Description

Technical Field

[0001] This utility model relates to the field of sliding window technology, and in particular to a building sliding window. Background Technology

[0002] Currently, with the continuous improvement of building energy efficiency standards, energy-saving renovation of existing building windows has become a key aspect of reducing building energy consumption. As an important component of the building envelope, building windows not only need to meet thermal insulation requirements but also need to consider multiple functions such as lighting, ventilation, decoration, sound insulation, and fire resistance. At present, the renovation of existing building windows mainly adopts two methods: complete window replacement and partial renovation. While sliding windows are still widely used in low-rise residential buildings, villas, shops, and office buildings due to their simple structure and economical cost, their shortcomings, such as insufficient sealing performance, short service life, and poor structural stability, are particularly prominent.

[0003] From a sealing perspective, sliding windows mostly use weatherstripping for sealing. The gap between the sliding sash and the fixed frame easily forms a significant air convection channel, causing outdoor air to frequently enter and exit the room through the gap, directly weakening the overall airtightness. It is worth noting that as the service life increases, the sealing materials of sliding windows, such as weatherstripping, will gradually age and wear down, with their elasticity and sealing performance continuously declining, further exacerbating the deterioration of airtightness.

[0004] Sliding windows with insufficient airtightness can cause frequent exchanges of indoor and outdoor air, leading to greater fluctuations in indoor temperature: in winter, cold air can enter through the gaps, causing the room temperature to drop and making people feel cold; in summer, hot air can enter the room carrying dust and noise, which not only affects the comfort of living, but also forces temperature control equipment such as air conditioners and heaters to run at high frequency to maintain the room temperature, significantly increasing energy consumption. Utility Model Content

[0005] This utility model provides a building sliding window to solve the problems of poor thermal insulation performance and low indoor environmental comfort caused by poor air tightness, easy aging and wear of sealing strips in related technologies.

[0006] This utility model provides a sliding window for buildings, including:

[0007] Fixed frame,

[0008] A push-pull fan assembly has a closed state and an open state. The push-pull fan assembly includes a push-pull fan body, which is movably disposed on the fixed frame.

[0009] A first sealing structure is provided between the push-pull fan body and the fixed frame to seal the gap between them in the horizontal direction;

[0010] The first sealing structure includes a first sealing pad and a second sealing pad. The first sealing pad is located at the horizontal position of the fixed frame, and the second sealing pad is located at the corresponding horizontal position of the push-pull fan body. The first sealing pad and the second sealing pad are arranged facing each other and have a preset gap. The first sealing pad and the second sealing pad are respectively provided with a first sealing strip for sealing contact between the two.

[0011] When the push-pull fan assembly is in the closed state, the first sealing pad and the first sealing strip corresponding to each of the second sealing pads abut against each other, and the contact surface formed by the two is arranged at an inclined angle with the moving direction of the push-pull fan assembly.

[0012] According to the present invention, a sliding window for building is provided, wherein the first sealing gasket is provided with a first inclined surface, and the second sealing gasket is provided with a second inclined surface toward the first sealing gasket, and the first inclined surface and the second inclined surface are adapted to each other and can abut against each other.

[0013] The first sealing strip on the first sealing gasket is arranged along the first inclined surface, and the first sealing strip on the second sealing gasket is arranged along the second inclined surface.

[0014] According to the present invention, a sliding window for building is provided, wherein the first sealing gasket has a first side and a second side opposite to each other along the vertical direction of the fixed frame, the first side being close to the sliding sash body and the second side being away from the sliding sash body;

[0015] The first inclined surface is formed on the first side of the first sealing gasket, and the distance between the first inclined surface and the second side gradually decreases along the moving direction of the push-pull fan body when the push-pull fan assembly is in the open state.

[0016] According to the present invention, a building sliding window is provided, wherein the first sealing gasket is provided with a first mounting groove located on the first inclined surface, and the second sealing gasket is provided with a second mounting groove located on the second inclined surface.

[0017] Both the first assembly groove and the second assembly groove are embedded and fixed to their respective first sealing strips.

[0018] According to the present invention, a sliding window for building is provided, wherein the fixed frame is provided with a slide rail groove, and the sliding sash body is provided with a slide rail part located in the slide rail groove;

[0019] The first sealing gasket is disposed in the slide rail groove, and the second sealing gasket is disposed on one side of the slide rail portion facing the bottom wall of the slide rail groove.

