Description

Technical Field

[0001] This disclosure relates generally to door locks, and more particularly to child locks that can be retrofitted into doors in residences or other buildings. Background Technology

[0002] In recent years, with increasing awareness of child safety in the home environment, the development and innovation of child safety devices have become increasingly important. Among these devices, locks designed for doors represent a crucial aspect of preventing accidents and ensuring the safety of young children, pets, and the elderly. Traditional child locks often have limitations in terms of adaptability and effectiveness, which can impair their practicality in different residential environments. This invention attempts to address these shortcomings by introducing a variety of universal, safe, and easy-to-install locking mechanisms. These innovative designs are described through various illustrations demonstrating the functionality and adaptability of these locking mechanisms. Attached Figure Description

[0018] Figure 15 This is a schematic diagram illustrating an exemplary method for installing a lock on a door, based on the principles described herein. Detailed Implementation

[0019] Referring now to the figures, the same structures will have the same reference numerals. In the following description, numerous specific details are set forth for purposes of explanation in order to provide a thorough understanding of the system and method. However, it will be apparent, however, that the system and method can be practiced without these specific details. It is understood that the figures are illustrative and schematic representations of some embodiments of the invention and are not intended to limit the invention, nor are they necessarily drawn to scale. References to “example” or similar language in the specification mean that a particular feature, structure, or characteristic described in connection with the example is included in at least one example, but not necessarily in the others.

[0020] Furthermore, a feature illustrated and / or described may be combined with other features illustrated and / or described. As used in this specification and the appended claims, the term "majority" or similar language is intended to be understood broadly to include any positive number from 1 to infinity; zero is not a quantity, but rather a lack thereof.

[0021] Figure 1AA lock (100) is illustrated. In this example, the lock (100) is secured around a door (102) and latched behind a door side post (104) connected to a door frame (106). This prevents the door (102) from being opened by a child. In this example, the lock (100) includes a latching mechanism (111) and a release mechanism (113) connected by a U-shaped bracket (112). The latching mechanism (111) includes a latch body (108) and a latch (110). In this example, the release mechanism (113) includes at least one instance of a release body (114) and a screw (116).

[0022] The latch (110) retracts and extends from the latch body (108). When extending from the latch body (108), as shown in Figure 1, the latch (110) extends across the door side post / stop (104). This prevents the door (102) from opening as long as the latch (110) remains extended from the latch body (108). The latch body (108) is adapted to receive the latch (110) and may also include one or more mechanisms to retract the latch (110). A U-shaped bracket (112) connects the latch body (108) and the release body (114) by extending between the door (102) and the door frame (106). The release body (114) is used to release the lock (100) to open the door (102). In this example, a screw (116) is threaded through the release body (114) and pressed against the door (102). This secures the lock (100) to the door (102). Figure 1A The two sides of the door (102) are also indicated. The side of the door that includes the latch (110) and the doorposts (104) is referred to as the "latch side" or "doorpost side," as shown below. Figure 1A As shown, the opposite sides of the door are labeled "door release side". The door is considered "closed" when the leading surface (226) of the door passes the edge (228) of the door frame. In other words, the door is "closed" when at least a portion of the edge of the door is opposite the door frame and the door frame gap (105) has been at least partially formed. The door is considered "fully closed" when a standard latch on the door controlled by the door handle engages with the strike lock or other feature of the door frame and secures the door in the closed position.

[0023] This lock, and other examples shown herein, can offer numerous benefits. These benefits may include, but are not limited to: ease of installation; no damage to the door; allowing the door to be fully closed when the lock is engaged; and allowing an adult (or someone with sufficient reach) to open the lock from either side of the door. In some examples, the lock does not require any alterations to the door or door frame to function fully. This means that there are no screws, no adhesive tape that could potentially remove paint, and no holes or other damage to the door when installing the lock. However, if additional means are required to securely install the lock, some damage to the door may occur. The lock may also be able to be freely positioned along the perimeter of the door, along the vertical edges of the door, and at the top of the door. In some examples, locks may be available for use along the bottom of the door or on the hinged side of the door.

[0024] Figure 1B A cross-sectional view of an exemplary example of a lock (100) is shown, illustrating a band (118) attached to each side of the lock (100). The lock (100) in this example includes a latch (110), a latch body (108), a U-shaped bracket (112), a release body (114), a screw (116), and a band (118) that attaches to the latch (110), passes around the latch body (108), through the U-shaped bracket (112), and descends to the release body (114). The band (118) attached to both ends of the lock (100) serves as a communication channel or connection within the lock (100) mechanism. In this example, the band (118) mechanically transmits the position of a release slider (130) within the release body (114) to the latch (110) sliding within the latch mechanism (111). For this purpose, the strip (118) is mechanically attached to the release slider (130) and is tensioned when the release slider (130) is manually moved away from the screw (116). This tension causes the strip (118) to slide along the U-shaped bracket (112) and around internal features of the latch body (108) that redirect the tension on the strip (118) to retract the latch (110) into the latch body (108). These internal features may include guide surfaces (126). The strip (118) is attached to the latch (110) at the strip attachment (124). The latch (110) can be manually retracted from the latch side of the door in one of several ways.

[0025] In this example, the latch body (108) includes an access opening (122) that exposes finger holes (128) in the latch (110). A user can insert a finger through the access opening (122) and engage it with the finger hole (128) to slide the latch (110) away from the door frame (106) and door side post (104), thereby disengaging the latch (110) from the door frame (106) / door side post (104). This movement can be countered by one or more springs that tend to force the latch (110) to extend. Additionally or alternatively, the user can interact directly with the latch (110) to push it back into the latch body (108). For example, the user can press a curved instance or portion of the latch's ramp (115) to disengage it from the door side post (104).

[0026] Similarly, the latch (110) of the lock (100) can disengage from the release side of the door. On the release side, the user can insert their fingers or thumb through the access opening (122) and place them into the finger holes (128) of the release slider (130). The user then moves the release slider (130) away from the screw (116), thereby pulling / tensioning the band (118) and causing it to slide backward together with the release slider (130). The tensioned band (118) slides along its length and pulls the latch (110) into its retracted position.

[0027] The attachment of the lock (100) to the door (102) can be achieved in a variety of ways, including methods that do not require tools or damage the door (102). However, in some designs and situations, it may be desirable to use tools, fasteners, and / or adhesives to attach the lock (100) to the door (102) more securely. The use of tools, fasteners, adhesives, or other attachment strategies can allow for reduced design complexity and reduced strength requirements for various components. Figure 1B In the exemplary design shown, the lock (100) can be attached to and detached from the door (102) by turning the screw (116) in a clockwise or counterclockwise direction without damaging the door (102).

[0028] Figure 1CA top view of an exemplary latch mechanism (111) of the lock (100) is shown. The latch mechanism (111) includes a latch (110), a latch body (108), a strip (118), a latch slide (120), an access opening (122), a strip attachment (124), a guide surface (126), and a finger hole (128). The latch (110) is attached to the strip (118) within the latch body (108) to ensure that the latch can be opened from both sides of the door (102). The strip (118) is positioned on the guide surface (126) attached to the other side of the lock (100). As discussed above, the latch slide (120) within the access opening (122) is also visible on the top of the latch body (108) to allow the user to place their finger in the finger hole (128) and pull the latch (110) to open the door (102). Figure 1A ).

[0029] Figure 1D The lock (100, is shown) Figure 1A A bottom view of the release mechanism (113) of the door (102). The release mechanism (113) includes a release body (114), a screw (116), a release opening (144), a finger hole (128), a release slider (130), and a band (118). The release body (114) is securely held in place by the screw (116) to tighten around the door (102). Figure 1A The release opening (144) is located within the release body (114) to access the release slider (130) connected to the strip (118). As discussed above, the user's finger can be placed in the finger hole (128) and the release slider (130) pulled to open the door (102) from the other side. Figure 1A ).

[0030] Figure 1E , Figure 1F and Figure 1G These are different perspective views of the lock (100) and illustrate various aspects of this exemplary design. As discussed above, this embodiment of the lock (100) includes a release mechanism (113) with a release body (114) and two screws (116). A U-shaped bracket (112) connects the release mechanism (113) to a latching mechanism (111). The latching mechanism (111) includes a latch body (108), an access opening (122), and a latch (110). The latch (110) includes a ramp (115). The ramp (115) is designed to engage with the door frame (106, Figure 1A ) and door side pillars (104, Figure 1A ) Joining. As the ramp (115) slides over the door frame (106, Figure 1A ) and door side pillars (104, Figure 1AThe ramp forces the latch (110) to retract, thus allowing the door (102, Figure 1A The door closes by swinging. When the latch (110) reaches the door side post (104), Figure 1A When there is space behind it, it can automatically extend to meet the door side pillar (104, Figure 1A The back surface of the door (102) is joined together and the door (102) is joined together. Figure 1A Lock it in the appropriate position. Figure 1F Two openings (e.g., a tab (117) and an additional opening (121)) are also shown, allowing a strip (118) to pass through the latch body (108) and the release body (114), respectively. The latch edge (119) of the latch (110) is also shown. The latch edge (119) of the latch (110) can be used with the door side post (104, Figure 1A ) engagement, and can be particularly used for clamping door side post profiles with low surface area and / or inclined surfaces (see, for example) Figures 13A to 13E ).

