Description

DESCRIPTION OF THE INVENTION. The present invention relates to suitcases and in particular molded cases of plastic materials. A conventional suitcase of plastic material, comprises two shells or covers each having materials, peripheral forming the side walls, the box of two shells or shells are joined together, by hinges on the back walls and have closures to fix so The edges of the boxes can be removed together when the suitcase is closed. Usually, such boxes have a protruding tongue that runs around the rim of each shell next to the place where the cysts meet to provide - rigidity to the shell that would otherwise be flexible. A metal structure may be included around part or all of the structure to provide additional stiffness. In many box designs, the projecting side also provides the means to grip the lip in the case of opening it, when the shells were loosened, the need to provide a tongue for this purpose, establishes a restriction on the designer of the box. suitcases. According to the present invention, in a first aspect, a suitcase box comprises a base shell and a separating base, each having a circumferential side wall, the side walls form the front and end walls of the box, and the two skins are joined with hinges on the rear wall and have at least one lock for releasably fixing the shells together, when the box is closed, at least one closing portion is mounted on the movable shell and arranged to project away from the peripheral side wall when the closure is released to provide means for gripping and lifting the movable shell and opening the box. With this arrangement, it will no longer be necessary to provide the movable shell with a projecting lip or tongue to grasp when opening the box; In a preferred construction of the box, the edge of the movable shell fits within a channel, at the edge of the base shell, this allows a box with a rounded contour to be constructed. Preferably, the closures are of a traversed fastener construction, designed to pull the two shells together when closed; preferably, the closures fit in a recess in the peripheral wall of the shell so as not to project themselves basically when they are fixed. Two crescents can be mounted on the extreme walls of the box, near the front of the box; Two closures can be provided, one at each end, with this arrangement - the closures are easy to take to open the box. The present invention also concerns the problem of handling heavy boxes, it is known to provide the boxes with wheels to transport them when lying down weighs a lot; In a construction, a pair of wheels are located in the corner of the box, between the rear wall and one of the end walls. Such boxes are intended to be used by inclining them at a certain angle so that the wheels run on the floor, and a control handle can be provided near the opposite front wall-face. Another type of box has four rollers on the back wall of the box, the box rests on the rollers with the front wall facing up and is pulled along the floor by a strap. According to the present invention, a suitcase box, comprising a base shell and a removable or movable shell, each shell having a perennial side wall, the side walls forming the front walls, a carrier handle on the front wall of the box, the - which has two coaxial wheels mounted on the corner of the box, between the rear wall and one of the end walls and two rollers mounted on the rear wall, including when - except one additional handle, for pulling the box on the -wheels and rollers, or to control the box when tilting it on the two wheels, this arrangement of the box, the traveler can roll the box, either on two wheels or four depending on their preference and circumstances. The box may include a control handle at or near the corner of the box or placed diagonally to the wheels. In addition, it can alternatively include a handle for pulling in the same region. The boxes of known construction, usually join together, in their rear walls by a single hinge that passes through holes in hinge joints. Thieves have found it possible to have access to such boxes by pushing the hinge pin even when closed. According to the present invention, in a third embodiment, a suitcase box is provided, comprising a base shell and a lift shell, each shell having a peripheral side wall forming the front walls, the rear front walls and the ends of the front walls. the box, the two -hells being connected to the rear wall by hinges or chameleons and having at least one closure for securing the shells when the suitcase is closed, the hinge means comprise hinge joints. interacoplantes, on - the edges of the rear walls of the respective shells and two hinge pins or hinge inserted from opposite ends through holes aligned in the bearings, there being an obstruction on one side of the shells between the -holes aligned to prevent the pins from being pushed out of the holes through the end where they have been inserted.

