Taiwan Patent No. 250956 Taiwan Registered Utility Model No. 284618 Taiwan Patent No. 245730

  In order to stably tie the container 4 to a ship or the like using the container lashing device, the connection module 8 has a predetermined structural strength and a predetermined wall thickness for mounting the pins 3 so as to be strong. Must. Also, the pin 3 must have a structural strength for positioning the head 2 with respect to the base 1 and holding it connected.

  In addition, when the adjacent containers 4A and 4B are secured to a ship or the like while the lashing rods 7 intersect and contact each other, the diameter width of the communication hole 410 is used in order to make maximum use of the accumulation space on the deck. In addition, since the distance d (FIG. 2) of the connecting module 8 to the corner bracket 41 is limited by the mounting of the pin 3, the hook block 201 being attached to the corner bracket 41, the positioning of the anchor block 203, etc., the use of the container lashing device As the period becomes longer, the lashing rod 7 becomes worn as the recess 103 is formed as shown in FIG. Therefore, there is a problem that the lashing rod 7 breaks due to deformation, and the loaded container may collapse.

  In addition, since the standards (length, width, height) of containers differ depending on the capacity of the ship or vehicle, containers 4A and 4B (FIGS. 3 and 4) having different standards are stacked on the deck depending on the case. Sometimes, for example, the lashing rods 7 cross each other and come into contact with each other by changing the mooring position of the lashing rod 7 by moving the installation position of the pillar 91 so as to increase the distance A1 (FIG. 1) from the container of the pillar 91. To avoid this, the installation cost of the pillar 91, the lashing work cost, and the accumulation space on the deck are spent.

  Further, a connection module 8A (FIG. 4) provided with a slot 210 formed as a space in which the pin 3 can move in the head 2 is also used conventionally. In this connection module 8A, the base 1 and the head 2 must have a predetermined structural strength and a predetermined thickness for mounting the pins 3, and the moving space of the pins 3 is limited, which is still improved. There is a place to be.

  Embodiments according to the present invention will be described below with reference to the accompanying drawings. In the drawings, substantially the same members are denoted by the same reference numerals.

  FIG. 5 is a diagram schematically showing an example of the container lashing device 200, and the container lashing device 200 according to this example relates to the embodiment of the present invention that is engaged with the anchoring hole 40 of the corner fitting 41. The connecting module 100 includes a lashing rod 7 in which the connecting module 100 is integrally provided at one end thereof, and a turnbuckle 6 having one end connected to the other end of the lashing rod 7. Since this container lashing device 200 has substantially the same configuration as the conventional container lashing device except for the connection module 100, detailed description thereof is omitted.

Example 1
The connection module 100 according to the present embodiment includes a base 10 and a head 20. The base 10 is usually of the same nature as the lashing rod 7 and is, for example, made of metal and provided so as to be integrally connected to one end of the lashing rod 7. The head 20 is an integrally molded product by pressure molding, for example, and is formed in a hook shape so as to be engaged with the corner bracket 41.

  6 is a longitudinal sectional view schematically showing the configuration of the connection module 100 according to the first embodiment, and FIG. 7 is an assembly perspective view showing the connection module according to the first embodiment. The base 10 is connected to the long axis X of the lashing rod 7 so as to be vertically extended, and a connecting portion 11 connected integrally with the lashing rod 7 and an extension on the opposite side of the connecting portion 11 along the long axis X. Part 12. The base 10 has an annular portion 17 between the connecting portion 11 and the extending portion 12. The annular portion 17 has a through hole 170 penetrating from the first side surface 13 on the container 4 side toward the second side surface 14 away from the container 4. (See FIG. 7). In this form, the annular portion 17 has a substantially rectangular outer shape and has an inner peripheral surface 150 that defines a through hole 170. The annular portion 17 includes a first through-wall wall 150a having a larger thickness and a second passage having a smaller thickness so that a step 171 is formed on the inner peripheral surface 150 with different thicknesses. And a hole wall 150b.

