The present invention relates to the imparting of functionality to windows, and in particular to a composite functional film internal window system in which functional glass films, sheets and panels, such as light-emitting films, light-dimming films, solar photovoltaic films, heat-generating films, heat-shielding and heat-insulating films, electromagnetic wave shielding films, visual displays, visual monitors or visual screens and so on are imparted to windows using an electrically conductive film holding frame without glass replacement or direct application to the glass.
In general, the windows of houses, buildings, and other structures are illuminated by installing transparent glass, but since ordinary glass does not functionally block light, it can be said that sunlight, including ultraviolet to infrared rays, is generally allowed to pass through. However, if light is collected without shielding from infrared rays, the indoor temperature rises too high in summer. In addition, direct exposure to ultraviolet rays can damage the skin or the like and deteriorate indoor items. There is also the problem of heat escaping from the indoor side through the glass windows in winter.
From the viewpoint of protecting against the harmful effects of such general glass collection, technologies for functional light shielding have been developed in recent years. In addition to curtains made of functional fabrics, installing shielding boards and so on, the most common method is to use functional films that block certain rays of light and attach them to the window glass.
In other words, it is a method of attaching functional films such as light-dimming film, heat shielding film, heat insulating film, ultraviolet UV shielding film, heat-generating film, solar photovoltaic film, and in addition, visual screens for special purposes to glass windows by limiting the wavelength of sunlight transmission.
In the description of the present invention, these functional films such as light-dimming film, heat shielding film, heat insulating film, ultraviolet UV shielding film, heat-generating film, solar photovoltaic film, electromagnetic wave shielding film and so on, as well as visual screens that serve special purposes and panels with the same functions are collectively referred to as “functional film sheets and panels”.
Various methods of using functional film sheets and panels without directly attaching them to window glass have also been devised and introduced in the literature. This will be described in the following Patent Documents 1 and 2.
For example, in Patent Document 1, a technical concept of the device and method is disclosed, wherein a sealed window or door with two effects of heat insulation and shading is realized by covering a frame (often made of wood) in the opening of a building (sash window, door and so on) with a resilient film (transparent or colored, as used in sun visors, file cases, —P-V-C, etc.), or by directly fixing a winding device or an extendable winding device, which is made of a film with cloth, paper, or other similar material fastened or laminated to a stick at the top or bottom, right or left, in a position that allows some space between it and the existing window glass or door, and moving the handle with the film with Velcro (registered trademark) attached thereto, up and down or left and right along the guide rails on the left and right or up and down, and if necessary, along the guide rails installed in between, fixing, with retractable Velcro (registered trademark) and so on, and attaching it to the frame opposite to the frame with the winder.
However, in this example, the function of the film is only specified as shading and heat insulation, and there is no detailed specification of the material, function and its effect. In addition, the method of attaching and fixing the film is technically inexperienced, and the tension of the film can be said to be not as high as that of a cloth curtain. In addition, the fixing method is simple, and there is no technology to avoid the danger of falling, making it largely impractical.
And in Patent Document 2, a rubber magnet is attached to the perimeter of the window main body via double-sided tape. Next, attach double-sided tape around the heat insulating material as well, and attach a rubber magnet on top of it. The technical concept of the window and frame, in which the heat insulating material made as described above is adsorbed to the main body through the force of a magnet, is disclosed.
However, even in this example, the technology is childish, such as attaching the heat insulating material via a magnet attached to the wall, and there is no description or mention of technology to avoid the danger of falling damage, and it must be said that the technology is greatly lacking in implementation requirements and practicality.
In addition, in the above-mentioned Patent Documents 1 and 2, the main purpose remains in the method of providing shading and heat insulation functions, and has not led to a window system that integrates more than one function. The technology of films, panels, and screens that function by energizing has also not yet been disclosed.
Since there are many issues that have not been resolved by the previous technologies or technical ideas as described above, it have not yet been achieved to install functional film sheets and panels on windows with special purposes or special functions such as light-dimming film, heat shielding film, heat insulating film, ultraviolet UV shielding film, heat-generating film, solar photovoltaic film, electromagnetic wave shielding film, and other functional film sheets and visual screens with special applications or special functions, as well as panels with the above functions.