With this arrangement, the hinge pins can only be extracted from the ends in which they have been inserted. It is not possible to push the pins out-through the opposite end due to the existing obstruction. It is known to provide the case with a handle to pull the box along the floor when resting, on four wheels or rollers; In a known arrangement, the handle is attached to a retractable strip, the strip is attached to a spring line that extends to the inside of an end wall of the box, and passes over a pulley-about the extreme wall of the box. The length of the strip required to conveniently pull a box is greater the smaller the box, because the front wall of the box is closer to the floor, however, with the linear grip arrangement, the length of the strip that can be accommodated is restricted in small boxes. According to the present invention, in a fourth aspect, a luggage box is provided having upper front bottom walls, four wheels mounted on the rear wall and a handle assembly for pulling near the corner, between the front wall and one of the end walls, the handle assembly comprises a pull strip attached at one end to a reel mounted inside the box, the reel is loaded with a spring, so as to wrap the strip when not in use, the strip passes to the outside of the box through a slot in the wall of the box, and a handle is attached to the outer end of the strip with a recess on the outside of the box in said corner , and the handle is formed to adjust in the recess when it is not - -use. With this arrangement, the length of the strip can be adjusted according to the size of the box, and if desired, the same unit can be used in a wide range of boxes of different sizes. It is desirable, to be able to open the boxes completely to have access and be able to pack the upper part as well as the base; When a box is provided with beavers or rollers, beavers can limit the amplitude at which the box can be opened. According to the present invention, in a fifth aspect, a luggage box or suitcase is provided which comprises a base shell and a movable shell, each case having a peripheral wall, the side walls forming the front, rear and extreme walls of the box, the two shells are joined by hinges in the rear wall and have at least one lock to secure the box when they are closed, and at least two rollers, one of which - they are mounted on each rear wall of each casing, the rollers are spaced different distances from the hinge axis, and there is a recess provided between the roller furthest from the axis and the hinge axis to accommodate - the roller in the other shell when the box is fully opened. When a luggage box is carried on the roof of a car, it may be exposed to the street, in order to provide rigidity, and for other reasons, it may be desirable to form the edge of the base shell, with the -bios or inner and outer tongues, with a channel between them - that receives the edge of the lifting shell; with such -construction, there is the possibility that the rain that falls -in the box can come together in the channel and penetrate the suitcase -damaged its contents. According to the present invention, in a sixth aspect a luggage box comprising a base shell and a lifting shell is provided, the two cassettes being joined together by a hinge, the edge the base cassette, is formed with an inner lip and an outer lip, with a channel between the inner and outer lips, and internal lip-or tongue extends around the entire box, the outer lip extends around the entire box, except in the region of the hinge , the edge of the lifting shell is received in the channel between the inner and outer lips when the box is closed leaving the inner lip higher than the outer around the entire periphery of the box, with this -regulation, if water is collected in the channel, it will spill into the outside of the box before it can flood the inner lip and damage the contents of the box. In many case construction for travel cases, the carrier handle is pivoted to the base shell, so that it can accommodate the movement of the case, when that is carried, the handle of this type also prevents it from being damaged by the use. However, there are situations where it is desirable that the handle can not pivot about a longitudinal axis.; such cases can be very uncomfortable due to the movement of the box, which causes the grip to rotate in the user's hand. According to the present invention, in a seventh aspect, a luggage box comprising a base shell and a lifting shell is provided, the two hulls being joined together by hinges, and there being at least one closure to stop the box together to be closed-and also a carrier handle, which will be fixed to the wall of the box at its ends to not pivot with respect to the box, being at least a portion of the handle -made of a material that allows a twist when the box is firmly by the handle, and the box moves from one side to the other. With this arrangement, the movement from one side to the other - from the box is compressed by the twisting of the handle. In some constructions of the box, it is desired to provide a lock or pin on the front wall of the box, if the handle or handle is fixed, access may be restricted and thus the closure may be difficult to do. . According to the present invention, in an eighth aspect, a luggage box comprising a base shell and a lifting shell is provided, the two peels are so joined together and there is a handle and a closure to join the shells together when the box is tightened. The closure is located between the gripping portion of the handle and the wall of the box, and is the type that pulls the edges of the shells together when tightening the closure is mounted on one of the shells and has a hook for coupling with a part of the other shell, the