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

FIG. 9 is a perspective view of the entire construction showing the usage state of the gutter lid handling tool according to the first embodiment of the present invention.

Prior to use, the notch 10 in the gutter lid 100
The hook 50 that constitutes 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 disposed 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,
Hook member 21 of rod member 21 that constitutes vertical movement means 20
a is inserted so that the locking member 21a is not separated 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, and the straight line connecting the stopper support shaft 71 and the roller shaft 74 passes through a right angle at the intersection point 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 of the rotating member 72 is performed by the lever 75 by the support shaft 62. Since the hook 50 and the hook 60 are not rotated, the position of the hook 60 is restricted, and the hook 50 and the hook 60, which are in contact with both the notches 101 of the gutter lid 100, by their own elastic force. The side surfaces of the notches 101 are pressed. Also,
Bent end 51 of hook 50 and bent end 6 of hook 60
1 supports the back surfaces of both cutouts 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. Further, the small-diameter rotary handle 21b can relatively speed up the rotational force when the lifting of the gutter lid 100 requires a small force, and the workability thereof can be improved.

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 opposite direction to the lifting direction, the rod member 21 is lowered,
The gutter lid 100 can be spanned on both sides of the gutter. If the large-diameter rotary handle 22c is rotated in the opposite direction to when it is lifted, the rod 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 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 conveying member 40 side can be separated, and the gripping portions 41 arranged on both sides of the conveying member 40 can be carried for transportation.

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 rotating member 72 attached to a stopper support shaft 71 that 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 that supports the rotation member 72. In a gutter cover handling tool including a pressing member formed of a roller 73 that is rotated, 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 and 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 that presses 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 hooks 50 and 60 are expanded. This can be an embodiment of the invention of claim 1.

Therefore, the notch 101 of the gutter lid 100
The pair of hooks 50, 60 and the bent end portions 51, 61 bent inward to each other are inserted and applied, and then the lever 75 is rotated so that the pressing member resists the elastic force and the hooks. By rotating while pressing 60, the hooks 50, 60 are moved in a direction of narrowing each other, and the angle of intersection with the tangent line for pressing the hooks 50, 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 therewith is composed of its simple parts, and the grip portion 41 at both ends of the conveying member 40 is provided. Since the imbalance of the load applied to the conveyance member 40 does not occur, the conveyance member 40 does not give an unbalanced feeling to the person having the grip portions 41 at both ends.

The gutter lid handling tool of the above embodiment has the self-supporting frame means 10 having the vertical portion 11 which is erected vertically to the ground.
And bent end portions 51 and 6 in which the lower end portions are bent inward with respect to each other.

Then, a rotating member 72 attached to a stopper support shaft 71 that is fixed to a lever 75 and rotates to move the hook 60 against the elastic force applied to the hook 60. When the lever 75 is rotated, the shaft-supported pressing member rotates while pressing the hook 60 against the elastic force, and the hook 50, 60, so that the pressing members supported by the shafts are moved in a direction in which they are narrowed.
The rotation is stopped at a position where the angle of intersection with the tangent line for pressing passes through a right angle, and when the lever 75 is rotated in the opposite direction, the hook 60 receives elastic force and the hooks 50, 60. It is to move in the direction of expanding each other. This can be an embodiment of the invention of claim 2.

Therefore, the vertical portion 11 of the self-supporting frame means 10 formed in a substantially U shape is passed over to the side groove, so that the self-supporting frame means 10 can be obtained.

It consists of hooks 220 and 240 having 0a.

The carrying member 203 is in the shape of a pipe in a horizontal posture, a hanging metal fitting 204 which is curved and formed in an annular shape is fitted in the central portion, and is fixed by a pin 205 penetrating the carrying member 203. . Both ends of the hanging bracket 204 are
It is fastened together with a pin 206 on the conveying member 203, and the key type hook 202 of the rod member 21 is detachably hooked on the pin 206. And this key type hook 202
By releasing the lock of the conveying member 203, the conveying member 203 can be separated from the self-supporting frame means 10 as in the first embodiment.

Hook support fittings 207 and 208, which are curved in an inverted U-shape, engage with both ends of the carrying member 203 from above respectively, so that both hook support fittings 207 and 208 are provided.
Both end portions of the hooks face each other below the conveying member 203 at a predetermined interval to form a hook accommodating space 209. Further, the positioning hole 210 penetrating both hook support fittings 207, 208 selectively overlaps with any one of a pair of positioning holes 211, 212 penetrating along the conveying member 203 at intervals. Positioning shaft 21 that can be removed with pins etc.
3 is inserted. Therefore, both hook support fittings 2
07 and 208 are positioning holes 211 and 212 to be overlapped.
The position is changed along the conveying member 203 according to the above.

