The present invention relates to a suitcase and a method of manufacture thereof, in particular, but not exclusively wherein the contents of the suitcase are protected from wear and tear.
The term luggage refers to any number of bags, suitcases and/or containers which hold a traveller's articles during transit. Luggage has changed over time. Historically, the most common types of luggage were chests or trunks. In more recent times, smaller and more lightweight suitcases and bags that can be carried by an individual have become the main forms of luggage.
A suitcase is a general item that may be wheeled or non-wheeled luggage, as well as soft or hard sided baggage. A suitcase is often a somewhat flat, generally rectangular shaped item with rounded or square corners and is made from materials that more or less keep their intended shape. Many modern suitcases have a built in set or sets of wheels enabling them to be pulled along flat hard surfaces, most commonly by an extendable telescopic towing handle. The extendable towing handle is conveniently moveable between a retracted stowage position and an extended user towing position.
It is a convenient and commercially conventional practice to define a ‘hard’ suitcase as one in which the walls, top and bottom of the suitcase cannot easily be penetrated by a needle or blade, whereas a ‘soft’ suitcase is one than can be readily so penetrated.
Suitcases are often used by travellers on airlines. As is well known airlines impose a weight limit that each passenger may check in without attracting a surcharge. As such, whether in relation to hard or soft suitcases, it is a commercial imperative to ensure that as much as possible of this weight allowance is borne by the contents of the suitcase and is not due to the suitcase itself.
It is a related requirement that as large a portion of the volume of a suitcase should be free for the use of the traveller as possible. However, a common means of construction of the telescopic towing handle is to mount a pair of receiving tubes within the body of the suitcase, secured by way of a base panel of the suitcase, and extending to or through an upper panel of the suitcase, and to slidably locate a pair of tubes, which make up the side limbs of a U-shaped handle assembly forming the extendable towing handle, within the receiving tubes. In practice, while providing for a robust construction, the presence of these tubes adds considerably to the overall weight of the suitcase and reduces the interior volume of the suitcase available for use by a user of the suitcase.
Accordingly, there is need for a towing handle that has the advantages provided by allowing for towing of a wheeled suitcase, while eliminating or at least mitigating the disadvantages of telescopic towing handle arrangements.
It is an advantage of the present invention that it provides a suitcase and a manner of manufacture of such a suitcase that addresses these problems. Other advantages of the present invention will also be apparent from the following description.
According to a first aspect of the present invention, a suitcase comprises a first load container section defining at least a first part of a volume for receiving a load and a second container section for cooperation with the base load container section to enclose the volume wherein the suitcase comprises a base region provided with one or more wheel assemblies, in which the suitcase further comprises an upper region at or on which is provided a towing handle adapted to be moved about a single point of contact between a stowed position and a deployed position.
Preferably, the towing handle is connected at one end to the single point of contact.
Preferably an end of the towing handle remote from the single point of contact is provided with a grip portion.
Preferably the towing handle may be secured in either the stowed position or the deployed position.
Preferably, in the stowed position the towing handle is received within a recess provided in one of the first or second container sections.
More preferably, the towing handle is substantially L-shaped. More preferably the recess is substantially L-shaped.
Alternatively, in the stowed position the grip portion of the towing handle rests or is disposed against the upper section of the suitcase. Alternatively, in the stowed position the grip portion of the towing handle is disposed substantially orthogonally to an upper surface of the suitcase.
According to a second aspect of the invention, a method of manufacture of a suitcase comprises forming a first load container section defining at least a first part of a volume for receiving a load, forming a second container section for cooperation with the base load container section to enclose the volume, securing one or more wheel assemblies to a base region of the volume, and further providing at or on an upper region of the volume a towing handle adapted to be moved about a single point of contact between a stowed position and a deployed position.
The invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
Referring first to
The first and second container sections 4,6 are intended to connect one with the other when the suitcase is closed, as is shown in the Figures, and the first and second container sections 4,6 are each formed with complementary profiled stiffening ribs 18,20. The first and second container sections 4,6 are hindgedly connected at one edge to one another by a suitable hinge arrangement (not shown) and releasably held in a closed condition by a suitable zip fastener arrangement 22 in a manner known to those skilled in the art.
