DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading aid used for loading a load on a container or the like. For example, the present invention relates to a loading aid interposed between a ceiling and a floor of a container. The present invention relates to a loading assisting device capable of preventing the load.

[0002]

2. Description of the Related Art Conventionally, when a load is loaded on a load carrier such as a truck equipped with a load carrier or a box-structured load carrier, an empty space may be generated between the load such as the container. Such empty space may cause the loaded luggage to collapse or collapse during transportation.Therefore, in the past, the height of the luggage was lowered to reduce the empty space, or the empty space was filled with airbags. This secures the stability of the luggage and prevents the collapse of the luggage and the luggage. Here, when using an airbag, it is inflated by supplying air with a compressor or the like,
It was necessary to fill the empty space.

[0003]

Since the size of the airbag can be adjusted according to the amount of air supplied by the compressor, the airbag can freely follow the size of the empty space generated between the luggage, Although it is excellent in that it has a high degree of work freedom and is easy to use, it has a problem that it is necessary to install a compressor and related equipment in a container yard to fill the airbag with air. In addition, a certain amount of time is required to fill the airbag with air, and there is a problem that much time is required for loading. Therefore, the present invention provides a loading aid that can be set in a short time and the use location is not limited, and the fall of the load and the collapse of the load can be reliably prevented.

[0004]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, a loading auxiliary tool main body (for example, the loading auxiliary tool main body 2 in the embodiment) is made of a first rod-shaped member (for example, The outer pipe 4) in the embodiment and the second rod-shaped member (for example, the inner pipe 5 in the embodiment) are provided so as to be extendable and contractible, and are pressed against the distal ends of the rod-shaped members constituting both ends of the loading auxiliary tool body. Plate (for example, pressing plates 3A, 3 in the embodiment)

I do.
With such a configuration, for example, a container (for example,
After loading the load (for example, the load N in the embodiment) on the container C in the embodiment, the loading assistance is carried out along the measuring wall of the load (for example, the side wall K in the embodiment) from the side of the empty space formed between the loads. When the device is set up between the ceiling of the container (e.g., the ceiling T in the embodiment) and the floor (e.g., the floor U in the embodiment) and operated in a direction in which the belt is wound up by the belt tightening machine, the loading is performed. The auxiliary tool main body is extended, and pressing plates provided at both ends of the auxiliary tool elastically contact the ceiling and the floor, and are set between the ceiling and the floor.

The bar-shaped member is provided with an engaging portion (for example, the engaging hole 53 in the embodiment) that can be locked to the pin at the retracted position of the one bar-shaped member. With such a configuration, when the first rod-shaped member and the second rod-shaped member are in the retracted state, the pin provided on one of them is elastically protruded and is engaged with the engaging portion of the other rod-shaped member. Lock and lock the loading aid in the retracted position. Also,
When the locking of the pin to the engaging portion is released, the lock between the first rod-shaped member and the second rod-shaped member is released, and the extension of the loading auxiliary tool body is allowed.

According to a third aspect of the present invention, the pressing plate supported so as to be able to be biased is supported so as to be able to advance and retreat in the longitudinal direction of the loading aid with respect to the corresponding rod-shaped member. An indication unit (for example, a thrust-up force detection window 31 in the embodiment) is provided. With this configuration, when the loading aid is extended by winding the belt with the belt tightening device, the amount by which the pressing plate is displaced with respect to the loading aid is confirmed by the indicator. It is possible to adjust while checking the compression load.

According to a fourth aspect of the present invention, there is provided a belt winding portion (for example, such that a base end of the one rod member is wound around a pressing plate of the other rod member to which the unwinding end of the belt is fixed). A belt hook (for example, the belt hook 29 in the embodiment) that locks the bent portion M in the embodiment is provided. With this configuration, the first rod-shaped member and the second rod-shaped member are moved in a direction in which the first rod-shaped member and the second rod-shaped member are retracted when the wrapped portion of the belt is locked to the belt hook and the belt is tightened by the belt tightening device. It is possible to do.

