Description

[Detailed description of the invention] In this invention, decorative frame members made of aluminum or its alloys are framed at right angles to each other and placed on the inner peripheral side of a frame such as a door frame or window frame made of aluminum or its alloys. This invention relates to a frame such as a door frame with an attached decorative frame.

In framing each decorative frame member attached to the inner peripheral side of a frame body such as a door frame at right angles to each other, each decorative frame member is assembled into a pair of decorative frame members facing each other in a substantially chevron shape with a window glass fitting groove in between. and a connecting wall that integrally connects these decorative frame walls, and has a beveled end so that one end of one of the adjacent decorative frame members is obliquely crossed with respect to the longitudinal direction of the decorative frame member. At the same time, the inner surface of the beveled edge is formed into a sharp slope that can come into surface contact with the outer surface of the decorative frame wall of the other decorative frame member, so that the beveled edge of the one decorative frame member The method of fitting the decorative frame member to the decorative frame wall of the other decorative frame member in a so-called horse riding style is as follows:
This is conventionally known from Japanese Utility Model Application Publication No. 55-80476, and according to this, the end portion of a decorative frame member is, for example,
Even if there is an error in the cutting accuracy when cutting at a 45 degree angle to form a beveled edge, no gap will be created at the joint between the two adjacent decorative frame members.
Since the inner surface of the beveled edge is a sharp slope, no step is formed at the joint, and therefore the appearance can be improved, and the angle of the end of the decorative frame member can be cut relatively roughly. This has the advantage of eliminating the need for dimensional corrections on site and improving work efficiency.

By the way, in the case of the conventional frame with a decorative frame disclosed in the above-mentioned publication, after the decorative frame members are framed at right angles to each other and connected with screws, the outer periphery of the pair of decorative frame walls in which each decorative frame member is placed is The decorative picture frame is attached to the inner periphery of the frame by fitting the side ends into the vertical and horizontal frame members of the frame and connecting the frame members to each other. The frame member is formed into a substantially W-shaped cross section by a pair of decorative frame walls facing each other in a V-shape and a connecting wall that integrally connects the inner circumferential ends of these decorative frame walls. The outer edge of the decorative picture frame wall (the end on the frame attachment side) becomes a so-called free end and is easily deformed, so even when it is attached to the frame, each decorative frame wall may be damaged by wind pressure, etc. acting on the glass. There have been problems in that the frame member has rattled relative to the frame, and in some cases has come off from the frame.

This invention solves the above problems, and for this reason, in this invention, each decorative frame member is
A pair of decorative picture frame walls that face each other in a substantially chevron shape with a window glass fitting groove in between, and a bottom wall that integrally connects the outer peripheral side ends of these decorative picture frame walls and has an engaging convex step on its outer side surface. The end of one decorative frame member of both decorative frame members is formed into a beveled edge so as to be oblique to the longitudinal direction of the decorative frame member, and the inner surface side of the beveled edge is formed as a beveled edge of the other decorative frame member. The frame member is formed with a sharp slope that can come into surface contact with the outer surface of the decorative frame wall, and the engaging convex step portion of the bottom wall of each decorative frame member is engaged with the recessed step portion formed on the inner circumferential surface side of the frame. They are screwed together and the beveled edge of the one decorative frame member is fitted over the decorative frame wall of the other decorative frame member.

An embodiment of this invention will be described below with reference to drawings. FIG. 1 shows the appearance of a door. Decorative frame members 2 and 3 are attached to a frame member 1 constituting the door frame of this door, and a window glass 4 is attached to the frame member 1. The edges are fitted into these frame members 2 and 3. Figure 2 is an enlarged view of part A in Figure 1, showing one frame member 2 attached to the door frame 1.

a, and on the other hand, the end of the other frame member 3 is cut at a right angle for easy cutting to form a right-angled edge 6a.
is formed.

More specifically, as shown in FIG. 3, the decorative frame members 2 and 3 are both made of extruded aluminum with the same cross-sectional shape, and have bottomless holes formed between the L-shaped mounting pieces 7a and 7a facing each other. A window glass fitting groove 8 and a pair of decorative frame walls 9a, 9 facing each other in a substantially chevron shape with the window glass fitting groove 8 in between.
a or 9b, 9b and both decorative picture frame walls 9a, 9a
Alternatively, it consists of a bottom wall 10 that connects the outer peripheral side ends of 9b and 9b. Although the decorative picture frame walls 9a and 9b are shown as arcuate surfaces, they are not limited to this arcuate surface, and may be formed as irregular decorative surfaces as appropriate.

