In the description with reference to the attached drawings, identical components are assigned the same reference numerals regardless of the drawing numbers, and redundant descriptions thereof will be omitted.

[0028] The various embodiments and terminology used herein are not intended to limit the technical features described in the present disclosure to specific embodiments, but should be understood to include various modifications, equivalents, or substitutes of the embodiments. In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more of the items, unless the context clearly indicates otherwise. In the present disclosure, each of the phrases "A or B," "at least one of A and B," "at least one of A or B," "A, B, or C," "at least one of A, B, and C," and "at least one of A, B, or C" can include any one of the items listed together in the corresponding phrase among the phrases, or all possible combinations thereof. Terms such as "first", "second", or "first" or "second" may be used merely to distinguish one component from another, and do not limit the components in any other respect (e.g., importance or order). When a component (e.g., a first component) is referred to as "coupled" or "connected" to another (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0029] The term "module" used in various embodiments may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0030] Various embodiments may be implemented as software (e.g., a program (120)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device). For example, a processor of the machine (e.g., an electronic device) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g. electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.

[0031] According to one embodiment, the method according to the various embodiments disclosed in the present disclosure may be provided as included in a computer program product. The computer program product may be traded as a product between a seller and a buyer.

[0104] Referring to FIG. 5, a locking unit (430) of an accessory device (401) according to one embodiment may include a first housing (440), a hinge unit (450), and a second housing (460).

[0105] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some components and structures of the accessory device (401) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the above-described embodiments may be combined with the accessory device (401) unless it is technically clearly impossible.

[0106] In one embodiment, the first housing (440) can be secured to the first fastening member (410) (e.g., the first fastening member (410) of FIGS. 4A and 4B). The first housing (440) can include a first end (441) on one side (e.g., in the -X direction) and a second end (442) on the other side opposite to the first end (441) (e.g., in the +X direction). The first end (441) of the first housing (440) can be connected to the first fastening member (410), and the second end (442) of the first housing (440) can be connected to a third end (461) of the second housing (460).

[0107] In one embodiment, the second housing (460) may be connected to the first housing (440) via a hinge unit (450). The second housing (460) may include a third end (461) on one side (e.g., in the -X direction), a fourth end (462) on the other side (e.g., in the +X direction) opposite to the third end (461), and a loop (463). The third end (461) of the second housing (460) may be connected to the second end (442) of the first housing (440). The loop (463) may refer to a through hole or open area provided between the third end (461) and the fourth end (462) to allow the second fastening member (420) to pass therethrough.

[0108] In one embodiment, the loop (463) may be configured to allow the second fastening member (420) to pass therethrough. For example, the loop (463) may be arranged so that the second fastening member (420) is movable in an insertion direction (e.g., -X direction) or an extraction direction (e.g., +X direction). Alternatively, the loop (463) may limit the range of movement of the second fastening member (420) and guide the movement of the first fastening member (410) and the second fastening member (420).

[0109] In one embodiment, the hinge unit (450) can connect the first housing (440) and the second housing (460). The hinge unit (450) can include a bracket or a mounting structure.

For example, the hinge unit (450) may urge the second housing (460) toward the first housing (440).

[0111] In one embodiment, at least one of the first housing (440) and the second housing (460) is movable between a first position and a second position (e.g., the position of the second housing (460) in FIGS. 12A and 12B) via a hinge unit (450).

[0112] For example, the first position may be a state or position of the locking unit (430) in which the first housing (440) and the second housing (460) are relatively closer than the second position, as illustrated in FIGS. 11a and 11b, which will be described later.

[0113] Additionally, for example, the second position may be a state or position of the locking unit (430) in which the first housing (440) and the second housing (460) are relatively spaced apart from each other compared to the first position, as illustrated in FIGS. 12a and 12b, which will be described later.

[0114] Hereinafter, the locking unit (430) and the accessory device (401) will be described based on an embodiment in which the second housing (460) moves relative to the first housing (440) with reference to the drawings, but this is merely an example for explanation. For example, even in cases in which the first housing (440) moves relative to the second housing (460), or both the first housing (440) and the second housing (460) move relative to each other, the locking unit (430) and the accessory device (401) of various embodiments of the present document can be applied identically or similarly.

