As shown in FIGS. 3A and 3B, on the side surface of the shelf 1, an illumination lamp 6 is provided near the upper portion of the table 4 and an illumination lamp 6a is provided near the upper portion of the table 4a.
Is provided. The illuminating lights 6 and 6a illuminate the upper surfaces of the tables 4 and 4a in the advance mode.

It is more preferable to provide a display means for displaying the table when the table is in the advance mode. The display means may be an optical display using a display lamp, a light emitting diode, a liquid crystal display element, or the like, as well as a sound display such as a bell, a buzzer, music, or a special sound effect. Also, for people who are deaf or blind, they may be displayed by vibration, or a heating element or a cooling element may be provided at a predetermined site to display the change in temperature. It may be displayed by changes in wind and odor. Furthermore, a special sound may be emitted so that it can be recognized only through a special earphone.

Next, a concrete example of the table 4 will be described. 4 to 6, the shelf 1 has columns 7 on the front side, the back side, and the central portion when viewed from the front side (right side and left side in FIG. 4). The other columns, which are not shown, corresponding to the above, constitute the frame of the shelf 1. A side panel 3a forming the side surface 3 is fixed to the outer surface of each of the columns 7. A concave portion 8 is formed at an appropriate height position of the side panel 3a, and one end portion of the table 4 is connected to a lower end outer portion of the concave portion 8 by a hinge 12, so that the table 4 moves up and down about the axis of the hinge 12. It is provided so that it can rotate in any direction. When viewed from the side of the shelf 1, two levers 16 and 1 are provided on the left and right sides of the table 4, respectively.
A support member 15 made of 7 is provided. Support member 1
The two levers 16 and 17 that form part 5 are rotatably connected to each other by a shaft 19, and one end of the lever 16 has a shaft 18
Is rotatably connected to the side panel 3a in a vertical plane, and one end of the lever 17 is rotatably connected to the table 4 by a shaft 20 in a vertical plane. Two levers 1
Reference numerals 6 and 17 have contact portions 21 that abut each other. The table 4 is rotated to advance from the side surface 3 of the shelf 1 in a direction perpendicular to the contact portions 21 so that the table 4 can be advanced. It is designed to hold.

A magnet latch 9 for attracting an iron plate or the like on the surface of the table 4 by magnetic force is attached to the upper end of the recessed portion 8, and the magnet latch is stored in the recessed portion 8 by rotating the table 4. The table 9 holds the table 4 by sucking the table 4. A well-known one can be used as the magnet latch 9. For example, when the table 4 in the storage mode and attracted by the magnet latch 9 is pushed from the outside and quickly released, the table 4 is pushed out by the spring force built in the magnet latch 9 and the inertial force of the table 4 is applied to the magnet. It is possible to use a device in which the magnetic attraction force of the latch 9 is overcome and the suction of the table 4 is released. A switch 10 is also provided in the recess 8. The switch 10 is, for example, as shown in FIG.
The switches of the illuminating lamps 6 and 6a shown in FIG. 2 can be operated to turn on and off the illuminating lamps 6 and 6a when the table 4 is in the advance mode. Instead of the magnet latch 9, the table 4 may be held in the accommodated state by a so-called spring catch in which the protrusion is sandwiched by the force of a spring, or a locking lever or other known appropriate means may be adopted. . Further, the table 4 may be located on the same plane as the side surface 3 of the shelf 1 in the storage mode, may slightly protrude from the side surface 3, and may be recessed from the side surface 3.

According to the embodiment described above, the table 4
If the table 4 is made to extend from the side surface 3 of the shelf 1, the table 4 can be used as a shelf on which books and other articles are temporarily placed or as an office desk, and when books and other articles are taken in and out of the shelf 1. It is convenient as an auxiliary table. Since the table 4 is provided on the side surface 3 of the shelf 1, it does not hinder walking in the work passage between the shelves 1 whose front surfaces face each other. When the table 4 is not used, it can be stored in the side surface 3 of the shelf 1, and the table 4 does not protrude from the shelf 1 and hinders the work of taking in and taking out articles. Further, since the table 4 is provided on the side surface 3 of the shelf 1, it can be seen at a glance from outside the shelf device whether the table 4 is in the advance mode or the storage mode. Therefore, when the table 4 is in the advance mode, it is presumed that the article is in and out, and it is possible to prevent the operator from being locked in the room by refraining from locking the doorway to the room. In this case, the safety of workers can be secured by refraining from moving the shelves. If a display means for displaying the table 4 when it is in the advance mode is provided, it is more effective in preventing the operator from being trapped.

