Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves provided on an upper edge of an opening such as a window or a doorway provided on a wall surface of a building, and the eaves plate is made of a rigid plate, and as required. The present invention relates to an eaves that also serves as a shielding panel that can be used as a shielding panel for shutters, shutters, etc. that cover the opening.

[0002]

2. Description of the Related Art The structure conventionally proposed as a shield panel combined eaves is as follows. In the first structure, guide rails for the shutter are provided on both sides of the window, and the guide rail is bent at an acute angle so as to project outward at the upper end of the opening of the window, and the shutter guided by the guide rail is opened. When the shutter plate is moved upward, the shutter plate is guided by the bending portion of the guide rail and extends outward to form an eaves plate (for example, JP-A-63-201290).

As a second structure using a shutter plate whose both end edges are slidably supported by guide rails similar to the above, a shutter plate winding mechanism is provided at the upper edge of the window and a predetermined upper portion of the guide rail is provided. The length of the shutter plate is a swing rail that can swing outward with the upper end as a fulcrum, and the shutter plate is rolled up to a position where the lower part of the shutter plate fits into this swing rail, and then the swing rail is swung outward, thereby This is a structure in which an eaves plate is formed in the lower part (Japanese Utility Model Laid-Open No. 60-143891).

As a third structure using a shutter plate, an eaves plate having a certain vertical width is connected to the lower edge of the shutter plate to be wound up so as to be swingable about a horizontal axis, and the shutter plate is placed above a window. There is a structure in which this eaves plate is guided so as to stand up toward the outside when it is wound up to the edge (Japanese Utility Model Publication No. 58-83593).

As a fourth structure, there is a structure in which a shutter door plate is vertically folded in a zigzag shape like a folding screen to form an eaves. In such a structure, guide rails are provided on both sides of the window, and the lower end of the shutter door plate or the both ends of the valley fold portion that is folded in a folding screen is guided by the guide rails. The upper edge of the shutter board is pivotally attached to the upper edge of the window. By lifting the lower end of the shutter door plate, the shutter door plate is folded in a zigzag shape to form an eaves in a state of being superposed on the upper portion of the window (for example, Japanese Utility Model Laid-Open No. 57-21785).

All of the above structures require a guide rail on the side edge of the window, but as a fifth structure in which such a guide rail is unnecessary, the shutter door plate is divided into upper and lower parts and the upper edge of the upper shutter door plate is used. And the lower edge of the lower shutter plate are pivotally attached to the windows along the upper and lower edges of the window so as to be swingable about a horizontal axis, and the upper shutter plate is rotated upward to form an eaves. There is a structure in which it is rotated downward and supported in a horizontal state by a separately provided supporting member to be used as a wetting edge (for example, Japanese Utility Model Laid-Open No. 56-67292).

[0007]

In the structure using the shutter plate, an accommodating portion for accommodating the rolled-up shutter plate is required, and since this accommodating portion projects above the upper edge of the window, the structure is constructed. Spoil the look of. In addition, the structure in which the shutter plate extends outward along the guide rail makes the eaves unnecessarily long, and when the shutter is closed (when used as a shutter), only the guide rail protrudes outward. Then, it's really ugly.

Further, a zigzag-folded article has an unusually thick eaves when it is folded and formed into an eaves, which is unattractive. This is because the outer surface and the inner surface are folded so that they face each other when used as a shutter when folded, so, for example, when bars are provided to give rigidity to the plate, the bars are overlapped and folded. This is because it will thicken.

Further, the structure requiring the guide rails on the side edges is unattractive when the shutter is opened. As a common drawback of the structure with the guide rail, there is no effective means to prevent the guide surface of the guide rail from being exposed to wind and rain, so it is easy for rust to occur in a short period of time and smooth opening and closing operation due to rust. Can be significantly impaired.

Further, the structure in which the shutter door plate is divided into upper and lower parts and used as the eaves plate and the wet edge, respectively, has an advantage that the structure is simple and a guide rail is not required, but an opening through which the wet edge can be projected. Due to the limited number of parts and the large design constraints, it can only be applied to some limited buildings or openings.

In view of these problems of the conventional structure, the present invention has an appearance and durability, has a large degree of freedom in design, and thus has an eaves-covering panel that can be applied to a wider opening. It is an issue.

