Description

[Detailed Description of the Invention] Since the rafters in Japanese-style architecture are visible at the eaves, it has recently been proposed to protect the tips of the rafters and enhance the decorative effect of the building by fitting decorative metal fittings to the tips of the rafters. It has become popular in residential buildings as well. Although the diameter of the rafters is supposed to be the same, there are differences in dimensions due to the steps of sawing and planing, so in order to make the decorative end fittings closely fit the outer shape of the rafters, each piece must be measured and handmade. This requires a lot of effort and costs a lot of money.

In view of this point, the present invention focuses on making the diameter of the decorative fitting at the end of the rafter adjustable, and holds a plurality of corner pieces as a cylinder forming a polygon so that it can be enlarged and contracted. By making the diameter of the decorative metal fittings adjustable in the side length of the polygon in accordance with the outer shape of the polygon, it is possible to accommodate differences in the dimensions of the rafters and to strengthen the front edge.

The invention will be explained with reference to the figures. 1 and 1' are side plates made of copper plates, colored metal plates, synthetic resin plates, etc.
On the front side 2, 2', the front edge portions 3, 3' have a protruding length l,
It is formed into a protruding bent shape with l'.

The two side plates 1 and 1' are arranged in parallel and adjacent to each other, and the front edges 3 and 3' are formed into a bent corner piece a connected to each other with the front edges 3 and 3' inside. In the illustrated embodiment, the side plate 1
In this case, an extension part 4 consisting of the side plate 1 and the front edge part 3 is formed which protrudes beyond the protrusion length l' of the adjacent front edge part 3'. It is shown that an extension 4' consisting of a side plate 1' and a front edge 3' projecting beyond the length l is formed at each end.

A cylindrical body b is formed in which the corner pieces a, a, . In order to hold the cylindrical body b so that it can be expanded and contracted, as shown in the figure, the adjacent corner pieces a and a are slidably superimposed on each other including the extension parts 4 and 4', so that the cylindrical body b can be expanded and contracted. It is shown that.

In the present invention, in the cylinder b, the end edges 6, 6' of the front edges 3, 3' are bent rearward to form a U-shaped cross section together with the side plates l, l'. , the front edge portions 3, 3' are protruded forward to form a convex front edge portion 3.
a, 3'a.

In the illustration, the front edges 3a and 3'a of the protrusions are bent into a U-shape, and the front edge 3a, which has a small diameter, is fitted into the front edge 3'a, which has a large diameter, to form a cylinder b. Indicates that the image is held so that it can be expanded or reduced.

Note that if the extensions 4, 4' are formed, the extensions and retreats of the extensions 4, 4' will not be subject to any other restrictions, and the range of expansion and contraction of the cylinder b will be large, and the difference in the outer dimensions of the rafters will be reduced. The indications for this are wide-ranging.

In the illustration, since the locking piece 8 is bent at the rear side 7' of the side plate 1' and engaged with the adjacent side plate 1, sliding between the two is smooth, and the front edge 3' Since the locking piece 8'' is bent at the tip of the portion 6' and engages with the adjacent front edge 3, the sliding movement between the two is smooth and the shape of the cylinder b is more reliably maintained during expansion and contraction. It is.

To attach the decorative tip fitting of the present invention to the tip of a rafter, enlarge the diameter of the cylindrical body b assembled as described above and fit it into the tip of the rafter.
a, 3'a to the top surface of the rafter, move the corner piece a in the direction of reducing the diameter of the cylinder b, and attach each side plate 1, 1' to each of the rafters c as shown in Figure 2. Can be mounted close to the side.

In this way, the tip decorative metal fitting has a convex front edge 3a,
3'a is engaged with the tip surface of the rafter, and the convex front edges 3a, 3'a protrude and cover the front end surface of the rafter, but there is also a relationship in which the diameter of the cylindrical body b expands and contracts. It is difficult to cover the entire tip surface. In the present invention, we also considered the supplementary use of a front plate to help cover the top surface of the rafter.

