Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a window rim, particularly a window rim made of an inorganic hardened material.

[Means to solve the problem]

In recent years, sashes made of inorganic hardened materials such as fiber-mixed slag cement-based sashes have been attracting attention from the standpoint of heat insulation and heat resistance. However, in the case of this inorganic hardened sash, since it is a brittle material compared to ordinary metal sashes, it is necessary to devise a shape and an attachment method. In particular, the method of fixing the rim to the window frame is difficult due to limitations caused by the material, such as strength and shape.

The present invention relates to a heat-resistant and practical shape of a rim made of such an inorganic hardened material, including a rim body made of an inorganic hardened material and having a groove with a substantially U-shaped cross section, The U-shaped tip part has a U-shaped cross section so as to fit and be fixed in the U-shaped groove, and the locking step part that engages with the locking part of the locking strip attached to the window frame. A gap is formed between the tip of the U-shaped guide fixed to the rim main body and the rim main body, and This window sill is fixed by pushing the locking step into the locking portion of the locking strip.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a portion where glass is attached to a window frame 2 using a ridge according to the present invention. This rim consists of a combination of a rim main body 1 and a guide tool 3, and the rim main body 1 is reinforced with an inorganic hardened material such as a slag cement extruded material, preferably mixed with glass fiber roving 12, A groove having a substantially U-shaped cross section is formed in the longitudinal direction. This groove is for fitting and assembling the guide tool 3, and can be obtained during extrusion molding of the rim main body. Note that the window frame 2 is also made of substantially the same material as the rim main body 1.

The guide tool 3 is a long member made of aluminum or the like and has a U-shaped cross section, and the inside of the U-shaped tip has a locking strip 4 attached to the window frame 2 with screws 7, for example. Stop portions are provided facing each other. That is, as shown in FIG. 2, on the inside of the U-shaped tip of the guide tool 3, a locking step 9 for engaging with the locking portion 10 of the locking strip 4 is usually continuous in the longitudinal direction. The locking step portion is provided with a taper 11 so that engagement with the locking strip 4 can be easily achieved by pushing.

The guide tool 3 fits into the U-shaped groove of the rim main body 1 and is fixed to the rim main body 1 with adhesive or screws (not shown) at the bottom of the U-shape. In this case, a predetermined distance a is provided between the U-shaped tip of the guide 3 and the rim body 1. This gap is formed when the ridge is attached to the locking strip 4 by pushing, the locking stepped portion 9 of the guide tool 3 engages with the locking portion 10 of the locking strip 4, and the U-shaped tip expands outward. It is essential to make this possible. For this purpose,
The width interval a of the gap is selected depending on the degree of protrusion of the locking step 9 of the guide 3 so that the U-shaped tip of the guide 3 can be freely expanded.

Further, a step is provided between the inner lower end 8 of the rim main body 1 and the window frame 2 with respect to the outer lower end so as to provide a gap of width b as required. This step improves work efficiency when attaching the glass 5 to the window frame 2 using the rim, and is convenient when the rim is released from the locking strip 4 by utilizing the elasticity of the gasket 6.

In addition, in the drawing, the shape of the locking step 9 of the locking tool 3 of the guide tool 3 and the locking portion 10 of the locking strip 4 are shown to be the same both indoors and outdoors, but the shape of the locking step 9 is particularly different. In order to prevent the pressed edge from falling off due to negative pressure, the indoor side may be made into a corner shape so that it cannot be unlatched from the locking part. Furthermore, the outer surface of the rim main body 1 may be covered with another member.

"Effects of the invention" Since the present invention is constructed as explained above, it is possible to securely and easily attach the rim made of an inorganic hardened material, and it also has excellent strength and is extremely practical. It is.

[Brief explanation of the drawing]

Claims (1)

[Claims for Utility Model Registration] 1. A rim main body made of an inorganic hardened material and having a groove with a substantially U-shaped cross section; has a shaped cross section,
It consists of a guide tool which has a locking step portion facing each other on the inside of the U-shaped tip that engages with the locking portion of the locking strip attached to the window frame, and is fixed to the rim body. A gap is formed between the tip of the U-shaped guide and the rim main body, and the guide is fixed by pushing the locking stepped portion of the guide into the locking portion of the locking strip. Window rim. 2. The window rim according to claim 1, which is a utility model in which reinforcing fibers are mixed into the inorganic cured material. 3. The window rim according to claim 1 of the registered utility model claim, which is provided with a step so as to provide a gap between the inner lower end of the rim main body and the window frame.
