Description

[Detailed description of the invention] [Industrial application field] This invention relates to awnings installed at the eaves of shops and other shop windows, and is particularly concerned with awnings installed in the eaves-like shape of eaves overhanging the eaves. The object of the present invention is to provide a sunshade whose extension angle can be adjusted.

[Conventional technology] Conventionally, sunshades such as shutter windows for shops and buildings have been designed to
There are some that allow you to adjust the length of the awning overhanging the eaves.

Incidentally, the angle of incidence of sunlight changes depending on the seasons and the time of day.

Therefore, in order to enhance the functionality as a sunshade, it is preferable that not only the length of the overhang from the eaves can be adjusted, but also the angle of the overhang.

[Problem that the invention attempts to solve]

Of course, various mechanisms have been devised in the past in order to make the length of the extension and the angle of the extension freely adjustable.

However, conventional devices generally have complicated mechanisms and are difficult to operate.

Therefore, the present invention is particularly easy to assemble.
Moreover, it was devised for the purpose of providing a sunshade whose extension angle can be easily adjusted.

[Means for solving problems]

In order to achieve the above object, the present invention uses a bracket on the wall of a building to horizontally suspend a winding shaft wrapped with a sunshade sheet so as to be rotatable, and a parallel bar is arranged in front of this winding shaft. At the same time, an arm is extended forward from a position below the winding shaft, the front end of the arm is connected to the bar, and a sunshade sheet is extended between the bar and the winding shaft to form an eaves. In the awning, a fixing member having a circular circumferential surface with a stopper protruding from the circumferential surface is provided at a position below both ends of the winding shaft, and the fixing member is further provided with an angle having a diametrically projecting flange on the outer circumferential surface. Rotatably insert the adjustment tube, drill a screw hole in the flange of the angle adjustment tube, screw in a threaded rod, bring the tip of the threaded rod into contact with the stopper of the fixing member, and screw in the screw rod; A mechanism in which the rotation angle of the angle adjustment tube can be freely adjusted with respect to the fixed member by unscrewing, and the proximal end of the arm is connected to a lug protruding from the outer periphery of the rotation tube. It is composed of

[Effect]

Since the present invention is constructed as described above, the rotation angle of the angle adjustment tube relative to the fixed member can be adjusted by operating the threaded rod. For example, by rotating the angle adjustment tube clockwise, the angle can be adjusted. The fulcrum of the proximal end of the arm connected to the tube is displaced upward, and as a result the front end of the arm is moved upward. The upward movement of the front end of the arm results in an upward displacement of the front end of the eave.

In other words, the extension angle of the sunshade sheet is increased.

〔Example〕

Further, the present invention will be specifically explained based on embodiment figures. First, FIG. 1 shows the structural mechanism of the sunshade of the present invention, and 1 is a winding shaft for winding up the sunshade sheet 3. As shown in FIG.

This winding shaft 1 is rotatably mounted horizontally on a bracket 2 fixed to a wall surface W at both ends thereof. The bracket 2 is, of course, fixed to the upper wall surface W of a window or shower window through which sunlight shines, or around the upper stile.

The front edge of the sunshade sheet 3 wound around the winding shaft 1 is fixed to a bar 4 made of a metal pipe.
The bar 4 and the winding shaft 1 are arranged in parallel.

Next, an arm 13 is stretched between the bracket 2 that supports the winding shaft 1 and the bar 4 from a position below both ends of the winding shaft 1, and the entire structure is formed into an eave shape as shown in FIG. has been done.

As described above, two arms 13 are extended from below both ends of the winding shaft 1, but if the span of the sunshade sheet 3 is long, three arms 13 are extended from the middle of both ends. In some cases, more than one of these may be provided. Further, in FIG. 1, 5a is a worm gear fixed to the shaft end of the winding shaft;
b is a worm that meshes with this worm gear 5a, and a crank-shaped handle 7 is linked to an annular portion 6 that is integrated with this worm 5b, and winds and unwinds the sunshade sheet 3 wound around the winding shaft 1. It is something.

The present invention is a sunshade in which the sunshade sheet is configured in a roll-up manner as described above, in which a mechanism for attaching the base end of the arm 13, which is one of the members forming the eaves, is devised. will be explained based on the embodiment shown in FIG.

