1、Designation: F1363 07 (Reapproved 2017) An American National StandardStandard Guide forReduction of Risk of Injury for Archery Overdraws1This standard is issued under the fixed designation F1363; the number immediately following the designation indicates the year oforiginal adoption or, in the case
2、of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers the function of archery overdraws andsuggests a limited number of geometric
3、 configurations thatcould decrease the potential risk of injury to the archer.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental pra

Significance and Use3.1 This guide covers only the most obvious areas ofoverdraw

This condition is dependenton the length of the arrow
9、and lies entirely within the controlof the individual archer. The length of the arrow must beselected so that the arrow will not be drawn past the arrow rest.It is generally possible, within functional limits, to providesome hardware design to further guard against the possiblehazard from negligence
10、 on the part of the user.4.2.2 The location of the arrow rest in relation to the aft endof overdraw is shown in Fig. 2.4.2.3 An arrow rest placed at the extreme aft end of theoverdraw (Fig. 2(A) may allow the arrow to fall off the restand overdraw platform if an archer draws past his or her drawleng
11、th.4.2.4 The arrow rest location at the forward end of theplatform is shown in Fig. 2(C). In this location the arrowdisengagement from the rest should be contained by theplatform to a greater degree than in Fig. 2(A).4.3 Arrow Containment Methods Without Full Enclosure ofthe Arrow:4.3.1 A relatively
12、 wide horizontal plate extending beyondthe wrist and knuckles of the bow hand may provide adequatearrow containment if the arrow disengages from the rest (Fig.3).4.3.2 A relatively high vertical plate left of the arrow (for aright-handed archer) may provide adequate containment for anarrow raised up
13、ward from the arrow rest (Fig. 4).4.3.3 It should be noted that most overdraw designs are acombination of Figs. 3 and 4 to some extent, and they providevarious degrees of arrow containment.5. Suggested Guidelines5.1 Vertical Plane:5.1.1 An open system with a relatively high vertical platecould provi
14、de adequate levels of arrow containment (Fig. 4),should the arrow become disengaged from the rest.5.1.2 A fully enclosed overdraw system that surrounds thearrow would shelter the arrow circumferentially at all points inthe vertical plane (Fig. 5) and provide a still greater degree ofarrow containmen

18、aged from the arrow rest, even in afully vertically enclosed system.5.2.2 The length of an arrow overhanging in front of the restat full draw should be long enough to prevent disengagementof the arrow if the archer pulls past his or her draw length (Fig.6). On a compound bow, this distance may be ma
19、de equal to orgreater than the maximum distance that the bow can bereasonably drawn. An extra-long arrow would give a greaterdegree of arrow containment.6. Overdraws on Bows without Draw Stops or DefinedValleys in the Force-Draw Characteristics6.1 Such bows can be drawn further than compound bowspas

Alignment of Overdraws With Sight Window and BowShelf7.1 To minimize the possibility of arrow impact against thebowhandle, it is critical that the horizontal plate of theoverdraw b
