Definitions

  • a plastic bundling strap is formed by making an integral plastic casting including a head and a ratcheted strap.
  • the strap is inserted into a locking slot in the head and is locked by a pawl against release.
  • the pawl is integral with the head and fiexes to allow insertion of the strap into the locking slot, after which the pawl locks the strap within the slot against reverse movement.
  • a stop surface for the pawl is formed between the pawl and the head by using an angularly moving core to form a narrow separating slot between the pawl and the head. 'Ihis separating slot allows flexing of the pawl when the strap is inserted into the locking slot, but limits flexing in a reverse direction through the surfaces thereof acting as a stop. The surfaces are at that angle to the pawl and the strap and the locking slot whereby to accept perpendicularly thereof the forces exerted by the pawl developed by attempted release movement of the strap.
  • This invention relates to a bundling strap of the type used for tying together a series of electric wires, cables, tubes or the like. Straps of this class are used in large quantities by automobile manufacturers, airplane manufacturers, and similar industrial users.
  • a bundling strap, and a head for the strap are cast together from a plastic material such as nylon.
  • the head is formed with a transverse locking slot into which the strap of the one piece device is inserted, after it has been wrapped about a series of conductors or tubes that are to be maintained in a bundled position.
  • the strap is ratcheted, and is locked within the slot of the head by a pawl that is cast integrally with the head.
  • the strap after being moved into tightened relation to the bundle, and locked by the pawl in the head, move slightly backward from its fully tensioned and tightened position upon being released.
  • the reason for this is that the end of the strap, after being pulled through the locking slot for holding the wires or tubes in bundled position, must be cut so that no portion of the strap will extend beyond the head. It is naturally difficult to cut the strap very closely to the head. Therefore, if the strap moves rearwardly into the locking slot of the head after being cut and released, it is obvious that no part of the strap will protrude from the head where it may do injury to the operator. It is believed that prior workers in the art have encountered considerable dilliculty in meeting required conditions, because no really effective means for reinforcing the pawl and controlling its movement, have been found.
  • a pawl integral with the head is formed so that it moves relatively to the head on a relatively small neck. This facilitates flexing of the pawl.
  • One side of the pawl is formed as a surface of a narrow slot, the slot being the means through which the pawl is cast integrally with the head While partially separated therefrom for flexing. Therefore, the pawl will swing away from the opposed or base surface of the slot through which it is formed, herein to be termed a separating slot.
  • the narrow separating slot between the pawl and the head at one side of the pawl is formed by a core that is. also part of the core forming the locking slot. Further, the core is shaped so that it is inserted into the mold in an angular position relatively to the locking slot, with the movement of the core in an angular direction forming the separating slot at an angle to the locking slot of the head.
  • the locking slot is of course transverse of the head as is common in the art.
  • the arrangement of the rotating pawl teeth is such that the movement of the teeth into locking position relatively to the strap will move the end of the strap, after it has been cut, into the head of the strap so that there will be no part of the cut strap protruding from the head.
  • FIG. l is a partial vertical view of the integral strap and head of the invention.
  • FIG. 2 is a side View of the assembly of FIG. l.
  • FIG. 3 is an enlarged sectional view illustrating the head of the bundling strap together with the integral pawl, as cast in the mold, as well as the movement of the core utilized for forming part of the locking slot and the pawl.
  • FIGS. 4, 5 and 6 are views similar to FIG. 3 illustrating the strap and pawl in various positions.
  • the bundling strap is indicated generally by the reference numeral 10, and is formed lwith a head portion 11 and a strap portion 12.
  • T he strap portion 12 is formed so that it has small upstanding flanges 1.9 at each side thereof, and between the flanges there are formed ratchet teeth 13, best shown in FIGS. 4, 5 and 6.
  • the straps are adapted to be wrapped around a series of conductors or the like designated generally by the reference letter C in FIG. 2, after which the end of the strap is inserted into 4what is termed a locking slot 14 formed in the head 11.
  • the pawl of the invention is designated by reference numeral 15, and is obviously adapted to coact with the ratchet teeth 13 for locking the strap within the locking slot 14.
  • Pawl is formed with a series of teeth 16, 1'7 and 18, and these teeth are spaced at different distances from the transverse end surface Ztl of the slot 14 in the normal position of the pawl seen in FIG. 3.
  • slot 14 is formed by suitable cores, the cores being so designed as to outline the pawl 15 as well as the slot 14.
  • one of the cores adapted to form one side of the locking slot 14 and f part of the outline of the pawl is designated by reference numeral in FIG. 3, and is adapted to move into and out of the mold along a line designated by reference numeral 26.
