ADJUSTABLE UTILITY BAG William W. Kurzrock, Chicago, Ill. Application July 21, 1958, Serial No. 749,795 1 Claim. oi. 1so-1.7

My invention relates to new and useful improvements in an adjustable utility bag and has for its principal object a structure which provides a primary bag or receptacle and a secondary bag or receptacle attached thereto and adapted to provide separate receptacles.

Another object of my invention is in the provision in a device of this character of a structure which provides a sightly bag of commodious dimensions adapted to be readily converted into a relatively small and compact bag which is attractive and easy to carry.

Yet another object of my invention is the provision in a device of this character of a bag which is economical to manufacture and simple to use.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 1 is a front elevational view of my utility bag in its extended condition;

Fig. 2 is a rear elevational view of my utility bag folded into its smallest condition and showing indotted lines, its previous size; V

Fig. 3 is a rear elevational view of my utility bag similar to Fig. 1;

Fig. 4 is a rear elevational view showing the bag folded into its first small size;

Fig. 5 is a rear elevational view showing my utility bag in its second folded size;

Fig. 6 is a rear elevational view showing my utility bag shown in its next smallest size; and

Fig. 7 is a rear elevational view of a modified fold showing a different size bag over that of Fig. 4.

My invention provides a comprehensive as well as utilitarian and attractive bag receptacle which can be readily adjusted to six ditferent sizes by means of strategically folding and fastening certain ends in predetermined positions.

Referring to Fig. 1, I show a receptacle or bag 10 comprising a front panel 11 and a rear panel 12. These panels may be stitched together along corresponding edges thereof in a manner to provide an open top or mouth portion. It is contemplated by me that my bag maybe made of any flexible and foldable material or may be made of a pliable plastic in which case the certain cor- States Patent i wardly so as to cover the upper portions of flaps 28 and i responding edges would he heat sealed. Under the lat- On the front panel 11, I connectin any suitable manner a panel 14 which is also of, a trapezoidal form. This panel 14 provides a secondary compartment which is adapted to beclosed by a flap 15 carriedby the uppergv free edge of the front panel 11. This flap 15 may be,

closed by a suitable snap fastener. 16 as viewed in Fig.1. Referring to Fig. 3, I illustrate suitable snap fasteners 17 and 18 in the lower corners thereof. whel'ljlhe bag is converted to its next succeeding smaller size, these fasteners 17 and 18 are adapted to connect to fasteners- 19 and 2t) fastened at predetermined 'pointson the rear,

panel 12; When the corners are folded, the-bag will -assume the shape illustrated in Fig. 4. V

The rear panel 12 provides corresponding oppositely disposed fasteners 21, 22, 23 and 24, the latter'two being situated adjacent the connection of the handle 13 with the top open edge of the bag. The former fasteners 21 and 22 are adapted to be located so that they will be exposed after the lowermost corners of the bag have been folded into the position illustrated in Fig. 4. To reduce the bag to its next succeeding smaller size, the fasteners 21 and 22 are brought into fastening engagement with the fasteners 23' and 24, while the bag is folded along line 25 as illustrated in Fig. 5. The bag so folded will again resume its trapezoidal form. 1

As viewed in Figs. 5 and 6, the corners 26 and 27 are folded along lines A and B so that they create flaps 28 and 29. The flap 29 is adapted to be folded into facial abutment with the receptacle While the flap 28 is folded so as to overlie the flap 29 as shown in Fig. 6. The flaps 28 and 29 are held in folded position by the fasteners 30 and 31 which are connected to the front panel 11 but which are brought into facial abutment by the folding hereinbefore described.

A closure flap 32 which is carried by the'free edge of the rear panel 12, may then be folded so as to overlie the panel 28. The flap 32 has a fastener 33 which is adapted to cooperate with a like fastener 38 on the outer face of the flap 28 so as to secure the flaps 28 and 29 in their folded position.

In order to fold my utility bag into its smallest size, the flap 32 is opened and the uppermost'corners 34 and 35 of the bag as illustrated in Fig. 6, are'then folded in- 29 in the position of the dotted lines as shown in Fig. 2.

The bottom portion 36 of the bag as viewed in Fig. 6 is then folded so as to cover the corners 34 and 35 as shown in Fig. 2. In such a position, the flap 32 is brought over the bottom edge 36 and connected to a fastener 37 which is provided by the front panel 11. In such affolded condition, the bag may be readily stored or carried in a pocketbook or pocket of a garment.

Referring to Fig. 7, I illustrate a modified fold whereby the lowermost corners of the bag are folded so that they are brought into facial relation with the uppermost corners of the trapezoidal formed bag. There the. fasteners 17 and 18 are adapted to connect to the fasteners, 23 and 24.

As fully described, my utility bag with its trapezoid shape can be readily adjusted by means of the described folding-operations to six diflerent highly attractive sizes. In this principal design, I am using 60. base angles and a 60 folding principle in order to accomplish the many sizes as he'reinbefore explained.

While I have illustrated and described the preferred form of construction for carrying myv invention into ef feet, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, donot wish to be limited to the precise details of con,-

struction 'set 'forth, but desireto avail myself of such variations and modifications as come within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to .protect by Letters Patent'is:

An adjustable utility bag made of flexible foldable material providing a trapezoidal shaped bag-like structure having a front wall and aback wall defining a compartment, handles connected 'to said front and back walls intermediate the ends thereof and projecting outwardly from said bag-like structure at the open end thereof, a

similar shaped wall member secured to said front wall adjacent the open top-of saidJbag-like structure providing a secondary compartment, said bag-like structure having its lower angled corners "foldable inwardly upon the back wall of said bag-like structure onto a line mid-way between the top and bottom thereof where said bag-like structureaisfurther folda'ble between its top and bottom so as to vary the size of the compartment defined by said front and back walls, each of the new lastly formed angled corners foldable in the same manner upon the front wall until the size of said newly formed bag-like structure substantially conforms to the size of the secondary compartment, fastening means on said walls for releasably securing each set of newly formed corners in folded position, and cooperating fastening means for releasably securing other positions of said bag-like structure in folded relation with respect to the open end of said compartment.
