It is locked to. The wire lobes 66, together with the puncture struts 61 and the like, constitute a folding mechanism 68 that opens and closes the parasol section 5 in conjunction with the forward and backward movement of the arm 3.

In addition, the movable cylinder 45 in the parasol parts 5A and 5B.
45 are connected by a connecting rod 69, and the shaft bodies 42 are also connected by a connecting rod 70.

Next, the operation of the above configuration will be explained.

(1) When opening the parasol part 5; First, when the connecting member 38 is grabbed and the arm link 21 connected between the outer end 3a of the arm 3 and the column 1 is lifted, the arm 3 is connected to the column 1. It is guided by a guide plate 12 pivotally attached to the tip of the column 1 and moves toward the side of the column 1 as shown in FIG. 14 while turning around the tip side of the column 1. Along with this, the movable cylinder 45 suspended by the wire rope 66 begins to be pulled up by the wire rope 66, so the angle of the puncture support column 61 with respect to the vertical axis 41 increases, and the roof rib 6 begins to expand. .

When the arm 3 is completely extended from the tip of the support column 1, the receiving member 27 of the operation link 26 stops the receiving from the outside near the connecting portion of the arm link 21 with the arm 3. At this time, the movable cylinder 45 pulled up by the wire lobe 66 fits into the center shaft 44, and the roof rib 6 is displaced to the maximum expansion position via the puncture support 61, as shown in FIG. 1, and the seat 7 is expanded. . As a result, each parasol portion 5 is completely opened, and the clip member 36 connects the base end side of the operation link 26 and the arm link 21.
etc. to hold it in the above state.

In this case, since the parasol part 5 is cantilevered to the support 1 via the arm 3, the parasol part 5 can be installed even on a narrow piece of land. Furthermore, the plurality of parasol sections 5 can be opened at any time with one-touch operation, and the wide roof makes it easy to use.

(2) When closing the parasol part 5; After removing the clip member 36 that fastens the operating link 26 and arm link 21, grasp the connecting member 39 and move the operating link 26 clockwise with the bin 19 as a fulcrum. If the arm link 21 is rotated and displaced until the receiving member 27 fixed to each operation link 26 is positioned on the upper surface side of the arm 3 through the connecting portion between the arm link 21 and the arm 3, the arm link 21 Since the lock on the uke is released,
Each arm 3 has a roll 17 of the guy plate 11 due to its own weight.
20 and began to retreat. Since the outer end of each arm 3 is connected to the column 1 via the arm link 21, the arm 3 begins to pivot counterclockwise about the pin 25 while moving backward as shown in FIG. At this time,
The roof frame 6A corresponding to the arm 3 above is also an L-shaped frame 2.
It retreats almost along the arm 3 while being guided by the roll 31 of 9.

Since the movable cylinder 45 is pulled up by the wire rope 66 as the arm 3 retreats, the roof frame 6 is folded toward the vertical shaft 41 via the puncture support column 61. When the arm 3 moves back to the storage position along the support column as shown in FIG. 15, the movable cylinder 45 also moves to the lowest position.
The roof frame 6 is also completely folded together with the sheet 7.

In this case, as the arm 3 retreats to the storage position along the column, the parasol part 5 is folded and moved toward the column 1, so that the space on the side of the column 1 can be used without wasting it. .

In addition, as the arm holding mechanism 35, the operation link 26
Although the arm link 21 has been described as being rotatably operated, it is also possible to adopt a configuration in which the arm link 21 is driven by a rotary screw or the like driven by a motor instead of this.

Further, in the above embodiment, the parasols 5A and 5B corresponding to the two pillars 3A and 3B are opened and closed, but the number of pillars 3 is further increased to open and close three or more parasols 5 at the same time. Even if there is, the same effect will be achieved.

[Effects of the Invention] As described above, according to the present invention, the parasol portion is supported at each inner end portion of the plurality of arms extending laterally at the upper ends of the plurality of support columns, and the retracting operation of the arms is supported. Since the parasol part is folded around the support while being pulled toward the support in an interlocking manner, it is possible to effectively utilize the space around the support in the folded state.

In particular, since the arm links connected to the arms can be connected to each other and the parasol section can be opened and closed integrally via each arm, it is possible to immediately meet the needs of a large roof area.
