Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, specifically to a door and window with a horizontal mullion and a telescopic clothes rack. Background Technology

[0002] Currently, floor-to-ceiling windows and balcony doors are widely used in residential and public buildings to achieve good lighting and views. These types of windows and doors usually require horizontal or central struts (collectively referred to as "horizontal and central struts") to increase their overall structural strength, improve wind pressure resistance, and prevent profile deformation.

[0003] However, the existing door and window mullions function too simply, serving only as structural reinforcements without fully considering their role in maximizing interior space. This is especially true in apartment buildings or small residences where balconies are the primary areas for drying clothes. Users typically need to install external clothes racks, place floor-standing clothes racks, or use retractable clotheslines. These methods all have drawbacks: external clothes racks are complex to install, may affect the building's appearance, and pose safety hazards; floor-standing and retractable clothes racks occupy valuable balcony space, affecting the convenience of movement and passage, and making the space appear cluttered and cramped. Furthermore, in windy weather, clothes installed on external drying devices are easily blown off or tangled, resulting in poor drying stability.

[0004] Therefore, there is an urgent need for an innovative solution that can integrate drying functions while ensuring the original structural strength and wind pressure resistance of doors and windows, and maximize the saving and optimization of space utilization, thereby solving many problems existing in the above-mentioned technologies. Utility Model Content

[0005] In order to provide the original structural strength of doors and windows while optimizing space utilization, this utility model provides a door and window with a horizontal mullion and a telescopic clothes rack.

[0006] The technical solution adopted by this utility model is as follows: A door and window with a telescopic clothes drying rack on a horizontal center mullion includes: a fixed support frame, which is fixedly installed on the horizontal center mullion of the door and window; a movable clothes drying rack, which has a first position where it is retracted to be hidden under the fixed support frame and a second position where it extends to be used outside the fixed support frame, wherein when the movable clothes drying rack is in the second position, the top surfaces of the fixed support frame and the movable clothes drying rack are joined together to form a continuous drying surface; and a lifting and translating component, which is disposed between the fixed support frame and the movable clothes drying rack, for switching the movable clothes drying rack between the first position and the second position.

[0007] Preferably, the lifting and translating assembly includes: an outer slide rail, horizontally mounted on the fixed support frame; an inner slide rail, slidably engaged with the outer slide rail, retracting or extending along the length of the outer slide rail; an extension frame, movably connected to the inner slide rail, the movable drying rack being fixedly mounted on the extension frame; at least two connecting rods, connecting the extension frame and the inner slide rail to form a parallelogram linkage mechanism; and an elastic reset member, disposed between the extension frame and the inner slide rail, for providing an elastic force to the extension frame to tend to rise.

[0008] Preferably, the elastic reset element is a tension spring, one end of which is connected to the inner slide rail and the other end is connected to the extension frame.

[0009] Preferably, the lifting and translating assembly further includes a damper, which is disposed between the extension frame and the inner slide rail to provide damping and buffering for the lifting and lowering movement of the extension frame.

[0010] Preferably, the damper is a linear damping rod, with its two ends connected to the inner slide rail and the extension frame, respectively.

[0011] Preferably, the damper is a rotary damper, which is mounted on the hinge shaft in the parallelogram linkage mechanism.

[0012] Preferably, both the fixed support frame and the movable drying rack are equipped with hooks or hanging rods for hanging clothes hangers.

[0013] Preferably, at least one set of the lifting and translating components is arranged on each side of the fixed support frame and the movable drying rack.

[0014] This utility model has the following beneficial effects: 1. Space utilization: The clothes drying function is integrated into the horizontal beam of the door and window, and a retractable and hidden design is adopted. When not in use, the movable clothes drying rack can be retracted and hidden under the fixed support frame, which does not affect people's activities and passage on the balcony or indoors. It is suitable for small apartments and users who pursue minimalist living space, and solves the problem of traditional floor-standing or external clothes drying racks occupying indoor and outdoor space. 2. Structural Reinforcement: The bracket supporting the drying function is combined with the inherent structural component of the door and window, the horizontal mullion, so that the horizontal mullion is transformed from a single structural reinforcement component into a composite component that combines structural support and drying function. This not only adds practical function, but also enhances the structural strength and wind pressure resistance of the door and window, and improves the safety of the product. 3. Easy to operate: Through the lifting and translation assembly consisting of a parallelogram linkage mechanism, an elastic reset component and a damper, users can smoothly and effortlessly extend and retract the movable drying rack. The elastic reset component assists in lifting the drying rack and reduces the operating force; the damper ensures that the movement is smooth, controllable and quiet, avoiding the impact, noise or hand pinching risk that may be caused by sudden lifting. 4. Anti-fall: When the movable drying rack extends to the use position, its top surface and the top surface of the fixed support frame are joined together to form a continuous and flat drying surface. It has a strong overall integrity and can effectively prevent clothes from being easily blown off or tangled in windy weather compared to clothes racks that are completely suspended outside. This improves the reliability and safety of drying. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0020] In the embodiments, such as Figures 1-3The diagram shows a door / window with a telescopic clothes drying rack attached to a horizontal center mullion 5. It includes: a fixed support frame 1, fixedly installed on the horizontal center mullion 5 of the door / window 4; a movable clothes drying rack 2, having a first position retracted below the fixed support frame 1 and a second position extended outside the fixed support frame 1 for use. When the movable clothes drying rack 2 is in the second position, the top surfaces of the fixed support frame 1 and the movable clothes drying rack 2 are joined together to form a continuous drying surface; and a lifting and sliding assembly 3, disposed between the fixed support frame 1 and the movable clothes drying rack 2, used to switch the movable clothes drying rack 2 between the first and second positions. The connection between the fixed support frame 1 and the horizontal center mullion 5 can be by bolt connection, snap-fit ​​connection, or integral extrusion molding with the profile. The cross-sectional shape of the movable clothes drying rack 2 matches the fixed support frame 1 to ensure flatness after splicing. This embodiment combines the clothes drying function with the structure of the horizontal center mullion 5 of the door / window. Through the cooperation of the fixed support frame 1, the movable clothes drying rack 2, and the lifting and sliding assembly 3, the concealed storage and flexible use of the clothes drying function are achieved. In the second position, the fixed support frame 1 and the movable drying rack 2 are spliced ​​together to form a continuous drying surface, providing a stable and ample drying space; in the first position, the movable drying rack 2 is completely hidden, saving space and solving the problem of traditional clothes racks occupying space; at the same time, the fixed support frame 1 also enhances the structural strength and rigidity of the horizontal mullion 5, thereby enhancing the overall strength and wind pressure resistance of the door and window 4 and improving the safety of the product.

