This state represents a state in which the loading and unloading device 1 is stored below the rear of the cargo box B in the vehicle V, that is, a state in which the vehicle V can travel. On the other hand, in FIG. 2, after the whole of the receiving and lifting apparatus 1 is slid from the slide front end position (front position) of FIG. 1 to the rear of the cargo box B to reach a predetermined slide rear end position (rear position) It is a side view which shows the use condition which carries out the loading-and-unloading operation | work of a luggage | load by unfolding and raising / lowering the loading dock 19.

  A loading box B is mounted on the vehicle body 2 of the vehicle V. The vehicle body 2 of the present embodiment has a chassis frame 2a and a sub-frame 2b disposed so as to overlap on the chassis frame 2a. The sub frame 2 b is disposed on the lower surface of the cargo box B and has a function of reinforcing the cargo box B. Below the rear end of the chassis frame 2a, a so-called underfloor storage type receiving and lifting apparatus 1 is stored.

In FIG. 2, the fixed side support members 3 provided on the left and right in the vehicle width direction of the loading and unloading apparatus 1 respectively mount the slide rails 4 horizontally extending in the vehicle longitudinal direction and the vehicle body 2. A plurality of (three in this example) mounting brackets 5 and a connecting member 6 consisting of a square pipe connecting the front end portions of the pair of left and right slide rails 4 are provided.
The slide rail 4 and each mounting bracket 5 are fastened by two bolts 7 and a nut (not shown) (see FIG. 1). A support plate 8 is slidably mounted on the slide rail 4 in the longitudinal direction of the vehicle.

  A pair of left and right support plates 8 penetrates a cross member 9 consisting of a square pipe extending horizontally in the vehicle width direction (note that although both side end portions have three square pipes stacked for reinforcement, in the vehicle width direction Only one is erected), they are welded together integrally. Support brackets 10 and 11 are welded integrally with the cross member 9 on the outer side in the vehicle width direction than the support plate 8. A pair of left and right support brackets 10 and 11 is also provided.

  Lower portions of the pair of left and right support plates 8 are connected by a connecting member 12 made of a channel material (see FIG. 3). The support plate 8, the cross member 9, the support brackets 10 and 11, and the connection member 12 constitute a movable support member 13 which can slide in the longitudinal direction of the vehicle with respect to the fixed support member 3.

  An auxiliary link 14 is rotatably attached to the support bracket 10 within a predetermined range, and an upper arm 15 and a lift cylinder (lifting and lowering drive device) 16 are rotatably attached to the auxiliary link 14. The tip of the lift cylinder 16 is connected to a predetermined position of the upper arm 15 and applies a torque to the upper arm 15 by telescopic operation. A lower arm 17 is rotatably attached to the support bracket 11. The lift cylinder 16 is, for example, a single-acting hydraulic cylinder.

  The upper arm 15 and the lower arm 17 constitute a parallel link in which a quadrangle connecting the fulcrum and the point of action thereof is a parallelogram, and the distal end side thereof is moved up and down by the extension operation of the lift cylinder 16. The auxiliary link 14, the upper arm 15, the lift cylinder 16, and the lower arm 17 are provided as a pair on the left and right, and constitute an arm-type lifting device 18 that raises and lowers the load receiving table 19.

The cargo support 19 includes a main plate (base support) 191 horizontally attached to the tip of the upper arm 15 and the lower arm 17 and a sub-plate (foremost support) connected foldably and deployable thereto. A connecting portion 193 connecting the main plate 191 and the sub plate 192 is provided.
The connecting portion 193 has a hinge 193a having one end rotatably connected to the tip of the main plate 191 and the other end rotatably connected to the proximal end of the sub plate 192 (see also FIG. 1). ).

  With the above configuration, the sub plate 192 is folded on the main plate 191 during storage. Further, in use, the sub-plate 192 is developed, so that the receiving surface 19 a which is continuous from the upper surface of the main plate 191 to the upper surface of the sub-plate 192 is configured on the receiving table 19. On the receiving surface 19a, a load to be unloaded and unloaded from the shipping box B is placed.

  As described above, when the lift cylinder 16 is driven to extend and retract in the state where the receiving surface 19a is configured, the receiving position 19 is moved up to the elevation position where the floor surface b1 of the shipping box B and the receiving surface 19a become substantially the same height position It can be raised and lowered between the upper position in FIG. 2) and the grounded position (lower position in FIG. 2) grounded to the ground. As a result, by raising and lowering the cargo support 19 at the rear (right side in FIG. 2) of the loading box B, the load can be unloaded from the loading box B of the vehicle V.

