By changing the combination of the notches 4c, the notches 33, 3
The length between both holding plates 13, 13 can be increased to match the length between the three.

On the other hand, the lever wheel 3 corresponds to a lever mechanism in the present invention, and as shown in FIG. 1, elongate lever rods 21 and 21 each having a handle 26 at the ends 22b and 22b, Support legs 23, 23 extending downward are provided at positions near the ends 22a, 22a of the lever bars 21, 21. L-shaped fittings 2 for engaging and holding the holding tools 2 are provided on both ends 22a, 22a of the lever rods 21, 21.
5, 25 are attached. In addition, both support legs 2
Wheels 24, 24 are attached to lower ends of the wheels 3, 23, respectively. In this case, the lever 21 is made of wood, metal,
It is formed of a synthetic resin material or a rigid member obtained by combining them with a length of about 90 cm. In the present embodiment, two timbers (wooden) are connected so as to be parallel to each other with an interval of about 30 cm, and the support legs 23 are extended from the end 22a to a position of about 30 cm.

Next, a method of using the detaching device 1 will be described with reference to the drawings.

In the detaching apparatus 1, when the lid 32 is removed relatively lightly, or when the lid 32 is removed in a place where there is not enough space to use the lever 3, the holding tool 2 is used.
And the lid 32 is detached using the hanging string 4 or the handle bar. Specifically, first, when mud or sand is clogged between the lids 32, it is possible to always remove the shaft member 15, but it is possible to remove the shaft member 15 and separate the arms 11a from each other. The end 12b of (or 11b) is inserted between the lids 32, 32 to scrape out foreign matter. Next, if necessary, in order to facilitate the subsequent lifting of the lid 32, the end 12b of the arm 11a (or 11b) is inserted into the water collecting hole 34 and the end 12a is pushed down to close the lid 32. Loosen 32. Next, when the shaft member 15 has been removed, the shaft insertion holes 14b,
The shaft member 15 is inserted through 14b, and the beta pin 16 is inserted into the hole of the shaft member 15. Next, both ends of the suspension string 4 are inserted into the insertion holes 18 of the arms 11a and 11b, respectively, and fixed. Subsequently, the holding plates 13, 13 are inserted into the water collecting holes 34, 34 between the lids 32, 32,. Next, the middle part of the hanging string 4 is hung on the shoulder and pulled up in the direction of arrow A shown in FIG. At this time, as shown in FIG. 5, both arms 11a, 11b
The end portions 12b, 12b of the
As a result, the end portions 12a, 12a rotate in the directions of arrows C1, C2. As a result, the holding plates 13 and 13 move relative to the lid 32 in the directions of the arrows D1 and D2, and hold the cutout portions 33 and 33 of the lid 32 on the surface on which the notches 33 and 33 are formed.

Next, when the hanging string 4 is further pulled up,
Barbs 17, 17 engage the bottom edge of lid 32. As a result, the lid 32 is supported by the barbs 17 and 17 while being held by the holding plates 13 and 13 and moves upward in the direction of arrow A. In this case, since the barbs 17, 17 are brought into contact with the bottom edge of the lid 32 so as to pierce them, it is possible to reliably prevent the lid 32 from falling off in the sandwiched state. Further, in a state where the lid 32 is clamped, a force for moving the clamping plates 13, 13 in the directions of the arrows D1 and D2 is also generated by the weight of the lid 32, and the barbs 17 reliably support the lid 32. Therefore, unlike the conventional attachment / detachment device 51, the lid 32 can be reliably prevented from falling off at the time of lifting without applying a force in the direction of clamping the lid 32. Thereafter, the lid 32 held by the holding tool 2 is carried to a predetermined place, and placed on, for example, the sleepers SP.
Thereby, the removal of the lid 32 is completed. Meanwhile, lid 3
At the time of attachment to the side groove 31, the lid 32 is carried using the holding tool 2 and the hanging string 4, and the holding tool 2 is moved downward. Thereby, the lid 32 automatically fits into the side groove 31 by its own weight. In this state, since the lid 32 is supported by the side groove 31, the holding by the holding plates 13, 13 is automatically released. If the lid 32 is light,
Using one arm 11a (or 11b), the lid 32
Can also be raised. In this case, first, a handle bar is inserted into the insertion hole 18 of the arm 11a. Next, the barb 17 of the holding plate 13 is hooked on the edge of the notch 33 of the lid 32, and in this state, the handle bar is pulled up with both hands, whereby the notch 33 side of the lid 32 can be pulled up. .

On the other hand, the relatively heavy lid 32 is removed,
When removing the lid 32 at a place where the use space of the lever wheel 3 can be secured, the lid 32 is attached and detached by using the holding tool 2 and the lever wheel 3. In this case, first, the water collecting hole 3
The holding plates 13, 13 of the holding tool 2 are inserted into the holding members 4, 34. Next, as shown in FIG. 6, the handle portion 26 is lifted upward,
The arms 11a, 11 are connected to the L-shaped brackets 25, 25 of the lever 3
The ends 12b, 12b of b are hooked. Next, the grip portion 26 is pushed down in the direction of arrow E. In this case,
When the lever bar 21 rotates with the wheel 24 as a fulcrum, the holding tool 2 that is hooked on the L-shaped bracket 25 is lifted in the direction of arrow F. In this case, the arms 11a, 1
As a result of the rotation of the ends 12b of the first member 1b around the shaft member 15 in the directions of arrows B1 and B2 shown in FIG.
Is turned back while being held by the holding plates 13, 13.
It is supported by 7, 17 and moves upward in the direction of arrow A.
Thereby, the lid 32 is removed from the side groove 31 as shown in FIG.

