Hereinafter, a usage state such as assembling of the frame member 1 and the corner connecting member 5 configured by the above-described elements, mounting of the posted object 3, and rotation of the frame member 1 will be described.

To assemble the frame, the side surface 51 of the corner connecting member 5 and the upper rotation stopping portion 53 to the lower rotation locking portion 52 are pushed into the end portion of the second space A of the frame member 1 and inserted. , Pivotally connected.

The flange 15 is pressed against the side surface 51, and the side surface 51 is housed in the second space A of the frame member 1 while being elastically deformed.

The shaft portion 51a of the side surface 51 is in sliding contact with the concave bearing portion 15a of the frame member 1 and serves as a pivot point of the frame member 1.

The convex engaging portion 17 of the frame member 1 and the concave connecting portion 55 of the corner connecting member 5
Is fitted at the same time as the pivotal connection, so that the movement locking in the pivotal axis direction is completed.

When the operation of pushing the side portions 51 of the four corner connecting members 5 into the second space A of the four frame members 1 is repeated four times, the frame of the frame having the rotating frame members 1 shown in FIG. Assembly is complete.

As shown in FIG. 9 or FIG. 11, the posted object is mounted by pivoting the frame member 1 outward with the shaft portion 51a of the corner connecting member 5 as the center and opening the frame member 1 in an arc shape. Place the object 3 on the partition 11 and rotate the shaft 51a in the opposite direction to move the first part.
0 Close as shown.

The arc-shaped partition 11 of the frame member 1 rotates while slidingly contacting the rear peripheral portion of the object 3 to be posted in the first space B between the engaging portion 12 on the front surface of the frame member 1. Object 3 will be clamped.

The rotation of the frame member 1 is increased, and as shown in FIG.
By tilting 12 below the upper surface of the partition 11, the object 3 can be pulled out from the side of the frame.

If the frame members 1 on two adjacent sides are opened as shown in FIG. 8, the object 3 can be attached and detached from the upper surface.

The rotation stop of the frame member 1 is performed by the rotation stop portions 52, 53, 54 formed by providing a step and a concave portion on the sliding contact surface of the corner connecting member 5 which is in sliding contact with the rotation locking portion 13 of the frame member 1. .

Depending on the depth of the recess, the height of the step, and the strength of the side portion 51, it is set for temporary stop and stop.

An inclined surface 52a provided above the rotation stopping portion 52 shown in FIG.
Serves to feed the locking claw 13 of the frame member 1 into the rotation stopping portion 52.

The locking portion 13 of the frame member 1 is engaged with the stop portion 52 by the inclined surface 52a, so that the frame member 1 can be prevented from being opened accidentally.

If the angle of the inclined surface 52a is within 90 degrees with respect to the rotation stop surface 52 and the inclined surface 52a is an inclined surface projecting to the inside of the frame, it can be fixed with a strong force.

When the end of the frame member 1 is cut at 45 degrees and the frame member 1 is abutted at a right angle, it is impossible to close the frame body by colliding with the end face of the adjacent frame member 1. There is.

For this reason, as shown in FIGS. 2 and 3, the inclined surface 152a is provided at the tip of the tongue-shaped spring 152 provided on the rotary sliding contact surfaces 54a and 54b, and the tongue-shaped spring 152 is provided at the corner connecting member 5. The frame member 1 is closed by pressing inward. The strength of locking can be freely adjusted by the material, the shape of the tongue-shaped spring 152, and the angle of the inclined surface 152a.

The tip of the tongue-shaped spring 152 may not be the inclined surface 152a but may be a locking stepped portion 152d as shown in FIG.

In this case, if the locking step portion 152d and the inclined surface 152a are used together, and the locking step portion 152d of the tongue-shaped spring 152 can be folded at the portion of the groove 152e, the frame for the folded tongue-shaped spring 152 can be obtained. The member 1 serves as a rotatable frame member, and the frame member 1 in which the locking step portion 152d of the tongue-shaped spring 152 remains unchanged does not rotate.
Becomes In this way, the frame member that rotates with the same corner connecting member 5 and the frame member that does not rotate can be arbitrarily selected.

152f is a claw for releasing the fixation of the locking step portion 152d or a finger hook. Instead of the locking step portion 152d provided on the tongue-shaped spring 152 of the present embodiment, another member is assembled and the rotation locking portion 13 is provided. It is also possible to arbitrarily switch between locking and locking and locking.

Improving the closeness of contact between the corners of the forehead, and assembling the frame member 1 whose end surface is cut at 45 degrees with the corner connecting member 5 so that the cut surfaces of the frame member 1 abut against each other When pivoted to the outside, the parts entering the inside of the pivot axis collide with each other and do not move. Therefore, the notch 18 shown in FIG. 7 must be provided at this collision part.

However, when the forehead is viewed as a product, the cutout portion 18 becomes a serious defect such as a hole in the corner of the forehead.

The closeness of contact between the corners of the forehead requires precision, which is called the life of the forehead.

Further, if the opening angle of the tip portion of the side surface 51 is increased together with the feeding effect of the inclined surface 152a so that the side surface 51 is repelled to the outside as shown in FIGS. 5 and 6, the side portion 51 causes the frame member 1 to move. The concave bearing portion 15a is pushed outward and can act as a force for closely contacting the corners.

Note that the repelling force of the side surface 51 acts to repel the concave bearing portion 15a of the frame member 1 to the outside, as shown in phantom lines in FIGS.

