle that can transport cargo, including as wide a range of large panels as possible, to a construction site while complying with legal height and width restrictions without giving third parties an impression of intimidation or danger. [Means for solving the problem]

[0010] In order to achieve the above object, one aspect of the transport vehicle according to the present invention is: A transport vehicle having a cabin and a loading platform with tailgates for transporting luggage, The width of the cabin is wider than the width of the loading platform, The luggage is placed upright outside the tailgate and fixed to the loading platform with its lower end lowered to a position lower than the loading platform, and the luggage is transported in a state where it is accommodated within the step area between the cabin and the loading platform when viewed from above.

[0011] According to this aspect, instead of loading the cargo onto the loading platform, the cargo is set upright outside the tailgate with its bottom lowered to a position lower than the loading platform and secured to the loading platform. This makes it possible to transport large panels with dimensions that satisfy the legal height limit from a position lower than the loading platform (for example, slightly higher than the ground) and the height (width) of the loading platform tailgate, even for large panels with long widths and lengths. This makes it possible to transport a wide range of large panels and improves the efficiency of assembling large panels at construction sites.

[0012] In addition, the cabin is wider than the loading platform, and the luggage is secured to the loading platform and transported within the step area between the cabin and loading platform in a plan view. This prevents the luggage from protruding outward from the cabin, thereby preventing a sense of intimidation or danger from being felt by a third party who sees a transport vehicle transporting luggage secured to the outside of the loading platform. For example, a third party seeing an oncoming transport vehicle will not feel intimidated because the luggage is hidden within the width of the cabin. On the other hand, a third party looking at the transport vehicle from behind will similarly not feel intimidated because the luggage is located behind the width of the cabin.

[0013] Here, the dimensions of the protruding rod-like body are set so that when the protruding rod-like body is installed on the side of the cabin, the width of the cabin including the protruding rod-like body complies with the legal width limit of 2.5 m. Suitable cargo to be transported by the transport vehicle of this embodiment includes various panels that are long in both height and width, such as roof panels, wall panels, and floor panels, as well as large window glass. Specific examples of cargo dimensions include large cargo that is rectangular in plan view and has a height (or width) that is equal to the length of the bed tailgate (for example, 4 m or more) and a height limit of 3.8 m or more for public roads (when secured in a position lowered as close to the ground as possible), respectively.

[0014] Another aspect of the transport vehicle according to the present invention is A protruding rod-like body that widens the width of the cabin is attached to the rear of the side of the cabin.

[0015] According to this aspect, by attaching a protruding rod-shaped body that widens the width of the cabin to the rear of the side of the cabin, the width of a portion of the cabin can be easily widened without changing the structure of the cabin, and the protruding rod-shaped body can prevent luggage located behind the cabin from protruding to the side. Here, depending on the manner in which luggage is fixed to the outside of the left and right tailgates, the protruding rod-shaped body may be attached to the left and right side of the cabin, or to either the left or right side.

[0016] In another aspect of the transport vehicle according to the present invention, The protruding rod-shaped body is characterized by having a fixed piece that is fixed to the cabin, and a protruding piece that extends laterally from the fixed piece and has a tip that is curved or bent rearward toward the loading platform.

[0017] According to this aspect, the protruding rod-shaped body has a relatively simple configuration, with a fixed piece that is fixed to the cabin and a protruding piece that protrudes to the side and has a tip that is curved or bent toward the rear cargo bed, so the width of the cabin can be expanded as desired with a protruding rod-shaped body that can be manufactured at low cost.In addition, since the body is composed of a fixed piece and a protruding piece, and each piece only needs to have rigidity (thickness) that can withstand wind pressure and the like while driving, the member as a whole is lightweight, and there is no problem with the weight load it places on the vehicle body.

[0018] Furthermore, since the protruding pieces have a smooth outer shape that is curved or bent toward the loading platform, the air resistance of the protruding rod-shaped body is also reduced, and the protruding rod-shaped body and the luggage standing behind it appear to be one whole, creating a transport vehicle that is even less intimidating.

