The present invention relates to a luggage article, and in particular to wheeled luggage cases and more specifically to the wheel arrangements for such wheeled luggage cases.
Luggage items and in particular luggage cases (suitcases) now conventionally include wheels and tow handle arrangements to allow them to be wheeled and more easily moved by a user. Originally a pair of fixed axis wheel were provided at one end and on the sides of a case to allow the case to be wheeled on one end in a length wise manner (long side of the case generally horizontal). An example of such an arrangement is the Samsonite Oyster suitcase. This arrangement with a pair of wheels has evolved to provide additional fixed axis wheel at both ends of the case, and also to use wheels that are mounted to also rotate about a vertical axis (so called spinner wheels). An example of such a configuration with fixed and spinner type wheels is shown in EP 0106906. More recently there has been a change to provide cases that are arranged to be wheeled in a more vertical orientation (i.e. with their longest sides/dimension) vertical, and an increasing trend to provide four spinner type wheels on the bottom end. Such multiple spinner wheels allow better maneuverability of the case and easier user handling. Such an arrangement is now the standard default configuration.
A problem with wheeled cases is that in order to minimise the overall dimensions of the case which include the wheels, it is desirable to minimise the size of the wheels. Small wheels however are less able to cope and operate on rough surfaces. Spinner wheels in particular take up a lot of space with the actual diameter of the wheel having to be reduced to minimise overall space. A further general problem is to provide a suitcase that can more easily cope with stairs, with in general cases having to be manually carried up and down stairs.
It is therefore desirable to provide an improved luggage article, and more specifically an improved wheel arrangement on a luggage case that addresses the above described problems and/or which more generally offers improvements or an alternative to existing arrangements.
According to the present invention there is therefore provided a luggage article as described in the accompanying claims.
In an embodiment of the invention, a luggage article may include opposing front and back walls, opposing side walls, opposing end walls, and a plurality of wheels to allow the luggage article to be wheeled. The opposing front and back walls form major faces of the luggage article and define a height and a width of the luggage article. The opposing sidewalls form side faces of the luggage article extending between the opposing front and back walls and defining a depth of the luggage article. The opposing end walls form top and bottom end faces of the luggage article wherein the front, back, side, top and end walls together define an outer structure and an enclosed space of the luggage article. The height dimension of the luggage article is greater than the width dimension which is greater than the depth dimension. The plurality of wheels comprise a pair of fixed axis wheels having a common fixed rotational axis and being axially spaced apart with the common fixed rotational axis substantially perpendicular to the major faces and located towards a bottom corner of the major faces, and at least one spinner wheel assembly that is mounted to the luggage article to rotate at least one wheel about at least two orthogonal axes and that is located on the bottom end face of the luggage spaced a distance along the width from the common fixed rotational axis of fixed wheels.
Such a luggage article can be wheeled over and cope better with rough terrain than a more conventional luggage article, which still being relatively maneuverable, and offers an improvement and alternative to conventional luggage articles.
The fixed axis wheels preferably have a peripheral rim that projects beyond the bottom end and beyond an adjacent side face of the luggage article. Such an arrangement allows the luggage article to be more easily dragged and wheeled up steps or stairs.
The fixed axis wheels may have a diameter that is at least 25%, and preferably at least 50%, of the width of the luggage article. Such wheels are much larger than conventional wheels and are better able to be wheeled over rough terrain.
The luggage article preferably comprises an opening line formed in said side faces and end walls along which said luggage article separates into a lid section and base section to allow access to the enclosed space within the luggage article. The opening line may be parallel to and closer to one of the major faces than to the other opposing major face. Alternatively the opening line may be more centrally located.
The luggage article may comprise a single spinner wheel assembly. Alternatively there may be a pair of spinner wheel assemblies located spaced apart across the depth of the bottom end of the luggage article.
Preferably the luggage article includes a tow handle extending above the top end of the luggage article. The tow handle preferably retractably extends above the top end of the luggage article. The tow handle may be located substantially centrally between front and back major faces. Alternatively the tow handle is located substantially adjacent to the front or back wall of the luggage article, and furthermore may be located substantially centrally across the width of one of the major faces of the luggage article. The tow handle preferably comprises a grip portion that extends substantially across the full width of the top end of the luggage article.
The luggage article is preferably a hardside luggage case wherein the front, back and side walls and top and bottom ends are all rigid and self-supporting.
The present invention will now be described by way of example only with reference to the following figures in which:
Referring to
The case 100 is of a type generally known as a hard side case in which the outer structure and walls 102, 104, 106, 108, 110, 112 of the case 100 are relatively rigid. The outer structure of the luggage case 100 may be, for example, plastic (e.g., composite plastic, acrylonitrile butadiene styrene, polymer, thermoplastic, and so forth) and may be manufactured by extrusion, mold forming, blow molding, and so forth.
The case 100 is split along a generally vertical plane and opening line 114 parallel to the major faces 101, 103 into a lid section 116, which includes the front wall 102, and a base section 118, which includes the rear wall 104. In this embodiment, the opening line 114 is located parallel to, and much closer or adjacent to, the front face 101 such that the base section 118 comprises the rear wall 104 and a majority of the side and top and bottom walls 106, 108, 110, 112, and the lid section 114 comprises substantially just the front wall 102. In other embodiments, the opening line may be much more centrally located mid-way between the front and rear faces 101, 103 such that the lid and base sections are more similarly sized.
