In particular, if the protruding portion has an inclined surface that is inclined toward the front end, the protruding portion can be smoothly engaged with the engaging wall surface of the opposing rail, and the smoothness of the drawing operation of the drawer body can be further improved.

A drawer cabinet 1 with a slider S according to a preferred embodiment of the present invention will now be described with reference to the drawings. Figs. 1 to 4 show a drawer cabinet 1 of the present invention. In the illustrated example, the drawer cabinet 1 is open from the front. The frame body 2 and the drawer body 3 that can be accommodated in the frame body 2 are freely detachable. As shown in FIGS. 1 to 4 and 5 to 9, the drawer slider S includes a first slide rail 12 and a system. The second sliding rail 14 is slidably engaged with the first sliding rail 12 and attached to the outer side surfaces of the drawer body 3; and the locking means 20 is attached to the inner wall surface of the frame body 2; When the drawer body 3 is pulled into the casing 2, the first and second slide rails 12 and 14 overlap each other, and the first and second slide rails 12 and 14 are locked to each other.

In the illustrated example, the first slide rail 12 is an outer slide rail, and the second slide rail 14 is an inner slide rail. However, the first slide rail 12 may be the inner side, and the second slide rail 14 may be the outer side. Further, in the illustrated example, the intermediate slide rail 16 is provided between the first and second slide rails 12 and 14, but the intermediate slide rail 16 may be omitted. Moreover, the first and second slide rails 12 and 14 have points It is not attached to the mounting bolt holes 12H and 14H of the housing 2 and the drawer body 3 (see, in particular, FIG. 8).

The drawer slide S on one side will be described in detail below, and the drawer slide S on the other side is identical and symmetrically constructed on the side.

The first slide rail 12, the second slide rail 14, and the intermediate slide rail 16 are each formed of a metal structural member formed of a channel-shaped steel having a U-shaped cross section, and may be made of a material other than metal. The first slide rail 12 and the intermediate slide rail 16 are arranged by the sliding members disposed between the side walls 12S and 16S so that the overlapping surfaces 12W and 16W overlap each other (a part of the ball is exposed from both sides, and most of the balls are held at intervals) The plate-like member 18A is slidably fitted, and the second slide rail 14 is disposed between the side walls 14S and 16S by the overlapping surface 14W facing the opposite side of the overlapping surface 16W of the intermediate slide rail 16 ( The same structure as the sliding member 18A) 18B is slidably fitted to each other (see Figs. 5, 6 and 9, and particularly Fig. 9). Between the first and second slide rails 12, 14 and the intermediate slide rail 16, the drawer main body 3 can be smoothly moved in and out, and is held loose.

As shown in FIG. 5 and FIG. 11, the locking means 20 is composed of a metal or rigid plastic frame 30 fixedly attached to the deep end of the first sliding rail 12, and a sliding block 40 with a guiding groove. As will be described later, it is slidably held by the holder 30, and is detachably coupled to the front end portion of the second slide rail 14. When the drawer body 3 is pulled in (closed), the drawer body 3 and the second slide rail are attached. 14 moves together deep (refer to FIG. 11(B)); and a lever-shaped locking member 50. The rocking pin 52 is freely supported by the deep end of the frame 30, and has a locking pin 54 that is engaged with the guiding groove 46 of the sliding block 40. Since the slider 40 is attached to the inside of the block carrier 42 slidably held on the frame 30 (corresponding to the back side of the paper of FIG. 5 and FIG. 6), it is not recognized in FIG. 5 and FIG. In Figure 11 (B). In the illustrated example, although the locking member 50 laterally displaces the locking pin 54 by the rocking of the locking member 50, if the locking pin 54 can be displaced in the width direction of the frame 30, even if it is not a lever shape, .

As shown in FIGS. 5 and 11, the frame 30 has a horizontal piece 34 disposed at one end of the frame body 32 and having a substantially T-shape. The horizontal piece 34 is embedded in the deep end opening of the first slide rail 12, and the frame body is further 32 is fixed by an appropriate means (not shown), whereby the frame 30 is fixed to the first slide rail 12.

