Reference numeral 6 shown in FIG. 2 is a clip that is detachably configured to connect two parallel hinge pins, and is a fifth clip.
The pivotable locking device (hereinafter referred to as a rotation locking member) shown in FIG. 6A was fitted into the center hole 6a _-1 of the hook member 6a shown in FIG. It is a structure.

FIG. 5 (B) is a sectional view taken along line BB of FIG. 5 (A).

_a-2 and 6 _a-3 are the two hinge pins 5 shown in FIG. 1 (C).
It is configured so that it can be engaged with a and 5b.

When the state in which the rotation locking member 6b shown in FIG. 6 (A) is inserted into the center hole 6a _-1 is drawn by an imaginary line, an imaginary line 6b in FIG. 5 (C) is drawn.
As a result, the hinge pins (not shown in this figure) in the recesses 6a _-2 and 6a _-3 are prevented from moving in and out.

The hinge pins of the book are arranged with a space dimension L.

The dimension N shown in FIG. 3 (B) is called a found dimension.

Compared with the case of having one hinge pin as in the conventional example shown in FIG. 12, two hinge pins 5a, 5 as in this embodiment are used.
By arranging b in parallel, the apparent size can be made smaller.

When the found size is reduced, the ratio of the effective area of the panel to the total outline size of the panel is increased, and when the panel is a blackboard, the writable area is increased, so that the practical value is improved.

Reference numeral 6 shown in FIG. 3 (B) is a clip.
FIG. 5B shows the shape shown in FIG. 5C.

The distance between the center points of the _two recesses 6 _a-2 and 6 _a-3 is
As shown in FIG. 3 (B), it is configured so as to be engaged with two hinge pins having a centerline spacing dimension L.

As described above, in the corner member 5 of the present embodiment, two hinge pins are arranged with the center line interval dimension L, and when the two corner members 5 are arranged in close contact with each other, the adjacent corner members 5a and 5b are adjacent to each other. The distance between the hinge pins is L, and the clip 6 is configured so that two hinge pins with the distance L are engaged with each other to connect them.

Further, as shown in FIG. 3 (A), the corner member 5 of the present embodiment has two cylindrical surfaces with a radius L / 2 by rounding the edges in the Y-axis direction (perpendicular to the paper surface). 5h is formed. The cylindrical surface 5h is formed by dividing an imaginary cylindrical surface having a diameter L and concentric with the hinge pins (5a, 5b) into four equal parts.

For convenience of explanation, the surface 5k shown in FIG. 3 (B) is referred to as "a surface where the corner member contacts the panel", 5s is referred to as "a surface parallel to the surface where the corner member contacts the panel", and 5t Is referred to as "a surface of the corner member parallel to the panel".

5q shown in the figure is a virtual line that intersects the above-mentioned "surface 5s parallel to the surface where the corner member contacts the panel" and "the surface 5t parallel to the panel of the corner member", and is orthogonal to the paper surface. And form a right angle.

The cylindrical surface 5h is formed so as to have the position and shape when the cylindrical surface is formed by adding a radius to the above-mentioned ridge angle 5q, and by this cylindrical surface, the "corner member comes into contact with the panel. The parallel surface 5s "and the" corner member surface 5t parallel to the panel "are connected.

The two cylindrical surfaces 5h are connected by a tangent plane 5i, but when the present invention is carried out, they can be connected by a concave surface 5j as shown by a broken line.

As shown in FIG. 7, when the two panels 4A and 4B face each other at about 90 ° and the hinge pins of the respective corner members 5 are connected by the clip 6A, both the panels 4A and 4B are relatively rotatable. Is hinged on.

When one of the two panels 4A and 4B is fixed, the other can freely rotate within a range of 180 °.

From the state of Fig. 7, turn panel 4B counterclockwise (counterclockwise) 90
When turned, it becomes as shown in FIG. 8 (A), and further counterclockwise rotation is prevented.

In this state of FIG. 8 (A), another clip
When 6B is installed, two panels 4A, 4 are installed as shown in Fig. 8 (B).
Bs are aligned in the same plane and fixed to each other.

Also, turn the panel 4B clockwise from the state of FIG. 7 (clockwise).
When turned to, the two panels 4A and 4B are folded as shown in FIG.

As shown in FIG. 10 (A), when two panels 4A and 4B are butted against each other at 90 ° and the clip 6 is attached to the hinge pin, the panel 4A rotates counterclockwise with respect to the panel 4B. Can not. If panel 4B is fixed in this state, panel 4A
Can function as a horizontal plate-like member that does not receive an upward external force like a shelf board.

When panel 4A is fixed in the state shown in FIG. 10 (A), panel 4B
Can rotate 180 ° counterclockwise. FIG. 10 (B) shows a state in which it is turned counterclockwise by 180 °. Panel in this state
The counterclockwise rotation of 4B is blocked.

As shown in FIG. 11 (A), when three panels 4A, 4B, 4C are butted against each other in a T shape and connected by clips 6A, 6B, 6C, they are adjacent to each other at a right angle (panels 4A and 4B). , And panel 4B and 4C) are fixed to each other and are the same as panel 4A.
It is fixed in the same plane as 4C.

Such a T-shaped connection, in particular the fixing of the pivot angle without the need for auxiliary fasteners, is a function not achieved by the conventional hinged connection device.

