Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a hot water outlet fitting for a bathtub to which a water heater for supplying hot water to the bathtub is connected.

(Prior Art) Conventionally, the hot water outlet fitting of a bathtub to which a water heater that supplies hot water to the bathtub is connected, as shown in FIG. 2, insert and connect the discharge fitting 3 into the main body 1, and cover the discharge fitting 3 with a cover 4.
was tightened and attached to bolt 2. The hot water is discharged forward (in the axial direction) from the discharge fitting 3, and the direction of discharge into the bathtub is determined by the opening position of the cover 4.

(Problem to be solved by the invention) However, since the cover 4 is inside the bathtub,
The discharge port may change due to contact with the human body. As a countermeasure, it is possible to provide the discharge port 7 of the discharge fitting 3 on the circumferential side, but the discharge fitting 3 is simply inserted into the tightening bolt 2 and the tap fitting main body 1, and the cover 4 is provided for cleaning. When you remove it, your hand may touch it and the direction may change.

(Means for Solving the Problems) In order to solve the above problems, the present invention is characterized by the following configuration. That is, a hot water tap fitting body connected to a water heater, a hollow cylindrical tightening bolt having a threaded part screwed to the main body and a flange part that clamps and fixes the bathtub wall between the main body, and a tightening bolt. It consists of a discharge fitting that penetrates and is connected to the main body of the tap metal fitting and has a discharge port on the side, and a cover that covers the discharge fitting, and a rib is formed in the tightening bolt insertion part of the discharge fitting, and a rib is formed in the tightening bolt insertion part. It is characterized in that a plurality of locking pawls are formed on the circumferential surface so that the ribs are fitted between the pawls.

(Function) Screw the tightening bolt from the inside of the bathtub into the hot water outlet fitting body on the outside of the bathtub, and tighten and fix the bathtub wall at the flange. When screwing in, just use the locking pawl to turn it. Next, the discharge fitting is tightened and inserted into the bolt so that the discharge port faces in a predetermined direction. At this time, the rib is fitted between the locking claws. Since a large number of locking pawls are formed, the rib can be fitted no matter where the tightening bolt is stopped. Then just attach the cover.

(Example) The present invention will be specifically described below based on an illustrated example.

Reference numeral 1 denotes a main body of a hot water tapping fitting, one end of which is connected via piping to a water heater (not shown), and the other end is open and has a threaded portion 11 formed on its inner circumferential surface. 2 is a tightening bolt, and the threaded part 2 is screwed into the threaded part 11 of the main body 1.
1 and a flange portion 22 for sandwiching and fixing the bathtub wall between the body 1 and the bathtub. A large number of locking pawls 5 are formed on the inner circumferential surface of the tightening bolt 2, and the spacing between the pawls 5 is maintained such that a rib, which will be described later, is fitted thereinto. 24 is a screw hole provided in the flange portion 22. Reference numeral 3 denotes a discharge fitting, which includes an insertion portion 31 that passes through the tightening bolt 2 and is connected to the tap fitting main body 1, a rib 32 formed on the outer periphery of the insertion portion 31, and the tightening bolt 2.
a flange 33 that comes into contact with the flange portion 22 of the
It consists of a discharge part 34 having a discharge port 7 on the side (lower side in this embodiment). Reference numeral 6 denotes a holding plate, which is fastened to the bolt 2 with screws and is fixed by sandwiching the flange 33 of the discharge fitting 3. 4
is a cover that covers the discharge fitting 3 that protrudes into the bathtub, and the rear and lower surfaces are open.

Next, the operation of the above configuration will be explained.
The hot water fitting body 1 is placed on the outside of the through hole drilled in the bathtub.
, and tighten the bolt 2 from the inside, and screw the threaded portion 21 into the threaded portion 11 while turning the locking pawl 5 with your fingers or a jig. Next, the discharge fitting 3 is inserted into the tightening bolt 2 with its discharge port 7 facing downward. At this time, tighten bolt 2
No matter where the rotation stops, the rib 32
is fitted between the locking claws 5 and positioned. Next, the presser plate 6 is attached to the flange 33 and the discharge part 34.
and then screw the screw into the screw hole 24 of the tightening bolt 2. The flange 33 is then sandwiched and fixed between the presser plate 6 and the flange portion 22. Finally, the cover 4 is placed over the protrusion of the discharge fitting 3 into the bathtub. The cover 4 may be fixed to the discharge fitting 3 with screws. After the hot water outlet fitting is attached to the bathtub wall, the hot water outlet piping of the water heater and the hot water outlet fitting main body 1 are connected. Hot water is supplied from the water heater to the hot water tap main body 1, and is spouted into the bathtub from the discharge port 7 formed on the lower surface of the discharge part 34 of the discharge metal fitting 3. Hot water flows out from the cover 4 through a slit 41 provided on the side surface and an opening on the bottom surface. Incidentally, if it is desired to restrict the direction of ejection, a removable partition plate 8 may be attached within the cover 4.

(Effects of the invention) As described above, the present invention can position and prevent the discharge fitting from rotating simply by using the locking claws of the tightening bolts, resulting in a simple configuration and easy installation. This can be done more easily than positioning using screws. Furthermore, since a large number of locking pawls are formed, even if the tightening bolts are tightened differently depending on the thickness of the bathtub wall or the installer, the fitting can be ensured so that the discharge port faces in the predetermined direction.