According to a fifth aspect of the present invention, a belt fastener (for example, the belt fastener MG in the embodiment) is provided at at least one position on the winding end of the belt of the belt tightening machine (for example, the extra belt 12a in the embodiment). Is attached. With this configuration, it is possible to wind a plurality of the stacking assisting tools with a belt and stop with the hook-and-loop fastener.

According to a sixth aspect of the present invention, the two pressing plates are at positions eccentric with respect to the main body of the loading aid,

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a use state of the loading aid of the first embodiment of the present invention. As shown in FIG. 1, a loading aid 1 according to an embodiment of the present invention is used, for example, when loading a load N on a container C or the like placed on a railway wagon or a truck bed. is there.
The container C is set so as to protrude from the floor U and the ceiling T of the container C, and is fixed along the side wall K of the load N. In some cases, as shown in FIG. 1, a plurality of loading aids 1 are set according to the size of the load N to prevent the load N from falling over and collapsing. Note that a holding plate P is interposed between the loading aid 1 and the load N to prevent the load N from being damaged.

As shown in FIGS. 2 and 3, the loading aid 1 includes a loading aid main body 2 and pressing plates 3A and 3B at both ends thereof. The loading aid main body 2 is configured to be expandable and contractable by an outer pipe 4, an inner pipe 5, and a load applying pipe 40, both of which are formed in a square hollow cross-sectional shape. Specifically, an inner pipe 5 shorter than the inner pipe 5 is inserted into one end of the long outer pipe 4 and a load applying pipe 40 is slidably inserted into the other end of the outer pipe 4. Not to be. It is also possible to use the outer pipe 4, the inner pipe 5, and the load applying pipe 40 having a round cross-sectional structure.
Since the direction of 3B changes, the above-mentioned rectangular hollow cross section structure is desirable. Pressing plates 3A and 3B, which will be described later, are provided at the distal ends of the inner pipe 5 and the load applying pipe 40, which constitute both ends of the loading aid main body 2. The pressing plate 3A contacts the lower side of the floor U or the like, and the pressing plate 3B contacts the upper side of the ceiling T or the like.

As shown in FIGS. 4 and 5, a frame 7 of a ratchet type belt tightening machine 6 is attached to one end of the outer pipe 4 by bolts 8. The ratchet-type belt tightening machine 6 has a structure similar to that shown in, for example, U.S. Pat. No. 4,185,360. The shaft of a winding handle 9 rotatably supported by the frame 7 is configured as a winding shaft 10.
The belt 12 wound around the winding shaft 10 is gradually wound by the ratchet mechanism 11 by reciprocatingly rotating the winding handle 9.

The operation will be described in detail with reference to FIG. 4. When the winding handle 9 is reciprocally rotated between X and Y as shown by arrows, the belt 12 is wound around the winding shaft 10, and during that time, the original The rewinding of the take-up shaft 10 is restricted by the lock member 13 biting into the gear 13A. Then, when the winding is completed, the winding handle 9 is brought down to the Y side. When loosening, the clutch member 14 is released from engagement with the gear 13A by grasping the clutch lever 14 linked to the lock member 13.

The winding shaft 10 of the winding handle 9
The belt 12 is wound up so as to wind one end of the outer pipe 4, and the unwinding end is fixed to the pin 15 at the base end of the inner pipe 5. Here, a nylon shoe 16 that slides on the outer surface of the inner pipe 5 is attached to an inner wall of one end of the outer pipe 4 with a screw 17 and a cast-in nut 18. Nylon shoe 19 slidingly in contact with nut 20 and cast-in bolt 2
It is fixed by 1. These two nylon shoes 1
6 and 19, the expansion and contraction operation by the outer pipe 4 and the inner pipe 5 is smoothly performed. Further, the two nylon shoes 16 and 19 also have a function of guiding the belt 12.

