Definitions
- the present invention relates to a frame construction for a piece of luggage according to the preamble of claim 1 and to a method of fastening a shell to a frame construction of a piece of luggage with such a frame construction according to claim 15.
- Suitcases typically comprise a frame construction with shells that are articulately joined to one another by means of hinges provided on the frame construction.
- a suitcase is known in which the suitcase shells are connected to the frame construction through adhesive bonding.
- Other types of connections between the shells and the frame constructions are however possible, too.
- EP 2 672 857 A1 discloses a suitcase, wherein the shell is connected to the frame constructions by means of stitching.
- a frame construction for a piece of luggage which comprises a shell with an end portion and a frame.
- the frame comprises a profile extending in an extension direction and having a profile base and a first profile wall and a second profile wall, a seat for receiving the end portion of the shell being delimited by opposing first and second inner surfaces of said first and second profile walls.
- the frame construction further comprises at least one fastening element, wherein said fastening element is configured to be removably inserted in the seat of the profile so as to removably fasten the end portion of the shell being received in the seat to the frame.
- the frame construction comprises a frame with a profile into which an end portion of a shell can be received and fastened by means of a fastening element.
- a tedious fastening by means of gluing or sewing, for example, is omitted.
- the fastening element is not permanently fixed to the frame, the end portion of the shell is likewise not permanently fixed to the frame. Instead, the shell can easily be removed in that the fastening element is removed from the frame.
- fastening element which, when inserted in the seat of the profile, extends along said extension direction of the profile around substantially the entire frame.
- a fastening element which, when inserted in the seat of the profile, extends only partially along the extension direction of the profile. In the latter case, it is preferred to provide two or more such fastening elements which are distributed along a circumference of the frame.
- the fastening element can be fastened to the frame by means of a friction fit and/or a positive-locking fit.
- a friction fit can be caused by a static friction exerted between effective surfaces of the fastening element and the end portion of the shell and of the fastening element and the profile, in particular the inner surface of the profile wall, respectively.
- the fastening element can be clamped in the seat, whereby also the end portion of the shell is clamped in the seat.
- the friction fit has the effect that neither the fastening element nor the end portion of the shell can be removed from the frame without the action of a greater external force.
- the friction fit can be overcome when a certain external force is applied and, as a result, the fastening element and the shell can be removed from the frame.
- a positive-locking fit established between the fastening element and the end portion of the shell within the seat of the frame prevents the removal of these components unless a certain external force is applied.
- the distance between the first profile wall and the second profile wall essentially equals the sum of the thickness of the end portion of the shell and the thickness of the fastening element in the region of insertion in the seat of the profile. It is therefore possible to securely fasten the shell to the frame by means of the fastening element only.
- additional fastening means such as an adhesive is nevertheless possible. For example, it is conceivable to glue the fastening element to the end portion of the shell before they are inserted in the seat of the profile.
- the fastening element can be formed separately from the frame and/or from the shell.
- the fastening element and the shell could be integrally formed on the end portion of the shell such that an insertion of the end portion of the shell leads at the same time to a fastening of the end portion of the shell to the frame.
- the fastening element as a protrusion, such as a tab protruding from the end portion of the shell, which tab engages with a corresponding structure such as a groove provided in the profile.
- the fastening element can be configured such, that when the end portion of the shell is received in the seat, the fastening element may be slid into the profile along said extension direction into a space formed between the end portion of the shell and the first profile wall or the second profile wall, respectively, whilst the end portion of the shell is pressed against the second profile wall or against the first profile wall, respectively.
- the fastening element can be configured such, that when the end portion of the shell is received in the seat, the fastening element may be pushed into a space formed between the end portion of the shell and the first profile wall or the second profile wall, respectively, along a direction transverse to said extension direction whilst the end portion of the shell is pressed against the second profile wall or against the first profile wall, respectively.
- the width of the end portion of the shell is smaller than the clear width between the first and second profile walls of the profile. If now the end portion of the shell is in a first step inserted into the seat of the profile, the above-mentioned space is formed between one of the profile walls and one surface of the end portion of the shell. In a second step it is then possible to insert the fastening element into the space formed between the respective other profile wall and the other surface of the end portion of the shell along the extension direction or along a transverse direction extending transverse to said extension direction.
- the widths of the fastening element and the end portion of the shell in the region of insertion are essentially equal to or even slightly larger than the clear width between the first and second profile walls of the profile, the fastening element will thereby clamp the end portion of the shell within the seat of the profile.
- At least one of the profile walls and the fastening element in each case can comprise at least one retaining structure, said retaining structures being configured to mutually interact with one another such that an additional mechanical fastening of the fastening element in the frame is effected.
- the retaining structure on the fastening element is preferably a first protrusion and the retaining structure on the at least one of the profile walls is preferably a toothing provided on the inner surface of said profile wall and/or a lug extending inwards in the direction of the seat, the first protrusion and the toothing being configured to engage one another and the lug providing a stop for the first protrusion.
- the fastening element can comprise a second retaining structure, preferably in the form of a second protrusion, which, when the end portion of the shell is received in the seat, presses against a first surface of the shell such that an additional fastening of the end portion being received in the seat is effected. That is, it is preferred to design the fastening element in such a way that it effects a clamping force on one of the surfaces of the end portion of the shell.
- the fastening element with an elongate shape being insertable into the seat of the profile, wherein the said first and second retaining structures are arranged on opposite surfaces of the elongate fastening element.
- the free end region of at least one of the profile walls can have a retaining structure, preferably in the form of a lug, extending inwards in the direction of the seat, wherein said retaining structure, when the end portion of the shell is received in the seat, presses against a second surface of the shell such that an additional fastening of the end portion being received in the seat is effected. That is, it is preferred to design at least one of the profile walls in such a way that it effects a clamping force on one of the surfaces of the end portion of the shell.
- the first and second profile walls preferably extend essentially parallel to one another, and/or the second profile wall preferably has a length which is greater than the length of the first profile wall along a direction transverse to said extension direction.
