This invention relates to an improvement in

clearly shown in Fig. 3, is an apertured stamped‘;

half of the handlebar proper. The stamped
member 20 is substantially semi-circular in plan

Another and still further important object of
the invention resides in the provision of means
for economically producing an exceedingly light
and slightly ?exible device which is exceptionally
strong and well capable of withstanding abusive
treatment.
An additional object of importance is the provi
sion of means for preventing rotation of grips or
handles positioned on the ends of the assembled
handlebar.
Additional objects of importance and advan
tage will become apparent as the following de
tailed description progresses reference being had
to the accompanying drawing in which a pre
ferred embodiment of the invention is illustrated
and wherein,
Fig. 1 is a top plan view of a handlebar which
embodies the invention.
Fig. 2 is a rear elevational view thereof.
Fig. 3 is a sectional view taken on line 3-3 of
Fig. 1.
Fig. 4 is a front elevational view of the post
member.
'
5 is a top plan view of the post member.
Fig. 6 is a sectional view, slightly enlarged,
taken on line 6—6 of Fig. 1.
As shown in the drawing:
The reference numeral It] indicates in general
a post which in the preferred embodiment of the
invention is formed of sheet metal. The lower
portion 12 of the post is curled into tubular for
mation and the upper portion thereof is curved
55 forwardly and is expanded to form a relatively
50
tially semi-cylindrical formation on each side of
the aperture 22 as is best shown in Fig. 6.
Positioned on the member 20 and rigidly se
cured thereto is a stamped member 24 which cor 25
responds in plan formation to the member 20.
The outwardly projecting ?anges 26 along the
front and rear edges of the stamped member 24
are crimped over the outwardly projecting ?anges
of the member 20 as is best shown in Figs. 2, 3,
and 6. The forward edge of the ?at portion I4 is
secured to the ?ange on the forward edge of the
stamped member 20 by the crimped ?ange 26 as is
best shown in Fig. 3.
The crimped ?anges 26 in addition to rigidly
securing the member 24 to the member 20 also
provide a practically indestructible bumper which
protects the balance of the handle bar from in
Jury.
Additionally, it will be apparent that the ?ange 40
member 26 extending along the ends of the han
dle bar will prevent rotation of a grip or handle
positioned thereon.
It will be apparent from the foregoing that
herein is provided a rugged and well built device
capable of standing exceedingly heavy and abu
sive treatment.
Moreover, because of the overlapping front and
rear edges of the structure the possibility of dent
ing and bending the device from running into ob 50
stacles is practically eliminated.
I am aware that many changes may be made
and numerous details of construction varied
throughout a wide range without departing from
the principles of this invention and I, therefore, 55
2

do not propose limiting the patent granted here
on other than is necessitated by the prior art.
I claim as my invention:
1. A handlebar comprising a pair of comple
mentary stampings, one of said stampings hav
ing the entire forward edge thereof crimped over
the ?ange on the forward edge of the other
stamping, means allowing the ?exing of the end
portions of said handlebar, and a post secured
to said handlebar.
2. A handlebar comprising two complementary
stampings, portions of the edges of one stamp
ing being crimped over portions of the edges of
the other stamping, each of said stampings hav
15 ing portions thereof cut away to allow ?exing
of the end portions of said handle bar, and a
steering post secured to said joined stampings.
3. A handlebar comprising an apertured
stamping, said stamping having an upwardly
curved front and rear portion, the edges of said
stamping being turned outwardly, and a comple
mentary stamping positioned on said ?rst named
stamping and having the edges thereof crimped
over said outwardly turned edges, portions adja
25 cent the front and rear edges of the joined
stampings intermediate the center and each end
being of tubular formation.
4. A handle bar comprising a sheet metal hori
zontal portion and a sheet metal vertical por
tion, said vertical portion comprising a tubular
lower part and a forwardly extending substan
tially flat upper part, means formed of said ?at
upper part for securing the vertical portion to
the horizontal portion, said horizontal portion
comprising a pair of complementary stampings
having portions intermediate the center and each
end cut away, and the metal between the cut
away portion and each edge curled into tubular
formation to provide outwardly and rearwardly
projecting ?exible arms.
-
_
5. A handle bar comprisinga sheet metal mem
ber, a bead formed along the entire front of said
sheetmetal member, portions of the handle bar
intermediate the center and each end being cut
away and the balance thereof being formed to
allow a limited ?exing of the ends of the device, 1O
and means in the center of said sheet metal
member for receiving securing members of a
steering post.
6. In a handle bar, a pair of complementary
stampings joined at the front and rear edges 15
thereof, portions intermediate said front and rear
edges being cut away, and a plurality of secur
ing member receiving openings in the central
portion of said handle bar.
7. A ?exible handle bar comprising a pair of 20
apertured stampings, the metal adjacent the
edges of one of said stampings being crimped
over the edges of the other stamping, portions
of each stamping intermediate the front and rear
edges thereof being cut away, and a steering post 25
secured to the joined stampings.
8. A handle bar comprising a pair of comple
mentary stampings joined along the longitudinal
edges thereof, a portion of said stampings inter
mediate the center and each end being cut away, 30
the metal adjacent the cut away portions being
curled to produce two parallel tubular parts on
each side of the joined stampings, and means for
attaching a steering post to the handle bar.
