. This invention relates a i ii iforciiig and supporting device adapted for use in construction and repair work, and liiafs fdr its piifiiary obsurface of holes inwau earded/resonate and other building materials ih 'buildihgs.
Another primary object of this irifvention is to hold and retain in plaee' the mater-inseminated inthe holes to repair the holes and to form a base for the materials and become a permanent part of the surface worked on.
Another object of this invention is to .provide an inexpensive device "which "can be easily 'pb'sitioned on the internal surface of a wall or the like and which WiIFcIinga'nd clar'iip orito the internal surface of the wall -to form a base for plastering material used to fill in the hole-or'openmg.
A primary feature of this invention resides in the provision of a plurality ofperfOrated-metaI disks, joined together by suitable securingmeans, the disks being adapted to cover one another for insertion in the holes, and after insertion, to spread out into extended position to be clamped securely on the internal surface of the wall opening or other type of opening so as to form a base for repair material.
These and ancillary objects and other meritorious features are attained by this invention, a preferred embodiment of which is set forth in the following description and illustrated in the accompanying drawings, wherein:
Figure 1 is a fragmentary side elevational view of a wall, illustrating an opening therein, this invention being clamped on the internal surface of the wall in alignment with the opening for retaining the repair material utilized to repair the opening;
Figure 2 is a vertical sectional view taken on the transverse plane of line 2-2 of Figure 1;
Figure 3 is a cross sectional view of this invention, showing the disks in flush engagement with the others;
Figure 4 is a front elevational view of this invention, showing the disks in covering alignment;
Figure 5 is a front elevational view of this invention, showing the disks in open and extended position;
Figure 6 is a side elevational view;
Figure 7 is a view in perspective of the clamp provided to engage the external surface of the wall and to retain the disks in position on the internal surface of the wall even with the hole; and
Figure 8 is a'transversesecnona1 view "through one "of the disks, illustrating "the "s'auc'er or oupshape of the disk's.
Referring now more particularly to the drawings, wherein similar characters 'of reference designates corresponding parts throughout, this invention, generally designated by"the-'character reference ID, comprises a plurality of circular metal-disks, 1:2, M-a'nd 16. coursefithe size and number of the disks is 't'o'be "determined by actual working"'c'onditions fans the "s'ize=off'the opening desired to be repaired, with respect :to Figure 1 of the drawings. "The disKs-are-suitabIy perforated, as at l 8 in evenspacenfent*throughout, and are adapted to cover one another for insertio'n'i'n a hole Orbp'ening. For this-purpose, the disks are preferably formed with a convex outer surface and a concave under surface, the disks being saucer-shaped. The disks are juxtaposed when inserted through the "openirig fand are adapted to be extendedbr'fanne'dout when positioned on the inner surface 'of th'e wall. The disks are preferably pivoted together 'off 'center by any suitable means, such as a bolt 20 and a conventional nut 22, the bolt being placed through the off-center openings or apertures l8 formed in the disks. For the purpose of maintaining at least two of the disks in juxtaposition, and establishing the axially aligned position thereof an arm 40 is formed integrally with the periphery of one of the disks, preferably the middle disk I2. The arm is bent back upon itself and terminates in an end extension 42 engageable with the upper surface of the disk l4. Of course, the arm 40 may be secured by any means, such as welding or the like, to the periphery of any of the disks and serve to engage and receive the companion disks and maintain the set of disks in juxtaposition.
Thus, with reference to Figure 1 of the drawings, the juxtapositioned disks are inserted through the opening 30 in a wall 32, and after insertion the bolt 20 is twisted clockwise or counter-clockwise until the three disks fall into an extended position, as seen in Figure 1. A clamp 24 comprising a medial body portion 26 having a central aperture 28 therein is adapted to engage the external surface of the wall and to support the disks in an extended position on the internal surface of the wall in alignment with the opening. The clamp 24 has a pair of laterally extending wings 34 and 36 which are spaced from the plane of the body portion 26 by means of forwardly extending parallel connecting portions 38. The wings 34 and 36 are adapted to seat in rectangular grooves 48 formed in the external surface of th wall, as seen in Figure 1 of the drawings. Thus, the filler material placed in the opening and received by the disks will completely repair the opening and the material may be positioned over the extending wings of the clamp, so that all of the repair structure is hidden from view, to avoid any marring of the appearance of the wall.
Of course, it is to be apparent that the disks can be made in all sizes and from all types of material, depending upon the size of the opening and the type of repair material to be utilized. For example, in repairing an opening in an automobile or metal body, the disks can be fashioned as shown in Figure 8, wherein the disks are formed from a substantially imperforate piece of material, having a single aperture l8 formed therein. The single aperture 18 in each disk is adapted to register with the other apertures and to receive suitable securing means. It is to;be noted that the single aperture I8 is disposed a substantial distance from the center point'of the .disks.
Thus, it can be seen that the base forming disks, in association with the anchoring and locking member 24,- serve as a base for supporting repair and lining material. The anchoring of the disks to the internal surface of the wall can be easily performed .and the placement of the disks in alignment with the opening furnishes an extremely effective means for holding building or repair material in place.
However, since many other purposes and objects of this invention will become apparent to those skilled in the art upon a perusal of the foregoing description in view of the accompanying drawings, it is to be understood that certain changes may be effected thereon as coming within the spirit of the invention and within the scope of the appended claims.
Having described the invention, what claimed as new is:
1. A device for backing repair material placed in a hole in a wall comprising a series of perforated superposed disks, a nut equipped bolt extending through said disks eccentrically thereof and pivotally securing the same together for relative swinging movement into axial alignment for passing through said hole, and out of axial alignment to overlap one side of the wall around said hole, and a bar slidably mounted intermediate its ends on said bolt for movement axially thereof at one side of the series of disks for engagement with the other side of said wall adjacent opposite sides of the hole, said series of disks and said bar being relatively adjustable laterally by tightening of said bolt to clampingly engage the first and second-named sides of the wall respectively.
2. A device according to claim 1, wherein said bar'is provided with end wings ofiset laterally therefrom toward the series of disks for countersinking in grooves formed in said other side of REFERENCES CITED The following references are of record in-the file of this patent:
