Description

Specification

Drawing device

Technical field

The present invention relates to a drawer device provided with a drawer that is housed in a case provided with an opening and that can be put in and out of the opening.

Background art

Conventionally, in a system kitchen, furniture, and the like, drawers are manually pulled out or stored. When the equipment frame has multiple drawers, such as a system kitchen, the bottom drawer may contain heavy items. This is particularly difficult for people with physical disabilities and the elderly.

[0003] For this reason, for example, Patent Document 1 includes a drawer driving mechanism that moves a drawer that is detachable with respect to the apparatus frame body in the drawer direction and the storage direction. This drawer drive mechanism is composed of a roller that is rotatably supported by the apparatus frame and a motor that rotates the roller, and uses the elastic force of the coil panel to bring the roller into contact with the drawer at a predetermined pressure. By rotating the roller with a motor, the drawer is automatically pulled out or moved in the storing direction by the frictional force generated between the drawer and the roller.

[0004] When the drawer is pulled out or stored depending on the rotation direction of the motor while the pulling force is applied, the drawing speed and the drawing (housing) speed are substantially the same. In consideration of impacts during storage, the pull-in speed cannot be made too fast. In other words, the withdrawal speed cannot be made very fast, and there is a concern that it will be easy to use considering the time it takes for the drawer to be withdrawn.

[0006] A first aspect of the present invention relates to a case in which an opening is provided in a drawer, a drawer that is housed in the case and can be put in and out of the opening, and a conductive member provided on a surface of the drawer An energization detection unit that detects energization of the energization member and transmits a signal, a receiving unit that is provided in the case and receives a signal from the energization detection unit, and between the case and the drawer An extrusion mechanism that is provided and falls down to the drawer side to push out the drawer from the case; and a control unit that receives a signal sent from the reception unit and controls the operation of the extrusion mechanism. To do.

In the first aspect of the present invention, when the energization member provided in the drawer is energized, a signal is transmitted from the energization detection unit to the reception unit. The signal received by the receiving unit is transmitted to the control unit. On the other hand, an extruding mechanism is provided between the case and the drawer, and the drawer is tilted toward the drawer side so that the case force is also pushed out. By connecting the push-out mechanism and the control device and receiving a signal sent from the receiving unit, the operation of the push-out mechanism is controlled.

In other words, when the drawer is pulled out of the case, when it comes into contact with the energizing member, the pushing mechanism is pushed down to the drawer side by the control device via the energization detecting unit and the receiving unit, and the drawer can also push out the case force. It becomes possible to pull out the drawer easily and quickly with a low load.

[0009] For this reason, it is possible to perform the pull-out operation easily even for people with physical disabilities and elderly people. Also, since the drawer is pushed out by the collapse of the push-out mechanism, the depth of the push-out mechanism is compared with the case where the drawer is pushed out by moving the piston in the cylinder and bringing the piston into contact with the cylinder, for example, using an air cylinder. The thickness in the direction can be reduced.

[0010] In the drawer device according to the first aspect of the present invention, a mouth mechanism for locking the drawer to the case and an operation unit for operating the lock mechanism may be provided.

[0011] In the above configuration, the lock mechanism locks the drawer to the case by the operation of the operation unit. This prevents the drawer from being opened (drawn) without permission. For example, you can prevent small children from opening the drawers without permission. The In addition, in the event of an earthquake, the drawer can be pulled out of the case due to shaking, and objects in the drawer can be prevented from popping out.

[0012] In the drawer device having the above-described configuration, the lock mechanism is further provided with a lock plate that is provided in the receiving unit and that is retracted by the operation unit, and is provided in the energization detection unit and is engaged with the lock plate. And a lock hole to be configured.

[0013] By providing the receiving unit with a lock plate and providing the energization detection unit with a lock hole that is engaged with the lock plate, there is no need to separately provide a lock mechanism for the drawer and the case, and the assembly work is easy.

[0014] In the drawing device according to the first aspect of the present invention, the push-out mechanism includes a motor that can rotate forward and reverse, an push-out member that can be tilted toward the draw-out side, and a rotational force from the motor. It may be configured to include a modification that converts the movement of the member to collapse.

[0015] In the drawer device having the above-described configuration, an extrusion member that can be tilted toward the drawer side is provided, and a rotational force from a motor that can rotate forward and backward is transmitted to the extrusion member. Then, the pushing member is brought down by the conversion mechanism, and the pushed-down pushing member is returned to the original position (the state before the fall). Here, when the push-out member that collapses when pulling out the drawer is returned to its original position, the pressing force when storing the drawer is added by the provision of the push-out member! What! /

[0016] In the drawing device according to the first aspect of the present invention, the push-out mechanism is connected to a shaft, and is attached to the draw-out side, an push-out member that can be tilted toward the draw-out side by rotation of the shaft, and the push-out member.

