The present invention generally relates to a chair with an adjustable height seat. More particularly, the present invention relates to an adjustable height seat where the consumer may determine the height of the seat by including or not including one or more components to adjust the height of the seat top past the height of the seat legs.
Tables are in wide use by consumers in a variety of applications and settings, including in private and commercial settings. Consumers may purchase seats of different heights according to their needs and wishes, although most consumers are currently limited by the seat heights offered by manufacturers. The desired height of a seat may vary depending upon a number of factors, including, but not limited to, the space the seat will be used in, the height of the consumers using the seat, the purpose of the seat, the style of seat and/or the style of the environment in which the seat will be used. Because seats are so commonly used, it is frequently the case that a seat may be purchased for one use or setting, but then the consumer may wish to use the same seat for a different use or in a different setting. In changing the purpose or setting of the seat, it is likely that the consumer may wish to change the height of the seat. Additionally, a change in ownership of the seat or a number of other factors, including a change in décor, may cause the consumer to wish to change the seat height.
Typically if a consumer wishes to have a seat of a new height, the consumer must cut an existing seat to a smaller height or must get a new seat of the new desired height. A typical consumer cannot raise the height of a seat his or herself. Furthermore, a typical consumer is unable to easily lower the height of the seat by cutting the seat legs. This is especially true in light of the variety of seat constructions which involve ornamental or complicated bases.
In order to reduce the cost to consumers and to increase flexibility in interior and exterior decorating, it may be desirable to have a seat that allows the consumer to easily adjust the height of the seat, either lower or greater, as they wish.
A preferred embodiment of the present invention provides a chair with an adjustable height seat. The height may be adjusted by the inclusion or exclusion of a set of components that may be fastened to the legs or base of the chair to adjust the height of the chair. The components may be embodied as the leg extenders, an apron, or some other form that fits into the structure of the chair. The components may be easily attached to, or removed from, the chair as the consumer desires in order to adjust the height of the chair.
The chair top 110 includes a lower support element 114, a top support element 116, a support connector 115 and cross-supports 118. The lower support element 114 is connected to the support connectors 115, which in turn are connected to the top support element 116. The cross-supports 118 are preferably connected to the top support element 116.
The chair top insert elements 112 are adapted to fit into both the leg extender insert apertures 135 and the leg insert apertures 125, and may be secured using leg extender fastener aperture 137 or leg fastener aperture 127. The chair top 110 is thus able to be positioned at a vertical height either directly above the chair legs 120 or directly above the leg extenders 130, which are in turn positioned at a vertical height above the chair legs 120.
In operation, in order to position the adjustable height chair with the chair top at a first height or vertical position relative to the surface on which the chair is positioned, the user proceeds as follows. First, the chair top insert elements 112 of the chair top 110 are introduced into the leg insert apertures 125 of each of the legs 120. Next, the chair top insert elements 112 are fastened into the leg insert apertures 125 of the legs 120 using the leg fastener apertures 127.
Alternatively, if the user desires to position the chair top 110 at a second, greater height relative to the surface on which the chair is positioned, the user proceeds as follows. First, the chair top insert elements 112 may be inserted instead into the leg extender insert apertures 135, and the chair top insert elements 112 may be fastened to the leg extenders 130 using the leg extender fastener apertures 137. Next, the leg extender insert elements 132 may in turn be inserted into the leg insert apertures 125. Further, the leg extenders 130 may in turn be fastened to the legs 120 using the leg fastener apertures 127. Consequently, the vertical height of the chair top 110 relative to the supporting surface on which the adjustable height chair is positioned is increased by the height of the leg extenders 130.

