FIG. 1 is a perspective view showing the appearance of the combination cabinet of the present invention. As can be seen from this figure, this combined cabinet 10 includes a drawer cabinet 20 having three (upper, middle and lower) drawers 22a, 22b and 22c located on the lower side in contact with the floor, and an upper part of the drawer cabinet. It is comprised from the door cabinet 50 provided with the opening-and-closing door 52 mounted on. The combined cabinet 10 is a so-called steel furniture manufactured mainly using a thin metal plate material.
The drawer cabinet 20 has a rectangular parallelepiped shape with a width × depth × height of 90 cm × 60 cm × 120 cm and a front opening, and three drawers each having a width × depth × height of 85 cm × 52 cm × 36 cm. 22a, 22b, and 22c. Each drawer can be smoothly pulled out and stored by a rail and a roller (not shown) provided on the inner side surface of the casing.
The door cabinet 50 has a rectangular parallelepiped shape with a width × depth × height of 90 cm × 60 cm × 80 cm, and a double door opening / closing door 52 is provided in front of the door cabinet 50. A shelf is attached to the interior of the door cabinet 50 so as to partition the internal space (not shown).
The structure of the combined cabinet 10 is not particularly different from the conventional cabinet with respect to the parts other than the lock mechanism described below, and the description of the general structure is omitted.

The drawer cabinet 20 is provided with a first lock mechanism that prohibits the withdrawal of the other drawers 22b, 22c / 22a, 22c / 22a, 22b when one drawer 22a / 22b / 22c is pulled out. The first locking mechanism is provided for each drawer on the back side of the drawer cabinet 20.
2 and 3 are conceptual diagrams for explaining the mechanism of the first lock mechanism, and FIGS. 2A and 2B are internal see-through side views for explaining the first lock mechanism and its operation. FIG. (A) (b) is an internal permeation | transmission front view corresponding to FIG. 2 (a) (b). In FIG. 3, the taper surface of the first lock mechanism is omitted, and the main rod and the like are shown in a side view for easy understanding.

  As shown in these drawings, the first locking mechanism 24 includes a tapered surface 26 formed to be inclined on the back surface of each of the hook-shaped drawers 22a, 22b, and 22c, and a locking portion formed on the back surface of each drawer. 28 and one corresponding drawer 22a / 22b / 22c are retracted, one end is pushed down by contact with the tapered surface 26, while one drawer is pulled out, one end is opened and the other is A rotating arm 32 that rotates like a falling seesaw, and is connected to the other end of the rotating arm and moves up and down as the rotating arm rotates, and the other drawers 22b, 22c / 22a, 22c / 22a, 22b. It has a main rod 36 that extends in the vertical direction and has a hook portion 34 that engages with the locking portion 28 on the back surface.

More specifically, the tapered surface 26 of each of the drawers 22a, 22b, and 22c is inclined such that the upper side protrudes horizontally about 4 cm rearward from the rear face of the drawer and gradually decreases as the distance decreases downward. The tapered surface 26 is formed over the entire width of the drawers 22a, 22b, and 22c.
The locking portion 28 is formed so as to protrude about 1 cm from the upper side of the tapered surface 26 toward the upper side.

  The rotation arm 32 provided in the drawer cabinet 20 housing corresponding to each drawer 22a, 22b, 22c is a bar having a length of about 6 cm provided on the back side (back side) of the inner surface of the housing. With the intermediate portion as a fulcrum, its end can move up and down like a seesaw within a rotation range of ± 1.5 cm. One end of the rotating arm 32 extends toward the front side of the cabinet and the other end extends toward the back side. A rotating roller 33 is provided at one end of the rotating arm 32, and this rotating roller comes into contact with the tapered surface 26 on the back surface of the drawer. On the other hand, the other end of the rotating arm 32 is rotatably connected to the main rod 36.

The main rod 36 provided in the case of the drawer cabinet 20 corresponding to each drawer 22a, 22b, 22c is a bar having a length of about 110 cm provided to extend in the vertical direction on the back surface of the inner surface of the case. The main rod 36 corresponding to the upper drawer 22a is connected to a rotating arm 32 that rotates as the upper drawer is pulled in and out, and is formed on the back surface of the drawer at a position corresponding to the middle and lower drawers 22b and 22c. A hook-shaped hook portion 34 that is bent downward is formed so as to be engaged with the engaging portion 28 formed. Further, the main rod 36 corresponding to the middle drawer 22b is connected to a rotating arm 32 that rotates as the middle drawer is pulled in and out, and the position corresponding to the upper and lower drawers 22a and 22c is on the back surface of the drawer. A hook-like hook portion 34 that is bent downward to be engaged with the formed locking portion 28 is formed. The same applies to the main rod 36 corresponding to the lower drawer 22c.
A first spring 37 that biases the main rod downward is attached to the lower ends of the three main rods 36.

