SLATTED SHADE ASSEMBLY HAVING STORM BAR MEANS This application invention is a continuation-impart of my copending application Ser. No. l47,43l filed May 27, 1971 now U.S. Pat. No. 3,732,913.

This invention relates generally to slatted shade assemblies, and more particularly concerns new and improved storm bar means for such assemblies.

Slatted shade assemblies, and more particularly those which are installed in storm-prone geographical areas have the disadvantage that due to their generally light weight construction, they are rather prone to damage in stormy weather, and more particular weather on the order of hurricane force. Not only do storm winds of the magnitude tend to blow such curtains inwardly,'but also outwardly, depending upon the direction from which the wind is blowing, as well as tendency of such wind to change direction or blow with a substantially pulsing force. Not only is there the liability of damage to the shade assembly, but if the curtain slats break loose they may be driven with damaging force against other objects and possibly also become lethal missiles as propelled by the force of high velocity wind. Heretofore, no adequate means have been provided against these dangers, and instead of utilizing the shades for storm protection, it has generally been necessary to roll up the shades on threat of damaging storm.

An important object of the present invention is to overcome the foregoing and other disadvantages, deflciencies, inefficiencies, shortcomings and problems encountered in prior slatted shade assemblies and to attain important advantages and improvements as will hereinafter become apparent.

Another object of the invention is to provide new and improved storm bar means for slatted shade assemblies.

A further object of the invention is to provide new and improved storm bar means for shade assemblies which will retain the shades against wind pressure against either face of the shade.

Still another object of the invention is to provide dual storm bar protection for slatted shade assemblies.

Yet another object of the invention is to provide a new and improved storm bar and retaining clip combination for slatted shade assemblies.

Other objects, features and advantages of the invention will be readily apparent from the following description of certain preferred embodiments thereof, taken in conjunction with the accompanying drawings although variations and modifications may be effected without departing from the spirit and scope of the novel concepts embodied in the disclosure, and in which:

FIG. I is an inside elevational view of a roll-up slatted shade assembly as shown in my parent application Ser. No. 147,431 (Supra).

FIG. 2 is a fragmental sectional elevational view showing features of the roll-up roller of the shade assembly as shown in said parent application.

FIG. 3 is a fragmental sectional elevation view taken substantially along the line IIIIII of FIG. 1.

FIG. 4 is a fragmental vertical sectional elevation view showing a modified arrangement of the storm bar means embodying important features of my invention.

FIG. 5 is a fragmentary horizontal sectional view taken substantially along the line VV of FIG. 4.

FIG. 6 is a fragmental elevational view taken substantially in the plane line VIVI of FIG. 4.

Referring, by way of example, to FIGS. 1, 2 and 3, a slatted shade assembly 10 is depicted embodying features of the invention shown in my parent application and comprising a screen made up of a series of horizontal slats 11 made from suitable form-retaining sheet material such as sheet metal which may be aluminum, stainless steel, sheet steel, synthetic plastic, and the like, having any preferred finish and made according to any preferred process such as rolling, extrusion, or other preferred technique, and desirably of a standard structure so as to be capable of ready adaptability for length and width of screen to suit installation requirements. Preferably each of the slats 11 is of as advantageously thin material for light weight, consistent with adequate strength for the purpose, provided with a transversely bowed body affording at least some aid in form retention of the slat and desirably arched toward the outside of the screen. Along the respective opposite upper and lower edges of each of the slats 11 are pro vided respective partially closed reinforcing

bead curls

12 and 13. The upper curl 12 is turned toward the outerside of the slat and the lower curl 13 is turned toward the inner side of the slat, and each curl has a terminal edge which is at least slightly spaced-from the body of the slat so-that by effecting an interhooked relation of the upper curl of one of the slats with the lower curl 13 of another slat a coactive mutually supporting hingedly connective relation of the slats in the screen is attained. Assembly of the reinforcing and hinge curls 12 and I3 is readily effected by an endwise sliding relative assembly movement of the slats.

