Description

[Detailed Description of the Invention] [Field of Use and Outline of the Invention] The present invention relates to a fixture for a pipe terminal such as a gas cock, and in particular, a connection state between a pipe inserted through a wall surface and a terminal device such as a gas cock. When fixed to the wall surface, the backing plate disposed in the wall surface can be opened and closed and can be inserted into the wall surface in a free state with a certain open state.

[Prior Art and Problems Thereof] In recent years, gypsum board is often used for indoor wall surfaces, and in such wall surfaces, indoor piping is arranged so as to pass through a space formed in the wall surface. . The pipe end of the pipe is projected from the opening formed in the gypsum board, and a terminal device such as a gas cock is fixed to this.

In the case of this method, there is an advantage that the indoor piping is buried in the wall surface, but since the strength of the gypsum board is insufficient, and because the flexible tube is adopted as the indoor piping, conventionally As shown in Fig. 6, a pipe terminal fixing tool (No. Shokai 63-146281) is used.

In this conventional device, an opening (H) having a sufficient size is formed in a gypsum board forming a wall surface (W), and a joint (20) is attached to a tip of a flexible tube (2) drawn from the opening (H). The gas cock (1) is connected through the ring (1), and the ring-shaped mounting plate (6) provided in the joint (20) is inserted into the space inside the wall surface (W) to face the back surface of the wall surface (W). Contact plate (4)
The gas cock (1) and the pipe terminal are fixed to the wall surface (W) by screwing and to each other with mounting screws (5) and (5) which are inserted through the opening (H).

In this conventional device, since the peripheral edge of the opening (H) of the wall surface (W) is sandwiched between the backing plate (4) and the mounting plate (6), the member forming the wall surface has a strength such as gypsum board. Even if it is insufficient, there is an advantage that the pipe terminal can be securely fixed.

However, in this conventional one, the backing plate (4) has a U-shape as a whole, and the whole is open (H).
Since it is larger than the above, it is necessary to perform a complicated operation while turning and to attach it to the inner surface of the wall surface (W), and the insertion work into the wall surface is troublesome.

The present invention has been made in view of the above points, and includes a flexible tube (2) arranged in a wall surface (W) and a terminal device such as a gas cock (1) connected to a piping terminal portion. Fittings (20)
The wall of the wall (W) is attached to the outer surface of the wall (W) by a mounting plate (6) and a back plate (4) attached to the back of the wall (W). In a pipe terminal fixing tool for fixing the pipe terminal to the wall surface (W) by sandwiching the peripheral edge of the opening (H), it is easy to insert the back plate (4) into the inner surface side of the wall surface (W). The task is to

[Technical Means] The technical means of the present invention taken to solve the above-mentioned problem is "a semi-circular arc portion of the backing plate (4) having an outer shape larger than the opening (H) and an inner peripheral shape smaller than this opening. And a straight portion extending tangentially from this as a substantially U-shaped plate body, and the abutting plate (4) is divided into a pair of substantially symmetrical plate-shaped halves at the center of the semicircular arc portion ( 41) and (42), and the end portions of the arcuate portions of the plate-like halves (41) and (42) are rotatably coupled to each other, and the plate-like halves are urged in a direction to open them. The spring (43) is inserted near the coupling fulcrum, and the plate-shaped halves (41) (42) are arranged so that the arcuate portions of the plate-shaped halves (41) (42) are continuous in a semi-circular shape as a whole in the maximum opened state. A stopper that sets the maximum opening angle of the body to a constant angle is arranged near the connection fulcrum. "

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

The backing plate (4) is composed of plate-like halves (41) (42) that are openably and closably coupled to each other, and in a state where no external force is applied,
It is a substantially U-shaped plate body as a whole, which is composed of a semi-circular portion and a linear portion extending tangentially therefrom.

In order to insert the plate-shaped pad plate (4) into the wall surface (W), it is folded at the connecting fulcrum of both halves. As a result, the tip ends of the linear portions of the plate-like halves (41) (42) are folded until they are in contact with each other. In this state, the whole becomes elongated and is inserted as it is from the opening (H). When the folding force is released in a state where the whole is located inside the wall surface, the initial state (maximum open state) is restored by the urging force of the spring (43). At this time,
In the vicinity of the joint fulcrum of the plate-like halves (41) (42), a stopper that keeps the maximum opening constant is provided, so that the plate-like halves (41) (42) (42) are provided in the set maximum open state. ), The arc-shaped portion is continuous in a semi-circular shape. The straight line portion is formed to extend in the tangential direction of the semi-circular arc portion. Since the inner peripheral shape of the backing plate (4) is composed of a semi-circular arc portion smaller than the opening (H) and a straight line portion extending tangentially therefrom, and the outer shape is larger than the opening (H), the peripheral edge of the opening (H). When it is attached to the back surface of the mounting plate (6) and is screwed to the mounting plate (6) on the outer surface side, the peripheral edge of the opening is sandwiched by both, and the terminal device integrated with the mounting plate (6) or a terminal device mounted on the wall surface ( W) will be fixed.

At this time, each plate-shaped half body is formed in a bent planar shape, and the connecting portion is connected so as to rotate on a plane parallel to the constituent surface of the backing plate (4). From
The tightening force when the mounting plate (6) and the contact plate (4) are screwed does not act directly on the connecting portion.

[Effects] The present invention having the above-described configuration has the following unique effects.

Insert the backing plate (4) from the opening (H) in the folded state,
When the folding force is released, it automatically returns to the unfolded state, so that the work of inserting the backing plate (4) into the wall surface (W) is simpler than the conventional one.

As a whole, the U-shaped backing plate is folded and inserted so that the tips of its straight parts are in contact with each other, and the arc-shaped part is opened so that it becomes a semi-circle after insertion, so the maximum width when folded is When the opening is small and the maximum opening, the contact can be made over a sufficiently wide range of the outer peripheral area of the opening (H). Therefore,
It is easy to handle and the degree of engagement with the peripheral edge of the opening (H) is sufficient. Further, when the backing plate (4) is screwed to the mounting plate (6) and mounted on the wall surface (W), the connecting portions of the plate-shaped halves (41) (42) forming the backing plate (4) are Since the tightening force by screwing does not act directly, even if the contact plate (4) is divided into two parts, it has sufficient strength.

Thus, the backing plate has good workability and sufficient strength.
