[0099] With reference to FIGS. 1, and 2a to 2g, the piece of luggage 1 according to the invention comprises a cavity 10 and a wall, called a support wall 100, against which an object O can be held in a storage position inside the piece of luggage 1.

[0100] The piece of luggage 1 is in particular a suitcase and more specifically an “briefcase”.

[0101] The support wall 100 is rigid and flat.

[0102] To hold an object O against the support wall 100, the piece of luggage 1 according to the invention comprises a holding system comprising at least one strap 20.

[0103] According to the present embodiment illustrated by FIG. 1, the holding system comprises two straps 20.

[0104] The straps 20 extend against the support wall 100 in the absence of stress. More specifically, the straps 20 extend from a first side of the support wall, to a second side of the support wall, opposite the first side.

[0105] As illustrated in FIG. 2a, when the straps 20 are not used to hold an object, they are then pressed against the support wall 100.

[0106] In other words, at rest the straps 20 assume a position pressed against the support wall 100.

[0107] To this end, the straps 20 may be at least partially elastic or the piece of luggage comprises a system for tensioning the straps.

[0108] For example, the straps 20 can be made from an elastic material or have elastic strips.

[0109] These elastic strips can be located at the ends of the straps 20, below the support wall 100 so that the straps 20, in their pressed position or in a position where they are fully extended, still have a visible strip made of a noble material, such as leather, which is inelastic or less elastic than the elastic strips.

[0110] According to another example, a system for tensioning the straps 20 can be in the shape of springs pulling the ends of the straps 20, or else the shape of rollers coupled to springs so that the rollers tend to return the straps in their position pressed against the support wall 100.

[0111] According to the principle of the invention and as illustrated by FIGS. 1, and 2a to 2g, the holding system also comprises: [0112] at least one rail 21; [0113] at least one tightening member 22 slidably mounted on the rail 21.

[0114] The rail 21 is carried by the support wall 100.

[0115] The holding system comprises in particular a rail 21 for each strap 20.

[0116] According to the present embodiment illustrated by FIG. 1, the holding system comprises two straps 20 and two rails 21.

[0117] Each strap 20 extends to cover a rail 21 in the absence of stresses.

[0118] In other words, the holding system comprises a rail 21 underlying each strap 20 coupled to the support wall 100.

[0119] The tightening member 22 is in turn slidably mounted on the rail 21 at least partially covering the strap 20.

[0120] With reference to FIG. 4, the support wall 100 has a recess 1000 inside which the rail 21 is housed.

[0121] As illustrated by FIG. 4, when it is not subjected to external stresses and it is thus pressed against the support wall 100, the strap 20 is then flush with the surface of the support wall 100 directly adjacent to the recess 1000. More specifically, it is an upper face of the strap 20 which is flush with the surface of the directly adjacent support wall 100.

[0122] The strap(s) 20 thus do not protrude from the support wall 100.

[0123] Still according to the principle of the invention, the tightening member 22 is movable between: [0124] an unlocked state in which it can slide freely along the rail 21; [0125] a locked state in which it is immobilized on the rail 21.

[0126] With reference to FIGS. 2a to 2g, for a strap 20, the holding system comprises two tightening members 22.

[0127] With reference to the embodiment illustrated in FIG. 6, the holding system comprises three tightening members 22 for the same strap 20.

[0128] According to the embodiments illustrated by FIGS. 3 to 8b, each tightening member 22 comprises a bar 220 which covers the strap 20.

[0129] This bar 220 has in particular a width sufficient to extend to cover, that is to say above, the width of the strap 20.

[0130] Each tightening member 22 also comprises a base 221 which carries the bar 220 and which slides on the rail 21.

[0131] In the unlocked state of the tightening member 22, the bar 220 is in a low position close to the rail 21.

[0132] In the locked state of the tightening member 22, the bar 220 is in an upper position away from the rail 21 relative to the low position.