The lid section 116 is connected to the base section 118 along on a side via a hinge 120 in a conventional manner, and the case 100 is opened at the opening line 114 to access the internal volume. The hinge 120 may be formed of a zipper and a fabric strip, a piano hinge, discrete hinges spaced apart, or an articulating joint. The piano hinge, the discrete hinges, or the articulating joint may be made from metal, plastic, any other suitable material, or any combination thereof. The hinge 120 may be stitched to the lid 116 and also to the base 118, or may be coupled in another suitable manner. In some examples, the luggage case 100 may be hinged along the left or the right side wall 106, 108, whereas in other examples, the luggage case 100 may be hinged along the bottom 110, or along any other face of the luggage case 100. A zipper 122 along a periphery of the opening line 114 or other conventional closure arrangement, for example clamp locks, secures the lid section 116 to the base section 118 to close the case 100.
A pair of fixed axis wheels 124 are mounted respectively on the opposing front and rear walls 102, 104 of the case 100, axially spaced apart by substantially the depth D of the case 100. The fixed axis wheels 124 rotate about a common fixed axis 126, which is generally perpendicular to the front and rear faces 101, 103 and generally horizontal. Each of the fixed axis wheels 124 is located at a bottom end corner of the case 100. In other words, each fixed axis wheel 124 is located near the bottom end 110 and one side wall 108 of the case 100. A peripheral rim 128 and edge of the fixed axis wheels 124 project a distance d1 beyond the bottom end wall and a distance d2 beyond a side wall 108 of the case 100 to allow the case to be supported on the ground on the fixed axis wheels 124. The fixed axis wheels 124 are relatively large, as compared to conventional suitcase wheels, and may preferably have a diameter d3 of at least 25% of the width W of the major face 101, 103 of the case 100 to which they are mounted and more preferably of at least 50% of the width W of the case 100. Each fixed axis wheel 124 may preferably be located in a recess 130 formed within either the front or rear face 101, 103 of the case such that an axial end face 132 of each fixed axis wheel 124 is substantially flush with one of the front and rear major faces 101, 103.
A spinner wheel assembly 134 is mounted from the bottom end wall 110 of the case 100. The spinner wheel assembly 134 may be spaced from the fixed axis wheels 124 a distance along the width W of the case 100 and may be preferably located at an end of the bottom end wall 110 of the case 100 that is opposite the end of the bottom end wall 110 that is proximate to the fixed axis wheels 124. In this embodiment, a single spinner wheel assembly 134 is located centrally across the depth D of the case 100 mid-way between the front and rear walls 102,104. In other embodiments, however, in particular if the case 100 has a more central opening line 114, a pair of spinner wheel assemblies may be provided spaced across the bottom end wall and spaced across the depth of the case. Such a pair of spinner wheels are more stable but increase the weight of the case 110 and the number of components and make the case 100 less maneuverable. The spinner wheel assembly 134 is of a conventional construction and comprises, in this case, a pair of wheels 136, 138 (although only one wheel may be provided in other embodiments). The pair of wheels 136, 138 are rotationally mounted to a spinner fork bracket 140 to rotate about a wheel axis 142, which is generally horizontal and parallel to the bottom wall 110 of the case 100, and the fork bracket 140 is rotationally mounted to the bottom end wall 110 of the case 100 to rotate about a generally vertical spinner axis 146 perpendicular to the bottom end wall 110 of the case 100. Such an arrangement allows the spinner wheels 136, 138 to rotate about two orthogonal axes 142, 146: the horizontal wheel axis 142 and the vertical spinner axis 146. The spinner wheel assembly 134 projects beyond the bottom wall 110 of the case 100 such that a peripheral rim 148 of the spinner wheels 136, 138 projects beyond the bottom end wall 110 by a distance d4. This distance d4 is preferably the same distance d1 as the peripheral rim and edge 128 of the fixed axis wheel 124 project beyond the bottom end wall 110. This, in turn, allows the case 100 to be supported on the ground on the fixed axis and spinner wheels 124, 134 with the case 100 in a vertical upright orientation with the side and front and rear walls 102, 104, 106, 108 vertical and the top and bottom walls 110, 112 generally horizontal with the ground and further allows the case 100 to be wheeled along the ground on the fixed axis 124 and spinner wheel assemblies 134 in a stable upright orientation as shown in
The luggage case 100 also includes a telescoping tow handle 150, which can be extended above the top wall 112 of the case 100 to an extended position at a convenient height for a user to hold. The telescoping tow handle 150 may be used to pull, direct, and wheel the case 100. In particular in this case, the tow handle 150 is oriented to have a grip portion 152 that is parallel to the rear face 103 of the case 100 with a user using the handle 150 to guide the case 100 in a forward side on direction shown by arrow A. The tow handle 150 in this embodiment telescopically extends from the case 100 adjacent to, and in the center of, the rear face 103 of the case 100 and comprises two parallel tubes 154, 156 interconnected at one top end by the grip portion 152. In other embodiments, for example as shown
In use, the case 100 can be wheeled in the upright orientation as shown in
While these embodiments have been described in relation to a hard side suitcases, and these are the preferred embodiments of the invention, the invention may be incorporated into a soft side case in which the walls and outer housing structure of the case are made of a textile and/or more flexible material and the case includes a frame to support the wheels and other components. In addition the concept of providing relatively large fixed axis wheel in combination with a spinner type wheels on a bottom end of the case which is shorter than the height of the case, and which is to be wheeled in an upright orientation side-on, can also be applied to other luggage articles for example a wheeled duffle type bag.
