Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a decorative aluminum aluminum material used as a handrail member, a sash member, a fitting member, an exterior / interior member, and the like.
[0002]
[Prior art]
Aluminum shapes are surface-treated by alumite processing.Even if a grained pattern is formed by special alumite processing, the metal feels cold. A decorative aluminum profile is provided. Conventionally, a composite resin sheet or composite resin profile having a two-layer cross section has been used as the resin coating material, and both have been fixed to an aluminum profile and fixed with an adhesive.
[0003]
In the composite resin sheet, a relatively soft resin is used for the lower layer, and a pattern such as wood grain is displayed on the surface of the film as the upper layer by a method such as printing. The composite resin shape is a channel shape that corresponds to the surface and both side surfaces of the aluminum shape, and is formed by extruding the lower layer base material with hard vinyl chloride and the upper layer coating material with soft vinyl chloride. By mixing wood powder or the like in advance into the material of the covering material, a grain pattern is exhibited during extrusion.
[0004]
[Problems to be solved by the invention]
According to the conventional resin decorative aluminum profile as described above, since an adhesive is used to cover the aluminum profile with the resin profile, it is necessary to apply the adhesive over the entire surface, so it takes time and effort, of course. Even if it is replaced to change the pattern due to the decay of the resin, it cannot be easily peeled off, and difficult work such as hulls is forced at that time, and it is easy to recycle after dismantling the handrails etc. It was inconvenient for work to separate. In the case of a resin sheet, it was almost impossible to easily peel it off.
[0005]
In addition, cushioning can be obtained by coating a composite resin sheet or a composite extruded profile, but in the case of a resin decorative aluminum profile having corners on both sides, such as a rectangular support or a plate, the resin member is bonded to the aluminum shape by bonding. Because it is firmly integrated with the material and its hardness is easy to reach the surface, when the head is accidentally hit at the corner, for example, the impact received is strong, so the degree of pain and the degree of danger are reduced. Was not enough.
[0006]
In view of the above-mentioned circumstances, the present invention uses a composite resin material for coating an aluminum material, and is easy to disassemble for coating, remodeling and disposal, and It is an object of the present invention to provide a resin-molded aluminum profile which is safe even when there are corners on both sides, since the cushioning property of the portion is particularly improved.
[0007]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention relates to a method in which an aluminum material extruded into a rectangular hollow body and a hard channel-shaped base material having engaging claws projecting from both ends are integrated with a soft coating material. It is composed of a resin profile that is extruded and formed in a composite form, and by forming a recess in the aluminum profile, an engaging claw is formed at the edge of the aluminum profile to engage with the engaging claw of the resin profile. The nail is formed with a slope with a clearance angle that slopes high from the recess at the part that joins the hook and the hook at the hook, and the resin shape is detachably attached to the aluminum shape without adhesive. Further, in the aluminum profile, a stepped portion as a surface which is lowered by the step is formed up to each corner end near both side corners of the upper surface on which the resin profile is adhered. There is a space between the stepped part of the It was to constitute a resin decorative aluminum profiles.
[0008]
[Operation]
According to the above structure, when assembling the resin decorative aluminum profile, the channel-shaped mouth is pressed onto the aluminum profile, and the resin profile is elastically deformed and fitted. In this case, the engaging claws at both ends are hooked on the engaging portions of the recesses of the aluminum profile. However, the engaging claws are integral with the hard base material, and the coating material prevents the deterioration of the base material. Even if no adhesion is made, a stable adhered state is maintained for a long time. In addition, since the hook of the engaging claw is in contact with the hook at the slope of the clearance angle, in addition to the situation where the adhesion becomes an obstacle when peeling the resin profile for pattern change, etc., Since the engaging claws come off easily, the resin profile can be easily removed. Further, when the resin member is applied, the resin member acts on the slope by elastic force, so that a pulling action occurs and the resin member easily adheres to the aluminum member.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, the cross-sectional shape of the aluminum profile 5 as the main body is not limited to a rectangle (FIGS. 1 and 3) or an ellipse (FIG. 4), but may be other polygons or circles. . In any case, since the base material 29 is hard and the covering material 31 prevents the deterioration thereof, the engaging claws 25, 25 formed of an integral material with the base material 29 stably maintain the joined state to the aluminum profile 5. I do.
[0010]
With respect to the hard resin of the base material 29, an ABS resin having better impact resistance than conventionally used hard vinyl chloride is preferable from the viewpoint of stable coupling of the engaging claws 25 in particular. However, since the ABS resin is inferior in weather resistance, if the coating material 31 is made of an AAS resin having good weather resistance (an acrylic rubber obtained by graft-polymerizing acrylonitrile and styrene), the adhesion strength of the composite resin shape 7 is reduced. It is kept more stable over time.
