Description

Technical Field

[0001] This utility model belongs to the technical field of door and window hardware accessories, specifically relating to handle mechanisms, locks and door and window systems. Background Technology

[0002] Chinese Patent Publication No. CN119664183A discloses a sliding door locking structure and door mechanism. The door mechanism includes an upper track, a door body, a handle, and a sliding door locking structure. The locking structure includes a lock box, a vertical frame, and a locking rod. The lock box is located on the upper track, the handle is located on the door body, and the vertical frame is located on the vertical side wall of the door body. The locking rod and the handle are connected by a transmission mechanism. One end of the locking rod has a latch. Driven by the handle, the locking rod can move up and down to engage or disengage the latch into the lock groove of the lock box. This door mechanism positions the lock box and lock groove on the upper side of the door body, thus removing them from the user's view and improving the aesthetics of the door and window system. The handle has a transmission plate, and the locking rod... Connected to the transmission plate and moving up and down synchronously with it, the transmission plate needs to be fastened to the vertical edge of the vertical frame to ensure that it can move in a direction perpendicular to the horizontal plane and thus drive the locking rod to move in the same direction. The fastening connection between the transmission plate and the vertical frame guides the transmission plate to move in a direction perpendicular to the horizontal plane. However, since the vertical frame is made of profiles, there are certain deviations in its dimensions during the production process. If the vertical frame is too thick, it will be difficult for the transmission plate to fasten to the edge of the vertical frame. If the vertical frame is too thin, even if the transmission plate is fastened to the edge of the vertical frame, the transmission plate is prone to tilting or shaking during the movement and will not be able to drive the locking rod to move in a direction perpendicular to the horizontal plane.

[0024] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0025] Please see Figures 1 to 6This application provides a handle mechanism 1 for a lock, which includes a lock box and a lock rod 2. The lock box is used to be mounted on an upper or lower track, and the lock rod 2 can move up and down between a locked position and an unlocked position. When the lock rod 2 is in the locked position, the lock rod 2 extends into the lock box. The handle mechanism 1 includes a mounting panel 11, a connecting block 12, and a transmission plate 13. The mounting panel 11 is fixed to the vertical frame 4, providing a mounting base and support for the entire handle mechanism 1. The connecting block 12 is located on the mounting panel 11 and can rotate relative to the mounting panel 11 between a first position and a second position. In the first position, the width of the connecting block 12 is smaller than the width of the groove of the vertical frame connecting groove 41, allowing the connecting block 12 to smoothly enter the vertical frame connecting groove 41. In the second position, the connecting block 12 is used to abut against the vertical frame connecting groove 41, thereby fixing the mounting panel 11 to the vertical frame 4. The transmission plate 13 is slidably connected to the mounting panel 11. The transmission plate 13 is used to connect the locking rod 2, and a guide limit is formed between the transmission plate 13 and the mounting panel 11 to guide the transmission plate 13 to slide vertically relative to the mounting panel 11.

[0026] The handle mechanism 1 provided in this application embodiment has two aspects. First, by using a connecting block 12 that is rotatable relative to the mounting panel 11, the mounting panel 11 is fixed to the vertical frame connecting groove 41. This eliminates the need for additional holes in the vertical frame connecting groove 41, allowing the handle mechanism 1 to be installed on a conventional vertical frame 4, greatly improving its versatility and reducing installation costs and difficulties. Second, by using a guide limiter between the transmission plate 13 and the mounting panel 11 to guide the transmission plate 13 to move in a direction perpendicular to the horizontal plane, the adaptation problem of the transmission plate 13 caused by the dimensional deviation of the vertical frame 4 is avoided. This ensures that the transmission plate 13 can stably drive the locking rod 2 to move accurately up and down between the locked and unlocked positions, allowing the locking rod 2 to accurately insert into or disengage from the lock box during movement. This effectively realizes the locking and unlocking functions of the door and window system, improving the stability and reliability of the lock operation.