[0019] In another aspect of the transport vehicle according to the present invention, A fixing jig for fixing the luggage is provided on the gate, The fixing jig is A U-shaped straddling piece that straddles the top of the gate, A load bearing piece that is bent from one end of the straddling piece and extends to the loading platform, and a counterweight is loaded thereon. A plurality of first bolt holes are opened in the longitudinal direction of the straddling piece, The luggage is placed on the luggage receiving piece, the multiple first bolt holes of the overpass piece and the second bolt holes corresponding to each of the first bolt holes in the luggage are connected to form multiple communicating holes, the luggage is fixed to the fixing jig by screwing a bolt into each communicating hole, and the counterweight is loaded on the load-bearing piece, thereby maintaining the luggage in an upright position.

[0020] According to this aspect, the load-carrying piece of the fixture installed on the loading platform is fixed on the loading platform with a counterweight, while the load is bolted at multiple locations on the straddling piece of the fixture that straddles the gate. This allows the load to be fixed in an upright position simply by installing a simple fixture, without the need for special fastening means on the loading platform of the transport vehicle. Because the load is fixed to the straddling piece with multiple vertical bolts, the stability of the upright position of the load is ensured and the load is prevented from tipping over. For example, when fixing a single large panel, fixtures are installed at at least two separate locations on the side gate, and either one of the left or right ends of the large panel is fixed to the straddling piece of each fixture with at least two vertically arranged bolts. The large panel is fixed to the two fixtures with a total of at least four bolts, thereby maintaining a stable upright position of the large panel.

[0021] In another aspect of the transport vehicle according to the present invention, The fixing jig further includes a luggage receiving piece that bends from the other end of the overpass piece and extends horizontally to the outside of the gate, and the lower end of the luggage is placed on the luggage receiving piece.

[0022] According to this aspect, the fixing jig further includes a luggage receiving piece that bends from the other end of the overpass piece and extends horizontally to the outside of the gate, on which the lower end of the luggage is placed, thereby making it possible to hold luggage in an upright position even more stably.

[0023] In another aspect of the transport vehicle according to the present invention, The straddling piece is characterized in that it straddles the gate without contacting at least the upper end of the gate.

[0024] According to this aspect, since the crossing piece crosses the gate without contacting at least the upper end of the gate, the load of the load is not borne by the crossing piece of the fixture that holds the load onto the gate, and therefore deformation or damage due to the load being borne by the gate, which was not originally designed to bear the load, can be prevented. Here, "without contacting at least the upper end of the gate" includes both a form in which the crossing piece does not contact the upper end of the gate but contacts the inner and outer side surfaces of the gate, and a form in which the crossing piece does not contact the upper end of the gate or the inner and outer side surfaces of the gate (no contact with the gate at all). [Effects of the Invention]

[0025] As can be understood from the above explanation, the transport vehicle of the present invention can transport cargo, including as wide a range of large panels as possible, to a construction site while complying with legal height and width restrictions without giving third parties an intimidating or dangerous impression. [Brief explanation of the drawings]

[Figure 2] 2 is a view taken in the direction of an arrow II in FIG. 1, and is a side view of an example of a transport vehicle according to the embodiment. [Figure 3] FIG. 10 is a perspective view of an example of a protruding rod-shaped body. [Figure 4] 10(a) and 10(b) are plan views of other examples of protruding rod-shaped bodies. [Figure 5] FIG. 10 is a diagram showing a state in which the fixing jig is disposed on the gate. DETAILED DESCRIPTION OF THE INVENTION

[0027] Hereinafter, an example of a transport vehicle according to an embodiment will be described with reference to the accompanying drawings. In this specification and the drawings, substantially identical components are designated by the same reference numerals, and redundant description may be omitted.

[0028] [Transport vehicle according to the embodiment] An example of a transport vehicle according to an embodiment will be described with reference to Figures 1 to 5. Here, Figure 1 is a plan view of an example of a transport vehicle according to an embodiment, showing a state in which a large panel is fixed in an upright position on the outside of a gate. Also, Figure 2 is a view taken in the direction of arrow II in Figure 1, showing a side view of an example of a transport vehicle according to an embodiment, and Figure 3 is a perspective view of an example of a protruding rod-shaped body.

[0029] The transport vehicle 100 has a cabin 10 and a loading platform 20, and the loading platform 20 is equipped with side gates 30 (an example of a gate) and a rear gate 35 that can rotate freely.When loading normal cargo, the side gates 30 and the rear gate 35 are erected to form a loading space, and the cargo is loaded onto the loading platform 20 and transported.

