Manias ABSTRACT A closure spacer member extruded from a resilient' substance such as rubber or plastic to have a spacer element and a tear-away sealing lip. The spacer member is useful in fixed frame assemblies of the type having exterior and interior perimeter retainer beads, and closures, such as windows, decorative panels and the like, installed between the perimeter retainer beads. When installed, the sealing lip of the spacer member fills a sealant receiving perimeter recess of the fixed frame assembly from the time the closure is initially installed until the sealant is to be applied. At a future time, the tear-away sealing lip is detached and a sealant is installed in the clean, sealant receiving perimeter recess. A method of erecting a fixed frame assembly is described.
CLOSURE SPACER MEMBER AND METHOD OF ERECTING A FIXED FRAME ASSEMBLY BACKGROUND OF THE INVENTION 1. Field of the Invention:
This invention relates to fixed frame assemblies, and more particularly to an improved glazing spacer member having a tear-away lip for temporarily sealing a sealant receiving perimeter recess of the fixed frame assembly.
2. Description of the Prior Art:
In modern curtain wall constructions, vertical and horizontal metallic members are assembled as a grid to provide plural fixed frame assemblies each defining an opening. The openings receive closures, such as glazing panes, decorative panels and the like. Other closure receiving fixed frame assemblies are known for use as store fronts. See U. S. Pat. Nos. 3,016,993 (H. L. OWEN, Jan. 16, 1962), 3,038,568 (G. W. MORGAN, June 12, 1962), 3,196,998 (H. L. OWEN, July 27, 1965).
In fixed frame assemblies, the closure is positioned between exterior and interior perimeter retainer beads and normally rests upon two or more spaced stop members mounted at the bottom of the frame assembly. A resilient sealing strip is positioned between the closure and the interior perimeter retainer bead. A spacer, in the form of a continuous resilient strip or plural flexible elements, is positioned between the closure and the exterior perimeter retainer bead'such that a sealant receiving perimeter recess is provided. A weather sealant, such as thiokol rubber, is introduced into a sealant receiving perimeter recess.
In the assembly of modern buildings, the closures frequently are installed from the inside of the building framework in order to enclose the space as rapidly aspossible. The exterior weather sealant may not be installed for quite some time after the closures have been secured in position. At the later date, perhaps months later in some cases, the glazier working from exterior scaffolding must clean out the sealant receiving perimeter recess. Thereafter, the recess is filled with a sealant, such as thiokol rubber. The cleaning operation is extremely difficult and time consuming.
SUMMARY OF THE INVENTION detachably connected to and extending along the length of the spacer element. The sealing lip and the spacer element may be extruded as an integral unit.-
The spacer member preferably is formed from a resilient substance, such as rubber or plastic, whereby the sealing lip may be detached by tearing from the spacer element. The spacer element preferably is provided with a lug which serves to resist inadvertent removal of the spacer element during detachment of the sealing lip.
The present invention also provides improvements in the method of erecting a fixed frame assembly wherein a closure is positioned between exterior and interior perimeter retainer beads each of which presents an inner perimeter edge. In accordance with the present edge. The sealing lip serves as a temporary seal until such time as caulking material is to be installed". Thereafter, the sealing lip is detached from the spacer element to expose a perimeter recess defined by the spacer element and the confronting faces of the closure and the perimeter retainer bead. The perimeter recess is then filled with a permanent weather sealant.
The term closure as used in this specification and the appendedclaims is intended to include light transmitting closures, such as transparent and translucent windows or plastic sheets; and decorative infill closures, such as insulated and uninsulated'panels, opaque glass sheets,- opaque plastic sheets, natural and syntheitc stone slabs, andthe like.

FIG. 15 is a fragmentary cross-sectional view illustrating detachment of a sealing lip of the spacer member of FIG. 14.
DESCRIPTION OF THE PREFERRED EMBODIMENT(S) FIGS. 1, 2 and 3 illustrate a closure spacer member comprisinga spacer element 11 and a sealing lip 12 which is connected to the spacer element 11 along a relatively narrow common region 13. In the preferred arrangement, the spacer member 10 is extruded from a resilient substance, such as rubber or plastic, whereby the sealing lip 12 may be detached by tearing along the common region 13, as illustrated in FIG. 1. As the sealing lip 12 is'detached, a ragged edge or strip 14 (FIG. 1) is presentedby thespacer element 11.
The spacer member 10 may be provided with an-attaching lug 19 which extends along the length of the spacer element 11 and which is spaced-apart from the sealing lip 12. The attaching lug 19 serves to connect the spacer element 11 to a perimeter retainer bead thereby to resist removal of the spacer element 11 during detachment of the sealing lip 12, as will be described.
FIG. 4 illustrates a typical fixed frame assembly 20 wherein a closure such as a glazing pane 21 is retained within a perimeter frame 22. As best shown in FIG. 5, the perimeter frame 22 includes exterior and interior perimeter retainer beads 23, 24, respectively. The perimeter retainer beads 23, 24 present inner perimeter faces25, 26 respectively.
interposed between the interior perimeter retainer bead 24 and the glazing pane 21.
