  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 to 4 show an example of an on-vehicle load device according to an embodiment of the present invention. In the present embodiment, a load device 1 including a heater, a cooling fan, a control device, etc. (not shown) is accommodated in a rectangular parallelepiped container 2, and the container 2 is configured to be able to be loaded on a loading platform 4 of a vehicle 3. . The container 2 is fixed to the cargo bed 4 via the fasteners 5 at the lower four corners.

  The container 2 has a size that can be loaded on a vehicle 3 that is a 20-t truck, for example, and is designed so that the entire weight accommodating the load device 1 is within a range that can be loaded on the vehicle 3. The load device 1 is arranged in the container 2 so that the center of gravity of the entire container 2 including the load device 1 comes to an appropriate position when the container 2 is loaded at a predetermined position on the loading platform 4. It is designed so that can be carried on the loading platform 4 in a stable state and can be transported without hindrance.

  In addition, an insertion port (not shown) is provided at an appropriate position on the lower side of the container 2 so that the container 2 can be lifted by a forklift.

  The fastening tool 5 is configured to position the container 2 at an appropriate position on the loading platform 4 as described above and to securely fix the container 2 at that position when the container 2 is loaded on the loading platform 4 of the container 2. In the case of the present embodiment, the fastening tool 5 is configured as a mechanism called a twist lock, and as shown in FIG. 2, a convex side component 6 arranged on the loading platform 4 side and a concave side component arranged on the container 2 side. 7. And the container 2 provided with the concave part 7 is fixed with respect to the loading platform 4 provided with the convex part 6 by fitting the convex part 6 and the concave part 7 together.

  As shown in an enlarged view in FIG. 3, the convex component 6 includes a pedestal 8 fixed on the loading platform 4, a locking portion 9 that is rotatably installed on the top surface of the pedestal 8, and the locking portion 9. And a rotating lever 10 for rotating the.

  The pedestal 8 is a member having a short columnar shape, and the bottom surface is fixed to the cargo bed 4 by means such as welding or fastening. For example, as shown in FIG. 3, the pedestal 8 has a substantially rectangular cross-sectional shape in which one side is longer than the other side in a plan view, and the longitudinal direction is installed in a direction along the vehicle body direction.

  The locking portion 9 is a substantially quadrangular pyramid-shaped member installed on the upper surface of the pedestal 8 as shown in FIG. 3, and the shape of the bottom surface is substantially the same as the shape of the upper surface of the pedestal 8 as shown in FIG. Match.

  As shown in FIG. 3, the rotary lever 10 includes a shaft portion 10 a that forms a rotation axis of the locking portion 9 along the vertical direction, and a handle portion 10 b that is bent from the shaft portion 10 a and extends radially outward. . The shaft portion 10a extends vertically from the lower surface of the locking portion 9 through the base 8, and a handle portion 10b is integrally formed at the lower end of the shaft portion 10a. The rotary lever 10 and the locking portion 9 operate in conjunction with each other. By operating the handle portion 10b, the locking portion 9 is moved in the horizontal direction as shown in FIGS. 3 (A) and 3 (B). It can be made to rotate. Here, FIG. 3A shows a case where the locking portion 9 is in the release position, and FIG. 3B shows a case where the locking portion 9 is in the locking position.

  In addition, the shape of the base 8 and the latching | locking part 9 is not limited to the example shown here. For example, the cross section of the base 8 and the bottom surface of the locking portion 9 may be configured in an oval shape, a rhombus shape, or the like. Further, the shape of the upper surface of the base 8 and the shape of the bottom surface of the locking portion 9 do not necessarily have to match. As will be described later, when the locking portion 9 is in the release position, the locking portion 9 and the pedestal 8 can be passed through and fitted into the insertion hole 11, and when the locking portion 9 is in the locking position, the pedestal It is only necessary that the insertion hole 11 fitted to 8 cannot pass through the locking portion 9.

