Description

  The present invention relates to a cabinet with a drawer in which an outer drawer and an inner drawer are pulled out in conjunction with each other, and particularly relates to a cabinet with a drawer using a linkage mechanism suitable for reducing the operating force of the drawer.

  Conventionally, in order to effectively use the upper space of the drawer, a cabinet having an inner drawer in the upper space of the drawer is known. However, in order to open the inner drawer, the inner drawer is pulled out after the outer drawer is pulled out. One action was necessary and its usability was not good. In view of this, there has been known one having an interlocking mechanism in which the outer drawer and the inner drawer are pulled out in conjunction with each other. For example, the interlocking mechanism disclosed in Patent Document 1 starts to pull out the outer drawer and the inner drawer at the same time. In addition, the interlocking mechanism disclosed in Patent Document 2 starts to pull out the inner drawer together with the outer drawer when the outer drawer is pulled out until it is fully opened.

  In recent years, drawers attached to kitchens and bathroom vanities are mainly used so that the drawers can be reliably closed by urging them in the fully-closed direction by a biasing means such as a spring immediately before the drawers are fully closed. It has become to. While the drawer provided with this biasing means has the above-mentioned advantages, it is necessary to pull out the drawer against the drag of the biasing means such as a spring at the beginning of pulling out, and there is a demerit that the pulling operation becomes very heavy. is there.

  Here, as in Patent Document 1, the outer drawer and the inner drawer begin to be pulled out at the same time. When the biasing means is provided in the outer drawer, the biasing is performed in addition to the weight of the outer drawer and the inner drawer. Since it is necessary to pull out against the effectiveness of the means, there is a problem that the operation at the beginning of the drawing becomes very heavy.

  Further, as in Patent Document 2, when the outer drawer is pulled out just before it is fully opened, the inner drawer starts to be pulled out together with the outer drawer. When the outer drawer is provided with biasing means, the drawer is fully closed. In the process of moving from the state to the fully open state, the pulling operation is once lightened after the drag of the biasing means is not applied. Thereafter, when the outer drawer is further pulled out, the inner drawer starts to be pulled out, so that the drawer operation becomes heavy again. Thus, after the drawer operation becomes lighter, it becomes heavier again, which causes a problem that the drawer operability is deteriorated.

  The present invention has been made in view of the above-described problems, and even when an urging means is provided for a cabinet with a drawer in which the outer drawer and the inner drawer are pulled out in conjunction with each other, the drawing is started from the beginning to the end of the drawing. The object is to provide a cabinet with drawers that is easy to operate. More specifically, an object of the present invention is to provide a drawer-equipped cabinet that can relieve the operation force at the beginning of pulling out and does not become suddenly heavy again after the operation force for pulling out becomes light.

  In order to achieve the above object, according to the first aspect of the present invention, a cabinet body, an outer drawer provided in the cabinet body so as to be able to be drawn out, and an inner drawer provided in the inside of the outer drawer so as to be able to be drawn out. A drawer comprising: an interlocking mechanism in which the inner drawer is pulled out in conjunction with a pulling operation of the outer drawer; and a biasing means for biasing the outer drawer in the fully closed direction immediately before the outer drawer is fully closed The external drawer is a first area where the operating force for pulling out is increased under the influence of the biasing means, and the outer drawer is pulled out from the first area because the influence of the biasing means is eliminated. There is a second region where the operating force for lightening is reduced, and the interlocking mechanism is moved to the second mechanism as the outer drawer switches from the first region to the second region. It is characterized in that said outer drawer and the inner drawer begins drawn in conjunction I.

According to the present invention, since the outer drawer and the inner drawer do not start to be pulled out at the same time, in other words, the inner drawer starts to be pulled out later than the outer drawer, so that the operation force at the beginning of the drawer is reduced. Can do. In addition, since the inner drawer starts to be pulled out in conjunction with the influence of the biasing means provided in the outer drawer, it can be prevented from becoming heavy again after the drawer operation becomes lighter, A series of drawer operability from the start to the end of the drawer can be improved.
It should be noted that the internal drawer starts to be interlocked at the same time when the influence of the urging means is lost, or includes the case where the timing is slightly delayed after the influence of the urging means is lost. Even if the timing is slightly delayed, the reason why the effect of the present invention is exerted is that the user feels that even if the weight is lightened for a moment, strictly considering the drawing speed of the outside drawer. This is because there is no influence of the biasing means, and at the same time the operability equivalent to that when the inner drawer starts to be pulled out can be obtained.