As shown in Fig. 11, in particular, as shown in Fig. 11(B), the block carrier 42 is formed by joining two carrier half portions 42H, and the block carrier 42 is slidably slidably formed by the two carrier half portions 42H. The frame body 32 is fitted to the frame body 32 and guided along the longitudinal direction of the first slide rail 12. As shown in Fig. 11(B), the slider 40 of the guide groove is fixedly mounted on one of the carrier halves in the space of the block carrier 42. Therefore, when the block carrier 42 is guided along the longitudinal direction of the first slide rail 12 along the frame 30, the slide block 40 of the guide groove advances and retreats with respect to the rocking pin 52 of the lock member 50.

The block carrier 42 typically applies a potential energy in a direction away from the locking member 50 by a pair of springs 44 suspended from one of the two sides of the pair of blade-like spring retaining tabs 42P and the frame extending from the frame 30. One of the two sides of the body 32 Between the spring fixing pieces 32P.

As shown in FIG. 13, the guide groove 46 of the sliding block 40 has a wide opening 46O at the rear end, and further has an upper locking surface 46L for engaging with the locking pin 54 of the locking member 50 when the drawer body 3 is pulled in. , the opening 46O is connected to lock the locking member 50; the retracting side inducing surface 46R is pulled back while being pulled into the drawer body 3, and the locking pin 54 of the locking member 50 is guided to be locked. The surface 46L and the forward side induction surface 46F are pulled back while the drawer body 3 is opened, and the lock pin 54 of the lock member 50 is detached from the lock surface 46L, and then advanced to the opening 46O. In FIG. 13, although the symbols 46R and 46F are not shown, the symbols of "a, b, c, and d" are attached to the order in which the retreating side inducing surface 46R contacts the lock pin 54, and the latch is formed on the advancing side inducing surface 46F. The notes in the order of contact 54 indicate the symbols of "a, b, c". Further, the induction surfaces 46Rd and 46Fb are formed to be elongated a little longer, and the second slide rail 14, that is, the lock pin 54, can be displaced in a direction in which the position closer to the closed state of the drawer body 3 is further closed.

When the second slide rail 14 and the slide block 40 of the guide groove are connected to each other, the rail block connecting means 60 is released, and as shown in FIGS. 10 and 11 (A) and (C), the rail block is connected. The means 60 is composed of a member in which the claw member 62 is fixedly attached to the inner surface of the second slide rail 14 (the surface facing the intermediate slide rail) (see FIG. 10); and the hook member 64 is attached to the block carrier. 42 front end (one end opposite to the side of the lock member 50) (refer to Figs. 11 (A), (C)). As shown in Fig. 11(C), the hook member 64 has a guide pin 64P at its free end, which is engaged. The guide groove 32G of the frame body 32 of the frame 30 is formed, and the guide groove 32G is formed at a position where the block carrier 42 retreats from the locking member 50, as shown by the solid line in FIG. 5 and FIG. 11(A) and FIG. 11 ( C) One of the dotted chain lines, the opening of the hook of the hook member 64 is inclined forward (the direction opposite to the locking member), and the block carrier 42 is advanced in the direction of the upward locking member 50, as shown in FIG. (C) The dotted line of the hook member 64 becomes lateral (the direction of the width of the frame 30) as indicated by the broken line on the upper side, and the hook member 64 is displaced as the block carrier 42 advances and retracts. That is, the guide groove 32G is formed in a curved shape toward the one side of the frame body 32 at the retracted position of the block carrier 42, and is formed in a straight line shape before the block carrier 42 is advanced. The equal curve portion and the straight portion are continuous.

Therefore, when the drawer body 3 is pushed into the frame 2 (moving for closing), the second slide rail 14 is also pushed in (advanced) and attached to the outside of the second slide rail 14 (the intermediate slide rail 16 faces each other) The claw member 62 is also advanced (moving in the direction of the arrow F of FIG. 10), and the claw member 62 enters the hook opening of the hook member 64 attached to the block carrier 42, via which the block carrier 42 Also pushed (advanced). Further, if the drawer body 3 is opened (retracted) (moved in the direction of the arrow R in Fig. 10), the claw member 62 of the rail block connecting means 60 and the hook member 64 are held, and the block carrier 42 is also Retreating, if the pin 64P of the hook member 64 attached to the block carrier 42 hooks the curved portion of the guide groove 32G, the hook opening is opened forward to allow the claw member 62 of the second slide rail 14 to be released from the hook member 64. Opening, the second slide rail 14 can be released from the block carrier 42, and the block carrier 42 can be left on the first slide rail 12 and then Retreat.

