More specifically, this disclosure, its aspects and embodiments, are not limited to the specific material types, components, methods, or other examples disclosed herein. Many additional material types, components, methods, and procedures known in the art are contemplated for use with particular implementations from this disclosure. Accordingly, for example, although particular implementations are disclosed, such implementations and implementing components may comprise any components, models, types, materials, versions, quantities, and/or the like as is known in the art for such systems and implementing components, consistent with the intended operation.


The present disclosure is related to a base 100 for a chair 10 or some other seating device, such as a stool 20. Throughout this disclosure, when a chair 10 or a stool 20 is referenced, it is to be understood that any other seating device may be implemented with the base 100 with the same effect. The base 100 comprises a platform 102, at least one support 104 extending up from the platform 102, at least one void 106 extending through the platform 102, and at least one bowl 108 configured to sit within the at least one void 106.


The platform 102 has a top surface 110 and a bottom surface 112 opposite the top surface 110. The platform 102 may be planar, where the top surface 110 is a flat surface. The bottom surface 112 may also be flat and the top surface 110 and the bottom surface 112 may be parallel to each other. In some embodiments, the platform 102 is formed from sheet metal, and thus is a more substantial and continuous surface than is provided by a network of bars or other materials. The top surface 110 of the platform 102 may be textured to increase traction on the top surface 110. This improves the safety of the base 100 by decreasing the likelihood that a user of the chair 10 might slip when supporting some of the user's weight on the base 100. Similarly, the top surface 110 may have a plurality of perforations 114 or holes extending through the platform that are distinct from the voids 106. The perforations 114 are small enough that the perforations 114 increase traction on the top surface 110 without interfering with the function of the platform 102 as a footrest or chair base. For example, the perforations may have a maximum dimension within a plane parallel with the top surface 110 that is less than or equal to one inch. In some embodiments, this maximum dimension may be less than or equal to ¾ inch or ½ inch.


The top surface 110 of the platform 102 may be bordered by a plurality of sides 116. The sides 116 may be straight, and thus the platform 102 may be polygonal, with straight sides 116 bordering the top surface 110. In some embodiments, the sides 116 are not straight, having a curved path instead. The platform 102 may even by circular, with one curved side. Each of the sides 116 may extend downward from the top surface 110 past the bottom surface 112. In some embodiments, each of the sides 116 additionally extends inward toward a center 118 of the platform 102 such that, at the sides 116 of the platform 102, the platform 102 curves or extends down and underneath the platform 102. The platform 102 may be mounted on wheels 120 that are configured to mobilize the chair base 100. The wheels 120 may be configured to allow the base 100 to move in any direction.


The support 104 may be at least one support 104 or a plurality of supports 104. The support 104 extends up from the top surface 110 of the platform 102 and is configured to support the seat 12 of a chair 10 above the platform 102. In some embodiments, the supports 104 originate within the platform 102. The support 104 may have any cross-sectional shape. In some embodiments, the cross section of the support 104 is an elongated rectangle while in other embodiments, the cross section of the support 104 is circular or any other shape.


The seat 12 may be mounted on a post 14. The post 14 may be directly attached to the supports 104 or may be movably coupled to the supports 104 through a height adjustment mechanism 16. The height adjustment mechanism 16 may be movably or slidably coupled to the post 14 and is configured to control a height of the seat 12 above the platform 102. Thus, the post 14 and the seat 12 may be raised and lowered using the height adjustment mechanism 16. An example of a height adjustment mechanism 16 can be found in U.S. patent application Ser. No. 18/128,014, filed on Mar. 29, 2023, by Ronald B. Johnson, the disclosure of which is hereby incorporated herein by this reference. The platform 102 may have a central aperture 122 extending through the center 118 of the platform 102. The central aperture 122 is configured to allow the post 14 to pass through the platform 102. Thus, the central aperture 122 is sized and shaped so that the post 14 fits through the central aperture 122. This allows the seat 12 to have a greater range of motion between a maximum height above the platform 102 and a minimum height above the platform 102 because the platform 102 does not interfere with the post 14 as the seat 12 moves to lower heights above the platform 102.


