Description

Technology Field

[0001] The present invention relates to a sliding device, and more specifically, to a sliding device in which the movable structure can be easily removed from a fixed part. Background Technology

[0003] A sliding device is a mechanism in which a pair of members are movably connected to each other, and it can be widely used in modular home appliances such as TVs, monitors, consoles, refrigerators / freezers, and air purifiers. Since one of the members is fixed to the floor or wall and the other is fixed to the appliance, the position of the appliance can be easily changed. This sliding device can be moved to a desired position and then fixed in place; when installing a display panel in a wall-mounted manner, the position of the display panel can be easily moved, eliminating the need for a worker to perform cumbersome tasks such as disassembly and reassembly.

[0004] In addition, sliding devices can be installed in vehicles for the convenience of passengers, and in particular, they can be applied to vehicle seat sliding devices. Seats are designed to allow for position adjustment according to the passenger's physique, preferences, situation, or needs. Among these, vehicle seat sliding devices are widely used to adjust the forward and backward positions of the seat.

[0005] This vehicle seat sliding device can be installed so that it normally remains locked in a specific position, but when a user selectively operates a control device such as a lever, button, or switch, the locked state is released, allowing it to slide along a rail. Subsequently, the user can fix the seat in a desired position by sliding the seat and then operating the control device again to lock it in the selected position.

[0006] As such, the sliding device enables movable structures, such as home appliances or seats, to be movably installed on fixed parts such as walls, floors, or vehicle bodies, and allows the movable structures to be attached to or detached from the fixed parts when necessary. In other words, the sliding device is provided such that a pair of members can be movably coupled or separated, and the movable structures can be attached to or removed from the fixed parts.

[0007] Figure 1 is a side view of a seat schematically showing the location where a sliding rail is installed in a removable seat.

[0008] The above sliding rail (3) is composed of a fixed rail (3a) fixed toward the locking device (1) at the bottom of the seat and a transfer rail (3b) fixed toward the cushion frame (2), and the transfer rail (3b) is configured to move in the forward and backward directions while sliding along the fixed rail (3a).

[0009] In addition, a locking system (not shown) is provided as a means to restrict the movement of the transfer rail (3b), and when the handle part (4) protruding forward of the seat is operated, the locking state of the locking system is released, allowing the transfer rail (3b) to move back and forth.

[0010] Meanwhile, in the case of multi-purpose vehicles, it is desirable to allow for more diverse adjustments to the position and mounting configuration of the seats compared to standard passenger vehicles in order to further enhance the utilization of interior space.

[0011] For example, conventionally, adjustment of the seat's forward and backward position was required simply to maintain a comfortable posture according to the occupant's physical condition, but recent multi-purpose vehicles require a seat removal device to increase space utilization.

[0012] In addition, as a vehicle seat having folding and detachable functions, Korean Patent Application No. 2002-0044417 presents a detachable seat capable of automatic tumble using a spiral spring and a two-point fixing structure. This detachable seat is configured such that front lock plates are installed on both sides of the front end of the seat frame to which the vehicle seat is fixed, and rear lock plates are installed on both sides of the rear end, and a lock plate link is installed to connect the front and rear lock plates. A long sliding rail connected to the front and rear lock plates is installed to be slidable on a long sliding channel fixed to the vehicle body frame, while a locking device for restricting and releasing the sliding movement of the long sliding rail is provided on the long sliding rail.

[0013] However, conventional sliding devices lacked a configuration to maintain the unlocked state when unlocking the rails for sliding, so there was a problem that caused inconvenience to the user, as they had to continuously pull the unlocking lever while sliding.

[0014] Similarly, there was a problem that caused inconvenience to the user because when removing and reattaching the member attached to the movable structure from the fixed side of the sliding device, the user had to pull a lever to reattach it.

[0015] Furthermore, although the sliding device requires the movable structure to slide and be fixed at the user's desired position, there were problems such as poor fastening force relative to weight, excessive play between parts during locking, and movement in the sliding direction of the movable structure even when locked. Consequently, this resulted in low product reliability and caused inconvenience to users.

[0016] In addition, conventional detachable sliding devices did not disclose a structure that supports the sliding of a moving structure in a direction perpendicular to the sliding direction during sliding, which caused movement between products during sliding and resulted in inconvenience to the user.

[0017] In particular, conventional sliding devices had the problem that the roller rolling on the ground and the roller supporting the rail were different when the seat was removed, which increased the number of parts and the weight.

[0018] Furthermore, conventional sliding devices had the problem of not being able to provide convenience to the user because the fixed part and the movable structure were not electrically connected. In particular, there is a recent trend of incorporating additional functions such as heating and charging into vehicle seats and consoles, and since home appliances require power and signal connections to the fixed part for operation, a structure capable of electrically connecting the fixed part and the movable structure is required. The problem to be solved

[0020] The problem that the present invention aims to solve is to provide a sliding device that solves the problems of the aforementioned prior art. Specifically, it provides a sliding device in which a movable structure can be detached from a fixed part and the structure of the locking unit and the detachment unit is simple.

[0021] In addition, the purpose is to provide a sliding device that is convenient to use, as the locking unit and the detachment unit remain in an unlocked state with only a single operation of the lever, making it easy to detach the movable structure, and eliminating the need for separate operation when reattaching the movable structure to the fixed part.

[0022] In addition, the purpose is to provide a sliding device with high fastening and supporting forces relative to weight by having a structure that supports each other when the detachable unit is fastened and unfastened, and in particular, excellent coupling stability by applying an anti-loosening structure when the detachable unit is fastened to the lower rail.

[0084] As illustrated in these drawings, the sliding device (10) according to an embodiment of the present invention comprises a lower rail (100) mounted on a fixed part (20), a moving bracket (200) mounted on a moving structure (30) and installed to slide back and forth on the lower rail (100), and at least one detachable unit (500) installed on the moving bracket (200) and restrained to the lower rail (100), which is released from restraint on the lower rail (100) when operated, and the detachable unit (500) can be operated according to the operation of a detachable lever (31) to maintain a state of being released from restraint.

[0085] The sliding device (10) is a device for installing a movable structure (30) so as to be slidably installed on a fixed surface (21) of a fixed part (20), and may be configured to include a movable bracket (200) and a lower rail (100). Additionally, the sliding device (10) may be configured to include at least one of a sliding unit (300), a locking unit (400), a detachable unit (500), a connecting unit (600), and a power unit (700) so that the movable structure (30) is mounted on the fixed part (20) and slides, and can be used by adjusting its position according to the user's convenience, or can be removed from the fixed part (20) and placed in another location or moved along the ground.

[0086] The movable structure (30) may be a modular home appliance such as a TV, monitor, refrigerator / freezer, or air purifier, or a seat, console, etc. that is mounted on a vehicle.

[0087] This moving structure (30) may be equipped with a detachment lever (31) that simultaneously operates the detachment unit (500) and the locking unit (400), and a locking release lever (33) that operates only the locking unit (400).

[0088] When the detachment lever (31) is operated, the detachment unit (500) and the locking unit (400) are simultaneously released from the lower rail (100), and additionally, the power unit (700) is also released from the lower rail (100), so that the movable structure (30) can be removed from the fixed part (20). That is, the movable bracket (200) can be separated from the lower rail (100).

[0089] This detachable lever (31) is provided with a detachable operating part (31a) that presses the connecting unit (600) on the opposite side of the operating part. Additionally, it is provided with a detachable lever elastic member (32) that elastically deforms when the detachable lever (31) is operated to press the connecting unit (600), and the detachable lever elastic member (32) is restored when the operating force is removed and returns the detachable lever (31) to its original position.

[0090] For example, as shown in FIGS. 2 and 3, if the moving structure (30) is a seat installed in a vehicle, the detachment lever (31) is placed in a position that is less accessible because it is used relatively infrequently, and the operating part can be placed on the rear side of the seat by protruding to the rear of the vehicle.

