Abstract

A mechanical cord lock forming a non-slipping loop in an elastic cord such as elastic bungee cord employed in a vehicle restraining net is disclosed. The connector includes two releasably engageable parts one of which has concave sidewalls formed on opposite sides thereof and a central wall formed intermediate the concave sidewalls. The second part has spaced concave sidewalls each with a pair of depending legs formed on opposite end walls which when mated with the first connector part defines two tortuous paths through the connector parts which ensure that the elastic cord lengths that are placed therethrough in a stretched position remain in such position without slippage.

Claims

1. An elastic cord lock for securing two sections of cord and preventing slippage therebetween, the cord lock comprising:

two body portions each having sections which, joined together, define tortuous paths for each of the cord sections, the tortuous paths being sized such that the cords must be stretched to be positioned within such tortuous paths, wherein the body portions comprise;

a female body section and a male body section, the female body section having opposed concave walls terminate at the opposite ends defining cord openings through which said cord extends through said female body;

said male body section comprising opposed concave walls and a centrally disposed I-shaped web member which is received by said female body section to divide said female body section into two tortuous paths for receiving said cord sections, the distance between said I-shaped member and the opposed walls of said female body section defining an interference fit to receive the stretched portions of said stretchable cords; and

means for securing the body portions to each other to lock the cords in position.

2. The cord lock defined in claim 1, wherein said body portions are provided means for lockingly engaging one to the other such that said body portions are releasably connected.

3. The cord lock defined in claim 2, wherein said body portions are made from a plastic material.

4. The cord lock defined in claim 3, wherein said female body section has apertures formed in said opposed concave walls and said male body section has flexible projections disposed in said opposed concave walls with lateral shoulders which are sized to snap-lockingly engage said female apertures when said male body section is joined to said female body section.

5. The cord lock defined in claim 4, wherein said female body section has a plurality of alignment pins formed on said concave walls and said male body section has a plurality of recesses formed on the base thereof which are adapted to receive said alignment pins to ensure proper alignment between said female and male body sections when secured to each other.

6. The cord lock defined in claim 1 wherein the male body section has an interior surface, and wherein the cord lock further comprises a projection extending outwardly from the interior surface for confining the cord sections.

7. The cord lock defined in claim 6 wherein the projection is cylindrically-shaped.

8. The cord lock defined in claim 6 wherein there are two projections.

9. The cord lock defined in claim 1 wherein the male body section has an interior surface and the I-shaped member has two ends, and wherein the I-shaped web member terminates in a triangularly-shaped web extending from each end of the I-shaped web member to the interior surface.

10. The cord lock defined in claim 1 wherein the two sections of cord comprise portions of a continuous loop which extends from one side of the lock, the continuous loop being formed at one corner of a flexible net, the net being positioned across a portion of a vehicle trunk, the loop being attached by a fastening member to the vehicle trunk.
