Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an eave gutter joint for longitudinally connecting a pair of eaves gutter.

[Background Art] There are eaves and gutter joints as shown in Fig. 4. This has a fitting groove 2 recessed on the inner periphery of the joint body 1, a fitting protrusion 4 protruding from the outer periphery of the inner holding plate 3, and the fitting protrusion 4 is fitted into the fitting groove 2. In this state, the fitting protrusion 4 is fixed to the fitting groove 2 by caulking the rivets 14 at both ends of the inner holding plate 3, so that the inner holding plate 3 is attached to the inner circumference of the joint body 1.
It is designed to be fixed. By inserting and fitting the end of the eaves gutter 5 into the insertion gap 6 formed between the inner circumferential surface of the joint body 1 and the outer circumferential surface of the inner holding plate 3, the pair of eaves gutter 5 The end portion is fixed within the joint body 1 to make the connection. In this device, in order to form an insertion gap 6 between the joint body 1 and the inner holding plate 3, a fitting protrusion 4 is provided on the inner holding plate 3 so as to protrude from the inner holding plate 3.
In order to improve the fixing strength of the joint body 1, the fitting protrusion 4 is fitted into the fitting groove 2. However, the problem with eaves gutter joints formed in this way is that the inner retaining plate 3 is supported by the fitting protrusion 4 in a state close to line contact with the joint body 1, which causes inclination. That's easy. That is, the opening width of the insertion gap 6 is set to be approximately equal to the thickness of the eaves gutter 5 in order to increase the strength of insertion and fitting of the eaves gutter 5. When inserting and connecting the ends of the gutters 5, 5, if the end of one of the eaves gutters 5 is inserted into the insertion gap 6 of the other, the one of the insertion gaps 6 will close to the eave as shown in FIG. 5b. The gutter 5 acts to widen the width, and as a result, the inner pressing plate 3 tilts around the fitting protrusion 4, and the opening width of the other insertion gap 6 becomes narrower. Therefore, it becomes extremely difficult to insert the eaves gutter 5 into the other insertion gap 6.

[Purpose of the invention] The present invention has been made in view of the above points, and provides an eaves gutter joint that can connect eaves gutter without making the insertion work of the eaves gutter difficult. The purpose is to

[Disclosure of the invention] Thus, the eaves gutter joint according to the present invention has a fitting groove 2 in the circumferential direction recessed in the inner surface of the joint body 1 having a substantially C-shaped cross section with an open top surface, and a substantially C-shaped cross section with an open top surface. A fitting protrusion 4 in the circumferential direction is provided on the outer surface of the C-shaped inner holding plate 3, and the fitting protrusion 4 is fitted into the fitting groove 2 in a shallow or deep manner, so that the fitting protrusion 4 is inserted into the inner periphery of the joint body 1. An insertion gap 6 in which the holding plate 3 is arranged and the end of the eave gutter 5 is inserted between the inner circumferential surface of the joint body 1 and the outer circumferential surface of the inner holding plate 3.
The fitting protrusion 4 is fixed in the fitting groove 2 at one circumferential end of the inner holding plate 3, and the engagement piece 7 is fixed at the other circumferential end of the inner holding plate 3. It is characterized in that the engaging piece 7 is engaged with the engaged piece 8 provided on the joint body 1, and the width of the insertion gap 6 is The above object is achieved by making it possible to insert the eaves gutter 5 in an expanded state.The present invention will be described in detail below with reference to examples.

Fig. 1 shows an embodiment of the present invention, in which a joint body 1 is formed of a metal plate such as a copper plate or a steel plate and has a substantially C-shaped cross section with an open top surface, and has ear fitting pieces at both ends. 13, 13 are extended. The central part of the joint body 1 is recessed with a semicircular cross section so that a circumferentially long fitting groove 2 opens toward the inner surface when bent. 13 has a hook-shaped engaged piece 8 extending therefrom. In addition, the inner holding plate 3 is similarly formed of a metal plate and has a substantially C-shaped cross section with an open top surface, and a fitting protrusion 4 that is long in the circumferential direction by bending is formed in the center of the inner holding plate 3. It is provided so as to protrude outward toward the outside with a semicircular cross section. The protruding dimension of the fitting protrusion 4 is set larger than the depth dimension of the fitting groove 2, and a hook-shaped engagement piece 7 is provided at one end of the inner holding plate 3.
is extended. Then, the fitting protrusion 4 is fitted into the fitting groove 2, and the inner holding plate 3 is disposed inside the joint body 1. At this time, one end of the inner holding plate 3 is inserted as shown in FIG. 3a. With the fitting protrusion 4 fitted into the fitting groove 2, it is fixed by caulking with rivets 14 or screwing. The other end of the inner holding plate 3 is not fixed with rivets 14 or the like, and the fitting protrusion 4 is not fitted into the fitting groove 2 of the joint body 1 as shown in FIG. 3b. . Therefore, due to the elastic deformation force of the inner presser plate 3, the fitting protrusion 4 can be fitted into the fitting groove 2 at the other end of the inner presser plate 3 in a shallow or shallow manner.

However, in the eaves gutter joint formed in this way, the opening width of the insertion gap 6 formed between the joint body 1 and the inner holding plate 3 is as shown in FIG. At the end of the stop, the width _d1 is narrow, being approximately the same as the thickness of the eaves gutter 5, and the width _d2 becomes wider as it goes to the other end. In this state, the end of the eaves gutter 5 is inserted into one of the pair of insertion gaps 6, 6, and the lug 12 of the eaves gutter 5 is fitted into the lug fitting piece 13 of the joint body 1. However, since most of the opening width of the insertion gap 6 is wider than the thickness of the eaves gutter 5, the opening width of the insertion gap 6 is not forced wider by the eaves gutter 5.
The inner holding plate 3 is not tilted. Therefore, the groove width of the other insertion gap 6 is not narrowed, and the eaves gutter 5 can be smoothly inserted into the other insertion gap 6. After inserting the pair of eaves gutters 5 into the respective insertion gaps 6, 6 in this way, insert the engaging piece 7 of the inner holding plate 3 into the engaged piece 8 of the joint body 1 as shown in Fig. 2b. When the inner pressing plate 3 is drawn toward the joint body 1 so that the fitting protrusion 4 is deeply fitted into the fitting groove 2 by engagement, as shown in Fig. 2b and Fig. 3c. The opening width of the insertion gap 6 is equal over the entire length, and the end of the eaves gutter 5 is held within the insertion gap 6.

[Effect of the invention] As described above, in the present invention, the fitting protrusion is fixed in the fitting groove at one circumferential end of the inner holding plate, and the fitting protrusion is fixed in the fitting groove at the other circumferential end of the inner holding plate. Since the engaging piece is provided at the end and is engaged with the engaged piece provided on the joint body, when the engaging piece is not engaged with the engaged piece, the inner pressing plate and the joint are The opening width of the insertion gap formed between the inner holding plate and the main body can be made wider from one end of the inner holding plate to the other end, and as a result, the end of the eaves gutter can be narrowed between the pair of insertion gaps. When inserting into one of the insertion gaps, the opening width of most of the insertion gap can be made larger than the thickness of the eaves gutter, and the opening width of the insertion gap is expanded by the eaves gutter. This prevents the inner holding plate from tilting, and prevents the opening width of the other insertion gap from narrowing and making it difficult to insert the eaves gutter. .
