Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a connection structure of a rain gutter, and mainly relates to a connection structure of a gutter that connects an anchor and a downspout.

(Prior Art) Conventionally, in order to connect rain gutters, the connecting ends of the rain gutters to be connected to each other were fitted or joined together, and then the connecting portions were fixed with solder, adhesive, or the like.

(Problems that the invention aims to solve) Therefore, with the conventional connection method as described above, the connection work is time-consuming and the assembly work at the construction site is time-consuming, resulting in poor workability and the need for skilled workers. There was a problem that required .

(Purpose of the present invention) Therefore, the present invention has been made in view of the above-mentioned conventional problems, and is a connecting part of rain gutters that can easily connect two rain gutters without using solder or adhesive. The purpose is to provide structure.

(Means for Achieving the Object) In order to achieve this purpose, the present invention provides a connecting part structure having a concave locking part on the upper surface of the fitting side connection end of one of the rain gutters that are fitted and connected to each other. is formed, and a plurality of locking pawls are formed on the upper surface of the other adjacent rain gutter by making cuts at predetermined close pitches over the entire length in the longitudinal direction from the fitting side connection end. In order to achieve the intended purpose, the locking claws are provided in a row, and the locking claws located at the fitting side connection ends are locked to the locking portions formed on the one rain gutter. This is what I did.

(Function) When connecting rain gutters with the above configuration, when the fitting side connecting end of the other rain gutter adjacent to the fitting side connecting end of one rain gutter is fitted, the connecting end The locking pawl formed in the rain gutter contacts the edge of the top surface of the connection end of the one rain gutter, is pushed up against the elastic force of the locking pawl, and presses against the top surface of the connection end. while sliding. When the locking pawl reaches the concave locking portion formed at the connecting end of the one rain gutter, it is elastically engaged with the locking portion due to the elastic force of the locking pawl. be stopped.

(Example) Hereinafter, an example will be described in which the present invention is implemented as a connection part structure of a gutter that connects an anchor and a downspout as a rain gutter. 11 is an eaves gutter disposed along the eaves 12 of the building, and 13 is a water collector attached to fit on the lower surface of the eaves gutter 11 to collect rainwater flowing into the eaves gutter 11. An anchor 14 is fitted to the lower end of the water collector 13. Reference numeral 15 denotes a downspout disposed vertically along the wall 16 of the building, etc., and the downspout 15 and the anchor 14 are connected via a rectangular tubular pipe a, which collects water. Vessel 1
The rainwater collected in 3 is discharged to the ground through an anchor 14, a gutter a, and a downspout 15.

Note that the rain gutter in the present invention includes not only metal such as copper but also synthetic resin such as PVC.

The gutter a is composed of a gutter main body 17 and an elbow 18, and a fitting side connecting portion 17a at one end of the gutter main body 17 is fitted and fixed to a fitting side connecting end 14a at the tip of the anchor 14, The gutter body 17
The fitting side connecting end 18a at one end of the elbow 18 is fitted and fixed to the fitting side connecting end 17b at the other end, and the fitting side connecting end 18a at the other end of the elbow 18 (not shown)
is fitted into and fixed to the fitting-side connection end 15a at the upper end of the vertical gutter 15. The fitting side connecting end 14a of the anchor 14 has a step and is formed to have a slightly smaller diameter, and when the fitting side connecting end 17a of the nominal gutter main body 17 is fitted, the fitting side connecting end 14a of the anchor 14 is connected to the outer peripheral surface of the anchor 14. The outer circumferential surface of the gutter main body 17 is made to be on the same plane. Moreover, on the upper surface of the connecting end portion 14a,
Concave locking portion 1 that slopes downward in the insertion direction
9 are formed in pairs in the horizontal direction. A plurality of locking pawls 20 are provided in a row on the upper surface of the gutter main body 17 and are formed by cutting in a substantially U-shape at predetermined close pitches over substantially the entire length in the longitudinal direction. The locking claws 20 are bent so as to be inclined toward the inside of the gutter main body 17, and the locking claws 20 located at the fitting-side connecting end of the locking claws 20 are connected to the fitting-side connecting end of the anchor 14. The gutter main body 17 is connected to the anchor 14 by being elastically locked by a locking portion 19 formed on the anchor 14a.

Reference numeral 21 represents a vent hole formed by bending the locking claw 20 inward.

In the above embodiment, the structure of the connecting portion between the anchor 14 and the gutter main body 17 has been described, but this structure can also be applied to the connecting portion between the gutter main body 17 and the elbow 18.

(Effects of the present invention) As described above, according to the present invention, a concave locking portion is formed on the upper surface of the fitting side connection end of one of the rain gutters that are fitted and connected to each other. A plurality of locking pawls are provided in a row on the upper surface of the other adjacent rain gutter, which are formed by cutting at predetermined close pitches from the mating side connection end over the entire length in the longitudinal direction. The structure is such that the locking pawl located at the fitting side connecting end of these is locked to the locking part formed on the one rain gutter, so that the fitting side connecting end of one rain gutter is locked. The connection and fixation can be ensured simply by fitting the fitting-side connection end of the other rain gutter into the part. Therefore, the rain gutter can be easily installed without the need to use soldering or adhesives as in the past, and work efficiency at the installation site can be greatly improved.

Furthermore, according to the present invention, since a notch is made on the top surface of the rain gutter to provide a locking pawl, when cutting the rain gutter to the required length to match the building at the construction site, the cut point can be Since it can be easily cut by inserting scissors through the corresponding notch, the length can be easily adjusted. Conventionally, when cutting a rectangular cylindrical rain gutter to a predetermined length to match a building, etc. on site, a hole was generally drilled at the cut point using a tool, and then the tip of cutting scissors was inserted into the hole. However, in the present invention, the notch formed to provide the locking pawl can be used as a guide hole for the cutting scissors, which is extremely convenient.

Furthermore, since the vent formed by the above-mentioned notch functions to bleed air during drainage, rainwater flows smoothly in the rain gutter and can be drained quickly. Moreover, since the locking pawl is formed on the upper surface of the rain gutter, the appearance does not deteriorate.
