WINDOW HOLDER AND OPERATOR Filed June 1, 1965 2 SheetsSheet 2 x 55' 4 56 46 Gw ye (Fl/gm United States Patent 3,357,735 WINDOW HOLDER AND OPERATOR George C. Hayman, Denver, Colo., assignor to Leslie Welding (30., Inc., Franklin Park, Ill.,"a corporation of Delaware Filed June 1, 1965, Ser. No. 460,113 7 Claims. (Cl. 292-270) The present invention relates to a novel window structure, and more specifically to a novel pushbar device for a window structure having an adjustable sash.

As will be understood, various window structures have heretofore been suggested which utilize a sash mounted in a frame for pivotal movement between open and closed positions. It has further been suggested to provide pushbar devices operable through fittings mounted on the window frame for shifting the sash between the open and closed positions. While many of such push-bar devices have been generally satisfactory, certain of such devices have been relatively difficult to mount or assemble, and certain of such devices have been constructed so as to necessitate an opening through the window frame which would permit the passage of insects or other foreign material.

An important object of the present invention is to provide'a novel window structure including a pivotally mounted sash and an extendable pushbar device con structed so that the pushbar device may be axially collapsed or extended and adjusted for moving the sash between open and closed positions without requiring an opening through frame means of the window structure which would permit the entry of insects or other foreign material.

A more specific object of the present invention is to provide a novel pushbar device adapted to be shiftably mounted in an opening through suitable fitting or guide means and adapted to be axially extended or collapsed and constructed in a manner so as to substantiallycompletely fill and seal the opening through the fitting or guide means in various adjusted positions.

A further important object of the present invention is to provide a novel pushbar device which is constructed so as to facilitate attachment thereof to a window sash orvthe like. 7

Another object of the present invention is to provide a novel pushbar device of the above described type which is of simple and economical construction and which may be easily operated or adjusted.

Other objects and advantages of the present invention will become apparent from thefollowing description and the accompanying drawings wherein: 1

Referring now more specifically to the drawings wherein like parts are designated by thesame numerals throughout the various figures, a window structure 10 I in FIGS. 1 and 2 and the closed position shown in FIG.

3. Hinge means 16 and 18 are supporting the sash within the frame.

As indicated, the frame 12 may be of any suitable construction. However, the frame preferably includes vertically extending stop members 19 and lower and upper horizontally extending

stop members

20 and 21. A 1

pushbar device 22 extends through the lower stop member 20 and is connected with the sash for manipulating the sash between the open and closed positions in the manner described in detail below.

As shown in FIGS. 2 and 6 the stop member 20 has an opening 23 therein through which the pushbar device extends and is freely slidable. A fitting or guide member 24 is secured by screws 25 to the lower stop frame member 20. The fitting is provided with a guide opening or aperture 26 in alignment with the opening 23 for slidably receiving the shown.

The pushbar is adapted to be adjusted axially to an extended position as shown in FIGS. 1 and 2 for openpushbar device 22 in the manner ing the sash and to a retracted position as shown in broken lines in FIG. 3 for closing the sash. Furthermore, the pushbar is adapted to be manipulated from the broken line position in FIG. 3 to the full line position shown in FIG. 3 for interengagement with the latch member 32 fixed to the frame member 20. The latch' member 32 may be of known construction and serves releas'ably to retain the pushbar device in the full line position shown in FIG. 3 and thereby lock the window sash in the closed position.

As shown best in FIGS. 4 through 9, the pushbar device 22 comprises a first elongated bodyor channel member 34 having a top section 35 and depending

side sections

36 and 38 terminating in inturned

flanges

40 and 42 and combining to define a generally T-shaped slot 43. A handle member 44 extends into the inner end of the slot 43 and is secured to the channel member 34 by a suitable'fastener 45. The handle member ordevice includes a block 47 which completely traverses and seals the inner end of the T-shaped slot 43.

A second elongated body or slide member 46 is provided, which body member axially slidably extends within the T-shaped slot 43. The body or slide member 46 has a transverse cross-sectional configuration substantially identical to that of slot 43 and presents oppositely extending

flanges

49 and 51 cooperatively engageable with the inturned

flanges

40 and 42 of the channel member.

As shown best in FIG. 8, the slide member 46 substantially completely fills the T-shaped slot and the bottom or exposed surface of the slide member is coplanar with the bottom or exposed surfaces of the

channel member flanges

40 and 42.

