Description

[Detailed description of the invention] (Industrial application field) This invention is applicable to various types of devices that are used indoors, etc., such as closet fittings, mirror panels for storage cabinets, sliding doors, etc., where only the front side is always decorative and the back side is not decorated. This relates to one-sided picture frame attachment used for fittings, etc.

(Prior Art) Single-sided picture frames for various types of fittings and the like are generally used only for expensive products because the manufacturing process is complicated and time-consuming. Another drawback was that several types of picture frames were manufactured to correspond to the thickness of the fittings. Furthermore, since the single-sided picture frame is attached by nailing or screwing the frame from the surface, the nails, screws, etc. may be exposed on the surface or cracks may occur due to nailing, resulting in very unsightly defects. There were drawbacks such as screws loosening and coming off or popping out.

(Problem that the invention attempts to solve) In single-sided picture frames used for various fittings, etc.
Not only is it necessary that the pelmets attached to the fittings can be reliably installed with a simple frame assembly process, but it is also necessary that the pelmets and the frame can be attached more easily than the top plate, regardless of the thickness of the fittings. be. However,
At present, there is no single-sided picture frame attachment that satisfies these demands, and its appearance is desired.

This invention is proposed in response to the above-mentioned demands.

(Means for Solving the Problems) In order to solve all of the above-mentioned problems, the single-sided picture frame attachment of this invention constitutes a picture frame body with an external frame 2 and an internal frame 3 made of low-foam polystyrene or the like. Forming an opening 4 in which a decorative plate 8 is pasted on the front plate of a fitting consisting of a front plate 6 and a back plate 7,
The internal frame 3 having a substantially U-shaped cross section and consisting of a long piece 13 and a short piece 14 provided with a locking piece 12 and a receiving protrusion 15 is attached to this opening 4. This receiving protrusion 1
The above purpose is achieved by fitting the decorative plate 8 such as a mirror plate or shutter to the inner frame 5, and fitting the outer frame 2, which has a substantially E-shaped cross section and is provided with a press-contact protruding strip 9, to the inner frame 3. We are planning to achieve this goal.

(Embodiment) Hereinafter, an embodiment of this invention will be described with reference to the drawings.A frame main body 1 is composed of an external frame 2 made of low-foam polystyrene in the longitudinal direction, and an internal frame 3 that fits oppositely.

Next, the external frame 2 is provided with pressure welding projecting strips 9, 9 for pressure welding, whose corners are inclined in the longitudinal direction and whose surfaces are provided with an inclined pattern, protrudingly provided on both the outside, and on the inside. The insertion protrusion 10 is formed into an integral E-shaped cross section. The insertion protrusion 1
0 is formed with a chevron-shaped locking protrusion 11 that locks on one of its tips. The internal frame 3 has a substantially U-shaped cross section, and a locking piece 12 bent outward is formed at one end of a long side 13 thereof. Further, on the short side 14 of the internal frame 3, a receiving protrusion 15 is formed toward the center of the outside to receive various decorative plates 8, and an engaging portion that engages with the locking protrusion 11 is formed on the inner side of the tip. 16 is formed in a protruding manner.

Next, the fitting 5 is constructed by bonding a front plate 6 and a back plate 7 on the front and back sides of various core bodies 18 inside, and the opening 4 is formed in the front plate 6 in an appropriate shape or size. It has been done. Reference numeral 17 indicates a nail for driving the inner frame 3 onto the core body 18.

(Function) To explain how to assemble this invention, in order to attach the single-sided picture frame main body 1 to the surface of the fitting 5 shown in FIG. 1, the opening 4 is bored only in the surface plate 6 of the fitting 5. As shown in FIG. 4, the long sides 13 of the internal frame 3 and the locking pieces 12
and are brought into contact with the edge of the opening and fixed with nails 17. Next, a glass plate previously formed as a decorative plate 8, various panels, shutters, etc. are fitted onto the receiving protrusion 15 of the internal frame 3. Next, when the insertion protrusion 10 of the external frame 2 is pushed in from the outside of the internal frame 3, the locking protrusion 11 at the tip engages the short side 14.
After the engaging portions 16 are temporarily pressed and deformed, they are restored and engaged, and each decorative plate 8 is clamped and fixed between the inner frame 3 and the outer frame 2.

In addition, according to the single-sided picture frame, if the thickness of the fittings 5 made of wood or the like is large, the space between the back plate 7 and the decorative plate 8 will only be large, and it can be freely attached to fittings of various thicknesses. It can be used.

(Effect of the invention) As mentioned above, this invention is an excellent method that allows a single-sided picture frame to be constructed by simply fixing the internal frame to the opening of the fittings, etc., and fitting the external frame from the side of the internal frame. It has a practical effect, and because nails are driven into the core from inside the inner frame and not into the outer frame, there are no nails or screws exposed on the surface of the frame, resulting in a very beautiful finish. be. The locking pieces and the receiving protrusions provided on the internal frame can stably abut against the opening, and the receiving protrusions can reliably and stably support the decorative plate. This has an unprecedented convenient effect in that the locking piece of the internal frame allows it to be freely used for various types of fittings having different thicknesses. Furthermore, by using an external frame in which the insertion protrusion and the press-contact projection strip are integrally molded, the inner frame can be reliably fitted from the outside, and the insertion protrusion can securely lock the inner frame, making it easy to use. There is an effect that there is no fear of separation, and an excellent effect that the decorative plate is reliably pressed and clamped by the press-contact protruding strip. Furthermore, since the external frame and internal frame are made of low-foam polystyrene, etc., they are easy to cut, and each decorative plate is held in place as a buffer to prevent damage, cracks, corrosion, etc., and unlike wooden frames, it can be painted. It has the effect that it is not necessary.
