Description

The present invention relates to a fixture for attaching a pair of mixed faucet joints to a side wall of a unit bath, and more particularly, the present invention relates to a fixture for fixing a faucet elbow to the back side of a side wall of a unit bath. It is.

In order to attach the hot and cold water faucet to the side wall of the unit bath, the pair of water faucet joints inserted through the side wall of the unit bath can be easily and efficiently fixed to the side wall, and the wall shape and wall thickness of the unit bath Therefore, there is a demand for a fixture for a mixed faucet that can cope with these differences.

As an example of a method for fixing a mixing faucet joint in a conventional unit bath, a U-shaped or channel-shaped fixture for fixing the mixing faucet joint is attached in advance to the back of the side wall of the unit bath, and a pair of the fittings is attached to this fixing fixture. After attaching the faucet elbow of the faucet and inserting the end fitting threaded part of the faucet elbow into the through hole drilled in the side wall of the unit bath, fasten the fixing nut to the external screw of the faucet elbow from the inside of the unit bath. In addition, a method is known in which a faucet elbow is sandwiched between the side walls of the unit bath and a mixing faucet for unit bath is connected to the internal thread portion of the faucet elbow from the inside of the unit bath.

Thus, JP-A-7-268915 (hereinafter referred to as Patent Document 1) is disclosed as a mounting fixture of the type described above. In Patent Document 1, a nut is fixed to a corner of a channel-shaped support plate in which a through hole for inserting a faucet elbow is formed, and a long bolt that is screwed to the nut protrudes to the side of the support plate. So, it is possible to fix the faucet elbow through the support plate just by forming the insertion hole of the long bolt on the lightweight steel base, not only the wooden system like the conventional mounting fixture It provides a faucet elbow mounting fixture that can be mounted and fixed on a lightweight steel base, allowing the work to proceed without being affected by the finishing wall work and piping work processes, and thus improving work efficiency.

Japanese Patent No. 3304075 (hereinafter referred to as Patent Document 2) is disclosed as a joint for a mixed water faucet using a fixed plate as a connecting material bent into a U-shape. Patent Document 2 includes a plurality of cylindrical bodies that are connected to the introduction portion of the mixed water faucet at the first piping connection portion and are connected to the resin pipe at the second piping connection portion, and are provided with a male screw portion on the outer periphery of each cylindrical body. Each cylindrical body is formed by inserting each cylindrical body into a mounting hole drilled in the support wall, screwing a pair of nuts into the male threaded portion from both sides of the support wall, and tightening the support wall with the nut. The body is attached to the support wall, and the axis of the pipe connected to each cylindrical body intersects with the rotation axis of the nut screwed into the male screw portion of the cylindrical body at a predetermined angle. A coupling faucet for connecting a plurality of cylindrical bodies with a connecting member having an insertion hole through which the cylindrical body is inserted, and a locking portion that engages with each cylindrical body and the connecting member. Providing the cylindrical body and the connecting member to prevent relative rotation, and A pair of any mixing faucet fittings provided with a regulating member for regulating the one rotation of the nut to be screwed on the externally threaded portion of the tubular body forming member.

Therefore, in Patent Document 2, when fixing a mixing faucet by tightening a pair of nuts from both sides of a support wall (a wall surface of a unit bath or the like), the upper end edge and the lower end edge are folded on one side of the support wall to form a stopper. One of the nuts is attached through the fixed plate of the U-shape, and the rotation of the nut is restricted by engaging the opposing two sides of the mounting nut, the stoppers on the upper edge and the lower edge. When the nut is rotated, the other nut can be prevented from rotating in the same direction, so that the nut can be securely tightened or loosened without fixing the other nut again. is there.

Furthermore, a faucet elbow fixture for attaching a mixing faucet to the wall of a unit bath is also provided in a unit bath in which the cross-sectional shape of the main part is bent into a U-shape and ribs are formed on the back of the wall. Japanese Patent Laid-Open No. 2006-265832 (hereinafter referred to as Patent Document 3). Patent Document 3 is a fixture for fixing a faucet elbow to the back of the side wall of the unit bath in order to attach the faucet to the side wall of the unit bath. A plurality of support portions for supporting the elbow; and a connection portion for connecting the support portions, wherein the connection portion is in a state where the support portion is in contact with the wall back of the side wall, In order to form a space portion for avoiding interference with the side wall, it is formed by bending from the support portion, and the water inside the wall is straddled across the ribs on the back of the wall. A faucet elbow fixture having a U-shaped cross-section of a main part that can be arranged on the back of the wall corresponding to the arrangement position of the plug is also provided.

Thus, in each of the conventional techniques disclosed in Patent Documents 1 to 3, a U-shaped or channel-shaped fixing tool for fixing a faucet elbow is attached in advance to the rear surface of the side wall of the unit bath. Attach a pair of faucet elbows to the fixture, insert the tip joint threaded part of the faucet elbow into the through-hole drilled in the side wall of the unit bath, and fix it to the external screw of the faucet elbow from the inside of the unit bath This is a fixture for fastening a nut to clamp the faucet elbow on the side wall of the unit bath, and connecting the mixing faucet for unit bath from the inside of the unit bath to the internal thread portion of the faucet elbow joint.

The prior arts disclosed in Patent Documents 1 to 3 each have a clear problem and means for solving the problem, but as a common drawback, inspection after completion of assembly of the side wall of the unit bus, or When removing the mixing faucet during renovation, the faucet elbow fixing nut (fitting elbow tightening nut) provided on the inner wall side of the unit bath is mistakenly removed and the faucet elbow is behind the side wall of the unit bath. There were times when I fell.

In the prior art disclosed in Patent Documents 1 to 3, for example, Patent Document 3 presents a solution when a reinforcing rib is interposed on the back surface of the side wall of the unit bus. As a common defect of Patent Document 3, there is a case where the wall thickness of the unit bath is different for each manufacturer of the unit bath, and the end dimension of the faucet elbow cannot be adjusted to the wall thickness. The connection end face of the screw may protrude abnormally, preventing proper installation.

JP-A-7-268915 Japanese Patent No. 3304075 JP 2006-265832 A
