PATENT ori-lcs amm . wnmow amm mum a. sa, vlniu, ou. Application october es. ma, serial No. esiste s einen.' (ci. iss- 11) This invention relates to window blinds and has for an object to' provide 'a device of this character which may be easily applied to window frames outside the sash for preventing ingress of insects into the building and at the sametime deilectingvthe suns rays from shining into the building so that insulation against the sun's heat through windows will be greatly promoted.
A further object is to provide a device of this l character which will be formed of a few strong simple and durable which may be inexpensively manufactured and which will not easily get out of order.
With the above and other objects in view the l invention consists of certain novel details of construction'and combinations of Darts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacriiicing any4 of the advantages of the invention.
In the accompanying drawing forming part of this specification,
. blind.
v ofthe arrowheads.
Figure 4 is a detail cross sectional view-showing the manner of tying the tapes to theslats. Referring now to the drawing in which like characters of reference designate similar parts in the various views, designates the frame and Il the wire mesh screen of s conventional window screen which may be attached to the outside of the window frame or may be applied tothe win dow frame underneath an upper sash as is eustomary in the use of window screens.
` In carrying out the invention the window screen imtldescribed is provided, as a unitary structure therewith, with a plurality of llporllosed slats Il formed of any desired material .and suspended in a predetermined angular position irom the top cross member I3 of the frame IO through the medium oi' spaced tapes Il which are looped over respective end portions of theslats in the same manner as in the construction of venetian'blinds. and aresecuredto thesiatsthroughthemediumof ioopedthreads il,therebelngapairofthese threadsengagedaroundeachslatandpassed through ,the front and rear reaches of the respective tape, the indivldualthreads intersecting Figure l is a front elevation of the window a slat blind comprising a respectiveplate i6 which is secured to the top cross member I3 through the Imedium of nails or other connectors. One reach of eachI tape is of greater length than the other reach so that the angular inclination of the slats to the horizontal is permanent. The degree of slant is determined by the amount of each reach engaged aroundthe respective plate it before it is secured in place. vPreferably the slope is such that the suns rays will be deilected so as not to enter the room directly and thus insulation from the suns heat will be greatly promoted.
vertically disposed guide wires I8 are engaged through openings I! disposed near the ends o f the slats, the upper ends of these guide wires being secured to the top cross member I 3 of the frame through-the medium of stapes 20 or other suitable connectors.. The lower ends 'of the wires are trained through openings 2Min the lower-l `most slat and it will be pointed out that these openings are disposed closer together than the openings of the other slats for a purpose to be described.v The extreme lower endsof the guide wires are looped around bolts 22, best shown in Figurez, which are passed upwardly through the bottom cross member 23 of the frame, and thence looped back as shown at 26 to provide a knot,
friction of the 'guide wires upon the walls of theopenings to insure that the lslat blind will remain in any adjusted open position longitudinally of the guide wires.
yl'iortuliustingtheslatblindapairoi'cords 21 are downwardly through openings 28 in the slats and the lower ends knotted as shown at 2! underneath the bottom oi' the lowermost slat. The upper ends of the cords are trained horizontally through guide eyes Il secured to the vtop. cross member Il and from thence trained side by'side to aguide .eye 3| located on one longitudinal -member ofthe trame. thence carried downwardlyand knotted as shown at l! toa second pair of cords 83. A
' The secondpair' of cords 88 are trained downwardly from the knotted upper ends thereof along when the operatorfpulls down upon the cords 27 and 33 the slats will be moved upwardly to adjust the slat blind to any degree of closed position. Conversely when the operator pulls upwardly on the cords 21 and 33 the slats will be moved downwardly to adjust the slat blind to any degree of open position from top to bottom of the frame I0.
Since the operation of the device has been described as the description of the parts progressed it is thought the invention will be fully understood without further explanation.
What is claimed is:
l. A window blind comprising a frame, a plurality of superposed slanted slats within the frame, limp tapes suspending the slats from the upper transverse member of the frame, said slats having openings near the ends, guide wires secured to the upper and lower transverse members of the frame and engaged through said openings, the openings. of the lowermost slat being closer together than the openings of the other slats so that said guide wires are deformed when passing through the openings of the lowermost slat to create friction for holding the slats in adjusted positions, and cords connected to the slats for moving the slats on the guide wires in the nature of a Venetian blind.
2. A window blind comprising al frame, a plurality of superposed slanted slats withinthe frame, limp tapes suspending the slats from the upper transverse member of the frame, said slats having openings near the ends, guide wires engaged through said openings, the openings of the lowermost slai'l being closer together than the openings of the remaining slats, means for adjustably tensioning the guide wires to create frictional engagement therewith with the walls of/the closely spaced openings of the lowermost ,slat for holding the slats in adjusted open or from the upper transverse member of the frame;
each tape having th rear reach of greater length than the front reach for maintaining a permanent predetermined slant of the slats, said slats having openings near the ends, guide wires engaged through said openings, the openings of the lowermost slat being closer together than the openings of the remaining slats, a bolt and nut connecting the lower end of each respective guide wire to the lower cross member of the frame, adjusting of the nut on the bolt adjustably tensioning the guide wires to create frictional engagement therewith with the walls of the closely spaced openings of the lowermost slat for holding the slats in adjusted open or closed positions, cords ,connected to the lowermost slat and slidably engaged with the remaining slats, guide eyes training the cords transversely across the uppermost slat to one .longitudinal member, said cords being thence trained downwardly on said longitudinal member, cords connected to the lowermost slat, guide eyes training the second named cords along the lowermost member of the frame@- to said longitudinal member and thence upwardly i thereupon, and a knot connecting both setsofv cords together, downward pull upon the knotted cords moving the slats to adjusted closed positions, upward pull upon the knotted cords moving the slats to adjusted open positions.
