Description

[Detailed explanation of the invention] [Industrial application field] This invention is a method of attaching a rollable and unrollable cloth sheet to the eaves of buildings such as shops facing the street to avoid strong sunlight. The present invention relates to a device for adjusting the inclination angle of a sunshade sheet in the extending direction in a sunshade used.

[Conventional technology]

Various products have already been developed as this type of sunshade, but for example, in the case of the sunshade disclosed in Japanese Utility Model Application Publication No. 59-136826, both ends of the winding shaft that winds and unwinds the sheet A bracket is disposed on the seat, and the proximal end of a bendable and extensible arm, which is biased in the direction of extension of the seat by a spring, is pivotally connected to the bracket via a rotatable connecting body, and the seat is attached to the tip of the arm. The front frame is fixed to the front end of the sunshade sheet, and the inclination angle in the extending direction of the sunshade sheet is
The attachment angle between the connecting body and the bracket is adjusted by a tightening screw inserted into an arcuate long hole to adjust the elevation and depression angle of the arm.

[Problem that the invention attempts to solve]

However, in the case of a sunshade having the above structure, in order to adjust the inclination angle of the seat, the mounting angle of the bracket and the corresponding connecting body must be adjusted separately on the left and right sides, and the left and right arms must be adjusted separately. It is designed to bend and stretch using an unstable sheet stretched between the take-up shaft and the front frame as an interlocking medium, and since the angle of inclination does not necessarily match, the angle of inclination set at the time of installation of the awning is different. In addition to holding the seat for a long period of time, when changing the inclination angle of the seat, it was necessary to adjust the mounting angle between the left and right brackets and the connecting body through repeated trial and error each time.

The main purpose of the present invention is to solve the above-mentioned problem, and when adjusting the inclination angle in the direction in which the sheet is extended, by changing the installation angle between one bracket and the connecting body, the other bracket is automatically adjusted. It is an object of the present invention to provide a sunshade having an easy-to-handle inclination angle adjustment device that is provided with an interlocking mechanism that changes the mounting angle of the connecting body and the connecting body.

[Means for solving problems]

The inclination angle adjusting device according to the present invention was devised to achieve the above object, and includes a bracket for rotatably supporting both ends of the sheet winding shaft. Separately from the first bearing, a second bearing for arm tilting and a third bearing for arm interlocking are arranged in parallel, and the tilting shaft of the arm connection body base is thrust into the second bearing to allow rotation. The base end of the arm, which is always biased in the extension direction by a spring, is pivoted to the distal end of the arm connection body so as to be rotatable in a direction perpendicular to the tilting axis, and In this case, an interlocking shaft with a gear that meshes with a gear provided on the outer periphery of the arm connection body is loosely fitted, and a shaft joint is interposed between the interlocking shafts of the left and right brackets to connect the interlocking rod, and one of the brackets is The present invention is characterized in that a rotation mechanism for rotating the tilting shaft is attached to the tilting shaft that fits into the second bearing.

[Example of idea]

Hereinafter, the structure of the tilt angle adjusting device according to this invention and its operation will be explained in detail with reference to the drawings of the embodiments. In the drawings, reference numeral 1 is a sunshade made of cloth woven with cotton yarn or synthetic fiber yarn, etc. and whose surface is waterproofed. 2 is a winding shaft that holds the sheet 1 so that it can be wound up and fed out; 3 is a front frame attached to the tip of the sheet 1; 4 is a front sag connected to the sheet 1 and attached to the front frame 3; 5; Reference numeral 5 designates a bendable and extensible arm that connects the front frame 3 to its tip and moves forward and backward in a predetermined direction; reference numerals 6 and 6 designate a pair of left and right brackets that horizontally suspend and rotatably support the winding shaft 2; These structures are basically the same as conventional awnings, but in the case of the present invention,
At the bottom of the bracket 6, in addition to the first bearing 7 for the sheet winding shaft, there is a second bearing 7 for the arm tilting shaft, which will be described later.
A bearing 8 and a third bearing 9 for the arm interlocking shaft are arranged in parallel.

Of these, an arm tilting shaft 12 fixed integrally with a stop ring 11 into the center of an arm connecting body 10, which will be described next, is inserted into the second bearing 8 to rotatably support the connecting body 10, and the arm connecting body 10 is rotatably supported. A large gear 13 that rotates in the same direction as the tilting shaft 12 is provided on the outer periphery of the base of the body 10, and the base end of the arm 5 is mounted at right angles to the tilting shaft 12 at the opposite end thereof. It is pivotally connected with a pin 14 so that it can rotate in the direction. Further, the base of an interlocking shaft 16 having a small gear 15 that meshes with the large gear 13 provided on the outer periphery of the connecting body 10 is rotatably fitted into the third bearing 9, and the brackets 6 facing left and right are connected to each other. An interlocking rod 18 is connected in the lateral direction between the interlocking shafts 16, 16 of 6, respectively, with appropriate shaft joints 17, 17 such as universal joints interposed therebetween.

