[0002] After sliding closed, a side-press window can be gradually moved laterally towards the window frame by turning the handle, and is then pressed tightly against the frame by the sealing strip, thus improving the airtightness when closed. The pulley mechanism of the side-press window, in cooperation with the sliding components, can maintain stable sliding within the guide rails of the window frame when the window is closed to the frame. To ensure its transmission stability, existing sliding components are relatively complex and expensive, hindering widespread adoption. Utility Model Content

[0020] This solution discloses a side-pressure window, including a window sash and a window frame, with a pulley mechanism between the window sash and the window frame, and the pulley mechanism having a sliding component for the side-pressure window.

[0021] The sliding assembly of the side-pressure window in this solution uses a C-shaped structure for the sliding seat or sliding bracket, confining the sliding connection between the sliding seat and the sliding bracket within the C-shaped structure. This achieves stable sliding of the sliding bracket while simplifying the structure. The base plate and side plate in the C-shaped structure have the same thickness, facilitating stamping from a single piece of stainless steel and simplifying the manufacturing process. The fact that the base plate and side plate have the same thickness also saves material and costs while ensuring strength requirements. The sliding assembly disclosed in this invention has a simple structure, low cost, and stable function.

[0022] First Embodiment See Figure 1-3 In this embodiment, the side-pressure window uses a sliding assembly 20 to connect to the lower roller assembly 10. A sliding seat 22 is used to connect to the bottom edge of the window sash, and a sliding bracket 21 is used to connect to the lower roller assembly 10. The lower roller assembly 10 includes a pulley frame and a sliding wheel. The sliding bracket 21 connects to the pulley frame, and the pulley frame connects to the sliding wheel. The sliding wheel is used to slide within the bottom edge of the window frame.

[0023] Specifically, the sliding assembly 20 for the side-pressure window includes a sliding seat 22 and a sliding bracket 21. The sliding seat 22 includes a base plate 221, a side plate 222, and a baffle 227. The base plate 221 is used to connect to the window sash. Two side plates 222 are respectively disposed on both sides of the base plate 221. Two baffles 227 are respectively connected to the corresponding side plates 222. The base plate 221, the side plates 222, and the baffles 227 form a C-shaped sliding seat 22. The thickness of the base plate 221 is the same as the thickness of the side plates 222. The sliding bracket 21 is used to connect to the pulley assembly. The sliding bracket 21 slides within the C-shaped sliding seat 22 along the thickness direction of the window sash.

[0024] The C-type sliding seat 22 refers to an open-type groove structure formed by a base plate 221, side plates 222, and baffle 227. It can be formed by stamping or bending metal sheets. This structure restricts the sliding bracket 21 to move only in the thickness direction of the window sash, preventing lateral displacement. The thickness h1 of the base plate 221 is the same as the thickness h2 of the side plates 222; for example, aluminum alloy sheets of equal thickness can be used, simplifying processing and ensuring uniform stress distribution on the sliding seat 22, reducing the risk of localized deformation. Specifically, the base plate 221 is fixed to the top or bottom edge of the window sash by fasteners 224. The side plates 222 extend perpendicularly to the base plate 221, and baffles 227 bend inward from the ends of the side plates 222 to form limiting edges. The opening side of the C-shaped structure faces the outer side of the window sash, and the sliding bracket 21 is embedded in the opening groove and slides along its thickness. The base plate 221 and side plates 222 are made of the same thickness material, such as 1mm-5mm metal plates, preferably 2mm-3mm stainless steel plates, to ensure the sliding seat 22 maintains structural stability when bearing the load of the pulley assembly. The sliding assembly 20 of this design occupies little space and has low material costs. The thickness of the base plate 221 is the same as the thickness of the side plates 222, which saves material and costs while ensuring strength requirements.

[0025] In this embodiment, the base plate 221 extends at both ends along the thickness direction of the window sash with positioning and mounting portions 223. The positioning and mounting portions 223 are provided with fasteners 224, which are used to fix the sliding seat 22 to the window sash. Specifically, the positioning and mounting portions 223 are provided with fastening holes, and the fasteners 224 are fixed inside the window sash profile after passing through the fastening holes.