[0027] like Figures 3 to 6As shown, in one embodiment, the handle mechanism 1 further includes a first fastener 14, which is rotatably mounted on the mounting panel 11 and screwed to the connecting block 12. Rotating the first fastener 14 can drive the connecting block 12 to rotate to a second position. At this position, the two limiting walls 121 of the connecting block 12 abut against the two side walls of the vertical frame connecting groove 41, preventing the connecting block 12 from rotating within the vertical frame connecting groove 41. Furthermore, the first fastener 14 cannot move axially. Continuing to rotate the first fastener 14 can thread-drive the connecting block 12 so that the mounting panel 11 and the connecting block 12 are respectively clamped and fixed to both sides of the vertical frame connecting groove 41. Thus, firstly, the installer only needs to rotate the first fastener 14 to sequentially complete the positioning and locking of the connecting block 12 and the clamping and fixing of the mounting panel 11 and the connecting block 12 to the vertical frame connecting groove 41. Compared to traditional complex installation methods, no additional positioning tools or complex adjustment steps are required, greatly simplifying the installation process, improving installation efficiency, and reducing installation difficulty and labor costs. Secondly, since the first fastener 14 is clamped and fixed by the threaded drive connecting block 12, the number of turns of the first fastener 14 can be flexibly adjusted according to the actual thickness of the vertical frame 4, thereby changing the distance between the mounting panel 11 and the connecting block 12, so that the handle mechanism 1 can adapt to vertical frames 4 of different thicknesses. This adaptability means that the handle mechanism 1 does not need to be specially designed and manufactured for vertical frames 4 of different specifications, which greatly improves its versatility.

[0028] like Figure 3 and Figure 5 As shown, in one embodiment, two connecting blocks 12 are provided, with the two connecting blocks 12 distributed vertically on the mounting panel 11. It should be noted that in some other embodiments, the number of connecting blocks 12 may also be, but is not limited to, one or three, etc., depending on the actual needs.

[0029] like Figure 3 and Figure 5As shown, in one embodiment, the mounting panel 11 is provided with a baffle 15, which is located above and / or below the connecting block 12. When the connecting block 12 is rotated in a first direction, the baffle 15 allows the connecting block 12 to rotate from the first position to the second position. When the connecting block 12 is rotated in a second direction, the baffle 15 blocks the connecting block 12 so that the connecting block 12 is always close to the first position, thereby making the width of the connecting block 12 smaller than the width of the vertical frame connecting groove 41, so that the connecting block 12 can smoothly enter the vertical frame connecting groove 41. The first direction and the second direction are opposite. In this way, this design provides clear operation guidance for the installer. When installing the handle mechanism 1 onto the vertical frame 4, it is only necessary to rotate the connecting block 12 in the predetermined first direction to ensure that the connecting block 12 accurately reaches the appropriate installation position, avoiding the problems of installation difficulties or incomplete installation caused by blind rotation or incorrect rotation direction, and greatly improving the accuracy and efficiency of installation. Furthermore, the baffle 15 restricts the different rotation directions of the connecting block 12, enabling installation and maintenance personnel to clearly identify the correct operating direction when disassembling or adjusting the handle mechanism 1. They can simply rotate the connecting block 12 in the first direction opposite to that during installation to return it from the second position to the first position, facilitating disassembly or maintenance operations. This clear directional indication reduces the possibility of operational errors and improves the efficiency and accuracy of maintenance work.

[0030] like Figure 3 and Figure 5 As shown, in one embodiment, the length direction of the baffle 15 is inclined to the horizontal plane.

[0031] It is understandable that if the first direction is clockwise, then the second direction is counterclockwise; if the first direction is counterclockwise, then the second direction is clockwise.