- the profile when seen in the cross-section, the profile preferably has an essentially U-shaped design, wherein the first and second profile walls correspond to the side legs of said "U", respectively, wherein one side leg can be longer than the other side leg.
- the fastening element can be dimensioned such, that a gap is formed between the profile base and a lower side of the fastening element when the fastening element is inserted in the seat of the frame, and/or the fastening element can be dimensioned such, that an upper side of the fastening element is essentially flush with the free end of the second profile wall or that its upper side projects beyond the free end of the second profile wall when the fastening element is inserted in the seat of the frame.
- the gap serves the purpose of compensating any tolerances between the fastening element and the shell profile. Whereas a fastening element being flush with the profile wall is aesthetically pleasing, a protruding fastening element brings the advantage that the protruding portion can easily be grasped and can thus be better removed from the frame.
- the shell may have a curvature dividing the shell into the said end portion and a main portion, whereby the main portion is arranged off-set with respect to the end portion, wherein the length of the second profile wall essentially equals the overall length of the end portion and the curvature in a direction transverse to the extension direction, and wherein the second protrusion, when the fastening element is inserted in the seat of the frame, preferably presses against the first surface of the shell in the region of the curvature.
- the main portion of the wall is preferably essentially flush with the first profile wall of the frame, i.e. the first profile wall and the main portion preferably extend in a common plane.
- the frame construction preferably comprises a further frame, wherein the frame comprises a connection profile and the further frame comprises a further connection profile being designed complementary to the connection profile of the frame, the connection profile and the further connection profile being configured to enter into a preferably positive connection with one another.
- the frame construction can comprise two frames which preferably in each case comprise a profile as described above. It is also preferred that the frames are connectable to one another by means of their complementary connection profiles.
- the suitcase shells are preferably connected with each other by one or more articulated joints such as hinges. By pivoting the suitcase shells about the pivot axis provided by the articulated joints it is possible to open and close the suitcase shells of the suitcase. In the closed position, the complementary designed connection profiles of the frames come into engagement with each other.
- a piece of luggage preferably a suitcase, with a frame construction as described above is provided, wherein the end portion of the shell is received in the seat of the frame and removably fastened by means of the fastening element being removably inserted in the seat of the frame.
- Said piece of luggage preferably comprises a frame construction having two frames as described above, wherein each frame comprises a suitcase shell removably fastened by means of a fastening element.
- a method of fastening a shell to a frame construction of a piece of luggage comprises the steps of:
- FIG. 1 A suitcase 1000 comprising two suitcase shells 100, 100' and a frame construction 10 is shown in Figure 1 .

- the liner 6 is a single layer material consisting of a two-piece fabric, wherein a thick and elastic fabric piece 63 is sewed to a thin and inelastic fabric piece 64.
- one elongate member 62 in the form of a plastic string is attached to the liner 6, wherein the two pieces of fabric are sewn around the string 62 such that the string 62 is received within the fold 61 of the liner 6.
- Said fold 61 together with the string 62 is inserted into the seat 28 of the U-shaped profile 2 such, that the thick and elastic fabric piece 63 extends around the first lateral edge region 51 of the strip 5 and the thin and inelastic fabric piece 64 extends around the second lateral edge region 52 of the strip 5 once the strip 5 is inserted into the grooves 26, 27 of the U-shaped profile 2.
- the frame construction as described above is not restricted to the suitcase shown in the present figures. Instead, it is conceivable to provide such a frame construction to other types of suitcases, e.g. suitcases without wheels, and in particular to any type of luggage comprising two shells to be interconnected.
- FIG. 1 to 12 the frame construction 10, 10' comprising a shell profile 4, 4' and a fastening element 42, 42' according to a first embodiment is shown, whereas figures 13 to 15 depict a second embodiment and figures 16 to 17c depict a third embodiment of a frame construction, respectively.
- the main difference between said embodiments is that the shell 100 and the fastening element 42, 62 according to the first and second embodiment are designed as individual parts, whereas in the third embodiment, the fastening element 106 is an integral part of the end portion 101 of the shell 100.
- the fastening element is provided by means of the elongate member 62 of the liner 6 as described above, whereas the fastening element 42 according to the first embodiment corresponds to an element being designed different from and optionally also provided in addition to the elongate member 62.

- the fastening element 42' can be seen as a clamping element which is clamped within the space 412' formed between the profile wall 44', 45' and the shell 100', wherein the fastening element 42', the seat 41' and the end portion 101' of the shell 100' are dimensioned such, that the distance between the first profile wall 44' and the second profile 45'wall essentially equals the sum of the thickness of the end portion 101' of the shell 100' and the thickness of the fastening element 42' in the region of insertion of the end portion 101' in the seat 41' of the shell profile 4'.
- the fastening element 42' is configured such, that when the end portion 101' of the shell 100' is received in the seat 41', the fastening element 42' may be slid into the shell profile 4' along an extension direction E or may be pushed along a direction TE transverse to said extension direction E into the space 412' formed between the end portion 101' of the shell 100' and the first profile wall 44' or the second profile wall 45', respectively, whilst the end portion 101' of the shell 100 is pressed against the second profile wall 45' or against the first profile wall 44', respectively.
- the fastening element 42' and as a result also the end portion 101' of the shell 100', are thereby fastened by means of a friction fit and a positive-locking fit only, i.e. without the need of any additional fastening means such as an adhesive or by sewing, for example.

- Said lug 414' provides a stop for the retaining structure in the form of a protrusion 413' formed on the fastening element 42', such that a removal of the fastening element 42' being inserted into the shell profile 4' out of the shell profile 4' is made more difficult, e.g. because a greater amount of force is needed for the removal.
- the fastening element 42' is thus engaged or snapped in the shell profile 4'.
- the fastening element 42' comprises a further retaining structure 415' in the form of a further protrusion, which, when the end portion 101' of the shell 100' is received in the seat 41', presses against the surface 102' of the shell 100' facing said further retaining structure 415', such that an additional fastening of the end portion 101' being received in the seat 41' is effected.
