Description

[Detailed explanation of the invention] Horizontal rain gutters that are generally attached to roof structures have traditionally been made of galvanized iron plates, steel plates, or plastics with an approximately semicircular or U-shaped cross section, and their service life has been shortened in normal times. Depending on the maintenance status, the lifespan of a typical house is 30 to 30 years.
Currently, they require replacement approximately every 7 to 8 years, 20 to 24 years, and 6 to 8 years, respectively.

Moreover, when connecting the gutter to each other, lap lining soldering is commonly used for those made of galvanized iron plates and steel plates, and for gutter made of resin, stepped lap gluing is used as a connecting means. It has become common knowledge.

However, in addition to the distortion of the gutter itself due to the impact of strong wind and rain or fallen leaves, etc., due to the inherent structural fragility of its attachment to the roof body, these joints often become distorted or broken. The current situation is that the intended purpose of water flow cannot be achieved before the end of its service life.

Recently, horizontal gutters made of light alloy extruded materials have been developed, and it is desirable that they have greater resistance to weather and climate, and that the shape retention and strength of the horizontal gutters themselves have been improved. When connecting, soldering, gluing, welding, etc. are practically impossible or extremely difficult due to the material and the work must be performed at a high place. The palliative method of mechanically friction-connecting the backing plates by making them come into contact with each other in a biased manner does not provide sufficient connection strength and leakage prevention effects, and this work is carried out only by specialized craftsmen working at heights. had no choice but to rely on the skilled work of

Therefore, it is easy to connect the gutter made of such standardized profiles,
There is a strong desire to develop a connecting member that is reliable and can be used even by those without specific skills, thereby fully demonstrating the inherent characteristics of a horizontal gutter made of profiled material.

In addition, it is possible to cope with and compensate for the thermal expansion of the gutter due to solar heat, which is the fate of gutter exposed to direct sunlight.In other words, it has a structure that allows relative movement of the gutter between the connecting devices, and completely prevents leakage of running water. It is possible to guarantee a service life of more than 3 times, which was completely unachievable with conventional structures, and to maintain an elegant appearance. SUMMARY OF THE INVENTION An object of the present invention is to provide a gutter connection device that can be connected in a horizontal manner.

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view showing how the horizontal gutter connecting device according to the present invention is installed, in which a short horizontal gutter 2 is connected to a receiving gutter 1 installed under the eaves of a house, and a long horizontal gutter 3 is connected to the end of the gutter. A predetermined interval (indicated by the broken line in the figure) using the coupling device 4 according to the present invention.
They are connected in a butt-like manner.

The receiving gutter 1 is attached with a chain for rainwater drainage, such as the one shown at 5, for example.

The gutter shown in this figure has a substantially semicircular main body, which is the object of the embodiment of the present invention.

FIG. 2 is an assembled perspective view showing the configuration of an embodiment of the connecting device for a horizontal gutter according to the present invention. The main components are an inner plate 7 made of an extruded aluminum alloy material which is pivotally connected to the outer plate at the upper end, and an elastic body 8 attached to the inner surface of the outer plate.

As shown in FIG. 1 and later-described FIGS. 3 and 4, the horizontal gutter 3 to which the horizontal gutter connection device of the present invention is applied has a main body 3a having a semicircular cross-sectional shape, and a main body 3a extending outward from both outer ends. It is integrally provided with a winding part 3b which protrudes from the top and is substantially hook-shaped and opens inward.

The outer plate 6 and the inner plate 7 of the coupling device are configured to sandwich and fasten the horizontal gutter which is disposed abutting against each other with a predetermined interval between them via an elastic member 8.

As shown in detail in FIG. 2, the outer plate 6 protrudes outward at both opening ends, has a substantially hook-shaped cross section, opens inward, and is engageable with the winding portion 3b of the horizontal gutter. It consists of a main body 6a having a winding engaging portion 6b.

One outer end of a substantially U-shaped inner plate main body 7a is pivotally connected to one outer plate winding engaging portion 6b by a shaft 9 on one of the winding portions 3b.

The winding engagement portion 6b of the outer plate on the side opposite to the side where the inner plate 7 is pivotally attached to the outer plate 6 is cut out at the center in the width direction of the outer plate, and a beak-shaped hook with a U-shaped cross section is provided in this part. A tool 14 is pivotally mounted at its proximal end by a shaft 13.

As is clear from the figure, the hook 14 has a shape that is curved toward the inner plate 7 from the center of its inner surface in the longitudinal direction to its tip.

A pair of inward protrusions 10 are provided at the upper edge of the inner plate 7 on the side opposite to the side pivoted to the outer plate 6 and are opposed to each other in the widthwise center of the inner plate. , the hook is the tool 14
A wheel 12 engageable with the shaft 11 is pivotally supported by the pivot shaft 11 .

The mounting procedure of the horizontal gutter coupling device according to the present invention is as shown in FIGS. 3 and 4. First, in FIG. The inner plate is engaged along the line engagement portion 6b and the main body 6a, and the inner plate is connected to the main body 3 of the horizontal gutter using the pivot 9 with the outer plate as a fulcrum.
It is pressed against a.

In this state, the wheel 12 at the outer end of the inner plate is oriented within the U-shaped cross section of the hook 14 which is pivotally supported by the outer plate winding engaging portion 6b.

Here, as shown in FIG.
By surrounding it counterclockwise around the wheel 12, the wheel 12 comes into contact with the inner surface of the curved part of the hook 14 and rotates, and the wheel 12 reaches the center of the hook 14, and the hook 14 and the wheel 12 rotate. The wheel 12 is reliably engaged, and the outer plate 6 and the inner plate 7 firmly connect the gutter with an elastic body interposed between both surfaces thereof.

Since the outer and inner plates are made of relatively thin aluminum alloy extrusions, they themselves have considerable elasticity, and by giving the inner plate a curvature greater than that of the gutter in its free state, Together with the elastic effect of the interposed elastic body, the adhesion with the horizontal gutter can be significantly improved.

Moreover, the desired purpose can be achieved very easily in the fastening operation by a single action operation in which the gutter connecting portion is sandwiched between the inner and outer plates and then the hook is rotated.

As described above, since this invention has the above-mentioned configuration, a beak-shaped hanging tool with a U-shaped cross section that is pivotally supported on the upper end of the outer panel and an engagement shaft of the white board can be used to connect the white board, horizontal gutter, and When using a horizontal gutter device that overlaps the outer panels, the inner panel, the horizontal gutter, and the outer panel can be strongly pressed and tightly engaged, and the horizontal gutter can be easily installed and removed, and there is no space between the inner panel and the outer panel. Since the waterproof elastic body is interposed, it is possible to completely prevent water from leaking from the connection part of the horizontal gutter, and the engagement shaft of the inner and outer panels, the engagement axis of the white panel, and the beak shape of the U-shaped cross section of the outer panel can be completely prevented. Since the horizontal gutter is connected by a single-action operation using the locking action of the hook, the horizontal gutter connecting operation at high places can be performed extremely safely, reliably, and easily.

In addition, this can be achieved without requiring advanced technology, and it can also compensate for thermal deformation due to solar heat, making it particularly possible to significantly contribute to the performance of gutter made of extruded aluminum material, which originally has a long service life.
