TRACTION DEVICE
Abstract
A device for improving the traction of fishing shoes has several
channel elements in a zig-zag shape disposed on a member having a
relatively flat surface. The elements grip a surface such as a
rock. The member can be the heel or the sole of the shoes or can be
a separate member that is attachable to them.

Claims
I claim:
1. A device for improving the traction of a shoe comprising a
member adapted to be mounted on the bottom of said shoe and having
a substantially planar surface, a plurality of zig-zag shaped
semi-hard aluminum channel elements attached to said surface
adapted to engage and firmly grip an external object, whereby the
traction between the shoe and the object is greatly increased.
2. A device as claimed in claim 1 wherein said member is attached
to said shoe with rubber cement.
3. A device as claimed in claim 1 wherein said member comprises the
bottom of said shoe.
4. A device as claimed in claim 1 wherein said member comprises
carpeting.
5. A device as claimed in claim 1 further comprising blind rivots
disposed through said elements and said member for securing them
thereto.
6. A device as claimed in claim 1 wherein said channel elements
having a substantially rectangular cross-section.
7. A device as claimed in claim 1 further comprising a second
plurality of channel elements attached to said surface in a
substantially closed configuration encircling said first plurality
of elements.
8. A device as claimed in claim 1 wherein said member comprises a
sole shaped portion and a heel shaped portion each having a
plurality of said members attached thereto.
9. A device as claimed in claim 8 wherein said portions are
integral with respect to each other.
10. A device for inproving the traction of a shoe comprising a
carpeting member adapted to be mounted on the bottom of said shoe
and having a substantially planar surface, and a plurality of
zig-zag shaped channel elements attached to said surface adapted to
engage and firmly grip an external object, Whereby the traction
between the shoe and the object is greatly increased.
11. A device for imprving the traction of a shoe comprising a
member adapted to be mounted on the bottom of said shoe and having
a substantially planar surface, a plurality of zig-zag shaped
channel elements attached to said surface adapted to engage and
firmly grip an external object, and a plurality of blind rivots
disposed through said elements and said member for securing them
thereto whereby the traction between the shoe and the object is
greatly increased.
12. A device for improving the traction of a shoe comprising a
member adapted to be mounted on the bottom of said shoe and having
a substantially planar surface, a first plurality of zig-zag shaped
channel elements attached to said surface adapted to engage and
firmly grip an external object, and a second plurality of channel
elements attached to said surace in a substantially closed
configuration encircling said first plurality of elements whereby
the traction between the shoe and the object is greatly increased.
Description
BACKGROUND OF THE INVENTION
The invention relates to traction improving devices, and more
particularly, to such devices that are used on fishing boots.
A fisherman usually likes to fish where the most fish are to be
found. Typically this is in some remote spot where he must stand on
a reverbed or a rock that is slippery due to moss or water covering
it. This obviously greatly reduces the amount of traction between
his shoes or boots and enhances the probability that he will fall
and injure himself. To overcome this, the prior art featured
various devices to improve traction. Among such devices were woven
felt, link chain, and grid link sandles that attached to the boot.
However, while improving the traction, these devices all have
drawbacks. Frequently they have an insufficient number of gripping
edges so that the traction is still too low, they "rock" when
standing on an irregularly shaped rock, they are sometimes heavy,
and wear out fast.
It is therefore an object of the present invention to reducing the
number of falling accidents due to slippage between a shoe or boot
and a low friction surface.
It is another object to improve the traction of a fishing boot with
respect to a slippery rock.
It is a still further object to provide a traction device that does
not rock when gripping an irregularly shaped surface.
It is still another object to provide a traction device that does
not easily wear out.
It is yet another object to provide a traction device that is
relatively light.
These and other objects will become apparent from the following
description when read in conjunction with the following drawing in
which:
The sole figure is an isometric figure of the invention.
In this figure is shown member or backing 10 having two sections 12
and 14. Although two sections 12 and 14 are shown it will be
appreciated that they could be formed as one section as indicated
by the break away edges 16 and 18 respectively. Backing 10 is
preferably made of indoor-outdoor carpeting, such as sold under the
trademark "Ozite." This material is very strong and is lighter than
materials such as rubber. Sections 12 and 14 have substantially
planar outer surfaces 20 and 22 respectively, as well as similar
inner surfaces (not shown) for attachment to a shoe (not shown).
Because of its small size, the heel section 14 has several tabs 15
so as to permit a more secure attachment to the shoe. Secured to
the backing 10 are a plurality of substantially retangular in
cross-section zig-zag shaped channel elements 24. As all of these
are identical only one will be described. The elements 24 are
preferably made from semi-hard aluminum channel stock. This degree
of hardness is preferred becuase it does not wear too fast, yet can
be bent without cracking or breaking. The stock is alternately slit
along its sides at 26, and then holes (not shown) are drilled and
it is bent into the zig-zag shape as shown in the drawing. The use
of channel stock enables the device to have more gripping edges 28
than would otherwise be possible, and the zig-zag shape has the
advantage that the gripping edges 28 can better hold onto an
irregularly shaped object, such as a rock. The channel elements 24
are secured to the member 10 preferably using blind rivots 30. This
type of rivot requires access to only one side of the member 10.
Heel 14 also has channel members 32 which enclosed the zig-zag
shaped member 24.
The entire member 10 is then cemented to the shoe or boot with a
rubber cement, such as Goodyear "Plyobond" to ensure a firm
waterproof mount. This results in a shoe or boot than can supply a
large amount of traction becuase of the zig-zag shape and will cut
into and grip matter such as moss and slime. The device is light in
weight because of the use of carpeting and aluminum and will not
easily wear out.
It will be appreciated that although the invention has been
described with respect to one embodiment numerous variations are
possible. For example, the channel elements 24 and 32 can be
mounted directly on the shoe. Tabs could be supplied on the sole
section 12. Also, straps could be used to secure the device 10 to
the shoe instead of cement.