[0115] In one embodiment, the hinge unit (450) may include an elastic member (e.g., an elastic member (451) of FIG. 7). An elastic force may be applied to the elastic member (451) in a preset direction, or a restoring force may be applied to the elastic member (451) when the elastic member (451) is deformed by an external force and then the external force is removed. The elastic member (451) may press the second housing (460) in a direction in which the fourth end (462) of the second housing (460) faces the first end (441) of the first housing (440).

[0116] In one embodiment of the present document, the hinge unit (450) can secure the second fastening member (420) by applying pressure to the first housing (440) and the second housing (460) in a direction in which they are adjacent to each other. In addition, at least one of the first housing (440) and the second housing (460) can be moved in a direction in which they are separated from each other by an external force (e.g., a user), thereby releasing the fixation of the second fastening member (420).

[0117] In one embodiment of the present document, the locking unit (430) may have a V-shaped structure in which the ends of the first housing (440) and the second housing (460) are connected with the hinge unit (450) as the center. The hinge unit (450) may support and / or fix the second fastening member (420) disposed between the first housing (440) and the second housing (460) by pressing the first housing (440) and the second housing (460) in a direction adjacent to each other.

[0118] In addition, the locking unit (430) according to one embodiment of the present document can provide convenience in fixing and releasing the accessory device (401) as well as adjusting the length of the accessory device (401). The length adjustment method is described with reference to FIG. 6.

[0119] In one embodiment, the second housing (460) may include a pressure surface (465). The pressure surface (465) may be formed on at least one surface facing the second fastening member (420). For example, the pressure surface (465) may be a surface facing the loop (463) or the second fastening member (420) at the fourth end (462). The pressure surface (465) may have a curved or protruding structure in at least a portion of the area.

[0120] In one embodiment, the pressure surface (465) is pressed in a direction facing the second fastening member (420) by the hinge unit (450) and can press the second fastening member (420). The pressure surface (465) can limit the movement of the second fastening member (420) or fix the second fastening member (420).

[0121] In one embodiment, the accessory device (401) can secure the first fastening member (410) and the second fastening member (420) or release the first fastening member (410) and the second fastening member (420) based on the position of the second housing (460).

[0122] For example, when the second housing (460) is in the first position, the pressing surface (465) can pressurize and support the second fastening member (420). Also, for example, when the second housing (460) is in the second position, the pressing surface (465) can not pressurize the second fastening member (420) or can reduce the pressing force, and the second fastening member (420) can move relatively freely.

[0123] In one embodiment, the fixing member (427) may include a magnetic material (428), and the first fastening member (410) may include a metallic material. For example, the first fastening member (410) may be made of a chain or mesh made of a metallic material.

[0124] In one embodiment, the magnetic body (428) can magnetically interact with the first fastening member (410). An attractive force can act between the magnetic body (428) and the first fastening member (410) in a direction that brings them closer to each other.

[0125] In one embodiment, the fixing member (427) can support the coupling of the first fastening member (410) and the second fastening member (420) together with the locking unit (430). The fixing member (427) can fix the body of the first fastening member (410) (e.g., the first body (413) of FIGS. 4A and 4B) and the end of the second fastening member (420) (e.g., the fourth connecting portion (422) of FIGS. 4A and 4B), and the locking unit (430) can fix the end of the first fastening member (410) (e.g., the first connecting portion (411) of FIGS. 4A and 4B) and the body of the second fastening member (420) (e.g., the second body (423) of FIGS. 4A and 4B).

[0126] In one embodiment of the present document, the fixing member (427) can support the first fastening member (410) and the second fastening member (420) so that they are not easily separated. For example, the user can first separate the fixing member (427) from the first fastening member (410) while the first fastening member (410) and the second fastening member (420) are fixed. Then, the user can change the position of the second housing (460) by pulling the second fastening member (420) upward (e.g., in the -Z direction) or in the withdrawal direction (e.g., in the +X direction), and unlock the locking unit (430).

[0127] FIG. 6 is a side view of an accessory device (401) according to one embodiment.

[0128] Referring to FIG. 6, the locking unit (430) of the accessory device (401) according to one embodiment may include at least two contact points (P1, P2) with the second fastening member (420).

[0129] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some components and structures of the accessory device (401) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the above-described embodiments may be combined with the accessory device (401) unless it is technically clearly impossible.

[0130] In one embodiment, when the second housing (460) is in a second position (e.g., the position of the second housing (460) in FIGS. 12A and 12B), the second housing (460) can contact the second fastening member (420) at at least two contact points (P1, P2).

