Abstract: The device is a cord lock having an outer arm (10) and an inner arm (11) integrally connected by a hinging member (12). The device is constructed of resilient material, such that outer arm (10) and inner arm (11) will flex into slidable contact with each other when pressure is applied to their sides, and will flex back, away from each other, when the pressure is released. An outer arm opening (13) and inner arm opening (14) are located through the free ends of outer arm (10) and inner arm (11) respectively. To engage the device, outer arm (10) and inner arm (11) are urged together until outer arm opening (13) and inner arm opening (14) are in line with each other, and a cord is then threaded through the openings. The urging-together pressure is then released, causing outer arm (10) and inner arm (11) to slide back to a position wherein the cord is pinched between outer arm opening (13) and inner arm opening (14), and is prevented from moving.

Abstract: My invention is a device for preventing children from untying their shoelaces. It can be quickly and easily installed and removed by adults of any age.A snap-fit cap, attached to a well, forms the main body of the device. To install, the device (in an open position) is slipped between the knot and the shoe, using a slot incorporated into the well.The knot and lace ends are placed into the well, and the cap is then fitted over the well, to securely contain the knot and lace ends and prevent removal. The cap may only (and then may easily) be removed when a indicator tab on the cap is aligned with the slot in the well.Removal is basically the reverse of installation, except that the cap is rotated to line up its indicator tab with the slot in the main body of the device. The cap may then simply pulled off in one quick, easy motion. The device is then slipped off the shoe and laces.There are several advantages of this invention over the prior art.