  • the core has a part 27 that is adapted to form what has heretofore been generally described as the separating slot.
  • This separating slot 28 has what is termed a base surface 29 and a pawl surface 30.
  • the core 25 is also adapted to form the surface 31 of the pawl 15, as is obvious.
  • the teeth of the pawl, and the remaining portion of the locking slot 14, are formed by a core or cores entering the locking slot in an opposed direction to core 25 and in a conventional manner.
  • the pawl 15 will be secured to the base of the head 11, after being formed, by a neck portion 35.
  • This neck portion will be sufficiently narrow, so that the pawl 15 will ex readily.
  • the part 27 of the core 25 is so formed that a part 30a of the pawl surface of the separating slot 28, will be slightly angularly offset. This not only acts to strengthen the core portion 27,
  • FIG. 4 the initial insertion of the strap into locking slot 14 is shown, and it will there be seen that the pawl 15 has flexed away from the transverse end surface 20 of slot 14, this flexing having been made possible by the formation of the neck 35.
  • the strap portion 12 has moved further inwardly of the locking slot 14, and the three teeth 16, 17 and 18 of pawl 15 are in a position to engage three ratchet teeth 13 of the strap.
  • the pawl 15 is maintained in a flexed position by an end portion of one of the ratchet teeth 13 of the strap 12, with teeth 17 and 18 away from the strap teeth.
  • This will generally be the position of the parts when the strap has been pulled about a bundle of conductors or pipes or tubes as presented in FIG. 2 and is held under tension.
  • the strap is cut by a suitable cutting device, as closely to the surface 11a of the head 11 as is possible, and is released.
  • FIG. 6 the strap is shown after it has been cut and released and allowed to move under the stress exerted by the bundle and held thereby.
  • the strap presses against the teeth of the pawl V15 and urges the pawl to a position in which the pawl substantially closes the separating slot 28, bringing the pawl surface 30a against the base surface 29 of the separating slot.
  • all three of the teeth 16, 17 and 18 of the pawl 15 are now firmly engaged with ratchet teeth 13 of the strap 12, 'and that through this engagement, tension on the strap 12 in the direction of the arrow 41 in FIG. 6, has rotated the pawl on its neck into the stop position indicated.
  • Vector arrows V2 are substantially perpendicular to the base surface 29 of the separating slot 28, so that this base surface will act as a stop in a most effective manner. Acually, it would require crushing of the pawl 15 in order to release the strap. Further, the surface 29 will so accept the forces exerted against the pawl, that there will be practically no stress exerted against the neck portion 35.
  • a small lug may be formed on the strap as shown in FIG. 2. This lug is so formed that it will not interfere with the movement of the strap into a correct relationship to the head 11, but will prevent movement in a reverse or incorrect direction. It will 'also be noted that a portion 12a of the strap is bent upwardly as shown in FIG. 2. The purpose of this arrangement is to permit the operator to grasp the strap when it is desired to use it for the bundling operation.
  • a bundling strap of the type comprising a head from which extends longitudinally a strap adapted to be inserted through a transverse locking slot formed in the head and then to be locked against retraction from the locking slot, said transverse locking slot being defined by a transverse end surface and a base, a pawl formed integrally with said base to extend into said locking slot toward said end surface and separated from said base at one side by a narrow separating slot and at the other side by a space so as to leave said pawl secured to the base by a relatively narrow bridge whereby said pawl is free to llex, said narrow separating slot :being formed at an acute angle to said transverse end surface and having a base surface and a pawl surface, a tooth on said pawl, ratchet teeth on said strap, said tooth on said pawl constricting the locking slot so as to require ratcheting flexing of the pawl and widening of said narrow separating slot to allow movement of the end of the strap into the locking slot to engage locking
  • said head and strap are formed as a plastic casting and that said separating slot and one surface of the pawl and a part of said locking slot are formed by a core adapted to be moved into and out of the casting mold angularly in the direction in which said separating slot lies relatively to the transverse end surface of said locking slot.
  • the method of casting the transverse locking slot in the head of a ibundling strap together with a locking pawl integral with the head and positioned in said locking slot comprises utilizing a core for one end of the locking slot that moves in and out of the casting mold at an angle to the normal direction of the slot, and forming on said core an end surface for casting a surface of the pawl, utilizing a relative long flange on said core for forming a separating slot between the pawl and the head whereby the slot is formed in the casting to allow flexing of said pawl while through its angular position limiting the movement of the pawl by a stop surface positioned at an effective angle.
