Description

Title Rotatable Pedestal

Background

This application claims priority from US Application No. 60/789,537, filed April 4, 2006, and is related to US Publication No. 2004/0124324 and US Patent No. 6,688,573, the disclosures of which are incorporated herein by reference.

This invention relates to pedestals. The term "pedestal" is used herein to denote a structure placed on a horizontal surface to support objects placed on top of, or at intermediate levels of, the pedestal. For example, pedestals are widely used in the catering and hospitality industry to support serving dishes, containers, platters, trays, jugs, glasses, bottles, cutlery, ice sculptures and flower vases at positions chosen for functional and/or decorative reasons. Summary of the Invention

We have discovered, in accordance with the present invention, novel pedestals and novel pedestal components. In normal use, the pedestals of the invention comprise one or more generally vertical components, referred to herein as "columns", and one or more generally horizontal components, referred to herein as "supports". The references herein to vertical, horizontal, top, bottom, upper and lower assume that the pedestal is being used normally. However, the invention includes the possibility that the pedestal is in a different orientation, and the terms vertical and horizontal are used to include variations from the strictly vertical and strictly horizontal directions which do not have any substantial effect on the function of the components in question.

In a first preferred aspect, this invention provides a pedestal which comprises (1) a first lower vertical column having a top and a bottom and a first lower vertical axis,

(2) a first upper vertical column having a top and a bottom and a first upper vertical axis which is different from the first lower vertical axis, and

(3) a first intermediate horizontal support having a lower surface and an upper surface; the lower surface of the first intermediate support being rotatably connected to the top of the first lower column so that the first intermediate support can be rotated in a horizontal plane relative to the first lower column; and the upper surface of the first intermediate support being connected to the bottom of the first upper column so that rotation of the first intermediate support relative to the lower column changes the relative positions of the first upper vertical axis and the first lower vertical axis.

The term "vertical axis" is used herein in relation to a column to denote a vertical line which passes through the center of gravity of the column. Preferably the connection between the upper surface of the first intermediate support and the bottom of the first upper column is a rotatable connection such that the first intermediate support can be rotated in a horizontal plane relative to the first upper column.

In a second preferred aspect, this invention provides a support which can be used as the first intermediate support of a pedestal according to the first aspect of the invention, the support comprising a lower surface having a lower conformation which enables a lower column to be rotatably connected thereto and an upper surface having an upper conformation which is laterally offset from the lower conformation and which enables an upper column to be rotatably connected thereto. In other preferred aspects, this invention provides (A) a kit containing components for assembling one or more pedestals of the first aspect of the invention; (B) a method of making a pedestal according to the first aspect of the invention, the method comprising placing, preferably placing by manual forces only (i.e. without the use of tools), pedestal components together; and (C) a method of displaying objects which comprises placing, preferably manually placing, the objects on a pedestal according to the first aspect of the invention. Detailed Description of the Invention

In the Summary of the Invention above, and in the Detailed Description of the Invention, and in the accompanying drawings, reference is made to particular features of the invention. It is to be understood that the disclosure of the invention in this specification includes all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a particular aspect, a particular embodiment, or a particular Figure, that feature can also be used, to the extent appropriate, in the context of other particular aspects, embodiments, and Figures, and in the invention generally.

The term "comprises" and grammatical equivalents thereof are used herein to mean that other elements (i.e. components, ingredients, steps etc.) are optionally present. For example, a pedestal "comprising" (or "which comprises") components A, B and C can contain only components A, B and C, or can contain not only components A, B and C but also one or more other components. The term "at least" followed by a number is used herein to denote the start of a range beginning with that number (which may be a range having an upper limit or no upper limit, depending on the variable being defined). For example "at least 1" means 1 or more than 1. When, in this specification, a range is given as " (a first number) to (a second number)" or "(a first number) - (a second number)", this means a range whose lower limit is the first number and whose upper limit is the second number. For example, "from 8 to 20 inches" or "8-20 inches" means a range whose lower limit is 8 inches, and whose upper limit is 20 inches. The terms "plural" and "plurality" are used herein to denote two or more than two items.