[0091] When the locking release lever (33) is operated, only the locking unit (400) is released from the restraint with the lower rail (100), and additionally, the power unit (700) is also released from the restraint with the lower rail (100), so the moving structure (30) can slide. That is, when the locking release lever (33) is operated, the moving bracket (200) can move in the forward and backward directions on the lower rail (100).

[0092] This locking release lever (33) is provided with a locking release action part (33a) that presses the locking unit (400) on the opposite side of the operating part. Additionally, it is provided with a locking release lever elastic member (34) that elastically deforms when the locking release lever (33) is operated to press the locking unit (400), and the locking release lever elastic member (34) is restored when the operating force is removed and returns the locking release lever (33) to its original position.

[0093] For example, as shown in FIGS. 2 and 3, if the movable structure (30) is a seat installed in a vehicle, the locking release lever (33) is positioned in an accessible location because it is used relatively frequently by the user, and the operating part can be positioned at the front of the seat by protruding forward of the vehicle.

[0094] The fixed part (20) may be a ground or wall on which a home appliance is mounted, or a car body or floor of which a seat or console is mounted.

[0095] A movable bracket (200) is mounted on a movable structure (30), and as shown in FIG. 4, a bracket power supply unit (710) of a sliding unit (300), a locking unit (400), a detachable unit (500), a connecting unit (600), and a power unit (700) can be installed so as to be operable. At least a portion of this movable bracket (200) is inserted into the opening (110) of the lower rail (100) with a gap, and can be formed to be elongated along the sliding direction.

[0096] For example, the movable bracket (200) may be formed in a shape that is spaced apart from two plates with a gap between them and connected therebetween, and at least a portion of the bracket power section (710) of the sliding unit (300), locking unit (400), detachable unit (500), connecting unit (600), and power unit (700) may be disposed between the two plates.

[0098] The lower rail (100) is mounted on the fixed part (20) and is formed to be long along the sliding direction. The lower rail (100) consists of a pair and is spaced apart from each other in a direction perpendicular to the sliding direction. Below, for convenience of explanation, the direction in which the fixed part (20) slides along the lower rail (100) is described as the front-back direction, the direction in which the fixed part (20) is positioned relative to the lower rail (100) is described as the lower side, and the opposite direction is described as the upper side. Additionally, the direction in which the pair of lower rails (100) are spaced apart relative to the lower rail (100) is described as the left-right direction.

[0099] The lower rail (100) is formed in the shape of a hollow square column with one side cut off, and is mounted with the lower wall portion (140) in close contact with the fixed portion (20). At this time, the lower rail (100) may be mounted to the fixed portion (20) through fastening members such as bolts or screws, but is not limited thereto.

[0100] And, the lower rail (100) has an inner wall (120) and an outer wall (130) perpendicular to the lower wall (140) that is in close contact with the fixed part (20), and has an opening (110) into which at least a part of the movable bracket (200) is inserted between the upper end of the inner wall (120) and the outer wall (130).

[0101] Referring to FIG. 5, the lower rail (100) has an inner wall portion (120) and an outer wall portion (130) facing each other with an opening (110) into which at least a portion of the movable bracket (200) is inserted.

[0102] The inner wall portion (120) forms one wall portion perpendicular to the fixed surface (21) of the lower rail (100) and can be positioned on the opposite side between a pair of lower rails (100).

[0103] A detachable unit (500), to be described later, may be attached to this inner wall portion (120). The inner wall portion (120) may be formed with an upper end protruding toward the outer wall portion (130) and may be provided with a detachable portion (121) to which the detachable unit (500) is attached.

[0104] This detachable part (121) is positioned to face the lower side wall (140) of the lower rail (100) and may be provided with a seating groove (123) formed by being recessed on the facing surface. The seating groove (123) is provided at a position spaced apart from the protruding end surface of the detachable part (121). The protruding end of the detachable part (121) engages with the detachable unit (500), and at least a portion of the rail catch (510) is inserted into and supported in the seating groove (123). As the seating groove (123) is formed in the detachable part (121), the rail catch (510) is further dug into the inside of the detachable part (121) and secured, thereby supporting the rail catch (510) so that it does not easily come loose or deform when an external force, such as a collision, is applied to the sliding device (10).

[0105] Additionally, the detachable part (121) may have a slide surface (125) connected to the upper surface at the protruding end surface, and the slide surface (125) may be formed as an inclined surface or a curved surface so as to support the sliding unit (300) to be described later.

[0106] Additionally, the inner wall portion (120) is formed to be thicker than the outer wall portion (130) to ensure rigidity. Furthermore, the inner wall portion (120) may be formed at an angle such that the thickness of the inner wall portion (120) increases as the surface facing the outer wall portion (130) moves toward the lower wall portion (140) of the rail (100).

[0108] The outer wall portion (130) forms a wall portion perpendicular to the fixed surface (21) of the lower rail (100) and can be positioned on the opposite side of the facing side between a pair of lower rails (100).

[0109] A locking unit (400), which will be described later, can be attached to this outer wall portion (130). A locking hole (137) into which the locking unit (400) is attached is formed in the outer wall portion (130). The locking hole (137) is formed in the shape of a roughly rectangular hole and is formed by penetrating from the inner side facing the inner wall portion (120) of the outer wall portion (130) to the outer side of the lower rail (100). Accordingly, the locking unit (400) has a front side and a rear side facing each other, spaced apart in the sliding direction of the locking hole (137), and an upper side and a lower side facing each other, spaced apart in the vertical direction. And, a locking unit (400) is fastened to the locking hole (137), and the locking unit (400) is fastened by hooking it to the upper side of the locking hole (137), and the locking unit (400) is fastened by fitting it to the front side and the rear side, respectively. A plurality of such locking holes (137) are formed on the lower rail (100) at equal intervals along the sliding direction.

[0110] In addition, the locking hole (137) can be used to insert not only the locking unit (400) but also the bracket power supply (710) of the power unit (700) described later.

[0111] Additionally, the outer wall portion (130) may be provided with a flange portion (131) and a protrusion portion (135) so that an insulating cover (733), which will be described later, is installed facing the outer surface, which is the opposite side of the inner wall portion (120) of the outer wall portion (130).

[0112] The flange portion (131) and the protrusion (135) are formed by protruding from the outer surface of the outer wall portion (130). The flange portion (131) is provided on the upper side of the outer wall portion (130), and the upper end of the outer wall portion (130) may be formed by extending along the fixed surface (21). This flange portion (131) may be provided with a fixing rib (132) formed by protruding one side toward the fixed surface (21). The fixing rib (132) is provided spaced apart from the outer wall portion (130) and has a fitting portion (133) in which one side of the insulating cover (733) is fitted and fastened between the outer wall portion (130) and the fixing rib (132).

[0113] A protrusion (135) is provided on the lower side of the outer wall portion (130), and the lower portion of the outer surface of the outer wall portion (130) is formed to protrude along the fixing surface (21) and is in close contact with the fixing portion (20) and is positioned to face the flange portion (131). This protrusion (135) may have an insertion groove (136) formed by being recessed on the surface facing the flange portion (131). The insertion groove (136) is provided spaced apart from the outer wall portion (130) and is formed at a position facing the fitting portion (133), so that the other side of the insulating cover (733) is fitted and fastened. Additionally, the insertion groove (136) may be formed with a circular cross-section, and the opening into which the other side of the insulating cover (733) is inserted is formed smaller than the diameter of the insertion groove (136) so that the other side of the insulating cover (733) is not detached from the insertion groove (136) after being fitted and fastened.

[0114] The opening (110) refers to the space between the protruding end of the detachable part (121) and the outer wall part (130), and at least a portion of the movable bracket (200) is inserted therein.

