Description

Technical Field

[0001] This invention belongs to the technical field of building door and window hardware accessories, and relates to a miniature window hardware sealing system. Background Technology

[0002] In the current building window and door market, miniature windows are widely used in bathrooms, kitchens, balconies, and small office spaces due to their compact structure and small footprint. However, conventional miniature windows on the market currently have significant defects in sealing performance. Their sealing structure design is relatively simple, usually only equipped with upper and lower hinges and straight-handle side sealing components. The sealing scheme on the hinge side has obvious omissions and fails to form a complete sealing system.

[0003] This incomplete sealing design directly leads to the following problems: First, the entire window cannot achieve a full-range seal, creating a weak sealing area on the hinge side. External wind, rain, dust, etc., can easily seep into the room through this area, seriously affecting the comfort of the indoor environment. Second, when the height of the miniature window is relatively high, the problem of lacking effective sealing support on one side becomes more prominent. Not only does the sealing performance further decline, but uneven stress may also reduce the structural stability of the window.

[0004] To address the aforementioned issues, there is an urgent need for a miniature window hardware sealing system that is easy to install and has excellent sealing performance. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a miniature window hardware sealing system.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions: A miniature window hardware sealing system includes a handle assembly, a transmission assembly, a locking assembly, and a hinge assembly. Each assembly is adapted to the profile structure of the miniature window. The handle assembly, transmission assembly, locking assembly, and hinge assembly are hidden inside the profile through a pre-set installation groove. The transmission assembly includes a main transmission rod, a first driven transmission rod, a second driven transmission rod, and a linkage connector. The main transmission rod and the second driven transmission rod are arranged along the height direction of the window sash, and the main transmission rod and the second driven transmission rod are respectively located on both sides of the window sash. The first driven transmission rod is arranged along the height direction of the window sash and is located at the top of the window sash. The linkage connector includes a first corner bracket and a second corner bracket. The top of the main transmission rod is connected to the first driven transmission rod through the first corner bracket, and the other end of the first driven transmission rod is connected to the second driven transmission rod through the second corner bracket. The middle part of the main transmission rod is connected to the handle assembly, forming a linkage structure for the entire window.

[0007] In the aforementioned miniature window hardware sealing system, the locking assembly includes multiple locking points and matching lock seats. The locking points include a main locking point fixed to the main drive rod, a first auxiliary locking point fixed to the first driven drive rod, and a second auxiliary locking point fixed to the second driven drive rod. The main locking point, the first auxiliary locking point, and the second auxiliary locking point correspond one-to-one with the lock seats on the window frame.

[0008] In the aforementioned miniature window hardware sealing system, the handle assembly includes a handle body, a rotating shaft, a base, and a drive assembly. The base is fixedly installed on a preset mounting position on the window sash profile by bolts, and the handle body is rotatably connected to the base via the rotating shaft.

[0009] In the aforementioned miniature window hardware sealing system, the drive assembly includes a drive gear fixed to the bottom of the rotating shaft and a driven rack fixed to the side wall of the main drive rod. The drive gear and the driven rack are meshed together. When the handle body rotates, the rotating shaft drives the drive gear to rotate, and the drive gear drives the main drive rod to move along the height direction of the window sash through rack transmission.

[0010] In the aforementioned miniature window hardware sealing system, a limiting block and a U-shaped elastic clamp are fixedly installed on the rotating shaft. The open end of the U-shaped elastic clamp faces the limiting block, and the inner sidewall of the U-shaped elastic clamp is tightly fitted with the sidewall of the limiting block. The circumferential sidewall of the limiting block is provided with two symmetrically distributed arc-shaped grooves, and the inner sidewall of the U-shaped elastic clamp is provided with arc-shaped protrusions that are adapted to the arc-shaped grooves at corresponding positions.

[0011] In the aforementioned miniature window hardware sealing system, the hinge assembly includes an upper hinge and a lower hinge, which are respectively installed at the top and bottom of the window sash. Each hinge includes a fixed leaf fixedly connected to the window frame and a movable leaf fixedly connected to the window sash. The fixed leaf and the movable leaf are hinged together by a pivot.

[0012] In the aforementioned miniature window hardware sealing system, a connecting part is provided at the top of the main drive rod. The connecting part is a rectangular boss extending outward along the top end face of the main drive rod. A cylindrical insert is provided at the center of the boss. One end of the first corner device is provided with a cylindrical connecting hole that matches the cylindrical insert. The cylindrical insert is inserted into the cylindrical connecting hole and fastened by an internal hex bolt.

