-Improved Safety Tassel of the Pulling Cords Field of the Invention This invention relates to an improved safety tassel of the pulling cords used in the window coverings including venetian blind and the like, partic~ rly to the safety tassel suitable for either two or four pulling cords in a set.
Background of the Invention Conventionally, in a tassel 1 of the pulling cords 2 for a venetian blind? as referred to Fig.l, the ends of both cords 2 are knotted together so as to make the cords 2 Ullr.~ ;Ivably retained by the tassel 1. Accidentally, little boy or girl may be strangled when his or her neck is pressed down between two cords 2 in playing for fun.
In order to prevent the children from accidental str~ng]ing, a window covering cord pull safety device is provided in U.S. Patent 4,909,298 wherein the safety device consists of two members retained by respective cord and detachably coupled together. This device is not taught to be used for the set of four pull cords.
Further, U.S. Patent application No. 08/302,306 filed on Sept.
8, 1994 and assigned to the same assignee of this application discloses a safety tassel of the pulling cords comprising fixed ~ng~g;ng means and removable eng~ing means, the latter ones have respective enlarged opening at radially divergent end only for the relevant cord to be Le~..oved when accidental occasion is arisen. It is found that this safety tassel is well effective for the set of two cords but not so sure for the set of four cords if the cords are somewhat entangled to each other.
Summary of the Invention It is, therefore, the primary object of the present invention to provide an improved safety tassel of the pulling cords, effective for either two or four cords in a set, when any little child is pressed down neck between or among the cords, said cords will be -automatically and effectively released to prevent the child from strangling even the cords are somewhat randomly entangled.
This object is accomplished according to the invention with an improved safety tassel of the pulling cords comprising a body provided with four cord-engaging means, in which at least three are formed with respective radially extended slot having enlarged openings at both divergent and co~veL~e-lt ends.
The aforementioned and other objects, features and advantages will be understood by the following detailed description in connection with the accompanying drawings in which like reference symbols designate like parts thoroughout the figures.
Brief Description of the Drawings Fig.l is a schematic elevational cross section view of the conventional tassel of the pulling cords used in a venetian blind;
Fig.2 is a perspective view of the safety tassel according to the first embodiment of the present invention;
Fig.3 is a cross section view of the first embodiment with the cords engaged therein;
Fig.4 is similar to Fig.2 provided that one of the cords is pulled off;
Fig.5 is a perspective view of the safety tassel according to the second embodiment of the present invention;
Fig.6 is a cross section view of the second embodiment;
Fig.7 is a perspective view of the safety tassel according to the third embodiment; and Fig.8 is a cross section view of the third embodiment.
Detailed Description of the Preferred Embodiments Now, the reference is made to Figs. 2 to 4 which illustrate the safety tassel of the pulling cords according to the first embodiment of the present invention. The present tassel has a hollow body 1 in a configuration of inverted cup for illustrative purpose but not for limitation. The body 1 is, for example, closed at upper side and opened at bottom side. Of course, said bottom can be alternatively 2138~7~
.
closed too. A central recess 11 is formed on the top to have a circular ridge 12 raised in relation to said recess 11 along the periphery, and a corresponding ~nmll~r dome under said ridge 12 is formed circumferentially inside of the body 1. So long as said dome is formed internally it is not necessary to have the recess 11 at external surface. In other words, it may be thickened, for example, at top central portion of said body lto the extent in forming a flat surface.
As cord- engaging means four slots 13 are formed radially extending, in the directions orthogonal to each other, namely angularly spaced apart in equidistant to each other between slots 13, over said ridge 12 and thus the corresponding dome. At both convergent and divergent ends of each slot 13 out of the location of said ridge 12 are formed with enlarged openings 14 and 15. The opening 14 at convergent end of each slot 13 is terminated at the center, so that all openings 14 of four slots 13 are identical to each other and, in effect, becoming one common opening 14. Namely, the only one opening 14 is simultaneously served as convergent end openings for all four slots 13.
Two or four pulling cords 2 (two are shown in this embodiment) in a set are passed through respective slot 13 and knotted at the end 21 thereunder. The size of the knotted end 21 is of course greater than the transverse width of said slot 13 so that being positively retained inside of the body 1, but is smaller than the diameters of either convergent end or divergent end openings 14 and 15, respectively, which are substantially in same sizes. The width of each slot 13 is preferably about the same size as the cross section of said cord 2 or even a slightly smaller to restrict the cord arbitrarily displaced within the slot 13.
Since the distance between any two slots 13 is much less than the normal size of any human neck, so that if child press the neck between any two or among more than two of the cords 2, said cords 2 are enforcedly displaced under the action of said neck twowards the divergent end openings 15 and pulled off automatically. Even if any or some of cords 2, most possibly the diametrically opposite cords 2, would be somewhat entangled in abnormal state, thus said entangled cords 2 would be probably not displaced towards the divergent ends of said slots 13 rather in the opposite direction toward the col~ver~ent ends of said slots 13, then the cords 2 under this circumstance are readily displaced until the convergent end opening 14 and also pulled off unobstructedly. Therefore, in any accidental case, the cords 2 are assuredly released or detached from the body 1 to prevent themselves from causing probable strangling to the child.
The opPnin~.~ 14 at coll~er~ellt ends of said slots 13 can be in~eppndently as referred to the second embodiment illustrated in Figs. 5 and 6. The action and effect are substantially the same as mentioned above in conjunction with the first embodiment shown in Figs. 2 to 4.
Further, a third embodiment is illustrated in Fig.7 and 8. In comparison with the second embodiment, it is seen that one of the four cord-engaging means, i.e. the slots 13, is replaced by a central hole 16, and other three slots 3 are angularly spaced apart in eqni~istant. In this embodiment the cord 2 that is passed through said hole 16 and knotted at 21 thereunder would be still retained and not released when the aforementioned accident is hap~ened. Since other three cords 2 that passing through said three slots will be detached just the same as described with reference to aforementioned first and second embodimentsso that only one cord 2 remained and retained in the body 1 cannot cause any harm to the child.
While there have been shown and described what are presently considered as preferred embodiments of the invention, it will be obvious to those skilled in the art that a number of changes and variations may be made without departing from the scope of this invention as defined by the appended claims.