- the fastening element 42' has an elongate shape with an upper side 418' and a lower side 419', wherein the retaining structures 413', 415' are arranged opposite one another and in each case extend along an entire width WF of the fastening element 42'.
- the fastening element 412' essentially takes the form of an "L". Furthermore, the fastening element 42' extends, when inserted in the seat 41' of the shell profile 4', partially along the extension direction E of the shell profile. In fact, the fastening element 42' has a width WF that is a small fraction of the extension lengths of the first and second profile walls 44', 45' along the extension direction E. It is therefore conceivable to provide two or more, in particular a plurality of such fastening elements 42' which can be distributed along said extension direction E around substantially the entire frame 1.
- the fastening element 42' is dimensioned such, that a gap 417' is formed between the profile base 43' and the lower side 418' of the fastening element 42' and that the upper side 419' of the fastening element 42' is essentially flush with the free end 411' of the second profile wall 45' when the fastening element 42' is inserted in the seat 41' of the frame 1'.
- the free end region 48' of the first profile wall 44' has a retaining structure 416' in the form of a lug extending inwards in the direction of the seat 41', wherein said retaining structure 416', when the end portion 101' of the shell 100' is received in the seat 41', presses against the surface 103' of the shell 100' facing said retaining structure 416' such that an additional fastening of the end portion 101' being received in the seat 41' is effected.
- the first and second profile walls 44', 45' extend essentially parallel to one another, wherein the second profile wall 45' has a length LP2 which is greater than the length LP1 of the first profile wall 44' along the transverse direction TE.

- the region of the second profile wall 45' that is extended with respect to the first profile wall 44' is arranged offset with respect to the remaining part of said second profile wall 45'.
- a groove 420' is formed, within which groove 420' the retaining structure 413' of the fastening element 42' can be received.
- the shell 100' in turn has a curvature 104' dividing the shell 100' into the end portion 101' and a main portion 105', whereby the main portion 105' is arranged off-set with respect to the end portion 101', and wherein the length LP2 of the second profile wall 45' essentially equals the overall length of the end portion 101' and the curvature 104' in the transverse direction TE.
- the second retaining structure 415' of the fastening element 42' presses against the first surface 102' of the shell 100' in the region of the curvature 104'.

Abstract
Description
- The present invention relates to a frame construction for a piece of luggage according to the preamble of
claim 1 and to a method of fastening a shell to a frame construction of a piece of luggage with such a frame construction according toclaim 15. - Suitcases typically comprise a frame construction with shells that are articulately joined to one another by means of hinges provided on the frame construction. From
EP 1 867 246 A1EP 2 672 857 A1 - Particular drawbacks of such connections are their laborious manufacturing and the fact that the connecting means such as the adhesive or the stitching are visible and seem aesthetically intrusive. Furthermore, although such a permanent fixation can be advantageous due to the durability of fixation, it might nevertheless be desirable to replace broken parts of the suitcase.
- It is therefore an object of the present invention to provide an improved frame construction for a piece of luggage. In particular, it is an object to provide a frame construction which enables a simple but reliable manufacturing and allows the replacement of damaged parts.
- This object is achieved by means of a frame construction according to
claim 1. In particular, a frame construction for a piece of luggage is provided, which comprises a shell with an end portion and a frame. The frame comprises a profile extending in an extension direction and having a profile base and a first profile wall and a second profile wall, a seat for receiving the end portion of the shell being delimited by opposing first and second inner surfaces of said first and second profile walls. The frame construction further comprises at least one fastening element, wherein said fastening element is configured to be removably inserted in the seat of the profile so as to removably fasten the end portion of the shell being received in the seat to the frame. - In other words, the frame construction comprises a frame with a profile into which an end portion of a shell can be received and fastened by means of a fastening element. A tedious fastening by means of gluing or sewing, for example, is omitted. Moreover, since the fastening element is not permanently fixed to the frame, the end portion of the shell is likewise not permanently fixed to the frame. Instead, the shell can easily be removed in that the fastening element is removed from the frame.
- It is possible to provide one single fastening element which, when inserted in the seat of the profile, extends along said extension direction of the profile around substantially the entire frame. However, it is likewise conceivable to provide a fastening element which, when inserted in the seat of the profile, extends only partially along the extension direction of the profile. In the latter case, it is preferred to provide two or more such fastening elements which are distributed along a circumference of the frame.
- The fastening element can be fastened to the frame by means of a friction fit and/or a positive-locking fit. A friction fit can be caused by a static friction exerted between effective surfaces of the fastening element and the end portion of the shell and of the fastening element and the profile, in particular the inner surface of the profile wall, respectively. Thus, the fastening element can be clamped in the seat, whereby also the end portion of the shell is clamped in the seat. The friction fit has the effect that neither the fastening element nor the end portion of the shell can be removed from the frame without the action of a greater external force. However, since there are no permanent connecting means involved in the fastening of the shell to the frame, the friction fit can be overcome when a certain external force is applied and, as a result, the fastening element and the shell can be removed from the frame. Similarly, a positive-locking fit established between the fastening element and the end portion of the shell within the seat of the frame prevents the removal of these components unless a certain external force is applied. In doing so it is preferred that the distance between the first profile wall and the second profile wall essentially equals the sum of the thickness of the end portion of the shell and the thickness of the fastening element in the region of insertion in the seat of the profile. It is therefore possible to securely fasten the shell to the frame by means of the fastening element only. However, the provision of additional fastening means such as an adhesive is nevertheless possible. For example, it is conceivable to glue the fastening element to the end portion of the shell before they are inserted in the seat of the profile.
- The fastening element can be formed separately from the frame and/or from the shell. Alternatively, it is conceivable to provide the fastening element and the shell as a single component. For example, the fastening element could be integrally formed on the end portion of the shell such that an insertion of the end portion of the shell leads at the same time to a fastening of the end portion of the shell to the frame. In this context, one possibility would be the provision of the fastening element as a protrusion, such as a tab protruding from the end portion of the shell, which tab engages with a corresponding structure such as a groove provided in the profile.
