Claims

[Claims for Utility Model Registration] (1) Four tubular struts with casters attached to their lower ends, and the four corners of these tubular struts inserted through spacing tubes with predetermined spacing maintained. In the tray rack, the tray rack includes a plurality of tray support shelves, and a fixing device for fixing the tray support shelves to the tubular support so that the tray support shelves do not fall out of the tubular support. A tray rack characterized in that a spring is interposed between the spacing tube and the tray support shelf to prevent a gap from forming. (2) The fixing device includes a ring member having a rectangular insertion hole fixed to the upper side of the tubular support, a locking collar at the upper end that is inserted into the insertion hole of the ring member so as to be movable up and down, and a locking collar at the lower end. A slide shaft with a screw to which a nut is screwed, a screw hole or bolt formed at the top of the locking collar of this slide shaft, and an upper tray support shelf that is screwed into the screw hole or bolt. Utility model registration claim 1, characterized in that the ring member is composed of a bolt or a nut, and a spring is interposed between the ring member and the nut screwed into the thread of the slide shaft.
Trailer rack as described in section. (3) The fixing device includes a ring member having a circular insertion hole that is fixed to the upper side of the tubular support, a nut that is attached to the lower part of this ring member via a spring so that it can only move up and down, and this nut. The tray rack according to claim 1, characterized in that the tray rack is comprised of a bolt that holds down an upper tray support shelf that is screwed together. (4) The fixing device consists of a nut fixed to the upper end of the tubular support, and a bolt that tightens and fixes the upper tray support shelf that is screwed into this nut, and the spring has its lower end fixed to the lower end of the tubular support. 2. The tray rack according to claim 1, wherein the tray rack is interposed in a locked state between a spacer on the lower side whose upper end is inserted into the tubular support.
