Description

Technical Field

[0001] This utility model belongs to the field of child protection products, specifically relating to a sliding door lock that can lock or protect sliding windows and sliding doors. Background Technology

[0002] Sliding windows and doors are commonly used in homes. They consist of two or more window or door panels, allowing the window or door to be opened or closed by the relative sliding movement of the two panels. Typically, locking mechanisms can be installed on each window panel to lock them in the closed position; this is the common structure for sliding windows. However, such locks can only lock the sliding window when it is closed, not while it is open for ventilation. Installing blocks along the sliding path of the window panels can limit the opening range of the corresponding panels, thus achieving both ventilation and preventing the sliding window from opening too wide. For example, some hotels use this method to limit the opening of sliding windows to prevent them from falling out. However, this can damage the window structure and makes opening the window complex when needed.

[0003] Chinese utility model patent CN208202901U discloses a novel sliding window and sliding door limiting device, which locks or unlocks the sliding window by flipping the limiting plate relative to the base plate; however, this device is relatively large. Chinese utility model patent CN218644074U discloses a sliding window safety lock, which locks the sliding window using a first locking member and a second locking member respectively installed on the side of one window sash and the surface of the other window sash; similarly, this lock is also large and consists of two parts, making installation relatively complex. Therefore, it is necessary to develop a completely new sliding door and sliding window lock. Summary of the Invention

[0004] The purpose of this utility model is to provide a sliding fan lock that is constructed with a single component to facilitate installation, has a small overall thickness to adapt to narrow gap installation, and has an aesthetically pleasing design.

[0005] As a first aspect of this utility model, a sliding fan lock is provided, comprising:

[0006] A first lock body, the first lock body including a first main body and an unlocking component movably disposed on the first main body;

[0007] A second lock body, hinged to the first lock body, with its pivot located on one side, pivots relative to the first lock body to switch between a first state for folding the sliding fan lock and a second state for locking the fan body's translation; and

[0008] A first locking mechanism acts between the unlocking member and the second lock body to lock at least the closing pivot of the second lock body in the second state. That is, the first locking mechanism can lock only the closing pivot of the second lock body without locking the opening pivot, or it can lock both the closing pivot and the opening pivot at the same time.

[0009] The unlocking component is either movable or rotatable along a linear path, where the linear path includes reciprocating along a straight line or curve, and the rotatable setting refers to being rotatable around its own center.

[0010] Preferably, the second lock body is provided with a lock cavity, and the unlocking member is provided with a lock tongue, which extends into or disengages from the lock cavity to lock or unlock, thus forming the first locking mechanism.

[0011] Preferably, one of the unlocking component and the second lock body has a first recess and the other has a first protrusion. The first recess and the first protrusion are misaligned or aligned to lock or unlock, thus forming the first locking mechanism.

[0012] Furthermore, the second lock body is provided with a first chamber, and in the first state, the unlocking element is at least partially accommodated in the first chamber.

[0013] Furthermore, the first body is provided with a boss and a second chamber, and the unlocking member is installed in the second chamber. In the first state, the boss is accommodated in the first chamber.

[0014] Preferably, the unlocking element is disposed along a path perpendicular to the pivot or a linear path parallel to the pivot, or is rotatably disposed in the second chamber.

[0015] Preferably, the first body and the unlocking component are respectively provided with a locking hole and a locking component. The locking hole is an elongated hole for the locking component to engage, so that the unlocking component can be moved and displaced along a straight path.

[0016] Preferably, when the locking tongue and the locking cavity constitute the first locking mechanism, the inner wall of the locking cavity is formed as a second abutment surface, and the outer side is left empty.

[0017] Preferably, the device further includes a second locking mechanism for locking or limiting the opening pivot of the second lock body in the second state. Wherein: locking means being able to stably maintain the lock, and limiting means being able to maintain the lock normally but being able to open it after applying a force exceeding a preset value, such as a limiting structure formed by the cooperation of protrusions and concave points in the prior art.

[0018] Furthermore, one of the first lock body and the second lock body is provided with a first shaft portion and the other is provided with a first shaft cavity. The first shaft portion is installed in the first shaft cavity and a first abutment portion is provided on one side of the first shaft cavity. In the second state, the first abutment surface of the first shaft portion abuts against the first abutment portion, thereby locking the opening pivot of the second lock body, thus forming a second locking mechanism.

