Description

Technical Field

[0001] The present invention relates to a detachable slide rail that can be easily attached and detached, in which a drawer, equipment, etc. once stops in the state where it is most pulled out from the main body, and the drawer, equipment, etc. (moving side rail) can be pulled out from the main body (fixed side rail) by a simple operation as needed.

Background Art

[0002] Conventionally, a detachable slide rail including a fixed side rail connected to a fixed side member, a moving side rail supported so as to be pullable with respect to the fixed side rail via a ball retainer, and a release lever for making the moving side rail detachable from the fixed side rail. Even in a state where the moving side member is maximally pulled out from the fixed side member, the fixed side rail is set to a length that is concealed by the moving side member, and when the moving side rail is pulled out from the fixed side rail together with the moving side member, a slide rail that remains on the fixed member side together with the fixed side rail at the tip side of the fixed side rail is provided by the applicant of the present application. (See Patent Document 1)

[0003] In Patent Document 1, as an example of a release lever for preventing detachment, a structure including a mounting substrate 51, an elastic transition portion 52, and a transition stopper portion 6 provided with an operation portion 61 and a stopper 63 is described in paragraph 0030 as an example. And, as described in paragraph 0040 of Patent Document 1, the moving side rail 2 is pulled out from the fixed side rail 1 by pushing the operation portion 61 inward in the pulling direction.

[0004] And, since the elastic transition portion 52 actively promotes elastic deformation, it is difficult to ensure rigidity. As described in paragraph 0039, the stopper protruding portion 313 of the ball retainer 3 abuts on the stopper 63 of the release lever for preventing detachment, so that the function of preventing the moving side rail from coming off acts, but there is a problem that the elastic transition portion 52 is easily damaged when an impact is applied to the stopper 63. In particular, if the rigidity of the elastic shift section 52 is too high, the operation of the control section becomes heavy, and if the rigidity is reduced, it breaks, making it difficult to set the rigidity of the elastic shift section 52. Furthermore, since the operating mechanism is usually hidden by a moving component, the operator may not only push the operating mechanism inward in the pulling direction, but also accidentally push it outward in the opposite direction, the retracting direction. If an operator pushes the rail 2 outward in the retraction direction and mistakenly believes that the rail 2 is detached, and pulls the rail 2, the stopper projection 313 and the stopper 63 will be in contact, causing excessive stress on the elastic shifting section 52, which can lead to damage. Thus, in the embodiment described in Patent Document 1, while no problems occur during normal use, there is a problem that it is prone to damage during use outside of normal use. Furthermore, while such slide rails are usually used in pairs, if the operating section 61 is located only on one side of the fixed rail 1, as in the embodiment of Patent Document 1, it was necessary to prepare two types of slide rails, one for the right and one for the left.

[0005] [Patent Document 1] Patent No. 6689695 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] In view of the above problems, the present invention aims to provide a removable slide rail with a simple structure that is less prone to misoperation, less susceptible to damage, and does not have left-right orientation. [Means for solving the problem]

[0007] A removable slide rail comprising a fixed rail connected to a fixed member, a movable rail supported so as to be retractable relative to the fixed rail via a ball retainer that rotatably holds a ball, and a release lever for preventing the movable rail from being pulled out from the fixed rail, wherein the fixed rail is set to a length that is concealed by the movable member, whether the movable member connected to the movable rail is stored in the fixed member or when the movable member is fully extended from the fixed member, and when the movable rail is pulled out from the fixed rail together with the movable member, the release lever for preventing the movable rail from being pulled out is fixed together with the fixed rail at the tip of the fixed rail. In the slide rail remaining on the fixed member side, the anti-dislodgement release lever has at least a stopper portion and an operating portion. The stopper portion contacts a stopper projection provided on the ball retainer to stop the movement of the moving rail. The anti-dislodgement release lever is installed to be rotatable in the left-right direction, which is perpendicular to the sliding direction of the slide rail. When the anti-dislodgement release lever is rotated, the contact between the stopper portion and the stopper projection is released. The contact between the stopper portion and the stopper projection is released regardless of whether the anti-dislodgement release lever is rotated in the left-right direction or the right-handed direction. The operating portion is rotatably mounted on the fixed rail so as to protrude from both sides of the moving rail.

