[Prior art]
2. Description of the Related Art Conventionally, when loading a load on a loading platform such as a cargo loading container or a truck having a box structure loading platform, an empty space may be generated between the luggage such as a container. Such an empty space may cause the loaded luggage to collapse or collapse during transportation. Conventionally, the height of the luggage is lowered to eliminate the empty space, or an air bag is packed in the empty space. This ensures the stability of the luggage and prevents the collapse of the luggage and the collapse of the luggage. Here, when an air bag is used, it is necessary to inflate by supplying air with a compressor or the like to fill an empty space.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing a usage state of the loading aid of the first embodiment of the present invention.
As shown in FIG. 1, the loading assisting tool 1 according to the 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 freight car or a truck bed. is there. The container C is set so as to stretch on the floor U and the ceiling T of the container C, and is fixed along the side wall K of the luggage 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 and collapse. A presser plate P is interposed between the load assisting tool 1 and the luggage N in order to prevent the luggage N from being damaged.
[0012]
As shown in FIGS. 2 and 3, the stacking assisting tool 1 includes a stacking assisting tool main body 2 and pressing plates 3 </ b> A and 3 </ b> B at both ends thereof. The loading assist tool body 2 is configured to be extendable and contractable by an outer pipe 4, an inner pipe 5, and a load applying pipe 40, both of which have a square hollow cross-sectional shape. Specifically, an inner pipe 5 shorter than the inner pipe 5 is inserted into one end portion of the long outer pipe 4 and a load applying pipe 40 is slidably inserted into the other end portion. It is supposed not to. Although it is possible to use the outer pipe 4, the inner pipe 5, and the load applying pipe 40 having a round cross-sectional structure, the directions of the pressing plates 3A and 3B are changed by rotating with each other. Is desirable.
Press plates 3A and 3B, which will be described later, are provided at the tips of the inner pipe 5 and the load applying pipe 40 that constitute both ends of the loading assisting tool body 2. The pressing plate 3A is in contact with the lower side of the floor U or the like, and the pressing plate 3B is in contact with the upper side of the ceiling T or the like.
[0013]
As shown in FIGS. 4 and 5, a frame 7 of a ratchet belt tightening machine 6 is attached to one end side of the outer pipe 4 with bolts 8. The ratchet type belt tightening machine 6 is similar to the structure shown in US Pat. No. 4,185,360, for example. The shaft of the winding handle 9 rotatably supported by the frame 7 is configured as a winding shaft 10, and is wound around the winding shaft 10 by the ratchet mechanism 11 by reciprocating the winding handle 9. The belt 12 is gradually wound up.
[0014]
Specifically, the operation will be described with reference to FIG. 4. As shown by the arrows, the belt 12 is wound around the take-up shaft 10 by reciprocatingly rotating the winding handle 9 between XY, and during that time, the belt 12 tries to return to the original state. The rewinding shaft 10 is restricted from being unwound when the lock member 13 is engaged with the gear 13A. When the winding is completed, the winding handle 9 is brought down to the Y side. When loosening, the clutch member 14 linked to the lock member 13 is gripped to release the engagement of the lock member 13 with the gear 13A.
[0015]
The belt 12 wound around the winding shaft 10 of the winding handle 9 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.
Here, a nylon shoe 16 slidably contacting the outer surface of the inner pipe 5 is attached to an inner wall of one end of the outer pipe 4 by a screw 17 and a cast-in nut 18. A nylon shoe 19 that is in sliding contact is fixed by a nut 20 and a cast-in bolt 21. The two nylon shoes 16 and 19 allow the outer pipe 4 and the inner pipe 5 to smoothly extend and contract. The two nylon shoes 16 and 19 also have a function of guiding the belt 12.
[0016]
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. , 19 so that the base ends of the outer pipe 4 and the inner pipe 5 are wound around, that is, the end portion on the one end side of the outer pipe 4 of the nylon shoe 16 attached to the outer pipe 4, and the inner pipe 5 Each of the rounded portions 22 is provided at the proximal end of the inner pipe 5 of the nylon shoe 19 on the side, and the belt 12 is routed so as to guide the rounded portion 22.
Accordingly, when the belt 12 is unwound and wound, the belt 12 is continuously slid on the nylon shoes 16 and 19 by the rounded portions 22 of the nylon shoes 16 and 19 to realize a smooth operation with little friction.
[0017]
In this way, the pressing plate 3 </ b> A is supported on the tip of the inner pipe 5 inserted on one end side of the outer pipe 4.
