  The second spring 90 is a coil spring, and is disposed in the second spring accommodating portion 48 of the hook 40, and urges the hook 40 to rotate in the closing direction. The second spring 90 is disposed coaxially with the hook 40, and one end 92 abuts on the case 20 and the other end 94 abuts on the hook 40 and urges in the closing direction.

  Here, returning to FIG. 2 and FIG. 3, the relationship between these members will be described. The rotation axes of the hook 40, the first link 60, and the second link 70 are arranged in parallel. The hook 40 is pivotally supported so that the rotation is transmitted to the arm 64 of the first link 60 and the hook engaging portion 76 of the second link 70 by the protrusion 50. The arm 64 engages with the hook 40 and can rotate the hook 40 in the opening direction by the rotation of the first shaft portion 62 in the first direction.

  The insertion / removal portion 74 of the second link 70 is engaged with the insertion / removal portion 68 of the first link 60, and the rotation of the second link 70 is transmitted to the first link 60. As shown in FIG. 3A, the pin 80 is provided to be inclined with respect to the bottom surface 32 of the case 20 and projects toward the first link 60.

  FIG. 10 is a diagram for explaining the operation of the hook 40. In FIG. 10A, the hook 40 is in a first state in which it is accommodated in the case 20 and closed. When the hook device 10 is not used, the hook 40 is closed.

  FIG. 10B shows a state in which the user presses the depression 44a of the hook 40 and the hook 40 is pushed from the first state to a predetermined position in the closing direction. Then, the rotation restriction in the heart cam mechanism 66 is released.

  FIG. 10C shows a second state in which the hook 40 is opened and stopped from the first state. In the second state, the hook 40 is not fully opened, but is about 70 to 80% open, so that the user can hang an object to be hooked on the hook 40.

  FIG. 10D shows a third state where the hook 40 is further opened from the second state. When the object to be hung is hung in the second state, the weight of the object to be hung is applied, and the hook 40 is further opened to stop in the third state. The hook 40 comes into contact with the stopper portion 38 of the case 20 and stops.

  In this third state, the engagement between the protrusion 50 of the hook 40 and the arm 64 of the first link 60 is disengaged. Since the first spring 84 that rotates the hook 40 in the opening direction is provided on the first link 60, the first spring 84 does not act on the hook 40 when the engagement between the protrusion 50 and the arm 64 is released. Therefore, when the object to be hung on the hook 40 in the third state is removed, that is, when the hook 40 is in a free state, the hook 40 is rotated in the closing direction by the second spring 90 and returns to the first state. In this way, the user can open and use the hook 40 only by pressing the hook 40 once. Further, after the hook 40 is used, the hook 40 is automatically closed from the third state. 40 opening / closing operations can be reduced. Hereinafter, each member in operation and in each state will be specifically described.

  FIG. 11 is an explanatory diagram for explaining the rotation restricting means in the first state. As shown in FIG. 11A, the pin 80 is attached to the case main body portion 22 and is disposed so as to be inclined with respect to the bottom surface 32.

  11B, the hook 40 is in the first state, and the heart cam mechanism 66 is engaged with the overhanging portion 82 of the pin 80 as shown in this figure. The first link 60 is biased in the first direction 85 by the first spring 84. When the arm 64 rotates in the first direction 85, the protrusions 50 that engage with the arm 64 are rotated together to rotate the hook 40. However, the rotation of the first link 60 is restricted by the engagement between the protruding portion 82 of the pin 80 and the holding portion 66b of the heart cam mechanism 66. As a result, the hook 40 can be held in the closed first state.

  FIG. 12 is a diagram illustrating a movement locus of the overhanging portion 82 that relatively moves in accordance with the rotation of the first link 60. In the first state shown in FIG. 10A, the overhanging portion 82 takes the first position 102 engaged with the holding portion 66b.

  Next, in a state where the operation plate portion 44 shown in FIG. 10B is pushed in the closing direction, the engagement between the overhang portion 82 and the holding portion 66b is released, and the overhang portion 82 is brought into contact with the second guide portion 66d. The engaged second position 104 is taken. In the second position 104, the overhanging portion 82 has moved to the third step portion 67 c that is one step lower than the first step portion 67 a in the first position 102, so that it does not return from the second position 104 to the first position 102. .