BEST MODE FOR CARRYING OUT THE INVENTION [0037] Next, a drawing device according to an embodiment of the present invention will be described.

[0038] FIGS. 1 to 3 show a box-shaped drawer 10 for a system kitchen to which the drawer device 130 is applied, and the drawer can be inserted into a case 12 having an opening. . Although not shown, a rail is disposed on the side wall 12A of the case 12 along the drawing direction of the drawer 10, and a roller (not shown) provided on the drawer 10 extends along the rail. It can be moved. The coefficient of friction is made as small as possible between the mouth and the rail so that the drawer 10 can move smoothly in the case 12.

A plate-like touch panel 16 is provided on the upper surface of the front plate 14 of the drawer 10 in parallel with the front plate 14 along the width direction of the drawer 10. On the surface of the touch panel 16, as shown in FIG. 4, a touch plate 18 and a GND plate (grounding side plate) 20 are alternately arranged along the vertical direction of the drawer 10, and the touch plate 18 and the GND plate are arranged. Between 20, projecting portions 22 projecting from the surfaces of the touch plate 18 and the GND plate 20 are projected.

[0040] Further, as shown in FIGS. 1 and 5, both ends of the touch panel 16 are provided with attachment portions 24 and 26 to the drawer 10, and are attached to the front plate 14 of the drawer 10 by screws (not shown). It can be installed. A cover 30 for blindfolding is provided on the mounting portions 24 and 26 so as to be rotatable with respect to the surface of the touch panel 16. When the touch panel 16 is attached, the cover 30 is closed and the screw looks I try not to be exposed. Here, a through hole 32 (to be described later) through which a driver or the like can be inserted is formed in the attachment portion 24 on the left side of the touch panel 16 in the drawing, and penetrates the front plate 14 of the drawer 10.

On the other hand, as shown in FIG. 6, FIG. 7A, and FIG. 7B, a power detection unit 31 can be attached to the back side of the front plate 14 of the drawer 10. A contact piece 36 that is in surface contact with the back side of the front plate 14 of the drawer 10 is formed on the bracket 34 provided in the energization detection unit 31, and the front plate 14 of the drawer 10 is formed by a screw (not shown). Mounted on the back side.

In FIG. 7A and FIG. 7B, a flange portion 38 protrudes toward the mounting piece 48 from the front side end portion of the contact piece 36, and the flange portion 38 has a rectangular shape. Hole 38A is formed. In addition, a long plate-like engagement piece 40 is provided from the upper end of the contact piece 36 so as to project at a right angle to the contact piece 36, and a rectangular shape is formed on the distal end side of the engagement piece 40. Lock hole 4 2 is formed.

[0043] From the upper part of the side end surface of the base (the contact piece 36 side) of the engagement piece 40, a rectangular flange portion 44 protrudes, and the flange portion 44 is formed with a rectangular locking hole 44A. Has been. Further, a flange portion 46 bent in a substantially L shape projects downward from the distal end portion of the engagement piece 40, and the distal end portion of the flange portion 46 is provided in parallel with the engagement piece 40. ing.

[0044] Further, from the lower part of the side end surface in the longitudinal center of the engagement piece 40, an attachment piece 48 bent in a substantially L shape downward is formed, and the distal end side of the attachment piece 48 is It is provided in parallel with the piece 40. A rectangular mounting hole 48A is formed at the distal end side of the mounting piece 48, and as shown in FIG. 15, an energization detecting device 50 electrically connected to the touch panel 16 is formed in the mounting hole 48A. It can be installed.

[0045] Then, by touching the touch plate 18 and the GND plate 20 across the convex portion 22 of the touch panel 16 at the same time, the difference in capacitance with respect to OV (GND) is detected by the energization detection device 50. If the difference is greater than or equal to a predetermined value, a signal is output from the transmitter 84 (see FIG. 8) provided in the energization detection device 50! /.

On the other hand, as shown in FIG. 6, the energization detection unit 31 is covered with a protective cover 52, and a not-shown locking portion provided on the protective cover 52 is hooked on the tip of the flange portion 46. In this state, the claw portion (not shown) of the protective cover 52 is locked in the locking hole 38A of the flange portion 38 and the locking hole 44A of the flange portion 44.

Thereby, the energization detecting device 50 and the like constituting the energization detecting unit 31 are covered and protected by the protective cover 52. Further, in this state, the protective cover 52 is formed with a through hole 54 having a substantially rectangular shape larger than the lock hole 42 at a position corresponding to the lock hole 42 of the engagement piece 40. The through hole 54 is formed from the center in the longitudinal direction of the engagement piece 40 to the tip of the engagement piece 40. That is, the engagement piece 40 of the bracket 34 is exposed to the outside through the through hole 54.