That is, for example, in a state where the upper drawer 22a is stored, the rotating roller 33 at one end of the rotating arm 32 connected to the corresponding main rod 36 is pushed down by contact with the tapered surface 26 on the rear face of the drawer 22a. As a result, the other end of the rotating arm 32 is raised, and the main rod 36 connected thereto is pushed upward. At this time, the first spring 37 attached to the main rod 36 is in a compressed state, and urges the main rod 36 downward. In this state, the engaging portions 28 of the middle and lower drawers 22b and 22c and the hook portion 34 of the main rod 36 are not engaged.
On the other hand, when the upper drawer 22a is pulled out, the taper surface 26 that pushed down the rotating arm 32 disappears and the rotating arm is released, so that the main rod 36 is pushed down by the biasing force of the attached first spring 37. . When the main rod 36 is pushed down, the locking portions 28 of the middle and lower drawers 22b and 22c engage with the hook portions 34 of the main rod 36, and the middle drawer is not allowed to be pulled out.
In the state in which the middle drawers 22b and 22c are stored, the corresponding main lot is pushed up, and the engaging portions 28 of the upper and lower drawers 22a and 22c are not engaged with the hook portions 34 of the main rod 36. When the middle drawer 22 b is pulled out, the main rod 36 is pushed down by the biasing force of the first spring 37. When the main rod 36 is pushed down, the engaging portions 28 of the upper and lower drawers 22a and 22c engage with the hook portions 34 of the main rod 36, and the upper and lower drawers are prohibited from being pulled out.
In the state where the lower drawer 22c is housed, the corresponding main lot is pushed up, and the locking portion 28 of the upper middle drawers 22a and 22b and the hook portion 34 of the main rod 36 are not engaged. When the drawer 22c is pulled out, the main rod 36 is pushed down by the biasing force of the first spring 37. When the main rod 36 is pushed down, the engaging portions 28 of the upper and middle drawers 22a and 22b and the hook portions 34 of the main rod 36 are engaged, and the upper and middle drawers are prevented from being pulled out.

As described above, the three first lock mechanisms 24 cooperate to pull out the other drawers 22b, 22c / 22a, 22c / 22a, and 22b when any one of the drawers 22a / 22b / 22c is pulled out. I can't do that.
In the above description, the drawer has three stages, upper, middle, and lower. However, the present invention is not limited to this, and the number of drawers can be two or four or more. .

Further, an inverted U-shaped hook 39 for hooking a connecting member 41 for connecting to the second lock mechanism 54 described below is formed at the upper end of each main rod 36 of the first lock mechanism 24. Yes. When any one main rod 36 is pushed down, the connecting member 41 is pushed down together with it, and is composed of a horizontal bar 41a extending in the width direction on the back of the cabinet housing and a vertical bar 41b extending in the vertical direction from the center. T-shaped. A latch hook 39 of each main rod 36 is latched so as to cover the horizontal bar 41a of the connecting member 41 from above. As a result, when any one of the main rods 36 is pushed down, the connecting member 41 is pushed down at the same time, while the other main rods are not particularly affected by external force because the latching hooks are separated from the connecting member horizontal bar 41a. .
The vertical bar 41b of the connecting member 41 does not protrude from the top surface of the drawer cabinet 20 casing even when it is moved up and down, but can be accessed from the outside so that it can be connected to the second lock mechanism 54 described below. It has become.

FIG. 4 is a conceptual diagram for explaining the second locking mechanism and its operation. In this figure, the second lock mechanism portion is shown as lying side-by-side for easy understanding.
The second locking mechanism 54 of the door cabinet 50 is a slave rod extending in the vertical direction connected to each main rod 36 (actually the vertical bar 41b of the connecting member 41) of the first locking mechanism 24 of the drawer cabinet 20 described above. 56 and a door lock arm 58 linked to the slave rod.

  The sub rod 56 is a bar having a length of about 70 cm, which extends in the vertical direction on the rear surface of the inner surface of the door cabinet 50. After the door cabinet is placed on the drawer cabinet 20, the lower end of the sub rod 56 is the first. It is connected to the upper end of the vertical bar 41 b of the connecting member 41 of the one lock mechanism 24. The slave rod 56 is attached with a second spring 61 that urges the slave rod upward. That is, the slave rod 56 moves up and down together with the vertical movement of the vertical bar 41b of the connecting member 41. In addition, in order to connect the sub rod 56 with the vertical bar 41 b of the connecting member 41, a through hole (not shown) is formed on the bottom surface of the door cabinet 50.

