Abstract

PURPOSE:To make a setting body securable to a fixed position after moving it, by making up a caster to be telescopic freely from and to the bottom support of the setting body. CONSTITUTION:Fitting a caster 7 in a hollow part 6, a screw 8 passes through a hole 4a and the caster's ring 7c is protruded beneath from the bottom 5 at a state of being threaded in a tapped hole 7a, operating as an ordinary moving rack. When the screw 8 is removed, the caster 7 is detached from a column 4, guided into a slit hole 4b with which the wall of the hollow part 6 and a pin 7b are fitted together and housed in the said hollow part. And, the ring 7c is made flush with the bottom plate 5 and the wheeled rack thus turns to a fixed rack.

３を突出させていた。Some electronic device storage racks have casters attached to the bottom plate of the rack to make it a movable rack. Conventionally, when attempting to fix this type of movable rack in a fixed position, a stopper mechanism provided on the casters was activated, and a level adjuster 3 provided separately from the casters 2 was protruded from the rack 1 as shown in Fig. 1. I was letting it happen.

があった。However, in this case, the entire load of the rack is supported by the casters or the level adjuster 3, so in the event of a disaster such as an earthquake, the stopper mechanism of the casters and the fixing function of the level adjuster 3 are likely to be damaged, resulting in an extremely dangerous situation. there were. Furthermore, as a matter of course, the center of gravity of the rack is located upward by the height of the casters, level adjuster 3, etc., which has the disadvantage of making it more likely to fall. In addition, in order to eliminate the above-mentioned drawbacks, when attempting to fix the rack after removing casters, level adjusters, etc., the removed casters,
A new storage location for level adjuster 3, etc. is required.
Further, there was a drawback that the main body of the frame had to be laid down when being removed.

の実施例と共に説明する。In order to eliminate the above-mentioned conventional drawbacks, the present invention provides casters that protrude from a mounting body such as a frame so that they can be freely stored, and will be described below along with an embodiment thereof.

第２図および第３図において、４は取付体としての架に

Reference numeral 6 denotes a bottom plate of the frame to which the pillar 4 is fixed. 6 is a hollow part formed by the column 4 and the bottom plate 6, 7 is a caster, and a pin 7 that fits into an elongated hole
b, a screw hole 7a corresponding to hole 4& is provided. 7
C is the ring of the caster 7. 8 connects the caster 7 to the hollow part 6
It penetrates the hole 4a in the state where it is fitted into the screw hole 71.
This is a screw that screws into the caster 7 to fix the caster 7.

When the screws 8 pass through the holes 4a and are screwed into the screw holes 7a, the rings 70 of the casters 7 protrude downward from the bottom surface 6, as shown in FIG. Work as.

さに位置し、架は固定架となる。Also, by removing the screw 8, the caster 7 and the column 4 are uncoupled, and the caster 7 is attached to the wall of the hollow part 6, the pin/7b
is guided into the fitted elongated hole 4b and housed in the hollow part 6. FIG. 5 shows this state, in which the ring 7C is located at the same height as the bottom plate 6, and the rack becomes a fixed rack.

る。In addition, since the pin 7b is fitted into the elongated hole 4b, the caster 7
This prevents the casters from entering the hollow portion 6 more than necessary, prevents the casters from falling off, and facilitates alignment of the holes 4a and screw holes 7a when screwing.

このような実施例において、通常は部屋の隅やせまい部

、移動後容易に固定架とし安全な作業ができる。In such embodiments, it is usually installed as a fixed rack in the corner of a room or in a small room, but when maintenance or inspection is to be carried out in a large space, it can be easily made into a movable rack, and it can be easily fixed after being moved. You can work safely using it as a stand.

ができる。As is clear from the above description, according to the present invention, the casters are configured to protrude from the bottom of the mounting body and can be stored freely, so that the mounting body can be securely fixed in a predetermined position after being moved. Can be done. Furthermore, when the casters are stored, the center of gravity of the mounting body is lowered, so that the casters can be fixed even more stably.
