Description

Technical Field

[0001] This application relates to the field of mechanical technology, and particularly relates to a safety door and window. Background Art

[0002] In the construction field, especially in commercial building areas, a considerable part of the exterior wall doors and windows are hinged doors and windows with the lower edge pushed outwards. Such doors and windows not only avoid the inward folding of the doors and windows occupying the indoor space, but also to a certain extent avoid rainwater from pouring into the house.

[0003] However, such doors and windows generally have the following problems:

[0004] 1. When the window is closed, due to reasons such as the self-weight of the window and the excessive force exerted by the user when closing the window, the window impacts the window frame at the moment of closing, generating relatively large noise and mechanical wear, and also avoiding damage to items accidentally placed under the lower edge of the window frame assembly or the user's hand.

[0005] 2. Some doors and windows have too large an opening and closing angle, which easily leads to safety problems such as children falling. Summary of the Invention

[0006] A safety door and window, comprising:

[0007] A window frame assembly, fixed to the building foundation;

[0008] A connecting rod assembly, arranged on the window frame assembly;

[0009] A flipping window body, arranged on the connecting rod assembly, and the lower edge of the flipping window body is arranged to flip forward;

[0010] A buffer assembly, arranged above the connecting rod assembly, for absorbing the kinetic energy when the flipping window body closes quickly.

[0011] As a further embodiment:

[0012] The window frame assembly includes a rectangular frame connected and formed in four directions of up, down, left, and right, and a rectangular bottom frame is formed inward in the plane on the rear end surface of the rectangular frame. A rectangular sealing bottom frame is provided at the front end of the rectangular bottom frame;

[0013] There are a pair of the connecting rod assemblies. A connecting rod assembly is respectively provided on the left and right side edges of the rectangular frame. The connecting rod assembly includes:

[0014] A fixed slide rail, fixedly arranged on the left or right side of the rectangular frame. A sliding track is provided on the inner wall of the fixed slide rail, and an anti-detachment opening with a narrowed width is provided on the a side of the sliding track;

[0015] An articulated base, slidably arranged in the fixed slide rail. An upper articulated arm is articulated above the articulated base, and an articulated connecting rod is articulated below the articulated base;

[0016] The lower articulated arm is articulated to the left or right side of the rectangular frame.

[0017] The flipping window form at least includes flipping frames connected and formed in the four directions of up, down, left, and right, and a rectangular glass arranged at the front end of the flipping frame. The side of the flipping frame is articulated to the distal end of the lower articulated arm and the distal end of the upper articulated arm.

[0018] As a further implementation scheme:

[0019] A handle is arranged at the lower side of the flipping frame.

[0020] There are a pair of the buffer assemblies, and one buffer assembly is arranged above each link assembly. The buffer assembly includes:

[0021] The buffer assembly base is arranged above the fixed slide rail.

[0022] The telescopic plug rod is slidably arranged in the buffer assembly base, and the telescopic plug rod is inserted into the sliding track.

[0023] The compression spring damper is arranged in the buffer assembly base to provide damping when the telescopic plug rod retracts upward.

[0024] As a further implementation scheme:

[0025] The buffer assembly base includes a transverse base, a side base arranged below the left side of the transverse base, a plug rod slideway formed below the transverse base a, a gear side hole communicated and arranged on the side of the plug rod slideway, a damping longitudinal cavity formed in the side base, a nut side hole formed at the lower left end of the damping longitudinal cavity, and a longitudinal core shaft formed in the nut side hole.

[0026] The telescopic plug rod includes a guiding plug strip arranged in the plug rod slideway, a limiting end formed at the lower left end of the guiding plug strip, a plug rod body slidably inserted in the plug rod slideway, a guiding through hole formed on the right side of the plug rod body and in plug-in fit with the guiding plug strip, and a limiting blind groove formed on the side of the guiding through hole.

[0027] The compression spring damper includes a transmission gear rotatably arranged in the gear side hole, a through core shaft rotatably arranged in the damping longitudinal cavity, a driven rack slidably sleeved on the through core shaft and meshed with the transmission gear, an external thread part formed on the lower half part of the through core shaft, a driven nut screwed on the external thread part, a rotation stopping plug formed on the side of the driven nut, a rotation stopping side hole formed on the side of the damping longitudinal cavity and cooperating with the rotation stopping plug, a compression spring wound around the through core shaft between the driven rack and the driven nut, a driven gear formed at the lower end of the through core shaft, and a driving gear rotatably arranged on the longitudinal core shaft and meshed with the driven gear.

[0028] Benefiting from the above - improved technical features, the buffer assembly can provide damping in the first stage through the compression spring damping.