[0021] In the embodiments, such as Figures 1-2 As shown, the lifting and translating assembly 3 includes: an outer slide rail 3.1, horizontally mounted on the fixed support frame 1; an inner slide rail 3.2, slidably engaged with the outer slide rail 3.1, retracting or extending along the length of the outer slide rail 3.1; an extension frame 3.3, movably connected to the inner slide rail 3.2, with the movable drying rack 2 fixedly mounted on the extension frame 3.3; at least two connecting rods 3.4, connecting the extension frame 3.3 and the inner slide rail 3.2 to form a parallelogram linkage mechanism; and an elastic reset member 3.5, disposed between the extension frame 3.3 and the inner slide rail 3.2, used to provide an elastic force to the extension frame 3.3 to tend to lift. The outer slide rail 3.1 and the inner slide rail 3.2 are responsible for the horizontal translational movement, realizing the extension and retraction of the drying rack. A ball bearing slide rail can be used between them to improve the smoothness and durability of the sliding. The parallelogram linkage mechanism 3.4 is responsible for the vertical lifting and lowering movement. Its movement trajectory is stable, reliably lowering the drying rack to a convenient height for hanging clothes after extension and raising it before retraction to avoid interference. Two or more parallel linkages 3.4 can increase the stability and strength of the movable drying rack 2 when bearing heavy objects. The elastic reset element 3.5 provides automatic lifting force, greatly reducing the force required for user operation and improving ease of use.

[0022] In the embodiments, such as Figures 1-2As shown, the elastic restoring element 3.5 is a tension spring. One end of the tension spring is connected to the inner slide rail 3.2, and the other end is connected to the extension frame 3.3. The tension spring is a simple, low-cost, and highly reliable elastic element. Its installation method effectively utilizes the relative displacement changes between the inner slide rail 3.2 and the extension frame 3.3 during movement to provide just the right elastic restoring force, assisting the drying rack to rise smoothly. Figures 1-2 The position of the midpoint line is the centerline position of the elastic reset element 3.5. The elastic reset element 3.5 can also be a torsion spring mounted on the hinge shaft of the parallelogram linkage mechanism or a compression spring arranged in other ways between the extension frame 3.3 and the inner slide rail 3.2, all of which can achieve the purpose of providing lifting elastic force.

[0023] In the embodiments, such as Figures 1-2 As shown, the lifting and translating assembly 3 also includes a damper 3.6, which is disposed between the extension frame 3.3 and the inner slide rail 3.2 to provide damping and buffering for the lifting and lowering movement of the extension frame 3.3. The damper 3.6 can be a hydraulic damper, a pneumatic damper, or a friction damper. The damper 3.6 can effectively buffer the speed of the movable drying rack 2 during the lifting and lowering process, making its movement smooth, slow, and quiet, completely eliminating the rapid impact, vibration, or noise that may be caused by the action of the elastic reset element 3.5, while avoiding the risk of pinching hands. Figures 1-2 The damper 3.6 is a linear damping rod, with the dotted line indicating its centerline. Its two ends are connected to the inner slide rail 3.2 and the extension frame 3.3, respectively. This structure is easy to install, and the damping direction is consistent with the lifting and lowering direction of the extension frame 3.3, resulting in a linear and significant buffering effect. Alternatively, a rotary damper can be selected for damper 3.6. This rotary damper is mounted on the hinge shaft of the parallelogram linkage mechanism. By suppressing the rotational speed of the hinge shaft, it indirectly achieves the buffering effect of lifting and lowering motion. Its advantages include smaller installation space and easier arrangement and concealment within a compact mechanism.

[0024] In this embodiment, both the fixed support frame 1 and the movable drying rack 2 are equipped with hooks or hanging rods for hanging clothes hangers, meeting the diverse drying needs of users. The hooks can be fixed, flip-up, or sliding for easy storage when not in use. The hanging rods can be round rods integrally formed with the frame body, or they can be separately installed detachable crossbars.

[0025] In this embodiment, at least one set of lifting and translating components 3 is arranged on each side of the fixed support frame 1 and the movable drying rack 2. For drying racks with a longer length, an additional set of lifting and translating components 3 can be added in the middle to form a three-point support, increasing strength and preventing the middle part from sinking and deforming due to heavy objects. This structure ensures that the movable drying rack 2 is evenly stressed and runs smoothly during extension, retraction, and lifting, without jamming or tilting, guaranteeing the reliability, durability, and structural stability of the entire mechanism when drying a large number of clothes.

[0026] Obviously, the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Other obvious variations or modifications derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