[0019] Alternatively, one of the first lock body and the second lock body is provided with a limiting protrusion and the other is provided with a limiting groove. A third abutment is formed on the side wall of the limiting protrusion and a fourth abutment is formed on the bottom wall of the limiting groove. In the second state, the third abutment abuts against the fourth abutment, thereby locking the opening pivot of the second lock body, thus forming a second locking mechanism.

[0020] Preferably, a second limiting part is provided on one side of the first shaft cavity, and a first limiting part is correspondingly provided on the first lock body. When the second lock body is near the second state, the second limiting part abuts against the first limiting part and limits it.

[0021] Preferably, the lock cavity has two opposing second abutments, and in the second state, the lock tongue is inserted between the two second abutments.

[0022] Preferably, the first lock body and the second lock body are respectively provided with a first locking protrusion and a second locking protrusion.

[0023] Preferably, the second lock body includes a second main body and a buffer, wherein the buffer is made of a soft material.

[0024] The sliding fan lock of this utility model has the following advantages:

[0025] 1. The sliding window lock has a small thickness. The overall thickness is reduced by the misalignment of the first chamber and the unlocking component, making it suitable for use in scenarios where the gap between two sliding windows / doors is relatively small.

[0026] 2. The pivot is located on one side of the whole. After the first lock body is installed on one of the window sashes or door sashes, it can be turned open so that the second lock body can prevent the sliding movement of the other window sash or door sash. It is easy to operate, has a beautiful appearance, and does not affect the use of doors and windows when folded.

[0027] 3. By locking the second lock body in the second state in two directions through different locking mechanisms, the drawbacks of large volume or thickness that exist when using the same mechanism for locking can be avoided.

[0028] 4. By covering the second lock body entirely or partially with soft rubber, collision noise can be reduced and collision damage can be avoided; and by setting an elastic reset element, the unlocking element can be automatically locked.

[0029] 5. In the first state, the first limiting member can initially limit and hold the lock, preventing accidental opening of the sliding door lock. When it is necessary to open, the second lock body can be rotated by applying a force exceeding a predetermined strength without further unlocking. Conversely, rotation from the second state to the first state requires manual unlocking to prevent accidental closing of the sliding door lock. Attached Figure Description

[0052] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model will be described in detail below with reference to certain specific embodiments.

[0053] A sliding door lock, comprising:

[0054] The first lock body 10 includes a first main body 11 and an unlocking component 12, the unlocking component 12 being movably disposed on the first main body 11;

[0055] A second lock body 20, hinged to the first lock body 10, with a pivot 100 located on one side of the second lock body 20, pivots relative to the first lock body 10 to switch between a first state for folding the sliding fan lock and a second state for locking the fan body translation; and

[0056] A first locking mechanism 133 acts between the unlocking member 12 and the second lock body 20 to at least lock the closing pivot of the second lock body 20 in the second state.

[0057] The unlocking component 12 is configured to move along a linear path or be rotatable, for example, to move back and forth along a straight path, to move back and forth along a curved path, or to rotate around its own center.

[0058] Preferably, a second locking mechanism 130 may be included for locking or limiting the opening pivot of the second lock body 20 in the second state. The first locking mechanism 133 and the second locking mechanism 130 may be two separate components, or they may be the same component simultaneously locking bidirectional rotation.

[0059] Example 1

[0060] like Figure 1-6 As shown, a sliding door lock is a locking device used to open or close sliding windows, sliding doors, and other devices with two door / window sashes (i.e., sashes) by relative translational movement. The sliding door lock has the following features: Figure 1 The first state shown and as Figure 6 The second state is shown in the first state. In the first state, the second lock body 20 is close to the first lock body 10 and forms a folded state. At this time, the overall thickness is small, so it will not hinder the lateral opening of the sash (such as a window sash or door sash). The second lock body 20 rotates about 90° around the pivot 100 (the specific rotation angle can be set as needed) to form the second state and is held in this state. In the second state, the second lock body 20 is on the lateral opening path of the sash, thereby hindering the opening of the sash and achieving the purpose of locking the sash or limiting the maximum opening angle.