By preference, the slatted shade is supported by a head sub-assembly 15 for vertical raising and lowering movements in vertical tracks provided by means comprising respective left and right hand (considered from the inside of the unit 10) vertical guide tracks provided by

bars

17 and 18 which are desirably formed as aluminum extrusions and disposed in assembly in allochiral relation. At their lower ends the

bars

17 and 18 rest upon a base plate 19 secured as by means of lag bolts 20 to a floor 21 and having along its inner edge an upstanding flange 22 to which the bars are secured as by means of screws 23.

In the present instance the head assembly 15 is supported on the upper end of the

bars

17 and 18 by means of upstanding arms 24 secured to the bars as by means of screws 25 and at their upper ends supporting respective aligned

shaft elements

27 and 28 secured thereto as by means of screws 29 and rotatably supporting a roller 30 which is normally biased by means of a coiled torsion spring 31 in a roll-up direction. The upper endmost of the slots 11 is suitably secured fixedly to the roller 30.

Vertical movements of the slatted shade between open raise position and closed lower position are guided within respective track grooves 32 in the

bars

17 and 18 defined by respective inner side vertical flanges 33 and outer side vertical flanges 34 which are provided at their upper ends with divergently flaring portions to define at the top of each track groove or channel an upwardly opening throat 35 to facilitate movement of the slatted shade into and out of the track channels as rolled up or drawn from the roller 30.

At its lower end the slatted shade is provided with a horizontal pull bar 37 which at its ends rides in the track channels 32 and is desirably provided with a central inwardly projecting generally U-shaped handle 38 secured thereto as by means of screws 39. Means for holding the shade in closed position desirably comprise respective removable locking pins 40 adapted to the manipulated by means of angular handles 41 into and out of registering'keeper openings in the lower end portions of the flanges 33 and end portions of the bars 37 or respective latching fingers 42 which lap the flanges 33 and are secured to the pull bar 37 as by means of screws 43. In the open condition of the shade it is held at the ready at the top of the track bar frame by engagement of the latching fingers'42 as stops with respective stops 44 secured to the upper end portions of the track bars as by means of the screws 25 by which the arms 4 24 are attached to the track bars. For additional locking security and to provide thorough hurricane or other storm resistance to inward displacement of the closed slot curtain, replaceable means are provided in the form of a back-up device comprising a separable T- frame 45. This comprises a vertical rigid bar 47 of preferably L-shaped cross-section having its lower end portion shaped to provide a finger 48 to clear through the handle 38 located centrally of the bar 37. In addition, the lower end finger 48 of the bar 47 is constructed to fit in behind the flange 22 of the base plate and may be equipped with a snugging filler piece 49. At its upper end portion, the vertical bar 47 is separably secured to a generally inverted L-shaped cross-section horizontal head bar 50 which is of a length to be engaged with its vertical flange within the throats 35 of the

track bars

17 and 18 and resting with its inturned horizontal flange portion on the upper ends of throat flares 51 of the inner bar flanges 33. Replaceable attachment between the

bars

47 and 50 is effected by means of a wing nut screw 52 which is secured through the vertical flange of the bar 50 and an angled upper terminal flange 53 attached as by means of rivets 54 to the upper end of the bar 47. Through this arrangement, assembly of the T-bar structure with the shade assembly 10 is easily effected by mounting the head bar in place and then mounting the bar 47 in place and securing it to the head bar as by means of the fastener 52. Inward pressure against the slat curtain will thus be thoroughly resisted not only by the track bar flanges 33, but also by the T frame 45. In addition, should there be any tendency for the locking pins 40 to dislodge or work loose, the storm bar 47 will positively hold the shade closed by means of a shoulder 55 which overlies and will be engaged by the handle 38 adjacent the upper end of the finger 48.

/ I along.

