A mechanism unit incorporating a soft close mechanism and a push-open mechanism, in which a soft-close mechanism or a push-open mechanism is operated, and a base that is long in the direction of movement of the drawer, and is slidable in the direction of movement of the drawer by the base The slider is supported by the first horizontal support shaft provided on the slider and orthogonal to the moving direction of the drawer, which is located on the side closer to the drive pin of the slider with the drawer opened. The first driven part is supported on the free end part on the side close to the driving pin. And a second driven surface is formed at the free end on the side far from the drive pin, and a latching body horizontally provided between the first horizontal support shaft and the first driven surface is formed. The direction of movement of the drawer, which is guided by a guide portion that is long in the direction of movement of the drawer formed on the base body, and that the latching body can move from an end portion of the guide portion to a latching portion that bends. A first seesaw-like rocking member that is long, and in a state in which the drawer is opened, in the moving direction of the drawer provided on the slider, which is located farther from the drive pin than the first horizontal support shaft. A driven surface on which a drive pin is pressed when the soft closing mechanism is operated and when the push open mechanism is operated, and the soft closing mechanism is supported by an orthogonal second horizontal support shaft Is activated A hook-shaped engagement portion with which the drive pin engages in a state where the drive pin is engaged, and a drive surface that presses the second driven surface of the first swing member when the soft-close mechanism is operated. A second elastic member, a first elastic member that applies a restoring force to the slider in a direction in which the drive pin is retracted when the soft-close mechanism is operated, and the first elastic member.

The drawer can be automatically opened by the elastic energy of the second elastic member released when switching to the small second swing position.
In addition, when the soft close mechanism is operated, the second swing member is operated by the drive pin, and the hook-shaped second swing member is switched from the second swing position to the first swing position by the switching means. At this time, the drive pin engages with the hook-shaped engagement portion of the second swing member, and the drive surface of the second swing member presses the second driven surface of the seesaw-shaped first swing member. Since the first rocking member is swung from the latching member to disengage from the latching portion, the drawer can be slowly and automatically closed by the restoring force of the first elastic member and the braking force of the damper.
As described above, the two positions where the bowl-shaped second swinging member swings are alternately switched by the switching means, and the drive pin presses the driven surface of the second swinging member, so that the soft closing mechanism or When the push-open mechanism is activated and the soft-close mechanism is activated, the seesaw-shaped first rocking member is linked with the rocking of the seesaw-shaped first rocking member in conjunction with the rocking of the second rocking member. Since the latching body of the moving member is configured to be removed from the latching portion, a mechanism unit incorporating a soft close mechanism and a push-open mechanism can be realized with a relatively simple and compact configuration.

Here, the switching means is connected to the end different from the bowl-shaped tip of the second swinging member so as to be swingable about a horizontal axis perpendicular to the moving direction of the drawer, and (2) a latch extending in the opposite direction to the elastic member, and a guide groove formed in the slider for guiding the free end of the latch to rotate in one direction. It is preferable that a first latching portion corresponding to the first swinging position and a second latching portion corresponding to the second swinging position for hooking the free end portion of the latching device are provided on the way. (Claim 2).
According to such a configuration, the switching means for alternately switching the two positions where the second swinging member swings includes the latch connected to the second swing member and the free end of the latch. Since it is realized by a simple configuration comprising a guide groove provided with a first latching portion and a second latching portion by guiding and circulating in one direction, it is possible to reduce costs and ensure operation. it can.

  Moreover, the mechanism unit incorporating the soft close mechanism and the push open mechanism according to the present invention is attached to one of the main body and the drawer of the furniture and the drive pin attached to the other of the main body and the drawer in order to solve the problem. Is a mechanism unit incorporating a soft close mechanism and a push open mechanism, which is operated by a soft close mechanism or a push open mechanism, and a base that is long in the movement direction of the drawer, and a movement direction of the drawer by the base A first slider that is slidably supported, and is perpendicular to the moving direction of the drawer provided on the first slider, which is located on the side closer to the drive pin of the first slider, with the drawer open. The intermediate portion in the longitudinal direction is supported by the first horizontal support shaft, and on the side close to the drive pin A driven surface is formed at the end portion, and a rotary connecting portion is formed at the free end portion on the side far from the drive pin, and is provided laterally between the first horizontal support shaft and the driven surface. One latching body is guided by a guide portion that is formed in the base and is long in the moving direction of the drawer, and the first latching body may move from an end portion of the guide portion to a latching portion that bends. A first seesaw-like swinging member that is long in the direction of movement of the drawer, and the first slider that is located farther from the drive pin than the first horizontal support shaft with the drawer open. A hook-shaped intermediate portion is supported by a second horizontal support shaft that is perpendicular to the moving direction of the drawer, and the drive pin is pressed when the soft-close mechanism and the push-open mechanism are operated. Driven surface, and A hook-like second swinging member formed with a hook-like engaging portion that engages with the drive pin in a state in which the soft-close mechanism is activated, the first horizontal support shaft, and the second horizontal support shaft; A middle portion in the longitudinal direction is supported by a third horizontal support shaft that is provided in the first slider and is perpendicular to the moving direction of the drawer, and is connected to the rotation connecting portion of the first swing member. The moving direction of the drawer in which the rotation connecting portion is formed at one end, and the driven surface driven by the driving surface of the second swing member is formed at the other end when the soft closing mechanism is operated. A second see-saw-like connecting member and a second latch horizontally supported at an end different from the bowl-shaped tip of the second swinging member and supported by the first slider so as to be slidable in the moving direction of the drawer. A long guide section in the direction of movement of the drawer that guides the body A hooking portion that is formed and bent from an end of the guide portion to hook the second hooking body is formed, and a pressing surface that presses the drive pin in a state where the push-open mechanism is operated The formed second slider, the first elastic member that applies a restoring force to the first slider in the pulling direction when the soft closing mechanism is operated, and the first elastic member is urged by the first elastic member A damper that dissipates the kinetic energy of the first slider and brakes the first slider; and when the push-open mechanism is actuated on the second swinging member via the second slider. A second elastic member having a restoring force smaller than that of the first elastic member, wherein a restoring force is applied in a direction in which the drive pin is pushed out, and a large amount of elastic deformation of the second elastic member; A first slide position of the second slider where the second hooking body of the second swinging member is hooked on a hooking portion of the second slider, and an amount of elastic deformation of the second elastic member is small. And a switching means for alternately switching and holding the second sliding position of the second slider guided by the guide portion of the second slider. (Claim 3).

According to such a configuration, when the drawer is fully closed, the second slider is in a first slide position where the elastic deformation amount of the second elastic member is large by the switching means, and the second swinging member The drive pin is engaged with the hook-like engagement portion of the second swing member in a state where the second engagement body is engaged with the engagement portion of the second slider.
When the drawer is pushed in this state, the driven surface of the second swing member is pressed by the drive pin, and the second latching body of the second swing member is latched on the latching portion. When the second slider is pushed and moved, and the switching means switches the second slider to the second slide position where the elastic deformation amount of the second elastic member is small, the restoring force of the second elastic member is The drive pin acts on the drive pin from the driven surface of the second swing member and the pressing surface of the second slider to press the drive pin in the direction to open the drawer, and the second hook of the second swing member. Since the stopper moves from the latching portion of the second slider to the guide portion, the second swinging member swings and the drive pin is disengaged from the hook-like engagement portion, so that the drawer is automatically opened. be able to.
Further, in accordance with the operation of opening the drawer, the drive pin moves while pressing the driven surface of the first swing member, the first elastic member is elastically deformed, and the first swing member is The first latching body moves to the latching portion of the base while being guided by the guide portion of the base, and the first latching body is latched on the latching portion. Since the oscillating member is oscillating, the drive pin can move away from the driven surface, so that the drawer can be fully opened.
Further, when the driven surface of the second swing member is pressed by the drive pin and the second swing member swings with the operation of closing the drawer, the drive pin is moved to the second swing member. Since the driving surface of the second rocking member pushes the driven surface of the coupling member, the coupling member rocks, and accordingly, the first rocking member Swing about the first horizontal support shaft, the first hooking body is disengaged from the hooking portion, and the restoring force of the first elastic member and the braking force of the damper are engaged with the hook-like engaging portion. The drawer slowly and automatically closes in order to be transmitted to the driving pin.

That is, the first sliding position of the second slider in which the second latching member of the second swinging member is latched by the latching portion of the second slider, and the second elastic member has a large elastic deformation amount by the switching means. The second elastic member has a small elastic deformation amount, and the second sliding position of the second slider in which the second latching member of the second swinging member is guided by the guide portion of the second slider is alternately switched and held. When operating the push-open mechanism, the second rocking member is operated by the drive pin, and the second elastic member has a small elastic deformation amount from the first slide position where the second elastic member has a large elastic deformation amount. The drawer can be automatically opened by the elastic energy of the second elastic member released when switching to the two-sliding position.
In addition, when the soft close mechanism is operated, the second swing member is operated when the second swing member is operated by the drive pin and the second slider is switched from the second slide position to the first slide position by the switching unit. The driving pin engages with the hook-shaped engaging portion of the member, and the driving surface of the second swinging member pushes the driven surface of the connecting member to swing the first swinging member via the connecting member. Since the latching body is detached from the latching portion, the drawer can be closed slowly and automatically by the restoring force of the first elastic member and the braking force of the damper.
As described above, the two slide positions of the second slider are alternately switched by the switching means, and the driven surface of the second swinging member in which the second latching body is engaged with the guide portion and the latching portion of the second slider. When the drive pin is pressed, the soft closing mechanism or the push-open mechanism is activated. When the soft closing mechanism is activated, the seesaw-shaped connecting member and the seesaw-shaped first member Since the first hooking member of the seesaw-shaped first rocking member is detached from the hooking portion so that the rocking of the rocking member is interlocked, the software is relatively simple and compact. A mechanism unit incorporating a close mechanism and a push-open mechanism can be realized.
In addition, in comparison with the first aspect of the invention, a first slider and a second swing member are connected by a connecting member, and a second slider is provided that is slidably supported by the first slider. Since the restoring force of the second elastic member is applied to the drive pin by the pressing surface of the second slider, the stroke that is automatically opened by the push-open mechanism can be increased, so that the hand can easily enter the drawer. Therefore, operability can be improved.