[0116] Meanwhile, below, the locking unit (400) will be described with reference to FIGS. 6 to 9.

[0117] The locking unit (400) is installed on the movable bracket (200) and is fastened to the locking hole (137) formed in the lower rail (100). When operated, it is released from the locking hole (137), and the locking unit (400) operates when the detachment lever (31) or the locking release lever (33) is operated. However, to remove the movable bracket (200) from the lower rail (100), the detachment lever (31) only needs to be pressed or pulled once, and the locking unit (400) operates according to the operation of the detachment lever (31) and maintains the operated state. Then, when adjusting the position by sliding the movable bracket (200) along the lower rail (100), the locking unit (400) is released from the lower rail (100) by pressing or pulling the locking release lever (33). At this time, the movable bracket (200) can be slid while maintaining the state of pressing or pulling the locking release lever (33). After that, when the operating force applied to the locking release lever (33) is removed, the locking unit (400) is secured to the lower rail (100) and fixed in position.

[0118] This locking unit (400) is operably installed on a moving bracket (200) and is configured to include a track rocker (410), a first rocker (430), and a second rocker (450).

[0119] The track rocker (410) is rotatably installed on the movable bracket (200) via at least one connecting shaft (470).

[0120] The connecting shaft (470) can be fixed by being coupled to the movable bracket (200) and is formed long along the sliding direction, having an axis parallel to the sliding direction. This connecting shaft (470) can be provided as a single unit, or if provided as multiple units, they can have the same axis and be spaced apart in the axial direction.

[0121] The track rocker (410) can be rotatably installed on the connecting shaft (470).

[0122] And, when the track rocker (410) is operated to be released from the locking hole (137), a track rocker elastic member (401) is provided that elastically deforms to elastically support the track rocker (410), and the track rocker elastic member (401) is restored when the operating force is removed and returns the track rocker (410) to its original position.

[0123] This track rocker (410) is provided with a track rocker body (411) that is formed lengthwise along the sliding direction, and the track rocker body (411) may be formed in a plate shape that is inclined with respect to, for example, the fixed surface (21).

[0124] This track rocker body (411) may be provided with a locking release operating part (412) that is formed by protruding a portion from the side of the outer wall part (130). As shown in FIG. 3, the locking release operating part (412) is positioned to be pressed against the locking release operating part (33a) when the locking release lever (33) is operated, and as shown in FIG. 6, it is positioned to be pressed against the pressing piece (650) to be described later when the detachment lever (31) is operated.

[0125] Additionally, the track rocker (410) is provided with track rocker fastening portions (415) at each end of the track rocker body (411) in the sliding direction. The track rocker fastening portions (415) are provided at both ends of the track rocker body (411) and are formed long along a direction intersecting the sliding direction, passing through the opening (110) of the lower rail (100). These track rocker fastening portions (415) can be formed by bending and extending both ends of the track rocker body (411) at a right angle. The upper end of the track rocker fastening portion (415) is formed integrally with the track rocker body (411), and the lower end is provided with a track rocker projection (416) that is fastened to a locking hole (137).

[0126] The track rocker projection (416) is formed to protrude from the track rocker fastening portion (415) toward the outer wall portion (130) and may consist of a fastening surface (417) formed with a step difference from the track rocker fastening portion (415) and a fastening inclined surface formed such that the thickness narrows toward the end. The track rocker projection (416) is fastened to the locking hole (137) and the fastening surface (418) supports the upper surface of the locking hole (137).

[0127] When the locking release operating part (412) of this structure is pressed, the track rocker (410) rotates around the axis of the connecting shaft (470) and operates so that the track rocker projection (416) is released from the locking hole (137). Then, when the operating force pressing the locking release operating part (412) is removed, it rotates back to its original position by the restoring force of the track rocker elastic member (401) and the track rocker projection (416) is secured to the locking hole (137).

[0129] The first rocker (430) and the second rocker (450) are each rotatably installed on the movable bracket (200) via at least one connecting shaft (470). The first rocker (430) and the second rocker (450) are rotatably installed on the connecting shaft (470) and are spaced apart from each other along the axial direction of the connecting shaft (470), and can be positioned between the track rocker fastening portions (415). These first rocker (430) and the second rocker (450) each have a plurality of first rocker protrusions (432) and a plurality of second rocker protrusions (452) that are fastened to the locking hole (137).

[0130] The first rocker (430) and the second rocker (450) each include a first rocker body (431) and a second rocker body (451) that are formed lengthwise along a direction intersecting the sliding direction and pass through the opening (110) of the lower rail (100).

[0131] The first rocker body (431) and the second rocker body (451) each have their upper ends rotatably connected to a connecting shaft (470), and each have a plurality of first rocker protrusions (432) and a plurality of second rocker protrusions (452) on their lower ends.

[0132] In addition, a first rocker elastic member (402) and a second rocker elastic member (403) are provided, which elastically deform and elastically support the first rocker (430) and the second rocker (450) respectively when the first rocker (430) and the second rocker (450) are operated to be released from the locking hole (137). The first rocker elastic member (402) and the second rocker elastic member (403) are restored when the operating force is removed and return the first rocker (430) and the second rocker (450) respectively to their original positions.

[0133] The first rocker projection (432) and the second rocker projection (452) are each provided in multiple numbers on the first rocker body (431) and the second rocker body (451), respectively, spaced apart by the spacing of the locking hole (137) along the sliding direction, and as shown in the drawing, they may be provided in four numbers, but are not limited thereto.

[0134] As shown in FIG. 8, the locking unit (400) of this structure has a track rocker projection (416), a first rocker projection (432), and a second rocker projection (452) fastened to the locking hole (137). The track rocker (410) is provided to prevent the movable bracket (200) from moving up and down on the lower rail (100), and the first rocker (430) and the second rocker (450) are provided to prevent the movable bracket (200) from moving in a sliding direction along the lower rail (100) when fastened.

[0135] The track rocker projection (416) has a connecting surface (417) that supports the upper side of the locking hole (137) and is spaced apart from the locking hole (137) in the sliding direction. That is, the track rocker projection (416) is spaced apart from the front and rear sides of the locking hole (137) so that it can be connected even if there is play in the sliding direction with the locking hole (137), and is provided to be easily connected to the locking hole (137) compared to the first rocker (430) and the second rocker (450).

[0136] The first rocker projection (432) and the second rocker projection (452) are fitted into the locking hole (137) in a sliding direction. That is, the first rocker projection (432) can be fitted into the front surface of the locking hole (137), and the second rocker projection (452) can be fitted into the rear surface of the locking hole (137). However, the first rocker projection (432) and the second rocker projection (452) can be spaced apart from the upper surface of the locking hole (137) while in a state where they are fitted into the locking hole (137).

[0137] Specifically, the first rocker projection (432) and the second rocker projection (452) are formed such that their width in the front-rear direction narrows as they approach the ends. The first rocker projection (432) has a front guide surface (433) formed to support the front surface, and the second rocker projection (452) has a front guide surface (433) formed to support the rear surface.

[0138] Additionally, the first rocker projection (432) is formed with a front guide surface (433) on the front surface and a first auxiliary guide surface (434) on the rear surface so that it can be easily inserted into the locking hole (137), and is formed so that the sliding direction width becomes narrower toward the end. Also, the second rocker projection (452) is formed with a rear guide surface (453) on the rear surface and a second auxiliary guide surface (454) on the front surface so that it can be easily inserted into the locking hole (137), and is formed so that the sliding direction width becomes narrower toward the end.

[0140] These track rockers (410), first rocker (430), and second rocker (450) have the same rotation axis, but when the operating force is removed while they are released, they each rotate separately and are fastened to the locking hole (137). For example, the first rocker (430) and the second rocker (450) each rotate with elastic support force and are simultaneously engaged with the locking hole (137) to be fastened symmetrically in the sliding direction, or one of them may be supported first in the locking hole (137) and less fastened, while the other one is more fastened and asymmetrically fastened in the sliding direction.

