1 CONVEYOR-TYPE FOLDUP TOOL CHEST BASE SUMMARY ble characteristics. The base permits chest to be placed in ordinarily awkward places such as: under cabinets, benches, or rear deck sides of automobiles inside the trunk. Simply roll chest under such places on conveyor base and then fold up base half to save space.

BRIEF DESCRIPTION OF VIEWS Fig. 1. This is a top view of base showing nearly all elements. Base folds in center by use of hinges to permit space saving and base is adjustable on the ends to accommodate most sizes of tool chests.

FIG. 2. This is a side view showing leg supports and adjustability of foldup side of base when it rests in horizontal position.

FIG. 3. This is a partial view of roller angle rails showing rollers and protective guide strip on inside vertical leg of roller angles. I
