Description

Technology Field

[0001] The present invention relates to a metal window, and more specifically, to a metal window in which window glass is combined with a frame body made of metal material, and multiple sealing parts and gap maintaining parts are provided between the structure and the frame body, thereby improving airtightness and waterproofness and facilitating construction and maintenance. Background Technology

[0002] Various types of windows and doors are installed on the exterior walls or openings of buildings to block external weather, noise, and dust, while maintaining the thermal insulation and airtightness of the interior space. Recently, there have been active attempts to ensure structural strength and durability, as well as aesthetic design, by applying metal materials to these windows and doors.

[0003] These metal windows are generally constructed by forming a frame using corrosion-resistant metal materials such as aluminum or stainless steel, with glass or composite panels inserted. Metal windows significantly contribute to the exterior design of buildings while being advantageous for ensuring performance in thermal insulation, waterproofing, and soundproofing; they are widely used, particularly in high-rise buildings and large commercial facilities.

[0004] However, in conventional metal window and door construction, numerous auxiliary materials and fasteners must be used for the precise installation of the window frame, and separate measurement and correction work is required to maintain the verticality, horizontality, and flatness of the frame during the installation process. In addition, since sealing work such as silicone must be performed manually to ensure the airtightness and waterproofness of the window, there is a problem where the quality of construction varies depending on the skill level of the worker.

[0005] Furthermore, the process of attaching anchors and filling materials to correct the height difference between the fixed frame and the building structure has the disadvantage of being complex and difficult to maintain consistent quality, and there is also a possibility of defects such as poor airtightness, leakage, and condensation occurring during long-term use.

[0006] Accordingly, there is a continuous demand for new types of metal window installation technologies or metal window systems that offer excellent constructability, reliably ensure airtightness, waterproofing, and thermal insulation, and are structurally simple while minimizing construction errors.

[0007] The aforementioned technical configuration is provided as background technology to aid in understanding the present invention and does not constitute prior art widely known in the technical field to which the present invention belongs. Prior art literature

[0008] Korean Registered Patent Publication No. 10-2798050 (Choi Bok-kyung) April 15, 2025. The problem to be solved

[0009] Conventional metal windows and doors had problems such as reduced airtightness due to step differences or gaps between the structural element and the frame body, or decreased waterproofing performance due to reduced resilience caused by long-term compression of the sealing member. Additionally, the simple sealing structure had the disadvantage of easily losing airtightness due to external impacts or minor deformations of the structure.

[0011] According to one aspect of the present invention, a metal window may be provided comprising: a frame body disposed in a structure; and window glass coupled to the frame body.

[0012] The apparatus comprises: an elastic sealing portion disposed between the frame body and the structure; and a gap maintaining portion, one end of which is supported by the elastic sealing portion and the other end of which is supported by the frame body to maintain a gap between the elastic sealing portion and the frame body, wherein the elastic sealing portion comprises: a first sealing portion, one end of which is supported by the structure and the other end of which is supported by the frame body; a second sealing portion, which is provided in a curved manner on one side of the first sealing portion; a third sealing portion, which is provided on one side of the second sealing portion and is supported by the structure; and a fastening member for screw-fastening the first sealing portion and the frame body, wherein one end of the gap maintaining portion is supported by the third sealing portion, and the gap maintaining portion comprises: a gap maintaining body disposed between the third sealing portion and the frame body; and a first elastic support portion, which is rotatably coupled to a pivotal support shaft provided in the gap maintaining body to elastically support the third sealing portion and the frame body, wherein the first elastic support portion comprises a support shaft rotatably coupled to the pivotal support shaft. A first cylinder coupled to one side of the support member shaft; a first support ball coupled to and movable by the first cylinder; a first spring coupled to one side of the first support ball; a first contact arm coupled to the other side of the first spring and supported by one side in contact with the third sealing part; a second cylinder coupled to the other side of the support member shaft; a second support ball coupled to and movable by the second cylinder; a second spring coupled to one side of the second support ball; and a second contact arm coupled to the other side of the second spring and supported by one side in contact with the frame body, wherein one side is coupled to the first contact arm and the other side is coupled to the second contact arm to elastically support the first contact arm and the second contact arm; and further comprising a magnet member provided on the first contact arm and the second contact arm, wherein the second elastic support member comprises a support member disposed between the first contact arm and the second contact arm;and may include a plurality of support springs that elastically support the support member and the first contact arm, and elastically support the support member and the second contact arm. Effects of the invention

[0013] Embodiments of the present invention can effectively block the inflow of external air or moisture by having a plurality of sealing parts (first, second, and third sealing parts) form multiple contact surfaces between the structure and the frame body, thereby ensuring excellent airtightness and waterproofness.

[0014] By configuring the gap maintaining member and the rotatable first elastic support member, it is possible to flexibly respond to minute distortions of the window frame or construction errors of the structure, thereby improving constructability and maintaining airtightness after installation.

