Description

Technical Field

[0001] This invention relates to a special accessory for fire-resistant windows and fireproof windows, specifically a method and mechanism for automatically closing and locking outdoor windows in case of fire. Background Technology

[0002] According to Section 8.13.2 of the national standard for fireproof windows, GB16809-2008, if the fireproof window sash reliably closes automatically within 60 seconds (inclusive) of the start of the fire resistance test while in the open state, the fire resistance test can continue; otherwise, the fire resistance test can be stopped.

[0003] Currently, there are two types of products on the market that can automatically close windows:

[0004] One product is a scaled-down version of a door closer applied to windows. Its disadvantages are: first, opening and closing the window requires a force greater than the door closer's damping force, limiting its use by women and children; second, the internal structure of this type of window closer generally contains grease, which can easily ignite or explode in a fire; third, this fire-activated self-closing device cannot meet the needs of everyday window use, allowing only a limited opening angle (only one angle), and the self-closing mechanism only functions when the window is opened to this specific angle in case of an external fire; fourth, this structure cannot be applied to inward-opening tilt-and-turn or outward-opening bottom-hung windows, thus having certain limitations.

[0005] Another type of product uses a spring-loaded energy storage structure for its automatic window closing mechanism in case of fire, which prevents secondary combustion and explosion during a fire. However, the activation device of the temperature sensor is limited to the window frame, and the fire temperature cannot be transmitted to the activation device of the temperature sensor in time. Therefore, when it is necessary to automatically close the window in time in case of a fire outside the window, the window may not close in time or may fail to close.

[0006] In summary, the existing automatic window locking structures on the market in the event of an external fire share the following drawbacks: after automatically closing the window, they do not utilize the window's own locking mechanism, but instead rely on a specially added latch mechanism. Even if this latch mechanism ensures a tight and secure closing of the window, its timely closing rate is not 100%. This is due to structural defects. If the window closing rate were 100%, the tightness between the window frame and the window sash would be sacrificed, allowing smoke and fire to enter the room through any gaps.

[0007] Currently, fire-resistant window closing mechanisms on the market generally suffer from incomplete closure and poor sealing after the window is closed in case of fire. Smoke and fire can still enter the room through insufficient gaps. The reason for this defect is that current products on the market do not effectively utilize the window's own locking mechanism. Summary of the Invention

[0008] The technical objective of this invention is to address the shortcomings of existing technologies by providing a design that is reasonable, structurally simple, and

[0009] An automatic window closing and locking method and mechanism that can achieve both automatic window closing in case of fire outdoors and automatic locking when the window is closed.

[0010] The technical solution adopted by this invention to solve its technical problem is:

[0011] An automatic window closing and locking method for outdoor windows in case of fire includes two main steps: first, automatically closing the open window sash when a fire occurs; and second, locking the closed window sash to the window frame.

[0012] The steps for automatically closing open window sashes include:

[0013] An energy storage device that can control the automatic closing of window sashes;

[0014] A low-temperature sensing excitation device that can control the operation of an energy storage device;

[0015] The aforementioned low-temperature sensing excitation device uses low-temperature sensing excitation components as the determining factor for whether a fire has occurred. It also excites the transmission mechanism through a bursting motion, thereby controlling the energy storage device to operate. The steel cable of the energy storage device pulls the window sash to achieve the purpose of automatically closing the window in the event of a fire.

[0016] The steps for locking the closed window sash to the window frame include:

[0017] An energy storage transmission device that can control the rotation of the window via the handle's square shaft;

[0018] A high-temperature induction device that can control the operation of an energy storage transmission device;

[0019] The aforementioned high-temperature excitation device uses a high-temperature sensing element as a judgment element for whether a fire has occurred, and excites the transmission mechanism through an explosion, thereby controlling the operation of the energy storage transmission device. The energy storage transmission device converts its stored potential energy into kinetic energy, causing the window handle square shaft to rotate to achieve the purpose of automatically locking the window when it is closed in the event of a fire.

[0020] Furthermore, a safety device is installed on the inner side of the window sash. This safety device is connected to a steel cable of the energy storage device, enabling the window sash to automatically close and reopen. Without the safety device, the window sash would be difficult to reopen after automatically closing due to the action of the energy storage device.

[0021] Furthermore, the mechanism includes an automatic window closing mechanism and an automatic locking mechanism in the closed window state;

[0022] The automatic window closing mechanism includes an energy storage device and a low-temperature sensing excitation device. The energy storage device includes an energy storage base and an energy storage shell. The energy storage shell is installed on the energy storage base to form an energy storage cavity. A coil spring fixing shaft is provided on the energy storage cavity. A coil spring and a steel cable transmission disk are provided on the coil spring fixing shaft. A steel cable is provided on the steel cable transmission disk. An excitation hole is opened on the side of the steel cable transmission disk near the energy storage base. The steel cable is led outward from the lead hole of the energy storage shell. The low-temperature sensing excitation device includes a low-temperature sensing excitation fixing seat installed on the energy storage base and a low-temperature sensing excitation protective shell installed on the low-temperature sensing excitation fixing seat. A low-temperature sensing excitation pin is provided inside the low-temperature sensing excitation protective shell. The thin end of the low-temperature sensing excitation pin passes through the energy storage base and extends into the excitation hole of the steel cable transmission disk. A low-temperature sensing spring is provided between the low-temperature sensing excitation fixing seat and the low-temperature sensing excitation pin. A low-temperature sensing excitation element is provided between the thick end of the low-temperature sensing excitation pin and the tail of the low-temperature sensing excitation protective shell.