[0029] The buffer assembly further includes a leaf - spring damping. The leaf - spring damping includes a detachable cover detachably arranged at the upper end of the transverse base, and a plate - shaped compression spring formed at the lower end of the detachable cover and inserted into the upper end of the insertion rod slideway.

[0030] Benefiting from the above - improved technical features, the leaf - spring damping is used to provide damping in the second stage.

[0031] Furthermore, the stiffness coefficient of the plate - shaped compression spring is not less than ten times that of the compression spring, so as to ensure that the plate - shaped compression spring can generate a sufficiently large thrust within a smaller deformation range to meet the buffer requirements when the doors and windows are approaching the closed state.

[0032] Beneficial effects:

[0033] For the safety doors and windows described in this case, the opening method of pushing the lower end of the flipping window body outwards is realized through the connecting rod assembly, and the buffer assembly effectively realizes the... during window closing.

[0034] For the safety doors and windows described in this case, the buffer assembly of the safety doors and windows realizes the buffering and deceleration during the closing of the flipping window body through two - stage damping, which can not only reduce noise and mechanical damage, but also avoid damaging the items accidentally placed under the lower edge of the window frame assembly or the hands of the user:

[0035] First, the compression spring damping provides damping in the first stage. This damping can be linearly adjusted within a relatively long adjustment range because the insertion rod body can play a damping role throughout the process of being pushed by the hinge base, which can effectively prevent the flipping window body from closing quickly under the action of gravity, thus causing huge noise and mechanical loss; further, this damping can also be adjusted to adapt to safety doors and windows with different self - weights and different lubrication conditions.

[0036] Then, the leaf - spring damping is used to provide damping in the second stage. Furthermore, the stiffness coefficient of the plate - shaped compression spring is not less than ten times that of the compression spring, so as to ensure that the plate - shaped compression spring can generate a sufficiently large thrust within a smaller deformation range to meet the buffer requirements when the doors and windows are approaching the closed state.

[0066] A safety door and window, comprising:

[0067] Window frame assembly 1, fixed on the building foundation;

[0068] Link assembly 2, arranged on the window frame assembly 1;

[0069] Flip window 3, arranged on the link assembly 2, and the lower edge of the flip window 3 is set to flip forward;

[0070] Buffer assembly 4, arranged above the link assembly 2 to absorb the kinetic energy when the flip window 3 closes quickly.

[0071] As a further embodiment:

[0072] The window frame assembly 1 includes a rectangular frame 11 formed by connecting and molding in four directions: up, down, left, and right. A rectangular bottom frame 12 is formed inward in the plane on the rear end face of the rectangular frame 11. A rectangular sealing bottom frame 13 is provided at the front end of the rectangular bottom frame 12.

[0073] A pair of link assemblies 2 are provided. A link assembly 2 is provided on each of the left and right sides of the rectangular frame 11. The link assembly 2 includes:

[0074] A fixed slide rail 21 is fixedly provided on the left or right side of the rectangular frame 11. A sliding track 21a is provided on the inner wall of the fixed slide rail 21. An anti - detachment opening 21b with a narrowed width is provided on the side of the sliding track 21a.

[0075] A hinged base 22 is slidably provided in the fixed slide rail 21. An upper hinged arm 22a is hinged above the hinged base 22, and a hinged link 22b is hinged below the hinged base 22.

[0076] A lower hinged arm 23 is hinged on the left or right side of the rectangular frame 11.

[0077] The flipping window 3 at least includes a flipping frame 31 formed by connecting and molding in four directions: up, down, left, and right, and a rectangular glass 32 provided at the front end of the flipping frame 31. The side of the flipping frame 31 is hinged to the distal ends of the lower hinged arm 23 and the upper hinged arm 22a.

[0078] Thanks to the above - improved technical solution, when the flipping frame 31 of the flipping window 3 is closed, it can contact the sealing bottom frame 13 to achieve window sealing.

[0079] As a further embodiment:

[0080] A handle is provided on the lower side of the flipping frame 31.

[0081] A pair of buffer assemblies 4 are provided. A buffer assembly 4 is provided above each link assembly 2. The buffer assembly 4 includes:

[0082] A buffer assembly base 41 is provided above the fixed slide rail 21.

[0083] A telescopic insertion rod 42 is slidably provided in the buffer assembly base 41, and the telescopic insertion rod 42 is inserted into the sliding track 21a.

[0084] A compression spring damper 43 is provided in the buffer assembly base 41 to provide damping when the telescopic insertion rod 42 retracts upward.

