Description

  The present invention relates to a tilting auxiliary member attached to the periphery of a truck bed.

  In general, an enclosure called “aori” is provided on the periphery of a truck bed so that a load (load) does not fall. This “aori” is provided on the side surface in the longitudinal direction (traveling direction, front-rear direction) of the truck and the rear side in the lateral direction (left-right direction, lateral direction) so that it can be rotated. When carrying it in, carry out the work by ensuring that the "Aori" is opened and opened, and a space for loading is secured. Then, when the carry-in of the load is completed, the worker closes and fixes the “aori”.

  However, when the height of the load exceeds the height of the cage, the load may protrude beyond the cage or may drop due to vibration during transportation.

  In order to cope with such a problem, a technique is known in which a plywood board, a door board, or the like having a height exceeding the tilt is erected along the tilt. Also, a technique is known in which a veneer plate or the like is not simply erected, but is fixedly installed on a cargo bed or the like as a tilting auxiliary member (see, for example, Patent Documents 1 and 2).

  The tilt assisting member of Patent Document 1 is composed of a frame provided on the inner side surface of the tilt and an abutting portion provided on the outer side surface of the tilt and connected to the support column of the frame. Are fixedly installed by sandwiching them in the tilt (see FIGS. 1 and 7 of Patent Document 1). As a result, the height of the tilt can be substantially increased, and the tilt assisting member can be fixed to the track and the workability of the installation can be improved as compared with the case where the plywood or the like is simply erected. it can.

  Further, the tilt assisting member of Patent Document 2 is composed of a quadrilateral flexible member provided with a plurality of support posts, and is fixed by inserting these support posts into a cylindrical member provided on the inner surface of the tilt. It is installed (see FIG. 1 and FIG. 2 of Patent Document 2). Thereby, similarly to Patent Document 1, the height of the tilt can be substantially increased, the tilt assisting member can be fixed to the track, and the installation workability can be improved.

A load can be carried into the loading platform 13 using a gap between the rear tilt 12-3 and the state. Similarly, the operator can take out the load from the loading platform 13.

  That is, the operator can work without removing the side members 2-1 and 2-2 from the loading platform 13 when carrying the load to the loading platform 13 or taking it out from the loading platform 13. The work can be performed without removing the member 2-3 from the side members 2-1 and 2-2. This eliminates the need to remove the side members 2-1 and 2-2 and the rear member 2-3, thereby reducing the work load.

[Rear member 2-3]
Next, the rear member 2-3 attached to the side members 2-1 and 2-2 will be described in detail. FIG. 6 is a diagram illustrating an example of a state in which the rear member 2-3 is attached to the side members 2-1 and 2-2.

  The rear member 2-3 includes mounting members 24 having recesses at both ends of the longitudinal surface. As shown in FIG. 1, the support column 20-1 of the side member 2-1 includes a hook-shaped attachment member 22, and the frame body 25-1 of the side member 2-1 has a support column 20 on its inner side surface. A mounting member 23 having a flat slide portion is provided in the vicinity of the mounting member 22 of -1.

  The operator inserts the rear member 2-3 into the hook of the mounting member 22, and then slides the slide portion of the mounting member 23 toward the mounting member 24, and the convex portion at the tip of the slide portion is mounted on the mounting member. Insert into 24 recesses.

  Thus, the state shown in FIG. 6 is obtained, and the rear member 2-3 is attached and fixed to the side member 2-1 and the side member 2-2 (not shown).

  Therefore, the rear member 2-3 is fixed in contact with the inner side of the hook of the mounting member 22 and the inner surfaces of the frame bodies 25-1, 25-2. Integrate. That is, the tilting auxiliary member 1 including the side members 2-1 and 2-2 and the rear member 2-3 can be securely fixed and installed on the main body of the truck 10. Therefore, even when the truck 10 is shaken during traveling, the vibration of the tilting auxiliary member 1 with respect to the truck 10 main body can be suppressed. In particular, it is possible to suppress the lateral and vertical shaking of the rear member 2-3 with respect to the loading platform 13 and the side doors 12-1 and 12-2 (when the truck 10 is used as a reference, the lateral and vertical shaking). it can.

