Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to, for example, a window frame provided with a reinforcing member.

[Prior Art] FIG. 3 is a cross-sectional view of a rail portion of a conventional aluminum alloy window frame. In the figure, a frame 2 made of an aluminum alloy has wood screws 3, 3 attached to a frame 1 via an L metal fitting 21 made of a steel plate.
It is fixed by a.

The frame 2 is provided with cavities 5 and 6 for lightening the material, and rails 4 and 4a provided on a glass shoji (not shown) for rolling wheels are provided above the cavities.

In the aluminum alloy window frame configured as described above, the strength is sufficient, but the thermal conductivity is large.

[Problems to be Solved by the Invention] In the conventional aluminum alloy window frame as described above, there is a problem that the heat insulating effect is small because the thermal conductivity is large.

Especially in the winter, the heat generated by heating the room leaked out through the brush (window frame) made of aluminum alloy. As a countermeasure, when the window frame was made of plastic with good heat insulation, the heat retention was good, but there was a problem in terms of strength.

For example, when a heavy load is applied to the upper portion of the rail, the entire deflection occurs.

This invention intends to solve the above problems by using a reinforcing member.

[Means for Solving Problems] In a window frame according to the present invention, a frame tree to which the window frame is attached
An L metal fitting (121) that abuts along the upper edge of (101),
A hollow plastic frame (102) provided so as to cover the metal fittings (121) and provided with one or a plurality of rails protruding, and a metal provided in the hollow of the plastic frame (102). A reinforcing frame (102) and a metal frame (110) which is provided in close contact with the lower side of the plastic frame (102) and which is carried from the lower side of the plastic frame (102) are provided. In a window frame in which the frame is formed integrally with the L metal fitting (121), the metal frame has a surface along the frame (101), a surface along the bottom surface of the plastic frame (102), and a plastic frame.
(102) A surface that supports the frame tree (101) below the bottom surface obliquely upward toward the edge, and has a substantially triangular cross-section in the direction perpendicular to the frame tree (101).

[Operation] In this invention, the metal frame includes a surface along the frame, a surface along the bottom surface of the plastic frame, and a surface obliquely upward from the frame tree below the bottom surface of the plastic frame toward the edge. In addition, since the cross-sectional shape in the direction perpendicular to the frame is substantially triangular,
The load acting on the rail is transmitted to another frame made of aluminum alloy through the frame made of plastic and further supported by the frame.

Therefore, not only the appearance is good, but also the load on the plastic frame is reduced.

Further, in the present invention, since the packing is modified between the plastic frame and the metal frame, rainwater is prevented from entering the inside of the member and dew condensation.

[Embodiment] FIG. 1 is a sectional view of an embodiment of the present invention.

In the figure, 101, 102, 103, 103a, 104, 104a, 105, 1
06 is a portion corresponding to the conventional 1 to 6. Frame 110
Is a wood screw 118 at one end and the frame 102 and the L metal fitting 121.
The other end is fixed to the wood screw 11 via packing 141, 142.
It is fixed to the frame 102 by 6. This frame 110
A flat plate 119 is applied between the head of the wood screw 117 and the head of the wood screw 117 to disperse the stress applied by the wood screw 117. Frame 1
Inside the 02, metal U-shaped metal fittings 120 are provided to support the load applied to the frame 102.
The lower end of is fixed to the frame 101 with wood screws 103.

Next, this function will be described. The frame 102 is made of plastic so as to exhibit a heat insulating action, and the L metal fitting 121 and the U-shaped metal fitting 120 are provided to supplement this strength, but a hollow frame 110 is provided to further supplement the strength and also as a makeup. Of. The top of this frame 110 is packed 14
The 1,142 are installed to prevent rainwater from entering the inside of the member and preventing dew condensation.

The blind lid 115 prevents the wood screw 116 from being exposed. Further, since the frame 110 is a hollow aluminum tube having a narrow tip end and a wide root portion and a curved portion, the frame 110 has a structure that provides sufficient strength and is aesthetically pleasing.

2 (a), (b) and (c) are explanatory views showing modifications of the screw allowances 131, 131a and 131b. In the figure, this screw allowance 131, 131
Both a and 131b are provided vertically inside the frame 110 in a direction perpendicular to the plane of the drawing.

Therefore, even if there is a pitch error in the same direction, it can be fixed.

[Effect of the Invention] As described above, the present invention does not impair the heat retaining effect in the room because the plastic frame and the other frame made of the hollow aluminum alloy are provided below the L metal fittings, and the plastic frame is provided. Has the effect of supplementing the strength of.
