[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the drawings. Reference numeral 1 shown in the drawings is a substantially square slide base in which a substantially square opening 2 is formed in the center. And the opening 2 itself is the slide base 1
It is in a state of being rotationally phased at a predetermined inclination angle with respect to the whole. In the illustrated example, a box-shaped storage portion 3 that communicates with the opening portion 2 is continuously formed on the back surface of the slide base 1. By opening and closing the opening portion 2, various articles are stored in the storage portion 3. It can be stored and taken out. Needless to say, the embodiments of the present invention and the applied examples thereof are not limited to those having such an aspect of forming a square overall shape or a box shape.

Then, the four opening / closing door plates 5 which slide and swing on the slide base 1 to open and close the opening 2 are supported so as to swing with each corner position on the slide base 1 as a swing fulcrum 4. The opening / closing door plate 5 is placed on the slide base 1. These four opening / closing door plates 5 are the same as each other and are identical in shape, and are formed by equally dividing the planar shape of the slide base 1, and at least one of the opening / closing door plates 5 is opened / closed. When swinging, the other three opening / closing door plates 5 are also swingably opened / closed via the opening / closing operation means 10.

Here, the opening / closing door plate 5 partitioned and formed on the slide base 1 is located at the center of the slide base 1 by the dividing line that divides the planar shape of the slide base 1 into equal parts. The apex itself of the slide base 1 is defined as the central top portion 6, and the slide base 1
The edge on the division line on the open side when the device itself swings open is defined as an open edge portion 7, and similarly, the edge on the division line on the opposite side on the closed side is the closed edge portion 8.
Please note. The opening / closing door plate 5 swings and slides while gradually increasing the opening formed by the closed edge 8 of the opening / closing door plate 5 itself on the surface of the opening 2 to open the opening side of the opening 2. At a position that almost matches the edge, and
When the ends of the central top portions 6 stop contacting the ends of the closed edge portions 8 of the adjacent opening / closing door plates 5, they are opened to a position where an opening of the opening portion 2 shape can be obtained. Further, after the opening, the center apex 6 of the opening / closing door plate 5 converges at the center position of the opening 2 so as to converge and open while sliding in the opposite direction and swinging so as to close the opening surface of the opening 2. The portion 2 is closed, and at the time of closing, the open edge portion 7 and the closed edge portion 8 are in close contact with each other between the adjacent opening / closing door plates 5.

As shown in FIG. 2, when the opening 2 is opened and closed by the four opening / closing door plates 5 of the slide base 1 having a substantially square shape in plan view, the side length L of the slide base 1 is L.
On the other hand, when the length of one side of the opening 2 is about 1/2 L, the opening 2 itself is inclined with respect to the slide base 1 at a rotation phase angle of about 13 ° 30 ′ (in the figure, (Counterclockwise) An opening 2 is formed in the center of the slide base 1.
Are arranged and formed. On the other hand, the dividing lines that form the opening / closing door plate 5 are formed in a cross-shaped line that is orthogonal to each other, and in the direction opposite to the rotation phase direction of the opening 2 itself (clockwise in the figure),
The slide base 1 is arranged on a line set by a rotation inclination angle of approximately 19 ° 35 ′. In addition, each opening / closing door plate 5 obtained by this cross-shaped dividing line
The swing center positions of the slide bases 5 are divided in the peripheral edge of the slide base 1 so as to swing the respective open / close door plates 5 in the same direction (counterclockwise in the drawing) that matches the rotational phase direction in the opening 2. On the long side that is longer than the corner of the slide base 1 with respect to the intersection formed by the demarcation lines, the length from the corner is approximately 9 / 100L with respect to the L, and also from the corner. On the short short side, the intersection point intersects L from the corner at a length of approximately 4.5 / 100L. At this time, the opening / closing door plate 5 has a rectangular shape in which the corner at the swing fulcrum 4 set at the corner of the slide base 1 and the center top 6 on the diagonal line are perpendicular to each other. Has become.

Incidentally, such a specific numerical example is an example when the opening / closing door plate 5 is opened / closed, and may be any one as long as the opening / closing operation by the opening / closing operation means 10 described later is smoothly performed. Of course, it is not limited to this.