  According to the present invention, even when the urging means is provided for the cabinet with the drawer in which the outer drawer and the inner drawer are pulled out in conjunction with each other, the operability from the start of the drawer to the end of the drawer is excellent. Cabinet can be provided. More specifically, it is possible to provide a drawer-equipped cabinet that can relieve the operation force at the beginning of pulling out and does not become heavy again suddenly after the operation force for pulling out becomes light.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a transparent perspective view showing the structure of a cabinet with drawers of the present invention.
The drawer-equipped cabinet includes a cabinet 100 whose front surface is open, an upper drawer 200 and an outer drawer 400 provided with a front plate that closes the opening, and an inner drawer 300 located above the outer drawer 400. The upper drawer 200 and the outer drawer 400 are configured to be slidable in the front-rear direction with respect to the cabinet 100 by slide rails (not shown), and the inner drawer 300 is slidable in the front-rear direction with respect to the cabinet 100 by the slide rails 305. It is configured. Further, the inner drawer 300 has a structure in which the inner drawer 300 is also pulled out by pulling out the outer drawer 400 by the interlocking mechanism 500. Accordingly, it is not necessary to individually pull out the inner drawer 300 by merely pulling out the outer drawer 400, and usability is improved.
All of the slide rails mentioned here have a soft close mechanism, and have a structure in which a brake is applied at the end of the closing operation. The soft-close mechanism is a mechanism that slowly and surely closes when the drawer is closed, and consists of a damper and a spring (biasing means) that biases the damper in the fully-closed direction. It is what.

The cabinet 100 is formed by two cabinet side plates 101, a cabinet back plate 102, a top plate (not shown for perspective view), and a cabinet bottom plate 104, and the front is open.
The outer drawer 400 has an outer decorative plate 401 that covers a part of the opening of the cabinet, left and right outer side panels 402, an outer bottom plate 403, an outer back plate 404, and outer decorative plates at both ends above the outer side panel 402. 401 and left and right outer gallery bars 405 fixed to the outer back plate 404.
The inner drawer 300 includes an inner front plate 301, an inner side panel 302, an inner bottom plate 303 (not shown), and an inner back plate 304. Further, an inner handle 306 is attached so that the inner front plate 301 is always offset by about 100 mm from the outer decorative plate 401, and a space in which a tall bottle can be stored in this space.

  Further, the inner drawer has a structure capable of changing the height, and its detailed disassembly is shown in FIG. A hook pin 307 protruding to the inner side panel 301 side is fixed to the slide rail 305 with a screw 308. On the other hand, a wavy groove 309 is formed in the inner side panel 301, and a bag path portion 310 formed in a bag path shape is formed at five locations of the groove 309. The inner drawer 300 can be maintained at a predetermined height by hooking the bag path 310 to the hook pin 307, and the height of the inner drawer 300 can be changed by changing the height at which the bag path 310 is hooked by the hook pin 307. Can be changed. Therefore, it becomes a drawer | drawer with good storability by changing height according to a user's storage thing.

The details of the periphery of the interlocking mechanism 500 (part A in FIG. 1) are shown in FIG. For the sake of explanation, a partly transparent diagram is used.
The interlocking mechanism 500 includes a lower rack 501 attached to the outer gallery bar 405, a lower gear 502 that meshes with the lower rack 501, an upper gear 520 that meshes with the lower gear 502, and an upper gear 520. An upper rack 504 attached to the meshing slide rail 305, a gear plate 507 in which a lower gear 502 and an upper gear 520 are rotatably attached, and a lower gear 502 and an upper gear that can be attached to the gear plate 507. The gear cover 508 that covers 520, the rack feed pin 505 that is rotatably attached to the upper rack 504, and the rack feed pin 505 are removed from the position shown in FIG. And a stopper 506 that suppresses clockwise rotation. The gear plate 507 is fixed to the cabinet side plate 101. Therefore, since most of the interlocking mechanism parts are separated from the drawer, there is no extra protrusion even if the drawer is removed, and damage during construction can be prevented.
The upper gear 520 has a plurality of protrusions 521 arranged on the circumference.

