Description

Technical Field

[0001] This invention relates to the fields of building exterior sunshade roller shutter boxes, natural ventilation of building doors and windows, and interior side maintenance technology, specifically to an exterior sunshade roller shutter box structure with an interior side window-type opening interface. Background Technology

[0002] External shading roller blind boxes are typically located above the exterior windows of a building, housing the roller blind, roller shaft, and power and transmission components. The internal components of the box may require inspection, maintenance, cleaning, or replacement during use. For high-rise buildings, operations performed from the exterior often involve working at heights, making maintenance organization and safety assurance inconvenient. For external shading roller blind boxes where the interior side directly forms the interior space interface, a removable inspection panel or sealing plate is often installed on the interior side. This plate is removed for maintenance and then resealed afterward.

[0003] On the other hand, building windows serve the function of daily natural ventilation. During periods of continuous rainfall, strong winds, or typhoons, people typically close ordinary exterior windows, especially those that open directly into the wind, limiting natural ventilation and affecting indoor air quality. Installing separate ventilation components or equipment would increase the number of components, installation interfaces, and maintenance requirements.

[0004] Therefore, the maintenance space and interface on the interior side of the roller shutter box are usually underutilized in daily use. There is still room for further optimization in how to make the interior interface accommodate daily natural ventilation, internal maintenance, inspection, and cleaning functions without affecting the external sunshade, storage, and enclosure functions of the roller shutter box, thereby improving the functional utilization efficiency and maintenance convenience of this area. Summary of the Invention

[0005] The purpose of this invention is to provide an external sunshade roller shutter box structure with an indoor window-type opening interface, so that the indoor side of the roller shutter box forms a window-type opening interface, forming an indoor closed enclosure interface in the closed state, and forming a natural air exchange path in the open state. The space formed by the opening can be used for maintenance, inspection, cleaning, adjustment, retrieval or replacement of the inside of the roller shutter box when needed. When it is necessary to improve the sealing performance of the indoor side, the window sash sealing boundary can be formed by the frame and sash in conjunction with the surrounding sealing elements.

[0006] To achieve the above objectives, the present invention adopts the technical solution described in claim 1. An opening-fitting frame, an interior-side opening sash (15), and opening hardware (18) are provided at the interior-side window opening (16). The interior-side opening sash (15) is openably and closably connected to the opening-fitting frame via the opening hardware (18), and the frame and sash together form an openable and closable interior-side window opening interface. When closed, the interior-side opening sash (15) engages with the opening-fitting frame and covers the interior-side window opening (16), forming a closed enclosure interface on the interior side of the roller shutter box. In a preferred embodiment, a sealing element is provided around the frame and sash, forming a window sash sealing boundary when closed.

[0007] The opening and fitting frame can be integrally formed by the corresponding frame components of the roller shutter box body located around the indoor side window-type opening (16), or it can be formed by connecting and combining the corresponding frame components with independently set opening and fitting frame components (12). The corresponding frame components may include an upper mounting frame (10), a bottom frame (13), and / or two end frames (20). The upper mounting frame (10) forms the upper structural boundary of the roller shutter box body and is used to fit with the building opening; the two end frames (20) form the structural boundaries of the roller shutter box body at both ends along the length direction.

[0008] The outer frame of the roller shutter box, the opening and fitting frame, and the indoor opening sash frame can be constructed with appropriate profiles according to the project's thermal and structural requirements. The frame located at the main indoor and outdoor thermal separation position can adopt a low thermal conductivity, heat insulation, or heat insulation structure, and functional filling materials can be set in the profile with hollow cavity to further improve thermal insulation, sound absorption, or damping performance.

[0009] The indoor side opening fan (15) can be opened by inward opening and top hanging, push-pull or flip-up-sliding combined opening.

[0010] The indoor side opening fan (15) can be set as a whole along the length of the roller shutter box, or it can be set in sections along the length; when set in sections, it includes at least two opening fan sections (151) that can be opened independently or in conjunction.

[0011] A detachable screen assembly (17) may be installed at the indoor side window opening (16) or at a position adjacent to the opening and fitting frame to block insects, fluff, dust or larger particles from entering the room. The detachable screen assembly (17) is detachable, washable or replaceable, and can be removed or moved when maintenance, repair, cleaning or other operations are required inside the roller shutter box.

[0012] The roller blind (101) is a retractable external sunshade curtain that can be stored in the roller blind receiving cavity and unfolded downward through the roller blind outlet (103) to form an external sunshade function.

[0013] The roller shutter box can be set independently relative to the window below, or it can be used as a partial structure of the integrated window to cooperate with the window below.

[0014] The outdoor side enclosure (11) can be directly exposed on the building facade, or it can be located on the indoor side of the building facade cladding structure (2) and be wholly or partially covered by the cladding structure.

[0015] In a preferred arrangement, the maximum motion envelope boundary formed by the indoor-side opening fan (15) when it is opened does not exceed the finished surface (3) of the indoor-side exterior wall, so as to reduce spatial interference with adjacent structures and facilities on the indoor side, such as curtains, curtain boxes, ceilings or nearby furniture.

[0016] Since the opening space is connected to the outside through the roller shutter receiving cavity and the roller shutter outlet (103), the air exchange path is not directly from the indoor opening to the outside. The external airflow changes direction when passing through the roller shutter receiving cavity. Therefore, under strong wind and rain conditions, this non-direct air exchange path helps to reduce the direct effect of high-speed airflow and wind-driven rain on the indoor opening fan (15) and opening hardware (18).

