According to this embodiment a flange 332 defined by a plate or the like is secured to the shank 322 such as by welding or the like. The flange 332 has an opening 334 formed therein end which defines a clasp-receiving aperture. This provides a further point of attadiment to further enhance the safety associated with the device hereof. Referring now to Figs. 10-12, and generally, depicted at 410, is a spring loaded snap for use with the safety harness hereof. The snap 410 is associated with a deep 412 to define an assembly 408. Preferably. the snap 410 is integrally formed with the deep 56 or the like. The snap 410 impedes or prevents a belt from slipping therepast. The snap 410, as shown, comprises a housing 416, a rim member 418 disposed in the housing and meens 420 for biasing the cam in#o a locking position. The housing 416 is defin~d by a body member 420 having an angularfy inclined or romped splined surface 422, a pair of end walls 424, 426 respectively and a bottom wall 428. The ramp surface 422, the end walls 424 and 426 and the bottom wall cooperate to define an open housing. ~;;3 Registering apertures 430 and 432 are respectively formed in the end walls. A pivot pin 434 extends traverses the open irtterior of the housing and is inserted into the registering apertures and held in position thereat by any suitable means. The means 420 preferably, comprising a spring, is joumalled onto the pivot pin 434 and is held in position by insertion into suitable apertures formed in the bottom wall, Surmounted onto the pivot pin is the calm member 418. As shown particularly in Figs. 10 and 11 the cam member comprises a block 436 having a aenhal opening 438 in which is disposed the spring 420. The block 436 has a throughbore which is in registry with the central opening 438 only through which the pivot pin 434 projects to pivotally mounted the cam thereonto. The block 436 has an in'egular or rammed surtace 442 which is normally biased, by the spring 420, into engagement with the splined tamped surface 422. The belting 414 may be threaded therepast against the force of tile spring in the dinsction of the an~ow 444 against the bias. Acounterforce coincident with the force of the spring, will cause the cam to rotate into the tamped surface causing the belting to be sandwiched between the tamped surface 422 and the cam 442 thereby locking the belt in position and preventing slippage therepast, The snap thus adds a further safety factor to the present device. The snap may be formed from any suit~le material such as a durable, hard, rigid plastic, metal or the ~ike. Referring now to Fig. 13, there is shown therein a preferred form of deployment of the present invention. As shown, a tree 510 has a plurality of J .tree steps strappingly secured therearound and denoted at 512, 514, 516, 518, etc. each of the tree steps has a provision for attachment thereto of at least two shape. Secured to hamBSS 520 is a first strap or tether 522 of a first length and a second strap or tether 524 of a second length, one of the lengths being shorter than the other. In use, and beginning with step 512 being designated as the first step, the present safety apparatus is utilized as follows:(a) the first step 512 is severed about the tree 510 and the short strap is seared thereto as the user st~ps thereunto;(b) the second step 514 is then, installed, (c) the longer strap is, assured to the second step, via one of the apertured tlanges, (d) the short strap is disconnected from the first strap, (e) the user steps up to the second step, (f) the user, then, secures the shorter strap the second slap;(g) the third step 516 is, then, secured to the tree, (h) ~e longer strap is, then, disconnected from the second step and attached to the third st~p, end (i) the sequence is repeated during ascent. For descent the procedure is r~versed. By using short and long straps, the user is kept dose to the tree during irlst~llation of the next ssoending step and the longer strap thereto. Thus, during the entire process the user is continuously strapped to a step. It is tn be appreciated that the present safety device secures the user to the tree or other support continuously during either ascent or descent by the aitemating connecting and disconnecting of the connectors to associated tree steps placed in the support Having, thus, described the irnention, what is daimed is.
