26:9 BY dZrmes W. Hoson 4 TTOQNEY United States Patent Ofice Patented June 24, 1969 US. Cl. 312--209 13 Claims ABSTRACT OF THE DISCLOSURE A laboratory service core of modular construction in which a generally rectangular cabinet is provided with a recess in the upper surface thereof. Disposed within the recess are like sets of utility supply facilities symmetrically located so that access may be had thereto from opposite sides of the cabinet. A vertically movable shelf has a first position covering the recess and a second position upwardly spaced therefrom to permit access.
I This invention relates to science furniture, and more particularly to a laboratory service .core of modular construction containing utility service facilities arranged for access from opposite sides of the construction.
In the design and layout of laboratory facilities it is often necessary to provide accessibility to utility services, such as water, electricity and gas, with sufficient working space thereabout to carry on whatever work is to be done in using such facilities. A typical example is in a classroom laboratory where numerous people find it necessary to have access to such utility supply means and such access must be supplied under efficient and economical conditions.
In designing laboratories in the past, it has been common to provide large and cumbersome service core facilities with large counter areas immediately adjacent the utility service means, such constructions normally being arranged to permit only limited access to the facilities by large groups of people. Consequently, and particularly in classroom usage, the number of students who can use the facilities is small, or else the laboratory must be of tramendous size in order to provide sufficient service facilities for a reasonable number of people, The usual plan in laboratory design is rigid, since the service facil ities are fixed in permanent places throughout the room, thus making it impossible to redesign or relocate the facilities without complete reconstruction of the laboratory. In addition, the usual laboratory service facility is open at all times; that is, the utility service means are always accessible for unauthorized usage thereof.
The construction in which this invention is embodied comprises, generally, a laboratory service core which is accessible from either side and which is provided with like sets of utility facilities symmetrically disposed in a recess in the cabinet so that access may be had from either side of the cabinet. A shelf member is movably supported in the cabinet and in one position covers the utility supply recess and in another position extends upwardly therefrom and forms a convenient shelf surface thereabove for temporary storage. All utility supply conduit and piping means extend within and through the cabinet so that the cabinet may be easily connected to base supply means or may be connected to other like laboratory service cores in end-to-end relation.
With such a construction, the design and layout of laboratory facilities is greatly enhanced, leading to great versatility in arangement of furniture and use thereof by large numbers of people. The modular nature of the service core permits a wide variety of groupings and arrangements around which people will have ready access to the utility facilities. Since there are like sets of facilities at opposite ends of the core recess, the same service core can be used by two or more people, operating from op posite sides of the cabinet in which the facilities are mounted, thus a greater amount of flexibility and accessibility is available in a service core of extremely simple and economical construction easily assembled and movable from place to place for redesign of the furniture grouping.
These and other advantages will become more apparent from the following description and drawing in which:
FIGURE 1 is a schematic view of a typical classroom layout, utilizing a laboratory service core embodying the invention.
FIGURE 2 is an enlarged elevational view of the laboratory service core illustrated in FIGURE 1, with parts broken away and in section to illustrate the position of the various parts.

FIGURE 5 is a perspective view of a portion of the laboratory service core illustrated in FIGURES 1 through 4.
FIGURE 6 is a cross sectional view similar to FIG- URE 4, illustrating a modification of the laboratory service core.
FIGURE 7 is another cross sectional view similar to FIGURE 4, illustrating another modification of the laboratory service core.
Referring more particularly to the drawings, FIGURE 1 best illustrates the ease with which classroom furniture may be designed and located using a laboratory service core embodying the invention. It is to be understood at the outset that the invention is not restricted to classroom use but may be used in any laboratory facility. For ease in description and understanding, the furniture is described with respect to classroom use.
A laboratory service core, illustrated generally by the numeral 10 in FIGURE 1, may form the basis for a unit of usage wherein desks or other work surfaces, as illustrated generally by the numeral 12, are symmetrically disposed on opposite sides of the service core 10. Stools, chairs or the like 14 indicate the location of the people utilizing the service core 10 and indicate that the service core is available from opposite sides and from opposite ends, thus permitting each person to do his own work without interference from the other. It will be apparent that the grouping illustrated in FIGURE 1 may be repeated along a horizontal line, as viewed in the drawing, or may be easily located in other designs depending upon the space available in the laboratory and the number of students using such facilities. As will become hereinafter more particularly apparent, the ease with which the regrouping may be done without extensive modification to the utility supply means provides great versatility in the arrangement possibilities.
Referring next to FIGURES 24, the laboratory service core 10 is a generally rectangular cabinet having side walls 16, end walls 18 and top surface portions 20 joining the side walls 16 and end walls 18. Inwardly spaced from the end walls 18 and extending downwardly for a portion of the length thereof are intermediate walls 22, joined at a point below the top surface portions 20 by a support member 24. Intermediate walls 22 and support member 24 extend between the side walls 16 and thus form a recess in the upper portion of the cabinet Intermediate walls 22 and support member 24 may be of any suitable Configuration "and are shown for convenience to be a one piece affair formed of sheet metal or the like, suitably anchored beneath the upper surface portions 20.