An inverted U-shaped accommodating groove 214 that opens downward is formed at both ends of the conveying member 203.
A base end of a bar-shaped grip portion 215 is provided in 14
Most of the grip portion 215 projects outward from the accommodation groove 214. At the base end of the grip 215, a long hole 21 is formed along the longitudinal direction.

As a result, as shown in FIG. 12, the grip portion 215 can be retracted laterally from the accommodation groove 214 within the range of the elongated hole 216. When the positioning shaft 213 is located on the right side in the elongated hole 216 at the time of the protrusion shown in FIG.
It is possible to switch between a horizontal grip position in contact with 4a and a storage position in which the grip position is rotated about the positioning shaft 213 downward by about 70 °. Further, when the gripping portion 215 is in the retracted position shown in FIG. The rotation to the position is restricted and the grip position is maintained.

As shown in FIGS. 11 and 13, the base end of the one hook 220 is disposed in the hook accommodating space 209 formed by the one hook supporting metal fitting 207, and the hook supporting metal fitting 207 is provided. It is rotatably attached by a support shaft 221 fixed to 207. This hook 220
Like the hook 60 of the first embodiment described above, is configured to be rotatable for holding the gutter lid 100, and there is a difference in the rotating mechanism.

The attachment state of the hook 220 will be described below. A spring 222 made of a wire is wound around the support shaft 221, and one end of the spring 222 has a hook support fitting 207.
Is hooked on a hooking piece 223 formed integrally with the hook 220, and the other end of the hooking piece 223 abuts on the intermediate upper part of the hook 220 to give an elastic force to rotate the hook 220 outward about the support shaft 221. . Then, the hook 220 at the normal time is the spring 222.
Is rotated outward by the urging force of the spring support member 207, and further rotation is restricted by a hooking piece 224 formed on the lower side of the hook support fitting 207. It leaves room to rotate inward.

The hook 220 of the hook support fitting 207
In the stopper support shaft 225 fixed to the outer side position,
An intermediate portion of a rotating member 226 having a substantially U-shaped cross section is rotatably attached, and the roller shaft 22 is attached to one end of the rotating member 226.
A roller 228 is rotatably fixed at 7 by a shaft. Further, a base end of a lever 229 is fixed to the other end of the rotating member 226, and the lever 229 is bent and formed, and is positioned on the side of the hook support fitting 207.

The turning of the turning member 226 about the stopper support shaft 225 in both directions is restricted by a pair of hooking pieces 230 and 231 formed integrally with the hook support fitting 207, respectively, as shown in FIG. As shown in FIG.
When the rotation of 26 is restricted by the upper hooking piece 230, the roller 228 on one end side of the rotation member 226 only abuts on the hook 220 and does not exert a force on the hook 220. . Further, as shown in FIG. 12, from this state, when the rotating member 226 rotates clockwise, the roller 228 rolls on the hook 220 to exert a pressing force and resist the urging force of the spring 222. While supporting shaft 22
The hook 220 is rotated inward about the position 1. Then, as in the case of the first embodiment, the stopper support shaft 2
25 and the roller shaft 227, and the intersection point angle of the roller 228 and the tangent line that presses the hook 220 have passed a right angle, the hook 220 is a hooking piece formed below the hook support fitting 207. Abuts 232.

Further, the rotating member 2 of the hook support fitting 207
A regulating shaft 233 is fixed to a position outside the position 26, a base end of a return regulating pawl 234 is rotatably attached to the regulating shaft 233, and a tip of the return regulating pawl 234 hangs down.
It is formed in a key shape protruding outward. Return restriction claw 2
An operation piece 235 is bent at a right angle in the middle of 34,
The operation piece 235 projects laterally through a square operation hole 236 formed in the hook support fitting 207.
Therefore, the rotation of the return restricting claw 234 is restricted to a predetermined range by the operation hole 236, and the return restricting claw 234 can be rotated by manually operating the operation piece 235. A spring 237 made of a wire is wound around the regulation shaft 233, one end of the spring 237 is hooked on the operation piece 235 of the return regulation claw 234, and the other end thereof regulates the rotation of the rotating member 226. It is hooked on the hooking piece 230 and gives an elastic force to rotate the return restricting claw 234 outwardly about the restricting shaft 233.