[0020] According to the present invention, a sliding window for building is provided, wherein the first sealing structure is provided between the upper side of the fixed frame and the upper side of the sliding sash, and between the lower side of the fixed frame and the lower side of the sliding sash.

[0021] According to the present utility model, there are two sliding sashes, which are movably disposed on the fixed frame.

[0022] A second sealing structure for sealing the gap between two adjacent push-pull fan bodies is provided. The second sealing structure includes two second sealing strips arranged in opposite directions, and the two second sealing strips are connected to the two push-pull fan bodies one by one.

[0023] When the push-pull fan assembly is in the closed state, the two second sealing strips abut against each other, and the contact surface formed by the two is arranged at an inclined angle to the moving direction of the push-pull fan assembly.

[0024] According to the present invention, in a building sliding window, the sidewall portions of two adjacent sliding sashes in the thickness direction overlap, and two second sealing strips are located between the overlapping areas of the two adjacent sliding sashes.

[0025] According to the present invention, a sliding window for building is provided, wherein both second sealing strips are provided with a third inclined surface, and the distance between the third inclined surface and the side wall of the sliding sash gradually increases along the moving direction of the sliding sash when the sliding sash assembly is in the open state.

[0026] According to the present invention, a sliding window for building is provided, wherein each of the sliding sashes and the fixed frame is provided with a third sealing structure for sealing the vertical gap between the two.

[0027] The third sealing structure includes a first vertical sealing strip and a second vertical sealing strip. The first vertical sealing strip is located at the vertical position of the fixed frame, and the second vertical sealing strip is located at the corresponding vertical position of the push-pull fan body, and the two are arranged facing each other.

[0028] The sliding window provided by this utility model adopts a first sealing gasket and a second sealing gasket arranged facing each other, and is equipped with a sealing strip to form a double sealing barrier. Compared with a single weatherstrip seal, it significantly reduces the horizontal gap and structurally reduces the channel area for air convection. In the closed state, the contact surface of the two sealing strips is inclined at an angle to the moving direction of the sliding sash, which allows the sealing strip to generate elastic deformation compensation along the moving direction when under pressure. This not only ensures the reliability of the sealing contact at the moment of closure, but also delays the decay of sealing performance caused by sliding friction and material aging during long-term use.

[0029] By improving the airtightness of sliding windows without increasing their sliding force, the high-frequency exchange of indoor and outdoor air through horizontal gaps is effectively blocked, reducing indoor temperature fluctuations caused by poor airtightness. This reduces the energy consumption of air conditioning / heating and simultaneously improves indoor comfort in winter and summer. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0041] The following is combined Figures 1-6 The present invention describes a building sliding window, which includes a fixed frame 100 and a sliding sash assembly 200.

[0042] Reference Figure 1 , Figures 3 to 4 The push-pull fan assembly 200 has a closed state and an open state. The push-pull fan assembly 200 includes a push-pull fan body 210, which is movably disposed on the fixed frame 100.

[0043] Reference Figures 2 to 4 A first sealing structure 300 is provided between the push-pull fan body 210 and the fixed frame 100 to seal the gap between them in the horizontal direction; the first sealing structure 300 includes a first sealing pad 310 and a second sealing pad 320. The first sealing pad 310 is located in the horizontal direction of the fixed frame 100, and the second sealing pad 320 is located in the horizontal direction of the push-pull fan body 210. The first sealing pad 310 and the second sealing pad 320 are arranged facing each other and have a preset gap. The first sealing pad 310 and the second sealing pad 320 are respectively provided with a first sealing strip 330 for sealing contact between them.

[0044] When the push-pull fan assembly 200 is in the closed state, the first sealing pad 310 and the corresponding first sealing strip 330 on the second sealing pad 320 abut against each other, and the contact surface formed by the two is arranged at an inclined angle to the moving direction of the push-pull fan assembly 200.

