Abstract
Description
Technical Field
[0001] The present invention relates to an attachment structure of a light-emitting body disposed on a wing vehicle.
Background Art
[0002] The loading platform of a truck, which is a vehicle for cargo transportation, has an open-topped lidless loading platform or a box-shaped loading platform with a ceiling and a sealed perimeter. In recent years, box-shaped loading platforms that can prevent damage to cargo caused by wind and rain, simplify the packaging of cargo, and are also easy to prevent cargo from falling off have become widely popular. For the purpose of rationalizing cargo handling operations such as rapid loading and unloading of cargo, many wing vehicles equipped with a flip-up wing roof are also adopted.
[0003] In the loading platform of the wing vehicle, a roof portion divided into left and right along a center line (center beam) extending in the front-rear direction on the ceiling and a side wall portion constituting the side body of the loading platform are integrated to form a wing roof having a substantially L-shaped cross section. The left and right wing roofs are opened and closed in a flip-up manner by an actuator such as a hydraulic cylinder around a hinge attached to the center beam. A flap that opens downward is disposed at the lower part of the side surface of the loading platform of the wing vehicle. When performing a cargo handling operation, the wing roof is opened upward and the flap is opened downward to open the side of the loading platform over the entire surface.
[0004] A lighting fixture for illuminating the cargo compartment is disposed on the loading platform of the wing vehicle. Generally, the lighting fixture is disposed substantially at the center in the width direction of the roof portion of the wing roof. However, for example, it may be disposed on the center beam that supports the wing roof so that the cargo compartment is illuminated both when the wing roof is closed and when it is open (see, for example, Patent Document 1).
[0005] Furthermore, it has been proposed to install the lighting fixture not on the center beam as described above, but on the inside of the upper corner connecting the roof and side walls of the wing roof, so that when the wing roof is opened, the lighting is directed outwards towards the surrounding area of the cargo bed, improving work efficiency when loading and unloading cargo around the cargo bed at night (see, for example, Patent Document 2).

[0006] [Patent Document 1] Japanese Utility Model Publication No. 07-037861 [Patent Document 2] Utility Model Registration No. 3197718 Gazette [Overview of the project] [Problems that the invention aims to solve]
[0007] Incidentally, when performing cargo handling operations on a wing-type truck, the wing roof and side panels are often opened to fully open the sides of the cargo bed, and a forklift is operated to load and unload cargo on pallets from the sides of the cargo bed. However, if lighting fixtures are installed on the center beam supporting the wing roof or on the inside of the upper corners connecting the roof and side walls of the wing roof, as in the conventional technology described above, the lighting fixtures will be located in front of the forklift operator performing the cargo handling operations, regardless of where they are installed. In particular, when using a forklift to unload pallets loaded with cargo from the cargo bed of a wing-type truck at night, the light from the aforementioned lighting fixtures shines on the cargo on the pallets, casting a shadow on the front side. As a result, visibility around the front of the pallet becomes difficult, hindering the operator's ability to operate the forklift and insert the forks into the pallet's insertion holes, resulting in poor work efficiency.
[0008] This invention has been made in view of the above facts, and its main technical problem is to provide a mounting structure for a light-emitting element that realizes a highly visible working environment when cargo handling operations are carried out with the wing roof of a wing vehicle open. [Means for solving the problem]
[0009] To solve the above-mentioned main technical problems, the present invention provides a mounting structure for a light-emitting element disposed inside the cargo compartment of a pair of left and right wing roofs that constitute a part of the cargo bed of a wing vehicle, wherein the wing roof comprises a roof portion that constitutes the ceiling and a side wall portion that constitutes the lateral surface, and the lower edge of the side wall portion is a rail lower side, or the rail lower side Located adjacent to the upper end The lower side of the rail Through a receiving recess along the longitudinal direction A light-emitting object is embedded. The light-emitting element is positioned outward and above the vehicle width edge of the floor surface constituting the cargo bed of the wing vehicle when the wing roof is opened, and the light emitted from the light-emitting element is directed from outward and above the vehicle width edge towards the cargo compartment, so as to radiate in the direction of the cargo compartment and outward from the vehicle width edge of the floor surface, and is embedded in the wing roof. A mounting structure for a light-emitting element is provided.
[0010] Applicable Preferably, a long divider is provided at the upper end of the lower side of the rail on the cargo compartment side, and a housing recess is formed along the longitudinal direction of the divider for housing the long light-emitting element.
