Specifically, the rear flap device and the rear flap device are provided so that the rear flap can be attached and detached independently of the side flap and can be attached to and detached from the cargo bed with the rear flap attached to the rear flap. The present invention relates to a truck bed structure.

When transporting loads such as felled trees on the bed of a vehicle such as a truck, the loadable capacity (volume) increases. be. As a result, it is possible to prevent the load such as felled trees from falling and from colliding with or interfering with the surroundings.

When attaching this plate to the loading platform, there are many cases where the loading plate is simply leaned against the flap of the loading platform. In such a mode of use, it is possible to easily attach and detach the insert plate when loading and unloading. Not only does it move during work and interfere with work, but it is also dangerous because the insert plate falls down and hits the worker.

For this reason, as described in Patent Document 1, for example, an insert frame panel placed on the upper end surface of the rear flap and the side flap of the loading platform and the upper and lower ends of the insert frame panel are clamped and fixed. A "insert frame panel fixture" has been proposed that consists of a fixture that

These fixtures consist of an upper end panel fixture that clamps and fixes the upper end of the insert frame panel attached to the side flap, and a lower end of the insert frame panel that clamps the upper ends of the rear flap and the side flap and holds the upper edges of the insert frame panel. It consists of a tilt panel fixture that clamps the part.

As a result, the gate panel fixture is fixed to the upper ends of the side gate plate and the rear gate plate, and the upper end panel fixture is mounted horizontally between the upper ends of the insert plates attached to the side gate plates. It is possible to suppress the falling off of the insert plate attached to the side flap. In addition, the insert frame panel can be reliably fixed to the flap of the loading platform and stably erected, and attachment and detachment can be easily performed on site.

Patent No. 6178956

Here, the "insert frame panel fixture" described in Patent Document 1 is such that when the insert plate is attached to the loading platform, the flap panel fixtures are attached to the upper ends of the side flaps and the rear flaps. After inserting the insert plate and fixing the lower part of the insert plate to the side and rear flaps, attach the upper end panel fixture so that it spans between the upper ends of the two insert plates attached to the sides. , the insert plate is fixed on the side flaps and the rear flaps.

However, in order to attach the insert plate to the side flaps and the rear flap using this insert frame panel fixture, first, the flap panel fixtures are attached to the side flaps and the rear flap, and then the insert plate is attached to the flap panel. The procedure is to attach it to the fixture, and then fix the upper end of the insert plate attached to the side flap with the upper end panel fixture. For this reason, there are many processes for attaching the insert plate, which is time-consuming. In addition, when the flap panel fixtures are attached to the side flaps and the rear flaps with bolts or the like, additional bolt mounting is required.

Also, when removing the insert plate, the same work occurs in the reverse order of the installation. That is, remove the upper end panel fixture from the upper end of the insert plate attached to the side flap, remove the insert plate attached to the side flap and the rear flap, and attach it to the upper edge of the side flap and the rear flap. It is necessary to remove the flap panel fixture, and there are many processes for removing the insert plate, which is time-consuming.

Also, with this insert frame panel fixture, the side insert frame panel and the rear insert frame panel are in contact with each other. There is a danger of falling, such as detaching from the side tilt plate.

The present invention has been devised in view of the above points. The rear insert plate (corresponding to the rear insert frame panel) can be attached and detached independently of the side insert plate (corresponding to the side insert frame panel). To provide a rear flap device which can be attached to and detached from a truck bed with a rear flap attached to the rear flap and a truck bed structure provided with the rear flap device.

In order to solve the above-mentioned problems, the rear flap device of the present invention includes a rear flap having a predetermined height and capable of substantially closing a rear opening of a loading platform; A trailing plate holding frame capable of holding a trailing plate formed higher than the plate; and a rear flap plate attachment portion for detachably attaching the rear flap plate to the portion.

Here, when the rear flap is attached to the rear of the truck with a rear flap that has a predetermined height and can substantially close the rear opening of the truck, the rear flap of the truck is substantially closed, thereby It is possible to prevent the load from falling from the rear opening when the load is loaded on the rear opening.