[0026] In this design, the fasteners 224 are located at both ends of the base plate 221 along the thickness direction of the window sash and are close to the junction area between the base plate 221 and the side plate 222. This can shorten the length of the base plate 221 and reduce the area occupied, while also dispersing the stress between the base plate 221 and the side plate 222, thereby strengthening the base plate 221 and the side plate 222 and preventing deformation of the base plate 221 and the side plate 222.

[0027] In the existing sliding assembly 20, the positioning and mounting portion 223 of the sliding seat 22 needs to extend along the length of the window sash to provide fastening holes, resulting in a large structural space occupation and the fastener 224 being far from the sliding area, which easily leads to deformation of the sliding seat 22. This solution, however, uses a compact fit between the C-shaped sliding bracket 21 and the sliding seat 22 to concentrate the sliding connection area in the thickness direction of the window sash, eliminating the need for additional extension of the mounting portion and thus reducing space occupation. At the same time, the equal thickness design of the base plate 221 and the side plate 222 enhances the overall rigidity of the sliding bracket 21, making it less prone to twisting or displacement during sliding.

[0028] This application solves the problems of excessive space occupation and easy structural deformation caused by the excessive extension of the installation part in the existing sliding assembly 20. The compact design of the C-type sliding bracket 21 reduces space requirements, and the use of plates of uniform thickness improves structural stability, enabling the pulley assembly to slide more reliably along the guide rail when the side window is closed, thereby improving the clamping effect between the sealing strip and the window frame.

[0029] Second Embodiment See Figure 4-6In this embodiment, the side-pressure window uses a sliding assembly 20 to connect to the lower roller assembly 10. A sliding seat 22 is used to connect to the bottom edge of the window sash, and a sliding bracket 21 is used to connect to the lower roller assembly 10. The lower roller assembly 10 includes a pulley frame and a sliding wheel. The sliding bracket 21 connects to the pulley frame, and the pulley frame connects to the sliding wheel. The sliding wheel is used to slide within the bottom edge of the window frame.

[0030] Specifically, the sliding assembly 20 for the side-pressure window includes a sliding bracket 21 and a sliding seat 22. The sliding bracket 21 includes a base plate 2101, a side plate 2102, and a baffle. The base plate 2101 is used to connect the pulley assembly. The two side plates 2102 are respectively located on both sides of the base plate 2101. The two baffles are respectively connected to the corresponding side plates 2102. The base plate 2101, the side plates 2102, and the baffles form a C-shaped sliding bracket 21. The thickness h3 of the base plate 2101 is the same as the thickness h4 of the side plates 2102. The sliding seat 22 is used to connect to the window sash. The C-shaped sliding bracket 21 and the sliding seat 22 are slidably connected in the thickness direction of the window sash.

[0031] The sliding bracket 21 includes a base plate 2101, side plates 2102, and baffles. The base plate 2101 is used to connect the pulley assembly. The two side plates 2102 are respectively located on both sides of the base plate 2101. The two baffles are respectively connected to the corresponding side plates 2102. The base plate 2101, side plates 2102, and baffles form a C-shaped sliding bracket 21. The thickness of the base plate 2101 is the same as the thickness of the side plates 2102. The sliding seat 22 is used to connect to the window sash. The C-shaped sliding bracket 21 and the sliding seat 22 are slidably connected in the thickness direction of the window sash.

[0032] The base plate 2101 refers to the plate-like structure that forms the basic bearing surface of the sliding bracket 21, directly bearing the installation load of the pulley assembly. The side plate 2102 refers to the plate-like structure extending perpendicular to the base plate 2101, forming the lateral support structure of the sliding bracket 21. The fact that the thickness of the base plate 2101 and the side plate 2102 are the same means that they are consistent in material thickness. Specifically, this can be achieved by using equal-thickness plates to ensure uniform deformation of all parts of the sliding bracket 21 under stress. The equal-thickness design of the base plate 2101 and the side plate 2102 facilitates integral forming with the base plate 2101 through stamping or bending processes, simplifying the manufacturing process.