- The fastening element can be configured such, that when the end portion of the shell is received in the seat, the fastening element may be slid into the profile along said extension direction into a space formed between the end portion of the shell and the first profile wall or the second profile wall, respectively, whilst the end portion of the shell is pressed against the second profile wall or against the first profile wall, respectively. In addition or alternatively the fastening element can be configured such, that when the end portion of the shell is received in the seat, the fastening element may be pushed into a space formed between the end portion of the shell and the first profile wall or the second profile wall, respectively, along a direction transverse to said extension direction whilst the end portion of the shell is pressed against the second profile wall or against the first profile wall, respectively.
- It is therefore preferred that the width of the end portion of the shell is smaller than the clear width between the first and second profile walls of the profile. If now the end portion of the shell is in a first step inserted into the seat of the profile, the above-mentioned space is formed between one of the profile walls and one surface of the end portion of the shell. In a second step it is then possible to insert the fastening element into the space formed between the respective other profile wall and the other surface of the end portion of the shell along the extension direction or along a transverse direction extending transverse to said extension direction. If the widths of the fastening element and the end portion of the shell in the region of insertion are essentially equal to or even slightly larger than the clear width between the first and second profile walls of the profile, the fastening element will thereby clamp the end portion of the shell within the seat of the profile.
- At least one of the profile walls and the fastening element in each case can comprise at least one retaining structure, said retaining structures being configured to mutually interact with one another such that an additional mechanical fastening of the fastening element in the frame is effected. The retaining structure on the fastening element is preferably a first protrusion and the retaining structure on the at least one of the profile walls is preferably a toothing provided on the inner surface of said profile wall and/or a lug extending inwards in the direction of the seat, the first protrusion and the toothing being configured to engage one another and the lug providing a stop for the first protrusion. Hence, in addition to a fastening of the fastening element in the seat of the profile by means of a friction fit and/or a positive-locking fit caused by the geometrical dimensions of the fastening element and the end portion of the shell only, it is conceivable to provide additional structures on the profile and the fastening element that can enter into engagement with one another.
- The fastening element can comprise a second retaining structure, preferably in the form of a second protrusion, which, when the end portion of the shell is received in the seat, presses against a first surface of the shell such that an additional fastening of the end portion being received in the seat is effected. That is, it is preferred to design the fastening element in such a way that it effects a clamping force on one of the surfaces of the end portion of the shell.
- To this end it is conveivable to provide the fastening element with an elongate shape being insertable into the seat of the profile, wherein the said first and second retaining structures are arranged on opposite surfaces of the elongate fastening element.
- The free end region of at least one of the profile walls can have a retaining structure, preferably in the form of a lug, extending inwards in the direction of the seat, wherein said retaining structure, when the end portion of the shell is received in the seat, presses against a second surface of the shell such that an additional fastening of the end portion being received in the seat is effected. That is, it is preferred to design at least one of the profile walls in such a way that it effects a clamping force on one of the surfaces of the end portion of the shell. Through the fact that clamping forces can be exerted on both surfaces of the end portion of the shell, once by means of the retaining structure on the fastening element and once by means of the retaining structure on the profile wall, the shell is also secured with respect to a displacement within the frame construction. A dimensionally stable frame construction is thus provided.
- In the region of the seat, the first and second profile walls preferably extend essentially parallel to one another, and/or the second profile wall preferably has a length which is greater than the length of the first profile wall along a direction transverse to said extension direction. Put differently, when seen in the cross-section, the profile preferably has an essentially U-shaped design, wherein the first and second profile walls correspond to the side legs of said "U", respectively, wherein one side leg can be longer than the other side leg.
- The fastening element can be dimensioned such, that a gap is formed between the profile base and a lower side of the fastening element when the fastening element is inserted in the seat of the frame, and/or the fastening element can be dimensioned such, that an upper side of the fastening element is essentially flush with the free end of the second profile wall or that its upper side projects beyond the free end of the second profile wall when the fastening element is inserted in the seat of the frame. The gap serves the purpose of compensating any tolerances between the fastening element and the shell profile. Whereas a fastening element being flush with the profile wall is aesthetically pleasing, a protruding fastening element brings the advantage that the protruding portion can easily be grasped and can thus be better removed from the frame.
- The shell may have a curvature dividing the shell into the said end portion and a main portion, whereby the main portion is arranged off-set with respect to the end portion, wherein the length of the second profile wall essentially equals the overall length of the end portion and the curvature in a direction transverse to the extension direction, and wherein the second protrusion, when the fastening element is inserted in the seat of the frame, preferably presses against the first surface of the shell in the region of the curvature. The main portion of the wall is preferably essentially flush with the first profile wall of the frame, i.e. the first profile wall and the main portion preferably extend in a common plane.
- The frame construction preferably comprises a further frame, wherein the frame comprises a connection profile and the further frame comprises a further connection profile being designed complementary to the connection profile of the frame, the connection profile and the further connection profile being configured to enter into a preferably positive connection with one another. That is, the frame construction can comprise two frames which preferably in each case comprise a profile as described above. It is also preferred that the frames are connectable to one another by means of their complementary connection profiles. In the event that the frame construction is provided on a suitcase, the suitcase shells are preferably connected with each other by one or more articulated joints such as hinges. By pivoting the suitcase shells about the pivot axis provided by the articulated joints it is possible to open and close the suitcase shells of the suitcase. In the closed position, the complementary designed connection profiles of the frames come into engagement with each other.
- In a further aspect a piece of luggage, preferably a suitcase, with a frame construction as described above is provided, wherein the end portion of the shell is received in the seat of the frame and removably fastened by means of the fastening element being removably inserted in the seat of the frame. Said piece of luggage preferably comprises a frame construction having two frames as described above, wherein each frame comprises a suitcase shell removably fastened by means of a fastening element.
- In a further aspect a method of fastening a shell to a frame construction of a piece of luggage is provided, the method comprises the steps of:
- Providing a piece of luggage with a frame construction as described above;
- Inserting the end portion of the shell into the seat of the profile; and
- Inserting the fastening element in the seat of the profile.

