Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present application, embodiments of the present application will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

As shown in fig. 1, the application provides an inner suspension film door window, which comprises two layers of hollow glass 1 arranged in parallel, wherein at least one inner suspension film 2 is arranged in a cavity between the two layers of glass 1, the inner suspension film 2 is arranged in a tensioning frame 3 in a tensioning state, and the tensioning frame 3 and the inner suspension film 2 tensioned on the tensioning frame are arranged between the two layers of glass 1 as an independent component, so that the tensioning problem of the inner suspension film does not need to be considered when the glass door window is installed, and the installation complexity is reduced.

Further, in the illustrated embodiment, both sides of the tension frame 3 may be bonded between the two sheets of glass 1 by spacer bars 4. For example, the spacer 4 may be an existing composite butyl aluminum spacer, butyl rubber for adhesion is provided on both sides of the spacer 4, and a molecular sieve for adsorbing water vapor may be provided in a hollow structure inside the spacer 4. The inner suspension film door and window shown in the figure is only provided with one layer of inner suspension film 2, and can also be deformed into a structure with two or more layers of inner suspension films in a mode of additionally arranging the tensioning frame 3 according to needs.

The inner suspension film 2 is made of a plastic film with good heat-resistant and insulating effects, and needs to be tensioned between hollow glasses to keep light rays transmitted in parallel and avoid visual deformation.

The tensioning operation of the inner suspension film in the prior art is very complicated, four edges of the inner suspension film need to be clamped on a plurality of elastic elements respectively during installation, and the tensioning force needs to be locally and repeatedly adjusted in order to prevent wrinkling. In addition, the interior membrane of hanging repeats expend with heat and contract with cold in the long-term use, and the tensile force difference can lead to the film to local position extrusion formation fold, and this can influence glass door and window's permeability, and the outdoor scenery of observation can produce visual deformation because of the refraction.

In order to solve the above problem, as seen in the exploded perspective view of the tension frame 3 shown in fig. 2, the four sides of the inner suspension film 2 of the present application are wound around four reels 21, respectively, and both ends of the four reels 21 are mounted inside the tension frame 3 by elastic tensioners 5, respectively.

In one illustrated embodiment, in order to facilitate the exposure of both ends of the winding shaft 21 while tensioning the inner suspension film 2, the inner suspension film 2 is rectangular with four corners cut off so that the width of the four sides of the inner suspension film 2 becomes narrower as they approach the edge positions, and thus the winding thickness of the inner suspension film 2 on the winding shaft 21 becomes thicker as it approaches the middle of the winding shaft 21 and becomes thinner as it approaches both ends of the winding shaft 21 when wound on the winding shaft 21. That is, the inner suspension film 2 wound around the winding shaft 21 is formed into a spindle shape having a thick middle portion and thin ends. Therefore, as the inner suspension film 2 is tightly wound around the winding shaft 21, the tension of the middle position of the inner suspension film 2 is gradually greater than that of the corner position, and the stretching and loosening of the film caused by the thermal expansion of the middle suspended inner suspension film can be offset. Meanwhile, the winding edge of the inner suspension film 2 tends to extend towards the two thinner ends, so that the phenomenon of wrinkles caused by local extrusion of the film is naturally eliminated.

In order to facilitate the winding of the inner suspension film 2 by the winding shaft 21 to generate a uniform tension, it is preferable that the section of the middle portion of the winding shaft 21 for winding the inner suspension film 2 is circular. In addition, in order to facilitate the connection to the elastic tension device 5 without loosing the tension after tensioning, the cross section of the reel 21 for connecting both ends of the elastic tension device 5 is square, so that the reel 21 is not easily rotated.

Alternatively, the second frame 32 may be formed by joining four sectional materials, as in the case of the first frame 31. Alternatively, the first housing 31 may be integrally formed of metal or plastic, as with the second housing 32. Preferably, the frame body for mounting the elastic tensioning device 5 is formed by splicing metal profiles, so that the frame body can have higher supporting strength to adapt to tensioning operation; correspondingly, the other frame body can be made of metal or plastic integrally formed parts.

The second frame 32 may be snap-fitted inside the first frame 31 as shown in fig. 1, or in a not shown embodiment, the first frame 31 may be snap-fitted inside the second frame 32.

In another embodiment, not shown, the heights of the first annular inner flange 311 and the second annular inner flange 321 may be varied, for example, the height of the first annular inner flange 311 for installing the first frame 31 of the elastic tensioning device 5 may be slightly higher, so that the inner suspension membrane 2 is raised by the first annular inner flange 311 to form a bending angle after being installed, thereby increasing the tensioning degree of the inner suspension membrane 2 and improving the sealing effect of the first annular inner flange 311 against the inner suspension membrane 2. Of course, in a further embodiment, not shown, it may also be provided that the second annular inner flange 321 is slightly higher in height, so that the inner suspension membrane 2 is lifted by the second annular inner flange 321 after installation.
