Each of the auxiliary link arms 32 and 34 includes connecting portions 32a and 34a that are rotatably connected to the support plate 26, and connecting portions 32b and 34b that are rotatably connected to the side surface of the lower drawer 16 respectively. Further, the connecting portion 34 a of the auxiliary link arm 34 can be locked with a rotation locking portion 30 f of the main link arm 30 in accordance with the rotation state of the main link arm 30.

In addition, the sliding mechanism 20 and the lifting mechanism 22 incorporate an operation regulating mechanism 36 that cooperates with them to regulate either the sliding of the lower drawer 16 by the sliding mechanism 20 or the lifting of the lifting mechanism 22. It is. The operation restricting mechanism 36 is a mechanism that serves as both a lift restricting mechanism and a sliding restricting mechanism, and specifically includes a switching arm 38 and a guide locking member 40.
The switching arm 38 is disposed so as to extend in the depth direction substantially parallel to the inner surface of the support plate 26, and is movable in the front-rear direction integrally with the support plate 26, and from the center of the switching arm 38. In addition, a rotation shaft 38a is provided at a position slightly deviated to the rear side, and is rotatable with respect to the inner surface of the support plate 26.
The guide locking member 40 is fixed immediately below the front end 24a of the fixed rail 24 of the inner wall surface 18a of the cabinet body 18, and a guide locking groove 40a is formed. The guide locking groove 40a is formed so as to open toward the back side and to curve downward from the back side toward the front side. As shown in FIG. 4, in a state where the lower drawer 16 and the support plate 26 are housed in the cabinet body 18, the switching arm 38 is in a posture extending substantially horizontally, and the front end portion 38 b of the switching arm 38 is It is fitted in the fitting recess 30 b of the main link arm 30 of the lifting mechanism 22. At this time, the protrusion 38c at the rear end portion of the switching arm 38 is located away from the guide locking groove 40b of the guide locking member 40 and is in an unlocked state.
On the other hand, as shown in FIG. 3, when the support plate 26 is completely pulled out from the cabinet body 18, the projection 38 c at the rear end of the switching arm 38 reaches the position of the guide locking groove 40 a of the guide locking member 40. To do. Thereafter, the projection 38c at the rear end portion of the switching arm 38 is guided and locked downward along the guide locking groove 40a of the guide locking member 40 toward the front side. Is prevented (restricted), and the front end 38b of the switching arm 38 rotates upward, so that the front end 38b of the switching arm 38 and the fitting recess 30b of the main link arm 30 are fitted together. It is configured to be released.

Further, a gas spring 42 is attached to the support plate 26 to assist the raising / lowering of the lower drawer 16 by the raising / lowering mechanism 22. The gas spring 42 includes a piston rod 42a that expands and contracts in the axial direction.
As shown in FIG. 4, when the lower drawer 16 and the support plate 26 are housed in the cabinet body 18, the gas spring 42 has its tip 42b in a state where the piston rod 42a is pre-compressed in the axial direction. Are connected by a connecting portion 30 c of the main link arm 30.
Further, the gas spring 42 is rotatable with respect to the support plate 26 at a fulcrum 42c. Further, the gas spring 42 has a direction (axial direction of the gas spring 42) connecting from the fulcrum 42c to the connecting portion 30c of the main link arm 30 more than a direction connecting the fulcrum 42c to the rotation shaft 30a of the main link arm 30. It arrange | positions diagonally with respect to the support plate 26 so that it may become slightly upward (refer FIG. 4). For this reason, the piston rod 42a of the gas spring 42 urges the connecting portion 30c of the main link arm 30 in the axial direction of the gas spring 42 with a predetermined urging force F0. The vertical component F0v is generated as a slight upward force (see FIG. 4).

