Description

[Technical Field]

[0001] The present invention relates to a slide lock device and a method for assembling a slide device. [Background technology]

[0002] A slide device that supports an automobile seat so that it can slide along the floor is known. Patent Document 1 discloses a slide lock device that includes a rail, a slider slidably supported on the rail, and a lock device that fixes the position of the slider relative to the rail. The slide lock device includes a casing coupled to the slider, a pair of locking members supported on the casing so as to be displaceable between an unlocked position and a locked position, a biasing member that biases the locking members to the locked position, and an operating member displaceably supported on the casing and abutting against the locking members. The operating member is driven by a lever operated by a user to move the locking members from the locked position to the unlocked position.

[0003] The rail of Patent Document 1 has a plurality of slots arranged side by side in the longitudinal direction. When the locking portion is in the locked position, it enters the slots, thereby fixing the position of the slider relative to the rail. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2021 / 125343 Summary of the Invention [Problem to be solved by the invention]

[0005] Due to variations in the size of the locking member and slot during manufacturing, a gap may occur between the wall surface of the slot and the locking member even when the locking member is in the locked position, causing the slider to wobble. Therefore, there is a need for the development of a slide locking device that can more reliably restrict longitudinal movement of the slider when the locking member is in the locked position, regardless of variations during manufacturing.

[0006] In view of the above background, an object of the present invention is to provide a slide locking device that can restrict longitudinal movement of a slider relative to a rail when a locking member is in a locked position, and a method for assembling a slide device that includes the slide locking device.

DETAILED DESCRIPTION OF THE INVENTION

[0048] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A slide device has a rail and a slider that is slidable relative to the rail. The rail is coupled to a first structure, and the slider is coupled to a second structure. The slide device moves the second structure relative to the first structure as the slider moves relative to the rail. The slide device is provided, for example, between a floor and a seat of a vehicle and moves the seat relative to the floor. In addition, an electric slide rail is provided between a base and a work holder and moves the work holder relative to the base.

[0049] (First embodiment) As shown in Fig. 1, the slide device 1 is provided between a floor 2 of a vehicle and a vehicle seat 3. The vehicle seat 3 has a seat cushion 5 that supports the buttocks of an occupant, and a seat back 6 that extends upward from the rear of the seat cushion 5 and supports the back of the occupant. The slide device 1 is provided between the floor 2 and the seat cushion 5, and supports the seat cushion 5 so that it can slide relative to the floor 2. A cover 7 is provided on the side of the seat cushion 5 to hide the gap between the seat cushion 5 and the floor 2.

[0050] As shown in FIG. 2 , the slide device 1 has left and right rails 11 extending in the front-rear direction, and left and right sliders 12 slidably supported on the rails 11. The extending direction of the rails 11 is defined as the front-rear direction. The extending direction of the rails 11 may or may not coincide with the front-rear direction of the vehicle. In other words, the extending direction of the rails 11 does not limit the mounting direction on the vehicle. In this embodiment, the extending direction of the rails 11 coincides with the front-rear direction of the vehicle. In this embodiment, the slider 12 is provided above the rails 11. Therefore, the rails 11 may be referred to as lower rails, and the sliders 12 may be referred to as upper rails.

[0051] In the following description, the rail 11 is provided so as to extend along the longitudinal direction of the vehicle. In addition, the following description defines the front, rear, up, down, left, and right directions based on the direction of the vehicle, but these directions are used for convenience of explanation, and the present invention is not limited to these directions.

[0052] 3 and 4, the rail 11 has a groove-shaped cross section. In detail, the rail 11 has a rail bottom wall 11A with faces facing up and down, left and right rail outer walls 11B extending upward from left and right edges of the rail bottom wall 11A with faces facing left and right, left and right rail upper walls 11C extending toward each other from the upper ends of the left and right rail outer walls 11B with faces facing up and down, and left and right rail inner walls 11D extending downward from the inner ends of the left and right rail upper walls 11C with faces facing left and right.