suitcase 1000 comprising twosuitcase shells 100, 100' and aframe construction 10 is shown inFigure 1 . As will be explained in greater detail with reference tofigures 2 to 5 , theframe construction 10 comprises twoframes 1,1' which in each case are connectable to one of thesuitcase shells 100, 100'. Thesuitcase shells 100, 100' can be made of a metal such as aluminium or of a polymeric material, for example polyethylene, polypropylene, acrylonitrile butadiene styrene, polycarbonate or the like. Theframes 1,1' are advantageously made of the same material as thesuitcase shells 100, 100', i.e. they are preferably made from aluminium or plastics. - The
frames 1, 1' are articulately jointed by means ofhinges 11 fixed either to the frame or to the suitcase shells so as to allow the opening and closing of the suitcase. In the present example, two hinges 11 are provided on one of the longitudinal sides of the suitcase. The suitcase is further equipped with closure means (not shown) such as snap fasteners or a zip closure. On the lower transverse side the suitcase has awheel assembly 12, which in the present case consist of fourwheels 121 that are arranged opposite each other in corner areas of the suitcase. On the upper transverse side of the suitcase a pull-out handle 13 is arranged on one of the suitcase shells 100' and ahandgrip 14 is provided on theother suitcase shell 100. For a better understanding thesuitcase shell 100 comprising thehandgrip 14 is called in the following theupper suitcase shell 100 and the suitcase shell 100' comprising the pull-out handle 13 is called the lower suitcase shell, respectively. -
Figures 2 to 4 depict theframes 1, 1' of the upper andlower suitcase shells 100, 100' individually. As becomes evident from these figures, theframes 1, 1' are provided as single piece elements of an essentially rectangular shape and with a profiled structure. That is, theframes 1, 1' in each case comprise aconnection profile 3, 3' serving the purpose of connecting theframes 1,1' with each other, aU-shaped profile 2, 2' serving the purpose of connecting aliner 6 to theframes 1, 1', and ashell profile 4, 4' serving the purpose of connecting thesuitcase shells 100, 100' to theframes 1, 1', respectively. In the connected state, i.e. when the twoconnection profiles 3, 3' are connected with each other and thesuitcase shells 100, 100' are received within the shell profiles 4, 4', the shell profiles 4, 4' and thesuitcase shells 100, 100' face towards an outside of the suitcase. The connection profiles 3, 3' and theU-shaped profiles 2, 2' are facing towards the interior of the suitcase and are offset inwardly with respect to thesuitcase shells 100, 100' and the shell profiles 4, 4'. TheU-shaped profiles 2, 2' and the connection profiles 3, 3' are thereby arranged within a common plane that extends parallel to a plane of thesuitcase shells 100, 100'. - However, it needs to be taken into consideration that the
frames 1, 1' can be provided withoutsuch shell profiles 4, 4' orconnection profiles 3, 3' orU-shaped profiles 2, 2', respectively. For example, theframes 1, 1' could be secured to one another by means of external closure means only such as zip closures or snap fasteners. Likewise, especially if no liner is desired in the suitcase, it is possible to omit theU-shaped profiles 2, 2' from theframes 1, 1'. For the reason of simplicity,figure 5 showsframes 1, 1' in which the U-shaped profiles for connecting a liner are omitted. Similarly, theframes 1, 1' according tofigure 6 are depicted without the shell profiles. Nevertheless it should be noted that any aspects discussed with respect to one of theseframes 1, 1' can be present on theother frames 1, 1'. - As follows from
figures 3 to 6 , the connection profiles 3, 3' are arranged such on theframes 1, 1' that they can be brought into engagement with each other when thesuitcase 1000 is closed. To this end, the lower frame 1' comprises a connection profile 3' which comprises inner andouter surfaces 31', 32' that run towards each other. The inner surface 31' refers to that surface of the connection profile 3' that faces towards an interior space 15' of the frame 1' and theouter surface 32' refers to the surface facing towards an outside of the frame 1', respectively. In the cross-section, the connection profile 3' of the lower frame 1' is essentially in the shape of a "V", wherein the length of the inner surface 31' is greater than the length of theouter surface 32'. Said V-shaped connection profile 3' on the lower frame 1' forms a receptacle for a correspondingly configured profiledstructure 3 on theupper frame 1. That is, theconnection structure 3 on theupper frame 1 is designed so as to be insertable into the receptacle formed by the inner andouter surfaces 31', 32' of the connection profile 3' of the lower frame 1' and has an essentially triangular cross-section. - As best seen in
figure 5 , the triangularly shapedconnection profile 3 on theupper frame 1 has likewise aninner surface 31 facing theinterior space 15 of theframe 1 and having a length that is greater than the length of anouter surface 32 facing towards the outside of theframe 1. When thesuitcase 1000 is in its closed position, the triangularly shapedconnection profile 3 is essentially fully received within the V-shaped connection profile 3' as in the case of a tongue-and-groove connection, wherein the inclination of the respectiveinner surfaces 31, 31' andouter surfaces outer surfaces lower frames 1, 1' is provided which holds the twosuitcase shells 100, 100' closed when the suitcase is in the closed position. - As further follows from
figures 3 to 5 , the shell profiles 4, 4' on the upper andlower frames 1, 1' are of an identical design and in each case are substantially U-shaped when viewed in cross-section. An end portion of thesuitcase shells 101, 101' can be inserted into theU-shaped seat 41, 41' provided in the shell profiles 4, 4'. Different possibilities to secure theend portions 101, 101' of thesuitcase shells 100, 100' into the shell profiles 4, 4' are conceivable. For example, theend portions 101, 101' could be permanently adhered to the shell profiles 4, 4' by e.g. gluing them into theseats 41, 41'. A releasable securing could be achieved by means of a clamping connection, where theend portions 101, 101' have dimensions that approximately correspond to the dimensions of theseats 41, 41'. Or else, the dimensions of theend portions 101, 101' could be smaller than of the clear width theseats 41, 41' and a fastening could be achieved with the aid of anadditional fastening element 42 as shown infigures 5 and11 to 17c . - The shell profiles 4, 4' are thereby arranged on their
