The present invention relates generally to overhead shelters, and more particularly to a novel canopy incorporating a flexible covering supported by adjustable brackets adapted for demountable attachment to a substantially vertical wall.

It is an object of the invention to provide a novel canopy construction which lends itself readily to the fabrication of canopies of various sizes and shapes from available stock.

It is another object of the invention to provide a novel canopy construction which incorporates means for adjustably tensioning a flexible covering.

lt is another object of the invention to provide a novel canopy bracket construction which incorporates standard parts assembled in a selected arrangement to provide a desired shape of canopy.

It is another object of the invention to provide novel means including an extruded mounting strip for demountably attaching a canopy to a substantially vertical wall.

The foregoing, along with additional objects and advantages, will be apparent from the following description of a preferred embodiment of the invention as illustrated in the accompanying drawings, in which:

In its depicted embodiment, the canopy, designated generally by the reference numeral 2i), comprises a flexible covering 22 supported by a frame 24. A mounting strip 26 and a plurality of mounting plates 28 are provided for attaching the frame 24 to a vertical wall, the mounting strip 26 being further adapted to retain one edge of the covering 22, as will appear.

The flexible covering 22 is made up of a series of slats 2,949,649 Patented Aug. 23, 1960 `ice Z 30, preferably of metal, the edges of which are oppositely rolled and the middle portions of which are given a somewhat reversed` curve. Thus formed, the slats 30 engage in a swivelling manner which is readily discernibleV from the illustrations of Figures 3 and 5. These rolled interlocks are such as to prevent disengagement of adjacent slats, but to permit a free articulation which will enable the covering 22 to adapt itself to various contours according to the particular shape of an underlying support'. A flexible covering of the foregoing type is fully disclosed in an application of Harry Nelson bearing Serial No. 561,900, led January 27, 1956, now Patent No. 2,894,- 572, issued July 14', 1959.

As is clear from Figures 1 and 2, the frame 24 of the canopy 20 includes an elongated cylinder 32 supported at spaced points by means of brackets 34, each bracket 34 comprising an upper bracket arm 36 and a lower bracket arm 38 joined together by means of an angle clip 40. This joint is illustrated in section in Figure 5, and it will be observed that bolt assemblies 42, which serve to secure the angle clip 40 to the

arms

36 and 38, serve also to secure upper and

lower support clips

44 and 46 to the respective arms 36 and 33. The portions of the

clips

40, 44, and 46 which embrace the

arms

36 and 38 are preferably curved to iit the latter as illustrated in the cross sectional view of Figure 6. Figure 9 shows a removed support clip 46 and illustrates the manner in which a free end portion 48 is formed to iit around the cylinder 32. It will be understood, of course, that the support clip 44 is similar to the clip 46, but has a somewhat shortened free arcuate portion so that, when the two

clips

44 and 46 are assembled in the manner of Figure 5, there will be a substantial gap between their free ends.

The cylinder 32 can be formed of sheet metal, one edge of the sheet being formed to a groove 50 that extends the full length of the cylinder. The edge of the metal forming the groove 50 is then brought outwardly at something of an angle to a radius of the cylinder, and the opposite edge of the sheet forming the cylinder is crimped over it as illustrated in Figure 5. This construction provides the groove 50 with a rigid lip 52 which projects angularly across the opening of the groove. The ends of the cylinder 32 are provided with any type of suitable end cap S4.

The upper bracket arm 36 of the bracket 34 is preferably bent to an arcuate shape so as to provide a continuous slope from its secured end down to the end adjacent the cylinder 32. The exact shape, however, can be varied Widely to suit the convenience of individual installations and to provide an aesthetic appearance. The lower bracket arm 38, while preferably straight, may take Various bent forms as will be apparent. The

arms

36 and 38 may be of metal tubing, either searned or seamless. If desired, an ornamental brace such as that shown in broken lines and designated S5 in Figure 1 may be formed from strip stock and mounted between the

arms

36 and 38 by means of sheet metal screws or the like.