Where reference is made herein to "first" and "second" elements, this is often done for identification purposes; unless the context requires otherwise, the first and second elements can be the same or different, and reference to a first element does not mean that a second element is necessarily present (though it may be present). Where reference is made herein to "a" or "an" element, this includes the possibility that there are two or more such elements (except where the context excludes that possibility). Where reference is made herein to two or more elements, this includes the possibility that the two or more elements are replaced by a lesser number or greater number of elements providing the same function (except where the context excludes that possibility). The numbers given herein should be construed with the latitude appropriate to their context and expression; for example, each number is subject to variation which depends on the accuracy with which it can be measured by methods conventionally used by those skilled in the art. First Aspect of the Invention The pedestals of the first aspect of the invention often include at least one additional column and/or at least one additional support.

In one exemplary embodiment, the pedestal further comprises

(4) a second lower vertical column having a top and a bottom and a second lower vertical axis, (5) a second upper vertical column having a top and a bottom and a second upper vertical axis which is different from the second lower vertical axis, and

(6) a second intermediate horizontal support having a lower surface and an upper surface; the lower surface of the second intermediate support being rotatably connected to the top of the second lower column so that the second intermediate support can be rotated in a horizontal plane relative to the second lower column; and the upper surface of the second intermediate support being rotatably connected to the bottom of the second upper column so that rotation of the second intermediate support relative to the second lower column changes the relative positions of the second upper to the vertical axis and the second lower vertical axis; and

(7) an auxiliary horizontal support having a lower surface which is (a) rotatably connected to the top of the first upper column, and (b) rotatably connected to the top of the second upper column. In another exemplary embodiment, the pedestal further comprises

(4) an auxiliary column having a third vertical axis, and

(5) an auxiliary support having a lower surface which is (a) rotatably connected to the top of the first upper column, and

(b) rotatably connected to the top of the auxiliary column.

In another exemplary embodiment, the pedestal comprises

(1) a first cylindrical lower column having a top, a bottom, and a first lower vertical axis, (2) a first cylindrical upper column having a top, a bottom, and a first upper vertical axis which is different from the first lower vertical axis,

(3) a first intermediate support having a lower surface and an upper surface;

(4) a second cylindrical column having a top, a bottom and a second vertical axis which is different from (i) the first lower vertical axis and (ii) the first upper vertical axis; and

(5) an upper support; the lower surface of the intermediate support including a recess into which fits the top of the first lower column so that the first intermediate support can be rotated relative to the first lower column about the first lower vertical axis; the upper surface of the intermediate support including a recess into which is fitted the bottom of the first upper column so that the first intermediate support can be rotated relative to the first upper column about the first upper vertical axis; and the upper support having a lower surface which includes (a) a recess into which fits the top of the first upper column so that the upper support can be rotated relative to the first upper column about the first upper vertical axis, and

(b) a recess into which fits the top of the second column so that the upper support can be rotated relative to the second column about a second vertical axis which is different from (i) the first lower vertical axis and (ii) the first upper vertical axis.

As will be apparent to those skilled in the art from that their own knowledge and the disclosure in this specification, a very wide variety of pedestals can be assembled using one or more pedestals according to the first aspect of the invention and a plurality of additional support members and/or columns, most or all of the connections between the columns and the support members being rotatably adjustable so that the pedestal can be fitted to the horizontal space available for the pedestal and provide desired surfaces for displaying objects. The rotatable connections between a column and a support can be of any kind.

Spaced-apart connections in the same pedestal can be the same or different. The connection is preferably such that the support and the column can be assembled together, and/or disassembled, by manual forces only, i.e. without the use of tools of any kind. Preferably, the rotatable connection, once made (with or without the use of tools) is maintained by the forces of gravity only (including the weight of any objects on the pedestal).

In a preferred form of connection, the end of the column fits into a recess in the support or a projection on the support fits into a recess in the column. Preferably the end or the projection can rotate in the recess. Alternatively, the end or projection can be fixed in the recess, and the end, projection or recess can rotate relative to the remainder of the column and/or the support.

In some embodiments, the end or projection and the recess have dimensions such that the end or projection is capable only of rotational movement relative to the recess. For example, the end of a solid round column can fit into a round recess in a support; or the end of a column which is a cylindrical shell can fit into a round or annular recess in a support; or the support can have a cylindrical or annular projection which fits into or around the end of a column having an end which is a cylindrical shell or a cylinder. In other embodiments, the recess has dimensions such that both rotational and lateral movement is possible; for example, a column having a round end fits into a channel having the same width as the diameter of the end, the channel being straight or curved and preferably having semicircular ends.

