[0039] The specific embodiments are all taken as examples of side pressure sashes, such as Figures 1-3 As shown in the drawings, a side pressure buffering device includes a base 1, a buffering assembly, the base 1 is provided with a containing groove 11, the containing groove 11 extends along the left-right direction, the containing groove 11 can accommodate the buffering assembly, the buffering assembly is arranged in the containing groove 11, the left side of the containing groove 11 is fixedly connected with a first guide rod 111, the right side of the containing groove 11 is fixedly connected with a second guide rod 112, the first guide rod 111 and the second guide rod 112 both extend along the front-back direction, the first guide rod 111 is slidably connected with the left side of the buffering assembly, the second guide rod 112 is slidably connected with the right side of the buffering assembly, the front-back width W4 of the containing groove 11 is greater than the front-back width W3 of the buffering assembly, so that the base 1 can slide relative to the buffering assembly along the front-back direction.

[0040] The buffering assembly can provide buffering effect for the left-right movement of the side pressure sash 3, the buffering assembly is slidably connected with the base 1, so that the base 1 can move along the front-back direction, the flexibility of the side pressure buffering device is improved, and the buffering assembly is suitable for application in the side pressure window.

[0041] The base 1 is composed of a rectangular bottom plate and two rectangular vertical plates on the front and back. The inner side of the rectangular bottom plate and the inner side of the two rectangular vertical plates form a containing groove 11. The first guide rod 111 and the second guide rod 112 are fixedly connected between the two rectangular vertical plates. The buffer assembly is slidably connected with the first guide rod 111 and the second guide rod 112, respectively. The front-to-back width W4 of the containing groove 11 is greater than the front-to-back width W3 of the buffer assembly, so that a sliding space is left between the buffer assembly and the two rectangular vertical plates. A certain space is left between the buffer assembly and the rectangular bottom plate below, preventing friction and collision between the base 1 and the buffer assembly when the base 1 slides forward and backward. A plurality of fixing holes are provided on the front and back of the rectangular bottom plate, and the base 1 can be fixedly connected with the side pressure sash 3 by using screws.

[0042] In some embodiments, the left side of the buffer assembly is provided with a first pulley 21, and the right side of the buffer assembly is provided with a second pulley 22. The first pulley 21 and the second pulley 22 are both horizontally placed and can roll in the horizontal direction. The diameters of the first pulley 21 and the second pulley 22 are equal, and the diameters are greater than the front-to-back width W3 of the buffer assembly.

[0043] The first pulley 21 and the second pulley 22 abut against the outer frame track 4. During the left-right movement of the side pressure sash 3, the first pulley 21 and the second pulley 22 can roll inside the outer frame track 4 above the side pressure sash 3. The diameters of the first pulley 21 and the second pulley 22 are wider than the front-to-back width W3 of the buffer assembly, avoiding contact between the buffer assembly and the outer frame track 4, preventing the base 23 of the buffer assembly from colliding with and rubbing against the outer frame track 4, and preventing noise and damage to parts.

[0044] Further, a guide seat 211 is fixedly connected to the left side and the right side of the buffer assembly, respectively. Each of the two guide seats 211 has a through hole, and the two guide seats 211 are respectively worn on the first guide rod 111 and the second guide rod 112, so that the buffer assembly can slide forward and backward. The first pulley 21 and the second pulley 22 are respectively installed on the guide seats 211 on both sides of the buffer assembly. The guide seats 211 play a role in supporting the first pulley 21 and the second pulley 22 and guiding left and right. The first pulley 21 and the second pulley 22 can be installed on the guide seats 211 by using screws, rivets, pins, etc.

[0045] Further, the materials of the first pulley 21 and the second pulley 22 can be selected from plastics such as nylon and polyethylene, and composite materials such as carbon fiber reinforced plastic and TPU, so that the first pulley 21 and the second pulley 22 make less noise when rolling in the outer frame track 4, and when the side pressure sash 3 moves forward and backward, the materials of the first pulley 21 and the second pulley 22 have a certain elasticity, which can absorb a certain amount of forward and backward extrusion force.