That is, as described above, the belt 12 is unwound so as to wind one end of the outer pipe 4 and the unwinding end is fixed to the pin 15 at the base end of the inner pipe 5. A portion arranged so as to wind the base ends of the outer pipe 4 and the inner pipe 5 through the nylon shoes 16 and 19, that is, an end of the nylon shoe 16 attached to the outer pipe 4 at one end of the outer pipe 4; The end of the nylon shoe 19 on the inner pipe 5 side on the base end side of the inner pipe 5,
Each of the round portions 22 is provided, and the belt 12 is routed so as to guide the round portions 22. Therefore, when the belt 12 is unwound and wound up, the round portion 22 of the nylon shoes 16 and 19 continuously slides on the nylon shoes 16 and 19 so that a smooth operation with little friction can be realized.

In this manner, the tip of the inner pipe 5 inserted into one end of the outer pipe 4 is
Is supported. As shown in FIGS. 6 to 9, a pad 23 made of rubber or the like is welded or vulcanized to the plate 24 in the pressing plate 3A, and the pad 23 has a non-slip uneven portion 25 formed on the pressing surface. . A hollow, rectangular bracket 26 inserted into the tip of the inner pipe 5 is fixed to the plate 24 by welding.

Here, since the bracket 26 is mounted at an eccentric position with respect to the plate 24, the plate 24, that is, the pressing plate 3A is at an eccentric position with respect to the loading auxiliary tool main body 2. Specifically, as shown in FIG. 2, the bracket 26 is mounted offset to the side opposite to the side where the belt tightening device 6 is mounted, and as a result, the side where the belt tightening device 6 is mounted. The edge of the plate 24 slightly protrudes from the outer wall of the outer pipe 4 (projection amount D). The projecting amount D is set to a dimension smaller than the plate pressure of the load protection pressing plate P set outside the outer pipe 4 when the load is loaded. The same applies to a pressing plate 3B described later.

The bracket 26 is rotatably supported on a side having a large turning radius (eccentricity) with a constant frictional force by a bolt 27 and a U-nut 28 inserted and fixed to the outer pipe 4, thereby pressing the pressing plate 3A. Is foldable along the longitudinal direction of the loading aid main body 2. Here, since the pressing plate 3A is mounted eccentrically, in the folded state, the protruding length in the longitudinal direction is minimized. The inner pipe 5 is notched on the side wall of the tip and on the side where the bracket 26 rotates, thereby allowing the bracket 26 to rotate. Further, the above-mentioned constant frictional force is mainly caused by the U nut 28, but other members may be used (the same applies to the bolt 27 and the U nut 28 described below).

Here, a belt hook 29 is attached to the plate 24 together with the bracket 26 described above. The belt hook 29 is a U-shaped member that is open on the lateral side, and has a rising portion 29A formed from the lower end. The bent portion M (shown in FIG. 4) of the belt 12 that is folded back at the round portion 22 of the nylon shoe 16 on the outer pipe 4 side is hooked on the belt hook 29 to fix the inner pipe 5. The belt hook 29 is used to lock the outer pipe 4 and the inner pipe 5 at the retracted position so that the outer pipe 4 and the inner pipe 5 do not extend in the extension direction when the loading aid 1 is not used. At this time, the rising portion 29A prevents the belt 12 from coming off the belt hook 29 in the lateral direction.

The belt hook 29 functions as a support for the pressing plate 3A when the pressing plate 3A is folded. Thereby, the seat when the pressing plate 3A is folded is improved.

On the other hand, the load applying pipe 40 slidably inserted into the other end of the outer pipe 4 has a structure shown in FIGS.
As shown in FIG. 2, a guide hole 30 is formed on the base end side along the sliding direction. The guide hole 30 guides a bolt 27 (with a U nut 28) provided through the side wall of the outer pipe 4, and the load applying pipe 4 in the outer pipe 4.
The movement of 0 is restricted within the range of the guide hole 30. Further, the guide hole 30 of the load applying pipe 40 is provided.
A bolt 27 (with a U-nut 28) penetrates the distal end, and a coil spring 33 is mounted between the bolt 27 and the bolt 27 of the outer pipe 4.

