Description

Technical Field

[0001] This invention belongs to the field of door and window hardware systems, and specifically relates to a side-pressure window anti-misoperation hardware system. Background Technology

[0002] Side-press windows achieve lateral sealing between the window sash and frame through a multi-point locking mechanism. They are primarily used in building environments with high requirements for airtightness, watertightness, and sound and thermal insulation performance, offering advantages in overall sealing performance compared to conventional casement windows. Because the sealing function of side-press windows relies on the precise displacement and final compression state of the window sash during the closing process, they require high installation precision and high rigidity and processing quality of the frame and sash profiles. The hardware system of side-press windows typically requires the use of high-end profiles with regular structures and precise grooves. Furthermore, the hardware system of side-press windows is complex, typically including an upper pulley assembly, corner assembly, locking point assembly, handle assembly, lower pulley assembly, and center lock assembly. These components are connected as a whole by multiple transmission rods, and through precise linkage and transmission between the components, the sliding, locking, and opening actions of the side-press window are achieved. During locking or unlocking, the side-press window needs to move towards the interior or exterior. If the user makes a mistake while operating the handle of the side-pressure window, it may cause wear and tear on the parts, transmission failure, or even damage to the hardware system, affecting the normal service life of the side-pressure window. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a side-pressure window anti-misoperation hardware system to address the shortcomings of the prior art. This hardware system can realize the side-pressure window locking method of unlocking first and then driving, thereby eliminating misoperation from the hardware system structure and ensuring the transmission accuracy and service life of the side-pressure window hardware system.

[0004] The technical solution adopted by this invention to solve the above-mentioned technical problems is as follows: a side-pressure window anti-misoperation hardware system, comprising an upper pulley assembly, a corner assembly, a locking point assembly, a handle assembly, a lower pulley assembly, and a central lock assembly connected by a transmission rod. The upper pulley assembly and the lower pulley assembly are respectively installed on the upper and lower sides of the window sash profile. The corner assembly is installed at the corner of the window sash profile. The handle assembly includes a handle and a lock box. The locking point assembly and the handle assembly are installed on one side of the window sash profile. The central lock assembly is installed on the other side of the window sash profile. A lock seat adapted to the locking point assembly is fixed on the window frame profile. The locking point assembly includes a lock body, a fixing seat, and an anti-misoperation device. The inner side of the fixing seat is fixed to the window sash profile. A lock hook is fixed to the upper part of the lock body, and the lower part of the lock body is movably inserted into the inner side of the fixed base. The anti-misoperation device is rotatably installed on the outer side of the fixed base. A pressing part is provided on the side of the anti-misoperation device facing away from the lock body, and a hook part is provided on the side of the anti-misoperation device facing the lock body. A limiting boss is provided on the side of the lock body facing the anti-misoperation device. A sliding groove is provided on the lock base, and a roller is provided in the sliding groove. Before the side window is locked, the hook part is located directly above the limiting boss. When the side window is locked by operating the handle, the lock base presses against the pressing part, causing the anti-misoperation device to rotate and the hook part to move away from above the limiting boss. The lock body can then move upward until the lock hook catches the roller, thereby locking the side window.

[0005] The side-pressure window anti-misoperation hardware system of this invention achieves the technical effects of effectively preventing misoperation and improving system reliability. Specifically, before the side-pressure window is locked, i.e., when the side-pressure window is open, the hook part is located directly above the limiting boss, acting as a limit to prevent the lock body from moving upward, thereby preventing forced transmission and wear of components due to misoperation of the handle. When the side-pressure window needs to be closed, during the process of locking the side-pressure window by operating the handle, the anti-misoperation device moves horizontally to contact the lock seat. Utilizing the lever principle, the lock seat first presses against the pressing part of the anti-misoperation device, causing the anti-misoperation device to rotate and drive the hook part away from above the limiting boss. At this time, the lock body can then move upward under the drive of the handle until the lock hook catches the roller, thereby locking the side-pressure window. The side-pressure window anti-misoperation hardware system of this invention, through the innovative structural design of the locking point assembly and lock seat, realizes a side-pressure window locking method of unlocking first and then transmission, eliminating misoperation from the hardware system structure and ensuring the transmission accuracy and service life of the side-pressure window hardware system.

[0006] Preferably, the anti-misoperation device is rotatably mounted on the outside of the fixed base via a pin. A return spring is connected between the lower part of the anti-misoperation device and the fixed base. The hook part is located at the top of the anti-misoperation device, and the pressing part is located at the bottom of the anti-misoperation device. The anti-misoperation device is installed via a pin and a return spring, resulting in a simple structure that enables automatic reset and buffering, further improving the reliability and service life of the hardware system.

[0007] As a further preferred embodiment, the front end of the top pressure section is threaded with an adjusting screw. The adjusting screw allows adjustment of the activation distance of the anti-misoperation device, ensuring the transmission accuracy of the hardware system. During the side-pressure window locking process, the adjusting screw, as an extension of the top pressure section, directly contacts the lock seat, and the lock seat rotates the anti-misoperation device by pressing the adjusting screw.

[0008] As a further preferred embodiment, the top of the slide groove is a narrow groove that narrows towards the interior. An eccentric rivet is threadedly connected to the top of the lock body. During the locking of the side-pressure window, the head of the eccentric rivet extends into the slide groove, guiding the upward movement of the lock body and limiting its upward travel. The eccentric rivet, in conjunction with the slide groove and the narrow groove at its top, facilitates the movement of the side-pressure window towards the interior, achieving a good side-pressure sealing effect. When it is necessary to open the side-pressure window, the design of the eccentric rivet, slide groove, and narrow groove helps the side-pressure window move towards the exterior, completing the unlocking process. Furthermore, the eccentric rivet design helps improve the fitting accuracy between the locking point assembly and the lock seat, ensuring a good side-pressure sealing effect.

