Abstract
A battery jar cover having a guide device depending from the bottom thereof and positioned so as to extend about at least predetermined portions of the periphery of the cover and inwardly from the sides thereof. The guide device is shaped so that it extends downwardly from the bottom of the cover a greater degree adjacent the corners and to a lesser degree adjacent the central portion of each side. Thus, the shape of the depending guide varies in length from the corners to the center thereof along each side.
Claims23
A cover for a thermoplastic battery jar having relatively thin side walls which have a tendency to bow inwardly, said cover being comprised of a thermoplastic plate member having a predetermined thickness, top and bottom surfaces and four edges, a plurality of means defining openings extending through said plate member, and guide means, positioned at predetermined locations solely around the periphery of said plate member and extending downwardly away from said bottom surface, for interacting with the interior of said thin side walls of said battery jar and for aligning the cover therewith, said guide means being spaced inwardly a predetermined distance from said edges, said guide means having a length that varies from a first predetermined length at the corners of said cover to a second shorter predetermined length adjacent the central portion of each edge.
A cover as in claim 9 wherein said discontinuous skirt portions are offset inwardly from the remainder of said guide means in contact with the battery jar so that a passage is provided between said discontinuous skirt portions and the battery jar.
A battery jar cover comprised of a plate member having top, bottom and outer peripheral side surfaces that cooperate to define four sides and four corners and a plurality of openings extending therethrough, said cover further including a guide structure extending downwardly away from said bottom surface and solely about the periphery of said cover at predetermined locations, said guide structure being spaced inwardly from the sides of said cover and shaped so as to extend away from the bottom surface a shorter distance adjacent the central portion of a side than adjacent the corners defining that side.
A cover for a thermoplastic battery jar having relatively thin side walls comprised of a thermoplastic member having a predetermined thickness, top and bottom surfaces and four edges, a plurality of means defining openings extending through said plate member, and guide means positioned at least at predetermined portions about said plate member and depending away from said bottom surface for engaging at least complementary predetermined portions of the interior surface of the battery jar side walls and for aligning the cover therewith, said guide means for engaging the interior surfaces of said thin side walls being spaced inwardly a predetermined distance from said edges solely about said predetermined portions of the periphery of said cover and having a length that varies from a first predetermined length at predetermined corners of said cover to a second, shorter predetermined length at the central portion between said predetermined corners.
A covered battery jar comprising a battery jar including a base and four relatively thin, upstanding side walls having a tendency to bow inwardly prior to assembly of the cover thereon,
- cover means defining top and bottom surfaces for covering said battery jar, and including means defining at least one opening extending through said top and bottom surfaces;
- and
- guide means depending from said bottom surface at predetermined locations solely around the periphery thereof for engaging and straightening the inwardly bowed thin side walls, said guide means depending below said bottom surface a greater depth at predetermined corners thereof and gradually decreasing in said depending depth along the sides of said cover between said predetermined corners so that said guide means will first engage said battery jar at said predetermined corners thereof, and thereafter relative movement between said cover means and said battery jar will responsively cause that portion of said guide means having the next successively decreasing depending depth to engage an associated portion of the inwardly bowed side walls thereby successively decreasing the inward bow thereof.
