NON-METALLIC FIBER CABLE HOISTING GRIP WITH CLOSED AND OPEN-MESH CONFIGURATION AND METHOD OF ASSEMBLY AND PLACEMENT

Abstract

A cable hoisting grip comprising open- and closed mesh portions, the closed-mesh body embodiment comprising a lower end and an upper end extending into an eye portion, the ends comprising mesh openings. To hoist, a cable is inserted into the lower portion's opening through the mesh's body so that it extends through it. The open-mesh body embodiment comprises mirror-image lateral ends. To hoist, a cable is placed between the open-mesh body portions' lateral ends so that the mesh can envelope it. A lace is weaved into the open-mesh body lateral openings and secured by knotting each end closing the mesh. A lifting means is attached to the eye, as the hoisting grip rises, the weight of the cable elongates the mesh portion and decreases its diameter securing the cable via radial pressure. the hoisting grip is attached to the lifted and tower-positioned cable so that it permanently supports the cable.

DETAILED DESCRIPTION OF THE INVENTION

[0035] Objects, advantages and novel features, and further scope of applicability of the present invention will be set forth in part in the detailed description to follow, taken in conjunction with the accompanying drawings. The objects, advantages and novel features, and further scope of applicability of the present invention will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

[0036] Specifically, the detailed description below refers to a cable hoisting grip comprising a mesh portion (1), the mesh portion comprising a lower end (2), a body (3) and an upper end (4). The lower end (2) and the upper end (4) both comprise mesh openings (5) and (6). The upper end (4) of the mesh portion (1) continuously extends into an eye portion (7). To provide the hoisting effect, a cable is inserted into the opening of the lower portion of the mesh (5), through the body of the mesh (3) so that it extends through the opening (6) of the upper portion of the mesh (4). A lifting means (8) is attached to the eye so that as the hoisting grip rises, the weight of the cable causes the mesh portion of the grip to elongate as shown and illustrated in FIGS. 3 and 4. As the mesh portion elongates, because of its mesh configuration, its diameter decreases thus causing radial pressure on the cable. The radial pressure prevents the cable from sliding down in the hoisting grip. Once the cable is lifted and positioned on the tower structure the hoisting grip is attached to the structure, permanently supporting the cable.

[0037] In the embodiment of the invention comprising an open-mesh mesh body portion (1a), the mesh portion comprises a body (3a) which comprises a lower end and an upper end and identical, mirror-image lateral ends (9) and (9a), with each lateral end comprising an edge and wherein each edge comprises multiple, adjacent mesh openings located and running along each edge of the lateral ends from each lower end and extending up to each upper end.

[0038] To provide the hoisting effect, a cable(s) is placed between the open-mesh body portions' lateral ends (9) and (9a) so that it can be firmly and tightly enveloped by the mesh. A closing lace (10) made of the same material and coating as the mesh portion, the closing lace comprising two end portions (11) and (11a) and a middle portion (12) is inserted and weaved and laced into each subsequent and opposing lateral side mesh opening located along the edges of the open-mesh body's lateral ends (9) and (9a), akin to the way shoe laces are weaved into shoe eyelets, resulting in a configuration whereupon the closing lace is weaved into the openings, the laces' middle portion (12) is located at and connects one end of each lateral side with the opposite and corresponding end of the other lateral side, and the laces' end portions (11) and (11a) are located exiting the last opening located at the upper end of each lateral side. The closing lace is then secured tightly in place by knotting each end resulting in a structure now comprising a closed-mesh body configuration.

[0039] A lifting means (8) is attached to the eye (7) so that as the hoisting grip rises, the weight of the cable causes the mesh portion of the grip to elongate as shown and illustrated in FIGS. 5, 7 and 8. As the mesh portion elongates, because of its mesh configuration, its diameter decreases thus causing radial pressure on the cable. The radial pressure prevents the cable from sliding down in the hoisting grip. Once the cable is lifted and positioned on the tower structure the hoisting grip is attached to the structure, permanently supporting the cable.