Also for this purpose, a felt, elastomeric sponge material 58, or like cushioning material is carried by the back surface of the vertical bar 47, preferably throughout its length below the head bar. The cushioning material 58 is of sufficient thickness to press lightly but without deforming pressure against the slats 11, a greater compression pressure being permitted at the pull bar 37.

Where insect screening is employed with the shade assembly, the screening will be mounted outside the shade assembly so that the shade assembly can be operated from the interior of the screened-in space.

In FIG. 4, 5 and 6 a modified improved arrangement of a storm bar structure is disclosed which, among other things, provides assurance against whipping or pulsating displacement of the slatted shade under severe storm conditions. Insofar as details of the shade assembly itself are concerned, they are substantially the same as in FIG. 1, but means are depicted for securing a plurality of shade assemblies 10' in edged-to-edge relation if desired. For example, at contiguous sides of the respective assemblies 10', outwardly projecting flanges 56 (FIG. 4) longitudinally along the sides of the track bars 171 and 181 are secured as by means of screws 56a to vertical supporting frame bars 59 of generally T-cross-section having their leg flanges secured to and between the flanges 56 of the track bars and extending from the base plate 19 to a ceiling 60 to which the upper ends of the bars 59 are secured as by means of angle brackets 61 by means of bolts 62, the brackets being secured to the ceiling as by means of screws 63. In a desirable arrangement, the bars 59 extend to a substantial extent upwardly beyond the ends of the

track bars

17 and 18 and well above the roller 30 for the curtain slots 11'. To close the gap above the shade assembly, a valance panel 64 may be secured along the outer side of the gap to and between the frame post bars 59.

A locking security and storm'bar device 65 comprises a rigid vertical bar 67 which is constructed and arranged to be placed replaceably vertically along the central inner side of the slotted curtain similarly as is the bar 45. However, the bar 67 is desirably constructed as a hollow rectangular tubular member which desirably comprises a length of extruded aluminum section of the desired dimensions providing utmost rigidity for its size and yet being relatively light in weight for easy handling and storage when not in use.

At its lower end, the bar 67 is provided with a downwardly opening notch 68 providing a downwardly extending finger 69 along one edge of the bar adapted to engage through the handle 38' into space between the upstanding flange 22 of the base panel 19 and the pull bar 37. At its upper blind end the notch 68 provides a downwardly facing shoulder to retain the handle 38 against unintentional upward movement and thereby locks the slatted shade against opening during a storm should any other locking or latching means for the shade fail.

Attachment of the storm bar 67 in operative position is effected by releasable securing means such as a thumb-screw 70 at the upper end portion of the bar to a depending flange ofa bracket 71 which is secured as by means of rivets 72 to the underside of an inwardly projecting horizontal flange or leg 73 of a horizontal angular crossbar 76 of generally L-shaped cross-section having a depending flange or leg 74 secured as by means of the screws 25' to the flanges or inside faces 33 of thevertical track bars of the associated shade assembly 10'. In this instance the cross-bar is secured permanently to the upper end portions of the track bars and can serve as an upward stop for the slatted shade, with the handle 38 engaging the depending flange 74 to stop upward opening movement of the shade when it has reached the desired fully open position. The bar 76 therefore has a double utility in this arrangement. The placement of the storm bar 67 as needed is very easily effected by placing the bar 67 and attaching it by means of the screw 70. Likewise removal of the storm bar is simply effected by releasing the wing nut screw 70 and removing the bar for storage. A layer of suitable sound proofing, cushioning material 75 is desirablyprovided on the edge face of the bar 67 which opposes the slots 11.