Therefore, when the load applying pipe 40 receives a force in the retracting direction, the bolt 27 of the outer pipe 4 moves relatively inside the guide hole 30 toward the tip end of the load applying pipe 40 to compress the coil spring 33. Therefore, the pressing plate 3B of the load applying pipe 40 is urged in the extending direction of the load applying pipe 40. Here, on the outer wall of the outer pipe 4, as shown in FIG. 10, a thrust force detection window 31 is formed near the position where the eye level of the worker is located. The push-up force detection window 31 is set at a position where the base end of the load applying pipe 40 can be confirmed at the very end of the push-up force detection window 31 when the coil spring 33 is attached (see FIG. 2). At a predetermined position of the window 31, an index portion 32 is formed which indicates an appropriate position slightly wider than the general portion.
The proper position can be easily confirmed by using the tape 34 together.

That is, the push-up force detection window 31 detects an overload when the load applying pipe 40 is compressed and contracted, and confirms whether the compressive load applied to the loading aid 1 is within an allowable value. It is provided as a guide to do so.
For example, it can be determined that the tightening limit load has been reached when the edge of the load applying pipe 40 coincides with an appropriate position of the pushing force detection window 31. The limit load is set to such a value that the loading aid 1 is not deformed or the ceiling T of the container C is not deformed, and is set to an appropriate load for preventing the movement of the load. The pushing force detection window 3
Since 1 is provided near the position where the eyes of the worker are located, the work while checking the pushing force becomes easy.

The pressing plate 3B is supported on the distal end side of the load applying pipe 40 via a bracket 35 as shown in FIG. More specifically, the pressing plate 3B is formed by welding or vulcanizing a rubber pad 23 having the same configuration as that of the above-described pressing plate 3A to the plate 24. One end of a bracket 35 is rotatably supported by a bolt 27 and a U nut 28 with a constant frictional force in the plane of the pressing plate 3B. That is, the pressing plate 3B is supported rotatably about a direction along the longitudinal direction of the stacking aid main body 2 as an axis. Incidentally, reference numeral 25 denotes an uneven portion.

That is, a reinforcing material is usually provided on the ceiling T of the container C for reinforcement, and depending on the size of the load, the pressing plate 3B may hit the reinforcing material in an unstable state. In that case, it is possible to dodge the reinforcing material of the ceiling T by turning the pressing plate 3B. At this time, since the bolt 27 and the U-nut 28 are held at the pivoted position by frictional force, the pressing plate 3B does not shift during transportation.
When there is a moderate resistance when performing the work of turning, the work is easy to perform.

At the other end of the bracket 35, an elongated hole 36 is formed along the longitudinal direction of the loading aid main body 2, and a bolt 27 (a U nut 28) penetrating the load applying pipe 40 into the elongated hole 36. ) Is inserted, so that the bracket 35 can rotate with respect to the load applying pipe 40 after being pulled. Therefore, the pressing plate 3B is supported by the bracket 35 so as to be foldable about the direction along the longitudinal direction of the stacking assisting tool main body 2 in the same manner as the pressing plate 3A.
In the normal state, the pressing plate 3 </ b> B is formed by the slot 36.
Since the rotation is restricted in the load application pipe 40, the rotation does not occur carelessly. On the other hand, when turning, it can be easily turned simply by pulling, so that there is a merit that a simple structure is sufficient to function.

Here, the bracket 35 (similarly to the bracket 26 described above) is provided with a round portion R at the outer end in the rotation direction to avoid interference during rotation. It should be noted that the load applying pipe 40 is notched on the side wall at the tip and on the side where the bracket 35 rotates, and that the bracket 26 is allowed to rotate.
Is the same as Nylon shoes 16 and 19, which are provided between the outer pipe 4 and the inner pipe 5 as described above, are attached between the load applying pipe 40 and the outer pipe 4, respectively.

In FIG. 4, reference numeral 12a denotes a surplus side belt, and the belt 12 is pulled in the tightening direction by pulling the surplus side belt 12a.
As shown in FIG. 2, a hook-and-loop fastener MG is attached to the surplus side belt 12a at the winding end side and at a position slightly spaced from the winding end side. A plurality (for example, two) of the loading aids 1 are bundled by the hook-and-loop fastener MG, and the extra belt 12a is hooked on the belt hook 29 and then wound around the loading aids 1, 1, so that storage and transportation can be easily performed. Can be united. Prior to the binding, the pressing plates 3A and 3B are folded and placed so as not to hinder the binding.

