[00027] Figures la and lb are views of a tool chest 10 that has been constructed with a case frame 100 (shown in Figure 3a) and decorative exterior panels including side panels 12, top panel 16, rear pane124, bottom pane120 and fi-ont finisliing panels 13a, 13b. The tool chest includes drawers 15 that slide on slider carriers (not shown) inounted to the case fi-ame 100. Figures 2a and 2b are views of a tool cabinet 50 that has been constructed with a case frame 100 (shown in Figure 3a) and decorative exterior panels including side panels 12', top panel 16', bottom pane120' and front finishing panels 13a', 13b'. The tool cabinet includes casters 34 and drawers 15' that slide on slider carriers (not shown) mounted to the case fraine 100. The details of the slider carriers and drawers are not described herein, as this mechanism is known in the art.
[00028] Figures 3a and 3b illustrate an exemplary case franie 100 that is used to construct the tool chest and cabinet shown in Figures 1 a-2b. The case fi=ame 100 has a U-shape made up of two side segments 110a, 110b connected at an edge to an intermediate seginent 110c. In the described embodiment, the intennediate seginent 110c serves as the bottom surface of the tool chest or cabinet. However, in other embodiments, the intermediate segment may serve as the top or rear surface of the tool cliest or cabinet.
Various slider carrier mounting holes are shown in the side segments 110a, 1 lOb. Slider carriers are connected to these holes in the side segrnents. The intermediate segment includes niounting holes 134 to which the casters 34 are mounted when the case frame 100 is used to construct a tool cabinet 50. The structure and construction of a tool chest frame is similar to a tool cabinet franie, with several coinmon exceptions. A tool chest typically is without casters and has a bottorn surface designed to accoinmodate restiiig on a flat surface, such as for example, a work bench or the top of a tool cabinet. The top surface of a tool chest may be hinged to allow for tool storage access within the tool chest.
