Chrastek, deceased Filed Feb. 11, 1964, Ser. No. 343,991 3 Claims. (Cl. 52-126) This invention relates to floor structures and more particularly to a structure for fabricating a paneled floor in elevated spaced relation to a suitable supporting surface.
It is the primary object of the present invention to provide an improved floor structure.
Still another object of the invention is to provide a structure for readily fabricating a paneled floor in elevated spaced relation to a supporting surface.
An additional object of the present invention is to provide an elevated panel floor structure which is capable of supporting substantial loads while at the same time being relatively inexpensive and easily assembled.
An additional object of the present invention is to provide an elevated paneled floor structure for supporting portable instrumented installations (e.g. data processing installations), which floor structure provides suitable means for accommodating the cables and other instrumentalities employed with such installations in readily accessible locations.
Other objects and advantages of the present invention will become apparent from the following detailed description when considered in conjunction with the accompanying drawing wherein:
FIGURE 1 is a perspective view of a portion of an elevated paneled floor structure constructed in accordance with the present invention and with portions of the structure broken away to more clearly illustrate the invention;
FIGURE 2 is an enlarged exploded view of a preferred embodiment of the supporting structure employed in the elevated paneled floor depicted in FIGURE 1;
FIGURE 3 is an enlarged cross sectional view taken along the line 33 in FIGURE 1; and
FIGURE 4 is an enlarged cross sectional view similar to FIGURE 3 but taken along the line 4-4 in FIG- URE 1.
In general, the present invention is directed to an improved elevated floor structure which is capable of supporting portable instrumented installations such as a typical data processing installation. In accordance with the provisions of the present invention, a structurally strong supporting floor is provided for supporting a variety of forms of electronic equipment without obstructing the working area around the equipment by necessitating the distribution of supply cables, control lines, conduits and the like over the surface of the floor. In this connection, means are provided for housing the cables and other instrumentalities employed with the portable equipment so that these instrumentalities are appropriately confined in readily accessible regions. That is, rather than having a confusing and troublesome array of supply cables, control lines, conduits and the like randomly distributed beneath the elevated floor structure, these instrumentalities are uniformly distributed in readily accessible regions provided by the supporting structure for the floor. If desired, these housings when appropriately sealed can be employed as air ducts for either a ventilation or cooling system.
As shown in the accompanyig drawing and particularly in FIGURE 1, a preferred embodiment of the floor structure includes a plurality of vertically adjustable support pedestals that are adapted to be selectively positioned about a suitable supporting surface 13 over which the elevated floor is to be constructed. These vertically adjustable support pedestals 11) function to support elongated floor panel mounting members 11 and transverse spacer and mounting members 11a. As a result, a stable and uniformly arranged base structure is provided whereon a plurality of floor panels 12 are peripherally supported to provide a structurally strong floor situated in elevated spaced relation to the supporting surface 13.
Referring now in detail to the preferred embodiment of the floor structure illustrated in the drawing, each of the vertically adjustable support pedestals 10 includes a number of cooperative components. These components facilitate the selective placement of the pedestals 10 on and about the supporting surface 13 and the joining of the floor panel mounting members 11 and 11a to the pedestals.
More particularly, each of the pedestals 11} is provided with a base plate 15 that is adapted to be secured to the supporting surface 13 by suitable fasteners (not shown) after the pedestal is appropriately positioned thereon. Secured to and extending upwardly from the base plate 15 is an adjusting screw 16 that mates with and is encompassed by at least a portion of a tubular pedestal shaft 17. The tubular pedestal shaft 17 has a nut 18 secured to the lower extremity thereof so that the nut is rotatable relative to the shaft and threadably engages the adjusting screw 16. Rotation of the nut 18 (ie by the action of a wrench or other suitable tool) results in the nut being selectively advanced upwardly or downwardly. In a conventional manner, a locking nut 19 is provided on the adjusting screw 16 to limit the travel of the nut 18 and the associated shaft 17.
As is obvious from a consideration of the drawing, the selective upward or downward advance of the nut 18 is transmitted to the shaft 17 and to a supporting plate 21 that is fastened to the upper extremity of the shaft (e.g. by welding or the like). However, the position of the locking nut 19 limits the downward travel of the nut 18 and, accordingly, of the shaft 17 and supporting plate 21 that are secured thereto. During the fabrication of an elevated floor structure, the locking nut 19 is appropriately positioned and the nut 18 is advanced into abutting fixed engagement therewith to yield the desired level of the base structure for the elevated floor.
As shown in FIGS. 1 and 2, the elongated floor panel mounting members 11 are preferably designed to be mounted on at least a pair of the vertically adjustable support pedestals 10. The transverse spacer and mounting members 11a can either be secured to and supported between only the members 11 or can also be supported by' one or more pedestals 10, the construction being dictated by the dimensions of the spanned areas and the load to be supported. In any event, the final configuration provides a structurally stable and uniformly arranged base structure for peripherally supporting the floor panels 12.