[0031] Figure 1G An exemplary embodiment of a lock (100) is shown, illustrating a latch (110) including a retaining pad (123) forming a contact surface of the latch (110). In some embodiments, the retaining pad (123) may extend to the latch edge (119) of the latch (110). The retaining pad (123) may be made of any of a variety of materials and may be attached to the latch (110) in a variety of ways. For example, the retaining pad (123) may be made of rubber, silicone, plastic, metal, or other suitable materials and have any number of surface textures. The retaining pad (123) may be adhered to the latch (110), molded into the latch (110), mechanically attached to the latch (110), or attached using any other suitable technique. A ramp (115) of the latch (110) is also shown.

[0032] Figures 2A to 2I Various views of an example of a lock (100) are shown. Figure 2A A side view of the lock (100) is shown. Figure 2B The front view is shown. Figure 2C and Figure 2D These are the top view and the bottom view, respectively. Figure 2E This is the rear view of the lock, and Figure 2F and Figure 2G It is a perspective view. Figure 2H and Figure 2I This is a cross-sectional view of the locking mechanism (111), showing its internal structure.

[0033] These figures illustrate a locking mechanism (111) connected to a release mechanism (113) by a U-shaped bracket (112). In this example, the locking mechanism (111) includes a latch (110), a latch body (108), and a latch locking element (132). The release mechanism (113) includes a release body (114), a release slide (130) with an integral finger-shaped post extending through a side of the release body (114), and a spring ramp (136).

[0034] In this example, the U-shaped bracket (112) includes a groove (142) and a plurality of cables or strips (118) that form a communication connection between the latch and the release slider.

[0035] In at least one embodiment, the latch body (108) may include a latch locking member (132) on that side. The latch locking member (132) can be used to lock the latch (110) in place so as not to engage the door side post (104). Figure 1A However, this is only one exemplary embodiment. The latch locking element (132) can have a variety of different constructions and designs. For example, the latch can be implemented as a button instead of a slider. The button can be located in a variety of locations and surfaces. In one embodiment, the button can be located on the top surface of the latch body and can be used to engage and disengage both the latch locking element and the other component.

[0036] There are various constructions that can apply forces that tend to force the latch to extend. Figure 2H In this configuration, a tension spring (138) is attached over a post on the latch body (108) and to a post on the latch (110). Therefore, when the latch (110) is forced back into the latch body (108), the tension spring (138) extends and tends to return the latch (110) to the extended position. Figure 2H The image also shows a latch locking element (132) and a notch (180) or recess, which the latch locking element (132) can engage with the notch (180) or recess to lock the latch (110) in the retracted position.

[0037] Figure 2I The tension spring (138) is shown. Figure 2HAn alternative embodiment is provided, in which a compression spring (140) is used instead. In this example, a portion of the compression spring (140) is contained within the latch (110), and the opposite ends are supported by the latch body (108). When the latch (110) is pushed back into the latch body (108), the compression spring (140) compresses and tends to force the latch (110) out of the latch body (108). As discussed with respect to other figures, this spring-loaded latch design allows the latch to retract as the door is closing, and the latch's ramp engages with the door or doorpost. However, once the movement passes the doorpost, the latch automatically extends and engages with the doorpost, thus preventing the door from opening until the latch retracts. The latch can retract in several ways. For the user on the latch side of the door, a method such as... Figures 1A to 1G The shown finger holes allow the latch to be manually pushed backward, or pushed directly backward by pressing the manual ramp. From the other side, pressing the finger pins to move the release slider backward disengages the latch, applying tension to the strip and causing it to retract.

[0038] Figure 2I Also shown is a strip (118) and / or cable that bypasses the internal structure in the latch body (108) and is fastened / attached to the latch (110) such that when the strip (118) / cable (206, figure) is tightened, the latch (110) tends to retract, thereby allowing the door to be opened.

[0039] Figures 3A to 3F Various partial and cross-sectional views of the lock (100) are shown to illustrate exemplary internal components. Figure 3A The body without the locking mechanism (108) is shown. Figure 1A It also has a lock (100) with an inner half that releases the body (114). This exposes the internal components of the lock (100).

[0040] Figure 3A A latch (110) with rearwardly extending compression springs (140) is shown. These compression springs (140) tend to push the latch (110) forward into the extended position. The latch body (108, Figure 1A The stop within the latch (110) interacts with the latch to prevent it from extending beyond a specific point. The automatic extension provided by the compression spring (140) can be used for various functions, including when the door (102, Figure 1A The door automatically latches when closed. A compression spring (140) also provides a latching edge (119) to drive the latch (110) to engage with the door side post (104). Figure 1A The force of active engagement. In some designs, when the latch (110) is fully extended and engages with the latch body (108), Figure 1AWhen the stop in the lock (100) engages, there may be residual force exerted by the compression spring (140). This provides several benefits, including preventing the latch (110), compression spring (140), or other components from rattling when the lock (100) is not engaged, and providing a tendency to keep the latch (110) / latch edge (119) and the door side post (104) in contact. Figure 1A The force of the joint. When the door side post (104, Figure 1A This can be particularly useful when there is a small joint area and / or a sloping or curved profile. (See reference...) Figure 13A These contours are further described in Figure 13F.

[0041] exist Figure 3A In the diagram, the connecting element is a cable (206) rather than a ribbon (118). Figure 3B Cable (206) can have many advantages, including price, ease of attachment, and flexibility. It can also have some disadvantages, including concentrated abrasion / force beneath the cable (206), a relatively high profile cross-section, and a tendency for unpredictable movement / bending when the cable (206) is not tensioned. Unpredictable movement and buckling can become problematic if the cable (206) becomes tangled in internal components of the equipment or wedged into cracks and impedes movement. Even if the mechanical design allows the cable (206) or strip (118, Figure 1B It should always be taut, and there may be a possibility that the strip (118, Figure 1B The dynamic effect of the cable (206) being in a compressed state. For example, if the lock (100) is placed on the edge of the door and the door (102, Figure 1A If the door is suddenly closed, then when the ramp (115) of the latch (110) and the door frame (106) are engaged, Figure 1A ) and door side pillars (104, Figure 1A When engaged, the rapid movement of the latch (110) may cause the cable (206) or strip (118) to come into contact with the cable (206) or strip (118). Figure 1B ) relaxation.

[0042] exist Figure 3AThe example shown represents a single instance of a two-strand cable (206) or a double-strand cable (206). This is just one example, and many embodiments exist to overcome the disadvantages of the cable (206). Cables can be made from a variety of materials, including but not limited to monofilament cords, wires, thin strands, miniature steel cables, synthetic fibers, coated filaments, flexible shafts, braided stainless steel wires, shape memory alloys, or any other desired cable-like material. These cables can have a variety of geometries and cross-sectional shapes. For example, cables can have a non-circular profile to facilitate a high profile cross-section and buckling. Rectangular cables may be stronger, have more predictable buckling, and a lower profile compared to cables with a circular cross-section. Additionally or alternatively, cables can be incorporated into a variety of strip designs. For example, a strip can simply support the cables and hold them in a spaced relationship, while the cables provide most of the tensile strength required for the function of the mechanism.

[0043] U-shaped bracket (112) in Figure 3A As shown, it may have multiple features that enhance its function (e.g., a groove (142) and / or some other features (204)). In one embodiment, the U-shaped bracket (112) may have a recess or groove (142) extending wholly or partially along its length. The recess or groove (142) may have multiple functions, including providing for cables (206) or strips (118, Figure 1B ) passageway, and protect cables (206) or strips (118, Figure 1B ) to avoid being caught in the door (102, Figure 1A ) and door frame (106, Figure 1A This allows for the connection between cables (206) or ribbons (118). Figure 1B The smooth and unobstructed movement of the lock (100) and the smooth operation of the mechanism. Other features (204) may include various notches and cuts to help secure the bracket to the latch (110) and release body (114), to guide / position various moving parts, and in some cases to facilitate securing the lock (100) to the door (102, Figure 1A The spring / holding force on the ().

[0044] Figure 3AThe bottom shows various components of the release body (114), including a release slider (130), finger-shaped posts (155) or pegs extending into the release opening (144), and a slider housing (150). In some cases, it may be desirable for the release opening (144) to be completely covered by the slider housing (150), so that the user cannot see the interior of the release body (114). This prevents objects or debris from entering the release body (114). It also prevents the user's fingers, hair, jewelry, or other objects from getting stuck or trapped in the mechanism. In some embodiments, thin, flexible fins molded along the side of the release slider (130) may be present, which cover a portion of the release opening (144) as the release slider (130) moves forward and deflect within the slider housing (150) to provide a return spring force that pushes the release slider (130) forward when it is manually pushed backward. Alternatively or additionally, the release opening may be covered by a flexible and resilient membrane.

