- FIG. 4 is a plan view of the embodiment of FIG. 3 shown in the open position
- FIG. 5 is a side view of the operating components of the embodiment of FIG. 3.
- FIG. 6 is a partial plan view illustrating the present invention installed in an open configuration.
- FIG. 1 One embodiment of the present invention is shown generally in FIG. 1 in association with a casement window which is movable between a closed position and an open position. It will be apparent to a skilled artisan with an understanding of the present invention, however, that this invention can be used with many other types of windows (including, for example, awning windows) as well as other closures.
- the casement window as shown in FIG. 1 has a window frame 10, a window sash 11, and a sash lock 12.
- a casement window operator 13 is provided having a base 14 which is mounted to the window frame.
- the operator 13 includes a mechanical deployment linkage 16 extending between the window frame 10 and the base 14, and a lock linkage 18 engaged with the deployment linkage 16 and coacting with the sash lock 12.
- a worm gear 20 drivingly connects a rotatable handle 22 with the deployment linkage 16 (see FIG. 6).
- the deployment linkage 16 comprises a slider 24, a drive linkage 26, and a support link 28 (see especially FIG. 6).
- the drive linkage 26 includes a drag link 30 having oppositely spaced ends 30a, 30b and a gear arm 32 having one end 32b pivotally connected to one drag link end 30b.
- the other gear arm end 32a includes gear teeth 32c which engage the worm drive 20.
- the slider 24 is disposed intermediate the window sash 11 and the window frame 10.
- the support link 28 is pivotally connected between the window sash and a pivot 29 fixed with respect to the window frame.
- the lock linkage 18 includes a plurality of rigid links which are pivotally engaged with the deployment linkage 16 and thereby in driving engagement with the rotatable handle 22.
- a lock linkage gear lever 36 has an end portion 36a which is pivotally connected to the toothed end 32a of the gear arm 32 at a free pivot 33 and pivotally connected relative to the base, 14 at a fixed pivot 38.
- An oppositely spaced end 36b of the gear lever 36 has a projecting portion or tab 36c.
- a lock linkage transmission link 40 is pivotally connected to a fixed pivot 42 and is further connected to the gear lever 36 by a lock linkage intermediate link 44.
- a linear motion-transmitting tie bar or rod 46 is pivotally connected to the transmission link 40 and coacts with the sash lock 12. Specifically, motion of the tie rod 46 to the left in FIG. 1 will engage (lock) the sash lock 12, and motion of the tie rod 46 to the right in FIG. 1 will disengage (open) the sash lock 12.
- the sash lock 12 illustrates merely one exemplary lock which could be used with the present invention. Any sash lock which can be opened and closed in response to such linear motion of the tie rod 46 would be suitable.
- a bolt lock having bolts which project into (and retract from) openings in the window sash to lock (and release) the window would also be suitable where an appropriate linkage between the bolts and tie rod is provided.
- still other suitable sash locks would be recognized by any person of average skill in the art as being appropriate for use with the present invention.
- the operator 13 includes a trip lever 48 pivotally connected to a pivot 49 on the base 14.
- the trip lever 48 includes a trigger 50 and a recess 52 for receiving the gear lever projecting tab 36c.
- a compression spring 54 having one end fixed to the base 14 biases the trip lever 48 toward the gear lever projecting tab 36c.
- the trip lever 48 is configured so that the trigger 50 extends beyond the window frame 10 when the projecting tab 36c is in the trip lever recess 52.
- a suitable stop (such as the stop 56 shown) may be provided on the window sash 11 so as to facilitate engagement with the trigger 50 when the window sash 11 is closed as described below.
- the basic operation of opening and closing the window is accomplished by the operator turning the handle 22.
- the handle 22 and its connected worm gear 22 are turned to produce a clockwise rotation of the gear arm 32.
- the forced rotation of the gear arm 32 induces tension force in of the drag link 30.
- the slider 24 is urged along the frame 10 toward the fixed pivot 29 (to the right in FIG. 6). This motion also induces forced clockwise rotation of the support link 28 and results in the window sash 11 being outwardly rotated and the window thus being opened.
