[Detailed description of the device]

[0001]

[Industrial applications]

 The decorative sash according to the present invention is used, for example, to surround the four circumferences of a glass panel forming the outer wall surface of a building and to arrange the appearance of the outer wall surface.

[0002]

[Prior art]

 It is widely practiced to cover the outer wall of a building with a glass panel, but when constructing such an outer wall, the peripheral edge of the glass panel is supported by a window frame. Window frames are generally made of extruded aluminum. A part of the window frame is exposed on a part of the outer wall surface described above. If this exposed part is the extruded material, the appearance of the building will be inorganic. For this reason, conventionally, as described in, for example, Japanese Patent Application Laid-Open No. 3-107043, there is known a decorative sash in which a part of the window frame exposed to the outer wall surface is made of synthetic resin.

This conventionally known decorative sash, as shown in FIG. 5, includes a main frame 1 which is an extruded material of aluminum (including pure aluminum and an aluminum alloy; the same throughout the specification), And an auxiliary frame 2 which is an extruded material of synthetic resin. Three ridges 3 and 4 are formed on the outdoor side surface of the main frame 1, and locking grooves 5 and 5 are formed between adjacent ridges 3 and 4. On the indoor side surface of the auxiliary frame 2, there is formed a locking projection 6 having a shape and size that can be pushed into these locking grooves 5, 5.

On the outer side surface of the locking projection 6 and the inner side surfaces of the locking grooves 5 and 5, there are formed ratchet tooth-shaped corrugated portions which can be engaged with each other. Therefore, the locking projection 6 can be pushed into the locking grooves 5 and 5 while elastically deforming the projections 3 and 4, but after the pushing, the corrugated portions are engaged with each other. The locking projection 6 is prevented from slipping out of the locking grooves 5, 5.

When locking the peripheral edge of the glass panel 7, the end edge of the glass panel 7 is butted against the side surface of the ridge 3 via the spacer 8, and the outer peripheral edge of the glass panel 7 After the packing 9 is sandwiched between and the outer side surface of the main frame 1, the locking projection 6 is pushed into the locking grooves 5, 5. After the pressing is completed, the peripheral edge of the glass panel 7 is sandwiched between the auxiliary frame 2 and the main frame 1.

As described above, the main frame 1 and the auxiliary frame 2 are combined to form a decorative sash, and the main frame 1 made of aluminum is exposed on the outer wall surface of the building while supporting the peripheral edge of the glass panel 7. However, only the auxiliary frame 2 made of synthetic resin is exposed. Therefore, the appearance of the building will not be inorganic.

[0007]

[Problems to be solved by the device]

 However, in the case of the conventional makeup sash configured as described above, there are the following problems to be solved.

Although the glass panel 7 is held down by the auxiliary frame 2 made of synthetic resin, when the holding force by the auxiliary frame 2 is sufficiently secured and the outdoor pressure becomes lower than the indoor pressure, such as when the wind is strong. In order to prevent the glass panel 7 from falling off, the thickness of the auxiliary frame 2 must be appropriately increased. As a result, the amount of protrusion of the auxiliary frame 2 from the outdoor surface of the glass panel 7 becomes large, and the degree of freedom in designing the outer wall surface of the building is limited.

It is difficult to secure the supporting strength of the glass panel 7 by the auxiliary frame 2 made of synthetic resin. In particular, when the auxiliary frame 2 is heated during a fire, the supporting force of the auxiliary frame 2 is lost and the glass panel 7 may fall.

When the window frame is configured by combining the main frame 1 and the auxiliary frame 2, it is difficult to obtain the flatness of the outdoor side surface of the auxiliary frame 2. If the flatness is poor, it is not preferable because the exterior wall surface of the building does not have a high-class appearance.

The makeup sash of the present invention is intended to eliminate any of the above inconveniences.

[0012]

[Means for Solving the Problems]

 The decorative sash of the present invention comprises a main frame which is an extruded aluminum material, a step portion formed on an inner peripheral side portion of an end portion on the outdoor side of the main frame, and the main frame described above in a state of covering the outdoor side of the step portion. Auxiliary frame that is an extruded aluminum material that is fixed to the outdoor side surface of the auxiliary frame and that supports the peripheral edge of the panel between it and the above step, and a non-metallic material that is attached to the outdoor side surface of this auxiliary frame. And the covering material.

The covering member includes a main engaging portion between an engaging groove formed on the outdoor side surface of the auxiliary frame and an engaging portion formed on the inner side surface of the base chamber of the covering member, and the main engaging portion. The auxiliary frame is connected to the auxiliary frame at two points, namely, an auxiliary engaging portion provided on a portion of the cover member closer to the tip in the width direction.

[0014]

[Action]

 When the peripheral edge of the panel is supported by the decorative sash of the present invention configured as described above, the auxiliary frame is attached to the main frame with the peripheral edge of the panel engaged with the stepped portion of the main frame. Combine and fix. Then, by attaching a covering material to the outdoor side surface of the auxiliary frame, the aluminum auxiliary frame is prevented from being exposed to the outdoor side surface.

Since the cover member is connected to the auxiliary frame at two places, that is, the base end portion and the portion near the tip in the width direction, the tip end of the cover member is exposed from the outdoor side surface of the panel even when the wind is strong. I will never leave.
