Feb. 4, 1958 c. SITTERLY DETACHABLE MECHANISM FOR DOUBLE HUNG WINDOW STRUCTURE United States PatiitD DETACHABLE MECHANISM FOR DOUBLE HUNG WINDOW STRUCTURE Charles K. Sitterly, Dubuque, Iowa, assignor to Carr, Adams & Collier, Inc., a corporation of Iowa Application March 7, 1955, Serial No. 492,528
Claims. (Cl. 20-522) and improved mechanism for connecting a slidable window sash to an upwardly-urged counterbalance cable including an outwardly movable hookmember carried at the upper edge of the sash adapted to engage a connecting member at the lower end of the cable so as to interconnect the sash and cable for movement together.
Still another object of the invention is to provide a mechanism for connectinga window sash slidably mounted between jamb members-tea counterbalance cable for quick and simple connection and disconnection of the parts which includes an outwardly-facing outwardly flexible hook member positioned at an upper corner of a sash and adapted to engage with a tab on the lower end of the counterbalance cable whereby to connect the sash and cable for movement together and a retainer mounted on the adjacent jamb having means thereon for selectively guiding the cable out of its normal path of movement and for engaging and holding the tab at the lower end of the cable as the sash is elevated past said retainer, said retainer means permitting re-engagement between the tab and hook member as the sash is lowered past the retainer and the hook member is deflected outwardly into the plane of the tab as it is held by the retainer.
Other objects and advantages will become apparent from the following detailed description taken in connection with the accompanying drawings, in which:
Fig. 1 is a front elevation partly in section of a window frame construction utilizing this invention;
Fig. 2 is a horizontal section taken along line 2-2 of Fig. 1;
Fig. 3 is a partial perspective view showing one of the .lower sash cables positioned in the retainer so that upward movement of the lower sash will disconnect the tab on the cable from the hook on the sash, and showing the upper sash cable in retained position after being disconnected from the upper sash; and
Fig. 4 is a perspective view similar to Fig. 3 but show- .ing the displaced hook immediately prior to and subsequent to engagement between the tab and hook.
While the invention herein described is a preferred embodiment, it is not intended to limit the invention to the specific form and arrangemcntsshown, it being contemplated that various changes may be made by those skilled in the art without departing from the spirit and scope of the' appended claims. 1
Referring now to Fig. 1 wherein is showna window I I frame, designated generally 1, and a lower sash z and n p v v a Patented Feb. 4, 1958,
an upper sash 3. Frame 1 is comprised of trim members 4, a sill member 6, an upper member 7, and side jambs 8. Secured to each jamb 8 and extending vertically the length thereof is a resilient weather strip guide means 9 adapted to readily allow removal of the sashes 2 and 3, slidably mounted therebetween, from the frame 1, as set forth hereinafter.
Each sash includes stiles 10 which have an outwardlyopening groove or recess 11 extending for at least a portion of their length. A tab holder or hook member 12 of spring steel is positioned in each groove 11 adjacent to and extending slightly beyond the upper surface of the associated stile 10. Each book member 12 is fastened adjacent its lower end to the base of groove 11 by means of a screw 13 so that the upper end may be urged away from the groove 11 but on being released will return to its normal position adjacent the base of the groove 11. The upper portion of hook member 12 is bifurcated and bent outwardly and downwardly so as to form a pair of spaced hooks or prongs 14.
Counterbalancing means are provided for the sashes and include cables 15 extending downwardly adjacent side jambs 8, the upper ends of cables 15 being operably connected to a spring-urged pulley means, designated generally 16, which may be of any well-known type and function -to exert an upward force on the cables so as to counterbalance the weight of the sash.' A tab or connector 17 is secured to the lower end of each cable 15. Eachtab 17 isadapted to be engaged by the pair of prongs 14 of the associated hook member 12 to interconnect the sashes 2 and 3 with the cables 15 for counterbalanced movement together, the engagement being such that cables 15 extend upwardly between the spaced prongs '14.
As best seen in Figs. 2 and 4, the space between hooks or prongs 14 is sufficient to allow them to pass onopposite sides of curved guide sleeve 20 when deflected outwardly from groove 11 and moved vertically past retainer member 18.
In the operation of this detach mechanism, to disconnect a sash from its counterbalancing cables 15, the sash is first moved to a position wherein the hook members 12 thereon are positioned beneath their associated retainer members 18. Portions of the cables 15 on the sash are then manually moved out of the normal vertical paths of movement of the cables and positioned in the guide sleeves 20 of the associated retainer members 18. The sash is then raised toward the retainer members 18. The operation of both hook members 12 is similar and only one will be described. As the sash is moved upwardly the upper portion of hook member 12 is gradually pulled away from the base of the groove 11 by displaced cable 15 and eventually into alignment with guide sleeve 20 on retainer member 18 as the tab 17 is engaged by guide means 20 and the tab is thereafter retained in such position as the sash is moved still further upward. The further upward movement of thegsash diseng t e defl c d-h k memb 121. m. t b:
allowing hook member 12 to spring back to its normal position against the base of groove 11; "The sash may now be moved freely upwardly andv downwardly without any counterbalancing effect or re-engagement with the tab 17 because the hookmember 12 has sprung back to its position adjacent therbase. of stile groove-11. The sash in this condition may be readily removed from. the frame in any vertical position by a sideways movement of the sash against one of the. resilient weather strip guide means 9 which disengages the other side of the sash from the other weather strip guide means v9 and, therefore, permits removal of the sash.
To re-engage the sash with its counterbalancing means, the sash is first raised to a position wherein the .hook members 12 are above the retainer members 18. .The hook members 12 are then manually urgedoutwardly from their normal positions and into the plane of the cable tabs 17 retained by theretainer members ,18. .The sash is then moved downwardly so that 'the books, 14 move past guide sleeves 20 on retainermembers 18.and into engagement with retained cable tabs 17, thersash now being again connected to its counterbalancing. means. The cables 15 are then manually removed fromrguide sleeves so that they are'no longer deflected fromtheir normal vertical paths of movement, the movement-of the sasIh now being properly counterbalancedas desired.