[0131] In one embodiment, the at least two contact points (P1, P2) may include a first contact point (P1) and a second contact point (P2). The first contact point (P1) may be a contact area between a portion of the fourth end (462) of the second housing (460) and the second fastening member (420). The second contact point (P2) may be a contact area between a portion of the third end (461) of the second housing (460) and the second fastening member (420).

[0132] An accessory device (401) including a locking unit (430) according to one embodiment of the present document can provide the user with ease, convenience and / or intuitiveness of length adjustment of the accessory device (401) through a pressurizing mechanism at a first contact point (P1) and a second contact point (P2).

[0133] For example, to unlock the accessory device (401), the user may separate the securing member (427) from the first fastening member (410) and pull the securing member (427) upward (e.g., in the -Z direction) and / or in the withdrawing direction (e.g., in the +X direction). When the securing member (427) is pulled, the second fastening member (420) may press the first contact point (P1) and / or the second contact point (P2) of the locking unit (430).

[0134] In one embodiment, the second fastening member (420) can be restricted in the movement and pressing direction by the loop (463). For example, the second fastening member (420) can press the first contact point (P1) in an upward direction and an outward direction (e.g., +X direction), and when the first contact point (P1) is pressed, the second housing (460) can move from the first position to the second position.

[0135] In one embodiment, the second fastening member (420) can press the second contact point (P2) in a downward direction and an insertion direction (e.g., -X direction). The second contact point (P2) can serve as a support point. For example, the second fastening member (420) can support the second fastening member (420), thereby assisting the external force acting on the second fastening member (420) to be concentrated on the first fastening member (410), and the user can easily and conveniently move the second housing (460).

[0136] In one embodiment of the present document, the second fastening member (420) can overcome the elastic force of the hinge unit (450) and unlock the locking unit (430) by moving the second housing (460). Once the locking unit (430) is unlocked, the user can adjust the length of the accessory device (401) by moving the second fastening member (420).

[0137] In one embodiment, when the external force applied to the second fastening member (420) is removed, the pressure applied to the first contact point (P1) and the second contact point (P2) is also removed, and the second housing (460) can move to the first position by the elastic force of the hinge unit (450). When the second housing (460) moves to the first position, the locking unit (430) can press the second fastening member (420) and fix the first fastening member (410) and the second fastening member (420).

[0138] In one embodiment of the present document, the locking unit (430) can provide intuitiveness, convenience, and / or ease of length adjustment of the first fastening member (410) and the second fastening member (420). Furthermore, in one embodiment of the present document, the locking unit (430) can implement the above-described structure and operation without being limited to the thickness and material of the second fastening member (420), and the accessory device (401) including the locking unit (430) can have versatility and universality.

[0139] Figure 7 is a rear view of an accessory device (401) according to one embodiment.

[0140] Referring to FIG. 7, the hinge unit (450) of the accessory device (401) according to one embodiment may include an elastic member (451).

[0141] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some components and structures of the accessory device (401) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the above-described embodiments may be combined with the accessory device (401) unless it is technically clearly impossible.

[0142] In one embodiment, the hinge unit (450) may include a plurality of elastic members (451). The plurality of elastic members (451a, 451b) may be spaced apart from each other on opposite sides (e.g., in the + / -Y direction) of an end portion of the first housing (440) (e.g., the second end portion (442) of FIGS. 4a and 4b).

[0143] For example, the plurality of elastic members (451a, 451b) may include a first elastic member (451a) disposed at one end (e.g., an end in the +Y direction) of the first housing (440) and a second elastic member (451b) disposed at the other end (e.g., an end in the -Y direction) of the first housing (440). The first elastic member (451a) and the second elastic member (451b) may have a structure that is mutually symmetrical with respect to the longitudinal axis (e.g., an X axis) of the first fastening member (410).

[0144] In one embodiment of the present document, the first elastic member (451a) and the second elastic member (451b) are spaced apart from each other on both sides, so as to uniformly pressurize the second housing (460) and stably support the first housing (440) and the second housing (460).

[0145] In one embodiment, the elastic member (451) may have a spring structure. For example, the elastic member (451) may include a body region (453) and a pressure region (455). The body region (453) may be fixedly disposed in the first housing (440). The body region (453) may be wound at least once. The pressure region (455) may refer to a distal end of the elastic member (451) extending from an end of the body region (453). The pressure region (455) may pressurize the second housing (460).