closure or lath includes an operating lever coupled to the hook-claw portion by a joint, which when operating the lever to fix the box, causes the The first claw is moved towards the wall of the other clamp, and then it is pulled towards the first clamp, with this arrangement the closing operation is facilitated. In some cases it is desired to be able to divide the space between the lifting shell and the base shell, with a panel, such panels are usually hinged to the back wall of the box and have handles to fix the front edge of the box to the shell or lifting part. A conventional handle shape consists of a tourniquet; Such arrangements, however, are difficult to operate, particularly when one-hand operation is required. According to the present invention, in a -noveno, aspect, a luggage box comprising a base shell and a lifting shell is provided, the two -hells being hingedly joined together along a rear wall of the vehicle. box, and a panel inside the box to divide the space within the lifting shell of the space inside the base shell, the panel is attached at its rear edge to the interior of the rear wall, and has means for fixing -de removably its front edge to the lifting part of the box, the middle comprises a loop or loop attached to the cushion and a hook attached to the inside of the lifting shell an elastic is in position to prevent the loop from disengaging accidentally copy the hook. An embodiment of the invention will now be described, by way of example with reference to the accompanying drawings, in which: Figure 1 shows a perspective view of a box according to the invention; Figure 2 shows a planar top view of the box; Figure 3 shows an extreme elevation of the box; Figure 4 shows a rear elevation of the box; Figure 5 shows a perspective diagram of the box in an open condition; Figure 6 shows a lateral elevation partially - in section of a lateral closure of the box; Figure 7 shows a rear elevation of the closure of Fig. 6; Figure 8 shows a detail of the wall construction; Figure 9 shows a detail of the hinge construction; Figure 10 shows a schematic of the box used in the operation with two wheels; Figure 11 shows a detail of the box used in - operation with four wheels; Figure 12 shows a perspective diagram of the construction of the pull handle; Figure 13 shows a detailed view of the box in the open condition; Figure 14 shows another detail of the box in the open condition; Figure 15 shows a diagram of the rollers in the open condition; Figure 16 shows a cross section through a ring or frame of the box; Figure 17 shows a cross section through the hoop of the box in the region of the hinge; Figure 18 shows a detail of the construction of the handle; Figure 19 shows a side elevational view of the central closure with the wall of the box in transverse section; Figure 20 shows a perspective view of a central cork; Figure 21 shows a perspective detail of an arrangement for holding a divider panel; Fig. 22 is a sectional view taken away from the grip of Fig. 21; Figure 23 shows elevational view of the grip of - Figs. 21 and 22. Referring to the drawings, there is shown a -package 10, comprising two parts or shells, one lift -11, and another base shell 12, each formed as an isolated molding from plastic material, each shell having a wall -peripheral 13 and 14, respectively, and the two shells together form the front 14, the back 15, the upper part 16, the lower part 17, and the end walls 18 and 19, of the box. The edge of the base shell has a thicker section than the rest of the base shell to form an integral frame that runs entirely around the base shell. A carrier handle 21 is mounted on the frame 20 on the front wall of the box; the two faces 11 and 12, are connected together in the rear wall 15, by means of a hinge 22. The edges of the two parts, compartments or shells are held together when the case is closed - by means of of three closures, the two lateral closures 23 and 24 - are mounted on the lifting shell 11, and placed near the end walls. In the modality they are shown near the front of the box between the central point of the extreme sparedes and the front wall. A third closure 25 is mounted on the base shell on the front wall 14, below the grip portion of the handle 21. The three closures are of the type that pulls the edges of the box together with an engaging action of the catch. seen when they squeeze. Referring now to Figs. 6 and 7, the construction of the lateral closures will be described in detail. The side closure 23 comprises a mounting portion 30, a body part 31, and a closing part - 33. Mounting portion 30, is fixed to the wall of the lifting shell 11, by screws 34, which pass through the wall entering the mounting portion. The base part -31, is pivotally connected to the mounting portion 30, by a hinge pin 35, which passes through aligned holes, -in the tabs 36, 37, on the mounting portion and the base portion. , respectively. A spring 38 acts between the mounting portion and the base portion to guide the base portion so that its lower end is forced away from the end wall of the base shell. Part of the body part is projected - upward of the hinge pin 35, to form a stop 39, which couples with part of the mounting portion to limit the movement of the lower end of the body portion away from the box when in the open position shown in FIG. 6. The hinge pin 35 extends generally parallel to the end wall of the box and the edge of the shell. The closure portion 33 is connected to the portion or part of the body 31, near its lower end by a hinge pin 40, with which it passes through holes aligned in tongues or flanges 41, and 42, on the body portion, and the closing portion, respectively. The pivot pin 40 is parallel in its placement to the pivot pin 35.

