Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to stacking and connecting a plurality of panels in a vertical direction to close an opening of a cargo bed of a vehicle and move the panels upward when the opening is opened. The present invention relates to an improvement of a panel shutter for a vehicle, which is laminated in a door plate shape and accommodated in a storage box.

[0002]

2. Description of the Related Art A shutter for opening and closing a metallic door is generally used as a shutter installed in an opening of a luggage carrier of a truck.

On the other hand, a panel shutter for a vehicle is known in which a large number of individually independent panels are vertically stacked and the openings are opened and closed by moving the panels along a guide rail. (JP-A-4-73
(See Japanese Patent No. 391)

Hereinafter, the known panel shutter for a vehicle will be described with reference to the drawings. With reference to FIGS. 11 and 12, a known panel shutter closes an opening 2 of a loading platform 1 of a vehicle, and includes a large number of panels 3 and a storage box 4 that accommodates the panels 3. Each panel 3
Is guided by a guide rail 5, and is moved vertically in the opening 2 and in the front-back direction in the storage box 4. The storage box 4 is arranged at the upper end of the opening 2, and the panels 3 are stacked and stored in the front-rear direction in a door plate shape.

The opening and closing of the opening 2 by the panel 3 is performed as follows. When the opening 2 is changed from the closed state to the open state, the chain 6 is driven by the motor 6.
Is driven, and the lowermost panel 3 is lifted by the chain 7. Then, the upper panel 3 is sequentially fed into the storage box 4 along the guide rails 5 and stored therein. The panels 3 in the housed state are in a state of being laminated in a door plate shape.

When the opening 2 is changed from the open state to the closed state, the chain 6 is driven in reverse by the motor 6. Then, the lowermost panel 3 descends along the guide rail 5, and the adjacent panels 3 descend sequentially along the guide rail 5 to close the opening 2. Closed panel 3
Are in a state of being butted against each other like a door plate.

In the above operation, the operation in which the panel 3 enters the storage box 4 and is laminated in the front-rear direction is as follows. Referring to FIG. 13, as shown in FIG.
When the upper panel 3 is at the entrance position of the storage box 4, the swinging member 8 of the lower panel 3 is in the horizontal direction, and the end portion is in contact with the storage guide 9. In this state,
When the lower panel 3 further rises, as shown in FIG. 13 (B), the swinging member 8 rotates, and the guide roller 10 of the upper panel 3 exceeds the bending point of the guide rail 5 and the upper panel 3 moves. 3 is inclined in the direction of being pushed into the storage box 4. As a result, the fitting of the upper and lower panels 3 is released, and the lower panel 3 is further raised as shown in FIG. 13 (C). Then, the swing member 8 of the lower panel 3
Touches the upper panel 3 to further push the upper panel 3 into the storage box 4, and the guide roller 10 moves along the guide rail 5 parallel to the storage box 4. Then, as shown in FIG. 13 (D), the swinging member 8 of the lower panel 3 rises while supporting the side surface of the upper panel 3, resulting in the state shown in FIG. 13 (A). While repeating this, the panels 3 are sequentially housed in the housing box 4. When the panel 3 sequentially descends from the storage box 4 and closes the opening 2, the storage guide 9 swings downward, so that the panel 3 descends without being disturbed by the swing member 8.

[0008]

By the way, the above-mentioned conventionally known panel shutter has the following problems.
First, FIG. 14A is a cross-sectional view showing the guide rail and the guide roller in the opening portion, and FIG. 14B is a cross-sectional view showing the guide rail and the guide roller in the storage portion. As can be seen from the drawing, in the conventionally known panel shutter, the guide roller 10 provided on the side surface of the panel 3 is a roller supported by the central axis, and is supported by the guide rail 5 only in the radial direction to roll. ing.

