Thereby, a top plate is clamped by a base and a seat metal fitting, and it will be in the state where the base was fixed to the upper side of a top plate. And by attaching a faucet to the base fixed to the upper side of the top plate, it is possible to attach the faucet from the upper side to the attachment hole.

  By the way, in the faucet attachment apparatus of patent document 1, the folded metal fitting had to be developed under the top plate through the attachment hole, and there was a problem that it took time to develop the metal fitting. On the other hand, this foldable annular seat fitting can be replaced with a pinch member formed in a horseshoe shape, and inserted into the mounting hole from one end of the pinch member and positioned below the top plate. A faucet mounting device that can be used has been proposed (Patent Document 2).

  However, in the faucet mounting devices of Patent Document 1 and Patent Document 2, a male screw is inserted into the screw hole of the seat bracket or the like through the through hole of the base with respect to the seat bracket or the sandwiching member disposed below the top plate through the mounting hole. When fastening a member, the connecting material that pulls up the seat bracket is flexible, so it is difficult to align the through hole of the base and the screw hole of the seat bracket. That is, there is a problem that it takes time to fix the base.

  In view of the above circumstances, an object of the present invention is to provide a faucet mounting device that can be easily fixed from above to a mounting hole of a top plate such as a sink or a counter.

In order to solve the above-described problems, the faucet mounting device according to the present invention includes a cylindrical upper body portion to which a faucet is attached, a bulge from an inner peripheral surface of the upper body portion, and a lower surface of the upper body portion.

  Here, examples of the “polygon” include a quadrangle, a hexagon, and the like. In addition, the “extending portion” may be detachable from the shaft portion, or may not be removable from the shaft portion.

  The faucet mounting device according to the present invention has a first through hole penetrating the upper main body portion and an inner diameter mounting hole facing the second through hole at a position where a faucet of a top plate such as a sink or a counter is mounted. Can be fixed from above. Specifically, first, the second male screw member is removed from the upper fixing member, the first head of the first male screw member inserted into the first through hole is brought into contact with the upper surface of the upper main body part, The lower fixing member is brought into contact with the extended portion at the lower end of the first male screw member. As a result, the guide member and the first male screw member extend downward from the upper fixing member, and the lower fixing member is positioned at the lower ends of the guide member and the first male screw member. The lower fixing member is in the most distant state.

  In this state, the lower fixing member is inserted into the mounting hole of the top plate in an inclined state from the upper side, the lower fixing member is positioned on the lower side of the top plate, and then the upper fixing member is placed on the top plate. Then, by moving the first male screw member upward, the lower fixing member in contact with the extending portion at the lower end of the first male screw member is raised together with the first male screw member, and the lower fixing member is It contacts the lower surface of the plate. At this time, since the guide member is inserted into the guide hole of the lower fixing member so as to be slidable and non-rotatable, the lower fixing member rises without rotating around the axis extending vertically. That is, the lower fixing member ascends with the second female screw hole positioned coaxially with respect to the second through hole of the upper fixing member.

  Then, with the lower fixing member in contact with the lower surface of the top plate, the second male screw member of the second male screw member is inserted from above into the second through hole of the upper fixing member, and the second male screw member Is rotated in the tightening direction, the second male screw portion is screwed into the second female screw hole of the lower fixing member. By tightening the second male screw member in this state, the second male screw member is fastened with the top plate sandwiched between the upper fixing member and the lower fixing member.

  After that, by rotating the first male screw member in the tightening direction and tightening the first male screw member, the top male plate is fastened with the upper fixing member and the lower fixing member sandwiched on the first male screw member side. Is done. Thus, the faucet attachment device is fixed to the top plate, and the faucet can be attached to the top plate by attaching the faucet to the upper fixing member of the faucet attachment device.

  Thus, according to the faucet mounting device of the present invention, the lower fixing member is inserted into the mounting hole formed in the top plate from above, and then upward through the first male screw member. Since the second through hole of the upper fixing member and the second female screw hole of the lower fixing member can be made to coincide with each other simply by moving and contacting the lower surface of the top plate, the second male screw member can be It can be easily screwed into the female screw hole, and the faucet attachment device can be easily fixed to the attachment hole of the top plate from above.

  According to the faucet mounting device of the present invention, since the first through hole, the second through hole, and the guide member are arranged inside the cylindrical upper main body, the first through hole and the second through hole are arranged. Compared to the case where the hole is made to penetrate through the cylindrical portion of the upper main body, the inner diameter (inside width) of the upper main body is relatively increased when the outer diameter of the upper main body is the same. Can do. Accordingly, the supply pipe extending downward from the lower end of the faucet can be easily passed through the cylindrical upper main body, and the faucet can be easily attached.

  In addition to the above-described configuration, the faucet mounting device according to the present invention may include: “The first male screw member extends downward from the lower end of the first male screw portion in a bar shape and has an outer diameter of the first male screw member. It further includes a shaft portion having a smaller diameter than the male screw portion, and the extension portion is provided at the lower end of the shaft portion.

  By the way, as for the length of the first male screw portion and the second male screw portion, the thickness of the lower fixing member (the height in the vertical direction) is larger than the thickness of the top plate to which the faucet mounting device of the present invention is fixed. At least the length added). In the case where these first male threaded portions have a minimum length, the space between the upper fixing member and the lower fixing member before being fixed to the top plate becomes narrow, so when trying to insert the lower fixing member into the mounting hole There is a problem that the upper fixing member hits the top plate and cannot be inserted into the mounting hole. Therefore, by making the first male screw part long enough so that the lower fixing member is far away from the upper fixing member, the upper fixing member does not hit the top plate when the lower fixing member is inserted into the mounting hole. Thus, it is conceivable to make it possible to insert into the mounting hole. However, when the first male screw part is sufficiently long, the number of times the first male screw member or the second male screw member is rotated when screwed into the first female screw hole or the second female screw hole and tightened. There is a problem that the amount of fixing becomes more than necessary and the fixing work is troublesome.

  On the other hand, in the present invention, since a small-diameter shaft portion is provided at the lower end of the first male screw portion of the first male screw member and an extension portion is provided at the lower end of the shaft portion, for example, the first When the length of the male screw part is the minimum necessary length, the lower fixing member can be sufficiently separated from the upper fixing member by positioning the lower fixing member at the lower end of the shaft part. When the first male screw member is fastened, the number of rotations of the first male screw member can be minimized and the time required for fixing work can be reduced. it can.

  Thus, according to the present invention, it is possible to provide a faucet attachment device that can be easily fixed from above to the attachment holes of the top plate such as a sink or a counter.
