VENETIAN BLIND CORD PULL Filed June 24, 1946 4+- fiw gadmwdmw Elm.
INVENTOR.
ner applied to the other cord I5, except that the arrow points upwardly by introducing the cord through the head-end of aperture 23 and tying it similarly causing its knot to occupy hole 2 i as depicted in'Figures 1 and 2.
Thus the operator knows at a glance which arrow to pull to tilt or slope the blades or slats transversely either inwardly downwardly or inwardly upwardly, and the pulls are of such size and shape that their actuation is a matter of ease and convenience rather than one of conjecture as was common occurrence prior to the production of this innovatory structure which is especially inexpensive to produce because both arrows are alike, although differently applied to their respective cords.
In Figures 6 and '7 is shown a modified and, at least in some cases, a preferred form of pull which, as indicated hereinbefore, is to be applied to the cord pointing either upwardly or downwardly, the latter condition only being depicted in the drawing since the reverse application will be readily understood. 1
Insofar as convenient, the reference numerals used in these Figures 6 and '7 are the same as those employed in the other figures plus 100.
' In this case, instead of having a round hole 2 2 through the pull intersecting the aperture i223 which extends longitudinally centrally through the whole length of the pull, the arrowhead, characterized as a whole H3, is divided transversely into two parts, the main body designated WI and the tip portion identified as I32, the former having a central cylindrical cavity I33, constituting in effect an aligned enlargement of the aperture I23 and near its mouth having a very shallow, circular internal groove I34.
The apertured arrow-tip member I32 has a tapered external surface conforming to and constituting an extension of the outer surface of member ISI, such part I32 having a short cylindrical extension designed and adapted to fit snugly in the mouth of the cavity I33 and supplied with a shallow circular rib adapted to be forced into groove ISd and thereby firmly hold the member I32 in place and against removal after the complementary parts I3I and I32 have been applied together in the relation illustrated.
In buying the two pulls for the two cords,
the purchaser receives two like members Iii and two like tips I32 wholly separate from the parts I3I.
He then applies one of the elements I3I to the end of one cord by feeding it through aperture I23 and into cavity I33. Then he ties the knot I25 in the end of the cord whereupon he pulls the cord back thereby retracting the cord into the cavity, and then he applies the tip member I32 to such part I3! upon completion of which action the knot is wholly concealed and the tip retained in place due to the interfitting of its rib into its accommodating groove I34.
Thus the application of the downwardly-aimed arrow is finished.
To fasten the other pull to the other cord, the latter is fed through the aperture I23 of the remaining tip I32 and the knot tied in its end whereupon the tip is applied to the member I3I with the knot in the cavity I33, thus completing the fastening of such upwardly-aimed arrow pull to the cord, or it may be considered that the member I3I is applied to the knotted cord tip.
. The structure presented in Figures 6 and 7 has the advantage that after the pulls have been applied to the cords the knots of the latter are not visible.
Those acquainted with this art will readily understand that the invention as defined here inafter is not necessarily limited and restricted to the precise and exact details set forth hereinbefore and in the drawing, and that reasonable modifications may be availed of without departure from the heart and essence of the invention and without the loss of any of its material benefits and advantages.
I I claim:
1. A pull for a Venetian-blind hanging cord controlling the transverse slope of the slats of the blind to be manipulated by the cord, said pull having the general form of a tapered directionindicating arrow-head equipped with a longitudinal central stem, said arrow-head having an externally accessible cavity, the pull having a longitudinal passage extended through said head and. stem and intersecting said cavity and of a caliber to receive the lower terminal portion of said cord, whereby said portion of the cord may be inserted in the pull passage through either end of said passage into said cavity, its then accessible end knotted, and said knot occupying said cavity and supporting the pull on the cord.
2. A pull for a Venetian-blind hanging cord controlling the transverse slope of the slats of the blind to be manipulated by the cord, said pull having, the general form of a tapered directionindicating arrow-head equipped with a longitudinal central stem, said head having a hole therethrough from its front to its back and open at both ends, the pull having a longitudinal middle passage extended through said head and stem I and intersecting said hole and of a caliber to receive the lower terminal portion of said cord, whereby said portion of the cord may be inserted through either end of said passage into said hole, its then accessible end knotted and the knot occupying said hole and supporting the pull on the cord.
3. A pull for a Venetian-blind hanging cord controlling the transverse slope of the slats of theblind to be manipulated by the cord, said pull having the general form of a relatively large flat tapered direction-indicating arrow-head equipped with a comparatively small, central longitudinal stem, said head having an externally accessible cavity, the pull having a longitudinal middle passage extended through said head and stem and intersecting said cavity and of a caliber to receive the lower terminal portion of the cord, whereby such portion of the cord may be inserted in the pull through either end of said passage aperture into said cavity, its then accessible end knotted, with the knot occupying said cavity and supporting the ull on the cord.
4. On a Venetian-blind having a pair of hanging cords to control by downward pulls thereon the opposite transverse tilts of the blind slats,
a pair of like cord pulls with one applied to each cord, each such pull having the general form of a tapered direction-indicating arrow-head equipped with a longitudinal central stem, each,
said head having a hole therethrough from its front to its back and open at both ends, each said pull having a longitudinal middle passage extended through the head and stem and intersecting said hole and of a caliber to receive the lower terminal portion of one of the cords extending in the pull through either end of said passage'into said hole, its end in said hole having'b'een knotted with the knot supportingthe pull on its cord, one of said pulls being on its cord aiming downwardly and the other pull on its cord aiming upwardly to indicate the direction of slope of the slats of the Venetian-blind, depending upon which cord is pulled down.
5. A pair of like Venetian-blind cord pulls adapted to be applied to the terminal portions of two such cords in reverse directions, each such pull having the general form of a direction-indicating tapered arrow-head equipped with a central longitudinal stem, said head having a cavity adapted to accommodate a knot of its cord and said head and stem having a longitudinal aperture open at both ends and intersecting said cavity, the cord entering such cavity in one case through the head aperture and in the other case through the stem aperture.
n 6. The cord pulls set forth in claim 5, in which each said head is divided into two parts on a transverse plane intersecting said cavity, said two parts being interfittable in a manner to prevent their separation upon actuation of the cord. by the pull.
