Definitions

  • a spacer member of spirally Wound form is disposed between the laminae of a structural sandwich member in which the laminae are spaced apart by stabilizing structure extending therebetween, the laminae being of relatively high strength in the form of skin elements whereas the stabilizing means joins such laminae and separates the same is of relatively low strength form such as a honeycomb structure but which, when integrated and joined with the skin elements, forms a relatively high strength structural sandwich.
  • a tool for inserting the spacer member into the structure after the structure has been assembled, that is in the sandwich form, and which tool is characterized by the provision of an elongate shaft of a length to completely receive the spacer member thereon for rotation about the lengthwise axis of the shaft, with a head adjacent one end of the shaft rotatable about the lengthwise axis thereof, the head having a clutching portion facing the opposite end portion of the shaft and adapted to receive one end of the spacer member and lock thereto upon rotation of the head in one direction relative to the spacing member.
  • FIG. 1 is an elevational view showing the tool according to the present invention
  • FIG. 2 is an enlarged perspective view partially cutaway showing details of the internal construction at the head end of the tool
  • FIGS. 3 and 4 are views showing the use of the tool.
  • FIG. 5 is a view showing an insert operatively associated with the structural sandwich.
  • a structural sandwich is indicated generally by the reference character which may be seen to consist of an outer skin element 12, an inner skin element 14 and an intervening core 16.
  • the core 16 serves to rigidly interconnect the two skin elements 12 and 14 and it will be appreciated that the nature of the core material 16 is generally of honeycomb form constructed of extremely thin or film-like material.
  • FIG. 5 cumulatively provides a structural sandwich of extreme rigidity in comparison to the weight thereof, it will also be appreciated that due to the nature of the core material 16, which contributes materially to the lightweight construction of the sandwich, the sandwich is not well adapted to resist crushing forces which are highly localized in their application.
  • a reinforcing insert indicated generally by the reference character 18 is utilized between the skin elements 12 and 14 in an area thereof in which localized crushing action would occur as for ex- 3,178,809 Patented Apr. 20, 1965 ample when a fastener element is adapted to be passed through the sandwich for the purpose of securing a bracket structure or the like to either face of the sandwich.
  • the insert 18 is not formed originally with a sandwich member but is positioned in the manner shown in FIG. 5 after the sandwich has been fabricated and after it has been determined whereat an aforementioned fastening element is desired to be placed.
  • the first step is to drill completely through the structural sandwich 10 as indicated by reference characters 20 and 22 and, thereafter, a suitable tool (not shown) is used to clean out and remove the core material 16 immediately surrounding the openings 20 and 22 as is indicated by the reference character 24, so that clearance is provided for the insertion of the insert.
  • the insert is of helical form as shown and when disposed between the two laminations or skins 12 and 14, the coils of the insert are completely closed so that it has a solid length which is substantially equal to the spacing between the inner faces of the skin elements 12 and 14.
  • a fastener such as a bolt and nut assembly
  • the localized crushing force exerted by the interengagement between the bolt and its associated nut will not locally crush the core 16 and destroy the effectiveness of the sandwich assembly 10.
  • the present tool as is illustrated in FIGS. 1 and 2 is utilized for the purpose of positioning the insert 18 in a manner illustrated in FIG. 5.
  • the tool comprises an elongate shank having a bulbous end portion 32 and being provided at its upper end with a head assembly indicated generally by the reference character 34.
  • the shank portion 30 is of a length exceeding that of the spacer member 18 and is also of a diameter less than the difference between the diameter of the openings 20 and 22 and the Width or diameter of the spacer wire.
  • the diameter of the bulbous portion 32 is less than the diameter of the holes 20 and 22 but is greater than the difference between the diameter of such openings and the width of the spacer wire.
  • the purposes for these constructions will be hereinafter set forth.
  • the head assembly 34 is rotatably mounted on the shank 30 and this is clearly illustrated in FIG. 2 of the drawing.
  • the body 36 of the head assembly 34 is provided with an axial bore 38 which receives a journal portion 40 of the shank 30 and which journal portion 40 is bounded at its opposite ends by shoulder portions 42 and 44 so as to limit axial displacement between the shank 30 and the head assembly 34.
  • the head assembly 34 at that end thereof facing the bulbous portion 32 is provided with a counterbore which is internally threaded or grooved as indicated by reference character 46 and at the inner end of this counterbore is a downwardly facing shoulder surface 48 against which the upper end of the insert member 18 is adapted to bottom, the grooved portion 46 being of a direction and construction as to threadedly receive the upper end of the insert 18 as will be readily apparent.
  • the insert When it is desired to place an insert 18 in association with the structural sandwich 10, subsequent to the provision of the openings 20 and the enlarged portion 24, the insert is engaged on the shank 30 and screwed into the counterbore of the head assembly 34 until the upper end thereof bottoms against the aforesaid surface 48. At this 3" 7 point, the insert will be. rigid with the head assembly; The shank 30 is then inserted through the openings 20 and 22 as is illustrated in FIG. 3 and the lower end of the insert engaged so that it is-disposed through the opening 20 and through the outer skin element 12. With the. parts in this position, the head assembly 34 is manually rotated so as to feed a few coils of the insert assembly 18 to the underside of the outer skin member-12.
  • the head assembly 34 is rotated in the opposite direction'to unclutch the head assembly from the upper end of the insert 18, the shank assembly is withdrawn upwardly so that the bulbous lowerend portion 32 projects within the confines of the lower opening.
  • shank 30 must be of a diameter which is less than the difference between the tions as illustrated'and described may be made without departing from the spirit of the invention or the scope of the following claims Iclaim: r 1. A tool for inserting a spirally wound wire spacer member through an opening into a space between spaced apart laminae of a pre-assembled structural member,
  • tool comprises an-elongated shaft, and a handle frotatably carried by said shaft adjacentone end thereof for rotation about substantially the axis thereof, said handle having a clutching portion facing the opposite end of said shaft for receiving-one end of a spacer member and clutching therewith upon rotation relative thereto ,in one direction, the opposite end of said shaft being of bulbous form.
  • Atool for inserting a spirally wound spacer member between spaced apart larninae'of a structural memher through an opening therethrough which comprises an elongate shaft havinganenlarged bulbous end portion,.
