  However, in the former conventional example, since the over fender which is an interference object is integrated with the side door, it is necessary to support the overhang fender overhanging with the side door in a cantilever manner. In addition to being required to be rigid, it is also necessary for the fixed hinge to the vehicle to have a strong structure.

  In the latter conventional example, in order to avoid the object of interference, a complicated hinge structure consisting of a large number of parts such as rails, rollers, cams, and guide rails is required. Increased and expensive.

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide an inexpensive lid opening and closing device suitable for avoiding interference objects on the opening and closing locus.

  The present invention is capable of rotating around a hinge shaft that is disposed horizontally in the vicinity of any edge of the opening, and is in a closed state in which the opening is rotated around the hinge axis and overlaps the opening. A lid opening / closing device that is operated to open and close to an open state, wherein at least one of both shaft ends of the hinge shaft is offset in a plane perpendicular to the edge, and the hinge shaft is moved relative to the edge. The hinge shaft is inclined with respect to the opening surface by being inclined and / or offset at least one of both shaft ends of the hinge shaft in a direction perpendicular to the opening surface of the opening portion closed by the lid. It is characterized by having arranged.

  Therefore, in the present invention, at least one of both axial ends of the hinge axis of the lid is offset in a plane perpendicular to the edge of the opening, and the hinge axis is inclined with respect to the edge, and / or Since at least one of both ends of the hinge shaft is offset in a direction perpendicular to the opening surface of the opening portion closed by the lid body and the hinge shaft is inclined with respect to the opening surface, the lid body is opened. The rotation trajectory can be tilted, and the cover plate can be rotated in the direction in which the edge of the cover plate moves away from the interference object such as an over fender. For example, the shape of the over fender that is the interference object is reduced. Thus, without changing the shape of the object to be interfered with, it is possible to exhibit sufficient functions such as making the object to be interfered with, such as an over fender having a sufficiently large size and a good appearance. On the other hand, the lid body does not need to be formed small in anticipation of interference with the interference object, so that the degree of freedom in design can be improved and the shape can be improved.

  Hereinafter, an embodiment of a lid opening and closing device of the present invention will be described with reference to FIGS. 1 is a side view of a forklift applied to a side box cover opening / closing device, FIG. 2 is an enlarged side view of the side box, FIG. 3 is a perspective view showing a lid opening / closing device of this embodiment, and FIG.

  FIG. 1 shows a forklift 1 to which a lid opening / closing device of the present embodiment is applied to a cover 5 (lid, hatch) of a side box 4 arranged on the side of a vehicle body 7 between front and rear wheels 2, 3. ing. The forklift 1 includes a front wheel 2 serving as a driving wheel and a rear wheel 3 serving as a steering wheel. A mast 6 serving as a cargo handling device is disposed in front of the vehicle body, and a counterweight 8 is disposed behind the vehicle body 7. Further, a driver's seat 10 is arranged on a top panel 9 constituting an engine room or a battery compartment, and an instrument panel, a cargo handling lever, a steering handle, etc. are arranged on a console 11 erected in front of the floor of the driver's seat 10, An overhead guard 12 is provided surrounding these from above.

  A front tire 2 of the forklift 1 is set and mounted with a single tire or a double tire according to a load that can be transported by a mast 6 that is a cargo handling device. In a vehicle with a single tire setting, most of the wheels 2 can be accommodated in the fender 15 set as a basic type. However, in a vehicle with a high loading load, a double tire is selected. As a result, the double tire greatly protrudes from the fender 15 set in the basic form. For this reason, in a vehicle that selects a double tire, an over fender 16 is added to a basic type of fender 15 so that most of the double tire is accommodated.

  The fender 15 and the over fender 16 cover the front wheel 2 from above and behind, the portion covering the top is formed in an inclined state where the vehicle front side is high and the rear side is low, and the portion covering the front wheel 2 from the rear is the upper end. It is located slightly in front of the vehicle and its lower end is slightly in the rear of the vehicle and is inclined slightly forward.

