Abstract

<P>PROBLEM TO BE SOLVED: To provide an eaves gutter connecting device which absorbs the elongation of an eaves gutter without making the eaves gutter deteriorate a drainage capacity, even if the eaves gutter is further elongated by abutting on a stopper. <P>SOLUTION: In this eaves gutter connecting device, an eaves gutter joint is constituted by forming a drop-in step bottom surface portion 4 in the almost central portion of an eaves-gutter joint body 1 in which eaves-gutter connecting portions 3 and 3 are formed at both ends, and by forming a rainwater drainage drop-in port 5 in the bottom surface portion 4; and a guard tube 2, which is constituting by protrusively forming an eaves-gutter abutting and stopping piece 7, expanded and protruded upward and outward, on a fitting tube body 6, is detachably fitted into the drop-in port 5 of the eaves gutter joint from above, so that the piece 7 can be protruded into the eaves gutter joint. When the eaves gutters 9 and 9, which are connected to the connecting portions 3 and 3 at both the ends of the eaves gutter joint, are elongated due to heat, the eaves gutters 9 and 9 are blocked by the piece 7, so that the drop-in port 5 can be prevented from being blocked off, and so that the deterioration of the drainage capacity of the eaves gutters 9 and 9 can be prevented. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an eaves connecting device corresponding to an eaves extending by heat. More specifically, an eaves joint joint is formed by forming a bottom stepped portion at the substantially central portion of the eaves joint body with eaves connecting portions at both ends and forming a rainwater drainage outlet at the bottom of the dropped step. A guard cylinder, which is formed by protruding an eaves stop stopper projecting outwardly and projectingly from the fitting cylinder, is detachably fitted from above to the rainwater drainage outlet of the eaves joint. When the eaves connecting to the eaves connection part at both ends of the eaves joint is extended by heat, the eaves are stopped by the eaves stop. The present invention relates to an eaves connection device that prevents a rainwater drainage outlet from being shielded.

  Conventionally, the water collector shown by the following patent document 1 is known. That is, this water collector has a structure that cannot be attached to the water collector without cutting (cutting) the eaves, and the drainage performance is not hindered even if the eaves expands or contracts due to temperature changes. is there. That is, in this conventional water collector, even if the temperature of the eaves rises and the eaves elongates, it hits the stopper and does not reach the drain outlet of the water collector, so that the drainage performance is not hindered.

  However, the elongation due to the temperature of the eaves is not a force to stop when it hits the stopper, but elongates until reaching the elongation due to the temperature. In the case of this conventional water collector, when the eaves hits the stopper and further elongates, the eaves is considered to deform along the stopper. Since the stopper of this conventional water collector is tapered upward, it is considered that the eaves deforms upward along the stopper.

However, when the eaves deforms upward along the stopper, the drainage ability from the eaves into the water collector is hindered. In this sense, this conventional water collector is not sufficient. In general, when constructing eaves, the degree of elongation due to temperature is predicted according to the season, that is, when constructing in winter, it is predicted that it will grow greatly in the summer, but it is sufficient due to the lack of experience at the construction site of the contractor It often happened that it was not.
Japanese Patent Laid-Open No. 9-25687 (Summary, FIG. 1)

  The present invention considers the shape of the stopper of the water collector in the above conventional example, and even when the eaves is further extended by the stopper, the eaves connection device absorbs the extension without reducing the drainage capacity. The issue is to provide.

  In order to solve the above-mentioned problem, an eaves joint connection device according to the present invention forms a stepped bottom portion at a substantially central portion of an eaves joint joint body formed with an eaves joint connection at both ends, and at the dropped step bottom portion. A rainwater drainage outlet is formed to form an eaves joint, and a guard cylinder formed by protruding an eaves stop stopper projecting upward and outward on the fitting cylinder is dropped into the rainwater drainage of the eaves joint. When the eaves connected to the eaves joints at both ends of the eaves joint are stretched due to heat, the eaves contact stop is projected into the eaves joint. When the eaves are prevented by the stopper and further elongate, the eaves bends downward along the eaves stop and absorbs the extension.

  The eaves ridge connecting device according to claim 1 is configured so that the guard tube is formed by projecting eave ridge stoppers projecting upward and outwardly on the fitting cylinder, so When the eaves connected to the connecting part is extended by heat, the eaves are blocked by the eaves holding piece, and when further elongating, the eaves are bent downward along the eaves holding piece. In order to absorb the elongation of the eaves and bend downward, the drainage capacity of the eaves is not reduced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a partially cutaway perspective view of an embodiment of the eaves connecting device of the present invention, FIG. 2 is a partially cutaway perspective view of the embodiment shown in FIG. 1, and FIG. 3 is an eaves view of the embodiment shown in FIG. It is a partially notched perspective view which shows the state which connected. 1 and 2, reference numeral 1 denotes an eaves joint body, and 2 denotes a guard cylinder.

  The eaves joint body 1 is formed with eaves connection portions 3 and 3 at both ends, a drop bottom portion 4 is formed at a substantially central portion, and a rainwater drainage outlet 5 is formed in the drop step bottom portion 4. The rainwater drainage outlet 5 has a screw on the inner surface, and the guard cylinder 2 can be detachably attached thereto.

  The guard cylinder 2 is formed by projecting and forming an eaves-holding stopper piece 7 projecting upward and outward from the fitting cylinder 6, and a screw that is screwed to the rainwater drainage outlet 5 on the outer surface of the fitting cylinder 6. It has a part. An eaves-holding stop piece 7 of the guard cylinder 2 is formed on the fitting cylinder 6, and the eaves-holding stop piece 7 is formed to project upward and outward, and the upper end is coupled by a holding ring 8. ing.

  The holding ring 8 connects the eaves-holding pieces 7 to each other to increase the overall strength. The reason why the eaves-holding piece 7 is formed so as to expand outward is to guide the eaves-edge end downward when the eaves elongates and hits the eaves-holding piece 7.

  As shown in FIG. 3, the eaves joint connecting apparatus using the eaves joint is first fitted with a fitting cylinder 6 of the guard cylinder 2 detachably fitted to the rainwater drainage outlet 5 of the eaves joint main body 1. Specifically, it is screwed with a screw on the inner surface of the rainwater drainage outlet 5 and a screw on the outer surface of the fitting cylinder 6.

  Next, the eaves eaves 9 and 9 are attached to eaves eaves connection portions 3 and 3 formed at both ends of the eaves eaves joint body 1 respectively. In this case, the eaves 9 and 9 are connected not in a single line but in a disconnected state. This is because the eaves-holding stop piece 7 of the guard cylinder 2 is formed so as to expand upward and outward, so that it cannot be made through.

  In this eaves rod connecting device, even if the eaves rods 9 and 9 are extended, they hit the eaves rod stoppers 7 of the guard cylinder 2. When further elongating, the eaves eaves 9 and 9 are guided by eaves eaves-stopping pieces 7 formed to project outward and outward. In this case, since the eaves-eating stop piece 7 is formed so as to expand upward and outward, the ends of eaves eaves 9 and 9 are guided downward. For this reason, the drainage capacity of the eaves 9 and 9 into the eaves joint is not reduced.

  Further, the eaves-holding stop piece 7 also serves to prevent dust, and the fitting cylinder 6 of the guard cylinder 2 is detachably fitted to and attached to the rainwater drainage outlet 5 of the eaves-joint body 1. Therefore, it is possible to easily remove dust.