[0141] Referring to FIGS. 9a to 9c, examples of the connection of the track rocker (410), the first rocker (430), and the second rocker (450) will be described.

[0142] FIG. 9a shows the first rocker (430) and the second rocker (450) engaged symmetrically in the locking hole (137). The first rocker (430) and the second rocker (450) are engaged such that the length of the first rocker projection (432) and the second rocker projection (452) engaged in the locking hole (137) is the same, that is, the end position of the first rocker projection (432) and the end position of the second rocker projection (452) are the same.

[0143] And, respectively, the front guide surface (433) of the first rocker projection (432) supports the front surface of the locking hole (137), and the rear guide surface (453) of the second rocker projection (452) supports the rear surface of the locking hole (137). In addition, the track rocker projection (416) is connected such that the distance from the front surface of the locking hole (137) is equal to the distance from the rear surface of the locking hole (137).

[0144] FIGS. 9b and 9c show the first rocker (430) and the second rocker (450) engaged asymmetrically in the locking hole (137).

[0145] When the operating force on the locking unit (400) is removed, the first rocker (430) and the second rocker (450) return to their original positions by the restoring force of the first rocker elastic member (402) and the second rocker elastic member (403), respectively. At this time, when the protrusions (416, 432, 452) are positioned on the rear side of the locking hole (137), as shown in FIG. 9b, the second rocker protrusion (452) is supported by the locking hole (137) and is less engaged, while the first rocker protrusion (432) is more engaged with the locking hole (137). Accordingly, the first rocker projection (432) has a longer length of connection to the locking hole (137) compared to the second rocker projection (452), that is, the connection amount of the first rocker projection (432) is greater, and the end position of the first rocker projection (432) is engaged so that the end position of the second rocker projection (452) protrudes further. The end of the first rocker projection (432) protrudes further outward from the lower rail (100) than the end of the second rocker projection (452).

[0146] Accordingly, while the front guide surface (433) of the first rocker projection (432) supports the front surface of the locking hole (137), the second rocker projection (452) penetrates into the locking hole (137) and the rear guide surface (453) supports the rear surface of the locking hole (137), thereby being fitted together. Thus, the movable bracket (200) can be locked without play along the sliding direction on the lower rail (100). At this time, the track rocker projection (416) is fastened such that the distance from the front surface of the locking hole (137) is narrower than the distance from the rear surface of the locking hole (137).

[0147] Conversely, when the protrusions (416, 432, 452) are positioned on the front side of the locking hole (137), as illustrated in FIG. 9c, the first rocker protrusion (432) is supported in the locking hole (137) and is less engaged, while the second rocker protrusion (452) is more engaged in the locking hole (137). Accordingly, the second rocker protrusion (452) has a longer length engaged in the locking hole (137) compared to the first rocker protrusion (432), that is, the amount of engagement of the second rocker protrusion (452) is greater, and the end position of the second rocker protrusion (452) is engaged so that the end position of the first rocker protrusion (432) protrudes more. The end of the second rocker projection (452) protrudes further outward from the lower rail (100) than the end of the first rocker projection (432).

[0148] Accordingly, while the rear guide surface (453) of the second rocker projection (452) supports the rear surface of the locking hole (137), the first rocker projection (432) penetrates into the locking hole (137) and the front guide surface (433) supports the front surface of the locking hole (137), thereby being fitted together. Thus, the movable bracket (200) can be locked without play along the sliding direction on the lower rail (100). At this time, the track rocker projection (416) is fastened such that the distance from the rear surface of the locking hole (137) is narrower than the distance from the front surface of the locking hole (137).

[0149] In addition, the track rocker (410) is provided with a rocker support (413) so that the protrusions (416, 432, 452) can be completely disengaged from the locking hole (137) when the locking unit (400) is operated.

[0150] The rocker support portion (413) is formed by protruding from two places on the track rocker body (411) and supports the surface facing the outer wall portion (130) of the first rocker body (431) and the surface facing the outer wall portion (130) of the second rocker body (451), respectively. Accordingly, when the track rocker body (411) rotates during operation of the locking unit (400) and the track rocker (410) is released from the locking hole (137), the first rocker (430) and the second rocker (450) are supported by the rocker support portion (413) and also rotate, and the first rocker projection (432) and the second rocker projection (452) are released from the locking hole.

[0152] Meanwhile, below, the detachable unit (500) will be described with reference to FIGS. 6, FIGS. 10 to 11.

[0153] The detachable unit (500) is installed on the moving bracket (200) and is restrained to the lower rail (100), and is released from the lower rail (100) when operated, and the detachable unit (500) operates in conjunction with the connecting unit (600) to be described later when the detachable lever (31) is operated. At least one detachable unit (500) is provided, and if multiple units are provided, they are connected to operate simultaneously through the shaft (630) to be described later.

[0154] In particular, the detachable unit (500) according to the present invention operates according to the operation of the detachable lever (31), and operates and maintains the operated state when the detachable lever (31) is pressed or pulled only once. That is, it operates to be released from the lower rail (100) according to the operation of the detachable lever (31) and maintains the released state. Also, when the detachable unit (500) operates to be restricted to the lower rail (100), operation of the detachable lever (31) is not required. For example, the detachable unit (500) can be pressed against the lower rail (100) to be restricted to the lower rail (100).

[0155] This detachable unit (500) is operably installed on a moving bracket (200) and is configured to include a rail catch (510) and a rotating link (530).

[0156] The rail catch (510) and the rotating link (530) maintain the connected state of the rail catch (510) by applying a supporting force to the rail catch (510) when the rail catch (510) is connected to the detachable part (121), and when the rail catch (510) is released from the detachable part (121), the rail catch (510) applies a supporting force to the rotating link (530) to maintain the rotating state of the rotating link (530) rotated at a predetermined angle.

[0157] And, the supporting force maintaining the fastening state of the rail catch (510) is removed when the detachment lever (31) is operated, and the supporting force maintaining the rotational state of the rotation link (530) can be removed when the rail catch (510) is fastened to the detachment part (121).

[0159] The rail catch (510) is rotatably installed on the movable bracket (200) and is connected to or disconnected from the detachable part (121). The rail catch (510) supports and maintains the rotational state of the rotating link (530), which will be described later, rotated at a predetermined angle.

[0160] One side of the rail catch (510) is rotatably installed on the moving bracket (200) via a pin, and is secured to the detachable part (121) by having a rail support part (511) and a rail fastening part (513) formed by protruding in one direction and spaced apart with a space into which the detachable part (121) is inserted.

[0161] The rail support member (511) is formed to protrude from the rail catch (510) toward the inner wall member (120), and when the rail catch (510) is fastened to the detachable member (121), the rail support member (511) engages with the upper surface of the detachable member (121). More precisely, the rail support member (511) may engage with the slide surface (125) of the detachable member (121), but is not limited thereto.

[0162] The rail fastening portion (513) is formed to protrude from the rail catch (510) toward the inner wall portion (120), and the detachable portion (121) is fastened between it and the rail support portion (511). When the rail catch (510) is fastened to the detachable portion (121), the end of the rail fastening portion (513) is inserted into the seating groove (123) and supported.

[0163] That is, when the rail catch (510) is attached to the detachable part (121), the rail support part (511) supports the upper side of the detachable part (121) and the rail fastening part (513) supports the lower side of the detachable part (121).

[0164] Additionally, the rail support portion (511) is formed to protrude further in one direction than the rail fastening portion (513). More specifically, when the rail catch (510) is released from the detachable portion (121), the rail support portion (511) is formed to slope downward toward the inner wall portion (120), and its end is formed to be closer to the inner wall portion (120) than the rail fastening portion (513). This rail support portion (511) is configured as an operating portion for the rail catch (510) to be fastened to the detachable portion (121).

