Description
AN EXPANSIBLE CASE
This invention relates to an expansible case of the kind comprising a top wall, a bottom wall, expansible side walls between the top and bottom walls comprising a plurality of rigid side wall elements which extend around the entire periphery of the case and which are connected together in a manner allowing relative axial movement therebetween for moving the side wall elements between an axially contracted condition and an axially expanded condition and latching means for retaining the side wall elements in either of said axially contracted or expanded conditions. The case is intended to be easily convertible between at least two different sizes for altering its capacity. In particular, but not exclusively, the case may comprise an attach case or a suitcase.
An expansible case of the kind referred to is described in US-A-4844215 and has three side wall elements; namely a top side wall element connected to the top wall, a bottom side wall element connected to the bottom wall and an intermediate side wall element. The top and bottom side wall elements define pockets which open towards each other and within which the intermediate side wall element is slidably received in "telescoping" fashion. When the side wall sections are in their contracted condition, the intermediate side wall section is received fully within each of the two pockets and the top and bottom side wall sections meet so as to completely cover and obscure the intermediate side wall section. When the side wall sections are in their expanded condition, the top and bottom side wall sections are spaced apart and the intermediate side wall section is almost fully exposed.
In the known expansible case of the kind referred to described in US-A-4844215, the relative axial movement between the intermediate side wall section and each of the top and bottom side wall sections is relatively large when the side wall sections are moved from one to the other of said axially expanded and contracted conditions. This may lead to "snagging" of the side wall sections during their relative sliding movement if the side wall sections do not remain in truly coaxial relation during this relative sliding movement. Furthermore the intermediate side wall section may become scored or marked by its sliding movement within the pockets of the top and bottom side wall sections. Such scoring or marking of the intermediate side wall section would be readily visible when the latter is fully, exposed in the axially expanded condition of the side wall sections.
The present invention seeks to provide an expansible case of the kind referred to in which the disadvantages referred to above are, at least to a large extent, overcome.
According to one aspect of the present invention an expansible case of the kind referred to is characterised in that each side wall element is also axially movable relative to each of the top and bottom walls.
The provision of a plurality of side wall sections which are axially movable both relative to each other and relative to the top and bottom walls ensures that for a given degree of axial expansion or contraction of the side walls the expansion or contraction is taken up by relatively small axial movements of each of the said side wall sections. Thus the chances of the side wall sections "snagging" during their relative sliding movement is reduced.
Preferably the connection between the or each adjacent pair of side wall elements comprises a sliding portion of one side wall element of the pair slidably received in a pocket of the other side wall element of the pair. Conveniently the or each pocket is in the form of a slot having spaced apart sides and a restricted mouth opening and the or each sliding portion has a shank portion having a width less than the dimension of the said mouth portion and an enlarged head having a width greater than the dimension of the said mouth portion but no greater than the spacing apart of the said spaced apart sides of the slot.During assembly of adjacent side wall elements, the sides of the pocket-defining slot are resiliently urged apart to enlarge the mouth opening thereby enabling insertion of the enlarged head of the sliding portion through the mouth opening so as to be positioned between the spaced apart sides of the slot.
Preferably each side wall element has the said sliding portion at one of its opposite axial ends and the said pocket at the other of its opposite axial ends. This construction is advantageous since all the side wall elements can be of the same basic design. Alternatively, however, the side wall elements could, for example, comprise a first set of side wall elements having pockets at their opposite ends and a second set of side wall elements having sliding portions at their opposite ends.
Conveniently the side wall elements are made of a plastics or metallic, e.g. aluminium, material. Preferably the side wall elements are formed of extruded lengths of plastics or metallic material which are subsequently shaped and joined together into endless forms.
Suitably the said side wall elements comprise axially spaced apart first and second groups of side wall elements and an intermediate side wall element disposed between said first and second groups of side wall elements, the said first group being arranged between the intermediate side wall element and the top wall and the second group being arranged between the intermediate side wall element and the bottom wall. The latching means may serve to retain both the first and second groups of side wall elements in their contracted or expanded conditions. Alternatively the latching means may comprise first and second latch means acting to retain the first and second group of side wall elements, respectively, in their axially contracted or expanded conditions.
Conveniently the case may be provided with optionally retractable wheels and a handle device, e.g. a strap or rigid handle. Suitably the handle device comprises a rigid handle structure movable between a retracted position and an operational position. In this event, if the wheels are also moveable between retracted and operational positions, actuating means may be provided to cause the wheels to move between their retracted and operational positions on movement of the handle structure between its retracted and operational positions, respectively.
