United States Patent 3,325,945 SIDE JAMB-WEATHERSTRiP INTERLGCKING KEY Thomas J. Beasley, Jr., and Richard P. Rodenbnugh, Memphis, Tenn., assignors to Southern Metal Products Corporation, Memphis, Tenn.

Filed Get. 22, 1965, fier. No. 501,853 Claims. (Cl. 49-434) ABSTRACT 0F THE DISCLOSURE For use in a double sash window installation including a longitudinally vertically grooved wooden side jamb and a Weatherstrip having a longitudinally vertically extending grooved backa small clip-like key adapted to be fitted in the corresponding confrontingly arranged grooves of the side jamb and Weatherstrip member and fixedly secured in the uuderportion of the head jamb of the window frame for securing the Weatherstrip member in the window frame.

This invention relates to a double sash window installation including a wood window frame and an opposingly arranged pair of Weatherstrip members. More specifically, the invention relates to a substantially small clip-like key member for securing a Weatherstrip member to a window frame.

The typical wooden window frame is rectangular and includes oppositely arranged vertically extending side jamb members and a horizontal head jamb member fixedly bridged across the upper ends of the side jamb members. Each side jamb member is provided with a longitudinally extending grooveway along the inward side. In certain window installations a long narrow wooden parting strip is fixed in the grooveway and serves as guide means between the upper and lower window sashes. In other window installations, a pair of sheet metal weatherstrip members or a pair of Weatherstrip and balance assemblies are used to operatively secure the window sashes. In prior art window installations using weatherstrip or Weatherstrip sash balance assemblies the grooves in the side jam members of the Window frame are not used and the Weatherstrip member or Weatherstrip jamb assemblies are fixedly secured to a respective jamb member by stapling, nailing or the like. The typical wood window frame therefore serves as a combination sort of frame which can optionally be used in the cheaper window installation employing a wood parting strip or in a more expensive installation employing Weatherstrip members or Weatherstrip and sash jamb assemblies.

The present invention concerns the window installation employing Weatherstrip members or Weatherstrip and sash balance assemblies. For the stake of clarity, in this specification the invention will be described as being in a window installation employing Weatherstrip members; it is apparent, however, that the invention is equally applicable in an installation including weatherstrip and sash balance assemblies.

The general object of the present invention is to provide a substantially simple and fast way for attaching a Weatherstrip member to a respective window frame side jamb without nailing, stapling or employing other such costly means.

A further object is to provide a substantially small clip-like key member of one-piece sheet-metal form which is economical to make and easy to install.

A further object is to provide an interlocking key member interengaging the respective grooveway portions of the Weatherstrip member and Window frame side jamb member and for preventing relative lateral displacement of the members.

ice

A further object is to provide a side jamb-Weatherstrip interlocking key member including barb-like cleat means securable in the window frame head jamb member for additionally securing the Weatherstrip member.

The means by which the foregoing and other objects of the present invention are accomplished and the manner of their accomplishment will be readily understood with reference to the accompanying drawings in which:

FIG. 1 is a view of a double sash window installation and such window structure including the interlocking key on the line V-V of FIG. 1.

FIG. 2 is a perspective view of the interlocking key member.

FIG. 3 is a perspective view of the interlocking key member as installed and interengaging the Weatherstrip and side jamb members (partly shown) and with the Window frame head jamb member removed.

FIG. 4 is a vertical plane sectional view taken as on the line IVIV of FIG. 1, but with the upper window sash slightly lowered.

FIG. 5 is a horizontal plane sectional view taken as on the line VV of FIG. 1.

FIG. 6 is a prior art horizontal plane sectional view taken as along a section corresponding to FIG. 5 and illustrating the attachment of the Weatherstrip member with nails. In the prior art view the window frame side jamb member is indicated by letter A, the upper sash member by letter B, the Weatherstrip member by letter C and the nails attaching the Weatherstrip member by letter D.

The window installation is indicated by numeral 11 in FIG. 1 and illustrates upper and

lower window sashes

13, 15 slidably secured respectively in opposingly arranged

weatherstrip members

17, 19. A substantially rectangular window frame 21 having right and left

side jamb members

23, 25 and a head jamb member 27, frames the window sashes and with Weatherstrip

members

17, 19 respectively arranged along

side jamb members

23, 25.

Since the right and left components of window installation 11 are substantially alike, the inventive structure will be described in conjunction with the right side components, it being apparent that the left side components of the window installation are similarly arranged.