[0061] Whether the fan lock, after installation, locks or limits the opening of the fan depends on the installation position. When the installation position is close to the closed position of the fan, the fan lock is used to lock the fan open. When the fan lock is installed at a certain distance from the closed position to the open position, the fan can open a predetermined distance, thereby achieving the purpose of limiting the opening angle.

[0062] like Figure 1-2 As shown, the movable fan lock consists of a first lock body 10 and a second lock body 20. The first lock body 10 has a first shaft hole 223, and the second lock body 20 has a second shaft hole 216. A shaft member 102 (e.g., a shaft post or pin) passes through the two shaft holes, allowing the second lock body 20 to pivot relative to the first lock body 10, thus forming a pivot 100. Of course, in other embodiments, the shaft member 102 can also be made of... Figure 2 The single-piece shaft pin shown is replaced with two and installed separately from both sides.

[0063] Preferably, the pivot 100 is located on one side of the sliding door lock, and the bottom surface of the first lock body 10 is formed as a fixing surface 101 for fixing to the window sash or door sash.

[0064] like Figure 2-5 As shown, the first lock body 10 is composed of a first body 11 and an unlocking component 12. The first body 11 is pivotally connected to the second lock body 20, and the unlocking component 12 is movably disposed on the first body 11 and is used to lock or unlock the pivoting of the second lock body 20.

[0065] In this embodiment, the unlocking member 12 is movably positioned toward or away from the pivot 100, that is, its displacement path is along a direction perpendicular to the pivot 100, or in other words, along the front-back direction; specifically, the displacement movement of the unlocking member 12 is shown by the bidirectional arrow in 6.

[0066] A boss 111 is provided on the first lock body 10, and a second chamber 112 is provided inside the boss 111. The unlocking member 12 is movably disposed in the second chamber 112. The unlocking member 12 includes an unlocking body 121 that is generally flat and rectangular. A latch 122 is provided at the front end of the unlocking body 121. A locking member 123 is formed on both sides of the unlocking body 121, pointing downwards. A locking hole 115 is provided on the second chamber 112. The locking hole 115 is elongated, and its extension direction determines the displacement direction of the unlocking member 12. After assembly, the locking member 123 is inserted into the locking hole 115 to movably engage the unlocking member 12 with the first body 11. A first limiting surface 116 is provided on one side of the locking hole 115, and a second limiting surface 124 is provided on the locking member 123. The first and second limiting surfaces abut to engage.

[0067] A first shaft portion 221 is provided at both ends on one side of the first lock body 10. The two first shaft portions 221 are spaced apart to form a second shaft cavity 222 between them. A first shaft hole 223 is provided on the first shaft portion 221 for pivoting connection of the second lock body 20.

[0068] Furthermore, a reset seat 117 is provided on the bottom surface of the second chamber 112, and a reset member cavity 126 is provided on the bottom surface of the unlocking member 12. The reset member is installed between the reset seat 117 and the reset member cavity 126 so that the unlocking member 12 is initially held in the state where the locking tongue 122 is extended. The reset member is preferably a spring (not shown in the figure).

[0069] like Figure 5 As shown, a first chamber 202 and a first cavity wall 201 surrounding the first chamber 202 are formed on the bottom surface of the second lock body 20. By partially recessing the bottom surface of the second lock body 20, the first chamber 202 can be misaligned with the first lock body 10, thereby reducing the overall thickness of the sliding fan lock and avoiding excessive thickness that would result in poor applicability.

[0070] A second shaft portion 214 is provided at both ends on one side of the second lock body 20, and a third shaft portion 215 is provided between the two second shaft portions 214. The third shaft portion 215 and the second shaft portion 214 are spaced apart to form two first shaft cavities 218. The first shaft portion 221 of the first lock body 10 is installed in the first shaft cavity 218, and the second shaft portion 214 and the third shaft portion 215 are respectively provided with second shaft holes 216.

[0071] A first abutment 132 is provided on the outer side of the first shaft cavity 218, and a first abutment surface 131 is provided on the outer side of the first shaft portion 221. In the first state, the first abutment 132 abuts against the first abutment surface 131, preventing the second lock body 20 from continuing to rotate from the first state to the second state, thus limiting the opening angle of the second lock body 20. The first abutment 132 and the first abutment surface 131 constitute the second locking mechanism 130.

