Abstract

A drawer slider in which, in normal use, a drawer body is unlocked when it is pushed in the direction of closing the drawer body, but, even if the drawer body is pulled out without pushing it in the closing direction, a lock is not broken. A drawer slider has a forward end (14E)(metal magnetic body (68B)) of a slide rail (14) on the drawer body side and also has a magnet (68M) attached to a separation member (62) removably joined to a slide member (40) for locking moving along with the slide rail (14). The slide rail (14) and the slide member (40) are joined together via the separation member (62). When an attempt is made to forcibly open the drawer body without releasing the lock, the slide rail (14) is separated from the magnet (68B) to enable the drawer body to be opened without breaking the lock.

Description

Specification

Drawer slider

Technical field

[0001] The present invention provides a force that locks a drawer that is slidably supported in a housing via a slide rail and opens and closes in a closed state. When the drawer is opened, the drawer is pushed in the closing direction to release the lock. This relates to the improvement of the drawer slider.

Background art

[0002] This type of drawer slider is attached between a casing and a drawer main body that is housed in the casing so as to be freely retractable. The drawer main body is pulled into the casing, or the drawer main body is pulled into the casing. It can be pulled out smoothly, and has a function of locking the drawer body to the housing while the drawer body is pulled into the housing.

[0003] This type of drawer slider includes a first slide rail to be attached to the inner wall surface of the casing, and a drawer that slidably engages with the first slide rail and moves freely in and out of the casing. A second slide rail to be attached to the main body, and a locking means for locking the first and second slide rails together when the drawer main body is pulled into the housing.

[0004] The locking means is attached to the second slide rail, and a slide piece with a guide groove that is detachably coupled to the distal end of the first slide rail and moves together with the drawer body when the drawer body is retracted. The lock pin that engages the guide groove of the slide piece is a lock member in the form of a lever that displaces in the width direction. The guide groove engages with the lock pin of the mouth member when the drawer body is confined. When pulling out the lock surface that locks the lock member and the retracting side guide surface that guides the lock pin toward the lock surface when the drawer body is pulled in, pull out the drawer body once in the pull-out direction when pulling out the body. The slide pin has a forward guide surface that guides it toward the opening while removing the lock pin from the lock surface of the lock member, and the slide piece is a first slider when the drawer body is pulled out. Adapted to be released from the tip of Doreru! /, Ru (see Patent Document 1).

[0005] A drawer cabinet using this drawer slider is used to pull the drawer body into the housing. When the first slide rail force s is connected to the slide piece and this slide piece is pushed in, the lock pin of the lock member is relatively engaged in the guide groove, and the pull-in of the drawer body is released. Since the drawer body moves slightly in the opening direction by the spring, the lock pin of the lock member engages with the lock surface of the guide groove to lock the drawer body in the housing.

[0006] Next, when pulling out the drawer body, the drawer body is piled on a spring and pushed in the direction of pulling once. In this way, the slide piece engages with the forward guide surface of the guide groove. Since the pin is engaged, the lever-shaped lock member is displaced laterally (swings) so as to be disengaged from the lock surface of the guide groove of the slide piece, and thus the lock pin of the lock member is Since it is guided to the opening of the guide groove of the slide piece, the drawer body is pulled out together with this slide piece, and when it is pulled out beyond the predetermined position, the connection between the first slide rail and the slide piece is released and the drawer body is Pulled out with the first slide rail.

[0007] In this way, the drawer slider locks the drawer body in the retracted position. Therefore, when the drawer body does not open unintentionally, and when it is desired to open the drawer body, the drawer body is piled up with a spring and retracted once. You can easily release the lock by pushing in the direction.

However, when the user opens the drawer cabinet, if the drawer body is forcibly pulled in the pull-out direction without first pushing the drawer body in the pull-out direction, the slide piece and the lock pin of the lock member are locked. Since the drawer body is opened while maintaining the position, a large force may be applied between the slide piece and the lock pin to destroy the locking means. If the locking means breaks, the drawer will be locked thereafter. There was a drawback that could not be.

Problems to be solved by the invention

[0010] The problem to be solved by the present invention is to provide a drawer slider that can be pulled out without breaking the locking means even if the drawer body is forcibly opened without being pushed in in the pulling direction. There is to do.

