DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given with reference to FIGS. The holding member A for a frame includes a mounting portion A1 to be mounted in the mounting groove B1 of the hollow frame B, and a pressing portion A for pressing a back plate B3 of the frame.
It consists of 2 and.

The mounting portion A1 has a connecting portion A4 having a substantially circular cross section on the upper surface of a substantially central portion of a mounting base portion A3 fitted into the mounting groove B1 of the hollow picture frame B. The mounting base A3 is made rotatable. When the mounting portion A1 is formed by swelling a spherical portion A5 at a symmetrical portion on the upper surface of the mounting base portion A3, specifically, at the symmetrical portion at the base of the connecting portion A4, and rotating the mounting base portion A3 around the connecting portion A4. The spherical portion A5 engaged with the engaging portion B2 of the mounting groove B1 of the hollow frame B is configured to be able to rotate smoothly with low frictional resistance. The mounting portion A1 is provided at a symmetrical portion on the upper surface of the mounting base A3 at the base of the connecting portion A4 in a direction intersecting an imaginary line connecting the spherical portion A5 (specifically, a direction intersecting at right angles). An attachment base A3, which is provided with a locking protrusion A6 for locking, and which is turned around a connecting portion A4.
Is fixed so that it does not move, and also prevents rattling.

The mounting portion A1 has a convex arcuate surface A9 (round bracket A) on the side of the mounting base A3 on the side where the resilient holding rod protrudes.
9), so that rotation around the connecting portion A4 can be smoothly performed. The mounting part A1 is connected to the connecting part A4.
A vertical ridge A10 parallel to the center line (axial center) of the connecting portion itself is projected from the side surface on the side where the elastic holding rod protrudes, and a locking portion is provided between the opposing surfaces of the locking portion B2 of the mounting groove B1. B2 is pressed against one side surface, and the mounting base A3 is fixed so as not to move and without rattling.

The holding portion A2 is held at an end (an upper end of the connecting portion A4 in FIG. 1 and FIG. 2) opposite to an end of the mounting base (the lower end of the connecting portion A4 in FIGS. 1 and 2). Base A7
And the pressing base is exposed on the locking portion B2 of the mounting groove B1. The holding part A2 is provided with a holding base A7.
One end of this is extended slightly thinly to project a resilient holding rod A8,
The back plate B3 is configured to be elastically pressed by the tip of the holding rod.

[0008] The frame holding device A having the above-described structure includes a connecting portion A4.
A mounting base A3 is formed at one end (lower end in FIGS. 1 and 2), a pressing base A7 is formed at the other end (upper end in FIG. 1), and a connecting portion A4 is engaged with the mounting groove B1. The mounting base A3 and the spherical portion A5 and the locking projection A6 formed thereon are fitted in the mounting groove B1 so as to penetrate between the opposing surfaces of the portion B2, and the pressing base A7 is elastically pressed by the pressing base A7. Are protruded. Accordingly, when the mounting base A3 in the mounting groove B1 is rotated about the connecting portion A4 as described above, the spherical portion A5, the locking projection A6, the resilient pressing rod A8, and the like are simultaneously rotated.

As a result, as shown in FIG. 5, in a state in which the elastic pressing rod A8 elastically presses the back plate B3,
By lifting the pusher bar A8 and turning it in the direction of the arrow,
As shown in FIG. 6 and FIG. 7, it is possible to displace the elastic pressing rod A8 onto the locking portion B2 of the mounting groove B1 (displacement by 90 °), and in the state shown in FIG. 6 and FIG. The board B3, the colored paper F, etc. can be taken out of the frame, so that the frame presser A does not have to be detached from the frame B each time, and the product can be made easy to use. Further, the side surface of the mounting base A3 of the mounting portion A1 on the projecting side of the elastic pressing rod is a convex arc surface A9 (circle bracket A
9), the rotation about the connecting portion A4 can be smoothly performed.

[0010] By projecting a vertical ridge A10 parallel to the center of the connecting portion on the side of the connecting portion A4 on which the elastic holding rod protrudes, the connecting portion A4 is connected between the opposing surfaces of the locking portion B2 of the mounting groove B1. Part A
4, the vertical ridge A10 also penetrates the same, and the ridge is disposed on the same side as the resilient presser rod A8. While elastically pressing, the vertical ridge A10 is pressed against one side edge of the locking portion B2 to maintain the back plate pressing state of the elastic pressing rod A8, and at the same time, the mounting base A3 is loose. Secure it so that it does not move. In the state shown in FIG. 5 where the elastic pressing rod A8 elastically presses the back plate B3, the spherical portion A5 is caused by an upward force acting on the pressing base A7.
It presses against the lower surface of the locking portion B2, and in combination with the vertical ridge A10, stably maintains the back plate pressing state of the elastic pressing rod A8.
