Description

Technology Field

[0001] The present disclosure relates to a coupler device for detachably connecting an opening / closing cover of an article to a main body. Background Technology

[0002] Various conventional items, such as portable bags, toolboxes, equipment cases, storage boxes, and electronic device storage boxes, generally have openable covers, and coupler devices are used to secure or release these covers to the main body. Such coupler devices are generally configured in the form of buckles, snap buttons, latches, magnetic fasteners, etc., and function to open and close the cover of the item according to the user's operation. In particular, when the item to be secured is a bag, a push-type buckle structure made of plastic or metal installed on the side or front has been widely used.

[0003] However, since most of these conventional coupler devices feature externally exposed push or pull mechanisms, problems may arise where the coupler comes loose due to external impact or friction, regardless of the user's intent. This can lead to a risk of loss or damage to the contents of the product, and such accidental release entails significant inconvenience and danger, particularly for products used outdoors or while in transit.

[0004] Furthermore, most conventional structures require the use of both hands or specific force and positional manipulation, making it difficult to operate with one hand or without a clear line of sight. This causes inconvenience in situations where a cover must be opened or closed while carrying loads or wearing gloves, and accessibility and operability may be further degraded, particularly for the elderly or children.

[0005] Furthermore, since these coupler devices generally have simple structures and limited design elements, their application is restricted in markets requiring high-end products or brand differentiation due to aesthetic limitations and a lack of functional expandability. Even in products requiring complex functions, such as integrating handles, locking mechanisms, and direction fixing capabilities, conventional couplers suffer from reduced design flexibility due to their structural constraints.

[0006] In this regard, there is a growing need for a new coupler device that allows users to easily release the coupler by performing only a rotational motion with one hand, while ensuring the cover is securely fixed without malfunction caused by external impact or unintentional force. Furthermore, there is a demand for technology that is resistant to repeated use and can simultaneously improve the aesthetic appearance and ease of use of the product. The problem to be solved

[0034] FIG. 1 is a diagram illustrating a safety coupler device of an article according to one embodiment mounted on an article. FIG. 2 is a conceptual diagram illustrating a safety coupler device of an article according to one embodiment in which a mount and a button are coupled to each other when the second part of the article is in a first article state where the second part of the article covers the first part. FIG. 3 is a conceptual diagram illustrating a safety coupler device of an article according to one embodiment in which a mount and a button are separated from each other when the second part of the article is in a second article state where the second part of the article does not cover the first part. FIG. 4 is an exploded view illustrating a safety coupler device of an article according to one embodiment with the mount and the button separated from each other. FIG. 5 is a diagram illustrating the mount of FIG. 4 from a different angle.

[0035] Referring to FIGS. 1 to 5, the safety coupler device (1) of an article may be configured to connect a first part (B1), which is part of the article (B), and a second part (B2), which is another part of the article (B) provided to cover the first part (B1), so as to be separable from each other.

[0036] For example, the article (B) may include, but is not limited to, a device for storing items such as a bag. For example, the first part (B1) of the article (B) may refer to a main body in which items are accommodated among the components of a bag, and the second part (B2) may refer to a bag cover connected to the main body and provided to cover the main body, but is not limited to.

[0037] For example, the state of an article (B) in which the second part (B2) is positioned to cover the first part (B1) can be defined as the first article state (BP1), and the state of an article (B) in which the second part (B2) is positioned not to cover the first part (B1) can be defined as the second article state (BP2). As will be described later, the coupler assembly (AS) can combine the first part (B1) and the second part (B2) with each other when the article (B) is in the first article state (BP1).

[0038] The safety coupler device (1) of the article may include a mount (200) installed in a first part (B1). The mount (200) may represent a part of the safety coupler device (1) of the article. The safety coupler device (1) of the article may include a button (100) installed in a second part (B2). The button (100) may represent another part of the safety coupler device (1) of the article. The mount (200) and the button (100) may be detachably coupled to each other.

[0039] More specifically, the mount (200) may include a mount body (220) having a surface facing the second part (B2) when the second part (B2) is in a first article state (BP1) in which the second part (B1) is covered, a fastening plate (230) arranged to be connected to the mount body (220) and positioned on the opposite side of the mount body (220) with respect to the first part (B1), and a first magnetic body (201) installed on a surface (221a) of the mount body.

[0040] The mount body (220) and the fastening plate (230) may include a plate shape that is approximately disc-shaped, but are not limited thereto. The first part (B1) may be positioned between the mount body (220) and the fastening plate (230).

[0041] The first magnetic body (201) may be positioned in the central part of the mount body (220). For example, the first magnetic body (201) may be installed on one side (221a) of the mount body positioned to face the second part (B2). The first magnetic body (201) may be detachably coupled with the second magnetic body (1014, described later) installed on the button (100).