These examples are described in sufficient detail to enable those skilled in the art to implement the present invention. It should be understood that various embodiments of the present invention are different but need not be mutually exclusive. For example, specific shapes, structures, and characteristics described herein with respect to one embodiment may be implemented in other embodiments without departing from the spirit and scope of the present invention. Furthermore, it should be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the present invention. Accordingly, the following detailed description is not intended to be limiting, and the scope of the present invention is limited only by the appended claims, including all equivalents to those claimed by the claims, provided they are properly described. Similar reference numerals in the drawings refer to the same or similar functions across various aspects.

[0020] In order to fully understand the present invention, the operational advantages of the present invention, and the objectives achieved by the implementation of the present invention, reference must be made to the accompanying drawings illustrating preferred embodiments of the present invention and the contents described in the accompanying drawings.

[0021] The present invention will be described in detail below by explaining preferred embodiments of the invention with reference to the attached drawings. Identical reference numerals in each drawing indicate identical components.

[0022] FIG. 1 is a schematic drawing illustrating a metal window frame according to one embodiment of the present invention, FIG. 2 is a schematic cross-sectional view along line A-A' of FIG. 1, and FIG. 3 is an enlarged drawing illustrating a gap maintaining part shown in FIG. 2.

[0023] As illustrated in these drawings, the metal window (1) according to the present embodiment comprises a frame body (100) disposed in a structure (10), a window glass (110) coupled to the frame body (100), an elastic sealing part (200) disposed between the frame body (100) and the structure (10), and a gap maintaining part (300) which is supported on one side by the elastic sealing part (200) and supported on the other side by the frame body (100) to maintain a gap between the elastic sealing part (200) and the frame body (100).

[0024] The frame body (100) can be placed in a space provided in the structure (10).

[0025] The window glass (110) can be connected to the frame body (100) so as to be openable and closable through a separate frame.

[0026] The elastic sealing part (200) is interposed between the frame body (100) and the structure (10). This elastic sealing part (200) closes the gap between the structure (10) and the frame body (100) to prevent external air, moisture, dust, etc. from entering the interior, and performs the function of improving airtightness and waterproofness by absorbing changes in the gap that may occur due to thermal expansion or vibration.

[0027] The elastic sealing portion (200) includes a first sealing portion (210) arranged such that one side is supported by the structure (10) and the other side is supported by the frame body (100). This first sealing portion (210) is formed lengthwise along the contact surface between the structure (10) and the frame body (100) to form a basic sealing state and serves to secure initial airtightness performance when installing a window.

[0028] Additionally, a second sealing part (220) is provided on one side of the first sealing part (210) and extended in a curved manner. The second sealing part (220) has elastic restoring force according to its curved shape and serves to increase the flexibility of the entire sealing against minute movements of the structure (10) or external impacts.

[0029] In addition, a third sealing part (230) is extended and formed on one side of the second sealing part (220), which is again supported on the side of the structure (10). By the third sealing part (230) structurally forming a triple sealing structure together with the first sealing part (210) and the second sealing part (220), the inflow of external airflow, moisture, fine particles, etc. into the room can be blocked even more effectively.

[0030] Additionally, the first sealing part (210) is fixed to the frame body (100) through a fastening member (240) that is screw-fastened. This fastening member (240) increases the bonding strength between the first sealing part (210) and the frame body (100) during the installation of the window and serves to stably support the sealing part so that it does not detach during use, thereby improving the durability of the overall structure and long-term airtightness performance.

[0031] A gap maintaining member (300) is provided between the frame body (100) and the structure (10) to maintain a stable close contact even with external vibrations, thermal expansion, and minute movement of the structure (10). This gap maintaining member (300) secures a constant gap between the third sealing member (230) supported on the side of the structure (10) and the frame body (100), and performs the role of stably supporting each member through elastic support force.

[0032] The gap maintaining member (300) includes a gap maintaining body (310) and a first elastic support member (320) rotatably coupled to the gap maintaining body (310).

[0033] The gap maintaining body (310) is interposed in the space between the third sealing part (230) and the frame body (100) and is fixed to maintain the relative position between the two members at a reference gap. Additionally, a rotational support shaft (311) is formed inside so that the first elastic support part (320) can move fluidly according to rotational action.

[0034] The first elastic support member (320) includes a support member shaft (321) that is rotatably coupled by a pivot support shaft (311) formed in the gap maintaining body (310), and independent elastic support structures are provided at each end of the support member shaft (321).

[0035] A first cylinder (322) is mounted on one side of the support shaft (321), and a first support ball (323) movable in the axial direction is inserted inside the first cylinder (322). The first support ball (323) may be made of rubber or a synthetic resin with enhanced durability, and reacts sensitively to external loads or minute vibrations to absorb shock.

[0036] A first spring (324) is coupled to the first support ball (323) to provide elastic restoring force, and a first contact arm (325) is connected to the opposite end of the spring. One end of the first contact arm (325) contacts the third sealing part (230) and performs the function of elastically supporting the third sealing part (230).

[0037] This allows the third sealing part (230) to continuously maintain airtightness while moving in response to minute flow or vibration, even though it is fixed to the structure (10).