According to another aspect of the present invention a case having wheels each movable between an inoperative, retracted position and an operative, transport position and a handle structure movable between an inoperative, first position and an operative, second position, is characterised by actuating means operative to cause the said wheels to move between their retracted and transport positions on movement of the handle structure between its first and second positions, respectively.
Conveniently the handle structure comprises a pair of spaced apart, parallel elongate members which are connected by a handle bar and are slidably mounted on the case, e.g.
in its bottom wall, for movement of the handle structure between its first and second positions, the said actuating means being arranged to convert the translatory motion of the sliding elongate members into movement, e.g. turning movement, moving the wheels between their retracted and transport positions. Suitably a pair of wheels are provided which are respectively rotatably mounted on a pair of elongate wheel carriers, each wheel carrier being jour naIled for turning movement about its longitudinal axis which is disposed perpendicular to the directton of the wheel axis. Conveniently the actuating means includes a camming arrangement. Alternatively the actuating means may comprise a rack and pinion device.

Figure 9 is a view from below of another embodiment
of case according to the invention.
Figures 1 and 2 show an expansible case, generally designated by the reference numeral 1, in a contracted condition and an expanded condition, respectively. The case 1 has a top wall 2, a bottom wall 3 and four expansible side walls 4 between the top and bottom walls 2 and 3. The top and bottom walls may be formed of any suitable material but are typically moulded from plastics material, e.g. ABS resin.
The side walls 4 comprise a plurality of rigid side wall elements connected together. In particular the side walls 4 comprise a top wall section 5 integrally joined to, around the periphery of, the top wall 2, a bottom wall section 6 integrally joined to, around the entire periphery of, the bottom wall 3, an intermediate wall element 7 extending continuously around the entire periphery of the case, relatively slidable wall elements 8-11 arranged in a first group between the intermediate wall element 7 and the top wall 2 and relatively slidable wall elements 12-14 (see
Figure 6) arranged in a second group between the intermediate wall element 7 and the bottom wall 3.
The wall elements 9-14 are all of generally the same design being made from a length of extruded metallic material, e.g. aluminium, or plastics material formed into a endless generally rectangular band and joined end to end.
The wall element 8 is made in a similar manner but from a different section extrudate. As can be seen in Figures 36, the wall elements 9-14 are of generally Y-shaped section each having a shank portion 10a (only one wall element 10 will be described in detail with reference to Figure 3) with an enlarged head 109, e.g. of arrowhead section, and, integrally joined to the shank portion 10a, a pocketdefining portion lOb in the form of a slot having a bottom wall lOc, spaced apart, generally parallel side walls 10d and 10e and a restricted mouth opening 10f.
If the wall elements 7-14 are made of lengths of ex truded plastics material they are formed into endless bands by heating them at their corner regions (and any other region where it is desired to shape the extrudate), forming the heat softened regions around a profile former and finally bonding the opposite ends together. If the wall elements 7-14 are made of lengths of extruded metallic material, they are formed into endless bands by cutting away, e.g. by routing or milling, the inner side wall 1Ob in the corner regions of the extrudate, bending the extrudate to the appropriate shape and joining the opposite ends together, e.g. by adhesive, welding, riveting or the like. If the formed metallic bands are made of aluminium they may then be anodised.
The wall elements 8-14 are joined together by pushing the enlarged head lOg of one wall element through the restricted mouth portion 10f of the adjacent wall element.
The angled arrowhead of the head 109 causes the side walls 10d and 10e to be resiliently urged apart as the head 109 passes through the mouth opening 10f until the head becomes fully seated in the pocket-defining portion 10b and the side walls resiliently return to their spaced apart parallel relationship. In this manner the enlarged head of each wall element 8-10 and 13 and 14 is received in the pocketdefining portion of its adjacent wall element. The enlarged head of the wall elements 11 and 12 are received in similar pocket-defining portions 15 and 16 at opposite axial ends of the intermediate wall element 7. It will be seen from Figure 6 that the bottom wall section 6 has a shank portion 17 with an enlarged head 18 which is slidably received between the spaced apart side walls of the wall element 18.
As shown in Figures 1 and 2, four spring-loaded catches, generally designated 26, are provided on the top and bottom side walls. Each catch 26 has a first catch part 26a connected to the top wall section 5 and a second catch part 26b connected to the bottom wall section 6. The first and second catch parts slidably interengage with each other and guide relative axial movement of the wall elements when the case 1 is moved between its expanded and contracted conditions. The catch parts 26a, 26b are spring biased apart so that the case normally adopts an expanded condition. However the top and bottom walls can be pressed together against the spring biasing into a contracted condition, in which condition the catch parts 26a, 26b can be releasably locked together.
