BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel or display panel connecting device in which a plurality of rectangular frames are bent and connected at a predetermined angle, and decorative plates are attached to both front and rear surfaces of each frame.

[0002]

2. Description of the Related Art Conventionally, in order to connect the above-described panels by bending them at a predetermined angle, the vertical frame rods of each frame are connected by bolts and nuts through connecting fittings that bend at a predetermined angle. However, it is troublesome to use a tool to tighten the bolts.

A device that solves this problem is the actual machine 64-148.
As described in Japanese Patent Publication No. 14, the apparatus has a drawback in that the shape and structure of the members are complicated, it cannot be manufactured more easily than a steel plate, and it becomes expensive.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device for simply and firmly connecting both frames at a predetermined angle by using an inexpensive press-molded member without using bolts or nuts. It is what

[0005]

In order to solve the above-mentioned problems, according to the present invention, a plurality of rectangular frame members are connected to each other and a decorative panel is attached to the front and rear surfaces of each frame member. The laterally elongated insertion holes formed in a plurality of important points on the inner and outer both side surfaces of the left and right vertical frame rods, and the insertion holes that project laterally at a predetermined angle from each other at the peripheral edge of the horizontal substrate. By connecting a plurality of connecting arms that can pass through, on both sides of the base end of each connecting arm in the board, a stopper that is larger than the lateral width of the insertion hole is formed, and by the constricted portion provided near the free end of each connecting arm, It consists of a connecting plate with a locking part formed at its free end, and a tightening handle that is bent in a U-shaped groove and has notch engaging grooves near the tips of both side plates protruding in the length direction. Insert the connecting arms into both insertion holes that make the height of the vertical frame rod of each frame body, and put each stopper on the outside of the vertical frame rod. The engaging groove of the tightening handle with the engaging portion of each connecting arm projecting from the inner side surface, and rotating each tightening handle around the engaging portion. The frame rod is tightly held between the stopper of each connecting plate and each tightening handle.

[0006]

[Operation] The engaging groove of each tightening handle is engaged with the engaging portion of each connecting arm that is inserted into each through hole that forms the same height of both vertical frame rods of both frame bodies to rotate the tightening handle. When it is moved, its tip is pressed against both ends of the insertion hole on the inner surface of the vertical frame rod, and each vertical frame rod is tightly held between each stopper of the connecting plate and each tightening handle, and both frame bodies are connected to each other. It is firmly connected in the same direction as the arm.

If a U-shaped groove is formed on the inner surface of the vertical frame rod and each tightening handle connecting both frame bodies is housed, there is no obstruction when attaching the decorative plate to each frame body. Since the tightening handle does not come into contact with the free end of the tightening object and is not caused to swing or shake to the side, the two frame bodies are connected more safely and securely.

If the fitting of the connecting plate is provided on the base plate and the connecting portions of both panels are covered, the appearance of the connecting panel is significantly improved.

The second cover is attached to the mounting portion (18b) of each of the second locking metal fittings (18).
Engage each locking hole (not shown) of (22) to attach the second cover (22).
Attach.

Then, the other connecting arm (1) of each connecting plate (8)
(0) is a vertical frame rod of the frame body (2) which is oriented in a direction perpendicular to the frame body (2).
If (4) is attached in the same manner as described above, both frame bodies (2) and (2) are firmly connected.

Next, the decorative plates (3) and (3) are attached to both front and rear surfaces of both frame members (2) and (2), and the mounting portions (1) of the first locking metal fittings (17) of the connecting plates (8) ( 17b), the locking hole of the first cover (20)
If (21) is locked and the first cover (20) is attached,
And a connecting panel bent at a right angle is obtained as shown in FIG.

Since the tightening handle (14) used to connect the two frame bodies (2) and (2) is recessed in the U-shaped groove (6), the decorative plates (3) and (3) are formed on both front and rear surfaces. Since it does not get in the way when attaching, and there is no danger that the tightening handle (14) will rotate upward or swing to the side due to other objects touching its free end,
(2) The connection of (2) is safe and reliable.

The assembled connecting panel can be easily disassembled by the reverse operation of the above. In the above description, the engaging grooves (15) and (15) of the tightening handle (14) are connected to the connecting plate.
Both ends of the locking portion (13) of (8) were engaged from below, but the tightening handle (14) was turned upside down and engaged from above to move the tightening handle (14) upward. It may be rotated.

FIG. 9 shows a second embodiment of the present invention. The same members as those in the previous embodiment are designated by the same reference numerals and the description thereof will be omitted.

A connecting plate (3) corresponding to the connecting plate (8) of the previous embodiment.
At the periphery of the substrate (32) of 1), three connecting arms (10), (10), (10) that are oriented in three directions in a T shape are continuously provided, and the essential points of the substrate (32) are

[Effect of device]

(a) Panel connection does not require the troublesome bolt tightening work using a tool, it can be quickly performed with a simple handle operation, and disassembly can be done easily as well. The effect is particularly great for the connection panel to be made. (b) Since the vertical frame rods are tightened at a plurality of positions by the lever principle through the connecting plates, both panels are firmly connected. (c) Since all the members used for connecting the panels can be manufactured only by pressing the steel plates, they can be mass-produced at low cost. (d) If a U-shaped groove into which the tightening handle can be inserted is formed on the inner surface of each vertical frame rod, the tightening handle will be recessed in the U-shaped groove when both frames are connected. It does not get in the way of attaching the decorative plates on both sides, and the tightening handle has a safe connection between the two frames because there is no risk of other things touching the free end of the tightening handle and causing it to swing to the side. And certain. (e) If the locking plate is provided on the base plate of the connecting plate and the connecting parts of both panels are covered, the appearance of the connecting panel is significantly improved.