[0045] Figures 3B to 3F The structure and function of the lock (100) located between the door and the door frame, and between the door and the doorposts. (See above regarding...) Figure 1AAs discussed below in Figure 14, the door frame gap (105) between the door and the door frame, and the door side post gap (107) between the door and the door side posts, vary between door assemblies. For poorly installed or poorly maintained door assemblies, the door frame gap (105) and / or door side post gap (107) may be absent (e.g., the door rubs against the frame or the door does not latch because the door contacts the door side post too quickly) or very wide. However, for typical doors, the door frame gap (105) and / or door side post gap (107) are on the order of millimeters, with well-installed doors having a door frame gap (105) and / or door side post gap (107) between 1 and 5 millimeters. Therefore, in order to ensure broad compatibility of the lock (100) with a wide variety of door assemblies, the lock (100) structure residing in the door frame gap (105) and / or door side post gap (107) should have a minimum thickness. In some lock embodiments, this thickness is less than one millimeter. In other embodiments, the lock (100) structure residing in the door frame gap (105) and / or door side post gap (107) may be between 1 and 2 mm or greater in thickness. When the door frame gap (105) is small, it may be desirable that the strip (118) or cable (206) not be caught. This could significantly increase friction on the strip (118) or cable (206) and prevent it from moving smoothly (or not at all). Therefore, it may be desirable that the structure of the lock (100) surrounding the strip (118) / cable (206) prevents the strip (118) / cable (206) from being caught. It may also be desirable to have surfaces that control the movement of the strip (118) or cable (206) thereon. Ideally, these surfaces would be smooth and low-friction. However, if the strip (118) or cable (206) is exposed, it may come into contact with surrounding materials such as the door, door frame, or door side post. These surfaces may not be smooth or low-friction and could damage the strip (118) or cable (206). Therefore, in some embodiments, it may be desirable to enclose the strip (118) / cable (206).

[0046] Figure 3B A two-strand cable (206) is shown in a groove (142) within a U-shaped bracket (112). The groove (142) and the cable (206) are exposed and pass through gaps (door frame gap (105) and / or door side post gap (107). Figure 1A In this case, the cover (152) is placed above the groove (142) and the cable. Section AA shows the cross-section of the U-shaped bracket (112) structure, and... Figure 3C As shown in [the image]. Figure 3CIn the cross-section of the U-shaped bracket (112), a groove (142) has been formed therein, and the cable (206) slides within the groove (142) when the release mechanism is actuated. A covering (152), such as a film or sticker, is placed on the surface of the U-shaped bracket and covers the groove (142). This encloses the cable (206) and forms a closed and protected channel for the cable (206) / ribbon (118) to slide through.

[0047] Figure 3D A cross-section of an alternative embodiment is shown, wherein the U-shaped bracket (112) includes a cut-out segment (208). In this example, the cut-out segment (208) is located in the middle of the U-shaped bracket (112) and extends completely through the U-shaped bracket (112). For example, if the U-shaped bracket (112) is formed of a sheet of metal, the cut-out segment (208) may be a punched hole in the sheet of metal. Figure 3D The cut-out segment (208) is closed on both sides by a covering (e.g., a sticker (152)), and a composite instance of the strip (118) extends through the cavity formed by the cut-out segment. In this example, the composite instance of the strip (118) includes a cable (206) connected therebetween by the strip (118) or other structure. This composite instance of the strip (118) can have numerous advantages, including protecting the edges of the strip (118) from damage by the cable (206), and holding the cable (206) together and preventing tangling by the strip (118).

[0048] Figure 3E An alternative structure in which the U-shaped support (112) is formed of folded material is shown. For example, if the U-shaped support (112) is formed of a folded metal sheet, the metal sheet can be folded along the edge, wherein the folded portion (125) does not extend all the way to the middle of the central member. This leaves a channel extending downward along the length of the U-shaped support (112), and a strip (118) can be disposed in the channel and slide through the channel. Coverings such as films or stickers (see, for example, stickers (152)) are also possible. Figure 3D (This is not shown in this embodiment, but it can still be used.)

[0049] Figure 3FA cross-section of a U-shaped bracket (112) with a multi-layered structure on one side is shown, wherein a first spacer layer (153) creates a gap in the center of the structure, and a second covering layer (e.g., a sticker (152)) creates an enclosed space for the strip (118) to slide through. The spacer layers can be formed of a variety of materials, including stickers, double-sided adhesives, or other suitable films or sheets. In each of these embodiments, the stickers / layers serve a dual function: they shield the strip (118) from unintentional adhesion to external elements such as doors and door frames, and they hold the strip or cable in place to ensure reliable function. By shielding the strip / cable from unintentional contact with external elements, the risk of unintended damage to the strip / cable is reduced. By holding the strip or cable in place, the risk of tangling or jamming is reduced.

[0050] When considering the design of a structure that passes through a gap, several factors may be important. First, the entire structure can have a relatively thin cross-section while maintaining sufficient rigidity and resilience to hold the lock securely to the door. Therefore, the U-shaped bracket structure can be formed from metals such as stainless steel and various steel alloys. Some examples of potentially suitable materials include 304 stainless steel and steels with higher carbon content, such as 1095 steel. In some embodiments, using spring steel and / or steels with higher carbon content to increase stiffness and spring force may be helpful. Figure 3E As shown, the thickness of the entire structure can be on the order of millimeters, with 1 to 2 millimeters being acceptable and the target being 1 millimeter or less. However, in some cases, such as for locks attached to the top or bottom edges of a door where there may be a wide gap, the U-shaped bracket may be much thicker. The width of the bracket is not strictly limited and can range from 10 to 100 millimeters or more in some designs, with around 50 millimeters being a typical width.

[0051] Creating grooves or channels in a cost-effective manner can be challenging. Machining very shallow grooves can be challenging and time-consuming. For example, machining a 0.5 mm deep groove in 1 mm thick material may require special holding and stamping techniques to ensure the sheet metal is flat and securely held. Therefore, other designs (such as...) Figure 3D and Figure 3F The designs shown may be more cost-effective, but may not have the same performance as machined parts.

[0052] It may also be desirable that the grooves or channels through which the strip passes have no sharp edges or adhesive. For example, Figure 3C , Figure 3D and Figure 3FThe grooves in the channel are formed of metal and may have rough or sharp surfaces and edges. Therefore, it is desirable for the strip / cable to be positioned along the center of the groove / channel with minimal or no interaction with the edges of the groove. Additionally, it is desirable that there is no adhesive in the channel. For example, if the covering film is formed of sticker or other film with adhesive, it is desirable that the adhesive portion is away from the channel to prevent the strip or cable from being "stuck" by the adhesive. Despite these difficulties, the groove or channel serves several important functions: protecting the strip, preventing it from getting stuck, and acting as a guide to prevent the strip from deviating from its track.

[0053] Figures 4A to 4L Various views of an example of a lock (100) are shown. Figure 4A The right-side view of the lock (100) is shown. Figure 4B The front view is shown. Figure 4C and Figure 4D These are the top view and the bottom view, respectively. Figure 4E It is the left-side view, and Figure 4F This is the rear view. Figure 4G and Figure 4H These are the front perspective view and the back perspective view, respectively. Figure 4I and Figure 4J This is an internal view of the components within the locking mechanism (111). Figure 4K and Figure 4L This is a schematic diagram showing the interaction between the strip (118) and the release mechanism (113).

[0054] These figures illustrate a lock (100) comprising a latching mechanism (111) and a release mechanism (113) connected by a U-shaped bracket (112). Although the U-shaped bracket (112) is shown as a “U”-shaped bracket in some figures, the bracket can have any number of alternative shapes and sizes. For example, the bracket can be “L”-shaped and pass through a gap in the door without having a third side. In some embodiments, the bracket can have additional curves or other geometries. Multiple brackets can coexist. For example, a plastic component can have multiple metal parts attached to it to provide additional strength and resilience. Additionally or alternatively, two different brackets can coexist with a gap between them for communication. A variety of other configurations can also be implemented while carrying out the principles described herein.

[0055] As discussed above, the release mechanism (113) may include finger-shaped posts (155) that travel in an access opening (122) in the release body (114). In some embodiments, the release body (114) may also include one or more spring ramps (136). These spring ramps (136) can be used to tighten the clamping of the lock (100) onto the door when the lock (100) is positioned on the edge of the door. However, in some embodiments, spring ramps (136) are not used, and the resilience of the U-shaped bracket (112) is relied upon to apply the required normal force to secure the lock (100) to the door.

