Description

BACKGROUND OF THE INVENTION

Field of Invention

The present invention relates to the technical field of building materials, in particular, to an integrated window with energy saving, sun shading, heat insulating and heat preserving functions.

Related Art

The energy consumption of buildings now accounts for around 30% of the total energy consumption of the whole country with development of economy, of which the energy consumed by air conditioners account for around fifty percent. It is one of the most direct and effective energy saving means to provide the buildings with sunshades. However, sun-shading products are mounted so separately from the windows of buildings presently in this country that materials are wasted for repeated installation even though the energy saving effect could be achieved to some extent.

To this end, an integrally welding window frame profile for a single sliding window is disclosed in the Chinese Patent Publication No. CN101787836A, comprising a frame profile, a muntin frame profile, a small muntin profile and a sealing strip, in which a profile facade is provided at the frame profile and the muntin frame profile and small and medium-scale profiles are welded to the profile facades; a fundamental chute is positioned on the frame profile and the muntin frame profile, and the fundamental chute is connected with the chute heightening strip and the chute sealing strip in sequence; the sealing strip is provided with adhesive tape and wool top openings; and the adhesive tape opening is connected with screen window cloth having an adhesive tape. Even though the components for mounting the sliding window and those for mounting the curtain cloth are combined with each other to some extent in said window frame profile, the window frame profile has a large number of parts and a complicated structure and could not be conveniently mounted. Moreover, the position for mounting the window cover is only set on one surface of said window frame and the sun-shading effect could only be achieved in one single direction. If the user has to simultaneously mount indoor and outdoor sun-shading and mosquito proof curtain cloth, an additional mosquito proof curtain has to be mounted in an indoor position. As such, the problem for repetitive mounting still exits in the window frame, and the materials and human resources are wasted. In the meantime, the window frame formed by using said window frame profile still has a poor windproof property.

In conclusion, the conventional windows have such disadvantages that the outer windows are constructed by glass windows, which could permit daylight to pass through and control the flow of air into and out of rooms, but do not have the sun-shading or heat preserving function. Therefore, the user must additionally mount various sun-shading shades, covers and canopies outside of the windows, and mount various curtains within the room, which thus brings about double constructions. The existing windows have a complicated window structure and require time, labor and cost consuming double constructions.

The energy saving, sun shading, heat insulating and heat preserving integrated multi-function window of the invention has the following technical effects.

Firstly, the existing windows are simplified by the invention. According to the invention, revolutionary improvements have been made to conventional outer windows to organically integrate the energy saving, sun shading, heat insulating and heat preserving outdoor sun shading curtains, glass windows and indoor windows into one piece. Therefore, a multi-function constructive window will be formed and windproof devices can be disposed on both vertical edges of the window frames.

Secondly, the window of the invention has a number of functions. It is widely known that outdoor sun-shading curtains and indoor curtains are additionally mounted on the outer windows to efficiently reduce heat radiation of sunshine entering into rooms and outflow of indoor heat. With the development of human demands and technological levels, in order to prevent the sun-shading curtains or ordinary curtains drifting because of the wind, the designers have made several tries but have not obtained ideal results.

However, the present invention has organically combined translative windows, outdoor sun-shading curtains and indoor curtains together to form a new outer window. The functions of translative windows, outdoor sun-shading curtains and indoor curtains are incorporated into one single window. The benefits of translative windows, outdoor sun-shading curtains and indoor curtains can be obtained by one single window of the invention. Therefore, a large amount of raw materials can be saved and the cost of materials can be reduced. In order to improve the windproof performance of the outdoor sun shading curtains and indoor curtains, windproof components are additionally provided within the vertical edges of the integrated window frames in the invention. The windproof mechanism formed as such can efficiently overcome the drifting of the curtain cloth because of the wind pressure.

Thirdly, the materials can be saved and the cost can be reduced. If the functions of the window of the invention are to be obtained in the prior art, sun shading curtains have to be made and mounted outside of the outer windows, curtains have to be made and mounted inside of the outer windows, and outer windows have to be made and mounted when the house is built, for which three process have to be fulfilled. On the other hand, the window of the invention can be mounted at one time when the house is to be built. As such, not only the production cost is reduced, but also the construction times are decreased. Therefore, the construction process is expedited and the cost for mounting and construction is reduced.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention will be described in detail below with reference to the drawings, and the technical solutions of the invention will be further illustrated. However, the scope of the invention is not limited to these embodiments.

