Description

[Detailed explanation of the invention] [Industrial application field] This invention is installed outside the open room of a building,
A sunshade in which a front frame is fixed to the front end of a sunshade sheet wound around a winding shaft, the front frame is supported by a telescopic support arm, and the sunshade sheet is extended and retracted as the winding shaft rotates. The present invention relates to a winding shaft adjusting device that prevents the winding shaft from bending in the stretching direction when stretching a sunshade sheet.

[Conventional technology]

As shown in FIG. 5, this type of sunshade has a winding shaft 3, on which a sunshade sheet 2 is wound, rotatably installed between a pair of brackets 1, 1.
A front frame 4 is attached to the tip of the bracket 1, and a support punch 5 parallel to the winding shaft 3 is provided between the brackets 1, 1, and a support arm 6 is attached to the support punch 5, which is bent in the middle.
The front frame 4 is connected to the tip of the support arm 6, and the support arm 6 is biased in the direction of extension by a spring provided inside the support arm 6. This awning may be half the length of the winding shaft shown in Figure 5, depending on the structure to which it is installed.
Alternatively, there is a type that is twice as long as shown in Fig. 5, and the longer type supports the front frame with four support arms.

[Problem that the invention attempts to solve]

In the above-mentioned sunshade, as the winding shaft is rotated, the support arm is sequentially extended by a spring force to extend the sunshade sheet. By the way, if the winding shaft is short as mentioned above, there is no problem with the difference in length, but if it is long, the winding shaft will curve in the direction of arching out when the sunshade sheet is stretched out, and the There was a drawback that the sunshade sheet was stretched out at an angle due to the difference in resistance.

This invention aims to solve the above-mentioned conventional drawbacks, and it prevents the winding shaft from curving into an arched shape. The object of the present invention is to provide a regulating device that prevents the winding shaft from curving in response to different diameters when the winding shaft is wound around the winding shaft.

[Means for solving problems]

The awning winding axis regulating device based on this invention is
In a sunshade in which a front frame is fixed to the front end of a sunshade sheet that overhangs from a winding shaft, and a telescopic support arm is connected to the outer front frame, the leading end faces the bottom of the winding shaft and winds up. A fixed arm is provided standing up in front of the shaft, and an eccentric roller parallel to the winding shaft is provided at the tip end of the fixed arm.

〔Example〕

FIG. 5 shows a conventional awning equipped with a regulating device according to this invention, and the regulating device is provided in the middle of the winding shaft 3.

As shown in FIGS. 1 to 3, the regulating device has a frame-shaped holder 9 suspended from a stay 8 fixed to a building frame 7, and a holder 9 that protrudes downward from the inside of the holder 9. A curved fixed arm 10 is provided to protrude orthogonally below the winding shaft 3, and the curved form of the fixed arm 10 is such that the first core 11a and the first core 11a are offset back and forth as shown in FIG. It is formed by a combination of circular arcs drawn around two cores 11b, and its width is larger than that formed by a single circular arc. However, although the fixed arm 10 does not necessarily have to be curved, it is necessary that the distal end of the fixed arm 10 protrudes in front of the winding shaft 3 and stands upwardly. By the way, fixed arm 1
0 protrudes from the holder 9, the rear end of the fixed arm 10 is pivotally supported by a stop pin 12, and is fixed to the holder 9 with a stop bolt 13.
By forming the fixing bolt 13 of the holder 9 into a long hole (not shown), the protruding angle of the fixed arm 10 can be adjusted.

A plurality of rollers 14, 15, 16 are attached to the winding shaft 3 in the rear section from the tip of the fixed arm 10.
Each roller 14, 1 is provided parallel to the axis of the
Both rollers 5 and 16, or particularly only the roller 14 at the tip, are rotatably provided on a support shaft 19 with a shaft 18 eccentrically protruding from the head 17, as shown in FIG.

A top plate 20 is provided on the upper surface of the holder 9 and projects forward to prevent the sunshade sheet 2 from floating up. Further, a holding part 21 for holding the support punch 5 is provided at the lower part of the holder 9.

In the case shown in FIG. 1, the rollers 14, 15, and 16 are set so as to contact the outer peripheral surface of the sunshade sheet 2 when the sunshade sheet 2 is rolled up. In the case shown in FIG. 4, only the roller 14 at the tip can be eccentric, and in this case,
The other rollers 15 and 16 do not contact the sunshade sheet 2, but the roller 14 at the tip contacts the outer peripheral surface of the sunshade sheet 2 due to eccentric tension. Therefore, when the sunshade sheet 2 is stretched out, the winding shaft 3 is the heaviest and is subjected to a large moment, so a force that bends the winding shaft 3 in the direction in which the sunshade sheet 2 is stretched out acts. roller 1
4, the winding shaft 3 can be prevented from bending and can be stretched out while maintaining a straight state.

[Effect of idea]

If the sunshade winding axis adjusting device according to this invention is installed, a fixed arm that protrudes forward from the winding shaft is provided below the winding shaft and has its tip raised, and the raised tip of the fixed arm An eccentric roller is installed parallel to the winding shaft.If the eccentric roller is adjusted and set so that it is in contact with the outer circumferential surface of the sunshade sheet wrapped around the winding shaft, the winding shaft will move when the sunshade sheet is stretched out. Since the deflection of the sunshade sheet is prevented by the rollers, even if the winding shaft is long, the sunshade sheet can be stretched normally and smoothly without tilting. In addition, since the roller is eccentric, the amount of protrusion from the fixed arm can be adjusted, so even if the rolled-up sunshade sheet has a different diameter, it can be adjusted accordingly to ensure that it contacts the outer peripheral surface of the sunshade sheet. This is something that can be done.