One end of the door lock arm 58 is connected to the upper end of the slave rod 56, and the other end is an articulated bar that functions as an engaging protrusion for locking the open / close door 52. The parts are connected in a pivotable manner.
As shown in the figure, the first member 58a, the lower end of which is connected to the upper end of the follower rod 56, is pivotally attached to the inner side of the rear surface of the door cabinet 50 with its middle portion serving as a fulcrum. When the slave rod 56 is pulled downward, the first member 58a rotates so as to change from an inclined state to a substantially vertical state. The upper end of the first member 58a is connected to the rear end of the second member 58b extending from the back side of the door cabinet 50 to the door side inside the top surface of the door cabinet 50. The second member 58b moves back and forth in the axial direction as the first member 58a rotates. Further, the front end of the second member 58b is connected and connected to the upper end of the rotatable third member 58c with the middle portion as a fulcrum. When the second member 58b slides forward, the third member 58c rotates so as to change from an inclined state to a substantially vertical state. A fourth member 58d, which prohibits / allows (locks / opens) the opening / closing of the door 52 as the third member 58c rotates, is connected to the lower end of the third member 58c. When the third member 58c is rotated from the tilted state to the substantially vertical state, the lower end of the fourth member 58d protrudes from the door frame on the front surface of the door cabinet 50 and is respectively placed on the upper edge portions of the left and right open / close doors 52. Each open / close door is locked by being inserted into the provided small hole 65. That is, the door lock arm 58 transmits the vertical movement of the slave rod 56 connected thereto to the vertical movement of the fourth member 58d to prohibit / allow the opening / closing of the open / close door 52.

  Thus, the second lock mechanism 54 connected to each main rod 36 of the first lock mechanism 24 (more precisely, the vertical bar 41b of the connecting member 41) has one of the drawers 22a / 22b / 22c of the drawer cabinet 20. When the vertical rod 41b of the first lock mechanism is pulled down by being pulled out, the slave rod 56 is also pulled down accordingly (the second spring 61 is compressed at this time) so that the first member 58a is in a vertical state. The second member 58b is slid to the front side of the cabinet, the third member 58c is rotated so as to be in a vertical state, the fourth member 58d is pushed down, and the lower end thereof is located on the front surface of the housing of the door cabinet 50. Projecting from the door frame, this is a mechanism for locking the open / close door 52. Since the door of this door cabinet is of a type in which the left door cannot be opened unless the right door is opened, only the right door is locked.

  Here, each first lock mechanism 24 (vertical bar 41b of the connecting member 41) of the drawer cabinet 20 and the second lock mechanism 54 (secondary rod 56) of the door cabinet 50 are placed after the door cabinet is placed on the drawer cabinet. The connection is connected using a connection adapter.

FIG. 5 shows a state in which the first lock mechanism (the connecting material vertical bar 41b) and the second lock mechanism (the slave rod 56) are connected and connected using the connection adapter.
This connection adapter 82 is a long nut having a length of about 15 cm in which a normal screw hole is dug in one end and a reverse screw hole is dug in the other end. In order to connect and connect the vertical bar 41b of the connecting member 41 and the slave rod 56 using the connection adapter 82, the front end of the vertical bar 41b is cut with a normal screw and a reverse screw at the lower end of the slave rod. ing.
The connection between the vertical bar 41b and the slave rod 56 by the connecting adapter 82 is performed when the door cabinet 50 is placed on the drawer cabinet 20 and then the drawers 22a, 22b and 22c of the drawer cabinet 20 are stored. Open the open / close door 52, insert the connection adapter 82 from the through hole on the bottom side of the bottom of the door cabinet housing toward the vertical bar 41b, rotate it forward about one rotation, and lightly screw the positive screw hole at one end (lower side). Thereafter, the reverse screw hole at the other end (upper end) of the connection adapter is also screwed into the slave rod 56 and screwed in sufficiently.

As described above, according to the combined cabinet of the present invention described above, since the drawers of the drawer cabinet cannot be pulled out at the same time, the danger of the cabinet falling can be avoided, and at the same time, the drawer is pulled out. Opening the door cabinet door is prohibited, so when a person who was working with the drawer bent inadvertently stood up, put the head etc. on the door cabinet door that was open without thinking. Accidents can be prevented.
Since the connection connection between the first lock mechanism of the drawer cabinet and the second lock mechanism of the door cabinet is performed using the connection adapter, the combined cabinet can be easily disassembled and transported.

  FIG. 6 is a diagram for explaining a third locking mechanism and the like that can be further added to the combined cabinet including the first locking mechanism and the second locking mechanism. The purpose of this third locking mechanism is to prevent the occurrence of accidents more reliably by preventing the drawer of the lower drawer cabinet from being pulled out when the upper door cabinet is opened. .

  As described above, the present invention is a combination of a drawer cabinet 20 having one or more drawers (three drawers 22a, 22b, 22c in the drawing) and a door cabinet 50 having an open / close door 52 placed thereon. Since the present invention is applied to the combined cabinet 10, the same reference numerals are given to the drawings for the basic structure of the cabinet, and the description overlapping with the above description is omitted.

The drawer cabinet 20 is provided with a third lock mechanism 84 that prohibits all drawers from being pulled out when the open / close door 52 of the door cabinet 50 is opened. An interlocking arm 94 for operating the three-lock mechanism is provided.
The upper end of the third lock mechanism 84 and the lower end of the interlocking arm 94 are connected, and the connection is performed by the same method using the connection adapter 82.