[0165] Additionally, the rail catch (510) is further provided with a fixing projection (515) that supports the rotating link (530) to maintain the fastening state of the rail catch (510) or supports the rotating link (530) to maintain the rotational state of the rotating link (530). The fixing projection (515) is provided on one side of the rail catch (510) and is formed in a fan shape, for example, consisting of a fastening jaw (515a) and a link supporting surface (516b). The fastening jaw (515a) of this fixing projection (515) is supported by the fastening part (531a) of the stopper (531) to be described later, and the link supporting surface (516b) can support the rotational fixing part (531b) of the stopper (531) to be described later.

[0166] For example, the rail catch (510) may be formed by integrally connecting a plate-shaped rail catch body, which is composed of a pair having a rail support (511) and a fixing projection (515), through a rail fastening part (513).

[0168] Additionally, the rail catch (510) may further be provided with a catch cover (517) formed to surround the rail support member (511). When the rail catch (510) remounts the movable bracket (200) to the lower rail (100), the rail support member (511) is supported by first coming into contact with the lower rail (100), so the rail support member (511) may be subjected to impact when supported by the lower rail (100). Therefore, the rail catch (510) is provided with a catch cover (517) formed to surround at least a portion of it to absorb the impact transmitted to the rail catch (510) and prevent damage to the rail catch (510).

[0169] In particular, the catch cover (517) is formed so that the portion corresponding to the rail fastening part (513) is removed. As a portion of the catch cover (517) is removed and the rail fastening part (513) is exposed to the outside, the rail fastening part (513) can be directly contacted and supported by the seating groove (123), and the fastening force between the rail catch (510) and the detachable part (121) is increased.

[0170] Additionally, the catch cover (517) is formed so that the portion corresponding to the fixed projection (515) is removed. As a portion of the catch cover (517) is removed and the fixed projection (515) is exposed to the outside, the fixed projection (515) comes into direct contact with the stopper (531), and no movement occurs when the fixed projection (515) and the stopper (531) are supported by each other. That is, the supporting force between the rail catch (510) and the rotating link (530) is increased.

[0171] Additionally, the catch cover (517) is formed to surround the part into which the detachable part (121) of the rail catch (510) is inserted, and is provided with an upper support part (517a) that supports the upper side of the detachable part (121) and a lower support part (517b) that supports the lower side of the detachable part (121). That is, when the rail catch (510) is fastened to the detachable part (121), the detachable part (121) is fastened by fitting between the upper support part (517a) and the lower support part (517b). Accordingly, damage to the lower rail (100) can be prevented, and the movable bracket (200) is not lifted from the lower rail (100), that is, play is prevented in the restraining part between the lower rail (100) and the movable bracket (200).

[0172] Additionally, a rail catch elastic member (501) is provided that elastically deforms to elastically support the rail catch (510) when the rail catch (510) is supported on the lower rail (100) and operated to be fastened to the detachable part (121). The rail catch elastic member (501) is restored when the rail catch (510) is separated from the lower rail (100) and returns the rail catch (510) to its original position.

[0174] The rotating link (530) is rotatably installed on the moving bracket (200) to support the rail catch (510). Specifically, the rotating link (530) further supports the rail catch (510) attached to the detachable part (121) to prevent the rail catch (510) from rotating in the direction of being released from the detachable part (121). That is, even if an impact occurs, the rail catch (510) is supported by the rotating link (530) and cannot rotate in the direction of being released from the detachable part (121), and remains attached to the detachable part (121). In addition, when the rotating link (530) is operated, it rotates around a rotation axis and maintains the rotated state supported by the rail catch (510).

[0175] One side of the rotating link (530) is installed on the moving bracket (200) via a pin. This rotating link (530) is installed to be rotatable around the axis of the pin.

[0176] The rotating link (530) is provided with a stopper (531) that supports the rail catch (510) to maintain the fastening state of the rail catch (510) or is supported by the rail catch (510) to maintain the rotational state of the rotating link (530). The stopper (531) is provided on one side of the rotating link (530) and may be formed in a fan shape, for example, consisting of a fastening part (531a) and a rotational fixing part (531b). In this stopper (531), the fastening part (531a) may support the fastening jaw (515a) of the rail catch (510), and the rotational fixing part (531b) may be supported on the link support surface (516b) of the rail catch (510).

[0177] Additionally, the rotating link (530) is provided with a shaft fixing part (533) on the other side. The shaft fixing part (533) is formed by protruding a portion of the outer surface of the rotating link (530), and a shaft (630) is fixed by passing through the protruding end.

[0178] For example, the rotating link (530) may be formed by integrally connecting a pair of plate-shaped rotating link bodies, each having a shaft fixing part (533), through a stopper (531), and depending on the operation, a part of the rail support part (511) or the fixing projection (515) of the rail catch (510) may be rotated and positioned between the rotating link bodies.

[0179] Additionally, a rotational link elastic member (502) is provided that elastically deforms to elastically support the rotational link (530) when the rotational link (530) rotates according to the operation of the detachment unit (500). The rotational link elastic member (502) is restored when the rail catch (510) is fully engaged with the detachment part (121) and returns the rotational link (530) to its original position. That is, the rotational link elastic member (502) elastically deforms when the rotational link (530) rotates and the rail catch (510) is released from the detachment part (121).

[0181] Meanwhile, below, the connection unit (600) will be described with reference to FIG. 6 and FIG. 12.

[0182] The connecting unit (600) operates according to the operation of the detachment lever (31), and when operated, it simultaneously operates the detachment unit (500) and the locking unit (400). Additionally, at least one detachment unit (500) may be provided. If multiple detachment units (500) are provided, the connecting unit (600) operates the locking unit (400) and multiple detachment units (500) at once when operated. Furthermore, the connecting unit (600) maintains the operating state in which the detachment unit (500) and the locking unit (400) are operated when the detachment lever (31) is operated.

[0183] This connecting unit (600) may be positioned adjacent to the detachable operating part (31a) of the detachable lever (31) and may be configured to include a connecting link (610), a shaft (630), and a pressing piece (650).

[0184] The connecting link (610) is rotatably installed on the moving bracket (200) and rotates when the detachable lever is operated.

[0185] This connecting link (610) is provided with a detachable operating part (617) positioned adjacent to the detachable operating part (31a). The detachable operating part (617) is positioned to be pressed against the detachable operating part (31a) when the detachable lever (31) is operated. For example, the detachable operating part (617) may be formed by protruding a portion of the outer surface of the connecting link (610) in a sliding direction, and the detachable operating part (31a) is supported.

[0186] The connecting link (610) is provided with a shaft connecting part (611) to be coupled with the detachable unit (500) and a pressing part connecting part (615) to be coupled with the locking unit (400).

[0187] The shaft connecting portion (611) is provided on one side of the connecting link (610) and has a moving hole (613) through which the shaft (630) is inserted. The moving hole (613) is formed lengthwise along one direction so that the shaft (630) can be inserted and moved.

[0188] The pressing piece connecting part (615) is provided on the other side of the connecting link (610) so that the pressing piece (650) is rotatably connected.

[0189] The connecting link (610) is provided with a connecting link elastic member (not shown) that elastically deforms when the connecting link (610) is pressed by the detachable lever (31) and elastically supports the connecting link (610). The connecting link elastic member is restored when the external force applied to the connecting link (610) is removed, and returns the connecting link (610) to its original position. Specifically, when the detachable unit (500) is fastened to the detachable part (121), the external force applied to the connecting link (610) is removed, and the connecting link elastic member returns the connecting link (610) to its original position.

