Description

[Detailed Description of the Invention] This invention relates to an improvement of a traveling device for a movable shelf.

Recently, movable shelves in which the shelves can run along rails have come into wide use in order to make effective use of space. This movable shelf is moved by a pair of wheels rolling on two rails, but it is inevitable that each rail will have unevenness in the length direction, so there are four One of the wheels did not come into contact with the rail, which caused the movable shelf to tilt and wobble, impeding smooth running.

This invention was made to solve these conventional drawbacks, and it allows the four wheels to reliably contact the rail even if the rail is uneven, and
To provide a device that prevents a movable shelf from tilting and allows smooth running.

Embodiments of this invention will be described below with reference to the drawings. In FIG. 1, a movable shelf 1 has a pair of wheels 3 and 4 on both sides, and is configured to move along the rail 2 by rolling on the rail 2. As shown in FIG. These wheels 3 and 4 are the second to
It is installed as shown in Figure 4. That is,
Wheels 3 and 4 rolling on the rail 2 are rotatable around axles 6 and 6 attached to both ends of the wheels while being interposed between a pair of bearing members 5 and 5 that are arranged opposite to each other. The bearing members 5, 5 are rotatably held around a support shaft 7 attached to reinforcing members 11, 11 at an intermediate position between the wheels 3 and 4.

In addition, a bracket 8 is attached to the top of the movable shelf main body 10.
0 and 80, the anti-falling rollers 8 and 8 are rotatably supported in the same direction as the wheels 3 and 4, respectively. The anti-falling rollers 8, 8 are configured to roll on a guide rail 9 that is horizontally supported by a fishing bracket 90 from the ceiling.

In the above configuration, the load of the movable shelf 1 is transmitted from the reinforcing member 11 to the wheels 3 and 4 through the shaft 7 and the bearing member 5. Therefore, the movable shelf 1 is supported at two points, the left and right support shafts 7, 7, and therefore, even if the rail 2 has unevenness in the longitudinal direction while the movable shelf 1 is running, the bearing members 5, 5 will not interfere with the longitudinal unevenness. By tilting accordingly, both wheels 3, 4 are always in contact with rail 2, and the load is almost evenly distributed to both wheels 3, 4. If the pair of wheels 3 and 4 are each directly attached to the movable shelf main body 10, one of the wheels will float off the rail 2, but in the above configuration, the bearing member 5 is moved to the support shaft 7 according to the unevenness of the rail 2. By rotating around the wheels 3 and 4, an equal load is applied to both wheels 3 and 4.
4 is brought into contact with the rail 2. On this occasion,
The movable shelf 1 is always held in a horizontal state by anti-falling rollers 8, 8 and guide rails 9, and can run smoothly without tilting or wobbling.

As shown in FIG. 5, a regulating roller 81 for regulating lateral movement is horizontally supported at an intermediate position between the anti-falling rollers 8 and 8 of the movable shelf main body 10, and this regulating roller 81 has a U-shape. By configuring the movable shelf 1 to be restricted by the side walls 92, 92 of the guide rail 91 formed in the movable shelf 1, the movable shelf 1 is prevented from swinging from side to side, and smoother travel is possible.

In the above embodiment, an example is shown in which the movable shelf 1 is moved in the depth direction thereof, but it may be configured to be moved in a direction perpendicular to this.

Further, in the above embodiment, the anti-falling rollers 8, 8 and the regulating roller 81 are attached to the side plate of the movable shelf main body 10, but they may be attached to the upper surface of the top plate. Furthermore, the guide rail 9 or 91 can also be fixed to an appropriate side wall surface.

As explained above, in this invention, a pair of wheels of a mobile shelf are interposed between a pair of bearing members and are held rotatably around the axles, and this bearing member is held by a single support shaft. By supporting the main body of the movable shelf at two points, one on the left and right, the four wheels are always in contact with the rail regardless of the unevenness of the rail, and the movable shelf is moved by providing anti-falling rollers and guide rails. The shelf is always kept in a horizontal state, which allows for smooth movement of the shelf.