The second slide rail 14 and the intermediate slide rail 16 are detached from the end portion of the intermediate slide rail 16 by the fall prevention member 14RS (only a part of which is shown in FIG. 10) provided on the second slide rail 14 side. The horizontal direction of the member 14RS is prevented from being engaged with the projections (not shown) of the grooves (not shown), and is prevented from coming off, but the fall prevention member 14RS can be rearward from the end of the intermediate slide rail 16 (the drawer body 3 is pulled out) Or the backward direction is offset and at the exposed position, the hand is displaced in the width direction of the rail to release the fall prevention function. Further, the intermediate slide rail 16 is at the foremost end position (the most push-in position), and the front end thereof is fitted to the stopper 32PS of the spring support 32P provided at the rear end of the frame 30 (refer to FIG. 5), and the second slide rail 14 is further provided. Over the forward end of the intermediate slide rail 16, the jaw member 62 of the track block coupling means 60 advances to snap into the hook member 64 on the frame 30.

Next, the opening and closing operation of the drawer cabinet 1 is explained. To close the drawer cabinet 1, if it is pushed in the direction of closing the drawer body 3 as shown in Figs. 2 and 5, the second slide rail 14 is slid into the middle through the intermediate slide rail 16. And accommodated in the first slide rail 12, and the second slide rail 14 is connected to the block carrier 42 of the locking means 20 via the rail block connecting means 60 (see FIGS. 12(A) and (B)). The second slide rail 14 advances further, that is, the block carrier 42 moves the slide block 40 to the deep end side of the first slide rail 12 (see FIG. 12(C)).

Thus, if the slider 40 is advanced, the lock pin 54 of the lock member 50, that is, the opening 460 of the guide groove 46 of the slide block 40 shown in Figs. 13(A) and (B), via the reverse side induction faces 46Ra, 46Rb, 46Rc By the shaking of the lock member 50, When the side is abutted, one side is snapped into the extension of the receding side inducing surface 46Rd. If the hand is removed from the drawer body 3, the sliding block 40 is retracted in the direction of opening the drawer body 3 by the spring 44. Therefore, the locking pin 54 of the locking member 50 The locking surface 46L is engaged with the guide groove 46 of the sliding block 40, and the sliding block 40, that is, the second sliding rail 14 is retracted in the backward direction of the drawer body 3 (the direction in which the drawer body is opened) is locked (refer to FIG. 6).

Next, in order to open the drawer cabinet 1, once against the spring 44, the drawer body 3 is pushed in the pull-in (closed) direction (forward direction), and the slider block 40 is displaced to the first slide rail 12 via the second slide rail 14. The deep end side, that is, the lock pin 54 of the lock member 50 is as shown by "b" of FIG. 13(C), and the lock surface 46L of the guide groove 46 of the slide block 40 is pulled to the side by the advancing side induction surface 46Fa. One side enters the extension of the advancing side inducing surface 46Fb. Therefore, if the drawer body 3 is pulled out thereafter, that is, the sliding block 40 is moved in the pulling-out direction via the second sliding rail 14, the locking pin 54 of the locking member 50 is guided. The groove 46 is advanced from the opening 46O of the guide groove 46 while being advanced to the side induction surface 46Fc. Therefore, the drawer body 3 can be pulled out from the frame 2.

The drawer slide S of the present invention includes a tilt preventing means (or a slack preventing means for preventing slack of the second slide rail of the second slide rail 14) 70, in a state where the first and second slide rails 12, 14 are overlapped, The inclination of the second slide rail 14 with respect to the first slide rail is prevented.

