Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rail device for a movable shelf in which a movable shelf body is provided movably in the left and right directions in front of a fixed shelf row.

Conventionally, in this type of movable shelf, a guide rail with a U-shaped cross section is provided at the upper front of the fixed shelf row with its opening groove facing forward, and this guide rail covers the roller guide at the upper part of the movable shelf body and the front surface of the fixed shelf row. There is a rail device that doubles as a guide for the upper roller of a sliding door.

The opening groove of this U-shaped guide rail faces toward the back of the movable shelf, and the head of the bolt attached to the opening enters the field of view of the person facing the opening groove of the guide rail, making the appearance difficult. It was hot because it was hard to see.

In this invention, this type of rail device has a horizontal cross-section T.
It is an attempt to maintain a beautiful appearance by constructing it with a molded long rail member.

Next, an example of the present invention will be explained with reference to a drawing.
In the figure, 1 is a deck, and on the rear half of the upper surface of the deck 1, a plurality (three in the embodiment) of fixed shelf bodies 2 with open fronts are arranged 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 disposed in front of and parallel to the fixed shelf row, and a ground rail 4 is disposed within the groove of the frame body 3. This frame 3
On the upper surface of the front part, there is a cover body 5 which also serves as a lower stile.
A deck cover body 6 is attached to the rear part with the ground rail 4 interposed therebetween using bolts 7, etc., respectively.

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-sectional upside-down L is provided at 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 of the present invention includes a vertical base portion 15 attached to the front surface of the fixed shelf row, a web portion 16 protruding forward from the base portion 15 in a substantially horizontal direction,
A cross-sectional sideways T formed integrally with a vertical rib portion 17 extending vertically from the front end of the web portion 16 and a rail portion 18 formed by bending the lower end of the vertical rib portion 17 backward in a substantially horizontal direction. It is made of a molded long rail member, and the rear surface of the vertical rib portion 17 above the web portion 16 is configured as a rail surface 19 on which the rotating rollers 13 of the movable shelf 8 come into contact.
In this embodiment, a flange portion 20 is provided by bending the upper end of the vertical rib portion 17 backward, and a flange portion 21 is provided by bending the rear end of the rail portion 18 below the web portion 16 upward. There is. 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 member to form a rail device. As shown in Figure 4, the base 1
Flange part 22 for bolt mounting by cutting in five directions
A square hole 23 is formed in the flange portion 22. The rail device 14 of the present invention 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 example, 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.
The rotating rollers 26 are placed on the rail section 18 below the web section 16 of the rail device, and the sliding door 24 is movably suspended.

An L-shaped bracket 27 is provided facing backward at the lower end or lower back surface of the sliding door 24, and an engaging portion 28 such as a rotating roller or a synthetic resin sliding body is provided protruding from the upper surface of the horizontal portion. The rear end of the deck cover body 6 in No. 1 is bent upward along the front end of the fixed shelf row, and the upper end thereof is bent forward to form a guide portion 29 that is open downward. The engaging portion 28 on the lower end or back surface of the sliding door 24 is configured to face inside the open groove of the guide portion 29. Since the guide part 29 that guides the lower part of the sliding door 24 is formed integrally with the deck cover body 6 that covers the top surface of the deck 1 in this way, the number of parts can be reduced and the man-hours for manufacturing and installation and removal can be greatly reduced. This has the effect of reducing manufacturing costs.

In order to attach the rail device 14 to the front surface of the fixed shelf row, for example, a mounting hole is drilled in advance in the front surface of the upper stile 30 of each fixed shelf body 2, and bolts are attached to the long rail member with a horizontally T-shaped cross section. Insert the square root round head bolt 31 toward the square hole 23 of the flange portion 22, and tighten the nut 32 from the back side of the upper stile 30 at the mounting hole location. This prevents the bolt 31 from rotating.

In summary, according to the present invention, the rail device is a long rail member with a horizontally T-shaped cross section, and the vertical rib portion can cover and hide the base in front of the base attached to the front surface of the fixed shelf row. Bolt heads and the like are not exposed, making the appearance beautiful and clean. The rail surface of the rotating roller on the back of the movable shelf and the rail section of the upper rotating roller of the sliding door are both provided on the back (rear) side of the vertical rib section, so these parts are not contaminated with lubricating oil, etc. However, it cannot be seen from the front and there is nothing to look at. In addition, since it is only necessary to paint the front side of this vertical rib part, the painting area can be reduced.
Furthermore, since the rotating rollers do not come into contact with this painted area, it will not peel off. Since the rotating rollers of the movable shelf can face the rear surface of the vertical rib part above the substantially horizontal web part of the rail device from above, the rail device can be fixed not only at the upper end of the fixed shelf row but also at an appropriate height position. It also has the advantage that it can be provided at the front position of the shelf row.
