Description

Patented Sept. 5, 1933 UNITED STATES 1,925,271 COMPOSITE noon CONSTRUCTION Roy G. Miller, Farmingdale, N. Y., assignor to The A vlation Patent and Research Corporation, a corporation of New York Application March 31, 1932. Serial No. 602,249

2 Claims. 15449) This invention relates in general to floor con-' stfuction and has for its objectthe provision of a compoflte double wall floor which will have the characteristics of durability resiliency and safeguard against slipp e of users of the floor.

A further object is the provision of a simple method of assembling the floor, a simple means of introduction of the resilient material and of formation of the tread from such resilient material.

With the foregoing. and other objects in view, the invention consists in the combination of parts and in the details of construction hereinafter set forthin the following specification and appended claims, certain embodiments thereof being illustrated in the accompanying drawing, in which:

Figure 1 is a top plan view of the assembled floor partly broken away.

Figure 2 is a view in section taken of the floor showing the two rigid layers and the intermediate resilient material prior to the expansion thereof.

Figure 3 is a view in section taken along line 3-3 of Figure 1.

Referring more particularly to the drawing, it will be seen that I employ two sheets 1 and 2 of rigid materiaL'such as metal, between which I introduce resilient material 3, such as sponge rubber, vulcanized rubber or any suitable filling substance. Each of the rigid sheets 1 and 2 are provided with a plurality of perforations, such as shown at 4 and 5, respectively.

The manner of assembly may vary, but I prefer to lay the two sheets with the resilient substance between them, as shown in Figure 2, and to subsequently bring about the expansion of the resilient substance while maintaining the same 0 distance between the two rigid sheets. Under such expansion, the substance protrudes through the'apertures until the construction assumes the form shown in Figure 3.

The illustration of the number, size and shape of the apertures is merely arbitrary as is the showing of the exact alignment of the upper with the lower apertures and consequently may be varied to suit convenience or preference.

The expansion of-the resilient material, especially if spongy or vulcanized rubber is used, may

be brought about by any of the well lmown combe made of light weight metal and such weight supplemented only by that of the expanded rubber makes it especially adapted for use in airplanes of the passenger transport type. The provision of apertures in both the upper and lower floor sheets allows the formation by the expansion of the rubber of safety non-slip treads 6 for the user and similar treads '7 which reduce the possibility of slippage of the portable floor itself. The treads '7 further provide an additional cushioning for the user of the floor.

Another possible modification of the invention is to use rubber or the like which has been moulded into the shape, as shown in Figure 3, and to place the floor sheets so that the treads 6 and '1 would be aligned with apertures 4 and 5 and protrude therethrough.

I claim:

1. In, a composite floor construction, a pair of rigid sheets spaced apart and each of which is provided with a plurality of apertures arranged in both, and a mass of rubber filling the space between said sheets, said rubber being provided with protuberances extending through said apertures and beyond the upper and lower planes of the remainder of the floor assembly.

2. In a composite floor construction, a pair of rigid sheets spaced apart and each of which is provided with a plurality of apertures arranged in both, and a mass of rubber filling the space between said sheets, said rubber being expanded to decrease its density and to form protuberances extending through said apertures to form treads.

The floor may be made more or less permanent 55 or may be a portable one. In the case of a portable floor, mat or runway, the rigid sheetsmay
