The present invention relates generally to furniture systems and, more particularly, to mobile furniture systems suitable for use in various laboratory and other environments.
Furniture systems that can be moved to different locations within a facility are desirable in many applications and environments, such as laboratories, product inspection stations, manufacturing assembly stations, and clean rooms, for example. The mobility of such systems may provide improved flexibility for that environment. Typically, furniture systems include a tabletop, or other generally planar work surface, and may be adapted to support shelving, drawers, dividers, suspended cabinets, tack boards, and various other accessories. During use, furniture systems are typically loaded with laboratory equipment, analytical instrumentation, computers, other types of equipment, and files. In many applications, it may be desirable to provide various utility sources, such as electric, data, gas, fluid and vacuum services, at or near the work surface to facilitate the performance of various tasks.
Due to their size and weight and because they often support any or all of the above listed equipment, typical furniture systems cannot be conveniently and safely relocated. Moving a typical furniture system may require that any equipment, particularly valuable analytical equipment, must be removed from the furniture system and separately moved. And, due to their weight, furniture systems may require at least partial disassembly so that they may be carried to the new location where they may be then reassembled. In addition, even in situations in which some disassembly is undertaken, typical furniture systems may generally require multiple people to carry the disassembled components to the new location before being reassembled.
Alternatively to disassembly of the furniture system, a pallet jack or forklift may be utilized to move the furniture system as a whole. While this may be accomplished without initially unloading the above-identified equipment, utilizing a pallet jack or forklift may be limited to locations which are accessible to these machines because pallet jacks and forklifts are often large bulky machines that require significant space within which to maneuver. As such, space restrictions around the furniture system, such as the presence of other furniture and equipment, may prohibit access via a pallet jack or forklift and thus inhibit convenient relocation of the furniture system. Furthermore, space restrictions within the facility itself, such as, doorways, stairs, and/or elevators, between the current location of the furniture system and the new location for the furniture system may limit use of pallet jacks and forklifts.
Known mobile furniture systems are generally incapable of carrying sufficient weight and are often prone to tipping when being relocated. These furniture systems may include a supporting base including wheels to facilitate relocation of the furniture. However, a small amount of tilt as the result of being moved along an incline or across a threshold which inadvertently catches one wheel, may cause the system to become unstable, and, absent external application of a force to counteract gravity, inadvertent tilting may have catastrophic consequences and may cause injury and/or destruction of equipment.
Accordingly, there is a need for improvements to mobile furniture systems that improve the mobility and stability of such furniture systems while also maintaining or improving their aesthetic appearance.
The present invention overcomes the foregoing and other shortcomings and drawbacks of mobile furniture systems heretofore known for use in suitable various laboratory and other environments. While the invention will be described in connection with certain embodiments, it will be understood that the invention is not limited to these embodiments. On the contrary, the invention includes all alternatives, modifications and equivalents as may be included within the spirit and scope of the present invention.

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the general description of the invention given above, and the detailed description given below, serve to explain the principles of the invention.
By single-sided workstation, it is meant that the mobile furniture system 10 includes a work surface 18 extending from only one side thereof, and without any work surface extending from an opposite side of the mobile furniture system 10. This embodiment is especially suitable for location along a wall or a partition, although the mobile furniture system 10 may stand apart from any other equipment or structure or, alternatively, may be located back-to-back with another mobile furniture system 10.
With continued reference to
Furthermore, in at least the mobile configuration, the mobile furniture system 10 is configured to self-correct its orientation relative to the floor when tilted up to about 10° from its normal orientation. In this regard, the mobile furniture system 10 is configured to revert to its normal orientation, in which all of the rotatable supports 26 are in contact with the ground, if the system 10 is tilted by up to about 10°. In the embodiment shown, by tilted it is meant an orientation of the mobile furniture system 10 in which only two of the rotatable supports 26 are in contact with the ground and the work surface 18 forms an angle with the ground. In this regard, embodiments of the mobile furniture system 10 disclosed herein may pass UL testing and be UL 962 (titled “Household and Commercial Furnishings” and which is incorporated by reference herein in its entirety) tested, listed, and labeled.
In addition, in one embodiment, the mobile furniture system 10 has a stationary configuration in which the feet 28 may contact the ground and generally prohibit or limit lateral movement of the system 10 relative to the floor.
To these and other ends and with continued reference to
With continued reference to
By way of example only, various components of the framework assembly 16 may be formed from sheet metal that has been cut, stamped, bent, welded, or otherwise worked to form the components. Alternatively, it is contemplated that one or more of the components of the framework assembly 16 may comprise extruded aluminum. It will be recognized, however, that the components may alternatively be formed from various other materials and by various other methods, and the invention is not limited to the particular embodiments described herein.
As is described above, the side edge 30 of the work surface 18 is supported by legs 24a, 24b which may each include first and second telescopingly adjustable leg portions 42a, 42b. The relative lengths of leg portions 42a, 42b may be adjusted such that the height of the edge 30 corresponds to the height of the edge 32 above the ground. It will be appreciated that adjusting the leg portions 42a, 42b of each of leg members 24a, 24b may be required where it is desired to have the work surface 18 substantially level in one or both of the stationary configuration and the movable configuration, described below. Further in this regard, in the embodiment shown, the rear edge 32 of the work surface 18 is secured to the vertical frame members 22a, 22b by height-adjustable brackets 50. The brackets 50 may be selectively positioned in any of a plurality of apertures 52 provided on the vertical frame members 22a, 22b.

With reference specifically to
In the retracted position (
When the foot 28 is in the extended position (
Once the mobile furniture system 10 is relocated, in the configuration where each foot 28 is in the retracted position, each of the feet 28 may be extended to lift each wheel 72 from contact with the floor. Once one or more of the feet 28 are extended, so as to lift the respective wheel 72 from contact with the floor, the mobile furniture system 10 may resist lateral movement that would otherwise have moved the mobile furniture system 10 when in the mobile configuration. It will be appreciated that extending each of the feet 28 to lift the respective rotatable supports 26 from the floor may provide a stable, stationary configuration for use on a day-to-day basis.
In the exemplary embodiment shown, and with reference to
Furthermore, while the feet 28 are described herein as being movable with respect to the rotatable support 26, the reverse configuration is also contemplated. That is, the rotatable support 26 may be operatively coupled to the respective frame members 22a, 22b and/or leg members 24a, 24b so as to have an extended position and a retracted position. In the extended position, each rotatable support 26 may contact the floor so that the mobile furniture system 10 is movable. And, when the rotatable support 26 is in the retracted position, the feet 28 are in contact with the floor such that the mobile furniture system 10 resists movement and provides a stable, stationary configuration for day-to-day use.
