DESCRIPTION OF THE PREFERRED EMBODIMENT

(23) A cable tying device according to a preferred embodiment of the present invention will now be described with reference to FIGS. 1a to 13c of the accompanying drawings. The cable tying device 10 includes a head member 20 and a tying strap 30 configured to secure a work piece 12 to another or even components of the same work piece.

(24) With reference to FIGS. 1a, 1b, and 3 to 7b, the head member 20 of the cable tying device 10 includes an outer end 22 and an opposed inner end 24 and defines an aperture 26 adjacent the outer end 22 having a generally rectangular configuration. The aperture 26 may extend completely between top 25 and bottom 27 walls of the head member 20. The head member 20 further defines a channel 28 having a generally V-shaped configuration in operative communication with the rectangular aperture 26. The channel 28 may be referred to as having a triangular configuration or as being a notch. The head member 20 may have an L-shaped configuration defining an inlet 21 at a lower end and an outlet 23 at an upper endboth, however, being adjacent the outer end 22 of the head member 20. It is understood that the inlet and outlet are descriptive of where the tying strap 30 enters and exits the aperture 26 and channel 28, as will be further described below.

(25) The tying strap 30 includes a base strip 32 having a generally flat or planar configuration and having a smooth outside surface 36. A proximal end 38 of the base strip 32 is coupled to the inner end 24 of the head member and a distal end 40 of the base strip 32 is displaced from and opposite the proximal end 38. In one embodiment, the distal end 40 may have a truncated configuration although a pointed tip configuration would also work. The tying strap 30 includes parallel side edges 42 extending between the proximal end 38 and distal end 40 so as to define a width of the base strip 32. The tying strap 30 may be constructed of a flexible plastic material so that it may be formed into a loop for insertion into and through the head member 20 as described below.

(26) The tying strap 30 also includes a toothed portion 44 extending longitudinally between the proximal end 38 and distal end 40 of an inside surface 34 of the base strip 32, the toothed portion 44 preferably being positioned about midway between the side edges 42 and having a narrow width profile. The base strip 32 is wider than the toothed portion 44 such that the base strip 32 extends laterally on both sides of the toothed portion 44. In a preferred embodiment, the toothed portion 44 has a generally V-shaped or triangular configuration having a plurality of teeth 50 extending away from the base strip 32.

(27) It is understood that the base strip 32 and aperture 26 have generally rectangular configurations and substantially similar dimensions. In like manner, the toothed portion 44 of the tying strap 30 and the channel 28 have generally V-shaped or triangular configurations and substantially similar dimensions. In other words, the head member openings and the tying strap 30 are complementary structures such that the head member 20 may selectively receive the tying strap 30 therethrough when inserted distal end 40 first.

(28) Now, more particularly, the toothed portion 44 includes a first side wall 46 that is inclined or angled inwardly relative to the base strip 32 and a second side wall 48 that is angled inwardly toward the first side wall 46. Together, the side walls are joined at an apex 49 displaced from the base strip 32. Stated another way, each side wall includes a lower end adjacent the inside surface of the base strip 32 and spaced apart from one another. The apex 49 is opposite respective lower ends. The toothed portion 44 includes a generally triangular shaped cross-section.

(29) Similarly, the V-shaped channel 28 includes a first surface having an inclined or angled surface that includes a plurality of ratchet teeth 29 spaced apart along respective surfaces. The channel 28 also includes a second surface having an inclined or angled surface that includes a plurality of ratchet teeth 29 (intentionally numbered the same as the aforementioned ratchet teeth). It is understood that the channel 28 is configured to receive or mate with respective ratchet teeth 29 when the tying strap 30 is inserted distal end first through the aperture 26 of the head member 20.

(30) The plurality of ratchet teeth 29 and corresponding teeth 50 of the toothed portion 44 of the tying strap 30 are configured to selectively mate in a ratchet engagement. Specifically, the teeth 50 and the ratchet teeth 29 are positioned in opposite directions and configured as a pawl such that the plurality of teeth 50 of the toothed portion 44 are receivable only in a forward direction relative to the plurality of ratchet teeth 29. In the character of a winch, the tie strap 30 is not removable from the aperture 26 of the head member 20 except by severing or otherwise breaking engaged teeth.

(31) In use, the cable tie device 10 is useful to holding items together. Specifically, the flexible tying strap 30 may be looped around cables, hoses, or wires and then secured together by engaging the tying strap 30 to the head member 20. Specifically, once looped around the objects to be secured, the distal end 40 of the base strip 32 is inserted into the aperture 26 of the head member 20 and respective teeth 50 of the toothed portion 44 are received by respective ratchet teeth 29 in the channel 28 in a one-way ratchet engagement.

(32) Accordingly, the generally triangular configurations of the toothed portion 44 of the tying strap 30 and corresponding triangular channel 28 result in a much enhanced and secure fastening mechanism than any fastener previously proposed or implemented.

(33) Another embodiment of the tying device 10 is shown in FIGS. 2 and 8 to 13c of the accompanying drawings and includes a construction substantially similar to that first described above except as specifically described differently below. Primed numerals are used to refer to the same components as previously designatedeven if not specifically repeated below. Specifically, the head member 20 has a configuration that enables the tying strap 30 to be inserted and pulled through at a slightly different angle and to rest more securely upon curved objects being secured.

(34) More particularly, the head member 20 itself may have a more flattened and curved shape configuration defining a hollow interior area. The gently curved configuration of the head member 20 makes it uniquely suited for a bottom wall 27 to rest upon a curved surface of an object being secured, such as a cylindrical hose, hexagonal fastener such as a bolt head or nut (FIG. 2). The head member 20 defines an inlet 21 at an outer end 22 and defines an outlet 23 in a top wall 25 through which the tying strap 30 may be fed through in substantially the same ratcheting relationship described earlier. It can be seen that the outlet 23 is displaced from the outer end 22 such that the tying strap 30 is pulled through at a flatter angle (compared to the angle defined by the aperture 26 and channel 28 of the embodiment first described above).

(35) It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
