In the hinge member mounting structure shown in each of the above patent document has the following problems.
In the case of the structure described in Patent Document 1, there is a problem that the inverted U-shaped mounting seat is liable to have burrs at the lower end during manufacturing, and the burrs bite into the litter and are damaged. Tilt member is generally being anodized for corrosion protection, can lead to corrosion peeling alumite film by biting of the mounting seat, it tends to cause the mounting bolts loose. In addition, since the contact area between the inverted U-shaped mounting seat and the tilt is small, there is a risk that stress will concentrate on the contact area during impact when the tilt is opened, and cracks may occur. The wall thickness tends to increase and the weight increases.

On the other hand, in the case of the structure described in Patent Document 2, it is assumed that the problem of biting in is similar to that described in Patent Document 1, but since the restrained area is small, as a measure against stress concentration, an increase in thickness, weight It tends to increase.
In the case of the structures described in Patent Document 3 and Patent Document 4, it is necessary to drive a wedge piece or to fix it to the inner wall of the tilt.

  The present invention has been made in view of the above circumstances, and does not damage the open / close panel such as the tilt, and increases the restraint area to prevent local stress concentration and increase the wall thickness. It is an object to provide an attachment structure that can be firmly fastened and easy to handle.

  The present invention is an opening / closing panel mounting structure for a truck bed, in which an end of an opening / closing panel is attached to an end of a rotatable hinge piece of a hinge member fixed to the loading platform, A groove is formed along the length direction, and a pair of ridges projecting in directions facing each other so as to narrow the opening are formed along the length direction of the groove on the inner surface of the groove. A support plate is provided at the end of the hinge piece so as to straddle between the ridges from the outside of the groove, and is wider than the opening between the ridges inside the groove. The slide bar is movably provided in the length direction of the groove, and the support plate and the slide bar are fastened by a bolt in a state where the convex portion is sandwiched from the front and back, and the convex portions are opposed to each other. The surface is in the thickness direction A taper surface that is inclined in a direction that gradually narrows the interval from one side to the other along one side, and a protrusion that fits between the taper surfaces is formed on either the support plate or the slide bar, and the slide bar The groove portion is formed along the length direction on the surface opposite to the contact surface with the protruding strip portion, and the head portion of the bolt or a nut member screwed to the bolt is provided in the groove portion. It is stored in a state of being prevented from rotating by a wall surface.

In this mounting structure, a pair of ridges arranged on both sides of the groove are sandwiched from both the front and back surfaces by a support plate and a slide bar, and the protrusions provided on one of these support plates or slide bars are both ridges. Since it fits between the taper surfaces of a part, it contacts closely from the front and back both surfaces of a protruding item | line part to a taper surface. This open / close panel is repeatedly opened and closed on the truck bed. Even in the open state, the open / close panel is susceptible to external forces due to contact with forklifts, etc. during cargo loading / unloading operations, and the external force is spaced between the two ridges. However, since the support plate and the slide bar are in close contact with the front and back surfaces of these ridges and the opposing surfaces of both ridges, the restraint area increases, and therefore The stress when an external force is applied can be dispersed, and a firm attachment structure can be reliably maintained. In addition, since it is in surface contact, there are few inconveniences such as damaging the open / close panel.
In addition, the open / close panel can be attached to the hinge piece by simply holding the ridge portion between the slide bar and the support plate and fastening it, and the bolt head or nut member is prevented from rotating in the groove portion of the slide bar. because it is housed in a state, it is possible to facilitate the fastening work, mounting workability is good.
Further, the slide bar can be manufactured by an extruded shape member made of aluminum, and the contact state with the open / close panel can be smoothed to prevent the occurrence of scratches more reliably.

In the opening / closing panel mounting structure of the truck bed according to the present invention, the projecting portions that engage with each other between the projecting ridge portions and either the support plate or the slide bar that contacts the projecting ridge portions; it may have been provided by at least one pair on either side and the recess through the opening.
By fastening with the recesses and the projections engaged, it is possible to more reliably prevent the projections from opening even when an external force acts in the direction of opening the gap between the two projections as described above. And the attachment state can be maintained further firmly.

In the opening / closing panel mounting structure for a truck bed according to the present invention, the opening / closing panel may be formed of an aluminum extruded shape having the length direction of the groove as an extrusion direction.
The groove can be accurately formed by extrusion molding, and the hinge piece can be firmly fixed at an arbitrary position in the length direction of the groove.