[0190] A shaft (630) is provided to rotate the rotating link (530) when the connecting link (610) rotates. The shaft (630) is formed long along the sliding direction and is positioned through the moving hole (613), and the shaft fixing part (533) of the rotating link (530) is fixed. For example, the shaft fixing part (533) is fixed at each end of the shaft (630).

[0191] A pressing member (650) is provided to operate the locking unit (400) when the connecting link (610) rotates. The pressing member (650) is rotatably connected to the connecting link (610) via a connecting pin (601). One side of the pressing member (650) is rotatably connected to the pressing member connecting part (615) of the connecting link (610), and the other side is provided with a pressing end (651) that presses the track rocker (410) of the locking unit (400). The pressing end (651) is positioned adjacent to the locking release operating part (412) of the track rocker (410). For example, the pressing end (651) may be positioned to contact the upper surface of the locking release operating part (412).

[0192] Additionally, the pressing piece (650) is provided with a pressing piece elastic member (602) that elastically deforms when the pressing piece (650) rotates according to the rotation of the connecting unit (600) and elastically supports the pressing piece (650), and the pressing piece elastic member (602) is restored when the connecting unit (600) returns to its original position and returns the pressing piece (650) to its original position.

[0194] Below, with reference to FIGS. 13 and 14, the operating structure of the connecting unit (600), detachable unit (500), and locking unit (400) according to the present invention will be described.

[0195] FIGS. 13a and FIGS. 14a show the basic state before operating the detachment lever (31), where the detachment unit (500) is constrained to the detachment part (121) and the locking unit (400) is fastened to the locking hole (137) so that the movable bracket (200) is fixed to the lower rail (100). At this time, referring to FIG. 13a, the rail catch (510) has the upper support part (517a) and the lower support part (517b) of the detachment part of the catch cover (517) supporting the detachment part (121), and the rail fastening part (513) is inserted into the seating groove (123). In addition, the fastening jaw (515a) of the fixing projection (515) is supported by the fastening part (531a) of the rotating link (530). According to this structure, the rail catch (510) is completely fixed in the rotational direction between the fastening part (531a) and the seating groove of the detachable part (121).

[0196] And, the rotating link (530) has a stopper (531) positioned between the rail support (511) and the fixed projection (515). The shaft (630) is positioned at one end of the moving hole (613) or adjacent to one end.

[0197] In this state, when the locking release lever (33) is operated, the connecting unit (600) and the detachable unit (500) maintain their original state as shown in FIG. 13a, and the locking unit (400) rotates clockwise in the drawing as shown in FIG. 14b and is separated from the locking hole (137).

[0198] Then, when the detachment lever (31) is operated, as shown in FIG. 13b, the connecting link (610) is pressed against the detachment action part (31a) and rotates clockwise in the drawing. At the same time, the rotating link (530) rotates counterclockwise in the drawing, and the shaft (630) moves along the moving hole (613) and is positioned at the other end of the moving hole (613) or adjacent to the other end. Accordingly, the stopper (531) of the rotating link (530) comes out between the rail support part (511) and the fixing projection (515) of the rail catch (510), and the supporting force between the fastening part (531a) and the fastening jaw (515a) disappears.

[0199] The rail catch (510) can be rotated clockwise by the restoring force of the rail catch elastic member (501) according to the rotation of the rotating link (530).

[0200] As the connecting link (610) rotates, the connecting link elastic member and the pressing member elastic member (602) undergo elastic deformation. As shown in FIG. 14b, the pressing member (650) is not rotated together with the connecting link (610) because the pressing end (651) is caught on the locking release operating part (412) of the locking unit (400), and the pressing end (651) is supported by the locking release operating part (412) and gradually operates the locking unit (400). Accordingly, the locking unit (400) is supported by the pressing member (650) and rotates clockwise in the drawing and is separated from the locking hole (137).

[0201] To explain further, when the moving bracket (200) is removed from the lower rail (100), as shown in FIG. 13c, the rail catch (510) rotates counterclockwise in the drawing due to the restoring force of the rail catch elastic member (501), and the link support surface (516b) supports the rotation fixing part (531b). Accordingly, the rotational state of the rotation link (530) is fixed, the rotational state of the connecting link (610) is fixed, and the state in which the pressing piece (650) presses the track rocker (410) is fixed.

[0202] FIG. 13d shows the movable bracket (200) lifted higher than in FIG. 13c, and the track rocker (410) is also shown.

[0203] As described, the detachable unit (500) and the locking unit (400) each maintain a state of being released from the lower rail (100) and a state of being released from the lower rail (100), and can be removed from the lower rail (100) and pass through the opening (110).

[0204] In this state, it remains fixed unless the rail catch (510) is rotated, and returns to its original state when the movable bracket (200) is mounted on the lower rail (100) again.

[0205] Specifically, when the detachable unit (500) is in a released state, if the moving bracket (200) moves toward the lower rail (100) to be mounted on the lower rail (100), the rail support portion (511) of the detachable unit (500) is first supported on the lower rail (100) as shown in FIG. 13c. As the rail support portion (511) is pressed against the detachable portion (121), the rail catch (510) can rotate and operate to be restrained on the lower rail (100) as shown in FIG. 13b. The rail catch (510) can rotate until the link support surface (516b) of the rail catch (510) is separated from the rotation fixing portion (531b) of the rotation link (530). Then, the link support surface (516b) supporting the stopper (531) disappears, and the rotating link (530) rotates by the restoring force of the rotating link elastic member (502) as shown in FIG. 13a and returns to its original state, and is inserted between the rail support part (511) and the fixing projection (515) of the rail catch (510). Then, the fastening part (531a) supports the fastening jaw (515a) to maintain the rail catch (510) in a state where it is constrained to the detachable part (121). Also, when the rotating link (530) rotates by the restoring force of the rotating link elastic member (502), the shaft (630) moves along the moving hole (613) and is positioned at one end of the moving hole (613) or adjacent to one end. At the same time, the connecting link (610) is returned to its original position by the connecting link elastic member, and the pressing piece (650) is also lifted while returning to its original position. Accordingly, the locking unit (400) is also returned to its original position and secured to the locking hole (137), and the movable bracket (200) and the lower rail (100) are completely fixed.

[0207] Meanwhile, below, a power unit (700) will be described with reference to FIGS. 15 to 17.

[0208] The movable structure (30) may be a home appliance or a vehicle seat or console having additional functions such as heating or charging, and requires power supply and signal connection. Accordingly, the sliding device (10) according to the present invention is equipped with a power unit (700) that can be electrically connected when the movable structure (30) is fixed on the lower rail (100).

[0209] The power unit (700) electrically connects the fixed part (20) and the movable structure (30), and when operated, the electrical connection between the fixed part (20) and the movable structure (30) is released, and it can operate when the locking unit (400) is operated. That is, the power unit (700) can operate when the detachment lever (31) is operated or the locking release lever (33) is operated.

[0210] This power unit (700) may be composed of a rail power unit (730) installed on a lower rail (100) and a bracket power unit (710) installed on a moving bracket (200).

[0211] The rail power supply unit (730) is installed so as to be fixed to the lower rail (100) to cover the entire wall of one side of the lower rail (100), and is configured to include a power supply panel (731) and an insulating cover (733).

[0212] In particular, the rail power supply unit (730) is positioned on the outer side of the lower rail (100) to ensure user safety and prevent short circuits caused by the ingress of foreign matter, and is positioned on the opposite side of the pair of lower rails (100) facing each other.

[0213] The power supply panel (731) is electrically connected to the power supply and control units of the fixed part (20). This power supply panel (731) is formed in a plate shape having a certain width and consists of at least one panel that is formed lengthwise along the lower rail (100). The present invention includes a first panel (731a) and a second panel (731b) that are formed lengthwise along the lower rail (100) and spaced apart from each other, so that the power supply panel (731) is connected to the moving structure (30) to supply power as well as transmit and receive signals. In addition, by providing the first panel (731a) and the second panel (731b), even if the electrical connection of either one is severed, the other one remains electrically connected, allowing for stable power supply and signal connection to the moving structure (30).

