Description

[Detailed description of the invention] This invention relates to a corner joint for a nose comb.

In open storage sheds and open garages, a nose shield board is attached to the edge of the roof.

This is just to make it look better, but
In some cases, this may also be used as an eave gutter.

The nasal comb plate is composed of a long body with a constant cross section.

In order to attach this to a building, it is necessary to connect it by bending it at a bend in the roof, but in the case of a normal building, the angle of this bend is a right angle.

Therefore, to attach the nose comb plates, it is sufficient to connect the nose comb plates so as to be orthogonal to each other.

Therefore, in this case, in order to neatly finish the connection part of the nose comb plate, it is sufficient to prepare only one type of right-angled corner joint.

However, open storage sheds and open garages are often installed at the corner of the site to match the topography, so the planar shape of the roof is not necessarily a right angled quadrilateral, but may be trapezoidal or trapezoidal. It becomes.

Therefore, when attaching nose comb boards to such a roof, the nose comb boards are not necessarily orthogonal to each other, and need to be connected at various angles depending on the situation.

In such cases, it is not easy to finish the seams of the nasal comb board beautifully.

Therefore, there was a need for a corner joint for a nose comb plate that could be used in a variety of situations.

This idea was born in response to this need.

This invention provides a corner joint for nose combs, in which two small pieces each having a cavity large enough to insert a nose comb plate are connected by a shaft, and the small pieces are rotatable around the shaft. The main point is to be able to freely change the angle of intersection of comrades.

This device consists of two pieces with a cavity large enough to insert a nasal comb plate, and a shaft is attached to the back side at one end of one piece and the other end of the other piece, and the front side is Alligator curved parts are attached, the curved parts are rotatably connected to each other with a common shaft part, and one of the curved parts is placed in the inner side of the other curved part and brought close to each other, and the curved part is inserted into the inner side. A nose comb, in which the outer surface of the part has an arc shape formed by rotating a small piece around the shaft part, and the inner surface of the end of the curved part located on the outside is close to the outer surface. The present invention relates to corner joints for use.

This idea is explained based on the drawings.

FIG. 1 is an exploded perspective view of the joint according to this invention, FIG. 2 is a perspective view showing how the joint according to this invention is used, and FIG. 3 is an exploded perspective view of the joint according to this invention. FIG.

In FIG. 1, 1 and 2 are small pieces constituting the joint.

Small pieces 1 and 2 each have a cavity 11.21 sufficient for inserting a nasal comb plate, and when arranged facing in the same direction,
The front side of each opposite end is provided with a curved part 12.22, and the reverse side is provided with a respective shaft part 13.23.

Pieces 1 and 2 are the cavity 11.21 into which the nasal comb plate is inserted.
The base material portions 10 and 20 provided with the same cross-sectional shape have the same cross-sectional shape.

However, the curved portions 12 and 22 have slightly different structures, and the shaft portions 13 and 23 are slightly different in that they are provided at complementary positions.

The structure of the curved parts 12 and 22 will be explained as follows.

The curved portion 12 of the small piece 1 is sized to be inserted into the curved portion 22 of the small piece 2.

Therefore, in the small piece 1, a crease is formed at the transition from the base portion 10 to the curved portion 12, but no step is formed.

However, in the small piece 2, a stepped portion is formed at the transition from the base material portion 20 to the curved portion 22, and the curved portion 22 protrudes by an amount corresponding to the thickness of the curved portion 22.

Further, the outer surface of the curved portion 12 of the small piece 1, that is, the surface thereof, has an arc shape in which the cross-sectional shape of the base material portion 10 is rotated about the shaft portion 13.

The curved portion 22 of the small piece 2 may be arcuate like the curved portion 12, but this is not necessarily necessary.

The curved portion 22 only needs to have its end 24 shaped closely to the outer surface of the curved portion 12 of the piece 1; If it doesn't stand out, that's enough.

Therefore, the curved portion 22 is made into a prismatic shape to the extent that the appearance is not impaired.

In the small piece 1, an inner wall 15 is attached to a part of the end of the curved portion 12.

The inner wall 15 is provided to support the shaft portion 13 and is connected to the bottom and back side lower piece 16.

Further, in the small piece 2, an inner wall 25 is attached from the stepped portion of the curved portion 22 toward the back side.

The inner wall 25 is provided to support the shaft portion 23 and is connected to the bottom and back side lower piece 26.

The shaft portions 13 and 23 are provided at complementary positions, and both have a shaft hole in the center.

In addition, on the back sides of the small pieces 1 and 2, in addition to the above-mentioned lower pieces 16 and 26, upper pieces 17 and 27 are attached,
These upper and lower pieces surround the nasal comb plate.

As a result, a cavity 11.21 is formed in the enclosed area.

Small piece 1 and small piece 2 are combined as follows.

That is, the curved part 12 of the small piece 1 is inserted into the curved part 22 of the small piece 2, and the shaft part 23 is inserted between the shaft parts 13, and the shaft 3 is fixed by passing through the shaft hole.

Then, the intersection angle between the small piece 1 and the small piece 2 can be freely adjusted with the axis 3 as the center.

The adjustable range is from a position where the inner walls 15 and 25 are in close contact to a position where the end 24 of the curved portion 22 is separated from the end of the curved portion 12.

The assembled state of what is shown in FIG. 1 is shown in FIG.

In FIG. 2, pieces 1 and 2 are connected by a shaft (not shown) so that the angle of intersection can be changed.

Even if the intersection angle between the small pieces 1 and 2 is made acute, the curved portion 12 of the small piece 1 only increases the exposed portion, and no particularly unsightly gap is created.

Conversely, when the intersection angle is obtuse, only the exposed portion of the curved portion 12 is reduced, and no gap is created.

Therefore, by inserting the nose combing plate 4 over the small piece 1 and inserting the nose combing plate 5 over the small piece 2, the intersection angle between the nose combing plates 4 and 5 can be changed freely. It is possible to keep the intersections beautiful.

Note that 18 and 28 are screw insertion holes for fixing the small pieces 1 and 2 to the nose comb plates 4 and 5, respectively;
and 29 are screw insertion holes for fixing the curved parts 12 and 22 to each other.

The joint of this invention is convenient for attaching a nose cover plate to a roof that does not have a right-angled quadrilateral shape.

Specifically, in garages and open storerooms, the roof may not be in the shape of a right rectangle, as already mentioned.

For example, as shown in FIG. 3, a roof frame is made by placing girder members through d and end members e on pillars a.

At this time, the end member e is perpendicular to the girder member, but the girder members A, C, and D are not parallel to each other.

It happens when there is an obstruction at one end and it has to be retracted by a length f.

In this case, both ends of the nose comb plate provided along the companion member d intersect at an acute angle or an obtuse angle.

In such a case, if the joint of this invention is used at both ends of the companion member d and i, the nose comb plate can be connected beautifully.

Therefore, the joint of this invention is useful as a corner joint for nose combs.