Next, the operation (action) of the cabinet according to the first embodiment of the present invention described above will be described.
FIG. 5 is an enlarged partial cross-sectional view similar to FIGS. 3 and 4, showing a state in which the rise starts or ends after the lower drawer is completely drawn out in the cabinet of the present embodiment. FIG. 6 is an enlarged partial cross-sectional view similar to FIGS. 3 to 5, showing a state in which the lower drawer fully pulled out from the cabinet of the present embodiment is being lifted and lowered. FIG. 7 is a side view showing the positional relationship between the main link arm, the switching arm, and the guide locking member in the first embodiment of the present invention.
First, as shown in FIG. 4, in a state where the lower drawer 16 is completely accommodated in the cabinet body 18, the switching arm 38 of the operation restricting mechanism 36 has the left side portion on the right side with the rotation shaft 38a as the center. Since the gravity is greater than that of the portion, the front end portion 38b is fitted into the fitting recess 30b of the main link arm 30 by gravity and is disposed substantially parallel to the fixed rail 24 and the sliding rail 28. . Further, in the connecting portion 30c of the main link arm 30, the piston rod 42a of the gas spring 42 urges the connecting portion 30c of the main link arm 30 in the axial direction above the gas spring 42 with a predetermined urging force F0. An upward biasing force F0v is slightly generated by the vertical component F0v of F0. Further, the slight upward biasing force F0v generates a slight torque T0 that attempts to rotate the main link arm 30 shown in FIG. 4 counterclockwise around the rotation shaft 30a.

Next, as shown in FIG. 5, when the lower drawer 16 is pulled forward (front side) with respect to the cabinet body 18, the support plate 26 that indirectly supports the lower drawer 16 together with the slide rail 28. It slides along the fixed rail 24 on the cabinet body 18 side.
At this time, since the main link arm 30, the switching arm 38, and the guide locking member 40 are in the positional relationship shown in FIG. 7A, the lifting and lowering of the drawer 16 by the lifting mechanism 22 is performed during sliding. Regulated.
Specifically, the front end portion 38b of the switching arm 38 and the fitting recess 30b of the main link arm 30 are fitted until the support plate 26 is pulled out to the maximum extent from the cabinet body 18 to the front side. Since the state remains as it is (see FIG. 7A), the link arms 30, 32, 34 and the gas spring 42 of the elevating mechanism 22 are stationary without rotating with respect to the support plate 26. That is, when the support plate 26 is slid with respect to the cabinet body 18 by the sliding mechanism 20, the lower drawer 16 is also integrated with the support plate 26 via the link arms 30, 32, 34 of the elevating mechanism 22. 18, the lower drawer 16 is not lifted or lowered by the lifting mechanism 22 until the support plate 26 is fully pulled out from the cabinet body 18 to the front side.
Next, the lower drawer 16 is pulled out to the front side until the back surface portion 16b of the lower drawer 16 is positioned in front (front side) of the front portion 14a of the middle drawer 14, and the support plate 26 is integrated with the lower drawer 16 in the cabinet. When pulled out from the main body 18 to the front side as much as possible, the projection 38c at the rear end of the switching arm 38 moves along the guide locking groove 40a of the guide locking member 40 as shown in FIG. It is guided downward and locked to the lower end of the guide locking groove 40a. As a result, the switching arm 38 pivots clockwise with respect to the support plate 26 around the pivot shaft 38a, and the front end portion 38b of the switching arm 38 and the fitting recess 30b of the main link arm 30 are fitted. Canceled.

  Further, the lower plate 16 is pulled out in a state where the support plate 26 is pulled out from the cabinet body 18 to the front side to the maximum and the fitting between the front end 38b of the switching arm 38 and the fitting recess 30b of the main link arm 30 is released. When pulled further to the front side, a force F1 pulling the connecting portion 30d of the main link arm 30 to the front side acts, and the main link arm 30 is moved by the distance between the rotating shaft 30a of the main link arm 30 and the connecting portion 30d and the force F1. A torque T1 is generated to rotate clockwise about the rotation shaft 30a. The main link arm 30 generated by the gas spring 42 disposed on the support plate 26 in the state in which the torque T1 of the rotary shaft 30a of the main link arm 30 is housed in the cabinet body 18 is rotated counterclockwise around the rotary shaft 30a. When the torque T0 to be rotated is exceeded, the main link arm 30 starts to rotate clockwise around the rotation shaft 30a. At the same time, the auxiliary link arms 32 and 34 also rotate clockwise around the connecting portions 32a and 34a with the support plate 26, and the raising and lowering mechanism 22 starts to raise the lower drawer 16 with respect to the support plate 16, and lower drawer. 16 is in a rising state as shown in FIG. At this time, the main link arm 30, the switching arm 38, and the guide locking member 40 are in the positional relationship shown in FIG.