  A roller mounting plate 20 is attached to each of the pair of left and right support plates 8 so as to project rearward, and a guide roller 21 is rotatably attached to the rear end thereof. The leading end of the sub plate 192 can be placed on the guide roller 21.

  Next, a slide cylinder (longitudinal drive device) 22 for sliding the loading and unloading device 1 between the front position and the rear position will be described. FIG. 3 is a plan view showing the slide cylinder 22 in its fully contracted state. FIG. 4A is a schematic side view showing the slide cylinder 22 in a fully contracted state, and FIG. 4B is a schematic side view showing the slide cylinder 22 in a most extended state.

  In FIG. 3, the slide cylinder 22 is configured by a pair of left and right cylinders 23 disposed between the left and right slide rails 4 in the vehicle width direction. The cylinder 23 is, for example, a double acting hydraulic cylinder. The cylinder bodies 24 of the left and right cylinders 23 are superimposed on each other in the state in which the front and rear end portions thereof are disposed reverse to each other, and are integrally connected by a pair of front and rear joint portions 25.

  In FIGS. 3 and 4, the cylinder 23 on the right side (the upper side in FIG. 3) has a boss 26a integrally formed on the tip of a piston rod 26 attached to a mounting plate 27 by a pin 28. The mounting plate 27 is fixed to a substantially middle portion of the connecting member 6 in the vehicle width direction. The cylinder 23 on the left side (the lower side in FIG. 3) is attached by a pin 31 to a mounting plate 30 in which a boss 26a of a piston rod 26 is fixed to a mount 29 extending in the vehicle longitudinal direction.

  The mounting base 29 is formed with an upper mounting base 29a on the upper surface of which the mounting plate 30 is fixed, a shorter length in the vehicle longitudinal direction than the upper mounting base 29a, and a bolt 32 at the lower part of the upper mounting base 29a. The lower mount 29b is fixed by a nut (not shown). A lower end of the lower mount 29 b is fixed to a substantially middle portion in the vehicle width direction of the connecting member 12. Further, the front end portion of the lower mount 29 b is fixed to a substantially middle portion in the vehicle width direction of the cross member 9.

  According to the above configuration, when using the pod 19 stored in the state shown in FIG. 1, the slide cylinder 22 is slid rearward by the extension operation to be retracted to the rearward position. Next, when the lift cylinder 16 is contracted, the upper arm 15 and the lower arm 17 rotate downward as shown by the solid line in FIG. 2, and the main plate 191 lands. At this time, the main plate 191 is horizontal, while the tip of the sub plate 192 is on the guide roller 21.

  Next, the sub plate 192 is raised by hand to lay the main plate 191 horizontally. Thus, the receiving board 19 is horizontally expanded. In this state, when the lift cylinder 16 is operated to extend, it is possible to lift the pod 19 to the raised position of FIG. 2 while keeping the pod 19 horizontal. In addition, if the lift cylinder 16 is contracted from the raised position, the load receiving table 19 can be lowered to the original position.

  If the lift cylinder 16 is further contracted after the lower arm 17 lands, the load receiver 19 tilts to lower its front end (rear end) by the action of the auxiliary link 14 and follows the ground. Thus, for example, the cart can be easily loaded and unloaded onto the receiving surface 19 a by moving a cart (load) having a caster (not shown) forward from the rear of the receiving table 19.

  In order to store the cargo support 19, the lower plate 17 lands, and the sub-plate 192 is erected from the state where the cargo support 19 is horizontal, and is further raised against the guide roller 21. Next, the upper arm 15 and the lower arm 17 are raised, and the sub plate 192 is folded on the main plate 191 by its own weight. Then, the slide cylinder 22 is contracted to draw the movable support member 13, the lifting device 18 and the cargo support 19 to the front position, and the storage state of FIG. 1 is obtained.

[Side stopper]
FIG. 5 is a side view showing the receiving stand 19 in an expanded state. In FIG. 5, side stoppers 33 are provided at both end portions in the left-right direction of the load receiving stand 19 for preventing the load on the load receiving surface 19 a of the load receiving stand 19 from falling outside in the left-right direction. In FIG. 5, only the side stoppers 33 provided at one end in the left-right direction of the receiving table 19 are shown.
The side stopper 33 has a first stopper member 34 extending in the front-rear direction of the main plate 191 and a second stopper member 35 extending in the front-rear direction of the sub plate 192.