Then, as shown in FIG. 11, when the rotating member 226, which is in contact with the upper hooking piece 230, is rotated clockwise by the operation of the lever 229, the lever 22 is rotated.
As the basal end of 9 moves upward, as shown by the phantom line in FIG. 12, the tip of the return restricting claw 234 is pressed to rotate slightly inward, and the rotating member 226 causes the lower restricting piece 231 to move. When the rotation is restricted by, the base end of the lever 229 is
The rotation of the rotation member 226 in the reverse direction is complemented by the return regulation claw 234 that has returned to the original position by the urging force of 37, that is,
The return of the hook 220 to the outside is restricted. Also,
In this state, when the operation piece 235 of the return regulating claw 234 is pressed inward, the return regulating claw 234 slightly rotates inward against the biasing force of the spring 237 and rotates with respect to the rotating member 226. Restrictions are lifted.

On the other hand, as shown in FIG. 10, the hook accommodating space 20 formed by the other hook support fitting 208 is formed.
The base end of the other hook 240 is disposed inside the hook 9. The hook 240 is non-rotatably fixed similarly to the hook 50 of the first embodiment described above, and the mounting state thereof is completely the same as that of the hook 50, and therefore detailed description thereof will be omitted.

Next, a procedure for using the gutter lid handling tool configured as described above will be described. Since the basic procedure of use is the same as that of the first embodiment, differences will be mainly described.

First, in the gutter cover handling tool for transportation to the site, as shown in FIGS. 10 and 11, the grip portion 215 is switched to the storage position. Therefore, the transport member 2
Since the total length of 03 is shortened, the grip 215 does not hinder the transportation, and it can be easily transported. Then, when the grip portion 215 is rotated to the grip position and is retracted into the accommodation groove 214 at the site, as shown in FIG. 12, the proximal end of the grip portion 215 has an upper wall 214 inside the accommodation groove 214.
It comes into contact with a and is restrained from rotating to the storage position by its own weight, that is, downward rotation, and is held at the gripping position to complete the preparation.

Then, similarly to the first embodiment, first,
As shown in FIG. 11, the lever 229 is rotated counterclockwise to bring the rotating member 226 into contact with the upper hooking piece 230, and the hook 220 is supported by the elastic force of the spring 222. The position is such that the shaft 221 is pivoted outward about the axis 221. Therefore, the distance between the hook 220 and the hook 240 becomes maximum. In addition, the leg members 1 on both sides of the self-supporting frame means 10
3 and the rotating leg member 14 are arranged outside the gutter lid 100 on both sides of the gutter so as not to step on the gutter lid 100.
1, the bent end 220 of the hook 220 of the transport member 203
a and the bent end portion 240a of the hook 240 are respectively inserted.

The bent end 220a and the bent end 2
When the lever 40a reaches the rear surface of the gutter lid 100 and the lever 229 is rotated clockwise as shown in FIG.
While the roller 228 rolls on the hook 220 to exert a pressing force against the biasing force of the spring 222,
The hook 220 is rotated inward around 21. As a result, similar to the case of the first embodiment, the straight line connecting the stopper support shaft 225 and the roller shaft 227 and the roller 22
8 is at a position where the angle of intersection with the tangent line pressing the hook 220 has passed a right angle, the hook 220 is fixed to the hook support fitting 20.
7 is brought into contact with a hooking piece 232 formed on the lower side of the hook 7,
20 and the hook 240 are self-elastic, and the gutter lid 100 is
While pressing the side surfaces of both the notches 101, the notches 10 at the bent end 220a and the bent end 240a at the tip.
The back side of 1 is supported.

In the gutter cover handling tool of this embodiment, when the lever 229 is rotated, the base end of the lever 229 moves upward as the rotary member 226 rotates clockwise, and the lever 229 moves upward. The tip end of the return restricting claw 234 is pressed by the base end of the spring 229, and as shown by the phantom line in FIG.
It slightly rotates inward against the biasing force of. Then, when the rotation of the rotating member 226 is restricted by the lower restricting piece 231, the base end of the lever 229 is complemented by the return restricting claw 234 that has returned to its original position by the biasing force of the spring 237. .
Therefore, even when the tilt lever 229 is rotated counterclockwise, the rotation of the rotation member 234 is returned, that is,
The return of the hook 220 to the outside is restricted, and the hook 2
The gutter lid 100 is reliably held by the hook 20 and the hook 240.

