Problems solved by technology

A problem with such stackable chairs having a rack disposed below the seating surface is that, once the rack is attached to the chair, the chair becomes relatively “non-stackable.” This is because the racks prevent each chair from closely nesting with an identical chair.
Because of the relative “non-stackability”of such chairs, the cost of shipping large quantities of such chairs in bulk is unduly large.
However, such slip-on wire book racks are typically retained loosely within a chair, so that the book racks tend to rattle.
Also, such slip-on wire book racks can be easily removed from chairs by mischievous students, thereby resulting in safety issues.

Embodiment Construction

[0024]The following discussion describes in detail one embodiment of the invention and several variations of that embodiment. This discussion should not be construed, however, as limiting the invention to those particular embodiments. Practitioners skilled in the art will recognize numerous other embodiments as well.

[0025]In one aspect of the invention, the invention is a stackable chair 10 comprising a seating surface 12, at least three legs 14 and a rack attachment member 16 attached to each of the legs 14. This aspect of the invention is illustrated in FIGS. 1-4.

[0026]The seating surface 12 is typically disposed in an approximately horizontal orientation. In the embodiment illustrated in the drawings, the seating surface 12 is integral with a back member 18. In such an embodiment, it is typical that the seating surface 12 and the back member 18 are made from a plastic material.

[0027]The at least three legs 14 are disposed generally vertically below the seating surface 12. However...

Abstract

A stackable chair has a seating surface, at least three legs and a rack attachment member attached to each of the legs. Each rack attachment member has a leg attachment portion attached to one of the legs and a rack attachment portion capable of reversibly securing a portion of a rack to one of the legs below the seating surface. Typically, the invention further includes a rack, such as a thick rack, disposed below the seating surface and generally parallel thereto. The rack having a plurality of radiating prongs, each of the prongs being attached to a rack attachment portion of one of the rack attachment members.

Description

FIELD OF THE INVENTION[0001]This invention relates generally to lightweight chairs and, more specifically, to stackable lightweight chairs.BACKGROUND OF THE INVENTION[0002]Stackable lightweight chairs have become very popular. Increasingly popular are stackable lightweight chairs having a rack, such as a book rack, disposed below the seating surface of the chair. Such a stackable chair with a rack disposed below the seating surface is illustrated in FIG. 13.[0003]A problem with such stackable chairs having a rack disposed below the seating surface is that, once the rack is attached to the chair, the chair becomes relatively “non-stackable.” This is because the racks prevent each chair from closely nesting with an identical chair. This problem is illustrated in FIG. 14.[0004]The relatively “non-stackable” nature of stackable chairs having a rack disposed below the seating surface is especially important to those responsible for shipping large quantities of such stackable chairs in bu...
