Description

Technical Field

[0001] This invention relates to a lock and a frame structure having the lock, particularly a locking structure for a frame of a sliding door, window, or roller screen door or window. Prior Technology

[0002] Existing sliding doors or windows open and close by the lateral movement of a single door panel. For security reasons, when closed, the user must use a locking mechanism to prevent the sliding door or window from moving laterally, thus locking it. This prevents unauthorized entry and protects young children from leaving without the care and protection of elders. However, if the user forgets to lock it, an intruder can still enter. Furthermore, young children can easily open the sliding door or window to leave, increasing the risk of accidents or injuries due to human negligence.

[0003] In addition, existing screen doors or windows have a different structure. The screen mesh is rolled up on a roller at one end, and the other end of the screen mesh is attached to a side rod that can be pulled and can be approached from the side of a frame. Since this type of roller screen door or window structure lacks a locking component, the security risks of this type of roller screen door or window structure are more serious.

[0004] In view of this, the construction of conventional sliding doors, windows, or roller screen doors or windows still needs to be improved. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide a lock and a frame structure having the lock. The lock can be used on sliding doors, windows, or roller screen doors or windows, and can automatically lock when the door, window, or screen door or window is closed.

[0006] A further object of the present invention is to provide a lock and a frame structure having the lock, which can have a second locking function after the door, window or screen door or screen window is automatically locked when closed.

[0007] The directions or similar terms used throughout this invention, such as "front," "back," "left," "right," "top," "bottom," "inner," "outer," and "side," are primarily for reference to the directions in the accompanying drawings. These directions or similar terms are only used to assist in explaining and understanding the various embodiments of this invention and are not intended to limit the invention.

[0008] The use of the quantifiers "a" or "an" for the elements and components described throughout this invention is for convenience and to provide the general meaning of the scope of the invention; in this invention, it should be interpreted as including one or at least one, and the concept of a single also includes the case of a plural, unless it clearly means otherwise.

[0009] The terms "first," "second," ... and "Nth" used throughout this invention are primarily used to distinguish descriptions of different elements or features (such as elements, directions, or steps, etc.) and do not indicate the maximum or minimum number of such elements or features possessed by a corresponding subject or method, nor do they imply any order of precedence.

[0010] The terms "combination," "integration," or "assembly" used throughout this invention mainly include those that can be separated without damaging the components after connection, or those that make the components inseparable after connection. These are terms that those with ordinary knowledge in the art can choose based on the material of the components to be connected or the assembly requirements.

[0011] The term "outer frame" as used throughout this invention can refer to the outer frame of a door, window, screen door, or screen window; and the term "screen window" as used throughout this invention can also refer to a "screen door." This invention does not limit the scope of the invention, and this is something that those skilled in the art can understand.

[0012] The lock of the present invention comprises: a housing having a front panel and a housing tube, the front panel having an operating port communicating with the housing tube, the bottom of the housing tube having a first connecting portion, and the top of the housing tube having a second connecting portion; a drive plate having a front surface and a back surface, the front surface having a first protrusion and a second protrusion corresponding to the operating port, the back surface of the drive plate having a driving groove corresponding to a first notch in the housing tube, the bottom of the drive plate having a column rod, and a reset element sleeved on the column rod to ensure that the drive plate has a constant reset force; and a locking assembly comprising: a base plate having a through hole for a release button with a pressing portion protruding, the release button having at least one shoulder corresponding to a limiting hole in the base plate, and a back plate fixed to the back surface of the base plate. The plate has at least one elastic element between the front and back plates; and a linkage plate has a protrusion for engaging the drive groove of the drive plate. The linkage plate has an opening groove through which an extension of the base plate passes and moves. Each of the two side walls forming the opening groove has a guide groove and a positioning groove. The guide groove corresponds to the shoulder of the release button, allowing the linkage plate to move within a predetermined range along the guide groove and the positioning groove to be aligned with the shoulder so that it cannot move, thereby causing the pressing part of the release button to protrude from the surface of the base plate. The linkage plate has at least one latching member with a head having a larger radial dimension; and a locking plate with at least one locking hole having a large hole with a larger radial dimension and a small hole with a smaller radial dimension connected together, allowing the head of the latching member to enter through the large hole and move to the small hole.

