As described above, within the case 2, the operating arm 4, the intermediate arm 5, and the connecting arm 7 are connected to different moving axes 41, 51, .
71, and the operating arm 4 and the operating arm 6 are connected by press-fitting with an appropriate frictional force, and the six arms are connected in the above-mentioned combination, so that the operating arm 4 can be attached to the panel 2. By retracting it to a position where it does not protrude from the end face, the rotation of the six arms is restrained and maintained in the state shown in FIG. 2, and the six arms do not protrude from the end face of the panel 2.

By doing so, it is possible to prevent the six arms from being damaged when the panels 1 and 2 are transported.

On the other hand, when the panels 1 and 2 are connected, with the concave groove 11 and the convex part 21 at the center of the end faces engaged and abutted against each other, a gap of 10°10 is formed on both front and rear sides. The gap 1 is provided at the base of the convex portion 21 and the side wall portion near the opening of the case 22 so that the operating arm 4 can be operated from the

A bar 8 is inserted into the case 22 through the window holes 24 and 25 from one of the gaps 10, 10 formed on both the front and rear sides of the convex portion 210, and the operating arm 4 is inserted into the case 22 with this bar 8. Rotate it in the A direction.

As a result, the operating arm 4 rotates around the first shafts 41, 41, and the operating arm 6 press-fitted to the boss portion 42 of the operating arm 4
is rotated together with the operating arm 4 in the direction of the arrow due to the frictional force between the boss portion 42 and the shaft hole 61, and further, due to the rotation of the operating arm 6, the connecting arm 7 is attached to the fulcrum shaft 7 via the notch 62 and the pin 72.
1 in the direction of the arrow, the distal end locking portion 73 of the connecting arm 7 protrudes from the case 22 and enters the other case 12, and the locked pin in the case 12 3.

At this time, the rotational force of the operating arm 40 is transmitted to the intermediate arm 5 through the cam 43 and the elongated hole 52, and the intermediate arm 5 rotates around the second shaft 51 in conjunction with the rotation of the operating arm 4. Fulcrum shaft 7
1 also rotates around the second shaft 51, but the operating pin 72
The distance from the center of rotation of the operating arm 60 (i.e., the center of the first shaft 41) for rotating this around the fulcrum shaft 71 to the center of rotation of the intermediate arm 50 (i.e., the center of the second shaft 51)
The distance is greater than the distance from the center of rotation of the cam 430 for rotating the intermediate arm 5 (i.e., the center of the first shaft 41), and from the fulcrum shaft 71 of the connecting arm 7 to the locking portion 73 at the point of action. distance from the fulcrum shaft 71 to the operating pin 7 at the point of effort.
2, the distal end locking portion 73 can be reliably engaged with the locked pin 3 without interfering with the rotation of the connecting arm 70, and the rotation of the operating arm 4 can be prevented. can be transmitted to the connecting arm 7 at increased speed, and the connecting arm 7 can be quickly engaged with the locked pin 3 just by slightly rotating the operating arm 4.

When the distal end locking portion 73 of the connecting arm 7 engages with the locked pin 3 in this manner, the rotation of the connecting arm I is prevented, and accordingly, the rotation of the operating arm 60 is also stopped.

After that, when the operating arm 4 is further forcibly rotated against the friction between the boss part 42 and the shaft hole 61, the operating arm 40 rotates while slipping between the boss part 42 and the shaft hole 61. cam 4
3 and to the intermediate arm 5 through the elongated hole 52, the intermediate arm 5 rotates around the second shaft 51, and the fulcrum axis T1 of the connecting arm T moves in the direction of the arrow. A tensile force acts on the stop pin 3 in the two directions of the arrows, and this tensile force causes both panels 1 to
The end faces of 2 are forcibly brought into close contact with each other (crimped) and tightened to connect.

Just by rotating the operating arm 4 in the direction of arrow A in this way,
Rotate the connecting arm T in the direction of the arrow to lock the end locking portion 73
is engaged with the pin 3, and then the connecting arm 7 is moved in the two directions of the arrows, the pin 3 is pulled toward the panel 2 side, and both panels 1
, 2 can be connected by pressing the concave grooves 11 and protrusions 21 together, the operation for connection is extremely simple, and by using a lever and cam mechanism, the panels 1 and 2 can be quickly and easily connected. It can be firmly connected and greatly improves work efficiency.

Nao, when connecting the panels 1 and 2 above, the operating arm 4 can be easily operated by inserting the bar 8 through the gap 10 and the window holes 24 and 25 created at the butting part of the panels 1 and 2, so There is no need to provide a hole for operation, and the gap 10 etc. can be easily hidden with a sealing material 26 such as rubber banking after the panels are connected, so it can be used in a very stylish manner.

Further, after the connection, the operating arm 4 and the operating arm 6 are prevented from rotating due to the frictional force between the i-4 boss portion 42 and the shaft hole 61, and therefore, the distal end locking portion 73 of the connecting arm 7 and the pin 3 are engaged with each other. , there is no risk of the tightening loosening unexpectedly, and the connected posture can be firmly maintained.

When separating the panels 1 and 2 after connection, the sealing material 26 inserted into the gap 10 is removed and the window hole 24 is removed.
, 25 into the lower side of the operating arm 4, the bar 8 pushes up the operating arm 4, and the operating arm 4 is moved against the friction between the boss portion 42 and the shaft hole 61 in the opposite direction to the connection. By rotating the actuating arm 6, the connecting arm 1, and the intermediate arm 5 in the opposite direction to the direction in which they were connected, the distal end locking portion 73 of the connecting arm 7 is disengaged from the pin 3, and the panels 1 and 2 are rotated. Can be unlinked.

By the way, the present invention is not limited to the above-mentioned embodiment, but can also be implemented as follows.

The panels 1 and 2 are not limited to being made of foamed resin, and may be made of wood such as veneer plywood or particle board, or steel plate.

Further, depending on the structure of the panel, the cases 12 and 22 may be omitted.

The pin 3 and each arm are not limited to being installed inside the panels 1 and 2, but may be provided on either or both of the front and back surfaces of the panels 1 and 20.

In the illustrated example, the operating arm 4 and the connecting arm 7 are rotated in the same direction, but they may be rotated in opposite directions.

The panel connecting device of the present invention can be used not only when the panels 1 and 2 are arranged on the same plane and connected, but also when the panels 1 and 2 are connected in an L-shape, T-shape, or any other desired angle so that they intersect.

In addition, the shape and arrangement of the six arms and the specific structure of each connecting portion are not limited to the illustrated example, and may be modified as appropriate without departing from the gist of the present invention.

As explained above, according to the present invention, it is possible to hold the six arms so that they do not protrude from the end surface of the panel in the unconnected state,
It is possible to prevent damage to the six arms when transporting the panel, and when connecting the panels, the locking part (pin) at the end of the connecting arm can be rotated with an extremely simple operation of rotating the operating arm. The two-step action of engaging the panel and tightening the locked part by pulling the fulcrum shaft of the connecting arm together makes it possible to easily and firmly connect the panels together. The six arms are kept in a stopped state by the friction between the press-fitted parts of the operating arm and the actuating arm and the rotating parts of the six arms, and the above-mentioned connections do not come loose unexpectedly, making it possible to firmly maintain the connected state, which is highly practical. There is a certain effect.