[0214] The rail power supply unit (730) is positioned facing the outer wall unit (130) at a location spaced apart from the outer wall unit (130). Additionally, a power supply panel (731) is positioned opposite the locking hole (137). The first panel (731a) and the second panel (731b) can be positioned at an angle so that they gradually move further away from the outer wall unit (130) as they go further apart. Furthermore, the first panel (731a) is electrically connected to the power supply unit of the fixed unit (20), and the second panel (731b) is electrically connected to the control unit of the fixed unit (20) to supply power and signals to the movable structure (30).

[0215] The rail power supply unit (730) includes an insulating cover (733) to prevent the user from contacting the power supply panel (731) and to protect the power supply panel (731) from the outside. This insulating cover (733) covers the outer wall unit (130) from the outside of the outer wall unit (130) in which a plurality of locking holes (137) are formed, thereby preventing foreign matter from entering the inside of the lower rail (100) from the outside through the locking holes (137).

[0216] The insulating cover (733) is formed of an insulating material and is provided with a panel fixing part (734) on which a power supply panel (731) is installed. The panel fixing part (734) may be provided in the form of a plate that is bent so as to move away from the outer wall part (130) as it goes toward the center in the vertical direction. The panel fixing part (734) is provided with a panel insertion groove (735) formed by being recessed in a shape corresponding to the first panel (731a) and the second panel (731b), respectively, on the surface facing the lower rail (100).

[0217] And, the panel fixing part (734) is provided with a rail fitting part (736) that is fitted and fixed to the fitting part (133) of the lower rail (100), and a rail insertion part (737) that is inserted and fixed to the insertion groove (136) of the lower rail (100).

[0218] The rail fitting portion (736) is formed by protruding and becoming thicker at the end of the panel fixing portion (734), and is fitted and fastened between the outer wall portion (130) and the fixing rib (132).

[0219] The rail insertion part (737) is formed in a pin shape at the end protruding from the end of the panel fixing part (734) toward the protrusion (135) and is inserted and fastened into the insertion groove (136). The rail insertion part (737) is formed with a diameter larger than the entrance of the insertion groove (136) so that it can be elastically deformed and inserted into the insertion groove (136).

[0220] This insulating cover (733) is formed of a material capable of elastic deformation, so that when the bracket power unit (710), which will be described later, comes into contact, it is elastically deformed to elastically support the bracket power unit (710). Accordingly, the electrical connection between the bracket power unit (710) and the rail power unit (730) can be stably maintained by the restoring force of the insulating cover (733).

[0222] The bracket power supply unit (710) is installed on the movable bracket (200) and passes through the locking hole (137) formed in the lower rail (100) to come into contact with the rail power supply unit (730), and may be configured to include a case (711), an operating member (714), and an electrode member (717).

[0223] Referring to FIGS. 15 and 16, it may be configured to include a case (711) that is fixedly installed on a movable bracket (200) and an operating member (714) that is rotatably installed inside the case around a rotation axis.

[0224] The case (711) is provided with a connector part (712) on one side, into which wires, wiring, harnesses, etc., are inserted to supply power to the movable structure (30) or to connect signals are supported. The wire passing through the connector part (712) passes through the interior of the case (711) and is electrically connected to an electrode member (717) positioned at the end of the operating member (714). The wire is provided with sufficient length to maintain a connected state with the electrode member (717) when the operating member (714) rotates.

[0225] The case (711) is spaced apart from each other and faces each other and is provided with a pair of protective walls (713) covering both sides of the electrode member (717) to protect the electrode member (717) from the outside.

[0226] The operating member (714) is rotatably installed in the case (711), and is provided with a release operating part (715) at one end and a connection end (716) at the other end. Either side between the release operating part (715) and the connection end (716) may be rotatably installed in the case (711).

[0227] The release operating part (715) is formed in the shape of a bar that is long along the sliding direction, and its end is positioned on the rotation path of the locking release operating part (412) when the track rocker (410) rotates. That is, the release operating part (715) is positioned to be pressed when the track rocker (410) rotates, so that the operating member (714) rotates according to the rotation of the locking unit (400).

[0228] In addition, an operating member elastic member (701) that is elastically deformed when the operating member (714) rotates is installed. The operating member elastic member (701) is elastically deformed when the operating member (714) is pressed against the track rocker (410) and rotates, thereby elastically supporting the operating member (714), and when the track rocker (410) returns, it is restored to return the operating member (714) to its original position. This operating member elastic member (701) is installed by being wound around one side of the operating member (714), and one end supports the case (711), while the other end supports the elastic member support portion (717a) of the electrode member (717).

[0229] The connecting end (716) is connected to the electrode member (717) and, when the operating member (714) rotates, retracts the electrode member (717) into the inside of the case (711), and as the operating member (714) returns to its original position, advances the electrode member (717) toward the outer wall (130).

[0230] This connecting end (716) may be provided with a locking projection (716a) that is inserted into a locking hole (719) of an electrode member (717). The locking projection (716a) is inserted movably into the locking hole (719) and moves while inserted into the locking hole (719), thereby moving the electrode member (717) according to the rotation of the operating member (714).

[0231] The electrode member (717) is connected to one end of the operating member (714) and can pass through the locking hole (137) to come into contact with the rail power supply (730). The first electrode (718a) and the second electrode (718b) are fixed to two parts formed by protruding toward the outer wall (130) of the electrode member (717). The first electrode (718a) and the second electrode (718b) can be spaced apart along the vertical direction and spaced apart along the sliding direction. The first electrode (718a) and the second electrode (718b) can each pass through the locking hole (137) and come into elastic contact with the first panel (731a) and the second panel (731b). Additionally, the first electrode (718a) and the second electrode (718b) are connected to a wire passing through the connector part (712).

[0232] These electrode members (717) are provided with a locking hole (719) to be connected to an operating member (714). The locking hole (719) is formed on both sides of the electrode member (717) and a locking projection (716a) is inserted therein so that it can move toward the outer wall (130) or move away from the outer wall (130) depending on the rotation of the operating member (714). The case (711) may also be provided with a guide projection that is positioned to penetrate the electrode member (717) between a pair of protective walls and guides the electrode member (717) in a straight direction.

[0233] And, as one side of the electrode member (717) is supported by the operating member elastic member (701), when the operating member (714) rotates, the operating member elastic member (701) presses and moves away from the outer wall (130) together with the operating member (714), and as the operating member (714) returns to its original position, the connecting end (716) presses and can elastically deform the insulating cover (733).

[0235] Referring to FIG. 17a, the operating member (714) can have a release operating part (715) supported by the locking release operating part (412) of the track rocker (410), and the electrode member (717) passes through the locking hole (137) and contacts the power supply panel (731). At this time, the insulating cover (733) is elastically deformed so that the first electrode (718a) and the first panel (731a) are elastically in contact, and the second electrode (718b) and the second panel (731b) are elastically in contact, thereby stably maintaining the contact state between them. That is, even if vibration is transmitted or there is play between the parts, the electrode member (717) is stably in contact with the power supply panel (731).

[0236] Here, when the locking unit (400) is operated, the track locker (410) rotates so that the locking release operating part (412) presses the connection release operating part (715), and the operating member (714) rotates. As the operating member (714) rotates, the electrode member (717) is pressed by the operating member elastic member (701), separated from the locking hole (137), and moves into the inside of the case (711). The moving structure (30) is configured so that power and electrical signal connections are cut off when sliding along the lower rail (100), and power and signals can be transmitted and received when the moving structure (30) is fixed in position on the lower rail (100).