[0046] In some embodiments, the first pulley 21 and the second pulley 22 are located outside the containing groove 11 in the vertical direction.

[0047] The outer frame track 4 has a certain spacing with the side pressure sash 3 to avoid the impact between the base 1 and the outer frame track 4, and the first pulley 21 and the second pulley 22 are higher than the accommodating groove 11 in the vertical direction, so that the first pulley 21 and the second pulley 22 can move inside the outer frame track 4.

[0048] In some embodiments, the base 1 is provided with an avoiding hole 13 below.

[0049] The avoiding hole 13 below the base 1 can avoid the parts on the side pressure sash 3 when the side pressure buffering device is installed on the side pressure sash 3.

[0050] The rectangular avoiding hole 13 is provided in the middle of the rectangular bottom plate on the base 1, and the avoiding hole 13 extends in the left-right direction to leave a certain gap between the side pressure buffering device and the side pressure sash 3.

[0051] In some embodiments, the buffering assembly includes a base 23, an elastic arm, two push blocks 25, a buffering pipe 26, and a clamping hole 27. The base 23 is provided with a groove 231 extending in the left-right direction, and the buffering pipe 26 is arranged in the groove 231. The left side and the right side of the buffering pipe 26 are respectively in transmission connection with the two push blocks 25. The elastic arm is arranged between the two push blocks 25 and is in transmission connection with the two push blocks 25. The clamping hole 27 is arranged on the left and right sides of the base 23, and the two push blocks 25 can be clamped with the clamping hole 27.

[0052] The buffering pipe 26 can play a buffering role. The two push blocks 25 are in transmission connection with the left side and the right side of the buffering pipe 26, so that the buffering assembly has a double-side buffering effect. After the elastic arm is stretched, the elastic arm pulls the side pressure sash under the action of elastic contraction to avoid the phenomenon that the side pressure sash 3 cannot be tightly closed. The clamping hole 27 can clamp the push block 25 to prevent the elastic arm from automatically contracting and pulling back the push block 25.

[0053] A side pressure sash 3 includes a side pressure buffering device, an outer frame track 4, and the side pressure sash 3. The outer frame track 4 is provided with a limiting device, and the outer frame track 4 is fixedly connected with the limiting device. The side pressure sash 3 is fixedly connected with the side pressure buffering device. When the side pressure sash 3 moves left and right, the limiting device can cooperate with the buffering assembly to control the buffering of the side pressure sash 3.

[0054] The cooperation of the limiting device and the buffering assembly can buffer the movement of the side pressure sash 3 left and right to prevent violent impact on the outer frame. The base 1 can slide synchronously when the door and window or the sash moves forward and backward, which facilitates the smoother forward and backward movement of the side pressure sash 3.

[0055] The side pressure buffering device is fixedly connected on the side pressure sash 3 through the fixing hole on the base 1 and the connecting hole on the top of the side pressure sash 3. The limiting device is provided with a mounting hole, and the outer frame track is provided with a mounting hole. The limiting device is fixed in the outer frame track 4 by using the mounting hole in the outer frame track 4 and the mounting hole on the limiting device. The limiting device can control the buffering of the side pressure sash 3 in cooperation with the side pressure buffering device. The outer frame track 4 on the left side and the right side of the side pressure buffering device is fixedly connected with two limiting devices. The limiting device is rectangular. Each of the left side and the right side of the limiting device is provided with a limiting foot 421. The limiting foot 421 can be clamped on the driving block 25 when the side pressure buffering device moves left and right.

[0056] Taking the right driving block 25 of the side pressure buffering device as an example, when the side pressure sash 3 is pushed to the left side, the limiting device on the right side of the outer frame track 4 clamps the right driving block 25, so that the position of the driving block 25 is fixed. The buffering pipe 26 moves relative to the left side of the right limiting device. The buffering rod in the buffering pipe 26 starts to lengthen until the buffering preparation is completed. Then the side pressure sash 3 is pushed to the right side. The side pressure buffering device moves to the right side. The right limiting device clamps the right driving block 25 again to prevent the driving block 25 from moving to the right side. The buffering pipe 26 approaches the right driving block 25. The buffering rod starts to shorten. At this time, the buffering pipe 26 generates resistance to slow down the movement of the side pressure sash 3 to the right side. The left side is the same. The left side and the right side of the buffering pipe 26 are cyclically buffered to complete the left and right buffering functions of the side pressure sash 3.