  The side box 4 is fixedly disposed on a vehicle body side member 17 connected to the rear of the fender 15 covering the front wheel 2. That is, the top plate 18 of the side box 4 has an upper surface that is substantially flush with the vehicle body floor, a front end connected to the fender 15, and a rear end covering the upper side of the rear wheel 3. It is fixed by. The bottom plate 19 of the side box 4 has a front end connected to the fender 15, a rear end positioned in front of the rear wheel 3, and is fixed to the lower end side of the side member 17 by welding or the like.

  The frame plate 20 of the side box 4 has a U-shaped cross-sectional shape to form the lateral wall and the back wall of the side box 4, and the lateral wall 20 </ b> A on the front side of the vehicle is directed toward the outside. The lateral wall 20B on the rear side of the vehicle is located immediately behind the fender 15 and the front side of the rear wheel 3, and the rear wall 20C is located close to the side member 17, respectively. It is fixed to the bottom plate 19 by welding or the like.

  An opening portion of the side box 4 that opens toward the outside of the vehicle body is configured to be opened and closed by a cover plate 5 that is rotatably attached to a hinge shaft 25 disposed on the bottom plate 19. The lid plate 5 is raised in a vertically standing state about the hinge shaft 25 to close the opening of the side box 4, and is tilted to a horizontal state about the hinge shaft 15 to open the opening of the side box 4. I am doing so. FIG. 1 shows a state in which the lid plate 5 is closed, and FIG. 2 shows a state in which the lid plate 5 is opened. In the closed state, the cover plate 5 is formed in a shape that forms a uniform gap behind the fender 15 beyond the lateral wall 20A disposed on the front side on the front side of the vehicle, and is disposed on the rear side on the rear side of the vehicle. It extends beyond the lateral wall 20B to just before the rear wheel 3, and its upper edge is further extended around the upper side of the rear wheel 3 and gradually extending.

  As shown in FIG. 3, the hinge shaft 25 includes a pair of hinge pins 26 and 27 fixed to the bottom plate 19, and a pair of hinge plates 28 fixed to the cover plate 5 and engaged with the hinge pins 26 and 27, respectively. 29. The hinge pin 26 positioned in front of the vehicle is fixed to the bottom plate 19 by direct welding or the like in a state of straddling a notch groove 30 provided on the bottom plate 19 from the vehicle side toward the vehicle center. The hinge pin 27 located on the vehicle rear side is fixed by welding or the like at a predetermined height position from the surface of the bottom plate 19 of the upright portion of the bracket 32 fixed to the bottom plate 19 by welding or the like.

  FIG. 4 shows a plan view and a side view of the bottom plate 19 of the side box 4. As shown in the side view, the front hinge pin 26 and the rear hinge pin 27 are set to be higher on the rear side and lower on the front side. Further, as shown in the plan view, the hinge pin 26 on the vehicle front side is arranged outside in the vehicle left-right direction, and the hinge pin 27 on the vehicle rear side is arranged inside in the vehicle left-right direction.

  The arrangement of the front and rear hinge pins 26 and 27 is such that the cover plate 5 is in a closed state when each of the hinge pins 26 and 27 is disposed in a plane where the vehicle inner side is raised by an angle of 45 degrees with respect to the bottom plate 19 when viewed from the front of the vehicle. It can be configured to be vertical and horizontal when opened. That is, the hinge pins 26 and 27 may be arranged so as to be included in a surface that is equidistant from both the closed surface and the open surface of the cover plate 5. Then, the cover plate 5 rotates around the hinge shaft 25 connecting the hinge pins 26 and 27 when opening and closing. These hinge pins 26 and 27 are both fixed so that the axial center thereof is parallel to the bottom plate 19.

  Similarly to the front hinge pin 26, the bottom plate 19 at a position corresponding to the rear hinge pin 27 is formed with a notch groove 31 provided from the vehicle side toward the vehicle center. An edge of the rear notch groove 31 on the vehicle front side is formed on an inclined surface 31A in which an outer portion in the vehicle left-right direction is located on the vehicle front side and an inner portion is located on the vehicle rear side.