Next, as shown in FIG. 6, when the main link arm 30 rotates clockwise around the rotation shaft 30a and the lower drawer 16 is moving up, the piston rod 42a of the gas spring 42 extends in the axial direction. Therefore, the axial force F2 of the piston rod 42a acts on the connecting portion 30c of the main link arm 30. Due to the axial force F2 of the piston rod 42a, a torque T2 for rotating the main link arm 30 clockwise acts on the rotation shaft 30a of the main link arm 30. These forces F2 and torque T2 assist the further raising of the lower drawer 16 in the middle of the rise shown in FIG.
Further, when the lower drawer 16 is being lifted, the projection 38c at the rear end of the switching arm 38 is held in the state of being locked to the lower end of the guide locking groove 40a. 18 is maintained in a state where it cannot slide in the depth direction at all. Further, when the main link arm 30 rotates clockwise around the rotation shaft 30a, the auxiliary link arms 32 and 34 also rotate clockwise around the connecting portions 32a and 34a. The drawer 16 has a back surface portion 16b located at a predetermined distance from the front surface portion 14a of the middle drawer 14 at a predetermined distance. Accordingly, the back surface portion 16b of the lower drawer 16 and the front portion 14a of the middle drawer 14 are not in contact at all.
Further, when the lower drawer 16 is lifted upward by grasping the grasping portion 16a of the lower drawer 16 shown in FIG. 6, an upward force F3 acts on the connecting portion 30d of the main link arm 30 and the like. Due to the force F3, a torque T3 for further rotating the main link arm 30 clockwise acts on the rotation shaft 30a of the main link arm 30. When the main link arm 30 is rotated clockwise around the rotation shaft 30a by the torque T3, the auxiliary link arms 32 and 34 are also rotated clockwise around the connecting portions 32a and 34a, and the lower drawer 16 As shown in FIG. 3, the height rises to a use height (top height) that is substantially the same height as the middle drawer 14.

Next, as shown in FIG. 3, when the lower drawer 16 reaches the highest position (use height), the lower drawer 16 is completely lifted. In the lowermost drawer 16 at the uppermost position, the back surface portion 16b is positioned in front of the front surface portion 14a of the middle drawer 14. Further, the projection 38c at the rear end of the switching arm 38 is also maintained in the state of being locked to the lower end of the guide locking groove 40a, and the support plate 26 is also slid in the depth direction with respect to the cabinet body 18. It is kept in a state where it cannot. Further, since the rotation locking portion 30f of the main link arm 30 is formed in a C-shape, when the lower drawer 16 reaches the uppermost position (use height), the rotation locking portion 30f is connected to the link arm 34. The connecting portion 34a is securely connected, and the rotation of the main link arm 30 around the rotation shaft 30a is reliably locked. Therefore, the lock is not released until a force greater than a predetermined force for releasing the lock is applied to the rotation lock 30f, so that the lower drawer 16 can be prevented from inadvertently descending and the lower drawer can be prevented. The back surface portion 16b of the 16 and the front surface portion 14a of the middle drawer 14 are not in contact at all.
Further, in a state where the lower drawer 16 is raised to the uppermost position, the piston rod 42a of the gas spring 42 tends to further extend in the axial direction thereof, so that the piston rod 42a pushes the connecting portion 30c of the main link arm 30 with a biasing force F4. Thus, it is biased in the axial direction of the piston rod 42a. Therefore, the vertical component F4v of the urging force F4 by the piston rod 42a is generated as a slight upward force, and is a force that prevents the lower drawer 16 that has been raised to the uppermost position from inadvertently suddenly descending. Yes.

Next, an operation from the state in which the lower drawer 16 is raised to the uppermost position (see FIG. 3) to the state in which it is stored in the original cabinet body 18 (see FIG. 4) will be described.
When the grip 16a of the lower drawer 16 is grasped and the entire lower drawer 16 is pulled in the front direction, a tensile force F5 in the horizontal front direction acts on the connecting portion 30d of the main link arm 30 and the like. The pulling force F5 generates a torque T5 that causes the main link arm 30 to rotate counterclockwise about the rotation shaft 30a, and a connecting portion between the rotation locking portion 30f of the main link arm 30 and the link arm 34. The locking with 34a is released. When the main link arm 30 starts to rotate counterclockwise about the rotation shaft 30a, the auxiliary link arms 32 and 34 simultaneously rotate about the connecting portions 32a and 34a, and the entire lower drawer 16 descends from the uppermost position. Begin to. At this time, an axial biasing force F4 due to the piston rod 42a of the gas spring 42 is generated in the connecting portion 30c of the main link arm 30, and the upward force due to the vertical component F4v is inadvertently caused by the lower drawer 16 being careless. It is a force that prevents a sudden drop (see FIG. 3).

