Description
BACKGROUND OF THE INVENTION
In the sport of skiing releasable bindings are employed securely to
hold the skis attached to the skiers' boots during normal skiing
activity while automatically releasing the skis from the boots in
response to abnormal strains which otherwise might result in injury
to the skier. While these bindings satisfactorily achieve their
purpose of protecting the skier from injury the skis often run away
from the skier when the bindings are released automatically or are
intentionally disengaged.
Various expedients have been resorted to in the prior art in an
effort to overcome the problem of runaway skis. For the most part
these arrangements are complicated and cumbersome and are extremely
inconvenient to operate particularly for a person wearing ski
mittens.
I have invented a ski safety strap latch which overcomes the
defects of arrangements of the prior art intended to overcome the
problem of runaway skis. My latch effectively prevents skis from
running away when the safety ski bindings are automatically or
intentionally released. My latch is easy to operate even for a
person wearing ski mittens. It lies flat against the wearer's boot.
It is simple in construction and easy to manufacture. It is
reliable.
SUMMARY OF THE INVENTION
One object of my invention is to provide a ski safety strap latch
which is simple to operate even for a person wearing ski
mittens.
Another object of my invention is to provide a ski safety strap
latch which is simple in construction and which is inexpensive to
manufacture.
Still another object of my invention is to provide a ski safety
strap latch which lies flat against the wearer's boot.
A further object of my invention is to provide a ski safety latch
which is rugged and reliable.
Other and further object of my invention will appear in the
following description:
In general my invention contemplates the provision of a latch for
use with a ski safety strap having a loop connected to the ski and
having an auxiliary resilient length fastened between portions of
the strap extending from the loop and adapted to wrap around the
rear of ski boot when the ends of the strap are joined. One end of
the strap carries the latch base which is formed with a hook and
which slidably carries a cover for movement between a position at
which it covers the hook to retain a loop or ring on the other end
of the strap within the hook and another position at which the took
is open to permit the ring to fall away from the hook. A spring
housed by the base and the cover biases the cover to its
hook-closing position.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings my ski safety strap latch indicated
generally by the reference character 10 is used on a ski safety
strap 12 adapted to prevent a ski 14 from running away from a ski
boot 16 upon release of the bindings (not shown) which normally
secure the boot to the ski 14.
The major portion of the strap 12 may be formed of any suitable
material of relatively high tensile strength such for example as
nylon webbing or the like. Rivet 18 or the like passing through the
strap 12 forms the loop 20 which may be attached to the ski 14 by
any suitable fastening device such for example as a snap hook 22
mounted on the ski 14. A pair of rivets 24 and 26 or other
appropriate fasteners secure a length of resilient material 28
between the lengths of the webbing 12 outside the loop 20. In use
of the safety strap 12 as will be more fully apparent from the
description hereinafter the ends of the webbing 12 are joined by
the latch 10 to draw the resilient length 28 around the back of the
boot 16.
My latch 10 includes a base 30 having respective sides 32 and 34
and an end wall 36 at the front of the base. I provide each of the
sides 32 and 34 with a recess 38 provided with an inclined surface
40 for a reason which will be explained hereinafter. Recesses 38
together with end wall 36 form a hook. The other principal element
of my latch 10 is a cover 42 having sides 44 and 46 disposed
outside of the sides 32 and 34 of the base 30 and having an end
wall 48.
The sides 30 and 32 of the base 30 carry a first pin 50 which
extends outwardly through respective slots 52 and 54 in the sides
44 and 46 of the top 42. Top 42 carries a pin 56 which extends
through slots 58 and 60 in the sides 32 and 34 of the base 30. In
this manner cover 42 is mounted on the base 30 for sliding movement
between a position at which the cover overlies the recesses 38 to
close the hook formed thereby and a position at which the recesses
are uncovered to open the hook. Each of the base 30 and cover 42
may be simply fabricated from sheet metal.
A spring 62 housed by the cover 42 and base 30 bears between the
pins 50 and 56 normally to urge the cover to a limit position,
determined by pins 50 and 56 at the ends of slots 52 and 60, at
which the cover closes the hook formed by the recesses 38. While I
may use any suitable spring preferably the spring 62 is formed by a
length of a coil spring which is distorted to a U-shape with the
ends of the legs of the U bearing on pin 56 and with the base of
the U bearing on pin 50.
I secure the base 30 to one end 64 of the strap 12 by any suitable
means known to the art such for example as by rivets 66 and 68. A
post 70 carried by the cover 42 receives a strap 72 which may
easily be grasped by the user to permit him to pull the cover 42
against the action of spring 62 to a position at which the cover
opens the recesses 38.
The other end 74 of the strap 12 receives a ring indicated
generally by the reference character 76 having respective end
transverse legs 78 and 80 and an intermediate leg 82. In attaching
the end 74 to the ring 76 I loop it around the intermediate leg 82
and carry the free end back onto the strap 12 at a point beyond leg
80. I next pass a rivet 84 through the overlapped portions of the
strap between the two legs 80 and 82 and then pass another rivet 86
through free end 74 and a portion of the strap 12 outside the ring
76. Owing to this arrangement the ring cannot freely pivot on the
strap 12 and the operation of assembling the ring in the hook of
the latch 10 is facilitated. It is to be noted further than I
provide the ring 76 with a slight bend intermediate its ends to
make it conform to the shape of the ankle portion of the boot.
In use a safety strap 12 provided with my latch 10 the loop 20 of
the strap is attached to the ski 14 by any means such as by the
snap hook 22. The ends 64 and 74 of the strap 12 are brought around
to a position adjacent the front or side of the boot 16 and the
resilient length 28 accommodates boots of different sizes. The
cover 42 is moved against the action of spring 62 to a position at
which recesses 38 are open to permit the leg 78 of the ring 76 to
be inserted into the recesses. The cover then is released so that
spring 62 moves it to a position at which it closes recesses 38
securely to retain leg 78 in recesses 38. This is the position of
the parts of my latch illustrated in FIG. 4. It will readily be
appreciated that while the spaced pins 50 and 56 and the associated
pairs of slots 52 and 54, and 58 and 60 permit relative sliding
movement between the base 30 and the cover 42, they prevent any
relative pivotal movement therebetween such as might permit leg 78
to escape from recesses 38 even with the cover 42 in closed
position.
When the skier wishes to release the safety strap he merely pulls
on the tap 72 in the direction indicated thereon to move the
housing or cover 42 from the position shown in FIG. 4 to the
position shown in FIG. 5 to open the hook formed at the end wall
36. When that has been done tension in the length 28 causes leg 78
to ride up the surfaces 40 and fall away from the latch 10 as shown
in FIG. 6.
It will be seen that I have accomplished the objects of my
invention. I have provided a latch for a ski safety strap which
overcomes the defects of arrangements of the prior art for
preventing runaway skis. My latch is easy to operate even for a
person wearing ski mittens. It lies flat against the wearer's boot
with the cover closed. It is simple in construction and is easy to
manufacture. It is rugged in construction and is reliable in
use.
It will be understood that certain features and subcombinations are
of utility and may be employed without reference to other features
and subcombinations. This is contemplated by and is within the
scope of my claims. It is further obvious that various changes may
be made in details within the scope of my claims without departing
from the spirit of my invention. It is, therefore, to be understood
that my invention is not to be limited to the specific details
shown and described.