  As shown in FIGS. 3 and 5, the hinge plates 28 and 29 fixed to the lid plate 5 are fixed to the vehicle front side and the rear side of the inner side surface of the lid plate 5 by welding or the like, respectively. 26 and 27A, engaging grooves 28A and 29A. These hooking grooves 28 </ b> A and 29 </ b> A are arranged so that the front side is close to the surface of the lid plate 5 and the rear side is far from the surface of the lid plate 5 on the surface at an angle of 45 degrees with respect to the surface of the lid plate 5. Forming.

  These arrangements match the positions of the hinge pins 26 and 27 arranged on the bottom plate 19 with the respective hooking grooves 28A and 29A when the cover plate 5 is closed. The opening directions of these hooking grooves 28A and 29A are also opened in the direction of an angle of 45 degrees with respect to the surface of the cover plate 5, and even when the cover plate 5 is closed, it is open. However, the engagement between the latching grooves 28A and 29A and the hinge pins 26 and 27 is advanced by the weight of the cover plate 5, that is, the hinge pins 26 and 27 are advanced to the back side of the latching grooves 28A and 29A.

  The hinge plates 28 and 29 are provided with extension portions 28B and 29B that engage with the notch grooves 30 and 31 respectively formed in the bottom plate 19, and these extension portions 28B and 29B close the lid plate 5. Regardless of whether the cover plate 5 is in an open state or in an open state, the cover plate 5 functions to regulate the lateral movement of the cover plate 5 by always engaging with the notched grooves 30 and 31 of the bottom plate 19. Further, the hinge plate 29 on the rear side of the vehicle is provided with a contact portion 29C that functions as a stopper that holds the cover plate 5 in an open state between the extension portion 29B and the hanging groove 29A. The abutting portion 29 </ b> C abuts against the back end of the notch groove 31 of the bottom plate 19 when the lid plate 5 is opened, thereby preventing further opening of the lid plate 5. In the illustrated example, the contact portion 29C is formed in a portion where a part of the hinge plate 29 is recessed.

  Although not shown in detail, as shown in FIGS. 1 and 2, a portion of the side plate 4 adjacent to the cover plate 5 of the frame plate 20 is not covered with the cover plate 5 when the cover plate 5 is closed. A buffer stopper 40 is provided to stop by contacting the inner surface side, and a lock device 41 is provided for locking the lid plate 5 in a closed state.

  In the lid opening / closing device having the above configuration, the hooking grooves 28A and 29A provided in the front and rear hinge plates 28 and 29 of the lid plate 5 are respectively associated with the front and rear hinge pins 26 and 27 provided in the bottom plate 19 of the side box 4. By combining, it can be assembled. At the time of this assembly, the cover plate 5 is held in a half-open state, so that the direction of the hooking grooves 28A and 29A provided in the hinge plates 28 and 29 is set downward, and the positions of the hinge pins 26 and 27 are confirmed. By engaging the latching grooves 28A and 29A with the hinge pins 26 and 27, it can be assembled easily.

  In the state where the cover plate 5 is closed, as shown in FIG. 2, the edge of the cover plate 5 on the vehicle front side is located along the rear surface of the fender 15, and the upper edge of the cover plate 5 is the edge of the top plate 18. The edge of the cover plate 5 on the vehicle rear side is located along the front and upper side of the rear wheel 3. In this state, as shown in FIGS. 6 and 7, the cover plate 5 is in a region that is substantially hidden behind the fender 15, and the hinge plates 28 and 29 of the cover plate 5 are vertically moved as shown in FIG. 3. Upright in the direction. The extension portions 28B and 29B of the hinge plates 28 and 29 are partially engaged with outer portions of the notch grooves 30 and 31 provided in the bottom plate 19 of the side box 4 in the vehicle left-right direction. That is, the extension portions 28B and 29B are in contact with the front edge of the cutout grooves 30 and 31, and by this contact, the further movement of the lid plate 5 toward the front of the vehicle is prevented. Contact between the front edge of the cover plate 5 and the fender 15 is prevented.