First, in FIG. 3, the square shaft 8 located below the winding shaft 1 is a core material for attaching the fixing member 9.
It is parallel to the winding shaft 1 and has brackets 2 at both ends.
It is fixedly attached to the

The fixing member 9 is externally fixed to both ends of the square shaft 8, and is shaped like a short tube, and has a circular outer circumferential surface. In FIG. 3, reference numeral 9a is a notch provided to fix the fixing member 9 to the square shaft 8 in a non-rotatable manner.

Furthermore, the fixing member 9, which has a short tubular shape and has a circular outer peripheral surface, has a stopper 17 protruding from its outer periphery. Further, a half-split angle adjustment tube 10 is rotatably inserted into the fixed member 9.

That is, the halved angle adjustment tube 10 has flanges 10a and 10b extending in the diametrical direction, respectively.
is provided, and the flanges 10a and 10b are
As shown in the figure, by tightening with bolts 11, it is rotatably fitted onto the fixing member 9.

By the way, as mentioned above, the short tubular fixing member 9
has a stopper 17 protruding from its outer periphery. Therefore, in this embodiment, a window-shaped opening 16 is provided on one side of the half-split angle adjustment tube 10, the right side member in FIG. A stopper 17 of the fixing member 9 is projected outward from the opening 16.

Further, screw holes are bored in the flanges 10a and 10b located below the angle adjustment tube 10, facing the stopper 17 side of the fixing member 9, and a threaded rod 15 is inserted into the screw holes as shown in FIG. Insert the threaded rod 15 into the stopper 1 of the fixing member 9.
It is placed in contact with 7.

Next, a lug 12 is provided protruding from the outer periphery of the angle adjustment tube 10, and the proximal end of the arm 13 is connected to this lug 12 with a pin 14a.

In FIG. 3, reference numeral 18 denotes a square shaft for operating the threaded rod 15, and an operation handle is linked to the square shaft 18 to screw in and unscrew the threaded rod 15.

Further, when winding up and unwinding the sunshade sheet 3 onto the winding shaft 1, the arm 13, which is stretched between the front edge of the sunshade sheet 3, that is, the bar 4, and the winding shaft 1 side, as shown in FIG. As shown in , a bent part 13a is provided in the middle part, and when the sunshade sheet 3 is wound up and rewound, a "ku" is formed at the bent part 13a.
It has a structure that allows it to be bent in the shape of a square, allowing adjustment of the length of the awning sheet.

Since the present invention has the above-mentioned configuration,
When the threaded rod 15 is screwed from the position shown in FIG. 3 to the position shown in FIG.
5 is in contact with the stopper 17 of the fixed member 9, the angle adjustment tube 10 rotates clockwise relative to the base end of the arm 13, that is, the lug 12 of the angle adjustment tube 10. The position of the connecting pin 14a at the base end of the arm 13 is displaced upward.

As a result, the position of the tip of the sunshade forming the eaves moves upward, that is, the projecting angle of the sunshade opens upward, and the incident angle of sunlight can be adjusted.

FIG. 5 is an operation diagram for adjusting the extension angle of the awning. Note that if you unscrew the threaded rod 15 instead of screwing it in as explained in FIG. 4 above,
Since the tip of the threaded rod 15 is separated from the stopper 17, the angle adjustment tube 10 is tilted downward by the weight of the tip side of the sunshade sheet 3, bar 4, and arm 13.
Contrary to the case in FIG. 5, the overhang angle operates in the direction of narrowing.

In addition, in the embodiment, as shown in FIG.
In this example, the vertical movement of each arm 13 is performed by each arm 13.
I am starting to do it every time. However, for example, the base ends of both arms 13, 13 are connected to each other by a reinforcing bar (not shown).
It is also possible to connect the arms 13 with the arm 13 so that both arms 13 can be moved up and down by only moving one arm 13 up and down.

[Effect of idea]

As explained above, according to the present invention, the projecting angle of the sunshade forming the eaves can be easily adjusted by simply rotating the threaded rod.

In particular, the sunshade sheet is a roll-up type, and the arm is foldable, so
If the adjustment of the overhang length by this winding operation and the adjustment of the overhang angle of the present invention are used together,
It is possible to always ensure highly functional light shielding as a sunshade.

In addition, the structure is simple, and the angle adjustment tube that connects the base ends of the arms and moves the connection fulcrum up and down is made of a short, half-tubular material, making installation and assembly easy. be.

Furthermore, the overall structure is extremely simple, making it ideal for use as a sunshade.