In such a conventionally known guide roller 9, when a force in the thrust direction is applied to the panel 3, the panel 3 is moved to the position S in the figure due to a manufacturing error and a mounting clearance.
As shown by, the guide rail 5 and the swinging member 8 or the guide rail 5 and the end portion of the panel 3 come in contact with each other while being displaced in the left-right direction. For this reason, there is a possibility that a large resistance is generated when the panel 3 moves up and down, and smooth movement of the panel 3 is hindered.

Next, in the conventionally known panel shutter, FIG.
As shown in FIG. 5, the chevron-shaped fitting protrusion 11 of the lower panel 3
The upper panel 3 and the fitting recess 12 that is bent in a V shape are fitted to each other. In order to prevent the fitted panels 3 from separating from each other, an engaging hook 13 is provided in the vicinity of the upper end of the chevron-shaped fitting projection 11 so as to extend in the lateral direction. Has a structure that engages with the bent piece 12A of the V-shaped fitting recess 12.

The engagement hook 13 is disengaged when the panel 3 is accommodated in the storage box, and is engaged only when the opening is closed. The operation will be described. When the panel 3 is sequentially sent out from the storage box 4 and descends, the fitting recess 12 of the upper panel 3 laterally approaches the fitting projection 11 of the lower panel 2, At that time, the engaging hook 13 engages with the bent piece of the V-shaped fitting recess 12.

When performing the engaging action as described above, H shown in FIG. 15 is the width of the engaging gap, and the bent piece 12A of the fitting recess 12 is placed in the engaging gap H at a good timing.
Must be inserted. However, the engagement error occurs due to manufacturing error of each component, rattling in mounting, and the like. For this reason, the upper and lower panels 3 may not be fitted to each other sufficiently, resulting in lack of waterproofness. Further, if the upper and lower panels 3 are not fitted to each other insufficiently, a gap may occur and the cargo loaded on the cargo bed may be stolen.

Next, in the above-mentioned conventional panel shutter, the panel 3 is not locked with the opening 2 closed, so that the panel shutter itself is opened due to vibration during driving of the vehicle or other external force, and the luggage carrier is opened. May lead to theft of luggage.

Further, in the above-mentioned conventionally known panel shutter, as shown in FIG. 16, a spring 14 for pushing out the panel 3 accommodated in the storage box 4 is arranged next to the storage box 4 in parallel with the storage direction of the panel 3. Have been installed. Since the function of the spring 14 is to send the panel 3 at the innermost end to the end of the storage box 4, if the number of panels 3 increases, the stroke of the spring 13 must be increased correspondingly. When the contraction length is taken into consideration, it becomes difficult for the spring 14 having the same length as the storage box 4 to make such a stroke. Therefore, in the conventional structure, the installation becomes difficult when the number of the panels 3 increases. Further, according to the conventional structure, it is impossible to adjust the spring force against the decrease in the spring force, and it is difficult to use it stably for a long period of time.

Therefore, an object of the present invention is to provide a panel shutter for a vehicle, in which the above-mentioned drawbacks of the conventionally known panel shutter are improved.

[0016]

For this reason, even if a force in the thrust direction as shown by S in the figure is applied to the panel 2, the thrust force can be supported, and the guide rail 22 is supported by the end member 3 of the panel 3.
5 (described in detail in FIG. 5), and the guide rail 22 does not contact the swinging member 23 provided at the end of the panel 3.

Therefore, according to the structure of the guide rail 22 and the guide roller 21 of the present invention, the smooth movement of the panel 3 is guaranteed.

FIG. 2 shows another embodiment of the guide rail and guide roller of the present invention. In this embodiment, the rolling surface 21a of the guide roller 21 has a concave arc-shaped cross section. As in the first embodiment, the guide rail 22 is made of two circular rods. The guide rail 22 faces the guide rail bracket 24 and is fixed by welding. The rolling surface 21a of the guide roller 21 rolls while abutting while being sandwiched between the guide rails 22.

The embodiment shown in FIG. 1 is preferably used as a guide rail installed in the opening of a cargo bed of a vehicle, and the embodiment shown in FIG. 2 is used as a guide rail installed in parallel with a storage box. It is preferably used.

