[0004]

However, in the case of the above-mentioned mounting structure, at least two workers are required to mount the hot and cold water mixing tap, and one worker is required to work under a narrow and dark sink. Because it was forced, workability was poor and it took a lot of time.

An object of the present invention is to provide a faucet mounting structure in which one worker can easily and reliably attach a faucet to an upper plate by only working from above the upper plate such as a sink. It is in.

[0006]

A faucet mounting structure according to the present invention includes a faucet mounting annular pedestal arranged at an upper edge portion of a through hole formed in a faucet mounting portion of a top plate such as a sink. A lower engagement member arranged below the upper surface plate through the through hole is fastened with the first bolt and the second bolt so as to sandwich the upper and lower edge portions of the through hole, and thereby the pedestal is attached to the upper surface plate. Is a water faucet mounting structure in which a water faucet is fixed to the base. The lower engagement member includes a first engagement piece and a second engagement piece, and a connecting piece whose both ends are connected to one ends of both engagement pieces so as to be rotatable about a horizontal axis. It is formed so that it can pass through the through hole when it is bent in a crank shape, and the upper surfaces of both engaging pieces can engage with the lower edge portion of the through hole when it is horizontally extended. The first bolt is passed through a bolt insertion hole formed in the inner peripheral edge portion of the pedestal, the bolt head is engaged with the upper edge portion of the hole, and the screw formed on the first engaging piece. It is screwed into the hole. The second bolt is screwed into a screw hole formed in the second engaging piece, and when the lower engaging member is passed through the through hole of the upper plate, the lower engaging member has a crank shape. The first bolt close to the first bolt so that it has a bent shape.
When the pedestal and the lower engaging member are arranged at a position, the bolt head has the bolt head at the inner peripheral edge portion of the pedestal so that the lower engaging member extends in the horizontal direction. It is arranged at a second position where it is hooked on a bolt hooking portion formed at a predetermined distance from the insertion hole.

If the above faucet mounting structure is adopted, the faucet mounting work can be performed only from above the top plate as follows, for example. That is, first, the lower engagement member is connected to the pedestal by the first bolt, and the second bolt screwed into the second engagement piece of the lower engagement member is arranged at the first position. The lower engagement member has a crank-like bent shape. Then, in this state, the lower engagement member is passed through the through hole of the upper surface plate from above. At this time, since the lower side engaging member has a compact shape bent in a crank shape, it can smoothly pass through the through hole. Then, when the lower engagement member is arranged below the upper plate through the through hole, the pedestal is placed on the upper edge portion of the through hole. In this way, when the second bolt is moved from the first position to the second position, the lower engaging member bent in a crank shape is extended horizontally. Next, when the first bolt and the second bolt are sequentially rotated in the tightening direction, each of the first engaging piece and the second engaging piece is gradually moved upward, and the upper surface thereof is below the through hole. Each bolt is rotated until it engages with the edge portion, and further, the upper and lower edge portions of the through hole are sandwiched between the pedestal and each engagement piece. As a result, the pedestal is firmly fixed to the top plate. Finally, the faucet is attached to the pedestal by appropriate means.

In the water faucet mounting structure according to the present invention, the lower engaging member is rotatable around the horizontal axis about the first engaging piece and the second engaging piece, and both ends are at one end of both engaging pieces. Instead of having the connecting piece coupled to the lower engaging member, the lower engaging member has a first engaging piece and a second engaging piece, and both ends are attached to one end of both engaging pieces around the horizontal axis. The first connecting piece rotatably connected to each other and both end portions thereof may include the second connecting piece rotatably connected to the other end portions of both engaging pieces about the horizontal axis.

Even when the lower engaging member of the faucet mounting structure is constructed as described above, the faucet can be mounted by working only from above the top plate in the same manner as described above. . In particular, in the case of the lower engaging member having the above-mentioned configuration, since the whole is formed in an annular shape by both engaging pieces and both connecting pieces, the upper surface portion of both engaging pieces engaging with the lower edge portion of the through hole is In addition to being able to take a larger area, the tightening force of the first bolt and the second bolt is likely to be evenly applied to the lower edge of the through hole, so that the pedestal and eventually the faucet attached to it are said to be stable. There are advantages.

In the water faucet mounting structure according to the present invention, the lower engagement member has a crank shape so that the first engagement piece is located above the second engagement piece when the lower engagement member is passed through the through hole of the upper plate. It is preferable that it has a bent shape.

When the lower engagement member is bent in the above-described manner when it is passed through the through hole of the upper plate, the length of the portion of the first bolt located between the pedestal and the first engagement piece is increased. Since it can be screwed into the first engagement piece to such an extent that the length is slightly larger than the thickness of the counter, the tightening distance of the first bolt in the subsequent fastening step is short, and the work is easy. Also, the second bolt can be screwed into the second engaging piece to the same extent as in the case of the first bolt, but in this case, the bolt head of the second bolt is below the hooking portion of the pedestal. Therefore, it is necessary to consider so that the second bolt can be pulled up through the pedestal.

In the faucet mounting structure according to the present invention, the first
Misalignment preventing projections may be formed on the upper surfaces of the engaging piece and the second engaging piece.

In the above case, the upper surface is engaged with the lower edge portion of the through hole when the pedestal and the lower engagement member are fastened by the first bolt and the second bolt, or after both are fastened. Moreover, there is no fear that both the engaging pieces will be displaced in the horizontal direction, and the pedestal can always be fixed at an accurate position.
