Independent Claim
221 words
In a window operating assembly for raising and lowering a window pane mounted in a wall structure; said assembly including mounting means; a guide rail secured to the wall structure by said mounting means; said guide rail assuming, in a secured, operative state, an orientation substantially parallel to the direction of motion of the window pane during a raising and lowering thereof; a sled mounted on the guide rail for back-and-forth travel thereon; connecting means for securing the sled to the window pane; and a drive cable attached to the sled for moving the sled on the guide rail; the improvement wherein said mounting means comprises (a) a plug-and-socket joint held in said wall structure and supporting a lower end of said guide rail; said plug-and-socket joint including first means for allowing said guide rail, in said secured, operative state thereof, to perform a pivotal motion in a direction substantially perpendicular to the plane of the window pane about a pivot point defined by said plug-and-socket joint; and (b) a support engaging said guide rail at a location thereof spaced from said lower end; said support including second means allowing said guide rail, in said secured, operative state thereof, to perform a freely sliding motion relative to said support in a direction substantially perpendicular to the plane of the window pane.
Claim 2
Dependent Claim

In a window operating assembly for raising and lowering a window pane mounted in a wall structure; said assembly including mounting means; a guide rail secured to the wall structure by said mounting means; said guide rail assuming, in a secured, operative state, an orientation substantially parallel to the direction of motion of the window pane during a raising and lowering thereof; a sled mounted on the guide rail for back-and-forth travel thereon; connecting means for securing the sled to the window pane; and a drive cable attached to the sled for moving the sled on the guide rail; the improvement wherein said mounting means comprises (a) a plug-and-socket joint held in said wall structure and supporting a lower end of said guide rail; said plug-and-socket joint including first means for allowing said guide rail, in said secured, operative state thereof, to perform a pivotal motion in a direction substantially perpendicular to the plane of the window pane about a pivot point defined by said plug-and-socket joint; and (b) a support engaging said guide rail at a location thereof spaced from said lower end; said support including second means allowing said guide rail, in said secured, operative state thereof, to perform a freely sliding motion relative to said support in a direction substantially perpendicular to the plane of the window pane.
Claim 3
Dependent Claim
72 words
A window operating assembly as defined in claim 1, wherein said second means comprises a guide web immobilized in said door in the secured, operative state of said guide rail; said guide web having a guide portion oriented substantially perpendicularly to the plane of the window pane and a slide member affixed to said guide rail; said guide portion of said guide web slidably supported in an opening in said slide member.
Claim 4
Dependent Claim
29 words
A window operating assembly as defined in claim 2, further comprising a securing bolt attaching said support to said door; said guide web having an eyelet surrounding said bolt.