[0011] Preferably, the inner end face of the divider is formed so as not to protrude further into the cargo compartment than the inner end face of the lining support member that supports the lining plate disposed on the cargo compartment side of the side wall. Furthermore, the light-emitting element is housed in the housing recess of the divider via a spacer having a substantially C-shaped cross-section and an opening that opens in the longitudinal direction. When the light-emitting element is disposed, the spacer is housed so that its opening aligns with the opening of the recess of the divider, and when the light-emitting element is not disposed, the spacer is housed so that it closes the opening of the housing recess of the divider. stomach. [Effects of the Invention]
[0012] The present invention relates to a mounting structure for a light-emitting element that is disposed on the inside of the cargo compartment of a pair of left and right wing roofs that constitute a part of the cargo bed of a wing vehicle, wherein the wing roof comprises a roof portion that constitutes the ceiling and a side wall portion that constitutes the lateral surface, and the lower edge of the side wall portion is the rail lower side, or the rail lower side Located adjacent to the upper end Along the longitudinal direction of the lower side of the rail Through the recessed area A light-emitting object is embedded. The light-emitting element is positioned outward and above the vehicle width edge of the floor surface constituting the cargo bed of the wing vehicle when the wing roof is opened, and the light emitted from the light-emitting element is directed from outward and above the vehicle width edge towards the cargo compartment, so as to radiate in the direction of the cargo compartment and outward from the vehicle width edge of the floor surface, and is embedded in the wing roof. As such, the light emitted from the light-emitting element is projected not only inwards towards the cargo compartment but also outwards from both ends of the floor surface. For example, this improves visibility when positioning the tips of forklift forks on a pallet loaded with cargo on the cargo bed, contributing to improved work efficiency. Furthermore, since the light-emitting element is embedded in the side wall that constitutes the wing roof, it does not compress the cargo compartment and reduce its volume, nor does it cause problems such as damaging the cargo.

[Figure 5] This is a perspective view from the rear-diagonal inside of the cargo compartment, showing the area near the lower rail side and the divider in which the light-emitting element is embedded. [Figure 6] Figure 1 is a conceptual diagram showing how cargo handling operations are performed in a wing vehicle. [Modes for carrying out the invention]
[0014] Hereinafter, embodiments of the mounting structure for a light-emitting element based on the present invention will be described in detail with reference to the attached drawings.
[0015] FIG. 1 shows a wing vehicle 1 having a mounting structure for a light emitter according to the present embodiment. The wing vehicle 1 includes a loading platform 3 mounted on the rear side of the vehicle body 2 with respect to the traveling direction (the left rear side in the figure), and a cabin 4 mounted on the front side of the loading platform 3 and constituting a living space for the driver. FIG. 1 is a perspective view of the wing vehicle 1 seen from the left rear obliquely with one (left side) of the wing roofs 5 of the loading platform 3 opened and the other (right side) of the wing roofs 5 closed. The loading platform 3 includes the above-described wing roofs 5, 5, a deflector 6, a front wall 7, a floor surface 8, and a rear opening 9.
[0016] The wing roofs 5 constitute both the left and right sides of the loading platform 3, and include a roof portion 5a and a side wall portion 5b that are connected to form a substantially L-shaped cross section. When the wing roofs 5 are closed, the roof portions 5a of the left and right wing roofs 5 constitute the ceiling of the loading platform 3, and the side wall portions 5b constitute the side surfaces of the loading platform 3. An inner lining plate 14 is disposed on the inner surface of the cargo compartment 20 of the side wall portion 5b, and lashing rails 15 for fixing lashing belts (not shown) disposed to prevent the cargo from tipping over or collapsing are disposed along the vehicle longitudinal direction. An aluminum rail lower side 16 extending in the longitudinal direction of the vehicle body 2 is disposed at the lower edge of the side wall portion 5b of the wing roof 5. In the present embodiment, a divider 17 is disposed inside the side wall portion 5b of the wing roof 5 and adjacent to the upper side of the rail lower side 16, and a long light emitter 30 described later is embedded in the divider 17. Note that the wing roof 5 in FIG. 1 is shown with some components omitted and simplified.
[0017] The wing roof 5 is supported by a center beam 51 that passes through the center of the ceiling and extends in the longitudinal direction of the wing vehicle 1, and is opened and closed by a cylinder 52 that is disposed at the front and rear ends of the wing roof 5 and operates by hydraulic pressure or the like with the center beam 51 as a rotation axis. Note that in FIG. 1, only the left wing roof 5 is shown in an opened state, but the right wing roof 5 is also opened and closed by the same configuration.
[0018] Tailgates 6 are provided at both ends of the floor surface 8 of the cargo bed 3 in the vehicle width direction, and these tailgates 6 rotate around these ends. By closing the wing roof 5 and the tailgates 6, the sides of the cargo bed 3 are closed. In the embodiment shown in the figure, the tailgates 6 are divided into two sections in the front-rear direction of the cargo bed 3, but the invention is not limited to this.