[0056] The latching mechanism (111) may include a latch body (108), a latch (110), and a latch locking element (132). In this example, the latch (110) includes a latch tip (148), which may be formed of a different and more gripping material. For example, the main part of the latch (110) may be formed of a tough and low-friction plastic (such as ABS). However, such a plastic may not be suitable for gripping a door side post. Therefore, different materials may be used for the latch tip (148). In one example, a separate piece may be molded from an elastomer and a high-friction material and mechanically and / or adhesively attached to the main part of the latch (110). Alternatively, insert molding or two-shot molding may be used to attach the elastomer material. This can form a latch tip (148) with excellent gripping force and supported by a stiffer body of the latch (110). For example, the material of the latch tip (148) may include silicone, thermoplastic elastomer, polyurethane, neoprene, EPDM (ethylene propylene diene monomer), nitrile rubber, vinyl, leather, foam, or any other desired elastomer material.

[0057] As discussed above and regarding Figure 9A and Figure 9B Further discussion suggests that the lock (100) may include a latching element (132). The latching element (132) may have various constructions and external profiles. In this example, the latching element (132) has at least one external rib that facilitates manual operation by a user. The design also includes a "haunch" or protrusion (156) extending to either side of the release body (114). These protrusions may have any of a variety of functions, including providing space for the latching mechanism (111), connecting internal structures to external portions of the latching body (108), or other functions.

[0058] In this example, the internal part (215, Figure 2G They are individually molded and slid into the outer shell of the latch body (108). Figure 4B The image shows an end view of the internal portion (215), which illustrates this cup-shaped form. Figure 4I and Figure 4JThe path of the strip (118) on the surface of the inner portion (215) is shown. For clarity, it has been shown from... Figure 4I and Figure 4J The latch body (108) was removed from the middle. Figure 4A The outer casing of the ). Figure 4I In this configuration, a surface on the inner portion (215) is adapted to receive and guide the strip (118). The strip (118) travels along this surface and is redirected to attach to the latch (110) and move the latch (110). Figure 4G , Figure 4H and Figure 4I As shown, the side tab (220) is received by the side protrusion (154) to help secure the inner portion (215) in the proper position within the outer casing of the locking body (108).

[0059] Figure 4J The attachment of the strip (118) to the underside of the latch (110) is shown. In this example, the strip (118) is secured using a block (222) and / or washers and screws (218). Other examples of attachments are shown in... Figures 7A to 7F As shown in the image.

[0060] Figure 4K This is a front view of the lock (100), in which the strip (118) passes along the groove (142) in the U-shaped bracket (112) and connects the latch (110) and the release slider (130). Figure 4L An exemplary attachment of a strip (118) is shown, comprising a block (222) secured by a screw (218). This connection method may be similar to... Figure 7C The connection method shown is illustrated. However, any of a variety of strip connection methods can be used. Figure 4L The differences between the finger posts (e.g., first finger post 155A and second finger post 155B) are also illustrated. The finger posts can have a variety of different constructions and geometries. In one embodiment, the first finger post (155A) has multiple exposed ribs, while the second finger post (155B) does not have ribs.

[0061] Figures 5A to 5H Various views of an example of an exemplary instance of the lock (100) are shown. Figure 5A The right-side view of the lock (100) is shown. Figure 5B The rear view is shown. Figure 5C and Figure 5D These are the top view and the bottom view, respectively. Figure 5E It is the left-side view, and Figure 5F This is the front view. Figure 5G and Figure 5H These are the front perspective view and the back perspective view, respectively.

[0062] These figures illustrate a lock (100) comprising a latching mechanism (111) and a release mechanism (113) connected by a U-shaped bracket (112). As discussed above, the release mechanism (113) may include finger-shaped posts (155) traveling in an access opening (122) of a release body (114). The latching mechanism (111) comprises a latch (110) and a latching body (108). In this embodiment, the latch ramp (115) comprises a plurality of wide, flat surface grooves and ridges. The ridges contact the door and door sideposts, while the grooves are slightly recessed, which alters the contact of the latch ramp (115) by varying the surface area of ​​the latch ramp (115) contacting the door frame / sidepost.

[0063] This embodiment also includes a slightly modified spring ramp (136). In this example, the spring ramp (136) is attached to only one end, rather than at both ends, to the release body (114). In some embodiments (where a larger and more repeatable spring force than that easily generated by a spring ramp (136) formed of or including plastic is required), the metal of the U-shaped bracket (112) can be bent or stamped into a spring shape that directly or indirectly contacts the door. For example, in Figures 5A to 5H In the embodiment shown, the metal of the U-shaped bracket (112) can be bent upward to support the spring ramp (136) (e.g., a spring ramp (136) formed of or including plastic).

[0064] like Figure 5A and Figure 5G As shown, the latch locking element (132) is placed on the latch body (108). In this embodiment, the manually operable surface of the latch locking element (132) is relatively low-profile and includes multiple ribs that facilitate manual engagement and disengagement of the lock with the latch (110). Figure 5F A front view of the lock (100) is shown, in which the latch locking element (132) is barely visible.

[0065] Figures 6A to 6H Various views of an example of an exemplary instance of the lock (100) are shown. Figure 6A The right-side view of the lock (100) is shown. Figure 6B The front view is shown. Figure 6C and Figure 6D These are the top view and the bottom view, respectively. Figure 6E It is a rear view, and Figure 6F This is the left-side view. Figure 6G and Figure 6H These are the back perspective view and the front perspective view, respectively.

[0066] These figures illustrate a lock (100) with a locking mechanism (111) connected by a U-shaped bracket (112) to a release mechanism (113). In this example, the U-shaped bracket includes a sticker (152) covering a strip (118) that points to... Figure 6B and Figure 6H The dotted outline in the image. In some embodiments, the sticker (152) wraps around the back of the U-shaped bracket (112). These folded edges (202) are in... Figure 6E and Figure 6G As shown, it helps to secure the sticker (152) in place. The U-shaped bracket (112) structure can be similar to Figures 3C to 3F Any of those structures shown, but one or more of the stickers (152) wrap around the opposite side.

[0067] These figures also show that the latching mechanism (111) includes a latch body (108) with a latch (110) and a latch locking member (132). In this example, the latch locking member (132) is a rounded protrusion without a ridge that facilitates manual engagement of the lock (100). While this makes the latch locking member (132) more in line with the product's design language, it also makes it more difficult to move. Therefore, it would be desirable for the latch locking member (132) to extend downward through the opening (224) to allow more of the rounded protrusion to be exposed.

[0068] The latch body (108) also includes a protrusion (160) on the top side. The protrusion (160) can be used for a number of purposes, including providing volume for the ribs to align with the top wall of the latch body (108) and reinforcing the latch body (108) so that the latch body (108) does not break when the latch (110) is engaged and the door is forcefully opened.

[0069] In this embodiment, the latch (110) includes a clamping pad (123) and a ramp (115). Generally, the minimum length of the ramp (115) is determined by the amount of extension of the latch (110). When fully extended, the ramp (115) must engage with the door frame and / or door side post, forcing the latch (110) to retract into the latch body (108). In most cases, this movement is counteracted by an internal spring in the latch body (108). The retraction of the latch (110) into the latch body allows the door to close, wherein the latch (110) spans across the door frame and door side post, and then extends behind the door side post for automatic locking.

[0070] This embodiment illustrates spring ramps (136) formed in the release body (114). These spring ramps (136) can replace Figures 1A to 1G The screw shown is 116. Figure 1AFor example, a spring ramp (136) can be used as a tightening element to securely hold the lock (100) in place around the door. As discussed above, these spring ramps (136) can be used to increase pressure on the door and allow the lock (100) to adapt to different door thicknesses. However, these types of features may not be necessary. Figures 8A to 8B As shown, the spring force of the U-shaped bracket (112) is sufficient to secure the lock in place. One element that helps secure the door is the latch side pad (210). This latch side pad (210) is attached to the underside of the latch body (108) and can be used for a variety of functions. The primary function of the latch side pad (210) can be to clamp the door. Therefore, the latch side pad (210) should typically be clamping rather than adhesive. In some cases, a similar instance of the release side pad (211) can be fastened to the opposite side of the release body (114). In some embodiments, the release side pad (211) can be used for slightly different functions. The release side pad (211) can be more resilient and thicker to apply a sustained force to the door. This may become more important in designs that do not use a spring ramp (136). The release side pad (211) can still be adhesive or sticky.

