The second contact point (P2) may be a contact area between a portion of the third end (461) side of the second housing (460) and the second fastening member (420).

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

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

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 and withdrawing 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.

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).

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). When the locking unit (430) is unlocked, the user can adjust the length of the accessory device (401) by moving the second fastening member (420).

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 secure the first fastening member (410) and the second fastening member (420).

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). In addition, 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.

FIG. 7 is a rear view of an accessory device (401) according to one embodiment.

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

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

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 (e.g., the second end (442) of FIGS. 4a and 4b) of the first housing (440).

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., the X axis) of the first fastening member (410).

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).

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 pressurized region (455). The body region (453) may be fixedly arranged in the first housing (440). The body region (453) may be wound at least once. The pressurized region (455) may refer to a distal end of the elastic member (451) extending from an end of the body region (453). The pressurized region (455) may pressurize the second housing (460).

In one embodiment, the elastic member (451) can rotate the pressurized region (455) around the 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.

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

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.

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

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).

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

In one embodiment, the friction surface (445) may be provided between the first end (441) and the second end (442) in the first housing (440), and the friction surface (445) may face the 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).

For example, when the second housing (460) is in the first position (e.g., the position of the second housing (460) of FIGS. 11a and 11b), the friction surface (445) can come into 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) of FIGS. 12a and 12b), the friction surface (445) can come into contact with the second fastening member (420) only in a spaced area.

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 frictional force may also be increased as the force with which the second fastening member (420) presses the friction surface (445) increases. The friction surface (445) may limit the movement of the second fastening member (420) or fix the second fastening member (420).

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).

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.

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

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).

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) can release the movement restriction of the second fastening member (420) or reduce the frictional force restricting the movement, and the second fastening member (420) can move relatively freely.

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.

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.

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

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.

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).

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).

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.

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

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 extraction direction (e.g., +X direction). The friction member (447) in the bent state has an elastic force applied toward the 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 extraction direction.

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 area 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 pressurizing surface (465).

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 a plurality of directions, thereby supporting and fixing the second fastening member (420).

FIG. 10 is an exploded perspective view of an accessory device (401) according to one embodiment.

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).

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

In one embodiment, the protruding region (468) may be provided at the third end (461) of the second housing (460). The protruding region (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 region (468).

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).

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).

In one embodiment, the catch member (449) engages with the protruding area (468) and/or the catch groove (469), and can temporarily limit 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.

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.

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.

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 the 'state (S1) in which the first housing (440) and the second housing (460) are adjacent', or the 'state (S1) before the hinge unit (450) or the elastic member (451) is deformed'.

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 by referring 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 obviously impossible.

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).

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. If 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.

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 relatively restricted in its movement compared to the state (S1) where the second housing (460) is placed at the first position. The movement of the second fastening member (420) may be restricted, and the length of the accessory device (401) may be maintained in a fixed state.

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).

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).

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 engaging member (449) may be placed in a direction opposite to or spaced apart from the protruding area (468).

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.

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.

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

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 by referring 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 obviously impossible.

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.

For example, when the second fastening member (420) moves in the insertion direction (e.g., in the -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.

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.

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.

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

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 placed at the second position, compared to a state (S1) where the second housing (460) is placed at the first position, the first friction surface (445) and the friction member (447) may apply friction to the second fastening member (420) relatively weakly.

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).

In one embodiment, in a state (S2) where the second housing (460) is placed in the second position, the pressurizing surface (465) and the pressurizing member (467) may be spaced apart from the second fastening member (420) and may not pressurize the second fastening member (420).

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).

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 engaging member (449) can be inserted into the engaging groove (469) of the protruding area (468).

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 (e.g., the elastic member (451) of FIG. 7) of the hinge unit (450). 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).

In one embodiment, the user can move the second fastening member (420) to complete the length adjustment, and then push the second housing (460) to detach the engaging member (449) from the engaging groove (469). When the engaging member (449) is detached from the engaging 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.

FIG. 13 is a perspective view of an accessory device (401) according to one embodiment.

Referring to FIG. 13, a fixing member (427) according to one embodiment can prevent detachment of a second fastening member (420).

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

In one embodiment, the fixing member (427) may be formed to be caught by the loop (463), so that it may not pass through the loop (463). Alternatively, the fixing member (427) may be positioned only on one side of the loop (463). For example, the outer diameter of the fixing member (427) may be larger than the inner diameter of the loop (463). Alternatively, the fixing member (427) may be formed with a separate protruding structure (not shown), so that it may not pass through the inner diameter of the loop (463).

In one embodiment, one end of the first fastening member (410) is fixed to the first housing (440), and one end of the second fastening member (420) is arranged so as not to pass through one side of the loop (463), so that the first fastening member (410) and the second fastening member (420) can be fixed to the locking unit (430), and the first fastening member (410), the second fastening member (420), and the locking unit (430) may not be completely separated from each other.
