Description

[Detailed Description of the Invention] The present invention relates to a load fastening device such as a packing string or a band-like object.

Conventional load tightening methods for packaging, etc. include: (1) A tension tightening device that tightens by simply pulling in one direction, like a belt fitting for pants.

(2) A reversing tightening device that tightens the belt by pulling it and then inverts the fitting itself to tighten it even more firmly.

(3) A winding and tightening device that combines a latch, a lever, a winding drum, etc., and winds up the belt by reciprocating the lever.

etc. are known.

Among these devices, the reverse tightening device is superior as it can be expected to produce greater tightening force with simple work, and can be done at a lower cost.

However, the conventional reversing tightening device has drawbacks such as the tightening tool being reversed due to vibrations of the packaged item, causing the package to break off midway.

For example, the load fastener described in Japanese Utility Model Application Publication No. 52-20487 is not of the type that exerts a self-reversal prevention force, so an engaging means must be provided to prevent the lever from reversing.

Therefore, an object of the present invention is to provide a load tightening tool that reliably prevents the metal fitting body from being reversed after being reversed, and also allows for easy lifting of the metal fitting body.

According to the present invention, in a load tightening device, a fixed side belt is attached to one end of a metal fitting body via a rotatable bracket, a free side belt is attached to the other end, and a fixed object is tightened by reversing the metal fitting body. There is a belt loop hole on the top of the metal fitting body, and two parallel holes are cut out in the top surface.
Holes for attaching the bracket are formed on both sides of the bracket at a position away from the tip, and a stopper is provided at one end of the hole to prevent the bracket from rotating below the bottom edge of the metal fitting body. The bracket is provided with a bent portion to be inserted into the hole, the stopper is provided on one end side of the metal fitting body to which the stationary side belt is attached from the hole, and the stopper is provided on the other end of the metal fitting body with a finger extending laterally. A hanging member is provided.

Therefore, the distance between the hole for tightening the bracket, which is the point of force applied to the bracket, and the tip of the main body, which is the point of force applied to the free side belt, is far apart, and a relatively large force is applied in the direction of preventing reverse rotation. do.

Furthermore, the bracket is held securely by being sandwiched between the stoppers on both sides, and will not be reversed due to vibration or the like.

Further, the stopper has a function of preventing the bracket from being separated from the hole, and therefore, a reliable state of connection can be maintained.

The finger hook member makes it easy to reverse the tightening operation even if the tension of the front belt is increased, and therefore the tightening force can be increased.

In addition, since the member of this finger hook is spread out in all directions, it receives a large self-reversal prevention force over a wide area after tightening, making it difficult to damage the item.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an overall perspective view of the load tightening device according to the present invention, and a bracket 2 is fixed to the left side of the fitting main body 10 in the drawing, and one end of the belt 3 on the fixed side is sewn to the bracket 2. A metal fitting 6 is also attached to the other end of the belt 3 via a sewn portion.

Further, a free side belt 4 is attached to the right side of the fitting main body 10 in a manner described later, and its free end 41 extends rightward in a free state.

Further, a metal fitting 6 is attached to the belt 4 in the same way as the belt 3 on the fixed side.

The details of the metal fitting main body 1 are shown in FIG. 2, and the cross-sectional shape is channel-shaped as shown in FIG.

As shown in the figure, two parallel belt passing holes 11 and 12 are formed in the upper surface 1a by cutting out a part of the upper surface 1a.
A hole 13 for attaching the bracket 2 is bored in both side walls 1b, and a lower side 19 is provided on the right side of the drawing.
A finger hook member 14 is provided at the location.

On the other side, on the left side in the drawing 190 and with belt through holes 11, 1
Stoppers 15, 15 are located below the main body 1 in an L-shape.
(FIG. 4), and the open end 15' of the stopper 15 may be curved as shown in FIG. 4A so that a bracket 2, which will be described later, can be easily held on the web portion 15a of the stopper 15.

Reference numeral 16 denotes the tip of the main body fitting, and the lower side 19 extending from the tip 16 to the stopper 15 is formed in a curved shape, and the left and right side walls 1b of the main body fitting 1 have a height H of the tip.
1 is larger than the height H2 of the rear end.