[0053] The rail bottom wall 11A, the left and right rail outer walls 11B, the left and right rail upper walls 11C, and the left and right rail inner walls 11D each extend in the front-to-rear direction. The left and right rail outer walls 11B and the left and right rail inner walls 11D extend parallel to each other and perpendicular to the rail bottom wall 11A. The lower ends of the left and right rail inner walls 11D are spaced apart from the rail bottom wall 11A. The rail 11 has a rail opening 11E at its upper portion extending in the front-to-rear direction. The rail opening 11E is defined by the left and right rail inner walls 11D. The rail 11 may be formed by press-forming a metal plate. The left and right edge portions of the rail bottom wall 11A may have upwardly protruding steps 11F. The left and right step portions 11F extend in the front-to-rear direction and have flat upper surfaces.

[0054] Each of the left and right rail inner walls 11D is formed with a protrusion 11G that protrudes toward each other and extends in the front-to-rear direction. The cross section of the left and right protrusions 11G may be formed in an arc or trapezoid shape. Each protrusion 11G may be located in the middle of the corresponding rail inner wall 11D in the up-down direction. The upper and lower ends of the left and right rail inner walls 11D are located outward from the protrusions 11G to the left and right.

[0055] As shown in Figures 2 to 4, the rail 11 has a plurality of locking holes 15 arranged in the extending direction of the rail 11, i.e., in the front-to-rear direction. The plurality of locking holes 15 are formed in the protrusions 11G of the corresponding rail inner side walls 11D. The locking holes 15 extend parallel to one another. The locking holes 15 extend vertically. It is preferable that the locking holes 15 are inclined forward or backward.

[0056] In this embodiment, the wall surfaces defining the front and rear edges of each locking hole 15 are parallel to each other.

[0057] Left and right rail grooves 17 are formed in the floor 2 and are recessed downward. The rails 11 are preferably disposed in the corresponding rail grooves 17.

[0058] 3, the slider 12 is disposed at the opening edge of the rail opening 11E and has a plate-shaped slider upper wall 12A with its faces facing up and down, left and right slider inner walls 12B extending downward from the left and right side edges of the slider upper wall 12A toward the rail bottom wall 11A, left and right slider lower walls 12C extending outward to the left and right from the lower ends of the left and right slider inner walls 12B, respectively, and left and right slider outer walls 12D extending upward from the left and right outer ends of the left and right slider lower walls 12C. The slider upper wall 12A, the left and right slider inner walls 12B, the left and right slider lower walls 12C, and the left and right slider outer walls 12D extend in the front-to-rear direction.

[0059] The slider 12 may be formed by fastening together a plurality of press-formed or roll-formed metal plates. In another embodiment, the slider 12 may be formed from a single press-formed or roll-formed metal plate. The front-to-rear length of the slider 12 is set shorter than the front-to-rear length of the rail 11. The slider 12 is connected to the seat cushion 5 at the slider upper wall 12A.

[0060] The slider upper wall 12A may be positioned higher than the left and right rail upper walls 11C or lower than the left and right rail upper walls 11C. The left and right slider inner walls 12B face left and right and face each other at a distance. The left and right slider inner walls 12B are positioned between the left and right rail inner walls 11D. Each slider inner wall 12B faces the corresponding rail inner wall 11D on the left and right with a gap between them. Each slider lower wall 12C extends left and right, passing between the rail bottom wall 11A and the lower end of the corresponding rail inner wall 11D on the left and right. The outer wall of each slider 12 is positioned between the corresponding rail outer wall 11B and rail inner wall 11D on the left and right. A plurality of wheels 18 are rotatably supported on the outer surface of each slider outer wall 12D in the left and right direction. Each wheel 18 has a rotation axis that rotates in the left and right direction and is in contact with the rail bottom wall 11A. In this embodiment, each wheel 18 is in contact with the upper surface of the step 11F of the rail bottom wall 11A. The slider 12 is able to smoothly slide along the rail 11 by contacting the rail 11 via the wheels 18. With the above configuration, the slider 12 is received in the rail 11 and slidably engages with the rail 11. In other embodiments, the slider 12 may be supported on the rail 11 via a ball or roller bearing.