[0013] The locking structure of the present invention includes: the lock described above; a side rod having a first frame hole and a second frame hole that are connected in communication, the shell tube of the housing being coupled to the first frame hole, one side of the side rod having an opening groove extending in the longitudinal direction, the protrusion of the linkage plate passing through the second frame hole and being engaged in the driving groove of the drive plate; and an outer frame, the latch plate being coupled to a side groove surface of the outer frame, the side rod being used to move away from or towards the side groove surface, the pressing portion of the release button abutting against the latch plate, causing the head of the latching member to enter through the large hole of the latch plate and move to the small hole portion, and the panel of the housing driving the head of the latching member to move from the small hole to the large hole portion of the latch plate.

[0014] Accordingly, the lock and frame structure of the present invention, having the drive plate and the locking assembly, such that when the lock is used on a sliding door, window, or roller screen door or window, when the user moves the side bar of the sliding door, window, or roller screen door or window closes to the side groove of the outer frame to form a closed position, the locking assembly can automatically lock to prevent the user from forgetting to lock, thus preventing thieves from illegally entering the room and preventing young children from opening and leaving on their own, thereby preventing accidents or injuries to young children due to human negligence.

[0015] The second connecting part is a connecting seat, which is inserted into the top of the shell tube, and a retainer of the connecting seat is pushed up by an elastic element. In this way, the retainer can be easily connected to the top of the first frame hole, or the retainer can be easily removed from the first frame hole.

[0016] The drive plate further includes a lock seat, which is engaged with a second notch in the housing tube. The lock seat has two opposing shaft holes for fixing a shaft to support the rotation of a rotating wheel. A portion of the rotating wheel's circumferential surface protrudes from a window in the panel. The rotating wheel has a locking hole for allowing the end of the rod to enter or exit. Thus, the design of the rotating wheel enables the lock to have a second locking function.

[0017] The lock of the present invention may further include a fixing base attached to the lock base. The fixing base has a countersunk hole, into which an elastic element and a ball are inserted. The elastic element pushes the ball, causing the ball to abut against the circumferential surface of the rotating wheel. In this way, by the elastic element pushing the ball, the ball can abut against the circumferential surface of the rotating wheel, so that the rotating wheel can stop at a fixed position after rotation.

[0018] The circumferential surface of the rotating wheel has a marking, which is displayed through the window of the panel. This allows the user to clearly understand whether the end of the lever can enter the keyhole to form an unlocked state or cannot enter the keyhole to form a locked state.

[0019] The first connecting part is attached to the bottom inner surface of the first frame hole, and the second connecting part is attached to the top of the first frame hole. In this way, the card holder can be securely attached to the first frame hole.

[0020] The substrate has a first side plate extending to both sides, and the connecting plate has a second side plate extending to both sides. The side surface of the side rod, which contacts the side groove surface of the outer frame, has an open groove. The open groove extends along the longitudinal direction of the side rod, and the radial dimension of the bottom of the open groove is larger than the radial dimension of the opening. The first side plate and the second side plate are fitted into the open groove. Thus, the substrate and the connecting plate can be fitted into the open groove of the side rod, preventing the substrate and the connecting plate from coming out of the groove.

[Figure 3] A diagram showing the screen in an open state according to a preferred embodiment of the present invention. [Figure 4] Cross-sectional view along line AA in Figure 2. [Figure 5] A diagram showing the mesh of a preferred embodiment of the present invention in a closed state. [Figure 6] The action scenario is shown in Figure 2. Implementation

[0022] To make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments of the present invention are described below in conjunction with the accompanying drawings; in addition, those symbols that are used in different drawings are considered to be the same and their descriptions will be omitted.

[0023] Please refer to Figures 1 and 2, which are a preferred embodiment of the present invention. The lock may include a housing 1, a drive plate 2, a locking assembly 3, and a latch plate 4. The housing 1, the drive plate 2, and the locking assembly 3 may be connected to a side rod 5 of a mesh screen. The drive plate 2 may drive the locking assembly 3 to open, unlock, and remain in a locked state. The latch plate 4 may be connected to an outer frame 6. The locking assembly 3 may contact the latch plate 4 to form a lock.