[0032] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, the mounting panel 11 includes a main body 111, a first guide block 112, and a second guide block 113. The first guide block 112 and the second guide block 113 are respectively disposed on the upper and lower sides of the main body 111. The transmission plate 13 has a sliding cavity 131, a first guide groove 132, and a second guide groove 133, all extending vertically. The first guide groove 132 and the second guide groove 133 are respectively disposed on the upper and lower sides of the sliding cavity 131. The main body 111 and the sliding cavity 131 are slidably connected. When the transmission plate 13 is in the highest position relative to the mounting panel 11, the first guide block 112 and the first guide groove 132 are slidably connected. When the transmission plate 13 is in the lowest position relative to the mounting panel 11, the second guide block 113 and the second guide groove 133 are slidably connected. Thus, by setting the first guide block 112 and the second guide block 113 on the upper and lower sides of the main body 111 on the mounting panel 11, and correspondingly opening the first guide groove 132 and the second guide groove 133 on the upper and lower sides of the sliding cavity 131 on the transmission plate 13, at least one set of guide blocks and guide grooves is always in a sliding state of engagement, regardless of the position of the transmission plate 13 during its up-and-down movement relative to the mounting panel 11. For example, when the transmission plate 13 moves in the middle position, the first guide block 112 and the first guide groove 132, and the second guide block 113 and the second guide groove 133 work together; when the transmission plate 13 moves to near the highest position, the first guide block 112 and the first guide groove 132 work closely together to provide the main guidance, and even if the engagement of the second guide block 113 and the second guide groove 133 gradually weakens, it can be ensured that the transmission plate 13 will not have a significant deviation; similarly, when the transmission plate 13 moves to near the lowest position, the second guide block 113 and the second guide groove 133 play a leading role. This design greatly improves the stability of the movement of the transmission plate 13, avoiding problems such as tilting and shaking of the transmission plate 13 caused by the failure of a single guide structure at a specific position. The stable guide structure ensures that the transmission plate 13 can move strictly in the first direction perpendicular to the horizontal plane, allowing the locking rod 2 connected to the transmission plate 13 to switch precisely between the locked and unlocked positions.

[0033] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, the transmission plate 13 is provided with a transmission arm 134, and the handle mechanism 1 also includes a handle seat 16 and a lever arm 17. The handle seat 16 is used to fix to the vertical frame 4 or the door leaf body 111. The handle seat 16 is provided with a slide groove 161 extending in the vertical direction. The lever arm 17 is slidably disposed in the slide groove 161, and the lever arm 17 and the transmission arm 134 are connected in a transmission manner. In this way, the power generated by the handle operation can be accurately and directly transmitted to the transmission arm 134 through the lever arm 17, thereby driving the transmission plate 13 to move. Since the slide groove 161 strictly limits the movement direction of the lever arm 17, it ensures the accuracy of the direction during power transmission, reduces energy loss during transmission, greatly improves the transmission efficiency, and enables the handle operation to be converted into the opening or closing action of the lock more quickly and effectively.

[0034] In one embodiment, the handle base 16 is typically fixed to the vertical frame 4 or the door leaf body 111 using common methods such as screw fastening, making the installation process relatively simple. Specifically, in this embodiment, the handle base 16 is provided with a second fastener 162, which passes through the vertical frame 4 and the handle base 16 to fix the handle base 16 to the vertical frame 4.

[0035] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the transmission arm 134 is provided with a transmission groove 135, and the actuating arm 17 is inserted into the transmission groove 135. Thus, when installing the handle mechanism 1, the transmission plate 13 can be directly connected to the actuating arm 17 through the transmission groove 135 to complete the initial positioning of the mounting panel 11. This operation eliminates the need for the steps of precise measurement and adjustment using complex tools in the traditional installation method, and the installer does not need to spend a lot of time finding a suitable installation position and angle.