[0012]

SUMMARY OF THE INVENTION A shield panel combined eaves of the present invention has a base end 11 rotatably supporting a base end 11 about an axis parallel to the upper edge of an opening 9 provided in a wall surface of a building. Eaves board 1
The expansion and contraction mechanisms 4 and 6 parallel to the base end eaves plate and in the direction orthogonal to the axis are attached to the expansion and contraction end 45 of the expansion and contraction mechanism.
The base end sides of the tip side eaves plates 7 and 8 are connected to 46, 63 and 64, respectively.

A pantograph mechanism 4 and a screw mechanism 6 can be used as the expansion / contraction mechanism. Is it possible to guide the expansion / contraction of the tip side eaves plates 7 and 8 by providing two sets of these mechanisms 4 and 6 and synchronously driving them? Alternatively, in addition to these expansion and contraction mechanisms, a slide guide mechanism for guiding the tip side eaves plate is provided. When the extension mechanism is a screw mechanism, the tip side eaves plates 7 and 8 are connected to the nut members 63 and 64 screwed to the screw rods 61 and 62, and the screw rods 61 and 62 are connected to the base end of the base end cover plate 1. It is rotationally driven from a rotary drive shaft 5 mounted in a direction parallel to the side 11 via a bevel gear pair 51, 52.

When the pantograph mechanism 4 is used as the expansion / contraction mechanism, the base end side eaves plates 7 and 8 are connected to the pins 45, 46 or 47 pivotally connecting the links of the pantograph mechanism to each other to form the pantograph mechanism. The nut member 38 is attached to at least one of the base ends 41 of the base end side of the base member 41, and the nut member 38 is mounted on the rotating drive screw rod 3 mounted in parallel with the base end side 11 of the base end cover 1. Drive by screwing.

The tip side eaves plates 7 and 8 are provided so as to be located closer to the elastic members 4 and 6 than the plate surface of the base end side eaves plate 1 in the thickness direction of the eaves plate. The tip side eaves plate may be one piece or two or more pieces, and when it is two or more pieces, the elastic member 4,
The telescopic ends 45, 46, 63, 64 of 6 are provided in multiple stages, and two or more tip side eaves plates 7, 8 are connected to each of them.

[0016]

The eaves are formed in the upper part of the opening by retracting the expansion and contraction mechanisms 4 and 6 and rotating the base end eaves plate 1 outward. At this time, the tip-side eaves plates 7 and 8 are housed in such a manner that they are superposed along the lower surface of the base-end eaves plate 1. From this state, the base eaves plate 1 is rotated downward so that the eaves surface is in the vertical direction, and the extension and contraction mechanisms 4 and 6 are extended so that the tip side eaves plates 7 and 8 are separated from the tip end side of the base end eaves plate 1. It is paid out and extends downward. Then, the extension of the elastic members 4, 6 is stopped in a state in which the base end sides of the tip side eaves plates 8 and 7 are slightly overlapped with the tip end side of the tip side eaves plate 7 or the base end eaves plate 1 located thereabove. In this state, the tip side eaves plates 7 and 8 extend to a length that covers the vertical dimension of the opening and shield the entire opening.

When the elastic members 4, 6 are expanded and contracted from this state, the elastic ends 45, 46, 47, 63, 64 move toward the proximal end side of the proximal eaves plate 1, and the elastic ends 45, 46. ,
Tip side eaves plates 7, 8 in which base end sides are connected to 47, 63, 64
Are drawn into the inside of the base eaves plate 1. Then, the eaves are formed at the upper edge of the opening by rotating the base end eaves plate 1 outward after the front end side eaves plates 7 and 8 are pulled in.

The number of steps of the tip side eaves plates 7 and 8 is determined by the relationship between the size of the eaves and the vertical size of the opening. When the vertical dimension of the opening is larger than the overhanging dimension of the eaves, the number of tip eaves plates must be increased, but the length of the eaves is designed to be long so that the number of tip eaves plates is reduced. Is preferred.

[0019]

1 to 6 show a first embodiment of the present invention. In the first embodiment, a pantograph mechanism is used as the expansion / contraction mechanism. A cylindrical body 12 is fixed to a base end side 11 of the proximal end eaves plate 1.
Both ends of 2 are rotatably supported by the eaves frame 2 shown in FIG. An internal gear 13 shown in FIGS. 4 and 5 is provided at one end of the cylindrical body 12, and a reduction motor 22 having a pinion 21 meshing with the internal gear 13 fixed to an output shaft is fixed to one end of the eave frame 2. This reduction motor 22
The cylindrical body 12 is rotated by the rotation of, and the base end eaves plate 1 is tilted around the axis of the cylindrical body 12.