[0008] The operating section is integrally connected to the base of a retaining release lever having a pivot shaft, and the base is made of a rigid body that does not require elastic deformation during the operation of the retaining release lever.

[0009] The retaining lever is integrally formed from synthetic resin, and an integral metal reinforcing piece is attached to the area around the rotating shaft of the retaining lever and the stopper portion to reinforce the base. [Effects of the Invention]

[0010] Since the stopper and the stopper projection disengage when the release lever is rotated in either the left or right direction, the stopper can be released by pulling or pushing the operating part, resulting in good operability and reduced error. Furthermore, since the operating part is rotatably mounted on the fixed rail so as to protrude from both sides of the movable rail, the same slide rail can be used for both right-hand and left-hand operation, making the production and management of slide rails easier.

[0011] The operating section is integrally connected to the base of the retaining release lever, which has a pivot shaft. Since the base is a rigid body that does not require elastic deformation, there is no need to rely on the elastic deformation of the base to release the stopper function. Therefore, there is no need to set the rigidity of the elastic shifting part, making it easy to design according to the usage conditions of the slide rail, and also reducing accidental damage to the retaining release lever.

[0012] The release lever is integrally formed from synthetic resin, and an integral metal reinforcing piece is attached to the area around the rotating shaft and the stopper to reinforce the base. As a result, the release lever is not easily damaged, and since the release lever can be molded from synthetic resin without using a metal molded part, manufacturing costs and productivity are improved.

Best Mode for Carrying Out the Invention

[0014] An extractable slide rail equipped with a stopper device having excellent operability and little damage will be described below based on an example

Example

[0015] The basic configuration of the slide rail of the example will be described based on FIGS. 1 to 5 and FIG. 15 The slide rail 100 includes a fixed side rail 1 fixed to the upper surface of a fixed side rail mounting base 10 connected to the upper surface of a fixed side member E of a main body such as furniture by a connecting screw or the like, and a moving side rail 2 connected to a moving side member F slidably provided via a plurality of balls 30 rotatably held by a ball retainer 3 with respect to the fixed side rail 1, and a retaining release lever 5 provided at the tip of the fixed side (fixed side rail 1 and fixed side rail mounting base 10). In the following explanation, the diagonal downward direction on the left in Figure 1 is referred to as the drawer side (front end), the diagonal upward direction on the right is referred to as the storage side (rear end), and movement towards the drawer side or storage side is referred to as the sliding direction. Similarly, the upper and lower sides in the vertical direction of Figure 4 are referred to as the upper and lower sides, and the left and right sides in the horizontal direction are referred to as the left and right sides, respectively, because Figure 4 is a view from the storage side. Therefore, the view from the drawer side is considered correct, and the left side of Figure 4 is referred to as the right side, and the right side of Figure 4 is referred to as the left side.

[0016] The fixed rail 1 is approximately the same length as the fixed rail mounting base 10, and consists of left and right bent edges 11, 11 formed by bending both short ends (left and right ends) of a long, narrow metal plate outward in an arc shape, with ball guide grooves in the longitudinal direction (sliding direction) of the outer surface, and is formed in a roughly upward C-shape in cross-section from the base plate 12. Furthermore, when the moving rail 2 moves to the storage position, a retainer movement projection 121 is provided at a predetermined position on the base plate 12 to forcibly move the ball retainer 3 to a predetermined position even if the ball 30 slips, and a lever connection hole 122 (Figure 5) is provided for attaching the retainer release lever 5.

[0017] The fixed rail mounting base 10 to which the fixed rail 1 is fixed is formed from a top plate 101 which is approximately the same length as the base plate 12 to which the base plate 12 of the fixed rail 1 is fixed, approximately L-shaped connecting legs 102... formed by bending the left and right ends of the top plate 101 downward at a predetermined interval in the front-rear direction, and left and right deformation prevention protrusions 103... projecting upward from the top plate 101 on the left and right ends of the movable rail 2 between the connecting legs 102....