First Embodiment

In this embodiment, an integrated window has front and back window frames, as shown in FIGS. 1-12. The front and back window frames have the same structural principle, for which the structures of the window frames will be specifically described as follows.

Two front frame bodies 2 are symmetrically located on both sides of the front window frame. The front frame body 2 has a front support portion 2a and a front guide portion 2b. The front frame body is configured as an elongated L-shape. That is to say, the front support portion 2a is vertically connected with the front guide portion 2b, and an indentation 2e is formed above the front support portion 2a and the front guide portion 2b, in which the upper end of the front support portion is located higher than the front guide portion. In this embodiment, the front support portion 2a is integrated with the front guide portion 2b.

A front window cover 1 is mounted on the front frame bodies 2. The indentation 2e formed between the front guide portion 2b and the front support portion 2a has a width identical to that of the window cover. In the process of mounting, the front window cover is fixed at the said front indentation 2e, so that the front window cover 1 will not be lonely exposed and projected to the external environment. As such, the front portion of the window, i.e. the portion exposed at the external wall, is configured as a square shape, which provides the window with an overall attractive appearance.

An upper slide 9 is provided between the upper ends of the support portions of the front frame bodies on both sides, and a lower slide 10 is provided between the lower ends thereof. The upper and lower slides are provided with corresponding slide ways, which are mainly used to facilitate horizontal movement of the sliding window between left and right. The bottom surface of the lower slide 10 is covered by the outer window frame sealing plate 23.

Two back frame bodies 3 are symmetrically located on both sides of the back window frame. The back frame body 3 has a back support portion 3a and a back guide portion 3b. The back frame body is configured as an elongated L-shape. That is to say, the back support portion 3a is vertically connected with the back guide portion 3b, and an indentation 3e is formed above the front support portion 3a and the front guide portion 23b, in which the upper end of the back support portion is located higher than the back guide portion. In this embodiment, the back support portion 3a is integrated with the back guide portion 3b.

A back window cover 17 is mounted on the back frame bodies 3. The indentation 3e formed between the back guide portion 3b and the back support portion 3a has a width smaller than that of the back window cover 17. As the back frame bodies 3 are faced to the interior of the room, the back frame bodies 3 can not extend out of the wall for the purpose of attraction and harmony of the whole product. The back window cover 17 shall have a relatively large area because a tubular motor 11 has to be mounted within the back window cover 17. Therefore, the width of the indentation 3e formed between the back guide portion 3b and the back support portion 3a is configured to be smaller than the width of the back window cover 17 in the back frame bodies 3, so that the back window cover 17 could individually extend beyond the wall.

An upper slide 9 is provided between the upper ends of the support portions of the back frame bodies on both sides, and a lower slide 10 is provided between the lower ends thereof. The upper and lower slides are provided with corresponding slide ways, which are mainly used to facilitate horizontal movement of the sliding window between left and right. The bottom surface of the lower slide 10 is covered by the inner window frame sealing plate 24.

In this embodiment both the front window cover 1 and the back window cover 17 are respectively fixed to the upper part of the front frame bodies and the lower part of the back frame bodies by bolts.

The front support portion 2a is fixedly connected with the back support portion 3a by means of a plastic bar 5. In particular, a first groove 2c is set on one side of the front support portion 2a and a second groove 3c is set on one side of the back support portion 3a corresponding to the first groove 2c. Two long lateral edges of the plastic bar are respectively inserted into and fixed to the first groove 2c and the second groove 3c. The plastic bar 5 has an I-shape section. In the process of mounting, the front frame body 2 is firstly aligned with the back frame body 3, the plastic bar 5 is then aligned with and inserted into the first groove 2c and second groove 3c, and two long lateral edges of the plastic bar 5 are fixed within the first groove 2c and second groove 3c to connect the front frame body 2 with the back frame body 3. As such, the front frame bodies 2 can be readily mounted to the back frame bodies 3. The window frames are integrally made from aluminum alloy materials. The front support portions 2a of the front frame bodies 2 and the back support portions 3a of the back frame bodies 3 are made of hollow plates that are transversely and circumferentially closed and have openings at both longitudinal ends. As such, on the one hand, the reliability of the whole product could be guaranteed; and on the other hand, not only the production cost could be saved, but also good heat insulating performance could be obtained.