As shown in FIGS. 6 to 9, the pressing plate 3 </ b> A has a pad 23 made of rubber or the like welded or vulcanized and bonded to the plate 24, and the pad 23 has a non-slip uneven portion 25 formed on the pressing surface. . In addition, a hollow square bracket 26 to be inserted into the end of the inner pipe 5 is fixed to the plate 24 by welding.
[0018]
Here, since the bracket 26 is attached to a position that is eccentric with respect to the plate 24, the plate 24, that is, the pressing plate 3 </ b> A is eccentric with respect to the stacking auxiliary tool body 2. Specifically, as shown in FIG. 2, the bracket 26 is attached offset to the side opposite to the side on which the belt tightening machine 6 is attached. As a result, the side on which the belt tightening machine 6 is attached. On the opposite side, the edge of the plate 24 protrudes slightly from the outer wall of the outer pipe 4 (projection amount D). The protruding amount D is set to a size smaller than the plate pressure of the load protecting press plate P set on the outside of the outer pipe 4 when loading the load. This also applies to the pressing plate 3B described later.
[0019]
The bracket 26 is supported by a bolt 27 and a U nut 28 that are inserted and fixed to the outer pipe 4 so as to be pivotable to a side having a large rotational radius (eccentricity) with a constant frictional force. It can be folded along the longitudinal direction of the tool body 2. Here, since the pressing plate 3A is eccentrically attached, the protruding length in the longitudinal direction is kept to a minimum in the folded state. The inner pipe 5 is a side wall at the front end, and the side on which the bracket 26 rotates is cut out to allow the bracket 26 to rotate. The 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 below).
[0020]
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 having an open side, and has a rising portion 29A formed from the lower end. The inner pipe 5 is fixed by hooking the bent portion M (shown in FIG. 4) of the belt 12 folded back at the rounded portion 22 of the nylon shoe 16 on the outer pipe 4 side described above. The belt hook 29 is used to lock the outer pipe 4 and the inner pipe 5 in the retracted position so that the outer pipe 4 and the inner pipe 5 do not extend in the extension direction when the stacking 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.
[0021]
The belt hook 29 functions as a support portion for the pressing plate 3A when the pressing plate 3A is folded. Thereby, the sitting at the time of folding of the pressing plate 3A is improved.
[0022]
On the other hand, in the load applying pipe 40 slidably inserted into the other end of the outer pipe 4, a guide hole 30 is formed on the base end side along the sliding direction as shown in FIGS. . The guide hole 30 guides a bolt 27 (with a U nut 28) provided through the side wall of the outer pipe 4, and restricts the movement of the load applying pipe 40 within the outer pipe 4 within the range of the guide hole 30. .
Further, a bolt 27 (with a U nut 28) is passed through the load applying pipe 40 at the tip side from the guide hole 30, and a coil spring 33 is attached between the bolt 27 and the bolt 27 of the outer pipe 4. ing.
[0023]
Therefore, when the load applying pipe 40 receives a force in the retracting direction, the bolt 27 of the outer pipe 4 moves relatively in the guide hole 30 toward the distal end side of the load applying pipe 40 and compresses the coil spring 33. The pressing plate 3 </ b> B of the load applying pipe 40 is biased in the extending direction of the load applying pipe 40.
Here, on the outer wall of the outer pipe 4, a push-up force detection window 31 is formed in the vicinity where the eye level of the operator is located as shown in FIG. The push-up force detection window 31 is set at a position where the proximal end of the load applying pipe 40 can be confirmed at the end of the push-up force detection window 31 with the coil spring 33 attached (see FIG. 2). At a predetermined position of the window 31, an indicator portion 32 is formed that indicates an appropriate position that is slightly wider than the general portion. The proper position can be easily confirmed by using the tape 34 together.
[0024]
That is, the push-up force detection window 31 performs overload detection when the load applying pipe 40 is compressed and contracted. As a guideline for confirming whether or not the compressive load applied to the load assisting tool 1 is within an allowable value. Is provided. For example, it can be determined that the tightening limit load has been reached when the edge of the load applying pipe 40 matches the appropriate position of the push-up force detection window 31. This limit load is set to a value that does not deform the load assisting tool 1 or the ceiling T of the container C, and an appropriate load to prevent the load from moving. Since the push-up force detection window 31 is provided in the vicinity where the eye level of the operator is located, the work while checking the push-up force is facilitated.
[0025]
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.
