Rodenbaugh, 416 Goodland Circle 38111, both of Memphis, Tenn Filed Oct. 20, 1967, Ser. No. 676,746 Claims. (Cl. 49-407) ABSTRACT OF THE DISCLOSURE For use in a double sash window installation including a somewhat typical window frame having a longitudinally grooved horizontal head jamb member and a somewhat typical vertical Weatherstrip member having parting bead wall means defining a longitudinally extending grooved back. The inventive structure includes a small clip-like key adapted to be adjustably fitted over the upper edge portion of the Weatherstrip parting bead wall for interposingly interlocking the Weatherstrip and the head jamb in a window installation. The interlocking key being adapted to be manipulated from an inactive to an active configuration as the window installation is being fabricated. The interlocking key being adapted to be manipulated from a lowered inactive disposition to a raised active disposition wherein a head portion of the key is permanently received in the horizontal groove in the window frame head jamb.

Background of the invention Field of the inventi0n.-It relates to the typical residential double-hung double sash window installation; the invention particularly relates to fastening means for fastening Weatherstrip members in window framing.

Description of the prior art.-In prior art residential building construction, the typical practice is to nail or staple the Weatherstrip to the side jamb. In the typical double-hung window installation, the upper and lower sashes and the left and right Weatherstrip-balance assemblies are installed together and substantially as a unit. At this stage in the window installation fabrication it is desirable to have a ready way for supporting or fastening the sash and Weatherstrip unit in the window frame. Heretofore, it has been somewhat awkward for a workman to properly align, hold and nail a sash and weatherstrip unit. Often it is desirable to slightly shift the unit or the Weatherstrip part of the unit after it has been initially positioned in the window frame. A particular problem in window fabrication has been the difficulty in properly aligning a Weatherstrip with the side jamb parting bead groove and the head jamb parting bead groove in the window frame. In the prior art practice of nailing a Weatherstrip to the side jamb, there was considerable likelihood that the Weatherstrip member would be improperly positioned. When this was so, it was difficult to remove the nail fasteners and reposition the Weatherstrip.

Summary of the invention The present invention provides a ready way for quickly and accurately positioning a sash-Weatherstrip assemblage in a window frame. A left and a right interlocking key is hooked respectively over the parting bead wall of the left and right Weatherstrip of the sash-Weatherstrip assembly, and as the window installation is being made, the pair of interlocking keys (left and right key members) are moved upwardly into the head jamb parting 3,418,754 Patented Dec. 31, 1968 ICC bead groove. This correctly positions and secures the sash-Weatherstrip assembly in the window frame.

Each interlocking key is adapted to be frictionally secured on a respective Weatherstrip in an inactive disposition; preferably, an interlocking key is frictionally secured on each Weatherstrip member as each member is packaged for shipment. A purchaser or user of a weatherstrip-sash assembly, as the assembly is being installed in a window frame, has only to simultaneously manipulate the pair of interlocking keys from inactive dispositions (as shipped or packaged) to an active and locked disposition. No nails, staples or other fasteners are required in installing a sash-Weatherstrip assembly in a window frame; no tools are required to install the sash-weatherstrip unit and it can be positioned in the window frame entirely by hand. Each interlocking key is frictionally secured on a respective Weatherstrip member, thus preventing the likelihood of misplacing an interlocking key; no nails or other loose fasteners are required in the installation of a sash-Weatherstrip assembly and all necessary parts for such an assembly may be shipped as a package.

Left and right interlocking keys, after they are installed in a window installation, also function as stop member means for stopping the upward movement of the lower sash of the window installation. When the lower sash is moved to a fully open position, the upper corner portions of the lower sash engage the left and right key members and prevent the sash from abuttingly engaging the underside of the head jamb. Such interlocking key stop means prevents damaging the lower sash and head jamb as the window is moved upwardly to a fully open disposition.

FIG. 5 is a horizontal plane sectional view of the key member as viewed upwardly and along line VV of FIG. 4.