[0045] The building sliding window provided by this utility model adopts a first sealing pad 310 and a second sealing pad 320 facing each other and is equipped with a sealing strip to form a double sealing barrier. Compared with a single weatherstrip seal, it significantly reduces the horizontal gap and structurally reduces the channel area for air convection. In the closed state, the contact surface of the two sealing strips is inclined at an angle to the moving direction of the sliding sash, which allows the sealing strip to generate elastic deformation compensation along the moving direction when under pressure. This not only ensures the reliability of the sealing contact at the moment of closure, but also delays the decay of sealing performance caused by sliding friction and material aging during long-term use.

[0046] By improving the airtightness of sliding windows without increasing their sliding force, the high-frequency exchange of indoor and outdoor air through horizontal gaps is effectively blocked, reducing indoor temperature fluctuations caused by poor airtightness. This reduces the energy consumption of air conditioning / heating and simultaneously improves indoor comfort in winter and summer.

[0047] Understandably, referring to Figures 2 to 4 In some examples of this utility model, the first sealing gasket 310 is provided with a first inclined surface 311, and the second sealing gasket 320 is provided with a second inclined surface 321 in the direction of the first sealing gasket 310. The first inclined surface 311 and the second inclined surface 321 are adapted to each other and can abut against each other.

[0048] The first sealing strip 330 on the first sealing gasket 310 is arranged along the first inclined surface 311, and the first sealing strip 330 on the second sealing gasket 320 is arranged along the second inclined surface 321.

[0049] With the above structure, the first inclined surface 311 and the second inclined surface 321 make both the first sealing gasket 310 and the second sealing gasket 320 wedge-shaped structures. The fitting and contacting of the first inclined surface 311 and the second inclined surface 321 form a gradual contact guide, so that the first sealing gasket 310 and the second sealing gasket 320 can smoothly fit along the first inclined surface 311 and the second inclined surface 321 when closed, avoiding local gaps caused by rigid collisions. Secondly, the first sealing strip 330 is set along the inclined surface, which can extend evenly along the inclined surface when under pressure, forming a continuous and tight contact interface, greatly increasing the sealing area and reducing air infiltration channels. In addition, the inclined surface structure can disperse the contact stress when closed, so that the first sealing strip 330 can maintain a more stable elastic deformation compensation ability during long-term push-pull friction or aging, delaying the decay of sealing performance caused by wear, and ultimately achieving a more reliable improvement in air tightness, effectively blocking indoor and outdoor air convection, reducing energy consumption and improving indoor comfort.

[0050] Of course, in other examples, the opposing sides of the first sealing pad 310 and the second sealing pad 320 can be designed as arcs, such as concave or convex arcs, and the corresponding first sealing strip 330 can be installed on the arc surface. When closed, the first sealing strip 330 of the first sealing pad 310 and the second sealing pad 320 can be guided to fit precisely through the gradual transition of the arc.

[0051] Understandably, referring to Figure 1 In some examples of this utility model, a first sealing structure 300 is provided between the upper side of the fixed frame 100 and the upper side of the push-pull fan body 210, and between the lower side of the fixed frame 100 and the lower side of the push-pull fan body 210.

[0052] The horizontal gaps on the upper and lower sides of the fixed frame 100 and the sliding fan body 210 are the main paths for air infiltration. The double-sided sealing structure forms a double barrier, which completely blocks the horizontal airflow exchange and avoids the risk of air leakage caused by the failure of a single seal.

[0053] The linkage between the upper and lower sealing structures can form a closed sealing path. Even if a small gap appears on one side due to aging, the other side can still compensate for the seal through elastic deformation, ensuring the complete closure of the horizontal gap in the closed state. This significantly reduces indoor and outdoor air convection, ultimately achieving a more stable and reliable improvement in air tightness, effectively reducing air conditioning / heating energy consumption and improving indoor environmental stability.

[0054] Setting the first sealing structure 300 in both of the above locations helps to cover all possible horizontal gaps, avoid omissions, and thus completely block air infiltration.

[0055] It should be noted that, referring to Figure 2 In some examples of this utility model, the fixed frame 100 is provided with a slide rail groove 110, and the push-pull fan body 210 is provided with a slide rail part 211 located in the slide rail groove 110;

[0056] The first sealing gasket 310 is disposed in the slide rail groove 110, and the second sealing gasket 320 is disposed on one side of the slide rail part 211 facing the bottom wall of the slide rail groove 110.

