Belt hook temporary securing band

Abstract

To provide a belt hook temporary securing band that solves such a problem as when a worker is using a typical lashing belt 100 to perform strapping work alone, the belt hooks of the temporarily secured lashing belt attached to the truck's cargo hooks or cargo frame fall off due to their own weight.SOLUTION: The belt hook temporary securing band is passed through and mounted on multiple cargo hooks of the truck's bed, ensuring a certain level of tension and being pre-attached closely to the bed frame. A portion of the belt hook temporary securing band is partly and slightly raised from the bed frame to create an engagement space. In the engagement space, the J-shaped hook part of the belt hook (engagement fitting) at the end of a lashing belt placed on the cargo is engaged with the bed frame for temporary fixing. This makes it possible to prevent the belt hook (engagement fitting) from falling off without constantly pulling on the lashing belt.SELECTED DRAWING: Figure 3

Description

Technical Field

[0001] The present invention relates to a belt hook fixing band used to temporarily fix a belt hook of a securing belt temporarily fixed to a cargo bed hook or a cargo bed frame of a truck so that it does not fall off by its own weight when a worker performs a belt buckling operation alone on a load loaded on a vehicle such as a truck.

[0002] This belt hook fixing band is a belt-shaped band fixed to the lower surface of the cargo bed frame by a plurality of cargo bed hooks, and is a belt-shaped band having flexibility and elasticity to be closely attached to the cargo bed hooks with a certain tension. By sandwiching the belt hook of the securing belt between the mounted belt hook fixing band and the cargo bed frame to temporarily fix the belt hook, it is possible to prevent the belt hook from falling off by its own weight. As a result, the worker can easily perform the ratchet operation without continuously holding down the temporarily fixed belt hook on one side so that it does not fall off due to its own weight, engaging the belt hook on the other side, or continuously holding down the left and right belt hooks already engaged with the cargo bed hook. Such an efficient belt buckling operation is expected in the truck industry as a contribution to solving the so-called 2024 problem where the upper limit of the annual overtime working hours for automobile driving operations is limited to 960 hours. In this specification, the above-mentioned securing belt includes all securing means such as, for example, a lashing belt (cargo securing belt) having a flat cross-section, a fiber rope or a metal wire having a circular cross-section. The above-mentioned belt hook includes all engaging means such as a fitting for engaging the end of the lashing belt (J-type or S-type hook part or ring part), and a ring part (wacker part) at the end of the fiber rope or metal wire for hanging the ball.

Background Art

[0003] The following discloses a ratchet strap as an example of a securing belt, but the belt hook temporary fixing band according to the present invention is not intended to be limited to use with a ratchet strap. This ratchet strap is an example of a securing means widely used in the truck industry as a method for fixing a load on a truck bed. As shown in Fig. 7, a general ratchet strap 100 is composed of a fixed-side belt 101 and a winding-side belt (endless type) 102, and is configured to be able to secure a load via a ratchet 103. Belt hooks (ring portion and J-shaped hook) 101A and belt hooks (ring portion and J-shaped hook) 102A are provided at the ends of each belt.

[0004] In the operation of hanging the belt on the load with this general ratchet strap 100, after hanging the ring portion of the belt hook 102A of the winding-side belt (endless type) 102 on the bed hook provided at the lower part of the side edge of the bed frame, or after hanging the J-shaped hook on the bed frame, the winding-side belt 102 is passed over the load. Then, after similarly hanging the belt hook 101A of the fixed-side belt 101 on the opposite side on the bed hook or the bed frame, the end of the winding-side belt 102 passed over the load is passed through the ratchet and the ratchet is operated to perform the securing operation. In this case, as shown in Fig. 8, since the belt hooks 102A and 101A are likely to fall off the bed hook or the bed frame due to their own weight, there is the annoyance that the operator always has to pull and hold the winding-side belt 102 and the fixed-side belt 101 while operating the ratchet.

