This disclosure generally relates to safety devices for window coverings.
Window blinds, shades, and curtains are available in a variety of styles. Window treatments often have a top rail or rod, and, in the case of many horizontal blinds, a bottom rail. Shading material either hangs from the top rail, or between the top and bottom rails if there are multiple rails. The shading material can be vertical or horizontal slats, paper, mesh, or fabric. Pull cords are often used to adjust the amount of material covering the window to permit more or less light to pass through the window. Many window coverings use long looping pull cords or two-end pull cord that dangle in front of or beside the window covering. Because these cords dangle near the floor within children's reach, they present a household danger. People, and especially children, can be strangled, choke, or become tangled in dangling pull cords.
Some devices that keep cords out of children's reach require that the device be mounted on a wall with screws or adhesive, and are therefore aesthetically unpleasing, some require tools to install or uninstall, and can damage walls to which they are affixed. Further, many currently-available devices use pulleys, wheels, or complicated multi-piece assemblies that make the devices difficult to use and more expensive to make.
The device can be made as an inexpensive, simple, one-piece blind cord winder device that does not require mounting or complicated methods for winding cords to keep them out of children's reach.
The blind cord winder described here can be simple, inexpensive, and can be made as a one-piece device for raising dangling pull cords out of children's reach by allowing pull cords to be wound around and secured to the device.
The blind cord winder includes, and can consist or consist essentially of, a top portion, a bottom portion, and a spindle. The top and bottom portions are separated by the spindle. Pull cords are wound around the spindle and the top and bottom portions hold the wound cord in place. The bottom portion can have slots, which can terminate in notches, to help secure ends of pull cords to the device.
The size of the blind cord winder can vary depending on the length and thickness of the pull cord it is configured to accept. The blind cord winder can be any general shape, and can be made out of a substantially rigid material such as plastic.
The following figures are provided for the purpose of illustration only and are not intended to be limiting.
A blind cord winder device 10 around which pull cords (e.g., of the type commonly used to open and close window coverings) are wrapped. A portion of a pull cord is wound around and secured to the device 10 to keep ends of cords out of children's reach to prevent children from choking on, being strangled by, or tangled in dangling cords. The blind cord winder 10 hangs freely from cords as shown in
Referring to
The blind cord winder 10 can have any general shape. For example,
The dimensions of the top and the bottom portions 12, 14 are greater than that of the spindle 16. However, the dimensions of the top portion 12 can be greater than, less than, or the same as the dimensions of the bottom portion 14. The thickness of the spindle 16 and size of the top and bottom portions 12, 14 vary depending on the length and thickness of the cord it is configured to accommodate. For example, a thicker cord, such as a chain or beaded pull cord, may require a larger top portion 12, larger bottom portion 14, or a smaller spindle 16 than a pull cord made of thin rope. As shown in
The top portion 12, bottom portion 14, and spindle 16 can be fabricated as a single piece or as multiple components permanently joined by adhesive or some other fastening means. The blind cord winder 10 can be made of any substantially rigid material, preferably, but not necessarily a substantially rigid, light-weight material. In a one embodiment, the blind cord winder 10 is made of plastic, such as acrylonitrile butadiene styrene plastic, commonly known as ABS plastic. In another embodiment, the blind cord winder 10 can be made of hard rubber, metal, wood or any other substantially rigid material.
As will be apparent, the embodiments can be provided forms other than those specifically disclosed above. The particular embodiments described above are, therefore, to be considered as illustrative and not restrictive. Those skilled in the art will recognize, or be able to ascertain, equivalents to the specific embodiments described herein. For example, the top portion 12 and bottom portion 14 of the blind cord winder 10 can be configured to have any general shape capable of holding pull cords in place, including an oval, circular, rectangular, triangular, or square-shaped. The top portion 12 and bottom portion 14 can be the same or different shapes. Similarly, the width and overall shape of the spindle 16 can vary.
