[0003] Not Applicable.
BACKGROUND OF THE INVENTION
[0004] 1. Field of the Invention
[0005] The present invention relates to shoe horns and particularly
to a shoe horn device having a handle in a shoe horn configuration
with a long telescoping handle extension and a shoe horn head at an
opposite end of the handle extension which folds over the handle in
its retracted position for a more compact arrangement to fit into a
pocket or purse of a user, wherein the shoe horn head is
replaceable with other types of heads for use with the device.
[0006] 2. Description of Related Art Including Information
Disclosed Under 37 CFR 1.97 and 1.98
[0007] A shoe horn is a great aide and often necessary to assist a
user in inserting a foot into a shoe or slipping a shoe over a
foot, especially for very tight-fitting shoes. A long handled shoe
horn is a great convenience for putting on a shoe without bending
over by simply holding the shoe horn against an inside back of a
shoe from a standing position while slipping the foot into the
shoe. For people who cannot bend over, such as people with leg
injuries, or cannot easily bend over, such as elderly or other
joint stiffened people, a long handled shoe horn is a necessity for
putting on shoes without bending over.
[0008] With the current mobile lifestyle and various activities
away from home requiring having to removes shoes and put them on
again having a portable long handle shoe horn is a great
convenience to some and necessity to others as indicated above.
Some such situations include exercise classes or sports
participation, such as swimming or bowling, medical visits, or just
trying on clothing or shoes at a self-service shoe store. Prior art
devices do not address this problem in an easy-to-use compact
portable shoe horn which extends out to a useful length.
[0009] U.S. Pat. No. 6,695,182, issued Feb. 24, 2004 to Shrewsbury,
depicts an extendable shoehorn device for permitting a user to put
a shoe on a foot without having to bend over. The extendable
shoehorn device includes a handle assembly having a pocket clip
thereon. An offset shoehorn member is mounted to an end of the
handle assembly for permitting a user to more easily put a shoe on
their foot.
[0010] U.S. Pat. No. D302,490, issued Aug. 1, 1989 to Denney,
provides the ornamental design for a shoe horn.
[0011] U.S. Pat. No. 4,355,745, issued Oct. 26, 1982 to Nelson,
shows a specially constructed shoe horn for persons having limited
body bending movements. The device has an elongated pivotable
handle, which enables a person to put on footwear without
substantial bending at the waist, hips or knees.
[0012] U.S. Pat. No. 5,884,823, issued Mar. 23, 1999 to Carroll,
claims a collapsible shoe horn that includes a shoe horn tongue
having a generally thin and smooth body portion for aiding the user
in putting on a pair of shoes. The side edges of the shoe horn
tongue are slightly curved upwardly in a concave manner so that the
shoe horn tongue conforms to the shape of the heel of a human foot.
A neck portion is integral with and extends from the bottom of the
shoe horn tongue. The neck portion has a pair of opposing flanges,
each flange having a dap opening formed within the interior side
thereof for receiving opposing ends of a shoe horn handle. The dap
openings have a smooth dimple-like dap surface extending from the
outer exposed surface of each neck flange for protecting the shoe
horn user from the sharp ends of the shoe horn handle.
[0013] U.S. Pat. No. 6,386,216, issued May 14, 2002 to Cubelli,
describes a cane and grasping device provided with a shoehorn. An
upper tubular member is telescoped within a lower sleeve or sheath
having a cane foot at its lowermost end. The sleeve is adjustably
set along the member to set the length of the cane by a detent
assembly employing a pawl and aperture arrangement. An article
grasping mechanism is located at the lower end of the upper tubular
member and includes a pair of toothed jaws with meshing'teeth. The
jaws extend from the tubular member at one end, opposite a handle
attached to the tubular member at the other end. A lever is
attached at the handle end and is coupled to the jaws via cables
and pulleys. The jaws are biased open and are closed by the cables
as the handle is squeezed closed. The sleeve encloses the jaws in
the closed state when not in use. When the sleeve is removed from
juxtaposition over the jaws, the jaws are biased open by torsion
springs. The handle and lever are then used to close the open jaws
over an article to be grasped.
[0014] U.S. Pat. No. 3,788,531, issued Jan. 29, 1974 to Oldfield,
claims a collapsible shoehorn with two shoehorn curved sections
telescoping together for storage and telescoping out for usage.