The main portion of the closure projects upwards from the hinge pin 40 and is formed between upper ends with a stop portion 44, which cooperates with a recess 45 formed by a lip on the outside of the end wall of the hinge. base shell 12. The closure portion pivots about the pin 40 between an open position in which it is inclined upwardly away from the body portion 31 and towards the wall of the box and a closed position in which it projects upwards and it is next to the body portion. The flanges 41 and 42 on the closure portion and the body position resiliently abut one another to provide a frictional resistance to the rotation of the closure relative to the body. A gripping mechanism 50 is located at the lower end of the closure to stop the closure in the closed position. The grip or retainer 50 is slidably mounted in the position of the closure and is guided downwardly by a spring 51 to the hinges 52 carried by the sliding portion engage in recesses 53 in the body to stop the closure portion in the closed position. To release at closure a grip portion 54 at the lower end of the retainer 50 is pushed up against the spring 51 to move the hinges 52 out of the recesses 53 and allow the closure to rotate from the closed position to the open position. The lower portion 55 of the closure forms the part that is taken by the user when opening the box or suitcase. The pivot pin 40 is located closer to the wall of the box than the grip portion 55 so that when the retainer 50 is released, the upward pressure on the portion 55 tends to rotate to the closure from the closed position to the open This rotation is further facilitated by the guiding action of the spring 38 by moving the body portion within the open position, while the stop 44 engages in the recess 45 under the lip at the edge of the box. Once the closure is in the fully open position as illustrated in Figure 6 the stop 44 separates from the lip so that the lid or lifting part can be lifted and the case opened. It will be noted that the position of the body forms an angle of less than 40 °, approximately 20B, in the open position so that the closures point upwards and outwards when released. The lower end of the closures 23 and 24 can be gripped by the user and provide a convenient means to open the case or suitcase. This is particularly important with a box like the one shown in the drawings, where the edge of the cap shell fits within the edge of the base shell and there is no flange or other projection that can be gripped to stop the shell or cover. It should also be noted that the weight of the lid is transmitted through the body portion to the gripping portion of the closure part and that the delicate parts of the retainer do not transmit those forces. To close the box when the lid is capped, the lower end of the closure is pushed inward against the action of the spring 38 so that the stop 44 and the recess 45 move from a position within the plane connecting the pins 35 and 40 to a position just outside this plane, so that the closure closes with a traversing action of the sear. Figure 9 of the drawings shows the details of the construction of the hinge. The hinge is formed by articulations 60 and 61 molded at the edges of the lid part and the base part 11 and 12 respectively, the joints are interengaged and the pins 63 and 64 are inserted from opposite ends into aligned holes 65a and 65b which pass through the hinge joints. The aligned holes do not pass through all the hinge joints. One of the joints 66 does not have a hole through it, forming an obstruction. The pins therefore can not be pushed from the outer ends beyond the obstruction 66. A problem with a conventional box having a single hinge pin that runs the length of the back wall of the suitcase is that a thief sometimes You can have access to the suitcase even when the suitcase is closed by pushing the pin out of the holes in the hinge joints. By including obstruction 66, the pins can not be removed in this way since they can only be removed by removing them from the exteriors for which they have been inserted. The pins 63 and 64 are of such length that when the projecting amount is completely inserted beyond the end of the joints it is insufficient to grip and remove the pins from the hinge. The case 10 is provided with two wheels mounted on shafts in the corner of the case between the end wall 19 and the rear wall 15. The rotational axis of the wheels 71 and 72 are coaxial to each other. On the rear axle of the box near the end wall 18 two rollers 72 and 73 are mounted. The rollers are mounted for a rotary movement about the axes that are vertical when the box is stopped with its rear wall near the ground.

