Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention moves a plurality of parallel-arranged shelves along the arrangement direction, thereby creating a working path at a desired position between the shelves. The present invention relates to a movable shelf device configured to form a movable shelf device.

(Prior art and its problems) Among conventional shelving devices, there is a movable shelving device in which a plurality of shelves are configured to be movable, respectively, in order to effectively utilize space. This movable shelf device appropriately moves shelves arranged in parallel along the arrangement direction to form a working passage at a desired position between the shelves only when necessary.

Typically, in such a movable shelf device, a lighting fixture is attached to the entire ceiling surface to illuminate the entire device.

However, in this configuration where lighting fixtures are installed over the entire ceiling surface to illuminate the entire equipment, the lighting fixtures are not used effectively in areas where work passages are not formed, and the number of lighting fixtures is large. There was a problem in that this resulted in an increase in costs.

Therefore, in the 1970s, a mobile shelving device I was developed that could reduce costs.
No. 6-46588.

FIG. 5 shows a side view of the device I. As shown in the figure, five shelves 41 to 45 are arranged along the left-right direction.

Of these, the shelves 41, 45 at both ends are fixed, and the remaining shelves 42, 43, 44 are arranged in parallel so as to be movable in the left-right direction. Further, a rail 46 is hung between the upper portions of the shelves 41, 45 at both ends, and a lighting fixture 47 is attached to the rail 46, which is movable along its longitudinal direction.

In this movable shelf device I, as shown in FIG. 5, for example, when a working passage P is formed between the shelves 44 and 45, the lighting fixture 47 is moved above the working passage P, While only the working passage P is illuminated, when the working passage P is formed between the shelves 41 and 42 as shown in FIG. 6, the lighting fixture 47 is moved above the working passage P. Then, only the working passage P is illuminated. Since only the area where the work passage P is formed is illuminated by one lighting fixture 47, the lighting fixture 47
is effectively utilized, the number of lighting fixtures 47 is reduced, and costs can be reduced.

However, since it is necessary to install rails 46 that support the lighting fixtures 47 in a movable manner between the shelves 41 and 45, the shelves 41 and 45 at both ends
It is necessary to fix 1.45 respectively. For this reason,
The dimensions between the shelves 41 and 45 are always constant, making it a movable shelf device■
When not in use, it is not possible to move all of the columns 41 to 45 to one side, resulting in a problem in that the dedicated space when not in use becomes large.

On the other hand, FIG. 7 shows another conventional movable shelf device (2).

As shown in the figure, in this movable shelf device (2), by appropriately moving the ten shelves 51 to 60 arranged in parallel, a maximum of three working paths P can be formed between the shelves 51 to 60. It is configured as follows. Furthermore, the shelves at both ends 51.60
A rail 64 is hung between the upper parts of the lamps, and three lighting fixtures 61, 62, and 63 are movably mounted on the rail 64.
62 and 63 are moved onto the work passage P to illuminate the inside of the passage.

In this movable shelf device (2), it is the same as above, in addition to the need to attach the rail 64, the shelves 51 and 60 at both ends must be fixed respectively, and it is possible to move all the shelves 51 to 60 to one side when not in use. Since this is not possible, the dedicated space when not in use becomes large.

In addition, in the movable shelf device (2) in which a plurality of work passages P are formed, for example, as shown in FIG.
A working passage P is formed between the shelves 56 and 57, and a second lighting fixture 62 is arranged above it, and a working passage P for two passages is formed between the shelves 56 and 57, and a third lighting fixture is placed above it. Even if a working passage P is formed between the shelves 58 and 59 in the state in which the shelves 63 are arranged, the inside of the passage cannot be illuminated.

In other words, the second and third lighting fixtures 62 and 63 that illuminate the respective work passages P between the shelves 53 and 54 and the shelves 56 and 57 are connected to the workers working in the passages, respectively. Above, you can't turn it off, and of course you can't move it. On the other hand, the first lighting fixture 61 is connected to the second lighting fixture 61. The rail 64 is blocked by the third lighting fixture 62, 63, and it is not possible to move above the shelves 58, 59. When a plurality of work passages P are formed in this way, there is a problem in that the inside of the passage may not be illuminated depending on the positional relationship of the lighting equipment.

(Objective of the Invention) The present invention solves the problems of the prior art described above, reduces costs, occupies a small space when not in use, and improves the condition of forming a working passage when a plurality of working passages are formed. To provide a movable shelf device capable of always illuminating the inside of an aisle without causing bitterness.