On the other hand, on the case 12 side, the lock unit 56 is arranged at a position facing the energization detection unit 31 in a state where the drawer 10 is housed. The lock unit 56 is provided with a bracket (not shown), and a solenoid 58 is disposed on the bracket. ing.

[0049] In the solenoid 58, when the lock switch 134 is turned ONZOFF, the plunger 60 is moved in and out. The solenoid 58 is designed such that the plunger 60 is pulled by a permanent magnet, and the magnetic force of the permanent magnet is canceled by energization. I'm getting back. At this time, energization ends in an instant. However, when the magnetic force of the permanent magnet is restored and the plunger 60 is retracted, the energization is reversed between positive and negative. Also at this time, energization ends in an instant.

As shown in FIGS. 6, 7A, and 7B, a substantially prismatic shaft 64 having a connecting portion 61 at the base is connected to the distal end portion of the plunger 60, and is integrated with the plunger 60. Move to the slide. A shaft portion 66 orthogonal to the shaft 64 is disposed at the lower portion of the shaft 64, and the shaft portion 66 is engaged with the outer wall of the shaft 64 so as to wrap around, and the upper portion is opened. Member 68 is pivotally supported. The operating member 68 swings about the shaft portion 66 as the shaft 64 moves.

[0051] Further, a lock plate 72 having an engagement claw 70 formed at the free end is pivotally supported on the shaft 66 so that the lock plate 72 can swing. A notch 74 is formed at the base of the lock plate 72. The operation pin 76 formed and projecting from the outer surface of the operation member 68 is engageable. As a result, when the operating member 68 swings due to the movement of the shaft 64, the operating pin 76 swings through the operating member 68, and the lock plate 72 swings through the notch 74.

Further, a torsion panel 62 is wound around the shaft portion 66, one end portion is attached to a bracket (not shown) constituting the mouthpiece unit 56, and the other end portion is attached to the lock plate 72. The lock plate 72 is urged in the direction of arrow A (see FIG. 7B).

Here, the engaging claw 70 can be inserted into a through hole 54 (see FIG. 6) formed in the protective cover 52, and passes through the through hole 54 to be engaged with the engagement piece. It can be engaged with 40 lock holes 42. That is, by the rocking of the lock plate 72, the engaging claw 70 passes through the through hole 54 and engages with the hole 42 (locked state), or the engagement state with the lock hole 42 is released ( (Unlocked state) It can come out from the through hole 54.

[0054] The lock unit 56 is protected by a protective cover 80, and the lock plate 72 and the tip end surface of the shaft 64 can be moved in and out of the protective cover 80. Yes. Note that the engagement state between the lock unit 56 and the protective cover 80 is substantially the same as the engagement state between the energization detecting device 50 and the protective cover 52, and thus the description thereof is omitted here.

Incidentally, as shown in FIG. 6, the front end surface of the shaft 64 corresponds to the position of the through hole 32 formed in the mounting portion 24 of the touch panel 16, and a rod-like object such as a screwdriver from the through hole 32. When 33 is inserted, the rod 33 is brought into contact with the front end surface of the shaft 64.

[0056] For this reason, when the engaging claw 70 of the lock plate 72 is engaged with the lock hole 42, the rod-shaped object 33 is brought into contact with the distal end surface of the shaft 64, and when the shaft 64 is pressed, the plunger 60 is It can be pushed into the body of the solenoid 58 and the shaft 64 can be slid.

Thus, as the shaft 64 moves, the operation member 68 rotates about the shaft portion 66, and the operation pin 76 of the operation member 68 rotates to counteract the urging force of the torsion panel 62 ( The lock plate 72 swings in the direction opposite to the direction of arrow A), and the engagement state of the engagement claw 70 with the lock hole 42 can be released.

By the way, a signal from an earthquake detection sensor (seismic sensor) 128 provided in the system kit body is input to a control device 88 (described later) provided in the back wall of the case 12. When the signal from the seismic sensor 128 is input to the control device 88, the solenoid 58 of the mouth unit 56 is energized, the magnetic force of the permanent magnet is canceled, and the plunger 60 is pushed out. I am doing so. As a result, the lock plate 72 is locked in the lock hole 42 (in a clogged state).

[0059] Here, the stroke over which the lock plate 72 gets over the engagement piece 40 of the bracket 34 exposed to the outside through the through hole 54 is shorter than the stroke for sliding the plunger 60 of the solenoid 58. And speak.

