The invention involves the personal air conditioning of individual workstations in an open office space layout. The individual workstation's air is supplied by a major air plenum located under a horizontal surface of the workstation. The conditioned air is directed by a smaller self-contained air terminal located under a floor representing a larger major air plenum or chamber. The conditioned air is supplied to the individual workstations at or near the atmospheric pressure. The multiple of smaller air terminals are the movers of the conditioned air by way of driving fans installed therein and activated as the need arises. The conditioned air is moved from the smaller air terminals by flexible air tubes to the air plenum mounted under the desk surface. A person situated at the workstation can control the direction of air emanating from the front of the personalized air outlet plenum toward the person in multiple directions. Further, the person can also control the volume of the personal air by being able to divert some of the air away from the person through a wall in the desk or through a wall of a room partition to an adjoining space.

A personal distribution terminal is designed to provide a self-contained free standing or stand-alone enclosure for easy placement wherever office personnel require convenient access to building services. The placement of this enclosure may be in the vicinity of a standard desk or other workstations or where people congregate. The occupant of the nearby workstation has control over personal air flow for personal comfort. The enclosure is so constructed to also provide space control by displacement ventilation for the surrounding area to provide greater indoor air quality and reduce energy consumption. Incorporated into the enclosure are other services in the modem office, such as electric, both constant or interruptible, communication terminals and internet connections. The use of this terminal eliminates floor and wall grilles for better esthetics, and easier, more economical installation and housekeeping. The result of this inventive concept is substantial energy savings based on individual control of personal air supply and displacement ventilation permitting overall higher operating temperatures. The overall result is a simple installation of the terminal for easy and less expensive construction and ease of relocation.

A displacement ventilation system is located above a floor having an air plenum below the floor but above the concrete slab. A displacement ventilation workstation structure is located above the floor and thereby above the air plenum. An air fan is located below the floor and delivers air into flexible air ducts and from there into rigid upstanding air ducts. From there the conditioned air is delivered into rigid upstanding air ducts structure that is located under a workstation surface and has a front outlet that is controllable by a person sitting at the workstation. The upstanding duct has a lateral air opening or outlet which is opposite the direction of where air is delivered to the duct structure under the surface of the workstation. The outlet opening supplies the majority of conditioned air and is thereby delivered into the atmosphere of the work space at a very low velocity and at a point which is below the work surface of the workstation. This system does not create any uncomfortable air streams and air turbulences.

A personalized air conditioning/displacement ventilation system is located above a floor having an air plenum below the floor but above the concrete slab. A displacement ventilation stand-alone air chamber is located above the floor and thereby delivers air above the air plenum. The air chamber has a frontal outlet and a lateral air outlet into the ambient atmosphere. Within the stand-alone chamber the air is being displaced in various amounts to various outlets. The stand-alone unit can be placed wherever it is needed or desired in many locations in a wide open work place as a retrofit.

A chin support adapted to be used on a patient undergoing a prolonged dental procedure. The chin support consists of a bib which is draped around a frontal area of a patient. The bib is made of a relatively stiff material and has two vertical slots therein. A clamping mechanism is located in each of the slots and each has an upstanding rod attached to it. Each of the upstanding rods is attached to a chin support. When a predetermined position has been reached with the chin support with respect to an open jaw of the patient, each of the clamping mechanisms is tightened to keep the chin support in an adjusted position to enhance and maintain the comfort of the patient.

Disclosed is a cable installation in an office layout having a raised floor forming a plenum having air conditioned air charged therein. The conditioned air is lead through the floor by way of flexible tubes that are guided to the various office stations located above the floor. Wherever needed, the flexible tubes are connected above the floor and below the floor to rigid tubes that are located in the replaceable tiles in the raised floor. This installation requires that various cables also must be installed. It has been found that the most convenient way to accomplish this is to lead the cables through the flexible tubes to wherever they are needed. The cables are conveniently located under the floor. The rigid tube installed in the tile of the floor has a lower rigid extension. An opening is placed laterally into the rigid tube, a special plate is placed to cover the opening including a sealing element.