[0085] As a further embodiment:

[0086] The buffer assembly base 41 includes a transverse base 41a, a side base 41b provided below the left side of the transverse base 41a, a plug rod slideway 41c formed below the transverse base 41a, a gear side hole 41d communicatively provided on the side of the plug rod slideway 41c, a damping longitudinal cavity 41e formed in the side base 41b, a nut side hole 41f formed at the lower left end of the damping longitudinal cavity 41e, and a longitudinal mandrel 41g formed in the nut side hole 41f;

[0087] The telescopic plug rod 42 includes a guiding insert 42a provided in the plug rod slideway 41c, a limiting end 42b formed at the lower left end of the guiding insert 42a, a plug rod body 42c slidably inserted in the plug rod slideway 41c, a guiding through hole 42d formed on the right side of the plug rod body 42c and inserted and matched with the guiding insert 42a, and a limiting blind groove 42e formed on the side of the guiding through hole 42d;

[0088] The compression spring damper 43 includes a driving gear 43a rotatably provided in the gear side hole 41d, a through mandrel 43b rotatably provided in the damping longitudinal cavity 41e, a driven rack 43c slidably sleeved on the through mandrel 43b and meshed with the driving gear 43a, an external thread portion 43d formed on the lower half of the through mandrel 43b, a driven nut 43e screwed on the external thread portion 43d, a rotation preventing plug 43f formed on the side of the driven nut 43e, a rotation preventing side hole 43g formed on the side of the damping longitudinal cavity 41e and matched with the rotation preventing plug 43f, a compression spring 43h wound around the through mandrel 43b between the driven rack 43c and the driven nut 43e, a driven gear 43i formed at the lower end of the through mandrel 43b, and a driving gear 43j rotatably provided on the longitudinal mandrel 41g and meshed with the driven gear 43i.

[0089] Thanks to the above improved technical features, the buffer assembly can provide damping in the first stage through the compression spring damper 43. This damping has the advantages of linearity and adjustability and can play a damping role throughout the whole process of the plug rod body 42c being pushed by the hinged base 22, avoiding the rapid closing of the flipping window 3 under the action of gravity and thus causing huge noise and mechanical losses.

[0090] The buffer assembly 4 further includes a leaf spring damper 44. The leaf spring damper 44 includes a detachable cover 44a detachably provided at the upper end of the transverse base 41a and a plate-shaped compression spring 44b formed at the lower end of the detachable cover 44a and inserted into the upper end of the plug rod slideway 41c.

[0091] Thanks to the above improved technical features, the leaf spring damper 44 is used to provide damping in the second stage.

[0092] Further, the stiffness coefficient of the plate-shaped compression spring 44b is not less than ten times that of the compression spring 43h, thereby ensuring that the plate-shaped compression spring 44b can generate a sufficiently large thrust within a smaller deformation range to meet the buffering requirements when the doors and windows are in a near-closed state.

[0093] Benefiting from the above improved technical features, the buffer assembly 4 is structurally compact and integrally in an "L" shape that folds downward, facilitating its installation at the upper end position of the rectangular frame 11 on the fixed slide rail 11. And the buffer assembly 4 is dimensionally compact in the left-right direction. Since the telescopic insertion rod 42 and the leaf spring damper 44 can be arranged as thin sheet structures in the left-right direction, the reduction of the left-right dimension of the buffer assembly 4 substantially depends on the compression spring damper 43. In this case, a two-stage gear structure of the driving gear 43j and the driven gear 43i is adopted, which can achieve a more compact structure compared with the scheme of directly using a single-stage gear coaxial with the through core shaft 43b. Because in order to be able to operate outside the side base 41b, the size of the single-stage gear structure inevitably needs to be enlarged to expose it outside the side base 41b.

[0094] Based on the above door and window structure, this case also provides a method for using a safety door and window, which is characterized in that:

[0095] It includes the following steps:

[0096] Step 1, outward opening:

[0097] Push the lower end of the flipping window 3;

[0098] The hinge base 22 moves downward along the fixed slide rail 21, and the distal ends of the hinge connecting rod 22b and the lower hinge arm 23 swing forward;

[0099] The distal end of the upper hinge arm 22a swings forward adaptively;

[0100] The swinging of the upper hinge arm 22a and the lower hinge arm 23 drives the flipping window 3 to open outward and move downward moderately;

[0101] Step 2, closing the window:

[0102] Pull the lower end of the flipping window 3 inward, and the connecting rod assembly 2 and the flipping window 3 move in the opposite direction to that in Step 1; until the hinge base 22 moves upward and triggers the buffer assembly 4

[0103] Step 3, buffering of the buffer assembly 4:

[0104] Step 3.1, first-stage damping:

[0105] The hinge base 22 pushes the insertion rod body 42c upward, and the insertion rod body 42c drives the transmission gear 43a to rotate;

[0106] The driving gear 43a drives the driven rack 43c to move downward against the damping of the compression spring 43h, generating the first-stage damping;

[0107] Step 3.2, second-stage damping:

[0108] When the plug body 42c continues to move upward and abuts against the plate-shaped compression spring 44b, the second-stage damping is generated.

