Description

Technical Field

[0001] This invention relates to the field of door and window hardware, and more particularly to a window opener with a child lock mechanism. Background Technology

[0002] Casement windows in high-rise residential buildings are typically equipped with window openers to limit the opening angle and prevent falls caused by excessive opening. However, in some situations, it is necessary to fully open the casement window. To meet this need, some window openers have a function switching capability, allowing for both micro-ventilation at a smaller opening angle and removal of the angle restriction. To prevent children from falling, some window openers also incorporate child locks. For example, Chinese patent CN222066470U discloses a push-button child lock limiter for doors and windows; however, its child lock operation is inconvenient, and it requires manual locking, posing a safety hazard if the user forgets to deactivate it. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a window opener with a child lock mechanism that can limit the opening angle of the window sash and enable quick switching.

[0004] To achieve the above objectives, the technical solution adopted by this invention is as follows: A window opener with a child lock mechanism includes a first component and a second component respectively mounted on a frame and a sash. The first component includes a first fixed base fixedly mounted on a base surface, a slider that slides with the first fixed base in the X-axis direction, and a child lock mechanism for locking the slider. The second component includes a sliding point. The first fixed base has a first groove, and the slider has a second groove. Both the first and second grooves extend along the X-axis and their open ends are aligned. When the slider slides along the X-axis to a first endpoint, the first and second grooves together form a closed slide for the sliding point to slide through. When the slider slides along the X-axis to a second endpoint, the first and second grooves separate, leaving an open opening between their open ends for the sliding point to pass through.

[0005] The beneficial effects of this invention are as follows: When the slider slides to the first endpoint, its first and second slide grooves together form a closed slide, and the sliding point on the second component can only slide within the closed slide, thereby limiting the opening angle of the fan body and preventing the risk of falling due to an excessively large opening angle of the fan body 4. When the slider slides to the second endpoint, the first and second slide grooves separate from each other, and the sliding point on the second component can pass through the opening between them, thus leaving the first and second slide grooves. At this time, the fan body can open freely without being restricted by the first and second slide grooves. The child lock mechanism in this invention locks the slider. When it is necessary to switch the slider between the first and second endpoints on the X-axis, the child lock mechanism needs to be unlocked to realize its safety function.

[0006] Preferably, the child lock mechanism includes a rotating locking block rotatably connected to the slider and a locking part disposed on the first fixed base. A baffle is formed on the back of the rotating locking block. When the rotating locking block is rotated to the unlocking position, the baffle avoids the locking part; when the rotating locking block is rotated to the locking position, the baffle and the locking part cooperate to lock in the X-axis direction. With the above structure, the child lock mechanism can be quickly unlocked or unlocked by rotating the rotating locking block, making operation simple.

[0007] Preferably, the rotating locking block or slider has a marking on its front side to indicate the locking position. This marking allows the user to quickly ascertain the status of the child lock mechanism, preventing erroneous operation.

[0008] Preferably, the second component further includes a second fixed seat and a connecting rod. The two ends of the connecting rod are hinged to the second fixed seat and the sliding point, respectively. The second fixed seat is slidably fitted to the base surface along the X-axis. The second fixed seat also has a pushing part for pushing the slider. When the sliding point slides within the closed slide, the swing amplitude of the connecting rod is limited by the stroke of the sliding point within the closed slide, thereby limiting the opening angle of the fan body and achieving a safety anti-fall function.

[0009] Preferably, the first fixing seat includes a fixing seat body and a fixing seat body with a first sliding groove. Using the fixing seat body to form the first sliding groove avoids direct wear of the fixing seat body by the sliding point, and the use of plastic material for the fixing seat body reduces weight and cost. At the same time, the first sliding groove has a certain thickness to achieve a good guiding effect.

