Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a canvas frame for producing a painting canvas by stretching canvas cloth.

(Prior art) Conventionally, frames with rectangular cross sections are arranged on all four sides to form a frame, the surface of this frame is covered with canvas cloth, and this canvas cloth is fixed to the outer surface of the frame material with nails, etc. It was set up.

(Problem that the invention aims to solve) For this reason, the canvas cloth was fixed to the outer circumferential surface of the frame with nails, etc., but the heads of the nails protruded and could get caught when stored in the frame. It is difficult to insert and may damage the frame. Additionally, nail heads often catch hands and fingers, causing injuries.

Moreover, it is inferior in appearance and does not look good.

Furthermore, since the outside surface of the frame of the canvas frame is flat, the outside surface of the frame is in close contact with the outside surface of the frame, and while holding the nail with your thumb and forefinger, the tip of the nail is inserted into the canvas fabric. I needed to type it in. As a result, workers may hit their fingers with the hammer and injure themselves.

Also, ideally, the canvas frame should be stretched with stronger canvas cloth.

Therefore, the object of the present invention is to provide a canvas frame that allows the canvas cloth to be stretched with sufficient force without the nail heads protruding from the outside surface of the canvas frame. shall be.

(Means for Solving the Problems) This invention has the following configuration in order to solve the above problems. In a canvas frame in which canvas cloth is stretched on the front side and the peripheral edge of the canvas cloth is fixed to the outside surface of the frame with nails, etc., the rear side of the outside surface of the frame is set back inward from the front side of the frame. It is characterized in that the rear side surface is formed into a nail-fastening part.

Further, the nailing portion may be formed on an inclined surface toward the inside of the frame as it approaches the back surface. Furthermore, the nailing portion may be formed on a stepped surface that recedes inward from the front side surface of the outer surface of the frame.

(effect) Next, we will discuss the effect.

Wrap the canvas cloth so that it covers the surface of the canvas frame. Then, fold the canvas cloth at the front corner of the canvas frame, pinch the canvas cloth with a tool such as pliers, and pull it toward the back side of the canvas frame.

In this state, nail the canvas cloth to the nailing part.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

The canvas frame 12 is constructed by arranging frames 24 on four sides.

The frame 24 has a substantially rectangular cross-sectional shape with an upper surface having an inclined surface 26 that gradually descends toward the inside of the canvas frame 12. Outer surface 14 of frame wood 24
A bending portion 28 for bending the canvas cloth 10 is formed in an arc shape at the upper edge of the holder. Also, frame wood 24
The outer surface 14 of is formed with a front side surface being a vertical surface,
A rear side surface extending from the middle part toward the back surface 16 is formed into a nailing part 18 that gradually slopes toward the inside of the canvas frame 12.

An arcuate boundary portion 30 is formed at the boundary portion of the nailing portion 18 on the outer surface 14 of the frame 24.

Next, a procedure for stretching the canvas cloth 10 on the canvas frame 12 will be described.

The canvas cloth 10 is wrapped so as to cover the surface of the canvas frame 12.

The canvas cloth 10 located on one side of the canvas frame 12 is bent at the bending part 28 of the frame 24 to cover the outer surface 14.

Then, the peripheral edge of the canvas cloth 10 is pinched with a tool such as pliers and pulled in the direction of the back surface 16 (downward). At this time, the nailing part 18 and the canvas cloth 10 are left slightly apart (see FIG. 1).

In this state, the nail 20 is attached to the canvas cloth 10.
pierce the tip of the nail 20 to support the nail 20.

Subsequently, the head 22 of the nail 20 is hit with a hammer, and the nail 20 is driven in so that the head 22 of the nail 20 is flush with the nail fixing part 18. Therefore, the head 22 of the nail 20 is located inside the canvas frame 12 from the outermost protruding portion of the outer surface of the frame 24 of the canvas frame 12.

At this time, since the nails 20 are driven along the slope of the nailing portion 18, the canvas cloth 10 is fixed in a manner that it is slightly pulled downward.

Therefore, the canvas cloth 10 is stretched under even stronger tension, and the tension of the canvas cloth 10 is promoted.

Thereafter, in the same manner, apply 10 pieces of canvas cloth to each frame 24.
The canvas cloth 10 is stretched by fixing the peripheral edge of the canvas cloth 10 with nails 20.

Note that the canvas cloth 10 is attached to the bent portion 28 of the frame 24.
The canvas cloth 10 may be brought into close contact with the nailing portion 18 when the canvas cloth 10 is bent at the back side 16 and pinched with a tool such as pliers in the direction of the back surface 16 and pulled downward.

FIG. 3 shows another embodiment.

A step 32 is formed at a boundary 30 in the middle of the outer surface of the frame 24 constituting the canvas of this embodiment. Following this step 32, a nailing portion 18 is formed as a step surface. The nailing portion 18 is an inclined surface on the rear side surface of the outer surface that gradually moves inward of the canvas frame 12 as it goes toward the back surface 16.

In the embodiment shown in FIG. 3, the canvas cloth 10 can also be nailed in the same manner as in the above embodiment.

In particular, the canvas cloth 10 is
When the canvas fabric 10 is folded with a tool such as pliers and pulled diagonally downward inside the canvas frame 12 (toward the upper left in FIG. 3), the canvas fabric 10 does not come into close contact with the frame 24 at the step 32. It will be in a floating state. In this state, when the nail 22 is driven in, the canvas cloth 10 comes into close contact with the outer surface 14 and is pulled under even stronger tension, thereby promoting tension.

Also, since the canvas cloth 10 is raised at the step 32 (the canvas cloth 10 is not in close contact with the step 32), the tip of the nail 20 is pierced into the canvas cloth 10 at this raised portion to support it. You can also do that.

Although various explanations have been given above with reference to preferred embodiments of the present invention, it goes without saying that this invention is not limited to the above-mentioned embodiments. Of course, many modifications can be made without departing from the spirit of the invention, such as changes to the following.

(Effects of the invention) Since the present invention is configured as described above, it achieves the following remarkable effects.

(1) A nailing part that recedes inward of the canvas frame is formed on the rear side of the outer surface of the canvas frame, and a nail is driven into this nailing part, so that the head of the nail protrudes from the outermost part of the canvas frame. It does not protrude laterally than the part. Therefore, it is easy to store the canvas frame in the frame.

(2) Furthermore, since the nailing portion is formed to be set back inward of the canvas frame, the peripheral edge of the canvas cloth does not protrude laterally. In particular, by forming the nailing portion into an inclined surface that slopes inward of the canvas frame, the peripheral edge of the canvas cloth can be directed inward.

(3) When nailing the outside of the canvas frame,
It is also possible to raise the canvas cloth from the nailed part, temporarily fix it by piercing the canvas cloth in this part, and then drive the nail in this state.
Therefore, there is no need to support the nail with the finger, and there is no possibility of accidentally hitting the nail with the hammer.

(4) Also, by driving the nail with the canvas cloth slightly lifted from the nailing part, the canvas cloth can be pulled even further toward the back of the canvas frame, and the canvas cloth can be stretched even more tightly. can do.

(5) Furthermore, when looking at the canvas frame from the front, the nails on the outer surface of the canvas frame are not visible, so it can be displayed as is.