It can be seen that the lower faces of the first and second container sections 4,6 together provide for a base region of the suitcase 2. The base region is provided in any suitable manner with four wheel assemblies 22, one at each lower corner of the suitcase 2.
The upper faces 12,16 of the first and second container sections 4,6 provide for an upper region of the suitcase 2. A towing handle 30 is provided at an upper surface of the upper region. The towing handle 30 is adapted to be moved about a single point of contact 32 between a stowed position (
It can be seen that the single point of contact 32 is located centrally at the rear of the upper face 12.
In the illustrated embodiment, the towing handle 30 comprises a substantially L-shaped member, a first limb 34 of which is hingedly or pivotally connected at one end to the first container section and a second limb 36 of which is provided with a grip portion. Preferably, the grip portion is provided with a shaped portion by which a user may conveniently grasp the towing handle when towing the suitcase, as well as manoeuvre the towing handle 30 between each of the stowed position and the deployed position.
The first limb 34 and the second limb 36 are provided at a fixed angle to one another. Conveniently this is achieved by forming the towing handle 30 of unitary construction.
The first limb 34 and the second limb 36 are each rigid or substantially rigid. Conveniently this may be achieved by forming the towing handle 30 from a plastics or other suitable material.
In an alternative embodiment (not shown) the first limb 34 may be formed of nested tubes allowing the first limb 34 to be telescopic in nature.
The towing handle 30 may be provided with suitable releasable securing means to secure the towing handle 30 in one or both of the stowed position and the deployed position. Conveniently the releasable securing means may be actuated by a button 38 on or adjacent to the grip portion. Alternatively, the releasable securing means may comprise a clip or other moulding provided on the suitcase to releasably retain the towing handle 30 in the stowed position.
In this embodiment, it can be seen that in the stowed position the towing handle 30 sits in a suitably shaped recess 42, either flush with the surfaces of the first container section or alternatively set back therefrom, such that when stowed the towing handle 30 is protected from damage, and in particular the single point of contact between the towing handle 30 and the suitcase 2 is protected from impact. It can be seen that a flat substantially vertical surface of the recess 42 also serves to prevent the towing handle 30 from moving other than in a single plane between the stowed position and the deployed position.
In comparison to known constructions having a telescopic towing assembly including receiving tubes extending with a load receiving volume, the present invention provides weight savings—as the need to provide the tubes to provide a telescopic towing handle assembly is eliminated—and provides additional interior volume available for use within the suitcase by a user—as the tubes of a telescopic handle assembly are no longer present within the suitcase. The embodiment of
A second embodiment of the invention is shown in
The first container section 104 can be seen to comprise a main face 108, a lower face (not shown), side walls 110 and an upper face 112. It can be seen that the lower face of the first container section provides for a base region to which two wheel assemblies 124 have been attached in any suitable manner to provide means to pivot the suitcase about a lower edge to enable towing of the suitcase. Further wheel assemblies or feet (not shown) to support the suitcase when not being towed may be provided at other corners of the base region.
The upper region of the first container section 104 provides for an upper surface of the suitcase. A towing handle 130 is provided at the upper surface. The towing handle 130 is adapted to be moved about a single point of contact between a stowed position (
In the illustrated embodiment, the towing handle 130 comprises a substantially L-shaped member, a first limb 134 of which is hingedly or pivotally connected at one end to the first container section 104 and a second limb 136 of which is provided with a grip portion. Preferably, the grip portion is provided with a shaped portion by which a user may conveniently grasp the towing handle when towing the suitcase.
The towing handle 130 may be provided with releasable securing means to secure the towing handle 130 in one or both of the stowed position and deployed position. Conveniently the releasable securing means may be actuated by a button 138 on or adjacent to the grip portion.
In this embodiment, it can be seen that an internal surface following the limbs 134,136 of the towing handle 130 fits around external dimensions of the suitcase 102, such that in the stowed position the grip portion of the towing handle 130 follows and sits adjacent the side wall 110 of the first container section 104.