[0018] Furthermore, the top plate 101 has a lever mounting hole 104 that corresponds to the lever connecting hole 122 of the fixed rail 1, and the connecting legs 102... have fixed rail mounting holes 106... for connecting to the fixed member E. Furthermore, the left and right deformation prevention protrusions 103 are provided to prevent the moving rail 2 from deforming due to unexpected force and detaching from the fixed rail 1 (for example, when the moving rail 2 is fully extended, if a heavy object is inadvertently placed on its tip, the rear end of the moving rail 2 will lift up, causing the left and right ends of the moving rail 2 to spread apart).

[0019] In this embodiment, the movable rail 2 is approximately five times the length of the fixed rail 1 and consists of left and right bent edges 21, 21 formed by bending both short ends of a long, narrow metal plate inward into an arc shape, with ball guide grooves in the longitudinal direction (sliding direction) of the inner surface, and a cross-section that faces approximately downward from the base plate 22 and opposite the fixed rail 1.

[0020] Furthermore, the pull-out end of the circuit board 22 protrudes in the direction of the fixed rail 1, and the movable rail 2 is in its most moved position in the storage direction (the stored state of the movable rail 2, as shown in Figure 1). A rail storage stopper 220 is formed that collides with the tip of the release lever 5, stopping the sliding of the movable rail 2. A rail extension stopper 221 is formed at the storage end of the base plate 22, which protrudes in the direction of the fixed rail 1, and when the movable rail 2 is moved to its furthest position in the extension direction (extended state of the movable rail 2, as shown in Figure 2), the rear end of the ball retainer 3 comes into contact with it, stopping the sliding of the movable rail 2 along with the stopping of the ball retainer 3. Figure 5 shows that 222 is a slide regulating member, which is made of a leaf spring and, when the slide rail is assembled, contacts the upper surface of the base plate 31 of the ball retainer 3, regulating the sliding speed of the ball retainer 3 and adjusting the sliding resistance of the slide rail. By installing the slide restricting member 222, the slide becomes heavier, thus restricting excessive sliding.

[0021] The ball retainer 3 is formed in a roughly U-shape with a downward-facing cross-section from a base plate 31 made of a strip of metal plate that is a predetermined length shorter than the movable rail 2 and is sized to be inserted between the fixed rail 1 and the movable rail 2, and from left and right protruding edges 32, 32 located between the left and right bent edges 11, 11, 21, 21 of the fixed rail 1 and the fixed rail 2, and holds the balls 30... rotatably at several points in the longitudinal direction (sliding direction) of the left and right protruding edges 32, 32.

[0022] Furthermore, a retainer forced movement projection 311 is formed on the tip side of the substrate 31, corresponding to the retainer movement projection 121 of the fixed rail 1, and a retainer pull-out stopper 312 is formed on the rear end of the substrate 31, corresponding to the pull-out stopper 221 of the movable rail 2. When the movable rail 2 is pulled out to its fullest extent, the pull-out stopper 221 of the movable rail 2 comes into contact with the retainer pull-out stopper 312, and at the same time comes into contact with a part of the anti-dislodgement release lever 5, a stopper projection 313 is formed near the rear end of the substrate 31 that stops the sliding of the movable rail 2. The stopper projection 313 is formed approximately in the center between the left and right protruding edges 32, 32, is elongated in the sliding direction, and one side of the elongated side is tapered toward the storage side, with a guide arc portion 314 formed at the end on the storage side. This completes the configuration of the slide rail, and when the retaining release lever 5 is attached to the slide rail, it becomes the slide rail 100.

[0023] As shown in Figure 3, the release lever 5 for preventing detachment is integrally molded from synthetic resin material and comprises a base 51 connected to the back side of the base plate 12 of the fixed rail 1 (in this embodiment, the lower surface of the upper plate 101 of the fixed rail mounting base 10), operating parts 52, 52 connected to the pull-out side of the base 51, a stopper part 53 provided between the operating parts 52, 52, a sway stopper 54 provided on the opposite side of the stopper part 53, and lever position holding members 55, 55 formed on the outer sides of both sides of the base 51.

