The suspension hook 21 has a lock mechanism 40 as a lock means for restricting the rotation of the hook member 12 with respect to the hook support member 13 in the closed position and the open position. That is, the lock mechanism 40 includes the rotation shaft insertion hole 28, the support plate 37, the rotation shaft 39, the holding plate 41, and the spring 46.

As shown in FIG. 4, the rotation shaft insertion hole 28
The other side plate 31 of the hook support member 13 which faces the insertion portion 24 with the insertion portion 24 interposed therebetween has a large-diameter hole 32 formed outside thereof and a smaller-diameter hole continuously formed inside the large-diameter hole 32. The medium-diameter hole 33 and the small-diameter hole 34 formed in the one side plate 30 with a smaller diameter than the medium-diameter hole 33.
And

As shown in FIG. 3, the support plate 37 has a substantially rectangular shape and is joined to an outer surface of the other side plate 31 at a substantially central portion. An upper hole 35 and a lower hole 36 are formed in the support plate 37 so as to correspond to the support shaft insertion hole 29 and the large-diameter hole portion 32 and have the same diameter and communicate with each other.

As shown in FIG. 4, the rotating shaft 39 has a small-diameter shaft portion 42 that fits into the small-diameter hole portion 34 of the rotating shaft insertion hole 28 along the axial direction thereof, and is smaller than the small-diameter shaft portion 42. A large-diameter shaft portion 43 having a large diameter and fitted with the medium-diameter hole portion 33 and a large-diameter shaft portion 44 having a larger diameter than the medium-diameter shaft portion 43 and fitted with the large-diameter hole portion 32 are sequentially formed. Is formed. Small diameter shaft 42
Has an axial length from the outer side surface of one side plate 30 to the inner side surface of the other side plate 31.
The large-diameter shaft portion 44 has an axial length from the inner surface of the other side plate 31 to the outer surface of the support plate 37. Also, along the axial direction, the large-diameter shaft portion 44 and the medium-diameter shaft portion 4
A recess 45 for receiving a spring 46 at a depth of halfway
Are formed.

The lock mechanism 40 is connected to the rotating shaft 3

0, whereby the pivot shaft hole 19 of the hook member 12 coincides with the medium-diameter hole portion 33 of the hook support member 13, and as a result, the biasing force of the spring 46 causes the small-diameter shaft portion 42 protrudes from one side plate 30, and the middle diameter shaft portion 43 fits into the rotation shaft hole 19, so that the support shaft 38 does not come off from the closed side recess 50, and the hook member for the hook support member 13 12 is restricted. Therefore, if the hook member 12 is rotated to the closed position, the rotation of the hook member 12 relative to the hook support member 13 is automatically locked.

Then, in order to release the lock and rotate the hook member 12 with respect to the hook support member 13 as shown in FIG. 6, the small-diameter shaft portion 42 resists the urging force of the spring 46. Then, the hook member 12 may be rotated. That is, when the small diameter shaft 42 is pressed against the urging force of the spring 46, the small diameter shaft 42 is
, The support shaft 38 is loosely fitted in the guide groove 18 in which the closed-side recess 50 is formed. When the hook member 12 is rotated with respect to the hook support member 13 as it is, the guide groove 18 is moved along the support shaft 38 as shown in FIG.
The lower inner peripheral surface abuts on the small-diameter shaft portion 42 and
3 is restricted from moving in the axial direction. Therefore, the small diameter shaft portion 42
The lock is easily released by a simple operation of only pressing the hook member 12 with respect to the hook support member 13.
Can be rotated.

Then, as shown in FIG.
When the hook 2 is turned to the open position, the support shaft 38 is again received in the open-side recess 51 of the guide groove 18 by the weight of the hook member 12, as shown in FIG. The rotation shaft holes 19 of the twelve holes coincide with the medium-diameter holes 33 of the hook support member 13. As a result, the biasing force of the spring 46 causes the small-diameter shaft 42 to protrude from the one side plate 30 and The intermediate shaft portion 43 fits into the rotation shaft hole 19, so that the support shaft 38 does not come off from the open side concave portion 51, and the rotation of the hook member 12 with respect to the hook support member 13 is regulated. Therefore, if the hook member 12 is rotated to the open position, the rotation of the hook member 12 with respect to the hook support member 13 is automatically locked. After unlocking this lock,
As shown in FIG. 6, in order to rotate the hook member 12 with respect to the hook support member 13, the small-diameter shaft portion 42 is pressed against the urging force of the spring 46 in the same manner as described above.
What is necessary is just to rotate the hook member 12.

