Louver configuration for welding apparatus
First Claim
1. A louver assembly, said assembly comprising an enclosure, a plurality of louvers formed in the enclosure and positioned parallel to each other, the plurality of louvers having substantially the same configuration, each of the louvers having a front edge on a front portion, a rear edge on a rear portion, and an intermediate edge located between the front edge and the rear edge, adjacent louvers being spaced apart from each other such that a line extending along the front portion from the front edge to the intermediate edge of a lower louver extends to and intersects the rear edge of an upper louver and the intermediate edge of a first louver is displaced outwardly from a line extending between the front edge and the rear edge of an adjacent louver.

Abstract
A welding apparatus having specially designed louvers that are used to cover vent openings in the enclosure and contain the components of the welding apparatus. The louvers have a common side profile and have a configuration with a rear portion that is preferably horizontal and a front portion that angles downwardly, forming a front edge. An intermediate edge is formed by the front portion and the rear portion meeting at an angle. The intermediate edge is displaced away from a straight line drawn between the front edge and the rear edge. The configuration and spacing between adjacent louvers is designed such that a standard test probe cannot be inserted through the space between any two adjacent louvers.

- 1. A louver assembly, said assembly comprising an enclosure, a plurality of louvers formed in the enclosure and positioned parallel to each other, the plurality of louvers having substantially the same configuration, each of the louvers having a front edge on a front portion, a rear edge on a rear portion, and an intermediate edge located between the front edge and the rear edge, adjacent louvers being spaced apart from each other such that a line extending along the front portion from the front edge to the intermediate edge of a lower louver extends to and intersects the rear edge of an upper louver and the intermediate edge of a first louver is displaced outwardly from a line extending between the front edge and the rear edge of an adjacent louver.
- 5. A welding apparatus comprising an enclosure having a front panel and a rear panel and a base to enclose therein an interior area to contain components for the welding apparatus, a louver assembly formed in at least the rear panel, the louver assembly comprising a plurality of louvers positioned side by side parallel to each other, the louvers having substantially the same cross-sectional profile, each of the louvers having a front edge, a rear edge and an intermediate edge located between the front edge and the rear edge, wherein a front portion of each louver has a generally uniform cross-section that inclines from the front edge to the intermediate edge and a rear portion of each louver has a cross-section generally horizontal to the welding apparatus and tapered from the intermediate edge to the rear edge, adjacent louvers being spaced apart from each other to prevent a probe of predetermined diameter from passing the rear edge of any one of the louvers.
- 11. A vent assembly to provide air flow into an enclosed heat generating apparatus comprising a series of louvers each louver having a front non-tapered portion with a front edge and a rear tapered portion with a rear edge separated by an intermediate edge, the front portion being at an angle to the rear portion with the intermediate edge being a point of deflection, each louver having a substantially identical cross-section and arranged such that an object having a predetermined width inserted between two louvers cannot pass past the rear portion of any louver.
-
19. A vent assembly to provide air flow into an enclosed heat generating apparatus comprising:
-
a series of louvers, each louver having a front portion and a rear portion separated by an intermediate edge, the front portion being at an angle to the rear portion with the intermediate edge being a point of deflection, each louver having a substaintially identical cross-section and arranged such that an object having a predetermined width inserted between two louvers cannot pass past the rear portion of any louver while maintaining a line of sight through the series of louvers between adjacent louvers;
a welder having two sets of the series of louvers, one set positioned on an air intake and one set positioned on an air discharge, the welder constructed without screening on either the air intake or the air discharge; and
wherein the louvers of each set are connected to one another through a single center post.

20. A vent assembly to provide air flow into an enclosed heat generating apparatus comprising:
-
a series of louvers, each louver having a front portion and a rear portion separated by an intermediate edge, the front portion being at an angle to the rear portion with the intermediate edge being a point of deflection wherein the intermediate edge is displaced outwardly from a line connecting a front edge and a rear edge of an adjacent louver, each louver having a substantially identical cross-section and arranged such that an object having a predetermined width inserted between two louvers cannot pass past the rear portion of any louver;
wherein the vent assembly is incorporated into a welder having two sets of louvers, one set positioned on an air intake and one set positioned on an air discharge, the welder constructed without screening on either the air intake or the air discharge; and
wherein the set of louvers is constructed of a one-piece assembly wherein a lower half of the assembly includes the series of louvers terminating at a midpoint of the assembly. - View Dependent Claims (21)