Here, the switching means is connected to the second slider so as to be swingable about a horizontal axis orthogonal to the moving direction of the drawer, and extends in a direction opposite to the second elastic member; A guide groove that guides the free end portion of the tool, and the guide groove is connected to a circumferential groove portion that circulates the free end portion of the latching tool in one direction, and an end portion of the circumferential groove portion in the moving direction of the drawer. The reciprocating groove portion extends in the moving direction of the drawer and reciprocates the free end portion. The middle of the circumferential groove portion is a first hooking portion corresponding to the first slide position, and the end portion of the reciprocating groove portion is the end portion. Preferably, the second latching portion corresponds to the second slide position.
According to such a configuration, the switching means for alternately switching the two slide positions of the second slider that are separated from each other so as to expand the stroke of the push-open mechanism includes a latch connected to the second slider, Since it is realized by a simple configuration comprising a guide groove composed of a circumferential groove portion provided with a first hook portion and a reciprocating groove portion provided with a second hook portion, which guides the free end portion of the hook device. Cost reduction and reliable operation can be achieved.

  As described above, according to the mechanism unit incorporating the soft close mechanism and the push-open mechanism according to the present invention, the two positions where the bowl-shaped second swing member swings (two slide positions of the second slider). Are alternately switched by the switching means, and when the drive pin presses the driven surface of the second swing member, the soft close mechanism or the push-open mechanism is operated. The swinging member (first latching member) of the seesaw-shaped first swinging member is detached from the latching part by interlocking the swinging of the seesaw-shaped first swinging member with the swinging of the moving member. Therefore, it is possible to realize a mechanism unit incorporating a soft close mechanism and a push-open mechanism with a relatively simple and compact structure, thereby reducing the manufacturing cost. It is, a marked effect of being able to use readily attached to the body or withdrawal of existing furniture or new furniture.

A step 10C that falls between the planes g and h in the middle of the path M3, and a step 10D that falls between the planes h and a in the middle of the path M4. A portion 10A is formed, the planes b and d are connected by a slope c, and the planes e and g are connected by a slope f.

Therefore, the free end portion 9B of the latching pin 9 drops the stepped portions in order while reducing the stepped amount of the stepped portions 10A, 10B, 10C, and 10D to ensure smoothness and reliability of operation. However, it goes around in one direction of the paths M1, M2, M3, and M4 along the guide groove 10 without returning in the reverse direction.
Further, in the middle of the circulation path of the guide groove 10, the first swing position of the second swing member 4 that latches the free end portion 9 </ b> B of the latch pin 9 and has a large elastic deformation amount of the second elastic member 8. And the second hooking portion P2 corresponding to the second swinging position of the second swinging member 4 where the elastic deformation amount of the second elastic member 8 is small. The first swing position and the second swing position can be alternately switched by the switching means S (the latch pin 9 and the guide groove 10 which are latches).

Next, operations of the soft close mechanism A and the push open mechanism B of the mechanism unit 1 will be described.
As shown in FIG. 4, the slider 2, the first elastic members 5, 5 and the damper 6, the first swing member 3, the sliding grooves 13 </ b> A and 13 </ b> B that are guide portions, and the engaging grooves 14 </ b> A and 14 </ b> B that are engaging portions. In addition, the second swing member 4 constitutes the soft close mechanism A.
Further, the slider 2, the second elastic member 8, the latching pin (holding tool) 9, which is the switching means S, the guide groove 10, and the second swing member 4 constitute a push-open mechanism B.

In a state where the drawer D shown in FIG. 4 is fully closed (see also FIG. 2), the switching means S causes the free end portion 9B of the latch pin 9 to be the first latch portion P1 of the guide groove 10 (see FIG. 5). ) Is held.
In the state of FIG. 6A in which the front surface of the drawer D is pushed to operate the push-open mechanism B from this state, the driven surface 4F of the second rocking member 4 is pushed by the driving pin K and the second rocking member 4 is pushed. The moving member 4 swings backward around the second horizontal support shaft 2B, and the switching means S causes the free end portion 9B of the latching pin 9 to be hooked on the second latching portion P2 (see FIG. 5) of the guide groove 10. When switching to the stopped state of FIG. 6B, the second swinging member 4 swings forward around the second horizontal support shaft 2B.

  Therefore, from the 1st rocking | fluctuation position of the 2nd rocking | fluctuation member 4 with the large elastic deformation amount of the 2nd elastic member 8 in which the free end part 9B of the latching pin 9 was located in the 1st hooking part P1, the latching pin 9 When the free end portion 9B of the second elastic member 8 is switched to the second swing position of the second swing member 4 where the elastic deformation amount of the second elastic member 8 located at the second hooking portion P2 is small, the elasticity of the second elastic member 8 is changed. The energy is released, and the restoring force of the second elastic member 8 acts on the drive pin K from the driven surface 4F of the second swing member 4 to push the drive pin K forward (in the direction of opening the drawer D). Since the second swing member 4 swings and the drive pin K is disengaged from the hook-shaped engagement portion 4E, the drawer D is automatically opened.

In the state of FIG. 6B, the drawer D is open in the range up to the position where the drive pin K contacts the first driven surface 3D of the first swing member 3, so that the drawer D is as shown in FIG. Even if there is no handle or handle on the front surface, the drawer D can be opened with the upper edge of the front plate F of the drawer D, for example.
With the operation of opening the drawer D, as shown in FIG. 6C, the drive pin K moves forward while pressing the first driven surface 3 </ b> D of the first swing member 3, and the first elastic member 5. , 5 are elastically deformed, and the latching bodies 3B, 3C of the first swing member 3 are moved to the latching grooves 14A, 14B while being guided by the sliding grooves 13A, 13B of the base body 1A and the lid body 1B. It will be in the state which the latching bodies 3B and 3C latched in the latching grooves 14A and 14B.

In this state, the first rocking member 3 is rocked and latched, and since the first driven surface 3D of the first rocking member 3 is separated from the drive pin K, the first elastic member is attached to the drawer D. The drawer D (driving pin K) can be moved forward as shown in FIG. 7 (a) and fully opened without the restoring forces of 5 and 5 acting.
In addition, in the state of FIG.6 (c) and FIG.7 (a), the latching bodies 3B and 3C of the 1st rocking | fluctuation member 3 latched on the latching grooves 14A and 14B, and the movement of the slider 2 stopped. Since the state is maintained, elastic energy is accumulated in the first elastic members 5 and 5 constituting the soft close mechanism A.

When the drawer D is closed after the drawer D is fully opened, the driven surface 4F of the second rocking member 4 is pressed by the driving pin K as shown in FIG. The drive pin K is engaged with the hook-like engagement portion 4E of the second swing member 4, and the second swing member 4 is moved from the second swing position to the first swing position. The drive surface 4G of the second swing member 4 presses the second driven surface 3E of the first swing member 3 in the middle of switching to the first swing position, and as shown in FIG. 3 swings around the first horizontal support shaft 2A, and the latching bodies 3B and 3C are detached from the latching grooves 14A and 14B.
In this state, the restoring force of the first elastic members 5 and 5 and the braking force of the damper 6 are engaged with the hook-like engaging portion 4E of the second swinging member 4 through the slider 2 and the second swinging member 4. Therefore, the drawer D is automatically closed slowly and the drawer D shown in FIG. 4 is fully closed.

Next, a modified example of the switching means S will be described.
The main part enlarged longitudinal front view of FIG. 8 is formed with the stepped portions 10A, 10B, 10C, and 10D as shown in FIG. (See M1, M2, M3, and M4 in FIG. 8).
That is, when the free end portion 9B moves relative to the guide groove 10 from the state where the free end portion 9B of the latch pin 9 is engaged with the first engagement portion P1, the free end portion 9B is inclined. When the free end portion 9B moves forward relative to the guide groove 10 from this state, the free end portion 9B contacts the inclined wall portion 10F. After that, it moves like a path M2 so as to be in a state of being hooked on the second hooking portion P2.
Further, when the free end portion 9B of the latch pin 9 is latched to the second latch portion P2 and the free end portion 9B moves relative to the guide groove 10, the free end portion 9B is inclined. When the free end portion 9B moves relative to the guide groove 10 from this state, the free end portion 9B contacts the inclined wall portion 10H. After that, it moves like a path M4 so as to be in a state of being hooked on the first hooking portion P1.
Therefore, even in the guide groove 10 as shown in FIG. 8, the switching means S composed of the guide groove 10 and the latch pin 9 causes the second rocking member 4 having a large amount of elastic deformation to be changed. 1st swing position (the state where the free end portion 9B of the latch pin 9 is latched to the first latch portion P1) and the second swing of the second swing member 4 with a small elastic deformation amount of the second elastic member 8 The position (the state in which the free end portion 9B of the latching pin 9 is latched to the second latching portion P2) can be alternately switched and held.
Moreover, according to such a guide groove 10, since there are no step part and a slope, wear of the latch pin 9 can be suppressed.

