BACKG~OUND OF THE INVENTION

Field of the Invention The present invention relates to assemblies comprising ` a flexible screen or sheet removably mounted to a support structur~
by fastenexs which engage opposite edges of the screen and place the screen in tension therebetween, said screen being relatively non-elongatable under the range of tensions applied by said fasteners and, in particular, relates to assemblies comprising relati~ely flexible sheet of screen material, or screen, removably mounted over a window opening in a support structure and one-piece spring steel fa~teners therefor.

Description of_the Prior Art ..
Screens or sheets utilizea to cover window openings and the liXe to provide protection from the rays of the sun~ or to lS prevent antry of insects and the like, are well known in the prior art. ~n the past, such screens or sheets were usually mounted in frames and then the frames attached to the structure at the window opening, or the screens or sheets were attached directly to the structure by means of adhesive or tacks or the like. The prior art mounting techniques are not completely satisfactory as frames are relatively expensive to manufacture, require storage, and are usually only available for standard openings or require c~stom ~; assembly. Also, the assembly of screens or sheets directly to the structure often results in damage to the structure and/or screens and often provides a difficult and time consuming assembly operation. Alsol i~ sun screens are utilized in combination with conventional wire mesh screens o~ the type designed to prevent the entry of insects, the two screens are often mounted on opposite sides of the window frames. In such situations, the prior art screen or sheet mounting techniques are usually not satisfactory.

,. . ,, -1, ... ~'''.

According to the present invention there is pI ~D ~d a one piece sheet metal fastener including a g~ ~ lly cross-sectional "D" shaped body, the body including a ~ -ally flat base portion having an aperture therethrough ad ~ I to receive the shank of an externally threaded mem~er. The body fur-ther has a generally flat face portion extending generally perpendicularly to the base portion, the face portion and the base portion each having a Eree end, the free end of the face portion being adjacent the free end oE the base portion. The body further has a generally arcua~e portion e~tending from the end of the base portion remote from the face portion to the end of the face portion remote from the base portion, the arcuate portion having an opening thereJ-hrough generally aligned with the said aperture in the base portion, the face portion having at least one projection extending outwardly from a point remote from the free end of the ! face portion and then generally parallel to the face portion toward the free end of the face portion.
In accordance with the present invention, many of the drawbacks of the prior art have been eliminated or minimized by the use of an assembly, for example, which comprises a relatively flexible screen and a plurality of one-piece sheet metal fasteners for use in quickly and inexpensively mounting the screens to a support structure such as a window frame or the like. The screen or sheet includes two opposed edges, preferably the horizontally extending top and bottom edges, which are designed to be retained by the fasteners under tension. The edges are preferably metallic and/or plastic extrusions which are permanently attachable to the sheet or screen material after such material has been cut to satisfactory length.

tm/ ~ -2--., .
~ 3 ;~ The material i5 substantially non-elongatable under the '`~, range of tensions applied thereto by the fasteners. The one-piece, resiliently deformable, sheet metal fasteners may be formed as by a stamping and define the generally , D-shape in cross section.
~ .
In operation, at least one fastener is attached to the support structure at at least bwospaced locations, preferably at opposite ends of a ~indow opening or the like.
One edge of the flexible material is engaged with the tangs of the at least one fastener at one end of the window ope~ng and then said fastener is resiliently deformed as the other edge of the screen is engaged with the tangs of the at least one fastener at the other end of the window opening. The non-deformed separation between the tangs of the fasteners at the opposite ends of the window , opening is somewhat greater than the spacing between the portions of the edges of the screen designed to engage the tangs and thus the fasteners will be resiliently -~ deformed to engage the screen under a tension. The range of tension under which the screen is placed by resilient deformation of the fasteners is insufficient to, elongate the sheet. One or both edges of the sheet may be further attached to`the fasteners by means of a threaded member : - . .
which will pass through an aperture provided in the edge of the screen and will be engaged in a thread impression provided in the fastener. The sheet may be removed from the support structure by simply deforming the fasteners suffic;ently to disengage one of the edges of the screen from the tangs of the at least one fastener at either end of the window opening.
It is an object of the present invention to provide a one piece~ resiliently'deformable sheet metal fastener tm/,'','-' 7~i for removably mounting a relatively flexible sheet or screen to a support member.
These an,d other objects and advantages of the present invention will become apparent from a reading of the ~' detailed description of the preferred embodiment taken in connection WLth the accompanying drawings.