respective frame 1, 1' in a mirrored manner with respect to one another. In particular, when thesuitcase shells 100, 100' are inserted into theframes 1,1' and the suitcase is in its closed position, the shell profiles 4, 4' are mirrored with respect to a plane extending perpendicularly to a plane spanned by thesuitcase shells 100, 100' in the region of the shell profiles 4, 4'. Between the upper andlower suitcase shell 100, 100' agap 102 is formed which allows the insertion of a zip closure, for example. Though, as has been mentioned earlier, the connection established between the connection profiles 3, 3' of theframes 1, 1' is already sufficient for a tight closing of the suitcase. Saidgap 102 is caused by the particular design of the connection profiles 3, 3', in particular by theinner surface 31 of the triangularly shapedconnection profile 3 on theupper frame 1 having a length that is greater than the length of the corresponding inner surface 31' of the V-shaped connection profile 3' on the lower frame 1'. - The
U-shaped profiles 2, 2' for connecting aliner 6 to theframes 1, 1' are now discussed in greater detail with respect tofigures 3 ,4 and6 to 10 . As follows from these figures, the upper andlower frames 1, 1' in each case comprise such aU-shaped profile 2, 2'. For reasons of simplicity reference will be made in the following to only one of the frames and thus to only one of the U-shaped profiles for connecting to a liner. However, it should be noted that the following explanations likewise apply to the other frame and its U-shaped profile. - The
U-shaped profile 2, 2' for connecting to aliner 6 has aprofile base 21, 21', afirst profile wall 22, 22' and asecond profile wall 23, 23'. Aseat 28, 28' for aliner 6 is delimited by the opposing firstinner surface 24, 24' of thefirst profile wall 22, 22' and the secondinner surface 25, 25' of thesecond profile wall 23, 23' that face one another. In the embodiment shown, the first andsecond profile walls profile base 21, 21' towards theirfree edge regions second profile walls inner surface 24, 24' is provided with afirst groove 26, 26' and the secondinner surface 25, 25' is provided with asecond groove 27,27', saidgrooves U-shaped profile 2, 2'. Thegrooves U-shaped profile 2, 2' and along a circumferential direction of theframe 1, 1'. In case that thesuitcase shell 100, 100' is in connection with theframe 1, 1', thegrooves suitcase shell 100, 100' in the region of theU-shaped profile 2, 2'. - The
frame construction 10 further comprises astrip 5 which can be received in theU-shaped profile 2, 2' and which has opposinglateral edge regions grooves liner 6 that is inserted into theseat 28, 28' to theframe 1, 1'. Thestrip 5 has an elongate rectangular shape as shown infigure 7 . In order to securely fix theliner 6 to theframe 1, 1' thestrip 5 extends, when inserted into thegrooves frame 1, 1' and circumferentially around theentire frame 1, 1'. Thegrooves strip 5 are dimensioned such that, when thestrip 5 is inserted into thegrooves small gap 211, 211' is formed between thestrip 5 and the first and secondinner surfaces 24, 24' 25.25'. Thegap 211, 211' allows theliner 6 to extend from within theseat 28, 28' of theU-shaped profile 2, 2' laterally around thelateral edge regions strip 5 to the outside of theU-shaped profile 2, 2'. - The dimensions of the
U-shaped profile 2, 2' and thestrip 5 are thereby such that, when saidliner 6 is inserted into theseat 28, 28', thestrip 5 may be clicked or snapped into theU-shaped profile 2, 2' from a transverse direction T running perpendicularly to the longitudinal direction L of theU-shaped profile 2, 2'. In doing so theliner 6 is pressed into the first andsecond grooves strip 5. In addition, the dimensions of theU-shaped profile 2, 2' and thestrip 5 are such that, when theliner 6 is inserted into theseat 28, 28', thestrip 5 may be slid into theU-shaped profile 2, 2' along the longitudinal direction L of theU-shaped profile 2, 2' whilst said 6 liner is likewise pressed into said first andsecond grooves liner 6 is fastened to theU-shaped profile 2, 2' by means of thestrip 5, thelateral edge regions strip 5 press part of theliner 6 into thegrooves seat 28, 28' is between about 1 to 5 millimetres, the distance DG, DG' between thefirst groove 26, 26' and thesecond groove 27, 27' is between about 3 to 6 millimetres, and the cross-section CG of the first andsecond grooves strip 5 is between about 2.5 to 5.5 millimetres and the height HS of thestrip 5 is between about 0.25 and 1.25 millimetres. - In the embodiment shown in
figures 8 to 10 , theliner 6 is a single layer material consisting of a two-piece fabric, wherein a thick andelastic fabric piece 63 is sewed to a thin andinelastic fabric piece 64. As further follows from these figures, oneelongate member 62 in the form of a plastic string is attached to theliner 6, wherein the two pieces of fabric are sewn around thestring 62 such that thestring 62 is received within thefold 61 of theliner 6. Saidfold 61 together with thestring 62 is inserted into theseat 28 of theU-shaped profile 2 such, that the thick andelastic fabric piece 63 extends around the firstlateral edge region 51 of thestrip 5 and the thin andinelastic fabric piece 64 extends around the secondlateral edge region 52 of thestrip 5 once thestrip 5 is inserted into thegrooves U-shaped profile 2. - Although not shown in the figures it is also conceivable to provide two or more such U-shaped profiles on the same frame. Said two or more U-shaped profiles could be arranged one above the other with respect to a direction extending perpendicular to the longitudinal direction. In this way, two or more liners could be connected to the frame.
- It should be noted that the frame construction as described above is not restricted to the suitcase shown in the present figures. Instead, it is conceivable to provide such a frame construction to other types of suitcases, e.g. suitcases without wheels, and in particular to any type of luggage comprising two shells to be interconnected.