[0042] The mount (200) may further include a mount groove (210) formed by being recessed on one side (221a) of the mount body and extending in a direction corresponding to the direction in which the outer circumference of the mount body (220) extends, and a coupling pin (2111, 2121) disposed on one side of the mount groove (210) and extending in a direction intersecting the direction in which the mount groove (210) extends, and detachably coupled to the button (100).

[0043] The mount groove (210) may be formed by being recessed in one side (221a) of the mount body to have a shape that corresponds approximately to a part of the arc of a circle, and the coupling pins (2111, 2121) may be arranged to be received in the mount groove (210). As will be described later, when the coupling hooks (111, 112) of the button (100) are coupled with the coupling pins (2111, 2121) of the mount (200), the button (100) and the mount (200) can be fixed to each other, and when the coupling hooks (111, 112) and the coupling pins (2111, 2121) are released, the mount (200) and the button (100) can be released from each other.

[0044] For example, the mount groove (210) may include a pair of mount grooves (210). The pair of mount grooves (210) may be arranged symmetrically with respect to the center of the mount body (220). For example, the pair of mount grooves (210) may be arranged symmetrically in opposite directions with respect to the first magnetic body (201).

[0045] The coupling pins (2111, 2121) may comprise a pair of coupling pins (2111, 2121), including a first coupling pin (2111) positioned adjacent to one end of a first mount groove (211), which is one of a pair of mount grooves (210), and a second coupling pin (2121) positioned adjacent to one end of a second mount groove (212), which is the other of the pair of mount grooves (210), positioned symmetrically with respect to the first coupling pin (2111) with respect to the center of the mount body (220). For example, the first coupling pin (2111) and the second coupling pin (2121) may be arranged symmetrically in opposite directions with respect to the first magnetic body (201).

[0046] For example, the extended length of the mount groove (210) may be formed to be greater than the value obtained by multiplying the distance (d) at which the mount groove (210) is spaced from the center of the mount body (220) by pi (π) and dividing that value by 4 (*π / 4). This may limit the rotation radius of the first detachable plate (110). An explanation regarding this will be provided later. The button body grooves (1011, 1012, described later) and the through grooves (123, 124, described later) may be formed to be extended to correspond to the extended length of the mount groove (210).

[0047] The button (100) may be installed on the second part (B2) and detachably coupled to the mount (200). More specifically, the button (100) may include a button body (101) that is installed to be in contact with the mount body (220) and has a second magnetic body (1014) detachably coupled to the first magnetic body (201) when in the first article state (BP1), and a coupler assembly (AS) that passes through the button body (101) and detachably coupled to the mount body (220). When the button (100) is coupled to the second part (B2), the second part (B2) may be positioned to be located between the button body (101) and the coupler assembly (AS). For example, when in the first article state (BP1), the button body (101) may be positioned to face the first part (B1).

[0048] The button body (101) may include a roughly disc-shaped body plate (1013) forming an outer shape and a button body groove (1011, 1012) formed through the body plate (1013).

[0049] The coupler assembly (AS) may include a first detachable plate (110) which is rotatably connected to a button body (101), and which includes a first detachable plate (110) that extends through a button body groove (1011, 1012) formed through the button body (101) so as to communicate with a mount groove (210) when the article (B) is in a first article state (BP1), and includes a coupling hook (111, 112) which is detachably coupled to a coupling pin (2111, 2121). For example, the coupling hook (111, 112) may include a hook body (1111a, 1121a) formed to protrude so as to be received in the mount groove (210) when in the first article state (BP1), and a coupling groove (1111b, 1121b) formed to be recessed in the hook body (1111a, 1121a) and provided to receive a coupling pin (2111, 2121). When the coupling pin (2111, 2121) is received in the coupling groove (1111b, 1121b), the coupling hook (111, 112) and the coupling pin (2111, 2121) can be coupled and fixed to each other. Through this, the mount (200) and the button (100) can be fixed to each other.

[0050] For example, the first detachable plate (110) may be rotatably provided. The position of the first detachable plate (110) in a state where the coupling pin (2111, 2121) is received in the aforementioned coupling groove (1111b, 1121b) may be defined as the first rotational position (RP1). And, the position of the first detachable plate (110) in a state where the coupling pin (2111, 2121) is detached from the coupling groove (1111b, 1121b) may be defined as the second rotational position (RP2). That is, the first detachable plate (110) may be provided to rotate between the first rotational position (RP1) and the second rotational position (RP2). Since the hook body (1111a, 1121a) of the first detachable plate (110) is received in the mount groove (210) of the mount (200), the rotation of the first detachable plate (110) can be limited to the radius in which the hook body (1111a, 1121a) moves within the mount groove (210).