[0030] In addition to the normal cargo loading configuration (general loading configuration) described above, the transport vehicle 100 is also capable of transporting cargo P by fixing it to the loading platform 20 in an upright position outside the side gate 30 (special loading configuration), as shown in the example shown.

[0031] The special loading configuration is a loading configuration when the cargo to be loaded is a wide range of large panels P, as shown in the example. Here, the large panels P include various panels such as roof panels, wall panels, and floor panels, as well as large window glass.

[0032] 2, the width Bp of the large panel P is, for example, more than 3 m, and the height Hp is longer than the width Bp. Therefore, if the large panel P is loaded in a lying position on the loading platform 20, it will exceed the legal width limit of 2.5 m for vehicles on public roads (including the width of the cargo if the vehicle is loaded with cargo), and therefore cannot be transported in a lying position.

[0033] Therefore, when large panel P is mounted upright on loading platform 20, the height from the ground to loading platform 20 is about 1 m. Therefore, if it is mounted with its height Hp in the vertical direction, it will exceed the legal height limit of 3.8 m for vehicles on public roads. Therefore, it must be mounted with its width Bp in the vertical direction. However, this also exceeds the height limit, making it impossible to transport.

[0034] Therefore, the transport vehicle 100 installs multiple fixing jigs 40 on the side gates 30 of the loading platform 20, and fixes the large panel P in an upright position with its width Bp in the vertical direction to each fixing jig 40 in a lowered state outside the side gates 30 at a position below the loading platform level (a position below h1 in Figure 2), thereby making it possible to transport the large panel P. Here, the height Hp of the large panel P is equal to or less than the length L1 of the loading platform 20.

[0035] Normally, luggage is loaded and transported so that it does not protrude from the loading platform 20, but since the luggage P is transported in a fixed state in an upright position outside the loading platform 20, the luggage P protrudes outside the vehicle body, eliminating the risk of giving an intimidating or dangerous impression to a third party who sees this transport vehicle.

[0036] Therefore, as shown in Figures 1 and 2, a protruding rod-shaped body 60 that widens the width of the cabin 10 is attached to the rear of the side of the cabin 10, and the large panel P is accommodated within the step area 25 of the cabin 10 (attached to the protruding rod-shaped body 60) and the cargo bed 20 in the plan view shown in Figure 1 and fixed to the cargo bed 20.

[0037] The protruding rod-shaped body 60 can be formed from resins such as hard urethane, synthetic resins, FRP (Fiber Reinforced Plastics), and various metals such as steel and aluminum, and as long as it has the rigidity (thickness) to withstand wind pressure and the like while driving, it is a lightweight component overall and does not impose a weight load on the vehicle body.

[0038] In the illustrated example, protruding rod-like bodies 60 are attached to the left and right sides of the cabin 10, and a large panel P is fixed in an upright position outside the left and right side gates 30 of the loading platform 20 for transportation. In this configuration, the width B1 obtained by adding the width of the cabin 10 to the width of the left and right protruding rod-like bodies 60 is greater than the width B2 of the loading platform 20, and therefore the width of the transport vehicle 100 is B1, and therefore the width of the protruding rod-like bodies 60 is set so that this width B1 is equal to or less than the legal width limit.

[0039] Here, if the protruding rod-shaped body is attached to only one of the left and right sides of the cabin 10 (if the large panel P is fixed only to the outside of one side gate 30), dimensions up to twice the width of the protruding rod-shaped body 60 in the illustrated example are allowed.

[0040] As shown in Figure 3, the protruding rod-shaped body 60 has fixed pieces 61, 63 that are fixed to the cabin 10, and a protruding piece 62 that extends from the fixed piece 61 at the front in the direction of travel to the side of the cabin 10 and has its tip curved toward the rear loading platform 20.

[0041] Each fixing piece 61, 63 has a bolt hole 61a, 63a, and as shown in Figures 1 and 2, a bolt 70 is inserted into each bolt hole 61a, 63a so as to be fixed to a bolt hole (not shown) in the cabin 10.

[0042] The protruding pieces 62 gradually widen out to the sides of the cabin 10 and curve gently towards the loading platform 20 side, so that the air resistance of the protruding rod-like bodies 60 is suppressed when the transport vehicle 100 travels.

