Description
Background of the Invention
This invention relates to binding straps used for securing coiled cords of power tools and the like and for retaining drill chuck keys.
There is an inherent problem in power tools of keeping the power cord neatly coiled when the tool is not in use. The operator might use tie stays, individual pieces of string, or anything else which holds the coils together. If these means are not handy, the cord may be tied back upon itself. None of these methods are very efficient.
Means for securing the coiled cord using Velcro strap attachments are known. This type is the most efficient because no tying is required. All that is needed is to bend the strap back over itself and place the mating Velcro surfaces next to one another and attachment is effected, with the coiled cord being held within the enclosure of the strap. The only problem that arises is ensuring that the Velcro strap is readily at hand when the time comes for coiling the cord. There is thus a need or providing a Velcro strap attachment that is permanently affixed to the cord for quick use.
Another problem that exists with power drills is the need for constant use of the chuck key when the drill bit must be changed. Although many holders exist for securing chuck keys within easy reach of the drill, the chuck keys generally fit loosely and may slip out and become lost.
Accordingly, there is a need for a power tool cord binder having Velcro attachment means for holding together a coiled cord, with the binder being permanently fixed to the power cord and further having means to securely hold a drill chuck key within close reach for an operator to use on the drill chuck when necessary.
Summary of the Invention
By mean of the instant invention there has been provided a binding strap comprising an elongate flexible strap having mating Velcro attachment material on both sides. The strap has one end that is split to form a top flap and a bottom flap between which the power cord may be placed for permanent affixation. The stap is provided with holes at the end to receive rivets to close the flaps together around the cord. The strap is designed to bend back over itself, enclosing the coiled cord, bringing the opposite sides in engagement with each other to effect Velcro attachment.
Other embodiments provide for means for permanently securing a drill chuck key at the other end of the stap. The other end is also split into top and bottom flaps which receive the chuck key therebetween. The flaps are provided with holes to accept rivets so that the flaps may be secured together around the chuck key.
It is therefore an object of this invention to provide a binding strap having Velcro attachment means which may be permanently affixed to the power cord, with the binder being able to bend back over itself to enclose the coiled wire.
It is further an object of this invention to provide a binding strap having means to permanently secure at its free end a drill chuck key for ready use by the operator.

Description of the Invention
The binding strap of the instant invention is generally indicated by the numeral 10. It is comprised of a flexible strap member 12 made of cloth or plastic having a top surface 13 completely covered with the hook fastening material sold typically under the trademark Velcro and a bottom surface 15 completely covered with the correspondingly mating loop fastening Velcro material. The Velcro material is described in U.S. Pat. Nos. 2,717,437; 3,000,384 and 3,096,235 and form no part of the invention per se. It is understood that the placement of the hook and loop fastening material on either the top or the bottom surface of the strap may be interchangeable so long as a mating connection may take place between the top and bottom surface.
Each end of the strap is split along its horizontal plane for a short distance to provide a top flap 14 and a bottom flap 16 as shown in FIG. 2. Each end also is provided with a series of four holes such as 17, 18, 19 and 20 as shown in FIG. 1. Holes 17 and 18 are located at the corners of the strap and holes 19 and 20 are placed at a position on the strap where top flap 14 bottom flap 16 are rejoined. Holes 17, 18 19 and 20 receive rivets, such as 22 and 24 shown in FIG. 3, for securing top flap 14 and bottom flap 16 around an object. Stitching means 26 may be substituted for holes 20 and 19 as a means for preventing further splitting of the strap along its horizontal plane. If it is desired to merely secure a coiled cord, line hose or the like which do not use chuck keys, a simpler embodiment provides for only one end to be split into top and bottom flaps.
The binding strap of the instant invention is very simply employed for permanent attachment to an electrical cord of a power tool or other hose-type lines and the like where it may be readily used for securing the coiled cord or line in a net and orderly fashion. The cord 28 is placed between top flap 14 and bottom flap 16 which are secured together around the cord by fastening rivets through the provided holes as shown in FIG. 2. Adhesive means are provided on the respective interior surfaces of top flap 14 and bottom flap 16 to effect a greater seal around cord 28.
Binder strap 10 receives a drill chuck key 30 in similar fashion, the key being secured between the top and bottom flaps 14 and 16, respectively. The key is positioned so that the body of the key lies in the same plane as strap 12 as shown in FIG. 3. The flaps are secured together by fastening rivets through holes 17, 18, 19 and 20. Adhesive means are provided on the interior surfaces of the flaps. The binding strap of the instant invention is adapted to receive various configurations of drill chuck keys, such as those having an L-shape, T-shape and the like.
Another embodiment of the binding strap for receiving a chuck key is shown in FIGS. 5 and 6 which provides for the body of the chuck key to be positioned perpendicularly to the strap. An aperture 32, of sufficient dimension to recieve the drill chuck body 34, is positioned at the center on the area defined by holes 17, 18, 19 and 20. The material of the strap 12 is resilient to allow for expansion of aperture 32 so that chuck key head 36 may pass through when inserting the chuck key. Strap 12 may be split at the end to receive the chuck key as in FIGS. 2 through 4 for this embodiment, or may be split along the horizontal plane a short distance away from the end of the stap as shown in FIGS. 5 and 6. This embodiment is used for chuck keys having a T-shape, so that the arms 38 of the key are held between the top bottom portion of the strap. The top and bottom portions must be pulled apart and twisted slightly out to receive the arms 38 of the key therebetween. Holes 17, 18, 19 and 20 are fastened together by rivets, and adhesive means are provided on the interior surfaces of the top and bottom for a tighter seal in securing the chuck key.
The binding strap is very simply employed to secure a coiled cord or line in that the strap is merely bent back over itself, enlosing the cord or line therein, so that the top and bottom surfaces lined with the Velcro material engage and hold together as shown in FIG. 9. Although use with the electrical cord of a power tool having a chuck key was discussed here, it is to be understood that the binding strap of the instant invention may be used in other applications where a coiled cord or line should be secured and where a key element is employed, such as with the gas lines of oxygen tanks.
Various changes and modifications may be made within this invention as will be apparent to those skilled in the art. Such changes and modifications are within the scope and teaching of this invention as defined in the claims appended hereto.