[0146] In one embodiment, the elastic member (451) can rotate the pressurized region (455) about a rotational axis (e.g., Y-axis) by an external force while the body region (453) is fixed. The pressurized region (455) can rotate and provide torsion to the body region (453), and the body region (453) can store elastic force by torsion.

[0147] In one embodiment, when the external force acting on the pressurized area (455) is removed, the body area (453) can pressurize the pressurized area (455) in a direction that returns the pressurized area (455) to its original position (e.g., in a direction in which the fourth end (462) of the second housing (460) in FIGS. 4A and 4B faces the first end (441) of the first housing (440). The pressurized area (455) can pressurize the second housing (460), and the second housing (460) can be restored to its first position. In addition, the pressurized area (455) can pressurize the second housing (460) to pressurize and secure the second fastening member (420) (e.g., the second fastening member (420) in FIGS. 4A and 4B).

[0148] In one embodiment, the body region (453) can be wrapped at least once. Depending on the number of times the body region (453) is wrapped, the material of the body region (453), and / or the thickness of the body region (453), the elastic modulus of the body region (453) can be adjusted. For example, to enhance the fixing force of the second fastening member (420), the accessory device (401) can include a body region (453) having a greater thickness and / or being wrapped more times.

[0149] FIG. 8 is a side view of an accessory device (401) according to one embodiment.

[0150] Referring to FIG. 8, an accessory device (401) according to one embodiment may include at least a portion of a friction surface (445) and a friction member (447).

[0151] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some components and structures of the accessory device (401) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the above-described embodiments may be combined with the accessory device (401) unless it is technically clearly impossible.

[0152] In one embodiment, a friction surface (445) may be provided between a first end (441) and a second end (442) of a first housing (440), and the friction surface (445) may face a second fastening member (420). When the friction surface (445) and the second fastening member (420) come into contact, a frictional force may be applied between the friction surface (445) and the second fastening member (420).

[0153] For example, when the second housing (460) is in the first position (e.g., the position of the second housing (460) in FIGS. 11A and 11B), the friction surface (445) can be in contact with the second fastening member (420). For example, when the second housing (460) is in the second position (e.g., the position of the second housing (460) in FIGS. 12A and 12B), the friction surface (445) can be spaced apart from the second fastening member (420) or can be in contact only in at least a portion of the area.

[0154] In one embodiment, the second fastening member (420) may be pressed by the hinge unit (450) in a direction facing the friction surface (445). The stronger the force with which the second fastening member (420) presses the friction surface (445), the stronger the friction force may be. The friction surface (445) may restrict the movement of the second fastening member (420) or fix the second fastening member (420).

[0155] In one embodiment, the friction member (447) may be provided on the friction surface (445) of the first housing (440). Compared to the friction surface (445), the friction member (447) may have a relatively small area in contact with the second fastening member (420), and the strength of the pressure applied to the second fastening member (420) may be relatively large. The friction member (447) may stably limit and fix the movement of the second fastening member (420).

[0156] In one embodiment, the friction surface (445) may include a plurality of friction members (447), and the plurality of friction members (447) may be arranged in a direction from the first end (441) to the second end (442). As the second housing (460) moves from the first position to the second position, the number of friction members (447) among the plurality of friction members (447) that come into contact with the second fastening member (420) may decrease, and the frictional force acting on the second fastening member (420) may decrease. In addition, at least some of the friction members (447) may come into contact with the second fastening member (420) even when the second housing (460) is in the second position, thereby preventing the second fastening member (420) from slipping or quickly loosening and coming off.

[0157] In one embodiment, the accessory device (401) can secure the first fastening member (410) and the second fastening member (420) or release the first fastening member (410) and the second fastening member (420) based on the position of the second housing (460).

[0158] For example, when the second housing (460) is in the first position, at least one of the friction surface (445) and the friction member (447) can limit the movement of the second fastening member (420) and support the second fastening member (420).

[0159] For example, when the second housing (460) is in the second position, at least one of the friction surface (445) and the friction member (447) may release the movement restriction of the second fastening member (420) or reduce the frictional force that restricts the movement, and the second fastening member (420) may move relatively freely.

[0160] FIG. 9a is a perspective view of an accessory device (401) according to one embodiment, and FIG. 9b is a cross-sectional view of the accessory device (401) according to one embodiment.

[0161] Referring to FIGS. 9A and 9B, the accessory device (401) according to one embodiment may further include a pressure member (467), and further, the friction member (447) according to one embodiment may be made of an elastic material.