When the front and back window frames are connected by using the plastic bars, the corresponding upper and lower slides thereof are fixedly connected with each other as well. Particularly, said two upper slides are connected via a plastic bar which is heat insulating, and said two lower slides are connected via another plastic bar which is heat insulating.

A front frame body limiting element 2d is located on the inner side of one of the front support portions 2a for positioning the sliding window, and a back frame body limiting element 3d is located on the inner side of the back support portion 3a on the opposite side for positioning another sliding window. As such, the sliding windows could be conveniently mounted and positioned by using said two limiting elements.

Each of the front window cover 1 and the back window cover 17 has a curtain cloth rolling mechanism located therein. In this embodiment, each of the curtain cloth rolling mechanisms has a tubular motor 11 mounted within the aluminum-made reel pipe 16. The upper edges of the said both pieces of curtain cloth 4 are respectively fixedly connected to the wall of the corresponding aluminum pipes 16. The curtain cloth 4 is wound around the outer surface of the aluminum pipe 16. This way, the reel pipes 16 could be driven to rotate by actuating the tubular motors 11 to automatically move the curtain cloth 4 up and down, so that the curtain cloth 4 is unwound or wound.

End caps 12 are provided on both ends of the front and back window covers and are rotatably matched with the reel pipe 16. Extension elements 12b are provided on the end caps 12. The end caps 12 could be fixedly connected with the window frame support portions by inserting the extension elements 12b into the window frame support portions. As such, the overall reliability of the curtain could be guaranteed. The curtain cloth 4 mounted on the front window cover 1 which is located on the exterior wall, is made from sun-shading materials, and the curtain cloth 4 mounted on the back window cover 17 which is located within the room, is made from screen window cloth. Therefore, the said two pieces of curtain cloth 4 could be respectively pulled down as required, which could respectively act to prevent sunshine entering into the room and shield mosquitoes and wind. Heat dissipation holes could be provided on the end caps 12.

Each of the front guide portions 2b of the front frame bodies 2 and the back guide portions 3b of the back frame bodies 3 has a track 7 located therein. In particular, the track 7 is integrated with the corresponding guide portion to facilitate the manufacturing process. A longitudinal opening is located on the side of the guide portion 2b facing the curtain cloth 4. The track 7 forms an open slot in the longitudinal direction and the opening of the open slot faces to one side of the curtain cloth 4. The upper opening of the open slot is in communication with the window cover 1. A guide rod 7 is located within the open slot in the longitudinal direction. Two symmetrically disposed seal plugs 8 are mounted within the front guide portion 2b and the back guide portion 3b adjacent to the end of the track 7. A gap 8a is formed between said two seal plugs 8 and has a diameter smaller than the outer diameter of the guide rod 6. Both lateral edges of the curtain cloth 4 respectively pass through the longitudinal opening of the guide portion 2b and the opening of the open slot on the same side, to extend into the open slot 21 and be transversely positioned at the guide rod 6.

Both lateral edges of said two pieces of window cloth 4 are fixedly connected with a hem 4a which passes through the gap 8a between two seal plugs 8 to be covered on the guide rod 6 and moves up and down along the guide rod 6. The hems 4a are cloth made from ordinary nylon composite materials or ordinary chemical fiber materials, have a tensible feature and thus tend not to be broken. The hems 4a can be folded in two to form a circumferentially closed space into which the guide rod 6 is inserted, so that the guide rod 6 is connected with the curtain cloth 4. While the hem 4a is wound up with the curtain cloth 4, the hem 4a is flattened, has a thickness identical to that of the curtain cloth 4 and constantly remains flat to prevent the window cloth 4 from being displaced. As such, when the wind blows to the window cloth 4, the curtain cloth 4 is caught by two guide rods 6 through the hems 4a and is pulled straight, which ensures the guide rod 6 be always restricted within the track 7 to prevent from being removed. The curtain cloth 4 and the hems 4a can be welded together by using a heat sealing device under the temperature of 200-400° C. or sewed to each other by using a sewing machine.

