Abstract: A rigid carrying case (20) having a handle and a hinge in the centre, is combined with a removable flat top (22) that is attached when opened forming a portable table. Legs (52) are stored within housings (32) located inside of the case (20) and are released by depressing an actuator (64) protruding outside of the case permimeter. The legs (52) cross each other thereby holding them rigidly in place with assistance of a non-slipping resilient bumper (60) on the end of each leg. The housing (32) is attached inside the case (20) with a housing cap (36) on one end and restraining means on the other consisting of a locknut (44), spacer (46), locknut with a lip (48), and an ''O'' ring (50). A second embodiment adds a separable leg extension (80), and a third embodiment adds length to the legs (52) utilizing a second telescoping leg (82).

Description: DESK CONVERTING CARRYING CASE TECHNICAL FIELD The invention pertains to the general field of hand carried utility cases and more particularly to a brief case incorporating a set of telescoping legs that allow the case to be propped upright in an open position and a table placed across its two top sections. BACKGROUND ART Conventional hand carried cases such as briefcases, rigid camera cases and other utility cases are designed primarily to allow equipment, papers, etc. to be stored and carried. Attempts have been made to add additional utility to these cases by incorporating foldable legs and tops. However, in most cases, the additional implements required to increase the utility and cumber¬ some, reduce the carrying capacity and are not authentically designed. A search of the prior art did not disclose any patents that read directly on the claims of the instant invention, however, the following U.S. patents were considered related: Patent Number Inventor Date Issued 4,412,604 Bell, et al Nov. 1, 1983 4,034,518 Trecker July 12, 1977 2,522,322 Wallace Sept. 12, 1950 1,211,829 Eades Jan. 9, 1917 873,855 Goldin Dec. 17, 1907 Bundesrepbublik Deutschland 815,225 Peter Reimitz, Wetzlar/Lahn Oct. 1, 1951 Bell teaches a combination luggage case and stand with an extension. The case has an openable top with a hinged cover and foldable legs. This folding structure includes a fork shaped support used as a table, and a second position raising the nose to be horizontal, form- ing an extension table. Trecker discloses a portable cot and table that folds into a carrying case. Extensions are added to lengthen the structure, and the legs are added to the center bottom of the structure. The corner legs are hinged and swing into the case when not in use. All six legs are extensible to raise the height of the flat hori¬ zontal surface to enable the unit to be used as a table. Wallace utilizes a biforcated leg structure option¬ ally supporting luggage sections in a horizontal position. The legs are removable and longitudinally adjusted by nesting together with sockets extending into the container without being in communication with the interior thereof. The legs may be used in triplicate in one of the two alternate positions, serving as a flat topped table with the container closed. A fourth leg is added when the container is opened flat. Eades employs four supporting legs to impart the requisite sustenance to a- suitcase to be converted into a table. The legs are hinged from beneath and embody two telescoping connecting sections, the upper being hollow having threaded therethrough a clamping screw coacting with a second section which provides the predetermined relative adjustment. The case is characterized by three pivotally connected units adapted to be folded into superimposed relation. Goldin practices a dressing case, or valise, convert able to form a table to be used in railway compartments, and the like. The case is provided with four collapsible legs formed of lengths of tube made to slide one within the other, the inner one being provided with a slot, or groove, in which a stud, or pin, slides. The lower end of the slot being formed into a helical shape permitting the legs to be twisted reducing the width of the gap while increasing the friction, allowing the leg to stand by it¬ self. The legs are stored within the case when telescoped together with only silver plated disks visible from the exterior, shaped so as to facilitate easy withdrawal and fixing. The German patent issued to Reimitz teaches a brief¬ case, as illustrated in FIGURE 3, with crossed telescoping legs that are held in place by a detent pin (5) when ex¬ tended into a hole in the leg.. The legs are in "U" shape and pivotally attached with separable brackets (6) . In order for the detent pins to line-up with the hole in the "U" shaped leg, a groove is placed in the extended leg and corresponds with an operative (7) on the bracket (6) . DISCLOSURE OF THE INVENTION When.people travel, the convenience of having a surface, such as a table, may not always be available. In particular, when waiting at an airport or train station time may be available for the businessman to utilize the opportunity to great advantage if there were such a sur¬ face available. ' Further, conditions arise where one may be seated, such as in a lobby, or anywhere one is waiting, where tables may be available, but not located conveniently Therefore, the primary object of the invention allows con¬ version of a conventional briefcase, in which papers and documents are normally carried, into a convenient elevated, open upright position on which a table suitable for writ¬ ing, calculating, or the like may be fastened. The table allows the user to have available all of the pertinent information without opening the briefcase again by simply reaching inside. Further, storage is easy with such an arrangement, and since the top is covered, confidential material is not easily viewed by those casually passing by. The table may be of a one price construction or may have a hinge that allows the table to be folded and placed inside the briefcase when not in use. Another object of the invention deals with the un- obtrusiveness of the briefcase modification. The only evidence available from the outside are snap fasteners located on the top, release buttons oh the sides, and leg end bumpers on the bottom that appear to be the usual resilient briefcase hardware. The fasteners on the top are relatively small and do not extend greatly from the surface, while the leg release mechanism on the side is characterized by a round flange with a radial button therein, both components plated or finished in like manner to that of the existing case hardware. To the unknowing, the briefcase would not appear unusual during its normal carrying utility. Still another object of the invention provides a lightweight addition to the case. This modification requires only a writing table top and four legs to pro¬ vide the additional utility. In all cases these com¬ ponents are designed using lightweight material, such as aluminum and composition board, well known for their strength to weight ratio. The ease of operation is yet another object of the invention, as the operator is to simply push the leg re¬ lease buttons located on the side of the case and the legs extend by gravity. The case is then opened in the normal manner with the top placed on the open edges and secured with snap fasteners well known in the art. The crossed position of the legs eliminates the need for fur¬ ther securement with the device ready for operation using these simple procedures. As no particular direction is required, the procedure becomes obvious to the user immediately. These and other objects and advantages of the pre¬ sent invention will become apparent from the subsequent detailed description of the preferred embodiment and the appended claims taken in conjunction with the accompany¬ ing drawings.

BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the invention is presented in the terms of a preferred, second, and third embodiment. All three embodiment are primarily designed to provide a portable table with a writing surface in conjunction with a briefcase. The preferred embodiment is pictorially illustrated in FIGURES 1-12, and consists of a rigid carrying case 20, commonly designated as a briefcase. This case 20 includes a carrying handle and a clam shell hinge, opening in the center with locking hardware, and a pair of articulated opening stops. The case 20 may be made of any material, such as aluminum, leather, or vinyl, with a cardboard or composition board secondary structure. No special construction is required as long as the case 20 is rigid and the corners are re¬ latively square. A removable table top 22 is utilized that has a flat surface on the upper side, and is sized to be attached to the opened edges of the case 20. The top 22 is composed of a rigid substance, such -as composition board, aluminum, or the like, and at least two edges of the case are in contact when installed on the briefcase providing a planar working surface. The top 22 is con¬ nected to the opened case with fastening means 24 pro¬ viding a secure attachment in a removable manner. This fastening means 24 preferably consists of a plurality of resilient tabs 26 positioned on the underside of the top 22 at each corner with male snap fasteners 28 secured thereupon. The tabs 26 are, in turn, attached to the top 22 with rivets, adhesive, or the like. A plurality of mating female snap fasteners 30 are fixqd to the case 20 at the appropriate location interlocking together forming a removable joint when so attached. The table 22 may be constructed in one piece or may have a hinge 90, as shown in FIGURE 5, that allows the table to be folded and place inside the briefcase when not in use. A plurality of leg retaining housings 32 are in¬ stalled within the case 20 at each outside corner, pro¬ viding a storage enclosure and structured guide for the legs. The housings 32 are hollow and cylindrical in shape, in pipe fashion, with external threads 34 on each end. A housing retaining cap 36 is threadably positioned on the upper end of each housing 32 and contains and aligned bore 38 and a spring retaining cavity 40 on opposed sides. This cap may further contain sharp projections 42 distended from the outermost surface, which is contiguous with the inside surface of the case 20 providing restraining means and interface therewith by penetrating the case lining. In another embodiment, not shown, the housing retaining cap 36 may be deleted. In this design a resilient" cap or a hard cap with sharp projections is inserted over the top of the housing 32 which then makes contact with the inside surface of the case 20. Each housing 30 contains a telescoping leg 52 that is slideably positioned within. This leg 52 is in tubular shape and is slightly smaller in diameter than the inside of the housing 32 allowing a free slip fit therebetween. The leg 52, as' well as the housing 32, is made of a structurally sound material, such as metal, or thermoplastic, with aluminum of a hard, heat-treated temper being preferred. Leg retaining means are disposed integrally with each leg 52 limiting the extension of travel when the leg 52 is advanced from the housing 32. This is accomp¬ lished by the use of a male tapered end plug 54 and a plug "O" ring 56 on the end of each leg 52. This configuration prevents removal of the leg 52 from the housing 32 by creating a mechanical interference when the leg 52 is extended almost entirely from the housing 32 by contact with the lip of the locknut 48 in a rigid manner. On the opposite end of the housing 32 restraining means are included in the form of an internally threaded locknut 44 and spacer 46 positioned within the case 20 on one side, and an internally threaded locknut with a lip 48 and a resilient "0" ring on the other outside of the case. This restraining means connects the leg retaining housing 32 to the case 20 on the end opposite the retaining cap 36 and joins the housing 32 permanently thereunto by urging the cap 36 onto the inside surface of the case 20 in a compressible manner. This restraint is initially adjusted by relying upon the external threads 34 of the housing 32 for movable positioning. The leg 52 may retain itself by the crows- osition it assumes when the case 20 is opened or an alternate method incorporates the use of a round retaining button 53 with a flat head attached to the leg 52 and a compression spring 55 between the button 53 and the plug 54, best illustrated in FIGURES 6 and 8. A slot 57 is located in the locknut 48 that receives the button 53 allowing it to pass freely therethrough when in alignment. In operation the leg 52 is extended and the user pulls the leg outwardly against the spring tension and rotates the leg until the button 53 is out of alignment holding it compressably in place. Retraction is accomplished in an