Description

A narrow-frame door and window structure and door and window Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a narrow-frame door and window structure and door and window. Background Technology

[0002] Doors and windows are essential components of buildings and are among the furniture items that every household must consider when decorating. The lighting performance of doors and windows directly affects the quality of the indoor lighting environment. If the lighting performance of doors and windows is poor, lighting needs can only be met by artificial lighting. Insufficient sunlight indoors for extended periods not only negatively impacts walls and furniture but also directly affects people's eyesight, health, safety, work efficiency, and mental well-being. Therefore, the lighting performance of doors and windows is one of the important indicators to consider in door and window design. For lighting performance testing, the light-receiving area is a crucial parameter. In buildings, the wall area occupied by doors and windows includes the outer frame, so the outer frame is also part of the light-receiving area. Therefore, the outer frame of doors and windows must be considered when testing their lighting performance.

[0003] However, with the continuous increase in market demand, ordinary doors and windows on the market, due to their large visible surfaces of the window frames and sashes and insufficient light transmission, cannot meet market demands. Therefore, there is an urgent need to design a new type of door and window structure to solve the lighting problem of traditional doors and windows. Summary of the Invention

[0004] This utility model provides a narrow-frame door and window structure and door and window to improve the lighting effect of the door and window structure.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0044] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] This utility model embodiment provides a narrow-frame door and window structure. By adjusting the installation method of the locking hardware and opening hardware, the visible surface of the sash profile is reduced, thereby increasing the overall lighting area of ​​the door and window structure.

[0046] First embodiment:

[0047] As shown in Figures 1-5, a narrow-frame door and window structure according to the first embodiment of this utility model includes a frame profile 1, a sash profile 2, glass 3, locking hardware 4, and opening hardware 5. The frame profile 1 is installed at the window; the sash profile 2 is movably mounted on the frame profile 1, and the glass 3 is installed on the sash profile 2. The locking hardware 4 is installed on the surface of the glass 3 and connected to the frame profile 1, thereby providing a locking function. A portion of the opening hardware 5 is closably connected between the frame profile 1 and the sash profile 2, allowing the frame profile 1 and the sash profile 2 to open and close; and another portion of the opening hardware 5 is installed on the surface of the glass 3 and connected to the frame profile 1, serving to support the sash profile 2.

[0048] Specifically, as shown in Figure 1, the frame profile 1 includes an outer frame 11, an inner frame 12, and a connecting portion 13. The outer frame 11 is used for an openable connection with the sash profile 2, the inner frame 12 is used for connection with the locking hardware 4 and the opening hardware 5, and the connecting portion 13 connects the outer frame 11 and the inner frame 12. Furthermore, as shown in Figure 2, in another embodiment, the outer frame 11 has an edge-sealing portion 111 for engaging with the sealing edge of the window, thereby improving the sealing performance of the frame profile 1 during installation.

[0049] As shown in Figure 1, in this embodiment, the fan-shaped profile 2 is L-shaped, consisting of a bottom edge 21 and a side edge 22. The two ends (top and bottom) of the glass 3 are respectively glued to the bottom edge 21 of the L-shaped fan profile using glass adhesive, so that the side surface of the glass 3 (i.e., the surface on the left in Figure 1) abuts against the side edge 22 of the L-shaped fan profile. It can be understood that in this embodiment, by installing a portion of the locking hardware 4 and the opening hardware 5 onto the glass 3 (described in detail below), the installation of the locking hardware 4 and the opening hardware 5 onto the side edge 22 of the L-shaped fan profile is avoided, thereby effectively reducing the width h of the side edge 22 of the L-shaped fan profile. Correspondingly, the smaller the width h of the side edge 22 of the L-shaped fan profile, the less visible surface the fan profile 2 has, thus reducing light obstruction and increasing the light-receiving area.

[0050] As shown in Figure 1, in this embodiment, preferably, a sealing strip mounting groove 121 is provided on the side of the inner frame 12 near the glass. A sealing strip 122 is installed in the sealing strip mounting groove 121 to seal the gap between the frame profile 1 and the glass 3, thereby improving the sealing performance of the door and window structure. Furthermore, more preferably, the glass 3 is any one of insulated glass, vacuum glass, or laminated glass, which helps to improve light transmission and aesthetics.

