Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a means for transporting a suitcase, a bag and a similar travel package, and more particularly to a rolling aid for facilitating the transportation of such a package.

[0002]

BACKGROUND OF THE INVENTION Numerous attempts have been made to make it easier for travelers to walk around the long corridors of airports while carrying their bags. There are various types of wheelbarrows, such as wheelbarrows that can be permanently used at airports or other transportation stations, or foldable wheelbarrows carried by travelers that can be folded into a compact article after use. Widely used. Suitcases are also available on the market that have built-in rollers attached to the bottom side of the suitcase and forming an integral part of the suitcase.

[0003]

Although these solutions are widespread, they do not provide a satisfactory solution to the problem. That is, in practice, the foldable wheelbarrow is too bulky, even when folded, both during travel and during continuous use.
It tends to be troublesome to handle.

Built-in rollers generally have a small diameter,
It is therefore unstable, even against very small obstacles on the floor, causing the suitcase to become stuck or to fall. Furthermore, because of the small size of these built-in rollers, it is necessary to install four rollers. In the case of only two, a larger roller would be provided on one side of the suitcase and a special retracting handle would be required, which of course makes the suitcase more complicated and more expensive. Make something

Suitcases with removable castors or rollers are also known. That is, these casters or rollers are removed one by one and put away when not in use, after which they may be misplaced or lost altogether.

The present invention seeks to eliminate the above and other deficiencies of conventional rolling aids for suitcases.

[0007]

Therefore, according to the present invention,
A pocket-sized roller device is provided for ease of movement of a suitcase and its like loads that is removably attached to the bottom of the suitcase when in use and adapted to be removed when not in use. This roller device comprises a block-shaped housing having a flat top and a block-shaped housing mounted at a distance from the housing.
A pair of rollers and a looped strap with a buckle secured to the housing and adapted to be clamped around the suitcase to removably tie the housing to the bottom of the suitcase.

[0008]

The invention will be more clearly understood and its advantages will be better appreciated by considering the following description of a preferred embodiment, given by way of example only, with reference to the accompanying drawings, in which:

1 and 2 there is shown a roller device, generally designated by the numeral 10, consisting of a rectangular prismatic housing 12, which is preferably manufactured by plastic injection molding. The housing has a pair of opposed block-shaped portions 14, 16 designed to accommodate a pair of rollers designated 18,20. The block-shaped part 14 defines a hollow cavity 22 for mounting a shaft 24 with rollers 18, the part 16 located on the other side of the housing 12 being of the same construction as the part 14.

The side walls 26, 28 of the housing 12 together with the bottom wall 30 define a hollow compartment 32. This compartment 32 is a buckle
Suitable size for storing a folded strap 34 with 36 therein. Advantageously, the bottom wall 30 comprises slits 30a, 30b, 30c, 30d and the strap 34 is threaded through said slits rather than being fixed by external means such as rivets or by gluing.

Provided at the open top of compartment 32 are four detents 40 designed to form a stop for retaining folding strap 34 within compartment 32 when the roller system is not in use. Is preferred.

In addition, shallow recesses or depressions 42 are made at both ends of the housing for reasons that should be explained below.

In use, as illustrated in FIGS. 3 and 4, the roller device 10 is attached to the bottom wall of the suitcase 50 by the strap 34 of the device and tightened by the buckle 36. Its strap extension 34a
Is passed under the fastening straps 52, 54 attached to the suitcase 50 (if the suitcase has fastening straps). The strap 34 includes a handle loop 34 by which the user can lift and drag the suitcase.
Preferably 6 is provided.

Thus, the recesses 42 and the straps 34 pass over the recesses 42 (FIG. 1) so as not to prevent the upper surface of the housing 12 from making direct and stable contact with the bottom of the suitcase 50. It will be clear that it will be possible.

The roller device 10 is readily adapted to be used in pairs, as shown in FIG. 5, whenever it is convenient to do so.

FIG. 6 shows a rubber strap in this embodiment.
Illustrated is a roller device 10 having a housing 12 that houses 34, and a sturdy, thin rope 60 is used to handle extension 34a in a similar manner.

When not in use, the roller device 10 is completely separated from the items to be transported, such as a suitcase, bag or other luggage, and the straps are conveniently folded back into the storage compartment 32. It is possible that Due to its small size, the device 10 can be easily stored without any of the inconvenience and inconvenience previously experienced with optionally collapsible barrows or individual rollers.

The diameter of the rollers 18, 20 may be much larger than the diameter of the rollers or casters used in the suitcases with built-in rollers, and further, the suitcase with the roller device of the present invention may have built-in rollers. It is worth noting that it can travel at greater distances from the surface than a suitcase. Therefore, the rolling becomes easier and smoother especially on an irregular floor or an uneven floor.

In the embodiment shown in FIG. 7, the roller device 11
And, instead of the retaining detent 40 (FIG. 1), it has a lid 170 that fits snugly over the strap storage compartment 132, for example by friction or snap.

The lid 170 has a reduced width in its central portion, and at least this central portion is provided with one or two drawer cuts 172.

The strap 134 may be attached to the lid 170 in the manner illustrated in FIG. 8 or 9.

Recessed windows 174 may be provided for insertion of identification cards, advertising media, logotypes and the like.

Of course, this lid can also function as a handle (see 34b in FIG. 3).

It can be expected that the roller device according to the invention can be easily manufactured by mass production at very low cost and even become a promotional gift for airlines and travel agencies.

It will be readily appreciated by those skilled in the art that various changes, modifications and alterations can be made to the invention as described above without departing from the scope of the invention as defined in the appended claims. right.