[0013] In the aforementioned miniature window hardware sealing system, the other end of the first corner unit is provided with an L-shaped adapter arm, the end of which is provided with a circular mounting hole, and the end of the first driven transmission rod is provided with a cylindrical connector adapted to the circular mounting hole, the cylindrical connector being inserted into the circular mounting hole.

[0014] In the aforementioned miniature window hardware sealing system, the main locking point, the first auxiliary locking point, and the second auxiliary locking point each include a movable base and a fixing bolt. The movable base has a sliding groove inside. The main locking point, the first auxiliary locking point, and the second auxiliary locking point are respectively installed on the main drive rod, the first driven drive rod, and the second driven drive rod through the sliding groove. The fixing bolt is installed on the movable base, and one end of the fixing bolt abuts against each drive rod.

[0015] In the aforementioned miniature window hardware sealing system, the handle assembly also includes a decorative cover that covers the outer surface of the base, with its edge flush with the surface of the window sash profile.

[0016] Compared with existing technologies, the advantages of this invention are: 1. This invention forms a concealed linkage sealing system adapted to miniature window profiles by using a handle assembly, a transmission assembly, a locking assembly, and a hinge assembly. It effectively solves the problem of weak side sealing of traditional miniature window hinges. The even distribution of multiple locking points improves the structural stability of the entire window and avoids sealing failure caused by uneven stress in high-profile windows.

[0017] 2. The transmission component of this invention adopts a combination design of a main transmission rod, a first driven transmission rod, a second driven transmission rod, and a cornering device, realizing the synchronous linkage of the entire window locking points during handle operation. When the handle body is rotated, the drive gear drives the main transmission rod to move along the height direction through rack and pinion transmission. The top of the main transmission rod drives the first driven transmission rod to move laterally through the first cornering device. The first driven transmission rod then moves longitudinally through the second cornering device in conjunction with the second driven transmission rod, ultimately making the main locking point, the first auxiliary locking point, and the second auxiliary locking point precisely engage with the window frame lock seat, forming a multi-dimensional locking and sealing.

[0018] 3. All components of this invention are hidden inside the profile, which not only maintains the compact and beautiful shape of the miniature window, but also reduces the corrosion of the hardware by the external environment and extends the service life. Compared with the single sealing structure of traditional miniature windows, the sealing system of this invention has significantly improved the performance of windproof, rainproof and dustproof, and can better meet the use needs of humid and dusty environments such as bathrooms and kitchens.

[0019] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0028] The invention will now be further described with reference to the accompanying drawings.

[0029] like Figure 1-7As shown, a miniature window hardware sealing system includes a handle assembly 1, a transmission assembly 2, a locking assembly 3, and a hinge assembly. Each component is adapted to the profile structure of the miniature window. The handle assembly 1, transmission assembly 2, locking assembly 3, and hinge assembly are hidden inside the profile through a pre-set installation groove 4. The transmission assembly 2 includes a main transmission rod 6, a first driven transmission rod 7, a second driven transmission rod 8, and a linkage connector 9. The main transmission rod 6 and the second driven transmission rod 8 are arranged along the height direction of the window sash 5, and the main transmission rod 6 and the second driven transmission rod 8 are connected in series. The transmission rods 8 are located on both sides of the window sash 5. The first driven transmission rod 7 is set along the height direction of the window sash 5 and is located at the top of the window sash 5. The linkage connector 9 includes a first corner bracket 10 and a second corner bracket 11. The top of the main transmission rod 6 is connected to the first driven transmission rod 7 through the first corner bracket 10. The other end of the first driven transmission rod 7 is connected to the second driven transmission rod 8 through the second corner bracket 11. The middle part of the main transmission rod 6 is connected to the handle assembly 1 to form a whole window linkage structure.

[0030] Furthermore, the locking assembly 3 includes multiple locking points and matching lock seats 12. The locking points include a main locking point 13 fixed to the main drive rod 6, a first auxiliary locking point 14 fixed to the first driven drive rod 7, and a second auxiliary locking point 15 fixed to the second driven drive rod 8. The main locking point 13, the first auxiliary locking point 14, and the second auxiliary locking point 15 correspond one-to-one with the lock seats 12 on the window frame 26.

