CONVERTIBLE STOOL
A convertible stool is interchangeable between a utility function which has a seat movable up and down and has casters as feet at the end of legs connected with the seat through an upstanding member. In a second use, the casters are replaced by feet to give stability to the chair on a floor or base. As such, the second use can be a furniture type use.

This application claims priority to U.S. patent application Ser. No. 11/041,140, filed on Jan. 21, 2005, and which claims priority to U.S. Provisional Application No. 60/629,123, filed Nov. 17, 2004, the contents of which are incorporated herein in their entirety.
BACKGROUND1. Field
This disclosure relates to a stool which has multiple purposes.
2. General Background
It is desirable to have stools that can perform different functions and purposes and as such can have different characteristics and uses.
SUMMARYThis disclosure relates to a stool that serves a utility function and in this sense has a seat which can move upwardly and downwardly as required by a user. The user can operate a pneumatic mechanism to make the seat settle at a desired height so that utility functions can be performed. The seat is preferably mounted on a single pneumatic post and there are legs splayed out from the post and casters at the end of the legs, which act as movable feet for this stool. The stool acts as a utility stool with maneuverability as required by a user.
In a different sense, the casters are replaceable and stationary feet are put in location on the legs. This permits the stool to constitute furniture-like function that is stationary on its base. The stool can be raised or lowered as necessary on the central spindle or pillar.
Other objects and features of the disclosure will become apparent from the following detailed description and accompanying drawings.

As can be seen when the stationary feet are used the outside surface of these feet meets with a relatively harmonious interface with the outside surface of the ends of the legs so that there is an aesthetically satisfying appearance achieved when the stationary feet are in place and stool is to be used as a furniture item.
The top of the feet at the interface with the spindle is in mating engagement with bottom of the interface 23 so as to have tight fitting contact which is aesthetically pleasing. The tool can engage around the spindle 25 and be urged like a fork with tines that fit to either side of the spindle and between the ends of the legs and the top of the feet so that the feet can thereby be wedged from their engaged position in the hole. To have the feet with the spindle-leg configuration and conformation provides an effective mechanism for easy exchange of the feet as desired. The tool is illustrated in
The stool can be packaged as a set or kit with the wedging tool so that the appropriate feet can be used as desired by the consumer at the appropriate time.
In this manner there is provided a stool that is convertible between multi-functional purposes. When the feet are in place, the stool can provide an effective furniture item which can be used for instance in a bar, and in this sense, the seat 10 can be raised or lowered as necessary to a particular counter height. Alternatively, the stool in its fixed relationship can be a useful furniture item in a home, such as in a kitchen or the like.
As such there is provided a kit for a multi-functional convertible stool which comprises a saddle seat adjustable in height relative to a base on which the seat stands. There are multiple legs arranged to support the seat, the legs being connected with the seat, the legs having extremities and the legs having selectively removable feet. There are feet being casters and feet being stationary feet. The stool is convertible such that in one configuration with casters on the legs, the seat is movable on a base or floor and in a different configuration with stationary feet, the seat is relatively stationary on the base or floor.
The saddle seat is movable on a pneumatically mounted pillar which extends between the legs and the seat, thereby to vary the height of the saddle seat relative to the floor.
A method of converting a stool which is multifunctional as a utility stool in a first mode including the steps of applying removable casters to feet for a stool such that the stool can be moved on casters that facilitate rolling movement on a floor so as to permit movement around a workspace without the need for a user to get off a seat.
The seat is permitted to be raised or lowered according to the suitable height for use as a utility function around the workspace.
When the casters are removed and removable non-movable feet are applied in a second mode the stool acts as a furniture item which is not rollable on the floor. The legs including the non-movable feet are such that the stool can be located in a fixed relationship relative to a floor except if physically dragged in a non-rolling manner to a different location.
While the apparatus and method have been described in terms of what are presently considered to be the most practical and preferred embodiments, it is to be understood that the disclosure need not be limited to the disclosed embodiments. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structures.
Claims
1. A method of converting a stool which is multifunctional as a utility stool in a first mode and a furniture item in a second mode including the steps of:
- applying removable casters to feet for a stool such that the stool can be moved on casters that facilitate rolling movement on a floor so as to permit movement around a workspace without the need for a user to get off a seat;
- permitting the seat to be raised or lowered according to the suitable height for use as a utility function around the workspace;
- removing the casters; and
- applying removable non-movable feet such that in the second mode the stool acts as the furniture item which is not rollable on the floor, the legs including the non-movable feet being such that the stool can be located in a fixed relationship relative to a floor except if physically dragged in a non-rolling manner to a different location.
2. The method as claimed in claim 1, including permitting moving the seat relatively vertically and the movement being on a central pillar extending from the base of the seat to the legs.
3. The method as claimed in claim 2, wherein the stool includes multiple legs, the multiple legs being splayed radially from the cental pillar, the multiple legs each having a bottom face, the bottom face having a hole permitting applying the removable casters or removable non-movable feet; and
- wherein both the casters and non-movable feet have a top face, the top face having a spindle, wherein the top face of the casters or non-movable feet are located oppositely the bottom face of the legs and wherein the spindle enters and enters tight fitting contact with the hole in the bottom face of the legs securing the casters or non-movable feet with the legs.
4. The method as claimed in claim 2, including raising and lowering of the seat and through the pillar, the pillar including a pneumatic member.
5. The method of claim 1 further comprising utilizing a tool to facilitate easy removal of the casters of non-movable feet.
6. The method of claim 5 further comprising engaging a spindle on a top face of the caster or non-movable feet to facilitate removal.
