Forsberg Attorney, Agent, or FirmSchapp & Hatch 1 Apr. 9, 1974 [5 7 ABSTRACT An article of luggage which can be carried by handles, in the manner of a satchel, or may be carried on the back, in the manner of a knapsack or back-pack. An enclosed receptacle of flexible material has substantially flat front and rear faces and a zipper-type closure extending more than halfway around the receptacle. Handle members of generally inverted U-shape are attached at their ends to the front and rear faces near the bottom of the receptacle. The handle members are made of flexible, flat web material stiffened at their midportion and are slidably held in desired position by sections of flexible flat web material sewn to the respective faces of the receptacle a spaced distance above the points of attachment of the handle members to the receptacle. In use, the article is carried by grasping the stiffened central portions, which pulls the flexible flat web material up through the re taining webs, or the flexible flat webs of the handle members are pulled outwardly and the arms of the user are inserted between the pulled out portion and the corresponding face of the receptacle. Adjustment buckles are provided for selectively lengthening and shortening the handle members to accommodate different size arms.
8 Claims, 2 Drawing Figures 1 CONVERTIBLE SATCI-IEL AND KNAPSACK BACKGROUND OF THE INVENTION This invention relates to a CONVERTIBLE SATCHEL AND KNAPSACK adapted to be carried in the hand in a manner of a conventional suitcase or valise, or carried upon the back in the manner of a knapsack.
Previous convertible devices of this type have utilized separate handles, for carrying as a satchel, and shoulder straps, for carrying as a knapsack. Many of these have gone to considerable lengths to conceal the straps when .the bag is being used as a satchel. Generally speaking, the prior devices have either made the straps detachable, so they can be carried inside the bag, or have provided a separate compartment in the bag into which the straps may be retracted, as exemplified in my U.S. Pat. No. 3,622,056, issued Nov. 23, 1971 and entitled Convertible Satchel.
SUMMARY OF THE INVENTION The convertible satchel and knapsack of the present invention is adapted for carrying either as a satchel or as a knapsack without attaching or detaching any portion thereof and without requiring opening or closing of any portion of the bag. To make this possible, the handle members are made of flexible flat web material and are mounted on the bag in such manner that the bag is readily convertible merely by pulling on selected portions of the handle members. Thus, the handle members remain visible in both modes of use and contribute a novel and attractive appearance.
A primary object of the. present invention, therefore, is to provide an article of luggage suitable for carrying in the hand or on the back of the user and in which the carrying straps are part of the handle members and the entire handle members are displayed as part of the appearance of the article.
Another object of the invention is to provide a convertible article of luggage of the character described which is formed and proportioned for easy and convenient carrying in the hand of the user and also for easy and convenient carrying on the back of th user as a knapsack.
Further objects and advantages of the invention will be apparent as the specification progresses and the new and useful features of the convertible satchel will'be more fully defined in the claims attached hereto.
BRIEF DESCRIPTION OF THE DRAWINGS The preferred forms of the invention are illustrated in the accompanying drawing forming a part of this specification, in which:
FIG. 1 is a side perspective view of a convertible article luggage constructed in accordance with the present invention, with the parts of the article being shown in operative position for carrying by hand; and
FIG. 2 is a side elevational view of a modified form of the convertible article of luggage of FIG. 1.
While only the preferred forms of the invention are shown, it should be understood that various changes or modifications may be made within the scope of the claims attached hereto without departing from the spirit of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawing in greater detail, the convertible article of luggage of the present invention basically includes an enclosed receptacle 1 1 of flexible material, such as heavy fabric, having substantially flat front and rear faces 12 and 13, an elongated reclosable separation 14 formed in the receptacle 11 between and generally parallel to the faces 12 and 13 for providing access to the interior of the receptacle, a pair of handle members 16 and 17 of substantially inverted U-shape andhaving leg portions 18 and 19 formed of flexible fiat web material, attaching means 21 and 22 securing the ends of the leg portions 18 and 19 to the faces 12 and 13, and staple means 23 mounted on the faces 12 and 13 in spaced relation to the attaching means 21 and 22 andformedfor slidably receiving and retaining the leg portions 18 and 19, whereby the receptacle 11 may be selectively carried as a satchel by the handle members 16 and 17, or as a backpack or knapsack by inserting the arms of the user between one of the faces 12 and 13, and the associated leg portions 18 and 19, between the staple means 23 and the attaching means 21 and 22.
Preferably, and as here shown, the handle members 16 and 17 at formed of continuous strips of flexible, flat web material, such as the ebbing conventionally used on backpacks and knapsacks. For ease in carrying the article in the hand, the handle members 16 and 17 are stiffened between the leg portions 18 and 19. Preferably, this stiffening is accomplished by folding the webbing longitudinally and securing it in the folded condition, as by sewing. Further stiffening of the handle members is also provided by a member 24 of relatively stiffer material attached to the folded portion of the handle members.
The reclosable separation preferably extends more than half way around the receptacle 11 in order to permit the receptacle to open up wide for easy and convenient access to the interior. As here shown, the reclosable separation 14 comprises an interlocking tooth slide fastener of the type commonly known as a zipper."
As may best be seen in FIG. 1, the receptacle 11 includes front and rear walls, providing the faces 12 and 13, secured to and upstanding from a generally flat bottom 26. A web 27 of relatively flexible material connects the edges of the front and rear walls and cooperates therewith, and with bottom 26, to define the enclosed receptacle 11. i
As shown in FIG. 1, the attaching means 21 and 22 consist of rivets securing the lower ends of the leg portions 18 and 19 to'the wall 12 in laterally spaced relation and adjacent to the bottom 26. Handle members 17, on the opposite side of the bag, is of similar con struction.
In FIG. 1, the staple means 23 comprises short segments of webbing, similar to the webbing used in handle members 16 and 17, with these segments being riveted to the walls 12 and 13 in vertically spaced relation above the rivets 21 and 22. The leg portions 18 and 19 pass loosely between the staple means 23 and the corresponding wall so the handles may be pulled up to the position shown in solid lines in FIG. 1, for carrying in the hand, or may be pulled outwardly to the position illustrated in dotted lines, so the arms of the user can be inserted between the leg portions 18 and 19 and the corresponding wall 12. Thus, conversion of the article of luggage between the satchel mode of carrying and the knapsack mode of carrying is easily and quickly accomplished merely by pulling upwardly or downwardly on the leg portions 18 and 19.
Two basic types of suspension are commonly employed to support backpacks on the backs of the user. In one type, the shoulder engaging straps are spaced apart and are parallel. This provides a two point suspension of the object being carried. In the other basic form of suspension, the shoulder engaging straps angle inwardly from the lower end and come together, or nearly together at the upper end. This provides essentially a one point suspension overlying the spine of the user just below the neck.
The form of the invention illustrated in FIG. 2 of the drawings utilizes the essentially one point suspension concept. As there shown, the staple means 123 provide guides for the leg portions 118 and 119 which are spaced more closely together than the attaching means 121 and 122. The handle member 116 is preferably stiffened as at 124 and the receptacle 111 can be made somewhat triangular in shape to conform generally to the arrangement of the leg portions 118 and 1 19. In either form of the invention, adjustment buckles 128 and 129 are provided in the leg portions so the latter may be lengthened or shortened to accommodate the arms and shoulders of the particular user.
From the foregoing it will be seen that the convertible article of luggage of the present invention provides a novel and attractive structure which may readily be converted between a satchel mode, for carrying in the hand, and a knapsack mode, for carrying on the back and shoulders, merely by moving a pair of straps upwardly or downwardly through guide means.