[0071] Figures 7A to 7F A diagram shows the connection of a strip (118) to a lock (100). Figure 1A Various connection methods for other components in ). Figure 7A A strip (118) with two notches cut out on either side of its ends is shown. The notches can be configured to fit into corresponding features in a housing or sliding element. Figure 7B Additional or alternative methods for connecting / anchoring a strip (118) are shown, the strip including holes or openings (194) in the strip (118) that mate with a post (230) or other feature. In other embodiments, such as Figure 7C As shown, the strip (118) can be clamped between the block (222) and the base (196). The block (222) can be secured in place in various ways and with any number of features to increase its clamping force on the strip (118). For example, the block (222) may have surface features such as textures, grooves, ridges, etc., to increase the friction and holding force of the connection with the strip (118). In some examples, the base (196) may have corresponding features to further increase the holding force of the connection. Figure 7C In the example shown, the base (196) includes a cavity configured to receive a block (222) and a strip (118). Figure 7DAnother method for attaching the strip (118) is shown. In this embodiment, a screw (218) and a washer (198) are used to secure the strip (118). The screw (218) passes through the strip (118) and into the base (not shown), while the washer (198) is used to clamp the strip (118) between it and the base (196). Figure 7E A strip (118) with a ring (200) is shown, which is formed by folding the strip (118) onto itself and forming a heat seal of the strip (118) to itself. The heat seal (232) secures two portions of the strip (118) together to form the ring (200). The ring (200) can be placed on a tab (234). Various methods exist for securing the ring (200) to a slot (117), including shaping the slot (117) such that it will hold the ring (200). Figure 7F An alternative method for securing the strip (118) is shown, which includes a strip (188) retracted around a rod (167). The end of the strip (118) may pass through a slot in the rod (167) or be secured to the rod (167). Alternatively, the rod (167) and the strip (118) may have sufficient friction to eliminate the need for a more mechanical connection. Although only a few connections are explicitly shown, a wide variety of connections are possible to implement the principles described. For example, cables or strips may be attached to a latch (110) by crimping, soldering, welding, using adhesives, using screws or bolts, using cable ties or straps, knotting, or some other means.

[0072] Although strips are shown and described in many of the embodiments illustrated herein, cables, cords, wires, tubes, and other elements can also be used to mechanically connect the two parts of a lock. Strips can have many advantages, including being thin enough that they will fit through the gap between the door and the door frame, distributing force across their width, and being relatively robust due to their width. Furthermore, due to their geometry, strips have a preferred bending / bending direction. For example, a strip will bend along an axis parallel to its width. A strip will not bend along an axis perpendicular to its width dimension.

[0073] Cables and ropes with more symmetrical cross-sections (e.g., circular, oval, or square cross-sections) offer numerous advantages, including simpler and more straightforward connection mechanisms. For example, ropes such as monofilaments have well-established knot and connection mechanisms that can be utilized in fisheries. On the other hand, ropes tend to bend in a more random manner and may become tangled or stuck inside the various channels and bodies of locks.

[0074] Depending on the material used for the strip, it may be beneficial to consider the material properties of the strip. For example, if the strip is prone to tearing when damaged or cut, some connecting mechanisms may be better than others. For instance, if the strip is prone to failure due to damage, clamping it between the block and the base (e.g., Figure 7C (as shown in the figure) or wound around the axis (as shown in the figure) Figure 7F (As shown in the figure) may be beneficial.

[0075] Figures 8A to 8F Various techniques for securing a lock around the edge of a door are shown. As discussed above, the lock will ideally be easy to install on the door, but once installed, it will remain securely in place on the door. Figure 8A A U-shaped bracket (112) formed of a resilient material such as steel or stainless steel is shown. The U-shaped bracket (112) bends inward such that when it unfolds to span the door (102), it applies a clamping force that secures it to the door, as... Figure 8B As shown in the figure. Figure 8C An exemplary lock with a U-shaped bracket (112) and a release mechanism (113) is shown. For illustrative purposes, the latching mechanism is not shown. In this example, the release mechanism (113) comprises several upwardly extending spring ramps (136). When the U-shaped bracket (112) is forcefully pushed against a door, the springs are compressed and exert a force on the door, which tightens the lock against the door. In this example, the springs are the spring ramps (136), which are shaped to facilitate insertion of the door edge into the U-shaped bracket (112). Figure 8D One or more screws (116) are shown that push the block (236) into the interior of the U-shaped bracket (112) when tightened. This can be used to tighten the U-shaped bracket (112) onto the door. Other embodiments may use a coil spring (238), such as Figure 8E Those shown. Figure 8F As shown, a cam mechanism (178) can be used. Figure 8F In the upper part (labeled "1"), the cam mechanism (178) in the release mechanism (113) is in the unlocked position, with the arrow indicating that the lever can rotate to engage the cam. In the lower part (labeled "2"), the cam mechanism (178) engages and tightens the lock onto the door. Several alternative methods are available for attaching the lock to the door if the user wishes to damage or alter it. These methods include the use of screws (116A, 116B) (such as...). Figure 8G (as shown) and the use of adhesive tape or adhesive strip (240) (as shown) Figure 8H (as shown in the image).

[0076] Figures 8A to 8F The mechanism shown is merely an illustrative example. There are various ways to removably attach a lock to a door. Figures 8C to 8FIn this design, the mechanism protrudes from the release mechanism (113) to apply force to the door. However, various other methods may be available. For example, the mechanism may extend from the latching mechanism (111) or from both the release mechanism and the latching mechanism. Additionally or alternatively, the entire release mechanism may be internally spring-loaded against a bracket, such that it extends into the gap where the door edge will reside. Various thicknesses and types of foam and adhesive pads may also be used with or provided with the lock to increase the lock's firmness against the door edge and / or accommodate doors of different thicknesses. In other examples, the bracket itself may be adjustable to accommodate doors of different thicknesses.

[0077] Go to Figures 9A to 9D The lock (100) may have several features, including a latch locking element (132). As shown above, the latch locking element (132) secures the latch (110) in the retracted position, thereby disabling the lock (100) and allowing the door to be easily opened and closed using a conventional door handle. In some cases, it may be desirable to lock the latch in its extended position. This helps ensure that the latch remains extended and engaged with the door side post, regardless of how a child shakes or forces the door open. However, the latch locking element should disengage before the lock can be opened by an adult, allowing the latch to retract.

[0078] Figures 9A to 9D An exemplary structure and principle for locking the latch (110) are shown. Figure 9A An exemplary example of a lock (100) is shown, which includes a latch locking member (132), a spring (184), and a latch (110) that includes multiple features (e.g., a notch (180) and / or an extended notch (182)) that can engage with the latch locking member (132) to lock the latch (110) in various positions. Figure 9A In the middle, the latch (110) is locked in the retracted position, in which the latch locking member (132) engages with the retracted notch (180). Figure 9B The same mechanism is shown, in which the latch (110) extends and the latch locking member (132) engages with one of the extended notches (182). In this example, there are multiple extended notches (182) that can be used to lock the latch (110) in different extended positions. The extended notches (182) used can depend on many factors, including the distance from the lock (100) to the door frame and / or door sidepost. Although the spring (184) is shown in the position where it pushes the latch locking member (132) into the notch (180) or the extended notch (182), a variety of other configurations can be used. In some designs, the latch locking member (132) may have a frictional or interference engagement with the notch (180) and / or the extended notch (182). Therefore, the latch locking member (132) will need to overcome friction or interference to both lock and unlock.

[0079] To move the latch (110) to different positions, the latch locking element (132) should first disengage. If the user is on the latch side of the door, this can be achieved by directly manipulating the latch locking element (132). However, on the release side of the door, disengaging the latch can be done indirectly using a connecting connection. Figure 9C The diagram illustrates a U-shaped bracket (112) connecting the release mechanism (113) and the locking mechanism (111). Two strips (e.g., a release strip (186) and a retraction strip (188)) are shown as passing from the release mechanism (113) through or across the U-shaped bracket to the locking mechanism (111). The release strip (186) is operatively connected to the locking element (132) and can be used to release the locking element (132). The retraction strip (188) can then be used to retract the locking element (110) if needed. Figure 9D A U-shaped bracket (112) connecting the release mechanism (113) and the locking mechanism (111) is shown. A strip (118) is present, passing through or across the U-shaped bracket (112) from the release mechanism (113) to the locking mechanism (111). In this example, a single instance of the strip (118) performs both functions. One embodiment of this design is shown in... Figure 9E As shown in the diagram. In this design, the path of the strip (118) passes through the rollers or other features of the latch locking member (132), such that when the strip (118) is tensioned (see arrow marked "1"), the latch locking member (132) is pulled downward to disengage from the extended notch (182) (see arrow marked "2"). The latch (110) can then be retracted by the force of the strip (see arrow marked "3").