In addition, when the trailing plate is attached to the trailing plate holding frame by the trailing plate holding frame which is formed higher than the trailing plate and is capable of holding the trailing plate, at least the rear fanning plate and the trailing plate are separated. In either of the cases where the lowermost part is held at approximately the same height, or where the rear flap is joined to the upper part of the rear flap, the height of the rear flap is adjusted to the rear flap. It can be made taller than the board. This rear insert plate can prevent a load stacked higher than the height of the rear flap from falling.

In addition, the rear flap is held by the rear flapping plate holding frame and attached to the rear flapping plate by the rear flapping plate holding frame provided on the rear flapping plate, and the rear flapping plate and the rear flapping plate device are provided integrally. Therefore, the rear flap device can be attached to or detached from the side flaps while the rear flap is attached. As a result, labor for separately attaching or detaching the rear tilting plate device and the rear inserting plate can be saved, so that the work processes for mounting and removing the rear tilting plate device and the rear inserting plate can be reduced.

At this time, since the rear flap attached to the rear flap device is not connected to the side flap attached to the side flap, the side flap can be connected without attaching or detaching the side flap. can independently attach and detach only the rear plate to and from the side flap. Any means or known means may be used for attaching the side insert plate to the side flap. The method described in can be adopted.

In addition, the rear flaps are attached to the rear flaps by the rear flaps mounting portions for detachably attaching the rear flaps to the rear ends of the rear flaps provided on both ends of the rear flaps in the width direction of the cargo bed. A device can be attached to the rear end of the side flap. At this time, since the lower part of the rear flap is not fixed to the cargo bed, when the rear flap device is attached to or removed from the luggage bed, it is only necessary to attach or detach the mounting portion for the rear flap, which is convenient. Yes, it can save you time.

When a swing restricting member is provided that contacts the bottom plate at a predetermined swing position to limit swinging of the rear flap, the swing limiting member further limits the movement of the swinging rear flap. can be done. That is, when the rear flap swings back and forth due to inertia as the vehicle moves forward and backward and the rear flap tilts, the swing restricting member hits the bottom plate and swings within a predetermined range. It is possible to stop the shaking of the rear flaps within a more appropriately restricted range, and to suppress the tilting of the rear flaps and the rear flaps held thereon beyond the limit. be able to. In addition, the term "hanging and swinging" described in the present invention means that the lower end of the rear flap is attached so that the upper end can swing in the front-rear direction, and the lower end draws an arc in one vertical plane by the action of gravity. It includes the meaning of rocking (vibrating).

In addition, if the rear flap device has a handle that is directly or indirectly provided on the rear flap and is provided in a direction that is parallel to the rear flap and is vertical when the rear flap is hung, the rear flap device can be attached to and detached from the cargo bed. When doing so, the work can be easily performed by gripping the handle.

Further, when the rear flap is made of punching metal, expanded metal, or art metal, the required and sufficient strength of the rear flap can be obtained and the weight can be reduced, so that the rear flap can be easily formed. It can be attached to and detached from the cargo bed.

In addition, in the case where the side flaps are provided with engaging portions for temporarily placing the rear flaps by detachably attaching them to the rear flaps after they are removed from the rear end of the side flaps, the rear flaps device may be attached to the side flaps. It can be removed from the rear end and installed along the side flaps.

Further, in order to solve the above-described problems, the truck bed structure of the present invention includes a bed having side flaps on both sides in the width direction, and a rear panel having a predetermined height and capable of substantially closing the rear opening of the bed. a gate plate, a rear gate plate holding frame provided on the rear gate plate and capable of holding the rear gate plate formed higher than the gate plate, and a rear gate plate provided at both ends of the rear gate plate, the side gate plates a rear flap device having a rear flap plate mounting portion for detachably attaching the rear flap plate to the rear end portion of the frame.

It is an example of a rear flap mounting portion that can be attached to the rear flap holding frames 11, 11 provided and capable of holding the rear flap 4a, and attachment receiving portions 20, 20 of the side flaps 2, 2, which will be described later. A certain mounting bar 13, 13, extending forward from the tip side of the mounting bar 13, 13, and when removing the rear tilting plate device 1 from the rear part of the cargo bed N and replacing it with the side tilting part 2, the upper surface of the side tilting part 2 Engagement portions 14, 14 that can be engaged with 21, stop plates 15, 15 and stop plates 15, 15, which are examples of rocking restricting members attached in contact with the lower side of the rear flap 10 so as to be substantially perpendicular to each other. It consists of handles 16, 16 erected substantially vertically upward from the rear end. The stop plates 15, 15 are attached to the mounting receiving portions 20, 20 of the side flaps 2, 2 and hang down (that is, in a substantially vertical position). 3 are mounted separately.

