Definitions

  • top and bottom members are welded so [51] lnt.Cl ..B60r 19/08, that moisture which may bleed from the weld construction B6lf 19/04, B63b 59/02 drains along the inner surface of the bottom member.
  • This invention relates to bumpers for genei'al use in the automotive field. It more particularly relates to bumpers formed of two or more pieces which carry an elastomeric facing strip substantially .the full length of the bumper.
  • the bumper construction of the present invention comprises a top member having a downwardly depending flange, and a bottom member secured to the outer face of said depending flange.
  • the bottom member includes an offset flange to mount a resilient facing strip of elastomeric material which extends substantially the full length of both top and bottom members.
  • the facing strip includes a slit along its length which enables the strip to grip the offset flange. 7
  • FIG. 1 is a schematic plan view of an automotive vehicle having the bumper structure of the present invention secured thereto;
  • FIG. 2 is a front elevational schematic perspective view of the various elements of the bumper separated one from another;
  • FIG. 3 is a schematic sectional view showing the various elements in their assembled relationship.
  • FIG. -1 there is shown a bumper structure embodying the present invention secured to an end of an automotive vehicle 11 by means of a pair of bracket members 12,13.
  • the bumper extends across the end of the vehicle and includes integral opposite wraparound end portions which extend along the sides-of the vehicle.
  • the bumper structure is illustrated as including a top member 15 in the form of a stamping of L-shaped cross section having a horizontal flange l6 and a vertical depending flange 17.
  • the top member may be of suitable metal with an inner surface 18 and outer polished surface 19 such as chrome plate.
  • a lower member 21 having a central generally vertical web 23 is secured to upper member 15 as by weld connections as at 25.
  • the lower member includes an offset flange portion 27 of Z-shape which is integral with the upper margin of the central web 23 and extends outwardly from the weld connection 25.
  • the flange is spaced from the external surface 19 of flange 18 and external surface 28 of web 23.
  • the lower member 21 includes in addition a lower inwardly directed flange 29 which diverges in a curved path from the horizontal flange 16 of upper member 15.
  • the offset flange 27 in addition to providing a strengthening function to the lower stamping, is positioned to support a resilient facing strip 31 substantially along the full length of the bumper.
  • the facing strip may be formed of an elastomeric material which is generally wedge-shaped in cross section and which has good shock absorbing qualities.
  • the interior of the strip defines a grooved or slot 33 which complements in size the longitudinally extending Z-shaped flange 27.
  • the base of the strip is defined by an upper inner surface 34 and a lower inner surface 35 slightly offset an amount corresponding to the thickness of web 23.
  • bracket means 12, 13 similar one to another, are provided to attach thebumper to the chassis of the motor vehicle .11 not shown.
  • Mounting bracket 13 includes a web 37 and an encircling intumed flange 38 which conforms in curvature to the internal surfaces 18 of top member 15 and surface39 of lower member 21 as seen in FIG. 3.
  • the flange 38 of the bracket includes an upper hole 40 aligned with hole 41 in upper member 15, the latter hole being aligned with hole 41 in upper member 15, the latter hole being positioned in a recessed portion as 42.
  • Suitable bolt means 45 are passed through the holes so aligned to secure the upper member to the bracket.
  • the head of the bolt means are received within the recess and thereby enables the surface 34 of the strip to coact the margins of the recess at the outer surface 19.
  • 41 a portion of the flange means 27 is notched as at 47.
  • the flange 38 of mounting bracket 13 includes in addition a lower hole which is aligned with hole 49 in lower bumper member 21 as seen in FIG. 3. Similar bolt means 45 are likewise employed.
  • a channel-shaped bumper for an automobile vehicle comprising in combination:
  • an upper member having a horizontal upper flange and a downwardly directed connection flange extending therefrom,
  • a lower member having a horizontal lower flange and a Z- member extending upwardly therefrom having a connection flange of the upper member and an upper offset vertical flange, said downwardly directed flange being overlappingly secured to the connection flange of the Z-member to provide a channel-shaped bumper structure with an offset vertical flange member extending away from the channel at the connection,
  • Bumper structures as set forth in claim 2 which further includes a bumper support bracket engaging the inner surfaces of the upper and lower members.
