Description

Hollow panel type lightweight wood canvas frame {HOLLOW PANELED LIGHTWEIGHT WOOD CANVAS FRAME}

The present invention relates to a canvas frame. More specifically, it is used by tensioning and fixing the edges of a canvas used for painting in a studio, etc., and is a hollow panel-type lightweight wood that is light and strong as a panel type, easy to manufacture, and inexpensive to manufacture. It's about the canvas frame.

When painting Western paintings or oil paintings, canvas, a type of special fabric, is used. CANVAS is a woven paper used to make sails, tents, backpacks, etc., or to paint oil paintings in art studios. The four sides of the canvas are tensioned using a tensioning device, and then wrapped around a canvas frame and secured by fixing members such as thumbtacks and tacks. It is used in fixed connection, and a picture is drawn on the canvas in this state.

Canvas frames are generally made of thick boards made of wood such as solid wood or MDF, or by fastening a straight or cross-shaped reinforcement frame to the inside of a square frame as shown in Figure 1a. However, conventional wooden canvas frames are the main cause of discoloration of canvases or paintings due to external environmental changes such as temperature, moisture, and mold, and the frames are easily warped or brittle, reducing durability, and are made of solid wood or MDF, making them heavy. There is a problem that it is heavy and increases manufacturing costs.

In addition, the conventional wooden canvas frame has a cumbersome manufacturing process because various fasteners and fixing screws are used to fasten between unit frames forming a square frame, and the various fasteners and fixing screws are exposed to the outside, resulting in a poor appearance. When connecting a cross-shaped reinforcement frame, the production and processing of the reinforcement frame and processing of the fastening area are required, making the manufacturing and processing process difficult, and the bearing capacity against external shocks is also weak.

In addition, when conventional canvas frames are manufactured in various shapes such as circles, ovals, and polygons rather than square frames, the manufacturing process is cumbersome because the canvas frames, reinforcement frames, and various fasteners that fit the shapes must be manufactured and processed separately. It takes a lot of manufacturing time and cost, and there is a problem of low productivity.

Meanwhile, in Patent Document 1, as a related prior art, it is made of a metal material as shown in FIG. 1b, is provided with a square frame, has a front surface, a back surface, and an inner surface and an outer surface between the front and the back, and at least a portion of the front and outer surfaces are tensile. a first frame provided to contact the rear surface of the bent portion of the canvas; and a second frame made of wood, coupled to at least a portion of the back of the first frame, and provided to fix the edge of the canvas.

However, since the above-described prior art uses a second frame made of wood such as solid wood or MDF by combining it with a first frame made of metal, the problems of the above-mentioned wood frame still exist, and the manufacturing and processing process is complicated. There is a problem that manufacturing time and manufacturing cost increase, and the bonding strength of the first and second frames decreases and they can be easily separated, which may reduce durability.

In addition, in Patent Document 2 as a prior art, in constructing a canvas frame made of metal as shown in Figure 1c, a fixture coupling groove is formed on the inside of the inclined surface of the front, the center of the back and bottom are opened, and wooden latches and fastener latches are provided on both sides. Both ends of the profile made of aluminum extrusion material that protrudes and has a wood fixing groove and a fastening guide groove on the inside are cut at 45 degrees, and each wood is made with a rectangular cross-section, and both ends of the canvas fixing wood corresponding to the wood fixing groove are cut at 45 degrees. In a canvas frame in which the canvas fixing wood is exposed to the outside by cutting it and inserting it into a wood fixing groove and connecting it with a fixture, both sides of the input piece protrude at 90 degrees and a tie device with steps on both ends of the input piece. A canvas frame assembled by inserting pieces into the tie guide grooves of horizontal and vertical profiles and tightening support bolts has been revealed.

However, the above-described prior art requires a large number of metal fastening means such as fasteners and support bolts to fasten the reinforcement frame, increases the number of joints, increases the weight of the frame, and reduces productivity due to cumbersome work. There is a problem that the cost increases and the fastening means is exposed to the outside, resulting in poor appearance.

Hereinafter, specific details for implementing the hollow panel type lightweight wooden canvas frame according to the present invention will be described in detail with reference to the drawings.

The hollow panel-type lightweight wooden canvas frame (1) according to the present invention is used by tensioning and fixing the edges of the canvas used for drawing in art studios, etc., is light and strong, has an easy manufacturing process, and has a low manufacturing cost, and has a front panel (100 ), a rear panel 200, a hollow portion 300, a support piece 400, an outer edge neck 500, and an inner edge neck 600.

Referring to FIGS. 2A to 3B, the front panel 100 is made of wood, has a front hole 110 formed through the inner center, and is attached to a plurality of support pieces 220 with an adhesive.