FIG. 6 is an explanatory view of the loading platform in the unfolded state, and the lower view is an explanatory view showing a cross section of the main plate 191 as viewed from the front and back direction. The upper view is a cross section of the sub plate 192 as viewed from the front and back direction. It is an explanatory view shown.
As shown in the lower part of FIG. 6, the first stopper member 34 has an attachment portion 34 a having a U-shaped cross section, which is fixed to the lateral side of the main plate 191. The mounting portion 34 a covers the left and right edges of the main plate 191 from the top, bottom, and outside, and has a function of protecting the edges of the main plate 191.

  Further, in the unfolded state, the first stopper member 34 extends from the upper end of the outer surface 34a1 of the mounting portion 34a outward and upward, and extends from the tip of the support portion 34b directly above the load receiving surface 19a. And an upwardly projecting side wall 34c.

  As shown in the upper view of FIG. 6, the second stopper member 35 has a mounting portion 35 a having a U-shaped cross section fixed to the lateral side of the sub plate 192. The mounting portion 35 a covers the left and right edges of the sub plate 192 from the upper, lower, and outer sides, and has a function of protecting the edge of the sub plate 192.

  Further, in the unfolded state, the second stopper member 35 extends from the lower end of the outer surface 35a1 of the mounting portion 35a outward and upward, and the tip of the second stopper member 35b extends directly upward from the tip of the support 35b. And a side wall portion 35c which protrudes upward beyond 19a. Thus, a recessed groove 35d is formed by the outer side surface 35a1 of the mounting portion 35a, the support portion 35b, and the side wall portion 35c, and a recessed portion 35e is formed in the outer side surface 35b1 of the support portion 35b.

Then, as shown in FIG. 1, when the cargo support 19 is in a folded state, as shown in FIG. 7, the sub plate 192 is covered on the main plate 191. The side wall 34c on the lower main plate 191 side protrudes upward, but the side wall 35c on the sub plate 192 protrudes downward more outward than the side wall 34c.
As a result, most of the side wall portion 34c on the main plate 191 side is accommodated in the concave groove 35d on the sub plate 192 side, so the main plate 191 and the sub plate 192 can be brought close to each other in the vertical direction and folded. It becomes possible to thin the receiving board 19 in the vertical direction.

[Side light emitter]
As shown in FIG. 5 and FIG. 6, a plurality of side light emitters 41 are provided at both ends in the left-right direction of the receiving table 19. In FIG. 5, only the side light emitters 41 provided at one end in the left-right direction of the receiving table 19 are shown. The side light emitters 41 of this embodiment include a plurality of first side light emitters 42 attached to the side stoppers 33 (first stopper members 34) on the main plate 191 side, and the side stoppers 33 on the sub plate 192 ( And a plurality of second side light emitters 43 attached to the second stopper member 35).

  A fixing portion 44 extending in the front-rear direction is fixed to the outer side surface 34a1 of the mounting portion 34a of the first stopper member 34. A plurality of first side light emitters 42 are attached to the fixing portion 44 at predetermined intervals in the longitudinal direction so as to emit light toward the outside of the load receiving table 19. The first side light emitter 42 is, for example, an LED lamp. In addition, although the 1st side light-emitting body 42 is attached at fixed intervals in the longitudinal direction of the fixing part 44, it may be attached at unequal intervals.

  A fixing portion 45 extending in the front-rear direction is fixed to the recess 35 e (the outer side surface 35 b 1 of the support portion 35 b) of the second stopper member 35. A plurality of second side light emitters 43 are attached to the fixing portion 45 at predetermined intervals in the longitudinal direction so as to emit light toward the outside of the receiving table 19. The second side light emitter 43 is, for example, an LED lamp as in the case of the first side light emitter 42. The second side luminous body 43 is fixed to the recess 35e of the second stopper member 35 and is located on the inner side in the left-right direction of the load receiving stand 19 than the side wall 35c, so the obstacle on the side of the load receiving stand 19 is on the second side. There is little risk of direct contact with the direction light emitter 43, and damage to the second side light emitter 43 can be prevented. And since the 2nd side light-emitting body 43 has turned to the side and downward in the unfolded state of the receiving platform 19 shown in FIG. 6, it can illuminate the ground around the side of the receiving platform 19. On the other hand, since the second side light emitter 43 faces sideward and upward in the folded state of the receiving table 19 shown in FIG. 7, attention is paid to the operator and the surrounding pedestrian when sliding the receiving table 19. It can prompt you. Although the second side light emitters 43 are attached at regular intervals in the longitudinal direction of the fixing portion 45, they may be attached at irregular intervals.