[0019] The rear opening 9 comprises a pair of rear posts 10, 10 that form both sides of the rear opening 9, and a rear upper 11 that connects the upper ends of the pair of rear posts 10, 10 in the left-right direction, forming a gate-shaped opening frame on the rear end of the floor surface 8. In addition, multiple hinges 12 are installed on the rear posts 10, 10 when viewed in the vertical direction, and the left and right rear doors 13 that open and close the opening frame of the rear opening 9 in a double-door motion are pivotally supported. By closing the wing roof 5, the tailgate 6, and the rear doors 13, the cargo area 20 formed on the floor surface 8 becomes a closed space.
[0020] Figure 2 shows a side view of the right wing roof 5 as seen from inside the cargo compartment 20 (parts are omitted for explanatory purposes). In Figure 2, the left side indicated by arrow F is the front side of the wing vehicle 1, and the right side indicated by arrow B is the rear side of the wing vehicle 1. Figure 3 shows a cross-sectional view of the position indicated by AA in Figure 2, Figure 4(a) shows a cross-sectional view of the position indicated by BB in Figure 2, and Figure 4(b) shows a cross-sectional view of the position indicated by CC in Figure 2. Figure 5 shows a perspective view of the rail lower side 16 and the vicinity of the divider 17 in which the light-emitting body 30 is embedded, seen from the diagonal rear inside the cargo compartment 20, showing the state in which the light-emitting body 30 is attached to the wing roof 5 based on the light-emitting body mounting structure of the present invention. For explanatory purposes, a part of the side wall 5b is omitted in Figure 3, and Figures 4 and 5 are shown with a changed magnification and enlarged views of key parts. Furthermore, Figure 5 shows a perspective view in which the rail lower side 16 and divider 17 are shown in cross-section at the position indicated by BB in Figure 2, and the spacer 18 housing the light-emitting element 30 is shown in cross-section at a position on the near side, different from the rail lower side 16 and divider 17, for the sake of explanation, and the light-emitting element 30 is shown in perspective view without a cross-section.
[0021] As can be understood by referring to Figure 3, an interior lining plate 14 is provided on the inner surface of the side wall 5b on the cargo compartment 20 side, and is divided into an upper interior lining plate 14 and a lower interior lining plate 14. A lashing rail 15 is provided between the upper interior lining plate 14 and the lower interior lining plate 14. An outer plate 5c with a corrugated cross-section is provided on the outside (right side in the figure) of the side wall 5b, and the interior of the side wall 5b is either hollow or has insulation material installed.
[0022] In this embodiment, as shown in enlarged view in Figures 4(a) and 5, a divider 17 is provided on the cargo compartment 20 side of the side wall portion 5b, adjacent to the upper end of the rail lower side 16, and having a housing recess 17a for housing a light-emitting element 30 along the rail lower side 16. An engaging recess 17b formed on the lower end of the divider 17 engages with an engaging projection 16a formed on the upper end of the rail lower side 16 on the cargo compartment 20 side, and an engaging projection 17c formed on the upper end of the divider 17 engages with an engaging recess 19a of the interior lining support member 19 that supports the interior lining plate 14. The rail lower side 16 is provided with sealing members 16b and 16c that seal the space between it and the tailgate 6 (omitted in this figure), which is closed first when the wing roof 5 is closed.
[0023] The receiving recess 17a of the divider 17 has an opening formed by a hanging portion 17d and an upright portion 17e formed along the longitudinal direction of the divider 17, and the light-emitting element 30 is housed in the receiving recess 17a via a spacer 18 having a substantially C-shaped cross-section.
[0024] In this embodiment, the light-emitting element 30 arranged on the wing roof 5 is elongated and comprises multiple LED light-emitting parts 32 that emit light when power is supplied by wiring 34, as shown in Figure 5. Although not shown, multiple light-emitting elements 30 in this embodiment are connected in series by wiring 34 at regular intervals. When housing the light-emitting elements 30 in the divider 17, the opening 18a of the spacer 18 is aligned with the aforementioned opening in the housing recess 17a of the divider 17 so that the light-emitting parts 32 of the light-emitting elements 30 are exposed to the cargo compartment 20 side from the opening of the divider 17. Furthermore, when housing multiple light-emitting elements 30 along the divider 17, in areas where only the wiring 34 connecting the light-emitting elements 30 at intervals is exposed from the opening of the divider 17, the opening 18a of the spacer 18 is positioned towards the inside of the housing recess 17a of the divider 17, as can be understood from Figures 4(b) and 5, thereby closing the opening of the housing recess 17a of the divider 17. This protects the wiring 34 within the recessed area 17a of the divider 17, prevents dust and debris from entering the recessed area 17a, and keeps the wiring 34 out of sight, thus maintaining an aesthetic appearance.
[0025] In the above explanation, we described the structure when the light-emitting element 30 is attached to the right-side wing roof 5. However, the same configuration, with the left side reversed, is used to arrange the light-emitting element 30 on the opposite side (left side) of the wing roof 5 (detailed explanation omitted).