  According to the opening / closing panel mounting structure for a truck bed according to the present invention, the both ridges of the groove of the opening / closing panel are sandwiched between the support plate and the slide bar, and at that time, the support plate or the slide is sandwiched between the taper surfaces of the ridges. Since the protrusions of the bar are closely fitted, the restraint area with respect to the open / close panel is increased, the stress when an external force is applied can be dispersed, and a firm attachment structure can be reliably maintained. Therefore, it is possible to provide a strong mounting structure without increasing the wall thickness of the open / close panel and the like, and it can be fixed by simply tightening the projecting ridge portion in the sandwiched state, and the bolt head. Since the portion or the nut member is prevented from rotating in the groove portion of the slide bar, the mounting operation is easy, and since the surface contact is made, there are few problems such as scratching the open / close panel.

The open / close panel of the present invention can be applied to the tilt 7, the wing 8 and the door 10 among the components of the loading platform 2, and has a feature in the attachment structure of the hinge member for opening and closing them. .

Below, 1st Embodiment which took the tilt 7 as an example as an opening-and-closing panel is described.
As shown in FIG. 9, the tilt 7 is connected to the top rail 11, the two middle rails 12, and the bottom rail 13 by connecting both ends of the width direction to each other. It is configured as a single panel. Each of these rails 11 to 13 are all formed by aluminum extrusions. Reference numeral 14 in FIG. 9 denotes a fitting portion between the rails 11 to 13.
Then, the tilt 7, the lower end of the bottom rail 13, by the rotatable one of the hinge pieces 17 in the hinge member 16 fixed to the floor 15 of the cargo bed 2 is mounted, the entire tilt 7 As shown in FIG. 6, it opens and closes between a position erected vertically on the side surface of the floor 15 of the loading platform 2 and a position where the top rail 11 faces downward as it is tilted from the side surface of the floor 15 as shown in FIG. 8. Can be done. Moreover, the whole standing posture shown in FIG. 6 is shown in FIG. 9, and in this state, the lower end portion of the wing panel 6 is superposed on the outer side of the upper end portion of the top rail 11.

  As described above, the bottom rail 13 of the tilt 7 is formed by an extruded shape member made of aluminum. As shown in FIG. 5 and the like, the outer wall portion 21 and the inner wall portion 22 are mutually connected by a plurality of connecting plate portions 23. It is formed in the hollow integral shape connected to. At the lower end portion of the bottom rail 13, the outer wall portion 21 and the inner wall portion 22 are in a protruding state, and a groove 24 is formed between the opposed inner surfaces of the outer wall portion 21 and the inner wall portion 22. A pair of ridges 25 project at right angles at the same height on the inside. These ridges 25 are formed along the length direction of the bottom rail 13, and the end surfaces of both ridges 25 are opposed to each other, so that the opening 24a of the groove 24 is formed between the opposed surfaces. Forming. Accordingly, the groove 24 has a substantially square cross section, a part of the side of the square is opened by the opening 24 a, and is formed over the entire length between both end faces of the bottom rail 13. Further, as shown in FIG. 2, the front end surfaces of the two ridges 25 face each other between the two ridges 25 from the inside to the outside of the groove 24 (from the inside of the groove 24 toward the lower end of the tilt 7). The tapered surface 26 is inclined in the direction of gradually decreasing the interval. In addition, a rib-like convex portion 27 that slightly protrudes upward is formed along the length direction at the tip of the upper surface 25a of the convex portion 25.

In this case, the dimensions of the rails 11 to 13 are not particularly limited, but the thickness of the entire rail (the dimension between the outer surface of the inner wall surface and the outer wall surface) is, for example, 25 to 35 mm, both ends in the height direction. The distance between the parts is 150 to 250 mm, and the thickness of each part is 1 to 4.5 mm.
Further, the thickness T of the ridge portion 25 shown in FIG. 2 is formed to be 2 to 4.5 mm, for example, and up to a position where H = 0.5 mm is raised from the outer surface (lower surface in FIG. 2) 25b of the ridge portion 25. An annular portion 28 having a straight shape, a convex arc shape, or a combination thereof is formed, and a tapered surface 26 inclined upward at an inclination angle θ is formed above the annular portion 28. In this case, the minimum value of the inclination amount X is 0.3 mm, and the maximum value is (TH) / 2. When T = 2 to 4.5 mm, the inclination angle θ is in the range of 4 to 27 °. Become. The corner portion of the annular portion 28 is chamfered with a curved surface having a radius R of about 0.3 mm. The annular portion 28 is formed so as not to be a sharp edge between the tapered surface 26 and the outer surface (lower surface) 25b of the ridge portion 25 so as to ensure strength and prevent wear or the like.