  The first and second side light emitters 42 and 43 may be turned on and off in conjunction with a main switch (not shown) of the receiving and lifting apparatus 1 provided in the driver's cabin of the vehicle V, or a dedicated switch You may make it light and light-extinguish by operating (illustration omitted). In addition, the first and second side light emitters 42 and 43 have a timing at which a sensor or the like (not shown) detects the operation state of the load receiving table 19 (for example, a sensor for detecting that the load receiving table 19 is at a forward position) It is also possible to automatically turn on and off when it is detected that the vehicle has left, that is, when the pod 19 is slightly slid from the front position. In this case, since the platform 19 automatically turns on when the platform 19 slides backward and slightly protrudes backward from the front position, the platform 19 can be easily viewed during the sliding operation.

  With the above configuration, as shown in FIG. 7, in a state where the sub plate 192 is covered on the main plate 191, the first side light emitter 42 is disposed on the outermost side of the receiving board 19, and The two-side light emitter 43 is disposed below the tip 35c1 of the side wall 35c on the sub plate 192 side. Therefore, even when the sub plate 192 is folded on the main plate 191 (see FIG. 1), the first and second side light emitters 42 and 43 emit light toward the outside of the receiving table. Can.

[Rear stopper]
Next, the rear stopper 36 provided at the tip of the sub plate 192 of the receiving table 19 will be described.
FIG. 8 is a side view showing the tip of the sub plate 192. As shown in FIG. FIG. 9 is a plan view showing a part of the tip portion of the sub plate 192. As shown in FIG. FIG. 9 is a plan view when the rear stopper 36 is at a retracted position (two-dot chain line) described later.
In FIG. 8 and FIG. 9, the rear stopper 36 is provided at the front end portion of the sub plate 192 so as to be selectively undulating relative to the receiving surface 19 a.

  The rear stopper 36 is a long member extending in the left and right direction (vertical direction in FIG. 9), and its base end portion is rotatably attached with a pivot portion 194 formed in the sub plate 192 extending in the left and right direction as a fulcrum. ing. Further, the rear stopper 36 has a flat plate portion 36 a having one end portion attached to the pivot portion 194 and a bulging portion 36 b formed at the other end portion of the flat plate portion 36 a.

  A storage space K for storing the rear stopper 36 on the sub plate 192 so that the mounting surface 36a1, which is the outer surface of the flat plate portion 36a, becomes substantially flush with the load receiving surface 19a of the load receiving table 19 when the rear stopper 36 rotates. Is formed. Further, on the sub plate 192, in the state where the rear stopper 36 is stored in the storage space K, an abutting surface 195 with which the lower surface of the bulging portion 36b of the rear stopper 36 abuts is formed.

  The rear stopper 36 projects from the load receiving surface 19 a of the load receiving table 19 by pivoting as described above to limit the rearward movement of the load on the load receiving surface 19 a (solid line); It is possible to selectively move up and down between a retracted position (two-dot chain line) which is retracted into the storage space K to allow backward movement of the load on the receiving surface 19a. A lock mechanism 37 for holding the rear stopper 36 at the retracted position is disposed at one end in the left-right direction of the storage space K of the sub plate 192.

[Backlight]
At the left and right end portions of the flat plate portion 36a of the rear stopper 36, elongated holes 36c penetrating in the thickness direction are formed to extend in the left-right direction. On the back surface of the flat plate portion 36a, a pair of fixing portions 52 extending in the left-right direction so as to close the long holes 36c is fixed. The fixing portion 52 is formed in a size to be accommodated in the storage space K when the rear stopper 36 is in the retracted position. Further, the fixing portion 52 is disposed on the center side in the left-right direction with respect to the lock mechanism 37 so as not to interfere with the lock mechanism 37 in a state of being accommodated in the storage space K.

  A plurality of rear light emitters 51 are attached at predetermined intervals in the longitudinal direction to a portion corresponding to the long hole 36 c in the inside of each fixing portion 52. The rear light emitter 51 is, for example, an LED lamp as in the case of the side light emitter 41 described above. As a result, when the rear stopper 36 is in the projecting position, the rear light emitter 51 emits light toward the rear of the cargo support 19 through the long hole 36 c. In the state of K, the light emission area of the rear light emitter 51 when viewed from the rear of the cargo support 19 is larger than when the rear stopper 36 is at the retracted position, so the amount of light emission to the rear of the rear light emitter 51 It can be increased.

