Definitions

  • This invention relates to luggage cases, and more specifically relates to upright luggage cases with wheel designs allowing for more maneuverability and stability.
  • Luggage cases are well-known in the art.
  • a popular luggage case design is shaped generally like a rectangular box having four sides, a top, and a bottom.
  • two of the four sides i.e., front and back sides
  • the width of the wider sides define a wide dimension
  • the width of the narrower sides define a narrow dimension.
  • wheels have been added to the bottoms of luggage cases to allow a user to move a heavy luggage case more easily from one location to another without having to carry it. As wheeled luggage cases have become more popular, further attempts have been made to make the luggage cases more maneuverable.
  • the design shown in the '739 patent allows the luggage case to be tipped and pulled in a direction substantially parallel to its wide dimension while supported by the two wheels, which makes it easier to maneuver the luggage case down narrow passages or aisles.
  • the luggage case disclosed in the '739 patent does not allow it to also be pulled in a direction substantially parallel to its narrow dimension.
  • U.S. Pat. No. 5,197,578 ('578).
  • the luggage case shown in the '578 patent has four wheels on its bottom surface. Three of the four wheels are caster wheels that can turn 360°.
  • the fourth wheel is a fixed axis wheel with its center fixed on an axis substantially parallel to the wide dimension of the luggage case.
  • the design shown in the '578 patent allows the luggage case to be tipped and pulled in a direction substantially parallel to its narrow dimension while being supported on two caster wheels.
  • the luggage case also rolls in a direction substantially parallel to its wider dimension when supported on all four wheels, allowing it to more easily be rolled down narrow passages or aisles.
  • U.S. Pat. No. 5,564,538 discloses a luggage case that can be tipped and rolled in a direction substantially parallel to its wider dimension and in a direction substantially parallel to its narrow dimension.
  • the '538 patent discloses a luggage case with an extendable handle, front and back sides, narrower left and right sides, a top, a bottom, and six wheels. A first pair of wheels are mounted on a first edge defined by the intersection of a back side and the bottom of the luggage case. Therefore, the luggage case can be tipped and pulled in a rearward direction while being supported on the first pair of wheels.
  • a second pair of wheels are mounted on a second edge defined by the intersection of a right side and the bottom of the luggage case.
  • a third pair of wheels are also mounted on a third edge defined by the intersection of a left side and the bottom of the luggage case. Therefore, the luggage case can also be tipped and pulled in either direction substantially parallel to its wide dimension while supported on either the second or third pair of wheels.
  • the luggage case disclosed in the '538 patent When the luggage case disclosed in the '538 patent is tipped and pulled while being supported by either the second or third pair of wheels, it may be susceptible to tipping to one side or the other depending upon the location of the center of gravity of the luggage case and the relative placement of the handle.
  • the center of gravity is located in the geometric center of the luggage case, but the location may change depending upon how a user stores goods in the luggage case. For example, a user may store heavier items toward the front of the luggage case, which may cause the center of gravity to shift toward the front of the luggage case, and cause it to be somewhat unstable when rolling sideways.
  • one embodiment disclosed in the '538 patent places an extendable handle in the middle of the luggage case.
  • U.S. Pat. No. 5,890,570 patent discloses a second embodiment with a handle mechanism mounted adjacent to the rear side of the luggage case.
  • the handle mechanism disclosed in the second embodiment also has a rotatable handle portion.
  • the handle portion 90° When pulling the luggage in a direction substantially parallel to its wide dimension (i.e., sideways), the user rotates the handle portion 90° such that it is centered over the top of the luggage case to help keep it balanced.
  • the rotatable handle includes additional moving parts that may be susceptible to breaking. Additionally, when the handle portion is rotated over of the top of the luggage case, it may interfere with a user attempting to gain access to the inside of the luggage case from the top.
  • the instant invention provides a wheeled upright luggage case with an extendable handle mechanism mounted adjacent to a broad side wall structure of the luggage case with a wheel placement and configuration such that the luggage case maintains it balance when tipped and pulled in a direction substantially parallel to its wide dimension even if the center of gravity of the luggage case has shifted.
  • a wheeled luggage case includes a main body having a top surface, a bottom surface, a front wall, a rear wall, a first side wall, and a second side wall; an extendable handle mounted adjacent to the rear wall; a first wheel and a second wheel rotatably and operably connected with a rear edge; the rear edge defined by an intersection of the rear wall and the bottom surface; a first rearward side wheel and a first frontward side wheel rotatably and operably connected with a first side edge, the first side edge defined by an intersection of the first side wall and the bottom surface; and wherein a first distance from the first side edge to a first contact point of the first frontward side wheel is greater than a second distance from the first side edge to a second contact point of the first rearward side wheel.
  • a luggage case in another scenario of the present invention, includes a main body having a top surface, a bottom surface, a front wall, a rear wall, a first side wall, and a second side wall; an extendable handle mounted adjacent to the rear wall; wherein the first wall and the second wall separate the front wall from the rear wall. Further wherein a first width of the first wall and the second wall define a narrow dimension, and a second width of the front wall and the rear wall define a wide dimension. Also including a means for rolling the luggage case in a first direction substantially parallel to the narrow dimension; a means for rolling the luggage case in a second direction substantially parallel to the wide dimension; and a means for tilting the luggage case toward the rear wall when rolling in the second direction.
  • a wheeled luggage case includes a main body having a top surface, a bottom surface, a front wall, a rear wall, a first side wall, and a second side wall, wherein the front wall and the rear wall are wider than the first side wall and the second side wall; an extendable handle mounted adjacent to the rear wall; at least one rear wheel rotatably and operably connected with a rear edge, the rear edge defined by an intersection of the rear wall and the bottom surface; at least one side wheel rotatably and operably connected with a first side edge, the first side edge defined by an intersection of the first side wall and the bottom surface; and wherein the wheeled luggage case tilts toward the rear wall when supported by the at least one side wheel.