FIG. 5 is an enlarged view around the interlocking mechanism 500, and particularly shows the relative positions of gears, racks, rack feed pins, etc. in an easy-to-understand manner.
The lower rack 501, the lower gear 502, the upper gear 520, and the upper rack 504 are arranged in a substantially vertical direction so that the teeth mesh with each other. The rack feed pin 505 and the protruding portion 521 of the upper rack 520 are arranged so as to mesh with each other slightly outside. The outer drawer and the inner drawer can be interlocked by the combination of the rack and the gear and the combination of the rack feed pin and the protrusion.
Here, the interlocking mechanism 500 may not interlock the inner drawer. When the inner drawer is not linked, the outer gallery bar 405 to which the lower rack 501 is attached is rotated 90 degrees in the circumferential direction so that the lower rack 501 does not mesh with the lower gear 502. By doing so, only the outer drawer can be pulled out when the frequency of use of the outer drawer is high, and when the inner drawer is used, it can be pulled out by grasping the inner handle of the inner drawer.

Next, how the outer drawer and the inner drawer move by the interlocking mechanism will be described with reference to FIGS.
FIG. 7 shows the movement of the opening operation.
FIG. 7A shows the positions of the outer drawer 400 and the inner drawer 300 in the fully closed state. In this state, the lower rack 501 is located behind the lower gear 502, and the two are not engaged with each other. Further, the upper rack 504 is also located behind the upper gear 520, and the two are not engaged with each other.
Here, in the fully closed state, the inner front plate 301 of the inner drawer 300 is retracted by about 100 mm from the front decorative plate 401 of the outer drawer 400, and by securing this space, for example, a back like a one-eyed bottle. High storage can be stored.
FIG. 7B is a schematic view of the outside drawer 400 drawn out by about 50 mm from the fully closed state. The slide rail of the outer drawer 400 is separated from the spring of the soft close mechanism, and at the same time, the lower rack 501 starts to engage with the lower gear 502 for the first time, and the lower gear 502 rotates counterclockwise so that the upper gear 520 rotates clockwise. Start rotating.

  An enlarged view of the upper gear 520 and the upper rack 504 at this stage is shown in FIG. FIG. 8A shows that the upper gear 520 has started to rotate in the clockwise direction, and the upper gear 520 and the upper rack 504 are not engaged with each other. When the upper gear 520 further rotates clockwise from here, FIG. 8B is obtained. In FIG. 8B, one of the protrusions 521 protruding from the upper gear 520 comes into contact with the rack feed pin 505 so that the rack feed pin 505 attempts to rotate so as to be pushed forward, but is rotated by the stopper 506. Therefore, the rack feed pin 505 is pushed forward without being able to rotate. By this movement, the upper rack 504 fixing the rack feed pin 505 is pushed forward.

  FIG. 8C is a schematic view showing a state in which the rack feed pin 505 and the upper rack 504 are pushed forward, and the upper gear 520 and the upper rack 504 start to engage with each other. In this state, the upper rack 504 is pushed forward by the meshing of the upper gear 520 and the upper rack 504 from here. That is, the inner drawer 300 integral with the upper rack 504 is pushed forward.

FIG. 7C is a schematic diagram showing a state in which the lower rack 501, the lower gear 502, the upper gear 520, and the upper rack 504 are engaged with each other. When the outer drawer 400 is moved forward, the lower rack 501 integrated with the outer drawer 400 is moved forward, the lower gear 502 engaged therewith rotates counterclockwise, and the upper gear 520 rotates further clockwise. Then, when the upper rack 504 is pushed forward, the inner drawer 300 moves in the opening direction. At this time, since the upper rack 504 and the lower rack 501 have the same feed amount, the outer drawer 400 and the inner drawer 300 are pulled out at the same speed. Only one of the outer drawer 400 and the inner drawer 300 can be opened without stopping.
FIG. 7D is a schematic diagram showing a state in which the outer drawer 400 is opened to almost half. When opening up to this point, the lower rack 501 passes through the lower gear 502 and is not engaged. Therefore, when the lower rack 501 and the lower gear 502 are disconnected, the linkage between the outer drawer 400 and the inner drawer 300 is disconnected.
FIG. 7E shows a schematic diagram in a state in which only the outer drawer 400 is further pulled out therefrom. If it will be in this state, both the outer drawer 400 and the inner drawer 300 can be looked over at a time, and the listing property of a stored item will improve. That is, it is possible to look at the stored items that are likely to be forgotten at a glance, and the convenience of the user is improved.
FIG. 7F shows a schematic diagram when the inner drawer 300 is further pulled out. By grasping the inner handle 306 of the inner drawer 300 and pulling it up to this state in FIG. 7, the contents stored in the inner drawer 300 can be easily taken out.
Further, a schematic diagram when only the inner drawer 300 is pushed in is shown in FIG. By pushing the inner drawer 300 until the inner front plate 301 of the inner drawer 300 is located behind the outer back plate 404 of the outer drawer 400, the stored items in the outer drawer 400 can be easily taken out.