[0162] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some components and structures of the accessory device (401) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the above-described embodiments may be combined with the accessory device (401) unless it is technically clearly impossible.

[0163] In one embodiment, a pressure member (467) may be provided on a pressure surface (465) of a second housing (460). The pressure member (467) may be formed to protrude in a direction toward the second fastening member (420). The pressure member (467) may intensively pressurize one side (e.g., -Z direction) of the second fastening member (420) through the protruding structure.

[0164] In one embodiment, the pressure member (467) may be shaped to extend in a direction (e.g., the Y-axis direction) perpendicular to the direction in which the second fastening member (420) passes through the loop (463) (e.g., the X-axis direction). The pressure member (467) may contact the second fastening member (420) in a short-axis direction (e.g., the Y-axis direction) perpendicular to the longitudinal direction (e.g., the X-axis direction) of the second fastening member (420).

[0165] In one embodiment, the pressure member (467) has a shape extending in the short-axis direction, thereby increasing the contact area with the second fastening member (420) and / or effectively restricting movement of the second fastening member (420).

[0166] In one embodiment, when the second housing (460) is in the first position (e.g., the position of the first housing (440) of FIGS. 11A and 11B), the pressing member (467) can pressurize and support the second fastening member (420). Also, for example, when the second housing (460) is in the second position (e.g., the position of the second housing (460) of FIGS. 12A and 12B), the pressing member (467) can not pressurize the second fastening member (420) or can reduce the pressing force, allowing the second fastening member (420) to move relatively freely.

[0167] In one embodiment, the friction member (447) may be made of an elastic material. When pressed by the second fastening member (420), the friction member (447) may be bent and deformed in at least a portion of the area. The friction member (447) may have a shape extending from the first housing (440) in a direction facing the second fastening member (420).

[0168] In one embodiment, the friction member (447) can be deformed by being pressed by the second fastening member (420) when the second housing (460) is placed at the first position. For example, as illustrated in FIG. 9B, when the friction member (447) is pressed by the second fastening member (420) in a pressing direction (e.g., +Z direction), the distal end of the friction member (447) can be bent in the pressing direction and the pulling-out direction (e.g., +X direction). The bent friction member (447) has an elastic force applied toward its original position, and can press the second fastening member (420) in a direction opposite to the pressing direction (e.g., -Z direction) and in the insertion direction (e.g., -X direction). The friction member (447) can press and support the second fastening member (420) so that the second fastening member (420) does not move in the pulling-out direction.

[0169] In one embodiment, the first housing (440) may have a curved cross-section. For example, as illustrated in FIGS. 9A and 9B , the first housing (440) may have a shape in which the cross-section gradually decreases as it extends from the first end (441) to the second end (442), and the friction surface (445) disposed between the first end (441) and the second end (442) may be disposed to face the pressure surface (465).

[0170] In one embodiment, the pressing surface (465) and / or the pressing member (467) can press the second fastening member (420) in a pressing direction, and the friction surface (445) and / or the friction member (447) can press the second fastening member (420) in a direction opposite to the pressing direction and in a direction facing the pressing surface (465). At least some of the pressing surface (465), the pressing member (467), the friction surface (445), and the friction member (447) can stably press the second fastening member (420) in multiple directions, thereby supporting and fixing the second fastening member (420).

[0171] Figure 10 is an exploded perspective view of an accessory device (401) according to one embodiment.

[0172] Referring to FIG. 10, an accessory device (401) according to one embodiment may further include at least some of a guide rail (448), a catch member (449), a protruding area (468), and a catch groove (469).

[0173] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some components and structures of the accessory device (401) may be replaced, added, or omitted within a range easily understandable to those skilled in the art by referring to the drawings and descriptions below. In addition, at least one component or feature of the above-described embodiments may be combined with the accessory device (401) unless it is technically clearly impossible.

[0174] In one embodiment, the protruding area (468) may be provided at the third end (461) of the second housing (460). The protruding area (468) may be formed to protrude in a direction facing the second end (442) of the first housing (440). The guide rail (448) may be provided at the second end (442) of the first housing (440). The guide rail (448) may limit the range of movement of the protruding area (468).

[0175] For example, the guide rail (448) can accommodate the protruding area (468) and can have an extended shape so that the protruding area (468) can move within the range of movement of the second housing (460). By allowing the protruding area (468) to move only within the guide rail (448), the accessory device (401) can limit the range of movement of the second housing (460).