[0024] The base body 51 is a roughly rectangular shape that is long in the sliding direction. It is formed in a plate shape with large surface areas on the upper and lower surfaces, and a rotating hole 511 is provided on the housing side of the base body 51 that penetrates in the vertical direction. The thickness and width of the base body 51 are set to maintain rigidity so that it does not easily undergo elastic deformation. The lever position holding member 55 is provided on both the left and right sides of the storage end of the base body 51, extending outward from each side, and consists of a connecting portion 551 connected to the side of the base body 51 and projecting outward from the side, an elastically deformable portion 552 extending from the connecting portion 551 toward the pull-out side, substantially parallel to and spaced apart from the side of the base body 51, and a guide body 553 formed at the extended end of the elastically deformable portion 552. The operating section 52 is provided so as to protrude outward from both the left and right sides of the drawer-side end of the base body 51, and when installed on the slide rail, the operating section 52 is set to a length that protrudes outward in the left and right directions from the left and right bent edges 21, 21 of the moving rail 2. Furthermore, each of the storage sides of the operating section 52 is provided with an inclined surface that slopes toward the drawer side, extending from the connection point with the base 51 toward the middle of the operating section 52 in the left-right direction. This inclined surface serves as a rotation stopper surface 521 that stops the rotation of the release lever 5 (described later) at a predetermined amount.

[0025] The stopper portion 53 is located between the operating portions 52, 52 and is provided on the upper surface of the base body 51, and is formed to protrude above the base body 51. The stopper portion 53 is set to protrude to a position close to the base plate 31 of the ball retainer 3 while installed on the slide rail. The stopper portion 53 has a flat stopper surface 531 formed on the storage side that is perpendicular to the sliding direction, and the left and right sides are inclined toward the pulling direction from both ends of the stopper surface 531. The tapered side of the stopper projection 313 toward the storage side has a side inclined surface 532 on the same side (left side) that slopes outward from the center, and the other side (right side) has a side inclined guide surface 533 that slopes outward from the center, forming a roughly parallelogram shape in plan view. The stopper surface 531 is positioned at the center of the base body 51 in the shorter direction, and when assembled into the slide rail, it is positioned directly opposite the pull-out side surface of the stopper projection 313.

[0026] The brace 54 protrudes from the base 51 in the opposite direction to the stopper portion 53, and is set to be slightly lower than the protruding height of the connecting leg portion 102 when installed on the slide rail. If the base 51 deforms downward, the protruding end face of the brace (the lower face in this embodiment) comes into contact with the surface of the fixed-side member E to which the connecting leg portion 102 is fixed, thereby preventing deformation of the base 51. Furthermore, the stopper projection 313 and the stopper portion 53, which will be described later, come into contact and act as a stopper to prevent the moving slide rail 2 from coming off. However, the sway stopper 54 prevents deformation of the base 51, so when an unexpected pulling force is applied to the moving rail 2 and the stopper projection 313 of the ball retainer 3 collides with the stopper portion 53, the lower surface comes into contact with the upper surface of the fixed-side member E, preventing the stopper projection 313 from going over the stopper portion 53.

[0027] Furthermore, a concave groove 56 is provided on the upper surface of the base material 51, extending from around the rotating hole 511 to the stopper surface 53, and the reinforcing piece 6 is fitted into this groove. The reinforcing piece 6 is made of metal, manufactured by press-forming a flat steel plate, and consists of a reinforcing base plate 61 which is teardrop-shaped in plan view, a stopper reinforcing portion 62 which is bent upward from the narrowed teardrop-shaped part of the reinforcing base plate 61, a reinforcing base plate 63 which is further bent horizontally in a small way toward the opposite side of the reinforcing base plate 61 at the upper end of the stopper reinforcing portion 62, and an engaging piece 64 which is bent downward at the tip of the reinforcing base plate 63. The reinforcing base plate 61 is provided with a rotating hole 611 which penetrates in the vertical direction.

