Description

The present invention locks a drawer which is slidably supported in a housing through a slide rail and opens and closes, and locks the drawer in a closed state. When the drawer is opened, the drawer is pushed in the closing direction to release the lock. The present invention relates to an improved drawer cabinet and a drawer slider used for the drawer.

A drawer slider used in a drawer cabinet with a slider is mounted between the housing and the drawer body that is stored in the housing so that it can be freely inserted and removed. The drawer body can be pulled into the housing and the drawer body can be pulled out of the housing. In addition, the drawer body has a function of locking the drawer body to the housing in a state where the drawer body is pulled into the housing.

  This type of drawer slider is provided between the both side walls of the drawer body and the inner wall facing the casing. Each slider has a first slide rail attached to the inner wall surface of the casing, and the first slide rail. A second slide rail attached to a drawer body that slidably engages with the slide rail and moves freely in and out of the housing, and the first and second slide rails when the drawer body is pulled into the housing. Locking means for locking each other (see Patent Documents 1 and 2).

  Generally, in order to pull out the drawer body, the center of the front wall of the drawer body is pushed in to release the slider lock, but at the position shifted to the left or right from the center of the drawer body, the front wall of the drawer body is pushed in. May attempt to release lock.

  On the other hand, the first and second slide rails are loosely spaced in the width direction of the drawer body so that the drawer body can be smoothly slid with respect to the housing and the drawer body can be inserted and removed without resistance. Are fitted. For this reason, in order to open the drawer body, when the drawer body is pushed in at a position shifted to the left or right instead of the front center of the drawer body (see arrow Y in FIG. 22), the second slide rail is the first slide rail. Since the drawer body is tilted due to looseness with respect to the slide rail (see reference numeral 3 in FIG. 22), the slider on the pushing operation position side releases the lock, but the slider on the opposite side is not pushed in enough. The slider lock may not be released. In such a state, the drawer body cannot be pulled out, and an excessive force is applied to the slider on the opposite side, which may damage the slider.

One problem to be solved by the present invention is to ensure that the sliders on both sides are locked even if the drawer body is pushed not at the center of the drawer body but at a position shifted to the left or right from the center to open the drawer body. It is an object of the present invention to provide a drawer cabinet with a slider that can be released to effectively pull out a drawer body.

  Another problem to be solved by the present invention is to ensure that the sliders on both sides are locked even if the drawer body is pushed not at the center of the drawer body but at a position shifted to the left or right from the center to open the drawer body. It is an object of the present invention to provide a drawer slider that can be released to effectively pull out a drawer body.

According to a first aspect of the present invention, there is provided a first slide rail that is attached to opposing inner wall surfaces of a housing, and a drawer that is slidably engaged with the first slide rail and moves freely in and out of the housing. A pair of sliders each including a second slide rail attached to the main body is provided, and each slider has the first and second slide rails in a state where the drawer main body is pulled into the housing and the first and second slide rails are overlapped. A locking means for locking the two slide rails together, and when the drawer body is pulled out, the lock means pushes the drawer body in a closing direction so that the second slide rail is moved relative to the first slide rail. in pushing the slider with drawers cabinet is obtained so as to release the lock is displaced in a direction, each slider, said first and second slide To provide a slider with drawers cabinet, characterized in that Lumpur said second slide rail in a state polymerized and a tilting preventing means for preventing the inclined with respect to the first slide rail is there.

  In the first problem-solving means of the present invention, the tilt preventing means includes a protrusion provided so as to protrude toward the rail facing the second slide rail on the front end side of the second slide rail. The protrusion is engaged with the engagement wall surface of the rail opposite to the second slide rail in the overlapping state of the first and second slide rails, and the second slide rail is inclined. It is preferable to prevent it.

  In this case, when the second slide rail is directly fitted to the first slide rail, the inclination preventing protrusion provided on the second slide rail is on the inner surface side of the first slide rail. When the second slide rail is engaged with the second slide rail via the intermediate slide rail, the protrusion of the second slide rail is It is engaged with the engagement wall surface on the inner surface side.

  The protrusion of the second slide rail can be formed by punching a part of the rail wall surface into a substantially L shape. In this case, the engaging surface of the L-shaped protrusion is the engagement of the opposing rail. It is preferable to have an inclined surface that gradually separates from the wall surface toward the front end (the end portion on the front side of the drawer main body).

