Application June 9, 1937, Serial No. 147,313

3 Claims.

My invention pertains particularly to a folding metal shade which is to be attached to the outside of dwellings or other habitable quarters to prevent the suns rays entering such quarters through windows.

An object of my invention is to provide a window shade which will serve as a storm blind as well as a sun shade, which will be sufficiently weather resistant to permit its use throughout all of the seasons of the year, and which, when not in use, may be folded into a non-obstructive, neat appearing bundle. Other objects of my new invention will be made apparent in the following specification.

My invention will be understood from the following description, taken in connection with the accompanying drawings in which:

Figure 1 illustrates in side elevation the complete shade properly disposed with respect to a window in a wall of a building.

Figure 2 illustrates the complete shade in front elevation.

Figure 3 illustrates a cross-section of the shade taken along the plane 3-3 of Figure 2.

Figure 4 illustrates a cross-section taken along the plane 4-4 of Figure 1, showing the detail of the manner in which the lattice bars and the shades are attached together with bolts.

Figure 5 illustrates a cross-section along the plane 5-5 of Figure 2, and shows a plan view of guide piece 28.

Figure 6 illustrates a cross-section taken along the plane 6-45 of Figure 2 and shows a plan view of guide piece 21 Referring to the drawings, a metal framework, which is made up of guide pipes 8 and 9, a pipe l0 and pipe nipples ll, l2, l3 and I l and Ts l5, l6, ll, I8 and I9, is attached to the wall 2!! of a building by means of lag screws 2|. Metal Washers 22 are disposed between nipples l3, l4 and the wall. Two pantographs 23 and 24 are formed by metal lattice bars and bolts. These pantographs are maintained in position with respect to each other by metal shades 25, which are each attached at their longitudinal extremities to one lattice bar in each of the pantographs. A shade is attached to each of the lattice bars, which slopes downward and away from the wall, while no shades are attached to the last bars which slope upward and away from the wall. Both pantographs are suspended from pipe Hi, the upper lattice bar of each pantograph being pierced by a hole through which pipe ll] extends. A pipe 26, to the extremities of which are attached guide pieces 21 and 28, pierce one of the lattice bars of each of the pantographs. Both guide pieces 21 and 28 are rigidly attached to pipe 26. The guide pieces 21 and 28 are formed from strap iron, bent in a U shape, the sides of the U in each case being pierced by holes through which guide pipes 9 and 8 respectively are disposed. Pulleys 29 and 3| are attached to guide pieces 28 and 21 respectively. A cord 30 is attached to the T l6 and leads thence through pulley 29, thence through pulley 3|, and thence upward and through a pulley 32 to a lug in any convenient location to which the extremity of this cord may be attached.

As illustrated in Figure 4 the lattice bars I) to which no shades are attached, are pierced by a smooth hole through which bolts 33 are loosely fitted. The bolts 33 are threaded through lattice bars a and pierce the flanged edge of shades 25, this flanged edge being held in place against lattice bar a by means of the nuts threaded on bolts The guide piece 28 is equipped with slotted holes through which the guide pipe 8 is disposed, which permits longitudinal movement of pipe 26 with respect to guide pipe 8, while the guide piece 21 is equipped with around hole through which guide pipe 9 is disposed and in which guide pipe 9 fits neatly.

By means of pulling on the extremity of cord 3B, the pantographs, together with the shades, may be raised to any desired position, limited by a position in a compact bundle at the top of the window, in which position they may be held by means of attaching the cord to the lug. Releasing the cord will permit the pantographs, together with the shades, to descend by reason of their own weight, to any desired position.

While I have described in detail one form in which my new invention may be incorporated, it is understood that I do not intend to limit myself to these details, rather intend to claim broadly all of the advantages which are inherent in my new invention.

I claim:

1 A window shade comprising a pair of spaced vertical guide rods, a pair of laterally spaced lazytong members pivotally mounted at their upper ends and adapted for vertical extension and retraction between said guide rods, shade members extending across and secured to said lazy-tongs, oppositely disposed yokes secured to said lazytongs at a point below said pivotal means and slidably engaging the respective guide rods, .pulleys carried by said yokes, and an operating cord secured at one end at a fixed point adjacent the shade members extending across said lazy-tongs, means for pivotally connecting adjacent lattice bars of said lazy-tongs and for attaching said shade members, consisting of bolts extending through adjacent lattice bars, the shank of each bolt having a plain portion for freely engaging one lattice bar, and a threaded end for engaging complementary threads in the other lattice bar, said threaded end projecting beyond said last named lattice bar, and means at opposite ends of said shade members embracing the threaded ends of said bolts for securing the respective shade members in place on said lazy-tongs.