[0024] The housing 1 is composed of a panel 11 and a housing tube 12. The panel 11 has an operating port 13. The housing tube 12 can be located on the back of the panel 11. The housing tube 12 can be a hollow tube. The operating port 13 communicates with the housing tube 12. The cross-sectional shape of the housing tube 12 can be rectangular. The bottom of the housing tube 12 can be a first connecting part 14. The first connecting part 14 can be connected to the bottom of a first frame hole 51 of the side rod 5. The top of the housing tube 12 can be a second connecting part 15. The second connecting part 15 can be connected to the top of the first frame hole 51, so that the panel 11 and the operating port 13 can be presented on a surface of the side rod 5. In this embodiment, the second connecting part 15 can be a connecting seat 16, which is inserted into the top of the shell tube 12. A retainer 161 of the connecting seat 16 is pushed up by an elastic element 162, so that the retainer 161 can be connected to the top of the first frame hole 51, or the retainer 161 can press down on the elastic element 162, so that the retainer 161 can be separated from the top of the first frame hole 51, and the shell 1 can be taken out from the first frame hole 51.

[0025] The drive plate 2 is movable and can be inserted into the shell tube 12. The drive plate 2 has a surface 2a and a back surface 2b. The surface 2a has a first protrusion 21 and a second protrusion 22, which correspond to the operating port 13 of the shell tube 12, so that a user can press the first protrusion 21 or the second protrusion 22 through the operating port 13, thereby moving the drive plate 2 toward the first joint 14 or the second joint 15. The back surface 2b of the drive plate 2 has a driving groove 23, which corresponds to a first notch 17 of the shell tube 12. In this embodiment, the driving groove 23 is composed of two plates 24 protruding from the back surface 2b, which protrude from the first notch 17. Preferably, the bottom of the drive plate 2 has a column 25, on which a reset element 26 can be sleeved. One end of the reset element 26 can abut against the bottom of the drive plate 2, and the other end of the reset element 26 can abut against the bottom of the shell tube 12, so that the drive plate 2 always has an upward reset force.

[0026] Preferably, the drive plate 2 may also include a lock seat 27, which can be coupled to a second notch 18 of the housing tube 12. The lock seat 27 has two opposing shaft holes 271, which are used to fix a shaft 272 to support the rotation of a rotating wheel 28. A partial circumferential surface of the rotating wheel 28 may protrude from a window hole 19 of the panel 11. Preferably, the rotating wheel 28 may be formed like a gear, so that the circumferential surface of the rotating wheel 28 has a number of tooth grooves 282. The rotating wheel 28 also has a locking hole 281, and the end of the rod 25 may enter or exit the locking hole 281, so that the side rod 5 can be opened relative to the outer frame 6, or the side rod 5 cannot be locked relative to the outer frame 6 (details to follow). Preferably, one end of the reset element 26, which pushes the drive plate 2 with a constant upward reset force, may also be sleeved on the shaft 272.

[0027] More preferably, the lock may also include a fixing seat 29, which has a positioning hole 291 that is opposite to a positioning hole 273 of the lock seat 27. A positioning element 292 can be positioned in the two positioning holes 291 and 273, so that the fixing seat 29 is engaged with the lock seat 27. The fixing seat 29 has a countersunk hole 293 in which an elastic element 294 and a ball 295 can be placed. The elastic element 294 is used to push the ball 295 so that the ball 295 can abut against the circumferential surface of the rotating wheel 28, so that the rotating wheel 28 can stop at the positioning after rotation. Preferably, the circumferential surface of the rotating wheel 28 may have a mark 283, which is presented by the window 19 of the panel 11, so that the user can clearly understand whether the end of the rod 25 is aligned with the lock hole 281, so that the drive plate 2 can be pressed. That is, so that the user can clearly understand whether the end of the rod 25 can enter the lock hole 281 of the rotating wheel 28 to form an unlocked state; or whether the end of the rod 25 cannot enter the lock hole 281 of the rotating wheel 28, so that the drive plate 2 cannot be pressed to form a locked state.

