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.

This is the point of this invention! (In view of this, in order to be able to expand and reduce the diameter of the decorative fitting at the end of the rafter, it is formed from a plurality of corner pieces forming a polygon, and the diameter of the decorative fitting is adjusted to match the outer shape of the polygon of each rafter. By making the side lengths of the polygons adjustable, it is possible to accommodate differences in the dimensions of the Daruki.

The invention will be explained with reference to the figures. 1 and 1' are copper plates! A side plate made of a colored metal plate 9 containing a resin plate, etc., and its front side 2.
The front edges 3 and 3' are formed in a protruding bent shape with a protruding length l, /;'. Since the front edges 3 and 3' are bent into a U-shape in the illustration, the protrusion lengths l and e' are large enough, but if desired, the protrusion lengths 7 and >>' can be made relatively large. Alternatively, the front edge 313' can be formed in a folded shape to be as small as possible. The front edge portions 3 and 3' may have any suitable structure, such as simply being formed to protrude in an L-shape.

The two side plates I11' are attached to the protruding front edge 313.
' are arranged in parallel and adjacent to each other, and connected in a bent manner with the front edge portions 3.3' inside. The side plate 1 is provided with a covering portion 4 consisting of the side plate 1 and the front edge 3 that protrudes beyond the protrusion length l' of the adjacent front edge 3', Side plate 1' that protrudes beyond the protrusion length l of portion 3
and a covering portion 4' consisting of a front edge portion 3' to form a corner piece a.

The corner pieces a, a, . The decorative metal fittings for the wooden ends of the present invention are obtained by polymerization.

In the illustration, the leading edge parts 3 and 3' are bent into a U-shape, and the leading edge part 3 with a smaller diameter fits into the leading edge part 3' with a larger diameter, so that the covering parts 4 and 4' overlap. Since the locking pieces 6, 6' are bent and formed on the rear side 5' and the front edge 3' of the side plate 1' to hold the side plate 1 and the front edge 3, the covering parts 4, 4' cannot be slid. Don't be fooled when moving.

To attach the decorative tip fitting of the present invention to the tip of a rafter, enlarge the diameter of the cylindrical body assembled as described above, fit it into the tip of the rafter, and attach the front edge 3 to the tip of the rafter. The corner piece a is moved in the direction of reducing the diameter of the cylindrical body 7, and each of the side plates 1 and 1' is attached to each side of the rafter C in close contact with each other as shown in FIG.

In this way, the front end decorative metal fittings engage and cover the tip surface of the rafter with the front edges 3 and 3', but due to the expansion and contraction of the diameter of the cylindrical body, the tip surface is completely covered. It is difficult to do so. In the present invention, we also considered the supplementary use of a front plate to help cover the tip of the Daru tree.

The front plate 7 is made of the same material as the side plates 1 and 1', is formed into a polygonal shape corresponding to the shape of the cylindrical body, and is brought into contact with the front surface of the rafter to prevent it from sliding against the front edge 313'. In the illustration, since the front edge portion 3I3' is bent into a U-shape, the edges 7a + 7b + . Edge 8a+8b+
...... was established.

Also, like the front plate 7, it is a copper plate! A colored metal plate 1 is attached to the inner surface 11 of the side plate 1 by soldering or welding 12 by using a mounting piece 10a formed by bending one edge of the support plate 9 made of a metal resin plate or the like. Front plate 7 installed at the back
The front part 3, into which the locking edge 8aν8b+curve...
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 9 are provided on both sides of the opposing side plates 1, but only one side plate 9 may be provided.

In the present invention, although the case where the rafters are quadrilateral is illustrated, it is also possible to fold the adjacent side plates 111' of the corner pieces a corresponding to the internal angles of the rafters in an appropriate polygonal shape such as a triangle or a pentagon. It can be applied by determining the bending angle.

