Definitions

  • This invention is concerned more particularly with luggage of the type wherein the wheels permitting the easy rolling of the luggage on the ground or floor are adapted, when the luggage is to be carried by hand, to be folded and collapsed against the bottom-forming major surface of the luggage by causing the side or longitudinal members of a handbar to slide in rotatably mounted sleeves.
  • This sliding movement causes the sleeves to pivot through substantially 90; in this structure, each rotary sleeve carries at one end a pair of flanges acting as a shoulder for supporting the shaft of the relevant wheel.
  • the wheels lie against the aforesaid bottom-forming major surface of the luggage without projecting appreciably from this surface, with their wheel shafts perpendicular to the surface; on the other hand, in the rolling position the wheels swung to their operative positions, i.e., with their axes parallel or substantially parallel to the major surface.
  • each wheel supporting socket In luggage thus equipped the pivoting movement of each wheel supporting socket is limited, in the operative or rolling position, by a simple stop member so that when a transverse force is applied to the wheels or to one of the wheels in the direction opposite to said stop member, for example when clearing a pavement or sidewalk step, this force is transmitted to the mechanism which caused the wheels to move to their operative position, thus tending to fold the wheels and producing a certain wheel wobble and undesired strain in the mechanism controlling the wheel position.
  • the invention avoids this inconvenience by providing means for affording a certain freedom of movement of each wheel-supporting sleeve in the axial direction and by on the other forming in each sleeve a notch adapted, at the end of the movement of the wheels towards their operative positions to act as a limit stop and as a positive means for coupling the sleeves to fixed bearings guiding said sleeves, this coupling taking place automatically by snap action due to the weight of the luggage and causing the wheels to be positively held in the proper orientation.
  • FIG. 1 is a perspective view of a luggage in the handcarried position
  • FIG. 2 is a perspective view showing the same article ofluggage after the displacement of the wheels to their rolling position
  • FIG. 3 is another perspective view showing on a larger scale the same article of luggage being used on the floor;
  • FIG. 4 is a front-elevational view of one of the fixed notched members acting as a bearing for the respective rotary tubular sleeve;
  • FIG. 5 illustrates the same fixed notched member in side-elevational view
  • FIG. 6 illustrates in a front elevational view the rotary sleeve with its wheel-supporting arm
  • FIG. 7 shows the same sleeve in a side-elevational view
  • FIG. 8 is a fragmentary detail view showing the front surface of the luggage with the wheels retracted therein;
  • FIGS. 9 and 10 are views similar to FIG. 8 but showing the mechanism in an intermediate position and in the fully operative position, respectively;
  • FIGS. 11 and 12 are elevational views showing the device in the positions of FIGS. 8 and 10, respectively.
  • FIG. 13 illustrates the use of the device of this invention in the ease-of a canteen or officers chest or trunk.
  • the article of luggage 1 is of rectangular parallelipipedal shape and comprises, on its major surface constituting the bottom thereof (opposite to the cover), a pair of spaced parallel tubular rotary sleeves 2 in which the side members or arms 3 of a handlebar 4 are telescoped.
  • a socket 5 is secured for example by welding or brazing to the end of each sleeve 2.
  • the throughgoing axial hole of this socket 5 is of polygonal section, for example square section, and the side members 3 have the same cross-sectional contour with a play sufficient to permit their sliding movement therein.
  • the aforesaid arms 3 have a helical configuration as shown at 6, whereby the axial sliding movement of the members 3 in the sockets 5 causes the sleeves 2 to rotate. Stop members 7 prevent the side members 3 from being totally withdrawn from the sockets 5 in which they are slidably mounted.
  • each sleeve 2 extends through a fixed bearing 8 acting as guide means and these bearings 8 are secured to the front surface of the luggage 1 by means of a cross member 9 of suitable crosssectional contour.
  • each bearing 8 is notched and comprises a pair of semi-circular faces 11, 12 disposed at different levels, as seen in the drawing (FIGS. 4 and 5). Face 11 lies at to a lower level than face 12 and terminates with a vertical face 13 extending to the bottom of a notch 14 connected through a cam face or ramp 15 to the other semi-circular face 12.
  • This contour of the fixed bearing 8 registers with a matching contour formed on a portion 16 of greater diameter of the sleeve 2 which is rigid with a clamp-like collar portion 17 formed with integral radial flanges 18 receiving in their outer ends the shaft 19 of a wheel or roller 20.
  • the thicker portion 16 of sleeve 2 has an upper contour constituting the counterpart of the notched contour of the respective bearing 8 in that it comprises a pair of semi-circular faces 21, 22 interconnected by a vertical face 23 and an inclined face 24, as shown.
  • the bottom surface of the luggage further comprises across each wheel 20 a hollow or dished depression 25 adapted to accomodate the corresponding wheel in the retracted or collapsed position thereof, to avoid any undesired profection of the wheels from this surface.
  • the sleeves 2 are also sunk for the same reason in grooves 26 formed in said bottom surface of the luggage.
  • each thicker portion 16 of sleeves 2 engages or bears against the registering end face 12 of the corresponding fixed bearing 8, and the lower ends of said sleeves 2 bear against the lower ends of the corresponding grooves 26.
  • the sleeves 2 can move freely downward and take up the play x, so that the inclined ramps 24 are released from their notches l4 and the helical configuration of arms 3 causes these sleeves to be rotated in the opposite direction to re-insert the wheels into their hollows 25 and cause them to engage the bottom surface of the luggage.
  • FIG. 13 illustrates the application of the present invention to a trunk or canteen 29, wherein the sleeves 2 are mounted under a frame structure 30 so that the hollows 25 can be dispensed with, the wheels 20 being retracted inside this frame structure, as shown.
  • a wheel-supported carrier comprising:
  • a pair of bushings mounted on said base parallel to and adjacent to each said longitudinal edge a pair of wheels each connected to a cylindrical rotatable sleeves and mounted on said base about respective pivotal axes generally parallel to said longitudinal edges whereby the axes of said wheels can assume a retracted position perpendicular to said base and an operative position generally parallel thereto upon pivotal movement of said sleeves about their relative axes;
  • each sleeve having an end portion of larger diameter than the remainder of said sleeve each bushing and the respective end portion of said sleeve having camming engagement confronting faces, one of the confronting faces being formed with a recess defined between a steep fiank and an inclined flank and the other confronting face being formed with a projection generally complementary to said recess and formed between a steep flank and an inclined flank whereby the steep flanks of the confronting faces abut one another in said operative position to limit further rotation of each sleeve in the sense tending to swing the respective wheels of its retracted position while the inclined flanks of the confronting faces mutually engage to prevent opposite rotation of the respective sleeve in the absence of relative axial displacement of each bushing and the respective sleeve; and
  • each handlebar member and sleeve for operatively coupling same to rotate said sleeves and the larger end portion connected thereto to swing the respective wheels out of their retracted positions and into their operative positions upon axial telescoping withdrawal of the handlebar members from the respective sleeves;
