Description

Technical Field

[0001] The invention relates to the technical field of door and window accessories, in particular to an escape wind brace. Background Art

[0002] At present, more windows are equipped with wind braces to prevent the windows from closing automatically when the wind is strong. However, the wind braces can generally only limit the fixed opening angle and cannot be adjusted at will. When an emergency occurs and escape is required, the window cannot be removed from the window beam and must be dismantled with professional tools or violently. The disassembly is inconvenient, which not only destroys the original structure, but also delays time and affects people's escape.

[0003] The prior art provides a wind bracing structure that is convenient for escape, comprising a wind bracing arm and a slider installed on the window frame, the wind bracing arm and the slider being connected by a pin shaft with a groove, the wind bracing arm being provided with a locking assembly, the locking assembly being inserted into the groove of the pin shaft to prevent the pin shaft from accidentally detaching from the wind bracing arm and the slider, by controlling the locking assembly and then pulling out the pin shaft, the wind bracing arm can be separated from the slider, so that the opening angle of the window is not restricted, thereby facilitating people's escape. However, with the existing wind bracing structure, after the wind bracing arm and the slider are unlocked, the wind bracing arm forms a certain angle with the window sash, and the wind bracing arm extends out of the window sash. When people escape, they may collide with the wind bracing arm, and the wind bracing arm may cause injuries to people, which is not conducive to ensuring the safety of people when escaping. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an escape wind brace to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The solution of the present invention to solve its technical problem is:

[0006] Escape wind bracing, including:

[0007] A window frame slider, wherein the window frame slider is provided with a first plug hole;

[0008] A wind bracing arm, wherein two ends of the wind bracing arm are respectively provided with a first hinged end and a second hinged end, and the second hinged end is provided with a second plug hole;

[0009] A window sash connecting member, the window sash connecting member is hingedly connected to the first hinged end, a swing elastic member is provided between the window sash connecting member and the wind bracing arm, the swing elastic member enables the wind bracing arm to always have a tendency to swing toward the window sash;

[0010] A latch body, the latch body being inserted into the first plug hole and the second plug hole, the latch body being provided with a locking ring groove;

[0011] A locking structure, wherein the locking structure is slidably connected to the wind bracing arm, and the front end of the locking structure is inserted into the locking ring groove.

[0012] Through the above technical solution, when people need to escape, they first push the window open, and then drive the locking structure to move in the direction away from the latch body. When the latch limit portion of the locking structure is completely out of the locking ring groove, the user drives the latch drive plate to move, so that the latch body leaves the first plug hole. Then, due to the elastic force of the swinging elastic member, the wind brace arm will swing toward the window sash, so that the wind brace arm is automatically retracted. After the wind brace arm is automatically retracted, it can avoid the wind brace arm from colliding with the escaping people, thereby avoiding people from being injured due to the collision with the wind brace arm, which can effectively improve the safety of people when escaping.

[0013] As a further improvement of the above technical solution, it also includes a mounting profile, the window frame slider is slidably installed in the mounting profile, and both ends of the mounting profile are respectively provided with mounting through holes.

[0014] As a further improvement of the above technical solution, slider limiting protrusions are respectively provided at both ends of the mounting profile.

[0015] Through the above technical solution, the slider limiting protrusion is used to limit the sliding position of the window frame slider to prevent the window frame slider from separating from the mounting profile.

[0016] As a further improvement of the above technical solution, the window frame slider is installed with a damping adjustment structure, which includes an adjustment screw and a damping block. The adjustment screw is threadedly connected to the window frame slider, and the adjustment screw abuts against the damping block.

[0017] Through the above technical solution, when the adjusting screw is turned so that the tail end of the adjusting screw is close to the mounting profile, the friction between the damping block and the mounting profile increases, thereby playing a role in adjusting the damping of the window frame slider.

[0018] As a further improvement of the above technical solution, the window frame slider is provided with a latch driving elastic member, and the latch driving elastic member enables the latch body to always have a tendency to move away from the window frame slider.

[0019] As a further improvement of the above technical solution, the window frame slider is equipped with a latch driving piece, both ends of the latch driving elastic member are respectively fixedly connected to the latch driving piece and the window frame slider, and the latch driving piece abuts against the end of the latch body.

[0020] Through the above technical solution, when people need to escape, they first push the window open, and then drive the locking structure to move in the direction away from the latch body. When the latch limit part of the locking structure is completely out of the locking ring groove, the latch drive elastic member drives the latch drive plate to move, and the latch drive plate drives the latch body to pop out of the first plug hole, so that after the locking structure is released from the latch body, the latch body can automatically pop out, which can reduce the operating steps of the escapee and the time required for escape, so as to further reduce the risk of injury.

