Abstract

A hole renovator assembly completely covers both sides of a hole, one of which is inaccessible, in a surface and comprises a base with two 'winged' sections, one of which 2 is attached to a rod 1 and the other 3 free to rotate around it so that in the closed position they can pass through a hole of a lesser diameter than that of the maximum length of either section and that when set in the open position form a solid area greater than that of the hole. A top 4 is placed onto the rod and against the surface surrounding the hole followed by a securing device which when tightened results in compression that spread the base and top uniformily outwards to make contact with the surfaces surrounding each side of the hole along the length of their circumference. <IMAGE>

Description

HOLE RENOVATOR ASSEMBLY This invention relates to a hole renovator assembly.
It is possible to repair a hole that has one inaccessible side, call it 'the inside', by covering it with a material on 'the outside' and securing it to the surfaces surrounding the hole by various means i.e. adhesion. weld, etc.
However. there are eonditions under which such a method may be unsuitable: where the pressure generated from 'the inside' could not be reasonably overcome by the pressure needed to retain the material on 'the outside' during, or after repair; where a fluid. liquid, gas, etc. on 'the inside' could react dangerously with the method used to secure the material, heat, flame, acid, etc; where the power required for such means of securing was not readily availible; etc.
According to the present invention there is provided a hole renovator assembly comprising the base (a sub-assembly), a rod, a top, and a method of of securing the assembly together.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Figure 1 shows the base sub-assembly in the closed position; Figure 2 shows the base sub-assembly in the open position; Figure 3 shows a cross section of the base sub-assemly; Figure 4 shows the top; Figure 5 shows a cross section of the top; Figure 5 shows a cross section of the assembly in operation.
Assuming that the hole to be renovated is inaccessible from one side then referring to the drawing the base sub-assembly comprises a rod 1 and two 'winged' sections, one of which 2 is attached to the rod and the other 3 free to rotate around it so that, as shown in Fig 1, in the closed position they will pass through a hole of a lesser diameter than that of the maximum length of either section.
The base sub-assembly in the closed position, as shown in Fig 1, is inserted through to the inaccessible side of the hole and, with the rod 1, and therefor the bottom 'winged' section 2, retained in place by, for example the hand or some mechanical means, the top 'winged' section 3 is rotated by, for example finger control of a suitibly positioned stud on the top of the 'winged' section or by some other manual or mechanical means, until the two 'winged' sections interlock to form a solid area as shown in Fig 2. With the rod 1 still retained in place, the top 4 shown in Fig 4 is placed onto the rod 1 and pushed down onto the surface surrounding the hole. The assembly is centalised to ensure that the hole is completely covered and is secured in place by, for example a washer and nut or similar means as shown in Fig 5.
Both the top and base are so shaped and made of such a material that when they are compressed by the method of securing they spread uniformily outwards to make contact with the surfaces surounding each side of the hole along the length of their circumference.

Claims (2)

1. A hole renovator assembly comprising: a base sub-assembly comprising of a rod and two 'winged' sections, one of which is attached to the rod and the other free to rotate around it so that in the closed position they will pass through a hole, being inaccessible from one side, of a lesser diameter than that of the maximum length of either section and when set in the open position form a solid area greater than that of the hole: a top, again of greater area than the hole, that is placed onto the rod and against the surface surrounding the hole: a means of securing the assembly so that the resultant compression spread the base and top uniformily outwards to make contact with the surfaces surrounding each side of the hole along the length of their circumference.
2. A hole renovator assembly substantially as described herein with reference to Figures 1-8 of the accompanying drawing.
