1 Claim. (01. 24115) This invention relates generally to sliders for assembly cords or the like, and has particular reference to a slider adapted for assembly onto the ends of a drawstring of a garment or the like.

The object of the invention is to provide a slider having separable parts, each of which is adapted to slidably receive one end of a drawstring or the like.

Another object of the invention is to provide a slider having separate cord-engaging portions which are adapted for snapping engagement with each other.

A still further object of the invention is to provide a slider having a pair of elongated cordengaging members formed of a flexible rubberlike material, in which cooperating snap fastening means is provided on the ends of the members to enable them to be snapped together.

Other objects of the invention will, in part, be obvious, and will, in part, appear hereinafter.

In the drawing:

Fig. 1 is a plan view of the component parts of a slider embodying the features of the invention;

Fig. 2 is a view in side elevation of the slider parts shown in Fig. 1;

Fig. 3 is a plan view of the assembled slider which has been mounted on the ends of a drawstring cord or the like;

Fig. 4 is a view of the assembly of Fig. 3 as seen from the left end;

Fig. 5 is a view of the assembly of Fig. 3 as seen from the top; and

Fig. 6 is an enlarged view in section taken on line 6--6 of Fig. 3.

Referring to the drawing, there is illustrated a slider assembly 10 which is particularly adapted for assembly onto the ends I2 of a loop of drawstring cord M for use on the hood or other portion of a garment such as a snowsuit or the like (not shown).

The slider-comprises generally two cooperating cord-engaging members l6 and I8 which in the preferred embodiment are formed from a tube of flexible or rubber-like material. The members are adapted to be superimposed and fastened together during use, and to provide means for such fastening, the member i6 is provided with a pair of snap fastener studs 20 which are assembled onto the ends of the member by attaching members 22. Each attaching member 22 has a studengaging portion 24 which extends from one side of the member it through the opposing portions of the walls thereof for engagement with the stud 20 on the other side of the member. During assembly of the stud and attaching member the tubular member I6 is necessarily flattened at the ends, which imparts a generally oval cross-sectional shape to the intermediate portion thereof.

The tubular member 18 is provided with a'pair of snap fastener socket members 26 which are assembled onto the ends of the member by pronged attaching members 28. The prongs 36 of the attaching member extend from one side of the tubular member 18 through opposing portions of the walls for engagement with the socket, which also results in the ends of the tubular member being flattened, and imparts a generally oval shape to the intermediate portion of the member.

To receive the cord ends l2, cord-receiving apertures 32, 32a, and 34, 34a are provided in the members i6 and I8 respectively. The apertures in each member are disposed through opposing portions of the walls so that a cord end may be inserted through both apertures to extend transversely of the member. the cord-receiving openings are also preferably so disposed that the cord extends across the longer axis of the oval-shaped intermediate portion, so that the portion of the cords extending through the member are substantially parallel when the members are superimposed and snapped together.

The cord-receiving openings are of a predeter-- mined size in relation to the diameter of the cord to be inserted therein so that although the members are slidable therealong, there is sufilcient frictional engagement between the cord and the member so that the member may retain itself in a predetermined position on the cord.

The device is particularly adapted for use on a drawstring l4 such as might be used to tighten the hood of a snowsuit or the like. The members i6 and I8 are assembled into the ends 12 of the cord by inserting the ends through the cord-receiving openings, and during use of the garment, the members will be superimposed and snapped together, and thereafter the slider assembly may be moved up and down on the cords to tighten or loosen the drawstring. When the garment is to be removed, the cord ends may be completely separated by unsnapping the members l6 and 18 from each other, without sliding the members down the cords. This feature is particularly desirable, since when such garments are worn under adverse weather conditions, the cord frequently becomes knotted or fouled with ice, making it difficult to loosen the drawstring by moving the slider along the cord.

A number of materials have been found suitable for use in making the members l6 and I8, which are suffioiently flexible and relatively soft so that excessive Wear of the cords will not result from continued use. For example, rubber or rubber-like materials, and the softer and more flexible varieties of plastic have been found suitable. In any of these materials, a durometer indentation hardness of about 70.is desirable. If the material is to be used on garments to be worn in extremely cold weather, it is preferred to form the members of polyvinyl chloride, since such.

material is capable of withstanding low temperatures without becoming brittle.

Since certain obvious changesmay; be madaim the device without departing from the scope of the invention, it is intended that all matter-contained herein be interpreted in an illustrative, and not in a limiting sense.

I claim:

A slider for receiving a pair of substantially parallel oordsor the likein frictional engagement so as to be slidable therealong, comprising a .pair of elongated members. having cooperating snap fastener parts. disposed on thesidesso that said members may be disposed alongside each other and snapped together colateral relation, each of said members having an opening extending transversely therethrough to receive-the cords so 4 that said members may be slid in the same direction along each of the cords while the members are snapped together, and said cords may be separated from each other without being removed from said members by unsnapping said members from each other, said members being formed of a resilient organic plastic tube, said tube being flattened at; the ends,, said snap fastener parts being mountedz'on the fl'attened ends, and said openings for the cords extending transversely through the tube in a direction substantially parallel to the plane of the flattened ends.
