Products Company, Chicago, Ill., a corporation

5 Claims.
This invention relates to a slide buckle and has
special reference to a device adapted to be mount
ed on belts, straps, and the like, for the support of
garments or other objects on the person, or for
otherwise detachably securing articles together.
More particularly, this invention relates to a
slide buckle comprising a pair of slidably engaged
frames in which one frame thereof has side bars
and cross bars connecting the side bars with one
lo of the cross bars presenting a strap-engaging face
inclined relative to the plane of the frame, the
other of the frames comprising portions con
nected in face-to-face spaced relation with op
posed edges thereof overlying the side bars of the
15 ñ-rst mentioned frame rto be guided in a longi
tudinal movement thereby.
One end of the con
nected portions has a strap-receiving slot, the
other end thereof being inclined in the direction
of the inclined cross bar of the other frame for
20 co-operating therewith to clamp a strap threaded
therebetween and through the strap-receiving
slot in various adjusted positions as desired.
The device of the present invention is adapta
ble for use with various types of objects, particu
25 larly on the person, and may be employed with
slight variations not departing from the spirit of
the invention, universally where detachable con
nections are desired to be made. However, in the
drawing and in the following description, the slide
30 buckle will be described and shown in its associa»
tion with a strap of a shoe and with a belt, one
of the frames being fiXedly attached to one end of
the belt or to one end of the strap of the shoe,
the other free end of the belt or shoe strap being
threaded between co-operating slidably engaged
frames for clamping the belt or strap relatively
thereto. It will, of course, be readily apparent
that various other uses may be made and that
this invention is not to be limited to the specific
40 uses herein described and illustrated.
One of the objects of this invention is to pro
vide a buckle comprising a pair of slidably en
gaged frames of the type hereinabove described
in which the strap threaded therethrough may
45 be conveniently and easily adjusted in either di
rection.
A further object of this invention is to provide
a slide buckle comprising a pair of slidably en
gaged frames of the character named above in
50 which the` construction may be relatively inex
' pensive to manufacture, may be durable and sim~
ple in construction, and simple in threading and
manipulation.
`Other objects and advantages will hereinafter
55 bev more particularly pointed out and for a more
(Cl. 24-194)
complete understanding of the characteristic
features of this invention, reference may now be
had to the following description when taken to
gether with the accompanying drawing, in which
latter:
`
Fig. 1 is a front elevational View of one form of 5
buckle embodying the features of this invention,
the buckle being attached to a strap of a shoe;
Fig, 2 is a front elevational View of a buckle
embodying the features of this invention, the
buckle being attached to a belt and the belt being
fragmentarily shown;
Fig. 3 is a view similar to Fig. 1 showing the
free end of the strap removed from the buckle;
Fig. ¿i is a lateral sectional View taken on the 15 `
line 4_4 of Fig. 3 with the belt removed;
Fig. 5 is an enlarged longitudinal sectional view
taken on the line 5_5 of Fig. 2 prior to a clamp
ing engagement of the slidably engaged frames
with the strap;
20
Fig. 6 is a view similar to Fig. 5 showing the
belt in a clamped condition between the slidably
engaged frames of the buckle;
Fig. '7 is a perspective view of one of the frame
members of the slidable buckle of this invention; 25
and
Fig. 8 is a perspective View of the other frame
member of the buckle of this invention.
Referring now to the drawing and more par
ticularly to Figs. 2 to 8 thereof, the construction 30
therein shown comprises a pair of frame members
iii and il, the frame member l0 being pref
erably substantially rectangular and having side
bars l2 and I3 connected together by cross bars
lli and l5. The frame member Il comprises por- 35
tions connected in a face-to-face spaced relation
and is preferably formed of a strip folded trans
versely on a line intermediate the ends thereof
to provide portions IS and l1. The opposed edges
I8 and i9 of the folded strip overlie the side bars 40
i2 and i3 of the frame lß or preferably the ears
2l] and 2l, respectively thereof, projecting in
wardly therefrom in a direction toward each
other.
The cross bar l5 of the frame ID is preferably 45
formed to present a relatively wide strap-engag
ing face which is inclined relative to the general
plane of the frame. The frame Il is provided
with a strap-receiving slot 22 adjacent a pref
erably enlarged end of the connected portion I6 50
of the folded strip and the other projecting end
23 of the connected portion I1 thereof being in
clined with respect to the main portion of the
frame and in substantially the same direction as
the inclined cross bar l5 of the other frame.

strip, a pair of longitudinally extending projec
tions 24 and 25 are preferably slit and deformed
from the material forming one face I6 of the

trally of the shoe, the frame of the buckle should
be of a symmetrical design. For example, if the
buckle were to be positioned on the side of a
shoe, then a frame, such as that illustrated in
connection with Figs. 2 to 8, may be employed.
However, were the buckle to be used on the center

as the wing 15b, the wing 15b corresponding to

The cross bar lli of the frame l@ is preferably the inclined cross bar l5 of the frame of Fig. 6.
Referring to Fig. l of the drawing, one end 26a

latter bar corresponds to the cross bar I4 shown
20 of the buckle permanently to one end of a belt

or strap.
Referring more particularly to Figs. 5 and 6, extending from and being part of the frame of
one end 2t of a belt 2l is looped about the cross
bar l@ and is permanently secured thereto by a
25 fastener 23. The fastener is said to be a perma
nent connection in a relative sense only since it is
to be understood that the buckle may be removed
from the strap if it is so desired by detaching
the clasp. The belt 2l is positioned about the
30 object or person, the free end of the belt passing
through a slot 22 and thence between the co
operating cross bars l5 and 23 of the frames iii
and ll, respectively.
The end of the strap 2l

exposed and being symmetrical. The structural
characteristics of'Fig. 1, therefore, are exactly
the same as that described in Figs. 2 to 8, in
buckle frame are symmetrical.
While two embodiments of this invention are
herein shown and described, it is to be under
stood that various modifications thereof may be 35
apparent to those skilled in the art without de
In the position of the buckle frames shown in
Fig. 5, the strap is free to be adjusted in either
direction, the slot 22 in the frame il resting

the incline-d cross bars.
However, when it is de
sired to clamp the strap in an adjusted position,
a tension on the free end of the strap 2l provides
a relative longitudinal movement of the frame
45 members in opposite directions, the frame lll
being held against movement while the frame
il .moves in a direction such that the inclined
cross bar 23 co~operates with the inclined cross
bar i5 to clamp the strap between the co-oper
ating faces thereof. The framev li moves longi~
tudinally in its guide in a converging direction
with the inclined cross bar l5 so that the greater
the relative movement between the inclined
members i5 and 23, the lesser the space between
55 the cross members, and when the space there
between is the same or less than the normal width
of the strap, the strap will become clamped.
Aside from the usual clamping action between
the inclined cross bars l5 and 23, another force
60 is presented since it will be noted that the sup
porting means 2@ for maintaining the spaced re
lation between the folded portions of the strip
does not extend to support the inclined exten-ding
portion 23 thereof. Therefore, when the strap
65 is pulled taut, there will be the added resiliency of
the metal bearing against the strap because of the
unsupported condition of the projecting inclined
30
clusive, with the exception that both sides of the
the end 25 of the strap.
40 so that no clamping action is obtained between

which Illa is a cross bar. A slot |50 is provided
between the cross bar 14a and the Wing [5a to
permit the free end of a strap 21a to be threaded 25
therethrough in order that the appearance value
tion and, therefore, the same is only to be limited
by the scope of the prior art and the appended
claims.