Additionally, more that one set of leg extenders may be employed. In a first example, the chair 100 may be shipped with two sets of leg extenders. The first set of legs extenders may have a first length, such as 4 inches for example, and the second set of leg extenders may have a second length such as 6 inches for example. In this embodiment, if the user desires the height of the chair top to be increased upward by 4 inches, the user installs the first set of leg extenders. Conversely, if the user desires the height of the chair top to be increased upward by 6 inches, the user installs the second set of leg extenders.
In a second example of an embodiment that is shipped with two sets of leg extenders, the leg extenders may cooperate to provide a third, even greater height adjustment for the chair top. For example, the first set of leg extenders may have a height of 4 inches and the second set of leg extenders may have a height of 2 inches. If the user desires the height of the chair top to be increased by 2 inches, then the user installs only the second set of leg extenders. However, if the user desires the height of the chair top to be increased by 4 inches, then the user installs only the first set of leg extenders. In addition, if the user desires the height of the chair top to be increased by 6 inches, then the user first installs the first set of leg extenders, and then installs the second set of leg extenders on top of the first set of leg extenders.

Alternatively, the leg set and/or the leg extenders may not contain any fasteners. For example, the insert elements may simply be introduced into insert apertures and may remain there under the force or gravity or friction.
Further, although the chair top 110 in the exemplary chair in
The seat 310 is preferably connected to the chair top 110. For example, the seat 310 may be connected to the top support element 116 or cross-supports 118 of the chair top 110. The chair back 320 is preferably also connected to either the chair top 110 directly or to the seat 310.
In operation, the chair base including the chair top 110, chair legs 120, and leg extenders 130 is assembled as described above. Then, the seat 310 is positioned on top of the cross-supports 118 of the chair top 110 and the seat 310 is bolted to the cross supports 118 by placing bolts through the bolt holes 330 and matching bolt holes on the seat 310. The chair back 320 may then be directly connected to the chair top 110.
Alternatively, the chair back 320 may be connected to the seat 310 prior to connecting the seat 310 to the chair top 110.
In operation, if the user desires to position the chair top at a first vertical height, then the user positions the chair top fastener apertures in proximity to the leg fastener apertures 422 and then passes fasteners through both the chair top fastener apertures and the leg fastener apertures 422 to fasten the chair top 410 to the legs 420.
Alternatively, if the user desires to position the chair top at a second, greater vertical height, the user positions the chair top fastener apertures in proximity to the apron-table top fastener apertures 432 and then passes fasteners through both the chair top fasteners apertures and the apron-table top fastener apertures 432 to fasten the chair top 410 to the apron 430. The user then positions the apron-leg fastener apertures in proximity to the leg fastener apertures 422 and then passes fasteners through both the apron-leg fastener apertures and leg fastener apertures 422 to fasten the apron 430 to the legs 420.

The seat 310 is preferably connected to the chair top 410. For example, the seat 310 may be connected to the cross-supports 418 of the chair top 410. The chair back 320 is preferably also connected to either the chair top 410 directly or to the seat 310.
In operation, the chair base including the chair top 410, chair legs 420, and leg extenders 430 is assembled as described above. Then, the seat 310 is positioned on top of the cross-supports 418 of the chair top 410 and the seat 310 is bolted to the cross supports 418 by placing bolts through the bolt holes 330 and matching bolt holes on the seat 310. The chair back 320 may then be directly connected to the chair top 410.
Alternatively, the chair back 320 may be connected to the seat 310 prior to connecting the seat 310 to the chair top 410.
The chair top 710 is adapted to connect to either 1) the removable apron 730, 2) the leg extenders 750, or 3) the chair legs 720, depending upon the desired height for the seat of the chair. Further, when the chair top 710 is connected to the removable apron, the removable apron 730 may be connected to either the leg extenders or directly to the chair legs, depending upon the desired height. Further configuration options are illustrated below.

In any configuration, a set and chair back similar to the seat 310 and chair back 320 of
Although an embodiment above have been presented using a chair seat that is fixed to the chair top, the chair seat may alternatively include a swivel mechanism to allow the chair seat and/or chair back to swivel relative to the chair top.
Alternatively, although an embodiment above presented a design with a single apron, multiple aprons may be employed. Similar to the employment of multiple leg extenders, the multiple aprons may be stackable so that more than one is used at the same time and/or may replace one another and be used one at a time.
Also, in certain embodiments the seat, the apron, the legs, and the leg extensions, and/or other elements may be composed of any rigid material such as steel, wood, or plastic.
Alternatively, certain embodiments of the present invention may be implemented on other furniture articles such as tables, chairs, bars, cabinets, or dressers, ottomans, and plant stands.