[0033] The C-type sliding bracket 21 forms an open-type sliding groove structure through the combination of a base plate 2101, two side plates 2102, and baffles. The base plate 2101 and side plates 2102 are made of the same thickness material, such as 1mm-5mm metal plates, preferably 2mm-3mm stainless steel plates, to ensure the sliding seat 22 maintains structural stability when bearing the load of the pulley assembly. This design's sliding assembly 20 occupies little space and has low material costs. The thickness of the base plate 2101 is the same as the thickness of the side plates 2102, which saves material and reduces costs while ensuring strength requirements.

[0034] In the existing sliding assembly 20, the positioning and mounting portion 223 of the sliding seat 22 needs to extend along the length of the window sash to provide fastening holes, resulting in a large structural space occupation and the fastener 224 being far from the sliding area, which easily leads to deformation of the sliding seat 22. This solution, however, uses a compact fit between the C-shaped sliding bracket 21 and the sliding seat 22 to concentrate the sliding connection area in the thickness direction of the window sash, eliminating the need for additional extension of the mounting portion and thus reducing space occupation. Simultaneously, the equal thickness design of the base plate 2101 and the side plate 2102 enhances the overall rigidity of the sliding bracket 21, making it less prone to twisting or displacement during sliding.

[0035] Third Embodiment See Figure 7-9 In this embodiment, the side-pressure window is connected to the upper pulley assembly 10B via a sliding assembly 20. A sliding seat 22 is used to connect to the bottom edge of the window sash, and a sliding bracket 21 is used to connect to the upper pulley assembly 10B. The upper pulley assembly 10B includes several guide wheels, which are slidably connected to the top edge of the window frame.

[0036] Specifically, the sliding assembly 20 for the side-pressure window includes a sliding seat 22 and a sliding bracket 21. The sliding seat 22 includes a base plate 221, a side plate 222, and a baffle 227. The base plate 221 is used to connect to the window sash. Two side plates 222 are respectively disposed on both sides of the base plate 221. Two baffles 227 are respectively connected to the corresponding side plates 222. The base plate 221, the side plates 222, and the baffles 227 form a C-shaped sliding seat 22. The thickness h5 of the base plate 221 is the same as the thickness h6 of the side plates 222. The sliding bracket 21 is used to connect to the pulley assembly. The sliding bracket 21 slides in the C-shaped sliding seat 22 along the thickness direction of the window sash.

[0037] The C-type sliding seat 22 refers to an open-type groove structure formed by a base plate 221, side plates 222, and baffle 227. It can be formed by stamping or bending metal sheets. This structure restricts the sliding bracket 21 to move only in the thickness direction of the window sash, preventing lateral displacement. The base plate 221 and side plates 222 have the same thickness; for example, aluminum alloy sheets of equal thickness can be used, simplifying processing and ensuring uniform stress distribution on the sliding seat 22, reducing the risk of localized deformation. Specifically, the base plate 221 is fixed to the top or bottom edge of the window sash by fasteners 224. The side plates 222 extend perpendicularly to the base plate 221, and baffles 227 bend inward from the ends of the side plates 222 to form limiting edges. The opening side of the C-shaped structure faces the outer side of the window sash, and the sliding bracket 21 is embedded in the opening groove and slides along its thickness. The base plate 221 and side plates 222 are made of the same thickness material, such as 1mm-5mm metal plates, preferably 2mm-3mm stainless steel plates, to ensure the sliding seat 22 maintains structural stability when bearing the load of the pulley assembly. The sliding assembly 20 of this design occupies little space and has low material costs. The thickness of the base plate 221 is the same as the thickness of the side plates 222, which saves material and costs while ensuring strength requirements.

[0038] In this embodiment, the base plate 221 extends at both ends along the thickness direction of the window sash with positioning and mounting portions 223. The positioning and mounting portions 223 are provided with fasteners 224, which are used to fix the sliding seat 22 to the window sash. Specifically, the positioning and mounting portions 223 are provided with fastening holes, and the fasteners 224 are fixed inside the window sash profile after passing through the fastening holes.