The rear flap 10 has a substantially rectangular frame portion 10a elongated in the left-right direction, and is composed of vertically mounted support pipes 100, 100, and a substantially horizontally mounted lower side pipe 101 and upper side pipe 102. and a net portion 10b provided in a region surrounded by and formed using an expanded metal.

Further, the rear flap plate holding frames 11, 11 are integrated with the rear flap plate 10 on the left and right end sides of the front side surface 103 of the rear flap plate 10, which is the front side when the rear flap device 1 is attached to the cargo bed N. installed in the The rear inserting plate holding frame 11 is formed in a substantially U-shape in plan view, in which two metal holding plates 110, 110 are spaced apart by a width that allows the rear inserting plate 4a to be inserted. ing. An opening 111 is formed on the opening side of the holding plates 110 , 110 .

The two openings 111 of the rear inserting plate holding frame 11 are a side end opening 111 a provided over the entire length of the rear inserting plate holding frame 11 in the longitudinal direction, and a side end opening 111 a provided over the entire length of the opening 111 in the width direction. It is provided continuously with the upper end opening 111b, and is generally formed in an upside-down "L" shape as a whole. A closed other end portion 111c is provided on the side opposite to the side end opening portion 111a, and a closed lower end portion 111d is provided on the opposite side of the upper end opening portion 111b.

In addition, the two rear inserting plate holding frames 11, 11 are arranged so that the side end openings 111a, 111a face each other and the upper end openings 111b, 111b are positioned at the upper end when in use. It is attached to the front side 103 of the plate 10 .

As a result, by inserting the rear inserting plate 4a into the rear inserting plate holding frames 11, 11 through the openings 111, 111, the ends of the rear inserting plate 4a in the width direction come into contact with the other end closed portions 111c, 111c from the inside. The rear inserting plate 4a can be accommodated in the rear inserting plate holding frames 11, 11 because the longitudinal ends of the rear inserting plate 4a abut against the lower end closing portions 111d, 111d from the inside.

The side plates 4b, 4b attached to the side flaps 2, 2 by arbitrary means and the rear plate 4a are attached without interfering with each other. There is no effect such as loose attachment of the insert plates 4b, 4b to the side flaps 2, 2.

Further, when removing the rear flap device 1 from the bed N, the rear flap device 1 can be removed from the bed N while the rear flap 4a is inserted into the rear flap holding frames 11, 11.例文帳に追加That is, since the trailing plate 4a is in contact with the other end closing portions 111c, 111c and the lower end closing portions 111d, 111d, the trailing plate 4a does not separate from the trailing plate holding frames 11, 11. Note that the number of the rear inserting plate is not necessarily limited to one, and it is also conceivable to attach two rear inserting plates, one to each of the rear inserting plate holding frames 11 and 11 .

The mounting bars 13, 13 are bar-shaped, and are bent substantially at right angles from the upper ends of the support pipes 100, 100 provided at both longitudinal ends of the rear flap 10, and extend in a direction substantially parallel to the rear flap 10. ing. Further, by fitting the root sides of the mounting bars 13, 13 to attachment receiving portions 20, 20 provided on the side flapping portions 2, 2, which will be described later, the rear flapping plate device 1 can be attached to the side flapping portions 2, 2. It can be attached to the rear part so that it can swing back and forth.

The engaging portions 14, 14 are attached to the front end sides of the mounting bars 13, 13 in the longitudinal direction, and the mounting plates 140, 140 extending from the mounting bars 13, 13 and the front end portions of the mounting plates 140, 140 are mounted. It consists of hanging plates 141, 141 which are vertically installed from the bottom.

As shown in FIG. 5(b), the engaging portion 14 is such that when the rear tilting plate device 1 is removed from the loading platform N and replaced with the side tilting plate 2, the mounting plate 140 is placed on the upper surface 21 of the side tilting plate 2. By engaging the side flapping plate 2 with the mounting plate 140 and the hanging plate 141 , the rear flapping plate device 1 is attached to the side flapping plate 2 .