[0010] Preferably, the inner wall of the first groove is formed with elastic protrusions. The elastic protrusions can limit the sliding point to a certain extent, so that it can remain within the position range defined by the elastic protrusions when no external force is applied. At the same time, the change in resistance when the sliding point passes through the elastic protrusions can also allow the user to perceive the change in the position of the sliding point within the first groove.

[0011] Preferably, a positioning bead and a positioning groove are provided between the slider and the first fixed seat. The positioning bead and the positioning groove ensure that the slider will not slide accidentally when there is no external force in the unlocked state.

[0012] Preferably, a rotating plate is rotatably connected to the back of the first fixing base. The rotating plate enables quick connection of the first component to the fan body or frame, further improving installation efficiency. At the same time, the rotating plate also increases the number of connection points between the first fixing base and the base surface, making safety more reliable.

[0013] Preferably, the first fixed base has baffles formed on both sides to guide the slider to slide along the X-axis, and the slider has limit bars to restrict the slider from sliding out of the baffles. This structure allows the slider to slide relative to the first fixed base along the X-axis while preventing it from detaching.

[0014] Preferably, the opposite sides of the first fixed base and the slider are formed with guide ramps for guiding the sliding point into the first or second slide groove. When the fan body is closed again in the unlocked state of the child lock system, the guide ramps can be used to smoothly slide the sliding point from the opening between the first or second slide groove into the first or second slide groove.

Detailed Implementation

[0025] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] See Figures 1 to 6 As shown, the window opener of the present invention includes a first component 1 and a second component 2 respectively mounted on a frame 5 and a sash 4. In this embodiment, the first component 1 is mounted on the frame 5, and the second component 2 is mounted on the sash 4. In other embodiments, the mounting positions of the first component 1 and the second component 2 can be adjusted according to actual conditions.

[0028] The first component 1 includes a first fixed base 11 fixedly mounted on the base surface, a slider 12 that slides with the first fixed base 11 in the X-axis direction, and a child lock mechanism for locking the slider 12. In this embodiment, the first component 1 is mounted on the side frame strip of the frame 5. The X-axis direction is parallel to the length direction (i.e., the height direction) of the side frame strip, and the rotation axis of the fan body 4 is parallel to the X-axis direction. The first fixed base 11 has baffles 113 formed on both sides to guide the slider 12 to slide along the X-axis direction. The slider 12 has limit bars 122 formed to restrict the slider 12 from sliding out of the baffles 113.

[0029] The first fixed base 11 has a first sliding groove 111, and the slider 12 has a second sliding groove 121. The first sliding groove 111 and the second sliding groove 121 both extend along the X-axis and their open ends are aligned with each other. When the slider 12 slides along the X-axis to the first end point, the first sliding groove 111 and the second sliding groove 121 together form a closed slide for the sliding point 23 to slide. When the slider 12 slides along the X-axis to the second end point, the first sliding groove 111 and the second sliding groove 121 separate from each other and leave an open opening between their open ends for the sliding point 23 to pass through. In this embodiment, the open opening is perpendicular to the X-axis direction. When the fan body 4 is opened, the sliding point 23 can pass through the open opening and slide out of the first component 1. The opposite sides of the first fixed base 11 and the slider 12 are formed with guide slopes 16 for guiding the sliding point 23 to slide into the first sliding groove 111 or the second sliding groove 121.

[0030] The child lock mechanism includes a rotating locking block 131 rotatably connected to the slider 12 and a locking part 132 disposed on the first fixed base 11. A baffle 133 is formed on the back of the rotating locking block 131. In this embodiment, there are two baffles 133 arranged in a C-shape, with an opening between the two baffles 133 for the locking part 132 to pass through. The locking part 132 is a protrusion protruding from the first fixed base 11. When the rotating locking block 131 is rotated to the unlock position, the opening between the two baffles 133 is aligned with the locking part 132 in the X-axis direction, allowing the baffles 133 to avoid the locking part 132, and the slider 12 can slide freely in the X-axis direction. When the rotating locking block 131 is rotated to the locking position, the baffles 133 and the locking part 132 are aligned in the X-axis direction, and the slider 12 is unable to slide in the X-axis direction due to the locking effect of the baffles 133 and the locking part 132. In order to enable users to quickly know the current gear position of the rotating lock block 131, in this embodiment, a mark for indicating the gear position is provided on the front of the slider 12, and a slot is also provided on the front of the rotating lock block 131, which can be used as an indicator mark or to be turned with a tool.