[0005] As a means of eliminating this nuisance, a wrap-around lashing belt (with magnet) 100A in which a magnet is attached to a belt as shown in Fig. 9 by the same applicant as the present application has been proposed (Patent Document 1). This is a configuration in which the belt hook is prevented from falling off by simply retrofitting this wrap-around rope fixing tool (with magnet) 100A to an existing general lashing belt. It has the merit of having a simple configuration and excellent on-site adaptability. However, since the lashing belt is fixed with a magnet against the draft on the side of the truck, depending on the model of the truck, if the draft on the side of the truck is made of aluminum or stainless steel, this wrap-around rope fixing tool (with magnet) has the drawback of not magnetically adhering to the draft. Furthermore, the wrap-around rope fixing tool (with magnet) must be attached to each of the existing general lashing belts, and there is a problem that the on-site adaptability is not always excellent.

[0006] As yet another conventional example, as shown in Fig. 10, a configuration is disclosed in which a magnet is pre-attached to the engaging fitting (ring portion) at the end of the lashing belt itself, and the engaging fitting (ring portion) is directly magnetically attached to the loading platform frame. In this configuration, since the ring portion of the engaging fitting is magnetically attached to the iron loading platform frame, it has the advantage of being able to prevent the belt hook from falling off due to its own weight. However, this configuration has the drawback that it cannot be applied to the lashing belt 100 without a magnet that is already widely used, on the premise that the magnet itself is pre-attached to the ring portion of the engaging fitting. Therefore, this configuration is not a configuration that can be applied to existing lashing belts that are already widely used, and thus has a serious drawback of being an extra expense for general truck drivers (operators).

Summary of the Invention

Problems to be Solved by the Invention

[0008] The problem to be solved is that when a worker uses a general lashing belt 100 alone to perform a belting operation on a load loaded on a vehicle such as a truck, there is no simple belt hook fixing tool for temporarily fixing the belt hook of the lashing belt temporarily fixed to the truck bed hook or the truck bed frame so that it does not fall off the truck bed hook or the truck bed frame due to its own weight.

Means for Solving the Problem

[0009] The present invention discloses a flexible and stretchable belt hook fixing band having a plurality of bed hook through holes along the central axis in the horizontal longitudinal direction of the belt body. By passing through and mounting the belt hook fixing band through the plurality of bed hooks provided at a plurality of locations downward at predetermined intervals at a plurality of locations on the truck bed frame in each of the bed hook through holes, the belt hook fixing band is preliminarily attached in close contact with the truck bed frame with a certain tension. In this specification, "in close contact with the truck bed frame" includes "in the vicinity of the truck bed frame", and includes a state of being disposed in the vicinity of the truck bed frame to such an extent that it does not fall off, and is not necessarily limited to a state of being in contact and disposed. Also, since the installation intervals of the bed hooks naturally differ for each truck, the plurality of bed hook through holes are provided on the band continuously or at regular intervals. That is, since the interval between the bed hook through holes through which the bed hooks are passed and mounted and the installation interval of the bed hooks do not necessarily exactly match and may have a slight deviation, a horizontal cut is provided in the bed hook through holes of the belt body, and the slight deviation between the interval of the bed hook through holes and the installation interval of the bed hooks is absorbed by this cut and the stretchability of the belt itself. Also, of course, this flexible belt body has a strength sufficient to hold the weight of the belt hook (such as an engaging metal fitting).

[0010] The method of using this belt hook temporary fixing band is to pass a plurality of cargo bed hooks of the truck through the through holes of each cargo bed hook, and attach the flexible and stretchable belt hook temporary fixing band to the cargo bed frame closely with a certain tension. When engaging the belt hook, the truck driver (operator) pinches a part of the belt hook temporary fixing band with his finger and slightly lifts it partially from the cargo bed frame to create an engaging space. In the lifted engaging space, engage the J-shaped or S-shaped hook part of the engaging fitting at the end of the lashing belt hung on the cargo to the cargo bed frame, or engage the ring part to the cargo bed hook. After that, if the finger is released from the part of the belt hook temporary fixing band pinched by the finger, the engaging fitting engaged to the cargo bed frame by the tension of the belt hook temporary fixing band itself is held by the belt hook temporary fixing band on the cargo bed frame and the cargo bed hook, preventing it from falling off.