  According to a second aspect of the present invention, there is provided a first slide rail to be attached to an inner wall surface of a housing, and a drawer main body that slidably engages with the first slide rail and moves in and out of the housing. And a lock that locks the first and second slide rails in a state where the drawer body is pulled into the housing and the first and second slide rails are overlapped with each other. The lock means, when pulling out the drawer body, pushes the drawer body in the closing direction and displaces the second slide rail in the pushing direction to release the lock. In the drawer slider as described above, the second slide rail is the first slide rail in a state where the first and second slide rails are overlapped. And to provide a drawer slider, characterized in that it comprises a tilting preventing means for preventing the inclined with respect.

  In the second problem-solving means of the present invention, the inclination preventing means is formed from a protrusion provided to protrude toward the rail facing the second slide rail on the front end side of the second slide rail. The protrusion is engaged with the engagement wall surface of the rail opposite to the second slide rail in the overlapping state of the first and second slide rails, and the second slide rail is inclined. It is preferable to prevent it.

  In this case, when the second slide rail is directly fitted to the first slide rail, the inclination preventing protrusion provided on the second slide rail is on the inner surface side of the first slide rail. When the second slide rail is engaged with the second slide rail via the intermediate slide rail, the inclination preventing protrusion of the second slide rail is The intermediate slide rail engages with the rail engaging wall surface on the inner surface side.

  The protrusion of the second slide rail can be formed by punching a part of the rail wall surface into a substantially L shape. In this case, the engaging surface of the L-shaped protrusion is the engagement of the opposing rail. It is preferable to have an inclined surface that gradually separates from the wall surface toward the front end (the end portion on the front side of the drawer main body).

  According to the present invention, as described above, the slider prevents the second slide rail from tilting with respect to the first slide rail when the first and second slide rails are overlapped. Even if the drawer body may be pushed to the left or right rather than the center of the front of the drawer body to open the drawer body, the drawer body is only on the push side. Without tilting to be pushed in, it is pushed in while the left and right sides of the drawer body are kept parallel, and the locks of both the left and right sliders can be reliably released, so the drawer is surely opened. It is possible to effectively prevent damage to the slider due to the inclination of the drawer body.

  Further, since the inclination preventing means is composed of a protrusion provided on the front end side of the second slide rail, when the drawer main body is pulled out, the inclination preventing protrusion is separated from the engaging wall surface of the opposite rail. Therefore, since the second slide rail recovers looseness relative to the first slide rail, the drawer operation of the drawer body can be smoothly performed without receiving the resistance of the tilt prevention means.

  Furthermore, if the protrusion for preventing tilting is formed from the wall surface of the second slide rail, it is formed integrally when the slide rail is formed, so that it is easy to form the tilt preventing means, and the protrusion is driven out. If formed by the above, the protrusion elastically engages with the engaging wall surface of the opposing rail, and the drawing operation of the drawer body can be smoothly performed without resistance. In particular, when the projecting protrusion has an inclined surface inclined toward the front end, the protrusion can smoothly engage with the engaging wall surface of the opposing rail, and the smoothness of the drawing operation of the drawer body can be further improved. can do.

A drawer cabinet 1 with a slider S according to a preferred embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 to 4 show the drawer cabinet 1 of the present invention. 1 includes a housing 2 whose front surface is open and a drawer body 3 that is housed in the housing 2 so as to be freely inserted and removed. The drawer slider S is shown in FIGS. 1 to 4 and FIGS. 5 to 9. In addition, a first slide rail 12 attached to opposite inner wall surfaces on both sides of the housing 2, and a second slide rail 12 slidably engaged with the first slide rail 12 and attached to both outer side surfaces of the drawer body 3. The first and second slide rails 12 and 14 are overlapped to lock the first and second slide rails 12 and 14 to each other when the slide rail 14 and the drawer body 3 are pulled into the housing 2. And a lock means 20.

  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, but the first slide rail 12 is the inner side and the second slide rail 14 is the outer side. There may be. 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. The first and second slide rails 12 and 14 have holes 12H and 14H for mounting bolts used for mounting to the housing 2 and the drawer main body 3, respectively (see particularly FIG. 8).

  Hereinafter, the drawer slider S on one side will be described in detail, but the drawer slider S on the other side is the same as the one side, but is configured symmetrically.

  The first slide rail 12, the second slide rail 14, and the intermediate slide rail 16 are all made of a metal structural member such as a grooved steel having a U-shaped cross section, but are made of a material other than metal. There may be. The first slide rail 12 and the intermediate slide rail 16 include a sliding member disposed between the side walls 12S and 16S so that the webs 12W and 16W are overlapped (a large number so that a part of the ball is exposed from both sides). The second slide rail 14 is slidably fitted by a plate-like member 18 </ b> A that is held at intervals, and the second slide rail 14 has a web 14 </ b> W that faces away from the web 16 </ b> W of the intermediate slide rail 16. As shown in FIGS. 5, 6 and 9, the sliding members (similar to the sliding member 18 </ b> A) 18 </ b> B disposed between the side walls 14 </ b> S and 16 </ b> S are slidably fitted to each other (FIGS. 9). The first and second slide rails 12 and 14 and the intermediate slide rail 16 are fitted to each other with a slack so that the drawer body 3 can be inserted and removed smoothly.

