DETAILED DESCRIPTION

(10) In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and like numerals represent like details in the various figures. Also, it is to be understood that other embodiments may be utilized and that process or other changes may be made without departing from the scope of the disclosure. The following detailed description is not to be taken in a limiting sense, and the scope of the invention is defined only by the appended claims and their equivalents. In accordance with the disclosure, a reusable clamping device is hereinafter described.

(11) As shown in FIGS. 1-8, the reusable clamping device 10 is illustrated. The reusable clamping device 10 may be made in multiple sizes to accommodate nearly any size application. One of the primary uses of the reusable clamping device 10 is to provide a more aesthetically pleasing alternative to metal hose clamps. For example, the reusable clamping device 10 may be used on a machine missing a metal collar, which is used to prevent a shaft sliding when in use. The reusable clamping device 10 may be used to be clamped or fastened to the machine to prevent the shaft from sliding during use. Advantageously, unlike single-use wire and cable ties, once the reusable clamping device is used, it may be easily removed from the machine and re-used on a different machine or for a different clamping or fastening purpose.

(12) Turning to FIG. 1, the reusable clamping device includes a cylinder 20. The cylinder may be made of plastic or another suitable rigid, yet relatively flexible material. As perhaps best shown in FIG. 6, the cylinder 20 includes an opening 30, such as a slot on the exterior portion of the cylinder. A plastic loop 40 may be connected to the cylinder 20 at one end and the opposite end of the loop may be inserted into the opening or slot 30. The plastic loop 40 may be made of 0.125 inch thick plastic. The opposite end of the loop may be trimmed and the corner may be rounded or tapered such that it fits tight and snugly within the slot 30. The opening or slot 30 is slightly larger than the loop such that a tight fit is ensured. The top of the inserted end of the loop (with the tapered end) fits right under the attached end of the loop. In order to tighten the device, a person may use his/her hands or even a tighter fit is desired, a pair of round tip vise grips may be used.

(13) The device 10 further includes a screw 50 may be inserted inside the cylinder 20. The screw 50 may be a recessed, hex head screw that will be countersunk into the clamp when tightened. Although other types of screws may be used, the recessed hex head screw effectively grips the plastic of the cylinder when it is tightened. In more detail, the hex head screw is easy to tighten with one hand while gripping the clamp tight with the other hand. When tightened, the hex head screw is totally inside the base to eliminate the possibility of anything snagging or catching on it. The hex head screw also has a ring on the bottom of it which will grip tighter on the loop to prevent the loop from slipping back out. The interior portion of the cylinder 20 may be threaded such that it mates with the screw 50 when the screw is inserted.

(14) In use, the clamping device 10 including a screw 50, such as a recessed hex head screw and cylinder including slot and an associated loop may be used for multiple applications, including as a hose clamp or a binding device. The method of using the clamping device includes inserting the recessed hex head screw into the plastic cylinder and tightening the recessed hex head screw. The method further includes wrapping the associated loop around the item to be clamped. Once the associated loop is wrapped around the item, one end of the associated loop (the tapered end) is inserted into the slot on the cylinder. If desired, a person may loosen the recessed hex head screw such that the recessed hex head screw and the plastic cylinder may be removed from the item and reused. As shown in FIGS. 4a-4c, the free end of the loop fits into the cylinder above the attached end of the loop. Alternatively, in FIGS. 5a-5c, the free end of the loop may fit into the cylinder below the attached end of the loop.

(15) Advantageously, the clamping device may be used temporarily or as a substantially permanent binding. Unlike wire tires, the clamping device may be easily loosened and unfastened, so that it may be reused. For example, many times a person may decide that the item being clamped needs moved or re-positioned and the clamping device may be easily loosened and unfastened such that the item may be moved to a more suitable location.

(16) The foregoing descriptions of various embodiments are provided for purposes of illustration, and are not intended to be exhaustive or limiting. Modifications or variations are also possible in light of the above teachings. The embodiments described above were chosen to provide the best application to thereby enable one of ordinary skill in the art to utilize the disclosed inventions in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention.
