Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a lower frame of a hinged door made of a composite of a bent stainless steel thin plate and an extruded aluminum alloy material.

(Prior art) (Problem to be solved by the invention) Generally, an extruded aluminum alloy material is often used for the outer frame of a metal sash, but the lower frame is a curved piece of thin stainless steel plate. The material made from this material is hard and does not stain easily, so it is used. However, the material of the conventional stainless steel lower frame is harder than that of aluminum alloy, and when complex shapes are formed using curved objects, problems such as cracks and fissures occur during press forming. There were also limits to accuracy. For this reason, there was a problem in forming the necessary groove for attaching the seal material in the lower frame using only stainless steel material, and as a countermeasure, we created an aluminum alloy profile with a groove for fitting the seal material. In some cases, a thin stainless steel plate was used, but
The work of covering an aluminum alloy profile with a thin stainless steel plate requires time and labor, and ends up being expensive, so we recommend using a lower frame made of a thin stainless steel plate that has excellent airtightness, watertightness, and soundproofing effects. development was desired.

For example, the conventionally known device described in Utility Model Publication No. 54-163036 is a sliding door lower frame made entirely of a single stainless steel plate, and is not a composite material with an extruded material. -The idea described in Publication Utility Model No. 121233 is a composite material idea for the lower frame of the sliding door, but the rail part is made of a stainless steel plate and the rail is fixed to the top surface of the extruded material. This is a modified idea of covering with a so-called hard material, and both of the above two ideas have a simple structure in terms of manufacturing and do not have a structure that deals with airtightness, watertightness, and soundproofing. There is. In addition, Jitsugyo 51-
The idea described in Utility Model Publication No. 13891 is simply to cover the shoelace part of the extruded molded material with stainless steel plate material, which is secured with screws to an anchor separately arranged on the back of the lower frame. Since the shape groove is integrally formed with extruded material as part of the other lower frame part, the stainless steel plate serving as a protective material and the anchor can be placed outside the lower frame with normal functions. It is impossible to avoid high costs due to the addition of material costs, processing costs, and installation costs. The purpose of the present invention is to solve the above-mentioned problems by using a thin stainless steel plate that has excellent airtightness, watertightness, and sound insulation effects, is easy to process in production, is cost-effective, and can be easily positioned accurately during assembly. The purpose of the present invention is to provide a lower frame of a hinged door made of a composite material of a curved material and an extruded aluminum alloy material.

(Means for Solving the Problems) Hereinafter, the configuration of the present invention will be described with reference to embodiments of the present invention shown in the drawings.

(Effects of the Invention) The lower frame of a hinged door made of a composite material of a curved stainless steel thin plate and an extruded material according to the present invention has the above-described structure and function, so that when assembled, the lower frame of the hinged door according to the first invention By bringing the upper edge 34a of the mounting rib 34 of the lower frame main body B and the upper surface 20a of the seal mounting member D into contact with the lower surface of the horizontal web 35a of the parting edge 35, the seal mounting member D can be easily and quickly attached. Positioning at a fixed position is possible, and in the second invention, the above positioning is performed by connecting the long groove 19e on the lower surface of the joining rib 40 of the seal mounting member D to the upper edge 37a of the mounting rib 37 of the lower frame main body B. In addition, since the joining rib 40 is fixed in three layers, the mounting rib 37 and the parting edge 35, the acceptance thickness of the threaded part of the screw is smaller than when screwing into a single thin plate tap. Since the screws are long and act effectively, loosening of the screws due to impact when opening and closing the hinged door 2 can be reduced.

Furthermore, even if the mounting part of the sealing material is formed into a complicated shape, which is the case with the lower frame of metal sashes that rely only on bent thin stainless steel plates, the sealing action can still function perfectly. First, it was not possible to obtain a high degree of airtightness, watertightness, and soundproofing performance due to the limits of processing accuracy of each component part due to the bending work, whereas it was not possible to obtain a high degree of airtightness, watertightness, and soundproofing performance. By disposing the seal mounting member on the lower frame made of a curved thin stainless steel plate, the lower frame of the present invention can be used because it is possible to achieve a sufficiently high sealing effect with respect to the above-mentioned performance. By doing so, the function of the metal sash in air-tight and water-tight hinged doors is further enhanced, and the production cost is considerably reduced compared to conventional products in which the aluminum profile is coated with stainless steel material. It is possible to do so.
