Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretching frame for stretching a canvas such as a painting canvas or a silk screen.

[0002]

2. Description of the Related Art Generally, in order to lay fabric such as painting canvas or silk screen, a plurality of rectangular parallelepiped wooden frame pieces are prepared, and these are combined in a frame shape using a fabric laying frame. I have. This fabric is fastened and stretched so as to be sandwiched between a frame piece combined in a frame shape and a nail driven into the frame piece.

[0003]

Since the above-mentioned conventional fabric-stretching frame is made of wood, it is susceptible to temperature and humidity, and the fabric stretched there may become slack, making it difficult to draw a picture. And in order to assemble a rectangular framework,
It is necessary to form connecting grooves at both ends of each frame piece. However, unless the grooves are formed with high precision, it becomes difficult to make the four corners of the frame at right angles. In addition, since a large-sized cloth overlaid frame is difficult to hold the frame, it is difficult to make the frame by attaching a crosspiece or the like. In addition, nails or the like are directly driven into the fabric laying frame to stretch the fabric, and when used two or three times, the frame has a plurality of holes, and further use is difficult.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fabric covering frame which is more robust and can be easily assembled. It is another object of the present invention to provide a fabric covering frame that can be repeatedly used.

[0005]

Means for Solving the Problems In order to solve the above-mentioned problems and to achieve the object, a fabric stretching frame of the present invention is constituted as follows.

(1) The cloth stretching frame of the present invention comprises a fastening member capable of fastening a fabric and a frame piece covering at least a part of the fastening member so as to be exposed to the outside. An outer frame, a connector for connecting the outer frames to each other to form a framework for stretching the fabric, and a fabric stretched on the framework contacts a front surface of the outer frame. And a projection formed on the front surface of the frame piece in order to prevent the above problem. With such a configuration, it is possible to easily assemble and repeatedly use the apparatus.

(2) The fabric-stretched frame of the present invention has a structure in which the frame pieces of the fabric-stretched frame are connected at a corner portion, and the frame piece itself for assembling a rectangular frame is formed in a straight line. You can do it. Therefore, the shape of the frame piece is simplified, and the manufacture of the frame piece and the obtaining of the fastening member are facilitated.

[0008] (3) In the fabric-stretched frame of the present invention, the frame piece is formed of metal or plastic, so that the volume of the frame piece itself is reduced by increasing the strength of the frame piece.

[0009]

FIG. 1 is a perspective view showing a schematic configuration of a fabric stretching frame according to an embodiment of the present invention.

A fabric extending frame 1 for extending a cloth such as a painting canvas or a silk screen is formed by connecting both ends of outer frames 2 with a connecting member 3 so as to form a frame. . In particular, as shown in FIG. 2, each of the outer frames 2 is formed in a prismatic shape with a notched end, and is a fastening member 21 for fastening the fabric 4, and at least one of the fastening members 21. And a frame piece 22 that covers a portion to be exposed to the outside. In this case, the frame piece 22 has a U-shaped cross section and is bent so that the groove 23 extends in the longitudinal direction, and the fastening member 21 is disposed inside the groove 23. Thus, the entire one side surface 21a is exposed to the outside. In addition,
The fastening member 21 can be disposed in the groove 23 by using, for example, an adhesive or by press-fitting.

The fastening member 21 can be made of wood, rubber, foam, or the like so that the end of the cloth can be fixed with, for example, a nail.

A screw hole 24 is formed at each end of the frame piece 22 so as to mount the connecting member 3, and a surface of the screw member 24 provided in the groove 23 is formed with a screw hole 24. A protrusion 25 is formed along the longitudinal direction so as to be substantially flush with the side surface 21a. In addition, as described above, since the respective ends of the outer frame 2 are connected to form a rectangular frame, both ends of each frame piece 2 have a right angle at the connecting portion between adjacent frame pieces. As shown in FIG. 4, it is cut diagonally.
In this case, the cutting angle may be 45 degrees with respect to the longitudinal direction of the frame piece 22 as shown in FIG. 4 (a), or may be different angles as shown in FIG. 4 (b). It is possible. In addition, if it cuts so that the total cutting angle of both ends may be 90 degrees, a rectangular frame can be assembled using a plurality of outer frames of the same shape.

The frame piece 22 is preferably made of metal or plastic so that the frame formed by connecting the outer frames 2 at a right angle has sufficient strength. The metal is iron,
It may be copper, aluminum or any other similar or composite material. However, in order to increase the strength more than the frame piece of the conventional wooden fabric-stretched frame, the above-mentioned metal is used which is more rigid than wood. In addition, similarly, the above-mentioned plastic has a higher rigidity than wood.

In the present embodiment, the connecting member 3 connects both ends of the outer frames 2 to form a corner portion of a rectangular frame. It is configured in a shape that can maintain the connection. Specifically, it can be configured in an L shape as shown in FIG. 3 (a), or can be configured in a triangular shape as shown in FIG. 3 (b). In addition, the connector 3 has a plurality of screw holes 31 corresponding to the plurality of screw holes 24 formed at both ends of the frame piece 22. By aligning these screw holes 24 and 31 and screwing them together, the connector 3 and the outer frame 2 are connected, and the outer frames are connected.

