WINDOW Filed May 9, 1968 2 Sheets-Sheet 2 BA/aey Ewe/95 nited States Patent U.S. Cl. 49150 8 Claims ABSTRACT OF THE DISCLOSURE A window comprising a frame and at least one movable sash. The sash is slidably mounted in the frame through sash mounted retractable means permitting the sash on retraction of some of the means to be swung relative to the frame or on retraction of all of the means to be removed from the frame.
This invention relates to windows having one or more vertically slidable sashes, either weight balanced, spring balanced or in the case of some pairs of sashes contrabalanced, which can be opened and closed as hitherto. The invention has been devised to provide such windows wherein the respective sashes can:
(a) Be swung in the frame inwardly as for cleaning purposes,
(b) If desired, be supported in the frame in a swungout position or a swung-in position for ventilation purposes,
(c) Be easily removed from and replaced in the frame without the use of tools.
According to this invention the window comprises a frame and at least one sash slidable in said frame, the jambs of said frame each having at least one longitudinal track in the face opposite the other of said jambs, said slidable sash being narrower from stile to stile than the distance between said jambs; said sash having a pair of sash supporting members adjacent each of its ends, the members of each pair being mounted in the respective stiles of the sash, the members of one of said pairs of members being runners directly engageable in and disengageable from said jamb tracks and the members of said other pair having pegs engageable in and disengeable from runners permanently slidably mounted in said tracks, said sash being swingable about the axes of said pegs after disengaging said sash mounted runners from said tracks and being removable from said frame after swinging by disengaging said pegs from said jamb mounted runners said jamb mounted runners being adapted to be locked against sliding movement by the swinging of said sash.
The invention will be described by way of example as applied to a double hung counter weighted window with reference to the accompanying drawings wherein:
FIGURE 1 is an exploded perspective view of the window,
FIGURE 2 is a fragmentary sectional view of the end of a sash member incorporating one of the sash mounted runners,
FIGURE 3 is a fragmentary perspective view of a stay member which can be incorporated in either or both sashes to stay them in a swung position for ventilation purposes, and
FIGURE 4 is an enlarged detail view of the jamb mounted runners as depicted in FIGURE 1.
As illustrated the window frame jambs 1 are made as rectangular casings to accommodate upper and lower sash weights 2. The back wall 3 of each jamb has an arrangement of key flanges 4 thereon to facilitate mount- 3,473,262 Patented Oct. 21, 1969 ICC ing in a building and/or to connect one window frame to another. The front wall 6 of each jamb is flanged outwardly a short distance as at 7. There is a longitudinal gap between the flanges 7 and the flanges 7 each have a tapered edge catch 8 formed thereon. The front wall 6 of each jamb has a plate 9 having catches 10 complementary to and adapted to engage the catches 8. Each plate 9 has two longitudinal tracks 11 formed therein with mturned flanges providing therebetween narrow entrances 12 to said track. The upper and lower ends of the front plates 8 fit onto curved complementary fillet junction pieces 13 which join the head 14 and sill 15 to the window frame jambs 1.
The sashes are made as U frames 16-17 with a rail 18 joining the ends of the limbs of the respective Us. Each sash has a glazing recess 19 formed therein. The outer edge of the U members each have three grooves 20-21-22 therein. The two outer grooves 20-22 are constructed to receive arrowhead legs 23 of an arcuate section weather anti-rattle strip 24 made of elastomeric or other resilient material.
Each sash has a pair of runners 25 slidably mounted one in each end of the rail 18. The runners 25 each comprise a body 26 having a spring receiving recess 27 open at one end and one side. The body has a finger 28 projecting from its other end and a finger grip 29 projecting upwardly from its open side. Each rail 18 is of hollow rectangular metal section with two legs 30 on one face 31. The space between the legs 30 is aligned with and acts as a continuation of the glazing recess 19 of the U member. The hollow of each rail accommodates the bodies 26 of the runners 25. There is a slot 32 in the rail face 31, the slot 32 slidably accommodates the fingergrip 29. A lug 33 is pressed from the face 31 of the rail 18 and is bent down into the interior of the rail to provide an abutment face for a spring 34 located between the lug 33 and the end of the spring receiving recess 27 of the runner body 26. The finger 28 has an end groove 35 to give clearance to a balance weight support cable and chamfered edges 36 to facilitate the entry of the finger 28 into the track 11. The runners 25 are retained in operative position between the spring 34 and end stop 37 made of elastomeric material which act as a continuation of sealing strip 24 by screws 37A. The end stops each have a hole 38 therethrough through which the finger 28 of the associated runner 25 projects.
Adjacent the base of the U on each leg there is a bowed leaf spring 39 having holes 40 at one end whereby the spring is fixed by screws 41 to the bottom of the groove 21. At the middle of the bow in the spring finger 39 there is fixed a square cross sectional peg 42 (which projects through the weather strip 24). The peg is removably mounted in an oval bush 43 which engages in a runner block 44 made of nylon. The runner block 44 has a body which is generally square in cross section and is dimensioned to slidably fit the track 11. There is a longitudinal parallel sided projection 45 on one face of the block, the width of the projection 45 is substantially the same as the width of the opening 12 in the plate 9. As the block body is wider than the opening 12 the block 44 is permanently retained in track 11.
The block 44 has a medially positioned hole 46 through it and grooves 47 extending from the ends of the hole to one end of the block. The hole 46 and grooves 47 are for the connection of a weight supporting cable to the block 44. There is a hole 48 through the block 44 near its other end, the axis of the hole 48 is normal to the face of the projection 45 and extends therethrough. The hole 48 is oval with the long axis of the oval aligned with the long axis of the block 44. A slot 49 bifurcates the block 44 and extends from the adjacent 3 end of the block to intersect with the hole 48 thereby forming two flexible legs 50. It will be appreciated that when the oval bush 43 and the mating oval hole 48 have their corresponding axes aligned the legs 50 will be parallel whereas if the bush 43 is rotated 90 from this position the legs 50 will be forced apart and thus grip the sides of the track 11.
A conventonal cam type lock '51 is fitted to the rails 18 and conventional sash raising grips 52 are fixed to the sash 17. Four sash weights 2 coupled by cables 53 to the blocks 44 and running over pulleys 54 mounted on pins 55 in the junction pieces 13 completes the essential component parts of the window.
The sashes are slidably supported by means of the runners 25 and 44 engaging in the tracks 11 and are counter balanced by the sash weights 2.
To remove a bottom sash or to release one end of that sash the first operation is to exert pressure on finger grips 29 of runners 25 thereby extracting fingers 28 from the tracks 11. The released end of the sash can then be swung out of alignment with the jambs. The swinging of the sash rotates the oval bush 43 causing the legs 50 of the runners 44 of the bottom sash to separate and bind against the sides of the tracks 11. In this Way the runners 44 are locked in position so preventing the sash weights 2 falling, when, as a subsequent operation if the sash is to be removed-the bowed leaf springs 39 are deflected thereby extracting pegs 42 from the oval bushes 43. The bushes 43 remain locked in the holes 48 of the runners 44 while the sash now free from the jambs can be removed. The upper sash can be removed in a similar manner. The sashes can be remounted in the jambs by reversing the foregoing procedure.
Provision may be incorporated whereby either or both sashes can be secured at an angle relative to the jambs as for example to provide for night ventilation. This is made possible by spring arms 56 each pivotally connected to a bracket 57 fixed to the rails 18 and each having a roller 58 engageable in a track 11. The runners 25 are disengaged from the tracks 11 allowing the sash end thus released to be moved away from the jambs for a distance equal to the length of the arms 56.
I claim:
