Abstract
Abstract A stop device for sliding doors or windows is described, wherein the device has a block member secured to the lower end of the sliding door so that the block member forms an appendage to the door and lying substantially within the plane of the door. The block member is formed symmetrical about a horizontal plane so that it can be used with either right or left-hand sliding doors, and has a vertical bore wherein a bolt or pin is disposed. Communicating with the bore is a horizontally disposed hole lying substantially on the horizontal plane. Within the hole is an inwardly biased steel ball. The bolt has two axially spaced circumferential grooves that are singularly engaged by the steel ball to provide predetermined stops for the bolt. The bolt can be inserted within the bore from either end.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
223 words
A stop device for a sliding door comprising: a block having a cylindrical bore of constant diameter therethrough; first means for attaching said block to a corner of said door so that said bore is disposed vertically; a pin slidably disposed within said bore; second means for engaging said pin at predetermined axial positions within said bore; said second means includes said block having a hole disposed normal to said bore and communicating with said bore; a ball disposed within said hole; third means for spring biasing said ball against said pin; said pin having indentations to receive said ball so at a larger force is required to axially slide said pin when the ball engages one of said indentations, that when not engaging an indentation; said first means includes a flange formed on said block and said block is bolted to said door by the use of said flange; said block being rectangular, having a height and width substantially equal to each other and a thickness less than the height and width; said flange extending from one face thereof to form on said block a recessed corner to receive said door; said block having grooves formed on said upper edge and upper and lower surfaces, said bore being disposed on one side of said groove on the same side of said flange.
Claim 2
Dependent Claim
223 words
A stop device for a sliding door comprising: a block having a cylindrical bore of constant diameter therethrough; first means for attaching said block to a corner of said door so that said bore is disposed vertically; a pin slidably disposed within said bore; second means for engaging said pin at predetermined axial positions within said bore; said second means includes said block having a hole disposed normal to said bore and communicating with said bore; a ball disposed within said hole; third means for spring biasing said ball against said pin; said pin having indentations to receive said ball so at a larger force is required to axially slide said pin when the ball engages one of said indentations, that when not engaging an indentation; said first means includes a flange formed on said block and said block is bolted to said door by the use of said flange; said block being rectangular, having a height and width substantially equal to each other and a thickness less than the height and width; said flange extending from one face thereof to form on said block a recessed corner to receive said door; said block having grooves formed on said upper edge and upper and lower surfaces, said bore being disposed on one side of said groove on the same side of said flange.