[0060] Therefore, when the drawer 10 is pulled out from the case 12 and the lock plate 72 is placed in the locked position (the locked position), the drawer 10 is stored in the case 12 The force with which the distal end of the engagement piece 40 comes into contact with the inclined surface 70A of the distal end of the engagement claw 70 of the lock plate 72 The lock plate 72 is resisted against the urging force of the torsion panel 62 through the inclined surface 70A. Try to swing in the direction of

[0061] At this time, the plunger 60 of the solenoid 58 can be pushed into the main body of the solenoid 58 through the notch 74, the operation pin 76 and the shaft 64 of the lock plate 72. As a result, the lock plate 72 can swing, and the engagement piece 40 can be moved over. That is, the engaging claw 70 of the lock plate 72 gets over the engaging piece 40 and is locked by the lock hole 42, so that the lock plate 72 can be locked.

As described above, the lock unit 56 is provided with the lock plate 72, and the energization detection unit 31 is provided with the lock hole 42 that is locked to the lock plate 72, so that a separate opening mechanism is provided for the drawer 10 and the case 12. It is easy to assemble without having to be provided.

[0063] On the other hand, as shown in FIGS. 8 and 9, the lock unit 56 is provided with a receiving unit 82, and the receiving unit 82 and the transmitting unit 84 are in a state where the drawer 10 is stored. Face to face. Here, a coil is disposed in each of the transmission unit 84 and the reception unit 82, and a current flows through the coil on the reception unit 82 side by the supply of power.

[0064] When the touch plate 18 and the GND plate 20 of the touch panel 16 are simultaneously brought into contact with the transmitter 84 and the receiver 82 close to each other, the coil on the transmitter 84 side is electromagnetically induced by the receiver 82 side. A current flows through the transmitter 84, and the magnetic field fluctuates on the transmitter 84 side. The power supply to the touch panel 16 is detected and a signal is transmitted to the receiver 82.

[0065] In this manner, by enabling the transfer of electromotive force by electromagnetic induction, for example, although not shown, the transmitter 84 and the receiver 82 are electrically connected by a harness or the like. Unlike the drawer 10, the drawer 10 can be completely removed from the case 12, which is very convenient.

[0066] A harness 86 is connected to the receiving unit 82. The harness 86 is pulled out from the protective cover 80 and connected to a control device 88 provided on the back wall of the case 12. The transmitting unit 84 receives the receiving unit. When a signal is input to 82, this information is transmitted to the control device 88. When a signal is input to the control device 88, the drive motor 92 constituting the drive unit 90 (extrusion device) provided in the control device 88 is driven.

Here, the drive unit 90 will be described.

As shown in FIG. 10, a worm 94 is connected to the drive motor 92 so that the drive force of the drive motor 92 is transmitted. A worm wheel 96 is engaged with the worm 94, and a rotational force is transmitted to a shaft 97 that fixes the worm wheel 96.

[0069] A small gear 98 is fixed to the shaft 97, and when the small gear 98 rotates, The meshing large gear 100 rotates. The rotation of the large gear 100 causes the shaft 102 that fixes the large gear 100 to rotate, and the bevel gear 104 fixed to the shaft 102 rotates.

A force gear 105 meshes with the force gear 104, and a shaft 108 arranged perpendicular to the shaft 102 is fixed by the rotation of the force gear 105. It is designed to rotate. It should be noted that the gear train is not limited to this as long as the rotational force from the drive motor 92 can be reduced.

Further, one end portion of an extrusion plate 110 formed in a substantially rectangular shape is fixed to the shaft 108, and the extrusion plate 110 can be rotated with the rotation of the shaft 108. A roller 110A is rotatably supported at the free end of the extrusion plate 110 so that it can come into contact with the rear plate 15 of the drawer 10 (see FIGS. 12C and 12D).

Here, FIGS. 12A, 12C, and 12E are plan views showing the drawing device 130, and FIGS. 12B, 12D, and 12F are side views showing the drawing device 130 corresponding to FIGS. 12A, 12C, and 12E, respectively. FIG.

On the other hand, the force gear 104 has a notch 104A formed in a part in the circumferential direction. As shown in FIG. 11A, the force gear 104 has a force at a position corresponding to the notch 104A force bevel gear 105. The teeth of the force gear 104 are not meshed with the gear 105, and the driving force from the driving motor 92 is not transmitted. That is, the shaft 108 does not rotate.

[0073] Further, the shaft 108 is hooked with a spring 106 extending in a direction orthogonal to the shaft 108. The spring 106 is bent in a substantially L shape, and one of the springs 106A is in contact with the main body frame 108 of the drive unit 90, and the other 106B is in contact with the pushing plate 110, as shown in FIG. 11C. The natural state of the spring 106 is a state where one side 106A and the other side 106B are opened about 60 degrees.

[0074] For this reason, the elastic force is accumulated in the spring 106 in a state where the extruded plate 110 is closed with respect to the main body frame 88A. When the pusher plate 110 is closed with respect to the main body frame 108, the drive motor 92 stops driving, and the force gear 104 and the force gear 105 are slightly engaged (see FIG. 11B). The shaft 108 is locked by the squeezing, and the closed state of the extruded plate 110 is maintained. Then, when an electric signal is input to the control device 88 and the drive motor 92 is driven, the notch 104A of the force gear 104 corresponds to the force gear 105 (see FIG. 11A). That is, the locked state is released, and the force gear 105 and the shaft 108 are in a free state.