The rear panel 200 is made of wood, is disposed at the rear of the front panel 100, is attached to a plurality of support pieces 220 with an adhesive, and a rear hole 210 is formed through the inner center to form a front panel 100. It may be formed to communicate with the front hole 110 of the panel 100.

At this time, when the canvas frame 1 is circular, oval, or polygonal, the front panel 100 and rear panel 200 are also circular, oval, or polygonal, respectively, and are formed into a front hole 110 and a rear hole depending on their external shapes. (210) is also made of a circular, oval, or polygonal shape.

The areas of the front hole 110 and the rear hole 210 may be 1/9 to 1/3 of the area of the front panel 100 and the rear panel 200, respectively, and if the area is less than 1/9, the hole size Because it is small, it is difficult to grip and ventilation is poor, and if the area exceeds 1/3, the bearing capacity may be weakened.

In addition, the front panel 100 and the rear panel 200 may be made of a thin veneer plate, and the thickness may be 1 to 5 mm.

Conventional wooden canvas frames used thick boards made of wood or MDF, or by fastening straight or cross-shaped reinforcement frames to the inside of a square frame made of wood or MDF. Wood or MDF is expensive, heavy, and has high temperature and humidity. It can be easily distorted or deformed by other factors, and as the moisture contained in the wood or MDF is released, mold can form on the canvas frame or painting, and the support capacity against external shock is not sufficient.

However, the canvas frame (1) of the present invention does not use the expensive wood or MDF described above, but uses a front panel (100) and a rear panel (100) made of thin veneer on the front and rear, thereby significantly reducing the cost and weight. It is composed of a pair of plates at the front and rear and is firmly supported by a plurality of support pieces 400 between them, so it is not easily distorted or deformed by temperature or moisture, and moisture generated from solid wood or MDF is discharged. It is possible to secure sufficient support against external shocks while preventing mold from occurring.

In addition, the front panel 100 has a front hole 110 formed at the inner center, and the rear panel 200 may also have a rear hole 210 formed at the inner center depending on the embodiment. The formation of (110) or the rear hole (210) provides good ventilation and is less affected by temperature, moisture, and mold, resulting in excellent durability, excellent picture preservation, and lighter weight. In addition, the conventional canvas frame does not have a separate means of holding, so it is carried in an unstable state by holding the corners of the canvas with both hands or one hand. The larger the size of the canvas frame, the lower the transport safety. However, the canvas frame 1 of the present invention can be safely and easily transported by holding it through the front hole 110 or the front hole 110 and the rear hole 210.

The hollow portion 300 is formed as an empty space between the front panel 100 and the rear panel 200, and is an empty space closed on all sides by the outer edge neck 400 and the inner edge neck 500, which will be described later. is formed by As a result, the weight is significantly lighter than that of conventional wooden canvas frames or metal canvas frames made of solid wood or MDF, and since the interior is empty rather than filled with wood, it is less affected by temperature, moisture, and mold, and has excellent durability. Preservation is also excellent.

Referring to FIG. 6, the plurality of support pieces 400 are made of wood, are formed in the hollow portion 300, and are attached to the front panel 100 and the rear panel 200 with an adhesive to form the front panel. Supports (100) and rear panel (200). At this time, the front plate 100 and the rear plate 200 may have a front hole 110 and a rear hole 210 formed through each of the inner centers, so the plurality of support pieces 400 are formed through the front hole 100 and the rear plate 200. It is formed around the outer perimeter of the rear hole 210, that is, between the outer edge neck 500 and the inner edge neck 600, whereby the plurality of support pieces 400 connect the front panel 100 and the rear panel 200. It is a more solid support. This support piece 400 can be made by using wood chips discarded during processing work such as cutting wood in a woodworking shop or canvas frame manufacturing plant, thereby significantly reducing costs.

In this way, the plurality of support pieces 400 in the hollow portion 300 support the front panel 100 and the rear panel 200, so that it is not easily distorted or deformed by temperature, moisture, or external shock, making it lightweight and more robust.

Referring to Figure 6, the outer edge wood 500 is made of wood, and is attached to the front panel 100 and the rear panel 200 by adhesive along the edge between the front panel 100 and the rear panel 200. It is attached to and supports the outer edges of the front panel 100 and the rear panel 200.

Referring to FIGS. 5A and 5B, the inner edge wood 600 is made of wood, and is attached to the front panel 100 by adhesive in the hollow portion 300 between the front panel 100 and the rear panel 200. It is attached to the rear panel 200 and is formed along the perimeter of the front hole 110 to support the inner edges of the front panel 100 and the rear panel 200.

When the canvas frame 1 is circular, oval, or polygonal, the outer edge neck 500 and the inner edge neck 600 are also made of circular bands, oval bands, or polygonal bands, respectively. At this time, the outer edge tree 500 and the inner edge tree 600 may be formed as one piece, or may be formed by connecting several unit trees.