[0051] The coupler assembly (AS) may include a second detachable plate (120) that is connected to the first detachable plate (110) and positioned between the first detachable plate (110) and the button body (101). The second detachable plate (120) may include a through groove (123, 124) that is positioned to communicate with the mount groove (210) and the button body groove (1011, 1012) when the article (B) is in the first article state (BP1) and is formed to allow the coupling hook (111, 112) to pass through.

[0052] The coupler assembly (AS) may include a third detachable plate (130) that is located on the opposite side of the second detachable plate (120) with respect to the first detachable plate (110) and covers the first detachable plate (110) and the second detachable plate (120).

[0053] The coupler assembly (AS) may include a handling plate (140) that is positioned on the outside of the third detachable plate (130) and passes through the third detachable plate (130) to be connected to the first detachable plate (110).

[0054] A detailed description of the first detachable plate (110), the second detachable plate (120), the third detachable plate (130), and the handling plate (140) will be provided later.

A pair of coupling projections (115) may be arranged symmetrically with respect to the center of the first plate body (113). A pair of coupling projections (115) may be formed to protrude from the first plate body (113) toward the center of the first plate opening (116). As will be described later, the coupling projection (115) may be connected to a handling rod (141, 142), thereby connecting the handling plate (140) and the first detachable plate (110) to each other. Thus, a user can grasp the externally exposed handling plate (140) and rotate it to rotate the first detachable plate (110) installed inside.

[0058] The first plate body (113) of the first detachable plate (110) may include a roughly annular ring shape, but is not limited thereto. A first plate opening (116) formed to penetrate the first plate body (113) may be disposed at the center of the first plate body (113).

[0059] The first detachable plate (110) may include a plate guide (114) that is formed protruding from the first plate body (113) and extends in a direction parallel to the direction in which the outer circumference of the first plate body (113) extends. The plate guide (114) may be received in the third detachable plate (130) to be described later and arranged to guide the rotation of the first detachable plate (110).

[0060] The second plate body (125) of the second detachable plate (120) may include a roughly annular ring shape, but is not limited thereto. A through groove (123, 124) may be formed in the second plate body (125), and the coupling hook (111, 112) of the first detachable plate (110) may pass through the through groove (123, 124). The coupling hook (111, 112) may be a pair of coupling hooks (111, 112), and may include a first coupling hook (111) and a second coupling hook (112) spaced apart from the first coupling hook (111). As described above, the coupling hook (111, 112) may pass through the through groove (123, 124) of the second detachable plate (120). In other words, the through grooves (123, 124) may include a first through groove (123) through which the first coupling hook (111) passes, and a second through groove (124) through which the second coupling hook (112) passes.

[0061] The lengths to which the first through-groove (123) and the second through-groove (124) extend may correspond to the lengths to which the first mount groove (211) or the second mount groove (212) extend, respectively, but are not limited thereto.

[0062] The third detachable plate (130) may include a third plate body (131) formed to cover the edge of the first detachable plate (110) and a third plate opening (132) formed to penetrate the third plate body (131) and communicate with the first plate opening (116).

The user can rotate the first detachable plate (110) by gripping and rotating the handling pin (143). Through this, the coupling grooves (1111b, 1121b) of the coupling hooks (111, 112) can be engaged / disengaged from the coupling pins (2111, 2121) of the mount (200). A detailed description thereof will be provided later.

[0064] When in the first article state (BP1), the button body grooves (1011, 1012) include a first button body groove (1011) positioned to communicate with the first mount groove (211) and a second button body groove (1012) positioned to communicate with the second mount groove (212), and the through grooves (123, 124) may include a first through groove (123) positioned to communicate with the first button body groove (1011) and a second through groove (124) positioned to communicate with the second button body groove (1012). As described above, the button body grooves (1011, 1012) may be formed to penetrate the button body (101) in the button body (101). Additionally, the through grooves (123, 124) may be formed to penetrate the second plate body (125) in the second detachable plate (120).

[0065] As described above, the first detachable plate (110) may include a coupling hook (111, 112) formed to protrude from the first plate body (113). The coupling hook (111, 112) may include a first hook body (1111a) positioned to pass through the first through-groove (123), the first button body groove (1011), and the first mount groove (211) when in the first article state (BP1), and a first coupling hook (111) including a first coupling groove (1111b) formed on one side of the first hook body (1111a), received in the first mount groove (211), and formed to be open toward the first coupling pin (2111) so as to be detachably coupled with the first coupling pin (2111). Additionally, the coupling hook (111, 112) may include a second hook body (1121a) positioned to pass through the second through-groove (124), the second button body groove (1012), and the second mount groove (212) when in the first article state (BP1), and a second coupling hook (112) including a second coupling groove (1121b) formed on one side of the second hook body (1121a), received in the second mount groove (212), and formed to be open toward the second coupling pin (2121) so as to be detachably coupled with the second coupling pin (2121).

