2. Description of the Related Art As a frame for holding a poster of this kind, the one described in Japanese Utility Model Publication No. 3-17742 can be cited as an example, and the poster is provided by a pair of frames pivotally supported so as to be openable and closable with respect to each other. Although it is hung by sandwiching it like a hanging curtain or a banner, in the conventional case, as shown in the publication, the shaft fulcrum is at the center of the width and the end of the mouth and the opposite side. There was a limit to the opening angle of the mouth due to the structure in which the opening and closing alternate.

Further, in order to obtain the opening action, an elastic material is interposed on the opposite side, which requires a lot of labor to attach and detach, which is inconvenient to handle, and a strong elastic material cannot be used. , The bulletin board could not be held stably.

Regarding the stability to stop the posted matter,
In Japanese Utility Model Laid-Open No. 5-95362, there is a proposal to use a magnet or an insertion pin. However, even if the object is sandwiched by the attractive force of the magnet, the object is thick or has unevenness. Is unable to fully exert the force of the magnet,
In addition, the attachment pin was unstable in mounting and was easily dropped off.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention provides a frame for holding a posted matter which is easy to attach / detach and which can be firmly and stably fastened. Aimed to provide.

[0006]

In order to achieve the above-mentioned object, the present invention has an outer peripheral wall formed in a curved channel shape.
It consists of a pair of base frame and counter frame
And the opposite frame to the base frame on one side
By forming a shaft pocket that fits into it on the other
Connect at the upper end so that it opens and closes at a certain angle, and
End of the post with both opening and closing pieces of the door and the opposite frame
Energize both opening and closing so that parts can be sandwiched
A U-shaped pin is inserted between the two frames to attach it to the base frame.
Is a tentative line that passes diagonally from the center of the axis through the opposing frame.
The line goes through the wide retaining groove through the inner wall on the line of thought.
Formed by opening in the direction of the counter frame by opening and closing
A hooking groove protruding up and down over the virtual line is projected from the inner peripheral surface.
The U-shaped pin on one side to the wide catch groove and on the other side to the catch groove.
The present invention provides a frame for holding a posted object, which is configured so that the U-shaped pin is hooked in the hooking groove of the counter frame and is turned upside down over a dead point.

Since the frame for holding the posted object is constructed as described above, the place where the U-shaped pin hangs in the locking groove of the base frame is used as the swinging fulcrum of the U-shaped pin, and it is located from the center of the opening / closing shaft. It has a dead point on the line passing through the fulcrum point. Therefore, when opening the bulletin board for insertion, if the portion where the U-shaped pin hangs in the hooking groove of the counter frame exceeds the dead point, the elastic force acts in the opening direction and the open state of a certain angle is maintained. Retained. Further, in this case, since the U-shaped pin moves in the width direction on the side of the wide locking groove, it is possible to set a large reversal angle of the U-shaped pin (both are narrow locking grooves. This will allow the opening angle of the counter frame to be large.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the strong U-shaped pin 3 can be used for the force of pinching the sign P, but the holding force is further increased by interposing a large number of U-shaped pins. Can be increased.

The cross-sectional shapes of the base frame 1 and the counter frame 2 are not particularly limited, but if the mouth pieces 11 and 12 have a recess, it is easy to put a hand on and to open and close the work easily. .

It is desirable to take some kind of fastening means such as a shape in which protrusions and recesses are engaged with each other so that the mouth portion for sandwiching the bulletin board does not come off.
When the ridge 23 is pressed against the cushion material 7,
A strong and stable fastening state can be obtained. When attaching the insert pin 5, the head 6 of the insert pin 5 is protruded to the ridges 15, 16, 1
When you apply it for 7 minutes, you will never lose your stability.

[0011]

As described above, according to the frame for holding a sign of the present invention, not only can the counter frame be opened greatly with respect to the base frame, but also the open / closed state can be held by the strength of the spring. Therefore, there is an excellent effect that replacement work for attaching and detaching the posted matter is facilitated, a strong fastening force is obtained, and the posted matter can be stably supported.