[0109] As a further implementation:

[0110] It further includes Step 3.3, adjusting the first-stage damping:

[0111] Rotate the driving gear 43j to drive the driven gear 43i, the through core shaft 43b, and the external thread portion 43d to rotate, and drive the driven nut 43e and the anti-rotation plug 43f to move along the anti-rotation side hole 43g;

[0112] Adjust the position of the driven nut 43e, adjust the compression amount of the compression spring 43h, and further adjust the second-stage damping when the driven rack 43c moves.

[0113] It should be noted that the safety-type door and window further includes a limiter 5. There are two limiters 5, and one limiter 5 is respectively provided below each connecting rod assembly 2. The limiter 5 includes:

[0114] The limiter housing 51 includes a "U"-shaped housing 51a inserted at the lower end of the fixed slide rail 21. A sliding insertion track 51b is provided on the front side of the rear arm of the "U"-shaped housing 51a, and a toothed slide track 51c is provided on the rear side of the front arm of the "U"-shaped housing 51a;

[0115] The limiter stop 52 includes a limit inner block 52a slidably arranged in the sliding track 21a, a side connecting rod assembly 52b formed at the upper end of the limit inner block 52a and passing through the anti-detachment opening 21b, and a locking cross plate 52c formed at the upper end of the side connecting rod assembly 52b;

[0116] The adjusting device 53 includes a driving jack 53a arranged in the limit inner block 52a in the up-down direction, a middle connecting hole 53b formed on the left side of the driving jack 53a, a driving jack 53c formed in the locking cross plate 52c and communicating with the middle connecting hole 53b, an internal thread ring 53d slidably arranged in the driving jack 53a, a communicating plug rod 53e formed on the side surface of the internal thread ring 53d and inserted into the driving jack 53c through the middle connecting hole 53b, and an external threaded rod 53f screwed into the internal thread ring 54d. The upper rear end of the external threaded rod 53f is understood to be provided with an exposed torsion rod 53g passing through the limiter stop 52 through a pair of gear transmissions;

[0117] The plate-shaped lock cylinder 54 includes a lock cylinder substrate 54a slidably disposed in the driving insertion hole 53c, a locking tooth surface 54b formed on the side surface of the lock cylinder substrate 54a and engaged with the toothed slideway 51c, a driven inclined surface 54c formed below the lock cylinder substrate 54a and abutted against the communicating insertion rod 53e, a sliding core hole 54d formed in the lock cylinder substrate 54a, a sliding core shaft 54e disposed at the rear end of the driving insertion hole 53c and inserted into the sliding core hole 54d, and a return spring 54f formed in the sliding core hole 54d and abutted against the sliding core shaft 54e.

[0118] A reinforcing side block 51d is further provided on the front side of the "U"-shaped outer shell 51a, and the reinforcing side block 51d is fixedly connected to the rectangular frame 11.

[0119] Thanks to the above improved technical features, the structure of the limiter 5 is compact, and the size in the left-right direction can be minimized to make it only have the size thickness of the plate-shaped lock cylinder 54 in the left-right direction. The plate-shaped lock cylinder 54 can adopt a high-strength metal material to reduce the size on the premise of ensuring its structural strength. Finally, on the premise of realizing the limiting function, interference with the operation of the link assembly 2 can be avoided.

[0120] Thanks to the above improved technical features, the limiter 5 can adjust the maximum opening and closing angle of the flipping window 3. The method for adjusting the opening and closing angle of the door and window includes the following steps:

[0121] Step 1. Unlock the plate-shaped lock cylinder 54:

[0122] Rotate the exposed torsion rod 53g to drive the external threaded rod 53f to rotate;

[0123] The external threaded rod 53f drives the internal threaded ring 53d and the communicating insertion rod 53e to move downward;

[0124] The return spring 54f pulls the locking tooth surface 54b to move inward to disengage from the toothed slideway 51c and thus unlock;

[0125] Step 2. Adjust the angle:

[0126] Push the plate-shaped lock cylinder 54 to move it up and down along the limiter housing 51, adjust the limit distance of the hinge base 22 moving downward, and thus adjust the opening and closing angle of the flipping window 3;

[0127] Step 3. Fix the plate-shaped lock cylinder 54:

[0128] Rotate the exposed torsion rod 53g in the direction opposite to that in Step 1, thereby driving the external threaded rod 53f to rotate in the reverse direction, and finally realizing the upward movement of the internal threaded ring 53d and the communicating insertion rod 53e, driving the locking tooth surface 54b to move outward against the pulling force of the return spring 54f, and thus locking with the toothed slideway 51c.