[0080] Figures 10A to 10F Many alternative designs are shown. The preceding illustrative designs illustrate a mechanism that engages with the door's side posts using a sliding latch mechanism. However, these are merely examples. A variety of other constructions are possible. Figures 10A to 10F Many additional or alternative designs are shown. For example, Figure 10A A bracket (168) is shown that can be screwed onto a door frame (106) or a door side post (104). The bracket (168) can have various geometries, which can be selected to complement or adapt to a range of different lock designs. In this example, the bracket (168) is dovetail-shaped and secured by one or more screws (170). Dovetail brackets can offer many advantages, including forming a secure connection with a custom latching mechanism. However, the shape can vary. For example, if the latch is difficult to retract from a dovetail bracket with an inwardly sloping surface, the bracket can have different geometries and / or textures. Figure 10BAn alternative example of a bracket (168) with a flat surface and secured by screws or other suitable attachment methods (such as nails, staples, adhesives, or other techniques) is shown. In this case, the bracket is directly secured to the door frame (106) above the door sidepost (104). In this example, the door sidepost (104) has a curved surface that may make latch engagement difficult. The bracket (168) can be configured to present an alternative surface for latch engagement. Attaching the bracket may be useful for door installations that do not have door sideposts of the type shown in the figure. For example, in some countries, standard door installations are simply milled a portion of the door frame to install the door. Thus, the door frame becomes both the door frame and the door sidepost. Therefore, there is no edge for latch engagement. In this case, mounting the bracket to the door frame may be useful.

[0081] Figure 10C A lock (100) is shown that engages with a door frame (106) instead of a door side post (104). In this example, the lock (100) includes a base (172) and an elongated latch (110). The latch (110) extends over the door side post (104) to engage the door frame (106). This avoids many difficulties, including door side posts with surface profiles that are difficult to engage and with limited thickness. Generally, the door frame (106) is larger, stronger, and flatter than the door side post (104). However, it is further from the surface of the door and therefore requires a larger latch (110).

[0082] Figure 10D An alternative example of a lock (100) is shown, which includes a rotary latch (110) engaging with a door side post (104). This lock (100) can have several advantages, including a more direct transmission of force when a person attempts to open the door (102). A pivot (174) is located close to the door side post (104), and when the door (102) is being forcefully opened, the tension in the latch (110) is transmitted through the pivot (174) to the door (102) with the minimum amount of torque / leverage force that the lock (100) must withstand. From a mechanical point of view, the lock (100) is a robust design as long as it is securely fastened to the door.

[0083] Figure 10E It shows something similar to Figure 10D The lock (100) of the mechanism shown is an example. However, in this example, the latch (110) can be released by a release pull (176). The release pull (176) can take many different forms, including a wide, flat band with handles at its ends to facilitate a user gripping and pulling it to release the latch (110). The arrows illustrate how the latch (110) will open once the release pull (176) has been pulled.

[0084] Figure 10FDifferent examples of the lock (100) are shown, which include a cam mechanism (178) for engaging a door side post (104). To lock the door (102) closed, the cam mechanism (178) rotates to engage the door side post (104). An advantage of the cam mechanism (178) is that it can continue to rotate to tighten the door (102) in the closed position. This allows the lock (100) to hold the door (102) in a tightly closed position and prevents the door (102) from rattling. In some embodiments, the cam mechanism (178) may include a torsion spring and a ratchet mechanism, which allows the cam mechanism to automatically tighten when the door is closed. In some embodiments, the release pull (176) does not actually rotate the cam mechanism (178). Instead, it simply disengages the ratchet or cam mechanism (178) and allows the cam mechanism (178) to rotate open when the door is opened.

[0085] Figure 11 An illustrative example of a door (102) is shown, featuring a door frame (106) and locks (100A, 100B) attached to the door (102) in different locations. In this example, the lock (100B) is inserted around the door (102) above the door handle (103), away from the reach of young children, thus preventing them from opening the door (102). In another example, the lock (100A) may also be attached to the top section of the door. The position of the lock (100) on the door (102) will depend on the user's preference, as the device is designed to have a secure clamping hold around any door surface.

[0086] There are many different constructions and mechanisms that can be used for locks. For example, Figure 12A lock (100) including an electrically actuated latch (110) is shown. The latch body (108) may include a variety of actuators, including solenoids, electric motors, gearboxes, linear actuators, rotary actuators, electromagnetic actuators, or other types of mechanisms configured to move or release the latch (110). On the opposite side of the door (102), the release mechanism (113) may include electronics, batteries, release triggers, lights, cameras, or any other desired electrical or mechanical devices. For example, the release trigger may include a fingerprint reader or other biometric device, a button, a camera with facial or other recognition capabilities, a keypad, a combination lock, a scanner, a barcode / barcode reader, an RFID reader, a touchscreen, multiple sensors, or combinations thereof. In this example, a release button (131) is illustrated on one side of the release mechanism (113). However, this is merely an example. One or more buttons may be on any other suitable surface and constructed in a variety of ways. The U-shaped bracket (112) may include mechanical and / or electrical components. For example, the U-shaped bracket (112) may include mechanical elements designed to secure the device to the door (102) and electrical components for communication between the release mechanism (113) and the latching mechanism (111). In one embodiment, the U-shaped bracket (112) includes one or more conductors and a metal frame to protect the conductors and mechanically connect the two parts of the lock (100). For example, the conductors may be wires, traces of flexible circuitry, strips, cables, or other conductors.

[0087] The above description is merely illustrative. Many other configurations can be used. For example, in some embodiments, the U-shaped bracket may not be included. Instead, components on opposite sides of the door can communicate via various electronic devices, including but not limited to Bluetooth, Wi-Fi, RFID, or other wireless protocols. In other embodiments, magnetic or electromagnetic communication can be used to signal between components on either side of the door. Additionally, the mechanical support provided by the U-shaped bracket may not be necessary. For example, the latching mechanism may be threaded or otherwise secured to the door, and the release mechanism may simply be attached to the door, door frame, wall, or other location. In some embodiments, the release mechanism may be virtual, such as an application running on a mobile device or other device, or an RFID tag that can be read through the door by the latching mechanism.

[0088] Additionally or alternatively, the lock (100) may have pneumatic or magnetic components. For example, the connection between the release element and the latch may be a mechanical structure in the form of a small tube of pressurized liquid or gas acting on a piston to retract the latch. A magnetic latch and communication with the lock may also be present.

[0089] Figures 13A to 13E The description of the latch (110, is shown.) Figure 1AVarious schematic diagrams of the interaction between the door frame (106) and the door side post (104). Figures 13A to 13D This is a schematic cross-sectional view of the door frame (106) and door sideposts (e.g., first door sidepost (104A), second door sidepost (104B), third door sidepost (104C), and fourth door sidepost (104D)). In many door installations, the door sideposts (104) are made of wood or other decorative elements, typically nailed or bolted in place to the door frame to stop the door from moving when it is closed and latched. Generally, the door contact surface (162) of the door sidepost (104) is flat and perpendicular to the door frame (106). This allows the door sidepost (104) to contact the flat surface of the door when it is closed, thereby preventing further movement of the door.

[0090] However, the other side of the door side post (104) (e.g., the first contact surface (164A), the second contact surface (164B), the third contact surface (164C), and the fourth contact surface (164D)) can have more varied constructions. For simplicity, the other side or contact surface (164) of the door side post (104) is referred to as the "latch contact surface" because this is where the latch (110, Figure 1A Typically, the surfaces to be joined are shown. In these schematic diagrams, the door sideposts (104) have different cross-sectional profiles, ranging from grooved edges (see, for example, the first door sidepost (104a)), rectangular edges (see, for example, the second door sidepost (104B)), and various rounded profiles (see, for example, the third door sidepost (104C) and / or the fourth door sidepost (104D)). The profile of the latch contact surface (164) can obviously make a secure connection between the latch tip (166) and the door sidepost (104) easier or more difficult. Generally, a larger latch contact surface (164) that is perpendicular to the door frame (106) is easier to securely connect to. For example, in Figure 13B In some embodiments, the latch contact surfaces (e.g., the second contact surface (164B)) are large, flat, and perpendicular to the door frame, making it easier for the latch tip (166) to engage. However, the latch contact surfaces (e.g., the first contact surface (164a)) are much narrower flat surfaces that transition into a curved, sloping surface, which may be difficult for the latch tip (166) to grip. Other latch contact surfaces (e.g., the third contact surface (164C) and / or the fourth contact surface (164D)) do not have flat surfaces at all, but have rounded profiles. Therefore, in some exemplary embodiments, the lock (100, Figure 1AThe latch is configured to use a certain amount of normal force to push the latch tip (166) into the door frame (106), ensuring a secure engagement between the latch tip (166) and the door side post (104). For spring-loaded latches, this is achieved by the spring forcefully pushing the latch against the door frame, ensuring that the latch's travel is greater than the distance to the door frame. This is in Figure 13C The diagram shows the contact tip in its fully extended position, outlined by a dashed line. In the position with the solid line outline, the spring force is applied perpendicular to the door frame, as indicated by the arrow.

