DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sunshade mounted on an outer wall of a building or the like.

[0002]

2. Description of the Related Art Conventionally, a awning attached to an outer wall of a building or the like is generally constructed by connecting a plurality of strip-shaped flat plates as shown in Japanese Utility Model Publication No. 4-9791 and attaching the connected flat plate to the outer wall of the building. The support arm was attached to the other flat plate.

[0003]

However, in such a case,
Since each panel of the sunshade is a flat plate, the support arm must be expanded and contracted appropriately when the panel is pulled out of the building or stored on the outer wall side, which requires skill in operation, and furthermore, the entire panel The heavier the weight, the more rigid and complicated the expansion and contraction mechanism was required.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate such a problem. One end of the uppermost panel is supported on an outer wall, and the second and subsequent panels are provided on both sides of the panel immediately above. An arm having a plurality of connecting members that slide in the guide provided in the lower arm, the distal end of the support arm is movably mounted in the guide of the lowermost panel, and the base end is provided below the outer wall. In a sunshade pivotally supported by a bracket, the support arm has a fixed length, and each panel has an arcuate curved surface shape that can follow the rotation of the tip of the support arm. As a result, it is possible to smoothly pull out the second and subsequent panels to the outside of the building and store them on the outer wall side without the need to extend and retract the support arm. In addition, when each panel is pulled out of the building, it becomes a curved panel sunshade. Therefore, even if there is an obstacle below the sunshade panel, the obstacle is easily obstructed compared to the conventional straight drawer panel. Things can be avoided (FIG. 8).

[0005] This embodiment will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state in which a sunshade panel (hereinafter, abbreviated as a panel as appropriate) according to the present invention is drawn out, and a panel 2 is composed of three sheets, and 2a and 2a.
Panels b and 2c are the uppermost, middle, and lowermost panels, respectively. One end of the uppermost panel 2a is supported by a panel bracket 20 previously attached to an outer wall 40 of a building or the like.
Reference numerals 10 and 10 denote support arms for supporting the entire panel. The support arms are mounted so that their distal ends can move within guides provided on both side ends of the lowermost panel 2c, and their base ends are connected to the outer wall 40.

A roller bearing 52 that slides inside is pivotally mounted, and a lower part is provided with a support member 53 for coupling with the upper part of the side cover 7 of the panel 2 immediately below. The connecting tool 50 of the lowermost panel 2 c forms the distal end of the support arm 10.

Reference numeral 60 denotes a pulley, which guides an operation string 100 for rotating the support arm 10. The pulley 60 is pivotally supported on a support side 65 fixed to the inner wall of the upper chamber P and the skirt portion S.

FIGS. 5 and 6 show each panel 2a, 2b,
FIG. 5 is a detailed side cross-sectional view of FIG.
a, 2b, and 2c are stored in the outer wall 40, and FIG. 6 shows a state in which the middle panel 2b and the lowermost panel 2c are drawn out of the outer wall 40.

In FIGS. 5 and 6, reference numerals 8, 8... Denote blocks provided at both ends of the side covers 7, 7 of each panel.
The roller bearing 52 is prevented from coming out of the guide R. Therefore, the roller bearing 52 slides between the two blocks 8, 8 of the curved guide. Operation string 10
No. 0, one end is attached to the support shaft 51 of the support arm 10, and the pulleys 60, 60... Mounted on the support shaft 51 at the intermediate portion in the upper chamber P of the side covers 7, 7. The other end is locked by the locking tool 110.

In the present embodiment, the support arm 10 is made of a single unitary member which does not require expansion and contraction adjustment. The cross section of the side cover 7 including the panels 2a, 2b, 2c and the guide R is formed by a support arm 10 that rotates about a pivot point of the arm bracket 30.
Has a circular arc shape that can follow the movement of the tip (roller bearing 52). That is, the curvature of the panel 2 is determined by determining the length of the support arm 10 in advance. On the other hand, the curvatures of the panel 2 and the side cover 7 may be determined first, and the support arm 10 having a length having a movement locus corresponding to the curvature may be prepared. Note that a support arm provided with a telescopic adjustment mechanism may be fixed and used at a predetermined length.