Means for solving the problem

[0011] The problem solving means of the present invention is the first slide rail to be attached to the inner wall surface of the housing. And the second slide rail to be attached to the drawer main body that is slidably engaged with the first slide rail and moves freely in and out of the housing. A locking means is provided for locking the first and second slide rails to each other when the drawer body is pulled into the housing. When the drawer body is pulled out, the drawer body is pushed in the pulling direction to pull the first and second slide rails. In the drawer slider that releases the lock between the two slide rails, the first and second slide rails are coupled with a coupling force weaker than the locking force of the locking means, and the drawer body is pushed in in the closing direction. The drawer further comprises releasable coupling means for separating the first slide rail and the second slide rail when the drawer body is opened without performing the operation. To provide a slider.

[0012] In the problem solving means of the present invention, the lock means is attached to one of the first and second slide rails, and the releasable coupling means is the lock means and the other of the first and second slide rails. In particular, a separation piece that is slidably held on the frame of the locking means and is detachably coupled to the locking means and the tip of the other slide rail It's better to have it in between.

[0013] In a specific form of the present invention, the lock means is slidably held on a frame attached to one of the first and second slide rails, and the tip of the other slide rail. A slide piece with a guide groove that is detachably coupled to a portion, and a lock member that is swingably supported by this frame and that engages with the guide groove of the slide piece and displaces in the width direction. The lock member moves relatively within the guide groove of the slide piece as the drawer body moves, and the guide groove of the slide piece is locked by the lock pin of the lock member engaging when the drawer body is confined. After pulling the lock pin to the lock surface when the lock surface that locks the member and the drawer main body is retracted, the drawer main body is pulled out when the withdrawal side guide surface and the drawer main body are pulled out. The slide piece has a forward-side guide surface that guides it to the opening so that the lock pin is removed from the lock surface and is moved away from the lock surface, and the slide piece of the other slide rail is pulled out when the drawer body is pulled out. The slide piece with the guide groove is slidably held on the frame, the lock member is supported by the frame so as to be displaceable in the lateral direction, and the releasable coupling means is configured to be released from the front end. It shall be provided between the frame and the tip of the other slide rail That's the power S.

[0014] In this case, the separation piece that is detachably coupled to the slide piece is slidably held on the frame of the lock means, and the releasable coupling means is formed between the separation piece and the tip of the other slide rail. It may be provided between them.

[0015] In the problem solving means of the present invention, the releasable coupling means comprises two magnetic coupling members that are magnetically coupled to each other, and performs a pushing operation of the bow I projecting body in the bow I penetration direction. Without opening the drawer body, it is possible to force these two magnetic coupling members to pile up and separate from the magnetic attractive force. In this case, the two magnetic coupling members may be a magnet and a metal magnetic material, or both may be magnets.

[0016] Further, in place of the above, the releasable coupling means is composed of two sandwiching members that are mutually inertially engaged, and the drawer main body is not pushed in in the pulling direction of the drawer body. Opening may cause these two mating members to separate against the elasticity of the mating.

[0017] Of the members, the male and female mating of the releasable coupling means! /, The male mating! /, The member is a horizontal protrusion, and the female mating member is the horizontal projecting piece. The male side mating member may be a pair of locking pins, and the female side mating member may be engaged with this pair of locking pins in inertia. It may be a locking piece having an engaging groove.

The invention's effect

[0018] According to the present invention, as described above, the first and second slide rails are coupled with each other rather than the locking force of the locking means, and the drawer main body is not pushed in in the pull-in direction. Opening includes a releasable coupling means that separates the first and second slide rails, so that the user pulls the drawer body in the pull-out direction without pushing the drawer body once in the pull-in direction. Even if this happens, the first and second slide rails are automatically separated by this releasable coupling means, so that a large force is applied to the locking means even if the locking means remains locked. Therefore, there is an advantage that the drawer body can be locked even after the locking means has been destroyed.

The drawer slider S is shown in FIGS. 1 to 4 and FIGS. As shown in Fig. 9, the first slide rail 12 to be attached to the inner wall surfaces on both sides of the housing 2 and the slide body 12 slidably engaged with the first slide rail 12 and attached to both side surfaces of the drawer body 3 The second slide rail 14 to be A lock means 20 is provided for locking the first and second slide rails 12 and 14 to each other when retracted.