[0091] The angle at which the latch engages with the door side post can also affect the performance of the lock (100). For example... Figure 13E As shown, there is a latch (110, Figure 1A The lock (100, 104) can engage with a wide range of angles, including the door frame (106) and the door side post (104). Each of the different angles has its advantages and disadvantages. Locks (100, 104, 105, 106, 107, 108, 109, 10 ... Figure 1A Examples. For example, Figure 9A and Figure 9B The lock (100) engages with the door side post at an angle that tends to extend the latch when someone attempts to open the door. Figure 12 The lock engages at a 90-degree angle with the door side post, and attempts to forcefully open the door while the latch is engaged have a generally neutral effect, regardless of whether the latch slides in or out. Many of the exemplary locks described herein (see, for example) Figures 1A to 1G , Figures 2A to 2I , Figures 4A to 4J The latch operates in the "extended" arc, where the door opening force tends to cause the latch to extend further out of the latch body. This can result in the lock remaining engaged with the contact surface when force is applied to the door. Figure 10E The lock in the middle has a pivot (174, Figure 10E The swing lock (110, Figure 10E The pivot is connected to a release pull (176) that travels below the latch contact surface (164, FIG. 13). In this case, the latch (110, Figure 10E The tension is put on by someone trying to open the door.

[0092] Figure 13E The door frame (106) and door side post (104) are shown, wherein the latch (110, Figure 1AThe various engagement angles of the latch are arranged in a 180-degree semicircle around the contact surface. These angles are divided into various arcs. Some implications of designs engaging the contact surface at various angles will be discussed. For example, for a latch that moves / slides at an angle in the "retracted" arc, the force of opening the door tends to retract the latch and disengage it. Therefore, the mechanism moving the latch tends to, and must, resist the force applied by moving the door. Thus, for a design that engages the latch contact surface (164) by moving at an angle in the retracted arc, it may be desirable to have a locking mechanism that prevents the latch from retracting. This locking mechanism transmits the force from the door being opened to the latch body and the door, rather than through other actuating mechanisms in the lock. To open the door, the user must first disengage the internal locking element and then retract the latch. Figures 9A to 9D Examples of locks including internal locking elements are given in the figures. Locks with internal locking elements (such as the sliding locking elements shown in these figures) can be used in a wide variety of locks, but are particularly useful for locks that engage along a vector along a retraction arc.

[0093] Most conventional door locks have a contact angle with the door frame along the neutral axis (90 degrees to the door frame). For example, a conventional door handle mechanism slides perpendicular to the door frame. As discussed above, many of the exemplary designs in this paper operate in an "extended" arc. This provides the benefit of a more secure interaction with the door side post, and the shallow extended angle used generally allows the slide to retract when the lock is opened. For locks operating in a "tensioned" arc, a slide retraction mechanism would typically be unsuitable because the movement of the slider does not easily disengage the contact tip from the door side post. However, a variety of other mechanisms, such as rotary or oscillating mechanisms, can be used.

[0094] The examples given above are merely illustrative of the principles described. A wide variety of mechanical and / or electrical concepts of varying complexity exist that can be used to engage between a door and its frame to prevent the door from moving until the lock disengages.

[0095] Figure 14A and Figure 14B Various diagrams related to the gap between the door and the door frame are shown. Figure 14AA door (102) is shown fitted into a door frame (106) and supported by hinges (158). Typically, the door (102) will be installed such that the gap between the door (102) and the door frame (106) is uniform, and the door (102) remains square with respect to the door frame (106). However, if the door is installed carelessly, the width of the gap may vary. Typically, the vertical gap on the side of the door with the handle is carefully controlled during installation. This is because the vertical gap has a stronger impact on the function and aesthetics of the door than other gaps. The gap determines how the door works for several reasons. If the gap is too small, the door will hit the doorposts and cannot be closed, or if the door is closed, it may be difficult to open. If the gap is too large, the latch on the door handle may not engage securely with the latch plate / cutout in the door frame. The horizontal gaps at the top and bottom of the door are poorly controlled and tend to be larger. For example, the gap at the bottom of a door can be intentionally left larger to allow for airflow and clearance for floor coverings such as carpets or mats. The gap at the top of a door is typically smaller, less visible to the user, and can still be significantly larger / worse controlled than a vertical gap.

[0096] Regardless of how a door was initially installed, gaps can change over time due to various reasons, such as improper use, the weight of the door, displacement of the door frame / wall, warping, or other effects. This causes changes and shifts in the gaps around the door, and may result in uneven gaps around the door. Figure 14A An illustrative example of a door (102) with a typical pattern of uneven gaps is shown, which indicates the weight of the door causing the door (102) to sag. For illustrative purposes, these gaps have been exaggerated. The vertical gaps are narrow at the top and widen towards the bottom of the door. The horizontal gaps are wide near the left side of the door frame and gradually narrow towards the hinges (158). Because the lock (100) is to be placed out of reach of children, it should be positioned along the upper portion of the vertical gaps or along the horizontal gaps at the top of the door (typically towards the door handle side) on the door edge. Therefore, it may be helpful if the lock (100) is constructed to manage both narrow and wide gaps. To work in narrow gaps, the U-shaped bracket (112) can be relatively thin so that the door (102) will still be closed when the lock (100) is in place. The latch (110) should be configured to engage the door stop / side post (104) at a variety of distances, including a short distance for narrow gaps and a longer distance for wide gaps. In some examples, the extension or range of the latch (110) may be configured to engage a door side post (104) that varies by a distance of up to 25 mm or more. In other designs, the extension may be smaller or larger. Figure 14A A lock (100) fixed to the upper edge of the door (102) is shown. Figure 14BA cross-sectional view of a lock (100) on a door (102) is shown, wherein a U-shaped bracket (112) spans the door (102), and a release mechanism (113) is on one side of the door (102), and a latching mechanism (111) is on the opposite side of the door (102). A latch (110) extends from the latching mechanism (111) to engage with the door frame (106) and / or the door stop / door side post (104). Because it is desirable for the latch (110) to engage securely with the door stop / door side post (104), it may be advantageous for the latch (110) to have an extension greater than the distance between the latch (110) and the door frame (106). This allows the residual spring compression within the latch mechanism (111) to press the latch (110) against the door frame (106) and allows the latch (110) to engage with the typically small or angled profile of the door stop / side post (104). As discussed above, this distance is affected by the horizontal or vertical clearance between the door (102) and the door frame (106). Therefore, in order to maintain compatibility of the lock (100) with a wide variety of doors and door mechanisms, it is advantageous for the latch (110) to have a suitable range of travel for engagement with the side post (104). A longer range of travel has several effects that can be suitably designed, including a larger lever arm, greater internal force, longer sliding and spring mechanisms, etc.

[0097] Figure 15 An exemplary method for installing a lock (1500) is described. The method may include: selecting a door to which the lock is to be secured (step 1505); determining the height at which the lock should be placed on the door to prevent children from approaching the lock (step 1510); opening the door and pressing the lock against the edge of the door at approximately the predetermined height (step 1515); and fully closing the door to engage the lock and preventing the door from being opened without first releasing the lock (step 1520).

[0098] The illustrative method described above is merely an example. Various implementations exist. For example, steps may be reordered, repeated, deleted, or additional steps may be added. In one example, by placing the lock on the horizontal top edge of the door, the step of determining the height at which the lock should be placed to prevent children from approaching it can be omitted. There is no higher position on the door than this.

[0099] In some buildings, doors may have different thicknesses. Therefore, the lock can be adjusted in various ways, including by changing the thickness of the pads or layers on the inside of the release mechanism and / or latching mechanism. In some embodiments, the metal bracket may be adjustable. In other embodiments, the latching or release mechanism may have adjustable attachments to the metal bracket, thereby increasing or decreasing the width of the opening receiving the door edge.

[0100] Although the lock (100) can be specifically described and is suitable for preventing children from opening doors, the principles described herein have broad applicability to a range of different lock designs and functions. These principles may be useful in designing locks for the elderly, pets, interior doors, exterior doors, and a range of door sizes and types. Locks designed according to the described principles can provide one or more of the following benefits: quick and easy installation with or without tools or fasteners; the lock allows the door to be fully closed when installed; the lock can be opened from both sides of the door; and in many cases, the lock can be installed and made functional without altering or damaging the door and door frame in any way. These principles illustrate numerous examples where the lock automatically engages with the door when it is closed, but may have a disabling mechanism (e.g., a latch lock) that allows the lock to be disabled, allowing the door to operate in the normal manner. In addition, these principles teach that various lock designs can produce locks that are easy to install, easy to remove, and easy to adapt to changing environments. Furthermore, the functions of various designs can produce locks that are easy to engage and easy to open with one or two hands.

[0101] For example, if parents are concerned about their children going to the pantry, they can install a lock on the pantry door. However, when parents are actively working in the kitchen, they might want the lock to disengage so that adults don't have to unlock it every time they enter the pantry. When parents are working in the kitchen, they can engage the latch and secure it in the retracted position. Alternatively, because the lock is so easy to install, parents can simply remove it while they are in the kitchen and reinstall it when the food is ready. Similarly, if parents decide that a different door (such as the door leading to the stairs) is more secure, the lock can be easily moved to that door. If there is a particularly narrow vertical gap between the door and the door frame, the lock can be moved to the top edge of the door where there is more space. Similarly, if a child grows up and uses a chair to reach the lock, the lock can be moved to a higher position on the door or placed on the top edge of the door.