Specifically, the pressing plate 3B is obtained by welding or vulcanizing and bonding a rubber pad 23 having the same configuration as that of the pressing plate 3A described above to the plate 24. Further, one end of the bracket 35 is supported by the bolt 27 and the U nut 28 so as to be rotatable with a constant frictional force in the plane of the pressing plate 3B. That is, the pressing plate 3 </ b> B is supported so as to be rotatable about the direction along the longitudinal direction of the stacking auxiliary tool body 2. Reference numeral 25 denotes an uneven portion.
[0026]
In other words, the ceiling T of the container C is usually provided with a reinforcing material for reinforcement, and depending on the size of the luggage, the pressing plate 3B may hit the reinforcing material in an unstable state. In that case, it becomes 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 rotated position with frictional force, there is no deviation during transportation, and an appropriate resistance is obtained when the operation of turning the pressing plate 3B is performed. Work is easy.
[0027]
Further, a long hole 36 is formed in the other end of the bracket 35 along the longitudinal direction of the stacking assisting tool main body 2, and a bolt 27 (with a U nut 28) that penetrates the load applying pipe 40 into the long hole 36. The bracket 35 can be rotated after being pulled with respect to the load applying pipe 40. Therefore, the pressing plate 3B is supported by the bracket 35 so that the pressing plate 3B can be folded about the direction along the longitudinal direction of the stacking assisting tool main body 2 as the pressing plate 3A. In the normal state, the pressing plate 3B is restricted from rotating in the load applying pipe 40 by the long hole 36, so that it does not rotate carelessly. On the contrary, when rotating, it can be easily rotated by simply pulling, so that there is a merit that it functions sufficiently with a simple structure.
[0028]
Here, the bracket 35 (same as the bracket 26 described above) is provided with a rounded portion R for avoiding interference at the time of rotation at the outer end in the rotation direction. The load applying pipe 40 is the same as the bracket 26 in that the side wall at the tip and the side on which the bracket 35 rotates is cut off to allow the bracket 26 to rotate.
Nylon shoes 16, 19 similar to those 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.
[0029]
Here, in FIG. 4, 12a indicates a surplus belt, and the belt 12 is pulled in the tightening direction by pulling the surplus belt 12a. Then, as shown in FIG. 2, a hook-and-loop fastener MG is sewn and attached to the surplus belt 12a at a winding end side and a position slightly spaced from the winding end side. By bundling a plurality of (for example, two) stacking aids 1 with the hook-and-loop fasteners MG and hooking the excess belt 12a on the belt hook 29 and then wrapping them around these stacking aids 1 and 1, it is easy to store and transport. Can be united. Prior to binding in this way, the pressing plates 3A and 3B are folded and placed so as not to interfere with binding.
[0030]
Next, the operation will be described.
First, the operation procedure when attaching 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, in a state where the clutch lever 14 of the belt tightening machine 6 is grasped and the lock is released, the winding handle 9 is loosened by rotating it so as to be lowered to the lower X position, and the belt 12 is bent from the belt hook 29. Remove part M.
[0031]
Then, in a state where the outer pipe 4 is pressed against the pressing plate P, the outer pipe 4 is pushed up until the pressing plate 3B on the outer pipe 4 side 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 set in a state where the pressing plate 3B is rotated to escape.
Next, the remainder belt 12a is gripped while pressing the entire stacking assisting tool 1 against the holding plate P, and is pulled downward until it stops.
[0032]
Then, the hoisting handle 9 of the belt tightening machine 6 is gripped by the clutch lever 14 to raise the hoisting handle 9 to the upper Y position, and then the above-described reciprocating rotation operation (rotating operation between XY) is performed. Tighten up. This tightening operation is performed until it is confirmed that the end edge of the load applying pipe 40 matches the indicator portion 32 of the push-up force detection window 31. Therefore, it is possible to prevent the ceiling T of the container C from being deformed by the load more than this, and the load assisting tool 1 from being deformed, and conversely, determine the appropriate load to surely stop the movement of the load due to insufficient load. Both effects can be obtained.
Then, after confirming that the loading aid 1 is securely fixed between the ceiling T and the floor U of the container C, the hoisting handle 9 of the belt tightening machine 6 is set to the upper Y position to complete the setting operation. To do.
[0033]
Accordingly, the container yard does not require a compressor or other related equipment, and the load N can be prevented from falling over and being collapsed easily in a short time. The loading aid 1 abuts against the ceiling T and the floor U of the container C with a pad 23 made of rubber or the like, and abuts against the pressing plate P because the outer pipe 4 has a square cross section. Therefore, the luggage N can be supported stably.
