Description

[Detailed description of the invention] The present invention provides a movable shelf in which a movable shelf body is movably provided in the left and right direction in front of a fixed shelf row, and a sliding door is provided between the fixed shelf row and the movable shelf body. This invention relates to a guide device for a type door.

Conventionally, in this type of movable shelf, a row of fixed shelves is arranged on the rear side of the top surface of a deck, a ground rail is provided on the top surface of the deck in front of the fixed shelf row, and a movable shelf body is placed on this ground rail so that it can move freely from side to side.However, since the upper end of the ground rail is exposed from the deck, a deck cover body is provided on the top surface of the deck.

On the other hand, a sliding door whose upper end is suspended from an upper rail attached to the front upper part of the fixed shelf row is provided on the front part of the fixed shelf row, and the lower end of this sliding door is movable from side to side. It was configured to be guided by a lower rail provided at the bottom of the shelf row. However, the deck cover body and the lower door rail are formed separately, and it is necessary to suspend the sliding door so that it can move left and right after each of these members is attached, which simply requires a large number of parts. In addition to this, there were also drawbacks such as increased installation work and complicated construction.

The present invention solves the above problem by bending the rear end of the deck cover body that covers the upper surface of the deck in front of the fixed shelf row to form a lower rail that guides the lower part of the sliding door.

Next, an example of the present invention will be explained with reference to the drawings. In the drawings, 1 is a deck, and in the rear half of the upper surface of the deck 1, there are a plurality of fixed shelves 2 (three in the embodiment) with open fronts arranged in a row. They are arranged side by side in a row to form a fixed shelf row.

An upwardly U-shaped cross-sectional U-shaped frame body 3 in the deck 1
is arranged in front of and parallel to the fixed shelf row, and a ground rail 4 is arranged in the groove of the frame body 3 along the fixed shelf row. On the top surface of the frame 3 of this deck 1,
A pair of front and rear deck cover bodies 5, 6 are attached to the ground rail 4 except for the vicinity of the upper end using means such as bolts 7.

Reference numeral 8 denotes a plurality of movable shelves (two in the embodiment) that can be individually moved laterally along the front surface of the fixed shelf row;
The front side of each movable shelf 8 is provided with a double door 9, an upwardly rotating door 10, etc. as shown in the figure. A pair of wheels 11, 11 provided on the lower surface of each movable shelf 8 are rotatably mounted on the ground rail 4, and a pair of left and right cross sections are upside down L on the upper end of the back surface of each movable shelf 8. Brackets 12, 12 are provided to protrude rearward, and vertically supported rotating rollers 13 are provided protruding from the horizontal lower surface of each bracket 12, and each of these rotating rollers 13 is brought into contact with a rail device 14, which will be described later, from behind. I'm making you look like this.

The rail device 14 includes a vertical base 15 attached to the front surface of the fixed shelf row, a web portion 16 projecting forward from the base 15 in a substantially horizontal direction, and a vertical base portion 16 extending vertically from the front end of the web portion 16. Rib part 1
7 and a rail portion 18 formed by bending the lower end of the vertical rib portion 17 backward in a substantially horizontal direction. Vertical rib portion 17 of
The rear surface of the movable shelf 8 is formed into a rail surface 19 that the rotating rollers 13 of the movable shelf 8 come into contact with. In this embodiment, the upper end of the vertical rib portion 17 is bent backward to provide a flange portion 20, and the upper end of the vertical rib portion 17 is provided with a flange portion 20.
The rear end of the lower rail portion 18 is bent upward to form a flange portion 21. Further, in this embodiment, the base portion 15 and the web portion 16 are composed of a Z-shaped member with a horizontal cross section, and an L-shaped vertical rib member is welded to this to form a rail device.
As shown in FIG. 4, appropriate locations of 6 are cut and raised in the direction of the base 15 to form bolt attachment flange portions 22, and square holes 23 are bored in the flange portions 22. This rail device 14 may be integrally formed by extrusion molding or the like.

Reference numeral 24 denotes a sliding door that can be moved left and right along the front surface of the fixed shelf row, and a rotating roller 26 is mounted on each of a pair of left and right vertical seat plates 25, 25 that protrude from the upper end of the sliding door.
are horizontally supported, and each rotating roller 26 is placed on the rail section 18 above the web section 16 of the rail device, and the sliding door 24 is movably suspended.

An L-shaped bracket 27 is provided at the lower end of the sliding door 24 facing backward, and a slider 2 such as a rotating roller or a synthetic resin sliding body is mounted on the upper surface of the horizontal part.
8, the rear end of the deck cover body 6 on the rear side of the deck 1 is bent upward along the front end of the lower end of the fixed shelf row, and the upper end thereof is bent forward to form a downward open type lower part. The rail 29 is connected to the door 2
The sliding door 24 is integrally formed parallel to the upper rail 14 for 4, and the sliding door 24 is formed in an open groove of the lower rail 29
A slider 28 provided at the lower end of the holder is slidably engaged with the slider 28.

When the upper end of the sliding door 24 is suspended from the upper rail device 14 in this way, it is only necessary to guide the lower end of the sliding door 24 so that it does not move away from the front surface of the fixed shelf row. can be kept floating with respect to the deck cover body 6, and the weight of the sliding door 24 does not act on the lower rail 29, so there is no need to increase the strength of this lower rail 29. Even if the lower rail 29 is formed by bending the end, the lower rail 29 will not be damaged, and the lower part of the door 24 can be reliably guided, allowing the door 24 to be opened and closed easily.

In summary, according to the present invention, the lower rail that guides the lower end of the sliding door is formed by simply bending the rear end of the deck cover body, so manufacturing is extremely simple. Since it is formed integrally with the deck cover body that covers the upper surface, the lower rail can be installed together with the deck cover body simply by attaching it to the upper surface of the deck. Therefore, the deck cover body and the lower rail can be handled together. As a result, the number of parts can be reduced, and the number of man-hours for manufacturing and mounting and disassembling can be greatly reduced, leading to a reduction in manufacturing costs.

In addition, since the rear end of the deck cover body is bent upward along the front surface of the lower end of the fixed shelf row to form the lower rail of the sliding door, the lower end of the fixed shelf row is bent upward by this lower rail. There is no need to separately provide a decorative cover body at the lower end of this fixed shelf row.
