Filed Aug. 13, B55, Ser. No. sensor 9 Claims. or. Ziit) Another object of the invention is to provide a floor Y which can be maintained level in spite of the fact that the base under it, such as another floor or subfloor, or a concrete base, may not be level itself.
Another object of the invention is to provide a floor which will distribute the weight evenly over the base thus permitting concentrated loads without injury to the floor itself or to the base.
With these and further object in view as will be apparent from the ensuing description, the invention consists of the constructions described but without any purpose to limit the constructions to those actually depicted.
Referring to the drawings, FIGURE 1 shows a perspective view of my floor with parts broken away to more thoroughly illustrate the construction.
FIGURE 2 is a view in perspective of one of the floor panels.
FIGURE 3 is a view taken along the lines 3-3 of FIG. 1.
FIGURE 4 is an exploded view of the T-bar supports and the slotted head and the dajustable pedestals.
FIGURE 5- is a perspective View of the resilient clip or holding means by which the floor panels are held to the T-bar supports.
Referring to the drawings, I have shown a panel floor indicated by the numeral 1. Separate panels are indicated by the numeral 2. Each panel may comprise a series of tiles, or parquet, or cork units or wooden units. Each of the panels may be solid or may comprise for decorative purposes a number of smaller units assembled within the confines of the periphery of the main panel. These smaller units are illustrated by numerals 3. See FEGURE 2.
The main panels 2 as illustrated have a surface comprising the smaller units 3 held in place by a rim 4 of a metallic border member 5 which has a plane surface, free of any ribs or grooves which may be in interengaging relation with the border members of the adjacent panels. Lying within the metallic border member S is an upper metallic flat member 6 and spaced therefrom a lower metallic flat member 7. These may be spaced apart by a honeycomb construction '7' which may consist of metal, paper, or plastic or some other suitable material which makes the panels 2 strong but very light. Thus, the panels have a high loading capacity-to-weight ratio. Such honeycomb construction is usual in airplane manufacture.
Each panel 2 is provided with spring clips 7" which are adapted to contact with the edge of the tlat upper member 8 of a T-bar support construction having its middle member, or web, 9 projecting downwardly.
Some of the T-bar supports may be cut on its ends on a slant as indicated at it) so that the middle member 29 may be inserted in the slots 11 of a slotted head 12 having a downwardly proiecting portion 13 around whi h is adapted to rotate a pipe 14 which forms a central stern of the adjustable pedestal support. The central pipe or stem 14 is screw threaded as indicated at I5; the screw threads at 15 cooperating with the screw threads 16 in a footing 17 which may be provided with screw holes 18 which permit the footing 17 to be permanently attached as by screws or bolts (not shown) to a base member 1%. The base member 19 may be another floor upon which my pedestal panel floor is adapted to be supported.
As before indicated, the panel sections 2 may be of solid metal or any desired construction, such as the one illustrated, but they are held in detachable resilient relationship by clips 7" to the horizontal members 8 of the T-bar supports. The central webs 9 hold the slotted head 12 against rotation and by rotating the stern which comprises the pipe 14, the head 12 may be raised or lowered by reason of the screw threaded engagement of the stem 14 with the footing 17.
Thus each of the adjustable pedestals may be elongated or made shorter to make the main floor 1 even though there are irregularities in the base 19.
It will be noted that there are a series of T-bar supports which are relatively long, that is to say, they rest on at least three of the slotted heads of the pedestals. This gives strength to the construction and permits distribution of any concentrated load on the fioor 1 because more than two pedestals are engaged by the series of T-bar supports of relatively great length. There are spacer supports of shorter length as indicated at 2t. The spacer supports hold the relatively long supports indicated by the numeral 21 in FIG. 1 in properly spaced relationship. The slanted construction it} of the ends of the short supports 2%? enable the construction to be readily asembled.
Obviously portions of panels 2 may be removed or may be cut out to any desired configuration to permit passage of electrical wires, pipes, or other equipment to the machinery which is being supported on the pedestal panel floor.
Que of the features of the floor is the detachability of the panels 2. These panels can be removed, for example, by placins a suction cup on the floor and raising the suction cup which will raise the panel 2 and release the spring clips 7 from engagement with the flat sections 8 of the T-bar supports.
Each panel may be individually removed for easy access to the space beneath or the life of a panel may be increased greatly by changing the panel positions. There is often a permanent perimeter construction to square the room and insure complete fieiiibility of panels. Ramps of stationary or folding type are often desirable.
While I have shown and described one embodiment of my invention, I desire that I be limited only by the scope of the appended claims and the showing of the prior art.