A bottom plug 13 is mounted at the lower end face of the window frame guide portion and a guide plug 14 is mounted at the upper end face of the guide portion. A positioning element 15 is mounted within the bottom plug 13. One end of the guide rod 6 is inserted into the positioning element 15 and the other end thereof passes through the guide plug 14. The impurities, such as dust, will be prevented from entering into the window frame guide portion by the bottom plug 13 and guide plug 14. The track 7 within the window frame guide portion will be kept tidy to prevent too many impurities blocking the track 7 to make it difficult to move the curtain cloth 4 up and down.

An elliptical groove 15a is disposed on the positioning element 1. The guide rod 6 is inserted into the elliptical groove 15a. The distance between said two guide rods 6 can be varied by locating the guide rods 6 in different positions within the elliptical groove 15a, so that curtain cloth 4 of different widths can be mounted. Meanwhile, when the wind is strong, the movement of said two guide rods 6 within the corresponding elliptical grooves 15a ensures that the curtain cloth 4 can be smoothly moved. The curtain cloth 4 can be slightly and appropriately projected to prevent itself from being torn down by wind for over-straightening reasons.

The lower edge of the curtain cloth is connected with a lower rod 20. After passing through the longitudinal opening of the guide portion and the opening of the open slot on the same side, both ends of the lower rod 20 slidably extend into the open slot. The length of the lower rod 20 coincides with the distance between the guide rods on both sides. The lower rod is hollow and both ends thereof are sealed by a rod plug 2 respectively. A rubber strip 21 is mounted on the lower surface of the lower rod 20 along its length. A concave slot is formed on the lower surface of the lower rod 20 along its length. The slot is embedded into the rubber strip 21 and the rubber strip 21 partially projects from the lower surface of the lower rod 20.

Second Embodiment

This embodiment is different from the first embodiment in that one of the window frames does not have window covers, curtain cloth or other parts. The structure of the second embodiment will be described below.

As shown in FIGS. 13-17, the support portion 2a is fixedly connected with a lateral seal via a plastic bar 5. In particular, a first groove 2d is provided on a side of the support portion 2a and a second groove 4a is provided on a side of the lateral seal 4 corresponding to the first groove 2d. Both ends of the plastic bar 5 are inserted into and fixed to the first groove 2d and the second groove 4a respectively. The plastic bar 5 has an I-shape section. In the process of mounting, the lateral seal 4 is firstly aligned with the frame body 2, the plastic bar 5 is then aligned with and inserted into the first groove 2d and second groove 4a, and two long lateral edges of the plastic bar 5 are fixed within the first groove 2d and second groove 4a respectively to connect the lateral seal 4 with the frame body 2, in which case the lateral seal is conveniently mounted to the frame body. Both the window frames and the lateral seals are made from aluminum alloy materials. The front support portions 2a of the frame bodies 2 and the lateral seals are made of hollow plates that are transversely and circumferentially closed and have openings at both longitudinal ends. As such, on the one hand, the reliability of the whole product could be guaranteed; and on the other hand, not only the production cost could be saved, but also good heat insulating performance could be obtained.

A lateral seal limiting element 4b is located on the inner side of one of the lateral seals 4 for positioning the sliding window, and a frame body limiting element 2e is located on the inner side of the support portion 2a of the frame body 2 on the opposite side for positioning another sliding window. As such, the sliding windows could be conveniently mounted and positioned by using said two limiting elements.

An upper slide 9 is provided between the upper ends of the lateral seals on both sides, and a lower slide 10 is provided between the lower ends thereof. The upper and lower slides are provided with corresponding slide ways, which are mainly used to facilitate horizontal movement of the sliding window between left and right.

When the window frames are connected with the lateral seals by using the plastic bars, the corresponding upper and lower slides thereof are fixedly connected with each others as well. Particularly, said two upper slides are connected via a plastic bar which is heat insulating, and said two lower slides are connected via another plastic bar which is heat insulating.

In this embodiment, the window frame having the window cover is mainly applied to outer sun-shading windows, and thus the lateral seal 4 is located within the room and the frame body 2 is located outside of the room. In other words, the window cover 1 is positioned out of the room.

The curtain cloth 7 is made from sun shading materials, in which case sunshine can be effectively prevented from entering the room when the curtain cloth 7 is pulled down.

The other aspects of the second embodiment could refer to those described in the first embodiment.

