Description

The present invention relates to a single panel set and a multi-panel that can be used as a lightweight, foldable multi-panel (which can be removably attached to an adherend when used as a polygonal mirror) by connecting multiple single panels that make up the single panel.

Foldable multi-panel panels, which are made by connecting multiple single-panel panels, are often used as everyday items and work tools.
A typical example is a foldable three-way mirror.

Usually, when a person looks at themselves in a mirror, they fix the single-sided mirror and rotate their body horizontally in front of the mirror's surface to see their own front, side, and back (hereinafter, the side and back are also referred to as the "back side") in the single-sided mirror.

However, it is also possible for a person to face their own front side toward the mirror surface of a fixed single-sided mirror and fix a three-way mirror with its mirror surface facing the person's back side, so that the person can see their own back side reflected in the three-way mirror as it is reflected in the fixed front mirror surface (for example, Patent Document 1).

Patent document 1 states that the three-way mirror for reflecting the rear side of a person is preferably a "ceiling storage type" ("ceiling hanging fixed type" (Patent document 1, paragraph 0010)) that is connected to a support extending from the ceiling as shown in Figure 1 of Patent document 1, or a "pedestal floor-mounted type" (Patent document 1, paragraph 0007).

An example of a "pedestal-mounted floor-mounted system" is the system disclosed in Figure 1 of Patent Document 2.

Utility Model Registration No. 3114105 Japanese Patent Application Laid-Open No. 10-137032

However, in the three-sided mirrors disclosed in Patent Documents 1 and 2, in which the mirror surface faces away from the person, even though each single mirror can be folded and unfolded freely, each single mirror is quite heavy, and when the weight of accessories such as a storage case is added, it cannot be said that the mirrors are suitable for folding and carrying.

The present invention aims to provide a set of single-panel plates (hereinafter referred to as a "single-panel plate set") that can be used to form a bendable, foldable, lightweight multi-panel (which can be removably attached to an adherend when used as a polygonal mirror), and a multi-panel plate formed from the single-panel plate set.

The single-panel plate (1) of the present invention 1 is shown in a front view (a1), a plan view (b1) and a right side view (c1) in a second embodiment, and in a front view (a2), a plan view (b2) and a right side view (c2) in a third embodiment. 1 shows examples of the form of the single-face plate (1) in the present invention 1, in which (a) is a single-face plate whose surface (SF) has an elliptical shape, and (b) is a single-face plate (1) whose surface (SF) has a parallelogram shape. These are examples of planar views of the multi-panel panel (2) of the third invention, which is composed of the single-panel panels (1) of the first invention, and which is a four-panel panel. The thick straight lines are schematic diagrams of the side of the single-panel panel (1) in plan view, and the black circles are schematic diagrams of the connecting parts (JT) connecting the single-panel panels (1) to each other in plan view. (a) Adjacent single-panel panels (1) are all connected by connecting parts. (b), (c), (d), and (e) there is no connection at one point, and four single-panel panels (1) are connected by bending. (f) there is no connection at one point, and the single-panel panels (1) are connected straight without bending. (g) there is no connection at one point, and the single-panel panels (1) are folded. The multi-panel (2) of the third invention, which is composed of the single-panel (1) of the first invention, is a four-panel, and the bendable sheet (SJT) constituting the connecting part (JT) is (a) connected across the edge parts of both single-panel panels (1) only in a portion of the direction of the connecting edge parts, or (b) connected across the edge parts of both single-panel panels (1) along the direction of the connecting edge parts. In the four-panel panel of form (b), (c) the single-panel panels (1-1 and 1-4) at both ends are folded at the connecting parts (JT-1 and JT-3), and (c1) are folded onto the adjacent inner single-panel panels (1-2 and 1-3), and (c2) the adjacent single-panel panels (1-2 and 1-3) further inside are folded at the connecting part (JT-2). 1 is a schematic diagram in plan view of a removable adhesion mode of an adhesive part (AM) of a bent four-sided plate (2) to a surface of an adherend (AH). (a) Adhesion mode to a vertical surface of an adherend (AH) when an adhesive part (AM) is present at a joint (JT) of the four-sided plate (2).