The connection by the connecting member 3 can be performed on the front side (canvas surface side) or the back side of the outer frame 2. Further, in addition to being provided in the surface area of the corner portion of each outer frame 2, the connecting tool 3 may be provided in, for example, a surface area other than the corner or an outer end surface area of the corner. The connection between the connecting member 3 and the outer frame 2 may be performed by a method other than screwing. As described above, the outer frames are connected to each other at the corners using the connecting tool 3 to assemble a rectangular frame set, and the frame pieces 22 can be formed in a straight line. Therefore, the shape of the frame piece 22 is simplified, and the manufacture or acquisition of the frame piece can be facilitated.

The method of connecting the connecting member 3 and the outer frames 2 may be any other method that can firmly fix the outer frames 2 to each other, other than the above-described method. For example, a connection method using a bolt and a nut may be used. In this method, the screw holes (24, 31) do not need to be female threads because they are fixed by bolts and nuts.

Next, a description will be given with respect to forming a frame by combining the above-described outer frames 2 and stretching the fabric 4 thereon, as shown in FIG.
This will be specifically described with reference to FIGS.

FIG. 5 is a cross-sectional view of the fabric extending frame assembled by connecting the outer frames 2. The fabric 4 is stretched on the fabric stretching frame as shown by a dotted line.

As shown in FIG. 6 (a), the fabric 4 has one side surface 21a which is an exposed portion of the fastening member 21 fitted to the frame piece 22.
Then, it is fixed using the fixing member 5. A fastening member 5 for fastening the fabric 4 has the end of the fabric 4 overlapped with the member to be fastened, and is driven at a predetermined interval from the overlapping portion. Therefore, as shown in FIG. 6A, a nail is used as the fastening member 5. In addition, anything other than nails can be used as the fastening member. For example, a U-shaped driving piece 5a as shown in FIG. 6 (b) is mentioned as a fastening member other than a nail. Furthermore, the fastening member 5 can be used in place of any material that can strike the member to be fastened and can fasten the cloth 4.

The protruding portion 25 creates a space between the cloth 4 to be stretched and the outer frame 2 to prevent contact between the stretched cloth 4 and the surface of the cloth stretching frame. That is, the projecting portion 25 prevents a step from being generated around the outer frame of the stretched fabric 4 due to contact between the fabric and the fabric stretch frame, and prevents the outer frame from hindering when drawing a picture. Can be prevented.

The fastening member 21 is formed so as to substantially conform to the shape of the groove 23 of the frame piece 22. Further, when the fixing member 21 is formed to be larger than the groove 23, for example, it protrudes from the outer surface of the frame piece 22 beyond the groove 23,
When formed to be smaller than the groove 23, it may be formed so as to be recessed from the outer surface of the frame piece 22 or may be formed in a shape that does not match the groove 23. That is, the fixing member 21 may be formed in a shape that does not coincide with the groove 23 as described above, as long as the shape does not significantly inhibit the fixing of the cloth 4. However, do not protrude from both ends of the frame piece so as not to disturb the assembling of the framework.

Further, the member to be fixed is pressed into the frame piece 22 so as not to be displaced when the fabric 4 is stretched, or is bonded using an adhesive. The fixing force due to this press-fitting or the adhesive force of the adhesive used for bonding does not shift the member to be fastened by the force applied when the fabric is stretched, but is removed from the frame piece 22 by applying a larger force. It is better to be able to do it. Thus, the fastening member can be replaced with a new one even if the fastening member 5 is damaged by replacing the cloth 4. That is, the cloth stretching frame can be repeatedly used simply by replacing the fastening member provided in the frame piece 22.

As described above, the frame piece 22 is preferably made of metal or plastic, and has higher rigidity than wood. Therefore, as shown in FIG. 7, the frame piece 22 according to the present invention is different from the outer frame 2a using conventional wood. The outer frame 2 of the preferred embodiment can be formed in a small volume and can be stored without taking up space during storage before assembly.

In the present preferred embodiment, the fastening member 21 is disposed over the entire frame piece 22, but in another preferred embodiment, the fastening member 21 is
If the fastening member 5 that plays a sufficient role to fasten the fastening member 5 can be arranged, the shape of the frame piece 22, the shape of the fastening member 21, and the mode of exposure of the fastening member 21 are limited. Never. For example, the fastening member 21 shown in FIG.
This is a configuration in which it is fitted without extending to both ends of 23. Also, the groove 23 may not be formed over the entire frame piece 22. That is, the groove may be a hole as long as it is provided so that a sufficient fastening member for fastening the cloth can be arranged on the frame piece 22 as described above.
For example, in the outer frame 2 shown in FIG.8 (b), circular holes 23a are formed at regular intervals, and fastening members 21b formed so as to fit into the circular holes 23a are respectively fitted. Such a configuration is also possible.

In the present preferred embodiment, the fabric extending frame is assembled in a rectangular shape, but in other preferred embodiments, the fabric extending frame can be assembled in a shape other than a rectangular shape.

By changing the oblique cutting angle of the outer frame 2 and the shape of the connecting member, the frame can be formed in any shape. For example, a hexagonal framework can be formed by setting the cutting angle to 30 degrees and using a connector suitable for the cutting angle.

[0027]

According to the present invention, it is possible to provide a fabric covering frame which can be easily assembled, can be used repeatedly, and has high strength.