Further, even if vibrations during transportation act due to the elastic force of the coil springs 33, these vibrations can be elastically received by the coil springs 33, so that there is no detachment due to vibrations and the mounting reliability is improved. it can.
[0034]
Next, an operation procedure when removing the loading aid 1 from the container C will be described.
While holding the load assisting tool 1 with one hand and holding the clutch lever 14, the hoisting 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 downward. 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 excess side belt 12a is pulled down until it stops. Then, the tightening handle 9 is reciprocally rotated between XY as described above, the belt 12 is lightly tightened, finally the tightening handle 9 is set to the upper Y position, and the pressing plates 3A and 3B are rotated. Fold it up and finish the removal work.
Thereby, 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, since it becomes compact, storage space can be saved.
[0035]
Therefore, according to this embodiment, the luggage N can be easily fixed in a short time between the ceiling T and the floor U of the container C, and reliably transported without the luggage N falling over or collapsing. it can. In this case, it is advantageous in that an incidental facility or the like is not required at the place where the load N is loaded, compared to the conventional case using an air bag, and can be set in a short time and the working time can be shortened.
Further, since the elastic force of the coil spring 30 functions as a buffer member that absorbs the shaking and vibration of the container C in the expansion and contraction direction, the baggage N is securely supported without dropping or shifting during transportation. Can do.
[0036]
Further, when the loading aid 1 is set, the tightening load can be confirmed while checking the push-up force detection window hole 31, so that the tightening load becomes excessive and the ceiling T of the container C is deformed, or the loading aid 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 arranged eccentrically with respect to the stacking assisting tool body 2, the presser plate P for preventing the luggage N from being damaged can be easily disposed without being obstructed by the pressing plate 3, and the stacking assisting tool. It is possible to prevent the luggage N from being in direct contact with the luggage 1 and being damaged.
Furthermore, by supporting the pressing plate 3B so as to be rotatable about the longitudinal direction of the stacking assisting tool body 2 as an axis, the ceiling T can be used when there is a beam on the ceiling T and the pressing plate 3B cannot be stably pressed as it is. Since the pressing plate 3B can be brought into contact with the ceiling T in a state of being rotated so as to avoid the beam, it can be set in a stable posture according to the situation of the mounting position, and mounting reliability Will increase.
[0037]
Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment, and description is abbreviate | omitted.
In this embodiment, as shown in FIG. 15, a pin 51 that can be elastically projected by a torsion spring 50 is provided inside the inner pipe 5, and the pin 51 is inserted into a hole 52 formed in the side wall 5 a of the inner pipe 5. It is set at the corresponding position. Further, an engagement hole (engagement portion) 53 is formed on the side wall 4 a of the outer pipe 4 at a position corresponding to the hole 52 of the inner pipe 5 in the retracted position, that is, the pin 51. The retracted position indicates a position where the entire inner pipe 5 is inserted into the outer pipe 4 as shown in FIG.
[0038]
The pin 51 has a hemispherical tip 51a and is provided with a retaining portion 51b at the base. The tip 51a has a hole 52 of the inner pipe 5 and an engagement hole 53 of the outer pipe 4 aligned therewith. It is long enough to penetrate and project outside. The torsion spring 50 has one bent end 50 a locked in the mounting hole 5 b of the inner pipe 5, and the other end 50 b locked in a locking hole 51 c formed in the center of the bottom of the retaining portion 51 b of the pin 51. The one end 50a and the other end 50b are set inside the inner pipe 5 in a state where they are close to each other so that a biasing force is applied in a direction away from each other.
[0039]
Here, the engagement hole 53 is formed in the vicinity of the belt tightening machine 6 so that the unlocking operation of the pin 51 described later can be performed while standing in the same manner as the operation of the belt tightening machine 6. .
In this embodiment, as shown in FIG. 14, the belt hook 29 of the first embodiment is not provided on the plate 24 of the pressing plate 3 </ b> A of the inner pipe 5.
[0040]
Therefore, in this embodiment, when the loading aid 1 is attached to the container C, as shown in FIG. 14, in order to install the inner pipe 5 inserted in the outer pipe 4, the inner pipe 5 is directed downward. Then, the pressing plate 3A of the inner pipe 5 is rotated from the state shown in FIG. 14 toward the floor surface side of the container C, and the pin 51 protruding from the engagement hole 53 of the outer pipe 4 is opposed to the torsion spring 50. Then, the tip of the pin 51 is released from the engagement hole 53, so that the extension of the stacking assisting tool body 2 is allowed, and the inner pipe 5 extends downward by its own weight (indicated by an arrow in FIG. 14). Is grounded.
