Application July 13, 1934, Serial No. 734,921

6 Claims. (o1. 153 'g This invention relates in general to frames for ladies hand bags, purses, pocket books and the like, the invention being particularly directed to the structure of the frame for the mouth or opening of the bag.

A frame of this general character includes two approximately U-shaped sections which are pivotally connected together at the extremities of their arms and have the bag covering, such as 101': leather or composition fabric secured thereto, so

that upon relative pivotal movement of the sections, the bag may be opened and closed. Inasmuch as such frames are subjected to hard usage, particularly to repeated and severe strains in 1; opening and closing of, the bags, it is highly desirable that the frames be very strong, but at the same time it is desirable thatthe frames be light in weight so that they shall not constitute too great a burden to the persons carrying them. It has been customary in the art to make such frames by spot welding or riveting pieces of metal together, or by bending metal and then riveting or spot welding additional pieces at the bends to reenforce the frame sections at the bends or 25, angles thereof. Such structures and methods are expensive both in cost of materials andlabor.

An important object of my invention is to provide a novel and improved bag frame and method of making it whereby the frame shall be formed of one piece of sheet material, so as toobviate the necessity for spot welding or riveting, and shall be strong and durable in use and inexpensive to manufacture.

Another object is to provide a novel and im- 35; proved blank for a bag frame section consisting of a single strip of. sheet material which can be easily and quickly fabricated by simple bending operations into a complete strong durable and inexpensive frame section. I

Other objects, advantages and results of the invention will appear from the following description, when read in connection with the accompanying drawings. v

Referring to said drawings in which corres- 45 ponding and like parts are designated throughout the several views by the same reference characters,

Figure 1 is a plan View of a blank for a bag frame section embodying my invention.

Figure 2 is an edge elevention thereof.

Figure 3 is a plan view showing the frame section in the form in which it appears after the first series of bending operations on the blank. Figure 4 is a side elevation of the structure shown in Figure 3.

Figure 6'is a transverse vertical sectional view on the line'i--5' of Figure 3. a

Figure 7 is an enlargedfragmentary'perspec- 5' tive viewof the .channel formed from the blank prior to'bending of the channel;-

Figure 8 is. a top planview of two of the channels pivotally connected together after having been subjected to the first transverse bending op- 1B eration. l. I

Figure 9 'is a side elevation of the structure shown in Figure 8'. l H

Figure '10 is "a: top plan view of the completed bagf-rame. a

Figure 11 is a side elevation thereofshowing a portion of the bag cover applied tothe frame.

Figures 1-2 and 13 are enlarged fragmentary vertical sectional views'on the lines 'l2|2 of Figure l0 showingthe successive stepsin bending the 20 channelitransver'sely. 1 v I g Figure 14 is a similar viewon the line I 3 l3 ofl lgure'lqand' I v Figure 15 is a fra'gmentaryperspective view showing the manner of attaching the cover to the frame.* Specificallydescribing the illustrated embodiment of the invention, 'the' bag' frame comprises twoidentical sections and B' which are approximately lJ-shaped, each including a main portion C and two endportions D approximately perpendicular to the main portions. The extremities'of the end portions -D are pivotally connected at E'asby suitable hollow rivets so that the two sectiensm'ay' swing toward and from each other. V I Each frame section is for-med of a blank I of bendable sheet material for example sheet metal, which has pivot ears 2a: its extremities to receive' the hollow' rivetsE.' One longitudinal edge 40 of the blank has two V-shaped notches 3 spaced] longitudinally thereofpand two openings 4 are formed in the blank alinement with each notch 3 transversely of the strip, said openings also being spaced from' each other in alinementtransversely of the strip. Preferably the openings are triangular as shown, and the adjacent sides 5 of the openings of each pair are parallel to each other and extend longitudinally of the strip as clearly shown inFigure 1. After the blank has been formed as described, it is bent longitudinally along the inner ends of the notches 3 as indicated at 6 and along the edges of the openings 4 adjacent the notches as at 1, and then along the adjacent sides 5 of the openings as at 8 and 9 respectively. The blank is thus formed into a channeled strip having two channels provided with a common side wall and facing in opposite directions, as clearly shown in Figures 6 and '7. The openings 4 are disposed in opposite relation in the side walls of one of the channels and adjacent the base ll of the channel, while the notches 3 are disposed in the outer side wall of the other channel with their inner portions terminating adjacent the base I! of said channel. The notches 3 and openings 4 are thus disposed in alinement or juxtaposition transversely of the strip.

