Abstract

A window sash installed into a window frame, wherein the window sash assumes an operable position where the vertical sides of the window sash are aligned with the side jambs of the window frame. A gap space exists between each of the vertical sides of the window sash and the side jambs of the window frame. This gap space is utilized by a counterbalance system. Spacer assemblies are attached to the window sash. Each spacer assembly has a base that mounts to the window sash and a slide that selectively extends from the base. The slides are extended across the gap spaces between the sash and the side jambs. The slides are brought into close proximity with the side jambs. The presence of the slides prevents the window sash from being able to cock out of the intended operational orientation of the window sash.

Claims (18)

1. A window construction, comprising:

a window frame having side jambs;

at least one window sash set within said side jambs of said frame, said window sash having at least one pane of glass supported between a top sash element, a bottom sash element and two side sash elements, wherein a gap space exists between each of said side sash elements and a respective one of said side jambs;

a base mounted to said top sash element, said base having an upwardly oriented catch that is supported by a flexible finger; and

a slide that engages said base and is selectively moveable along said base, said slide having downwardly oriented teeth, wherein some of said downwardly oriented teeth are engaged by said upwardly oriented catch on said base to prevent said movement of said slide along said base, said slide further including

a press plate formed into said slide, said press plate that engages said catch when manually depressed causing said flexible finger to deflect and said upwardly oriented catch to disengage from said downwardly oriented teeth and enable said slide to move along said base and selectively span a respective one of said gap spaces to prevent said window sash from cocking within said window frame; and wherein said base and said slide combine to form a spacer assembly.

2. The window construction according to claim 1 , wherein said base engages a corner of said window sash.

3. The window construction according to claim 2 , wherein said base has a bottom surface that rests upon said top sash element and a stop.

4. The window construction according to claim 1 , wherein said spacer assembly has a maximum height no greater than ¼ inch.

5. A window sash, comprising;

a sash framework containing a top sash element, a bottom sash element and at least two side sash elements;

at least one pane of glass supported by said sash framework; and

a spacer mounted to said top sash element, said spacer having a base and a slide that engages said base, said base having an upwardly oriented catch that is supported by a flexible finger, said slide being selectively moveable along said base, wherein said slide has downwardly oriented teeth, wherein some of said teeth are engaged by said upwardly oriented catch on said base to prevent said movement of said slide along said base;

said slide further including a press plate formed into said slide, said press plate engages said catch when manually depressed causing said flexible finger to deflect and said upwardly oriented catch to disengage from said downwardly oriented teeth and enable said slide to move along said base, wherein said slide is selectively extendable from said base a distance beyond said top sash element.

6. The window sash according to claim 5 , wherein said downwardly oriented teeth are spaced apart a predetermined increment.

7. The window sash according to claim 5 , wherein said sash framework has a corner and said base engages said corner.

8. The window sash according to claim 7 , wherein said base has a bottom surface that rests upon said top sash element and a stop that engages one of said side sash elements.

9. The window sash according to claim 5 , wherein said spacer has a maximum height no greater than ¼ inch.
