The rack handle is slidably mounted along the longitudinal direction of the rack, and a latch provided with a groove for detachably holding the rack handle is fixed to the support frame, and the rack handle is attached to the latch. A spring is installed between the rack handle and the rack to bias it in the direction of engagement.

[Example] An example of this invention will be described with reference to the drawings. The cargo loading device 1 has a rack 2 formed of aluminum material in a substantially rectangular shape, whose central portion is rotatably supported on a support frame 5 shown in FIG. As shown in FIG. 1, the rack handle 3 is slidably mounted along the longitudinal direction of the rack 2, and the support frame 5 has a latch provided with a groove for detachably holding the rack handle 3. 7 (FIG. 8), and a spring 33 is installed between the rack handle 3 and the rack 2 to bias the rack handle 3 in the direction of engaging the latch 7.

As shown in FIGS. 2 to 4, the rack 2 has side panels 21, 21 having substantially parallel cross sections parallel to each other in the longitudinal direction, and upper flanges at both ends of the racks 21 having stopper frames 22 having a circular cross section. The racks 2 are joined together to form a substantially rectangular shape, and a rack sleeve 23 is installed in the center of the rack 2 between the lower flanges of the side panels 21, 21.
A center frame 25 having a rectangular cross section is disposed along the longitudinal center line, and its lower side is fixed to the rack sleeve 23 via a spacer 26, and the rack plate 24 is attached to the side panel 2 on its upper side.
The entire surface is stretched in the form of a rectangle between 1 and 21. The lower flange of the side panel 21 has an inverted triangular shape with the apex at the center, and an angle-shaped reinforcing member 27 is attached to the lower edge of the flange to increase cross-sectional rigidity. Reference numeral 28 in the figure is a handle guide with a cylindrical cross section on which a rack handle 3 (to be described later) is slidably attached along the longitudinal direction of the rack 2. and are fixed to inner corners on both sides formed on the lower surface of the rack plate 24.

As shown in FIG. 1, the rack handle 3 includes a handle body 31 which is made of a member having a circular cross section and has a grip portion that is approximately U-shaped, and a lock bar 32 that is orthogonal to the handle body 31 adjacent to the grip portion. The rack handle 3 has a spring 33 attached to the extension of the handle body 31 into which the handle guide 28 of the rack 2 is inserted. The lock bar 3 is prevented from coming off by the snap spring 35, and the biasing force of the spring 33
2 is brought into contact with the front end of the handle guide 28.

FIG. 6 shows a support frame 5 for rotatably supporting the aforementioned cargo loading device 1 at the center of the rack 2.
Upper beam 51, lower beam 52, outer frame 53, 53, middle pillar 54
As shown in FIG. 5, for example, as shown in FIG. , 5 to support the load loading device 1. As shown in FIG. 7, the rack sleeve 23 of the rack 2 is attached to the center column 54 of the support frame 5.
A necessary number of bearings 55 for supporting both ends of the shaft 6 inserted therein are provided at predetermined intervals according to the number of storage stages of the cargo loading device 1. In addition, the support frame 5
The required number of latches 7 shown in FIG. 8 are attached to the outer surface of the outer frame 53 on the lock side in the same manner as described above. The latch 7 is entirely formed by cutting an aluminum plate, and has concave grooves 71 and 7 that detachably hold the lock bar 32 of the rack handle 3.
2,73 are provided. In the figure, 74 is a weight reduction hole, and 75 is a latch attachment hole.

With the above configuration, in the load loading device 1 which is locked in a horizontal or inclined state between the support frames 5, 5, the rack handle 3 is used as a guide to move the support frame against the biasing force of the spring 33. When the lock side outer frame 53 of the lock handle 3 is pulled outward, the lock bar 32 of the rack handle 3
can be released from one of the notched grooves 71, 72, or 73 of the latch 7 to release the locked state. Next, by releasing the lock, the load loading device 1 can tilt the rack 2 to either the left or right in the longitudinal direction with the central part of the rack 2 as the center of rotation. By engaging the lock bar 32 in this position, the latch 2 is held in an inclined state so that the cargo can easily slide on the inclined surface, thereby facilitating the unloading operation.

[Other Embodiments] FIGS. 9 and 10 show a case in which a rack handle 4 is added to the load loading device 1 described above, and rack handles 3 are provided at both ends of the rack 2 on the lock side.
A luggage loading device 11 is shown in which a rack handle 4 is provided on the free side and both rack handles 3 and 4 are interlocked by an interlocking device 8. Although the load loading device 1 described above has the rack handle 3 only on one end side of the rack 2, the unloading direction may be on the side opposite to the lock operation side.

This embodiment has the advantage that the rack 2 can be tilted from either unloading side. Hereinafter, only the configuration that corresponds to the above-mentioned luggage loading device 1 will be explained.