Third Embodiment

As shown in FIGS. 18 and 19, the structures and principles of the third embodiment are substantially the same as those of the second embodiment. The third embodiment is merely different from the second embodiment in that the indentation 3 formed between the guide portion 2b and the support portion 2a has a width smaller than that of the window cover 1, because the window frame of this embodiment is mainly applied to inner sun shading windows and the frame body 2 is located within the room and the lateral seal is located outside of the room. In other words, the window cover 1 is positioned inside the room in the third embodiment. As the lateral seals 4 and the frame bodies 2 are mounted within the wall, the frame bodies 2 can not extend beyond the wall for the purpose of attraction and harmony of the whole product. Meanwhile, the area of the window cover 1 can not be overly small as it is provided with a tubular motor. Consequently, the width of the indentation 3 formed between the guide portion 2b and the support portion 2a must be smaller than the width of the window cover 1, so that the window cover 1 individually extends beyond the wall. In the meantime, in order to prevent mosquito entering into the room when the window is opened to circulate the air, the window cloth 7 is made from screen window cloth in this embodiment.

The other aspects of the third embodiment could refer to those described in the second embodiment.

Fourth Embodiment

The fourth embodiment is different from the first, second or third embodiment in that the windproof component of the window frames employs different positioning elements. In particular, the positioning element of the fourth embodiment is implemented by a flexible tape. Both lateral edges of the curtain cloth are respectively fixedly connected with the flexible tape on the same side or both lateral edges are respectively covered on the exterior of the flexible tape on the same side, and the upper end of the flexible tape is wound around the reel pipe. A hook is provided on the bottom plug at the lower end of the guide portion. When the curtain cloth is unwound, the lower end of the flexible tape is engaged with the hook of the bottom plug to keep the curtain cloth constantly in the straightened condition. When the lower end of the flexible tape is disengaged from the hook of the bottom plug, the curtain cloth could be driven by the reel pipe to wind upwards.

The other aspects of the third embodiment could refer to those described in the first, second or third embodiment.

Fifth Embodiment

The fifth embodiment is different from the first, second, third or fourth embodiment in that the reel pipe is driven in a different manner. In particular, a rope is manually pulled to drive the curtain cloth instead of the aforesaid driving components, for example the tubular motor. In this embodiment, a bead plate is externally secured to one end of the reel pipe and is driven to rotate by a pull bead, thereby driving the reel pipe to rotate synchronously.

Sixth Embodiment

The sixth embodiment is different from the first, second, third or fourth embodiment in that the reel pipe is driven in a different manner. In particular, a rocker is manually turned to drive the curtain cloth instead of the aforesaid driving components, for example the tubular motor. The driving mode by manually turning the rocker is well known to persons having ordinary skills in the art and thus is omitted herein for brevity.

The other aspects of the third embodiment could refer to those described in the first, second, third or fourth embodiment.

The present invention has the following advantages over the prior art:

1. The front and back window covers are provided with curtain cloth, which meets the demand for sun shading outside of windows and the purpose for prevention of mosquito and sun shading. As such, the curtain cloth could be of multiple uses, meet multiple demands and have cost efficiency.

2. The present invention has a more reasonable configuration, in which the guide portion for positioning the guide rod to guide the curtain cloth to move up and down is integrated with the support portion for locating the sliding window. In addition, the front frame body and back frame body respectively provided with sliding windows are connected with each other via the plastic bars. As such, good heat insulating performance could be achieved and the window could be conveniently manufactured and mounted in the invention.

3. The window frames are made from aluminum alloy and/or plastic steel materials and have a long use life.

4. The position and connection of the front frame body relative to the back frame body could be modified as required by actual circumstances. As such, the window frames could be classified into inner sun shading window frames and outer sun shading window frames, for which the window frames could be widely employed.

5. When the wind is strong, the guide rods can be located and the hems can be covered on the guide rods and move up and down along the guide rods, which ensures and strengthens the overall windproof intensity of the window frames on the one hand, and guarantees the smoothness of the movement of the curtain cloth on the other hand.

6. A piece of cloth can be folded in two to form hems having a circumferentially closed space. When the hems are wound by the tubular motor together with the curtain cloth, the hems are pressed flat. The hems have the same thickness as the curtain cloth and always remain flat. As such, the curtain cloth is entirely and flatly wound around the aluminium tube, which overcomes the problem of the curtain cloth being displaced when the windproof curtain is wound.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various variations, modifications and amendments can be made to these embodiments by those of ordinary skills in the art without departing from the spirit or scope defined by the appended claims.
