Description

[Detailed Description of the Invention] The present invention relates to a device for winding up and unrolling a sunshade provided on the roof of a sunroom or the like.

A sunroom has a roof section made of a light-transmitting plate, allows sunlight to enter the room, and is used as a greenhouse, a living room, or the like.

In such a sunroom, the indoor temperature may become too high when sunlight energy is strong, such as in summer.

Therefore, the applicant first provided a sunshade on the roof, and by winding up and unrolling this sunshade with a winding drum, the roof could be covered with the sunshade or opened. I applied for a sunroom that looked like this.

In the above-described sunroom, if the winding drum is driven by a motor to automatically wind up and unwind the sunshade, it is possible to easily cover and open the roof with the sunshade.

However, when winding up an awning with a winding drum, the awning can be wound up smoothly, but when it is unrolled from a winding drum, it is unwound due to its own weight, rigidity, etc. Therefore, there is a problem that the awning cannot be extended smoothly.

The present invention was developed in view of the above circumstances, and its purpose is to cover or open a sunshade provided on the roof by rotating a winding drum using a motor. Another object of the present invention is to provide a sunshade winding/unwinding device capable of smoothly unwinding the sunshade wound around a winding drum by utilizing the rotation of the winding drum.

The first pulley 62 is attached to a mounting piece 66 provided at the tip of the vertical wall 23a of the auxiliary rafter 23 located in the middle so as to be able to swing vertically, and the second pulley 63 is attached to the mounting piece 66 provided at the tip of the vertical wall 23a of the auxiliary rafter 23 located in the middle. It is attached to a mounting piece 67 provided at the outer tip of the lower horizontal piece 26 so as to be able to swing up and down, the third pulley 64 is attached to the outer middle part of the lower horizontal piece 26, and the fourth pulley 65 is attached to a spring The spring 68 is tension-biased toward the tip side, and is configured so that tension is applied to the spring 68 when the rope 61 is wound around the pulley 42.

Note that the left and right vertical pieces 27, 2 of the sunshade guide member 24
Notches 27a and 28a are formed at the tip of the rope 8 to prevent interference with the rope 61.

Since it is like this, when the winding drum 32 is rotated in the feeding direction and the shade 22 is fed out, the pulley 4
Since the rope 61 is wound up by the rope 61, the awning 22 is pulled by the rope 61, and the awning 22 can smoothly move to the tip and cover the roof.

At this time, the amount of winding out of the shade 22 per rotation of the winding drum gradually decreases (in other words, since the shade 22 is wound around the winding drum 32 several times,
(As the shade 22 is unwound, the diameter becomes smaller and the unwound amount is gradually decreased.) However, since the pulley 42 rotates once per rotation of the winding drum, if the winding amount of the rope 61 is constant, the rope 61 The amount of winding and the amount of daylight feeding out do not match,
2. The rope 61 may be damaged, but the outer peripheral surface 44 of the pulley 42 is tapered, and the rope 61 is wound around the spiral groove 45 formed on the outer peripheral surface 44, and when the pulley 42 rotates, the rope 61 Since it is configured to wind up the rope 61 sequentially toward the small diameter side, the amount of winding of the rope 61 by the pulley 42 is gradually reduced, and no unreasonable force is applied to the awning 22 and the rope 61. 22 can be pulled smoothly.

Furthermore, when the winding drum 32 is driven in the winding direction to wind up the shade 22, the pulley 42 rotates in the unwinding direction and pays out the rope 61, so that the pulley 42 operates to avoid low resistance when winding the shade 22. do.

At this time, the winding amount of the sun shield 22 on the winding drum 32 increases sequentially, but the amount of the rope 61 fed out of the pulley 42 increases sequentially, so the winding amount of the sun shield 22 on the winding drum 32 increases gradually.
2 can be rolled up to open the roof.

Further, since the fourth pulley 65 is tensioned by a spring 68, it is possible to prevent excessive tension from being applied to the rope 61 or from sagging the rope 61 during the above-mentioned unwinding and winding operations of the awning 22.

Note that instead of pulling the fourth pulley 65 with the spring 68, a tension spring may be interposed between the ropes 61.

A mechanism 70 for detecting the upper limit (opening limit) and lower limit (closing limit) of the sun shade 22 is provided near the feeding and winding sides of the pulley 42.

That is, a mounting plate 71 is fixed on the side of the ridgepole 15 on the upper wall 23b of the auxiliary rafter 23, and a U-shaped bracket 72 is attached to the mounting plate 71.
A horizontal shaft 73 is provided perpendicularly to the rope 61 between a and a, and an auxiliary pulley 74 is provided on the horizontal shaft 73 so as to be slidable in the axial direction. 45, the rope 61 is wound around the pulley 42, and when the rope 61 is unwound, the auxiliary pulley 74 slides along the horizontal shaft 73. Limit switches 75 ₁ and 75 ₂ are provided at intervals in the direction of movement of the auxiliary pulley 74, and
2 on the winding drum 32 and the roof is completely opened (that is, at the upper limit), the auxiliary pulley 74
turns on the first limit switch 75 ₁ and turns on the sun shade 2.
2 is extended to completely cover the roof (that is, at the lower limit), the auxiliary pulley 74 turns on the second limit switch ₇₅₂ .

As a result, the upper and lower limits of the sun protection 22 can be detected by the first and second limit switches 75 ₁ and 75 ₂ , and the motor 36 can be controlled to stop using the detection signals.
There is no need to unnecessarily wind up or extend out the shade 22 too much.

In addition, a solar radiation sensor and an anemometer are installed so that when the amount of sunlight reaches a certain amount, the sun shade 22 is automatically extended, and when the wind speed reaches a certain level, the sun shade 22 is automatically extended.
2 is automatically wound up, the first and second limit switches 75 ₁ and 75 ₂
The motor 36 can be stopped by detecting the upper and lower limits of 2.

Note that the movement of the rope 61 is controlled by the first and second limit switches 75 ₁ and 75 ₂ without providing the auxiliary pulley 74.
Alternatively, the upper and lower limits of the sunshade 22 may be detected by direct detection.

Since the present invention is configured as described above, the motor 36
By rotating the winding drum 32 by
2 can be rolled up and unrolled to open or cover the roof section, making it possible to easily operate the sunshade 22.

Further, when the winding drum 32 is rotated in the unwinding direction, the rope 61 is wound around the pulley 42, and the rope 61 is wound up by the pulley 42.
2 is pulled, so the sunshade 22 can be smoothly extended.

In addition, since a spring 68 is provided to apply tension in the longitudinal direction to the rope 61, it is possible to absorb and relieve an appropriate amount of tension acting on the rope 61, thereby preventing the rope 61 from being damaged. It can prevent you from getting hit.