  On the other hand, the hinge member 16 is rotatably connected to a hinge piece 31 fixed to the outer surface of the floor 15 of the loading platform 2 and a hinge shaft 32 along the length direction of the loading platform 2 to the hinge piece 31. A hinge plate 17 is formed, and a belt-like support plate 33 is integrally provided at the tip of the rotatable hinge piece 17. The width direction of the support plate 33 is perpendicular to the turning radius of the hinge piece 17, in other words, in the tangential direction of the turning locus, and the width dimension of the hinge piece 17 (the length direction of the loading platform 2). 7), and is arranged so that both end portions thereof protrude beyond the hinge piece 17, as shown in FIG.

  Further, as shown in FIG. 1, the support plate 33 is formed in a band plate shape that is wider than the opening 24 a between the protrusions 25 at the lower end of the bottom rail 13. As described above, since the width direction of the support plate 33 is oriented in a direction perpendicular to the turning radius of the hinge piece 17, the surface of the support plate 33 is always in the radial direction regardless of the turning position of the hinge piece 17. It looks to the outside.

On the other hand, a slide bar 41 is provided inside the groove 24 of the bottom rail 13. The slide bar 41 is formed in the shape of a square rod having a width that is larger than the opposing spacing of the two ridges 25 as a whole, and as shown in FIG. A projecting portion 43 formed integrally with the entire length is formed on the lower surface side opposite to the groove portion 42 and formed by raising the central portion in the width direction. The groove 42 is formed in a rectangular shape in cross section, and the bottom surface 42a and the inner surfaces of both side walls 42b are formed as flat surfaces.
The protrusion 43 is fitted between the two ridges 25 when the slide bar 41 is brought into contact with the two ridges 25 in the groove 24 of the bottom rail 13. Both side surfaces are formed as tapered surfaces 44 inclined at the same angle as the ridges 25. Further, the height h of the protruding portion 43 is slightly smaller than the thickness T of the protruding portion 25, for example, is formed to be smaller by the height H of the annular portion 28, and the protruding portion 43 is fitted between the protruding portions 25. When combined, the distal end surface of the protrusion 43 has a dimensional relationship that is disposed between the two ridges 25 without exceeding the lower surface 25 b of the ridge 25.

In addition, the portion of the slide bar 41 that protrudes on both sides of the protrusion 43 comes into contact with the upper surface 25 a of the protrusion 25 when the protrusion 43 is fitted between the protrusions 25, and the protrusion A groove-like concave portion 45 that engages with the convex portion 27 at the tip of the portion 25 is formed along the length direction.
Thereby, when the slide bar 41 is brought into contact with the upper surface 25a of the both ridges 25, the projection 43 of the slide bar 41 is fitted between the tapered surfaces 26 of the both ridges 25 as shown in FIG. On both sides of the projection 43, the projection 27 of the projection 25 is engaged with the recess 45 of the slide bar 41. In this state, the groove 42 of the slide bar 41 is in the opposite direction to the projection 25 (FIG. 1). In a state of being directed upward).
As shown in FIG. 2, the convex portion 27 on the upper surface of the convex strip portion 25 is formed in a gently convex curved surface, and the concave portion 45 of the slide bar 41 corresponding thereto has the same radius of curvature as the convex portion 27. It is formed on a concave curved surface with a slightly larger radius of curvature.

  The length of the slide bar 41 is sufficiently long in the length direction of the groove 24 of the bottom rail 13, specifically, substantially the same length as the support plate 33. A through hole 46 is formed in the bottom surface 42 a of the groove 42. The hexagonal head portion 48 of the bolt 47 inserted into the through hole 46 is arranged in the groove portion 42. In this case, the distance between the inner surfaces of the side walls 42 b of the groove portion 42 and the bolt 47. The difference between the distance between both side surfaces 48a of the head portion 48 is small, and when the head portion 48 of the bolt 47 is rotated in the groove portion 42, it comes into contact with both side walls 42b of the groove portion 42 and is prevented from rotating. ing. In FIG. 1 and the like, reference numeral 49 indicates a nut member with a flange that is screwed into a tip end portion of a bolt 47 that passes through the through hole 46 of the slide bar 41 and the through hole 33a of the support plate 33.