  The concave part 7 is a hollow box-shaped member as shown in FIG. 2, and is disposed at a required position (here, four corners) on the lower surface of the container 2. An insertion hole 11 into which the convex side component 6 (see FIG. 3) is inserted is opened on the lower surface of the concave side component 7. The insertion hole 11 has a long hole shape that can be fitted to the pedestal 8 of the convex part 6 (see FIG. 3), and when the container 2 is loaded on the loading platform 4, the longitudinal direction is the vehicle body direction. It opens in the direction along. Then, as shown in FIG. 3 (A), when the longitudinal direction of the locking portion 9 is in the release position that coincides with the longitudinal direction of the pedestal 8, the direction of the container 2 is adjusted to the loading platform 4 and the loading platform 4. The locking portion 9 and the pedestal 8 are allowed to pass through the insertion hole 11 so that the pedestal 8 and the insertion hole 11 can be fitted.

  The shape of the insertion hole 11 is not limited to the example shown here. It is sufficient that the pedestal 8 and the locking portion 9 can be passed through and can be fitted to the pedestal 8. For example, the shape of the insertion hole 11 does not necessarily match the cross-sectional shape of the pedestal 8, and it is sufficient that the displacement of the concave part 7 with respect to the convex part 6 can be limited as described later. .

  When the locking portion 9 and the pedestal 8 are inserted into the insertion hole 11, the concave part 7 stops when the lower surface abuts against the upper surface of the cargo bed 4 as shown in FIG. 4A. The insertion hole 11 is fitted to the pedestal 8 at the height of the pedestal 8, and the locking portion 9 is in a state where it can be rotated in the space inside the concave part 7 without being restricted by the insertion hole 11. . From here, as shown in FIG. 4B, when the rotary lever 10 is rotated 90 ° along the horizontal direction, the locking portion 9 is rotated 90 ° on the base 8 in conjunction with this, and the locking position is reached. Move on. In this state, a part of the locking part 9 protrudes from the upper surface of the pedestal 8. Even if the concave part 7 is moved above the convex part 6, the insertion hole 11 remains in the locking part 9. Can not pass. Thus, the convex part 6 and the concave part 7 can be inserted and removed from each other via the insertion hole 11 when the locking part 9 is in the release position, and the locking part 9 is in the locking position. In such a case, they are configured so that they cannot be inserted and removed from each other.

  The rotating lever 10 of the convex side component 6 protrudes from the side surface of the vehicle 3 or the loading platform 4 in a state where the locking portion 9 is at the release position as shown in FIG. 3A, and is engaged as shown in FIG. If it is installed in the direction along the side surface of the vehicle 3 or the loading platform 4 in the state where the stop portion 9 is in the locking position, the locking portion 9 can be easily operated via the rotary lever 10 and the container 2 is loaded. When the vehicle 3 is driven, the handle portion 10b does not protrude from the side surface of the vehicle body, which is safe (see FIG. 1).

  Next, the operation of this embodiment will be described.

  When the container 2 is loaded on the loading platform 4, as described above, the locking portion 9 is rotated to the release position by operating the rotation lever 10 of the convex component 6 provided on the loading platform 4 (FIG. 3A). The container 2 containing the load device 1 is lowered from above with respect to the loading platform 4 by a forklift or the like (see FIGS. 1 and 2). Since the convex side parts 6 are installed at positions corresponding to the concave side parts 7 provided at the four corners of the container 2 at various locations on the loading platform 4, the container 2 is simply lowered with respect to the loading platform 4. ), Each concave-side component 7 is fitted to the convex-side component 6. When the concave part 7 is thus fitted to the convex part 6, the center of gravity of the container 2 is positioned at an appropriate position on the loading platform 4.

  Here, since the engaging part 9 of the convex part 6 has a substantially quadrangular pyramid shape that narrows upward, the horizontal position of each concave part 7 is relative to each convex part 6. Even if there is a slight deviation, the insertion hole 11 moves along the slope of the locking portion 9 as the container 2 descends, and the concave part 7 is fitted to the convex part 6 at the correct position. ing. Thus, according to the present embodiment, positioning of the container 2 with respect to the loading platform 4 is easy.