The operation of the present invention configured as described above will be described below. FIG. 7A shows a state in which the panel 2 is pulled back to the outer wall 40, that is, stored in the outer wall 40 in a superposed state. At this time, the operation string 100 is
What is necessary is just to unwind from 0, make it loose, and wind it on the locking tool 110 again. This is because the restraining elastic device 200 acts so that the support arm 10 always stands on the outer wall 40. Therefore, the roller bearing at the tip end of the support arm 10 is provided on the block 8 side of the outer wall side guide end of the lowermost panel 2c. 5
This is because the lowermost panel 2c and the middle panel 2b can be sequentially moved to the outer wall side in combination with the loosening of the operation string 100, resulting in a superposed state.

FIG. 7B shows a state in which the lowermost panel 2 c is first drawn out of the outer wall 40. By pulling the operating cord 100 below the outer wall 40 against the urging force of the restraining elastic device 200, the roller bearing 52 at the tip of the support arm 10 moves to the outer block 8 of the lowermost panel 2c (FIG. 5 arrow), and further pulling the operation string 100, the connecting tool 50 of the lowermost panel 2c
Can be moved to the outer block 8 of the guide of the middle panel 2b. If the operation string 100 is wound around the lock 110 at this position, a half-open awning can be obtained.

FIG. 7C shows a state where each panel is completely drawn out. By further pulling the operation string 100 from the state of FIG. 7B, the connecting tool 50 of the middle panel 2b can be moved to the outer block 8 of the guide of the top panel 2a.

When the panel 2 is completely pulled out, an undrawn portion (X in FIG. 6) is provided between the panels. This is to further enhance the light shielding effect.

In short, the present invention relates to each panel 2a, 2
b, 2c, and the guide R are formed in a curved surface of an arc shape along the rotation locus of the distal end of the support arm 10, so that the single support arm 10 provides two steps in the rotational locus of the distal end. Since each of the panels 2b and 2c following the eye can perform the pull-out and pull-back operations, the opening / closing operation becomes extremely light, and further, the following operational effects are obtained.

Since the restraining elastic member 200 is interposed at the base end portion 11 of the support arm 10, the support arm 10 is always maintained upright on the outer wall 40, and the panel is pulled out except when necessary. There is no. Therefore, when the panel is lightweight, the storage of the panel can be performed with one touch. Since each panel 2 is hollow, the total weight of the panel can be reduced, so that the support arm 1
0 can also be a correspondingly lightweight member. Since the screw holes 6 are integrally formed on both side surfaces of each panel 2, the screw holes 6 can be easily assembled to the panel 2 without separately receiving the side covers 7. Since the skirt portion S is provided in the lower chamber Q of the side cover 7, the operation string 100 is not exposed, and the aesthetic appearance is not spoiled. As shown in FIG. 8, when there is an obstacle under the sunshade, it is possible to easily make a room that avoids the obstacle as compared with the conventional straight drawer type, and furthermore, it is possible to make a straight type. When the inclination angle of the drawer shade is large, a sense of psychological oppression is accompanied. However, such a sense of oppression can be reduced by the sun shade of the present invention. As shown in FIG. 9, if the X dimension is sufficiently ensured, the support shaft 51 is made slightly longer, and the Y dimension, which is the gap between the panels, is made slightly larger, so that direct sunlight (solid arrow in the figure) is shielded. Indirect light (dashed arrow in the figure) while performing the function of awning
Can be adopted. By changing the specifications of such a simple member, it is possible to eliminate a situation in which the interior of the room, which tends to be caused by the existing sunshade, becomes abnormally dark. In addition, in the figure, by appropriately selecting the Y dimension, the wind can be effectively released from the gap portion in the wind resistance strength surface, so that the pressure resistance load on the panel can be reduced.
