Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing a hanging bracket from falling off in a lashing belt.

[0002]

2. Description of the Related Art Conventionally, a special vehicle provided with a lift device or the like for carrying an electric wheelchair has been known.
FIG. 9 shows a state where the wheelchair C is suspended by such a vehicle. As shown in this figure, when the wheelchair C is suspended, the entire wheelchair C is
The belt 8 is tied up with a long belt, and is hooked on the hook 7 of the lift device 2 using a ring-shaped hanging metal fitting 31 loosely inserted in the middle of the belt 8. The hook 7 is attached to one end of the wire, and is wound or unreeled by a winding device mounted on the vehicle, so that the wheelchair C can be raised and lowered.

[0003] The conventional tying belt 8 has a buckle attached to one end thereof so that the wheelchair can be tightened to an arbitrary length. FIG. 10 shows the periphery of a hook 32 provided on the other end side of the lashing belt 8 and hooked on a buckle. Has been inserted.

[0004]

When the tying belt 8 is not used, the tying belt 8 is mounted on the vehicle in a state where the tying to the suspended load is released, that is, the hook 32 is not hooked on the buckle. For this reason, when vibration of the vehicle is transmitted to the suspension fittings 31, as described above, the suspension fittings 3
Since 1 is merely loosely inserted into the lashing belt 8, it may pass through the hook 32 and fall off relatively easily. As a countermeasure, simply use a hanging bracket 3
The ring shape of 1 may be made smaller, but in such a case, the hanging fitting cannot be loosely inserted into the securing belt 8 and attached.

[0005] The present invention has been devised in view of the above-mentioned conventional problems, and an object of the present invention is to provide a structure in which a hanging bracket does not easily fall off in a lashing belt.

[0006]

According to a first aspect of the present invention, there is provided a securing belt for loosely attaching a suspended load, which is loosely inserted from an end side of the securing belt for hanging the suspended load. In a ring-shaped hanging member that allows the whole to be hung, a loop-shaped restricting portion having flexibility for restricting the hanging member from dropping off from the fixing belt is provided at a terminal portion of the fixing belt. It is characterized by being sewn.

According to a second aspect of the present invention, in the first aspect, the regulating portion sews the terminal of the securing belt by bending the end of the securing belt in a loop and diagonally toward the hanging bracket. By doing so, an invitation groove for hooking the hanging metal fitting is held at a sewn portion between the loop-shaped bent portion and the lashing belt.

[0008]

According to the first aspect of the present invention, since the restricting portion is formed in a loop shape at the end portion of the lashing belt, the hanging metal does not catch on the loop portion of the restricting portion and easily falls off. In addition, since the restricting portion has flexibility, it can be easily passed through the restricting portion and attached to the tie-down belt when the hanging metal is passed through.

According to the second aspect of the present invention, since the restricting portion is formed by bending the terminal portion of the lashing belt toward the hanging metal fitting and forming a hooking groove, the hanging metal fitting is formed by the hanging metal fitting. Since it is guided into the invitation groove, the falling-out is more reliably prevented.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. First, a vehicle in which the securing belt of this embodiment is used will be described with reference to FIG. The cargo bed of the vehicle shown in FIG. 1 can be opened and closed by a back door 1, and a lift device 2 is mounted at one end of the opening. Since the lift device 2 has a known structure, the description thereof will be briefly omitted. However, the lift device 2 includes a column 4 erected from the carrier 3 so as to be rotatable around an axis, and an upper end of the column 4. And a suspension arm 5 pinned with a support arm 6 which is folded or erected between the two.
Thus, it is possible to extend while maintaining a predetermined angle. A hook 7 for suspending a suspended load is provided at the tip of the suspension arm 5. The hook 7 is attached to an end of a wire (not shown), and the wire is connected to both arms 5 and 6.
It is possible to take up and unwind a winding device (not shown) while being wound around a pulley provided in the middle of the vehicle, thereby lifting or hanging the suspended load tied up by the securing belt 8. It is possible.

Next, the lashing belt 8 will be described (see FIG. 1). The lashing belt 8 is formed in a long strip shape from a material having sufficient tensile strength and flexibility. Buckle 9 for tightening lashing belt 8
Is attached. As shown in FIGS. 2 to 4, the buckle 9 has a main body 9A formed by bending a metal plate into a U-shape in cross section, and a through hole for passing the securing belt 8 on the bottom surface. 10 is open. A locking plate 11 is fitted tightly on the bottom surface of the main body 9A in front of the through hole 10 (left side in FIG. 3). A plurality of saw teeth 11 are formed on the upper surface of the locking plate 11 along the width direction.
A is formed.