[0076] For this reason, due to the restoring force of the spring 106, the pushing plate 110 rotates about 60 degrees in the direction of arrow B (see Fig. 11C) around the shaft 108 and falls forward (drawer 10 side). It becomes. From this, as shown in FIGS. 12C and 12D (FIG. 12C) is a plan view showing the drawing device 130, and FIG. 12D is a side view showing the drawing device 130). The drawer 10 is pushed out of the case 12 while the roller 110A provided at the free end is in contact with the rear plate 15 of the drawer 10.

As described above, the rotation of the drive motor 92 causes the tooth portion 104B and the notch portion 104A of the force gear 104 to alternately correspond to the force gear 105, and the tooth portion 104B corresponds to the bevel gear 105. Correspondingly, the driving force of the driving motor 92 is transmitted to the force gear 105, and the force gear 105, the shaft 108, and the pushing plate 110 are rotated in the direction opposite to the arrow B direction, As a result, an elastic force is accumulated in the spring 106 that is in contact with the pushing plate 110.

[0078] When the notch 74 corresponds to the bevel gear 105, the force gear 105 and the shaft 108 become free, and the force gear 105 and the shaft 108 are moved via the pushing plate 110 by the restoring force of the spring 106. It will rotate in the direction of arrow B.

[0079] Here, the force pushing plate 110 shown as an example of a power transmission member of the drive motor 92 when the drive motor 92 rotates only in the negative direction is caused to fall down to the drawer 10 side and fall down. However, the present invention is not limited to this because it is only necessary to return the extruded plate 110 to its original position.

[0080] For example, the drive motor 92 may be rotatable forward and backward. In this case, the notch 104A is not formed in the force gear 104 as the second transmission member, and the driving force from the drive motor 92 is always transmitted to the shaft 108.

Then, the shaft 108 is rotated in a direction in which the push-out plate 110 is tilted toward the drawer 10 side by rotation of the drive motor 92 in one direction. At this time, the pushing plate 110 is urged toward the drawer 10 side by the spring 106 to reduce the load on the drive motor 92. As a result, the drive motor 92 can be reduced in size, and the space efficiency of the drive unit 90 is improved. [0082] Then, the shaft 108 is rotated in a direction in which the extruded plate 110 that has fallen by the rotation of the drive motor 92 in the reverse direction is returned to the original position. At this time, the spring 106 is pressed in the direction in which the urging force resists, and an elastic force is accumulated in the spring 106.

Next, the retracting device 111 that retracts the drawer 10 into the case 12 will be described.

[0084] As shown in FIGS. 13A and 13B (FIG. 13A is a plan view showing the retracting device 111, and FIG. 13B is a side view showing the retracting device 111), the side wall 12A of the case 12 includes A mounting pin 112 and an engaging pin 114 are provided along the horizontal direction, and the mounting pin 112 is located in the back of the case 12. One end or the other end of the tension panel 116 is attached to the attachment pin 112 and the engagement pin 114, respectively, so that a biasing force is applied to pull the engagement pin 114 toward the attachment pin 112. /!

In addition, the side wall 12A of the case 12 is provided with a plate 120 in which a guide hole 118 is formed. The guide hole 118 includes a straight portion 118A formed along the horizontal direction, and a standby portion 118B bent downward from the end portion of the straight portion 118A located on the opening side of the case 12. Yes. An engagement pin 114 can be engaged with the guide hole 118.

[0086] On the other hand, on the side wall 10A of the drawer 10, a pair of guide walls 124, 126 formed obliquely so that the back side of the case 12 is lowered with respect to the horizontal direction protrudes, and the engagement pin 114 is provided. Engagement is possible. The guide pins 124 and 126 guide the engaging pin 114 in the guide hole 118.

Specifically, as shown in FIG. 13B, when the drawer 10 is housed in the case 12, the engagement pin 114 is positioned on the other end side of the guide hole 118. In this state, the engaging pin 114 is in contact with the guide wall 124. When the drawer 10 is pulled out from the case 12, the engaging pin 114 is pressed from the guide wall 124 by the movement of the drawer 10, and the straight portion 118A. To the end of At this time, the engaging pin 114 and the mounting pin 112 are gradually separated. For this reason, the pulling panel 116 is stretched and the elastic force is accumulated.

Then, as shown in FIG. 13C, with the engagement pin 114 reaching the standby portion 118B, the engagement pin 114 moves downward along the shape of the standby portion 118B according to the inclination of the guide wall 124. The lower end of the guide wall 124 is positioned above the back wall of the standby part 118B. When the drawer 10 is pulled out by a predetermined length, the engagement pin 114 is released from the contact state with the guide wall 124 in the standby portion 118B.