The width of the outer edge neck 500 and the inner edge neck 600 may be 1 to 2 cm, and the thickness may be 2 to 3 cm.

In this way, the outer edge and inner edge of the canvas frame 1 are supported by the outer edge neck 500 and the inner edge neck 600, respectively, and the space between them is supported by a plurality of support pieces 400, making it strong. It is sturdy as it is not easily distorted or deformed by external shocks, and a front panel (100) and a rear panel (200) are attached to the front and rear of the outer edge neck (500) and the inner edge neck (600), respectively, so that it is protected from the external environment. Accordingly, damage to the picture can be prevented by blocking moisture discharged from the outer edge tree 500 and the inner edge tree 600. In addition, the outer edge wood 500 and the inner edge wood 600 use inexpensive square wood such as suede wood, which can significantly reduce costs compared to conventional solid wood or MDF frames.

The support frame 700 is attached with an adhesive along the front edge of the front panel 100 and is tensioned tightly to support the fixed canvas C and prevent the canvas C from directly contacting the front panel 100. In order to minimize the influence of wood, it is made of wood, and when the canvas frame 1 is circular, oval, or polygonal, the support frame 700 is made of a circular frame, oval frame, or polygonal frame, respectively.

The support frame 700 is formed with an inclined surface 720 that slopes downward toward the inside, and is formed flat on the outside of the inclined surface 720 to form a support surface 710 with which the canvas C comes into contact.

That is, the support frame 700 is provided with a support surface 710 with a flat front surface, and supports the tightly tensioned and fixed canvas C, thereby preventing the canvas C from sagging and tilting downward toward the inside. A photo inclined surface 720 is formed to minimize the area in contact with the canvas (C) and prevent it from interfering with the painting work.

In addition, the canvas frame (1) of the present invention is attached and assembled with adhesive without various fasteners or fixing screws, so various fasteners or fixing screws are not exposed to the outside, and there is no need to manufacture and fasten a reinforcement frame like a conventional canvas frame. And the processing process is easy, and the appearance is neat and excellent.

In addition, referring to FIGS. 7A to 7C, the canvas frame 1 may be circular, oval, or polygonal.

When conventional canvas frames are manufactured in various shapes such as circles, ovals, and polygons rather than square frames, the manufacturing and processing of the canvas frames, reinforcement frames, and various fasteners that fit the shapes must be done separately, making the manufacturing process cumbersome and shortening the manufacturing time. However, the canvas frame of this product can be easily manufactured with only the front and rear panels on both sides and the inner and outer edges and support pieces between them, so it can be manufactured in various shapes such as circular, oval, and polygonal. It is easy to manufacture, and assembly using adhesives is simple, so productivity can be increased. In particular, when manufacturing a circular or oval canvas frame or a large canvas frame, it can be manufactured easily, inexpensively, and robustly.

Meanwhile, referring to FIG. 8, when the canvas (C) is fixed to the canvas frame (1) according to the present invention described above, the back of the canvas frame (1) is pulled with the canvas (C) tensioned by a tensioning device (not shown). Bend the canvas (C) and fix it to the rear panel 200 or the rear panel 200 and the outer edge tree 500 using fixing members such as thumbtacks, iron cores, fixing pins, and tacks. Since fixing the canvas using these fixing members is a well-known technique, detailed explanation will be omitted.

In other words, the canvas (C) is placed so that the surface on which the picture is drawn faces the front, and the opposite side faces the back. In this state, the edge of the canvas (C) is stretched and bent twice toward the back. If so, the edge of the canvas (C) comes into contact with the rear edge of the rear panel (200) through the support frame (700) and the outer edge neck (500), and in this state, fixing members such as thumbtacks, iron cores, fixing pins, and tacks are attached. Fix the canvas (C) to the rear panel 200 or the rear panel 200 and the outer edge tree 500.

In the end, the hollow panel-type lightweight wooden canvas frame (1) according to the present invention is strong because the front and rear panels on both sides are supported by the inner and outer edge trees and support pieces, and is sturdy as it is not easily twisted or deformed by external shocks, Manufactured as a panel type with a hollow and perforated structure without using wood or MDF, it is well-ventilated and less affected by temperature, moisture, and mold, so it is durable, has excellent picture preservation, is light in weight, and has low manufacturing and processing costs. It is attached with adhesive without various fasteners or fixing screws, and the manufacturing and processing process is easy as there is no need to manufacture or fasten a reinforcement frame. Productivity is increased due to simple assembly. It has a clean and excellent appearance, and comes in various shapes such as round, oval, and polygon. The shape is easy to manufacture, and it can be safely and easily transported by holding it through the front or back hole.