[0176] In one embodiment, the guide rail (448) may include a catch member (449). The catch member (449) may be positioned within a radius within which the protruding region (468) moves. The protruding region (468) may include a catch groove (469). The catch groove (469) may be a protruding structure for engaging the catch member (449).

[0177] In one embodiment, the catch member (449) engages with the protruding area (468) and / or the catch groove (469), and can temporarily restrict movement of the protruding area (468) while the second housing (460) is positioned at the second position, and can support the second housing (460) at the second position. The catch groove (469) and the catch member (449) are described with reference to FIGS. 11A, 11B, 12A, and 12B.

[0178] FIG. 11a is a perspective view of an accessory device (401) according to one embodiment, and FIG. 11b is a cross-sectional view of a locking unit (430) according to one embodiment.

[0179] Referring to FIGS. 11A and 11B, an accessory device (401) according to one embodiment can secure a first fastening member (410) and a second fastening member (420) in a state (S1) where a second housing (460) is placed in a first position.

[0180] Hereinafter, with reference to FIGS. 11A and 11B, the accessory device (401) and the locking unit (430) in a state (S1) in which the second housing (460) is arranged at the first position will be described. However, the state (S1) in which the second housing (460) is arranged at the first position is merely an exemplary expression, and this may be replaced with a state (S1) in which the first housing (440) and the second housing (460) are adjacent to each other, or a state (S1) before the hinge unit (450) or the elastic member (451) is deformed.

[0181] In addition, in the following, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some configurations and structures may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art with reference to the drawings and descriptions below in the locking unit (430) and the accessory device (401) including the same. In addition, at least one configuration or feature of the embodiments described above may be combined in the locking unit (430) and the accessory device (401) including the same, unless it is technically clearly impossible.

[0182] In one embodiment, in a state (S1) where the second housing (460) is placed at the first position, the second fastening member (420) may be restricted from moving in both directions (e.g., + / - X direction). The second fastening member (420) may be fixed to the first fastening member (410) and / or the locking unit (430).

[0183] In one embodiment, in a state (S1) where the second housing (460) is arranged at the first position, at least some of the pressing surface (465), the pressing member (467), the friction surface (445), and the friction member (447) can press the second fastening member (420), or can press the second fastening member (420) relatively strongly. When the movement of the second fastening member (420) is restricted or the second fastening member (420) is fixed, the length of the accessory device (401) can be maintained in a fixed state.

[0184] In one embodiment, in a state (S1) where the second housing (460) is disposed at the first position, the movement of the second fastening member (420) may be relatively limited compared to the state (S1) where the second housing (460) is disposed at the first position. The movement of the second fastening member (420) may be limited, and the length of the accessory device (401) may be maintained in a fixed state.

[0185] In one embodiment, at least some of the pressure surface (465), the pressure member (467), the friction surface (445), and the friction member (447) can restrict the movement of the second fastening member (420). For example, in a state (S1) where the second housing (460) is disposed at the first position, compared to a state (S2) where the second housing (460) is disposed at the second position, at least some of the pressure surface (465), the pressure member (467), the friction surface (445), and the friction member (447) can relatively strongly press the second fastening member (420).

[0186] In one embodiment of the present document, at least some of the pressure surface (465), the pressure member (467), the friction surface (445), and the friction member (447) can limit the movement of the second fastening member (420) and fix the second fastening member (420). By placing the second housing (460) at the first position and fixing the second fastening member (420), the user can easily and conveniently fix the second fastening member (420) and / or intuitively and stably fix the length of the accessory device (401).

[0187] In one embodiment, in a state (S1) where the second housing (460) is placed in the first position, the protruding area (468) may be placed within the guide rail (448). The catch member (449) may be placed in a direction opposite to or spaced apart from the protruding area (468).

[0188] FIG. 12a is a perspective view of an accessory device (401) according to one embodiment, and FIG. 12b is a cross-sectional view of a locking unit (430) according to one embodiment.

[0189] Referring to FIGS. 12a and 12b, an accessory device (401) according to one embodiment can release the fixation of the first fastening member (410) and the second fastening member (420) in a state (S2) where the second housing (460) is placed in the second position.