The ends of the upper and lower bracket 36 and 3S to be secured against a vertical wall are provided with bracket clips 56, one of which is shown removed in Figure 8. These bracket clips 56 are employed in pairs to embrace the

tubular arm

36 or 38, as the case may be, as clearly shown in the cross sectional view of Figure 7. Figures 3, 4 and 8 show the semicircular portionof the clip 56 to be provided with a plurality of spaced holes 58 by means of which the clips may be secured to the bracket arms in an adjusted position and retained by means of bolt assemblies 64B. Each of the clips 56 has a free end which is bent to hook form as clearly illustrated in Figures 3, 4, 7 and 8. These hooks are designated by the numeral 62 in the drawings.

The mounting strip 26, shown in isometric View in Figure 10, is preferably formed as an extrusion, but may be otherwise shaped or molded if desired. It compreses a back plate 63 provided with spaced holes 64. The lower edge of the back plate 63 is provided with a ange-like extension 66 which projects forwardiy and downwardly therefrom, as clearly illustrated in Figures 3 and 10 of the drawings. At its upper edge, the back plate 62 is provided with an arcuate extension which curves forwardly and then downwardly to provide an upper arcuate ange 68 which forms an inside recess or groove 70. Intermediate the

flanges

66 and 68 aforementioned, an intermediate flange 72 is provided. This latter flange has an upward curve which approaches, but does not meet the free edge of the flange 68. It will be observed, incidentally, that the free edge of the intermediate flange 72 projects somewhat farther forwardly of the back plate 62 than does the free edge of the lower flange 66.

The mounting plates 28, one being shown removed in Figures ll and l2, each includes a back plate 74 which may have beaded longitudinal edges 76 for added strength and rigidity and'which has slots 78 provided for mounting the plate against a wall surface. intermediate these mounting slots 78, the back plate 74 has opposed flanges 80 pressed or otherwise extended therefrom as illustrated in Figures 4, ll and 12.

The manner of erecting the canopy 20 is generally clear from the drawings. The upper and

lower bracket arms

36 and 38 are joined together in pairs, along with an angle clip 40 and

support clips

44 and 46. The

clips

44 and 46 cooperate to support the cylinder 32 which is disposed with the groove 50 in the approximate position illustrated best in Figure 5. This enables the hooked edge of the end slat 30 of the flexible cover 22 to be hooked over the lip 52 for retention. The opposite ends of the

bracket arms

36 and 38 carry the mounting clips 56 which engage the appropriate anges of the mounting strip 26 and mounting plates 28, the strip 26 and plates 28 being, of course, secured to a vertical surface, designated in the drawings by the window frame 28, by means of screws 84. y

The free rolled edge of the uppermost slat 30 of the flexible covering 22 is disposed within the recess 70 formed by the upper flange 68 of the mounting strip 26, this engagement being clearly illustrated in Figure 3. It is, of course, obvious that this engagement may be easily effected by sliding the rolled edge of the slat 30 longitudinally with respect to the recess 70, and it may be preferred to engage this upper end of the covering 22 before hooking the lower end to the cylinder 32 as aforementioned. With both ends of the covering 22 retained as described, the bracket frame 34 should be adjusted outwardly with respect to the mounting clips 56 so as to provide an appropriate tensioning of the flexible covering 22 to prevent its fluttering or rattling due to wind gusts and the like. It will be noted that the construction of the covering 22 is such as to provide resiliency which enhances the effectiveness of the tensioning process. With the covering 22 appropriately tensioned, the bolt assemblies 6.0 are placed through appropriate holes 53 in the tension clips 56 to retain the rigid assembly.

It will be observed from a comparison of Figures 3 and 4 that the upper bracket arm 36 is disposed at a slight inclination to the horizontal due to the greater forward projection of the intermediate flange 72 of the mounting strip 26 as compared to the lower flange 66. This insures that the upper end of the covering 22 will likewise be disposed at a slight inclination which will prevent the accumulation of rain puddles, dirt, etc.

Clearly, there has been provided a canopy which fulfills the objects and advantages sought therefor.

It is to be understood that the foregoing description and the accompanying drawings have been given by way of illustration and example. It is further to be understood that changes in the form of the elements, rearrangement of the parts, and substitution of equivalent elements, all of which will be apparent to those skilled in the art, are contemplated as being within the scope of the invention, which is limited only by the claims which follow.
