Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, in particular to a locking mechanism for a suspended window and a suspended window. Background Art

[0002] What is provided in this part is only background information related to the present application to facilitate those skilled in the art to understand the present application more thoroughly and accurately. It is not necessarily prior art.

[0003] The casement top-hung window system is a common window opening and closing mechanism in modern families. By turning the handle, the window can be opened and closed, and the window can be adjusted to three states: locked, casement, and top-hung, thus improving the convenience of window use.

[0004] When it is necessary to release the top-hung state of the window, it is necessary to push the window sash outwards with force by hand. However, the weight of the window sash is relatively large, which is difficult for pregnant women or children to operate. At the same time, since the window sash is in an outwardly suspended state, there are also certain safety hazards in continuing to push the window sash outwards. For this reason, some merchants have set up a new unlocking mechanism, and only by turning the handle can the top-hung locking state of the window sash be released, and then by pulling the handle, the window sash can be driven to close.

[0005] However, after the top-hung locking state of the window sash is released and the handle is pulled to drive the window sash to close completely, at this time the window sash is still in a free moving state, and the user can still continue to open the window sash to the top-hung state. As a result, a situation is likely to occur: when the window sash is in the top-hung open state, the user turns the handle and adjusts the window sash to the casement state, and at this time the window sash cannot be normally opened (i.e., in both the top-hung and outwardly open states), so it is necessary for the staff to carry out repairs, which is rather troublesome. Summary of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a locking mechanism for a suspended window and a suspended window, which can solve the problems mentioned in the above background art and avoid misoperation by users.

[0007] The technical solution adopted by the utility model to solve its problems is as follows:

[0008] A locking mechanism for a suspended window, comprising:

[0009] A transmission rod, which is used for driving connection with the handle; an active locking point is provided on the transmission rod;

[0010] A corner bracket, which is used for installation in the window sash profile; a first sliding groove is opened on the corner bracket, and the transmission rod is slidably arranged on the first sliding groove;

[0011] A fixed plate for installation inside a window frame profile; a lock catch is provided on the fixed plate and is adapted to cooperate with the movable locking point.

[0012] Wherein, when the handle is rotated to release the hanging and locking state of the window sash, and when the window sash is closed until it is completely received inside the window frame, the movable locking point abuts and clamps with the lock catch to lock the window sash.

[0013] Furthermore, a first inclined surface is provided on the movable locking point, and a second inclined surface adapted to cooperate with the first inclined surface is provided on the lock catch.

[0014] When the window sash is closed until the first inclined surface on the movable locking point abuts and cooperates with the second inclined surface on the lock catch, the lock catch drives the movable locking point to move. Until the window sash is completely received inside the window frame, the movable locking point resets and abuts and clamps with the lock catch to restrict the opening of the window sash.

[0015] Furthermore, the movable locking point includes a sliding plate slidably arranged on the transmission rod and an elastic member cooperating with the sliding plate. A first convex block is provided on the sliding plate, and the first inclined surface is provided on one side of the first convex block.

[0016] The lock catch includes a fixed seat arranged on the fixed plate. A second convex block is provided on the fixed seat, and the second inclined surface is provided on one side of the second convex block.

[0017] When the window sash is closed until the first inclined surface on the first convex block abuts and cooperates with the second inclined surface on the second convex block, the fixed seat drives the sliding plate to overcome the elastic force of the elastic member and move. Until the window sash is completely received inside the window frame, the elastic member releases the elastic force and drives the sliding plate to reset so that the first convex block abuts against the second convex block to restrict the opening of the window sash.

[0018] Furthermore, a second sliding groove is provided on the transmission rod, and the sliding plate is slidably arranged in the second sliding groove; the elastic member is a spring, and the spring is arranged in the second sliding groove and one end thereof abuts against the sliding plate, and the other end abuts against the inner wall of the second sliding groove.

[0019] Furthermore, a cover plate is provided on the transmission rod and is located at the second sliding groove, and the cover plate confines the spring in the second sliding groove.

[0020] Furthermore, an adjusting member is provided on the fixed plate and is used to adjust the position of the fixed seat, wherein:

[0021] The adjusting member is an eccentric nail, and the eccentric nail includes a main shaft and an eccentric shaft arranged at the bottom of the main shaft; a limiting hole and a third slide groove connected to the limiting hole are provided on the fixing plate, and the fixing seat is clamped in the third slide groove; the main shaft is passed through the fixing seat and the eccentric shaft is clamped in the limiting hole;

[0022] When the eccentric nail is rotated, the eccentric shaft can be driven to slide in the limiting hole, and the fixing seat can be driven to move in the third sliding groove through the main shaft to adjust its position.

[0023] Furthermore, the limiting hole is a waist-shaped hole and is arranged horizontally, and the third sliding groove is arranged vertically;

[0024] When the eccentric nail is rotated, the eccentric shaft can be driven to move left and right in the horizontal direction, and the fixing seat can be driven to move up and down in the vertical direction through the main shaft.

