Definitions

  • This invention relates to buckle's. Specifically this invention relates to molded plastic buckles with improved guiding and locking action and adjustable web securing features.
  • Such central guide arm added substantial weight to the buckle and the requisite pressing of the side arms against the central arm was unwieldy in actual use, particularly so where the buckle would be employed under adverse conditions such as conjunction with a life jacket or back pack.
  • a buckle in which flexible side arms are self-guiding and do not require manual pinching, and which eliminates the need for a central guide arm or bar.
  • a molded plastic buckle is provided with male and female interlocking members wherein the male member is formed with self-guiding flanged resilient arms, and wherein the flanged portion of the arm is shaped so as to be self-guiding and slidably fitting into specifically sized channels formed in the female member.
  • the molded plastic buckle is formed with an elliptical cross bar for adjustably holding a web to one of the members.
  • Buckle 10 is formed of a molded plastic male member 11 and a molded plastic female member 12.
  • Male member 11 is formed with a body portion 13 from which extends a cross-member 14.
  • a pair of opposed similar arms 15 are integrally molded with cross-member 14, and flex about junctures 14 a inwardly, towards each other to a limited degree, but do not touch each other on flexing, for purposes hereinafter appearing.
  • Arm 15 is formed with stem 16 terminating at its foreward end with flange 17.
  • Stem 15 is of generally rectilinear cross-section.
  • Flange 17 is formed with upper and lower peripheral rims 19a and 19b, respectively, in turn forming an inner rounded portion 20, an inner straight portion 21, a rounded foreward leading portion 22, an outer oblique portion trapezordial connecting member 26 is formed with flange 17 and provides recesses 27a and 27b for rims 19a and 19b, respectively.
  • Body portion 13 is formed with H-shaped portion 28 having opposed legs 3G and 31:
  • An elliptical cross bar 32 is transversely disposed between and integrally formed with legs 30 and 31.
  • Elliptical bar 32 is angularly disposed with respect to top and bottom surfaces 33 and 34 so that the major axis 35 of the ellipse cross-section 36 is at an angle A of about 57° with respect to surfaces 33 and 34 (FIG. 5). This angular disposition of an elliptical cross bar was found to be important in retaining a web 40, as will be more fully explained here- .inafter.
  • the cross-member 41 of portion 28 forms a second transversely disposed cross-bar 42, which is formed from bottom surface 34, surface 43 at 90° with respect to surface 34, and surface 44 at 45° degrees with respect to surface 34 (FIG. 5). It is to be noted that these angled surfaces 34, 43, and 44 are juxtaposed nearest to one end portion 46 of the ellipse on the major axis 35, and is most remote to the other end portion 47 of the ellipse on the major axis 35. Minor axis 48 is slightly less than parallel to surface 44.
  • Portion 28 is also formed with a plurality of parallel grooves 49 formed in bottom surface 34.
  • a tab portion 50 extends outwardly from the male body portion.
  • Female member 12 is formed with a body portion 51 having opposed cut away portions 52. End 53 of portion 51 is formed with tapered side walls 54, which extends from edge 55 to edge 71 of cut-away portion 52. Opposed upper and lower walls 56 and 57 are formed with side walls 54 so as to form insert opening 58. Opposed pairs of upper and lower ribs or guide tods 59 and 60 depend from walls 56 and 57 respectively, so as to form flanqe-quide channels 61. Ribs 59 and 60 have rounded opposed edqes 62a and 62b, and parallel side walls 63 and 64, respectively.
  • Female body portion 13 is also formed with end portion 65 which is formed with transversely disposed recti- lincar slots for fixedly holding the closed looped end 67 of web 40 around tab bar 68.
  • End tab 68 extends outwardly from end portion 65.
  • the user grips the sides 92 of body portion 13 at the H-shaped member with one hand and grips the sides of 69 of female body end portion 65 with the other hand.
  • the user advances the male member 11 towards the female member 12 so that rounded leading foreward edges 22 enter the respective guide channels 61.
  • surfaces 17 and, in turn, 24 slidably contact walls 54 so as to cause arms 15 to flex towards each other to a limited degree (FIG. 3).
  • This arm flexure continues until inner surfaces 21 slidably contact rib walls 63 and 64 whereby the arm flanges are self-guided into the channels.
  • This insertion continues until flanges 17, particularly surface 24 passes edge 71, at which point the arms snap flex away from each other and reside substantially but not entirely with the cut-away portions.
  • the buckle is then in the locked mode (FIGS. 2, 5, an 6).
  • each guide channel 61 is composed of two portions, namely, a flange receiving portion 79, comprising opposed walls 80 and 81, which are sized to receive the flange in a close tolerance fit, and a flange guiding portion 82 formed of rib walls 63. 64, and opyosed walls 93 and 94, for guiding the flange into the flange receiving portion 79 (FIG. 6).
  • rims 19a and 19b at inner surfaces 21 reside within the female body as at portion 75 (FIG. 2). This close fitting of the flange and stem prevents twisting of the flanges 17 and stems 16, in the locked position.
  • Web 40 has a fixed end 67 and free end 77.
  • the free end 77 overlies surfaces 96, 47, and 97 of the elliptical bar 42, and passes downwardly and over the 90° angle of the second bar 42, and across the grooves 49, and underlies portion 91 of the web 40. In this manner, free end 77 is secured to the male member.
  • the tab 50 or body 13 is lifted so as to relieve the stress exerted between the elliptical bar and the angled second bar, and the web free end pulled to the desired length, and the tab or male body is then released.
  • the presence and orientation of the elliptical bar in relation to 90° angled bar provides a secured holding of the web at the desired web length.