- the handle 22 is rotated in an opposite direction whereby the drive linkage 26 is oppositely actuated and forces the slider 24 away from the fixed pivot 29 to inwardly rotate the window sash 11.
- the sash lock is automatically opened and closed as appropriate as described below.
- the compression spring 54 biases trip lever 48 to the position shown in FIG. 1, with the trigger 50 extending beyond the window frame.
- the stop 56 engages the trigger 50 and rotates the trip lever 48 counterclockwise about the pivot 49 to free the gear lever tab 36c from the trip lever recess 52.
- FIG. 2 An alternative embodiment of the present invention is shown in FIG. 2.
- the FIG. 2 embodiment is similar to that shown in FIG. 1, and thus components which are comparable to those in the FIG. 1 embodiment are given the same reference numerals but plus one hundred in FIG. 2 (for example, the gear lever is identified as "36" in FIG. 1 and "136" in FIG. 2).
- the lock linkage 118 has a cam 141 with an arcuate slot 143 extending therethrough.
- the cam 141 is pivotally connected to the base 114 at a pivot 145.
- the gear lever 136 has an outward extending pin 136' which is received by the slot 143 of the cam 141.
- This embodiment thus provides operation similar to that described with respect to FIG. 1 except that, in the FIG. 2 embodiment, movement of the tie rod 146 is controlled directly through the cam 141 by the coaction of the pin 136' in the cam arcuate slot 143.
- This embodiment offers the benefit of fewer parts and increased simplicity.
- FIGS. 3-5 Yet another embodiment of the present invention is shown in FIGS. 3-5.
- This embodiment is similar to the previously described embodiment, and thus discussion is had here only with respect to any significant differences found with this embodiment. Further, components in this embodiment which are comparable to those in the FIG. 1 embodiment are given the same reference numerals but plus two hundred in FIGS. 3-5 (for example, the gear lever is identified as "36" in FIG. 1 and "236" in FIGS. 3-5).
- the FIG. 3-5 embodiment includes a lock linkage 218 adjacent a deployment linkage 216 and having a gear lever 236 and a lock link 234.
- a motion-transmitting tie rod 246 is pivotally connected to the lock link 234 and engages a suitable sash lock 212.
- a trip lever 248, with an integral trigger portion 250, is pivotally connected to the lock linkage at a pivot 280.
- a tension spring 254 is connected between the trip lever 248 and the base 214.
- a rotatable fastener 80 is provided at the union of the lock link 234, the gear lever 236, and the trip lever 248. As best shown in FIG. 5, the rotatable fastener 80 has a plurality of eccentric shoulders 80a, 80b, 80c.
- the lock link 234 and gear lever 236 have cylindrical openings 235 and 237, respectively, which pivotally receive the first and second fastener eccentric shoulders 80a and 80b, respectively.
- the trip lever 248 has an opening 249 which receives the keyed fastener shoulder 80c such that the trip lever 248 is precluded from pivoting relative to the fastener 80.
- the fastener 80 further includes a head 81 for precluding axial disengagement of the joined members.
- the angular position of the trip lever 248 defines the orientation of the gear lever 236 and lock link 234.
- the eccentricity of the shoulders establishes a complex circumvolutory motion of the three pivoted elements about the joint 280 when the trip lever is rotated.
- opening the window is accomplished by applying a rotational force to the handle, whereby rotational forces are imparted to the deployment linkage 216 such that the sash 211 is pivotally opened as detailed above.
- a force is applied to the handle whereby the deployment linkage 216 is oppositely actuated so that the sash 211 is pivoted toward the window frame 210.
- the trip lever 248 While the window is unlocked, the trip lever 248 is arranged as shown in FIG. 4 with the trigger 250 extending upwardly (and the tie rod 246 biased fully to the right to maintain the sash lock in an open [retracted] position).
- the trip lever 248 is forcibly pivoted.
- the operator of the present invention can be easily operated when installed. Operation provides virtually foolproof security inasmuch as the window is automatically locked when closed (and unlocked when opened) without requiring any additional action by the operator. Therefore, there is no danger of a window being left unlocked because the operator forgot to take the additional action required to lock it.