Description of the preferred embodiment In the drawing only one interlocking key 'r'nember (a righthand key member) is illustrated and only the upper righthand portion of a window installation is illustrated: Upper and lower window sashes 11, 13 (fragmentarily shown in broken lines) are slidably secured in a window frame in a typical manner. A right side jamb 15 and Weatherstrip member 17, and a head jamb 19 guidingly constrain upper and lower sashes 11, 13 in the window frame in a typical manner. Weatherstrip member 17 typically extends from the window sill (not shown) to head jamb 19 and with the back of the Weatherstrip member correspondingly confrontingly engaging inward surface 21 of side jamb 15. Weatherstrip member 17 includes structure defining inside and outside

guideways

23, 25 for guidingly constraining respectively inside lower sash 13 and outside upper sash 11. Weatherstrip member 17 typically includes longitudinally extending vertical inside and

outside terminal flanges

27, 29 and inside and outside tubular sash

balance spring housings

31, 33.

Weatherstrip member 17 includes longitudinally extending vertically arranged parting bead wall structure including inward and outwardly disposed parting

bead wall portions

35, 37 respectively and a medial wall portion 39 integrally interconnecting

wall portions

35, 37. U-sectioned parting

bead wall structure

35, 37, 39 extends the full length of Weatherstrip member 17 and defines a longitudinally extending enclosed area 41 extending vertically from the window frame sill member (not shown) to underside surface 43 of head jamb 19. Member 17 is spaced a slight distance below head jamb 19 and the space between head jamb undersurface 43 and Weatherstrip upper edge 45 defines a horizontally extending gap 47.

Head jamb 19 typically includes a longitudinally extending horizontal head jamb parting bead grooveway 49 defined by inward and outward

groove wall surfaces

51, 53 and a groove bottom surface 55. A window frame facing member 57 is typically secured on outward edge surface 59 of side jamb 15. Outside flange portion 29 of Weatherstrip member 17 is adapted to abuttingly engage inward surface 63 of facing member flange portion 61. The size and configuration of the various window components is such that with Weatherstrip outside flange 29 engaging facing flange 61 Weatherstrip parting

bead wall structure

35, 37, 39 is vertically aligned with grooveway 49 in head jamb 19.

The interlocking key of the invention is indicated by numeral 65 and will be described as illustrated in the drawings, and as in its normally arranged disposition: Interlocking key 65 is of generally inverted U-configuration and includes parallel vertically extending trunk and

spur portions

67, 69 respectively. A head portion 71 including a head hook portion 73 and a spur hook portion 75 interconnect trunk portion 67 and spur portion 69. Interlocking key 65 is preferably formed integrally of substantially hard somewhat resilient plastic material; key 65 is preferably cross-cut formed from an extruded bar of plastic material, and such a bar having a cross-sectional configuration as seen in FIGS. 1 and 2.

Trunk portion 67 and head portion 69 are integrally joined and are each generally rectangular in cross-sectional configuration. Head hook portion 73 and spur hook portion 75 are generally thin and flat in transverse cross section and are arranged generally in an L-configuration (as viewed laterally in FIGS. 1 and 2). Head hook portion 73 is integrally secured at its upper portion 77 to the upper portion of head portion 71 of trunk 67. Head hook portion 73 curves outwardly and downwardly from head portion 71 and extends generally vertically downwardly to an integral intersection with horizontal spur hook portion 75. A transversely extending detent rib portion 79 is integrally secured to and protrudes slightly downwardly from the underside of spur hook portion 75 adjacent its intersection with head hook portion 73. The open space between head portion 71 and head hook portion 73 defines a vertically extending downwardly opening throat 81. Spur hook portion 75 is integrally secured to and projects horizontally from upper portion 83 of spur portion 69. Spur portion upper portion 83 in conjunction with spur hook portion 75 and detent rib portion 79 define a transversely extending downwardly oriented recess 85.