[0011] By holding the engaging fitting pushed up from below to above by the belt hook temporary fixing band in this way, the truck driver (operator) can always prevent the belt hook (engaging fitting) from falling off without continuously pulling the lashing belt. Therefore, the truck driver (operator) has the advantage that he can perform a smooth ratchet operation without worrying about the belt hook already engaged to the cargo bed hook or the cargo bed frame falling off. Incidentally, the flexible belt body may be composed of an elastic body such as a rubber body or a stretchable fiber in order to securely hold the weight of the belt hook to be prevented from falling off closely to the cargo bed frame.

Effect of the Invention

[0012] Unlike the conventional racing belt described above, which has an externally attached "wrapping type rope temporary fastener (with magnet)" (see Fig. 9) or a configuration in which a magnet is pre-attached to the engaging fitting (ring part) itself (see Fig. 10), in the belt hook temporary fastening band according to the present invention, by inserting the loading platform hooks of each truck through the loading platform hook through-holes and pre-attaching this belt hook temporary fastening band to closely adhere to the loading platform frame, even when using an existing general racing belt, it is possible to surely prevent the problem that the belt hook (engaging fitting) falls off during the belt hanging operation. That is, the existing racing belt will not be wasted. In addition, this belt hook temporary fastening band is commercialized by making a long belt into a roll shape, and the truck driver can cut the belt to an appropriate length according to the length of the loading platform of each truck, so that the belt hook temporary fastening band of the present application can be inexpensively attached to the truck, which also has the advantage at the loading site.

Mode for Carrying Out the Invention

[0014] Fig. 1(A) is a plan view showing the outer shape of the belt hook temporary fixing band (1) according to the present invention, and (B) is a cross-sectional view taken along A-A. A lashing belt (fastening belt) with a flat cross-section, a fastening belt including a fiber rope or a metal wire with a circular cross-section, etc., a fitting for engagement (J-shaped or S-shaped hook part, ring part) attached to the end of the belt, or a ring part (wacker part) at the end of a fiber rope or a metal wire for hanging a ball, reliably prevents the problem of falling off from the truck bed hook or the truck bed frame during the operation of securing the loaded goods. This is achieved by the extremely simple belt hook temporary fixing band (1) according to the present invention. This belt hook temporary fixing band (1) is composed of a flexible and stretchable belt body (10) and through holes (20) for truck bed hooks arranged at regular intervals along the central axis in the horizontal longitudinal direction of the belt body. A truck driver (worker) attaches the flexible and stretchable belt hook temporary fixing band (1) according to the present invention in close contact with the lower surface of the truck bed frame in advance while applying a certain tension. The method of this attachment is to insert the truck bed hook through the through holes (20) for truck bed hooks at multiple locations while slightly pulling the flexible and stretchable belt body (10), and attach it as close as possible to the truck bed frame while applying a certain tension. And when engaging the J-shaped hook part, which is the tip part of the fitting for engagement of the lashing belt, with the truck bed frame, only a part of the belt hook temporary fixing band (1) near the J-shaped hook part is pinched with the finger and slightly lifted from the truck bed frame to form a small engagement space large enough to insert the J-shaped hook part. When lifting a part of the belt hook temporary fixing band, the stretchable belt hook temporary fixing band will shift slightly horizontally, but the shift can be absorbed by the stretchability of the belt body (10) and the notch of the horizontally long through hole (20) for truck bed hooks. After inserting the J-shaped hook part into this small engagement space and engaging it with the truck bed frame, when the finger is released from the belt hook temporary fixing band (1) with a certain tension, the falling off of the J-shaped hook part temporarily fixed by the tension of the belt hook temporary fixing band (1) itself is easily prevented. By this simple operation, it is realized that the truck driver (worker) can efficiently proceed with the securing work while the J-shaped hook part is temporarily fixed to the truck bed frame by the belt hook temporary fixing band.The specific configuration of this belt hook temporary fixing band will be described in detail below.

