Description

TECHNICAL FIELD The present invention relates to a side gutter lid hanging tool used for installing or removing a side gutter lid that covers an installed U-shaped groove at an end of a road.

Conventionally, there is Patent Document 1 as an apparatus for lifting a side groove lid. The device disclosed in Patent Document 1 is a device in which three mechanisms such as a clamp fitting, a clamp suspension fitting, and a lifting device are combined in a functional and compact manner.
The suspension device is configured such that a clamp fitting is inserted and hooked into a rainwater groove formed on the side groove cover, is lifted by a lifting device via the clamp suspension fitting, and is movable.

JP 2001-295359 A

In general, the side groove cover is placed in a laminated state before use, and in use, the side groove cover is separated and transported by hand, and placed on the U-shaped groove. As described above, since the work is performed manually, there is a problem in terms of safety in the work by pinching the hand.
The device disclosed in Patent Document 1 inserts a clamp fitting into a rainwater groove, but there is a problem that the clamp fitting does not function because there is no gap when the side groove cover is in a laminated state.
Accordingly, the present invention provides a side gutter lid hanger for overcoming such a problem.

The hanging device for the side groove cover according to claim 1 suspends the side groove lid through a rainwater groove formed through from the front surface to the back surface, and the suspension device has a support at the end of the shaft body coupled to the operating body. The holder is attached to the upper part of the shaft body, and a presser body that can be moved up and down is inserted into the shaft body, and a spring is inserted between the presser body and the receiver body.
Further, on the back side of the side groove cover, a rotation groove is formed in which the support can be rotated after the support is inserted into the rainwater groove.
Moreover, the suspension tool according to claim 2 has a rotation stop groove formed at an arbitrary angle with respect to the rainwater groove in the rotation groove, and the support is inserted into the rotation stop groove, whereby the suspension tool The operation body is prevented from rotating, and the support body does not come out of the rainwater groove and can be hung more safely.

The hanging tool of the present invention can suspend the side groove lid safely with a simple configuration.

It is a perspective view of lamination | stacking the groove | channel side cover of a U-shaped groove. It is a perspective view of the back surface of a gutter lid. It is a front view of a hanging tool. It is a figure of the operation preparation stage of a hanging tool. Back view of gutter lid with hanging tool inserted in rainwater gutter It is a reverse view of the gutter lid in a state where the lifting tool is rotated and can be lifted. It is a surface view of the gutter lid in a state where the lifting tool is rotated and can be lifted.

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a laminated state of a groove side lid 1 of a U-shaped groove having a U-shaped cross section. FIG. 2 is a perspective view of the back surface of the gutter lid. FIG. 3 is a front view of the hanger. 4-7 is a figure which shows operation which lifts a gutter lid using a hanging tool.

The concrete side groove lid 1 is used as a lid for a concrete U-shaped groove having a U-shaped cross section. In the center of the side groove lid 1, elongated rainwater grooves 2 are formed at two positions on the front and rear sides so as to penetrate from the front surface to the back surface.
Further, a concave rotating groove 3 is formed on the back surface of the side groove cover 1 in a range including the rainwater groove 2. Note that the diameter of the rotating groove 3 is formed larger than the length of the support body 12 of the hanger described later, and the support body 12 can be rotated.

A concave rotation stop groove 5 is formed inside the rotation groove 3 at a predetermined angle with respect to the rainwater groove 2. The rotation stop groove 5 of this example is formed perpendicular to the rainwater groove 2. Further, the rotation stop groove 5 is longer than the length of the support 12 attached to the hanging tool described in detail later, and the depth at which the rotation is prevented when the support 12 enters the rotation stop groove 5. It is a groove.
Although the rotation stop groove 5 will be described in detail later, it is not always necessary.

Next, the hanging tool in FIG. 3 will be described. A shaft body 11, which is a metal round bar, is vertically coupled to the center of the operation body 10, which is a metal round bar. A support 12 is attached to the end in parallel with the operating body 10. The support 12 is a metal round bar that can be rotated in the rotation groove 3 after being inserted from the rainwater groove 2 and can be inserted in the rotation stop groove 5.
The mounting direction of the support body 12 is preferably parallel to the operation body 10 because the position (direction) of the support body 12 is easy to understand when the operation body 10 is rotated, but it is not necessarily parallel.

  A disc-shaped receiving body 13 that receives a repulsive force of a spring 15 to be described later is fixedly attached to the upper portion of the shaft body 11. Further, a disc-shaped presser member 14 that can be raised and lowered is inserted into the shaft body 11, and a spring 15 is inserted between the shaft body 11 and the receiving body 13.

Next, with reference to FIG. 4 to FIG. 7, an operation of lifting the side groove lid 1 using the lifting tool shown in FIG. 3 will be described. FIG. 4 is a stage for preparing the operation of the hanger, FIG. 5 is a rear view of the side groove lid 1 in which the hanger is inserted into the rainwater groove 2, and FIG. 6 is a rear view of the side groove lid 1 in a state in which the hanger can be rotated and lifted. FIG. 7 is a surface view of the side groove lid 1 corresponding to FIG.
In addition, description of operation which lifts the side groove cover 1 using a hanging tool is only one side, and the other hanging tool is the same.

First, when holding the operating body 10 of the lifting tool (FIG. 4) and inserting the support body 12 from the rainwater groove 2 formed in the side groove cover 1, the presser body 14 is placed on the surface of the side groove cover 1 to be a spring. 15 is compressed, and the support body 12 reaches the rotation groove 3 formed on the back surface of the side groove cover (FIG. 5).
Next, the operating body 10 is rotated so that the support body 12 is fitted into the rotation stop groove 5, and when the hand is released from the operating body 10, the support in the fitted state in the rotation stop groove 5 is caused by the repulsive force of the spring 15. The body 12 is clamped with the presser body 14 placed on the surface of the side groove lid 1.
Therefore, the operating body 10 cannot be rotated horizontally, and the support body 12 does not leave the rotation stop groove 5 and come out of the rainwater groove 2 (FIGS. 6 and 7).
Even if the operating body 10 in this state is lifted by an elevator (not shown), the support 12 is prevented from rotating, and the support 12 does not come out of the rainwater groove 2, so that it can be lifted more safely.

Note that the lifting tool is removed from the state in which the above-described lifting tool is mounted on the side groove lid 1 by first holding the operating body 10 and pressing downward to compress the spring 15 to support 12. Is detached from the rotation stop groove 5. Next, the operating tool 12 is rotated so that the support 12 is aligned with the rainwater groove 2, and then pulled up, the lifting tool can be removed from the side groove lid 1. In other words, since the hanging tool in this state cannot be removed from the rainwater groove 2 unless the hanging tool is pressed down, it is safe because it does not come off even if the lifting operation is performed.

Although the rotation stop groove 5 is formed on the back surface of the side groove lid 1, when the spring 15 is slightly strong, the support body 12 is strongly sandwiched between the back surface of the cover and the rotation of the support body 12. Since it is possible to prevent the support 12 from coming out of the rainwater groove 2, the rotation stop groove 5 is not necessarily required, and can be lifted with care so as not to rotate after the suspension tool is mounted. The rotation stop groove 5 is not necessarily required.
Moreover, although the lifting tool of this application is a thing with respect to a gutter lid, it cannot be overemphasized that the target to lift is not limited to a gutter lid.