In the above embodiment, when the rack 1 is an electric mobile rack, the switch 10 may also be used as an interlock switch. Interlock circuits are already well known in motorized mobile shelves and include switch 10
When is operated, the shelf 1 is constrained to be immovable in a circuit even if an operation for moving the shelf 1 is performed unless the operation is released. The interlock circuit may be one that collectively holds all the electric movable shelves in an unmovable manner by operating the switch 10.
At least the shelf to which the table 4 has advanced, or the shelf to which the table 4 has advanced and the shelf opposite thereto may be restrained immovably, or an arbitrary shelf may be restrained. May be.

If such an interlock circuit is provided, the shelves 1 cannot be moved unless the interlock is released. Therefore, the shelves 1 enter the working passage formed between the shelves 1 to store the articles. If the interlock circuit is activated during the loading / unloading work, the shelf 1 will not be moved by another worker's moving operation, and the safety of the worker during the loading / unloading work can be secured.

FIG. 7 shows a specific example of the illumination lamp 6. Figure 7
In addition, a fluorescent lamp lighting fixture main body 23 is fixed to the side surface 3 of the shelf, and a cover 24 also serving as a reflector is provided on the upper surface of the lighting lamp fixture main body 23 by an appropriate fixing means such as a double-sided adhesive tape 25. It is fixed. In the example of FIG. 7, the illuminating lamp 6 is attached so as to project from the side surface 3 of the shelf. For example, in the example shown in FIG. 6, the upper portion of the recessed portion 8 for accommodating the table 4 or the upper side thereof. You may install in the panel 3a. The illumination lamp may be an appropriate one other than the fluorescent lamp, for example, an incandescent lamp.

8 to 11 show another example of the advance / retreat mechanism of the table 4. 8 to 11, the table 4 is provided at the lower end of the recessed portion 8 formed in the side panel 3a of the shelf so as to be vertically rotatable by the hinge 12 as in the above-described embodiment. The recessed portion 8 has guide bars 28 of a pair of support members 27 on the left and right sides as viewed from the side of the shelf.
Is fixed vertically. Each support member 27 is of a friction type and has a slider 29 that slides along the guide rod 28 with a constant frictional force. One end of an arm 30 is rotatably connected to the slider 29 by a shaft 31, and the other end of the arm 30 is rotatably connected to the table 4 by a shaft 32. When the table 4 is rotated in the vertical direction around the hinge 12, the slider 29 moves up and down along the guide rod 28 via the arm 30. The sliding range of the slider 29 is limited, and when the slider 29 is at the lower limit position of the guide rod 28 as shown in FIG.
In the mode in which the table 4 is housed in the recessed portion 8, the slider 2
9 is near the upper limit of the guide rod 28. Since there is a constant frictional force between the guide rod 28 and the slider 29 as described above, the rotation of the table 4 is performed slowly, and a large impact is not applied even when the table 4 reaches the rotation limit position. .