In the past, in order to add the above functions to glass windows, one method was to replace the glass with functional glass in which functional film is laminated inside the glass, and the other method was to apply functional film sheets directly to the glass.
However, in the installation of functional glass and functional film sheets on window glass, there are issues regarding how to replace the functional glass and how to attach it directly to the glass, as described below. In other words, replacing existing glass with glass processed with light-dimming film, solar photovoltaic film, or visual screen requires significant cost and long construction period.
In addition, when light-dimming film, solar photovoltaic film, or visual screens are applied to glass, it is necessary to remove the existing film when renewing or removing each film, and the use of scrapers as removal tools may scratch the glass.
In rental buildings and houses, the film is applied at the expense of the tenant, and when the film is removed and the glass is damaged, the tenant is required by the landlord to replace the damaged glass, and thus bears the burden of compensation. In the case of landlord-ownership, it is the landlord's responsibility, and it goes without saying that the landlord does not like to bear the burden. The same problem exists when the film is renewed and removed, as the existing film needs to be removed.
Nowadays, existing glass may have glass shatterproof film attached to it. Assuming this, when applying light-dimming film, solar photovoltaic film, or visual screen to glass, it is necessary to remove the existing glass shatterproof film, and the same as above, there is a large possibility of damaging the existing glass. Applying light-dimming film, solar photovoltaic film, or visual screens to damaged glass may degrade the performance and durability of the various films. In addition, it may not be possible to attach it.
The present invention is intended to solve the problems of the conventional technology and to expand the market of functional film sheets and panels. It is aimed to ensure the safety of the main body glass window, and at the same time, demonstrate sufficiently various functions and usages of the functional film sheets and panels, and improve remarkably the workability of the installation of the glass window, and provide a film internal window system with composite functions such as light emission, light dimming, heat shielding, heat insulating, ultraviolet UV shielding, heat generation, solar power generation, electromagnetic wave shielding, visual display function, visual monitor function, or visual screen function and so on, which can significantly improve the workability of installation on glass windows and economic efficiency.
To solve the problems, the composite functional film internal window system according to the present invention is characterized in being a window frame for holding film sheets and/or panels with functions of light emission, light dimming, heat shielding, heat insulating, ultraviolet UV shielding, heat generation, solar power generation, electromagnetic wave shielding, visual display function, visual monitor function or visual screen function or the like, as one single laminated layer, wherein the window frame is a window frame installed near an upper side and/or lower side and/or right side and/or left side of a glass window; and a laminating and holding structure of the window frame is a structure in which each of the film sheets and panels is separately sandwiched and fixed in place on a surface and held via insulating spacer sections between the upper side and/or lower side and/or right side and/or left side of a plurality of the film sheets and panels having the composite functions.
That is, the composite functional film internal window system according to the present invention is a frame of the internal window formed near the outer circumference of the four sides of a window whose window frame is of various shapes and sizes, and the frame is not limited to the four sides of the window that are connected in a square shape, but can be a frame that forms three or two sides of the window, or even one side.
Film sheets or panels with various functions are sandwiched between those internal window frame bodies via insulating spacers. The various functions refer to light emission, light dimming, heat shielding, heat insulating, ultraviolet UV shielding, heat generation, solar power generation, electromagnetic wave shielding, visual display function, visual monitor function or visual screen function and so on. These functional film sheets and panels are fixed in a state where in a well-tensioned state in four directions, three directions, two directions, or one direction, with the composite functional film internal window frame according to the present invention.
Then, the composite functional film internal window system according to the present invention is characterized in including a conductive terminal in the insulating spacer sections for holding the laminating and holding structure of the window frame in place on a surface, wherein each of the film sheets and the panels respectively has a conductive function with outside.
Some functional film sheets and panels require conductive functions, and the insulating spacers have conductive terminals to connect these conductive circuits to the outside. The invention does not limit the position, size, or material of forming the conductive terminals. The position, size, and material of these conductive terminals should be selected according to the optimal specifications of the functional film sheet and panel. Also, the number of layers of functional film sheets can also be freely set.