FIG. 6 shows the operating force of the slide rail having the soft close mechanism. Note that the overlapping portions of the lines are slightly shifted to make the display easier to see.
The horizontal axis in FIG. 6 represents the opening distance of the drawer from the fully closed state, and the vertical axis represents the operating force at that time. Here, a case where the drawer is slowly drawn, that is, a case where the opening speed of the drawer is slow is shown. The thin solid line does not have an inner drawer, that is, the operating force for one outer drawer. Since the spring of the soft close mechanism is stretched from 50 mm to 50 mm, the operating force increases in proportion to the amount of extension of the spring. Since it is separated from the spring at 50 mm, the operating force suddenly becomes light, and thereafter, the operating force is due to the sliding property of the rail. Thus, in the case of a rail with a soft close mechanism, a large operating force is required in the initial stage from the start of pulling up to about 50 mm due to its function.

The thick solid line on the graph of FIG. 6 shows the operating force when the interlocking mechanism is opened from the fully closed state in the embodiment of the present invention.
Moreover, the thin dashed-dotted line and the thin dotted line have shown the interlocking operation force of the prior art. A thin alternate long and short dash line indicates an operating force when the outer drawer is pulled out until immediately before being fully opened and then interlocked with the inner drawer. At the initial 50 mm, the operating force is increased to extend the spring of the soft drawer mechanism of the outer drawer, and once it has become lighter, the operating force is again applied to extend the soft closed spring of the inner drawer immediately before fully opening the outer drawer. Become heavier. For the user, it is necessary to release the force once it has become lighter and to apply the force again when the inner drawer is pulled out, and it feels as if the two drawers are pulled out separately, and the operability is poor.
On the other hand, the conventional technology with a thin dotted line shows the operating force when the outer drawer and the inner drawer are pulled out simultaneously. Since the spring of the soft close mechanism provided in the inner drawer and the outer drawer is simultaneously stretched from the beginning of the pulling up to 50 mm, an operating force that is about twice the operating force for one outer drawer is required, and the operability is poor.
Finally, when attention is paid to the change in the operating force in the embodiment of the present invention, the operating force (thick solid line) in the embodiment of the present invention is drawn out of the first 50 mm as described in the operation of the above-described embodiment. Only the spring of the soft close mechanism is extended, and immediately after that, it starts to interlock with the inner drawer, and the spring of the soft close mechanism of the inner drawer is extended. Therefore, it becomes a continuous operating force as shown in the figure, and as an operational feeling, it feels as if one drawer is pulled out. In addition, the peak value of the operating force has been reduced to about half that of the conventional technology with a thin dotted line, and both the outer drawer and the inner drawer can be pulled out with the operational feeling as if a single drawer is being pulled. .
The above effect is most effective when the inner drawer is interlocked almost simultaneously with the release of the soft close of the outer drawer. However, this is not always the only point. Considering the operation speed of the outer drawer, since the soft drawer of the outer drawer is released, preferably even if the inner drawer is interlocked after the gap of 0 cm or more and less than 8 cm, the user feels continuously, The feeling of operation is good. Particularly preferably, when the inner drawer is interlocked after a gap of 0 cm to 5 cm or less, the user feels it continuously, so the operational feeling is better. On the other hand, if there is a gap of about 8 cm or more, the user feels that the user is lightened and relieved and then re-engaged by interlocking with the inner drawer, and the operation feeling is poor.

