JP5671287B2 - Awning device - Google Patents

Description

  The present invention relates to a sunshade which is attached to the outside of a window and has a light shielding function and a ventilation function by extending the screen, and in particular, for a type protruding outward, such as a protruding window and a sliding window, a predetermined distance between the window and the screen. The present invention relates to a sunshade device that can shield light while ensuring ventilation by forming a space.

In order to prevent excessive sunlight from entering through the outer wall window, it has been practiced to attach a bag or a roll screen to the outside of the window.
In recent years, there has been an increasing need for an awning device that can cope with changes in lifestyle, such as a window that protrudes outward from a wall surface, such as a protruding window or a sliding window, or a need to dry laundry.
For example, Patent Document 1 discloses an awning (an awning) that projects a screen outward by tilting an arm connecting the lower ends of the screen outward using link mechanisms provided on the left and right sides of the window.
However, the link mechanism disclosed in the same publication is such that the lower end of the arm rises along the slide rail, and the tip falls to the outside. It is not possible to shield the entire window opening while providing a predetermined space outside.
Patent Document 2 discloses an awning device that forms a rectangular space on the outside of a window with a drawn-out screen and vertical members on both sides.
However, the technique disclosed in the publication forms a rectangular space after the screen is once extended to the lower side of the window, and the operation mechanism is complicated.

Japanese Patent Laid-Open No. 2003-268843 JP-A-8-27981

  The present invention is simple in structure and excellent in operability, and in various usage modes in which a predetermined space is formed between a screen and a wall (window) in the state of a ridged state, a total light shielding state, and a total light shielding state outside the window. An object of the present invention is to provide an awning device that can be easily switched.

  The sunshade device according to the present invention includes a screen winder that winds and unwinds the screen at the upper outer portion of the window, and the left and right sides of the window rotate in the vertical direction with the lower end side as a fulcrum, and the upper end side is A vertical arm that is urged to rotate outward, the lower end side of the screen is connected to the upper end of the vertical arm, and the passing position at the upper part of the window of the screen that is unwound from the screen winder is outside the window It is characterized by having a screen feeding position moving means which is movable in the horizontal direction.

Here, the passage position in the upper part of the window of the screen unwound from the screen winder will be specifically described as follows.
When shielding the outside of the window with a screen,
(1) A cocoon mode in which the screen is projected from the top of the window outward.
(2) A fully-closed mode that droops like a drool from the top of the window along the outside of the window to the bottom of the window.
(3) A space mode in which a predetermined space is formed outside the window by the screen descending vertically from a position at a predetermined distance from the wall on the outside of the window.
There are at least three types of shading modes.
In this case, the difference between the fully closed mode and the space mode depends on whether the screen extension position in the upper part of the window is in the vicinity of the window or a position at a predetermined distance from the window.
Therefore, in this specification, the passing position in the upper part of the screen window means a screen passing position for switching between the fully closed mode and the space mode, and this switching is performed by the screen feeding position moving means.

  In the present invention, the screen feeding position moving means has a moving mechanism in which the screen winder itself moves in the horizontal direction, or the window upper drawing position of the screen is outside the window upper vicinity and the window upper vicinity. The feeding member may be a feeding member that moves or switches to an outer projecting position that projects to the outside, and the feeding member restricts rotation in the outer direction by a locking portion provided on the vertical arm and rotates outward. It may be connected to the upper ends of the pair of left and right biased vertical arms that are biased, and the feeding vertical arm may adopt a structure capable of restricting or releasing rotation in the outer direction by a stopper member.

In the present invention, it is possible to switch between the fully closed mode and the space mode only by switching the position of the screen winder or the position of the window upper part feeding member between the vicinity of the window and the outward protruding position. If the feeding member is connected to the upper ends of a pair of feeding vertical arms on both the left and right sides, the wrinkle angle by the screen can be adjusted only by controlling the amount of unwinding of the screen by the winder, and the feeding by the stopper member Switching between the fully closed mode and the space mode can be performed by a switching operation for locking or releasing the rotation of the vertical arm.
As a result, an awning device that is excellent in operability, simple in structure, and inexpensive can be obtained.
When the awning device is used in the space mode, it does not interfere with the screen even if the window is opened to the outside, so that light can be shielded while ensuring ventilation, and there is a feeling of opening.
Moreover, it can also be used as a space for drying laundry.

The structural example of the sunshade apparatus which concerns on Example 1 is shown. The structural example of the sunshade which concerns on Example 2 is shown. The structural example of the sunshade apparatus which concerns on Example 3 is shown. The structural example of the sunshade which concerns on Example 4 is shown. 1 is a perspective view of a sunshade device according to Embodiment 1. FIG.

