Abstract
A knock-down file cabinet and in particular, a vertical file cabinet wherein both the cabinet housing and each of the drawers have a knock-down construction. The drawers use either separate components that are slidably fitted together, or a single sheet of material that defines the bottom, side and back walls. Each drawer construction is usable within the cabinet housing so as to define a complete knock-down vertical file cabinet which can be readily shipped in a relatively compact container or package and thereafter assembled together.

8. In a file cabinet including an enclosure having a hollow interior, said enclosure being defined by upstanding first and second side walls which each have front and rear edges, an upstanding back wall which extends laterally between said rear edges of said first and second side walls and a front support frame which joins said front edges of said first and second side walls together and permits access to said hollow interior, comprising the improvement wherein said back wall is defined by opposite first and second vertical side edges which each include a plurality of vertically spaced apart back wall connector parts, each of said rear edges of said first and second side walls including a plurality of vertically spaced apart side wall connector parts wherein each of said side wall connector parts is engagable with a respective one of said back wall connector parts, said side wall connector parts being engaged with said back wall connector parts by relative vertical movement therebetween such that each of said rear edges is removably engaged with a corresponding one of said first and second side edges of said back wall, one of said back wall and side wall connector parts being apertures and the other of said back wall and side wall connector parts being projections which are insertable into said apertures and engagable therewith by relative movement between said back wall and said rear edges of said side walls, said back wall and said first side wall being connected together by movement of said back wall horizontally and then downwardly relative to said first side wall, and said back wall and said second side wall being connected together by movement of said second side wall horizontally and then downwardly relative to said back wall, said file cabinet further including lock members which are removably engaged between said side edges of said back wall and said rear edges of said first and second side walls to prevent relative vertical movement therebetween;
- and
said support frame including a pair of laterally spaced apart vertical rails, each of said front edges of said first and second side walls opening rearwardly to receive a respective one of said vertical rails therein to rigidly join said front edges of said side walls together in laterally spaced relation. - View Dependent Claims (9)