[0133] The strap 20 can drive the bar 220 from its low position to its high position.

[0134] Consequently, when the strap 20 assumes a position in which it moves away from the support wall 100 from the rail 21, then it exerts a traction on the bar 220 so that the bar 200 rises from its low position to its high position.

[0135] In other words, the low position of the bar 220 corresponds to a non-pulled state, and the high position of the bar 220 corresponds to a pulled state.

[0136] According to this design, the switching of the bar 220 from its low position (non-pulled state) to its high position (pulled state) causes the tightening member 22 to switch from its unlocked state to its locked state, thus immobilizing the tightening member 22 along the rail 21.

[0137] Conversely, the switching of the bar 220 from its high position (pulled state) to its low position (non-pulled state) causes the tightening member 22 to switch from its locked state to its unlocked state, then releasing the tightening member 22 and allowing it to slide freely along the rail 21.

[0138] Consequently, as illustrated by FIGS. 2a to 2g and as explained precisely below, by placing an object O under the strap 20, against the support wall 100, and by bringing the tightening member 22 closer to the object O, then the strap 20 is stretched away from the rail 21 from the tightening member 22 (due to the presence of the object O), and exerts a traction on the bar 220 allowing it to be switched in its high position (pulled state) and held it in this position.

[0139] The bar 220 thus constitutes an actuator allowing to switch the tightening member 22 from its unlocked state to its locked state, and from its locked state to its unlocked state.

[0140] To switch the tightening member 22 from its locked state to its unlocked state while the strap tends to hold the bar 220 in its high position (pulled state), a user only needs to press the bar 220 to switch it to its low position. The pressure of the user on the bar 220 then counteracts the traction exerted by the strap.

[0141] After the pressure of the user and the switching of the bar 220 in its low position, the user can slide the bar 220 freely along the rail 21, of course by maintaining pressure on the bar 22, so as to loosen the strap 20 around the object O.

[0142] According to the embodiments illustrated by FIGS. 4 to 8b, the base 221 has at least one wheel 5.

[0143] The or each wheel 5 is essentially underlying the bar 220, or located in the immediate vicinity of the bar 220.

[0144] The or each wheel 5 is in contact with the rail in the low position (non-pulled state) of the bar 220, thus allowing to facilitate the sliding of the base 221 along the rail, in particular if a pressure is exerted on the bar 220 to hold it in its low position (non-pulled state).

[0145] FIGS. 3 to 5 illustrate a first embodiment of the invention.

[0146] According to this first embodiment and with reference to FIG. 5, the base 221 extends longitudinally parallel to the rail 21 and has along its length: [0147] a first end portion 31 forming a sliding connection with the rail 21; [0148] a second end portion 32, opposite the first end portion 31, carrying the bar 220, and being at least partially movable in height relative to the rail 21; [0149] a central spacing portion 30 located between the first end portion 31 and the second end portion 32.

[0150] With reference to FIGS. 4 and 5, the first end portion 31 has two surfaces opposite to each other: [0151] a “ventral surface” 310; [0152] a “dorsal surface” 311.

[0153] The ventral surface 310 is in contact with a surface oriented towards the top of the rail 21, and the dorsal surface 311 is in contact with a surface oriented towards the bottom of the rail 21.

[0154] According to the present embodiment and with reference to FIGS. 3 and 4, the base 221 is split into two side portions 221a, 221b symmetrical to each other relative to a longitudinal plane L passing through a central axis of the rail 21, perpendicular to the support wall 100.

[0155] These two side portions 221a, 221b are located on either side of the bar 220.

[0156] The rail 21 has a support strip 210 for the strap 20. This support strip 210 is housed between the two side portions 221a, 221b of the base 221 of the tightening member 22.

[0157] According to this embodiment, each of the two side portions 221a, 221b has, at the first end portion 31, a groove 61.

[0158] These grooves 61 are symmetrical to each other relative to the longitudinal plane L.