  When the container 2 is placed on the loading platform 4, the rotating lever 10 of each convex side component 6 is operated to rotate the locking portion 9 to the locking position as shown in FIG. This is all that is required for fixing the container 2 to the loading platform 4, and is very simple compared to the case where the container 2 is secured using a wire rope or the like.

  In this state, the load device 1 is transported by the vehicle 3. At this time, the convex part 6 on the loading platform 4 side and the concave part 7 on the container 2 side are fitted by the base 8 and the insertion hole 11. The movement in the horizontal direction is limited. Furthermore, since the movement in the vertical direction is also limited by the locking portion 9, there is no fear that the container 2 will be displaced or dropped due to vibration during transportation. Since the center of gravity of the container 2 does not move from a fixed position with respect to the loading platform 3, the load device 1 can be transported in a stable state.

  When unloading the container 2 from the loading platform 4, the rotation lever 10 of each convex side component 6 is operated to reverse the loading procedure described above, and the locking portion 9 is moved to the release position as shown in FIG. If the container 2 is lifted by a forklift or the like after being rotated, the fitting of the convex side component 6 and the concave side component 7 can be released.

  Thus, in this embodiment, the load device 1 is configured as an in-vehicle load device that can be loaded on the vehicle 3 so that the load device 1 can be easily transported by the vehicle 3. At this time, in this embodiment, by providing the above-described fastener 5, positioning during loading is facilitated, loading and unloading work is simplified, and the container 2 is securely fixed on the loading platform 4. I have to. That is, for example, if each part of the container 2 is secured to the loading platform 4 using a wire rope with a hook or the like, positioning at the time of loading is difficult and troublesome. There is also a concern. In the present embodiment, such a problem is solved by applying the above-described configuration.

  As described above, in the present embodiment, the load device 1 is loaded on the loading platform of the vehicle 3 and the load device 1 can be transported. Therefore, the load device 1 can be easily transported using the vehicle 3. it can.

  Further, in this embodiment, a columnar pedestal 8 that is fixed to the loading platform 4 side of the vehicle 3, and the upper surface of the pedestal 8 rotates horizontally between the release position and the locking position with respect to the pedestal 8. It is arranged at a required location on the lower surface of the container 2 housing the load device 1, the locking part 9 that can be attached, the convex part 6 provided with the rotation lever 10 for operating the rotation of the locking part 9, When the insertion part 11 which can be fitted with the base 8 is provided on the lower surface and the concave part 7 having a space in which the engaging part 9 rotates is provided, and the engaging part 9 is in the release position When the base 8 and the locking portion 9 can be fitted through the insertion hole 11 and the base 8 and the insertion hole 11 are fitted, the locking portion 9 is in the locking position. Is provided with a fastener 5 configured to prevent the locking portion 9 from passing through the insertion hole 11, so that when loading the load device 1 onto the vehicle 3 Work is simple, there is no possibility of positional deviation or falling off even during transportation.

  Further, in the present embodiment, the locking portion 9 has a shape that narrows upward, so that positioning can be easily performed during loading.

  Further, in this embodiment, the rotating lever 10 includes a shaft portion 10a that penetrates the base 8 from the lower surface of the locking portion 9 and extends in the vertical direction to form a rotation axis of the locking portion 9, and a diameter from the shaft portion 10a. A handle portion 10b extending outward in the direction of the vehicle. The handle portion 10b protrudes from the side surface of the vehicle 3 when the locking portion 9 is in the release position, and is formed on the side surface of the vehicle 3 when the locking portion 9 is in the locking position. Since it is comprised along, it is easy to operate the rotation lever 10, and when driving the vehicle 3 loaded with the container 2, it is safe.

  Therefore, according to the present embodiment, transportation of the load device can be simplified.

  Note that the in-vehicle load device of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
