Description
Technical Field
[0001] This utility model belongs to the field of building technology, specifically referring to a door and window system with bottom-mounted glass. Background Technology
[0002] Currently, most residential balconies on the market feature glass railings, with some high-end developments extending the railings down to below the balcony beams for a larger and more aesthetically pleasing decorative surface. However, for safety, wind and water protection, and to increase usable space, homebuyers often enclose their balconies with windows, requiring the removal of the railings and glass. To maintain a unified and harmonious building facade, property management often requires the lower part of the balcony, where railings and glass have been removed, to be restored to glass, and that the restored glass be on the same vertical plane as the upper balcony window. Because the upper part of the lower glass loses its fixed support point after railing removal, and maintaining the same vertical plane requires moving the entire balcony window outwards, the bottom of the window is partially suspended, with only part of the bottom frame resting on the upper surface of the balcony beams. This uneven stress on the window could lead to swaying or even collapse.
[0003] Therefore, given the current situation in the market, it is urgent to design a door and window system that can integrate the bottom-mounted glass and balcony window, provide stable support for the balcony window, and ensure that the outer surfaces of the two parts are in the same vertical plane. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model proposes a door and window system with bottom-mounted glass.
[0005] This utility model is achieved through the following technical solution: a door and window system with a bottom-hanging glass, mainly composed of a balcony door and window with a bottom frame, an upper fixed base is provided at the lower end of the bottom frame of the door and window, a bottom-hanging glass is provided at the lower end of the upper fixed base, and a fixed support is also provided at the bottom of the bottom frame of the door and window, and the outer side of the balcony door and window and the outer side of the bottom-hanging glass are located in the same vertical plane.
[0006] As one of the preferred embodiments, the upper fixed base consists of a connector with a plug hole, a vertical stop at the bottom of the connector, and a retaining edge with a plug; the connector is fixedly connected to the lower frame of the door or window, the plug of the retaining edge is inserted into the plug hole and fixedly connected to the connector, and an upper retaining groove is formed between the retaining edge and the vertical stop.
[0007] As a second preferred embodiment, the upper fixed base consists of a connector with a plug hole, a vertical stop at the bottom of the connector, a snap-fit edge with a plug, and a buckle at the top of the connector; the bottom of the lower frame of the door and window is provided with a socket, the connector is inserted into the socket and fixedly connected to the lower frame of the door and window by the buckle, the plug of the snap-fit edge is inserted into the socket and fixedly connected to the connector, and an upper slot is formed between the snap-fit edge and the vertical stop.
[0008] To further ensure the stability of the lower glass, a lower fixing base is also provided at the lower end of the lower glass.
[0009] To ensure the stability of the entire balcony door and window, the fixing support is inverted L-shaped.
[0010] Furthermore, the interior of the insertion hole is provided with a number of annular inner protrusions, and the surface of the insertion connector on the snap edge is provided with a number of annular outer protrusions that match the annular inner protrusions.

Detailed Implementation
[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0021] Example
[0022] This embodiment
[0023] like Figure 1 , 2 As shown, in this embodiment, the upper frame 1, the lower frame 3, and the window glass 2 disposed between the upper frame 1 and the lower frame 3 together constitute the balcony door and window, which is the traditional enclosed window part of the balcony.
[0024] Below the bottom frame 3 of the door and window is the balcony lower beam 4, meaning the bottom frame 3 of the door and window is fixedly installed on the balcony lower beam 4. The bottom of the balcony lower beam 4 can have an outward-extending section, which is the balcony lower beam protrusion 5, thus making the entire balcony lower beam 4 L-shaped in cross-section. Of course, depending on the actual design requirements, the balcony lower beam 4 may not have the balcony lower beam protrusion 5.
[0025] When the bottom of the balcony beam 4 is provided with a balcony beam protrusion 5, the upper fixed base 6 is fixed on the lower frame 3 of the door and window, and the lower fixed base 10 can be installed on the balcony beam protrusion 5. At this time, the upper fixed base 6 is located above the lower fixed base 10, and the lower-hanging glass 8 is fixedly installed between the upper fixed base 6 and the lower fixed base 10.
[0026] When the bottom of the balcony lower beam 4 does not have a balcony lower beam protrusion 5, the upper fixed base 6 is still fixedly connected to the lower frame 3 of the door and window. The upper end of the lower-hanging glass 8 is directly fixed to the bottom of the upper fixed base 6, while the lower end of the lower-hanging glass 8 can be directly placed on the balcony floor. Alternatively, a supporting structure that can support the lower fixed base 10 can be set on the balcony floor, and the lower end of the lower-hanging glass 8 is fixed to the lower fixed base 10, which in turn is fixed to the supporting structure.
