Definitions

• This invention relates to luggage cases such as business or attache cases. More particularly, the invention relates to cases having two main compartments for carrying and, in some cases, organizing the contained personal and business related items, the compartments being separated from one another by an internal, hinged, divider panel.
• Such cases fall in generally two groups: the first are softside cases made of fabric or leather-like material, often unstructured in a generally large envelope shape.
• the other general class of cases includes hard outer structure or covering divided into a lid shell and a base shell which are hinged together along the bottom side.
• the base shell usually has a handle attached to the top face for carrying.
• the lid shell and base shell are normally selectively held closed together with a latching device.
• a portfolio section comprising a number of vertically arranged flexible dividers which are attached to a divider panel hinged along the bottom inside edge of the lid shell.
• the entire portfolio construction is held on left and rights sides by flexible gusset panels which permit the divider panel and the intermediate dividers behind the divider panel to hinge out.
• the base shell generally provides a large compartment for carrying clothing items or stacks of papers, books and other items.
• An example of such a brief case is shown in U.S. patent 3,756,639 assigned to the assignee of the present invention.
• the case includes a gravity responsive detent 41 which prevents the operation of the latch lever 17 if one tried to open the case upside-down. This prevents the papers held in the main shell from spilling out as is shown in figure 2 of that patent.
• U.S. patent 4,714,286 to Yamamoto also assigned to the assignee of the present invention, shows an attache case with another gravity sensing feature.
• Yamamoto teaches providing gravity sensing means to control the extent of opening of the lid shell.
• the ball bearing detent located in a slot in the lid stays would permit the case to open fully.
• the ball would fall into a slot to in effect shorten one arm of the stay.
• the lid shell would be prevented from opening fully, thus contents in the main shell of the case wold not tend to fall from the case.
• contents in the main shell of the case wold not tend to fall from the case.
• it's likely that at least some of the contents of the main shell would fall to the bottom of the case even if such contents were prevented from falling completely out of the case. It would be difficult to shut the lid because of the accumulation of contents (papers, pencils, tape recorder, etc.) in the bottom of the case while the lid was even only partially opened.
• none these prior art cases include means for automatically permitting access to either the contents of the portfolio portion while holding the contents of the main portion of the attache case from spilling out of the case or from moving to the bottom of the case.
• any of the above prior art cases provide means for automatically permitting access to the portfolio portion of the case when the case is opened from a vertical orientation and for permitting access to the contents in the base shell of the case when the case is opened from a horizontal position.
• Applicant has invented a case comprising a base shell and a lid shell and a portfolio section normally carried in the lid shell, the portfolio comprising a front panel, hinged along a bottom edge thereof, and means for holding the front panel in an open or a closed position relative to the lid shell, and flexible gussets attaching the sides of the front panel and the sides of the lid shell.
• the lid shell has a height dimension, the front panel of the portfolio extending only part of said height from the hinged side of the shell toward the upper edge of the shell.
• This means for fastening comprises a protrusion means located on the front panel of the portfolio, a first means for releasably holding the protrusion carried by the base shell, and a second means carried by the lid shell for releasably holding the protrusion means.
• a case which has a lid shell and a base shell and means for selectively holding the lid shell and base shell together in the form of a latch, the lid shell being hinged to the base shell and the lid shell defining a lid compartment and the base shell defining a main compartment.
• a first means is provided for automatically holding this panel in a first position wherein the panel closes off the main compartment when the case is opened from a generally vertical position.
• This means also automatically holds the panel in a second position wherein the panel closes off the lid compartment when the case is opened from a substantially horizontal position.
• a case which includes a lid shell, a base shell, a hinge along an adjoining edge of these shells, and means for selectively holding the lid shell and base shell together to shut the case.
• the lid shell defines a lid compartment and the base shell defines a main packing compartment.
• This portfolio includes a panel defining the front of the portfolio and bellows gussets extending between the sides of this panel and the interior of the lid shell.
• Means are provided for holding this panel in alternate positions, this means being operable to either hold the panel in the first position within the lid shell or in the second position in the base shell, this selective positioning being operable while the lid shell and base shell are in the closed position.