[0061] The left and right slider inner walls 12B are formed with recesses 12E that are recessed toward each other and extend in the front-to-rear direction. A protrusion is formed on the rear side of the recesses 12E of the slider inner walls 12B. The cross section of the left and right recesses 12E as viewed from the front-to-rear direction may be formed in an arc shape or a trapezoid shape. Each recess 12E may be located in the middle of the corresponding slider inner wall 12B in the up-down direction. Each recess 12E is located in a position facing the protrusion 11G of the corresponding rail 11 on the left and right.

[0062] The slider 12 is formed into a groove shape that opens toward the rail bottom wall 11A, i.e., downward, by a slider upper wall 12A and left and right slider inner walls 12B. As shown in Figures 5 and 6, a slide locking device 30 is supported on the underside of the slider upper wall 12A.

[0063] 5 to 10, the slide locking device 30 includes a casing 31 coupled to the slider 12, at least one locking member 32 rotatably supported on the casing 31 between an unlocked position and a locked position, a biasing member 33 that biases the locking member 32 to the locked position, and an operating member 34 displaceably supported on the casing 31 and in contact with the locking member 32. In this embodiment, a pair of locking members 32 and biasing members 33 are provided on the left and right.

[0064] The casing 31 may be formed by combining multiple casing members 31A, 31B. In this embodiment, the casing 31 includes a lower casing member 31A and an upper casing member 31B that are coupled to each other. The left and right locking members 32 are rotatably supported between the lower casing member 31A and the upper casing member 31B. The casing 31 is coupled to the bottom surface of the slider upper wall 12A and disposed between the pair of slider inner walls 12B. This allows the slide locking device 30 to be disposed in the slider 12 with efficient space utilization. A slider opening 12F is formed in the portion of the pair of slider inner walls 12B that faces the casing 31.

[0065] The pair of locking members 32 are arranged parallel to each other. Each locking member 32 has a shaft 32A extending in the front-rear direction. That is, the rotation axis of each locking member 32 extends in the front-rear direction. The front and rear ends of the shaft 32A are rotatably supported by the casing 31. Each locking member 32 has at least one protrusion 32B protruding radially from the shaft 32A. In this embodiment, multiple protrusions 32B protrude radially from the shaft 32A to one side.

[0066] 6 and 7, the plurality of protrusions 32B may extend in a spiral shape centered on the rotation axis of the locking member 32. The plurality of protrusions 32B may be formed intermittently. The plurality of protrusions 32B may be arranged at intervals in the front-rear direction. The casing 31 may have a spiral groove 31C that slidably receives the plurality of protrusions 32B.

[0067] 6 and 8, each locking member 32 has an arm portion 32C that protrudes from the shaft portion 32A in a direction perpendicular to the rotation axis of the locking member 32. When viewed from the front-to-rear direction, the arm portion 32C extends from the shaft portion 32A in a direction opposite to the protrusion portion 32B.

[0068] Casing openings 31D are formed on the left and right sides of the casing 31. The locking member 32 rotates between a locked position in which the multiple protrusions 32B pass through the casing openings 31D and protrude outward from the casing 31, and an unlocked position in which the multiple protrusions 32B are positioned within the casing 31. When the locking member 32 is in the unlocked position, the multiple protrusions 32B are positioned above the shaft 32A. When each of the locking members 32 is in the locked position, the pair of arm portions 32C extend toward each other, i.e., laterally from the shaft 32A toward the center of the casing 31. The locked position of the locking member 32 is preferably determined by at least one of the multiple protrusions 32B abutting against the casing 31.

[0069] 6, the right locking member 32 is displaced from the unlocked position to the locked position by rotating clockwise (to the right) when viewed from the front (from the front). The left locking member 32 is displaced from the unlocked position to the locked position by rotating counterclockwise (to the left) when viewed from the front (from the front).

[0070] One of the plurality of protrusions 32B (hereinafter referred to as reference protrusion 32D) is provided with a wedge portion 32E. Each wedge portion 32E is tapered. Each wedge portion 32E is configured so that its front-to-rear width increases along the rotation direction of the locking member 32 from the locked position to the unlocked position.