[0028] The locking assembly 3 can be attached to one side of the side rod 5 by a positioning element 311 through a positioning hole 312 from a base plate 31. The base plate 31 has a through hole 313 for a pressing part 321 of a release button 32 to protrude from one surface, so that the pressing part 321 can protrude from the surface of the base plate 31. The release button 32 has at least one protruding shoulder 322, which can correspond to a limiting hole 314 of the base plate 31, so that the release button 32 will not come out from the through hole 313. In this embodiment, the release button 32 has a protruding shoulder 322 on each of two opposite sides, and the two shoulders 322 can respectively correspond to the two limiting holes 314 of the base plate 31. The substrate 31 has at least one positioning hole 315, and a positioning element 331 can be coupled to the at least one positioning hole 315 to fix a back plate 33 to the back side of the substrate 31, so as to ensure that the release button 32 can be restricted to actuation by the through hole 313. At least one elastic element 332 can also be provided between the back side of the release button 32 and the back plate 33. By pushing the elastic element 332, the pressing part 321 of the release button 32 always has a force that extends out of the through hole 313. Preferably, the substrate 31 has a first side plate 317 extending to both sides.

[0029] The locking assembly 3 also includes a linkage plate 34, which has a locking block 341 and a protrusion 342. The protrusion 342 can be engaged in the driving groove 23 of the drive plate 2, so that the drive plate 2 can be driven and move synchronously with the linkage plate 34. The locking block 341 can be integrally formed with the linkage plate 34, or as shown in the figure, the linkage plate 34 has a positioning hole 343, and a positioning element 344 can fix the locking block 341 to the linkage plate 34.

[0030] The linkage plate 34 has an opening groove 345, through which an extension 316 of the base plate 31 can move. Each of the two side walls of the opening groove 345 can have a guide groove 346 and a positioning groove 347. The guide groove 346 corresponds to the shoulder 322 of the release button 32, so that the linkage plate 34 can only move within a predetermined range according to the guide groove 346 and the release button 32. When the positioning groove 347 is aligned with the release button 32, the release button 32 is pushed by the elastic element 332, causing the shoulder 322 of the release button 32 to enter the positioning groove 347, so that the linkage plate 34 cannot move. At this time, the pressing part 321 of the release button 32 protrudes from the surface of the base plate 31 by a large amount. The linkage plate 34 has at least one fastener 348, which can be a conventional bolt with a head having a large radial dimension. In this embodiment, the linkage plate 34 has two fasteners 348, which are respectively adjacent to the upper and lower ends of the linkage plate 34. Preferably, the linkage plate 34 has a second side plate 349 extending to both sides. More preferably, the second side plate 349 has the same extension dimension and thickness as the first side plate 317 of the base plate 31.

[0031] The locking plate 4 provides a positioning element 41 for engaging with the side groove surface 61 of an outer frame 6. The locking plate 4 has at least one locking hole 42, which matches the latching member 348 on the linkage plate 34. The locking hole 42 has a larger radial hole and a smaller radial hole connected together, so that the head of the latching member 348 with a larger radial dimension can enter through the larger hole and move to the smaller hole, thereby forming a lock that prevents the side rod 5 from moving in the direction of separation (opening) relative to the side groove surface 61 of the outer frame 6.

[0032] Please refer to Figures 3 and 4, which illustrate an example of the lock of the present invention used in a roller blind screen. The rolling mechanism of the roller blind screen is a known component and is not a technical feature of the claims of the present invention, so it will not be described in detail. One end of the screen mesh of the screen has a side rod 5, which can be opened by moving away from or closed by moving towards the side groove surface 61 of the outer frame 6. The side rod 5 has a first frame hole 51 and a second frame hole 52. The first frame hole 51 and the second frame hole 52 are connected. The first frame hole 51 can face the indoor side of the roller blind screen, and the second frame hole 52 can face the side groove surface 61 of the outer frame 6 that can be contacted. Preferably, the side of the side rod 5 that can be contacted by the side groove surface 61 of the outer frame 6 has an open groove 53. The open groove 53 extends along the longitudinal direction of the side rod 5, and the radial dimension of the bottom of the open groove 53 is larger than the radial dimension of the opening, so that the first side plate 317 of the base plate 31 and the second side plate 349 of the linkage plate 34 can be fitted into the open groove 53, so that the base plate 31 and the linkage plate 34 will not come out of the opening.