The lid 2 is openable and closable about one or two hinging axes and the wall element 8 has a projecting lip 20 designed to interfit in a channel-shaped groove 21 formed in the top wall section 5 when the lid is closed.
The head of each catch part 26a may be formed as releasably lockable catch parts 23 and 24 (see Figure 5) for enabling the lid 2 to be held in, or released from, its closed position. The lid 2 may be hinged to open or close about hinges on the bottom side wall (as viewed in Figures 1 and 2). Alternatively, or in addition, the top wall 2 (and top wall section 5) may be hinged and separated along the chain line 25 shown in Figure 1 to permit opening and closing of the top wall.
The side wall elements 7-14 are axially movable relative to each other and relative to the top and bottom wall sections 5 and 6. There are thus eight elements which take up the expansion or contraction of the case 1. Typically the outer depth of the case 1 changes from 200 mm in its contracted condition to 264 mm in its expanded condition.
Thus each of the eight elements take up 8 mm of movement.
The wall element are unlikely to snag during such relatively small axial sliding or "telescoping" movements. Furthermore any scratching of the shank portions of the wall elements caused by the relative axial sliding movements will be at least partly obscured by the side walls 10d and 10e even when the case is fully expanded.
Figures 7 and 8 show alternative, less preferred designs of wall elements (only one group of wall elements being shown for simplicity). In Figure 7, each group of side wall elements comprises two basic designs of side wall element; namely a side wall element 30 having sliding portions at each of its opposite axial ends and a side wall element 31 having pockets at each of its opposite axial ends. In Figure 8, each group of side wall elements comprises three basic designs of side wall element; namely side wall elements 30 and 31 of the types shown in Figure 7 and side wall element 32 of similar design to elements 9-14 shown, in Figure 6.
The invention has been described in particular with reference to the provision of two distinct groups of side wall elements separated by an intermediate side wall element of generally greater axial extent. However in alternative embodiments the side wall elements may be arranged in a single group or in more than two axially spaced apart groups of side wall elements spaced apart by intermediate side wall elements.
An alternative design of expansible case 34 is shown in
Figure 9. In particular the case 34 has a handle structure comprising a pair of spaced apart, parallel elongate members 35, 36 connected by a handle bar 37. The elongate members 35 and 36 are slidably received in spaced apart parallel slots 38 and 39, respectively, in the bottom wall 40 of the case. The elongate members 35 and 36 are slidable between an inoperative, first position (left-hand side of Figure 9) and an operative, pulling/pushing second position (right-hand side of Figure 9). A pair of wheels 41 and 42 are rotatably mounted on a pair of wheel carriers 43 and 44, respectively.The wheel carriers 43 and 44 can be swivelled about swivel axes generally parallel to the slots 38 and 39, respectively, for moving the wheels between inoperative, retracted positions (left-hand side of
Figure 9) and operative, transport positions (right-hand side of Figure 9 in which wheel 42 is shown swung clear of wheel recess 45 formed in the bottom wall 40). Although not shown, an actuating mechanism is provided for swiveling the wheel carriers 43 and 44 on sliding movement of the elongate members 35 and 36 within the slots 38 and 39. For example, the carriers 43 and 44 may include elongate portions arranged coaxially with the slots 38 and 39. If the elongate portions and/or the elongate members are tubular, they can be arranged to be received coaxially one within the other.Various camming arrangements can then be employed to swivel the wheel carriers on sliding of the elong,ate members 35 and 36 between the first and second positions. For example, a helical cam slot could be provided in the elongate portion (or elongate member) with a cam follower on the telescopically received elongate member (or elongate portion). Alternatively the elongate members could have a non-circular, e.g. square, crosssection and have a 90" twist along their length. On moving the elongate members through the similarly shaped, noncircular bores of collars attached to the elongate portions, a 90" swiveling movement of the wheel carriers is achieved. Another wheel carrier swiveling mechanism comprises a rack and pinion device. With a rack and pinion device, a rack would be provided on each of the elongate members which, on sliding movement would rotate pinion wheels. The pinion wheels would each have a worm drive acting on the elongate portions to swivel the latter. In this event the elongate portions and elongate members would not be coaxtally disposed. Whatever actuating mechanism is chosen1 the aim is to cause the wheels 41 and 42 to move between their retracted and transport positions on movement of the handle structure between its first and second positions, respectively.
Although the sliding handle structure and swiveling wheels are intended to be incorporated in an expansible case according to the invention, it will be appreciated that they can also be incorporated in non-expansible cases.