Disposed in the intermediate walls 22 are like symmetrical sets of utility service supply means. A gas connection, indicated generally by the numeral 26, is disposed in each intermediate wall 22 and on opposite sides of the longitudinal center line'ofthe,cabinet 10. Electrical supply boxes, indicated generally by the numeral 28, are of conventional construction and are mounted in the intermediate walls 22. Pivoted covers 30 may be provided for safety and protection.
Disposed centrally in the support member 24 is a sink 32 having water supply faucets, indicated generally by the numeral 34, on opposite sides thereof. The faucet handles 36 are accessible from opposite side Walls 16.
The supply means for the utility service devices, such as gas jets 26, water faucets 34 and electrical supply means 28, are all contained within the cabinet 10 and below the support member 24. The main drain pipe for the sink 32 is illustrated at 38, connected to the sink 32 by a shorter drain pipe 40. A gas supply pipe 42 is connected to the opposite gas jets 26 by suitable conduits 44, the connections being made in any suitable manner well known in the art. Similarly, an electrical conduit 46 provides connecting means for the outlet boxes 28 by means of upwardly extending conduits 48, connected in the manner well known in the art. Likewise, water supply is provided through a main conduit 50, connected to the two Water faucets 34 by piping 52. It will be apparent that with the utility service supply being simply arranged beneath the support member 24 and extending longitudinally of the cabinet 10, that the cabinet 10 may easily be located adjacent a second, like cabinet with the supply facilities, such as piping 38, 42, 46 and 50, conveniently connected between the end walls or within the end walls 18. Should the laboratory service core 10 be used alone, it is a relatively simple matter to connect the supply piping to the base supply within the building system.
Secured in each of the intermediate walls 22 is a tubular member 54, conveniently located on the longitudinal center line of the cabinet 10. Received within the tubular members 54 are support legs 56 which extend upwardly to a shelf member, indicated generally by the numeral 58. Support legs 56 are secured to the undersurface of the shelf member 58 in any suitable manner, as by flanges 60 and screws 62. The support legs 56 are of sufficient length to extend through the supporting tubes 54 and to permit the shelf member 58 to be raised above the upper surface portions of the cabinet 10, thus allowing unrestricted access to the utility service facilities within the recess formed in the upper surface of the cabinet. When it is desired to restrict access to the utility facilities, the shelf member 58 may be lowered to a position in alignment with the upper surface portions 20, thus closing off access to the facility recess from above. Suitable latch means, such as thumb screws 64, are received through side walls of the tubular members 54 and in selected apertures 65 in the support legs 56. Such apertures 65 may be provided at spaced points along the support legs 56 to provide a number of adjustments for the position of the shelf member 58. By turning the thumb screw 64 into one of the apertures 65, the support legs 56 and the shelf member 58 will be properly secured above the cabinet 10.
Referring next to FIGURE 6, a modification of the cabinet assembly is illustrated and wherein like reference numerals refer to like parts. Where it may be desirable to restrict access to the utility facilities from the sides of the cabinet 10, the shelf member 58 may be provided with downwardly depending side panels 66 of sufficient length to extend between the intermediate walls 22 and of sufficient width to extend between the undersurface of the shelf member 58 and the support member 24.
In this manner, when the shelf member 58 is in its downward position aligned with the upper portions 20 of the cabinet 10, the side panels 66 will completely close the side Walls 16 and the utility supply recess.
Yet another modification is illustrated in FIGURE 7 wherein like reference numerals indicate like parts and wherein the utility supply recess in the cabinet 10 may be completely closed by side panels 68 pivotally mounted by hinges 70 to the support member 24 or to the side panels 16. It will be apparent that when access to the utility supply recess is desired, the side panels 68 may be pivoted outwardly and downwardly, and upon raising the shelf member 58 to an upward position, complete access will be available.
With the like sets of utility supply means, such as gas jets 26, electrical outlets 28 and water supply faucets 34, symmetrically arranged at opposite sides of the supply recess in the cabinet 10, it will be apparent that people on opposite sides of the laboratory service core will have access to the supply facilities from opposite sides of the cabinet 10. At the same time, each person so engaged may carry out his experiments or work without interference from the other and without requiring a wait for utility supply until the other person is finished with his work. The symmetrical arrangement of the utility supply means assures constancy of operation, regardless of which side the experimenter is working on and whether or not he is working with another like service core.
Thus, is will be apparent that an extremely simple laboratory service core of modular design, having utility supply means mounted therein, may be easily used by people from opposite sides of the core. At the same time, such construction provides an extremely versatile piece of furniture for laboratory arrangement. The flexibility of location and usage makes the funiture readily adaptable to classroom usage and allows furniture layout to be readily adapted to the number of students expected to use the equipment.