Two of the strips are then connected together by the hollow rivets E and arranged in side by side relation as shown in Figure 8. The two strips may then be simultaneously bent transversely at the openings 4 and notches 3 as shown in Figure 9 so as to form in effect a one-piece mitered joint. During this bending operation, the portion of the base ll of the channel having the openings 4 is doubled as shown at I3 on Figure 12, along the adjacent sides of the openings 4', so that the other sides of the openings are brought intoclose relation, and the sides of the notches 3 are brought together as shown in Figures 12 and 14 respectively. This bending; operation forms one of the end portions D of the bag frame and the other end portion is formed by bending the strip in the same manner at the other openings 4 and notches 3. Thereafter, the doubled portions l3 ofjthe base. ll of the channelare bent or clinched tightly against the adjacent areas of the base of the channel as indicated'at i4 in Figure 13. This completes the bag frame.

, From the foregoing, it will be observed that the bagframe comprises two identical sections, each ofwhich is formed of a single piece of sheet material, and that the frame can be formed easily and quickly and inexpensively by a small number of simple stamping and bending operations. The junctures of the main portions'C and the end portions D of the frame sections .are reenforced by thedoubled portions l4 of the bases of the channels and effectually resist bending of the end portions relative to the main portions of the frame sections under the most severe strains incident to use of a bag. There is no spot welding or riveting required, nor are there any projections or rough edges to hinder the application of the cover to the frame. A cover may be applied to the bag frame in the usual way, for example by turning under the edge of acovering piece F as indicated at G in Figure 15 and clamping said turned edge in the outer channel of the frame section.

1 While I have shown and described the inventionas embodied in certain specific details of structure it should be understood that this is primarily for illustrating the principles of the invention and that many modifications and changes may be made in the details of structure without departing from the spirit or scope of the invention. Y

Having thus described my invention, what I claim is:

1. A blank for a bag frame section comprising a strip of bendable sheet material having spaced V-shaped notches on one longitudinal edge and a pair of triangular openings in alinement with and spaced from each notch and each other transversely of said strip, each triangular opening of each pair having one side parallel to one side of the other opening of the same pair and extending longitudinally of the strip.

2. The steps in the method of making a bag frame section, consisting in forming a notch in one longitudinal edge of a strip of ductile material, forming two openings in said strip in alinement with and spaced from said notch and each other transversely of the strip, bending the strip along longitudinal lines between said notch and one of said openings and along the adjacent sides of said openings to form two channels having a common wall and facing in opposite directions, and then bending said strip transversely through saidopenings and said notch.

3. The method set forth in claim 2 wherein said notch is made of V-shape, and each of said openings is made triangular with one side thereof parallel to one side of the other and extending longitudinally of the strip.

4. The steps in the method of making a bag frame section, consisting in forming a notch in one longitudinal edge of a strip of ductile material, forming two openings in said strip in alinement with and spaced from said notch and each other transversely of the strip, bending the strip along longitudinal lines between said notch and one of said openings and along the adjacent sides of said openings to form two channels having a common wall and facing in opposite directions, then bending said strip transversely through said openings and said notch, and then bending against the base of the corresponding channel the portion of the material between said openings which has been displaced by said transverse bending of the strip.

5. The method set forth in claim 2 wherein said notch is made of V-shape, and each of said openings is made triangular with one side thereof parallel to one side of the other and extending longitudinally of the strip, and with the additional step of bending against the base of the corresponding channel the portion of the material between said openings which has been displaced by said transverse bending of the strip.

6. A bag frame section of sheet material having a main portion and two end portionsdisposed in angular relation to the main portion and iii-- cluding two channels having a common wall and facing in opposite directions, said common wall and the side walls of one channel having mitering openings extending to the base of the channel at the junctures of said end portions with said main-portion, the portions of the base of said channel at said junctures being doubled and pressed against the adjacent areas of the base. and the side wall of the other channel having miteringnotches in alinement with said mitering openings transversely of said channels.
