Abstract
An entry port including at least one cylinder with a lip on the attachment portion surrounding each hole in a plate. The rim surrounding each hole is rolled over a lip on a corresponding cylinder to secure each cylinder to the plate to form the entry port. Each cylinder preferably has a flared circumference on the portion away from the attachment to the plate to allow a boot to be clamped on each cylinder.
Claims9
An entry port adapted for attachment to a structure, the entry port comprising:
- a cylinder having an inwardly protruding lip on an attachment portion of the cylinder, wherein the cylinder includes a flared circumference on a distal portion, and
- a plate having a rim defining a hole with a rim lip that overlaps the lip of the cylinder wherein the rim lip is bent over the lip of the cylinder to secure the cylinder to the plate.
A method of manufacturing an entry port comprising steps of:
- forming a plate with a hole and an inwardly tapered rim lip surrounding the hole;
- forming a cylinder with an inwardly protruding lip on an attachment portion of the cylinder, wherein the step of forming the cylinder includes forming a flared circumference on a distal portion of the cylinder;
- placing the attachment portion of the cylinder around the inwardly tapered rim lip of the plate;
- and
- rolling the inwardly tapered rim lip around the lip of the cylinder to form a rolled rim lip to secure the cylinder to the plate.
A method of manufacturing an entry port comprising steps of:
- forming a plate with numerous holes having an inwardly tapered rim lip surrounding each hole;
- forming cylinders with an inwardly protruding lip on an attachment portion of each cylinder;
- placing the attachment portion of each cylinder around each inwardly tapered rim lip of the plate;
- and
- rolling each inwardly tapered rim lip around the corresponding lip of each cylinder to form a rolled rim lip to secure each cylinder to the plate.
An entry port adapted for attachment to a structure, the entry port consisting of only a cylinder and a plate:
- the cylinder having an inwardly protruding lip on an attachment portion of the cylinder and the plate having a rim defining a hole with a rim lip that overlaps the lip of the cylinder wherein the rim lip is a circumference of the hole and the rim lip is rolled over the lip of the cylinder to secure the cylinder to the plate.
An entry port adapted for attachment to a structure, the entry port comprising:
- a cylinder having an inwardly protruding lip on an attachment portion of the cylinder and a plate having a rim defining a hole with a rim lip that overlaps the lip of the cylinder to secure the cylinder to the plate, wherein the rim lip forms a continuous curvilinear circle and wherein the cylinder includes a flared circumference on a distal portion.