  • the user may then pull on the handle 48 to roll the luggage case 30 on the side wheels 90 in a direction substantially parallel to its wide dimension, D W .
  • a center of gravity, C G , of the luggage case 30 typically tends to be located somewhere in a geometric center of the luggage case.
  • the center of gravity, C G should lie between the rear wheels 84 or the side wheels 90 whether the case is standing erect, being pulled while supported on its rear wheels 84 , or being pulled while being supported on its side wheels 90 .
  • the center of gravity, C G may shift toward the front wall 34 or rear wall 36 of the luggage case 30 .
  • the center of gravity, C G may shift toward the front wall 34 of the luggage case 30 . Shifting the center of gravity, C G , too far toward the front wall 34 of the luggage case 30 may cause the luggage case tip over when at rest on the support surface 130 .
  • This problem may be overcome by placing glides 120 on the bottom surface 42 of the luggage case with bottom supports 122 extending down from the bottom surface 42 of the luggage case far enough such that the case tilts toward the back wall 36 when at rest on the support surfaces 130 .
  • Tilting the luggage case 30 toward the back wall 36 tends to move the center of gravity, C G , away from the front wall 34 and helps to prevent to luggage case 30 from tipping over frontwards when a user, for instance, packs extra goods in front pockets ( 68 , 70 ) attached to the front wall 34 .
  • Packing the luggage case 30 in such a manner that the center of gravity, C G , shifts toward the front wall 34 of the luggage case 30 may also present a problem with stability when the luggage case 30 is rolled in a direction parallel to its wide dimension, D W (i.e., supported on side wheels). This is because when the user is rolling the luggage case 30 in a direction parallel to its wide dimension, D W , the user's hand is not in a proper position on the handle 48 to effectively counteract, support or resist tipping of the luggage case toward the front wall 34 . This is because the handle extends from the rear wall of the luggage case, and the user's leverage, and thus control, of a frontward tipping luggage case is reduced.
  • FIG. 12 shows a front fragmentary view of the luggage case 30
  • FIG. 13 shows a rear fragmentary view of the luggage case 30 while supported on the right side wheels 90 .
  • a first point of contact 132 is defined where the frontward right wheel 96 contacts the support surface 130 .

  • the distance between the right edge 82 and the first point of contact 132 is defined by a dimension, D F .
  • a second point of contact 134 is defined where the rearward right wheel contacts the support surface.
  • a portion of the right wheel housing 100 and rear wall 36 of the luggage case 30 is cut out of the drawing in order to show the right edge 82 of the luggage case located directly above the second point of contact 134 .
  • the distance between the right edge 82 and the second point of contact 134 is defined by a dimension, D R .
  • FIG. 15 shows a right side view of the luggage case 30 supported by two side wheels 90 conforming to the present invention.
  • a support triangle 136 is defined by the first 132 and second 134 contact points and the handle 48 supported by the user.
  • the luggage case 30 is more stable when the center of gravity, C G , is located inside the support triangle 136 .
  • Tilting the luggage case 30 toward the rear wall 36 tends to more dependably place the center of gravity, C G , between the contact points ( 132 , 134 ) and more importantly, within the support triangle 136 . This is true even though a substantial portion of the luggage case, in particular, virtually the entire front wall 34 with its front pockets ( 68 , 70 ), and much of the volume of the main packing compartment 64 toward the upper surface of the luggage case falls outside of the support triangle 136 .
  • the luggage case 30 tilts toward the rear wall 36 , the luggage case becomes more stable and resistive to tipping as the luggage case is rolled in a direction parallel to its wide dimension, D W (i.e., supported on side wheels) and when it has been packed such that the center of gravity, C G , shifts toward the front wall 34 .
  • D W i.e., supported on side wheels
  • the wheels 74 and associated geometry may be configured in various ways to achieve the benefits of the present invention.
  • all of the side wheels 90 have the same diameter.
  • the respective mount for the side wheels 90 mounted on the glides 120 is spaced farther from the side edges ( 80 , 82 ) of the luggage case 30 than the side wheels 90 mounted on the wheel housings 100 .
  • dimensions D F and D R may have varying combinations of distances.
  • D F is 1 ⁇ fraction (11/16) ⁇ inches and D R is 13 ⁇ 8 inches. This geometry results in the luggage case 30 tilting toward the rear wall 36 at about 7° from vertical.
  • the present invention can be applied to luggage having various geometric shapes and internal or external features, and is not limited to the luggage case disclosed herein.
  • Other embodiments of the present invention may utilize various configurations and combinations of wheel sizes, spacing and/or glide support spacing to achieve the desired orientation of the luggage case when at rest on a support surface to prevent tipping.
  • the tendency to tip can be overcome by configuring the wheel spacing, sizes, and/or glide supports such that the luggage case leans in a direction opposite of the tipping direction.
  • wheel sizing and/or spacing in various configurations or combinations may be used to overcome a luggage case's tendency to tip in one direction by causing the luggage to lean in a direction opposite of the tipping direction when the luggage is rolling.
  • wheel spacing and/or sizes can be configured so that a first bottom edge of the luggage case is elevated higher from the support surface than a second bottom edge opposite the first bottom edge when the luggage case is being wheeled. This configuration causes the luggage case to lean in a direction away from the first bottom edge. Therefore, the design resulting in a tilt of the luggage case resists tipping when being wheeled where the center of gravity of the luggage case is located in a direction closer to a side adjacent the first bottom edge.