First, on the lock side (left side in the drawing), the interlocking plates 81 are connected to both U-shaped ends of the handle body 31 of the rack handle 3, and the bolts 8 are attached to the bracket provided on the lower surface of the center frame 25 of the rack 2.
A control link 82 is rotatably mounted with 3 as the axis Y, and a control rod 85 is connected to one end of the control link 82 and the interlocking plate 81 via pins 84, 84. The control rod 85 and the control link 8
2 is fixed so as to rotate integrally with the pin 84, and the control rod 85 and interlocking plate 81 are fitted in such a way that they do not swing against the pin 84, and even when the rack handle 3 is pulled outward. No force is transmitted to the control rod 85, and the free side rack handle 4, which will be described later, remains stationary.

On the other hand, on the free side (right side in the drawing), set the length of the lock bar 32 to the rack handle 3 by 2.
A rack handle 4 is used instead of the lock bar 42 which has been shortened to approximately the full width of the rack handle 4, and the rack handle 4 is attached to the free side end of the rack 2 in a position symmetrical to the rack handle 3, and the interlocking plate 81 and the control link 82 are connected by a control rod 86 via a pin 84, respectively,
It constitutes an interlocking device 8 that interlocks the rack handle 3 and the rack handle 4. Then, the rack handle 4 on the free side is attached to the support frame 5 in the same manner as described above.
When pulled outward, the interlock device 8 can release the locked state on the lock side. That is, in FIGS. 9 and 10, when the rack handle 4 is pulled to the right in the drawings (outward of the support frame 5), the control rod 8 is pulled through the interlocking plate 81.
6 attempts to rotate the control link 82 counterclockwise about the bolt 83 as the axis Y. This rotational force causes the control link 8 to
The lock-side control rod 85 connected to the other side of the lock is actuated, and the lock-side interlocking plate 81 is pulled outward toward the lock via the pin 84 by the operation of the control rod 85. The rack handle 3 is pushed out of the support frame 5 along the handle guide 28 against the urging force of the spring 33, and both ends of the lock bar 32 of the rack handle 3 are inserted into the notch grooves 71, 72, or 73 of the latch 7. It is possible to release the lock state of rack 2 by separating from either of them.

As mentioned above, the rack handle 3 can be unlocked from either the lock side or the free side, and the rack 2 can be tilted in a desired direction. In the above embodiment, since the lock was provided only on one side of the rack 2, the dimensions of the engaging surface of the latch 7 need only be narrow enough to engage one rack 2, as shown in FIG. 1 or 11 in multiple rows on the support frame 5, the frame thickness of the support frame 5 can be reduced by alternating the lock side and the free side, and the rack chamber length ( For example, it has the advantage of being able to prevent the enlargement shown in FIG. 5c).

Figures 11 and 12 show the third part of the load loading device.
The embodiment shown in the figure is a baggage loading device 12, which is different from the baggage loading device 1 or 11 described above, in that an opening groove 25a is provided on the upper surface of the center frame 25 of the rack 2 along the entire length in the longitudinal direction. The extrusion device 9 shown in FIG.
This is incorporated into the hollow part of No. 5.

The extrusion device 9 has lower sliders 91 disposed on both sides of a return spring 92, and a pull wire 94 connected to the pull wire 94 via a bracket 93.
One end is fixed to the side surface of the lower slider 91, and the other end is inserted through the return spring 92 in opposite directions. This extrusion device 9 is assembled by integrally fixing a top slider 95 formed in a T-shape to the upper surface of a lower slider 91 housed in the hollow portion of the center frame 25. The extrusion device 9 is a lower slider 9
The upper slider 95 interferes with the stopper frame 22 connected to both ends of the rack 2, thereby preventing the rack 2 from being pushed out from within the center frame 25 by the biasing force of the return spring 92. .

With the above configuration, the lower sliders 91, 91 of the extrusion device 9 incorporated in the rack 2 pull the pull wire 94 disposed inside the return spring 92 in mutually opposite directions, thereby resisting the biasing force of the return spring 92. One lower slider 91 connected to the other end slides inside the hollow portion of the center frame 25 along the upper surface opening groove 25a, and the upper slider 95 can push out the cargo. When the pulled pull wire 94 is loosened, the lower slider 91 returns to its original position due to the biasing force of the return spring 92.
The top slider 95 comes into contact with the stopper frame 22 and stops.

According to this embodiment, it is possible to more easily slide on the inclined rack plate 24a, thereby further improving the efficiency of unloading the cargo at the back of the rack.

[Effects of the invention] The luggage loading device of this invention has a rack formed in a substantially rectangular shape, whose center portion is rotatably supported on a support frame, and at least one longitudinal end of the rack has:
The rack handle is slidably mounted along the longitudinal direction of the rack, and a latch provided with a groove for detachably holding the rack handle is fixed to the support frame, and the rack handle is attached to the latch. A spring is installed between the rack handle and the rack, which biases the rack in the direction of engagement.The rack can be tilted by raising or lowering either end of the rack. This makes it easy to slip, and also allows for easy removal of cargo from the back of the rack. Furthermore, since the rack can be sloped on either side, unloading at the delivery destination can be carried out in any direction, which has an excellent effect of significantly improving delivery work.