In the above description, the mechanism units 1 and 1 are mounted on the furniture body C and the drive pins K and K are mounted on the furniture drawer D. However, FIG. As shown in the front view of (b), the mechanism units 1 and 1 may be attached to the drawer D and the drive pins K and K may be attached to the main body C, or the mechanism unit 1 may be turned upside down.
Alternatively, only one mechanism unit 1 may be mounted on the lower surface of the drawer D, and one drive pin K may be mounted on the main body C.

According to the configuration of the mechanism unit 1 incorporating the soft close mechanism and the push-open mechanism as described above, the first swing position of the second swing member 4 in which the elastic deformation amount of the second elastic member 8 is large by the switching means S. And the second swinging position of the second swinging member 4 having a small elastic deformation amount of the second elastic member 8 are alternately switched and held, and when operating the push-open mechanism B, the drive pin K 2. The elasticity of the second elastic member 8 released when the swing member 4 is operated to switch from the first swing position where the elastic deformation amount of the second elastic member 8 is large to the second swing position where the elastic deformation amount is small. The drawer D can be opened automatically by energy.
Further, when the soft closing mechanism A is operated, the second swing member 4 is operated by the drive pin K, and the hook-like second swing member 4 is moved from the second swing position to the first swing position by the switching means S. When switching to the moving position, the drive pin K engages with the hook-like engagement portion 4E of the second swing member 4, and the drive surface 4G of the second swing member 4 has a seesaw-like first swing member 3. Since the second driven surface 3E is pressed, the first rocking member 3 is swung and the latching bodies 3B, 3C are disengaged from the latching grooves 14A, 14B. Therefore, the restoring force of the first elastic members 5, 5 And the drawer D can be closed slowly and automatically by the braking force of the damper 6.

Further, the two positions at which the bowl-shaped second swinging member 4 swings are alternately switched by the switching means S, and the drive pin K presses the driven surface 4F of the second swinging member 4, thereby soft closing. When the mechanism A or the push-open mechanism B is operated and the soft close mechanism A is operated, the swing of the seesaw-shaped first swing member 3 is interlocked with the swing of the second swing member 4. Since the latching bodies 3B, 3C of the seesaw-like first swinging member 3 are configured to be removed from the latching grooves 14A, 14B, the soft close mechanism A and the push-open mechanism have a relatively simple and compact configuration. Since B can be incorporated, the manufacturing cost can be reduced, and it can be easily attached to the main body C or the drawer D of the existing furniture or new furniture.
Further, the switching means S is connected to an end different from the bowl-shaped tip of the second swing member 4 so as to be swingable about a horizontal axis perpendicular to the moving direction of the drawer D, and opposite to the second elastic member 8. And a guide groove 10 formed in the slider 2 that guides the free end portion 9B of the latch pin 9 and circulates in one direction. The first latching portion corresponding to the first swinging position of the second swinging member 4 and the second swinging member 4 that latches the free end 9B of the latching pin 9 in the middle of the circuit path. By providing the second latching portion corresponding to the second swing position, the switching means S is realized with a simple configuration, so that the cost can be reduced and the operation can be ensured.

It is slidably supported.
The seesaw-shaped first swinging member 23 is positioned on the front side (the side closer to the drive pin K) of the first slider 22 with the drawer D opened as shown in FIG. 10 (see also FIG. 17B). Since the first horizontal support shaft 21A provided in the first slider 22 in the left-right direction (perpendicular to the moving direction of the drawer D) is fitted into the shaft hole 23A, the first horizontal support shaft 22A causes the first horizontal support shaft 21A to move in the longitudinal direction. The intermediate portion is supported, and a driven surface 23D is formed at the free end portion on the front side (side closer to the drive pin K with the drawer D opened) and the rear side (from the drive pin K with the drawer D opened). A left and right connecting pin 23E, which is a rotating connecting portion, is formed at the free end portion on the far side, and a first horizontally disposed between the first horizontal support shaft 22A (shaft hole 23A) and the driven surface 23D. The sliding body 23B is a slide that is a guide portion that is formed in the base 21A and is long in the front-rear direction. While being guided by the groove 33, first Kaketometai 23B can move up lock grooves 34 a hooking portion bent from an end portion of the slide groove 33.

The hook-like second swinging member 24 is located behind the first horizontal support shaft 22A (from the drive pin K) with the drawer D opened as shown in FIG. 10 (see also FIG. 17B). Since the second horizontal support shaft 22B in the left-right direction provided on the first slider 22 located apart) is fitted into the shaft hole 24A, the bowl-shaped intermediate portion is supported by the second horizontal support shaft 22B, The driven surface 24F to which the drive pin K is pressed when the soft close mechanism is operated and the push open mechanism is operated, and the hook-like engagement portion with which the drive pin K is engaged when the soft close mechanism is operated 24E is formed.