[0051] As shown in Figures 3 and 4, in this embodiment, the locking hardware 4 includes a first locking member 41 and a second locking member 42. The first locking member 41 is installed at the bottom of the right side surface of the glass 3, and the second locking member 42 is installed on the inner bottom wall of the frame profile 1 at a corresponding position to the first locking member 41, and is detachably connected to the first locking member 41, so that the first locking member 41 and the second locking member 42 can switch between a locked state (as shown in Figure 3) and an unlocked state (as shown in Figure 4). It can be understood that when the locking hardware 4 is in the locked state shown in Figure 3, the fan profile 2 and the frame profile 1 are relatively fixed; when the locking hardware 4 is in the unlocked state shown in Figure 4, the fan profile 2 and the frame profile 1 can be opened and closed.

[0052] As shown in Figures 1 and 5, in this embodiment, the opening hardware 5 includes a rotating part 51 and at least one supporting part 52. This embodiment uses two supporting parts 52 as an example, but the specific number of supporting parts 52 is not limited. The rotating part 51 is a hinge, rotatably connected between the top of the fan-shaped profile 2 and the inner top wall of the frame profile 1, allowing the frame profile 1 and the fan-shaped profile 2 to open and close. Furthermore, the two supporting parts 52 are respectively installed on both sides of the glass 2 surface and connected to the frame profile 1 to provide support force, keeping the fan-shaped profile 2 in the open state.

[0053] Specifically, the support portion 52 includes a support base 521 and an expansion head 522. The support base 521 is fixed to one side of the glass 2 surface and has a limiting groove 5211. One end of the expansion head 522 is connected to the inner frame 12 of the frame profile via a connector (e.g., a connecting screw), and the other end matches the limiting groove 5211, thereby enabling switching between an expanded state and a contracted state. For example, the expansion head 522 can be a hollow metal ball, which expands or contracts due to its own elasticity. The specific structural form of the expansion head 522 can be adaptively adjusted as needed, as long as it can cooperate with the limiting groove 5211 to achieve expansion and contraction.

[0054] Therefore, as the frame profile 1 and the fan profile 2 gradually open, the expansion head 522 gradually disengages from the limiting groove 5211 and continuously expands until it is completely disengaged from the limiting groove 5211, thus supporting the outer wall of the limiting groove 5211 and keeping the fan profile 2 in the open state. As the frame profile 1 and the fan profile 2 gradually close, the expansion head 522 is gradually compressed into the limiting groove 5211 until the frame profile 1 and the fan profile 2 are completely closed, at which point the expansion head 522 is completely pressed into the limiting groove 5211.

[0055] It is understood that in this embodiment, by installing the support part 52 in the locking hardware 4 and the opening hardware 5 on the surface of the glass 3, the visible surface of the sash profile 2 can be effectively reduced, thereby increasing the overall lighting area of ​​the door and window structure.

[0056] Second embodiment:

[0057] Figure 6 shows a narrow-frame door and window structure provided in the second embodiment of this utility model, including a frame profile 1, a sash profile 2, glass 3, locking hardware 4, and opening hardware 5. The difference between this embodiment and the first embodiment lies in the different structural form of the opening hardware 5.

[0058] Specifically, in this embodiment, the opening hardware 5 is at least one support hinge. One end of the support hinge 5 is installed on one side of the glass surface, and the other end is connected to the frame profile 1 for opening and closing and supporting the fan profile 2. Preferably, there are two support hinges 5, which are respectively installed on both sides of the glass surface 3 and rotatably connected to the frame profile 1. Thus, the opening and closing of the fan profile 2 is achieved by the synchronous rotation of the two support hinges 5, and the structural strength of the support hinges 5 themselves is used to support the fan profile 2, so that the fan profile 2 remains in the open state.

[0059] It should be understood that the structure of the support hinge 5 itself is a conventional structure in the art and will not be described in detail here. In this embodiment, by installing the support hinge 5 on the surface of the glass and rotatably connecting it with the frame profile 1, the fan profile 2 can be opened and closed and supported simultaneously. This eliminates the need to install the opening hardware 5 as a two-part structure, improving the convenience of installation and construction efficiency.

[0060] Except for the differences mentioned above, the structure of this embodiment is the same as that of the first embodiment, and will not be described again here.

[0061] Third embodiment:

[0062] Based on the first and second embodiments described above, the third embodiment of this utility model also provides a door and window, which includes any of the narrow-frame door and window structures described above.
