Description

The present invention relates to a rope that prevents cargo from falling over when it is being transported on a cart.

Conventionally, when transporting luggage on a cart, there is a risk that the loaded item may slip off due to unevenness or steps in the road, so various methods have been proposed to prevent this. These include a cart with a stopper and secured with a rope, a case on the bottom of the cart with a rope winding device that pulls out the rope when in use to secure the luggage, and a cart that uses a belt pulled out from a reel to secure the luggage.
The methods disclosed in Patent Documents 1, 2 and 3 have the effect of preventing loads from falling over when being transported on a cart.

JP 11-321656 A JP2000-52993A Patent Publication No. 2022-91069

In Patent Document 1, a stopper is provided on the cart and secured with a rope, but since the cargo on the cart cannot be fastened in a cross shape, the cargo is prone to falling over. Therefore, a cross structure that can be fastened in both the long and short directions of the top plate is desirable.

In Patent Document 2, a rope winding device is provided inside a case on the bottom of the platform of the cart, and the rope is pulled out when in use to fasten the load in the longitudinal direction of the top plate. In a second embodiment, a rope winding device is also provided on the side of the platform, so that the load can also be fastened in the transverse direction of the top plate.
Therefore, the structure disclosed in Patent Document 2 can be fastened in both the longitudinal and lateral directions of the tabletop.
However, the rope winding device is a device that is originally installed on the cart, and cannot be used on any cart. Therefore, a device that can be easily used without a specific device and does not cause the load to shift is desired.

Patent Document 3 uses a belt that is pulled out from a reel, and can be used with any trolley. It can also be used in either the longitudinal or transverse direction of the trolley top. However, two belts are required to fasten in a cross direction; one belt cannot fasten in a cross direction. In addition, the belt accessories, such as reels and cam buckles, have a complex structure. Therefore, a structure that can be fastened in a cross direction more simply and economically is desired.

The purpose of this invention is to provide a rope that prevents cargo from falling over when it is being transported on a cart, and that can be fastened crosswise to the top plate in both the long and short directions with a single rope, making it simple and economical.

In order to achieve the above object, the present invention provides a rope for preventing cargo from shifting on a trolley, which includes a cross member for fastening a load in a cross shape with the rope, the cross member having a cylindrical threading portion through which the rope passes, a first hook material, and a second hook material, the cylindrical threading portion having a first hole portion and a second hole portion, the first hook material having a rope threading portion through which the rope passes at the first hole portion and a hook portion for hanging on a fold on the side of the trolley top plate, and the second hook material having a rope threading portion through which the rope passes at the second hole portion and a hook portion for hanging on a fold on the side of the trolley top plate.

The rope has a holder at one end that is attached to the handle of the dolly, and a hook for the top plate at the other end that is hooked onto the front of the top plate of the dolly, and the holder is equipped with a rope winding section, an attachment section, a pressure plate, and a belt.

Therefore, when attaching the rope to the dolly, first, the holder at the end of the rope is attached to the handle of the dolly, and the rope is pulled out from the winding part of the holder. Next, the hook material for the top plate at the other end of the rope is hooked to the front turn of the dolly top plate. Next, the cross member is brought over the luggage. The cross member has a cylindrical threading part through which the rope is passed, and a first hook member and a second hook member. The first hook member and the second hook member are passed through the first hole portion and the second hole portion of the cylindrical threading part. The first hook member and the second hook member are pulled out in the short direction of the top plate from the cylindrical threading part, and the hook portion of one hook member is hooked to the turn of the side of the dolly top plate, and the hook portion of the other hook member is hooked to the turn of the side of the dolly top plate on the opposite side. Finally, the length is adjusted by pulling in the long direction of the top plate with the adjuster.
In this way, a single rope can be used to fasten the tabletop in a cross shape in both the longitudinal and transverse directions.

In Patent Document 1, the cargo cannot be fastened in a cross shape, which makes it easy for the cargo to collapse. However, in the present application, the first hook material and the second hook material are pulled out from the cylindrical through-hole in the short direction of the tabletop, so the structure allows the cargo to be fastened in a cross shape in the long and short directions of the tabletop.

The structure in Patent Document 2 allows the rope to be fastened in both the long and short directions of the top plate, but it can only be used on carts equipped with a rope winding device. However, the present application can be easily used with a rope and a few accessories, as long as the cart has a "return" on the top plate of the cart. The "return" is for hanging the hook part of the hook material on the top plate of the cart.