[0028] The groove 56 is formed by a rotating hole peripheral groove 561 which is formed in a teardrop shape corresponding to the reinforcing substrate 61 of the reinforcing piece 6 in a plan view, a stopper surface groove 562 which is connected to the rotating hole peripheral groove 561 and corresponds to the stopper reinforcement 62 and is provided on the stopper surface 531, a stopper groove 563 which corresponds to the reinforcing piece 63 and is provided on the upper surface of the stopper portion 53, and an engagement hole 564 which is provided downward in the stopper groove 563 and corresponds to the engaging piece 64. The reinforcing piece 6 is fitted into the groove 56 formed in this manner so as to fit into the groove 56. At this time, the engaging piece 64 is inserted into the engaging hole 564, the reinforcing piece 63 becomes substantially flush with the stopper surface 531, and the rotating hole 511 of the base body 51 and the rotating hole 611 of the reinforcing piece 6 are set to be centered. Because the stopper surface 531 is reinforced with a metal piece 6 around the rotating hole 511, the retaining release lever 5 can be prevented from being damaged by contact between the stopper surface and the stopper projection, as described later.

[0029] The retaining release lever 5, to which the reinforcing piece 6 is attached, is rotatably mounted by a fixing shaft 4 from the back surface (the lower surface in Figure 4) of the fixed rail mounting base 10, which is fixed to the base plate 12 of the fixed rail 1. The fixed shaft 4 is made of metal and is integrally formed from a cylindrical rotating shaft 41 with a diameter that fits within the rotating holes 511 and 611, a disc-shaped flange portion 42 provided on the lower surface of the rotating shaft 41 (the lower surface in Figure 4) and larger than the diameter of the rotating hole, and a cylindrical crimping portion provided on the upper surface of the rotating shaft 41 and smaller than the diameter of the rotating shaft.

[0030] Next, we will explain how to attach the retaining lever 5. While slightly elastically deforming both outer surfaces of the guide bodies 553, 553 of the release lever 5, the stopper portion 53 side (the side with the reinforcing piece 6 attached) is placed facing upwards, and the guide bodies 553, 553 are brought into contact with the inner surface of the vertical plane of the connecting legs 102, 102 at the pull-out end, from below, on the back surface of the fixed-side rail mounting base 10, so that the center of the lever mounting hole 106 provided in the fixed-side rail mounting base 10 and the center of the rotation hole 511 are aligned. Then, the fixed shaft 4 is inserted into the rotating hole 511 from below, from the crimping portion 43 side, and the crimping portion 43 is inserted into the lever mounting hole 106 above the rotating hole 511. The base plate 12 of the fixed rail 1, which is fixed to the fixed rail mounting base 10, is also provided with a lever connecting hole 122 corresponding to the lever mounting hole 106. Since the lever connecting hole 122 is formed to be larger in diameter than the lever mounting hole 106, the tip of the crimping portion 43 is positioned to face out from the lever connecting hole 122. Then, when the crimped portion 43, which is visible through the lever connection hole 122, is struck with a crimping machine, the crimped portion opens and is fixed into the lever connection hole 122. Since the flange 42 supports the base 51 around the rotating hole 511, the retaining release lever 5 is mounted on the fixed-side rail mounting base 10 so that it can rotate around the rotating shaft 41 as its central axis without coming off.

[0031] In this state, the lever 5 for releasing the locking mechanism has its operating parts 52, 52 and the stopper part 53 between the operating parts 52, 52 protruding from the drawer-side end face of the fixed-side rail mounting base 10. Furthermore, the release lever 5 is formed symmetrically on both sides except for the stopper portion 53, and the rotation shaft 41 is located in the center of the left and right sides of the top plate 101. Furthermore, the lever position holding members 55, 55 are set to be slightly wider than the left-right width of the inner surface of the vertical plane of the connecting legs 102, 102, and the elastic deformation parts 552, 552 are elastically deformed to some extent, and the guide bodies 553, 553 are set to fit into the inner surface of the connecting legs 102, 102. In the standby position where the left-right symmetrical center line of the anti-dislodgement release lever 5 coincides with the left-right symmetrical center line of the slide rail, the anti-dislodgement release lever 5 is held by the elastic deformation force of the lever position holding members 55, 55.

