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 material of a bent stainless steel plate and an extruded aluminum alloy material.

(Prior Art) (Problems to be Solved by the Invention) Generally, an aluminum alloy extruded material is often used for the outer frame of a metal sash, but the lower frame is made of a bent stainless steel thin plate. The material formed by the method is used because it is hard and does not stain easily. However, the conventional stainless steel lower frame is harder than that of aluminum alloy, and when a complicated shape is formed by bending, problems such as cracks and cracks may occur during press molding. There was a limit in accuracy. Therefore, there is a problem in forming the concave groove for mounting the sealing material required in the lower frame only with the stainless steel material, and as a countermeasure, an aluminum alloy with a concave groove for fitting the sealing material. Although it was possible to use a stainless steel thin plate material as the mold material of the above, the work of coating the stainless steel thin plate on the aluminum alloy mold material requires a lot of trouble and time, and eventually it becomes expensive. However, it has been desired to develop a lower frame made of stainless steel thin plate, which is excellent in airtightness, watertightness, and soundproofing effect.

For example, the conventional invention disclosed in Japanese Utility Model Publication No. 54-163036 discloses a sliding door lower frame made entirely of an integral stainless steel plate, not a composite material with an extruded mold material, but a real one. Although the invention described in Japanese Utility Model Publication No. 51-121233 is a composite material related to the lower frame of the sliding door, the rail part is made of a stainless steel plate and is fastened to the upper surface of the extruded mold material. This is a modification of the so-called hard material coating, and neither of the above two inventions has a simple structure in terms of manufacturing, which does not have a structure for airtightness, watertightness and soundproofing. ing. The device described in Utility Model Publication No. 51-13891 is a device in which the shoe slide of the extruded mold material is simply covered with a stainless steel plate material, so a screw is attached to an anchor separately arranged on the back surface of the lower frame, which is airtight. Since the T-shaped groove for inserting the rubber A is integrally formed by an extruded mold material as a part of the other lower frame part, the stainless plate body and the anchor as a protective material are provided with a normal function. In addition, the material cost, processing cost, and installation cost due to the use outside the lower frame cannot be avoided. The object of the present invention is to solve the problems described above and to have excellent airtightness, watertightness, and sound insulation effects, and at the same time, good workability and cost efficiency in terms of production, and a stainless steel thin plate that can be easily positioned accurately during assembly. It is intended to provide a lower frame of a hinged door made of a composite material of a curved piece and an extruded aluminum alloy material.

With the long groove 19e of the seal attachment member D fitted to the upper edge 37a of the 37, the joining rib 40 was brought into contact with the attachment rib 37, and the parting edge 35 was further brought into contact with the indoor surface thereof. In the three-layer state, it is characterized by a lower frame of a hinged door made of a composite of a bent stainless steel thin plate fixed by screws 21 and an extruded mold material.

(Effects of the Invention) Since the lower frame of the hinged door made of the composite material of the stainless steel thin plate and the extruded mold material of the present invention has the above-mentioned structure and function, it is the first invention in the assembling. In this case, the upper edge 34a of the mounting rib 34 of the lower frame body B and the upper surface 20a of the seal mounting member D are brought into contact with the lower surface of the horizontal web 35a of the cut-off edge 35 to easily and quickly seal. The mounting member D can be positioned in a fixed position, and in the second aspect of the invention, the positioning is performed by aligning the long groove 19e on the lower surface of the joining rib 40 of the mounting member D with the mounting rib of the lower frame body B. This is made possible by fitting it to the upper edge 37a of 37, and in addition, since the joining rib 40 is fixed in the three-layer state of the mounting rib 37 and the parting edge 35, compared to the case where it is screwed into the tap of a single thin plate. Since the receiving thickness of the screw part of the screw is long and it works effectively, it is not affected by the impact when opening and closing the hinged door 2. Therefore, loosening of screws can be reduced.

Even if the mounting part of the sealing material, which was found in the lower frame of a metal sash that is only made of a bent stainless steel thin plate, is formed in a complicated shape, the sealing function can still be fully functioned. However, due to the limitation of the processing accuracy of each component due to bending work, it was not possible to obtain a high degree of airtightness, watertightness and soundproofing performance, whereas an integrally molded seal made of an extruded aluminum alloy material. By disposing the mounting member on the lower frame made of a bent stainless steel thin plate, a sufficiently high sealing effect relating to the above performance can be realized in the product of the present invention. By using it, the function of the metal sash in the airtight and watertight hinged door is further enhanced, and its production cost is also considerably higher than that when the aluminum profile was coated with stainless steel like the conventional product. It is possible to lower the reduction.
