For example, as shown in FIG. 5, a watertight deck a is provided on which automobiles and the like are placed and stored, and lashing wires b extend from the automobile side to the deck a.

The lashing wire b has a hook member c at its end.
The hook member c is engaged with a locking device d to be locked to the deck a.

The locking tool d is bent into a semicircular cross section and attached to the deck a.
It consists of a metal fitting e welded onto the top and a ring f that connects the metal fitting e and the hook member c to each other.

[Problems to be solved by the invention] By the way, the conventional locking tool d is composed of a semicircular metal fitting e and a ring f, as described above.
Therefore, these two articles had to be combined and integrated on deck a, posing the problem of complicating article management.

Further, the ring f connecting the hook member c and the semicircular fitting e has an elongated annular shape along the semicircular fitting e,
For this reason, it is difficult to control the position of the hook member d. That is, as shown in FIG. 6, the ring f has a straight portion of length l that allows the movement of the hook member c, and allowing the movement of the hook member c in this straight portion means that the ring f This posed an unfavorable problem in terms of the strength of ring f, as it made the connection between ring f unstable and placed a load on ring f.

Therefore, the present invention was devised to effectively solve these problems, and it reduces the number of locking devices, facilitates the management and installation of the devices, and stabilizes the hook members and the deck. It is an object of the present invention to provide a hook fastening device for lashing wires that can be connected together to achieve high mass production and cost reduction.

[Means and effects for solving the problems] The present invention provides a lashing wire for locking a hook member provided on a deck etc. and curved at a predetermined curvature at the end of the lashing wire. In the hook locking device, the contact is folded downward from the upper central portion toward the deck etc. and defines a circularly opened engagement hole for inserting and engaging the hook member, and contacts the hook member. The portion is curved along the curvature of the hook member and has an opening peripheral portion, has a space portion for vertically movably accommodating the hook tip portion inserted therein, and has a lower portion extending radially outward. It is formed into a cap shape with a joint that is joined along the deck, etc., and the hook member at the tip of the lashing wire can be oriented at an arbitrary angle to the center of the hook locking device to stabilize it. It is possible to connect the hook member and the hook locking device.

[Example] An example of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, a deck 1 of a ship is provided for mounting and storing automobiles and the like.

Lashing wires 2 are extended onto the deck 1 as mooring cables for storing automobiles and the like. This lashing wire 2 has a hook member 3 at its tip, and is adapted to be stretched by engaging the hook member 3 onto the deck 1.

In particular, a hook locking device 4 for connecting the hook member 3 to the deck 1 is formed on the deck 1 by protruding to a predetermined height in a cap shape.

As shown in FIGS. 1 and 2, this hook locking tool 4 has a space A therein for accommodating the tip of the hook member 3, and the diameter gradually expands radially outward from the top downward. The lower part thereof has a joint part 5 which extends along the top of the deck 1 and is joined thereto. Reference numeral 6 indicates a welded portion 6 of the joint portion 5 extending along the deck 1, and the joint portion 5 is joined by arc spot welding.

Further, as shown in FIGS. 1 and 2, the hook locking tool 4 is formed with an engagement hole 7 for inserting and engaging the hook member 3 therein.

This engagement hole 7 is formed to have a smaller diameter than the lower part of the hook locking device 4, and is adapted to guide the tip of the hook member 3 to be inserted into the internal space A. Furthermore, by opening the engaging hole 7 in a circular shape facing upward at the top of the cap, the hook member 3 to be inserted can be oriented in the center and engaged, and a plurality of hook members 3 can be engaged. is made possible. That is, as shown in FIG. 1, the hook locking device 4 has an opening peripheral portion 8 that defines the engagement hole 7 and is folded back downward toward the deck 1 to contact and engage with the hook member 3. A space A is formed in which the tip of the hook member 3 inserted therein is accommodated so as to be movable up and down. Therefore, even if the extension angle Θ of the lashing wire 2 changes, the contact point of the hook member 3 can be positioned on the extension line of the lashing wire 2, and the extension angle Θ of the tension wire 2 can be set in a wide range. can.

Further, the contact portion of the opening peripheral portion 8 that contacts the hook member 3 has a curved surface that substantially matches the curvature of the hook member 3, as shown in FIG. Hook member 3
The hook member 3 inserted can be oriented toward the center of the engagement hole 7 by bringing the contact part of the opening peripheral part 8 curved along the curvature of the opening into surface contact with the inner diameter part of the hook member 3, and the hook member 3 can be oriented toward the center of the engagement hole 7. 3. Stable and reliable locking is possible.

Therefore, the height of the hook locking tool 4 and the engagement hole 7 are adjusted so that the lashing wire 2 is stretched forming an arbitrary angle θ and the hook member 3 is securely locked in the engagement hole 7. The caliber of the will be determined.

Such a cap-shaped hook locking device 4 is press-molded.

That is, as shown in Figure 4, for example 3.2
A hole 4b for forming an engagement hole 7 is punched in the center of a thin disk material 4a of about mm size, and a notch is formed to form a space A and a joint 5 by raising the center. 4c is formed to be open to the outer peripheral side. In the illustrated example, four notches 4c are formed.

Therefore, the remaining portion between these notches 4c is folded back radially outward along the deck 1 to form the joint portion 5 of the hook engaging tool 4. Furthermore, the notch 4c forms an opening 9 that communicates between the inside and outside of the hook locking device when the hook locking device 4 is joined onto the deck 1.

In this way, the present invention forms a hook locking tool 4 that is protruded in a cap shape on the deck 1 and locks the lashing wire 2 having a hook member 3 at the end, so that the hook locking tool 4 can be integrated into a single unit. Therefore, goods management can be done easily.