[0071] Specifically, one wedge portion 32E is provided on each of the left and right locking members 32. The wedge portions 32E provided on the left and right locking members 32 are each configured so that their front-to-rear width increases along the direction of rotation of the locking member 32 from the locked position to the unlocked position.

[0072] 5 and 6, the front and rear surfaces of the wedge portion 32E of the right locking member 32 move away from each other in the rotation direction (clockwise in front view) from the locked position to the unlocked position, and the wedge portion 32E of the right locking member 32 is tapered (wedge-shaped) in side view. The front and rear surfaces of the wedge portion 32E of the right locking member 32 are inclined in the rotation direction from the locked position to the unlocked position so as to approach the wall surfaces that define the front and rear edges of the opposing locking hole 15, respectively.

[0073] The front and rear surfaces of the wedge portion 32E of the left locking member 32 are tapered (wedge-shaped) in side view, with the front and rear surfaces moving away from each other in the rotation direction from the locked position to the unlocked position. The front and rear surfaces of the wedge portion 32E of the left locking member 32 are inclined in the rotation direction from the locked position to the unlocked position (counterclockwise in front view) so as to approach the wall surfaces that define the front and rear edges of the opposing locking holes 15.

[0074] Each of the biasing members 33 is provided between the casing 31 and the corresponding locking member 32, and biases the locking member 32 toward the locked position. The biasing members 33 may be, for example, torsion coil springs. The biasing members 33 may be supported by the shaft portions 32A of the locking members 32.

[0075] The operating member 34 has a fan-shaped main body 34A with its surfaces facing left and right, and a pressing portion 34B provided at the lower end of the main body 34A. The operating member 34 is disposed in the center of the casing 31 in the left-right direction. A support shaft 34C protruding in the left-right direction is provided at the rear end of the main body 34A. The support shaft 34C is disposed at the center of the fan-shaped main body 34A when viewed left and right. The support shaft 34C is rotatably supported on the casing 31, so that the operating member 34 is supported on the casing 31 so as to be rotatable about an axis extending left and right. The upper end of the main body 34A passes through an insertion hole 35 formed in the upper casing member 31B and protrudes above the casing 31. An operating hole 36 penetrating vertically is formed in the slider upper wall 12A of the slider 12. The upper end of the main body 34A of the operating member 34 passes through the operating hole 36 and protrudes above the slider 12. The pressing portion 34B is disposed inside the casing 31. The left-right width of the pressing portion 34B is formed to be larger than the left-right width of the operating portion. When the locking member 32 is in the locked position, the operating member 34 is in the initial position. At this time, the pressing portion 34B is disposed above the left and right arm portions 32C and abuts against the arm portions 32C. The operating member 34 may be biased to the initial position by a biasing member 37.

[0076] An operating lever 41 is rotatably provided on each of the left and right sliders 12. The operating lever 41 has a lever center 41A extending in the left-right direction below the front of the seat cushion 5, and left and right lever side portions 41B extending rearward from the left and right ends of the lever center 41A. The intermediate portions of the left and right lever side portions 41B in the front-rear direction are supported on the corresponding slider 12 so as to be rotatable about a rotation shaft 41C extending in the left-right direction. The rear ends of the left and right lever side portions 41B abut from above against the upper end of the operating portion. The rear ends of the left and right lever side portions 41B are preferably biased upward by a biasing member 33 (not shown).

[0077] 9, when the operating member 34 is in the initial position, the left and right locking members 32 are in the locked position. When the left and right locking members 32 are in the locked position, the multiple protrusions 32B pass through the casing opening 31D and the slider opening 12F and protrude into the corresponding locking holes 15 of the rail 11 and are locked in the locking holes 15. This restricts the movement of the slider 12 relative to the rail 11.

[0078] Wedge portion 32E is configured so that its front-to-rear width increases along the rotation direction of locking member 32 from the locked position to the unlocked position. Wedge portion 32E is inclined in the rotation direction of locking member 32 from the locked position to the unlocked position so that its front surface approaches the front wall surface of locking hole 15 into which reference protrusion 32D protrudes, and its rear surface approaches the rear wall surface of locking hole 15 into which reference protrusion 32D protrudes.