  As shown in FIGS. 5 and 11, the locking means 20 includes a metal or rigid plastic frame 30 fixedly attached to the back end of the first slide rail 12 and, as will be described later, on the frame 30. Slidably held at the tip of the second slide rail 14 and detachably coupled to the back together with the drawer body 3 and the second slide rail 14 when the drawer body 3 is retracted (closed). The slide block 40 with the guide groove that moves (see FIG. 11B) and the lock pin 54 that is swingably supported at the back end of the frame 30 by the swing pin 52 and engages with the guide groove 46 of the slide block 40. And a lever-like lock member 50 having Since the slide block 40 is attached to the inside of the block carrier 42 slidably held by the frame 30 (corresponding to the back side of the paper surface of FIGS. 5 and 6), it can be recognized in FIGS. Although not possible, it is shown in FIG. In the illustrated example, the lock member 50 is configured to displace the lock pin 54 in the lateral direction by swinging the lock member 50. However, if the lock pin 54 can be displaced in the width direction of the frame 30, the lever It does not have to be in the shape.

  As shown in FIGS. 5 and 11, the frame 30 has a substantially T-shaped configuration in which a horizontal piece 34 is integrally provided at one end of a frame main body 32, and the horizontal piece 34 is formed on the first slide rail 12. The frame main body 32 is fitted into the rear end opening, and 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, particularly FIG. 11B, the block carrier 42 is formed by joining two carrier halves 42H. The block carrier 42 has a space formed by the two carrier halves 42H. The frame body 32 is slidably fitted and guided along the frame body 32 in the longitudinal direction of the first slide rail 12. As shown in FIG. 11B, the slide block 40 with guide grooves is fixedly attached to one carrier half in the space of the block carrier 42. Therefore, when the block carrier 42 is guided in the longitudinal direction of the first slide rail 12 along the frame 30, the slide block 40 with the guide groove moves forward and backward with respect to the swing pin 52 of the lock member 50.

  The block carrier 42 is supported by a pair of springs 44 latched between a pair of blade-like spring retaining pieces 42P on both sides thereof and a pair of spring retaining pieces 32P extending on both sides of the frame body 32 of the frame 30. Usually, it is urged away from the lock member 50.

  As shown in FIG. 13, the guide groove 46 of the slide block 40 has a wide opening 46O at the rear end, and further engages with the lock pin 54 of the lock member 50 when the drawer body 3 is retracted. A lock surface 46L that continues to the opening 46O so as to lock the lock member 50, and a retracting retraction side guide that retracts while narrowing the lock pin 54 of the lock member 50 to guide the lock surface 46L when the drawer body 3 is retracted. When the drawer main body 3 is opened, the surface 46R and the lock pin 54 of the lock member 50 are retracted so as to be disengaged from the lock surface 46L, and then moved forward to be guided to the opening 46O. In FIG. 13, reference numerals 46R and 46F are not provided, but the backward guide surface 46R is marked with "a, b, c, d" in the order in which the lock pins 54 come into contact, and the forward guide surface 46F. Are indicated by adding “a, b, c” in the order in which the lock pins 54 come into contact with each other. The guide surfaces 46Rd and 46Fb are extended so that the second slide rail 14, that is, the lock pin 54 can be displaced slightly in the closing direction from the position where the drawer body 3 is maintained in the closed state. Is formed.

Rail block connecting means 60 for connecting and releasing the second slide rail 14 and the slide block 40 with the guide groove is provided, and this rail block connecting means 60 is shown in FIGS. As shown in (C), the claw member 62 (see FIG. 10) fixedly attached to the inner surface (the surface facing the intermediate slide rail) of the second slide rail 14 and the front end (lock member) of the block carrier 42 And a flange member 64 (see FIGS. 11A and 11C) attached to an end opposite to the side with respect to 50. As shown in FIG. 11C, the flange member 64 has a guide pin 64P that engages with a guide groove 32G provided in the frame body 32 of the frame 30 at the free end of the swing, and the guide groove 32G. In the position where the block carrier 42 is retracted from the lock member 50, as shown by the solid line in FIG. 5 and FIG. 11 (A) and the alternate long and short dash line in FIG. In the position where the block carrier 42 is advanced toward the lock member 50, as shown by the dotted line on the upper side of FIG. 11C , the heel opening of the heel member 64 is opened. Is formed sideways (in the width direction of the frame 30) so as to displace the flange member 64 as the block carrier 42 advances and retreats. That is, the guide groove 32G is formed in a curved shape toward one side of the frame main body 32 at the retracted position of the block carrier 42, and is formed linearly from the middle of the frame main body 32 at the advanced position of the block carrier 42. The curved portion and the straight portion are continuous.