  When the lock device 41 is removed from this state and the cover plate 5 is opened to the front, the cover plate 5 rotates to the front with the hinge shaft 25 connecting the front and rear hinge pins 26 and 27 as the central axis. At this time, since the front hinge pin 26 is located on the lower side on the front side and the rear hinge pin 27 is located on the upper side on the back side, the lid plate 5 and the hinge plates 28 and 29 are rotated obliquely rearward. By this rotation, the front end of the cover plate 5 is rotated while being separated from the back surface of the fender 15. By this rotation, the extended portions 28B and 29B of the hinge plates 28 and 29 are inclined rearward of the vehicle in the notched grooves 30 and 31 of the bottom plate 19, and the extended portions 29B of the rear hinge plate 29 are hinge pins 27. Since the distance to is large, it penetrates toward the back of the groove 31. Inclination and intrusion of the extension portion 29B on the rear side is such that the inner end of the extension portion 29B in the left-right direction of the vehicle abuts the edge 31A on the vehicle front side of the notch groove 31, and the notch groove slides along this edge 31A. 31, the cover plate 5 is opened while urging the hinge plate 29 and the cover plate 5 toward the vehicle rear side.

  When the cover plate 5 is further opened, the contact portion 29C provided on the rear hinge plate 29 contacts the inner edge of the rear notch groove 31 to prevent further opening, and the cover plate 5 is fully opened. It becomes a state. 8 to 10 show a state where the cover plate 5 is fully opened. In the fully opened state, the inner side surface of the lid plate 5 is the upper surface, and a part of the lid plate 5 enters under the bottom plate 19 of the side box 4. As shown in FIG. 8, the cover plate 5 is inclined toward the vehicle rear side, and the hinge plates 28 and 29 that are integrated with the lid plate 5 are also inclined toward the vehicle rear side. These tilt movements can also avoid interference with the over fender 16 positioned in front of the vehicle.

  As described above, the lid opening / closing device in the present embodiment is an opening / closing device for the lid 5 that is opened / closed around the horizontally installed hinge shaft 25, and any one of the openings closed by the lid 5. The hinge shaft 25 disposed adjacent to one edge is disposed so as to be inclined with respect to the edge and / or with respect to the distance from the opening surface of the end of the hinge shaft 25 on the side close to the edge to the back side. By disposing the distance from the opening surface at the end of the hinge shaft 25 on the side that is lifted with respect to the edge of the opening to the far side, the over fender 16 Without changing the shape of the interference object, for example, by reducing the shape of the over fender 16 or the like. Large enough to look good Etc. to over fender 16, it is possible to exhibit sufficient functions. On the contrary, the lid plate 5 does not need to be formed small in anticipation of interference with the interference object, so that the degree of freedom in design can be improved and the shape can be improved.

  In the case of a general example (not shown) in which hinge pins provided in the vicinity of the bottom plate 19 are arranged on the same axis parallel to the edge of the bottom plate 19, the lid plate rotates about its axis, so that the lid plate is opened. In any one of the steps, the front edge of the cover plate interferes with the over fender, and the cover plate cannot be further opened. For this reason, it is necessary to remove the over fender from the fender before opening the cover plate, and to open the cover plate on the over fender, which reduces the efficiency of vehicle maintenance work. However, in the lid opening / closing device of this embodiment, it is not necessary to remove the over fender 16 when the lid plate 5 is opened / closed, so that the maintenance work efficiency in the vehicle with the over fender 16 can be improved.

  The arrangement of the front and rear hinge pins 26 and 27 needs to be arranged in a direction in which the turning trajectory of the edge of the cover plate 5 is away from the interference object. For example, when there is an interference object on the vehicle rear side, the front The hinge pin 26 on the side may be a high position on the back side of the bottom plate 19, and the hinge pin 27 on the rear side may be a low position on the near side of the bottom plate 19. Although not shown, when the cover plate is opened around its upper edge, if there is an interference object on the front side, the front hinge pin is placed high and on the near side, and the rear It is only necessary to place the hinge pin on the back side at a lower position, and conversely, if there is an interference object on the rear side, the hinge pin on the front side is placed lower and on the back side, and the hinge pin on the rear side is What is necessary is just to arrange | position to a near and high position.