[0079] When the left and right locking members 32 are in the locked position, the front surface of each wedge portion 32E abuts against the front wall surface that defines the locking hole 15, and the rear surface of each wedge portion 32E abuts against the rear wall surface that defines the locking hole 15. This prevents gaps from being formed between the wedge portions 32E and the front and rear wall surfaces that define the corresponding locking holes 15. Therefore, when the locking members 32 are in the locked position, movement of the slider 12 in the front-to-rear direction relative to the rail 11 is restricted, preventing rattling of the slider 12.

[0080] In order to more reliably prevent rattling of the slider 12, it is preferable that when the left and right locking members 32 are in the locked position, the front surface of the wedge portion 32E be in pressure contact with the front wall surface that defines the locking hole 15, and the rear surface of the wedge portion 32E be in pressure contact with the rear wall surface that defines the locking hole 15. It is also possible to provide the wedge portion 32E on only one of the left and right locking members 32.

[0081] In addition, although both the front and rear surfaces of the wedge portion 32E are configured to be inclined so as to approach the front and rear wall surfaces of the corresponding locking hole 15 along the rotation direction from the locked position to the unlocked position, the wedge portion 32E may be configured so that its front-to-rear width increases along the rotation direction from the locked position to the unlocked position. For example, either the front or rear surface of the wedge portion 32E may be configured to be inclined so as to approach the opposing wall surface of the locking hole 15 along the rotation direction from the locked position to the unlocked position.

[0082] When the user pulls the lever center portion 41A of the operating lever 41 upward, the rear ends of the left and right lever side portions 41B push the upper end of the main body portion 34A downward. As a result, as shown in FIG. 10 , the operating member 34 rotates and moves downward, moving from the initial position to the post-operation position. At this time, the pressing portion 34B of the operating member 34 presses the locking member 32, moving the locking member 32 from the locked position to the unlocked position. Specifically, the pressing portion 34B of the operating member 34 pushes the left and right arm portions 32C downward, causing the left and right locking members 32 to rotate from the locked position to the unlocked position. This causes the multiple protrusions 32B to disengage from the locking holes 15 of the rail 11 and move into the casing 31. This allows the slider 12 to move relative to the rail 11.

[0083] The operating member 34 presses the arm portion 32C in a first direction parallel to a tangential direction centered on the rotation axis of the locking member 32, and when the locking member 32 reaches the release position, the arm portion 32C and the operating member 34 do not overlap in the first direction. In this embodiment, the first direction is the vertical direction. According to this aspect, even if an excessive load is applied to the operating member 34, the load is not transmitted to the arm portion 32C. Therefore, damage to the locking member 32 is prevented.

[0084] When the locking member 32 moves from the locked position to the unlocked position, at least one of the protrusions 32B slides along the spiral groove 31C, allowing the locking member 32 to rotate smoothly from the locked position to the unlocked position.

[0085] In the slide lock device 30, the lock member 32 is rotatably supported by the casing 31, so that when the lock member 32 is pressed by the operating member 34, the lock member 32 can move smoothly from the locked position to the unlocked position. This makes it possible to provide a slide lock device 30 that can operate smoothly.

[0086] When the locking member 32 is in the locked position, the plurality of protrusions 32B protrude from the casing 31, and when the locking member 32 is in the unlocked position, the plurality of protrusions 32B are located inside the casing 31, thereby making it possible to reduce the gap between the casing 31 and the rail 11.

[0087] The pair of locking members 32 are arranged parallel to each other, and the operating member 34 abuts against each of the pair of arm portions 32C, so that the locking members 32 can engage with the rail 11 with good stability.

[0088] The method for assembling the slide device 1 described above includes the steps of assembling the slide lock device 30 by attaching the lock member 32, the biasing member 33, and the operating member 34 to the casing 31, attaching the casing 31 to the slider 12, and attaching the slider 12 to the rail 11. According to this embodiment, the slide lock device 30 can be assembled efficiently inside the slider 12. The steps for assembling the slide lock device 30 also include the steps of attaching the biasing member 33 to the lock member 32, supporting the lock member 32 with the biasing member 33 attached and the operating member 34 on one of the multiple casing 31 members, and connecting the multiple casing 31 members to each other. The multiple casing 31 members include a lower casing member 31A and an upper casing member 31B.