  Next, in the second state shown in FIG. 10C, the overhanging portion 82 moves to a third position 106 located at the lower end of the heart step portion 66a. In the second state, the overhang portion 82 may be detached from the heart cam mechanism 66.

  Next, in the third state shown in FIG. 10D, the overhanging portion 82 moves from the third position 106 along the third guiding portion 66e to the fourth position 108 and engages with the first guiding portion 66c. . At this time, since the overhanging portion 82 moves to the second step portion 67b that is one step lower than the fourth step portion 67d, the overhang portion 82 is configured not to return to the third position 106 after moving to the fourth position 108.

  Next, when returning from the third state to the first state, the overhanging portion 82 slides along the second stepped portion 67b and engages with the holding portion 66b. As described above, the overhang portion 82 relatively moves around the heart step portion 66a.

  13A shows the relationship between the hook 40, the first link 60 and the second link 70 in FIG. 10A, and FIG. 13B shows the hook 40 and the first link 60 in FIG. 10B. And the relationship of the 2nd link 70 is shown.

  When the hook 40 shown in FIG. 13A is in the first state, the arm 64 of the first link 60 is in contact with the protrusion 50 of the hook 40 and is in an engaged state. At this time, the first link 60 is urged in the first direction 85 by the first spring 84. Here, the second spring 90 attached to the hook 40 urges the hook 40 to rotate in the closing direction. However, since the urging force of the first spring 84 is stronger than the second spring 90, The rotation in the closing direction is suppressed. On the other hand, the first spring 84 biases the first link 60 so as to rotate in the first direction 85 against the second spring 90, but the rotation of the first link 60 is caused by the overhanging portion 82 and the holding portion 66 b. It is regulated by the engagement.

  When the hook 40 is pushed to the predetermined position in the closing direction from the first state shown in FIG. 13B, the overhanging portion 82 releases the engagement with the first link 60. That is, the overhanging portion 82 takes the second position 104 shown in FIG. 12 and is disengaged from the holding portion 66b. The first link 60 is rotated in the first direction 85 by the first spring 84 when the engagement is released, and the hook 40 to be engaged is rotated in the opening direction. When the first link 60 is stopped from rotating in the first direction 85 by the rotation restricting means, the hook 40 enters the second state.

  14A shows the relationship between the hook 40, the first link 60 and the second link 70 in FIG. 10C, and FIG. 14B shows the hook 40 and the first link 60 in FIG. 10D. And the relationship of the 2nd link 70 is shown.

  As shown in FIG. 14A, the bottom surface 32 of the case 20 functions as rotation restricting means, stops the rotation of the second link 70 and the first link 60, and enters the second state. The insertion / removal part 74 of the second link 70 abuts on the bottom surface 32 of the case 20, and the rotation of the insertion / removal part 68 in the first direction is stopped via the insertion / removal part 74. Note that the insertion / removal portion 68 of the first link 60 may be in direct contact with the bottom surface 32 to restrict the rotation and enter the second state. The rotation of the first link 60 may be stopped using the rotation restricting means other than the bottom surface 32 to be in the second state. Thus, the hook 40 can be automatically opened until it can be used.

  As shown in FIG. 14B, when the hook 40 is forcibly applied and rotated in the opening direction from the second state, the second link 70 rotates according to the rotation of the hook 40 to be engaged, and the hook 40 And the first link 60 are disengaged to rotate the first link 60 in the second direction opposite to the first direction. The hook 40 comes into contact with the frame of the case 20 and its rotation is restricted to enter the third state. When the hook 40 is in the third state, the overhanging portion 82 is engaged again with the first link 60 at the fourth position 108 shown in FIG.

  When the hook 40 is changed from the third state to the free state, the hook 40 is rotated in the closing direction by the second spring 90, the first link is rotated in the first direction by the first spring 84, and the projecting portion 82 is The relative movement from the fourth position 108 shown in FIG. 12 to the first position 102 causes the engagement of the first link 60 to restrict the rotation of the first link 60 again, and the hook 40 enters the first state. As a result, after the hook 40 is used, the hook 40 automatically closes and returns to the state before use when the object to be hooked is removed from the hook 40, so that the operation of closing the hook 40 can be omitted.

  FIG. 15 shows a hook 140 according to a modification. The hook 140 has an opening 142 formed at the center. Other configurations are the same. As a result, the hook 140 can be used by hanging a rope or the like.
