Improvements in Supports or Stays for Bicycles in Combination with
a Locking Apparatus.
I, LAURITS PETER BRANDT, of Hollændervej 4, Copenhagen, in the Kingdom of
Denmark, Cashier, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
The object of the present invention is to provide a simple and efficient folding
support or stay for bicycles, adapted to be applied to the machine in such a manner
that besides acting as a support it serves to lock the machine.
I effect this object by means of a special folding stay which when unfolded is
connected and locked to one of the moving parts of the bicycle which is by preference
one of the pedal-arms. I will fully describe my invention in reference to the
accompanying drawing in which Fig. 1 is a side view of a pedal-arm of a bicycle
showing the stay fixed behind the pedal-arm and folded outwardly and in a locked
state. Fig. 2 is a rear elevation of the stay folded outwardly, Fig. 3 is a similar
view of the lower section of the stay and Fig. 3* is a side elevation thereof. Fig. 4
is a horizontal section through the stay fork near the link, and Fig. 5 is an end
elevation of the stay in folded up position.
On the frame tube t connecting the crank bracket to the rear wheel of the bicycle
and on the side of the machine opposite to the driving chain is arranged a lug a
provided with a pivot bolt e around which the stay b c can turn in a vertical plane.
The lug a projects in such manner that the stay, when same is unfolded, will assume
a slanting position as in Fig. 2. The stay is made in two pieces b and c of which
the upper one b is shaped as a fork at b¹ and provided with a pivot bolt & round
which the lower piece c can turn. The lower part or foot of the piece c is shaped in
such a manner, that it is not in the way of the pedal, when the stay is folded out.
The lower extremity of the piece c is provided with suitable claw-formed projections
in order that the stop may have a firm grip upon the ground. That part of the
piece c that projects above the pivot bolt d is provided with a stop pin f, which pin,
when the stay is unfolded as shown in Fig. 2 engages in a slot g formed in one of the
arms of the fork 6. By this arrangement the stay is made rigid in one direction.
In order to prevent the stay when in use from turning round the bolt e it is
temporarily secured to the pedal-arm or equivalent moving part of the bicycle after
the latter has been placed in a suitable position. This connection is effected by
means of a projecting rod h fixed to one side of the fork b', and is provided with a
hinged link, adapted to be placed and fixed around the pedal-arm or equivalent
part by means of a suitable locking mechanism adapted to secure a projection k on
the said link i to the fork b¹.
The lock may be arranged on the fork 6¹ and locking is effected at the projection k
on the extremity of the link i as shown in the drawing. The projection k is provided
with a hole m into which the stem of the lock may enter. The projection / enters
into the slot g on the upper part of the fork and thus, when the lock is closed,
prevents the pin f from slipping out therefrom.

page_text: The lock itself, which is not shown on the drawing, is preferably constructed in
such a manner, that it can be opened and closed without the use of a key, for
instance simply by pressing a spring or some similar arrangement.
When the support or stay is not in use it is folded together and assumes such a
position as not to be in the way and not to be exposed to damage when the bicycle is
moving.
Fig. 5 shows the manner in which the stay is folded up after the lock has been
opened. The curved part of the lower piece c is brought in between the two arms
of the fork b¹ and the claw on the extremity of the foot is bent to such shape and
in such manner that it grips upon and partly around the frame-tube t. Then in
order to keep the claw firmly in this position and prevent the same from rattling
against the frame tube a spring is arranged on the lug a which spring can be
sprung around and hold the claw as shown in Fig. 5.
When the stay is required for use it is unfolded outwardly and then the pedal-
arm or equivalent part is placed in a suitable position and attached to the stay
by means of the above-mentioned locking apparatus. The bicycle will then assume
a somewhat slanting position and being supported on three points it will stand
freely without leaning against anything. At the same time the machine will be
locked, the pedal-arm being prevented from turning round by the locking device
above described.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. A folding support or stay in combination with a locking apparatus for bicycles
consisting of a movable stay pivotted to the bicycle frame, and provided with a
movable link adapted to be fastened round one of the moving parts of the bicycle
for example one of the pedal-arms and locked in that position.
2. A folding support or stay in combination with a locking apparatus for bicycles
of the kind indicated in Claim 1 consisting of a fork-piece arranged to turn vertically
on a hinge attached to one of the frame tubes, the said fork-piece being provided
with a pivot bolt round which the foot piece of the stay may turn and a rod
projecting from said fork carrying a link provided with a lock into which a projection
on the fork may be engaged, substantially as above described.
3. In a folding support or stay in combination with a locking apparatus for
bicycles of the kind above referred to the arrangement of the lock on the fork-
piece b¹ and the projection on the link in such a manner, that the projection k
enters into a slot g in the arm 61 of the fork piece, whereby the piece c is held
up and kept in position when the lock is closed, substantially as herein described
and illustrated in the drawing.