• This means for operating comprises a first hook pivoted to the lid shell, this hook including a pendulum portion for sensing the direction of the pull of gravity to position the hook for engaging the front panel when the case is in a horizontal position and for releasing the panel when the case is in a vertical position, said means further including a second hook positioned and carried by the base shell.
• This second hook includes a pendulum means for sensing the direction of gravity and for positioning the hook for engaging the panel when the case is in the vertical position, but for releasing the panel when the case is in the horizontal position.
• This first and second hook means are positioned relative to one another to engage one another when the case is in a vertical position. More particularly, this second hook includes a leg means which forces the first hook out of engagement with said panel when the second hook rotates in response to gravity when the case is a vertical position.
• Figure 1 shows an attache case according to the instant invention in an open position
• Figure 2 shows a broken away portion of the case of Figure 1 with the lid shell being opened from the horizontal position.
• Figure 3 shows the case of Figure 1 after it has been opened in the vertical position.
• Figure 4 is a partially broken away view of a detail of the attache case of Figure 1.
• Figure 5 is a view similar to Figure 4 but showing the case after it has opened in the vertical position.
• Attache case 10 has an overall shape and construction similar to prior art attache cases. As with such prior art cases, it includes a lid shell 11 which defines a lid compartment 12 defined by the space contained within the lid shell. The case further includes a base shell similar in construction to the lid shell 11. This base shell 14 defines a volume which comprises the main compartment 17, which typically is larger than the lid compartment 12. The lid shell 11 and base shell 14 are hinged together along their lower adjoining edges at 24 in a known manner. The lid shell and base shell are selectively held together by latch hooks 18 which are selectively received in latch hook receivers 19 in the base shell. The latch hooks 18 are operated by pivotally mounted latch lever 16 which rotates the hooks away from hooking engagement in receivers 19. This latching mechanism could include a locking device such as an ordinary key lock or perhaps a combination lock, as is well known in the luggage arts.
• the base shell includes a carrying handle 21, here shown as being inset in a cavity along the top side of the base shell.
• a more conventional handle arrangement with the handle or shoulder strap attached to a surface on the top side of the base shell is also contemplated.
• the lid shell compartment is primarily occupied by a portfolio 20 which comprises a divider panel 22 of a generally thin but rigid, aesthetically pleasing material, and bellows gussets 23 made of a flexible cloth, leather,3 or leather-like material.
• These bellows gussets have a generally triangular overall shape which permits the panel 22 to pivot about its lower edge at the lower side of the lid shell in the lid compartment to display the contents thereof.
• hinge stay 25 To either side of the portfolio is a hinge stay 25 of known construction. This limits the range of pivoting of the lid shell 11 about hinge 24.
• a pair of rod members 36 and 36 are attached along the upper horizontal edge of the panel 22. These rod members 36 form corresponding protruding ends beyond the sides thereof.
• the upper edge of the panel 22 defines the height of the portfolio which is substantially less than the overall height of the lid shell 11 and the lid compartment 12 defined therein.
• Within the space between the upper edge of the panel 22 and the upper edge of the shell compartment are one or more lid containers 13.
• These lid containers can take many forms such as zippered pouches made of leather or fabric, but in the preferred embodiment they are defined by boxes with simple spring-loaded, hinged doors which hinge about their lower edges to permit access to the compartment 13 defined therein. The importance of this novel arrangement will be set forth below.
• the main compartment 17 includes one or more base containers 15.
• these containers can take many forms but are shown as being defined by a generally box-like construction with hinged lids which pivot about their lowermost edges (when the case is the vertical position).
• the significance of these compartments or containers and their position within the base shell will be set forth with greater detail.
• the panel 22 is held in the position shown in Figure 1 by a pair of portfolio catches 30 which engage the protruding ends of at least one of the rods 36.
• the catch 30 comprises a box 31 which holds a first pivoting member 32 for relatively free pivotal movement about the axis shown.
• This first pivoting member includes a first hook 32a which can selectively engage the rod member 36 as shown.
• the first pivoting member 32 further includes a pendulum portion 33 which responds to the pull of gravity. In the position shown in Figure 2, pendulum member 33 applies a counterclockwise rotating torque about the axis to place the hook member 32a in firm engagement with the protruding end of rod 36.