[0039] In this design, the fasteners 224 are located at both ends of the base plate 221 along the thickness direction of the window sash and are close to the junction area between the base plate 221 and the side plate 222. This can shorten the length of the base plate 221 and reduce the area occupied, while also dispersing the stress between the base plate 221 and the side plate 222, thereby strengthening the base plate 221 and the side plate 222 and preventing deformation of the base plate 221 and the side plate 222.

[0040] Fourth embodiment See Figure 1-3 and Figure 10-16 This embodiment discloses a sliding wheel mechanism, including a sliding wheel assembly 10 and a sliding component as described in the first embodiment. The sliding wheel assembly 10 includes a pulley frame 11 and sliding wheels 12. Two sets of sliding wheels 12 are symmetrically connected to both ends of the pulley frame 11, and the sliding wheels 12 are used to slide onto the window frame 2 profile guide rail. One end of the sliding component 20 is used to connect to the window sash 3 profile, and the other end of the sliding component 20 is connected to the pulley frame 11. The two sets of sliding wheels 12 are located on both sides of the sliding component 20, which are used to reduce the height of the side-pressure pulley mechanism 1.

[0041] Through the cooperative design of the sliding roller assembly 10 and the sliding assembly 20, the sliding roller assembly 10 can be stably slidably connected to the window frame 2 during the side pressure of the window sash 3 against the window frame 2. Two sets of sliding rollers 12 are arranged on both sides of the sliding assembly 20, so that the sliding assembly 20 is sunk as low as possible into the sliding roller assembly 10, effectively reducing the overall height of the mechanism, reducing the space occupied between the window sash 3 and the window frame 2, improving the sealing performance, and having the advantages of compact structure, smooth operation, and aesthetic appeal.

[0042] This application achieves a flattened design for the side-pressure pulley mechanism 1, reducing the bottom thickness of the window sash 3 profile by approximately 40%. In narrow-frame sliding window applications, this structure results in a more uniform distribution of contact pressure between the sealing strip and the window frame 2 when the window sash 3 is closed. Simultaneously, the exposed lower pulley assembly 10 is aligned with the guide rail of the window frame 2, visually creating a concealed pulley effect, which meets the modern architectural design requirements for simplified door and window components.

[0043] It should be noted that the sliding wheel 12 in this solution can be a single sliding wheel 12 structure with a single rail, or it can be a combination structure of two sliding wheels 12 with a double rail.

[0044] In this embodiment, the sliding assembly 20 includes a sliding bracket 21 and a sliding seat 22. The pulley bracket 11 is connected to the sliding bracket 21, and the sliding seat 22 is used to connect to the window sash 3 profile. The sliding bracket 21 and the sliding seat 22 are slidably connected in a direction perpendicular to the sliding of the pulley 12. This solution separates the load-bearing function from the adjustment function by sliding the sliding bracket 21 and the sliding seat 22 in a vertical direction. While maintaining the lateral pressure accuracy, it eliminates structural redundancy, allowing the window sash 3 to be closer to the window frame 2 when closed.

[0045] In this embodiment, the bottom of the sliding wheel 12 is used to slide onto the window frame 2 profile guide rail, and the top of the sliding wheel 12 is higher than the top surface of the sliding bracket 21 and lower than the top surface of the sliding seat 22. The top of the pulley in the transmission side-pressure pulley mechanism 1 is usually lower than the bottom surface of the sliding seat 22 because the sliding seat 22 needs to extend its mounting position in the sliding direction of the pulley, thus the length of the sliding seat 22 is relatively long. This solution simplifies the structure of the sliding seat 22, making the top of the sliding wheel 12 higher than the top surface of the sliding bracket 21, i.e., located on both sides of the sliding seat 22. This allows the sliding seat 22 and the sliding bracket 21 to be lowered as much as possible between the two sets of sliding wheels 12. While keeping the radius of the sliding wheel 12 unchanged, the height of the sliding seat 22 is greatly reduced, making the structure of the side-pressure pulley mechanism 1 simpler and occupying less space. It should also be noted that the top of the sliding wheel 12 is lower than the top of the sliding seat 22. The top of the sliding seat 22 connects with the side-pressure transmission component 30, and the sliding wheel 12 cannot be higher than the height of the sliding seat 22 to avoid interference with the side-pressure transmission component 30.