[0032] When the operating unit 52 is pulled out from the standby position or pushed in the storage position, the lock release lever 5 rotates as described above. At this time, the guide bodies 553, 553 are in contact with the inner surface of the vertical plane of the connecting legs 102, 102, causing the elastic deformation part 552 on the rotational direction side to be elastically deformed as it rotates. Then, the rotation stopper surface 521 of the operating part 52 on the rotation direction side comes into contact with the pull-out end surface of the connecting leg part 102, preventing the release lever 5 from rotating. When the operation of the control unit 52 is stopped from this state, the elastically deformed elastic deformation part 552 returns to its original state, and the retaining release lever 5 returns to the standby position. Thus, the lever position holding members 55, 55 act as springs to maintain the position of the release lever 5. Furthermore, since the elastic deformation part 552 is elastically deformed using the inner surface of the vertical plane of the connecting legs 102, 102, the structure is simple, the number of parts is small, and assembly and manufacturing control are easy.

[0033] Next, we will explain how to assemble the slide rail 100. A ball retainer 3, into which balls 30 are assembled, is attached to the moving rail 1, and the ball retainer 3 slides within the moving rail 1 while the balls roll along the left and right bent edges 11, 11. At this time, the stopper projection 313 of the ball retainer 3 is mounted on the storage end side of the moving rail 2, and the retainer forced movement projection 311 is mounted on the draw-out end side of the moving rail 2.

[0034] Then, the fixed rail mounting base 10, to which the retaining release lever 5 is connected and fixed to the fixed rail 1, is screw-fastened to the fixed member E, and the movable rail 2, to which the ball retainer 3 is attached, is screw-fastened to the movable member F.

[0035] Next, the storage end of the movable rail 2 is inserted from the pull-out end of the fixed rail 1, where the operating parts 52, 52 protrude. At this time, the deformation-preventing projections 103, 103 of the fixed rail mounting base 10 cover the left and right bent edges 21, 21 of the movable rail 2 from both outside sides in a way that they do not come into contact with each other, thereby preventing the movable rail 2 from falling off the fixed rail 1 as described above. Then, by inserting the fixed rail 1 from the drawer end between the opposing balls 30, 30 of the ball retainer 3, the fixed rail 1 becomes able to slide inside the ball retainer 3.

[0036] In this process, before the fixed rail 1 becomes slidable within the ball retainer 3, the inclined side guide surface 533 of the fixed rail 1 (removal lever 5) comes into contact with the guide arc portion 314 of the stopper projection 313 of the ball retainer 3. When the moving rail 2 is pushed further, the lateral inclined guide surface 533, which forms an inclined surface, moves along the arc of the guide arc 314. As a result, the lateral inclined guide surface 533 is pushed to the left (upward in Figure 13), causing the moving rail 2 to move while the release lever 5 rotates. Then, as the lateral inclined guide surface 533 passes the pull-out end of the stopper projection 313, the restoring force of the elastically deformable part 552 causes the release lever 5 to return to the standby position, and the stopper part 53 is positioned on the line of movement of the stopper projection 313. Furthermore, even if the retaining release lever 5 rotates to the right (downward in Figure 13) due to some factor, as will be described later, the retaining release lever 5 can be operated by pushing or pulling the operating part 52, so the stopper projection 313 pushes the lateral inclined surface 532 to the right (downward in Figure 13), thus avoiding the stopper projection 313.

[0037] In this state, the fixed rail 1 can slide within the ball retainer 3. As the moving rail 2 is slid further, the retainer movement projection 121 comes into contact with the retainer forced movement projection 311, and the ball retainer 3 cannot move from this contact position, causing only the moving rail 2 to slide. Then, the drawer-side end face of the stopper portion 53 comes into contact with the storage stopper 220 provided at the drawer-side end of the moving rail 2, stopping the slide, and the slide rail 100 returns to its most retracted state.