opposite manner. Resilient end means are fixed to the extended ends of the legs 52 to provide an elastic surface on which the case may rest. This end is comprised of a threaded sleeve 58 fixably positioned within the open end of the leg 52 with a resilient bumper 60 connected by a fastener, such as a screw 62. The bumper 60 is the same approximate diameter as the leg 52 and is formed of synthetic rubber, or soft thermoplastic material. A leg release actuator 64 is slideably positioned over the cap 36 and mechanically" restricts the movement of the leg 52 when retracted and allows release by exter¬ nal actuation from outside of the case even before open¬ ing. This actuator 64 consists of a rectangular keeper 66 having a narrow end slightly larger on the inside than the outside of the retaining cap 36. The function of the keeper 66 is to transmit the manual actuation from the outside to the inside of the cap. A manual plunger 68 is attached to one of the narrow sides of the keeper 66 and depends outwardly with a release pin 70 similarly attached on the other, except it extends on both sides. The release pin 70 contains a stepped shoulder with a hole therethrough with the small end protruding outward¬ ly, and the large end to the inside. Pin retaining means 72, in the form of a cotter pin, holds the pin 70 into the keeper 66. A compression spring 74 completes the assembly and is disposed between the narrow side of the keeper 66, opposite the pin 70, and nests into the spring retaining cavity 40 of the cap 36. The assembly is pictorially illustrated slideably fixed to the cap 36 in FIGURE 6 and is depicted removed and singly in FIGURE 12. A flanged bushing and lockring 76 are connected through the side wall of the case 20, and are in alignment with the leg release actuator 64. The manual plunger 68 penetrates through the bushing 76 and extends to the outside of the suitcase 20. The plunger 68 is contained and spring loaded to hold the pin 70 against the plug "0" ring 56, keeping the leg 52 in the retracted position. In operation the case 20 is held in the vertical position and each plunger 68 is depressed one at a time. This slowly distends the legs 52 to their maximum exten¬ sion where they are held in place by the lip of the lock- nut 48, engaging the "0" ring 50. The case 20 is then opened in a normal manner and placed on the floor. The position of the crossed legs 52 held by the bumper 60 on the end steadies the case 20 and provides sufficient strength to be held in the upright position. The table top 22 is then removed from the case interior and snapped onto the upper surfaces of the case 20. Stowage is ob¬ tained by the reverse procedure. A pair of writing implement holders 78, serving to hold pens and pencils, as well as covering the housings 32, are attached on the inside of the case. The holders 78 contain an open ended pocket, and the body is a re¬ silient member stretching between the sides and ends to form a taut cover. The second embodiment, illustrated in FIGURES 15 and 16, is comprised of the same elements as previously described, except a removable leg extension 80 is posi¬ tioned over each telescoping leg 52. These extensions 80 have one end slightly larger in the inside diameter than the outside diameter of the leg 52, and the other end the same size as the basic leg. This allows a slip fit there¬ between and elevates the invention to a convenient height to write upon when seated. The extensions 80 are stored inside the case 20 when not in use. The third embodiment is illustrated in FIGURES 13 and 17, again including all of the elements thus described. The only difference is the addition of another telescoping leg and indexing to allow the release actuator to hold the leg in place. The second telescoping leg 82 is identical with the first, except the addition of an indexing pro- jection 84 near the extended end. The locknut 44 is also slightly different in that it contains a recess 86 in the bottom surface. Finally, the male tapered end plug 54 is replaced by a female plug 88, shown in FIGURE 13, that allows both telescoping legs 52 and 82 to nest com¬ pletely within. In operation the legs are distended, as before, and the set-up is identical. To retract the legs, the second leg 82 telescopes into the first leg 52, and. when the first leg 52 fully enters the housing 32, the projection on the second leg 84 nests into the recess 86 in the locknut 48. This alignment allows the release pin 70 to enter through a hole 90 in the first leg 52 to mate with the "0" ring 56 on the female plug 88. The balance of the operation and utility remain the same. While the invention has been described in complete detail and pictorially shown in the accompanying draw- ings, it is not to be limited to such details, since many changes and modifications may be in the invention without departing from the spirit and the scope thereof. Hence, it is described to cover any and all modifications and forms which may come within the language and scope of the appended claims.