  Therefore, when the drawer body 3 is pushed into the housing 2 (moved so as to close) and the second slide rail 14 is also pushed (advanced), the outer surface of the second slide rail 14 (to the intermediate slide rail 16). The claw member 62 attached to the opposite surface also moves forward (moves in the arrow direction F in FIG. 10), and the claw member 62 enters the heel opening of the heel member 64 attached to the block carrier 42, The block carrier 42 is also pushed in (moves forward) through the flange member 64. Further, when the drawer body 3 is pulled out and opened (retracted) (moves in the arrow direction R in FIG. 10), the block carrier is maintained while the connection between the claw member 62 and the flange member 64 of the rail block connecting means 60 is maintained. 42 also moves backward, but when the pin 64P is applied to the curved portion of the guide groove 32G, the heel member 64 attached to the block carrier 42 opens forward so that the second slide rail 14 The claw member 62 can be released from the flange member 62 and the second slide rail 14 can be disengaged from the connection with the block carrier 42 and can be retracted while the block carrier 42 remains on the first slide rail 12.

  The second slide rail 14 and the intermediate slide rail 16 are a retaining member 14RS (only a part of which is shown in FIG. 10) provided on the second slide rail 14 side and the end of the intermediate slide rail 16. The retaining members 14RS are mutually prevented by meshing with protrusions (not shown) that are provided in the portions and are engaged with the lateral engaging grooves (not shown) of the retaining members 14RS. It is possible to release the retainer by manually displacing it in the width direction of the rail at a position that is exposed rearwardly from the end of the rail (extracting direction or retracting direction of the drawer body 3). The intermediate slide rail 16 has a front end abutted against a stopper 32PS provided on a spring receiver 32P at the rear end of the frame 30 at the frontmost end position (most pushed-in position) (see FIG. 5). The slide rail 14 then advances beyond the front end of the intermediate slide rail 16 and advances so that the claw member 62 of the rail block connecting means 60 engages with the flange member 64 on the frame 30.

  Next, the opening / closing operation of the drawer cabinet 1 will be described. To close the drawer cabinet 1, as shown in FIGS. 2 and 5, the drawer body 3 is pushed in the closing direction, and the second slide rail 14 is moved to the intermediate slide rail 16 as shown in FIG. The second slide rail 14 is connected to the block carrier 42 of the locking means 20 via the rail / block connecting means 60 (FIG. 12 ( When the second slide rail 14 further advances, the slide block 40 is moved to the back end side of the first slide rail 12 via the block carrier 42 (see FIG. 12C). ).

  When the slide block 40 moves forward in this way, the lock pin 54 of the lock member 50 moves from the opening 46O of the guide groove 46 of the slide block 40 shown in FIGS. 13A and 13B to the backward side guide surfaces 46Ra, 46Rb, 46Rc. Then, the lock arm 50 engages with the extended portion of the backward guide surface 46Rd while being moved closer by the swinging of the lock arm 50. However, when the hand is released from the drawer body 3, the slide block 40 opens the drawer body 3 by the spring 44. Therefore, the lock pin 54 of the lock member 50 engages with the lock surface 46L of the guide groove 46 of the slide block 40, and the slide block 40, that is, the second slide rail 14, moves backward in the drawer body 3 (the drawer body is It is locked to be returned in the opening direction (see FIG. 6).

  Next, in order to open the drawer cabinet 1, the drawer body 3 is once pushed against the spring 44 in the retracting (closed) direction (forward direction) and the slide block 40 is moved through the second slide rail 14 to the first slide. When displaced toward the rear end side of the rail 12, the lock pin 54 of the lock member 50 moves from the lock surface 46L of the guide groove 46 of the slide block 40 to the forward guide surface 46Fa, as indicated by “b” in FIG. , The extension portion of the forward guide surface 46Fb enters into the extended portion while being pulled out by the first slide body 40. Thereafter, when the drawer body 3 is pulled out, the slide block 40 is moved in the pull-out direction via the second slide rail 14, and thus the lock member. The 50 lock pins 54 are removed from the opening 46O of the guide groove 46 while being further offset by the forward guide surface 46Fc of the guide groove 46. To. Therefore, the drawer body 3 can be pulled out from the housing 2.