Next, the operation will be described. First, an operation procedure at the time of attachment to the container C will be described. The pressing plate 3A on the inner pipe 5 side is installed on the floor U of the container C. Next, the clutch lever 14 of the belt tightening machine 6
With the lock released, the winding handle 9 is rotated to lower to the lower X position to loosen it, and the bent portion M of the belt 12 is removed from the belt hook 29.

Then, in a state where the outer pipe 4 is pressed against the holding plate P, the outer pipe 4 is pushed up until the pressing plate 3B of the outer pipe 4 hits the ceiling T. At this time, when the reinforcing material of the ceiling T interferes with the pressing plate 3B, the pressing plate 3B can be rotated to release the pressing plate 3B and set in a stable state. Next, while pressing the entire stacking assisting tool 1 against the holding plate P, the excess belt 12a is gripped and pulled downward until it stops.

Then, the hoisting handle 9 of the belt tightening machine 6 is gripped by the clutch lever 14 and the hoisting handle 9 is raised to the upper Y position. Thereafter, the above-described reciprocating rotation operation (rotation operation between XY) is performed. Then, the belt 12 is tightened. This tightening operation is performed by the pushing force detection window 31.
The process is performed until it is confirmed that the edge of the load applying pipe 40 coincides with the index portion 32. Therefore, it is possible to prevent the ceiling T of the container C from being deformed by applying a further load and to prevent the loading aid 1 from being deformed, and conversely, to determine the appropriate load for surely stopping the movement of the luggage due to insufficient load. Both effects can be obtained. Then, after confirming that the loading auxiliary tool 1 is securely fixed between the ceiling T and the floor U of the container C, the winding handle 9 of the belt tightening machine 6 is set to the upper Y position, and the setting operation is completed. I do.

Therefore, no compressor or other related equipment is required in the container yard, and it is possible to easily and quickly prevent the load N from falling down and collapsing. Also,
The loading aid 1 abuts on the ceiling T and the floor U of the container C with a pad 23 made of rubber or the like, and can abut on the holding plate P because the outer pipe 4 has a square cross section. Therefore, the load N can be stably supported. In addition, even if vibration during transportation acts due to the elastic force of the coil spring 33, these vibrations can be elastically received by the coil spring 33, so that the vibration does not come off and the mounting reliability is improved. it can.

Next, an operation procedure for removing the loading aid 1 from the container C will be described. While holding the loading aid 1 with one hand and holding the clutch lever 14, the lifting handle 9 is lowered to the lower X position to release the lock. Then, the belt 12 is pulled down and loosened, and the outer pipe 4 is lowered until it stops below. At this time, the holding plate P is removed so as not to fall down. Next, the bent portion M of the belt 12 is hooked on the belt hook 29, and the remaining belt 12a is pulled down until it stops. Then, the tightening handle 9 is reciprocated between XY as described above to lightly tighten the belt 12, and finally the tightening handle 9 is set to the upper Y position, and the pressing plates 3A and 3B are rotated. And fold it to complete the removal work. As a result, the outer pipe 4, the inner pipe 5, and the load applying pipe 40 are locked to each other in a state where the total length is the shortest, and the width direction is narrowed by folding the pressing plates 3A and 3B, so that the occupied space can be minimized. . Therefore, the storage space can be saved because it is compact.

Therefore, according to this embodiment, the load N is easily fixed between the ceiling T and the floor U of the container C in a short time, and the load N is securely transported without falling or collapsing. can do. In this case, as compared with the conventional method using an airbag, it is advantageous in that no additional equipment or the like is required at the place where the baggage N is to be loaded. In addition, the elastic force of the coil spring 30 functions as a cushioning member that absorbs the vibration and vibration of the container C in the expansion and contraction direction.
There is no drop or displacement during transportation, and the load N can be supported reliably.

