Abstract
Abstract A device includes a shaft having first and second ends and a length between the first and second ends sufficient to span an airspace between first and second wallboards mounted on a wall framework. First and second mountings are provided for securing a separately supplied patch to the first end of the shaft and the second end of the shaft to the second wallboard in order to support the patch in a hole in the first wallboard. A method of patching a hole in a wallboard includes providing a device as described above, securing a patch to the first end of the shaft and securing the second end of the shaft to the second wallboard so that the patch is in the hole in the first wallboard.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
108 words
A device, comprising: a shaft having first and second ends and a length between the first and second ends sufficient to span an airspace between first and second wallboards that are mounted on a wall framework so that they are separated by an airspace of predetermined size; first mounting means for securing a separately supplied patch to the first end of the shaft; and second mounting means for securing the second end of the shaft to the second wallboard in order to support the patch in a hole in the first wallboard; wherein the first and second mounting means are integrally attached to the shaft in one-piece construction.
Claim 2
Independent Claim
108 words
A device, comprising: a shaft having first and second ends and a length between the first and second ends sufficient to span an airspace between first and second wallboards that are mounted on a wall framework so that they are separated by an airspace of predetermined size; first mounting means for securing a separately supplied patch to the first end of the shaft; and second mounting means for securing the second end of the shaft to the second wallboard in order to support the patch in a hole in the first wallboard; wherein the first and second mounting means are integrally attached to the shaft in one-piece construction.
Claim 3
Dependent Claim
31 words
A device as recited in claim 1 wherein at least one of the first and second mounting means is configured so that it can be screwed into the patch or wallboard.
Claim 4
Dependent Claim
34 words
A device as recited in claim 1 wherein at least one of the first and second mounting means is configured so that it can be driven into the patch or wallboard like a nail.
Claim 5
Dependent Claim
16 words
A device as recited in claim 1, wherein the device is composed of a metal alloy.
Claim 6
Dependent Claim
16 words
A device as recited in claim 1, wherein the shaft is composed of a thermoplastic material.
Claim 7
Dependent Claim
41 words
A device as recited in claim 1, wherein the first mounting means includes a screw member attached to the first end of the shaft and the second mounting means includes a nail member attached to the second end of the shaft.
Claim 8
Dependent Claim
58 words
A device as recited in claim 1, further comprising: a first radially extending portion of the shaft located adjacent the first end of the shaft, which first radially extending portion extends radially outwardly more than the first mounting means in order to abut the patch when the patch is mounted on the shaft with the first mounting means.
Claim 9
Dependent Claim
58 words
A device as recited in claim 7, further comprising: a second radially extending portion of the shaft located adjacent the second end of the shaft, which second radially extending portion extends radially outwardly more than the second mounting means in order to abut the wallboard when the shaft is mounted on the wallboard with the second mounting means.
Claim 10
Dependent Claim
15 words
A device as recited in claim 1, wherein the length of the shaft is adjustable.
Claim 11
Independent Claim
125 words
A device, comprising: a shaft having first and second ends, a first radially extending portion at the first end, a second radially extending portion located at the second end, and a length between the first and second ends sufficient to span an airspace between first and second wallboards mounted on a wall framework; means defining a screw member integrally attached in one-piece construction to a first end of the shaft for securing a separately supplied patch to the shaft; and means defining a nail member integrally attached in one-piece construction to a second end of the shaft for securing the second end of the shaft to the first wallboard so that the patch is supported in a hole to be patched in the first wallboard.
Claim 12
Independent Claim
125 words
A device, comprising: a shaft having first and second ends, a first radially extending portion at the first end, a second radially extending portion located at the second end, and a length between the first and second ends sufficient to span an airspace between first and second wallboards mounted on a wall framework; means defining a screw member integrally attached in one-piece construction to a first end of the shaft for securing a separately supplied patch to the shaft; and means defining a nail member integrally attached in one-piece construction to a second end of the shaft for securing the second end of the shaft to the first wallboard so that the patch is supported in a hole to be patched in the first wallboard.