- The shell profiles 4, 4' for removably fasten the
shells 100, 100' to theframes 1, 1' are now discussed in greater detail with respect tofigures 3-5 and11-17c . Infigures 1 to 12 theframe construction 10, 10' comprising ashell profile 4, 4' and afastening element 42, 42' according to a first embodiment is shown, whereasfigures 13 to 15 depict a second embodiment andfigures 16 to 17c depict a third embodiment of a frame construction, respectively. The main difference between said embodiments is that theshell 100 and thefastening element fastening element 106 is an integral part of theend portion 101 of theshell 100. Moreover, in the second embodiment the fastening element is provided by means of theelongate member 62 of theliner 6 as described above, whereas thefastening element 42 according to the first embodiment corresponds to an element being designed different from and optionally also provided in addition to theelongate member 62. - The first embodiment will now be explained with respect to
figures 3-5 and11-12 . As best seen infigures 3-5 , thefastening element 42 is formed separately from theframe 1 and from theshell 100. The shell profiles 4, 4' in each case comprise aprofile base 43, 43' and afirst profile wall second profile wall 45, 45', wherein aseat 41, 41' for receiving theend portion 101, 101' of theshell 100, 100' is delimited by opposing first and secondinner surfaces second profile walls shells 100, 100' are inserted in theseats 41, 41' of therespective shell profile 4, 4', saidshells 100, 100' are fastened by means offastening elements 42, 42' which are inserted into theseats 41, 41', namely in each case within aspace 412, 412' formed between theend portion 101, 101' of theshell 100, 100' and the first or thesecond profile wall shell profile 4, 4'. For reasons of simplicity, reference is made in the following to one of the frames and accordingly to one of the shell profiles and fastening elements only. However, any aspects regarding one of the profile shells and fastening elements are equally present on the other profile shell and fastening element, respectively. - In the present case, the fastening element 42' can be seen as a clamping element which is clamped within the space 412' formed between the
profile wall 44', 45' and the shell 100', wherein the fastening element 42', the seat 41' and the end portion 101' of the shell 100' are dimensioned such, that the distance between thefirst profile wall 44' and the second profile 45'wall essentially equals the sum of the thickness of the end portion 101' of the shell 100' and the thickness of the fastening element 42' in the region of insertion of the end portion 101' in the seat 41' of the shell profile 4'. Or, in other words, the fastening element 42' is configured such, that when the end portion 101' of the shell 100' is received in the seat 41', the fastening element 42' may be slid into the shell profile 4' along an extension direction E or may be pushed along a direction TE transverse to said extension direction E into the space 412' formed between the end portion 101' of the shell 100' and thefirst profile wall 44' or the second profile wall 45', respectively, whilst the end portion 101' of theshell 100 is pressed against the second profile wall 45' or against thefirst profile wall 44', respectively. The fastening element 42', and as a result also the end portion 101' of the shell 100', are thereby fastened by means of a friction fit and a positive-locking fit only, i.e. without the need of any additional fastening means such as an adhesive or by sewing, for example. - An additional fixation of the fastening element 42' and the end portion 101' of the shell 100' is achieved by means of retaining structures provided on the fastening element and the profile walls. In fact, the second profile wall 45' and the fastening element 42' comprise mutually interacting retaining structures 413', 414'. Here, the retaining structure of the second profile wall 45' is provided as a lug 414' formed on the
free end 411' of the second profile wall 45', which lug extends from the second inner surface 47' inwards in the direction of the seat 41'. Said lug 414' provides a stop for the retaining structure in the form of a protrusion 413' formed on the fastening element 42', such that a removal of the fastening element 42' being inserted into the shell profile 4' out of the shell profile 4' is made more difficult, e.g. because a greater amount of force is needed for the removal. The fastening element 42' is thus engaged or snapped in the shell profile 4'. Moreover, the fastening element 42' comprises a further retaining structure 415' in the form of a further protrusion, which, when the end portion 101' of the shell 100' is received in the seat 41', presses against the surface 102' of the shell 100' facing said further retaining structure 415', such that an additional fastening of the end portion 101' being received in the seat 41' is effected. As best seen infigures 11 and 12 , the fastening element 42' has an elongate shape with an upper side 418' and a lower side 419', wherein the retaining structures 413', 415' are arranged opposite one another and in each case extend along an entire width WF of the fastening element 42'. Since the further retaining structure 415' is formed on the upper side 419' of the fastening element 412', the fastening element 412' essentially takes the form of an "L". Furthermore, the fastening element 42' extends, when inserted in the seat 41' of the shell profile 4', partially along the extension direction E of the shell profile. In fact, the fastening element 42' has a width WF that is a small fraction of the extension lengths of the first andsecond profile walls 44', 45' along the extension direction E. It is therefore conceivable to provide two or more, in particular a plurality of such fastening elements 42' which can be distributed along said extension direction E around substantially theentire frame 1. However, it is also possible to provide one single fastening element only, in which case said single fastening element preferably has a width that essentially corresponds to the extension lengths of the first and second profile walls along the extension direction E, and as a result, the single fastening element extends along said extension direction E around substantially the entire frame. In the present example, the fastening element 42' is dimensioned such, that a gap 417' is formed between the profile base 43' and the lower side 418' of the fastening element 42' and that the upper side 419' of the fastening element 42' is essentially flush with thefree end 411' of the second profile wall 45' when the fastening element 42' is inserted in the seat 41' of the frame 1'. However, it is likewise conceivable to dimension the fastening element 42' such, that its upper side 419' projects beyond thefree end 411' of the second profile wall 45' when the fastening element 42' is inserted in the seat 41' of the frame 1'. Such a design would facilitate the removal of the fastening element 42' being inserted in the seat 41', since the projecting upper side 419' could be grasped by a tool such as pliers. In addition, the free end region 48' of thefirst profile wall 44' has a retaining structure 416' in the form of a lug extending inwards in the direction of the seat 41', wherein said retaining structure 416', when the end portion 101' of the shell 100' is received in the seat 41', presses against the surface 103' of the shell 100' facing said retaining structure 416' such that an additional fastening of the end portion 101' being received in the seat 41' is effected. - In the region of the seat 41', the first and