The slide'member 46 is adapted to be shifted between an axially collapsed or fully telescoped position within the channel member 34 shown in FIGS. 4 and 6 and an extended position such as that shown in FIG. 2. In order releasably to retain the slide member is a desired adjusted position relative to the channel member 34, latch means is provided between the members. More specifically, an elongated recess 54 having an inclined bottom is formed in the upper or inner side of the slide member 46 adjacent the inner end 50 thereof as shown best in FIGS. 5 and 6. A latch element 48 is secured toe a fiexure spring 52 which is mounted in the recess 54 and fixed by a fastener 56. The structure of the fiexure provided for pivotally I spring 52 is such that the latch element 48 is spaced slightly from the end 50 of the slide member 46 and is normally resiliently urged to the position shown in FIG. 6 in which the outwardly facing surface of the latch element 48 is flush with the bottom or outwardly facing surfaces of the

flanges

40 and 42 and the slide member 46, or at least does not project beyond the outer sur face of the flanges. The bottom of the slot or recess 54 provides a stop engageable with the fiexure spring 52 for limiting outward movement of the latch element 48.

The member 34 has sets of

notches

58, 60 and 62 formed in the

flanges

40 and 42 at spaced intervals as shown in FIG. 5. The

notches

58, 60 and 62 are adapted selectively to receive projecting ends of the latch element 48 for releasably locking the slide member 46 with respect to the channel member 34.

In order to adjust the slide member 46 relative to the channel member 34, an operator first presses the latch element 48 upwardly or inwardly sufficiently to disengage the latch element from the notches. Then the slide member 46 may be freely axially adjusted relative to the channel member. During such axial adjustment, the ends of the latch elements 48 will ride on the inwardly facing surfaces of the

flanges

40 and 42. The action of the flexure spring 52 is such that when the latch element 48 comes into registry with a set of the

notches

58, 60 and 62 during such axial adjustment, the latch element will be automatically snapped into such notches unless manually restrained by the fingers of the operator.

As shown best in FIGS. 6, 7 and 8, the channel member 34 has an external cross-sectional configuration of substantially the same size and shape as that of the opening 26 through the fitting 24. Furthermore, the

slide member 46 has a cross-sectional configuration complementary to that of the channel member as does the member 47 of the handle or grip element. As a result, the pushbar device serves effectively to fill and seal the opening 26 through the fitting so as to prevent the passage of insects or other foreign material therethrough. In this connection it is important to note that the latch element 48 is constructed and arranged so as to be housed completely within the channel member so that it does not interfere in any way with the margins of the fitting or guide member 24 during sliding movement of the pushbar through the fitting. In other words, there is no necessity of providing the fitting with a special notch or recess so as to obtain clearance for the latch element as is, done in certain heretofore suggested structures.

The

members

34 and 46 of the pushbar device may be formed from various materials such as wood, plastic or metal. In any event at least one of the members and preferably the slide member 46 is constructed from a resilent material so as to enable the member to bend as indicated in FIG. 2 for accommodating the swinging or pivotal movement of sash during adjustment of the sash between the closed and open positions.

The pushbar device is provided with hinge means 64 for connecting the slide member 46 to the sash member 14. The hinge means comprises a first member 66 having transverse cross-sectional dimensions the same as that of the opening '26 through the fitting so that the member 66 may also serve to seal the opening when the window is in the closed position. The member 66 has a reduced thickness portion 67 overlapping an end of the slide member 46 and pivotally connected thereto by a pivot element 68 so as to enable the slide member and channel member to be shifted between the broken and full line position shown in FIG. 3.

The hinge means has a pivot element or member 70 presenting oppositely extending pintles 72 and 74. The member 70 has a shank 76 extending into the hinge member 66 and secured thereto by a suitable fastener 78. The pintles 72 and 74 project into axially aligned apertures and 82 formed in spaced apart generally

parallel ear portions

84 and 86 of a second hinge member or element 88. The ear portions of the hinge member 88 are connected by a transverse bight portion 90 having an aperture 94 therethrough for accommodating a screw or fastener 94 used for securing the hinge member 88 to the window sash 14.

It will be noted that only a single screw is used for securing the hinge member 88 to the sash, which screw is positioned so as to be substantially bisected by a vertical plane containing the longitudinal axis of the pushbar device. In order to facilitate assembly of the screw 94, or in other words, in order to provide sufiicient clearances for the screw without increasing the size of the hinge member 88 so that it cannot fit easily within a suitable recess 95 formed in the window frame member 20, the screw accommodating aperture 94 is offset above the pintle accommodating apertures 80 and 82. Preferably the pintle accommodating apertures are disposed below a horizontal plane bisecting the

ears

84 and 86 while the axis of the aperture 92 is disposed above such horizontal plane. Furthermore, the pivot member or element 70 is formed with a recess 97 in an edge thereof facing the screw 94, which recess extends substantially through the common axis of the pintels 72 and 74. This provides additional clearance for enabling a screwdriver to be applied to the screw 94 when the hinge member 66 is swung downwardly from the horizontal position during assembly of the hinge device with the window sash.

While a preferred embodiment of the present invention has been shown and described herein, it is obvious that many structural details may be changed without departing from the spirit and scope of the appended claims.