[0031] In this embodiment, when the handle assembly 1 drives the main drive rod 6 to slide up and down along the mounting groove 4, the main drive rod 6 converts the linear motion into a 90° angular motion through the first corner device 10, driving the first driven drive rod 7 to move laterally in sync. The first driven drive rod 7 then changes its direction of motion again through the second corner device 11, driving the second driven drive rod 8 to slide synchronously in the opposite direction to the main drive rod 6. Ultimately, the main locking point 13, the first auxiliary locking point 14, and the second auxiliary locking point 15 extend or retract simultaneously at corresponding positions on the side, top, and other side of the window sash 5, forming a multi-point locking with the lock seat 12 pre-installed on the window frame 26, thereby solving the problem of missing side seals in traditional micro window hinges.

[0032] Furthermore, the handle assembly 1 includes a handle body 16, a rotating shaft 17, a base 18, and a drive assembly 19. The base 18 is fixedly installed on the preset mounting position of the window sash 5 profile by bolts, and the handle body 16 is rotatably connected to the base 18 through the rotating shaft 17.

[0033] In this embodiment, when the user rotates the handle body 16, the handle body 16 drives the rotating shaft 17 to rotate synchronously. The lower end of the rotating shaft 17 extends into the base 18 and is connected to the drive assembly 19, thereby controlling the main drive rod 6 to move along the height direction of the window sash 5.

[0034] Furthermore, the drive assembly 19 includes a drive gear 20 fixed to the bottom of the rotating shaft 17 and a driven rack 21 fixed to the side wall of the main drive rod 6. The drive gear 20 and the driven rack 21 are meshed together. When the handle body 16 rotates, the rotating shaft 17 drives the drive gear 20 to rotate. The drive gear 20 drives the main drive rod 6 to move along the height direction of the window sash 5 through rack transmission.

[0035] In this embodiment, the teeth of the driving gear 20 mesh with the tooth grooves of the driven rack 21. When the handle body 16 rotates 90° clockwise, the driving gear 20 rotates accordingly and pushes the driven rack 21 upward. The main drive rod 6 rises synchronously along the mounting groove 4 of the window sash 5, causing the main locking point 13 to be embedded in the lock seat 12 at the corresponding position of the window frame 26. At the same time, the first corner device 10 at the top of the main drive rod 6 converts the vertical movement into a horizontal thrust, causing the first driven drive rod 7 to move towards the hinge side. The first auxiliary locking point 14 then engages with the lock seat 12 at the top of the window frame 26. The second corner device 11 at the end of the first driven drive rod 7 then converts the horizontal movement into a vertical pull, pulling the second driven drive rod 8 upward along the mounting groove 4 on the other side of the window sash 5. The second auxiliary locking point 15 engages with the lock seat 12 on the hinge side of the window frame 26, achieving synchronous locking of all four sides of the window.

[0036] Furthermore, a limiting block 22 and a U-shaped elastic clamp 23 are fixedly installed on the rotating shaft 17. The open end of the U-shaped elastic clamp 23 is set towards the limiting block 22, and the inner sidewall of the U-shaped elastic clamp 23 is tightly fitted with the sidewall of the limiting block 22. The circumferential sidewall of the limiting block 22 is provided with two symmetrically distributed arc-shaped grooves, and the inner sidewall of the U-shaped elastic clamp 23 is provided with arc-shaped protrusions that are adapted to the arc-shaped grooves at corresponding positions.

[0037] In this embodiment, when the handle body 16 is in the open state, one of the arc-shaped grooves of the limiting block 22 engages with the arc-shaped protrusion of the U-shaped elastic clamp 23 to form a stable positioning; when the user rotates the handle body 16 to the locked position, the rotating shaft 17 drives the limiting block 22 to rotate synchronously, and the side wall of the limiting block 22 presses against the inner side wall of the U-shaped elastic clamp 23, causing it to undergo elastic deformation. After rotating 90°, the other arc-shaped groove engages with the arc-shaped protrusion again.

[0038] Furthermore, the hinge assembly includes an upper hinge 24 and a lower hinge 25, which are respectively installed at the top and bottom of the window sash 5, and each includes a fixed leaf 27 fixedly connected to the window frame 26 and a movable leaf 28 fixedly connected to the window sash 5. The fixed leaf 27 and the movable leaf 28 are hinged together by a pivot.

[0039] Furthermore, the top of the main drive rod 6 is provided with a connecting part 29, which is a rectangular boss extending outward along the top end face of the main drive rod 6. A cylindrical insert 30 is provided at the center of the boss. One end of the first corner device 10 is provided with a cylindrical connecting hole that is adapted to the cylindrical insert 30. The cylindrical insert 30 is inserted into the cylindrical connecting hole and fastened by an internal hex bolt.