A non-slip protrusion 17 is further provided on the rear end side of the upper surface 1a of the main body 1, and a belt passage portion 18 is formed inside the protrusion 17 as shown in FIG.

The width W of this belt passage portion 18 is approximately equal to or slightly larger than the width of the belt.

FIG. 3 shows a bracket 2 connected to a bracket mounting hole 13 formed in the metal fitting body 1, and a fixed side belt 3 connected to the bracket 2 by a sewn portion 5.

The bracket 2 has a substantially C-shaped planar shape and is made of an elastic metal material, and the tip of the bracket 2 has a mounting oil sump 21a.
t 2 l b is formed.

It is preferable that the bracket material has a circular cross section.

The above-mentioned target portions 21 a, 2 l b are the metal fitting main body 1.
The side attachments are inserted into the respective holes 13, and are connected and held by the elastic force of the bracket, so that the two are rotatably connected.

As mentioned above, the stationary belt 3 is connected to the bracket 2 via the ring-shaped part 31 by the sewn part 5.

Next, attachment of the belts 3 and 4 will be explained.

The fixed side belt 3 is attached to the bracket 2 as described above, and then attached to the hole 13 of the main body fitting 1. At this time, as shown in FIG. 5, the bracket 2 can be rotated around the hole 13, so first 2 to the metal fitting main body 1 at the position shown by 2a, and then rotate the bracket 2 in the direction of the arrow X and insert it into the stopper 15.

On the other hand, the free end 41 of the belt 4 on the free side is guided from the rear end of the metal fitting main body 1 through the passage part 18 to the tip, and then passed through the belt passage hole 11 from the upper surface 1a of the main body 1 to the back side, and is then separated from the back side. Pass through the belt loop hole 12 and expose it to the top.

After attaching the belts 3 and 4 in this manner, the load tightening work is performed.

Next, load tightening work will be explained with reference to FIGS. 6 and 7.

First, the metal fitting main body 1 is placed so that the upper surface 1a is in contact with the object 7 to be fixed, that is, upside down, as shown in FIG.

Next, the hook hooks the metal fittings 6, 6 onto the pallet 8, and the free end 41
Pull it in the direction of arrow Y to take up the slack in the belt.

Next, after picking up the finger hook member 14 of the metal fitting body 10, the non-slip protrusion 17 is held down and the metal fitting body 1 is turned over using the boxwood body tip 16 as a fulcrum.

Through the above operations, the belt is further tensioned, and secure and firm tightening of the load is completed in the state shown in FIG.

To release the tightening force, simply pull up the free end 41 or lift the metal fitting body 1.

FIG. 8 shows how force is applied after tightening is completed.

In other words, the attachment hole 13, which is the point of force on the bracket 2 side, and the main body tip 16, which is the point of force applied to the free side belt 4, are separated from each other. There is a force trying to turn it clockwise.

This force becomes a self-reversal prevention force.

However, the above-mentioned preventive force alone is not reliable and may reverse due to vibrations, immutability, etc. during transportation.

However, in this invention, as shown in FIGS. 1 and 4, since the bracket 2 is securely held by the stopper 15, it is possible to prevent the bracket from reversing.

This stopper 15 also serves to prevent the bracket from being pulled out to the outside of the bracket mounting hole, so that an extremely reliable connection state can be maintained despite simple installation.

In addition, since the present invention has a finger hook member attached to the metal fitting body, the tension of the front belt can be increased during tightening, so that the tightening force when tightening the load can be made stronger.

Furthermore, when implementing the present invention, since the height Hl of the tip part is thicker than the height H2 of the rear end part, the tightening torque in the two directions of the arrows is applied after the work is completed, as shown in Figure 8. It becomes larger and can prevent self-reversal.

Further, it is preferable that the lower side 19 near the tip 16 of the main body is curved to facilitate the reversing operation of the metal fitting main body 10.

As described above, according to the present invention, the stopper that holds the bracket for attaching the stationary side belt is provided, so that
Self-reversal can be prevented, and finger hooks are provided on both sides of the metal fitting body, so it is easy to reverse the process when tightening.Since this finger hook is located at the bottom side 19, tightening can be done later using these fingers. There is no risk of the hanging member being touched by objects and being reversed.