  The sunshade device according to the present invention will be specifically described below based on examples, but the present invention is not limited to these examples.

FIG. 1 shows a configuration example of the sunshade device and a method for switching the use mode in the first embodiment.
FIG. 5 is a perspective view in the space mode.
Although this embodiment is an example in which a sunshade 10 is attached to a window opening in which a window 2 that opens outwardly on a wall (outer wall) 1 is formed, the window structure may be in the form of a sliding window or the like.
A roll screen winder 11 is attached to the upper part of the window, and the leading end (lower end part) 15a of the screen is connected to the upper end parts 13a of a pair of vertical arms 13 provided on the left and right sides of the window.
The winder 11 unwinds the screen, controls the winding, and adjusts the unwinding amount.
Although the vertical arm 13 is rotatable in the vertical direction around the lower end portion 13b and is not shown in the drawing, the upper end is biased in the direction of rotating outward.
The urging method may be any means such as a torsion spring, a coil spring, or a tension spring.

A pair of left and right feeding vertical arms 14 that are urged to rotate outwardly about the lower end portion 14b as an axis center are provided inside the vertical arms 13.
The feeding vertical arm 14 interferes with a locking portion 13 c provided on the vertical arm 13 and is regulated so as not to rotate outward from the vertical arm 13.
The feeding vertical arm 14 can be switched between a state in which it can be rotated only to a predetermined angle by the stopper 16 and a free state in which it is rotated downward by releasing the stopper 16.
A feeding member 12 is provided between the upper ends of the pair of feeding vertical arms 14, and the feeding position of the screen 15 at the upper part of the window is controlled by the feeding member 12.

Next, switching of the use mode will be described.
FIG. 1A shows a state in which the screen 15 is completely wound by the winder 11 and is fully opened.
When the screen 15 is unwound by a predetermined amount from this state, the vertical arm 13 is urged in the outward rotation direction as shown in FIG.
In this case, the feeding vertical arm 14 also follows the movement of the locking portion 13c and rotates outward.
When the screen 15 is further unwound, as shown in FIG. 1 (c), the vertical arm 13 is turned so that the tip 13a is on the lower side, but the feeding vertical arm 14 is stopped halfway. Since 16 is provided, the feeding member 12 is positioned above and outside the window, and a spatial mode is formed.
When the stopper 16 is released in this state, the feeding vertical arm 14 is also rotated until the distal end portion 14a is directed downward, and enters the fully closed mode as shown in FIG.

A structure according to Example 2 is shown in FIG.
The difference from the first embodiment is that the length of the vertical arm 23 is shorter than the length of the feeding vertical arm 24, and the lower end 23 b of the vertical arm 23 is pivotally supported in the middle of the feeding vertical arm 24 and the stopper 26 is The feeding vertical arm 24 has a role of maintaining the substantially vertical state or switching the rotation to a free state, and the feeding vertical arm 24 is rotated only to a predetermined angle by means different from the stopper 26 in advance. The other parts are common to the first embodiment.
FIG. 2A shows a state in which the screen 15 is completely wound up by the winder 11, which is a fully open mode of the screen.
When the screen 15 is unwound while being restricted by the stopper 26 so that the feeding vertical arm 24 is not rotated, only the vertical arm 23 is rotated as shown in FIG.
On the other hand, when the stopper 26 is released and the screen 15 is unwound by a predetermined amount, the feeding vertical arm 24 rotates around the lower end 24b while being engaged with the engaging portion 23c of the vertical arm 23 as shown in FIG. Moves to 庇 mode.
When the screen 15 is further unwound, as shown in FIG. 2 (c), since the feeding vertical arm 24 is rotated only to a predetermined angle in advance, the space mode is set.

The third embodiment is an example in the case where the collar portion 3 is previously provided on the upper portion of the window.
In this case, a pair of vertical arms 33 are urged to the left and right of the window so that the distal end portion 33a rotates outward and downward with the lower end portion 33b as an axial center.
Since the front end portion 33a of the vertical arm 33 is connected to the lower end portion of the screen, when the screen 15 is unwound as it is, the fully closed mode is set as shown in FIG.
On the other hand, the bar-shaped feeding member 32 temporarily placed by the bracket 32a in advance is moved to the bracket 32b located at the upper part of the window and outside as shown in FIG. Is regulated and becomes the spatial mode.

The fourth embodiment is an example in which the winding mechanism 11 provided in the flange portion 3 is provided with a moving mechanism 4 that switches between a window vicinity position and a protruding position.
In this way, when the screen 15 is unwound in a state 4a in which the winder 11 shown in FIG. 4A is on the window side, the fully closed mode is set as shown in FIG. As shown in c), when it moves to the protruding position 4b, it becomes a spatial mode.