[0057] When the side pressure sash 3 is subjected to side pressure, the side pressure sash 3 moves forward. Because the first pulley 21 and the second pulley 22 abut against the outer frame track 4 to limit the forward and backward movement of the buffering assembly, the base 1 can slide forward with the side pressure sash 3 to prevent the side pressure buffering device from affecting the forward and backward movement of the side pressure sash 3.

[0058] In some specific embodiments, the outer frame track 4 extends along the left-right direction. The outer frame track 4 is provided with a track groove extending along the front-rear direction. The lower side of the track groove is provided with an opening extending along the left-right direction. The limiting device includes a limiting block 42 and a track piece 411. The track piece 411 is clamped in the track groove. The track piece 411 is fixedly connected with the outer frame track 4. The limiting block 42 is fixedly connected below the track piece 411. The lower side of the limiting block 42 is provided with a limiting foot 421 extending downward. The limiting foot 421 can control the buffering of the side pressure movable sash in cooperation with the buffering assembly.

[0059] After the limiting block 42 is fixedly connected on the track piece 411, the track piece 411 can be slid into the outer frame track 4 through the track groove, so that the limiting block 42 is conveniently installed in the outer frame track 4.

[0060] The track piece 411 is rectangular, and a plurality of fixed through holes are arranged on the surface of the track piece 411 and connected with the mounting port on the limiting block 42, so that the limiting block 42 is fixedly connected to the track piece 411. Then, the track piece 411 is pushed into and fixed in the outer frame track 4. The front-to-back width W5 of the track piece 411 is adapted to the front-to-back width W6 of the track groove. The track piece 411 can be clamped in the track groove, so as to adjust the distance between the limiting block 42 and the side pressure buffering device, and facilitate the limiting block 42 to clamp the driving block 25.

[0061] In some specific embodiments, the outer frame track 4 extends along the left-right direction, and the outer frame track 4 is provided with a track groove extending along the front-to-back direction. The lower side of the track groove is provided with an opening. The front-to-back width of the track groove is W6, and the front-to-back width of the opening is W2. The limiting device comprises a rear-mounted limiting block. The rear-mounted limiting block is detachably connected to the track groove. The lower side of the rear-mounted limiting block 5 is provided with a trigger foot 51 extending downward. The trigger foot 51 can cooperate with the buffering assembly to control the buffering side-hung sash 3. The rear-mounted limiting block 5 has a first width L1 and a second width L2. The first width L1 is greater than the second width L2. The second width L2 is less than or equal to W2. The first width L1 is greater than W2 and less than or equal to W6. When the rear-mounted limiting block 5 is installed, the rear-mounted limiting block 5 can be rotated to the direction of the second width L2 parallel to the front-to-back direction and pass through the opening into the track groove. Then, the rear-mounted limiting block 5 is rotated to the first width L1 parallel to the front-to-back direction and clamped in the track groove.

[0062] The conventional limiting block 42 needs to be clamped in the track groove. The width between the front side and the rear side of the limiting block 42 is W1, where W1 is greater than W2. Therefore, the limiting block 42 can only be installed from the left and right sides of the outer frame track and needs to be installed together with the side-hung sash 3. The rear-mounted limiting block 5 can be installed after the side-hung door and window are installed. The rear-mounted limiting block 5 is rotated to the direction of the second width L2 parallel to the front-to-back direction and passes through the opening into the track groove. When the rear-mounted limiting block 5 reaches the height of the track groove, the rear-mounted limiting block 5 is rotated again to the first width L1 parallel to the front-to-back direction, so that the rear-mounted limiting block 5 is clamped in the track groove. Then, the rear-mounted limiting block 5 is fixed in the outer frame track 4.