[0066] The first detachable plate (110) may be rotatably provided between a first rotational position (RP1) in which a first coupling pin (2111) is inserted into a first coupling groove (1111b) and a second coupling pin (2121) is inserted into a second coupling groove (1121b), and a second rotational position (RP2) in which the first coupling groove (1111b) is separated from the first coupling pin (2111) and the second coupling groove (1121b) is separated from the second coupling pin (2121).

[0067] As described above, the first detachable plate (110) is connected to the handling plate (140), and the user can control the rotation of the first detachable plate (110) by operating the handling plate (140).

[0068] The handling rods (141, 142) may include a first handling rod (141) protruding from a part of the handling pin (143) to be coupled with one of a pair of coupling protrusions (115), and a second handling rod (142) protruding from another part of the handling pin (143) to be coupled with the other of the pair of coupling protrusions (115) and spaced apart from the first handling rod (141).

[0069] The first handling rod (141) can be connected to the first coupling projection (1151), and the second handling rod (142) can be connected to the second coupling projection (1152).

[0070] When the coupling projection (115) and the handling rod (141, 142) are connected to each other, the handling pin (143) may be rotatably arranged around the center of the third detachable plate (130) as an axis of rotation so as to be positioned parallel to the third plate body (131) to rotate the first detachable plate (110).

[0071] For example, the coupling hook (111, 112) may further include a first hook stopper (1111c) formed on one side of the first hook body (1111a) and a second hook stopper (1121c) formed on the other side of the second hook body (1121a), which is opposite to one side of the second hook body (1121a).

[0072] And, the second detachable plate (120) may include a second plate body (125) in which a through groove (123, 124) is formed, a first stop projection (121) formed protruding from a part of the second plate body (125) so as to be supported by contacting a first hook stopper (1111c) when the first detachable plate (110) is in a first rotational position (RP1), and a second stop projection (122) formed protruding from another part of the second plate body (125) so as to be supported by contacting a second hook stopper (1121c) when the first detachable plate (110) is in a second rotational position (RP2).

[0073] That is, the first hook stopper (1111c) and the first stop projection (121) can be arranged to be in contact with each other. Also, the second hook stopper (1121c) and the second stop projection (122) can be arranged to be in contact with each other. Through this, the rotation radius of the first detachable plate (110) can be limited.

[0074] Below, we examine the operation process of the safety coupler device (1) of the item.

[0075] When the first article state (BP1) is in which the second part (B2) of the article (B) is positioned to cover the first part (B1), the button (100) may be positioned to cover the mount (200). At this time, the first magnetic body (201) of the mount (200) may be connected to the second magnetic body (1014) of the button (100) and joined together. Through this, the mount (200) and the button (100) may be joined together in the first state. Also, when the first article state (BP1), the joining hooks (111, 112) may be inserted into the button body grooves (1011, 1012) and the mount groove (210). And, the joining grooves (1111b, 1121b) of the joining hooks (111, 112) may not receive the joining pins (2111, 2121). That is, in this case, the first detachable plate (110) may be in a state where it is located at the second rotational position (RP2).

[0076] Afterward, the user can grasp the handling pin (143) and rotate it. This allows the first detachable plate (110) to rotate and position the coupling grooves (1111b, 1121b) to receive the coupling pins (2111, 2121). This allows the first hook stopper (1111c) to be in contact with the first stop projection (121) and supported. That is, the first detachable plate (110) can be positioned at the first rotation position (RP1), thereby allowing the mount (200) and the button (100) to be secondarily coupled and more firmly connected.

[0077] For example, the user can resolve the primary and secondary couplings described above to separate the first part (B1) and the second part (B2). That is, the user can rotate the first detachable plate (110) by gripping and rotating the handling pin (143) so that the coupling grooves (1111b, 1121b) of the first detachable plate (110) do not receive the coupling pin (2111, 2121). In such a case, the first detachable plate (110) may be positioned at the second rotation position (RP2). For example, when the first detachable plate (110) is at the second rotation position (RP2), the second hook stopper (1121c) and the second stop projection (122) may be in contact and supported, but are not limited thereto. Afterward, the user can separate the first part (B1) and the second part (B2) by releasing the connection between the first magnetic body (201) and the second magnetic body (1014).

[0078] Specific embodiments have been illustrated and described above. However, the invention is not limited to the embodiments described above, and those skilled in the art may make various modifications without departing from the essence of the technical concept of the invention as described in the following claims.