The recess 8 is provided with the switch 10 and the magnet latch 9 of the illuminating lamp 6 as in the above embodiment.
Further, a detection switch 34 for detecting whether the table 4 is in the advance mode or the storage mode is provided. In this embodiment, the table 4 is made of a non-magnetic material such as wood, and the magnetic latch 36 is attached to the tip of the table 4 to hold the table 4 in a stored state by magnetic force. The detection switch 34 is operated by pushing the actuator when the table 4 is stored in the recessed portion 8, and detects that the table 4 is in the storage mode. Further, when the table 4 is rotated toward the advance mode, the table 4 is separated from the actuator and the switch 34 is reversed to detect that the table 4 is in the advance mode.
When the rack is an electric mobile rack, the switch 34 can be used as the switch for the interlock. That is, the switch 34 indicates that the table 4 is in the advance mode.
When the switch 34 detects that the table 4 is in the storage mode, the interlock is released when the switch 34 detects that the table 4 is in the storage mode. The detection switch 34 may be a switch for the illumination lamp 6 instead of the switch 10, or may be used as both an interlock switch and a switch for the illumination lamp 6. By doing so, the illumination lamp 6 can be turned on in association with the table 4 being in the advance mode.

As the mechanism for rotatably supporting the table 4 so as to be able to take the advancing mode and the accommodating mode, various well-known mechanisms other than the specific examples described above may be appropriately selected and applied. For example, as used in various vehicles and airplanes, the table surface is moved forward and backward with the table surface vertical, and in the advanced state, it is rotated about a horizontal axis to be in a horizontal position. There is a support member on the lower side, which makes the table horizontally advance. Further, the table may be one that hangs down from the spindle in the stored state and rotates in the upward direction from the bottom to take the advanced state. The table 4 does not necessarily have to be in a horizontal position in the advance mode, and when the table 4 is used for office work, FIG.
Further, as shown by a chain line 4A, the tip end side of the table 4 may be inclined so as to be lower than the horizontal position. This will improve usability for office work. In this case, table 4
It is convenient to provide a jetty 4b that prevents documents and the like from slipping off at the tip edge of the. The table 4 may be tilted so that its tip end side is higher than the horizontal position.

The table is not limited to the rotary type, but may be a pull-out type as shown in FIG. 12
In one of the plurality of shelf boards 38 mounted on the shelf 1, a table 40 is fitted in one shelf board 38 mounted at an appropriate height position so that the shelf board 38 can be moved forward and backward in the horizontal direction. Has been. The table 40 can move forward and backward through the side panel 3a of the shelf 1. A handle 40a is attached to the tip of the table 40.
By grasping a and pulling it out, the table 40 can be in a state of advancing from the side surface 3 of the shelf 1 as shown by a chain line 40A, and by grasping and pushing in the handle 40a, the table 40 can be stored in the shelf 1. Can be taken.

The example shown in FIG. 12 also has the same effects as the above-described embodiment. Further, since the table 40 moves forward and backward within the shelf plate 38 using the shelf plate 38 as a guide, the provision of the table 40 does not reduce the original article storage space of the shelf 1 at all. A switch for detecting the advancement state or the storage aspect of the table 40 is provided, and when the table 40 is in the advancement aspect, the interlock circuit described above is operated in conjunction with the detection operation of the switch or the illumination lamp is turned on. You may. The handle 40a does not necessarily have to be attached, and the table 40 may be directly pulled out or pushed. Since a space is usually formed under the shelf plate 38 with the articles placed on the lower shelf plate, the table 40 is configured to move forward and backward in the space under the shelf plate 38. May be.

The shelf to which the present invention is applied may be a handle operation type movable shelf as described below. 13 to 15, the shelf 1 has traveling wheels 51 rotatably supported on the bottom thereof, and the traveling wheels 51 roll on the rails 2 to become traveling shelves. A concave portion 8 is formed on a side surface 3 of the shelf 1, and a table 4 is provided which can be in a storage mode for closing the concave portion 8 and an advancing mode in which the concave portion 8 is opened and protrudes from the side surface 3 at a right angle. There is. A rotary operation handle 41 is pivotally supported on the side surface 3 above the recess 8. Handle 4
1 is provided integrally with the shaft 42. The shaft 42 penetrates the side panel 3 a and a frame body 55 fixed to the inner surface side thereof, and is rotatably supported by a pair of bearings 54 attached to the frame body 55. The shaft 42 includes a sprocket-shaped locked member 52 and a sprocket 4 in a frame 55.
3 are integrally provided.

Below the sprocket 43, a sprocket 46 having a diameter larger than that of the sprocket 43 is provided by a shaft 45.
