TENSIONED LOCKING DEVICE FOR. LOUVRES AND THE LIKE Filed July 5, 1964 INVENTOR.

THOMAS G SCONZO ATTORNEY WWWWW,

United States Patent 3,296,740 TENSIONED LOCKING DEVICE FOR LOUVRES AND THE LIKE Thomas G. Sconzo, Macon St., Sayville, Long Island, N.Y. 11782 Filed July 3, 1964, Ser. No. 389,140 2 Claims. (CI. 4987) This invention relates to a tensioned locking device for window frame construction and more particularly to an adjustable locking device for jalousies and the like types of window and door construction wherein a portion thereof can be opened and fixedly maintained in locked position.

The invention herein is an improvement of my invention described and claimed in US. Patent No. 2,905,984, dated September 29, 1959.

In the types of jalousies heretofore used, it is to be noted that there is provided an operating leverage mechanism for opening and shutting the louvres constituting the jalousie. Such controlled operating mechanism is usually and preferably disposed at one side only of the jalousie frame and at the lower portion thereof for facility of use. It has been noted, however, that said operating mechanism does not close the window panes or louvres tightly on the side opposite the mechanism. In fact, there usually is, at the end of the louvres or panes away from the operating mechanism, a space between such louvres or panels when closed thus permitting air, wind and rain to come through such space because of the uneven locking of the louvres. Various types of control units have been used wherein there are double handles or screw mechanisms which however, have not been very effective.

With the above disadvantages in view, it is an object of my invention to provide a fool-proof uniform pressure locking mechanism in a window or door frame construction to effect a uniformly tight closing of the louvres or panes at the portion away from the operating mechanism.

Another object of the present invention is to provide a controlled camlock device for installation on the side of a jalousie frame to act as an auxiliary to the regularly used types of operating closing mechanisms so as to effectively close the louvres or panes of the jalousie and form a uniform seal at the contacting portions of the louvres or panes.

Still another object of the present invention is to provide a tensioned, adjustable, regulatable auxiliary locking camlock device having a series of engaging sections in the device adapted to uniformly close or lock the louvres or panes in unison thus forming a seal between the adjoining louvres or panes when in closed position.

A more specific object of my invention is to provide a manually operable, easily installable, adjustable locking mechanism for easy connecting with an operating bar of a jalousie frame for effectively closing the ends of the jalousie panes and form a tight seal thereat.

Other objects and features of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings, wherein:

FIG. 1 is a sectional broken away side view of a jalousie frame construction embodying a preferred form of my invention;

FIG. 2 is a sectional enlarged view taken on line 22 of FIG. 1;

FIG. 3 is a sectional view taken on line 3-3 of FIG. 2;

FIG. 4 is an exploded view of the components embodying FIG. 2; and

FIG. 5 is an enlarged view of a part of the embodiment shown in FIG. 4.

Referring now specifically to the drawings wherein like numbers refer to like parts throughout, it will be noted that such jalousie may be for a window or door type of construction. In said frame piece 13, there are provided jambs 14 one on each side of the piece for accommodating individual louvres or jalousie panes 15 mounted in suitable retaining members 16 at each end thereof, which retaining members are pivoted to the jamb 14 by means of pin members 17. Extending at an angle from said retaining members are linkage arms 18 which in turn are pivota-lly connected at 19 to an operating arm 20 which in turn extends substantially parallel to the major length of the jamb 14. Said arm 20 because of its leverage controls the movement of panes 15 via linkage arms 18.

Said ope-rating arm 20 it will be noted from FIG. 1 of the drawing is in turn pivotally connected preferably at its lower portion, to a pivoted rod 21 which extends diagonally downwardly and is connected to a manually operable arcuately shaped adjustable locking member 22. Said rod 21 is pivoted to said lock member by means of a pin 23.

Member 22, it will be noted comprises two portions, one a straight link 24 which is connected at one end by means of pin 23 to member 21 while at its other end it is provided with a cross pivot or pin 25. The other portion 26 is curved and provided with a plurality of notches or indentations 27.

A housing 28 consisting of two

engageable sections

29 and 30 form a hollow for accommodating said locking member 22. Also, the housing is adapted to accommodate the member 22 and link 24, which is movable therein. Portion 29 has

extensions

31 and 32 for attachment to jamb 14 as shown in FIG. 1 by means of bolt or screw members 33.

Section 29, furthermore is provided on its side with a vertical slot 34 and a threaded opening 35, while section 30 is a plate engageable with section 29 and has

extensions

36 and 37 which fit into

grooves

38 and 39 respectively. Section 30 also has an internally disposed side extension 40 with a threaded opening 41 which is in alignment with opening 35 for accommodating screw 42 so as to hold said

sections

29 and 30 together in joined condition as shown in FIGS. 1 and 2. Furthermore, section 30 has a slot 43 which with slot 34 accommodates pin 25 which is slidable therein.

It will be noted that section 30 provides a housing for a block 44 and a spring 45. Said block as shown in FIG. 5 is of such shape as to fit in a recess 46 and held in position when said sections are joined. Spring 45 fits inside an opening 47 in block 44 and rests at one end against a floor 48 so as to keep said block 44 under tension. Said block 44 furthermore, has a protruding riding portion 49 on which the inner portion of arm 22 rides as shown in FIG. 3. Said spring exerts sufiicient pressure to maintain arm 22 in any fixed position against the top 50 and extension 31 to form a tight look when arm 22 is moved.

Also, pressure can be applied against said arm so that pin 25 can be moved vertically in slot 34-43 against the pressure of spring 45 in the housing. Said arm can be moved in a limited are about pin 25 as a pivot so as to actuate rod 21 to open or close the panes 15. The arm 22 can be moved about pivot 25 so as to engage edge 48 with any of the notches. The tension on spring 45 is of sufficient force to hold the arm 26 in any set position.

In operating the device, the handle or curved member 26 is moved around pin 25 so that the pressure applied on said member 26 causes the inner curved part of the arm to ride on portion 49 of block 44 and against the pressure of, spring 45.

Notches 27 provide stops and also prevent further movement of the arm 26 unless pressure is applied thereon to overcome the pressure of spring 45 against block 44.

Furthermore, it will be noted that a wedge 42a is provided which fits in the cavity 425. Said wedge can be adjusted by screw 42 and moved toward or away from the rounded portion of link 24 whereby said link is raised or lowered on its pivot pin 25. By such use of wedge 42a, the pressure of portion 26 against recess 46 can be regulated. In order to facilitate the sliding movement of link 24 on pin 25 against wedge 42a there is provided a groove 420 in said Wedge.

While a preferred embodiment of the invention has been illustrated and described herein it is to be understood that various modifications as to form, arrangement of parts and use of materials may be made without departing from the spirit and scope of the invention as claimed herein.

I claim:

1. An auxiliary locking device for operating a movable member for louvres for tightly closing louvre panes and the like in a jalousie construction, comprising a housing attachable to one of the jambs of the jalousie construction, said housing having an opening therein, a notched movable elevating and depressing arm extending through said opening of the housing pivotally connected at one end to the movable member for the louvres, said arm further having an extending portion pivotally connected in the housing, said extending portion being connected intermediate the ends of said movable arm, means at the extending portion for pivotally retaining said arm, riding tensioned means in the housing for the pivoted arm in the housing, said notched arm engaging the housing to permit setting of said arm, said housing being provided with a movable wedge to regulate the movement of the extending portion.

2. A device according to claim 1 wherein the housing has a set screw and the wedge is movable by said set screw in the housing, and the wedge has a grooved channel to accommodate the end of extending portion.
