Description

  The present invention relates to a composite material used for gates, gate pillars, fences, chain poles, and the like, and more particularly to a composite material combining a metal material and a decorative member.

Patent Document 1 discloses a fence post in which an aluminum extruded shape member and a wooden cover material are combined. Specifically, a wooden cover material is fitted from the longitudinal direction into the fitting groove portion of the aluminum extruded shape member, and the cover material comes off from the opening portion of the fitting groove portion by an overhanging portion provided at the opening end of the fitting groove portion. It is connected so that it will not come out.
Patent Document 2 discloses a frame material for an aluminum sash window in which an aluminum frame and a wooden end plate are combined. Specifically, the lip portion of the lip groove of the aluminum frame and the long groove of the wooden end plate are fitted together so that the end plate does not come out of the lip groove shape.

Japanese Patent Laid-Open No. 10-159042 Japanese Utility Model Publication No. 58-44772

The conventional fence post described above has a good appearance due to the wooden cover material, but both sides in the width direction of the cover material are covered by the overhanging portion provided at the open end of the fitting groove of the aluminum extruded profile. Since it cannot be seen, the appearance cannot be improved sufficiently.
From this, the aluminum extruded profile and the wooden cover material are connected by fitting the lip portion and the long groove as in the frame material described in Patent Document 2 so that the entire width direction of the cover material can be seen. It is possible.
However, as described in Patent Document 2, in order to fit the lip portion (that is, the rib) of the frame member into the long groove of the end plate without a gap, the thickness of the lip portion and the width of the long groove must be set to predetermined values. In addition, when the thickness is increased or the width is decreased due to a processing error or the like, the fitting may not be possible, and it is difficult to fit the lip portion into the long groove, and the assemblability is deteriorated.
In order to solve this, it is conceivable to make the width of the long groove larger than the thickness of the lip portion. However, if this is done, a gap will be formed between the lip portion and the long groove, and the gap will be visible from the outside. Therefore, the appearance looks bad.

  An object of the present invention is to easily and reliably fit an intermediate rib of a metal material and a long groove of the decorative member in a composite material in which the metal material and the decorative member are combined, and the decorative member comes out of the recessed portion of the metal material. It is to be a composite material that can be connected so that there is no appearance and has a good appearance.

The present invention is a composite material combining a metal material and a decorative member,
The metal material has a concave portion having a bottom portion and a pair of side portions continuously in the longitudinal direction, and the pair of side portions includes a pair of intermediate ribs toward the inside,
A part of the pair of intermediate ribs has a projecting deformed portion toward the bottom of the recessed portion,
The decorative member has a substantially rectangular cross section surrounded by a front surface, a rear surface, and a pair of side surfaces, and has a long groove continuously in the longitudinal direction on the pair of side surfaces, and the width of the long groove is larger than the thickness of the intermediate rib. big,
The rear surface of the decorative member is in contact with the bottom of the concave portion of the metal material, the rear inner surface of the long groove is in contact with the protruding deformed portion, and the front inner surface of the long groove and the intermediate rib are separated from each other, so that the decorative member comes out of the concave portion. So as not to be fitted and connected
The composite material is characterized in that a portion closer to the opening end than the intermediate rib in the pair of side portions opposes the side surface portion of the decorative member and closes the long groove.

  In the present invention, opening end ribs are provided at the opening ends of the pair of side portions, and the end surfaces of the opening end ribs can face the front side of the long grooves on the side surfaces of the decorative member so as to close the long grooves. The pair of open end ribs can close the long groove by facing the front inner surface of the long groove of the decorative member.

According to the present invention, the intermediate rib of the metal material and the long groove of the decorative member are fitted, so that the metal material and the decorative member can be connected so that the decorative member does not come out of the recessed portion. Moreover, since the width of the long groove is larger than the thickness of the intermediate rib, it can be reliably fitted even if there is a processing error, and can be easily fitted.
Moreover, the projecting deformed portion of the intermediate rib is in contact with the rear inner surface of the long groove and the front inner surface of the long groove and the surface facing the bottom of the intermediate rib are separated from each other. It can be firmly fixed without moving in the longitudinal direction.
Since the long groove of the decorative member is closed at a portion closer to the opening end than the intermediate rib in the pair of side portions of the concave portion of the metal material and is not visible from the outside, the appearance is good.

A first embodiment of the present invention will be described.
As shown in FIGS. 1 to 3, a metal material, for example, an aluminum extruded profile 1 is a long material having a recessed portion 2.
The recessed portion 2 has a bottom portion 2a and a pair of side portions 2b. Preferably, the cross section is substantially U-shaped and is continuous in the longitudinal direction. In this embodiment, the bottom 2a is a flat surface, but a rib provided on the flat surface may also be used. The pair of side portions 2b are parallel to each other, but may be oblique (that is, a C shape) so that the opening end side becomes narrow.
A pair of open end ribs 3 and a pair of intermediate ribs 4 are provided integrally with each other on the pair of side portions 2b. The intermediate ribs 4, the bottom portions 2a, and the pair of side portions 2b are close to the bottom portions 2a and form grooves 5.