The second slider 32 is supported by the first slider 22 so as to be slidable in the front-rear direction because the recess 32A extending in the front-rear direction engages with the protrusion 22H extending in the front-rear direction of the first slider 22, and the second slider 32 A sliding groove 32B, which is a long guide portion in the front-rear direction, is formed to guide the second hooking body 24B provided laterally at an end different from the bowl-shaped tip of the member 24. From the end of the sliding groove 32B A latching groove 32C that is a latching portion that bends and latches the second latching body 24B is formed, and a pressing surface 32F that presses the drive pin K in a state where the push-open mechanism is activated is formed.

The first elastic members 25, 25 are, for example, tension coil springs, and are provided on the front end of the first slider 22 and on the lower side of the first swinging member 23, and on the base 21A. Both ends 25A, 25B are hooked to the spring hook pins 21C, 21C at the ends.
Since the first elastic members 25 and 25 may apply a restoring force to the first slider 22 in the direction in which the drive pin K is retracted when the soft close mechanism is operated, the terminal 25A is first swung. There is no need to latch on the spring latch pin 23 </ b> C of the member 23, and both the one ends 25 </ b> A and 25 </ b> A of the first elastic members 25 and 25 may be latched on the first slider 22.
The damper 26 is, for example, an oil damper, and an E-ring 27 that is accommodated in the damper accommodating portion 21E of the base body 21A and engaged with the engaging groove 26C of the front end portion of the piston rod 26B that protrudes forward from the cylinder 26A is the first. The slider 22 engages with the engagement groove 22D at the rear end portion.
The second elastic member 28 is, for example, a tension coil spring, and has a restoring force set smaller than that of the first elastic members 25, 25. The spring latching pin 21D at the front end of the base 21A and the spring latching of the second slider 32 are provided. Both terminals 8A and 8B are hooked on the pin 32E.

As shown in FIG. 13, by inserting the connecting pin 38 inserted into the shaft hole 32 </ b> D located on the rear side of the second slider 32 into the through hole 30 </ b> A at one end of the connecting piece 30 and caulking the shaft end, The connecting piece 30 is swingably supported by the second slider 32, and the shaft end of the hooking rod 31 is inserted into the through hole 30B at the other end of the connecting piece 30 so that the shaft end is caulked. 31 is attached to the other end portion (free end portion) of the connecting piece 30, and the connecting piece 30 and the latching rod 31 constitute the latching tool 29. That is, the latching tool 29 is connected to the second slider 32 by the connecting pin 38 so as to be swingable about the left-right axis, and extends in the direction opposite to the second elastic member 28.
Further, a support shaft 36A that protrudes rightward from the middle portion of the seesaw-like shutter 36 that is long in the vertical direction is fitted into the shaft hole 22K in the rear end portion of the first slider 22, and leftward from the middle portion of the shutter 36. The projecting support shaft 36B is inserted into the shaft hole 39A of the cover 39, and the engaging convex portions 39B, 39B,... Protruding from the right surface of the cover 39 are inserted into the first slider 22 engaging concave portion 22L.

15A, the compression coil spring 37 is accommodated in the spring accommodating recess 22M at the rear end portion of the first slider 22, and the one end portion (lower end portion) of the shutter 36 is accommodated. The protruding portion 36 </ b> C at the other end (upper end) of the shutter 36 protrudes into the guide groove 40 in a state where the spring receiver 36 </ b> D is elastically biased by the compression coil spring 37.
Here, after assembling each of the above-described mechanical parts to the base 21A, the mounting screws 15, 15,... Are screwed into the screw holes 21J, 21J,. Thus, the lid 21B is attached to the base 21A, the assembly of the mechanism unit 21 incorporating the soft close mechanism and the push-open mechanism is completed, and the mounting holes 21K, 21K,... Formed in the lid 21B and the base 21A are formed. Since the attachment holes 21L, 21L,... Communicate with each other, they can be easily attached to the main body C or the drawer D of the furniture using these attachment holes.

Next, details of the switching means S will be described.
The guide groove 40 shown in the main part enlarged longitudinal front view of FIG. 15 (a) and the front view of FIG. 15 (b) guides the latching rod 31 which is the free end part of the latching tool 29. 8 and a reciprocating groove portion (paths N1, N2) extending in the front-rear direction connected to the front end portion of the circular groove portion.
Then, by the switching means S composed of the guide groove 40 and the latching tool 29, the second slider has a large elastic deformation amount of the second elastic member 28 where the latching rod 31 is in the middle of the circular groove portion. The first latching portion P1 corresponding to the first slide position 32 or the front end portion of the reciprocating groove portion corresponds to the second slide position of the second slider 32 with a small elastic deformation amount of the second elastic member 28. It switches to the 2nd latching part P2, and the latching rod 31 moves along these paths in order of M1, M2, N1, N2, M3, and M4.

