Description

Aspects of the present invention generally relate to wash counters.

In the washbasin counter, a rising portion extending upward from the rear end of the counter is provided, and a shelf plate protruding forward from the upper end of the rising portion is provided to secure a sufficiently large hand-washing space and to provide a sufficiently large space. It has been proposed to secure space for luggage storage. In such a wash counter, it is necessary to ensure the strength of the shelf board so that the shelf board is not bent or damaged by a load from above.

On the other hand, the faucet portion for discharging water is provided with an opening at the rising portion, and is attached to the rising portion in a state of being inserted through the opening. At this time, if the vertical distance between the shelf board and the faucet part is large, the shelf board becomes excessively high and it becomes difficult to place luggage, etc., or conversely, the faucet part is lowered too much, resulting in a hand-washing space. Becomes narrower. Therefore, in order to secure the widest possible hand-washing space while setting the shelf board at an appropriate height, it is necessary to arrange the faucet part near the upper end of the rising part and bring the faucet part and the shelf board close to each other. ..

When arranging the faucet part near the upper end of the rising part, if the faucet part is inserted through the through-hole-shaped opening and attached, the wall thickness of the part from the opening to the upper end of the rising part becomes thin, and the faucet part becomes thin. When an external force is applied to the faucet, the thin part above the opening may be damaged.

For this reason, it has also been proposed to insert a faucet portion into a concave opening that is recessed downward from the upper end of the rising portion. That is, it has been proposed to form an opening in a shape obtained by removing a thin portion that may be damaged.

However, if the faucet portion is attached to the concave opening, a gap is generated above the faucet portion after the attachment. That is, the removed thin-walled portion appears as a gap. For this reason, it becomes difficult to suppress the infiltration of water into the space behind the rising portion. Further, if a member for ensuring the strength of the shelf board and a member for stopping water at the mounting portion of the faucet portion are individually prepared, the number of parts increases and the configuration becomes complicated.

For this reason, in a wash counter that provides a shelf plate at the upper end of the rising portion, even when the faucet portion is attached to a concave opening that is recessed downward from the upper end of the rising portion, the strength of the shelf plate is suppressed while suppressing an increase in the number of parts. It is desired that the water faucet can be appropriately secured and the water faucet attachment portion can be appropriately stopped.