(c) Adhesion mode to a vertical surface of an adherend (AH) when an adhesive part (AM) is present on the surfaces of four single-sided plates (1) of the four-sided plate (2). (d) Adhesion mode to an inclined surface of an adherend (AH) when an adhesive part (AM) is present on the surface of one single-sided plate (1) of the four-sided plate (2). As an example of an inclined adherend, as shown in FIG. 5-1 (d), an adherend stand (AHS) having a flexible arm (AHF) that can freely change its orientation is prepared by connecting an adherend plate (AHP) to a mounting base (AHM), as shown in FIG. 5-1 (d). The adherend stand (AHS) is placed in a desired location, and the adherend plate (AHP) is oriented and angled in a desired direction, and the adhesive portion (AM) of the four-sided plate (2) is bonded to the surface of the adherend plate (AHP). 1A and 1B are schematic front views of the bonding pattern of a bent four-sided panel (2) with an adhesive (AM) at the edge of a single-sided panel (1) to a vertical surface of an adherend (AH). (e) The bonding pattern when the adhesive (AM) is set in a direction along the connecting part (JT). (f) The bonding pattern when the adhesive (AM) is set in a direction perpendicular to the connecting part (JT). This is a schematic diagram of an embodiment in which a single-panel plate (1) at the end of a four-panel plate (2) can rotate in a twisted direction relative to an adjacent single-panel plate (1) at a joint (JT). This is an example 1 of a bendable sheet joint in which single panels are joined by a bendable sheet (SJT) that is removable and that spans the edges of both single panels (1) at the connecting edge of adjacent single panels (1) so that the four-panel panel can be bent and unfolded and can maintain its bent shape. In example 2 of a bendable sheet joint in which a bendable sheet (SJT) is used to connect a single panel (1) to an adjacent single panel (1) so that the multi-panel panel (2) can be bent and unfolded and maintain a bent shape, and the bendable sheet (SJT) is attached to the connecting edge of the adjacent single panel (1) and can be removed from the connecting edge of the adjacent single panel (1). (a) is an example in which the bendable sheet (SJT) has a sheet joint belt (SJTB) passed through a sheet joint belt loop (SJTBC) and fixed with a sheet joint belt stopper (SJTBS), and (b) is an example in which the bendable sheet (SJT) has a sheet joint belt (SJTB) passed through a sheet joint slit (SJTS) and fixed with a sheet joint belt stopper (SJTBS). This is an example of a rotation fixing joint in which a hinge (HG) or torque hinge (TH) is installed along the direction of the edge portion of the connecting side of adjacent single-panel panels (1) so that it can be inserted and removed from each other, and the rotation of the hinge (HG) (which can be replaced with a torque hinge (TH)) is fixed or released when they are inserted into each other (for example, Figures 9-1 (a) and (b)). FIG. 1 shows an example of a four-sided panel (2) connected to a single-sided panel (1) by a rotating and fixed joint, where (a) is a front view and (b) is a plan view. These are examples of magnetic joints in which at least the edge portions of the single-panel panels (1) are formed from a magnetic material and adjacent single-panel panels are connected by magnetic force (part of the connecting parts is fixed with a bent-form fixing joint (3) to maintain the bent form). (a) is an example of a four-sided panel (2) in which four single-panel panels (1) are arranged in parallel and connected with a magnetic joint; (b) is an example of a four-sided panel (2) in which four single-panel panels (1), all of whose edge portions are formed from a magnetic material, are connected two by two vertically and two by two horizontally; and (c) is an example of a six-sided panel (2) in which four single-panel panels (1) are arranged in parallel and connected with magnetic joints, and further a single-panel panel (1) is connected above and below the second single-panel panel (1) from the left. FIG. 1 shows an example of a slide rail joint in which slide rails (SR) are attached to the side edges of the bent portions of adjacent single-panel panels (1), slide hooks (SH) are inserted into the slide rails (SR) so that they can move freely along the rails, and each slide hook (SH) is inserted into a slide ring rail (SRR) sandwiched between the slide rails (SR) and the slide hooks (SH) to connect them together; (a) is a front view of the joint, (b) is a plan view of the joint, and (c) is a plan view of an example of a four-panel panel connected with a slide rail joint. This is an example of an inner string joint in which grooves are created in a grid pattern across the entire surface of a single-panel panel (1) in the surface or interior direction, through which a string-like material (ST) such as thread, rubber or wire can pass, and the string-like material (ST) is passed through the grooves to connect adjacent single-panel panels (1) across each other, allowing the adjacent single-panel panels to bend and unfold. This is an example of a retractable joint with a retractable connection, in which the side of one edge of the single-panel panels (1) connected at their edges has a storage space (SP) for a bendable sheet (SJT), and (a) once the bending shape is determined, (b) the bendable sheet (SJT) can be stored in the storage space (SP) through the entrance/exit (SPM) of the storage space (SP), and the distance between adjacent single-panel panels (the gap between the connected edges) can be adjusted to be small (δ can be minimized or to about 0). This is an example of a single-panel slide-type retractable joint that provides an entrance (SPM) and storage space (SP) for inserting and removing adjacent single-panel panels (1) on the side of the joint of the single-panel panels (1), and allows the single-panel panel (1) to be inserted and removed along a slide rail (not shown) in the storage space (SP). The edge of the single-panel panel (1) to be inserted and removed is connected to the entrance (SPM) of the storage space (SP) by a joint mechanism (not shown), and when the single-panel panel (1) to be inserted and removed is fully exposed from the entrance (SPM) of the storage space (SP), the joint mechanism allows the exposed single-panel panel (1) to assume a bent shape while maintaining its connection with the entrance (SPM) and the single-panel panel (1) with the storage space (SP). This is an example of a bent form fixed joint in the form of a bifurcated clip (CL) connected by a clip joint (CLJT) (preferably a hinge or torque hinge) that can maintain an arbitrary angle φ. The clip joint (CLJT) is adjacent to the side of the bifurcated clip (CL), (a) is an embodiment in which the length from the hinge part to the bifurcated clip (CL) is short, (a-1) is a plan view thereof, (a-2) is a front view thereof, (a-4) is a side view thereof, and (a-3) is a plan view when the clip joint (CLJT) is bent at an angle φ. (b) is an embodiment in which the length from the hinge part to the bifurcated clip (CL) is long, (b-1) is a plan view thereof, (b-2) is a front view thereof, (b-4) is a side view thereof, and (b-3) is a plan view when the clip joint (CLJT) is bent at an angle φ. This is an example of a bent shape fixed joint in the form of a bifurcated clip (CL) connected by a clip joint (CLJT) (preferably a hinge or torque hinge) that can maintain an arbitrary angle φ. (c) shows a hard plate (HP) made of a metal plate or resin or the like twisted perpendicular to the surface of the clip (CL) connected to the right end of the left clip (CL), and a hard plate (HP) made of a metal plate or resin or the like twisted perpendicular to the surface of the clip (CL) connected to the left end of the right clip (CL), with the ends of both hard plates (HP) overlapping and fixed by a tightening/loosening mechanism such as a screw so that the rotational state of both hard plates (HP) can be tightened or loosened. (c-1) is a plan view, (c-2) is a front view, (b-4) is a side view, and (c-3) is a plan view when the clip joint (CLJT) is bent at an angle φ. (d) is an example of a bent shape fixed joint in the form of a bifurcated clip (CL) connected by a flat hinge type clip joint (CLJT) that can maintain an arbitrary angle φ. (d-1) is its plan view, (d-2) is its front view, (d-4) is its side view, and (d-3) is a plan view when the clip joint (CLJT) is bent at an angle φ. This is an example of a four-panel (2) whose bending form is fixed by a bending form fixing joint. (a) This is an example of an example when the bending form fixing joint of the embodiment (b) in Fig. 15-1 is used. The bending form fixing joint can slide along a slide rail (SR) provided near the upper end of the single-panel (1). (b) This is an example of an example when the bending form fixing joint of the embodiment (a) in Fig. 15-1 is used. FIG. 15-2(c) shows an example of a multi-panel plate in which an adjacent single-panel plate (1) is clipped with the clip (CL) of the bifurcated clip joint (CLJT). (a) is an enlarged plan view of the bifurcated clip joint (CLJT). (b-1) and (b-2) are front views of adjacent single-panel plates (1) clipped in a flat state (φ≒0°), (b-1) is an example of δ>0, and (b-2) is an example of (b-1) in which the single-panel plate (1) is slid along the clip (CL) to δ≒0. (c) is a perspective view of an example of a clipped adjacent single-panel plate (1) in a bent state (φ>0°), showing that the clipped single-panel plate (1) can slide in the direction (indicated by the arrow) of the bifurcated clip joint (CLJT) along the clip (CL) while remaining in the bent state. The front views of an example of a four-panel plate (2) formed by connecting four single-panel plates (1) with clips (CL) of the bifurcated clip joint (CLJT) shown in Figure 15-2 (c), (a-1), (a-2), and (a-3) show the front side, and (b-1) and (a-2) show the back side. (a-1) is an example of a configuration in which each clip (CL) of the bifurcated clip joint (CLJT) clips each of the adjacent single-panel plates (1) to fix the four-panel plate (2) in a flat state (φ≒0°) and δ≒0. (a-2) is an example of a configuration in which one clip (CL) of the bifurcated clip joint (CLJT) clips both of the adjacent single-panel plates (1), thereby more firmly fixing the four-panel plate (2) in a flat state (φ≒0°). In (a-3), the first and second single-panel panels (1) from the left are clipped to the clips (CL) of the bifurcated clip joint (CLJT) and bent (φ>0°), and the distance δ between the second and third single-panel panels (1) from the left is adjusted to be large, and the third and fourth single-panel panels (1) from the left are flat (φ≒0°) and clipped with one clip. In (b-1) and (b-2), the bifurcated clips (CL) of the bifurcated clip joint (CLJT) that can maintain any angle φ are used to clip both the upper and lower edges of adjacent single-panel panels in the width direction, and the clip (CL) that clips the upper edge and the clip (CL) that clips the lower edge are connected by a clip holder (CH). This is an example of a bent form fixed joint in which a storage space (SP) is provided along the edge of the adjacent sides of adjacent single-panel panels (1), a engagement bar (CB) is installed along the edge within the storage space (SP), and a fitting clip (SICL) is fitted across adjacent engagement bars (CB) to connect adjacent single-panel panels (1).

[Single panel]
The single-faced plate (1) in the present invention 1 has two opposing surfaces (SF), and each surface (SF) of the two surfaces (SF) has an edge portion (ED) (for example, FIG. 1).

The two opposing surfaces of the single-panel panel (1) in the present invention 1 refer to the surfaces of the single-panel panel (1) facing the outside (hereinafter also referred to as "surfaces of the single-panel panel" or "surfaces" (SF)) (e.g., FIG. 1(a)). The interior of the single-panel panel (1) sandwiched between the surfaces (SF) of the single-panel panel may be partially hollow (e.g., FIG. 1(b1)(c1)) or solid (FIG. 1(b2)(c2)), as long as the surfaces (SF) of the single-panel panel are structured to maintain a certain distance between them. In the following, the surface with the smallest area that connects the edge portions (ED) of the two opposing surfaces is referred to as the "side surface of the single-panel panel" (SD).

The form of the surface (SF) of the single-panel plate may be flat, convex or concave, and the forms of the surfaces (SF) of the two single-panel plates may be different. However, from the viewpoint of compactness of the folded state of the multi-panel plate constituted by the single-panel plate (1),

The shape of the surface (SF) of the single-panel plate may be any shape surrounded by curves and/or straight lines, such as an ellipse including a circle (e.g., FIG. 2(a)), a parallelogram (e.g., FIG. 2(b)), a triangle, a polygon, a star, a cloud, etc. However, from the viewpoint of compactness of the folded state of the multi-panel plate (2) composed of the single-panel plate (1),
Preferably, it is an ellipse including a circle, a parallelogram, a triangle, a polygon including a regular polygon, a star or a cloud, more preferably an ellipse, a triangle, a parallelogram or a regular polygon, even more preferably a triangle, a rectangle or a regular hexagon, and even more preferably a rectangle.

The area of the surface (SF) of the single-panel plate is preferably 100 to 1500 cm2, more preferably 150 to 1000 ^cm2 , even more preferably 200 to 800 ^cm2 , even more preferably 250 to 600 cm2, even more preferably 300 to 500 ^cm2 , and even more preferably 300 to 400 ^cm2 , from the viewpoint of compactness when folded into a multi-panel plate ( ² ) composed of a single-panel plate ( ¹ ).

The length of the straight line that intersects the contour of the surface (SF) of the single-panel panel in a front view at two or more points is the longest line segment cut by said contour (Figure 2(a)) (if the contour of the surface of the single-panel panel (1) in a front view is a parallelogram (including one with rounded corners ₎ (Figure 2(b)), the longest line segment cut by said contour that is parallel to the long side of said parallelogram) _LLG (hereinafter also referred to as "length") (Figure 2b),
A straight line perpendicular to a line segment _LLG that intersects with the outline of the front view of the surface (SF) of the single-panel panel at two or more points and is cut by the outline, the longest line segment _LWD (hereinafter also referred to as _{" width} "), is _determined as follows from the viewpoint of ease of use of the single-panel panel and the multi-panel panel (2):

More preferably, it is 100/400 to 100/100, and even more preferably, it is 100/300 to 100/100,

The second and third examples of the single-panel plate (1) may be formed by laminating plate 1 (PL1) and plate 2 (PL2), or by further laminating a core plate (PLC), and the outer shape of the laminate may be formed by integral molding such as extrusion molding of resin or metal.

[Single panel set]
The single-panel plate set of the present invention 1 is composed of a plurality of specific single-panel plates in the present invention 1 described above, and may be configured together with a connecting member having a joint mechanism described later, or an attachment stand (AHS) having an attachment plate for suitably achieving the adhesive function of the multi-panel plate (2) as shown in Figure 5-1 (d), so that the multi-panel plate (2) of the present invention 3-1 formed by connecting the single-panel plates (1) can have a specified function.

<<The present invention 2>>
The present invention 2 is a single-panel set composed of a plurality of single-panel panels,
The single-sided plate has two opposing surfaces, each of the two surfaces having an edge;
The plurality of single-panel panels can be connected and disconnected to each other at the edge of each single-panel panel;
The connected single-panel panels are provided at the edge portions,
can be bent at a predetermined range or at any angle φ relative to each other;
Can be folded and unfolded relative to each other;
an edge portion of a single-panel panel adjacent to one of the pair of connected single-panel panels straddles a connection portion between the one single-panel panel and the adjacent single-panel panel and contacts one surface of the one single-panel panel, so that the angle between the one single-panel panel and the adjacent single-panel panel does not exceed a predetermined angle;
moreover,
When the single-faced plate is a mirror body and the multi-faceted plate is configured as a polygonal mirror,
The polygonal mirror composed of the connected single-faced plates can be removably adhered to an adherend,
When the connected single-panel panels are used under the earth's gravity environment, the weight of the single-panel panel set is 500 g or less.

In comparison with Invention 1, Invention 2 has the following features:
The first aspect of the present invention is that "the connected single-panel panels can be bent at the edge portions while maintaining a predetermined or arbitrary angle φ with respect to each other," whereas the second aspect includes an embodiment in which "the connected single-panel panels cannot be bent at the edge portions while maintaining a predetermined or arbitrary angle φ with respect to each other."
It differs in that the manner of connection is specified as one in which "an edge portion of a single-panel panel adjacent to one of a set of connected single-panel panels straddles the connection portion between the one single-panel panel and the adjacent single-panel panel and contacts one surface of the one single-panel panel, so that the angle between the one single-panel panel and the adjacent single-panel panel does not exceed a predetermined angle."

However, since the present invention 1 also includes this particular connection mode, the specific connection mode will be explained in detail in the [Joint mechanism] of the present invention 3-1 (Joint mechanism 10: Connection part shielding joint).

The above description of the single-panel plate constituting invention 1 is applicable to the single-panel plate constituting invention 2.

The single panel set of the present invention 2 is composed of a plurality of specific single panels of the present invention 2, and the single panel set may be formed by applying a connecting member having a joint mechanism, which will be described later, or the adhesive function of the multi-panel panel (2) as shown in FIG. 5-1(c) to the multi-panel panel (2-2) so that the multi-panel panel (2-2) of the present invention 3-2, which is formed by connecting the single panels (1), can have a specified function.

<<The present invention 3>>
[The present invention 3-1]
The multi-panel plate (2) of the present invention 3-1, which is the present invention 3 formed by connecting a plurality of single-panel plates (1) constituting the present invention 1, has the following functions 1 to 3.

(Function 1) The edges of each single panel (1) can be connected and disconnected.

(Function 2) The connected single-panel panels (1) can be bent at the edge portions of each single-panel panel (1) while maintaining a predetermined or arbitrary angle φ relative to each other.

(Function 3) The connected single-panel panels (1) can be folded and unfolded relative to each other.

Invention 1, function 1 allows a single-panel set to be made that can be used to form a multi-panel (2) using any number of single-panel panels (1).

Invention 1, function 2 allows the multi-panel plate (2) to be formed into any curved shape when it is made up of any number of single-panel plates (1).

For example, if four single-sided panels (1) are connected to form a four-sided panel (2), the four-sided panel (2) will look like this in plan view:
The bent shapes include a square (a square prism with single-panel panels (1) as sides) (Fig. 3(a)), a bent shape with one corner of the square open (Figs. 3(b)(c)(d)), a W-shape (a multi-panel panel in the shape of a folding screen) (Fig. 3(e)), a straight line (a flat multi-panel panel) (Fig. 3(f)), and a folded shape in which the bending angle φ between adjacent single-panel panels is minimized (Fig. 3(g)).

Bent forms (e.g., Fig. 3(g)) other than the folded form (e.g., Fig. 3(a) to (f)) can be called unfolded forms.

In Figure 3, the thick straight lines are schematic diagrams of the side of the single-panel panel (1) in plan view, and the black circles are schematic diagrams of the connecting parts (JT) (which can be constructed, for example, by a joint mechanism described below) that connect the single-panel panels (1) in plan view (the same applies to Figures 5-1, 9-2, 18 and 19).

In the bending form of the multi-panel (2), when the connected single-panel (1) is bent (including a flat multi-panel in which the bending angle φ of adjacent single-panel (1) is approximately 180°), the length δ (for example, FIG. 4(a)(b)) of the smallest line segment cutting the straight line where the contours of the opposing edges of the edges of the adjacent single-panel (1) of the joint (JT) intersect with the opposing contours (hereinafter also referred to as the "distance between adjacent single-panel panels") is preferably 0 to 5 cm, more preferably 0 to 3 cm, even more preferably 0 to 2 cm, even more preferably 0 to 1 cm, even more preferably 0 to 5 mm, even more preferably 0 to 3 mm, even more preferably 0 to 2 mm, even more preferably 0 to 1 mm, from the viewpoint of visual aesthetics in which the joint mechanism constituting the joint (JT) is not visible and the surface (SF) of the single panel appears as a continuous plane as possible, and it is preferable that δ can be adjusted within these ranges (note that δ = 0 is also set when adjacent opposing edges overlap).

In the case of a polygonal mirror (2), when the polygonal mirror (2) is in a flat form, the smaller δ is, the better it functions as a full-length mirror that allows a continuous reflection of the entire body.

In the present invention 1, function 1 enables single-panel panels (1) that are not connected to each other to be made into a compact stack (the state of the stack is also included in the "folded form"), function 3 enables a multi-panel panel (2) formed by connecting single-panel panels (1) to be made into a compact folded form (e.g., Fig. 3(g), Fig. 4(c1)(c2)), and from that state, function 2 enables the multi-panel panel (2) to be used in any bent form (e.g., Figs. 3(a)-(f), Fig. 4(a)(b), Figs. 5-6, Figs. 9-13, Fig. 16, Fig. 19).