Then, like the first embodiment, when the large-diameter rotary handle 22c is rotated, or when the large-diameter rotary handle 22c is fixed with one hand and the small-diameter rotary handle 21b is rotated. The conveying member 203 as well as the rod member 21 is lifted to lift the gutter lid 100. After that, when the gutter lid 100 is moved to another place, the grips 215 that have been switched to the grip positions at both ends of the transport member 203 are gripped and lifted to support the entire weight of the transport member 203 and the gutter lid 100. Above, the key type hook 202 at the lower end of the bar member 21 is attached to the hanging metal member 204 of the conveying member 203.
Can be detached from the pin 206, the transport member 203 side can be separated from the self-supporting frame means 10, and can be moved to any place.

On the other hand, when the gutter lid 100 lifted as described above is returned to the gutter, the small-diameter rotary handle 21b is used.
Is reversed to lower the gutter lid 100 together with the conveying member 203 into the gutter. Then, when the operation piece 235 of the return regulating claw 234 is pressed inward after landing of the gutter lid 100, the return regulating claw 234 slightly resists the urging force of the spring 237 as shown by a virtual line in FIG. Swivel inward,
In this state, when the lever 229 is rotated counterclockwise as shown in FIG. 11, the rotation member 234 causes the rotation member 226 to roll the roller 228 on the hook 220. While rotating, rotate counterclockwise,
It abuts on the upper retaining piece 230. Therefore, the spring 22
The hook 220 is rotated outward by the biasing force of
Both notches 10 of the side groove 100 by the 20 and the hook 240
1 is stopped, and the bent end 220
The support of the back surfaces of the notches 101 by the a and the bent end 240a is stopped, and as a result, the bent end 220a and the bent end 240a can be separated from the notches 101.

When the gutter lid handling tool is to be transported to another place after the operation of the gutter lid 100 is completed, both grip portions 21 of the transport member 203 which has been switched to the grip position.
5 is operated to project and rotated downward. Therefore, as shown in FIG. 12, both grips 215 are switched to the retracted position again, the entire length of the transport member 203 is shortened, and the grips 215 do not hinder the transportation, so that they can be easily transported. it can.

Thus, the gutter lid handling tool of this embodiment is
A pair of hooks 220 having a conveying member 203 having grips 215 at both ends, and a pair of bent ends 220a and 240a formed by bending the lower ends of the conveying members 203 inward.
240, an elastic member 222 that applies an elastic force to the hook 220 in a predetermined direction, and a stopper that is fixed to a lever 229 and rotates to move the hook 220 against the elastic force applied to the hook 220. A rotating member 226 attached to the support shaft 225, a pressing member including a roller 228 supported by a roller shaft 227, and the hook 2.
When the lever 229 is rotated in a gutter lid handling tool that is provided with a return regulation claw 234 that regulates the rotation return of the rotation member 226 after the movement of 20 and that can release the regulation manually. , The pivotally supported pressing member rotates while pressing the hook 220 against the elastic force, and moves in a direction of narrowing the space between the hooks 220 and 240, and the pivotally supported pressing member causes the hook 220 to move. The rotation is stopped at a position where the angle of intersection with the tangent line that presses 220 passes through a right angle, and the return restricting claw 234 restricts the return of the pressing member from rotating, and the return restricting claw 234 is restricted. When the lever 229 is rotated in the opposite direction by manually releasing the hook 220, the hook 220 receives an elastic force and moves in a direction in which the hooks 220 and 240 expand. This can be an embodiment of the invention of claim 3.

Therefore, the notch 101 of the gutter lid 100
The bent ends 220a, 240 of the hooks 220, 240
When a is inserted and applied and the lever 229 is rotated, the pressing member moves in a direction of narrowing the space between the hooks 220 and 240 with the rotation, and the angle of intersection with the tangent line with which the pressing member presses the hook 220 is changed. Since the rotation is stopped at a position where it passes a right angle, the reverse rotation power does not act on the pressing member,
The gutter lid 100 does not separate from the hooks 220 and 240. Moreover, since the return restriction claw 234 restricts the rotation return of the pressing member, even if the lever 229 is accidentally rotated by mistake, the hook 220 and the hook 240 are not moved.
Thus, the gutter lid 100 continues to be reliably held, and the gutter lid 100 does not separate from the hooks 220 and 240 during transportation and does not drop.