In this case, since the support leg 23 of the lever wheel 3 is attached to the end portion 22a of the lever rod 21 in the detachable device 1, the support leg 23 (that is, the wheel 24) is supported by the principle of leverage. The handle portion 26 acts as a point of force, and the L-shaped bracket 25 acts as a point of action, and a force acts on the clamp 2. Therefore,
The lid 32 can be lifted with an extremely small force of about 1/3 as compared with the case where the lid 32 is directly lifted using the hanging string 4. In addition, since the weight can be lifted by applying weight to the handle portion 26, even a weak woman or a person with low back pain can easily lift the heavy lid 32. Thereafter, the lever wheel 3 is moved while the lid 32 is suspended via the holding tool 2, and placed on, for example, the sleepers SP. At this time, since the wheels 24 are attached to the support legs 23, the lifted lid 32 can be moved very easily. On the other hand, when attaching the lid 32 to the side groove 31, the handle 32 is lifted upward after the detachment device 1 is moved, so that the lid 32
Automatically get stuck.

On the other hand, for example, as shown in FIG. 9, when attaching and detaching the lid 36 in which the notches 37, 37 are formed in a tapered shape, the interval between the holding plates 13, 13 is slightly longer than that of the lid 32. In order to make the shaft insertion holes 14 of the arms 11a and 11b
a, the shaft member 15 is inserted through 14a. Next, the holding plates 13, 13 are inserted into water collecting holes formed by the cutout portions 37, 37 of the adjacent lids 36, 36. Next, the arms 11a and 11b are pulled up using the lever wheel 3 or the hanging string 4. At this time, the ends 12 of the arms 11a and 11b
a and 12a rotate in the directions of arrows C1 and C2 shown in FIG. Thereby, the holding plates 13 and 13 move in the directions of the arrows D1 and D2 relative to the lid 32. At this time, the side surfaces of the holding plates 13, 13 and the tapered surfaces of the notches 37, 37 abut against each other, and the barbs 17, 17 are engaged with the bottom edge of the lid 36, so that the lid 36 is securely inserted. Is sandwiched between. Thereafter, when the arms 11a and 11b are further pulled up, the lid 36 is supported by the barbs 17 and 17 while being held by the holding plates 13 and 13 and is moved upward in the direction of arrow A. In addition, the front end side of the holding plate 13 (return 1
The cover 36 can be more securely held by bending the (7 side).

As described above, since the detaching apparatus 1 has a very simple structure, it can be manufactured at a low cost, and can be easily raised and lowered while securely holding the lids 32 and 36. Therefore, the detaching device 1 is provided in each home or business unit, and when the gutter 31 is cleaned, each person can attach and detach the lids 32 and 36 using the detaching device 1. Further, since the arms 11a and 11b are configured to be separable, the arms 11a and 11b can be used as crowbars, and since they are not bulky in the separated state, they can be easily carried and stored.

The present invention is not limited to the above embodiment. For example, in the embodiment of the present invention, an example has been described in which the arms 11a and 11b are formed by punching an iron plate into a predetermined shape. However, the structure of the arms 11a and 11b is not limited to this, and an iron pipe or square material (wood) is used. It can also be formed using such as. In addition, the length and angle of each part
It can be changed appropriately according to the size and shape of the lid to be detached.

[0030]

As described above, according to the gutter lid holding device of the first aspect, the two arms are provided so as to be rotatable in a scissor shape about the shaft member. Due to the weight of the gutter cover added to the return of the holding portion in the arm, the gutter cover is sandwiched by both the holding portions, so that the gutter cover can be raised and lowered easily and securely, and the configuration is simple. It is possible to provide a gutter lid holding device capable of attaching and detaching various gutter lids having different lengths while reducing manufacturing costs while reducing failures.

Further, according to the gutter lid holding device of the second aspect, since a plurality of shaft insertion holes are provided in both arms in parallel, the shaft insertion hole at a position corresponding to the length of the gutter lid is provided. By inserting the shaft member, the barb can be reliably engaged with the bottom edge of the gutter cover, and as a result, it is possible to raise and lower various gutter covers having different lengths.

Furthermore, according to the gutter lid holding device of the third aspect, since the included angle between the arm and the holding portion is set to be approximately 120 °, the gutter lid is turned back by its own weight. The lid can be held most efficiently.

According to the gutter lid holding device of the fourth aspect, the included angle between the barb and the longitudinal direction of the holding portion is set to approximately 80 °, so that the barb pierces the bottom edge of the gutter cover. Therefore, it is possible to reliably prevent the gutter lid from falling off in the sandwiched state.

Furthermore, according to the gutter lid holding device of the fifth aspect, since the holding portion is formed in a thin plate shape as a whole, the holding portion can be easily inserted between the adjacent gutter lids. . In addition, the barb can be easily formed by bending the distal end portion of the holding portion or fixing it to the holding portion by welding.

Further, according to the gutter lid holding device of the sixth aspect, the use of the suspension string inserted through the insertion hole and tied makes it possible to compare the holding of the gutter lid with both arms with both hands. As a result, the work of attaching and detaching the gutter lid can be performed more easily. Also, by inserting a handle bar into the insertion hole, it can be used as a burl.

Further, according to the gutter cover holding device according to the seventh aspect, since the other ends of both arms are bent in the thickness direction, the two arms can be used, for example, between the adjacent gutter lids.