second profile walls 44', 45' extend essentially parallel to one another, wherein the second profile wall 45' has a length LP2 which is greater than the length LP1 of thefirst profile wall 44' along the transverse direction TE. In other words, theshell profile 4 has essentially the shape of a "U", wherein the first andsecond profile walls 44', 45' correspond to the side legs of said "U", and wherein the side leg associated with the second profile wall 45' is longer than the side leg associated with thefirst profile wall 44'. Moreover, the region of the second profile wall 45' that is extended with respect to thefirst profile wall 44' is arranged offset with respect to the remaining part of said second profile wall 45'. By means of said offset arrangement as well as the retaining structure 414' in the form of the lug provided at thefree end 411' of the second profile wall 45' a groove 420' is formed, within which groove 420' the retaining structure 413' of the fastening element 42' can be received. The shell 100' in turn has a curvature 104' dividing the shell 100' into the end portion 101' and a main portion 105', whereby the main portion 105' is arranged off-set with respect to the end portion 101', and wherein the length LP2 of the second profile wall 45' essentially equals the overall length of the end portion 101' and the curvature 104' in the transverse direction TE. When the fastening element 42' is inserted in the seat 41' of theframe 1, the second retaining structure 415' of the fastening element 42' presses against the first surface 102' of the shell 100' in the region of the curvature 104'. The curvature 104', in particular its inclination and its longitudinal extension, is selected in this case such, that the main portion 105' is laterally offset with respect to the end portion 101' of the shell 100' and essentially flush with thefirst profile wall 44'. In other words, the main portion 105' of the shell 100' and thefirst profile wall 44' essentially extend in a common plane. - In the following, the second and third embodiment of the frame construction will be described with reference to
figures 13 to 15 andfigures 16 to 17c , respectively. It should be noted that the frame construction in these figures is shown rather schematically. For example, theconnection profile 3, 3' is merely outlined as a recess and theprofile 2, 2' serving the purpose of connecting theliner 6 to theframe 1, 1' is completely omitted. It should be understood that one or both of theseprofiles
As has been mentioned previously, the frame construction according to the second embodiment differs from the frame construction according the first embodiment manly in that the fastening element is provided by means of theelongate member 62 being attached to theliner 6. To this end, thesecond profile wall 45 of theshell profile 4 has arecess 421, into which theelongate member 62 can be received. Therecess 421 is formed in thesecond profile wall 45 such, that theelongate member 62 presses against theshell 100, in particular against thecurvature 104 of theshell 100, and thereby clamps theshell 100 within theshell profile 4. In this case, theelongate member 62 acts as a clamping element which fastens theshell 100 to theframe 1 by means of a friction fit and a positive-locking fit only, i.e. without the need of any additional fastening means such as an adhesive or by sewing. Thus, also the frame construction according to the second embodiment allows a removable fixation of theelongate member 62, and as a consequence of theshell 100, to theframe 1. - The same holds for the frame construction according to the third embodiment. Namely, said frame construction is characterized by a
fastening element 106 being formed integrally on theend portion 101 of theshell 100, wherein thefastening element 106 has the form of a locking tab protruding from theend portion 101 of theshell 100 and being configured to snap into a correspondingly shapedgroove 422 provided within theshell profile 4 of theframe 1. As best seen infigures 17a to 17c , the first andsecond profile walls shell profile 4 delimit a narrow insertion opening and seat, the clear width of which essentially corresponds to the thickness of theshell 100. In order to make it possible to insert theend portion 101 of theshell 100 with its protrudinglocking tab 106 into the seat of theshell profile 4, thelocking tab 106 is configured compressible, preferably spring-elastically. Once theend portion 101 with itslocking tab 106 is inserted in the seat of theshell profile 4, thelocking tab 106 is pushed away from theend portion 101 of theshell 100 and latches in thegroove 422 formed in thesecond profile wall 45 of theshell profile 4. In this manner theshell 100 is removably clamped within theshell profile 4. As can be seen infigure 16 , it is thereby conceivable to provide a plurality ofsuch locking tabs 106 on theshell 100. Hence, the frame construction according to the third embodiment allows a removable fastening of the shell to the frame construction, too.LIST OF REFERENCE SIGNS 1000 suitcase 31, 31' inner surface 100, 100' suitcase shell 32, 32' outer surface 101, 101' end portion 102, 102' first surface 4, 4' shell profile 103, 103' second surface 41, 41' seat 104, 104' curvature 42 fastening element 105, 105' main portion 43, 43' profile base 106, 106' locking tab 44, 44' first profile wall 45, 45' second profile wall 10 frame construction 46, 46' first inner surface 11 hinge 47, 47' second inner surface 12 wheel assembly 48, 48' free end region of first profile wall 121 wheel 13 pull-out handle 49, 49' free end region of second profile wall 14 handgrip 410, 410' free end of first profile wall 1, 1' frame 411, 411' free end of second profile wall 2, 2' U-shaped profile 21, 21' profile base 412, 412' space 22, 22' first profile wall 413, 413' retaining structure of fastening element 23, 23' second profile wall 24, 24' first inner surface 414, 414' retaining structure of second profile wall 25, 25' second inner surface 26, 26' first groove 415, 415' retaining structure of fastening element 27, 27' second groove 28, 28' seat 416, 416' retaining structure of first profile wall 29, 29' free edge region 210, 210' free edge region 417, 417' gap 211, 211' gap 418, 418' lower side of fastening element 3, 3' connection profile element 419, 419' upper side of fastening 64 second liner piece 420, 420' groove 421, 421' recess L longitudinal direction 422, 422' groove T transverse direction D depth 5 strip HS height of strip 51 lateral edge region WS width of strip 52 lateral edge region WU, WU' clear width of seat DG, DG' distance between grooves 6 liner E extension direction 61 fold TE transverse direction 62 elongate member LP1 length of first profile wall 63 first liner piece LP2 length of second profile wall