  For example, the aluminum extruded shape member 1 has a recessed portion 2 formed by a bottom plate 6 and a pair of side plates 7, and an opening end inward piece 8 is provided integrally with each other at the opening ends of the pair of side plates 7. This is the open end rib 3. An intermediate inward piece 9 is integrally provided opposite to an intermediate portion (intermediate portion between the opening end portion and the bottom plate 6) of the pair of side plates 7 to form an intermediate rib 4.

In this embodiment, the aluminum extruded profile 1 includes a pair of main side plates 10 that are integrally continuous with a pair of side plates 7 and a connecting plate 11 that connects the pair of main side plates 10. 11, a pair of main side plates 10 and the bottom plate 6 have a hollow main body 12.
That is, the concave portion 2 described above is formed on one side surface of the main body portion 12.

The decorative member 20 combined with the aluminum extruded profile 1 is a long material having a rectangular cross section having a front surface 20a, a rear surface 20b, and a pair of side surfaces 20c, and a long groove 21 opened in the pair of side surfaces 20c is continuous in the longitudinal direction. Have. The material of the decorative member 20 is preferably a powder-filled composite resin.
The long groove 21 has a substantially rectangular shape with a front inner surface 21a, a rear inner surface 21b, and a side inner surface 21c, and the interval (that is, the width) between the front inner surface 21a and the rear inner surface 21b is the opening end rib 3 and the intermediate rib of the aluminum extruded profile 1. Greater than 4 thickness.

For example, the decorative member 20 includes a front part 22, a rear part 23, and a connecting part 24 that connects the front part 22 and the rear part 23, and the width of the connecting part 24 is smaller than the widths of the front part 22 and the rear part 23. The front portion 22 and the rear portion 23 protrude in the width direction from the connecting portion 24. The long groove 21 that is continuous in the longitudinal direction is formed by the rear surface of the protruding portion of the front portion 22, the front surface of the protruding portion of the rear portion 22, and the side surface of the connecting portion 24 .
The front inner surface 21 a of the long groove 21 is the rear surface of the protruding portion of the front portion 22, the rear inner surface 21 b is the front surface of the protruding portion of the rear portion 22, and the side inner surface 21 c is the side surface of the connecting portion 24.

The decorative member 20 is fitted into the recessed portion 2 of the aluminum extruded profile 1, for example, by sliding and fitting from the longitudinal direction, the rear surface 20b (the rear surface of the rear portion 22) faces the bottom portion 2a of the recessed portion 2, Preferably, the intermediate rib 4 is fitted and connected to the rear inner surface 21b of the long groove 21 so as not to come out of the recessed portion 2 while facing the rear inner surface 21b of the long groove 21 and preferably contacting. That is, there is a rear portion 23 and the groove 5 is fitted.
The opening end rib 3 is in contact with the side surface of the decorative member 20, and the opening end rib 3 closes the long groove 21 so that it cannot be seen from the outside.
In addition, without providing the opening end rib 3, you may make it close | close the long groove 21 by making the opening edge part of a pair of side part 20b oppose to the side part of the decorative member 20, and preferably contact | connect.
In other words, the portion closer to the opening end than the intermediate rib 4 in the pair of side portions 2 b may be opposed to the side surface portion of the decorative member 20.

  Thus, the intermediate rib 4 of the aluminum extruded profile 1 and the long groove 21 (rear inner surface 21b) of the decorative member 20 can be fitted and connected, and the long groove 21 can be connected to the open end rib 3 (on the pair of side surfaces 2b). Since it is blocked by the portion closer to the opening end than the intermediate rib 4 and is not visible from the outside, the appearance is good.

In this embodiment, a part of the intermediate rib 4, for example, a plurality of parts spaced at intervals in the longitudinal direction, is projected and deformed toward the bottom 2 a, so-called caulking.
The protruding deformable portion 4a and the rear inner surface 21b of the long groove 21 are in strong contact with each other so that the aluminum extruded shape member 1 and the decorative member 20 can be firmly fitted and fixed so that they do not rattle or move in the longitudinal direction. It is like that.
The projecting deformed portion 4 a is not visible from the outside due to the opening end rib 3.
Further, the protruding length of the opening end rib 3 is shorter than the protruding length of the intermediate rib 4, and the protruding end surface 3 a of the opening end rib 3 is closer to the front surface 20 a than the long groove 21 in the side surface 20 c of the decorative member 20 (that is, the front portion). 22, the long groove 21 is closed.

When the decorative member 20 is formed by extrusion molding using a powder-filled composite resin, the width of the long groove 21 of the decorative member 20 is large due to restrictions such as the size and shape of the mold to be extruded. For example, the width is 3 to 4 mm.
On the other hand, the thickness of the intermediate rib 4 of the aluminum extruded profile 1 is small. For example, it is about 1 mm.
Since it is like this, it is preferable to carry out as mentioned above.

Next, a second embodiment will be described.
In this embodiment, as shown in FIG. 4, the protruding length of the open end rib 3 of the aluminum extruded profile 1 is lengthened, and the open end rib 3 is opposed to, preferably in contact with, the front inner surface 21a of the long groove 21. The first embodiment is different from the first embodiment in that 21 is made invisible from the outside and the decorative material 20 is solid, and the other configurations are the same.
