The gutter lid handling tool configured as described above is used as shown in FIG.

FIG. 9 is a perspective view showing the entire construction of a gutter lid handling tool according to an embodiment of the present invention in use.

Prior to use, the notch 10 in the gutter lid 100
The hook 50 constituting the transfer means 30 according to the interval of 1
The attachment positions of the hook shaft 52 and the movement restraining shaft 54 are set to the hook shaft holes 55a and 55b or the movement restraining shaft holes 56a and 56.
Any position of b.

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.

When the large-diameter rotary handle 22c constituting the vertical moving means 20 is rotated in this state, 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,
The rod member 21 can also be raised by fixing the large-diameter rotary handle 22c constituting the vertical moving means 20 with one hand and rotating the small-diameter rotary handle 21b. Even if a large force is required to lift the gutter lid 100, the rotational force of the large-diameter rotary handle 22c can be dealt with by 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 lifting of the entire 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.

Further, when it is necessary to move the gutter lid 100 to another place, when the lifting of the entire gutter lid 100 is completed and the gutter lid 100 is completely separated from the gutter lid, the grip portion 41 provided on the conveying member 40 is removed. By lifting both sides and rotating the small-diameter rotary handle 21b, or by rotating the lifted conveying member 40 side, the latching member 21a is disengaged from the fitting portion 43, and the conveying member 40 is inserted and removed through 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
Vertically stand both sides with respect to the ground to form a vertical portion 11,
The self-supporting frame means 10 formed in a substantially U-shape, the rod member 21 having a male screw formed to move vertically in the vertical direction, and the male screw of the rod member 21 are screwed together, and the self-supporting frame means 10 is also provided. Of the vertical moving means 20, which is attached to a substantially central portion of the vertical moving means 20 and has a rotating member 22 which rotates in a screw-engaged state with the male screw. In addition, the transport member 40 having the grip portions 41 on both sides
And a pair of hooks 5 for supporting the gutter lid 100, which is located in the inner lower portions of both the grip portions 41 of the transport member 40 and is bent so that the end portions face each other, and one of which is movable.
And a transfer means having 0 and 60.
This can be an embodiment of the invention of claim 1.

Therefore, the vertical portion 11 of the self-supporting frame means 10 formed in a substantially U shape is passed to the side groove, and the self-supporting frame means 10 is provided.
By rotating the rotating member 22 of the vertical moving means 20 attached to the substantially central portion of the, the rod member 21 moves up and down,
The transport member 40 engaged with the lower end of the rod member 21, and the bent ends 51, 61 of the hooks 50, 60 of the transport member 40.
Lift the gutter lid supported by. At this time, according to the product implemented by the inventors, the gutter lid 100 could be lifted even if a load of several tons was applied to the gutter lid 100. That is, the rotation member 22 of the vertical moving means 20 and the rod member 21 are screwed together,
Since it is displaced at a specified pitch by screw connection, one rotation of the rotating member 22 causes a vertical change of about 1 cm, and a large load specified by rotating the rotating member 22 is displaced. Can be made

In this state, while the rotation of the small-diameter rotary handle 21b is stopped, the transport member 40 is rotated by approximately 90 degrees, and the transport member 40 engaged with the lower end portion of the rod member 21 of the vertical moving means 20. When the engagement state of (1) is released, the vertical moving means 20 and the transfer means 30 are separated, and by moving by holding both grip portions 41 of the transfer member 40 constituting the transfer means 30,
The gutter lid can be moved to a predetermined position.

Further, the self-supporting frame means 1 formed in a substantially U shape.

Since the self-supporting frame means 10, the vertical moving means 20 and the transfer means 30 can be separated from each other by including the transfer means 30 having the above, the separate storage can be performed at the time of storage and the area occupying the space can be reduced. ..

Then, the self-supporting frame means 1 formed in a substantially U-shape having vertical portions 11 vertically standing on both sides of this embodiment.
No. 0 has a leg member 13 which is rotatable at a predetermined angle at one end of one vertical part 11 and makes two-dimensional or more contact with the ground, and the other end of the vertical part 11 is substantially The self-supporting frame means 10 is provided since the rotatable leg member 14 is arranged to make contact with the ground by the cross-sectional area of the end of the vertical portion.
Even when it is difficult to obtain the set position of the vertical portion 11 or when the unevenness of the set position of the vertical portion 11 is severe, the sharing of the force can be made uniform and a stable installation state can be achieved. Since the leg member 13 that makes two-dimensional or more contact with the ground can be rotated and positioned at a location on the ground with good conditions, it is difficult to be restrained by the unevenness of the positioning and installation conditions. Further, since the leg member 13 that makes two-dimensional or more contact with the ground can alleviate the load distribution, the softness of the ground does not pose a problem and stable installation is possible.
This can be an embodiment of the invention of claim 2.

