[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter joint used for connecting an eaves gutter and an elbow or a gutter attached to buildings such as general houses, factories and warehouses.

[0002]

2. Description of the Related Art Conventionally, a gutter joint used to connect an eaves gutter and a gutter attached to a building such as a general house, a factory or a warehouse is used when rainwater flows from the eaves gutter to an elbow. It is used, and a typical shape is Japanese Patent Laid-Open No.
A gutter joint described in Japanese Patent No. 248046 is known.

In the gutter joint described in Japanese Unexamined Patent Publication No. 5-2448046, a water-side insertion tube portion and a water-side insertion tube portion are divided by a collar portion to form a tubular joint body, and the water-side insertion tube portion is formed. The opening edge is formed in a taper shape, and a waterproof packing material is provided on the outer periphery in the middle of the water upper insertion tube so that the water upper insertion tube is slidable on the water upper downpipe. Since the underwater insertion tube portion is inserted and fitted into the vertical gutter to connect the vertical gutter, expansion and contraction in the axial direction of the vertical gutter can be absorbed.

Furthermore, a sluice installed between an elbow connected to an eaves gutter attached to a building such as a general house, a factory or a warehouse and a vertical gutter is a rain gutter which passes rainwater from the eaves trough to the vertical gutter. A gutter described in Japanese Utility Model Laid-Open No. 3-128127 is known as a typical shape used when pouring.

The gutter described in Japanese Utility Model Laid-Open No. 3-128127 is slidably fitted with a water side tubular member and a water underside tubular member to form a gutter main body, and can be bent at an end of the gutter main body. It is equipped with such a bellows-like connecting tube, and when the eaves gutter and the vertical gutter are connected via this flume, the expansion and contraction of the eaves gutter caused by the temperature difference in summer and winter is almost orthogonal to this eaves gutter. The attached sluice is absorbed by a flexible bellows-shaped connecting tube.

[0006]

However, Japanese Unexamined Patent Publication No.
In the gutter joint described in Japanese Patent No. 248046, when only the vertical gutter is connected, the water side insertion part is slidably inserted into the water side vertical gutter, so that the axial direction caused by the temperature difference in the summer and winter of the vertical gutter. It can absorb expansion and contraction, which is convenient, but when connecting the eaves gutter and the vertical gutter through this gutter joint, elbow and called gutter, etc.
As eaves gutter expansion and contraction caused by temperature differences in summer and winter may apply force in the direction perpendicular to the vertical axis of the gutter, this expansion and contraction in the direction perpendicular to the axis cannot be absorbed by this gutter joint.
Elbows and eaves gutters may be damaged. This is shown in FIG.
-It demonstrates, referring FIG. In FIG. 3, the eaves gutter 101
Is connected to one end of an elbow 103 via a drain joint 102, the other end of the elbow 103 is connected to one end of a sluice gutter 104, and the other end of the sluice gutter 104 is connected to a downspout 105. Has been done.

The eaves gutter 101 due to the temperature difference between summer and winter
Expands and contracts in the direction of the arrow along the eaves. Then, the force which tries to rotate the call gutter 104 around the down gutter 105 acts. As a result, the elbow 103 and the drain joint 102
A force to rotate the elbow 103 acts on the connection portion with and, as shown in FIG. 4, a crack 106 may enter the elbow 103 and the drain joint 102 or the like, and the elbow 103 and the trough joint 102 may be damaged. .

The gutter described in Japanese Utility Model Laid-Open No. 3-128127 is used when connecting an elbow and a vertical gutter, and since the main gutter body is formed so as to be slidably fitted, a gutter shaft. The expansion and contraction in the direction can be absorbed, and the bellows-shaped connecting cylinder is provided at the end of the snorkel main body. It is possible to absorb even a slight change applied in the perpendicular direction. However, due to the expansion and contraction of eaves gutters,
When bending or flattening occurs, the shape of the bellows (mountains and valleys) may be crushed, and at that time, the effect of the bellows does not appear. Therefore, this bellows system cannot cope with expansion and contraction of the eaves gutter when twisting, bending, flatness, etc. occur, and thus there is a problem that the gutter joint, elbow, eaves gutter, etc. are damaged.