On the end wall of the box is mounted a folding pull handle 74. As shown in Figure 1, the handle can be folded into a hidden position in which it is located in a recess 75 in the end wall of the box. The handle 74 can pivot outward in an extended position as indicated in the diagram of Figure 10 to form a pull or pull handle allowing the box or suitcase to tilt when moving on the two wheels 70 and 71. In the corner of the front wall 14 and the end wall 18 there is a pull back handle 76. The retractable pull handle can be extended as shown in the diagram of Figure 11, to allow the box to be pulled along the 1 floor being on the two wheels 70 and 71 and the two rollers 72 and 73. Thus the box or suitcase can be maneuvered either on two wheels or on four wheels depending on the preference of the user and the circumstances. As can be seen in Figure 3, the top wall 14 of the box diverges from the bottom wall 17 from the front wall backwards to give the box or melta a wedge-shaped appearance when seen from the ends, as can be seen in Figure 1 and 4 the walls of the shells or elevating base portions are countersinked outward in region 80 around rollers 70 and 73. These features allow wheels 70 and 71 and beavers 72 and 73 to be spaced as close as possible to the upper and lower walls. of the box giving it greater stability than it would be the case. Figure 12 shows in diagrammatic form the construction of the pull handle 76. A strip 90 is attached to one end on a reel 91 located in a closure 92 on the inside of the box at the corner between the end wall 18 and the wall front 16. The strip 90 passes through a recess 93 in the wall of the box and is attached to a handle grip 94 on the outer side of the box. A spring 96 operates between the drum 91 and the closure 92 to urge the drum to rotate in a direction by winding the strip 90 when it is not in use. A recess 97 is formed in the structure 20 on the outside of the box at the corner between the front wall 14 and the end wall 18. The recess is elongated along the direction of the structure and curves around the corner . The handle 94 is similarly elongated and curved to fit in the recess 97. When the pull handle is not in use the spring 96 causes the band to wrap on the reel 91 and the handle grip 94 fits in the recess 97 so as not to project from the general outer line of the suitcase or box. The handle 94 has a shorter length than the recess 97 to provide a space 98 within which the user can insert a finger to lift the handle out of the recess when he wishes to use the handle or pull handle. As illustrated in Figure 12, the pull handle assembly is located in the enclosure 92 on the inner side of the base part near the edge of that part or shell. This forms a space between the enclosure or housing 92 and the lower wall 17 of the box where a security box 98 is placed to insert valuables such as keys. The box 98 is molded from a plastic material and has a cover 99 which is connected to the main portion of the box by an integral hinge. When locating the safe in this position it becomes less visible when the suitcase is opened and uses a space that we can call redundant. By providing an arrangement in which the pull strip is entangled on a drum rather than as in the known arrangement in which it passes under the inner side of the end wall of the box on a pole towards a spring lines, the handle of Pulling is more compact and the same unit can be used for different suitcase sizes. The size of the suitcase required will be greater the smaller the size of the suitcase because the front wall will be closer to the ground when pulled. With the linear arrangement, the space available in a small suitcase may not be sufficient to accommodate a convenient length of the pull strip. The construction described avoids this difficulty. The construction of the rollers and the wheels will now be described in greater detail. As can be seen in Figure 4 the base shell 12 is deeper than the shell or lid 11 so that the wheels 71 on the base are more distant from the hinge access 100 than the wheels 70 on the lid and the rhodium 73 on the base also is of the hinged access that the roller 72 in the lifting or lid casing. A recess 101 is formed on the outer side of the rear wall of the base adjacent to the wheels 71, between it and the hinge axis 100. Similarly, a recess 102 is formed on the outer side of the rear wall of the base shell adjacent the roll 73 between it and the hinge axis 100. Recesses 101 and 102 accommodate the wheel 70. and to roll 72 when the box is fully open as shown in Figures 13 and 14. Each roll 72 and 73 is constructed with a portion 110 that swirls around the shaft 111 and carries the roller wheel 112 on a wheel hub 113. The swirling portion includes a portion of shroud 114 that extends downwardly around the roller wheel to protect it from damage by objects on the ground. The wheel shaft 113 of the roller is replaced of the swirl axis in a conventional manner so that the weight of the wheel tends to cause the roller to assume the weight of the wheel tends to cause the roller to take a particular orientation with the wheel down of the swirling shaft when the suitcase is placed with its bottom wall on the floor. As can be seen from the drawings, the swirl portion of the roller is cut by a recess 115 on the side opposite the roller wheels. As a consequence, the swirling portion has an asymmetry around the swirl axis and the center of gravity of the swirling portion is displaced from the shaft in the same direction as the roller wheel axis travels. This displacement of the center of gravity of the swirling portion improves the tendency of the rollers to orient themselves with their axis below the swirl axis when the case is horizontal.

