Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a sunshade device that blocks direct sunlight entering through a window by means of a movable screen on the outside of the window.

(Prior Art) Curtains that are generally installed on the indoor side of windows have the function of blocking direct sunlight, but the entire window frame and the curtains themselves are exposed to sunlight and heat up, causing the room temperature to rise due to the hot air. There was a problem in that the room was hot, especially in the summer, and even if the air conditioner was used, its effectiveness would be reduced.

Therefore, attempts have been made to attach a roll-up type sunshade screen using a motor or the like to the outdoor side of the window to block sunlight on the outdoor side and thereby prevent hot air from accumulating inside the window frame. However, this type of conventional sunshade screen has a structure in which the entire structure, including the winding mechanism, is attached to the exterior wall of the building, which requires time and effort to install, makes the exterior appearance of the building unsightly, and is difficult to install in high places higher than the second floor. Some windows were particularly difficult to install, and the sun screen was not easily removed for cleaning or washing.

(Problems to be solved by the invention) This invention attempts to solve the above-mentioned conventional problems.The entire sunshade screen, including the winding mechanism, can be installed from indoors, and can be installed in high places higher than the second floor. It is an object of the present invention to provide a window sunshading device which can be easily installed and the screen can be easily attached and detached, and which does not spoil the external appearance of a building.

(Means for Solving the Problems) For the purpose mentioned above, the window sunshade device according to this invention has a hollow blind that can be opened to the indoor side at the top of the window frame, and a hollow blind that can be opened to the indoor side on the left and right sides of the window frame. A vertical guide groove is formed which opens toward the center of the window and whose upper end communicates with the inside of the window, and a roll that is rotated in the circumferential direction by a built-in motor is installed inside the window.
A protruding shaft protruding from one end of the roll is fitted and locked into a locking hole of a spherical shaft rotatably supported by a ball bearing provided on one vertical frame of the window, and a motor provided at the other end is engaged. The base is fixed to the other vertical frame of the window, so that it is installed horizontally, and the roll is wrapped with a sunshade screen that moves up and down along the guide groove as the roll rotates.

(Example) This invention will be explained below based on the illustrated example.

In the figure, 1 is a window frame made of aluminum or an extruded material thereof, in which sliding shoji 2, 2 are fitted so as to be horizontally movable along upper and lower rail frames 1a, 1b, and the upper rail frame 1a and mounting Upper frame 1
A hollow nomoku 3 is formed between it and c. The outdoor side of this mumu 3 is sealed with an outdoor cover 3a made of aluminum, stainless steel, etc., and the indoor side is sealed with an indoor cover 3b made of the same material and having a U-shaped vertical section. Fixed. Further, on the outdoor sides of the left and right vertical frames 1d and 1e of the window frame 1, guide frame members 5 and 5 each having a substantially U-shaped cross section are fixed to the lower portions of the blinds 3. Vertical guide grooves 6, 6 open to the window center side are formed, and the upper end of each guide groove 6 communicates with the inside of the blind 3. 7 is an angle material fixed to the entire inner circumference of the window opening room of the building frame 8, 9
are the lower rail frame 1b of the window frame 1, the upper mounting frame 1c,
Mounting brackets for fixing the left and right vertical frames 1d and 1e to the angle member 7; 10 is a bar interposed between the angle member 7 and the mounting bracket 9 and welded together; 11 is a bar extending all around the inside of the window opening room; A decorative picture frame,
Reference numeral 12 designates an interior decorative board, and reference numeral 13 designates a caulking material for sealing the outdoor gap between the outer periphery of the window frame 1 and the frame 8.

A roll 14 that rotates in the circumferential direction by a built-in motor (not shown) is installed in the window 3 so that its axial direction is horizontal, and as shown in FIG. It is attached to a nearby indoor wall. As shown in FIG. 5, the roll 14 has an end plate 16 integrally fixed to one end of a cylinder 14a made of aluminum or the like and having a protruding shaft portion 16a.
A non-rotating motor base 17 protrudes from the other end of the cylinder 14a, and a mounting plate 18 is attached to the motor base 17.
is fixed. On the other hand, a ball bearing 19 that rotatably holds a ball shaft 19a is fixed to the right vertical frame 1d of the window frame 1 at a portion located on the inner surface of the blind 13 via a screw 20a, and the same portion of the left vertical frame 1e. As shown in FIG. 4, L-shaped mounting brackets 21 are fixed at two locations on the top and bottom near the outdoors. As shown in FIG. 2, the roll 14 is inserted into the circular hole provided in the ball shaft 19a of the ball bearing 19 with the protruding shaft portion 16a of the end plate 16 removed, with the outdoor cover 3b of the open end plate 3 removed. 19b, and then attach the ear-shaped mounting protrusions 18a and 18b provided at the top and bottom of the mounting plate 18 to the L-shaped mounting bracket 2.
1 and 21 and screwing the two together with screws 20b and 20b, it can be easily installed in the nozzle 3, and can be easily removed by performing the reverse operation.

A sunshade screen 22 made of cloth, synthetic resin, etc. and having a sunlight-blocking property is wound around this roll 14 with its end fixed. A flat cylindrical weight 23 made of aluminum or the like and having a length spanning the entire width of the screen 22 is fixed to the tip of the screen 22, and a strip-shaped guide made of stainless steel or the like is fitted onto this weight 23. Both of the protruding ends of the plate 24 are positioned to protrude into the guide grooves 6, 6. Therefore, by rotating the roll 14 in one direction, the sunshade screen 22 descends along both guide grooves 6, 6, shielding the window from the outside and preventing sunlight from entering the room. By rotating the roll 14 in the opposite direction, the sunshade screen 22 is raised and the above-mentioned shielding state is released. The upper and lower limit positions of the sunshade screen 21 are automatically set by a limit switch (not shown), and can be adjusted by limit switch adjusting screws 17a and 17b provided on the motor base 17, as shown in FIG. It is.

In the above embodiment, the rotating end of the roll 14 is fitted into the spherical shaft 19a and the fixed end is secured with screws to facilitate attachment and detachment.
In this invention, the mounting structure of the roll 14 can be modified in various ways other than those described above.

(Effects unique to the invention) According to this invention, the protruding shaft protruding from one end of the roll from the indoor side is fitted into the engagement hole of the rotatable spherical shaft of the ball bearing provided on one vertical frame of the window. After that, simply attach the motor base on the other end to the other vertical frame of the window, and the roll can be easily installed inside the window, and by reversing the procedure, you can easily install the roll from inside the window. This allows maintenance work such as replacing the sunshade screen to be performed quickly and easily.

Further, since the roll is fixedly supported by both window vertical frames, the roll can be rotated quietly by the built-in motor, and the sunshade screen can be smoothly raised and lowered.

Moreover, since the roll is stored in the opening at the top of the window frame, it does not damage the exterior of the building, and since the sunshade screen moves up and down along the guide grooves on both sides, its operation is reliable and it is protected from the wind. A constant cut-off state can be maintained without being agitated.