Since the concave bearing portion 15a is moved outward by the force of the side surface 51,
The collision portion of the end surface of the frame member 1 due to the rotation of the frame member 1 is reduced by the amount of movement to the outside, so that the cutout portion 18 can also be reduced in size.

Further, in order to make the cutout portion 18 smaller, it is preferable to make the tip portion of the side surface 51 thinner and the shaft portion 51a smaller as shown in FIG.

Alternatively, if a metal leaf spring of about 0.4 to 0.5 mm is assembled, it can be made smaller.

Further, if the slidable side surface of the convex locking portion 17 of the frame member 1 and the concave connecting portion 55 of the corner connecting member 5 is formed into an inclined surface, the corner connecting member 5 is moved by the rotating action of closing the frame member 1. The frame member 1 can be moved in the direction of the pivot axis.

Further, by rotating the frame member 1 so as to open, the corner connecting member 5 can be sent out in the pivot axis direction.

As a result, it is possible to move to the outside of the frame along the axis of the pivot axis.

It is more effective to provide a step 19 projecting upward in the notch 18 as shown in FIG. 7 so that the notch 18 is difficult to see from the front of the forehead.

When the thickness of the post 3 is smaller than the predetermined one, a gap is generated between the front engaging portion 12 of the frame member 1 shown in FIG. 9 and the post 3, the transparent plate 4 and the like.

In order to prevent this, the leaf spring 61 or 61 shown in FIGS.
As a is installed between the middle partition 11 and the frame front engaging portion 12, and the frame member 1 is closed from the state in which the body 3 is placed on the middle partition 11, the leaf spring 61 causes the body 3 to post. Is pushed up from the rear surface and pressed against the front engaging portion 12 of the frame member 1 to prevent a gap.

Depending on whether the connecting portion between the frame member 1 and the corner engaging member 5 is detachable or remains fixed, the convex locking portion 17 and the concave connecting portion 55 of the frame member 1 and the corner connecting member 5 are connected. Determine the shape and location of attachment.

In the case of the detachable type, the left and right frame members 1 of the frame member 1 to be removed are rotated to a predetermined angle and opened, and the central frame member 1 is pushed up to release the convex locking portion 17 and the concave connecting portion 55. To do.

The predetermined angle is determined by the usability, such as the position where the frame member 1 is fully opened, or during the rotation.

It should be noted that it is preferable to combine a means such as providing a temporary engaging rotation engaging portion 54 in the middle of the rotation so as to detect each position.

The connection of the frame members can also be released by the following method.

The lower end of the side surface 51, which is the shaft portion 51a, is partially cut away to form a partially cut-out portion 51p shown in FIGS. 2 and 3, and the tip of the screw driver is applied to this, and the flange 15 of the frame member 1 is attached. When a force is applied with the edge as a fulcrum, the side surface 51 is elastically deformed and comes off the flange 15.

Both ends of the frame member 1 are cut at 45 degrees, and one end of each frame member 1 is directly fixed to both ends of one frame member 1,
The corner connecting member 5 shown in FIG. 2 is connected to the other ends thereof.

Then, when the frame member 1 remaining on the corner connecting member 5 is fitted and connected, a frame which rotates only one side of the frame is obtained.

In this case, the object 3 is pulled out from the side surface.

As shown in FIG. 5, if the lower end portion 58 of the corner connecting member 5 is projected as compared with the position of the lower end portion 1a of the frame member 1, the frame member 1
Since the lower end portion 1a of the above can be rotated without coming into contact with the wall surface, the posted object 3 can be exchanged while the frame is locked to the wall surface or the like.

The embodiment shown in FIG. 17 shows an embodiment different from the connecting structure of the convex engaging portion 17 and the concave connecting portion 55 of the frame member 1 and the corner connecting member 5 shown in FIG. 1 and FIG. Is.

Connection locking slope 117a of the hole 117 provided in the partition 11 of the frame member 1
And the connection locking projection 155 provided on the corner connection member 5 are in sliding contact with each other and relatively move.

Due to the connection locking inclined surface 117a, the corner connecting member 5 is pulled into the frame member 1 or the pulling force is released by the rotation of the frame member 1.

Alternatively, the corner connecting member 5 can be forcibly sent out from the inside of the frame 1 by providing the guide 117f like an imaginary line.

Reference numeral 352a represents an inclined surface that bends over into the corner connecting portion 5 provided in the spring body formed from the rotation stop portion 52 and the corner-tree reinforcing plate 50 side.

The embodiment shown in FIGS. 18 to 20 shows an embodiment in which the frame member 1 is cut at a right angle.

In the corner connecting member of this embodiment, one of the orthogonal connecting parts is used as a rotating connecting part, and the other is used as a non-rotating connecting part in a pair of left and right, and the posted object 3 of the rotating frame member 1 and the like. A cap 121 is attached to both ends of the front engaging portion 12 to form a lid.

One side surface 251 of the corner connecting member in this figure functions as a spring body when fitted and locked inside the flange 215 of the frame member 1Q that does not rotate.

The hole 217 provided in the partition of the frame member 1Q is the side surface 251 of the corner connecting member.
It serves as a connecting and locking portion that fits with the protrusion 255 provided above.

If the frame member 1 is cut at a right angle as in this embodiment, it is possible to prevent the corners of the frame from having a sharp shape.

Furthermore, since the cap 121 is attached to the end of the rotating frame member 1, it is possible to eliminate a more acute feeling.

In the embodiment shown in FIG. 21, the shape of the frame member 1 is flat and thin.