[0159] In cooperation with these grooves 61, the rail 21 also has tabs 62 which are complementary to the grooves 61, each tab 62 entering inside one of the grooves 61. The tabs 62 each form a sliding connection with one of the grooves 61.

[0160] In this embodiment, the rail 21 thus has a support strip 210 and two tabs 62 extending on either side of the support strip 210.

[0161] Each of the tabs 62 of the rail 21 then has: [0162] an upwardly oriented surface on which the ventral surface 310 of the first end portion 31 of the base 221 comes into contact, and [0163] a downwardly oriented surface of the rail 21 on which the dorsal surface 311 of the first end portion 31 of the base 221 comes into contact.

[0164] With reference to FIG. 5, the dorsal surface 311 and the ventral surface 310 each have an edge 312a, 312b intended to be brought into the blocking position on the rail 21, and in particular on the tabs 62 of the rail 21, in the high position (pulled state) of the bar 220.

[0165] These edges 312a, 312b are longitudinally offset from each other along the base and more specifically along the first end portion 31. The edge 312a belonging to the dorsal surface 311 is located between the second end portion 32 and the edge 312b belonging to the ventral surface 310.

[0166] According to this embodiment and as illustrated in FIG. 3, if a user: [0167] positions an object O under the strap 20; [0168] brings the tightening member 22 close to the object O, and [0169] releases the pressure he exerts on the bar 220,
then the strap 20 pulls the bar 220 in its high position (pulled state). With reference to FIG. 5, this traction braces the base 221 and causes a blocking of the edges 312a, 312b on the rail 21. The central spacing portion 30 creates a leverage effect which increases the pressure exerted by the edges on the rail 21, thereby increasing the blocking phenomenon.

[0170] FIGS. 6 to 8b illustrate a second embodiment of the invention.

[0171] With reference to these figures, the bar 220 is in the shape of a buckle 2200 through which the strap 20 is intended to be inserted.

[0172] As illustrated in FIGS. 7 and 8b, the tightening member 22 has friction surfaces 40.

[0173] According to the first variant embodiment illustrated by FIGS. 6, 7 and 8b, the friction surfaces 40 are notched and complementary to racks 400 belonging to the rail 21.

[0174] In the high position (pulled state) of the bar 220, the friction surfaces 40 are remote from the rail 21, and in particular from the racks 400.

[0175] In contrast, in the low position (non-pulled state) of the bar 220, the friction surfaces 40 are applied against the rail 21, and in particular the notches of the friction surfaces 40 are anchored in the racks 400.

[0176] According to another variant embodiment not shown, the friction surfaces 40 can be made of a non-slip material.

[0177] With reference to FIGS. 6 to 8b, the base 221 of the tightening member 22 comprises: [0178] a carriage 2210 sliding on the rail 21; [0179] means for transmitting the movement of the bar 220 which is carried by the base 221, which comprises two levers 4 mounted to be movable in rotation on the carriage 2210.

[0180] The buckle 2200 is movable relative to the carriage 2210 using levers 4.

[0181] The levers 4 have the friction surfaces 40, and means for connection to the bar 220. These connection means are in the shape of axis 41.

[0182] These levers 4 allow to move the friction surfaces 40 under the effect of the movement of the buckle 2200.

[0183] More specifically, the base 221, the levers 4 and the buckle 2200 together form a mechanism called a “butterfly mechanism” allowing the rotation of two opposite levers 4 during the vertical translation of the buckle 2200.

[0184] With reference to the embodiment illustrated by FIGS. 6, 8a and 8b, and as for the embodiment described previously illustrated by FIGS. 3 and 4, the rail 21 also has tabs 62 which are complementary to grooves 61.

[0185] Unlike the previous embodiment described, the base 221 has two tabs 62 complementary to two grooves 61 belonging to the rail 21.

[0186] As with the first embodiment, the grooves 61 are symmetrical to each other relative to a longitudinal plane L passing through a central axis of the rail 21 and perpendicular to the support wall 100.