  The drawer slider S according to the present invention is provided with an inclination preventing means (or a first anti-inclination means) for preventing the second slide rail 14 from inclining with respect to the first slide rail in a state where the first and second sliders 12 and 14 are overlapped. (Slack prevention means 70) for preventing the second slide rail 14 from loosening with respect to the second slide rail.

  As shown in FIGS. 9 and 21, the inclination preventing means 70 is provided on the front end side of the second slide rail 14 on the outer surface side (opposite to the drawer body 3, that is, opposite to the intermediate slide rail 16 in the illustrated case). And the second slide so that the protrusion 72 is engaged in a superposed state of the first and second slide rails 12, 14. The second slide rail 14 is composed of a flat engagement wall surface 74 of the rail facing the outer surface of the rail 14, and the first and second slide rails are engaged by the engagement of the projection 72 and the engagement wall surface 74. By preventing 12 and 14 from approaching each other, loosening between these rails is prevented.

  In the illustrated embodiment, since the second slide rail 14 is fitted to the first slide rail 12 via the intermediate slide rail 16, the flat engagement with which the protrusion 72 of the second slide rail 14 is engaged is shown. The mating wall surface 74 is provided at the end of the intermediate slide rail on the inner surface (the surface facing the second slide rail 14) side.

  In the illustrated embodiment, particularly, as shown in FIG. 21, the protrusion 72 of the second slide rail 14 is formed by punching a part of the rail wall surface into a substantially L shape. The engaging surface 72E of the protrusion is an inclined surface that gradually separates from the opposing flat engaging wall surface 74. Therefore, as shown in FIG. 21, the protrusion 72 is not in contact with the engagement wall surface 74 but is in line contact with the rail in the width direction. In the embodiment shown in the figure, the second slide rail 14 is fitted, and the intermediate slide rail 16 is prevented from loosening with a low resistance, so that the pull-in resistance of the drawer body 3 is not increased.

  When the second slide rail 14 is directly fitted to the first slide rail 12 without using the intermediate slide rail 16, the tilt prevention protrusion provided on the second slide rail 14 is used. The part 72 is engaged with the flat engaging wall surface 74 on the inner surface side of the first slide rail 12.

  As described above, the slider S of the present invention prevents the second slide rail 14 from loosening with respect to the first slider 12 in a state where the first and second slide rails 12 and 14 are overlapped. Since the means 70 is provided, in order to pull out (open) the drawer body 3, the drawer body 3 is not at the front center of the drawer body 3 but at a position shifted to either the left or right as shown by the arrow Y in FIG. The drawer body 3 is not tilted so that only the pushing side is pushed in (see FIG. 22), and the drawer body 3 is pushed in while the left and right sides of the drawer body 3 are kept parallel. Therefore, the locks of both the left and right sliders S can be reliably released. Therefore, the drawer cabinet 1 can be opened reliably, and damage to the slider S due to the tilt of the drawer body 3 can be effectively prevented.

  In addition, when the tilt preventing means 70 includes the protrusion 72 provided on the front end side of the second slide rail 14, when the drawer body 3 is pulled out, the protrusion 72 for tilt prevention has an opposing engagement wall surface. Accordingly, the second slide rail 14 recovers the looseness with respect to the first slide rail 12, so that the drawer operation of the drawer body 3 reduces the resistance of the inclination preventing means 70. It can be done smoothly without receiving it.

  Further, if the protrusion 72 for preventing looseness is formed by stamping from the rail wall surface of the second slide rail 14, it is formed integrally when the second slide rail 14 is formed, so that the inclination preventing means 70 can be easily formed. In addition, when the protrusion 72 is formed by punching, the protrusion 72 is elastically engaged with the opposing engagement wall surface 74 and smoothly performs the drawing operation of the drawer body 3 without resistance. Can do. In particular, when the projecting protrusion 72 has the inclined engagement surface 72E, the protrusion 72 can be smoothly engaged with the opposing engagement wall surface 74, and the smoothness of the drawing operation of the drawer body 3 is further improved. be able to.

  According to the present invention, in the drawer slider having a locking means for releasing the lock by pushing the drawer body in the pulling direction once, the drawer body is not shifted from the center of the drawer body to the left or right to open the drawer body. Even if it is pushed in at a different position, the locks of the sliders on both sides can be reliably released and the drawer body can be effectively pulled out, which has high industrial applicability.