[0057] It can be understood that both the first sealing gasket 310 and the second sealing gasket 320 are located in the slide rail groove 110. The slide rail groove 110 protects the first sealing strip 330 from prolonged exposure to sunlight, delays aging, extends its service life, and also plays a certain positioning role.

[0058] More specifically, in some examples of this utility model, the upper and lower sides of the fixed frame 100 are provided with slide rail grooves 110, and the upper and lower sides of the push-pull fan body 210 are provided with slide rail portions 211. The first sealing gasket 310 can be fixed to the slide rail groove 110 by means of adhesive bonding, screwing, etc., and the second sealing gasket 320 can be fixed to the push-pull fan body 210 by means of adhesive bonding, screwing, etc. It can be understood that the lengths of both the first sealing gasket 310 and the second sealing gasket 320 are equal to the length of the push-pull fan body 210.

[0059] During installation, since the first sealing gasket 310 and the second sealing gasket 320 maintain a preset gap, the first sealing strip 330 is completely filled and installed in the preset gap, forming a certain compression effect and creating a horizontal seal.

[0060] Understandably, referring to Figures 2 to 4In some examples of this utility model, the first sealing pad 310 has a first side and a second side opposite to each other along the vertical direction of the fixing frame 100, the first side being close to the push-pull fan body 210 and the second side being away from the push-pull fan body 210.

[0061] The first inclined surface 311 is formed on the first side of the first sealing gasket 310, and the distance between the first inclined surface 311 and the second side gradually decreases along the moving direction of the push-pull fan body 210 when the push-pull fan assembly 200 is in the open state.

[0062] This can be understood as follows: the structural design of the distance between the first inclined surface 311 and the second side decreasing along the opening direction of the push-pull fan body 210 effectively avoids the risk of obstruction when the push-pull fan body 210 is opened and moved. Specifically, before the fan body is fully closed, as the push-pull fan body 210 moves, the compression of the first sealing strip 330 corresponding to the first sealing pad 310 and the second sealing pad 320 gradually adapts to the optimal state during the movement process. This progressive compression adaptation mechanism not only ensures the final sealing reliability, but also avoids hard collisions caused by excessive local compression during the closing process through the avoidance cooperation of "adapting while moving", thus taking into account both smooth movement and sealing effectiveness.

[0063] In some examples of this utility model, the first sealing gasket 310 is provided with a first mounting groove on the first inclined surface 311, and the second sealing gasket 320 is provided with a second mounting groove on the second inclined surface 321; both the first mounting groove and the second mounting groove are embedded and fixed with their respective first sealing strips 330.

[0064] The fitting design of the first mounting groove, the second mounting groove and the first sealing strip 330 makes the strip "locked" in the groove, effectively preventing the strip from loosening or falling off due to pushing and pulling friction, vibration or aging, ensuring that the first sealing strip 330 always stays in the correct position and avoiding gaps caused by strip displacement.

[0065] Furthermore, the fitting structure between the first and second mounting grooves and the first sealing strip 330 ensures a tighter fit between the sealing strip and the inclined surface. Under pressure, the sealing strip can extend evenly along the inclined surface, filling the tiny gaps at the contact interface and preventing localized sealing failure due to strip misalignment. This allows for precise control of the installation position and height of the first sealing strip 330, reducing the risk of misalignment between the two first sealing strips 330 during closure and ensuring the continuity and integrity of the contact interface. The grooves' wrapping protection of the strip reduces the erosion of the strip by external environmental factors (such as dust and moisture), slows down the aging rate, extends the service life of the sealing strip, maintains long-term stable sealing performance, and ultimately achieves the dual goals of improved airtightness and reduced energy consumption.

[0066] Of course, in other examples, the first sealing strip 330 and the first sealing pad 310, and the second sealing strip 410 and the second sealing pad 320 can be directly fixed by adhesive bonding; in addition, the interlocking structure and adhesive bonding process can be combined for assembly - that is, the installation accuracy of the strip is ensured by interlocking positioning, and the connection stability is enhanced by adhesive bonding, thereby achieving efficient and reliable fixing of the first sealing strip 330.

