Description

Technical Field

[0001] This invention relates to the field of window technology, and more particularly to a multifunctional security window. Background Technology

[0002] Security windows, as common building accessories, are widely used in residences, office buildings, and other places. Their main functions are to prevent theft, ensure indoor security, and also accommodate ventilation and lighting needs. Currently, most security windows on the market are fixed structures, made of metal bars or mesh materials, and directly installed on the exterior wall of the building. While this design provides some degree of security, in emergencies such as fires, fixed security windows often become "cages" hindering escape, preventing people from evacuating through the windows in time and making it difficult for rescuers to reach them from the outside. In recent years, there have been several tragedies caused by security windows obstructing escape routes.

[0003] Some existing technologies have proposed burglar bars with escape functions. For example, some products have openable escape doors on the burglar bars and are equipped with folding or telescopic escape ladders. In an emergency, people can open the escape door, lower the ladder and escape down the exterior wall. However, in actual use, the escape ladders are not very stable and are prone to shaking or falling during the climbing process, posing a high safety risk. Moreover, for some tall buildings, the use of escape ladders is not practical. Therefore, there is an urgent need at present for a multi-functional burglar bar that can meet daily burglar protection needs and provide a safe refuge space in the event of a disaster. Summary of the Invention

[0004] The present invention aims to provide a multifunctional security window to solve the problem that current security windows cannot provide a safe refuge space.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-functional security window includes a lower frame, an upper frame, and a fixing part;

[0007] The lower frame is equipped with guardrail mesh and several sliding grooves. The sliders on the side of the guardrail mesh are slidably installed in the corresponding sliding grooves to guide the guardrail mesh to slide along the sliding grooves. The guardrail mesh is equipped with a locking group to lock the guardrail mesh in the lower frame.

[0008] The upper frame is located above the lower frame. A vertical rod is hinged to the bottom of the upper frame. The bottom end of the vertical rod is detachably connected to the lower frame. Round shafts are provided on both sides of the lower frame and the upper frame, and the round shafts are embedded in the fixing part.

[0009] Two sets of fixing parts are arranged opposite each other and installed on the exterior wall of the building to fix the lower frame and the upper frame. The fixing parts are provided with limiting grooves and inclined grooves. There are two sets of inclined grooves, located at the bottom and top of the fixing parts respectively, and both are connected to the limiting grooves. Each round shaft is located in the corresponding inclined groove. The fixing parts are provided with limiting components to limit the position of the round shaft in the inclined groove at the top of the fixing parts.

[0010] Furthermore, the locking assembly includes a handle and a rack. A gear is provided at the bottom of the handle, which meshes with the rack to drive the rack to move. The end of the rack passes through the guardrail mesh and is locked inside the lower frame.

[0011] Furthermore, a connecting seat is provided on the lower frame, the bottom end of the vertical rod is located inside the connecting seat, and the two are connected by a pin.

[0012] Furthermore, the connecting seat is located at the bottom of one set of grooves.

[0013] Furthermore, the limiting component includes a baffle and a stop block. The baffle is slidably disposed in the fixed part, with its top end located in the inclined groove at the top of the fixed part and in contact with the round shaft at the top of the upper frame. The bottom end of the baffle is in contact with the top surface of the stop block, and the stop block is slidably disposed in the placement groove on the fixed part.

[0014] Furthermore, a cover plate is provided at the opening of the placement slot.

[0015] Furthermore, both the lower and upper frames are made of stainless steel.

[0016] The principles and beneficial effects of the technical solution are as follows:

[0017] This invention provides a multifunctional anti-theft window.

[0018] 1. After releasing the connection of the vertical bar and the locking group, lift the guardrail upwards and move it to the top of the lower frame. Push the lower frame outwards. Under the action of gravity, the round shaft of the lower frame slides from the inclined groove to the bottom of the limiting groove, causing the lower frame to flip outwards and form a support platform. The disaster victim enters the flipped lower frame, takes out the limiting component, releases the restriction on the round shaft of the upper frame, and lets it slide from the inclined groove into the limiting groove and move downwards. The disaster victim holds the vertical bar, so that the upper frame rotates upwards when it moves downwards, thereby fastening it to the lower frame to form a safe shelter, providing a safe refuge space for the disaster victim.