It should be noted that the recess 102 would not be large enough to accommodate the roller when the case is open, if the swirl portion did not include the recess 115. By providing the recess 115 in the castor wheel or roller 73 on the base part, the swirl portion provides for the wheel 112 of the roller 72 in the lid part or shell, when the suitcase is fully opened. The recess 115 extends from the side that is higher when the suitcase opens around the swirling portion to the sides that it measures horizontally. With this arrangement a separation is provided even if the rollers do not fully rotate to the position where the wheel is immediately below the axis of rotation or swirl, for example if there is any blockage in the action or if the suitcase is not on a true horizontal surface . Figures 16 and 17 show the edge construction of the suitcase. As can be seen in Figure 16 the base shell is formed on its edge with an inner lip 120 and an outer lip 121, a channel 122 is formed between the inner and outer lips. The channel 122 accommodates the edge 123 of the shell or lid part when the suitcase or box is closed and gives it rigidity and security with respect to objects that fall to it. The edge construction in the box is basically as shown in Figure 16 around the periphery of the suitcase except in the region of the hinge. Figure 17 shows the construction of this region. The outer side 121 is replaced by the articulations 60 of the base part. Around the periphery the inner lip 120 enters from the suitcase is higher than the outer lip 121. In use if the suitcase is exposed to rain for example when mounted on the roof basket of a car the water can run on the outside of the elevable part or lid and collect in the channel 122. Making sure that the inner lip 120 is at all points higher than the lip 121 the construction ensures that the water collected in the channel is spilled outside before reach a level where it can spill into the inside of the suitcase. Thus the suitcase can be constructed without an erotic seal in the channel to prevent the entry of water. Figure 18 shows details of the construction of the carrier handle 21, it comprises a grip portion 140 made of a material that is sufficiently stiff and rigid to self-support and support the weight of the suitcase, but which allows for a twist. A suitable material is a thermoplastic rubber. The molded grip is fixed to the structure portion 20 of the base wall of the case by means of a U-shaped bracket 141 mounted on the front wall of the case. The pins 143 pass through L-shaped recesses 142 in the members 144 of the U-shaped brackets and through the ends of the handle 140 to fix the handle to the structure. The pin and recess arrangement allows limited movement of the ends of the handle with respect to the structure in the longitudinal direction of the handle. This is fixed to the box or suitcase so as not to allow a pivoting movement about an axis parallel to the longitudinal direction of the handle. However, by using a thermoplastic rubber or similar material for the handle that allows limited twisting movement, the handle can perform a rotational movement of the suitcase when the suitcase is carried without the grip portion rotating in the user's hand. Therefore, the construction of the handle makes the box more comfortable to carry it than it would be if the handle were made of a non-flexible rigid material. As previously indicated, the central lock 25 is located below the handle between the grip portion and the suitcase wall. When the handle is fixed and does not pivot around a longitudinal axis at the points where the box is fixed, access to the central axis is restricted. The central lock is built to facilitate the operation in this restricted space. Figures 19 and 20 show the construction of the central closure in detail. The central closure comprises a base portion 160 which is fixed in a recess 161 on the outside of the base shell of the box on the front wall below the handle. A finger portion 162 is pivotally connected to the base portion by pins 163 that fit in elongated recesses 164 on side flanges 165 of the base portion. The nail portion 162 is also attached to the base portion by pins 166 having a common axis parallel to the pins 163 and mounted on lugs 167 in the nail portion. The pins 166 project into the L-shaped recess 168 in the side flanges the main portion 158 extends parallel to the recess 164. At the end of the recess 168 closest to the edge of the box or suitcase there is a path extension side 169 the extension extends away from the wall of the box approximately at right angles to the main portion of the notch. The pins 163 and 166 cooperate with the recesses 168 and 164 to guide the nail portion between the closed and open position of the closure.