As mentioned above, the at least one void 106 extends through the platform 102 and the at least one bowl 108 is configured to sit within the at least one void 106. The at least one bowl 108 is thus sized and shaped to fit into the void 106. Additionally, the bowl 108 is sized to store tools or parts that may be used by the person sitting in the chair. For example, the bowl 108 may be used to hold a collection of screws or a hand tool. In some embodiments, the void 106 is a plurality of voids 106 and the bowl 108 is a plurality of bowls 108. The plurality of voids 106 may be positioned equidistantly from the center 118 of the platform 102. The voids 106 may be polygonal or any other shape. Similarly, the bowls 108 may be polygonal or any other shape. The voids 106 and the bowls 108 are not necessarily the same shape in a particular embodiment, though they may be. The voids 106 are distinct from the perforations 114 described above both in purpose and size. While the perforations 114 are not configured to receive a bowl 108, the voids 106 are configured to receive a bowl 108. Similarly, while the perforations 114 are small, in many embodiments having a maximum dimension smaller than one inch, the voids 106 are much larger and are configured to allow a majority of the bowl 108 to pass through the platform 102 as described in more detail below.


The bowl 108 may have a depth that is less than a width of the bowl 108, but that is more than half a width of the bowl 108. This limits the likelihood of items within the bowl 108 falling out of the bowl 108 while still keeping the items within the bowl 108 easily accessible by hand. Each of the plurality of bowls 108 has a lip 124 that is configured to engage with a rim 126 of a corresponding void 106. The lip 124 thus is configured to restrict the bowl 108 from entirely passing through the platform 102. Instead, a majority of the bowl 108 passes through the platform 102, and then the lip 124 catches on the rim 126 and the bowl 108 sits within the void 106 as mentioned above. Each bowl 108 may be removable from the corresponding void 106.


In some embodiments, the total number or quantity of each of the sides 116 of the platform 102, the supports 104, the voids 106, and/or the bowls 108 may be equal. For example, a total number of the sides 116 of the platform 102, a total number of the supports 104 on the base 100, and a total number of the voids 106 extending through the platform 102 may be equal. The total number of a component refers to the quantity of that component present in a particular embodiment without excluding any of that component from the count. In some embodiments, there are five sides 116 of the platform 102, five supports 104 on the base 100, and five voids 106 extending through the platform 102.


It will be understood that implementations of a chair base are not limited to the specific assemblies, devices and components disclosed in this document, as virtually any assemblies, devices and components consistent with the intended operation of a chair base may be used. Accordingly, for example, although particular chair bases, and other assemblies, devices and components are disclosed, such may include any shape, size, style, type, model, version, class, measurement, concentration, material, weight, quantity, and/or the like consistent with the intended operation of chair bases. Implementations are not limited to uses of any specific assemblies, devices and components; provided that the assemblies, devices and components selected are consistent with the intended operation of a chair base.


Accordingly, the components defining any chair base may be formed of any of many different types of materials or combinations thereof that can readily be formed into shaped objects provided that the materials selected are consistent with the intended operation of a chair base.

In instances where a part, component, feature, or element is governed by a standard, rule, code, or other requirement, the part may be made in accordance with, and to comply under such standard, rule, code, or other requirement.


Various chair bases may be manufactured using conventional procedures as added to and improved upon through the procedures described here. Some components defining a chair base may be manufactured simultaneously and integrally joined with one another, while other components may be purchased pre-manufactured or manufactured separately and then assembled with the integral components. Various implementations may be manufactured using conventional procedures as added to and improved upon through the procedures described here.


Accordingly, manufacture of these components separately or simultaneously may involve extrusion, pultrusion, vacuum forming, injection molding, blow molding, resin transfer molding, casting, forging, cold rolling, milling, drilling, reaming, turning, grinding, stamping, cutting, bending, welding, soldering, hardening, riveting, punching, plating, and/or the like. If any of the components are manufactured separately, they may then be coupled with one another in any manner, such as with adhesive, a weld, a fastener (e.g. a bolt, a nut, a screw, a nail, a rivet, a pin, and/or the like), wiring, any combination thereof, and/or the like for example, depending on, among other considerations, the particular material forming the components.


It will be understood that methods for manufacturing or assembling chair bases are not limited to the specific order of steps as disclosed in this document. Any steps or sequence of steps of the assembly of a chair base indicated herein are given as examples of possible steps or sequence of steps and not as limitations, since various assembly processes and sequences of steps may be used to assemble chair bases.