  The through-hole 170 is formed in a non-circular shape so as to be defined by the inner peripheral surface 150, and is a direction along the first axis L1 with the first axis L1 perpendicular to the major axis X as the central axis. One having a smaller inner diameter including the first opening 151 on the first side face 13 side due to the first through-hole wall 150a and the second through-wall wall 150b having different thicknesses while penetrating in the first axial direction. The first through hole 15 and the second through hole 16 having a larger inner diameter including the second opening 152 on the second side face 14 side so as to communicate with the first through hole 15 are respectively formed. Has been.

  In this example, the first through hole 15 has, on the second through hole 16 side, for example, a first length e1 along a first length direction that is parallel to the long axis X, and a first length e1. It is formed in a substantially rectangular shape so as to have a first width w1 along a first width direction which is a direction orthogonal to the length direction and the first axial direction.

  For example, the head 20 is integrally formed of a metal material, and is not in the first axial direction, and has a second axis L2 centered on the second axis L2 that intersects the first axis L1 and the long axis X. The through-hole 170, that is, the first through-hole 15 and the second through-hole 16 are rotatably supported by the base 10 so as to extend along the second axial direction that is a direction along L 2. Is provided. In this embodiment, the head 20 is provided to extend around the second axis L2 so as to penetrate the first through hole 15 and the second through hole 16 and be pivotally supported by the base 10. When the head block 22 is connected to the base 10, the head block 22 is located outside the first side surface 13 and is engaged with the mooring hole 40, so that the head block 22 faces upward toward the outside of the first through hole 15. The hook block 21 formed in a curved shape and the head block 22 downward so that the hook block 21 is held without swinging with respect to the corner fitting 41 when the hook block 21 is engaged with the anchoring hole 40. And an anchor block 23 formed to protrude.

  The head block 22 includes a shaft portion 221 that is slidably movable in the first through hole 15 so as to extend along the second axial direction, and a first portion that defines the first through hole 15. From the second through hole 16 side of the shaft portion 221 so as to be engaged with a step 171 formed between the through hole wall 150a and the second through hole wall 150b defining the second through hole 16. And a locking portion 222 provided so as to protrude perpendicular to the second axial direction.

  The shaft part 221 has a substantially rectangular vertical cross section in the second axial direction. In this example, the engaging portion 222 is engaged with the second through-hole 16 so that the portion engaged with the second through-hole 16 is formed in a substantially cross shape, and is along the second length direction which is a direction perpendicular to the second axial direction. A first width w1 along a second length e2 that is greater than the first length e1 and a second width direction that is perpendicular to the second length direction and the second axial direction. A larger second width w2.

  In this embodiment, a part of the second through-hole wall 150b, for example, a lower peripheral portion on the connecting portion 11 side is continuously extended from the first through-hole wall 150a, and the other portion, that is, an upper peripheral portion on the extended portion 12 side. However, the first through-hole wall 150a is thin so that a step 171 is formed.

  The locking part 222 projects from the upper part of the shaft part 221 toward the upper part of the second through-hole wall 150b in a brim shape perpendicular to the second axis L2 and forms a step 171 in the second through-hole 16. The upper block 223 that is formed to be locked, and a step 171 in the second through hole 16 that protrudes from both sides of the shaft portion 221 toward the both sides of the second through hole wall 150b. Side blocks 224 and 224 formed so as to be locked are provided.

  In this way, the locking portion 222 has a second length e2 that reaches the upper block 223 along the second length direction, which is larger than the first length e1, and the sides on both sides along the second width direction. Since the second width w2 between the blocks 224 and 224 is larger than the first width w1, it is engaged with the step 171 formed by the first through-hole wall 150a and the second through-hole wall 150b. In this way, it is localized at the second through hole 16. Therefore, the head 20 can be prevented from being easily detached from the base 10.

  Since the connecting module 100 configured as described above is configured so as not to provide the pin 3 as in the conventional connecting module 8, it is not necessary to open the slot 210, the pin hole 204, or the like in the head 20. Is simple and has a predetermined structural strength.