FIGS. 3, 4 and 5 illustrate the interlocking key means of the present invention in conjunction with the window frame side jamb and head jamb members, 23, 27 respectively; Weatherstrip member 17; and upper sash member 13. The longitudinally extending grooved portions respectively of side jamb member 23 and weatherstrip member 17 are confrontingly matched and define a vertically extending enclosed area 29 terminated at the upper end by head jamb member 27. Thus, the longitudinal

grooved portions

31, 33 respectively of side jamb member 23 and Weatherstrip member 17 are confrontingly arranged and define the vertically extending enclosed area 29. An interlocking key member 35, comprising the principal element of the invention, forms the interlocking structure between side jamb member 23 and Weatherstrip member 17.

Interlocking key member 35 is preferably of one-piece sheet-metal form and includes basically a body part 37 and a pair of cleat parts 39, 39'. Body part 37 is elongated and substantially U-shaped cross-sectionally and includes an intermediate portion 41 and a pair of parallel arranged side portions 43, 43' (see FIG. 2). Cleat parts 39, 39' include respectively base portions 45, 45' and barb portions 47, 47'. It will be understood that barb portions 47,

47 may be omitted without departing from the spirit and scope of the present invention. Cleat parts 39, 39' are integrally secured respectively to the distal upper portion of respective side portions 43, 43' of body part 37 with the

respective base portions

45, 45 being substantially co-planar.

Barb portions

47, 47 project respectively upwardly and are integrally secured respectively to base portions 45, 45'; barb portions 47, 47' preferably are in the form of right angular projections struck from the

respective base portions

45, 45.

The body part of interlocking key 35 preferably is of such cross-sectional proportions as to snugly fit enclosed area 29. Key member 35 is arranged with the oppositely extending

cleat parts

39, 39 projecting perpendicularly outwardly respectively from parallel wall portions 49, 49' of Weatherstrip member groove portion 33. Horizontally extending base portions 45, 45' of cleat parts 39, 39' rest on or are contiguous with the upper edge surface 51 of Weatherstrip member groove portion 33 when the key member is being inserted, as will be better understood in the description of the installation to follow hereinafter, but is held upwardly away from the edge surface of the Weatherstrip by the

barb portions

47, 47 when the installation is completed as shown in FIG. 4. Interlocking key member 35 is arranged with the upper surfaces respectively of cleat parts 39, 39' in flat face-toface engagement with the under surface 53 of head jamb member 27 and with the respective barb portions 47, 47' secured in the under portion of the head jamb memher (see FIG. 4). The oppositely facing

flat surfaces

55, 55 of body part side portions 43, 43' respectively engage the parallel groove-wall surfaces of side jamb groove portion 31 and the parallel groove-wall surfaces of Weatherstrip groove portion 33, and prevent relative lateral displacement of the side jamb member and Weatherstrip member.

Interlocking key member 35 may be installed in window installation 11 in the following manner: both upper and

lower sashes

13, 15 are moved respectively to fully lowered positions; the upper portion of Weatherstrip member 17 is sprung outwardly away from window frame side jamb member 23; interlocking key member 35 is inserted in Weatherstrip groove portion 33 with the

respective cleat parts

39, 39 projecting respectively outwardly from the groove portion and resting on the upper edge 51; the Weatherstrip member is moved outwardly against the side jamb member and until the intermediate portion 41 of locking key member body part 37 engages the bottom surface of the side jamb member grooveway. It will be understood that there is a slight space between the upper edge of the Weatherstrip member 17 and head jamb member 27, which space is greater than the height of

barbs

47, 47 so thatthe above-mentioned outward movement is possible. The upper and

lower sashes

13, 15 are then separately raised, to forcefully strike the respective cleat parts 39, 39' which moves the key member upwardly and sets the

respective barb portions

47, 47 in head jamb member 27.

The interlocking key means of the present invention provides a substantially simple and fast way to attach a Weatherstrip member to a window frame without nailing, stapling or other such costly fastening means. The key member of the present invention is of one-piece construction and is economical to make and easy to install. In summary, the present invention provides a very practical side jamb-Weatherstrip interlocking key means.

Although the present invention has been described with reference to a preferred embodiment, it is to be understood that it is not to be so limited since changes and modifications may be made therein which are within the full intended scope of this invention as hereinafter claimed.