[0238] Meanwhile, below, the sliding unit (300) will be described with reference to FIGS. 18 and FIGS. 19.

[0239] The sliding unit (300) is installed on the movable bracket (200) to support the forward and backward sliding movement of the movable bracket (200).

[0240] This sliding unit (300) is positioned spaced apart from the lower wall portion (140) mounted on the fixed portion (20) of the lower rail (100) and can be arranged to roll along the upper surface of the lower rail (100). This sliding unit (300) may be configured to include a rolling member (330) and an auxiliary rolling member (350), and prevents flow in the width direction during the sliding movement of the moving bracket (200).

[0241] The rolling member (330) has a rotation axis positioned outside the lower rail (100) to support one side of the lower rail (100) in the width direction. The rolling member (330) is rotatably installed on a movable bracket (200), but can be rotatably installed on a rotating shaft (310) fixed to the movable bracket (200). The rotating shaft (310) is installed by penetrating the movable bracket (200) in the width direction, and a hollow damping member (not shown) is interposed between the rotating shaft (310) and the rolling member (330) to absorb vibrations transmitted through the rolling member (330).

[0242] The rolling member (330) is formed in a hollow cylindrical shape so that its outer surface contacts the ground when the moving structure (30) is detached, and is provided so that the user can easily move the moving structure (30) even when the moving structure (30) is detached by rolling it across the ground.

[0243] When the moving structure (30) slides while constrained to the lower rail (100), the inclined surface (331) and the stepped portion (332) of the rolling member (330) each slide along the lower rail (100) to support the sliding movement of the moving bracket (200).

[0244] As such, the rolling member (330) has a rotation axis arranged along the width direction of the lower rail (100) and is equipped with an outer surface that rolls on the ground, an inclined surface (331) that rolls on the lower rail (100), and a stepped portion (332).

[0245] These rolling members (330) are positioned so that their rotation axis intersects or is offset from the rotation axis of the auxiliary rolling member (350) to be described later. Additionally, the rolling members (330) are positioned on the outer side of the lower rail (100). The rotation axis of the rolling members (330) is also positioned at a location spaced upward from the lower rail (100).

[0246] And, the axial length of the cloud member (330) is formed to be longer than the gap of the opening (110).

[0247] The rolling member (330) is provided with an inclined surface (331) on one side and a stepped portion (332) on the other side. The rolling member (330) has an inclined surface (331) formed by a recessed corner portion at one end in the axial direction, and a stepped portion (332) having a diameter smaller than the outer surface of the rolling member (330) is provided at the other end in the axial direction.

[0248] The inclined surface (331) is formed by indenting one side of the outer surface along the perimeter of the rolling member (330) to support the inner wall portion (120). The inclined surface (331) is seated on the slide surface (125) of the detachable portion (121) formed on the inner wall portion (120) and rolls along the slide surface (125). Here, the slide surface (125) and the inclined surface (331) may make point contact or line contact. Furthermore, the slide surface (125) supports the inclined surface (331) of the rolling member (330), and the outer wall portion (130) supports the auxiliary rolling member (350) to be described later, thereby supporting the sliding movement of the moving bracket (200) in both sides in the width direction. Additionally, the sliding surface (125) supports the inclined surface (331) of the rolling member (330), and the rolling surface (332a) of the stepped portion (332) supports the upper end of the outer wall portion (130), thereby supporting the sliding movement of the moving bracket (200).

[0249] The stepped portion (332) is formed such that the other side of the outer surface is stepped and recessed along the circumference of the rolling member (330) to support the outer wall portion (130). This stepped portion (332) may be composed of a connecting surface (332b) formed steppedly on the outer surface of the rolling member (330) and a rolling surface (332a) formed with a smaller diameter than the rolling member (330) to provide a cylindrical surface. That is, the stepped portion (332) is composed of a rolling surface (332a) formed with a diameter smaller than the diameter of the rolling member (330) and seated on the outer wall portion (130), and a connecting surface (332b) that connects the outer surface of the rolling member (330) and the rolling surface (332a) and is spaced apart from the outer wall portion (130). Accordingly, the rolling member (330) can reduce the contact area with the lower rail (100) during rolling motion.

[0250] In this way, the inclined surface (331) rolls on the sliding surface (125) formed on the inner wall (120), and the stepped portion (332) rolls on the upper surface of the outer wall (130).

[0252] An auxiliary rolling member (350) is rotatably installed on a movable bracket (200). Specifically, the movable bracket (200) is provided with a roller support (210) that protrudes toward the lower rail (100), passes through an opening (110), and is inserted into the inner side of the lower rail (100). An auxiliary rolling member (350) is installed on the roller support (210), which is arranged along the vertical direction and has a vertical rotation axis at its end.

[0253] The auxiliary rolling member (350) is positioned inside the lower rail (100) and supports the other side of the lower rail (100) in the width direction. That is, the inclined surface (331) of the rolling member (330) supports one side of the lower rail (100) in the width direction, and the auxiliary rolling member (350) supports the other side of the lower rail (100) in the width direction.

[0254] These auxiliary rolling members (350) support the surface facing the inner wall (120) of the outer wall (130) and roll along the surface facing the inner wall (120) of the outer wall (130).

[0255] And, the auxiliary rolling member (350) is formed with a diameter smaller than the gap of the opening (110) so that when the moving bracket (200) is removed from the lower rail (100), it passes through the opening (110) and is separated from the lower rail (100).

[0257] According to embodiments of the present invention having such a shape and structure, a sliding device can be provided in which a movable structure can be detached from a fixed part and the structure of a locking unit and a detachable unit is simple.

[0258] In addition, since the locking unit and the detachment unit remain in an unlocked state with just a single operation of the lever, the movable structure can be easily removed, and since no separate operation is required when reattaching the movable structure to the fixed part, it offers the effect of convenient use.

[0259] In addition, by providing a structure that supports each other when the detachable unit is fastened and unfastened, the fastening and supporting forces are high relative to the weight, and in particular, when the detachable unit is fastened to the lower rail, an anti-loosening structure is applied to maintain the fastened state stably, thereby improving the reliability of the product.

[0260] In addition, the locking unit is composed of three locks and features a wedge structure that is fitted into the lower rail, thereby eliminating play in the sliding direction. This provides the user with a stable user experience and improves product reliability. In particular, since no additional play prevention structure is required, it has the effect of reducing weight and cost.

[0261] In addition, as two detachable units are connected to a connecting unit via a shaft and the locking unit operates as the connecting unit, the detachable units and the locking unit are connected or unlocked in conjunction, resulting in a simple structure and a reduction in the number of parts and weight.

[0262] In addition, by providing a structure that supports the sliding of the moving structure in a direction perpendicular to the sliding direction, movement between products during sliding is minimized, and the reliability of the product is improved.

[0263] In addition, when the rolling member rolling on the ground in a detached state of the movable structure supports the lower rail when the movable structure is mounted on the fixed part and sliding, the number of parts is reduced and the weight is reduced.

[0264] In addition, it includes a power unit that electrically connects the fixed part and the movable structure, which has the effect of providing convenience to the user.

[0265] In particular, since the power unit is equipped with multiple contact points, it can stably maintain an electrical connection between the fixed part and the movable structure, and has the effect of transmitting signals as well as supplying power.

[0266] In addition, the power unit is equipped with an insulating cover to ensure user safety and protect the panel and electrodes from the outside, and has the effect of preventing foreign substances from entering the interior of the lower rail through the locking hole.

[0267] In addition, as the insulating cover undergoes elastic deformation, it can maintain contact between the electrode and the panel, effectively enabling the stable supply of power and signals to the moving structure.

[0268] Although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. Various modifications are possible by those skilled in the art without departing from the essence of the invention as claimed in the patent claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
