(Cl. 150-29) My invention relates to bag frame structures in combination with fastening means for the same and has for its object to provide a fastening means of simple construction carried by the bag 5 frames in such a way that it will not interfere with the means for attaching the hand bag fab ric to the frames. In the drawing, which illustrates a preferred embodiment of my invention: Fig. 1 is an elevational view of a bag frame 10 . structure and fasteningmeans for the same; Fig. 2 is an enlarged top plan View of the fas tening means shown in Fig. 1 with the frames in open position; ‘ which will be hereinafter more fully described. ' Fig. 3 is an enlarged rear view of my improved 15 main fastener member attached to one of the frame members; Fig. 4 is a bottom view of the fastener installa tion shown in Fig. 3; Fig. 5 is a fragmentary front view of the in 20 stallation shown in Fig. 3; ’ Fig. 6 is an enlarged section taken on the line 6—6 of Fig. 1; and , ' Fig. 7 is an enlarged section taken on the line 25 1-1 of Fig. 1. ‘ ' Referring to the drawing, I have shown in Fig. 1 a pair of frame members I and 2 secured to gether at their free ends by rivets 3 or any other suitable fastening means which will permit the members to‘ be hinged together for relative swing ing movement of one to the other. Although I prefer to use my separable fastener means with frame members of the type described, it should be understood that the fastening means may be used advantageously with frame mem bers of other cross-sections. Before the main fastening member 8 is se cured,,a portion of the ?ange ‘I of the frame mem ber I is cut away, as most clearly shown in Figs. 3 and 5, so as to leave an opening in the ?ange substantially in the center of the frame member. Next the material of the ?ange 1 adjacent to op posite ends of the opening is slotted as at I0 (Figs. 3 and 5) thereby forming lugs II for a purpose The frame members I and 2 with which my improved sep arable fastener means is used are .of the U-shaped cross-section type, as best illustrated in Figs. 6 35 and 7, having an outer wall 4, an inner wall 5, V and a base} portion 6 connecting the two walls. The walls 4 and 5 are spaced apart to form an outwardly opening channel (Figs. 6 and 7). The inner wall 5 has a ?ange ‘I integral therewith 40 and extending in substantially right angular re lationship to the inner Wall. In my preferred form, as illustrated in Figs. 6 and 7, the outer wall 4 is bent away from the inner wall 5 so that the ‘bag material (not shown) may be brought over the outer wall 4 of each frame mem ber and clenched in the channel between the inner and outer walls by a subsequent bending of the outer wall toward the inner wall. The frame members I and 2 are held in locked 50 position by a separable fastening means, as most clearly shown in Figs. 2 and 6, comprising a main fastener member 8 secured to the frame mem ber I and any suitable interengaging means car ried by the frame member 2, such as the projec 55 tion 9, pressed from the material of the ?ange ‘I. The main fastening member 8, as best illus trated in Figs. 3-7, comprises, in my preferred form, a knob means I2 of any suitable shape or material superposed upon a one-piece plate mem ber. The plate member has a ?ange portion I3 at one end and an L-shaped attaching portion =20 at the other end having a foot portion I4 and an upwardly extending portion I5.‘ When the plate member is ?nally assembled with the frame member I the L-shaped portion is secured in the U-shaped ‘cross-section in such a way that the 25 foot portion I4 is positioned at the bottom of the‘ U-shaped cross-section (Fig. 6) in substantially adjacent relation to the base portion 6, and the upwardly-extending portion I5 lies substan tially adjacent to the inner wall 5 (Figs. 6 and 7) having portions at opposite ends disposed between the ?ange ‘I and the frame base portion 6 (Fig. 5). The foot portion I4 is useful as an aid to maintaining the plate member in ?xed position within the cross-section, but I do not wish to be‘ limited to the same because satisfactory attach ment to the frame member has been provided with this portion omitted. The portion I5 has a re duced neck portion I5?L extending through the opening in the ?ange ‘I and joining the ?ange 40 portion I3 to the main body of the portion I5 (Fig. 5). The plate member is held in secure attachment to the frame member by means of the lugs I I which are bent to clamp the upwardly extending portion I5 of the plate member ?rmly 45, against the inner wall 5, as most clearly shown in Figs. 5 and 7. After the plate member has been secured in ?nal position the ?ange portion I3 overlies the outer edge of the wall 5 between the ‘ lugs II and extends from the portion I5a toward the frame member 2. The knob I2 is attached to the portion I3 in any suitable way such as by a nail or screw means I6 (Fig. 4) headed on the lower side of the portion I3 and extending through 50 2. ‘ 2,128,736 . apertures (not shown) in the portion I3 into en gagement with the material of the knob I2. tening member having a plate portion clamped to said inner wall by means of said attaching lug, said plate portion extending upwardly through the opening of said ?ange, and a ?ange portion part of the ?ange I3 and adapted for cooperative ' ‘ integral with said plate portion and disposed 5 fastening engagement with the projection 9. The above said inner wall, the said flange portion A fastener socket means I 1 (Figs. 2, 4 and 6) is provided, in my preferred form, as an integral socked means I‘! is preferably formed by indent ing the portion I 3 to form a recess of bow-shaped cross—section, as best illustrated in Fig. 6. How 10 ever, I do not wish to be held by the speci?c form having an integral separable fastening means, and cooperating fastening means carried by said other frame member. . 2. A bag frame structure including a pair of 10 of'separable fastening means illustrated and do, ' frame members hinged together at their free scribed because it is apparent that there may be ends, each of said frame members having an an interchanging of the means ‘relative to the v20 without departing from the spirit of the inven tion. of one of said frame members having an opening 1 15 In the normal operation of the fastening means v in one portionithereof, attaching lugs integral which I have just described, when the frame with the outer edge of said last mentioned inner members I and 2 are moved into closed position, ' wall, anda fastening means including a projec the, free edge I8 of the ?ange portion l3 will en gage the projection 9 and as pressure is applied to opposite sides of the frame construction, mostly .therrnatural resiliency of the frame'members will permit the edge I8 to ride over the projection 9 until the projection snaps into locking engage ment with the recess socket means II. The frame members may ‘be readily separated by a slight tipping of the knob I2 to disengage the cooperat ing fastening means. 7 It is ‘apparent that by my invention I have provided a separable fastening means which is adapted to operate entirely independently of the means for securing the bag material to the frame. .35 outer wall and an inner wall forming an out wardly opening channel, said inner walls each having a ?ange extending outwardly from the upper edge thereof, the ?ange of the inner wall parts with which they are associated or slight 15 modi?cations made in the form of the means Further-more, my fastening means is of relatively imple and inexpensive construction capable of easy assembly with the respective frame members with-which it is adapted to be used. AlthoughI have illustrated and described a pre ferred embodiment of my invention, I do not wish torbe limited thereby because the scope of my invention is best set forth in the following claims. ’ I claim: 1. A bag frame structure including a pair of 55 frame members hinged together at their free ends, each of said frame members having an outer wall and an inner wall forming an out wardly opening channel whereby a bag material may be secured in said channel between said outer and inner walls, said inner walls each hav frame members, and a fastener operating means carried by said ?ange portion. ‘ 3.