Further, as shown in FIG. 3, the dividing line is, for example, each edge of the opening 2, that is, the closed edge portion 8.
Corresponding to the inward projecting curved line, even if the center of the slide base 1 has a gentle S-shaped curve intersecting in a substantially orthogonal shape, It's good. The dividing lines having such a curved line shape are abutting portions when the opening / closing door plates 5 are opened / closed, by the first opening / closing operation means 10 described later, and when they are pressed by each other, that is, the central top portion 6, the closed side. The edge portions 8 are surely brought into contact with each other, and there is an advantage that the opening / closing operation is made more reliable.

When one of the open / close door plates 5 is swung so as to open, the open / close door plates 5 are simultaneously swung without overlapping even in a part of the open / close door plates 5. An opening / closing operation means 10 for forming an opening communicating with the opening 2 in the central portion and simultaneously opening / closing the opening / closing door plates 5 will be described below. That is, FIG. 2 and FIG.
The first one shown in Fig. 1 is that the opening / closing operation of one open / close door plate 5 directly presses another open / close door plate 5 whose edge or center top 6 is adjacent in the swing direction, The opening / closing door plate 5 on the front side in the swing direction is sequentially opened / closed. The second one shown in FIGS. 4 and 5 is to open and close by simultaneously transmitting the opening / closing operation of one opening / closing door plate 5 to another via an appropriate transmission mechanism.

The first opening / closing operation means 10 shown in FIGS. 2 and 3 has the center of one of the opening / closing door plates 5 when the opening / closing door plate 5 is opened and rocked, that is, counterclockwise in the drawings. The top portion 6 hits the closed edge portion 8 of another adjacent opening / closing door plate 5 on the front side in the swinging direction, the adjacent opening / closing door plate 5 is swung open, and similarly, the adjacent opening / closing door plates 5 are sequentially moved. The swing is released (see FIG. 1). Then, the closed edge portion 8 reaches the opening edge position of the opening portion 2, and at the same time, the open edge portion 7 which is the open-side edge of the center top portion 6 is closed edge portion 8.
Of the slide base 1 comes into contact with the edge of the slide base 1 on the side of the edge without a gap, and stops at a position where the central top 6 cannot press and swing the opening / closing door plate 5. In this stopped state, the respective opening / closing door plates 5 are in the same abutting state as those adjacent to each other, and all the opening / closing door plates 5 open the opening 2 in a balanced state.

On the contrary, when closing the opening / closing door plate 5, if any one of the opening / closing door plates 5 is closed and swung, that is, is swung in the clockwise direction in the figure, the closed edge portion 8 thereof is swung. It hits the central top portion 6 of another adjacent opening / closing door plate 5 on the front side in the moving direction, closes and swings the adjacent opening / closing door plate 5, and similarly,
The opening / closing door plates 5 adjacent to each other are sequentially rocked and closed. Then, the central apex portion 6 converges on the central position of the slide base 1 and stops at the position where the closed edge portion 8 abuts the entire adjacent open edge portion 7 without a gap. In this stopped state, the respective opening / closing door plates 5 are in the same abutting state as those adjacent to each other, and all the opening / closing door plates 5 close the opening 2 in a balanced state.

In the second opening / closing operation means 10 shown in FIGS. 4 and 5, the swing of one opening / closing door plate 5 simultaneously swings and opens the other opening / closing door plate 5 via the transmission mechanism. In the illustrated example, the transmission mechanism is formed on the rear surface of the slide base 1 so as to be integrated with the opening / closing door plate 5 on the front surface of the slide base 1.
Swing plates 12 that swing together with the open / close door plates 5 via swing shafts 11 that penetrate the slide base 1 are provided so as to correspond to the open / close door plates 5, respectively. In between, the swing link 13 is swingably connected between the open end of the one swing plate 12 and the closed end of the other swing plate 12. Reference numeral 14 in the figure is a spacer for setting an appropriate interval between the slide base 1 and the rocking plate 12 so that the rocking link 13 linked to the rocking plate 12 can smoothly rock. .

Here, when any one of the open / close door plates 5 is opened by swinging (counterclockwise in the figure), the swing plate 12 is integrally swung in the opening direction via the swing shaft 11. The swinging of the swinging plates 12 causes the adjacent swinging plates 12 to swing in the same direction via the swinging link 13. As a result, the adjacent open / close door plates 5 are integrally swung via the swing plate 12 and the swing shaft 11, and the open / close door plates 5 adjacent to each other are swung in synchronization with each other. The central apex portion 6 stops contacting the ends of the closed edge portions 8 of the open / close door plates 5 and is opened to a position where an opening having the shape of the opening portion 2 is obtained.