• a second box 38 is constructed similar to box 31 and positioned directly opposite thereof within the base compartment 17 and attached to the interior side walls of the base shell 14.
• the first box and second box may include mating surfaces 35 to help align these boxes and the members contained therein relative to one another when the lid shell and base shell are closed on one another.
• a second pivoting member 34 is pivoted for free rotation to the inside of the second box 38.
• This second pivoting member has a second hook 34a which is integral with a second pendulum portion 39 which also responds to the pull of gravity by orienting itself with gravity.
• a protruding arm 40 forms part of the pendulum portion 39. As will be set forth, this protruding arm 40 can engage and, through the force of gravity on the pendulum member 34, rotate the first pivoting member 32 under certain conditions.
• the second box 38 includes semi-cylindrical indentations to receive and precisely position the rod members 36 when the lid shell and base shell are closed on to one another.
• the panel 22 is held in a closed position by the hook portion 32a of first pivoting member 32.
• the portfolio catch 30, and its corresponding mate 30 on the other side of the case can be manually released from the portfolio when the case is positioned in Figure 1 to permit access to the contents of the portfolio.
• the contents of the lid containers 13 and the base containers 15 can be easily had by flipping their doors open using the finger holes shown.
• the first and second pivoting members engage in one another to simultaneously cause the first rotating member 32 to release its hooked engagement from the end of the rod member 36 and to place the second hook member 34a into an engaging relationship with second rod member 36.
• the second pivoting member 34 has moved relative to the case in a clockwise direction.
• the mating surfaces 35 of the first and second boxes have positioned all the parts relative to one another precisely and the semi-cylindrical cutouts on the front face of the second box 38 have held both rods 36 and 36 in precise alignment with the various hook portions.
• the second pivoting member 34 has rotated to bring the protruding arm 40 to engage the pendulum portion 33 of the first pivoting member 32. While the pendulum member 33 would tend to remain in the position shown in Figure 2, it is overpowered by the greater mass of member 34 when the protruding arm 40 engages it. Thus, the first hook 32a disengages from the end of rod 36. If the case is opened from this vertical position wherein the second pivoting member 34 and its corresponding hook 34a have engaged the rod 36, the configuration in Figure 5 will occur. In particular, the panel 22 is held by the second pivoting member 34 to close off most if not all of the base compartment 17 in the base shell 14.
• the bellows gussets 23 are pulled into their open position to expose the contents of the portfolio 20.
• the gussets 23 are sized to permit the lid shell to open a substantial but limited degree.
• the degree to which the lid shell pivots open from this vertical orientation is limited by the bellows sides and not by the stays 25. i this manner, the contents of the main compartment 17 are held in position, making it unlikely that the contents will spill down and prevent the case from shutting completely again.
• access to the contents of the portfolio has been made very convenient with the various sections of the portfolio arrayed for access by the user from the top of the case.
• the contents of lid containers 13 and the base containers 15 are readily accessible now since these containers are located along the upper edge of the lid and base shells flanking the open and arrayed contents of the portfolio section.
• the disclosed attache case has been made to be responsive automatically and immediately to the differing needs of the user, depending on whether the case is opened from the horizontal position or whether the case is opened from the vertical position.
• This novel functioning is done without the need for the user to first open the case and decide whether the main packing compartment 17 should be closed to access or inspection or whether the portfolio section should be opened for inspection.
• the disadvantages of the prior art cases are elegantly overcome. In each instance, when the case is opened from the vertical position, inadvertent spillage or visual access of the contents of the main compartment 17 are substantially prevented.
• the orientation of the case is used to trigger the varying functions of the portfolio latch members
• other means are within the scope of the invention.
• a separate latch operable from the outside before the case is opened to either cause the panel to be fastened to the base shell or to be fastened to the lid shell is clearly possible.
• the alternative attaching or hooking function could be triggered by the carrying handle 21.
• a mechanical linkage between the handle 21 and the catches could be provided such that if the handle 21 is in the vertical position as shown in Figure 5, the portfolio is held to the base shell as shown. However, if the handle 21 is in the position shown in Figure 1, the panel is held in the closed position in the lid shell.