[0015] U.S. Patent Application #20040255995, published Dec. 23,
2004 by Garrett, illustrates a walking stick having a
shoehorn/gripper and magnet accessories. The walking stick or cane
comprises a support having a foot at one end thereof and a handle
at the other. A gripper device adjacent the foot includes a
shoehorn assembly pivoted to the support for movement toward and
away from the foot for grasping objects between the end of the foot
and the shoehorn assembly. The gripper device is operated by a
trigger mounted adjacent the handle and a rod generally parallel to
the support. In one embodiment, the shoehorn assembly includes a
shoehorn which acts to grasp an object. The walking stick may have
an adjustable length, by providing telescoping sections.
[0016] What is needed is an easy-to-use compact portable shoe horn
which fits into a pocket or purse of a user and opens easily and
extends out into a shoe horn with a rigid elongated handle
extension of a useful length.
BRIEF SUMMARY OF THE INVENTION
[0017] An object of the present invention is to provide an
easy-to-use compact portable shoe horn with a handle in a shoe horn
configuration having a long handle extension which telescopes
closed and has a shoe horn head pivotally attached to on outer end
of the handle extension which pivots and locks in place over the
handle for a compact unit which fits into a pocket or purse of a
user for storage. and transportation and opens easily by snapping
the shoe horn end open away from the handle extension in a locked
open position with the handle extension telescoping out to form a
shoe horn with a rigid elongated handle of a useful length.
[0018] A related object of the present invention is to provide a
shoe horn shaped handle which fits comfortably in a hand of a user
and has a handle extension in the form of a series of telescoping
sleeves with a mating shoe horn shaped pivotable head on an outer
end of an outer sleeve which pivots open for use while holding the
handle and pivots closed nesting with the handle with the sleeves
all telescoped together inside the handle.
[0019] Another object of the present invention is to, provide
replaceable pivotable heads which may include a shoe horn, a back
scratcher, a pick-up magnet, a pick-up hand, or other types of
heads requiring an extended length handle.
[0020] In brief, the handle in the shape of a shoe horn has a
handle extension formed by a number of increasingly smaller sleeves
which telescope together to fit within the handle to provide a
pocket size item with the handle extension telescoped down and a
shoe horn head at an outer end of the sleeves pivoted over the
handle and which sleeves telescope out to form the handle extension
to make the handle a useful length and with the shoe horn head
pivoted open to enable a person to use the shoe horn in a standing
position.
[0021] The handle extension comprises of a series of tubular
sleeves telescoping into each other which telescope down to fit
within the shoe horn shaped handle. This particular shoe horn shape
handle serves three purposes. First, with the sleeves extended to
form the handle extension, the shoe horn shaped handle forms a self
sufficient shoe horn with a long handle even without the pivoting
shoe horn head attached to the other end of the telescoping
sleeves. Second, the shoe horn shaped handle receives the mating
pivoted shoe horn head in a highly efficient compact fit with the
two shoe horn shapes conforming to each other to cradle together in
a very compact arrangement. Third, using one of the interchangeable
heads on the other end of the rod in place of the pivoting shoe
horn head, the shoe horn shaped handle makes a handle with a very
comfortable grip fitting into the palm of the users hand enabling
easy manipulation of the pivotable shoe horn head or other
interchangeable heads.
[0022] The pivotable head is attached to an outer end of an
outermost sleeve by a pivotable means of allowing the pivotable
head to pivot open and lock in an extended work configuration and
pivot closed and lock in a folded over storage configuration and a
removable means of attaching the pivotable head to the outermost
telescoping sleeve.
[0023] A folding shoe horn is one of a number of removable
interchangeable pivotable heads attachable to the telescopic
sleeve. Other tips would include magnetic pick-up, back scratch,
golf putter, grasping device, etc.
[0024] With the telescoping rod collapsed and the shoe horn folded
over it, it then becomes pocket size. Unfolded and extended, the
shoe horn would be twenty-nine to thirty inches long.
[0025] An advantage of the present invention is that it provides a
useful long handled shoe horn which enables use in a standing
position and collapses down to fit in a pocket or purse.
[0026] Another advantage of the present invention is that it
provides a portable pocket tool with a collapsible and expansible
handle having a variety of replaceable heads for different
functions.