Therefore, an object of the present invention is to provide an elbow even if expansion and contraction of the eaves gutter is repeatedly applied in a direction perpendicular to the eaves gutter axis.
The present invention provides a gutter joint in which gutter joints, eaves gutters, etc. are not damaged.

[0010]

The present invention has been made to achieve the above object, and the gutter joint of the present invention according to claim 1 is provided on the outer periphery of the upper end portion and on the bottom portion of the eaves gutter. An upper cylinder body having a flange portion fixed to the peripheral edge of the hole, and a water side connection portion externally inserted to the upper cylinder body at the water upper side end, and an elbow or a spout at the water side end portion.

Embodiments of the present invention will be described in detail below with reference to the drawings. 1 and 2 show an embodiment of the gutter joint of the present invention. FIG. 1 is a perspective view showing the gutter joint, and FIG. 2 is an exploded explanatory view showing a usage state of the gutter joint of FIG.

In FIG. 1, A is a gutter joint, and this gutter joint A is made of synthetic resin (for example, hard vinyl chloride resin) and is composed of a lower cylinder 1 and an upper cylinder 2. As shown in FIG. 2, the lower tubular body 1 is a tubular body 12 having a circular cross section and a circular collar portion 11 formed on the outside of the upper end,
A receiving port 15 is formed at the lower end. An elastic cylindrical body 13 having a circular cross section is inserted and fixed in the lower cylindrical body 1.
A through hole 14 having an elliptical cross section is provided substantially at the center of the hole 3. Small through holes 16 are provided on both sides of the elliptical through hole 14 in the minor axis direction with the through hole 14 interposed therebetween. The outer diameter of the elastic tubular body 13 is almost the same as the inner diameter of the tubular body 12, and the thickness is from the length of the tubular body 12 to the receiving port 1 provided at the lower end portion.
The length is almost the same as the length excluding the length of 5.

As shown in FIG. 2, the upper cylindrical body 2 is a cylindrical body having an elliptical cross section and a circular flange 21 formed on the outer side of the upper end thereof. As for the size, an elastic cylindrical body 13 having a circular cross section which is inserted and fixed inside the lower cylindrical body 1 is used.
The size of the through hole 14 having an elliptical cross section is approximately the same as the size of the through hole 14 at approximately the center. The lower portion 22 of the upper tubular body 2 is inserted into the through hole 14 of the elastic tubular body 13 having an elliptical cross section.

Next, a method of using the gutter joint A will be described. First, the upper tubular body 2 is pulled out from the through hole 14 having an elliptical cross section in the elastic tubular body 13 inside the lower tubular body 1, and the two are separated. Next, the mounting position and direction are determined so that the longitudinal direction of the through hole 14 having the elliptical cross section of the elastic tubular body 13 inside the lower tubular body 1 is perpendicular to the eaves gutter direction. next,
The upper surface of the collar 11 of the lower tubular body 1 is brought into contact with the peripheral edge of the drainage port of the eaves gutter. Next, an adhesive is applied to the lower surface of the collar 21 of the upper cylindrical body 2,
Insert the insertion portion 22 of the upper tubular body 2 into the circular drainage port of the eaves trough and the through hole 14 in which the cross-sectional shape of the overlapped elastic tubular body 13 inside the lower tubular body 1 is elliptical. The eaves trough is sandwiched between 2 and the lower tubular body 1, and the drainage port of the eaves trough and the lower tubular body 1 are connected.

Next, in the receiving port 15 at the lower end of the lower tubular body 1 of the gutter joint A connected to the circular drainage port of the eaves gutter, the indoor end of the elbow is attached to the wall of the building or the like. Insert the outdoor end of the elbow so that it faces the direction. Next, insert a gutter into the indoor end of the elbow, connect the gutter to the gutter, and fix the gutter firmly to the wall of the building with a support.