Means are provided to assure retention of the slatted screen against whipping, drumming or deflecting away from the storm bar 67 under wind pressure. ln other words, the arrangement is such that not only is the shade screen held against inward deflection by the bar 67 but it is also held against outward deflection. As a highly desirable structure for attaining retention of the screen against outward deflection, locking plates 77 are mounted on the bar 67 preferably at one side and at as many places at longitudinally spaced intervals thereon as desirable for the particular installation and the type of weather conditions to be anticipated. For example, one of the plates 77 may be placed at each twenty inch spaced interval vertically along thebar. Each of the plates 77 comprises a flat elongated member having along one longitudinal edge a plurality of similar hooklike retaining tooth or finger projections 78 which are shaped to engage in interlocking relation with the tops of the hinge curls 12' and to fit partially down into the tolerance gap afforded by the lower hinge curls 13. For this purpose the retaining projection fingers 78 are spaced apart about equal to the width of the slats 11' and are directed downwardly so as to be automatically lockingly engageable with the slat hinge joints when the storm bar 67 is mounted in its operative relation in the assembly.

In order to facilitate handling of the storm bar 67 before installation and also to facilitate installation adjustment of the locking plates 77, they are preferably secured to the side of the storm bar 67 at the factory in a retracted relation as shown in dash outline in FIG. 4 and are then adjusted into the optimum operating position relative to the bar and to the slat screen on the installation site. For this purpose, the plate 77 is provided with a pair of identical vertically spaced dog-leg slots 79 through which the shank of a respective retaining screw 80 is received and tapped into the side of the bar 67. In the retracted position of the bar the screws are engaged in horizontal respective legs of the slots 79 as shown in dash outline, and then whenv the bar is installed, the screws 80 are loosened and the plate adjusted by shifting it outwardly relative to the outer edge of the bar 67 until the desired engagement with the slats 11 is effected, the diagonal upwardly and inwardly directed inner leg of the slats 79 accommodating optimum adjustment of the plate 77. When such optimum adjustment has been attained, the screws 80 are thoroughly tightened to hold the plate 77 in permanent readiness for locking engagement with the screen as an incident to placing of the storm bar-67 in operative position as needed. It will be observed that the location and disposition of the retaining fingers 78 is such that they will enter into engagement with the slat hinges as an incident to the normal downward and outward assembly movement normal to placing the bar 67 in position, wherein the finger 69 is first introduced into the handle 38 by downward and outward movement and then the bar swung outwardly into the final assembled position wherein the wing screw is placed to secure the bar in 67 to the horizontal bar 76.

Alternatively to the use of the interlock plates 77, means for holding the curtain of the shade assembly against displacement movement in opposite direction to the bracing against displacement movement provided by the storm bar 67, may be provided in the form of a generally complementary outside storm bar 81 (FIGS. 4 and 5). This may be in the form of an aluminum extrusion of generally H-cross-section and of a length to extend between the base flange of the base plate 19 to an angular horizontal head bar 82 secured to and between the upper end portions of the track bars 17' and 18' as by means of screws or rivets 83. For replaceably attaching the storm bar 81 at about the vertical center axis of the slat curtain, opposite the storm bar 67, an angle bracket 84 is secured as by means of rivets 85 at the proper location on the underside of the head bar 82, with a wing head thumb-screw 87 provided for releasably securing the upper end portion of the storm bar 81 to the bracket 84. At its lower end, the storm bar 81 is anchored to the base plate 19' by means comprising an angle bracket 88 secured as by means of rivets 89 to the base plate and providing an upstanding flange to which the lower end portion of the bar 81 is secured by means of a wing head thumb-screw 90. Cushioning and sound deadening means in the form of a suitable strip of material 91 is desirably provided on the face of the bar 81 which confronts the screen. By having the outer storm bar 81 slightly shorter than the inner storm bar 67 and the head or crossbar 82 at a slightly lower elevation than the inner head or cross-bar 76, installation and removal of the outer storm bar 81 is facilitated from the inside of the shade assembly with the shade raised and the lower elevation of the crossbar 82 enabling free access to the attachment bracket 84 under the raised pull bar 37' of the shade assembly.

It will be understood that variations and modifications may be effected without departing from the spirit and scope of the novel concepts of this invention.
