Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a panel space expansion / contraction device capable of appropriately changing the space between two parallel panels, and a moving wall using the device. The present invention relates to display devices such as sliding doors and paintings.

<Conventional technology and its problems> Generally, in exhibition halls, conference halls, wedding halls, hotels, and the like of arts, the partition of the room as the hall can be changed depending on the type, form, atmosphere, etc. It would be preferable if possible, but what resulted from such a request was the moving wall. An entrance is formed in a part of the moving wall, and a normal door or a sliding door is provided at the entrance.

By the way, when a door is provided at the entrance of the moving wall, since the door can be originally formed to have the same thickness as the moving wall, when the door is closed,
The moving wall and the door are formed so as to be flush. Therefore, when the door is installed, when the door is closed, the presence of the door is inconspicuous in a distant place, which is extremely good.On the other hand, in the case of a sliding door, the door is stored inside a hollow moving wall. Therefore, the sliding door had to be formed thinner than the moving wall.

However, if the sliding door is formed in such a thin manner, when the sliding door is drawn out, that is, when the entrance is closed, the sliding door having a step in a part of the moving wall is conspicuous and not very well-formed. Moreover, even in the case of a moving wall having such an entrance, in a museum, paintings and the like may be exhibited in a sliding door portion in a closed state, and in this sense, such a sliding door is closed when the entrance is closed. It is highly desirable to avoid any step from the moving wall.

In general, when exhibiting paintings in an art museum, it may be hung from a hanger rail provided on the ceiling and hung on a moving wall (panel) that moves along the hanger rail, but this changes the atmosphere of the venue. For this reason, a box-shaped base is arranged in addition to the moving wall (panel), and a painting may be hung on the front or side surface. By the way, this box-shaped table is a literal box, has no problem when used for display, and has a very simple structure, so it is suitable for manufacturing. Even if it has a box-shaped table, it is not always used.

Also, not all of the plurality of platforms are used, and the point is that they are properly used depending on the size or type of the picture or the like to be displayed.

Therefore, those that are not used are stored and stored, but in this case, the conventional box-shaped table has no so-called elasticity (non-deformable), that is, when used and stored, Since they are equal in shape or size, they are bulky and require a large space for storage.

<Means for Solving the Problems> In order to solve the above-mentioned problems, a panel spacing expansion device according to the present invention (claim 1) arranges two panels in parallel, and In between, two types of X-shaped connecting rods, in which two straight rods are rotated at the intersection, are arranged horizontally and vertically, respectively, and left or right of the horizontal X-shaped connecting rod. And either the lower or upper end of the vertical X-shaped connecting rod is rotatably connected to the inner surface of the panel,
The other ends of the horizontal and vertical X-shaped connecting rods are slidably and rotatably connected to long holes formed in the inner surface of the panel.

Further, in order to solve the above-mentioned problem, a sliding door for a moving wall using the panel interval expansion and contraction device according to the present invention is provided between two panels constituting front and back of the sliding door body. Two types of X-shaped connecting rods, in which two straight bars are rotated at the intersection, are arranged horizontally and vertically, respectively, and the left or right of the horizontal X-shaped connecting bars and the vertical type are connected. Either the lower or upper end of the X-shaped connecting rod is rotatably connected to the inner surface of the panel, and the other ends of the horizontal and vertical X-shaped connecting bars are formed on the inner surface of the panel. And a panel interval expansion / contraction device slidably and rotatably connected to the elongated hole.

Furthermore, in order to solve the above-mentioned problem, a display device for a picture or the like using the panel interval expansion and contraction device according to the present invention (claim 5) has two panels arranged in parallel, and between these panels. Two types of X-shaped connecting rods, in which two straight rods are rotated at the intersection, are disposed horizontally and vertically, respectively, and left or right and vertical of the horizontal X-shaped connecting rod. Either the lower or upper end of the X-shaped connecting rod is rotatably connected to the inner surface of the panel, and the other end of the horizontal and vertical X-shaped connecting rod is connected to the inner surface of the panel. And a panel gap expansion / contraction device slidably and rotatably connected to the elongated hole formed in the above.

In the above description, the small panels are rotatably disposed at the openings at both ends of the two panels.