[0019] 2. Move the guardrail to the top of the lower frame. After the lower frame is flipped outward by 90°, the guardrail is on the outermost side, which serves as a guardrail, improves safety, and makes it easier for disaster victims to enter the flipped lower frame, thus increasing the speed of disaster victims' evacuation.

[0020] 3. The upper and lower frames are connected as a whole by vertical bars. The sliding guardrail is normally locked at the bottom of the lower frame to form a closed burglarproof window. All operating parts are integrated into the frame, making the burglarproof window no different from an ordinary burglarproof window, meeting daily needs such as burglarproof, fall prevention, ventilation, and lighting.

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0036] like Figures 1-13 As shown, a multi-functional security window includes a lower frame 1, an upper frame 2, and a fixing part 3; both the lower frame 1 and the upper frame 2 are rectangular metal frames.

[0037] The lower frame 1 is provided with a guardrail mesh 101 and several sliding grooves 102. The guardrail mesh 101 is a metal grid structure, which can both allow ventilation and light to pass through, and also serve as a protective function. The sliders on the side of the guardrail mesh 101 are slidably installed in the corresponding sliding grooves 102. The sliding grooves 102 extend along the vertical direction of the lower frame 1 and are used to guide the guardrail mesh 101 to slide along the sliding grooves 102. The guardrail mesh 101 is provided with a locking group 103, which is used to lock the guardrail mesh 101 at the bottom (normal state) or top (disaster state) of the lower frame 1.

[0038] The upper frame 2 is located above the lower frame 1. A vertical rod 201 is hinged to the bottom of the upper frame 2. The bottom end of the vertical rod 201 is detachably connected to the lower frame 1, so that when the vertical rod 201 is connected, the upper frame 1 and the lower frame 2 form a whole anti-theft window. Both sides of the lower frame 1 and the upper frame 2 are provided with round shafts 4, which are embedded in the fixing part 3. The round shafts 4 are made of solid stainless steel rods and are welded to the frame.

[0039] Two sets of fixing parts 3 are arranged opposite each other. They are made of stainless steel plates and are fixed to both sides of the window opening on the exterior wall of the building by expansion bolts. They are used to fix the lower frame 1 and the upper frame 2. The fixing parts 3 are provided with limiting grooves 301 and inclined grooves 302. Two sets of inclined grooves 302 are provided, located at the bottom and top of the fixing parts 3 respectively, and both of them are connected to the limiting grooves 301.

[0040] The round shafts 4 on both sides of the lower frame 1 are located at its bottom corners and are fitted into the inclined grooves 302 at the bottom of the fixing part 3. After the lower frame 1 is unlocked, the round shafts 4 can slide from the inclined grooves 302 into the limiting grooves 301, thereby causing the lower frame 1 to rotate until the side of the lower frame 1 contacts the outer wall. At this time, the lower frame 1 rotates outward by 90°. The round shafts 4 on both sides of the upper frame 2 are located at its top corners and are fitted into the inclined grooves 302 at the top of the fixing part 3. The fixing part 3 is provided with a limiting component to limit the position of the round shafts 4 in the inclined grooves 302 at the top of the fixing part 3, preventing them from sliding out of the inclined grooves 302 and into the limiting grooves 301, thereby making the burglarproof window composed of the upper frame 2 and the lower frame 1 stably fixed at the window opening.