[0046] In this embodiment, the sliding bracket 21 includes a sliding roller 211 and a connecting body 212. One side of the sliding roller 211 is connected to the connecting body 212, and the other side of the sliding roller 211 makes rolling contact with the sliding seat 22. By replacing the sliding friction contact between the connecting seat 22 and the connecting body 212 with rolling contact, friction can be effectively reduced, resulting in lighter sliding and enhanced user experience.

[0047] The connecting body 212 includes a sliding part 2121 and a connecting part 2122 that is perpendicular to both sides of the sliding part 2121 and bends towards the pulley frame 11. The sliding part 2121 is slidably connected to the base plate and slides within the sliding area. The connecting part 2122 is used to connect to the pulley frame 11. The connecting part 2122 is an inverted trapezoidal shape extending towards the pulley frame 11. The sliding part 2121 and the connecting part 2122 are a simple structure integrally formed, which is easy to mold.

[0048] In this embodiment, the sliding seat 22 includes a base plate 221, side plates 222 extending from both ends of the base plate 221, and a baffle 227. The base plate 221, side plates 222, and baffle 227 are integrally formed C-shaped sliding seats. The base plate 221 is in rolling contact with the sliding roller 211. The side plates 222 and baffle 227 are sleeved on the outside of the sliding part 2121 to limit the sliding part 2121 in the sliding area. The sliding roller 211 is used to reduce the sliding friction. The sliding part 2121 is used to cooperate with the side plates 222 to limit the sliding area of ​​the sliding bracket 21.

[0049] The pulley frame 11 is provided with a groove 111 for accommodating the side plate 222 and the baffle 227, allowing the side plate 222 to sink into the pulley frame 11. The groove 111 further facilitates the sinking of the side plate 222, reducing the vertical space occupied. It should be noted that the two sets of sliding wheels 12 are fixedly connected to the sliding bracket 21 with the pulley frame 11 as the installation center axis, so that the two sets of sliding wheels 12 are symmetrically connected with the sliding bracket 21 as the center axis. The side plate 222 and the baffle 227 do not contact the groove 111, reserving space for the sliding wheels 12 to offset in the height direction, facilitating the self-adjustment of the two sets of sliding wheels 12 to different heights.

[0050] In this embodiment, positioning mounting portions 223 extend from both sides of the sliding seat 22 along the sliding direction of the sliding frame. The positioning mounting portions 223 are equipped with fasteners 224, which are used to fix the sliding seat 22 to the window sash 3 profile. Traditionally, both ends of the sliding seat 22 have mounting portions extending along the sliding direction of the lower roller assembly 10, preventing the sliding seat 22 from sinking between the two sets of sliding rollers 12. This solution simplifies the structure of the sliding bracket 21, narrowing its width while maintaining the same width for the side plate 222 on the sliding seat 22, thus shortening the sliding stroke of the sliding bracket 21. This allows for the placement of positioning mounting portions 223 on both sides of the sliding seat 22. Specifically, the positioning mounting portions 223 are positioned near the curved position of the side plate 222 to ensure load-bearing performance. Since the main force between the sliding seat 22 and the sliding bracket 21 originates from the sliding direction of the sliding bracket 21, placing the positioning mounting portions 223 in the sliding direction effectively improves the installation strength of the sliding seat 22.

[0051] In this embodiment, the sliding roller assembly 10 further includes a guide wheel 13, which is connected to the pulley frame 11 and is used to make rolling contact with the window frame 2 profile to guide the pulley frame 11. The guide wheel 13 is directly mounted on the side extension arm of the pulley frame 11. When the sliding roller assembly 10 slides along the guide rail of the window frame 2 profile, the guide wheel 13 forms rolling contact with the side wall of the window frame 2 profile, replacing traditional sliding friction with rolling friction to reduce motion resistance. During the sliding process, the contact force applied by the guide wheel 13 to the side wall of the window frame 2 profile forms a lateral constraint, limiting the offset of the pulley frame 11 in the direction perpendicular to the sliding direction.

