Description

[Detailed Description of the Invention] [Industrial field of application] This invention provides a sunshade sheet wound around a shaft at the entrance or exit of a building frame or above a window, and a front frame is provided at the tip of the sunshade sheet. An arm bent at a more middle portion is provided in a protruding manner, and the tip of the arm is connected to the front frame,
Moreover, the present invention relates to a device for supporting the apron in the front frame in the awning where the apron is caught in the front frame.

[Conventional technology]

As this type of device, for example, the one disclosed by Japanese Utility Model Laid-Open No. 59-71825 is known, and the technology of the publication is
A winding shaft around which an eave sheet (apron) is wound is installed in the eave frame (front frame), and a worm and a worm wheel are attached to the shaft.
This is a structure in which the rotation transmission means by means of a lever is connected, and the eaves-driving sheet can be drawn out or rolled up by rotating the worm.

[Problems to be solved by the device]

The apron mentioned above can be hung with the same width as the awning sheet and with almost the entire width of the front frame. If the awning width is within about 2 m, there is almost no problem, but more than that. If it has a width, the length of the winding shaft around which the apron is wound becomes long, and it is not possible to support it in the middle.Therefore, the winding shaft bends in the middle, and the apron feeding and winding operation cannot be performed smoothly. was there.

Therefore, the present invention provides a sunshade apron support device that can smoothly rotate even if an apron with a long width is not bent, and that can be paid out and wound up evenly over the entire length. To do.

[Means for Solving the Problems]

The solution according to the present invention is a awning apron support device in which a winding shaft around which an apron is wound is installed in a front frame provided at the tip of a awning sheet protruding from a building frame, and a rotary drive device is connected to the winding shaft. A cap fixed to both ends of the front frame is provided with vertically long bearings, and an apron having the winding shaft wound around the bearing is installed between the bearings so that the apron can contact the inner bottom surface of the front frame. And a rotary shaft drive intervenes between the rotary drive device.

[Action]

Since the winding shaft is engaged with the long bearing up and down, the diameter of the apron wound around the winding shaft gradually decreases as the apron is drawn out. The shaft is supported by the inner bottom surface of the front frame through a layer of an apron wrapped around the shaft to prevent the shaft from bending. Of course, when the apron is wound up, the bending is also prevented. Further, since the shaft coupling is interposed between the winding shaft and the rotation driving device, the rotational force of the rotation driving device can be transmitted even if the winding shaft moves up and down.

〔Example〕

Before explaining the apron support device according to the present invention, the structure of the awning will be described. As shown in FIG.
The winding shaft 3 around which the sunshade sheet 2 is wound is pivotally supported between the brackets 1 and 1 fixed to the body of the building, and the support rod 4 is installed, and the front frame 5 is attached to the tip of the sunshade sheet 2 to support it. A pair of arms 6 and 6, which are biased by springs in the direction in which they are refracted and bent at the middle portion, are provided on the rod 4 so as to be swingable in the lateral direction, and the tips of the arms 6 and 6 are also attached to the front frame 5. The awning sheet 2 is swingably connected and can be rotated automatically or manually by rotating the winding shaft 3.
At the same time that the arms 6 and 6 are extended, the arms 6 and 6 are extended, and conversely, at the same time when the awning sheet 2 is wound, the arms 6 and 6 are folded and stored on the side of the body.

A winding shaft 8 around which an apron 7 is wound is rotatably supported in the front frame 5, and its supporting device is shown in FIGS. 1 to 5, and the front frame 5 is shown in FIG. As shown in the figure, it has an awning sheet receiving groove 9 in the rear part of the upper surface, an arm receiving groove 10 in the rear part of the lower surface, and an arc surface is formed between the front surface and the bottom surface, and an apron 7 is formed in the arc surface. The opening 11 for feeding is open. Caps 12, 1 are attached to both ends of the front frame 5, respectively.
3 is fitted, and the cap 12 on the left side of FIG.
As shown in the figure, a bearing 14 consisting of a vertically elongated oval groove is provided on the inner surface thereof, and the right-side cap 13 is inclined similarly to the bearing 14 as shown in FIG. A bearing 15 composed of an oval through hole is formed, and a support shaft 16 protruding from the winding shaft 8 is engaged with a bearing 14 of a left cap 12 slidably in the longitudinal direction of the bearing 14.
When the end of the winding shaft 8 is also slidably engaged with the other bearing 15 and the apron 7 is wound around the winding shaft 8, the outer surface of the apron 7 is supported by the bottom surface of the front frame 5. , As the apron 7 is pulled out, the winding shaft 8
It descends along 14,15 and the outer surface of the apron 7 is always the front frame 5.
It is formed so as to be supported on the bottom surface of the. Since the opening 11 is not below the center of the winding shaft 8 but obliquely below it, the bearings 14 and 15 are formed to be inclined.

Further, as shown in FIG. 1, a rotation driving device 17 is fixed to the outer surface of the cap 13 provided with the bearing 15 composed of a through hole. The illustrated rotary drive device 17 is composed of a worm 18 and a worm wheel 19, and has an operating rod at the lower end of the worm shaft 20.
A ring 23 protruding from which a hook 22 of 21 can be engaged is provided. In addition, the winding shaft 8 and the rotation drive device 17 are mixed with each other so that the shaft joint 24
As an example of the cross shaft joint 24, the Oldham joint shown in FIG. 5 is used. The joint is such that the first disc 26 is fitted on the worm wheel shaft 25, the third disc 28 is fixed on the winding shaft 8, and the second disc 27 is formed between the two discs 26, 28 and the ridges 29, 30 orthogonal to each other. The concave grooves 31 and 32 are interposed due to the engagement relationship.

Due to the above-mentioned structure, the shaft joint 24 is misaligned when the apron 7 is fed out by rotating the worm shaft 20 and when it is wound up.
Thus, the winding shaft 8 rotates while sliding up and down.

[Effect of device]

According to the sunshade apron support device according to the present invention, the winding shaft around which the apron is wound is vertically slidably installed in the front frame, and regardless of the size of the layer of the apron around which the winding shaft is wound, the apron is always supported. It is supported on the bottom surface of the front frame via the, and even if the front frame is long and the apron is wound over its entire length, the winding shaft is supported on the bottom surface of the front frame via the apron. Since the winding shaft is supported over the entire length, the apron can be uniformly and smoothly unwound and unwound over the entire length by rotating while maintaining the axis without any bending. It is a thing. Further, since the shaft joint is interposed between the winding shaft and the rotation drive device, even if the winding shaft moves up and down and its axis disagrees with the axis center of the rotation drive device, the rotational force is surely transmitted. It is something that can be done.