[0040] In this embodiment, the rectangular boss at the top of the main drive rod 6 forms a surface contact with the end of the first angler 10. With the precise engagement of the cylindrical insert 30 and the connecting hole, the connection is effectively prevented from loosening due to force deviation during transmission. The hexagonal socket bolt is screwed into the side of the first angler 10 and passes through the central threaded hole of the cylindrical insert 30, which strengthens the fixing effect between the connecting part 29 and the first angler 10, ensuring that the vertical movement of the main drive rod 6 can be stably transmitted to the first driven drive rod 7.

[0041] Furthermore, the other end of the first corner device 10 is provided with an L-shaped adapter arm 31, the end of the adapter arm 31 is provided with a circular mounting hole, and the end of the first driven transmission rod 7 is provided with a cylindrical connector 32 adapted to the circular mounting hole, the cylindrical connector 32 being inserted into the circular mounting hole.

[0042] In this embodiment, the outer wall of the cylindrical connector 32 is tightly fitted with the inner wall of the circular mounting hole. When the first corner device 10 is driven by the main drive rod 6 to produce a vertical displacement, the L-shaped adapter arm 31 applies a stable thrust to the cylindrical connector 32 through the circular mounting hole, so that the first driven drive rod 7 can slide smoothly along the mounting groove 4 at the top of the window sash 5.

[0043] Furthermore, the main locking point 13, the first auxiliary locking point 14, and the second auxiliary locking point 15 each include a movable base 33 and a fixing bolt 34. The movable base 33 has a sliding groove inside. The main locking point 13, the first auxiliary locking point 14, and the second auxiliary locking point 15 are respectively installed on the main transmission rod 6, the first driven transmission rod 7, and the second driven transmission rod 8 through the sliding groove. The fixing bolt 34 is installed on the movable base 33, and one end of the fixing bolt 34 abuts against each transmission rod.

[0044] In this embodiment, the width of the sliding groove of the movable base 33 is consistent with the cross-sectional width of each transmission rod. During installation, the position of the locking point can be adjusted according to the actual gap between the window sash 5 and the window frame 26: first loosen the fixing bolt 34, push the movable base 33 to slide along the length of the transmission rod until the protruding part of the locking point is aligned with the locking seat 12 on the window frame 26, and then tighten the fixing bolt 34 so that its end presses against the side wall of the transmission rod, thereby fixing the locking point firmly.

[0045] Furthermore, the handle assembly 1 also includes a decorative cover 35, which covers the outer surface of the base 18 and has its edges flush with the surface of the window sash 5 profile.

[0046] In this embodiment, the decorative cover 35 is fixed to the edge slot of the base 18 by a pre-set buckle on the inner side, which not only completely covers the bolt connection marks between the base 18 and the window sash profile, but also effectively prevents dust, rainwater and other impurities from entering the interior of the base.

[0047] The working principle of this invention is: When the user rotates the handle body 16, the rotating shaft 17 drives the drive gear 20 to rotate. The drive gear 20, through meshing with the driven rack 21, drives the main drive rod 6 to move along the height direction of the window sash 5. The top of the main drive rod 6 transmits power to the first driven drive rod 7 through the first angler 10. The first driven drive rod 7 then drives the second driven drive rod 8 to move synchronously through the second angler 11, realizing the linkage of the main drive rod 6, the first driven drive rod 7, and the second driven drive rod 8. At this time, the main locking point 13 on the main drive rod 6, the first auxiliary locking point 14 on the first driven drive rod 7, and the second auxiliary locking point 15 on the second driven drive rod 8 are precisely engaged with the corresponding lock seats 12 on the window frame 26, forming a multi-point locking structure, which effectively improves the sealing performance of the miniature window. At the same time, each component is hidden inside the profile through the preset installation groove 4, which not only avoids the sealing components being exposed and affecting the aesthetics, but also reduces the wear and tear on the components caused by external factors, extending their service life. In addition, the limiting block 22 and the U-shaped elastic clamp 23 on the rotating shaft 17 cooperate to lock or open the handle body 16. When the handle body 16 is rotated to the locked or open position, the arc-shaped protrusion of the U-shaped elastic clamp 23 will be inserted into the arc-shaped groove of the limiting block 22 to achieve the positioning of the handle, prevent the handle from rotating randomly during use, and improve the stability of operation.
