Abstract

(57) [Summary] [Purpose] To provide a large frame that is less affected by distortion even in hot and humid environments. [Structure] On the back surface of a front frame 1 formed into a rectangular shape by abutting 45 degree cuts, an inner frame 2 cut out from one board is formed with an inner method larger than the inner method of the front frame 1. The poster 7 and the like are housed in a state in which the poster 7 and the like are sandwiched between the transparent panel 4 on the front side and the back plate 5 on the back side in a frame laminated so that the stepped portion 3 is provided along the.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a large frame for accommodating a poster or the like and displaying it on a wall or the like, and particularly to a large frame of a wooden frame type that can match any place without any discomfort and feel even warmth.

[0002]

[Prior art]

 As shown in FIG. 5, the large-sized frame has a rectangular shape in which a long member 8 having a step portion 3 is butted with 45 degree cuts, and the step portion 3 has a lower step along the inner surface of the back surface. The frame was framed and a transparent panel 4a such as glass or an acrylic plate was fitted using the stepped portion 3 and a poster 7 or the like was adhered to the back surface of the transparent panel 4a and pressed and fixed by the back plate 5.

[0003]

[Problems to be solved by the device]

 Due to the high humidity in Japan, a large wooden frame is prone to warping and bending, which makes it difficult to bend, causing the butted parts to separate and lose shape, the transparent panel to tilt, and the poster inside to slip. It was easy. Also, if the abutting parts are separated, even the poster itself will be inferior, and the value of even the attractive masterpiece will be halved. It is possible to cut out a frame from a single log if it is a small tabletop, but if it becomes large it is difficult to secure a large amount of huge log that can be used for it, and that much distortion Is likely to be affected, and cracks may appear and the appearance may be impaired.

[0004]

[Means for Solving the Problems]

 INDUSTRIAL APPLICABILITY The present invention is a large frame having a frame structure that does not easily get out of order, and the frame is a middle frame formed by cutting out from one board on the back surface of the front frame with an inner method larger than the inner method of the front frame. Are integrally joined. Here, the board means a flat plate, and does not matter the material.

[0005]

[Action]

 Since the inner frame cut out from one board does not easily deform, the wooden frame to which the inner frame is attached is prevented from being deformed by the reinforcing effect of the inner frame, and the front frame and the inner frame are Are integrated to increase the heaviness.

[0006]

【Example】

 A large frame according to the present invention will be described with reference to the drawings. Reference numeral 1 denotes a wooden front frame, which is formed by cutting a long plate with a width of about 30 mm so that the edges have 45 degree cuts, and combining the cuts with each other vertically and horizontally to form a rectangle. . Reference numeral 2 is a middle frame that is integrally attached to the back surface of the front frame. The inner frame is one size smaller than the front frame, and the outer frame is formed to have the same size. Also, the inner frame is cut out from one large chip board and has no seam. A step portion 3 is formed in the inner portion of the frame in which the middle frame is attached to the outer frame.

Reference numeral 4 is a colorless and transparent acrylic plate that is fitted to the frame while being locked to the step portion 3, and 5 is a back plate that is fitted on the acrylic plate 4 in a stacked manner. This back plate 5 is of a size that can be fitted into the middle frame 2 without making any difference in size, and is fixed by rotation type locking pieces 6.6, ... .

The large frame thus formed can be seen through the acrylic plate 4 by inserting the poster 7 and the like between the acrylic plate 4 and the back plate 5. The acryl plate 4 is locked to the step part 3 so as not to fall off to the front side, the back side is pressed by the back plate 5, and the poster 7 housed between them is protected while being extended in the frame. Therefore, you can hang it on a wall without creases or curls and save it in a viewable state.

In the frame of the present invention, the frame is formed by integrally bonding the inner frame which is not deformed to the back of the front frame, so that the inner frame serves as a reinforcement to prevent warping or distortion of the front frame. Properly prevent and prevent deformation even in Japan with high humidity. In the embodiment, since the same abutting surface as that of the conventional frame appears on the front side of the frame, there is no strange impression and it can be accepted without any resistance as a user side.

It should be noted that it is also possible to adopt a cut-out plate from the front plate, a plate with an inclination or engraving, or to add a back frame to the back surface of the middle plate to give it a certain thickness. By stacking and laminating a plurality of sheets, it becomes more resistant to deformation.

Although an acrylic plate that is hard to break is used as the transparent panel in the embodiments, it is possible to use glass, and it is desirable to apply the coating to the entire surface of the frame. From the board with the inner frame cut out, it is possible to cut out a medium frame with a size larger or smaller than that, so there is almost no waste of material.

[0012]

[Effect of device]

 According to the present invention, a large wooden frame which is apt to be out of order as the size becomes larger can be used safely without fear of going out of order even in a place with high humidity or conversely too low.

Claims (1)

[Scope of utility model registration request] 1. An inner frame having a size larger than the inner size of the front frame is provided on the back surface of the front frame, and a step portion is circumferentially provided along the inner direction due to a dimensional difference between the front frame and the inner frame. The transparent panel and the back plate are fitted into the stepped portion from the back side in the rectangular frame joined as described above in a locked state, the back plate is prevented from falling off, and the poster and the like are separated from the transparent panel and the back plate. A large frame that is sandwiched between and accommodated, and is formed by cutting out the middle frame from one board.