[0038] Meanwhile, a second cylinder (326) is provided on the other side of the support shaft (321), and a second support ball (327) and a second spring (328) are respectively mounted on the inside thereof.

[0039] The second support ball (327) is arranged to be elastically movable in the direction of the frame body (100), and the second spring (328) coupled thereto elastically supports the frame body (100) through the second contact arm (329).

[0040] The second contact arm (329) is positioned facing the first contact arm (325) and supports the frame body (100) with a flexible yet stable compressive force, so that the frame does not detach from the structure (10) or have any gaps even with external loads or installation errors.

[0041] The first contact arm (325) and the second contact arm (329) are additionally connected between them by a second elastic support member (330). This second elastic support member (330) consists of a support member (331) positioned in the center and a plurality of support springs (332) connecting the support member (331) to each contact arm.

[0042] The support spring (332) is designed to exert a restoring force against both compressive and tensile forces, absorbing vibrations of the contact arm and maintaining a balanced compression state between the third sealing part (230) and the frame body (100).

[0043] Additionally, the first contact arm (325) and the second contact arm (329) are each equipped with a magnetic member (340). This magnetic member (340) generates magnetic attraction toward each other, thereby maintaining a tighter contact state and preventing contact separation caused by external repeated vibrations or airflow. Since the magnetic force provides long-term fixing force independently of the mechanical spring, the sealing force of the seal does not decrease over time.

[0044] Furthermore, the magnetic member (340) provided in the first contact arm (325) can be coupled to the third sealing part (230) provided with a metal material, and the magnetic member (340) provided in the second contact arm (329) can be coupled by magnetic force to the frame body made of a metal material.

[0045] Consequently, the gap maintaining member (300) accurately maintains the gap between the third sealing member (230) and the frame body (100), while elastically supporting the separated sides in multiple directions through a plurality of springs (324, 328), support balls (323, 327), contact arms (325, 329), and magnetic members (340), thereby providing strong resistance to external environmental changes and offering structural advantages that improve airtightness, water resistance, and durability.

[0046] The metal window (1) according to the present invention is installed in an opening of a structure (10) and operates in a state that partitions the outside and the inside.

[0047] When installed, the frame body (100) is positioned so as to be in close contact with the structure (10), and at this time, an elastic sealing part (200) having a multi-stage structure is interposed between the frame body (100) and the structure (10).

[0048] First, the first sealing part (210) is positioned on the basic contact surface between the frame body (100) and the structure (10) and is installed in a supported state on the side of the structure (10). This first sealing part (210) is tightly sealed on both sides to maintain airtightness even after the frame body (100) is fixed, and is firmly fixed to the frame body (100) by a screw fastening member (240).

[0049] The second sealing part (220), which is formed in a curved shape on one side of the first sealing part (210), is compressed in the installed state and subsequently exerts elastic restoring force even against vibration, thermal expansion, and minute deformation of the structure (10) due to the external environment, thereby absorbing positional changes of the first sealing part (210) and the third sealing part (230).

[0050] The third sealing part (230), connected to one side of the second sealing part (220), is again supported by the structure (10), and together with the first sealing part (210), the sealing is formed into a double or triple structure to complete a multi-stage sealing structure.

[0051] In this state, the gap maintaining part (300) is positioned between the frame body (100) and the third sealing part (230) to maintain a constant gap while elastically supporting both.

[0052] The gap maintaining body (310) is fixed to the inside of the structure (10), and a first elastic support member (320) is rotatably coupled to the rotational support shaft (311) inside it. This first elastic support member (320) maintains the structural stability of the sealing part and the frame body (100) by responding fluidly even when the structure (10) moves slightly or vibrations are transmitted during use.

[0053] In actual use, the first cylinder (322) and the second cylinder (326) provided at both ends of the support shaft (321) move the first and second support balls (327), respectively, and the spring connected to the support ball provides a continuous restoring force to maintain the first contact arm (325) and the second contact arm (329) in a stable manner, thereby supporting the third sealing part (230) and the frame body (100).

[0054] This contact state is reinforced not only by the support spring (332) but also by the magnetic force of the magnetic member (340), and is maintained so that the contact force does not decrease even during long-term use.

[0055] In addition, the first contact arm (325) and the second contact arm (329) are further supported by the second elastic support member (330), and a support member (331) and a plurality of springs disposed between them actively respond to vibration and load changes to maintain a constant contact state. Through this, the airtightness, water resistance, and sound insulation performance of the internal space are stably maintained even under external environmental changes such as wind, rain, vibration, and high / low temperature changes during use.

[0056] In short, the metal window (1) according to the present invention can actively respond to physical changes in the structure (10) and environmental factors in actual use, and can effectively solve problems such as reduced airtightness, deterioration of sealing, and construction deviation that occurred in conventional metal windows (1) through a plurality of contact points, a multi-seal structure, and a composite elastic support mechanism.

[0057] As such, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the invention. Accordingly, such modified or varied embodiments should be deemed to fall within the scope of the claims of the present invention. Explanation of the symbols