[0072] A locking cavity 217 is recessed on the outer side of the third shaft portion 215, and the locking cavity 217 occupies approximately half of the third shaft portion 215. A second abutment surface 220 is formed on one side of the locking cavity 217. The setting angle of the second abutment surface 220 is adapted to the opening angle of the second lock body 20. When the second lock body 20 is in the open second state, the bolt 122 is allowed to extend into the locking cavity 217, so that the side wall of the locking cavity 217 abuts against the second abutment surface 220, thereby preventing the second lock body 20 from rotating toward the first state, so that the bolt 122 and the locking cavity 217 form a first locking mechanism 133.

[0073] Furthermore, a second limiting portion 219 is provided on the inner side of the first shaft cavity 218, and the second limiting portion 219 is formed by a groove; at the same time, a first limiting portion 224 is provided on the first shaft portion 221, the first limiting portion 224 protrudes from the top of the first shaft portion 221, and a limiting surface is formed on the outer side of the first limiting portion 224, so that when the second lock body 20 is in the second open state, the limiting surface abuts against the groove inside the second limiting portion 219. The second limiting portion 219 and the first limiting portion 224 form a first limiting mechanism 134 near the second state.

[0074] Preferably, in order to prevent the second lock body 20 from generating noise or damaging the window sash or the sliding window lock due to collision when obstructing the window sash from closing, the second lock body 20 is composed of a second body 211 made of rigid material and a buffer 212 covering the second body 211. For example, the second body 211 is made of rigid plastic and the buffer 212 is made of soft rubber. In terms of process, they can be manufactured separately and then installed together, or the second body 211 made of rigid plastic can be placed in a mold and the buffer 212 can be formed by in-mold injection molding.

[0075] In this embodiment, an edge portion 113 is formed around the protrusion 111 of the first lock body 10 to allow the first and second lock bodies to be misaligned. Furthermore, to limit the pivoting of the second lock body 20 in the first state, a first locking protrusion 114 can be provided on the outer wall of the protrusion 111, and a corresponding second locking protrusion 213 can be provided on the side wall of the first chamber 202. These protrusions limit the movement but do not lock it; the user can apply a certain force to pivotally open the second lock body 20. Of course, a concave-convex structure can also be used to limit the movement of the second lock body 20. The first locking protrusion 114 and the second locking protrusion 213 constitute the second limiting mechanism.

[0076] like Figure 3 , 6 As shown, a contact portion 125 is also provided on the surface of the unlocking member 12 to facilitate the user's movement of the unlocking member 12. The contact portion 125 can be a groove, a protrusion, or other structure or material with greater friction.

[0077] The sliding fan lock of this embodiment has multiple usage states (or multiple installation methods):

[0078] Firstly, reference Figure 6 As shown, when the inner side of the second lock body 20 is facing the window sash to be locked, the second locking mechanism prevents the window sash from moving.

[0079] Secondly, the sliding window lock can also be installed in reverse, with the outer side of the second lock body 20 facing the window sash to be locked (see reference). Figure 6 As shown in the diagram, the first locking mechanism then prevents the window sash from moving.

[0080] Thirdly, the sliding window lock can also be installed with one of its left or right sides facing the window sash to be locked, so that the window sash can be slid and locked using one side of the second lock body 20. This is the recommended installation method.

[0081] The installation method of the sliding window lock in this embodiment is very convenient. The structure of a single component can be completed by applying 3M adhesive or similar glue to the fixed surface 101 and then installing it to a suitable position on the window sash (different from a movable window sash). It should be noted that the installation method of this sliding window lock is related to whether the second locking mechanism 130 and the first locking mechanism 133 are provided. That is, the second lock body 20 should have the function of preventing the window sash from sliding. The installation requirements can be explained to the user in the instruction manual.

[0082] Furthermore, although this embodiment provides a specific structure for locking / unlocking operations using an unlocking member 12 with a reciprocating displacement mechanism, the displacement path of the unlocking member 12 can also have a displacement component in a direction parallel to the pivot 100, in addition to being generally oriented towards the pivot 100 (i.e., perpendicular to the pivot 100), thus forming an oblique displacement toward or away from the pivot 100. Alternatively, the unlocking member 12 can be configured as a rotary structure, thereby enabling the latch 122 to extend into or disengage from the lock cavity 217 to achieve locking / unlocking through its rotation. Correspondingly, the left and right side walls of the lock cavity 217 should have a larger space relative to linear displacement to allow the latch 122 of the unlocking member 12 to rotate or rotate out within it.

