Abstract

PROBLEM TO BE SOLVED: To enable a piping connection part of a hot water toilet seat device to be easily held with fastness. SOLUTION: This clamp device is provided with an approximately C-shaped cross-section main body 12, which is made of a resin and formed with a hole 12a, an approximately C-shaped cross-section metallic clamp body 11, which is detachably fitted into the hole 12a via an opening 12b of the main body 12, and a cover body 17, whose base part 17a is pivotably connected to one side of the opening 12b and whose free end 17b is detachably locked to the other side thereof. In the clamp device, the piping connection part of an wet-area device such as the hot water washing toilet seat device allows the hole 12a and both the openings 12b and 14 of the clamp body 11 to undergo a snap action, and allows the free end 17b of the cover body 17 to be locked to the other side of the opening 12b.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp device used for a pipe connection in a hot water flush toilet seat device and other plumbing devices.

[0002]

2. Description of the Related Art As is well known, in a hot water flush toilet seat apparatus, a pipe connecting portion (a connecting portion between a branch tap and a water supply hose and a connecting portion between an operation panel body and a water supply hose) is provided inside one end of a pipe. In this embodiment, the end of the other pipe is fitted. However, when water flows from the former to the latter, the water pressure (particularly the water hammer) acts on the end face of the latter, and there is a fear that the latter may be pulled out from the former, so that the pipe connection portion must be held firmly. For this reason, conventionally, a common nut was screwed onto two pipes at the pipe connection part.

[0003]

However, since the above-mentioned warm water flush toilet seat device is mounted on a toilet installed in the toilet space, and the toilet space is small, it is difficult to screw the nut. Needless to say, improvement was requested.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus which can easily hold a pipe connection portion of a hot water flush toilet seat device easily.

[0005]

The first technical means taken to solve the above-mentioned technical problem is, as described in claim 1, "a resin having a substantially C-shaped cross section and a hole formed therein. A metal clamp body removably fitted into the hole through an opening of the main body and having a substantially C-shaped cross section;
A cover body having a base pivotally connected to one side of the opening of the main body and having a free end detachably locked to one side of the opening of the hole; The pipe connection part of the device makes the opening of both the hole and the metal clamp body perform a snap action, and the free end of the cover body is locked to the other side of the opening part of the main body. The clamping device. Is constituted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, a clamp device 10 includes a resin body 12 having a hole 12a having a substantially C-shaped cross section. Thus, the opening 12b of the hole 12a is defined between the pair of opposing elastic legs 12c, 12c, and the length of the narrow portion between the legs 12c, 12c is
It is set smaller than the diameter of a.

The main body 12 has a pair of slots 16 and 16 symmetrically formed with respect to the opening 12b. The ends of the slots 16 and 16 on the opening 12b side are formed as rods 12e and 12e. Has become.

The clamp device 10 further includes a metal clamp body 11 having a substantially C-shaped cross section. Metal clamp body 1
The opening 11b of the first hole 11a is defined between a pair of opposing elastic legs 11c.
The length of the narrow portion between 1c and 11c is set smaller than the diameter of the hole 11a.

The metal clamp body 11 has a pair of slots 30.
30 and a pair of slots 31
The protrusions 13 are symmetrically engraved, and protrude radially outward between the slots 30 (30) and 31 (31).
(13) is formed. The slots 31 are provided in the legs 11c.

A metal clamp body 1 having such a configuration
1 is a mode in which the leg portions 11c and 11c are pinched by hand and brought close to each other, that is, in a state where the diameter is reduced,
When the hand is released after passing through b and inserted into the hole 12a, the metal clamp body 11 expands and returns to the original state. Then, the protrusions 13 of the metal clamp body 11
Is engaged with the rods 12e of the main body 12, and the slots 12 of the main body 12 overlap with the slots 30 of the metal clamp body 11.

As shown in FIGS. 1, 2 and 3, a base portion 17a of a cover body 17 is integrally molded with one leg portion 12c of the opening 12b of the hole 12a of the main body 12. Thus, the base portion 17a is thin, and the cover body 17 is pivotally connected to the leg portion 12c on one side. On the other hand, the forked free end 17 of the cover body 17
3B, a protrusion 18 (only one is shown) is formed, and when the forked free end 17b of the cover body 17 is pivoted to be displaced in the direction of the leg 12c on the other side of the main body 12, FIG. As shown, the protrusion 18 is formed in the recess 15 formed in the main body 12.
, And the pipe connection portion is locked as described later.

An example of pipe connection will be described with reference to FIG. 4, FIG. 5, and FIG. A branch plug 2 which is a main part of the branch fitting 20
1 and the main body water supply hose 22 are connected to the main body water supply hose 2.
2 is inserted into the branch tap 21 after the O-ring (not shown) is covered with the O-ring (not shown). In order to hold this pipe connection firmly, the clamping device 10 is used.
Is used. That is, when the above-mentioned fitting is performed,
The flange 21a of the branch tap 21 and the flange 23a of the distal end portion 23 of the main body water supply hose 22 face each other and come into a surface contact state, that is, an engagement state. The opening 12b (the metal clamp body 11) of the main body 12 of the clamp device 10 shown in FIG.
The opening 14 is included in the opening 12b) on the flange 21a of the branch plug 21 and the flange 23a of the distal end 23 of the main body water supply hose 22, which are in the facing surface contact engagement state, that is, on the pipe connection portion. When the opening 12b of the main body 12 of the clamp device 10 is lowered thereafter, the flange 21a of the branch tap 21 and the flange 23a of the distal end 23 of the main body water supply hose 22 are opened 12b (opening 1).
After the snap action is performed in 4), the hole 12a
(Hole 11a), and as can be clearly understood in particular from FIGS.
1) is fitted inside. Then, in this fitted state, the cover body 17 is rotationally displaced toward the leg portion 12c on the concave portion 15 side,
If the projection 18 is fitted into the recess 15, it is locked,
The detachment from the main body 12 and the metal clamp body 11 becomes impossible.

The above-described operation merely locks the clamp device 10 in the open state shown in FIG. 2 by displacing and fitting the clamp device 10 in the direction of the pipe connecting portion, so that the pipe connecting portion is located in a small space. Can be easily performed without tools.

[0015] As shown in FIG.
6 is inserted into the distal end portion 24a of the water supply socket 24, and the flange 25 of the distal end portion 26a of the main body water supply hose 26 is engaged with the flange 27 on the distal end portion 26a of the main body water supply hose 26. Also, using the clamp device 10, the pipe connection portion can be held firmly in the above-described manner.

Although the specific examples of the present invention have been described above, the present invention is not intended to be limited to the above-described specific examples, and any method and apparatus that conforms to the gist of the present invention can be used. Such a thing may be used.

[0017]

As described above, according to the present invention,
Since the clamp device in the open state is merely fitted and locked in the direction of the pipe connecting portion, even when the pipe connecting portion is located in a small space, the mounting operation can be easily performed without tools.
