Description

Technical Field

[0001] This invention relates to the technical field of door and window structures, and more specifically, to a child lock for windows and doors / windows. Background Technology

[0002] Accidents involving children falling or getting stuck after climbing out of windows occur frequently because many family windows can only be opened as casement windows and do not include gap ventilation. Even if a window has gap ventilation, it does not have a child lock switch. Many window components with gap ventilation require modification of the window frame for installation, which can affect the window's airtightness, sound insulation, and heat insulation.

[0003] Currently, child locks can generally only be installed below the opening sash of doors and windows. After the opening sash is partially opened, it can be fully opened by manual operation. However, because the child lock is located below the window sash and is easy to operate, there is a high probability that it will be accidentally opened by a child, thus losing the original function of the child lock. As a result, some hardware manufacturers dare not call their products child locks in order to avoid disputes, and instead call them micro ventilators. Summary of the Invention

[0004] Therefore, to address the problem that existing child locks are usually located at the bottom of doors and windows, allowing for easy opening of the window sash with a simple operation, making them susceptible to accidental operation by children and thus failing to provide full protection, this invention provides a child lock for windows and doors, the specific technical solution of which is as follows:

[0005] A child lock for windows, installed on doors and windows, includes a limiting groove frame, a mounting base, a swing rod, a limiting rod, and a locking unit. The limiting groove frame is installed on the window frame and has a limiting space. The mounting base is installed on the window sash and has a sliding space. The swing rod has a first limiting end and a sliding end, the first limiting end being disposed within the limiting space, and the sliding end being disposed within the sliding space via a locking structure. The limiting rod has a second limiting end and a locking end, the second limiting end being connected to the sliding end and disposed within the sliding space. The locking unit is used to switch the limiting rod between a first state, a second state, or a third state.

[0006] In the first state, the locking end is fixedly connected, and the window sash is fixed relative to the window frame;

[0007] In the second state, the locking end is movable, the sliding end is able to slide in the sliding space, and is able to rotate at the left end of the sliding space;

[0008] In the third state, the locking end and the sliding end move to the right end of the sliding space, and the first limiting end can move out of the limiting space.

[0009] The aforementioned child lock for windows can be installed at any position on the opening sash of a door or window by setting the limiting groove frame and mounting base in different locations according to specific circumstances, thus preventing accidental operation by children; at the same time, the window sash can only be fully opened by using the locking unit in conjunction with the movement of the window sash, thus providing a protective function.

[0010] Furthermore, the locking structure includes a sliding track disposed within the sliding space, a rotation position disposed on the left side of the sliding track, a sliding head disposed at the sliding end, and a rotation arc disposed at the sliding head.

[0011] Furthermore, the sliding head is a round head with a parallel limiting surface; the sliding track is provided with a parallel track adapted to the parallel limiting surface.

[0012] Furthermore, the locking unit includes a handle and a locking element that is tractively connected to the handle; when the handle is vertically positioned, the locking element presses against the window sash, and the window sash cannot be opened; when the handle is horizontally positioned to the left, the locking element releases the window sash, and the window sash can be opened; when the handle is horizontally positioned to the right, the locking element releases the window sash and presses against the sliding end, moving it to the right end of the sliding space.

[0013] Furthermore, the sliding space is a cavity with a rectangular cross-section, and the second limiting end and the sliding end are hinged by a pin.

[0014] Furthermore, the end of the limiting groove frame away from the mounting base is provided with a groove opening that communicates with the limiting space.

[0015] Furthermore, the sliding end includes a sliding shaft disposed on the swing rod; the sliding shaft has a groove in the middle and a limiting shoulder at the end; the sliding space is adapted to the limiting shoulder and has a locking baffle on the side facing the swing rod, the locking baffle forming a sliding groove adapted to the groove.

[0016] Furthermore, the swing rod and the limiting rod are made of aluminum alloy plate, stainless steel plate or galvanized steel plate.

[0017] On the other hand, a door and window includes a window frame, a window sash, and a child lock for the window; the limiting groove frame is disposed on the window frame, and the mounting base is disposed on the window sash.