[0036] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, two transmission arms 134 and two toggle arms 17 are provided. The two toggle arms 17 are connected to the two transmission arms 134 in a one-to-one correspondence, and the two toggle arms 17 are located on both sides of the door body 111 in the thickness direction. The handle mechanism 1 also includes a toggle button 18, which is detachably connected to one of the toggle arms 17. In this way, the toggle button 18 connected to one of the toggle arms 17 serves as the normal switch, while the toggle arm 17 without the toggle button 18 serves as an emergency switch. This clear functional distinction allows users to quickly select the appropriate operation method according to different usage scenarios and needs. In daily use, users can conveniently perform regular switching operations using the toggle button 18 to meet the needs of frequent use; while in emergency situations, such as when the normal switch fails or when the lock needs to be opened quickly, the toggle arm 17 without the toggle button 18 can play its role as an emergency switch in a timely manner, ensuring that the lock can be opened normally, thus improving the functionality and practicality of the handle mechanism 1 and its ability to deal with emergencies.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the two actuating arms 17 are a first actuating arm 171 and a second actuating arm 172, respectively. A toggle button 18 is detachably connected to the first actuating arm 171. The handle mechanism 1 also includes a cover 19, which covers the slide groove 161 where the second actuating arm 172 is located, and conceals the second actuating arm 172. Thus, the cover 19 hides the second actuating arm 172, making the handle mechanism 1 appear simpler and neater. Furthermore, the cover 19 provides a certain degree of protection, preventing dust, moisture, and debris from entering the slide groove 161, thus preventing these external factors from corroding and damaging the second actuating arm 172 and its transmission components. In addition, in emergency operation, the user can quickly locate and open the cover 19 in an emergency to operate the second actuating arm 172 to unlock the lock, ensuring the clarity and timeliness of emergency operations.

[0038] In one embodiment, the handle mechanism further includes an elastic element (not shown in the figure), which is disposed between the main body 111 and the sliding cavity 131. The elastic element is used to elastically drive the transmission plate 13 to move to the highest or lowest position, so as to ensure that the transmission plate 13 moves into place. In this way, the elastic element, by virtue of its preset elasticity characteristics, can provide a stable and predictable driving force for the transmission plate 13. During the operation of the handle mechanism, it can ensure that the transmission plate 13 moves precisely to the highest or lowest position according to the design requirements.

[0039] like Figures 1 to 4As shown, this application embodiment also provides a lock, including a handle mechanism 1 as described in any of the above embodiments, and also includes a lock box (not shown) and a lock rod 2. The lock box is used to be mounted on an upper track (not shown) or a lower track (not shown). The lock rod 2 is connected to a transmission plate 13 for transmission. Under the drive of the transmission plate 13, the lock rod 2 moves up and down between the unlocked position and the locked position.

[0040] In one embodiment, the lock also includes a latch 3, which is disposed at the end of the locking bar 2. The latch 3 moves up and down with the locking bar 2 to engage or disengage with the lock box.

[0041] like Figures 1 to 4 As shown, in addition, this application embodiment also provides a door and window system, including a lock as described in any of the above embodiments, and also includes a track, a vertical frame 4 and a door leaf body 111. The door leaf body 111 is slidably mounted on the track, the vertical frame 4 is connected to the door leaf body 111, and the vertical frame 4 is provided with a vertical frame connecting groove 41.

[0042] In summary, the handle mechanism 1, lock, and door / window system disclosed in this utility model can bring at least the following beneficial technical effects: (1) The mounting panel 11 is fixed to the vertical frame connecting groove 41 by using the connecting block 12 that is rotatable relative to the mounting panel 11. No additional holes need to be made in the vertical frame connecting groove 41, so that the handle mechanism 1 can be installed on the conventional vertical frame 4, which greatly improves its versatility and reduces the installation cost and difficulty. (2) The transmission plate 13 is guided to move in a direction perpendicular to the horizontal plane by the guide limit between the transmission plate 13 and the mounting panel 11, which avoids the adaptation problem of the transmission plate 13 caused by the size deviation of the vertical frame 4, and ensures that the transmission plate 13 can stably drive the locking rod 2 to move up and down accurately between the locked position and the unlocked position. (3) The installer can complete the positioning and locking of the connecting block 12 and the clamping and fixing of the mounting panel 11 and the connecting block 12 to the vertical frame connecting groove 41 by simply rotating the first fastener 14. No additional positioning tools or complicated adjustment steps are required, which greatly simplifies the installation process, improves the installation efficiency, and reduces the installation difficulty and labor cost. (4) Since the first fastener 14 is clamped and fixed by the threaded drive connecting block 12, the number of turns of the first fastener 14 can be flexibly adjusted according to the actual thickness of the vertical frame 4, thereby changing the distance between the mounting panel 11 and the connecting block 12, so that the handle mechanism 1 can adapt to vertical frames 4 of different thicknesses.

[0043] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