[0026] Furthermore, in the wing vehicle 1 of this embodiment shown in Figure 1, limit switches 53 are installed near the center beam 51 that pivotally supports the roof portion 5a of the wing roof 5, at a position where the roof portion 5a is opened and closed. The limit switches 53 are installed corresponding to each of the left and right wing roofs 5 and are switches that operate when the wing roofs 5 are closed. Even if the light switch for the light-emitting element 30 is turned ON by the operator's hand, when the wing roof 5 is closed, the limit switches 53 are activated and the light-emitting element 30 turns off. In other words, in the wing vehicle 1 shown in Figure 1, when the operator turns on the light-emitting element 30, only the light-emitting element 30 installed on the left wing roof 5 lights up, and the light-emitting element 30 installed on the right wing roof 5 turns off. The installation of such a limit switch 53 eliminates the problem of reduced work efficiency in cargo handling operations, as light from the illuminated element 30 of the closed wing roof 5 enters the line of sight of workers performing cargo handling operations on the open side of the wing roof 5.
[0027] According to the above-described mounting structure for the light-emitting element, when the wing roof 5 of the wing vehicle 1 is opened and cargo handling work is performed at night or in a dark factory, a work environment with excellent visibility is realized. More specifically, as shown in Figure 6, when the wing roof 5 is opened, the light-emitting element 30 is positioned above both ends in the vehicle width direction of the floor surface 8 that constitutes the cargo bed 3 of the wing vehicle 1. As a result, the light G emitted from the light-emitting element 30 is projected not only inward into the cargo compartment 20 but also outward from both ends of the floor surface 8. This improves the visibility of the area where the tips of the forks 42 of the forklift 40 are positioned relative to the pallet 62 on which the cargo 60 is placed, contributing to improved work efficiency. In particular, if the light emitter 30 is positioned so that it is outside the side edge in the vehicle width direction of the cargo bed 3 of the wing vehicle 1 (the position shown by the dashed line P in Figure 6) when the wing roof 5 is opened, then light G will be irradiated from outside the side edge toward the inside of the cargo compartment 20, and the tip area of the forks 42 will be illuminated without the light G being obstructed by the cargo 60 inside the cargo compartment 20, providing a better working environment for the worker H operating the forklift 40. Note that in Figure 6, the rear door 13 of the cargo bed 3 is omitted for illustrative purposes.
[0028] Furthermore, in this embodiment, as shown in an enlarged view to the left of Figure 4(a), the end face of the divider 17 housing the light-emitting element 30 on the cargo compartment 20 side is embedded so as not to protrude further into the cargo compartment 20 than the inner end face (indicated by the dashed line L in the figure) of the lining plate support member 19 disposed on the cargo compartment 20 side of the side wall portion 5b. As a result, compared to the conventional configuration, even when the light-emitting element 30 is installed according to the present invention, the volume of the cargo compartment 20 is not compressed, and the light-emitting element does not come into contact with the cargo stored in the cargo compartment 20, thus preventing damage to the cargo.
[0029] In the embodiment described above, a divider 17 is provided above the rail lower side 16 that constitutes the wing roof 5, and a light-emitting element 30 is embedded in the receiving recess 17a of the divider 17 to attach the light-emitting element to the wing roof 5. However, the present invention is not limited thereto. For example, on the inside of the cargo compartment 20 of the side wall portion 5b, the rail lower side 16 and the interior lining support member 19 may be directly connected without providing a divider 17, and a receiving recess corresponding to the above-described receiving recess 17a may be formed in the rail lower side 16 to accommodate the light-emitting element 30. Alternatively, the receiving recess for accommodating the light-emitting element 30 may be formed in the interior lining support member 19 above the rail lower side 16, or in another member formed on the roof portion 5a side of the interior lining support member 19 to accommodate the light-emitting element 30. Furthermore, when multiple light-emitting elements 30 are arranged at intervals on each of the left and right wing roofs 5, the positions of the light-emitting elements 30 on the left and right wing roofs 5 may be arranged alternately in the front-to-back direction, i.e., in a staggered pattern. By arranging them in this way, the entire area around the wing vehicle can be efficiently illuminated by the light-emitting elements 30.
[0030] Furthermore, the structure for attaching the light-emitting element 30 to the wing roof 5 can also function effectively if configured as follows.
[0031] In other words, dividers similar to the long divider 17 described above can be arranged along the frame supporting the lateral surface of the wing roof 5, for example, the rail upper side 54, post side front 55, and post side rear 56 shown in Figure 1, and the light-emitting element 30 similar to the one described above can be housed and installed in the housing recess formed in the divider. This allows the light-emitting element 30 to be installed without compromising the volume inside the cargo compartment 20. In this case, it is preferable to house the light-emitting element 30 in the housing recess via a spacer similar to the spacer 18 described above. [Explanation of Symbols]