On the contrary, to close one of the open / close door plates 5 in the open state, similarly, the other open / close door plate 5 is moved through the swing shaft 11, the adjacent swing plate 12, and the swing link 13. 5 is also closed synchronously, and the central top portion 6 of the opening / closing door plate 5 converges at the center position of the opening portion 2 to close the opening portion 2.

The opening / closing operation by the second opening / closing operation means 10 is performed in synchronism with each other of the opening / closing door plates 5 on the slide base 1, and the slide base is open during the opening / closing operations other than the open state and the closed state. The open / close door plates 5 on 1 do not abut each other (see FIG. 4).

The transmission mechanism constituting the second opening / closing operation means 10 has a swing link structure as shown in the drawing, especially when the slide swing direction of the open / close door plate 5 is along the vertical line. When one opening / closing door plate 5 is rocked in synchronization with the other opening / closing door plate 5, the opposing members rock in opposite directions so as to cancel each other by weight. The force enables a smooth opening and closing operation. Further, in any case, it is possible to operate extremely smoothly by the rotation moment, the inertia moment, and the like, and it is particularly suitable for being configured as a large one.

Of course, the transmission mechanism is not limited to the swing link structure as shown in the figure, but may be a belt, a chain, a gear, a cam, or any other appropriate interlocking means, and its drive source. It is also possible to use a motor to automatically open and close it without the need for human intervention.

However, when it is assumed that the substantially square opening 2 is formed on the slide base 1 having a substantially square shape in the plane shown in the figure, the dividing line is formed on the edge of the slide base 1. Although the rotation inclination angle is set to approximately 19 ° 35 ′, if the rotation inclination angle is larger than this setting angle, when the opening / closing door plates 5 swing, they abut each other. This is not preferable because they do not stop but swing individually, and simultaneous blocking operations cannot be ensured. On the other hand, if the rotation inclination angle is smaller than this set angle, the opening / closing door plate 5 swings so that the closed edge portion 8 does not reach the opening edge position of the opening portion 2 and the opening area becomes smaller. , Not preferred. Of course, irrespective of this, for example, the opening shape of the opening 2 may be a substantially square shape, and one side length thereof may be smaller than about 1/2 L of one side length L of the slide base 1. In this case, the rotation inclination angle of the dividing line itself may be smaller than about 19 ° 35 ', and the opening area of the opening 2 can be adjusted and set in advance by setting the rotation inclination angle.

Further, depending on the relationship between the position of the swinging fulcrum 4 of the opening / closing door plate 5 and the rotation phase angle of the dividing line that divides the opening / closing door plate 5, the swingability of the opening / closing door plate 5 and the opening portion. It is obvious that the opening shape of the second opening, the size of the opening area, and the like are determined, and the setting of these conditions is not limited to that of the specific example described above along with which opening / closing operation means 10 is adopted. Then, when the adjacent opening / closing door plates 5 simultaneously swing and rotate, the central tops 6 converged on the central portion of the slide base 1 are separated from each other between the adjacent opening / closing door plates 5 and swing. The rocking locus drawn toward the outside of the slide base 1 at the front in the same direction is adjacent to the front in the rocking direction and simultaneously swings similarly. It does not enter into the swing locus of the line segment drawn by when the same time elapses after the start of swing.

In the embodiment of the present invention, the slide base 1 formed in a substantially square shape in a plane as shown in the figure and the opening 2 formed in a substantially square shape corresponding to the slide base 1 have been described. The slide base 1 may be circular, triangular, pentagonal, hexagonal or other regular polygonal shape, and the opening 2 may be appropriately polygonal. Is.

Next, with reference to FIG. 6, an application example of the opening / closing device according to the present invention will be described by taking as an example the case where the opening / closing device is constructed as a mirror having a hidden shelf formed therein. The plate 9A is arranged and partitioned, and the surface of the opening / closing door plate 5 is formed into a mirror surface so that the opening 2 rotating in phase with the slide base 1 at a predetermined inclination angle is horizontal. (3) Suspended and supported by the locking projections 9B provided on the outside. At this time, the entire slide base 1 is in a state of being inclined at a rotation phase angle with respect to the installed horizontal plane, but the inclination itself exerts an accent on the installation surface.