[0021] In the illustrated example, the first slide rail 12 is an outer slide rail, the second slide rail 14 is an inner slide rail, a force S, and the first slide rail 12 is an inner side and a second slide rail. 14 may be outside. Further, in the illustrated example, the force in which the intermediate slide rail 16 is provided between the first and second slide rails 12 and 14 may be omitted. In FIGS. 5 to 9, reference numerals 12H and 14H are holes for mounting bolts used to mount the first and second slide rails 12 and 14 to the housing 2 and the drawer body 3, respectively.

[0022] Hereinafter, the force for describing the one-side drawer slider S in detail. The other-side drawer slider S is also configured symmetrically with the same force as the one side.

[0023] The locking means 20 is a metal or rigid plastic frame 30 fixedly attached to the back end of the first slide rail 12, and is slidably held on the frame 30, which will be described later. The slide piece 40 with the guide groove that moves to the back together with the drawer main body 3 when the drawer main body 3 is retracted and the rear end of the frame 30 It comprises a lever-like lock member 50 having a lock pin 54 that is supported by a swing pin 52 so as to be swingable and engages with a guide groove 46 of the slide piece 40. In the example shown in the figure, the lock member 50 displaces the lock pin 54 in the width direction of the frame 30 while the lock pin 54 is displaced in the lateral direction by the swinging of the lock member 50. If it is possible, it does not have to be a lever.

As shown in FIGS. 14 to 17, the frame 30 has a substantially T-shaped configuration in which a horizontal piece 34 is integrally provided at one end of a frame body 32, and the horizontal piece 34 is a first slide. The frame body 32 has a bottom locking hole 32H that is fitted in the opening at the back end of the rail 12 (see FIGS. 5 to 9), and the first slide rail 12 has a bottom locking hole 32H. The claw piece 12P raised and raised at the bottom of the frame is inertially locked (see FIGS. 10 to 13), whereby the frame 30 is fixed to the first slide rail 12.

As shown in FIG. 18, the slide piece 40 with guide grooves has two pairs of holding pins 42F and 42R on the front and rear sides of both sides, and these holding pins 42F and 42R are connected to the frame body 32 of the frame 30. Both The frame 30 is held in the frame 30 by being slidably fitted in a holding groove 32G provided in the side wall in the longitudinal direction of the frame body 32. The holding groove 32G is inclined horizontally as indicated by reference numeral 32GI in the middle portion of the frame main body 32, while the force S extends horizontally as indicated by reference numeral 32GH on the side piece 34 side.

[0026] Accordingly, the slide piece 40 is directed to the back end of the first slide rail 12 (direction of the drawer body).

3) and the front and rear holding pins 42F and 42R are in the horizontal part 32GH of the holding groove 32G, the horizontal state is maintained (see Fig. 10 and Fig. 11). Moves in the opposite direction (the direction in which the drawer body 3 is pulled out) and the front holding pin 42F enters the inclined portion 32GI of the holding groove 32G, the front side is inclined downwards and / or maintains the inclined state (Fig. 1 2 And Figure 13).

[0027] The slide piece 40 has front and rear engaging pieces 44F and 44R projecting from the upper surface thereof, and these engaging pieces 44F and 44R are separation pieces to be connected to the second slide rail 14 to be described later. It has a function of moving the slide piece 40 forward and backward together with the second slide rail 14 by sandwiching.

As shown in FIG. 19, the guide groove 46 of the slide piece 40 has a wide opening 460 at the rear end, and further, when the drawer body 3 is retracted, it engages with the lock pin 54 of the lock member 50. The lock surface 46L that continues to the opening 460 and the lock pin 54 of the lock member 50 are guided so that the lock pin 54 is guided to the lock surface 46L when the drawer body 3 is pulled in to lock the lock member 50. Pull-out retracting side guide surface 46R that retreats and the drawer pin 3 of the lock member 50 when the drawer body 3 is opened are retracted while narrowing so that the lock pin 54 is disengaged from the lock surface 46L, and then the drawer is advanced and guided to the opening 460. And a forward guide surface 46F. In FIG. 19, 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 comes into contact with the lock pins 54. The symbols “a, b, c” are added in the order of the operations. The guide surfaces 46Rd and 46Fb are longer than the position where the drawer body 3 is kept closed so that the second slide rail 14, that is, the lock pin 54 can be displaced slightly in the closing direction. It is formed by extending.

[0029] As can be seen from FIGS. 10 to 13, the spring 48 is provided between the slide piece 40 and the frame 30 and normally moves the slide piece 40 in the drawing direction (opening direction) of the drawer body 3. Energized. The flange 48K at one end of this spring 48 is the front end spring hook pin 40P of the slide piece 40. The shoulder 48S at the other end is engaged with a notch hole 30N provided on the inner side of the front end of the frame 30 and is latched!