The front plate 9 is made of the same material as the side plates 1 and 1', and is formed into a polygonal shape corresponding to the shape of the cylinder b, so that it comes into contact with the front surface of the rafter and is restrained by the convex front edges 3a and 3'a. Bye. In the present invention, the leading edge portions 3, 3'
Correspondingly, each edge 9a, 9b of the front plate 9 is bent toward the front side to form locking edges 10a, 1.
0b...... was installed protrudingly.

In addition, like the front plate 9, a support plate 11 made of a copper plate, a colored metal plate, a synthetic resin plate, etc. is attached to one end of the support plate 11.
Adhesion such as soldering, welding, etc. 13 to the inner surface 12 of the side plate 1 by using the attachment piece 11b bent at a.
The locking edge 1 of the front plate 9 is provided behind the front plate 9.
0a, 10b...... are fitted into the front edge 3,
If it is placed in a manner that prevents it from coming off backward from 3', it will be convenient to handle it as a decorative end fitting.
In FIG. 3, the support plates 11 are provided on both sides of the opposing side plates 1, but only one side plate 11 may be provided.

In the present invention, although the case where the rafters are quadrangular is illustrated, it is also possible to use appropriate polygonal rafters such as triangles and pentagons, with adjacent side plates 1 and 1' of the corner pieces a corresponding to the inner angles thereof. The bending angle can be determined and applied.

In addition, in the embodiment, since the protrusion 7 is formed at the corner of the rear side 7' of the corner piece a, even if the metal fitting is shallow due to the formation of the U-shaped cross section, it can be firmly fitted to the rafter. It will improve your appearance and improve your appearance.

The decorative end fitting for a raft according to the present invention has a front edge protruding from the front side of the side plate in a bent shape, and a corner piece that connects adjacent side plates in a bent shape with the front edge inside. , and the corner pieces are formed into a cylindrical body which is held so as to be expandable and contractable with the inner angles inside, so the corner piece a is selected and used according to the polygon of the rafter, Both side plates 1 of each corner piece a,
1' and the convex front edges 3a and 3'a respectively cover the sides and the front edge of the rafter, and if necessary, the front plate 9 can also be used in combination to cover the entire front edge for protection. , without producing a decorative effect, the cylinder body b can be easily adjusted to match the polygonal external dimensions of the rafter by moving the adjacent corner pieces a back and forth to enlarge and contract the cylinder body b.

The decorative end fitting for the rafter according to the present invention is characterized in that the cylindrical body b
The end edges 6, 6' of the front edges 3, 3' are bent rearward to form a U-shaped cross section together with the side plates 1, 1'. The front edges 3a, 3'a of the ridges are protruded forward to form the front edges 3a, 3'a of the ridges. Not only does it protrude as a part and give a three-dimensional beauty, but it is also structurally solid, and by extension, the structure of the wooden end decorative metal fitting of the present invention can be made solid as a whole. Next, the convex front edge 3a,
The fact that 3'a forms a U-shaped cross section is convenient for holding the cylinder b by connecting the corner pieces a, a, . . . with each other, and the holding is also firm. In addition, a front plate 9 having locking edges 10a, 10b erected on the edges 9a, 9b is used, and the locking edges 10a, 10b are inserted into the U-shaped cross sections of the convex front edges 3a, 3'a, . If the front plate 9 is brought into contact with the end edges 6 and 6',
A drain is formed without any gap being felt between the end edges 6, 6' and the front plate 9, and rainwater can be prevented from entering the top surface of the rafter.

In this way, the present invention provides a solid and beautiful tip that adheres closely to the outer shape of the rafter and has a convex front edge on the front surface by simply preparing a number of corner pieces corresponding to the polygonal corners of the rafter. Since decorative metal fittings can be obtained, the effect of reducing labor and cost is enormous compared to the current situation where each rafter is individually measured and handmade, and mass production becomes possible.