The stability of the bent configuration can be evaluated, for example, by the resistance to the moment applied to the joint (JT) of the connecting single-panel panels (1) under the force of Earth's gravity, measured by the following procedure.

(Step 1) For a multi-panel panel (2) in which adjacent single-panel panels (1) are connected at a connecting portion (JT), the angle φ between the adjacent single-panel panels (1) is preferably 30°, more preferably 45°, even more preferably 60°, and even more preferably 90°. With this in mind, connect a string-like body (ST) (which will not stretch or break even when the multi-panel panel (2) is suspended) to the center of gravity of the surface of the end single-panel panel (1), and suspend the multi-panel panel (2) from a horizontal plane (HP) (Figure 19).

(Step 2) If the angle φ between any adjacent single-panel panels (1) does not change for preferably 3 minutes, more preferably 5 minutes, even more preferably 10 minutes, even more preferably 20 minutes, and even more preferably 30 minutes after the multi-panel panel (2) is hung, the connecting part (JT) is deemed to have the ability to maintain its bent shape.

To provide the multi-panel panel (2) with the ability to maintain its bent shape, it is preferable to reduce the weight of the single-panel panel (1) and the multi-panel panel (2) in order to reduce the moment applied to the joint (JT), or to select a joint mechanism with a strong torque resistance that can withstand the moment applied to the joint (JT).

The multi-faceted plate (2) to which the multiple single-faceted plates (1) constituting the present invention 1 are connected preferably further comprises the following function 4 when the single-faceted plates (1) are mirror bodies and the multi-faceted plate is configured as a polygonal mirror (2).
(Function 4) The multi-surface plate (2) made up of connected single-surface plates (1) can be removably attached to the substrate (AH).

For example, conventional tripod mirrors are fixed to a stick-shaped support (Patent Document 1, Figure 1) that is fixed to the wall, or require a dedicated support (Patent Document 2, Figure 2, Nos. 5 and 8) to support the tripod mirror so that it does not fall over. Without such a support, it is difficult to use.

When the present invention 1 is provided with function 4, the multi-surface panel (2) of any curved shape can be removably attached to the substrate (AH) such as a wall, a support, or a desk, so a support is not necessarily required.

Function 4 is to provide an adhesive part (AM) (which can be implemented, for example, by the adhesive mechanism described below) on the surface (SF), edge side (SD), or joint (JT) of the single panel constituting the multi-panel (2), which is removably attached to the adherend (AH), and to fix the multi-panel (2) to the adherend (AH) by adhering the adhesive part (AM) to the surface of the adherend (AH) (for example, Figures 5-1, 5-2, and 18).

The multi-panel (2) to which the multiple single-panel panels (1) constituting the present invention 1 are connected preferably further has the following function 5.

(Function 5) The connected single-panel plates (1) can be twisted (preferably reversibly) at their connected edges relative to each other's surfaces at any rotation angle, and can stably maintain that any rotation angle.

In the present invention 1, function 5 allows any joint (JT) in any curved multi-panel (2) to rotate in a twisted direction relative to the adjacent single-panel (1) (e.g., FIG. 6). For example, when the multi-panel (1) is used as interior decoration, the variety of curved shapes of the multi-panel (2) can be increased. When used as a simple bulletin board, each single-panel (1) can be rotated to display notices on both sides by displaying notices on both sides. In the case of a multi-panel (2), the rotation angle of the single-panel (1) can be adjusted to match multiple subjects located in different locations, allowing the reflected images of multiple subjects to be viewed on a single multi-panel (2).

The connecting parts (JT) of the single panel (1) in the present invention 1 may be installed anywhere on the edge of the single panel (1) and in any number. For example, if the single panel (1) is rectangular, one to four connecting parts (JT) can be installed on the edge parts of the four sides of the single panel (1), so that the single panels (1) can be connected to form a multi-panel panel (2) with various connection configurations (for example, Figures 10(a)(b)(c)).

The single-panel set that can constitute the multi-panel (2) of the present invention 3-1 may include a single-panel that weighs more than 500 g when used under the earth's gravity (preferably the same as the single-panel (1) of the present invention 1 in terms of configuration other than weight) if the multi-panel (2) of the present invention 3-1 has the above-mentioned functions 1 to 3, functions 1 to 4, or functions 1 to 5. As a result, the single-panel that constitutes the multi-panel (2) of the present invention 3-1 may include a single-panel that weighs more than 500 g when used under the earth's gravity (preferably the same as the single-panel (1) of the present invention 1 in terms of configuration other than weight).

[Joint mechanism]
The above functions 1 to 5 can be implemented, for example, by a joint mechanism such as the one exemplified below.

The joint mechanism may be a component independent of the single-panel panel (1) and may be installed on the single-panel panel (1) so as to be removable (for example, via a connecting member such as a screw, adhesive, Velcro, or magnet), or may be incorporated into the connecting portion (JT) of adjacent connected single-panel panels (1) as part of the structure of the single-panel panel (1) (not necessarily in a removable manner, for example, like a hinge that can be inserted and removed).

The joint mechanism is explained below (in the drawings, a four-sided panel consisting of four connected rectangular single-sided panels is used as an example).

(Joint mechanism 1: torque hinge)
A commercially available (e.g., manufactured by Sugatsune Kogyo Co., Ltd.) torque hinge (TH) (a hinge that generates torque due to friction at the hinge shaft and can maintain the angle at any angle φ, also known as a free-stop hinge) is installed on the edge of the single-panel panel (1) to connect the single-panel panel (1) (e.g., Figure 9).

(Joint mechanism 2: universal joint)
The single-panel panels are connected to each other by installing a commercially available plastic universal joint (e.g., made by Mighty Co., Ltd.) at the edge of the single-panel panels. When a universal joint is installed as a connecting part (JT), a bent shape such as that shown in the single-panel panel (1) at the right end of Figure 6 is also possible.

A multi-panel plate (2) consisting of adjacent single-panel plates connected by a universal joint that generates torque due to friction in the rotating part and can maintain the rotation angle at any rotation angle φ can have all of functions 1 to 5.

(Joint mechanism 3: flexible sheet joint)
This is an embodiment of a joint mechanism that connects the single-panel panels (1) with a bendable sheet (SJT) that can be bent, unfolded, and maintain a bent shape, such as a fabric or a soft metal sheet that is resistant to distortion even when made thin and easy to bend, unfold, and/or twist (preferably a metal that is resistant to distortion or soft even when made thin, more preferably a sheet or mesh molded product of tin, lead, or an alloy thereof), which is attached to the connecting edge of the adjacent single-panel panels (1) so that the four-panel panel (2) can be bent and unfolded and maintain a bent shape (for example, Figures 4(a) and (b), Figures 7, 8(a) and (b), Figures 13 and 16).

The bendable sheet (SJT) may be joined across the edges of both single-panel panels (1) along the direction of the connecting edges (e.g., Fig. 4(a), Fig. 16(a)), or may be installed across only a portion of the edges of both single-panel panels (1) along the direction of the connecting edges (e.g., Fig. 4(b), Fig. 6, Fig. 7, Fig. 8(a)(b), Fig. 13, Fig. 16(b)).

(1) Example 1
A peelable sheet is attached across adjacent single-panel panels (1) along the edge of each of the joints (JT) on the side of the joints (JT) to connect them (see, for example, Figure 7).

In Figure 7, for example, a female sheet (SJT♀) of Velcro tape with an adhesive applied to the back side is attached to a single-sided plate (1), and a foldable metal mesh sheet (MMS) (e.g., an aluminum alloy mesh sheet) is inserted between the sheet joint cover (SJTC) and the male sheet (SJT♂), and the male sheet (SJS♂) of Velcro tape is removably attached to the female sheet (SJT♀), so that the female sheet and male sheet of Velcro tape are integrated to form a foldable sheet (SJT).

The adjacent single-panel panels (1) can bend at any angle φ by using the bending function of the male sheet (SJT♂) and maintain that angle (for example, Fig. 7 (a2)). By using the bending shape fixing joint (3) described later in combination, the bending shape can be maintained more stably (for example, Fig. 16).

