Conventional units are usually pulled out one by one. However, when a plurality of units are pulled out simultaneously by mistake, the center of gravity is shifted to the front of the cabinet body due to the weight of the units.
Therefore, the cabinet body has a problem that the falling angle cannot be satisfied.

[0005] Therefore, since the cabinet is tilted forward, there is a problem that the object placed on the cabinet falls, breaks, or soils the floor.

It has also been proposed that the components of the slide member and the guide member are directly locked so that a plurality of units cannot be simultaneously withdrawn by mistake. However, if the slide member or the guide member in the locked state is forcibly pulled out, the slide member or the guide member may be damaged due to scratches or the like.

Further, when the components of the slide member are directly locked, other units cannot be pulled out. Even if it is desired to pull out another unit with a small amount of pulling out, at the same time, the other unit is slightly pulled out. There is a problem that it is not possible to perform the work of drawing out with the amount of drawing out.

Therefore, the unit drawer according to the present invention provides a unit drawer capable of limiting the number of units that can be pulled out by a simple mechanism in order to satisfy the falling angle when the weight of the unit is heavy. It is in.

Another object of the present invention is to provide a unit drawer that can draw out even when the power of the apparatus is turned off because no electric power is used.

Another object of the present invention is to provide a unit pull-out device which does not damage the slide member and the guide member.

Still another object of the present invention is to provide a unit pull-out device capable of pulling out the slide member in a stable state by a correct posture even if the amount of pull-out of the slide member is larger than the length of the slide member. Is to do.

And a plurality of guide members which are slidably fitted in the first and second directions in a one-to-one manner, wherein the slide member is fixed between the units and provided on each of the side surfaces of the units. First and second mounting members,
A fixed bracket member positioned between the first and second mounting members to fix the guide member and fixed to the cabinet body, and further comprising the first and second mounting members together with one of the units. When one of the members is pulled out in the first direction, the member has a pull-out restricting mechanism that restricts the pull-out of the other unit, and the pull-out restricting mechanism is provided for each of the first and second mounting members. The mounting restriction plate portion formed in the above, and by being pressed against one of the mounting restriction plate portions and turning to face the other of the mounting restriction plate portions, the drawer of the other unit is restricted. A unit pull-out device characterized in that the fixed bracket member has a regulating plate member rotatably supported on the fixed bracket member.

[0013]

In the unit pull-out device according to the present invention, when the unit is pulled out from the cabinet body, the first mounting member is pulled out in the first direction. When the first mounting member is slightly pulled out from the opening, one of the restriction plate portions of the restriction plate member is turned in the rotation direction by the member pressed by the end of the notch. Thereafter, the one regulating plate portion is in a state of being pushed along the mounting side plate portion. Thus, the other regulating plate prevents the notch in the other mounting regulating plate from moving.
The other regulating plate portion obstructs the movable area of the mounting member, and prevents sliding. Therefore, the other unit is regulated by the pull-out regulating mechanism so that it cannot be pulled out.

Further, the locking piece and the mating locking piece of the extension bracket come into contact with each other to lock each other, and the extension bracket is pulled out. Thereby, the drawer function is continued without the unit coming off the cabinet body.

Thus, the one restriction plate portion 55a of the restriction plate member 56 pivotally supported by the shaft 55 prevents the movement of the first cutout portion 23g in the first attachment restriction plate portion 23c, thereby causing the first notch portion 23g to move. One of the restricting plate portions 55a obstructs the movable area of the mounting member 23 and prevents sliding. Therefore, the first unit 13 is moved by the pull-out restricting mechanism to the first unit 13.
Is restricted so that the unit 13 cannot be pulled out.

Further, if the second unit 14 is pulled out beyond the length of the second inner slide member 35, the second locking piece 6 of the second extension bracket 63
3a and the second mating locking piece 33f of the second mounting member 33 abut against each other, and the second extension bracket 63 is pulled out. Thereby, the draw-out function is continued without the second unit 14 coming off the cabinet body 12.

FIG. 5 shows a second embodiment of the unit drawer of the present invention. The unit pull-out device according to the second embodiment differs from the first embodiment only in the configuration of a part of the first mounting member 23. Therefore, the same parts are denoted by the same reference numerals. The description is omitted.

Referring to FIG. 5, in first mounting member 23, first mounting regulating plate 23c is added from the end of first notch 23g at the front end on the front direction I side to the rear direction II side. A notch 23j is formed. That is, the first attachment regulating plate 23c has a shape from the front end on the side in the rear direction II to halfway in the front direction I.

In this embodiment, the first unit 1
While the extension 3 is being pulled out halfway, one regulation plate portion 55a of the regulation plate member 56 pivotally supported by the shaft 55 moves to the end of the first cutout portion 23g in the first mounting regulation plate portion 23c. Is prevented, and the movable area of the first mounting member 23 is not obstructed by the one regulating plate portion 55a.

Therefore, the forward direction I portion of the additional notch portion 23j becomes the escape portion of one of the restriction plate portions 55a, so that the second unit 14 can be pulled out a little, and the second unit 14 can be completely removed. Nothing can't be withdrawn.

Therefore, for example, when the first unit 13 is being pulled out, the second unit 14 can be pulled out with the additional notch 23j being restricted.

In the first and second embodiments, 2
The cabinet 11 accommodating the first and second units 13 and 14 has been described.
Needless to say, the present invention can be applied to a case in which two or more units are housed and pulled out within 2.