[0089] In this state, as shown in FIG. 13D, the engaging pin 114 waits in the standby section 118B. For this reason, the separation distance between the engagement pin 114 and the mounting pin 112 remains in this state.

The tension panel 116 is maintained in a state where elastic force is accumulated. At this time, since the urging force of the pull panel 116 does not act on the drawer 10, the drawer 10 is pulled out with a low load (see FIGS. 14A and 14B).

Here, FIGS. 14A, 14C, and 14E are plan views showing the retracting device 111, and FIGS. 14B, 14D, and 14F are the retracting devices 111 corresponding to FIGS. 14A, 14C, and 14E, respectively. FIG.

Next, as shown in FIG. 13C, when the drawn-out drawer 10 is stored in the case 12, the guide wall 126 formed at the lower end side longer than the guide wall 124 contacts the engaging pin 114. (Refer to Fig. 14C and Fig. 14D). When the drawer 10 is further pushed into the back of the case 12 from this state, the engagement pin 114 is guided upward in the standby portion 118B according to the inclination of the guide wall 126.

When the engagement pin 114 reaches the straight portion 118A, the engagement pin 114 moves in the straight portion 118A toward the end of the straight portion 118A by the restoring force of the pull panel 116. At this time, the engaging pin 114 contacts the guide wall 124 and presses the guide wall 124. Then, the drawer 10 is pulled into the back of the case 12 through the guide wall 124, and the drawer 10 is stored in the case 12 (see FIGS. 14E and 14F).

Here, the pulling device 111 for pulling the drawer 10 into the case 12 may be disposed on the side wall 10A of the force disposed on one side wall 10A of the drawer 10. Further, since it is sufficient that the drawer 10 can be pulled into the case 12, the configuration of the pull-in device 111 is not limited to this. In the present invention, the pull-in device 111 is not necessarily provided.

Next, the operation of the drawing device 130 according to the embodiment of the present invention will be described with reference to FIG.

(Extruder) As shown in FIG. 16, when the main switch 132 is turned on in step 100 (main switch ON), the drive unit 90 enters a standby state in step 102 (see FIGS. 12A and 12B). In this state, the drawer 10 can be manually opened and closed. As shown in step 104, the drawer 10 is stored in the case 12 (closed state), and as shown in step 106, the lock switch 134 is opened. Is OFF, the plunger 60 of the solenoid 58 of the lock unit 56 is pulled in by a permanent magnet, and the engagement state between the engagement claw 70 and the lock hole 42 is released (lock release state). It is.

[0095] In this state, as shown in step 108, when the touch panel 16 (OPEN switch) is touched, the drive motor 92 of the drive unit 90 is driven as shown in step 110, and the gear 104 The meshing state of the gear 105 is released, the gear gear 105 and the shaft 108 are in a free state, and the roller 110A provided at the free end of the push plate 110 abuts the rear plate 15 of the drawer 10 In this state, the pushing plate 110 rotates by the urging force of the spring 106 and falls forward. As a result, the drawer 10 is pushed out of the case 12.

As described above, in the present invention, when the touch panel 16 is touched, the drive motor 92 of the drive unit 90 is driven, and the pushing plate 110 is rotated forward by the urging force of the spring 106 and falls forward. The drawer 10 is pushed out of the case 12.

Therefore, the drawer 10 can be easily and quickly pulled out with a low load. Therefore, the drawer operation can be easily performed for a physically handicapped person or an elderly person. Further, since the drawer 10 is pushed out by the forward tilting of the push-out plate 110 (the drawer 10 side), for example, although not shown, the piston is moved in the cylinder using an air cylinder or the like to move the piston tip. As compared with the case where the drawer 10 is pushed out by bringing the drawer 10 into contact with the rear plate 15 of the drawer 10, the thickness in the depth direction of the drive unit 90 can be reduced.

[0098] Here, if the drawer 10 is to be stored in the case 12 in a state in which the push-out plate 110 is tilted forward, in addition to the pressing force for storing the drawer 10, an elastic force is accumulated in the spring 106. A pressing force is required. Therefore, after the drawer 10 is pushed out, the force gear 105 force S bevel gear 104 meshes, the drive force of the drive motor 92 is transmitted to the force gear 105, the shaft 108 is driven, and the spring 106 Rotate the pusher plate 110 in the direction against the urging force, and return the pusher plate 110 that has fallen forward to the original position to the drive mode. The motor 92 stops driving (standby state).