[0038] In its most retracted state, the operating sections 52, 52 are located outside the pull-out side of the fixed rail 1, and each protrudes to the left and right, outside the left and right bent edges 21 of the movable rail 2, in a position where they can be operated from below the lower surface of the movable member F connected to the movable rail 3, and are concealed from above by the movable member F.

[0039] The stopper device is formed by the stopper portion 53 of the retaining release lever 5 and the stopper projection 313 of the ball retainer 3, and the operation of the stopper function will be explained below. When the sliding rail is pulled out from its fully retracted position, the sliding rail 2 connected to the sliding rail 2 slides in the pulling direction, and at the same time, the ball retainer 3 also moves by half the distance of the sliding rail. Eventually, the rail pull-out stoppers 221, 221 of the sliding rail come into contact with the retainer pull-out stoppers 312, 312, and at the same time, the stopper projection 313 of the ball retainer 3 comes into contact with the stopper surface 531 (stopper reinforcement part 62) of the stopper part 53 of the anti-dislodgement lever 5, stopping the sliding (pulling out) of the sliding rail 2 and the ball retainer 3 (moving rail 3) (state shown in Figure 9). The stopper device functions in this way.

[0040] In this stopped state, the fixed rail 1 (fixed rail mounting base 10) and the retaining release lever 5 are located on the lower surfaces of the left and right ends of the movable member F, and are concealed by the movable member F. When removing the movable member F from the fixed member E, the tip of either the operating portion 52, 52 of the retaining release lever 5 is pulled out or pushed in the storage direction from the underside of the left and right ends of the movable member F with a fingertip. This causes the retaining release lever 5 to rotate, and the stopper surface 531 moves away from the line of movement of the stopper projection 313, thus releasing the retaining stopper function (as shown in Figures 10 and 11). Then, while maintaining this state, the movable member F (movable rail 2, ball retainer 3) can be removed from the fixed member E (fixed rail 1, fixed rail mounting base 10).

[0041] Thus, since the anti-dislodgement release lever 5 can release the anti-dislodgement stopper function whether the left or right operating part 52 is pulled in the pull-out direction or pushed in the storage direction, there is no need to prepare two types of slide rails 100, one for the right and one for the left; only two identical rails are needed, which simplifies production management and inventory management. Furthermore, since the operating part 52 can be pulled in the pull-out direction or pushed in the storage direction, it is impossible to push or pull the anti-dislodgement release lever 5 in the wrong direction, preventing misoperation and thus preventing damage caused by misoperation.

[0042] Furthermore, when the aforementioned stopper projection 313 comes into contact with the stopper surface 531, the sliding (pull-out movement) of the movable rail 2 and the ball retainer 3 (movable member F) stops. In this embodiment, the stopper surface 531 is reinforced by the stopper reinforcement portion 62 of the reinforcing piece 6, and the stopper projection 313 comes into contact with the stopper reinforcement portion 62 of the metal part of the stopper surface 531, thus preventing damage to the synthetic resin stopper portion 53. In particular, when the moving rail 2 is retracted forcefully, the stopper portion 53 is subjected to impact due to contact with the stopper projection 313. Therefore, the reinforcing piece 6, which is a metal part, is effective in preventing damage to the stopper portion 53. Furthermore, although the base body 51 is made of synthetic resin, its rigidity is set to be high so that it does not undergo elastic deformation during normal use. However, since it is made of synthetic resin, it may break when an impact force is applied. Therefore, the base body 51 is reinforced by a reinforcing piece 6 that spans from the rotation hole 511 of the base body 51 to the stopper portion 53, thereby preventing damage to the base body 51. [Industrial applicability]

[0043] As detailed above, because the slide rail is separable, the present invention can be used in a wide range of applications, such as display cases for precious metals, display cases for works of art, and sliding tops. [Explanation of symbols]
