DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for operating a height adjusting bolt for a waterproof pan, a bathtub, etc., constituting a floor of a unit bath room or the like.

[0002]

2. Description of the Related Art When a waterproof pan constituting a floor such as a unit bath room is installed, it is necessary to adjust the height of the pan. A tool 104 such as a screwdriver is inserted through a hole 102 provided on the wall surface of the
0, the engagement groove 108 at the upper end of the height adjustment bolt 106
, And a rotating operation is performed.

[0003]

However, the waterproof pan 10
In some cases, the distance between the hole 102 provided in the wall surface and the upper end of the height adjustment bolt 106 may be long (for example, about 300 mm) depending on the type of 0, etc. In this case, a long tool 104 must be used. In addition to the above, the following inconveniences arise.

That is, since the operator cannot visually check the upper end of the adjusting bolt 106, the adjusting operation of the bolt 106 becomes blind and it is difficult to find the upper end of the bolt. Even if the tool 104 can be engaged with the engagement groove 108, if the tip of the tool 104 is displaced during the operation, the tool tip is disengaged from the engagement groove 108, and the upper end of the bolt is searched again to engage the engagement groove. There is a great difficulty in height adjustment work, such as the need to engage the gear 108.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and the gist of the present invention is to provide a height adjusting bolt provided to adjust the height of a waterproof pan, a bathtub, and the like. An engaging portion is formed on an upper end surface, and a female screw member is screwed into an upper end portion of the height adjusting bolt so that an upper end portion of the bolt partially enters a female screw hole of the female screw member. A tip of a tool such as a screwdriver is inserted into the female screw hole from above to engage with the engaging portion of the adjusting bolt, and the height adjusting bolt is rotated.

[0006]

As described above, according to the present invention, the female screw member is mounted on the upper end of the adjusting bolt to operate the bolt. In this case, the blind work is performed using a long tool such as a screwdriver. It is easy to find the upper end of the bolt when rotating the adjusting bolt.

In addition, since the female screw hole of the female screw member serves as a guide hole, the tool tip can be easily engaged with the engaging portion at the upper end of the height adjusting bolt. The action prevents the tool tip from coming off the bolt engaging portion. This greatly simplifies the operation of the height adjustment bolt.

The present invention has an advantage that the female screw member is tightened after rotating the height adjusting bolt so that it can act as a lock nut.

As a result, after the waterproof pan or the like is installed with its height adjusted, it is possible to effectively prevent the height adjusting bolt from rotating due to vibration or the like applied to the waterproof pan and causing rattling. .

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; In FIG. 1, reference numeral 10 denotes a waterproof pan which forms a floor of a unit bath room or the like, and has a flange 12 which forms a wall surface on the periphery.

A through hole 14 is provided in the flange 12,
From here, a tool 16 such as a screwdriver can be inserted. 18 is a frame provided on the waterproof pan 10,
A nut 20 is welded and fixed thereto, and a height adjusting bolt 22 is screwed to the nut 20. That is, the height adjusting bolt 22 is connected to the waterproof pan 1 via the frame 18.
It is attached to 0.

The height adjusting bolt 22 has a head 24 for grounding at the lower end, and a single engaging groove 26 is formed on the upper end surface. A nut 28 is screwed into the upper end of the height adjusting bolt 22. The nut 28 is screwed so that the upper end of the height adjustment bolt 22 is partially inserted into the female screw hole 30.

In the method of the present embodiment, the tool 16 is connected to the peripheral flange 1 of the waterproof pan 10 with the nut 28 serving as a female screw member screwed to the upper end of the height adjusting bolt 22 as described above.
2 is inserted through the through hole 14 and its tip is engaged with the engaging groove 26 of the height adjusting bolt 22 to rotate the same. When the distance between the through hole 14 and the upper end of the adjusting bolt 22 is long, Even if it is necessary to perform the operation in a state where the upper end of the adjustment bolt 22 cannot be visually confirmed, the position of the upper end of the adjustment bolt 22 is adjusted by the presence of the nut 28 screwed to the upper end of the adjustment bolt. You can easily find it.

In addition, the tip of the tool 16 can be easily engaged with the engagement groove 26 of the adjusting bolt 22 by the guiding action of the female screw hole 30 of the nut 28, and the engagement of the female screw hole 30 is enabled after the engagement. The tip of the tool 16 is the engagement groove 2
6 is prevented from falling off. Therefore, according to the method of the present embodiment, the adjusting operation of the adjusting bolt 22 can be easily performed.

In the method of this embodiment, after the above operation is completed, the nut 28 is tightened as shown in FIG. 2 so that it can act as a lock nut. In this way, even when the adhesive for fixing the bolt head 24 is not working well, the adjustment bolt 22 can be reliably prevented from rotating, and the vibration applied to the waterproof pan 10 when a load is applied or the like. It is possible to effectively prevent the adjustment bolt 22 from rotating and causing rattling.

As shown in FIG. 3, a spacer member 32 may be interposed between the nut 28 and the frame 18. In this case, the amount of operation for tightening the nut 28 can be reduced. Obviously, the work becomes easier.

Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention can be applied when adjusting the height of a bathtub. The present invention can be implemented in various modified forms based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