[0027] The upper fixed base 6 consists of a connecting seat 63 with a plug hole 67, a vertical retaining edge 65 disposed at the bottom of the connecting seat 63, and a retaining edge 64 with a plug connector 68. The plug hole 67 is disposed on the side wall of the vertical retaining edge 65. When the upper fixed base 6 is connected to the lower frame 3 of a door or window, it can be connected in the following two ways: one is as follows Figure 2 As shown, a horizontal end is formed at the top of the connector 63, and a buckle 69 is provided on this horizontal end. A socket 70 matching the buckle 69 is provided at the bottom of the lower frame 3 of the door / window. When the connector 63 is inserted into the socket 70 via the buckle 69, the connector 63 is fixedly connected to the lower frame 3 of the door / window. To ensure a secure connection, the horizontal end of the connector 63 can also be fixedly connected to the lower frame 3 of the door / window using screws.
[0028] The second way to connect the upper fixed base 6 to the lower frame 3 of the door and window is as follows: Figure 3 As shown, a vertical fixed end is provided on the upper part of the connecting seat 63, and a vertical connecting base 61 is provided at the bottom of the lower frame 3 of the door and window. The vertical fixed end is located on the outside or inside of the connecting base 61 and is fixedly connected to it by screws 62, so that the entire upper fixed base 6 is fixed together with the lower frame 3 of the door and window to form a whole.
[0029] The connector 63 has a plurality of annular inner protrusions 671 inside its insertion hole 67, while the connector 68 of the retaining edge 64 has a plurality of annular outer protrusions 681 on its surface. The annular inner protrusions 671 and the annular outer protrusions 681 are structurally matched. When the connector 68 of the retaining edge 64 is inserted into the insertion hole 67 of the connector 63, the annular outer protrusions 681 engage with the annular inner protrusions 671, thus tightly fixing the retaining edge 64 to the connector 63 without detaching. Its structure is as follows: Figure 3 As shown.
[0030] Alternatively, the connector 68 can be composed of an upper insert 682 and a lower insert 683 arranged opposite to each other, and both the upper insert 682 and the lower insert 683 have an annular outer protrusion 681 that matches the annular inner protrusion 671, as shown in the following structure. Figure 2As shown. When the connector 68 of the retaining edge 64 is inserted into the connector hole 67 of the connector 63, the annular outer protrusion 681 will engage with the annular inner protrusion 671, thereby making the retaining edge 64 and the connector 63 tightly and fixedly connected together without detaching.
[0031] When the connector 68 of the retaining edge 64 is inserted into the connector hole 67 of the connecting seat 63, an upper retaining groove 66 is formed between the lower end of the retaining edge 64 and the vertical stop edge 65. Correspondingly, a lower retaining groove is also provided on the lower fixing base 10 provided on the balcony lower beam protrusion 5, and the opening of the upper retaining groove 66 corresponds to the opening of the lower retaining groove. The lower hanging glass 8 is set and fixed between the upper retaining groove 66 and the lower retaining groove. Conversely, if the balcony lower beam 4 does not have a balcony lower beam protrusion 5, then the lower retaining groove is not required.
[0032] To ensure the stability of the entire balcony door and window, this embodiment requires a fixed support 7 to support the entire balcony door and window. The fixed support 7 is manufactured in an inverted L shape, meaning it has a short side and a long side, which are perpendicular to each other. The short side is embedded in the gap between the connecting seat 63 and the bottom surface of the lower frame 3 of the door and window, while its long side is close to the side of the lower beam 4 of the balcony and is fixed to the side of the lower beam 4 of the balcony using expansion bolts 9, thereby fixing the entire fixed support 7 to the lower beam 4 of the balcony.
[0033] With the above structure, this embodiment allows the balcony door and window, formed by the upper frame 1, the glass 2, and the lower frame 3, to be moved outwards towards the balcony, so that a portion of the entire balcony door and window is located outside the lower beam 4, meaning a portion of the balcony door and window is suspended outside the lower beam 4. Because this embodiment includes a fixed support 7, it ensures that the portion of the balcony door and window suspended outside the lower beam 4 has sufficient support points, thus ensuring the stability of the entire balcony door and window. Simultaneously, the presence of the upper fixed base 6 ensures that the lower glass 8 is tightly fixed to the lower end of the portion of the balcony door and window located outside the lower beam 4, ultimately placing the glass 2 and the lower glass 8 in the same vertical plane.
[0034] As described above, this utility model can be implemented quite well.