The movement from when the drawer is opened to when it is fully closed will be described. Basically, when the outer drawer 400 is pushed in, the back surface of the outer decorative plate 401 of the outer drawer 400 comes into contact with the inner handle 306 of the inner drawer 300, and when the outer drawer 400 is further pushed in, the inner drawer 300 is also pushed.
Thereafter, when the lower rack 501 and the lower gear 502, and further the upper rack 504 and the lower gear 520 mesh with each other, the outer drawer and the inner drawer are pushed together by the gear. At the last 50 mm, the lower rack 501 and the lower gear 502 do not mesh with each other, but the outer drawer 400 is closed to the fully closed state by the soft close mechanism. Moreover, although there is a place where the upper rack 504 and the upper gear 520 do not mesh with each other on the inner drawer 300 side, it can be fully closed by the soft close mechanism.

  9, there are cases where only the inner drawer 300 is closed first. In this case, as shown in FIG. 10, the lower rack 501 and the lower gear 502 are engaged, and the upper gear 520 is counterclockwise. Rotate to. However, since the upper gear 520 and the upper rack 504 are not already engaged with each other, the inner drawer 300 does not move. As for the protrusion 521 of the upper gear 520 and the rack feed pin 505, as shown in FIG. 10, the rack feed pin 505 rotates clockwise and escapes from the protrusion 521 of the upper gear 520. Therefore, even if the upper gear 520 rotates in the closing direction, it does not interfere and get caught.

As shown in the above embodiment, in the cabinet with drawers of the present invention, the inner drawer is linked with the outer drawer to improve the usability of the inner drawer, and the outer drawer is fixed in the linked operation. By adopting a structure in which the interlocking of the inner drawer starts after being pulled out by a distance, it is possible to reduce the operating force at the beginning of pulling the drawer.
Further, by delaying the interlocking of the inner drawer as described above, it is possible to overlook the outer drawer and the inner drawer at a time when the drawer is opened.
In addition, since the inner drawer starts to be pulled out in conjunction with the influence of the biasing means provided in the outer drawer, it can be prevented from becoming heavy again after the drawer operation becomes lighter, A series of drawer operability from the start to the end of the drawer can be improved.
Further, by releasing the interlock after the outer drawer and the inner drawer are interlocked with each other for a certain distance, the outer drawer and the inside air drawer can be freely taken in and out after the release, so that the items stored in the inner drawer and the outer drawer can be easily taken in and out.
Further, by adopting a structure in which the height of the inner drawer can be varied, the storage space of the outer drawer and the inner drawer can be changed according to the user, and the usability is improved.
Furthermore, the interlocking mechanism has a structure that can select whether the inner drawer is to be interlocked or not, so that it can be set not to interlock when the external drawer is used frequently. User-friendly because it can be selected.
Further, by fixing the main part of the interlocking mechanism to the cabinet side, there is no extra protrusion even if the drawer is removed, and damage during construction can be prevented.

The mechanism for interlocking with the inner drawer delayed from the outer drawer is not limited to the above. For example, the rack feed pin and the protrusion can be simplified by interposing a one-way clutch on the shaft of the upper gear or the lower gear. Furthermore, if the gear ratio of the upper gear is made smaller than that of the lower gear, the peak value of the second peak of the solid line in FIG. 6 can be reduced.
Further, in the fully closed state, the inner drawer may be enlarged until the inner front plate of the inner drawer comes to a position where it substantially contacts the back surface of the outer decorative plate of the outer drawer. By doing so, when there is no tall storage item such as a bottle, it is possible to maximize the storage space by taking a large inner drawer. Also, the inner handle of the inner drawer can be removed.
Furthermore, the inner handle of the inner drawer may be as shown in FIG. The plate-like inner handle 306b is fixed to an arbitrary position in the horizontal direction so as to be hooked on the upper and lower ends of the inner front plate 301. In this way, it is possible to secure a space for a tall stored item on the near side of the outer drawer and set the inner handle 306b at a position where it does not interfere with the stored item. In the case of such an inner handle, in the state of FIG. 7D, a tall stored item stored on the front side of the outer drawer can be easily taken out without interfering with the inner handle 306b.

In the above embodiment, both the outer drawer and the inner drawer are provided with the soft close mechanism, but the present invention has the same effect as long as the soft close mechanism is provided only on the outer drawer. This is because even when pulling out an inner drawer that does not have a pull-in function, some force is required, such as static friction when starting to move and inertial force that accelerates to the speed expected by the user.
In addition, here, a soft-close mechanism with a built-in spring is taken as an example, but only a pull-in function without a damper function may be used. In addition, the pull-in function is not limited to a spring, but pull-in by tilting a rail, pull-in by a magnet, or the like can be considered.
