3 Claims. (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
. 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
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
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
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.
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
2. ‘
apertures (not shown) in the portion I3 into en
gagement with the material of the knob I2.

members may ‘be readily separated by a slight
tipping of the knob I2 to disengage the cooperat
ing fastening means.

adapted to operate entirely independently of the
means for securing the bag material to the frame.

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
I claim:

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

engaged through the‘natural resiliency of said
an angular extension on the upper end of said
reducedneck extending toward the other frame member and cooperative fastener means between
said extension and the other frame member.
