First, the lever 75 constituting the transfer means 30.
Is the position where the rightward rotation due to the notch of the transport member 40 is restricted, and the hook 60 is the position of the chain double-dashed line that is rotated outward about the support shaft 62 by the elastic force of the leaf spring 63. The bent end portion 61 is opened to the maximum to widen the pivotable width. Further, the self-supporting frame means 1 formed in a substantially U shape
The leg member 13 disposed at one lower end of the vertical portion 11 in which both sides of 0 are erected vertically and the rotating leg member 14 disposed at the other lower end are placed on both sides of the gutter, and the gutter lid 100 is stepped on. Not placed outside. At this time, in the insertion / removal hole 42 of the transport member 40,
Hooking member 21 of rod member 21 that constitutes vertical moving means 20
a is inserted so that the locking member 21a does not separate from the fitting portion 43.

Then, the bent ends 51 of the hooks 50 and the bent ends 61 of the hooks 60 of the conveying member 40 constituting the transfer means 30 are inserted into both the notches 101 of the gutter lid 100.
When the bent end portion 51 and the bent end portion 61 reach the back surface of the gutter lid 100, the lever 75 is rotated to a position where it abuts on the support shaft 62. As a result, the roller 73 presses the surface of the hook 60 while rotating it, and the straight line connecting the stopper support shaft 71 and the roller shaft 74 passes through a right angle at the intersection with the tangent line with which the roller 73 presses the hook 60. The position.
At this time, the hook 60 is biased by the elastic force of the leaf spring 63 so as to rotate outwardly around the support shaft 62, but the rotation member 72 is rotated by the lever 75 by the support shaft 62. Since it does not rotate, the position of the hook 60 is regulated, and the hook 50 and the hook 60, which are in contact with both the notches 101 of the gutter lid 100, are elastic by their own elastic force. The side surfaces of both cutouts 101 are pressed. Also,
Bent end 51 of hook 50 and bent end 6 of hook 60
1 supports the back surfaces of both notches 101 of the gutter lid 100.

In this state, with the rotation of the small-diameter rotary handle 21b stopped, the conveying member 40 is rotated by approximately 90 degrees, and the large-diameter rotary handle 22 constituting the vertical moving means 20 is rotated.
When c is rotated, the rotation of the rod member 21 screwed with the large-diameter rotary handle 22c is restricted,
The rod member 21 moves up. Of course, by fixing the large-diameter rotary handle 22c that constitutes the vertical moving means 20 with one hand,
Even if the small-diameter rotary handle 21b is rotated, the rod member 2
You can raise 1. Large diameter rotating handle 22c
Even if a large force is required to lift the gutter lid 100, the rotational force of can be handled with a relatively small force. Also, the small-diameter rotary handle 21b can relatively speed up the rotational force when lifting the gutter lid 100 with a small force, and can improve the workability thereof.

When the entire lifting of the gutter lid 100 is completed and the gutter lid 100 is completely separated from the gutter, the grips 41 arranged on both sides of the conveying member 40 constituting the transfer means 30 are rotated in a specific direction. For example, after rotating the transport member 40 by 90 degrees,
When the large-diameter rotary handle 22c is fixed with one hand and the small-diameter rotary handle 21b constituting the transfer means 30 is rotated in the direction opposite to the lifting direction, the rod member 21 is lowered,
The gutter lid 100 can be stretched over both sides of the gutter. If the large-diameter rotary handle 22c is rotated in the opposite direction to when it is lifted, the bar member 21 is lowered and can be lowered similarly to the rotation of the small-diameter rotary handle 21b.

When it is necessary to move the gutter lid 100 to another place, when the entire gutter lid 100 is completely lifted and is completely separated from the gutter, the grip portion 41 provided on the conveying member 40 is moved. By lifting both sides and rotating the small-diameter rotary handle 21b, or by rotating the lifted conveying member 40 side, the hooking member 21a is disengaged from the fitting portion 43, and the conveying member 40 is inserted and removed from the insertion hole 42. The hooking member 21a of the rod member 21 can be extracted, the side of the conveying member 40 can be separated, and the gripping portions 41 arranged on both sides of the conveying member 40 can be carried to carry.

In this way, the gutter lid handling tool of this embodiment is
A conveying member 40 having grips 41 at both ends, and a bent end portion 5 in which the lower ends of the conveying member 40 are bent inward with respect to each other.
A pair of hooks 50, 60 having 1, 61, and an elastic member 63 for applying an elastic force to the hook 60 in a predetermined direction,
A rotation member 72 attached to a stopper support shaft 71 which is fixed to a lever 75 and rotates to move the hook 60 against the elastic force applied to the hook 60, and a roller shaft 74 supports the rotation member 72. In a gutter lid handling tool including a pressing member formed of a roller 73, when the lever 75 is rotated, the shaft-supported pressing member rotates while pressing the hook 60 against an elastic force. And the hook 5
0, 60 are moved in a direction of narrowing each other, and the rotation is stopped at a position where the angle of intersection of the rotatably supported pressing member and the tangent line for pressing the hook 60 passes a right angle, and in the opposite direction. When the lever is rotated, the hook 60 receives an elastic force and moves in a direction in which the space between the hooks 50 and 60 is expanded.

By rotating while pressing 60, the hooks 50 and 60 are moved in a direction of narrowing each other, and the angle of intersection with the tangent line for pressing the hooks 50 and 60 by the pivotally supported pressing member passes through a right angle. Since the rotation is stopped at the excessive position, even if the gutter cover 100 is clamped by using the elastic force of the hook 60, the elastic force does not act as a reverse rotation force via the pressing member and is stopped. The elastic force is transmitted to the member side, and most of it is transmitted to the rotating member 72 attached to the stopper support shaft 71. Therefore, unless the lever 75 is rotated to release the hook 60, the gutter cover is released. 100 is the hook 50, 60 It is not to leave. Therefore, two persons can hold the grips 41 at both ends of the transport member 40 and can transport the grips 41 to a predetermined destination, and the gutter lid 100 does not separate from the hooks 50 and 60 and fall during the transportation.

Further, an elastic member 63 for applying an elastic force in a predetermined direction to the hook 60 and a lever 75 are fixed and rotated to move the hook 60 against the elastic force applied to the hook 60. The pressing member composed of the rotating member 72 attached to the stopper support shaft 71 and the roller 73 pivotally supported by the roller shaft 74 on the pressing member is composed of its simple parts, and the grip portions 41 at both ends of the conveying member 40 are provided. Since the imbalance of the load applied to the carrier does not occur, the carrying member 40 does not give a feeling of imbalance to the person having the grips 41 at both ends.