(2) Example 2
A belt loop (SJTBC) is installed near each connection of adjacent single-panel panels (1) at the connection part (JT), and a belt-shaped flexible belt (SJTB) is inserted into the belt loop (SJTBC) (Figure 8(a) top), and a belt stopper (SJTBS) is fitted into and fixed to the end of the belt-shaped flexible belt (SJTB) (Figure 8(a) bottom), allowing adjacent single-panel panels (1) to be connected in a flexibly manner.

Alternatively, a slit (SJTS) for passing a belt is provided near each of the joints (JT) of adjacent single-panel panels (1) at the joints (JT) (for example, the top of Figure 8 (b)), and a belt-shaped flexible belt (SJTB) is inserted into the slit (SJTS) and fixed by fitting a belt stopper (SJTBS) onto the end of the flexible belt, or the ends of the belt-shaped flexible belt (SJTB) are connected to form a ring-shaped flexible ring (SJTR), and adjacent single-panel panels are connected in a flexible manner (for example, the bottom of Figure 8 (b)).

By connecting the single-panel panels (1) with a bendable sheet (SJT), the polygonal mirror (2) can be easily folded and unfolded (for example, Figure 4 (c)).

The joint mechanism using the bendable sheet (SJT) allows the connected multi-panel panels (2) to maintain any angle φ and form a bent shape, but by using the bent shape fixing joint (3) described below in combination, the bent shape can be maintained more stably (for example, Figure 16 (a) (b)).

When a metal bendable sheet joint (SJT) is installed across the edges of both single-panel panels (1) only partially in the direction of the connecting edges, if the metal material is selected (e.g., tin), it can be twisted and rotated at any angle relative to the surface (SF) of the adjacent single-panel panel, and any angle can be stably maintained (e.g., Figure 6).

(Joint mechanism 4: Rotation-fixed joint)
A hinge (HG) or torque hinge (TH) is installed along the edge direction of the connecting side of adjacent single-panel panels (1) so that it can be inserted and removed from each other, and the hinge (HG) is fixed in the length direction by tightening with a tightening/loosening mechanism (e.g., Fig. 9-1(a)(b)) with screws (SC♂+SC♀) to fix the rotation of the hinge (HG) (e.g., Fig. 9-1(c)), and the mechanism (e.g., a screw) that releases the fixation of the rotation of the hinge (HG) by releasing the tightening of the screws (SC♂+SC♀) can maintain any angle φ between the adjacent single-panel panels (1) (e.g., Fig. 9-2(a)(b)). When a bending form fixing joint (3) described later is used in combination, the bending form can be maintained more stably (e.g., Fig. 16).

(Joint mechanism 5: magnetic joint)
At least the edge portions of the single-panel plates (1) are formed from a magnetic material to connect adjacent single-panel plates (1) (to maintain the bent shape, for example, a part of the connecting portion (JT) is fixed with a bent shape fixing joint (3) described later (for example, FIG. 10(a))).

The magnetic joint allows any edge of a single-panel plate to be connected, improving the freedom of the shape of the multi-panel plate (2) (e.g., Fig. 10 (b) (c)).

(Joint mechanism 6: slide rail joint)
A slide rail joint (for example, 2 in Figure 11) is formed by installing slide rails (SR) on the side surfaces of the edges of the bent portions of adjacent single-panel panels (1), inserting slide hooks (SH) into the slide rails (SR) so that they can move freely along the rails, and further connecting each slide hook (SH) by inserting it into a slide ring rail (SRR) sandwiched between the slide rails (SR) and slide hooks (SH) (the slide hooks (SH) can also move freely along the rails inside the slide ring rail (SRR)) (for example, Figures 11 (a) and (b)).

The slide rail (SR), slide ring rail (SRR) and slide hook (SH) are preferably made of metal or resin, which have good dimensional stability. By using them in combination with the bending shape fixing joint (3) described later, the bending shape can be maintained more stably (for example, Figure 16).

Single-panel panels connected with slide rail joints can bend freely at the joints (JT) (for example, Figure 11 (c)). For example, if the slide hook (SH) is screw-shaped, the bent shape can be maintained by fastening the slide hook (SH) and slide rail (SR) together with a screw.

(Joint mechanism 7: inner string joint)
A groove is made in the surface (SF) or internal surface direction of a single-panel panel through which a string-like material (ST) such as thread, rubber or wire can pass, and the string-like material (ST) passing through the groove connects adjacent single-panel panels, allowing the adjacent single-panel panels to be bent and unfolded (for example, in Figure 12, grooves are arranged in a lattice pattern, and the string-like material (ST) moves along the grooves), and the bent shape can be maintained by using a bending fixture described later (for example, Figure 16).

(Joint mechanism 8: Retractable joint)
(1) Example 1: Joint storage type When the side of one edge of the single-panel panels (1) connected at the edge has a storage space (SP) for the bendable sheet (SJT), and the bent shape is determined (Fig. 13(a)), the sheet joint (SJT) can be stored in the storage space (SP) from the entrance (SPM) of the storage space (SP) for the sheet joint (SJT), and the distance between adjacent single-panel panels (1) (the gap between the connected edges) can be reduced (δ can be minimized) (e.g., Fig. 13(b)). The bent shape can be made more stable by fixing the joint (JT) with a bent shape fixing joint (3) described later (e.g., Fig. 16).

(2) Example 2: Single-panel sliding storage type This is an example of a retractable joint type of single-panel sliding storage type in which a doorway (SPM) and a storage space (SP) through which an adjacent single-panel (1) can be inserted and removed are provided on the side of the joint (JT) of the single-panel (1), and the single-panel (1) can be inserted and removed along a slide rail in the storage space (SP). The edge of the single-panel (1) to be inserted and removed is connected to the doorway (SPM) of the storage space (SP) by a joint mechanism (not shown), and when the single-panel (1) to be inserted and removed is fully exposed from the doorway (SPM) of the storage space (SP), the exposed single-panel (1) can be bent by the joint mechanism (not shown) while maintaining the connection with the doorway (SPM) and the single-panel (1) with the storage space (SP) (for example, FIG. 14 (joint mechanism not shown)).

(Joint mechanism 9: bending shape fixed joint)
(1) Example 1: Bifurcated Clip Joint By clipping across one and/or both widthwise edges of adjacent single-panel panels using the bifurcated clip (CL) of a bifurcated clip joint (CLJT) capable of maintaining any angle φ (e.g., Figs. 15-1(a) and (b)) and 15-2(c) and (d)), the angle φ between adjacent single-panel panels (1) can be maintained, and the bent shape of the multi-panel panel (2) can be maintained. By combining with other joint mechanisms, the stability of maintaining the angle φ of the connected single-panel panels (1) can also be improved (e.g., Figs. 10, 15, 16, and 20).

For example, in the case of the bifurcated clip joints in Figs. 15-1(a)(b) and 15-2(c)(d), two clips (CL) are connected by a bifurcated clip joint (CLJT), which is a hinge (HG) (Figs. 15-1(a)(b) and 15-2(c)) or a torque hinge (TH) (Fig. 15-2(d)) that can be rotated and loosened by a screw or the like, and can open and close at any angle φ in the range of at least 0 to 180° (preferably 0 to 360°) and maintain that angle, so that adjacent single-panel plates (1) clipped to the two clips (CL) of the bifurcated clip joint (CLJT) can also maintain the same angle φ (e.g., Figs. 10, 15, 16, 20).

In the case of Figure 16-1 (a), a slide rail (SR) groove is provided along the upper edge of the single panel (1) so that the bifurcated clip joint (CLJT) can slide along the upper edge of the single panel (1). For example, a slide hook (SH) is provided at the lower end of the clip (CL) in Figures 15-1 (a-4) (b-4) and 15-2 (c)-4, and the slide hook (SH) is fitted into the slide rail (SR) groove so that the bifurcated clip can slide along the slide rail (SR). When fixing the angle φ of the adjacent single panel (1), the bifurcated clip can be slid from the center of the single panel to straddle the connecting part.