[0025] Furthermore, an adjustment hole for inserting an external tool is provided on the top surface of the main shaft.

[0026] Furthermore, it also includes a clamping structure arranged between the transmission rod and the fixing plate, wherein:

[0027] The clamping structure includes a clamping slot and a clamping block clamped with the clamping slot, one of the clamping slot and the clamping block is arranged on the transmission rod, and the other is arranged on the fixing plate;

[0028] When the handle is rotated to drive the transmission rod to move until the clamping block is engaged with the clamping groove, the window sash is in a locked state.

[0029] In addition, the utility model also provides a hanging window, including a window frame, a window sash and a locking mechanism for the hanging window.

[0030] In summary, the utility model provides a locking mechanism for a hanging window and a hanging window. When the hanging locking state of the window sash is released and the handle is pulled to drive the window sash to be completely closed, the movable locking point on the window sash abuts against the lock buckle on the window frame to lock and fix the window sash. At this time, the user cannot open the window sash. Then, after turning the handle and adjusting the window sash to a horizontally open state, the user can push the handle to drive the window sash to open horizontally normally. Therefore, by setting a locking mechanism, it is possible to prevent the user from turning the handle to switch the window sash to a horizontally open state when the window sash is in a hanging open state, thereby preventing the user from operating incorrectly, thereby ensuring the normal use of the hanging window, greatly improving its reliability in use, and extending its service life.

[0049] Embodiment 1

[0050] Refer to Figure 1-11 , the present invention first provides a locking mechanism 1 for a hanging window, including a transmission rod 11, a corner bracket 12 and a fixed plate 14. The transmission rod 11 is used for driving connection with a handle, the corner bracket 12 is used for installation in the profile of the window sash 2, and the fixed plate 14 is used for installation in the profile of the window frame 3; specifically, a first chute 121 is provided on the corner bracket 12, and the transmission rod 11 is slidably arranged on the first chute 121. When the handle is rotated, the transmission rod 11 can be driven to slide on the first chute 121.

[0051] Among them, an active locking point 13 is provided on the transmission rod 11, a first inclined surface 13111 is provided on the active locking point 13, a locking buckle 15 that cooperates with the active locking point 13 is provided on the fixed plate 14, and a second inclined surface 15111 that cooperates with the first inclined surface 13111 is provided on the locking buckle 15; when the handle is rotated to release the hanging and locking state of the window sash 2, the handle is pulled to drive the window sash 2 to close until the first inclined surface 13111 on the active locking point 13 abuts and cooperates with the second inclined surface 15111 on the locking buckle 15, the locking buckle 15 drives the active locking point 13 to move, until when the window sash 2 is completely received in the window frame 3, the active locking point 13 resets and abuts and clamps with the locking buckle 15 to limit the opening of the window sash 2 (as Figure 11 shown), thereby realizing the locking of the window sash 2.

[0052] Thus, by providing the locking mechanism 1, it is possible to prevent the user from rotating the handle to switch the window sash 2 to the casement state when the window sash 2 is in the hanging and open state, thereby avoiding misoperation by the user, further ensuring the normal use of the hanging window, greatly improving its use reliability, and extending its service life.

[0053] Refer to Figure 2-7 , the active locking point 13 includes a sliding plate 131 slidably arranged on the transmission rod 11 and an elastic member 132 that cooperates with the sliding plate 131, a first convex block 1311 is provided on the sliding plate 131, and the first inclined surface 13111 is provided on one side of the first convex block 1311; the locking buckle 15 includes a fixed seat 151 arranged on the fixed plate 14, a second convex block 1511 is provided on the fixed seat 151, and the second inclined surface 15111 is provided on one side of the second convex block 1511; when the window sash 2 is closed until the first inclined surface 13111 on the first convex block 1311 abuts and cooperates with the second inclined surface 15111 on the second convex block 1511, the fixed seat 151 drives the sliding plate 131 to overcome the elastic force of the elastic member 132 and move, until when the window sash 2 is completely received in the window frame 3, the elastic member 132 releases the elastic force and drives the sliding plate 131 to reset so that the first convex block 1311 abuts against the second convex block 1511 to limit the opening of the window sash 2.

[0054] In this embodiment, the second convex blocks 1511 are respectively arranged on both sides of the end face of the fixed seat 151, so as to realize universal left and right assembly, and greatly improve its applicability.

[0055] More specifically, a second sliding groove 111 and a positioning and locking hole 112 communicating with the second sliding groove 111 are formed in the transmission rod 11. The sliding plate 131 is slidably disposed in the second sliding groove 111 and a part of the first convex block 1311 is clamped in the positioning and locking hole 112. The second sliding groove 111 and the positioning and locking hole 112 can respectively guide the movement of the sliding plate 131 and the first convex block 1311. The elastic member 132 is a spring. The spring is disposed in the second sliding groove 111, one end of which abuts against the sliding plate 131 and the other end abuts against the inner wall of the second sliding groove 111. In addition, a cover plate 133 disposed on the transmission rod 11 and located at the second sliding groove 111 is further included. The cover plate 133 confines the spring in the second sliding groove 111.