On the other hand, a locking pin 13 for hooking a hook 12 to be described later is provided between both side pieces 9B at one end of the main body 9A. On the opposite side of the main body 9A, a support shaft 14 is provided between both side pieces 9B, and a lock member 15 is rotatably mounted. Lock member 15
The release piece 16 extends toward the locking pin 13 and the side facing the locking plate 11 around the support shaft 14 has an arcuate surface and the sawtooth 11A extends along the circumferential direction.
A plurality of locking teeth 17 meshing with are formed. Also,
A torsion spring 18 is wound around the support shaft 14 of the lock member 15, and biases the lock member 15 counterclockwise as shown in FIG. 3 or 4, that is, in a direction in which the saw tooth 11A and the locking tooth 17 mesh. doing. Therefore, both teeth 11
When the securing belt 8 is interposed between A and 17, the securing belt 8 is fixed at this position. However, when the release piece 16 is pressed against the torsion spring 18 to rotate the lock member 15 clockwise, the engagement between the sawtooth 11A and the locking tooth 17 is released, and the securing belt 8 is released. You.

A hook 12 shown in FIG. 5 is attached to an end of the tie belt 8 opposite to the buckle 9. The hook 12 is formed of a metal plate, and has a slit 19 on one side thereof for passing the end of the securing belt 8. On the other side, a claw edge 20 which is folded back into a U-shape and can be hooked on the locking pin 13 is formed.

The end of the securing belt 8 passed through the slit 19 of the hook 12 is processed as follows (see FIG. 7). That is, the tying belt 8 is
After being guided upward from the lower side through the slit 19, it is pulled out in the folding direction. Under that, further, turn the tip downward while drawing a loop,
The three terminals are sewn together near the hook 12 while making the terminals three-layer aligned. By doing so, the portion turned into a loop (hereinafter, referred to as a regulating portion 21) becomes inward in the length direction of the securing belt 8, and
That is, it extends toward the hanging fitting 22 described below. Since the restricting portion 21 extends obliquely in this manner, an invitation groove 23 that expands toward the hanging metal member 22 is held between the restricting belt 8 and the hanging metal member 22, so that the hanging metal member 22 can be easily guided here. doing.

In this embodiment, since the processing is performed such that the terminal of the tying belt 8 is sunk into the middle, the restricting portion 21 has a habit such that the leading end thereof rises from the surface of the tying belt 8. Therefore, a property that the entrance of the invitation groove 23 is enlarged in advance is provided.

The hanging fitting 22 is formed by bending a metal wire into a trapezoidal frame shape and connecting the ends without gaps. The hanging bracket 22 includes the securing belt 8 and the hook 12
The width is sufficiently wider than the width of the buckle 12 so that it can be loosely inserted from the hook 12 and attached to the securing belt 8.

Next, the operation and effect of this embodiment configured as described above will be specifically described. When the electric wheelchair C is unloaded from the vehicle or loaded in reverse, the wheelchair C is tied up by the securing belt 8. In this case, while the lashing belt 8 is wound around the seat of the wheelchair C, for example, as shown in FIG. The claw edge 12 of the buckle 9 is hooked on the locking pin 13 of the buckle 9. Then, as shown in FIG.
Of the saw tooth 11A and the locking tooth 1
Release the engagement with the fixing belt 7
Pull out the terminal fully and tie up wheelchair C. After that, when the pressing of the release piece 16 is released, the locking member 15 is restored by the spring force of the torsion spring 18 and the locking teeth 17 and the locking teeth are engaged with the locking belt 8 being engaged. The tightened state of the belt 8 is maintained.

Thus, the securing belt 8 for the wheelchair C
Is completed, the hanging metal fitting 22 is shifted to an appropriate position and hooked on the hook of the lift device. Then, if the winding or unwinding is performed by a winding device (not shown), the wheelchair C can be loaded on the carrier of the vehicle or conversely lowered.

When the tie-down belt 8 is not used, it is freely placed on the carrier. At that time, when the vehicle is subjected to vibration, the hanging fitting 22 is relatively freely shifted and moved to the end of the securing belt 8 because the hanging fitting 22 is loosely inserted into the securing belt 8. When the buckle 9 is moved to the buckle 9 side, the hanging fitting 22 cannot move beyond the buckle 9, so that there is no risk of dropping out. However, since the hooking tool 12 side is a side through which the hanging metal fitting 22 is inserted, there is a concern about this. However, in the present embodiment, since the restricting portion 21 is protrudingly provided, the hooking portion is caught and the dropping is effectively controlled. Is done. In particular, since the guide groove is formed by the restricting portion 21, the hanging fitting 22 is guided into the guide groove, and the drop-off can be more reliably achieved. Therefore, according to the present embodiment, a situation in which the hanging metal fittings 22 are accidentally dropped during traveling is eliminated, so that the dropped hanging metal fittings 22 can be searched or used again when the securing belt 8 is used. You can save time and effort.

The method of forming the restricting portion 21 is not limited to this embodiment, but may be as shown in FIG. That is, in the present embodiment, the terminal is finally sunk into the lower part of the upper fold, and the processing is performed.

The present invention can be further modified in various ways, and the following modifications are also included in the technical scope of the present invention. In any of the embodiments, the restricting portion 21 is formed by turning the terminal of the securing belt 8, but only the restricting portion 21 formed separately may be sewn. The object of use of the securing belt 8 is not limited to the electric wheelchair C, but is a highly versatile one.