In the case of the bifurcated clip joint (CLJT) in Figure 15-2 (c), a hard plate (HP) made of a metal plate or resin, etc., twisted perpendicular to the surface of the clip (CL) is connected to the right end of the left clip (CL), and a hard plate (HP) made of a metal plate or resin, etc., twisted perpendicular to the surface of the clip (CL) is connected to the left end of the right clip (CL). The ends of both hard plates (HP) are overlapped and fixed with a screw-like tightening/loosening mechanism so that the rotational state of both hard plates (HP) can be tightened or loosened (Figure 16-2 (a) shows an embodiment in the case of Figure 15-2 (c)).

When adjacent single-panel panels (1) are clipped with the clip (CL) of the bifurcated clip joint (CLJT) shown in Figure 15-2 (c), if the length of the clip (CL) is preferably 10% or more but less than 100%, more preferably 20-95%, even more preferably 30-90%, even more preferably 40-85%, and even more preferably about 50-80% of the edge of the clipped single-panel panel (1), the clipped single-panel panel (1) can be slid along the length of the clip (CL) to adjust the distance δ between the adjacent single-panel panels (1), and the edges of the adjacent single-panel panels (1) can be brought into contact to make δ nearly 0 (Figures 16-2 (b-1) (b-2) (c)).

In the clip (CL) of the bifurcated clip joint (CLJT) shown in Figure 15-2 (c), if the hard plate (HP) fixed with a screw is positioned at the rear of the clip (CL) as shown in Figure 15-2 (c-3), when the distance δ between adjacent single-panel plates (1) is set to 0, the fastening/loosening mechanism and hard plate (HP) are hidden by the adjacent single-panel plate (1) when viewed from the side (hereinafter referred to as the "front side") other than the side of the multi-panel plate with the fastening/loosening mechanism and hard plate (hereinafter referred to as the "back side"), which is preferable from the viewpoint of the visual aesthetics of the multi-panel plate (preferably a polygonal mirror).

Figure 16-3 shows an example of a four-sided panel (2) formed by connecting four single-sided panels (1) with the clip (CL) of the bifurcated clip joint (CLJT) shown in Figure 15-2 (c). Figures 16-3 (a-1), (a-2), and (a-3) show the front side, and Figures 16-3 (b-1) and (a-2) show the back side.

In Figure 16-3 (a-1), each clip (CL) of the bifurcated clip joint (CLJT) clips to each of the adjacent single-panel panels (1), fixing the four-panel panel (2) in a flat state (φ ≒ 0°) and δ ≒ 0.

In Figure 16-3 (a-2), one of the clips (CL) of the bifurcated clip joint (CLJT) clips both of the adjacent single-panel panels (1), more firmly fixing the flat state (φ ≒ 0°) of the four-panel panel (2).

In Figure 16-3 (a-3), the first and second single-panel panels (1) from the left are clipped to each of the clips (CL) of the bifurcated clip joint (CLJT) and bent (φ>0°), and the distance δ between the second and third single-panel panels (1) from the left is adjusted to be larger, while the third and fourth single-panel panels (1) from the left are in a flat state (φ≒0°) and bent in such a way that they are clipped by one clip.

Figures 16-3 (b-1) and (b-2) show a case where both the upper and lower widthwise edges of adjacent single-panel panels are clipped with a bifurcated clip (CL) of a bifurcated clip joint (CLJT) that can maintain any angle φ, and the clip (CL) that clips the upper edge and the clip (CL) that clips the lower edge are connected by a clip holder (CH) such as a hard plate. By connecting the upper and lower clips with the clip holder (CH), the clip state of the upper and lower clips (CL) becomes stable, improving δ (δ ≒ 0 in Figure 16-3 (b-1), δ > 0 in Figure 16-3 (b-2)) and the stability of the bending form, and further stabilizing the sliding state along the clip (CL).

(2) Example 2: Interlocking Clip A storage space (SP) is provided along the edge of the adjacent sides of adjacent single-panel panels (1), and an interlocking bar (CB) is installed along the edge within the storage space (SP). An interlocking clip (SICL) is fitted across the adjacent interlocking bars (CB) to connect the adjacent single-panel panels (1) (for example, FIG. 17).

The interlocking clip (SICL) is, for example, a cylindrical body split into two halves, with the longitudinal edges of the two split cylindrical bodies (HL) connected by a joint mechanism (preferably a torque hinge) (e.g., Fig. 17(a)). With the interlocking clip (SICL) engaged with the engagement bar (CB) (e.g., Fig. 17(b)(c)), the connecting part (JT) can be maintained at a constant angle φ within a range (e.g., 0 to 180°) to allow the multi-faceted plate (2) to assume a bent shape.

(Joint mechanism 10: connection part shielding joint)
In the joint mechanism, an edge of a single panel adjacent to one of the connected single panels straddles the connection between the first single panel and the adjacent single panel and contacts one surface of the first single panel so that the angle between the first single panel and the adjacent single panel does not exceed a predetermined angle. For example, the case where the single panel (1) of the following embodiment 3 is used will be described (FIG. 21).

The edge portion of the core plate (PLC) of one of the single-panel panels (1) of Example 3, which protrudes from plate 2 (PL2), and the edge portion of the core plate (PLC) of the single-panel panel (1) adjacent to one of the single-panel panels (1) of Example 2, which protrudes from plate 2 (PL2), are connected by a joint (e.g., a bent shape fixing joint (3)) that can assume a bent shape at an angle φ within a predetermined range (Figures 21 (a) and (b)).

When the single-panel plate (1) of Example 3 is used, when the multi-panel plate (2) to which the single-panel plates are connected is expanded to approximately φ=180° (Figure 21 (b)), it is preferable that the distance δ between the edges of the plates 1 (PL1) constituting the adjacent end bodies is small, and δ is preferably 0 to 5 cm, more preferably 0 to 3 cm, even more preferably 0 to 2 cm, even more preferably 0 to 1 cm, even more preferably 0 to 5 mm, even more preferably 0 to 3 mm, even more preferably 0 to 2 mm, even more preferably 0 to 1 mm.

According to the connection shielding joint,
When a single panel (1) of the multi-panel panel (2) is unfolded, an edge portion of plate 1 (PL1) of one of the single panel (1) adjacent to the one single panel comes into contact with the back surface of plate 2 (PL2) of the one single panel (1) of the adjacent connected single panel (1) across the connection portion (part ε in Figure 21 (b) when the single panel (1) of Example 3 is used), preventing the adjacent single panel (1) of the multi-panel panel (2) from unfolding any further.

When the single-panel panel (1) of Example 3 is used, deployment is restricted at φ≒180° (Figure 21(b)).

If the edge of plate 1 (PL1) of the adjacent single-panel plate is bent at an angle γ relative to the surface of plate 1 (PL1) of the single-panel plate, deployment will be restricted at φ ≒ γ.

From the viewpoint of restricting the deployment at a predetermined angle φ, Δ is preferably 1 to 40% of the length of one plate 1 (PL1) of the single-panel panel, more preferably 3 to 30%, even more preferably 5 to 25%, and even more preferably 10 to 20%.

When the single panel (1) of the multi-panel panel (2) of the present invention 3-1 connected by a connecting portion shielding joint is unfolded so that the connecting portion is approximately φ=180, the connecting portion on the plate 1 (PL1) side of the single panel (1) is shielded and the unfolded multi-panel panel (2) appears as a single panel as a whole. Therefore, for example, if the surface on the plate 1 (PL1) side of the single panel (1) of the multi-panel panel (2) is a mirror surface, it functions suitably as a long vertical or horizontal full-length mirror, and if the surface on the plate 2 (PL2) side of the single panel (1) is also a mirror surface, it functions suitably as a full-length mirror with mirror surfaces on both sides (Figure 22-1).

[Adhesion mechanism to adherend]
The multi-panel (2) of the present invention 3-1 can be fixed to the adherend (AH) by providing an adhesive part (AM) on the surface (SF), edge side (SD) or joint (JT) of a single panel constituting the multi-panel (2) that can be removably attached to the surface of the adherend (AH) and adhering the adhesive part (AM) to the surface of the adherend (AH) (for example, Figures 5-1, 5-2 and 18).

(1) Example 1
The adhesive part (AM) can be formed by applying an adhesive to the surface (SE) or the joint (JT) of the single-panel (1) that constitutes the multi-panel (2) or by attaching a double-sided tape such as nanotape (for example, Figures 5-1, 5-2, and 20-2 (c)).