Key 65 is adapted to be vertically manipulated from a lowered inactive disposition (FIG. 2) to a raised active disposition (FIG. 1). When in an inactive disposition, key 65 is pendantly supported from Weatherstrip member 17 with head hook portion 73 hooked over the upper edge portion of Weatherstrip member parting bead wall 35; the upper portion of parting bead wall 35 is frictionally received in throat 81 of the interlocking key. When in a raised active disposition (FIG. 1), interlocking key 65 is dependingly supported from Weatherstrip member 17 with spur hook portion 75 hooked over the upper edge portion of Weatherstrip member parting bead wall 35; when in a raised disposition head portion 71 of key 65 is snugly arranged in head jamb grooveway 49 and interlocks the head jamb and Weatherstrip member. With key 65 in a raised and locked disposition, detent rib 79 is arranged substantially within enclosed area 41 and contiguous the upper edge portion of parting bead inward wall 35; detent rib 79 prevents inadvertent relative displacement of Weatherstrip member 17 and key 65 as the window installation is being fabricated.

In installing a window assembly including upper and lower sashes and right and left Weatherstrip members the assembly is substantially installed in a window frame as a unit assembly. In installing the sash-Weatherstrip assembly the window sashes are arranged in lowered positions between the right and left Weatherstrip members and the assembly is restingly positioned on the sill section of the window frame. The upper portions of the Weatherstrip members and sash assembly is then canted inwardly into the upper section of the window frame. During this stage of the window installation the left and right interlocking keys 65 are arranged in lowered inactive dispositions as illustrated in FIG. 2. The right and left Weatherstrip members are pressed away from the workman and forwardly until the outside flange portions 29 of the left and right Weatherstrip members 17 abuttingly engage flange portions 61 of frame facing members 57. The workman continues the outward movement of the Weatherstrip members and in so doing moves head portions 71 of interlocking keys 65 past head jamb grooveway 49; by thumb pressing upwardly on spur portions 69 of the left and right interlocking keys 65 as the interlocking keys 65 move past grooveway 49, the keys are vertically shifted into the head jamb grooveway, thus locking the sash-Weatherstrip unit in the window frame.

As is readily apparent, the size and shape of interlocking key 65 and the size and shape of the various coacting elements of the window installation are relative: The transverse configuration of interlocking key trunk and

head portions

67, 71 are relative to the transverse configuration of Weatherstrip member parting

bead wall structure

35, 37, 39. The transverse horizontal configuration of interlocking key head portion 71 and grooveway sidewall surfaces 51, 53 are also relative. hr the interlocking key structure per se, the vertical thickness of head hook portion upper portion 77 should be substantially commensurate with the vertical thickness of spur hook portion 75. Moreover, the vertical thicknesses respectively of

portions

75, 77 should each be the same or slightly less than the vertical dimension of horizontal gap 47 of the gap width defined by upper edge 45 of weatherstrip member 17 and undersurface 43 of head jamb 19.

The horizontal width of interlocking key throat 81 should be less than the wall thickness of Weatherstrip parting bead wall portion 35; the vertically extending head hook portion 73 of key 65 is preferably canted slightly inwardly toward trunk portion 67, when parting bead wall portion 35 is not received in throat 81 (see FIGS. 1 and 4). By virtue of the resilient characteristics of the plastic material of spur hook portion 75, spur hook portion 73 is resiliently urged inwardly toward trunk portion 67 and is adapted to frictionally engage parting bead wall portion 35.

The lower end surface of spur portion 69 of interlocking key 65 is adapted to abuttingly engage the upper surface of lower inside sash 13 to prevent damage to sash l3 and head jamb 19 (see FIG. 1). Thus, spur portion 69 provides stop means for stopping the upward movement of lower sash 13 when it is moved to a fully open disposition.

Now while I have shown and described a preferred embodiment of the present invention, it will be understood that variousmodifications and rearrangements of structure may be made without departing from the scope of the invention as defined in the appended claims.
