1、Designation: F 1363 07An American National StandardStandard Guide forReduction of Risk of Injury for Archery Overdraws1This standard is issued under the fixed designation F 1363; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the
2、year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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 configurations
3、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 and health practices and determine the applica
4、-bility of regulatory limitations prior to use.2. Terminology2.1 Definitions of Terms Specific to This Standard:2.1.1 acceptable overdrawan acceptable configuration ofan archery bow overdraw should provide partial or fullcontainment for the arrow if the arrow becomes disengagedfrom the arrow rest.2.
5、1.2 archery overdrawany design configuration, integralor added, that permits the extreme forward tip of an arrow to bedrawn past the pivot point of the hand grip.3. Significance and Use3.1 This guide covers only the most obvious areas ofoverdraw safety.3.2 This guide is not intended as a comprehensi
6、ve analysisof the subject.4. Arrow Containment4.1 Vertical Plane:4.1.1 In the vertical plane, Fig. 1 shows that increasinglevels of arrow enclosure will provide increasing levels ofarrow containment.4.1.2 A higher degree of arrow containment may beachieved by the position in Fig. 1(D) than by that i
7、n Fig. 1(A).4.2 Horizontal Plane:4.2.1 It must be recognized that an arrow can be drawn pastthe support of the arrow rest, regardless of the type of bow andwhether or not it has an overdraw. This condition is dependenton the length of the arrow and lies entirely within the controlof the individual a
8、rcher. 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 on the part of the user.4.2.2 The location of the arro
9、w 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 drawlength.4.2.4 The arrow rest location at the forward end of
10、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 wide horizontal plate extending beyondthe wrist and kn
11、uckles 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 upward from the arrow rest (Fig. 4).4.3.3 It should be no
12、ted that most overdraw designs are acombination of Figs. 3 and 4 to some extent, and they providevarious degrees of arrow containment.1This guide is under the jurisdiction of ASTM Committee F08 on SportsEquipment and Facilities and is the direct responsibility of Subcommittee F08.16 onArchery Produc

14、28-2959, United States.5. Suggested Guidelines5.1 Vertical Plane:5.1.1 An open system with a relatively high vertical platecould provide 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
15、 shelter the arrow circumferentially at all points inthe vertical plane (Fig. 5) and provide a still greater degree ofarrow containment.5.2 Horizontal Plane:5.2.1 In the horizontal plane (looking down on the archer),an arrow might be disengaged from the arrow rest, even in afully vertically enclosed
16、 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 made equal to orgreater than the maximum distance that the bow
17、 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 bowspast their recommended draw length. An adequate arrowoverhang f
18、or a compound bow may not be sufficient for arecurve bow.7. 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 be in line with or higher than the bow shelf. It is alsosugge
19、sted that the side plate be in line with or to the left of thesight window (for right-handed shooters) (Fig. 7).8. Instructions8.1 It is suggested that the manufacturer issue instructionswith each overdraw unit stating that the recommended lengthof overhang from the rest for an arrow is a minimum of