The stop plates 15, 15 are attached to the lower side pipe 101 of the rear flap 10 from below so that the rear flap 10 rocks back and forth while the truck T to which the rear flap 10 is attached is running. movement can be restrained. As a result, it is possible to prevent the load from falling onto the road due to the rear flap 10 being largely opened rearward during traveling. The detailed movement of the stop plates 15, 15 will be described later.

The handles 16, 16 extend substantially vertically upward from the rear end portions 151 of the stop plates 15, 15 on the rear side surface 104, which is the rear side when the rear flap 1 is attached to the loading platform N. . The handles 16, 16 are integrated with the stop plates 15, 15 to form a substantially "L" shape.

Further, as shown in FIG. 3, mounting receiving portions 20, 20 capable of holding the mounting bars 13, 13 and mounting receiving portions 20, 20 are mounted on the rear end portions 22, 22 of the side flaps 2, 2. Pedestals 23, 23 for placing are provided. The mounting receiving portions 20, 20 include mounting recesses 201, 201 cut into a substantially "U" shape, and slide discs 203, 203 for opening and closing openings 202, 202 of the mounting recesses 201, 201 by sliding. 203, 203 and slide bars 204, 204 for operating the movement of the slide boards 203, 203;

Further, when the mounting bars 13, 13 are inserted through the openings 202, 202 of the mounting receiving portions 20, 20 and the slide bars 204, 204 are pulled down, the slide discs 203, 203 housed in the housing portions 205, 205 are displaced from the slide bars. 204, 204 to close the openings 202, 202 of the mounting receivers 20, 20; As a result, the mounting bars 13, 13 of the rear flap device 1 are held by the mounting receiving portions 20, 20 of the side flaps 2, 2, and the rear flap device 1 hangs down from the mounting receiving portions 20, 20. It is fixed to the rear part of the loading platform N.

Further, since the rear flap device 1 of the present embodiment is held by the attachment receiving portions 20, 20 of the side flaps 2, 2, the lower part of the rear flap 10 is not fixed to the truck bed N. There is no fear of leaving the

Here, the movement of the rear flap 10 will be described.
The rear flap 10 is hung downward from the mounting bars 13, 13, the lower end of the rear flap 10 is not fixed to the loading platform N, and there is a gap between the bottom plate 3 of the loading platform N and the stop plates 15, 15. Since the gap is provided, the rear flap 10 is pivotally supported by the mounting bars 13, 13 so as to be able to swing.

Specifically, FIG. 4(a) shows the position (that is, swing position) of the rear flap 10 when the truck T moves forward, and FIG. 4(b) shows the position when the truck T is stationary. 4(c) shows the position (that is, vertical position) of the rear flap 10, and FIG. 4(c) shows the position (that is, swing position) of the rear flap 10 when the truck T moves backward.

For example, as shown in FIG. 4(b), when the rear flap 10 is vertically installed from the mounting bars 13, 13 (for example, when the vehicle is stationary), the stop plates 15, 15 are the bottom plates of the cargo bed N. 3 (that is, floating from the bottom plate 3). 4A to 4C, the right side is the front of the vehicle and the left side is the rear of the vehicle.

Further, as the truck T advances, the rear flap 10 moves to the position shown in FIG. 4(a), and the front end 150 of the stop plate 15 comes into contact with the bottom plate 3 of the loading platform N to temporarily hold it. At this time, the stop plate 15 is inclined forward, and the rear end portion 151 of the stop plate 15 is at a position away from the floor. Even if the rear flap 10 is further pushed rearward, the tip 150 of the stop plate 15 is in contact with the floor of the loading platform N, so that the rear flap 10 is prevented from moving further rearward. can stop.

Also, as shown in FIG. 4(b), from the state in which the rear flap 10 is vertically installed from the mounting bars 13, 13 (that is, the vehicle is stationary), the rearward movement of the truck T causes the 2, the rear end portion 151 of the stop plate 15 comes into contact with the bottom plate 3 of the loading platform N to be temporarily fixed. At this time, the stopping plate 15 is tilted backward, and the tip portion 150 of the stopping plate 15 is at a position away from the floor. Even if the rear flap 10 is further pushed forward, the rear flap 1 does not move further forward because the rear end 151 of the stopping plate 15 is in contact with the floor of the loading platform N. can stop As a result, although the lower end of the rear flap device 1 is not fixed to the bottom plate 3, it is possible to sufficiently prevent the load from falling. Furthermore, since the lower end portion of the rear flap device 1 is not fixed to the bottom plate 3, the mounting of the rear flap device 1 can be accomplished simply by attaching and detaching the mounting bars 13, 13 to the mounting receiving portions 20, 20 of the side flaps. It can be easily removed.