The decorative metal fitting for the end of a raft according to the present invention has a front edge protruding from the front side of the side plate in a bent shape. A corner piece is formed by connecting the corner pieces in a bent manner with the two sides facing each other inwardly, and having a side plate projecting beyond the protruding length of the adjacent front edge part and a covering part consisting of the front edge part. are arranged in an encircling manner to form a cylindrical body, and the covering portions between adjacent corner pieces are slidably overlapped, so that the corner pieces a are arranged in an encircling manner to form a cylindrical body. The side plates I11' and the front edge 3.3' of each corner piece a cover the sides and front edge of the rafter, respectively, and if necessary, the front plate 7 can be used in combination. Protective by covering the entire front end surface! Not only does it have a decorative effect, but the overlap of the covering parts 4, 4' between adjacent corner pieces a can be easily adjusted and matched to the polygonal external dimensions of the rafter by sliding displacement, Moreover, the covering part 4
・Since 4' consists of the side plates l, 1' and the front edge 3T3' that protrude beyond the protruding length l and l' of the adjacent front edge 3.3', the sliding displacement between the covering parts 414' There is a wide range of adaptation to differences in the external dimensions of the rafters, without any other constraints.

In this way, according to the present invention, a decorative end fitting that closely fits the outer shape of the rafter can be obtained by simply preparing a number of corner pieces corresponding to the polygonal corners of the rafter. On the other hand, the effect of reducing labor and cost is enormous and enables mass production.

A decorative fitting for the tip of a rafter, characterized in that it has both a side plate projecting beyond the long side and an extension part consisting of a front edge. ∆Detailed description of the invention It has become popular in modern homes to fit decorative metal fittings to the ends of the rafters to protect them and enhance the decorative effect of buildings.The diameters of the rafters are supposed to be the same size. However, because there are dimensional differences due to the sawing and planing stages, each piece must be handmade using a measuring tool in order to make it closely fit the outer shape of the wood, which requires a lot of labor. In view of this point, the present invention focuses on making the diameter of the decorative metal fitting at the end of the raft adjustable in accordance with the polygonal outer shape of the tree and the side length of the polygon. The present invention will be explained with reference to the drawings. 1.1' is a copper plate. Colored metal plate 9 A side plate made of a synthetic resin plate, etc., with an old plate on the front side 2.2'. The edge portion 3.3' is formed into a protruding bent shape with protrusion lengths t and l.The two side plates 1.1' are arranged adjacent to each other in parallel, and the front edge lR3
, 3' are on the inside and connected in a bent manner. And side plate 1
An extension part 4 consisting of the side plate 1 and the front edge part 3 is provided, which projects beyond the protrusion length 1 of the front edge part 3' adjacent to G.
In the side plate 1', an extension part 4' consisting of a side plate l' and a front saddle part 3' that protrudes beyond the protruding length t of the edge 3 at both ends thereof is provided to form a corner piece a. The corner pieces a, a, . . . are arranged in a surrounding manner with their inner corners 5 inside to form a cylindrical body which is held so as to be expandable and contractable. In order to hold and lower the cylindrical body so that it can be expanded and contracted, an appropriate holding structure is employed, such as by slidingly overlapping the extensions 494' between adjacent corner pieces a and a. In the present invention, in the cylindrical body, the front edge portion 3.3'
The end edges 6, 6' of 1 are bent rearward, and together with the side plates f, /,' are formed into a U-shaped cross section, and the front edges 3, 3' protrude forward. Convex front edge 3a, 3
It is formed by forming an L. In the illustration, the front edges 3a and 3'a of the convex portions are bent into a U-shape 59! , The cylindrical body is held so as to be able to be expanded and contracted by inserting the convex front edge 3a1' with a small diameter into the front edge 1% 3'cL of the convex ridge with a large diameter, but the corner piece a* al・・・
It goes without saying that G's and other appropriate structures are employed to hold the cylindrical body arranged in an encircling manner so that it can be enlarged and contracted.
E172. As shown in (2), since the locking piece 82 is bent at the rear side 7' of the side plate 1' and engages 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 edge B 6' and engages with the adjacent front edge 3, the sliding movement between the two is smooth, and the shape is maintained when the cylindrical body is expanded or contracted. is also more certain. To attach the decorative tip fitting of the present invention to the tip of a rafter, enlarge the caliber of the cylindrical body assembled as described above, fit it into the tip of the rafter, and attach the convex front edge 3a. 3'a to the top surface of the rafter, move the corner piece a in the direction of reducing the diameter of the cylindrical body, and attach each side plate 1, 1' to each side of the rafter C as shown in Figure 2. Can be installed in close contact. In this way, the tip decorative metal fitting has a convex front edge g 31L I 3