[0030] To close the drawer cabinet 1, the drawer body 3 is pulled in and the second slide rail 14 is slid so as to be housed in the first slide rail 12, and the front end of the second slide rail 12 is inserted. When the slide piece 40 is moved to the back end side of the first slide rail 12 through the section, the lock pin 54 of the lock member 50 is retracted from the opening 460 of the guide groove 46 of the slide piece 40. Guide surfaces 46Ra, 46Rb, The force that engages with the extension part of the retracting side guide surface 46Rd while being narrowed by the swing of the lock arm 50 through 46Rc The direction in which the slide piece 40 opens the drawer body 3 by the spring 48 when the hand is released from the drawer body 3 Therefore, the lock pin 54 of the lock member 50 is engaged with the lock surface 46L of the guide groove 46 of the slide piece 40, and the slide piece 40, that is, the second slide rail 14 is returned to the direction in which the drawer body 3 is opened. No (See Fig. 5, Fig. 10 and Fig. 14).

[0031] Next, in order to open the drawer cabinet 1, the drawer body 3 is pushed in the direction of being retracted (closed) against the spring 48, and the slide piece 40 is moved through the second slide rail 14 to the first position. When the slide pin 12 is displaced to the rear end side, the lock pin 54 of the lock member 50 is extended by the forward guide surface 46Fa while being shifted from the lock surface 46L of the guide groove 46 of the slide piece 40 by the forward guide surface 46Fa. Then, when the drawer body 3 is pulled out, the slide piece 40 is moved in the pull-out direction via the second slide rail 14. For this reason, the lock pin 54 of the mouthpiece member 50 has the guide groove 46. It escapes from the opening 460 of the guide groove 46 while being further reduced by the forward guide surface 46Fc. Thus, when the slide piece 40 moves forward along the holding groove 32G of the frame 30, the holding pin 42F in front of the slide piece 40 is inclined forward downward along the front inclined surface 32GI of the holding groove 32G. Therefore, the second slide rail 14 is released through the coupling means described later, and the second slide rail 14 moves forward along the first slide rail 12 so that the drawer body 3 can be pulled out and opened.

[0032] The drawer slider S of the present invention couples the first slide rail 12 and the second slide rail 14 with a coupling force weaker than the locking force of the locking means 20, and closes the drawer body 3 in the closing direction (drawing). The releasable coupling means 60 is provided to forcibly separate the first slide rail 12 and the second slide rail 14 when the drawer body 3 is opened without pushing in the direction of The In the illustrated form, the locking means 20 is attached to the first slide rail 12, and the releasable coupling means 60 is connected between the locking means 20 on the first slide rail 12 and the second slide rail 14. The force locking means 20 provided between them is mounted on the second slide rail 14 and the releasable coupling means 60 is connected to the locking means 20 on the second slide rail 14 and the first slide rail 12. It may be provided between.

[0033] In the illustrated embodiment, the releasable coupling means 60 includes a separation piece 62 and a second slide rail 14 that are slidably held on the frame 30 so as to be detachably coupled to the slide piece 40. It is provided between the tip portion 14E.

[0034] In one form, the releasable coupling means 60 includes two magnetic coupling members 66 that are respectively attached to the separation piece 62 and the tip end portion 14E of the second slide rail 14 and magnetically coupled to each other. When the drawer body 3 is opened without pushing the drawer body 3 in the closing direction, the two magnetic coupling members 66, 68 are separated from each other by staking them into the magnetic attraction force. ing.

[0035] As shown in FIGS. 14, 18, and 20, the separation piece 62 has an inverted U-shaped configuration having holding rails 62L that engage with sliding grooves 30S on both sides of the frame 30. These holding rails 62L are slidably held by the frame 30, and the holding pieces 62L of the slide piece 40 can be retracted so that the separating piece 62 can be retracted together with the slide piece 40 in the drawing direction of the drawer body 3. The 32G horizontal part can also enter 32GH. As shown in FIG. 18, the front end of the sliding groove 3 OS is closed by a front end stop wall indicated by reference numeral 30SW. Therefore, the separation piece 62 has its holding rail 62L engaged with the closing wall 30SW. Then, you can't move forward ahead of it.