[0063] Further, as shown in FIG. 6, the outer frame track 4 is provided with a track groove 41 extending along the front-to-back direction. The lower side of the track groove 41 is provided with an opening 42. The front-to-back width of the track groove 41 is W6, and the front-to-back width of the opening 42 is W2. The limiting device comprises a rear-mounted limiting block 5. The rear-mounted limiting block 5 is detachably connected to the track groove 41. The lower side of the rear-mounted limiting block 5 is provided with a trigger foot 51 extending downward. The trigger foot 51 can cooperate with the buffering assembly to control the buffering side-hung sash 3. The rear-mounted limiting block 5 has a first width L1 and a second width L2. The first width L1 is greater than the second width L2. The second width L2 is less than or equal to W2. The first width L1 is greater than W2 and less than or equal to W6. When the rear-mounted limiting block 5 is installed, the rear-mounted limiting block 5 can be rotated to the direction of the second width L2 parallel to the front-to-back direction and pass through the opening 42 into the track groove 41. Then, the rear-mounted limiting block 5 is rotated to the first width L1 parallel to the front-to-back direction and clamped in the track groove 41. Figures 4-8As shown, the front and rear width of the rear-mounted limiting block is L1. The rear-mounted limiting block 5 is placed so that the direction of L1 is parallel to the direction of W2. Then, the rear-mounted limiting block 5 is rotated horizontally by 45°. At this time, the width of the rear-mounted limiting block 5 parallel to the direction of W2 reaches the second width L2, where L2 = W2. The rear-mounted limiting block 5 can enter the track groove from the opening of the outer frame track 4. Then, it is rotated horizontally in the opposite direction by 45°. At this time, the width of the rear-mounted limiting block 5 parallel to the direction of W6 reaches the first width L1, where L1 = W6. The rear-mounted limiting block 5 is snapped into the track groove and fixedly installed in the outer frame track 4. When the side pressure buffer device moves left and right, the rear-mounted limiting block 5 can lock the actuating block 25. With the side-pressure window sashes already installed, the rear-mounted limiting block 5 can be installed on the side-pressure window sashes without removing the outer frame track 4. The trigger foot 51 is vertically set on the lower side of the rear-mounted limiting block 5. There are two trigger feet 51 on the front and rear sides of the rear-mounted limiting block 5, which facilitates the back-and-forth movement of the toggle block 25 on the buffer assembly.

[0064] In some specific embodiments, the left and right sides of the rear mounting limiting block 5 are each provided with a slanted chamfer, and the left and right sides of the rear mounting limiting block 5 are also provided with a rounded chamfer. The two slanted chamfers are located on the side away from the trigger foot 51, and the two rounded chamfers are located on the side close to the trigger foot 51. When the rear mounting limiting block 5 rotates horizontally, the rounded chamfers can abut against the inner side of the outer frame track 4.

[0065] The chamfered and rounded chamfers can reduce the friction between the rear-mounted limiting block 5 and the outer frame track 4 when the rear-mounted limiting block 5 slides upward and rotates horizontally, thus preventing damage to the rear-mounted limiting block 5.

[0066] See attached for details. Figure 6 For example, the top surface of the rear-mounted limiting block 5 is Z-shaped, the trigger foot 51 is located below the rear-mounted limiting block 5, and two beveled corners are located at the top and bottom of the Z-shape away from the trigger foot 51. The beveled surfaces are parallel and the angle is 45°. The top of the two beveled corners is also rounded. The rounded corners can prevent the top and bottom of the Z-shape of the rear-mounted limiting block 5 from being too sharp and causing injury to the hands during installation. The beveled corners not only reduce the contact area between the rear-mounted limiting block 5 and the outer frame track 4, thus reducing friction, but also serve as a guide for installation. The two rounded corners are located in the middle section of the Z-shape of the rear-mounted limiting block 5 near the trigger foot 51, so that when the rear-mounted limiting block 5 rotates inside the outer frame track 4, the part of the rounded corner that abuts can roll, thus reducing friction and facilitating the installation of the rear-mounted limiting block 5. The rear-mounted limiting block 5 is also provided with a circular through hole for fixing to the outer frame track 4.