[0083] Example 2

[0084] like Figure 8-11 As shown, a sliding fan lock has a similar main structure to Embodiment 1. The main difference is that the displacement direction of the unlocking component 12 and the specific structure of the first and second locking mechanisms are different in this embodiment.

[0085] refer to Figure 8-9 As shown, in this embodiment, the unlocking member 12 moves in the left-right direction, that is, it moves in a direction parallel to the pivot 100. (Refer to...) Figure 8 As shown by the double-headed arrow.

[0086] A first protrusion 142 is provided on the second lock body 20, and a first recess 141 is provided on the unlocking member 12 of the first lock body 10. When the first recess 141 moves to align with the first protrusion 142, if the second lock body 20 rotates around the pivot 100, the first protrusion 142 can move into the first recess 141, thereby allowing the second lock body 20 to rotate. Figure 9 , 10 As shown; conversely, when the two are misaligned, if the second lock body 20 rotates, it will cause the first protrusion 142 to interfere with the unlocking member 12, thereby hindering the rotation of the second lock body 20 (see...). Figure 8 As shown in the figure, this achieves the rotational locking of the second lock body 20. The first protrusion 142 and the first recess 141 form a first locking mechanism 133, which is used to lock the rotation of the second lock body 20 when needed, preventing the second lock body 20 from rotating from the second state to the first state.

[0087] like Figure 11 As shown, in this embodiment, the unlocking component 12 is still movably installed on the first body 11 by the means of the card component 123 being inserted into the card hole 115, only the extension direction of the card hole 115 is different from that in the first embodiment.

[0088] In addition, when the second lock body 20 rotates to a preset angle, that is, when it rotates to the angle of the second state, in addition to locking the rotation of the second lock body 20 toward the first state by the first locking mechanism 133, it is also necessary to lock the continued rotation of the second lock body 20.

[0089] To this end, a limiting groove 136 is provided on the third shaft portion 215, and a fourth abutment surface 138 is formed on the bottom wall of the limiting groove 136; correspondingly, a limiting protrusion 135 is protruding in the second shaft cavity 222, and a third abutment surface 137 is formed on the outer wall of the limiting protrusion 135. When the second lock body 20 rotates to the second state, the fourth abutment surface 138 abuts against the third abutment surface 137, thereby restricting the second lock body 20 from continuing to rotate. Furthermore, see... Figure 11 As shown, in this embodiment, the first abutment 132 is not provided on the outer side of the first shaft cavity 218 (of course, it is also feasible to retain the first abutment 132 in other embodiments). Therefore, the limiting protrusion 135 and the limiting groove 136 constitute the second locking mechanism 130.

[0090] In this embodiment, the fourth abutment surface 138 is arranged parallel to the fixed surface 101 (in the first state), and the third abutment surface 137 is arranged perpendicular to the fixed surface 101, so that the rotation angle of the second lock body 20 is 0-90°. If it is necessary to change the rotation angle of the second lock body 20, the angle between the fourth abutment surface 138 and the third abutment surface 137 can be changed accordingly.

[0091] Example 3

[0092] A sliding fan lock has the same main structure as Embodiment 1, but the main difference is that the displacement direction of the unlocking member 12 and the specific locking structure are different in this embodiment.

[0093] In this embodiment, both the second locking mechanism 130 and the first locking mechanism 133 are composed of a locking tongue 122 and a locking cavity 217. (See reference) Figure 5 As shown, the locking cavity 217 can be changed from being located on the outside of the third shaft portion 215 to being recessed in the middle of the third shaft portion 215, thereby forming abutment surfaces on both sides of the locking cavity 217. This allows the locking tongue 122 to abut against the two abutment surfaces on its two sides in the second state, preventing the second lock body 20 from opening or closing.

[0094] Compared with this embodiment, in embodiment one, the lock cavity 217 can be misaligned with the second shaft hole 216 provided in the third shaft portion 215, and the volume of the third shaft portion 215 is not too large, thereby reducing the thickness or volume of the fan lock in embodiment one.