[0036] Further, the separating piece 62 is a holding portion 64 formed so as to be held between the front and rear engaging pieces 44F, 44R of the slide piece 40 that is in the forward movement position and inclined forward. The holding portion 64 can be formed by providing a hole 62H into which the front engagement piece 44F of the slide piece 40 is engaged in the rear portion of the separation piece 62.

[0037] In the illustrated form, the two magnetic coupling members 66 and 68 each include a magnet 66M and a metal magnetic body 68B, and the magnet 66M is fixed to the upper surface of the front end of the separation piece 62, and the metal magnetic body 68B is The second slide rail 14 itself consists of. Next, the usage state of the drawer slider S according to the embodiment of the present invention will be described as follows.

(A) Drawer main body of drawer cabinet 1 320 retracted and closed state = received state (see Fig. 1, Fig. 5, Fig. 10 and Fig. 14)

In this state, the second slide rail 14 is in the contracted state accommodated in the first slide rail 12, and the front end 14E of the second slide rail 14 (the portion that becomes the metal magnetic body 68B) is on the frame 30. In the slide piece 40, the lock pin 54 of the lock member 50 is engaged with the lock surface 46L of the guide groove 46 as shown in FIG. 19 (C) [a]. It is in the reverse lock position to be stopped.

[0039] (B) Starting state in which the drawer body 3 is to be pulled out = push-in state (see FIGS. 2, 6, 11, and 15)

This state is a trigger state in which the locking means 20 is to be released in order to pull out (open) the drawer body 3. When the drawer body 3 is pushed in the direction opposite to the opening direction, the lock pin 54 is swung by the backward movement of the slide piece 40 and the lock pin 54 is moved along the backward side guide surface 46Fa to the position “b” in FIG. Since the slide piece 40 moves backward against the spring 48 while the width is reduced, the lock member 50 is released from the locked state with respect to the slide piece 40.

[0040] (C) The initial state of the drawer body 3 (see FIGS. 3, 7, 12, and 16)

When the drawer body 3 is pulled out with the lock released as described above, the slide piece 40 moves forward away from the hook member 50, and accordingly, the lock pin 54 of the lock member 50 is moved forward. While guiding through 46Fb and 46Fc to the opening 460 of the guide groove 46, the lock member 50 tries to separate.

[0041] (D) Drawer body 3 is in a fully drawn state (see FIG. 4, FIG. 8, FIG. 13 and FIG. 17)

In this way, when the drawer body 3 is pulled out (opened), the second slide rail 14 moves forward together with the separation piece 62 and the slide piece 40. First, the front holding pin 42F of the slide piece 40 holds the frame 30. When the front engaging piece 44F of the slide piece 40 descends by entering the downward inclined portion 32GI of the groove 32G, the separating piece 62 is disengaged from the engaging piece 44F, so that the separating piece 62 remains in the first position, leaving the slide piece 40. The two slide rails 14 move forward. In this way, the separation piece 62 When the most advanced position of the ram 30 is reached, the holding rail 62L of the separation piece 62 is locked to the tip retaining wall 30SW of the holding groove 30S of the frame 30 and cannot move further, so the second slide rail 14 Since the metal magnetic body 68B, which is the tip 14E of the magnet, is piled and separated by the magnet 66M force on the separation piece 62 in the magnetic attraction force, the second slide rail 14 moves forward and leaves with the separation piece 62 left in the frame 30. Pull out body 3.

[0042] (E) The drawer body 3 is forcibly pulled out without pushing the drawer body 3 in the drawing direction (see FIG. 9).

As shown in FIGS. 5 and 10, when the drawer body 3 is closed, the separation piece 62 magnetically coupled to the second slide rail 14 is in the retracted position together with the slide piece 40, and the slide piece 40 Since the lock pin 54 on the lock member 50 is engaged with the lock surface 46L of the guide groove 46, the separation piece 62 is locked in this retracted position, and the separation piece 62 cannot advance. Therefore, the second slide rail 14 cannot move forward even if it is pulled out before it is pushed in the closing direction, but if the drawer body 3 is forcibly pulled out, the releasable coupling means 60 Since the coupling between the magnet 66M on the separation piece 62 side and the metal magnetic body 68B, which is the tip 14E of the second slide rail 14 is piled up and released by the magnetic attractive force, the second slide rail 14 The separation piece 62 can be moved forward together with the slide piece 40 while remaining in the lock retracted position, and the drawer body 3 can be pulled out.
