Description

[Detailed Description of the Invention] [Field of Use and Outline of the Invention] The present invention is to mount a metal fitting for a gas cock, in particular, a gas cock which is connected to a terminal of a flexible pipe through a joint and has a flange on a wall surface. The present invention relates to a mounting metal fitting used at that time, which is inserted into the rear surface of a wall plate while being externally fitted to a joint connected to a pipe terminal drawn out from the wall plate, and is attached and fixed to the rear surface. .

[Prior Art and its Problems] The conventional metal fitting for attaching a gas cock (1) is a substantially U-shaped plate-like body having fixing cords (12) and (12) as shown in FIG. Using the shape, the wall cord is inserted into the back side of the wall through an opening (30) provided in the wall constituting member (3) that is smaller than the metal fitting, and the fixing cord (1
2), (12) are pulled out, and the fixing string (12),
(12) is pulled and fixedly attached to the back surface of the wall component (3), and this and the flange of the gas cock are screwed together.

In this case, it is difficult to insert the metal fitting into the back side of the wall surface constituting member (3) through the gap of the opening (30) in a state where the flexible pipe is pulled out from the opening (30). It is difficult to work because the fixing cords (12) and (12) must be pulled up from the surface and screwed to the flange of the gas cock.

This is because the mounting bracket (1) is a rigid body,
The opening (30) smaller than this has to be inserted into the back side of the wall component (3) by a complicated operation, and when the fitting (1) is attached to the pipe terminal in advance, it passes through the opening. This is because it cannot be done.

[Technical Problem] The present invention provides a gas cock (G) having such a “flange (F) and screw-connected to the end of the flexible tube (2) through a joint (20). In the gas cock mounting metal fitting for mounting on the wall surface component (3), it is a technical problem to be able to be inserted into the back surface of the wall surface component (3) in a state of being connected to the flange (F) in advance. .

[Technical Means] The technical means of the present invention taken in order to solve the above technical problem is "a plurality of mounting screws (5) and (5) penetrating the flange (F) are screwed together and a joint (20 ), And a gas cock (G) for the support plate (11)
It is composed of a plurality of backing plates (10) (10) which extend along the side plane and are arranged at symmetrical positions with respect to each other, and the size of the support plate (11) is the wall component (3). The opening (3
Set the size so that it can be inserted into (0)
0) and (10) are arranged on the gas cock (G) side with respect to the support plate (11) and are supported by the support plate (11) so that they can be folded toward the gas cock side, and the backing plates (10) (10) )
The distance between the tip portions of the support plate (11) is set to be larger than that of the opening portion (30) and set in the folded state to be smaller than that of the opening portion (30). 1
0) (10) Depart from these pad plates (10) (10)
More toward the gas cock (G) than the gas cock (G), and the outer diameter of the peripheral portion of the protruding portion is made substantially equal to the diameter of the opening (30). "
That is.

[Operation] The technical means of the present invention operates as follows.

The flexible tube is pulled out from the opening (30) formed in the wall surface forming member (3), and a joint (20) for connecting to the gas cock (G) is attached to the end of the flexible tube.

Next, the fitting (1) is fitted onto the joint (20) and the gas cock (G) is provided with a flange (F).
Screw together. At this time, the mounting bracket (1) is externally fitted so that the support plate (11) is located on the flexible tube side and the contact plate (10) is located on the gas cock (G) side.

Then, a predetermined interval is provided between the mounting metal fitting (1) and the flange (F), and mounting screws (5) and (5) penetrating the flange (F) are used to support the mounting metal fitting (1). The two are connected by being screwed into a screw hole provided in the plate (11). That is, the gas cock (G), the flange (F), the mounting fitting (1) and the joint (20) are integrated.

In this state, the fitting (1) is pushed into the opening (30) until it is located on the back side of the wall constituting member (3). At this time, since the support plate (11) located on the flexible tube side is smaller than the opening (30), it can be inserted, but the maximum diameter part of the backing plate (10) integrally attached to the opening is open. Since it is larger than the portion (30), the backing plate (10) comes into contact with the outer peripheral surface of the opening (30). However, since the backing plate (10) is foldably attached to the supporting plate (11), when the mounting metal fitting (1) is further forcibly pushed in, the backing plate (10) becomes a gas cock (G). It swings to the side, the distance between its tip portions is reduced, and it is inserted through the opening (30). After the insertion, when the backing plate (10) is returned to the overhanging state, the backing plate (10) and the peripheral edge of the opening (30) are engaged with each other to prevent them from coming off.

In this way, the mounting bracket (1) is attached to the wall component (3).
The flange (F) is brought into contact with the surface of the wall surface constituting member (3) so that the mounting metal fitting (1) comes into contact with the back surface of the wall surface constituting member (3). ), (5) are screwed together to fix the flange (F) and the mounting bracket (1) on both sides of the wall surface constituting member (3). As a result, the gas cock (G) is fixed to the wall surface constituting member (3).

During the above-mentioned mounting work, the parts of the support plate (11) that are off the contact plates (10) (10) are removed from the contact plates (10).
Since it projects more toward the gas cock (G) than the (10) and the outer diameter of the peripheral edge of this projection is substantially the same as the diameter of the opening (30), it is possible to perform the above-mentioned mounting work even under the condition that it is not visible. It is easy to ensure the concentricity between the opening (30) and the mounting bracket.

[Effects] Since the present invention has the above-mentioned configuration, it has the following unique effects.

Since the flange (F) of the gas cock (G), the mounting metal fitting (1) and the joint (20) can be fixed to the wall surface constituting member (3) as they are, the wall surface structure of the gas cock (G) can be fixed. The work of attaching to the member (3) is simplified, and the inconvenience that it is difficult to insert the attachment metal fitting (1) through the opening (30) and the inconvenience that it is difficult to fix it to the back surface of the wall surface component (3) are solved. To be done.

In order to secure the mounting strength of the gas cock, it is important to secure the concentricity between the mounting bracket (1) and the opening (30), but since the concentricity is easily secured during the mounting work, The workability of the mounting work is improved, and the mounting strength is strong and stable.
