Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a structure for attaching a decorative frame to a door in which the decorative frame is recessed into a groove formed on the door surface. [Prior art and problems to be solved by the invention] Today, as a method of attaching a decorative frame to the door surface,
Some doors have grooves formed on the surface of the door, into which the legs of the decorative frame are inserted. In this case, the fixing member on which the engaging part is formed is fixed in the groove in advance, and the decorative frame is forcibly pushed in so that the engaging part provided on the decorative frame side is engaged with the engaging part on the fixed member side. There are some that are installed together. However, in this case, if the fixed member side engaging portion is continuous over the entire length of the groove,
There is a drawback that the press-fitting operation of the decorative frame is troublesome and complicated, and the workability is extremely poor. Therefore, it has been proposed to improve workability by distributing fixing members at appropriate intervals and engaging and attaching decorative frames to these fixing members. However, if this is done, the decorative frame may not be supported in places where there is no fixing member, and the decorative frame may sink deeply into the groove and bend in a wave-like manner.To avoid this, ,
When the legs of the decorative frame are lengthened and installed in the groove,
It is necessary to support the decorative frame so that it does not inadvertently sink in by placing the end of the leg in contact with the bottom of the concave groove, but in this case, the decorative frame must be made of more raw material to compensate for the length of the leg. As a result, a new problem arises in that material costs increase and cost increases are unavoidable. [Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a mounting structure for a decorative frame on a door that can eliminate these drawbacks. In order to install the decorative frame by sinking it into a groove formed on the surface, the groove is formed with tapered side surfaces so that the inner diameter is wider on the opening side than on the groove bottom side, and the groove bottom of the groove is For this, the fixing metal fittings on which the engaging parts are formed are fixed integrally with an appropriate interval, while for the decorative frame, the decorative frame is forcibly pushed in to engage with the engaging parts on the side of the fixing metal fittings. A leg portion provided with an engaging portion is formed, and the outer surface of the leg portion is further brought into contact with the tapered side surface of the groove in a state where a decorative frame in which both engaging portions are engaged with each other is attached. The present invention is characterized in that the decorative frame is configured as a restricting portion that restricts the decorative frame from sinking into the groove any further. With this configuration, the present invention makes it possible to stably support the decorative frame without making the mounting legs particularly long, even when the decorative frame is attached to a structure in which fixing fittings are scattered in the groove. This is what I did. [Example] Next, an example of the present invention will be described based on the drawings. In the drawings, 1 is a steel door, and a groove 3 is formed in a surface plate 2 of the door 1 , so that a decorative frame 4 can be inserted into the door 1. Here, the groove 3 has tapered side surfaces such that the inner diameter is wider toward the opening side than the groove bottom side, and mounting holes 8 are bored at predetermined intervals at the groove bottom side. There is. Reference numeral 5 denotes a fixture made of a highly elastic member such as metal;
is integrally fixed in the mounting hole 8 using a fastener such as a tap rivet 6, and the fixing metal fitting 5 has a flat part 5' that comes into contact with the bottom surface of the groove;
A rising portion 5'' protrudes from both side edges of the flat portion 5' toward the opening side, and an engaging portion 5 that is bent into a convex shape toward the side surface of the groove at the upper end of the rising portion 5''. It is structured accordingly. On the other hand, the decorative frame 4 includes a flat part 4 that is substantially flush with the door surface when attached, both legs 4' hanging down from the flat part 4, and a part protruding from the inner edge of the lower part of the legs 4'. Several decorative V-grooves 4'' are formed on the upper surface of the flat part 4 . The distance (inner dimension) l between the mating parts 4'' is set to be slightly narrower than the outer dimension l' between the engaging parts 5 of the fixing fitting 5 (l<l'). Then, the decorative frame 4 is forcibly pushed into the inner cavity 7 formed between both legs 4' and whose lower side is open, so that the decorative frame side engaging part 4'' exceeds the fixing metal side engaging part 5. By doing so, the leg portion 4' is installed in a state where it is sunk into the groove 3, but in this state of installation, the outer surface of the leg 4' comes into contact with the tapered side surface of the groove 3, preventing it from sinking any further. It becomes the regulation part that is regulated, and the decorative frame 4
The structure is designed to support the following. In the embodiment of the present invention configured as described above, the decorative frame 4 is forcibly pressed into engagement with the fixing fittings 5 fixed to the groove 3 at an appropriate interval. In this installed state, the legs 4' of the decorative frame 4 are wider on the opening side than on the groove bottom side of the groove 3. By coming into contact with the tapered side surface, the decorative frame 4 is prevented from entering the groove 3 more than necessary even in areas where the fixing member 5 is not provided. Therefore, even if the decorative frame 4 can be simply and easily assembled by forcibly fitting the fixing metal fittings 5 scattered at appropriate intervals, the fixing metal fittings 5 are There is no need to construct a support for regulating immersion in areas where there is no immersion in the groove 3 by making the legs 4' long so as to bring them into contact with the groove bottom of the groove 3 and stably supporting them as in the conventional case. The decorative frame 4 can be supported by effectively utilizing the tapered side surface of the decorative frame 4. Therefore, the decorative frame 4 is short enough for the engaging portion 4'' to engage beyond the fixed member side engaging portion 5. The leg portions 4' are sufficient, and an inexpensive decorative frame 4 with fewer raw materials can be used, contributing to cost reduction. [Function and Effect] In summary, the present invention is constructed as described above. Therefore, the decorative frame is installed by forcibly engaging the fixing metal fittings fixed in the groove in advance so that the legs fit into the groove, but the fixing metal fittings are scattered and fixed in the groove, making it easy to attach the decorative frame.Furthermore, in this installed state, the outer surface of the leg of the decorative frame touches and supports the tapered side surface of the groove. Therefore, in cases where fixing metal fittings are scattered, the decorative frame will be prohibited from sinking deeper into the groove inadvertently in areas where there are no fixing metal fittings. There is no need to lengthen the legs and make them contact the bottom of the groove to avoid the possibility of damage.As a result, it is possible to use a decorative frame that uses less raw material, eliminating waste and reducing costs. This will also contribute to downtime.