[0089] (Second embodiment) The slide lock device 30 according to the second embodiment differs from the first embodiment in that, instead of the wedge portion 32E, a cam mechanism 50 and a connecting mechanism 52 are provided between the casing 31 (also referred to as a housing) and the locking member 32. The other configurations are generally the same as those of the first embodiment, and therefore, description of the other configurations will be omitted.

[0090] As shown in FIG. 11 , the slide lock device 30 according to the second embodiment includes a pair of left and right locking members 32, similar to the first embodiment. As in the first embodiment, each locking member 32 is supported rotatably about a rotation axis extending forward and backward, and is configured to be displaceable between an unlocked position and a locked position. As in the first embodiment, the right locking member 32 (also referred to as the first locking member 32F) is displaced to the locked position by rotating clockwise (right-handed) from the unlocked position, as viewed from the front. The left locking member 32 (also referred to as the second locking member 32G) is displaced to the locked position by rotating counterclockwise (left-handed) from the unlocked position, as viewed from the front.

[0091] As in the first embodiment, the left and right locking members 32 each have a protrusion 32B. The protrusion 32B engages by projecting into the locking hole 15 when the locking member 32 is in the locked position, and disengages from the locking hole 15 when the locking member 32 is in the unlocked position. In this embodiment, as in the first embodiment, the left and right locking members 32 are provided with a plurality of protrusions 32B lined up in the front-to-rear direction. As in the first embodiment, each of the protrusions 32B extends spirally about the rotation axis of the locking member 32.

[0092] 11, similar to the first embodiment, the casing 31 may be provided with an operating member 34 that engages with the left and right locking members 32 and displaces each of them from the release position to the lock position. In addition, biasing members 33, 37 that bias the left and right locking members 32 to the lock position may be provided between the casing 31 and the casing 31, respectively.

[0093] The cam mechanism 50 guides the left and right locking members 32 to move toward each other when they move from the unlocked position to the locked position. The cam mechanism 50 is provided between the right locking member 32 and the rail 11, and between the left locking member 32 and the rail 11.

[0094] Hereinafter, the cam mechanism 50 provided between the right-side locking member 32 and the rail 11 will be referred to as the first cam mechanism 50A, and the cam mechanism 50 provided between the left-side locking member 32 and the rail 11 will be referred to as the second cam mechanism 50B.

[0095] The first cam mechanism 50A is provided between one of the protrusions 32B (hereinafter referred to as the first reference protrusion 54) provided on the right-side locking member 32 and the locking hole 15 (hereinafter referred to as the first locking hole 56) into which the first reference protrusion 54 protrudes.

[0096] The first cam mechanism 50A includes a first inclined surface 54A provided on the front surface of the first reference protrusion 54. The first inclined surface 54A is inclined forward in the counterclockwise direction, i.e., in the rotation direction of the right locking member 32 from the locked position to the unlocked position. As a result, the first inclined surface 54A is inclined so as to approach the front wall surface that defines the front edge of the first locking hole 56 in the rotation direction from the locked position to the unlocked position. When the right locking member 32 rotates with the first inclined surface 54A in contact with the front wall surface that defines the front edge of the first locking hole 56, the right locking member 32 is guided to move rearward.

[0097] The second cam mechanism 50B is provided between one of the protrusions 32B (hereinafter referred to as the second reference protrusion 58) provided on the left locking member 32 and the locking hole 15 (hereinafter referred to as the second locking hole 60) into which the second reference protrusion 58 protrudes.

[0098] The second cam mechanism 50B includes a second inclined surface 58A provided on the rear surface of the second reference protrusion 58. The second inclined surface 58A is inclined rearward in the clockwise direction, i.e., in the rotation direction of the left locking member 32 from the locked position to the unlocked position. As a result, the second inclined surface 58A is inclined so as to approach the rear wall surface that defines the rear edge of the locking hole 15 in the rotation direction from the locked position to the unlocked position. When the left locking member 32 rotates with the second inclined surface 58A in contact with the rear wall surface that defines the rear edge of the second locking hole 60, the left locking member 32 is guided to move forward.

