Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pipe cover joint used for connecting pipes such as an air conditioner and a water heater and a pipe cover such as a gutter pipe arranged along an inner wall surface or an outer wall surface of a building, Particularly, it relates to a pipe cover joint that can be easily attached during construction.

[0002]

[Prior Art]

 In a conventional pipe cover joint, for example, as disclosed in the pipe support tool (hereinafter referred to as pipe cover joint) described in Japanese Utility Model Laid-Open No. 1-169685, a support having a substantially U-shaped cross section is used. The tool body (hereinafter, support tool) and the pipe support part (hereinafter, presser tool) are connected to the screw holes provided at the tip of the side plates, while the support tool and the presser tool are fixed by screws to form a substantially tubular shape. There is something to do. Here, in the pipe cover joint in the above publication, in order to maintain the communication between the presser tool and the screw hole in the support tool at the time of screwing, a fitting that engages with the connecting edge of the presser tool and the support tool is engaged. It has a mating protrusion and an engaging groove.

[0003]

[Problems to be solved by the device]

 However, in the case of the pipe cover joint, if the screws are left unscrewed, the engagement force between the engagement protrusion and the engagement groove is weak, so the screw holes are not only misaligned, but also the presser and the support are not supported. There was a problem that the tool came off and the work clamp was dropped during the work. In addition, when fixing the pressing tool of the pipe cover joint to the support tool or detaching it from the support tool, two screws must be attached and detached, which causes a problem that the work is troublesome.

Therefore, the present invention is a pipe cover joint devised to solve the above-mentioned problems of the conventional products, and the object of the present invention is to once connect the presser foot and the support tool. An object of the present invention is to provide a pipe cover joint that can be easily removed without screwing and that can fix the support and the presser with a single screw.

[0005]

[Means for solving the problem]

 The present invention has been devised in view of the above, and is a pipe casing formed into a substantially tubular shape by engaging the U-shaped tip portions of a support tool and a presser tool, each of which has a substantially U-shaped cross section. In the bar joint, a hinge portion is provided at one of the U-shaped tip portions so as to openably and closably connect the support tool and the holding tool, and the other tip end is locked to each other. And a locking recess, respectively, and screw holes communicating with each other are formed in the locking projection and the locking recess, respectively.

Here, the hinge portion connects the support tool and the presser tool so as to be openable and closable, and once engaged, any one of them can be rotated to rotate the support tool and the presser tool. Are engaged so as not to come off. In addition, the hinge portion may use a conventionally used hinge mechanism, and it goes without saying that one of the male and female of the paired hinge mechanism may be provided on either the support tool or the presser tool. Is.

Further, as long as the locking projection and the locking recess can satisfy the mechanism of the hinge portion, any one can be locked as long as they engage with each other at their engaging surfaces. Needless to say, the locking projection may be provided on either one of the support tool and the pressing tool, or the locking recess may be provided on the other.

[0008]

[Action]

 According to the present invention, a hinge portion is provided at one tip of the U-shaped tip portions of the support tool and the holding tool that form a joint for a pipe cover and are formed in a substantially U-shaped cross section, while the other tip portion is provided. Since the locking projections and the locking recesses are provided near the screw holes of the support tool, it is possible to easily engage the holding tool with the support tool after the pipe is housed in the substantially U-shaped cross section of the support tool. Even if the support tool and the pressing tool are engaged with each other with only one screw, the engagement is not inadvertently released.

[0009]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is an explanatory view showing an embodiment of a pipe cover joint according to the present invention, and FIG. 2 is an enlarged view of the hinge portion of FIG. 1 seen from the longitudinal direction of the pipe cover joint.

The pipe cover joint shown in this embodiment is formed in a substantially tubular shape by engaging the U-shaped tip portions of the support tool 1 and the presser tool 2 each having a substantially U-shaped cross section. A wall mounting hole 11 is provided substantially in the center of the support 1 for mounting the pipe cover joint on the wall surface of the building to which the pipe is mounted. In addition, an end face is formed at the tip end portions 11, 12, 21, 22 to which the support tool 1 and the presser foot 2 are engaged, and one of the tip end portions to be engaged is formed. On the outer peripheral surface side of the tip portions 11 and 21, there are provided hinge portions 3, 3 and 3 which rotate once fitted, but do not easily separate, and further on the inner peripheral surface side of the other tip portions 12 and 22. Is provided with a locking projection 41 and a locking recess 42 that come into contact with each other when the support tool 1 and the pressing tool 2 are locked.

The locking projection 41 and the locking recess 42 are provided with screw holes 41a and 42a which communicate with each other when the support tool 1 and the pressing tool 2 are locked. Although not shown, a screw (not shown) can be inserted into the screw hole 42 on the outer peripheral surface side of the screw hole 42 of the retainer 2 and the head of the screw is locked to the retainer 2. Is provided.

Here, in the pipe cover joint according to the present embodiment, the pipe covers are connected together with the pipes from the state shown in FIG. 1 by the following actions.

From the state shown in FIG. 1, the hinges 3, 3, 3 are engaged to engage the retainer 2 with the support 1, and as a result, the hinge 3 is viewed from the longitudinal direction of the pipe cover joint. To the state shown in FIG. In addition, in the actual work of attaching the pipe cover, the support tool 1 is fixed to the wall surface of the building where the pipe is installed by screws (not shown) in advance, and the pipe cover is provided inside the support tool 1 in a substantially U-shape. Are installed while interiorizing air-conditioning piping and the like.

Next, the presser foot 2 is rotated around the hinge portion 3 as a rotation axis so that the tip portions 12 and 22 on the opposite side of the hinge portion 3 are engaged with each other, and the tip portions 12 and 22 are connected. The locking projection 41 and the locking recess 42 in the vicinity are locked, and the screw holes 41a and 42a at the tips of the locking projection 41 and the locking recess 42 are communicated with each other. Then, a screw (not shown) is inserted from the screw hole 42a toward the screw hole 41a to fix the presser tool 2 and the support tool 1.

In the above-described embodiment, the pressing tool 2 can be easily rotated with respect to the support tool 1 even after the hinge portion 3 is once engaged, thereby connecting the pipe cover. This has the effect of making it easier to do the work.

[0016]

[Effect of the device]

 According to the present invention, a hinge is provided at one tip of the U-shaped tips of the support and the retainer to openably and closably connect the support and the retainer, and the other tips are engaged with each other. Since the locking projections and the locking recesses for stopping are provided and screw holes communicating with each other are formed in the locking projections and the locking recesses, if the pressing tool and the support tool are once connected, Even if it is not screwed, it does not easily come off, and the effect is that the support and the retainer can be fixed with a single screw.
