Corner bracket and roller assembly for sliding doors

Claim 2

A corner bracket and roller assembly for sliding doors having hollow, mating rails with flat faces and spaced end walls rollformed to make each of said rails comprising: a press-formed L-shaped corner bracket having a bottom portion and spaced flanges integral with said bottom portion and upstanding therefrom, said flanges being in compression fit with said flat faces and said end walls of said mating rails, said corner bracket further having a bolt receiving sleeve press-formed into said bottom portion of said bracket. a roller assembly pivotally mounted within one of said rails and to said bottom portion of said bracket assembly and extending beyond a free end of said bracket, spring means engaging said roller assembly and one of said flanges of said bracket for urging said roller assembly to extend partially outside of said one of said rails, a detent integrally connected to said roller assembly and extending outwardly therefrom, detent receiving means in the other of said Flanges of said bracket to releasably engage said detent, and a bolt threadingly engaging said sleeve for movement longitudinally of said bottom of said bracket, one end of said bolt being adapted to contact said roller assembly, whereby longitudinal movement of said bolt moves said detent of said pivotally mounted roller assembly out of engagement with said groove.

Claim 3

A corner bracket and roller assembly for sliding doors having hollow, mating rails with flat faces and spaced end walls roll-formed to make each of said rails comprising: a press-formed L-shaped corner bracket having a bottom portion and spaced flanges integral with said bottom portion and upstanding therefrom, said flanges being in compression fit with said flat faces and said end walls of said mating rails, said corner bracket further having a bolt receiving sleeve press-formed into said bottom portion of said bracket. a roller assembly pivotally mounted within one of said rails and to said bottom portion of said bracket assembly and extending beyond a free end of said bracket, spring means engaging said roller assembly and one of said flanges of said bracket for urging said roller assembly to extend partially outside of said one of said rails, a detent integrally connected to said roller assembly and extending outwardly therefrom, detent receiving means in the other of said Flanges of said bracket to releasably engage said detent, and a bolt threadingly engaging said sleeve for movement longitudinally of said bottom of said bracket, one end of said bolt being adapted to contact said roller assembly, whereby longitudinal movement of said bolt moves said detent of said pivotally mounted roller assembly out of engagement with said groove.

Claim 4

A corner bracket and roller assembly for sliding doors having hollow, mating rails with flat faces and spaced end walls roll-formed to make each of said rails comprising: a press-formed L-shaped corner bracket having a bottom portion and spaced flanges integral with said bottom portion and upstanding therefrom, said flanges being in compression fit with said flat faces and said end walls of said mating rails, said corner bracket further having a bolt receiving sleeve press-formed into said bottom portion of said bracket. a roller assembly pivotally mounted within one of said rails and to said bottom portion of said bracket assembly and extending beyond a free end of said bracket, spring means engaging said roller assembly and one of said flanges of said bracket for urging said roller assembly to extend partially outside of said one of said rails, a detent integrally connected to said roller assembly and extending outwardly therefrom, detent receiving means in the other of said Flanges of said bracket to releasably engage said detent, and a bolt threadingly engaging said sleeve for movement longitudinally of said bottom of said bracket, one end of said bolt being adapted to contact said roller assembly, whereby longitudinal movement of said bolt moves said detent of said pivotally mounted roller assembly out of engagement with said groove.

Claim 5

A corner bracket and roller assembly as recited in claim 1, in which said roller assembly comprises a pair of spaced legs integrally connected to a narrow base wall along edges of said base wall, and said detent is an integral extension of the top of said base wall extending upwardly and forwardly toward the free ends of said legs.

Claim 6

A corner bracket and roller assembly as recited in claim 1 in which said bolt receiving sleeve has a central portion pressed upwardly between two parallel cuts in said bottom portion and is adjacently located with respect to two reversely downwardly formed adjoining portions of said bottom portion of said bracket.

Claim 7

A corner bracket and roller assembly as recited in claim 1 in which said bottom of said bracket has a strengthening dimple therein.

Claim 8

A corner bracket and roller assembly as recited in claim 1 in which said roller assembly comprises a pair of spaced legs integrally connected to a narrow base wall along the edges of said base wall, and a wheel mounted on a removeable pin engaging said spaced legs at points remote from said base wall.

Claim 9

A corner bracket and roller assembly comprising: a press-formed L-shaped corner bracket having a bottom portion and spaced flanges integral with said bottom portion and upstanding therefrom, said corner bracket further having a bolt receiving sleeve press-formed into said bottom portion of said bracket, a roller assembly pivotally mounted to said bottom portion of said bracket assembly and extending beyond a free end of said bracket, a detent integrally connected to said roller assembly and extending outwardly therefrom toward one of said flanges, a detent receiving means formed in said one of said flanges for releasably engaging said detent, and a bolt threadingly engaging said sleeve for movement toward and away from said roller assembly, one end of said bolt being adapted to contact said roller assembly, whereby longitudinal movement of said bolt releases said detent of said pivotally mounted roller from engagement with said detent receiving means.

Claim 10

A corner bracket and roller assembly comprising: a press-formed L-shaped corner bracket having a bottom portion and spaced flanges integral with said bottom portion and upstanding therefrom, said corner bracket further having a bolt receiving sleeve press-formed into said bottom portion of said bracket, a roller assembly pivotally mounted to said bottom portion of said bracket assembly and extending beyond a free end of said bracket, a detent integrally connected to said roller assembly and extending outwardly therefrom toward one of said flanges, a detent receiving means formed in said one of said flanges for releasably engaging said detent, and a bolt threadingly engaging said sleeve for movement toward and away from said roller assembly, one end of said bolt being adapted to contact said roller assembly, whereby longitudinal movement of said bolt releases said detent of said pivotally mounted roller from engagement with said detent receiving means.

Claim 11

A corner bracket and roller assembly as recited in claim 6, in which said roller assembly comprises a pair of spaced legs integrally connected to a narrow base wall along edges of said base wall, and said detent is an integral extension of the top of said base wall extending upwardly and forwardly toward the free ends of said legs.

Claim 12

A corner bracket and roller assembly as recited in claim 6 in which said bolt receiving sleeve has a central portion pressed upwardly between two parallel cuts in said bottom portion and is adjacently located with respect to two reversely downwardly formed adjoining portions of said bottom portion of said bracket.

Claim 13

A corner bracket and roller assembly as recited in claim 6 in which said bottom of said bracket has a strengthening dimple therein.
