Abstract: An armrest apparatus and chair including one or more armrest apparatuses are disclosed. Each armrest apparatus includes an armrest member attached to at least one chair component. The armrest member has a first aperture and a second aperture. A first plate is positioned above the armrest member. The first plate has a longitudinal slot that is transverse to the first and second apertures. An armrest cover is attached to the first plate. A resilient device is positioned between the first plate and the armrest cover or between the first plate and the armrest member. The resilient device has a first hole sized and configured to receive the first member and a second hole sized and configured to receive the second member. A first member extends through the first aperture, first hole and the longitudinal slot and a second member extends through the second aperture, second hole and the longitudinal slot.

Abstract: A method of assembling a chair includes providing a first chair component composed of a first polymeric material and a second chair component composed of a second polymeric material. An adhesive is positioned on or in the first chair component. The adhesive is composed of a third polymeric material and at least one ferromagnetic susceptor. The second chair component is positioned in engagement with the adhesive and adjacent to the first chair component. A magnetic field or electromagnetic waves are applied to the adhesive to activate the adhesive. A force is also applied to at least one of the first chair component and the second chair component to press the first chair component and the second chair component. A chair is also provided that includes the first and second chair components and the adhesive.

Abstract: A method of laser welding chair components together is provided. The method includes selecting at least one first chair component comprised of a first polymeric material that is at least substantially translucent to a laser and selecting at least one second chair component comprised of a second polymeric material that is opaque to the laser such that the one or more second chair components will absorb at least a portion of the heat or energy provided by the laser. The one or more first chair components are laser welded to the one or more second chair components. A chair is also provided that includes a first component composed of polymeric material laser welded to a second component composed of polymeric material.

Abstract: A height adjustment mechanism is disclosed that includes a pedestal height variability mechanism. The pedestal height variability mechanism includes a first member and a biasing mechanism. The biasing mechanism is configured to hold the first member in a first position. The first member has a first end and a second end opposite the first end. The biasing mechanism has a first portion attached to the first member adjacent the first end of the first member. The biasing mechanism also has a second portion attached to the first member adjacent to the second end of the first member. Preferably, a second member is also provided that is moveably attached to the first member. The second member may be configured such that movement of the second member actuates height adjustment of a chair.

Abstract: A mechanical support arm for holding lamps, flat screen monitors or other equipment which comprises a base member and two links joined by pivoting joints and held in position by friction in the joints. The amount of friction required to hold the equipment in position is reduced by the use of spring-assisted counterbalances that compensate for the majority of the weight. The novel aspects of the invention include the design of the pivots, which are linked rings able to rotate about axles disposed at the pivot points, and the manner in which the springs are attached to the pivot points to reduce the amount of force that need be exerted on the arm to place the object being supported in the desired position.

Abstract: A wall spine assembly for a modular office system comprises a plurality of individual panel assemblies. Each of the panel assemblies includes a vertical support structure and mechanically affixed lower panels in a rigid box-beam structure. Facing panels are removably attached to support brackets mounted on the vertical supports. A cavity exists between the facing panels and vertical supports to permit the lay-in of cabling through the office system. A crown member is provided on the top of the vertical support and is adapted to receive brackets for the mounting of accessories above a desk or other work surface attached to the panel. The panels, and especially the crown, permit the mounting of office components such as shelves, storage cabinets, lighting fixtures and the like anywhere along the horizontal length of the wall. A horizontally telescoping vertical end post is also provided.