[0015] First, the belt body (10) that constitutes the belt hook temporary fixing band (1) is a strip-shaped band and has flexibility and elasticity. A plurality of loading hook through holes (20) are provided in the longitudinal direction at approximately the center in the short side direction of the belt body (10). The width of the belt hook temporary fixing band (1) in the short side direction is, for example, from 40 mm to 50 mm, and the longitudinal direction is the length between the frontmost hook and the rearmost hook of the truck. However, it is not intended to be limited to this size. Also, the belt hook temporary fixing band (1) may be any belt that has the strength to hold the length of the loading frame to which the engaging fitting of the lashing belt engages and the weight of the engaging fitting that engages with the loading frame. Specific numerical values of the length and strength are design matters rather than invention matters, so details will be omitted. Also, the cut size of the loading hook through hole (20) corresponds to the thickness of a general loading hook and is sized to engage with the loading hook and hold the weight of the engaging fitting. However, as with the above, specific sizes are design matters and will be omitted.

[0016] Of course, the mounting intervals of the loading hooks of the truck vary slightly depending on the model. Therefore, in the longitudinal direction of the belt of the loading hook through hole (20), there are horizontal cuts in the longitudinal direction, and there are also variations in the protruding distance of the loading hook from the loading frame, so vertical cuts are provided. It is fully possible to absorb the variations in the hook mounting positions for each truck model by these cuts. Specific numerical values of the cuts are also design matters and will be omitted. Regarding the material of the belt body (10), there is no particular limitation as long as it has flexibility and elasticity. Of course, it may be composed of an elastic body such as a rubber body or stretchable chemical fiber. Since these are all existing materials, details will be omitted. Once the belt hook temporary fixing band (1) is attached while being closely adhered to the vicinity of the lower surface of the loading frame of the truck with a certain tension, it does not need to be removed as it is, and therefore a material with weather resistance is used.

[0017] Figure 2(A) is a reference diagram showing that the truck bed hook is actually inserted through the bed hook through-hole (20) of the belt hook temporary fixing band (1), and this belt hook temporary fixing band is closely attached under the truck bed frame with a certain tension. Figure 2(B) is a reference diagram from the front direction of the truck at this time. Figure 3 is a reference photo showing that after only a part of the belt hook temporary fixing band (1) is pinched with fingers and slightly lifted partially from the bed frame to form an engagement space large enough to insert the J-shaped hook part, the J-shaped hook part is inserted into this engagement space and temporarily fixed while being engaged with the bed frame. As can be understood from this reference photo, the tension of the belt hook temporary fixing band (1) itself, which is closely attached to the bed frame with a certain tension, simply prevents the J-shaped hook part temporarily fixed to the bed frame from falling off. Figure 4 is a reference photo showing that after the ring part (wakka part) of the fiber rope for hanging weights is engaged with the bed hook, the tension of the belt hook temporary fixing band (1) itself simply prevents the ring part (wakka part) temporarily fixed to the bed hook from falling off.

[0018] Figures 5(A) to (C) are reference diagrams showing the procedure for engaging the engaging metal fittings (J-shaped or S-shaped hook parts) with the loading platform frame of the truck. Depending on the position of the loaded cargo on the loading platform, if the engaging metal fitting of the lashing belt is at a position where it engages with the loading platform frame instead of the loading platform hook, as shown in Figure 5(A), pinch a part of the belt hook temporary fixing band (1) at this position with your finger and lift it slightly downward to secure a slight engaging space that allows the insertion of the engaging metal fitting. When securing this engaging space, the belt hook temporary fixing band (1) is slightly pulled and displaced from both sides of the loading platform hook toward the center of the engaging space, but this displacement is sufficiently absorbed by the horizontally long notch of the loading platform hook through-hole (20) and the stretchability of the belt itself, so there is no problem. After engaging the engaging metal fitting inserted into the engaging space with the loading platform frame, if you release your finger from the belt hook temporary fixing band (1) pinched with your finger, due to the tension of the belt hook temporary fixing band (1) itself, as shown in Figure 5(B), the engaging metal fitting can be held in a state of being engaged with the loading platform frame, and it is possible to reliably prevent it from falling off due to its own weight. Of course, in this case, since an elastic rubber body or elastic fiber is used as the material of the belt hook temporary fixing band (1), it is possible to reliably prevent the engaging metal fitting from falling off. When engaging the engaging metal fitting (ring part) of the lashing belt, the loop part (wacker part) at the end of the fiber rope for hanging the ball or the metal wire with the loading platform hook, as shown in Figure 5(C), lift the corresponding part of the belt hook temporary fixing band (1) downward with your finger to secure a slight engaging space that allows the insertion of the engaging metal fitting from the loading platform frame, and then engage the ring part of the engaging metal fitting, the loop part of the fiber rope for hanging the ball, or the loop part at the end of the metal wire with the loading platform hook in the same way, and it is possible to reliably prevent these from falling off the loading platform hook.