[0017] The beneficial effects of this invention are as follows:

[0018] The interior side of the roller shutter box forms a window-like opening interface consisting of an opening and fitting frame, an interior opening sash, and opening hardware, which can be opened and closed like an opening window. When closed, it forms a closed enclosure interface on the interior side of the roller shutter box, and when open, it forms a natural air exchange path. In embodiments where a sealing element is provided around the frame and sash fitting, the sealing element can also form a window sash sealing boundary when closed, further improving the sealing performance of the interior interface.

[0019] When maintenance, repair, cleaning, adjustment, removal, or replacement of the roller shutter box is required, the space created by opening it can be used to approach the roller shutter housing cavity from the indoor side. This improves the convenience of indoor operation and reduces the need to approach the roller shutter box from a high altitude on the outdoor side.

[0020] The roller shutter box can be set independently relative to the window below, or it can be used as a partial functional structure in an integrated window or other window and door system, making it easy to adapt to different building window combinations.

[0021] The maximum motion envelope boundary of the indoor operable sash can be controlled within the range of the finished surface of the indoor exterior wall, which helps to reduce spatial interference with adjacent structures and facilities on the indoor side.

[0022] The natural air exchange path forms a non-direct path through the roller shutter cavity and roller shutter outlet, which helps to reduce the direct effect of strong external airflow and wind-driven rain on the indoor opening interface under strong wind and rain conditions.

[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0032] like Figures 1 to 3 as well as Figure 7 As shown, a roller blind housing cavity is formed inside the roller blind box. The roller blind 101 is rolled up or stored on the roller blind shaft 102 or other storage components, and can be unfolded downward through the roller blind outlet 103. An interior window-type opening 16 is provided on the interior side of the roller blind box. The interior opening sash 15 is openable and closable by means of opening hardware 18 and opening mating frame.

[0033] When the indoor-side operable sash 15 is closed, it engages with the opening and fitting frame and covers the indoor-side window opening 16, forming a closed enclosure interface on the indoor side of the roller shutter box. In a preferred embodiment, a sealing element is provided around the frame and sash assembly, forming a window sash sealing boundary when the indoor-side operable sash 15 is closed. When the indoor-side operable sash 15 is open, an opening space communicating with the roller shutter receiving cavity is formed between the frame and sash. This opening space communicates with the outside via the roller shutter receiving cavity and the roller shutter outlet 103, thereby forming a natural air exchange path between the indoor and outdoor areas.

[0034] When maintenance, repair, cleaning, adjustment, removal, or replacement of the roller shutter box is required, the space created by opening the indoor side opening fan 15 can be used to approach the roller shutter receiving cavity from the indoor side.

[0035] The opening and fitting frame can be integrally formed by corresponding frame components located around the interior side window-type opening 16 of the roller shutter box, or it can be formed by connecting and combining the corresponding frame components with independently set opening and fitting frame members 12. The corresponding frame components may include an upper mounting frame 10, a bottom frame 13, and / or end frames 20. The upper mounting frame 10 forms the upper structural boundary of the roller shutter box and is used to fit with the building opening; the end frames 20 form the structural boundaries at both ends of the roller shutter box along the length direction.

[0036] like Figure 3 As shown, in one embodiment, the roller shutter box is located above the building's exterior window opening, and the exterior cladding panel 11 is located on the interior side of the building's exterior facade cladding structure 2 and is wholly or partially covered by the cladding structure; in another embodiment, the exterior cladding panel 11 can be directly exposed on the building's exterior facade. An exterior window can be installed below the roller shutter box.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, the indoor side opening fan 15 can adopt an inward opening top-hung, push-pull, or top-flip-sliding composite opening method, and can be opened and closed by corresponding opening hardware and opening matching frame.

[0038] like Figure 6a , Figure 6b As shown, the indoor-side operable fan 15 can be integrally arranged along the length of the roller shutter box, or it can be arranged in segments along the length. When arranged in segments, it includes at least two operable fan segments 151, each operable fan segment 151 can be opened independently or in conjunction with each other.

[0039] A detachable screen assembly 17 may be installed at the 16 indoor side window openings or adjacent to the opening and fitting frame. During daily ventilation, the detachable screen assembly 17 is used to block insects, lint, dust, or larger particles; it can be removed or moved when maintenance, inspection, cleaning, or other operations are required inside the roller shutter box. The detachable screen assembly 17 can be washed or replaced.

[0040] The outer frame of the roller shutter box, the opening and fitting frame, and the indoor opening fan frame can be constructed with appropriate profiles according to the project's thermal and structural requirements; the frame located at the main indoor and outdoor thermal separation position can adopt a low thermal conductivity, heat insulation or heat insulation structure, and functional filling materials can be set in the profile with hollow cavity.

[0041] The roller shutter box can be set independently relative to the lower window 1, or it can be used as a partial structure of the integrated window in conjunction with the lower window 1.

[0042] In a preferred arrangement, the maximum motion envelope boundary formed by the indoor operable fan 15 when it is opened does not exceed the finished surface 3 of the indoor exterior wall, so as to reduce spatial interference with adjacent structures and facilities on the indoor side.

[0043] Because the indoor opening space is connected to the outside through the roller shutter receiving cavity and roller shutter outlet 103, the air exchange path is not a direct connection from the indoor opening to the outside. The external airflow changes direction when passing through the roller shutter receiving cavity. Therefore, under strong wind and rain conditions, this non-direct air exchange path helps to reduce the direct effect of high-speed airflow and wind-driven rain on the indoor opening fan 15 and opening hardware 18.

[0044] The above embodiments are used to illustrate the present invention, and the scope of protection of the present invention is defined by the claims.