A tilting shaft 1 that fits into the second bearing 8 is attached to one of the left and right brackets 6, 6 (the one shown is on the left side).
A rotation mechanism 19 is provided for rotating 2.
Although there are no special limitations regarding this rotating mechanism 19,
In the case of this embodiment, fourth bearings 20, 20 are provided vertically facing each other in a direction perpendicular to the second bearing 8 inside the bracket 6, and the operating shaft 21 is rotated by the fourth bearings 20, 20. The operating shaft 21 is inserted into the operating shaft 21 so that its lower end protrudes below the bracket 6, and the engaging ring 22 is integrally fixed to the protruding end. The female screw portion 25 of the movable block 24 is screwed together, and the movable block 24 is supported so as to be movable up and down in the vertical direction by the rotation of the operating shaft 21. The base of the crank arm 26 is fixed to the end, and the crank arm 26
At the tip of the crank pin 2, the crank pin 2 engages with a horizontal groove 27 provided on the side surface of the movable block 24.
8 is protruding.

Since the sunshade equipped with the inclination angle adjustment device M according to the present invention has the above structure, the handling operation when winding and unwinding the sunshade sheet 1 is carried out by the built-in motor of the winding shaft 2 or by an external drive instead of this, as in the conventional case. When the winding shaft 2 is rotated in the direction of feeding out the sheet 1 by a device (not shown), as the tensioned portion of the sheet 1 is relaxed, the left and right arms 5, 5 supporting the front frame 3 are moved by the internal springs. (not shown) pushes the front frame 3 while gradually transitioning from the bent state to the extended state, stretches the sheet 1 as shown by the solid line arrow, and moves the winding shaft 2 in the direction shown by the dotted line arrow. When it rotates, arm 5, contrary to the above case,
5 is moved from the extended state to the bent state against the tension of the spring, and the sheet 1 can be moved backward and wound around the circumferential surface of the shaft.

In the above-mentioned handling operations, the inclination angle Q of the entire sheet 1 in the overhanging direction hardly changes, but the inclination angle Q of the sheet 1 is adjusted when installing a sunshade or adjusting sunlight due to seasonal changes. If necessary, the engaging ring 2 at the lower end of the operating shaft 21 hanging down from the bracket 6 on the side where the rotation mechanism 19 is installed
2 is engaged with a suitable hand-cranked crank rod 29 or the like and the operating shaft 21 is rotated counterclockwise or clockwise, the female threaded portion 25 screws into the male threaded portion 23 at the middle of the operating shaft 21, and the female threaded portion 25 is engaged with the male threaded portion 23 in the middle of the operating shaft 21. As a result, the movable block 24 moves up and down, and the concave groove 27 of this movable block 24 moves up and down.
The crank pin 28 and the crank arm 2 that engage with the
Since the tilting shaft 12 rotates back and forth through 6, the connecting body 10 rotates together with the tilting shaft 12, and the base end of the arm 5 connected to the tip of the connecting body 10 rotates back and forth. The inclination angle Q in the extending direction of the sheet 1 is changed.

On the other hand, when the tilting shaft 12 and the connecting body 10 on the side to which the rotation mechanism 19 is attached rotate as described above, the interlocking shaft 16 fitted in the third bearing 9 of the same bracket 6 has the aforementioned connecting body. Since a small gear 15 is provided that meshes with the large gear 13 at the base of the body 10,
The rotation of the tilting shaft 12 is transmitted through both gears 13 and 15 to the interlocking shaft 16 at the relevant position, and the rotational movement is further transmitted from the left shaft joint 17 to the other bracket via the intermediate linking rod 18 and the right shaft joint 17. The signal is transmitted to the interlocking shaft 16 provided in the arm 6, and then from the small gear 15 to the large gear 13 to the tilting shaft 12 of the connecting body 10. Therefore, when one arm 5 rotates, the other arm 5 automatically rotates. The arm 5 also rotates by the same amount, so that the inclination angle Q of the entire seat 1 in the extending direction can be adjusted accurately.

[Effect of idea]

As described above, if the inclination angle adjusting device of the present invention is applied to an awning, when adjusting the inclination angle in the direction of sheet extension during installation and use of the awning, it is possible to adjust the inclination angle in the direction in which the sheet is extended. By simply changing the mounting angle of the bracket, the mounting angle of the other bracket and the connecting body can be automatically changed to the same angle, so unlike the conventional case, there is no need to repeat the troublesome trial and error process each time. However, it is not necessary to adjust the left and right sides separately, and the inclination angle can be adjusted very quickly and accurately with a very simple handling operation, which provides an excellent usability effect.
