Description

[Detailed explanation of the invention] [Industrial application field] This invention is installed outside the open room of a building,
The front frame is fixed to the front end of the sunshade sheet wrapped around the winding shaft, and the front frame is supported by a support arm that is foldably protruded from the vicinity of the winding shaft and is biased in the extension direction by elastic force. The present invention also relates to a device for supporting the support arm of the sunshade on a bracket in the case of a sunshade in which the sunshade sheet is extended and retracted as the winding shaft rotates.

[Conventional technology]

As a conventional awning, for example, Japanese Patent Application Laid-Open No. 55-95763
The one described in the No. Publication is known. As shown in FIG. 5, the support device for the support arm in the publication includes a support plate 21 that is pivotally supported on a bracket 20 by a flexible pin 22, and
A plurality of adjustment holes 22 are drilled at equal intervals along a circular line drawn with the flexible pin 22 of 1 as the center, and the fixing bolts 24 inserted into the appropriate adjustment holes 23 are screwed into the bracket 20. By selecting the adjustment hole into which the sunshade sheet is inserted, the angle at which the sunshade sheet extends can be adjusted. Moreover, the sheet storage roll 25 is pivotally supported on the support plate 21.

[Problem that the invention attempts to solve]

According to the technique described in the above publication, the storage roll 25 and the support arm 26 are held on the support plate 21, the entire weight of the sunshade is applied to the flexible pin 22 and the fixing bolt 24, and the angle For adjustment, the support plate 21 may be rotated by a predetermined angle, but since the weight of the storage roll 25, the seat, and the support arm 26 is added to the support plate 21, there is a problem that it is heavy and cannot be easily operated.

The object of this invention is to provide a support arm support device for a sunshade which is light and easy to operate and allows fine adjustment of the projection angle of the sunshade.

[Means for solving problems]

In this invention, a disk is fixed to a bracket on which a winding shaft is installed using a support shaft, and a plurality of screw holes are drilled at irregular intervals on a concentric circle of the disk, and the screw holes are made at irregular intervals to correspond to the concentric circle of the bracket. A plurality of through holes are drilled along the circumference, a set bolt is screwed into a matching screw hole from at least one of the through holes, and a support arm is connected to this disk via a pivot pin.

〔Example〕

As shown in the sunshade in Fig. 4, a winding shaft 2 is installed between a pair of left and right brackets 1, 1, and support arms 3, 3 are protruded from the lower ends of both brackets 1, 1. Sunshade sheet 4 wrapped around 2
The front end of the support arm 3 is fixed to the front frame 5, and the support arm 3 is formed so that it can be folded in the middle and is biased so as to be extended by a spring force. It supports frame 5,
By rotating the winding shaft 2 by the rotary drive device 6, the support arms 3, 3 are extended by spring force, and the sunshade sheet 4 is extended.
Further, by winding the sunshade sheet 4 around the winding shaft 2, each support arm 3, 3 is folded and stored.

Therefore, as shown in FIGS. 1 to 3, this device is provided with a circular depression 8 in the side wall below the bearing 7 that supports the winding shaft 2 of the bracket 1.
A disk 9 is loosely fitted into the recessed portion 8, and a support shaft 10 consisting of a bolt inserted through the center passes through the side wall of the bracket 1 and is fastened with a nut 11. By loosening the nut 11, the disk 9 is rotated. I can do it. Two prongs 12 are provided protrudingly on the plate surface of the disk 9, and the base of the support arm 3 is fitted between the two prongs 12, and a pivot inserted between the two prongs 12 and the base of the support arm 3 is provided. It is rotatably connected to the disk 9 by a support pin 13. Furthermore, bracket 1 of disk 9
A plurality of screw holes 14 are provided at unequal intervals in the circumferential direction along concentric circles drawn on the plate surface facing the plate, and specifically, for example, 15 degrees intermediate from the screw hole at one end. Provided at an interval of 7.5° from the screw hole. On the other hand, a plurality of through holes 15 are bored in the side wall of the bracket 1 corresponding to the recessed portion 8 at equal intervals along a concentric circle equal to the circle of the screw hole 14, specifically, at intervals of 30 degrees, for example. It is provided. Then, one through hole 15 matches the screw hole 1.
4 and a stop bolt 16 screwed together.

Note that the aforementioned winding shaft 2 has a journal 18 having a spherical surface on the support shaft 17 that protrudes from the winding shaft 2.
It is constructed by loosely fitting the journal 18 into the ball joint bearing 19 provided on the bracket 1, and even if the center of each bearing 19, 19 of both the left and right brackets 1, 1 is slightly out of alignment, it can be fixed. The winding shaft 2 is constructed such that the winding shaft 2 is allowed to stand.

According to the above embodiment, when installing the awning outdoors, the brackets 1, 1 are fixed to a building, and the winding shaft 2 is installed between both brackets 1, 1, and then the support arms 3, 3 are attached to the bracket 1. , 1, and the tips of the support arms 3, 3 are connected to the front frame 5, but the support arms 3, 3 are fixed to the brackets 1, 1.
When mounting the support arm 3 on the base of the support arm 3, the disc 9 provided at the base of the support arm 3 is loosely tightened with the support shaft 10 and the nut 11 so that it can rotate freely, and the stop bolt 16 is screwed into the screw hole 14 through the through hole 15. However, at this time, the extension angle of the sunshade sheet 4 is set by holding the support arm 3 and rotating the disk 9 to select screw holes 14 that have different phases. At that time, the screw holes 14 into which the stop bolts 16 are screwed are basically in the same phase on the left and right brackets 1, 1, but the installed winding shaft 2 is If the front frame 5 is slightly out of place vertically, it is possible to adjust the front frame 5 so that it projects horizontally by using screw holes with different phases in the left and right support devices.

[Effect of idea]

According to the support arm support device for an awning according to this invention, since the support arm is attached so that its angle can be adjusted freely without receiving the load of the winding shaft of the bracket, the load of the winding shaft is reduced when the angle is adjusted. It can be adjusted without being subjected to any stress, and the adjustment operation can be performed easily and easily. In addition, the means for adjusting the angle is such that a disk is provided on the bracket so as to be rotatable around a support shaft, a plurality of screw holes are drilled in the disk at irregular intervals along the circle, and the circumference of the bracket is the same as the circumference of the screw holes. Multiple through holes are drilled at equal intervals along a circle, and a stop bolt passed through at least one hole is screwed into the screw hole.The phases of the through holes and screw holes are different, so the sunshade sheet The overhanging angle can be finely adjusted, and even if the winding shaft is installed with a slight vertical deviation, the front frame can be kept horizontal and the front frame can be extended to maintain the normal overhanging position. .