The T-shaped connection and the restriction of the rotation angle are possible because (a) two hinge pins are provided in parallel and (b) with respect to the distance L between the center lines of the two hinge pins. This is because the panel thickness (Z-axis direction dimension of the corner member) T is set to 2L, and the effect is exhibited by using a clip having a function of connecting two hinge pins having a centerline interval dimension L together. It

FIG. 11 (B) shows a further different use example. In this example, the three panels 4A, 4B, 4C are butted in a T shape,
4A and 4B are connected with clip 6A and the same as panel 4B.
4C is connected with a clip 6B, and further, panel 4D is connected with the above panel 4C by a clip 6C, and this panel 4D can form any angle within 90 ° with respect to the panel 4C. Moreover, the maximum opening angle is limited to 90 °.

For example, when an exhibition corner is constructed using a large number of panels, two adjacent panels can be rotated within 180 ° as described with reference to FIGS. 7, 8 (A), 9 and 10. Being able to do so greatly increases the degree of freedom in the layout of the exhibition corner. Moreover, as described with reference to FIGS. 8 (B) and 11 (B), being able to fix the angle between adjacent panels makes it possible to keep the layout of the exhibition corner constant. The layout does not change even if is pressed carelessly, bumped into it, or crawled, so it has a great practical effect.

Furthermore, as described with reference to FIG. 9, it is very convenient because it can be folded, and the unfolding / storing work can be performed quickly and easily, and the pattern can be changed quickly.

The clip shown in FIGS. 5 and 6 can be easily attached to two hinge pins simply by rotating the rotary locking member 6b fitted in the central hole 6a _-1 of the hook member 6a by 90 °. As I can put it on and take off,
The two panels can be connected and separated quickly and easily.
Therefore, the layout of the exhibition corner can be flexibly changed.

The above is a description of the practical effect when the panel provided with the corner member of the present embodiment is applied to the exhibition corner, the panel provided with the corner member of the present embodiment, for example, simple partitions, assembled furniture, Similar effects can be obtained in various applications such as office interiors and window displays.

Since the panel connection mechanism of the conventional example merely functions as a hinge, the panel provided with the conventional connection mechanism is a device having a function similar to a folding screen, which is an ancient furniture, and can be easily folded and unfolded. However, there was no holding power of the form. That is, each connecting portion is a device that freely rotates unless a separate member is attached and lacks reliability in maintaining shape (so-called twisting), but by applying the present invention,
Since the adjacent two panels can be fixed at an opening angle of a right angle or two right angles, the reliability of shape retention is significantly improved.

FIG. 2 shows a state in which the two panels 4A and 4B are arranged side by side and connected by a solid line, but the clip 6i shown by a virtual line is shown.
It is also possible to connect the panel 4i indicated by a virtual line to the upper and lower sides of the panel 4A using As for this vertical connection, as described with reference to FIGS. 7 to 11, the opening angles of the vertically adjacent panels are rotatably connected, fixed at right angles, or fixed at two right angles. It is possible to select an arbitrary connection state such as, for example, and it is easy to convert the connection state.

With this function, a large number of panels can be assembled three-dimensionally by applying the present invention.

FIG. 11C is a perspective view schematically illustrating an example of a three-dimensional assembled state.

As shown in FIG. 1, by providing two hinge pins 5a and 5b parallel to each other in the Y-axis direction and two parallel shafts 5c and 5d parallel to each other in the X-axis direction, FIG. The three-dimensional connection as shown in (3) becomes possible.

As can be easily understood from this embodiment, the Z axis in the present invention is in the thickness direction of the panel and corresponds to the corner member fixed to the panel in a one-to-one correspondence.
The axis can be converted arbitrarily. That is, the rectangular panel can be in any of the vertically long and horizontally long postures.

Therefore, in the present invention, two connecting shafts in the Y direction are arranged in the Z-axis direction, and the distance L between the center lines of the two connecting shafts is 1/2 of the thickness T of the corner member. Is the coordinate conversion, two connecting shafts in the X direction are arranged in a row in the Z axis direction, and the distance L between the center lines of the two connecting shafts is set to 1/2 of the thickness T of the corner member. Also, two connecting shafts in each of the X direction and the Y direction are arranged in a row in the Z-axis direction, and the distance L between the two connecting shafts is 1 / the thickness T of the corner member. It is meant to include 2.

Such corner members are attached to each of the four corners of one panel, and two parallel hinge pins are used (two each for a total of 16 hinge pins).
Book) is provided and is connected three-dimensionally as shown in FIG. 11 (C) to assemble three-dimensionally, for example, the hinge pins located at each part of P, Q, and R indicated by arrows are not used.

The unused hinge pin has no functional problem even if it is left unattended, but if the clip 6 is attached, the hinge pin does not appear in the appearance and is not likely to be lost. The clip 6 of the present example can have both the connecting function and the function as a cover member because the clip 6 engages with two hinge pins having the gap dimension L, and the gap dimension L is Because it is 1/2 of the thickness T of the panel.

[Effect of device]

As described above, when the corner member of the present invention is attached to the corner portion of the panel, an appropriate hinge pin is selected from the two parallel hinge pins of each panel while the adjacent panels are in contact with each other. By connecting with a clip, the connection state is (i) linked so that they can be rotated 180 ° to each other so that they can be folded, and both panels are aligned on the same plane to lock the rotation.