[0041] In normal conditions, the vertical bar 201 connects the upper frame 1 and the lower frame 2, forming a single burglarproof window located outside the window opening for security. In case of emergencies such as fire requiring evacuation, the person in distress disconnects the bottom of the vertical bar 201 from the lower frame 1, then rotates the locking assembly 103 to release the lock on the guardrail 101. They then pull the guardrail 101 upwards along the slide groove 102, moving it to the top of the lower frame 1. The locking assembly 103 is then rotated back to lock the guardrail 101 at the top of the lower frame 1. At this point, the person in distress pushes the lower frame 1 outwards, causing the round shaft 4 at the bottom of the lower frame 1 to slide downwards within the inclined groove 302 at the bottom of the fixing part 3, entering the limiting groove 301 and moving towards the bottom of the limiting groove 301. This movement of the round shaft 4, located at the bottom corner of the lower frame 1, further contributes to the security. When the lower frame 1 moves downward, it automatically flips outward under the action of gravity until the side of the lower frame 1 contacts the outer wall. At this time, the lower frame 1 has just flipped 90°, forming a horizontal support platform. The disaster victim enters the flipped lower frame 1 and operates the limiting component on the fixing part 3 to release the restriction on the top circular shaft 4 of the upper frame 2. This allows the circular shaft 4 to slide downward in the inclined groove 302 at the top of the fixing part 3 and enter the limiting groove 301, thereby driving the upper frame 2 to move downward. At the same time, the disaster victim holds the bottom end of the vertical pole 201 and tilts it to support the bottom of the upper frame 2. As the upper frame 2 moves downward, it flips upward and finally locks onto the lower frame 1, forming a safe house. This provides a safe refuge space for the disaster victim to lie in and wait for fire rescue, reducing the impact of indoor smoke on the disaster victim.

[0042] In this embodiment, the locking assembly 103 includes a rotatable handle 1031 and a movable rack 1033. A gear 1032 is located at the bottom of the handle 1031, meshing with the rack 1033 to move the rack 1033. The end of the rack 1033 extends through the guardrail mesh 101 and engages in a positioning hole at the bottom or top of the lower frame 1. By rotating the handle 1031, the gear 1032 rotates, thereby moving the rack 1033, causing it to extend or retract into the guardrail mesh 101, thus achieving locking and unlocking of the guardrail mesh 101. This design is convenient to operate, simple in structure, and highly reliable.

[0043] In this embodiment, a connecting seat 104 is provided on the lower frame 1, and the bottom end of the vertical rod 201 is located inside the connecting seat 104. The vertical rod 201 is aligned with the pin hole on the connecting seat 104, and the two are connected together by a pin. Alternatively, a padlock, as used in the prior art, can be used to pass through the pin hole to connect the two, thereby improving security. By removing the pin or padlock, the connection between the vertical rod 201 and the connecting seat 104 can be released, so that the lower frame 1 and the upper frame 2 can move independently.

[0044] In this embodiment, the connecting seat 104 is located at the bottom of one set of sliding grooves 102. When the vertical rod 201 is connected to the connecting seat 104, the vertical rod 201 covers the sliding groove 102 where the connecting seat 104 is located, thereby preventing the guardrail 101 from sliding upward and preventing criminals from opening the guardrail 101.

[0045] In this embodiment, the limiting component includes a baffle 304 and a stop 306. The baffle 304 is slidably disposed within the fixing part 3, with its top end located within the inclined groove 302 at the top of the fixing part 3 and in contact with the round shaft 4 at the top of the upper frame 2, thus preventing the movement of the round shaft 4. The bottom end of the baffle 304 is in contact with the top surface of the stop 306, and the stop 306 is slidably disposed within the placement groove 305 on the fixing part 3. After the stop 306 is removed from the placement groove 305, the baffle 304 loses the obstruction of the stop 306 and slides downward under the action of gravity, thereby causing its top end to exit the inclined groove 302 at the top of the fixing part 3, thus no longer obstructing the round shaft 4 within the inclined groove 302, facilitating subsequent movement of the upper frame 2.

[0046] In this embodiment, a cover plate 303 is provided at the opening of the placement slot 305. The cover plate 303 can close the opening of the placement slot 305 to prevent debris from entering the placement slot 305 and affecting the removal of the stop block 306. In use, the opening of the placement slot 305 can be opened by flipping the cover plate 303 upward.

[0047] In this embodiment, both the lower frame 1 and the upper frame 2 are made of stainless steel. Both the lower frame 1 and the upper frame 2 are formed by welding stainless steel square tubing. After the welds are ground smooth, they undergo pickling and passivation treatment to ensure good weather resistance and corrosion resistance, giving the security window sufficient strength.

[0048] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific technical solutions or characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