Further, in the gutter lid handling tool of this embodiment, the conveying member 203 having grips 215 at both ends thereof and the bent end portion 2 in which the lower end portions of the conveying member 203 are bent inward with respect to each other.
A pair of hooks 220 and 240 having 20a and 240a
An elastic member 222 for applying an elastic force in a predetermined direction to the hook 220, and a stopper support that is fixed to a lever 229 and rotates to move the hook 220 against the elastic force applied to the hook 220. In the gutter lid handling tool provided with the rotating member 226 attached to the shaft 225 and the pressing member composed of the roller 228 pivotally supported by the roller shaft 227, the grip portions 215 can be retracted at both ends of the conveying member 203. , And is rotatably connected between the grip position and the retracted position about the base end, allows the pivot to the retracted position when the grip 215 projects, and moves the retracted position to the retracted position when the grip 215 is retracted. A gripping part restricting part formed of an upper wall 214a in the accommodation groove 214 for restricting rotation is provided. This can be an embodiment of the invention of claim 4.

Therefore, when the grip portion 215 is rotated to the grip position and is retracted into the accommodation groove 214, the grip portion 215 is moved.
Is held at the gripping position by restricting its rotation to the storage position by the gripping part regulating part, and for example, when the gutter lid 100 held by the hooks 220 and 240 is moved to another place, The fixed grip portion 4 of the gutter lid handling tool described in the embodiment.
As in the case of 1, the gutter lid 100 can be moved without any trouble while gripping the grip portion 215. In addition, by switching the grip portion 215 to the storage position during the transportation of the gutter lid handling tool, the entire length of the transport member 203 is shortened, and the grip portion 215 does not hinder the transportation, so that it can be easily transported. Moreover, the area occupying the space can be reduced during storage.

[0072]

As described above, in the gutter lid handling tool of the invention of claim 1, a pair of hooks are inserted into both notches of the gutter lid,
Then, the lever is rotated to move the hooks in a direction of narrowing each other, and the rotation is stopped at a position where the angle of intersection with the tangent line pressing the hook by the pivotally supported pressing member has passed a right angle. Let Even if the gutter lid is clamped by using the elastic force of the hook, the elastic force does not act as a reverse rotation force via the pressing member, and the elastic force is transmitted to the stopped member side. The gutter lid will not separate from the hook unless the hook is released by rotating the lever.
Therefore, two people can hold the grips at both ends of the carrying member and can carry it to a predetermined destination, and the gutter lid will not separate from the hook and fall during the carrying.

Further, an elastic member for applying an elastic force to the hook in a predetermined direction, and a pressing member fixed to a lever and rotating to move the hook against the elastic force applied to the hook, Since it is composed of such simple parts and does not cause an imbalance in the load applied to the grips at both ends of the carrying member, the carrying member has a feeling of imbalance in weight for a person having grips at both ends. I can't let it go.

According to another aspect of the present invention, there is provided a gutter cover handling tool, in which the vertical portion of the self-standing frame means formed in a substantially U-shape is transferred to the side groove, and the vertical moving means of the vertical moving means is attached to the substantially central portion of the self-standing frame means. By rotating the rotating member, the rod member moves up and down, and lifts the conveying member engaged with the lower end portion of the rod member and the gutter lid supported by the bent end portion of the hook of the conveying member. At this time, the rotation member of the vertical moving means and the rod member are screwed to each other by screw connection, and the pitch that changes in the vertical direction by the rotation of the rotation member can be selected. Things can be displaced. Further, when the engaging state of the conveying member engaged with the lower end portion of the bar member of the vertical moving means is released, the vertical moving means and the transfer means are separated, and both grip portions of the conveying member constituting the transfer means are held. By moving, the gutter lid can be moved to a predetermined position.

Since the self-standing frame means and the vertical moving means, which are formed in a substantially U shape, and the transfer means can be separated from each other, they can be stored separately when stored, and the area occupying the space can be reduced. .

In the gutter cover handling tool of the third aspect of the present invention, a pair of hooks are inserted into both notch portions of the gutter cover, and the lever is rotated to move the hooks in a direction in which they are narrowed.
The rotation of the pressing member supported by the shaft is stopped at a position where the angle of intersection with the tangent line for pressing the hook passes a right angle, and the return restricting member restricts the return of the pressing member.
As a result, even if the lever is accidentally rotated, the gutter lid does not separate from the hook unless the regulation of the return regulating member is released. Therefore, two people can hold the grips at both ends of the carrying member and can carry it to a predetermined destination, and the gutter lid will not separate from the hook and fall during the carrying.

In the gutter cover handling tool of the fourth aspect of the present invention, when the grip portion is rotated to the grip position and the immersing operation is performed, the grip portion is held at the grip position, and while gripping the grip portion, there is no problem. It is possible to move the gutter lid, and if the grip is switched to the storage position during transportation of the gutter lid handling tool, the total length of the transport member will be shortened and the grip will not hinder the transport, making it easy to transport. It becomes possible, and at the time of storage, the area occupying the space is reduced.