The ends of the pair of decorative frame walls 9a, 9a in one decorative frame member 2 are cut at an angle of 45 degrees to form beveled edges 5a, 5a as described above. Note that the ends of the gasket attachment pieces 7a, 7a are cut at right angles as shown. The ends of the pair of decorative frame walls 9b, 9b in the other decorative frame member 3 are not cut at an angle, but have right-angled edges 6a, 6a.
Form it into Therefore, the former beveled edges 5a, 5

The beveled edges 5a, 5a are fitted over the decorative frame wall 9 to the position indicated by a.
Sharp slopes 11a, 11 that are inclined inwardly by chamfering the inner surfaces of the beveled edges 5a, 5a so as not to make surface contact with b, 9b and create a step between the two.
a (see Figure 5). Furthermore, an engagement convex step 10a having a substantially U-shaped cross section is formed on the outer surface of each bottom wall 10 of the decorative frame members 2 and 3 over the entire length of the decorative frame member, while on the inner circumferential surface of the frame member 1. , forming an engaging concave step portion 1a that can be engaged with the engaging convex step portion 10a.

In order to frame each decorative picture frame member 2, 3, first, as shown in FIG. Engage with the recessed step 1a for positioning, and screw the screw 1.
2, and then, while fitting the window glass 4 and the gasket 13 into the window glass fitting groove 8, each decorative frame member 2, 3 is fixed, and each edge of the decorative frame member 2, 3 is tightened as explained in FIG. At this time, various combinations can be considered to form the edges of the frame members 2 and 3 into beveled edges 5a or right-angled edges 6a, such as the one shown in FIG. 6a. One side edge of each frame member 2, 3 is formed as a beveled edge 5a, the other side edge is formed as a right-angled edge 6a, and the beveled edge 5a of the adjacent frame members 2, 3 is formed. Even if the 6th frame wall 9b is successively fitted and joined to the decorative picture frame wall 9b,
As shown in FIG.
5a, both edges of the other frame members 3, 3 are formed into right-angled edges 6a, 6a, and the beveled edges 5a of the adjacent frame members 2, 3 are fitted and joined to the decorative frame wall 9b. You may also do so.

As explained above, according to this invention, each decorative frame member is integrated with a pair of decorative frame walls that face each other in a substantially chevron shape with a window glass fitting groove in between, and the outer peripheral side ends of these decorative frame walls. and a bottom wall that is connected to each other and has an engaging step on the outer surface thereof, and the engaging step on the bottom wall of each decorative picture frame member is engaged with the recessed step formed on the inner peripheral surface of the frame. They are screwed together, and the beveled edge formed at the end of one of the adjacent decorative frame members is fitted over the decorative frame wall of the other decorative frame member. , each decorative frame member is securely and firmly fixed to a predetermined position of the frame body, and therefore, when this frame body with a decorative frame is used as a door frame or window frame, the decorative frame members are prevented from wobbling due to wind pressure, etc. This will not occur, and there is no risk of it coming off the frame.

In addition, as mentioned above, since the beveled edge of one frame member is designed to fit over the decorative frame wall of the other frame member in a horse-riding manner, there may be an error in the angle cutting accuracy when forming the beveled edge. Even if there is, there will be a slight gap on the prospective surface (indoor/outdoor direction), but from the prospective surface (front), the above two edges overlap,
The existence of the gap is not exposed in appearance or appearance, and the appearance is not inferior.

Furthermore, according to this invention, since each picture frame member is directly screwed to the frame body through its bottom wall, it is possible to create a decorative picture frame at the same time by simply assembling the frame body to which each picture frame member is screwed. Since the parts are joined to each other, even if there is a slight error in the angle cutting accuracy of the edge of each frame member as mentioned above, it will not cause any problems, so it is possible to accurately cut the angle using the frame as a reference. Just be careful about how you frame it,
The framework work is that much easier.