FIG. 4 is a front ~iew of the fastener of FIG. 2, as viewed from line 4--4 in FIG. 3.
FIG. 5 is a top view of the fastener of E'IG. 2, as viewed from line S-~5 in FIG. 3.
FIG. 6 is a bottom view of the fastener of FIG. 2, as vie~ed from line 6--6 in FIG. 3.
' 20 ' FIG. 7 is a perspec-tive view of an alternate embodiment of the fastener of the present invention. ' FIG. 8 is a fragmentary cross sectional view of an assembly utilizing the fastener of FIG. 7.
The assembly A and fastener 10 of the present invention may be seen by reference to FIG. 1. In FIG. 1, a generally flexible screen or sheet 12 is removably mounted to a support structure S, preferably over a window opening therein, by means of at least two fasteners 10. The support structure S is illustrated as including a window frame F to wh-ch the s~eet 12 is remo~ably mounted by a plurality of fasteners 10 which engage op~osed ~dges 14 and 16 of the screen 12. The distance betw~en t~e poxtion of the edges 14 and 16 which aXe en~a~ed by the fasteners 10 is tm/ i ': ~ ' ' . ., ` . :

' slightly less than the distance between that portion of the fasteners 10 in the non-deformed position thereof which engage the edges 14 and 16 and thus the fasteners 10 are resiliently deformed when engaging both of the edges 14 and 16 placing the screen 12 in tension. The screen 12 i5 substantially non-elongatable in the range of tension applied thereto by fasteners 10. Fasteners lO are preferably identical as are edges 14 and 16 of sheet 12. Fasteners lO are attached to the frame F as by screws 18 or any other conventional attachment means.

; lO Edges 14 and 16 are located on opposed edges of screen 12 r preferably the horizontally extending top and bottom edges of the sheet and may comprise continuous relatively rigid forms, prefexably extrusions or the like. In ~he preerred form the edges 14 and 16 have means, such as fingers 20, for engaging the fasteners 10, means 22 for attachment to the flexible screen material, spacer means 24 to engage the fastener lO or the structure S to retain the screen 12 generally parallel to the plane of the window and an aperture 26 to allow passage of the shank of a threaded fastener such as a screw.
.
As may be seen by reference to FIG. l, at one or more of the edges, 16 or 14, threaded members such as screws 28 may be utilized to attach the edges of the screen to the fastener lO, or the fingers 20 of the screen edges may be retained by the fasteners entirely by tension applied thereto as a result of the resilient deformation of the fasteners lO.
.
; The structural features of fastener lO may be seen in greater detail by reference ~o FIGS. 2 through 6. The fastener lO
is a one-piece sheet metal stamping having a generally "D" shaped ; cross section as may be seen by reference to FIG. 3. The fastener , 30 is formed of a spring steel or other sufficiently resilient metal.

Fastener 10 comprises a base portion 30, a face portion 32 extending generally perpendicular to the base portion, and an arcuate portion 34 extending from the end 36 of the base portion remote from the face portion 32 to the end 38 of the face portion 32 remote from the base portion 30. The free end 40 of the base portion 30 is generally adjacent the free end 42 of the face portion 32 in the non-deformed position of ~he fastener 10.

The base portion 30 of fastener 10 may include an aperture or slot 44 for receip~ of the shank of a mounting screw 10 ~ 18 and the arcuate portion 34 may include an enlarged slot or opening 46 generally alig~ed with slot 44 to allow passage of a tool such as a screw driver or the like.
..' The face portion 32 of fastener 10 includes at least one, and preferably two, tangs 50 extending outwardly from the face portion and towards the free end 42 thereof. The tangs are ~ adapted to engage fingers 20 of the screen edges 14 and 16. The - face portion 32 may also include a thread impression 52 as is well known in the art.

An alternate embodiment of the present invention may be seen by reference to FIGS. 7 and 8.

In the alternate embodiment, fastener 110 has a generally D-shaped cross section similar to fastener 10 described in detail above. Fastenex 110 includes a base portion 130, a face portion 132, and an arcuate portion 134 extending between the end ; ; 25 of the base portion remote from the face portion to the end of the face portion remote from the base portion. The face portion includes tangs 150 and a thread impression 152 functionally identical to tang 50 and thread impression 52 described above.
The base portion includes a slot 144 for receipt of the shank of a mounting screw 18.

. 77-TNR-210 ;` ' The fastener 110 difers from fastener 10 in that it includes a leg portion 160 extending from the end of the base ~ portion 130 closest the face portion 132 and generally parallel .~ with the face portion. The leg portion ].60 includes an aperture 162 or the like for mounting the fastener 110 to a window frame F with a mounting screw 118 without requiriny access to the back end of fastener 119. Thus, either slo~ 144 in the base portion .
or aperture 162 in leg portion 160 may receive mounting screw 18 or 118, respectivelyO

Although this invention has been described in its preferred forms with a certain degree of particularity, it i5 understood that the description of the preferred forms has been . ~ made only by way of example and many modifications and changes in; the details of construction and arrangement of the parts may bs ; i5 resorted to without departing from the scope of the invention as hereinafter cl me~.