[0052] In this embodiment, the side-pressure pulley mechanism 1 further includes a side-pressure transmission assembly 30, which includes a side-pressure column 31 and a transmission bar 32. The transmission bar 32 is connected to external transmission hardware and has a side-pressure inclined groove 321. The side-pressure column 31 is connected to the sliding bracket 21 and passes through the transmission seat before being inserted into the side-pressure inclined groove 321. When the external transmission hardware drives the transmission bar 32 to move along the sliding direction of the sliding wheel 12, the side-pressure column 31 slides along the side-pressure inclined groove 321 under the constraint of the guide hole of the transmission seat. Due to the inclined angle of the inclined groove, the linear motion of the transmission bar 32 is converted into the inclined motion of the sliding bracket 21. This motion conversion method directly acts on the sliding wheel 12 of the lower pulley assembly 10. The cooperation between the transmission bar 32 and the side-pressure column 31 ensures the motion stability during the displacement conversion process, while the adjustability of the inclined groove angle allows the sealing strip clamping force to be adaptively adjusted according to the actual working conditions.

[0053] The transmission bar 32 forms a sliding engagement with the side pressure column 31 through the side pressure groove 321. When the external transmission hardware drives the transmission bar 32 to move, the side pressure column 31 slides along the groove, causing the sliding bracket 21 to move in a direction perpendicular to the sliding direction of the pulley, thereby adjusting the contact pressure between the pulley assembly 10 and the window frame 2 profile. After the second positioning part 42 of the pre-positioning member 40 is inserted into the transmission bar 32, it restricts the lateral displacement of the transmission bar 32 during the installation process, ensuring that the initial position of the side pressure column 31 and the side pressure groove 321 are accurately aligned.

[0054] In this embodiment, the side-pressure pulley mechanism 1 further includes a pre-positioning component 40, which includes a first positioning part 41 and a second positioning part 42. The second positioning part 42 is inserted into the transmission bar 32, and the first positioning part 41 is inserted into the sliding seat 22. During assembly, the second positioning part 42 is first inserted into the positioning hole on the side of the transmission bar 32, and then the first positioning part 41 is inserted vertically into the groove 111 on the side wall of the sliding seat 22, thus fixing the relative position between the sliding seat 22 and the transmission bar 32. This double insertion relationship allows the transmission bar 32 and the sliding seat 22 to form a mutual constraint during installation, maintaining their relative positional accuracy without the need for additional adjusting bolts or positioning blocks.

[0055] During installation, the sliding seat 22 is fixed inside the window sash 3 profile, and the lower roller assembly 10 is embedded in the track of the window frame 2 profile. The first positioning part 41 of the pre-positioning member 40 is inserted into the positioning hole of the sliding bracket 21, and the second positioning part 42 is inserted into the positioning groove of the transmission bar 32, so that the two maintain a fixed distance in the sliding direction of the pulley. At this time, the side pressure transmission assembly 30 is operated to drive the sliding bracket 21 to move, which drives the lower roller assembly 10 to slide along the window frame 2 profile. After debugging, the pre-positioning member 40 is removed to ensure that the mechanism operates normally. This application pre-fixes the relative positions of the sliding assembly 20 and the side pressure transmission assembly 30 during the installation stage to avoid the waste of time caused by repeated debugging. The plug-in structure of the pre-positioning member 40 ensures the consistency of the initial positions of the two in the direction of pulley movement, reducing the problem of pulley jamming caused by assembly deviation. After installation, removing the pre-positioning member 40 will not affect the operation of the mechanism, achieving a balance between rapid positioning and reliable transmission.

[0056] In this embodiment, the sliding seat 22 is provided with a positioning protrusion 225, which is used to insert into the window sash 3 profile to achieve pre-positioning in the sliding direction perpendicular to the sliding roller assembly 10. During the installation process, the positioning protrusion 225 and the window sash 3 profile are engaged to achieve automatic positioning in the width direction, and the pre-positioning component 40 achieves positioning in the length direction. The two are combined to achieve precise positioning and installation of the sliding assembly 20.