[0102] This lock can be used to lock pets or pet doors. If a pet has already figured out how to open the door itself (such as a dog that can manipulate a door lever handle), the lock can be used to close the door securely where the pet cannot reach it. If a pet door needs to be locked, the principles described in this article can be used to design a modified pet door lock that is easy to install and operate.

[0103] If there are elderly people with mental health issues, it may be desirable to prevent them from entering certain rooms of the house and / or leaving the house without supervision. Locks may be installed in places that the elderly person cannot reach, or may be beyond their experience, making it impossible for them to open the locked doors.

[0104] Further applications of the described principle can be made to any door or gate where it is desired to be closed tightly, such as garden gates, barn doors, sheds, vehicle doors, commercial buildings, access hatches, or other covered openings.

[0105] As discussed above regarding the mechanical design, one end of the strip (118) or cable (206) is attached at point 124 of the strip attachment and extends through the internal structure of the latch body (108). It then loops back around the U-shaped bracket (112) to ensure a secure and guided path. The strip (118) continues to slide through the groove (142), which guides the strip (118) toward the lower section of the lock (100). This arrangement facilitates the intended movement and function of the lock (100) mechanism.

[0106] In some embodiments, the U-shaped bracket (112) formed of metal is characterized by a groove (142) that is precisely engineered to allow the strip (118) to pass through seamlessly. A strategically placed sticker (152) covers the exposed portion of the strip (118), both to shield its movement within the U-shaped bracket (112) and to conceal the portion, thereby preventing contact with the door frame. In this embodiment, the sticker (152) may employ a specialized adhesive applied to its outer edges to ensure a secure attachment to the U-shaped bracket (112), while deliberately omitting adhesive from the center portion to avoid interfering with the free movement of the strip (118). In some embodiments, alternative attachment methods for the sticker (152) are employed to enhance adaptability to different environmental conditions or mechanical requirements. These methods include the use of: double-sided tape, which provides reversible attachment; heat-activated adhesives, which provide enhanced durability under varying temperature conditions; magnetic stickers, which are suitable for temporary placement; Velcro strips, which allow for easy repositioning; and snap-on caps, which provide non-adhesive fixation options. Furthermore, the stickers (152) can be attached using other innovative adhesive materials tailored to specific operational needs.

[0107] In one embodiment, the door lock includes a first component on a first side of the door and a second component on a second side of the door. The structure mechanically connects the first and second components through a gap between the door and the door frame and a communication connection between the first and second components. In some examples, the communication connection may include a mechanically controlled connection between the first and second components. Additionally or alternatively, the communication connection may be one of a wired communication connection and a wireless communication connection. The communication connection may pass through the gap between the door and the door frame. The structure may include a slot for the communication connection. The slot may be a slot, recess, or opening, or a combination thereof. In some embodiments, the structure may surround the communication connection on at least two sides. In several embodiments, the structure may surround the communication connection on at least four sides. In some examples, the structure may include a cover on each side through the slot, such that the communication connection is sandwiched between the covers. The communication connection may include at least one of the following: an electrical ribbon cable, a mechanical ribbon, and a mechanical cord.

[0108] In one example, a first component of the door lock may include a manually actuated slider disposed on a first side of the door, opposite a door side post. A second component may be disposed on a second side of the door adjacent to the door side post. The second component may include a slidable latch that extends to engage with the door side post and prevent the door from opening. A structure mechanically connecting the first and second components may include a U-shaped bracket that passes through a gap between the door and the door frame and connects to the first and second components. The U-shaped bracket may include a clearance path for a communication connection. The communication connection may include a tension member connected to the manually actuated slider of the first component and the slidable latch of the second component, such that when the manually actuated slider is actuated, the slidable latch disengages from the door side post to allow the door to be opened.

[0109] Based on the principles described herein, an exemplary door lock may include a first component disposed on the side of a door opposite a doorpost. The first component may include a manually actuated slider. A second component may be disposed on the side of the door adjacent to a doorpost, and this second component may include a latch configured to extend and engage with the doorpost to prevent the door from opening. The door lock may also include a structure mechanically connecting the first and second components, wherein the structure includes a U-shaped bracket connecting the first and second components and passes through a vertical gap between the door and the door frame when the door is fully closed, or through a horizontal gap between the door and the doorpost when the door is fully closed. The structure also includes a clearance path. A tension member is disposed in the clearance path and is connectable to the manually actuated slider of the first component and the slidable latch of the second component, such that when the manually actuated slider is actuated, the slidable latch disengages from the doorpost to allow the door to be opened.

[0110] In one embodiment, the door lock may include a disengaging member on a first side of the door and latching members on a second and opposite side of the door. The lock may also include a connection between the disengaging member and the latching members such that activation of the disengaging member causes the latching members on the opposite sides of the door to disengage, thereby allowing the door to be opened. In this example, the door is locked in the closed position, and the connection is made through the gap between the door frame and the door.

[0111] In another embodiment, the lock may include a cavity for receiving the edge of a door, a latch on a first side of the door, and a release mechanism on a second side of the door, wherein the lock is designed to be mounted on the edge of the door without tools and without damaging the door or door frame. Furthermore, when locked, the lock secures the door in a fully closed position. In this example, the lock may be configured to be opened from either side of the closed door. Additionally, the lock may be mounted at any desired height along the vertical edge of the door and can be installed by manually pushing the lock onto the edge of the door.

[0112] A door lock may include a first component on a first side of the door and a second component on a second side of the door, wherein the structure mechanically connects the first and second components through a gap between the door and the door frame, wherein the gap is defined by the door being fully closed and the door latch being received in the door frame. The door lock includes a latch for engaging with a feature attached to the door. This feature may be the door frame, a door side post, a user-installed feature, or another feature.

[0113] Therefore, the locks described herein offer numerous advantages, including installation in seconds without tools or damage to the door, allowing the door to be fully closed when the lock is in the proper position, securely locking the door while still allowing both the lock and the door to be opened from both sides. Ensuring the door is fully closed when the lock is in the proper position is important, at least for the following reasons.

[0114] The described principles provide for a wide variety of locks that are easy to install on the edge of a door and remain in place once in place. Exemplary locks can work with a wide variety of doors, including interior doors and doors of varying thicknesses. The locks securely clamp door side posts, door frames, brackets, or other elements attached to the door frame. The locks can be smoothly and easily opened from both sides of the door with reasonable force.

[0115] In one embodiment, a door lock may include a first component to be secured to one side of a door and a second component to be secured to the opposite side. These two components are mechanically connected by a structure passing through the gap between the closed door and the door frame. A communication connection between the first and second components facilitates their interaction. The communication connection may be a mechanical, wired, or wireless connection, and it is designed to pass through the gap between the closed door and the door frame. The structure includes a gap for the communication connection and surrounds the communication connection on at least two sides, with some embodiments surrounding the communication connection on all four sides.

[0116] The gap can take the form of a channel or slot within the structure. In some designs, the slot is covered on each side, so the connecting connection is sandwiched between the covers, thus ensuring protection and secure placement. The connecting connection itself can be an electrical ribbon cable, a mechanical ribbon, or a mechanical rope.

[0117] One embodiment of the door lock features a manually actuated slider on a first component positioned on the side of the door opposite a doorpost. A second component, located near the doorpost, includes a slidable latch that extends to engage with the doorpost, thereby preventing the door from opening. The structure connecting the first and second components includes a U-shaped bracket that extends through a gap between the door and the door frame when the door is fully closed. The U-shaped bracket includes a communication path for a tension member connecting the manually actuated slider of the first component and the slidable latch of the second component. When the slider is actuated, the latch disengages from the door frame, allowing the door to be opened.

[0118] Additionally, some examples include locks with structures designed to fit through the gap between a door frame and a closed door, characterized by a latch that engages with an existing feature of the door frame or door sidepost. A release mechanism is connected to this structure, allowing the latch to disengage from the existing feature of the door frame or door sidepost. The structure is configured to position the release element on one side of the door and the latch on the other side, having a communication connection that facilitates interaction between the release element and the latch. This communication connection can be a strip or an electrical connection.

[0119] Another embodiment of the lock includes a latch and a release mechanism connected by a bracket, which attaches around the edge of the door when the door is closed, thereby securing the latch and release mechanism to opposite sides of the door. The bracket may include a slot or channel for receiving a communicating connection, which may be a mechanical linkage, cable, strip, or wire. The release mechanism is characterized by a manually operable slider that, when actuated, retracts the latch. The latch is biased toward an extended position by a spring mechanism, and the bracket includes a resilient material that clamps against the door surface without causing damage, thereby maintaining the lock's position when the door is fully closed.

[0120] Overall, the described door lock is designed for easy installation without tools, without damaging the door or frame, and allows the door to be fully closed while securely locked, yet easily opened from both sides. The lock is adjustable for different door thicknesses and provides a firm engagement with door side posts or frames, making it a versatile and user-friendly security solution.