[0067] Understandably, referring to Figure 1 , Figure 2 , Figure 5 and Figure 6 In some examples of this utility model, there are two push-pull fan bodies 210, and the two push-pull fan bodies 210 are movably disposed on the fixed frame 100;

[0068] Reference Figure 2 , Figure 5 and Figure 6 A second sealing structure 400 for sealing the gap between two adjacent push-pull fan bodies 210 is provided. The second sealing structure 400 includes two second sealing strips 410 arranged in opposite directions, and the two second sealing strips 410 are connected to the two push-pull fan bodies 210 in a one-to-one correspondence.

[0069] When the push-pull fan assembly 200 is in the closed state, the two second sealing strips 410 abut against each other, and the contact surface formed by the two is arranged at an inclined angle to the moving direction of the push-pull fan assembly 200.

[0070] With the above configuration, the two opposing second sealing strips 410 form a double-sided abutment sealing mode when closed, which greatly increases the sealing coverage area of ​​the gap and effectively blocks the main path of air infiltration between the two push-pull fan bodies 210.

[0071] Secondly, the characteristic that the contact surface formed by the second sealing strip 410 abutting each other forms an inclined angle with the direction of push and pull movement allows the second sealing strip 410 to undergo elastic deformation along the inclined direction when under pressure. This ensures a tight fit at the moment of closure and can also compensate for the gap caused by slight misalignment of the fan body or aging of the second sealing strip 410 during long-term push and pull, thus delaying the decay of sealing performance.

[0072] In addition, the independent connection structure of the two rubber strips can be adapted to the movement trajectory of the corresponding push-pull fan body 210, reducing frictional resistance during push-pull and avoiding the risk of the rubber strip falling off or breaking due to uneven force on one side.

[0073] Specifically, refer to Figure 5 and Figure 6 In some examples of this utility model, the sidewall portions in the thickness direction of two adjacent push-pull fan bodies 210 overlap. This can be understood as the thickness direction of the two push-pull fan bodies 210 being the front-to-back direction.

[0074] The overlapping of the sidewalls along the thickness direction of the 210mm sliding fan body forms a natural "shielding barrier," reducing the free gaps exposed laterally between the fan bodies and structurally minimizing the potential path for air infiltration.

[0075] In some examples of this utility model, two second sealing strips 410 are located between the overlapping areas of two adjacent push-pull fan bodies 210.

[0076] With the above configuration, the second sealing strip 410 is located between the overlapping areas. By utilizing the physical limiting effect of the overlapping areas, the second sealing strip 410 can be effectively prevented from shifting or falling off due to misalignment of the push-pull fan body 210, vibration, or external impact, ensuring that the second sealing strip 410 is always stably attached to the fan body contact surface.

[0077] Furthermore, the synchronous movement characteristic of the overlapping area (the relative position of the overlapping part is fixed when the two push-pull fan bodies 210 move) makes the second sealing strip 410 more evenly compressed, reducing the risk of strip fatigue or breakage caused by excessive force on one side, and extending the service life of the sealing components; it also improves the sealing reliability when the double push-pull fan bodies 210 are closed, effectively blocks lateral air convection, reduces indoor and outdoor heat exchange, reduces air conditioning / heating energy consumption, and improves indoor environmental stability.

[0078] More specifically, refer to Figure 5 and Figure 6 In some examples of this utility model, both second sealing strips 410 are provided with a third inclined surface 411. The distance between the third inclined surface 411 and the side wall of the push-pull fan body 210 gradually increases along the moving direction of the push-pull fan body 210 when the push-pull fan assembly 200 is in the open state.

[0079] Through the above structure, the setting of the third inclined surface 411 makes the second sealing strip 410 a wedge-shaped structure. The distance between the third inclined surface 411 and the side wall of the push-pull fan body 210 gradually increases along the moving direction when the push-pull fan assembly 200 is opened. The above-mentioned adaptive gradual structure can effectively avoid obstructing the push-pull operation. When the push-pull fan assembly 200 is closed, the third inclined surface 411 of the two second sealing strips 410 forms a limiting constraint by precisely abutting, thereby tightly fitting the gap between the two fan bodies, increasing the sealing area, and increasing the sealing performance. It also forms a sealed closure with the first sealing strip 330 in the horizontal direction, achieving a reliable sealing effect.