Patent document 3 requires two belts and the belt accessories, such as reels and cam buckles, are complicated and expensive, but the present application uses a single rope and a few accessories that can be fastened in a cross shape, making it an economical rope.

Next, the locking mechanism of the rope winding portion 106 of the holder 102 will be described in detail.
10 is a front view of the winding unit 106 when it is unlocked. The winding unit 106 includes a roller unit 113, a handle 111, and a lock unit 112. The roller unit 113 is for winding the rope, and the rope can be wound by rotating the handle 111 in conjunction with the roller unit 113.

11 is a front view of the winding unit 106 when it is locked. When the locking portion 112 is pushed in the winding unit main body direction 119A, it is locked and the roller unit 113 does not rotate. When it is unlocked, when the locking portion 112 is pulled out in the winding unit outer direction 119B, it is unlocked and the roller unit 113 becomes rotatable.
In this manner, the winding section 106 is provided with a locking mechanism by the lock section 112 and the roller section 113 .

12 is an enlarged perspective view of the locking portion 112 and the roller portion 113. The locking portion 112 has a pair of spring portions 114 at the center inside the locking portion. The spring portions 114 are made of resin and have a long stroke, so that they have spring-like elasticity.
The lock portion 112 has a first claw portion 115 at the tip of the spring portion 114, and has a second claw portion 116a and a third claw portion 116b at the center of the spring portion 114.
The roller part 113 has a first window 117 and a second window 118 in the direction toward the ceiling. The first window 117 is larger than the second window 118. Although not shown, the roller part 113 also has the first window 117 and the second window 118 on the lower side of the roller part in the front view of Fig. 14. Thus, the roller part 113 has a pair of first windows 117 and a pair of second windows 118 for engaging with the spring parts of the lock part 112.

Figure 13 is an enlarged perspective view of the locking portion 112. The locking portion 112 has a pair of spring portions 114 arranged symmetrically with respect to the imaginary center line L of the locking portion 112 at the inner center of the locking portion 112.

Figure 14 is an enlarged perspective view of the locking portion 112 and roller portion 113 when the winding portion 106 is unlocked. The first claw portion 115 at the tip of the spring portion 114 of the locking portion is at the tip of the first window portion 117 in the winding portion main body direction 119A. The second claw portion 116a and the third claw portion 116b are engaged at the tip of the first window portion 117 in the winding portion outward direction 119B so as not to move further outward.

Figure 15 is an enlarged perspective view of the locking portion 112 and roller portion 113 when the winding portion 106 is locked. When the locking portion 112 is pressed in the winding portion main body direction 119A, it is locked. By pressing, the first claw portion 115 at the tip of the spring portion 114 of the locking portion moves from the first window portion 117 to the second window portion 118 and engages. The second claw portion 116a and the third claw portion 116b engage at the tip of the first window portion 117 in the winding portion main body direction 119A.

As described above, the locking section 112 has a pair of spring sections 114, each of which has a first claw section 115 at its tip and a second claw section 116a and a third claw section 116b on either side of the center of the spring section 114. The roller section 113 also has a pair of first windows 117 and a pair of second windows 118 that engage with the spring sections 114. This allows the winding section 106 to be provided with a locking mechanism.

If the winding portion 106 is provided with a locking mechanism, this has the effect of preventing the rope from loosening during fastening.
Therefore, the winding portion has a handle, a roller portion and a locking portion, the locking portion has a pair of spring portions, each of which has a first claw portion at the tip and a second claw portion and a third claw portion at the center of each of the spring portions, and the roller portion has a pair of first window portions and a pair of second window portions for engaging with each of the spring portions, thereby making the winding portion a rope characterized by having a locking mechanism.

The material for the parts of the cargo-prevention rope of the present invention is preferably a resin such as polypropylene (PP), but is not limited to this.

The rope may be made of rubber, but from the standpoint of cost, cost and safety, a fiber rope is preferable. However, it is not limited to this.

Therefore, by adopting the cross member of the present invention, it is no longer necessary to secure the load on the trolley with two ropes as in the past, but can be secured with a single rope.

This invention can be widely used as a rope to prevent cargo from falling over when being transported on a cart.