[0099] In step 104, when drawer 10 is closed, as shown in step 112, when lock switch 134 is inserted (lock switch ON), solenoid 58 of lock unit 56 is energized, and the permanent magnet The plunger 60 is pushed out, the engaging claw 70 engages with the lock hole 42 (locked state), and the drawer 10 cannot be opened. Therefore, in this state, as shown in step 114, even if the touch panel 16 (OPEN switch) is touched, the drawer 10 will not be opened. As shown in step 116, an alarm will sound as a warning sound. It rings.

[0100] Further, as shown in step 118, even if the touch panel 16 (OPEN switch) is touched at step 120 with the drawer 10 being pulled out (opened), the drive unit 90 The drive motor 92 is not driven (step 122). That is, the extruded plate 110 does not move.

On the other hand, as shown in step 124, when main switch 132 is OFF, drawer 10 can be manually opened and closed as shown in step 126, but drive unit 90 does not operate.

(Lock unit 56)

As shown in Fig. 17, with step 130 turned on, main switch 132 turned on, drawer 10 closed as shown in step 132, and lock switch 134 turned on as shown in step 134. As shown in Step 136, when an earthquake is detected by the seismic sensor 128, the solenoid 58 constituting the lock unit 56 is energized, the magnetic force of the permanent magnet is canceled, and the plunger 60 is pushed out. The lock plate 72 is locked in the lock hole 42 (step 138).

[0102] Thus, in the present invention, the drawer 10 is not opened (drawn out) without permission by locking the drawer 10 by turning on the lock switch 134 or by an earthquake with the drawer 10 closed. I am doing so. For example, a small child can be prevented from opening the drawer 10 without permission. In addition, in the event of an earthquake, the drawer 10 can be pulled out of the case 12 due to shaking, and the objects in the drawer 10 can be prevented from jumping out. [0103] Then, as shown in step 140, when the lock switch 134 is turned OFF in this state, the solenoid 58 is energized, the magnetic force is restored, the plunger 60 is bowed in, and the lock plate 72 is locked into the lock hole 42. Is unlocked (unlocked; step 142).

[0104] That is, as shown in step 138, even if power supply is disabled due to a power failure or the like as shown in step 144 in the locked state of the lock plate 72 as shown in step 138, as shown in step 146. The lock plate 72 continues to maintain the locked state. Then, as shown in step 148, after the power supply can be supplied due to the restoration of the power failure, etc., as shown in step 150, when the main switch 132 is turned on, the solenoid 58 is energized and the plunger 60 is turned on. When pulled, the lock plate 72 swings and is unlocked (step 152).

[0105] If the power supply cannot be supplied due to a power failure or the like, and you want to release the locked state of the lock plate 72, rotate the cover 30 of the touch panel 16 and remove it from the through hole 32. Insert a screwdriver or the like and press the shaft 64 to swing the lock plate 72. As a result, the lock plate 72 is unlocked (step 154), and the drawer 10 can be manually opened and closed (step 156).

[0106] On the other hand, as shown in step 158, when drawer 10 is opened and lock switch 134 is turned on as shown in step 160, an alarm sounds as shown in step 162. Yes. Even if the drawer 10 is completely closed, there is a case where an object is pinched between the drawer 10 and the case 12 and the drawer 10 is not completely closed. In order to prevent this situation, alarm warnings are provided.

[0107] When an earthquake is detected by the seismic sensor 128 with the drawer 10 opened, as shown in step 164, the solenoid 58 constituting the lock unit 56 is energized and the plunger 60 is pushed out. Thus, the lock plate 72 is engaged with the lock hole 42 and locked (step 166).

However, when the drawer 10 is housed in the case 12 in this state (step 168), the engagement piece 40 comes into contact with the distal end surface of the engagement claw 70, and thereby the lock plate 72 swings. . That is, the lock plate 72 can also retract the lock position force, and the lock hole 42 of the engagement piece 40 is engaged. When the pawl 70 is reached, the engaging pawl 70 is engaged with the lock hole 42 by the urging force of the torsion panel 62, and the lock plate 72 is locked (step 170). For this reason, the drawer 10 cannot be opened or closed.

In this embodiment, as shown in FIG. 4, a plate-like touch panel 16 is provided in parallel with the front plate 14 of the drawer 10, but as shown in FIG. 18, a flange 138 is provided on the upper surface. The holding member 142 having the attachment surface 140 formed obliquely downward from the front end of the flange 138 may be attached to the front plate 14 of the drawer 10, and the touch panel 16 may be attached to the attachment surface 140.

That is, the touch panel 16 is directed obliquely downward so that the touch panel 16 cannot be touched unless there is an intention to touch the touch panel 16. This prevents malfunction of the touch panel 16. In addition, the collar 138 can prevent water droplets from adhering to the surface of the touch panel 16.

