Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an eaves gutter that is attached to the eaves of a house.

(Prior Art) Some eaves gutters are used in combination with an external type gutter hanger, and others are used in combination with an internal type gutter hanger. Exterior hanging eaves gutters have the outer side or bottom side of the ears secured to the gutter hangers, and the gutter hangers are exposed on the surface of the eaves gutter, so the appearance of the eaves gutters in the installed state is not good. On the other hand, with eaves gutters for internal hanging, the inside or top side of the ears are secured to the gutter hanging tool, and the gutter hanging tool is not exposed on the surface of the eaves gutter, so the appearance when installed is good, but in general, In terms of load capacity, it was inferior to eaves gutters for hanging outside.

Therefore, as a conventional eave gutter for internal hanging,
A concrete explanation will be given using an example of an eaves gutter described in Publication No. 7831.

This eaves gutter has a downward-facing piece protruding from the inside surface of the ear.
This downward facing piece can be attached by locking to the upward facing piece of the gutter hanger. Also.

In the gutter hanger described in the above publication, a spring plate is provided on the upper side of the upward-facing piece, so that the eaves gutter has a downward-facing piece inserted between the spring plate and the upward-facing piece. As a result, the upper surface of the ear is pressed down by the spring plate.

(Problems to be Solved by the Invention) However, in such conventional eaves troughs, the load of the eaves troughs is concentrated on the downwardly facing pieces of the ears. Furthermore, if snow or rain accumulates inside the eaves gutter, a large load combined with the snow and rain will concentrate on the downward facing piece, causing damage. Additionally, even if damage does not occur, if snow or rain accumulates inside the eaves gutter, the load will act on the side walls in a direction that opens them outwards, and this force will deform the downward-facing pieces of the ears. There was also a risk that it would become detached from the gutter hanger. As described above, the above-mentioned conventional eaves gutters have a problem in that they are not suitable for use in areas with a lot of snow or rain because the ears do not have sufficient load bearing capacity.

The present invention has focused on the above-mentioned conventional problems, and an object of the present invention is to provide an eaves gutter that has a good appearance when installed and has excellent load resistance.

7 (Means for Solving the Problem) In order to achieve the above object, the eaves gutter of the present invention has a protrusion formed on the inner surface of the ear formed at the upper end of the side wall,
The protrusion is formed in a mushroom shape with recesses on the upper and lower surfaces of the base, and is hollow.

(Function) In the eaves gutter of the present invention, a protrusion is formed on the inner surface of the ear, and recesses are formed on the upper and lower surfaces of the base of the protrusion. It can be attached by locking the upper recess and the lower recess.

Therefore, when a load acts in the vertical direction, the load is received on the bottom of the recess, preventing it from falling off the gutter hanger, and when the load is applied in the front-rear direction, the load is received on the side of the recess. This prevents it from falling off the gutter hanger. In particular, when a load acts in the front-back direction, the load is
Since it is distributed between the side surfaces of the recess on the upper surface of the protrusion and the four side surfaces of the lower surface of the protrusion, it is reliably prevented from falling off from the gutter hanger.

Furthermore, since the protrusion is formed in a hollow shape, its strength is improved and damage and deformation due to loads are prevented.

In addition, since the elasticity is improved, external shocks can be absorbed and deformation recovery force against external forces can be imparted.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Next, the operation of the embodiment will be explained based on FIG.

FIG. 3 is a side view showing the eaves gutter A attached to the internal gutter hanger B.

The gutter hanger B is an integrally molded product made of synthetic resin, and is composed of a fixing part 21 fixed along the fascia plate C, and a support arm part 22 extending forward from the upper end of the fixing part 21. ing. The support arm portion 22 includes a rear horizontal portion 221 extending substantially horizontally from the upper end of the fixing portion 21, and a rear horizontal portion 221 extending from the upper end of the fixing portion 21 in a substantially horizontal direction.
an inclined part 222 extending diagonally downward from the front end of 21;
The front horizontal part 223 extends from the front end of the inclined part 222 in a substantially horizontal direction. A front page support structure for supporting the previous page of the eaves gutter is provided at the front end of the front horizontal part 223, and a rear page support structure for supporting the rear page of the eaves gutter is provided between the inclined part 222 and the fixed part 21. It has a structure.

The previous page support structure includes an upper locking piece 23 and a lower locking piece 24 vertically spaced from the front end of the front horizontal portion 221 at a predetermined interval.
A claw 231 is formed downward at the tip of the upper locking piece 23, and a claw 24 is formed at the tip of the lower locking piece 24.
1 is a structure formed upward. Incidentally, the tip end surface of the upper locking piece 23 and the tip end surface of the lower locking piece 24 are formed into circular arc surfaces.

Further, the rear page support structure has a protrusion 2 on the front surface of the fixing part 21.
5 is provided in a protruding manner, and a spring plate portion 26 is provided in a protruding manner on the rear surface of the inclined portion 222, and the tip of the protrusion 25 and the tip of the spring plate 26 are provided close to each other.

That is, the eaves gutter A of this embodiment has the protruding portion 1 of the previous section 14.
43 is inserted between the upper locking piece 23 and the lower locking piece 24 of the gutter hanger B to lock the four parts 144 on the upper surface to the claws 231 of the upper locking piece 23, and the four parts 145 on the lower surface is locked to the claw 241 of the lower locking piece 24, and then the rear page 15 is inserted between the projection 25 and the spring plate 26, and the lower surface 151 of the rear page 15 is locked to the projection 25. By doing so, it can be attached to the gutter hanger B. In addition, the protrusion part 1 of the previous time 1

Since both tip surfaces are formed into circular arc surfaces, they can be inserted smoothly with little resistance. Furthermore, since the upper end of the protruding portion 143 is formed lower than the upper end of the rising portion 142,
The upper locking piece 23 can be prevented from protruding upward from the rising piece 142, thereby preventing the gutter hanger B from being exposed on the surface of the eaves gutter A at all.

In addition, when the eaves gutter A is attached to the gutter hanging tool B, if a load acts in the vertical direction, the eaves gutter A receives the load on the bottom surface of the recess 144, 145, and the gutter hanger B is removed from the gutter hanging tool B. can be prevented from falling off, and when a load is applied in the front-back direction, falling off from the gutter hanger B can be prevented by receiving the load on the side surfaces of the recesses 144 and 145. In particular, when a load acts in the front-rear direction, the load is applied to the protrusion 143
Side surfaces of the recess 144 on the upper surface and the recess 14 on the lower surface of the protrusion 143
Since it is distributed over the sides of the gutter hanging tool B, it is possible to reliably prevent it from falling off from the gutter hanging tool B.

Further, since the rising portion 142 and the protruding portion 143 of the previous 14 are formed in a hollow shape, the strength is improved and damage and deformation due to load can be prevented. Furthermore, since the elasticity is improved, external shocks can be absorbed and deformation recovery force against external forces is imparted. In particular, since the base of the protrusion 143 is constricted, elastic deformation is rich, and external force can be sufficiently absorbed.
Damage can be prevented.

In this way, the eaves gutter A of this embodiment has an internal hanging type gutter hanging tool B.
By using it in combination, it is possible to improve the appearance in the installed state, and it also has excellent load resistance. Furthermore, due to its excellent load-bearing capacity, it is suitable for use in areas covered by rain or snow.