The columns used in the present invention can be the same or different. The columns can have any cross-section, and the cross-section can be the same or different over the length of the column. For example, one or both ends of the column can have a cross section which will fit into, and rotate within, a recess in the support(s) to which the column is rotatably connected, e.g. an annular, round, equilateral triangular or other regular polyhedral (including fluted) cross-section; and the remainder of the column can have the same or a different cross-section. The corresponding recess in the support can be round or, particularly when the column has an annular or round cross-section, a channel into which the end of the column can be rotatably fitted. The column can be of any length (i.e. height) and/or width (e.g. diameter). In some embodiments, the column is no longer than is necessary to provide a rotatable connection between two support members, i.e. has a length which is substantially equal to the sum of the depths of the recesses in the supports which the column connects (in which case the column is not an important part of the visual appearance of the pedestal). Generally, however, at least one of the columns has a substantial length, for example at least 1 inch (25 mm), e.g. 2-10 inch (50-255 mm) (75-180 mm). The length of the column can be, for example, from 0.5 to 5 times the effective diameter of the column (the term "effective diameter" being used to denote the diameter of a cylindrical column or, for a non-cylindrical column of constant cross section, the diameter of a circle having the same cross-sectional area as a non- cylindrical column. The horizontal supports used in the pedestals of the invention, including but not limited to, supports according to the second aspect of the invention, can be of any size and shape which enables the support to provide the defined functions. Generally the support is of uniform thickness, for example 0.25 to 1 inch (6 to 25 mm), or 0.4 to 0.7 inch (10 to 18 mm), e.g. about 0.5 inch (13 mm). The shape of the support can for example be circular or oval or other regularly curved shape, or rectangular (including square), e.g. with rounded corners. The area of the support can for example be 5 to 400 in.² (0.003 to 0.25 m²), or 10 to 200 in.² (0.006 to 0.125 m²), for example 50 to 150 in.² (0.015 to 0.05 m²). The conformations in the upper and lower surfaces of the support, which can be the same or different, can for example be recesses or projections. The outer periphery of a recess can, for example, be annular, round, or a regular polyhedron, so that a column which has a round cross-section, or another suitable cross section, can be fitted into and can rotate in the recess. The whole of the area within the periphery can be recessed, or, when for example the column has an annular cross section, at least at the end which fits into the recess, the recess can be annular in cross-section. (The term "annular" is used herein to include cross sections which are of irregular width When the conformation is a projection, it can be of any cross-section which will fit into a column which is recessed at the end into which the projection fits (and which may be hollow throughout its length) so that the column can rotate around the projection.

In some embodiments, the lower conformation is positioned so that the center of gravity of the support, when it is generally horizontal, lies within the conformation; for example the support is round, and the lower conformation has the same center as the support. In this way, the support can rest stably on a lower column which is fitted to that conformation. The upper conformation can be positioned so that the center of gravity of an upper column fitted thereto lies inside or outside the lower column. The weight of the support member can be substantially greater than, for example 2 to 20 times, or 4 to 10 times, the weight of at least the upper column fitted thereto, and optionally also by weight of the lower column fitted thereto.

When a pedestal of the invention includes a column whose top is not covered by a support, the top of the column can optionally include two or more channels into which can be slidably fitted two or more parallel horizontal support members as disclosed for example in US Publication No. 2004/0124324. For example, the upper periphery of a hollow cylindrical column can comprise 3-6 pairs of channels with 3-6 support members slidably fitted thereto.

Referring now to the drawings, Figures 1 and 2 are side and plan views of a a pedestal of the invention comprising first and second pedestal bases 1 and 2 and an upper support 3. The first pedestal base comprises a lower cylindrical column 11 having an annular cross-section, an upper cylindrical column 12 having an annular cross-section, and an intermediate support 51 to which the upper and lower columns are rotatably connected. The second pedestal base comprises a cylindrical column 2 having an annular cross-section. The upper support 3 is rotatably connected to the top of the upper column 12 and to the top of the column 2. Figures 3 and 4 are cross- sections of the supports 3 and 51 , showing the circular grooves into which the columns 11, 12 and 2 are rotatably fitted. The supports 3 and 51 could for example alternatively be formed with circular recesses in place of the circular grooves, making it possible for the columns to be solid and/or to have a non-circular cross section which can fit into, and rotate within, the recess.
