referring now to the drawings , with more particularity , wherein like references characters designate like or corresponding parts thereof in several views , there is shown in fig1 an improved cleat , generally designated 10 , which embodies the principles of the present invention . the cleat 10 , as shown , includes an elongated shank 12 having an angularly projected step 14 terminating in a protuberance forming stop designated 16 . as a practical matter , the length of a step is a length sufficient to receive the sole of climber &# 39 ; s shoe while the stop 16 is of a height sufficient to prevent the shoe from slipping laterally off the end of the step 14 . connected to the distal or outer most end of the step 14 is an angular support bracket 18 which serves as a stabilizing heel for the cleat 10 . this bracket also lends vertical support to the step 14 and includes a base portion 20 , extended in coaxial relation with the shank 12 from which projects an inclined support member 22 . this member preferably extends from the lowermost portion 20 to the stop 16 . as shown in the drawings , the cleat 10 is formed from 5 / 16 inch mild steel rod and is of a welded integral construction . however , it is to be understood that the cleat 10 can be formed from any suitable material utilizing any of various suitable fabricating techniques . extended transversely across the end of the shank 12 , in spaced relation with the step 14 , there is a rigid cross bar 24 . this bar includes a mid portion 26 of a substantially arcuate configuration and a pair of end portions 28 and 30 , angularly related to the mid portion . the arcuate configuration of the mid portion 26 of the cross bar 24 is such that nesting of the cross bar against the curved surface of a tree or pole is facilitated while the end portions 28 and 30 thereof project outwardly in mutual parallelism preferably along opposite sides of a common plane of symmetry for the cleat . moreover , it is important to note that the end portions 28 and 30 are also inclined toward the plane of the step 14 for reasons which will hereinafter become more readily apparent . the end portion 28 of the cross bar 24 is provided with a terminal eye 32 within which there is received one end of a chain 34 . this chain is adapted to be placed in circumscribing relation with the trunk of the tree to which the cleat is to be attached . the opposite end of the cross bar , designated 30 , includes a terminal hook 36 for receiving an opening of a link of the chain 34 , after it has been passed about the trunk for purposes of taking a purchase . thus , the cleat 10 is adapted to be suspended from the surface of a trunk of a tree , pole or similar body . as aforementioned , it is important to note that the end portions 28 and 30 of the cross arm 34 extend downwardly as well as outwardly from a trunk of a tree . this permits a moment to be developed about an axis passing horizontally through the uppermost end of the shank 12 as the weight of a climber is applied to the step 14 . thus , the bracket 18 which serves as a heel for the cleat is forced inwardly into frictional engagement with the adjacent surface of the tree for thereby increasing the magnitude of friction developed between the adjacent surfaces of the cleat and tree from which the cleat is suspended . hence , it should be apparent that the heel co - operates with the cross bar 24 for purposes of imparting stability to the cleat 10 . that stability of the cleat 10 , as it is employed , is particularly pg , 6 desirable , can be appreciated when it is recognized that the cleat is used by attaching a series of cleats in mutually spaced relation to the trunk of the tree being climbed . when employing the cleat 10 , for purposes of climbing trees , and similar bodies , the cleat is first placed in a vertical orientation against the surface of the body and the chain 34 then passed around the body in circumscribing relation therewith . the extended end of the chain is secured to the hook 36 by inserting the hook through an opening in a selected link of the chain . a climber now steps upon the step 14 so that his weight is suspended thereby . due to the angular position of the end portions 28 and 30 of the cross bar 24 , a moment is developed about a horizontal axis extending through the uppermost end of the shank 12 so an inwardly directed component of force is developed in the bracket 18 forcing the base portion 20 thereof against the surface of the tree for thus stabilizing the cleat . due to the stabilizing effect of the heel portion 20 , combined with the stabilizing effect of the cross bar 24 , the cleat remains in a substantially fixed relationship with the surface of the body being climbed . the climber now attaches , in a similar fashion , a second cleat to the surface of the body being climbed . this cleat is then stepped upon in the same manner as the previous cleat , with substantially the same effect , and so on . it should , in view of the foregoing , be apparent that the cleat 10 is employed as a practical solution to the perplexing problem of climbing trees , poles and similar bodies without inflicting serious damage through penetration of the surface thereof . although the invention has been shown and described in what is conceived to be the most practical and preferred method and apparatus , it is recognized that departures may be made therefrom within the scope of the invention , which is not to be limited to the illustrative details disclosed .
an improved cleat for climbing trees and the like having a shank adapted to be supported in suspended relation from a chain passed around the trunk and connected to opposite ends of a transversely oriented cross bar rigidly affixed to the uppermost end of the shank . a step projects horizontally from the lower most end of the shank and is stabilized through combined stabilizing effects of a downwardly projected heel and the cross bar .