[0021] As a further improvement of the above technical solution, the latch drive plate is provided with at least two position limiting parts, and a plurality of the position limiting parts are evenly arranged on the latch drive plate. The window frame slider is provided with a position limiting groove, and the position limiting part slides in the position limiting groove.

[0022] As a further improvement of the above technical solution, the latch driving elastic member is arranged in the position limiting groove.

[0023] As a further improvement of the above technical solution, a first magnetic member is provided at the end of the latch body, and a second magnetic member is provided at the second hinged end, and the first magnetic member and the second magnetic member are magnetically connected.

[0024] With the above technical solution, after the latch body pops out of the first socket, due to the magnetic force of the second magnetic member and the first magnetic member, the latch body remains out of the first socket to prevent the latch body from re-entering the first socket after popping out.

[0025] As a further improvement of the above technical solution, the latch body is connected to the wind bracing arm via a connecting rope.

[0026] Through the above technical solution, the connecting rope can prevent the pin body from being lost.

[0027] The beneficial effect of the present invention is that it can effectively improve the safety of people when escaping.

[0028] The invention is used in the technical field of door and window accessories. BRIEF DESCRIPTION OF THE DRAWINGS

The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0036] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] In the description of the present invention, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0038] In the prior art, there is a wind bracing structure that is convenient for escape, including a wind bracing arm and a slider installed on the window frame, the wind bracing arm and the slider are connected by a pin shaft with a groove, and the wind bracing arm is provided with a locking assembly, which is inserted into the groove of the pin shaft to prevent the pin shaft from accidentally detaching from the wind bracing arm and the slider. By controlling the locking assembly and then pulling out the pin shaft, the wind bracing arm can be separated from the slider, so that the opening angle of the window is not restricted, thereby facilitating people's escape. However, in the existing wind bracing structure, after the wind bracing arm and the slider are unlocked, the wind bracing arm and the window sash are at a certain angle, and the wind bracing arm extends out of the window sash. When people escape, they may collide with the wind bracing arm, and the wind bracing arm may cause injuries to people, which is not conducive to ensuring the safety of people when escaping. Therefore, the wind bracing structure that is convenient for escape in the prior art is improved to form the present scheme, which is described in detail below.

[0039] Reference Figures 1 to 4 The escape wind brace includes a window frame slider 100, a wind brace arm 200, a window sash connector 300, a mounting profile 400, a latch body 500 and a locking structure 600.

[0040] The mounting profile 400 is fixedly installed in the hardware fitting mounting groove of the window frame. Specifically, the mounting profile 400 is a C-shaped profile structure. The mounting profile 400 is formed with a sliding groove for the window frame slider 100 to slide. The window frame slider 100 is slidably installed on the mounting profile 400. Both ends of the window frame slider 100 are protruding with sliding parts 170. The sliding part 170 is arranged in the sliding groove, and the upper end surface of the sliding part 170 is limited by the top wall of the mounting profile 400.

[0041] Both ends of the mounting profile 400 are provided with mounting holes 410, which are set as waist-shaped hole structures. The mounting holes 410 are used to pass screws through the mounting profile 400, and the mounting profile 400 is fixed to the window frame by screws. Both ends of the mounting profile 400 are also provided with slider limit protrusions 420, which are formed by punching a punching machine, and the slider limit protrusions 420 are used to limit the sliding position of the window frame slider 100 to prevent the window frame slider 100 from separating from the mounting profile 400.

[0042] Specifically, in this embodiment, the window frame slider 100 is provided with a damping adjustment structure, which includes a damping block 120 and an adjusting screw 110. The adjusting screw 110 passes through the window frame slider 100 and is threadedly connected with the window frame slider 100. The head of the adjusting screw 110 is provided with anti-skid patterns. By providing the anti-skid patterns on the head of the adjusting screw 110, the probability of slipping when people turn the adjusting screw 110 by hand can be reduced. The damping block 120 is provided between the mounting profile 400 and the adjusting screw 110. When the adjusting screw 110 is turned so that the tail end of the adjusting screw 110 is close to the mounting profile 400, the friction between the damping block 120 and the mounting profile 400 increases, thereby playing a role in adjusting the damping of the window frame slider 100.

[0043] Specifically, the window frame slider 100 defines a first insertion hole 130 .

[0044] Through holes are respectively provided at both ends of the window sash connector 300 for screws to pass through, and the window sash connector 300 is fixedly connected to the window sash by screws.