More particularly, each of the illustrated floor panel mounting members 11 is shown as being removably secured to the supporting plates 21 of a plurality of the support pedestals 10. In this connection, each of the elongated floor panel mounting members 11 is in the form of a trough or channel 22 that is defined by a base plate 23 and a pair of side walls 24 that extend upwardly from the base plate and mate with suitable covers 25, as hereinafter described in detail. Preferably, the width of the base plate 23 is equal to or greater than the corresponding dimension of the support plate 21 provided by each of the pedestals 10. With this arrangement, the floor panel mounting members 11 are readily mountable on the support plates 21. To facilitate this mounting, the mating portions of the base plate 23 and the support plates 21 are apertured to receive suitable fasteners 26,
although welding of the base plate to the support plates can be effected where desired in lieu of the fasteners 26.
The supporting structure for a completed elevated floor also generally includes a number of the spacer and mounting members 1111 that define troughs or channels 22a. In this connection, whether the transverse spacer and mounting members 11a are or are not independently supported on one or more pedestals in a manner similar to the members 11, each of these transverse members is coupled to and supported at the ends thereof by adjacent ones of the elongated members 11. To effect this, corresponding portions of aligned side walls 24 of adjacent pairs of the members 11 are provided with rectangular slots or openings 27 at appropriately spaced intervals (FIG. 1), and the opposite ends of the trough forming side walls 24a of the transverse members 11a are provided with flanges 28. The length of the members 11a is selected so that the flanged ends of each fits within the slots 27 and so that the flanges 28 engage the slot defining portions of the side walls 24 (FIG. 3). Thereafter, the covers 25 are positioned over the members 11, and covers 2511 are fitted over the transverse members 11a so that a plurality of enclosed and communicating channels 22 and 22a are provided thereby for receiving supply cables, control lines, conduits and the like.
The covers 25 for the members 11 include a top plate 31 and a pair of mounting brackets 32 that are designed to mate with and fit between the side walls 24. The brackets 32, which extend downwardly from the top plate 31, have an inverted L shaped configuration and are spaced apart a distance such that the side walls 24 are urged apart when engaged by the covers, and the covers are thereby effectively snapped into place. The covers 25a for the transverse members 11a correspond substantially to those for the continuous mounting members 11. However, these covers do not extend the entire length of the transverse members 11a so that their cooperative positioning adjacent the edges of the covers 25 on the elongated members 11 is facilitated. However, both the covers 25 and 25a have a width somewhat greater than the width of the members 11 and 11a so that a substantial supporting surface is provided for the floor panels 12.
The construction of an elevated floor in accordance with the present invention is initiated by the suitable placement of a plurality of the adjustable pedestals about the supporting surface 13. After the pedestals are properly arrayed about the surface 13, they are removably secured in place and the level for the base structure is achieved by the selective adjustment of the nuts 18 and 19.
Thereafter, the necessary number of elongated panel mounting members 11 are positioned on the base plates of selected ones of the pedestals and are removably se cured to these base plates by the fasteners 26 in accordance with conventional techniques. Upon completion of this operation, the necessary number of spacer and mounting members 11a are joined to and supported by the transverse members 11 so that a structurally stable base is provided for the floor panels 12. When the covers 25 and 25a are positioned on the members 11 and and 11a, the channels 22 and 22a formed by these members are fully enclosed and provide a plurality of communicating passageways within the base structure itself. The construction of the floor is completed by the placement and joining of the floor panels which are preferably designed to be peripherally supported by the base structure as shown in FIGURE 1.
The floor panels 12 which may be formed of any suitable material and of any suitable dimensions (i.e. consistent with a high and properly distributed load carrying ability) provide the actual supporting surface for the equipment or installation with which the floor is to be used. In this connection, when the equipment and devices constituting the particular installation are properly located on the floor structure, appropriate ones of the floor panels 12 are removed to allow access to the covers 25 and 25a of appropriate ones of the panel mounting members 11 and 11a. These covers are then removed and the supply cables, control lines and conduits associated with the equipment are disposed within the channels 22 and 22a defined by these panels mounting members and guided thereby to the appropriate sources or outlets.
When this has been completed, the covers 25 and 25a are again placed on the members 11 and 11a. The floor panels are then repositioned after suitable apertures are provided both in the covers and in the panels to accommodate the passage of the cables and the like from the equipment into the channels. With this arrangement for conveniently housing the supply cables, control lines and conduits associated with the equipment, these instrumentalities can be readily located and easily identified, and the usual confusing and troublesome array of these members beneath the elevated floor is eliminated.
It should be understood that the foregoing detailed description of one preferred embodiment of the elevated floor structure is simply illustrative of the invention. Various modifications in the structure could be devised by one skilled in the art without departing from the invention. For example, the covers 25 and 25a can be constructed, joined to the members 11 and 11a, and suitably gasketed so that the channels 22 and 22a are essentially airtight. With this type of arrangement it is possible to either ventilate or circulate air through selected ones of the mounting members thereby eliminating the need for certain of the control lines usually employed with various portable instrumented installations. These and other modifications of the structure described above clearly fall within the scope of the following claims.