(2) Example 2
A magnetic material (MG) can be provided on the surface (SE) or the joint (JT) of the single-panel plate (1) that constitutes the multi-panel plate (2) to form an adhesive portion (AM) (for example, FIG. 18(a)).

A magnetic sheet with adhesive applied to the back side is pressed and fixed with the adhesive to the part of the adherend (AH) to which the multi-sided plate (2) is to be attached, and the adhesive part of the multi-sided plate is brought into contact with the magnetic sheet and adhered by magnetic force (for example, FIG. 18(a) (magnetic sheet not shown)).

When not being attached to the adherend (AH), the applied adhesive is covered with release paper, and when it is time to attach it to the adherend (AH), the release paper is peeled off and the adhesive is pressed and fixed to the adherend (AH) (for example, Figure 18 (a)).

If the adherend (AH) is magnetic, it may not be necessary to use a magnetic sheet (for example, Figure 18 (a)).

(3) Example 3
Figure 18 (b) shows that the male side (MT♂) of a Velcro tape (MT) can be attached to the surface (SF) or joint (JT) of a single panel (1) that makes up a multi-panel (2) to form an adhesive part (AM).

The female side (MT♀) of the Velcro tape (MT) with adhesive applied to the back side (if the adhesive part is the male side (MT♂)) is pressed and fixed with adhesive to the part of the adherend (AH) where the multi-sided plate (2) is to be attached, and the female Velcro tape (MT♂) of the multi-sided plate (2) is brought into contact with the female Velcro tape (MT♀) and bonded to it (for example, Figure 18 (b)).

When not being pressed and fixed to the adherend (AH), the adhesive applied to the backside of the female side of the Velcro tape (MT) is covered with release paper, and when it is time to press it onto the adherend (AH), the release paper is peeled off and the adhesive is pressed onto the adherend (AH).

(4) Example 4
Suction cups (AD) can be provided on the surfaces or joints of the single panels (1) constituting the multi-panel panel (2) to form adhesive sections (AM) (for example, FIG. 18(c)).

A smooth suction sheet with an adhesive applied to the back surface to which the suction cups (AD) can easily adhere is fixed by pressure with adhesive to the part of the adherend (AH) to which the multi-sided plate (2) is to be attached, and the suction cups (AD) of the multi-sided plate (2) are then pressure-bonded onto the suction sheet (for example, FIG. 18(c) (suction sheet not shown)).

When not being pressed against the adherend (AH), the adhesive applied to the backside of the suction sheet is covered with release paper, and when it is time to press against the adherend (AH), the release paper is peeled off to allow the adhesive to be pressed against the adherend (AH) (for example, Figure 18 (c)).

If the adherend (AH) is made of a smooth material to which the suction cup (AD) can easily adhere, it may not be necessary to use an adsorption sheet (for example, Figure 18 (c)).

[Preferred Use of the Present Invention: Improvement of QOL of Living Environment in Spacecraft]
Inside a spacecraft, astronauts often work alone in small, inorganic living environments.
If the present invention could be removably adhered to adherends such as walls and pillars inside a spacecraft in such a living environment and used for the applications described above, the quality of life (QOL) of the living environment inside the spacecraft would be greatly improved.

In particular, a multi-faceted mirror (2) that can be easily operated and stored compactly on board the spacecraft to help astronauts maintain their appearance is extremely useful when astronauts are talking to each other on board or exchanging information with relevant people on the ground via monitors.

In addition, in a zero-gravity environment, there is no need to consider the weight of the present invention to ensure the functionality of the single-sided plate (preferably a single-sided mirror) (1) or the multi-sided plate (preferably a multi-sided mirror) (2), which allows for a wider range of material options, and the mechanical actions required for functions 1 to 5 of the present invention can be achieved with less force than in a gravity environment, making the present invention more useful in the zero-gravity environment inside a spacecraft.

[The present invention 3-2]
The multi-panel plate (2-2) of the present invention 3-2, which is the present invention 3 formed by connecting a plurality of single-panel plates (1) constituting the present invention 2, has the following functions 1 ₂ to 4 ₂ , and preferably further has the following function 5 ₂ .

(Function 1 ₂ ) The edges of each single panel (1) can be connected and disconnected.

(Function 2 ₂ ) The edge portions of each single-panel plate (1) can be bent at a predetermined angle φ relative to each other.

(Function 3 ₂ ) The connected single panels (1) can be folded and unfolded relative to each other.

(Function ₄₂ ) An edge portion of a single-panel panel adjacent to one of a set of connected single-panel panels straddles the connection portion between the one single-panel panel and the adjacent single-panel panel and contacts one side of the one single-panel panel, so that the angle between the one single-panel panel and the adjacent single-panel panel does not exceed a predetermined angle.

(Function 5 ₂ ) A multi-surface plate (2-2) consisting of connected single-surface plates (1) can be removably attached to an adherend (AH).

Invention 3-2 also includes aspects in which "the connected single-panel plates cannot bend at the edge portions while maintaining a predetermined or arbitrary angle φ relative to each other," so for example, in the [joint mechanism] of invention 1, this includes aspects in which torque is not generated at the rotating shaft, the rotating shaft is not fastened with screws or the like, and the entire polyhedron (2-2) must be supported by an external support mechanism such as a hand in order to maintain the angle φ and maintain the bent shape.

In present invention 3-2, except for the case where the angle φ is maintained and the bent shape cannot be maintained, the preferred embodiments for achieving functions 1 ₂ to 3 ₂ in present invention 3-1 are applicable to the preferred embodiments for achieving functions 1 ₂ to 3 ₂ .

In present invention 3-2, in order to achieve function _4-2 , the connection portion shielding joint of joint mechanism 10 in present invention 3-1 may be a joint mechanism that cannot maintain a bent shape, rather than a joint that is fixed to a bent shape as in embodiments 1 and 2.

In the present invention 3-2, the bent shape cannot be maintained,
In the case where the multi-panel (2-2) is deployed to a predetermined angle under the gravity of the earth and the entire multi-panel (2-2) is used as a full-length mirror, it is preferable that the multi-panel (2-2) be removably attached to the substrate (AH) in that state.
In a zero-gravity space, when the multi-panel (2-2) is deployed to a predetermined angle and the entire multi-panel (2-2) is used as a full-length mirror, it is preferable that the multi-panel (2-2) be removably attached to the substrate (AH) at multiple points so that the deployed state can be maintained.

In invention 3-2, except for the case where the angle φ is maintained and the bent shape cannot be maintained, the preferred embodiment for achieving function _5-2 is the same as the preferred embodiment for achieving function 5 in invention 3-1.

Example 1
An embodiment in which a four-sided mirror (2) is formed by connecting a single-sided plate, which is the single mirror (1) of the present invention 3-1, with a bent shape fixed joint will be described with reference to Figs. 20-1 to 20-3.

〔material〕
(1) Single-sided mirror (1) (Figure 20-1): "Alpolic RF PE" manufactured by Mitsubishi Chemical Infratec Co., Ltd. (a metal sandwich structure with anodized aluminum mirror surface and polyethylene core)
(1-1) Width: 150mm (1-2) Length: 210mm (1-3) Thickness: 2mm (1-4) Weight: 120g
(1-5) Ratio (width/length): 100/140 (1-6) Area: 315 ^cm2

(2) Joint mechanism (3) (Fig. 20-3, Fig. 20-4): This is the bending shape fixed joint example 1 (Fig. 15-2(c)) and the torque hinge (Fig. 15-2(d)) type, both of which were created by the inventor.

The tetrahedron in the embodiment is bent by connecting a single mirror (1) with only fixed joints:
φ＞0° (Fig. 20-1(a)(b), Fig. 20-4(a)(b));
φ ≈ 180° (Figure 20-1 (c));
φ≒0° (Figure 20-3 (c))
is fixed.

(3) Folding storage device (FS): A flame-retardant fabric (carbon sheet (SG-250, Osaka Tamashii Co., Ltd.)) is attached to the back of a single-panel panel with flame-retardant double-sided tape (No. 5011N, Nitto Denko Corporation) to integrate it with a multi-panel panel, and the mirror can be folded, wrapped, and carried.