[Other mounting examples of side members 2-1 and 2-2]
Next, regarding the side members 2-1 and 2-2 attached to the cargo bed 13, another attachment example different from FIG. 4 will be described. FIG. 7 is a view showing another example of the state in which the side member 2-1 is attached to the loading platform 13. As shown in FIG. The same applies to the side member 2-2. Note that the side tilt 12-1 is omitted.

  Comparing the attached state of the side member 2-1 shown in FIG. 4 with the other attached state of the side member 2-1 shown in FIG. 7, both of them are stays on the hinges 14-1 and 14-3. The positions of 21-1, 21-2 are different.

  In the attached state shown in FIG. 4, the stay 21-1 is attached to the rear side of the track 10 with respect to the hinge 14-1, and the stay 21-2 is also attached to the rear side of the track 10 with respect to the hinge 14-3. It is attached.

  On the other hand, in the other attachment state shown in FIG. 7, the stay 21-1 is attached to the hinge 14-1 so as to be adjacent to the front side of the track 10, and the stay 21-2 is attached to the hinge 14. -3 to be adjacent to the rear side of the track 10.

  Thereby, since the stays 21-1, 21-2 are sandwiched between the hinge 14-1 and the hinge 14-3, even when the truck 10 travels and swings in the front-rear direction, The stays 21-1 and 21-2 do not move with respect to the loading platform 13. That is, it is possible to suppress the vibration in the front-rear direction of the side member 2-1 with respect to the loading platform 13 and the side tilt 12-1. The same applies to the side member 2-2.

  Therefore, even when the truck 10 is shaken during traveling, the vibration of the tilting auxiliary member 1 with respect to the truck 10 main body can be suppressed. In particular, the vibration in the front-rear direction of the tilt auxiliary member 1 can be reliably suppressed.

  As another modification of the attachment state shown in FIG. 7, the stay 21-1 is attached to the hinge 14-1 so as to be adjacent to the rear side of the track 10, and the stay 21-2 is attached to the hinge. You may make it attach so that it may adjoin to the front side of the truck 10 with respect to 14-3.

[Forms of Side Members 2-1 and 2-2 for Holding Cabin 11]
Next, the form of the side members 2-1 and 2-2 that sandwich the cabin 11 will be described. FIG. 8A is a side view showing a state in which the side member 2-1 is in contact with the concave portion of the cabin 11, and FIG. 8B is a cross-sectional view thereof. The same applies to the side member 2-2.

  As shown in FIGS. 8 (1) and 8 (2), the cabin 11 includes recesses 32 on both side edges on the rear side. The front end of the frame body 25-1 of the side member 2-1 (the front end on the cabin 11 side) is in contact with the surface of the recess 32.

  In this state, when the side lever 12-1 (not shown) is closed and fixed, the inner surface of the side blade 12-1 comes into contact with the side surfaces of the columns 20-1 and 20-2. Then, the pressing force from the side tilt 12-1 is applied to the recesses of the cabin 11 via the columns 20-1 and 20-2 and the front end surface of the frame body 25-1 (the surface in contact with the recess 32). 32 acts on the direction of “→” shown in FIG.

  Accordingly, the side members 2-1 and 2-2 sandwich the cabin 11. Therefore, even when the truck 10 is shaken during traveling, the vibration of the tilting auxiliary member 1 with respect to the truck 10 main body can be suppressed. In particular, vibrations in the left-right direction of the tilt auxiliary member 1 can be reliably suppressed.

[Another configuration example of the support 20-1]
Next, another configuration example of the support 20-1 will be described. Another configuration example of the support column 20-1 is an integration of the stay 21-1 and the main body of the support column 20-1. FIG. 9 is a diagram illustrating another configuration example of the support 20-1.

  The column 20-1 is a flat plate projection having a single corner that extends in a direction perpendicular to the longitudinal direction of the column 20-1 at the opposite end of the frame 25-1 (not shown) and is bent at a right angle. (First flat plate protrusion 43 and second flat plate protrusion 44) are formed.

  The first flat plate protrusion 43 extends in a direction perpendicular to the longitudinal direction of the support column 20-1, and the second flat plate protrusion 44 extends in a direction perpendicular to the first flat plate protrusion 43. .
