Mounting bracket for overhead window

Claim 2

A window mounting bracket, comprising: a. a pair of guide tracks adapted for mounting in confronting relation on a window frame and a window fitted therein respectively; b. a friction slide movable along each guide track; c. a pair of brace bars pivotally connected together intermediate their ends to form four extended ends, two of the ends being pivotally connected to the friction slides, and the remaining two ends being pivotally connected directly to respective guide tracks.

Claim 3

A window mounting bracket, as defined in claim 1, wherein: a. both of the friction slides are joined to one of the brace bars at respectively opposite ends thereof.

Claim 4

A window mounting bracket, as defined in claim 1, wherein: a. the friction slides are joined one to each of the brace bars.

Claim 5

A window mounting bracket assembly intended for use in pairs to support a window in its frame for movement about a horizontal axis near the top of the window between a closed position and an outwardly extended position, each bracket assembly comprising: a. a pair of similar guide tracks; b. a pair of similar friction slides one being received in each of the guide tracks and having adjustment means to vary the frictional force exerted by the slides; c. a pair of brace bars pivotally connected intermediate their ends; d. pivotal connections between selected ends of the brace bars and selected ends of the respective guide tracks; e. pivotal connections between the remaining ends of the brace bars and the respective friction slides; f. the pivotal connections being so located as to permit movement of the guide tracks between a confronting relation with the brace bars disposed between the guide tracks and an extended position wherein the guide tracks are disposed in angular relation.

Claim 6

A window mounting bracket assembly intended for use in pairs to support a window in its frame for movement about a horizontal axis near the top of the window between a closed position and an outwardly extended position, each bracket assembly comprising: a. a pair of similar guide tracks; b. a pair of similar friction slides one being received in each of the guide tracks and having adjustment means to vary the frictional force exerted by the slides; c. a pair of brace bars pivotally connected intermediate their ends; d. pivotal connections between selected ends of the brace bars and selected ends of the respective guide tracks; e. pivotal connections between the remaining ends of the brace bars and the respective friction slides; f. the pivotal connections being so located as to permit movement of the guide tracks between a confronting relation with the brace bars disposed between the guide tracks and an extended position wherein the guide tracks are disposed in angular relation.

Claim 7

A window mounting bracket assembly, as defined in claim 4, wherein: a. the pivotal connections between the friction slides and the brace bar ends being so located as to expose the friction slides for access to the adjustment means when the guide tracks are angularly disposed.

Claim 8

A window mounting bracket assembly, as defined in claim 4, wherein: a. both of the friction slides are joined to one of the brace bars at respectively opposite ends thereof.

Claim 9

A window mounting bracket assembly, as defined in claim 4, wherein: a. the friction slides are joined one to each of the brace bars.

Claim 10

A window mountIng bracket assembly, as defined in claim 4, wherein: a. the connections between the guide tracks, friction slides and brace bars being so located that, when a pair of bracket assemblies are joined to a window and its frame, movement of the window toward the open position causes a downward movement of its upper side away from the upper side of the frame, and movement of the window toward the closed position causes upward movement of its upper side toward the upper side of the frame.