  In addition, when the rear stopper 36 is in the retracted position, the rear light emitter 51 is housed in the storage space K together with the fixed portion 52. As a result, the amount of projection of the rear light emitter 51 with respect to the receiving surface 19 a of the receiving table 19 can be suppressed, so that the movement of the load by the rear light emitter 51 can be suppressed. Further, as shown in FIG. 9, since the rear light emitter 51 is housed at the center side in the left-right direction with respect to the lock mechanism 37, it does not interfere with the lock mechanism 37.

Although the rear light emitter 51 of the present embodiment is attached to the back surface side of the flat plate portion 36a of the rear stopper 36, as shown in FIG. 10, it is fixed to the surface (mounting surface 36a1) of the flat plate portion 36a. You may make it attach to the fixing | fixed part 52. FIG. In this case, since the fixing portion 52 does not interfere with the lock mechanism 37, as shown in FIG. 11, the fixing portion 52 can be disposed close to one end side in the left-right direction of the flat plate portion 36a together with the rear light emitter 51.
However, from the viewpoint of suppressing the amount of protrusion of the rear light emitter 51 with respect to the mounting surface 36a1 when the rear stopper 36 is in the retracted position, it is preferable to attach it to the back surface side of the flat plate portion 36a as in this embodiment.

[Function effect]

One end of a link 64 is rotatably attached to the other end (upper end in FIG. 13) of the reflecting plate stay 61 via a second hinge 63. The link 64 is disposed above the connecting shaft 193 b of the hinge 193 a in the folded state of the pod 19. The other end of the link 64 is rotatably attached to the back surface of the proximal end of the sub plate 192 via a third hinge 65.
The reflecting plate stay 61, the first hinge 62, the second hinge 63, the link 64, and the third hinge 65 constitute a reflecting plate support mechanism 60.

  As shown in FIG. 13, the electrical wiring 49 is a base of the first hinge 62, the reflector stay 61, the second hinge 63, the link 64, the third hinge 65, and the sub plate 192 from the rear end of the main plate 191. It is wired along the order of the back of the end. The electrical wiring 49 is, as shown in FIG. 12, wired along the axis P of the third hinge 65 on the back surface of the sub plate 192 and connected to the light source 46. In addition, the point which abbreviate | omitted description in 2nd Embodiment is the same as that of 1st Embodiment.

  FIG. 14 is a side sectional view showing the movement of the reflecting plate support mechanism 60 when the receiving pad 19 is unfolded from the folded state, where (a) is in the folded state, (b) is in the unfolded state, (c) is It is in an expanded state. When (a) and (c) of FIG. 14 are compared, when the loading tray 19 is unfolded from the folded state, the rotation angles of the first hinge 62, the second hinge 63 and the third hinge 65 are each 180 °. It is understood that it is less than. For this reason, the electrical wiring 49 is wired along the first to third hinges 62, 63, 65, which have a rotation angle of less than 180 °, when the load receiving base 19 is expanded from the folded state.

On the other hand, when, for example, the electrical wiring 49 is wired directly from the rear end of the main plate 191 to the base end of the sub plate 192 without the connecting portion 193, the electrical wiring 49 together with the sub plate 192 It will rotate 180 degrees with respect to the main plate 191.
Therefore, according to the receiving and lifting apparatus 1 of the second embodiment, compared to the case where the electrical wiring 49 is directly wired from the main plate 191 to the sub plate 192 without passing through the connecting portion 193, It is possible to reduce the degree of bending of the electrical wiring 49 when the plate 192 is folded and unfolded. Thus, disconnection of the electrical wiring 49 can be effectively suppressed.

It should be understood that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is indicated not by the meaning described above but by the claims, and is intended to include the meanings equivalent to the claims and all modifications within the scope.
For example, although the side light emitter 41 is attached to the side stopper 33, it may be attached directly to the main plate 191 or the sub plate 192. The rear light emitter 51 is attached to the rear stopper 36, but may be attached directly to the sub plate 192.

Further, in the second embodiment, the electrical wiring 49 is wired along the reflection plate support mechanism 60, but is wired from the rear end of the main plate 191 to the base end of the sub plate 192 via the hinge 193a. It is also good.
Further, the wiring of the electric wiring 49 in the second embodiment is not limited to the electric wiring (not shown) connected to the second side light emitter 43 on the sub plate 192 side in the receiving and lifting apparatus 1 of the first embodiment. It can apply.

  Further, although the receiving and lifting apparatus 1 according to the present invention has been described as being applied to an under-floor storage type receiving and lifting apparatus, the present invention may be applied to other types of receiving and lifting apparatus such as upright storage and vertical lifting. Can.