[0080] It should be noted that, referring to Figure 1 , Figure 5 and Figure 6In some examples of this utility model, along the horizontal direction of the push-pull fan assembly 200, two push-pull fan bodies 210 are arranged left and right with some overlapping sidewalls. To achieve smooth relative sliding between the two, a sliding recess is provided at the bottom of the push-pull fan body 210, and a sliding protrusion adapted to the sliding recess is provided at the corresponding position of the fixed frame 100. A roller 600 is arranged in the sliding recess to reduce sliding friction resistance.

[0081] In some examples, a sealing strip 700 can be added between the sliding recess sidewall and the sliding protrusion sidewall. This sealing strip 700, without hindering the push-pull operation, forms a synergistic seal with the sealing strips at other locations, further improving the sealing performance of the horizontal gap during the push-pull process and enhancing the overall airtightness.

[0082] The roller 600 is connected to the bottom of the push-pull fan body 210. Through the push-pull operation, the roller 600 of the push-pull fan body 210 rotates and the slide rail 211 of the push-pull fan body 210 moves relative to the slide rail groove 110 of the fixed frame 100.

[0083] Understandably, referring to Figure 2 In some examples of this utility model, the fixed frame 100 is provided with slide rail grooves 110 in the horizontal left and right directions. Two first sealing pads 310 are provided in one slide rail groove 110, and one first sealing pad 310 is provided in the other slide rail groove 110. As a result, the second sealing strip 410 between the two push-pull fan bodies 210 is located exactly between the two adjacent first sealing pads 310. This arrangement forms a multi-seal structure, thereby further improving the sealing effect.

[0084] Understandably, referring to Figure 1 , Figure 3 and Figure 4 In some examples of this utility model, a third sealing structure 500 for sealing the vertical gap between each push-pull fan body 210 and the fixed frame 100 is provided.

[0085] Reference Figure 3 and Figure 4 The third sealing structure 500 includes a first vertical sealing strip 510 and a second vertical sealing strip 520. The first vertical sealing strip 510 is located in the vertical position of the fixed frame 100, and the second vertical sealing strip 520 is located in the vertical position of the push-pull fan body 210, and the two are arranged facing each other.

[0086] It is understood that the side wall of the fixed frame 100 is provided with a vertical groove, the first vertical sealing strip 510 is installed in the vertical groove, and the second vertical sealing strip 520 is installed on the side of the push-pull fan body 210. For example, the first vertical sealing strip 510 is installed in the vertical groove on the left side of the fixed frame 100, and the second vertical sealing strip 520 is installed on the left side of the push-pull fan body 210.

[0087] Using the above structure, the third sealing structure 500 achieves precise sealing of the vertical gap between the push-pull fan body 210 and the fixed frame 100 through the coordinated arrangement of the first vertical sealing strip 510 and the second vertical sealing strip 520. The first vertical sealing strip 510 is pre-installed in the vertical position of the fixed frame 100, and the second vertical sealing strip 520 is correspondingly located in the vertical position of the push-pull fan body 210. The two are arranged facing each other to form a "two-way clamping" structure. When the push-pull fan body 210 is closed, the first vertical sealing strip 510 and the second vertical sealing strip 520 directly abut against each other to form a continuous sealing strip, which can effectively prevent air penetration through the vertical gap. At the same time, the facing arrangement design allows the first vertical sealing strip 510 and the second vertical sealing strip 520 to be uniformly compressed vertically when under pressure, avoiding sealing failure caused by local stress concentration, improving the stability and durability of the vertical seal, and further enhancing the overall airtightness.

[0088] It is understood that in some examples of this utility model, the first sealing strip 330 in the horizontal direction is slightly squeezed with the second sealing strip 410 between the two sliding sashes 210. When the sliding sash assembly 200 is closed, the first sealing strip 330, the second sealing strip 410, the first vertical sealing strip 510 and the second vertical sealing strip 520 form a complete sealing structure to ensure the airtightness of the entire sliding window.

[0089] It is understood that, in some examples of this utility model, the design process of the above-mentioned sliding window is as follows:

[0090] Based on the length of the push-pull fan body 210, the length and slope of the wedge-shaped first sealing pad 310 and the second sealing pad 320 are designed respectively. The gap between the first sealing pad 310 and the second sealing pad 320 is reserved to be 5 to 8 mm.
