1 Claim.
(01. 280-1135)
The present invention relates to an adjusting
and ?xing device on ski-bindings. This device
enables a ?ne adjustment of the toe-jaws and
an adaptation thereof to the shoe which can be
5 effected positively and with little expense of
time.
The accompanying drawing illustrates, by way
of example, an embodiment of the invention.
Fig. 1 is a plan view of the invention, a part
10 of the covering plate being removed.
Fig. 2 shows a cross-section along the line
A——B of Fig. 1.
-
Referring to the drawing in detail, I repre
sents a base-plate as ordinarily used on skis,
5 two pairs of spring acting adjusting and ?xing
arms 2 being rockably mounted thereon by means
of screws 3 which are screwed into the base-plate,
said arms 2 being bent at their ?xing end. Each
of said arms 2 is provided with a downwardly
20 projecting pin 4. Each toe-jaw 5 has two groups
of grooves or notches extending along an arc
of a circle and being formed with recesses 6
arranged in pairs, into two opposite ones the
pins 4 of the rocked arms 2 may be forced in
25 order to ?x the jaws 5 in their adjusted posi
tion.
The adjusting and ?xing of the jaws 5
by means of the arms 2 and their pins 4 can
be positively effected with great exactness and
with little expense of time. When the arms 2
30 are adjusted the pins 4 of the arms 2 are allowed
to yieldingly engage with the respective recesses
6 whereupon the jaws rest irremovably in the
adjusted position.
The adjusting arms 2 may be rigid and in this
35 case they must be lifted for the length of the
pins 4 when the jaws shall be displaced after
the screws 3 have been loosened. With spring
like adjusting arms a loosening of the screws 3
is not necessary.
For adjusting, the jaw portions are forced to
wards the shoe while the jaws are opened and
the ?xing screws ?rmly tightened. Afterwards 5
the adjusting and ?xing arms are rocked and
the pins forced into the corresponding recesses
6 whereupon the screws of the adjusting and
?xing arms are tightened.
The toe-jaws 5 are positively held in the di- 10
rection across the ski when the adjusting pins 4
are forced into the recesses 6 and the screws 3
are tightened. For displacing of the jaws 5
the adjusting and ?xing arms 2 are rocked into
the longitudinal axis of the ski after the screws 15
3 are loosened. The arms 2 may be laminated.
Both ends of each toe-jaw being adjustable
in the present ski-binding, a very ?ne and pre
cise adjustment‘ of the toe-jaws and complete
security against all displacements are obtained. 20
What I claim is:
An adjusting and ?xing device on ski-bindings,
comprising a front pair and a rear pair of ad
justing and ?xing arms, a pin on each of said
arms, a pair of adjustable toe-jaws of angular 25
section, a group of grooves in each toe-jaw op
posite each of said arms, said grooves extending
along arcs of a circle eccentric to the rocking
axis of the corresponding adjusting arm and
diiferent distances from this axis, recesses formed 30
in opposite pairs on the edges of said grooves
and adapted to receive said pins, a base plate
having a screw between the said adjustable toe
jaws, serving as a rocking axis for the said arms
and as a means to ?rmly hold the said pin be- 35
tween one or another pair of said recesses.
