Application June 9, 1937, Serial No. 147,313
3 Claims. (Cl. 156-17 )
My invention pertains particularly to a folding bars of each of the pantographs. Both guide
pieces 21 and 28 are rigidly attached to pipe 26.
metal shade which is to be attached to the out
side of dwellings or other habitable quarters to The guide pieces 21 and 28 are formed from strap
prevent the sun’s rays entering such quarters iron, bent in a U shape, the sides of the U in
each case being pierced by holes through which
5 through windows.
guide pipes 9 and 8 respectively are disposed.
An object of my invention is to provide a win
dow 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-obstruc
tive, neat appearing bundle.
Other objects of
‘ my new invention will be made apparent in the
following speci?cation.
My invention will be understood from the fol
lowing description, taken in connection with the
accompanying drawings in which:
Figure 1 illustrates in side elevation the com
plete shade properly disposed with respect to a
20 window in a wall of a building.
Figure 2 illustrates the complete shade in front
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 frame
work, which is made up of guide pipes 8 and 9, a
pipe l0 and pipe nipples ll, l2, l3 and Ill and T’s
l5, l6, ll, I8 and I9, is attached to the wall 2!! of
a building by means of lag screws 2|.
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 re
spect to each other by metal shades 25, which
45 are each attached at their longitudinal extremi
ties 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
55 guide pieces 21 and 28, pierce one of the lattice
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 10
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
?tted. The bolts 33 are threaded through lattice
bars a and pierce the flanged edge of shades 25,
this ?anged edge being held in place against lat
tice bar a by means of the nuts threaded on bolts 20
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 ?ts
- neatly.
By means of pulling on the extremity of cord ,
3B, the pantographs, together with the shades, 30
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. Re
leasing the cord will permit the pantographs, to 35
gether 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 4.0
to these details, rather intend to claim broadly all
of the advantages which are inherent in my new
I claim:
1,. A window shade comprising a pair of spaced 45
vertical guide rods, a pair of laterally spaced lazy
tong members pivotally mounted at their upper
ends and adapted for vertical extension and re
traction between said guide rods, shade members
extending across and secured to said lazy-tongs, 50
oppositely disposed yokes secured to said lazy
tongs at a point below said pivotal means and
slidably engaging the respective guide rods, .pul
leys carried by said yokes, and an operating cord
secured at one end at a ?xed point adjacent the 55
upper ends of said lazy-tongs and running over
said pulleys, for adjusting the position of said
2. In a window shade comprising a pair of lat
erally spaced lazy-tongs adapted for vertical ex
tension and retraction adjacent a Window, shade
members extending across said lazy-tongs and
terminating in right angular projections at their
opposite ends, said angular projections being se
10 cured by the pivotal connections of adjacent lat
tice bars of the respective lazy-tongs.
3. In a Window shade of the type comprising a
pair of spaced lazy-tongs adapted for extension
and retraction adjacent a Window and having
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.