Although not shown, the box-shaped storage portion 3 protruding from the rear surface of the slide base 1 itself may be used as a base, or appropriate legs may be attached to the rear surface of the slide base 1 to form a table. . At this time, the open / close door plate 5 serves as a table top plate, on which tableware and the like can be opened and closed, and seasoning containers, knives, forks and the like can be taken in and out.

Similarly, an incandescent lamp, a fluorescent lamp, or the like can be arranged in the storage section 3 to form a lighting device. At this time, the opening / closing door plate 5 becomes a shade, and the irradiation range of the light source is adjusted. Enables light and dark adjustment.

Furthermore, a ventilation fan device or the like can be arranged in the storage section 3 to constitute an air conditioner. At this time, the opening / closing door plate 5 serves as an opening / closing lid, and the amount of air to be ventilated is adjusted, and the air produced by this is adjusted. Enable harmony.

In addition, it has versatility so that it can be applied and implemented in a wide range of various storage containers, interior products, stage equipment, and various equipment.

[0043]

As described above, according to the present invention, a plurality of divided opening / closing door plates 5 for opening / closing the opening 2 formed in the slide base 1 are set in the outer position around the opening 2. Since the fulcrum 4 is connected on the same plane on the slide base 1 and is slidably opened / closed and oscillated, and when closed, it is converged and matched with the center of the opening 2. Can have different opening / closing modes and have an interesting opening / closing structure. Therefore, it can be applied to various objects such as mirrors, tables, lighting fixtures, air conditioners, etc., and can be made versatile. it can.

Further, among the plurality of open / close door plates 5 stacked on the slide base 1, by opening / closing at least one of the open / close door plates 5, other open / close door plates 5 are also opened via the open / close operation means 10. The doors 5 can be opened and closed in a driven manner, and the respective opening / closing door plates 5 at this time do not overlap each other even in a part thereof.
Simultaneously swing and slide 2 at the center of the slide base 1
Can be opened and closed.

When the opening / closing door plate 5 is opened to the maximum, the closed edge 8 of the opening / closing door plate 5 reaches the opening edge position of the opening 2, and at the same time, the opening-side edge of the central top 6 is opened. The open side edge portion 7 is abutted with no gap on the side edge side edge of the slide base 1 in the closed side edge portion 8 of the open / close door plate 5 adjacent on the open side, so that the open / close door plate 5 itself swings open. Therefore, the opening operation of the opening / closing door plate 5 is stopped while the opening 2 remains open, and this is maintained.

On the contrary, when closing the opening / closing door plate 5, the central apex 6 of each of the opening / closing door plates 5 oscillating in the opposite direction converges to the central position of the slide base 1, and the closing edge 8 is closed. Since all the open / close door plates 5 stop adjacent to each other at the open edge portions 7 with no gaps, all the open / close door plates 5 are closed.
The opening portion 2 is closed in a balanced state, and the opening / closing operation of the opening / closing door plate 5 is performed by directly swinging the opening / closing door plate 5, which is extremely smooth.

Further, the first pressing type opening / closing operation means 10
Is an opening / closing door plate 5 that has been opened and closed by abutting a central top portion 6 of the opening / closing door plate 5 and a closed edge portion 8 of another adjacent opening / closing door plate 5 on the front side in the rocking direction. Also, since all of the open / close door plates 5 can be opened / closed without requiring a special transmission mechanism, they can be reliably operated even though the structure is simple.

The second simultaneous swing-type opening / closing operation means 1
No. 0 has a swing plate 12 integrated on the back surface of the slide base 1 via an open / close door plate 5 for swinging open / close and a swing shaft 11, and swing of the swing plate 12 via a swing link 13. Since another adjacent rocking plate 12 is rocked in the same direction,
The swinging of the open / close door plates 5 on the slide base 1 is carried out at the same swing angle and in perfect synchronization. Therefore, the whole is smoothly swung by the symmetrical rotation moment and inertia moment.

In particular, the opening / closing door plate 5 according to the present invention is combined with the adoption of various structures in the opening 2 and the housing 3.
For example, a mirror surface may be used as a whole mirror, a table top plate may be used as a whole table, and a shade may be used as a whole lighting device, and the like, and the like. It is versatile and can be used for various things without being damaged.
