Description

[Detailed description of the invention] "Industrial application field" This invention relates to the mounting structure of rain gutters attached to buildings and their supporting metal fittings.

``Prior Art'' Conventional rain gutters are made of tin plate, plastic, etc., and are usually attached to the eaves of houses using mounting brackets.

``Problems to be solved by the invention'' The objective is to obtain a mounting structure for a rain gutter and its supporting metal fittings that can be easily installed and removed.

``Means for solving the problem'' A raised part is provided on both sides of the bottom, an edge is formed above them that curves inward, and the end of one edge curves inward to form a U-shaped part. The other edge curves inward to form a rain gutter with a descending part, an obliquely upward part, and an inward piece at one end of the flat plate part, forming an inverted U-shaped part pointing vertically upward, and the other end. is characterized in that locking portions are formed that face perpendicularly downward and diagonally upward, one of which is engaged with a support fitting having a fitting protrusion at its tip, and the other is fitted and fixed. The installation structure of the rain gutter shall be

``Function'' Utilizing the elasticity of its constituent materials, the rain gutter can be easily installed and removed by hooking one end to a separately prepared rain gutter support metal fitting and fitting the other end into place. .

Embodiment FIG. 1 shows the installation structure of a rain gutter according to this invention, and a part of the rain gutter A is shown in cross section. This rain gutter A is made of aluminum plate, for example.
It is formed by roll-homing a stainless steel plate or the like, or from a plastic plate, and has an appropriate length.Bottom 1 has rising parts 2 and 2' on both sides, and an edge above them. 3,
3' is formed. Among these, the edge 3 is bent inward and its end becomes a U-shaped part 4, and one edge 3' is bent inward and its tip becomes a descending part a.
Furthermore, it has a structure in which an oblique upper part b is formed, and an inwardly directed part c is formed at the tip thereof.

Note that the bent part on the way from the descending part a to the obliquely upper part b is formed into a somewhat rounded curved part R to provide elasticity, and the tip of the inward piece c is connected to the upper side 3a of the edge 3'. They are formed in a separated state so that a gap S is created between them.

On the other hand, B is a supporting metal fitting for attaching this rain gutter A, and is formed by cutting an integrally molded aluminum extrusion molding into a certain width. an inverted U-shaped portion 6 facing vertically upward on the side corresponding to the edge 3;
, and the other end (the side corresponding to the edge 3') is formed with a locking portion 7 that faces perpendicularly downward and diagonally upward. A fitting protrusion d having a substantially triangular cross section, for example, is provided at the tip of the locking portion 7.

A mounting hole is bored in the center of this flat plate portion 5.

To attach this rain gutter A to a building, as shown in the figure, pass the male screw e drilled in the drive fitting C through the aforementioned mounting hole, fix it with nuts f and f', and attach it to the gable plate of the building. Type it in.

Next, the operation of engaging the edges 3, 3' of the rain gutter A with the supporting metal fitting B of this invention will be described.

When engaging the rain gutter A with the support fitting B, the U-shaped part 4 of one edge 3 of the rain gutter A is connected to the support fitting B.
By hooking it onto the inverted U-shaped part 6 on one side, and then fitting the edge 3' of the other end into the locking part 7 of the support bracket B, it can be easily and quickly done by hand. These can be engaged. At that time, support bracket B
When the edge 3' consisting of the descending part a, the diagonally upper part b, and the inwardly facing part c of the rain gutter A is fitted into the space H formed by the locking part 7 of the rain gutter A so as to be pressed from above, According to the shape of the locking part 7 of the support fitting B, this edge 3' automatically fits into it, thereby ensuring sufficient fixation and completing the installation and fixation of the rain gutter.

At this time, a gap s' is maintained between the locking part 7 and the edge part 3', and there is an inclination, and the edge part 3' has elasticity due to the curved part R between the descending part a and the obliquely upper part b. Since the inward C end is a free end, the edge 3' can be fitted very smoothly along the locking part 7. In other words, they are easy to fit together, and after they are fitted, the spring force of the edge 3' causes them to spread inside the space H, making them difficult to come off.On the other hand, when they are removed, the ends of the inward pieces c are free. It's curved so it's easy to remove.

Note that the support fittings B are pieces having a constant width as described above, and are arranged at appropriate intervals.

``Effects'' When attaching a rain gutter to a supporting metal fitting, this idea first hooks one edge, then fits and secures the other edge, making it easy to install.
The sloping surface and some gap formed between one edge of the rain gutter and the locking part of the support fitting facilitate fitting, and the tip of the inward piece of this edge is free. By providing a gap between the end and the upper edge, even if there is a dimensional error in the rain gutter itself, it can be absorbed in the fitted state.

Of course, there are many advantages in that there is no need for any screws or the like for installation, and that it can be easily removed for repair, repair, or cleaning.

Claims (1)

[Scope of utility model registration request] A raised portion is provided on each side of the bottom, and an inwardly curved edge is formed above them, the end of one edge is curved inwardly to form a U-shaped portion, and the other edge is curved inwardly. The rain gutter is bent so that its tip becomes a descending part, an obliquely upward part, and an inward piece. One end of the flat plate part forms an inverted U-shaped part pointing vertically upward, and the other end points perpendicularly downward. 1. A rain gutter mounting structure characterized in that a locking part facing diagonally upward is formed, one of which is engaged with a support fitting having a fitting protrusion at its tip, and the other is fitted and fixed.