In addition to this, as shown in FIG. 19, a hook-shaped gripping portion 144 is provided at the upper end portion of the front plate 14 of the drawer 10, and the tip end portion of the gripping portion 144 is curved in a bowl shape. The arc portion 144A may be provided, and the touch panel 16 may be provided on the back surface of the arc portion 144A. In this case, since the touch panel 16 is not exposed on the surface, there is no fear of energization due to contact with clothes and the like, and malfunction is prevented.

Furthermore, as shown in FIGS. 20A and 20B, a notch 14A is provided in the front plate 14 of the drawer 10, and a guard cover 146 including the notch 14A and parallel to the front plate 14 is provided on the front plate 14. A touch panel 16 may be provided at a position facing the guard cover 146 so as to guard the touch panel 16.

In this embodiment, the touch panel 16 is composed of a touch plate 18 and a GND plate 20, and a force that detects a difference in capacitance with 0 V (GND) as a reference. As shown in FIG. It is also possible to detect a change in capacitance caused by contacting the touch panel 16 with the energization detection device 50. In this case, the gripping part 144 itself is made of a metal such as aluminum, and the gripping part 144 itself changes to a GND plate so that when the touch plate 18 is touched, the gripping part 144 is always touched. The touch plate 18 is arranged as follows.

[0114] Further, in this embodiment, the push plate 110 fixed to the shaft 108 is rotated around the shaft 108 along the horizontal plane by the biasing force of the spring 106, and the front plate 108 is moved forward. Because the pushing plate 110 can be pulled down by pulling it toward the 10 side, the pusher plate 110 is rotated along the vertical plane by changing the position of the shaft 108 so that it falls forward. Anyway, okay.

[0115] Instead of the extruded plate 110, as shown in FIG. 21, a ball screw 150 and a pair of link members 152, 154 may be used. In this case, the ball screw 150 is disposed in parallel with the rear plate 15 of the drawer 10 and a driving force from the motor 156 is transmitted to the ball screw 150 using a motor 156 that can rotate forward and backward. The ball screw 150 is screwed symmetrically, and a pair of nuts 158 and 160 are screwed to the left and right, and are brought into and out of contact with each other by forward and reverse rotation of the motor 156.

[0116] Further, one ends of link members 152 and 154 are connected to the nuts 158 and 160, respectively, and the other end of the link member 152 and the other end of the link member 154 are connected to each other. As a result, the position of the top 162 of the link members 152, 154 can be changed according to the distance between the nuts 158, 160. That is, the amount of protrusion of the top 162 of the link members 152, 154 toward the drawer 10 side (in the direction of arrow C) can be changed, and the drawer 10 can be pushed out from the case 12.

[0117] Here, a force in which a pair of nuts 158 and 160 are screwed into the left and right of the ball screw 150, and one end portions of the link members 152 and 154 are connected to the nuts 158 and 160, respectively, as shown in FIG. Only the nut 160 may be screwed into the ball screw 150, and the link member 152 may be pivotally supported by the shaft support 161 on the link member 152 side. Accordingly, the position of the top 162 of the link members 152 and 154 can be changed depending on the position of the nut 160.

Further, as shown in FIG. 23, the other end of the link member 152 and the other end of the link member 154 are not directly connected to each other, but the center portion of the link member 164 and the center portion of the link member 168 are rotated together. Connect to be movable.

Then, one end portion of the link member 164 is connected to the other end portion of the link member 152, and one end portion of the link member 168 is connected to the other end portion of the link member 154, so that the other end of the link member 164 is connected. And the other end of the link member 168 are connected (so-called pantograph type). In this case, the forward protrusion amount of the top portions 170 of the link members 152 and 154 with respect to the movement amount of the nut can be increased as compared with the case of FIG. Further, as shown in FIG. 24, a link member 172 is pivotally supported so that the link member 174 can move along a guide surface 176 provided in parallel with the rear plate 15 of the drawer 10. . A slide pin 182 is provided at the center of the link member 174, and a long hole 184 in which the slide pin 182 can slide along the longitudinal direction of the link member 172 is provided at the center of the link member 172. Further, the plunger 180 of the air cylinder 178 is fixed to the link member 174, and the link member 174 changes the inclination angle by moving the plunger 180 in and out, and moves on the guide surface 176. Due to the movement of the link member 174, the slide pin 182 slides in the long hole 184, whereby the amount of fall of the link members 172, 174 can be changed.

[0121] As described above, this embodiment is applicable to any drawer for reducing the force and load described for the drawer device 130 of the system kitchen. For this reason, for example, it may be used for a drawer for nursing care or a drawer for infants.

Industrial applicability

[0122] The present invention can be widely applied to a general drawing apparatus including a drawer that is housed in a case provided with an opening and that can be inserted into and removed from the opening. Since the drawer can be pulled out only by applying a low load, it may be used for, for example, a drawer for nursing care and a drawer for infants in addition to the drawer device of the system kitchen.
