Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a mounting device for a canvas in a picture frame.

[Prior art]

In conventional devices of this kind, holes for screws were provided in the side wall of the frame frame of the picture frame, the screws were screwed into the wooden frame of the canvas, and the canvas was fixed by tightening the screws, making it easy to install and remove the canvas. It was very cumbersome to operate, required drilling screw holes in the frame, and was unsightly as the screws were visible from the outside.

[Purpose of invention]

This invention solves the above-mentioned drawbacks. It does not require drilling screw holes in the frame frame, and the canvas can be easily attached to the picture frame with one touch. Moreover, it can be held down according to the thickness of the canvas, and it is easy to attach and remove. The object is to provide a mounting device for a canvas in a picture frame.

[Structure of the idea]

That is, the gist of this invention is that the canvas is held down by bending the holding piece of the holding fitting attached to the frame frame.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings.

The frame frame F of the picture frame G has a front wall 2 projecting from the front end of the side wall 1 on which the canvas C is hung, and vertical and horizontal frame frames F, F on the inner surface of the side wall 1, that is, on the side opposite to the side surface of the canvas C. An insertion groove 3 for a connecting fitting (not shown) to be combined is formed. Both side pieces 4 and 5 of this insertion groove 3 are formed into an L-shaped cross section, and each of the protruding ends thereof is a pair of parallel protrusions 4 spaced apart from each other and facing each other so as to form an opening 6 of the insertion groove 3.
a, 5a are formed.

Then, the presser metal fittings 7 are engaged with the pair of projecting edges 4a, 5a, and are attached to several locations of the vertical and horizontal frame frames F, F, respectively, and the front side is latched to the front wall 2 by the presser metal fittings 7. The rear side of the campus C is held down and fixed (Fig. 1).

The holding fitting 7 is formed by press-molding a metal plate, and a pair of latching pieces 9 and 10 are formed by punching and protruding from a metal plate 8 that joins to the side surface of the canvas C, and each of the latching pieces 9 and 10 is It is inserted into the insertion groove 3 and is curved in a hook shape with openings in opposite directions so as to engage the respective protruding edges 4a and 5a on both sides. Further, a bendable elastic presser piece 11 is integrally formed on the same surface as the substrate 8 and protrudes, and the length of the presser piece 11 is set to a size that can accommodate the difference in thickness of the various canvases C. (Figure 2).

Next, the method for attaching the presser metal fitting 7 to the frame frame F is as follows.
As shown by the chain line in FIG. 3, with the presser metal fitting 7 slanted to the direction of the insertion groove 3 of the frame frame F, each of the locking pieces 9 and 10 is inserted into the insertion groove 3 through the opening 6, and each protrusion is inserted into the insertion groove 3. 4a, 5a and rotate the presser metal fitting 7 in a direction perpendicular to the direction of the insertion groove 3 (in the direction of arrow Q), each of the locking pieces 9, 1
0 completely engages and stops on each of the projecting edges 4a and 5a, and the presser metal fitting 7 is fixed. In this case, the presser metal fitting 7 was fitted and fixed in advance at the attachment position of the presser metal fitting 7, but the state of engagement with each of the protrusions 4a and 5a was made to be slidable to some extent, and the presser metal fitting 7 was previously fitted into the open opening 6. Alternatively, it may be positioned by inserting it from the insertion groove 3 before assembling the frame F and sliding it to a predetermined position.

And, the installation method of campus C is frame bone F.
Hang the front side of the campus C on the front wall 2 of the
Fit the presser metal fitting 7 with its side surface joined to the substrate 8, and bend the presser piece 11 of the presser metal fitting 7 that protrudes from the canvas C toward the rear side with your fingers toward the canvas C (in the direction of arrow P in FIG. 1). , press it against the rear surface of Campus C. Thereby, the canvas C is fixed to the frame F while being held between the front wall 2 and the holding piece 11.

In this way, the presser piece 11 of the presser metal fitting 7 is bendable, so it can be bent according to the thickness of the canvas C to be attached, and can be used uniformly for various types of canvases C.

Also, the campus C can be removed by performing the above operation in the reverse order.
Campus C can be easily removed by hooking 1 with your fingers and pushing it back up to its original state. Also, presser metal fitting 7
It can be easily removed by performing the installation procedure in the reverse order.

As shown in FIGS. 4 and 5, a long hole 12 for fixing a screw is provided in the presser piece 11 of the presser metal fitting 7', and after bending the presser piece 11 and pressing it against the rear surface of the canvas C, screw the screw 13. By inserting it into the elongated hole 12 and tightening it to the rear surface of the canvas C, the canvas C can be fixed more firmly and stably.

[Effect of idea]

As explained above, the canvas attachment device for the picture frame of this invention has a pair of protruding edges spaced apart from and facing each other protruding from the frame bone, and a pair of hanging pieces that are latched onto the pair of protruding edges, and a bent piece. Since the rear side of the canvas is held down by a presser metal fitting with a freely protruding presser piece, the presser metal fitting can be easily attached by simply hooking each hooking piece to a pair of projecting edges of the frame. The canvas can be easily attached with one touch by simply bending and pressing the presser piece of this presser metal fitting according to the thickness of the canvas with your fingers, and the canvas is clamped between the front wall of the frame frame and the presser piece of the presser metal fitting. It is stable because it is in a fixed state, and it is firmly fixed without slipping out of the frame.

Additionally, the canvas can be easily removed by simply pushing up the presser piece of the presser metal fitting with your fingers and returning it to its original state. Furthermore, the presser metal fitting can also be removed immediately by, for example, rotating it to release the engagement with the protruding edge.

In this way, by using a presser metal fitting that can be attached to and detached from the frame bone with one touch without requiring screw hole processing in the frame bone, the operation of attaching and detaching the campus is extremely easy with one touch.

In addition, the pair of projecting edges of the frame bone can be used in combination with both sides of the groove for inserting the frame bone connecting metal fitting formed on the conventional frame bone, and there is no need to newly form them on the frame bone. be.
