This prevents it from coming off and bending toward the back surface, and at the same time prevents it from bending inward.

[Problem that the invention attempts to solve]

The above configuration is sufficiently useful for relatively small picture frames, and since there are few engagement points, the manner of engagement at each engagement point may be different as shown in FIGS. 12 and 13. However, it is not a particular problem. However, as larger picture frames have more engagement points, it is inconvenient to work if the engagement mode differs from one engagement point to another, and the problem is that the presser frame is easily distorted due to the difference in engagement structure. be.

Further, the engagement mode shown in FIG. 12 cannot prevent the presser frame 23 from being bent inward, and the case shown in FIG. 13 has the problem that it cannot prevent the presser frame 23 from bending toward the front side.

This invention aims to solve the above-mentioned problems by making the engagement structures of each engagement part the same structure.

[Means for solving problems]

In order to solve the above problems, this invention fits a presser frame 2 on the inner periphery of the frame body 1, and holds an ornamental object 3 such as a painting fitted in the frame body 1 between the presser frame 2 and the back plate 4. In a picture frame that can be held between the frames, an inner wall 5 protruding toward the back side is provided inside the frame 1, and a receiving tsuba 6 is provided on the edge of the inner wall 5 and protruding inward. An engaging recess 7 is provided which is open to the engaging recess 7, and the inner width a of the engaging recess 7 is smaller than the outer width b and larger than the dimension d between the inner ends, The dimension c is larger than the width a, and the dimension d is smaller than the width a, and the engagement claw 12 is provided protrudingly on the outside of the engagement protrusion 11. The engaging claw 12 is formed to be smaller, and the engaging claw 12 is engaged with the rear end surface of the pressing piece 9, and the engaging protrusion 11 is engaged with the engaging recess 7.

[Effect]

Insert the presser frame 2 into the inside of the frame 1 from the surface side, apply the engaging claw 12 to the pressing piece 9, and press the pressing piece 9.
Slightly bend outward to move the engagement protrusion 11 into the engagement recess 7
from the front side of the pressing piece 9, and engage the engaging claw 12 with the edge of the back side of the pressing piece 9.

The presser frame 2 has an outer wall 10 that is connected to the receiving collar 6 of the frame body 1.
This prevents it from slipping out to the back side and from bending. Furthermore, the engagement between the engaging claw 12 and the presser piece 9 prevents it from coming off toward the surface and from bending. Furthermore, the engagement between the engagement protrusion 11 and the engagement recess 7 prevents the presser frame 2 from deflecting inward.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

1 to 4 show a frame 1, which is the basic component of the picture frame according to this invention, and a presser frame 2 fitted inside the frame.

The frame body 1 is provided with an inner wall 5 that projects toward the back side, and a receiving collar 6 that projects inward at the edge of the inner wall 5. The presser frame 2 is fitted along the inside of the frame body 1, and as shown in FIG. 3 or FIG.
0 and an inner wall 15, forming a chevron-shaped cross section.

As shown in FIG. 5, the frame body 1 and the presser frame 2 are arranged such that a decorative sheet 16 is pasted on the surface of the frame body 1 and the surface of its inner wall 5, and a decorative sheet 16 is attached between the back plate 17 and the presser frame 2. Insert the ornamental body 3 such as the glass 18 and the decorative frame 1.
It is used by fitting 9.

The engagement structure between the frame body 1 and the presser frame 2 described above is as follows. This engagement structure is shown in Figures 6 to 9.
This will be explained based on the diagram. Please note that these drawings show the state seen from the back of the frame for convenience of understanding.

An engagement recess 7 is formed in the receiving flange 6 of the frame 1. This engagement recess 7 has a so-called dovetail shape in plan view, as shown in FIG. 7A, and the width a on the inner side thereof is smaller than the width b on the outer side. In addition, cuts 8 are formed in the inner walls 5 at both ends of the engagement recess 7.
is inserted to form a pressing piece 9 separated from the inner wall 5.

On the other hand, an engaging protrusion 1 is provided on the outer wall 10 of the presser frame 2.
1 is provided protruding toward the back surface. This engagement protrusion 1
1 has a dovetail shape similar to the engaging recess 7 in plan view, and the dimension c between its outer ends is larger than the dimension d between its inner ends. Also, dimension c
is somewhat larger than the width a, and the dimension d is smaller than the width a. Therefore, if the engagement protrusion 11 were to be inserted into the engagement recess 7 within the same plane, it would collide with both ends of the entrance of the engagement recess 7, and thus would not be able to be inserted.

Furthermore, an engaging claw 12 is provided protruding from the outer surface of the engaging protrusion 11 . The protruding dimension e of this engaging claw 12 is formed to be smaller than the width f of the receiving flange 6.

Next, a method of engagement between the frame body 1 and the presser frame 2 having the above structure will be explained.

As shown in FIGS. 9 and 10, the presser frame 2 is placed against the inner wall 5 of the frame 1 from the front side, and the engaging claws 12 are brought into contact with the pressing pieces 9. In this state, since the protruding dimension e of the engaging claw 12 is smaller than the width f of the receiving collar 6, the engaging protrusion 11 is in the engaging recess 7 in plan view, as shown in FIG. 8A. Although it is within the range, there is no engagement relationship as shown in FIG. Therefore, when the pressing piece 9 is further pushed strongly by the engaging claw 12, it bends inward as shown by the dashed line in the figure.
Therefore, the engaging claw 12 is moved toward the back surface of the frame 1 (first direction).
0), the engaging claw 12 enters the engaging recess 7 and engages with the engaging claw 1.
2 passes over the end surface of the pressing piece 9, the pressing piece 9 returns due to its own elasticity, and the engaging claw 12 rides on the end surface of the pressing piece 9.

When engaged as described above, the engagement between the engagement claw 12 and the pressing piece 9 prevents the presser frame 2 from coming off toward the surface side or from being bent. Also, due to the engagement between the engagement protrusion 11 and the engagement recess 7, the presser frame 2
is prevented from deflecting inward. In addition, presser frame 2
The engagement between the inner wall 5 and the receiving flange 6 prevents the inner wall 5 from coming off or bending toward the rear surface.

Engagement recess 7 and engagement protrusion 1 in the above embodiment
1 have a dovetail shape, but the shape of the engaging recess 7 and the engaging protrusion 11 is not necessarily limited as long as the above-mentioned dimensional relationship is maintained. For example, as shown in FIGS. 10 and 11, a stepped engagement recess 7', a stepped engagement protrusion 1
It may be 1'.

〔effect〕

Since this invention is as described above, it is possible to prevent slippage and deflection in the front-back direction and inward direction by using the same engagement structure.
Therefore, in the case of a large picture frame that requires a large number of engaging parts, the assembly work becomes easier, and there are advantages in that distortion of the presser frame is reduced. Further, lifting of the presser frame can be prevented even in the corner portions without adopting an engagement structure that is particularly different from that in other portions.