Here, the protrusion 36C of the shutter 36 blocks the path M2, but when the latching rod 31 moves from the path M2 of the circumferential groove part to the path N1 of the linear groove part, the slope of the protrusion 36C is hooked. Since the shutter 36 is swung around the support shafts 36 </ b> A and 36 </ b> B against the elastic biasing force of the compression coil spring 37 by being pushed by the stop rod 31, the shutter 36 does not hinder the movement of the latch rod 31.
Further, when the latch rod 31 moves from the path N2 of the linear groove portion to the path M3 of the circular groove portion, the shutter rod 31 blocks the passage to the route M2, so that the latch rod 31 moves from the route N2. Since the movement toward the path M2 is prevented, the latching rod 31 surely moves from the path N2 to the path M3.

Next, operations of the soft close mechanism A and the push open mechanism B of the mechanism unit 1 will be described.
As shown in FIG. 14, the first slider 22, the first elastic members 25 and 25, the damper 26, the first swing member 23, the sliding groove 33 that is a guide part, and the latching groove 34 that is a latching part, connection The member 35 and the second swing member 24 constitute a soft close mechanism A.
Further, the first slider 22, the second elastic member 28, the latching tool 29 and the guide groove 40 as the switching means S, the second swing member 24, and the second slider 32 constitute a push-open mechanism B.

In a state where the drawer D shown in FIG. 14 is fully closed (see also FIG. 11), the switching means S is engaged with the first latching portion P1 (see FIG. 15) of the latching rod 31 guide groove 40. Is retained.
In the state shown in FIG. 16A in which the front surface of the drawer D is pushed to operate the push-open mechanism B from this state, the driven surface 24F of the second swing member 24 is pressed by the driving pin K, and the second swinging mechanism 24 is pressed. The second slider 32 on which the second latching body 24B of the moving member 24 is latched in the latching groove 32C is also pushed and moved, and the switching rod S causes the latching rod 31 to move to the second latching portion of the guide groove 40. When switching to the state of FIG. 16 (b) hooked on P2 (see FIG. 15), the second swing member 24 swings forward around the second horizontal support shaft 22B.

  Therefore, from the first slide position of the second slider 32 where the amount of elastic deformation of the second elastic member 28 where the latch rod 31 is located at the first latch portion P1 is large, the latch rod 31 is moved to the second latch portion P2. When the second elastic member 28 positioned is switched to the second slide position of the second slider 32 where the elastic deformation amount is small, the elastic energy of the second elastic member 28 is released, and the restoring force of the second elastic member 28 is the second. The drive pin K is pushed forward (in the direction of opening the drawer D) by acting on the drive pin K from the driven surface 24F of the swing member 24 and the pressing surface 32F of the second slider 32, and the second swing member 24. Swings and the drive pin K is disengaged from the hook-like engagement portion 24E, so that the drawer D is automatically opened. The drive pin K is pushed and urged by the pressing surface 32F of the second slider 32 as indicated by a two-dot chain line in FIG. 16B, and the first swing member 23 of the first swing member 23 is indicated as indicated by a solid line in FIG. It moves to the back of the driven surface 23D.

In the state of FIG. 16B, the drawer D is open in a range up to the position where the drive pin K contacts the driven surface 23D of the first swing member 23. Therefore, as shown in FIG. Even without a handle or handle, for example, the drawer D can be opened by holding the upper edge of the front plate F of the drawer D.
With the operation of opening the drawer D, as shown in FIG. 17A, the driving pin K moves forward while pressing the driven surface 23D of the first swing member 23, and the first elastic members 25, 25 are moved. Is elastically deformed, and the first latching body 23B of the first swing member 23 is moved to the latching groove 34 while being guided by the sliding groove 33 of the base 21A, so that the first latching body 23B is moved to the latching groove. 34 is hooked.

In this state, the first rocking member 23 is rocked and latched, and the driven surface 23D of the first rocking member 23 is separated from the drive pin K, so the first elastic member 25, Without the restoring force of 25 acting, the drawer D (drive pin K) can be moved fully forward as shown in FIG. 17B.
17A and 17B, the first hooking body 23B of the first swing member 23 is hooked in the hooking groove 34, and the movement of the first slider 22 is stopped. Since the state is maintained, elastic energy is accumulated in the first elastic members 25 and 25 constituting the soft close mechanism A.