  In addition, the head 20 is fixedly connected so that the hook block 21 is inserted into the anchoring hole 40 through the communication hole 410 and is anchored by the anchor block 23 so that the container 4 is positioned with respect to the deck. The stop portion 222 is engaged with the second through hole 16 by the side blocks 224 and 224, whereby a distance D is formed between the base 10 and the corner fitting 41 as shown in FIG. The

  When the conventional connecting module 8 is positioned with respect to the container 4, the rotation of the pin 3 is limited, and the connecting module 8 </ b> A is also limited in the movement of the pin 3 in the slot 210 by the space of the slot 210. There is a problem that the lashing rod 7 is worn when the seven are used crossing each other. On the other hand, since the connection module 100 according to the present invention does not use pins or the like, the problem due to the pins or the like is solved, so that a container lashing device that can be used by crossing the lashing rods 7 is obtained. .

  Moreover, since the distance D with respect to the container 4 is larger than the distance d with respect to the container 4 of the conventional connection module 8, even when the lashing rod 7 is used crossing, wear of the lashing rod 7 is greatly reduced, and the pillar 91 is also used. The distance A1 with the container 4 can be used without changing.

  In addition, since the structure of the connecting module 100 according to the present invention is simpler than that of the conventional structure, the manufacturing cost can be reduced, and the structural strength is high although it does not change in size. The container lashing device using the connection module 100 can be used for a long time.

  Next, a method for manufacturing the connection module 100 according to the present invention will be described with reference to the accompanying drawings.

  In the first step, as shown in FIG. 8, a base rough molded body 10 ′ in which a predetermined through-hole 15 ′ that has been previously formed into a shape of the base 10 by performing drilling or the like is formed, and a predetermined A head 20 formed into a shape is prepared.

  The rough base molded body 10 ′ is formed, for example, so as to extend along the long axis X of the lashing rod 7, and includes a connecting end portion 11 ′ as a connecting portion connected to the lashing rod 7, and the long axis X The connecting end 11 ′ and the extending end 12 ′ opposite to the connecting end 11 ′, and between the connecting end 11 ′ and the extending end 12 ′ perpendicular to the long axis X. An annular portion 17 ′ having a through hole 15 ′ penetrating therethrough, and the annular portion 17 ′ includes a first side surface 13 ′ and a second side surface 14 ′ which are parallel to the long axis X and opposite to each other. Have. The through hole 15 ′ includes a first through hole 151 ′ on the first side surface 13 ′ side and a second through hole 152 on the second side surface 14 ′ side having a diameter larger than that of the first through hole 151 ′. ′, And is extended along a first axial direction that is defined by an inner peripheral surface 150 ′ of the annular portion 17 ′ and that is along a first axis L1 perpendicular to the major axis X. The cross section including the first length direction parallel to the major axis X is substantially elliptical so that the first length e1 along the first length direction, the first length direction, and the first length And an original width w along the first width direction which is a direction orthogonal to the axial direction of the first width direction.

  As shown in FIGS. 6 and 7, the head 20 is formed by being extended with the second axis L2 as the central axis as described above, and includes a hook block 21, a head block 22, The head block 22 includes a shaft portion 221 and a locking portion 222 that pass through the through hole 15 ′. The locking portion 222 includes the upper block 223 and the side blocks 224 and 224. And have. The locking portion 222 has a second length e2 along a second length direction that is a direction orthogonal to the second axial direction, and a right angle with each of the second length direction and the second axial direction. And a second width w2 along a second width direction that is a direction. Here, the second length e2 is a length from the lower end of the locking portion 222 to the upper end of the upper block 223, and is larger than the first length e1. The second width w2 has a width between the two side blocks 224 and 224 and is slightly smaller than the original width w.

  In the second step, as shown in FIG. 9, the second axis L2 of the head 20 obliquely intersects the first axis L1 and the hook block 21 is above the head block 22. Then, the upper block 223 is inclined and the head 20 is passed through the through hole 15 ′ while being swung with respect to the base rough molded body 10 ′.

