Description

BACKGROUND OF THE INVENTION

The typical time pressures encountered by a traveller meeting airplane or train schedules are often complicated by large, cumbersome and/or heavy suitcases or articles of luggage. In order to avoid the direct carrying of such luggage, individual articles of luggage are characteristically rendered movable along an underlying ground surface by the provision of a number of wheels or casters attached to the bottom surface of the luggage such that the wheels may freely spin in a direction of travel and, in some cases, pivot about an axis defined substantially perpendicular to the bottom surface. Each piece of movable luggage also classically possesses a strap or other handle positioned on the top surface or along a side or front face thereof for pulling the luggage along the ground surface and for carrying the luggage from place to place.

However, such luggage still has a lot of drawbacks and is unsatisfactory in use. Therefore, it is an object of the present invention to provide an improved wheeled luggage which is sturdy in construction and convenient in use.

SUMMARY OF THE INVENTION

This invention relates to an improved wheeled luggage.

It is the primary object of the present invention to provide a wheeled luggage which is sturdy in construction.

It is another object of the present invention to provide a wheeled luggage the handle of which can be kept at a fixed position.

It is still another object of the present invention to provide a wheeled luggage which can be conveniently connected with an additional luggage.

It is still another object of the present invention to provide a wheeled luggage which is low in cost.

It is a further object of the present invention to provide a wheeled luggage which is simple in structure.

The invention accordingly consists of features of constructions and method, combination of elements, arrangement of parts and steps of the method which will be exemplified in the constructions and method hereinafter disclosed, the scope of the application of which will be indicated in the claim following.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

For purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe the same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alternations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.

With reference to the drawings and in particular to FIG. 1 thereof, the wheeled luggage according to the present invention comprises a body portion 1 with two wheels 21 at a lower edge of the body portion 1. On the bottom of the body portion 1 there is mounted a L-shaped member 3 which is formed with a lug 31 at both ends thereof. An axle 32 is inserted through the two lugs 31 of the L-shaped member 3. On the rear side 10 of the body portion there are two tubular members 41 (only one of them is shown in FIG. 1) for receiving two pull rods of the handle 42. The tubular members 41 are fixedly secured on the L-shaped member 3 at the lower end, and are connected with a sleeve 5 at the upper end. A fastening strip 62 is fixedly secured on the top of the body portion 1 at one end and is provided with a knob 62 at the other end. The knob 62 is formed with an upper groove 6211 and a lower groove 6212 disposed under the upper groove 6211 and is designed to engage a strap 63. The strap 63 is provided at one end with a buckle 632 at both ends.

Looking now at FIG. 2, the body portion 1 is formed with a recess 11 at both corners in alignment with the axle 32. A wheel protector 22 is mounted on the axle 32, with its hole 225 receiving the axle 32. Further, the wheel protector 22 has a contour adapted to the body portion 1 and has a first protecting side 221 and a second protecting side 222 on which there are a plurality of holes 223. The body portion 1 is also provided with corresponding holes 13 in alignment with the holes 223 so that the wheel protector 22 can be firmly mounted on the body portion 1 by rivets 14. In addition, the wheel protector 22 is formed with a recess 224 so that the wheel 21 can be disposed in the recess 224 and pivotally connected with the axle 32 by engaging a screw 211 with the threaded end 321 of the axle 32.

As illustrated in FIGS. 3, 4A, 4B and 4C, the sleeve 5 is composed of a plug 51 and an annular member 52. The plug 51 has a cylindrical portion 511 enclosed with a plurality of clamping members 512 having a hook portion 513 at the lower end. The distance between the inner side of the clamping member 512 and the outer side of the cylindrical portion 511 is slightly smaller than the wall thickness of the tubular member 41. The inner diameter of the annular member 52 is just equal to the outer diameter of the cylinder formed by the clamping members 512. Further, the annular member 52 is slightly shorter than the clamping members 512 in height. Further, the annular member 52 has an inclined surface 521 at its inner edge. The engagement between the sleeve 5 and the tubular member 41 is shown in FIG. 4B. As may be seen, the plug 51 is first mounted on the top side of the body portion 1 and then the annular member 52 is put on to the plug 51 and kept in place by the hook portions 513 of the clamping members 512. Thereafter, the tubular member 41 is inserted between the cylindrical portion 511 and the clamping members 512 of the plug 51. In the meantime, the clamping members 512 are forced to go outward thereby causing the hook portions 513 to push the annular member 52 to go upward and therefore strengthening the engagement between the sleeve 5 and the body portion 1.

The pull rod of the handle 42 is first inserted in the tubular member 41 and then a guide member 43 is threadedly engaged with the lower end of the pull rod 42. The outer diameter of the guide member 43 is slightly larger than the inner diameter of the tubular member 41. In addition, the guide member 43 is formed with a slit 431 so as to make it easier to insert the guide member 43 into the tubular member 41. Further, a partition 15 (see FIG. 1) is arranged in front of the tubular members 41 so that the other side of the partition 15 can be divided as required.

The use of the strap 63 is shown in FIGS. 1, 5A and 5B. As shown, the buckle 632 is formed with a large hole 6341 and a small hole 6342. The large hole 6341 is adapted to engage the knob 62, while the small hole 6342 adapted to engage the upper groove and lower groove 6211 and 6212. When in use, first engage the small hole 6342 of one end of the strap 63 with the lower groove 6212 of the knob 62, place the handle of a luggage 7 on the strap 63, and then engage the small hole 6342 of another end of the strap 63 with the upper groove 6211.

The invention is naturally not limited in any sense to the particular features specified in the forgoing or to the details of the particular embodiment which has been chosen in order to illustrate the invention. Consideration can be given to all kinds of variants of the particular embodiment which has been described by way of example and of its constituent elements without thereby departing from the scope of the invention. This invention accordingly includes all the means constituting technical equivalents of the means described as well as their combinations.