A screw rod 3 is rotatably mounted on the shaft center of the cylindrical body 12, and a motor 23 for rotating the screw rod is fixed to the eave frame 2. The threaded rod 3 has a large diameter portion 31 in the central portion, and screws 33, 34, 35 having equal leads are provided on both sides of the large diameter portion and on the portions adjacent to the large diameter portions of the small diameter portions 32 on both sides. 36 are provided.
These screws 33, 34, 35, 36 are opposite in screw direction to adjacent screws. That is, if the small-diameter screw 33 on the left side of the drawing is a right-hand screw, the left-hand screw 34 of the large-diameter part is a left-hand screw, the right-hand screw 35 of the large-diameter part is a right-hand screw, and the small-diameter screw 36 on the right is a left-hand screw. It is a screw. These screws 33, 3
Nut joints 37 and 38 connected to a link 41 at the base end of the pantograph mechanism 4 are screwed into 4, 35 and 36, respectively.

Two pantograph mechanisms 4 are provided, and these two pantograph mechanisms are moved forward and backward synchronously so that the tip side eaves plates 7 and 8 move forward and backward in parallel. Each pantograph mechanism 4 is composed of a total of six links, three on one side, and the base end links 41 and the intermediate links 42 are fulcrum pins 44, respectively.
45 is pivoted in an X shape, and the tip links 43 are pivotally connected in a V shape by pivot pins 46 at the tips. The base end of the base end link 41 is pivotally connected to the screw joints 37 and 38, the base end of the intermediate link 42 is pivotally connected to the tip of the base end link 41, and the tip end of the tip link 43 is connected to the end of the intermediate link 42. The proximal ends are pivotally connected.

The fulcrum pins 45 of the intermediate link of the two pantograph mechanisms 4 are connected to each other by a strip plate 71 (see FIG. 6) in a direction parallel to the screw rod 3, and the strip plate 71 has an intermediate eaves plate. The base end side of 7 is fixed. That is, in FIG. 6, the fulcrum pin 45 pivotally connecting the intermediate links 42, 42 has a short cylindrical shape and is provided with an integral flange 45a at one end, and extends on the opposite side of the flange 45a in the direction perpendicular to the paper surface of FIG. The strip plate 71 is fixed by screws 72 to sandwich the pair of intermediate links 42, 42 in a direction perpendicular to the plane, and the intermediate eaves plate 7 is fixed to the strip plate 71.

The connecting pin 47 connecting the base link and the intermediate link and the intermediate link and the tip link is provided with a shoe 48 as shown in FIG. 6, and the shoe 48 is used for the base eave plate 1 and the intermediate eave plate. It is slidably in contact with the back surface of 7. Also in the connecting pin 47 portion, the links 42 and 43 that are connected to each other are connected to each other by the collar 47a and the shoe 4
The structure is sandwiched by 8 and. With such a structure, the pantograph mechanism can be made thinner without lowering the bending rigidity at the linking portion of the link of the pantograph mechanism, and the bending force in the vertical direction acting on the pantograph mechanism can be reduced. Can be dispersed to increase the rigidity and strength of the eaves that also serve as the shielding panel.

Like the fulcrum pin 45 of the intermediate link, the pivot pins 46 of the tip link are also connected to each other by a strip plate 81 similar to the strip plate 71 shown in FIG. 6, and the strip eave plate 8 is attached to the strip plate 81. The base edge of is fixed.

The base end link 41 and the intermediate link 42 of the pantograph mechanism 4 do not always have the same length. Further, the fulcrum pins 44 and 45 that pivotally support the proximal links and the intermediate links do not have to be located at the center of the length of each link. In the structure shown in the figure, the longer the intermediate link 42 is than the base end link 41, the larger the advance stroke of the tip side eaves plates 7 and 8 can be taken. In addition, it is common to change the link length in this way to make the link fit more compact when the link is degenerated.

In the illustrated embodiment, the two base end links 41 of each pantograph mechanism are connected to the nut joints 37 and 38 together.
The pantograph mechanism is expanded and contracted by the movement of the nut joint symmetrical to the center line of each pantograph mechanism, but it is also possible to use a one-side driven pantograph mechanism. That is, the outer base ends of both pantograph mechanisms are pivotally attached to the base end side of the base end cover 1 at a fixed position, and only the inner base link is driven by the screw rod 3. In the case of such a configuration, the fulcrum pins 44 and 45 described in the embodiment of the drawing draw a curved locus, and the one outside the connecting pin 47 advances and retreats in a rectilinear motion. It is rational that the tip eaves plates 7 and 8 are connected to the outer connecting pins.