[0099] In this way, the first cam mechanism 50A guides the right locking member 32 to move rearward, and the second cam mechanism 50B guides the left locking member 32 to move forward. Therefore, the first cam mechanism 50A and the second cam mechanism 50B guide the left and right locking members 32 to move in directions that bring them closer to each other.

[0100] The coupling mechanism 52 couples (also referred to as connecting) the left and right locking members 32 in the front-rear direction. In this embodiment, the coupling mechanism 52 includes a first coupling mechanism 52A provided between the casing 31 and the right locking member 32, and a second coupling mechanism 52B provided between the casing 31 and the left locking member 32, and the left and right locking members 32 are coupled via the casing 31.

[0101] The first coupling mechanism 52A includes a first recess 62 provided in the casing 31 and a protrusion 32B (hereinafter referred to as a first engaging protrusion 64) provided in the right locking member 32 and received in the first recess 62. In this embodiment, the first recess 62 is provided in a left portion of the right locking member 32 of the casing 31, and the first engaging protrusion 64 is located at the frontmost of the protrusions 32B provided on the right locking member 32. The first engaging protrusion 64 preferably extends from the right side surface to the left side surface of the right locking member 32 when the right locking member 32 is in the locked position so as to be receivable in the first recess 62.

[0102] The second coupling mechanism 52B includes a second recess 66 provided in the casing 31 and a protrusion 32B (hereinafter referred to as a second engaging protrusion 68) provided in the left locking member 32 and received in the second recess 66. In this embodiment, the second recess 66 is provided in a right portion of the left locking member 32 of the casing 31, and the second engaging protrusion 68 is located at the rearmost of the protrusions 32B provided on the left locking member 32. The second engaging protrusion 68 preferably extends from the left side surface to the right side surface of the left locking member 32 when the left locking member 32 is in the locked position so as to be receivable in the second recess 66.

[0103] When the right locking member 32 moves rearward, the first engagement protrusion 64 abuts against the rear wall surface of the first recess 62, and the casing 31 is pushed rearward. This causes the left locking member 32 to be pushed rearward. When the left locking member 32 moves forward, the second engagement protrusion 68 abuts against the front wall surface of the second recess 66, and the casing 31 is pushed forward. This causes the right locking member 32 to be pushed forward.

[0104] Next, the operation and effects of the slide lock device 30 configured as above will be described.

[0105] When the right locking member 32 rotates from the unlocked position toward the locked position and the first inclined surface 54A abuts against the front wall surface of the first locking hole 56, the right locking member 32 moves rearward, guided by the first inclined surface 54A and the front wall surface. The rearward movement of the right locking member 32 pushes the casing 31 out and moves rearward. The rearward movement of the casing 31 also pushes the left locking member 32 rearward. As a result, the second inclined surface 58A of the second reference protrusion 58 provided on the left locking member 32 abuts against the rear wall surface of the second locking hole 60.

[0106] When the left locking member 32 rotates from the unlocked position toward the locked position and the second inclined surface 58A abuts against the rear wall surface of the second locking hole 60, the left locking member 32 moves forward, guided by the second inclined surface 58A and the rear wall surface. The forward movement of the left locking member 32 pushes the casing 31 forward. The forward movement of the casing 31 also pushes the right locking member 32 forward. As a result, the first inclined surface 54A of the first reference protrusion 54 provided on the right locking member 32 abuts against the front wall surface of the first locking hole 56.

[0107] By the time the left and right locking members 32 reach their respective locked positions, the first inclined surface 54A of the first reference protrusion 54 abuts against the front wall surface of the first locking hole 56, and the second inclined surface 58A of the second reference protrusion 58 abuts against the rear wall surface of the second locking hole 60.

[0108] Before the left and right locking members 32 reach their respective locked positions, the first inclined surface 54A of the first reference protrusion 54 abuts against the front wall surface of the first locking hole 56, and the second inclined surface 58A of the second reference protrusion 58 abuts against the rear wall surface of the second locking hole 60. Therefore, when the left and right locking members 32 are in their respective locked positions, no gap is created between the locking members 32 and the wall surface that defines the locking hole 15, preventing rattling of the locking members 32 relative to the rail 11 when in the locked position. This makes it possible to provide a slide locking device 30 that can reliably restrict movement of the slider 12 relative to the rail 11 in the longitudinal direction of the rail 11.