At the lower end of the bottom rail 13, as described above, the support plate 33 comes into contact with the lower surfaces 25 b of the two ridges 25, while the slide bar 41 in the groove 24 has the ridges 25. Similarly, the upper surface 25a is in contact with the upper surface 25a so that the concave portion 45 and the convex portion 27 of the convex portion 25 are fitted, and the protruding portion 43 is fitted between the tapered surfaces 26 of the convex portions 25, Bolts 47 accommodated in the through holes 46 of the slide bar 41 are inserted into the through holes 33a of the support plate 33 via the gaps between the two ridges 25, and are attached to the tip portions of the bolts 47 protruding from the support plate 33. When the nut member 49 is screwed together, these are fastened in a state where both the protruding strips 25 are sandwiched between the support plate 33 and the slide bar 41. Thus, the tilt 7 including the bottom rail 13 is integrally attached to the tip of the hinge piece 17.
In addition, in FIG. 6 etc., the code | symbol 50 shows the bottom cover attached to the lower end part of the bottom rail 13, and covering so that the outer side of the support plate 33 may be enclosed.

  When attaching the tilt 7 to the hinge member 16 in such an attachment structure, first, the hinge piece 31 of the hinge member 16 is fixed to the side surface of the floor 15 of the loading platform 2 prior to the attaching operation of the tilt 7. Then, the slide bar 41 is inserted into the groove 24 of the bottom rail 13 of the tilt 7 from the end surface in the length direction of the bottom rail 13. At this time, the bolts 47 are accommodated in the two through holes 46 of the slide bar 41, and the heads 48 are engaged in the grooves 42 of the slide bar 41. When the slide bar 41 is inserted into the groove 24 of the bottom rail 13, the convex portion 27 of the convex portion 25 engages with the concave portion 45 of the slide bar 41, and the protruding portion 43 of the slide bar 41 is formed on both convex portions. It will be in the state fitted between the taper surfaces 26 of the part 25. FIG. Moreover, the volt | bolt 47 will be in the state protruded via between both the protruding item | line parts 25 (refer FIG. 4).

On the other hand, the support plate 33 of the hinge piece 17 in the hinge member 16 is brought into contact with the lower surface 25b of the both ridges 25 of the bottom rail 13, and the slide bar 41 is moved in the groove 24 to a position corresponding to the support plate 33. When the nut 47 is inserted by inserting the end of the bolt 47 from the through hole 33a of the support plate 33 and screwing the nut member 49, the protrusion 43 of the slide bar 41 bites between the tapered surfaces 26, The ridge portion 25 is clamped between the slide bar 41 and the slide bar 41. At this time, a gap is formed between the front end surface of the protrusion 43 of the slide bar 41 and the upper surface of the support plate 33, and the protrusion 43 is tightly connected between the tapered surfaces 26 of the ridges 25. It will be in the state which touched.
In this way, the slide bar 41 is disposed in the groove 24, and the tilting 7 can be fixed to the hinge piece 17 only by fastening the protruding portion 25 with the support plate 33 in a sandwiched state. Workability is good.
Further, when the slide bar 41 is slid in the groove 24, the protrusion 43 moves in a state of being fitted between the ridges 25, so the position of the slide bar 41 in the width direction in the groove 24. Is stable, and positioning with the support plate 33 is easy.

The tilt 7 having such a mounting structure is tilted as shown in FIG. 8 by the hinge member 16 so that the top rail 11 faces vertically downward as shown in FIG. It can be opened and closed to the position.
In the opening / closing operation, an external force may act on the attachment portion between the tilt 7 and the hinge piece 17. For example, during the performance of cargo unloading operations to and from the loading platform 2 in the state shown in FIG. 8, a large external force when the tilt 7 in contact with a forklift or the like as shown by the solid line arrow is pressed acts However, in this attached state, the bottom rail 13 is fastened with the two ridges 25 sandwiched between the support plate 33 and the slide bar 41 at the lower end (facing upward in FIG. 8). In the fastening portion, the protrusion 43 of the slide bar 41 is fitted between the tapered surfaces 26 of the two ridges 25, and the protrusion 27 of the ridge 25 is engaged with the recess 45 of the slide bar 41. The support plate 33 and the slide bar 41 are in contact with each other over a wide area from the upper surface 25a of the ridge 25 to the tapered surface 26 and the lower surface 25b. Therefore, the stress generated in the fastening portion due to the external force is dispersed, and the occurrence of looseness is surely prevented, and the engagement between the concave portion 45 and the convex portion 27 prevents the both convex ridge portions 25 from spreading, which is strong. The mounting structure can be maintained.