[0012]

Embodiments of the present invention will now be described with reference to the drawings.

The drawing shows an embodiment, a picture of which,
A frame F for holding a material such as a poster is composed of a base frame 1 and a counter frame 2 that is pivotally supported so as to be openable and closable with respect to the base frame 1, and a U-shape as a spring that urges in both directions in the meantime. The pin 3 is interposed, and the base frame 1 is equipped with an insert pin 5 with a head 6 for piercing the post P and a cushion material 7 for preventing the post P from slipping.

The base frame 1 and the counter frame 2 are
It has a substantially symmetrical outer shape, and is openably and closably connected by a shaft pocket 9 and a shaft 10 fitted therein at the upper end,
At the lower end, mouth pieces 11 and 12 for sandwiching the posted matter P are formed in a concave shape and slightly curved so that it is easy to hold.

The base frame 1 has a hanging piece 8 projecting from the upper end so as to be the main body of suspension. The internal structure of the base frame 1 is from the middle part of the outer peripheral wall to the lateral wall 13 and the axial pocket 9.
The slant walls 18 are respectively projected from the above, and the wide retaining groove 14 is formed in the projecting portion in an oblique opening in which the slant wall 18 faces. In addition, the mouth piece 11 and the lateral wall 13 are provided with three ridges 1 near the rim of the mouth.
5, 16 and 17 are provided so as to face each other, and the first upper and lower ridges 1
Steps 5 and 15 are provided with steps at the rims, and the cushion material 7 is fitted between the steps.

Further, the protrusions 15, 16 and 17 are arranged in parallel with each other so as to sandwich the head 6 of the thumbtack serving as the insert pin 5, and by hooking between them, the mouth piece 11 and the lateral wall 13 are formed.
The head 6 is held between and. In this case, although it is inserted between the ridges 15 and 16 close to the rim, it can be inserted between the distant ridges 16 and 17 to adjust the protruding length of the insertion pin 5. Further, the base frame 1 is provided with screw pockets 19, 19 at both ends of the lateral wall 13, and screws 21, 21, 21, 21 for fixing the end face cover 20 are screwed into the screw pockets 19, 19.

The counter frame 2 has a shaft 10 as a center of opening and closing at an upper end thereof and a ridge 23 of a closing port at a lower end thereof, which projects from the shaft 10. As shown in FIG. When the lip 25 serves as a stopper and supports it, the opening angle of the facing frame 2 becomes maximum. Also,
The counter frame 2 has a hooking groove 27 for the U-shaped pin 3 on the inner peripheral surface.
Is projected, and the position of the shaft pocket 9
When an imaginary line R passing from the center to the center of the wide groove 14 is hypothesized, the imaginary line R is flipped up and down substantially equally at the imaginary line R as a boundary.

FIG. 1 shows a state in which the article P is used as a banner by sandwiching the upper and lower ends of the post P with holding frames F, F respectively. The holding frame F is hung and the lower frame is used. F is a weight. In each case, as shown in FIG. 2, the post P is pressed against the cushion material 7 by the ridge 23 and is sandwiched, and the insertion pin 5 pierces, so that the post P is never removed.

The elastic state of the U-shaped pin 3 holds the closed state (FIG. 2) at this time and the opened state (FIG. 3) when the post P is replaced. Since the position where the U-shaped pin 3 engages with the retaining groove 14 moves within the wide range, the dead point positions Sa, S
b has changed, but in any case, the U
Looking at the portion on which the character pin 3 hangs, it is below the dead point position Sa in the closed state and above the dead point position Sb in the open state, so it is U-shaped in both the closed and open directions. As a result of the elasticity of the pin 3, both the open and closed positions are stably held.

In the above example of use (FIG. 1), the holding frames F, F are used in the upper and lower two, but it is also possible to use one upper end, or four upper, lower, left and right via the corner connector. It can also be used as a framework. In this case, the legs of the connecting tool are hung between the ridges 15, 16 and 17 of the base frame 1 and fitted between the lateral wall 13 and the mouth piece 11.