Furthermore, since the leg member 13 which makes contact with the ground surface in two or more dimensions is rotatable by a predetermined angle, it is easy to move the pivot about the leg member 13. In particular, since the rotatable pivoting leg member 14 disposed at the end of the opposite vertical portion 11 can rotate 360 degrees, it is possible to move the pivot about the vertical portion 11.

Furthermore, the hooks 50 and 60 for supporting the movable gutter lid 100 of this embodiment are the hooks 5 described above.

When the lever is rotated, the pressing member supported by the shaft resists elastic force. The hook 50, 60 is rotated while being pressed, and is moved in a direction in which the space between the hooks 50, 60 is narrowed, and a pressing member pivotally supported by the stopper support shaft 71 forms a tangent line for pressing the hook 50, 60. The rotation is stopped at a position where the intersection angle of the two passes through a right angle, and when the lever 75 is rotated in the opposite direction, the hooks 50 and 60 receive an elastic force, and the hooks 50 and 60 are separated from each other. It is to move in the unfolding direction.

Therefore, since the hooks 50 and 60 for supporting the gutter lid 100 are held by using the elastic force of the hooks 50 and 60, the held gutter lid 100 does not drop due to vibration or the like. .. Particularly, when the lever is rotated, the axially supported pressing member rotates while pressing the hooks 50 and 60 against the elastic force, and the hook 5
The pressing members pivotally supported by the stopper support shaft 71 move the hooks 50, 6 by moving them in a direction of narrowing the space between them.
Since the rotation is stopped at a position where the angle of intersection with the tangent line that presses 0 passes through a right angle, the gripping state cannot be released unless the lever is operated. Therefore, it is inadvertently released during transportation of the gutter lid 100. Never be done.

As described above, in the gutter cover handling tool according to the invention of claim 1, the vertical portion of the self-standing frame means formed in a substantially U-shape is passed to the side groove, and is provided at the substantially central portion of the self-standing frame means. By rotating the rotating member of the attached vertical moving means, the rod member 21 moves up and down, and the conveying member engaged with the lower end portion of the rod member,
Also, the gutter lid supported by the bent end of the hook of the conveying member 40 is lifted. Further, in this state, if the engaging state of the conveying member engaged with the lower end portion of the rod member of the vertical moving means is released, the vertical moving means and the transfer means are separated, and the conveying member constituting the transfer means is separated. By moving with holding both grips, the gutter lid can be moved to a predetermined position.

Then, a vertical moving means having a self-standing frame means formed in a substantially U-shape, a rotating member attached to a substantially central portion of the self-standing frame means, and a lower end portion of a bar member of the vertical moving means. And a transfer means having a transfer member detachably engaged with each other, and the self-standing frame means, the vertical movement means, and the transfer means can be separated from each other. The occupied area can be reduced.

According to a second aspect of the present invention, there is provided a gutter lid handling tool having a leg member which makes two-dimensional or more contact with the ground which is rotatable by a predetermined angle at one end of one vertical portion of the self-supporting frame means. It is arranged. Therefore, when it is difficult to obtain the setting position of the vertical portion of the self-supporting frame means, or when the vertical position of the self-supporting frame means is highly uneven, the sharing of the force can be made uniform and a stable installation state can be achieved. Since the leg member that makes two-dimensional or more contact with the ground can be rotated and positioned to a location on the ground with good conditions, it is difficult to be restrained by the unevenness of the positioning and installation conditions, and the load distribution can be relaxed. ..

In the gutter cover handling tool according to the third aspect of the present invention, when the lever is rotated, the axially supported pressing member rotates while pressing the hook against the elastic force to narrow the space between the hooks. The rotation is stopped at a position where the angle of intersection with the tangent line that presses the hook passes past a right angle, and the lever is rotated in the opposite direction. Since the hooks receive the elastic force and move in a direction in which the hooks are spread apart from each other, the gutter lid held by the elastic force of the hooks does not drop due to vibration or the like. Particularly, when the lever is rotated, the pivotally supported pressing member pivots while pressing the hooks against the elastic force to move the hooks in a direction of narrowing them, and the stopper support shafts support the shafts. Since the rotation of the pressing member is stopped at a position where the intersection angle with the tangent line that presses the hook passes through a right angle, the gripping state is not released unless the lever is operated, and careless during transportation. The gutter lid does not fall into the.