Next, as shown in FIG. 6, when the lower drawer 16 is in the descending state, the projection 38c at the rear end of the switching arm 38 is located at the lower end of the guide locking groove 40a, as in the ascending state. The support plate 26 is maintained in a locked state, and the support plate 26 is also maintained in a state where it cannot slide in the depth direction with respect to the cabinet body 18. Further, the main link arm 30 rotates counterclockwise around the rotation shaft 30a, and the auxiliary link arms 32, 34 also rotate counterclockwise around the connecting portions 32a, 34a. The lower drawer 16 has a back surface portion 16b located at a predetermined distance from the front surface portion 14a of the middle drawer 14 at a predetermined distance, and the lower drawer 16 is positioned in front of the lower drawer 16 and the front surface of the middle drawer 14. The part 14a does not contact at all.
Further, when the gripper 16a of the lower drawer 16 in the descending state shown in FIG. 6 is grasped and the entire lower drawer 16 is pushed downward, a downward downward force F6 is applied to the connecting part 30d of the main link arm 30 and the like. Works. The pushing force F6 generates a torque T6 that attempts to rotate the main link arm 30 counterclockwise about the rotation shaft 30a. The torque T6 further causes the main link arm 30 to counteract about the rotation shaft 30a. While rotating clockwise, the auxiliary link arms 32 and 34 simultaneously rotate around the connecting portions 32a and 34a, so that the entire lower drawer 16 is stored in the original cabinet body 18 in the lower drawer 16. The height is lowered to the same height, that is, the drawer height (see FIG. 5).

Next, as shown in FIG. 5, when the lower drawer 16 being lowered is lowered to the drawer height, the fitting recess 30b of the main link arm 30 can receive the front end 38b of the switching arm 38 in the vicinity thereof. It becomes.
In this state, when the grip 16b of the lower drawer 16 is grasped and the drawer 16 is pushed in the depth direction, the switching arm 38 moves in the depth direction, so that the protrusion 38b at the rear end of the switching arm 38 is guided by the guide locking member 40. From the state locked in the guide locking groove 40a, it moves along the groove 40a to the entrance of the groove located at the rear upper side, and the locking by the guide locking groove 40a is released. At this time, the switching arm 38 rotates counterclockwise about the rotation shaft 38 a, and the front end portion 38 c of the switching arm 38 is fitted into the fitting recess 30 b of the main link arm 30.
As described above, when the protrusion 38b at the rear end of the switching arm 38 is unlocked by the guide locking groove 40a, the front end 38b of the switching arm 38 is fitted into the fitting recess 30b of the main link arm 30. Therefore, the lower drawer 16 cannot be lifted or lowered by the lifting mechanism 22 at all, and only the sliding of the lower drawer 16 and the support plate 26 in the depth direction by the sliding mechanism 20 is possible.
Further, when the grip 16a of the lower drawer 16 in this state is grasped and the entire lower drawer 16 is pushed in the depth direction, the slide rail 28 of the support plate 26 that indirectly supports the lower drawer 16 is moved to the cabinet body 18. It slides in the depth direction along the fixed rail 24 on the side, and the lower drawer 16 and the support plate 26 are completely accommodated in the cabinet body 18 (see FIG. 4).

According to the cabinet 1 according to the first embodiment of the present invention described above, when the contents of the lower drawer 16 located at a position lower than the knee portion of a general adult user in the state of being housed in the cabinet body 18 are taken out, In the state where the lower drawer 16 of the drawer height is completely pulled out from the cabinet body 18, it is almost the same as the height of the middle drawer 14 located at a height of a general adult user's knee portion or higher. Since it can be raised to the use height, when taking out the contents of the lower drawer 16, it is possible to reduce the work load such as bending and taking an unreasonable posture.
Moreover, according to the cabinet 1 of 1st Embodiment, the operation control mechanism 36 which served as the raising / lowering regulation mechanism and the sliding regulation mechanism cooperates with the sliding mechanism 20 and the raising / lowering mechanism 22, and was accommodated in the cabinet main body 18.