[0043] 4(a) and (b) are plan views showing other examples of protruding rod-shaped bodies. The protruding rod-shaped body 60A shown in Fig. 4(a) has a gently curved protruding piece 62A with the same curvature, both ends of which are bent to provide two fixing pieces 61A and 63A.

[0044] On the other hand, the protruding rod-shaped body 60B shown in FIG. 4(b) has a protruding piece 62B that spreads out while bending laterally, and both ends of the protruding piece 62B are bent to provide two fixing pieces 61B and 63B.

[0045] Like the protruding rod-shaped body 60 shown in FIG. 3, both the protruding rod-shaped bodies 60A and 60B suppress the air resistance of the protruding rod-shaped bodies 60A and 60B when the transfer vehicle 100 travels.

[0046] By attaching the protruding rod-like bodies 60, 60A, 60B to the sides of the cabin 10 to widen the width, the width of a part of the cabin 10 can be easily widened without changing the structure of the cabin 10, and the protruding rod-like bodies 60, 60A, 60B can eliminate the sideward protrusion of the large panel P behind it.

[0047] Referring to Figure 1 makes it easy to understand, but since the large panel P does not protrude to the side from the protruding rod-shaped body 60 on the side of the cabin 10 when viewed in a plane, it is possible to prevent or suppress the impression of intimidation or danger that is given to third parties who see the transport vehicle 100 transporting the large panel P fixed to the outside of the loading platform 20.

[0048] Next, a fixing jig 40 for fixing the large panel P in an upright position on the outside of the loading platform 20 will be described with reference to Fig. 5. Fig. 5 shows the fixing jig disposed on the gate.

[0049] The fixing jig 40 has a U-shaped crossover piece 41 that spans the top of the gate 30, a load-bearing piece 42 that bends from one end of the crossover piece 41 and extends to the loading platform 20 and on which the counterweight 50 is loaded, and a luggage receiving piece 43 that bends from the other end of the crossover piece 41 and extends horizontally outside the gate 30.

[0050] The lower end of the large panel P is placed on the luggage receiving piece 43, and the multiple first bolt holes 41a of the overpass piece 41 and the second bolt holes (not shown) of the large panel P are connected to each other to form multiple communicating holes (not shown), and bolts 70 are screwed into each communicating hole, thereby fixing the large panel P to the fixing jig 40.

[0051] Furthermore, the crossing piece 41 straddles the gate 30 without coming into contact with the upper end or side of the gate 30, and is loaded in the X1 direction by fitting the recess 51 on the underside of the counterweight 50 into the load-bearing piece 42 extending above the loading platform 20.

[0052] In this way, by fixing the load-bearing piece 42 of the fixing jig 40 installed on the loading platform 20 with a counterweight 50 on the loading platform 20, and bolting the large panel P to multiple locations on the crossing piece 41 of the fixing jig 40 that straddles the tailgate 30, the large panel P can be fixed in an upright position simply by installing the fixing jig 40 with a simple configuration, without providing any special fixing means on the loading platform 20 of the transport vehicle 100.

[0053] Furthermore, since the large panel P is fixed to the overhead piece 41 by multiple vertical bolts 70, the stability of the upright position of the large panel P is ensured and the large panel P is prevented from falling over. In the illustrated example, as shown in Figure 2, fixing jigs 40 are installed at three separate locations on the gate 30, and the large panel P is fixed to the overhead piece 41 of each fixing jig 40 by two vertically arranged bolts 70, thereby maintaining a stable position of the upright large panel P.

[0054] Furthermore, because the overpass piece 41 straddles the gate 30 without contacting the upper end or side of the gate 30, the weight of the large panel P is not borne by the overpass piece 41 of the fixing jig 40 that holds the large panel P onto the gate 30. This prevents deformation or damage to the gate 30, which was not originally designed to bear the weight of the large panel P, due to bearing the weight of the large panel P.

[0055] The transport vehicle 100 makes it possible to transport as large a panel P as possible to a construction site while complying with legal height and width restrictions without giving third parties an intimidating or dangerous impression.

[0056] By transporting as many large panels P as possible to the construction site in this manner, the efficiency of the work of assembling the large panels P together at the construction site can be improved.

[0057] It should be noted that the present invention is not limited to the configurations shown here, and other embodiments may be possible in which other components are combined with the configurations described in the above embodiments. In this regard, the present invention can be modified within the scope of the present invention, and can be appropriately determined depending on the application form. [Explanation of symbols]