[0009] Preferably, the sliding wheel assembly includes a base plate, a base, a fixing block, and a sliding wheel assembly arranged sequentially from top to bottom. The base plate has one inclined groove and two straight grooves in the left and right directions. Sliding rivets are slidably connected in both straight grooves. The base is fixedly connected to the sliding rivets. The base has a waist-shaped hole in the front-back direction. The fixing block is fixed to the base. The fixing block has a mounting hole in the middle. Two brushes arranged in the front-back direction are embedded in the fixing block. The sliding wheel assembly includes a bracket and two sliding wheels and a bearing wheel mounted on the bracket. The axis of each sliding wheel is in the front-back direction, and the axis of the bearing wheel is in the up-down direction. The wheel surface of each sliding wheel is in contact with one of the brushes. The bracket is fixed at the mounting hole. A toggle rod is fixed at the bottom of the bracket. The toggle rod passes through the mounting hole and the waist-shaped hole in sequence and extends into the inclined groove to slide and connect with the base plate. After installation, the bearing wheels are embedded in the grooves at the bottom of the window frame profile, with their wheel surfaces contacting the sides of the grooves to prevent the side-loading window from wobbling back and forth. The two sliding wheels use the grooves at the bottom of the window frame profile as their sliding tracks. These bearing wheels, in conjunction with the sliding wheels, enable reliable sliding of the side-loading door. More importantly, the sliding wheel assembly has a self-cleaning function. During the movement of the side-loading window, whether it's locked inwards or unlocked outwards, a brush removes dirt from the sliding wheels, effectively preventing dust and dirt buildup, keeping the wheels clean, and eliminating jamming, noise, or blockages caused by dirt. This significantly improves the smoothness and stability of the side-loading window during movement, thereby extending its lifespan and enhancing the user experience.

[0010] Preferably, the corner assembly includes a horizontal section and a vertical section that are perpendicular to each other. Both the horizontal and vertical sections have multiple screw holes. A connecting rod is connected to the bottom of the vertical section, and an eccentric locking point is riveted to the connecting rod. The multiple screw holes on both the horizontal and vertical sections of the corner assembly for installing fastening screws ensure that both sections are tightly fitted to the window sash profile, thus preventing the transmission rod from warping or coming off. Furthermore, the eccentric locking point design on the connecting rod improves the connection accuracy between the vertical section of the corner assembly and the transmission rod, ensuring optimal transmission performance.

[0011] Preferably, the number of the upper pulley assembly, locking point assembly, lower pulley assembly, and center lock assembly are all two sets, the number of the corner assembly is three sets, and the number of the handle assembly is one set. In practical applications, the number of the above components can be adjusted according to the length and width dimensions of the side window.

[0012] Compared with existing technologies, the present invention has the following advantages: The side-pressure window anti-misoperation hardware system of the present invention, through the innovative structural design of the locking point assembly and lock seat, achieves a side-pressure window locking method of unlocking first and then transmission, eliminating misoperation from the hardware system structure and ensuring the transmission accuracy and service life of the side-pressure window hardware system. Specifically, before the side-pressure window is locked, i.e., in the open state, the hook part is located directly above the limiting boss, playing a limiting role and preventing the lock body from moving upward, thereby preventing forced transmission and wear of components due to misoperation of the handle; when the side-pressure window needs to be closed, during the process of locking the side-pressure window by operating the handle, the anti-misoperation device moves horizontally to contact the lock seat. Utilizing the lever principle, the lock seat first presses against the pressing part of the anti-misoperation device, causing the anti-misoperation device to rotate and drive the hook part away from above the limiting boss. At this time, the lock body can then move upward under the drive of the handle until the lock hook catches the roller, thereby achieving the locking of the side-pressure window.

[0017] In this embodiment, as Figure 7 and Figure 8 As shown, the sliding wheel assembly 5 includes a base plate 51, a base 52, a fixing block 53, and a sliding wheel assembly 54 arranged sequentially from top to bottom. The base plate 51 is fixed to the window sash profile 71. The base plate 51 has a slanted groove 511 and two straight grooves 512 in the left and right directions.

[0019] The working principle of the side-pressure window anti-misoperation hardware system in the above embodiment: Before the side-pressure window is locked, that is, in the open state of the side-pressure window, the hook part 332 is located directly above the limiting boss 313, such as Figure 3 As shown, it serves as a limit switch to prevent the lock body 31 from moving upwards; when it is necessary to close the side window, during the process of locking the side window by operating the handle, the anti-misoperation device 33 gradually moves horizontally towards the lock seat 30, and after the adjusting screw 335 contacts the lock seat 30, as shown... Figure 4 As shown, the anti-misoperation device 33 continues to move horizontally, and the head of the eccentric rivet 312 extends into the slide groove 301. At the same time, using the lever principle, the lock seat 30 first presses against the adjusting screw 335 of the anti-misoperation device 33, as... Figure 5 As shown, after the anti-misoperation device 33 rotates and drives the hook part 332 to move away from above the limiting boss 313, the lock body 31 can then move upward under the drive of the handle until the lock hook 311 hooks the roller 303, as shown. Figure 6 As shown, this achieves the locking of the side-pressure window. During the upward movement of the lock body 31, the head of the eccentric rivet 312 guides the upward movement of the lock body 31 and limits its upward travel. The above-described locking process of the side-pressure window realizes a locking method of unlocking first and then transmission, eliminating misoperation from the hardware system structure and ensuring the transmission accuracy and service life of the side-pressure window hardware system.
