5 Claims.
This invention relates to Venetian blinds and particularly to the slat-tilting mechanism thereof. The present application constitutes a division of my copending application Serial No. 52,725, filed December 3, 1935.
The slat-tiltingmechanism of Venetian blinds in many instances includes an operating wheel which when turned in one direction tilts the slats one Way and when turned in the opposite direction reverses the tilting of the slats.
In some instances the tilting wheels are grooved sheaves about which a tilting rope passes. This construction is satisfactory from the point of quiet operation, but is unsatisfactory in many instances because of relative slippage between the rope and the sheave.
In other instances the tilting wheel is in the form of a sheave having pockets in the groove of the sheave which receive individual balls of a ball or bead chain which takes the place of the rope. This arrangement is satisfactory from the point of efficient operation but unsatisfactory from the point of noise resulting from the hanging ends of the chain clattering against the window-frame in a breeze and also from the point that bead chain is relatively expensive as compared to rope or cord.
The object of the present invention is to combine the desirable features of the chain and rope in a single operating element While at the same time eliminating the undesirable characteristics of each.
This object is primarily attained by providing a neat-appearing efficient and inexpensive connecter for the chain and the rope which will be fully disclosed hereinafter, reference being had to the accompanying drawing, of which:
Fig. 1 is a side elevation of the means for attaching the pull cords of the tilting mechanism to the sheave chain thereof, in the process of connecting one to the other;
Fig. 2 is a longitudinal sectional elevation of the mechanism shown in Fig. 1, with the attaching means in its ultimate position;
Fig. 3 is a side elevation of the mechanism shown in Figs. 1 and 2; and
Fig. 4 is a cross section taken on the line 44, Fig. 3.
In order to detachably connect the pull cords I to the tilting chain 2 a device 3 of the character shown in Figs. 1, 2 and 3 is provided. This device comprises a substantially cylindrical longitudinally split sleeve 4, the opposite edges 55 of the split 6 being serrated or undulated so as to interlock with each other about the upper end of the cord I, as shownin Fig. 3, for frictionally gripping said cord and to prevent raveling of the embraced end thereof.
The side of the sleeve 4 opposite the split 6 is provided with a longitudinally extending neck 1 at the outer-end of which is a semi-spherical hollow head 8. The neck 1 is formed integral with the one side of the body or sleeve 4 and with one side of the head 8. Integrally connected to the diametrically opposite side of the head is a depending arm 9. At the free end of the arm 9 is a hand l0 having laterally projecting fingers or teeth II which, as shown in Fig. 2, are adapted to be pressed into the cord l to prevent the cord from slipping axially of the sleeve or body 4 of the cord-chain connecter 3.
The hand 10 is arranged to be embraced by the upper end of the body sleeve 4 when the same is pinched or closed about the cord I, thus securing the hand in place, as clearly shown in Figs. 3 and 4, and whereby the arm 9 is positioned opposite to the neck I to provide an opening I2 between the upper end of the body sleeve 4 and the lower end of the hollow semi-spherical head 8 for the passage of the end ball or head l3 of the chain. 2, said chain being composed of a series of such balls or beads connected together in spaced relation to each other by a central cord or links M.
In order to make the ball I3 readily detachable and connectible from and with the head 8 said head is slotted radially from the apex thereof to the bottom edge thereof as indicated at M for the reception and passage of the link M which connects the end ball I3 with the next succeeding ball of the chain.
I claim:
1. A one piece connecter comprising a clamping sleeve arranged to embrace and rigidly grip a rope adjacent one end thereof said sleeve having a single longitudinal split extending from end to end of the sleeve, a chain receiving head on and formed integral with one end of the sleeve, and a projection integral with said sleeve and arranged to project into the rope transversely thereof to prevent relative axial movement between the rope and the sleeve.
2. A one piece connecter comprising a clamping sleeve arranged to embrace and rigidly grip a rope adjacent one end thereof said sleeve having a single longitudinal split extending from end to end of the sleeve, a chain receiving head on and formed integral with one end of the sleeve, and a projection integral with and extending beyond said sleeve at one end thereof and arranged to project into said end of the sleeve and pene-