FIG. 10 is a partial plan view similar to FIG. 8 showing the operating states of the sliding mechanism, the lifting mechanism, and the operation restricting mechanism of one side portion of the lower drawer in the cabinet of the second embodiment. FIG. 11 is a cross-sectional view taken along the line XI-XI in FIG. 10 and 11, the same reference numerals are given to the same portions as the cabinet portions of the first embodiment, and the description thereof is omitted.
First, as shown in FIGS. 8 and 9, when the lower drawer 16 of the cabinet 50 of the present embodiment is pulled forward (front side) with respect to the cabinet body 18, the lower drawer 16 is connected via the main link arm 60 and the like. The support plate 26 that is indirectly supported slides forward (to the front side) along the fixed rail (not shown) on the cabinet body 18 side together with the slide rail (not shown). At this time, the switching arm 62 also slides integrally with the support plate 26, but the cam member 64 and the stopper 66 remain until the rear end 62b of the switching arm 62 is locked by the locking projection 68. Does not rotate with respect to the support plate. That is, the stopper 66 does not contact the guide locking member 58 on the cabinet body 18 side at all, and makes the support plate 26 slidable with respect to the cabinet body 18. The front end 62c of the switching arm 62 is fitted in the fitting recess 60b of the main link arm 60, and is locked so that the main link arm 60 does not rotate.

Next, when the lower drawer 16 in the state shown in FIGS. 8 and 9 is pulled further forward, the support plate 26 that indirectly supports the lower drawer 16 moves further forward with respect to the cabinet body 18 together with the switching arm 62. It slides and the rear end part 62b of the switching arm 62 will be in the state latched by the latching protrusion 68 (refer FIG. 10). In this state, when the lower drawer 16 is further pulled forward, the compression coil spring 70 of the switching arm support portion 26d is compressed, and the support plate 26 slides forward with respect to the switching arm 62 in the locked state.
When the support plate 26 slides forward with respect to the switching arm 62 in the locked state, the connecting portion 26b of the cam member 64 and the support plate 26 also moves forward with respect to the switching arm 62 and comes into contact with the stopper 66. The cam member 64 is rotated, and the stopper 66 is rotated counterclockwise around the connecting portion 26c and protrudes toward the cabinet body 18 (see FIG. 10). At this time, the tip end portion 66a of the stopper 66 extends to the vicinity of the stopper regulating projection 67 of the guide locking member 58 on the cabinet body 18 side, and the support plate 26 slides in the depth direction of the cabinet body 18 in such a state. If it is made to do, the edge part 66a of the stopper 66 and the stopper control protrusion 67 will collide, and the sliding to the depth direction of the support plate 26 will be blocked | prevented.

Further, when the stopper 66 prevents the support plate 26 from sliding in the depth direction, the fitting between the front end 62c of the switching arm 62 and the fitting recess 60b of the main link arm 60 is released. Then, the main link arm 60 rotates counterclockwise about the rotation shaft 60a, the lower drawer 16 is raised with respect to the support plate 26, and the lower drawer 16 can be moved up and down by the lifting mechanism 54 (FIG. 10 and FIG. 11).
Further, when the lower drawer 16 is being lifted and lowered by the lift mechanism 54, the state where the stopper 66 protrudes toward the cabinet body 18 side so as to prevent the support plate 26 from sliding in the depth direction is maintained (FIG. 10). reference).

On the other hand, when returning the raised lower drawer 16 to the original storage position of the cabinet body 18, the raised lower drawer 16 is lowered to the drawer height of the lower drawer 16 by the lifting mechanism 54. When the lower drawer 16 is lowered to the same height as the lower drawer 16, the main link arm 60 is oriented so that the fitting recess 60 b can receive the front end 62 c of the switching arm 62. In this state, when the support plate 26 is slightly pushed in the depth direction via the lower drawer 16, the switching arm 62 slides forward with respect to the support plate 26 by the biasing force of the compressed compression spring 70, The front end 62c is fitted into the fitting recess 60b of the main link arm 60, and the rotation of the main link arm 60 is locked (see FIG. 9).
Further, when the support plate 26 is slightly pushed in the depth direction and the switching arm 62 is slid forward with respect to the support plate 26, the cam member 64 is rotated, and the stopper 66 is rotated clockwise around the connecting portion 26c. To the lower drawer 16 side, and the collision between the stopper 66 and the stopper regulating projection 67 of the guide locking member 58 is avoided (see FIG. 8).
Accordingly, the lower drawer 16 can only be slid in the depth direction by the sliding mechanism 56 while the elevation of the lower drawer 16 by the lifting mechanism 54 is restricted, and the lower drawer 16 and the support plate 26 are completely inside the cabinet body 18. It is stored in.

  According to the cabinet 50 according to the second embodiment of the present invention described above, similarly to the cabinet 1 of the first embodiment, the operation restriction mechanism 56 cooperates with the sliding mechanism 52 and the lifting mechanism 54 and is stored in the cabinet body 18.