Further, when the loading aid 1 is set, the tightening load can be checked while checking the thrust force detection window 31. Therefore, the tightening load becomes excessive and the ceiling T of the container C is deformed, The tool 1 itself is not deformed. Since the pressing plates 3A and 3B can be easily folded during storage, the occupied space in the width direction is reduced, and the storage space can be saved. Further, since the pressing plate 3 is disposed eccentrically with respect to the loading auxiliary device main body 2, the pressing plate P for preventing the load N from being damaged can be easily disposed without being disturbed by the pressing plate 3. It is possible to prevent the package 1 from being directly in contact with the package N and being damaged. Further, by supporting the pressing plate 3B so as to be rotatable about the longitudinal direction of the loading auxiliary tool main body 2, if the ceiling T has a beam and the pressing plate 3B cannot be stably pressed as it is, the ceiling T It is possible to make contact with the ceiling T in a state where the pressing plate 3B is rotated so as to avoid the beam, so that it can be set in a stable posture according to the situation of the mounting position, and the mounting reliability can be improved. Increase.

Next, a second embodiment of the present invention will be described with reference to FIGS. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
In this embodiment, as shown in FIG. 15, a pin 51 which can be elastically protruded by a torsion spring 50 is provided inside an inner pipe 5, and this pin 51 is inserted into a hole 52 formed in a side wall 5a of the inner pipe 5. It is set at the corresponding position. Further, the hole 52 of the inner pipe 5 at the retracted position on the side wall 4a of the outer pipe 4,
That is, the engaging hole (engaging portion) 53 is provided at a position corresponding to the pin 51.
Are formed. The retracted position indicates a position at which the inner pipe 5 is almost entirely inserted into the outer pipe 4 as shown in FIG.

The pin 51 has a tip 51a formed in a hemispherical shape, and has a retaining portion 51b at its base.
1a has a length sufficient to protrude outside through the hole 52 of the inner pipe 5 and the engaging hole 53 of the outer pipe 4 aligned with the hole 52a. The torsion spring 50 has a bent one end 50 a having an inner pipe 5.
And the other end 50b is locked in a locking hole 51c formed in the center of the bottom of the retaining portion 51b of the pin 51. One end 50a and the other end 50b are separated from each other. Are set inside the inner pipe 5 in a state where both are brought close to each other so as to apply a biasing force.

Here, the engagement hole 53 is formed near the belt tightening device 6 so that an unlocking operation of the pin 51 described later can be performed while standing like the operation of the belt tightening device 6. Has become. In this embodiment, FIG.
As shown in FIG. 4, the belt hook 29 of the first embodiment is not provided on the plate 24 of the pressing plate 3A of the inner pipe 5.

Therefore, in this embodiment, when the loading aid 1 is attached to the container C, as shown in FIG. 14, the inner pipe 5 inserted into the outer pipe 4 is required to be installed. Looking down,
The pressing plate 3 </ b> A of the inner pipe 5 is rotated from the state shown in FIG. 14 toward the floor of the container C, and the pin 51 protruding from the engagement hole 53 of the outer pipe 4.
Is pushed in against the torsion spring 50, the tip of the pin 51 is disengaged from the engagement hole 53, so that the extension of the loading aid main body 2 is allowed, and the inner pipe 5 extends downward by its own weight (see FIG. 14). The pressing plate 3A (indicated by an arrow) is grounded. As a result, by pressing the pin 51 while standing like the belt tightening device 6, the inner pipe 5 is pressed.
Can be extended, so that the burden on the operator can be reduced.