[0011]
Further, in the present invention, since the steps 19, 19 are provided at both side corners of the upper surface of the aluminum profile 5, the fitting of the resin profile 7 becomes somewhat easier, and the space 27 provides good cushioning. It becomes. Further, even if the resin profile 7 is tightly bonded to the aluminum profile 5 due to the change of the material over time, the resin profile 7 is separated in two steps at the boundary of the space 27. No hindrance occurs, which makes it easier to remove.
[0012]
【The invention's effect】
As described above, according to the resin decorative aluminum profile of the present invention, the composite resin profile is used for coating the aluminum profile. The engaging claw of the material is formed with a slope with a clearance angle that hits the hook of the aluminum shape, so it is easy to combine for covering, reassemble, and disassemble for disposal. Can be tightly bonded to the resin profile. In addition, the step surface of the step facilitates the operation of attaching the resin profile, and furthermore, the space has a particularly good buffering property, so that it is safe and the resin profile can be easily removed. There is.
[0013]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings.
[0014]
FIG. 1 shows an example in which the present invention is embodied as a pillar member 1 of a handrail such as a veranda (see FIG. 4). The pillar member 1 is formed of resin profiles 7 on both left and right sides of an aluminum profile 5 as a pillar body. And the entire surface except for the center of the width of the front and rear surfaces is covered with the resin profiles 7.
[0015]
The aluminum profile 5 is hollow with a substantially rectangular cross section on both sides, and exposed portions 9, 9 which are not covered with the resin profiles 7, 7 and are flush with the resin profiles 7, 7 protrude from the center of the width of the front and rear surfaces. The recesses 11, 11 are formed on both sides thereof, and the slanted hooks 15, 15 are formed at the outer opening edges of the recesses 11, 11, respectively. A pair of screw pockets 17, 17 are formed on the both side walls so as to open outward, and the outer surface is lower than the central portion from the opening to the corner and is slightly recessed, and the step bottom surfaces 19, 19 are formed. Is formed as A slope 20 is formed at the end of the step bottom surface 19 at the corner.
[0016]
The resin profiles 7, 7 are extruded as U-shaped channel members having side walls formed at right angles to both ends of the width-side wall, and the recesses 11, 11 of the aluminum profile 5 are formed at the ends of the side walls. The engaging claws 25, 25 that fall into the hook portions 15 and protrude from the hook portions 15, and a portion that comes into contact with the hook portions 15 is formed on a slope 26 having a clearance angle. Therefore, when fitted to the aluminum profile 5, the slope 20 serves as a guide for the engagement claws 25, and then the slope 26 at the clearance angle serves as a guide, so that the resin profile 7 comes into close contact with the aluminum profile 5. In addition, it serves as a guide when the slope 26 at the clearance angle is removed. A space 27 is formed between the aluminum profile 5 and the resin profile 7 due to the fitting, due to the step bottom surface 19, the slope 20, and the opening of the screw pocket 17.
[0017]
Since there is such a space 27 in the combined state, the corner portion has a good cushioning property against an impact from above the resin profile 7. When the resin profile 7 is replaced for changing the pattern, an appliance is inserted into the space 27 from the end (arrow Pa), the space between the aluminum profile 5 and the resin profile 7 is expanded, and the other appliance is used. It can be removed by applying the expansion in the other end direction (Pb). When performing such an operation, it is necessary to once dismantle the handrail. Regarding the material of the resin profile 7 as a composite profile, the inner base material 29 is made of ABS resin, the outer coating material 31 is made of AAS resin, and the coating material 31 is mixed with wood powder in advance and extruded. A wood grain pattern is exposed on the surface by molding (FIG. 2).
[0018]

The resin decorative aluminum profile is a pair of left and right hollow bodies 33, each having an aluminum profile 5 formed in a hollow rectangular cross section. 33 are connected by a bottom plate 35, and a concave groove 37 is provided therebetween. It should be noted that the groove 37 is screwed to a joist or the like. In addition, step bottom surfaces 19, 19 are provided at the left and right corners of the upper surface, so that spaces 27, 27 are formed between the upper surface and the resin material 7. Further, on both left and right ends of the lower surface, there are formed stepped recesses 11, 11 on which the engaging claws 25, 25 of the resin profile 7 are hooked, and the outer corners thereof are cut off to form the hooking portions 15 on the slopes. .
[0019]
In the case of this embodiment, since the width is large and the width is easy to bend, the resin shape member 7 can be easily removed as compared with the case of the above embodiment. Therefore, it is not always necessary to insert the device into the space 27 like a wedge, and the device can be easily removed by lifting both side ends (Pd) while strongly pressing the location of the concave groove 37 (Pc). In the state where the floor is stretched, the space is provided between the adjacent treads, so that the hook can be lifted by hanging the hooking device on the engaging claw 25 in the same state. do not do.