As a result, the inner pipe 5 can be extended by performing the pressing operation of the pin 51 while standing in the same manner as the belt tightening machine 6, so that the burden on the operator can be reduced.
[0041]
On the other hand, when removing the loading assisting tool 1 from the container C, after releasing the restraint of the inner pipe 5 by the belt 12 of the belt tightening machine 6, when the operator holds the outer pipe 4 while standing and presses it down, 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 is engaged with the side wall 4 a of the outer pipe 4. When reaching the position of the hole 53, the pin 51 protrudes from the engagement hole 53 by the elastic force of the torsion spring 50. As a result, at that position, that is, the retracted position, the inner pipe 5 is restricted from moving in the extending direction with respect to the outer pipe 4, and the stacking assisting tool body 2 is locked in the retracted posture.
Therefore, the operator can easily perform the installation work and the removal work of the inner pipe 5 with one touch in a standing posture with little burden.

【The invention's effect】
  As described above, according to the invention described in claim 1, after loading a load on the container, the loading assist tool is stood along the measurement wall of the load from the empty space formed between the loads, and the container When the belt is tightened by a belt tightener and operated in the direction of winding the belt, the load assisting tool body expands, and the pressure plates provided at both ends elastically move between the ceiling and the floor. Since the bag is set in contact with the baggage, there is an effect that the load can be easily fixed in a short time. In this case, it is advantageous in that an incidental facility or the like is not required at the place where the load is loaded unlike the case where an airbag is used. Even if vibrations or impacts are applied during the transportation of the load, at least one of the pressing plates is in elastic contact, so that the shock can be absorbed and the set state can be reliably maintained. There is an effect that can be done.In addition, since the pressing plate can be easily folded during storage, there is an effect that the occupied space in the width direction is reduced and the storage space can be saved. In addition, since the pressure plate does not get in the way and the load protection plate can be sandwiched between the side wall of the load and the load assisting device body, the load assisting device and the load are in direct contact with each other and the load is damaged. There is an effect that can prevent that. Further, by supporting at least one of the pressing plates so as to be rotatable about the longitudinal direction of the stacking assisting device body, the pressing plate is brought into contact with each other so as to avoid an obstructing member existing in the contacting portion of the pressing plate. Therefore, it can be set in a stable posture in accordance with the situation of the mounting position, and there is an effect that the mounting reliability is high.
[0044]
According to the second aspect of the present invention, when the first rod-shaped member and the second rod-shaped member are brought into the contracted state, the pin provided on one of them is elastically projected and the other rod-shaped member is engaged. The loading assist device main body is locked in the retracted posture by being locked to the joint portion, and if the locking of the pin to the engaging portion is released, the lock between the first rod-like member and the second rod-like member is released, Since the extension of the load assisting tool main body is allowed, the first bar-shaped member and the second bar-shaped member can be easily locked with one touch, and the burden on the operator can be reduced.
[0045]
According to the third aspect of the present invention, when the stacking assisting tool is extended by winding the belt with a belt tightener, the amount by which the pressing plate moves backward with respect to the stacking assisting tool is confirmed by the support portion. This makes it possible to detect an extension load, so that an excessive load can be prevented from acting on the ceiling and floor, and in particular, a ceiling with low rigidity can be prevented from being damaged. There is an effect that it can be easily determined.
[0046]
According to the fourth aspect of the present invention, the first rod-shaped member and the second rod-shaped member are degenerated by locking the belt winding portion to the belt hook and tightening the belt with a belt tightening machine. Since it is possible to move in the direction, it is possible to reduce the stacking assisting tool main body, prevent popping out during transportation, and make both rod-like members compact.
[0047]
According to the invention described in claim 5, since a plurality of bundled stacking aids can be wound with a belt and fastened with a hook-and-loop fastener, there is an effect that they can be easily bundled during storage and transportation.
[0049]
  Claim6According to the invention described in the above, since one of the rod-like members can be slidable inside the other and can be mounted in a state in which the rotation is restricted, the positional relationship between the two pressing plates can be kept constant. The loading assist tool main body can be smoothly expanded and contracted, and it is advantageous in that it can be light and strong.