As shown in FIGS. 9 and 21, the inclination preventing means 70 is constituted by a projection 72 which is formed on the front end side of the second slide rail 14 and faces toward the phase For the outer side (the side opposite to the drawer body 3, that is, the face of the intermediate slide rail 16 in the illustrated case), the protrusion is formed; and the engagement wall surface 74 is for the first and second slide rails 12 And the 14th overlap state is engaged with the protrusion 72, and the second slide rail 14 is engaged with the engagement wall surface 74 by the protrusion wall 72 with respect to the flat wall surface of the track on the outer surface of the second slide rail 14, thereby preventing the first 1 and the second slide rails 12, 14 are close to each other, thereby preventing slack between the rails.

In the illustrated embodiment, the second slide rail 14 is fitted to the first slide rail 12 via the intermediate slide rail 16, so that the flat engagement wall surface 74 of the projection portion 72 of the second slide rail 14 is engaged with the intermediate slide rail. The end of the inner surface (the surface facing the second slide rail 14).

Further, in the illustrated embodiment, in particular, as shown in Fig. 21, the projection 72 of the second slide rail 14 is formed by a portion of the rail wall surface formed in a substantially L shape, and the engagement surface 72E of the L-shaped projection portion is formed. An inclined surface that gradually deviates from the opposite flat engagement wall surface 74 is formed. Therefore, as is apparent from Fig. 21, the entire engagement surface 72E of the projection portion 72 is not in contact with the engagement wall surface 74, but is in line contact in the width direction of the rail. This is the rail in which the second slide rail 14 is fitted, as shown in the figure. In the illustrated form, the intermediate slide rail 16 is prevented from slacking with low resistance, and therefore, the pull-in resistance of the drawer body 3 is not increased.

When the second slide rail 14 is not used, and the second slide rail 14 is directly fitted to the first slide rail 12, the projection 72 for preventing the tilt of the second slide rail 14 is engaged with the first slide rail 12. The flat side of the face side engages the wall surface 74.

As described above, the drawer slide S of the present invention includes the inclination preventing means 70 for preventing the second slide rail 14 from slacking with respect to the first slide rail 12 when the first and second slide rails 12, 14 are overlapped. Therefore, in order to pull out (open) the drawer body 3, even if it is not in the center of the front side of the drawer body 3, as shown by an arrow Y in Fig. 22, the drawer body 3 is pushed into the left or right position, and the drawer body 3 is still pushed. The inclination of pushing the push-in side only (see FIG. 22) does not occur, and the state in which the right and left sides of the drawer body 3 are parallel is pushed in, and the lock of the left and right drawer slides S can be surely released. Therefore, the drawer cabinet 1 can be surely opened, and the damage of the drawer slider S caused by the inclination of the drawer body 3 can be effectively prevented.

Further, when the tilt preventing means 70 is constituted by the protruding portion 72 provided on the distal end side of the second slide rail 14, the tilt preventing projection portion 72 is pulled out from the opposite engaging wall surface 74 when the drawer body 3 is pulled out. The direction (opening direction) deviates, and since the second slide rail 14 returns to the slack with respect to the first slide rail 12, the drawer body 3 is pulled out without the resistance of the tilt preventing means 70, and can be smoothly performed.

In addition, when the slack preventing projections 72 are formed by the rail wall surface of the second slide rail 14, that is, when the second slide rail 14 is integrally formed, the tilt preventing means 70 is easily formed, and thereafter, the projections are formed. By the formation of the projections 72, the projections 72 are elastically engaged with the opposing engagement wall faces 74, and the drawer body 3 can be smoothly pulled without any resistance. In particular, if the protruding portion 72 has a slanting engaging surface 72E, the protruding portion 72 That is, the smooth engagement with the opposing engagement wall surface 74 can further improve the smoothness of the drawer body 3 during the pulling operation.

(industrial availability)

According to the present invention, the drawer slide member having the locking means for unlocking the lock in the pull-in direction in one pull-in direction, in order to open the drawer body, is not in the center of the drawer body, but is located at a position offset from either of the center Pushing in, can still untie the lock of the sliding parts on both sides, can effectively pull out the drawer body, and has high industrial utilization.