[0033] The shell tube 12 of the housing 1 can be inserted into the first frame hole 51. The first connecting part 14 at the bottom of the shell tube 12 can be connected to the bottom inner surface of the first frame hole 51. The second connecting part 15 of the shell tube 12 can be connected to the top of the first frame hole 51. In this embodiment, the card seat 161 of the connecting seat 16 is pushed by the elastic element 162, so that the card seat 161 can be connected to the top inner surface of the first frame hole 51. The panel 11 of the housing 1 can cover the first frame hole 51. The first protrusion 21 and the second protrusion 22 of the drive plate 2 can correspond to the operation port 13, so that a user can press the first protrusion 21 or the second protrusion 22 through the operation port 13. The protrusion 342 of the linkage plate 34 passes through the second frame hole 52 and is locked in the driving groove 23 of the drive plate 2, so that the linkage plate 34 can be driven by the drive plate 2.

[0034] As shown in Figures 3 and 4, when the side rod 5 is about to leave the side groove surface 61 of the outer frame 6 to open the mesh, and the lock has the lock seat 27, the user first needs to rotate the wheel 28 so that the end of the rod 25 can enter the lock hole 281 of the wheel 28. The user can press the second protrusion 22 of the drive plate 2 to make the end of the rod 25 enter the lock hole 281 of the wheel 28 and compress the reset element 26. Since the protrusion 342 of the latch block 341 is stuck in the drive groove 23 of the drive plate 2, the drive plate 2 can simultaneously drive the linkage plate 34 to descend relative to the base plate 31, so that the latch 348 located on the linkage plate 34 can move from the small hole portion of the lock hole 42 to the large hole portion, so that the side rod 5 can leave the side groove surface 61 of the outer frame 6 to open. At this time, the positioning groove 347 of the linkage plate 34 is aligned with the pressing part 321 of the release button 32. Due to the push of the elastic element 332, the shoulder 322 of the release button 32 enters the positioning groove 347 of the linkage plate 34, and the pressing part 321 protrudes from the side of the side rod 5.

[0035] As shown in Figures 5 and 6, the side rod 5 contacts the side groove surface 61 of the outer frame 6 to form the closed state of the mesh. At this time, the pressing part 321 of the release button 32 protruding from the side of the side rod 5 collides with the locking plate 4, causing the release button 32 to retract and the elastic element 332 to be compressed, so that the shoulder 322 of the release button 32 leaves the positioning groove 347 of the linkage plate 34. At this time, the drive plate 2 is pushed by the reset element 26, causing the drive plate 2 to move upward and the linkage plate 34 to move upward synchronously via the locking block 341, and the guide groove 346 of the linkage plate 34 can... The shoulder 322 of the release button 32 is moved so that the latch 348 on the linkage plate 34 can move from the large hole of the lock hole 42 to the small hole, so that the side rod 5 is in a first locking state in which it cannot leave the side groove surface 61 of the outer frame 6. In addition, when the lock has the lock seat 27, the user can rotate the wheel 28 so that the lock hole 281 of the wheel 28 is misaligned with the end of the rod 25, so that the end of the rod 25 cannot enter the lock hole 281 of the wheel 28, thus forming a second locking state in which the side rod 5 cannot leave the outer frame 6.

[0036] In summary, the lock and frame structure of the present invention, having the drive plate and the locking assembly, allows for automatic first-level locking when used on sliding doors, windows, or roller screen doors or windows. This is achieved when the user moves the side bar of the sliding door, window, or roller screen door or window closes to the side groove of the outer frame to close it. This prevents the user from forgetting to lock the door, thus preventing unauthorized entry and children from opening the door and leaving, preventing accidents or injuries to children due to human negligence. Furthermore, the lock and frame structure of the present invention, through the design of the rotating wheel, provide a second-level locking function.

[0037] Although the present invention has been disclosed using the above preferred embodiments, it is not intended to limit the present invention. Any modifications and alterations made by those skilled in the art to the above embodiments without departing from the spirit and scope of the present invention shall still fall within the scope of the technology protected by the present invention.