The structure of the guide roller and the guide rail of the present invention is not limited to the above embodiment, but the rolling surface of the guide rail has a concave arcuate cross section and the rolling surface of the guide roller has a convex arcuate cross section. The good thing is clear from the point.

Next, a panel lock mechanism according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4. A bracket 25 is fixed to the end wall 4a of the storage box 4, and an electromagnetic lock device 26 is attached to the bracket 25. Further, a lock arm 45 having a rotating shaft 31 is attached to the bracket 25. Further, the lock arm 45 has an end 45a for preventing the lock arm 45 from being rotated in the unlocking direction when the panel is locked. The lock arm 45 has an opening at the upper end of the panel 3
Immediately after the closing of, the panel 3 is fixed while being pressed downward. For this reason, the panel 3 is not lifted by the vibration or the external force due to the traveling of the vehicle, and the opening is not opened.

Details of the structure of the lock mechanism are as follows. A lock receiving member 27 is fixed to the upper part of the panel 3 at the upper end. The lock arm 45 is provided on the lock receiving member 27.
Engaging protrusion 27a with which the engaging portion 28 provided in
Is provided. A rotation spring 29 is attached to the lock arm 45.
Is provided to rotate the lock arm 45. The rotation spring 29 is fixed to the fixed portion 30, and the rotation moment of the lock arm 45 by the rotation spring 29 is applied to the lock arm 45.
So that the action lines Ma and Mb of the rotation moment are in the opposite directions depending on the rotation position of the lock arm 45.
Is set to exceed. That is, the lock arm 4
When the panel 5 rotates in the locking direction of the panel 3, when the panel 5 shown in FIG.
When the line of action is located on the left side of the rotary shaft 31 as indicated by Ma in (A) and the lock arm 45 rotates in the unlocking direction of the panel 3, as indicated by Mb in FIG. 4 (A). The line of action is located on the right side of the rotary shaft 31. Therefore, the rotating spring 29 pushes in the lock direction when the lock arm 45 is in the lock position, and pushes in the lock release direction when the lock arm 45 is in the lock release position. The electromagnetic lock device 26 has a slide pin 26a that reciprocates in the R and L directions of FIG. 4B, and when the lock arm 45 reaches the lock position, the lock arm 45 rotates in the unlocking direction. In order to prevent this, the slide pin 26a of the electromagnetic lock device 26 is locked by the lock arm 45.

To explain its operation, the state before the lowering of the panel 3 at the upper end is the state of the broken line in the figure. Now, when the panel 3 at the upper end is lowered, the engagement protrusion 27a of the lock receiving member 27 comes into contact with the engagement portion 28 of the lock arm 45 and pushes down the lock arm 45 to rotate it in the locking direction.
Then, the line of action of the rotation spring 29 becomes Ma, and the lock arm 45 is biased in the locking direction by the rotation spring 29 to lock the panel 3. At this point, the openings are fully closed by the plurality of panels 3. After fully closed, the electromagnetic lock device 26 slides the slide pin 26a in the R direction.
Then, the slide pin 26a slides and approaches to the lower surface of the end portion 45a of the lock arm 45, and the lock arm 4
5 is prevented from rotating in the unlocking direction. At this point, the locking operation of the plurality of panels 3 is completed. Next, the operation of opening the opening will be described. Before the rise of the panel 3 is started, the electromagnetic lock 26 is operated by an appropriate means to slide the slide pin 26a of the electromagnetic lock 26 in the L direction. Then, the lock arm 45 becomes rotatable in the unlocking direction. Then, when the panel 3 starts to rise, the panel 3 at the upper end pushes up the lock arm 45 via the lock receiving member 27 and rotates it in the unlocking direction.
Then, the line of action of the rotation spring 29 becomes Mb, and the lock arm 45 is urged in the unlocking direction by the rotation spring 29, and the lock of the panel 3 is released.