[0056] More specifically, the latch 15 further includes an adjusting member disposed on the fixing plate 14 and used for adjusting the position of the fixing seat 151. Preferably, the adjusting member is an eccentric pin 152. The eccentric pin 152 includes a main shaft 1521 and an eccentric shaft 1522 disposed at the bottom of the main shaft 1521. A limiting hole 142 and a third sliding groove 143 communicating with the limiting hole 142 are formed in the fixing plate 14. A part of the fixing seat 151 is clamped in the third sliding groove 143. The main shaft 1521 passes through the fixing seat 151 and the eccentric shaft 1522 is clamped in the limiting hole 142. Thus, when the eccentric pin 152 is rotated, the eccentric shaft 1522 can be driven to slide in the limiting hole 142, and the fixing seat 151 can be driven by the main shaft 1521 to move in the third sliding groove 143 to adjust its position.

[0057] Preferably, the limiting hole 142 is a kidney-shaped hole and is horizontally arranged. The third sliding groove 143 is vertically arranged. When the eccentric pin 152 is rotated, the eccentric shaft 1522 can be driven to move left and right in the horizontal direction, and the fixing seat 151 can be driven by the main shaft 1521 to move up and down in the vertical direction, so as to adjust its position.

[0058] Thus, by setting the adjusting member to adjust the position of the fixing seat 151, the correct positional relationship between it and the movable locking point 13 can be ensured, thereby avoiding interference between the two due to assembly errors or the like, and further ensuring that the suspended window can be normally opened and closed.

[0059] In this embodiment, an installation hole 1512 through which the main shaft 1521 can pass and be fixed is formed in the fixing seat 151.

[0060] In addition, an adjusting hole 15211 into which an external tool can be inserted is further formed on the top surface of the main shaft 1521, so as to facilitate the user to adjust the position of the fixing seat 151. Preferably, the adjusting hole 15211 is a hexagonal groove hole.

[0061] Refer to again Figure 1-11The locking mechanism 1 further comprises a clamping structure arranged between the transmission rod 11 and the fixing plate 14, wherein the clamping structure comprises a clamping slot 113 and a clamping block 141 clamped with the clamping slot 113, the clamping slot 113 is arranged on the transmission rod 11, and the clamping block 141 is arranged on the fixing plate 14; when the handle is rotated to drive the transmission rod 11 to move until the clamping block 141 is clamped with the clamping slot 113, the window sash 2 is in a locked state. Figure 8 shown.

[0062] Of course, in other embodiments, the positions of the card block 141 and the card slot 113 may be swapped, which can also achieve the same technical effect, and is not limited here.

[0063] Embodiment 2

[0064] See also Figure 12-13 The utility model also provides a hanging window, including a window frame 3, a window sash 2 and the locking mechanism 1 for the hanging window of the above-mentioned embodiment 1. In this embodiment, the hanging window is a top-hung outward-opening window. The window sash 2 can be adjusted to a top-hung open state, a top-hung unlocked state, an outward-opening state and a locked state by turning the handle.

[0065] Among them, the corner turner bracket 12 in the locking mechanism 1 is installed at the bottom corner of the window sash 2, and the fixing plate 14 in the locking mechanism 1 is also installed at the bottom corner of the window frame 3 and corresponds to the corner turner bracket 12; the transmission rod 11 is slidably disposed on the corner turner bracket 12 and is located on the side of the window sash 2.

[0066] Therefore, when the handle is turned to release the upper hanging locking state of the window sash 2 and the handle is pulled to drive the window sash 2 to be completely closed, the movable locking point 13 on the window sash 2 abuts and clamps with the lock buckle 15 on the window frame 3 to achieve the locking and fixation of the window sash 2. At this time, the user cannot open the window sash 2. Subsequently, by turning the handle and adjusting the window sash 2 to a state where it can be opened outwards, the user can push the handle to drive the window sash 2 to be opened outwards.

[0067] In summary, the utility model provides a locking mechanism 1 for a hanging window and a hanging window. When the hanging locking state of the window sash 2 is released and the handle is pulled to drive the window sash 2 to be completely closed, the movable locking point 13 on the window sash 2 is abutted and clamped with the lock buckle 15 on the window frame 3 to achieve locking and fixing of the window sash 2. At this time, the user cannot open the window sash 2. Then, after turning the handle and adjusting the window sash 2 to a horizontally open state, the user can push the handle to drive the window sash 2 to open normally. Therefore, by setting a locking mechanism, it is possible to avoid the user turning the handle to switch the window sash 2 to a horizontally open state when the window sash 2 is in an upper hanging state, thereby avoiding the user's misoperation, thereby ensuring the normal use of the hanging window, greatly improving its reliability in use, and extending its service life.

[0068] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0069] It should be understood that the orientation or positional relationship indicated by terms such as "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred module or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0070] In addition, in the description of the present invention, the meanings of "a plurality of" and "several" are two or more, unless otherwise specifically defined.

[0071] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
