    摘要： The present invention provides a rotatable tower for holding and displaying books, video cassettes, and like articles on a plurality of square shelves which extend in horizontal planes and are supported in vertically spaced relation to one another by a plurality of vertically extending rods, groups of which are interconnected into L-shaped configurations by L-shaped, horizontally extending rods. The shelves include an elongated slot formed from the midpoint of each edge inwardly towards the shelves' geometric center, and two laterally spaced notches formed in each edge to one side of the slot. Each edge of the shelves includes a downwardly extending flange along their entire lengths and an upwardly extending flange along a portion of the length to the opposite side of the slot in which the notches are formed. Each L-shaped group of vertically extending rods is comprised of four rods, two rods forming each leg of the L. The rods in each group are spaced from one another a distance corresponding with the length and spacing of the slot and notches formed in each edge, thereby permitting one group of rods to engage the slot and notches formed in each edge of each shelf. Each shelf can be slid downwardly on the rods until they engage the adjacent horizontally extending L-shaped rods which interconnect the vertically oriented rods. The shelves' downwardly extending flanges will prevent the horizontally oriented rods, and hence the vertically oriented rods, from becoming disengaged from the shelves. Moreover, the engagement of one set of L-configured rods with each edge of each shelf systematically divides each shelf into four distinct article supporting regions.

    摘要翻译： 本发明提供了一种用于在多个方形搁架上保持和展示书本，录像带等物品的可旋转塔架，其在水平面中延伸并且通过多个垂直延伸的杆彼此以垂直间隔的关系相互支撑， 它们通过L形水平延伸的杆相互连接成L形构造。 搁板包括从每个边缘的中点朝向货架的几何中心形成的细长槽，以及在每个边缘中形成的两个横向间隔开的槽口到槽的一侧。 搁板的每个边缘包括沿其整个长度的向下延伸的凸缘和沿着长度的一部分向上延伸的凸缘，该凸缘沿着形成凹口的槽的相对侧。 每个L形的垂直延伸的杆组由四个杆组成，两个杆形成L的每个腿。每个组中的杆彼此间隔开一定距离，该距离对应于槽的长度和间隔以及在每个中形成的凹口 从而允许一组杆接合在每个搁架的每个边缘中形成的狭槽和凹口。 每个搁板可以在杆上向下滑动，直到它们接合相互垂直定向的杆相互水平延伸的L形杆。 搁架的向下延伸的凸缘将防止水平定向的杆，并且因此垂直定向的杆不会从搁架上脱离。 此外，一组L形杆与每个搁架的每个边缘的接合系统地将每个搁板分成四个不同的物品支撑区域。