[0023] The automatic locking mechanism in the closed window state includes an energy storage transmission device and a high-temperature sensing excitation device. The high-temperature sensing excitation device includes a high-temperature sensing excitation mounting base installed on the energy storage transmission device and a high-temperature sensing excitation protective shell installed on the high-temperature sensing excitation mounting base. A high-temperature sensing excitation pin is provided inside the high-temperature sensing excitation protective shell. One end of the high-temperature sensing excitation pin passes through the window sash and the energy storage transmission shell and extends into the bottom of the spring mounting base. The other end of the high-temperature sensing excitation pin is acted on the high-temperature sensing spring, and at the same time, under the action of the spring, it abuts against the high-temperature sensing excitation element. The high-temperature sensing excitation element is provided between the tail ends of the high-temperature sensing excitation protective shell.

[0024] The above-mentioned energy storage transmission device has two structural forms:

[0025] The first structural form: The energy storage transmission device includes an energy storage transmission housing and a limiting pin, a compression spring, a spring fixing seat, a rack, and a gear disposed within the energy storage transmission housing. The limiting pin is located at the upper part of the energy storage transmission housing, and a compression spring is located at the lower part of the limiting pin. The compression spring is mounted on the spring fixing seat located below it. The bottom of the spring fixing seat is movably connected to the high-temperature sensing pin of the high-temperature sensing device. A rack is longitudinally disposed below the spring fixing seat, and there is a normal working clearance between the spring fixing seat and the rack. The rack meshes with a gear disposed on the square shaft of the window handle. The size of this working clearance must ensure that when the handle is in normal use, rotating the handle will cause the window handle square shaft and the gear to rotate together. The rotation of the gear will cause the rack to reciprocate up and down within the energy storage transmission device. When the rack is at its highest point, it must not contact the spring fixing seat.

[0026] The second type: The energy storage transmission device includes an energy storage transmission housing and a limiting pin, a compression spring, a spring fixing seat, and a transmission plate disposed within the energy storage transmission housing. The limiting pin is located at the lower part of the energy storage transmission housing. A compression spring is located above the limiting pin, and a spring fixing seat is located above the compression spring. The upper part of the spring fixing seat is movably connected to the high-temperature sensing pin of the high-temperature sensing device. A transmission plate is located above the spring fixing seat, and there is a normal working clearance between the spring fixing seat and the transmission plate. The transmission plate is connected to a shift pin disposed on the transmission plate. The size of this working clearance must ensure that when the handle is in normal use, rotating the handle will cause the shift pin to drive the transmission plate to move up and down reciprocatingly. When the transmission plate is at its lowest point, it should not contact the spring fixing seat.

[0027] The handle will cause the window handle square shaft and gear to rotate together. The rotation of the gear will cause the rack to move up and down in the energy storage transmission device. When the rack is at the top, it must not touch the spring fixing seat.

[0028] Furthermore, the mechanism also includes a safety device connected to the steel cable. The safety device includes a fixing pin, a flat pad, a safety pin, a ring, a rubber ring, and an anti-disengagement sleeve. The outer end of the fixing pin is connected to the steel cable and is fitted with a rubber ring. The inner end of the fixing pin is movably connected to the safety pin. One end of the safety pin is provided with a ring, and the other end of the safety pin is provided with an anti-disengagement sleeve. A flat pad is fitted on the inner end of the fixing pin.

[0029] Furthermore, both the low-temperature sensing device and the high-temperature sensing device are fire-fighting temperature-sensing glass bulbs or metal temperature-sensing bodies.

[0030] Preferably, the low-temperature excitation element of the low-temperature excitation device is a fire-fighting heat-sensing glass bulb with a temperature of 68°C, and the high-temperature excitation element of the high-temperature excitation device is a fire-fighting heat-sensing glass bulb with a temperature of 93°C-141°C.

[0031] This invention utilizes both a low-temperature sensing device and a high-temperature sensing device to automatically close open windows in the event of a fire, and then lock the closed windows to the window frame. If the window is closed when a fire occurs, the operation of closing and then locking is not affected.

[0032] The advantages of the automatic locking mechanism of the present invention when the window is closed during a fire, compared with the prior art, are as follows:

[0033] (1) The opening and closing force of the present invention is no different from that of conventional windows, and can be used normally by women, children and infants.

[0034] (2) The present invention places the temperature sensing detonation device outside the window. Its internal structure adopts the principle of spring energy storage. When a fire is formed, the mechanism will not explode. Moreover, the mechanism eliminates complex structures such as hydraulic seals, is easy to manufacture, has low cost, can be maintenance-free for life, and is reliable and simple.

[0035] (3) This invention can be opened at any angle in daily life.

[0036] (4) This invention is applicable to various window opening methods, such as inward opening, outward opening, inward opening and tilting, outward opening and bottom hanging, etc.

[0037] (5) The temperature-sensing excitation structure of the present invention is exposed outside the window, which improves the efficiency and effectively avoids the problem of potential excitation failure due to improper position of the temperature-sensing excitation device.

[0038] (6) The present invention is reasonably designed and has a simple structure. By abandoning the latch structure for closing windows on the market, it eliminates the shortcomings of the current window closing mechanism, which is not tight and not airtight. This avoids the possibility of smoke and fire entering the room when a fire occurs, and truly realizes the basic requirement of fire prevention and refuge. Attached Figure Description