[0031] The first fixed base 11 includes a fixed base body 11a and a fixed base body 11b. The fixed base body 11b has a first sliding groove 111, and an elastic protrusion 112 is formed on the inner wall of the first sliding groove 111. The formation of the first sliding groove 111 in the fixed base body 11b prevents the sliding point 23 from directly wearing down the fixed base body 11a. Furthermore, the plastic material used in the fixed base body 11b reduces weight and cost, while the thickness of the first sliding groove 111 provides good guidance. The elastic protrusion 112 can limit the sliding point 23 to a certain extent, keeping it within the position range defined by the elastic protrusion 112 without external force. Simultaneously, the change in resistance when the sliding point 23 passes through the elastic protrusion 112 allows the user to perceive the positional change of the sliding point 23 within the first sliding groove 111. A positioning bead 14 and a positioning groove are provided between the slider 12 and the first fixed base 11. The positioning glass bead 14 and the positioning groove can prevent the slider 12 from sliding unexpectedly when it is in the unlocked state and there is no external force.

[0032] The first fixing base 11 has a rotating plate 15 rotatably connected to its back. The rotating plate 15 can be used to realize the quick connection of the first component 1 to the fan body 4 or the frame 5, further improving the installation efficiency. At the same time, the rotating plate 15 can also increase the connection points between the first fixing base 11 and the base surface, making the safety more reliable.

[0033] The second component 2 includes a sliding point 23, a second fixed seat 21, and a connecting rod 22. The two ends of the connecting rod 22 are hinged to the second fixed seat 21 and the sliding point 23, respectively. The second fixed seat 21 slides along the X-axis with the base surface. The second fixed seat 21 also has a pushing part 211 for pushing the slider 12. In this embodiment, the second fixed seat 21 is mounted on the fan body 4 and linked to the handle 3. By operating the handle 3, the first fixed seat 11 can be moved along the X-axis.

[0034] The window opener is used in the following way in this embodiment: See Figure 7 and Figure 8 As shown, when micro-ventilation is required, the slider 12 is held at the first end position, and the locking block 131 is rotated to the locking position to prevent the slider 12 from moving. At this time, the first slide groove 111 and the second slide groove 121 together form a closed slide, and the sliding point 23 on the second component 2 can only slide within the closed slide, thereby limiting the opening angle of the fan body 4 and realizing the micro-ventilation function.

[0035] See Figure 9As shown, when the window sash needs to be opened freely, first switch the rotating lock block 131 to the unlock position. At this time, the slider 12 can slide freely in the X-axis direction without restriction. The user can rotate the handle 3 or push the window sash directly to make the sliding point 23 move the slider 12 to the second end point. At this time, the first slide groove 111 and the second slide groove 121 separate from each other and form an opening between them. When the window sash is opened further, the sliding point 23 on the second component 2 can pass through the opening between them and leave the first component 1. At this time, the sash 4 can be opened freely without being restricted by the first slide groove 111 and the second slide groove 121.

[0036] When the window is closed, the sliding point 23 returns to the first component 1 through the opening. At this time, by operating the handle 3, the second fixing seat 21 can be slid, thereby causing its pushing part 211 to retract the slider 12 to the first end point. Even if the child lock system is in the unlocked state at this time, the window must still be switched to the micro-ventilation state before opening the window again to ensure safety.

[0037] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make more possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, all equivalent changes made based on the concept of the present invention without departing from the scope of the present invention should be covered within the protection scope of the present invention.