  Further, since the hinge plates 28 and 29 (extension portions 28B and 29B) and the notched grooves 30 and 31 provided in the member (bottom plate 19) provided with the hinge pins 26 and 27 are engaged, The clearance between the width of the hinge plates 28 and 29 that rotate while tilting and the width of the cutout grooves 30 and 31 can be reduced as the cover plate 5 is opened, and rattling of the cover plate 5 in the vehicle front-rear direction at the time of opening is suppressed. it can. Although not shown, in the case of a general example in which hinge pins provided in the vicinity of the bottom plate are arranged on the same axis parallel to the edge of the bottom plate, the lid plate rotates around the axis, so the lid body The width of the hinge plate does not change.

  Further, since the hinge plates 28 and 29 (extension portions 28B and 29B) enter the back side from the entrance side of the notch grooves 30 and 31 as the cover plate 5 is opened, the interference of the notch grooves 30 and 30 is caused. By forming either one of the edges in the front-rear direction on the side where the object is present with the inclined surface 31A having a large width on the entrance side and a small width on the back side, the lid plate 5 is made to be inclined with respect to the inclined surface 31A. For example, a gap between the cover plate 5 and the over fender 16 can be secured when the cover plate 5 is opened or closed.

  In addition, since the hinge pins 26 and 27 with which the hooking grooves 28A and 29A of the hinge plates 28 and 29 of the cover plate 5 engage are arranged in parallel to the bottom plate 19, the hinge shaft formed by the hinge pins 26 and 27 is formed between them. Even if 25 is inclined, it is possible to prevent the cover plate 5 from moving downwardly with respect to the inclined hinge shaft 25.

  The hooking grooves 28A and 29A provided on the hinge plates 28 and 29 are arranged obliquely upward so that the hinge pins 26 and 27 are moved to the back side of the hooking grooves 28A and 29A when the weight of the cover plate 5 is added. Therefore, the cover plate 5 does not fall off the hinge pins 26 and 27 during opening and closing.

  Further, since the inner edge of the notch groove 31 provided in the bottom plate 19 and the hinge plate 29 are brought into contact with each other in the opened state of the cover plate 5, it is possible to omit providing a stopper for the cover plate 5 separately.

  In the above embodiment, the cover plate of the side box 4 on the side surface of the vehicle body avoids the interference with the over fender 16 as the interference object, but the front end of the cover plate 5 is not shown. Alternatively, the rear end may avoid interference with other interference objects.

  Moreover, in the said embodiment, although the lid plate 5 demonstrated what opened to the near side centering on the hinge axis | shaft 25 provided in the lower part side, although not shown in figure, it is centered on the hinge axis | shaft provided in the upper side of the lid plate. It may be one that opens to the upper side in front, or it may be a lid plate that is substantially horizontal when closed and the lid plate opens in the vertical direction about the hinge axis or 180 degrees in the opened state. These lid plates are usually referred to as “hatch”.

  Further, in the above embodiment, the hinge shaft 25 is inclined with respect to the opening edge and is located at the edge of the opening with respect to the distance from the opening surface of the hinge shaft end closer to the opening edge to the back side. Although the description has been given of the arrangement in which the distance from the opening surface of the hinge shaft end on the lifting side to the back side is increased, although not shown, the hinge shaft is provided so as to be inclined with respect to the opening edge. Or from the opening surface of the hinge shaft end on the side that is lifted with respect to the edge of the opening with respect to the distance from the opening surface of the hinge shaft end on the side close to the opening edge to the back side. You may arrange | position by increasing the distance to the back side.

  In the present embodiment, the following effects can be achieved.

  (A) a closed state that can be rotated around a hinge shaft 25 that is disposed horizontally in proximity to any edge of the opening, and that is rotated around the hinge shaft 25 and overlaps the opening; An opening and closing device for the lid body 5 that is opened and closed to open to open the opening, and at least one of both shaft ends of the hinge shaft 25 is offset in a plane perpendicular to the edge to the edge. The hinge shaft 25 is inclined and / or at least one of both shaft ends of the hinge shaft 25 is offset in a direction perpendicular to the opening surface of the opening portion closed by the lid 5 with respect to the opening surface. The hinge shaft 25 was inclined.