It is possible to hold an aspect wherein a circumferential section of the window frame has a gasket fixing structure made of flexible resin, and the gasket fixing structure is connected and fixed to a wall and/or wire and/or pigeonhole structure outside the window frame to maintain tension strength (tension) of the film sheets and panels.
In other words, the composite functional film internal window frame according to the present invention is only a frame, so it has a mechanism to be fixed to the window frame or wall of conventional installation near the glass window as described above. However, these fixing methods can be selected in a variety of ways within the scope of conventional technology, and the technical concept of the present invention encompasses these selection technologies.
In the composite functional film internal window system of the present invention, it can be an aspect wherein a structure of a corner section of the window frame is an L-shaped frame structure section, and a connecting section of the L-shaped frame structure section and the window frame are each fitted with an concavo-convex structure, and power terminals of the insulating spacer sections of the film sheets and the panels are each individually laminated inside the L-shaped frame structure section and electrically connected to the power terminals of the respective insulating spacer sections.
When the composite functional film internal window frame according to the present invention is shaped to connect the four sides of the frame, top, bottom, left and right, it goes without saying that the formation of the frame can be simplified by using an concavo-convex insert shape at the corner sections. It is also possible to have conductive terminals on each of the split frames.
It is possible to be an aspect wherein the composite functional film internal window system of the present invention can also take the condition wherein the upper side or lower side or right side or left side of the window frame is a film sheet and panel storage section where the film sheets and panels are wound and stored via spring force.
Since the functional film sheets and panels to be sandwiched in the composite functional film internal window system according to the present invention are often film-like and flexible, they can be wound and stored, and the film sheet storage section and panel storage section, which are wound and stored via spring force using conventional technology, allow for simple storage and movement.
In addition, it is possible to be an aspect wherein the composite functional film internal window system of the present invention can be a structure in which right and left sides of the window frame are connected and fixed to a support with casters at underfoot sections, and can be moved via the casters.
By coupling the support section with casters to the composite functional film internal window frame according to the present invention, the composite functional film internal window system according to the present invention can be easily moved from one glass window to the next glass window and from one room to the glass window of the next room. It will be possible to provide a composite functional glass window frame system that can be moved and installed as needed.
In addition, it can be a form with an additional function wherein the composite functional film internal window system of the present invention, comprising: a U-shaped upper receiving frame sandwiched in a manner that the window frame is sandwiched between the upper section of the window frame and the upper wall; a spring structure body sandwiched in a manner that the upper section of the window frame is depressed between the upper section of the window frame and the upper receiving frame; and a U-shaped lower receiving frame sandwiched in a manner that the window frame is sandwiched between the lower section of the window frame and the lower wall, wherein the window frame is held firmly without a gap in an up-down direction of the window frame. (Refer to

Spring structure body may use, for example, a plate spring or the like. The present invention does not limit the material of the spring structure body or an individual structure.
In other words, the above mechanism also has the function of shielding and preventing the air on the window side, which is the back side of the composite functional film internal window system according to the present invention, from flowing into the room, which is the front side of the same internal window system. Details are described in the detailed description of embodiments of the invention.
In addition, the above-mentioned U-shaped upper and lower receiving frames can be firmly fixed by simply inserting the main body (window frame) of the internal window system from top to bottom by installing the upper and lower receiving frames on the upper and lower walls first when installing the main body (window frame) of the composite functional film internal window system of the present invention, which has the effect of simplifying construction and greatly improving workability.
It can be an aspect where the composite functional film internal window system according to the present invention can also comprise a plurality of thin rectangular plate shaped gap sealing functional materials that are fixed through the receiving grooves formed in the upper and/or lower receiving frame, and cover the space between the left horizontal frame and the wall and the right horizontal frame and the wall of the window frame, sealing the gap in the left and right directions of the window frame and shielding the air movement in the back and front of the window frame. (Refer to
A thin rectangular plate of gap sealing functional material, such as rubber-based sealing material, has the function of shielding the gap between the left and right walls of the main body (window frame) of the composite functional film internal window system according to the present invention. This function will also have the function of shielding and preventing air from the window side, which is the back side of the composite functional film internal window system, from flowing into the room, which is the front side of the same internal window system according to the present invention.
