Abstract

PURPOSE:To widen a combinational shelf by expanding shelf frames when it is used, and fold up the shelf frames when it is not used in a carriage pivoting the combinational shelf composed of the multistage shelf frames juxtaposed in parallel with each other so as to be mountable and demountable. CONSTITUTION:A carriage has a structure that a pair of U-shaped shelf frames 13 pivoted opposite to each other so that both ends come inside between respective one end fixed pillars 8 in the same lengthwise direction with N-shaped rigid base parallel rails 1 and 2 having canisters 4 and 5 below and respective movable pillars 9 capable of approaching the fixed pillers 8 by moving on these rails, are pivoted so as to be mountable on/demountable from both pillars on the respective rails in both abdominal regions. A spring is installed between a base part of the fixed pillars of one rail and a base part of the movable pillars of the opposite side rail so as not to cross a rigid beam to connect both rails diagonally to each other. A common longitudinal bar 30 is pivoted by a central pivot part on the inside of the shelf frames 13 installed on one side rail, and when this longitudinal bar 30 is raised and lowered, the shelf frames 13 are expanded or folded up lightly and speedily.

When the movable column is separated from the fixed column and moved to the bowl 31 against the pressure of the spring 56, the pin 57 is fitted into the hole 59 and the link of the shelf frame is extended to form a plurality of combined shelves at once. To do. Items can be placed on the respective shelves according to the purpose. In this state, the pin 57 is tightly fitted in the hole 59, and the opposing shelves such as 17 and 18 have the opposite ends of the flanges represented by 50 and 51, especially when a load is placed. The shelves remain flat due to the abutments of each other. Therefore, the vertical bar 30 also takes the most lowered position.

まれる。When the vertical bar 30 is pushed up, one pivotal fulcrum of each shelf represented by 19 is pushed up, and with this, each of the representatives represented by 23, 24, 25, 26 attached to the pillar. Four shelf frames 13, 14, 15, 16 in the drawing including the pivot point and the other pivot point of each shelf frame typified by 20 including the abdomen 21 and 22 and the U-shaped frames 17 and 18. Is the inner end 19, 20
Try to form a triangle with the vertex as the vertex. At that time, the movable columns 7 and 9 start moving from the bowl toward the fixed column. At this time, the pin 57 fitted in the hole 59 begins to come out of the hole. Along with this, the spring 56 acts to pull the movable column 9 toward the fixed column 8 and then the other movable column 7, which is connected by the beams 11 and 12a, also starts moving toward the fixed column 6, and a light force is exerted by the spring force. Both movable columns 7 and 9 immediately move toward the corresponding fixed columns to the position shown in FIG. 3 and stop. Thus, the shelf frame is folded.

It can be accommodated so that the other base rail 2a of the second carriage is lined up outside the other base rail 2 of the first carriage. Therefore, a large number of carriages can be accommodated within a limited area in a folded state without removing the shelf frame.

Since it is detachably mounted between the fixed columns or the movable columns by inserting it into the column 5, if both columns are provided with holes corresponding to the holes 45, for example, 46, 47, etc., the shelf frame will be different. It can be installed and removed at an intermediate position. In this case, if the vertical bars 30 pivotally attached to the pivot points between the U-shaped frames are also provided with holes at the above-mentioned appropriate intervals, even if the position of the shelf changes, the common pivot point of the shelf frame can be used at other shelf positions accordingly. The hole of the vertical bar can be jointly used in common.

Simply moving the vertical bar up raises the center of the shelf frame slightly, which causes the movable column to move toward the fixed column by spring pressure and the shelf frame is folded. Since the shelf frame of the combined shelf structure is detachable from the above-mentioned pillar, the carriage can be used with the shelf interval set to a desired interval according to the size of the article. Each folded shelf frame is extremely thin, like a folding screen, and the occupancy area of the main part of the bogie is small. Since the base is N-shaped, the bases of other trolleys can be deeply arranged to accommodate a large number of trolleys in a small area.