FIG. 11 shows an example in which the mounting structure of the present invention is applied to a wing. Further, FIG. 12 shows an example of applying the mounting structure of the present invention to the rear of the door.
In FIG. 11, reference numeral 51 denotes a wing rail provided at the end of the wing 8, and is a hollow in which the outer wall portion 52 and the inner wall portion 53 are mutually connected by a connecting plate portion 54 by an extruded shape member made of aluminum. It is formed in an integral shape.

In FIG. 12, reference numeral 55 denotes a door frame provided at the end of the door 10, and similarly, an extruded shape member made of aluminum is used between the outer wall portion 56 and the inner wall portion 57 by a connecting plate portion 58. It is formed in a hollow integrated shape that is interconnected.
The wing rail 51 and the door frame 55 are also formed with grooves 24 and ridges 25 similar to the bottom rail 13 of the tilt 7 described above. The shapes of the grooves 24 and the ridges 25 are substantially the same as in the case of the bottom rail 13, and the support plate 33 and the slide bar 41 have the same shapes as in the previous embodiment. Accordingly, the attachment structure of the wing rail 51 to the ceiling beam 5 by the hinge member and the attachment structure of the door frame 55 to the rear frame 9 by the hinge member are the same as those in the previous embodiment. , the same reference numerals are applied to parts common to the components of the previous embodiment, and a description thereof will be omitted.
Thus, the mounting structure of the present invention can be applied to the mounting structures of the wing 8 and the doors 10 in addition to the tilt 7, and the opening / closing panel of the present invention includes these tilts, wings and doors. Shall be included.

On the other hand, FIG. 13 shows a second embodiment of the mounting structure of the present invention.
In the first embodiment, the taper surfaces of the two ridges are inclined in the direction of gradually narrowing the interval from the inside to the outside of the groove. However, in the embodiment of FIG. The inclination direction of the surface 26 is reverse, and the surface 26 is inclined in the direction of gradually narrowing the interval from the outside toward the inside. A protrusion 43 that fits between the tapered surfaces 26 is provided on the support plate 61. Further, the convex portion 27 and the concave portion 45 that are engaged with each other when the projection portion 43 and the tapered surface 26 are fitted to each other are also disposed between the support plate 61 and the lower surface 25 b of the convex strip portion 25. . Therefore, the lower surface of the slide bar 62 is formed as a flat surface that comes into contact with the flat upper surface 25 a of the ridge portion 25. Reference numerals 61a and 62a denote through holes of the support plate 61 and the slide bar 62, respectively.
In FIG. 13, parts common to the constituent elements of the previous embodiment are given the same reference numerals and description thereof is omitted.

  Also in this mounting structure, the support plate 61, the slide bar 62, and the two ridges 25 are in contact over a wide area from the upper surface 25a of the ridge 25 to the tapered surface 26 and the lower surface 25b, and stress is applied to the external force. It can be dispersed and maintain a strong mounting structure.

  FIG. 14 shows a third embodiment of the present invention. In the above-described embodiment, the head portion of the bolt is disposed in the groove portion of the slide bar to prevent the rotation. However, in this third embodiment, the bolt 47 is inserted from the support plate 33 side and the groove portion of the slide bar 41 is inserted. The nut member 49 is screwed into the nut member 49 in the inner surface 42, and the nut member 49 is prevented from rotating in the groove portion 42 of the slide bar 41. In this case, when the slide bar 41 is disposed in the groove 24 of the bottom rail 13, the height from the upper surface 25a of the ridge 25 to the upper ends of both side walls 42b of the groove 42 is from the upper end of the both side walls 42b to the bottom rail. The dimensional relationship in which the distance to the connecting plate portion 23 disposed above the 13 grooves 24 is smaller than the height of the nut member 49, in other words, as shown by the two-dot chain line in FIG. Even if the nut member 49 is loosened from the bolt 47 and hits the connecting plate portion 23 of the bottom rail 13, the dimensional relationship may be set so that it does not come off between the connecting plate portion 23 and the upper ends of both side walls 42b. Other configurations are the same as those of the second embodiment of FIG. 13, and the same reference numerals as those of the second embodiment are given and description thereof is omitted.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