[0019] Figures 6(A) to (G) are other external shape examples of the belt hook temporary fixing band (1) according to the invention of the present application. Figure 6(A) is configured with only a cut in the longitudinal direction (horizontal direction) without a cut in the short direction (vertical direction) of the cargo bed hook through hole (20). Originally, the cut in the short direction is for absorbing the variation in the protruding distance of the cargo bed hook from the cargo bed frame. Therefore, it is not necessarily required for trucks where the protruding distance of the cargo bed hook from the cargo bed frame can be ignored.

[0020] Figure 6(B) is an image diagram when the invention of the present application is commercialized, and the belt hook temporary fixing band (1) is wound in a roll shape. Since the truck driver (worker) can cut it to an arbitrary length according to the length of his own truck and use it, it is possible to use the belt hook temporary fixing band (1) according to the invention of the present application for all large and small trucks.

[0021] Figure 6(C) is a belt hook temporary fixing band (1) with continuous annular cargo bed hook through holes (20), and it is a shape that is easy to match the interval length between the cargo bed hooks of the truck. Also in this case, as a whole, it only needs to have the strength to hold the weight of the engaging fitting. Figure 6(D) is a shape combining an annular cargo bed hook through hole (20) and a slender connecting band. Also in this case, it only needs to have the strength to hold the weight of the engaging fitting.

[0022] FIG. 6(E) is a reference view of the belt hook temporary fixing band (1) composed of a fiber band among flexible materials. As other materials, a strip-shaped flexible reinforced plastic or a metal mesh may be used. In addition to the above materials, for example, the material of the band itself is a magnetic material like a rubber magnet, and the interval between the cargo bed hook through holes (20) adjacent to the cargo bed hook through hole (20) is configured to magnetically adhere to the cargo bed frame of the truck. In this way, it is possible to more firmly temporarily fix the belt hook of the fixing belt to the cargo bed frame at this magnetically adhering portion. Of course, it is not always necessary for the material itself to be a magnetic material, and small magnetic bodies may be arranged along the axial direction of the elastic band. Also, the strength of the above-mentioned magnetic material only needs to have a magnetic force sufficient to sufficiently temporarily fix and hold the general known weight of the belt hook (engagement fitting) to the cargo bed frame of the truck by the belt hook temporary fixing band (1). Since the specific strength of the magnetic material is a design matter, it is omitted. FIG. 6(F) shows continuous large and small annular cargo bed hook through holes (20) because the thickness of the cargo bed hook is thick or thin. Similarly, FIG. 6(G) shows large and small X-shaped cargo bed hook through holes. The size of how large or small is set to a size sufficient to sufficiently temporarily fix and hold the general known weight of the belt hook to be temporarily fixed. Since the specific numerical values are design matters, they are omitted. Note that all materials have flexibility and stretchability.

Industrial Applicability

[0023] Compared with the configuration according to the conventional example, the belt hook temporary fixing band (1) according to the present invention has the advantage that the number of components to be configured is small, the configuration is extremely simple, so it is inexpensive, and therefore it can be sold as a mass-produced product in many mass merchandisers. Further, as a great advantage of the belt hook temporary fixing band (1), by simply passing the cargo bed hook of the truck through the cargo bed hook through hole (20) and engaging it with the cargo bed frame of the truck, it is possible to directly use the existing fixing belts that many trucks already have. Therefore, it has the advantage that a great improvement in the fixing work can be achieved with a small cost.