In the example tetrahedron, the bend form locking joint can slide along the top edge of the single plate;
When fixing the bent shape, the bifurcated clip (CL) is slid to a position spanning two adjacent single-panel panels (1) to form and fix the bent shape of the two adjacent single-panel panels (1) (Figure 20-1 (a) (b)).
When releasing the bent shape or disconnecting the single-panel panels, the bifurcated clip (CL) is slid and moved onto one of the single-panel panels (1) so that it does not straddle the two single-panel panels (1) (not shown in the figure).

[Four-sided mirror (2)]
Since the joint mechanism (3) is installed on the single-sided mirror (1), the width, length and thickness of the folded mirror are slightly larger than those of the single-sided mirror (1), and the weight is slightly larger than the total weight of the single-sided mirror (1).

(1) Dimensions and weight when flat (the bending angle of the adjacent single-sided mirror (1) is ≒ 0°)
(1-1) Width: 155mm (1-2) Length: 210mm (1-3) Thickness: 6mm (1-4) Weight: 750g

(2) Thickness when folded: 2.5 cm

(3) Bending form (3-1) Concave bending (Fig. 3(d)) (Fig. 20-1(a))
(3-2) When bent into a W shape (Fig. 3(e)) (Fig. 20-1(b))
(3-3) When placed in a flat state (Fig. 3(f)) (Fig. 20-1(c))
(3-4) When the adjacent single mirror is folded (Fig. 3(g)) (Fig. 20-3(c))

When the four-sided mirror (2) in the embodiment is flattened, the distance δ between the adjacent single-sided mirror (1) becomes almost 0 (Fig. 20-1 (a) (b) (c), Fig. 20-2 (a-1) (a-2) (b-2), Fig. 20-3 (b))

Figure 20-1 (a) and (b) show a user holding a four-sided mirror (2) with both hands outstretched.

(4) Adhesion mode (4-1): The four-sided mirror (2) of the embodiment is bent, and the back surface of the second single-sided mirror (1) from the left is adhered horizontally to the wall (AH) of the adherend (FIG. 20-2 (a-1) (a-2)).
(4-2) The four-sided mirror (2) of the embodiment is bent, and the back surface of the second single-sided mirror (1) from the left is attached vertically to the wall (AH) of the adherend (Figure 20-2 (b)).
(4-3) The four-sided mirror (2) of the embodiment is laid flat, and the back surface of the top single-sided mirror (1) is adhered vertically to the wall (AH) of the substrate (Figure 20-1 (c)).

(4-4) Figure 20-2 (c) shows the adhesive part in which a male Velcro tape (MT♂) is attached with adhesive to the back surface of the top single-sided mirror (1) in Figure 20-1 (c) and a female Velcro tape (MT♀) is attached with adhesive to the wall (AH) of the adherend in Figure 20-1 (c) (the mechanism is the same as in Figure 18 (b)).
(4-5) In Figure 20-2 (a-1) (a-2) (b), the adhesive part on the back side of the second single-sided mirror (1) from the left and the wall of the substrate (AH) also have a similar mechanism.

Figure 20-2 (b) shows a four-sided mirror (2) attached vertically to the wall (AH) of the substrate, with the user using it to see his or her own frontal image.

(5) Joint Mechanism The bent form fixed joint (3), which is the joint mechanism that constitutes the connection part of the adjacent single-panel plates (1) of the tetrahedron (2) of the embodiment, is shown in Figure 20-3.

The connecting portion shown in Figure 20-3 consists of two clips (CL) connected by a bifurcated clip joint (CLJT), which is a hinge that can be tightened and loosened by a screw and can be opened and closed at any angle φ in the range of at least 0 to 180° (preferably 0 to 360°) and can maintain that angle, so that adjacent single-panel panels fixed by two clips (CL) connected to the bifurcated clip joint (CLJT) can also maintain the same angle φ (Figure 20-3 (a-1) (a-2) φ>0°, (b) φ≒180°, (c) φ≒0°).

In Fig. 20-4, a folding storage device (FS) is placed on one of the single panels (1) of the multi-panel panel (2) (preferably the terminalmost single panel (1)) so that the folded multi-panel panel (2) can be folded and stored in the folding storage device, improving portability (for example, Fig. 20-4). In this case, providing a handle for carrying the folding storage device will further improve portability.

Example 2
An embodiment in which a four-sided mirror (2-2) is formed by connecting a single-sided plate, which is the single mirror (1) of the present invention 3-2, with a connecting portion shielding joint will be described with reference to Figs. 21 and 22.

〔material〕
(1) Plate 1 (PL1): PET film aluminum vapor deposition mirror, manufactured by Horiuchi Mirror Co., Ltd. The front surface is mirror-like and the back surface is polystyrene resin.
(2) Plate 2 (PL2): PET film aluminum vapor deposition mirror, manufactured by Horiuchi Mirror Co., Ltd. The front surface is mirror-like and the back surface is polystyrene resin.
(3) Core plate (1c): Chipboard, manufactured by Nippon Paper Industries Co., Ltd. (4) Adhesive: Super transparent bond, manufactured by Shinto Sangyo Co., Ltd. (5) Adhesive tape: Aluminum glass cloth tape, manufactured by Nitto Co., Ltd. (6) Magic tape: manufactured by Nomex Co., Ltd.

[Single-sided panel (1)]
Four single-sided plates (1) 1a, 1b, 1c and 1d of Example 3 were produced by bonding one side of a rectangular core plate (PLC) to the back side of plate 1 (PL1) and the other side to the back side of plate 2 (PL2) with an adhesive.
When the plates are laminated together, both end edges of the core plate (PLC) extending in the width direction protrude beyond at least one end edge of the plate 2 (PL2) extending in the width direction, so that the core plate (PLC) covers the plate 2 (PL2);
Plate 1 (PL1) and plate 2 (PL2) have their widthwise extending edges offset by a distance Δ in the lengthwise direction (for example, the shape shown in the front view (a2), plan view (b2), and right side view (c2) of FIG. 1-2).

[Four-sided mirror (2)]
Adjacent single-panel panels (1) were fixed to the edges of the core plate (PLC) with tape (in FIG. 21, the bent shape fixing joint (3) was replaced with adhesive tape) to produce a four-sided mirror (2).

The dimensions and weight of the four-sided mirror (2) and its components are shown in Table 1.

Female Velcro (MT♀) was placed on the surface of plate 2 (PL2) of the single-sided plate (1) at both ends of the four-sided mirror (2) (Figure 22 (a)).

In Example 2, the functional description in FIG. 21 is applicable, except that the connected single-panel panels (1) cannot bend at their edges while maintaining a predetermined or arbitrary angle φ with respect to each other.

[Example of how to use the four-sided mirror (2)]
(1) To use it as a full-length mirror, the four-sided mirror (2) was unfolded so that φ ≒ 180°, and the female side Velcro tape (MT♀) of the four-sided mirror (2) was attached to the male side Velcro tape (♂) installed on the wall to secure it in place (Figure 22(b)).

Under Earth's gravity, when the four-sided mirror (2) is deployed vertically, the plate 1 (PL1) side will be at an angle of φ ≒ 180° due to its own weight, and adjacent plates 1 (PL1) will come into direct contact (shielding the connection parts) to form a full-length mirror (Fig. 21(b), Fig. 22(b)). However, in a weightless environment such as inside a manned space rocket, it is preferable to leave the four-sided mirror (2) deployed at φ ≒ 180° as in Example 2 and to fasten the single-sided mirrors (1) at both ends to a substrate (AH) such as a wall.

(2) Under Earth gravity, if the longitudinal edge of the four-sided mirror (2) is placed on the surface of a desk, it can be used as a four-sided mirror (2) at an angle of 0 < φ < 180°. Even in zero gravity, if the longitudinal edge of the four-sided mirror (2-2) is fixed to the surface of the substrate (AH), it can be used as a four-sided mirror (2) at an angle of 0 < φ < 180° (Figure 22 (c)).