On the other hand, when removing the loading aid 1 from the container C, after releasing the restraint of the inner pipe 5 by the belt 12 of the belt tightening machine 6, the operator holds the outer pipe 4 while standing and holds the lower pipe as it is. When pressed, the inner pipe 5 is relatively inserted into the outer pipe 4, and the tip of the pin 51, whose protrusion is restricted by the side wall 4 a of the outer pipe 4 at the position of the hole 52 of the inner pipe 5, contacts the side wall 4 a of the outer pipe 4. When the pin 51 reaches the position of the engagement hole 53, the pin 51 projects from the engagement hole 53 by the elastic force of the torsion spring 50. As a result, its position,
That is, in the retracted position, the movement of the inner pipe 5 in the extending direction with respect to the outer pipe 4 is restricted, and the loading auxiliary tool main body 2 is locked in the retracted posture. Therefore, the worker can easily perform the work of installing and removing the inner pipe 5 with one touch in a standing posture with a small load. As a result, there is no need to perform a troublesome work in a low posture such as hooking or removing the belt 12 from the belt hook 29 as in the first embodiment, and the work time can be shortened.

The present invention is not limited to the above embodiment. For example, the case where the loading aid 1 is interposed between the ceiling T and the floor U of the container C has been described. It can also be used between the side walls.

As described above, according to the first aspect of the present invention, after a load is loaded on a container, the load is assisted along the measuring wall of the load from the empty space side formed between the loads. When the device is set up between the ceiling and floor of the container and operated in the direction of winding the belt with the belt tightening machine, the main body of the loading aid is extended, and the pressing plates provided on both ends of the Since it is set in a state where it is elastically in contact with the floor, there is an effect that the baggage can be easily fixed in a short time. In this case, unlike the case where an airbag is used, it is advantageous in that no additional facilities or the like are required at the place where the load is loaded. Further, even if vibrations or impacts are applied during the transportation of the load, at least one of the pressing plates is elastically in contact with the load. There is an effect that can be done.

According to the second aspect of the present invention, when the first rod-shaped member and the second rod-shaped member are in a contracted state,
If the pin provided on either one of the pins elastically protrudes and is locked to the engaging portion of the other bar-shaped member, the loading auxiliary tool body is locked in the retracted position, and the locking of the pin to the engaging portion is released. Since the lock between the first rod-shaped member and the second rod-shaped member is released and the extension of the stacking aid body is allowed, the first rod-shaped member and the second rod-shaped member can be easily locked with one touch. This has the effect of reducing the burden on the operator.

According to the third aspect of the present invention, when the loading aid is extended by winding the belt with the belt tightening device, the amount by which the pressing plate is retracted with respect to the loading aid is determined by the amount of the supporting portion. By confirming with, the extension load can be detected, so that an excessive load can be prevented from acting on the ceiling or the floor, and particularly the ceiling with low rigidity can be prevented beforehand. There is an effect that it can be easily determined that the load is working.

According to the fourth aspect of the present invention, the first rod-shaped member and the second rod-shaped member can be fixed by engaging the belt entangled portion with the belt hook and tightening the belt with a belt tightening machine. Can be moved in the retracting direction, so that the loading auxiliary tool body can be retracted to prevent it from jumping out at the time of transport, and that both rod-shaped members can be made compact.

According to the fifth aspect of the present invention, a plurality of bundled loading aids can be wound by a belt and stopped by a hook-and-loop fastener, so that they can be easily bound during storage and transportation. is there.

According to the invention described in claim 6, since the pressing plate can be easily folded at the time of storage, the space occupied in the width direction is reduced, and the storage space can be saved. In addition, since the pressing plate does not become an obstacle and the plate material for baggage protection can be sandwiched between the side wall of the baggage and the main body of the baggage auxiliary device, the baggage assisting device and the baggage directly come into contact with each other and damage the baggage. This has the effect of preventing sticking. Further, by supporting at least one of the pressing plates so as to be rotatable about the longitudinal direction of the stacking aid main body as an axis, the pressing plate is brought into contact with the pressing plate so as to avoid an obstacle member existing at the contacting portion of the pressing plate. Since it is possible to perform setting, it can be set in a stable posture according to the situation of the mounting position, and there is an effect that the mounting reliability is high.

According to the seventh aspect of the present invention, since one of the rod-shaped members can be mounted inside the other while being slidable and rotation-restricted, the positional relationship between the two pressing plates can be determined. This makes it possible to smoothly expand and contract the loading assisting tool body in a state where it is kept constant, and has an effect that it can be made lightweight and strong.