fS 3a and 3'a protrude from the front end surface of the rafter and cover it, but it is difficult to completely cover the front end surface due to the expansion/contraction T of the diameter of the cylindrical body. In the present invention, we also considered using the front plate as an auxiliary aid for the Wffi of the tip of the firefly tree. The front plate 9 is made of the same material as the side plates 1.1', is formed into a polygonal shape corresponding to the form of the cylindrical body, and comes into contact with the front surface of the rafter and is restrained by a convex front edge 1% 31L t 3'a. do it. In the present invention, since the trI edge a3.3' is formed into a U-shaped cross section and raised, each edge 9a of the front plate 9 is
, 9b, . . ., the locking edges 10a, mob, . Further, similarly to the front plate 9, a support plate 11 made of a copper plate, a sign metal plate 9, a synthetic resin plate, etc. can be soldered to the inner surface 12 of the side plate l by means of a mounting piece 11b formed by bending one end edge 11a of the support plate 11. are attached or welded 13 to the rear of the front plate 9 to prevent the locking edges 1oa, 10b, . . . of the front plate 9 from separating backward from the fitted edges 3, 3' If it is kept as such, it will be convenient to handle it as a decorative end fitting. In the third figure, support plates 11 are placed on both opposing side plates l.
I've made a plan, but just 10,000 is enough. Although the present invention covers the case where the rafters are square, for the rafters having an appropriate polygonal shape such as triangular or pentagonal, the present invention has a decorative metal fitting at the end of the rafter O, and the front edge of the rafter is bent to the previous side of the side plate. The side plate and the old edge are formed in a protruding shape, and the adjacent side plates are read in a bent shape with the front edge hole facing inside, and the side plate and the old edge protrude beyond the protrusion length 2 of the adjacent @ edge. It is formed by forming a corner piece with an extension hole at both ends, and holding the corner pieces 2 with their inner corners inside so that they can be enlarged and contracted, so that the polygon of the rafter is formed. Select and use angle piece a according to
a 3a and 3'a respectively destroy the side surfaces and the front end edge of the rafter, and if necessary, also cover the entire front end surface by using the Ogo front plate 9 for protection. Not only does it have a decorative effect, but it also allows the adjacent corner pieces a to be extended 1ff and 14.4' and moved together to enlarge and reduce the cylindrical body so that it can be easily adjusted to match the polygonal external dimensions of the rafter. In addition, the front edge 3 adjacent to the extension 4.4'i

and convex front edges 3a, 3'a, the movement of the extensions 4, 4' is not subject to any other restrictions, and the corner pieces a, a... can be moved with their inner angles 5 inward. Large in the range of expansion and contraction of the cylinder held, usually at the front edge 3,
The end edge a6+6' of 3' is bent rearward to form a cross section with the side plates 1, 1', and the front edge 3,
3' Protrude forward and convex front edge 3a, 3'a
Since the front edge portions 3a and 3 of the convex ridges are formed and protruded,
'a, i Because it forms a Goko-shaped cross section, it not only protrudes as a front edge and presents a three-dimensional beauty, but also has a solid structure.
As a result, the entire structure of the decorative metal fitting at the end of the wood according to the present invention can be made more solid. Next, the fact that the front edges 83a and 3'a of the protrusions form a U-shaped cross section means that the corner piece a due to the extension 4.4'
. a. It is convenient for holding the cylindrical body by mutual connection, and the holding is also firm. In addition, a front plate 92 with locking edges 10a, lob erected on the edges 9a, 9b is used, and the locking edges loa, zob are shaped like a cross section of the convex front edge portions 3a, 3'a, . If the front plate 9 is inserted into the inner wall and abuts against the end edge 6.6', the end edge 6.6'
A drain is formed without any gap being felt between ' and the front plate 9, and rainwater can be prevented from entering the top surface. As described above, the present invention provides a tip decoration that is robust and aesthetically pleasing, has a convex mIR portion on the front surface, and adheres closely to the outer shape of the rafter by simply preparing a number of declination pieces corresponding to the polygonal corners of the rafter.