[0187] The tabs 62 in particular belong to the carriage 2210.

[0188] As mentioned above, the base 221 has wheels 5.

[0189] With reference to FIGS. 6 and 7, the wheels 5 are carried by the tabs 62. The wheels 5 are arranged so as to center the tabs 62 inside the grooves 61.

[0190] According to this embodiment, when the user presses on the bar 220, the buckle 2200 is pressed on the carriage 2210. This recess results in the switching of the bar 220 from its high position (FIG. 8a) to its low position (FIG. 8b), or in other words from its pulled state to its non-pulled state.

[0191] This change in position of the bar 220 relative to the carriage 2210 is made possible thanks to the levers 40 which pivot about their axes 41 and which cause the switching of the friction surfaces 40 from their position applied against the rail 21 (FIG. 8a) to their position remote from the rail 21 (FIG. 8b). In other words, there is unspiking of the tightening member 22 from the racks 400 of the rail 21.

[0192] Conversely, if the strap 20 pulls the bar 220, and thus the buckle 2200, in its high position (pulled state), then the friction surfaces 40 spike into the racks 400, thereby immobilizing the tightening member 22 in position along the rail 21.

[0193] With reference to FIGS. 2a to 2g, the operating principle of the holding system of a piece of luggage according to the invention is explained below.

[0194] In FIG. 2a, the strap 20 is pressed against the rail 21, on the support wall 100. The strap 20 then covers the rail 21. Two tightening members 22 are located along the rail 21.

[0195] According to FIG. 2b, a portion of the strap 20 is lifted to slide a first object O between this portion of the strap 20 and the support wall 100.

[0196] As shown in FIG. 2c, the first object O is pressed against the support wall 100 by the portion of the strap 20 previously lifted. This first object O is not, however, yet perfectly held by the strap holding system 20.

[0197] To this end and as illustrated by FIG. 2d, the tightening member 22 was slid in the direction of the object O. This tightening member 22 tightens the strap 20 around the object O by adapting the size of the strap 20 pressing the first object O on the support wall 100. The tightening member 22 also decreases the distance between the portions of the strap which extend from the support wall 100 to surround the first object O. Holding the first object O is thus optimized.

[0198] In order for the tightening member 22 to slide from the position illustrated in FIG. 2d to that illustrated in FIG. 2d, it must be in its unlocked state. As mentioned above, and according to the embodiments illustrated by FIGS. 3 to 8b, a user must press the bar 220 to be able to switch the tightening member 22 in its unlocked state and to be able to slide it.

[0199] Of course, the user must press the bar 220 while sliding it to prevent it from returning to its locked state when it is being translated along the rail 21.

[0200] When the tightening member 22 is in its use position, as illustrated in FIG. 2d, the user then releases the bar 220 which returns to its upper position under the effect of the traction exerted by the strap 20. The tightening member 22 then switches into its locked state and is held in this state under the effect of the tension of the strap 20.

[0201] With reference to FIGS. 2e to 2g, the holding in position of a second object O is achieved in a similar manner to that of the first object O. Thus, a second portion of the strap 20 is spaced from the support wall 100, the second object O is introduced under the strap 20 which is then released. The last tightening member 22 (located on the right in the figures) is finally slid to the second object O to tighten the strap 20. The tension of the strap 20 also holds the bar 220 in its locked state, guaranteeing the correct holding of the second object O.

[0202] According to the principle of the invention, the same movement thus allows to adjust the size of the strap 20 according to the shape of an object to be held in the piece of luggage 1 and to lock the strap in position around the object O.

[0203] The first embodiment illustrated by FIGS. 3, 4 and 5 also has the advantage that any movement of an object O held inside the piece of luggage 1 increases the bracing of the base 221 and therefore the fixing of the tightening member 22.

[0204] The first embodiment also has the advantages of being particularly discreet, compact and light, while being easy to use.