Then, the gutter joint A, the elbow and the called gutter are L
The eaves gutter that is shaped like a letter and is horizontally attached to the top of the roof and the vertical gutter that is vertically attached to the walls of the building are firmly connected through these gutter joints A and elbows and called gutters. Since the gutter is fixed by the support, the lower tubular body 1 does not come off from the eaves gutter.

An elastic cylindrical body 13 having a circular cross section is inserted and fixed inside the lower cylindrical body 1, and a through hole 14 having an elliptical cross section is provided at substantially the center of the elastic cylindrical body 13. Since the through-hole 14 is attached such that the major axis direction of the through-hole 14 is perpendicular to the eaves gutter direction, when the eaves gutter moves in the axial direction of the eaves gutter due to expansion and contraction due to temperature differences in summer and winter, The upper tubular body 2 fixed to the eaves gutter also acts to move within the through hole 14 of the elastic body 13 having an elliptical cross section, but is absorbed by the elastic tubular body 13, and the elbow, the gutter joint, the eaves gutter, etc. No extra force is applied to the unit and damage can be prevented. Further, even when the eaves gutter is twisted, bent, or flattened due to expansion or contraction, the gutter joint of the present invention can accommodate eaves gutter expansion and contraction, and can prevent damage to the gutter joint, elbow, eaves gutter, etc. . Further, since the small through hole 16 is provided in the short diameter direction of the elliptical through hole 14 so as to sandwich the through hole 14, the elastic effect of the elastic body can be further increased, which is caused by expansion and contraction of the eaves gutter. It can also absorb the force applied in the direction perpendicular to the eaves trough axis.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific structure is not limited to this embodiment, and even if there are design changes and the like within the scope not departing from the gist of the present invention. Included in the present invention. For example, a dust net may be provided at the upper end of the upper tubular body 2. This garbage net catches the dust in the eaves gutter, so that the gutter joint A, the elbow, and the gutter do not contain dust.

Further, in this embodiment, the elastic cylindrical body 13 has an elliptical cross section, and the elastic cylindrical body 13 is provided with the through hole 14 having an elliptical cross section. However, the sectional shape is circular. It may be an elastic cylinder and a through hole. The elliptical cross section can absorb larger expansion and contraction of the eaves gutter than the circular shape. This is because the cross-sectional shape of the elastic tubular body 13 and the through hole 14 is elliptical and the longitudinal direction of the through hole 14 of the elastic tubular body 13 is perpendicular to the eaves gutter direction, so that the inside of the lower tubular body 1 has a cross section. It has a circular shape, and a through hole 14 having an elliptical cross section is provided therein, and since the minor axis direction of the elliptical shape is substantially the same as the elongating and contracting direction of the eaves gutter, the elliptical shape is formed by the elongating and contracting of the eaves gutter. This is because the distance that the upper cylinder 2 moves inside the lower cylinder 1 becomes large.

[0021]

As described above, in the gutter joint of the present invention, since the through hole is provided in the lower tubular body at the substantially central portion of the elastic body, the eaves gutter caused by expansion and contraction of the eaves gutter and the like. The elastic cylinder can absorb the force caused by the twisting, bending, and flattening of the. In addition, as shown in the embodiment, if the elastic cylindrical body and the through hole have an elliptical cross-sectional shape, the inside of the lower cylindrical body has a circular cross section, and the through hole having the elliptical cross section is provided therein. Since the elliptical shape of the minor axis is in the same direction as the eaves-and-groove expansion and contraction direction, the expansion and contraction of the eaves-and-groove increases the distance that the oval-shaped upper cylinder moves inside the lower-gauge, and Can absorb large expansion and contraction. Further, when the elastic cylinder is provided with small through holes on both sides of the elliptical through hole in the minor axis direction with the through hole interposed therebetween, the elastic effect of the elastic cylinder can be further enhanced.
