Abstract
A plug device for use in repairing an opening in a damaged wall portion of a double-walled structure. The device is composed of two elongated, preferably cylindrical, sections formed integrally in end-to-end relationship, and includes an adhesive backer. The device is inserted into the opening and secured at its distal end against the inner surface of the opposing wall. Upon severance and removal of the proximal section of the device, the surface of the intact member within the opening provides a rigid, fixed backing for patch material such as plaster, spackle or the like.
Claims13
A method of blocking an opening in a damaged wall portion of a double-walled structure having a front wall and a rear wall spaced therefrom, comprising the steps of:
- inserting through said opening a cylindrical plug comprising a first section and a second section formed integrally in end-to-end relationship;
- severing said second section from said first section and removing said second section;
- and
- depositing settable patch material on the outer surface end of said first section to fill the space between said surface and the surface of said front wall.
A plug device for blocking an opening in a damaged wall portion of a double-walled structure having a front wall and a rear wall spaced therefrom, comprising:
- a preformed elongated member, made from an expanded plastic foam material, insertable into said opening and including a first section and a second section formed integrally in end-to-end relationship;
- and
- a boundary surface between said first and second sections defined by an annular grooved region surrounding a central core defining a weakened recessed area for facilitating severance of said first and second section upon application of a sufficient force.
A plug device for blocking an opening in a damaged wall portion of a double-walled structure having a front wall and a rear wall spaced therefrom, comprising:
- a preformed elongate member insertable into said opening and including a first section and a second section formed integrally in end-to-end relationship;
- a boundary surface between said first and second sections defined by a cut-through annular region surrounding a central core for facilitating severance of said first and said second section upon application of a sufficient force;
- and
- pressure-sensitive adhesive on the distal end of said first section for securing said section to said rear wall.
The plug device for blocking an opening in a damaged wall portion of a double-walled structure having a front wall and a rear wall spaced therefrom, comprising:
- a preformed elongate member insertable into said opening and including a first section and a second section formed integrally in end-to-end relationship;
- a boundary surface between said first and second sections defined by a cut-through annular region surrounding a central core for facilitating severance of said first and said second section upon application of a sufficient force;
- and
- double-sided tape, having a thickness of at least 1/32 inch, on the distal end of said first section for securing said first section to said rear wall.
