Description

The present invention relates to a fall inhibitor used for transporting racks.

When transporting the rack, it is necessary to lower the center of gravity of the entire rack so that the rack does not become unstable, considering the rise and fall of steps and slopes in the route to the installation destination. This requirement limits the weight of equipment (units) that can be mounted in a rack.

In recent years, there has been an increasing demand for higher functionality and space saving of devices, and it is often the case that tall racks are adopted or units are mounted at high density in the racks. Therefore, the center of gravity of the entire rack tends to be high. However, due to the function of the device, it is often not possible to lower the center of gravity of the entire rack. In that case, by attaching an auxiliary caster that can be attached and detached during transportation, it may be possible to prevent the vehicle from tipping over during transportation.

When using auxiliary casters, the auxiliary casters may be removed after the rack is installed in order to minimize the area occupied by the rack at the installation site. The removed auxiliary casters need to be stored for a long period of time until the rack is discarded or removed. For equipment that is operated for a long period of time, the storage period may extend to 10 years or more. Therefore, securing a storage place for auxiliary casters and preventing loss are issues.

Patent Document 1 discloses an example of an auxiliary caster that prevents the rack from tipping over during transportation and is stored after the rack is installed. In the caster 1 with an arm of Patent Document 1, a leveler 8 and a support 9 are attached to four corners of a bottom plate 7 of a housing 6 of an electronic device or the like by screwing in pairs. Here, when moving the housing 6, the end concave 5 of the arm 3 is hooked on the bottom plate 7 of the housing 6 by the support tool 9 to stop the rotation of the arm 3, and the caster 2 is the housing. The tip of the arm 3 is projected so as to be located on the outside of 6. Then, the height of the leveler 8 is adjusted so that the caster 2 is grounded. Next, when installing the housing 6, the leveler 8 is lowered and grounded, and the caster 2 is lifted from the installation surface. Then, the support 9 is loosened to release the hook of the end concave portion 5, and the caster 1 with an arm is rotated in the direction of the arrow and stored in the bottom surface side of the housing 6. As a result of the above configuration, in the caster 1 with an arm of Patent Document 1, the housing 6 is stably installed within a fixed area.

Japanese Unexamined Patent Publication No. 2004-200564

The caster with an arm of Patent Document 1 is installed at a position visible from the outside. Therefore, the caster with an arm of Patent Document 1 has problems such as spoiling the appearance of the rack, hindering the arrangement of cables, hindering cleaning, and collecting dust.

The present invention has been made in view of the above problems, and an object of the present invention is to prevent a fall during transportation of a rack and to realize a fall prevention tool that is stored in the rack after the rack is installed.

In one aspect of the present invention, the fall deterrent device is attached to the rack, and when an external force for overturning the rack is applied, the fall deterrent unit supports the fall deterrent unit and the fall deterrence unit, and is attached to and detached from the rack. It includes a mountable part that can be mounted and a mount part that is detachably mounted on the rack with the fall prevention part and the mount part stored in the rack.