  In the third step, as shown in FIG. 10, the upper block 223 has the first through hole 151 ′ and the second through hole in a state where the second axis L2 is substantially parallel to the first axis L1. The shaft portion 221 is passed through the through-hole 15 ′ while moving the head 20 relative to the base rough molded body 10 ′ so as to protrude to the outside of the second side surface 14 ′ through 152 ′. Thereby, the head 20 is positioned with respect to the base rough molded body 10 ′.

  In the fourth step, as shown in FIG. 11, both sides of the annular portion 17 ′ are pressed toward the shaft portion 221 along the short axis direction that is a direction along the short axis Y perpendicular to the long axis X. Thus, the base rough molded body 10 ′ is deformed so as to be molded into the base 10. Here, the substantially elliptical annular portion 17 ′ is formed into a substantially rectangular annular portion 17, and the elliptical through hole 15 ′ is formed into a substantially rectangular through hole 170. The first through hole 151 ′ is a first through hole 15 having a first length e1 and a first width w1, and the second through hole 152 ′ is a second through hole 15 ′. It becomes a through hole 16. Note that the second width w2 of the locking portion 222 is slightly smaller than the original width w of the through hole 15 ′ so that the locking portion 222 cannot pass through the first through hole 15, and the second width w2 Is longer than the first length e1, and the second width w2 is larger than the first width w1. As described above, the locking portion 222 passes through the first through hole 15 and the step 171 formed by the second through hole 16 by the first through wall 150a and the second through wall 150b. Engage and localize.

  Through the above steps, the connection module 100 in which the head 20 is pivotally connected to the base 10 is manufactured. And the connection module 100 is connected with the end of the lashing rod 7 via the base 10, and a container securing apparatus is obtained.

  Needless to say, the locking portion 222 is not limited to the illustrated shape because the locking portion 222 only needs to be shaped to be locked and fixed by the second through hole 16 in the through hole 170.

(Example 2)
FIG. 12 illustrates the configuration of the connection module according to the second embodiment. In the first embodiment, the locking portion 222 is formed in a substantially cross shape, whereas in the second embodiment, the locking portion 222A of the head 20A is formed so as to cover the continuous end surface with the shaft portion 221. The block 223 protrudes from the upper part of the shaft part 221, the down block 223A protrudes from the lower part of the shaft part 221, and the side blocks 224A and 224A protrude from both sides of the shaft part 221 in a flange shape. The peripheral surface is substantially rectangular.

  Since the second length e2 is longer than the first length e1 and the second width w2 is larger than the first width w1, the locking portion 222A formed in this way (see, for example, FIG. 7). It can be positioned by being engaged with a step between the first through hole 15 and the second through hole 16. Therefore, the head 20A can be connected to the base 10 so as to be rotatable and non-detachable.

(Example 3)
FIG. 13 illustrates a configuration of a connection module according to the third embodiment. In this example, the locking portion 222B includes an upper block 223B formed so as to protrude from the upper portion of the shaft portion 221 and a side block 224B, 224B formed so as to protrude from both sides of the shaft portion 221. And is formed in a substantially square shape.

  In the locking part 222B formed in this way, the second length e2 is longer than the first length e1 and the second width w2 is larger than the first width w1 as in the above example. (For example, refer to FIG. 7), it can be positioned by being engaged with a step between the first through hole 15 and the second through hole 16. Therefore, the head 20B can be connected to the base 10 so as to be rotatable and non-detachable.

  Since the connection module 100 according to the present invention configured as described above is not reduced in its structural strength, when used in a container lashing device, the container lashing device can be used for a long time. Since the container lashing device using the connection module 100 according to the present invention is not worn out to the extent that the lashing rod 7 is used in an intersecting manner, the pillar 91 installed on the deck is installed. It can be used as it is without moving its position, and it does not take up space to install containers.