When the closure is open, the pin 183 is at the upper end of the recess 164 as close as possible to the edge of the box. The pin 166 is in the portion of the recess 169. Thus, the hook portion 170 of the nail tilts away from the edge of the box. When the finger portion is pushed down the pin 166 moves to the main portion to the notch causing the finger portion to pivot about the pins 163 and the hook portion 170 to move toward the wall of the shell or part of the finger. cap and engage in a recess 171. Further movement of the nail portion downward causes the pin 166 to move down towards the recess 168 and the pin 166 to the recess 164, so that a translational movement of the position is achieved. of the nail towards the base shell without substantial rotation of the nail portion around the pivot pin 163. The lid or lift shell is then pulled towards the base part when the box is closed. The movement of the described nail portion is effected by means of an operating lever 180 which is pivoted at the base portion by a pivot 181 which passes through lugs 182 on the functional lever and through the side flanges 165 of the base portion . The pivot is parallel to the pins 163 and 166. The lever 180 includes a grip portion 183 that is accommodated in a removed portion 184 at the nail portion 162. A rod 185 passes through the ears 162 on the underside of the nose. the lever and carries on its internal ends, two rollers 186 that engage on the cam surface 187 on the nail portion. A spring 189 acts between the base portion and the lever 180 to guide it so that the pin 181 pivots away from the wall of the box. To close the closure, the user presses the grip portion 183 towards the wall of the box and the lever pivots from the spring action 189 towards the base position. The movement of the levers causes the rollers 184 in engagement with the cam surfaces 187 to oscillate in an arc towards the base and run down the cam surface. These are shaped so that the ends closest to the base part are closer to the edge of the box than the portions furthest from the wall of the box. Consequently when the rollers go down the cam surface 187, the nail portion is pulled down causing them to execute a rotational movement around the pins or pivots 163 and then a translation movement joining the two shells or parts together. A retainer 190 is provided at the lower end of the gripping portion of the lever 180 which functions in a manner similar to the retainer 50 of the closures 23 and 24 to maintain the lever in the closed position. To release the closure and open the case or box, first the retainer 190 is released and the lever 180 is pulled outward, with the help of the spring 189 to allow the nail to move upwards by loosening the squeezing pressure on the two shells and then rotate outwards lifting the hook portion 170 out of the recess 171. It will be appreciated that the closure construction allows the closure to be secured and released in the confined region of the handle 21. Figure 5 shows a panel 200 that divides the space between the lid shell 11 from the space within the base shell 12. The panel 200 has a hinge at its rear edge 201 that attaches it to the inner lip of the rear wall of the box. At both ends of the front edge of the panel 200 there is a loop 202 or ring formed by the molding of a plastic. This includes a bar portion 205 connected to the panel by two strip portions 206 at each end. On the inner side of the shell or lifting part near the corners between the front wall and the existing end or side walls lugs 210 cooperating with the rims 202. Each lug comprises a base portion 220 that is fixed to the lifting lug by screws 221. A bracket portion hook 222 is supported by the base portion. The bar 205 of the loop portion can be hooked through the hook portion 202 to secure the front edge of the panel 200 to the lifting shell. An elastic fastener 223 extends within the inlet or facepiece 224 of the hook portion to prevent the bar from accidentally coming off the hook. The sear comprises a tongue carried by an elastic bracket 225. The tongue forms a constriction or tightening at the entrance or mouth to the inlet. The resilience of the bracket 225 causes the tongue to engage the rear part of the bracket 222. A grip portion 222 is formed on the bracket 225. To further tighten the inlet of the inlet and allow the loop to be removed from the bracket. hook 222, the user presses on the grasping portion 222 against the elastic action of the bracket 225. The base portion of the grip is formed with projecting portions or cheeks 228 on either side of the bracket 225 projecting as far as the grip portion. 226 to prevent the contents of the box or suitcase from depressing the grip portion and thus accidentally loosening the loop from the hook. The grip 220 may be formed from a single mold or from a two-piece molding as illustrated in Figure 23. The construction of the detent mechanism described above allows the panel to be attached to the top or lifting shell or removed using a single manual operation. It will be appreciated that the suitcase described above has several novel features that can be used together or separately in different embodiments.