[0190] Hereinafter, with reference to FIGS. 12a and 12b, the accessory device (401) and the locking unit (430) in a state (S2) where the second housing (460) is arranged at the second position will be described. However, the state (S2) where the second housing (460) is arranged at the second position is merely an exemplary expression, and this may be replaced with a state (S2) where the first housing (440) and the second housing (460) are spaced apart from each other, or a state (S2) where the hinge unit (450) or the elastic member (451) is deformed.

[0191] In addition, in the following, any content that overlaps with the above-described content will be omitted for explanation, and it is to be understood that some configurations and structures may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art with reference to the drawings and descriptions below in the locking unit (430) and the accessory device (401) including the same. In addition, at least one configuration or feature of the embodiments described above may be combined in the locking unit (430) and the accessory device (401) including the same, unless it is technically clearly impossible.

[0192] In one embodiment, in a state (S2) where the second housing (460) is placed at the second position, the second fastening member (420) can move in both directions (e.g., + / - X direction). The second fastening member (420) can be inserted or withdrawn into the loop (463), and the fixation of the first fastening member (410) and the second fastening member (420) can be released, or the fixation positions can be changed.

[0193] For example, when the second fastening member (420) moves in the insertion direction (e.g., -X direction), the overlapping length of the first fastening member (410) and the second fastening member (420) may increase, and the length of the accessory device (401) may decrease.

[0194] For example, when the second fastening member (420) moves in the withdrawal direction (e.g., +X direction), the overlapping length of the first fastening member (410) and the second fastening member (420) may be shortened, and the length of the accessory device (401) may be lengthened.

[0195] In one embodiment, in a state (S2) where the second housing (460) is placed at the second position, at least some of the pressing surface (465), the pressing member (467), the friction surface (445) and the friction member (447) may not press the second fastening member (420) or may press the second fastening member (420) relatively weakly.

[0196] In one embodiment, in a state (S2) where the second housing (460) is positioned at the second position, the second fastening member (420) can move relatively freely compared to a state (S1) where the second housing (460) is positioned at the first position. The second fastening member (420) can change position relatively freely, and the length of the accessory device (401) can be adjusted.

[0197] In one embodiment, at least some of the friction surface (445) and the friction member (447) may limit the movement of the second fastening member (420). For example, in a state (S2) where the second housing (460) is positioned at the second position, compared to a state (S1) where the second housing (460) is positioned at the first position, the first friction surface (445) and the friction member (447) may exert relatively weak friction on the second fastening member (420).

[0198] In one embodiment, at least some of the friction surface (445) and the friction member (447) can limit movement of the second fastening member (420), the locking unit (430) can prevent the second fastening member (420) from moving quickly, the accessory device (401) can prevent the locking unit (430) from being pushed back or disengaged, and / or the user can smoothly and intuitively adjust the length of the accessory device (401).

[0199] In one embodiment, in a state (S2) where the second housing (460) is placed at the second position, the pressing surface (465) and the pressing member (467) may be spaced apart from the second fastening member (420) so as not to press the second fastening member (420).

[0200] In one embodiment of the present document, a user can easily and conveniently release the fixation of the accessory device (401) or adjust the length of the accessory device (401) by placing the second housing (460) at the second position and changing the position of the second fastening member (420).

[0201] In one embodiment, in a state (S2) where the second housing (460) is placed at the second position, the protruding area (468) can be placed within the guide rail (448), and the catch member (449) can be inserted into the catch groove (469) of the protruding area (468).

[0202] In one embodiment, the engaging member (449) can engage with the engaging groove (469) and support the second housing (460). The second housing (460) at the second position can be pressed toward the first housing (440) by an elastic member of the hinge unit (450) (e.g., the elastic member (451) of FIG. 7). As the second housing (460) is pressed, the second fastening member (420) can be pressed and the movement of the second fastening member (420) can be restricted. The engaging member (449) can engage with the engaging groove (469) and support an elastic force applied from the elastic member (451), and the second fastening member (420) can smoothly move within the loop (463).

[0203] In one embodiment, when the user moves the second fastening member (420) to complete the length adjustment, the user can push the second housing (460) to detach the locking member (449) from the locking groove (469). When the locking member (449) is detached from the locking groove (469), the second housing (460) can be moved to the first position by the elastic member (451). Accordingly, the accessory device (401) can conveniently and intuitively adjust the length.

[0204] Fig. 13 is a perspective view of an accessory device (401) according to one embodiment.

[0205] Referring to FIG. 13, a fixing member (427) according to one embodiment can prevent the second fastening member (420) from being detached.