[0109] Furthermore, when the first inclined surface 54A and the second inclined surface 58A come into contact with the wall surfaces that define the corresponding locking holes 15, the right locking member 32 pushes the casing 31 rearward, and the left locking member 32 pushes the casing 31 forward. As a result, as shown by the arrows in Fig. 11, the right locking member 32 and the left locking member 32 each push the casing 31 in opposite directions (more specifically, in opposing directions).

[0110] When the left and right locking members 32 are in their respective locked positions, it is preferable that the right locking member 32 is pushed forward by the left locking member 32, with the first inclined surface 54A in pressure contact with the front wall surface of the first locking hole 56. Similarly, it is preferable that the left locking member 32 is pushed rearward by the right locking member 32, with the second inclined surface 58A in pressure contact with the rear wall surface of the second locking hole 60.

[0111] The method of assembling the slide device 1 according to the second embodiment may be the same as that of the first embodiment. Specifically, the method of assembling the slide device 1 includes the steps of attaching the left and right locking members 32, the biasing member 33, and the operating member 34 to the casing 31 to assemble the slide locking device 30, attaching the casing 31 to the slider 12, and attaching the slider 12 to the rail 11. According to this aspect, it is possible to provide the slide device 1 including the slide locking device 30 that is prevented from rattling, and to assemble the slide locking device 30 inside the slider 12 with good work efficiency.

[0112] Although the description of the specific embodiment has been completed above, the present invention is not limited to the above embodiment and can be widely modified and implemented.

[0113] In the second embodiment, the cam mechanism 50 is configured to push out the left and right locking members 32 in opposite directions, but the present invention is not limited to this.

[0114] Fig. 12 shows a modified example of the slide locking device 30 according to the second embodiment. As shown in Fig. 12, the cam mechanisms 50 may be provided between the protrusions 32B and the corresponding locking holes 15, respectively, and configured to guide the left and right locking members 32 in directions away from each other. In this case, too, the left and right locking members 32 may be linked (connected) in the front-rear direction by the linking mechanism 52, as in the second embodiment.

[0115] 12, the right locking member 32 is guided by the cam mechanism 50 (first cam mechanism 50A) and pushed forward. As a result, similar to the second embodiment, the casing 31 is pushed forward by the right locking member 32, and the second inclined surface 58A of the left locking member 32 abuts against the front wall surface of the second locking hole 60.

[0116] The left locking member 32 is guided by the cam mechanism 50 (second cam mechanism 50B) and pushed rearward. As a result, similar to the second embodiment, the casing 31 is pushed rearward by the left locking member 32, and the first inclined surface 54A of the right locking member 32 abuts against the rear wall surface of the first locking hole 56. As a result, as shown by the arrows in FIG. 12 , the right locking member 32 and the left locking member 32 each push the casing 31 in opposite directions (more specifically, in directions away from each other), and they are in a state of pulling against each other. As with the second embodiment, when the left and right locking members 32 are in their respective locked positions, no gaps are created between the locking members 32 and the wall surfaces that define the front and rear edges of the locking hole 15, preventing rattling of the locking members 32 against the rail 11 when in the locked position.

[0117] In the second embodiment, the first inclined surface 54A is provided on the front surface of the first reference protrusion 54, but in addition to the first inclined surface 54A, an inclined surface that is inclined so as to approach the rear wall surface of the locking hole 15 may also be provided on the rear surface of the first reference protrusion 54, and a wedge portion 32E similar to that in the first embodiment may be formed on the first reference protrusion 54. Similarly, the second inclined surface 58A is provided on the rear surface of the second reference protrusion 58, but in addition to the second inclined surface 58A, an inclined surface that is inclined so as to approach the front wall surface of the locking hole 15 may also be provided on the front surface of the second reference protrusion 58, and a wedge portion 32E similar to that in the first embodiment may also be formed on the second reference protrusion 58.