And, in such a hanging hook 11,
The hook member 12 can be rotated so as to be inserted through the insertion portion 24 of the hook support member 13, and
A support shaft 38 serving as a fulcrum of the hook member 12 with respect to the hook support member 13 and a rotation shaft 39 serving as a fulcrum of the hook member 12 with respect to the hook support member 13 are independent of each other without being restricted by each other. Because the hook member 12 is provided with respect to the hook support member 13,
The rotation can be performed with the rotation shaft 39 below the support shaft 38 as a fulcrum. Therefore, in the state in which to position the hook member 12 to the open position, it can be further retracting the hook member 12 relative to the hook support member 13, insole
An optimal posture for smoothly inserting and pulling out the hook member 12 from the hole in the iron plate can be achieved.
Therefore, the insertion and withdrawal of the hook member 12 into and from the hole in the iron sheet can be performed smoothly and reliably.
Safe work can be ensured.

Further, the hook member 12 is connected to the hook supporting member 1.
At the time of rotation with respect to 3, the guide groove 18 formed in the hook member 12 is rotated so as to be guided along the support shaft 38. Therefore, the hook member 12 can always be rotated on the same rotation locus, so that when the hook member 12 is located at the open position, the hook member 12 is always optimally adjusted with respect to the hook support member 13. Can be in a posture. Therefore, reliable insertion and removal of the hook member 12 with respect to the hole of the iron plate can be ensured.

Further, in the hanging hook 11, when the hook member 12 is attached to the iron sheet and lifted, the tip part 14 of the hook member 12 is hooked into a hole of the iron sheet ,
Laying in a state in which by rotating the hook member 14 in the closed position
When the iron plate is lifted, the iron plate can be satisfactorily lifted without coming off the hook member 12. In addition, in this lifting operation, the hook member 12 is automatically locked in the closed position by the operation of the lock mechanism 40, so that safer and more reliable lifting can be achieved. Also, when removing the hook member 12 from the insole griddle, it is pulled out of the distal end portion 14 of the hook member 12 in a state in which by rotating the hook member 12 to the open position from the hole of the insole iron plate, removing the hook member 12 good Can be. In addition, in this removal operation, the hook member 12 is automatically locked at the open position by the operation of the lock mechanism 40, so that safer and more reliable removal can be achieved.

Next, a method of using such a hanging hook 11 will be described with reference to FIGS.

In order to lay the iron plate 47 using the hanging hooks 11, first, as shown in FIG.

Can be achieved.

Thereafter, the rotating shaft 39 is pressed to release the lock at the open position, and the hook member 12 is rotated to the closed position and locked, and as shown in FIG. By raising 11
The iron plate 47 is lifted. After being transported to a predetermined place by a crane, the hanging hook 11
, The hook member 12 is pulled out of the hole 49 of the iron sheet 47 after the iron sheet 2 is lowered.

In this pulling-out, first, as shown in FIG. 14, the lock in the closed position is released by pressing the rotation shaft 39, and the hook member 12 is rotated and locked to the open position. Then, as shown in FIG.
The hook member 12 is pulled out of the hole 49 by rotating the hanging hook 11. Also in this drawing, since the central portion 16 is formed in a substantially circular cross section or a substantially elliptical cross section as shown in FIG. 5, the outer peripheral surface of the central portion 16 is formed within the hole 49 of the iron sheet 47. Even if it is pulled out while being in sliding contact with the peripheral edge, the contact resistance generated between the inner peripheral edge of the hole 49 and the outer peripheral surface of the central portion 16 can be reduced, so that a smooth extraction can be realized, and work stability and Efficiency can be improved. Then, as shown in FIG. 16, when the hook support member 13 is in a posture oriented substantially in the vertical direction, the distal end portion 14 of the hook member 12 is pulled out from the hole 49 of the iron sheet 47, thereby the hanging hook Removal of 11 ends.

When the iron plate 47 is laid by using such a hanging hook 11, when the hook member 12 is located at the open position, the hook member 12 is more drawn into the hook support member 13. As a result, the hook member 12 can be smoothly pulled out of the hole 49 of the iron sheet 47, so that the suspension hook 11 can be connected to the iron sheet 4.
By rotating the hook member 12 along the hole 49, the distal end portion 14 of the hook member 12 can be pulled out smoothly and reliably. For this reason, the distal end portion 14 of the hook member 12 cannot be sufficiently removed, and when the lifting hook 11 is lifted up again by the crane at the end of the work, the distal end portion 1 of the hook member 12 is removed.
The safe operation is ensured without the risk that the iron sheet 47 is temporarily lifted while the 4 remains locked in the hole 49 of the iron sheet 47, and then the lock is released by its own weight and the object iron falls. Can be.