[0018] Furthermore, the mounting base is disposed at the top of the window sash. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of protection of the invention.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] In this invention, the terms "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0038] On the one hand, such as Figure 1 and Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a child lock for windows in one embodiment of the present invention is installed on doors and windows, including a limiting groove frame 1, a mounting base 2, a swing rod 3, a limiting rod 4, and a locking unit 5; the limiting groove frame 1 is installed on the window frame and has a limiting space 101; the mounting base 2 is installed on the window sash and has a sliding space 201; the swing rod 3 has a first limiting end 31 and a sliding end 32, the first limiting end 31 is disposed in the limiting space 101, and the sliding end 32 is disposed in the sliding space 201 through a locking structure 6; the limiting rod 4 has a second limiting end 41 and a locking end 42, the second limiting end 41 is connected to the sliding end 32 and is disposed in the sliding space 201; the locking unit 5 is used to switch the first state, second state, or third state of the limiting rod 4;

[0039] In the first state, the locking end 42 is fixedly connected, and the window sash is fixed relative to the window frame;

[0040] In the second state, the locking end 42 can move, and the sliding end 32 can slide in the sliding space 201 and rotate at the left end of the sliding space 201.

[0041] In the third state, the locking end 42 and the sliding end 32 move to the right end of the sliding space 201, and the first limiting end 31 can move out of the limiting space 101.

[0042] The aforementioned child lock for windows can be installed at any position on the opening sash of a door or window by setting the limiting groove frame 1 and the mounting base 2 in different positions according to specific circumstances, thus preventing accidental operation by children; at the same time, the window sash can only be fully opened by using the locking unit 5 in conjunction with the movement of the window sash, thus playing a protective role.

[0043] In one embodiment, the locking structure 6 includes a sliding track 61 disposed within the sliding space 201, a rotation position 62 disposed on the left side of the sliding track 61, a sliding head 63 disposed on the sliding end 32, and a rotation arc 64 disposed on the sliding head 63. Thus, due to the limiting effect of the sliding track 61, the sliding head 63 can only slide within the sliding track 61, and can only rotate after reaching the rotation position 62 on the left side of the sliding track 61 and utilizing the rotation arc 64, further preventing accidental operation by children and improving safe use.

[0044] In one embodiment, the sliding head 63 is a round head with a parallel limiting surface; the sliding track 61 is provided with a parallel track adapted to the parallel limiting surface. Thus, the round head structure with the parallel limiting surface is simple and has low processing cost.

[0045] In one embodiment, the locking unit 5 includes a handle 51 and a locking member throttledly connected to the handle 51. When the handle 51 is vertically positioned, the locking member presses against the window sash, preventing the window from opening. When the handle 51 is horizontally positioned to the left, the locking member releases the window sash, allowing it to open. Furthermore, the sliding end 32 can slide within the sliding space 201 and rotate at the left end of the sliding space 201. When the handle 51 is horizontally positioned to the right, the locking member releases the window sash and presses against the sliding end 32, moving it to the right end of the sliding space 201, allowing the first limiting end 31 to move out of the limiting space 101. Thus, by positioning the handle 51 in a position easily accessible to adult users, ease of use is further improved.

[0046] In one embodiment, the sliding space 201 is a rectangular cavity, and the second limiting end 41 and the sliding end 32 are hinged by a pin. Thus, by using a pin to rotatably connect the second limiting end 41 and the sliding end 32, it is ensured that the swing rod 3 and the limiting rod 4 can rotate relative to each other while maintaining close contact during movement.

[0047] In one embodiment, the end of the limiting groove frame 1 away from the mounting base 2 is provided with a disengagement opening 102 that communicates with the limiting space 101. Thus, by providing the disengagement opening 102, the first limiting end 31 can be disengaged from the limiting space 101, thereby allowing the window sash to be fully opened relative to the window frame.

[0048] In one embodiment, the sliding end 32 includes a sliding shaft disposed on the swing rod 3; the sliding shaft has a groove in the middle and a limiting shoulder at its end; the sliding space 201 is adapted to the limiting shoulder and has a retaining baffle on the side facing the swing rod 3, the retaining baffle forming a sliding groove adapted to the groove. Thus, the sliding groove formed by the retaining baffle restricts the groove in the middle of the sliding shaft, preventing the sliding shaft from disengaging from the sliding space 201 in the vertical direction.

[0049] In one embodiment, the swing rod 3 and the limiting rod 4 are made of aluminum alloy plate, stainless steel plate or galvanized steel plate. Specifically, they are made of stainless steel plate.

[0050] On the other hand, such as Figure 1 and Figure 2 , Figure 6 As shown, a door and window according to one embodiment of the present invention includes a window frame 7, a window sash 8, and a child lock 9 for the window; the limiting groove frame 1 is disposed on the window frame 7, and the mounting base 2 is disposed on the window sash 8.

[0051] In one embodiment, the mounting base 2 is disposed on the top of the window sash 8.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