[0045] The two ends of the wind bracing arm 200 are respectively provided with a second hinged end 202 and a first hinged end 201. The second hinged end 202 is provided with a second plug hole 220, and the second plug hole 220 is provided corresponding to the first plug hole 130. The first hinged end 201 is hingedly connected to the window sash connector 300.

[0046] Specifically, in this embodiment, a swinging elastic member (the swinging elastic member is not shown in the figure) is arranged between the wind bracing arm 200 and the window sash connecting member 300. The swinging elastic member is configured as a torsion spring. The two ends of the swinging elastic member are respectively connected to the wind bracing arm 200 and the window sash connecting member 300. The swinging elastic member enables the wind bracing arm 200 to always have a tendency to swing toward the window sash.

[0047] In normal use, the latch body 500 is inserted into the second insertion hole 220 and the first insertion hole 130, and the latch body 500 serves as a hinge axis between the wind support arm 200 and the window frame slider 100. A locking ring groove 520 is provided at the end of the latch body 500.

[0048] Specifically, in this embodiment, a first magnetic member 510 is fixedly provided at the end of the latch body 500, and a second magnetic member 240 is fixedly provided at the second hinged end 202, and the second magnetic member 240 and the first magnetic member 510 are magnetically connected. Specifically, in this embodiment, the first magnetic member 510 is set as a permanent magnet, and the second magnetic member 240 is set as a soft magnet. In other embodiments, the second magnetic member 240 may be set as a permanent magnet, and the first magnetic member 510 may be set as a soft magnet, or both the second magnetic member 240 and the first magnetic member 510 may be set as permanent magnets. Those skilled in the art may select the second magnetic member 240 and the first magnetic member 510 according to actual needs.

[0049] By providing the second magnetic member 240 and the first magnetic member 510 , the latch body 500 can be prevented from being separated from the wind support arm 200 to a certain extent.

[0050] Specifically, in this embodiment, a connecting rope 230 is provided between the latch body 500 and the wind bracing arm 200, and the wind bracing arm 200 and the latch body 500 are connected by the connecting rope 230. The latch body 500 and the wind bracing arm 200 are connected by the connecting rope 230, so that the latch body 500 is prevented from being lost after being separated from the wind bracing arm 200 during escape, thereby ensuring the integrity of the wind bracing structure.

[0051] The locking structure 600 is slidably connected to the wind bracing arm 200, and a latch limiting portion 610 is provided at one end of the locking structure 600 close to the latch body 500. The number of the latch limiting portions 610 is set to two, and the two latch limiting portions 610 are arranged opposite to each other. The two latch limiting portions 610 are inserted into the locking ring groove 520 to lock the latch body 500.

[0052] Specifically, in this embodiment, a latch drive elastic member 140 and a latch drive sheet 150 are provided in the window frame slider 100. The latch drive elastic member 140 is provided as a spring, and both ends of the latch drive elastic member 140 are respectively fixedly connected to the latch drive sheet 150 and the window frame slider 100, and the latch drive elastic member 140 makes the latch drive sheet 150 always have a tendency to move away from the window frame slider 100 and toward the wind bracing arm 200.

[0053] Position limiting parts 151 are respectively provided at both ends of the window frame slider 100. In other embodiments, the number of position limiting parts 151 can also be set to three, four, etc. Those skilled in the art can select the number of position limiting parts 151 according to actual needs. A position limiting groove 160 is provided on the window frame slider 100. The position limiting part 151 is arranged in the position limiting groove 160, and the position limiting part 151 is slidably connected with the position limiting groove 160. The position limiting groove 160 can limit the position limiting part 151 to prevent the latch drive sheet 150 from being driven by the latch drive elastic member 140 and detaching from the window frame slider 100, so as to ensure the structural integrity of the escape wind brace. Specifically, the latch drive elastic member 140 is also arranged in the position limiting groove 160.

[0054] When people need to escape, they first push open the window and then drive the locking structure 600 to move in a direction away from the latch body 500. When the latch limiting portion 610 of the locking structure 600 is completely out of the locking ring groove 520, the latch driving elastic member 140 drives the latch driving plate 150 to move, and the latch driving plate 150 drives the latch body 500 to pop out of the first plug hole 130. After the latch body 500 pops out of the first plug hole 130, due to the magnetic force of the second magnetic member 240 and the first magnetic member 510, the latch body 500 remains in a state of being out of the first plug hole 130, and due to the elastic force of the swinging elastic member, the wind bracing arm 200 will swing toward the window sash, so that the wind bracing arm 200 is automatically retracted. After the wind bracing arm 200 is automatically retracted, the wind bracing arm 200 can be prevented from colliding with the escaping people, thereby preventing people from being injured due to the collision with the wind bracing arm 200, which can effectively improve the safety of people when escaping.