If the stop plate 15 has a structure in which the length in the front-rear direction can be changed, it is possible to adjust the degree of inclination of the rear flap 10 and the rear insert plate 4a. Specifically, if the length projected forward from the rear flapping plate 10 is shortened, the rear flapping plate 10 and the rear flapping plate 4a are greatly inclined. becomes smaller.

In addition, by changing the length of the swing restricting member in the front-rear direction, the swing width of the rear flap can be adjusted and the swing width of the rear flap can be predicted. By setting the swing width in advance, it is possible to reliably prevent the load from falling.

Further, since the front extension member 152 and the rear extension member 153 can be fixed at appropriate positions in the direction of entry and exit, as shown in FIG. Alternatively, the length of the stop plate 15 can be adjusted by pulling out the rear extension member 153 from the rear end 151 to a predetermined length. As a result, the degree of inclination of the rear tilting plate 10 and the rear inserting plate 4a can be appropriately set.

It is also conceivable that the stop plate 15 has a slidable structure so that the length of the stop plate 15 can be adjusted so that the length of the stop plate 15 can be freely changed. As a result, the length of the stop plate 15 can be easily changed, and the degree of inclination of the rear swing plate 10 and the rear insertion plate 4a can be appropriately adjusted.

Further, the rear flap 10 is attached by the mounting bars 13, 13 so as to be swingable in a predetermined range in the longitudinal direction. Since the inserting plate tilts forward, the upper part of the load is pushed forward by the rear inserting plate, thereby preventing the load from falling backward.

1, 4, 5, and 6, the procedure for attaching and detaching the rear flap device 1 of this embodiment will be described below.
The side plates 4b, 4b are attached to the side flaps 2, 2 by arbitrary means independently of the rear plate 4a, and are not affected by the attachment or detachment of the rear plate 4a.

As a result, the rear tilting plate device 1 can be easily attached to the rear part of the bed N of the truck T. As shown in FIG.

At this time, the mounting bars 13, 13 are held in the mounting recesses 201, 201, and the lower end of the rear flap 10 is not fixed to the loading platform. 13 and positioned substantially vertically, and mounted so as to be able to swing back and forth.

Stop plates 15, 15 attached to the lower end of the rear flap 10 are spaced apart from the bottom plate 3 of the loading platform N, as shown in FIG. 4(b). Here, when the truck T moves forward, the rear flap 10 swings rearward about the mounting bars 13, 13. As shown in FIG. At this time, the front ends 150, 150 of the stopping plates 15, 15 come into contact with the bottom plate 3 of the loading platform N, so that the swinging of the rear flap 10 can be stopped, and the rear flap 10 largely swings backward. Dropping of the load from the loading platform N can be suppressed.

When the truck T travels backward, the rear flap 10 swings forward about the mounting bars 13, 13. As shown in FIG. At this time, the rear ends 151, 151 of the stop plates 15, 15 come into contact with the bottom plate 3 of the loading platform N, thereby stopping the swinging of the rear flap 10, and the rear flap 10 swings forward greatly. to prevent contact with the load.

[Rear flap device removal step (ST4)]
The slide bars 204, 204 are pulled up to house the slide boards 203, 203 in the housing portions 205, 205.例文帳に追加As a result, the openings 202, 202 are opened, so that the mounting bars 13, 13 can be taken out from the receiving parts 20, 20, and the rear flap device 1 can be easily removed from the cargo bed N.

[Temporary placing step of rear flap device (ST5)]
After being removed from the loading platform N, the mounting plates 140 of the engaging portions 14 of the tilting plate device 1 are placed on the upper surface 21 of the side tilting plate 2 . At this time, the rear tilting plate 10 and the rear inserting plate 4a are positioned outside the loading platform of the side tilting plate 2, and the hanging plates 141, 141 of the engaging portions 14, 14 are positioned inside the loading platform of the side tilting plate 2.