<Embodiment> Next, an embodiment of a panel space expansion and contraction device according to the present invention and a display device such as a sliding door for a moving wall and a picture using the device will be described with reference to the drawings. 2
This panel 1 is a panel that constitutes the front and back of the main body in the case of a sliding door or an exhibition device.

Reference numeral 2 denotes a connecting rod connecting the centers of two straight rods in an X-shape. The connecting rod 2 is rotatably connected by a bolt, a nut, or the like at an intersection 3 connected in an X-shape. It is. Also, the connecting rod 2 has an
The panel 1 is rotatably connected to a connection fitting 6 disposed on the inner surface of the panel 1 by bolts and nuts, and the other end is connected to
It is slidably and rotatably connected to the long hole 4 of the long hole-connecting metal fitting 7 provided on the inner surface of the single panel 1. Since the X-shaped connecting rod 2 is connected horizontally to the panel 1, it is referred to as a horizontal connecting rod in this document. The connecting rods 2 may be arranged in one set with respect to the two panels 1, but in order to stably perform the operation described later, two sets are arranged in series (not shown). Sometimes.

Reference numeral 2 'denotes a connecting rod arranged obliquely in the vertical direction to connect the two panels 1, and is referred to as a vertical connecting rod in this document. The structure of the connecting rod 2 'is exactly the same as that of the connecting rod 2 described above. That is, the center of the two straight bars is connected in an X-shape with bolts or nuts, and is rotatably connected at the intersection 3 '. One end of each of the vertical connecting bars 2' Is rotatably connected by bolts, nuts, and the like to a connection fitting 6 ′ or the like disposed on the inner surface of the panel 1, and the other end is connected to the panel 1.
Elongate hole 4 'such as elongate connection metal fitting 7' disposed on the inner surface
Slidably and rotatably.

Reference numeral 5 denotes a small panel which is rotatably disposed at each end (opening on both sides) of each panel 1 by using a hinge or the like. This small panel 5 is used when it is used for a display device such as a painting. In the case where the edge of panel 1 is closed and this surface is also used as a display wall for paintings or used as a sliding door, if the edge is left open, the appearance is poor. This is to improve the appearance.

<Operation> To change the distance between the two panels 1, it is sufficient to simply move the two panels 1 in the direction of approaching or moving away. In this case, horizontal or vertical connecting rod
Although the X-shaped angle of 2, 2 'changes, one end of each is pivotally connected to the inner surface of the panel 1 so that it rotates at that portion, and the other end of the panel 1 It rotates while sliding on the long holes 4, 4 'of the connecting metal fittings 7, 7' arranged on the inner side surface of the first fitting. In addition, the intersection points 3, 3 'of the X-shaped connecting rods 2, 2' also move. As a result, the interval between the panels 1 is always kept parallel at any position, and the panel 1 does not tilt at any position.

Then, after expanding the panel 1 to a predetermined width, the small panel 5 is rotated to close the space formed on the side surface of the two panels 1.

When the distance between the two panels 1 is to be reduced, the small panel 5 is rotated and housed in the inner surface of the panel 1 and the panel 1 is moved in the approaching direction, contrary to the above operation. It is good. Then, each of the X-shaped connecting rods 2,
The 2 'rotates while changing its angle, and can be brought as close as possible.

When this is used as a display device for a painting or the like, it is sufficient to perform the above operation, but when it is used as a sliding door, the distance between the panels 1 is reduced.
What is necessary is just to store it in the space formed in the moving wall. In this case, it is natural that the interval between the panels 1 in the narrowed state must be designed so as to be able to enter the space of the moving wall. All you have to do is lay a rail and hang it freely. After pulling out again,
That is, when closing the entrance, the interval between the panels 1 may be increased so as to correspond to the thickness of the moving wall.

<Effect of the Invention> As described above, according to the panel spacing expansion / contraction device according to the present invention and the display device such as a sliding door for a moving wall and a picture using the device, the distance between the two panels is made closer or farther away. This gives the panel space elasticity, and the space between both panels is always kept parallel at any position, so that it does not tilt in both wide and narrow directions. When it is used as a sliding door, it can be stored in the hollow part of the moving wall, and when it is pulled out, it can be made the same thickness as the moving wall. In other words, the display device can be formed into a proper shape when used, and can be compactly folded when not in use.