  When the drawer D is closed after the drawer D is fully opened, the driven surface 24F of the second rocking member 24 is pressed by the driving pin K as shown in FIG. Is switched from the second slide position to the first slide position, the drive pin K is engaged with the hook-like engagement portion 24E of the second swing member 24, and the second slider 32 is moved from the second slide position to the first slide position. In the middle of switching, the driving surface 24G of the second swing member 24 presses the driven surface 35C of the connecting member 35, and the connecting member 35 swings as shown in FIG. The member 23 swings around the first horizontal support shaft 22 </ b> A and the first hooking body 23 </ b> B comes off the hooking groove 34.

In this state, the restoring force of the first elastic members 25 and 25 and the braking force of the damper 26 are applied to the hook-like engagement portion 24E of the second swing member 24 through the first slider 22 and the second swing member 24. Since the transmission is transmitted to the driving pin K, the drawer D is automatically closed slowly and the drawer D shown in FIG. 14 is fully closed.
Here, a sliding pin 24C (see also FIG. 14) projecting from the right surface of the second swing member 24 shown in FIG. 13 passes through the slit 22J of the first slider 22 to form the base 21A shown in FIG. The sliding pin 24C is configured to move along a circumferential groove 41 (see also FIG. 14) formed on the left surface, and when the drawer D is opened, the sliding pin 24C is placed below the circumferential groove 41 in the drawer D. When closing the cover, it moves through the upper side of the circumferential groove 41, so that malfunction can be prevented.

According to the structure of the mechanism unit 21 incorporating the soft close mechanism and the push-open mechanism as described above, the first slide position and the second slide position of the second slider 32 where the elastic deformation amount of the second elastic member 28 is large by the switching means S. The second slide position of the second slider 32 with a small elastic deformation amount of the elastic member 28 is alternately switched and held, and when the push open mechanism B is operated, the second swing member 24 is moved by the drive pin K. The drawer D is automatically driven by the elastic energy of the second elastic member 28 that is released when the second elastic member 28 is operated to switch from the first slide position where the elastic deformation amount is large to the second slide position where the elastic deformation amount is small. Can be opened.
Further, when the soft closing mechanism A is operated, when the second swing member 24 is operated by the drive pin K and the second slider 32 is switched from the second slide position to the first slide position by the switching means S, The drive pin K engages with the hook-like engagement portion 24E of the second swing member 24, and the drive surface 24G of the second swing member 24 presses the driven surface 35C of the connecting member 35, via the connecting member 35. Since the first latching member 23B is detached from the latching groove 34 by swinging the first swinging member 23, the drawer D is automatically and slowly activated by the restoring force of the first elastic members 25 and 25 and the braking force of the damper 26. Can be closed.

Further, the two sliding positions of the second slider 32 are alternately switched by the switching means S, and the second swinging member in which the second latching body 24B is engaged with the sliding groove 32B and the latching groove 32C of the second slider 32. When the drive pin K presses the driven surface 24F of 24, the soft close mechanism A or the push open mechanism B operates, and when the soft close mechanism B is operated, the second swing member 24 swings. The first hooking body 23B of the seesaw-like first swinging member 23 is detached from the hooking portion 34 by interlocking the swinging of the seesaw-like connecting member 35 and the seesaw-like first swinging member 23. Since the soft closing mechanism A and the push-open mechanism B can be incorporated with a relatively simple and compact configuration, the manufacturing cost can be reduced. It can be used easily attached to the body C or drawer D of existing furniture or new furniture.
Furthermore, as compared with the first embodiment, the first rocking member 23 and the second rocking member 24 are connected by the connecting member 35, and the second slider is slidably supported by the first slider 22. 32, since the restoring force of the second elastic member 28 is applied to the drive pin K by the pressing surface 32F of the second slider 32, the stroke that is automatically opened by the push-open mechanism B can be increased. Since the hand can easily enter the drawer D, the operability can be improved.

The switching means S is connected to the second slider 32 so as to be swingable around a horizontal axis (connection pin 38) and extends in the opposite direction to the second elastic member 28. The guide groove 40 is constituted by a guide groove 40 that guides the end portion (the latch rod 31), and the guide groove 40 is connected to a circumferential groove portion that circulates the free end portion of the latch 29 in one direction, and a front end portion of the circumferential groove portion. The reciprocating groove portion extends in the front-rear direction and reciprocates the free end portion, and the middle of the circumferential groove portion is a first hooking portion P1 corresponding to the first slide position of the second slider 32, and the front end of the reciprocating groove portion This portion is a second hooking portion P2 corresponding to the second slide position of the second slider 32.
Therefore, the switching means S for alternately switching the two slide positions of the second slider 32 that are separated from each other so as to expand the stroke of the push-open mechanism B includes a latch 29 connected to the second slider 32, and a latch. It is realized by a simple configuration including a guide groove 40 that guides the free end portion of the stopper 29 and includes a circumferential groove portion provided with the first hook portion P1 and a reciprocating groove portion provided with the second hook portion P2. Therefore, it is possible to reduce the cost and ensure the operation.