In accordance with the present invention, the spacer member 10 is placed between confronting faces 29, 30 presented by the glazing pane 21 and one of ,the perimeter retainer beads, for example, the exterior perimeter retainer bead 23. The-spacer member 10 may be attached to the exterior retainer bead 23 by introducing the attaching lug 19 into a groove 31 provided in the exterior perimeter retainer bead 23. The spacer member 10 extends along'substantially the entire length of the inner perimeter face with the sealing lip 12 exposed to view.
It willbe observed in FIG. 6 that as the sealing lip 12 is detached from the spacer element 11, a sealant receiving perimeter recess 32 is exposed. The perimeter recess 32 is defined by the spacer element 11 and the confronting faces 29, of the glazing pane 21 and the exterior perimeter retainer bead 23. It will also be observed in FIG. 6 that the ragged edge or strip 14 created by detaching the sealing lip 11 is presented by the spacer element 11 at the perimeter recess 32.
Returning now to FIG. 5, it will be observed that the sealing lip 12 temporarily fills the sealant receiving perimeter .recess v32 until such time as a permanent weather sealant is to be installed. At a later date, perhaps months later in some cases, the glazier may detach the sealing lip 12 by hand (FIG. 6) from the spacer element 11. Alternatively, the glazier may employ a suitable tool, such as a pair of pliers 33 (FIG. 4) to detach the sealing lip 12. When the sealing lip 12 is completely removed, a completely clean sealant receiving perimeter recess 32 is presented. The glazier is able to quickly apply a weather sealant 34 (FIG. 7) to completely seal the perimeter recess 32. It will be appreciated that the present spacer member 10 avoids the necessity of ex- 4 pensive cleaning operations which would be required if,'as in the past, the sealant receiving perimeter recess 32 was left unprotected from the time the closure was initially installed until the weather sealant was to be applied.
It will be appreciated that the positions of the resilient sealing strip 28 and the present spacer member 10 (FIG. 5) may be reversed thereby positioning the present spacer member between the glazing pane 21 and the interior perimeter retainer bead 24. Alternatively, the resilient ceiling strip 28 may be replaced by one of the present spacer members 10.
It will also be appreciated that the present spacer 10 may also be employed in fixed frame'assemblies which incorporate decorative closures such as the insulated panel 18 (FIG. 8).
The configuration and use of alternative embodiments of the present closure spacer member are illustrated in FIGS. 9 through 15. Corresponding numerals will be employed to identify corresponding parts heretofore described.
FIG. 9 illustrates a spacer member 35 having a relativelylarge lug 36 extending laterally of the spacer ele-' ment 11. The lug 36 may extend continuously along the length of the spacer member 35. Alternatively, short lengths of the lug 36 may be provided at longitudinally spaced locations along the'length of the spacer element 11. When the spacer member'35 is installed (FIG. 10) the lug 36 engages the perimeter edge 37 of the closure 21. In this'embodiment, the lug 36 maintains the closure 21 spaced from the fixed frame assembly 20. No stop members 27 (FIG. 5') are needed in the FIG. 10
arrangement. It will also be observed in FIG. 10 that the lug 36 serves an additional. function. That is, by engaging the perimeter edge 37 of the closure 21, the lug 36 resists inadvertent removal of the's pacerelement 1 1 during detachment of the sealing lip 12.
FIG. -11 illustrates a spacer member 38 having a relatively narrow lug 39 extending laterally of the spacer element 11. The lug 39 may extend continuously along the length of the spacer element 11 or may be provided in short lengths which are spaced along the length of the spacer element 11. When the spacer member 38 is installed (FIG. 12) the lug 39 engages the perimeter edge 37 of the closure 21. Thus engaged,"the lug'39 resists inadvertent removal of the spacer element 11 during detachment of the sealing lip 12.
FIG. 13 illustrates a spacer member40having a relatively thin lifting strip 41 extending substantially the entire length of the sealing lip 12. The lifting strip 41 is formed integrally with the top of the sealing lip 12 and extends laterally thereof in the same direction as the attaching lug 19. The lifting strip 41 serves two important functions which will hereinafter be described. In
- this embodiment, .the sealing lip is connected to the spacer element along the relatively narrow commmon region 13 and along a second relatively narrow common region 42.
FIG. 14 illustrates the spacer member 40 installed be-,
tween the closure 21 and the exterior perimeter retainer bead 24. It will be observed that the lifting strip 41 overlies and protects that portion of the inner pe- It will be observed in FIG. that the sealing lip 12 may be detached from the spacer element 11 by grasping and pulling the lifting strip 41 anywhere along the length of the spacer member 40. Thus the second important function of the lifting strip 41 is that it provides a means by which the sealing lip 12 may be detached from the spacer element 11 without the aid of special or conventional tools.