  Therefore, the trajectory of the lid 5 when it is opened can be tilted, and the lid 5 can be pivoted away from the interference object such as the over fender 16. It is sufficient to reduce the shape of the over fender 16 that is the interference object, such as reducing the shape of the interference object without changing the shape of the interference object, and to make the interference object such as the over fender 16 having a sufficient size and good appearance. Function can be demonstrated. On the contrary, the lid 5 does not need to be formed small in anticipation of interference with the object to be interfered with, so that the degree of freedom in design can be improved and the shape can be improved.

  (A) Hinge plates 28 and 29 coupled to the lid 5 and connected to the hinge shaft 25 are disposed near both ends of any one edge of the opening to engage with the hinge shaft 25, and A part is engaged with each of the notch grooves 30 and 31 provided in the vicinity of both ends of one edge, and the engaging part with respect to the notch grooves 30 and 31 is moved according to the opening / closing position of the lid 5. Then, at least one edge of the notch groove 31 with which the hinge plate 29 that engages with the opening or the hinge shaft portion on the side away from the opening surface is inclined 31A with respect to the movement locus of the hinge plate 29 Let me configure it.

  For this reason, the clearance between the width of the hinge plates 28 and 29 and the width of the notched grooves 30 and 31 can be reduced as the lid plate 5 is opened, and rattling of the lid plate 5 at the time of opening can be suppressed. Moreover, the lid plate 5 can be moved away from the interference object by the inclined surface 31A as it is opened, and for example, a gap with the over fender 16 when the lid plate 5 is opened and closed can be secured.

  (C) Since the hinge shaft 25 is arranged only in the vicinity of each shaft end and fixed to each other, the shafts 26 and 27 are parallel to each other and also to the opening surface and one edge. Even if the hinge shaft 25 formed by the hinge pins 26 and 27 is inclined, it is possible to prevent the cover plate 5 from moving downwardly with respect to the inclined hinge shaft 25.

  (D) The hinge plates 28 and 29 are engaged with the hinge shaft 25 by the hanging grooves 28A and 29A having one end opened, and the hinge shaft 25 is engaged with the rear side of the hanging grooves 28A and 29A by the weight of the lid 5. Since the open ends of the hooking grooves 28A and 29A are arranged in the direction to be moved, the cover plate 5 does not fall off the hinge pins 26 and 27 when opening and closing.

  (E) The lid 5 is brought into contact with the hinge plate 29 by the contact of the edge on the back side of the notch groove 31 with which the hinge plate 29 that engages with the hinge shaft 27 on the side away from the opening or the opening surface. In order to restrict the fully open position, it is possible to omit providing a stopper for the cover plate 5 separately.

  (F) As the lid 5, an opening directed toward the vehicle body side of the side box 4 provided on the vehicle body side side connected to the rear of the fender 15 covering the front wheel 2 of the industrial vehicle from the rear and above is provided below the opening portion. It opens and closes around a hinge shaft 25 provided in the vicinity of the edge, and the edge of the lid 5 on the front side of the vehicle is formed in a shape along the fender 15 so that the degree of freedom of design for a vehicle with an over fender 16 is achieved. Will increase.

  In the present invention, the side box 4 of the forklift 1 as an industrial vehicle is taken as an example, and the cover 5 of the side box 4 on the side surface of the vehicle body avoids interference with the over fender 16 as an interference object. The front end or the rear end of the plate 5 may avoid interference with other interference objects. Further, the cover plate 5 is described as being open to the front side with the hinge shaft 25 provided on the lower side thereof as the center. However, the cover plate 5 is open to the upper side with respect to the hinge shaft provided on the upper side of the cover plate. The cover plate may be a substantially horizontal state in the closed state, and the cover plate may be a cover plate that opens in the vertical direction around the hinge axis or 180 degrees in the open state.