Further, in the illustrated embodiment, two pantograph mechanisms 4 and 4 are used to expand and contract the tip side eaves plates 7 and 8 in parallel and to prevent blurring in the left and right directions. However, one pantograph mechanism is used. It is also possible to adopt a structure in which the guide member provided separately guides the direction of the tip side eaves plates 7 and 8 and the blur.

Each of the eaves plates 1, 7, and 8 may have a structure in which the plate surface is formed only on the outer surface and the inside is opened, or the eave plate may have a box structure. In the embodiment shown in the drawing, both side edges of the plate material forming the outer side surface are bent inward so that a gap seen from the side does not occur when the plate material is used as a shutter. Therefore, the shape of the front surface when used as a shutter is not necessarily the shape, although the width of the tip side eaves plate is narrowed by the plate thickness. That is, in the structure of the present invention, it is not always necessary to guide the side edge of the eaves plate, so that the side edge of the eaves plate can be designed in a free shape including a curved line.

7 and 8 are views showing a second embodiment of the present invention. The second embodiment uses a two-stage screw mechanism as a telescopic mechanism. In the second embodiment, the rotary shaft 5 is mounted at the position of the screw rod 3 of the first embodiment, and the base ball screw 61 and the tip ball screw 62 of the screw mechanism 6 provided on the rotary shaft 2 are installed. Two bevel gear pairs 51 and 52 to be driven are provided, each pair being 4 pairs. A base end of the base ball screw 61 is axially supported by the base end cover 1 by a bearing (not shown), and is rotationally driven by the rotating shaft 5 via the bevel gear pair 51. A proximal nut member 63 is screwed onto the proximal ball screw, and the proximal nut member 63 is fixed to the proximal side of the intermediate eaves plate 7.

A base end of a slide key shaft 53 is pivotally supported on the base eave plate 1 in parallel with the base ball screw 61. The slide key shaft 53 is rotatable with respect to the base nut member 63 and is not axially movable. The sliding gear 54 axially mounted on the shaft penetrates through the sliding gear 54 so as not to be relatively rotatable and axially movable. Also, this base end nut member 63
A base end of a tip ball screw 62 is rotatably supported, and a driven gear 55 fixed to the base end meshes with the sliding gear 54. The sliding key shaft 53 is rotationally driven by the rotating shaft 5 via the bevel gear pair 52, and the rotation of the sliding key shaft 53 rotates the tip ball screw 62 via the sliding gear 54 and the driven gear 55. The base end side of the tip eaves plate 8 is fixed to the tip nut member 64 screwed to the tip ball screw 62.

In the above structure, when the rotary shaft 5 is driven to rotate, the base ball screw 61 rotates to move the base nut member 61 screwed into the base ball screw 61 forward and backward, and the intermediate eaves plate 7 connected to the base nut member 61 forward and backward. At the same time, the sliding key shaft 53 rotates, and the forward / backward movement of the proximal end nut member 63 is absorbed by the axial movement between the sliding gear 54 and the sliding key shaft 53, and the rotation of the sliding key shaft 53 causes the gear pair 54, 55 to rotate. The tip ball screw 62 is rotated via the tip nut member 64 by this rotation.
The tip eaves plate 8 moves back and forth by moving back and forth.

In the second embodiment as well, as in the first embodiment, the eaves are formed by rotating the cylindrical body 12 outward with the tip side eaves plates 7 and 8 retracted, and the base end. By extending the tip-side eaves plates 7 and 8 with the eaves plate facing downward, a shutter for covering windows and doorways is formed. In the illustrated second embodiment, a two-stage ball screw is used, but when the expansion / contraction stroke is small, such as when the height of the window is small, the ball screw can be one stage, and the structure can be greatly simplified. .

[0033]

According to the present invention described above, since the elongating and contracting mechanism of the eaves plate is mounted inside the eaves plate, the eaves plate is not exposed to wind and rain and is excellent in durability. Further, since it is not necessary to provide a rail on the side edge of the opening, and the shape of the eaves board can be designed more freely, it is possible to obtain a shielding panel / eave that has a better appearance and matches the design of the entire building. Further, it can be attached to an opening where a wet edge or the like cannot be provided, and the eaves length does not become excessively long even if the vertical dimension of the opening is large, and the aesthetic appearance of the entire building can be improved.
